FIELD

The present disclosure relates to the field of household appliances, and more particularly, to a latching structure for a cooking device and a cooking device having the latching structure.

BACKGROUND

Cooking devices such as microwave ovens, electric steam ovens, and electric ovens have become commonly used electrical appliances in contemporary family life. When heating of the food in the cooking device is completed, the food is at a high temperature. At present, most of the cooking devices can be opened by pulling a door handle or pressing a button, and a force for opening the door of the cooking device is within 25N. Under this mechanism, for a family with a child, during the use of the cooking device, the child may accidentally touch the door opening button or handle, the cooking device can be opened by lightly pressing or pulling, and there is a risk of the child being scalded by the heated food. In the cooking device in the related art, door opening operation is realized by hooking a switch assembly with a hook. With this structure, the user can easily open the door by pulling the door body or pressing the button once. A locking structure is installed on the cooking device for protecting the child from being scalded due to accidental touch, but the installation of the locking structure makes a great change to the cooking device, which leads to high cost.

REFERENCE NUMERALS

DESCRIPTION OF EMBODIMENTS

The embodiments of the present disclosure will be described in detail below, examples of the embodiments are illustrated in the accompanying drawings, throughout which the same or similar reference numerals refer to the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present disclosure, but should not be construed as limiting the present disclosure.

A latching structure10for a cooking device1and the cooking device1according to the embodiments of the present disclosure are described below with reference toFIGS.1to10.

As illustrated inFIGS.1to10, the latching structure10for the cooking device1according to the embodiments of the present disclosure is provided. The cooking device1includes a casing32and a door body31. The latching structure10includes a flipping member20, a first restoring member14, a restricting member12, and a second restoring member15.

The door body31fits with the casing32in an openable and closable manner, so that the casing32can be opened and closed through the door body31. When a user needs to use the cooking device1, the door body31can be operated to open the casing32, food can be placed in the casing32, then the casing32can be closed through the door body31, and the food can be cooked in the cooking device1.

The flipping member20is rotatably disposed on the casing32. In response to being triggered to rotate to a door-opening position, the flipping member20drives a hook of the door body31to be disengaged from a limiting portion of the casing32, and at this moment the casing32can be opened through the door body31.

That is to say, the user can change the engagement relation between the hook and the limiting portion by operating the flipping member20, and then the door body31can be moved from a position in which the casing32is closed to a position in which the casing32is opened. In this way, the casing32can be closed or opened as required by the user. When the casing32is closed by the door body31, the hook on the door body31is engaged with the limiting portion on the casing32, to ensure that the door body31is in a state in which the casing32is closed. After the user operates the flipping member20, the hook on the door body31can be disengaged from the limiting portion on the casing32, and the door body31can move to the position in which the casing32is opened.

The first restoring member14is respectively connected to the flipping member20and the casing32, and the first restoring member14can provide the flipping member20with a first restoring force for allowing the flipping member20to rotate towards a non-triggered position, so as to ensure that after the user releases the flipping member20, the flipping member20can be automatically restored to the non-triggered position, which is convenient for the user to operate the flipping member20next time.

Referring toFIGS.3to5, the restricting member12can be movably disposed on the casing32between a first position and a second position. When the restricting member12is in the first position, the restricting member12blocks the flipping member20from rotating towards the door-opening position, and when the user operates the flipping member20, since the restricting member12blocks a rotation of the flipping member20and the hook of the door body31and the limiting portion on the casing32are still in an engaged state, the door body31cannot move to the position in which the casing32is opened.

When the restricting member12is in the second position, the restricting member12can avoid the rotation of the flipping member20. When the user operates the flipping member20, the flipping member20can move to the door-opening state, thereby the flipping member20drives the hook of the door body31to be disengaged from the limiting portion on the casing32, and at this moment the door body31can move to the position where the casing32is opened.

The provided latching structure10can realize double locking of the door body31. When the casing32needs to be opened through the door body31, the user needs to move the restricting member12to the second position, and move the flipping member20to the door-opening state. The casing32can be opened only through step-by-step operations, so as to protect a child from being scalded by accidentally touching and opening the casing32.

Referring toFIGS.5and8, the second restoring member15is respectively connected to the restricting member12and the casing32, and the second restoring member15is configured to provide the restricting member12with a second restoring force for allowing the restricting member12to move towards the first position, so that the restriction member12can always block the flipping member20from moving towards the door-opening position, and each time, a press button111needs to be operated to move the restricting member12to the second position. It facilitates realizing that the door body31is opened only through step-by-step operations, and a case where the door body31is opened due to accidental touch is avoided.

The latching structure10is configured such that a restoring speed at which the flipping member20is rotated by the first restoring force towards the non-triggered position is greater than a restoring speed at which the restricting member12moves from the second position towards the first position, to allow the restricting member12to avoid the restoration of the flipping member20, and to prevent the restricting member12from blocking a rotation of the flipping member20towards the non-triggered position when the restricting member12moves from the second position to the first position, so as to prevent the restricting member12and the flipping member20from being stuck during the movement. That is to say, when the casing32needs to be opened, the user can first move the restricting member12to the second position, and then operate the flipping member20to move to the door-opening state. When the user releases the flipping member20and the restricting member12at the same time, the flipping member20is preferentially restored to the non-triggered position under the driving of the first restoring member14, and the restricting member12can smoothly be restored to the first position after the flipping member20is restored to the non-triggered position, and the restricting member12and the flipping member20do not block each other during the restoring.

With the latching structure10, on the one hand, when opening the door body31of the cooking device1, the user needs to operate on the restricting member12first in order to release the restriction on the flipping member20. Then, the flipping member20is operated to release the restriction between the hook and the limiting portion to open the door body31. In this way, the problem that a child accidentally touches the latching structure10to directly open the door body31can be avoided, and the safety of using the cooking device1is improved. On another hand, the latching structure10according to the embodiments of the present disclosure has a simple structure and low cost, which is beneficial to simplify the manufacturing process of the cooking device1and can also reduce the manufacturing cost of the cooking device1. Furthermore, the latching structure10according to the embodiments of the present disclosure is convenient to operate, is convenient for the user to use, and has a better user experience.

Therefore, the latching structure10of the cooking device1according to the embodiments of the present disclosure can lock the door body31. It is necessary to first release the restriction of the latching structure10and then open the switch lock before opening the door body31of the cooking device1. In this way, the problem that a child accidentally touches the switch lock apparatus to directly open the door body31can be avoided, and the safety of using the cooking device is improved

The latching structure10of the cooking device1according to specific embodiments of the present disclosure will be described below with reference to the accompanying drawings.

As shown inFIGS.1to10, the cooking device1includes a casing32and a door body31, and the latching structure10includes a flipping member20, a first restoring member14, a restricting member12and a second restoring member15.

For example, cooking devices1such as microwave ovens, electric steam ovens, and electric ovens have become commonly used electrical appliance in contemporary family life. When heating of the food in the cooking device1is completed, the food is at a high temperature. At present, most cooking devices1can be opened by pulling a door handle or pressing a press button111, and a force for opening the door of the cooking device is within 25N. Under this mechanism, for a family with a child, during use of the cooking device1, the child may accidentally touch the press button111or handle, the door can be opened by lightly pressing or pulling, and there is a risk of the child being scalded by the heated food. In order to solve the above problem, reference can be made toFIGS.1to3, embodiments of the present disclosure provide a latching structure10for a cooking device1.

