And if a core up-and-down axis | shaft rotates in a core lowering direction during combustion, a core will move down and it will extinguish a fire.
[0003]
In recent years, the development of a combustion part that does not easily cause incomplete combustion even when the amount of combustion is reduced has progressed, and it has become possible to change to a preferred amount of combustion by adjusting the height of the lead. For this reason, when the temperature or heating power desired by the user during combustion is reached, the heating power can be adjusted within the adjustment range of the combustion amount by operating the vertical axis of the core.
[0004]
[Problems to be solved by the invention]
Although the combustion amount adjustment range is displayed for those that can adjust the combustion amount in this way, the driving distance of the lead in the adjustment range is very short, so it matches the combustion state where the maximum calorific value is reduced. It is difficult to adjust the combustion amount manually, and abnormal combustion may occur.
[0005]
In addition, there is a case where the combustion part disposed above the lead cylinder that holds the lead so as to move up and down can be replaced with one having a different maximum combustion amount. It is very difficult to do and often leads to overcombustion due to excessive wicking.
[0006]

Turn to extinguish fire.
[0017]
On the other hand, the core up-and-down shaft 1 can move the core 7 up and down arbitrarily as the locking piece 1a moves away from the projection 3d when the rotating plate 3 and the stopper 5 are engaged. The amount of combustion can be adjusted by changing the lead height by operation.
[0018]
When adjusting the combustion amount, when the maximum heat generation amount of the combustion section 9 and the maximum core height coincide with each other, there is no fear of abnormal combustion as long as it is within the adjustment range of the combustion amount. However, when the combustion unit 9 having a different maximum heat generation amount is changed by changing the size of the room to be used, excessive combustion may occur if the maximum core height is too high for the maximum heat generation amount. . In order to prevent excessive combustion, it is necessary to match the maximum core height in accordance with the change in the maximum heat generation amount, but it is difficult to operate the core vertical shaft 1 to match the maximum heat generation amount and the maximum core height. In many cases, excessive combustion caused by raising the wick too much.
[0019]

When the rotation stopper 6 is in the open position, the first engagement portion 3c engages with the stopper 5 and the upper combustion position is maintained when the core vertical shaft 1 is rotated in the center raising direction. On the other hand, when the rotation stopper 6 is set to the set position, when the core vertical shaft 1 is rotated to the lower combustion position, the locking portion 2 hits the rotation stopper 6 and the rotation of the core vertical shaft 1 is stopped. The second engagement portion 3b of the moving plate 3 engages with the stopper 5 to maintain the lower combustion position.
[0021]
If the core height when the core vertical shaft 1 is held at the lower combustion position by the rotation stopper 6 is set in accordance with the decrease in the maximum calorific value when the combustion unit 9 is changed, the change of the combustion unit 9 Even when the maximum heat generation amount is reduced, the maximum core height and the maximum combustion amount coincide with each other, and combustion is performed without causing abnormal combustion.
[0022]
Moreover, if arranged so detent 6 of the set position is brought into contact with the locking piece 1a of the core vertical shaft 1, and a second engaging portion 3 b and the stopper 5 of the rotating plate 3 in the combustion location of the subordinate when the engaged, but the core vertical shaft 1 can be independently rotated with the core drop position away from the engaging portion 2, the rotation stopper 6 which is rotated to the set position of the core vertical shaft 1 Therefore, the combustion amount can be accurately adjusted even when the rotating plate 3 and the stopper 5 remain engaged.
[0023]
Further, in the embodiment of FIG. 3 showing the structure to be changed by the combustion section 9, 9a is an outer cylinder constituting the outer wall of the combustion section 9, 9b is an upper cylinder having an outer diameter larger than that of the outer cylinder 9a, and the upper cylinder 9b is It moves up and down around the outer cylinder 9a. 9c is an elongated hole arranged at a plurality of positions on the top plate of the outer cylinder 9a, 9d is an L-shaped piece provided at the bottom of the upper cylinder 9b, and the L-shaped piece 9d of the upper cylinder 9b is moved when the upper cylinder 9b is moved upward. If the upper cylinder 9b is inserted into the long hole 9c of the outer cylinder 9a and the upper cylinder 9b is rotated in the circumferential direction, the upper cylinder 9b is fixed above the outer cylinder 9a, so that the entire length of the outer cylinder 9a and upper cylinder 9b is expanded and contracted. be able to.
[0024]
For this reason, when the upper cylinder 9b is moved upward and the overall length of the outer cylinder 9a and the upper cylinder 9b is extended, the rising airflow of the combustion section 9 becomes stronger and the maximum heat generation amount increases, and the upper cylinder 9b is moved downward. Then, when the full length of the outer cylinder 9a and the upper cylinder 9b is shortened, the maximum calorific value is lowered, so that the maximum calorific value of the combustion section 9 can be changed.
[0025]
Reference numeral 12 denotes a drive lever that interlocks the rotation stopper 6 and the upper cylinder 9b. Reference numeral 6a denotes a support shaft of the rotation stopper 6.

