Description

[Detailed Description of the Invention] <Technical Field> The present invention relates to a stove such as a kerosene stove with a lifting wick, and particularly relates to calorie regulation.

<Prior art> Fig. 6 shows a conventional kerosene stove with an upper and lower core. In the figure, 1 is an oil tank, and a guide tube 2 and an outer core tube 3 concentrically protrude upward from the center of the tank 1. A core 4 is interposed between both cylinders 2 and 3 to form a guide cylinder 2.
It is fitted so that it can be raised and lowered freely. A burner 6 was fixed to the upper part of the guide tube 2 and the outer core tube 3. A core lifting mechanism is provided in the tank 1 to raise and lower the core 4, and the core 4 is moved up and down by changing the exposed dimension of the core 4.
The calorie content was controlled by adjusting the amount of oil gas vaporized from the tip.

However, the burner 6 has a core guide tube 2 and a core outer tube 3.
, the relationship between the capacity of the burner 6 and the exposed length of the wick 4 is only adapted to a small extent. That is, the capacity of the burner 6 is set so that completely stable combustion can be maintained at maximum wick exposure. For this reason, calorie adjustment is usually 20 to 30%.
is the limit, and if it is made smaller than that, burner 6
combustion tends to slow down and result in incomplete combustion. This is because the balance between the capacity of the burner 6 and the amount of oil evaporation is lost.

<Purpose> In view of the above, the present invention, in conjunction with the lifting and lowering of the core,
The objective is to provide a stove that allows a wide range of calorie adjustment by changing the effective length of the burner and setting the burner capacity commensurate with the exposed length of the wick.

<Example> Hereinafter, an example of the present invention will be described based on FIGS. 1 to 5. The stove according to the present invention has the following features:
a liquid fuel combustion wick 12 that is fitted onto the wick guide tube 11 so as to be able to rise and fall; a burner 13 that is disposed above the guide tube 11 and moves up and down in conjunction with the rise and fall of the wick 12;
The burner is provided with interlocking means 14 for interlocking the burner with the lifting and lowering of the wick 12.

The lower end of the guide tube 11 is fixed to the bottom surface 15a of the tank 15, and consists of a lower large diameter portion 11A and an upper small diameter portion 11B with a smaller diameter, and the length T of the small diameter portion 11B is the same as the core. It is set larger than the lifting width of No. 12. Further, an outer core cylinder 16 is fitted onto the outer periphery of the guide cylinder 11 and fixed to the tank 15, and an outer flange 17 is formed at the upper end of the core outer cylinder 16.

The core 12 also includes a suction part 12a that contacts the bottom surface 15a of the tank 15, a guide tube 11, and a core outer tube 1.
6 and a heat-resistant part 12b made of glass fiber that can be exposed above the guide cylinder 11. Further, the burner 13 is connected to the upper end surface through hole 1 of the guide tube 11.
A through hole 19 for allowing air flowing in from 8 to flow outside.
Consisting of an inner flame tube 20, an outer flame tube 22 with a through hole 21 fitted and fixed concentrically to the outer periphery of the inner flame tube 20, and an outer tube 23 externally fitted and fixed to the outer flame tube 22. has been done. As shown in FIGS. 1 to 4, the inner diameter A of the outer cylinder 23 is equal to the flange 1 of the core outer cylinder 16.
It is set larger than the outer diameter B of 7, and the outer flame tube 22
The outer diameter C of the core outer cylinder 16 is smaller than the inner diameter D of the inner flame cylinder 20, and the inner diameter E of the inner flame cylinder 20 is smaller than the small diameter part 11B of the guide cylinder 11.
It is set to be larger than the diameter F of the large diameter portion 11A and smaller than the diameter G of the large diameter portion 11A.

