The novel air inlet baffle can be driven by the rubber track to perform plane telescopic motion, so that the expansion and closing states of the novel air inlet baffle are realized, and the requirements of closing, dust prevention and insect prevention of the air inlet when the air conditioner is shut down are met.
The invention also provides an air conditioner which comprises a panel body 50 and the air conditioner further comprises the air inlet baffle device, wherein the air inlet baffle device is arranged at the air inlet of the panel body 50.
The existing wall-mounted air conditioner has the operation mode that an indoor unit of the air conditioner sucks air from an air inlet at the top, indoor air sequentially passes through a group of air inlet filter screens, an evaporator component and an air duct component which are arranged on a panel body, and then is finally blown out from an air outlet which is sent down after being adjusted by a wind sweeping component and a wind guide component. When the air conditioner is in a shutdown state, the air inlet of the indoor unit is separated from the indoor environment only through the group of air inlet filter screens and is exposed in the indoor environment for a long time, dust in the indoor air can be settled on the air inlet filter screens and the internal structure of the air conditioner, the air inlet filter screens of the air conditioner can be blocked, the air supply health of the air conditioner and the comfortable experience of a user are affected, and the hidden danger that insects and ants damage the air inlet structure of the air conditioner can also exist in the air inlet of the indoor unit.
Therefore, in the prior art, a wall-mounted air conditioner with an air inlet baffle device is generally characterized in that a group of air inlet baffle devices are additionally arranged at an air inlet of an indoor unit, the air inlet baffle devices are positioned above an air inlet filter screen and can be opened and closed according to the running state of the air conditioner, so that the problems of dust settlement, insect damage and the like at the air inlet of the air conditioner in the shutdown state are solved.
The wall-mounted air conditioner with the air inlet baffle device in the prior art is characterized in that an air inlet baffle component of the wall-mounted air conditioner comprises an air inlet cover plate, a pressing plate, a stepping motor, a gear, a rack, a mounting box, a bearing pad, an air inlet baffle and other parts, the mounting box component is assembled in advance in such a way that the mounting box component is mounted together, the mounting box component comprises the stepping motor, the mounting box, the gear, the rack, the bearing pad, a mounting box cover and other parts, then the mounting box component is mounted on the air inlet grille in such a way that the mounting box component is positioned through a pin hole and fixed by screws, and finally the pressing plate, the air inlet baffle, the air inlet cover plate and other parts are mounted on the air inlet grille, and the movable end of the air inlet baffle and the rack in the mounting box component are mounted together through a shaft hole.
