Description

[0001] This application claims priority to Chinese Patent Application No. 202421885711.7, filed on August 5, 2024, entitled "Clothing Processing Equipment", the entire contents of which are incorporated herein by reference. Technical Field

[0002] This utility model relates to the field of household appliance technology, and in particular to a clothing processing device. Background Technology

[0003] Clothing handling equipment in related technologies, such as drum washing machines, typically have a closed washing chamber due to their unique structure. Therefore, to ensure smooth water supply, an exhaust pipe is usually installed to connect the washing chamber to the external environment, releasing the gas pressure within the closed washing chamber during the water supply phase. However, this setup can lead to a problem during the washing process where a large amount of foam overflows through the exhaust pipe into the external environment, contaminating the surrounding area of ​​the clothing handling equipment. Utility Model Content

[0004] The description of the utility model introduces a series of simplified concepts, which will be further explained in detail in the detailed description section. This part of the utility model is not intended to limit the key features and essential technical features of the claimed technical solution, nor is it intended to determine the scope of protection of the claimed technical solution.

[0005] In a first aspect, this utility model provides a garment processing device, comprising: a drum body having a receiving cavity for containing liquid; and an exhaust pipe disposed outside the drum body, with a first end of the exhaust pipe connected to the receiving cavity and a second end of the exhaust pipe connected to the outside of the garment processing device; wherein the first end of the exhaust pipe is located outside the washing water level range of the drum body, and the washing water level range of the drum body is from the lowest design water level of the drum body to the highest design water level of the drum body.

[0006] Furthermore, the first end of the exhaust pipe includes a first air inlet end, which is higher than the highest design water level of the cylinder; wherein the first air inlet end is connected to the top or side of the cylinder.

[0007] Furthermore, the first end of the exhaust pipe includes a second air inlet end, which is lower than the lowest design water level of the cylinder, and the second end of the exhaust pipe is located above the second air inlet end; wherein the second air inlet end is connected to the bottom or side of the cylinder.

[0008] Furthermore, the first end of the exhaust pipe includes a first air inlet end, which is located above the highest water level of the cylinder and is connected to the top or side of the cylinder; the first end of the exhaust pipe also includes a second air inlet end, which is located below the lowest water level of the cylinder and is connected to the bottom or side of the cylinder; wherein, the second end of the exhaust pipe is located between the first air inlet end and the second air inlet end.

[0009] Furthermore, the vertical distance between the second end of the exhaust pipe and the first intake end is less than the vertical distance between the second end of the exhaust pipe and the second intake end.

[0010] Furthermore, the exhaust pipe includes a first pipe connected to a first intake end and a second pipe connected to a second intake end, wherein the cross-sectional area of ​​the second pipe perpendicular to the fluid flow direction is greater than the cross-sectional area of ​​the first pipe perpendicular to the fluid flow direction.

[0011] Furthermore, a wall-breaking structure is provided on the inner wall between the first intake end and the second end of the exhaust pipe. The wall-breaking structure includes at least one of a tapering structure, a bending structure, and a rib. The tapering structure is configured such that the cross-sectional area of ​​the exhaust pipe gradually decreases from the first intake end to the second end of the exhaust pipe.

[0012] Furthermore, the cylinder includes an outer cylinder and an inner cylinder rotatably disposed inside the outer cylinder, with the first air inlet end communicating with the top wall of the outer cylinder.

[0013] Furthermore, the cylinder includes an outer cylinder and an inner cylinder rotatably disposed inside the outer cylinder, and the second air inlet is connected to the side wall of the outer cylinder.

[0014] Furthermore, the garment processing device also includes: a housing disposed outside the cylinder; a drain pipe disposed between the cylinder and the housing, the drain pipe connecting the receiving cavity and the external environment; wherein, the second end of the exhaust pipe is connected to the drain pipe; or the second end of the exhaust pipe is connected to the through hole of the housing, and the garment processing device also includes a transition pipe located outside the housing connecting the through hole and the drain pipe.

[0015] Furthermore, the garment processing equipment also includes a water collection device, which is located outside the drum body, and the second end of the exhaust pipe is connected to the water collection device.

[0016] Furthermore, the garment processing equipment also includes: a housing disposed outside the cylinder; electrical components disposed between the housing and the cylinder; and a connecting pipe disposed between the housing and the cylinder, with a first end of the connecting pipe connected to a second end of an exhaust pipe, and the second end of the connecting pipe extending between the housing and the cylinder and disposed away from the electrical components.

[0017] Furthermore, the exhaust pipe is also equipped with a connecting joint installed at the second end of the exhaust pipe.

[0018] The garment processing device provided by this utility model includes a drum and an exhaust pipe. The drum has a receiving cavity for containing liquid. By providing an exhaust pipe connected to the receiving cavity outside the drum, during water intake, the airflow inside the receiving cavity is discharged to the outside of the receiving cavity through the inlet, outlet, and outlet of the exhaust pipe, releasing the air pressure inside the receiving cavity and ensuring that water can smoothly and quickly enter the receiving cavity. By placing the inlet of the exhaust pipe outside the designed washing water level range of the drum, the possibility of foam flowing into the exhaust pipe through the inlet during washing is reduced. This reduces the problem of foam overflowing from the receiving cavity into the external environment through the outlet of the exhaust pipe and contaminating the surrounding environment of the garment processing device, greatly improving the cleanliness of the surrounding environment and enhancing the user experience.

Detailed Implementation

[0035] The following description provides numerous specific details to offer a more thorough understanding of the technical solutions provided by this invention. However, it will be apparent to those skilled in the art that the technical solutions provided by this invention can be implemented without one or more of these details.

[0036] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to the present invention. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of the stated features, integrals, steps, operations, elements, and / or components, but do not exclude the presence or addition of one or more other features, integrals, steps, operations, elements, components, and / or combinations thereof.

