It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.

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.

[0032] 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.

[0033] See Figures 1 to 4 As 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, which includes: a housing, a drum module, a drying module, and a defoaming module. The drum module includes an outer cylinder 11 disposed within the housing. A vent is provided on the side wall of the outer cylinder 11, and the vent connects the interior of the outer cylinder 11 with the internal cavity of the housing. The drying module is disposed within the housing. The defoaming module is disposed within the housing and communicates with the vent. The defoaming module can introduce defoaming gas into the vent, and the defoaming gas can contact and defoam the foam in the vent; and / or, the defoaming gas can contact and defoam the foam inside the outer cylinder 11 through the vent; the drying module is connected to the defoaming module, and the defoaming gas includes circulating air or regenerated air diverted from the drying module. 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. Simultaneously, the defoaming module provided in this embodiment can directionally deliver defoaming gas into the venting section. This defoaming gas can contact the foam in the venting section and also contact the foam inside the outer drum. When the defoaming gas is circulating air, it eliminates the foam in the venting section and inside the outer drum through airflow impact. When the defoaming gas is regenerated air, it rapidly decomposes and eliminates the foam in the venting section and inside the outer drum through the dual effects of hot air heating and airflow impact. The internal foam prevents foam from overflowing from the vent and contaminating the internal cavity of the shell. By instantly dissolving the foam in the vent and the outer cylinder, the overflow phenomenon caused by foam accumulation can be avoided to a certain extent, thus improving the reliability of the garment processing device. In this embodiment, the circulating air is an unheated airflow, and the regenerated air is a heated airflow. The connection between the defoaming module and the vent is a non-sealed connection. In this case, the vent can connect the interior of the outer cylinder 11 and the internal cavity of the shell through the connection gap between the defoaming module and the vent. Of course, in other embodiments, the connection between the defoaming module and the vent in this embodiment can also be a sealed connection. In this case, the defoaming module is provided with a vent structure that connects the internal cavity of the shell and the vent to maintain the venting function of the vent.

[0034] It should be noted that when the defoaming gas uses circulating air, the airflow impact of the defoaming gas on the foam refers to the process where unheated circulating air diverted from the drying module is introduced into the venting section at a certain flow rate and pressure. The mechanical force generated by the gas flow causes the foam film to rupture. That is, the airflow energy of the defoaming gas directly acts on the foam surface, generating shear force and impact force, disrupting the surface tension balance of the foam liquid film. The continuous introduction of defoaming gas forms an airflow field, displacing the gas medium in the foam structure, accelerating the drainage and thinning of the foam liquid film, thereby achieving rapid foam elimination. When the defoaming gas uses regenerated air, in addition to airflow impact, the defoaming gas also disrupts the stability of the foam liquid film through its higher temperature. Specifically, evaporation leads to thinning of the foam liquid film, a decrease in surface tension, an increase in gas expansion pressure, and foam liquid film flow caused by temperature gradient. The combined effect of these factors ultimately leads to the collapse of the foam structure, thereby eliminating the foam. If the foam contains surfactants, high temperature may also disrupt the arrangement of surfactant molecules, further reducing the strength of the foam liquid film.

[0035] 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.

[0036] In some specific embodiments, the drying module in this embodiment is provided with a first defoaming gas outlet 271, which is connected to the defoaming module. Circulating air is transported through the first defoaming gas outlet 271 and the defoaming module to the venting section, or the circulating air is transported through the first defoaming gas outlet 271, the defoaming module, and the venting section to the interior of the outer cylinder 11. By providing the first defoaming gas outlet 271 to connect the drying module and the defoaming module, the circulating air in the drying module can be diverted to the defoaming module, and then introduced into the venting section and the outer cylinder 11 for defoaming. Using the circulating air diverted from the drying module as the defoaming gas eliminates the need for additional energy-consuming devices, thus improving the energy efficiency of the clothing treatment device.

