[0062] In order to make the purposes, technical solutions and advantages of the present application clearer, the present application will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only intended to explain the present application and not to limit the present application.

[0063] The inventor found that there is a certain space in the base of the clothes treatment equipment for storing water in order to recycle the water inside the clothes treatment equipment. Part of the space for storing water is formed by splicing multiple plate bodies, and the splicing part of the two plate bodies needs to be sealed. These sealing structures will occupy a certain space, making it difficult to reduce the size of the clothes treatment equipment, and when the sealing is not proper, there is also a risk of water leakage. Based on this, the embodiments of the present application provide a clothes treatment equipment, which improves the sealing structure at the water collecting cavity of the clothes treatment equipment.

[0064] As shown in Figure 1 , it is a partial structure schematic diagram of the clothes treatment equipment according to an embodiment of the present application. The clothes treatment equipment includes a base assembly. As shown in Figure 2 , it is a cross-sectional structure schematic diagram of the base assembly according to an embodiment of the present application. The base assembly includes a base 110 and a water pump cover plate 120. The water pump cover plate 120 is installed on the base 110, and the water pump cover plate 120 and the base 110 enclose a water collecting cavity 101. The water collecting cavity 101 can receive and store water discharged from other channels of the clothes treatment equipment.

[0065] In combination with Figure 3 and Figure 4 , the clothes treatment equipment further includes a first sealing ring 300. The first sealing ring 300 is clamped between the water pump cover plate 120 and the base 110 to seal the gap between the water pump cover plate 120 and the base 110. Specifically, the water pump cover plate 120 has a first surface 1211 and a second surface 1212 facing the base 110, and the first surface 1211 and the second surface 1212 are arranged at an angle, that is, the angle between the first surface 1211 and the second surface 1212 is α, 0° < α ≤ 90°, for example, α is 15°, 30°, 45°, 60°, 90° or any range of the above two. The first sealing ring 300 includes a first sealing segment 310 and a second sealing segment 320. The first sealing segment 310 is arranged between the first surface 1211 and the base 110 to seal the gap between the first surface 1211 and the base 110. The second sealing segment 320 is arranged between the second surface 1212 and the base 110 to seal the gap between the second surface 1212 and the base 110.

[0066] In the embodiments of the present application, by arranging the first sealing section 310 and the second sealing section 320 of the first sealing ring 300 on the two surfaces of the water pump cover plate 120 at an angle, the first sealing ring 300 is no longer arranged on the same side of the water pump cover plate 120, and the size of the water pump cover plate 120 can be reduced in at least one of the direction in which the first surface 1211 is arranged opposite to the first side wall 1111 and the direction in which the second surface 1212 is arranged opposite to the second side wall 1121, so as to reduce the size of the laundry treating apparatus, and in addition, the existing structure of the base 110 can be used for sealing, and the structure of the first side wall 1111 and the second side wall 1121 does not need to be specially designed, and the sealing method is simple and flexible.

[0067] In some embodiments, the first sealing section 310 is arranged between the first surface 1211 and the first side wall 1111 in the vertical direction G, and the second sealing section 320 is arranged between the second surface 1212 and the second side wall 1121 in the horizontal direction, so that the water pump cover plate 120 is abutted against the first side wall 1111 through the first sealing section 310 in the vertical direction G and is abutted against the second side wall 1121 through the second sealing section 320 in the horizontal direction, and the size of the water pump cover plate 120 can be reduced in the horizontal direction and the vertical direction G, and the assembly is convenient. The horizontal direction can be the front-rear direction Y of the laundry treating apparatus, or the horizontal direction can also be the left-right direction X of the laundry treating apparatus.

