[0002]

2. Description of the Related Art Conventionally, various types of combustion devices of this type have been proposed. FIG. 4 shows an example thereof, but this type is configured to save power. To explain the configuration, an electromagnetic pump 52 is attached to the upper surface of the oil pan 51, and one end of an oil feed pipe 53 is connected to the electromagnetic pump 52. The other end of the oil feed pipe 53 is connected to a circular carburetor 54, and the oil sent from the oil pan 51 by the electromagnetic pump 52 is carburetor 54 and carburetor lid 54.
It is sent to the vaporization chamber 55 constituted by A.

The vaporization chamber 55 is a slot 5 at the center of the vaporization chamber.
6 is formed to surround the heater 6, and the heater 57 is
And a communication passage 59 communicating with the nozzle 58 is provided on the side opposite to the slot 56 with respect to the inlet of the oil feed pipe 53 of the vaporization chamber 55.

A return pipe 60 is attached to the nozzle 58, and an electromagnetic solenoid 61 is connected to the other end of the return pipe 60. The electromagnetic solenoid 6
The side opposite to the return pipe 60 of No. 1 is communicated with the oil receiving tray 51, and the electromagnetic solenoid 61 is provided with a needle 62 for opening and closing the nozzle hole 63 of the nozzle 58.

A burner portion 66 is provided on the upper portion of the vaporizer lid 54A provided so as to cover the outlet 65 of the throat 56, and the burner portion 66 is provided in close contact with the vaporizer lid 54A. The flange 68 at the top of the vessel 54 is configured to be heated.

In the above structure, the vaporizing chamber 55 is provided in the heater 5.
7 is heated to a predetermined temperature by 7 and vaporizes the oil entering from the inlet of the oil feed pipe in the process of reaching the communication passage 59. The vaporized gas flows downward through the communication passage 59 at the bottom of the vaporization chamber and reaches the nozzle 58.

When the vaporizer 54 reaches a predetermined temperature, the needle 62 is opened and the vaporized gas is discharged into the nozzle hole 63.
Eject more. The vaporized gas vigorously flows toward a slot 56 provided in the center of the vaporizer, and in response thereto, primary air is entrained from between the lower end 69 of the slot and the nozzle 58, and from a slot outlet 65 to a burner section 66. The mixture is mixed inward and ignited on the outer periphery of the burner portion 66 to generate a combustion flame 67 for combustion.

On the other hand, the carburetor 54 has its upper flange 68.
Is heated by the combustion flame 67, and the burner section 6
The vaporizer lid 54A is heated by heat conduction from 6,
Due to the heat recovery action, vaporization is continued even if the heater 57 is not energized, and combustion is continued, that is, self-combustion, and power saving is achieved.

[0009]

However, the above-mentioned conventional structure has the following problems. That is, the slot
Since the vaporizer 54 is formed so as to surround the outer circumference of the hood 56, the vaporizer 54 itself becomes large, and
4 is difficult to make compact and the manufacturing cost is high, and moreover, the heat capacity of the carburetor 54 increases and it takes time to heat the carburetor 54 to a predetermined temperature at the start of operation, that is, the time until ignition becomes long. There was a problem.

Further, it is difficult to secure the airtightness inside the carburetor 54. Therefore, when the carburetor 54 is actually commercialized, the carburetor 54 is formed by joining a plurality of pipes and connecting it with a slot. It is necessary to perform complicated processing such as casting by integrally forming with 56, and when the pipe is not cast, the vaporizer 54 must be covered with the vaporizer lid 54A and the sealing material must be applied between them. In addition, the manufacturing cost is increased and airtight leakage or deformation occurs due to variations in mass production, and it is difficult to ensure sufficient quality.

Further, the carburetor 5 surrounding the slot 56.
Since No. 4 has a circular shape, it becomes difficult to fill a vaporization element for smooth vaporization of oil to suppress the production of tar in the vaporization chamber, and the vaporization element selection is limited. However, there is a problem that the performance cannot be sufficiently improved.

On the other hand, in the above-mentioned conventional structure, since the nozzle 58 wraps around the lower surface side of the vaporizer 54 and is separated, the vaporizer 54 and the nozzle 58 are in the form of being largely separated thermally, and the nozzle 58 is provided. As the temperature of the vaporization chamber 55 decreases and the nozzle 58 is located below the vaporization chamber 55, the vaporized gas that has become high temperature remains in the upper portion of the vaporization chamber 55, and the low-temperature unvaporized gas or oil is in the lower communication passage. There is a problem that the vaporized gas does not easily flow through the nozzle 58 via 59, and the vaporized gas easily turns into a tartle from the communication passage 59 to the nozzle 58 due to the low temperature gas and the low temperature of the nozzle 58. It was

Therefore, even if the vaporization chamber 55 or the communication passage 59 from the vaporization chamber 55 to the nozzle 58 is to be filled with a vaporization element for promoting vaporization, the vaporizer 5 surrounding the slot 56.
Since 4 is a circular shape, it is difficult to fill such a vaporization element into the vaporization chamber, and there is a problem that the vaporization element selection is limited and it is not possible to sufficiently improve the performance such as the tar property. It was

