[0035] In the description of the present invention, "plurality" means two or more than two, and "several" means one or more.

[0036] The following describes a dehumidifier 1 according to an embodiment of the present invention with reference to the accompanying drawings.

[0037] like Figure 2-Figure 4 As shown, the dehumidifier 1 according to the embodiment of the present invention includes a housing 100 , a fan (not shown in the figure), an evaporator 200 , a water storage device 300 , a water pump (not shown in the figure), and a filter 400 .

[0038] The housing 100 is provided with an air inlet 110 and an air outlet (not shown in the figure). The fan, evaporator 200, water storage device 300 and water pump are arranged in the housing 100. The evaporator 200 is adjacent to the air inlet 110. The fan is used to suck the outside air from the air inlet 110 into the housing 100 and discharge it from the air outlet after passing through the evaporator 200. The water storage device 300 is arranged below the evaporator 200 and is used to receive the condensed water generated by the evaporator 200. The water pump is connected to the water storage device 300 and forms a drainage waterway. The filter 400 is arranged in the drainage waterway and is used to filter the condensed water, that is, the condensed water flows through the filter 400 and enters the water pump, and the filter 400 is exposed from the air inlet 110, for example, the upper part of the filter 400 is exposed from the air inlet 110.

[0039] According to the dehumidifier 1 of the embodiment of the present invention, a water storage device 300 is provided for receiving condensed water generated by the evaporator 200, and the water pump is connected to the water storage device 300 to form a drainage waterway, and a filter 400 is provided in the drainage waterway, so that the condensed water first passes through the filter 400 and is then discharged from the housing 100 by the water pump. In this way, the filter 400 is provided to increase the filtering effect of impurities in the condensed water and prevent the water pump from being blocked.

[0040] Furthermore, the filter 400 is exposed from the air inlet 110, and the user can disassemble and assemble the filter 400 through the air inlet 110, which improves the convenience of disassembling and assembling the filter 400. Since the filter 400 is easy to disassemble and assemble, it is also convenient for the user to clean, replace and maintain it, reducing the probability of impurities accumulating at the filter 400, and further reducing the probability of the water pump being blocked.

[0041] Thus, the dehumidifier 1 according to the embodiment of the present invention has the advantages of convenient disassembly and assembly of the water filter and easy maintenance.

[0042] According to some specific embodiments of the present invention, Figure 2 and Figure 3 As shown, the filter 400 is located on the side of the evaporator 200 facing the air inlet 110. The evaporator 200 is arranged corresponding to the air inlet 110, and in the thickness direction (front-back direction) of the dehumidifier 1, the filter 400 is located between the evaporator 200 and the air inlet 110. This makes it easier for users to observe and hold, and further improves the convenience of replacing and cleaning the filter 400.

[0043] According to some specific embodiments of the present invention, Figure 2 As shown, part of the filter 400 (for example, the upper part of the filter 400) is exposed from the lower edge of the air inlet 110. In the up-down direction, most of the filter 400 is arranged below the air inlet 110. This further facilitates the user to observe and hold, and further improves the convenience of replacing and cleaning the filter 400.

[0044] According to some specific embodiments of the present invention, Figure 1 and Figure 2 As shown, the dehumidifier 1 further includes an air filter 500 , which is detachably mounted at the air inlet 110 of the housing 100 and blocks a portion of the filter 400 that is exposed from the air inlet 110 (eg, an upper portion of the filter 400 ).

[0045] By setting the air filter 500, the filter 400 can be shielded to improve the aesthetics of the dehumidifier 1, and the air passing through the air inlet 110 can be pre-filtered to effectively reduce the number and volume of impurities in the condensed water. Figure 2 As shown, after the air filter 500 of the dehumidifier 1 is removed, the filter 400 can be easily observed and plugged in and out from the air inlet 110 .

[0046] In addition, since the filter 400 can be observed by removing the air filter 500, the user can be reminded to clean the filter 400 when the user cleans the air filter 500. At the same time, when the filter 400 needs to be cleaned, the air filter 500 must also be removed, which also achieves the effect of reminding the user to clean the air filter 500.

