As described above, according to the present invention, the following effects can be obtained.

Since the electric heater is disposed in the space through which most of the mixing air passes between the combustion cylinder and the side wall of the hot air heat exchange chamber constituting the hot air heat exchange chamber, effective heating of the indoor air is achieved. Sterilization can be performed.

Further, an electric heater is provided in the mixing section, and air for mixing between the combustion cylinder and the side wall of the hot air heat exchange chamber constituting the hot air heat exchange chamber is led to the electric heater provided in the mixing section. Since the wind direction guide is provided, in addition to effective sterilization of the indoor air by heating, unburned gas generated from the burner and flowing from the combustion cylinder to the mixing section can be oxidized and thermally decomposed to perform odorless heating.

A filter is provided in a space through which air for mixing passes between the combustion cylinder and the side wall of the hot air heat exchange chamber constituting the hot air heat exchange chamber, and the filter is heated and sterilized by an electric heater. Therefore, the bacteria and the like collected by the filter are heated by the electric heater for a sufficient time, so that the heat sterilization can be surely performed.

Further, since fins made of a material having good heat conductivity are provided on the side wall portion of the hot air heat exchange chamber, the warm air heated by the electric heater disposed between the side wall of the hot air heat exchange chamber and the combustion tube is provided. By increasing the surface area of the side wall of the heat exchange chamber and increasing the contact area with the mixing air passing therethrough, sterilization of the sucked indoor air can be performed more reliably.

Further, since fins made of a material having good heat conductivity are provided on the surface of the combustion cylinder as a means for promoting heat sterilization, the surface area of the combustion cylinder which is heated to a high temperature by the heat of the burner increases,
Since the contact area with the mixing air passing here also increases,
The inhaled room air can be sterilized economically without providing a new heat source such as an electric heater.

Further, since the electric heater is provided with fins made of a rod-shaped material having good heat conductivity, the heat of the electric heater also raises the temperature of the fins, thereby increasing the contact area with the mixing air passing therethrough, and The efficiency of the sterilized indoor air is improved.
