According to <FIG>, in one embodiment of the present application, the dehumidifier includes:.

According to the technical solution of the present application, a filter net slot configured beside the air inlet <NUM> is configured on the machine body <NUM> for the filter net <NUM> to be pulled and inserted, so that when the filter net <NUM> is to be cleaned or replaced, it is not needed to disassemble a shell of the machine body <NUM>, but only needed to pull the filter net <NUM> out of the filter net slot to disassemble the filter net <NUM>. The convenience of disassembly and assembly to clean or replace the filter net <NUM> of the dehumidifier is improved, and the user experience is improved. In addition, in the dehumidifier of the present application, the machine body <NUM> extends out relative to the water tank <NUM> in the working state, so that an air outlet on the machine body <NUM> has a higher position, and dehumidified air can be discharged to a higher position and spread to a whole indoor space faster. In the idle state, the machine body <NUM> can be accommodated in the water tank <NUM> as much as possible, so that an overall center of gravity of the dehumidifier is lower, making a placement of the dehumidifier more stable, reducing probability of falling of the dehumidifier, and also reducing an overall occupied space for the dehumidifier to be placed in the idle state, and facilitating users to place the dehumidifier.

In this embodiment, optionally, the mounting port is configured as an open port, so that a side wall <NUM> of the water tank <NUM> can provide a downward guide for reception of the machine body <NUM>, and the open port can facilitate receiving of water droplets formed by dehumidification. However, the present design is not limited to this, in other embodiments, the mounting port may not be provided as an open port.

According to <FIG>, further, the machine body <NUM> includes the side wall <NUM>. The air inlet <NUM> is provided on the side wall <NUM>. The filter net slot includes an upper slot 202a for inserting an upper side of the filter net <NUM>, and a lower slot 202b for inserting a lower side of the filter net <NUM>. It can be understood that in this embodiment, the filter net slot extends in a transverse direction or substantially in the transverse direction, that is, the filter net <NUM> is inserted into the filter net slot in a transverse pulling manner, and a user can remove the filter net <NUM> by applying a transverse pulling force to the filter net <NUM>. However, the present design is not limited to here, in other embodiments, the filter net slot may extend in an up-and-down direction.

Further, the filter net slot is configured in the machine body <NUM>, and the side wall <NUM> is provided with a filter net mounting port <NUM> for the filter net <NUM> to be inserted. As such, it is possible for the shell of the machine body <NUM> to provide physical protection for the filter net <NUM>. In this technical scheme, when cleaning or replacing the filter net <NUM>, the user can pull the filter net <NUM> out of the filter net slot through the filter net mounting port <NUM>, and insert the filter net <NUM> into the filter net slot through the filter net mounting port <NUM> after cleaning or replacing.

According to <FIG>, the machine body <NUM> further includes a top cover <NUM> connected to an upper end of the side wall <NUM>, and a water receiving tray <NUM> connected to a lower end of the side wall <NUM>. The upper slot 202a is defined on the top cover <NUM>, and the lower slot 202b is defined on the water receiving tray <NUM>. That is, in this embodiment, the air inlet <NUM>, the upper slot 202a, and the lower slot 202b are respectively defined on the side wall <NUM>, the top cover <NUM>, and the water receiving tray <NUM>, and the side wall <NUM>, the top cover <NUM>, and the water receiving tray <NUM> can be correspondingly processed during preparation, thereby reducing processing complexity of a single component and improving processing efficiency of the product. However, this design is not limited to this. In other embodiments, the upper slot 202a and the lower slot 202b can be defined at the upper end and the lower end of the side wall <NUM>.

Further, two upper guide rails <NUM> are formed on the top cover <NUM>, being parallel to each other and spaced from each other, to form the upper slot 202a between the two upper guide rails <NUM>. In this way, heights of the upper guide rails <NUM> can be conveniently set to meet a depth requirement of the upper slot 202a. In addition, compared with the technical scheme in which the upper slot 202a is recessed and molded on the top cover <NUM>, a thickness of the top cover <NUM> is smaller, thereby saving the material required for the top cover <NUM> and reducing the cost of the product.

