DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a configuration of a warm air heating device with an air purifier.

[0002]

2. Description of the Related Art FIG. 4 shows a conventional hot air heating device with an air purifier. The burner 1 burns the supplied gas. There is a combustion chamber 2 for mixing exhaust gas generated by combustion with air. Below the burner 1, a convection fan 4 for sending out the hot air 3 is provided. A hot air outlet 5 is mounted in front of the convection fan 4. A convection filter 8 for taking in convection air 7 is provided on the rear surface of the case 6. An air purifying filter 9 for removing dust and smell is attached inside the filter. The air cleaning filter 9 includes a deodorizing section made of activated carbon or the like that adsorbs odors, and a cotton-like or granular dust-collecting section that removes dust particles.

Next, the operation will be described. High-temperature combustion exhaust gas 10 generated by burning gas with burner 1
Then, the convection air 7a that has passed through the convection filter 8 and the air purification filter 9 in the combustion air passage 11 of the combustion chamber 2 is mixed. The mixed hot air is sent out by the convection fan 4 as the hot air 3 from the hot air outlet 5 at the lower front, and is sent out.
Perform heating.

[0004] Tobacco particles and dust contained in the air adhere to the cotton-like or granular dust-collecting portion when passing through the air-cleaning filter 9. The finer the particles, the finer the fluffy dust-collecting portions and the longer the distance they pass, the more they adhere. The odor is deodorized by adsorbing to a deodorizing section composed of activated carbon or the like.

[0005]

Generally, in order to improve the dust collection rate and the odor removal rate of the dust, it is necessary to make the filter of the air cleaning filter fine and make the filter thicker so as to make contact with the air. It is necessary to increase the area to do. However, in the above-described conventional air path configuration, when the above-described air cleaning filter is installed, the resistance is large, the pressure loss is increased, the convection air is reduced, and the warm air temperature is increased.
As a result, the dust collection performance is high and a fine filter for air purification cannot be installed, and the dust collection performance is low.
Dust and smell cannot be removed quickly.

Further, in order to lower the temperature of the hot air, it is necessary to increase the rotation speed of the convection fan, which increases noise.

Further, during the heating operation, since the convection fan blows warm air from one hot air outlet to heat the room, the room temperature becomes higher near the ceiling, and the room temperature is hardly uniform.

[0008] Further, even if an attempt is made to add a full-fledged air purifying function to the warm air heater, the height is increased or the depth is increased, so that the apparatus is not compact.

[0009]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention provides an air purifying unit for heating a hot air generated by operating a convection fan and burning the air to heat the air. And an air purifying unit composed of an air purifying filter and an air purifying filter.

According to the present invention, the fan for air cleaning is provided with a double-shaft sirocco-type fan in the motor, so that it is resistant to pressure loss, can obtain a large air volume, and sufficiently removes dust and smell. It is possible to install an air purification filter that has a high dust collection efficiency and a fine surface area, and improves the dust collection efficiency and odor removal rate.
Further, when a sirocco fan having blades on both shafts is used to provide an air purifying section above the hot air heating section, 200 m
It can be realized by increasing the height by about m, and a compact shape can be realized.
