The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0048] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0049] In the present invention, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them.

[0050] The ventilation assembly according to the embodiment of the present invention can be used in a clothing treatment device, which can be a clothes dryer. The clothing treatment device allows the clothes to be dried by introducing dry air into the inner cavity of the clothing treatment barrel. Specifically, the clothing treatment device includes a clothing treatment barrel, which defines a clothing treatment cavity, in which the clothes to be treated are placed, and the clothes are treated in the clothing treatment cavity. During the process of treating the clothes, it is necessary to introduce dry air into the clothing treatment cavity through the air duct defined by the ventilation assembly located at the rear side of the clothing treatment cavity, so as to dry the clothes using the dry air.

[0051] A traditional clothing processing device has only one air duct with a fixed shape for introducing dry airflow into the clothing processing chamber. Since the shape of the air inlet channel of the clothing processing device is fixed, the clothing processing device can only adjust the flow rate and flow rate of the airflow entering the clothing processing chamber by a fan. The flow rate and flow rate control process of the dry airflow in the clothing processing chamber is complicated. In addition, the direction in which the dry airflow enters the clothing processing chamber and the air inlet position are fixed. There may be dead corners in the clothing processing process, and the uniformity of drying clothes is poor, which affects the effect of the clothing processing device on clothing processing and affects the user experience.

[0052] To this end, an embodiment of the present invention designs a ventilation component having multiple different air ducts for introducing dry airflow to different positions in the clothing processing chamber 061, and the switching device 3 can control whether airflow is introduced into one of the air ducts. Therefore, by controlling the switching device 3, the airflow can have different running paths, thereby enabling the clothing processing device 1000 to switch between different ventilation modes and change the flow rate and flow rate of the airflow during the switching process, so as to better adjust the flow rate and flow rate of the airflow entering the clothing processing chamber 061 and the distribution of the airflow in the clothing processing chamber 061.

[0053] Reference below Figure 1-Figure 12 A vent assembly according to an embodiment of the present invention is described.

[0054] The ventilation assembly according to the embodiment of the present invention may include: a wind shield 4 , an air duct shell 10 and a switching device 3 .

[0055] Among them, an air inlet cavity 024 and an air outlet cavity are defined between the air duct shell 10 and the wind shield plate 4, and the air outlet cavity includes a first air duct 021, a second air duct 022 and a third air duct 023, and the third air duct 023 is located between the first air duct 021 and the second air duct 022, wherein the first air duct 021 and the second air duct 022 are independent of each other, and the downstream ends in the air flow direction are not connected, and the air flow direction in the air duct is consistent, thereby avoiding the airflow collision in the first air duct 021 and the second air duct 022, and avoiding the air volume loss caused by the airflow collision process.

[0056] The wind shield 4 has a first air outlet 041, a second air outlet 042 and a third air outlet 043, and the third air outlet 043 is also located between the first air outlet 041 and the second air outlet 042, wherein the first air duct 021 corresponds to the first air outlet 041, and the first air duct 021 connects the first air outlet 041 and the air inlet cavity 024, the second air duct 022 corresponds to the second air outlet 042, and the second air duct 022 connects the second air outlet 042 and the air inlet cavity 024, and the third air duct 023 corresponds to the third air outlet 043, and the third air duct 023 connects the third air outlet 043 and the air inlet cavity 024.

[0057] That is to say, the airflow entering the ventilation component first enters the air inlet chamber 024, and is divided at the inlets of the first air duct 021, the second air duct 022 and the third air duct 023. One part passes through the first air duct 021 and flows out through the first air outlet 041, another part passes through the second air duct 022 and flows out through the second air outlet 042, and another part passes through the third air duct 023 and flows out through the third air outlet 043. The first air outlet 041, the second air outlet 042 and the third air outlet 043 can correspond to the air inlets at different positions in the clothing processing chamber 061. By controlling the airflow velocity and flow rate in the first air duct 021, the second air duct 022 and the third air duct 023, the airflow velocity, flow rate and distribution of the airflow in the clothing processing chamber 061 can be controlled.

[0058] Furthermore, the switching device 3 is disposed on the air duct housing 10 , and is used to open and close the inlet of the third air duct 023 to control the interruption of air flow between the third air duct 023 and the air inlet cavity 024 .

[0059] When the switching device 3 opens the inlet of the third air duct 023 to control the connection between the third air duct 023 and the air inlet chamber 024, the air flow in the air inlet chamber 024 can flow to the clothing processing chamber 061 through the first air duct 021, the second air duct 022 and the third air duct 023 at the same time, and the overall flow rate and flow velocity in the air duct are controlled by the wind wheel 300. The air inlets corresponding to the first air outlet 041, the second air outlet 042 and the third air outlet 043 in the clothing processing chamber 061 all take air into the clothing processing chamber 061, and there is air outlet in all directions in the clothing processing chamber 061, and the drying effect is uniform.

[0060] When the switching device 3 closes the inlet of the third air duct 023 to control the disconnection between the third air duct 023 and the air inlet chamber 024, the air flow in the air inlet chamber 024 can only flow to the clothing processing chamber 061 through the first air duct 021 and the second air duct 022, and the overall flow in the air duct remains unchanged, while the air flow velocity in the first air duct 021 and the second air duct 022 increases, and the flow rate increases. In addition, only the air inlets corresponding to the first air outlet 041 and the second air outlet 042 enter the clothing processing chamber 061. The air flow velocity in the space corresponding to the first air outlet 041 in the clothing processing chamber 061 is fast, the air volume is distributed more, and the drying speed of this part is faster.

