This application provides a dehumidifier.

In the embodiment of this application, please refer toFIGS.1to4, the dehumidifier includes a water tank10, a machine body20and a position limiting structure. The water tank10has an upward mounting opening11, and the machine body20has an idle state in which the machine body20is at least partially housed in the water tank10through the mounting opening11.

The position limiting structure includes a stopper40, which can move into and out of the mounting opening11, and has a first position and a second position. In the first position, the stopper40enters in the mounting opening11and is located on a movement path of the machine body20moving toward inside of the water tank10. In the second position, the stopper40is positioned out of the mounting opening11for the machine body20to be accommodated in the water tank10.

In this embodiment, dehumidification water generated when the machine body20performs dehumidification can enter the water tank10. The machine body20and the water tank10are both square in shape, however those are the shapes of the machine body20and the water tank10in only one embodiment. In other embodiments, the machine body20and the water tank10may be, but are not limited to, circular, polygonal, or even irregular in shape, and the machine body20can be at least partially received within the water tank10through the mounting opening11.

When the machine body20is taken out of the water tank10for dehumidification, the stopper40can be moved to the first position and enter the mounting opening11(the stopper40can be switched to the first position when the machine body20is taken out of the water tank10, or when there is a certain amount of dehumidification water in the water tank10after the machine body20has operated for a certain period of time, or when the machine body20is lifted again after the machine body20has operated for a certain period of time). At this time, the stopper40is located on the movement path of the machine body20moving toward inside of the water tank10, so that when the machine body20moves toward inside of the water tank10, the stopper40can abut against a bottom of the machine body20, and can restrict the machine body20from moving toward inside the water tank10. When the machine body20finishes working and the dehumidification water in the water tank10is discharged or poured out, the stopper40is switched to the second position out of the mounting opening11, so that the machine body20can move toward inside the water tank10and be accommodated in the water tank10.

In the technical scheme of this application, a stopper40capable of movably entering and exiting a mounting opening11is provided at the water tank10, when the stopper40moves to a first position in the mounting opening11, the stopper40can be located on a movement path of the machine body20moving toward inside of the water tank10, so that when the machine body20moves toward inside of the water tank10, the stopper40can abut against a bottom of the machine body20, and can restrict the machine body20from moving toward inside of the water tank10. Therefore, it can avoid the case where the machine body20falls directly into the dehumidification water in the water tank10and is damaged, that is, it can reduce the case where the water tank10has dehumidification water, and the user mistakenly puts the machine body20into the water tank10and causes water damage to the machine body20.

By disposing the water tank10outside the machine body20, a volume of the water tank10is larger, a storage capacity of the water tank10is increased, the number of times a user pours water is reduced, and the weight of the machine body20is also reduced which facilitates the user to carry the machine body20. In addition, when the machine body20is in an idle state, the machine body20is received in the water tank10, the center of gravity of the dehumidifier can be lowered, so that the dehumidifier can be placed stably and is not easy to fall, and an overall occupied space of the dehumidifier is reduced and the user can place the dehumidifier conveniently.

In this embodiment, the machine body20also has a working state, in which the machine body20is raised from the water tank10through the mounting opening11. Specifically, in the working state, the machine body20at least partially protrudes above the water tank10, for example, a portion of the machine body20provided with an air inlet and an air outlet is located above the water tank to be exposed outside the water tank10, which substantially elevates a position of the air outlet of the machine body20, so that the dehumidified air can be blown to a further position, and it is beneficial to improve a range of indoor air flow. Moreover, the dehumidification water generated by the machine body20can naturally fall into the water tank10, and it is convenient for collecting the dehumidification water. Of course, in other embodiments, the machine body20may be disposed entirely outside the water tank10.

In one embodiment, an inner wall of the water tank10is provided with a support protrusion12, and a side of the machine body20is provided with an avoidance recess21. The avoidance recess21extends to the bottom of the machine body20. In the idle state, the support protrusion12extends into the avoidance recess21. In the working state, an upper end of the support protrusion12supports the bottom of the machine body20. Specifically, the water tank10is provided outside the machine body20, the support protrusion12is provided spaced from a bottom wall of the water tank10, and the support protrusion12is provided spaced from an edge of the mounting opening11. That is, the upper end of the support protrusion12is lower than an upper end edge of the water tank10, and the avoidance recess21extends in a height direction (an up and down direction) of the machine body20.

When the dehumidifier is used, the machine body20is rotated until the avoidance recess21is staggered with the supporting protrusion12of the water tank10, so that the bottom of the machine body20abuts against the upper end of the supporting protrusion12, the machine body20is supported by the supporting protrusion12and raised from the water tank10. At this time, the machine body20is in the working state, and the dehumidification water generated during working of the machine body20can be discharged into the water tank10. When the machine body20finishes working and the water is discharged from the water tank10, the machine body20is rotated to a state where the avoidance recess21faces the support protrusion12, so that the support protrusion12extends into the avoidance recess21, and the machine body20is accommodated in the water tank10an stands in the idle state.

