[0043] The following describes embodiments of the present invention in detail, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and are not to be construed as limiting the present invention.

[0045] 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 the technical features being referred to. Thus, a feature specified as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, "plurality" means at least two, such as two, three, etc., unless otherwise specifically defined.

[0046] In the present invention, unless otherwise expressly specified or limited, a first feature being "above" or "below" a second feature may include the first and second features being in direct contact, or may include the first and second features being in contact not directly but through another feature between them. Furthermore, a first feature being "above," "above," and "above" a second feature may include the first feature being directly above or obliquely above the second feature, or may simply mean that the first feature is higher in level than the second feature. A first feature being "below," "below," and "below" a second feature may include the first feature being directly below or obliquely below the second feature, or may simply mean that the first feature is lower in level than the second feature.

[0047] The clothes treating device according to the embodiment of the present invention may be a clothes dryer. During the clothes treating process, dry airflow needs to be introduced into the inner cavity of the clothes treating tub to dry the clothes using the dry airflow.

[0048] In the prior art, the inner cavity of the clothing treatment barrel only has a single airflow effect, and the airflow in the inner cavity of the clothing treatment barrel is uneven, which will cause the clothes to be adsorbed on the filter net during the drying process. When the airflow velocity is slow and the direction cannot be controlled, it will also lead to poor airflow penetration, and some areas cannot be effectively dried, affecting the effect of the clothing treatment device on the clothes and affecting the user experience.

[0049] To this end, an embodiment of the present invention designs a clothing processing device that divides the bottom of the clothing processing barrel 1 into two different air inlet areas for introducing dry airflow into the inner cavity of the clothing processing barrel 1. By controlling whether the airflow is introduced through the two different air inlet areas, different clothing processing effects can be controlled in the inner cavity of the clothing processing barrel 1, thereby enabling the clothing processing device to select airflows with different drying effects to pass through when the clothes are in different states, thereby achieving better clothing processing effects.

[0050] Reference below Figures 1-14 A clothes treating apparatus according to an embodiment of the present invention is described.

[0051] The laundry processing apparatus according to an embodiment of the present invention may include: a housing, a laundry processing tub 1 and an air duct housing assembly.

[0052] like Figures 1-8 As shown, the shell of the clothing processing device can protect the internal structure of the clothing processing device on the outside so that the clothing processing device can maintain stable operation. A clothing processing barrel 1 is rotatably provided in the shell for placing clothing to be processed. The clothing is processed in the inner cavity of the clothing processing barrel 1. The clothing processing device allows dry airflow to be introduced into the inner cavity of the rotating clothing processing barrel 1 so that the clothing can be dried. The shell can support and protect the clothing processing barrel 1 on the outside of the clothing processing barrel 1.

[0053] Among them, the bottom of the clothing processing barrel 1 has a first air inlet area 11 and a second air inlet area 12. The air flow can enter the inner cavity of the clothing processing barrel 1 through the first air inlet area 11, and the air flow can also enter the inner cavity of the clothing processing barrel 1 through the second air inlet area 12. The air flow can also enter the inner cavity of the clothing processing barrel 1 through the first air inlet area 11 and the second air inlet area 12 at the same time.

[0054] like Figure 10 and Figure 11 As shown, the first air inlet area 11 is arranged in the middle of the bottom of the barrel, and the second air inlet area 12 surrounds the first air inlet area 11. As a result, it is not only convenient for the arrangement of the air duct, but also the airflow is more concentrated when the airflow only passes through the first air inlet area 11 to enter the inner cavity of the clothing treatment barrel 1, so that the airflow velocity is faster and more penetrating, so that the clothing treatment device can quickly dry the part of the middle area of ​​the clothes that is not easy to dry, ensuring that the drying function of the clothing treatment device can operate reliably, and when the airflow enters the clothing treatment barrel 1 through the first air inlet area 11 and the second air inlet area 12 at the same time, it is ensured that the airflow is evenly distributed everywhere in the inner cavity of the clothing treatment barrel 1, so that the clothes in the clothing treatment barrel 1 can be evenly dried, ensuring the drying effect of the clothing treatment device.