[0061] When the wind wheel speed is constant, that is, the overall gas flow rate remains unchanged, when the switching device 3 opens the inlet of the third air duct 023, since the three air ducts in the clothing processing device 1000 can provide air circulation, the flow rate of the air flow is relatively slow. When the switching device 3 closes the inlet of the third air duct 023, since only two air ducts in the clothing processing device 1000 can provide air circulation, the flow rate of the air flow is relatively fast. That is to say, the switching device 3 opens and closes the inlet of the third air duct 023 to make the air flow have different running paths, thereby enabling the clothing processing device 1000 to switch between different ventilation modes and change the flow rate and flow rate of the air flow during the switching process, so as to achieve the purpose of better adjusting the flow rate and flow rate of the air flow entering the clothing processing chamber 061.

[0062] The airflow can be delivered to different positions in the clothing processing chamber 061 through the first air duct 021, the second air duct 022 and the third air duct 023. Controlling the on and off of the third air duct 023 can control the distribution of the airflow in the clothing processing chamber 061 and the direction of the airflow flowing in the clothing processing chamber 061. The switching device 3 provides conditions for the clothing processing device 1000 to realize a variety of different ventilation modes and switch between different ventilation modes. The clothing processing device 1000 can switch between different ventilation modes according to different drying states, thereby improving the effect of the clothing processing device 1000 on clothing processing and improving the user experience.

[0063] According to the ventilation component of the embodiment of the present invention, the ventilation component defines a plurality of independent air ducts, and through the switching device 3, the airflow has different running paths, so that the clothing processing device 1000 can switch between different ventilation modes, and better adjust the flow rate and flow rate of the airflow entering the clothing processing chamber 061 and the distribution of the airflow in the clothing processing chamber 061.

[0064] like Figure 3 As shown, the air inlet chamber 024 and the air outlet chamber are arranged in the first direction, and the first air duct 021, the third air duct 023 and the second air duct 022 are arranged side by side in the second direction intersecting the first direction. That is to say, the first air duct 021, the third air duct 023 and the second air duct 022 extend along the first direction, and the first air duct 021, the third air duct 023 and the second air duct 022 are sequentially arranged in the second direction, and the airflow in the air inlet chamber 024 flows along the first direction and is split at the inlet of the air duct. When the inlet of the third air duct 023 is closed by the switching device 3, part of the airflow flowing along the first direction is blocked by the switching device 3, flows in the second direction, and flows into the clothing processing chamber 061 through the first air duct 021 and the second air duct 022 respectively when flowing through the inlets of the first air duct 021 and the second air duct 022.

[0065] Reference Figure 3 The air duct shell 10 includes: a cover shell and two partitions 21, the two partitions 21 are arranged at intervals in the cover shell and each partition 21 is connected to the bottom wall of the cover shell, the partition 21 extends along a first direction, and the two partitions 21 are arranged at intervals in a second direction, wherein the third air duct 023 is located between the two partitions 21, the first air duct 021 is located between one of the partitions 21 and the side wall of the cover shell, and the second air duct 022 is located between the other partition 21 and the side wall of the cover shell.

[0066] A first air duct 021 is defined between one of the partitions 21 and the side wall of the housing, a second air duct 022 is defined between the other partition 21 and the side wall of the housing, and a third air duct 023 is defined between the two partitions 21. That is, the partition 21 divides a complete air duct defined by the housing into a plurality of air ducts, and the plurality of air ducts correspond to different positions on the plane of the bottom wall of the housing, respectively. The airflow can be transported to different positions in the clothing processing chamber 061 through the first air duct 021, the second air duct 022 and the third air duct 023. Controlling the on and off of the third air duct 023 can control the distribution of the airflow in the clothing processing chamber 061 and the direction of the airflow flowing in the clothing processing chamber 061, which provides conditions for the clothing processing device 1000 to realize a plurality of different ventilation modes and switch between different ventilation modes. The clothing processing device 1000 can switch different ventilation modes according to different drying states, thereby improving the effect of the clothing processing device 1000 on clothing processing and improving the user experience.

[0067] The partition 21 can separate the third air duct 023 from the first air duct 021 and the second air duct 022, ensuring that the first air duct 021, the second air duct 022 and the third air duct 023 are independent of each other, and preventing the airflow from entering the third air duct 023 through the gap between the air ducts when the switching device 3 closes the inlet of the third air duct 023. The partition 21 has a reinforcement portion, which can increase the structural strength of the partition 21, ensuring that the partition 21 has sufficient strength to resist the pressure on the partition 21 caused by the airflow during the flow of the air, and ensuring that the partition 21 has sufficient stability and reliability under any working conditions.

[0068] Reference Figure 3 The first end of each partition 21 in the length direction is connected to the side wall of the shell, thereby, the space defined by the shell is divided into three independent and parallel cavities by the two partitions 21, which are formed into air ducts accordingly. The inlet of the first air duct 021 is located between the second end of one of the partitions 21 in the length direction and the side wall of the shell, the inlet of the second air duct 022 is located between the second end of the other partition 21 in the length direction and the side wall of the shell, and the inlet of the third air duct 023 is located between the second ends of the two partitions 21 in the length direction. The two partitions 21 can divide the airflow flowing from the air inlet chamber 024 to the clothing processing chamber 061 into three parts. After the airflow is diverted, it flows from the second end of the partition 21 in the length direction to one end of the partition 21 in the length direction under the guidance of the partition 21, and flows into the clothing processing chamber 061.

