Description

Technical Field

[0001] This application relates to the field of household appliance technology, and in particular to a clothing processing device and an automatic drying drum control method. Background Technology

[0002] The field of home appliance technology encompasses a wide range of product categories, including but not limited to refrigerators, washing machines, air conditioners, microwave ovens, dishwashers, and vacuum cleaners. The technological development trends for these products primarily focus on intelligentization, energy conservation and environmental protection, optimized user experience, and the application of new materials. Optimized user experience is achieved through design innovation and functional enhancement to meet consumers' demands for health, convenience, and personalization.

[0003] As an important household appliance, the laundry drying unit greatly reduces people's housework burden. With the improvement of living standards, users' demands for its functions are increasing. After washing clothes, the washing machine retains moisture, which may lead to mold and odors over time. Therefore, users generally leave the washing machine door open to dry clothes, and some even buy stands to ensure the door can be opened. However, this not only adds extra work and takes up space, but also affects the reliability of the washing machine door hinges. Summary of the Invention

[0004] This application discloses a clothing processing device and an automatic drying drum control method, which can use heated drying air to dry the moisture in the outer and inner drums. The humid drying air can be discharged from the air outlet on the front inspection cover. On the one hand, the front air outlet makes it easier for users to perceive the drying effect of the drying air, and avoids obstruction of the air outlet at the rear of the cabinet. On the other hand, it eliminates the need to open an additional air outlet on the cabinet, increases the structural strength of the cabinet, and improves the aesthetics of the clothing processing device.

[0005] To achieve the above objectives, in a first aspect, some embodiments of this application provide a garment processing device, comprising: a housing, the housing including: a front panel having a drain pump access port; a back panel disposed opposite to the front panel along the front-rear direction of the housing, the back panel having an air inlet; an outer tube disposed within the housing; an inner tube disposed within the outer tube and rotatable relative to the outer tube; and an air inlet duct disposed within the housing, one end of the air inlet duct being connected to the air inlet, the other end being connected to the air outlet. The device is connected to the outer cylinder; a heating element is disposed in the air inlet duct to heat the drying air flowing through the air inlet duct; an inspection cover is disposed on the drain pump inspection port, and the inspection cover is provided with an air outlet; an air outlet duct is disposed in the housing, one end of the air outlet duct is connectable to the outer cylinder, and the other end is connected to the air outlet; a fan assembly is connected to the air inlet duct and / or the air outlet duct to drive the drying air to flow sequentially through the air inlet duct, the outer cylinder and the air outlet duct.

[0006] In this way, by integrating the drying air outlet with the front panel drain pump access port, the drying air is discharged from the front through the air outlet on the access cover. This allows for automatic drying of both the outer and inner drums, removing residual moisture, while the drying air is discharged from the front of the unit, making it easy for users to visually perceive the drying process and results. Simultaneously, it avoids the situation where the air outlet is located on the rear of the unit, which can easily lead to obstructed ventilation when the washing machine is placed against a wall or recessed installation, effectively ensuring smooth ventilation and improving drying reliability and efficiency.

[0007] Furthermore, this structure directly utilizes the existing drain pump access port on the front panel as an exhaust channel, eliminating the need for additional independent exhaust vents in other locations within the cabinet. This reduces the number of openings in the cabinet, helps maintain the overall structural strength and rigidity, and lowers the risks of sealing, waterproofing, and structural weakness caused by multiple openings. At the same time, the absence of extra exhaust openings on the overall exterior contributes to a cleaner and more unified appearance, significantly enhancing the aesthetics and overall integrity of the garment processing device.

[0008] Furthermore, the layout integrating the front drain pump inspection port with the air outlet simplifies the overall air duct structure design, eliminating the need for a lengthened and bent independent air outlet duct for the rear exhaust. This optimizes the internal space layout, saves space at the rear of the outer cylinder, improves internal space utilization, and reduces the complexity of air duct processing and assembly. It also facilitates manufacturing and subsequent maintenance, achieving integrated drying, maintenance, and aesthetic design. The air inlet is located at the rear of the cabinet, and the air outlet at the front, further preventing the backflow of hot, humid drying air to the air inlet.

[0009] As an optional implementation, a drain pump bracket is provided, which covers the side of the drain pump inspection port facing the rear panel. An air outlet cavity is formed between the drain pump bracket and the inspection cover. The drain pump bracket has a first opening, and the outlet of the air outlet duct communicates with the air outlet cavity through the first opening. The drain pump bracket also has a second opening. A drain pump is provided at the bottom of the housing, and the drain pump plug of the drain pump is provided in the second opening.

[0010] This embodiment utilizes the existing drain pump bracket structure of the washing machine, which, in conjunction with the inspection cover, forms an air outlet chamber, thus reusing the drying air outlet function with the existing structure. This air outlet chamber, serving as a transition cavity between the air outlet duct and the air outlet hole of the inspection cover, can stably receive the drying air from the air outlet duct, ensuring that the airflow is evenly and smoothly guided to the air outlet hole for discharge. This improves the airflow efficiency of the duct, reduces wind resistance and air leakage, and enhances the operational stability of the drying system.

[0011] The drain pump bracket has a first opening and a second opening, integrating the three functions of drying air outlet, drain pump assembly, and maintenance port sealing into a single structure. The first opening connects the air outlet duct and the air outlet chamber, while the second opening is used to assemble the drain pump plug. Without changing the original drainage and maintenance functions, the duct structure is built-in and integrated, eliminating the need for additional independent duct adapters, simplifying the internal layout, and improving space utilization.