[0037] Exemplary embodiments according to the present invention will now be described in more detail with reference to the accompanying drawings. However, these exemplary embodiments may be implemented in many different forms and should not be construed as being limited to the embodiments set forth herein. It should be understood that these embodiments are provided so that the disclosure of the present invention is thorough and complete, and that the concept of these exemplary embodiments is fully conveyed to those skilled in the art.

[0038] like Figures 1 to 11 As shown, an embodiment of this utility model provides a clothing processing device 100. The clothing processing device 100 is typically a drum washing machine, a washer-dryer combo, etc.

[0039] During the water intake or washing process of the garment processing equipment 100 (such as a drum washing machine), the drum 110 is a closed system, requiring the exhaust pipe 120 to balance the air pressure inside and outside the drum 110. However, if the detergent mixes with water quickly, too much detergent is added, or the mixture agitates or rubs against the clothes, a large amount of foam may be generated in the drum 110. During the exhaust process through the exhaust pipe 120, some of the foam and / or the mixture is carried out, resulting in overflow. Overflow can contaminate the environment around the garment processing equipment 100, reducing the user experience. Furthermore, liquid or foam splashes may affect the user's electrical safety, posing a certain safety hazard.

[0040] Therefore, as Figure 1 As shown, in this embodiment, the exhaust pipe 120 is located at the top of the drum 110 to reduce the probability of foam overflowing from the drum 110. However, in some other possible embodiments of this disclosure, the exhaust port 114 can also be located on the side of the drum 110, as long as the position of the exhaust port 114 is higher than the highest washing water level of the drum 110. This expands the arrangement range of the exhaust port 114 and reduces design requirements.

[0041] In addition, the intake diameter of the exhaust pipe 120 can be set to be larger than the exhaust diameter to defoam when foam passes through the exhaust pipe 120. For example, the diameter of the exhaust pipe 120 can be set to gradually decrease (constriction) from the intake port to the exhaust port, either entirely or partially.

[0042] Among them, although Figure 1 The exhaust pipe 120 shown is a round pipe or a near-round pipe, but those skilled in the art will understand that the shape of the exhaust pipe 120 can also be square, triangular, or any other arbitrary shape. This disclosure does not limit the shape of the exhaust pipe 120. The opening area of ​​the air inlet is larger than the opening area to the air outlet, so that the exhaust pipe 120 has a tapered or partially tapered structure, which can realize the defoaming and backflow of foam.

[0043] In addition, such as Figure 1As shown, it is understood that the length of the exhaust pipe 120 can be extended without affecting the exhaust efficiency, and / or the exhaust pipe 120 can be partially or entirely made into a corrugated pipe, or have flexible or rigid bends, protrusions, ribs, etc., so as to further defoam the foam flowing into the exhaust pipe 120 and prolong the time for foam defoaming and the time for foam to flow back to the cylinder 110 after defoaming, thereby reducing the probability that the foam is carried out of the exhaust pipe 120.

[0044] Among them, the clothing processing equipment 100 can be a drum washing machine, a washer-dryer combo, etc. The clothing washing capacity of the clothing processing equipment 100 can be, for example, 3-5 kg ​​for small models, 6-8 kg for medium models, 9 kg and above for large models, or less than 3 kg for mini models.

[0045] The following will be by Figure 2 Another embodiment of the garment processing apparatus 100 described herein will be explained. Figure 2 This is a schematic diagram of the structure of a garment processing device 100 according to another embodiment of this disclosure. Figure 2 As shown, the garment processing device 100 includes a drum 110 and a drain pipe 160. The drum 110 contains a receiving cavity (…). Figure 2 (Not shown) A vent 114 extending into the receiving cavity is provided on the outer periphery of the drum 110. The vent 114 is located below the lowest washing water level of the drum 110 and connects to a vent pipe 120. The vent pipe 120 is located outside the drum 110, with its first end connected to the receiving cavity and its second end connected to the outside of the clothes handling device 100. The first end of the vent pipe is outside the washing water level range of the drum 110, which ranges from the lowest designed water level to the highest designed water level of the drum 110. Specifically, the vent pipe 120 includes an inlet end and an outlet end. The inlet end connects to the vent 114 of the drum 110, and the outlet end is positioned above the inlet end and connects to the outside of the clothes handling device 100. The first end of the vent pipe 120 has an inlet connected to the receiving cavity, and the second end has an outlet.

[0046] During the water intake or washing process of the garment processing equipment 100 (such as a drum washing machine), the drum 110 is a closed system, requiring the exhaust pipe 120 to balance the air pressure inside and outside the drum 110. However, if too much detergent is added, or if the detergent mixes with water quickly, or if the mixture agitates or rubs against the clothes, a large amount of foam may be generated in the drum 110. During the exhaust process through the exhaust pipe 120, some of the foam and / or the mixture may be carried out, resulting in overflow. Overflow can contaminate the environment around the garment processing equipment 100, reducing the user experience. Furthermore, liquid or foam splashes may affect the user's electrical safety, posing a certain safety hazard.

[0047] like Figure 2 As shown, in this embodiment, the first end of the exhaust pipe 120 is set higher than the highest washing water level of the drum 110, or even nearly flush with, at the same height as, or slightly higher than the height of the drum 110. This means that unless the washing water level exceeds the highest washing water level of the drum 110, the washing water will not overflow the exhaust pipe 120. Furthermore, the exhaust port 114 is set at a position below the lowest washing water level of the drum 110 to seal the foam with washing water and prevent the foam from being washed out of the drum 110.

[0048] Since the actual washing water level in the receiving cavity during the water intake or washing process will not be higher than the highest washing water level of the drum 110, nor lower than the lowest washing water level of the drum 110, the actual washing water level in the receiving cavity during the washing process is lower than the air outlet of the exhaust pipe 120 and higher than the air inlet of the exhaust pipe 120. In other words, the air inlet of the exhaust pipe 120 is always covered by the liquid surface, and most of the foam floats on the liquid surface inside the drum 110, so very little foam, or almost no foam, will flow into the exhaust pipe 120 through the air inlet.