[0069] like Figure 3 As shown, the air inlet chamber 024 is used to install the wind wheel 300, and the wind wheel 300 can provide power for the flow of airflow, so that the airflow can continuously enter the first air duct 021, the second air duct 022 and the third air duct 023 from the air inlet chamber 024, and flow into the clothing processing chamber 061 from the ventilation component. The side wall of the housing is provided with a volute tongue 23 and the volute tongue 23 is located between the wind wheel 300 and the air outlet chamber to improve the gas flow effect in the air duct. At least a part of the two partitions 21 extends in a direction close to the volute tongue 23 toward a direction close to each other to reduce the wind resistance in the air duct and avoid the loss of air volume during the air flow through the air duct.

[0070] Combination Figure 1 and Figure 4In the illustrated embodiment, the wind shield 4 has a first air outlet area 41 corresponding to the position of the first air duct 021, a second air outlet area 42 corresponding to the position of the second air duct 022, and a third air outlet area 43 corresponding to the position of the third air duct 023. The first air outlet portion 041 is arranged in the first air outlet area 41, the second air outlet portion 042 is arranged in the second air outlet area 42, and the third air outlet portion 043 is arranged in the third air outlet area 43. The airflow flowing through the first air duct 021 will flow into the clothing processing chamber 061 through the first air outlet portion 041 located in the first air outlet area 41, the airflow flowing through the second air duct 022 will flow into the clothing processing chamber 061 through the second air outlet portion 042 located in the second air outlet area 42, and the airflow flowing through the third air duct 023 will flow into the clothing processing chamber 061 through the third air outlet portion 043 located in the third air outlet area 43.

[0071] Furthermore, the wind shield 4 also has a fourth air outlet area 44, which corresponds to a portion of the air inlet cavity 024 close to the air outlet cavity. The fourth air outlet area 44 is provided with a fourth air outlet portion 044 connected to the air inlet cavity 024. Part of the airflow in the air inlet cavity 024 will directly flow into the clothing processing cavity 061 through the fourth air outlet portion 044 located in the fourth air outlet area 44, and this part of the airflow does not pass through the air outlet cavity.

[0072] That is to say, part of the airflow in the air inlet chamber 024 flows directly into the clothing processing chamber 061 through the fourth air outlet portion 044 located in the fourth air outlet area 44, and the remaining part of the airflow passes through the inlets of the first air duct 021, the second air duct 022 and the third air duct 023, and is divided at the inlets of the first air duct 021, the second air duct 022 and the third air duct 023, and flows into the clothing processing chamber 061 through the first air duct 021, the second air duct 022 and the third air duct 023 respectively, wherein the airflow flowing through the first air duct 021 will flow into the clothing processing chamber 061 through the first air outlet portion 041 located in the first air outlet area 41, the airflow flowing through the second air duct 022 will flow into the clothing processing chamber 061 through the second air outlet portion 042 located in the second air outlet area 42, and the airflow flowing through the third air duct 023 will flow into the clothing processing chamber 061 through the third air outlet portion 043 located in the third air outlet area 43.

[0073] Since the switching device 3 is arranged at the entrance of the third air duct 023, the switching device 3 can only control the air flow interruption between the third air outlet 043 corresponding to the third air duct 023 and the air inlet cavity 024, and the first air outlet 041, the second air outlet 042 and the fourth air outlet 044 and the air inlet cavity 024 remain in a normally open state.

[0074] Reference Figure 1 and Figure 4The wind shield 4 also has an air port 45, which forms the entrance of the air inlet cavity 024. Therefore, driven by the wind wheel 300 disposed in the air inlet cavity 024, the airflow flows from the air port 45 to the air outlet in the ventilation assembly, and the wind wheel 300 and the switching device 3 jointly control the flow rate, flow rate and distribution of the airflow in the laundry processing cavity 061.

[0075] Combination Figure 9-12 In the illustrated embodiment, the switching device 3 includes a rotatable wind shield 31, which is used to open and close the inlet of the third air duct 023. When the wind shield 31 is located at a position completely shielding the inlet of the third air duct 023, the switching device 3 closes the inlet of the third air duct 023. When the wind shield 31 is located in a position parallel to the airflow direction, the switching device 3 opens the inlet of the third air duct 023. In some embodiments, the wind shield 31 can be controlled to be located between a position parallel to the airflow direction and a position completely shielding the inlet of the third air duct 023, so as to control the flow rate of the airflow entering the third air duct 023 by controlling the size of the inlet of the third air duct 023.

[0076] like Fig.11 and Fig.12 As shown, the bottom wall of the air duct housing 10 is provided with a fixed shaft 321 perpendicular thereto, and the wind shield 31 is provided on the fixed shaft 321 and is configured to rotate around the fixed shaft 321 under the driving of the airflow.

[0077] During the half-circle rotation of the wind shield 31 around the fixed shaft 321 driven by the airflow, the wind shield 31 is adapted to rotate from a position completely shielding the inlet of the third air duct 023 to a position parallel to the airflow direction, during which the airflow flowing through the third air duct 023 gradually increases, and further, the wind shield 31 rotates from a position parallel to the airflow direction back to a position completely shielding the inlet of the third air duct 023, during which the airflow flowing through the third air duct 023 gradually decreases. When the wind shield 31 is located at a position completely shielding the inlet of the third air duct 023, the switching device 3 closes the inlet of the third air duct 023, and when the wind shield 31 is located at a position parallel to the airflow direction, the switching device 3 opens the inlet of the third air duct 023.