[0012] This solution requires no major modifications to the existing housing, front panel, and drainage system. Front air outlet can be achieved simply through structural adaptation, which helps reduce design and manufacturing costs and improves production and assembly efficiency. At the same time, utilizing the existing drainage pump bracket to form the air outlet cavity ensures the overall structural strength of the machine while maintaining a simple appearance. It also achieves compatibility between the drying function and conventional structures, resulting in greater reliability and practicality.

[0013] As an optional implementation, the drain pump bracket includes a bottom wall and a side wall surrounding the bottom wall. A third opening is formed on the side of the drain pump bracket facing the front plate, and the third opening is corresponding to the drain pump access port. A second opening is provided on the bottom wall and is corresponding to the drain pump access port along the front-rear direction of the housing. The first opening is provided on the side wall.

[0014] Thus, the second opening is located on the bottom wall and corresponds to the drain pump inspection port in the front-to-back direction. This allows for the docking of the drain pump plug and the drain pump inspection port without changing the conventional assembly position and maintenance path of the drain pump. This ensures that the original functions such as drainage, cleaning, and maintenance are not affected, and achieves reasonable avoidance and compatibility between the drying air duct and the drainage maintenance structure. The first opening is located on the side wall, allowing for lateral communication between the air outlet duct and the air outlet cavity. This avoids insufficient structural strength of the drain pump support due to the first and second openings being too close, which would affect the maintenance of the drain pump.

[0015] This layout makes full use of the limited space at the bottom of the enclosure, allowing the air outlet, drainage pump installation, and maintenance passage to be arranged in an orderly manner within the same structure, further improving space utilization and structural compactness. It eliminates the need for additional transfer structures, simplifying the assembly process while enhancing the overall reliability and structural stability of the machine.

[0016] As an optional implementation, the fan assembly includes: a first fan disposed in the air inlet duct to drive air outside the housing into the air inlet duct through the air inlet; and a second fan disposed in the air outlet duct to drive the drying air inside the outer cylinder out through the air outlet duct.

[0017] Thus, the first fan is responsible for actively drawing in external air into the air inlet duct and pushing it into the heating element and outer cylinder, while the second fan is responsible for drawing out the humid and hot drying air from the outer cylinder and discharging it to the front. The two fans working together can increase the drying airflow and circulation speed, prevent airflow from stagnating or flowing back inside the cylinder, and effectively improve drying efficiency and drying uniformity.

[0018] By employing separate and independently controlled inlet and outlet fans, the airflow of the drying system can be matched, avoiding problems such as uneven duct pressure, high air resistance, and high noise caused by a single fan relying solely on extraction or blowing. The two fans are respectively located on the inlet and outlet sides, and their respective speeds and operating times can be flexibly adjusted according to drying needs. This ensures that heated air can smoothly enter the drum while humid air is quickly discharged, improving the overall drying performance and operational stability of the machine.

[0019] As an optional implementation, the first fan includes an axial fan, the axis of rotation of which extends along the front-rear direction of the housing.

[0020] In this way, the air intake duct extends along the front-to-back direction, and the rotation axis of the axial fan extends along the front-to-back direction of the enclosure. This saves space while fully utilizing the structural advantages of the axial fan and improving the air delivery performance on the intake side. The axial fan adopts an axial airflow structure, with the airflow direction consistent with the fan's rotation axis. This is adapted to the front-to-back direction of the rear panel air intake and air intake duct, allowing external air to smoothly enter the duct, reducing airflow deflection and wind resistance, and ensuring smooth and stable air delivery.

[0021] While delivering the same airflow, axial fans are smaller and lighter than other types of fans, effectively reducing the space occupied in the air intake duct, simplifying the duct structure design, improving the utilization of internal space, and reducing the overall weight of the machine, thus reducing the load on the installation and support structures. The lightweight and compact structure of axial fans allows for more flexible installation within the limited space inside the washing machine, facilitating proper avoidance of interference with heating elements, duct walls, and other structures, thus reducing assembly difficulty.

[0022] The axial fan is suitable for high-flow, low-pressure air intake conditions, enabling a larger air intake volume under lower air pressure requirements. It quickly introduces and delivers external air to the heating elements and outer cylinder, meeting the air intake volume requirements of the drying system. This design improves air intake efficiency and optimizes the structural layout, making the whole machine more compact, more reliable in operation, and easier to assemble while achieving efficient drying.

[0023] As an optional implementation, the second fan includes: a centrifugal volute disposed below the outer cylinder, the centrifugal volute including an axial air inlet and a radial air outlet, the axial air inlet communicating with the outlet of the air outlet duct, and the radial air outlet communicating with the air outlet hole; and a centrifugal fan disposed inside the centrifugal volute, the rotation axis of the centrifugal fan extending along the front-rear direction of the housing.

[0024] In this way, the centrifugal volute is arranged below the outer cylinder and in the space between the outer cylinder and the front plate. This allows for a compact layout of the entire machine structure while making full use of the unused space at the bottom of the chamber, effectively saving installation space and improving the utilization rate of the internal space of the chamber.

[0025] The axial dimension of the centrifugal volute is usually smaller than the radial dimension. The axis of the centrifugal volute is arranged in the front-to-back direction and is adapted to the position of the air outlet duct and air outlet cavity. Without increasing the width, thickness and height of the whole machine, the drying air in the air outlet duct is drawn into the air outlet cavity of the drain pump bracket located on the side of the outer cylinder in the front-to-back direction of the box, so as to achieve a combination of space utilization and functional realization.

