[0029] The technical solution of the present invention will be further specifically described below through examples and in conjunction with the accompanying drawings. In the specification, the same or similar figure numerals indicate the same or similar parts. The following description of the embodiments of the present invention with reference to the accompanying drawings is intended to explain the overall inventive concept of the present invention and should not be understood as a limitation of the present invention. In addition, in the following detailed description, for ease of explanation, many specific details are set forth to provide a comprehensive understanding of the embodiments of the present disclosure. However, it is obvious that one or more embodiments can also be implemented without these specific details. In other cases, well-known structures and devices are embodied in a pictorial manner to simplify the drawings.

[0030] An overall technical concept of the present invention provides a damper device, which includes a damper left guide rail pressure plate, an damper upper cavity plate, a damper body assembly, a damper right guide rail pressure plate, and an damper lower cavity plate. The damper device can switch the airflow in different channels by moving the valve disc. When the valve disc in the damper device is at the bottom, the airflow flows through the upper channel, causing the machine to operate in full heat exchange mode; when the valve disc is at the top, the airflow flows through the lower channel, causing the machine to operate in internal circulation mode. In addition, the damper guide assembly forms a sliding fit with the damper left guide rail pressure plate and the damper right guide rail pressure plate, respectively, making it easy to pull the valve assembly out.

[0031] The switching of the damper device in the present application can realize the switching of airflow in multiple paths, thereby reducing the number of dampers in the air conditioning equipment and reducing costs. In addition, the connection method of the guide rail and pressure plate of the damper can ensure convenient and fast production, assembly and after-sales maintenance.

[0032] Figure 1 FIG. 1 is a top view showing an exemplary damper device according to the present invention installed in a ventilation duct. Figure 2 FIG. 1 is a schematic view showing a damper device according to an example of the present invention. Figure 3 FIG. 1 is a schematic view showing an exemplary damper device according to the present invention, wherein the damper upper cavity plate and the mounting accessories in the ventilation duct are omitted. Figure 4 yes Figure 3 The main view of the air valve device in. Figure 5 It is a partial view showing the relationship between the air valve device installed in the ventilation duct and each cavity. Figure 6 The figure is a schematic view showing a damper device installed in a ventilation duct.

[0033] like Figure 1-6As shown, the damper device of the present application can be easily and conveniently installed in the desired ventilation duct. The damper device comprises: a damper body assembly 3, which is used to guide the air flow through a valve disc 312 provided thereon. When the valve disc 312 is in a first state, the air is guided from the air inlet cavity b to the air outlet cavity a. When the valve disc 312 is in a second state, the air is guided from the air inlet cavity b to the air supply cavity c, wherein the air outlet cavity a and the air supply cavity c are different cavity spaces; a damper lower cavity plate 5, which is used to support the damper body assembly 3; a damper left guide rail pressure plate 1, which is provided on the damper lower cavity plate 5 and is used to guide and fix one side of the damper body assembly 3; and a damper right guide rail pressure plate 4, which is provided on the damper lower cavity plate 5 and is used to guide and fix the other side of the damper body assembly 3. The damper lower cavity plate 5 can be connected to the air duct 6.

[0034] The damper assembly can switch airflow between different channels by moving the valve disc 312. When the valve disc 312 is in the downward position, air flows through the upper channel, allowing the machine to operate in full heat exchange mode. When the valve disc 312 is in the upward position, air flows through the lower channel, allowing the machine to operate in internal circulation mode. In other words, switching the damper assembly in this application can switch airflow between different channels.

[0035] Specifically, when the valve plate 312 is closed, it can direct the airflow from the air inlet cavity b to the air outlet cavity a. When the valve plate 312 is open, it can direct the airflow from the air inlet cavity b to the air supply cavity c. This can reduce the number of air valves in the air conditioning equipment and reduce costs.

[0036] Figure 7 FIG. 1 is a schematic view showing a damper body assembly of a damper device according to an example of the present invention. Figure 8 FIG. 1 is a schematic diagram showing a damper power device of an exemplary damper device according to the present invention. Figure 9 FIG. 1 is a schematic view showing a damper guide assembly of a damper device according to an example of the present invention. Figure 10 1 is a schematic diagram illustrating the relationship between left and right guide rail pressing plates and left and right guide rail brackets in an exemplary damper device according to the present invention.

[0037] In one embodiment of the present application, Figure 7As shown in Figure 10, the damper body assembly 3 includes a damper power unit 31 and a damper guide assembly 32. The damper power unit 31 includes a motor 311 that provides power for the damper movement, and the damper guide assembly 32 includes a valve disc 312 for guiding airflow. In other words, the motor 311 can drive the valve disc 312 in the damper guide assembly 32 to move, thereby opening and closing the valve disc 312. That is, as shown in the figure, the valve disc 312 can move within the valve frame 313 to open and close the valve. Thus, when the valve disc 312 is closed, it can direct the airflow from the air inlet chamber b to the exhaust chamber a. When the valve disc 312 is open, it can direct the airflow from the air inlet chamber b to the air supply chamber c.

