[0033] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0034] As described in the background section, with the improvement of people's living standards, the demand for clothing care is developing towards refinement and intelligence. In recent years, small household washing machines have experienced rapid growth in the market due to their advantages such as energy saving and environmental protection, small footprint, and suitability for washing delicate clothing. However, due to their small washing capacity, these products are more prone to foam overflow when users add too much detergent, which not only affects the washing effect but may also cause machine malfunctions and potential leaks.

[0035] See Figures 1 to 5As shown, in order to solve the above problems, according to one aspect of this application, an embodiment of this application provides a garment processing device including: a housing, a roller module, and a defoaming module, wherein the roller module includes an outer cylinder 11, the outer cylinder 11 is disposed inside the housing, and a vent is provided on the side wall of the outer cylinder 11, the vent communicating with the interior of the outer cylinder 11 and the interior cavity of the housing; the defoaming module is disposed inside the housing and communicates with the vent, the defoaming module is capable of spraying defoaming liquid into the vent, the defoaming liquid is capable of contacting and defoaming the foam in the vent; and / or the defoaming liquid is capable of contacting and defoaming the foam inside the outer cylinder 11 through the vent. The garment processing device provided in this embodiment connects the interior of the outer drum 11 with the internal cavity of the housing through a venting section. During the washing process, the venting section effectively balances the pressure difference between the inside and outside of the drum module, preventing abnormal vibration and noise caused by pressure fluctuations. At the same time, the defoaming module provided in this embodiment can directionally spray defoaming liquid into the venting section. The defoaming liquid can contact the foam in the venting section and also contact the foam inside the outer drum 11 through the venting section. Through the kinetic energy and shear force of the defoaming liquid, the foam structure can be destroyed, thereby preventing foam from overflowing from the venting section. By instantly dissolving the foam in the venting section and inside the outer drum 11, the overflow phenomenon caused by foam accumulation can be avoided to a certain extent, improving the reliability of the garment processing device.

[0036] It should be noted that the defoaming liquid in this embodiment is water. When the defoaming liquid is water, it destroys the foam structure through the kinetic energy and shear force during spraying, thus achieving foam dissolution through a physical means. Of course, in other embodiments, the defoaming liquid provided in this embodiment can also be a chemical agent or mixed solution for eliminating foam. When the defoaming liquid is a chemical agent or mixed solution for eliminating foam, it can not only destroy the foam structure through the kinetic energy and shear force during spraying, but also reduce the surface tension of the foam film through its presence of surfactants and other defoaming components, thereby achieving foam dissolution through a combination of physical and chemical methods.

[0037] The shell refers to the main frame that forms the external support structure of the clothing processing device. It is usually made of metal or engineering plastic and is used to house and protect the internal functional components. The shell provided in this embodiment has a structural space inside for installing other modules and has the necessary openings and connection structures.

[0038] See Figure 1As shown, the drum module is the core functional component of the garment handling device, comprising a double-layer structure consisting of an outer drum 11 and an inner drum 12. The outer drum 11 is fixedly installed inside the housing, serving as a stationary container; the inner drum 12 is rotatably disposed inside the outer drum 11, used to hold and agitate the garments. In this embodiment, the drum module is responsible for fulfilling the main functions of loading, washing, and dehydrating the garments. It should be noted that in this embodiment, the outer drum 11 is made of corrosion-resistant materials such as stainless steel, forming a space for holding the washing liquid, and a certain gap is maintained between the outer drum 11 and the housing, forming an internal cavity within the housing.

[0039] See Figures 1 to 4 As shown in some specific embodiments, the defoaming module in this embodiment includes a liquid spraying and venting component 21. The liquid spraying and venting component 21 is provided with a liquid delivery channel 211 and a venting channel 212. The liquid delivery channel 211 communicates with the venting section and is used to deliver defoaming liquid to the venting section. When no defoaming liquid is delivered through the liquid delivery channel 211, the venting channel 212 communicates with the interior of the outer cylinder 11 through the venting section to vent the gas inside the outer cylinder 11. By providing a liquid delivery channel 211 and a venting channel 212 within the liquid spraying and venting component 21, the defoaming module can deliver defoaming liquid to the venting section through the liquid delivery channel 211, and vent the gas inside the outer cylinder 11 through the venting channel 212 when no defoaming liquid is delivered through the liquid delivery channel 211. This achieves the defoaming function while preventing the accumulation of internal gas pressure in the outer cylinder.

