Description

[Detailed Description of the Invention] (Industrial Field of Application) This invention relates to a device for dispersing a deodorant into an air conditioning case of an automobile air conditioner.

(Prior art) Among the air conditioners installed in automobiles, especially those equipped with an evaporator unit, such as the
In air conditioners such as those disclosed in Japanese Patent Publication No. 60-28509, the odor generated from the evaporator has recently become a major problem. Therefore, conventionally,
As a means of suppressing the generation of such strange odors, a deodorizing agent has been sprayed into the air conditioning case from the air inlet of the blower unit connected to the evaporator unit.

In addition, as shown in Japanese Patent Application Laid-open No. 58-81817, there is a small case that is attached to the outside of the ventilation path of an air conditioner and is formed by connecting two cases so that they can be opened and closed; a pad impregnated with a volatile deodorizing aromatic agent, a suction side passage and a discharge side passage communicating between the inside of the small case and the inside of the ventilation system passage;
A deodorizing device is described which is provided in the small case so as to be manually operable from the outside and includes a lever that opens and closes both the passages.

(Problem to be solved by the invention) However, in the former case, the deodorizing agent sprayed from the air inlet of the blower unit is blocked by the fan of the blower constituting the blower unit and cannot be effectively applied to the evaporator. There was a problem that it could not be sprayed. In particular, when it is desired to spray the deodorizer directly onto the entire evaporator, the evaporator unit must be removed from the air conditioner, which is time consuming and has the drawback of significantly reducing work efficiency. In the latter case, the deodorizing case containing the deodorant protrudes outside the air conditioning duct (air conditioner case), requiring space and periodically checking the effectiveness of the deodorant. Management is troublesome, as you have to check for the presence and replace it.

Therefore, in this invention, we provide a deodorizing device for an air conditioner that can reliably and easily deodorize by directly spraying the deodorizing agent to each unit or individual location. The purpose is to

(Means for Solving the Problems) Therefore, the deodorant dispersing device for an automobile air conditioner according to this invention has a dispersion port formed in the air conditioning case, and the deodorant sprayed into the air conditioning case through the dispersion port. A nozzle for spraying is provided, and this nozzle has an injection part into which the supply port of a spray can is removably fitted, and when the supply port of the spray can is inserted into the injection part, it opens and when released, it closes and squirts out the deodorant. The air blower is equipped with a blow-out section.

(Function) Therefore, when the supply port of the spray can is inserted into the injection port of the nozzle provided at the spray port, the deodorizer can be sprayed into the air conditioning case from the blowout port through the nozzle. The deodorizer can be sprayed even in areas that cannot be reached from the entrance, so the above objective can be achieved.

(Example) Hereinafter, an example of this invention will be described with reference to the drawings.

In FIG. 1, the automobile air conditioner is constructed by connecting a blower unit 1, an evaporator unit 2, and a heater unit 3. In the blower unit 1, a fan 5a of a blower 5 is housed in a first air conditioning case 4 made of resin. Blower 5
