ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to air intake passage cleaning method and its apparatus for cleaning the air intake passage of intake and exhaust apparatus such as air conditioning passage of air conditioner for conditioning the air in, for example, building, ship, aircraft, automobile, train, or other room.
2. Description of the Prior Art
Hitherto, the air conditioner incorporates, in its housing, a heat exchanger which acts as an evaporator in cooling and a condenser in heating, and the heat exchanger and air intake passage are likely to be contaminated, and germs and molds are formed in the process of heat exchange of the indoor air containing dust, moisture, cigarette smoke or the like taken in from the air suction port provided in the housing.
When air conditioning is operated in such state, the sanitation in the room is spoiled, and the indoor environments deteriorate due to generation of offensive smell.
SUMMARY OF THE INVENTION
It is hence a primary object of the invention to present an air intake passage cleaning apparatus capable of cleaning the air intake passage and heat exchanger securely and improving the indoor environments, by comprising supplying means for supplying cleaning solvent, together with compressed air, to the heat exchanger side from the blow-out port through the air intake passage.
It is other object of the invention to present an air intake passage cleaning apparatus capable of improving the ease of cleaning operation, by disposing the above supplying means in an arbitrary blow-out port out of plural blow-out ports.
It is a different object of the invention to present an air intake passage cleaning apparatus capable of cleaning the entire region and heat exchanger securely even if the air intake passage is long in the passage length, by disposing the above supplying means in the blow-port port at the remotest position from the heat exchanger out of plural blow-out ports.
It is another object of the invention to present an air intake passage cleaning apparatus capable of cleaning the air intake passage and heat exchanger securely and improving the indoor environments, by cleaning the air intake passage by supplying compressed air and cleaning solvent from the blow-out port to the heat exchanger side through the air intake passage.
It is a further object of the invention to present an air intake passage cleaning apparatus capable of preventing the fluid after cleaning from flowing out from other blow-out port and enhancing the cleaning efficiency, by blocking other blow-out ports with a clocking member when supplying air and cleaning solvent from a specific blow-out port.
It is still other object of the invention to present an air intake passage cleaning apparatus capable of obtaining sanitary environments, by moving a cleaning and wiping element provided in the air intake passage by moving means, thereby cleaning and removing securely and cleanly the dirt depositing inside the air intake passage, for example, by the cleaning power of the cleaning solvent impregnated or adhered to the cleaning and wiping element.
It is a further different object of the invention to present an air intake passage cleaning apparatus capable of moving all cleaning and wiping elements together to the blow-out port side and cleaning and removing the dirt depositing inside the air intake passage in a short time, by blocking the other blow-out ports except for a specific blow-out port, when applying a transfer pressure supplied from the air supplying means to the cleaning and wiping elements provided in the air intake passage.
It is a still further different object of the invention to present an air intake passage cleaning apparatus capable of wiping and removing the dirt depositing inside the air intake passage by the cleaning and wiping elements, and freely changing the wiping position by the cleaning and wiping elements depending on the position and area of contamination, by towing and manipulating linear traction members linked to the cleaning and wiping elements.
Other objects of the invention will be clarified from the following description of the embodiment.
