Description

Technical Field

[0001] The present invention relates to a clothing processing device in a household appliance, specifically, to a clothing processing device having a hole-free drum and a drying function, and more particularly to a drum-type washer-dryer in which the drum is composed of a hole-free drum without dehydration holes, and more particularly to a door structure applied to the above-mentioned clothing processing device. Background Art

[0002] With the improvement of people's living standards, appliances such as washing and drying machines and clothes dryers with clothing drying functions have gradually entered the homes of the general public. However, existing washing and drying machines and clothes dryers generally have an air duct connected to the outer drum. The fan in the duct draws out the hot and humid air from the outer drum, thereby reducing the humidity inside the drum and drying the clothes.

[0003] Washing machines can generally be categorized as pulsator, agitator, and drum types. Generally speaking, washing machines remove stains from laundry using the action of water and detergent. Pulsator washing machines wash by rotating the pulsator in the center of the washing tub. Agitator washing machines wash by rotating the rotating blades in the center of the washing tub, utilizing the friction between the water flow and the laundry. Drum washing machines wash by tumbling the laundry in a rotating drum.

[0004] A drum-type washing machine generally has a housing with an outer tub for containing washing water installed inside, a drum for containing laundry provided inside the outer tub, and a motor and shaft for rotating the drum provided on the back of the outer tub.

[0005] Nowadays, a large amount of dirt is generally retained between the inner and outer drums of washing machines, whether they are pulsator type or drum type. In order to avoid contamination of the washing water, the applicant has previously proposed a hole-free drum washing machine that combines the inner and outer drums into one to overcome the problem of dirt retained between the inner and outer drums.

[0006] Therefore, how to apply the hole-free drum technology to a washer-dryer with drying function has become a research and development hotspot.

[0007] At the same time, since the holeless drum needs to have its mouth closed and needs to rotate during the drying process, how to improve the air intake rate and efficiency of the mouth of the rotatable holeless drum, especially the ventilation module installed at the mouth, has become a technical problem that needs to be solved urgently.

[0008] In view of this, the present invention is proposed. Summary of the Invention

[0009] The technical problem to be solved by the present invention is to overcome the shortcomings of the existing technology and provide a door structure to guide the airflow and improve the guiding effect of the door on the airflow; another purpose of the present invention is to provide a washer-dryer with a hole-free drum to achieve the purpose of ventilating the hole-free drum and the air duct and drying the clothes in the drum.

[0010] In order to solve the above technical problems, the basic concept of the technical solution adopted by the present invention is:

[0011] A door structure of a clothing processing device includes a door body, an air guide structure is provided on one side of the door body, the air guide structure includes an air inlet and an air outlet, an outlet air duct is provided at the air outlet of the air guide structure, and at least part of the outlet air duct is made of soft solid material.

[0012] Furthermore, the outlet air duct is cylindrical and communicates with the air outlet. One end of the outlet air duct is detachably mounted on the air outlet, and the other end extends horizontally toward a side away from the door body.

[0013] Furthermore, the end of the outlet air duct away from the door body is made of a soft solid material;

[0014] Preferably, the end of the outlet air duct away from the door body is made of a rubber material that can generate elastic deformation.

[0015] Furthermore, an inlet air duct is provided at the air inlet, and the inlet air duct is at least partially made of a soft solid material.

[0016] Furthermore, one end of the inlet air duct is detachably mounted on the air inlet, and the other end extends in a direction away from the air inlet. The end of the inlet air duct away from the air inlet is made of a soft solid material.

[0017] Furthermore, one end of the inlet air duct away from the air inlet at least partially extends out of the outer edge of the door, and the end portion thereof has the same curvature as the outer edge of the door.

[0018] Furthermore, the inlet air duct is tubular, and the end of the inlet air duct connected to the air inlet has the same shape as the air inlet. The opening at the end away from the air inlet gradually expands from the middle of the door body to the outer edge of the door body, and the side wall at the end extends horizontally outward.

[0019] Furthermore, a connection structure is provided at the portion where the inlet air duct and / or the outlet air duct is connected to the air guide structure.

