CONSTITUTION:When the upper and lower knob 42 of the wick is pivoted to the wick descending direction, the stopping body 47 is pivoted until abutting to the end tip of the engaging hole 50 provided on the rotating body 39. The height of the wick is the position showing (b) at this time and the space from (a) to (b) is regulated as the wick control width while it is controlled so as to becomes to the height of the normal combustion in advance, therefore, an incomplete combustion caused by over-descending of the wick 32 is not generated. When stronger pivoting power than normal power thereof is applied to the knob 42 to extinguish the fire, the stopping body 47 of the wick upper and lower shaft 34 is moved to exceed the engaging hole 50 to the concave part 34b inner direction due to deformation of an elastic body 48 while the knob 42 may be pivoted until the position in which the operation body 41 abutes against a bending part 39d.

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.

2. Description of the Related Art In a conventional oil burner, such as an oil stove, a burner section 2 is mounted on a tank 1, as shown in FIGS. 6 to 8.
A lamp wick 3 which is normally biased in the downward direction is provided in the burner section 2 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 6 and a pinion 6. There is.

Then, a ratchet wheel 9 is attached to the lamp shaft 4 with a friction member 10°11.
Further, a holder 8 is fixed to the lamp shaft 4, and a rotary plate 13 having a pin 14 is attached to this. Further, the ratchet wheel 9 is provided with a through hole 16 at a position that engages with the pin 14, and the pin 14 is inserted into the through hole 16.
The vertical movement of the wick 3, that is, the amount of combustion can be adjusted within the range of the through hole 16, and incomplete combustion due to lowering the wick 3 too much is prevented. Furthermore, a vibration sensing device 16 is attached to the tank 1. This vibration sensing device 16
is composed of a weight 17, a fire extinguishing knob 23, a lever 18 operated by the weight 17 and the fire extinguishing knob 23, and the like. The locking portion 21 at the tip of the lever 18 engages with the pawl 9a of the ratchet wheel 9 to prevent 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 where the protrusion 9b provided on the ratchet wheel 9 hits the locking portion 21, that is, the range of one rotation, and the lamp wick 3 moves up and down within this range. It is something. 7 is a lamp, which is fixed to the lamp shaft 4.

In the kerosene stove as described above, when the knob 7 is rotated in the direction in which the wick rises, the wick 3 rises through the wick shaft 4, the rack 6, and the pinion 6 while accumulating power. in this case,
The ratchet wheel 9 is moved against the wick shaft 4 by the frictional force of the friction members 10 and 11.
rotates with. When the operating force on the ratchet wheel 9, that is, the operating force on the knob 7 is released, the pawl 9a is engaged with the locking portion 21, and the lamp wick 3 is held at a predetermined height. Next, to adjust the wick height, rotate the knob 7 in the wick lowering direction (opposite to the wick ascending direction). Although it is not possible, the wick shaft 4 is connected to the friction member 10.
, 11 and can rotate together with those members. Therefore, the height of the wick can be adjusted within the range of the through hole 15 through which the bottle 14 can move.

Next, the lowering of the lamp wick when extinguishing is normally carried out by operating the lever 18 using the extinguishing lever 23 to release the locking part 21 from the pawl 9a, and the accumulated power of the lamp wick 3 is released and the lamp wick suddenly reaches its maximum level. It descends to the lower position and instantly extinguishes the fire. On the other hand, if an abnormality occurs, for example, an earthquake occurs during use, the weight 17 senses this and operates the lever 11B. Therefore, similar to the extinguishing operation using the extinguishing knob 23, the lamp wick 3 is suddenly lowered to the lowest position and extinguished instantly.

Problems to be Solved by the Invention In the conventional kerosene stove as described above, the wick 3 can be lowered with the wick upper and lower knobs 7 within the range of the through hole 16 provided in the ratchet wheel 9; 6. When the wick falls outside the
The only way to extinguish the fire is by sudden descent. Therefore, if you do not apply a force greater than the descending force of the wick 3, the wick 3 will fall and an abnormality will occur. For example, if tar or the like forms at the tip of the wick 3 and adheres to the surrounding wick guide tube, the normal There was a problem in that the wick could not be lowered with the wick lowering power stored. Moreover, if the lamp wick 3 is caught in a position where it cannot be extinguished, the combustion will continue even if you intend to extinguish the fire with the extinguishing knob 23, creating a very dangerous situation. In other words, in the state in which the locking part 21 is released from the pawl 9a, it is necessary to further turn the core upper and lower knobs 7 by hand, which is extremely difficult to understand and perform in the event of an emergency fire extinguishment. There were also problems.