[0026] Centrifugal fans are characterized by high air pressure and strong resistance, ensuring that the drying air absorbed by the outer drum is stably extracted and smoothly discharged. This avoids problems such as poor ventilation and airflow backflow caused by high duct resistance, thus guaranteeing the continuity and efficiency of the drying cycle. At the same time, centrifugal fans offer high operational stability and low noise, maintaining stable operation even under high ventilation demands, reducing overall machine noise and improving the user experience of the garment processing device.

[0027] As an optional implementation, the outer cylinder is provided with a drying air inlet and a drying air outlet. The drying air inlet is connected to the outlet of the air inlet duct, and the drying air outlet is connected to the inlet of the air outlet duct. The drying air outlet is located near the bottom of the housing relative to the drying air inlet, and the drying air outlet and the drying air inlet are arranged radially opposite to each other along the outer cylinder.

[0028] In this way, after the drying air enters the outer cylinder from one side inlet, it can pass through the inner cylinder laterally and flow to the radially opposite outlet, fully penetrating the internal space of the cylinder, avoiding problems such as local airflow short circuits and drying dead zones, and ensuring that both the inner and outer cylinders can fully exchange heat with the high-temperature drying air.

[0029] Placing the drying air outlet near the bottom of the chamber allows the air to flow gradually from top to bottom throughout the entire cavity, effectively removing residual moisture that tends to accumulate at the bottom of the inner and outer cylinders. This improves the self-drying effect of the cylinder and reduces problems such as odors and mold caused by moisture retention. Furthermore, the radially opposite layout of the drying air inlet and outlet extends the effective residence time of the air within the cylinder, increasing heat utilization and achieving better drying results with the same airflow and heating power.

[0030] This arrangement is fully adapted to the drum structure of the drum-type garment processing device. Without changing the overall structure of the outer drum or taking up additional internal space, it optimizes the drying airflow path and improves the smoothness of airflow. This ensures stable entry and exit of drying air and improves the overall drying performance and operational reliability of the machine, achieving a dual optimization of structural layout and drying effect.

[0031] As an optional implementation, the garment processing device further includes: an air outlet pipe, wherein the air outlet pipe forms the air outlet duct, and the air outlet pipe is a flexible connecting pipe.

[0032] In this way, the flexible tube can be fully utilized to make flexible arrangements of the exhaust path in the limited and complex space inside the washing machine, effectively avoiding interference areas between rigid components such as the outer drum, drain pump, and cabinet, and improving the adaptability and space utilization of the air duct layout.

[0033] Flexible connecting pipes can freely adjust their direction and curvature according to the actual assembly environment, without having to strictly follow a fixed angle or straight line arrangement. They can make full use of scattered and irregular idle spaces such as the bottom of the box and the sides of the cylinder, avoiding the additional occupation of effective space due to the fixed size and position of rigid pipes. This results in a more compact overall structure, which is conducive to reducing the overall size of the machine or optimizing the internal space allocation.

[0034] Meanwhile, flexible connecting pipes have a higher fault tolerance rate and are easier to install during assembly. They can adapt to positional deviations between components and do not require a large assembly space for rigid pipe connections. This further saves installation space and simplifies assembly procedures. Under the premise of ensuring smooth airflow during drying, they achieve a dual improvement in space utilization and assembly convenience.

[0035] As an optional implementation, the garment handling device further includes: an air outlet pipe, in which the air outlet channel is formed; and a switch valve disposed in the air outlet pipe to open or close the air outlet pipe. The garment processing device further includes a humidity sensor disposed inside the air outlet duct, the humidity sensor being configured to detect the humidity of the drying air passing through the air outlet duct.

[0036] In this way, the switching valve can controllably open or close the air outlet duct according to the start and stop of the drying mode. In non-drying conditions, it reliably closes the duct, effectively preventing water vapor, foam, or washing water from flowing back into the duct during washing and spin-drying. This prevents dirt accumulation, odors, and moisture damage to internal components, ensuring clean and stable operation of the entire machine. The humidity sensor can detect the humidity of the drying air flowing through the air outlet duct in real time, providing feedback on the dryness level inside the outer drum. This provides a true and accurate basis for drying control, enabling automatic identification of the drying degree. Combined with the switching valve, heating element, and fan assembly, a closed-loop automatic control system can be formed. Drying is stopped promptly when the clothes or drum reach the preset dryness level, avoiding over-drying which can damage clothes and waste energy, and also avoiding under-drying which can leave residual moisture, improving the accuracy and consistency of the drying effect.

[0037] Secondly, this application discloses an automatic drying drum control method for the clothing processing device described in the first aspect. The clothing processing device includes an air inlet duct, an air outlet duct, a heating element, a fan assembly, a switching valve, and a humidity sensor. The heating element is disposed in the air inlet duct, the fan assembly is connected to the air inlet duct and / or the air outlet duct, the humidity sensor is used to detect the humidity inside the outer drum, and the switching valve is disposed in the air outlet duct. The automatic drying drum control method includes: Select to enter automatic drum drying mode; Control the opening of the switching valve, the heating element, and the fan assembly; The humidity sensor detects whether the humidity inside the outer cylinder has decreased to a preset humidity level; If the humidity is less than or equal to the preset humidity, the switching valve, the heating element, and the fan assembly are controlled to shut down.