[0037] In some specific embodiments, the drying module in this embodiment has a second defoaming gas outlet 272, which is connected to the defoaming module. Regenerated air is transported to the venting section via the second defoaming gas outlet 272 and the defoaming module, or the regenerated air is transported to the interior of the outer cylinder 11 via the second defoaming gas outlet 272, the defoaming module, and the venting section. By setting the second defoaming gas outlet 272 to connect the drying module and the defoaming module, the regenerated air in the drying module can be diverted to the defoaming module, and then introduced into the venting section and the outer cylinder 11 for defoaming. Using the regenerated air diverted from the drying module as the defoaming gas eliminates the need for additional energy-consuming devices, thus improving the energy efficiency of the clothing treatment device.

[0038] In some specific embodiments, both the first defoaming gas outlet 271 and the second defoaming gas outlet 272 in this embodiment are connected to the defoaming module. By connecting the drying module and the defoaming module through the first defoaming gas outlet 271 and the second defoaming gas outlet 272, the circulating air or regenerated air in the drying module can be diverted to the defoaming module and then introduced into the venting section for defoaming. Using the circulating air or regenerated air diverted from the drying module as the defoaming gas eliminates the need for additional energy-consuming devices, thus improving the energy efficiency of the clothing treatment device.

[0039] In some specific embodiments, when the defoaming gas is regenerated air, the temperature of the defoaming gas in this embodiment is 40°C to 60°C. It should be noted that the defoaming gas in this embodiment refers to the hot airflow generated by the drying module that has a foam-eliminating function, and its temperature range is set to 40°C to 60°C. The temperature range of 40°C to 60°C for the defoaming gas effectively decomposes foam while avoiding damage to clothing or components of the clothing processing device due to excessively high temperatures, thus ensuring a balance between heat energy utilization and defoaming efficiency.

[0040] Specifically, hot air at 40°C to 60°C can break the surface tension of the foam and cause it to rupture, while avoiding poor defoaming effect due to excessively low temperature or energy waste and material thermal aging due to excessively high temperature.

[0041] In some specific embodiments, the defoaming module in this embodiment has an air guide channel, and the venting part includes a vent 111. The vent 111 connects the interior of the outer cylinder 11 with the internal cavity of the shell. The air inlet of the air guide channel is connected to the drying module, and the air outlet of the air guide channel is connected to the vent 111. By connecting the drying module and the vent 111 through the air guide channel, an efficient defoaming gas delivery path can be established between the drying module and the vent 111, ensuring that the circulating air or regenerated air can be accurately delivered to the vent.

[0042] See Figure 1 As shown, the vent 111 in this embodiment is a ventilation channel opened on the side wall of the outer drum 11. Its diameter and number 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.

[0043] In some embodiments, the venting part in this embodiment 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 in this embodiment can also be other devices or structures capable of connecting the interior of the outer cylinder 11 to the internal cavity of the shell.

[0044] See Figure 1 As shown, in some specific embodiments, the air outlet of the air guide channel corresponds to the position of the vent 111 and is spaced apart from the vent 111. The distance between the air outlet of the air guide channel and the vent 111 is 3cm to 5cm. It should be noted that the air outlet of the air guide channel in this embodiment refers to the end opening in the defoaming module used to output defoaming gas. The correspondence between the air outlet of the air guide channel and the vent 111 means that the end opening of the air guide channel and the vent 111 form a specific spatial arrangement. For example, the edge of the air outlet maintains a certain distance from the inlet plane of the vent 111. Setting the distance between the air outlet of the air guide channel and the vent 111 to 3cm to 5cm can ensure that the defoaming gas fully acts on the vent 111 area.

[0045] Specifically, if the distance between the air outlet of the air guide channel and the vent 111 is less than 3cm, it may cause the airflow impact to be too strong and interfere with the air pressure regulation function of the vent 111. If the distance between the air outlet of the air guide channel and the vent 111 is greater than 5cm, it will cause the airflow diffusion to attenuate and weaken the defoaming effect.

[0046] See Figure 1 As shown, in some specific embodiments, the air outlet of the air guide channel in this embodiment is located above the vent 111. It should be noted that "the air outlet of the air guide channel is located above the vent 111" means that the air outlet of the air guide channel is positioned above the vent 111, allowing the defoaming gas to form a downward directional airflow under gravity. Positioning the air outlet of the air guide channel above the vent 111 allows the defoaming gas to cover the vent 111 area downwards under gravity, avoiding airflow scattering or energy loss caused by lateral airflow.