In some embodiments of the present disclosure, the door body31is rotatably connected to the casing32, and the door body31is rotatable relative to the casing32to open or close the casing32. The door body31and the casing32can be rotatably connected through, but not limited to a hinged manner, as long as the door body31and the casing32can be rotatably connected together. In addition, in some embodiments, the door body31can be connected to the casing32in a non-detachable manner, so that the cooking device1has a good structural integrity, a firm installation, and a beautiful appearance. In some other embodiments, the door body31can be detachably connected to the casing32, so that if a structure in the casing32is damaged, the door body31can be disassembled from the casing32for maintenance.

In some embodiments of the present disclosure, the first restoring member14is a tension spring, and the user can press the flipping member20to rotate the flipping member20backward (forward and backward directions are shown inFIG.1). At this moment, the first restoring member14is elastically deformed and elongated. When the user releases the first restoring member14, the first restoring member14can pull the flipping member20with a large pulling force so that the flipping member20rotates forward. The first restoring member14always applies a forward pulling force on the flipping member20, to ensure that after the user releases the flipping member20, the first restoring member14can always have a sufficient force for driving the flipping member20to be restored back to the non-triggered position. In this way, the user can directly operate the flipping member20next time.

In some embodiments of the present disclosure, the second restoring member15is a compression spring, and the user can drive the restricting member12to move rightward. At this moment, the second restoring member15is elastically deformed and compressed. After the user releases the second restoring member15, the second restoring member15can push the restricting member12with a larger thrust so that the restricting member12moves leftward. The second restoring member15always applies a leftward thrust on the restricting member12(leftward and rightward directions are shown inFIG.1), to ensure that after the restricting member12is not operated, the second restoring member15can always have a sufficient force to drive the restricting member12to move to the first position, and the restricting member12can always block the movement of the flipping member20towards the door-opening position. In this way, the user needs to perform two operations to open the casing32.

In some embodiments of the present disclosure, the latching structure10for the cooking device1further includes a damping member133. The damping member133is respectively connected to the restricting member12and the casing32. The damping member133provides a damping force to reduce the restoring speed at which the restricting member12moves towards the first position, thereby prolonging the restoring time of the restricting member12. During a period of time during which the restricting member12moves from the second position to the first position, the flipping member20can be restored to the non-activated position.

In some embodiments, the user may first move the restricting member12from the first position to the second position, and after the user releases the restricting member12, under the blocking of the damping member133, the second restoring member15will not immediately drive the restricting member15to be restored to the first position, but instead stays in the first position for a period of time. During this period of time, the user can operate the flipping member20to rotate the flipping member20to the door-opening position and open the casing32.

With the damping member133, it facilitates reducing the user's difficulty in operation. For example, when the user can only operate the latching structure10with one hand, the setting of the damping member133can realize the step-by-step operations in different time periods. That is to say, there is no need to operate the restricting member12and the flipping member20at the same time. With one hand, the restricting member12can be operated first, and then the flipping member20can be operated to rotate the flipping member20to the door-opening position, to open the casing32.

In some embodiments of the present disclosure, the first restoring force is greater than the second restoring force, so that a restoring speed at which the flipping member20rotates towards the non-triggered position is greater than a restoring speed at which the restricting member12moves from the second position to the first position. In this way, the restricting member12can avoid the rotation of the flipping member20, and the restricting member12is prevented from blocking a rotation of the flipping member20towards the non-triggered position when the restricting member12moves from the second position towards the first position, so as to avoid the restricting member12and the flipping member20from being stuck during the movement.

In some embodiments of the present disclosure, as illustrated inFIGS.5to7and10, the restricting member12includes a first abutting portion121, and the flipping member20includes a second abutting portion221. When the restricting member12is in the first position, the second abutting portion221at least partially abuts on the first abutting portion so that the restricting member12can block the rotation of the flipping member20, the hook of the door body31and the limiting portion on the casing32are still in an engaged state, and the door body31cannot be moved to the position where the casing32is opened.

In the second position, the second abutting portion221and the first abutting portion121are completely staggered with each other, so that the restricting member12can avoid the rotation of the flipping member20, and the flipping member20can smoothly rotate to the door-opening position.

In some specific embodiments of the present disclosure, the restricting member12further includes a first avoiding portion122corresponding to the second abutting portion221. The first avoiding portion122and the first abutting portion121are staggered with each other. The flipping member20further includes a second avoiding portion222corresponding to the first abutting portion121. The second avoiding portion222and the second abutting portion221are staggered with each other. When the restricting member12is in the second position, the first abutting portion121enters the second avoiding portion222, and the second abutting portion221enters the first avoiding portion122, so that the restricting member12can avoid the rotation of the flipping member20.

It should be noted that one or more first abutting portions121and one or more first avoiding portions122may be provided, which is not limited here. Correspondingly, one or more second abutting portions221and one or more second avoiding portions222may be provided, which is not limited here. In addition, the “first abutting portion121entering the second avoiding portion222” here may mean that the first abutting portion121only enters but does not pass through the second avoiding portion222, or that the first abutting portion121enters and passes through the second avoiding portion222. Similarly, “the second abutting portion221entering the first avoiding portion122” may mean that the second abutting portion221only enters but does not pass through the first avoiding portion122, or that the second abutting portion221enters and passes through the first avoiding portion122, which is not limited here. In this way, by provision of the first avoiding portion122corresponding to the second abutting portion221and the second avoiding portion222corresponding to the first abutting portion121, when the restricting member12is in the second position, the second abutting portion221can pass through the first avoiding portion122, the first abutting portion121can pass through the second avoiding portion222, and the flipping member20can rotate freely without being blocked.

In some specific embodiments, as illustrated inFIG.10, the restricting member12includes three first abutting portions121arranged and spaced apart from each other in a left-right direction. Every two adjacent first abutting portions121define one first avoiding portion122. That is to say, the restricting member12has two first avoiding portions122provided thereon. Correspondingly, the flipping member20has three second abutting portions221provided thereon. The three second abutting portions221are arranged and spaced apart from each other in the left-right direction. Every two adjacent second abutting portions221define one second avoiding portion222. That is, the flipping member20has two second avoiding portions222provided thereon.

The restricting member12is movable in the left-right direction to move between the first position and the second position. When the restricting member12is in the first position, a position of the first abutting portion121corresponds to a position of the second abutting portion221, and a position of the first avoiding portion122corresponds to a position of the second avoiding portion222, so as to block the flipping member20through the cooperation of the first abutting portion121and the second abutting portion221.

When the restricting member12moves to the right to the second position, the first abutting portion121and the second abutting portion221both move to the right by a certain distance, so that the position of the first abutting portion121corresponds to the position of the second avoiding portion222, and the position of the second abutting portion221corresponds to the position of the first avoiding portion122. When the user operates the flipping member20, the second avoiding portion222can avoid the first abutting portion121and the first avoiding portion122can avoid the second abutting portion221. At this moment, the flipping member20can rotate smoothly to the door-opening position.

In some embodiments of the present disclosure, as illustrated inFIGS.5and8, the latching structure10for the cooking device1further includes a support base130. The support base130is disposed on the casing32and connected to the second restoring member15and the damping member133respectively. The support base130can limit the positions of the damping member133and the second restoring member15.

The restricting member12is movably engaged with the support base130, and the support base130can limit the position of the restricting member12, to prevent the restricting member12from disengaging from the support base130when the restricting member12moves between the first position and the second position.