[0038] Thus, this method uses the real-time humidity of the drying air detected by a humidity sensor as the control basis, which can identify the drying status of the outer and inner drums. When the humidity drops to the preset humidity, the switching valve, heating element, and fan assembly are automatically shut off. This avoids residual moisture and odors in the drum due to insufficient drying, while also preventing energy waste and component overheating caused by over-drying, achieving an optimal balance between drying effect and energy consumption control. The control logic is simple and reliable. When used in the garment processing device described in the first aspect, it is highly compatible with the structural design of front air outlet, integrated air duct, and dual fan drive. While achieving automatic drum drying and maintaining the dryness and hygiene of the entire machine, it does not increase structural complexity or control costs, further improving the user experience, operational stability, and service life of the garment processing device.

[0039] Compared with the prior art, the beneficial effects of this application are at least as follows: The clothing processing device and automatic drying drum control method disclosed in this application embodiment heat the airflow in the air inlet duct with a heating element. The heated drying air can dry the moisture in the outer drum and the inner drum. The humid drying air can be discharged from the air outlet on the front inspection cover. On the one hand, the front air outlet makes it easy for the user to perceive the drying effect of the drying air, and avoids the air outlet obstruction on the rear side of the cabinet. On the other hand, there is no need to open an additional air outlet on the cabinet, which increases the structural strength of the cabinet and improves the aesthetics of the clothing processing device.

Detailed Implementation

[0043] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0044] The directional or positional terms used in this application, such as "upper," "lower," "inner," and "outer," are based on the directions shown in the accompanying drawings and are used only for descriptive purposes, not to limit the actual location or structure. Some terms may have other meanings in different contexts, and those skilled in the art should understand them according to the specific context.

[0045] The terms "installation," "setup," and "connection," etc., should be interpreted broadly to include, but are not limited to, fixed or detachable, mechanical or electrical, direct or indirect connection methods. The terms "first," "second," etc., are used only to distinguish objects and do not indicate importance or order. Unless otherwise stated, "multiple" refers to two or more.

[0046] The field of home appliance technology encompasses a wide range of product categories, including but not limited to refrigerators, washing machines, air conditioners, microwave ovens, dishwashers, and vacuum cleaners. The technological development trends for these products primarily focus on intelligentization, energy conservation and environmental protection, optimized user experience, and the application of new materials. Optimized user experience is achieved through design innovation and functional enhancement to meet consumers' demands for health, convenience, and personalization.

[0047] As an important household appliance, the laundry drying unit greatly reduces people's housework burden. With the improvement of living standards, users' demands for its functions are increasing. After washing clothes, the washing machine retains moisture, which may lead to mold and odors over time. Therefore, users generally leave the washing machine door open to dry clothes, and some even buy stands to ensure the door can be opened. However, this not only adds extra work and takes up space, but also affects the reliability of the washing machine door hinges.

[0048] Based on this, this application discloses a clothing processing device and an automatic drying drum control method, which can use heated drying air to dry the moisture in the outer drum and the inner drum. The humid drying air can be discharged from the air outlet on the front inspection cover. On the one hand, the front air outlet makes it easier for users to perceive the drying effect of the drying air, and avoids obstruction of the air outlet at the rear of the cabinet. On the other hand, there is no need to open an additional air outlet on the cabinet, which increases the structural strength of the cabinet and improves the aesthetics of the clothing processing device.

[0049] The present technical solution will be further described below with reference to the embodiments and accompanying drawings.

[0050] Please see Figures 1 to 2 , Figure 1 This is a schematic diagram of the clothing processing device 100 disclosed in the embodiments of this application from a first-view perspective. Figure 2 This is a second-view structural schematic diagram of the garment processing device 100 disclosed in this application embodiment. The garment processing device 100 includes a housing 1, which serves as the external structure of the garment processing device 100. The housing 1 is typically made of metal or plastic and is used to protect the internal components of the garment processing device 100 and provide stable support. The housing 1 is designed with durability, heat dissipation, noise control, safety, and maintainability in mind. The interior of the housing 1 is designed around a roller to house and protect the roller and other internal structures.

[0051] In some embodiments, the housing 1 includes a front panel 11 and a rear panel 12. The front panel 11 is located at the front of the housing 1 and is used to provide an operation panel, a door, and a drain pump maintenance port 11a, etc. The drain pump maintenance port 11a provides an operating passage for the maintenance and repair of the drain pump. The rear panel 12 is located at the rear of the housing 1 and is arranged opposite to the front panel 11 in the front-rear direction of the housing 1. The rear panel 12 is provided with an air inlet 12a.

[0052] The housing 1 also includes an outer drum 2 and an inner drum 3. The inner drum 3 is located inside the outer drum 2 and can rotate relative to the outer drum 2. It is used to hold clothes and tumble wash the clothes by rotating them. The inner drum 3 has multiple through holes so that the inner drum 3 cavity communicates with the inner cavity of the outer drum 2.

[0053] In some embodiments, combined with Figures 3 to 6 , Figure 3 This is a schematic diagram of the clothing processing device 100 disclosed in this application, omitting the casing 1. Figure 4 for Figure 3 Top view, Figure 5 for Figure 4 Sectional view at point AA. Figure 6 This is an exploded view of the air inlet pipe 4, heating element 41, and first fan 71 disclosed in the embodiments of this application. The clothing processing device 100 also includes an air inlet pipe 4 and a heating element 41. The air inlet pipe 4 is disposed inside the housing 1, and an air inlet duct 4a is formed inside the air inlet pipe 4. One end of the air inlet duct 4a is connected to the air inlet 12a, and the other end is connected to the outer cylinder 2. The heating element 41 is disposed inside the air inlet duct 4a to heat the drying air flowing through the air inlet duct 4a.

