Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to an oil-burning appliance using a 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. When adjusting the amount of combustion, the user moves the wick up and down, but in doing so, the user lowers the wick too much and restricts the amount of combustion too much, resulting in incomplete combustion and the generation of CO, etc., which are harmful to the human body. However, the safety of a combustion appliance that releases combustion gas indoors seemed to be a step further, as there was a risk of harming the user's health.

Purpose of the Invention The present invention has been made in view of the above points, and is aimed at improving safety.

Structure of the Invention In order to achieve the above-mentioned object, the present invention has a core that can freely move up and down, a rotary shaft that moves the core up and down by manual operation of a rotary knob, and a raised position based on the vertical movement of the rotary shaft. a spring means for accumulating a biasing force for lowering the wick to the extinguishing position; a ratchet wheel rotatably provided on the rotating shaft; and one end of the ratchet wheel is engaged with a pawl of the ratchet wheel to lower the wick to the extinguishing position. a swingable lock mechanism that locks the rotary shaft from rotating in the same direction as the rotational direction of the rotary shaft during descent; and a swingable lock mechanism that is provided between the rotary shaft and the ratchet wheel to prevent the rotary shaft from rotating in the direction in which the rotary shaft rotates on its center. is transmitted to the ratchet wheel, and when the ratchet wheel is locked, the rotary shaft can be rotated in the core lowering direction by operating the rotary knob to adjust the height of the wick and extinguish the fire, and when the ratchet wheel is unlocked, the fire is extinguished. Therefore, a linkage mechanism that allows the ratchet wheel and the rotary shaft to rotate in the core lowering direction by the biasing force of the spring means, and a linkage mechanism that allows rotation of the rotary shaft in the core lowering direction when the ratchet wheel is in the locked state within a certain range within the combustion range. It is equipped with a center height regulation mechanism that regulates the center height.

Effects According to the present invention, when the lamp wick is lowered from the combustion state by the above-described structure, it stops midway. Therefore, there is no chance of the user inadvertently lowering the wick too far, which would cause a rash.

Embodiment An embodiment of the present invention will be described below with reference to the accompanying drawings. In Figures 1 to 8, 1 is an oil tank, 2 is a vent pipe installed vertically in the center of the oil tank 1, 3 is a fire pan installed above the vent pipe 2, and 4 is installed above the oil tank 1. 5 is a grate tube provided above the outer tube 4; 6 is a lamp wick guided by the ventilation tube 2, the outer tube 4 and the grate tubes 3 and 5 and constantly biased in the downward direction; 7 is a rotating Reference numerals 11 and 12 are bearing members for the rotating shaft 7. The rotating shaft 11 and 12 move the lamp wick up and down via the rack 9 and pinion 10 by operating the knob 8. 1
3 is a plate spring 14, 14 (shown as an example of a linkage mechanism) on a rotating shaft 7 located outside the oil tank 1.
It is a ratchet wheel attached through
4 and 14, the rotation of the rotating shaft 7 becomes irrelevant. 15 a locking protrusion protruding beyond the pawl 13' of the ratchet wheel 13; 16 a long hole formed in an arc shape in the ratchet wheel 13; 17 an adjusting plate fixed to the rotating shaft 7; and 18 an adjusting plate 17. This is a pin that is attached and slides within the elongated hole 16. In this embodiment, the elongated hole 16, the adjusting plate 17, and the pin 18 form a center height regulating mechanism. Also 19
1 is a vibration sensing device mounted on the oil tank 1 via a mounting plate 20, and the substrate 21 is equipped with a vibration sensing section 22 made of a weight or the like. 23 is the substrate 21
A lever rotatably supported by a shaft 24,
One end is linked to the vibration sensing section 22, and the other end is protruding toward the ratchet wheel 13 and its tip is bent to form two forked locking pieces 25, 25. 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 constitutes a locking device 30 that locks with the ratchet wheel 13 and locks the lamp wick in the upwardly moved position. 31, the free end of the auxiliary lever 26 is always connected to the locking piece 2
a spring biased to abut against the inner surfaces of 5 and 25;
A spring 32 is interposed between the base plate 21 and the lever 23 and biased so that the locking piece 29 side of the auxiliary lever 26 is always in contact with the ratchet wheel 13. In this embodiment, the lever 23, the auxiliary lever 26, etc. form a locking mechanism. 33 is a fire extinguishing device that is provided separately from the rotating shaft 7 and can be rotated by a knob operation, etc.; it is attached to the base plate 21, and is connected to the lever 23 with a linear connecting body 34 with a slight slack; The lever 23 can be operated independently of the vibration sensing section 22 to release the auxiliary lever 26 from the ratchet wheel 13. Reference numeral 35 denotes a cushion device provided opposite the lower end of the rack 9, which comes into elastic contact with the rack and acts as a buffer when the wick is lowered.

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 can be adjusted within the range of the elongated hole 16 by rotating the knob 3 in the opposite direction. That is, in this combustion appliance, when the knob 8 is rotated in the opposite direction, the pin 18 of the adjustment plate 17 fixed to the rotating shaft 7 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.

On the other hand, if a shock is applied to the instrument during use due to an earthquake or the like, 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 13.
Therefore, since the lamp wick 6 is always urged in the downward direction, it instantly descends and is extinguished. In addition, the fire extinguishing operation during normal use is performed by the fire extinguishing device 33.
When the lever 23 is rotated to the left in FIG. 1, the lever 23 is pulled by the connecting body 34 and rotated in the same manner as when the vibration sensing device 19 is activated, thereby extinguishing the fire. When the fire is extinguished, the lower end of the rack 9 comes into elastic contact with the cushion device 35 and is cushioned.

Effects of the Invention As is clear from the above description of the embodiments, according to the present invention, the rotating shaft for moving the lamp wick up and down by the rotary knob can only be rotated within a certain range within the combustion range. It has great effects, such as reducing the temperature too much and using it in conditions that are unfavorable to the human body, such as eliminating the risk of injury and making it highly safe.
