PURPOSE:To ensure an immediate interruption of combustion when water within a vapor container leaks through a pin hole into a burner in the water tank with a water heating function which is attached to a warm air type air warmer for humidifying the air within a room. CONSTITUTION:When a motor 39 is started, a fan 45 and rotary cup 47 are driven to rotate so that the fuel from an electromagnetic pump 64 flows through an exhaust pipe 62 and so on and drops into the rotary cup 47. The fuel dropped into the rotary cup 47 is scattered and atomized within the cup 47 by the centrifugal force. The atomized fuel is ignited by an ignition heater 67. Then, the burning is started, and the vapor container 77 provided within a detour 71 of a combustion cylinder 17 is heated by the exhaust gas. The water within the vapor container 77 is evaporated and the resulting steam is injected through an injection grille into the room. If there should be an aperture on the bottom of the vapor container 77, The water leaks into a water reservoir 69 so that an inner cylinder 9 and an attaching leg 22 of a flame holder 21 is electrically short-circuited. As a result of this, a flame rod 23 cannot detect a flame current, and therefore, the operation of the water tank is interrupted. |