[0054] The heating element 41 can be a heating tube or a heating wire. The heating tube is usually made of a metal tube (such as a stainless steel tube) wrapped with a resistance wire. The tube is filled with an insulating and heat-conducting material (such as magnesium oxide powder). When energized, the resistance wire heats up and transfers the heat to the drying air flowing through the metal tube. The heating element 41 can also be a heating plate, which is composed of a metal plate (such as aluminum or copper) and a built-in resistive element, and is in the form of a plate or plate structure. This embodiment does not limit this.

[0055] Combination Figure 1 , Figure 3 and Figure 6 The garment processing device 100 also includes an inspection cover 5, an air outlet duct 6a, and a fan assembly 7. The inspection cover 5 is located on the drain pump inspection port 11a, covering the drain pump inspection port 11a to ensure the front of the housing 1 is sealed and the appearance is intact. When the user needs to repair the drain pump, the drain pump can be repaired by opening the inspection cover 5. The inspection cover 5 is provided with an air outlet 5a, and the air outlet duct 6a is located inside the housing 1. One end of the air outlet duct 6a can be connected to the outer cylinder 2, and the other end is connected to the air outlet 5a on the inspection cover 5, so that the air outlet duct 6a can communicate with the indoor space through the air outlet 5a to discharge the hot and humid drying air from the housing 1. The fan assembly 7 can be connected only to the air inlet duct 4a, or only to the air outlet duct 6a, or simultaneously to both the air inlet duct 4a and the air outlet duct 6a, so as to drive the drying air from the air inlet 12a into the air inlet duct 4a, and after being heated, it enters the outer cylinder 2 and the inner cylinder 3, and finally exits from the air outlet duct 6a through the air outlet hole 5a on the inspection cover 5.

[0056] Thus, by integrating the drying air outlet with the drain pump access port 11a on the front panel 11, the drying air is discharged from the front through the air outlet 5a on the access cover 5. This allows for automatic drying of the outer drum 2 and inner drum 3, removing residual moisture, while the drying air is discharged from the front of the cabinet 1, enabling users to intuitively perceive the drying process and effect. Simultaneously, it avoids the situation where the air outlet is located on the rear of the cabinet 1, which can easily lead to obstructed ventilation when the washing machine is placed against a wall or embedded in the wall, effectively ensuring smooth ventilation and improving drying reliability and efficiency.

[0057] Furthermore, this structure directly utilizes the existing drain pump access port 11a on the front panel 11 as an exhaust channel, eliminating the need for additional independent exhaust vents in other locations on the housing 1. This reduces the number of openings on the housing 1, which helps maintain the overall structural strength and rigidity of the housing 1 and reduces the risks of sealing, waterproofing, and structural weakness caused by multiple openings. At the same time, the absence of extra exhaust openings on the overall exterior surface results in a simpler and more unified appearance, significantly improving the aesthetics and integrity of the clothing handling device 100.

[0058] Furthermore, the layout of integrating the front drain pump inspection port 11a with the air outlet simplifies the overall air duct structure design. It eliminates the need for an extended and bent independent air outlet duct for the rear exhaust, optimizing the internal space layout of the housing 1, saving space behind the outer cylinder 2, improving internal space utilization, and reducing the complexity of air duct processing and assembly. This facilitates manufacturing and subsequent maintenance, achieving integrated drying, maintenance, and aesthetic structure. The air inlet 12a is located at the rear of the housing 1, and the air outlet is located at the front of the housing 1, further preventing the backflow of hot and humid drying air to the air inlet 12a.

[0059] It should be noted that the drying air flows in the air inlet duct 4a, inside the outer drum 2, and in the air outlet duct 6a. It can not only dry the residual moisture in the outer drum 2 and the inner drum 3, but also dry the clothes washed in the inner drum 3.

[0060] It should also be noted that the fan assembly 7 may include one fan, two fans or more fans, and may be connected only to the air inlet duct 4a, or only to the air outlet duct 6a, or may be connected to both the air inlet duct 4a and the air outlet duct 6a respectively, without limitation here.

[0061] In some embodiments, combined with Figure 3 and Figure 7 , Figure 7The present invention is a schematic diagram of the structure of the drain pump bracket 8 disclosed in the embodiments of this application. The clothing processing device 100 also includes a drain pump bracket 8 and a drain pump (not shown in the figure). The drain pump bracket 8 covers the side of the drain pump inspection port 11a facing the back panel 12. An air outlet chamber 8a is formed between the drain pump bracket 8 and the inspection cover 5. The drain pump bracket 8 is provided with a first opening 8b. The outlet of the air outlet duct 6a is connected to the air outlet chamber 8a through the first opening 8b. The drain pump bracket 8 is also provided with a second opening 8c. The drain pump is located at the bottom of the housing 1, and the drain pump plug of the drain pump is located in the second opening 8c.

[0062] The drain pump is used to discharge the washing water after washing and spin-drying from the outer drum 2 to the outside of the machine body. The drain pump bracket 8 is set at the bottom of the box 1 to install, support and position the drain pump. It is also covered inside the drain pump inspection port 11a, providing a structural basis for the disassembly, assembly and cleaning of the drain pump. It is a conventional structure for the washing machine to realize the drainage function and maintenance.

[0063] The drain pump plug is a removable component located outside the drain pump's filter chamber. It is typically a screw cap or plug and is used to seal the drain pump's drain access port. During normal washing machine operation, the drain pump plug reliably seals the drain access port, preventing wash water leakage and ensuring stable internal pressure for proper drainage. If foreign objects such as lint, coins, or buttons enter the drain pump, causing blockage or jamming, users or repair personnel can directly unscrew or remove the drain pump plug to quickly clean the filter chamber and pump body without disassembling the entire machine, enabling convenient inspection and maintenance.