[0047] In some specific embodiments, the air outlet of the air guide channel in this embodiment is located directly above the vent 111. "Directly above the vent 111" means that the air outlet of the air guide channel is positioned vertically above the vent 111, allowing the defoaming gas to form a downward directional airflow under gravity. Positioning the air outlet of the air guide channel directly above the vent 111 allows the defoaming gas to naturally cover the vent 111 area downwards under gravity, avoiding airflow scattering or energy loss caused by lateral airflow. Of course, in other embodiments, the air outlet of the air guide channel in this embodiment can also be located to the side or above the vent 111, or other locations that can deliver the defoaming gas to the vent 111.

[0048] See Figures 2 to 4 As shown, in some specific embodiments, the drum module in this embodiment also includes an inner cylinder 12, which is disposed inside the inner cylinder 12. The drying module includes a molecular sieve assembly 22 and a circulating air generating assembly. The molecular sieve assembly 22 has a circulating air channel. The air inlet of the circulating air generating assembly is connected to the interior of the inner cylinder 12, the air outlet of the circulating air generating assembly is connected to the air inlet of the circulating air channel, and the air outlet of the circulating air channel is connected to the interior of the inner cylinder 12 to form a first closed air path. It should be noted that the molecular sieve component 22 in this embodiment is a device for dehumidification using molecular sieve material. It has an internal circulating air channel for airflow to pass through and for the molecular sieve to contact the humid air to adsorb moisture. The circulating air generating component is an airflow driving device, including a circulating fan 251 and related air duct structures. Its air inlet is connected to the inside of the inner cylinder 12 to draw in humid air, and its air outlet is connected to the air inlet of the circulating air channel to deliver airflow. The first closed air path is composed of the inside of the inner cylinder 12, the circulating air generating component, and the circulating air channel connected in series. The air is driven by the circulating air generating component to circulate in the first closed air path. The molecular sieve component 22 continuously adsorbs moisture in the air, thereby achieving a highly efficient and energy-saving drying operation. At the same time, it avoids the heat energy waste caused by traditional exhaust drying, significantly improves the drying efficiency of the clothing treatment device, and reduces energy consumption. In this embodiment, the drying module constructs a first closed air path through the coordinated operation of the molecular sieve component 22 and the circulating air generator component, allowing hot and humid air to circulate within the first closed air path. The forced convection driven by the circulating air generator component effectively improves the uniformity of drying and avoids the problem of local overheating or insufficient drying inside the inner cylinder 12. The physical adsorption method of the molecular sieve does not require high-temperature heating and can achieve efficient dehumidification under low-temperature conditions, significantly reducing the risk of damage to clothing fibers. The closed-loop system design prevents the leakage of hot and humid air, maintaining a comfortable working environment and avoiding energy waste.

[0049] See Figure 1As shown, the drum module in this embodiment is the core functional component of the clothing handling device. It includes 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 as a stationary container. The inner drum 12 is rotatably disposed inside the outer drum 11 and is used to hold and agitate the clothing. The drum module in this embodiment is responsible for realizing the main functions of loading, washing, and dehydrating the clothing. It should be noted that the outer drum 11 in this embodiment is made of corrosion-resistant materials such as stainless steel, forming a space for holding the washing liquid. A certain gap is maintained between the outer drum 11 and the housing, forming an internal cavity of the housing.

[0050] In some embodiments, the inner cylinder 12 in this embodiment is provided with a circulating air inlet and a circulating air outlet that connect the inside of the inner cylinder 12. The air inlet of the circulating air generator is connected to the inside of the inner cylinder 12 through the circulating air outlet. The air outlet of the circulating air generator is connected to the air inlet of the circulating air channel. The air outlet of the circulating air channel is connected to the inside of the inner cylinder 12 through the circulating air outlet, so as to form a first closed air path.