[0055] Furthermore, when the air flow enters the inner cavity of the clothing processing barrel 1 only through the first air inlet area 11 or the second air inlet area 12, the air flow rate is faster, and the penetrating air flow can quickly dry the parts of the clothing that are difficult to dry, ensuring that the drying function of the clothing processing device can operate reliably and ensuring the drying effect of the clothing processing device.

[0056] When the air flow enters the inner cavity of the clothing treatment barrel 1 through the first air inlet area 11 and the second air inlet area 12 at the same time, the air flow in the clothing treatment barrel 1 is uniform, and the clothes in the inner cavity of the clothing treatment barrel 1 can be dried as a whole. In addition, since the air flow can flow evenly, the phenomenon of clothes being adsorbed on the filter net during the drying process of the clothing treatment device is avoided, thereby improving the user experience.

[0057] Furthermore, the air duct shell assembly is arranged outside the shell, and two different air ducts, a first air duct 10 and a second air duct 20, are defined between the air duct shell assembly and the shell. The first air duct 10 and the second air duct 20 are independent of each other and do not interfere with each other. When air flows through one of the air ducts, the air flow in the air duct will not enter the other air duct.

[0058] The first air inlet area 11 connects the first air duct 10 and the inner cavity of the laundry tub 1, and the second air inlet area 12 connects the second air duct 20 and the inner cavity of the laundry tub 1. In other words, the airflow entering the laundry treatment device from the air inlet can pass through the first air duct 10 and then through the first air inlet area 11 to enter the inner cavity of the laundry tub 1. The airflow entering the laundry treatment device from the air inlet can pass through the second air duct 20 and then through the second air inlet area 12 to enter the inner cavity of the laundry tub 1. By controlling the air ducts through which the airflow flows, the air inlet area within the laundry tub 1 can be controlled, thereby achieving conversion between different gas flow modes within the inner cavity of the laundry tub 1.

[0059] Specifically, the clothing processing device has a first ventilation mode and a second ventilation mode. In the first ventilation mode, the first air inlet area 11 is connected to the first air duct 10 and the inner cavity of the clothing processing barrel 1. In this ventilation mode, the air flow rate is faster, and the penetrating air flow can quickly dry the parts of the clothing that are difficult to dry, ensuring that the drying function of the clothing processing device can operate reliably and ensuring the drying effect of the clothing processing device.

[0060] In the second ventilation mode, the first air inlet area 11 is connected to the first air duct 10 and the inner cavity of the clothing treatment barrel 1, and the second air inlet area 12 is connected to the second air duct 20 and the inner cavity of the clothing treatment barrel 1. In this ventilation mode, the airflow in the clothing treatment barrel 1 is uniform, and the clothes in the inner cavity of the clothing treatment barrel 1 can be dried as a whole. Moreover, since the airflow can flow evenly, the phenomenon of clothes being adsorbed on the filter net during the drying process of the clothing treatment device is avoided, thereby improving the user experience.

[0061] According to the clothing processing device of an embodiment of the present invention, the clothing processing device can switch between different ventilation modes, and achieve different drying effects through the conversion of 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.

[0062] Reference Figure 10 and Figure 11 An air guide cover 4 is provided on the inner side of the bottom of the laundry treatment barrel 1. The air guide cover 4 can guide the passing airflow so that the airflow flows in different directions to achieve different laundry treatment effects.

[0063] The air guide hood 4 is disposed on the inner side of the bottom wall of the laundry treatment tub 1 to guide the airflow flowing out from the inner side of the laundry treatment tub 1. 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 laundry treatment tub 1. In other words, the airflow in the first air duct 10 enters the air guide hood 4 through the first air inlet area 11, and then enters the inner cavity of the laundry treatment tub 1 through the air guide hood 4. During this process, the airflow can be guided by the air guide hood 4, so that the airflow can achieve different laundry treatment effects.

[0064] The air guide cover 4 is provided with a plurality of ventilation holes, which connect the first air duct 10 with the inner cavity of the clothing treatment barrel 11. That is to say, the airflow in the first air duct 10 enters the air guide cover 4 through the first air inlet area 11, and then enters the inner cavity of the clothing treatment barrel 1 through the plurality of ventilation holes provided on the air guide cover 4. During this process, the airflow will be guided by the air guide cover 4, so that the airflow can flow in different directions, thereby achieving different clothing treatment effects.