[0078] During the process of the wind shield 31 rotating around the fixed axis 321 for one circle driven by the airflow, the wind shield 31 is suitable for rotating from a position completely covering the inlet of the third air duct 023 to a position parallel to the airflow direction. During the process, the wind shield 31 is inclined toward the first air duct 021 in the airflow direction, and the inclination angle with the airflow direction gradually decreases. At this time, the wind shield 31 will guide the airflow toward the first air duct 021 and gradually open the inlet of the third air duct 023. During this process, the air volume is concentrated in the first air outlet area 41 and the third air outlet area 43.

[0079] Further, the wind shield 31 rotates from a position parallel to the airflow direction back to a position completely covering the inlet of the third air duct 023. During this process, the wind shield 31 is inclined toward the second air duct 022 in the airflow direction, and the inclination angle with the airflow direction gradually increases. At this time, the wind shield 31 will guide the airflow toward the second air duct 022 and gradually close the inlet of the third air duct 023. During this process, the air volume is concentrated in the second air outlet area 42 and the third air outlet area 43.

[0080] To sum up, the rotation of the wind shield 31 can adjust the air volume changes in the first air outlet area 41, the second air outlet area 42 and the third air outlet area 43, thereby changing the air volume changes in different areas in the clothing processing chamber 061, meeting different drying needs and improving the uniformity of clothing drying.

[0081] Reference Fig.11 and Fig.12 The wind shield 31 includes a plurality of wind shields 311, which are arranged at intervals in the circumferential direction of the fixed shaft 321 so that the wind shield 31 can rotate driven by the airflow, and during the rotation of the wind shield 31, the plurality of wind shields 311 can separately or simultaneously close the inlet of the third air duct 023 or guide the airflow flowing toward the air duct.

[0082] In some embodiments, at least two wind shields 311 among the multiple wind shields 311 are relatively arranged on both sides of the fixed shaft 321 so that the wind shield member 31 can rotate at the entrance of the third air duct 023, and when the edges of the two relatively arranged wind shields 311 respectively stop at the two side walls of the entrance of the third air duct 023, the two relatively arranged wind shields 311 can close the entrance of the third air duct 023.

[0083] like Fig.11 and Fig.12 As shown, the projection shape of at least two wind shields 311 on the plane where the inlet of the third air duct 023 is located is the same as the inlet shape of the third air duct 023 to ensure that the two wind shields 311 can completely block the third air duct 023 .

[0084] Reference Fig.11 and Fig.12 The wind shield 311 forms a spiral blade, and the spiral blade can rotate under the drive of the airflow. During the rotation process, the wind shields 311 at different positions can guide the airflow to different air outlet areas, and continuously adjust the air volume changes in the first air outlet area 41, the second air outlet area 42 and the third air outlet area 43, thereby changing the air volume changes in different areas in the clothing processing chamber 061, meeting different drying needs, and improving the uniformity of clothing drying.

[0085] Reference Fig.11 and Fig.12The fixed shaft 321 is arranged in the middle of the inlet of the third air duct 023 so that the wind shield 311 can stably rotate and open and close the inlet of the third air duct 023, ensuring that any wind shield 311 can smoothly pass between the fixed shaft 321 and the side wall of the third air duct 023.

[0086] [Scheme 2]

[0087] like Fig. 9 and Fig.10 As shown, the air duct housing 10 is provided with a rotating shaft 32 parallel to its bottom wall, and the wind shield 31 is provided on the rotating shaft 32 and rotates with the rotating shaft 32. Under the control of the rotating shaft 32, the wind shield 31 can rotate to a position that completely shields the inlet of the third air duct 023. At this time, the switching device 3 closes the inlet of the third air duct 023, the airflow does not pass through the third air duct 023, and the third air outlet 043 does not deliver airflow to the clothes processing chamber 061. Under the control of the rotating shaft 32, the wind shield 31 can rotate to a position parallel to the flow direction of the airflow. At this time, the switching device 3 opens the inlet of the third air duct 023, part of the airflow passes through the third air duct 023, and the third air outlet 043 delivers airflow to the clothes processing chamber 061.

[0088] Furthermore, under the control of the rotating shaft 32, the wind shield 31 can rotate to a position between a position parallel to the airflow direction and a position completely shielding the entrance of the third air duct 023, partially opening the entrance of the third air duct 023, and controlling the flow rate of the airflow entering the third air duct 023 by controlling the size of the entrance of the third air duct 023.

[0089] Reference Fig. 9 and Fig.10 The switching device 3 also includes a driving motor 33, which is connected to the rotating shaft 32 and is used to drive the rotating shaft 32 to rotate. The clothing processing device 1000 can control the rotation of the rotating shaft 32 by controlling the operation of the driving motor 33, and control the rotating shaft 32 to remain stationary at a preset position, thereby controlling the position of the wind shield 31 and controlling the flow of air in the ventilation assembly.

[0090] Combination Figure 9-12 As shown, the inlet of the first air duct 021 and the inlet of the second air duct 022 are in a normally open state, so that no matter whether the inlet of the third air duct 023 is opened or closed, air flows through the first air duct 021 and the second air duct 022 .