Thus, when the upper end of the support projection12supports the bottom of the machine body20, a portion of the machine body20remains within the water tank10. Compared with the way that the machine body20is completely raised from the inside of the water tank10and placed above the water tank10, this arrangement enables the portion of the water tank10above the upper end of the supporting protrusion12to restrict the machine body20, effectively reduces the turnover of the machine body20relative to the water tank10, and greatly improves the stability of the machine body20in the working state. The support protrusion12may be a convex structure integrally formed on an inner wall of the water tank10, or may be a support structure movably mounted on the inner wall of the water tank10(the support structure may refer to a mounting mode of the stopper40). Of course, in other embodiments, the bottom of the machine body20may abut against an upper edge of the water tank10.

In one embodiment, a mounting position is provided below the support protrusion12, and the stopper40is slidably installed at the mounting position. A sliding direction of the stopper40is a transverse direction. At the first position, the stopper40extends toward a lateral side of the support protrusion12to restrict the machine body20from moving toward the water tank10. At the second position, the stopper40is retracted to the mounting position for the machine body20to be accommodated in the water tank10.

In particular, a lateral direction of the support projection12is the transverse direction (i.e., a horizontal direction). The sliding direction of the stopper40may be along a horizontal extension direction of the inner wall of the water tank10. At the first position, a length of the stopper40protruding from the support protrusion12is greater than an engagement gap between the support protrusion12and the avoidance recess21, that is, a total length of the stopper40and the support protrusion12along the horizontal extension direction of the inner wall of the water tank10is greater than a width of the avoidance recess21along the horizontal extension direction of an outer wall of the machine body20. When the user mistakenly places the machine body20in the water tank10in a state where the avoidance recess21faces the support protrusion12, a protruding end of the stopper40can support the bottom of the machine body20, thereby restricting the machine body20from continuously entering the water tank10downward.

At the second position, the stopper40can be retracted to the mounting position, that is, the length of the stopper40protruding relative to the support protrusion12is smaller than the engagement gap between the support protrusion12and the avoidance recess21, or the stopper40is entirely retracted into the mounting position, so as to avoid interference between the stopper40and the machine body20and ensure that the machine body20can smoothly enter the water tank10. Of course, in other embodiments, the sliding direction of the stopper40can be a direction perpendicular to an inner wall surface of the water tank10. In addition, in other embodiments, the stopper40and the support projection12can be laterally spaced apart. Further, in other embodiments, the stopper40can be rotatably mounted on the inner wall of the water tank10to be able to rotate into and out of the mounting opening11.

By providing a support protrusion12on an inner wall of the water tank10, and a position limiting structure at a mounting position below the support protrusion12, a stopper40of the position limiting structure is slidably mounted at the mounting position. When the stopper40slidably protruding toward the lateral side of the support protrusion12, even if the user mistakenly places the machine body20on the water tank10in a state where the avoidance recess21faces the support protrusion12, the stopper40can abut against the bottom of the machine body20, thereby restricting the machine body20from continuing to fall into the water tank10. As such, after the machine body20is taken out from the water tank10, prior to startup of the machine body20, the stopper40can protrude toward the support protrusion12to prevent the machine body20from being put into the water tank10. Even if the user wants to put the machine body20into the water tank10after the dehumidifier has operated for a certain period of time when there is already dehumidification water in the water tank10, the stopper can prevent the machine body20from falling directly into the dehumidification water in the water tank10and being damaged. It reduces the possibility that when the water tank10has dehumidification water, the user mistakenly puts the machine body20into the water tank10and cause water damage to the machine body20.

In one embodiment, the inner wall of the water tank10is provided with a plurality of support protrusions12, and the plurality of support protrusions12are distributed at intervals along a circumferential direction of the water tank10. The outer surface of the machine body20is provided with a plurality of avoidance recesses21, and the plurality of avoidance recesses21are arranged at intervals along a circumferential direction of the machine body20. Specifically, each support protrusion12corresponds to at least one avoidance recess21that is to engage with the support protrusion12, that is, the number of avoidance recesses21can be larger than the number of support protrusions12, and each support protrusion12is engaged with at least one avoidance recess21to ensure that the machine body20can be accommodated in the water tank10.

As is understandable, the plurality of support protrusions12are arranged at intervals in the circumferential direction of the water tank10. When the machine body20needs to be switched from a idle state to the working state, the machine body20can be lifted out of the water tank10, and rotated for a certain angle relative to the water tank10, so that the plurality of avoidance recesses21and the plurality of support protrusions12are dislocated with each other, and the upper end of the support protrusions12can support the portion of the bottom of the machine body20without the avoidance recesses21. As such, the bottom of the machine body20is jointly supported by the plurality of support protrusions12, so that a plurality of positions in the circumferential direction of the machine body20can be supported, and the stability of the machine body20in the working state is improved. When a plurality of support protrusions12are provided, the stopper40or stoppers40may be provided below only one or part of the support protrusions12, or the stoppers40may be provided below each of the support protrusions12.

The plurality of support protrusions12can be evenly arranged along the circumferential direction of the water tank10, so as to ensure that when the bottom of the machine body20abuts against the plurality of support protrusions12, the force applied on the machine body20in the circumferential direction is consistent, which is beneficial to improve the stability of the machine body20in the working state. For example, when the number of the supporting protrusions12is two, the two supporting protrusions12are provided at two opposite sides of the water tank10, or the like. Of course, in other embodiments, when the number of support protrusions12is greater than or equal to three, the plurality of support protrusions12may be non-uniformly arranged along the circumferential direction of the water tank10. In addition, the machine body20may be cylindrical, elliptical or prismatic, and the shape of the water tank10is adapted to the shape of the machine body20. When the machine body20is prismatic, the water tank may be square, regular pentagonal, regular hexagonal, or the like.