In some optional embodiments of the present disclosure, the support base130has a guide groove134defined therein. The restricting member12has a guide portion124. The guide portion124extends into the guide groove134, and the restricting member12is movable in an extending direction of the guide groove134relative to the support base130. In this way, through the engagement between the guide portion124and the guide groove134, the restricting member12is movable relative to the support base130along a predetermined movement track.

Since the support base130is fixed relative to the casing32, and the guide groove134is defined in the support base130, which can make the structure of the guide groove134more stable, make the engagement between the guide portion124and the guide groove134more stable, and facilitate the smooth switching of the restricting member12between the first position and the second position.

In some embodiments, as illustrated inFIG.8, the guide groove134on the support base130extends in the left-right direction (the left-right direction is shown inFIG.1). Referring toFIG.10, the restricting member12has a guide portion124provided on a side thereof facing towards the support base130. The guide portion124is formed as a protrusion extending towards the guide groove134. The guide portion124can extend into the guide groove134, and is movable along the guide groove134in the left-right direction, to realize the smooth movement of the restricting member between the first position and the second position.

In some other optional embodiments of the present disclosure, the support base130has a guide portion124formed thereon. The restricting member12has a guide groove134defined therein. The guide portion124extends into the guide groove134, and the restricting member12is movable in an extending direction of the guide groove134relative to the support base130. In this way, through the engagement between the guide portion124and the guide groove134, the restricting member12is movable relative to the support base130along a predetermined movement track.

It should be noted that one or more guiding portions124may be provided, which is not limited here. In the embodiment illustrated inFIG.3, two guide portions124are provided. The provision of a plurality of guide portions124facilitates to enhance the stability of the engagement between the restricting member12and the support base130, so that the support base130can move smoothly between the first position and the second position.

In addition, a length of the guide groove134can limit a movable range of the restricting member12. When a movable path of the restricting member12needs to be shortened, the length of the guide groove134can be shortened, which facilitates the miniaturization design of the latching structure10.

In some embodiments of the present disclosure, as illustrated inFIGS.5and8, the support base130includes a cover body131and a bracket132. An accommodating chamber1323is formed between the cover body131and the bracket132. The accommodating chamber1323is configured to accommodate the damping member133to limit the position of the damping member133. Since the damping member133is connected to the restricting member12, and the damping member133is disposed in the accommodating chamber1323, the restricting member12is prevent from driving the damping member133to move when the restricting member12moves. In this way, the position of the damping member133can be limited, ensuring that the damping member133can always provide a damping force to reduce the restoring speed of the restricting member12moving towards the first position.

In some embodiments, as illustrated inFIGS.8and10, the damping member133has a head portion1331and a rod portion1332. The restricting member12has a snap groove1231. The rod portion1332is accommodated in the accommodating chamber1323that is defined by the bracket132and the cover body131. The rod portion1332is positioned fixedly relative to the bracket132and the cover body131. The head portion1331protrudes out of the accommodating chamber1323. The head portion1331can extend into the snap groove1231of the restricting member12. The head portion1331is elastically engaged with the snap groove1231.

In some examples, when the restricting member12is in the first position, the head portion1331is exposed outside the snap groove1231. When the restricting member12is in the second position, the head portion1331extends into the snap groove1231. That is, when the user moves the restricting member12from the first position to the second position, the head portion1331is gradually engaged with the snap groove1231. At this moment, the user needs to apply a certain force to overcome the damping force of the damper133on the restricting member12, so that the restricting member12can move to the second position. The user generally will not apply a large force on the restricting member12when the user has an accidental touch, and the provision of the damping member133can further avoid the movement of the restricting member12caused by the user's accidental touch.

When the user releases the restricting member12, the second restoring force caused under the driving of the second restoring member15gradually overcomes the damping force caused by the damping member133, so that the restricting member12is restored to the first position, and the head portion1331is gradually disengaged from the snap groove1231.

In some embodiments, the bracket132can be fixed to the casing32by means of screw connection and/or snap connection. The cover body131is fixedly mounted on the bracket132by means of screw connection and/or snap connection, so as to stably fix the support base130on the casing32. As illustrated inFIGS.5and8, the guide groove134may be formed on the bracket132and/or the cover131to prevent the bracket132and/or the cover body131from blocking the movement of the restricting member12.

In some embodiments of the present disclosure, as illustrated inFIGS.4to6, the latching structure10for the cooking device1further includes a fixing base112and a press button111. The fixing base112has a first guide groove1123running therethrough. The fixing base112is disposed on the casing32. The press button111extends into the first guide groove1123. The press button111is movable relative to the fixing base112in a direction, in which the first guide groove1123runs through the fixing base112, to push the restricting member12to move. The user can operate the press button111to operate on the movement of the restricting member12, to realize the movement of the restricting member12between the first position and the second position, thereby improving the operation comfort of the user.

In some embodiments, the direction in which the first guide groove1123runs through the fixing base112extends in the left-right direction, so that the press button111is movable in the left-right direction so as to push the restricting member12to move in the left-right direction, thereby realizing the smooth movement of the restricting member12between the first position and the second position.

In some optional embodiments of the present disclosure, as illustrated inFIGS.8to9, the press button111includes a first action member1111and a force applying member1112. The first action member1111matches the first guide groove1123, and the first guide groove1123can limit a moving direction of the first action member1111and further limit a moving direction of the press button111. When the press button111is stressed, the press button111can move along a predetermined movement track to avoid a problem that the movement of the press button111deviates from the predetermined movement track, resulting in that the restricting member12cannot be pushed to move along a predetermined route. In this way, it is ensured that the restricting member12can move smoothly in a predetermined direction.

The first action member1111has a pressing surface. The force applying member1112is connected to a surface of the first action member1111facing away from the pressing surface. The force applying member1112interacts with the restricting member12to push the restricting member12to move. The pressing surface is configured to contact the user, to receive the user's operation. That is to say, the user can drive the first action member1111to move through the pressing surface, and then the first action member1111drives the force applying member1112to move. Since the force applying member1112interacts with the restricting member12, the force applying member1112, when moving, can drive the restricting member12to move. In this way, it is ensured that the restricting member12can move from the first position to the second position under the operation of the user.

In some embodiments, as illustrated inFIGS.8and9, the force applying member1112is located at an end of the first action member1111facing away from a rotation axis of the flipping member20. In this way, a case where the rotation path of the flipping member20is blocked by the force applying member1112is avoided, so as to make the force applying member1112better avoid the rotation path of the flipping member20.

In some optional embodiments of the present disclosure, the first guide groove1123has a second guide groove1124defined on each of opposite side walls thereof. The press button111further includes a guide member1113protruding relative to the first action member1111. The guide member1113extends into the second guide groove1124and is movable relative to the fixing base112in an extending direction of the second guide groove1124. On the one hand, the provision of the second guide groove1124can limit the position of the press button111, and prevent the press button111from falling from the fixing base112. On the other hand, the provision of the second guide groove1124can ensure that the press button111can move stably in the extending direction of the second guide groove1124under the operation of the user.

In some embodiments, as illustrated inFIG.9, the direction in which the first guide groove1123runs through the fixing base112extends in the left-right direction. The opposite side walls of the first guide groove1123include upper and lower side walls and front and rear side walls of the fixing base112(the up-down direction and the front-rear direction are shown inFIG.1, and it should be understood here that the above direction limitations are only for facilitating the description of the drawings, and do not limit the actual setting position and direction of the latching structure10for the cooking device1). One or more side walls in the upper and lower side walls and the front and rear side walls of the fixing base112, or all side walls of the fixing base112has a second guide groove1124defined therein, and the second guide groove1124extends in the left-right direction.