[0051] Figures 2 to 4 See Figures 2 to 4 As shown, in some specific embodiments, the drying module in this embodiment further includes a heating component 21, which is used to heat the molecular sieve component 22. It should be noted that the heating component 21 in this embodiment refers to a regeneration device specifically designed for the molecular sieve component 22. It uses heating to desorb moisture from the saturated molecular sieve material in the molecular sieve component 22, thereby achieving the regeneration and reuse of the molecular sieve material. Specifically, when the molecular sieve component 22 reaches saturation with adsorbed moisture, the heating component 21 heats the molecular sieve component 22, causing the adsorbed moisture to desorb and release at an appropriate temperature. By adding a heating component 21, the drying module can desorb moisture from the molecular sieve component 22 through periodic heating by the heating component 21, realizing in-situ regeneration of the molecular sieve component 22. This allows the adsorbent material to be reused, significantly reducing maintenance costs. Furthermore, the heating and regeneration process in this embodiment can be carried out automatically during the intervals of the drying operation, ensuring that the molecular sieve component 22 always maintains the best adsorption state and guaranteeing the stability of the drying efficiency. The whole process forms a closed-loop working cycle of adsorption and desorption, enabling the drying module to achieve long-term stable operation without the need to replace the adsorbent material.

[0052] In this process, desorption of water from the molecular sieve material refers to the process of desorbing and releasing adsorbed water from the molecular sieve material through heat energy. Regeneration refers to the process of restoring the molecular sieve material to a dry state and regaining its water absorption capacity through the above desorption treatment. In this embodiment, the drying module realizes the recycling of the molecular sieve component 22 through a heating regeneration mechanism, which not only ensures continuous and efficient drying performance but also avoids the problem of frequent replacement of adsorbent materials.

[0053] In some embodiments, the heating component 21 in this embodiment is a tubular electric heater, including a high-temperature resistant metal shell, a built-in resistance wire, and a temperature sensor. The metal shell is partially embedded in the inner wall of the regeneration air duct, the resistance wire is arranged along the axial direction of the duct, and the temperature sensor adjusts the heating power in real time, forming an integrated heating structure for the air duct. Of course, in other embodiments, the heating component 21 in this embodiment can also use other types of heaters.

[0054] See Figure 2 As shown in some specific embodiments, the first closed air path in this embodiment has a first defoaming gas outlet 271. It should be noted that the first defoaming gas outlet 271 in this embodiment is a branch airflow outlet specifically set in the first closed air path, used to export circulating air to provide defoaming gas. By setting the first defoaming gas outlet 271 to connect the first closed air path and the defoaming module, the circulating air in the first closed air path can be diverted to the defoaming module, and then introduced into the venting section for defoaming. Using the circulating air diverted from the first closed air path as the defoaming gas eliminates the need for additional energy-consuming devices, thus improving the energy efficiency of the clothing treatment device.

[0055] See Figure 2 As shown in some specific embodiments, the first defoaming gas outlet 271 in this embodiment is located between the circulating air generating component and the molecular sieve component 22. It should be noted that in this embodiment, the first defoaming gas outlet being located between the circulating air generating component and the molecular sieve component 22 means that the position of the first defoaming gas outlet is limited to the duct section between the circulating air generating component and the molecular sieve component 22. The circulating air generating component, as the power source of the circulating air, generates airflow that is diverted by the first defoaming gas outlet before entering the molecular sieve component 22. The molecular sieve component 22 is located downstream of the first defoaming gas outlet, ensuring that the main airflow after diversion can still perform normal dehumidification circulation. By setting the first defoaming gas outlet 271 in the duct section between the circulating air generating component and the molecular sieve component 22, the high-speed airflow output by the circulating air generating component is diverted before entering the molecular sieve component 22, ensuring that the defoaming gas obtains the original airflow that has not undergone dehumidification treatment. The defoaming gas with a certain humidity is beneficial for foam elimination. At the same time, the defoaming function is achieved by utilizing the airflow power of the circulating air generating component, eliminating the need for an additional independent fan unit and reducing the energy consumption of the clothing processing device.