Similarly, two lower guide rails <NUM> are formed on the water receiving tray <NUM>, being parallel to each other and spaced from each other, to form the lower slot 202b between the two lower guide rails <NUM>. In this way, a depth requirement of the lower slot 202b can be conveniently met by setting heights of the lower guide rails <NUM>. In addition, compared with the technical scheme in which the lower slot 202b is recessed and molded on the water receiving tray <NUM>, a thickness of the water receiving tray <NUM> is smaller, thereby saving the materials required for the water receiving tray <NUM> and reducing the cost of the product.

According to <FIG>, <FIG> and <FIG>, further, the side wall <NUM> includes a first side wall <NUM>, a second side wall <NUM> and a third side wall <NUM> being connected in sequence, where the first side wall <NUM> is opposite to the third side wall <NUM>, and the first side wall <NUM>, the second side wall <NUM> and the third side wall <NUM> are all defined with an air inlet <NUM>. In this way, a "three-sided air inlet" channel can be formed on the machine body <NUM>, and an air treatment area can be increased compared with a "one-sided air inlet" channel, thereby improving the air treatment efficiency. In addition, by adopting a mode of "three-sided air inlet", an air inlet speed can be reduced under the same air volume, thus reducing the static pressure loss and enabling a fan in the machine body <NUM> to operate efficiently. In this embodiment, optionally, the air inlet <NUM> comprises a plurality of air inlet holes configured in an array. However, this design is not limited to this, in other embodiments, the air inlet <NUM> may be configured in a grid shape.

In this embodiment, optionally, a dehumidification device of the dehumidifier includes a compressor, an evaporator <NUM> and a condenser <NUM>. First, water vapor in the air is condensed into water droplets by the evaporator <NUM> to remove water vapor in the air, and then the air after the water vapor is removed is heated and dried by the condenser <NUM> to restore blown air to normal temperature. Of course, in other embodiments, the dehumidification device can adopt a dehumidification method such as adsorption type. In this embodiment, the evaporator <NUM> is provided with a first evaporation section, a second evaporation section and a third evaporation section corresponding to the air inlet <NUM> on the first side wall <NUM>, the second side wall <NUM> and the third side wall <NUM>, respectively. The first evaporation section is opposite to the third evaporation section, that is, the evaporator <NUM> is approximately U-shaped.

According to <FIG>, <FIG> and <FIG>, further, the filter net <NUM> includes two filter subnets <NUM> that are spliced in a circumferential direction of the machine body <NUM>. One of the filter subnets <NUM> covers the air inlet <NUM> on the first side wall <NUM> and a part of the air inlet <NUM> an the second side wall <NUM>. The other of the filter <NUM> covers the other part of the air inlet <NUM> on the second side wall <NUM> and the air inlet <NUM> on the third side wall <NUM>. Each of the first side wall <NUM> and the third side wall <NUM> is provided with a filter net mounting port <NUM> for the two filter subnets <NUM> to be mounted. Obviously, in this embodiment, the two filter subnets <NUM> each have their own mounting and dismounting ports, and each of the filter subnets <NUM> only needs to pass through one corner during the mounting process, that is, each of the filter subnets <NUM> only needs to be bent once. Compared with the technical scheme of only setting one integrated filter net <NUM>, the mounting of the filter subnets <NUM> is more convenient. In this embodiment, the filter subnets <NUM> need to have certain flexibility, so that they can bend themselves and be suitable for loading during sliding along the filter slot for insertion. Of course, each of the filter subnets <NUM> also needs to have some rigidity in order to be pushed into the filter slot as a whole. Generally, each of the filter subnets <NUM> may be configured as a plastic filter net. Of course, each of the filter subnets <NUM> can include a plastic frame and a flexible filter net configured on the plastic frame. Optionally, the two filter subnets <NUM> are spliced in the middle of the second side wall <NUM>, that is, the two filter subnets <NUM> are equal in length, so that the two filter subnets <NUM> can have same specifications and facilitate preparation.

