Description

Technical Field

[0001] This invention relates to a clothing handling device for household appliances, specifically to a clothing handling device with a non-perforated drum and a drying function, particularly to a drum-type washer-dryer with a drum consisting of a non-perforated drum without dehydration holes, and especially to a door structure applied to the above-mentioned clothing handling device. Background Technology

[0002] As people's living standards improve, washer-dryer combos and dryers with clothes drying functions are gradually entering people's homes. However, existing washer-dryer combos and dryers generally connect an air duct to the outer drum and install a fan in the air duct to extract the hot and humid air from the outer drum, thereby reducing the humidity inside the drum and drying the clothes.

[0003] Washing machines can be broadly categorized into top-loading, agitator, and front-loading types. Generally, washing machines remove dirt from clothes through the action of water and detergent.

[0004] Top-loading washing machines wash clothes by rotating a pulsator in the center of the tub. Agitator washing machines wash clothes by rotating agitator vanes in the center of the tub, utilizing the friction between the water and the clothes. Front-loading washing machines wash clothes by tumbling them with a rotating drum.

[0005] A drum washing machine typically has a shell, an outer drum for holding washing water installed inside, a drum for holding laundry inside the outer drum, and a motor and shaft for rotating the drum on the back of the outer drum.

[0006] Currently, whether it is a top-loading or front-loading washing machine, a large amount of dirt generally remains between the inner and outer drums. In order to avoid contaminating the washing water, the applicant previously proposed a holeless front-loading washing machine that combines the inner and outer drums into one, in order to overcome the problem of dirt remaining between the inner and outer drums.

[0007] Therefore, how to apply the non-porous drum technology to washer-dryer combos with drying functions has become a research hotspot.

[0008] Meanwhile, since the non-perforated drum needs to have its opening sealed and it needs to rotate during the drying process, how to improve the air intake rate and efficiency at the opening of the rotatable non-perforated drum, especially the air venting module at the opening, has become an urgent technical problem to be solved.

[0009] In view of this, the present invention is proposed. Summary of the Invention

[0010] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a door structure to guide airflow and improve the guiding effect of the door on airflow; another objective of the present invention is to provide a washer-dryer with a non-perforated drum to achieve the purpose of exchanging air between the non-perforated drum and the air duct and drying the clothes inside the drum.

[0011] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by the present invention is as follows:

[0012] A door structure for a garment handling device includes a door body with an air guide duct. The air guide duct is a hollow channel structure, with one end flush with the outer edge of the door body and open to form an air inlet, and the other end in the middle of the door body and closed. An opening is provided on one side of the closed end facing the door body, forming an air outlet.

[0013] Furthermore, the air duct is generally flat, the closed end of the air duct is an arc surface coaxial with the door body, and the air outlet of the air duct is concentric with the door body.

[0014] Furthermore, the cross-sectional width of the air guide duct gradually narrows from the outer edge of the door body towards the middle of the door body.

[0015] Furthermore, the air duct is provided with a support plate arranged along the airflow direction.

[0016] Furthermore, the door body is a vertically arranged plate structure, and a horizontally outward protrusion is provided on the vertical side of the door body where the air guide duct is located.

[0017] Furthermore, the hollow space inside the protrusion forms an air duct.

[0018] Furthermore, the air duct is set up separately and installed on the protruding part of the door.

[0019] Furthermore, the protruding part is a rib extending along the "U" shape. The structure enclosed by the "U" shaped rib has an open top and a closed bottom. A separately set air guide is installed inside the "U" shaped rib.

[0020] The present invention provides a clothing handling device, which includes a drum installed inside the outer casing and forming a sealed water container when the washing machine is in the washing state; a door structure of the above-mentioned clothing handling device is installed at the clothing loading port of the outer casing, and the air outlet of the air guide duct on the door structure faces the drum opening.

[0021] Furthermore, when the clothing loading port of the closed outer shell of the door structure is in place, the air inlet of the air guide duct corresponds to the air outlet of the ventilation duct.

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

[0023] By installing the aforementioned air guide ducts on the door of the garment processing device, external airflow is guided into the drum, preventing airflow leakage from gaps in the device structure and improving the airflow effect. This results in a significant improvement in gas flow during the drying process. Furthermore, by aligning the air guide ducts on the door towards the drum opening, external airflow is guided into the drum, further enhancing gas flow during the drying process. This also represents a significant technological advancement in utilizing the door to guide airflow and improve the efficiency of air intake at the drum opening.

