Detailed Implementation

[0042] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0043] In the description of this invention, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," and "counterclockwise," 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.

[0044] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0045] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0046] According to an embodiment of the present invention, the clothing processing device can be a dryer. During the processing of clothing, it is necessary to introduce dry airflow into the inner cavity of the clothing processing drum to dry the clothing using the dry airflow.

[0047] In existing technologies, the inner cavity of the garment processing drum only allows for a single airflow. The uneven airflow within the inner cavity of the garment processing drum can cause clothes to adhere to the filter screen during the drying process. When the airflow speed is slow and the direction cannot be controlled, the airflow penetration is also poor, and some areas cannot be effectively dried, affecting the garment processing effect of the garment processing device and impacting the user experience.

[0048] Therefore, this invention provides a clothing treatment device that divides the bottom of the clothing treatment tub 1 into two different air inlet zones to introduce dry airflow into the inner cavity of the clothing treatment tub 1. By controlling whether airflow is introduced through the two different air inlet zones, different clothing treatment effects can be controlled within the inner cavity of the clothing treatment tub 1. This allows the clothing treatment device to select airflows with different drying effects when the clothes are in different states, thereby achieving better clothing treatment results.

[0049] The following is for reference. Figures 1-14 A garment processing apparatus according to an embodiment of the present invention is described.

[0050] The clothing processing device according to an embodiment of the present invention may include: a housing, a clothing processing tub 1, and an air duct housing assembly.

[0051] like Figures 1-8 As shown, the housing of the garment processing device can protect the internal structure of the garment processing device from the outside, so that the garment processing device can maintain stable operation. The garment processing tank 1 is rotatably arranged inside the housing for placing the garments to be processed. The garments are processed in the inner cavity of the garment processing tank 1. The garment processing device dries the garments by passing dry airflow into the inner cavity of the rotating garment processing tank 1. The housing can support and protect the garment processing tank 1 from the outside.

[0052] The bottom of the garment processing tub 1 has a first air inlet zone 11 and a second air inlet zone 12. Airflow can enter the inner cavity of the garment processing tub 1 through the first air inlet zone 11, and airflow can also enter the inner cavity of the garment processing tub 1 through the second air inlet zone 12. Airflow can also enter the inner cavity of the garment processing tub 1 through the first air inlet zone 11 and the second air inlet zone 12 at the same time.

[0053] like Figure 10 and Figure 11 As shown, the first air inlet zone 11 is located in the middle of the bottom of the tub, and the second air inlet zone 12 surrounds the first air inlet zone 11. This not only facilitates the arrangement of the air duct, but also makes the airflow more concentrated when the airflow enters the inner cavity of the clothes processing tub 1 through the first air inlet zone 11, resulting in a faster airflow speed and greater penetrating power. This allows the clothes processing device to quickly dry the parts of the clothes that are difficult to dry in the middle, ensuring the reliable operation of the drying function of the clothes processing device. When the airflow enters the clothes processing tub 1 through both the first air inlet zone 11 and the second air inlet zone 12 at the same time, it ensures that the airflow is evenly distributed throughout the inner cavity of the clothes processing tub 1, so that the clothes in the clothes processing tub 1 can be dried evenly, ensuring the drying effect of the clothes processing device.

[0054] Furthermore, when the airflow enters the inner cavity of the garment processing drum 1 through only the first air inlet zone 11 or the second air inlet zone 12, the airflow velocity is relatively fast, and the penetrating airflow can quickly dry the parts of the garment that are difficult to dry, ensuring that the drying function of the garment processing device can operate reliably and ensuring the drying effect of the garment processing device.

[0055] When the airflow enters the inner cavity of the clothes processing drum 1 through the first air inlet zone 11 and the second air inlet zone 12 at the same time, the airflow in the clothes processing drum 1 is uniform, which can dry the clothes in the inner cavity of the clothes processing drum 1 as a whole. In addition, because the airflow can flow evenly, the phenomenon of clothes adhering to the filter screen during the drying process is avoided, which improves the user experience.

[0056] Furthermore, the air duct shell assembly is located outside the housing, and the air duct shell assembly and the housing define two different air ducts, the first air duct 10 and the second air duct 20. The first air duct 10 and the second air duct 20 are independent of each other and do not interfere with each other. When airflow passes through one air duct, the airflow in that air duct will not enter the other air duct.

