Description

DETAILED DESCRIPTION OF THE INVENTION (a) Field of Application of the Invention The present invention relates to a wick up-and-down type combustion device in which the wick can be raised to the combustion position with a single touch by operating a wick raising lever.

(b) Prior art and problems The lamp wick is raised to the combustion position with one touch by the downward movement of the operating button, and the lamp wick raised to the combustion position is held by a locking plate of the seismic sensing device. In the event of an emergency fire extinguishment such as an earthquake, the seismic sensing device is activated, its locking plate releases the raised wick, and the elastic force of the wick lowering spring causes the wick to fall rapidly to the extinguishing position, extinguishing the fire. Even during normal extinguishing, there is a lever dedicated to extinguishing, which activates the locking plate of the seismic device, and a wick lowering spring is used to lower the wick and extinguish the wick. Combustion devices are known from Japanese Patent Application Laid-Open No. 58-35311 and Japanese Utility Model Application No. 58-46911.

By the way, in the conventional device described above, only the elastic force of the wick lowering spring acts as a force for lowering the wick, so carbon accumulates at the upper end of the wick due to long-term use or due to the use of degraded kerosene. If the lamp hardens, the elastic force of the wick lowering spring cannot lower the wick, causing various problems. One of these is the problem of not automatically extinguishing the fire even though the seismic device is activated during an earthquake or other shaking.The other problem is that the wick does not come down even though the fire was normally extinguished by operating the fire extinguishing lever. It burns forever with a small flame,
The problem was the generation of a large amount of CO due to incomplete combustion.

(c) Purpose of the Invention The present invention has been made in view of the above-mentioned problems. Carbon accumulates at the upper end of the lamp wick due to long-term use or the use of erroneously degraded kerosene, causing the wick to fail when extinguished. To provide a wick up-and-down type combustion device in which the wick can be lowered by a simple operation without damaging a locking means even when the wick is not lowered automatically.

(d) Structure of the Invention In order to achieve the above object, the present invention provides a wick up-and-down axis for moving the wick up and down, a wick-lifting lever for rotating this wick up-down axis in a direction in which the wick rises, and a wick-lifting lever for rotating the wick up-and-down axis in the direction in which the wick rises. a wick lowering spring that accumulates force and rotates the wick vertical axis in a direction in which the wick descends;
A means for locking the wick raised by the wick raising lever at the combustion position, and a fire extinguishing means for releasing the locking by this means and lowering the wick using the accumulated force of the wick lowering spring. In this type of wick up-and-down type combustion device, a mechanism is provided separately from the extinguishing means to release the lock of the wick and manually rotate the wick up-down axis in the direction in which the wick descends.

Although the support plate 58 is attached to the shaft support board 22 with screws or the like, it may be formed integrally with the shaft support board 22.

The configuration of the present invention is as described above, and next, the operation of the above configuration will be explained.

(When igniting) First, when the operation button 46 is pushed down in the direction of arrow A in FIG. (See Figure 9). The rotation of the interlocking lever 45 causes the roller 48 to move the latch shaft 29 in the direction of arrow B in FIG. is rotated counterclockwise through an angle of about 60 degrees, and as the rotation plate 23 is rotated, the wick vertical shaft 14 and the arm plate 16 are rotated in a direction in which the lamp wick 11 is raised. Further, as the wick 11 rises, the wick lowering spring 21 is compressed to accumulate elastic force for lowering the wick 11, and the latch shaft 29 moves as shown in FIG. As shown, the locking pawl 33' of the latch 33 locks on the locking shaft 37 of the locking plate 36, and the lamp wick 11 has completed its rise from the extinguishing position to the combustion position and is in its raised state. will be retained.

On the other hand, the other end of the wick lifting lever 47 operates the ignition mechanism 48 at the same time as the wick 11 is raised, and the ignition mechanism 48 lifts the combustion tube 4 and attaches the ignition heater 49 to the tip of the raised wick 11. Bring them close together and ignite them by applying electricity.

