Description

Description: TECHNICAL FIELD The present invention relates to an oil combustor equipped with a core lifting mechanism, which is provided with a main mechanism operated on the front surface of the equipment body. Separately, the present invention relates to a front panel of an oil combustor provided with a normal fire extinguishing button that slowly descends and an emergency fire extinguishing button that steeply descends by operating a seismic activation means.

[Prior Art] An oil combustor that burns by moving up and down the wick is equipped with a mechanism for extinguishing an emergency by detecting vibration such as an earthquake according to JIS standards, and the normal operation is to turn the wick up and down knobs. It moves or moves up and down to drive the vertical axis of the core. Also,
In addition to the core upper and lower knobs, there is a thing with a fire extinguisher button attached to operate the seismic activation means arbitrarily to extinguish an emergency.
(Refer to Japanese Patent Publication No. 1-43212) Furthermore, an operating lever that rotates the vertical axis of the core is provided, the operating lever is driven up and down by the upper and lower knobs of the core, and a fire extinguishing knob is provided separately from the upper and lower knobs of the core. There is one that lowers the core by pushing down the fire extinguishing knob. (Refer to U.S.A. 59-96504) [Problems to be solved by the invention] A mechanism for extinguishing a fire by manually operating a seismic activation means is as follows.
It descends longer than the descent distance of the core due to normal fire extinguishing operation,
The descent speed is also designed to be lowered quickly, and when extinguishing the fire, it extinguishes almost immediately, so unburned gas rises into the combustion area after extinguishing and causes a foul odor.

For this reason, measures have been taken to reburn the unburned gas by using a catalyst as a device that absorbs the unburned gas during the fire extinguishing operation, or to force the unburned gas to escape to the outside of the combustion range by suctioning the motor. However, this is not a good solution because the catalyst has a durability problem, the motor suction does not work without the battery, and a new battery has to be replenished, which does not completely eliminate unburned gas.

Recent oil combustors are mainly operated to move the core up and down by operating the lever up and down, and since it is necessary to store operating force in the spring means for emergency fire extinguishing by this lever operation, in order to operate it lightly The operating distance becomes large. Therefore, when extinguishing the fire with the core upper and lower knobs, a large operating distance is required, and there are more cases of extinguishing with the emergency fire extinguishing button than with this core upper and lower knobs, and the foul odor during the fire extinguishing operation is quite terrible. It was

On the other hand, as a countermeasure against this, the pivoting of the operating lever in the direction of lowering the core moves a little because it is not related to the spring means.Therefore, a normal fire extinguishing button is attached to perform the core lowering operation by directly pushing down the operating lever. By pushing the operation lever to the normal fire extinguishing position with a small push-down operation, it is possible to extinguish one-touch fire with very little foul odor.

However, the emergency fire extinguishing button and the normal operation button are arranged close to each other on the operation part of the front panel, and since many parts are located in a narrow space, the assembly process is complicated, costly, and difficult to make. It was

[Means for Solving the Problem] The present invention relates to an easy-to-make core up / down operation device having a normal operation button and an emergency fire extinguishing button, and an operation lever 2 for rotating a core up / down shaft 1, and the operation lever 2. A drive for interlocking and vertically moving the core up-down knob 5 that moves up and down along the sliding hole 4 of the base plate 3 of the core up-down device, and the core up-down shaft 1 as the center of rotation for driving the operation lever 2 in the down-axis direction. A plate 12, a spring means 6 mounted between the base plate 3 of the core lifting device and the drive plate 12, and driving the operating lever 2 in the core descending direction via the drive plate 12, and stored by the spring means 6. And an emergency digestion button 10 for manually operating the seismic activation means 7 in cooperation with the seismic activation means 7, and a core upper and lower knob of the operation lever 2. Connected to the end on the opposite side of 5, and when pressing down, the core vertical axis In an oil combustor having a normal fire extinguisher button 9 that rotates in the direction of lowering the core, an operating portion 8 is formed on the front panel of the oil combustor, and the normal fire extinguishing button 9 is attached to the operating portion 8 so as to be vertically movable. Also, a coil spring 11 is mounted between the upper portion of the operation section 8 and the normal fire extinguishing button 9, while the emergency fire extinguishing button 10 is attached to the operation section 8 near the normal extinguishing button 9 so as to be horizontally movable,
A part of the emergency fire extinguishing button 10 is located between the coil spring 11 and the operation portion 8, and the emergency fire extinguishing button 10 is also returned by the coil spring 11 for returning the normal fire extinguishing button 9.

[Explanation of Operation] In the present invention having the above configuration, when the normal fire extinguishing button 9 is pushed down to extinguish a burning oil combustor, one end of the operating lever 2 is lowered while extending the coil spring 11, The operating lever 2 is normally rotated to a fire extinguishing position to enable extinguishing a fire with less foul odor. When the normal fire extinguishing button 9 is stopped from being pushed down, the coil spring 11 contracts, and the normal fire extinguishing button 9 is separated from the operation lever and returns to the old position.

On the other hand, the coil spring 11 is located along the operation portion 8,
When the emergency fire extinguisher button 10 is pressed while the oil combustor is burning, a part of the emergency fire extinguishing button 10 is located between the coil spring 11 and the operating portion 8, so the middle of the coil spring 11 is separated from the operating portion 8. Since the seismic-sensing starting means 7 is operated while moving in the direction, the spring means 6 drives the operating lever 2 to the instantaneous fire extinguishing position via the drive plate 12. Further, when the pushing operation of the emergency fire extinguishing button 10 is stopped, the coil spring 11 moved in the direction of separating from the operating portion 8 returns to the linear direction, and at this time, the emergency fire extinguishing button 10 also returns to the old position. It is a thing.
