Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention relates to a wick operating mechanism for a wick-type combustion device configured as a stove or the like.

[Technical background of the invention and its problems] A wick-type combustion device continues combustion through a wick.In other words, a cylindrical wick braided with fibers, etc. can be raised and lowered around the outer periphery of a wick guide tube. The lower end of the wick is constantly immersed in liquid fuel such as kerosene. During combustion operation, the wick is raised so that its upper end faces the fire pan, that is, located in the combustible area, and at that position the upper end of the wick is ignited to continue combustion. The combustion power is adjusted by moving the wick up and down above the fire pan, and extinguishing is done by lowering the wick below the fire pan. There is also one in which the combustion power is adjusted, that is, the wick is raised and lowered by rotating a lever.

By the way, as long as the wick moves up and down within a certain range, the state will be maintained properly regardless of whether the combustion is strong or weak, but in the past, the wick would often accidentally move out of that range. As a result, there were many problems such as abnormal combustion, creating a risk of monoxide poisoning, and a large amount of tar adhering to the wick, impairing its function.

[Purpose of invention]

This idea was developed with this in mind, and its purpose is to ensure that the lifting range of the lamp wick is always within a certain range, thereby reliably preventing the occurrence of improper combustion. An object of the present invention is to provide a wick operating mechanism for a combustion device.

[Summary of the idea]

In other words, this invention consists of a locking lever that raises and locks the wick, which can be raised and lowered, against the urging force of a spring to the combustible range, an operating lever that moves the raised wick up and down in conjunction with the lever, and A regulation mechanism that regulates the rotation range of the lever to a certain level, and a release mechanism that releases the regulation of this regulation mechanism and rotates the operating lever with the biasing force of a spring to lower the wick to an extinguishing position below the combustible range. The system is equipped with the following.

A pendulum shaft 76 is attached to the lower end of the seismic pendulum 71 passing through the clutch lever 72 and the base 70, and a disk 77 is formed at the lower end of the pendulum shaft 76. A portion of the peripheral edge of the disc 77 comes into contact with the clutch lever 72 in response to the tilting of the seismic pendulum 71, so that the clutch lever 72 rotates clockwise against the spring 74. A forced fire extinguishing lever 78 is provided on the front surface of the board 13, and this forced fire extinguishing lever 78 is rotatably supported via a pin 73 and elastically biased counterclockwise by a spring 80. . A bent piece 81 is formed on the forced extinguishing lever 78, and this bent piece 81 protrudes through the opening 82 of the base plate 13 to the rear side thereof, and is disposed so as to face one end of the clutch lever 72. Note that 83 is an operation knob for the forced extinguishing lever 78.

Next, the operation will be explained. When the ignition slider 47 and the adjustment slider 46 are pulled down along the sliding groove 45 from the state shown in FIG. 2, the ignition lever 18 and the operating lever 19 are rotated clockwise in conjunction with this. At this time, since the operating lever 19 presses the bent piece 35 of the locking lever 21, the locking lever 21 also rotates clockwise together with the operating lever 19 against the spring 37. The lower end of 19 is the regulating piece 29 of the release lever 20.
In order to press , the release lever 20 also rotates integrally. Then, as the locking lever 21 rotates, the clutch plate 38 at the other end is moved to the clutch lever 72.
The locking portion 39 engages with the locking pin 75, thereby preventing the locking lever 21 from rotating in the counterclockwise direction. The operating lever 19 is integrally connected to the operating shaft 6 via the support tube 15. Therefore, as the operating lever 19 rotates, the operating shaft 6 also rotates clockwise, causing the interlocking fitting 7 to rotate. Through this, the wick 4 is pushed up above the fire pan 3, and its upper end rises to the upper limit position of the combustible range. Further, when the ignition lever 18 is rotated, an ignition mechanism (not shown) operates in conjunction with the rotation of the ignition lever 18, and the above-mentioned lamp wick 4
The ignition lever 18 is then ignited by releasing the pull down on the ignition slider 47.
is rotated counterclockwise by the biasing force of the spring 22 and returns to its original position. When the wick 4 is ignited, the liquid fuel in the oil tank 1 is sucked up into the wick 4 and vaporized one after another, and combustion continues with this vaporized gas.

By the way, when the ignition slider 47 and the adjustment slider 46 are pulled down, the press pin 24 of the ignition lever 18 comes into contact with the side edge of the first regulating metal fitting 60 in the middle, and accordingly, the first regulating metal fitting 60 is pulled down. rotates counterclockwise against the spring 64, and as a result, the second regulating metal fitting 62 moves against the adjustment slider 46.
Displaced to the placement side. Then, the protrusion 54 of the adjustment slider 46 comes into contact with the second regulating metal fitting 62, and accordingly, the second regulating metal fitting 62 rotates clockwise against the spring 65, and the protrusion 54 contacts the second regulating metal fitting 62. passes through the placement part and reaches below it. Here, the adjusting slider 46 is not pulled down enough, and the adjusting slider 46 is not pulled down enough before the locking portion 39 of the clutch plate 38 engages with the locking pin 75 of the clutch lever 72.
When the lowering of the adjustment slider 46 is released, the protrusion 54 of the adjustment slider 46 comes into contact with the second restriction fitting 62 and is temporarily blocked from rising, and the ignition slider 47
is raised and the first regulating fitting 60 is rotated clockwise, so that the second regulating fitting 62 is retracted from that part, and then the adjustment slider 46 is raised with a delay in the movement of the ignition slider 47.