The press button111has a guide member1113provided on a corresponding position. When the first action member1111on the press button111is installed in the first guide groove1123, the guide member1113on the press button111is correspondingly installed in the second guide groove1124. The first guide groove1123and the second guide groove1124jointly limit the moving direction of the press button111to ensure the smooth movement of the press button111and thus the smooth movement of the restricting member12.

In some optional embodiments of the present disclosure, as illustrated inFIGS.4to7, the latching structure10for the cooking device1further includes a disabling member113. The disabling member113is detachably engaged with the fixing base112. The disabling member113presses, in response to being engaged with the fixing base112, the press button111to cause the restricting member12to be maintained in the second position against the second restoring force. In this case, the user can rotate the flipping member20to the door-opening state without operating the restricting member12, to adapt to the different needs of different users.

When the user does not need to restrict the rotation of the flipping member20, the disabling member113can be installed on the fixing base112. In this case, the restricting member12is fixed in the second position, and the user can operate the flipping member20at any time to open the door body31.

When the user needs to restrict the rotation of the flipping member20, the disabling member113can be removed from the fixing base112. The second restoring member15drives the restricting member12to be restored to the first position, so as to drive the press button111to be restored in an initial position. In this case, the restricting member12can block the flipping member20from rotating to the door-opening position.

In some specific embodiments of the present disclosure, the disabling member113has an elastic protrusion1133provided thereon. The elastic protrusion1133is engaged with the second guide groove1124in such a manner that the disabling member113is detachable relative to the fixing base112, which is convenient for the user to operate the disabling member113to change the position of the press button111so as to change the position of the restricting member12and adjust the restricting state of the restricting member12on the flipping member20.

In some embodiments, the direction in which the first guide groove1123runs through the fixing base112extends in a front-rear direction, and the restricting member12is movable between the first position and the second position in the front-rear direction. The press button111is disposed in the first guide groove1123of the fixing base112. When the restricting member12is in the first position, a left end surface of the press button111is flush with a left end surface of the fixing base112. When the user installs the disabling member113in the first guide groove1123in the left-right direction, the disabling member113drives the press button111to move to the right, and drives the restricting member to move to the right.

When the disabling member113is installed in place, the elastic protrusion1133on the disabling member113is engaged in place with the second guide groove1124and the disabling member113is fixed in that place. In this case, the restricting member12is in the second position and is fixed in the second position, and no longer restricts the rotation of the flipping member20.

In some embodiments, the disabling member113includes an operating portion1131and an engaging portion1132. The elastic protrusion1133is disposed on the engaging portion1132. When the disabling member113is installed in place in the first guide groove1123, the operating portion1131is exposed outside the first guide groove1123. When the disabling member113needs to be removed from the fixing base112, the disabling member can be taken out of the first guide groove1123through the operating portion1131, which is convenient for the user to remove and install the disabling member.

The cooking device1according to the embodiments of the present disclosure is described below. The cooking device1according to the embodiments of the present disclosure includes a casing32, a door body31, and the latching structure10for the cooking device1according to the above-described embodiments of the present disclosure.

The casing32has a limiting portion provided thereon. The door body31is engaged with the casing32in an openable and closable manner. The door body31has a hook provided thereon. The latching structure10is disposed on the casing32. The flipping member20is engaged with the hook. The flipping member20is configured to drive, in response to being triggered to rotate to the door-opening position, the hook to be detached from the limiting portion, so as to realize the opening or closing of the casing32through the door body31.

In some embodiments, the casing32further has a rotating member provided thereon. An end of the flipping member20is in contact fit with the rotating member. The door body31is disposed on a front side of the casing32. The hook has a rear surface formed in an arc shape and a front surface extending in the up-down direction. When the casing32is closed by the door body31, the hook is engaged with the limiting portion. In this case, when the user pulls the door body31, the front surface of the hook is engaged with the limiting portion, and the hook cannot be disengaged with the limiting portion.

When the user presses the flipping member20backward, an end of the flipping member20in contact with the rotating member rotates upward to drive the rotating member to rotate upward. When the rotating member rotates to a certain position, it drives the hook to rotate upward. That is to say, during the rotation process, the flipping member20can drive the hook to rotate upward through the rotating member, so that the hook is disengaged from the limiting portion. In this case, the user can pull the door body31to open the casing32, or when the user presses the flipping member20, the door body31automatically pops forward and opens the casing32.

When the user needs to close the casing32, the door body31can be operated to move backward. At this moment, the rear surface of the hook is engaged with the limiting portion. When the user presses the door body31backward, since the rear surface of the hook is formed in an arc shape, the hook can be rotated upward by a reaction force of the limiting portion acting thereon. After the hook is rotated upward by a certain distance, when the rear surface of the hook is disengaged from the limiting portion, the hook is disengaged with the limiting portion. At this moment, the casing32can be closed by the door body31.

By using the latching structure10for the cooking device1according to the embodiments of the present disclosure, the cooking device1according to the embodiments of the present disclosure has the advantages of locking the door body31, protecting a child from being scalded due to accidental touch, having a relatively simple structure, and facilitating cost reduction.

In some embodiments of the present disclosure, the flipping member20is exposed to a front surface of the casing32. The pressing surface of the press button111is exposed to a side wall of the casing32, so that the user can operate the flipping member20and the press button111.

In some embodiments, as illustrated inFIG.1, the flipping member20is disposed on a lower left end of a front surface of the casing32. The press button111is disposed on a lower right end of a left surface of the casing32. On the one hand, it is convenient for the user to operate the flipping member20and the press button111, and on the other hand, the flipping member20and the press button111are arranged in adjacent areas, so that the restricting member12can be driven to be engaged with the flipping member20through the press button111.

In some embodiments of the present disclosure, the casing32has a control box2provided thereon. The control box2is configured to control an operation state of the cooking device1. The latching structure10is located on a rear side of the control box2. The user can operate the control box2to operate on the working state of the cooking device1. The latching structure10is disposed on the rear side of the control box2, so as to ensure the overall aesthetics of the cooking device1.

In some embodiments of the present disclosure, the casing32has a door-opening button33provided thereon. The door-opening button33is configured to trigger the flipping member20. The casing32has a press button111provided on a side wall thereof adjacent to the door-opening button33. The press button111is configured to push the restricting member12to move, which is convenient for the user to operate the door-opening button33and the press button111.

In some embodiments, as illustrated inFIG.1, the door-opening button33is exposed to the front surface of the casing32. The pressing surface of the press button111is exposed to the side wall of the casing32. The door-opening button33is disposed on a lower left end of the front surface of the casing32. The press button111is disposed on a lower right end of the left surface of the casing32. On the one hand, it is convenient for the user to operate the door-opening button33and the press button111at the same time. On the other hand, the door-opening button33and the press button111are arranged in adjacent areas, so that the restricting member12can be driven to be engaged with the flipping member20through the press button111.

It can be understood that the latching structure10for the cooking device1of the present disclosure can not only be applied in the cooking device1according to the embodiments of the present disclosure, but also can be applied in other small household appliances, such as refrigerators, washing machines, etc., which need to protect children from open the door due to accidental touch.

The latching structure10for the cooking device1and the cooking device1according to the embodiments of the present disclosure are described below with reference toFIGS.11-25.

As illustrated inFIGS.11to25, a latching structure10for a cooking device1is provided according to the embodiments of the present disclosure. The cooking device1includes a casing32and a door body31, and the latching structure10includes a flipping member100, a base200, a press button111and a restricting member12.

