Referring to fig. 4 to 7, the damper switching assembly 4 includes a damper 100 and a base 41; two dampers 100 are connected to the base 41 in a side-to-side arrangement.

The damper 100 includes a housing 110 and a damper 120. The outer frame 110 has a substantially rectangular frame shape, and the damper 120 is installed in the outer frame 110.

The damper 120 includes a first swing blade 121 and a second swing blade 122. The opening and closing states of the first swing blade 121 and the second swing blade 122 are opposite, that is, when the first swing blade 121 is in a closed state, the second swing blade 122 is in an open state, and when the first swing blade 121 is in an open state, the second swing blade 122 is in a closed state.

The first swing blade 121 and the second swing blade 122 are disposed in a tandem arrangement. By the states of the first swing blade 121 and the second swing blade 122, the front and rear portions of the damper 120 can be controlled to assume an open-close state.

The following description of the orientation of the damper switching assembly 4 will be made taking the example in which the damper 100 is located at the top end of the base 41.

Referring to fig. 4 and 8, a first air chamber 411 and a second air chamber 412 are provided on the base 41; the opening of the first air cavity 411 at the upper end of the base 41 corresponds to the first swing blades 121 of the two air doors 100, and the opening of the first air cavity 411 at the lower end of the base 41 is positioned at the right side; the opening of the second air chamber 412 at the upper end of the base 41 corresponds to the second swing blades 121 of the two dampers 100, and the opening of the second air chamber 412 at the lower end of the base 42 is located at the left side.

Referring to the left side view of fig. 9, when the first swing vane 121 of the right side damper 100 is opened and the second swing vane 122 is closed, the first air chamber 411 corresponding to the first swing vane 121 is communicated, and the opening of the first air chamber 411 at the lower end is located at the right side, so that air enters from the right side damper 100 of the damper switching assembly 4, flows out from the right side of the lower end, or enters from the right side of the lower end of the damper switching assembly 4, flows out from the right side damper 100, and realizes the right-in and left-out of air.

Referring to the right view of fig. 9, when the second swing vane 122 of the left air valve 100 is opened and the first swing vane 121 is closed, the second air chamber 412 corresponding to the second swing vane 122 is communicated, and the lower end opening of the second air chamber 412 is located at the left side, so that air enters from the left air valve 100 of the air valve switching assembly 4, flows out from the left side of the lower end, or enters from the left side of the lower end of the air valve switching assembly 4, flows out from the left air valve 100, and realizes left in and left out of air.

Referring to the left side view of fig. 10, when the first swing vane 121 of the left side damper 100 is opened and the second swing vane 122 is closed, the first air chamber 411 corresponding to the first swing vane 121 is communicated, and the opening at the lower end of the first air chamber 411 is located at the left side, so that air enters from the left side damper 100 of the damper switching assembly 4, flows out from the right side, and realizes left, right and left inlets and outlets of downward flow. When air enters from the right side of the lower end of the damper switching assembly 4, the air flows out from the left damper 100, and the upward flow of the air enters from the right side and exits from the left side.

Referring to the right view of fig. 10, when the second swing vane 122 of the right air valve 100 is opened and closed, the first swing vane 121 Guan Shi, the second air chamber 412 corresponding to the second swing vane 122 is communicated, and the opening at the lower end of the second air chamber 412 is located on the right side, so that air enters from the right air valve 100 of the air valve switching assembly 4, and flows out from the left side to realize downward flow, left in and right out. When air enters from the left side of the lower end of the damper switching assembly 4, the air flows out from the right damper 100, and the air enters and exits from the right side in an upward flow.

According to an embodiment of the present application, the first damper switching assembly 401 is flip-chip mounted at the lower end of the humidity processing chamber, that is, the damper 100 is located at the lower end of the base 41 in the first damper switching assembly 401.

First state of damper switching assembly 4:

In the left side damper 100 of the first damper switching assembly 401, the first swing blade 121 is opened, and the second swing blade 122 is closed; in the right side damper 100 of the first damper switching assembly 401, the first swing blade 121 is closed and the second swing blade 122 is opened.

In the left side damper 100 of the second damper switching assembly 402, the first swing blade 121 is closed and the second swing blade 122 is opened; in the right damper 100 of the second damper switching assembly 402, the first swing blade 121 is opened and the second swing blade 122 is closed.

Fresh air flows from the left side damper 100 of the first damper switching assembly 401 into the left side first humidity chamber 14a, and then flows from the left side damper 100 of the second damper switching assembly 402 into the left side fresh air exhaust chamber; the exhaust air flows from the right side damper 100 of the first damper switching assembly 401 into the right side second humidity treatment chamber 14b, and then flows from the right side damper 100 of the second damper switching assembly 402 into the right side return air exhaust chamber, so that the first humidity treatment chamber 14a is communicated with the fresh air duct, and the second humidity treatment chamber 14b is communicated with the exhaust air duct.

