[0038] In addition, the terms “first”, “second”, etc., if used, are merely used to distinguish between the descriptions and should not be understood as indicating or implying relative importance.

[0039] It should be noted that, in the absence of conflict, the features in the embodiments of the present invention may be combined with each other.

[0040] Dehumidifiers are used to adjust air humidity to keep it within a comfortable range. During the operation of dehumidifiers, sensors play a vital role. Current dehumidifier sensors are usually located in the electrical control box or other locations near the top of the water tank, which not only makes the sensor susceptible to moisture, but also affects the sensor's detection accuracy.

[0041] Based on the above questions, please refer to Figures 1 to 4 An embodiment of the present invention provides a dehumidifier 10, which includes a water tank 100, a middle partition 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 throttle (not shown).

[0042] Among them, a middle partition 200 is arranged in the outer shell 300, a water receiving tray is arranged above the middle partition 200, an evaporator 800 and a condenser 700 are fixedly arranged above the water receiving tray, a water tank 100 is accommodated in the lower part of the middle partition 200, and a mounting portion 210 is arranged on at least one side plate of the middle partition 200 located on both sides of the water tank 100, and an air quality sensor 400 is detachably mounted on the mounting portion 210.

[0043] Specifically, the housing 300 includes a front housing 310 and a rear housing 320. The front housing 310 and the rear housing 320 are connected and together with the top cover plate 900, they surround the water tank 100, the fan 500, the compressor 600, the condenser 700, the evaporator 800, and the throttle, etc., to form the housing of the dehumidifier 10 and play a protective role. The evaporator 800, the condenser 700, and the fan 500 are arranged in sequence, and the air flows through the evaporator 800, the condenser 700, and the fan 500 in sequence from the air inlet of the rear housing 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 accommodated below the middle partition plate 200. The water tank 100 is used to receive the condensed water generated during the dehumidification process.

[0044] It is understandable 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 in a high-temperature and high-pressure state under the compression of the compressor 600, and the high-temperature and high-pressure heat exchange medium is cooled down 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 transfers heat between the evaporator 800 and the air introduced by the fan 500, that is, the heat exchange medium absorbs heat to condense the moisture in the air, thereby achieving the purpose of dehumidification. In this process, the heat exchange medium is converted from liquid to low-pressure gas and flows to the compressor 600 again, and circulates through the above-mentioned path.

[0045] It should also be noted that the middle partition 200 is arranged between the outer shell 300 and the water tank 100, and the air quality sensor 400 is arranged on the middle partition 200. The air quality sensor 400 can be a temperature sensor or a humidity sensor, and of course it can also be an integrated temperature and humidity sensor.

[0046] Specifically, the middle partition 200 is vertically arranged on the side wall of the water tank 100, and the middle partition 200 is provided with a mounting portion 210. The air quality sensor 400 is snap-fitted with the mounting portion 210 to realize that the air quality sensor 400 can be detachably installed on the middle partition 200, thereby improving the installation or disassembly efficiency and ensuring that the air quality sensor 400 is installed stably; the top opening of the middle partition 200 is provided with a water receiving tray, so the air quality sensor 400 installed on the middle partition 200 is located on one side of the water receiving tray of the water tank 100, so that the air quality sensor 400 is prevented from moisture, thereby improving the detection accuracy of the air quality sensor 400 and extending the service life of the air quality sensor 400.

[0047] The outer shell 300 is arranged outside the middle partition 200. In detail, at least a portion of the front shell 310 is arranged on the outside of the middle partition 200 away from the water tank 100, and a vent 311 is opened on the side wall of the front shell 310 corresponding to the mounting portion 210 to supply air to the mounting portion 210 through the vent 311, thereby further preventing the air quality sensor 400 from getting damp and improving the detection accuracy of the air quality sensor 400.

[0048] Furthermore, the vent hole 311 is arranged opposite to the mounting portion 210 to ensure that the air flows through the temperature and humidity sensor through the vent hole 311 under the action of negative pressure. In other words, the projection of the portion of the front enclosure 310 where the vent hole 311 is provided on the middle partition 200 at least partially overlaps with the mounting portion 210, so as to realize air supply directly 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 from the vent hole 311 under the action of negative pressure, thereby preventing the air quality sensor 400 from getting damp, further improving the detection accuracy of the air quality sensor 400, and thus improving the service life. In addition, by arranging the air quality sensor 400 on the middle partition 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 with by signals.

