[0051] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0052] like Figures 1 to 9 The air valve assembly shown in the figure comprises: a fixed tube body 1, a first end of the fixed tube body 1 is provided with a first air inlet 11, a second end of the fixed tube body 1 is provided with an air outlet 12, and a side wall of the fixed tube body 1 is provided with a second air inlet 13, so that the fixed tube body 1 can take in air from two directions corresponding to the first end and the side wall, thereby overcoming the problem of increased structural size caused by the parallel arrangement of the fresh air channel and the return air channel in the prior art; a rotating member 2, which is rotatably arranged in the fixed tube body 1, and the rotating member 2 has the function of making the first air inlet 11 In the first state in which the second air inlet 13 is connected to the air outlet 12 and the second air inlet 13 is closed, and in the second state in which the second air inlet 13 is connected to the air outlet 12 and the first air inlet 11 is closed, the rotating member 2 is arranged inside the fixed tube body 1, so that the structural size of the air valve assembly can be limited to the size of the fixed tube body 1, thereby overcoming the problem in the prior art that the plate-shaped swinging member switches the fresh air channel and the return air channel, which requires a larger installation size and avoidance size, and effectively reduces the size of the air valve assembly or even the structure using the air valve assembly.

[0053] The fixed tube body 1 is a cylindrical structure, the rotating member 2 is arranged inside the fixed tube body 1, and the rotating member 2 can rotate around the axis of the fixed tube body 1, so that the movable range of the rotating member 2 is limited to the inside of the fixed tube body 1, effectively reducing the structural size of the air valve assembly.

[0054] The rotating member 2 is arranged inside the fixed tube body 1, and the rotating member 2 includes a first seal 21 and a second seal 22 which are connected to each other; when the rotating member 2 is in the first state, the first seal 21 opens the first air inlet 11 and the second seal 22 is sealed at the second air inlet 13; when the rotating member 2 is in the second state, the second seal 22 opens the second air inlet 13 and the first seal 21 is sealed at the first air inlet 11, so that the first seal 21 is used to control the working state of the first air inlet 11, and the second seal 22 is used to control the working state of the second air inlet 13, and the first seal 21 and the second seal 22 can rotate simultaneously, so that the working state of the first air inlet 11 and the working state of the second air inlet 13 can be switched in a linked manner.

[0055] Preferably, the rotating member 2 is L-shaped, and the bottom section of the L-shape (the first seal 21) is located at the end face of the first end, and the vertical section of the L-shape (the second seal 22) is located on the side wall of the fixed tube body 1, and the projection of the first air inlet 11 at the end face of the first end and the projection of the second air inlet 13 at the end face of the first end do not overlap and there is even a gap between them, so that when the L-shape is sealed with the first air inlet 11, the part of the L-shape that cooperates with the second air inlet 13 is not at the second air inlet 13, so that the second air inlet 13 is in an open state. Similarly, when the L-shape is sealed with the second air inlet 13, the part of the L-shape that cooperates with the first air inlet 11 is not at the first air inlet 11, and the first air inlet 11 is in an open state.

[0056] The first sealing member 21 is parallel to the end face of the first end, the second sealing member 22 matches the side wall of the fixed tube body 1, a positioning shaft is provided on the first sealing member 21, and a positioning hole is provided on the second sealing member 22, and the axis of the positioning shaft and the axis of the positioning hole are both collinear with the axis of the fixed tube body 1.

[0057] The first air inlet 11 includes a plurality of fan-shaped air outlets 3, all of which are evenly distributed on the end surface of the first end, and the first seal 21 corresponds to the fan-shaped air outlets 3 one by one, that is, the first air inlet 11 is divided into a plurality of fan-shaped air outlets 3, so that the end of the fixed tube body 1 can evenly intake air, and the number of the first seals 21 is multiple, so that during the rotation process, the first seal 21 can adjust the opening and closing state of the corresponding fan-shaped air outlet 3, effectively reduce the rotation angle of the first seal 21, and increase the switching speed of the opening and closing state of the first air inlet 11.

