The following description refers to the accompanying drawings in which the same numbers in different drawings represent the same or similar elements unless otherwise represented. The implementations set forth in the following description of exemplary embodiments do not represent all implementations consistent with the present disclosure. Instead, they are merely examples of apparatuses and methods consistent with some aspects related to the present disclosure as recited in the appended claims.
The implementations described in some embodiments of the present disclosure below do not represent all implementations consistent with the present disclosure. Instead, they are only examples of apparatuses and methods consistent with some aspects of the present disclosure as recited in the appended claims.
It should be noted that all actions of obtaining signals, information or data in the present disclosure are carried out under the premise of complying with the corresponding data protection regulations and policies of the country of residence and with the authorization given by the owner of the corresponding apparatus.
During the rinsing process of clothes in the washing machine, detergent and other cleaning materials are usually added. If the added detergent is abnormal, such as too much, it is easy to cause high foam problems. If the high foam is not eliminated in time, it may be discharged to the outside of the washing machine through the exhaust port and pollute the indoor environment.
As shown in FIGs. 1 to 3, the exemplary embodiments of the present disclosure provide a water inlet system of a washing machine, which can be applied to a clothing processing equipment, and the clothing processing equipment may be a single-drum washing machine, a single-drum dryer, a single-drum washer-dryer, a double-drum washing machine, a double-drum dryer, a double-drum washer-dryer, etc.
Specifically, the water inlet system of the washing machine provided by the present disclosure includes a first barrel 3000 and a first water inlet pipe 4100. The first barrel 3000 is used to accommodate clothes, and the first barrel 3000 is provided with an exhaust pipeline 3100. The water outlet of the first water inlet pipe 4100 is communicated with the exhaust pipeline 3100, and can reversely flush the foam overflowing from the first barrel 3000 into the exhaust pipeline 3100 back into the first barrel 3000.
Usually, the barrel is provided with a water inlet, a water outlet and an exhaust port. The water inlet is used to inject water into the barrel, the water outlet is used to discharge the waste water after rinsing to the outside of the washing machine, and part of the gas generated during the operation of the washing machine will be discharged from the exhaust port to the outside of the washing machine. The exhaust pipeline 3100 is communicated with the exhaust port. The exhaust pipeline 3100 can be integrally injection molded with the first barrel 3000, or a separate pipeline can be used.
The water outlet of the first water inlet pipe 4100 can be communicated with any position of the exhaust pipeline 3100, as long as the foam in the exhaust pipeline 3100 can be reversely flushed back to the first barrel 3000. In addition, it should be noted that the reverse here refers to the direction relative to the gas or foam overflowing the exhaust pipeline 3100, that is, if the discharge direction of the gas is defined as from inside to outside, the reverse here is from outside to inside.
In the process of the foam being reversely flushed back to the first barrel 3000 by the water flowing out of the first water inlet pipe 4100, part of the foam can be dissipated by the impact of the reverse water flow, and part of the foam flowing back into the first barrel 3000 is blocked by the continuous backwashing water flow and cannot overflow into the exhaust pipeline 3100, and gradually dissipates in the first barrel 3000, and the remaining foam is discharged to the outside of the washing machine through the drainage pipeline along with the waste water in the first barrel 3000.
The technical solutions provided by the embodiments of the present disclosure may include the following beneficial effects. The water inlet system of the washing machine provided by the present disclosure is provided with the first water inlet pipe 4100, and the water outlet of the first water inlet pipe 4100 is communicated with the exhaust pipeline 3100. When part of the foam overflows from the first barrel 3000 to the exhaust pipeline 3100, in order to prevent the foam from continuing to overflow outside the washing machine, the water from the first water inlet pipe 4100 can enter the exhaust pipeline 3100. The foam can be reversed back to the first barrel 3000, and the foam can be re-dissolved in the reverse flushing and in the first barrel 3000. The undissolved foam will not overflow to the exhaust pipeline due to blocking by the reverse flushing water, and then be discharged from the drainage pipeline, which plays the role of dissolving the foam and avoiding polluting the indoor environment.
