[0029] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments described are not intended to limit the present invention.
[0030] Reference Figures 1-3 As shown, this invention discloses a water circulation cleaning system for use in a washer-dryer combo, comprising: a drum body 1, a drying unit 2, and a circulation unit 3. The drum body 1 has a water inlet 11, a drain 12, and a bubble hole 13. The water inlet 11 is connected to an external water supply pipe, allowing water from the external water supply pipe to be introduced into the drum body 1 for washing clothes. The drying unit 2 dries the clothes in the drum body 1. During drying, condensate is generated using the principle of heat exchange. The drying unit 2 includes a water inlet circuit 21 and a water outlet circuit 22, with the water outlet circuit 22 discharging the condensate. The circulation unit 3 includes a drain pump 31, a feeding module 32, and a water pump 33. The inlet of the drain pump 31 is connected to the drain hole 12 and the outlet circuit 22. Water in the cylinder 1 and the drying unit 2 can be discharged into the drain pump 31. The outlet of the drain pump 31 is connected to the feeding module 32 and the external drainage pipe 5 respectively. By controlling the switch of the drain pump 31, water in the drain pump 31 can be introduced into the feeding module 32 and the external drainage pipe 5 respectively, so as to realize the circulation and discharge of water in the cylinder 1. The inlet of the water pump 33 is connected to the feeding module 32. The outlet of the water pump 33 is connected to the inlet circuit 21 and the bubble hole 13. The water introduced into the feeding module 32 is pumped into the cylinder 1 and the drying unit 2 respectively by the water pump 33, so as to realize the cleaning of the cylinder 1 and the drying unit 2.
[0031] The water circulation cleaning system of the present invention is equipped with a drain pump 31 and a water pump 33 in the circulation unit 3, which can realize the circulation flow of water between the cylinder 1 and the drying unit 2. It can not only clean the cylinder 1 and the circulation loop, but also thoroughly clean the drying unit 2. Furthermore, the water injected into the cylinder 1 can also be introduced into the drying unit 2, which can realize independent or simultaneous cleaning of the cylinder 1 and the drying unit 2, and further save water resources.
[0032] It should be noted that the circulation unit 3 is also equipped with a feeding module 32. When cleaning, bactericidal liquid and cleaning liquid can be added to the feeding module 32. The water pump 33 introduces the bactericidal liquid and cleaning liquid into the cylinder 1 and the drying unit 2 to achieve deep cleaning of the cylinder 1 and the drying unit 2.
[0033] Specifically, when cleaning the drying unit 2, the water inlet circuit 21 can be introduced into the heat exchange condensate chamber, water storage tank and filter screen in the drying unit 2 respectively for cleaning.
[0034] Reference Figure 1 and Figure 4 As shown, in this embodiment, in order to clean the cylinder 1, the water pump 33 is connected to the bubble hole 13, and water is introduced into the bubble hole 13 and then discharged into the cylinder 1. In order to generate foam in the bubble hole 13, a foam generator 4 is also provided between the cylinder 1 and the water pump 33. Furthermore, an air return hole 14 is also provided on the cylinder 1. The foam generator 4 includes a water inlet 41, an air inlet 42, and a bubble hole 43. The water inlet 41 is connected to the bubble hole 13. The water pump 33 is connected, and water enters the foam generator 4 from the inlet 41 under the pumping action of the water pump 33. The air inlet 42 is connected to the air return hole 14, and air is sent to the foam generator 4 through the air return hole 14. Under the action of the airflow, the water flow can be dispersed, thereby generating bubbles. The bubble outlet 43 is connected to the bubble hole 13. The bubbles generated at the bubble outlet 43 enter the cylinder 1 through the bubble hole 13, thereby cleaning the cylinder 1.
[0035] Specifically, in this embodiment, in order to further improve the cleaning effect on the cylinder 1, refer to Figure 1 As shown, at least one spray hole 15 is also provided on the cylinder 1, and the foam generator 4 also includes a spray nozzle 44, which is connected to the spray hole 15. The spray hole 15 can increase the connection between the cylinder 1 and the water pump 33. The spray hole 15 and the bubble hole 13 spray liquid into the cylinder 1 simultaneously, which can improve the cleaning effect of the cylinder 1.
[0036] Specifically, when multiple spray holes 15 are provided, the multiple spray holes 15 are respectively located at different positions of the cylinder 1, thereby realizing cleaning of the cylinder 1 at different positions.