[0040] See Figure 1As shown, in some specific embodiments, the venting part in this embodiment includes a vent 111, which connects the interior of the outer cylinder 11 with the internal cavity of the shell. The first end of the infusion channel 211 is connected to the vent 111 and is used to deliver defoaming liquid into the vent 111. The first end of the venting channel 212 is connected to the infusion channel 211, and the second end of the venting channel 212 is connected to the internal cavity of the shell. When the infusion channel 211 is not delivering defoaming liquid, the vent 111 is connected to the internal cavity of the shell in sequence through the infusion channel 211 and the venting channel 212. The first end of the infusion channel 211 is connected to the vent 111, allowing the defoaming module to deliver defoaming liquid to the vent through the infusion channel 211. The two ends of the venting channel 212 are connected to the infusion channel 211 and the internal cavity of the housing, respectively. This allows the defoaming module to balance the internal and external air pressure difference of the drum module by connecting the vent 111 to the internal cavity of the housing through the infusion channel 211 and the venting channel 212 when no defoaming liquid is being delivered through the infusion channel 211, thereby improving the operating efficiency and reliability of the garment processing device. It should be noted that in this embodiment, the internal cavity of the housing is connected to the external environment through gaps or other structures on the housing. Therefore, in this embodiment, the second end of the venting channel 212 is connected to the internal cavity of the housing. This is to allow the second end of the venting channel 212 to indirectly connect to the external environment through the internal cavity of the housing, thus allowing the gas inside the outer cylinder 11 to be discharged to the external environment. Of course, in other embodiments, the second end of the venting channel 212 in this embodiment can also be directly connected to the external environment through gaps or other structures on the housing.

[0041] See Figure 1 As shown, the vent 111 in this embodiment is a venting channel opened on the side wall of the outer drum 11. The diameter and number of vents 111 are designed according to actual needs. The main function of the vent 111 is to connect the inside of the outer drum 11 with the internal cavity of the shell, balancing the pressure difference between the inside and outside caused by temperature changes and mechanical movement during the washing process, and preventing malfunctions of the clothes handling device caused by abnormal pressure. It should be noted that the internal cavity of the shell refers to the sealed space formed between the inner wall of the shell and the outer wall of the outer drum 11. This space is connected to the inside of the outer drum 11 through the vent 111. The internal cavity of the shell acts as a pressure buffer area, which can effectively disperse and regulate pressure fluctuations.

[0042] In another embodiment, the venting part includes a venting pipe that connects the interior of the outer cylinder 11 to the internal cavity of the shell. Of course, in other embodiments, the venting part can also be any other device or structure capable of connecting the interior of the outer cylinder 11 to the internal cavity of the shell.

[0043] In some specific embodiments, the venting channel 212 is inclined towards the infusion channel 211 along the direction of defoaming liquid delivery. It should be noted that in this embodiment, the venting channel 212, inclined in a specific direction, forms a gradually decreasing flow channel structure at its intersection with the infusion channel 211. This structure features a channel cross-sectional area that gradually decreases along the liquid flow direction, and the channel wall has a continuous, smooth, converging curved surface. This gradually decreasing flow channel structure can guide the defoaming liquid to form a directional jet pointing towards the vent 111 during delivery. Through the convergence effect of the flow channel, the flow velocity of the defoaming liquid can be increased, enhancing the jet kinetic energy, thereby enabling the defoaming liquid to be efficiently delivered to the vent 111 area. Setting the venting channel 212 inclined towards the infusion channel 211 along the direction of defoaming liquid delivery allows the defoaming liquid to be efficiently delivered to the vent 111 during defoaming operations in the defoaming module, achieving rapid defoaming.