Any structure or method that can realize the introduction of the water from the first water inlet pipe 4100 into the first barrel 3000 and avoid overflowing from the exhaust pipeline 3100 as much as possible can be applied to the present disclosure. In some implementations, as shown in FIG. 3, a water guide structure 3110 is provided in the exhaust pipeline 3100 to partially guide the water discharged from the first water inlet pipe 4100 into the first barrel 3000. The water guide structure 3110 may be, for example, a guide slope. In some other implementations, the exhaust pipeline 3100 may be provided obliquely and the lower end may be located at the side of the first barrel 3000, which is also conducive to guiding the water discharged from the first water inlet pipe 4100 into the first barrel 3000. In some other implementations, the water guide manners of providing the water guide structure 3110 in the exhaust pipeline 3100, providing the exhaust pipeline 3100 obliquely, and locating the lower end at the side of the first barrel 3000 may be used in combination. In addition, the water outlet of the first water inlet pipe 4100 may be arranged toward the first barrel 3000, that is, the water is discharged directly from the first water inlet pipe 4100 toward the the first barrel 3000, which is also conducive to achieving the purpose of flushing the overflowed foam back to the first barrel 3000.
In some implementations, as shown in FIG. 1, the water inlet system of the washing machine further includes a second water inlet pipe 4200, the water outlet of the second water inlet pipe 4200 is communicated with the water inlet of the first barrel 3000, and the water inlet of the first water inlet pipe 4100 is communicated with the second water inlet pipe 4200. The second water inlet pipe 4200 is used to inject water into the first barrel 3000. The water inlet of the first water inlet pipe 4100 is communicated with the second water inlet pipe 4200, and the first water inlet pipe 4100 can be regarded as a branch pipeline led out from the second water inlet pipe 4200. That is, when water is injected into the first barrel 3000, part of the water in the second water inlet pipe 4200 can enter the first water inlet pipe 4100 at the same time. Compared with the method of leading a separate pipeline from the water inlet valve to the exhaust pipeline 3100, this method of introducing a branch water inlet pipeline has a simpler wiring structure, which is conducive to optimizing the internal space layout of the washing machine.
Further, a three-way valve 4300 may be provided on the second water inlet pipe 4200, and the water inlet of the first water inlet pipe 4100 is communicated with the three-way valve 4300. By providing the three-way valve 4300, the first water inlet pipe 4100 can be selectively opened and closed, that is, the three-way valve 4300 can be opened as needed. For example, when it is detected that no foam has overflowed into the exhaust pipeline 3100, the first water inlet pipe 4100 can be closed to save water.
The water inlet system of the washing machine in the present disclosure can be applied to a single-drum washing machine, and preferably can also be applied to a double-drum washing machine. Taking the washing machine as a double-drum washing machine as an example, the water inlet system of the washing machine provided in the present disclosure can also include a second barrel (not shown in the figure), and the barrel diameter of the first barrel 3000 is smaller than the barrel diameter of the second barrel. That is, the first barrel 3000 is a small barrel, and the second barrel is a large barrel. For the large barrel, since the barrel diameter is usually large and the volume is also large, most of the foam can be self-dissolved in the barrel or discharged from the drain pipe. As for the small barrel, due to the relatively small volume, the foam that can be self-dissolved is also limited, thereby increasing the risk of foam overflowing from the exhaust pipeline 3100. The water inlet system of the washing machine provided by the present disclosure can advantageously solve this problem of the small barrel.
As shown in FIG. 1, the exhaust pipeline 3100 may be arranged on a side portion of the first barrel 3000. The side portion here is different from the method of arranging the exhaust pipeline 3100 at the top or bottom of the barrel in the related art. Arranging the exhaust pipeline 3100 on the side portion of the first barrel 3000 can save the top or bottom space of the first barrel 3000, thereby optimizing the design height of the washing machine. Moreover, since the first barrel 3000 and the second barrel in the washing machine are usually arranged up and down, arranging the exhaust pipeline 3100 on the side portion is conducive to avoiding interference between the upper and lower barrels. However, considering that the volume of the first barrel 3000 is relatively small, arranging the exhaust pipeline 3100 on the side portion of the first barrel 3000, that is, the exhaust position being relatively low, which may aggravate the overflow of foam from the exhaust pipeline 3100. Therefore, the foam in the exhaust pipeline 3100 is reversely flushed back into the first barrel 3000 through the first water inlet pipe 4100, thereby optimizing the internal design space of the washing machine while avoiding the risk of foam overflowing from the exhaust pipeline 3100.