[0091] Thus, when the inlet of the third air duct 023 is closed, a part of the airflow in the air inlet chamber 024 is suitable for entering the first air duct 021 through the inlet of the first air duct 021 maintained in the normally open state, and is input into the clothing processing chamber 061 through the first air outlet 041, another part of the airflow is suitable for entering the second air duct 022 through the inlet of the second air duct 022 maintained in the normally open state, and is input into the clothing processing chamber 061 through the second air outlet 042, and another part of the airflow is suitable for input into the clothing processing chamber 061 through the fourth air outlet 044 corresponding to the air inlet chamber 024.

[0092] Further, when the inlet of the third air duct 023 is opened, a part of the airflow in the air inlet chamber 024 is suitable for entering the first air duct 021 through the inlet of the first air duct 021 maintained in the normally open state, and is input into the clothing processing chamber 061 through the first air outlet 041, another part of the airflow is suitable for entering the second air duct 022 through the inlet of the second air duct 022 maintained in the normally open state, and is input into the clothing processing chamber 061 through the second air outlet 042, another part of the airflow is suitable for input into the clothing processing chamber 061 through the fourth air outlet 044 corresponding to the air inlet chamber 024, and another part of the airflow is suitable for entering the third air duct 023 through the inlet of the opened third air duct 023, and is input into the clothing processing chamber 061 through the third air outlet 043.

[0093] According to another embodiment of the present invention, the laundry processing apparatus 1000 comprises the ventilation assembly described in the above embodiment. According to the laundry processing apparatus 1000 of the present invention, by adopting the ventilation assembly, the laundry processing effect of the laundry processing apparatus 1000 is better.

[0094] Combination Figure 1-Figure 8 In the illustrated embodiment, the clothing processing device 1000 also includes: a clothing processing barrel 6, the clothing processing barrel 6 has a clothing processing chamber 061, a first air inlet 0621 and a second air inlet 0631 connected to the clothing processing chamber 061, and in some embodiments, the air inlet position and the air inlet direction of the first air inlet 0621 and the second air inlet 0631 are different, so as to control the distribution of the airflow in the clothing processing chamber 061 by controlling the air volume and wind speed of the first air inlet 0621 and the second air inlet 0631.

[0095] Further, a first air passage cavity 051 and a second air passage cavity 052 are defined between the wind shield 4 and the bottom wall of the laundry processing barrel 6, and the first air passage cavity 051 surrounds the outer side of the second air passage cavity 052. In some embodiments, an annular sealing structure 5 is provided between the wind shield 4 and the bottom wall of the laundry processing barrel 6, and the annular sealing structure includes an outer sealing ring 51 and an inner sealing ring 52, and the first air passage cavity 051 is defined between the outer sealing ring 51 and the inner sealing ring 52, and the second air passage cavity 052 is defined between the inner sealing ring 52, wherein the first air inlet portion 0621 is connected with the first air outlet 041 and the second air outlet 042 through the first air passage cavity 051, and the fourth air outlet 044 is also connected with the first air inlet 0621 through the first air passage cavity 051, thereby, the first air duct 021, the second air duct 022 and the air inlet cavity 024 are connected with the first air passage cavity 051, and since the inlet of the first air duct 021 and the inlet of the second air duct 022 are always open, no matter how the switching device 3 controls the opening and closing of the inlet of the third air duct 023, there is always airflow passing through the first air passage cavity 051. The first air inlet 0621 always inputs airflow into the clothes processing cavity 061.

[0096] The second air inlet 0631 is connected to the third air outlet 043 through the second air passage chamber 052, thereby the switching device 3 controls the air flow interruption between the third air duct 023 and the air inlet chamber 024, and further controls the air flow interruption between the second air passage chamber 052 and the second air inlet 0631 and the air inlet chamber 024. When the switching device 3 closes the entrance of the third air duct 023, the second air inlet 0631 is not connected to the air inlet chamber 024, the second air inlet 0631 does not pass the air flow, and the clothing processing device 1000 only transports the air flow into the clothing processing chamber 061 through the first air inlet 0621. When the switching device 3 opens the entrance of the third air duct 023, the second air inlet 0631 is connected to the air inlet chamber 024, and the clothing processing device 1000 transports the air flow into the clothing processing chamber 061 through the first air inlet 0621 and the second air inlet 0631 at the same time.

[0097] Reference Figure 5 , Figure 6 and Figure 8 An air guide 7 is provided in the clothing processing barrel 6. The air guide 7 is used to connect the clothing processing chamber 061 and the first air inlet 0621 or the second air inlet 0631. A part of the airflow can be guided by the air guide 7 to enter the clothing processing chamber 061 from other directions, so that the airflow in the clothing processing chamber 061 is evenly distributed, avoiding the occurrence of drying dead corners in the clothing processing chamber 061, ensuring the uniformity of the clothing processing process, reducing the clothing processing time, and improving the user experience.

[0098] The following is combined with Figure 1-Figure 10 A specific embodiment of the laundry treating apparatus 1000 is described.

[0099] The clothes treating device 1000 according to the embodiment of the present invention comprises: a ventilation assembly, a wind wheel 300 and a clothes treating assembly 200 .

[0100] The clothing processing assembly 200 includes a clothing processing barrel 6 and two air guides 7, wherein the clothing processing barrel 6 defines a clothing processing cavity 061, the air guides 7 and the barrel wall of the clothing processing barrel 6 define a ventilation cavity 071, and the bottom wall of the clothing processing barrel 6 has a first air inlet area 062 and a second air inlet area 063, and the first air inlet area 062 surrounds the outer side of the second air inlet area 063.