[0049] Understandably, during the water intake or drainage process of the garment processing device 100, the actual washing water level in the receiving cavity may gradually rise above the air intake end of the exhaust pipe 120, or gradually decrease below the air intake end of the exhaust pipe 120. However, since water intake occurs before the washing process, before overflowing the air intake end of the exhaust pipe 120, the exhaust of the garment processing device 100 directly passes through the un-overflowed portion of the air intake end. Drainage is relatively fast and occurs after the washing process, and most of the foam will defoam during the washing process due to sufficient contact with the clothes. Therefore, there is little or almost no foam on the liquid surface during the drainage operation. During drainage, some of the foam on the liquid surface will remain on the clothes, and some will be discharged with the liquid. At this time, the internal air pressure of the drum 110 is not enough to cause overflow. Therefore, only a very small amount of foam will remain on the inner wall or bottom of the exhaust pipe 120, and will not overflow through the air outlet end of the exhaust pipe 120. Therefore, almost no foam will overflow through the vent pipe 120 during the drainage operation, thereby further reducing the possibility of foam in the cylinder 110 overflowing from the vent pipe 120 into the clothing treatment device 100.

[0050] In addition, such as Figure 3 , Figure 10 and Figure 11As shown, the clothing processing device 100 provided in this embodiment of the present invention includes a cylinder 110 and an exhaust pipe 120. The receiving cavity 111 of the cylinder 110 is used to contain liquid for washing the clothes inside the receiving cavity 111. By providing an exhaust pipe 120 outside the cylinder 110, the inlet 121 at the first end of the exhaust pipe 120 is connected to the receiving cavity 111, so that when water is introduced into the receiving cavity 111, the airflow in the receiving cavity 111 is discharged to the outside of the receiving cavity 111 through the inlet 121 of the exhaust pipe 120, the exhaust pipe 120, and the outlet 122 at the second end of the exhaust pipe 120, releasing the air pressure inside the receiving cavity 111. Thus, water can smoothly and quickly enter the receiving cavity 111, ensuring the smoothness and speed of the water introduction operation of the receiving cavity 111.

[0051] For the garment processing equipment 100, a minimum design water level for the drum 110 is typically set during the design process, such as... Figure 9 As shown by line L, during the washing process, the actual water level in the receiving cavity 111 is higher than or equal to the minimum design water level of the drum 110 to ensure sufficient liquid volume in the receiving cavity 111 and a good washing effect. Meanwhile, the maximum design water level of the drum 110 is typically designed, such as... Figure 7 As shown by line H, during the washing process, the actual water level in the receiving cavity 111 is lower than or equal to the highest designed water level of the drum 110 to avoid overflow due to excessive water level in the receiving cavity 111. In other words, during the design process, the range of designed washing water levels for the drum 110 should not be higher than the highest designed water level of the drum 110, nor lower than the lowest designed water level of the drum 110. This ensures that the actual water level in the receiving cavity 111 is within the range of the designed washing water levels of the drum 110 during the washing process, thus ensuring good washing performance and reducing the occurrence of overflow. Figure 7 and Figure 9 The direction indicated by the arrow Z in the image can be understood as the vertical direction.

[0052] Under normal circumstances, the garment processing equipment 100 is equipped with a water level sensor to detect the actual washing water level in the receiving cavity 111, so as to ensure that the actual washing water level in the receiving cavity 111 is within the range of the designed washing water level of the drum 110. That is, it can ensure that the actual water level in the receiving cavity 111 should not be higher than the highest designed water level of the drum 110, and not lower than the lowest designed water level of the drum 110.

[0053] Since the actual washing water level in the receiving cavity 111 during the washing process is not higher than the highest design water level of the drum 110 and not lower than the lowest design water level of the drum 110, in this embodiment, by setting the inlet 121 of the exhaust pipe 120 outside the design washing water level range of the drum 110, that is, the inlet 121 of the exhaust pipe 120 is higher than the highest design water level of the drum 110 or lower than the lowest design water level of the drum 110, the possibility of foam flowing into the exhaust pipe 120 through the inlet 121 during the washing process can be reduced. In turn, the problem of foam in the receiving cavity 111 overflowing into the external environment through the outlet 122 of the exhaust pipe 120 and polluting the environment around the clothing processing equipment 100 can be reduced, which greatly improves the cleanliness of the environment around the clothing processing equipment 100 and enhances the user experience.

[0054] Specifically, the inlet 121 of the exhaust pipe 120 is set higher than the highest designed water level of the drum 110. Since the actual washing water level in the receiving cavity 111 during the washing process is neither higher than the highest designed water level of the drum 110 nor lower than the lowest designed water level of the drum 110, meaning the actual washing water level in the receiving cavity 111 during the washing process is below the inlet 121 of the exhaust pipe 120, and the laundry handling equipment 100 rarely uses the highest designed water level for washing operations, in other words, when the inlet 121 of the exhaust pipe 120 is higher than... When the drum 110 reaches its highest design water level, in practical applications, the actual washing water level in the receiving cavity 111 is located below and at a certain distance from the inlet 121 of the exhaust pipe 120. This reduces the likelihood of foam in the receiving cavity 111 flowing into the exhaust pipe 120 via the inlet 121, which is located above the highest design water level of the drum 110. Consequently, it reduces the possibility of foam overflowing into the external environment via the outlet 122 of the exhaust pipe 120, significantly improving the cleanliness of the surrounding environment of the garment processing equipment 100. It is understandable that the possibility of foam flowing into the exhaust pipe 120 via the inlet 121 can be reduced by rationally designing the distance between the inlet 121 of the exhaust pipe 120 and the highest design water level of the drum 110.