In addition, each mounting position can be provided with one or more stoppers40, and the sliding directions of the plurality of stoppers40are in the transverse direction. For example, in an embodiment, each mounting position is provided with two stoppers40, and the two stoppers40slide out of the mounting position in opposite directions. As such, when the stoppers40support the bottom of the machine body20, the machine body20is supported by a plurality of stoppers40together, thereby ensuring the stability of the machine body20and reducing the possibility of inclination of the machine body20.

In order to reduce the user's operation and facilitate the user to use the dehumidifier, please refer toFIGS.4to6. In an embodiment, the position limiting structure further includes a pressing block50. The pressing block50is slidably installed at the water tank10, and a sliding direction of the pressing block50is the up and down direction. A linkage structure is provided between the pressing block50and the stopper40, so that when the pressing block50slides downward, the stopper40slides from the second position to the first position. The pressing block50may be disposed outside the water tank10or inside the water tank10. If the pressing block50is disposed inside the water tank10, an upper end of the pressing block50can protrude outward from the mounting opening11for the user to operate. Alternatively, the pressing block50may be pressed down by the bottom of the machine body20abutting against the upper end of the pressing block50, to drive the stopper40to slide from the second position toward the first position. By providing the pressing block50, the driving of the stopper40can be facilitated, and the operation of the user can be facilitated.

In this embodiment, the pressing block50is slidably mounted at the mounting position. At the second position, the upper end of the pressing block50is higher than the upper end of the support protrusion12. At the first position, the upper end of the pressing block50is not higher than the upper end of the support protrusion12. Specifically, when the machine body20is in the idle state, the stopper40is at the second position. At this time, the stopper40is raised upward through the linkage structure, so that the upper end of the pressing block50is higher than the upper end of the support protrusion12. When the machine body20is switched to the working state, before the bottom of the machine body20is placed on the upper end of the supporting protrusion12, the machine body20first abuts against the upper end of the pressing block50, thereby pressing the pressing block50down until the bottom of the machine body20abuts against the upper end of the supporting protrusion12. During the pressing down of the pressing block50, the pressing block50drives the stopper40through the linkage structure to protrude laterally toward the support projection12and move to the first position. In this way, when the user puts the machine body20in the working state, the stopper40can be automatically switched to the first position, and the user does not need to manually operate the stopper40, thus greatly facilitating the user's use.

After the dehumidifier finishes working, since the stopper40is in the first position, it is needed to retract the stopper40before the machine body20can be put into the water tank10. In one embodiment, the user manually switches the stopper40from the first position to the second position, so that when the user manually operates the stopper40, the user will find whether there is dehumidification water in the water tank10, thereby avoiding the user directly putting the machine body20into the water tank10when the user does not find that there is dehumidification water in the water tank10, resulting in inflow of water and damage to the machine body20. Of course, in other embodiments, it can be the situation of manually driving the stopper40from the mounting position to the first position by the user without providing the pressing block50. Alternatively, a motor can be provided at the mounting position, and the stopper40is driven by the motor to switch between the first position and the second position.

The linkage structure may be one of various of types. For example, in one embodiment, the linkage structure includes a first sliding member provided at the pressing block50and a second sliding member provided at the stopper40. At least one of the first sliding member or the second sliding member extends obliquely upward along the direction in which the stopper40slides out of the mounting position. That is, there may be the first sliding member or the second sliding member extending obliquely upward in the direction in which the stopper40slides out of the mounting position to form a long strip shape. Alternatively, there may be both the first sliding member and the second sliding member extending obliquely upward along the direction in which the stopper40slides out of the mounting position to form long strip shapes.

When the pressing block50moves downward, the second sliding member abuts against the first sliding member and slides relative to the first sliding member (along an extension direction of the first sliding member or the second sliding member), thereby driving the stopper40to move in the direction of sliding out of the mounting position to move to the first position. When the stopper40is switched from the first position to the second position, the first sliding member abuts against the second sliding member and can slide relative to the second sliding member (along the extension direction of the first sliding member or the second sliding member), thereby driving the pressing block50to move upward until the stopper40moves to the second position. As such, the linkage structure is formed between the pressing block50and the stopper40, the structure is simple, and no additional part is needed, the material is reduced, and the assembly efficiency is improved and the cost is reduced. Of course, in other embodiments, the linkage structure may include a link, a first hinge member provide at the stopper40, and a second hinge member provided at the pressing block50, one end of the link is hinged with the first hinge member and the other end of the link is hinged with the second hinge member.

Referring toFIGS.7and8, the structure of the first sliding member may vary. For example, in one embodiment, the first sliding member includes a sliding groove31, which extends obliquely upward along the direction in which the stopper40slides out of the mounting position. The second sliding member includes a sliding protrusion33, and the sliding protrusion33is slidably mounted in the sliding groove31. The sliding groove31is formed at the pressing block50and the sliding protrusion33is provided at the stopper40, so that the sliding protrusion is always located in the sliding groove31. That is, when either of the stopper40and the pressing block50is operated, the other can be linked to move, and the connection reliability between the stopper40and the pressing block50can be ensured.

