るようになっている。2. Description of the Related Art In recent years, there has been an increasing demand for deodorization in a vehicle cabin to improve comfort. To meet this demand, an air conditioner also serving as a deodorizer has been developed. This air conditioner is provided with a blowing unit, a deodorizing unit, and a temperature controlling unit in order from an upstream side to a downstream side in a blowing passage in a duct, so that deodorized and temperature-controlled air is supplied to a vehicle interior. It has become.

きる。The deodorizing means comprises a filter (support) supporting an adsorbent such as activated carbon and a photocatalyst. In this deodorizing means, most of the odorous substances are once adsorbed on the adsorbent,
The adsorbed odorous substance is decomposed by the photocatalyst over time. According to this device, since the odor substance is adsorbed by the adsorbent, it can be deodorized in a short time. In addition, since the adsorbed odor substance is decomposed by the photocatalyst, the adsorbing ability of the adsorbent is not degraded, and the Can be minimized.

よって分解効率が低下するものと推測している。However, in the above-mentioned deodorizing means, the decomposition efficiency (deodorization efficiency) is unstable, and sometimes the regeneration of the adsorbent does not proceed, and the deodorization cannot be performed sufficiently. The present inventors have conducted experiments under various conditions and found that this decomposition efficiency has a correlation with humidity. As shown in FIG. 6, when an experiment was performed using toluene as an odorant, the decomposition efficiency was significantly reduced as the humidity increased. The present inventors speculate that the decomposition efficiency is reduced by blocking the active site of the photocatalyst with water molecules.

A branch passage 1b is connected to the air passage 1a between the blower 3 and the deodorizing unit 4. The upstream portion of the air passage 1a (the portion upstream of the passage connecting portion A between the air passage 1a and the branch passage 1b) and the branch passage 1b are adjacent to each other,
A dehumidifying rotor 11 is disposed over both passages 1a and 1b. The dehumidifying rotor 11 has a large number of air flow passages and carries a moisture absorbent.

る。The operation of the air conditioner having the above configuration will be described. The air introduced from the upstream end of the air passage 1a (outside air or circulating inside air from the passenger compartment or mixed air thereof)
The air flows in the ventilation passage 1a by the blower 3, and the deodorizing unit 4
The temperature is adjusted to a desired temperature by the temperature control means 5, and the air is blown into the vehicle compartment from the air outlet. In the deodorizing unit 4, the odorous substance is once adsorbed on the adsorbent, and the ultraviolet lamp 1
Decomposed by the photocatalyst excited by 3 and deodorized.

とができ、脱臭を良好に行うことができる。The dehumidifying rotor 11 is slowly rotating at a constant speed, and the respective parts are arranged alternately in the ventilation passage 1a and the branch passage 1b with this rotation. When it is arranged in the air passage 1a, moisture in the air passing through the air passage 1a is adsorbed by the moisture absorbent to perform dehumidification. As a result, the air that reaches the deodorizing unit 4 via the blower 3 is dry, and water molecules do not block the active points of the photocatalyst, so that many active points can be left. Therefore, the decomposition efficiency of the odorous substance can be maintained at a high level by the photocatalyst, and the deodorization can be favorably performed.

To the vehicle interior. Ventilation passage 1a by dehumidifying rotor 11
Even if the air passing through the vehicle is dehumidified, the humidity returns to the vehicle interior through the branch passage 1b, so that the humidity in the vehicle interior can be prevented from lowering. The air supplied to the vehicle interior via the branch passage 1b is not deodorized, but does not significantly affect the deodorizing effect. This is because the flow area of the branch passage 1b is smaller than that of the ventilation passage 1a, and the discharge direction of the blower 3 and the direction toward the branch passage 1b are different, so that the amount of air returning to the vehicle interior via the branch passage 1b is small.

When dehumidification of the vehicle interior is required at the time of introducing outside air, the branch passage 1b is communicated with the outside of the vehicle to discharge moisture.
