This invention mainly provides a dehumidifier, which mainly provides an arrangement relationship between a machine body <NUM> and a water tank <NUM>. The machine body <NUM> has a dehumidification function. When the dehumidifier is in a working state, the water tank <NUM> is configured to storage water formed by the machine body <NUM>. When the dehumidifier is in an idle state, the water tank <NUM> is configured to receive the machine body <NUM>. In this way, a volume of the water tank <NUM> is greatly increased, so that the water tank <NUM> may store more water, so that a continuous working time of the dehumidifier is greatly extended, a number of times the user pours water is reduced, which is beneficial to improving the use experience of the user. At the same time, in the idle state, a volume of the dehumidifier may be greatly reduced, and an amount of containers during transportation may be increased, which is beneficial to greatly reducing transportation and storage costs. Based on this, corresponding improvements have been made to an air duct structure, a support method, a form of the water tank <NUM>, a water level switch <NUM>, a form of a lifting handle <NUM>', a coil structure, etc. of the machine body <NUM>.

The following will mainly use embodiments to describe the specific structure of the dehumidifier. Specifically, first an overall and support relationship of the machine body <NUM> and the water tank <NUM> are introduced, then the form of the water tank <NUM>, the coil structure and the water level switch <NUM> are introduced, and then the air duct system and the form of the lifting handle <NUM>' are introduced.

Referring to <FIG>, in some embodiments of this invention, the dehumidifier includes:.

The dehumidifier has a working state and an idle state. In the working state, the receiving cavity <NUM> of the water tank <NUM> is configured to store water formed by dehumidification of the machine body <NUM>. In the idle state, at least part of the machine body <NUM> is received in the receiving cavity <NUM>.

Specifically, in this embodiment, the machine body <NUM> has a dehumidification function, that is, the machine body <NUM> may remove moisture in the air. There are many ways of dehumidification, such as condensation dehumidification, that is, air is cooled under normal pressure below the dew point temperature to condense water vapor into condensed water; compressed dehumidification, for example, air is compressed and then cooled to condense water vapor in the air into water; adsorption dehumidification, which may be achieved by solid adsorption dehumidification or liquid adsorption dehumidification. In the following embodiments of this application, a refrigerant circulation system formed by a combination of a compressor <NUM>, an evaporator <NUM>, a condenser <NUM>, a throttling device, etc. is used as an example to cool and dehumidify air. An overall shape of the machine body <NUM> may be many, such as a cuboid, a cube, a cylinder, etc. Taking a square-like or round-like cross section as an example. An overall shape of the receiving cavity <NUM> of the water tank <NUM> is similar to the overall shape of the machine body <NUM>, so that the machine body <NUM> may be received while saving space.

When the dehumidifier is working, the machine body <NUM> may be arranged directly above the water tank <NUM>, so that the generated condensate water may flow into the water tank <NUM> under the action of gravity. In addition, as the water in the water tank <NUM> increases, the stability of the dehumidifier in the working state gradually increases. In some embodiments, in the working state, the water tank <NUM> may also be arranged directly above the machine body <NUM>, or the water tank <NUM> and the machine body <NUM> may be arranged in parallel. In this case, a water pump needs to be mounted to pump the water in the machine body <NUM> into the above water tank <NUM>. In the working state, the entire water tank <NUM> may be configured to store water, so that the volume of the water tank <NUM> may be greatly increased, which is beneficial to reducing the number of times the user pours water. It is worth noting that parallel refers to roughly parallel, allowing small deviations.

When the dehumidifier is in the idle state, part or all of the machine body <NUM> is received in the receiving cavity <NUM> of the water tank <NUM>. There are many ways to receive the machine body <NUM>, such as placing the water tank <NUM> with an opening facing upward, and the machine body <NUM> is entered into and taken out from the receiving cavity <NUM> through the opening in up and down directions. Specifically, the opening of the water tank <NUM> is upward, and the machine body <NUM> is entered into and exited from the water tank <NUM> through the opening. In some embodiments, the machine body <NUM> may also be placed on the ground, and the water tank <NUM> may be turned upside down, and then cover an outside of the machine body <NUM>. Either way, the volume of the dehumidifier in the idle state is greatly reduced, so that the amount of containers may be increased during storage and transportation, which is beneficial to greatly saving transportation and storage costs.

In order to further better load the machine body <NUM> in the water tank <NUM>, the overall shape and size of the machine body <NUM> match the shape and size of the receiving cavity <NUM>. A height of the machine body <NUM> matches a height of the receiving cavity <NUM>. For example, the overall shape of the machine body <NUM> is cylindrical, and the overall shape of the receiving cavity <NUM> is also a cylindrical space.

Regarding the specific structure of the machine body <NUM>, the machine body <NUM> includes a case <NUM>, and the case <NUM> defines an air inlet <NUM>, an air outlet <NUM>, and an air duct communicating the air inlet <NUM> and the air outlet <NUM>. An air duct assembly and a heat exchanger assembly are provided inside the air duct. There are many positions where the air inlet <NUM> and the air outlet <NUM> may be defined. For example, the air inlet <NUM> may be defined on a peripheral side (front, rear, left, right) or a top of the case <NUM>, and the air outlet <NUM> may be defined on the peripheral side (front, rear, left, right) or the top of the case <NUM>. Taking the air inlet <NUM> being defined on the peripheral side of the case <NUM>, and the air outlet <NUM> being defined on the top of the case <NUM> as an example. In some embodiments, in order to prevent external dust, insects, mice, etc. from affecting the operation of the dehumidifier, a filter screen may be provided at the positions of the air inlet <NUM> and the air outlet <NUM>. In some embodiments, several meshes may be directly formed on the case <NUM> to replace the filter screen.

In this embodiment, the dehumidifier is divided into two parts: the machine body <NUM> and the water tank <NUM>, and the machine body <NUM> has an independent dehumidification function, which may collect water vapor in the air. In the working state, the machine body <NUM> is arranged above the entire water tank <NUM>, so that the entire water tank <NUM> may be configured for storing water. In this way, the volume and utilization of the water tank <NUM> may be greatly increased, so that the continuous working time of the dehumidifier may be greatly extended, and the number of times the user pours water is reduced, which is beneficial to improving the use experience of the user. At the same time, in the idle state, the machine body <NUM> may be at least partially received in the receiving cavity <NUM>, the volume of the dehumidifier in the idle state is greatly reduced, so that the amount of containers may be increased during storage and transportation, which is beneficial to greatly saving transportation and storage costs.

