Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the present invention, "a plurality" means two or more unless otherwise specified.

Referring to fig. 1 and 2, the dehumidifier provided by the embodiment of the invention comprises a housing, an evaporator 1 is arranged in the housing, a water pan 2 is arranged below the evaporator 1, a water box 3 is connected to an outlet of the water pan 2, and the dehumidifier further comprises a filter screen assembly 4, wherein the filter screen assembly 4 is detachably inserted between the outlet of the water pan 2 and an inlet of the water box 3 from the outside of the housing.

According to the dehumidifier provided by the embodiment of the invention, the filter screen assembly 4 is detachably inserted between the outlet of the water receiving tray 2 and the inlet of the water box 3 from the outside of the shell, so that when the filter screen assembly 4 needs to be disassembled and washed or replaced, the filter screen assembly 4 only needs to be drawn out, and the filter screen assembly is cleaned or replaced and then inserted back into the dehumidifier. Therefore, the filter screen can be detached and washed conveniently by a user, and the filter screen is prevented from being blocked.

Specifically, as shown in fig. 2, the filter screen assembly 4 includes a drawer housing 41, a water inlet 42 and a water outlet 43 are provided on the drawer housing 41, the water inlet 42 of the drawer housing 41 is opposite to the outlet of the water pan 2, the water outlet 43 of the drawer housing 41 is opposite to the inlet of the water box 3, a filter screen 44 is provided in the drawer housing 41, and the filter screen 44 is located between the water inlet 42 of the drawer housing 41 and the water outlet 43 of the drawer housing 41. Condensed water generated by the evaporator 1 drips into the water pan 2, then flows into the water inlet 42 of the drawer housing 41 from the outlet of the water pan 2, is filtered by the filter screen 44 in the drawer housing 41, and then flows into the water box 3 from the water outlet 43 of the drawer housing 41. Thereby, the filtering of the condensed water can be achieved, and the drawer housing 41 is convenient to draw.

Wherein, the filter screen 44 can be horizontally arranged in the drawer shell 41 as shown in fig. 3, one end of the filter screen 44 is directly opposite to the outlet of the water pan 2, at this time, only the part of the filter screen 44 close to the outlet of the water pan 2 can be utilized, and the filter screens 44 of the rest parts are not easy to be utilized, so that the available area of the filter screen 44 is small, thereby generating waste. In order to increase the available area of the filter screen 44, as shown in fig. 2, a water inlet cavity 45, a filter cavity 46 and a main water outlet cavity 47 may be formed in the drawer housing 41, the filter screen 44 is horizontally disposed in the filter cavity 46, a peripheral edge of the filter screen 44 is tightly attached to an inner wall of the filter cavity 46, the water inlet 42 of the drawer housing 41 is communicated with the water inlet cavity 45, the bottom of the water inlet cavity 45 is communicated with the bottom of the filter cavity 46, the top of the filter cavity 46 is communicated with the top of the main water outlet cavity 47, and the water outlet 43 of the drawer housing 41 is disposed at the bottom of the main water outlet cavity 47. At this time, the condensed water flows into the water inlet 42 of the drawer housing 41, then enters the water inlet cavity 45, enters the filter cavity 46 from the bottom of the water inlet cavity 45, flows over the filter screen 44 in the filter cavity 46, enters the main water outlet cavity 47 from the top of the filter cavity 46, and finally enters the water box 3 from the bottom water outlet 43 of the main water outlet cavity 47 (i.e., the water outlet 43 of the drawer housing 41). In the process, since the condensed water in the filtering chamber 46 is over the whole filtering net 44, the whole filtering net 44 can be used for filtering the condensed water. The utilization area of the filter screen 44 is increased, and the service life of the filter screen 44 is prolonged. In addition, this scheme is because the direction of rivers through filter screen 44 is the antigravity route, and water is from bottom to top through filter screen 44, and this design can let the water that contains more impurity, utilizes the action of gravity to carry out preliminary sedimentation earlier in the bottom A region of filter chamber 46, then rises along with the surface of water, passes through filter screen 44 uniformly to the B region to can prevent hard or big granule impurity damage filter screen 44.

Because a user may forget to clean the filter screen 44 when using the dehumidifier, the filter screen 44 may be blocked after long-term use, and in order to prevent the condensed water from overflowing from the drawer housing 41 and flowing into the dehumidifier, which may cause a safety hazard, it is preferable that, as shown in fig. 4, the first partition 451 between the water inlet chamber 45 and the filter chamber 46 is set lower than the side wall 411 of the drawer housing 41, so that when the filter screen 44 is blocked, the condensed water may overflow into the filter chamber 46 from the upper portion of the first partition 451, enter the main water outlet chamber 47 from the top of the filter chamber 46, and finally enter the water box 3.