[0020] Furthermore, an annular clip is provided around the outer wall of one end of the inlet air duct and / or outlet air duct connected to the air guide structure, and an annular clip corresponding to the annular clip is provided on the inner wall of the air guide structure, and the annular clip and the annular clip constitute a connecting structure.

[0021] The present invention provides a clothing processing device, which includes a shell and a drum, an air duct is arranged between the shell and the drum, and a door structure of the above-mentioned clothing processing device is installed at the clothing loading port of the shell, the inlet air duct on the door structure is connected to the air duct outlet end, and the outlet air duct faces the drum opening.

[0022] After adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art:

[0023] By arranging the above-mentioned air guide structure on the door body of the clothing processing device, the external air flow can be guided into the interior of the drum through the air guide structure. By arranging an outlet air duct at the air outlet of the air guide structure, the outlet air duct is directed toward the drum tube mouth, thereby reducing the air flow leakage between the air guide structure and the drum tube mouth. In particular, by arranging the outlet air duct to be at least partially made of soft solid material, the gap between the air outlet and the drum tube mouth can be further reduced, so that the outlet air duct can be closer to the drum tube mouth without affecting the rotation of the drum, which is a significant technical progress in improving the air flow.

[0024] At the same time, by setting an inlet air duct between the air inlet of the air guide structure and the air outlet end of the air duct, the inlet air duct is at least partially made of soft solid material, which can seal the air duct and the air guide structure when the door structure is closed, thereby allowing the airflow in the air duct to flow completely into the air guide structure.

[0025] Furthermore, both the inlet and outlet ducts are detachable from the air guide structure, making them easy to replace if their soft, solid materials become damaged. Furthermore, by providing these inlet and outlet ducts on the door, significant technological advancements have been achieved, including utilizing the door to guide airflow and improving the efficiency of air intake at the drum opening.

[0026] At the same time, the present invention has a simple structure, significant effects, and is suitable for popularization and use. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0037] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention but are not used to limit the scope of the present invention.

[0038] In the description of the present invention, it should be noted that the terms "upper", "lower", "inside", "outside", etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they cannot be understood as limiting the present invention.

[0039] In the description of the present invention, it should be noted that, unless otherwise specified or limited, the terms "mounted" and "connected" should be understood broadly. For example, they can refer to fixed, detachable, or integral connections; mechanical or electrical connections; and direct or indirect connections through an intermediary. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0040] like Figures 1 to 6 As shown, an embodiment of the present invention introduces a clothing processing device, which includes a drum 2 for independently holding washing water when washing clothes, thereby avoiding the problem of cross-flow of washing water inside and outside the drum 2 during the washing process of the washing machine, causing the washing water to be contaminated by dirt and bacteria accumulated outside the drum; a drying system for drying the load in the drum 2 to obtain dry clothes, etc., thereby achieving the effect of improving the quality of life of users.

[0041] In an embodiment of the present invention, the drying system includes an air duct 5 which is connected to the drum 2 at both ends to form a circulating air path; a fan 4 is installed in the air duct 5, so that a circulating airflow flowing in a single direction is formed in the circulating air path formed by the drum 2 and the air duct 5; a dehumidification device 20 is also installed in the air duct 5 to dehumidify the circulating air flow flowing through it, so as to achieve the effect of reducing the humidity of the air flow in the circulating air path and drying the load in the drum 2; at the same time, in an embodiment of the present invention, in order to increase the drying rate of the load in the drum 2 and accelerate the vaporization of water adsorbed in the load, a heating device 3 can be set in the air duct 5 to heat the circulating air flow flowing through it, thereby achieving the effect of increasing the temperature in the drum 2, heating the load in the drum 2 and accelerating the drying rate.

[0042] In an embodiment of the present invention, when the clothes processing device executes a drying program, the drying system is controlled to start, and the fan 4 is used to form a circulating airflow in the circulating air path formed by the air duct 5 and the drum 2. The circulating airflow fully contacts the load in the drum 2 when flowing through the drum 2, and after carrying the moisture in the load, it becomes moist and hot drying air, flows out of the drum 2 and flows into the air duct 5. After the moist and hot drying air flows into the air duct 5, it contacts the dehumidification device 20 in the air duct 5, so that the moist and hot drying airflow is converted into a dry drying airflow and then flows back into the drum 2, and the circulation continues in this way. Preferably, in order to increase the drying rate, a heating device 3 can be added to the air duct 5, so that the dry drying airflow after being dehumidified by the dehumidification device 20 contacts the heating device 3, is heated, and forms a high-temperature dry drying airflow before it flows back into the air duct 5.

