In some embodiments, the position of the rotary motion trace of the inwall correspondence arc plate 2115a of the second snail tongue 2113 is provided with and the gusset 2113e of arc plate 2115a laminating, when arc plate 2115a is in described primary importance, one end of arc plate 2115a engages with gusset 2113e, and the other end is fitted with the section of intersecting of described second snail tongue 2113 and the inwall of the 3rd snail tongue 2114.

So, improve arc plate 2115a and be in the sealing of air interchanger 20 during primary importance.

In some embodiments, the position of the rotary motion trace of the inwall correspondence arc plate 2115a of the 3rd snail tongue 2114 is provided with the draw-in groove 2114a coordinated with arc plate 2115a. When arc plate 2115a is in the second position, one end of arc plate 2115a snaps in draw-in groove 2114a, and the other end is fitted with the section of intersecting of described second snail tongue 2113 and the inwall of the 3rd snail tongue 2114.

So, improve arc plate 2115a and be in the sealing of air interchanger 20 during the second position.

The hanging air conditioner 100 of this utility model embodiment includes the air interchanger 20 in housing 10, embodiment four, filter screen 40 and dust exhaust apparatus 50. Housing 10 includes chassis 11 and surface frame 13. Surface frame 13 is located on chassis 11, and surface frame 13 is formed with air inlet 132. Air interchanger 20 is contained in housing and is installed on chassis 11. First snail tongue 2112 is formed with dust-exhausting port 211r. Second snail tongue 2113 is formed with gas outlet 211n. 3rd snail tongue 2114 is formed with suction port 211q. Dust exhaust apparatus 50 is arranged in surface frame 13 and is connected with suction port 211q. Dust-absorbing groove 50a is towards filter screen 40 and connects suction port 211q.

The hanging air conditioner 100 of this utility model embodiment forms suction when the blower fan of air interchanger 20 is rotated in a second direction, at dust-absorbing groove 50a, dust on strum 40 is then discharged to outdoor, realize the effect of the described automatic dust out of hanging air conditioner 100, thus improving the satisfaction of user.

In some embodiments, dust exhaust apparatus 50 includes dust suction frame 51. Dust suction frame 51 includes gripper shoe 511, top panel 512 and back shroud 513. Top panel 512 is installed in gripper shoe 511. Back shroud 513 connects the back shroud 513 of gripper shoe 511 and top panel 512. Back shroud 513 is attached on filter screen 40, and dust-absorbing groove 50a is located on the length direction of back shroud 513.

So, dust-absorbing groove 50a is substantially bar shaped, and dust suction scope is big, it is possible to absorbs the dust on filter screen 40 and is discharged to outdoor by flexible pipe 60.

In some embodiments, dust exhaust apparatus 20 also includes installation portion 52, motor 53, roller 55 and sealing strip 55. Installation portion 52 is installed on dust suction frame 51 one end and hollow. Motor 53 is installed on outside installation portion 52. Roller 55 is installed in installation portion 52 and is connected with motor 53. Sealing strip 55 is installed in dust suction frame 51 and is connected with roller 55. Motor 53 drives sealing strip 55 to move to regulate the size of dust-absorbing groove 50a opening by roller 55.

So, owing to dust-absorbing groove 50a is less away from the suction at suction port 211q place, sealing strip 55 motion can reduce the dust-absorbing groove 50a aperture area away from suction port 211q, thus increasing the dust-absorbing groove 50a suction away from suction port 211q place, thus ensureing that dust suction is more thorough.

In some embodiments, dust exhaust apparatus 50 is provided with sealing member with the junction of suction port 211q.

So, it is prevented that dust exhaust apparatus 50 and suction port 211q to after leak out.

In some embodiments, sealing member is silica gel.

When the hanging air conditioner 100 of this utility model embodiment is in cleaned model, spool 2115 rotates closes gas outlet 211n, and blower fan is rotated in a second direction, and dust-absorbing groove 50a forms suction by the dirt absorption on filter screen 40, and dust is discharged to outdoor by flexible pipe 60. When hanging air conditioner 100 is in ventilatory pattern, spool 2115 rotates closes suction port 211q, blower fan is rotated in a first direction, and dust-exhausting port 211r (being now air inlet) air outdoor sucks air, delivers to indoor from gas outlet 211n after flowing through the second snail tongue 2113. Achieve hanging air conditioner 100 and integrate dust-absorbing function and ventilatory so that the structure of hanging air conditioner 100 is compacter.
