Abstract

PURPOSE:To prevent the blow-out of flame just after ignition by a method wherein a high flame position made by the first operating member of a flow rate control valve is set to a forward position over the ignition position made by the second operating member. CONSTITUTION:The first operating member 4 changes over a flow rate control valve 3 from a low flame position where minimum volume of gas is fed to a high flame position where a maximum volume of gas is fed. The second operating member 6 advances the valve 3 to the ignition position C and at the same time operates a switch 5a placed in an operating circuit for the igniter unit 5. When the first operating member 4 is set at the rightward position shown in the figure, the flow rate control valve 3 has no pushing force and is placed at the low flame position and further when the second operating member 6 is operated under this condition, the valve 3 is pushed by this member and advances to occupy the ignition position and thus a superior ignition is applied to the burner 1. Then, when the first operating member 4 is moved in a leftward direction, the control valve 3 is pushed and advances more, resulting in occupying the high flame position B where the maximum volume of gas is fed, and even if the second operating member 6 is operated with this condition, the valve 3 has no pressing and advancement caused by the member 6 and then it is remained at the former high flame position B.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a gas control device for a gas stove or other gas combustor.

The applicant of this application has previously proposed a device of this type, for example, in the patent application filed in
As described in No. 8-145758, the flow rate control valve inserted in the gas passage leading to the gas burner is pushed by the first operation member, and the flow rate control valve is pushed from the rear low-fire position where the gas amount is minimum. The gas sensor in front of it can move freely to the maximum high flame position, and when the second operating member for controlling the point size is operated, it can be pushed by the second operating member to increase the amount of gas. However, in such a device, the ignition position may be located beyond the strong flame position and in front of it, and according to this, when the second operating member is operated to ignite, The control valve is further moved from the previously advanced strong position.
Since the paper is advanced and guided to the ignition position, a relatively large amount of force is required for its operation, which is disadvantageous in that it tends to impair the feeling of operation.

The object of the present invention is to obtain a device free from such inconveniences, in which a flow control valve interposed in a gas passage leading to a gas burner is pushed by the operation of a first operating member. The second operating member for controlling the point size is pushed by the second operating member for adjusting the point size.
In a type that can freely advance to an ignition position where the amount of gas is increased, the ignition position is characterized in that the ignition position is located in front of the ignition position.

An example of implementing the present invention will be explained with reference to the attached drawings.

In the drawing, (1) shows a gas burner, (2) shows a gas passage connected thereto, and (3) shows a flow rate control valve interposed therein, and the control valve (3) shows the operation of the first operating member (4). According to this, when pushed by this, it can freely move forward from a low flame position A at the rear where the gas amount is minimum as shown in the first diagram, for example, to a high flame position B where the gas volume is maximum as shown in the fourth diagram. Valve (3)
is a switch (5a) interposed in the operating circuit of the igniter (5)
By operating the second operating member (6) prepared to operate the igniter Ha, the igniter Ha is pushed forward and increases the amount of gas as shown in the third figure, for example.

To explain further, in the illustrated example, the first operating member (4)
The second
The operating member (6) is configured as a push-button type that can freely advance against a spring, and the flow rate control valve t3J Th is always pushed by the spring to the rear closed position, as shown in FIG. 1, for example. When the first operating member (4) is tilted to the left, the valve (3) is pushed to the forward open position as shown in the fourth figure. That is, it can be operated to the above-mentioned strong fire position B, and when the second operating member (6) is pressed forward, it can be pushed thereto via the arm (6&) extending laterally as shown in the fifth figure. It can be operated to the front open position, that is, the ignition position O mentioned above.

According to its operation, the second operation member (6) further acts to press the opening/closing control valve (7) and the electromagnetic safety valve (8) in front of it to the open side, and furthermore, the second operation member (6) acts to press the opening/closing control valve (7) and the electromagnetic safety valve (8) in front of it toward the opening side. (3
) is prepared to open and close the large fish passage (9a), and has a second flow control valve (5a) on its side that opens and closes the medium flow passage (9b), and a small flow lid passage on its side. (?C) and the gas mt- led to the burner 11) as a whole.
I made it work to moderate it.

Although the above is not particularly different from what was proposed earlier, according to the present invention, as described above, the high flame position B shown in the fourth figure is set at a position in front of and beyond the ignition position C shown in the third figure. I made it. In other words, the control valve (3) advances relatively far from the rear closed position, that is, the above-mentioned low fire position A, to reach the high fire position B, and also advances relatively little to reach the ignition position 0. I made it possible to obtain it.

Furthermore, as shown in Fig. 3, the valve (
When the second operation member (6) is pressed to open the valve after the ignition operation is completed, the gas supplied to the gas burner is rapidly reduced, which may cause a misfire. However, since the valve opening position where the valve (3) is pressed by the second operating member (6), that is, the ignition position, is not fully open at a position rearward from the high flame position, the amount of gas supplied through the large flow passage (9a) is is restricted by the valve (3), which also has the advantage of preventing misfires caused by the sudden decrease in gas amount.

To explain its operation, if the first operating member (4) is placed in the right position in the drawing, the flow rate control valve (3) is not pressed by it, and thus the valve (3) is, for example, as shown in the first drawing. As shown in FIG. Considering the case where the first operating member (4) is moved to the left in the drawing, the control valve (
For example, as shown in the fourth figure, 31 is pushed forward greatly to reach the high flame position B where the amount of gas is maximum, and when the second operating member (6) is operated from this state, 1. The valve (3) is not pushed forward by the member (61) and remains in the previous strong fire position B. That is, the second operating member (61)
) does not exert any effect on the control valve (31) even when the member (61) is operated.In other words, the member (61) is not subjected to any load by the valve (3) during its operation.

According to the present invention, the ignition position of the first operating member of the flow control valve is set to a position in front of and beyond the ignition position of the second operating member, and When in the strong position, the second operating member does not act as a load on the valve during its operation, which has the effect of eliminating the above-mentioned disadvantages that would otherwise occur when the second operating member acts as a load.

[Claims] According to the operation of the first operating member, the flow rate control valve inserted in the gas passage leading to the gas burner is pushed by the flow control valve from the low flame position at the rear with the minimum gas amount to the high flame position in front of it where the gas volume is maximum.