[0024] At the same time, the present invention has a simple structure, significant effects, and is suitable for widespread use.

[0025] The specific embodiments of the present invention will now be described in further detail with reference to the accompanying drawings. Attached Figure Description

[0034] To make the objectives, 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 with reference to the accompanying drawings. The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0035] In the description of this invention, it should be noted that the terms "upper", "lower", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0036] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0037] like Figures 1 to 5 As shown in the figure, an embodiment of the present invention introduces a clothing processing device, which includes a drum 2, which independently holds the washing water when washing clothes, avoiding the problem of washing water flowing cross-flowing 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; and a drying system, which is used to dry the load in the drum 2 to obtain dry clothes, etc., thereby improving the user's quality of life.

[0038] In this embodiment of the invention, the drying system includes an air duct 5 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 one 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 airflow, so as to reduce the humidity of the airflow in the circulating air path and dry the load in the drum 2; at the same time, in order to improve 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 airflow, thereby increasing the temperature in the drum 2 and heating the load in the drum 2 to accelerate the drying rate.

[0039] In this embodiment of the invention, when the clothing processing device executes the drying program, the drying system is started. The fan 4 causes a circulating airflow to form in the circulating air path formed by the air duct 5 and the drum 2. As the circulating airflow flows through the drum 2, it fully contacts the load in the drum 2, carrying away moisture from the load and becoming hot, humid drying air. This airflow then flows out of the drum 2 and into the air duct 5. After flowing into the air duct 5, the hot, humid drying air comes into contact with the dehumidification device 20 in the air duct 5, causing the hot, humid drying airflow to become dry drying airflow before flowing back into the drum 2. This cycle repeats continuously. Preferably, to improve the drying rate, a heating device 3 can be installed in the air duct 5, so that the dry drying airflow, after being dehumidified by the dehumidification device 20, comes into contact with the heating device 3, heating it to form a high-temperature dry drying airflow before flowing back into the air duct 5.

[0040] In this embodiment of the invention, the drying system can be any existing device capable of dehumidifying and drying clothes, such as a heat pump system. The heat pump system consists of a compressor, evaporator, throttling device, and condenser connected sequentially to form a circulating flow channel for the cooling medium. A condenser and evaporator are installed sequentially along the direction of the circulating airflow in the air duct 5 of the clothes handling device. This allows the airflow from the drum 2 to first exchange heat with the evaporator, condensing and separating the water vapor it contains, then exchange heat with the condenser to heat it and form a high-temperature dry airflow. Finally, the high-temperature dry airflow flows back into the drum 2, thereby reducing the humidity and increasing the temperature in the drum 2, thus achieving the effect of drying the load in the drum 2. Therefore, the evaporator of the heat pump system is configured as a dehumidifying device 20, and the condenser as a heating device 3, to achieve the effect of drying the load in the drum 2.

[0041] In this embodiment of the invention, in order to ensure that the roller 2 is rotatable around its axis and connected to the air duct 5 installed in the outer casing 18 of the garment processing device and fixed in the outer casing 18, the following settings are made:

[0042] like Figure 1As shown, in this embodiment of the invention, the clothing handling device includes a housing 18, inside which is an outer drum 1. The outer drum 1 is connected to the washing machine housing 18 via shock-absorbing springs and shock-absorbing support rods at its top and bottom, respectively, so as to achieve the purpose of the outer drum 1 being vibratingly installed inside the washing machine housing 18. A coaxially arranged drum 2 is fitted inside the outer drum 1. The outer drum 1 and the drum 2 are respectively composed of a cylindrical outer drum 1 side wall and a drum 2 side wall. Corresponding ends on the same side of the outer drum 1 and the drum 2 are provided with openings to form a drum opening 201 and an outer drum opening 101, respectively. Corresponding ends on the other side are sealed to form a drum bottom 202 and an outer drum bottom 102, respectively. At the same time, an outwardly opening door 7 is installed at the front end of the washing machine housing 18, so as to close or open the outer drum opening 101 by opening and closing the door 7; and an outwardly opening drum door 10 is installed on the drum 2, so as to close or open the drum opening 201 by opening and closing the drum door 10. Thus, the effect of installing a drum 2, which can rotate relative to the axis and forms a closed water container during washing, is achieved in the outer drum 1. The two ends of the air duct 5 are connected to the outer drum 1 respectively, and the drum 2 is provided with a vent hole that communicates with the outer drum 1. A vent module 8 is installed at the vent hole to achieve the purpose of forming a circulating air path between the air duct 5 and the rotating drum 2 through the outer drum 1, and drying the load in the drum 2.