[0026]
When the full length of the outer cylinder 9a and the upper cylinder 9b is extended, the rotation stopper 6 is in the open position, so that the core vertical shaft 1 can be rotated to the upper combustion position, and the entire length of the outer cylinder 9a and the upper cylinder 9b is increased. When retracted, the rotation stopper 6 rotates to the set position, and the rotation stopper 6 that rotates to the set position pushes the locking piece 1a of the core vertical axis 1 so that the core vertical axis 1 rotates to the lower combustion position. The core vertical shaft 1 is prevented from rotating to a higher combustion position by a rotation stopper 6.
[0027]
For this reason, it is not necessary for the user to adjust the combustion amount by the core vertical shaft 1 or the rotation stopper 6 in accordance with the change in the maximum heat generation amount of the combustion unit 9, and the core 7 according to the decrease in the maximum heat generation amount of the combustion unit 9. Is set, and the lead 7 is not accidentally raised too much, so there is no possibility of abnormal combustion and stable combustion can be performed. In addition, when the maximum heat generation amount of the combustion unit 9 is changed in accordance with the size of the room to be used, it can be used with an appropriate amount of combustion, and can be used comfortably by preventing the room from being overheated. When the total length of 9a and the upper cylinder 9b is shortened, the oil combustor increases stability, so that it may be used as a stove and the usability is improved.
[0028]
【The invention's effect】
In the present invention, when the rotation stopper 6 is in the release position, the first engagement portion 3c of the rotating plate 3 is engaged with the stopper 5 to maintain the upper combustion position, and when the rotation stopper 6 is in the movable position, the rotation is stopped. Since the second combustion portion 3b of the moving plate 3 is engaged with the stopper 5 and the lower combustion position is maintained, the maximum core height is maximized by operating the rotation stopper 6 in accordance with the change in the maximum combustion amount. The amount of combustion can be matched and there is no risk of abnormal combustion.
[0029]
Further, since the engaging portion 3 a and the stopper 5 and is still the core vertical axis 1 of engagement of the rotary plate 3 is rotated, it becomes possible to finely adjust the combustion rate, the detent 6 to the movable position At the position where the rotation of the rotation plate 3 is stopped, the second engaging portion 3b of the rotation plate 3 and the stopper 5 are engaged, and the core vertical shaft 1 is rotated toward the lower combustion position. Even if it is moved, the rotation to the upper combustion position is stopped , so even if the combustion section 9 is changed, abnormal combustion does not occur.
[0030]
Furthermore, when the combustion unit 9 changes and the maximum heat generation amount changes, it is necessary to adjust the combustion amount by the core vertical shaft 1 and the rotation stopper 6 in accordance with the maximum heat generation amount of the combustion unit 9. The outer wall is composed of the outer cylinder 9a and the upper cylinder 9b, and when the upper cylinder 9b is moved downward to reduce the maximum heat generation amount, the upper cylinder 9b and the anti-rotation 6 are linked with the upper cylinder 9b. Since the rotation to the combustion position is stopped, the rising position of the wick 7 is set in accordance with the change in the maximum calorific value of the combustion section 9, and there is no possibility of causing abnormal combustion so that stable combustion can be performed. became.
