PURPOSE:To prevent the diffusion of toilet odor by taking the air in a passenger room and a toilet into an engine through an air chamber by the engine intake action and combusting said air. CONSTITUTION:The air 7 in a toilet 2 reaches a flow inlet 8 through a duct 5 and introduced into an engine by the engine intake action through an air chamber 3, bottom chamber 15, duct 18, and an air cleaner 17 and combusted. When the amount of air supplied from the toilet 2 is not enough, a shutter 16 is switched to intake the outside air 10 from a taking-in port 14, and air is mixed with the outside air 10 and used. Therefore, the diffusion of toilet odor into an urban district, a bus, etc. can be prevented. |
