[0063] The structure can be part of a dehumidifier. Specifically, the water pump structure includes a housing 1, a water tank 2, a drain pump 3, a filter connector 4, a water pump connector 5, a first drain pipe 6, a second drain pipe, and a water pump connector 7.

[0064] The water tank 2 is movably connected to the inside of the casing 1, allowing the user to easily push the water tank 2 to the outside of the casing 1 for cleaning. The drain pump 3 can be a diaphragm pump, which can be installed on the top of the casing 1. The filter connector 4 is detachably installed inside the water tank 2. The water pump connector 5 is located on the casing 1 and communicates with the drain outlet 201 of the water tank 2. For example, the water pump connector 5 can be installed on the side of the casing 1.

[0065] The first drain pipe 6 is connected to the filter connector 4 and the drain outlet 201 of the water tank 2 at both ends, respectively; the second drain pipe is connected to the water pump connector 5 and the input end of the drain pump 3 at both ends, respectively; the pump connector 7 is located on the housing 1, and the pump connector 7 can be connected to the output end of the drain pump 3 through the third drain pipe 12.

[0066] When the drain pump 3 is working, the water in the water tank 2 enters the first drain pipe 6 through the filter connector 4, and then sequentially enters the pump connector 7 through the second drain pipe, the drain pump 3, and the third drain pipe 12. The pump connector 7 can be connected to an external drain pipe (not shown in the attached diagram), which can lead to facilities such as a water tank or drainage ditch. This allows the water in the water tank 2 to be pumped out of the machine by the drain pump 3, eliminating the need for the user to move the water tank 2 to empty it, thus improving the user experience of dehumidifiers and other household appliances. Because the water tank 2 is equipped with the filter connector 4, when the water in the water tank 2 enters the drain pump 3 through the first drain pipe 6 and the second drain pipe, the filter connector 4 can filter out impurities in the water, preventing impurities from being introduced into the drain pump 3. This extends the service life of the drain pump 3 without increasing the operating and maintenance costs of the household appliance.

[0067] like Figure 4 and Figure 5 As shown, optionally, the filter connector 4 includes a connector portion 41 and a filter screen 42. The connector portion 41 is used to connect to the first drain pipe 6, and the connector portion 41 can be snapped into the bottom of the water tank 2. Therefore, when the water tank 2 contains condensate, the connector portion 41 will not float in the water tank 2 due to the impact of the water, thus ensuring that the pump operation can proceed normally. The filter screen 42 can be installed on the connector portion 41 by interference fit, thereby ensuring that the filter screen 42 and the connector portion 41 are firmly connected, and the filter screen 42 is easy to disassemble and replace.

[0068] like Figure 4 and Figure 5 As shown, optionally, the connector 41 includes a pipe fitting 411 and buckle plates 412 on both sides of the pipe fitting 411. The pipe fitting 411 may be provided with a connector 41 portion for connection to the first drain pipe 6. A support plate 8 and a buckle 9 are vertically provided at the inner bottom of the water tank 2; the buckle plate 412 rests on the support plate 8 so that the filter screen 42 on the filter connector 4 does not contact the inner bottom of the water tank 2. Furthermore, the buckle plate 412 has a slot 4121 for the buckle 9 to engage. The buckle 9 can be an injection-molded elastic buckle 9. When it is necessary to remove the filter connector 4 from the water tank 2, the buckle 9 can be disengaged from the slot 4121 by moving it, thus making the disassembly and replacement of the filter connector 4 very convenient.

[0069] like Figure 6 and Figure 7As shown, optionally, the water pump connector 5 includes a first connector 51 and a first sealing ring 52. The first connector 51 has a first insertion end 511 that inserts into the drain port 201 of the water tank 2, and the first connector 51 can be injection molded from ABS material; the first sealing ring 52 is sleeved on the first insertion end 511, and it can be molded from POM (polyoxymethylene) material with good toughness, wear resistance and specific elastic deformation capability. This allows the first sealing ring 52 to be sleeved on the first connector 51 through an interference fit, while also reducing the wear of the first sealing ring 52, so that the first sealing ring 52 can seal the drain port 201 of the water tank 2 for a long time, thereby reducing the occurrence of water leakage.

[0070] like Figure 6 As shown, optionally, a sealing ring 521 is provided on the first sealing ring 52 along the circumference of the first sealing ring 52, and at least three sealing rings 521 are provided. The arrangement of multiple sealing rings 521 can increase the sealing performance of the first sealing ring 52, thereby further reducing the occurrence of water leakage.

[0071] like Figure 7 , Figure 12 as well as Figure 13 As shown, optionally, a limiting nozzle 202 is provided at the drain outlet 201 of the water tank 2, and the limiting nozzle 202 may be duckbill shaped. The water pump connector 5 is inserted into the limiting nozzle 202, and the first sealing ring 52 is in close contact with the inner wall of the drain outlet 101, thereby achieving an excellent waterproof sealing effect. In this embodiment, the water pump connector 5 can be fixed to the side of the housing 1 by the mounting component. When the user installs the water tank 2, the water pump connector 5 can be used for positioning. When the water pump connector 5 is located inside the limiting nozzle 202, and the water tank 2 cannot be pushed further in the direction of the water pump connector 5, the water tank 2 is just installed in place, thereby ensuring that the first sealing ring 52 can effectively waterproof and seal the drain outlet 201 of the water tank 2, so that there will be no leakage when the water in the water tank 2 is discharged from the water tank 2.

[0072] In addition, the limiting nozzle 202 also serves to install the first drain pipe 6.

[0073] like Figure 1 , Figure 3 As shown, optionally, the top of the housing 1 is provided with a drain cover 10, and the drain cover 10 is provided with a drain nozzle 101; the pump water connector 7 is inserted into one end of the drain nozzle 101, and the other end of the drain nozzle 101 can be connected to the aforementioned external drain pipe, thereby allowing the water in the water tank 2 to be discharged to the outside of the machine through the drain nozzle 101 and the external drain pipe.

[0074] like Figure 1 , Figures 8 to 12As shown, optionally, the water pump connector 7 includes a second connector 71, a second sealing ring 72, and a third sealing ring 73. The second connector 71 has a second insertion end 711 for inserting into the drain nozzle 101. The second sealing ring 72 and the third sealing ring 73 are both fitted onto the second insertion end 711, forming a multi-stage sealing structure for the drain nozzle 101, thereby reducing the occurrence of water leakage at the connection between the water pump connector 7 and the drain nozzle 101.

[0075] like Figure 14 and Figure 15 As shown, optionally, the water tank 2 is slidably connected to the inner side of the housing 1. The two sides of the water tank 2 are provided with grip grooves 203 to facilitate pushing the water tank 2. The inner bottom of the housing 1 is provided with guide ribs 11 that cooperate with the bottom of the water tank 2, which can help the user install the water tank 2 into the correct position inside the housing 1.

[0076] This utility model also provides a household appliance, including the aforementioned water pumping structure. The household appliance may include dehumidifiers, air conditioners, etc., thereby enabling the water pumping structure provided by this utility model to be applied to a variety of commonly used household appliances, improving users' quality of life while reducing the burden of product use.

[0077] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
