Description

[Detailed Description of the Invention] [Technical Field of the Invention] This invention relates to a wick operating mechanism applied to a combustion stove with an upper and lower wick type.

[Technical background of the invention and its problems]

In the wick up-and-down type combustion method, a cylindrical wick whose lower end is permanently immersed in liquid fuel such as kerosene is raised when fuel starts to protrude into the fire pan, and the upper end of the cylindrical wick is ignited for combustion. The combustion power is adjusted by moving the wick up and down over a width of several millimeters, and extinguishing is done by lowering the wick significantly.

As a mechanism for operating the lamp wick up and down in this way, a mechanism configured as shown in Fig. 1 has been known.
The wick can be moved up and down by rotating the lamp. A locking lever 2 is rotatably attached to the operating shaft 1, and an operating lever 3 is fixedly attached thereto. The locking lever 2 has a hook-shaped locking portion 4 at its free end.
and a receiving piece 5 on the lower edge thereof, and the lower edge of the operating lever 3 is in contact with the receiving piece 5. The locking lever 2 is biased counterclockwise in the figure by a spring 6, and an engaging pin 7 is provided protruding from the side surface of the free end of the operating lever 3. Reference numeral 10 denotes an adjustment lever, which is rotatably supported via a support pin 11 disposed approximately in the middle thereof, and an interlocking lever 12 is rotatably connected to one end. The support pin 11 is inserted into a horizontally long support hole 14 formed in the substrate 13, and a spring 15 is attached to the support pin 11, which causes the support pin 11 to move elastically in the right direction in the figure. is energized by An adjustment pin 16 is attached to the end of the interlocking lever 12, and this adjustment pin 16 is connected to the base plate 1.
It is fitted into a vertically elongated guide hole 17 formed in 3. An engagement groove 18 is formed at the other end of the adjustment lever 10, and an engagement groove 18 is formed at the upper edge.
An arc-shaped introduction part 19 is formed that continues to the side edge of the opening 8 . An ignition pin 20 is provided above the free end side of the operating lever 3, and this ignition pin 20 is connected to the base plate 13.
It is fitted into a vertically elongated engagement groove 21 formed in the .

Reference numeral 22 denotes an operating lever that is linked to the vibration sensing mechanism, and this operating lever 22 is provided with a locking pin 23 that can be freely engaged and detached from the locking portion 4 of the locking lever 2.

FIG. 1a shows a state in which combustion operation is on standby, and when the ignition pin 20 is lowered from this state, the ignition pin 20 presses the operating lever 3.
rotates clockwise in the figure together with the operating shaft 1. In response to this rotation, the engagement pin 7 first comes into contact with the introduction part 19, and is guided by the introduction part 19 into the engagement groove 18.
enters and engages. At this time, the adjustment lever 10 is slightly displaced to the left in the figure together with the support pin 11 against the spring 15, and the engagement pin 7 is moved to the introduction part 1.
After passing through 9, it returns to its original position. Then, due to the engagement between the engagement pin 7 and the engagement groove 18, the first
As shown in Figure b, the operating lever 3 is connected to the adjusting lever 10.
Connect to. Further, the rotational movement of the operating lever 3 is transmitted to the locking lever 2 via the receiving piece 5, and the locking lever 2 rotates clockwise in the figure against the spring 6, and the locking portion 4 is the operating lever 2
It engages with the second locking pin 23. Then, by rotating the operating shaft 1, the wick rises to the combustible range, and its upper end protrudes into the fire pan.In this state, the upper end is ignited to start combustion.

When the adjustment pin 16 is operated up or down in this state where combustion has started, the movement is transmitted to the adjustment lever 10 via the interlocking lever 12, and this adjustment lever 10 rotates around the support pin 11. This rotation causes the operating lever 3 to rotate, and the rotation of the operating shaft 1 causes the wick to move up and down within a range of several millimeters within the combustible range, thereby adjusting the combustion power. .

On the other hand, when the vibration sensing mechanism is activated or when the manual fire extinguishing lever (not shown) is operated, the operating lever 22 is rotated and the locking pin 23 is disengaged from the locking portion 4 of the locking lever 2. In response, the locking lever 2 is rotated counterclockwise in the figure together with the operating lever 3 by the biasing force of the spring 6, and as a result, the lamp wick is greatly lowered from the combustible area and extinguishing is achieved.

However, in such a configuration, at least the locking lever 2, the operating lever 3, and the adjusting lever 10
These three components are required as a minimum, which makes the configuration complicated, troublesome to assemble, and high cost.Also, when adjusting the wick up or down in the combustible range, the adjustment range can be adjusted by the rotation range of the adjustment lever 10. However, due to errors in the installation of the adjustment lever, the adjustment width may vary, causing the lamp wick to be misaligned, which can lead to abnormal combustion.