[0037] When using the water circulation cleaning system of the present invention for water circulation cleaning, there are two cleaning modes: cylinder cleaning and drying unit cleaning, which can be operated independently or synchronously.
[0038] Reference Figure 5As shown, during the cleaning of the cylinder 1: water is introduced into the cylinder 1 through the external water supply pipe at the water inlet 11. The inlet 11 receiving water constitutes the first cleaning of the cylinder 1. After the first cleaning, the water flows out from the drain hole 12 into the drain pump 31. At this time, the drain pump 31 is turned off, and the water is drawn from the drain pump 31 by the water pump 33, flows through the feeding module 32, and then re-enters the cylinder 1 through the bubble hole 13, thus achieving a second cleaning of the cylinder 1. During this cleaning process, if a deep cleaning of the drum 1 is required, disinfectant and laundry detergent can be added to the feeding module 32. Foam is formed through the bubble hole 13 and discharged into the drum 1 through the bubble hole 13 and the spray hole 15. After the drum 1 is cleaned a second time, the water flow is discharged again from the drain hole 12 into the drain pump 31. At this time, the drain pump 31 is turned off, thereby realizing the circulation cleaning. After the drum 1 is cleaned multiple times, the drain pump 31 is turned on, and the water flow is discharged into the external drain pipe 5, completing the cleaning of the drum 1.
[0039] Specifically, in order to enable the independent operation of the cleaning of the cylinder 1 and the cleaning of the drying unit 2, a one-way valve 23 is provided between the water pump 33 and the water inlet circuit 21. When the cylinder 1 is being cleaned, the one-way valve 23 is closed, and when the drying unit 2 needs to be cleaned, the one-way valve 23 is opened, and water is introduced into the water inlet circuit 21.
[0040] Reference Figure 6 As shown, when cleaning the drying unit 2: water is introduced into the cylinder 1 through the water inlet 11 via the external water supply pipe, and the water flows out from the drain hole 12 into the drain pump 31. At this time, the drain pump 31 is turned off, and the water pump 33 draws the water from the drain pump 31, flows through the feeding module 32, and enters the drying unit 2 from the water inlet circuit 21 to clean the drying unit 2. The water flowing through the drying unit 2 is discharged from the water outlet circuit 22 into the drain pump 31. At this time, the drain pump 31 is turned off, thereby realizing the circulation cleaning. After cleaning the drying unit 2 multiple times, the drain pump 31 is turned on, and the water is discharged into the external drain pipe 5, completing the cleaning of the drying unit 2.
[0041] If a deep cleaning of the drying unit 2 is required during this cleaning process, a bactericide and laundry detergent can be added to the feeding module 32 to complete the deep cleaning.
[0042] In the actual cleaning process, the water used to clean the cylinder 1 can be pumped back into the drying unit 2 by the water pump 33 to achieve secondary utilization, thereby further reducing the waste of water resources.
[0043] The present invention also discloses a washer-dryer combo machine. The water circulation cleaning system is applied in the washer-dryer combo machine. Before realizing the water circulation cleaning function, it is also necessary to ensure that the washing and drying functions in the washer-dryer combo machine can be used normally.
[0044] Specifically, the washer-dryer of the present invention uses the above-mentioned water circulation cleaning system for washing as follows: water is introduced into the drum 1 through the external water supply pipe at the water inlet 11, the drum 1 is turned on to start washing, the feeding module 32 is filled with bactericidal liquid and laundry detergent, and the water is pumped into the foam generator 4 by the water pump 33 to generate foam, which is then added into the drum 1 through the bubble hole 13 and the spray hole 15 to achieve the washing of clothes;
[0045] During the washing process, the high concentration of laundry detergent settles to the bottom of the drum 1 and is discharged from the drain hole 12 at the bottom. At this time, the drain pump 31 is turned off and the water pump 33 continues to work, continuously running the high concentration of laundry detergent to the spray hole 15 and the bubble hole 13, continuously spraying out bubbles, thereby forming a washing circuit.
[0046] After washing is completed, the drain pump 31 is turned on, and the wastewater after washing is discharged into the external drain pipe 5 by the pump 31.
[0047] Specifically, the washing and drying machine of the present invention uses the above-mentioned water circulation cleaning system for drying as follows: the water in the drum 1 is discharged, the drying unit 2 is running, the one-way valve 23 between the drying unit 2 and the water pump 33 is closed, and the condensate formed during the drying process is discharged by the drain pump 31 through the water outlet circuit 22 to the external drain pipe 5.
[0048] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
