[0026] Exemplary embodiments will now be described in detail, examples of which are illustrated in the drawings. In the following description, unless otherwise specified, the same reference numerals in different drawings refer to the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. These are merely examples of apparatus and methods consistent with some aspects of the present disclosure, as set forth in the claims.

[0027] The embodiments described in the following examples of the present disclosure are not intended to represent all embodiments consistent with the present disclosure, but are merely examples of devices and methods consistent with some aspects of the present disclosure, as set forth in the claims.

[0028] It should be noted that all acquisition signals, information or data operations in this disclosure are subject to the data protection regulatory policies of the respective country and are performed only when authorized by the applicable device owner.

[0029] As shown in FIGS. 1 to 3, an exemplary embodiment of the present disclosure provides a water supply system for a washing machine that is applicable to a clothing treatment device, and the clothing treatment device may be a single-drum washing machine, a single-drum dryer, a single-drum combined washing and drying machine, a double-drum washing machine, a double-drum dryer, a double-drum combined washing and drying machine, etc.

[0030] Specifically, the water supply system of the washing machine according to the present disclosure includes a first cylinder 3000 and a first water supply pipe 4100. The first cylinder 3000 accommodates clothes, and is provided with an exhaust pipe 3100. The water outlet of the first water supply pipe 4100 communicates with the exhaust pipe 3100, so that foam that has overflowed from the first cylinder 3000 into the exhaust pipe 3100 can be pushed back into the first cylinder 3000 in the opposite direction.

[0031] The cylindrical body is usually provided with a water inlet, a water outlet, and an exhaust port. The water inlet is used to inject water into the cylindrical body, and the water outlet is used to discharge wastewater after rinsing outside the washing machine. Some gas generated during operation of the washing machine is discharged outside the washing machine through the exhaust port. An exhaust pipe 3100 communicates with the exhaust port. The exhaust pipe 3100 may be injection molded integrally with the first cylindrical body 3000, or an independent pipe may be used.

[0032] The water outlet of the first water supply pipe 4100 may be connected to any position in the exhaust pipe 3100, as long as it can push the bubbles in the exhaust pipe 3100 back in the opposite direction to the first cylindrical body 3000. Note that the "reverse direction" here means the direction in which gas or bubbles overflow into the exhaust pipe 3100, i.e., the direction in which the gas is discharged is defined as from the inside to the outside, and the reverse direction here, i.e., the direction from the outside to the inside.

[0033] As the water flowing out from the first water supply pipe 4100 is pushed back in the opposite direction to the first cylindrical body 3000, some of the bubbles are struck by the water flow in the opposite direction and dissolved. The bubbles that are partially returned to the first cylindrical body 3000 are blocked by the water flow constantly pushing back in the opposite direction and are unable to overflow into the exhaust pipe 3100, so they gradually dissolve within the first cylindrical body 3000, and the remaining bubbles are discharged out of the washing machine with the wastewater in the first cylindrical body 3000 through the drain pipe.

[0034] The invention according to the embodiments of the present disclosure has the following beneficial effects: The water supply system of the washing machine according to the present disclosure is provided with a first water supply pipe 4100, and the water outlet of the first water supply pipe 4100 is connected to the exhaust pipe 3100. When some foam overflows from the first tubular body 3000 into the exhaust pipe 3100, in order to prevent the foam from continuing to overflow outside the washing machine, the water outflowing from the first water supply pipe 4100 is directed into the exhaust pipe 3100, so that the foam is returned in the opposite direction into the first tubular body 3000, and pushed back in the opposite direction, and the foam can be removed again within the first tubular body 3000. Even if the remaining foam is blocked by the water pushed back in the opposite direction, it will not overflow into the exhaust pipe but will be subsequently discharged from the drain pipe, thereby removing the foam and preventing it from polluting the indoor environment.

[0035] Any configuration or method that can guide water from the first water supply pipe 4100 into the first cylindrical body 3000 while minimizing overflow from the exhaust pipe 3100 can be applied to the present disclosure. In some embodiments, as shown in FIG. 3 , a water guide structure 3110 is provided in the exhaust pipe 3100 to at least partially guide water discharged from the first water supply pipe 4100 into the first cylindrical body 3000. The water guide structure 3110 may be, for example, a guide slope. In other embodiments, the exhaust pipe 3100 may be installed at an angle with its lower end located on the first cylindrical body 3000 side, which is also advantageous for guiding water discharged from the first water supply pipe 4100 into the first cylindrical body 3000. In still other embodiments, a water guide method in which the water guide structure 3110 and the exhaust pipe 3100 are installed at an angle with their lower end located on the first cylindrical body 3000 side can be combined within the exhaust pipe 3100. In addition, the water outlet of the first water supply pipe 4100 may be installed facing the first cylindrical body 3000, i.e., water may be drained directly from the first water supply pipe 4100 toward the first cylindrical body 3000, which is also advantageous for achieving the purpose of pushing overflowing foam back into the first cylindrical body 3000.