[0057] The first air inlet zone 11 connects the first air duct 10 and the inner cavity of the clothing processing tank 1, while the second air inlet zone 12 connects the second air duct 20 and the inner cavity of the clothing processing tank 1. In other words, the airflow entering the clothing processing device from the air inlet can pass through the first air duct 10 and then through the first air inlet zone 11 into the inner cavity of the clothing processing tank 1. Similarly, the airflow entering the clothing processing device from the air inlet can pass through the second air duct 20 and then through the second air inlet zone 12 into the inner cavity of the clothing processing tank 1. By controlling the air ducts through which the airflow passes, the air inlet area within the clothing processing tank 1 can be controlled, thereby enabling the conversion between different gas flow patterns within the inner cavity of the clothing processing tank 1.

[0058] Specifically, the garment processing device has a first ventilation mode and a second ventilation mode. In the first ventilation mode, the first air inlet zone 11 is connected to the first air duct 10 and the inner cavity of the garment processing drum 1. In this ventilation mode, the airflow speed is relatively fast, and the penetrating airflow can quickly dry the parts of the garment that are difficult to dry, ensuring that the drying function of the garment processing device can operate reliably and ensuring the drying effect of the garment processing device.

[0059] In the second ventilation mode, the first air inlet zone 11 connects the first air duct 10 and the inner cavity of the clothes processing tub 1, and the second air inlet zone 12 connects the second air duct 20 and the inner cavity of the clothes processing tub 1. In this ventilation mode, the airflow in the clothes processing tub 1 is uniform, which can dry the clothes in the inner cavity of the clothes processing tub 1 as a whole. In addition, since the airflow can flow uniformly, the phenomenon of clothes adhering to the filter screen during the drying process is avoided, which improves the user experience.

[0060] According to an embodiment of the present invention, the clothing processing device can switch between different ventilation modes and achieve different drying effects by switching ventilation modes, thereby ensuring the drying effect of the clothing processing device, improving the effect of the clothing processing device on clothing processing, and improving the user experience.

[0061] Reference Figure 10 and Figure 11 The inner side of the bottom of the garment processing tub 1 is provided with an air guide 4, which can guide the airflow to flow in different directions to achieve different garment processing effects.

[0062] An air guide hood 4 is located on the inner side of the bottom wall of the garment processing tub 1 to guide the airflow flowing out from the inner side of the bottom wall of the garment processing tub. The air guide hood 4 covers the first air inlet area 11 so that the air guide hood 4 can connect the first air inlet area 11 with the inner cavity of the garment processing tub 1. That is, the airflow in the first air duct 10 enters the air guide hood 4 through the first air inlet area 11 and enters the inner cavity of the garment processing tub 1 through the air guide hood 4. During the process, the airflow can be guided by the air guide hood 4 so that the airflow can achieve different garment processing effects.

[0063] The air guide shroud 4 has multiple ventilation holes, which connect the first air duct 10 and the inner cavity of the clothing processing drum 11. In other words, the airflow in the first air duct 10 enters the air guide shroud 4 through the first air inlet area 11, and then enters the inner cavity of the clothing processing drum 1 through the multiple ventilation holes on the air guide shroud 4. During this process, the airflow is guided by the air guide shroud 4, so that the airflow can flow in different directions and achieve different clothing processing effects.

[0064] like Figure 9 As shown, the air guide 4 protrudes from the inner surface of the bottom wall of the clothing processing tub 1. The protruding air guide 4 can guide the airflow to all sides so that there is airflow throughout the interior of the clothing processing tub 1.

[0065] Furthermore, the air guide shroud 4 has a peripheral wall and a top wall, optionally, such as Figure 12 As shown, multiple ventilation holes are provided on the peripheral wall and the top wall of the air guide hood 4. At this time, the ventilation holes on the top wall can guide the airflow forward, and the ventilation holes on the peripheral wall can guide the airflow around. At this time, there is airflow throughout the interior of the clothing processing tub 1.

[0066] Furthermore, refer to Figure 13 Multiple ventilation holes are provided on the peripheral wall of the air guide shroud 4, while the top wall of the air guide shroud 4 does not have ventilation holes. In this case, the ventilation holes on the peripheral wall can guide the airflow to the surrounding area.

