DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hot 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.
There is. An air purifying filter 9 for removing dust and smell is attached inside the filter. The air purifying filter 9 includes a deodorizing section made of activated carbon or the like that adsorbs odor, and a cotton-like or granular charging 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 surface to perform heating.

[0004] Tobacco particles and dust contained in the air adhere to the cotton-like or granular charging portion when passing through the air-cleaning filter 9. The finer the particles, the finer the cotton-like charged portions are, and the longer the distance they pass, the more they adhere.

[0005] The odor is deodorized by adsorbing to a deodorizing section composed of activated carbon or the like.

[0006]

However, in order to improve the dust collection rate and the odor removal rate, the size of the filter for air cleaning should be fine, and the thickness of the filter should be increased so that the area in contact with air can be increased. It is necessary to increase. However, in the above-described air path configuration, when the air purifying filter 9 is mounted as described above, the resistance is large, the pressure loss increases, the convection air 7 decreases, and the temperature of the hot air increases. Therefore, it is not possible to attach a fine filter for air purification with high dust collection performance, and the dust collection performance is low, so that dust and odor cannot be quickly removed.

In order to lower the temperature of the hot air, it is necessary to increase the rotation speed of the convection fan 4, which increases the noise.

Further, during the heating operation, the convection fan 4
As a result, warm air is blown out from one of the hot air outlets 5 to heat the room, so that the room temperature becomes higher near the ceiling, and the room temperature is hardly uniform.

[0009] Further, when the vehicle is operated while maintaining the mutual advantages and each of them can be operated independently, the usability is further improved.

[0010]

It has an air purifying filter for removal and an air purifying unit composed of an air outlet provided on the outlet side of the air purifying fan, so that the warm air heating unit and the air purifying unit can operate simultaneously, and each operates independently. It is also made possible.

According to the above invention, since the air purifying section and the hot air heating section are completely separated, the air purifying filter which has a high dust collection efficiency, sufficiently removes dust and odor, has a fine eye, and has a large surface area. Can be installed, which improves dust collection efficiency and odor removal rate. Therefore, the odor and dust can be quickly removed, and sufficient performance can be ensured even when each is operated independently.