[0036] 1, the water supply system of the washing machine further includes a second water supply pipe 4200, the water outlet of which is connected to the water inlet of the first cylinder 3000, and the water inlet of the first water supply pipe 4100 is connected to the second water supply pipe 4200. The second water supply pipe 4200 is used to inject water into the first cylinder 3000. The water inlet of the first water supply pipe 4100 is connected to the second water supply pipe 4200, so that the first water supply pipe 4100 can be considered as a branch pipe drawn from the second water supply pipe 4200. That is, when water is injected into the first cylinder 3000, some of the water in the second water supply pipe 4200 can simultaneously enter the first water supply pipe 4100. This method of introducing a branched water supply pipe has a simpler wiring structure than the method of drawing a single pipe separately from the water supply valve to the exhaust pipe 3100, and is advantageous for optimizing the internal space layout of the washing machine.

[0037] Furthermore, a three-way valve 4300 may be provided in the second water supply pipe 4200, and the water supply port of the first water supply pipe 4100 is connected to the three-way valve 4300. By providing the three-way valve 4300, the first water supply pipe 4100 can be selectively turned on and off, that is, the three-way valve 4300 can be turned on as needed, and for example, when it is detected that foam is not overflowing into the exhaust pipe 3100, the first water supply pipe 4100 can be closed to conserve water.

[0038] The water supply system for a washing machine according to the present disclosure can be applied to a single-drum washing machine, and preferably also to a double-drum washing machine. Taking a double-drum washing machine as an example, the water supply system for a washing machine according to the present disclosure further includes a second cylinder (not shown), where the diameter of the first cylinder 3000 is smaller than that of the second cylinder. That is, the first cylinder 3000 is a small cylinder, and the second cylinder is a large cylinder. Large cylinders generally have a large diameter and a large volume, allowing most of the foam to be self-removed within the cylinder or discharged through the drain pipe. In contrast, small cylinders have a relatively small volume, so the amount of foam that can be self-removed is limited, increasing the risk of foam overflowing from the exhaust pipe 3100. The water supply system for a washing machine according to the present disclosure advantageously solves the problem of the small cylinder.

[0039] As shown in FIG. 1 , the exhaust pipe 3100 may be located on the side of the first cylinder 3000. The term "side" here differs from the related art, in which the exhaust pipe 3100 is located on the top or bottom of the cylinder. By locating the exhaust pipe 3100 on the side of the first cylinder 3000, space can be saved on the top or bottom of the first cylinder 3000, optimizing the design height of the washing machine. Furthermore, since the first and second cylinders 3000 and 3000 are typically arranged one above the other in a washing machine, locating the exhaust pipe 3100 on the side is advantageous for avoiding interference between the upper and lower cylinders. However, considering the relatively small volume of the first cylinder 3000, locating the exhaust pipe 3100 on the side of the first cylinder 3000, i.e., the low exhaust position, may exacerbate foam overflow from the exhaust pipe 3100. Therefore, by using the first water supply pipe 4100 to push the foam in the exhaust pipe 3100 back into the first cylinder 3000 in the opposite direction, the design space inside the washing machine can be optimized while avoiding the risk of foam overflowing from the exhaust pipe 3100.

[0040] In an embodiment in which the washing machine is a double-drum washing machine, the water supply system of the washing machine may further include a third water supply pipe 4400, and the water outlet of the third water supply pipe 4400 may be connected to the water supply port of the second cylinder. That is, by providing one water supply pipe for each of the first cylinder 3000 and the second cylinder, the water supply to the first cylinder 3000 and the second cylinder can be controlled independently.

[0041] As shown in Fig. 1, the water supply system of the washing machine according to the present disclosure may further include a water supply box 4500, which can be regarded as a device for distributing water. Specifically, referring also to Fig. 2, the inlet of the water supply box 4500 is connected to a water supply valve via a pipe, and the water supply ports of the second water supply pipe 4200 and the third water supply pipe 4400 are connected to the outlet of the water supply box 4500, respectively. During operation, the water supply valve is opened, and water enters the water supply box 4500 from the water supply valve. The water is then distributed by the water supply box 4500 to the second water supply pipe 4200 and the third water supply pipe 4400, respectively. The water that has entered the second water supply pipe 4200 further enters the first water supply pipe 4100 by controlling the three-way valve 4300.

[0042] The water supply box 4500 plays the role of an integrated pipeline. Specifically, by integrating the water pipes that are installed independently into the water supply box 4500, the layout of the internal pipelines of the washing machine can be further optimized. Compared with assembling multiple water pipes, the integrated water supply box 4500 can save the number of installed water pipes, optimize the layout, and is advantageous in improving the overall assembly efficiency of the washing machine.