[0043] In an embodiment of the present invention, the drying system can be any existing device capable of dehumidifying and drying clothing, such as a heat pump system. The heat pump system comprises a compressor, an evaporator, a throttling device, and a condenser connected end-to-end to form a circulation flow path for circulating a cooling medium. A condenser and an evaporator are installed in the air duct 5 of the clothing processing device, arranged in sequence along the flow direction of the circulating airflow, so that the airflow flowing out of the drum 2 first undergoes heat exchange with the evaporator to condense and separate the water vapor contained therein, then undergoes heat exchange with the condenser to heat it and form a high-temperature dry airflow. Finally, the high-temperature dry airflow is returned to the drum 2 to reduce the humidity and increase the temperature in the drum 2, thereby achieving the effect of drying the load in the drum 2. Thus, the evaporator of the heat pump system constitutes the dehumidification device 20, and the condenser constitutes the heating device 3, thereby achieving the effect of drying the load in the drum 2.

[0044] In the embodiment of the present invention, in order to ensure that the drum 2 is rotatably installed in the housing 18 of the laundry processing device and is connected to the air duct 5 fixed in the housing 18, the following settings are performed:

[0045] like Figure 1 As shown, in one embodiment of the present invention, a laundry processing device includes a housing 18, within which is housed an outer drum 1. The outer drum 1 is connected to the washing machine housing 18 at the top and bottom via shock-absorbing suspension springs and shock-absorbing support rods, respectively, to ensure that the outer drum 1 is vibratingly mounted within the washing machine housing 18. A coaxially mounted drum 2 is housed within the outer drum 1. The outer drum 1 and the drum 2 are formed, respectively, by cylindrical sidewalls of the outer drum 1 and the drum 2. Opposite openings are provided on corresponding ends of the outer drum 1 and the drum 2 on the same side, forming a drum opening 201 and an outer drum opening 101, respectively. The corresponding ends on the other sides are sealed, forming a drum bottom 202 and an outer drum bottom 102, respectively. Furthermore, an outwardly openable door 7 is mounted at the front end of the washing machine housing 18, which can be opened or closed to open or close the outer drum opening 101. An outwardly openable drum door 10 is mounted on the drum 2, which can be opened or closed to open or close the drum opening 201. Thus, the effect of installing a drum 2 within the outer drum 1, which can rotate relative to the outer drum 1 and forms a closed water container during washing, is achieved. The air duct 5 is connected to the outer drum 1 at both ends, and a ventilation hole is provided on the drum 2, which communicates with the outer drum 1. The ventilation module 8 is installed at the ventilation hole to achieve the purpose of forming a circulating air path through the air duct 5 through the outer drum 1 and the rotating drum 2, thereby drying the load in the drum 2.

[0046] In an embodiment of the present invention, the center of the drum bottom 202 is coaxially arranged with the motor shaft of the washing machine drive motor to drive the drum 2 to rotate. The drum 2 and the drive motor are both fixedly mounted on the outer drum 1. Preferably, the drum bottom 202 and the drive motor are respectively arranged on either side of the outer drum bottom 102. The drive motor is fixedly connected to the outer drum 1. The motor shaft of the drive motor passes through the outer drum bottom 102 via a bearing and is coaxially fixedly connected to the drum bottom 202. The motor shaft of the drive motor can rotate relative to the outer drum 1, thereby achieving the purpose of installing the drum 2 and the drive motor on the outer drum 1 and allowing the drum 2 to rotate independently under the action of the drive motor to wash the clothes inside. Preferably, the motor shaft of the drive motor directly constitutes the axis of the drum 2, and the axis of the drum 2 is coaxially fixedly connected to the drum bottom 202 of the drum 2.