[0044] In some specific embodiments, the spray venting component 21 in this embodiment integrates the functions of defoaming liquid delivery and gas emission through the integrated liquid delivery channel 211 and venting channel 212. The venting channel 212 is set to be inclined towards the liquid delivery channel 211 along the defoaming liquid delivery direction. This ensures that the defoaming liquid can be efficiently delivered to the venting port 111 area for rapid defoaming during defoaming operations, and also ensures that the venting port 111 can maintain normal air pressure balance through the liquid delivery channel 211 and venting channel 212 in the non-defoaming state. This significantly improves the working stability and reliability of the clothing treatment device.

[0045] When the infusion channel 211 is delivering defoaming liquid, some of the defoaming liquid may flow into the venting channel 212 and enter the outside of the housing through the venting channel 212, affecting the reliability of the clothing treatment device.

[0046] To solve the above problem, see Figure 2As shown, in some specific embodiments, the venting channel 212 and the infusion channel 211 in this embodiment have an inclined angle; the size of the inclined angle is α, where α ≤ 45° or α ≤ 60°. By setting the inclined angle between the venting channel 212 and the infusion channel 211 to no more than 45° or 60°, a tapered flow channel structure can be formed at the intersection of the venting channel 212 and the infusion channel 211. This generates sufficient centripetal force on the defoaming liquid in the infusion channel 211, ensuring the precise guidance of the liquid to the venting port 111 and preventing the defoaming liquid from flowing out of the venting channel 212. The size of the inclined angle affects the magnitude of the centripetal force generated by the tapered flow channel structure on the defoaming liquid. The larger the inclined angle, the smaller the centripetal force generated by the tapered flow channel structure on the defoaming liquid. When the defoaming liquid enters the infusion channel 211 at normal infusion pressure... The flow rate of the defoaming liquid is relatively slow, so a larger centripetal force is required to guide its flow. In this case, the tilt angle needs to be set to no more than 45° to provide sufficient centripetal force. When the defoaming liquid enters the infusion channel 211 at a higher inlet pressure, i.e., greater than the normal inlet pressure, the centripetal force can be appropriately reduced due to the faster flow rate of the defoaming liquid. In this case, the tilt angle can be relaxed to no more than 60°. The normal inlet pressure refers to the liquid pressure applied when the defoaming liquid enters the infusion channel 211 under normal infusion conditions. This pressure allows the defoaming liquid to flow at a stable flow rate and ensures that the defoaming liquid does not flow back.

[0047] It should be noted that, in this embodiment, the central axis of the venting channel 212 refers to the central axis of symmetry of the venting channel 212, and the central axis of the infusion channel 211 refers to the central axis of symmetry of the infusion channel 211. The included angle is the acute angle formed when the central axes of the two channels intersect in three-dimensional space. This included angle is used to define the spatial orientation relationship between the venting channel 212 and the infusion channel 211. Its numerical range a≤45° or a≤60° indicates that the two channels are arranged in a non-orthogonal oblique connection.

[0048] In some embodiments, when the angle of inclination is constant, the central axis of the infusion channel 211 is used as a fixed axis, and the central axis of the venting channel 212 rotates around the fixed axis for one revolution. Its trajectory forms a virtual cone surface. Any generatrix direction of the virtual cone surface can be used as an optional orientation of the central axis of the venting channel 212 under the angle of inclination. By adjusting the specific orientation of the central axis of the venting channel on the virtual cone surface, different installation spaces or airflow guidance requirements can be adapted.

[0049] In some specific embodiments, the venting channel 212 in this embodiment is inclined relative to the infusion channel 211. Setting the venting channel 212 to be inclined upward relative to the infusion channel 211 can make the wall surface of the venting channel 212 form an obtuse angle with the direction of gravity. When the defoaming liquid is transported through the infusion channel 211, the defoaming liquid will flow directionally along the wall of the infusion channel 211 towards the vent 111 due to gravity, thereby further preventing the defoaming liquid from flowing out of the venting channel 212.

[0050] In some embodiments, a liquid-repellent and breathable membrane is provided inside the venting channel 212 in this embodiment to seal the venting channel 212. By providing a liquid-repellent and breathable membrane inside the venting channel 212, a one-way gas discharge path can be formed in the venting channel 212, thereby further preventing the defoaming liquid from flowing out of the venting channel 212.

