Abstract

PURPOSE:To reduce production of odor during ordinary fire extinguishing, by a method wherein, when a vibation fire extinguishing device is operated, fire is extinguished for a short time, and during ordinary fire extinguishing, a time in which fire is extinguished is lengthened. CONSTITUTION:In order to further lower a wick 32 for fire extinguishing, a rotation force higher than an ordinary rotation force is applied through operation of a knob 42. This causes a stopper 39e of a rotary body 39 to be axially moved by press caused by an actuating body 41, resulting in free rotation of the knob 42, and the actuating body 41 is rotated until the actuating body is engaged with a bent part 39d of a lock body 39b. The current (c) of the top of a wick is set to a position allowing fire to be extinguished within a time which is considered to ensure safety if, in a kerosene burner, ordinary fire extinguishing is preformed within said tine. This causes lengthening of a fire extinguishing time, enables continuance of combustion of kerosene vapor continued to be vaporized from the upper part of the wick through preheating, and permits sharp reduction in production of odor.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to an oil combustor that is used by moving the wick up and down.

Conventional structure and problems Generally speaking, this type of combustion appliance extinguishes the fire by lowering the wick, but normally this lowering of the wick is done by rotating the vertical axis of the wick (hereinafter referred to as manual extinguishing). However, in recent years, manual extinguishing means have been installed in conjunction with vibrating fire extinguishing devices that sense vibrations and lower the wick rapidly, and with one touch operation of this manual extinguishing means, the wick is lowered rapidly to extinguish the fire.

Extinguishing the fire using the manual fire extinguishing means can be performed with a one-touch operation, so it is easy to use and does not require the inconvenience of rotating the vertical axis of the wick, but it has the problem of a strong odor. As the wick descends rapidly and deeply (with a long descending stroke) to instantly extinguish the fire, oil vapor continues to be generated in the hot wick housing cylinder, which flows into the still hot combustion cylinder and heats up. This is because it decomposes and becomes the source of odors such as acetaldehyde. In particular, this manual fire extinguishing means is linked to a vibration fire extinguishing system that is stipulated to extinguish the fire within 10 seconds, so when extinguishing a fire using manual extinguishing means, it is always possible to extinguish the fire within a short time of 10 seconds. Although it is a normal fire extinguishing method that does not require extinguishing within 10 seconds, the fire extinguishes in the same short time as when a vibrating fire extinguisher is activated, emitting a strong odor and causing discomfort to the user. There was a problem.

Purpose of the Invention The present invention has been made in view of the above points.
f'/4*''W''4''f! lJEI
fffmlRiiJ Tm Light Co., Ltd. ZFtjK#- The purpose is to reduce the odor during normal extinguishing by increasing the time until extinguishing during normal extinguishing using a rotating and manual extinguishing means.

Structure of the Invention In order to achieve the above-mentioned object, the present invention provides a first stopping mechanism that stops the downward rotation of the lamp wick vertical shaft at a point closer to the lowermost rotational position of the lamp wick vertical shaft, which is rapidly lowered by the operation of a vibration extinguishing device. and a second stopping mechanism that stops the lamp vertical shaft, which rapidly rotates in the wick downward direction when the manual extinguishing body is operated, at a position closer to the lowest rotational position of the lamp vertical shaft, which rapidly descends when the vibration extinguishing device releases the lock. and is constructed so that the descending stroke of the lamp wick lowered by the hand crank and the manual extinguishing body is shorter than the descending stroke Q of the lamp wick lowered by the operation of the vibration extinguishing device.

DESCRIPTION OF EMBODIMENTS One embodiment will be described below with reference to the drawings. Figures 1 to 4
In the figure, 30 is a tank, 31 is a burner section installed in the tank, and 32 is a wick attached to the burner section 31 via a wick holder 33, which can be moved up and down between it and the wick guide tube 31a. Reference numeral 34 denotes a wick vertical shaft, which has a pinion 34a at its tip, and this pinion 34a is engaged with a rack 35 provided on the wick holder 33 in order to move the wick 32 up and down. Reference numeral 36 denotes a bearing for supporting the upper and lower shafts of the lamp wick, which is fixed to the tank 30, and 37 is a bearing fitting that supports the lamp upper and lower shaft packings 38, etc., which are fixed to the tank 30. Reference numeral 39 denotes a rotary body having a plurality of engaging portions 39a on its periphery, which is rotatably fitted into the lamp wick vertical shaft 34, and is made of polyacecool resin or the like. In this embodiment, this rotating body 39 has a bent portion 39c.