[0067] In other embodiments, such as Figure 14 As shown, multiple ventilation holes are located on the top wall of the air guide shroud 4, while the peripheral wall of the air guide shroud 4 does not have ventilation holes. In this case, the ventilation holes located on the top wall can guide the airflow forward.

[0068] In summary, by selecting different air guide hoods 4, the airflow can be directed in different directions, achieving different air guiding effects, thereby realizing different clothing treatment effects and improving the clothing treatment effect of the clothing treatment device.

[0069] In some optional embodiments, multiple ventilation holes are provided on the peripheral wall and top wall of the air guide hood 4, which can be opened and closed. When all the ventilation holes on the peripheral wall and top wall of the air guide hood 4 are open, the ventilation holes on the top wall can guide the airflow forward, and the ventilation holes on the peripheral wall can guide the airflow to the surroundings. At this time, there is airflow throughout the interior of the clothing processing tub 1.

[0070] When the ventilation holes on the peripheral wall of the air guide shroud 4 are open and the ventilation holes on the top wall of the air guide shroud 4 are closed, the ventilation holes on the peripheral wall can guide the airflow to the surrounding area.

[0071] When the ventilation holes on the top wall of the air guide shroud 4 are open and the ventilation holes on the peripheral wall of the air guide shroud 4 are closed, the ventilation holes on the top wall can guide the airflow forward.

[0072] In summary, by controlling the opening and closing of the ventilation holes on the air guide hood 4, the air guide hood 4 can have different air guiding effects, and can direct the airflow in different directions, thereby achieving different clothing treatment effects and improving the clothing treatment effect of the clothing treatment device.

[0073] Combination Figures 11-14 In the embodiment shown, the air guide hood 4 is formed as a cone shape so that the air guide hood 4 can guide the airflow to different directions, so that the airflow forms wind directions at different angles. And because the cone shape has a concentrating effect, the gas flow velocity through the central vent of the cone shape will increase and have more penetrating power. The airflow can flow to a position further away from the bottom wall of the clothing processing tub 1, thereby achieving a better clothing processing effect.

[0074] like Figures 9-14 As shown, the plurality of ventilation holes include first ventilation holes 411, which are distributed at intervals along the circumference and / or axial direction of the conical shroud on the side wall 41 of the conical shroud. The first ventilation holes 411 distributed at intervals along the circumference and / or axial direction of the conical shroud can guide airflow to the surroundings.

[0075] The plurality of ventilation holes include a second ventilation hole 421 and the second ventilation hole 421 is located at the top 42 of the conical cover. The second ventilation hole 421 located at the top 42 can direct airflow forward.

[0076] In some embodiments, refer to Figure 12 The conical cover is provided with a first ventilation hole 411 distributed at intervals along the circumference and / or axial direction of the conical cover on the side wall 41 of the conical cover and a second ventilation hole 421 provided on the top 42 of the conical cover. The first ventilation hole 411 can guide the airflow to the surrounding area, and the second ventilation hole 421 can guide the airflow to the front. At this time, there is airflow circulating in all parts of the interior of the clothing processing tub 1.

[0077] In other embodiments, such as Figure 13 As shown, the conical cover is provided with first ventilation holes 411 distributed at intervals along the circumference and / or axial direction on the side wall 41 of the conical cover, and the top 42 of the conical cover is not provided with ventilation holes. At this time, the first ventilation holes 411 can guide the airflow to the surroundings.

[0078] In some other embodiments, reference is made to Figure 14 The top 42 of the conical shroud is provided with a second ventilation hole 421, while the sidewalls 41 of the conical shroud are not provided with ventilation holes. In this case, the second ventilation hole 421 can guide the airflow forward.

[0079] In summary, by selecting different conical hoods, the airflow can be directed in different directions, achieving different air guiding effects and thus different garment processing effects, thereby improving the garment processing efficiency of the garment processing device.

[0080] In some optional embodiments, the first ventilation hole 411 and the second ventilation hole 421 are provided on the side wall 41 and the top 42 of the conical cover, which can be opened and closed. When the first ventilation hole 411 and the second ventilation hole 421 are both open, the second ventilation hole 421 can guide the airflow forward, and the first ventilation hole 411 can guide the airflow to the surroundings. At this time, there is airflow throughout the interior of the clothing processing tub 1.

