Adheres to the evaporator. If the air blown by the blower fan comes into contact with this area, it may pick up the odor of the waste products and cause a foul odor to be blown into the room. High temperature or n! Various methods have been proposed to kill the causative agent by cutting off Qi. For example, Utsukai Sho 58-48510
As shown in the publication, a blower fan is provided downstream of the evaporator, a discharge door is provided downstream of the blower fan, the discharge door closes the flow of air to the heater core, and the evaporator is discharged from the outside air inlet. There are some that allow the odor-laden air that flows in through the air to flow back. Further, as shown in Japanese Patent Application Laid-Open No. 62-152918, moisture in the air that has passed through the evaporator is detected, and a discharge door downstream of the blower fan closes the flow of air to the heater core, and the air is released into the outside air. The evaporator is dried by discharging the evaporator.

かかる問題を解決する手段は開示されていない。However, all of these automotive air conditioners are designed to prevent bad odors from being blown into the room when the blower fan is turned on for the first time. Therefore, if the blower fan has been running for a certain period of time and organic matter or fungi have newly adhered to the evaporator, then the air conditioner is turned off.
After the blower fan is idle for a certain period of time after it has stopped, there is a risk that the odor may be carried into the room again due to the fungi that have adhered to the evaporator during the above-mentioned period of operation.
No means are disclosed for solving this problem.

ある。In order to achieve the above object, the present invention provides an air conditioner for an automobile that blows air toward an evaporator by starting a blower fan and blows air into a room through an outlet. A bypass duct is provided between a first passage in between and a second passage in the evaporator and air mix space to communicate both passages, and a bypass duct is provided to communicate air from the blower fan into the first passage. a switching door movable to a first position that leads the bypass duct to the opening and reduces the amount reaching the evaporator; and a second position that closes the opening of the bypass duct and does not impede access to the evaporator; and a switching door that turns on the air conditioner. , OFF switch OFF
The present invention is characterized by comprising a control means for positioning the switching door at the first position in response to an F signal.

A bypass passage is provided between the evaporator 5 and the second passage 16 of the air mix space 8 so as to communicate both passages 15 and 16. Reference numeral 13 denotes a first position 13a and an opening in the bypass passage 12 for guiding the air A from the blower fan 3 into the first passage 15 to the opening 12a of the bypass passage 12 and reducing the amount reaching the evaporator 5. 12a and is movable to a second position 13b where access to the evaporator 5 is not obstructed. Reference numeral 14 denotes a control means, such as an actuator, which positions the switching door 13 at the first position 13a in response to an OFF signal from the ON/OFF switch 17 of the air conditioner 1. Reference numeral 18 is a battery that applies voltage to the actuator 14.

にある。Therefore, according to this structure, the switch 17 is turned on.
and when the blower fan 3 is rotating, the switching door 13 is in the second position 1 as shown by the broken line in FIG.
3b, the opening 12a of the bypass passage 12 is closed, so all of the air A sent from the blower fan 3 (a) reaches the evaporator 5 as shown in FIG. The degree of bad odor at this time is at a certain level, as shown in FIG.

If the application of voltage to the motor (not shown) is stopped,
In response to this OFF signal, the actuator 14, which is a control means, switches the switching door 13 from the second position 13b to the first position 13a as shown by the solid line in FIG. It acts as a baffle plate on the upstream side of the Therefore, the air A flowing toward the evaporator 5 side, which has high air resistance and generates bad odor, decreases as shown in FIG. 2 with the symbol fal.
Moreover, most of the air B passes through the bypass passage 12 with low resistance to the evaporator 5, as shown in FIG.
According to the present invention, the conventional foul odor change curve shown by the broken line in FIG. 3 changes to the bad odor change curve shown by the solid line, so that the bad odor is carried to the indoor PR by the idling blower fan 3. There will be fewer things happening.
尚、前記第二通路１６中に外への排出口を設ければ、臭
気は更に減少することは勿論である。It goes without saying that if an outlet to the outside is provided in the second passage 16, the odor will be further reduced.

動車用空気調和装置とすることが出来る。As described above, according to the present invention, there is provided an air conditioner for an automobile in which air is blown to the evaporator side by activation of the blower fan and blows air to the indoor side through the outlet. a bypass duct provided between a first passage between the evaporators and a second passage of the evaporator and air mix space so as to communicate both roads; and a bypass duct for directing air from the blower fan into the first passage. a switching door that is movable to a first position that leads to the opening of the duct and reduces the amount reaching the evaporator; and a switching door that is movable to a first position that closes the opening of the bypass duct and does not obstruct access to the evaporator; ON, OFF switch OFF
The device is characterized by comprising a control means for positioning the switching door to the first position in response to an F signal, so that when the switch is turned off, the amount of air that comes into contact with the evaporator that generates a bad odor is reduced. Since most of the air flows downstream of the evaporator through the bypass passage where there is less resistance, bad odors are not carried into the room by the idling blower fan, and when the air conditioner is turned off, It is possible to provide an air conditioner for an automobile that does not generate odor.