[0043] The design of integrating multiple water pipes into water supply box 4500 can be realized by providing multiple water channels inside water supply box 4500. For example, by providing multiple ribs inside water supply box 4500, the number and orientation of the ribs can be rationally designed to form water channels. Specifically, water supply box 4500 is provided with a first water channel 4510 communicating with the water supply valve, a second water channel 4520 communicating with first cylindrical body 3000, and a third water channel 4530 communicating with the second cylindrical body.

[0044] The water supply box 4500 may be designed so that the water in the first water channel 4510 directly enters the second water channel 4520 and the third water channel 4530, or the water supply box 4500 may be designed so that the water in the first water channel 4510 first enters an input box containing the washing liquid, and then the mixture of the washing liquid and water enters the second water channel 4520 and the third water channel 4530, respectively. The latter method is applied to a washing machine having an input box.

[0045] 2, the water supply box 4500 is provided with a first water inlet port 4511 and a first water outlet port 4512 communicating with the first water passage 4510, a second water inlet port 4521 and a second water outlet port 4522 communicating with the second water passage 4520, and a third water inlet port 4531 and a third water outlet port 4532 communicating with the third water passage 4530. The first water inlet port 4511 communicates with the water supply valve, the first water outlet port 4512 communicates with an input box that stores washing liquid, the second water inlet port 4521 and the third water inlet port 4531 communicate with the input box, the second water outlet port 4522 communicates with the first cylindrical body 3000, and the third water outlet port 4532 communicates with the second cylindrical body.

[0046] The input box contains detergent such as laundry liquid. The water in the first water channel 4510 flows into the input box, and the water supply pipe has a closed structure. The water in the input box is mixed with the laundry liquid and flows into the second water channel 4520 and the third water channel 4530 under the pressure of water, and then enters the first cylinder 3000 and the second cylinder, respectively.

[0047] The water outlet of the first water supply pipe 4100 may be directly connected to the exhaust pipe 3100, or may be indirectly connected to the exhaust pipe 3100 via a drain vent box 3200. Specifically, as shown in FIGS. 1 and 4 , the water supply system of the washing machine of the present disclosure further includes a drain vent box 3200, which includes a case 3210 and a ventilation chamber 3220 and a drain chamber 3230 that are provided independently of each other inside the case 3210, and the water outlets of the exhaust pipe 3100 and the first water supply pipe 4100 respectively communicate with the ventilation chamber 3220. The drain vent box 3200 of the present disclosure has an integrated structure for drainage and ventilation, a compact structural design, a high degree of integration, and effectively reduces the number of parts and costs. The bubbles overflow into the ventilation chamber 3220 through the exhaust pipe 3100, and by connecting the water outlet of the first water supply pipe 4100 to the ventilation chamber 3220, the purpose of pushing the bubbles back into the first cylinder 3000 in the opposite direction is achieved.

[0048] In some embodiments, referring also to FIG. 5, the case 3210 may be provided with an intake port 3211 of the ventilation chamber 3220, a first water supply pipe port 3212, and an exhaust port 3213, respectively, wherein the exhaust port 3213 is connected to the external environment, the intake port 3211 is connected to the exhaust pipe line 3100, the first water supply pipe port 3212 is connected to the first water supply pipe 4100, and water discharged from the first water supply pipe port 3212 can flow back into the first cylinder body 3000 through the intake port 3211. The solid arrows in Figure 5 indicate the exhaust direction of the first cylinder 3000, i.e., from the first cylinder 3000 through the exhaust pipe 3100, into the ventilation chamber 3220, and finally discharged into the room through the exhaust port 3213. The dashed arrows indicate the flow direction of water discharged from the first water supply pipe 4100, i.e., from the first water supply pipe 4100, into the ventilation chamber 3220 through the first water supply pipe port 3212, and then back into the first cylinder 3000 in the opposite direction through the intake port 3211.

[0049] Here, the ventilation chamber 3220 may include a first ventilation chamber 3221 and a second ventilation chamber 3222 that communicate with each other, where the first ventilation chamber 3221 communicates with the exhaust port 3213, and the second ventilation chamber 3222 communicates with the intake port 3211 and the first water supply pipe port 3212, respectively, and the second ventilation chamber 3222 is formed by extending downward from the side of the first ventilation chamber 3221. Specifically, the first ventilation chamber 3221 and the second ventilation chamber 3222 are configured in a serpentine shape, i.e., so that gas flows from bottom to top during exhaust and from top to bottom during water supply, thereby minimizing water overflow from the exhaust port 3213 into the room and pushing it back into the exhaust pipe 3100 by the action of gravity.

