[0060] In order to more clearly explain the above-mentioned purposes, features and advantages of the present application, the specific implementation methods of the present application are described in detail in this section in conjunction with the accompanying drawings. In addition to the various implementation methods described in this section, the present application can also be implemented in other different ways. Without violating the spirit of the present application, those skilled in the art can make corresponding improvements, deformations and substitutions, so the present application is not limited by the specific embodiments disclosed in this section. The scope of protection of the present application shall be subject to the claims.

[0061] like Figures 1 to 12 As shown, an embodiment of the present application proposes a clothing cleaning device, which includes a ventilation box assembly 100, a water bucket 200 and an additive delivery system. The water bucket 200 can hold water for cleaning clothes. The ventilation box assembly 100 is formed with a accommodating space P, which can hold liquid (e.g., additives and water). The additive box 400 can store one or more additives. The temporary storage chamber 300 and the additive box 400 can be arranged below the water bucket 200, and the ventilation box assembly 100 can be arranged above the water bucket 200.

[0062] The clothes cleaning device may be, for example, a drum washing machine, and a front side of the drum washing machine in the front-rear direction X may have a clothes loading opening.

[0063] The additive delivery system includes a temporary storage chamber 300, an additive box 400, a flow diversion mechanism, a pump 6, a main flow channel L1 and a branch flow channel L2.

[0064] The additive box 400 is used to hold additives, and the temporary storage chamber 300 is used to temporarily store and / or dilute additives. The temporary storage chamber 300 is directly or indirectly connected to the first water inlet valve FV1 to pass water into the temporary storage chamber 300 to dilute the additive. The additive box 400 and the temporary storage chamber assembly 300 are connected via an additive valve, and the additive valve is used to control the on-off of the flow path between the additive box 400 and the temporary storage chamber assembly 300.

[0065] like Figure 7 and Fig. 9 As shown, the temporary storage chamber 300 is provided with a temporary storage chamber liquid outlet 301 and a temporary storage chamber exhaust port 302. The additive box 400 is provided with a liquid channel 401 and a gas channel 402.

[0066] The two ends of the liquid channel 401 are respectively provided with an additive box liquid inlet 4011 and an additive box liquid outlet 4012, and the two ends of the gas channel 402 are respectively provided with an additive box air inlet 4021 and an additive box air outlet 4022. The liquid channel 401 and the gas channel 402 extend along the front-to-back direction X of the laundry cleaning device as a whole.

[0067] The temporary storage chamber liquid outlet 301 is connected to the additive box liquid inlet 4011, and the temporary storage chamber exhaust port 302 is connected to the additive box air inlet 4021. One end of the gas channel 402 (i.e., the additive box air inlet 4021) can be connected to the temporary storage chamber exhaust port 302, and the other end of the gas channel 402 (i.e., the additive box air outlet 4022) can be connected to the accommodating space P of the ventilation box assembly 100 through the temporary storage chamber air pressure tube 12.

[0068] The pump 6 is used to pump the additive in the additive chamber 400 to the temporary storage chamber 300 . The pump 6 may be located at the rear side of the temporary storage chamber 300 , so that the pump 6 is easy to maintain.

[0069] By using the additive box 400 to form the liquid channel 401 and the gas channel 402, the temporary storage chamber liquid outlet 301 and the temporary storage chamber exhaust port 302 located on the rear side of the clothing cleaning device can be transferred to the front of the clothing cleaning device without the need for independently set up pipelines, which facilitates the arrangement of (other) pipelines, can fully utilize the space, and make the structure compact.

[0070] like Fig. 9 As shown, the additive box 400 includes an additive box body 403 and a washing plate 404. The additive box body 403 is used to hold additives. The additive box body 403 and the washing plate 404 are connected together to form a liquid channel 401 and a gas channel 402. In the left-right direction Y of the clothes cleaning device, the washing plate 404 can be located on one side of the additive box body 403. The liquid channel 401 and the gas channel 402 are enclosed by the additive box body 403 and the washing plate 404, which can make manufacturing easy and low-cost.

[0071] The liquid channel 401 and the gas channel 402 are separated, and for the portions of the liquid channel 401 and the gas channel 402 extending along the front-rear direction X, the gas channel 402 may be located above the liquid channel 401 in the up-down direction Z of the laundry cleaning device. The liquid channel 401 and the gas channel 402 are separated so that the liquid and the gas are transported separately, and even if the liquid channel 401 leaks, the liquid will not leak into the gas channel 402.

[0072] The additive box liquid outlet 4012 and / or the additive box gas outlet 4022 may be located in the additive box body 403 or the wash plate 404. Providing the additive box liquid outlet 4012 or the additive box gas outlet 4022 in the additive box body or the wash plate 404 facilitates the formation.