[0051] In some embodiments, the spray venting component 21 in this embodiment is a Venturi tee structure. By setting the spray venting component 21 to a Venturi tee structure, negative pressure can be generated in the venting channel 212 when the defoaming liquid is transported through the infusion channel 211. Through the negative pressure in the venting channel 212, the defoaming liquid can be prevented from flowing out of the venting channel 212 during the transportation process.

[0052] See Figure 1 As shown, in some specific embodiments, the garment processing device in this embodiment further includes a material box module 30, which is installed in the housing and its interior is connected to the internal cavity of the housing; the second end of the venting channel 212 is connected to the interior of the material box module 30. By connecting the second end of the venting channel 212 to the interior of the material box module 30 and utilizing the existing ventilation structure of the material box module 30 to achieve gas discharge, the gas discharge path of the outer cylinder 11 of the garment processing device is optimized, so that the gas inside the outer cylinder 11 can form a continuous exhaust channel through the liquid delivery channel 211, the venting channel 212, and the material box module 30, thereby improving the gas discharge efficiency. Furthermore, by fully utilizing the structural characteristics of the material box module 30, the garment processing device in this embodiment does not require additional dedicated exhaust components, simplifying the structure of the garment processing device and reducing production costs. While maintaining the internal air pressure balance of the outer cylinder 11 of the garment processing device, it avoids the gas inside the outer cylinder 11 being directly discharged to the user's operating area, thereby improving the safety and comfort of using the garment processing device. It should be noted that in this embodiment, the internal cavity of the housing is connected to the external environment through gaps or other structures on the housing. Therefore, in this embodiment, the interior of the material box module 30 is configured to communicate with the internal cavity of the housing, the purpose of which is to allow the interior of the material box module 30 to indirectly communicate with the external environment through the internal cavity of the housing. Of course, in other embodiments, the interior of the material box module 30 in this embodiment can also be directly connected to the external environment through gaps or other structures on the housing.

[0053] It should be noted that in this embodiment, the material box module 30 is fixedly installed on the housing of the device, and its interior is provided with a ventilation structure that communicates with the internal cavity of the housing to realize the exchange of gas inside and outside the material box module 30. In this embodiment, the second end of the venting channel 212 is connected to the internal cavity of the material box module 30, so that the gas can be discharged from the inside of the outer cylinder 11 to the material box module 30 through the venting channel 212, and then discharged to the internal cavity of the housing through the ventilation structure that connects the material box module 30 with the internal cavity of the housing, and finally discharged to the external environment through the gaps and other structures on the housing. Of course, in other embodiments, the material box module 30 in this embodiment can also be detachably or slidably installed on the housing. When the material box module 30 is detachably installed on the housing, the maintenance convenience of the material box module 30 can be improved. When it is necessary to clean or replace the material box module 30, the material box module 30 can be easily disassembled and reassembled, making it convenient to replace the material box module 30 with different functions according to different usage needs. When the material box module 30 is slidably installed on the housing, the space occupied by the material box module 30 outside the clothing processing device can be saved, the space utilization rate of the clothing processing device can be optimized, and the layout flexibility of the clothing processing device can be improved.

[0054] In some embodiments, the material box module 30 in this embodiment is a fixed structure, including a box body, a ventilation grille and a connection interface. The box body is fixed to the preset installation position of the housing by bolts, the ventilation grille is provided on the side wall of the box body to realize the exchange of internal and external gases, and the connection interface is connected to the second end of the venting channel 212 by a snap-fit ​​sealing connection.

[0055] In some embodiments, the material box module 30 in this embodiment has a detachable structure, including a drawer-type box, a filter assembly and a quick-connect interface. The drawer-type box is slidably installed on the housing via a slide rail. The filter assembly is located on the back of the box to form a ventilation structure. The quick-connect interface and the second end of the venting channel 212 are magnetically sealed to achieve modular disassembly and assembly.