[0050] In some other embodiments, as shown in FIG. 6, the case 3210 is provided with a first water inlet 3214, a second water inlet 3215 and a drain outlet 3216, and the drain chamber 3230 is provided with a first drain channel 3231 and a second drain channel 3232 that are connected to each other, with the upstream end of the first drain channel 3231 connected to the first water inlet 3214, the downstream end of the first drain channel 3231 connected to the drain outlet 3216, the upstream end of the second drain channel 3232 connected to the second water inlet 3215, and the downstream end of the second drain channel 3232 connected to the downstream end of the first drain channel 3231 and connected to the drain outlet 3216.

[0051] In this embodiment, the first drainage channel 3231 includes a plurality of channel segments that communicate with each other, thereby forming a serpentine path shape to meet drainage needs. However, the present disclosure does not limit the specific shape of the first drainage channel 3231. Preferably, the first drainage channel 3231 includes a first channel segment 32311 and a second channel segment 32312, wherein the upstream end of the first channel segment 32311 is connected to the first water inlet 3214, the downstream end of the first channel segment 32311 is connected to the upstream end of the second channel segment 32312, the downstream end of the second channel segment 32312 is connected to the drain outlet 3216, and the downstream end of the second drainage channel 3232 is connected to the downstream end of the second channel segment 32312 and then to the drain outlet 3216.

[0052] That is, in this embodiment, the first channel segment 32311 and the second channel segment 32312 collectively define a U-shaped passageway. After water flows into the first drain channel 3231 from the first water inlet 3214, it first passes through the first channel segment 32311, then flows into the second channel segment 32312, and is then discharged through the drain port 3216. When water flows into the second drain channel 3232 from the second water inlet 3215, the water at the downstream end of the second drain channel 3232 merges with the water downstream of the second channel segment 32312 and is discharged through the drain port 3216.

[0053] According to a second embodiment of the present disclosure, there is further provided a washing machine including the water supply system of any one of the above embodiments and having all the beneficial effects thereof, and the description thereof is omitted here. Preferably, the washing machine may be a double-drum washing machine, and the first cylinder 3000 may be a small cylinder.

Thus, a "first" or "second" feature may explicitly or implicitly include at least one of the feature. In the present specification, "plurality" means at least two, e.g., two, three, etc., unless otherwise specified.

[0059] It should be understood that relative terms such as "above," "top," "below," and "bottom" are used herein to describe the relationship between one element and another element shown in the figures. Such spatially relative terms are intended to encompass different orientations in use or operation of the device, in addition to the orientation depicted in the figures. For example, if the device in the figures were inverted, an element would be described as being "below" or "below" the other element relative to "above" or "top" of the other element. Thus, depending on the spatial orientation of the device, the term "above" encompasses both an orientation of above and below. The device may have other orientations (e.g., rotated 90 degrees or other orientations), and the spatial terms used herein should be interpreted accordingly.

[0060] It should be noted that the term "exemplary" is used herein to indicate an example, instance, or diagram. Any aspect or design described herein as "exemplary" is not necessarily to be understood as advantageous over other aspects or designs. Rather, the term's exemplary presentation is used to express a concept. As used herein, the term "or" is intended to indicate an inclusive "or," rather than an exclusive "or." That is, "X Application A or B" is intended to indicate any arrangement of the natural inclusive arrangement, unless otherwise specified or clear from the context. That is, "X Application A or B" is satisfied in any instance if there is X Application A; X Application B; or both X Applications A and B. Additionally, the articles "a" and "one" used herein and in the claims should be understood to indicate "one or more," unless otherwise specified or clearly indicated by the context.

[0061] Similarly, although the present disclosure has been described with respect to one or more embodiments, equivalent variations and modifications will occur to those skilled in the art after reading and understanding the present specification and drawings. The present disclosure includes all such modifications and variations and is limited only by the scope of the claims. In particular, the various functions performed by the components (e.g., elements, resources, etc.) described above correspond to any component (functionally equivalent) that realizes the specific function of the component, etc., unless otherwise expressly stated or clearly believed to be otherwise in principle. Furthermore, although a particular feature of the present disclosure is disclosed with respect to one of several embodiments, such feature may be combined with one or more other features in other implementations as may be advantageous for any or particular applications. Furthermore, when used in this specification or claims, with respect to "comprises," "possessing," "having," "having," "having," or variations thereof, such terms are intended to be inclusive as analogous forms of the term "comprises."

[0062] Those skilled in the art will be able to easily devise other embodiments of the present disclosure after reading the specification and practicing the invention disclosed herein. This application is intended to cover any variations, uses, or adaptations of the present disclosure, which variations, uses, or adaptations follow the general principles of the present disclosure and include means well known in the art or commonly used in the art that are not disclosed in the present disclosure. The presently disclosed embodiments are to be considered in all respects as illustrative and not restrictive.