[0068] In some embodiments, the first sealing section 310 comprises a first fitting part 311, the first surface 1211 is provided with a second fitting part, and the first fitting part 311 is snap-fitted with the second fitting part to limit the position of the first sealing section 310 relative to the first surface 1211, and the snap-fitting mode facilitates the disassembly of the first sealing section 310. One of the first fitting parts 311 is a first clamping groove, and the other is a first clamping part, and the first clamping part is clamped in the first clamping groove, and the slot of the first clamping groove is opened towards the vertical direction G. Optionally, the first fitting part 311 is the first clamping part, and the second fitting part has the first clamping groove; or the first fitting part 311 has the first clamping groove, and the second fitting part is the first clamping part. As shown in Figure 3 The first sealing section 310 also has a first deformation part 312, the first fitting part 311 and the first deformation part 312 are integrally arranged, the first deformation part 312 protrudes relative to the first surface 1211, and the first deformation part 312 abuts against the first wall surface and can be deformed to seal the gap between the first surface 1211 and the first side wall 1111.

[0069] As shown in Figure 4As shown, the first sealing section 310 has multiple first mating parts 311 and multiple second mating parts. Each of the multiple first mating parts 311 corresponds to one of the multiple second mating parts, and the multiple first mating parts 311 are integrally formed with the first deformable part 312. When the first deformable part 312 deforms against the first wall surface, it deforms to abut against the first surface 1211. The first surface 1211 of the water pump cover plate 120 provides support for the first deformable part 312, maintaining its deformation stability.

[0070] In some embodiments, the second sealing section 320 includes a third mating portion 321, and the second surface 1212 is provided with a fourth mating portion. One of the third mating portion 321 and the fourth mating portion is a second locking groove, and the other is a second engaging portion. The second engaging portion engages with the second locking groove to define the position of the second sealing section 320 relative to the second surface 1212. The opening of the second locking groove is opened in a horizontal direction. Optionally, the third mating portion 321 is the second engaging portion, and the fourth mating portion has a second locking groove; or, the third mating portion 321 has a second locking groove, and the fourth mating portion is the second engaging portion. There is one third mating part 321 and one fourth mating part. The third mating part 321 is connected to the first deformable part 312. One part of the surface of the third mating part 321 abuts against the second surface 1212 of the water pump cover plate 120, and another part of the surface abuts against the sealing side wall surface 112a of the second side wall 1121. The third mating part 321 extends through the second sealing section 320 along the extension direction of the second sealing section 320 to form a continuous and smooth sealing structure, which helps to improve the sealing stability.

[0071] In this embodiment, the first sealing segment 310 can be installed on the pump cover 120 by engaging the first mating part 311 with the second mating part. Alternatively, the first sealing segment 310 can be integrally injection molded with the pump cover 120 to ensure proper alignment. Similarly, the second sealing segment 320 can be installed on the pump cover 120 by engaging the third mating part 321 with the fourth mating part. Alternatively, the second sealing segment 320 can be integrally injection molded with the pump cover 120 to ensure proper alignment.

[0072] In some embodiments, the first sealing section 310 and the second sealing section 320 may be made of the same material, for example, elastic silicone, elastic rubber, etc.

[0073] In some embodiments, the base 110 comprises a first side wall 1111 and a second side wall 1121, the first surface 1211 of the water pump cover plate 120 faces the first side wall 1111, the second surface 1212 of the water pump cover plate 120 faces the second side wall 1121, the first sealing section 310 is arranged between the first surface 1211 and the first side wall 1111 to seal the gap between the first surface 1211 and the first side wall 1111, and the second sealing section 320 is arranged between the second surface 1212 and the second side wall 1121 to seal the gap between the second surface 1212 and the second side wall 1121.