(Adjustment of combustion) The raised lamp wick 11 can be adjusted by rotating the rotary knob 32. In other words, when the rotation knob 32 is rotated, the latch shaft 29
The rotation of the latch shaft 29 causes the latch shaft movable body 27 screwed to the male thread 43 to move in the axial direction (in the direction of arrow D in FIG. 8). The movement involves rotating the wick vertical shaft 14 by a small rotation angle (approximately 5 to 6 degrees) through the rotation plate 32, and the lamp wick 11 can be raised and lowered by a vertical movement range of approximately 6 to 7 mm. This slight rotation of the wick vertical shaft 14 finely adjusts the height of the wick 11 at the combustion position.

(For normal fire extinguishing) Next, to explain normal fire extinguishing, press down on the extinguishing button 51 and move the extinguishing lever 50 to the vertical axis 14.
By rotating the fire extinguishing lever 50 with the pivot pin 42 as the pivot point, the other end of the fire extinguishing lever 50 moves upward, and the locking plate 36 rotates with the pivot pin 42 as the pivot point, whereby the locking shaft 37
The locking pawl 33' of the latch 33 that is engaged with the latch 33 is disengaged, and the latch shaft 29 becomes movable.
At this time, the lamp wick 11, which is in the combustion position, is suddenly lowered to the extinguishing position by the elastic force of the wick lowering spring 21, and is extinguished. When the lamp wick 11 descends to the extinguishing position, the wick vertical shaft 14 is rotated clockwise, and this rotation of the wick vertical shaft 14 causes the rotation plate 23 to rotate.
Through this, the latch shaft movable body 27 and the latch shaft 29 return to their pre-ignition positions, and the latch 33 also returns to the state shown in FIG.

(In the case of emergency firefighting) When vibrations such as an earthquake are transmitted to the exterior case 1, the weight 38 of the seismic device 35 swings, and the operating rod 40 pulls up the disc 41, and the free end 36 of the locking plate 36 ' by moving the locking shaft 37 and the locking claw part 3 of the latch 33 upward.
3', the lamp wick 11 suddenly descends from the combustion position to the extinguishing position to extinguish the fire in the same manner as when extinguishing a normal fire.

As described above, whether the extinguishing lever 50 is activated to perform normal extinguishing, or the seismic device 35 is activated to perform emergency extinguishing, the wick 11 is powered by the wick lowering spring 21 for automatic extinguishing. The elastic force is used to lower the fire and extinguish the fire.

By the way, when a combustion device is used for a long period of time, or when oil that has deteriorated due to long-term storage is used, carbon accumulates on the wick 11 that protrudes into the combustion tube 4, and this carbon gradually As the wick 11 hardens, the thickness of the wick 11 increases at that part, and the elastic force of the wick lowering spring 21 does not allow the wick to fall into the space between the wick frame 10 and the air cylinder 9, resulting in the problem described in section (b). will occur. In this case, when the operating body 55 on the back of the exterior case 1 is pushed down in the direction of arrow C in FIG. The wick vertical shaft 14 is rotated clockwise as the lamp 11 is rotated, and the wick 11 is moved to the wick lowering lever 52.
can be lowered by applying force to

However, if an attempt is made to rotate the core vertical shaft 14 clockwise using the core lowering lever 52 while the locking pawl 33' of the latch 33 remains engaged with the locking shaft 37 of the locking plate 36, As the core vertical shaft 14 rotates, a force is applied to the latch shaft movable body 27 and the latch shaft 29 via the rotation plate 23 in the direction opposite to the arrow B in FIG. 33' and the locking shaft 37 may be destroyed. Therefore, in the device of the present invention, when the core lowering lever 52 begins to rotate, the sixth
As shown in the figure and FIG. 7, the release plate 59 rotates,
The lifting portion 61 moves the free end 36' side of the locking plate 36 upward in advance of the rotation of the core vertical shaft 14,
After the engagement between the locking shaft 37 and the locking claw portion 33' is released, the core vertical shaft 14 can be rotated by the core lowering lever 52. Therefore, latch 3
3 and the locking plate 37 are not likely to be damaged.

Incidentally, if the lamp wick 11 becomes hard to fall due to hardening of carbon, it may be replaced or the carbon may be removed by dry firing.

(F) Effects of the Invention Since the wick up-and-down type combustion device of the present invention is configured as described above, it is possible to solve the conventional problems and provide a highly safe device, and also to avoid accidental damage to the locking body or locking plate. It does not damage the locking means such as the above.