When two stoppers40are provided at the mounting position (seeFIGS.5and6), the structures of the two stoppers40can be the same, so that the two stoppers40are actually made of the same material, thereby reducing types of materials used and the cost. A sliding groove31is provided at the pressing block50corresponding to each of the stoppers40. In one embodiment, the second sliding member includes two sliding protrusions33, and the two sliding protrusions33are provided at the same side of the stopper40and distributed at intervals in the up and down direction. For ease of illustration, a center line is formed at each stopper40, and the center line extends in the sliding direction of the stopper40and passes through center points between an upper surface and a lower surface of the stopper40.

The positions of the two sliding projections33on the stopper40are symmetrically arranged with the center line as a symmetrical line.

In addition, in one embodiment, the first sliding member has a first surface32facing downward, and the second sliding member has a second surface34facing the first surface32. At least one of the first surface32or the second surface34extends obliquely upwardly in the direction in which the stopper40slides out of the mounting position. The first surface32and the second surface34are in contact with each other and can slide relative to each other when the stopper40is in contact with the pressing block50. Thus, the structure is simple, and structural strengths of the first sliding member and the second sliding member can be guaranteed, which is beneficial to improving the linkage reliability of the stopper40and the pressing block50.

When two stoppers40are arranged at the mounting position, the structures of the two stoppers40can be the same, so that the two stoppers40are actually made of the same material, thereby reducing types of materials used and the cost. In one embodiment, the first sliding member has two first surfaces32facing downward, a distance between the two first surfaces32gradually increases in an upward direction. The second sliding member has two second surfaces34, a distance between the two second surfaces34gradually increases in the direction in which the stopper40slides out of the mounting position. The positions of the two second surfaces34on the stopper40are arranged symmetrically with the center line as the symmetrical line.

In addition, in an embodiment, the first sliding member includes a sliding groove31and a first surface32provided below the sliding groove31, and the second sliding member includes a sliding protrusion33and a second surface34.

Referring toFIGS.1to4, in order to ensure a movement effect of the stopper40and the pressing block50, in one embodiment, the position limiting structure further includes a shield60. The shield60covers the mounting position, and the stopper40and the pressing block50are located between the shield60and the inner wall of the water tank10. Specifically, the shield60is plate shaped and connected to the water tank10, and an upper end of the shield60is not higher than the upper end of the support protrusion12, so that the bottom of the machine body20can abut against the upper end of the support protrusion12. By covering the shield60at the mounting position, the linkage structure between the stopper40and the pressing block50can be prevented from being exposed to outside, and foreign objects can be prevented from touching the linkage structure or sundries can be prevented from entering the linkage structure, thus playing a better protective role on the linkage structure, and ensuring the linkage reliability of the stopper40and the pressing block50. Of course, in other embodiments, the shield60may be in a grid structure or the like, or be omitted.

In one embodiment, a first guide structure is provided between the shield60and the stopper40, and the first guide structure is configured to restrict the stopper40from moving up and down. Specifically, the first guide structure extends along the sliding direction of the stopper40to ensure that the stopper40can slide smoothly between the inner wall of the water tank10and the shield60. Since the first guide structure is disposed between the shield60and the stopper40, there is no need to provide a guide structure on the inner wall of the water tank10, thereby simplifying the structure of the water tank10. Of course, in other embodiments, the first guide structure may be provided between the water tank10and the stopper40.

Referring toFIGS.7and10, the first guide structure may have one of various configurations. For example, in one embodiment, the first guide structure includes a first guide groove61formed at the shield60. The first guide groove61extends in the transverse direction and has a first exiting opening62. The stopper40is slidably mounted in the first guide groove61and can protrude out from the first exiting opening62. Specifically, the first guide groove61extends in the sliding direction of the stopper40, and the first exiting opening62is located at one end of the first guide groove61away from the pressing block50. In one embodiment, the stopper40is wholly and slidably installed in the first guide groove61as a whole, that is, a lower side portion of the stopper40slides relative to a lower side wall of the first sliding groove, and an upper side portion of the stopper40is slidably connected with an upper side wall of the first sliding groove. In this way, a structural strength of the first guide structure is high, and the movement reliability of the stopper40can be guaranteed to be good. Of course, the stopper40may be partially and slidably mounted in the first guide groove61. Of course, this application is not limited to this, the first guide groove61may be formed at the stopper40. The first guide structure includes a protrusion provided at the shield60, and the protrusion can protrude from the first guide groove61.

In addition, in an embodiment, the first guide structure includes a first guide hole41formed at the stopper40and a first guide post63provided at the shield60. The first guide hole41extends in the transverse direction to form a long strip shape, and the first guide post63is slidably installed in the first guide hole41. In particular, the first guide hole41extends in the sliding direction of the stopper40to form a long strip shape, and both ends of the first guide hole41are closed, so that the first guide post63can always be located in the first guide hole41. That is, the stopper40can be guided to slide, and the stopper40can be prevented from being separated from the shield60, so that the overall reliability of the position limiting structure is high. A number of first guide posts63may be one or more. When the number of the first guide posts63is more than one, the plurality of first guide posts63are distributed at intervals in the sliding direction of the stopper40. Of course, this application is not limited to this, the first guide hole41may be formed at the shield60and the first guide post63may be provided at the stopper40. In addition, in one embodiment, the first guide structure may include the first guide groove61, the first guide post63provided in the first guide groove61, and the first guide hole41formed at the stopper40.