[0074] In some embodiments, the first side wall 1111 has a sealing end wall surface 111a, the first surface 1211 faces the sealing end wall surface 111a of the first side wall 1111, the second side wall 1121 has a sealing side wall surface 112a, the second surface 1212 faces the sealing side wall surface 112a of the second side wall 1121, the first sealing section 310 seals the gap between the first surface 1211 and the sealing end wall surface 111a of the first side wall 1111, and the second sealing section 320 seals the gap between the second surface 1212 and the sealing side wall surface 112a of the second side wall 1121, so that the first sealing section 310 and the second sealing section 320 are not arranged on the end wall surfaces of the first side wall 1111 and the second side wall 1121, nor on the side wall surfaces of the first side wall 1111 and the second side wall 1121, but one is arranged on the sealing end wall surface 111a of the first side wall 1111 and the other is arranged on the sealing side wall surface 112a of the second side wall 1121, which can not only limit the position of the water pump cover plate 120 relative to the first side wall 1111 and the second side wall 1121, but also has good sealing stability and can reduce the size of the water pump cover plate 120.

[0075] In the embodiments of the present application, the first sealing section 310 is arranged in a shape similar to the sealing end wall surface 111a of the first side wall 1111, and the second sealing section 320 is arranged in a shape similar to the sealing side wall surface 112a of the second side wall 1121.

[0076] In some embodiments, the base 110 includes a first side section 1101, a second side section 1102, a third side section 1103, and a fourth side section 1104 connected end to end. The first side section 1101 and the third side section 1103 are arranged opposite each other in a first direction, and the second side section 1102 and the fourth side section 1104 are arranged opposite each other in a second direction. The second direction is perpendicular to the first direction. Optionally, the first direction may be the front-back direction Y of the garment processing device, and the second direction may be the left-right direction X of the garment processing device. In the first direction, the distance from the first side section 1101 to the return water inlet 111b is less than the distance from the third side section 1103 to the return water inlet 111b. Optionally, at least one of the first side segment 1101, the second side segment 1102, the third side segment 1103, and the fourth side segment 1104 forms a first side wall 1111, and at least one of them forms a second side wall 1121. The number of segments of the first sealing segment 310 is equal to the number of segments of the first side wall 1111 and they are arranged in a one-to-one correspondence. The number of segments of the second sealing segment 320 is equal to the number of segments of the second side wall 1121 and they are arranged in a one-to-one correspondence.

[0077] In some embodiments, such as Figure 4 As shown, the first side section 1101, the second side section 1102, and the fourth side section 1104 together form the first side wall 1111, and the third side section 1103 forms the second side wall 1121. Correspondingly, the first sealing section 310 has three segments, and the three first sealing sections 310 correspond one-to-one with the first side section 1101, the second side section 1102, and the fourth side section 1104, respectively. The second sealing section 320 has one segment, and is set corresponding to the second side section 1102. With this shape, the first side wall 1111 can provide more stable support for the water pump cover plate 120, thereby improving the sealing stability and installation stability of the water pump cover plate 120.

[0078] In some other embodiments, the first side segment 1101 and the third side segment 1103 may be configured to jointly form the first sidewall 1111, and the second side segment 1102 and the fourth side segment 1104 may be configured to jointly form the second sidewall 1121.

[0079] like Figure 5 As shown, the garment processing equipment also includes a drain pump 500, which is mounted on the pump cover 120. At least a portion of the drain pump 500 is located in the water collection chamber 101 to pump water from the water collection chamber 101. For example, the drain pump 500 pumps water from the water collection chamber 101 to supply other structures of the garment processing equipment to achieve water recycling. Alternatively, the water collection chamber 101 is connected to an external drainage space through the drain pump 500, and the drain pump 500 pumps water from the water collection chamber 101 to discharge excess water, preventing water overflow from the water collection chamber 101 from affecting the normal use of the garment processing equipment.

[0080] In some embodiments, the water pump cover plate 120 comprises a main body portion 121 having a first surface 1211 and a second surface 1212. The water pump cover plate 120 further comprises a mounting portion 122 integrally arranged with the main body portion 121. The drain pump 500 is mounted to the mounting portion 122 and at least partially located in the water collecting cavity 101 to extract water in the water collecting cavity 101.

