Abstract

The invention provides a vehicular air conditioner which comprises an air conditioning box, wherein the air conditioning box comprises a containing space and a foot air outlet channel; the containing space and the foot air outlet channel have connected states; the air conditioning box is further provided with a plurality of air outlets communicated with the containing space, and an air outlet mode conversion device for opening or closing a part of air outlets; the air outlet mode conversion device is arranged in the containing space, and comprises a first rotary shaft, an arc-shaped air door and at least two slab air doors; the arc-shaped air door is fixedly connected with the first rotary shaft and is used for controlling the opening and closing of at least a part of the air outlets; the slab air doors are arranged along the circumferential direction of the first rotary shaft in a spaced manner, and are fixedly connected with the first rotary shaft; and the arc-shaped air door and the slab air doors synchronously rotate with the first rotary shaft. According to the technical scheme, the vehicular air conditioner is compact in structure and small in floor area.

Description

technical field [0001] The invention relates to the field of air conditioners, in particular to a vehicle air conditioner. Background technique [0002] In a car air conditioner, air enters the cabin of a car through multiple air outlets. [0003] In the prior art, a vehicle air conditioner includes an air conditioning box and an air outlet mode conversion device arranged inside the air conditioning box. The air outlet mode conversion device includes a first rotating shaft and a second rotating shaft that is fixedly connected to the first rotating shaft and rotates around the first rotating shaft. A damper. [0004] Above-mentioned automobile air conditioner has following shortcoming: [0005] Because there are many structures inside the air conditioning box, the resistance in the air duct is relatively large in the face air outlet mode or foot air outlet mode, which is not conducive to air outlet; [0006] The car air conditioner opens or closes the above-mentioned multi...
