First Claim
Patent Images
1. An air conditioner for a vehicle, for blowing air with ions into a vehicle interior, the air conditioner comprising:
- an air-conditioning case that defines therein an air flow passage through which air toward the vehicle interior flows, and has an outlet opening at an upper part of the air-conditioning case and through which the air toward the vehicle interior passes;
a heat exchanger disposed at a lower side of the outlet opening in the air-conditioning case, the heat exchanger being configured to exchange heat between air toward the vehicle interior and a heat-exchange medium; and
an ion generator that includes electrodes configured to generate ions, the ion generator being mounted on the air-conditioning case such that the electrodes are exposed in the air flowing through the air flow passage, whereinthe air-conditioning case has a collision-side wall surface with which an airflow having passed through the heat exchanger collides to be directed upward, and a lateral-side wall surface connected to and laterally adjacent to the collision-side wall surface,the ion generator is disposed at a predetermined position of the collision-side wall surface or the lateral-side wall surface,the ion generator includes one anode and one cathode as electrodes and has properties in which an amount of negative ions generated in the cathode is larger than an amount of positive ions generated in the anode, andthe cathode is disposed on an upstream side of the airflow toward the outlet opening with respect to the anode.

Abstract
An air conditioner for a vehicle includes: an air-conditioning case having therein an air flow passage through which air toward the vehicle interior flows, and an outlet opening formed at an upper part of the air-conditioning case and through which the air toward the vehicle interior passes; a heat exchanger disposed on a lower side of the outlet opening inside the air-conditioning case to exchange heat between air toward the vehicle interior and a heat-exchange medium; and an ion generator that includes electrodes to generate ions. The ion generator is mounted on the air-conditioning case such that the electrodes are exposed in air flowing through the air flow passage. The air-conditioning case has a collision-side wall surface with which the airflow having passed through the heat exchanger collides to be directed upward, and a lateral-side wall surface connected to and laterally adjacent to the collision-side wall surface. The ion generator is disposed at a predetermined position of the collision-side wall surface or the lateral-side wall surface.

5. An air conditioner for a vehicle, for blowing air with ions into a vehicle interior, the air conditioner comprising:
-
an air-conditioning case that defines therein an air flow passage through which air toward the vehicle interior flows, and has an outlet opening at an upper part of the air-conditioning case and through which the air toward the vehicle interior passes; a heat exchanger disposed at a lower side of the outlet opening in the air-conditioning case, the heat exchanger being configured to exchange heat between air toward the vehicle interior and a heat-exchange medium; and an ion generator that includes electrodes configured to generate ions, the ion generator being mounted on the air-conditioning case such that the electrodes are exposed in the air flowing through the air flow passage, wherein the air-conditioning case has a collision-side wall surface with which an airflow having passed through the heat exchanger collides to be directed upward, and a lateral-side wall surface connected to and laterally adjacent to the collision-side wall surface, the heat exchanger includes a cooling heat exchanger that cools the air and a heating heat exchanger that heats the air having passed through the cooling heat exchanger, the air-conditioning case includes a cold-air flow passage formed on an upper side of the heating heat exchanger and through which the air having passed through the cooling heat exchanger flows while bypassing the heating heat exchanger, wherein a portion of the collision-side wall surface and a portion of the lateral-side wall surface facing a core surface of the heating heat exchanger form a space, and the ion generator is disposed at a predetermined position on the collision-side wall surface or the lateral-side wall surface, on a downstream side of the space.