[0055] Specifically, the inlet 121 of the exhaust pipe 120 is set below the lowest design water level of the drum 110. Since the actual washing water level in the receiving cavity 111 during the washing process is neither higher than the highest design water level of the drum 110 nor lower than the lowest design water level, the actual washing water level in the receiving cavity 111 during the washing process is located above the inlet 121 of the exhaust pipe 120, and the inlet 121 of the exhaust pipe 120 is always covered by liquid. Since foam usually floats on the liquid surface during the washing process, very little or no foam flows into the exhaust pipe 120 through the inlet 121, which is located below the lowest design water level of the drum 110. Therefore, the possibility of foam in the receiving cavity 111 overflowing into the external environment through the outlet 122 of the exhaust pipe 120 can be reduced, greatly improving the cleanliness of the environment surrounding the garment processing equipment 100. Understandably, during the drainage operation of the receiving cavity 111, the actual washing water level in the receiving cavity 111 will pass through the inlet 121 of the exhaust pipe 120. However, since the drainage operation usually takes place after the washing process, and most of the foam has fully contacted the clothes and broken the walls during the washing process, there is little or almost no foam on the liquid surface during the drainage operation. During the drainage process, some of the little foam on the liquid surface will remain on the clothes, some will be discharged with the liquid, and only a very small portion will flow into the exhaust pipe 120 through the inlet 121. This very small amount of foam will remain inside the exhaust pipe 120 and will not overflow through the outlet 122. Therefore, almost no foam will overflow through the exhaust pipe 120 during the drainage operation. This further reduces the possibility of foam in the receiving cavity 111 overflowing into the external environment through the outlet 122 of the exhaust pipe 120, greatly improving the cleanliness of the environment surrounding the clothing processing equipment 100. Figure 1 , Figure 5 and Figure 6 As shown, in some possible embodiments provided by this utility model, the first end of the exhaust pipe 120 includes a first air inlet end, which is higher than the highest design water level of the cylinder 110, and the first air inlet end communicates with the top or side of the cylinder 110. Specifically, the inlet 121 includes a first inlet 1211 located at the first air inlet end, which is located above the highest design water level of the cylinder 110.

[0056] In this embodiment, the exhaust pipe 120 may be provided with a first inlet 1211 located above the highest designed water level of the drum 110. The exhaust pipe 120 is connected to the drum 110 through the first inlet 1211 located above the highest designed water level of the drum 110. In this way, during the water intake operation of the clothing processing equipment 100, the gas in the receiving cavity 111 is discharged through the first inlet 1211 and then through the exhaust pipe 120, ensuring the smoothness and speed of the water intake operation. At the same time, since the first inlet 1211 is located above the highest designed water level of the drum 110, in actual scenarios, the actual washing water level in the receiving cavity 111 is located below the first inlet 1211 of the exhaust pipe 120. Therefore, the possibility of foam in the receiving cavity 111 flowing into the exhaust pipe 120 through the first inlet 1211 located above the highest designed water level of the drum 110 can be reduced, thereby reducing the possibility of foam overflowing into the external environment through the outlet 122 of the exhaust pipe 120, greatly improving the cleanliness of the surrounding environment of the clothing processing equipment 100.

[0057] Furthermore, the possibility of foam flowing into the exhaust pipe 120 through the first inlet 1211 can be further reduced by rationally designing the distance between the first inlet 1211 of the exhaust pipe 120 and the highest design water level of the drum 110. It is understood that the highest design water level of the drum 110 of a drum washing machine is generally located in the middle or slightly above the middle position. Therefore, the distance between the first inlet 1211 and the highest design water level of the drum 110 can be set within the range of 10cm to 30cm to further reduce the possibility of foam flowing into the exhaust pipe 120 through the inlet 121. Since the liquid surface of the garment handling equipment 100 will slosh and become uneven during the washing process due to the movement of the drum 110 and the impact of the clothes, and foam often resides on the liquid surface during washing, setting the first inlet 1211 10cm to 30cm above the highest design water level can reduce the possibility of foam entering the exhaust pipe 120 through the first inlet 1211 due to the sloshing of the liquid surface. Specifically, the distance between the first inlet 1211 and the highest design water level of the cylinder 110 can be 10cm, 15cm, 20cm, 25cm, 30cm, or other values.

[0058] Understandably, in this example, the outlet 122 of the exhaust pipe 120 can be located above, below, or flush with the first inlet 1211.

[0059] like Figure 2 , Figure 8 , Figure 9As shown, in some possible embodiments provided by this utility model, the first end of the exhaust pipe 120 includes a second air inlet end, which is lower than the lowest design water level of the cylinder 110, and the second end of the exhaust pipe 120 is located above the second air inlet end. Specifically, the inlet 121 includes a second inlet 1212 located at the second air inlet end, which is located below the lowest design water level of the cylinder 110.

[0060] In this embodiment, the exhaust pipe 120 may be provided with a second inlet 1212 located below the lowest design water level of the drum 110. The exhaust pipe 120 communicates with the drum 110 through the second inlet 1212 located below the lowest design water level of the drum 110. In this way, during the washing process, the actual washing water level in the receiving cavity 111 is located above the inlet 121 of the exhaust pipe 120, and the inlet 121 of the exhaust pipe 120 is always covered by liquid. Therefore, very little or almost no foam flows into the exhaust pipe 120 through the inlet 121 located below the lowest design water level of the drum 110. Meanwhile, since the drainage operation usually takes place after the washing process, and most of the foam breaks down due to full contact with the clothes during the washing process, there is little or no foam on the liquid surface during the drainage operation. During drainage, some of the little foam on the liquid surface remains on the clothes, some is discharged with the liquid, and only a very small portion flows into the exhaust pipe 120 through the second inlet 1212. This very small amount of foam remains inside the exhaust pipe 120 and does not overflow through the outlet 122. Therefore, almost no foam overflows through the exhaust pipe 120 during the drainage operation. As a result, the possibility of foam in the receiving cavity 111 overflowing into the external environment through the outlet 122 of the exhaust pipe 120 can be further reduced, greatly improving the cleanliness of the environment surrounding the clothing processing equipment 100.

