Description

[Detailed description of the invention] Industrial application field The present invention relates to an oil-burning appliance using a lamp wick.

Conventional Structure and Problems Conventionally, this type of oil-burning appliance has been designed to raise the wick to burn the lamp, and to extinguish the fire by lowering the wick to extinguish the fire. and the descent of the above-mentioned wick,
In other words, extinguishing the fire is done by rotating the wick adjustment knob. Therefore, each time the fire is extinguished, the wick adjustment knob must be manually turned and turned, making the fire extinguishing operation extremely troublesome. The amount of combustion can be adjusted by rotating the wick adjustment knob, but in doing so, the user may turn the wick adjustment knob too much and reduce the amount of combustion too much, resulting in incomplete combustion, which can be harmful to the human body. As a combustion appliance that emits combustion gas into the room, I felt that it was not safe enough, as it generated CO and other gases that could harm the user's health.

Purpose of the invention The present invention was made in view of the above points, and aims to extinguish fires with simple operations and at the same time improve safety.

Structure of the invention In order to achieve the above object, the present invention has a lamp wick that can be moved up and down, a rotation shaft that moves the lamp wick up and down by manual operation of a rotation knob, and a raised position based on the operation of moving the rotation shaft up and down the wick. a spring means for accumulating a biasing force for lowering the wick to the extinguishing position; a ratchet wheel rotatably provided with respect to the rotating shaft; and a ratchet wheel that engages with the ratchet wheel to rotate the rotating shaft when the wick is lowered. and a locking mechanism that locks rotation in the same direction as the rotating shaft. The rotation of the rotary shaft in the center-up direction is transmitted to the ratchet wheel, and when the ratchet wheel is in the locked state, the rotary shaft is allowed to rotate in the center-downward direction by operating the rotary knob, and when the ratchet wheel is unlocked, the ratchet wheel is rotated. and a linkage mechanism for achieving rotational return of the rotary shaft in the center-lowering direction and core-lowering, and a pin of the adjustment plate fixed to the rotary shaft and a long hole formed in the ratchet wheel with which this pin engages, to lock the ratchet wheel. a core height regulating mechanism that mechanically regulates the rotation of the rotary shaft in the core downward direction within a combustion range within a certain range; a vibration sensing device that senses vibrations and releases the lock of the ratchet wheel by the locking mechanism; Equipped with a manual operating body for releasing the lock by removing the locking mechanism from the ratchet wheel, it is possible to extinguish the fire using the manual operating body and a vibration sensing device, and to regulate the vertical movement of the core within a certain range using a rotary knob. It is something to do. With this configuration, the present invention can instantaneously lower the wick and extinguish the fire just by operating the manual operating body with one touch, similar to extinguishing using a vibration sensing device. The center can only be moved up and down within a certain range.

Reference numeral 9 denotes a vibration sensing device mounted on the oil tank 1 via a mounting plate 20, and its substrate 21 is equipped with a vibration sensing section 22 made of a weight or the like. 23 is the board 2
1 is rotatably supported by a shaft 24, one end is connected to the vibration sensing section 22, and the other end extends toward the ratchet wheel 13, and its tip is bent to form a two-pronged locking piece. 25, 25 are formed.

Reference numeral 26 denotes an auxiliary lever rotatably supported by a shaft 27 on the ratchet wheel 13 side of the lever 23. This has a window 28 formed in its center, and is bent downward at the window edge on the free end side of the lever. A locking piece 29 is provided. The auxiliary lever 26 and the ratchet wheel 13 constitute a locking device 30 that locks the lamp wick 6 in the ascending position. Reference numeral 31 is a spring that urges the free end of the auxiliary lever 26 to always come into contact with the inner surface of the locking pieces 25, 25; 32 is a spring that is interposed between the base plate 21 and the lever 23, and This spring is biased so that the 29 side always comes into contact with the ratchet wheel 13. Note that the lever 23, the auxiliary lever 26, and the springs 31, 3
The second element forms a locking mechanism. Reference numeral 33 denotes a manual fire extinguishing operation body that is provided separately from the rotating shaft 7 and rotated by a knob operation, etc. It is attached to the base plate 21 and connected to the lever 23 by a connecting body 34, and is connected to the vibration sensing section 22. The auxiliary lever 26 can be released from the ratchet wheel 13 by operating the lever 23 regardless of the position.

