[0002] Currently, many washing machines on the market have added the function of automatically adding detergent, that is, a large amount of detergent can be stored in the washing machine. When washing clothes, the weight of the user's clothes is first detected, and then an appropriate amount of detergent is added.

[0003] For washing machines with the above functions, detergent residue is inevitable in the detergent storage device. If the user wants to change to a different brand of detergent, the two brands of detergent may deteriorate due to different chemical compositions, reduce the cleaning effect, or even clump and cannot be extracted. Therefore, it is generally recommended that the user clean the detergent storage device before changing to a different detergent. If the user does not use the washing machine for a long time, the detergent dries up and hardens in the storage device, and the user also needs to clean the device.

[0004] In view of the above situation, if the user only fills the detergent storage device with water for cleaning, the residual detergent will dissolve slowly, the cleaning position will not be comprehensive when the water is still, and the piston pump and internal delivery pipe for extracting the detergent will also be difficult to clean.

[0026] In a preferred embodiment, the transmission device 3 includes a piston pump 31 and an internal delivery pipe 32. The piston pump 31 is fixed to one side of the storage box 1 and is connected to the storage box 1 through the extraction pipe 33. The internal transmission pipe is located in the storage box 1. One end of the internal transmission pipe is connected to the piston pump 31, and the other end passes through the side wall of the storage box 1 and extends to the outside of the storage box 1. The hot water inside the storage box 1 can be transmitted to the inside of the internal delivery pipe 32 through the piston pump 31, so that the piston pump 31 and the internal delivery pipe 32 can be cleaned in all directions.

[0027] In a preferred embodiment, the water injection device 4 includes a water injection pipe 41 and a water inlet valve 42 . The water injection pipe 41 is connected to the storage box 1 . The water inlet valve 42 is fixed on the water injection pipe 41 and is used to control the opening of the water flow inside the water injection pipe 41 .

[0028] In a preferred embodiment, the suction device 5 includes an air suction pipe 51 and a vacuum pump 52 . The air suction pipe 51 is connected to the storage box 1 . The vacuum pump 52 is fixed on the air suction pipe 51 and is used to extract the air inside the storage box 1 .

[0029] In a preferred embodiment, a liquid level sensor 6 for detecting the water level is fixed on the air suction pipe 51, which can detect the real-time water level inside the storage box 1 to prevent the water level from being too high or too low and affecting the cleaning effect.

[0030] In a preferred embodiment, a temperature sensor 7 for detecting the water temperature inside the storage box 1 is also fixed on the storage box 1, which can detect the real-time temperature of the water inside the storage box 1 to prevent the water level from being too high or too low and affecting the cleaning process.

[0031] like Figure 1 As shown, in a preferred embodiment, the lower end of the storage box 1 is also connected to a drainage device 8 for draining water from the storage box 1. Furthermore, the drainage device 8 includes a drainage pipe 81 and a drainage valve 82. The drainage valve 82 is connected to the lower end of the storage box 1. The drainage valve 82 is fixed on the drainage pipe 81 and is used to control the opening of the water flow inside the drainage pipe 81.

[0033] In this embodiment, a method of using a detergent box cleaning system is as follows:

[0034] Automatically extract detergent to surprise clothes when washing: the storage box 1 is mainly used for storing detergent, and the user can pour a large amount of detergent into the top opening covered by the sealing cover 9. The piston pump 31 for extracting detergent is installed at the lower side of the side wall of the storage box 1. The bottom of the storage box 1 is an inclined surface. The extraction port of the piston pump 31 is at the lowest point of the inclined surface. The detergent can flow along the inclined surface into the extraction pipe 33 of the piston pump 31 to reduce the residual detergent; the piston pump 31 draws the detergent into the piston pump 31, then inputs it into the internal delivery pipe 32, and then flows out from the internal delivery pipe 32. When washing clothes, according to the amount of clothes that the user needs to wash, extract the appropriate amount of detergent to wash the clothes.

[0035] When the detergent box needs to be cleaned: the user first covers the sealing cover 9 and starts the detergent box cleaning function of the washing machine. The water inlet valve 42 is opened to fill water into the storage box 1, and the liquid level sensor 6 detects the water level. When the water level reaches the set cleaning water level, the water inlet valve 42 is closed to stop the water inlet; the heating device 2 is started to heat the water in the storage box 1, and the temperature sensor 7 detects the water temperature therein. When the water temperature reaches the set cleaning temperature (the specific water temperature is selected between 60°C and 80°C, depending on the actual cleaning effect), the heating device 2 stops heating; the vacuum pump 52 is started to extract the air therein, and when the air pressure in the storage box 1 is reduced, the hot water in the storage box 1 can automatically boil to clean the storage box 1; the piston pump 31 is started during the cleaning process, and hot water is extracted to clean the piston pump 31 and the internal delivery pipe 32; when the set cleaning program is completed, the drain valve 82 is started, and the vacuum pump 52 is depressurized and ventilated at the same time, so that the water is discharged from the bottom drain pipe 81. According to the cleaning effect of one time, it can be set to repeat the above steps for multiple times to make the detergent box clean more thoroughly.

[0036] This embodiment also provides a washing machine, including the above-mentioned detergent box cleaning system.