In the implemention where the washing machine is a double-drum washing machine, further, the water inlet system of the washing machine may also include a third water inlet pipe 4400, and the water outlet of the third water inlet pipe 4400 is communicated with the water inlet of the second barrel. That is, the first barrel 3000 and the second barrel are respectively configured with one water inlet pipe, so that the water inflow of the first barrel 3000 and the second barrel can be independently controlled.
As shown in FIG. 1, the water inlet system of the washing machine provided by the present disclosure may also include a water inlet box 4500, which may be regarded as an apparatus for distributing incoming water. Specifically, referring to FIG. 2 at the same time, the inlet of the water inlet box 4500 is communicated with the water inlet valve through a pipeline, and the water inlets of the second water inlet pipe 4200 and the third water inlet pipe 4400 are respectively communicated with the outlet of the water inlet box 4500. When working, the water inlet valve is opened, and water enters the water inlet box 4500 from the water inlet valve, and then is distributed to the second water inlet pipe 4200 and the third water inlet pipe 4400 by the water inlet box 4500. A part of the water entering the second water inlet pipe 4200 can further enter the first water inlet pipe 4100 by controlling the three-way valve 4300.
The water inlet box 4500 has the function of integrating the pipelines. Specifically, by integrating the originally independently arranged water pipes into the water inlet box 4500, the layout of the internal pipelines of the washing machine is further optimized. Compared with assembling multiple water pipes, the integrated water inlet box 4500 is conducive to saving the number of water pipes to be installed, optimizing the layout and improving the assembly efficiency of the whole washing machine.
The design of the water inlet box 4500 integrating multiple water pipes can be realized by setting multiple water paths inside the water inlet box 4500, for example, the water paths are formed by setting multiple ribs inside the water inlet box 4500 and reasonably designing the number and direction of the ribs. Specifically, the water inlet box 4500 is provided with a first water path 4510 communicated with the water inlet valve, a second water path 4520 communicated with the first barrel 3000, and a third water path 4530 communicated with the second barrel.
The water inlet box 4500 can be designed so that the water in the first water path 4510 directly enters the second water path 4520 and the third water path 4530, or the water inlet box 4500 can also be designed so that the water in the first water path 4510 first enters the dispensing box for accommodating the laundry detergent, and then the mixture of the laundry detergent and water enters the second water path 4520 and the third water path 4530 respectively. The latter method is suitable for washing machines with dispensing boxes.
In some implementations, continuing to refer to FIG. 2, the water inlet box 4500 is provided with a first water inlet interface 4511 and a first water outlet interface 4512 communicated with the first water path 4510, a second water inlet interface 4521 and a second water outlet interface 4522 communicated with the second water path 4520, and a third water inlet interface 4531 and a third water outlet interface 4532 communicated with the third water path 4530. Among them, the first water inlet interface 4511 is suitable for communicating with the water inlet valve, the first water outlet interface 4512 is suitable for communicating with the dispensing box for accommodating the laundry detergent, the second water inlet interface 4521 and the third water inlet interface 4531 are suitable for communicating with the dispensing box, the second water outlet interface 4522 is suitable for communicating with the first barrel 3000, and the third water outlet interface 4532 is suitable for communicating with the second barrel.
Cleaning materials such as laundry detergent are placed in the dispensing box. The water in the first water path 4510 is flushed into the dispensing box. Since the water inlet pipeline is a closed structure, under the action of water pressure, the laundry detergent mixed with water in the dispensing box is flushed into the second water path 4520 and the third water path 4530, and then enters the first barrel 3000 and the second barrel respectively.
The water outlet of the first water inlet pipe 4100 can be directly communicated with the exhaust pipeline 3100, or indirectly communicated with the exhaust pipeline 3100 through the drainage and ventilation box 3200. Specifically, as shown in FIGs. 1 and 4, the water inlet system of the washing machine of the present disclosure also includes a drainage and ventilation box 3200, which includes a shell 3210 and a ventilation cavity 3220 and a drainage cavity 3230 that are independent and separated from each other and arranged inside the shell 3210, and the exhaust pipeline 3100 and the water outlet of the first water inlet pipe 4100 are respectively communicated with the ventilation cavity 3220. The drainage and ventilation box 3200 in the present disclosure integrates drainage and ventilation, has a compact structural design, high integration, and effectively reduces the number of parts and costs. The foam overflows the ventilation cavity 3220 through the exhaust pipeline 3100, and the water outlet of the first water inlet pipe 4100 is communicated with the ventilation cavity 3220, so as to achieve the purpose of flushing the foam back into the first barrel 3000.