[0043] In this embodiment of the 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. Both the drum 2 and the drive motor are fixedly mounted on the outer drum 1. Preferably, the drum bottom 202 and the drive motor are respectively arranged on both sides 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, so as to achieve the purpose of mounting 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 shaft of the drum 2, and the shaft of the drum 2 is coaxially fixedly connected to the drum bottom 202 of the drum 2.

[0044] Example 1

[0045] like Figures 1 to 4 As shown in the figure, this embodiment introduces a door structure of a clothing handling device, which includes a door body 7. An air guide duct 9 is bolted to one side of the door body 7. The air guide duct 9 is a hollow channel structure. One end of the air guide duct is flush with the outer edge of the door body 7 and is open, forming an air inlet 12. The other end is in the middle of the door body 7 and is closed. The closed end 702 is provided with an opening concentric with the door body 7 on one side facing the door body 7, forming an air outlet 13.

[0046] The air guide duct 9 is separately provided and is generally flat. The closed end 702 of the air guide duct 9 is an arc surface 703 that narrows from the open end to the closed end 702. The side wall of the air guide duct 9 near the door body 7 is formed by an inclined surface that gradually slopes from the outer edge of the door body 7 towards the middle of the door body 7 towards the open end. A support plate 14 is provided inside the air guide duct 9 along the airflow direction. The support plate 14 is integrally formed with the air guide duct 9 and is evenly distributed inside the air guide duct 9 to enhance the airflow guiding performance of the air guide duct 9. By setting up this air guide duct 9, the airflow from the air outlet of the air duct 5 can be guided, preventing the airflow from leaking into the gaps in the door structure during the flow of air through the door structure, and enhancing the door structure's airflow guiding effect.

[0047] The door body 7 is a vertically arranged plate structure. On one vertical side of the door body 7 where the air duct 9 is installed, there is a horizontally outwardly protruding portion 701. The protruding portion 701 is a U-shaped rib 16 extending along a "U" shape. The U-shaped rib 16 forms a structure with an open upper end and a closed lower end, and its shape is adapted to the air duct 9 for installation. The air duct 9 is fixedly installed in the protruding portion 701 of the door body 7 by bolts and fits snugly against the door body 7. By setting this "U"-shaped rib 16, an installation groove is provided for the air duct 9 to support it. During installation, the outer wall of the air duct 9 is completely fitted into the installation groove, positioning the air duct 9 and simplifying the installation process.

[0048] Preferably, in this embodiment, the air outlet 13 protrudes horizontally outward. By setting the air outlet 13 of the air guide duct 9 to protrude outward, the airflow exiting the air guide duct 9 is guided.

[0049] Preferably, in this embodiment, the air duct 9 can be made of a material such as glass that cannot be deformed, or it can be made of a material such as rubber that can be deformed.

[0050] Preferably, in this embodiment, the sidewall of the air guide duct 9 has a uniform thickness.

[0051] like Figure 1As shown, in this embodiment, the outer casing 18 is provided with an outer cylinder 1, and the roller 2 is coaxially fitted inside the outer cylinder 1. An annular window pad 11 is connected between the outer cylinder opening 101 and the outer periphery of the clothing loading port of the outer casing 18. The air guide duct 9 extends from the door body 7 into the space enclosed by the annular window pad 11. The annular window pad 11 is provided with a connector 19 that is opened opposite to the air inlet 12 of the air guide duct 9. The connector 19 is connected to the air outlet of the air duct 5 of the clothing handling device, so that the airflow from the air duct 5 can be guided into the space enclosed by the annular window pad 11 through the connector 19. The air outlet 13 of the air guide duct 9 is opened towards the roller opening 201, so as to achieve the effect of guiding the airflow from the air duct 5 into the air guide duct 9 into the interior of the roller 2. Preferably, in this embodiment, the connector 19 is located above the annular window pad 11 and extends radially along the door body 7.

[0052] Preferably, in this embodiment, when the door 7 is closed, the air inlet 12 of the air guide duct 9 is aligned with and squeezed against the outlet of the connector 19. This ensures that the airflow from the outlet of the air duct 5 into the air guide duct 9 is completely contained and there is no leakage between the air duct 5 and the air guide duct 9.

