Description

DETAILED DESCRIPTION OF THE INVENTION 2.-7 Field of Industrial Application The present invention relates to an oil combustor that is used by moving the wick up and down.

BACKGROUND OF THE INVENTION Conventional oil burners, such as oil stoves, have a burner section 2 on a tank 1, as shown in FIGS. 6 to 9.
A lamp wick 3, which is normally biased in the downward direction, is provided in the bar part 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 5 and a pinion 6. ing.

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 this lamp shaft 4, and a rotary plate 13 having a bottle 14 is attached to this. Further, the ratchet wheel 9 is provided with a through hole 15 at a position that engages with the bin 14, and the bin 14 is inserted into the through hole 15, and the lamp wick 3 is moved up and down within the range of the through hole 15, i.e. The amount of combustion can be adjusted and incomplete combustion due to lowering the wick 3 too much can be prevented. Furthermore, a vibration sensing device 16 is attached to the tank 1. This vibration feeling 3 base
The button device 16 includes a weight 17, a fire extinguishing knob 23, and a weight 1.
7. Consists of a lever 18 and the like operated by a fire extinguishing knob 23. The locking portion 21 at the tip of the lever 18 engages with the pawl 9N of the ratchet wheel 9, thereby preventing the ratchet wheel 9 from rotating in the wick downward direction. In addition, the pawl wheel 9
The maximum rotation range 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. 7 is a knob, which is fixed to the lamp shaft 4.

In the kerosene stove as described above, when the knob 7 is rotated upward and outward from the wick, the wick 3 rises through the wick shaft 4, rack 5, and pinion 6 while accumulating power. in this case,
The ratchet wheel 9 is caught by the frictional force of the friction members 10 and 11, and the lamp shaft 4
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, turn the knob 7 in the wick lowering direction (opposite to the wick rising direction), but the ratchet wheel 9 is locked in the locking part 21 and cannot be rotated. , the wick shaft 4 is a friction member IQ
, 11 and can rotate together with those members. Therefore, the wick height can be adjusted within the range of the through hole 15 in which the pin 14 can move.

Next, when extinguishing the lamp, the lamp wick is lowered by operating the lever 18 using the extinguishing knob 23 to disengage the locking part 21 from the pawl 9a, and the accumulated power of the lamp wick 3 is released and the lamp wick suddenly moves to the lowest position. It descends until the fire reaches a certain point 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 18. Therefore, fire extinguishing knobs 2 and 3
Similar to the fire extinguishing operation, the lamp wick 3 suddenly descends to the lowest position and extinguishes the fire instantly.

Problems to be Solved by the Invention In the conventional kerosene stove as described above, the wick 3 can be lowered with the knob 7 for raising and lowering the wick within the range of the through hole 15 provided in the ratchet wheel 9; In other cases, the wick can only be extinguished by rapid descent using the extinguishing knob 23 and the vibration sensing device 16. However, on page 6, there is an abnormal situation in which the wick 3 does not descend unless a force greater than the lowering force of the wick 3 is applied, for example, when tar, etc. forms at the tip of the wick 3 and adheres to the surrounding wick guide tube, etc. However, there was a problem in that the wick could not be lowered using the normal wick lowering power stored. 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 by 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, with the locking part 21 disengaged from the pawl 9'.
Furthermore, it is necessary to turn the wick upper and lower knobs 7 by hand, which is a problem in that it is very difficult to understand and difficult to operate in the event of an emergency fire extinguishment.

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 to Solve All Problems In order to solve the above-mentioned problems, the present invention provides a 6-head lamp with a head supported by an elastic body provided on the vertical axis of the lamp wick.

It consists of a stop body and an engagement groove provided on the inscribed surface of the wick upper and lower knob with the wick upper and lower shafts, and it temporarily stops the wick descent at a predetermined position, and when normally extinguishing, the wick upper and lower shafts extend beyond this point. It has a configuration that allows it to be operated by hand.