Second state of damper switching assembly 4:

In the left side damper 100 of the first damper switching assembly 401, the first swing blade 121 is closed, and the second swing blade 122 is opened; in the right side damper 100 of the first damper switching assembly 401, the first swing blade 121 is opened and the second swing blade 122 is closed.

In the left side damper 100 of the second damper switching assembly 402, the first swing blade 121 is opened, and the second swing blade 122 is closed; in the right damper 100 of the second damper switching assembly 402, the first swing blade 121 is closed and the second swing blade 122 is opened.

Fresh air flows from the left side damper 100 of the first damper switching assembly 401 into the right side second humidity chamber 14b, and then flows from the right side damper 100 of the second damper switching assembly 402 into the left side fresh air exhaust chamber; the exhaust air flows from the right side damper 100 of the first damper switching assembly 401 into the left side first humidity treatment chamber 14a, and then flows from the left side damper 100 of the second damper switching assembly 402 into the right side return air exhaust chamber, so that the second humidity treatment chamber 14b is communicated with the fresh air duct, and the first humidity treatment chamber 14a is communicated with the exhaust air duct.

The switching of the air flow is achieved by the switching of the damper switching assembly 4 between the first state and the second state.

In the application, two air doors 100 are arranged on the base 41, so that the integration of the air doors 100 is realized, and the problems of time and labor waste during disassembly and assembly due to the fact that the number of air valves is relatively large and the connecting structure is relatively complex in the prior art are avoided; in addition, when a plurality of air valves are independently arranged in the air duct in the prior art, the connecting gaps of the air valves in the air duct are dispersed, and the design of a sealing structure is difficult.

According to an embodiment of the present application, if the first swing blade 121 and the second swing blade 122 are provided as one, the width of the swing blade may be relatively large, and when the swing blade is in an open state, i.e., the side of the swing blade is vertical, this may cause the damper 120 to have a relatively large vertical dimension, and thus the height dimension of the damper 100 may be relatively large.

Therefore, in order to reduce the height dimension of the damper 100, the number of the first swing blades 121 and the second swing blades 122 is plural, and the plurality of swing blades are distributed in the front-rear direction, and at this time, the width of the swing blades may be designed to be relatively small, so that the vertical dimension of the damper 100 is relatively small.

Referring specifically to fig. 5 to 7, the damper 120 further includes a connecting rod, and the connecting rod drives and connects the swing blades, so that synchronous rotation of a plurality of swing blades can be realized by one power element, so as to reduce the number of power elements.

Since the rotation directions of the first swing blade 121 and the second swing blade 122 are opposite, the first swing blade 121 and the second swing blade 122 need to be in transmission connection by different connecting rods, specifically, the first swing blade 121 is connected with the first connecting rod 123, and the second swing blade 122 is connected with the second connecting rod 124.

According to the embodiment of the application, the top end of the accommodating groove 410 is provided with the limiting rib 415, and the limiting rib 415 abuts against the outer frame 110, so that the vertical movement of the air door 100 can be limited, and the air door 100 is prevented from being separated from the notch of the accommodating groove 410.

In some embodiments of the present application, referring to fig. 19 and 20, a motor mounting groove 113 is formed at an end of the outer frame 110 opposite to the fool-proof rib 111, the motor mounting groove 113 is recessed toward a side near the fool-proof rib 111, a motor 126 is fixedly installed in the motor mounting groove 113, and an output shaft of the motor 126 is connected to the rotation shaft 125.

The motor 126 is not exposed to the outer surface of the outer frame 110 to ensure that the motor 126 does not interfere with the base 41 when the damper 100 is mounted to the base 41.

The motor 126 is mounted on the opposite side of the fool-proof rib 111 such that the motor 126 is adjacent to the wind barrier 416 of the base 41 on the damper switching assembly 4, so that the wires connecting the motor 126 in both dampers 100 are adjacent to the wind barrier 416, resulting in a relatively concentrated wire.

When the damper 100 needs to be maintained, the damper 100 is directly pulled out from the base 41, and the connector on the motor 126 is disconnected.

The groove top of the rotating shaft mounting part 116 is provided with an outward transversely extending abutting part 1161, and when the swing blade is in a closed state, the swing blade close to the abutting part abuts against the abutting part 1161 so as to realize the sealing between the swing blade and the rotating shaft mounting part 116.

Swing blade mounting holes 117 for mounting the swing blades are formed in the left and right side walls of the outer frame 110, and are used for mounting two shaft ends of the swing blades.

In some embodiments, the inner surface of the left side wall of the outer frame 110 is provided with a left concave guiding groove 118, the bottom end of the guiding groove 118 penetrates through the outer frame 110, and the upper end of the guiding groove 118 is communicated with the swing blade mounting hole 117; the rotation shaft of the swing blade can be fitted into the swing blade mounting hole 117 along the guide groove 118.

