Abstract

(57) [Summary] [Purpose] Efficiently deodorize each peculiar odor, regardless of whether outside air or vehicle interior air is taken into the vehicle air conditioner. [Configuration] A filter 20 having a function of deodorizing exhaust gas odors, sulfur odors, and nitrogen odors is installed at the outside air inlet 14. on the other hand,
A filter 21 having a function of deodorizing a cigarette odor is installed at the inside air inlet 15.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a vehicle air conditioner.

[0002]

[Prior Art]

 FIG. 2 shows an example of a conventional vehicle air conditioner. In FIG. 2, reference numeral 1 is a housing in which a fan 3, an evaporator 4 and a heater 6 are incorporated. The housing 1 is formed with an outside air suction port 14 for sucking outside air and an inside air suction port 15 for sucking air in the vehicle interior. By switching the inside / outside air switching damper 2, outside air or vehicle interior air is sucked into the housing 1. The outside air or the air in the passenger compartment drawn into the housing 1 by rotating the fan 3 is urged by the fan 3 and cooled in the process of passing through the evaporator 4, and then the heater 6 is driven by the air mix damper 5. It is divided into a flow that passes and a flow that does not pass. The air heated by passing through the heater 6 merges with the air not passing through the heater 6 to become conditioned air of a predetermined temperature, and the face outlet 10 selected by switching the blowout mode switching dampers 7, 8, 9 is selected. , The defrost outlet 11 and the foot outlet 12 are blown into the vehicle compartment from one or more of them.

[0003]

[Problems to be solved by the device]

 In the above conventional vehicle air conditioner, when the outside air is sucked in through the outside air intake port 14, exhaust gas odors, sulfur odors, and nitrogen odors contained in the outside air are blown out into the vehicle interior, and the air inside the vehicle interior intake port 15 is exhausted. When inhaling the air, there was a problem that the odor of smoking caused by the passengers was blown out into the passenger compartment and the air conditioning feeling inside the passenger compartment deteriorated.

[0004]

[Means for Solving the Problems]

 The present invention has been proposed to solve the above problems, and the gist thereof is to provide an air conditioner for a vehicle equipped with an outside air suction port for sucking outside air and an inside air suction port for sucking air in the vehicle interior. In the vehicle air conditioner, a deodorizing filter for exhaust gas odors, sulfur odors, and nitrogen odors is attached to the outside air inlet, and a cigarette smoke deodorizing filter is attached to the inside air inlet.

[0005]

[Action]

 In the present invention, since the outside air is deodorized by passing the exhaust gas odor, the sulfur odor and the nitrogen odor deodorizing filter due to the above configuration, the inside of the air conditioner is discharged from the outside air intake port. Is sucked into. On the other hand, the air in the passenger compartment is passed through the deodorizing filter for cigarette smoke to deodorize the cigarette smoke odor, and is then sucked into the air conditioner through the inside air inlet.

[0006]

【Example】

 One embodiment of the present invention is shown in FIG. In FIG. 1, a filter 20 dedicated to the outside air is attached to the outside air inlet 14, and a filter 21 dedicated to the inside air is attached to the inside air inlet 15. The filter 20 dedicated to the outside air has a function of deodorizing exhaust gas odor, sulfur odor and nitrogen odor contained in the outside air. The indoor air filter 21 has a deodorizing function for cigarette smoke.

Therefore, when the outside air is sucked by switching the inside / outside air switching damper 2, the outside air is passed through the outside air filter 20 so that the exhaust gas odor, the sulfur odor and the nitrogen odor contained in the outside air are efficiently supplied. After being deodorized, it is sucked into the housing 1 through the outside air suction port 14. When the vehicle interior air is taken in by switching the inside / outside air switching damper 2, the vehicle interior air passes through the inside air dedicated filter 21 to effectively deodorize the cigarette odor, and then from the inside / outside air intake port 15 to the housing. It is sucked into 1. Other configurations and operations are similar to those of the conventional one shown in FIG. 2, and corresponding members are designated by the same reference numerals and their description is omitted.

[0008]

EFFECTS OF THE INVENTION In the present invention, since the deodorizing filter for exhaust gas odor, sulfur odor and nitrogen odor is installed in the outside air intake port and the deodorizing filter for cigarette smoke is installed in the inside air intake port, the exhaust gas odor contained in the outside air, Sulfur and nitrogen odors are efficiently deodorized by the deodorizing filter installed in the outside air intake port, and the cigarette odor contained in the cabin air is efficiently deodorized by the deodorizing filter installed in the inside air intake port. .. As a result, the odor peculiar to these can be efficiently deodorized regardless of whether the outside air or the air inside the vehicle is inhaled, so that conditioned air without odor can be blown into the vehicle interior.