[0047] According to some specific embodiments of the present invention, Figure 5 and Figure 6 As shown, the water storage device 300 includes a water storage pan 320 . The water storage pan 320 is disposed below the evaporator 200 . The water storage pan 320 is provided with guide ribs 330 . The guide ribs 330 define a water channel 340 in the water storage cavity 321 .

[0048] like Figure 8 As shown, the water channel 340 includes an inlet section 341, an intermediate section 342 and an outlet section 343. The intermediate section 342 is connected to the inlet section 341 and the outlet section 343 respectively. The inlet section 341 is used to collect condensed water generated by the evaporator 200. The water pump is connected to the outlet section 343. There is at least one filter screen 400 and it is vertically installed between the inlet section 341 and the intermediate section 342 and / or between the outlet section 343 and the intermediate section 342. A portion of each filter screen 400 (for example, the upper portion of the filter screen 400) is exposed from the water storage tray 320.

[0049] Specifically, the guide rib 330 includes a first sub-guide rib 331, a second sub-guide rib 332 and a third sub-guide rib 333. The first sub-guide rib 331 separates the water inlet section 341 and the water outlet section 343, the second sub-guide rib 332 separates the water inlet section 341 and the middle section 342, and the third sub-guide rib 333 separates the water outlet section 343 and the middle section 342.

[0050] In some embodiments of the present invention, Figure 8 As shown, there are multiple filter screens 400, which are arranged in series on the water channel 340, at least one filter screen 400 is arranged on the second sub-guiding rib 332 and connects the water inlet section 341 and the middle section 342, and at least one filter screen 400 is arranged on the third sub-guiding rib 333 and connects the middle section 342 and the water outlet section 343. By arranging multiple filter screens 400 arranged in series, impurities in the condensed water flowing into the water pump can be effectively reduced.

[0051] The water channel 340 is defined by the arrangement of the guide ribs 330, that is, the flow direction of the condensed water in the water storage tray 320 is determined, which facilitates the filtering of the condensed water. In addition, by arranging at least a portion of the filter net 400 in the water channel 340, the condensed water can be filtered by the filter net 400.

[0052] In addition, the first sub-guide rib 331, the second sub-guide rib 332 and the third sub-guide rib 333 are provided to guide the flow direction of the condensed water and separate the condensed water in the water inlet section 341, the middle section 342 and the water outlet section 343 to prevent the condensed water in the water inlet section 341, the middle section 342 and the water outlet section 343 from mixing with each other.

[0053] In addition, a water tank (not shown in the figure) can be provided under the water storage tray 320, so that when the water pump is not started or the filter 400 is clogged due to not being cleaned for a long time, the condensed water in the water storage tray 320 can overflow into the water tank, thereby improving the safety of the dehumidifier 1.

[0054] According to some specific embodiments of the present invention, Figure 8 As shown, the water inlet section 341 includes a first section 345 and a second section 346, the water outlet section 343 includes a third section 347 and a fourth section 348, the second section 346, the middle section 342 and the third section 347 all extend along the length direction of the water storage tray 320, the first section 345 and the fourth section 348 all extend along the width direction of the water storage tray 320, and the second section 346 and the third section 347 are arranged along the length direction of the water storage tray 320.

[0055] The middle section 342 is located on one side of the second section 346 and the third section 347 in the width direction of the water storage tray 320 , and is located between the first section 345 and the fourth section 348 in the length direction of the water storage tray 320 .

[0056] For example, the first section 345 and the second section 346 are connected to form an L shape, the third section 347 and the fourth section 348 are connected to form an L shape, and the second section 346 and the third section 347 also have a flow path turning point with the middle section 342. In this way, the flow rate of the condensed water can be reduced at the turning point of the water channel 340 to prevent the condensed water from flowing too fast and impacting the filter 400 and the water pump. At the same time, reducing the flow rate of the condensed water can also increase the filtering effect of the filter 400 on the condensed water.