[0053] Preferably, in this embodiment, the top of the air inlet 12 of the air guide duct 9 is larger than the opening of the connector 19. When the door 7 is closed, the top of the air inlet 12 of the air guide duct 9 covers the opening of the connector 19, which can effectively improve the airflow transmission efficiency.

[0054] Example 2

[0055] like Figure 5 As shown in the figure, this embodiment introduces a door structure of a clothing handling device, which includes a door body 7. The door body 7 is provided with an air guide duct 9. The air guide duct 9 is a hollow channel structure. One end of the air guide duct is flush with the outer edge of the door body 7 and is open, forming an air inlet 12. The other end is in the middle of the door body 7 and is closed. The closed end 702 is provided with an opening facing one side of the door body 7, forming an air outlet 13.

[0056] The air guide duct 9 is generally flat. The closed end 702 of the air guide duct 9 is an arc surface 703 that narrows from the open end to the closed end 702. The side wall of the air guide duct 9 near the door body 7 is formed by an inclined surface that gradually slopes from the outer edge of the door body 7 towards the center of the door body 7 towards the open end. A support plate 14 is provided inside the air guide duct 9 along the airflow direction. The support plate 14 is integrally formed with the air guide duct 9 and is evenly distributed within the air guide duct 9 to enhance the airflow guiding performance of the air guide duct 9. By setting up this air guide duct 9, the airflow from the outlet end of the air duct 5 can be guided, preventing airflow leakage in the gaps of the door structure during its flow, and enhancing the door structure's airflow guiding effect.

[0057] In this embodiment, the door body 7 is a vertically arranged plate structure. A horizontally protruding protrusion 701 is provided on a vertical side of the door body 7 where the air guide duct 9 is provided. 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 guide duct 9; or, the hollow space inside the protrusion 701 constitutes the air guide duct 9.

[0058] Thus, the protrusion 701 on the door body utilizes its own internal hollow space and / or enclosed space to form an air guide duct 9, thereby achieving the technical effect of guiding airflow. Through the above-mentioned arrangement, the installation process of the air guide duct 9 is simplified.

[0059] Meanwhile, in this embodiment, the protrusion 701 can be integrally formed with the door body 7, or the protrusion 701 can be composed of other independent parts that can be detachably installed on the door body 7.

[0060] Preferably, in this embodiment, the air duct 9 is a hollow structure, with one end flush with the outer edge of the door body 7 being open and forming an air inlet 12, and the other end being in the middle of the door body 7 and closed. The closed end 702 is provided with an opening concentric with the door body 7 on the side away from the door body 7, and the opening forms an air outlet 13.

[0061] Preferably, in this embodiment, the air outlet 13 protrudes horizontally outward. By setting the air outlet 13 of the air guide duct 9 to protrude outward, the airflow exiting the air guide duct 9 is guided.

[0062] Example 3

[0063] like Figure 4 As shown, this embodiment introduces a breathable module 8, including a housing 801, which forms a hollow channel. The two ends of the channel are respectively arranged with baffles 803, which divide the two ends of the channel into multiple hollow holes 802. Each hollow hole 802 connects the inside and outside of the channel.

[0064] Through the above configuration, the two sides of the breathable module 8 can be connected through the perforated holes 802 of the two-end connecting channels, so that the airflow on both sides of the breathable module 8 can flow through the channels and achieve the purpose of free exchange of gas flow on both sides under the action of pressure difference; at the same time, by setting multiple perforated holes 802 at intervals at the end of the breathable module 8, the airflow is made to flow evenly under the action of the perforated holes 802, thereby improving the uniformity of the airflow flowing into the roller 2.

[0065] In this embodiment, the perforated holes 802 at both ends of the channel of the breathable module 8 can be arranged in an alternating pattern, so that the airflow does not pass directly through but needs to pass through the folding channel, thereby ensuring that the water entrained in the airflow is intercepted by the folding channel and effectively preventing water from flowing out of the breathable module 8. Of course, in this embodiment, the perforated holes 802 at both ends of the breathable module 8 can also be arranged in any other form, and the above-mentioned inventive objective of the present invention can still be achieved.

[0066] Preferably, in this embodiment, the projections of the perforated holes 802 at both ends of the channel in the same vertical section along the channel axis are at least partially intersecting, so that the channel of the breathable module 8 and the perforated holes 802 at both ends together form a folded gas flow channel, which can effectively intercept the water entrained in the airflow and prevent the water from flowing out of the breathable module 8.