[0056] In some embodiments, the first defoaming gas outlet in this embodiment is located between the circulating fan 251 and the molecular sieve assembly 22.

[0057] See Figures 2 to 4As shown, in some embodiments, the drying module in this embodiment further includes a filter component 24. In this embodiment, the filter component 24 is disposed in the first closed air path and is used to filter the circulating air.

[0058] In some embodiments, the filter component 24 in this embodiment adopts a detachable multi-layer composite filter structure. Of course, in other embodiments, the filter component 24 in this embodiment may also adopt other types of filters.

[0059] See Figures 2 to 4 As shown, in some specific embodiments, the drying module in this embodiment further includes a regeneration air generating component and a condenser component 23; the molecular sieve component 22 has a regeneration air channel, the air inlet of the regeneration air generating component is connected to the air outlet of the regeneration air channel, and the air outlet of the regeneration air generating component is connected to the air inlet of the regeneration air channel to form a second closed air path; the condenser component 23 is disposed in the second closed air path. It should be noted that the regeneration air generating component in this embodiment refers to an independent air circulation system specifically used for molecular sieve regeneration treatment, which includes a regeneration fan 261 and related air duct structures. The condenser component 23 refers to a heat exchange device disposed in the second closed air path, used to cool and dehumidify the humid regeneration air. The regeneration air channel is a dedicated airflow channel in the molecular sieve component 22 that is physically isolated from the circulation air channel, through which the regeneration air circulates. The second closed air path is a closed circulation path composed of the regeneration air channel and the regeneration air generating component connected in series. The regeneration air is a specific airflow specifically used to carry desorbed moisture, which circulates in the second closed air path. By forming an independent second closed air path in the drying module, the molecular sieve regeneration process is completely isolated from the main drying cycle, avoiding the backflow of water vapor during the regeneration process and contaminating the main drying circuit. That is, it avoids contaminating the first closed air path and ensures the stability of drying efficiency. At the same time, the forced convection driven by the regeneration air component, combined with the heating component 21, significantly improves the desorption efficiency of the molecular sieve. The condensation component 23 effectively condenses and discharges the water vapor in the regeneration air from the system, achieving efficient separation and discharge of moisture.

[0060] See Figures 2 to 4 As shown, in some embodiments, the molecular sieve assembly 22 in this embodiment adopts a rotary structure, including a rotatable molecular sieve rotor and a drive motor. The molecular sieve rotor is divided into an adsorption zone and a regeneration zone. The adsorption zone is connected to a circulating air channel to adsorb moisture, and the regeneration zone is connected to a regeneration air channel to achieve desorption and regeneration. The drive motor drives the rotor to rotate periodically, so that the molecular sieve material alternates between adsorption and regeneration states. Of course, in other embodiments, the molecular sieve assembly 22 in this embodiment can also adopt a fixed bed structure. In this case, the molecular sieve assembly 22 includes at least two molecular sieve adsorption tanks arranged in parallel and an air duct switching valve. Each adsorption tank is alternately connected to the circulating air duct or the regeneration air duct through the air duct switching valve to achieve an alternating operation mode of one set adsorbing while the other set is regenerating.

[0061] In some embodiments, the condensing assembly 23 in this embodiment employs a finned tube condenser, including a serpentine heat exchange tube, a heat dissipation fin array, and a condensate collection tank. The serpentine heat exchange tube penetrates the regeneration air duct, and the heat dissipation fins are arranged at intervals outside the tube, forming counter-current heat exchange with the regeneration air. The condensate collection tank is equipped with an inclined guide surface or a drain pump for discharging the collected condensate into the regeneration air duct. Of course, in other embodiments, the condensing assembly 23 in this embodiment can also employ other types of condensers.