[0102] The second air inlet area 063 is provided with two second air inlet portions 0631, and the two air guides 7 and the two second air inlet portions 0631 correspond in position. The portion of the first air inlet area 062 that is opposite to the air guide 74 is a hole-free structure to prevent the airflow that enters the clothing processing cavity 061 through the second air inlet portion 0631 from entering the ventilation cavity 071, thereby making the airflow in the clothing processing cavity 061 more controllable.

The first air inlet area 062 is provided with two first air inlet portions 0621, and the two air guides 7 correspond to the positions of the two first air inlet portions 0621.

[0104] The air guide member 7 includes: a main body 73 and an air pass member 74, the main body 73 is arranged on the side wall of the clothing processing barrel 6 and defines a first ventilation section 0711 between the main body 73 and the side wall of the clothing processing barrel 6, the air pass member 74 is connected to the main body 73 and is arranged on the bottom wall of the clothing processing barrel 6, and a second ventilation section 0712 connected to the second air inlet portion 0631 is defined between the air pass member 74 and the bottom wall of the clothing processing barrel 6, a plurality of ventilation holes 72 are arranged on the main body 73, the first ventilation section 0711 and the second ventilation section 0712 together constitute a ventilation cavity 071, and the ventilation cavity 071 is connected to the second air inlet portion 0631.

[0105] The main body 73 is formed in a long strip shape and extends axially along the clothing processing barrel 6. One end of the main body 73 is connected to the air pass piece 74 in a circular arc transition so that the air flow in the second ventilation section 0712 defined between the air pass piece 74 and the bottom wall of the clothing processing barrel 6 can enter the first ventilation section 0711 defined by the main body 73 and the side wall of the clothing processing barrel 6.

[0106] The ventilation assembly includes an air duct shell assembly 100 and a wind shield 4. An annular sealing structure is provided between the wind shield 4 and the bottom wall of the clothing processing barrel 6. The annular sealing structure 5 includes an outer sealing ring 51 and an inner sealing ring 52. A first air passage cavity 051 is defined between the outer sealing ring 51, the inner sealing ring 52, the wind shield 4 and the bottom wall of the clothing processing barrel 6. A second air passage cavity 052 is defined between the inner sealing ring 52, the wind shield 4 and the bottom wall of the clothing processing barrel 6.

[0107] The air duct shell assembly 100 is arranged on the side of the wind shield 4 facing away from the clothing processing barrel 6 and defines an air inlet chamber 024, a first air duct 021, a second air duct 022 and a third air duct 023 between the wind shield 4. The air inlet chamber 024 is connected to the inlet of the first air duct 021, the inlet of the second air duct 022, the inlet of the third air duct 023 and the outlet of the clothing processing chamber 061, and a wind wheel 300 is provided in the air inlet chamber 024.

[0108] The wind shield 4 has a first air outlet area 41, a second air outlet area 42, a third air outlet area 43, and a fourth air outlet area 44. The first air duct 021 corresponds to the first air outlet area 41, the second air outlet area 42 corresponds to the second air duct 022, the third air outlet area 43 corresponds to the third air duct 023, and the fourth air outlet area 44 corresponds to the air inlet cavity 024. The first air outlet area 41 is provided with a first air outlet portion 041, the second air outlet area 42 is provided with a second air outlet portion 042, the third air outlet area 43 is provided with a third air outlet portion 043, and the fourth air outlet area 44 is provided with a fourth air outlet portion 044. The first air outlet portion 041, the second air outlet portion 042, and the fourth air outlet portion 044 are provided with a first air outlet hole 411, and the third air outlet portion 043 is provided with a second air outlet hole 421.

[0109] The total opening area of ​​all the first air outlet holes 411 is smaller than the total opening area of ​​all the second air outlet holes 421, so as to avoid the opening of the first air outlet holes 411 affecting the strength of the periphery of the wind shield 4, thereby ensuring the strength and reliability of the wind shield 4. In addition, by making the total opening area of ​​the first air outlet holes 411 smaller than the total opening area of ​​all the second air outlet holes 421, the flow area of ​​the first air outlet portion 041 is smaller than the flow area of ​​the second air outlet portion 042, which is conducive to increasing the air volume of the second air inlet portion 0631 and the air flow velocity of the first air inlet portion 0621, thereby better controlling the distribution of the air flow in the clothing processing chamber 061 and the blowing direction.

[0110] Reference Figure 1 and Figure 4 The opening area of ​​a single first air outlet hole 411 is smaller than the opening area of ​​a single second air outlet hole 421 to avoid the opening of the first air outlet hole 411 affecting the strength of the periphery of the wind shield 4, thereby ensuring the strength and reliability of the wind shield 4.

[0111] The first air outlet hole 411 and the second air outlet hole 421 include a plurality of first air outlet holes 411 arranged at intervals along the circumference and / or radial direction of the second air outlet area 42, and the plurality of second air outlet holes 421 arranged at intervals along the circumference and / or radial direction of a circle, so that the first air outlet holes 411 and the second air outlet holes 421 can be evenly distributed, ensuring the uniform air volume in the clothing processing chamber 061 and ensuring the uniformity of clothing processing by the clothing processing device 1000. The first air outlet holes 411 and the second air outlet holes 421 are formed into long holes extending along the circumference of the circle for easy opening, so as to avoid the opening of the first air outlet holes 411 and the second air outlet holes 421 affecting the strength of the wind shield 4, and the first air outlet holes 411 and the second air outlet holes 421 can be opened larger while ensuring the strength of the wind shield 4.