[0061] It is understandable that, such as Figure 2 and Figure 9 As shown, in this example, the outlet 122 of the exhaust pipe 120 can be located above the second inlet 1212. Thus, when a very small amount of foam flows into the exhaust pipe 120 through the second inlet 1212 during drainage, since the outlet 122 of the exhaust pipe 120 is located above the second inlet 1212, this small amount of foam will remain inside the exhaust pipe 120 and will not overflow through the outlet 122. This further reduces the possibility of foam in the receiving cavity 111 overflowing into the external environment through the outlet 122 of the exhaust pipe 120, greatly improving the cleanliness of the surrounding environment of the clothing processing equipment 100.

[0062] like Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8and Figure 9 As shown, in some possible embodiments provided by this utility model, the first end of the exhaust pipe 120 includes a first air inlet end, which is located above the highest water level of the cylinder 110 and is connected to the top or side of the cylinder 110; the first end of the exhaust pipe 120 includes a second air inlet end, which is located below the lowest water level of the cylinder 110 and is connected to the bottom or side of the cylinder 110; wherein, the second end of the exhaust pipe 120 is located between the first air inlet end and the second air inlet end.

[0063] Specifically, the first inlet 1211 at the first air inlet end is located above the highest water level of the cylinder 110, and the second inlet 1212 at the second air inlet end is located below the lowest water level of the cylinder 110.

[0064] In this embodiment, the exhaust pipe 120 has two inlets: a first inlet 1211 located above the highest design water level of the cylinder 110, and a second inlet 1212 located below the lowest design water level of the cylinder 110. The exhaust pipe 120 is simultaneously connected to the cylinder 110 via both inlets 1211 and 1212. Compared to having only one inlet connected to the cylinder 110, this arrangement increases the exhaust volume, thereby further improving the smoothness and speed of the water intake operation of the garment processing equipment 100. However, this arrangement results in a higher cost for the exhaust pipe 120 and a more complex design for the cylinder 110. Therefore, the number of inlets 121 of the exhaust pipe 120 can be rationally designed based on the speed requirements of the water intake operation of the garment processing equipment 100, manufacturing costs, etc.

[0065] Meanwhile, in this embodiment, the exhaust pipe 120 is connected to the drum 110 through a first inlet 1211 located above the highest design water level of the drum 110, and also through a second inlet 1212 located below the lowest design water level of the drum 110. Since the first inlet 1211 is located above the highest design water level of the drum 110, in actual scenarios, the actual washing water level in the receiving cavity 111 is located below the first inlet 1211 of the exhaust pipe 120. This reduces the possibility that foam in the receiving cavity 111 may flow into the exhaust pipe 120 through the first inlet 1211 located above the highest design water level of the drum 110, thereby reducing the possibility that foam may overflow into the external environment through the outlet 122 of the exhaust pipe 120, and greatly improving the cleanliness of the surrounding environment of the clothing processing equipment 100. Since the second inlet 1212 is located below the lowest design water level of the drum 110, the inlet 121 of the exhaust pipe 120 is always covered by liquid during the washing process. Therefore, very little or no foam flows into the exhaust pipe 120 through the inlet 121 located below the lowest design water level of the drum 110, and almost no foam overflows through the exhaust pipe 120 during the drainage operation. As a result, the possibility of foam in the receiving cavity 111 overflowing into the external environment through the outlet 122 of the exhaust pipe 120 can be further reduced, which greatly improves the cleanliness of the surrounding environment of the garment processing equipment 100.

[0066] In this embodiment, the outlet 122 is located between the first inlet 1211 and the second inlet 1212. This ensures that the airflow passes through the first inlet 1211 and the second inlet 1212 and is smoothly discharged from the exhaust pipe 120 through the outlet 122. At the same time, the outlet 122 of the exhaust pipe 120 can be located above the second inlet 1212. When a very small amount of foam flows into the exhaust pipe 120 through the second inlet 1212 during the drainage process, this small amount of foam will remain inside the exhaust pipe 120 and will not overflow through the outlet 122. This further reduces the possibility of foam in the receiving cavity 111 overflowing into the external environment through the outlet 122 of the exhaust pipe 120, greatly improving the cleanliness of the surrounding environment of the clothing processing equipment 100. At the same time, this configuration can reduce the overall volume of the exhaust pipe 120, save the material used for the exhaust pipe 120, reduce the space occupied by the exhaust pipe 120 on the external space of the cylinder 110 of the clothing processing equipment 100, so that there is enough space outside the cylinder 110 to arrange other components. It also helps to reduce manufacturing costs and is suitable for widespread application.

[0067] In the above embodiment, the vertical distance between the second end of the exhaust pipe 120 and the first air inlet is less than the vertical distance between the second end of the exhaust pipe 120 and the second air inlet. Specifically, the vertical distance between the outlet 122 at the second end and the first inlet 1211 at the first air inlet is less than the vertical distance between the outlet 122 and the second inlet 1212 at the second air inlet. That is, the outlet 122 is located close to the first inlet 1211 and far from the second inlet 1212. This results in a larger vertical distance between the outlet 122 and the second inlet 1212, and a larger height difference between them. This increases the likelihood of foam flowing into the exhaust pipe 120 through the second inlet 1212 overflowing through the outlet 122, and further reduces the likelihood of foam in the receiving cavity 111 overflowing into the external environment through the outlet 122 of the exhaust pipe 120, greatly improving the cleanliness of the surrounding environment of the clothing processing equipment 100.

