Multiple types of laundry detergents may include, but are not limited to, the following categories: detergent, fabric softener, disinfectant, fragrance, bleach, and baby-specific laundry products.

[0003] Most existing multi-drum washing machines use a venturi suction system for their automatic detergent dispensing system. This system relies on negative pressure to selectively extract various detergents from the storage chamber into the water supply line, and then uses a switching valve to connect them to the corresponding water tanks. Over time, detergent deposits and scale build up in the detergent storage tanks of traditional washing machines, requiring users to manually add water for cleaning, thus reducing the user experience.

[0042] like Figures 1-6 As shown, to solve the problem of inconvenient cleaning of detergent deposits and scale buildup in the liquid storage tank of existing washing machines, the dispensing device 1 for washing equipment of the present invention is provided with a self-cleaning water path, which is formed on the inner and outer surfaces of the dispensing device 1 by hot-melt welding. Specifically, the dispensing device 1 includes a body 18 and a first water path plate 19, which is disposed on the second surface 21 of the body 18.

The dispensing device 1 also includes a water inlet 12 and a water path switcher 13, which are connected sequentially through the first sub-water path 24, the second sub-water path 25, and the third sub-water path 26. A water inlet valve 50 is provided at the water inlet 12.

[0043] The dispensing device 1 also has a second water inlet channel 14 on its surface. The main body 18 of the dispensing device 1 contains a first liquid storage tank 27 and at least one second liquid storage tank 28. The second water inlet channel 14 includes a fourth sub-channel 29 and at least one fifth sub-channel 30 disposed on the first surface 20 of the main body 18, and a sixth sub-channel 31 and at least one seventh sub-channel 32 disposed on the first water channel plate 19. The dispensing device 1 also includes a liquid filling channel 34 and a second water channel plate 33, which are disposed on the fourth surface 23 of the main body 18. The liquid filling channel 34 includes a first sub-channel 35 and at least one second sub-channel 36. The first sub-channel 35 communicates with the first liquid storage tank 27, and the second sub-channel 36 communicates with the second liquid storage tank 28. The second water inlet channel 14 also includes an eighth sub-water channel 37 and at least a ninth sub-water channel 40 disposed on the fourth surface 23 of the main body 18, and a tenth sub-water channel 41 and at least an eleventh sub-water channel 42 disposed on the second water channel plate 33. The tenth sub-water channel 41 and the eleventh sub-water channel 42 are respectively connected to the first sub-channel 35 and the second sub-channel 36. The water channel switch 13 and the first liquid storage tank 27 are connected sequentially through the fourth sub-water channel 29, the sixth sub-water channel 31, the eighth sub-water channel 37, the tenth sub-water channel 41 and the first sub-channel 35. The water channel switch 13 and the second liquid storage tank 28 are connected sequentially through the fifth sub-water channel 30, the seventh sub-water channel 32, the ninth sub-water channel 40, the eleventh sub-water channel 42 and the second sub-channel 36.

[0044] The self-cleaning water path also includes a drainage water path disposed on the surface of the dispensing device 1. The dispensing device 1 also includes a dispensing pump 17. The main body 18 is provided with a first liquid storage tank 27 and at least one second liquid storage tank 28. The bottom of the first liquid storage tank 27 and the second liquid storage tank 28 are respectively provided with a first liquid outlet 43 and a second liquid outlet 44. Drain valves (not shown in the figure) are provided at the first liquid outlet 43 and the second liquid outlet 44. The drainage water path includes a twelfth sub-water path 45 and at least one thirteenth sub-water path 46 disposed on the fourth surface 23 of the main body 18. The first liquid storage tank 27 and the dispensing pump 17 are connected through the first liquid outlet 43 and the twelfth sub-water path 45. The second liquid storage tank 28 and the dispensing pump 17 are connected through the second liquid outlet 44 and the thirteenth sub-water path 46.

[0045] The operation of the dispensing device 1 of the present invention will be described under the above-described embodiments. When the washing machine is running in self-cleaning mode, the controller controls the water inlet valve 50 to open. Water enters the water circuit switcher 13 after passing through the first sub-water circuit 24, the second sub-water circuit 25 and the third sub-water circuit 26 from the water inlet 12. At this time, the water circuit switcher 13 connects the fourth sub-water circuit 29 and the fifth sub-water circuit 30. Water enters the sixth sub-water circuit 31 and the seventh sub-water circuit 32, the eighth sub-water circuit 37 and the ninth sub-water circuit 40, the tenth sub-water circuit 41 and the eleventh sub-water circuit 42 in sequence along the fourth sub-water circuit 29 and the fifth sub-water circuit 30. Finally, water enters the first sub-channel 35 and the second sub-channel 36 of the liquid filling channel 34 through the holes on the tenth sub-water circuit 41 and the first liquid storage tank 27 and the second liquid storage tank 28 respectively. After rinsing the first liquid storage tank 27 and the second liquid storage tank 28, the drain valve is opened, and the washing water in the first liquid storage tank 27 and the second liquid storage tank 28 is discharged through the negative pressure of the dosing pump 17 along the twelfth sub-water passage 45 and the thirteenth sub-water passage 46, respectively, thereby completing the cleaning of the first liquid storage tank 27 and the second liquid storage tank 28.

