Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial field of application> The present invention relates to an oil burning appliance for warm air heating used in general households.

<Prior Art> Conventionally, for example, as disclosed in Japanese Patent Laid-Open No. 56-110817,
Those equipped with an adsorbent that removes offensive odors and harmful substances due to the combustion of oil-burning appliances are known.

<Problems to be solved by the invention> This conventional method is to remove only foul odors and harmful substances by burning, and smoke of cigarettes other than burning, fine floating dust, or fungus of floating molds, mites and mites And pollen could not be removed.

That is, in warm air heating, the air in the room is circulated or agitated by a fan for warm air, so the fine suspended matter that cannot be removed by the prefilter eventually scatters, and a disease caused by this suspended matter occurs. The phenomenon of doing was caused.

It is becoming a big problem especially in families with sick people and small children.

To remove fine suspended matter such as cigarette smoke, mold, mites, mite dung, and pollen, a special air cleaner can be installed separately.

However, in that case, two units, an oil burning instrument and an air purifier, are required, a large indoor space is required, the price becomes expensive, and a plurality of handling units are required, which is also a trouble.

<Means for solving problems. In order to solve the conventional problems, a clean air outlet is provided in front of the outer frame, a warm air outlet is provided below the outer frame, and a warm air fan is provided at the rear of the outer frame. In the horizontal direction, the lower part of the partition is branched into a hot air passage and an upper bypass passage, and the rear end of the partition plate is inclined downward so that it is positioned in front of the hot air fan, and the inside of the bypass passage is quiet. The present invention relates to an oil burning appliance in which an electric dust collecting unit is tilted and provided substantially at a right angle to the wind direction.

<Operation> When combustion is started by a known combustion operation, hot air is discharged from the hot air outlet 7 and, at the same time, the dust collecting unit 1
0 is also energized, and a part of the air supplied from obliquely below the hot-air fan 4 passes through the dust collecting unit 10 which is inclined at a right angle.

When there is tobacco smoke, malodor, mold, mites, mite dung, pollen, etc. which are suspended matter in the air when passing through this, these suspended matter are attracted and attracted to each dust collecting electrode piece 10c.

The purified air is discharged from the clean air outlet 7 ', and the circulation is repeated to clean the indoor air, and the source of the disease is blocked by using the wind of the warm air fan 4.

At this time, the warm air discharged from the warm air outlet 7 tries to rise immediately because of its low specific gravity, but it is pushed forward by the cool air discharged from the upper clean air outlet 7'while being suppressed from above. It is emitted far away, so that the lower heating can be effectively done without immediately raising the warm air.

<Example> 1 is an outer frame, and a combustion chamber 3 having a combustion burner 2 in the lower inside.
Is equipped with.

A fan 4 for warm air is provided at the rear of the outer frame 1, and the combustion chamber 3
Or the heat of the heat exchanger not disclosed is discharged from the hot air outlet 7 in the front through the passage 6 formed by the partition plate 5.

The rear end of the partition plate 5 is slightly inclined downward so as to divert a part of the air of the warm air fan 3 upward, and is positioned in front of the warm air fan 4, and is bypassed with the top plate 8. Road 9
And the clean air is discharged from the clean air outlet 7 ′ provided above the warm air outlet 7.

Reference numeral 10 is an electrostatic dust collecting unit that is inclined to the bypass passage 9 and is installed so as to be substantially orthogonal to the air supplied from obliquely below.

The dust collection unit 10 is a plate-shaped discharge counter electrode 10a connected to a positive power source, and a plurality of square holes 10b each having a side of about 15 mm are regularly opened, and a dust collection electrode piece 10c is formed by bending one side to the downstream side. Further, a discharge electrode 10d, which is needle-shaped from the back side and is connected to the minus power source, is arranged in the central direction of each square hole 10b. When the dust collection unit 10 is energized, a voltage of about DC7kv boosted by a transformer (not shown) is loaded (minus discharge) between the discharge counter electrode 10a and the discharge electrode 10d, and fine dust in the air and cigarette smoke. , Odor, mold, mites, dung dung, pollen, and other floating substances are electrically charged, and attracted and adsorbed to each dust collecting electrode piece 10c.

Reference numeral 11 denotes an opening / closing lid provided on the top plate 8 above the dust collecting unit 10 so that the lid is opened when the dust collecting unit 10 becomes dirty or fails.

Reference numeral 12 denotes a catalyst body that adsorbs a bad odor, a harmful substance, or the like generated at the time of combustion, and when used in combination with the dust collection unit 10, the air cleaning effect is further enhanced.

It should be noted that the dust collection unit 10 is electrically interlocked with combustion and can be independently operated as necessary.

<Effects of the Invention> A clean air outlet 7'is provided in front of the outer frame 1, a warm air outlet 7 is provided below it, and a hot air fan 4 is provided behind it. The partition plate 5 horizontally divides the partition into the hot air passage 6 and the upper bypass passage 9, and the rear end of the partition plate 5 is inclined downward to be positioned in front of the hot air fan 4. Since the electrostatic type dust collecting unit 10 is installed in the bypass 9 so as to be inclined at a substantially right angle to the wind direction, cigarette smoke floating in the air that cannot be removed by the prefilter during heating. , Odor, mold, mites, dung dung, pollen, and other fine dust are reliably removed, and clean air is maintained to prevent the source of disease.

Further, since the dust collection unit bypasses a part of the air by the hot air fan, no special dedicated air blowing means is required, and it is sufficient to obtain clean air, and the hot air volume is not hindered. .

Also, since the clean air outlet is above the warm air outlet, cool clean air is used to hold warm air with a low specific gravity from above.
It is possible to effectively heat the lower part of the room without releasing the warm air far away in the forward direction and immediately raising the warm air.

Also, since the dust collection unit is inclined in the bypass path of the outer frame and is provided at right angles to the wind direction, the entire outer frame can be made compact, and the air supplied to the dust collection unit can be smoothly flowed in with little resistance. Dust efficiency is also good.
