In the gas control valve unit for controlling the gas of the burners 1, 2 and 3, the gas passages 4, 7 and 10 and the dedicated gas passage 16 for the normal-fire pilot burner 3 are formed inside. An electromagnetic safety valve 5, a main valve 6, a water pressure responsive valve 8, a governor 9, a gas valve 11, and a governor 12 are provided at 10.

Reference numeral 17 denotes a manifold having therein a gas chamber 18 for the hot water supply burner 1, a gas chamber 19 for the bath burner 2 and a gas chamber 20 for the normal fire pilot burner 3, and corresponds to the gas chamber 18 on the outer surface. A plurality of hot water supply nozzles 21 communicating with the gas chamber 20 are provided at positions, and a plurality of bath nozzles 22 communicating with the gas chamber 19 are provided at positions corresponding to the gas chambers 19.
A normal fire pilot nozzle 23 communicating with this is provided at a position corresponding to.

The gas control valve unit 13 and the manifold 17 are connected at their flange portions 13a and 17a.

At this time, the electromagnetic safety valve 5 is operated by the first pressing operation of the push button 14 for the main operation and the subsequent release of the pressing.
The main valve 6 is opened, and the spark of the ignition device 30 ignites the normal-fire pilot burner 3.

When the pilot pilot burner 3 is ignited, the thermocouple 24 facing it is heated, and a predetermined electromotive force generated by the thermocouple 24 keeps the electromagnetic safety valve 5 open. At this time, the main valve 6 is also opened and held by the push-push type valve opening holding device A.

In this state, if a water faucet (not shown) is opened, the water pressure responsive valve 8 is opened, the hot water supply burner 1 ignites from the pilot pilot burner 3 at normal temperature, hot water supply is started, and if the water faucet is closed, the water pressure responsive valve 8 is opened. When closed, the hot water supply burner 1 is extinguished and the hot water supply is stopped.

On the other hand, by the first pressing operation of the push button 15 for bath operation and the subsequent release of the pressing, the gas valve 11 is opened, the bath burner 2 is ignited from the permanent pilot burner 3 and the bath is reheated. Is started. At this time, the gas valve 11 is held open by the valve holding device A.

Further, by the second pressing operation of the push button 15 and the subsequent release of the pressing, the valve opening holding by the valve opening holding device A is released, the gas valve 11 is closed, the bath burner 2 is extinguished, and the bath burner 2 is extinguished. Reheating stops.

Further, by the second pressing operation of the push button 14 and the subsequent release of the pressing, the valve opening holding by the valve opening holding device A is released, the main valve 6 is closed, and the gas supply to the normal-fire pilot burner 3 is performed. Is stopped and the balanced gas bath kettle is deactivated.

When the normal fire pilot burner 3 misfires, the electromotive force of the thermocouple 24 decreases, the electromagnetic safety valve 5 closes, and the supply of gas to the burners 1, 2, 3 is stopped.

Here, the method of connecting the gas control valve unit 13 and the manifold 17 will be described in detail. The flange portion 13a of the gas control valve unit 13 and the flange portion 17a of the manifold 17 are used for the hot water supply burner 1, the bath burner 2, and the bath burner 2. Gas passage holes 25a, 26 for the constant fire pilot burner 3
a, 27a and gas passage holes 25d, 26d, 27d are formed, and the gas control valve unit 13 and the manifold 17 are connected to the gas passage holes 25c, 26c, 27c for the respective burners at the flange portions 13a, 17a of the both. The partition plate 28 thus formed is interposed and assembled. In this case, gas passage holes 25a, 26a, 27a for each burner formed in the flange portion 13a of the gas control valve unit 13 and between the flange portion 13a and the partition plate 28 and the partition plate 28 are provided.
The rubber packings 29, 29 provided with the gas passage holes 25b, 26b, 27b interposed between the flange portion 17a of the manifold 17 and the manifold 17a can be used for both the right water pipe type and the left water pipe type. These gas passage holes 25a-2
5d, 26a to 26d, 27a to 27d, gas passage 25 for hot water supply burner 1, gas passage 2 for bath burner 2
6. A gas passage 27 for the normal fire pilot burner 3 is formed. In the case of the right water pipe type, as shown in FIG. 3, the partition plate 28R having the gas passage holes 25c, 26c and 27c and the manifold 17R are selected to select the gas control valve unit 1
3 and the gas passages 25 and 26 of both burners 1 and 2 between the manifold 17R and the gas chamber 7 for the hot water supply burner 1 of the manifold 17R by the gas chamber 18 and the gas passage 25 of the manifold 17R do not intersect. The gas passage 10 in the gas control valve unit 13 is communicated with the gas chamber 19 for the bath burner 2 of the manifold 17R by the gas passage 26, and in the case of the left water pipe type, as shown in FIG. The partition plate 28L having the gas passage holes 25c, 26c and 27c formed therein and the manifold 17L are selected so that the gas passages 25 and 26 of the burners 1 and 2 between the gas control valve unit 13 and the manifold 17L are three-dimensionally crossed. The gas passage 7 in the gas control valve unit 13 communicates with the gas chamber 18 for the hot water supply burner 1 of the manifold 17L by the gas passage 25, Gas passage 10 knit 13 was made to communicate with the gas chamber 19 and gas passage 26 for bath burner 2 manifold 17L.
