The rotating shaft of the driving motor 500 is arranged in the supporting hole, so that the rotating shaft of the driving motor 500 is supported, the bearing capacity of the driving motor is improved, and meanwhile, the vibration of the rotating shaft in the working process is reduced, and the working stability of the driving motor is improved.
In order to improve the stability of the movement of the door body 150, the sliding groove is formed in one side of the motor mounting plate 400 facing the driven rack 900, the top of the motor mounting plate 400 is arranged in the sliding groove and is abutted against the top of the sliding groove to support the door body 150. A sliding groove is formed in one side of the driven rack 900 facing the driving gear 600, the extending direction of the sliding groove is the same as the extending direction of the guide groove 910, one side edge of the motor mounting plate 400 is arranged in the sliding groove, the motor mounting plate 400 supports the door body 150 by supporting the driven rack 900, and when the door body 150 moves, the sliding groove moves relative to the motor mounting plate 400. Through the setting of spout for door body 150 obtains more effective support, makes door body 150's removal more reliable and more stable.
In order to improve the moving accuracy of the door body 150, the guide groove 910 is opened along the extending direction of the driven rack 900, the guide groove 910 includes a circumferential section 911 and a radial section 912 which are communicated with each other, and the radial section 912 extends from the circumferential section 911 to a position where the driven rack 900 has teeth. In circumference section 911, door body 150 is along the circumferential direction of panel support 130, in radial section 912, door body 150 is not only along the circumferential direction of panel support 130, still to the radial movement who keeps away from panel support 130, so that door body 150 outwards squints, make door body 150 when closing air outlet 120, still be in same ring face with the panel of cabinet air conditioner, make outside more elegant appearance of cabinet air conditioner, also prevent dust etc. to get into the clearance between panel and the door body 150, thereby improve cabinet air conditioner's performance.
The present invention further provides an air conditioner, which includes an air conditioner indoor unit, and the specific structure of the air conditioner indoor unit refers to the above embodiments, and since the air conditioner employs all technical solutions of all the above embodiments, the air conditioner at least has all beneficial effects brought by the technical solutions of the above embodiments, and details are not repeated herein.
The above description is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention, and all equivalent structural changes made by using the contents of the present specification and the drawings, or any other related technical fields, which are directly or indirectly applied to the present invention, are included in the scope of the present invention.