[0081] In some embodiments, the mounting portion 122 has a mounting opening 122a through which the drain pump 500 extends into the water collecting cavity 101. The laundry treating apparatus further comprises a second sealing ring 400 clamped between the mounting portion 122 and the drain pump 500 to seal the gap between the mounting portion 122 and the drain pump 500. Wherein, the main body portion 121 is arranged around the outer periphery of the mounting portion 122, and correspondingly, the first sealing ring 300 is arranged around the outer periphery of the mounting portion 122 to form a closed structure, the first sealing ring 300 forms a seal at the outer periphery, and the second sealing ring 400 forms a seal at the inner periphery, thereby preventing water leakage of the water collecting cavity 101.

[0082] In some embodiments, the bottom wall surface of the water collecting cavity 101 is a receiving bottom surface 112b located below the main body portion 121 in the vertical direction G, and the receiving bottom surface 112b is the lowest wall surface of the water collecting cavity 101 in the vertical direction G. In the case that the water collecting cavity 101 stores water, the receiving bottom surface 112b receives water. Optionally, the mounting portion 122 extends towards the side where the receiving bottom surface 112b is located and forms a mounting recess, and the mounting recess has a mounting opening 122a formed in the bottom wall thereof. The drain pump 500 comprises a first water inlet end 510, and the drain pump 500 is arranged in the mounting recess, and the first water inlet end 510 of the drain pump 500 extends through the mounting opening 122a to face the receiving bottom surface 112b, so that the first water inlet end 510 of the drain pump 500 extends to the lowest part of the water collecting cavity 101, and the first water inlet end 510 of the drain pump 500 can more fully extract water in the water collecting cavity 101, and the amount of water stored in the water collecting cavity 101 does not affect the operation of the drain pump 500.

[0083] In some embodiments, the distance from the first water inlet end 510 of the drain pump 500 to the receiving bottom surface 112b is H, and 1mm≤H≤20mm. In this distance range, the distance from the first water inlet end 510 of the drain pump 500 to the receiving bottom surface 112b is appropriate, so that the drain pump 500 can smoothly extract water in the water collecting cavity 101 and more fully extract water in the water collecting cavity 101. Optionally, the receiving bottom surface 112b is a plane parallel to the surface of the main body portion 121.

[0084] In some embodiments, the base 110 has a return flow channel 103 and a heat exchange channel 104, the heat exchange channel 104 being in communication with the water collecting cavity 101 through the return flow channel 103. The return flow channel 103 has a return water inlet 111b in communication with the heat exchange channel 104, water in the heat exchange channel 104 enters the return flow channel 103 through the return water inlet 111b, the wall surface of the base assembly defining the return flow channel 103 includes a return flow bottom surface 112c, water passing through the return water inlet 111b falls to the return flow bottom surface 112c and enters the water collecting cavity 101 under the guidance of the return flow bottom surface 112c. As shown in Figure 6 the return flow bottom surface 112c has a return flow edge w facing the receiving bottom surface 112b, the receiving bottom surface 112b is located below the return flow edge w in the vertical direction G, so that water in the return flow channel 103 can more fully and efficiently enter the water collecting cavity 101.

[0091] The drainage pump 500 includes a first inlet end 510, a second inlet end, and an outlet end 530. The first inlet end 510 is connected to the water collection chamber 101, the second inlet end is used to connect to an external water source, and the outlet end 530 is connected to the water flow chamber 31 of the nozzle 30. The drainage pump 500 is configured to transport the water flow from at least one of the first inlet end 510 and the second inlet end to the water flow chamber 31 through the outlet end 530, thereby recycling the water flow in the water collection chamber 101 and saving resources.

[0092] In some embodiments, the laundry treating apparatus further comprises a valve body 600 and a water storage box (not shown in the drawings), the valve body 600 being installed to the air duct cover plate 140. The valve body 600 comprises a first interface, a second interface and a third interface, the first interface being in communication with the water outlet end 530 of the drain pump 500, the second interface being in communication with the water flow cavity 31, and the third interface being in communication with an external drain space or the water storage box.

