[0039] It should be noted that the features in the embodiments of the application can be combined with each other without conflict.

[0040] The dehumidifier is used to adjust the air humidity so that the air humidity is maintained within a comfortable humidity range. During the operation of the dehumidifier, the sensor plays a crucial role. The sensor of the current dehumidifier is usually arranged in an electric control box or other positions close to the top of the water tank, which not only makes the sensor prone to moisture, but also affects the detection accuracy of the sensor.

[0041] Based on the above problems, please refer to Figures 1 to 4 The embodiment of the application provides a dehumidifier 10, which comprises a water tank 100, a partition plate 200, a shell 300, an air quality sensor 400, a fan 500, a compressor 600, a condenser 700, an evaporator 800, a top cover plate 900 and a throttler (not shown in the figure).

[0042] The shell 300 is provided with the partition plate 200, a water receiving tray is arranged above the partition plate 200, the evaporator 800 and the condenser 700 are fixedly arranged above the water receiving tray, the water tank 100 is arranged in the lower part of the partition plate 200, the mounting part 210 is arranged on at least one side plate of the partition plate 200, and the air quality sensor 400 is detachably mounted on the mounting part 210.

[0043] Specifically, the shell 300 comprises a front wall 310 and a rear wall 320, the front wall 310 and the rear wall 320 are connected and jointly enclose the water tank 100, the fan 500, the compressor 600, the condenser 700, the evaporator 800 and the throttling device, etc. outside to form the shell of the dehumidifier 10 and play a protective role. The evaporator 800, the condenser 700 and the fan 500 are sequentially arranged, air flows through the evaporator 800, the condenser 700 and the fan 500 in sequence from the air inlet of the rear wall 320, and is discharged from the air outlet of the top cover plate 900. The water tank 100 is arranged at the bottom of the evaporator 800, the condenser 700 and the fan 500, and is contained below the partition plate 200, and the water tank 100 is used to receive the condensed water generated in the dehumidification process.

[0044] It can be understood that the dehumidifier 10 is also provided with a heat exchange medium, which can be, but is not limited to, a refrigerant. The heat exchange medium first flows to the condenser 700 under the compression of the compressor 600 in a high-temperature and high-pressure state, and the high-temperature and high-pressure heat exchange medium is cooled to form a low-temperature and high-pressure liquid under the action of the condenser 700, and then passes through the throttling device to form a low-temperature and low-pressure liquid. The heat exchange medium then flows to the evaporator 800, and the low-temperature and low-pressure liquid heat exchange medium performs heat transfer with the air introduced by the fan 500 in the evaporator 800, that is, absorbs heat through the heat exchange medium to condense the moisture in the air, so as to achieve the purpose of dehumidification. In this process, the heat exchange medium is converted from a liquid to a low-pressure gas and flows to the compressor 600 again and circulates through the above-mentioned path.

[0045] In addition, it should be noted that the partition plate 200 is arranged between the shell 300 and the water tank 100, and the air quality sensor 400 is arranged on the partition plate 200. The air quality sensor 400 can be a temperature sensor, a humidity sensor, or a temperature and humidity sensor integrated as one.

[0046] Specifically, the partition plate 200 is vertically arranged on the side wall of the water tank 100, and the partition plate 200 is provided with a mounting portion 210. The air quality sensor 400 is detachably mounted on the partition plate 200 in a clamping manner with the mounting portion 210, so as to improve the installation or dismounting efficiency and ensure the stable installation of the air quality sensor 400. The top opening of the partition plate 200 is provided with a water pan, so that the air quality sensor 400 mounted on the partition plate 200 is located on one side of the water pan of the water tank 100, so that the air quality sensor 400 is prevented from being damp, thereby improving the detection accuracy of the air quality sensor 400 and prolonging the service life of the air quality sensor 400.

[0047] The shell 300 is arranged outside the partition plate 200, specifically, at least part of the front shell 310 is arranged outside the partition plate 200 away from the water tank 100, and the side wall of the front shell 310 corresponding to the mounting portion 210 is provided with an air permeable hole 311 to send air to the mounting portion 210 through the air permeable hole 311, further to avoid the air quality sensor 400 from being damp, and improve the detection accuracy of the air quality sensor 400.

[0048] Further, the air permeable hole 311 is arranged opposite to the mounting portion 210, to ensure that the air flows through the air permeable hole 311 under the action of negative pressure. In other words, the projection of the part of the front shell 310 provided with the air permeable hole 311 on the partition plate 200 at least partially overlaps with the mounting portion 210, to realize air supply to the air quality sensor 400 mounted on the mounting portion 210, so that the cold air flows through the air quality sensor 400 and the evaporator 800 in sequence under the action of negative pressure from the air permeable hole 311, to avoid the air quality sensor 400 from being damp, further to improve the detection accuracy of the air quality sensor 400, and thus to improve the service life. Moreover, by arranging the air quality sensor 400 on the partition plate 200 on one side of the water tank 100, the internal wiring can be shortened, and the air quality sensor 400 can be prevented from being interfered by signals.