[0067] The cross-section of the ventilation module 8 can be any shape, such as: circle, polygon, ellipse, etc.; preferably, in this embodiment, in order to adapt to the shape of the roller 2, improve ventilation efficiency and improve airflow uniformity, the ventilation module 8 can be set as a disc shape, and the cross-section of the ventilation channel is set as a circle.

[0068] In this embodiment, the two ends of the circular channel are a first end 81 and a second end 82, respectively. Each of the first end 81 and the second end 82 is provided with a baffle 803. The baffle 803 is used to divide the first end 81 and the second end 82 into multiple hollow holes 802, so that the two ends of the channel can exchange airflow with the outside through the arranged hollow holes 802.

[0069] In this embodiment, the channel is a tapered channel with a gradually narrowing radial dimension from the first end 81 to the second end 82. The tapered sidewalls of the channel guide the water flowing into the channel back to the first end 81, effectively preventing water that has accidentally flowed into the channel from accumulating inside. In this embodiment, to achieve the effect of the water trapped in the channel flowing back to the first end 81 and then into the washing machine drum, the first end 81 of the channel needs to face inwards towards the inside of the washing machine drum, and the second end 82 needs to face outwards towards the outside of the washing machine drum. This is necessary to prevent water from flowing out through the vent holes.

[0070] In this embodiment, the inner peripheral wall of the first end 81 of the channel is provided with a plurality of hollow holes 802 arranged at intervals, so that the lowest point of the first end 81 of the channel is a hollow hole 802, thereby ensuring that when the water flow intercepted in the channel flows back to the first end 81 along the conical sidewall, it can flow back to the roller 2 through the hollow hole 802 at the lowest point, and further prevent water accumulation in the channel.

[0071] Preferably, in this embodiment, the breathable module 8 can be integrally formed with the roller 2, or it can be formed separately;

[0072] Preferably, in this embodiment, the outer periphery where the second end 82 of the channel of the breathable module 8 is connected to the channel sidewall is provided with a rounded chamfered surface, so as to prevent problems such as clothing being pinched or scratched by the rounded chamfered surface.

[0073] Example 4

[0074] like Figures 1 to 5 As shown, this embodiment also introduces a clothing processing device, which includes a drum 2 installed inside the outer casing 18, which forms a sealed water container when the washing machine is in the washing state; the drum 2 is provided with at least one of the above-mentioned ventilation modules 8, so as to use the ventilation modules 8 to exchange gases inside and outside the drum 2, thereby achieving the purpose of ventilation and air exchange between the drum 2 and the external air duct 5.

[0075] In this embodiment, at least one ventilation hole equipped with the aforementioned ventilation module 8 is provided at each of the opposite ends of the drum 2. The ventilation holes at both ends of the drum 2 are respectively connected to the air inlet and air outlet of the air duct 5 outside the drum 2. The ventilation module 8 at one end of the drum 2 is connected to the air inlet of the air duct 5; the ventilation module 8 at the other end of the drum 2 is connected to the air outlet of the air duct 5. Thus, in the circulating air path formed by the drum 2 and the air duct 5, a unidirectional circulating airflow is formed under the action of the ventilation modules 8 at different locations, thereby ensuring the normal operation of the drying process. In this embodiment, the end of the drum 2 connected to the air outlet of the air duct 5 is provided with a cylinder opening.

[0076] In this embodiment of the invention, the two opposite ends of the roller 2 are the roller bottom 202 and the roller door 10, respectively. At least one of the above-mentioned ventilation modules 8 are provided on the roller bottom 202 and / or the roller door 10. The ventilation modules 8 at both ends of the roller 2 are respectively connected to the air inlet and air outlet of the air duct 5 outside the roller 2 to achieve the effect of forming a circulating air path.

[0077] In this embodiment, the ventilation module 8 can be integrally formed with the roller 2; of course, the ventilation module 8 can also be installed at the ventilation hole on the roller 2, for example as follows: the housing 801 of the ventilation module 8 is correspondingly covered and assembled in the ventilation hole on the roller 2, and the outer periphery of the housing 801 is sealed and fitted with the inner wall of the ventilation hole; preferably, the housing 801 is sealed and fitted with the inner wall of the ventilation hole; more preferably, the outer periphery of the housing 801 protrudes from the ventilation hole and is in close contact with the roller 2 on the outer periphery of the ventilation hole, thereby improving the assembly stability of the ventilation module 8.