[0046] The advantages of the above-described embodiments are as follows: The dispensing device 1 for washing equipment of the present invention provides a self-cleaning water path by means of hot-melt welding on the inner and outer surfaces of the dispensing device 1. This self-cleaning water path automatically flushes away dirt in the liquid storage tank, solving the problem of inconvenient cleaning of detergent deposits and scale buildup in the liquid storage tank of existing washing machines. Furthermore, since the self-cleaning water path of the present invention is formed on the surface of the dispensing device 1 by hot-melt welding, it does not significantly increase the volume of the dispensing device 1, avoiding a complex internal water path. In addition, since the water also passes through the liquid filling channel 34 in this embodiment, it can also flush away residual detergent in the liquid filling channel 34, further improving the self-cleaning effect of the dispensing device 1. Furthermore, regarding the aforementioned self-cleaning water path, those skilled in the art can choose to place it on the outer or inner surface of the dispensing device 1 according to actual conditions. Additionally, regarding the setting method of the self-cleaning water path, those skilled in the art can also choose other common setting methods, such as snap-fit, and these modifications are all within the protection scope of the present invention.

[0047] In one possible implementation, instead of providing a liquid filling channel 34 on the fourth surface 23 of the body 18, a liquid filling port is directly provided on the fourth surface 23 of the body 18. Correspondingly, the second water inlet channel 14 includes a fourth sub-water channel 29 and at least one fifth sub-water channel 30 provided on the first surface 20 of the body 18, and a sixth sub-water channel 31 and at least one seventh sub-water channel 32 provided on the first water channel plate 19. The water channel switch 13 and the first liquid storage tank 27 are connected sequentially through the fourth sub-water channel 29 and the sixth sub-water channel 31, and the water channel switch 13 and the second liquid storage tank 28 are connected sequentially through the fifth sub-water channel 30 and the seventh sub-water channel 32.

[0048] The advantages of the above-described embodiment are as follows: Compared with the aforementioned embodiments, since the liquid filling channel 34 is not provided on the fourth surface 23 of the main body 18 in this embodiment, but a liquid filling port is directly provided, the volume of the dispensing device 1 is reduced, thereby reducing the space occupied inside the washing machine. On the other hand, not providing a liquid filling channel 34 can also avoid detergent residue in the liquid filling channel 34, thus eliminating the cleaning process of the liquid filling channel 34. Furthermore, in this embodiment, water can be directly injected into the first liquid storage tank 27 and the second liquid storage tank 28 for cleaning through the sixth sub-water channel 31 and the seventh sub-water channel 32 on the first water channel plate 19, which also simplifies the structure of the second water inlet channel 14.

[0049] Furthermore, such as Figure 4 As shown, in one possible implementation, a first water level detection element 47, a second water level detection element 48, and a third water level detection element 49 are provided inside the liquid storage tank. The first water level detection element 47 is located at the bottom of the liquid storage tank, the third water level detection element 49 is located at the top of the liquid storage tank, and the second water level detection element 48 is located near the bottom of the liquid storage tank.

[0050] With the above-described implementation, whether adding detergent or water to the storage tank or draining detergent or water, the liquid level in the storage tank can be detected by the water level detector, and the adding and draining processes can be automatically controlled based on the liquid level, improving the user experience. Furthermore, this embodiment also includes a second water level detector 48 located near the bottom of the storage tank. This second water level detector 48 serves as a detection device for a liquid level warning signal in the storage tank. When the detergent level in the storage tank is lower than the position of the second water level detector 48, an indicator light or other prompt can be sent to the user, reminding them to add detergent to the storage tank in time to avoid affecting the washing process of the clothes.

[0051] In addition, the present invention also provides a washing device, including the dispensing device 1 for washing device described in the above embodiments.

[0052] Furthermore, the present invention also provides a control method for a washing device, the washing device including the dispensing device 1 for the washing device described in the above embodiments, a water level detection device being installed in the liquid storage tank of the washing device, a water inlet valve 50 being installed at the water inlet 12, and a drain valve being installed on the drain pipe, wherein the dispensing pump 17, the water circuit switch 13, the water level detection device, the water inlet valve 50, and the drain valve are all communicatively connected to the controller of the washing device, such as... Figure 7 As shown, the control methods include:

[0053] S1. Obtain self-cleaning instructions;

[0054] S2, control the water circuit switcher 13 to switch water circuits;

[0055] S3. Control the inlet valve 50 to open and control the dispensing pump 17 to start;

[0056] S4. Control the water level detection device to obtain the water level in the storage tank;

[0057] S5. Compare the water level in the storage tank with the preset water level;

[0058] S6. If the water level in the storage tank is greater than or equal to the preset water level, the drain valve will be opened.

[0059] When the washing equipment of the present invention operates in self-cleaning mode, a self-cleaning command is first obtained, and then the water circuit switcher 13 is controlled to switch the water circuit to the self-cleaning water circuit. Subsequently, the inlet valve 50 is opened, and the dispensing pump 17 is started, allowing water to enter the storage tank along the first inlet water circuit 11 and the second inlet water circuit 14. At the same time, the water level detection device is controlled to obtain the water level in the storage tank and compare it with the preset water level. If the water level in the storage tank is greater than or equal to the preset water level, it indicates that the water intake has reached the standard. At this time, the drain valve is opened to discharge the washing water after rinsing the storage tank, thereby completing the automatic cleaning of the storage tank.

[0060] It should be noted that the above embodiments are merely used to illustrate the principles of the present invention and are not intended to limit the scope of protection of the present invention. Without departing from the principles of the present invention, those skilled in the art can adjust the above structure so that the present invention can be applied to more specific application scenarios.

[0061] The technical solution of the present invention has been described above with reference to the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the scope of protection of the present invention is obviously not limited to these specific embodiments. Without departing from the principles of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after such changes or substitutions will all fall within the scope of protection of the present invention.