The present invention was 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.

Means for Solving the Problems In order to solve the above problems, the present invention provides a stop body with a retractable head supported by an elastic body provided on the vertical axis of the wick, and a recess for the top and bottom of the wick. It consists of an engagement hole made in the inscribed surface of the lamp wick's upper and lower shafts, and it is configured to temporarily stop the wick's descent at a predetermined position, and when normally extinguishing, it can be done by manually turning the wick's upper and lower knobs. It is prepared.

Effect of the present invention With the above-described configuration, it is possible to prevent incomplete combustion due to lowering the wick too much, and when a force greater than the lowering force of the wick is required, for example, when tar etc. are generated at the tip of the wick, The wick can be lowered by manually turning the wick top and bottom knobs. In addition, when extinguishing a fire, it is possible to detect if the wick is caught.
It can improve the safety of fire extinguishing.

Embodiment is an exploded perspective view of main parts in one embodiment of the present invention, and FIG. 3 is a sectional view of main parts of regeneration. In Fig. 1, 7 to -30 are tanks, 31 is a burner section equipped on the tank, and 32
A lamp wick is attached to the burner portion 31 via a wick holder 33, and is freely raised and lowered between the wick guide tube 31a and the wick. 34
The lamp wick vertical shaft has a pinion 34Ta at its tip, and this pinion 34& is engaged with a rack 36 provided on the wick holder 33 in order to move the lamp wick 32 up and down. Reference numeral 36 denotes a bearing for supporting the lamp vertical axis, which is fixed to the tank 30, and numeral 37 denotes a bearing fitting that supports the lamp vertical axis packing 38, etc., which is fixed to the tank 30. 39 is a disc-shaped rotating body made of polyacetal resin or the like, which has a plurality of retaining parts 391L on its periphery and is rotatably fitted into the lamp wick vertical shaft 34, and a locking body having bent parts 39C139d at both ends. 3
9b is provided concentrically on one surface of the rotating body 39 by integral molding. Reference numeral 40 denotes a fire extinguishing spring for lowering the lamp wick, which comes into contact with the rotating body 39 and the bearing fitting 37 and is fitted around the lamp vertical axis 34, and is pre-wound in advance, and one end is attached to the bearing fitting 37.
The other end is hooked to the rotating body 39. 4
Reference numeral 1 denotes a bottle-shaped actuating body embedded in the lamp vertical shaft 34, which is positioned so that it can rotate between the bent parts 390 and 39d of the locking body 39b provided on the rotary body 39, and the actuating body 1 is located so that it can rotate between the bent parts 390 and 39d of the locking body 39b provided on the rotating body 39. Due to the axial force of the shaft 34, the rotating body 39
is being oppressed by this actuating body 41. 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. Further, the rotating body 39 is energized to rotate in the direction of the lamp wick descent (in the direction of arrow A in FIGS. 1 and 4) by a fire extinguishing spring 40 with stored power as shown in FIGS. 4a and 4d. , the bending portion 39C of the locking body 39b provided on the rotating body 39 engages with the actuating body 41, and the wick vertical shaft 34 is moved in the wick descending direction (
direction of arrow A).

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 sensing device attached to the bearing fitting 37, which is operated by a weight 44 for sensing vibration, and has a lever 46 that is always elastically engaged with the rotating body 39.

A part of this lever 46 is provided with a lock body 46 that engages with the engaging portion 39a of the rotating body 39, as shown in FIGS. 1 and 4.
Due to the engagement with the fire extinguishing spring 40, the rotating body 39 is
This prevents the wick from rotating in the downward direction.

Reference numeral 47 denotes a stop body provided in the four parts 34b of the lamp wick vertical shaft 34 via an elastic body 48 so as to be freely retractable.
It comes into elastic contact with the inner surface and slides into a triangular engagement hole 60 provided along the circumferential direction of the inner surface, thereby setting the core height in this range to the position shown in FIG.