[0065] like Figure 9 As shown, the air guide cover 4 protrudes from the inner surface of the bottom wall of the laundry treatment tub 1 . The protruding air guide cover 4 can guide the airflow to all sides so that there is a circulating airflow everywhere inside the laundry treatment tub 1 .

[0066] Furthermore, the air guide cover 4 has a peripheral wall and a top wall, optionally, as Figure 12 As shown, multiple ventilation holes are provided on the peripheral wall and the top wall of the air guide cover 4. At this time, the ventilation holes on the top wall can guide the airflow to the front, and the ventilation holes on the peripheral wall can guide the airflow to the surroundings. At this time, there is circulating airflow everywhere inside the clothing processing barrel 1.

[0067] Further, refer to Figure 13 , multiple ventilation holes are arranged on the peripheral wall of the air guide cover 4, and the top wall of the air guide cover 4 is not provided with ventilation holes. At this time, the ventilation holes located on the peripheral wall can guide the air flow all around.

[0068] In other embodiments, Figure 14 As shown, a plurality of ventilation holes are provided on the top wall of the air guide cover 4, and the peripheral wall of the air guide cover 4 is not provided with ventilation holes. At this time, the ventilation holes on the top wall can guide the air flow to the front.

[0069] In summary, by selecting different air guide covers 4, the air flow can be directed in different directions, different air guiding effects can be achieved, and thus different clothing processing effects are achieved, thereby improving the clothing processing effect of the clothing processing device.

[0070] In some optional embodiments, multiple ventilation holes can be opened and closed on the peripheral wall of the air guide cover 4 and the top wall of the air guide cover 4. When the ventilation holes on the peripheral wall of the air guide cover 4 and the top wall of the air guide cover 4 are all opened, the ventilation holes on the top wall can guide the airflow to the front, and the ventilation holes on the peripheral wall can guide the airflow to the surroundings. At this time, there is airflow circulating everywhere inside the clothing processing barrel 1.

[0071] When the ventilation holes provided on the peripheral wall of the air guide cover 4 are opened and the ventilation holes provided on the top wall of the air guide cover 4 are closed, the ventilation holes located on the peripheral wall can guide the airflow to all sides.

[0072] When the ventilation holes provided on the top wall of the air guide cover 4 are opened and the ventilation holes provided on the peripheral wall of the air guide cover 4 are closed, the ventilation holes located on the top wall can guide the airflow forward.

[0073] To sum up, by controlling the opening and closing of the ventilation holes on the air guide cover 4, the air guide cover 4 can have different air guiding effects and can make the air flow in different directions, thereby achieving different clothing processing effects, thereby improving the clothing processing effect of the clothing processing device.

[0074] Combine Figure 11-14 In the embodiment shown, the air guide cover 4 is formed as a conical cover, so that the air guide cover 4 can guide the airflow to different directions, so that the airflow forms wind directions at different angles, and because the conical cover has a concentrating effect, the gas flow rate passing through the middle vent of the conical cover will increase and be more penetrating, and the airflow can flow to a position farther away from the bottom wall of the clothing treatment barrel 1, thereby achieving a better clothing treatment effect.

[0075] like Figures 9-14 As shown, the multiple ventilation holes include first ventilation holes 411, and the multiple first ventilation holes 411 are distributed on the side wall 41 of the conical cover at intervals along the circumference and / or axial direction of the conical cover. The first ventilation holes 411 distributed at intervals along the circumference and / or axial direction of the conical cover can guide the airflow to all sides.

[0076] The plurality of ventilation holes include a second ventilation hole 421 , and the second ventilation hole 421 is disposed at the top 42 of the conical cover. The second ventilation hole 421 located at the top 42 can direct airflow forward.

[0077] In some embodiments, reference Figure 12 The conical cover is provided with first ventilation holes 411 distributed on the side wall 41 of the conical cover at intervals along the circumference and / or axial direction of the conical cover, and second ventilation holes 421 provided on the top 42 of the conical cover. The first ventilation holes 411 can guide the airflow to the surroundings, and the second ventilation holes 421 can guide the airflow to the front. At this time, there is airflow circulating everywhere inside the clothes processing barrel 1.