In some implementations, referring to FIG. 5, the shell 3210 may be provided with an air inlet 3211, a first water inlet pipe interface 3212 and an air outlet 3213 respectively communicated with the ventilation cavity 3220. The air outlet 3213 is communicated with the external environment, the air inlet 3211 is communicated with the exhaust pipeline 3100, the first water inlet pipe interface 3212 is communicated with the first water inlet pipe 4100, and the water discharged from the first water inlet pipe interface 3212 can be reversely flushed back into the first barrel 3000 through the air inlet 3211. The solid arrow in FIG. 5 is the exhaust direction of the first barrel 3000, that is, from the first barrel 3000 to the exhaust pipeline 3100 and then to the ventilation cavity 3220, and finally discharged from the air outlet 3213 to the room, and the dotted arrow is the flow direction of the water discharged from the first water inlet pipe 4100, that is, from the first water inlet pipe 4100 to the ventilation cavity 3220 through the first water inlet pipe interface 3212, and then back to the first barrel 3000 from the air inlet 3211.
The ventilation cavity 3220 may include a first ventilation chamber 3221 and a second ventilation chamber 3222 that are communicated with each other. The first ventilation chamber 3221 is communicated with the air outlet 3213, the second ventilation chamber 3222 is respectively communicated with the air inlet 3211 and the first water inlet pipe interface 3212, and the second ventilation chamber 3222 is formed by extending downward from the side portion of the first ventilation chamber 3221. Specifically, the first ventilation chamber 3221 and the second ventilation chamber 3222 are constructed in a bent shape, that is, the gas flows from bottom to top when exhausting, and the water flows from top to bottom when water enters. In this way, water can be prevented from overflowing from the air outlet 3213 into the room as much as possible, and more water is pushed back to the exhaust pipeline 3100 under the action of gravity.
In other implementations, as shown in FIG. 6, the shell 3210 may be provided with a first water inlet 3214, a second water inlet 3215 and a drain 3216, and the drainage cavity 3230 is provided with a first drainage channel 3231 and a second drainage channel 3232 that are communicated with each other; the upstream end of the first drainage channel 3231 is communicated with the first water inlet 3214, and the downstream end of the first drainage channel 3231 is communicated with the drain 3216; the upstream end of the second drainage channel 3232 is communicated with the second water inlet 3215, and the downstream end of the second drainage channel 3232 is communicated with the downstream end of the first drainage channel 3231 and is communicated with the drain 3216.
In this emplementation, the first drainage channel 3231 includes a plurality of channel sections that are communicated with each other to be set to a meandering channel shape to meet the drainage requirements. However, the present disclosure does not limit the specific shape of the first drainage channel 3231. Optionally, the first drainage channel 3231 may include a first channel section 32311 and a second channel section 32312; the upstream end of the first channel section 32311 is communicated with the first water inlet 3214, the downstream end of the first channel section 32311 is communicated with the upstream end of the second channel section 32312, and the downstream end of the second channel section 32312 is communicated with the drain 3216; the downstream end of the second drainage channel 3232 is communicated with the downstream end of the second channel section 32312 and is communicated with the drain 3216.
That is, in this implementation, the first channel section 32311 and the second channel section 32312 jointly define a U-shaped channel shape. When water enters the first drainage channel 3231 from the first water inlet 3214, it first passes through the first channel section 32311 and then flows to the second channel section 32312, and then is discharged through the drain 3216. When water enters the second drainage channel 3232 from the second water inlet 3215, the water at the downstream end of the second drainage channel 3232 can then merge with the water at the downstream of the second channel section 32312, and then the water is discharged through the drain 3216.
According to the second aspect of the embodiments of the present disclosure, a washing machine is also provided, including the water inlet system of the washing machine in any of the above embodiments, and having all its beneficial effects, which will not be repeated here. Optionally, the washing machine may be a double-drum washing machine, in which the first barrel 3000 may be a small barrel.