[0112] The first air outlet portion 041 connects the first air duct 021 and the first air passage cavity 051, the second air outlet portion 042 connects the second air duct 022 and the first air passage cavity 051, the fourth air outlet portion 044 connects the air inlet cavity 024 and the first air passage cavity 051, and the third air outlet portion 043 connects the third air duct 023 and the second air passage cavity 052. Thus, the airflow in the first air duct 021, the second air duct 022 and part of the air inlet cavity 024 enters the clothing processing cavity 061 from the first air inlet portion 0621 through the first air passage cavity 051, and the airflow in the third air duct 023 enters the clothing processing cavity 061 from the second air inlet portion 0631 through the second air passage cavity 052. In some embodiments, the first air inlet portion 0621 is communicated with the ventilation cavity 071 of the air guide member 7, and in other embodiments, the second air inlet portion 0631 is communicated with the ventilation cavity 071 of the air guide member 7, and the ventilation cavity 071 is then communicated with the clothing processing cavity 061 through the ventilation holes 72 opened on the air guide member 7.

[0113] Specifically, after passing through the clothing processing chamber 061, the dry airflow carries moisture in the clothing, and the airflow is discharged from the clothing processing chamber 061 through the outlet of the clothing processing chamber 061. After the drying treatment, the airflow enters the air inlet chamber 024 defined by the air duct shell assembly 100 under the drive of the wind wheel 300. The dry airflow in the air inlet chamber 024 is split at the inlets of the first air duct 021, the second air duct 022 and the third air duct 023, one part of which passes through the first air duct 021, the first air outlet 041, the first air passage chamber 051 and the first air inlet 0621 in sequence to enter the clothing processing chamber 061, another part passes through the second air duct 022, the second air outlet 042, the first air passage chamber 051 and the first air inlet 0621 in sequence to enter the clothing processing chamber 061, and another part passes through the fourth air outlet 044, the first air passage chamber 051 and the first air inlet 0621 to enter the clothing processing chamber 061. This part of the airflow flows from the bottom wall of the clothing processing chamber 061 into the clothing processing chamber 061, and the other part passes through the third air duct 023, the third air outlet portion 043, the second air passage chamber 052, the second air inlet portion 0631, the second ventilation section 0712 and the first ventilation section 0711 in sequence, and then enters the clothing processing chamber 061 through the ventilation holes 72 opened on the main body 73 of the air guide member 7. This part of the airflow flows from the side wall of the clothing processing chamber 061 into the clothing processing chamber 061.

[0114] Since the clothing processing chamber 061 has airflow flowing from the side wall of the clothing processing barrel 6 into the clothing processing chamber 061 in addition to the airflow flowing from the bottom wall of the clothing processing barrel 6, the clothing processing device 1000 has a more uniform drying effect on the clothes, thereby improving the clothing processing effect of the clothing processing device 1000, reducing the clothing processing time, and improving the user experience.

[0115] In some embodiments, the air guide 7 can be formed as lifting ribs in the clothing treatment barrel 6, which can play a certain stirring role on the clothes while achieving air guidance, thereby ensuring uniformity of clothing treatment.

[0116] The air duct shell assembly 100 includes an air duct shell 10 and a switching device 3. The air duct shell 10 includes a first cover shell 2, a second cover shell 1 and two partitions 21. The partition 21 is arranged in the first cover shell 2 and is connected to the bottom wall and the side wall of the first cover shell 2. The two partitions 21 are arranged at intervals. A second air duct 022 is defined between the two partitions 21. A first air duct 021 is defined between the partition 21 and the side wall of the first cover shell 2. Since an air duct is defined between each of the two partitions 21 and one side wall of the air duct shell 10, the first air duct 021 includes two air outlet cavities 0211.

[0117] The partition 21 includes: a first partition plate 211, a second partition plate 212 and a plurality of reinforcing ribs 213, each of the first partition plate 211 and the second partition plate 212 is connected to the bottom wall of the first cover shell 2, and the plurality of reinforcing ribs 213 are arranged between the first partition plate 211 and the second partition plate 212, and are arranged at intervals in the length direction of the partition 21, so as to utilize the reinforcing ribs 213 to enhance the strength of the first partition plate 211 and the second partition plate 212 to avoid cracking and deformation of the first partition plate 211 or the second partition plate 212, and a cavity is formed between the first partition plate 211 and the second partition plate 212, and the cavity is divided by the reinforcing ribs 213 to form a plurality of reinforced cavities 217, and the partition 21 utilizes the reinforced cavity 217 to improve the structural strength of the partition 21 to ensure the reliability and stability of the partition 21, and the reinforced cavity 217 can reduce the weight of the partition 21 to avoid the setting of the partition 21 affecting the lightweight of the clothing processing device 1000.

[0118] The partition 21 includes: a first partition section 214 and a second partition section 215. The first partition section 214 is parallel to and spaced from the side wall of the first housing 2 near the inlet of the first air duct 021, so as to avoid the partition 21 affecting the wind resistance of the first air duct 021 and the second air duct 022 and avoid loss during the flow of air. The second partition section 215 is connected between one end of the first partition section 214 and the side wall of the first housing 2.

