ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to an accessory structure for vehicle air-conditioner for improving the compartment atmosphere by cleaning the evaporator as heat exchanger and others or feeding aromatic or other functional solvent in a vehicle air-conditioner for taking in external air or internal air from an air-conditioning air intake route.
2. Description of the Prior Art
To improve the compartment atmosphere by cleaning the evaporator or feeding aromatic or other functional solvent as described above, a solvent spray nozzle is provided at the upstream side of the heat exchanger in the air-conditioning air intake route, a hose communicating with this nozzle is led out into the compartment, and a container filled with solvent put in a case is installed near the driver's seat or front seat, and a base end of the hose is fitted to the solvent discharge port of the filled container. However, if the filled container is placed near the driver's seat or front seat, since the filled container is intended to obtain a discharge force of the solvent by sealing with packed gas, the filled container may be ruptured in case the packed gas is overheated by exposure to direct sunlight or elevation of compartment temperature.
SUMMARY OF THE INVENTION
It is hence a primary object of the invention to present an accessory structure for vehicle air-conditioner capable of improving the compartment atmosphere by cleaning the heat exchanger or feeding aromatic or other functional solvent, by connecting a solvent feed route to solvent flow injection means provided at the upstream side of the heat exchanger in the air-conditioning air intake route, providing the base end of the solvent feed route with receiving means separated from the solvent source, fixing the receiving means in a specific place in the compartment, and putting in an accommodating space such as glove box and console box not heated to high temperature, while separating the solvent source such as filled container from the receiving means, thereby preventing the solvent source from being ruptured or damaged, and moreover by taking out the solvent source from the accommodating space, when using, and inserting the nozzle into the nozzle guide.
It is other object of the invention to present an accessory structure for vehicle air-conditioner capable of feeding the solvent adequately, by providing the receiving means with a guide for positioning the nozzle of the solvent source when feeding the solvent, so that the nozzle of the solvent source may be positioned at the guide of the receiving means.
It is a different object of the invention to present an accessory structure for vehicle air-conditioner capable of improving the controllability, by forming a taper in the guide, so that the nozzle may be guided into the optimum position for feeding solvent by the taper if the nozzle of the solvent source is brought close to the guide from an oblique direction.
It is a further object of the invention to present an accessory structure for vehicle air-conditioner capable of preventing counterflow of solvent securely, by disposing counterflow preventive means between the guide and the base end portion of the solvent feed route.
It is a further different object of the invention to present an accessory structure for vehicle air-conditioner capable of preventing dust and foreign mater from sticking and invading into the solvent passage of the guide, by disposing closing means for closing the solvent passage of the guide in the inner side of a lid member for covering the guide.
Other objects of the invention will be easily clarified from the description of the embodiments described below.