[0049] Furthermore, the number of the ventilation holes 311 includes a plurality, and the plurality of ventilation holes 311 are arranged in an array, and the peripheries of the plurality of ventilation holes 311 are distributed in a circular shape.

[0050] In this embodiment, a plurality of ventilation holes 311 are evenly and circularly distributed on the front shell 310, which can increase the air intake volume, thereby preventing the air quality sensor 400 from getting damp and also preventing dust accumulation.

[0051] Furthermore, the mounting portion 210 includes a plurality of limiting portions 211 , and the plurality of limiting portions 211 enclose a mounting area 212 . A buckle 213 is provided on a side of at least one limiting portion 211 facing the mounting area 212 , and the buckle 213 is snap-fitted with the air quality sensor 400 .

[0052] In this embodiment, the air quality sensor 400 is limited by multiple limiting portions 211 to confine it to the installation area 212; a buckle 213 is provided on at least one limiting portion 211 and is engaged with the air quality sensor 400 to fix the air quality sensor 400, thereby facilitating the installation or disassembly of the air quality sensor 400.

[0053] Furthermore, the plurality of limiting portions 211 include a first limiting portion 2111, a second limiting portion 2112 and a third limiting portion 2113, and the first limiting portion 2111, the second limiting portion 2112 and the third limiting portion 2113 are connected in sequence and are U-shaped to enclose the installation area 212. In other words, the end of the first limiting portion 2111 away from the second limiting portion 2112 is spaced 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 perpendicular to the second limiting portion 2112 to enclose a rectangular installation area 212 to match the shape of the air quality sensor 400. Of course, it is not limited to this. 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 no specific limitation is made here.

[0055] Therefore, the air quality sensor 400 is limited in the planar direction of the plane where the middle partition plate 200 is located by the first limiting portion 2111, the second limiting portion 2112 and the third limiting portion 2113, and a buckle 213 is provided on at least one of the first limiting portion 2111, the second limiting portion 2112 and the third limiting portion 2113, so that the limiting portion 211 is snap-fitted with the air quality sensor 400, thereby achieving the purpose of fixing the air quality sensor 400 and facilitating the installation or disassembly of the air quality sensor 400.

[0056] Furthermore, both 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 provided with buckles 213 , and the buckles 213 are staggered.

[0057] In this embodiment, the buckles 213 on the first limiting portion 2111 and the third limiting portion 2113 are simultaneously engaged with the edges on both sides of the air quality sensor 400, so that the air quality sensor 400 is firmly engaged on the mounting portion 210, thereby improving the installation stability of the air quality sensor 400.

[0058] The buckle 213 located at the first limiting portion 2111 and the buckle 213 located at the third limiting portion 2113 are staggered, and the extension length of the third limiting portion 2113 is smaller than the extension length of the first limiting portion 2111, thereby simplifying the mold structure and improving the molding efficiency of the mounting portion 210.

[0059] Also, see Figure 5In other embodiments of the present invention, the buckle 213 located at the first limiting portion 2111 and the buckle 213 located at the second limiting portion 2112 can also be arranged relative to each other, which can also make the air quality sensor 400 firmly connected to the mounting portion 210, thereby improving the installation stability of the air quality sensor 400.

[0060] Specifically, the buckle 213 is provided with an inclined guide surface, so that the air quality sensor 400 can be engaged with the buckle 213 under the guidance of the guide surface.

[0061] Furthermore, a fourth limiting portion 2114 is protruded from the second limiting portion 2112 toward the installation 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 middle partition plate 200 .

[0062] In this embodiment, the fourth limiting portion 2114 is used to abut against the side of the air quality sensor 400 away from the middle partition 200, so as to limit the air quality sensor 400 in a direction perpendicular to the plane where the middle partition 200 is located, so as to prevent the air quality sensor 400 from detaching from the mounting portion 210, thereby further improving the installation stability of the air quality sensor 400.