For example, it may be a fixed connection, a detachable connection, or an integral one, it may be a mechanical connection, an electrical connection, or communication with each other, it may be a direct connection, or an indirect connection through an intermediate medium, and it may be the internal communication of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For the person skilled in the art, the specific meanings of the above terms in the present disclosure can be understood according to the specific circumstances.
In addition, the word "on" used in relation to a component, element or material layer formed "on" or located "on" a surface can be used in the present disclosure to indicate that the component, element or material layer is "indirectly" positioned (for example, placed, formed, deposited, etc.) on the surface so that one or more additional parts, components or layers are arranged between the surface and the component, element or material layer. However, the word "on" used in relation to a component, element or material layer formed "on" or located "on" a surface may also optionally have a specific meaning: the component, element or material layer is "directly" positioned (e.g., placed, formed, deposited, etc.) on the surface, such as in direct contact with the surface.
Although terms such as "first," "second" and "third" may be used herein to describe various parts, components, regions, layers or sections, these parts, components, regions, layers or sections are not limited to these terms. On the contrary, these terms are only used to distinguish one part, component, region, layer or section from another part, component, region, layer or section. Therefore, without departing from the teachings of the examples described herein, the first part, component, region, layer or section mentioned in the examples described herein may also be referred to as the second part, component, region, layer or section. In addition, the terms "first" and "second" are used only for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In the description herein, "multiple/a plurality of" means at least two, such as two, three, etc., unless otherwise clearly and specifically defined.
It should be understood that spatially relative terms such as "above," "upper," "below" and "lower" are used herein to describe the relationship between one element and another element shown in the figure. In addition to the orientation depicted in the drawings, such spatially relative terms are also intended to include different orientations of the apparatus in use or operation. For example, if the apparatus in the drawings is turned over, the element described as being "above" or "upper" relative to another element will be "below" or "lower" relative to the another element. Therefore, depending on the spatial orientation of the apparatus, the term "above" includes both upper and lower orientations. The apparatus may have other orientations (e.g., rotated 90 degrees or in other orientations), and the spatially relative terms used herein should be interpreted accordingly.
In addition, the word "exemplary" is used herein to indicate serving as an example, instance, or illustration. Any aspect or design described as "exemplary" in the present disclosure is not necessarily understood to be advantageous compared to other aspects or designs. Instead, the use of the word exemplary is intended to present concepts in a particular manner. As used herein, the term "or" is intended to mean an inclusive "or" rather than an exclusive "or". That is, unless otherwise specified or clear from the context, "X applies A or B" is intended to mean any of the natural inclusive permutations. That is, if X applies A; X applies B; or X applies both A and B, then "X applies A or B" satisfies any of the foregoing instances. In addition, unless otherwise specified or clear from the context to point to a singular form, the articles "a" and "an" as used in the present application and the appended claims are generally understood to mean "one or more".
Likewise, although the present disclosure has been shown and described with respect to one or more implementations, equivalent variations and modifications will occur to those skilled in the art after reading and understanding this specification and the accompanying drawings. The present disclosure includes all such modifications and variations and is limited only by the scope of the claims. With particular regard to the various functions performed by the components (e.g., elements, resources, etc.) described above, unless otherwise noted, the terms used to describe such components are intended to correspond to any component (functionally equivalent) that performs the specific functions of the described components, even if not structurally equivalent to the disclosed structures. In addition, although specific features of the present disclosure may have been disclosed with respect to only one of several implementations, such features may be combined with one or more other features of other implementations as may be desired and advantageous for any given or particular application. In addition, with respect to the use of "including," "possessing," "having," "owning," or variations thereof in the specific embodiments or claims, such terms are intended to be inclusive in a manner similar to the term "containing".
Other implementations of the present disclosure will be readily apparent to those skilled in the art after considering the specification and practicing the contents disclosed herein. This application is intended to cover any variations, uses, or adaptations of the present disclosure that follow the general principles of the present disclosure and include common knowledge or customary technical means in the art that are not disclosed in the present disclosure. The specification and embodiments are to be regarded as exemplary only, and the true scope and spirit of the present disclosure are indicated by the appended claims.