[0081] When the first ventilation hole 411 on the side wall 41 of the conical shroud is open and the second ventilation hole 421 on the top 42 of the conical shroud is closed, the first ventilation hole 411 on the side wall 41 of the conical shroud can guide the airflow to the surroundings.

[0082] When the second ventilation hole 421 located at the top 42 of the conical shroud is open and the first ventilation hole 411 located on the side wall 41 of the conical shroud is closed, the second ventilation hole 421 located at the top 42 of the conical shroud can guide the airflow forward.

[0083] In summary, by controlling the opening and closing of the first ventilation hole 411 and the second ventilation hole 421 on the conical hood, the conical hood can have different air guiding effects and can direct the airflow in different directions, thereby achieving different clothing treatment effects and improving the clothing treatment effect of the clothing treatment device.

[0084] Combination Figures 9-14 In the embodiment shown, the air guide cover 4 also includes a mounting part 43. The air guide cover 4 is mounted on the bottom wall of the clothing processing tub 1 through the mounting part 43, so that the air guide cover 4 can be stably set in the clothing processing device and ensure the stability of the air guide cover 4.

[0085] In some embodiments, the air guide cover 4 is detachably mounted on the bottom wall of the clothing processing tub 1 via the mounting part 43, so as to facilitate the replacement of the air guide cover 4 and to achieve different air guiding effects by replacing the air guide cover 4.

[0086] Optionally, the air guide cover 4 is fixed to the bottom wall of the clothing processing tub 1 by the mounting part 43.

[0087] In other embodiments, the air guide shroud 4 is fixedly mounted on the bottom wall of the clothing processing tub 1 by the mounting part 43.

[0088] Furthermore, the first air inlet zone 11 is provided with a plurality of first air inlets, which are connected to the first air duct 10 and the inner cavity of the clothing processing tub 1. In other words, the airflow in the first air duct 10 can enter the clothing processing tub 1 through the first air inlet on the first air inlet zone 11 on the bottom wall of the clothing processing tub 1.

[0089] The second air intake zone 12 is provided with multiple second air intake holes, which connect the second air duct 20 and the inner cavity of the clothing processing drum 1. In other words, the airflow in the second air duct 20 can enter the inner cavity of the clothing processing drum 1 through the second air intake port 121 opened on the second air intake zone 12 on the bottom wall of the clothing processing drum 1.

[0090] According to some embodiments of the present invention, a plurality of first air inlets are arranged at circumferential intervals along a circumference so that the airflow velocity of the garment processing device entering the garment processing tub 1 through the first air inlet is uniform, so that the airflow effect in the garment processing tub 1 is better.

[0091] The first air inlet is formed into an elongated hole extending circumferentially along the circumference, so that the air outlet area of ​​the first air inlet is larger, thereby increasing the airflow rate entering the clothing processing tank 1 through the first air inlet area 11, thus improving the effect of the clothing processing device on clothing processing.

[0092] Reference Figure 10 and Figure 11Multiple second air inlets are arranged at intervals along the circumference and / or radial direction of the first air inlet area 11, so that the airflow velocity of the clothing processing device entering the clothing processing drum 1 through the second air inlet 121 is uniform, so that the airflow effect in the clothing processing drum 1 is better.

[0093] The flow area of ​​the second air inlet is smaller than that of the first air inlet. Therefore, the airflow rate entering the clothing processing tank 1 through the first air inlet zone 11 is greater than that entering the clothing processing tank 1 through the second air inlet zone 12. This allows more gas to be guided by the air guide hood 4, thereby improving the processing effect of the clothing processing device on the clothing.

[0094] According to some embodiments of the present invention, the garment handling device further includes: a first seal and a second seal. The first seal is disposed between the housing and the bottom of the tub and defines a first transition cavity between the housing and the bottom of the tub. The first transition cavity connects to a first air inlet and a first air duct 10. The second seal is disposed between the housing and the bottom of the tub. The first seal, the second seal, the housing, and the bottom of the tub define a second transition cavity. The second transition cavity connects to a second air inlet and a second air duct 20. The design of the first seal and the second seal ensures the airtightness of the air duct, minimizing airflow loss and improving the user experience of the garment handling device.

