Description

[Detailed Description of the Invention] <Technical Field> The present invention includes a vaporizer for vaporizing liquid fuel into vaporized gas, and a burner for burning the vaporized gas discharged from the nozzle of the vaporizer. The present invention relates to a liquid fuel vaporization type combustion device equipped with a liquid fuel vaporization type combustion device.

<Prior art> In a conventional Bunsen type combustion device, the positional relationship between the carburetor and the burner is such that the center of the nozzle and the center of the burner suction pipe are on a straight line, but the vaporization chamber is located below or below this straight line. It was located on the extension of this straight line A.

Figure 2 is a configuration diagram of the main parts of a conventional vaporization type combustion device such as an oil fan heater, when the vaporization chamber 2 of the vaporizer 1 is located below the straight line A connecting the nozzle 3 and the suction pipe 5 of the burner 4. It is. When this vaporizer 1 is used, the combustion flame on the burner 4 does not directly contact the vaporization chamber 2 of the vaporizer 1, making it difficult to recover the combustion heat during combustion, which tends to increase power consumption. Ta. In order to solve this problem, the vaporizer 1 was provided with a combustion heat recovery section 6, but since the volume increased by the self-heat recovery section 6, the vaporizer 1 became larger than necessary. This increases manufacturing costs and requires a longer preheating time.

In addition, since the downward suction of warm air has recently become mainstream in oil fan heaters, it is desirable to lower the position of the combustion part as much as possible, that is, the position of the straight line A connecting the nozzle 3 and the suction pipe 5 of the burner 4 from the stand. However, since the vaporization chamber 2 that fills the vaporization element 7 is located below the straight line A connecting the nozzle 3 and the suction pipe 5 of the burner 4, the combustion section can be lowered by the length of the vaporization chamber. Nakatsuta.

In addition, 8 in the figure is a heater for preheating the vaporizer 1, and 9 is a heater for preheating the vaporizer 1.
1 is a temperature sensing element that detects the temperature of the vaporizer 1; 10 is a cleaning rod driving solenoid that opens and closes the nozzle; 11 is a tank; 12 is an oil pump; 13 is an oil pipe;
14 is a return oil pipe, and 15 is a solenoid valve that opens and closes the return oil pipe 14.

Figure 3 shows the main part configuration of a conventional vaporization combustion device such as an oil fan heater in which the vaporization chamber 2 of the vaporizer 1 is located on the extension of the straight line A connecting the nozzle 3 and the suction pipe 5 of the burner 4. It is a diagram. In this fan heater as well, the vaporizing chamber 2 of the vaporizer 1 is connected to the straight line A connecting the suction pipe 5 of the burner 4 and the nozzle 3, as described above.
Therefore, in order to recover the combustion heat, it is necessary to provide the combustion heat recovery section 6 in the vaporizer 1, which increases the size of the vaporizer 1. Furthermore, although it is possible to lower the combustion section, the combustion section becomes longer, making it difficult to downsize the device.

<Purpose> In view of the above, an object of the present invention is to provide a liquid fuel vaporization type combustion device that is small in size, can reduce manufacturing costs, and can lower the position of the combustion section.

<Example> Hereinafter, an example of the present invention will be described mainly based on FIG. 1. The liquid fuel vaporization type combustion apparatus according to the present invention includes a vaporizer for vaporizing liquid fuel into vaporized gas. 18, and a burner 4 for burning the vaporized gas discharged from the nozzle of the vaporizer 18, the vaporization chamber 2 of the vaporizer 18 connects the nozzle 3 and the gas suction pipe 5 of the burner 4. It is placed above straight line A.

That is, the carburetor 18 is composed of a carburetor main body 19, a carburetor cap 20 to which an oil feed pipe 13 for supplying liquid fuel to the main body 19 is connected, and a nozzle 3 connected to the main body 19. The vaporizer main body 19 is composed of a vaporizing section 19A having a vaporizing chamber 2 filled with a vaporizing element 7, and a vaporized gas passage section 19B integrally formed in the lower part of the vaporizing section 19A. It consists of a vertical path 21a that sends the vaporized gas from the chamber 2 downward, and a horizontal path 21b that sends the vaporized gas horizontally from the vertical path 21a to the nozzle 3. The horizontal passage 21b is arranged on an extension of a straight line A connecting the center of the nozzle and the center of the suction pipe of the burner, and the vaporizing section 19A is arranged above the passage section 19B so as to be inclined toward the burner side. The carburetor cap 20 is then screwed onto the upper end of the main body 19. Further, the heater 8 and temperature sensing element 9 for preheating the vaporizing section 19A of the main body 19 are arranged on the side opposite to the burner of the vaporizing section 19A. The burner also includes a suction pipe 5 arranged horizontally facing the nozzle, a combustion pipe 4a arranged above the suction pipe 5 and having a flame hole (not shown), and a red-hot It consists of a body 4b.

