In this apparatus, the nozzle 5 2, by eruptive water and drugs to Ebapore evening 5 1 surface, removing the mold Ya dust Ebaboreta 5 1 surface, is to be able to prevent the malodor _β

However, since the cleaning liquid ejection nozzle disclosed in the above-mentioned Japanese Utility Model Application Publication No. 62-994417 is a surface-fixed type, the jetted water and chemicals are supplied only to the surface of the injection area of the nozzle. Provide the entire surface of the evaporator, such as It is difficult to supply. Therefore, it is difficult to completely remove and sterilize deodorants, because the recesses and the back surface of the back surface to which the washing water and the chemicals are not supplied are not removed.

 In addition, the generation of tools is caused not only by the mold on the evaporator surface, but also by the adhesion of mold and dust in the suction duct from inside the vehicle to the blower fan T).

 For this reason, in cases where mold and garbage are extremely attached, the entire air conditioning system is disassembled and the evaporator, heater, duct, etc. are thoroughly washed to prevent the generation of bad odors.

 Such S is a problem that occurs not only in an empty device equipped with an evaporator for recirculation but also in a vehicle having only a heater without an evaporator.

 Therefore, the present invention is intended to solve the above-mentioned problems in preventing bad tools, and it is possible to relatively easily and efficiently remove bad tools caused by mold or the like generated on the surface of an air conditioner such as an evaporator. The aim is to provide possible means. M indication of invention

 In order to achieve the above object, the present invention provides a ventilation fan having an M outlet in a vehicle, a fan for blowing air, a cooling evaporator downstream of the fan for blowing air, a cooling evaporator, and a heater for heating. In particular, in a vehicle air conditioner equipped with a heat exchanger such as the above, a deodorant liquid supply device that sprays deodorant liquid to the outlet located upstream of the fan for blowing air in front of E was used. And

Here, as the pre-ia deodorizing liquid supply device, an ultrasonic mist generating / concealing device that converts the deodorizing liquid into a mist can be used. Mist conversion means that it is possible to make the deodorant liquid particles s-shaped or hazey, and it is possible to use a sa-compatible ultrasonic filter. S In addition to washing water, deodorizing liquids that are plant-based deodorizing tt and that are odor-free, equipped with disinfecting tools, sterilization, and power-proof flicker, and that provide a safe and good shadow β to the human body Can be used. In particular, «[Excellent deodorizing ability, as a natural vegetable deodorant containing phytoncide, trade name PCS-500 (manufacturer, SATEC Corporation, distributor, SATEC Corporation and Mitsubishi Chemical Corporation) Corporation) can be used.

 By installing the beak outlet of the deodorant liquid supply device in the upstream area of the blower fan, the deodorant liquid supplied into the ventilation passage from the jet port by the suction force (negative pressure) of the blower fan is drawn into the blower fan. Here, since the deodorant liquid is provided for downstream filling in a sufficiently expanded state, the entire air conditioner and the interior of the vehicle can be made to have a deodorant liquid atmosphere. In particular, by making the quenching liquid into a mist, suction and diffusion by the blower fan can be performed more reliably.

 Phytontide is a ffi compound such as alloids, glycosides, resins, organic »and tannin BI contained in trees and other plants. It suppresses the proliferation of bacteria such as Salmonella and the like, and wraps harmful substances in the air such as nitrogen oxides.