[0068] like Figure 3 , Figure 4 , Figure 5 , Figure 10 and Figure 11 As shown, in some possible embodiments provided by this utility model, the exhaust pipe 120 includes a first pipe 123 connected to a first air intake end and a second pipe 124 connected to a second air intake end. The cross-sectional area of ​​the second pipe 124 perpendicular to the fluid flow direction is larger than the cross-sectional area of ​​the first pipe 123 perpendicular to the fluid flow direction. Specifically, the exhaust pipe 120 includes a first pipe 123 connected to a first inlet 1211 and a second pipe 124 connected to a second inlet 1212. The cross-sectional area of ​​the second pipe 124 perpendicular to the fluid flow direction is larger than the cross-sectional area of ​​the first pipe 123 perpendicular to the fluid flow direction; that is, the second pipe 124 is thicker than the first pipe 123.

[0069] Since the second inlet 1212 is located below the lowest design water level of the cylinder 110, and the first inlet 1211 is located above the highest design water level of the cylinder 110, the probability of foam flowing into the exhaust pipe 120 through the second inlet 1212 is less than the probability of foam flowing into the exhaust pipe 120 through the first inlet 1211. Therefore, the second pipe 124, which is connected to the second inlet 1212 where the probability of foam entering is less, is designed to be a thicker pipe, and the first pipe 123, which is connected to the first inlet 1211 where the probability of foam entering is greater, is designed to be a thinner pipe. That is, the cross-sectional area of ​​the second pipe 124 perpendicular to the fluid flow direction is greater than the cross-sectional area of ​​the first pipe 123 perpendicular to the fluid flow direction. In this way, the smoothness and speed of exhaust of the exhaust pipe 120 can be improved without increasing the probability of foam flowing into the exhaust pipe 120, so as to ensure the smoothness and speed of water intake operation.

[0070] Specifically, during the water intake operation, most of the gas in the containment cavity 111 can be smoothly discharged through the second inlet 1212 via the second pipe 124 with a larger cross-sectional area and the outlet 122, while a small portion of the gas in the containment cavity 111 can be smoothly discharged through the first inlet 1211 via the first pipe 123 with a smaller cross-sectional area and the outlet 122, so as to ensure the smoothness and speed of the exhaust of the containment cavity 111 through the exhaust pipe 120, and thus ensure the smoothness and speed of the water intake operation.

[0071] like Figure 10 and Figure 11 As shown, in some possible embodiments provided by this utility model, the exhaust pipe 120 is provided with a wall-breaking structure on the inner wall between the first air intake end and the second end of the exhaust pipe. The wall-breaking structure includes at least one of a tapering structure, a bending structure, and a rib. The tapering structure is configured such that the cross-sectional area of ​​the exhaust pipe 120 gradually decreases from the first air intake end to the second end of the exhaust pipe.

[0072] Specifically, the exhaust pipe 120 is provided with a wall-breaking structure 126 on the inner wall between the first inlet 1211 and the outlet 122. This allows for the wall-breaking operation of the foam flowing into the exhaust pipe 120 through the first inlet 1211, reducing the possibility of the foam flowing into the exhaust pipe 120 through the first inlet 1211 flowing to the outlet 122. This further reduces the possibility of the foam overflowing into the external environment through the outlet 122 of the exhaust pipe 120, greatly improving the cleanliness of the surrounding environment of the clothing processing equipment 100.

[0073] Furthermore, the cell-wall breaking structure 126 includes at least one of a tapered structure, a bent structure, and a rib. The cell-wall breaking structure 126, such as the tapered structure, the bent structure, and the rib, can increase the possibility of the foam contacting the inner wall of the exhaust pipe 120, thereby realizing the cell-wall breaking operation of the foam and reducing the possibility of the foam overflowing into the external environment through the outlet 122 of the exhaust pipe 120.

[0074] The tapered structure is configured such that the cross-sectional area of ​​the exhaust pipe 120 gradually decreases from the first inlet 1211 to the outlet 122. In other words, the opening area of ​​the first inlet 1211 is larger than the opening area of ​​the outlet 122, thus enabling the exhaust pipe 120 to have a tapered structure and achieve foam cell breaking. It can be understood that the exhaust pipe 120 can be entirely or partially configured as a tapered structure from the first inlet 1211 to the outlet 122.

[0075] Understandably, in some examples, the exhaust pipe 120 is also provided with a wall-breaking structure on the inner wall between the second inlet 1212 and the outlet 122 to break the foam flowing from the second inlet 1212 to the outlet 122, thereby reducing the possibility of the foam overflowing into the external environment through the outlet 122 of the exhaust pipe 120.

[0076] In some possible embodiments provided by this utility model, the first inlet 1211 can be set on the side or top of the cylinder 110, as long as the first inlet 1211 is located above the highest design water level of the cylinder 110. This can expand the arrangement range of the first inlet 1211 and reduce the design requirements.

[0077] In some possible embodiments provided by this utility model, the second inlet 1212 can be set on the side or bottom of the cylinder 110, as long as the second inlet 1212 is located below the lowest design water level of the cylinder 110. This can expand the arrangement range of the second inlet 1212 and reduce the design requirements.

[0078] like Figure 7 and Figure 9 As shown, in some possible embodiments provided by this utility model, the cylinder 110 includes an outer cylinder 113 and an inner cylinder 112. The inner cylinder 112 is rotatably disposed inside the outer cylinder 113. The outer cylinder 113 forms a receiving cavity 111 for containing liquid, and the inner cylinder 112 forms a clothing receiving cavity for containing clothing. The side wall of the inner cylinder 112 is provided with a through hole 141 to connect the inner cylinder 112 and the outer cylinder 113, so that the liquid contained in the outer cylinder 113 can flow into the clothing receiving cavity through the through hole 141 to wet the clothing. By rotating the inner cylinder 112 relative to the outer cylinder 113, the clothing is driven to fall from a height and hit the inner cylinder 112, thereby realizing the washing of the clothing.