[0062] See Figure 3 As shown in some specific embodiments, the second closed air path in this embodiment has a second defoaming gas outlet 272, and the drying module also includes a heating component 21, which can heat the gas in the second closed air path. It should be noted that the second defoaming gas outlet in this embodiment is a branch airflow outlet specially set in the second closed air path, used to export the regenerated air heated by the heating component 21 to form defoaming gas. By setting the second defoaming gas outlet 272 to connect the second closed air path and the defoaming module, the regenerated air in the second closed air path can be diverted to the defoaming module, and then introduced into the venting section for defoaming. Using the regenerated air diverted from the second closed air path as the defoaming gas eliminates the need for additional energy-consuming devices, which is beneficial to improving the energy efficiency of the clothing treatment device.

[0063] In some embodiments, the heating component 21 in this embodiment is at least partially disposed in the regeneration air duct, enabling the heating component 21 to directly heat the regeneration air. The drying module in this embodiment utilizes the existing airflow path within the regeneration air duct, allowing the heating component 21 to directly heat the regeneration air, effectively improving heat conversion efficiency and reducing energy loss. Simultaneously, through precise temperature control and heating of the regeneration air, defoaming gas with defoaming function is generated, achieving synergistic operation of regeneration and defoaming. The defoaming gas is exited from the drying module through a specially designed second defoaming gas outlet, forming an independent airflow channel, ensuring that the defoaming function does not affect the normal operation of the regeneration cycle. No additional heating device is required, simplifying the drying module structure, reducing manufacturing costs, and simultaneously achieving multiple uses of energy, significantly improving the overall performance of the garment processing device.

[0064] See Figure 3As shown in some specific embodiments, the second defoaming gas outlet 272 in this embodiment is located between the regenerating air generating component and the condensing component 23. It should be noted that in this embodiment, the second defoaming gas outlet being located between the regenerating air generating component and the condensing component 23 means that the position of the second defoaming gas outlet is limited to the duct section between the regenerating air generating component and the condensing component 23. The airflow generated by the regenerating air generating component is diverted by the second defoaming gas outlet before entering the condensing component 23, ensuring that the defoaming gas obtains a high-temperature airflow that has not undergone condensation treatment. The condensing component 23 is located downstream of the second defoaming gas outlet, ensuring that the moisture condensation function of the second closed airflow path is not affected. By setting the second defoaming gas outlet in the duct position between the regenerating air generating component and the condensing component 23, the high-speed airflow output by the regenerating air generating component is diverted before passing through the condensing component 23, ensuring that the defoaming gas obtains a high-temperature airflow that has not undergone condensation treatment. The defoaming gas with a certain humidity is beneficial for foam elimination. At the same time, the defoaming function is achieved using the airflow power of the regenerating air generating component, eliminating the need for an additional independent fan unit and reducing the energy consumption of the clothing processing device.

[0065] See Figure 1 As shown, in some specific embodiments, the defoaming module in this embodiment includes a defoaming valve 31 and an air guide duct 32. An air guide channel is formed inside the air guide duct 32. The air inlet end of the defoaming valve 31 is connected to the drying module, and the air outlet end of the defoaming valve 31 is connected to the air inlet end of the air guide channel. The defoaming valve 31 has an open state that connects the drying module to the air inlet end of the air guide channel, and a closed state that isolates the drying module from the air inlet end of the air guide channel. It should be noted that the defoaming valve 31 in this embodiment is an airflow control device, which adopts electromagnetic drive or mechanical transmission and has a bidirectional on / off function. Its air inlet end is connected to the drying module, and its air outlet end is connected to the air guide duct 32. The airflow is opened by the open state and the airflow is isolated by the closed state. The air guide duct 32 is a pipe structure with a specific flow channel cross-section. The air guide channel formed inside it is used to directionally transport defoaming gas to the vent 111 area. The defoaming function is activated on demand by controlling the opening and closing of the defoaming valve 31.

[0066] See Figure 2 As shown, in some embodiments, the air inlet of the defoaming valve 31 in this embodiment includes a first air inlet interface, which is connected to the first defoaming gas outlet 271. When the defoaming valve 31 is in the open state, the first defoaming gas outlet 271 is connected to the air inlet of the air guide channel. When the defoaming valve 31 is in the closed state, the first defoaming gas outlet 271 is isolated from the air inlet of the air guide channel.