[0119] The second housing 1 is sleeved on the outside of the first housing 2 to protect the first housing 2 and the internal structure of the clothing processing device 1000, and to isolate noise, reduce vibration, etc.

[0120] The switching device 3 is used to open and close the inlet of the second air duct 022 to control the interruption of the air flow between the second air duct 022 and the air inlet chamber 024. The clothing processing device 1000 can control the air flow rate or flow rate in the first air duct 021 and the second air duct 022 by controlling the switching device 3, and then the flow rate of the air flow flowing into the clothing processing chamber 061 through the first air inlet hole or ventilation hole 72, so as to better control the distribution of the air flow in the clothing processing chamber 061 and the direction of the air flow, so that the clothing processing device 1000 can have a variety of different ventilation modes and can switch between a variety of different ventilation modes, so that the clothing processing process is more uniform.

[0121] In some embodiments, the switching device 3 includes a wind shield 31, a rotating shaft 32 and a driving motor 33. The rotating shaft 32 is parallel to the bottom wall of the air duct shell 10. The wind shield 31 is arranged on the rotating shaft 32 and rotates with the rotating shaft 32. The driving motor 33 is connected to the rotating shaft 32 and is used to drive the rotating shaft 32 to rotate. The clothing processing device 1000 can control the rotation of the rotating shaft 32 by controlling the operation of the driving motor 33, and control the rotating shaft 32 to remain stationary at a preset position, thereby controlling the position of the wind shield 31 and controlling the flow of air in the ventilation component.

[0122] The wind shield 31 can be driven by the driving motor 33 to rotate to a position that completely shields the inlet of the third air duct 023. At this time, the switching device 3 closes the inlet of the third air duct 023, the airflow does not pass through the third air duct 023, and the third air outlet 043 does not deliver airflow to the clothes processing chamber 061. Further, the wind shield 31 can be rotated to a position parallel to the flow direction of the airflow. At this time, the switching device 3 opens the inlet of the third air duct 023, part of the airflow passes through the third air duct 023, and the third air outlet 043 delivers airflow to the clothes processing chamber 061.

[0123] Under the control of the drive motor 33, the wind shield 31 can also rotate to a position between a position parallel to the airflow direction and a position completely covering the entrance of the third air duct 023, partially opening the entrance of the third air duct 023, and controlling the flow rate of the airflow entering the third air duct 023 by controlling the size of the entrance of the third air duct 023.

[0124] In other embodiments, the switching device 3 includes a wind shield 31 and a fixed shaft 321, the fixed shaft 321 is arranged in the middle of the inlet of the third air duct 023, the wind shield 31 includes two wind shields 311, the two wind shields 311 are arranged opposite to each other on both sides of the fixed shaft 321, and the projection shape of the two wind shields 311 on the plane where the inlet of the third air duct 023 is located is the same as the inlet shape of the third air duct 023, the wind shield 311 forms a spiral blade, and the spiral blade can rotate around the fixed shaft 321 driven by the airflow. During the rotation process, the wind shields 311 at different positions can guide the airflow to different air outlet areas, and continuously adjust the air volume changes of the first air outlet area 41, the second air outlet area 42 and the third air outlet area 43, thereby changing the air volume changes in different areas in the clothing processing chamber 061, meeting different drying needs, and improving the uniformity of clothing drying.

[0125] Specifically, during the half-circle rotation of the wind shield 31 around the fixed shaft 321 driven by the airflow, the wind shield 31 is adapted to rotate from a position completely shielding the inlet of the third air duct 023 to a position parallel to the airflow direction, during which the airflow flowing through the third air duct 023 gradually increases, and further, the wind shield 31 rotates from a position parallel to the airflow direction back to a position completely shielding the inlet of the third air duct 023, during which the airflow flowing through the third air duct 023 gradually decreases. When the wind shield 31 is located at a position completely shielding the inlet of the third air duct 023, the switching device 3 closes the inlet of the third air duct 023, and when the wind shield 31 is located at a position parallel to the airflow direction, the switching device 3 opens the inlet of the third air duct 023.

[0126] During the process of the wind shield 31 rotating around the fixed axis 321 for one circle driven by the airflow, the wind shield 31 is suitable for rotating from a position completely covering the inlet of the third air duct 023 to a position parallel to the airflow direction. During the process, the wind shield 31 is inclined toward the first air duct 021 in the airflow direction, and the inclination angle with the airflow direction gradually decreases. At this time, the wind shield 31 will guide the airflow toward the first air duct 021 and gradually open the inlet of the third air duct 023. During this process, the air volume is concentrated in the first air outlet area 41 and the third air outlet area 43.

[0127] Further, the wind shield 31 rotates from a position parallel to the airflow direction back to a position completely covering the inlet of the third air duct 023. During this process, the wind shield 31 is inclined toward the second air duct 022 in the airflow direction, and the inclination angle with the airflow direction gradually increases. At this time, the wind shield 31 will guide the airflow toward the second air duct 022 and gradually close the inlet of the third air duct 023. During this process, the air volume is concentrated in the second air outlet area 42 and the third air outlet area 43.

[0128] To sum up, the rotation of the wind shield 31 can adjust the air volume changes in the first air outlet area 41, the second air outlet area 42 and the third air outlet area 43, thereby changing the air volume changes in different areas in the clothing processing chamber 061, meeting different drying needs and improving the uniformity of clothing drying.
