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.

Structure of a conventional example and its problems In a conventional oil burner, for example, an oil stove, a burner section 2 is installed on a tank 1, and a A lamp wick 3 which is normally biased in the downward direction is provided so as to be able to move up and down freely, and the lamp wick 3 is moved up and down by a lamp shaft 4 via a rack 5 and a pinion 6.
Then, a ratchet wheel 9 is attached to the friction member 1 on the lamp shaft 4.
Further, a holder 8 is fixed to this lamp shaft 4, and a rotary plate 13 having a pin 14 is attached thereto, and a through hole is provided in the ratchet wheel 9 at a position where it engages with the pin 14. 15 is provided, and a pin 14 is inserted into this through hole 15, so that the vertical movement of the lamp wick 3, that is, the combustion amount can be adjusted within the range of the through hole 15, and incomplete combustion due to lowering the lamp wick 3 too much can be prevented. It's getting old. Furthermore, a vibration sensing device 16 is attached to the tank 1. This vibration sensing device 16 includes a weight 17 and a fire extinguishing knob 23, and a lever 1 operated by the weight 17 and the fire extinguishing knob 23.
It is composed of 8 mag. And the above lever 1
8 engages with the pawl 9' of the ratchet wheel 9, and prevents the ratchet wheel 9 from rotating in the wick downward direction. The maximum rotation range of the ratchet wheel 9 is defined as the range in which the protrusion 9'' provided on the ratchet wheel 9 hits the locking portion 21, that is, the range of one rotation, and the lamp wick 3 does not move up or down within this range. 7 is a knob, which is fixed to the lamp shaft 4.

In the above-mentioned kerosene stove, when the knob 7 is rotated in the direction of raising the wick, the wick 3 is raised through the wick shaft 4, the rack 5, and the pinion 6 while accumulating power. In this case, the ratchet wheel 9 is the friction member 1
It rotates together with the lamp shaft 4 due to the frictional force of 0.11. Then, when the operating force on the ratchet wheel 9, that is, the operating force on the knob 7 is released, the pawl 9' is engaged with the locking portion 21, and the lamp wick 3 is held at a predetermined height. Next, when adjusting the wick height, rotate the knob 7 in the wick lowering direction (opposite to the wick raising direction).
Although the ratchet wheel 9 is locked by the locking portion 21 and cannot be rotated, the lamp shaft 4 can overcome the frictional force of the friction members 10 and 11 and can rotate together with these members. Therefore, within the range of the through hole 15 in which the pin 14 can move,
The wick height is adjustable.

Next, when extinguishing, the lamp wick is lowered by operating the lever 18 using the extinguishing knob 23 at the locking part 21.
When the lamp wick 3 is disengaged from the claw 9', the power stored in the lamp wick 3 is released and the lamp wick suddenly descends to the lowest position, extinguishing the fire instantly. On the other hand, if an abnormality occurs, for example, an earthquake occurs during use, the weight 17 senses this and operates the lever 18. Therefore, similar to the extinguishing operation using the extinguishing knob 23, the lamp wick 3 suddenly descends to the lowest position and extinguishes the fire instantly.

In the conventional kerosene stove as described above,
The wick 3 can be lowered with the wick up/down knob 7 within the range of the through hole 15 provided in the ratchet wheel 9, and the wick can only be lowered in other places by rapidly dropping and extinguishing with the extinguishing knob 23. There is a drawback that if tar or the like forms at the tip of the wick 3 in excess of the accumulated power for descent, the wick cannot be lowered. Moreover, if the wick 3 is caught in a position where it cannot be extinguished, the combustion will continue even if the fire is extinguished using the extinguishing knob 23.
This is a very dangerous situation, and in this case, the extinguishing operation is to operate the fire extinguishing knob 23, that is, to disengage the locking part 21 from the pawl 9', and then to operate the core upper and lower knobs 7. It had to be turned by hand, making it extremely difficult to understand and perform in an emergency situation where the fire could not be extinguished.

Purpose of the Invention The present invention has been made in view of the above-mentioned problems, and aims to detect whether the wick is lowered too much during combustion and to improve fire extinguishing safety.

