Air guide mechanism of indoor unit of air conditioner

Abstract

The invention relates to an air guide mechanism of an indoor unit of an air conditioner, which comprises an air guide door and is characterized in that the air guide mechanism further comprises a motion mechanism capable of leading the air guide door to expand, contract, swing and rotate, the motion mechanism arranges a first stepping motor and a second stepping motor in a case, wherein, the first stepping motor is meshed and connected with a swing gear through a first gear mechanism, one end of a swing foot is rotatably connected at one end of the swing gear, a guide pin on the swing foot and a guide slot in an outer cover are in guide matching, the second stepping motor is meshed and connected with a third gear mechanism in the swing foot through a second gear mechanism in the swing gear, a terminal for connecting with the air guide door is mounted in a shaft hole at the lower end of the swing foot, and a gear at the other end in the third gear mechanism and the terminal are connected together, so that air guide blades can carry out telescopic motion and rotate, the guide effect of air is greatly enhanced and the air can be delivered to the further place; furthermore, the range of rotational angle is wider, and dead angles are greatly reduced.

Description

technical field [0001] The invention relates to an air guide mechanism of an indoor unit of an air conditioner. Background technique [0002] At present, the air guide door of the previous product of the air conditioner can only rotate and cannot move outward. Due to the requirements of the temperature field of the indoor unit, there is a large gap between the air guide door of the unit and the upper end of the middle frame. The appearance of the unit is affected. In addition, due to the narrower blades, the pressure head during air supply is smaller and the air supply distance is shorter, which affects the temperature of the indoor temperature field. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an air guide mechanism for the indoor unit of the air conditioner in view of the above-mentioned current situation of the prior art, which enables the air guide vanes to move telescopically and rotate, thereby greatly ...
