Description

[Detailed Description of the Invention] The present invention relates to an improved structure of an oil combustor in which a combustion tube is removably mounted on a fire pan at the upper end of each of a core support tube and a core frame.

When igniting a combustion wick in such an oil combustor, as shown in FIG. The combustion wick 6 is ignited using a match or an ignition device.

However, when the combustion cylinder 1 is tilted too vigorously, it comes off the fire pan 5 and falls off, or when it is returned to the original fire pan 5 as shown by the solid line, the inner flame cylinder 1a and the middle flame cylinder 1b that constitute the combustion cylinder 1 are not in contact with each other.
The lower edge of the burner caught the upper end of the wick 6, so I had to try turning the burner tube 1 or lifting it up and down and redo it several times.

The present invention was devised in view of these points, and aims to eliminate the above-mentioned drawbacks and facilitate handling. In an oil combustor in which a wick is vertically movable and a combustion tube is removably mounted on the wick support tube and the fire pan at the upper end of the core frame, the combustion tube is provided in an inner flame tube constituting the combustion tube. A petroleum combustor in which a guide tube that opens vertically is attached to the center of the current plate, and the guide tube is loosely inserted into a guide hole provided in the center of the upper surface of the core support tube so that the combustion tube does not incline more than a certain angle. be.

Therefore, even if the combustion tube is tilted during ignition, the guide tube acts while regulating the combustion tube in the correct position, so even if the combustion tube falls off from the fire pan or returns to its original position, it will remain in the correct position. There is no need to pinch the combustion wick.

An embodiment of the present invention will be described below with reference to FIGS. 2 and 3. Reference numeral 7 denotes a core support tube that penetrates through the center of the oil tank, and has a guide hole 8 in the center of the upper surface and a plurality of passages around the periphery. A pore 9 is provided. Reference numeral 10 denotes a wick frame attached to the oil tank, and a combustion wick 11 is interposed in a gap provided between the wick frame and the wick support tube 7 so as to be vertically movable. The combustion wick 11 is moved up and down by a wick up-and-down mechanism, and during combustion it projects upward from a fire pan 12 provided at the upper end of the wick support tube 7 and the wick frame 10.

13 is a rod 14 that fixes the inner flame cylinder 13a of the punching plate, the middle flame cylinder 13b of the punching plate, and the outer cylinder 13c.
It is a combustion tube integrated by the inner flame tube 13
The lower edges of a and 13b are removably placed on the fire pan 12. The upper part of the outer cylinder 13c is the glass cylinder 1.
3'c is attached, and the upper end of the glass tube 13'c is supported by a fixed ring 15 attached by spot welding to the upper edge of the inner flame tube 13b.
The upper end opening of a is a cap 16 with a flame expansion plate 16'.
is fixed.

17 is a knob for lifting the combustion cylinder attached to the outer cylinder 13c via a metal fitting 18; 19 is a rectifying plate fixed horizontally to the lower part of the inside of the inner flame cylinder 13a; a plurality of air holes 20 are bored in the peripheral edge thereof; It is set up. 21 is attached by spot-welding the upper end flange piece 21' to the periphery of the central through-hole of the rectifier plate 19, and the lower end is a hollow guide tube with upper and lower end openings that extends downward from the lower end of the combustion tube 13 and contracts as it goes downward. It is loosely inserted into a guide hole 8 provided in the center of the core support cylinder 7.
The relationship between the guide tube 21 and the guide hole 8 is such that when the combustion tube 13 is tilted at a certain angle (approximately 20 degrees), the outer periphery of the guide tube 21 comes into contact with the periphery of the guide hole 8, and if the combustion tube 13 tilts further It is inserted loosely with a gap that prevents it from being inserted.

Therefore, when the knob 17 is turned to tilt the combustion tube 13 as shown in FIG.
It will not fall off. Also, when returning the combustion wick 11, the combustion wick 11 can be easily returned to the normal position without being pinched. Furthermore, since the guide tube 21 is open at the top and bottom, a draft effect occurs during combustion, thereby promoting the supply of combustion air into the inner flame tube 13a.