In some embodiments, in order to ensure that the machine body <NUM> may be stably arranged on a top of the water tank <NUM> in the working state, the top of the water tank <NUM> is provided with a support structure. In the working state, the machine body <NUM> is arranged on the support structure. The support structure may be a structure that is fixedly connected to the water tank <NUM>, or may be a structure that is movably connected to the water tank <NUM>. If the support structure is a structure that is fixedly connected to the water tank <NUM>, in order to maximize the utilization of the space, it is necessary to provide an avoidance position corresponding to the support structure on an outer side wall of the machine body <NUM>, so that the machine body <NUM> may be smoothly placed in the water tank <NUM> after adjusting a certain angle. If the support structure is a structure that is movably connected to the water tank <NUM>, it may be realized that in the working state, the support structure may extend into the receiving cavity <NUM> to support the machine body <NUM>, and in the idle state, the support structure may exit the receiving cavity <NUM>, so that the machine body <NUM> may be unobstructedly received in the water tank <NUM>. Specifically, the support structure may be movably provided on the water tank <NUM>, so that the support structure may extend into the receiving cavity <NUM> in the working state, and drawn out of the receiving cavity <NUM> in the idle state.

In some embodiments, in order to further improve the installation stability of the machine body <NUM> in the working state, the support structure is provided on an inner side wall of the receiving cavity <NUM>, and a top of the support structure is lower than an edge of the opening of the water tank <NUM>. In this way, when the machine body <NUM> is supported by the support structure, a part of the machine body <NUM> is located in the water tank <NUM>, so that while the center of gravity moves down, the machine body <NUM> may be more limited by the inner side wall of the water tank <NUM>, which may further improve the stability of the dehumidifier.

Some specific support methods are described as follows.

The support structure is provided on the water tank <NUM>.

Referring to <FIG>, the support structure is fixedly provided on the water tank <NUM>.

The water tank <NUM> defines a receiving cavity <NUM>, and an inner side wall of the receiving cavity <NUM> is provided with a support boss <NUM>. The dehumidifier has a working state, and a bottom of the machine body <NUM> is abutted against the support boss <NUM> in the working state. The support boss <NUM> may have many shapes, such as square, arc, round, etc. Taking the shape similar to the inner side wall of the receiving cavity <NUM> as an example. For example, when the inner side wall is flat, a cross section of the support boss <NUM> may be rectangular, and when the inner side wall is curved, the cross section of the support boss <NUM> may be curved. In this way, the utilization rate of the support boss <NUM> may be improved as much as possible, and a contact area between the bottom of the machine body <NUM> and the support boss <NUM> may be increased. Taking a support surface of the support boss <NUM> being a flat surface as an example.

In this embodiment, a dehumidifier is divided into two parts: a machine body <NUM> and a water tank <NUM>, and the machine body <NUM> has an independent dehumidification function, which may collect water vapor in the air. And, a support boss <NUM> is provided on an inner side wall of the water tank <NUM>, so that a bottom of the machine body <NUM> may be abutted against the support boss <NUM> in the working state, so as to achieve cooperation of the machine body <NUM> and the water tank <NUM>. At the same time, the machine body <NUM> is arranged above the entire water tank <NUM>, so that the entire water tank <NUM> may be configured for storing water. In this way, the volume and utilization of the water tank <NUM> may be greatly increased, so that the continuous working time of the dehumidifier may be greatly extended, and the number of times the user pours water is reduced, which is beneficial to improving the user experience.

In some embodiments, in order to realize that the machine body <NUM> is received in the water tank <NUM>, the machine body <NUM> defines an avoidance slot <NUM> on an outer side wall corresponding to the support boss <NUM>. The dehumidifier has an idle state, and the support boss <NUM> is received in the avoidance slot <NUM> in the idle state to receive at least part of the machine body <NUM> in the receiving cavity <NUM>. The avoidance slot <NUM> is staggered with the support boss <NUM> in the working state. By defining the avoidance slot <NUM> on the outer side wall of the machine body <NUM>, when the avoidance slot <NUM> and the support boss <NUM> are provided correspondingly, the machine body <NUM> may be received in the receiving cavity <NUM>. When the avoidance slot <NUM> is staggered with the support boss <NUM>, the bottom of the machine body <NUM> may be supported by the support boss <NUM>. There are many ways of staggered configuration, which are related to the specific shapes of the machine body <NUM> and the water tank <NUM>. When the water tank <NUM> and the machine body <NUM> are both arranged in a rectangular shape, the two support bosses <NUM> can be arranged in an asymmetrical structure (the two support bosses <NUM> are provided on two opposite or adjacent side walls), and staggered configuration of the avoidance slot <NUM> and the support boss <NUM> may be realized by adjusting the machine body <NUM> by <NUM>°. When the water tank <NUM> and the machine body <NUM> are square, the staggered configuration of the avoidance slot <NUM> and the support boss <NUM> may be realized by adjusting the machine body <NUM> by <NUM>°. When the cross-sections of the water tank <NUM> and the machine body <NUM> are both similar to circular, there are many rotation angles to achieve staggered configuration, as long as the avoidance slot <NUM> does not correspond to the support boss <NUM>.

In some embodiments, in order to improve the smoothness and reliability of the machine body <NUM> entering the water tank <NUM>, the support boss <NUM> is vertically provided along a height direction of the water tank <NUM>, and the avoidance slot <NUM> is vertically provided along a height direction of an outer side wall of the machine body <NUM>. By providing the support boss <NUM> and the avoidance slot <NUM> vertically, the machine body <NUM> may be straight up and down when entering the water tank <NUM>, which is beneficial to the convenient movement of the machine body <NUM>. At the same time, the avoidance slot <NUM> also plays a guiding role during a moving process of the machine body <NUM>, and the support boss <NUM> plays a role as a guide post, so that the machine body <NUM> may accurately fall into a preset position in the water tank <NUM> along the support boss <NUM>.

In some embodiments, in order to facilitate the transportation of the water tank <NUM> and save material, the outer side wall of the water tank <NUM> defines a slot corresponding to the support boss <NUM>. The slot may be configured as a hand grip slot <NUM> of the water tank <NUM> to facilitate the transportation of the water tank <NUM>. At the same time, the arrangement of the slot reduces the amount of materials used to manufacture the water tank <NUM>, thereby reducing the manufacturing cost of the water tank <NUM>. The hand grip slot <NUM> may have many forms, such as defining through a later process, or directly integral injection molding. In some embodiments, the slot is formed by a side wall of the water tank <NUM> protruding into the water tank <NUM>, and a protruding part forms the support boss <NUM>. In this way, while simplifying the process, the materials used are reduced, and material costs and process costs are saved.

In some embodiments, in order to improve the stability of the support of the machine body <NUM>, a number of the support boss <NUM> is two, and two said support bosses <NUM> are provided on two opposite side walls of the water tank <NUM>. A number of the avoidance slot <NUM> is two, and two said avoidance slots <NUM> are formed on two opposite side walls of the machine body <NUM>. By providing the support bosses <NUM> on the two opposite side walls of the water tank <NUM>, opposite sides of the machine body <NUM> are supported, which is beneficial to improving the stability of the machine body <NUM>.