[0047] Preferably, in this embodiment of the present invention, an air guide structure 9 is provided on one side of the door body 7 to guide the airflow in the air duct 5 into the drum 2 to dry the load in the drum 2. The air guide structure 9 includes an air inlet 12 and an air outlet 13. The air inlet 12 is connected to the air outlet end of the air duct 5, and the air outlet 13 is opened toward the drum opening 201. In order not to affect the normal rotation of the drum 2, a gap is left between the air outlet 13 and the drum opening 201.

[0048] Preferably, an outlet duct 15 is provided at the air outlet 13 of the air guide structure 9, and at least a portion of the outlet duct 15 is made of a soft solid material (e.g., rubber). By providing the outlet duct 15 at the air outlet 13 of the air guide structure 9, the outlet duct 15 faces the drum opening 201, thereby reducing the gap between the air outlet 13 and the drum opening 201. By making at least a portion of the outlet duct 15 of a soft solid material, the outlet duct 15 can further reduce the gap between the air outlet 13 and the drum opening 201 without affecting the normal rotation of the drum 2, thereby minimizing airflow leakage and improving the effectiveness of the airflow.

[0049] Example 1

[0050] like Figures 1 to 3 and Figure 5 As shown, this embodiment introduces a door structure of a clothing processing device, which includes a door body 7, an air guide structure 9 is provided on one side of the door body 7, and the air guide structure 9 includes an air inlet 12 and an air outlet 13. An outlet air duct 15 is provided at the air outlet 13 of the air guide structure 9, and at least a part of the outlet air duct 15 is made of soft solid material (such as rubber).

[0051] In this embodiment, the outlet air duct 15 is cylindrical and communicates with the air outlet 13. One end of the outlet air duct 15 is detachably connected to the air outlet 13, and the other end extends horizontally toward the side away from the door body 7. The end of the outlet air duct 15 away from the door body 7 is made of a self-deformable rubber material.

[0052] Preferably, in this embodiment, the air guide structure 9 is an air duct. The air duct is a hollow channel structure, one end of which is flush with the outer edge of the door body 7 and is open, forming an air inlet 12. The other end is located in the middle of the door body 7 and is closed. The closed end 702 is opened toward one side of the door body 7, forming an air outlet 13. The air duct is flat as a whole, and the closed end 702 of the air duct is a circular arc surface that narrows from the open end to the closed end 702. The air duct is provided with a deflector arranged along the direction of air flow. The deflector is integrally formed with the air duct and is evenly arranged within the air duct to enhance the airflow guidance performance of the air duct. By providing this air duct, the airflow from the outlet end of the air duct 5 can be guided, preventing the airflow from leaking through the gaps in the door structure during the process of flowing through the door structure, thereby enhancing the airflow guidance effect of the door structure.

[0053] In this embodiment, the door body 7 is a vertically arranged plate structure. A horizontally outwardly protruding portion 701 is provided on a vertical side surface of the door body 7 where the air guide is provided. The protruding portion 701 is recessed from the outer edge of the door body 7 toward the center of the door body 7 to form the air guide. Thus, the protruding portion 701 on the door body 7 utilizes its internal hollow space and / or enclosed space to form the air guide, thereby achieving the technical effect of guiding airflow. This arrangement simplifies the installation process of the air guide. Furthermore, in this embodiment, the protruding portion 701 can be integrally formed with the door body 7, or it can be formed from another independent component that can be detachably mounted on the door body 7.

[0054] Preferably, in this embodiment, the air guide duct is a hollow structure, one end of which is flush with the outer edge of the door body 7 and is open, and the opening constitutes the air inlet 12, and the other end is in the middle of the door body 7 and is closed, and an opening concentric with the door body 7 is provided on the side of the closed end 702 away from the door body 7, and the opening constitutes the air outlet 13.

[0055] Preferably, in this embodiment, a connection structure is provided at the portion where the outlet air duct 15 is connected to the air guide duct.

[0056] In this embodiment, an annular locking protrusion 1701 is provided around the outer wall of the outlet air duct 15 at one end connected to the air guide duct, and an annular locking groove 1702 corresponding to the annular locking protrusion 1701 is provided on the inner wall of the air guide duct. The annular locking protrusion 1701 and the annular locking groove 1702 constitute a connecting structure.

