Vehicle air conditioner

Abstract

The invention relates to a vehicle air conditioner. The vehicle air conditioner comprises a casing, a wind inlet unit, a filtering unit, a heat exchange unit and a detector, wherein the wind inlet unit, the filtering unit and the heat exchange unit are sequentially arranged in the casing from the upstream side to the downstream side of an air flow direction, and the wind inlet unit comprises an internal circulation wind inlet sucking air from a place in a vehicle chamber under an internal circulation mode, an external circulation wind inlet sucking air from a place outside the vehicle chamber under an external circulation mode, and a wind inlet shifting mechanism for shifting the internal circulation mode and the external circulation mode; the detector is used for detecting the quality of air flowing in the casing, and is used for selectively detecting the quality of air sucked from the place in the vehicle chamber or the quality of air sucked from the place outside the vehicle chamber according to the shifting action of the wind inlet shifting mechanism. According to the vehicle air conditioner disclosed by the invention, the detector which is used for detecting the quality of the air can be arranged in the vehicle air conditioner, so that the structure of the detector can be simplified, and besides, the vehicle layout space is saved.

Description

technical field [0001] The invention relates to the field of air conditioners, in particular to a vehicle air conditioner. Background technique [0002] The vehicle air conditioner is a device used to adjust the temperature inside the vehicle and provide the occupants with a comfortable riding environment. The use of vehicle air conditioners can reduce travel fatigue, create good working conditions for drivers, and play an important role in ensuring safe driving. [0003] With the intensification of air pollution, such as the increasing pollution of PM2.5 particle pollutants, the air quality problem has been paid more and more attention by people. For the people in the car, it is very urgent to be able to effectively detect the air quality inside and outside the car, and then to improve the air quality in the car through the additional function of the car air conditioner. [0004] Various vehicle air quality detectors for detecting the air quality inside and outside the ve...

Problems solved by technology

[0011] However, in the conventional vehicle air quality detector, as described in the above-mentioned Patent Document 1, since the vehicle air quality detector is arranged in the compartment, it needs to pass through the air intake pipe (that is, the air intake pipe 151 and the air intake pipe 151 in the vehicle). The air suction pipe 152 outside the vehicle) takes in air from inside and outside the vehicle, so it will affect the layout of the vehicle

At the same time, since the intake air needs to be switched through the two-way valve 160, the vehicle air quality detector has a relatively complicated structure and occupies a relatively large layout space.