[0064] Thus, this embodiment utilizes the existing drain pump bracket 8 structure of the washing machine, which, together with the inspection cover 5, forms an air outlet cavity 8a, achieving the reuse of the drying air outlet function and the existing structure. This air outlet cavity 8a serves as a transition cavity between the air outlet duct 6a and the air outlet hole 5a of the inspection cover 5, stably receiving the drying air from the air outlet duct 6a, ensuring that the airflow is evenly and smoothly guided to the air outlet hole 5a for discharge, improving the airflow efficiency, reducing wind resistance and air leakage, and enhancing the operational stability of the drying system.

[0065] The drain pump bracket 8 is equipped with a first opening 8b and a second opening 8c, integrating the three functions of drying air outlet, drain pump assembly, and maintenance port sealing into a single structure. The first opening 8b connects the air outlet duct 6a and the air outlet cavity 8a, while the second opening 8c is used to assemble the drain pump plug. Without altering the original drainage and maintenance functions, the duct structure is internally integrated, eliminating the need for additional independent duct adapters, simplifying the internal layout, and improving space utilization.

[0066] This solution requires no major modifications to the existing housing 1, front panel 11, and drainage system. Front air outlet can be achieved simply through structural adaptation, which helps reduce design and manufacturing costs and improve production and assembly efficiency. At the same time, the air outlet cavity 8a is formed by utilizing the existing drainage pump bracket 8, which ensures the structural strength of the whole machine while maintaining a simple appearance. It also achieves compatibility between the drying function and conventional structures, resulting in greater reliability and practicality.

[0067] The first opening 8b and the second opening 8c can be set at any position on the drainage pump bracket 8 as needed, and no limitation is made here.

[0068] In some embodiments, combined with Figure 7 The drain pump bracket 8 includes a bottom wall 81 and a side wall 82 surrounding the bottom wall 81. A third opening 8d is formed on the side of the drain pump bracket 8 facing the front plate 11. The third opening 8d is corresponding to the drain pump inspection port 11a. A second opening 8c is provided on the bottom wall 81 and is corresponding to the drain pump inspection port 11a in the front-rear direction of the housing 1. A first opening 8b is provided on the side wall 82.

[0069] The second opening 8c is located on the bottom wall 81 and corresponds to the drain pump inspection port 11a in the front-back direction. This allows the drain pump plug to connect with the drain pump inspection port 11a without changing the conventional assembly position and maintenance path of the drain pump, ensuring that the original functions such as drainage, cleaning, and maintenance are not affected. This achieves reasonable avoidance and compatibility between the drying air duct and the drainage maintenance structure. The first opening 8b is located on the side wall 82, allowing the air outlet duct 6a and the air outlet cavity 8a to be laterally connected. This avoids the drain pump support structure from being too close to the second opening 8c, which could result in insufficient strength and affect the maintenance of the drain pump.

[0070] This layout makes full use of the limited space at the bottom of the housing 1, allowing the air outlet 8a, drainage pump installation, and maintenance passage to be arranged in an orderly manner within the same structure, further improving space utilization and structural compactness. It eliminates the need for additional transfer structures, simplifying the assembly process while enhancing the overall operational reliability and structural stability.

[0071] In some embodiments, combined with Figure 3 , Figure 6 and Figure 8 , Figure 8 This is a schematic diagram of the structure of the second fan 72 disclosed in the embodiment of this application. The fan assembly 7 includes a first fan 71 and a second fan 72. The first fan 71 is disposed in the air inlet duct 4a to drive the air outside the housing 1 into the air inlet duct 4a through the air inlet 12a. The second fan 72 is disposed in the air outlet duct 6a to drive the drying air in the outer cylinder 2 to be discharged through the air outlet duct 6a.

[0072] The first fan 71 is responsible for actively drawing in external air into the air inlet duct 4a and pushing it into the heating element 41 and the outer cylinder 2. The second fan 72 is responsible for drawing out the hot and humid drying air in the outer cylinder 2 and discharging it to the front. The two fans working together can increase the drying airflow and circulation speed, prevent airflow from stagnating or flowing back in the cylinder, and effectively improve drying efficiency and drying uniformity.

[0073] By employing separate and independently controlled inlet and outlet fans, the airflow of the drying system can be matched, avoiding problems such as uneven duct pressure, high air resistance, and high noise caused by a single fan relying solely on extraction or blowing. The two fans are respectively located on the inlet and outlet sides, and their respective speeds and operating times can be flexibly adjusted according to drying needs. This ensures that heated air can smoothly enter the drum while humid air is quickly discharged, improving the overall drying performance and operational stability of the machine.

[0074] In some embodiments, combined with Figure 3 and Figure 6 The first fan 71 includes an axial fan 711, the axis of rotation of which extends along the front-rear direction of the housing 1.

[0075] The air inlet duct 4a extends in the front-to-back direction, and the rotation axis of the axial fan 711 extends in the front-to-back direction of the housing 1. This saves space while giving full play to the structural advantages of the axial fan 711 and improving the air supply performance on the inlet side.

[0076] The axial fan 711 adopts an axial airflow structure, with the airflow direction consistent with the fan's rotation axis. It is adapted to the front and rear orientation of the air inlet 12a on the rear panel 12 and the air inlet duct 4a, which allows external air to enter the duct smoothly, reducing airflow turning and wind resistance, and ensuring smooth and stable air delivery.

