[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air conditioner for a vehicle.

[0002]

2. Description of the Related Art FIG. 2 shows a conventional vehicle air conditioner.
An example is shown. Blower case 1 of blower unit B
When the blower 2 housed inside is driven, the outside air or the inside air is blown according to the switching position of the inside / outside air switching damper 6.
Inhaled into. This air is urged by the blower 2 and sent to the cooler case 3 of the cooling unit C, where it is cooled in the process of flowing through the evaporator 4 housed therein. Next, this air enters the heater case 13 of the heater unit H, is branched by the air mix damper 7, a part of which is heated through the heater 5, the rest bypasses the heater 5, and these are located behind the heater 5. It joins on the flow side to form conditioned air at a predetermined temperature, and is blown into the vehicle interior through an outlet (not shown).

[0003] In this type of vehicle air conditioner, at the start of operation, a bad smell generated from molds and bacteria attached to the surface of the evaporator 4 may be blown into the vehicle cabin along with the conditioned air. To cope with this, a deodorant spray device 8 is provided, the spray nozzle 9 is inserted from between the blower case 1 and the cooler case 3, and the valve (not shown) of the deodorant spray device 8 is opened to spray. A deodorant is sprayed from the nozzle 9 toward the evaporator 4.

[0004]

Since the spray nozzle 9 is inserted between the blower case 1 and the cooler case 3, the tip of the spray nozzle 9 is not stabilized, and therefore, the spray nozzle 9 is uniformly erased over the entire surface of the evaporator 4. The odorant could not be jetted, and the deodorizing effect could not be sufficiently achieved.

[0005]

SUMMARY OF THE INVENTION The present invention has been devised to solve the above-mentioned problems, and its gist is to provide a cooling unit in which an evaporator is housed inside a cooler case. In the air conditioner for a vehicle, a hole is provided at a position deviated from the air inlet of the cooler case by a predetermined distance so as to face a tip opening of the spray nozzle of the deodorant, and the tip of the spray nozzle is provided around the hole. The vehicle air conditioner is characterized in that a trumpet-shaped guide for guiding the deodorant injected from the opening toward the entire surface of the evaporator is provided on the inner surface of the cooler case.

[0006]

According to the present invention, since the above structure is provided, the deodorant sprayed from the spray nozzle is guided by the guide and sprayed uniformly on the entire surface of the evaporator.

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention is shown in FIG. Tip opening 9a of spray nozzle 9 of deodorant spray device 8
Is installed so as to face a hole 10 formed in the cooler case 3. The hole 10 is provided in the inclined portion 3a of the front wall of the cooler case 3 facing the evaporator 4 as shown in the figure.
The tip opening 9 a of the spray nozzle 9 slightly projects into the cooler case 3 and faces the front of the evaporator 4.
A guide 11 is provided around the hole 10 on the inner surface of the cooler case 3, and the guide 11 has a trumpet shape such that the sprayed deodorant can be uniformly sprayed on the entire surface of the evaporator 4.

Thus, the tip opening 9 of the spray nozzle 9
The deodorant sprayed from a is guided by the guide 11 and sprayed uniformly on the entire surface of the evaporator 4, and thus, the malodor generated from bacteria and mold adhered to the surface of the evaporator 4 is sprayed on the entire surface of the evaporator 4. It is effectively eliminated by the deodorant used. Other configurations and operations are the same as those of the conventional one shown in FIG. 2, and corresponding members are denoted by the same reference numerals and description thereof is omitted.

[0009]

According to the present invention, a hole is provided at a position deviated from the air inlet of the cooler case by a predetermined distance so as to face the tip opening of the spray nozzle for the deodorant, and the spray nozzle is provided around the hole. A flapper-shaped guide that guides the deodorant sprayed from the tip opening toward the entire surface of the evaporator is provided on the inner surface of the cooler case. Since it is sprayed uniformly on the entire surface of the evaporator, it is possible to effectively eliminate the odor generated by mold and bacteria attached to the surface of the evaporator.
