Abstract

PURPOSE:To simplify operation of a gas burner, by making locking or releasing of a heat power adjusting lever by only turning operation of an ignition knob. CONSTITUTION:When an ignition knob 3 is turned in the direction of (a), gas is entered into a burner 15 by passing through a gas outlet 12 and the title burner is ignited by an ignition electrode. A return layer 10 is turned in the direction of the (a) through turning of the ignition knob 3, a lock lever 8 is turned in the direction of (b) centering around a fulcrum 8a and the lock is released by the top 8b of the lock lever 8 by breaking away from a lock part 7a of a heat power adjusting lever 7. The heat power adjusting lever 7, therefore, becomes rotatable centering around a turning fulcrum 7b and combustion of a gas burner 15 can be made into weak combustion by turning the heat power adjusting lever 7 in the direction of (c). To extinguish the title burner the ignition knob 3 is returned in the reverse direction of the (a). When the ignition knob 3 arrives at a stop position, the heat power adjusting lever 7 is locked by the lock lever 8 and the title burner is extinguished at the most strong position of heat power.

Description

[Detailed Description of the Invention] [Object of the Invention] The present invention relates to a gas control device for a gas combustor used in general households. The structure was such that the child could be rotated while pushing the eldest child and the lock could not be removed, so there was an inconvenience that two movements of pushing and turning were required to release the lock.However, the present invention eliminates this inconvenience by only turning the lock. The goal is to make the gas control device convenient to use by having a structure that can be unlocked at the same time.

[Structure of the Invention] The gas control device for a gas combustor of the present invention includes a rotary ignition knob, a gas cock incorporating a safety valve and an igniter that interlocks with the ignition's heir shaft, and a return lever that interlocks with the heir shaft. , a lock lever whose lower end contacts the circular arc arm of the return lever and rotates around a fulcrum; a firepower adjustment lever which engages with and separates from the upper end of the lock lever;
The gas pressure variable device is similar to a gas pressure variable device in which gas pressure is adjusted by a return spring that biases the fire power adjustment lever in a direction in which the lock lever locks, and a linear lever that interlocks with the fire power adjustment lever. The device is characterized in that the gas pressure is strong when the ignition is in the ignition stop position, and the gas pressure can be adjusted only when the ignition is in the open position. shall be.

Embodiments of the present invention will be described with reference to the drawings. 1 is a gas inlet, 2 is a gas cock containing an igniter, a safety valve, etc., 6 is a rotary ignition knob, 4 is a gas pressure variable device, and 5 is a rotatable cylindrical portion. 6 is a linear lever that drives the cylindrical portion 5 of the variable gas pressure device 4, and is interlocked with the firepower adjustment lever 7. Reference numeral 8 denotes a lock lever whose upper end engages and disengages from the lock portion 7α of the firing power adjustment lever 7, and whose lower end slides into contact with the circular arc arm 10α of the return lever 10 that interlocks with the ignition heir shaft 11. 9
is a return spring that biases the lock lever 8 in the direction in which the fire power adjustment lever 7 is locked. 12 is a gas outlet (to a burner) 1!1 is an ignition electrode, 14 is a thermocouple, and 15 is a burner.

Next, its effect will be explained. In the above structure, when the ignition head 3 is rotated in the direction of the arrow α, the safety valve in the gas cock 2 opens, and gas passes from the gas inlet to the gas outlet 12 and enters the gas burner 15. At this time, a spark is generated in the ignition electrode 13 by the igniter in the gas cock 2, and the gas is ignited. A thermoelectromotive force is generated in the thermocouple 14 by the combustion heat of the gas burner 15, and the safety valve in the gas cock 2 is kept open. After that, combustion will continue even if the power is turned off 30 times.

When the return lever 10, which rotates in conjunction with the ignition heir shaft 11, rotates in the direction of the arrow α as the ignition heir 5 rotates, the lock lever 8 whose lower end abuts the return lever 100 and the circular arc arm 10α becomes a fulcrum. It rotates about 8α in the direction of the arrow (FIG. 1), and its upper end 8h disengages from the lock portion 7a of the firepower adjustment lever 7 to unlock the firepower adjustment lever 7. Therefore, the firepower adjustment lever 7 is rotatable about the pivot point 7b.

In this state, when the rear end 7C of the firepower adjustment lever 7 is rotated in the direction of arrow C (FIG. 2), the linear lever 6 is rotated in the direction of arrow d about the fulcrum 6α, and the cylinder of the gas pressure variable device 4 is rotated. The gas pressure is adjusted by moving the shaped part 5 in the direction of arrow e and making the pressure of the back pressure spring variable. In short, by rotating the heating power adjustment lever 7 in the direction of arrow C, the combustion of the gas burner 15 can be made weak.

As described above, when the ignition heir 3 is rotated to the left (in the α direction), the fire power adjustment lever 7 is unlocked and can be slid freely, thereby adjusting the combustion amount of the gas burner 15. is free. Next, when extinguishing the gas burner 15 from a weak combustion state, return the ignition heir 3 in the opposite direction of the arrow α (closing direction), and the return lever 10 will interlock with this, and the spark adjustment lever 7 will move in the same way. The lock lever 8 slides in the direction (chord direction of the firepower), and the lock lever 8 returns to the spring 9.
The circular arc arm descends along 5-10α. When the igniter 3 reaches the stop position, the fire power adjustment lever 7 is locked by the lock lever 8, and the fire is extinguished at the nodal position of the fire power.

[Effects of the Invention] Since the present invention has the above structure and operation, it has the following effects.

(1) The firepower adjustment lever can be locked and released simply by turning the ignition heir, and the amount of gas burned can be freely adjusted. Because it is in a nodal position, there are fewer ignition errors, and the thermocouple rises quickly, making the burner combustion stable quickly.

(3) With gas cocks that supply gas by simply turning the cock, there is a risk of raw gas leaking out if the cock does not ignite, and this is especially dangerous when the firepower adjustment lever is turned. However, in the present invention, the fire power adjustment lever cannot be rotated unless the ignition heir is rotated, so the gas cannot be supplied by the fire power adjustment lever, so gas leakage without ignition is prevented. It's safe.