When the adjustment slider 46 is pulled down as specified to start combustion, strong combustion continues because the wick 4 is held at the upper limit position of the combustible range as described above. If the combustion power is to be adjusted from this state to medium combustion or weak combustion, the adjustment slider 46 is moved up and down. That is, the operating lever 19 is connected to the regulating pieces 28, 2 on the release lever 20.
By operating the adjustment slider 46 to position the operating lever 19 in the middle, the lamp wick 4 can be held in the middle position of the combustible range to achieve medium combustion. Similarly, by positioning the operating lever 19 at the upper end, it is possible to hold the wick 4 at the lower limit position of the combustible range and set the firepower for weak combustion. The lifting range of the lamp wick 4 that operates in this manner is always precisely regulated by the regulating pieces 28 and 29, so that proper combustion is always maintained.

On the other hand, when performing normal fire extinguishing, the adjustment slider 46 is pushed up further above the firepower adjustment range by applying a certain force. In response, the operating lever 19 contacts and presses the regulating piece 28 of the release lever 20, and this pressing force causes the locking pin 42 that engages with the hook 31 to move along the elongated hole 41 against the spring 43. As a result, the engagement between the locking pin 42 and the hook 31 is released, and as a result of this release, the operating lever 19 is rotated counterclockwise by the biasing force of the spring 40, and the locking piece 34 of the locking lever 21 is rotated. It stops when it comes into contact with it. At this time, the regulating piece 29 of the release lever 20 collides with the lower edge of the operating lever 19, but since an elastic body 30 is attached to the upper surface of this regulating piece 29, this elastic body 30 prevents the The impact is alleviated and the impact noise is kept low. Also,
If the engagement between the hook 31 and the locking pin 42 is too strong, it will be difficult to release the engagement, and if it is too weak, the engagement will be inadvertently released due to impact, etc. The setting of the strength of the spring 43 is an important requirement, but it can be easily satisfied by appropriately selecting the strength of the spring 43, that is, the number of turns and wire diameter. This operation causes the wick 4 to
is pulled down below the combustible area, that is, below the fire pan 3, thereby achieving extinguishment. In such a case of extinguishing the fire, the operating lever 19 comes into contact with the restraining piece 34 and its rotation amount is restricted, so the wick 4 is held at a shallow position below the fire pan 3, and therefore the extinguishing time is prolonged to some extent. However, it is possible to extinguish a fire with almost no odor.

Extinguishing the fire is achieved in this way, but for added safety, the forced extinguishing lever 78 is operated, for example, before going to bed. That is, the forced extinguishing lever 78 is rotated clockwise against the spring 80. Then, the bent piece 81 of the forced extinguishing lever 78 comes into contact with the clutch lever 72, and the clutch lever 72 rotates clockwise against the spring 74, thereby releasing the locking pin 7 of the clutch lever 72.
5 and the locking portion 39 of the locking lever 21 is released. With this release, the locking lever 21 rotates counterclockwise by the biasing force of the spring 37, and during this rotation, the bent piece 35 of the locking lever 21 comes into contact with the operating lever 19, and the locking pin 42 engages with the hook 31, and in this state, the whole unit further rotates counterclockwise, and the adjustment slider 46 comes into contact with the ignition slider 47, and the whole unit stops and returns to its original position, whereby the lamp wick 4 is pulled down deeply below the fire pan 3, ensuring safety. Since the operation lever 19 is previously arranged at an intermediate position and starts rotating from a position halfway through the rotation of the locking lever 21, the range of its rotation is small, so that the adjustment slider 46 does not touch the ignition slider 47. The impact when touching is small,
The impact noise can be suppressed to a low level. When operating the ignition slider 46 and adjustment slider 47,
The operation is performed by gripping the operation knobs 52 and 53, respectively, and although not shown in the drawings, a display indicating the range and position of the operation is provided on the side part of the sliding groove 45, and a predetermined operation is performed based on the display. Moreover, since the ignition slider 46 and the adjustment slider 47 are arranged in a straight line along the sliding groove 45, this operation can be easily performed.

On the other hand, if an earthquake or the like occurs while combustion continues, the seismic pendulum 71 tilts, and the clutch lever 72 rotates clockwise in response to this, and the locking pin 75 and locking portion The engagement with 39 is released. In this case, when the engagement is released, the locking lever 2 is moved by the urging force of the spring 37.
1 and the operating lever 19 are rotated in a counterclockwise direction integrally almost from the beginning, so that the lamp wick 4 is pulled down at once to a deep position below the fire pan 3, and emergency fire extinguishing is achieved.

The clutch plate 38 slides into and out of contact with the locking pin 75 of the clutch lever 72, and since the clutch plate 38 is made of synthetic resin,
The engagement and disengagement operations can always be performed smoothly with high precision without requiring processing such as grinding or polishing as is the case with metal materials.

It should be noted that this invention is not limited to the one embodiment described above, and it goes without saying that the configuration of each part can be modified in various ways without departing from the gist of the invention.

[Effects of the invention] As explained above, according to this invention, the lamp wick, which has been raised to the combustible range, is raised and lowered by rotating the control lever, and the rotation range of the control lever is kept constant by the regulating mechanism. Since the lamp wick is regulated within the range of 100 to 100, the vertical range of the lamp wick can be maintained appropriately, and proper and stable combustion can be maintained at all times, thereby making it possible to reliably prevent abnormal combustion from occurring.