[0078] In other embodiments, Figure 13 As shown, the conical cover is provided with first ventilation holes 411 distributed along the circumferential direction and / or axial direction of the conical cover on the side wall 41 of the conical cover, and the top 42 of the conical cover is not provided with ventilation holes. In this case, the first ventilation holes 411 can guide the airflow to the surroundings.

[0079] In some further embodiments, referring to Figure 14 The top 42 of the cone hood is provided with a second ventilation hole 421, and the side wall 41 of the cone hood is not provided with a ventilation hole. In this case, the second ventilation hole 421 can guide the airflow to the front.

[0080] In summary, by selecting different conical covers, the airflow can be directed in different directions, and different wind guiding effects can be achieved, thereby achieving different clothing treatment effects, thereby improving the clothing treatment effect of the clothing treatment device.

[0081] In some optional embodiments, the first ventilation holes 411 and the second ventilation holes 421 can be opened and closed and are arranged on the side wall 41 and the top 42 of the conical cover. When the first ventilation holes 411 and the second ventilation holes 421 are fully opened, the second ventilation holes 421 can direct the airflow to the front, and the first ventilation holes 411 can direct the airflow to the surroundings. At this time, there is circulating airflow everywhere inside the clothing processing barrel 1.

[0082] When the first ventilation holes 411 on the side wall 41 of the conical cover are opened and the second ventilation holes 421 on the top 42 of the conical cover are closed, the first ventilation holes 411 on the side wall 41 of the conical cover can guide the airflow to all sides.

[0083] When the second ventilation holes 421 provided on the top 42 of the conical cover are opened and the first ventilation holes 411 provided on the side wall 41 of the conical cover are closed, the second ventilation holes 421 located on the top 42 of the conical cover can direct the airflow forward.

[0084] To sum up, by controlling the opening and closing of the first ventilation hole 411 and the second ventilation hole 421 on the conical cover, the conical cover can have different wind guiding effects and the airflow can flow in different directions, thereby achieving different clothing processing effects, thereby improving the clothing processing effect of the clothing processing device.

[0085] Combine Figures 9-14 In the embodiment shown, the air guide cover 4 further includes a mounting portion 43 , and the air guide cover 4 is mounted on the bottom wall of the clothing processing tub 1 via the mounting portion 43 , so that the air guide cover 4 can be stably disposed in the clothing processing device, thereby ensuring the stability of the air guide cover 4 .

[0086] In some embodiments, the air guide cover 4 is detachably mounted on the bottom wall of the clothes processing tub 1 through the mounting portion 43 , so as to facilitate replacement of the air guide cover 4 and to achieve different air guide effects by replacing the air guide cover 4 .

[0087] Optionally, the air guide cover 4 is fixed to the bottom wall of the clothes processing tub 1 by snapping together the mounting portion 43 .

[0088] In other embodiments, the air guide cover 4 is fixedly mounted on the bottom wall of the laundry processing tub 1 via the mounting portion 43 .

[0089] Furthermore, the first air inlet area 11 is provided with a plurality of first air inlet holes, which connect the first air duct 10 and the inner cavity of the clothing processing barrel 1. In other words, the airflow in the first air duct 10 can enter the clothing processing barrel 1 through the first air inlet opened on the first air inlet area 11 on the bottom wall of the clothing processing barrel 1.

[0090] The second air inlet area 12 is provided with a plurality of second air inlet holes, which communicate with the second air duct 20 and the inner cavity of the laundry processing tub 1. In other words, the airflow in the second air duct 20 can enter the inner cavity of the laundry processing tub 1 through the second air inlet opening 121 provided in the second air inlet area 12 on the bottom wall of the laundry processing tub 1.

[0091] According to some embodiments of the present invention, multiple first air inlet holes are arranged at circumferential intervals along a circle so that the flow rate of the airflow from the clothing processing device entering the clothing processing barrel 1 through the first air inlet is uniform, so that the airflow in the clothing processing barrel 1 has a better flow effect.

