DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a warm air heater for heating indoor air by mixing indoor air and combustion gas.

[0002]

2. Description of the Related Art Various types of hot air heaters of this type have been proposed, and some of them are used for hot air heating by burning fuel gas obtained by evaporating gas or kerosene. Hereinafter, a hot air heater used for hot air heating by burning this liquid fuel gas will be described as an example. Such a hot air heater is shown in FIG.
It is configured as shown in FIG.

That is, first, fuel is supplied from the cartridge tank 2 to the tank 1, and the fuel in the tank 1 is supplied to the burner section 4 by the pump 3 and is burned there.
The generated combustion gas is guided upward by a combustion tube 5 disposed so as to cover the periphery of the burner unit 4, and a duct 6 covering the combustion tube 5 supplies the indoor air from a blower 7 including a propeller fan and a blower motor. The louver 9 is mixed with the air flow and
The air is discharged as warm air through the air and used for heating. When the fuel supply amount is adjusted by changing the driving frequency and applied voltage of the pump 3, the primary air amount increases and decreases accordingly, and the combustion amount is changed while the fuel-to-air ratio is kept constant. Is available.

[0004]

However, in the hot air heater having such a configuration, the tank 1 is inevitably placed due to the disposition of parts.
In some cases, it is necessary to place components such as the cartridge tank 2 and the control board on the side of the main body case, that is, on the side of the duct 6, and in this case, it is necessary to arrange the air outlet 7 almost over the front width of the main body case. And the side of the main body case on which the components are placed, for example, the front surface of the side of the duct 6, is closed. Therefore, there is a disadvantage that it is difficult to balance the left and right of the hot air blowout, it is not possible to blow out the entire front surface of the main body case wide, and it is not possible to improve the feeling of heating.

In order to solve such a problem, the characteristic of air flowing along the wall surface due to the viscosity of the air flow is conventionally used to apply hot air to the side of the outlet of the duct 6 as shown in FIG. A method has been proposed in which a guide 10 is provided in the side direction to guide the flow, or a small room 11 is provided on the side of the duct 6 as shown in FIG.

However, even with such a configuration, the hot air has a low flow velocity, is low in density and low in viscosity due to the hot air, and has a blower 7 comprising a propeller fan and a blower motor.
The flow of the warm air is not laminar because of the use of the air flow. Therefore, the amount of air flowing along the wall surface is small due to the viscosity of the air flow, and the guide 10 is provided in the side direction to guide the flow of the warm air described above. Even in the method, and in the method in which the small room 11 is provided on the side of the duct 6 described later, the effect is not so large, it is not possible to blow out wide enough to the entire front surface of the main body case, and the feeling of heating is sufficiently good. There was a drawback that could not be done.

[0007] The present invention has been made in view of the above problems,
An opening is provided in the vicinity of the outlet of the duct 6, and a closing means for freely opening and closing the opening for taking out hot air at the side of the duct is provided, so that the outlet of the hot air is wider than the outlet of the duct 6 or wider than the outlet. By switching freely,
The purpose is to improve the feeling of heating.