The door body31is engaged with the casing32in an openable and closable manner, so that the casing32can be opened or closed through the door body31. When the user needs to use the cooking device1, the user can operate the door body31to open the casing32, place food in the casing32, then close the casing32through the door body31, and cook the food using the cooking device1. The latching structure10includes a flipping member100, a base200, a press button111, and a restricting member12. The flipping member100is rotatably disposed on the casing32. The flipping member100drives, in response to being triggered to rotate into a door-opening position, a door hook312of the door body31to rotate so as to be detached from a limiting portion21on the casing32. At this moment, the casing32can be opened through the door body31.

In some embodiments, the flipping member100is directly engaged with the door hook312, and the flipping member100can directly drive the door hook312to rotate. In some other embodiments, as illustrated inFIG.16, the flipping member100and the door hook312are engaged with each other indirectly. For example, the flipping member100is engaged with the door hook312through a rotating member22, the flipping member100can drive the rotating member22to rotate, and then the rotating member22drives the door hook312to rotate.

That is to say, the user can change the engagement relation between the door hook312and the limiting portion21by operating the flipping member100, so that the door body31can move from a position where the casing32is closed to a position where the casing32is opened. The casing32is closed or opened according to the needs of the user. When the casing is closed by the door body31, the door hook312on the door body31is engaged with the limiting portion21on the casing32to ensure that the door body31is in a state in which the casing32is closed. After the user operates the flipping member100, the door hook312on the door body31can be disengaged from the limiting portion21on the casing32, and the door body31can move to the position where the casing32is opened.

Referring toFIGS.11to12, the base200is disposed on the casing32, and the press button111is movably disposed on the base200. The user can operate the press button111to move the press button111. The base200can limit a position of the press button111, so that the press button111can be disposed on the casing32. Since the flipping member100is also disposed on the casing32, it is convenient for the user to operate the press button111and the flipping member100at the same time.

In addition, in some embodiments, as illustrated inFIG.20, the press button111is disposed in the base200, the press button111is engaged with the base200, and the base200can limit a moving direction of the press button111, so as to avoid a case where the press button200falls off from the base200when the user operates the press button111.

Referring toFIGS.15to16and21, the restricting member12is engaged with the press button111to move synchronously with the press button111. The press button111, when moving, can drive the restricting member12to move between a locking position and an unlocking position. When the restricting member12is in the locking position, the restricting member12is located on a rotation path of the flipping member100to block the flipping member100from rotating towards the door-opening position. In this case, when the user operates the flipping member100, since the restricting member12blocks the rotation of the flipping member100, the door hook312of the door body31is still engaged with the limiting portion21on the casing32, and the door body31cannot move to the position where the casing32is opened.

In some embodiments, when the restricting member12is in the locking position, an end of the restricting member12always abuts on the flipping member100, the restricting member12can limit the position of the flipping member100, the user cannot operate the flipping member100to rotate in the casing32, and the door hook312of the door body31and the limiting portion21on the casing32are in an engaged state. In some other embodiments, when the restricting member12is in the locking position, there is a gap between the restricting member12and the flipping member100, and when the user operates the flipping member100, and the flipping member100rotates by a certain distance, an end of the restricting member12abuts on the flipping member100. Although the flipping member100rotates by a certain distance, it is not enough for the flipping member100to rotate into the door-opening position, and the door hook312of the door body31and the limiting portion21on the casing32are still in the engaged state.

In the unlocking position, as illustrated inFIGS.17to18, the restricting member12avoids the flipping member100. When the user operates the flipping member100, the flipping member100can move to the door-opening state, thereby driving the door hook312of the door body31to disengage from the limiting portion21on the casing32, and the door body31can move to the position where the casing32is opened.

The latching structure10set in this way can realize the double locking of the door body31. When the casing32needs to be opened through the door body31, the user needs to move the restricting member12to the unlocking position, and move the flipping member100to the door-opening state. The casing32can be opened only through step-by-step operations, so as to protect a child from being scalded when the casing32is opened due to accidental touch.

In addition, the latching structure10can lock the flipping member100by the provision of the base200, the press button111, and the restricting member12, and the provision of the flipping member100realizes the locking of the door body31and the casing32. The latching structure10has a relatively simple structure, has a small modification to the cooking device1, and has a small number of parts, which facilitates reducing the production cost of the latching structure10.

Therefore, the latching structure10for the cooking device1according to the embodiments of the present disclosure has the advantages of locking the door body31, protecting children from being scalded due to accidental touch, having a relatively simple structure, and facilitating cost reduction.

The latching structure10for the cooking device1according to specific embodiments of the present disclosure is described below with reference to the accompanying drawings.

As illustrated inFIGS.11to25, the cooking device1includes a casing32and a door body31, and the latching structure10includes a flipping member100, a base200, a press button111and a restricting member12.

In some embodiments of the present disclosure, the press button111is rotatably disposed on the base200, and the press button111is configured to rotate to drive the restricting member12to switch between an enabled state and a disabled state. When the restricting member12is in the enabled state, the press button200moves to drive the restricting member12to move between the locking position and the unlocking position. When the restricting member12is in the disabled state, with reference toFIGS.19to20, the restricting member12avoids the flipping member100, and the user can rotate the flipping member100into the door-opening state without operating the restricting member12, so as to meet the different needs of different users.

When the user does not need to restrict the rotation of the flipping member100, the user can rotate the press button111to drive the restricting member12to switch to the disabled state. In this case, the restricting member12avoids the flipping member100, and the user does not need to perform any further operations on the restricting member12and instead can directly operate the flipping member100, so that the flipping member100rotates to the door-opening position to open the casing32.

When the user needs to restrict the rotation of the flipping member100, the user can rotate the press button111to drive the restricting member12to switch to the enabled state. In this case, the restricting member12blocks the flipping member100from rotating to the door-opening position. When the user needs to open the casing32, the user needs to move the restricting member12to the unlocking position first, and then operate the flipping member100to rotate to the door-opening position to open the casing32.

In some embodiments of the present disclosure, with reference toFIG.23, the latching structure10for the cooking device1further includes a second restoring member15. The second restoring member15is connected to the press button111and the base200respectively. The second restoring member15provides a restoring force to the press button111to allow the press button111to move into an initial position, and to drive the restricting member12to move to the locking position through the press button111. The restricting member12can always block the flipping member100from moving towards the door-opening position. Each time, the press button111needs to be operated to move the restricting member12into the unlocking position, so that the door body31is opened through step-by-step operations each time, and the door body31is prevented from being opened due to accidental touch.

In some embodiments, as illustrated inFIGS.15to18, when the restricting member12is in the enabled state and the user operates the press button111to move in the base200, the press button111drives the restricting member12to move between the locking position and the unlocking position. When the press button111drives the restricting member12to move into the unlocking position, the user can operate the flipping member100to rotate the flipping member100into the door-opening position, so that the door hook312of the door body31is disengaged from the limiting portion21on the casing32, and the casing32can be opened.

When the user releases the press button111, the second restoring member15can provide a restoring force to the press button111to allow the press button111to move into the initial position, and then the restricting member12is driven by the press button111to move to the locking position. In this way, it is ensured that each time, in order to open the door body31, it is necessary to operate the press button111and the flipping member100, to prevent the door body31from being opened due to accidental touch.

