生することになる。 Conventionally, this kind of liquid fuel combustion equipment such as oil,
The inner flame tube and the outer flame tube of the combustion tube are placed on the fire pan, and the wick is advanced between the inner flame tube and the outer flame tube, and the wick is supplied from the ventilation hole between the inner flame tube and the outer flame tube. The structure uses combustion air to burn the fuel impregnated in the wick. In such a structure, in order to reduce the firepower, the amount of protrusion of the wick into the fire pan can be reduced.
If the combustion position in the combustion tube is lowered and the temperature of the fire pan increases, and if combustion continues for a long time, a large amount of tar in the kerosene will adhere to the wick or the fire pan, causing insufficient combustion and causing the wick to rise and fall. This does not occur smoothly, and a large amount of carbon monoxide gas is generated in the exhaust gas compared to during strong combustion when the wick is raised to a predetermined position.

燃焼装置が開発されている。 For this purpose, an adjustment tube is provided in the inner flame tube of the combustion tube, and the adjustment tube is installed in this adjustment tube so that it can be raised and lowered.During weak combustion, this adjustment tube is lowered to adjust the protruding height of the wick from the fire pan. The combustion air is mainly guided and supplied from the upper side of the inner flame cylinder,
By weakening the draft to the combustion part, drastically reducing the amount of air supplied near the wick, and reducing the amount of combusted vaporized gas, a weak combustion state with a good balance between the amount of air and vaporized gas is maintained. Combustion equipment that can prevent tar adhesion and carbon monoxide gas generation has been developed.

A structure is adopted in which a screw 6 inserted through a screw insertion hole 5 formed in the lower surface of the adjustment tube 1 is tightened and screwed together, thereby tightly fixing the lower surface of the adjustment tube 1 and the upper end surface 3 of the adjustment rod 2. In this structure, the adjustment tube 1 is fitted into the inner flame tube of the combustion tube with a small gap that allows it to swing, and the adjustment rod 2 is supported in the center of the core guide inner tube so that it can move up and down. If the center of the combustion tube fitted into the fire pan deviates from the center of the wick guide inner cylinder, the adjustment tube 1 will not move up and down smoothly, and the combustion tube itself will be unstablely supported by the fire pan, causing the adjustment tube 1 It has the disadvantage that it cannot be raised or lowered.

The inner flame tube 30 and the outer flame tube 31 of the combustion tube 29 are raised.
The upper end of the wick 14 is made to protrude from the fire tray part 26 so as to face between the two. Then, the wick 14 is ignited and burned by an ignition device (not shown).

等に供給されて強燃焼となる。 For strong combustion, when the operating side of the adjustment lever 53 is pushed down, the adjustment rod 43 is pushed up, the adjustment cylinder 39 is raised inside the adjustment inner cylinder 35, and the lower end of the adjustment cylinder 39 is moved inside the adjustment cylinder. The center opening 2 of the core guide cap 25 is approximately at the same height as the lower end of the tube 35.
A gap is created between 7 and the lower end of the adjustment cylinder 39. The air sucked from the lower end suction portion 28 of the core guide inner cylinder 13 flows into the inner flame cylinder 30 from the opening of the core guide cap 25, and then flows into the inner flame cylinder 30 and the outer flame cylinder 30 through all the ventilation holes 34 of the inner flame cylinder 30. The flame is supplied almost evenly between the flame tube 31 and strong combustion occurs.

酸化炭素ガスの多量の発生がない。 In addition, for weak combustion, if the operating side of the adjustment lever 53 is pushed up while keeping the intensity constant without changing the protruding height of the lamp wick 14 from the fire pan 26, the adjustment rod 43 is pulled downward, and the adjustment tube 39 closes the opening 27 of the core guide cap 25, and almost no air flows between the outer surfaces of the adjustment tube 39 and the adjustment inner tube 35 and the inner surface of the inner flame tube 30, and combustion air flows from the lower part of the inner flame tube 30. The supply of air is suppressed, and the air supplied from the opening 27 of the core guide cap 25 passes through the ventilation hole 41 of the adjustment cylinder 39 and the ventilation hole 3 of the adjustment inner cylinder 35.
8 and is supplied to the upper part of the inner flame tube 30. For this reason, compared to during strong combustion, combustion air is mainly flowed in from a higher position in the inner flame cylinder 30, so the draft to the combustion part is weakened, and the amount of air supplied to the vicinity of the wick 14 is also drastically reduced, causing the combustion to vaporize. The amount of gas will also decrease. Therefore, even if the protrusion height of the lamp wick 14 is kept constant, a weak combustion state with a well-balanced amount of air and vaporized gas is achieved, and there is no adhesion of tar or generation of large amounts of carbon monoxide gas.

At position 9, the amount of elevation can be adjusted steplessly, and the amount of heat generated can be adjusted steplessly. The adjustment lever 53 is engaged with the stop pin 56 and the resistance hole 57 to hold the adjustment cylinder 39 at an arbitrary vertical position, so that the adjustment cylinder 39 is not lowered by its weight.

It can also be swingably connected to the rod 43. That is, a joint piece 60 is rotatably connected to a shaft support piece 59 protruding from the bottom surface 40 of the adjustment cylinder 39 by a first pin 61, and a second pin 60 is connected to the joint piece 60 in a direction orthogonal to the first pin 61.

る。 According to the present invention, in a liquid fuel combustion device, combustion air supplied from the inside of the core guide inner cylinder can be varied in strength or weakness, including the upper or lower part of the combustion cylinder, by vertical movement of the combustion cylinder. Since the adjustment cylinder is swingably connected to the adjustment rod that is supported in the center of the core guide inner cylinder so that it can be raised and lowered, it can be fitted into the adjustment inner cylinder in surface contact with a small gap that allows it to be raised and lowered. Even if the center of the adjustment cylinder and the position of the adjustment rod deviate, the adjustment cylinder can be raised and lowered smoothly, and the combustion cylinder is held stably in the fire pan and can be raised and lowered smoothly, making it possible to adjust the intensity of combustion. It will be carried out smoothly.