In some embodiments, in order to further improve the installation stability of the machine body <NUM>, a top of the support boss <NUM> is lower than an edge of the opening of the water tank <NUM>. In this way, a part of the bottom of the machine body <NUM> is located in the receiving cavity <NUM>, so that the machine body <NUM> is more restricted by the side wall of the receiving cavity <NUM>. In addition, it is also beneficial to lowering the overall center of gravity of the dehumidifier, thereby improving the overall stability of the dehumidifier.

Referring to <FIG>, the support structure is movably connected to the water tank <NUM>.

The dehumidifier includes a support <NUM> that is movably connected to the water tank <NUM>. The dehumidifier has a working state and an idle state. In the working state, the support <NUM> is extended into the receiving cavity <NUM> to support the machine body <NUM>. In the idle state, the support <NUM> is drawn out from the receiving cavity <NUM> so that the machine body <NUM> may be at least partially received in the receiving cavity <NUM>.

Specifically, in this embodiment, the support <NUM> may have many forms, such as a rod shape, a block shape, and so on. There are many ways for the support <NUM> to be movably connected to the water tank <NUM>, such as moving relative to the water tank <NUM>, rotating relative to the water tank <NUM>, and so on. That is to say, the support <NUM> realizes the two actions of extending into the receiving cavity <NUM> and exiting the receiving cavity <NUM> by rotating or moving. When the support <NUM> is rotated relative to the water tank <NUM>, a position of a rotational connection may be on the side wall of the water tank <NUM>.

In this embodiment, a dehumidifier is divided into two parts: a machine body <NUM> and a water tank <NUM>, and the machine body <NUM> has an independent dehumidification function, which may collect water vapor in the air. And, a support <NUM> is provided on a side wall of the water tank <NUM>, so that the support <NUM> may be extended into the receiving cavity <NUM> and a bottom of the machine body <NUM> may be abutted against the support boss <NUM> in the working state, so as to achieve cooperation of the machine body <NUM> and the water tank <NUM>. At the same time, the machine body <NUM> is arranged above the entire water tank <NUM>, so that the entire water tank <NUM> may be configured for storing water. In this way, the volume and utilization of the water tank <NUM> may be greatly increased, so that the continuous working time of the dehumidifier may be greatly extended, and the number of times the user pours water is reduced, which is beneficial to improving the use experience of the user. In the idle state, the support <NUM> may be drawn out from the receiving cavity <NUM>, and the machine body <NUM> may be at least partially received in the water tank <NUM>. The volume of the dehumidifier after assembly is greatly reduced, so that the amount of containers may be increased during storage and transportation, which is beneficial to greatly saving transportation and storage costs.

The following takes the support <NUM> moving relative to the water tank <NUM> as an example for description. In some embodiments, the inner side wall of the receiving cavity <NUM> defines a drawing opening, and the support <NUM> is mounted in the drawing opening in a push and pull manner. By defining the drawing opening, the support <NUM> may enter and exit the receiving cavity <NUM> through the drawing opening. When the machine body <NUM> needs to be supported, the support <NUM> may be pushed into the receiving cavity <NUM>. When the machine body <NUM> needs to be received in the water tank <NUM>, the support <NUM> may be drawn out from the receiving cavity <NUM>, which is easy to operate.

Specifically, the support <NUM> includes a support part <NUM>, a handle part <NUM>, and a connection arm <NUM> connecting the support part <NUM> and the handle part <NUM>. The handle part <NUM> is located outside the water tank <NUM>. The support part <NUM> is located in the receiving cavity <NUM> in the working state, and exits the receiving cavity <NUM> in the idle state. The support part <NUM> is configured to support the machine body <NUM>. The handle part <NUM> is configured for the operator to hold. The support part <NUM> is connected to the handle part <NUM> through the connection arm <NUM>, and the handle part <NUM> may control a position of the support part <NUM> through the connection arm <NUM>. When the support <NUM> is drawn out, the operator may use the support <NUM> as a handle to carry the water tank <NUM> or the dehumidifier in the idle state. In this way, the utilization rate of the support <NUM> is improved.

In order to make the movement of the machine body <NUM> in the water tank <NUM> completely unaffected by the support <NUM>, a length of the support part <NUM> is greater than a width of the connection arm <NUM>. The drawing opening is a stepped opening, and one end of the drawing opening with a larger size is close to the receiving cavity <NUM> and may receive the support part <NUM>. That is, a length of the end of the drawing opening with a larger size is greater than or equal to the length of the support part <NUM>. When the support part <NUM> exits the receiving cavity <NUM>, it is received in the drawing opening, so that the support part <NUM> does not protrude from the inner side wall of the receiving cavity <NUM>. In this way, the support part <NUM> does not interfere with the movement of the machine body <NUM> in the water tank <NUM> at all.

In order to prevent the support <NUM> from being separated from the water tank <NUM>, the length of the support part <NUM> is greater than a length of an end of the drawing opening with a smaller size. In this way, the support part <NUM> cannot be separated from the water tank <NUM> through the drawing opening, that is, the support <NUM> is always connected with the water tank <NUM> no matter in the working state or in the idle state. In this way, the support <NUM> is prevented from being lost.

In order to prevent the support <NUM> from falling into the receiving cavity <NUM>, a width of the handle part <NUM> is larger than a width of the end of the drawing opening with a smaller size, and/or, a length of the handle part <NUM> is larger than a length of the end of the drawing opening with a smaller size. In this way, through the limitation of the sizes, the handle part <NUM> cannot enter the drawing opening, so that the operator may easily grasp the handle part <NUM> at any time, which is convenient for the operator to operate.

In some embodiments, in order to improve the operating comfort of the operator, a side of the handle part <NUM> facing away from the outer side wall of the water tank <NUM> defines a handle arc surface. The operator will not be scratched by edges and corners when grasping the handle part <NUM> through the handle arc surface, and at the same time, a contact area between the handle part <NUM> and the hand is increased, which is beneficial for the operator to hold the handle part <NUM> more stably and reliably.

When the water tank <NUM> filled with water or the dehumidifier loaded with the machine body <NUM> is transported through the handle part <NUM>, the load borne by the handle part <NUM> is relatively large, and the relatively large load is finally transferred to the water tank <NUM>. In order to improve the load-bearing strength of the water tank <NUM>, the dehumidifier further includes a reinforcement plate <NUM>. The reinforcement plate <NUM> is provided at a position corresponding to the drawing opening, and the drawing opening is penetrated through the reinforcement plate <NUM> and the side wall of the water tank <NUM>. By providing the reinforcement plate <NUM>, the carrying capacity around the drawing opening is increased, thereby increasing the carrying capacity of the water tank <NUM>, which is beneficial to improving the reliability of the dehumidifier.

