Accessory structure for a vehicle air conditioner

The present invention relates to an accessory structure for vehicle air-conditioners for improvement of interior atmosphere by cleaning an evaporator or feeding aromatic or other functional solvents into the vehicle air-conditioner adapted for taking in air through an air-conditioner air intake route. The accessory structure comprises a solvent ejection means (13) installed in the aforementioned route and a receiving member (17) of a solvent source (A) placed on the compartment side of the vehicle. The solvent ejection means (13) and the receiving member (17) are communicated beforehand through a solvent feed route (15), so that the trouble and the work otherwise unavoidable for connecting the solvent source (A) to the solvent feed route (15) may be spared, permitting the solvent to be instantly fed to the solvent flow ejection means (13).