In the above configuration, when the wick up and down knob 42 is rotated in the wick upward direction, the wick up and down shaft 34 and the locking body 3 of the rotating body 39
The rotating body 39 rotates via the actuating body 41 that is in contact with the bent portion 39c of the fire extinguishing spring 4o, thereby increasing the power stored in the fire extinguishing spring 4o. On the other hand, the rack 36 is driven by the pinion 342L, and the wick holder 33 and the lamp wick 3 are integrated with the rack 36.
Raise 2. And when it reaches the top position, the wick 32
stops rising, and at this position the engaging portion 3 of the rotating body 39
9& engages with the locking body 46 of the lever 45 of the vibration sensing device, as shown in Fig. 4B, and prevents the lamp wick from descending. The wick height at this time is the highest point in Figure 1 (■). Further, at this time, the relative positions of the actuating body 41 and the rotating body 39 in the circumferential direction are as shown in FIG. I'm right.

Next, when lowering the wick to adjust the combustion state, when the wick upper/lower lever 42 is rotated in the wick lowering direction (in the direction of the arrow), the stop body 47 is moved as shown in FIG. 4('b). It rotates until it engages with the terminal end of the engagement hole 6o provided in the rotating body 39. At this time, the wick height is at the position shown in Figure 1 @.
The period from ■ to @ is regulated as the lamp 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 47 of the wick vertical shaft 34 is deformed by the elastic body 48, and the four parts 3ab The engaging hole 60 of the rotating body 39 is moved inward (at this time, the rotating body retaining portion 39a also moves to the surface of the opening 11 and the locking body 46, but does not come off from the locking body 46). As a result, the lever 42 can be freely rotated, and as shown in FIG. The lamp wick position at this time is the position shown in Figure 1 O.This lamp wick position O is within the time (approximately 300 seconds) which is generally considered safe if the oil combustor extinguishes within this time. It is set at a position where it can extinguish the fire (hereinafter referred to as the first extinguishing position).In normal use, the wick position is in the range of ■ to θ mentioned above, and the wick is set at a position where the upper and lower ends of the wick are set at 42. direction, raise the wick 32 to the uppermost position, and ignite it here.
The height of the wick 32 is set to ~~ in order to achieve the optimum combustion condition for combustion in the combustion tube (not shown, mounted on the burner section 31).
Adjust within the @ range. To extinguish the fire, the knob 42 is rotated by hand in the wick downward direction with even stronger rotational force, and the wick 32 is lowered to the θ position (first extinguishing position) and extinguished.

Then, in order to use it again, when the wick upper and lower puller 42 is rotated in the wick upward direction, the stop body 47 rotates along the inner surface of the engagement hole 39C, and the wick is raised with less resistance than when the wick is lowered. The highest point ■ Rotate with the sword. (Returns to the state shown in Fig. 4 (a).) On the other hand, if the combustor is subjected to vibrations such as an earthquake or falls and receives an impact (in an abnormal situation), the vibration sensing device 43 is activated and the As shown in figure (d), the rotating body 3
9 is disengaged from the lock body 46, and due to the urging force of the extinguishing spring 44, the rotating body 39 attempts to rotate in the wick downward direction (in the direction of arrow A), and this movement causes the actuating body 4 to rotate.
1 → The light is transmitted to the wick up and down shaft 34, and the spring force instantly lowers the wick. This rotation is more than when the wick upper and lower puller 42 is rotated by hand, and the wick position is also O in Figure 1, which is the first extinguishing position. It descends deeper than θ. 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 extinguishing position) 13 Vane In the above embodiment, only when the vibration sensing device 43 is activated due to vibration impact, the lever 46 is operated by the weight to lock the rotating body 39. Although the configuration is such that the engagement between the portion 39a and the lock body 46 is disengaged, a mechanism for manually operating the lever 46 is provided, and by operating this, the rotating body 3
9 and the lock body 46 may be disengaged. In this case, in the event that abnormal combustion occurs during normal use, by operating this mechanism, the wick can be lowered rapidly to the second extinguishing position, which has the additional effect of instantly extinguishing the fire. It is.

Effects of the Invention As is clear from the description of the embodiments, the oil combustor of the present invention has a mechanism for regulating the wick within the normal combustion height range, so that incomplete combustion cannot occur if the wick is lowered too far. In addition, when normally extinguishing a fire, the above-mentioned normal combustion range is lifted using a strong manual turning force, so even if tar or the like forms on the tip of the wick, the wick can be lowered easily with normal operation, ensuring that the wick can be This allows you to confirm that the fire has been extinguished. Further, since the above-mentioned release of restriction is performed between the shaft hole of the rotating body and the upper and lower shafts of the lamp wick, there is no damage to the restricted portion, and there is an advantage that the lamp can be used satisfactorily for a long period of time.