Referring toFIGS.5,6and10, in order to facilitate the assembly of the position limiting structure, in one embodiment, the first guide post63is provided with a first limiting protrusion631. The first limiting protrusion631is located at a free end of the first guide post63and protruding toward a lateral direction of the first guide post63. The stopper40is slidably installed between the first limiting protrusion631and the shield60. Specifically, each of two opposite sides of the free end of the first guide post63is provided with one first limiting protrusion631. Two first limiting protrusions631are distributed along a width direction of the first guide hole41. A protrusion height of the first limiting protrusion631relative to a side surface of the first guide post63is greater than a gap between the first guide post63and the first guide hole41, and a distance between the first limiting protrusion631and a root portion of the first guide post63is greater than a depth of the first guide hole41. After the free end of the first guide post63enters from one end of the first guide hole41and existed out from the other end of the first guide hole41, the first limiting protrusion631is also existed out of the first guide hole41and abuts against an edge of the first guide hole41, thereby restricting the first guide post63from being separated from the first guide hole. When assembling the position limiting structure, the stopper40can be installed at the shield60first, and then the shield60and the stopper40can be installed at the inner wall of the water tank10together, and the situation that the stopper40and the shield60are separated from each other during the mounting process can be avoided, thereby facilitating the assembly of the position limiting structure. Of course, in other embodiments, there may be only one first limiting protrusion631provided at the free end of the first guide post63.

Referring toFIGS.6and7, in order to facilitate the first limiting protrusion631to pass through the first guide hole41, in one embodiment, the stopper40is formed with first material reduction holes43, and the first material reduction holes43are arranged at intervals at an outer side of the first guide hole41and extending along an extension direction of the first guide hole41. That is, each first material reduction hole43has a long strip shape. By providing the first material reduction holes43at the outer side of the first guide hole41, the elasticity of the wall of the first guide hole41is increased. When the free end of the first guide post63is engaged in the first guide hole41, the first limiting protrusion631can abut against the wall of the first guide hole41. At this time, the wall of the first guide hole41can be elastically deformed toward the first material reduction holes43, so that an abutting force between the first limiting protrusion631and the wall of the first guide hole41can be reduced, the force required for the assembly can be reduced, and the first limiting protrusion631can be easily passed through the first guide hole41to facilitate assembly of the position limiting structure. The number of the first material reduction holes43may be one or more. When the number of the first material reduction holes43is more than one, the plurality of first material reduction holes43are distributed at intervals along the extension direction of the first guide hole41, so that a length of each first material reduction hole43can be reduced, which ensures that the wall of the first guide hole41has sufficient strength, and prevents the wall of the first guide hole41from being easily deformed or broken and the first limiting protrusion631from easily falling out. Of course, in other embodiments, the first material reduction holes43may be omitted.

In one embodiment, the first guide hole41is provided with a necking portion42. A width of the first guide hole41at the necking portion42is smaller than a size of the first guide post63. At the second position, the first guide post63is located on a side of the necking portion42away from the pressing block50. Specifically, the necking portion42is spaced apart from the ends of the first guide hole41, and a distance between the necking portion42and the first guide hole41is larger than a diameter of the first guide post63, so that the first guide post63can pass over the necking portion42and be located on the side of the necking portion42away from the pressing block50. In this way, when the stopper40is at the second position, the movement of the stopper40toward the first position can be restricted by the necking portion42, thereby avoiding the situation that the machine body20cannot be normally taken out or scratched due to the interference between the stopper40and the machine body20during the process of taking out the machine body20from the water tank10. In one embodiment, the stopper40is provided with a first material reduction hole43corresponding to the necking portion42, so as to reduce the friction between the necking portion42and the first guide post63and reduce abrasion when the first guide post63passes through the necking portion42. A protrusion may be provided at one side wall of the first guide hole41to form the necking portion42, or protrusions may be provided at both side walls of the first guide hole41to form the necking portion42, or when the first material reduction hole43is provided, the side wall of the first guide hole41may be raised inward to form the necking portion42.

Referring toFIGS.7and8, in order to reduce the friction exerted on the stopper40in the sliding process, in one embodiment, the stopper40has at least one first sliding surface, the first sliding surface facing the shield60or the inner wall of the water tank10. The first sliding surface is provided with a first sliding rib44, and the first sliding rib44extends along the sliding direction of the stopper40. It should be noted that, the first sliding surface is a surface of the stopper40that can contact the shield60or the inner wall of the water tank10. By providing the first sliding rib44on the first sliding surface, a contact area between the stopper40and the shield60(or the inner wall of the water tank10) can be reduced by contacting the stopper40with the shield60(or the inner wall of the water tank10) through the first sliding rib44, so that the friction exerted on the stopper40during sliding can be reduced when the stopper slides relative to the shield60(or the inner wall of the water tank10), and the sliding effect can be improved. A cross section of the first sliding rib44may be semicircular, square, or triangular. For example, the cross section of the first sliding rib44is semicircular, there is only linear contact between the first sliding rib44and the shield60(or the inner wall of the water tank10), thereby further reducing friction and friction resistance.