[0063] Furthermore, a positioning column 214 is protrudingly provided in the installation area 212 , and a positioning hole 410 is opened in the air quality sensor 400 . The positioning column 214 is used to penetrate the positioning hole 410 .

[0064] In this embodiment, during the installation process, the positioning hole 410 provided on the air quality sensor 400 is aligned with the positioning mark and the positioning column 214 passes through the positioning hole 410 to position the air quality sensor 400 and ensure that the air quality sensor 400 is installed correctly.

[0065] Furthermore, a support portion 215 is protruded in the installation area 212, and the support portion 215 is used to abut against the air quality sensor 400 so that the air quality sensor 400 is slightly raised relative to the middle partition 200 to prevent condensation on the outer wall of the middle partition 200 or deformation of the middle partition 200 from affecting the air quality sensor 400.

[0066] In this embodiment, the support portion 215 is connected to the limit portion 211. The support portion 215 allows the air quality sensor 400 to be spaced from the middle partition plate 200, which is not only convenient for wiring, but also prevents the air quality sensor 400 from contacting water when water flows down the middle partition plate 200.

[0067] Furthermore, the installation portion 210 is further provided with a wiring portion 216 , which is located outside the installation area 212 and spaced apart from the middle partition plate 200 .

[0068] In this embodiment, a main control box 218 is installed on the middle partition 200, and the end of the wiring portion 216 extends in the direction of the main control box 218. In other words, the wiring portion 216 is connected to the third limiting portion 2113 and extends in the horizontal direction away from the installation area 212. The wiring portion 216 is spaced apart from the middle partition 200 to limit the cable 219, so that the cable 219 is routed reasonably. In addition, the wiring portion 216 can connect the cable 219 to the main control box 218, and the cable 219 between the air quality sensor 400 and the main control box 218 is placed in a U shape, so that condensed water is generated on the cable 219, so that the condensed water flows down along the lowest point of the U shape of the cable 219, avoiding water droplets from flowing to the electrical components, and causing the air quality sensor 400 to be damp, thereby avoiding affecting the detection accuracy of the air quality sensor 400.

[0069] In addition, a reinforcing rib 2161 is integrally formed on the outer wall of the wiring portion 216 to enhance the structural strength of the wiring portion 216 .

[0070] Specifically, the second limiting portion 2112 is further provided with a wiring hole 217 communicating with the installation area 212 , so that the cable 219 can be connected to the air quality sensor 400 through the wiring hole 217 .

[0071] Furthermore, a recessed portion 2115 is formed on a side wall of at least one limiting portion 211 facing the installation area 212 .

[0072] In this embodiment, the recessed portion 2115 is in the shape of an arc-shaped groove and is disposed on the side wall of the third limiting portion 2113 facing the installation area 212, and the recessed portion 2115 is disposed adjacent to the buckle 213. By providing the recessed portion 2115, when the air quality sensor 400 is disassembled, it is convenient for the operator to insert the finger into the recessed portion 2115 and apply a force to push the air quality sensor 400, so that the air quality sensor 400 and the buckle 213 are out of the clamping state, thereby improving the convenience of disassembling the air quality sensor 400.

[0073] Finally, it should be noted that during the installation process, first, the top end of the air quality sensor 400 is placed between the fourth limiting portion 2114 and the middle partition 200, so that the air quality sensor 400 forms an angle with the middle partition 200; then, the air quality sensor 400 is clamped into the end of the fourth limiting portion 2114 and rotated, so that the positioning hole 410 on the air quality sensor 400 is aligned with the positioning column 214, so that 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 respectively clamped into the buckle 213 of the first limiting portion 2111 and the third limiting portion 2113, thereby completing the installation of the air quality sensor 400.

[0074] During the disassembly process, first, the air quality sensor 400 is disengaged from the snap fit state with the first limiting portion 2111 and the third limiting portion 2113, and the air quality sensor 400 is rotated around its top to disengage the positioning hole 410 from the positioning column 214, and finally, the end of the air quality sensor 400 is removed from between the fourth limiting portion 2114 and the middle partition 200.

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