In order to ensure the water holding space of the water tank <NUM> as much as possible, the support <NUM> is provided on an upper part of the water tank <NUM>. In this way, both a middle and a lower part of the water tank <NUM> may be configured to hold water, which is beneficial to ensuring an effective water holding space of the water tank <NUM>. In order to improve reliability, a number of the support <NUM> is two, which are provided on two opposite side walls of the water tank <NUM>.

Referring to <FIG>, regarding the form of the water tank <NUM>.

The machine body <NUM> has a dehumidification function, and the overall shape of the machine body <NUM> is cylindrical-like. The water tank <NUM> defines a receiving cavity <NUM>, and the water tank <NUM> is cylindrical-like. The dehumidifier has an idle state, and in the idle state, the machine body <NUM> is at least partially received in the water tank <NUM>.

Specifically, in this embodiment, the overall shape of the machine body <NUM> is cylindrical-like, which means that the overall shape is similar to a cylinder, and according to the requirements of process and installation, protrusions or depressions are formed on an outer surface of the cylinder. In the same way, the water tank <NUM> is cylindrical-like, which means that the overall shape of the water tank <NUM> is similar to a cylinder, and according to the requirements of the process and installation cooperation, protrusions or recesses are formed on a surface or an inner side wall.

In this embodiment, by providing the overall shape of the machine body <NUM> to be cylindrical-like, and the overall shape of the water tank <NUM> to be cylindrical-like, when the machine body <NUM> is received in the water tank <NUM>, compared to the shape with sharp corners, there is no strict directionality, which facilitates the placement of the machine body <NUM> in the water tank <NUM>, which is beneficial to improving the efficiency of the cooperation between the machine body <NUM> and the water tank <NUM>.

In order to reliably support the machine body <NUM>, the inner side wall of the receiving cavity <NUM> has a support boss <NUM>. The dehumidifier has a working state, and a bottom of the machine body <NUM> is abutted against the support boss <NUM> in the working state. The machine body <NUM> defines an avoidance slot <NUM> on an outer side wall corresponding to the support boss <NUM>. The dehumidifier has an idle state, and the support boss <NUM> is received in the avoidance slot <NUM> in the idle state to at least partially receive the machine body <NUM> in the receiving cavity <NUM>. The avoidance slot <NUM> is staggered with the support boss <NUM> in the working state.

In some embodiments, in order to improve the utilization of the support boss <NUM>, the support boss <NUM> is provided in an arc shape along the inner side wall of the receiving cavity <NUM> in its width direction. In this way, the bottom of the machine body <NUM> may be abutted against as many support bosses <NUM> as possible.

In some embodiments, in order to further improve the support stability of the machine body <NUM>, a number of the support boss <NUM> is at least two, and the at least two support bosses are provided circumferentially along the inner side wall of the receiving cavity <NUM> at intervals. A number of the avoidance slot <NUM> is two, the two avoidance slots <NUM> are arranged corresponding to the at least two support bosses <NUM> on the outer side wall of the machine body <NUM> at intervals.

It is worth noting that as the volume of the water tank <NUM> increases, when there is more water stored in the water tank <NUM>, the water tank <NUM> is too heavy to carry for pouring water. At this time, in order to facilitate the user to pour water, a drainage hole <NUM> is defined at a lower part or a bottom of the water tank <NUM>. By providing the drainage hole <NUM>, water in the water tank <NUM> may be drained through the drainage hole <NUM>, without requiring the user to lift the water tank <NUM> to pour water, which is beneficial to the use of the user.

The dehumidifier includes a protective element which is provided on an upper part of the inner side wall of the water tank <NUM>, and/or, a lower part of an outer side wall of the machine body <NUM>. The dehumidifier has an idle state, and in the idle state, the machine body <NUM> may be at least partially received in the water tank <NUM> through an opening.

Specifically, in this embodiment, a shape of the protective element may be many, such as a sheet shape, a strip shape, or a block shape. The protective element may also be made of many materials, such as elastic materials, such as rubber, elastic plastic, etc., or flexible materials, such as cotton wool fabrics. The protective element is mainly configured to isolate the outer side wall of the machine body <NUM> and the inner side wall of the water tank <NUM> to prevent the outer side wall of the machine body <NUM> from being scratched. Therefore, the protective element may be provided on the outer side wall of the machine body <NUM>, or on the inner side wall of the receiving cavity <NUM>.

In this embodiment, by providing the protective element, when the machine body <NUM> is loaded in the water tank <NUM>, the protective element is isolated between the outer side wall of the machine body <NUM> and the inner side wall of the water tank <NUM>, thereby avoiding direct contact and friction between the outer side wall of the machine body <NUM> and the inner side wall of the water tank <NUM>, thereby protecting the outer side wall of the machine body <NUM> and avoiding the outer side wall of the machine body <NUM> from being scratched.

In some embodiments, in order to further improve the utilization of the protective element, a top of the protective element is flush with a top of the opening side of the water tank <NUM>; or, a bottom of the protective element is flush with the bottom of the machine body <NUM>.

In this embodiment, by providing the protective element at the opening of the water tank <NUM> or at the bottom of the machine body <NUM>, the protective element may always act as an isolation beginning from the machine body <NUM> and the water tank <NUM> first come into contact until the machine body <NUM> completely enters into the water tank <NUM>. In this way, the utilization rate of the protective element is improved.

There are many ways to connect the protective element to the inner side wall of the water tank <NUM> or the outer side wall of the machine body <NUM>, and the protective element may be bonded to the inner side wall of the water tank <NUM> or the outer side wall of the machine body <NUM>. In some embodiments, the inner side wall of the water tank <NUM> or the outer side wall of the machine body <NUM> defines a snapped slot, and the protection member is snapped in the snapped slot. An outer side of the protective element is protruded from the outer side wall of the machine body <NUM> or the inner side wall of the water tank <NUM>.

Taking the protective element including a protective strip as an example. The protective strip is extended along a circumference of the water tank <NUM> or extended along a circumference of the machine body <NUM>. That is, the protective element is provided around the inner side wall of the water tank <NUM> or provided around the outer side wall of the machine body <NUM>. The protective strip may be a continuous long strip or short intermittent strips. In this way, a periphery of the machine body <NUM> will not be scratched due to the cooperation with the water tank <NUM>, which is beneficial to maintaining the appearance of the outer side wall of the machine body <NUM>.

Referring to <FIG>, regarding the coil structure.

