Description

[Detailed Description of the Invention] This invention relates to an oil-burning burner, and in other words, in recent years, many vaporization-type oil-burning burners that gasify and burn fuel have been provided.

This idea is one such idea, in which raw fuel is injected from the combustion outlet into the preheating combustion chamber to start raw combustion, and this initial combustion heats the vaporization cylinder, and when it reaches a high temperature, it is ejected into the vaporization cylinder. The fuel automatically turns into vaporized gas, and the vaporized gas is then combusted.However, all of the raw fuel ejected during this initial combustion is not completely combusted, and excess unburned oil remains as a drain. Unless the drain is removed promptly, complete combustion will not occur, resulting in the generation of carbon and a bad odor.

This idea focuses on this point and uses a simple structure to achieve complete combustion from initial combustion.

Next, to explain the drawings of an embodiment of this invention, 1 is a deep inverted dish-shaped case body with an opening at the top, the inside is a ventilation chamber 2, and a space is formed at the top, while a base plate 3 is attached. ing.

The base plate 3 is shaped like a doughnut, and is recessed with a slight periphery left at the top to open an air supply port 5 in the center. A plurality of six holes 7 are drilled to take in the fuel and discharge unburned oil through a drain, and a plurality of air holes 7 for inflowing combustion air are drilled in the upper part of the inner peripheral side in a bag shape on the back side, and a drain outlet is provided at the bottom. 8 to form a drain storage chamber 9.

A drain pipe 10 has one end attached to the drain outlet 8 and the other end led to the outside from the side of the case body 1.

A combustion cylinder 11 is connected to the air blowing chamber 2 and is attached to the base plate 3, and its upper end is slightly bent inward to open a combustion port 12.

Reference numeral 13 denotes a vaporizer cylinder which is provided in the middle of the combustion cylinder 11 and produces vaporized gas on its inner wall, and has a gas vent 14 in the upper part at the center and a plurality of suction holes 15 around which the vaporized gas and part of the combustion air are taken in. The tapered diaphragm plate 16, which is bored at equal intervals, is open during installation, and is also open at the bottom.

Reference numeral 17 denotes a fuel discharge plate which is positioned to cover the combustion discharge port 18 formed below the carburetor cylinder 13, and its shape is such that a relatively large central hole is bored in the center, and a supporting leg is formed from the inner peripheral edge of the central hole. 19 is in the shape of a plate and stands upright above, and a donut-shaped support plate 20 is positioned outside the air supply port 5 with a space formed therein.
It is fixed.

The combustion discharge plate 17 is rotatable about a motor shaft 23 together with a support plate 20, a support rod 21 supporting the support plate 20, and a fuel spray body 22.

Further, the fuel spray body 22 is located within the vaporization cylinder 13, forming a fuel discharge gap 24 above, and has a fuel discharge pipe 25 opened therein.

Also, a preheating combustion chamber 2 is provided between the combustion tube 11 and the vaporization tube 13.
6. At the start of combustion, main combustion is performed to heat the outer wall of the vaporizer cylinder 13.

27 is a main combustion chamber which is fixed to the vaporizer cylinder 13 so as to communicate with the vaporizer cylinder 13 in a detachable manner, and has a plurality of flame ports 28 on the side.
Attach the partition plate 29 to the lower part of the inside and open the aperture plate 16.
A rectification chamber 30 is formed between the two.

Numeral 31 is a plurality of pipe-shaped preheating burners that communicate with the rectifying chamber 30, and has a plurality of small flame ports 32 facing the outer wall of the vaporization tube 13, so that when gas is combusted, the vaporization tube 13 replaces the preheating combustion chamber 26. Heat.

Further, a fan motor 33 and a fan 34 are integrally attached below the motor shaft 23.

Reference numeral 35 denotes a spark plug located diagonally above the combustion discharge plate 17 in the preheating combustion chamber 26.

This invention is constructed as described above. Next, the operation of one embodiment of this invention will be explained. By starting the fan motor 33, the fan 34, the fuel spray body 22, and the combustion discharge plate 17 also rotate. Combustion air flows into various locations as shown by the arrows.

That is, a part of the combustion air in the blowing chamber 2 enters the drain storage chamber 9 through the inflow air hole 7 formed in the drain storage chamber 9, and is further jetted into the preheating combustion chamber 26 through the hole 6.

Of course, at this time, a portion of the combustion air from the air supply port 5 also flows into the preheating combustion chamber 26.

At the same time, the spark plug 35 starts to discharge sparks, and when fuel is supplied from the fuel discharge pipe 25 to the fuel spray body 22, the fuel flows down the inner wall of the vaporizer cylinder 13 in the form of a thin film due to the circular force &l, and is combusted and released. The fuel flows on the plate 17 and is ejected in the form of mist into the preheating combustion chamber 26 from the combustion outlet 18. The fuel is ignited by the ignition plug 35, which has been spark-discharged in advance, to start raw combustion, and flames and flames are emitted from the combustion outlet 12. Releases heat of combustion.

At this time, all the fuel is not completely burned and some of the fuel flows down to the lower part of the preheating combustion chamber 26 and is discharged through the hole 6 through the drain storage chamber 9, the drain outlet 8, and the drain pipe 10. The drain is sufficiently cooled by the combustion air from the air hole 7.

On the other hand, the outside of the vaporization tube 13 is heated by the combustion in the preheating combustion chamber 26, and the fuel ejected from the fuel spray body 22 is vaporized in the vaporization tube 13 and becomes vaporized gas, which is mixed with the combustion air flowing into the main combustion chamber. Since the fuel flows into the flame port 27 and is ejected from the flame port 28, it is ignited by the flame in the preheating combustion chamber 26 and gasification combustion can be performed.

Further, some of the vaporized gas in the vaporization tube 13 flows into the preheating burner 31 from the rectification chamber 30 and is ejected from the small flame port 32.The flame in the preheating combustion chamber 26, whose momentum has weakened, ignites and starts combustion. 13 outer wall starts heating instead of combustion in the preheating combustion chamber 26.

Further, as a result of this, all the fuel jetted onto the inner wall of the vaporization cylinder 13 is vaporized, and full-scale gas combustion of blue flame is performed.

As described above, this invention is based on a vaporizer cylinder 1 that converts fuel into vaporized gas.
3. In the device, a combustion discharge plate 17 forming a combustion discharge port 18 is provided below, and a preheating combustion chamber 26 for heating the vaporization tube 13 is provided outside the vaporization tube 13.
A plurality of holes 6 are provided at the bottom for both intake of combustion air and drain discharge, and a drain outlet 8 is provided below the holes 6.
and a drain storage chamber 9 having a plurality of inflow air holes 7, the hole at the bottom of the preheating combustion chamber normally supplies sufficient combustion air to the preheating combustion chamber to promote combustion. The unburned oil that grows and cannot be completely combusted can be quickly discharged as a drain, and therefore the hole can be shared, and there is no need to open a special hole, making it easy to manufacture.

Moreover, by drilling an inflow air hole in the drain storage chamber,
The drain is sufficiently cooled, and during normal full-scale combustion, the drain storage chamber acts as an insulator for the main combustion chamber and the preheating combustion chamber, thus preventing the fan motor and fan from heating up.