A locking body 39b having a diameter of 39d and a stop body 39e are provided by integral molding. Of the plurality of engaging portions 39a of the rotary body 39, -39a' is made taller. Reference numeral 40 denotes a fire extinguishing spring for lowering the lamp wick, which is fitted around the rotating body 39, and is pre-wound in advance, and one end is attached to the bearing fitting 3.
7, and the other end I/i: # is hooked on the rotating body a9. Reference numeral 41 designates a pin-shaped operating body embedded in the lamp wick vertical shaft 34, and a bent portion 39c of a locking body 39b provided on the rotating body 39.

39d, and the rotating body 39 is pressed against the operating body 41 by the axial force of the fire extinguishing spring 40. Therefore, the rotating body 39 and the actuating body 41 are in close contact with each other so as to slide with a constant force. Furthermore, as shown in FIG. 4, the rotating body 39 is energized to rotate in the wick downward direction (in the direction of the arrow in FIGS. 3 and 4) by the extinguishing spring with stored force. The bending portion 39c of the provided locking body 39b engages with the operating body 41, and the wick vertical shaft 34 is rotated in the wick lowering direction (in the direction of the arrow). The stop body 39s provided on the rotating body 39 is located on the rotation trajectory of the actuating body 41, and has a high stopping surface so that the actuating body 41 temporarily stops when rotating in the direction of lowering the lamp wick. The actuating body 41 is configured to be tapered so that it can be pushed over the lamp wick when it is rotated in the upward direction of the lamp wick. Reference numeral 42 denotes a knob for raising and lowering the wick provided at the tip of the wick up and down shaft 34.

Reference numeral 43 denotes a vibration fire extinguishing device attached to the bearing fitting 37, which is operated by a weight 44 that senses vibration, and has a lever 45 that is always elastically engaged with the rotating body 39.

A part of this lever 45 is provided with a lock body 46 that engages with the engaging portions 39a, 39a' of the rotating body 39 as shown in FIGS. 1, 2, and 4. Due to the meshing of the rotary body 39 with the extinguishing spring 40, the rotary body 39 is prevented from rotating in the wick downward direction by the stored force of the extinguishing spring 40.

47 is a vibration extinguishing device board 43a together with the lever 45.
The lever 45 is actuated via bottles 48a and 48b installed in the arm portion 47a by a manual fire extinguishing body pivotably supported on the arm portion 47a.

In the above configuration, when the knob 42 is rotated in the wick upward direction, the rotating body 3
9 rotates, thereby increasing the power of the fire extinguishing spring 40. On the other hand, the rack 35 is driven by the pinion 34a, and the wick holder 33 and the lamp wick 32, which are integrally attached to the rack 35, are raised. When the lamp wick 32 reaches the highest position, the rise of the wick 32 is stopped. , 7'ゝ゛'''Oat!
1fa (;tc390%@"39°"' It engages with the locking body 46 of the vibration fire extinguishing device and prevents the wick from descending.The wick height at this time is the highest point in Figure 1 ■. The relative positions of the actuating body 41 and the rotary body 39 in the circumferential direction are as shown in FIG. ing.

Next, when lowering the wick to adjust the combustion state, when the knob 42 is rotated in the wick lowering direction (in the direction of the arrow), the actuating body 41 moves to the rotating body 39, as shown in FIG.
It rotates until it comes into contact with a stop body 39e provided at. The wick height at this time is the position shown in Figure 1 @, and the range from ■ to ◎ is regulated as the wick being adjusted. Since this is taken into consideration in advance to achieve a normal combustion height, incomplete combustion due to lowering the wick 32 too much will not occur.