[0078] In this embodiment, the two ends of the channel formed by the housing 801 of the ventilated module 8 are connected to the inside of the roller 2 and the outside of the roller 2, respectively; the first end 81 of the channel of the ventilated module 8 faces the inside of the roller 2 and the second end 82 faces the outside of the roller 2, so as to ensure that the water flowing into the channel is guided by the conical sidewall of the channel and the baffles 803 provided at both ends, so as to achieve the effect of the water accumulated in the ventilated module 8 flowing back to the roller 2.

[0079] Example 5

[0080] like Figures 1-5 As shown, this embodiment introduces a garment processing device. By setting the aforementioned air guide duct 9 on the door 7 of the garment processing device, the air guide duct 9 on the door structure faces the drum opening 201, so as to guide the external airflow into the drum 2 through the air guide duct 9, thereby achieving the technical effect of significantly improving the gas flow during the drying process of the garment processing device; at the same time, by setting the aforementioned air guide duct 9 on the door 7, a significant technical advancement is achieved by using the door 7 to guide the airflow and improve the air intake efficiency of the drum opening 201.

[0081] In this embodiment, the air guide duct 9 is flat in shape, the closed end 702 of the air guide duct 9 is an arc surface 703 that narrows from the open end to the closed end 702, and the side wall of the air guide duct 9 near the door body 7 is composed of an inclined surface that gradually slopes from the outer edge of the door body 7 towards the middle of the door body 7 towards the open.

[0082] Preferably, in this embodiment, the arc surface 703 of the air guide duct 9 is coaxially arranged with the roller 2 to effectively guide the airflow along the axial direction of the roller 2 and into the interior of the roller 2 from the roller opening 201.

[0083] Preferably, in this embodiment, the side wall of the air guide duct 9 near the door 7 is composed of an inclined surface that gradually slopes downwards towards the opening, so as to effectively guide the airflow flowing out of the air guide duct 5 into the interior of the roller 2.

[0084] like Figure 1 As shown, in this embodiment, the roller door 10 is provided with a ventilation module 8 that connects the two sides, and the air outlet 13 of the air duct 9 is set towards the ventilation module 8.

[0085] Preferably, the breathable module 8 can be any breathable structure in the prior art that can achieve air exchange between the inside and outside of the roller 2, such as the breathable module 8 described in the above embodiment.

[0086] In this embodiment, a ventilation module 8 protruding towards the door body 7 is provided at the center of the roller door 10. The ventilation module 8 extends into the air guide 9 from the air outlet 13 and is spaced apart from the inner wall of the air guide 9 to ensure that there is a safe distance between the ventilation module 8 and the air guide 9 during the operation of the roller 2, so as to effectively prevent the occurrence of problems such as mutual collision between the two.

[0087] like Figure 1 As shown, in this embodiment, the outer casing 18 is provided with an outer cylinder 1, and the roller 2 is coaxially fitted inside the outer cylinder 1. An annular window pad 11 is connected between the outer cylinder opening 101 and the outer periphery of the clothing loading port of the outer casing 18. The air guide duct 9 extends from the door body 7 into the space enclosed by the annular window pad 11. The annular window pad 11 is provided with a connector 19 that is opened opposite to the air inlet 12 of the air guide duct 9. The connector 19 is connected to the air outlet of the air duct 5 of the clothing handling device, so that the airflow from the air duct 5 can be guided into the space enclosed by the annular window pad 11 through the connector 19. The air outlet 13 of the air guide duct 9 is opened towards the roller opening 201, so as to achieve the effect of guiding the airflow from the air duct 5 into the air guide duct 9 into the interior of the roller 2. Preferably, in this embodiment, the connector 19 is located above the annular window pad 11 and extends radially along the door body 7.

[0088] Preferably, in this embodiment, when the door 7 is closed, the air inlet 12 of the air guide duct 9 is aligned with and squeezed against the outlet of the connector 19. This ensures that the airflow from the outlet of the air duct 5 into the air guide duct 9 is completely contained and there is no leakage between the air duct 5 and the air guide duct 9.

[0089] Preferably, in this embodiment, the top of the air inlet 12 of the air guide duct 9 is larger than the opening of the connector 19. When the door 7 is closed, the top of the air inlet 12 of the air guide duct 9 covers the opening of the connector 19, which can effectively improve the airflow transmission efficiency.
