Abstract

PURPOSE:To permit to obtain necessary amount of tap-delivery hot-water even when an operating unit is displaced to a position in which gas is supplied to a main burner by a method wherein the operating unit is provided with a play margin in the operating direction of a water cock and the play is made equal to the displacing amount of the operating unit. CONSTITUTION:An operating lever 22 and a gear 23 are constituted so as to mesh through sawtooth-like gears 24, 24... regulating the meshing angles so as to close a solenoid valve 1, a main valve 5 and a sub valve 13 at the same time under being pivoted integrally. The gear 23 is fitted loosely to the water cock 17 with a play (a) in the rotating direction of a pin 25 inserted into a loosely inserting hole 23a and the water cock 17. The main operating cam 26 and the operating lever 22, which are made of synthetic resin, are engaged with the play (b) in the rotating direction of the operating lever 22 while the operating lever 22 and the main operating cam 26 are retained by a lever spring 27 so as to be attracted mutually. According to this constitution, the water cock 17 will never be closed even when the operating unit 38 is displaced to a position in which the gas is supplied to a main burner and is ignited.

Activate the device and ignite. The other end (46b) of the ~ direction stopper (46) slides on the side surface of the sub valve cam (52) as the main rod F (43) slides, and the retaining portion (53
), one end (46a) of the stopper (46) fits into the recess (45) of the sub-rod (44) due to the biasing force of the spring, and the other end (46b) engages the sub-valve cam (5).
2) engages with the engaging portion (53). At this time, the solenoid valve shaft (2
) is the ONL switch (not shown), from the power supply circuit! Supply power to the magnet (3). Then, the electromagnet (3) is activated to keep the electromagnetic valve (1) open for a certain period of time. After a certain period of time has elapsed, the electromagnet (3) is activated by the thermoelectromotive force of the flame detection plug that detects the combustion flame of the main burner ignited at the third position of the operating lever (22), which will be described later.
Keep the solenoid valve (1) open. If the main burner does not ignite, or if the main burner is extinguished by outside wind, the electromagnet (3) will not operate and the solenoid valve (1) will be closed. In this state, the sub-valve (13) is open and no gas is supplied to the main burner. At this time, the operating bar (22>) is the main operating cam (26), and the regulating rib (31) on the bottom surface is connected to the plate spring (28) and the locking screw (30).
The rotation is restricted by contacting with, and cannot be rotated to the right from the second position. In this second position, 1 & 1 bar (9'))
When the user releases his/her hand, the operating lever (22) returns to the third position shown in FIGS. 7 and 8 due to the biasing force of the lever spring (27). This point will be explained in detail below.

Since the leaf spring (28) is in elastic contact with the control lever (22), it is held in the second position, but the control lever (22>) is not in contact with the main control cam (
Due to the biasing force of the lever spring (27) which is disposed between the gear (26) and the lever spring (27), the gear (23) returns to its original position by the amount of play a provided in the gear (23). At this time, the free play a is the second one of the operating lever (22).
Since the displacement amount C from the position to the third position is equal to or slightly larger, the faucet (17) will not rotate in the opposite direction in conjunction with the return of the operating T-bar (22>). Therefore, the faucet <17) is not closed. With the return rotation of the operating lever (22), the guide hole (22) of the operating lever (22)
a), the secondary operating force l, (35) is guided by the main operating cam (
26) Slide against. Therefore, the secondary operation cam (35)
A third guide groove (37) on the lower surface communicates with a second guide groove (33) on the lower surface of the main operation cam (26). And the interlocking member (
39) Rotate the main rod (43) by an angle corresponding to the sliding movement of the cam (35), which corresponds to the sliding movement of the cam (35). The actuator operating member (47) and the actuator (48) are connected to the main valve spring (
The urging force of 7) causes the interlocking member (39) to return in accordance with the rotation angle.

。, '-, the main valve 1 holding member (50) comes into contact with the upper end of the clay valve shaft (6) and holds the main valve (5) in an open state.
The main valve holding member (50) is configured to open the main valve (5) even if the return distance of the main rod (43) is long due to variations in parts. Also, when the main rod (43) returns, that is, moves to the right, the stopper (46>) moves in the same direction.However, the other end of the stopper (46>
46b) is engaged with the engaging portion <53) of the sub-valve cam (52), so that the sub-valve cam (52) pivots m (52