[0095] like Figures 1-8 As shown, the air duct shell assembly includes a first cover 2 and a second cover 3, which are disposed outside the housing. A first air duct 10 is defined between the first cover 2 and the housing. The second cover 3 is disposed outside the first cover 2. A second air duct 20 is defined between the second cover 3, the first cover 2, and the housing. In other words, the second cover 3 is fitted outside the first cover 2. A space is formed inside the first cover 2 for airflow. A space is also formed between the first cover 2 and the second cover 3 for airflow. In some embodiments, the two spaces are independent of each other, that is, the airflow passing through the two spaces does not interact.

[0096] In other words, the first air duct 10 and the second air duct 20 are independent of each other and do not interfere with each other. When airflow passes through one air duct, the airflow in that air duct will not enter the other air duct. In this way, the airflow pressure can be increased. For example, when airflow enters the first air duct 10, the airflow entering the first air duct 10 will not enter the second air duct 20. This can prevent the airflow pressure in the first air duct 10 from decreasing, thereby reducing the blowing force on the clothes.

[0097] Both the first air duct 10 and the second air duct 20 are connected to the air inlet and the inner cavity of the clothing processing tub 1. That is to say, air enters the housing through the air inlet and forms an airflow. This airflow can enter the inner cavity of the clothing processing tub 1 through the first air duct 10 and also through the second air duct 20.

[0098] The second cover 3 further defines an air inlet cavity 30 between itself and the outer shell. The air inlet cavity 30 is connected to the inlet 101 of the first air duct 10 and the inlet 201 of the second air duct 20. That is, the air inlet cavity 30 is adapted to connect the inlet 101 of the first air duct 10 and the air inlet, and the inlet 201 of the second air duct 20 and the air inlet. The airflow entering the clothing processing device from the air inlet first enters the air inlet cavity 30, reaches the vicinity of the inlet 101 of the first air duct 10 and the inlet 201 of the second air duct 20 through the air inlet cavity 30, and then enters the inner cavity of the clothing processing drum 1 through the first air duct 10 and / or the second air duct 20.

[0099] Reference Figures 1-8 The garment handling device also includes a switching device 5, which is used to open and close the inlet 201 of the second air duct 20 to control the airflow between the second air duct 20 and the air inlet cavity 30.

[0100] Specifically, the switching device 5 can open and close the inlet 201 of the second air duct 20. When the switching device 5 opens the inlet 201 of the second air duct 20, the airflow can enter the second air duct 20 through the inlet 201 and then enter the inner cavity of the clothing processing drum 1 through the second air duct 20. That is to say, when the switching device 5 opens the inlet 201 of the second air duct 20, the airflow entering the housing through the air inlet can simultaneously enter the inner cavity of the clothing processing drum 1 through the first air duct 10 and the second air duct 20. At this time, since both air ducts in the clothing processing device can provide airflow, the airflow velocity is relatively slow under a fixed gas flow rate.

[0101] Furthermore, when the switching device 5 closes the inlet 201 of the second air duct 20, the airflow cannot enter the second air duct 20 through the inlet 201, and therefore cannot enter the inner cavity of the clothing processing drum 1 through the second air duct 20. In other words, when the switching device 5 closes the inlet 201 of the second air duct 20, the airflow entering the housing through the air inlet can only enter the inner cavity of the clothing processing drum 1 through the first air duct 10. At this time, since there is only one air duct in the clothing processing device that can provide airflow, the airflow velocity is relatively fast under a fixed gas flow rate.

[0102] In other words, the switching device 5 controls the airflow between the second air duct 20 and the air inlet by opening and closing the inlet 201 of the second air duct 20, so that the airflow has different running paths, thereby enabling the garment processing device to switch between different ventilation modes and change the flow rate and flow volume of the airflow during the switching process, so as to better adjust the flow rate and flow volume of the airflow entering the garment processing chamber.