[0067] See Figure 3As shown, in some embodiments, the air inlet of the defoaming valve 31 in this embodiment includes a second air inlet interface, which is connected to the second defoaming gas outlet 272. When the defoaming valve 31 is in the open state, the second defoaming gas outlet 272 is connected to the air inlet of the air guide channel. When the defoaming valve 31 is in the closed state, the second defoaming gas outlet 272 is isolated from the air inlet of the air guide channel.

[0068] See Figure 4 As shown, in some embodiments, the air inlet of the defoaming valve 31 in this embodiment includes a first air inlet structure and a second air inlet interface. The first air inlet interface is connected to the first defoaming gas outlet 271, and the second air inlet interface is connected to the second defoaming gas outlet 272. When the defoaming valve 31 is in the open state, at least one of the first defoaming gas outlet 271 and the second defoaming gas outlet 272 is connected to the air inlet of the air guide channel. When the defoaming valve 31 is in the closed state, the first defoaming gas outlet 271 and the second defoaming gas outlet 272 are isolated from the air inlet of the air guide channel.

[0069] In some specific embodiments, the garment processing device in this embodiment further includes a control module, which is electrically connected to the defoaming module and the drying module, and is used to control the operation of the defoaming module and the drying module. 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 system operation, which forms a control loop with the defoaming module and the drying module through electrical connection. The control module precisely regulates the start / stop and working intensity of the defoaming module, as well as the gas delivery timing and flow parameters of the drying module, through preset programs or real-time detection signals, to achieve coordinated operation of the two functional modules. 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, improving 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.

[0070] 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 preset 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 the foam height 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 receive the defoaming signal output by the foam detection module and control the defoaming module to operate according to the signal, thereby promptly eliminating the foam.

[0071] 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.

[0072] 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.

[0073] 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.

[0074] In some specific embodiments, when the clothing processing device provided in this embodiment has a water level sensor, if the foam detection module detects that the foam height in the outer drum 11 reaches a preset safety threshold when washing clothes, it will generate and output a high foam signal to the control module. The control module will then sequentially open the defoaming valve 31 and the drying module. At this time, the defoaming module will deliver defoaming gas to the vent 111 of the outer drum 11 to eliminate the foam in the vent 111 of the outer drum 11 and inside the outer drum 11. When the control module detects that the defoaming signal has disappeared, the control module will sequentially close the drying module and the defoaming valve 31.

[0075] It should be noted that when the control module turns on the drying module, it first turns on the regeneration fan 261 and the circulating fan 251, and then turns on the drive motors of the heating component 21 and the molecular sieve component 22 5 to 10 seconds after the regeneration fan 261 and the circulating fan 251 are turned on. By turning on the regeneration fan 261 and the circulating fan 251 5 to 10 seconds in advance, the risk of local overheating caused by starting the heating component 21 in a windless state can be avoided.

[0076] In some specific embodiments, when the clothing processing device provided in this embodiment is not equipped with a water level sensor, when the clothing processing device provided in this embodiment is washing clothes, the control module detects whether the clothing processing device is in the main washing stage. If it is in the main washing stage, it will sequentially open the defoaming valve 31 and the drying module. At this time, the defoaming module delivers defoaming gas to the vent 111 of the outer drum 11 to eliminate the foam in the vent 111 of the outer drum 11 and inside the outer drum 11. When the control module detects that the main washing stage is over, the control module will sequentially close the drying module and the defoaming valve 31.

[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 shell 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 deliver defoaming gas to the venting section. At this time, the defoaming gas can contact the foam in the venting section, and can also contact the foam inside the outer drum through the venting section. When the defoaming gas is circulating air, the defoaming gas eliminates the foam in the venting section and inside the outer drum through airflow impact. When the defoaming gas is regenerated air, the defoaming gas quickly decomposes and eliminates the foam in the venting section and inside the outer drum through the dual action of hot air heating and airflow impact, preventing foam from overflowing from the venting section and contaminating the internal cavity of the shell. By instantly dissolving the foam in the venting section and inside the outer drum, the overflow phenomenon caused by foam accumulation can be avoided to a certain extent, improving the reliability of the clothing processing device.
