Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to an ignition device for a gas stove.

Conventional configuration and its problems Conventional rotary-type igniters for gas stoves require only a rotary operation, so the number of parts increases when trying to obtain the necessary functions, and the configuration required to operate the parts is complicated. However, problems arose in terms of quality, processing, and cost.

Purpose of the invention The purpose of this invention is to eliminate the above-mentioned conventional drawbacks, and to improve quality and ease of assembly by reducing the number of parts and simplifying the configuration, and to provide a cheaper ignition device. do.

Composition of the Invention In order to achieve the above object, the ignition device for a gas stove according to the invention includes a main shaft, a pin inserted perpendicularly to the axial direction of the main shaft, and a cam having a recessed part in which the pin engages, and pushes the main shaft. During rotation, the pin engages with the recess in the cam to rotate the cam, and when the pushing force is removed, the pin disengages from the recess in the cam, causing the cam to return to its original position. This structure closes the ignition circuit, and has the effect of smooth cam movement and reliable ignition.

Description of examples An embodiment of the present invention will be described with reference to the drawings.

In FIGS. 1 and 2, 1 is a main shaft with an operating knob (not shown) attached to one end, 2 is a bearing whose one end is screwed to a panel and into which the main shaft 1 is inserted, 3
is a shaft spring supported by the main shaft 1 at one end and a bearing 2 at the other end; 4 is a pin fixed to the main shaft 1; 5 is a cam that rotates to push in the push button 7 of the micro switch 6; A cam spring with the other end of the cam 5 inserted into the bearing 2; 9 a stopper for regulating the rotation angle of the main shaft 1; 10 a center shaft interlocking with the main shaft 1; and 11 a closure for controlling the amount of gas.

The operation of the above configuration will be explained below.

First, by pushing in the main shaft 1, the shaft spring 3 is compressed, the pin 4 is engaged with the recess 12 of the cam 5, and the center shaft 10, which is engaged with one end of the main shaft 1, is fitted into the closure 11. Next, when the cam 5 is rotated while still being pushed in (Fig. 3), the cam 5 is moved to the pin 4.
The cam spring 8 is compressed and the tapered surface 13 of the cam 5 presses the push button 7 of the micro switch 6 to open the ignition circuit (not shown), and the closing element 11 is also rotated. and rotates to open a gas circuit and ignite a burner (not shown).

Next, when the pushing force of main shaft 1 is removed (Fig. 4)
At the same time, the main shaft 1 returns to its original position due to the repulsive force of the compressed shaft spring 3, and the pin 4 is removed from the recess 12 of the cam 5, and the cam 5 is instantly moved due to the repulsive force of the compressed cam spring 8. It rotates and returns to its original position to close the push button 7 of the micro switch 6.

In this way, according to this embodiment, by the operation of one cam and two springs inserted into the main shaft,
The ignition circuit can be opened and closed reliably, with a small number of parts,
This has the effect that it can be made into a simple structure.

Effects of the invention As described above, according to the invention, it is possible to obtain an ignition device that has a simple structure with a reasonably small number of parts, and has the effects of smooth cam movement and reliable ignition. It is something.

Claims (1)

[Scope of utility model registration request] A closure that opens and closes a gas passage by rotating, a center shaft that engages and rotates the closure, a main shaft that rotates the center shaft, and a pin inserted in a direction perpendicular to the axial direction of the main shaft. , a cam that engages with the pin and rotates in the rotational direction of the main shaft to open and close the ignition circuit; a cam spring that acts in a direction opposite to the rotational direction of the cam; and a cam that pushes the main shaft. The cam is equipped with a cam spring that acts in the opposite direction to the operating direction, and by pushing and rotating the main shaft, the cam is connected to the pin and rotates, which connects the switch that opens and closes the ignition circuit to the burner. When the ignition is ignited and the pushing force of the main shaft is removed, the shaft spring moves the main shaft in a direction opposite to the pushing operation direction, so that the pin is disengaged from the engaging portion of the cam, and the cam spring A gas-fired ignition system in which the cam is returned to its pre-rotation position and the switch that opens and closes the ignition circuit is closed.