Next, in order to further lower the wick 32 in order to extinguish the fire, by applying a rotational force stronger than the normal rotational force using the knob 42, the stop body 39e of the rotating body 39 is moved in the axial direction by the pressure of the operating body 41. Because the knob 42 moves freely (at this time, the rotating body engaging portion 39a also moves on the surface of the lock body 46, but does not come off from the lock body 46), the knob 42 can freely rotate, and the fourth As shown in Figure (0), the actuating body 4
1 rotates until it engages the bent portion 39d of the locking body 39b. The lamp wick position at this time is the position shown at θ in FIG. This wick position O is set at a position where the oil combustor can extinguish the fire within a time (approximately 300 seconds), which is generally considered safe if the fire is extinguished within this time. (hereinafter referred to as the first fire extinguishing position). In other words, the extinguishing time is extremely long compared to conventional ones, and the residual heat continues to burn the petroleum vapor that continues to evaporate from the top of the wick, significantly reducing odor. The above-mentioned combustion flame gradually weakens due to lack of air and naturally extinguishes within the above-mentioned time.

When the knob 42 is rotated in the wick upward direction in order to use it again, the actuating body 46 rotates along the taper of the stopper 39e and passes over the stopper 39e with less resistance than when the wick is lowered. Rotate to the highest point of height.

(Return to the state shown in FIG. 4 fal.) Next, a case will be described in which the fire can be extinguished more easily than by turning the fire by hand as described above. In this case, the manual fire extinguishing body 47 can be pushed in the direction of arrow B in FIGS. 1 and 2, thereby causing the manual fire extinguishing body 47 to displace the bottle 48a.

Lift lever 45 via 48b. Therefore,
FIG. 4 + (As shown in FIG. 11, the engaging portion 39a of the rotating body 39 and the locking body 46 of the lever 45 are disengaged, and the rotating body 39 is moved in the downward direction of the lamp wick (in the direction of the arrow) due to the biasing force of the extinguishing spring 44. This movement causes the actuating body 41-
The light is transmitted to the light wick up and down shaft 34, and the light wick is instantly lowered by the spring force trap.

The lowering position of the lamp wick 32 is the same as when the knob 42 is rotated by hand. That is, the locking body 46 of the lever 45 lifted by operating the manual fire extinguishing body 47 is engaged with a tall engaging portion 398' provided on the rotary body 39, as shown in FIG. 2fBj. The lowering position of the lamp wick 32 at this time is set to be O. Therefore, odor reduction can be achieved in the same way as extinguishing by rotating the front handle.

On the other hand, if the combustor is subjected to vibrations such as an earthquake or falls and receives an impact, the weight 44 of the vibration extinguishing device 430 tilts and the lever 45 is lifted.

The lifting position of the lever 45 at this time is the manual extinguishing body 4.
It reaches above the position of the lever 45 lifted at step 7. The rotating body 39 is rotated by the biasing force of the fire extinguishing spring 44, and at this time, the tall engagement portion 39a' of the rotating body 39 engages with the lever 450 lock body 46 as shown in FIG. 2 10). The rotating body 39 then rotates to its final position. At this time, the lowered position of the lamp wick 32 is O, which is deeper than θ at the first extinguishing position. Therefore, the fire is extinguished instantly, and the occurrence of abnormalities such as fire can be prevented. (Hereinafter, this will be referred to as the second fire extinguishing position.) At this time, a strong odor is generated, or ensuring safety is more important than the odor, and it does not occur often, so it is not a major problem.

Effects of the Invention As is clear from the description of the embodiments, the oil combustor of the present invention can quickly lower the wick and extinguish the fire with a simple one-touch operation by operating the manual fire extinguishing body, and moreover, it is possible to extinguish the fire by operating the manual fire extinguisher. When normally extinguishing a fire using a manual fire extinguishing element, the lowering stroke of the wick is short, so the fire does not extinguish instantly, and the fuel that continues to evaporate from the top of the wick is burned, so the extinguishing odor is greatly reduced, and the effect is impressive.
