Air inlet device of vehicle air conditioner

Abstract

The invention discloses an air inlet device of a vehicle air conditioner. The device comprises an outside-vehicle air channel, an inside-vehicle air channel, an air blower, an upper air channel and alower air channel. The air inlet end of the outside-vehicle air channel is provided with an outer air main inlet and an inner air auxiliary inlet, and the outer air main inlet and the inner air auxiliary inlet are controlled to be opened and closed through an outer air damper. The air outlet end of the outside-vehicle air channel is located at the upper end inside an upper impeller. An inner air main inlet is formed in the air inlet end of the inside-vehicle air channel. An outer air auxiliary inlet is formed in a partition plate between the air inlet ends of the outside-vehicle air channel and the inside-vehicle air channel. Opening and closing of the inner air main inlet and the outer air auxiliary inlet are controlled through an inner air damper. The air outlet end of the inside-vehicleair channel extends to the position below the lower air channel and contains a motor component. The motor component is fixed to the bottom of the lower air channel through a flange. An air inlet of the flange communicates the air outlet end of the inside-vehicle air channel and the lower end of the inner side of a lower impeller. The problem that an existing air blower of a double-layer air supply structure is complex in heat dissipation structure and has noise is solved, and independent air inlet inside a vehicle or outside the vehicle can be achieved.

Description

technical field [0001] The invention relates to a vehicle air-conditioning air intake device. Background technique [0002] The existing vehicle air-conditioning air supply structure is mainly a mixed air supply and a double-layer air supply structure with low coverage. [0003] The first is a mixed air supply structure. Its working principle is: the air outside the vehicle enters through the air intake channel, passes through the filter screen, and sends the air out through the air outlet through the impeller. [0004] The main problems of hybrid air supply structure technology are: [0005] 1. The damper used is a single damper structure. If the damper is controlled in the middle stroke, the air inside and outside the car will enter at the same time. During the driving process, the damper of this structure is pushed by the wind pressure, and the damper is easy to swing, which will accelerate the wear of parts. At the same time, there will be abnormal noise; [0006] 2....

AI Technical Summary

Problems solved by technology

[0017] Purpose of the invention: The purpose of the present invention is to provide a vehicle air-conditioning air intake device based on a double-layer air supply structure, which can realize independent air supply of the air outside the vehicle and the air inside the vehicle, and solve the problem of blowers in the existing double-layer air supply structure. The heat dissipation structure is complex, there is a problem of noise during low-speed operation, and it can realize the working mode of the outside of the car or the air outside the car alone.