The interlocking means 14 includes an inner core holder 25 that is fixed to the inner surface of the core 12 and supports the inner flame tube 20 with an upper inner flange 24, and an inner core holder 25 that is fixed to the outer surface of the core 12 and supports the outer flame tube 20 with an upper outer flange 26. and an extra-core holder 27 that supports the. And the upper end inner flange 24 of the inner core holder 25
is slidably projected from the inner surface of the core along the small diameter portion 11B of the guide tube 11. That is, the upper inner flange 2
4 is made to be the same size as the diameter F of the small diameter portion 11B of the guide tube 11. Further, the upper outer flange 26 of the outer core holder 27 is slidably protruded from the outer surface of the core 12 along the inner surface of the outer core cylinder 16 . That is, the outer diameter of the upper outer flange 26 is the same as the inner diameter D of the core outer cylinder 16. Further, the inner diameter of the inner core holder 25 is set to be the same as the diameter G of the large diameter portion 11A of the guide tube 11.

In addition, the inner core holder 25 and the outer core holder 2
The horizontal portions 24a, 26a of the inner and outer flanges 24, 26 at the upper end of the core 12 are arranged to be located below the upper end 12c of the core 12 by an arbitrary height H (approximately 10 mm). In addition, the core 1 and both holders 25,
The assembly No. 27 can be raised and lowered from outside the tank 15.

In the above configuration, in order to achieve a low calorie state, the core 12 is lowered as shown in FIG. Then,
The burner 1 is supported by inner and outer flanges 24 and 26 at the upper ends of the inner-core holder 25 and the outer-core holder 27.
3 also lowers in conjunction with the lowering of the core 12. Therefore,
The effective length of the burner 13 is shortened, the shape and dimensions are commensurate with the exposed length of the wick 12, and complete combustion can be achieved.

Further, in order to achieve a high calorie state, as shown in FIG. 2, the core 12 is raised to maximize the exposed length of the core 12. Then, the effective length of the burner 13 supported by the inner core holder 25 and the outer core holder 27 is
It becomes large in conjunction with the rise in 2.

Note that the air for combustion at this time is supplied from between the outer cylinder 23 and the outer core cylinder 16 of the burner, and is also supplied from the inner core cylinder through the guide cylinder 11. However, when the wick 12 is lowered, the air supplied from the inner wick holder 25 and the outer wick holder 27 of the burner 13 becomes difficult to be supplied to the wick 12, the amount of oil vapor decreases, and the calorie is reduced.

In this way, a wide range of calorie changes can be obtained by selecting the through holes 19, 21 of the inner core holder 25 and the outer core holder 27, the diameter of the burner 13, the overall length of the burner 13, and the exposed length of the core.

<Effects> As is clear from the above description, the present invention includes a core guide tube having a through hole in the upper end surface, a liquid fuel combustion wick fitted onto the core guide tube so as to be able to rise and fall freely, and an upper part of the guide tube. The burner is provided with a burner that moves up and down in conjunction with the up-and-down movement of the core, and interlocking means for interlocking the burner with up-and-down movement of the core, and the burner is equipped with an air inflow from a through hole in the upper end surface of the guide tube. an inner flame tube with a through hole for flowing the water to the outside, an outer flame tube with a through hole that is externally fitted and fixed concentrically to the outer periphery of the inner flame tube, and an outer flame tube that is externally fitted and fixed to the outer flame tube. The inner diameter of the outer tube is set larger than the outer diameter of the core outer tube, the outer diameter of the outer flame tube is set smaller than the inner diameter of the core outer tube, and the inner diameter of the inner flame tube is set to be smaller than the inner diameter of the core outer tube. is set larger than the diameter of the guide tube,
The interlocking means includes an inner holder fixed to the inner surface of the wick and supporting the inner flame tube with an inner flange at the upper end, and an outer holder fixed to the outer surface of the wick and supporting the outer flame tube at the outer flange at the upper end. The inner flange at the upper end of the inner holder protrudes from the inner surface of the core so as to be able to slide vertically along the guide tube, and the outer flange at the upper end of the outer holder protrudes vertically along the inner surface of the outer tube. The present invention relates to a stove characterized in that the core protrudes from the outer surface side so as to be slidable in the direction.