In some examples, the second restoring member15is a compression spring. The user can press the press button111to move the press button111to the right. At this moment, the second restoring member15is elastically deformed and compressed, so that the second restoring member15always has a leftward thrust on the press button111(the left-right direction is as shown inFIG.13). In this way, after the user releases the press button111, the second restoring member15can always have an enough force to drive the press button111to be restored to the initial position, and then drive the restricting member12to move to the locking position through the press button111.

In some embodiments of the present disclosure, with reference toFIGS.22to23, the latching structure10for the cooking device1further includes a first restoring member520. The first restoring member520is engaged with the restricting member12and the base200respectively. The first restoring member520provides the restricting member12with a torsion force for allowing the restricting member12to rotate towards the enabled state. On the one hand, it can ensure that when the restricting member12is not operated, the restricting member12will not automatically rotate to the disabled state, and on the other hand, it can ensure that when the restricting member12is in the locking position, the restricting member12has a sufficient force on a side thereof facing towards the flipping member100to block the flipping member100from rotating towards the door-opening position.

In some specific embodiments, the first restoring member520is a torsion spring, so as to provide the restricting member12with a torsion force for allowing the restricting member12to rotate towards the enabled state by using the torsion spring.

In some embodiments, with reference toFIG.23, the latching structure10further includes a circlip540. The circlip540and the first restoring member520are both sleeved on the press button111. The circlip540fits with the first restoring member520. The circlip540can limit the position of the first restoring member520to prevent the first restoring member520from disengaging from the restricting member12and the base200.

In some embodiments, with reference toFIGS.24to25, the restricting member12has a mounting hole410defined therein. The base200has a mounting groove2331defined thereon. A first end of the first restoring member520extends into the mounting hole410, and a second end of the first restoring member520is engaged with the mounting groove2331. When the user operates the press button111to move, the press button111drives the restricting member12to move, and the first restoring member520moves along with the restricting member12, the second end of the first restoring member520is movable in the mounting groove2331, to ensure that the first restoring member520can smoothly move with the restricting member12, and the first restoring member520always provides the restricting member12with a torque for allowing the restricting member12to rotate to the locking position.

In some optional embodiments, a length of the mounting groove2331is adapted to a movable distance of the press button111, to ensure that during the movement of the press button111, the second end of the first restoring member520can move smoothly in the mounting groove2331, thereby preventing the first restoring member520from being stuck in the mounting groove2331to affect the movement of the press button111and the restricting member12.

In some embodiments of the present disclosure, with reference toFIGS.23to24, the base200has a first limiting portion201and a second limiting portion202provided thereon. The first limiting portion201is engaged with or disengaged from the restricting member12. The second limiting portion202is engaged with or disengaged from the restricting member12. When the restricting member12is in the enabled state, the first limiting portion201is engaged with the restricting member12to guide a moving direction of the restricting member12to ensure that the restricting member12can move smoothly between the locking position and the unlocking position. When the restricting member12is in the disabled state, the second limiting portion202is engaged with the restricting member12to position the restricting member12so that the restricting member12can be maintained in the disabled state.

In some embodiments, the restricting member12is movable between the first limiting portion201and the second limiting portion202, and the restricting member12can be switched between the enabled state and the disabled state. When the restricting member12is in the enabled state, the restricting member12is engaged with the first limiting portion201. In this case, the user can operate the press button111to move and then rotate in a positive direction, so as to drive the restricting member12to move in a direction away from the base200and then rotate in a positive direction, so that the restricting member12is disengaged from the first limiting portion201. When the user continues to operate the press button111to move into the initial position, the restricting member12can be driven to move to the second limiting portion202and to be engaged with the second limiting portion202, so that the restricting member12is in the disabled state.

When the user needs to move the restricting member12from the disabled state to the enabled state, in some embodiments, the user can operate the press button111to move and then rotate in an opposite direction, so as to drive the restricting member12to move in a direction away from the base200and then rotate in an opposite direction, so that the restricting member12is disengaged from the second limiting portion202. After the user releases the press button111, the restricting member12is driven by the second restoring member15to move to the first limiting portion201and to be engaged with the first limiting portion201, so that the restricting member12is in the enabled state.

In some other embodiments, the user can operate the press button111to move and then release the press button111. In this case, the first restoring member520can drive the restricting member12to rotate in an opposite direction, so that the restricting member12is disengaged from the second limiting portion202. Under driving by the second restoring member15, the restricting member12moves to the first limiting portion201and is engaged with the first limiting portion201, so that the restricting member12is in the enabled state.

In some optional embodiments of the present disclosure, the base200has a first limiting post221, a second limiting post222, and a third limiting post223provided thereon. The first limiting post221, the second limiting post222, and the third limiting post223are arranged at intervals in a rotation direction of the press button111. The first limiting portion201is defined by the first limiting post221and the second limiting post222, and the second limiting portion202is defined by the second limiting post222and the third limiting post223.

In some embodiments, as illustrated inFIG.24, the first limiting post221and the second limiting post222extend in the left-right direction (the left-right direction is as shown inFIG.22), and the first limiting post221and the second limiting post222define the first limiting portion201extending in the left-right direction. When the restricting member12is engaged with the first limiting portion201, and the user operates the press button111to move the press button111in the left-right direction, the press button111can drive the restricting member12to move in the left-right direction in the first limiting portion201, and the first limiting portion201can limit the moving direction of the restricting member12, so as to prevent the restricting member12from rotating when the restricting member12moves in the first limiting portion201.

The third limiting post223extends in the left-right direction, and the second limiting post222and the third limiting post223define the second limiting portion202extending in the left-right direction. When the restricting member12is engaged with the second limiting portion202and the user operates the press button111to move the press button111in the left-right direction, the press button111can drive the restricting member12to move in the left-right direction, so that the restricting member12is movable in the left-right direction in the second limiting portion202, and the second limiting portion202can limit the moving direction of the restricting member12to prevent the restricting member12from rotating when the restricting member12moves in the second limiting portion202.

In some examples, as illustrated inFIGS.22and24, both the first limiting post221and the second limiting post222are disposed on a right end surface of the base200, the first limiting post221is disposed on a front side of the second limiting post222(in the front-rear direction as shown inFIG.22), and the third limiting post223is disposed on a lower end of the second limiting post222. The first limiting post221and the third limiting post223each has a length greater than a length of the second limiting post222. It should be understood here that the lengths of the first limiting portion201and the second limiting portion202in the left-right direction depend on the length of the second limiting post222in the left-right direction.

In some embodiments, when the user needs to move the restricting member12from the first limiting portion201to the second limiting portion202, the restricting member12is initially in the locking position, and the restricting member12is in the first limiting portion201, the user operates the press button111to move by a certain distance to the right, to drive the restricting member12to move by a certain distance to the right. When the restricting member12moves to the right and exceeds the second limiting post222, the restricting member12is disengaged from the first limiting portion201.

The length of the first limiting post221in the left-right direction is greater than the length of the second limiting post222in the left-right direction. On the one hand, it is ensured that after the restricting member12is disengaged from the first limiting portion201, the restricting member12can still move in the left-right direction along the first limiting post221. On the other hand, since the first restoring member520always drives the restricting member12to rotate towards the enabled state, the first limiting post221can limit the rotatable direction of the restricting member12.

After the restricting member12is disengaged from the first limiting portion201, the user can rotate the press button111backward to drive the restricting member12to rotate backward. In this case, the user continues to operate the press button111to move to the left, so as to drive the restricting member12to move to the second limiting portion202in the left-right direction.