The outer side of the machine body <NUM> defines a storage slot <NUM> recessed into an interior of the machine body <NUM> for receiving a power cord of the dehumidifier. Specifically, in this embodiment, the storage slot <NUM> may have many shapes, such as a cuboid shape, a cylindrical shape, etc., and its shape may be adapted to the overall shape of the machine body <NUM>. When a side surface defining the storage slot <NUM> is a flat surface, the storage slot <NUM> may have a cuboid shape, and when the side surface defining the storage slot <NUM> is a cylindrical surface, the storage slot <NUM> may be cylindrical. By defining the storage slot <NUM>, the power cord may be completely received in the storage slot <NUM>.

In this embodiment, the outer side of the machine body <NUM> defines a storage slot <NUM> recessed into an interior of the machine body <NUM> for receiving the power cord of the dehumidifier. In the idle state, the power cord of the dehumidifier is received in the storage slot <NUM> so that the power cord does not protrude from a peripheral side of the machine body <NUM>, so that the machine body <NUM> may be easily and quickly received into the water tank <NUM>.

In some embodiments, in order to further ensure that the power cord may be stably stored in the storage slot <NUM>, the dehumidifier further includes a strap. In the idle state, the power cord is tied by the strap and is stored in the storage slot <NUM>. There may be many types of straps. Taking flexible ribbons as examples, such as rubber bands, cable ties, and so on.

To further ensure that the power cord may be stably stored in the storage slot <NUM>, structural components may be provided in the storage slot <NUM>.

Specifically, the dehumidifier further includes a coil storage column <NUM> and a limit stopper <NUM>. One end of the coil storage column <NUM> is fixedly connected to a side wall of the storage slot <NUM>, and the other end of the coil storage column <NUM> is fixedly connected to the limit stopper <NUM>. The limit stopper <NUM> does not protrude from a slot opening of the storage slot <NUM>. In this way, the power cord may be coiled on the coil storage column <NUM>, and the power cord coiled on the coil storage column <NUM> is stopped by the limit stopper <NUM>, and will not detach and exceed the limit stopper <NUM>, that is, the power cord coiled on the coil storage column <NUM> will not protrude from the outer surface of the machine body <NUM>. In this way, the storage condition of the power cord in the idle state may be effectively guaranteed.

In some embodiments, in order to coil the power cord more conveniently, a slot wall connected to the coil storage column <NUM> is provided opposite to the slot opening. In this way, the operator may watch the coiling position, and the operable space is very large, which is convenient for the user's operation.

In some embodiments, in order to standardize the wiring of the power cord and prevent the power cord from protruding from the surface of the machine body <NUM>, a cable trough <NUM> is defined on the surface of the machine body <NUM> adjacent to the storage slot <NUM> to limit a direction of the power cord. The power cord may be arranged in the cable trough <NUM>, and a slot depth of the cable trough <NUM> is greater than a diameter of the power cord, so that the power cord may be received in the cable trough <NUM>.

In order to make the power cord go out from the storage slot <NUM> more smoothly and reliably, the cable trough <NUM> may be communicated with the storage slot <NUM>. In this way, the power cord may directly enter the cable trough <NUM> from the storage slot <NUM> without protruding from the outer surface of the machine body <NUM> in the middle.

In order to further improve the reliability of the power cord in the wiring, the outer side wall of the machine body <NUM> is provided with a retaining rib <NUM>, and the retaining rib <NUM> and the cable trough <NUM> are enclosed to define a limit trough that limits a position of the power cord. The retaining rib <NUM> is disposed on a side wall of the cable trough <NUM>, and an outer surface of the retaining rib <NUM> is flush with the outer side wall of the machine body <NUM>. In this way, when the power cord is in the cable trough <NUM>, it will not be separated from the cable trough <NUM> under the action of gravity or a slight external force, so that the wiring of the power cord is very reliable, which is beneficial to improving the stability of the dehumidifier.

In some embodiments, in order to protect a power plug from being damaged in the idle state, a slot wall of the storage slot <NUM> further defines a plug storage hole <NUM> for mounting the power plug. The storage hole <NUM> may have a variety of forms. It is possible to store plugs of different models and countries through the arrangement.

Referring to <FIG>, regarding water level detection.

There are many ways to detect the water level, which may be wireless detection (such as ultrasonic detection, capacitance detection), or physical detection (floating ball detection). Specific examples are given below for description.

Ultrasonic wireless detection: the dehumidifier includes an ultrasonic water level detection device configured to detect a water level in the water tank <NUM>, and the ultrasonic water level detection device is electrically connected to an electric control main board of the dehumidifier, and a main control circuit is provided on the electric control main board. The ultrasonic water level detection device sends detected water level information in the water tank <NUM> to the electronic control main board, and the electronic control main board judges a current water level. When a preset water level is not reached, a detection result is ignored, and when the preset water level is reached, dehumidification is stopped to avoid the water continues to increase and overflow the water tank <NUM>, causing immeasurable consequences.

In some embodiments, the dehumidifier further includes an alarm device, and the alarm device is electrically connected to the electronic control main board and/or the ultrasonic water level detection device. When the water level is about to reach the preset water level, or has reached the preset water level, the electronic control main board controls the alarm device to give an alarm to remind the user that the current water level needs to be dealt with in time. In some embodiments, the alarm device may be directly electrically connected to the ultrasonic water level detection device. In this way, the alarm device may directly send an alarm based on the detection result of the water level detection device.

In order to detect the water level in the water tank <NUM> conveniently and safely, the machine body <NUM> may be located directly above the water tank <NUM>, and the ultrasonic water level detection device may be arranged at the bottom of the machine body <NUM>. The dehumidifier further includes a display device <NUM>, and the ultrasonic water level detection device is electrically connected to the display device <NUM>. The setting of the display device <NUM> facilitates the user to intuitively monitor the working condition of the dehumidifier, and the current water level in the water tank <NUM> may also be observed from the display device <NUM>. There are many positions where the display device <NUM> may be arranged, taking the display device <NUM> arranged on the top of the machine body <NUM> as an example. In some embodiments, the display device <NUM> may also be arranged on a front side of the machine body <NUM>.

Physical detection by water level switch <NUM>: the dehumidifier includes a water level switch <NUM>, the water level switch <NUM> is arranged at the bottom of the machine body <NUM>, and the water level switch <NUM> includes a float <NUM>. The dehumidifier has an idle state, and in the idle state, at least part of the machine body <NUM> is received in the receiving cavity <NUM>. The bottom of the machine body <NUM> defines a receiving slot <NUM> recessed into the machine body <NUM>. The float <NUM> is movably connected to the machine body <NUM>, and the float <NUM> may be completely received in the receiving slot <NUM> in the idle state.