[0079] In the above embodiment, the first air inlet is connected to the top wall of the outer cylinder 113. Specifically, the first inlet 1211 of the exhaust pipe 120 can be connected to the side wall or top wall of the outer cylinder 113. For example, if the side wall or top wall of the outer cylinder 113 is provided with a first connecting hole, the first inlet 1211 of the exhaust pipe 120 is connected to the outer cylinder 113 through the first connecting hole.

[0080] like Figure 1 , Figure 3 , Figure 5 and Figure 7As shown, the first inlet 1211 can be set on the top wall of the outer drum 113. Since the highest design water level of the drum 110 of the washing machine is usually in the middle or slightly above the middle position, setting the first inlet 1211 on the top wall of the outer drum 113 can ensure that the distance between the first inlet 1211 and the highest design water level of the drum 110 is large enough. This can reduce the possibility that the liquid surface will shake under the action of the movement of the drum 110 and the impact of the clothes during the washing process of the clothes handling equipment 100, causing the foam on the liquid surface to flow into the first inlet 1211. This can further reduce the possibility that the foam in the receiving cavity 111 will overflow into the external environment through the outlet 122 of the exhaust pipe 120, and greatly improve the cleanliness of the surrounding environment of the clothes handling equipment 100.

[0081] Understandably, in other examples, the first inlet 1211 may also be connected to the side wall of the outer cylinder 113, with the top of the first inlet 1211 flush with the top wall of the outer cylinder 113, to ensure that the distance between the first inlet 1211 and the highest design water level of the cylinder 110 is large enough to reduce the possibility of foam on the liquid surface flowing into the first inlet 1211 due to shaking.

[0082] In the above embodiments, the second inlet 1212 of the exhaust pipe 120 can be connected to the side wall or bottom wall of the outer cylinder 113. For example, if the side wall or bottom wall of the outer cylinder 113 is provided with a second connection hole, the second inlet 1212 of the exhaust pipe 120 is connected to the outer cylinder 113 through the second connection hole.

[0083] Furthermore, such as Figure 2 , Figure 3 , Figure 5 and Figure 9 As shown, the second air inlet of the exhaust pipe 120 is connected to the side wall of the outer cylinder. Specifically, the second inlet 1212 is connected to the side wall of the outer cylinder 113. Since the garment processing equipment 100 is typically compact in height, connecting the second inlet 1212 to the bottom wall of the outer cylinder 113 would cause part of the exhaust pipe 120 structure to occupy space at the bottom of the outer cylinder 113, which would be detrimental to the arrangement of other components and would require changing the original layout of other components located at the bottom of the outer cylinder 113. In this embodiment, by connecting the second inlet 1212 to the side wall of the outer cylinder 113, the exhaust pipe 120 can be installed on the side of the outer cylinder 113 without changing the original layout of other components at the bottom of the outer cylinder 113. This design is simple, easy to operate, and suitable for widespread application.

[0084] like Figure 4 and Figure 5As shown, in some possible embodiments provided by this utility model, the garment processing device 100 further includes a housing 140 and a drain pipe 130. The housing 140 is disposed outside the cylinder 110, providing good support and protection for the cylinder 110. The drain pipe 130 is disposed between the housing 140 and the cylinder 110, and connects the receiving cavity 111 to the external environment. Thus, the liquid in the receiving cavity 111 can be discharged to the external environment through the drain pipe 130, realizing the drainage operation of the garment processing device 100.

[0085] In one example, the exhaust pipe 120 is located between the cylinder 110 and the shell 140, and the second end of the exhaust pipe 120 is connected to the drain pipe 130. Specifically, the outlet 122 of the exhaust pipe 120 is connected to the drain pipe 130, so that the outlet 122 of the exhaust pipe 120 is connected to the external environment through the drain pipe 130. Thus, the exhaust pipe 120 enables communication between the interior of the receiving cavity 111 and the external environment, providing a flow space for the gas in the receiving cavity 111 to be discharged. Meanwhile, since the drain pipe 130 of the clothing processing equipment 100 is usually connected to the drain outlet of the sewer in the application scenario, if foam flows into the exhaust pipe 120, since the outlet 122 of the exhaust pipe 120 is connected to the drain pipe 130 and the drain pipe 130 is connected to the drain outlet of the sewer, the foam in the exhaust pipe 120 is directly discharged to the drain outlet of the sewer through the drain pipe 130, and will not pollute the environment around the clothing processing equipment 100. This ensures the cleanliness of the environment around the clothing processing equipment 100 and improves the user experience.

[0086] In another example, the exhaust pipe 120 is located between the cylinder 110 and the housing 140. The housing 140 has a through hole 141. The second end of the exhaust pipe 120 communicates with the through hole 141 of the housing 140. The garment processing device 100 also includes a transition pipe located outside the housing 140 that connects the through hole 141 and the drain pipe 130. Specifically, the outlet 122 of the exhaust pipe 120 communicates with the through hole 141. The garment processing device 100 also includes a transition pipe located outside the housing 140 and communicating with the through hole 141 and the drain pipe 130. Thus, the exhaust pipe 120, the transition pipe, and the drain pipe 130 enable communication between the interior and exterior environments of the receiving cavity 111, providing a flow space for the gas to be discharged from the receiving cavity 111. Meanwhile, since the drain pipe 130 of the clothing processing equipment 100 is usually connected to the drain outlet of the sewer in the application scenario, if foam flows into the exhaust pipe 120, the foam in the exhaust pipe 120 will be discharged directly to the drain outlet of the sewer through the outlet 122, the transition pipe, and the drain pipe 130, and will not pollute the environment around the clothing processing equipment 100. This ensures the cleanliness of the environment around the clothing processing equipment 100 and improves the user experience.

[0087] In some possible embodiments provided by this utility model, the clothing processing device 100 further includes: a water collection device, which is disposed outside the cylinder 110, and the second end of the exhaust pipe 120 is connected to the water collection device. Specifically, the outlet 122 at the second end of the exhaust pipe 120 is connected to the water collection device.