[0092] The first air inlet hole is formed as an elongated hole extending circumferentially along the circumference, so that the air outlet area of ​​the first air inlet is larger, thereby increasing the air flow rate entering the clothing processing barrel 1 through the first air inlet area 11, thereby improving the effect of the clothing processing device on clothing processing.

[0093] Reference Figure 10 and Figure 11, multiple second air inlet holes are arranged at intervals along the circumferential and / or radial directions of the first air inlet area 11, so that the flow rate of the airflow from the clothing processing device into the clothing processing barrel 1 through the second air inlet 121 is uniform, so that the flow effect of the airflow in the clothing processing barrel 1 is better.

[0094] The flow area of ​​the second air inlet hole is smaller than the flow area of ​​the first air inlet hole. Therefore, the air flow rate entering the clothing processing barrel 1 through the first air inlet area 11 is larger than the air flow rate entering the clothing processing barrel 1 through the second air inlet area 12, so that more gas can be guided by the air guide cover 4, thereby improving the treatment effect of the clothing treatment device on the clothing.

[0095] According to some embodiments of the present invention, the clothing processing device further includes: a first seal and a second seal, the first seal being arranged between the shell and the bottom of the barrel and defining a first transition cavity between the shell and the bottom of the barrel, the first transition cavity being connected to the first air inlet and the first air duct 10, the second seal being arranged between the shell and the bottom of the barrel, the first seal, the second seal, the shell and the bottom of the barrel defining a second transition cavity, the second transition cavity being connected to the second air inlet and the second air duct 20, the design of the first seal and the second seal can ensure the sealing of the air duct, so that the air volume loss is as small as possible, thereby improving the user experience of the clothing processing device.

[0096] like Figures 1-8 As shown, the air duct shell assembly includes: a first cover body 2 and a second cover body 3, and the first cover body 2 and the second cover body 3 are arranged outside the shell. A first air duct 10 is defined between the first cover body 2 and the shell, and the second cover body 3 is covered on the outside of the first cover body 2. A second air duct 20 is defined between the second cover body 3, the first cover body 2 and the shell. In other words, the second cover body 3 is sleeved on the outside of the first cover body 2, and a space is formed inside the first cover body 2 for the passage of airflow. A space is also formed between the first cover body 2 and the second cover body 3 for the passage of airflow. In addition, in some embodiments, the two spaces are independent of each other, that is, the airflow passing through the two spaces will not interact.

[0097] 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 air flows through one air duct, the air in that air duct will not enter the other air duct. This can increase the pressure of the air flow. For example, if the air flows into the first air duct 10, the air flow entering the first air duct 10 will not enter the second air duct 20. This can prevent the air flow pressure in the first air duct 10 from decreasing, thereby reducing the blowing force on the clothes.

[0098] The first air duct 10 and the second air duct 20 are both connected to the air inlet and the inner cavity of the clothing treatment tub 1, that is, air enters the shell through the air inlet and forms an airflow, which can enter the inner cavity of the clothing treatment tub 1 through the first air duct 10 and can also enter the inner cavity of the clothing treatment tub 1 through the second air duct 20.

[0099] An air inlet cavity 30 is further defined between the second cover 3 and the housing. The air inlet cavity 30 is in communication with the inlet 101 of the first air duct 10 and the inlet 201 of the second air duct 20. In other words, the air inlet cavity 30 is adapted to communicate between the inlet 101 of the first air duct 10 and the air inlet, and between the inlet 201 of the second air duct 20 and the air inlet. Airflow entering the laundry processing device from the air inlet first enters the air inlet cavity 30, passes through 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, and then passes through the first air duct 10 and / or the second air duct 20 into the inner cavity of the laundry processing tub 1.

[0100] Reference Figures 1-8 The clothing processing device further includes: a switching device 5, which is used to open and close the inlet 201 of the second air duct 20 to control the air flow between the second air duct 20 and the air inlet cavity 30.