When the swing blade is made of metal, the swing blade cannot be installed into the swing blade installation hole through slight bending deformation like plastic during assembly, so that the right end of the swing blade can be installed into the swing blade installation hole 117 first, and the left end of the swing blade enters the swing blade installation hole 117 through the guide groove 118.

The arrangement of the guide grooves 118 can reduce the deformation of the plastic outer frame 110 when the swing blades are installed, and meanwhile, the guide function of the guide grooves 118 can save more time and labor during installation.

The inner surface of the right side wall of the outer frame 110 is provided with a positioning protrusion 119, the positioning protrusion 119 is located at the periphery of the swing blade mounting hole 117, the area of the positioning protrusion 119 is smaller than the area taking the width of the swing blade as the diameter, so that the swing blade is contacted with the positioning protrusion 119 during rotation, the area of the positioning protrusion 119 is smaller, and the abrasion of the swing blade can be reduced.

A bearing bracket can be arranged between the rotating shaft 125 and the swing blade mounting hole 117 of the outer frame 110; the bearing support can be molded by adopting fluorine-dragon polytetrafluoroethylene PTFE, and the material has better wear resistance and extremely low friction coefficient, can reduce friction and improve the reliability of mechanism movement.

In some embodiments, in order to avoid friction loss and abnormal noise caused by contact between the swing blade and the outer frame 110, an assembly gap is reserved between the swing blade and the inner side wall of the outer frame 110 in the axial direction, and the gap has a risk of air leakage.

Therefore, the application is provided with the wind shielding boss 1101 on the inner side wall of the outer frame, the shape of the wind shielding boss 1101 corresponds to the running track of the swing blade, and the left end and the right end of the swing She Benti are positioned in the wind shielding boss 1101. The wind shielding boss 1101 can increase wind resistance at the reserved gap and reduce air leakage.

In some embodiments, in order to avoid the problems of failure of an operating mechanism or air leakage and the like caused by thermal deformation of the swing blade, the swing blade is molded by adopting an aluminum alloy casting mode.

When the swing blades are in a closed state, the edges of two adjacent swing blades are overlapped, and the overlapped mode can ensure the tightness of the closed state.

Referring to fig. 21, a rubber layer 1214 is attached to the lap of the swing blades, and the rubber layer 1214 has a certain compressibility, and the rubber layer 1214 between the swing blades can be pressed together by the locking force of the motor 126, thereby improving the sealing performance.

The rubber layer 1214 can adopt ethylene propylene diene monomer rubber, the heat resistance, weather resistance and ageing resistance of the material are excellent, and because the ethylene propylene rubber molecular structure lacks an active gene, the cohesive energy is low, the self-adhesion and the mutual adhesion of the rubber material are very poor, and the problem that the motor torque is increased by adhering the rubber between two swing blades after the machine is not operated for a long time, so that the air valve is invalid is avoided.

The edge of the swing blade is provided with a sealing part 1215 formed by thinning, and the rubber layer 1214 is wrapped outside the sealing part 1215.

Specifically, if the rubber layer 1214 is fixed to the swing blade by means of simple gluing, the problem of air leakage due to degumming may be caused with aging for a long time. Therefore, in the present application, the fixing hole is provided in the sealing portion 1215, and rubber may be injected into the fixing hole for connecting the rubber on both sides of the joint surface during the injection molding of the rubber, thereby integrally fixing the fixing hole to the swing blade.

The present application also provides another embodiment of the damper 100 in which only one motor is used to drive the two dampers 120, reducing the number of motors, reducing costs, and simplifying the control of the damper 100.

Referring to fig. 22 to 26, the damper 100 further includes a central shaft 130, and the central shaft 130 is rotatably connected to the outer frame 110 and located between the first damper 1201 and the second damper 1202.

In this embodiment, the inner shaft 125 of the damper 120 acts as a drive shaft, and is not connected to a motor, but only the central shaft 130 is connected to a motor, so that only one motor 126 is used by one damper 100.

Specifically, the central shaft 130 may have the same structure as the rotating shaft 125, and the middle part of the outer frame 110 is also provided with a rotating shaft mounting part 116, and the central shaft 130 is mounted in the rotating shaft mounting part 116.

In some embodiments, the first flap 121 of the first damper 1201 is located between the central shaft 116 and the second flap 122, and the first flap 121 of the second damper 1202 is located between the central shaft 116 and the second flap 122.

In the application, two air doors 100 are arranged on the base 41, so that the integration of the air doors 100 is realized, and the problems of time and labor waste during disassembly and assembly due to the fact that the number of air valves is relatively large and the connecting structure is relatively complex in the prior art are avoided; in addition, when a plurality of air valves are independently arranged in the air duct in the prior art, the connecting gaps of the air valves in the air duct are dispersed, and the design of a sealing structure is difficult.