[0057] Preferably, in this embodiment, the end of the outlet air duct 15 away from the door body 7 is made of a deformable material such as rubber.

[0058] Example 2

[0059] like Figures 1 to 4As shown, this embodiment introduces a door structure of a clothing processing device, which includes a door body 7, an air guide structure 9 is provided on one side of the door body 7, and the air guide structure 9 includes an air inlet 12 and an air outlet 13. An inlet air duct 6 is provided at the air inlet 12 of the air guide structure 9, and the inlet air duct 6 is at least partially made of soft solid material (such as rubber).

[0060] In this embodiment, the air guide structure 9 is an air duct. The door body 7 is a vertically arranged plate structure. A horizontally outwardly projecting protrusion 701 is provided on a vertical side surface of the door body 7 where the air duct is located. The protrusion 701 is recessed from the outer edge of the door body 7 toward the center of the door body 7 to form the air duct. Thus, the protrusion 701 on the door body 7 utilizes its internal hollow space and / or enclosed space to form the air duct, thereby achieving the technical effect of guiding airflow.

[0061] Preferably, in this embodiment, one end of the inlet duct 6 is detachably connected to the air inlet 12, and the other end extends away from the air inlet 12. The end of the inlet duct 6 away from the air inlet 12 is made of a deformable rubber material. In this embodiment, the end of the inlet duct 6 away from the air inlet 12 is made of a deformable rubber or other material.

[0062] Preferably, in this embodiment, one end of the inlet duct 6 away from the air inlet 12 at least partially extends out of the outer edge of the door body 7 , and the end of the inlet duct 6 away from the air inlet 12 has the same curvature as the outer edge of the door body 7 .

[0063] Preferably, in this embodiment, the inlet air duct 6 is tubular, and the end of the inlet air duct 6 connected to the air inlet 12 has the same shape as the air inlet 12, and the opening at the end away from the air inlet 12 gradually expands from the middle of the door body 7 to the outer edge of the door body 7, and the side wall at the end extends horizontally outward.

[0064] Preferably, in this embodiment, a connection structure is provided at the portion where the inlet duct 6 connects to the air guide duct. In this embodiment, an annular latching protrusion 1701 is provided around the inlet duct 6 on the outer wall at one end where the inlet duct 6 connects to the air guide duct, and an annular latching groove 1702 corresponding to the annular latching protrusion 1701 is provided on the inner wall of the air guide duct. The annular latching protrusion 1701 and the annular latching groove 1702 constitute the connection structure.

[0065] Example 3

[0066] like Figure 6 As shown, this embodiment introduces a ventilation module 8, including a shell 801, which forms a hollow channel. Retaining ribs 803 are arranged at both ends of the channel. The retaining ribs 803 separate the two ends of the channel into multiple hollow holes 802, and each hollow hole 802 connects the inside and outside of the channel.

[0067] Through the above-mentioned arrangement, the two sides of the ventilation module 8 can be connected through the hollow holes 802 of the connecting channels at both ends, so that the airflow on both sides of the ventilation module 8 can flow through the channels and achieve the purpose of free exchange and flow of gas on both sides under the action of pressure difference; at the same time, by arranging a plurality of hollow holes 802 arranged at intervals at the end of the ventilation module 8, the airflow flowing through can be evenly distributed under the action of the hollow holes 802, thereby improving the uniformity of the airflow flowing into the drum 2.

[0068] In this embodiment, the hollow holes 802 at both ends of the passage of the ventilation module 8 can be arranged in a staggered manner so that the airflow does not pass directly through, but rather uses the return channel to pass through. This ensures that water trapped in the airflow is trapped by the return channel, effectively preventing the water from flowing out of the ventilation module 8. Of course, in this embodiment, the hollow holes 802 at both ends of the ventilation module 8 can also be arranged in any other manner, while still achieving the above-mentioned inventive objectives.