[0056] See Figure 1As shown in some specific embodiments, the garment processing device in this embodiment further includes a spray liquid supply module, and the defoaming module further includes a flow direction switching component. The outlet end of the spray liquid supply module is connected to the inlet end of the flow direction switching component. The flow direction switching component has a first outlet end, which is connected to the second end of the delivery channel 211. The spray liquid supply module can deliver defoaming liquid into the delivery channel 211 through the flow direction switching component. By setting the cooperative structure of the spray liquid supply module and the flow direction switching component, a supply system for defoaming liquid that can be directionally delivered is constructed, realizing the modular design of the defoaming function and improving the functional integration of the garment processing device. At the same time, through the cooperative structure of the spray liquid supply module and the flow direction switching component, the defoaming liquid delivery path of the garment processing device can also be optimized, reducing pipeline layout, reducing pressure loss during the defoaming liquid delivery process, and improving defoaming efficiency.

[0057] It should be noted that, in this embodiment, the spray supply module refers to a functional component used for storing and pumping defoaming liquid, and the flow direction switching component is a valve body mechanism in the defoaming module used to control the liquid flow direction. It includes at least one inlet end for receiving the input of defoaming liquid and at least one first outlet end for outputting defoaming liquid. The spray supply module forms fluid communication with the inlet end of the flow direction switching component through its outlet end, and the first outlet end of the flow direction switching component is connected to the second end of the delivery channel 211, thereby constructing a complete defoaming liquid delivery path.

[0058] See Figure 1 As shown, in some specific embodiments, the spray supply module in this embodiment includes a supply pipeline 41 and a spray valve 42. The inlet end of the spray valve 42 is connected to the outlet end of the supply pipeline 41, and the outlet end of the spray valve 42 forms the outlet end of the spray supply module. The spray valve 42 has an open state that connects the outlet end of the supply pipeline 41 to the outlet end of the spray valve 42, and a closed state that isolates the outlet end of the supply pipeline 41 from the outlet end of the spray valve 42. By setting the cooperative structure of the spray valve 42 and the supply pipeline 41, a controllable liquid delivery system is established. The on / off state of the spray valve 42 is used to precisely control the liquid flow, ensuring that the defoaming liquid or spray liquid is supplied as needed. In this embodiment, the spray supply module directly integrates the spray valve 42 at the end of the supply pipeline 41, forming a compact modular structure and reducing intermediate connecting parts. The valve body structure of the spray valve 42 in this embodiment is a standardized design, reducing the maintenance complexity of the garment treatment device.

[0059] It should be noted that the spray valve 42 in this embodiment is a control valve installed on the liquid supply pipeline 41. It includes an inlet end and an outlet end, wherein the inlet end of the spray valve 42 is connected to the outlet end of the liquid supply pipeline 41, and the outlet end of the spray valve 42 constitutes the final outlet of the spray liquid supply module. The spray valve 42 in this embodiment has two working states. In the open state, the liquid supply pipeline 41 and the outlet end of the spray valve 42 form a communication path, allowing the defoaming liquid to pass through. In the closed state, the passage between the liquid supply pipeline 41 and the outlet end of the spray valve 42 is blocked, preventing the flow of defoaming liquid. By controlling the working state of the spray valve 42, precise start and stop control of the defoaming liquid can be achieved.

[0060] See Figure 5 As shown, in some specific embodiments, the flow direction switching component in this embodiment has a second liquid outlet end; the garment processing device also includes a spray module, which is disposed inside the housing. The liquid inlet end of the spray module is connected to the second liquid outlet end, and the liquid outlet end of the spray module is located in a predetermined spray area of ​​the housing, used to spray spray liquid into the predetermined spray area. The spray supply module can deliver spray liquid to the spray module through the flow direction switching component. By setting the spray module and the flow direction switching component with the second liquid outlet end, a multi-channel liquid distribution system is constructed. The flow direction switching component realizes the separation of defoaming liquid and spray liquid, optimizing the liquid delivery path; the spray module is directly connected to the second liquid outlet end to form the shortest delivery path, improving spray efficiency; the liquid outlet end of the spray module is oriented in the predetermined spray area to ensure that the spray liquid accurately covers the target position, realizing precise area spraying; the modular design allows the defoaming and spraying functions to share the same liquid supply system, simplifying the structure of the garment processing device while improving the integration of the garment processing device.