When the knob 8 is operated in the oil burning appliance described above, the lamp wick 6 is raised by the action of the rack 9 and pinion 10, but at the same time the ratchet wheel 13 is also rotated. The ratchet wheel 13 has its peripheral edge located between the locking pieces 25, 25, and when rotating, each pawl 13' pulls the free end of the auxiliary lever 26 against the spring 31.
Rotate while pushing against the When the rotation is stopped, the pawl 13' moves to the locking piece 29 of the auxiliary lever 26.
is engaged, preventing reverse rotation and holding the ratchet wheel 13 in its position against bias. That is, the lamp wick 6 protrudes by a predetermined amount and the protruding height is maintained. When the ratchet wheel 13 is rotated, the auxiliary lever 26 rotates about the shaft 27, but the lever 23 does not move at all due to the force relationship between the springs 31 and 32. Further, the maximum amount of protrusion of the lamp wick 6 is regulated by the engagement of the locking protrusion 15 with the free end of the auxiliary lever 26.

Next, the protruding height of the lamp wick 6, ie, the combustion amount, can be adjusted within the range of the elongated hole 16 by rotating the knob 8 in the opposite direction. That is, in this combustion appliance, when the knob 8 is rotated in the opposite direction, the adjustment plate 17 fixed to the rotating shaft 7
The pin 18 engages with the edge of the elongated hole 16, and further rotation is prevented. Therefore, when the user adjusts the combustion amount by rotating the knob 8 in the opposite direction, the adjustment is limited to a certain range.

Next, if a shock is applied to the instrument due to an earthquake or the like during use, the vibration sensing section 22 senses this and rotates the lever 23 about the shaft 24 against the spring 32 in the direction of the arrow in FIG. As a result, the lever 23 also moves the auxiliary lever 26 in the same direction via the locking pieces 25, 25, and releases the lock from the ratchet wheel 15. Therefore, since the lamp wick 6 is always urged in the downward direction, it instantly descends and is extinguished.

In addition, when the fire extinguishing operation is performed, when the manual fire extinguishing operation body 33 is rotated to the left in FIG.
4, it rotates and extinguishes the fire.
Although it is not necessary to further rotate the knob 8 in the wick downward direction when extinguishing the fire, in this case the locking protrusion 15 engages with the locking piece 29 of the auxiliary lever 26, which may cause problems during the next use. There isn't.

Next, an embodiment of the above-mentioned manual fire extinguishing operation body 33 will be described with reference to FIGS. 8 to 10. Compared to the one shown in FIG. 1, the one shown in FIG. 8 has a long hole 35 in the base plate 21, which guides the protruding piece 37 of the operating part 36 and restricts its rotation. They are different in that they are and connector 3
4 is provided between the operating portion 36 and the auxiliary lever 26 side of the shaft 24 of the lever 23. The connecting body 34 only needs to be flexible and relatively light, but the connecting body 34 shown in FIGS. 1 and 8 uses a chain link. The one shown in FIG. 9 omits the connecting body 34 compared to the one shown in FIG.
8 in that the vibration sensing portion 22 side is directly pushed up from the shaft 24 of the lever 23 using the operating piece 39 of the lever 23. The device shown in FIG. 10 is different from the device shown in FIG. 1 in that the vibration sensing section 22 is directly operated by an operating lever 40 that moves back and forth. Note that the tip of the operating rod 40 may be formed into a ring so as to surround the vibration sensing section 22.

The manual fire extinguishing operation bodies 33 shown in FIGS. 8 to 10 described above are all for extinguishing a fire, and the rotating operation direction is reversed, or the rotating operation is performed back and forth. However, there is no difference in extinguishing a fire.

Note that the linking mechanism, center height regulating mechanism, locking mechanism, etc. described in the above embodiments are not limited to those described above.

Effects of the Invention As is clear from the description of the embodiments above, in the present invention, when vibrations occur due to an earthquake, etc., the vibrations are detected by a vibration sensing device and the lock mechanism is operated, and during normal fire extinguishing, a manual fire extinguisher is operated. The locking mechanism is operated by the operating body, and in both cases, the locking of the wick by the locking mechanism is released and the wick is rapidly lowered to extinguish the fire instantly, resulting in extremely high safety.

Moreover, the above-mentioned normal fire extinguishing can be done by lowering the wick and extinguishing the fire by simply slightly displacing the manual operating body without having to rotate the rotating shaft for raising and lowering the wick one by one, making the extinguishing operation extremely simple and quick. become.

Furthermore, even when a normal fire is extinguished, the wick is released from the locking mechanism and the fire is extinguished instantaneously, just as when vibration is detected. It can be confirmed that the system can be used reliably, and if there is a malfunction, it can be repaired immediately to ensure safety, and the user has a high sense of security regarding emergency fire extinguishing.

In addition, in this invention, the rotation of the lamp wick up and down rotation shaft by the rotation knob is mechanically stopped within a certain range within the combustion range, so the user can adjust the rotation while looking at the combustion amount adjustment display. Even if no special precautions are taken, the lamp wick is lowered too low and the lamp wick is no longer harmful to the human body when used in conditions that are not favorable to the human body, resulting in a highly safe product, which has great effects.
