DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a Bunsen-type combustion apparatus for vaporizing a liquid fuel and ejecting the vaporized gas from a nozzle for combustion.

[0002]

2. Description of the Related Art Various types of combustion apparatuses of this type have been proposed. FIG. 4 shows an example, but this type is configured so as to save power. To explain the configuration, an electromagnetic pump 52 is mounted on the upper surface of an oil receiving tray 51, and one end of an oil feed pipe 53 is connected to the electromagnetic pump 52. The other end of the oil supply pipe 53 is connected to a circular evaporator 54, and the oil sent from the oil pan 51 by the electromagnetic pump 52 is supplied to the evaporator 54 and the evaporator lid 54.
A is sent to the vaporization chamber 55 constituted by A.

The vaporization chamber 55 has a slot 5 at the center of the vaporization chamber.
6 is formed so as to surround the heater 57.
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 supply pipe 53 of the vaporization chamber 55.

[0004] 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. Electromagnetic solenoid 6
The side opposite to the return pipe 60 is communicated with the oil pan 51, and the electromagnetic solenoid 61 is provided with a needle 62 for opening and closing the nozzle hole 63 of the nozzle 58.

[0005] A burner 66 is provided in close contact with an upper portion of the vaporizer lid 54A provided so as to cover the outlet 65 of the throat 56, and vaporized by a flame 67 formed on the peripheral wall of the burner 66. The flange 68 on the upper part of the vessel 54 is configured to be heated.

In the above configuration, the vaporization chamber 55 is provided with the heater 5
The oil is heated to a predetermined temperature by 7, and is vaporized in the process of reaching the communication passage 59 from the oil supply pipe inlet. The vaporized gas flows downward through the communication passage 59 at the lower part of the vaporization chamber and reaches the nozzle 58.

Here, when the vaporizer 54 reaches a predetermined temperature, the needle 62 opens, and the vaporized gas flows into the nozzle hole 63.
Squirts more. The vaporized gas flows vigorously toward a slot 56 provided in the center of the vaporizer, and accordingly, primary air is drawn in from between the slot lower end 69 and the nozzle 58, and the burner section 66 from the slot outlet 65. Inside, the mixture is ignited at the outer periphery of the burner section 66 to generate a combustion flame 67 and perform combustion.

On the other hand, the vaporizer 54 has an upper flange 68
Is heated by the combustion flame 67 and the burner 6
The vaporizer lid 54A is heated by the heat conduction from 6,
Due to the heat recovery action, vaporization is continued without energizing the heater 57, and combustion is continued, that is, self-combustion is performed, thereby saving power.

[0009]

However, the above conventional configuration has the following problems. That is,
Since the vaporizer 54 is formed around the outer periphery of the gas 56 so as to surround it, the vaporizer 54 itself becomes large,
It is difficult to reduce the size of the carburetor 4 and the manufacturing cost is high. In addition, the heat capacity of the carburetor 54 is increased 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 longer. There was a problem that.

Further, it is difficult to ensure the hermeticity of the vaporizer 54. Therefore, when the vaporizer 54 is actually to be commercialized, the vaporizer 54 is formed by joining a plurality of pipes and inserting the pipe into a slot. Complicated processing such as casting and forming integrally with 56 is required, and if a pipe is not cast, a vaporizer lid 54A must be covered on the vaporizer 54 and a sealant must be applied between them. In addition, there has been a problem that the manufacturing cost is increased and air-tight leakage and deformation due to variations in mass production occur, making it difficult to secure sufficient quality.

Further, the vaporizer 5 surrounding the slot 56
In the case of No. 4, since the shape is circular, it becomes difficult to fill a vaporizing element into the vaporizing chamber for smooth vaporization of oil and to suppress the generation of tar, for example, the selection of the vaporizing element is limited, and the tar property is limited. However, there is a problem that the performance cannot be sufficiently improved.

On the other hand, in the above-mentioned conventional configuration, since the nozzle 58 goes around and separates from the lower surface of the vaporizer 54, the vaporizer 54 and the nozzle 58 have a shape that is largely thermally separated from each other. As the temperature of the gas decreases and the nozzle 58 is located below the vaporization chamber 55, the vaporized gas that has become high temperature remains in the upper part of the vaporization chamber 55, and the low-temperature non-vaporized gas or oil passes through the lower communication path. There is a problem that the gas flows into the nozzle 58 through the nozzle 59, and the vaporized gas is difficult to flow, and the vaporized gas is easily turned from the communication passage 59 to the nozzle 58 due to the low temperature gas or the low temperature of the nozzle 58. Was.

For this reason, even if an attempt is made to fill the vaporizing chamber 55 or the communication path 59 from the vaporizing chamber 55 to the nozzle 58 with a vaporizing element for promoting vaporization, the vaporizer 5 surrounding the slot 56 is used.
4 is a circular shape, it is difficult to fill such a vaporizing element into the vaporizing chamber, and there is a problem that the selection of the vaporizing element is limited and the performance such as tar property cannot be sufficiently improved. Was.

Further, in the above-mentioned conventional configuration, the primary air suction amount can be increased as the nozzle 58 is separated from the vaporizer 54, but the position of the nozzle 58 cannot be lowered too much due to the tarring problem. There is also a problem that the air intake area determined by the positional relationship between the nozzle 58 and the inlet of the slot 56 cannot be increased, so that sufficient primary air for combustion cannot be obtained and the combustion performance of the burner is restricted. . In addition, since the slot 56 and the vaporizer 54 are integrally formed, the lower shape of the slot 56 is limited to a straight shape due to molding restrictions and the like, and the amount of primary air greatly affected by the throat shape is increased. There has been a problem that it is not possible to sufficiently take measures and noise reduction measures.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and has as its first object to shorten the ignition time while taking advantage of the power saving by heat recovery, and to reduce the cost by facilitating the processing and making it compact. The third object is to suppress the tarification of the vaporized gas as a third object.

In the above configuration, the oil delivered by the electromagnetic pump 2 enters the vaporization chamber 6 via the oil supply pipe 3.
The heater 15 heats the vaporizing section 4 until it reaches a predetermined temperature,
The oil in the vaporization chamber 6 is vaporized. The vaporized oil moves linearly toward the nozzle 8 and reaches the nozzle 8 via the communication path 7.

Can be retained. The rib portion 16 conducts the heat from the burner portion 19 to the vaporizing portion 4 as well as the nozzle mounting portion 8A, so that the temperature of the vaporizing portion 4 is maintained at a high temperature and at the same time. If a temperature sensor is attached to the rib portion 16, not only space can be saved, but also the temperature near the nozzle can be measured accurately.
