Abstract

PURPOSE:To obtain a large effect of deodorization and to prevent a deodorant from being wastefully consumed, by disposing a moisture sensor directly downstream of an evaporator and by controlling such that the deodorant is volatilized and diffused when the above-mentioned sensor detects a humidity with which odor is liable to be generated. CONSTITUTION:In the case of that an operating switch 21 for a blower 3 is turned off while a drive mechanism 17 in a deodrizer 12 closes a shut-off gate 13, when the operating switch 21 is turned on, judgement is made on whether a humidity detected by a moisture sensor 18 disposed directly downstream of an evaporator 4 exceeds a predetermined value (for example, 80%) or not. If it is so, the shut-off gate 13 is held in its close condition but the deorizing operation is not taken. Meanwhile, when a certain humidity which is in such a condition that the evaporator 4 is not completely dried so that odor is most liable to be generated, exceeds a predetermined value, the shut-off gate valve 13 is opened by means of the drive mechanism 17 to feed a deodorant 16 from a communication port 14 through a house 15 into the evaporator 4 within a duct 2 so that the deodrant 16 is volatilized and diffused to effect deodorization.

In such conventional devices, when the operation switch of the air conditioner is turned on, and when the operation switch is turned on and the compressor is turned from on to off, the air inside the deodorizer and the blower duct is removed. The opening/closing door of the communication port that communicates with the flow path is opened for a certain period of time, for example, 10 seconds, to volatilize and diffuse the deodorant to perform the deodorizing effect. That is, this conventional device is used when statistically speaking, the odor attached to the evaporator is most strongly generated, that is, at the beginning of the start-up of the air conditioner;
When the operating switch of the air conditioner is turned from on to off and the compressor stops operating, the deodorizing agent is volatilized and diffused to perform the deodorizing action. Therefore, if the air conditioner is operated continuously, the deodorizing effect will not be performed, and if the odor occurs when the door is not open (for example, if the evaporator is damp due to high humidity such as rainy weather) deodorization is not possible in cases such as or.

うという問題があった。Depending on the situation, the deodorizer may evaporate and diffuse even though no odor may be generated when the air conditioner is initially started or when the air conditioner switch is turned from on to off and the compressor stops operating. Therefore, there is a problem that not only is the deodorant was wasted, but also that the odor of the deodorant fills the vehicle interior when there is no bad odor, causing discomfort to the passengers.

By making it possible to volatilize and diffuse the deodorant only when the vehicle is in a comfortable state, a large deodorizing effect can be obtained, and unnecessary consumption of the deodorant and discomfort to passengers caused by the odor of the deodorant can be eliminated. The object of the present invention is to provide a deodorizing device for an air conditioner for an automobile.

Determine whether If the determination result is OFF, the process moves to step 6, where the drive mechanism 17 holds the opening/closing door 13 in a closed state, no deodorizing action is performed, and both the blower 3 and the compressor are stopped. If the determination result in step 1 is ON, proceed to step 2.

作動すると共にコンプレッサは停止している。It is determined whether the operation switch 22 of the air conditioner 1 is OFF or ON. If the determination result is OFF, proceed to step 3, and determine whether the detected humidity value detected by the humidity sensor 18 immediately downstream of the evaporator 4 is lower or higher than a predetermined value (for example, 80%). . If the discrimination result is low, that is, the humidity is 8
If it is less than 0%, the process moves to step 7, where the opening/closing door 13 is kept closed, no deodorizing action is performed, and the blower 3 is operated while the compressor is stopped. If the determination result in step 3 is high, that is, if the humidity is 80% or higher, the process moves to step 8, in which the drive mechanism 17 opens the opening/closing door 13 and the deodorant 16 flows from the communication port 14 through the hose 15 into the duct. It is said that the odor is volatilized and diffused into the air flow path upstream from the evaporator 4 in the evaporator 2, reaches the evaporator 4 from this part, and the deodorant molecules bond to the odor molecules adhering to the evaporator 4, making them odorless. The deodorizing action is performed, and the blower 3 is operating while the compressor is stopped.

If o, the process moves to step 5, and similarly to step 3, it is determined whether the detected humidity value directly downstream of the evaporator 4 detected by the humidity sensor 18 is lower or higher than a predetermined value (for example, 80%), If the determination result is low, that is, if the humidity is less than 80%, the process moves to step 9, where the drive mechanism 17 closes the opening/closing door 13 and no deodorizing action is performed.