[0103] Reference Figure 7 and Figure 8 The switching device 5 includes at least one switching plate, which can block the flow of air to isolate the air duct. The switching plate is pivotally disposed within the second housing 3. The switching plate can pivot to a position that blocks airflow into the second air duct 20, and it can also pivot to a position that does not block airflow into the second air duct 20. In other words, the switching device 5 switches between an open state and a closed state by pivoting the switching plate.

[0104] In the closed state, the switching plate closes the inlet 201 of the second air duct 20 to isolate the air inlet from the second air duct 20. At this time, the airflow cannot enter the second air duct 20 through the inlet 201, and therefore cannot enter the inner cavity of the clothing processing drum 1 through the second air duct 20. In other words, when the switching device 5 closes the inlet 201 of the second air duct 20, the airflow entering the housing through the air inlet can only enter the inner cavity of the clothing processing drum 1 through the first air duct 10. At this time, since there is only one air duct in the clothing processing device that can provide airflow, the airflow velocity is relatively fast under a fixed gas flow rate.

[0105] In the open state, the switching plate opens the inlet 201 of the second air duct 20 to connect the air inlet and the second air duct 20. Airflow can enter the second air duct 20 through the inlet 201 and then enter the inner cavity of the garment processing drum 1 through the second air duct 20. That is, when the switching device 5 opens the inlet 201 of the second air duct 20, the airflow entering the housing through the air inlet can simultaneously enter the inner cavity of the garment processing drum 1 through the first air duct 10 and the second air duct 20. At this time, since both air ducts in the garment processing device can provide airflow, the airflow velocity is relatively slow under a fixed gas flow rate.

[0106] In other words, by controlling the switching plate to be in different positions, the opening and closing of the inlet 201 of the second air duct 20 can be controlled, thereby controlling the airflow to change its operating path. This allows the garment processing device to switch between different ventilation modes and change the airflow speed and flow rate during the switching process, thereby achieving the purpose of better adjusting the airflow speed and flow rate of the air entering the garment processing chamber.

[0107] like Figure 7 and Figure 8 As shown, the switching plate has a clearance part 53, which prevents the switching plate from affecting the ventilation effect of the first air duct 10. The switching plate can close the inlet 201 of the second air duct 20 when the switching device 5 is closed, and the clearance part 53 can avoid the inlet 101 of the first air duct 10 when the switching device 5 is closed. This ensures that the first air duct 10 can maintain good ventilation and prevents the ventilation effect of the inlet 101 of the first air duct 10 from being affected when the switching plate closes the inlet 201 of the second air duct 20.

[0108] Reference Figure 2 and Figure 6 The switching device 5 also includes a driving component 54, which provides power for the movement of the switching device 5. The driving component 54 is connected to the switching plate and is used to drive the switching plate to swing.

[0109] In some embodiments, the drive component 54 can be a motor, with its motor shaft connected to the switching plate. The rotation of the motor shaft drives the switching plate to swing. Therefore, by controlling the operation of the motor, the position of the switching plate can be controlled, thereby controlling the switching device 5 to switch between the open and closed states. This controls the airflow to change its path, enabling the garment processing device to switch between different ventilation modes and change the airflow velocity and flow rate during the switching process. This achieves the purpose of better adjusting the airflow velocity and flow rate entering the garment processing chamber.

[0110] Combination Figures 1-8 In the embodiment shown, the first cover 2 is located in the middle of the second cover 3, so that the overall structure of the clothing handling device is more reasonable, the widths on both sides of the second air duct 20 are similar, and the ventilation effect is more uniform.

[0111] Furthermore, the switching plate includes two parts, namely a first plate portion 51 and a second plate portion 52, to jointly control the opening and closing of the inlet 201 of the second air duct 20 from both sides, thereby improving the control effect and avoiding the switching plate occupying more installation space, making the overall structure more reasonable. Moreover, the pivot of the first plate portion 51 and the pivot of the second plate portion 52 are located on opposite sides of the second cover 3, making the structure of the second cover 3 more uniform and ensuring that the air resistance on both sides of the cover is the same, thus making the airflow within the second air duct 20 more uniform.

[0112] Optionally, the switching board can be a single switching board to reduce the number of drive components 54, making the overall structure simpler.

[0113] The switching device 5 can be installed at the connection between the second air duct 20 and the flow duct.

