DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a petroleum combustion apparatus such as a petroleum stove and, more particularly, to an improvement in a device for raising and lowering a combustion wick.

[0002]

2. Description of the Related Art Conventionally, in a wick elevating device of an oil burning apparatus, an elevating arm is connected to an operation lever, and the wick is moved vertically by the elevating arm. A conventional combustion wick 5 and wick holder 52 are shown in FIG.

In FIG. 9, a combustion wick 5 is formed in a cylindrical shape having a combustion portion 53 made of glass wool or the like on an upper portion. An opening 54 is formed in the center of the wick 5. On the other hand, the wick holder 52 having a cylindrical shape and having an engaging portion 55 formed at the center is housed in the combustion wick 5.
When the wick holder 52 is placed in the combustion wick 5, the engagement portion 5
5 project outward from the opening 54. This engagement part 5
A hole 56 is provided in 5, and the lifting arm 4 is engaged.
The vertical movement of the lifting arm 4 moves the combustion wick 5 in the vertical direction.

Conventionally, the combustion wick 5 is provided with a concave portion 57. As shown in FIG. 8, the conventional combustion wick 5 is raised to the uppermost end at the time of ignition and lowered to the combustion position at the time of combustion.

Considering the state during combustion, the concave portion 57
When ignition is performed without providing the heater, it is necessary to set the heater position to h, and this heater position h is higher than the upper end of the combustion wick 5 during combustion, and the heater is exposed to high temperatures during combustion. is there.

Therefore, the heater position h is set at the position of the combustion core 5 during combustion.
The above disadvantage was solved by setting the position H below the upper end, but in this case, the heater position H and the upper end of the combustion wick 5 must be opposed at the time of ignition in order to perform reliable ignition. Therefore, a concave portion 57 is provided for this purpose.

[0007] The reason why the combustion core 5 and the lifting arm are once raised to the uppermost end and then lowered to the combustion position is to set the anti-seismic device. The operating lever is also connected to the set mechanism of the anti-seismic device.When the operating lever is pushed down to the lowermost end and the pressing force is released, the operating pin of the anti-seismic device returns slightly upward and the engaging portion And the anti-seismic device is set. At this time, the elevating arm connected to the operation lever moves to the uppermost end, and when the pressing force is released, it lowers to the combustion position.

[0008]

When the recess 57 is formed in the combustion wick 5 as described above, the combustion state deteriorates, and the dimensional accuracy of the ignition heater 8 and the recess 57 becomes unstable and the ignition performance deteriorates. In addition, since the special processing of forming the concave portion 57 is required, there is an inconvenience that the cost of the combustion core 5 increases. If it is only necessary to ignite and burn in oil-fired equipment, it is not necessary to raise the combustion wick 5 to the top end and then lower it, but to set the vibration wick 5 Is raised and lowered, which causes a problem as described above.

An object of the present invention is to make the combustion wick 5 at the same position at the time of ignition and at the time of combustion, thereby making the combustion wick 5
It is an object of the present invention to provide an oil-fired apparatus which can eliminate the necessity of forming the concave portion 57 in the fuel cell, improve the combustion state, improve the ignition performance, and reduce the cost of the combustion wick 5.

[0010]

According to the present invention, there is provided a lift arm which is lifted up to the uppermost end and then descends to a predetermined position by releasing the lifting force, and a combustion core which moves up and down when the lift arm is engaged. In the oil-fired equipment provided with, the abutting portion of the elevating arm is provided on the flange of the core outer cylinder mounting part of the combustion tank to stop the ascent and to adjust the core adjustment shaft assembly to absorb the excessive operation when setting the operating part. A movable portion of a fine adjustment pin corresponding to an excessive operation at the time of setting is provided on a connecting plate connecting the operation portions, and further, an urging means for urging the adjustment pin of the operation portion upward in the movable portion is provided. Things.

[0011]

In the present invention, the lifting arm is engaged with the hole of the combustion wick, and when the lifting arm moves upward, the lifting arm first hits the contact portion of the combustion tank and stops lifting. Here, the tuning pin moves the movable portion of the connecting plate connecting the operating portion and the core adjusting shaft assembly while urging the return spring downward. At this time, the lifting arm is stopped at the contact portion of the combustion tank, so that the connecting plate, the core adjusting shaft, the combustion core, and the like are also stopped. That is, the combustion wick does not move beyond the combustion position.

When the lifting force is released, the adjusting pin attached to the operation lever moves the movable portion of the connecting plate upward and returns to the original position. At this time, since the adjustment pin is urged upward by the return spring, the lifting arm, the core adjustment shaft,
The connecting plate and the combustion wick remain stopped. Note that the distance that the tuning pin moves upward and downward is accommodated in the movable portion of the connecting plate.