In addition, as shown in fig. 4, a spare water outlet cavity 48 may be further disposed in the drawer housing 41, the water inlet cavity 45 is separated from the filter cavity 46 by a first partition 451, the spare water outlet cavity 48 is separated from the water inlet cavity 45 by a second partition 452, an upper end of the first partition 451 is higher than an upper end of the second partition 452, a spare water outlet 481 is disposed at a bottom of the spare water outlet cavity 48, and the spare water outlet 481 is communicated with an inlet of the water cartridge 3. Therefore, when the filter screen 44 is blocked, the condensed water can flow into the spare water outlet cavity 48 from the upper part of the second partition 452, and enter the water box 3 from the spare water outlet 481 at the bottom of the spare water outlet cavity 48. Thereby preventing the condensed water from flowing into the interior of the dehumidifier and causing potential safety hazard.

The filter screen 44 may be one layer or a plurality of layers, and in order to improve the filtering effect, it is preferable to provide the filter screen 44 in a plurality of layers, and the filter screens 44 in the plurality of layers are stacked. Thereby, multi-stage filtration can be achieved.

Preferably, the filtering precision of the multiple layers of the filtering screens can be different, so that the filtering forms in the filtering box can be combined randomly according to the requirements of different customers. For example, the filtration accuracy of each layer of filter screen may increase in the direction of flow of the water. As shown in fig. 2, the coarse filter screen 441 filters large foreign substances so that they cannot block the water pump, and the fine filter screen 442 filters fine particles in the water so that they cannot flow toward the large tank along with the water and adhere to the inner wall of the tank. On the basis of the configuration, a silver ion sterilization (or activated carbon filtration) function can be added to the coarse filter screen 441, or the material of the drawer shell 41 is changed into silver ion injection molding, so that the whole large water tank does not need to be subjected to silver ion injection molding, and the manufacturing cost is greatly reduced.

In order to improve the filtering effect, as shown in fig. 2 and 4, two adjacent layers of the filtering net are arranged at intervals. Therefore, a mixed flow space can be formed between two adjacent layers of filter screens, so that water filtered by the previous layer of filter screen can be uniformly mixed in the mixed flow space and then passes through the next layer of filter screen. Thereby improving the filtering effect.

As shown in fig. 1 and 2, the filter screen assembly 4 can be inserted into the dehumidifier from the rear plate 5 of the dehumidifier in a horizontal direction. The back plate 5 is arranged on the back of the shell, so that the appearance of the dehumidifier is not affected.

In order to quickly discharge the condensed water, it is preferable that, as shown in fig. 2, a water pump inlet 6 is provided below the water box 3, and a water pump (not shown) is connected to the water pump inlet 6, so that the condensed water in the water box 3 can be discharged by the water pump.

Specifically, a water tank (not shown) may be further provided, the volume of the water tank is greater than that of the water box 3, a separation dam 31 is disposed on a side of the water box 3 close to the water tank, and when the water level in the water box 3 overflows the separation dam 31, the water can enter the water outlet nozzle 7 and enter the water tank through the water outlet nozzle 7. Therefore, when the water pump drainage function is not started, the water in the water box 3 can overflow into the water tank. Therefore, the energy consumption of the water pump can be reduced, and because the condensed water is filtered firstly, then enters the water box 3 and finally flows into the water tank, the excessive dirt accumulated on the inner wall of the water tank can be prevented, and the user experience is improved. In addition, the water outlet nozzle 7 can be directly connected with a drain pipe without being connected with a water tank and is discharged outdoors.

The dehumidifier of the embodiment of the application can adopt the following drainage modes:

firstly, when the water pump drainage function is started, a user presses a corresponding button to start a program, when the water tank 3 is full of water to a certain height, a sensor is triggered, and the water pump starts to pump water in the water tank 3 and discharge the water out of a room. At this time, the water does not go over the separation dam 31, and the water outlet nozzle 7 does not have water.

When the water pump drainage function is not started, the water pump does not work, water in the water box 3 gradually overflows the separation dam 31 when full, and enters the water outlet nozzle 7, when the water outlet nozzle 7 is not connected with a drainage pipe, the water is directly discharged into a water tank below through the water outlet nozzle 7, and after the water tank is full, the sensor is touched, so that the dehumidifier is automatically stopped, and the alarm is triggered to give an alarm to remind a user of taking out the water tank to pour water. When the water outlet nozzle 7 is connected to a drain pipe communicating with the outside of the room, water is discharged to the outside of the room through the water outlet nozzle 7 and the drain pipe. Wherein the nozzle 7 may be threaded to facilitate connection to standard garden water pipes.

The above description is only for the specific embodiments of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art can easily conceive of the changes or substitutions within the technical scope of the present invention, and all the changes or substitutions should be covered within the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the appended claims.