[0061] It should be noted that, in this embodiment, the spray liquid supply module refers to an integrated functional component used for storing and transporting defoaming liquid and spray liquid. In this embodiment, the defoaming liquid and spray liquid use the same liquid medium. By sharing the liquid source for both the defoaming liquid and the spray liquid, the structure of the supply pipeline 41 can be simplified, the number of independent pipelines can be reduced, the integration and space utilization of the garment processing device can be improved, and unified control of liquid transport parameters can be facilitated. It should be understood that using the same liquid medium for both the defoaming liquid and the spray liquid in this embodiment is only a preferred embodiment and does not constitute a limitation on the technical solution. Depending on actual application requirements, the defoaming liquid and the spray liquid may also use liquid media with different characteristics.

[0062] In some embodiments, the outer cylinder 11 of this embodiment is provided with a spray nozzle 112 that communicates with the inside of the outer cylinder 11. The liquid outlet end of the spray module in this embodiment is connected to the spray nozzle 112 and is used to spray spray liquid onto the spray nozzle 112 of the outer cylinder 11. It should be noted that the spray nozzle 112 in this embodiment is the door seam spray nozzle of the garment treatment device. Of course, in other embodiments, the spray nozzle 112 in this embodiment can also be a spray nozzle in other positions.

[0063] It should be noted that, in this embodiment, the spray module refers to a functional component disposed within the housing for performing liquid spraying. The spray module includes an inlet end and an outlet end, wherein the inlet end of the spray module is connected to the second outlet end of the flow direction switching component, and the outlet end of the spray module extends to a predetermined spraying area of ​​the housing, wherein the predetermined spraying area refers to a specific spatial location that needs to receive liquid spraying. In this embodiment, the spray supply module can supply spraying liquid to the spray module via the second outlet end of the flow direction switching component, and finally spray the liquid precisely to the predetermined area through the outlet end of the spray module.

[0064] In some specific embodiments, the flow direction switching component in this embodiment includes a reversing valve 22. The reversing valve 22 has one inlet end and two outlet ends. The inlet end of the reversing valve 22 is connected to the outlet end of the spray supply module, and the two outlet ends of the reversing valve 22 are respectively connected to the second end of the delivery channel 211 and the inlet end of the spray module. The reversing valve 22 has the function of connecting the outlet end of the spray supply module with the second end of the delivery channel 211, isolating the defoaming state between the outlet end of the spray supply module and the inlet end of the spray module, and connecting the outlet end of the spray supply module with the inlet end of the spray module, isolating the spraying state between the outlet end of the spray supply module and the second end of the delivery channel 211. By setting a reversing valve 22 with bidirectional diversion function, precise liquid distribution from a single liquid supply source to different functional modules is achieved, that is, directional liquid distribution from the spray supply module to the spray module or the defoaming module, simplifying pipeline connection and improving space utilization.

[0065] It should be noted that the reversing valve 22 in this embodiment is a control valve body with flow distribution function. Structurally, it has an inlet end for receiving the liquid delivered by the spray supply module, and two outlet ends connected to the second end of the delivery channel 211 and the inlet end of the spray module, respectively. The defoaming state in this embodiment refers to one of the operating modes of the reversing valve 22. When the reversing valve 22 is in the defoaming state, the inlet end of the reversing valve 22 is connected to the second end of the delivery channel 211 to form a defoaming liquid delivery path, while simultaneously blocking the spray path. The spraying state is another operating mode of the reversing valve 22. When the reversing valve 22 is in the spraying state, the inlet end of the reversing valve 22 is connected to the inlet end of the spray module to form a spray liquid delivery path, while simultaneously blocking the defoaming path. In this embodiment, the reversing valve 22 achieves a single liquid supply system, i.e., directional liquid distribution from the spray supply module to different functional modules, by switching between these two operating states.

[0066] In some embodiments, the second end of the infusion channel 211 in this embodiment is sealed to the inlet end of the reversing valve 22 via a pipeline, the second end of the venting channel 212 is sealed to the material box module 30 via a pipeline, and the first end of the infusion channel 211 is sealed to the venting port 111 via a pipeline.

