Therefore, in this embodiment, two notches 328 are specially provided to avoid the mold, so that the inner side surfaces of the first side plate 323 and the second side plate 324 are easy to be demolded.

FIG. 6 is an enlarged view of part VI of FIG. 1; FIG. 7 is a schematic diagram of a damper assembly 010 according to an embodiment of the present utility model at a second viewing angle; fig. 8 is an enlarged view of part VIII in fig. 7. As shown in fig. 6 to 8, the vertical plate 322 forms one wall surface of the wire passing cavity 326, a wire passing gap 327 is formed between one end of the vertical plate 322 far from the connecting plate 321 and the air guide frame 100, the narrowest width of the wire passing gap 327 is larger than the diameter of the wire, and one end of the wire is connected to the driving motor 200 and passes out of the wire passing gap 327 through the wire passing cavity 326.

In the present embodiment, the wire enters the transition chamber 314 from the opening of the mounting chamber 111, passes through the wire passing chamber 326, and then passes out of the wire passing chamber 327. Accordingly, foreign matter, liquid or moisture must first enter the wire passing chamber 326 from the wire passing space 327 and then enter the mounting chamber 111 from the transition chamber 314, through the opening, to contact the drive motor 200. By providing a wire passing portion 320, the driving motor 200 can be better protected from moisture than if a wire passing hole is directly formed in the cover 310. In addition, the wire passing portion 320 can restrict the direction of the wires, so as to avoid being too scattered. The narrowest width of the wire gap 327 is larger than the diameter of the wire, so that the wire can swing along the wire gap 327 to a certain extent, and the wire is prevented from being clamped between the vertical plate 322 and the air guide frame 100 when the motor gland 300 is mounted because the wire gap 327 is smaller.

The connecting plate 321 of the wire passing portion 320 in this embodiment is generally trapezoidal, and the wire passing space 327 is located at the bottom side of the trapezoid, and the width of the entire wire passing cavity 326 is gradually increased along the direction from the opening to the wire passing space 327, so that the wire can swing to a certain extent after passing out from the wire passing space 327, and the wire is convenient to install and wire connection to a certain extent.

Further, the narrowest width of the gap 327 is smaller than 1.5 times of the diameter of the wire, so that serious air leakage caused by overlarge gap can be avoided, and the driving motor 200 is damped.

The wall-mounted air conditioner (not shown in the figure) provided by the embodiment of the utility model comprises the air guide door assembly 010 provided by the embodiment of the utility model, and the air guide frame 100 of the air guide door assembly 010 is fixedly connected to a middle frame of the wall-mounted air conditioner; the wires are connected to the controller so that the controller can control the operation of the driving motor 200. It should be understood that the wall-mounted air conditioner should further include other components for implementing the basic functions of the air conditioner, such as a heat exchanger, a fan, etc., and the arrangement manner and the functional principle of these components may refer to the prior art, which is not described herein again.

In summary, in the embodiment of the present utility model, the cover 310 of the motor cover 300 can limit the driving motor 200 in the installation cavity 111, and the wires pass through the wire passing cavity 326 from the opening of the installation cavity 111 before passing out from the wire passing cavity 327, so that foreign matters, liquid or moisture need to enter the wire passing cavity 326 first and then enter the installation cavity 111 from the opening to contact the driving motor 200. By providing a wire passing portion 320, the driving motor 200 can be better protected from moisture than if a wire passing hole is directly formed in the cover 310. In addition, the wire passing portion 320 can restrict the direction of the wires, so as to avoid being too scattered. The first edge 3211 forms an acute angle with the second edge 3212, and the third edge 3213 forms an acute angle with the second edge 3212. So set up and make connecting plate 321 whole roughly be trapezoidal, trapezoidal bottom one side is used for supplying the wire to wear out, and after such trapezium structure made the wire wear out, also can carry out certain swing, be convenient for installation, wiring to a certain extent. Further, because of the included angle relationship between the first edge 3211, the second edge 3212 and the third edge 3213, the first side plate 323 and the second side plate 324 are in an acute angle relationship with the riser 322, and the wire passing portion 320 is formed by integrally forming the dies, the dies inside the first side plate 323 and the second side plate 324 are inconvenient to remove, so that the dies are avoided by specially arranging the two notches 328, and the inner side surfaces of the first side plate 323 and the second side plate 324 are easy to demould.