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 formed at the tip of the wick. The wick can be lowered by manually turning the wick top and bottom knobs. When extinguishing a fire, it is possible to detect all the hooks in the wick,
It can improve the safety of fire extinguishing.

EXAMPLE An example of the present invention will be described below with reference to all the drawings. FIG. 1 is a side sectional view of an oil combustor according to an embodiment of the present invention, FIGS. 2 and 3 are sectional views of the main parts, and FIG. Figure 5a-
d shows a sectional view taken along line XX in FIG.

In Figures 1 and 5 on page 7, 30 is a tank, 31 is a burner section installed in the tank, and 32 is a wick holder attached to the burner section 31.
The lamp wick attached via the wick 33 can be freely raised and lowered between the wick guide tube 312L and the wick guide tube 312L.

34 is a wick vertical axis and has a pinion 34ai at its tip, and this pinion 34a is engaged with a rank 35 provided on the wick holder 33 to move the wick 32 up and down. Further, the lamp wick vertical shaft 34 can slide only in the axial direction in the middle, and is divided into a front shaft 34b and a rear shaft 340 so that power can be transmitted in the rotation direction.
2 has an interior. 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 plate-shaped rotating body made of polyacetal resin or the like, which has a plurality of retaining parts 3911 on its periphery and is rotatably fitted into the lamp wick vertical shaft 34, and has a fixed distance on the inner circumferential surface of the shaft hole 47. The engaging grooves 48 and 49 are provided offset in the axial direction, and these grooves are integrally connected by an axial communication groove 60.

Reference numeral 40 designates a fire extinguishing spring for lowering the wick, which is positioned between the rotating body 39 and the bearing fitting 37 and fitted around the wick vertical shaft 34, and is pre-wound in advance, with one end attached to a part of the bearing fitting 37. The other end is hooked to the rotating body 39. The fire extinguishing spring 40 only applies rotational force to the rotating body 39, but does not have any biasing force in the direction of the lamp wick vertical axis 34. Reference numeral 41 denotes a stop body provided in the recess 53 of the front shaft 34b of the core vertical shaft 34 via an elastic body 64, and the engagement groove 4 provided in the shaft hole 47 of the rotating body 39.
8.49, it engages and slides within the communication groove 60. Therefore, the rotating body 39 is energized to rotate in the wick downward direction (in the direction of arrow C in FIGS. 4 and 5 a - d) by the extinguishing spring 40 with stored force as shown in FIG. 6. Then, the stop body 41 of the front shaft 34b of the lower shaft 34 engages the engaging grooves 48 and 49 provided on the rotating body 39, the communication groove 50, and the wick, and the wick vertical shaft 34 is engaged with the wick in the entire wick descending direction (direction of arrow C). You can now rotate it to Reference numeral 42 denotes a lamp wick upper/lower knob 1 provided at the tip of the wick upper/lower shaft 34.

43 is a vibration sensing device attached to the bearing fitting 37;
' It is operated by a weight 44 that senses all vibrations, and has a lever 45 that is always resiliently engaged with the rotating body 39.

A part of the lever 46 is provided with a locking body 46 that engages with the engaging portion 39a of the rotating body 39, as shown in FIGS. 1 and 6. Therefore, the rotating body 39 is prevented from rotating in the wick downward direction by the accumulated force of the fire extinguishing spring 40.

2, when the knob 42 is rotated in the wick upward direction, the rotary body 39 rotates via the wick vertical shaft 34 and the stop body 41 engaged with the engagement groove 49 of the rotary body 39. This allows the fire extinguishing spring 40 to accumulate more power and the stop body 4
1 moves from the engagement groove 49 to the engagement groove 48 through the communication groove 60 by the force of the elastic body 62. On the other hand, the rack 36 is driven by the pinion 34L, and the wick holder 33 and the lamp wick 32, which are integrated with the rack 36, are raised. When the lamp wick 32 reaches the uppermost position, the lifting of the lamp wick 32 is stopped, and at this position, the retaining portion 39a of the rotating body 39 engages with the locking body 46 of the vibration sensing device, completely preventing the lamp wick from descending.