[0077] While delivering the same airflow, the axial fan 711 is smaller and lighter than other types of fans, effectively reducing the space occupied in the air intake duct 4a, simplifying the duct structure design, improving the utilization rate of the internal space of the casing 1, and reducing the overall weight of the machine, thus reducing the load on the installation and support structures. The lightweight and compact structure of the axial fan 711 makes it more flexible to install in the limited space inside the washing machine, facilitating reasonable avoidance of the heating element 41, duct walls, and other structures, reducing assembly difficulty.

[0078] The axial fan 711 is suitable for high-flow, low-pressure air intake conditions, enabling a larger air intake volume under lower air pressure requirements. It quickly introduces and delivers external air into the heating element 41 and the outer cylinder 2, meeting the air intake volume requirements of the drying system. This design improves air intake efficiency and optimizes the structural layout, making the whole machine more compact, more reliable in operation, and easier to assemble while achieving efficient drying.

[0079] In some embodiments, combined with Figure 3 and Figure 8 The second fan 72 includes a centrifugal volute 721 and a centrifugal fan. The centrifugal volute 721 is located below the outer cylinder 2 and along the front-rear direction of the housing 1. The centrifugal volute 721 is situated between the outer cylinder 2 and the front plate 11. The centrifugal volute 721 includes an axial air inlet 721a and a radial air outlet 721b. The axial air inlet 721a communicates with the outlet of the air outlet duct 6a, and the radial air outlet 721b communicates with the air outlet hole 5a. The centrifugal fan is disposed inside the centrifugal volute 721, and the rotation axis of the centrifugal fan extends along the front-rear direction of the housing 1. Specifically, the radial air outlet 721b communicates with the air outlet cavity 8a through a first opening 8b.

[0080] The centrifugal volute 721 is arranged below the outer cylinder 2 and in the space between the outer cylinder 2 and the front plate 11. It can achieve a compact layout of the whole machine structure while making full use of the idle space at the bottom of the box 1, effectively saving installation space and improving the utilization rate of the internal space of the box 1.

[0081] The axial dimension of the centrifugal volute 721 is usually smaller than the radial dimension. The axis of the centrifugal volute 721 is arranged in the front-to-back direction and is adapted to the position of the air outlet duct 6a and the air outlet cavity 8a. Without increasing the width, thickness and height of the whole machine as much as possible, the drying air in the air outlet duct 6a is drawn into the air outlet cavity 8a of the drain pump bracket 8 located on the side of the outer cylinder 2 in the front-to-back direction of the box body 1, so as to achieve a combination of space utilization and functional realization.

[0082] The centrifugal fan itself features high air pressure and strong resistance, ensuring that the drying air absorbed by the outer cylinder 2 is stably extracted and smoothly discharged. This avoids problems such as poor ventilation and airflow backflow caused by high duct resistance, thus ensuring the continuity and efficiency of the drying cycle. At the same time, the centrifugal fan has high operational stability and low noise, maintaining stable operation even under high exhaust demand, reducing overall machine noise and improving the user experience of the garment processing device 100.

[0083] In some embodiments, combined with Figure 3 and Figure 5 The outer cylinder 2 is provided with a drying air inlet 2a and a drying air outlet 2b. The drying air inlet 2a is connected to the outlet of the air inlet duct 4a, and the drying air outlet 2b is connected to the inlet of the air outlet duct 6a. The drying air outlet 2b is located at the bottom of the housing 1 relative to the drying air inlet 2a, and the drying air outlet 2b and the drying air inlet 2a are arranged opposite each other along the radial direction of the outer cylinder 2.

[0084] After the drying air enters the outer cylinder 2 from one side inlet, it can pass through the inner cylinder 3 laterally and flow to the radially opposite outlet, fully penetrating the space inside the cylinder, avoiding problems such as local airflow short circuits and drying dead zones, and ensuring that both the inner cylinder 3 and the outer cylinder 2 can fully exchange heat with the high-temperature drying air.

[0085] Positioning the drying air outlet 2b near the bottom of the housing 1 allows the drying air to flow gradually from top to bottom throughout the entire cylinder cavity. This facilitates the removal of residual moisture that easily accumulates at the bottom of the inner cylinder 3 and outer cylinder 2, improving the self-drying effect of the cylinder and reducing problems such as odors and mold caused by moisture retention. Simultaneously, the radially opposite arrangement of the drying air inlet 2a and the drying air outlet 2b extends the effective residence time of the drying air within the cylinder, improving heat utilization and achieving better drying results with the same airflow and heating power.

[0086] This arrangement is fully adapted to the drum structure of the drum-type garment processing device 100. Without changing the overall structure of the outer drum 2 or taking up additional internal space, it optimizes the drying airflow path and improves the smoothness of airflow. This ensures stable entry and exit of drying air and improves the overall drying performance and operational reliability of the machine, achieving a dual optimization of structural layout and drying effect.

[0087] The drying air outlet 2b is located close to the opening of the outer cylinder 2 along the front-to-back direction of the housing 1. This further extends the flow path of the drying air in the front-to-back direction within the outer cylinder 2, improving the drying effect.

[0088] It should be noted that the outlet of the air inlet pipe 4 can extend between the outer cylinder 2 and the inner cylinder 3 through the drying air inlet 2a, or it can just connect with the drying air inlet 2a (i.e., it does not extend into the outer cylinder 2).

[0089] In some embodiments, combined with Figure 3 and Figure 5 The garment handling device 100 also includes an air outlet pipe 6, which has an air outlet duct 6a formed inside it. The air outlet pipe 6 is a flexible connecting pipe.