The stopper40may have only one first sliding surface facing the shield60or the inner wall of the water tank10, or may have a plurality of first sliding surfaces. For example, in the embodiment that the stopper40is slidably mounted in the first guide groove61, the stopper40has four first sliding surfaces, one of the four first sliding surfaces faces an upper side wall of the first guide groove61, one of the four first sliding surfaces faces a lower side wall of the first guide groove61, one of the four first sliding surfaces faces a groove bottom wall of the first guide groove61, and one of the four first sliding surfaces faces the inner wall of the water tank10. Each of the first sliding surfaces is provided with a first sliding rib44. Of course, the first sliding rib(s)44may be provided at parts of the first sliding surfaces.

Referring toFIGS.8and10, in one embodiment, a second guide structure is provided between the shield60and the pressing block50, and the second guide structure is configured to restrict the pressing block50from moving in the transverse direction. Specifically, the second guide structure extends along the sliding direction of the pressing block50to ensure that the pressing block50can slide smoothly between the inner wall of the water tank10and the shield60. Since the second guide structure is disposed between the shield60and the pressing block50, there is no need to provide a guide structure on the inner wall of the water tank10, thereby simplifying the structure of the water tank10. Of course, in other embodiments, the second guide structure may be provided between the water tank10and the pressing block50.

The second guide structure may have one of various configurations. For example, in one embodiment, the second guide structure includes a second guide groove64formed at the shield60. The second guide groove64extends in the up and down direction and has a second exiting opening641facing upward. The pressing block50is slidably mounted in the second guide groove64and can protrude out from the second existing opening641. Specifically, the second guide groove64extends in the sliding direction (i.e., the up and down direction) of the pressing block50, the second exiting opening641is located at an upper end of the second guide groove64, and the lower end of the second guide groove64penetrates through an upper groove wall of the first guide groove61. In one embodiment, the pressing block50is wholly and slidably mounted within the second guide groove64. In this way, the structural strength of the second guide structure is high, and the movement reliability of the pressing block50can be ensured to be good. Of course, the pressing block50may be partially and slidably mounted in the second guide groove64. Of course, this application is not limited to this, and the second guide groove64may be formed at the pressing block50. The second guide structure includes a protrusion provided at the shield60, and the protrusion can protrude from the second guide groove64.

In addition, in an embodiment, the second guide structure includes a second guide hole51formed at the pressing block50and a second guide post65provided at the shield60. The second guide hole51extends in the up and down direction to form a long strip shape, and the second guide post65is slidably mounted in the second guide hole51. Specifically, the second guide hole51extends along the sliding direction of the pressing block50to form a long strip shape, and both ends of the second guide hole51are closed, so that the second guide post65can always be located in the second guide hole51. That is, the pressing block50can be guided to slide, and the pressing block50can be prevented from being separated from the shield60, so that the overall reliability of the position limiting structure is high. A number of the second guide posts65may be one or more. When the number of the second guide posts65is more than one, the plurality of second guide posts65are spaced apart in the sliding direction of the pressing block50. Of course, this application is not limited to this, and the second guide hole51may be formed at the shield60and the second guide post65may be provided at the pressing block50. In addition, in one embodiment, the second guide structure may include a second guide groove64, the second guide post65provided in the second guide groove64, and the second guide hole51formed at the stopper40.

In one embodiment, the second guide hole51is arranged from one side of the pressing block50toward a direction close to the other opposite side. That is, the second guide hole51is offset from a midpoint position between the two opposite sides of the pressing block50. The second guide post65is provided at a groove bottom wall of the second guide groove64, and the second guide post65is provided corresponding to the second guide hole51. That is, the second guide post65is also offset from a midpoint position of two groove side walls of the second guide groove64. In this way, it can ensure that both the pressing block50and the shield60have unique installation states, and it can prevent the pressing block50from being installed in reverse. Of course, in other embodiments, the second guide hole51can be provided at the midpoint position of the two opposite sides of the pressing block50.

In order to facilitate the assembly of the position limiting structure, in one embodiment, the second guide post65is provided with a second limiting protrusion651. The second limiting protrusion651is located at a free end of the second guide post65and protrudes toward a lateral direction of the second guide post65. The pressing block50is slidably installed between the second limiting protrusion651and the shield60. Specifically, each of two opposite sides of the free end of the second guide post65is provided with one second limiting protrusion651. Two second limiting projections651are distributed along a width direction of the second guide hole51. A protrusion height of the second limiting protrusion651relative to a side surface of the second guide post65is greater than a gap between the second guide post65and the second guide hole51, and a distance between the second limiting protrusion651and a root portion of the second guide post65is greater than a depth of the second guide hole51. After the free end of the second guide post65enters from one end of the second guide hole51and existed out from the other end of the second guide hole51, the second limiting protrusion651is also existed out of the second guide hole51and abuts against an edge of the second guide hole51, thereby restricting the second guide post65from being separated from the second guide hole. When assembling the position limiting structure, the pressing block50can be installed at the shield60first, and then the shield60and the pressing block50can be installed at the inner wall of the water tank10together, and the situation that the pressing block50and the shield60are separated from each other during the installation process can be avoided, thereby facilitating the assembly of the position limiting structure. Of course, in other embodiments, there may be only one second limiting protrusion651provided at the free end of the second guide post65.