[0114] like Figure 4 and Figure 8 As shown, a fan 6 is also installed in the flow duct. The fan 6 can provide power for the flow of air so that the clothing processing device can have a continuous flow of air into the inner cavity of the clothing processing drum 1.

[0115] A volute tongue 7 may also be provided on the inner wall of the second cover 3. The volute tongue 7 is located between the fan 6 and the inlet 201 of the first air duct 10 / second air duct 20 to improve the gas flow effect in the air duct.

[0116] A specific embodiment of the garment processing device is described below with reference to the accompanying drawings.

[0117] The clothing processing device in this embodiment of the invention can be a clothes dryer. The clothes dryer includes a housing, a clothing processing drum 1, a first cover 2, a second cover 3, a switching device 5, an air guide 4, and a fan 6.

[0118] The housing contains a clothing processing tank 1 for holding clothing to be processed. The clothing is processed inside the clothing processing tank 1. An air inlet is provided on the housing. A second cover 3 is located outside the housing, and a certain space is formed between the second cover 3 and the housing. A first cover 2 and a fan 6 are located in the space formed between the second cover 3 and the housing. The fan 6 is located near the air inlet in the space formed between the second cover 3 and the housing so that airflow can be generated in the space formed between the second cover 3 and the housing. The generated airflow flows into the inner cavity of the clothing processing tank 1 along the air inlet cavity 30 defined between the second cover 3 and the housing.

[0119] The first cover 2 is disposed inside the second cover 3 and between the shell and the second cover 3. Thus, the second cover 3, the first cover 2 and the shell together form two air ducts, one inside and one outside. The first air duct 10 is defined between the first cover 2 and the shell, and the second air duct 20 is defined between the second cover 3, the first cover 2 and the shell. The first air duct 10 and the second air duct 20 can connect the air inlet cavity 30 and the inner cavity of the clothing processing tub 1.

[0120] The switching device 5 is located at the connection between the second air duct 20 and the air inlet cavity 30. The switching device 5 includes a motor, a first plate 51, and a second plate 52. One end of the first plate 51 and the second plate 52 are rotatably connected to both sides of the second cover 3 and can swing within the second cover 3 driven by the motor. The switching device 5 achieves switching between an open state and a closed state by swinging the first plate 51 and the second plate 52.

[0121] In the closed state, the first plate 51 and the second plate 52 close the inlet 201 of the second air duct 20 to isolate the air inlet from the second air duct 20. At this time, the airflow cannot enter the second air duct 20 through the inlet 201, and therefore cannot enter the inner cavity of the clothing processing drum 1 through the second air duct 20. That is to say, when the switching device 5 closes the inlet 201 of the second air duct 20, the airflow entering the housing through the air inlet can only enter the inner cavity of the clothing processing drum 1 through the first air duct 10. At this time, since there is only one air duct in the clothing processing device that can provide airflow, the airflow velocity is relatively fast under a fixed gas flow rate.

[0122] In the open state, the first plate 51 and the second plate 52 open the inlet 201 of the second air duct 20 to connect the air inlet and the second air duct 20. Airflow can enter the second air duct 20 through the inlet 201 and then enter the inner cavity of the garment processing drum 1 through the second air duct 20. That is, when the switching device 5 opens the inlet 201 of the second air duct 20, the airflow entering the housing through the air inlet can simultaneously enter the inner cavity of the garment processing drum 1 through the first air duct 10 and the second air duct 20. At this time, since both air ducts in the garment processing device can provide airflow, the airflow velocity is relatively slow under a fixed gas flow rate.

[0123] In other words, by controlling the first plate 51 and the second plate 52 to be in different positions by the motor, the opening and closing of the inlet 201 of the second air duct 20 can be controlled, thereby controlling the airflow to change its running path. This allows the garment processing device to switch between different ventilation modes and change the flow rate and volume of the airflow during the switching process, thereby achieving the purpose of better adjusting the flow rate and volume of the airflow entering the inner cavity of the garment processing drum.

[0124] The bottom wall of the clothing processing tub 1 includes a first air intake zone 11 located in the middle and a second air intake zone 12 surrounding the first air intake zone 11. The first air intake zone 11 is provided with a first air inlet, and the second air intake zone 12 is provided with a second air inlet 121.