Specifically, in this embodiment, the water level switch <NUM> is configured to detect the water level in the water tank <NUM>, and the water level switch <NUM> includes a float <NUM>. When the water level switch <NUM> detects the water level, the float <NUM> is in contact with the liquid surface, or is suspended. When the liquid level reaches a certain level and is in contact with the float <NUM>, it supports the float <NUM>. As the liquid level rises, a position of the float <NUM> changes, and the water level is determined according to a change in a height of the float <NUM>. What changes with the position of the float <NUM> may be a capacitance or a magnetic induction intensity. According to the change of capacitance or the change of magnetic induction intensity, the working condition of the dehumidifier is controlled. When the capacitance or magnetic induction intensity reaches a preset value, the dehumidifier stops working. A receiving slot <NUM> that may completely receive the float <NUM> is defined at the bottom of the machine body <NUM>. When the dehumidifier is in the idle state, the float <NUM> may be completely received in the receiving slot <NUM>.

In this embodiment, by providing the water level switch <NUM> at the bottom of the machine body <NUM>, and defining a receiving slot <NUM> recessed into the machine body <NUM> at the bottom of the machine body <NUM>, the float <NUM> may be completely received in the receiving slot <NUM> when in the idle state, so that the float <NUM> may not protrude from the machine body <NUM>. In this way, the machine body <NUM> may be stably placed on the ground and the water tank <NUM>, and it is also beneficial for the machine body <NUM> to be quickly placed in the water tank <NUM>.

In some embodiments, in order to ensure that the float <NUM> may accurately enter the receiving slot <NUM>, the water level switch <NUM> further includes a guide rod <NUM> connected to the float <NUM>, and the machine body <NUM> defines a guide hole <NUM> communicating with the receiving slot <NUM>. An end of the guide rod <NUM> away from the float <NUM> is movably mounted in the guide hole <NUM>. By providing the guide rod <NUM> and the guide hole <NUM>, the guide rod <NUM> may be moved along the guide hole <NUM>. With the force of the float <NUM> on the guide rod <NUM>, the guide rod <NUM> may be moved along the guide hole <NUM> toward the inside of the machine body <NUM>. When the machine body <NUM> is placed on the ground, the float <NUM> is completely squeezed into the receiving slot <NUM>.

In some embodiments, in order to ensure the flexibility of the movement of the float <NUM>, the guide hole <NUM> is vertically defined directly above the receiving slot <NUM>. In this way, the guide rod <NUM> and the float <NUM> may be moved straight up and down along the guide hole <NUM>, so that the movement directions of the float <NUM> and the guide rod <NUM> are consistent with a force direction of the float <NUM> (gravity and buoyancy of water on the float <NUM>), which is beneficial for the float <NUM> to be moved up and down.

In some embodiments, in order to improve the accuracy and sensitivity of water level detection, the water level switch <NUM> may be a magnetic control switch, and the detection state of the water level switch <NUM> includes an open state and a closed state. In the detection state, the float <NUM> is extended from the receiving slot <NUM> and protruded from the bottom of the machine body <NUM>. Specifically, the water level switch <NUM> includes a magnetic float switch. A magnetic member may be provided in the float to change the magnetic field as the float <NUM> moves. As the float <NUM> rises, an intensity of the magnetic field at the bottom of the machine body <NUM> increases. By setting the water level switch <NUM> as a magnetic control switch, the water level switch <NUM> may quickly and accurately detect the current water level. In some embodiments, the water level switch <NUM> may be electrically connected to the electric control main board of the dehumidifier. The dehumidifier further includes an alarm device, and the alarm device is electrically connected to the electric control main board and/or the water level switch <NUM>.

Referring to <FIG>, regarding axial flow air duct system.

The dehumidifier includes: a machine body <NUM> including a case <NUM>, the case <NUM> defining an air inlet <NUM>, an air outlet <NUM>, and an air duct communicating the air inlet <NUM> and the air outlet <NUM>;.

Specifically, in this embodiment, the axial flow fan and the compressor <NUM> are arranged in parallel, and the two may be extended in many directions, such as both being arranged vertically or both being arranged horizontally. Taking the two both being arranged vertically as an example, the two at least partially overlap in the vertical direction. For example, a top of the compressor <NUM> is extended to a middle or an upper part of the drive motor <NUM>. Compared with the traditional layout (the compressor <NUM> and the axial flow fan are separately arranged on two layers, and there is no overlap between the two), the arrangement of the compressor <NUM> and the axial flow fan greatly reduces a height of the entire machine body <NUM>.

In this embodiment, by arranging the axial flow fan and the compressor <NUM> in parallel, compared to the traditional arrangement of upper and lower layers, the space occupied by the axial flow fan and the compressor <NUM> in the height direction is greatly reduced, thereby improving the compactness of the internal components of the dehumidifier, so that the height of the machine body <NUM> may be greatly reduced, which is conducive to reducing the height and volume of the machine body <NUM>, thereby facilitating the transportation and storage of the machine body <NUM>. In addition, since the arrangement of the machine body <NUM> does not need to consider the arrangement of the water tank <NUM>, the arrangement of the components inside the machine body <NUM> is more reasonable and compact.

In some embodiments, in order to further improve the compactness of the structures and the heat exchange efficiency of the heat exchanger, the dehumidifier includes an evaporator <NUM> and a condenser <NUM> that are stacked. The evaporator <NUM> and/or the condenser <NUM> are arranged in the air duct in a U shape, and the axial flow fan is located in an area enclosed by the evaporator <NUM> and the condenser <NUM>.

Specifically, in this embodiment, the evaporator <NUM> and/or the condenser <NUM> are arranged in a U shape, so that the axial flow fan may be arranged in the U-shaped area. In this way, the space is fully utilized and the compactness of the structures is improved, so that each part of the evaporator <NUM> and the condenser <NUM> may have considerable negative pressure (the axial flow fan delivers the air in the U-shaped area out of the air duct, and the negative pressure is formed in the U-shaped area), so that the air flows passing through the parts of the evaporator <NUM> and the condenser <NUM> are equivalent, which is beneficial to greatly improving the efficiencies of the evaporator <NUM> and the heat exchanger.

In addition, by arranging the evaporator <NUM> and the condenser <NUM> to be U-shaped, heat exchanger efficiencies of the evaporator <NUM> and the condenser <NUM> are greatly increased, which is beneficial to improving the dehumidification efficiency of the dehumidifier. In order to further improve the heat exchanger efficiencies of the evaporator <NUM> and the condenser <NUM>, air inlets <NUM> are defined corresponding to multiple surfaces of the U-shaped evaporator <NUM> and condenser <NUM>. Taking the air inlets <NUM> being defined on the left, right, and rear sides as an example, the air inlets <NUM> correspond to the U-shaped area on both lateral arms and a middle part respectively. In this way, sufficient air flow is provided for the heat exchange between the evaporator <NUM> and the condenser <NUM>.