The length of the third limiting post223in the left-right direction is greater than each of the lengths of the second limiting post222and the first limiting post221in the left-right direction. On the one hand, it can limit a rotatable range of the restricting member12and prevent the restricting member12from rotating backward by an excessively large angle to disengage from the base200. On the other hand, it can guide the moving direction of the restricting member12, to ensure that the restricting member12moves smoothly in the left-right direction along the third limiting post223to the second limiting portion202.

In some embodiments, the third limiting post223has a mounting groove2331defined thereon. A first end of the first restoring member520is engaged with the restricting portion, a second end of the first restoring member520is engaged with the mounting groove2331, and the first restoring member520always drives the restricting member12to rotate towards the enabled state.

When the user needs to move the restricting member12from the second limiting portion202to the first limiting portion201, the restricting member12is initially in the disabled stat, and the restricting member12is in the second limiting portion202, the user operates the press button111to move to the right by a certain distance so that the restricting member12moves to the right and exceeds the second limiting post222, and the restricting member12is disengaged from the second limiting portion202. After the restricting member12is disengaged from the second limiting portion202, the first restoring member520drives the restricting member12to rotate forward, so that the restricting member12rotates to a position where the restricting member12is engaged with the first limiting post221. After the user releases the press button111, the press button111is driven by the second restoring member15to move to the initial position, so as to drive the restricting member12to move into the first limiting portion201.

In some optional embodiments of the present disclosure, with reference toFIGS.23to24, the base200includes a cover body210and a fixing base220. The cover body210has a pressing hole211. The fixing base220is fixed on the cover body210. The press button111is disposed in the cover body210and is directly opposite to the pressing hole211. On the one hand, the pressing hole211can limit the movable direction of the press button111, and on the other hand, it facilitates the user to operate the press button111through the pressing hole211.

In addition, the press button111partially extends through the fixing base220to be engaged with the restricting member12, so that when the user operates the press button111, the press button111drives the restricting member12to move or rotate. The first limiting portion201and the second limiting portion202are disposed on a side wall of the fixing base220facing away from the cover body210, so that the positions of the first limiting portion201and the second limiting portion202correspond to the position of the restricting member12. It is ensured that the first limiting portion201and the second limiting portion202can limit the movement or rotation of the restricting member12.

In some embodiments, the restricting member12is sleeved on the press button111and is in key fit with the press button111, to ensure that the press button111, when moving or rotating, can drive the restricting member12to move or rotate.

In some specific embodiments of the present disclosure, the cover body210and the fixing base220are in snap fit with each other. As illustrated inFIG.24, the cover body210has a plurality of snap holes212, and the plurality of snap holes212is arranged circumferentially on side walls of the cover body210. Snap portions224are disposed at a corresponding position on the fixing base220. Each snap portion224can be engaged with the snap hole212to fix the fixing base220on the cover body210.

In some embodiments of the present disclosure, with reference toFIG.20, the latching structure10for the cooking device1further includes a third restoring member530. The third restoring member530is connected to the flipping member100and the casing32. The third restoring member530provides the flipping member100with a restoring force for allowing the flipping member100to rotate towards a non-triggered position. In this way, it is ensured that after the user releases the flipping member100, the flipping member100can automatically restore to the non-triggered position, which is convenient for the user to operate the flipping member100next time.

In some embodiments, the third restoring member530is a tension spring. The user can press the flipping member100to rotate the flipping member100backwards, so that the third restoring member530is elastically deformed and elongated, and the third restoring member530always has a forward pulling force on the flipping member100. In this way, it is ensured that after the user releases the flipping member100, the third restoring member530can always have a sufficient force to drive the flipping member100to be restored to the initial position.

In some optional embodiments of the present disclosure, the latching structure10is configured in a manner that during the rotation of the flipping member100toward the non-triggered position, the flipping member100blocks the movement of the restricting member12towards the locking position, so as to ensure that the flipping member100can rotate preferentially to the non-triggered position, and prevent the restricting member12from blocking the rotation of the flipping member100when the restricting member12moves from the unlocking position to the rotating position.

In some embodiments, during rotation of the flipping member100to the non-triggered position, the restricting member12is between the unlocking position and the locking position. In this case, the restricting member12will not block the rotation of the flipping member100, so that the flipping member100can rotate smoothly to the non-triggered position. After the flipping member100rotates to the non-triggered position, the restricting member12can move to the locking position to restrict the rotation of the flipping member100again.

In some other optional embodiments of the present disclosure, the latching structure10is configured in a manner that the restricting member12avoids the rotation of the flipping member100, so that the flipping member100can smoothly rotate to the non-triggered position.

In some embodiments, during the rotation of the flipping member100to the non-triggered position, the restricting member12is in the unlocking position to avoid the rotation of the flipping member100, and the restricting member12will not block the rotation of the flipping member100, so that the flipping member100can smoothly rotate to the non-triggered position. After the flipping member100rotates to the non-triggered position, the restricting member12moves to the locking position, to restrict the rotation of the flipping member100again.

In some optional embodiments of the present disclosure, the flipping member100has an abutting-stopping portion110and an avoidance space120provided thereon. The abutting-stopping portion110and the avoidance space120are disposed in sequence in the moving direction of the press button111. When the restricting member12is in the locking position and the flipping member100is triggered, the restricting member12abuts on the abutting-stopping portion110and is stopped by the abutting-stopping portion, so as to block the flipping member100from rotating towards the door-opening position through the engagement of the limiting portion21and the abutting-stopping portion110.

When the restricting member12is in the unlocking position, the restricting member12directly faces the avoidance space120, so that the restricting member12can avoid the rotation of the flipping member100, and the flipping member100can smoothly rotate to the door-opening position.

In some embodiments, the restricting member12is movable in the left-right direction, and the abutting-stopping portion110and the avoidance space120are arranged in sequence from left to right. When the restricting member12is in the enabled state, the restricting member12is located in the locking position initially, and the restricting member12corresponds to the position of the abutting-stopping portion110, so that when the flipping member100is triggered, the restricting member12is engaged with the abutting-stopping portion110, and the flipping member100is blocked from rotating towards the door-opening position by using the abutting-stopping portion110.

The user can move the restricting member12to the right by operating the press button111, so as to move the restricting member12to the unlocking position. In this case, the position of the restricting member12corresponds to the position of the avoidance space120, to avoid the rotation of the flipping member100and allow the flipping member100to smoothly rotate to the door-opening position. After the user releases the press button111, the restricting member12is driven by the second restoring member15to move to the right to the locking position, so that the restricting member12corresponds to the position of the abutting-stopping portion110again.

In some specific embodiments of the present disclosure, the latching structure10further includes a second restoring member15and a third restoring member530. The second restoring member15is connected to the press button111and the base200respectively, and the second restoring member15provides a restoring force to the press button111to allow the restricting member12to move into the locking position, which is convenient for the user to re-operate the press button111in subsequent operations and drive the restricting member12to move to the avoidance position, realizing the step-by-step operations of opening the casing32.

The third restoring member530is connected to the flipping member100and the casing32. The third restoring member530provides the flipping member100with a restoring force for allowing the flipping member100to rotate towards the non-triggered position. On the one hand, it facilitates the flipping member100to automatically restore to the non-triggered position, so as to be convenient for the user to operate the flipping member100next time. On the other hand, it can prevent the flipping member100from affecting the movement of the restricting member12, and ensure that the restricting member12can smoothly move to the locking position.