[0038] In one embodiment of the present application, as shown in the figure, the air valve guide assembly 32 further includes a valve frame 313. The valve frame is a U-shaped frame with a central cavity. The valve frame 313 moves within the cavity to guide the airflow. A drive motor 311 can be disposed on the valve frame 313, preferably at a corner of the valve frame 313. The drive motor 311 can drive the valve disc 312, causing it to rotate about its axis, thereby expanding and contracting the valve disc 312. The valve frame 313 has a roughly square cross-section, and the four sides of the valve frame 313 have a certain width and height. The center of the valve frame 313 is open. The width of the valve disc 312 is substantially equal to the width of the inner side of the frame of the valve frame 313, so as to cover the central opening. The valve frame 313 can be made of a plate-like material, and the frame can be provided with transverse and / or longitudinal partitions to increase the strength of the valve frame while reducing its weight.

[0039] In one embodiment of the present application, the damper guide assembly 32 further includes a bottom plate 322, a left guide rail 321, and a right guide rail 324. The bottom plate 322 is bent on both sides, and the left guide rail 321 and the right guide rail 324 are respectively mounted to the left and right bends of the bottom plate 322. Specifically, the left guide rail 321 and the right guide rail 324 are both generally L-shaped strips. The bottom plate 322 is in the shape of a plate with both left and right sides bent upward. The left guide rail 321 and the right guide rail 324 are respectively mounted to the upwardly bent portions, thereby forming a slidable damper guide assembly 32.

[0040] In one embodiment of the present application, Figure 2-4 As shown, the left guide rail 321 is slidably inserted between the air valve left guide rail pressure plate 1 and the air valve lower cavity plate 5, and the right guide rail 324 is slidably inserted between the air valve right guide rail pressure plate 4 and the air valve lower cavity plate 5.

[0041] The damper body assembly 3 slides along the left guide rail 321 and the right guide rail 324 in a direction consistent with the longitudinal direction of the ventilation passage. In other words, the damper body assembly 3 can be installed in the ventilation passage by sliding.

[0042] The damper left guide rail pressure plate 1 can be a double-bent plate, with one side fixed to the damper lower cavity plate 5 and the other side bent upward to be spaced apart from the damper lower cavity plate 5 by one end, thereby forming a structure that guides the movement of the guide rail, as shown in the figure. The structure of the damper right guide rail 324 can be similar to that of the left guide rail 321. That is, the damper right guide rail pressure plate 4 can also be a double-bent plate, with one side fixed to the damper lower cavity plate 5 and the other side bent upward to be spaced apart from the damper lower cavity plate 5 by one end, thereby forming a structure that guides the movement of the guide rail.

[0043] Due to the curved structure of the damper left guide rail pressure plate 1, the left guide rail 321 of the damper guide assembly 32 can slide under the damper left guide rail pressure plate 1 until it is blocked and braked by the damper left guide rail pressure plate 1. Similarly, the right guide rail 324 of the damper guide assembly 32 can slide under the damper right guide rail pressure plate 4 until it is blocked and braked by the damper right guide rail pressure plate 4.

[0044] To ensure smoother movement of the damper body assembly 3, the gap between the lower surface of the damper left guide rail pressure plate 1 and the upper surface of the damper lower cavity plate 5 is equal to the gap between the lower surface of the damper right guide rail pressure plate 4 and the upper surface of the damper lower cavity plate 5. That is, t1 = t2.

[0045] In one embodiment of the present application, the thickness of the left guide rail 321 is smaller than the gap between the lower surface of the left guide rail pressure plate 1 of the air valve and the upper surface of the lower cavity plate 5 of the air valve, and the thickness of the right guide rail 324 is smaller than the gap between the lower surface of the right guide rail pressure plate 4 of the air valve and the upper surface of the lower cavity plate 5 of the air valve.

[0046] More preferably, Figure 10 As shown, the gap between the lower surface of the damper left guide rail pressure plate 1 and the upper surface of the damper lower cavity plate 5 is equal to twice the thickness of the left guide rail 321, and the thickness of the left guide rail 321 is equal to the thickness of the right guide rail 324. In other words, the gap between the lower surface of the damper left guide rail pressure plate 1 and the upper surface of the damper lower cavity plate 5 is equal to twice the thickness of the left guide rail 321, and the gap between the lower surface of the damper right guide rail pressure plate 4 and the upper surface of the damper lower cavity plate 5 is equal to twice the thickness of the right guide rail 324.

[0047] In one embodiment of the present application, to improve the efficiency of air guidance by the damper device, the damper guide assembly 32 further includes a first sealing member 323 and a sealing top plate 325. The first sealing member 323 is disposed on the bottom plate 322 of the damper guide assembly 32, and the sealing top plate 325 is disposed perpendicular to the bottom plate 322 on the damper guide assembly 32, and its width may be greater than the upwardly bent portion of the bottom plate 322.

[0048] The damper assembly also includes an upper damper plate 2, which forms a vent to the exhaust cavity a. In the present application, both the upper damper plate 2 and the lower damper plate 5 are provided with openings in the middle that communicate with the exhaust cavity a and the supply cavity c, respectively. Furthermore, the bottom plate 322 of the damper guide assembly 32 is also provided with an opening in the middle that communicates with the supply cavity c, corresponding to the opening in the lower damper plate 5.

[0049] In the embodiment of the present application, the lower cavity plate 5 of the air valve can be adaptively bent according to the structure of the channel.

[0050] According to another aspect of the present application, an air conditioning device is provided, comprising any one of the damper devices described above.