Structure of the Invention In order to achieve the above object, the present invention temporarily stops the wick descent at a predetermined position, and when normally extinguishing, the wick is turned beyond this point by manually turning the upper and lower knobs of the wick.

6, 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 freely raised and lowered between it and the wick guide tube 31a. . 34 is a lamp wick vertical axis, which has a pinion 34a at the tip.
This pinion 34a is used to move the lamp wick 32 up and down.
is provided with inclined grooves 35a and 36a into which a pin 33a from a lead holder 33 is inserted.
It is engaged with a rack 37 provided at 6. 38 is a bearing for supporting the upper and lower shafts of the lamp wick provided in the burner part 31;
39 is a rotating body having a plurality of engaging portions 39a on its periphery, and is rotatably inserted into the lamp wick vertical shaft 34, and fixes the shaft body 40. 41 is a locking body fixed to the rotating body 39 with rivets 42 and 43;
A notch 41a is provided in a part. Reference numeral 44 denotes a fire extinguishing spring for lowering the lamp wick, which is fitted into the shaft body 40 of the rotating body 39, and is pre-wound in advance so that one end is attached to a part of the burner section 31 and the other end is attached to one of the rivets 43.
It's hooked up to. Reference numeral 45 denotes a rotary plate which is rotatably inserted into the lamp wick vertical shaft 34 so as to be located within the locking body 41, and has a bent portion 45a and a protruding portion 45b. The rotary plate 45 is provided such that its protrusion 45b is located in the cutout 41a of the locking body 41, and is rotatable within the range of the cutout 41a.

A pin-shaped actuating body 46 is embedded in the lamp vertical shaft 34 so as to be in contact with the rotary plate 45.
Due to the axial biasing force of the fire extinguishing spring 44, the operating body 46, rotary plate 45, and locking body 41 are brought into close contact so as to slide. As shown in FIG. 7, the small end 41b of the locking body 41 and the small end 41b of the locking body 41 are energized to rotate in the downward direction of the lamp wick and in the direction of arrow A in FIGS. Rotating plate 45
The protrusion 45b of the rotating plate 45 engages, and the bending portion 45a of the rotating plate 45 engages the actuating body 46.
The lamp is rotated in the wick lowering direction (arrow A direction). 47 is the small end 4 of the locking body 41
A stop body made of a spring material fixed to the lamp 1b, and its tip 47a is located on the rotation trajectory of the actuating body 46, and is configured such that the actuating body 46 temporarily stops when the lamp wick rotates in the downward direction. Further, when the lamp wick is rotated in the upward direction, the actuating body 46 is configured to push over the lamp wick while applying pressure.

Reference numeral 48 denotes a knob for raising and lowering the lamp wick screwed to the tip of the lamp wick upper and lower shaft 34.

Reference numeral 52 denotes a vibration sensing device attached to a part of the burner section 31, and has a lever 53 which is operated by a weight (not shown) for sensing vibrations and is always resiliently engaged with the rotating body 39. A lock body 54 that engages with the engaging portion 39a of the rotating body 39 is attached to the tip of the lever 53 as shown in FIG. The accumulated force of 44 prevents the rotating body 39 from rotating in the wick downward direction.

In the above configuration, when the knob 48 is rotated in the wick upward direction, the wick vertical shaft 34, the operating body 46,
The rotating body 39 rotates via the rotating plate 45 and the locking body 41, thereby increasing the power of the fire extinguishing spring 44. On the other hand, the rack 37 is driven by the pinion 34a, rotates the outer cylinder 36 that is integrated with the rack 37, and the driving pin 33 is rotated by the intersecting grooves 35a and 36a.
a upwardly, and thereby the lead holder 3
3. Raise the lamp wick 32. And drive pin 3
When the lamp 3a reaches the uppermost position of the intersecting grooves 35a and 36a, the lifting of the lamp wick 32 is stopped, and at this position, the appropriate engaging portion 39a of the rotating body 39 engages with the locking body 54 of the vibration sensing device, preventing the lamp from descending. prevent. The wick height at this time is the highest point in Figure 5A.