[0057] The second section 346 and the third section 347 are arranged along the length direction of the water storage tray 320, and the middle section 342 is located on one side of the second section 346 and the third section 347 in the width direction of the water storage tray 320. This can improve the space utilization of the dehumidifier 1 while ensuring the water storage volume of the water storage tray 320.

[0058] According to some specific embodiments of the present invention, Figure 3 , Figure 4 and Figure 7 As shown, the water storage device 300 further includes a water receiving tray 310. The water receiving tray 310 is installed on the evaporator 200 and is located below the evaporator 200. The water receiving tray 310 has a water outlet 311 connected to the water inlet section 341. The water receiving tray 310 is used to receive the condensed water generated by the evaporator 200 and transport it to the water inlet section 341 through the water outlet 311. A portion of each filter screen 400 (for example, the upper portion of the filter screen 400) is exposed from the water receiving tray 310.

[0059] In other words, the water receiving pan 310 is located between the water storage pan 320 and the evaporator 200, and the compressor 220 is located on the side of the water storage pan 320 facing away from the water receiving pan 310. The water storage pan 320 is used to collect condensed water generated by the evaporator 200, and the water receiving pan 310 is used to guide the condensed water generated by the evaporator 200 into the water storage pan 320, thereby improving the collection efficiency of condensed water.

[0060] By splitting the water storage device 300 into a water receiving tray 310 and a water storage tray 320, not only is it convenient to produce, process and model the water receiving tray 310 and the water storage tray 320, but it can also increase the water storage volume of the water storage device 300, thereby improving the space utilization of the dehumidifier 1 and facilitating cleaning.

[0061] According to some specific embodiments of the present invention, Figure 2-Figure 5 As shown, the portion of the filter screen 400 exposed from the water receiving tray 310 is configured with an outer flange 410 .

[0062] Specifically, the outer flange 410 is bent toward one side in the thickness direction of the filter 400. For example, the outer flange 410 is bent toward the direction of the air inlet 110. This not only facilitates user observation, but also provides the user with a better gripping position, further facilitating the insertion and removal of the filter 400, and preventing difficulties in insertion and removal caused by water droplets on the surface of the filter 400.

[0063] For example, the outer flange 410 may not be provided with mesh holes, so as to increase the structural strength of the outer flange 410 and prevent the outer flange 410 from being damaged due to force during insertion and removal.

[0064] According to some specific embodiments of the present invention, Figure 3 , Figure 6 and Figure 7 As shown, the water storage tray 320 is provided with a slot 322 , the water receiving tray 310 is provided with a socket 312 corresponding to the position of the slot 322 , and the filter screen 400 is pluggable and matched with the slot 322 and the socket 312 .

[0065] For example, the width of the slot 322 is the same as the width of the socket 312. The arrangement of the slot 322 not only ensures the connection strength between the water storage tray 320 and the filter 400, but also ensures the convenience of disassembly and assembly of the filter 400, that is, ensures the convenience of cleaning and replacement of the filter 400.

[0066] Since the slot 322 is arranged in the water storage tray 320, and the water receiving tray 310 is located between the water storage tray 320 and the evaporator 200, that is, the water receiving tray 310 may block the slot 322, the setting of the socket 312 can provide guidance for the insertion of the filter 400, and the filter 400 can be introduced into the slot 322, thereby increasing the convenience of plugging and unplugging the filter 400.

[0067] Furthermore, by providing the socket 312 , the connection and fixing strength between the filter 400 and the water storage device 300 is increased, the probability of collision between the filter 400 and other components of the dehumidifier 1 is reduced, and the safety of the dehumidifier 1 is improved.

[0068] In some embodiments of the present invention, Figure 6 and Figure 8 As shown, the slots 322 are respectively constructed on the second sub-guiding ribs 332 and the third sub-guiding ribs 333, and the two sides of the filter 400 in the width direction are matched with the slots 322. In addition, there are multiple slots 322 and sockets 312, and multiple filter nets 400, multiple slots 322 and multiple sockets 312 correspond to each other.

[0069] Other components of the dehumidifier 1 according to the embodiment of the present invention are known to those skilled in the art and will not be described in detail here.
