Gas range valve for gas range

The present invention relates to a valve body for a gas range, and more particularly, to a valve body for a gas range, which controls the operation of a first latch valve and a second latch valve of a latch valve body by a control switch section provided at a rear end of a housing, To a valve body for a gas range which opens and closes a gas flow path of the valve body.

Generally, the gas range is a device for efficiently burning gaseous fuels to utilize heat and high temperature, and there are various types ranging from small-sized ones used for domestic winds to large-scale industrial burners used for boilers of thermal power plants do.

In recent years, a built-in gas range built in the lower part of the upper surface of a sink of a kitchen has also been released.

Particularly, such a gas range has a valve body, and the knob of the valve body is rotated in the forward direction or the reverse direction to adjust the discharge amount of the gas.

At this time, the discharge amount of the gas determines the heating time at which the cooking container containing the food is heated, in proportion to the size of the thermal power to be burned.

Patent Document 1 is related to a conventional gas valve switch cam assembly structure. Referring to this structure, a stopper portion which is horizontally moved inward is formed in a hollow shape with front and rear openings, and gas A shaft shaft which is slidably coupled to the inside of the valve body and presses the end of the valve body to press the valve body; a micro switch installed on one side of the valve body rear end; And a switch cam that is coupled to the other end of the shaft and rotates in the same direction as the shaft axis to operate the microswitch.

At this time, an ignition knob is provided at the rear end of the switch cam, and the ignition knob is pressed and rotated in one direction to press the shaft portion of the switch cam and press the stopper portion in the valve body.

In particular, the switch cam is integrally rotated by the rotation of the shaft shaft, so that the switch cam turns on the microswitch to output a high voltage to the spark module.

Then, the flow path connecting the gas inlet portion and the gas outlet portion in the valve body is opened, so that the gas supplied through the gas inlet portion is discharged to the gas outlet portion through the flow path.

However, in the above-described Patent Document 1, the supply of gas is simply controlled through the gas inflow portion and the gas discharge portion of the valve body, and the micro switch simply controls ON / OFF operation of the spark module, The latch valve can not be freely controlled by operating the ignition knob so that the latch valve is automatically controlled regardless of the intention of the user so that the cooking vessel heating time and / There is a problem that the heating rate can not be freely selected and controlled.