Generally, the side wall <NUM> also includes a fourth side wall <NUM> opposite to the second side wall <NUM>. The fourth side wall <NUM> is generally disposed against a wall. In this embodiment, the two filter net mounting ports <NUM> are respectively defined on the first side wall <NUM> and the third side wall <NUM>, so that the filter subnets <NUM> can be assembled and disassembled without moving the dehumidifier, and the user can use the dehumidifier more conveniently. However, the present design is not limited to this. In other embodiments, the two filter net mounting ports <NUM> may be defined on the fourth side wall <NUM> to hide the filter net mounting ports <NUM> in a position invisible to the user. In this embodiment, optionally, in order to improve the insertion smoothness of the filter subnets <NUM>, each of the first side wall <NUM> and the third side wall <NUM> is configured with an inclined transition channel communicating the filter net mounting port <NUM> and the filter net slot.

According to <FIG>, <FIG> and <FIG>, further, one end of each of the filter subnets <NUM> is configured with a blocking member <NUM>, and the other end of the filter subnet <NUM> is inserted into the filter slot from the filter net mounting port <NUM> until the blocking member <NUM> blocks the filter net mounting port <NUM>. It can be understood that the filter net mounting port <NUM> is blocked by the blocking member <NUM>, so that particulate matters such as dusts can be prevented from entering the dehumidifier through the filter net mounting port <NUM>.

Further, the blocking member <NUM> is provided with a clasp <NUM> configured in a recessed manner. In this way, the filter subnet <NUM> can be easily pulled out, and at the same time, the clasp <NUM> is recessed, so that it avoids the situation that the clasp <NUM> prevents the machine body <NUM> from being accommodated in the water tank <NUM>. Of course, in other embodiments, the blocking member <NUM> may also be configured with a convex handle, as such, an avoidance notch is needed to be configured in the mounting port of the water tank <NUM>, or the handle is needed to be provided at an upper position, and when the dehumidifier is in the idle state, the handle is exposed outside the water tank <NUM>.

Further, an anti-disengagement structure is configured between each filter subnet <NUM> and the machine body <NUM>, so that each filter subnet <NUM> can be positioned in the machine body <NUM> after being installed in the filter net slot, thereby preventing the filter subnet <NUM> from dropping out, and further improving assembly reliability of the filter subnet <NUM>.

Further, the anti-disengagement structure includes a buckle hole <NUM> provided on the filter subnet <NUM>, and a buckle <NUM> provided on an inner side of the filter mounting port <NUM>. After the filter subnet <NUM> is installed in the filter net slot, the buckle <NUM> can be engaged to the buckle hole <NUM> to restrict the filter subnet <NUM> from leaving the filter net mounting port <NUM>. In this embodiment, the buckle hole <NUM> can be configured on the filter net of the filter subnet <NUM> or on the blocking member <NUM> thereof. Optionally, the filter subnet <NUM> includes a subnet body 31a and a subnet flange 31b configured in parallel on the same side of the blocking member <NUM>. The buckle hole <NUM> is defined on the subnet flange 31b. In this way, the buckle hole <NUM> can be prevented from damaging an overall structure of the subnet body 31a, and probability of tearing of the subnet body 31a can be reduced. In the technical scheme, the anti-disengagement structure is configured as a clamping structure, so that mounting and disassembly of the filter subnet <NUM> relative to the filter net mounting port <NUM> can be realized without additional tools (such as a screwdriver). However, the present design is not limited to this, in other embodiments, the anti-disengagement structure may be configured as, but not limited to, a screw-locking structure or the like.

According to <FIG>, further, the machine body <NUM> is configured with a protective baffle <NUM> opposite to the filter net mounting port <NUM> and spaced from the filter net mounting port <NUM>. In this way, after the filter net <NUM> is pulled out, a user can be restricted by the protective baffle <NUM> from extending hands or other objects into the machine body <NUM> to touch an electronic control wiring, a pipeline of the evaporator <NUM> or the like in the machine body <NUM>.