[0073] The diversion mechanism includes an inlet channel 53, a first outlet channel 51, and a second outlet channel 52. The first outlet channel 51 and the second outlet channel 52 are both connected to the inlet channel 53. The first outlet channel 51 is connected to the main channel L1, which is connected to the temporary storage chamber 300. The main channel L1 is connected to at least one additive receiving portion of the additive box 400 described later. The second outlet channel 52 is connected to the branch channel L2, which is connected to the temporary storage chamber 300 without passing through the additive box 400. Figure 4 In FIG. 1 , a solid arrow indicates the main flow channel L1 , and a dotted arrow indicates the main flow channel L2 .

[0074] When the water inlet flow rate is large, the diverter valve 5 can divert a portion of the water inlet through the branch channel L2 and temporarily store it in the temporary storage chamber 300 to prevent overflow when the water inlet flow rate is large.

[0075] Optionally, the diverter mechanism may be a diverter valve 5, which includes an inlet channel 53, a first outlet channel 51 and a second outlet channel 52. Further, the diverter mechanism (diverter valve 5) is configured so that the flow rate of the first outlet channel 51 is greater than the flow rate of the second outlet channel 52.

[0076] Reference Figure 5 and Fig.10 Specifically, the first water outlet channel 51 may be provided with a first one-way valve, which can prevent the fluid from flowing from the first water outlet channel 51 to the water inlet channel 53. The second water outlet channel 52 is provided with a second one-way valve 521, which can prevent the fluid from flowing from the second water outlet channel 52 to the water inlet channel 53. The opening resistance of the first one-way valve is smaller than the opening resistance of the second one-way valve 521. When water flows into the water inlet channel 53, the first one-way valve and the second one-way valve 521 can be opened under the action of water pressure, and the opening degree of the first one-way valve is larger than the opening degree of the second one-way valve 521, so that the flow rate of the first water outlet channel 51 is larger than the flow rate of the second water outlet channel 52.

[0077] In another possible implementation, the first water outlet channel 51 may not be provided with a one-way valve, and the second water outlet channel 52 may be provided with a second one-way valve 521, and the second one-way valve 521 can prevent the fluid from flowing from the second water outlet channel 52 to the water inlet channel 53. When water flows into the water inlet channel 53, the water flow can directly flow to the first water outlet channel 51, and the second one-way valve 521 can be opened under the action of water pressure to flow to the second water outlet channel 52, so that the flow rate of the first water outlet channel 51 is greater than the flow rate of the second water outlet channel 52.

[0078] Optionally, the first water outlet channel 51 may be located below the water inlet channel 53 , and the second water outlet channel 52 may be located above the water inlet channel 53 , so that under the action of gravity, the flow rate of the first water outlet channel 51 may be greater than the flow rate of the second water outlet channel 52 .

[0079] like Fig.10 As shown, in the water flow direction, the diverter valve 5 can be located on the upstream side of the additive box 400. By adjusting the flow distribution of the two water outlet channels (i.e., the first water outlet channel 51 and the second water outlet channel 52) of the diverter valve 5, the flow of water for flushing the additive (i.e., the water in the main channel L1) and the flow of water diverted by the branch channel L2 can be controlled.

[0080] It is understood that in other possible embodiments, the flow diversion mechanism may be a three-way pipe, which may include a water inlet channel, a first water outlet channel, and a second water outlet channel. The cross-sectional area of ​​the first water outlet channel is greater than the cross-sectional area of ​​the second water outlet channel, and the water flow rates of the first water outlet channel and the second water outlet channel are controlled by the cross-sectional areas of the channels, so that the flow rate of the first water outlet channel is greater than the flow rate of the second water outlet channel.

[0081] like Figures 3 to 5 As shown, the temporary storage chamber 300 includes an S-shaped channel, the S-shaped channel is connected to the branch channel L2, and the downstream end of the S-shaped channel and the downstream end of the main channel L1 meet near the temporary storage chamber liquid outlet 301 of the temporary storage chamber 300. The S-shaped channel can prevent the liquid (additive) in the main channel L1 from flowing back or flowing to other locations through the branch channel L2.

[0082] like Figure 4 As shown, the pump 6 includes a pump inlet 61 and a pump outlet 62. Inside the temporary storage chamber 300, the bottom surface between the pump outlet 62 and the temporary storage chamber liquid outlet 301 includes an inclined surface, and the temporary storage chamber liquid outlet 301 is located at the lower end of the inclined surface. The additive can be smoothly flushed to the temporary storage chamber liquid outlet 301 and flow out, preventing the additive from remaining in the temporary storage chamber and keeping the temporary storage chamber clean and sanitary.

[0083] The additive box 400 may include a plurality of additive containing parts, and the additive containing parts and the storage chamber assembly 300 are connected via an additive valve, and the additive valve is used to control the on-off of the flow path between the additive containing part and the temporary storage chamber assembly 300. Each additive containing part may be connected to an additive valve. The additive valve is located at the rear side of the temporary storage chamber 300, so that the additive valve can be easily maintained. Each additive containing part can be used to contain an additive, for example, multiple additive containing parts can respectively contain detergent, softener, care agent, etc.