10.

The wick height at this time is the highest point in Figure 1 (■).

Further, the relative positions of the stop body 41 and the rotary body 39 in the circumferential direction at this time are as shown in FIG.
is engaged with one end of the engagement groove 48 .

Next, in order to adjust the combustion condition, the wick is lowered completely.
To lower the wick, turn the wick lower knob 42 in the wick lowering direction (in the direction of arrow C), and as shown in FIG.
1 rotates until it locks with the other end of the engagement groove 48 provided in the rotating body 39. At this time, the wick height is at the position shown in FIG. 1 @, and the range from ■ to O-1 is regulated as wick adjustment 1]. 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.

To further lower the wick 32 to extinguish the fire, the sixth
At the position shown in the figure, the stop body 41 of the core vertical shaft 34 is moved by moving the core upper and lower knobs 42 in the axial direction through the communication groove 50 against the elastic body 62 and rotating them together with the engagement groove 491 at the back. (At this time, the engaging portion 391L of the 11-n rotating body 39 is designed not to come off the lock body 46.) The core upper and lower knobs 42 can now be rotated freely, and as shown in FIG. 6C. As shown, the stop body 41 rotates at 1, which engages the terminal end of the engagement groove 49. The lamp wick position at this time is the position shown at θ in FIG. This wick position θ
is set in such a position that the fire can be extinguished within the time (approximately 300 seconds), which is generally considered safe for oil combustors. (Hereinafter, this will be referred to as the first fire extinguishing position). In normal use, the lamp wick position is as shown above.
~ θ, turn the wick up/down knob 42 in the wick upward direction to raise the wick 32 to the uppermost position ■, ignite it here, and then burn the combustion tube (not shown, mounted on the burner section 31). The height of the wick 32 is adjusted within the range of ■~O in order to obtain the optimum combustion condition.

To extinguish the fire, first move the knob 42 in the axial direction and then rotate it a thousand times in the direction of the wick descending.
The lamp 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 41 rotates along the engagement groove 49, communication groove 50, and engagement groove 48, and the wick height is increased. Rotate to the highest point ■. (Returns to the state shown in Figure 5a.) 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 As shown in FIG.
The lock body 46 is disengaged, and the rotating body 39 attempts to rotate in the wick downward direction (in the direction of arrow C) due to the urging force of the fire extinguishing spring 40, and this movement causes the stop body 41 to rotate the wick vertical axis 34.
This message is transmitted, and the spring force instantly lowers the wick. This rotation is more than when the wick upper and lower knobs 42 are turned by hand, and the wick position is also at O in Figure 1, which is higher than θ at the first extinguishing position. It descends deeply. 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.) In the above embodiment, the lever 46 is operated by the weight 44 and the rotating body 39 is engaged only when the vibration sensing device 43 is activated due to vibration impact. Although the structure is designed to disengage the engagement portion 39a and the lock body 46, a mechanism for manually operating the lever 45 is provided, and by fully operating this mechanism, the engagement between the rotating body 39 and the lock body 46 is disengaged. It may also be a configuration. 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 extinguishing the fire instantly. 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 that restricts the wick to a normal combustion height range, so that there is no possibility that the wick metalwork will be too high and cause incomplete combustion. In addition, when extinguishing a normal fire, the above-mentioned normal combustion range is completely lifted by a strong manual turning force, so even if there is tar etc. on the tip of the wick, the wick can be lowered easily with normal operation, and you can feel it securely. It is possible to confirm that the fire is completely extinguished. Further, since the above-mentioned release of restriction is carried out by moving the rotating body in the axial direction, there is no damage to the restricting part, and there is an advantage that it can be used satisfactorily for a long period of time.