[0101] 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, air flow can enter the second air duct 20 through the inlet 201 of the second air duct 20, and then enter the inner cavity of the laundry processing tub 1 through the second air duct 20. In other words, when the switching device 5 opens the inlet 201 of the second air duct 20, air flow entering the housing through the air inlet can simultaneously enter the inner cavity of the laundry processing tub 1 through the first air duct 10 and the second air duct 20. At this time, since both air ducts in the laundry processing device can provide air flow, the flow rate of the air flow is relatively slow under the condition of a fixed gas flow rate.

[0102] 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 of the second air duct 20, and thus cannot enter the inner cavity of the laundry processing tub 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 laundry processing tub 1 through the first air duct 10. At this time, since there is only one air duct in the laundry processing device that can provide airflow, the airflow rate is relatively fast under the condition of a fixed gas flow rate.

[0103] That is to say, 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 clothing processing device to switch between different ventilation modes and change the flow rate and flow of the airflow during the switching process, so as to achieve the purpose of better adjusting the flow rate and flow of the airflow entering the clothing processing chamber.

[0104] Reference Figure 7 and Figure 8 The switching device 5 includes at least one switching plate capable of blocking airflow to isolate the air duct. The switching plate is swingably disposed within the second housing 3. The switching plate can swing to a position that blocks airflow into the second air duct 20, or to a position that prevents airflow from entering the second air duct 20. In other words, the switching device 5 switches between an open state and a closed state by swinging the switching plate.

[0105] 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 of the second air duct 20, and thus cannot enter the inner cavity of the laundry processing tub 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 laundry processing tub 1 through the first air duct 10. At this time, since there is only one air duct in the laundry processing device that can provide airflow, the airflow rate is relatively fast under the condition of a fixed gas flow rate.

[0106] 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 of the second air duct 20 and then enter the inner cavity of the laundry processing tub 1 through the second air duct 20. In other words, when the switching device 5 opens the inlet 201 of the second air duct 20, airflow entering the housing through the air inlet can simultaneously enter the inner cavity of the laundry processing tub 1 through the first air duct 10 and the second air duct 20. At this time, since both air ducts in the laundry processing device can provide airflow, the flow rate of the airflow is relatively slow under the condition of a fixed gas flow rate.

[0107] That is to say, by controlling the switching plate to be located 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 running path, and then enabling the clothing processing device to switch between different ventilation modes, and change the flow rate and flow of the airflow during the conversion process, so as to achieve the purpose of better adjusting the flow rate and flow of the airflow entering the clothing processing chamber.

[0108] like Figure 7 and Figure 8 As shown, the switching plate has a relief portion 53. This relief portion 53 prevents the switching plate from affecting the ventilation 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 in the off state. The relief portion 53 avoids the inlet 101 of the first air duct 10 when the switching device 5 is in the off state. This ensures that the first air duct 10 maintains a good ventilation state, preventing the switching plate from affecting the ventilation of the inlet 101 of the first air duct 10 when closing the inlet 201 of the second air duct 20.

[0109] Reference Figure 2 and Figure 6 The switching device 5 further includes: a driving component 54, which can provide power for the movement of the switching device 5, wherein the driving component 54 is connected to the switching plate to drive the switching plate to swing.

[0110] In some embodiments, the driving component 54 can be a motor, the motor shaft of which is connected to the switching plate, and 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, and the switching device 5 can be controlled to switch between the open state and the closed state, thereby controlling the airflow to change the running path, thereby enabling the clothing processing device to switch between different ventilation modes. During the switching process, the flow rate and flow rate of the airflow are changed, thereby achieving the purpose of better adjusting the flow rate and flow rate of the airflow entering the clothing processing chamber.

[0111] Combine Figures 1-8 In the illustrated embodiment, the first cover 2 is disposed in the middle of the second cover 3 to make the overall structure of the clothing processing device more reasonable, and to make the widths of both sides of the second air duct 20 similar, resulting in a more uniform ventilation effect.

[0112] Furthermore, the switch plate includes two portions, a first plate portion 51 and a second plate portion 52, which together control the opening and closing of the inlet 201 of the second air duct 20 from both sides. This improves control effectiveness, avoids the switch plate from occupying additional installation space, and improves the overall structure. Furthermore, the rotation axis of the first plate portion 51 and the rotation axis 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, ensuring equal wind resistance on both sides of the cover, and thus more uniform airflow within the second air duct 20.