[0093] In some embodiments, the inner tub 10 is arranged at a side of the nozzle 30 away from the air duct cover plate 140, the valve body 600 is installed to a side of the air duct cover plate 140 facing the inner tub 10, and the valve body 600 is arranged at a side of the center axis of the inner tub 10 in the horizontal direction, so that the space is fully utilized, the structure inside the laundry treating apparatus is compact, and the valve body 600 and the pipeline connected to the valve body 600 are also convenient to install and maintain.

[0094] It can be understood that when the water discharged from other channels of the laundry treating apparatus enters the water collecting cavity 101, the water flow entering will impact the water in the water collecting cavity 101, causing the water in the water collecting cavity 101 to fluctuate, and when the water pump 500 pumps the water in the water collecting cavity 101, the vibration generated by the water pump 500 will also cause the water in the water collecting cavity 101 to fluctuate, and in addition, the vibration generated when other structures of the laundry treating apparatus work will also cause the water in the water collecting cavity 101 to fluctuate. In these cases, the fluctuating water surface in the water collecting cavity 101 will interfere with the determination of the water level in the water collecting cavity 101, for example, when a single water level sensing module 200 is used, the single water level sensing module 200 can only sense the water level in a local area, and the water level sensed by the single water level sensing module 200 does not represent the water level in the entire water collecting cavity 101, so when the single water level sensing module 200 does not detect that the water level in its corresponding area exceeds the preset water level, the water level in other areas of the water collecting cavity 101 can have already exceeded the preset water level, and there is a risk of water overflow.

[0095] In combination with Figure 7 and Figure 8 , the laundry treating apparatus further comprises a plurality of water level sensing modules 200, which are installed on the base assembly, wherein the plurality of water level sensing modules 200 are distributed at intervals, and each water level sensing module 200 is used to sense the water level in a corresponding area of the water collecting cavity 101, so as to determine the water level state in the water collecting cavity 101 according to the obtained water level in at least one area of the water collecting cavity 101.

[0096] In the embodiments of the present application, by providing a plurality of water level sensing modules 200 to monitor the water levels in a plurality of areas of the water collecting cavity 101, the plurality of water level sensing modules 200 can cover more areas for monitoring, reducing the existence of monitoring dead angles. The water level in any one of the plurality of areas corresponding to the plurality of water level sensing modules 200 can be monitored, and when the water level in any one of the areas is higher than the preset water level, it can be used to determine that there is a risk of water overflow in the water collecting cavity 101, so as to timely drain the water in the water collecting cavity 101 to prevent the situation that the monitoring area 102 is too small to fully monitor the water level in the water collecting cavity 101 when a single water level sensing module 200 is used, or the water level is misjudged due to the water surface fluctuation interfering with the determination of the water level by the water level sensing module 200.

[0097] As shown in Figure 8 , the part of the base assembly surrounding the outer periphery of the water pump 500 is divided into a plurality of monitoring areas 102, and the plurality of monitoring areas 102 are provided one by one corresponding to the plurality of areas of the water collecting cavity 101. At least two monitoring areas 102 are provided with water level sensing modules 200, and the more the number of water level sensing modules 200, the more areas they can cover, and the water level in the water collecting cavity 101 is more comprehensively monitored. Optionally, in combination with Figure 8 andFigure 9 The drainage pump 500 has a first water inlet end 510 for pumping water, and a plurality of monitoring areas 102 are divided around the first water inlet end 510 at equal central angles. Figure 7 In the embodiment, the boundary line M and the boundary line N intersect and are perpendicular, i.e., four monitoring areas 102 are divided.