[0058] A first avoidance area 4 is set between two adjacent fan-shaped air outlets 3, and when the rotating member 2 is in the first state, the first seal 21 is located in the corresponding first avoidance area 4, thereby preventing the first seal 21 from shielding the first air inlet 11 and affecting the air intake of the first air inlet 11.

[0059] The radius of the fan-shaped air outlet 3 is equal to the radius of the end face of the first end, or the center of the vertices of all the fan-shaped air outlets 3 is coincident with the center of the end face of the first end, that is, the end face of the first end is divided according to a certain central angle to form a plurality of fan-shaped air outlets 3.

[0060] The first avoidance area 4 is fan-shaped, and the center of the fan is coincident with the center of the end face of the first end, that is, the end face of the first end is divided according to a certain central angle, and the structure corresponding to two adjacent central angles is a avoidance area and a fan-shaped air outlet 3.

[0061] The fan-shaped shape, the fan-shaped air outlet 3 and the first seal 21 are all the same, and when the rotating member 2 is in the second state, the first seal 21 overlaps with the first avoidance area 4, so that when the first seal 21 rotates to the first avoidance area 4, the first seal 21 will not block the fan-shaped air outlet 3 while maximizing the flow area of ​​the first air inlet 11.

[0062] The second air inlet 13 includes a plurality of strip air outlets 5, all of which are evenly distributed on the side wall of the fixed tube body 1, and the second seal 22 corresponds to the strip air outlet 5 one by one, so that the side wall of the fixed tube body 1 can take in air in multiple directions, thereby ensuring the air intake efficiency of the side wall of the fixed tube body 1. At the same time, the number of the second seals 22 is multiple, and the second seals 22 can adjust the opening and closing states of the corresponding strip air outlets 5, effectively reducing the rotation angle of the second seal 22 and increasing the switching speed of the opening and closing states of the second air inlet 13.

[0063] A second avoidance area 6 is provided between two adjacent strip air vents 5, and when the rotating member 2 is in the second state, the second seal 22 is located in the corresponding second avoidance area 6, so as to prevent the second seal 22 from shielding the strip air vents 5 and affecting the air intake efficiency of the second air inlet 13.

[0064] The length direction of the strip air outlet 5 is parallel to the axis of the fixed tube body 1, that is, along the length direction of the fixed tube body 1, a long strip air outlet 5 is opened on the side wall of the fixed tube body 1, thereby maximizing the air intake of the side wall of the fixed tube body 1.

[0065] The length of the strip air port 5 is equal to the length of the fixed tube body 1 , which further increases the flow area of ​​the second air inlet 13 .

[0066] Because the fixed tube body 1 is a cylindrical structure, the strip air outlet 5 is opened on the side wall of the cylindrical structure, so the cross-section of the strip air outlet 5 is arc-shaped, and the center of the arc is on the axis of the fixed tube body 1, so that the flow area of ​​each strip air outlet 5 reaches the optimal value, ensuring that the flow area of ​​the second air inlet 13 is at the maximum.

[0067] The shape of the second avoidance area 6, the shape of the strip air outlet 5 and the shape of the second seal 22 are all the same, and when the rotating member 2 is in the first state, the second seal 22 overlaps with the second avoidance area 6, thereby preventing the second seal 22 from shielding the corresponding strip air outlet 5 while maximizing the flow area of ​​the second air inlet 13.

[0068] The first seal 21 is fan-shaped, and the cross-section of the second seal 22 is arc-shaped. The vertex of the fan-shape and the center of the circle corresponding to the cross-section of the second seal 22 are on the axis of the fixed tube body 1, and the central angle angle corresponding to the cross-section of the first seal 21 is equal to the central angle angle corresponding to the second seal 22. Therefore, when the rotating member 2 switches between the first state and the second state, it is only necessary to rotate the central angle angle corresponding to the cross-section of the first seal 21 to achieve the state switching of the first air inlet 11 and the second air inlet 13.

[0069] The air valve assembly also includes:

[0070] The driving mechanism 7 is arranged on the fixed tube body 1, and the driving mechanism 7 drives the rotating member 2 to switch between the first state and the second state, that is, the driving mechanism 7 drives the rotating member 2 to rotate around the axis of the fixed tube body 1.