[0090] In this way, the flexible tube can be fully utilized to make flexible arrangement of exhaust paths in the limited and complex space inside the washing machine, effectively avoiding interference areas between rigid components such as the outer drum 2, drain pump, and cabinet 1, and improving the adaptability and space utilization of the air duct layout.

[0091] The flexible connecting pipe can freely adjust its direction and curvature according to the actual assembly environment, without having to strictly follow a fixed angle or straight line arrangement. It can make full use of the scattered and irregular idle space at the bottom and sides of the box 1, and avoid occupying additional effective space due to the fixed size and position of the rigid pipe. This makes the overall structure more compact and helps to reduce the overall size or optimize the internal space allocation.

[0092] Meanwhile, flexible connecting pipes have a higher fault tolerance rate and are easier to install during assembly. They can adapt to positional deviations between components and do not require a large assembly space for rigid pipe connections. This further saves installation space and simplifies assembly procedures. Under the premise of ensuring smooth airflow during drying, they achieve a dual improvement in space utilization and assembly convenience.

[0093] The flexible connecting pipe can be a pipe structure with a certain bending and deformation capability, such as a corrugated pipe, silicone pipe, rubber pipe, flexible plastic pipe or composite fiber flexible hose, and there is no limitation on it.

[0094] In some embodiments, combined with Figure 5 The garment handling device 100 also includes a switch valve 9, which is disposed inside the air outlet pipe 6 to open or close the air outlet pipe 6.

[0095] Thus, the switch valve 9 can controllably open or close the air outlet duct 6a according to the start and stop of the drying mode. In non-drying conditions, the air outlet duct can be reliably closed, which can effectively prevent water vapor, foam or washing water in the drum from flowing back into the air outlet duct during washing and dehydration, prevent the air outlet duct from accumulating dirt, odors and internal components from getting damp and damaged, and ensure the clean and stable operation of the whole machine.

[0096] In some embodiments, the garment handling apparatus 100 further includes a humidity sensor (not shown) disposed in the air outlet duct 6 and configured to detect the humidity of the drying air passing through the air outlet duct 6.

[0097] The humidity sensor can detect the humidity of the drying air flowing through the air outlet duct 6 in real time, providing feedback on the dryness level inside the outer drum 2. This provides a true and accurate basis for drying control, enabling automatic identification of the drying level. Together with the switching valve 9, heating element 41, and fan assembly 7, a closed-loop automatic control system can be formed. Drying is stopped promptly when the clothes or drum reach the preset dryness level, avoiding over-drying which could damage clothes and waste energy, and also preventing under-drying which could result in residual moisture, thus improving the accuracy and consistency of the drying effect.

[0098] The humidity sensor can be any device capable of detecting airflow humidity, such as a capacitive humidity sensor, a resistive humidity sensor, a thermistor humidity sensor, or an infrared humidity sensor; no specific limitation is made here.

[0099] Optionally, the humidity sensor is located between the switching valve 9 and the drying air outlet 2b, which is closer to the internal space of the outer cylinder 2, and the detected humidity is closer to the humidity inside the outer cylinder 2, thereby improving the drying effect and response speed.

[0100] Secondly, combining Figure 9 , Figure 9This is a flowchart of the automatic drying drum control method disclosed in the embodiments of this application. This application also discloses an automatic drying drum control method applied to the clothing handling device 100 in the first aspect described above. The clothing handling device 100 has an air inlet duct 4a, an air outlet duct 6a, a heating element 41, a fan assembly 7, a switching valve 9, and a humidity sensor. The heating element 41 is disposed in the air inlet duct 4a. The fan assembly 7 is connected to the air inlet duct 4a and / or the air outlet duct 6a. The humidity sensor is used to detect the humidity inside the outer drum 2. The switching valve 9 is disposed inside the air outlet duct 6a. The automatic drying drum control method includes: Select to enter automatic drum drying mode; Control valve 9, heating element 41 and fan assembly 7 to open; The humidity sensor detects whether the humidity inside the outer cylinder 2 has dropped to the preset humidity. If the humidity is less than or equal to the preset humidity, the control switch valve 9, heating element 41 and fan assembly 7 are closed; if the humidity is greater than the preset humidity, the drying cylinder operation continues.

[0101] By coordinating the control of the switching valve 9, heating element 41, fan assembly 7 and humidity sensor, the drying process can be fully automated without the need for manual start and stop by the user, thus improving the intelligence level and ease of use of the clothing processing device 100.

[0102] This method uses the real-time humidity of the drying air detected by the humidity sensor as the control basis. It can identify the drying status of the outer cylinder 2 and the inner cylinder 3. When the humidity drops to the preset humidity, the switch valve 9, the heating element 41 and the fan assembly 7 are automatically shut off. This can avoid residual moisture in the cylinder and odor caused by insufficient drying, and also prevent energy waste and component overheating caused by over-drying, thus achieving the optimal balance between drying effect and energy consumption control.

[0103] The control logic is simple and reliable. When used in the garment processing device 100 of the first aspect, it is highly compatible with the structural design of front air outlet, air duct integration, and dual fan drive. While realizing automatic drying of the drum and maintaining the dryness and hygiene of the whole machine, it does not increase the structural complexity and control cost, and further improves the user experience, operational stability and service life of the garment processing device 100.

[0104] The above embodiments are only used to illustrate the technical solutions of this application and do not constitute a limitation. The embodiments can be freely combined without conflict. Although each embodiment has been described in detail, those skilled in the art should understand that modifications can be made to the technical solutions or equivalent substitutions can be made to the technical features, and such modifications or substitutions should all be covered within the scope of the technical solutions of this application.