In some embodiments, in order to improve the dehumidification effect, the evaporator <NUM> is disposed close to an inner side wall of the case <NUM>, and the condenser <NUM> is disposed close to the axial flow fan. The air is first cooled and dehumidified through the evaporator <NUM>, and then heated back to the temperature through the condenser <NUM>, which is beneficial to improving the dehumidification effect.

The air inlet <NUM> is defined at the top of the machine body <NUM>, and a bottom of the compressor <NUM> is fixedly connected to a bottom of the case <NUM> and is arranged vertically. The axial flow fan includes a drive motor <NUM> and an axial flow wind wheel <NUM>. The drive motor <NUM> is vertically arranged corresponding to the air outlet <NUM>, and the axial flow wind wheel <NUM> is arranged close to the air outlet <NUM>. With this arrangement, when the drive motor <NUM> drives the axial flow wind wheel <NUM> to rotate, the axial flow wind wheel <NUM> may efficiently send the dry air in the air duct out of the dehumidifier, which is beneficial to air flow and improves dehumidification efficiency.

In some embodiments, in order to further improve the compactness of the structures, the dehumidifier includes a machine body <NUM>, and the machine body <NUM> includes:.

Specifically, in this embodiment, the water receiving tray <NUM> is disposed directly below the condenser <NUM>, the evaporator <NUM> and the axial flow fan, and the case <NUM> is divided to define the axial flow air duct and the receiving cavity for mounting other components. The water receiving tray <NUM> is in the shape of a flat plate. It not only has parts corresponding to the condenser <NUM> and the evaporator <NUM>, but also has parts corresponding to the axial flow fan, so that the airflow in the axial flow air duct may be directly flown out of the air outlet <NUM> without scurrying in the air duct. Taking the evaporator <NUM>, the condenser <NUM>, and the axial flow fan being all arranged vertically as an example.

In this embodiment, the axial flow fan is taken as the driving force of the air flow, and the axial flow fan is arranged in parallel with the evaporator <NUM> and the condenser <NUM> in the vertical direction, so that the centralized arrangement of the three is conducive to the full and reasonable use of space. At the same time, the water receiving tray <NUM> is arranged directly below the evaporator <NUM>, the condenser <NUM> and the axial flow fan, so that the case <NUM> is divided to define an axial flow air duct for heat exchange and a mounting cavity for mounting other common components of the dehumidifier (such as an electric control box <NUM>, a fan capacitor <NUM>, etc.). In this way, it not only makes full and reasonable use of space, but also ensures the rationality of the air duct (to avoid excessive dispersion of airflow in the case <NUM>, resulting in low flow rate and affecting dehumidification efficiency). In this way, the compactness of the internal components of the dehumidifier is improved, the utilization of space is improved, and the volume of the machine body <NUM> is reduced, thereby facilitating the transportation and storage of the machine body <NUM>. In addition, since the arrangement of the machine body <NUM> does not need to consider the arrangement of the water tank <NUM>, the arrangement of the components inside the machine body <NUM> is more reasonable and compact.

In some embodiments, in order to further improve the space utilization rate, the compressor <NUM> of the dehumidifier is vertically arranged at the bottom of the case <NUM>, and the water receiving tray <NUM> defines an avoidance notch corresponding to the compressor <NUM>. The compressor <NUM> is arranged in parallel with the axial flow fan, and a top of the compressor <NUM> is extended to a middle or even an upper part of the axial flow fan.

In order to further improve space utilization and ease of installation of components, the dehumidifier further includes a partition plate <NUM>. The partition plate <NUM> is located in the mounting cavity, and one side of the partition plate <NUM> is connected to the bottom of the case <NUM>, and the opposite side is fixedly connected to a bottom of the water receiving tray <NUM>. The partition plate <NUM> supports the water receiving tray <NUM>. When the evaporator <NUM>, the condenser <NUM> and the axial flow fan fall on the water receiving tray <NUM> during transportation or collision, the partition plate <NUM> may support the water receiving tray <NUM> to avoid the evaporator <NUM>, the condenser <NUM> and the axial flow fan from being damaged by a large collision. At the same time, the partition plate <NUM> also provides a location for the mounting of components, so that multiple components of the dehumidifier may be conveniently mounted on the partition plate <NUM>.

Specifically, an electric control box <NUM> is provided on the partition plate <NUM>, and/or a fan capacitor <NUM> is provided on the partition plate <NUM>, and/or a water level switch <NUM> is provided in the mounting cavity. That is, the electrical control box <NUM> and the fan capacitor <NUM> may be provided on the partition plate <NUM>, and the water level switch <NUM> may also be provided on the partition plate <NUM>. In this way, while providing support for the components in the axial flow air duct, the partition plate <NUM> also provides space for the mounting of components. In order to use the space more reasonably, the fan capacitor <NUM>, the electric control box <NUM>, etc., may be mounted on different partition plates <NUM>.

In order to further utilize the space, the partition plate <NUM> includes at least two sub-partition plates, which are arranged in the receiving cavity at an angle. The dehumidifier includes a compressor capacitor <NUM> and an electric control box <NUM>, and the compressor capacitor <NUM> and the electric control box <NUM> are mounted on different sub-partition plates. For example, the electric control box <NUM> is mounted on the sub-partition plate on the right side, and the compressor capacitor <NUM> is mounted on the sub-partition plate on the rear side. In this way, the larger components are arranged separately, so that the components are mounted without affecting each other, which is beneficial to improving the compactness and stability of the structures.

In some embodiments, in order to improve the reliability of the mounting of the compressor capacitor <NUM> and increase the utilization of space, the dehumidifier further includes an arc-shaped fastening piece. The sub-partition plate where the compressor capacitor <NUM> is mounted defines a mounting gap <NUM>, the compressor capacitor <NUM> is clamped in the mounting gap <NUM> and is fixed on the sub-partition plate through the arc-shaped fastening piece.

In order to further improve the compactness of the structures, the evaporator <NUM> and the condenser <NUM> are arranged in the case <NUM> in a U shape, and the axial flow fan is located in an area enclosed by the evaporator <NUM> and the condenser <NUM>. The air outlet <NUM> is defined at the top of the case <NUM>, and a bottom of the compressor <NUM> is fixedly connected to a bottom of the case <NUM> and is arranged vertically. The axial flow fan includes a drive motor <NUM> and an axial flow wind wheel <NUM>. The drive motor <NUM> is vertically arranged corresponding to the air outlet <NUM>, and the axial flow wind wheel <NUM> is arranged close to the air outlet <NUM>.