When the flipping member100rotates towards the non-triggered position, the second restoring member15pulls the press button111in such a manner that the restricting member12is brought into contact with a side wall of the abutting-stopping portion110facing towards the avoidance space120until the restricting member12directly faces the abutting-stopping portion110. In this way, it is ensured that after the user releases the press button111and the flipping member100, the flipping member100can smoothly rotate to the door-opening position, and the restriction member12is prevent from being stuck on the side wall of the abutting-stopping portion110facing towards the avoidance space120to affect the rotation of the flipping member100.

In some embodiments, the flipping member100can rotate in the front-rear direction, the press button111can drive the restricting member12to move in the left-right direction, and an end of the abutting-stopping portion110facing towards the avoidance space is formed into a rounded corner. In this way, it is ensured that when the restricting member12moves in the left-right direction, the flipping member100rotates in the front-rear direction, and the restricting member12is in contact with the side wall of the abutting-stopping portion110facing towards the avoidance space120, the restricting member12will not jam the abutting-stopping portion110, so as to ensure the smooth movement of the restricting member12and the smooth rotation of the abutting-stopping portion110.

In some optional embodiments of the present disclosure, the restoring force provided by the third restoring member530to the flipping member100is greater than the restoring force provided by the second restoring member15to the press button111, so that the flipping member100can be preferentially restored to the non-triggered position, and then the press button111is restored to the initial position and drives the restricting member12to be restored to the locking position. In this way, the restricting member12can avoid the restoration of the flipping member100, a case where the restricting member12blocks the rotation of the flipping member100towards the non-triggered position during the movement of the restricting member12from the unlocking position to the locking position is avoided, and the restricting member12and the flipping member100are prevented from jamming each other during the movement.

That is to say, when the casing32needs to be opened, the user can first move the restricting member12to the unlocking position, and then operate the flipping member100to move to the door-opening state. When the user releases the flipping member100and the restricting member12at the same time, the flipping member100is preferentially restored to the non-triggered position under the driving of the third restoring member530, so that the restricting member12can be smoothly restored to the locking position after the flipping member100is restored to the non-triggered position, and mutual obstruction of the restricting member12and the flipping member100are prevented during the restoring process.

In some embodiments of the present disclosure, the press button111has a pressing surface310with an insertion hole311. The latching structure10further includes a key which is in insertion fit with the insertion hole311. When the key is engaged with the insertion hole311, rotation of the key drives the press button111to rotate, to drive the restricting member12to rotate.

In some embodiments, when there is a need to switch the restricting member300from the enabled state to the disabled state, the user can drive the press button111to move to the right while inserting the key and then rotate the key in a positive direction to drive the press button111to rotate in a positive direction, so that the press button111drives the restricting member12to move to the right by a certain distance and then rotate in the positive direction. Then, the press button111is operated to move to the left so as to drive the restricting member12to move to the left to be engaged with the second limiting portion202, so that the restricting member12is switched to the disabled state.

When there is a need to switch the restricting member12from the disabled state to the enabled state, in some embodiments, the user can drive the press button111to move to the right while inserting the key and then rotate the key in an opposite direction to drive the press button111to rotate in a positive direction, so that the press button111drives the restricting member12to move to the right by a certain distance and then rotate in the opposite direction. Then, the key is pulled out, the press button111moves to the right to the initial position under the driving of the second recovering member15so as to drive the restricting member12to move to the left to be engaged with the first limiting portion201, so that the restricting member12is switched from the disabled state to the enabled state.

In some other embodiments, the user can drive the press button111to move to the right while inserting the key, so as to drive the restricting member12to move to the right by a certain distance. In this case, the user can release the press button111, the restricting member12can be driven to rotate in the opposite direction under the action of the first restoring member520, and then, under the driving of the second restoring member15, the press button111moves to the right to the initial position, so as to drive the restricting member12to move to the left to be engaged with the first limiting portion201. In this way, the restricting member12is switched from the disabled state to the enabled state.

The cooking device1according to the embodiments of the present disclosure is described below. The cooking device1according to the embodiments of the present disclosure includes a casing32, a door body31, and the latching structure10for the cooking device1according to the above-mentioned embodiments of the present disclosure.

The casing32has a limiting portion21provided thereon. The door body31is connected to the casing32in an openable and closable manner. The door body31has a door hook312provided thereon. The door hook32is engaged with or disengaged from the limiting portion21to close or open the casing32through the door body31.

The latching structure10is the latching structure10of the above-mentioned embodiments of the disclosure. The latching structure10is disposed on the casing32. The flipping member100is engaged with the door hook312. The flipping member100can drive the door hook312to rotate, so as to realize the engagement or disengagement between the door hook312and the limiting portion21.

In some embodiments, as illustrated inFIG.16, the casing32further has a rotating member22provided thereon. An end of the flipping member100is in contact fit with the rotating member22. The door body31is disposed on a front side of the casing32. The door hook312has a rear surface formed in an arc shape and a front surface extending in the up-down direction. When the casing32is closed by the door body31, the door hook312is engaged with the limiting portion21. At this moment, when the user pulls the door body31, the front surface of the door hook312is engaged with the limiting portion21, and the door hook312cannot be disengaged from the limiting portion21.

When the user presses the flipping member100backwards, an end of the flipping member100in contact with the rotating member22rotates upward (in the up-down direction as shown inFIG.11, it should be understood here that the above-mentioned direction is used to describe the drawings, but does not limit the actual setting position and direction of the latching structure10for the cooking device1), to drive the rotating member22to rotate upward. When the rotating member22rotates to a certain position, the rotating member22is brought into contact with the door hook312to drive the door hook312to rotate upward. That is to say, the flipping member100, when rotating, can drive the door hook312to rotate upward through the rotating member22, so that the door hook312is disengaged from the limiting portion21, and the user can pull the door body31to open the casing32, or the user presses the flipping member100and the door body31automatically pops forward to open the casing32.

When the user needs to close the casing32, the door body31can be operated to move backward. At this moment, the rear surface of the door hook312is engaged with the limiting portion21. When the user presses the door body31backward, since the rear surface of the door hook312is formed in an arc shape, the door hook312can rotate upward by the reaction force of the limiting portion21acting thereon. After the door hook312rotates upward by a certain distance and the rear surface of the door hook312is disengaged from the limiting portion21, the door hook312is engaged with the limiting portion21, and at this moment, the casing32can be closed by the door body31.

In some embodiments of the present disclosure, the door body31is rotatably connected to the casing32, and the door body31is rotatable relative to the casing32to open or close the casing32. The door body31and the casing32can be rotatably connected through, but not limited to a hinged manner, as long as the door body31and the casing32can be rotatably connected together. In addition, in some embodiments, the door body31can be connected to the casing32in a non-detachable manner, so that the cooking device1has a good structural integrity, a firm installation, and a beautiful appearance. In some other embodiments, the door body31can be detachably connected to the casing32, so that if a structure in the casing32is damaged, the door body31can be disassembled from the casing32for maintenance.

By using the latching structure10for the cooking device1according to the above-mentioned embodiments of the present disclosure, the cooking device1according to the embodiments of the present disclosure has the advantages of locking the door body31, protecting children from being scalded due to accidental touch, having a relatively simple structure, and facilitating cost reduction.

In some embodiments of the present disclosure, the casing32has a control box2provided thereon. The control box2is configured to control an operation state of the cooking device1. The latching structure10is located on a rear side of the control box2. The user can operate the control box2to operate on the working state of the cooking device1. The latching structure10is disposed on the rear side of the control box2, so as to ensure the overall aesthetics of the cooking device1. In some embodiments of the present disclosure, the casing32has a door-opening button33provided thereon. The door-opening button33is configured to trigger the flipping member100.