[0067] In some specific embodiments, the bottom of the outer tub 11 in this embodiment is provided with a drain outlet communicating with the interior of the outer tub 11. The garment handling device also includes a drain module, which is disposed on the housing. The inlet end of the drain module is connected to the drain outlet, and the outlet end of the drain module is located outside the housing, used to discharge the liquid inside the outer tub 11 to the outside of the housing. It should be noted that the drain outlet in this embodiment is an open structure for discharging the liquid inside the outer tub 11. The drain module refers to a liquid discharge component installed on the housing, which includes an inlet end and an outlet end. The inlet end of the drain module is connected to the drain outlet to form a liquid channel, and the outlet end of the drain module extends to the outside of the housing to achieve liquid discharge. The drain module achieves the directional discharge function of washing wastewater by establishing a communication path between the interior of the outer tub 11 and the outside of the housing. Setting the drain outlet at the bottom of the outer tub 11 is beneficial to achieving complete drainage of the liquid.

[0068] In some specific embodiments, the clothing processing device in this embodiment establishes an efficient liquid discharge system for the outer cylinder 11 by setting a drain outlet at the bottom of the outer cylinder 11 and configuring a corresponding drainage module. The drainage module enables rapid and directional discharge of liquid inside the outer cylinder 11, thereby improving drainage efficiency. It should be noted that in this embodiment, the drain outlet is located at the lowest position at the bottom of the outer cylinder 11, and gravity is used to ensure that the liquid is completely drained, avoiding residue.

[0069] In some embodiments, the drainage module in this embodiment includes a drainage pump, a first drainage pipe and a second drainage pipe, wherein the inlet end of the drainage pump is connected to the outlet end through the first drainage pipe, and the outlet end of the drainage pump is connected to the outside of the housing through the second drainage pipe.

[0070] In some specific embodiments, the garment processing device in this embodiment further includes a control module. The control module is electrically connected to the defoaming module and the spray liquid supply module, and is used to control the operation of the defoaming module and the spray liquid supply module. By setting up a control module and electrically connecting it to the defoaming module and the spray liquid supply module, the control module can achieve precise coordination of defoaming and spraying functions through centralized control, thereby improving the overall processing efficiency. Furthermore, the control module can automatically adjust the defoaming intensity and spraying parameters according to real-time operating conditions to ensure optimal processing results.

[0071] It should be noted that the control module in this embodiment refers to the intelligent control unit in the garment processing device used to coordinate the operation of the system. It forms a control loop with the defoaming module and the spray liquid supply module through electrical connection. The control module precisely regulates the start and stop of the defoaming module, its working intensity, and the timing and flow parameters of liquid delivery of the spray liquid supply module through preset programs or real-time detection signals, so as to realize the coordinated operation of the two functional modules.

[0072] In some specific embodiments, the garment processing device in this embodiment further includes a foam detection module. The foam detection module is disposed within the outer tube 11 and electrically connected to the control module. The foam detection module can detect foam in the outer tube 11 and output a defoaming signal to the control module when the detected foam reaches a certain condition. It should be noted that the foam detection module in this embodiment refers to a sensing device disposed inside the outer tube 11 for real-time monitoring of foam within the outer tube 11. The foam detection module forms a signal transmission loop with the control module through an electrical connection. By setting up the foam detection module, foam in the outer tube 11 can be detected in real time. Electrically connecting the foam detection module to the control module allows the control module to control the defoaming module to operate based on the defoaming signal output by the foam detection module, thereby promptly eliminating foam.

[0073] In some embodiments, the foam detection module in this embodiment includes a foam height detection unit and a first signal processing unit. The foam height detection unit is used to detect the foam height inside the outer cylinder 11. The first signal processing unit is electrically connected to the foam height detection unit and is used to process the signal generated by the foam height detection unit to generate a defoaming signal. When the foam detection module in this embodiment detects that the foam height inside the outer cylinder 11 reaches a preset safety threshold, it can generate and output a defoaming signal to the control module. In this embodiment, the defoaming signal refers to a specific electrical signal representing an excessive foam height, used to trigger the control module to start the corresponding defoaming control program. It should be noted that the foam height detection unit in this embodiment is a water level sensor. The water level sensor indirectly detects the foam height inside the outer cylinder 11 by detecting pressure changes inside the outer cylinder 11. Of course, in other embodiments, the foam height detection unit provided in this embodiment can also be a dedicated foam detection sensor.

