An embodiment of the present invention will be described in detail with reference to the accompanying drawings.

1 is a plan view of an embodiment in which the present invention is applied to a gas range, and FIGS. 2 and 3 are planar cross-sectional views of the gas valve device of the present invention, and FIG. 4 is a cross-sectional view taken along line AA of FIG. FIG. 6 is a cross-sectional view taken along line BB, and FIG. 6 is a cross-sectional view taken along line CC of FIG. 3 showing the ignition operation of the gas valve device. FIG. 7 and FIG. As shown, reference numeral 1 denotes a gas range, reference numeral 2 denotes a gas valve device mounted on the front of the gas range 1, and reference numeral 3 denotes a timer device.

On the front of the gas valve device 2, the valve gear 4 and the rotary knob 5 are condensed in a state in which the valve shaft 21 protrudes long, and the valve gear is formed on the shaft of the timer device 3. A timer gear 31 engaged with (4) is installed. The valve gear 4 and the timer gear 31 are both pinions, and the valve gear 4 slides in a state where the valve gear 4 is engaged with the timer gear 31. It is configured to work.

The fixed pipe body 41 integrally coupled with the valve gear 4 is installed so as to be rotated separately from the valve shaft 21, and the fixed piece 42 fixed to the above-described working pipe body 41. And the valve shaft 21 is to be assembled in a state embedded in the rotary knob (5) assembled in two divided states, the rotational force of the rotary knob (5) operating body by the buried fixing piece (42) The valve gear 4 is configured to rotate when the rotary knob 5 is rotated because it is transmitted to 41.

The fixing piece 42 is satisfied if it is configured to transmit the rotational force of the rotary knob 5 to the working tube 41, so as to surround the entire outer circumference of the working tube 41 as shown in FIG. You may fix only to either side of a lower part.

An actuating pin 22 protruding to one side at the free end side of the valve shaft 21 causes the valve shaft 21 to also rotate when the rotary knob 5 is ignited and the rotary knob 5 is a timer. By the automatic start of the fire extinguishing operation by the valve shaft 21 is configured to be able to reverse rotation (rotation in the opposite direction when the ignition operation) to be closed.

The rotary knob (5) is elastically installed with a spring (6) with respect to the main body of the gas range (1), and also the rotary knob (5) itself while receiving the operating pin (22) inside the rotary knob (5) The rotating space 52 which can rotate the rotary knob 5 itself without being caught by the operation pin 22 while being in communication with the moving groove 51 and the inner end of the moving groove 51, which allows the holder to move forward and backward. ) Is formed.

Referring to the operation of the present invention configured as described above are as follows.

When the rotary knob 5 is not operated as shown in the example of FIG. 2, the rotary knob 5 is retracted from the main body of the gas range 1 due to the spring force of the spring 6. In the state in which the working pin 22 protruding in a fixed state on one side of the valve shaft 21 is located at the inner end of the moving groove 51 and coincides with the simultaneous rotation space 52.

In the state as described above, that is, while the gas range 1 is extinguished while the spring 6 pushes the rotary knob 5 elastically, the rotary knob 5 is fixed to the valve shaft 21. The moving pin 22 is moved away from the front of the gas range 1 until it is caught by the operating pin 22, whereby the operating pin 22 fixed to the valve shaft 21 of the rotary knob 5 The inner end of the moving groove 51 is in a state of being caught. Since the inner end of the moving groove 51 coincides with the start end of the rotation space 52, the rotary knob 5 is moved in the ignition direction ( When rotated in the counterclockwise direction in the drawing, since the rotation space 52 receives the operation pin 22, the valve shaft 21 cannot be rotated so that the ignition operation is not performed.

Therefore, to ignite the gas range (1) is to press the rotary knob (5) and then to ignite the operation. That is, when the rotary knob 5 is pressed as shown in FIG. 3, the rotary knob 5 moves toward the gas range 1 while compressing the spring 6 elastically and simultaneously coupled to the working body 41 at the same time. The valve gear 4 is slid in the timer gear 31. At this time, since the valve shaft 21 and the operation pin 22 fixed to the free end thereof are stopped, the valve 5 is turned off. When moving toward the range (1), since the moving groove 51 is in a straight line with respect to the operation pin 22 is to be able to press the rotary knob (5), the rotary knob (5) When pressed, the movable groove 51 receives the operation pin 22. In other words, the operating pin 22 is locked to the moving groove 51 out of the start end of the rotation space 52 is in a state capable of rotating with the rotary knob (5).

As described above, when the rotary knob 5 is pressed and rotated to the ignition position (counterclockwise in the drawing), the movable groove 51 rotates the operation pin 22. Accordingly, the valve shaft 21 ) Will also rotate. In the state in which the valve side 21 rotates, the gas flows out from the gas valve device 2 and when the valve shaft 21 rotates to the ignition position, it is ignited by the ignition device. Is the same as the existing gas range.

When rotating the rotary knob 5 for the ignition in the above, since the operating body 41 as well as the valve gear 4 is rotated state, the timer gear 31 is also rotated in the opposite direction to operate the timer device (3) It is a state to start.

As described above, when the ignition is performed by operating the rotary knob 5 to the ignition position, the force applied to the rotary knob 5 is removed. In this case, the rotary knob 5 by the elastic restoring force of the compressed spring 6 is applied. Is returned to its original state, and in the state where the rotary knob 5 is moved to its original position, the operating pin 22 is located at the start end of the rotation space 52 (see FIG. 7). In the state in which only the rotary knob 5 can be rotated counterclockwise, and when the rotary knob 5 is further rotated counterclockwise, the timer gear 31 rotates together in the direction in which the time is extended. (See Fig. 8).

Therefore, in order to prolong the combustion time in the state in which the rotary knob 5 is rotated to the ignition position, the counterclockwise until the desired ignition time is performed while the rotary knob 5 is not pressed (pulsed by a spring). Direction, in this case, the rotation space 52 accommodates the operation pin 22, so that the valve shaft 21 does not rotate, but only the rotary knob 5 rotates, and thus the valve gear 4 is rotated. Will extend the timer gear 31 to the desired time.

After the above operation is completed, since the timer device 3 starts to operate, the timer gear 31 operates the valve gear 4 while operating at a predetermined number of revolutions. Accordingly, the rotary knob 5 also rotates together. Until the end surface 52a of the rotation space 52 reaches the operation pin 22, only the rotary knob 5 is rotated in the fire extinguishing direction (clockwise in the drawing), and the end surface 52a is rotated. From the moment it touches the operation pin 22, the rotary knob 5 is in a state to rotate the valve shaft 21 by pushing the operation pin 22, so that the combustion flame is automatically extinguished at a set time.

As such, the present invention has the feature of automatically extinguishing a desired time after ignition of the gas range.

On the other hand, the present invention can be applied to gas valves, such as gas range, gas burner, etc., as well as to the intermediate valve installed in the gas pipe or gas hose for supplying gas can contribute to the prevention of safety accidents in gas use. .

According to the present invention as described above, a timer device is installed together with a gas valve device installed in a gas range, a gas burner, etc., so that the user can set the gas use time selectively so that it can be automatically extinguished after ignition. Not only does this prevent the boiling event, but it also prevents the combustion flames from being used while the gas is in use.This effect allows you to perform other tasks with confidence while using the gas. It is a very practical design that offers the advantages of having an effect.