In order to facilitate the second limiting protrusion651to pass through the second guide hole51, in one embodiment, the pressing block50is formed with second material reduction holes52, and the second material reduction holes52are arranged at intervals outside the second guide hole51and extending along an extension direction of the second guide hole51. That is, each second material reduction hole52has a long strip shape. By providing the second material reduction holes52outside the second guide hole51, the elasticity of the wall of the second guide hole51is increased. When the free end of the second guide post65is engaged in the second guide hole51, the second limiting protrusion651can abut against the wall of the second guide hole51. At this time, the wall of the second guide hole51can be elastically deformed toward the second material reduction holes52, so that an abutting force between the second limiting protrusion651and the wall of the second guide hole51can be reduced, the force required for assembly can be reduced, and the second limiting protrusion651can be easily passed through the second guide hole51to facilitate assembly of the position limiting structure. The number of the second material reduction holes52may be one or more. When the number of the second material reduction holes52is more than one, the plurality of second material reduction holes52are distributed at intervals along the extension direction of the second guide hole51, so that a length of each second material reduction holes52can be reduced, which ensures that the wall of the second guide hole51has sufficient strength, and prevents the wall of the second guide hole51from being easily deformed or broken and the second limiting protrusion651from easily falling out. Of course, in other embodiments, the second material reduction holes52may be omitted.

Referring toFIGS.8and9, in order to reduce the friction exerted on the pressing block50in the sliding process, in one embodiment, the pressing block50has at least one second sliding surface, the second sliding surface facing the shield60or the inner wall of the water tank10. The second sliding surface is provided with a second sliding rib53, and the second sliding rib53extends along the sliding direction of the pressing block50. It should be noted that, the second sliding surface is a surface of the pressing block50that can contact the shield60or the inner wall of the water tank10. By providing the second sliding rib53on the second sliding surface, a contact area between the pressing block50and the shield60(or the inner wall of the water tank10) can be reduced by contacting the pressing block50with the shield60(or the inner wall of the water tank10) through the second sliding rib53, so that the friction exerted on the pressing block50during sliding can be reduced when the pressing block50slides relative to the shield60(or the inner wall of the water tank10), and the sliding effect can be improved. A cross-section of the second sliding rib53may be semicircular, square, or triangular. For example, the cross-section of the second sliding rib53is semicircular, there is only linear contact between the second sliding rib53and the shield60(or the inner wall of the water tank10), thereby further reducing friction and frictional resistance.

The pressing block50may have only one second sliding surface facing the shield60or the inner wall of the water tank10, or have a plurality of second sliding surfaces. For example, in the embodiment that the pressing block50is slidably mounted in the second guide groove64, the pressing block50has four second sliding surfaces, one of the four second sliding surfaces faces an upper side wall of the second guide groove64, one of the four second sliding surfaces faces a lower side wall of the second guide groove64, one of the four second sliding surfaces faces a groove bottom wall of the second guide groove64, and one of the four second sliding surfaces faces the inner wall of the water tank10. Each of the second sliding surfaces is provided with a second sliding rib53. Of course, the second sliding rib(s)53may be provided at parts of the second sliding surfaces.

Referring toFIGS.5and6, in an embodiment, a clamping structure is provided between the pressing block50and the shield60. At the first position, the pressing block50is clamped with the shield60. In this way, the stopper40can be restricted from switching from the first position to the second position, that is, the stopper40can be prevented from automatically switching to the second position before the user discharges the dehumidification water in the water tank10.

Referring toFIGS.9to11, the clamping structure can be one of various configurations. For example, in one embodiment, the pressing block50is provided with an elastic buckle54, and a surface of the shield60facing the mounting position is formed with a stop hole66. The stop hole66extends through a surface of the shield60facing away from the mounting position. At the first position, the elastic buckle54is engaged in the stop hole66. That is, the elastic buckle54and the stop hole66constitute the clamping structure, in other words, the clamping structure includes the elastic buckle54and the stop hole66. When the pressing block50is pressed down to drive the stopper40to move to the first position, the elastic buckle54can engage in the stop hole66, thereby restricting the upward movement of the pressing block50. However, when the user needs to switch the stopper40to the second position, the elastic buckle54located in the stop hole66can be pressed to make the elastic buckle54out of the stop hole66. At this time, the pressing block50is no longer restricted by the stop hole66and can move upward, that is, the stopper40can be switched from the first position to the second position. By adopting the clamping structure formed by the elastic buckle54and the stop hole66, it facilitates the operation of the user, and a contact force between the elastic buckle54and the shield60during the movement prior to that the elastic buckle54is engaged in the stop hole66is reduced, so that the abrasion of the elastic buckle54can be reduced, and the service life of the elastic buckle54can be prolonged. Of course, in other embodiments, the elastic buckle54may be provided at the shield60, and the stop hole66may be formed at the pressing block50. Alternatively, each of the shield60and the pressing block50is provided with an elastic buckle54, and the shield60and the pressing block50are engaged with each other by elastic buckles54.