[0113] Optionally, the switching plate may be a single switching plate to reduce the number of driving components 54 and make the overall structure more concise.

[0114] The switching device 5 may be provided at the connection between the second air duct 20 and the overflow air duct.

[0115] like Figure 4 and Figure 8 As shown, a fan 6 is further provided in the flow duct, and the fan 6 can provide power for the flow of air, so that a continuous air flow can enter the inner cavity of the clothes processing tub 1 in the clothes processing device.

[0116] 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 / the second air duct 20 to improve the gas flow effect in the air duct.

[0117] A specific embodiment of the clothes treating device will be described below with reference to the accompanying drawings.

[0118] The clothes processing device of the embodiment of the present invention may be a clothes dryer, which includes a housing, a clothes processing tub 1 , a first cover 2 , a second cover 3 , a switching device 5 , an air guide 4 , and a fan 6 .

[0119] Among them, a clothing processing barrel 1 is provided in the shell for placing clothing to be processed. The clothing is processed in the inner cavity of the clothing processing barrel 1. An air inlet is provided on the shell, and the second cover body 3 is provided outside the shell. A certain space is formed between the second cover body 3 and the shell. The first cover body 2 and the fan 6 are provided in the space formed between the second cover body 3 and the shell, wherein the fan 6 is provided in the space formed between the second cover body 3 and the shell near the air inlet so that an airflow can be formed in the space formed by the second cover body 3 and the shell, and the formed airflow flows along the air inlet cavity 30 defined between the second cover body 3 and the shell to the inner cavity of the clothing processing barrel 1.

[0120] The first cover body 2 is arranged inside the second cover body 3 and between the shell and the second cover body 3. Thus, the second cover body 3, the first cover body 2 and the shell together form two inner and outer air ducts, wherein a first air duct 10 is defined between the first cover body 2 and the shell, and a second air duct 20 is defined between the second cover body 3, the first cover body 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 barrel 1.

[0121] The switching device 5 is disposed at the connection between the second air duct 20 and the air inlet chamber 30. The switching device 5 includes a motor, a first plate portion 51, and a second plate portion 52. One end of the first plate portion 51 and the second plate portion 52 are rotatably connected to opposite sides of the second cover 3 and can be driven by the motor to swing within the second cover 3. The switching device 5 switches between an open state and a closed state by the swinging of the first plate portion 51 and the second plate portion 52.

[0122] In the closed state, the first plate portion 51 and the second plate portion 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 of the second air duct 20, and thus cannot enter the inner cavity of the laundry treatment tub 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 laundry treatment tub 1 through the first air duct 10. At this time, since there is only one air duct in the laundry treatment device that can provide airflow, the airflow rate is relatively fast under the condition of a fixed gas flow rate.

[0123] In the open state, the first plate portion 51 and the second plate portion 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 of the second air duct 20 and then enter the inner cavity of the laundry treatment tub 1 through the second air duct 20. In other words, when the switching device 5 opens the inlet 201 of the second air duct 20, airflow entering the housing through the air inlet can simultaneously enter the inner cavity of the laundry treatment tub 1 through the first air duct 10 and the second air duct 20. At this time, since both air ducts in the laundry treatment device can provide airflow, the flow rate of the airflow is relatively slow under the condition of a fixed gas flow rate.

[0124] That is to say, by controlling the first plate 51 and the second plate 52 to be located at 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 change of the airflow running path, and then enabling the clothing processing device to switch between different ventilation modes, and change the flow rate and flow of the airflow during the conversion process, so as to achieve the purpose of better adjusting the flow rate and flow of the airflow entering the inner cavity of the clothing processing barrel.

[0125] The bottom wall of the laundry treatment tub 1 includes a first air inlet area 11 in the middle and a second air inlet area 12 surrounding the first air inlet area 11 . The first air inlet area 11 is provided with a first air inlet, and the second air inlet area 12 is provided with a second air inlet 121 .

