The wall-mounted air conditioner 100 according to the embodiment of the present invention includes a housing 10, the ventilator 20 of the fifth embodiment, a filter screen 40, a dust collector 50, a first hose 70, and a second hose 80. The housing 10 includes a chassis 11 and a face frame 13. The surface frame 13 is covered on the chassis 11, and the surface frame 13 is formed with an air inlet 132. The ventilator 20 is housed in the case and mounted on the chassis 11. The first volute tongue 2112 is formed with an air intake 211m. The second volute tongue 2113 is formed with an air outlet 211n. The third scroll portion 2114 is formed with a suction port 211q. The fourth scroll tongue 2116 is formed with a dust discharge port 211r. The dust suction device 50 is provided on the face frame 13 and connected to the dust suction port 211q. The suction groove 50a faces the filter 40 and communicates with the suction port 211q. The first hose 70 communicates with the air inlet 211m and the outside. The second hose 80 communicates with the dust discharge port 211r and the outside.

The wall-mounted air conditioner 100 according to the embodiment of the present invention not only can automatically remove dust on the filter screen 40, but also can exchange air indoor and outdoor.

In some embodiments, the chassis 11 is formed with a receiving groove 111 and a mounting seat 112. The accommodating groove 111 is used for accommodating a cross-flow fan (not shown) and a heat exchanger (not shown). The mounting seat 112 is located at the left side of the receiving groove 111 and is used for mounting the ventilator 20.

Thus, the space of the wall-mounted air conditioner 100 is saved, and the extension of the body of the wall-mounted air conditioner 100 after the ventilation device 20 is installed is avoided, so that the attractiveness of the wall-mounted air conditioner 100 is influenced.

In some embodiments, the suction device 50 includes a suction rack 51. The dust collection frame 51 includes a support plate 511, an upper panel 512, and a rear cover 513. The upper panel 512 is mounted on the support plate 511. The back cover 513 is connected to the back cover 513 of the support plate 511 and the upper panel 512. The rear cover 513 is attached to the filter screen 40, and the dust suction groove 50a is provided in the length direction of the rear cover 513.

In this way, the dust collection groove 50a has a substantially bar shape, and the dust collection range is wide, so that dust on the filter screen 40 can be absorbed and discharged to the outside through the hose 60.

In some embodiments, the dust extraction 20 further comprises a mounting portion 52, a motor 53, rollers 55, and a sealing strip 55. The mounting portion 52 is hollow and is mounted to one end of the dust collection frame 51. The motor 53 is mounted outside the mounting portion 52. The roller 55 is mounted in the mounting portion 52 and connected to the motor 53. The sealing strip 55 is installed in the dust collection frame 51 and connected with the roller 55. The motor 53 drives the sealing strip 55 to move through the roller 55 so as to adjust the opening size of the dust collection groove 50a.

In this way, since the suction force of the suction groove 50a away from the suction opening 211q is small, the movement of the sealing strip 55 can reduce the opening area of the suction groove 50a away from the suction opening 211q, thereby increasing the suction force of the suction groove 50a away from the suction opening 211q, and ensuring more thorough suction.

In some embodiments, a seal is provided at the junction of the suction device 50 and the suction port 211q.

Thus, the dust suction device 50 and the dust suction port 211q are prevented from leaking out.

In certain embodiments, the seal is silicone.