[0088] The water collection device is used to collect liquids. Therefore, if foam flows into the exhaust pipe 120, since the outlet 122 of the exhaust pipe 120 is connected to the water collection device, the foam in the exhaust pipe 120 is directly discharged into the water collection device and collected in the water collection device. It will not cause pollution to the surrounding environment of the clothing processing equipment 100, thus ensuring the cleanliness of the surrounding environment of the clothing processing equipment 100 and improving the user experience.

[0089] Understandably, the garment processing device 100 also includes a housing 140 disposed outside the drum 110. A water collection device can be disposed between the housing 140 and the drum 110, or outside the housing 140. The water collection device is detachably connected to the housing 140 to facilitate removal from the housing 140 for processing the collected liquid. Alternatively, the water collection device can be connected to a drain pipe 130 to discharge the collected liquid through the drain pipe 130 to the drain outlet of the sewer pipe.

[0090] like Figure 4 and Figure 5 As shown, in some possible embodiments provided by this utility model, the clothing processing device 100 further includes: a housing 140, an electrical component 150, and a connecting pipe. The housing 140 is disposed outside the cylinder 110, providing support and protection for the cylinder 110. The electrical component 150 is disposed between the housing 140 and the cylinder 110, and may include an electronic control board, a motor, a fan, a heater, etc. The connecting pipe is disposed between the housing 140 and the cylinder 110, with its first end connected to the second end of the exhaust pipe 120, and its second end extending between the housing 140 and the cylinder 110, and positioned away from the electrical component. Specifically, the first end of the connecting pipe is connected to the outlet 122, and the second end extends between the housing 140 and the cylinder 110, and is positioned away from the electrical component 150.

[0091] Because the inlet 121 of the exhaust pipe 120 in this embodiment is located outside the designed washing water level range of the drum 110, the probability of foam entering the exhaust pipe 120 is small, and the probability of foam overflowing through the outlet 122 of the exhaust pipe 120 is even smaller. Therefore, by connecting the first end of the connecting pipe to the outlet 122 of the exhaust pipe 120, and extending the second end of the connecting pipe between the housing 140 and the drum 110 and away from the electrical component 150, if foam flows into the exhaust pipe 120, the foam in the exhaust pipe 120 will be discharged through the drain pipe 130 and the connecting pipe to the portion between the housing 140 and the drum 110 away from the electrical component 150. Since this portion of foam is small and discharged inside the housing 140, away from the electrical component 150, it will not damage the electrical component 150, ensuring the good reliability of the clothing processing equipment 100. At the same time, it will not pollute the surrounding environment of the clothing processing equipment 100, ensuring the cleanliness of the surrounding environment of the clothing processing equipment 100 and improving the user experience.

[0092] Specifically, no electrical component 150 is installed on the outside of the drum 110 at the left front of the garment handling device 100, so the second end of the connecting pipe can be extended to the outside of the drum 110 at the left front of the garment handling device 100. It is understood that the second end of the connecting pipe can also be extended to other locations that meet the requirements.

[0093] like Figure 10 and Figure 11 As shown, in some possible embodiments provided by this utility model, the exhaust pipe 120 is further provided with a connecting joint 125 installed at the second end of the exhaust pipe. Specifically, the exhaust pipe 120 is further provided with a connecting joint 125 installed at the outlet 122. The provision of the connecting joint 125 facilitates the connection of the outlet 122 of the exhaust pipe 120 with other pipes such as transition pipes, connecting pipes, and drain pipes 130, and is simple to operate and easy to assemble and disassemble.

[0094] Furthermore, the connecting joint 125 located at the outlet also has a certain cell-breaking effect on the foam, which can further reduce the possibility of foam overflowing from the outlet 122 of the exhaust pipe 120.

[0095] like Figure 10 and Figure 11 As shown, the exhaust pipe 120 further includes a spring clip 127, which can reliably and stably fix the inlet 121 and / or outlet 122 of the exhaust pipe 120 at the docking position, thereby improving the reliability and sealing of the connection between the inlet 121 of the exhaust pipe 120 and the cylinder 110, and improving the reliability and sealing of the connection between the outlet 122 of the exhaust pipe 120 and the docking pipeline.

[0096] Specifically, when the exhaust pipe 120 includes a first conduit 123, the spring clip 127 can be disposed at the first inlet 1211 and / or outlet 122 of the first conduit 123. When the exhaust pipe 120 includes a second conduit 124, the spring clip 127 can be disposed at the second inlet 1212 and / or outlet 122 of the second conduit 124.

[0097] like Figure 10 and Figure 11 As shown, the exhaust pipe 120 further includes a spring clip 127, which can reliably and stably fix the inlet 121 and / or outlet 122 of the exhaust pipe 120 at the docking position, thereby improving the reliability and sealing of the connection between the inlet 121 of the exhaust pipe 120 and the cylinder 110, and improving the reliability and sealing of the connection between the outlet 122 of the exhaust pipe 120 and the docking pipeline.

[0098] Specifically, when the exhaust pipe 120 includes a first conduit 123, the spring clip 127 can be disposed at the first inlet 1211 and / or outlet 122 of the first conduit 123. When the exhaust pipe 120 includes a second conduit 124, the spring clip 127 can be disposed at the second inlet 1212 and / or outlet 122 of the second conduit 124.

[0099] Alternatively, the exhaust pipe 120 can be directly led from the drum 110 of the washing machine to the water and air circulation branch such as the detergent dispensing box of the clothes processing device 100, so that any overflow bubbles may directly enter the internal circulation loop of the clothes processing device 100.

[0100] In summary, the clothing processing device 100 provided by this utility model can be a drum washing machine, or the clothing processing device 100 can also include a drying channel, that is, the clothing processing device 100 can be a washer-dryer combo machine with drying function.
