WARM AIR HEATER

摘要

PROBLEM TO BE SOLVED: To make the humidifying quantity of a humidification water reservoir easily adjustable by making the angle of an evaporation promoting body adjustable while the humidifying quantity of the water reservoir is increased by installing the evaporation promoting body to the reservoir. SOLUTION: A warm air heater is provided with a draft air duct 18 which is formed in the main body case 11 of the heater and connects an air inlet 15 to a hot air outlet 14, a circulating fan 34 and a heat-exchanging section 20 provided in the duct 18, a combusting section 21 which supplies combustion hot air to the heat-exchanging section 20. The heater is also provided with the humidification water reservoir 40 which is provided on the leeward side of the heat-exchanging section 20 in the duct 18 and stores humidified water which is evaporated with hot air and the evaporation promoting body 38 which is attached to the reservoir 40 and has air permeating and water absorbing properties. The angle θ of the evaporation promoting body 38 is made to be adjusted with respect to the vertical direction.
