After the pressure is released, the safety valve α0) is opened by discharge from the capacitor α until a predetermined electromotive force is generated from the thermocouple 00 placed on the pilot burner (2b). I held it in a valve state and tried to fish.

The water valve (4) is constituted by a spool-type valve, and the second operating rod Qv that is linked with the operating member (noted separately) is fully connected, and the operating member (6) is pressed from the starting end position A. so that the water valve (4) is opened at the intermediate position 0-''C to a predetermined value, and then the operating member (6) 1 is opened.
With the suppression operation twice, water is supplied to the heat exchanger fi+, and as described above, the gas control unit (4) is ignited to the burner unit (2) with all valves set, and hot water tapping operation is not obtained. I did it like that.

In the drawing, C4 indicates an automatic valve installed in the main gas passage (8) on the downstream side of the second gas valve 02. 1 The automatic valves are connected to a water flow detector (22aJ) such as a water governor. Heat exchanger(]
) The valve opens when water is passed through. Further, in FIG. 1, (231 is a tap port connected to the outlet side of the heat exchanger (1).

Although the above is not particularly different from the above-mentioned previous proposal, present invention 1/C, 1: n, a control means for inactivating the gas control unit (31'c) even when the operation member (6) is operated. (L:'i'1- is provided in more detail. In the illustrated example, the means C!41 is a combination of the plate operating member (6) and the first operating rod (14). A connecting rod ψ51fr with a valve leaf in between is provided so as to be shiftable between an interlocking position where it abuts the front end of the first operating rod α and a non-interlocking position on its side. After cutting, the holder (20r) is movably inserted and is slidably supported in the horizontal direction on the fixed frame (27). 2?) installed horizontally on the shift rod (2 stamps inserted, the shift rod is inserted). As shown in Figure 2, by sliding to the left, the E ring (28a)

261w accompanied by C! According to the operation VC of the cough operating member (6) in this state, the connecting lever (c) moves to the first non-interlocking position as shown in the fourth figure.
Run away to the side of the control circle and move #1! 1 operation of each operation lever, and therefore the operation sound of the gas control unit (3) through N2 was prevented from occurring.

Here, the shift rod (C) may be configured to be able to be operated independently, but in the illustrated one, the shift rod (2~?) may be operated independently.
Interlock the temperature control lever (7) from 8-#+-4 to 1, that is, swing the temperature control lever (7) beyond the normal m adjustment operating range to the "water" position shown in Figure 1. Try to get this "water"
By swinging to the position, the part (7a) formed by the cough temperature control lever (7HC) comes into contact with the right end of the shift rod (C), and the rod (C) moves to the left. □□□ is shifted to the non-interlocking position, and even though the operating member (6) is operated, the gas control unit (3) becomes inactive, and only 1 water pulp +41 is operated, and the output connected to the heat exchanger (1) is Hang water from the sprue.In this case, use the temperature control lever (71'(i-
Reset the temperature within the operating range and adjust the operating member (6) to the starting position.

To return to the human position, the connecting rod (c) returns to the interlocking position, so next is the operating member (6)? The operation can be performed to release hot water.

Note that the ft1t control means (to) is not limited to the one in the above embodiment; for example, an electromagnetic safety valve (10
It is also possible to configure a configuration in which all operation switches are connected in series to the solenoid 1 (10); in this case, the switch (

The burner unit (2) is no longer supplied with gas, and the gas control unit (3) becomes essentially inoperative.

In this way, according to the present invention, a control means is provided to disable the gas control unit even when the operating member is operated. Only water pulp is produced by manipulating evil material V? Does it have an actuated type and only allows water to flow without activating the burner unit? This has the effect of making it easier to use than the previous proposal, in which both the gas control unit and the water valve are always operated by operating the operating member.