The other configurations are the same as the configuration of the conventional example shown in FIG.

In the above configuration, when the combustion operation is started, the oil feed pump 12 and the solenoid valve 15 are energized, and the oil feed pump 12 is driven and the solenoid valve 15 is closed. Therefore, fuel from the oil feed pump 12 is supplied into the carburetor 18 via the oil feed pipe 13.
The vaporizer 18 is heated by the heater 8, and the fuel supplied into the vaporizer 18 is vaporized in the vaporization element 7 filled in the vaporization chamber 2, and then passed from the nozzle 3 to the burner 4.
is supplied to the suction pipe 5 of the burner 4, and the well-known combustion is carried out on the flame hole of the burner 4. At this time, the vaporizing section 1 of the vaporizer 18
Since 9A is located above the straight line A connecting the nozzle 3 and the suction pipe 5 of the burner 4 and is tilted toward the burner 4, the combustion flame comes into direct contact with the vaporization part 19A, and combustion heat is efficiently recovered. can. Therefore, less electricity is required to be supplied to the heater 8, and power consumption can be reduced.

In addition, since the vaporization section 19A directly recovers combustion heat, a conventional recovery section is no longer necessary, and the vaporization section 19A directly recovers combustion heat.
8 becomes smaller, making it possible to reduce manufacturing costs and shorten preheating time.

Furthermore, since the vaporization section 19A is located above the straight line A connecting the suction pipe 5 of the burner 4 and the nozzle 3, the position of the combustion section can be lowered by placing the tank 11 in a position where it does not interfere with the combustion section.

Note that when extinguishing a fire, it is the same as before; when a fire extinguishing switch (not shown) is closed, electricity is cut off to the oil pump 12, solenoid valve 15, and heater 8, and the supply of fuel to the carburetor 18 is interrupted. Since the solenoid valve 15 is opened at the same time as the carburetor 1 is stopped, the solenoid valve 15 is opened.
The fuel remaining in the burner 8 is returned to the fuel tank 11 via the return pipe 14, and combustion in the burner 4 is instantly stopped.

It should be noted that the present invention is not limited to the above embodiments, and it goes without saying that many modifications and changes can be made to the above embodiments within the scope of the present invention.

<Effects> As is clear from the above explanation, the present invention includes a vaporizer for vaporizing liquid fuel into vaporized gas;
a burner for burning vaporized gas discharged from a nozzle of the vaporizer; the vaporizer has a vaporizer main body; and a nozzle integrally connected to the vaporizer main body; The vaporizer main body includes a vaporizing section having a vaporizing chamber, and a vaporized gas passage section integrally formed in the lower part of the vaporizing section, and the vaporizing chamber is connected to the nozzle and the gas suction pipe of the burner. and the vaporizing section is arranged above the vaporizing gas passage section so as to be inclined toward the burner so that its upper end is located above the end of the burner. This invention relates to a fuel vaporization type combustion device.

Therefore, according to the present invention, since the vaporizer is placed to the side of the burner, the burner is not overheated by the radiant heat from the vaporizer, compared to a case where the vaporizer is simply placed above the burner. can be prevented, and can prevent adverse effects on combustion.

In addition, since the nozzle and the vaporizer body are integrated, the heat capacity is sufficiently large, and the vaporized gas is rarely cooled between the vaporization part and the nozzle.
Stable blue flame combustion can be obtained.

Furthermore, since the vaporization chamber is located above the straight line connecting the burner suction pipe and nozzle, the position of the combustion section can be lowered by placing the tank in a position where it does not interfere with the combustion section.

In addition, since the vaporization part is tilted toward the burner side,
The combustion flame comes into contact with the vaporization section, allowing efficient recovery of combustion heat, reducing power consumption, and eliminating the need for the conventional recovery section, making the vaporizer more compact, reducing manufacturing costs and preheating time. There are excellent effects if it becomes possible to shorten the time.