[0098] Optionally, when some of the monitoring areas 102 are provided with the water level sensing module 200, and the same number of monitoring areas 102 are provided with the water level sensing module 200, the line formed by sequentially connecting the centers of the selected monitoring areas 102 provided with the water level sensing module 200 is the longest. For example, the part of the base assembly surrounding the outer periphery of the drainage pump 500 is divided into four monitoring areas 102, which are the first monitoring area 1021, the second monitoring area 1022, the third monitoring area 1023, and the fourth monitoring area 1024. In the left-right direction X of the laundry treating apparatus, the first monitoring area 1021 and the second monitoring area 1022 are arranged on opposite sides of the drainage pump 500, and in the front-rear direction Y of the laundry treating apparatus, the third monitoring area 1023 and the fourth monitoring area 1024 are arranged on opposite sides of the drainage pump 500 (the third monitoring area 1023 is on the front side of the drainage pump 500, and the fourth monitoring area 1024 is on the rear side of the drainage pump 500). When the laundry treating apparatus has two water level sensing modules 200, two of the four monitoring areas 102 are selected to be provided with the water level sensing module 200, and the two monitoring areas 102 selected are oppositely arranged, i.e., the first monitoring area 1021 and the second monitoring area 1022 are selected to be provided with the water level sensing module 200, or the third monitoring area 1023 and the fourth monitoring area 1024 are selected to be provided with the water level sensing module 200. When the laundry treating apparatus has three water level sensing modules 200, three of the four monitoring areas 102 are selected to be provided with the water level sensing module 200, and any three of the four monitoring areas 102 are selected to be provided with the water level sensing module 200.

[0099] It can be understood that when the clothes processing equipment needs to be installed into a use scene, the space available to the clothes processing equipment in the front-rear direction Y is relatively cramped due to the installation space, and in the case where the base assembly has the four monitoring areas 102 of the first monitoring area 1021, the second monitoring area 1022, the third monitoring area 1023, and the fourth monitoring area 1024, when the number of water level sensing modules 200 is two, the first monitoring area 1021 and the second monitoring area 1022 that are relatively arranged in the left-right direction X of the clothes processing equipment can be selected to be respectively provided with the water level sensing modules 200, when the number of water level sensing modules 200 is three, the first monitoring area 1021 and the second monitoring area 1022 that are relatively arranged in the left-right direction X of the clothes processing equipment can be selected to be respectively provided with the water level sensing modules 200, and the four monitoring areas 102 are selected to be provided with one more water level sensing module 200.

[0100] In other embodiments, the part of the base assembly surrounding the outer periphery of the drain pump 500 can be divided into a larger number of monitoring areas 102, for example, the number of monitoring areas 102 is 5, 6, etc., and correspondingly, 3, 4 of them can be selected to be provided with the water level sensing modules 200.

[0101] The clothes processing equipment has an inner tub 10, which has a clothes processing cavity for accommodating wet clothes. The wet and cold gas after processing the wet clothes in the clothes processing cavity enters the heat exchange channel 104, and the heat exchange assembly is arranged in the heat exchange channel 104. The heat exchange assembly is used to remove water in the wet and cold gas and convert the wet and cold gas into dry and hot gas, and the dry and hot gas flows back to the clothes processing cavity to perform drying treatment on the wet clothes in the clothes processing cavity. The backflow flow channel 103 is connected to the heat exchange channel 104 and the water collecting cavity 101, respectively. The water in the heat exchange channel 104 can be transported to the water collecting cavity 101 for storage through the backflow flow channel 103. When the water collecting cavity 101 is full, there may be excess water overflowing from the backflow flow channel 103 into the heat exchange channel 104, increasing the humidity in the heat exchange channel 104, and there may also be splashing onto the heat exchange assembly to interfere with the operation of the heat exchange assembly. By arranging multiple water level sensing modules 200, the water level in the water collecting cavity 101 can be more comprehensively monitored to prevent overflow from the water collecting cavity 101 into the heat exchange channel 104.