In order to reduce the length of time of the elastic buckle54being pressed, in one embodiment, the surface of the shield60facing the mounting position is provided with an avoidance slot67extending in the up and down direction, and the avoidance slot67is above the stop hole66and spaced from the stop hole66. At the second position, the elastic buckle54is located in the avoidance slot67. Specifically, when the pressing block50moves upward, the elastic buckle54comes out of the stop hole66and passes over a spacing between the stop hole66and the avoidance slot67, and the elastic buckle54then can enter the avoidance slot67. At this time, the elastic buckle54is spaced apart from a groove bottom of the avoidance slot67, that is, when the elastic buckle54is located in the avoidance slot67, the elastic buckle54is in a free state and does not contact the shield60. In this way, permanent deformation of the elastic buckle54caused by being pressed for a long time can be avoided, and the service life of the elastic buckle54can be prolonged. After the elastic buckle54slides out from the avoidance slot67, during the movement before the elastic buckle54engages in the stop hole66, the elastic buckle54is pressed by the shield60and elastically deforms. By extending the avoidance slot67in the up and down direction to form a long strip shape, a distance between the avoidance slot67and the stop hole66can be reduced, thereby reducing a time duration of the elastic buckle54being pressed, and reducing the friction between the elastic buckle54and the shield60when moving from the avoidance slot67to the stop hole66, and facilitating the prolonging of the service life of the elastic buckle54. In one embodiment, a lower side wall of the avoidance slot67is disposed inclined downward to provide guidance for the elastic buckle54to slide to the avoidance slot67.

Referring toFIGS.12and13, in one embodiment, the support protrusion12includes an upper support plate121and a lower support plate122below the upper support plate121and spaced from the upper support plate121, the mounting position is formed between the upper support plate121and the lower support plate122. Both the upper support plate121and the lower support plate122extend transversely. The upper support plate121has a break, and the pressing block50(refer toFIG.4) extends upward from the break. In this way, the pressing block50can be arranged closer to the inner wall of the water tank10, so that an overall protrusion height of the supporting protrusion12and the position limiting structure relative to the inner wall of the water tank10can be reduced, thereby facilitating the reduction of the depth of the avoidance recess21on the machine body20, and increasing an inner space of the machine body20.

The shield60is provided between the upper support plate121and the lower support plate122, and a lower side portion of the shield60can be brought into abutting against an upper plate surface of the lower support plate122, so that the shield60can be supported by the lower support plate122. An upper side portion of the shield60can be brought into abutting against a lower plate surface of the upper support plate121, so that the upper support plate121can be supported by the lower support plate122, and a supporting capacity of the support protrusion12can be improved.

In order to improve a structural strength of the upper support plate121, in one embodiment, the support protrusion12further includes a first reinforcement rib123. The first reinforcement rib123is connected to the lower plate surface of the upper support plate121, and the shield60is provided with an avoidance position corresponding to the first reinforcement rib123. A lower surface of the first reinforcement rib123may be brought into abutting against a surface facing upward at the avoidance position, so that a supporting area between the shield60and the supporting protrusion12can be increased. The first reinforcement ribs123may have one of various configurations, for example, the first reinforcement rib123may have a criss-crossing grid structure, or the first reinforcement rib123may be a vertical rib extending in the up and down direction.

In order to improve the structural strength of the lower support plate122, in one embodiment, the support protrusion12further includes a second reinforcement rib124, and the second reinforcement rib124is connected to the lower support plate122. The second reinforcement rib124may be connected to an upper plate surface of the lower support plate122. In this case, the shield60may also be provided with an avoidance position corresponding to the second reinforcement rib124, and an upper surface of the second reinforcement rib124may be brought into abutting against a surface facing downward at the avoidance position, so that a support area between the shield60and the support protrusion12can be increased. Alternatively, the second reinforcement rib124may be connected to a lower plate surface of the lower support plate122. The second reinforcement rib124may be one of various configurations, for example, the second reinforcement rib124may be a criss-crossing grid structure, or the second reinforcement rib124may be a vertical rib extending in the up and down direction. In one embodiment, the support protrusion12further includes a support rib, an upper end of the support rib is connected to the lower support plate122, a lower end of the support rib extends toward the bottom wall of the water tank10, and the lower end of the support rib is connected to or spaced from the bottom wall of the water tank10.

Referring toFIGS.10,11and13, in an embodiment, the shield60is detachably connected to the support protrusion12to facilitate the assembly of the position limiting structure. In this way, when the pressing block50, the shield60, or the stopper40is damaged or worn, it can be easily replaced. Since the entire water tank10does not need to be replaced, the cost can be reduced. In one embodiment, the shield60is engaged with the support projection12, which is convenient to assemble, and does not need to be screwed, the production efficiency is improved. Specifically, both ends of the shield60along the sliding direction of the stopper40are provided with buckle holes68, and the first reinforcement rib123is provided with a buckle125corresponding to each buckle hole68. The buckle125protruding along the sliding direction of the stopper40. The shield60are engaged with the support protrusion12through the buckle125and the buckle holes68. In one embodiment, the buckle holes68are provided above and below the stopper40to ensure the connection reliability between the shield60and the supporting protrusion12. Of course, in other embodiments, the shield60and the support protrusion12may also be connected by screws or the like.

The foregoing are only preferred embodiments of this application, and do not limit the scope of this application. All equivalent structural changes made within the concept of this application, using the contents of the specification and drawings of this application, or direct/indirect application in other related technical fields are included in the scope of patent protection of this application.
