JPS60117006A - Wick elevating device for kerosene burner - Google Patents

Abstract

PURPOSE:To prevent the occurrence of abnormal combustion due to excess lowering of a wick, by a method wherein an engaging relation between a moving lever, mounted to a wick elevating knob, and a locking body, secured opposite to the moving lever, is set so that they are, at a minimum combustion amount wick position, engaged with each other only when the wick is lowered, and they are separated from each other during control of a lever driving knob. CONSTITUTION:With a wick elevating knob 2 turned in the direction in which a wick is raised, the wick 3 can be lifted up to a maximum height without engagement of a locking body 6 with a moving lever 4. Combustion is started through ignition of the forward end of the wick 3 lifted upward. With the wick elevating knob 2 reversed, the wick 3 lifted upward is lowered to decrease a combustion amount. In which case, the wick 3 is lowered until the moving lever 4 is engaged with a locking body 6. Such engaging position is set to a minimum combustion amount wick height position. This enables normal combustion to be kept within a range in which they are engaged with each other. Meanwhile, with the wick elevating knob 2 reversed as a lever driving knob 5 is controlled, the moving lever 4 is moved to a position where it is prevented from engagement with a locking body 6, and thereby the wick 3 can be lowered to a fireextinguishing position.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a wick up/down device related to changing the combustion amount of an oil combustor.

The amount of combustion in an oil combustor that uses a conventional combustion tube is only in one place that is suitable for the combustion tube, and the combustion ■ has been changed (change in wick height).
This caused problems such as incomplete combustion and foul odors.

However, recently, combustion tubes have been improved, and the JIS standard for kerosene stoves has improved.
2000 in terms of combustion exhaust gas standards that pass the standards.
For the maximum combustion amount of kaIA, 100 &aj/b~
Types with a variable internal combustion rate of 700 KcαI/h have been put into practical use, but some people are overconfident in the combustion rate and use it by lowering the combustion rate (core height) below the capacity. A situation arose.

To explain this invention which improves the above-mentioned problems with the drawings, l is the lead vertical axis, 2 is the lead'-lower knob, 3 is the lead that moves up and down by the lead up and down knob, and the pinion gear 9 at the tip of the lead up and down axis l. and a gear 11 connected to the lead holding cylinder 10 to which the lead 3 is attached are combined to move the lead 3 up and down when the lead up and down shaft rotates once. 4 is a movable lever attached to the core up and down knob 2; 5 is a drive knob of the movable lever; by operating the lever drive knob 5, the movable lever 4 is moved left and right or up and down; When the knob 5 is in a free state, it is held in either state by the action of the internal spring 12. Further, reference numeral 6 denotes a locking body fixed opposite to the core upper and lower knobs 2, and set in a locking relationship with the movable lever 4.

The locking relationship between the movable lever 4 and the locking body 6 is such that the lever drive knob 5 engages at the minimum combustion core height position only when the lever is temporarily lowered. During operation, the movable lever ~4 can be moved to a position where it does not engage with the locking body 6,
The wick 3 can be lowered to the extinguishing position.

In the figure, 7 is a core lowering rotation spring wound around the core vertical axis I, and 8
is a stopper ■3 that stops the accumulated force of the rolled-up core lowering rotation spring 7.
The locking body 6 is integrally connected to the locking gear 8 so that the stopper 13
The present invention can also be combined with an automatic fire extinguishing system that automatically lowers the wick when the wick comes off.

In use, this invention having the above-mentioned structure is capable of lifting the lead 3 to the maximum height without engaging the locking body 6 and the movable lever 4 when the lead upper and lower knobs 2 are rotated in the lead raising direction. Can be done. At this time, in the case of a device with a breath lowering automatic fire extinguishing device, the core lowering rotation spring 7 is wound up, and the locking gear 8 is connected to the stopper 1.
3 to hold the spring 7 in a wound state.

Then, by igniting the tip of the pulled-up wick 3, combustion in the oil combustor is started.

By the way, when the lead upper and lower knobs 2 are reversed, the lead 3 is pulled up.
However, in this invention, the wick 3 can be lowered until the movable lever 4 attached to the wick upper and lower knobs 2 engages with the locking body 6, and this locking position can be lowered. Since the minimum combustion amount was set at the wick height position, normal combustion could be maintained within the engagement range.

- When extinguishing an oil combustor, when the wick upper and lower knobs 2 are reversed while operating the lever drive knob 5, the movable lever 4 has moved to a position where it does not engage with the locking body 6, so the minimum combustion amount wick height In this position, the movable lever 4 and the locking body 6 did not engage with each other, and the wick 3 could be pulled down to the extinguishing position.

f^1 When the automatic fire extinguishing system is activated during normal combustion, if the locking body 6 is attached to the locking gear 8, the rotation spring 7
By the core vertical axis 1 (core vertical knob 2, movable lever 4)
When the locking body 6 rotates, the locking body 6 also rotates, so the rotation of the core vertical axis l is not stopped by the locking body 6.
It became possible to apply this invention to oil combustors with automatic fire extinguishing devices.

As mentioned above, with this invention, the combustion amount is always regulated to the amount that will cause normal combustion when the normal rotation of the upper and lower wick knobs is performed, so the operator will not accidentally lower the wick 3 too much and cause abnormal combustion, and the practical performance will be improved. has been improved.