[0084] Further, the plurality of additive containing parts at least include a first additive box and a second additive box, and the additive valve includes a first additive valve 7 and a second additive valve 8. The first additive box may be connected to the first additive valve 7, which may be a one-way valve, and the first additive valve 7 is connected to the first water outlet channel 51. The second additive box may be connected to the second additive valve 8, which may be a three-way valve.

[0085] There is no need to set a three-way valve for each additive container. The one-way valve has a simpler structure and lower cost than the three-way valve. When the second additive box 8 is cut off, the pump 6 can be used to form a negative pressure to open the one-way valve and suck the additive in the first additive box.

[0086] In this embodiment, the plurality of additive containing parts further include a third additive cartridge 9, and the additive valve further includes a third additive valve 9. The third additive valve 9 is a three-way valve, and the second additive valve 8 and the third additive valve 9 are connected together.

[0087] The one-way valve has a simpler structure and lower cost than the three-way valve. When the second additive box 8 and the third additive box 9 are disconnected, the pump 6 can be used to form a negative pressure to open the one-way valve and suck out the additive in the first additive box.

[0088] The vent box assembly 100 connects the accommodating space P with the outside atmosphere through the exhaust port. One end of the water bucket air pressure pipe 11 can be connected to the upper part of the accommodating space P, and the other end of the water bucket air pressure pipe 11 is used to connect to the water bucket 200 of the clothes cleaning device. Thus, the water bucket 200 can be connected to the atmosphere through the vent box assembly 100 through the water bucket air pressure pipe 11.

[0089] One end of the temporary storage chamber air pressure pipe 12 can be connected to the upper part of the accommodation space P, and the other end of the temporary storage chamber air pressure pipe 12 is connected to the temporary storage chamber 300 through the gas channel 402. Thus, the temporary storage chamber 300 can be connected to the atmosphere through the ventilation box assembly 100 through the temporary storage chamber air pressure pipe 12.

[0090] After water enters the accommodating space P of the ventilation box assembly 100 (for example, water carried by foam), water can be prevented or reduced from entering the water bucket air pressure tube 11 and the temporary storage chamber air pressure tube 12, thereby affecting the ventilation effect of the water bucket 200 and the temporary storage chamber 300.

[0091] like Fig.11 and Fig.12 As shown, the ventilation box assembly 100 includes a venturi tube 3, and the venturi tube 3 includes a water inlet 32, a liquid outlet 31 and an additive inlet 33. The additive inlet 33 is arranged at the contraction throat of the venturi tube 3, and the additive inlet 33 can be connected to the temporary storage chamber 300 through the additive inlet pipe 15 and the liquid channel 402. The liquid outlet 31 is connected to the bucket 200 through the water inlet pipe 34, and the water inlet pipe 34 can be connected to the front side and the upper side of the bucket 200. The water inlet 32 ​​can be connected to the second water inlet valve FV2, and the faucet can supply water to the venturi tube 3 when the second water inlet valve FV2 is opened.

[0092] When water flows from the water inlet 32 ​​to the liquid outlet 31, negative pressure will be formed at the contraction throat of the venturi tube 3. The additive in the temporary storage chamber 300 can be sucked into the venturi tube 3 by the negative pressure formed by the venturi tube 3 and mixed and diluted with water, and then supplied to the water bucket 200 through the water inlet pipe 34. The present application uses a simple structure to achieve the absorption and dilution of additives.

[0093] In the vertical direction Z, the venturi tube 3 can be located above the pump 6. By providing the pump 6 and the venturi tube 3 as two extraction mechanisms to deliver the additive to the water bucket 200, the pressure of the extraction mechanism can be reduced, the service life of the extraction mechanism can be increased, and the risk of water leakage of the extraction mechanism can be reduced compared to using only one extraction mechanism. The pump 6 only takes on the operation of extracting the additive without taking on the water supply operation. The pump 6 with higher precision and lower pressure can be used, which can improve the accuracy of the additive delivery.

[0094] The additive and water can be put into the upper surface of the clothes from the drum opening on the front side of the clothes cleaning device through the water inlet pipe 34, and the washing effect is good. The water enters the water bucket 200 from the liquid outlet 31 of the venturi tube 3 through the water inlet pipe 34, and the effect of high-pressure water spraying can be achieved, which is conducive to foaming and has a good spraying effect.

[0095] In the front-to-back direction X of the laundry cleaning device, the additive inlet 33 (connected to the additive inlet pipe 15) can be located at the front side of the ventilation box assembly 100. This can make the additive inlet pipe 15 located at the front side of the laundry cleaning device shorter and occupy less space.