[0125] Furthermore, when the airflow enters the inner cavity of the garment processing drum 1 through only the first air inlet zone 11 or the second air inlet zone 12, the airflow velocity is relatively fast, and the penetrating airflow can quickly dry the parts of the garment that are difficult to dry, ensuring that the drying function of the garment processing device can operate reliably and ensuring the drying effect of the garment processing device.

[0126] When the airflow enters the inner cavity of the clothes processing drum 1 through the first air inlet zone 11 and the second air inlet zone 12 at the same time, the airflow in the clothes processing drum 1 is uniform, which can dry the clothes in the inner cavity of the clothes processing drum 1 as a whole. In addition, because the airflow can flow evenly, the phenomenon of clothes adhering to the filter screen during the drying process is avoided, which improves the user experience.

[0127] In some embodiments, the first air inlet is connected to the first air duct 10, and the second air inlet 121 is connected to the second air duct 20.

[0128] An air guide hood 4 is provided on the inner side of the first air inlet zone 11 on the bottom wall of the clothing processing drum 1. The air guide hood 4 is formed into a cone shape and has multiple ventilation holes.

[0129] In some embodiments, there are multiple conical hoods, which are detachably mounted on the bottom wall of the garment processing tub 1 via the mounting part 43. By installing different conical hoods, different air guiding effects can be achieved, thereby achieving different garment processing effects.

[0130] One of the multiple conical hoods has a first ventilation hole 411 that is spaced along the circumference and / or axial direction of the conical hood on the side wall 41 of the conical hood and a second ventilation hole 421 that is located on the top 42 of the conical hood. The first ventilation hole 411 can guide the airflow to the surrounding area, and the second ventilation hole 421 can guide the airflow to the front. At this time, there is airflow circulating in all parts of the interior of the clothing processing drum 1.

[0131] One of the multiple conical hoods has first ventilation holes 411 spaced along the circumferential and / or axial direction on the side wall 41 of the conical hood, while the top 42 of the conical hood does not have ventilation holes. In this case, the first ventilation holes 411 can guide airflow to the surrounding area.

[0132] One of the multiple conical hoods has a second ventilation hole 421 on its top 42, while the sidewalls 41 of the conical hood do not have ventilation holes. In this case, the second ventilation hole 421 can direct airflow forward.

[0133] In summary, by selecting different conical hoods, the airflow can be directed in different directions, achieving different air guiding effects and thus different garment processing effects, thereby improving the garment processing efficiency of the garment processing device.

[0134] In some alternative embodiments, the first ventilation hole 411 and the second ventilation hole 421 are provided on the side wall 41 and the top 42 of the conical cover, which can be opened and closed. When the first ventilation hole 411 and the second ventilation hole 421 are both open, the second ventilation hole 421 can guide the airflow forward, and the first ventilation hole 411 can guide the airflow to the surroundings. At this time, there is airflow circulating throughout the interior of the clothing processing tub 1.

[0135] When the first ventilation hole 411 on the side wall 41 of the conical shroud is open and the second ventilation hole 421 on the top 42 of the conical shroud is closed, the first ventilation hole 411 on the side wall 41 of the conical shroud can guide the airflow to the surroundings.

[0136] When the second ventilation hole 421 located at the top 42 of the conical shroud is open and the first ventilation hole 411 located on the side wall 41 of the conical shroud is closed, the second ventilation hole 421 located at the top 42 of the conical shroud can guide the airflow forward.

[0137] In summary, by controlling the opening and closing of the first ventilation hole 411 and the second ventilation hole 421 on the conical hood, the conical hood can have different air guiding effects and can direct the airflow in different directions, thereby achieving different clothing treatment effects and improving the clothing treatment effect of the clothing treatment device.

[0138] Furthermore, when the switching device 5 closes the inlet 201 of the second air duct 20, the airflow entering the housing through the air inlet can only enter the inner cavity of the clothing processing tub 1 through the first air duct 10. At this time, the conical cover can guide the airflow entering the clothing processing tub 1 from the first air inlet to the periphery of the inner cavity of the clothing processing tub 1, avoiding the disadvantage that there is no airflow at the edge of the inner cavity of the clothing processing tub 1 due to the second air inlet 121 not producing air, thus improving the clothing processing effect of the clothing processing device.