[0126] Furthermore, when the air flow enters the inner cavity of the clothing processing barrel 1 only through the first air inlet area 11 or the second air inlet area 12, the air flow rate is faster, and the penetrating air flow can quickly dry the parts of the clothing that are difficult to dry, ensuring that the drying function of the clothing processing device can operate reliably and ensuring the drying effect of the clothing processing device.

[0127] When the air flow enters the inner cavity of the clothing treatment barrel 1 through the first air inlet area 11 and the second air inlet area 12 at the same time, the air flow in the clothing treatment barrel 1 is uniform, and the clothes in the inner cavity of the clothing treatment barrel 1 can be dried as a whole. In addition, since the air flow can flow evenly, the phenomenon of clothes being adsorbed on the filter net during the drying process of the clothing treatment device is avoided, thereby improving the user experience.

[0128] 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 .

[0129] An air guide cover 4 is provided on the inner side of the first air inlet area 11 on the bottom wall of the laundry treatment tub 1 . The air guide cover 4 is formed into a cone-shaped cover with a plurality of ventilation holes formed thereon.

[0130] In some embodiments, there are multiple conical covers, which are detachably mounted on the bottom wall of the clothing processing barrel 1 through the mounting portion 43. By installing different conical covers, different air guiding effects can be achieved, thereby achieving different clothing processing effects.

[0131] One of the multiple conical covers is provided with a first ventilation hole 411 distributed on the side wall 41 of the conical cover at intervals along the circumference and / or axial direction of the conical cover, and a second ventilation hole 421 is provided on the top 42 of the conical cover. The first ventilation hole 411 can guide the airflow to the surroundings, and the second ventilation hole 421 can guide the airflow to the front. At this time, there is airflow circulating everywhere inside the clothing processing barrel 1.

[0132] One of the multiple conical covers is provided with first ventilation holes 411 spaced apart along the circumferential and / or axial directions of the conical cover on the sidewall 41 of the conical cover, and no ventilation holes are provided on the top 42 of the conical cover. In this case, the first ventilation holes 411 can direct airflow in all directions.

[0133] The top 42 of one of the plurality of conical covers is provided with a second ventilation hole 421, and the side wall 41 of the conical cover is not provided with a ventilation hole. In this case, the second ventilation hole 421 can guide the airflow forward.

[0134] In summary, by selecting different conical covers, the airflow can be directed in different directions, and different wind guiding effects can be achieved, thereby achieving different clothing treatment effects, thereby improving the clothing treatment effect of the clothing treatment device.

[0135] In other optional embodiments, the first ventilation holes 411 and the second ventilation holes 421 can be opened and closed and are arranged on the side wall 41 and the top 42 of the conical cover. When the first ventilation holes 411 and the second ventilation holes 421 are fully opened, the second ventilation holes 421 can direct the airflow to the front, and the first ventilation holes 411 can direct the airflow to the surroundings. At this time, there is circulating airflow everywhere inside the clothing processing barrel 1.

[0136] When the first ventilation holes 411 on the side wall 41 of the conical cover are opened and the second ventilation holes 421 on the top 42 of the conical cover are closed, the first ventilation holes 411 on the side wall 41 of the conical cover can guide the airflow to all sides.

[0137] When the second ventilation holes 421 provided on the top 42 of the conical cover are opened and the first ventilation holes 411 provided on the side wall 41 of the conical cover are closed, the second ventilation holes 421 located on the top 42 of the conical cover can direct the airflow forward.

[0138] To sum up, by controlling the opening and closing of the first ventilation hole 411 and the second ventilation hole 421 on the conical cover, the conical cover can have different wind guiding effects and the airflow can flow in different directions, thereby achieving different clothing processing effects, thereby improving the clothing processing effect of the clothing processing device.

[0139] Moreover, when the switching device 5 closes the inlet 201 of the second air duct 20, the air flow entering the shell through the air inlet can only enter the inner cavity of the clothing treatment tub 1 through the first air duct 10. At this time, the conical cover can guide the air flow entering the clothing treatment tub 1 from the first air inlet to the four sides of the inner cavity of the clothing treatment tub 1, avoiding the disadvantage of no air flow at the edge of the inner cavity of the clothing treatment tub 1 due to the lack of air from the second air inlet 121, thereby improving the clothing treatment effect of the clothing treatment device.