[0102] In some embodiments, in the front-rear direction Y of the laundry treating apparatus, the heat exchange channel 104 is located at the rear side of the water collecting cavity 101, and in the vertical direction G, the backflow flow channel 103 is located below the heat exchange channel 104 to receive the water flowing out of the heat exchange channel 104 and deliver the water to the water collecting cavity 101, forming a smooth water flow transmission path. In this way, in the left-right direction X of the laundry treating apparatus, more space can be reserved for the backflow flow channel 103, so that the backflow flow channel 103 can also be used to store a certain amount of water, and it is also convenient to design the shape of the backflow flow channel 103 so that the water in the backflow flow channel 103 can enter the water collecting cavity 101 at a suitable angle, reducing the interference of the water in the backflow flow channel 103 with the water in the water collecting cavity 101 during the process of entering the water collecting cavity 101. At the same time, it is also convenient to expand the size of the water collecting cavity 101 in the left-right direction X of the laundry treating apparatus, and to reduce the space occupied by the water collecting cavity 101 in the front-rear direction Y of the laundry treating apparatus while meeting the space requirement of the drain pump 500.

[0103] In some embodiments, the water level sensing module 200 and the drain pump 500 are both mounted on the water pump cover plate 120, and the drain pump 500 and the water level sensing module 200 are mounted on the same water pump cover plate 120, which is convenient for assembly and also convenient for designing the positions of multiple water level sensing modules 200 relative to the drain pump 500 so that the multiple water level sensing modules 200 are in more suitable positions to monitor the water level of the corresponding regions of the water collecting cavity 101.

[0104] The water pump cover plate 120 also has multiple water level openings 121a that communicate with the water collecting cavity 101, and the multiple water level sensing modules 200 are installed on the water pump cover plate 120 one-to-one corresponding to the multiple water level openings 121a.

[0105] In some embodiments, in combination with Figure 9 and Figure 10 The main body 121 has multiple water level openings 121a, and the multiple water level sensing modules 200 are installed on the main body 121 one-to-one corresponding to the multiple water level openings 121a. Optionally, the main body 121 is in the form of a flat plate parallel to the horizontal direction, and the multiple water level sensing modules 200 are installed on the main body 121, so that the multiple water level sensing modules 200 can be installed on the same horizontal plane, so that the multiple water level sensing modules 200 are at the same height to detect the water level of the corresponding regions in the water collecting cavity 101, and in the case that the water collecting cavity 101 is filled with water, the water level of the region of the water collecting cavity 101 corresponding to the main body 121 is also uniform.

[0106] In the embodiments of the present application, in addition to being installed on the water pump cover plate 120, the water level sensing module 200 can also be installed on the base 110 in some other embodiments, for example, the water level sensing module 200 is installed on the first side wall 1111 or the first side wall 1121.

[0107] In the embodiments of the present application, the type of the water level sensing module 200 is not particularly limited, and any water level sensing module 200 capable of detecting water level in the art is applicable to the present application. For example, the water level sensing module 200 can be a float sensing module, a radar liquid level sensing module, or an ultrasonic liquid level sensing module, etc.

[0108] In some embodiments, the water level sensing module 200 is a float sensing module, which includes a float sensor 210 and a float 220. The float sensor 210 is installed on the base assembly through the water level opening 121a, and the float 220 is movably installed on the float sensor 210 along the vertical direction G. The float 220 floats on the water surface in the water collecting cavity 101 and floats up and down with the water surface to trigger the float sensor 210 to generate a water level signal, so as to obtain the water level of the corresponding area in the water collecting cavity 101 according to the water level signal. In other embodiments, the water level sensing module 200 can also be a radar liquid level sensing module, an ultrasonic liquid level sensing module, etc.

[0109] In some embodiments, the float sensor 210 is configured to generate a full water signal when the float 220 floats to a preset position and continuously stays for a preset time. The drain pump 500 drains the water in the water collecting cavity 101 to the outside of the water collecting cavity 101 according to the full water signal. Optionally, the float sensing module further includes a snap spring 230 installed on the float 220 and movably along with the float 220. When the float 220 floats up to the snap spring 230 acting on the float sensor 210, it indicates that the float 220 floats to the preset position, and after continuously staying for a preset time, the float sensor 210 is triggered to generate a full water signal. The preset time range can be 5s-15s.
