Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a portable oil burner that gasifies and burns oil.

[Prior art and its disadvantages] A conventional portable oil burner has an oil tank built into the rear part of the burner cylinder, a gas nozzle arranged at the center of the tip of the burner cylinder, and a spiral shaped gas nozzle formed at the end of the gas nozzle. Incorporates a vaporizer,
This method heats and vaporizes oil led from an oil tank in a vaporizer, jets it out from a gas nozzle, and ignites it, but it has the following drawbacks.

Since an oil burner burns oil by vaporizing it, if the carburetor is not in a state where it can be vaporized at the time of startup, the oil will be ejected from the nozzle without being vaporized and will not be able to be ignited. Therefore, in the past, a separate heater was prepared to heat the vaporizer, and in many cases this heater was used to
It is heated for ~8 minutes to prepare for ignition, and it takes time to ignite, and the procedure is troublesome.

b. If oil spews out from the gas nozzle, it will scatter around and be dangerous.

c. In addition, conventional portable oil burners require a lighter to be ignited each time, making them difficult to operate.

[Object of the present invention] An object of the present invention is to enable automatic ignition and automatic heating of a vaporizer in a short time in a portable oil burner.

[Structure and operation of the present invention] The configuration of the present invention is as follows.

a Portable oil burner that incorporates a vaporizer into the tip of the burner cylinder, gasifies oil led from the oil tank, guides it to a nozzle, and blows out the gas from the nozzle to form a flame at the flame port. b) a preheating oil burner is installed near the vaporizer, and oil in the oil tank is supplied to the oil burner via the preheating oil tank; c) facing the oil burner; A gas burner for ignition was installed, and gas was supplied to the gas burner from the gas tank via the gas line; d) A preheating oil valve was installed in the preheating oil line by operating the main lever, and the main A portable oil burner comprising: a valve configured to be openable and closable; e; an ignition device facing the gas burner; and f.

When the oil burner is first used, the ignition lever is operated to open the gas valve, gas is ejected from the gas burner, and the gas burner is ignited by, for example, piezoelectric discharge. Next, the main lever is operated to eject oil from the oil burner, and the oil burner is ignited by the flame of the gas burner.

When the oil burner finishes igniting, the gas valve closes and the gas burner goes out, and the oil burner heats the vaporizer.

The heating state of the vaporizer is detected by a temperature sensor, etc., and after confirming that the vaporization is possible, the main valve is opened and oil is supplied from the oil tank into the vaporizer. The supplied oil is gasified by the vaporizer, and this gas is ejected from the gas nozzle, mixed with primary air in the flame tube inside the burner cylinder, and forms the tip of the flame tube while drawing in secondary air. .

Note that the oil burner goes out when a flame is formed in the flame tube.

The oil burner is ignited in this way and continues to burn, and is extinguished by closing the main lever and closing the main valve.

In the present invention, the piezoelectric ignition method is practical for the ignition device, but other methods may also be used.

At the time of startup, the vaporizer must be heated to a state where it can completely vaporize. For this purpose, it is desirable to attach a safety device to the vaporizer, such as a bimetal or liquid crystal type temperature sensor, and to control the opening and closing of the main valve by checking the safety of this safety device.

[Example and its operation] 1 is a metal burner cylinder, and this burner cylinder 1
An oil tank 2 and a manual pressurization pump 3 are built into the rear interior. 4 is a handle of the pump 3, and 5 is a valve of the pump 3.

Reference numeral 6 denotes a carburetor built into the tip of the burner cylinder 1. This carburetor 6 consists of a tube rolled up in a spiral shape, the tip 6' is connected to the gas nozzle 7, and the rear end 6'' is connected to the main gas nozzle 7. It is connected to the oil tank 2 via an oil line 9 via a valve 8 .

A preheating oil burner 10 is installed near the carburetor 6, and oil is supplied from the oil tank 2 via a preheating oil line 11.

12 is a gas burner, and this gas burner 12
is installed facing the oil burner 10, and gas is supplied from a gas cylinder 13 via a gas line 14.

15 is a main lever, and when this main lever 15 is turned 45 degrees clockwise in FIG. 1, the preheating oil valve 1 attached to the preheating oil line 11
6 is opened, and when turned 90 degrees counterclockwise from this position, the main valve 8 opens, and the preheating oil valve 16
closes.

17 is a piezoelectric generator, and this piezoelectric generator 17
The passive element 19 is struck by the striker 20 of the ignition lever 18, which rotates clockwise in FIG. 21.

Simultaneously with the high voltage generation operation, the ignition lever 18 opens the gas valve 22 attached to the gas line 14 between the gas cylinder 13 and the gas burner 12, allowing gas to flow from the gas outlet 10' of the gas cylinder 13 through the gas inlet 23. is supplied to the gas burner 12. In Fig. 5, 25 is the gas filling port, 26 is the blocking plug, and 27 is the oil tank 2.
28 is a filtration membrane, and 29 is a filtration membrane mounting bolt.

Next, the operation of the above embodiment will be explained.

●When igniting When the ignition lever 18 is pushed in, the striker 20 strikes the passive element 19 of the piezoelectric generator 17 and discharges to the electrode 21. At the same time, the gas valve 22 is opened and the gas in the gas cylinder 10 is passed through the gas line 14. is supplied to the gas burner 12. As a result, the gas burner 12 is ignited.

Next, when the main lever 15 is turned 45 degrees clockwise in FIG. 1, the preheating oil valve 16 in the preheating oil line 11 opens, and the oil tank 2
Oil is supplied to the oil burner 10 from inside. As a result, the flame of the gas burner 12 is transferred to the oil burner 10, and a flame is formed in the oil burner 10. This flame is vaporizer 6
heat up. When the ignition lever 18 is released, the gas valve 22 closes and the flame of the gas burner 12 is extinguished.

After confirming that the carburetor 6 has been heated sufficiently to gasify the oil, turn the main lever 15.
When you turn 90 degrees counterclockwise, first the main valve 8
opens and the oil in the oil tank 2 flows into the vaporizer 6.
Supplied. This supplied oil is transferred to the vaporizer 6
The gas is gasified at the gas nozzle 7 and ejected from the gas nozzle 7. The ejected gas enters the flame tube 24 while taking in primary air, mixes and is ejected from the tip flame port of the flame tube 24, and is transferred to the oil burner 10 to form a main flame.

Note that when the main lever 15 is operated in the above-mentioned operation, the main valve 8 first opens, and after a short delay, the preheating oil valve 16 closes.

When the main flame is formed, the vaporizer 6 is heated by the main flame and continuously gasifies the oil to maintain the main flame.

●When extinguishing a fire, turn the main lever 15 clockwise 45 degrees (return it) to close the main valve 8, and the oil tank 2
The supply of oil from the to the carburetor 6 is stopped, and the main flame is extinguished.

[Effects of the present invention] As described above, the present invention incorporates an oil burner and a gas burner that ignites the oil burner in a burner cylinder, and first ignites the gas burner and uses this flame to ignite the oil burner. Since the vaporizer is heated by the flame of this oil burner, the following effects can be expected.

a Since the vaporizer is heated by the oil burner inside the burner cylinder, the vaporizer can be heated quickly.

b) The oil burner is ignited by a gas burner, and an automatic ignition method using piezoelectricity or the like is used to ignite the gas burner, so the ignition operation is simple and reliable.

c. Due to the effects of a and b above, there is no danger of oil directly spouting out during startup.