[0069] Preferably, in this embodiment, the projections of the hollow holes 802 at both ends of the channel along the channel axis in the same vertical section are at least partially staggered, so that the channel of the breathable module 8 and the hollow holes 802 at both ends together form a folded gas flow channel, which can effectively intercept water trapped in the air flow and prevent water from flowing out of the breathable module 8.

[0070] The channel cross-section of the ventilation module 8 can be any shape, such as: circular, polygonal, elliptical, etc.; preferably, in this embodiment, in order to adapt to the shape of the drum 2, improve ventilation efficiency, and improve airflow uniformity, the ventilation module 8 can be set to a disc shape, and the cross-section of the ventilation channel is set to be circular.

[0071] In this embodiment, the two ends of the circular channel are the first end 81 and the second end 82 respectively. The first end 81 and the second end 82 are respectively provided with a retaining rib 803. The retaining rib 803 is used to separate the first end 81 and the second end 82 into a plurality of hollow holes 802, so as to achieve the effect that the two ends of the channel can exchange airflow with the outside through the arranged hollow holes 802.

[0072] In this embodiment, the channel is a tapered channel with a gradually narrowing radial dimension from first end 81 to second end 82. The tapered sidewalls of the channel guide water flowing into the channel back toward first end 81, thereby effectively preventing trapped water from accumulating within the channel. In this embodiment, to achieve the desired effect of trapped water flowing back toward first end 81 and then into the washing machine drum, the channel is mounted on drum 2 with first end 81 facing the interior of the washing machine drum and second end 82 facing the exterior of the washing machine drum. This prevents water from escaping through the air vents.

[0073] In this embodiment, a plurality of hollow holes 802 are arranged at intervals on the inner peripheral wall of the first end 81 of the channel, so that the lowest point of the first end 81 of the channel is the hollow hole 802. This ensures that when the water trapped in the channel flows back along the tapered side wall to the first end 81, it can flow back to the drum 2 through the lowest hollow hole 802, further preventing the occurrence of water accumulation in the channel.

[0074] Preferably, in this embodiment, the ventilation module 8 can be provided integrally with the drum 2 or separately;

[0075] Preferably, in this embodiment, the outer periphery where the second end 82 of the channel of the ventilation module 8 is connected to the channel side wall is set as a circle of arc chamfered surface, so as to utilize the arc chamfered surface to prevent problems such as clamping and scratching of clothes.

A ring-shaped window gasket 11 is connected between the outer drum opening 101 and the outer periphery of the clothing loading port of the housing 18. An air duct extends from the door body 7 into the space enclosed by the ring-shaped window gasket 11. The ring-shaped window gasket 11 is provided with a joint 19 that is opened opposite to the air inlet 12 of the air duct. The joint 19 is connected to the air outlet end of the air duct 5 of the clothing processing device, so that the airflow out of the air duct 5 can be guided into the space enclosed by the ring-shaped window gasket 11 through the joint 19. The air outlet 13 of the air duct is opened toward the drum opening 201, so that the airflow flowing into the air duct from the air duct 5 is guided by the air duct and flows into the interior of the drum 2. Preferably, in this embodiment, the joint 19 is provided above the ring-shaped window gasket 11 and extends along the radial direction of the door body 7.

[0078] Preferably, in this embodiment, an inlet duct 6 is provided at the air inlet 12 of the air guide duct, one end of the inlet duct 6 is detachably connected to the air inlet 12, and the other end extends in a direction away from the air inlet 12. The end of the inlet duct 6 away from the air inlet 12 is made of a deformable material such as rubber.

[0079] Preferably, in this embodiment, a connection structure is provided at the portion where the inlet duct 6 connects to the air guide duct. In this embodiment, an annular latching protrusion 1701 is provided around the inlet duct 6 on the outer wall at one end where the inlet duct 6 connects to the air guide duct, and an annular latching groove 1702 corresponding to the annular latching protrusion 1701 is provided on the inner wall of the air guide duct. The annular latching protrusion 1701 and the annular latching groove 1702 constitute the connection structure.

