The second protrusion (60b) protruding to be configured to operate the limit switch 40 fixed to the gas control valve body (10).

Such a conventional gas valve device is complicated by the structure of the push guide 60 is manufactured by precision casting by die casting (die casting), so not only the end of the manufacturing cost increases, but also the assembly process according to the use of many parts This complicated and time-consuming problem has arisen.

In addition, since the first protrusion 60a protruding to the other side lower portion of the guide 60 is formed at a considerable distance from the rotation shaft 11 which is a push point, the guide 60 is pressed in an unbalanced state. As a result, not only could not press the operation pin 24 accurately, but also abrasion occurred due to piece wear and the occurrence of jamming and malfunction of the components during the pressing operation.

In addition, since the push guide 60 was built in the case of the gas range, the overall thickness of the gas range could not be reduced, and thus, the push guide 60 was a critical obstacle to the slimming of the gas range.

Of course, when the upper plate of the gas range is metal, it is possible to perform sheet metal processing to protrude around the rotating shaft, but recently, when the upper plate of the gas range is formed of glass, it was not possible to form a thin thickness of the entire gas range.

The present invention has been made in view of the above problems, and an object thereof is to provide a lever and an ignition limit switch for pressing an operation pin of a safety valve body by a cylindrical operation tube of a simple structure coupled to a vertical rotation shaft of a gas control valve body.

The lever 20b is sealed by the elastic force of the spring 22a, and the operation pin 24 is coupled to the front of the valve 22 through a hinge 31 coupled to the gas control valve body 10. Pressing the valve 22 while being moved backward by the 30, the gas control valve body 10 has a limit switch 40 is high In the gas valve device (1) configured to supply a gas to the burner, the safety valve body 20 is provided with a gas outlet (23), the vertical axis of rotation of the gas control valve body 10 Cylindrical operating tube 50 is coupled to the elevating (11), the lower portion of the operating tube 50 is formed with an outward flange 51, the guide piece 30a protruding inward from the lever 30 is a flange ( It is located in the lower part of the 51 and pressed, an extension piece 41a bent inwardly is formed at the tip of the operating piece 41 of the limit switch 40 so as to be located and be pressed in the lower part of the flange 51. It can be achieved by a gas valve device for a gas range characterized in that.

Hereinafter, described in detail by the accompanying drawings a preferred embodiment for achieving the above object is as follows.

3 to 7B, the safety valve body 20 is coupled to the gas control valve body 10 at a right angle so that the gas flow passages 10a and 20a therein communicate with each other.

The rotary shaft 11 is vertically coupled to the gas control valve body 10, and when the knob 11a coupled to the upper portion of the rotary shaft 11 is rotated, the rotary body 12 is coupled to the lower portion of the rotary shaft 11. Is rotated inside the gas control valve body (10).

The rotating body 12 is formed with a guide groove 12a, and when the rotating body 12 is rotated, the guide groove 12a opens the flow path 10a so that the gas introduced through the gas inlet 13 is safe. It is supplied to the flow path 20a of the valve body 20.

By appropriately adjusting the opening degree of the guide groove 12a while rotating the rotor 12, the amount of gas supplied is adjusted to adjust the flame intensity of the burner (not shown).

The electromagnet 21 is coupled to the inside of the safety valve body 20, the electromagnet 21 is connected to a thermocouple (not shown) and wires mounted on the burner, the electromotive force generated when the thermocouple is heated By this, the electromagnet 21 is operated.

The metal rod 21a penetrates and is inserted into the electromagnet 21, and a valve 22 is fixed to the tip of the metal rod 21a, and the valve 22 is provided with gas flow passages 10a and 20a. The distribution hole 20b communicating with the spring 22a can be sealed by the elastic force of the spring 22a.

An actuating pin 24 is coupled to the front of the valve 22 through the actuating pin 24. The actuating pin 24 is pressed by the lever 30 coupled to the hinge 31 to the gas regulating valve body 10 and moved rearward. It is configured to press the valve 22.

A limit switch 40 is fixed to the gas control valve body 10, and the limit switch 40 applies a signal to ignite the burner.

According to the present invention having the above-described configuration, since the operation pipe 50 having a simple structure directly presses the extension piece 41a of the lever 30 and the limit switch 40, the number of parts is reduced as compared with the related art. This easy and cost-effective manufacturing of the overall valve device can be maintained at a low cost, and the operating pipe 50 is pushed by the lever 30 and the limit switch 40 at a minimum distance from the rotary shaft 11, which is a push point. Since the lever 30 is stably pressed while the balance of the balance is maintained, there is an advantage such that the operation pin 24 can be accurately pressed. Various problems such as phenomenon and malfunction are completely solved, which can maximize the external competitiveness of gas valve device.

In addition, since there is no need to use the guide 60 having a considerable height as in the prior art, the overall height of the valve device is formed to be low, and thus there is an advantage such that a slim gas range can be realized.

Meanwhile, when the lever 30 and the limit switch 40 are pressed while the operation pipe 50 is lowered by pressing the knob 11a coupled to the rotary shaft 11, the operation pin 24 is moved backward and the valve ( 22, the flow hole 20b blocked by the valve 22 is opened as the gas is pushed in so that the gas introduced through the gas inlet 13 opens the flow passages 10a and 20a and the outlet 23.
