<p>PURPOSE:To prevent the reduction of the formation quantity of oxygen by allowing the air introducing edge part of an air feeding passage formed onto one side of an oxygen concentrating device to communicate to the air cleaner of an engine and supplying the clean filtered air into the oxygen concentrating device, thus eliminating clogging. CONSTITUTION:In an oxygen concentrating device 70, oxygen concentrating membranes 82 are laminated between the partitioning walls 83 in a hollow body 81, and the air taking-in port 84 of the hollow body 81 communicates to a main duct 75 for taking in air on which an air filter 72, etc. are installed. In the above-described air conditioner, the air introducing side edge part 75a of the main duct 75 communicates to the air taking inport 1a of an air cleaner 1 of an engine E. While, the air taking inport 1a of the air cleaner 1 communicates to the intake manifold 100 of the engine E through a suction pipe 2. Therefore, the filtered air which is removed of dust once by the filter element 1b of the air cleaner 1 is introduced into the main duct 75, and after further filtered by an air filter 72, the air is supplied into the oxygen concentrating device 70.</p> |