[0080] Preferably, in this embodiment, the end of the inlet duct 6 away from the air inlet 12 at least partially extends out of the outer edge of the door body 7, and the end of the inlet duct 6 away from the air inlet 12 has the same curvature as the outer edge of the door body 7. When the door body 7 is closed, the air inlet end of the inlet duct 6 is aligned with and squeezed with the joint 19, so that the air flow from the air outlet end of the air duct 5 can flow completely into the air guide duct without leakage between the air duct 5 and the air guide duct. The inlet duct 6 is tubular, and the end of the inlet duct 6 connected to the air inlet 12 has the same shape as the air inlet 12. The opening at the end away from the air inlet 12 gradually expands from the middle of the door body 7 to the outer edge of the door body 7, so that the air inlet end of the inlet duct 6 is larger than the joint 19. The side wall at the end extends horizontally outward, so that the inlet duct 6 and the joint 19 on the air duct 5 fit more closely. When the door body 7 is closed, the air inlet end of the inlet duct 6 covers the joint 19, which can effectively improve the air flow transmission efficiency.

[0081] Preferably, in this embodiment, at least one ventilation module 8 is provided on the drum 2 to facilitate air exchange between the inside and outside of the drum 2, thereby achieving ventilation between the drum 2 and the external air duct 5. Furthermore, by providing an air duct on the door 7 of the clothing processing device, with the air duct on the door structure facing the drum opening 201, external airflow is directed into the drum 2 through the air duct, thereby significantly improving air flow during the drying process of the clothing processing device.

[0082] In this embodiment, a ventilation module 8 protruding toward the door body 7 is provided at the center of the drum door 10. A gap is maintained between the ventilation module 8 and the air duct to ensure that there is a safe distance between the ventilation module 8 and the air duct during the operation of the drum 2, so as to effectively prevent the two from colliding with each other and other problems.

[0083] Preferably, in this embodiment, an outlet duct 15 is provided at the air outlet 13 of the air guide duct. The outlet duct 15 is cylindrical and communicates with the air outlet 13. One end of the outlet duct 15 is detachably mounted on the air outlet 13, and the other end extends horizontally toward a side away from the door body 7. The end of the outlet duct 15 away from the door body 7 is made of a deformable material such as rubber.

[0084] By arranging an outlet air duct 15 between the air outlet 13 and the ventilation module 8, the outlet air duct 15 faces the ventilation module 8, and the gap between the air outlet 13 and the ventilation module 8 is reduced, thereby reducing the air flow leakage between the air guide duct and the ventilation module 8. At the same time, by making the outlet air duct 15 close to the ventilation module 8 at one end using deformable rubber or other materials, the outlet air duct 15 can be closer to the ventilation module 8. During the rotation of the drum 2, even if the outlet air duct 15 comes into contact with the ventilation module 8, no violent collision will occur, thereby not only ensuring safety, but also reducing the leakage of air flow between the outlet air duct 15 and the ventilation module 8, thereby improving the effect of the air flow.

[0085] Preferably, in this embodiment, the portion of the outlet duct 15 connected to the air guide duct is provided with a connecting structure. An annular retaining protrusion 1701 is provided around the outer wall of the end of the outlet duct 15 connected to the air guide duct, and an annular retaining groove 1702 corresponding to the annular retaining protrusion 1701 is provided on the inner wall of the air guide duct. The annular retaining protrusion 1701 and the annular retaining groove 1702 form a connecting structure. Thus, the outlet duct 15 is movably mounted on the air guide duct. Even if the ventilation module 8 comes into contact with the outlet duct 15 during the rotation of the drum 2, the outlet duct 15 will cushion the impact force through its rubber portion and / or rotate a certain number of times with the ventilation module 8, thereby dissipating the collision force without causing any danger.

[0086] In this embodiment, the inlet air duct 6 and the outlet air duct 15 are both detachable independent parts. When the inlet air duct 6 or the outlet air duct 15 is damaged, affecting its use effect, it can be replaced separately, which is convenient to use and low cost.

Although the present invention has been disclosed as above in terms of a preferred embodiment, it is not intended to limit the present invention. Any technician familiar with this patent can make slight changes or modifications to equivalent embodiments using the above-mentioned technical contents without departing from the scope of the technical solution of the present invention. However, any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the solution of the present invention.