Further, in the above conventional structure, the primary air suction amount can be increased as the nozzle 58 is separated from the carburetor 54, but the position of the nozzle 58 cannot be lowered so much due to the tarring problem. There is also a problem in that the air intake area determined by the positional relationship between the nozzle 58 and the inlet of the slot 56 cannot be increased, and the combustion performance of the burner is restricted because the primary air for combustion cannot be taken sufficiently. . In addition, since the slot 56 and the carburetor 54 are integrally formed, the lower shape of the slot 56 is limited to the straight shape due to the molding restrictions and the like, and the primary air amount greatly affected by the throat shape increases. There was a problem that measures and noise reduction measures could not be taken sufficiently.

The present invention has solved the above-mentioned problems, and has as its first object to shorten the ignition time while making the most of the advantage of power saving by heat recovery, and to reduce the cost by facilitating processing and downsizing. The second purpose is to further suppress the tar formation of the vaporized gas, and the third purpose is to
A fourth object is to improve the combustion performance by enlarging the opening for intake of primary air.

[0016]

In order to achieve the above object, the present invention has a vaporizing section for vaporizing fuel, a heater for heating the vaporizing section, a nozzle for ejecting the vaporized gas in the vaporizing section, The burner is provided with a burner portion for burning the gas ejected from the nozzle, and a burner receiving seat for holding the burner portion. The burner receiving seat is a flat plate having a vaporization portion and a vaporization portion from the vaporization portion. A nozzle mounting part for ejecting gas and a communication passage from the vaporizing part to the nozzle mounting part are integrally formed, and an opening for sucking primary air by an ejector action of the gas ejected from the nozzle is formed and covers this opening. Thus, the burner portion is covered with the burner portion, and the throat is arranged in the burner portion.

The burner receiving seat is arranged substantially horizontally, the nozzle mounting portion is integrally formed on the upper surface of the burner receiving seat, and the vaporizing portion is integrally formed on the lower surface side of the burner receiving seat. And a burner mounting portion is formed on the outer periphery of the upper surface of the burner receiving seat and a nozzle mounting portion is formed in the central portion, and A structure in which a linear vaporization portion is formed between the nozzle mounting portion and the burner mounting portion and a heater is provided along the vaporization portion and the burner mounting portion, or the burner described above. A heater is mounted on the outer periphery of the receiving seat, and a nozzle mounting portion is formed in the center thereof, and a vaporizing portion communicating with the nozzle mounting portion via a communication passage is integrally formed on one side of the nozzle mounting portion. And on the opposite side from the burner mounting part to the nozzle mounting part It is constituted of forming an opening for intake primary air leaving the building ribs.

[0018]

According to the present invention, since the vaporizing portion, the nozzle mounting portion, and the primary air intake opening are integrally formed in the burner receiving seat as described above, and the throat is arranged in the burner portion covered by the burner receiving seat, the vaporization is performed.

Further, in the case where the nozzle mounted on the nozzle mounting portion is located above the vaporizing portion, the vaporized gas vaporized in the vaporizing portion smoothly moves toward the nozzle above the vaporizing portion. The vaporized gas, which is a completely vaporized high-temperature vaporized gas, flows toward the nozzle so that the vaporized gas hardly tarifies, and the tar performance can be improved.

Further, in the case where the vaporizing part is integrally formed between the burner mounting part provided with the heater for the burner receiving seat and the nozzle mounting part, the nozzle mounted in the nozzle mounting part is attached to the vaporizing part and the burner mounting part. It is possible to maintain the temperature at a high temperature by the conduction heat from the burner portion mounted on the substrate, and it is possible to prevent tar formation due to liquefaction of the vaporized gas due to the low nozzle temperature.

Further, in the case where the vaporizing portion formed between the burner mounting portion and the nozzle mounting portion is made linear and the two are communicated at the intersection of the vaporizing portion and the nozzle mounting portion, vaporization is achieved. It is easy to fill the part with a material for promoting vaporization, and the material and the like can be freely selected, and it is possible to improve tar performance as well as vaporization performance.

Further, the burner receiving seat integrally formed with the nozzle mounting portion and the opening for taking in the primary air is a nozzle mounted on the nozzle mounting portion by the conductive heat from the burner obtained from the burner mounting portion of the burner receiving seat. Since the temperature can be maintained relatively high, the primary air intake opening can be enlarged without worrying about the nozzle temperature drop, and the primary air intake opening can be increased without increasing the overall burner seat. Can be formed, and good combustion performance can be ensured while achieving compactness.

Further, in the case where the opening for taking in the primary air is formed by leaving the rib portion extending from the flat plate burner mounting portion to the nozzle mounting portion, not only on the vaporizing portion side but also on this rib portion side, The heat from the burner part placed on the burner placement part can be conducted to the nozzle via the rib part, and the temperature of the nozzle, which is easily cooled by primary air, is maintained at a temperature sufficient to prevent tar formation It is possible to maintain good tar performance throughout.