[0074] In other embodiments, the foam detection module in this embodiment includes a conductivity detection unit and a second signal processing unit. The conductivity detection unit is used to detect the conductivity of the washing medium inside the outer drum 11. The second signal processing unit is electrically connected to the conductivity detection unit and is used to process the signal generated by the conductivity detection unit to generate a defoaming signal. When the foam detection module in this embodiment detects that the conductivity inside the outer drum 11 reaches a preset safety threshold, it can generate and output a defoaming signal to the control module. In this embodiment, the defoaming signal refers to a specific electrical signal representing an excessive conductivity, used to trigger the control module to start the corresponding defoaming control program. It should be noted that the conductivity detection unit in this embodiment is a conductivity detection sensor. The conductivity detection sensor indirectly detects the foam ratio inside the outer drum 11 by detecting changes in the conductivity of the washing medium inside the outer drum 11.

[0075] In some embodiments, the foam detection module in this embodiment includes a sound wave attenuation detection unit and a third signal processing unit. The sound wave attenuation detection unit is used to detect the attenuation rate of sound waves in the washing medium inside the outer drum 11. The third signal processing unit is electrically connected to the conductivity detection unit and is used to process the signal generated by the sound wave attenuation detection unit to generate a defoaming signal. When the foam detection module in this embodiment detects that the sound wave attenuation rate inside the outer drum 11 reaches a preset safety threshold, it can generate and output a defoaming signal to the control module. In this embodiment, the defoaming signal refers to a specific electrical signal representing an excessive sound wave attenuation rate, used to trigger the control module to start the corresponding defoaming control program. It should be noted that the sound wave attenuation detection unit in this embodiment is a sound wave attenuation detection sensor. The sound wave attenuation detection sensor indirectly detects the foam ratio inside the outer drum 11 by detecting the change in the attenuation rate of sound waves in the washing medium inside the outer drum 11.

[0076] In some specific embodiments, when the clothing processing device provided in this embodiment is washing clothes, if the foam detection module detects through the water level sensor that the foam height inside the outer drum 11 reaches a preset safety threshold, it will generate and output a defoaming signal to the control module. The control module will control the working status of the reversing valve 22, the spray valve 42, and the drain pump, that is, sequentially open the reversing valve 22, the spray valve 42, and the drain pump. Opening the reversing valve 22 means switching the reversing valve 22 to the defoaming state. At this time, the defoaming module sprays defoaming liquid onto the vent of the outer drum 11 to dissolve the foam in the vent of the outer drum 11 and inside the outer drum 11. The drainage module discharges the liquid inside the outer cylinder 11 to the outside of the shell. When the control module detects the disappearance of the high-foam signal, the control module controls the working state of the reversing valve 22 and the spray valve 42, that is, it sequentially closes the spray valve 42 and the reversing valve 22. Closing the reversing valve 22 means switching the reversing valve 22 to the spray state. It should be noted that the control module closes the reversing valve 22 2 to 5 seconds after closing the spray valve 42. By controlling the operation sequence of closing the spray valve 42 2 to 5 seconds in advance and then closing the reversing valve 22, water hammer effect and pressure fluctuation can be avoided, the sealing performance of the valve can be protected, and the service life of the clothing treatment device can be extended.

[0077] In summary, the clothing processing device provided in this embodiment has at least the following beneficial technical effects: The clothing processing device provided in this embodiment connects the interior of the outer drum 11 with the internal cavity of the housing through the venting section. During the washing process of the clothing processing device, the venting section can effectively balance the pressure difference between the inside and outside of the drum module, preventing abnormal vibration and noise caused by pressure fluctuations. At the same time, the defoaming module provided in this embodiment can directionally spray defoaming liquid into the venting section. At this time, the defoaming liquid can come into contact with the foam in the venting section, and can also come into contact with the foam inside the outer drum 11 through the venting section. Through the kinetic energy and shear force of the defoaming liquid, the foam structure can be destroyed, thereby preventing foam from overflowing from the venting section. By instantly dissolving the foam in the venting section and inside the outer drum 11, the overflow phenomenon caused by foam accumulation can be avoided to a certain extent, improving the reliability of the clothing processing device.
