Abstract
An air conditioner for a vehicle has a first shaft that drives a first air-mix door in conjunction with being rotated, a second shaft that drives a second air-mix door in conjunction with being rotated, and a rack that interlocks the first shaft and the second shaft with each other. The rack has an elongated shape, thereby a mounting space can be smaller with respect to a rink mechanism. Therefore, an air conditioning unit can be downsized.
Claims7
An air conditioner for a vehicle comprising:
- an air conditioning case that forms an air passage in which air flows toward an inside of a vehicle compartment;
- a cooling heat exchanger that is arranged in the air passage and cools the air flowing in the air passage;
- a heating heat exchanger that is arranged in the air passage on a downstream side of the cooling heat exchanger in an airflow direction and heats the air flowing in the air passage;
- a first cool-air bypass path that is formed in a part adjacent to one end side of the heating heat exchanger, the first cool-air bypass path in which air flows while bypassing the heating heat exchanger;
- a second cool-air bypass path that is formed in a part adjacent to an other end side of the heating heat exchanger, the second cool-air bypass path in which air flows while bypassing the heating heat exchanger;
- a first air-mix door that is arranged in the air passage and adjusts an air volume ratio between a volume of air passing through the heating heat exchanger and a volume of air flowing in the first cool-air bypass path;
- a second air-mix door that is arranged in the air passage and adjusts an air volume ratio between a volume of air passing through the heating heat exchanger and a volume of air flowing in the second cool-air bypass path;
- a first shaft that (i) is connected to the first air-mix door inside of the air conditioning case, (ii) has a first exterior gear outside of the air conditioning case, and (iii) drives the first air-mix door in conjunction with being rotated;
- a second shaft that (i) is arranged parallel to the first shaft, (ii) is connected to the second air-mix door inside of the air conditioning case, (iii) has a second exterior gear outside of the air conditioning case, and (iv) drives the second air-mix door in conjunction with being rotated;
- and
- a rack that is arranged outside of the air conditioning case, is engaged with the first exterior gear and the second exterior gear, and interlocks the first shaft and the second shaft with each other.