[0049] Further, the air permeable hole 311 includes a plurality of air permeable holes 311, and the plurality of air permeable holes 311 are arranged in an array, and the periphery of the plurality of air permeable holes 311 is circularly distributed.

[0050] In the embodiment, the plurality of air permeable holes 311 are uniformly and circularly distributed on the front shell 310, to improve the air intake, to avoid the air quality sensor 400 from being damp, and also to avoid dust accumulation.

[0051] Further, the mounting portion 210 includes a plurality of limiting portions 211, the plurality of limiting portions 211 enclose a mounting area 212, at least one limiting portion 211 is provided with a buckle 213 on the side facing the mounting area 212, and the buckle 213 is in clamping connection with the air quality sensor 400.

[0052] In the embodiment, the air quality sensor 400 is limited in the mounting area 212 by the plurality of limiting portions 211, and the air quality sensor 400 is fixed by the buckle 213 on at least one limiting portion 211 in clamping connection, to facilitate the installation or disassembly of the air quality sensor 400.

[0053] Further, the plurality of limiting portions 211 include a first limiting portion 2111, a second limiting portion 2112, and a third limiting portion 2113, which are connected in sequence and in a U-shaped form to enclose the mounting area 212. In other words, the end of the first limiting portion 2111 away from the second limiting portion 2112 is arranged apart from the end of the third limiting portion 2113 away from the second limiting portion 2112.

[0054] In this embodiment, the first limiting portion 2111 and the third limiting portion 2113 are arranged in parallel and are both arranged perpendicularly to the second limiting portion 2112 to enclose the mounting area 212 in a rectangular form, so as to match the shape of the air quality sensor 400. Of course, the first limiting portion 2111, the second limiting portion 2112, and the third limiting portion 2113 can be adjusted according to the actual shape of the air quality sensor 400, and are not specifically limited herein.

[0055] Therefore, the air quality sensor 400 is limited in the planar direction of the plane where the baffle 200 is located by the first limiting portion 2111, the second limiting portion 2112, and the third limiting portion 2113, and the limiting portion 211 is clamped and matched with the air quality sensor 400 by the buckle 213 arranged in at least one of the first limiting portion 2111, the second limiting portion 2112, and the third limiting portion 2113, so as to achieve the purpose of fixing the air quality sensor 400 and facilitate the installation or disassembly of the air quality sensor 400.

[0056] Further, the end of the first limiting portion 2111 away from the second limiting portion 2112 and the end of the third limiting portion 2113 away from the second limiting portion 2112 are both provided with the buckle 213, which is arranged in a staggered manner.

[0057] In this embodiment, the buckle 213 on the first limiting portion 2111 and the buckle 213 on the third limiting portion 2113 are clamped and matched with the edges on both sides of the air quality sensor 400 at the same time, so as to stably clamp the air quality sensor 400 on the mounting portion 210, thereby improving the installation stability of the air quality sensor 400.

[0058] The buckle 213 on the first limiting portion 2111 and the buckle 213 on the third limiting portion 2113 are arranged in a staggered manner, and the extension length of the third limiting portion 2113 is less than the extension length of the first limiting portion 2111, so as to simplify the mold structure and improve the forming efficiency of the mounting portion 210.

[0059] In addition, please refer to Figure 5In other embodiments of the present application, the buckle 213 located at the first limiting portion 2111 and the buckle 213 located at the second limiting portion 2112 are oppositely arranged, which can also stably clamp the air quality sensor 400 on the mounting portion 210, thereby improving the mounting stability of the air quality sensor 400.

[0060] Specifically, the buckle 213 is provided with an inclined guide surface, so as to facilitate the air quality sensor 400 to be clamped and matched with the buckle 213 under the guidance of the guide surface.

[0061] Further, the second limiting portion 2112 is provided with a fourth limiting portion 2114 in the direction of the mounting area 212, and the fourth limiting portion 2114 is used to limit the air quality sensor 400 between the fourth limiting portion 2114 and the partition plate 200.

[0062] In the present embodiment, the fourth limiting portion 2114 is used to abut against the side of the air quality sensor 400 away from the partition plate 200, so as to limit the air quality sensor 400 in the direction perpendicular to the plane of the partition plate 200, thereby avoiding the air quality sensor 400 from being separated from the mounting portion 210, and further improving the mounting stability of the air quality sensor 400.

[0063] Further, the mounting area 212 is provided with a positioning column 214, and the air quality sensor 400 is provided with a positioning hole 410, and the positioning column 214 is used to pass through the positioning hole 410.