[0071] The driving mechanism 7 includes a driving tooth 71 and a rack 72, wherein the driving tooth 71 is fixedly disposed on the fixed tube body 1, and the rack 72 is disposed on the rotating member 2, and the driving tooth 71 and the rack 72 are meshed for transmission. In particular, the driving tooth 71 is driven by a motor. When the motor rotates forward, the driving tooth 71 cooperates with the rack 72 to drive the rotating member 2 to rotate in a first direction, and when the motor rotates reversely, the driving tooth 71 cooperates with the rack 72 to drive the rotating member 2 to rotate in a second direction.

[0072] The first seal 21 is fan-shaped, the cross-section of the second seal 22 is arc-shaped, the shape of the rack 72 is arc-shaped, and the vertex of the fan-shape, the center of the circle corresponding to the cross-section of the second seal 22 and the center of the circle corresponding to the arc of the rack 72 are all on the axis of the fixed tube body 1, the central angle angle corresponding to the first seal 21 and the central angle angle corresponding to the cross-section of the second seal 22 are equal, and the central angle angle corresponding to the rack 72 is greater than or equal to the central angle angle of the first seal 21, that is, the length of the rack 72 should be greater than the rotation distance of the rotating member 2, thereby ensuring that the rotating member 2 can rotate reliably.

[0073] The first air inlet 11 is provided with a filtering mechanism 8 for filtering the gas flowing into the first air inlet 11 .

[0074] The first end is provided with a mounting groove, and the filter mechanism 8 is detachably arranged in the mounting groove.

[0075] The air valve assembly also includes an interface part, which is arranged at the first end, and the interface part and the first end together form the installation groove. At the same time, the air valve assembly is connected to the corresponding gas pipeline through the interface part, thereby ensuring that all air flows entering through the interface part must pass through the filtering mechanism 8 and then flow into the first air inlet 11.

[0076] The air valve assembly further includes a purification mechanism, which is disposed inside the fixed tube body 1 to purify the gas entering the fixed tube body 1 to improve the cleanliness of the gas.

[0077] The purification mechanism is disposed on a surface of the rotating member 2 away from the fixed tube body 1 to prevent the purification mechanism from blocking the rotating member 2 and affecting the sizes of the first air inlet 11 and the second air inlet 13 .

[0078] An indoor unit comprises the above-mentioned air valve assembly.

[0079] The indoor unit has a fresh air inlet and a return air inlet, the fresh air inlet is connected to the first air inlet 11, and the return air inlet is connected to the second air inlet 13. In particular, the indoor unit includes a shell, the fresh air inlet and the return air inlet are both arranged on the shell, and the fresh air inlet is connected to the outdoors through a pipeline, while the return air inlet is connected to the indoors.

[0080] Particularly, the air valve assembly is fixedly arranged on the inner surface of the shell, and the first air inlet 11 directly penetrates the shell to form a fresh air inlet, and the interface part is located outside the shell.

[0081] The interface piece is provided with an anti-slip rib which is fixedly matched with the fresh air pipeline.

[0082] An installation groove is provided at the first end, and the filter mechanism 8 is detachably provided in the installation groove, and the filter mechanism 8 enters or escapes from the installation groove through the return air inlet, that is, the filter mechanism 8 can be directly disassembled and assembled from the return air inlet, thereby increasing the convenience of disassembly and assembly of the filter mechanism 8. When the return air inlet is at the lower side of the indoor unit, the filter mechanism 8 slides up and down for disassembly and assembly, and when the return air inlet is at the rear side of the indoor unit, the filter mechanism 8 slides horizontally for disassembly and assembly. In particular, a clamping structure for clamping the filter mechanism 8 is provided in the installation groove.

[0083] The indoor unit includes a fan 9, an air inlet of the fan 9 is connected to the air return port, and a sealing shock-absorbing member is provided between the fan 9 and the air valve assembly to avoid noise generated by contact between the air valve assembly and the fan 9.

[0084] The material of the sealing and shock absorbing component includes sponge.

[0085] The above-mentioned embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the present invention. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.
