Abstract

PROBLEM TO BE SOLVED: To prevent any dust from being blown out from a hot air outlet when a heating operation is started in an earliest stage of the winter. SOLUTION: A title apparatus is adapted such that a movable louvre 15 movable vertically is mounted on a warm airblowoff outlet 5 of a hot air heater. Hereby, when no heating operation is performed in summer, spring, and autumn, the movable louvre 15 is lowered to close the hot air outlet 5, so that any dust is prevented from entering the hot air outlet 5. Thus, any dust is prevented from being blown out from the apparatus even when heating operation is performed in an early stage of winter, and hence the apparatus is conveniently useable.

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. 5 shows a conventional warm air heating device with an air purifier.
Shown in In FIG. 5, the gas supplied by the burner 1 is burned. There is a combustion chamber 2 for mixing air and combustion gas generated by combustion. 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. Reference numeral 9 denotes a suction port for purifying air, which is located at the upper front of the device. Reference numeral 10 denotes an air purifying filter for removing dust and odor, which comprises a deodorizing section made of activated carbon or the like for adsorbing odors, and a cotton-like or granular charging section for removing dust particles. Attach inside. Reference numeral 11 denotes an air purifying outlet, which is located at an upper part of the apparatus. An air purifying fan 12 is mounted inside the air purifying air passage 13.

Next, the operation will be described. High-temperature combustion exhaust gas 10 generated by burning gas with burner 1
And the convection air 7a that has passed through the convection filter 8 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, and performs heating. The rotation of the air purifying fan 12 causes the air purifying air 14a.
Is sucked in from the air purifying inlet 9, dust and odor are removed by the air purifying filter 10, and the clean air 14b is blown out from the air purifying outlet 11.

[0005] 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-grained charged portion, and the longer the distance through which it passes, the more the particles are attached. The odor is deodorized by adsorbing to a deodorizing section composed of activated carbon or the like.

[0006]

During the heating alone operation in winter or during the simultaneous operation of the air purifier and the heating operation, since hot air is generated from the hot air outlet, dust does not accumulate at the hot air outlet.
However, in summer, spring and autumn, the air purifier operates alone, but does not perform heating operation, so dust accumulates in the hot air outlet, and a large amount of dust is blown out during heating operation in early winter, which is unhealthy. Becomes

[0007]

In order to solve the above-mentioned problems, the present invention has a structure in which a movable louver movable up and down by a stepping motor, a pinion and a rack is attached to a hot air outlet.

According to the present invention, when the heating operation is not performed in summer, spring, or autumn, the movable louver is lowered and the hot air outlet is closed, so that dust does not enter the hot air outlet and the beginning of winter. No dust blows out even when the heater is running.

[0009]

DESCRIPTION OF THE PREFERRED EMBODIMENTS In the present invention, a movable louver movable up and down by a stepping motor, a pinion and a rack is attached to a hot air outlet. When the heating operation is not performed in summer, spring, and autumn, the movable louver is lowered and the hot air outlet is closed, so that dust does not enter the hot air outlet, and even if the heating operation is performed at the beginning of winter, dust is generated. Never blow out.

In addition, two micro switches are provided on the upper and lower portions of the movable louver, and the upper micro switch is turned on when the movable louver is fully opened, and the lower micro switch is turned on when the movable louver is fully closed. Things.
And heating operation can be performed only when the movable louver is fully open,
When the movable louver is fully closed, even if the heating operation is attempted, the heating operation cannot be performed due to the micro switch at the bottom of the movable louver, and the operation is not unsafe.

Embodiments of the present invention will be described below with reference to the drawings.

(Embodiment 1) FIGS. 1 and 2 are cross-sectional views of a gas hot air heating apparatus with an air purifier according to Embodiment 1 of the present invention.

In FIG. 1 and FIG. 2, the hot air heating section and the air purifying section are the same as in the conventional example, and a description thereof will be omitted. Reference numeral 15 denotes a movable louver, and an upper portion is a rack portion 15a.

A stepping motor 16 has a pinion 17 attached thereto, and the pinion 17 is connected to the rack 15a of the movable louver 15.

Next, the operation will be described. When the hot air heater is operated in winter, the stepping motor 16 rotates clockwise as shown in FIG.
5, the movable louver 15 is raised and fully opened. In summer, spring, and autumn, when the air cleaner is operated alone and the hot air heater is not operated, the stepping motor 16 rotates counterclockwise as shown in FIG. 2 and is transmitted from the pinion 17 to the rack portion 15a of the movable louver 15. , The movable louver 15 is lowered and fully closed. When the heating operation is not performed in summer, spring, or autumn, the movable louver 15 is lowered and the hot air outlet is closed, so that dust does not enter the hot air outlet, and dust does not blow out even in the heating operation in the early winter. Absent.

(Embodiment 2) FIGS. 3 and 4 are cross-sectional views of a gas hot air heating apparatus with an air purifier according to Embodiment 2 of the present invention. 3 and 4, the hot air heating unit and the air purifying unit are the same as those in the conventional example, and the description is omitted.