[0064] In the present embodiment, during the mounting process, the positioning hole 410 provided on the air quality sensor 400 is aligned with the positioning column 214, and the positioning column 214 passes through the positioning hole 410, so as to position the air quality sensor 400, and ensure that the air quality sensor 400 is mounted correctly.

[0065] Further, the mounting area 212 is also provided with a supporting portion 215, and the supporting portion 215 is used to abut against the air quality sensor 400, so as to slightly raise the air quality sensor 400 relative to the partition plate 200, thereby preventing the influence of condensation on the outer wall of the partition plate 200 or deformation of the partition plate 200 on the air quality sensor 400.

[0066] In the present embodiment, the supporting portion 215 is connected with the limiting portion 211. The air quality sensor 400 is spaced apart from the partition plate 200 by the supporting portion 215, which not only facilitates wiring, but also avoids the air quality sensor 400 from being in contact with water in the case that water flows on the partition plate 200.

[0067] Further, the mounting portion 210 is also provided with a wiring portion 216, and the wiring portion 216 is located outside the mounting area 212 and is spaced apart from the partition plate 200.

[0068] In the embodiment, the main control box 218 is installed on the partition plate 200, and the end of the wire arrangement part 216 extends in the direction of the main control box 218, in other words, the wire arrangement part 216 is connected with the third limiting part 2113 and extends in the horizontal direction away from the installation area 212, and the wire arrangement part 216 is spaced apart from the partition plate 200 to facilitate limiting the cable 219, so that the cable 219 is reasonably arranged. In addition, the cable 219 can be connected to the main control box 218 through the wire arrangement part 216, and the cable 219 between the air quality sensor 400 and the main control box 218 is arranged in a U shape, so that in the case of condensate water on the cable 219, the condensate water flows down along the lowest point of the U shape of the cable 219, avoiding the water droplets flowing to the electrical elements, and can cause the air quality sensor 400 to be damp, thereby avoiding affecting the detection accuracy of the air quality sensor 400.

[0069] In addition, the outer wall of the wire arrangement part 216 is integrally formed with a reinforcing rib 2161 to strengthen the structural strength of the wire arrangement part 216.

[0070] Specifically, the second limiting part 2112 is further provided with a wire arrangement hole 217 communicating with the installation area 212, so that the cable 219 is connected with the air quality sensor 400 through the wire arrangement hole 217.

[0071] Further, at least one limiting part 211 is recessed with a recessed part 2115 on the side wall facing the installation area 212.

[0072] In the embodiment, the recessed part 2115 is in the form of an arc-shaped groove, and is arranged on the side wall of the third limiting part 2113 facing the installation area 212, and the recessed part 2115 is arranged adjacent to the buckle 213. By arranging the recessed part 2115, in the case of disassembling the air quality sensor 400, the fingers of the operator can be inserted into the recessed part 2115 and an acting force is applied to release the air quality sensor 400, so that the air quality sensor 400 is disengaged from the buckling state with the buckle 213, thereby improving the convenience of disassembling the air quality sensor 400.

[0073] Finally, it should be noted that in the installation process, first, the top end of the air quality sensor 400 is arranged between the fourth limiting part 2114 and the partition plate 200, so that the air quality sensor 400 and the partition plate 200 form an angle; then the air quality sensor 400 is buckled into the end of the fourth limiting part 2114 to rotate, so that the positioning hole 410 on the air quality sensor 400 is aligned with the positioning column 214, and the positioning column 214 is inserted into the positioning hole 410; at the same time, the other end of the air quality sensor 400 is buckled into the buckle 213 of the first limiting part 2111 and the third limiting part 2113, respectively, to complete the installation of the air quality sensor 400.

[0074] In the process of disassembling, first, the air quality sensor 400 is disengaged from the snap-fit state with the first limiting portion 2111 and the buckle 213 of the third limiting portion 2113, and the air quality sensor 400 is rotated around the top portion to disengage the positioning hole 410 from the positioning column 214, and finally the end of the air quality sensor 400 is taken out from between the fourth limiting portion 2114 and the partition plate 200.

[0075] In summary, the embodiment of the present application provides a dehumidifier 10, by setting the mounting portion 210 on the partition plate 200, the air quality sensor 400 is snap-fitted with the mounting portion 210, so that the air quality sensor 400 is detachably mounted on the partition plate 200, improving the installation or disassembly efficiency, while ensuring the stable installation of the air quality sensor 400; the partition plate 200 is located on the side wall of the water tank 100, and the air quality sensor 400 is prevented from being damp, thereby improving the detection accuracy of the air quality sensor 400 and prolonging the service life of the air quality sensor 400; in addition, the air hole 311 is provided on the shell 300 corresponding to the mounting portion 210, so that air is supplied to the air quality sensor 400 through the air hole 311, further preventing the air quality sensor 400 from being damp, and improving the detection accuracy of the air quality sensor 400.