In some embodiments, in order to ensure the drainage of the dehumidifier, a drainage hole <NUM> is defined on the rear side of the case <NUM>, one end of the drainage hole <NUM> is in communication with the water receiving tray <NUM>, and the other end of the drainage hole <NUM> is in communication with the outside; and/or, the machine body <NUM> defines a drainage passage <NUM> arranged along the height direction of the machine body <NUM>, one end of the drainage passage <NUM> is in communication with the water receiving tray <NUM>, and the other end of the drainage passage <NUM> is in communication with the direct bottom of the machine body <NUM>. That is, the dehumidifier has two sets of drainage systems. When the dehumidifier can be connected to an external drainage pipe, the condensed water may be directly discharged through the external drainage pipe. When the working environment cannot provide an external drainage pipe, the condensed water may be stored in the water tank <NUM> under the machine body <NUM> through the drainage passage <NUM>. In this way, the dehumidifier may be adapted to different working environments, which is beneficial to improving the adaptability of the dehumidifier.

Referring to <FIG>, regarding lifting handle <NUM>'.

The dehumidifier includes a lifting handle <NUM>'. The top of the machine body <NUM> defines a drawing port, and the lifting handle <NUM>' is movably mounted in the drawing port, so that the lifting handle <NUM>' does not protrude from the peripheral side of the machine body <NUM> in the working state or the idle state.

In this embodiment, the dehumidifier is divided into two parts: a machine body <NUM> and a water tank <NUM>, and the machine body <NUM> has an independent dehumidification function, which may collect water vapor in the air, and in an idle state, the machine body <NUM> is at least partially received in the receiving cavity <NUM>, which greatly reduces the volume of the dehumidifier when it is idle, and increases the amount of containers during storage and transportation, which greatly saves the cost of transportation and storage. At the same time, by defining the drawing port on the top of the machine body <NUM>, and movably mounting the lifting handle <NUM>' in the drawing port, the lifting handle <NUM>' does not protrude from the peripheral side of the machine body <NUM> in the working state or the idle state, so that the machine body <NUM> may be conveniently and quickly loaded into the water tank <NUM>.

In some embodiments, in order to further improve the compactness of the structures, the machine body <NUM> defines a receiving space, and the lifting handle <NUM>' may be received in the receiving space when the lifting handle <NUM>' is idle. By arranging the receiving space, the lifting handle <NUM>' may be received in the space without protruding from the top of the machine body <NUM>. As a result, the lifting handle <NUM>' does not block the view of the top of the machine body <NUM>, does not affect the viewing of the display device <NUM>, and does not affect the air outlet from the air outlet <NUM>.

The lifting handle <NUM>' includes a horizontal grip rod <NUM>' and a vertical guide rod <NUM>'. One end of the guide rod <NUM>' is connected to the grip rod <NUM>', and the guide rod <NUM>' defines a guide slot <NUM>' with two ends closed. A fixed column <NUM>' is provided on the machine body <NUM> corresponding to the drawing port, and the guide slot <NUM>' is sleeved on the fixed column <NUM>'.

The fixed column <NUM>' is fixedly connected to the machine body <NUM>. When the lifting handle <NUM>' is lifted up, a lower end of the guide slot <NUM>' is abutted against the fixed column <NUM>', and the weight of the machine body <NUM> is transmitted to the lifting handle <NUM>' through the fixed column <NUM>'. When the lifting handle <NUM>' is placed downward, an upper end of the guide slot <NUM>' is abutted against the fixed column <NUM>' to support the lifting handle <NUM>'. In some embodiments, in order to improve the reliability of lifting the machine body <NUM> by the lifting handle <NUM>', a number of the guide rod <NUM>' is two, and the two guide rods <NUM>' are respectively arranged on two ends of the grip rod <NUM>'. In this way, the machine body <NUM> may receive forces on opposite sides, so that the machine body <NUM> receives more uniform forces.

In order to improve the space utilization of the dehumidifier, when the lifting handle <NUM>' is idle, a top of the grip rod <NUM>' is flush with the top of the machine body <NUM>, and a hand grip position <NUM> is provided on one side of the drawing port. By providing the hand grip position <NUM>, the operator may easily hold the lifting handle <NUM>'.

In this way, the hand grip position <NUM> does not occupy the area of the air outlet <NUM>, so that the area of the air outlet <NUM> may be larger.

In order to further improve the space utilization of the dehumidifier, a fan is provided inside the machine body <NUM>, and an enclosure <NUM> is provided corresponding to the fan. The enclosure <NUM> defines an avoidance notch that avoids the guide rod <NUM>'. By arranging the avoidance gap, the structure of the air duct is ensured, and the lifting handle <NUM>' may be received.

Referring to <FIG>, in some embodiments, the dehumidifier includes a handle <NUM>. The top of the machine body <NUM> is provided with a mounting recess <NUM>. The handle <NUM> is rotationally connected to a side wall of the mounting recess <NUM>, so that the handle <NUM> does not protrude from the peripheral side of the machine body <NUM> when in the working state or when in the idle state.

In this embodiment, in addition to reducing the volume of the dehumidifier in the idle state, by defining the mounting recess <NUM> on the top of the machine body <NUM> and rotationally connect the handle <NUM> to the side wall of the mounting recess <NUM>, the handle <NUM> does not protrude from the peripheral side of the machine body <NUM> in the working state or the idle state, so that the machine body <NUM> may be conveniently and quickly loaded into the water tank <NUM>.

In some embodiments, in order to further improve the compactness of the structures, when the handle <NUM> is idle, the handle <NUM> may be received in the mounting recess <NUM>. A depth of the mounting recess <NUM> is greater than or equal to a height of the handle <NUM> when placed horizontally. The mounting recess <NUM> is located at an edge of the top of the machine body <NUM>. When the handle <NUM> is received in the mounting recess <NUM>, an outer side wall of the handle <NUM> is flush with the outer side wall of the machine body <NUM>; and/or, a top of the handle <NUM> is flush with the top of the machine body <NUM>. In this way, the handle <NUM> is kept away from a middle of the top of the machine body <NUM>, and the layout of the top of the machine body <NUM> is not affected.

In addition, because the handle <NUM> is not arranged in the middle of the top of the machine body <NUM>, but on the edge of the top of the machine body <NUM>, the area of the air outlet <NUM> on the top may be set according to requirements, thereby effectively ensuring the air outlet area and efficiency, which is beneficial to ensuring the working efficiency of the dehumidifier.

In some embodiments, in order to facilitate gripping of the handle <NUM>, the top of the water tank <NUM> defines a hand grip notch <NUM> corresponding to the handle <NUM>. The arrangement of the hand grip notch <NUM> allows the operator to directly hold the handle <NUM> through the hand grip notch <NUM>, which facilitates the operation of the handle <NUM>.

In some embodiments, in order to improve the reliability of lifting the machine body <NUM> by the lifting handle <NUM>', the handle <NUM> includes a lateral hand rod <NUM> and two connection rods <NUM>.