The relative positions of the above parts in the circumferential direction are as shown in FIG.
a is engaged, and furthermore, the protrusion 45b and the locking protrusion 41c of the locking body 41 are engaged.

Next, when lowering the wick to adjust the combustion state, when the knob 48 is rotated in the wick lowering direction (in the direction of arrow A), the actuating body 46 engages the stop provided on the locking body 41, as shown in FIG. 7b. Tip 4 of body 47
Rotate until it engages with point 7a. At this time, the lamp wick height is at the position shown in FIG. 5B, and the range from A to B is regulated as the lamp wick adjustment width. Since this is taken into consideration in advance to ensure normal combustion height, incomplete combustion due to lowering the wick 3 too much will not occur.

Next, in order to further lower the wick 32 in order to extinguish the fire, apply a rotational force stronger than the normal rotational force using the knob 48, so that the tip 47a of the stopper 47 is moved in the outer circumferential direction by the pressure of the actuator 46. In order to move, the knob 48 can now be rotated freely.
As shown in FIG. 7c, the actuating body 46 engages with the end 45c of the rotating plate 45, and
5b rotates until it engages the small end 41b of the locking body 41. The lamp wick position at this time is the position shown in FIG. 5C. This wick position C is set at a position where the fire can be extinguished within the time (approximately 300 seconds), which is generally considered safe if the oil combustor extinguishes within this time (hereinafter referred to as the first extinguishing position). ). In normal use, the lamp wick position is between
The knob 48 is rotated in the wick upward direction to raise the wick 32 to the uppermost position A, where it is ignited and burned in the combustion tube (not shown, mounted above the burner section 31). In order to obtain the optimum combustion condition, the height of the wick 32 is adjusted within the range of A to B.
To extinguish the fire, turn the knob 48 by hand in the downward direction of the wick with even stronger rotational force.
The wick 32 descends to position C (first extinguishing position),
It is meant to extinguish a fire.

Then, when the knob 48 is rotated in the wick upward direction in order to use it again, the operating body 46 moves to the stop body 47.
The lamp rotates along the wick, exceeds the stop body 47 with less resistance than when the wick is in the downward direction, and rotates to the highest point A of the wick height. (Returns to the state shown in Fig. 7a.) On the other hand, if the combustor is subjected to vibrations such as an earthquake or falls and receives shock (in an abnormal situation), the vibration sensing device 52 is activated and As shown in the figure, the engagement portion 39a of the rotating body 39 and the locking body 54 are disengaged, and due to the urging force of the fire extinguishing spring 44, the rotating body 39
tries to rotate in the wick lowering direction (in the direction of arrow A), and this operation is transmitted to the locking body 41 → rotary plate 45 → operating body 46 → wick vertical shaft 34, and the spring force instantly lowers the wick. This rotation is more than when the knob 48 is rotated by hand, and the lamp wick is in position 2.
It descends deeper than C at the first extinguishing position. Therefore, the fire can be extinguished instantly, and the occurrence of abnormalities such as fire can be prevented.
(Hereinafter, this will be referred to as the second extinguishing position.) In the above embodiment, only when the vibration sensing device 52 is activated due to vibration impact, the lever 53 is operated with a weight, and the engaging portion 39a of the rotating body 39 is activated.
Although the structure is such that the lock body 54 is disengaged, a mechanism for manually operating the lever 53 is provided,
By operating this, the rotation body 39 and the lock body 54 may be disengaged. In this case, if abnormal combustion occurs during normal use,
By operating this mechanism, the wick can be lowered rapidly to the second extinguishing position, which also has the additional effect of instantaneously extinguishing the fire.

Effects of the Invention Since the invention has a mechanism that regulates the wick within the normal combustion height range, there is no possibility of lowering the wick too much and causing incomplete combustion, and for normal extinguishing, the regulating mechanism must be controlled by a strong manual turning force. Therefore, even if tar or the like forms on the tip of the wick, the wick can be easily lowered by normal operation, and the extinguishment can be reliably confirmed by touch.
