には行われず、ガスが浪費される欠点があつた。 Conventional gas water heaters of this type, which keep the pilot burner constantly burning and ignite and extinguish the main burner by opening and closing the faucet, fail because the pilot burner continues to burn even when the water heater is not producing hot water. Coupled with the fact that people often forget to turn off the lights when using them, gas was wasted and this was extremely uneconomical. Therefore, in order to increase the energy-saving effect, it is structurally possible to extinguish the pilot burner each time, but it is generally not done because extinguishing and reigniting operations are extremely troublesome, and there is a drawback that gas is wasted.

所望の給湯が行われるものである。 In the above configuration, when supplying hot water, the faucet operating shaft 1 is rotated in a fixed direction (counterclockwise in FIGS. 3, 4, and 8) by holding the operating knob 24 while involving the return torsion spring 7. and,
First, only the cam body D is attached to the faucet operating shaft 1 by the play angle θ (45° in the figure) between the fitting hole 9 of the connecting body 6 and the engagement pin 8.
The faucet operating shaft 1 rotates as shown in Fig. 8.
When the angular position is reached from a' to b', the engaging pin 8 is engaged with the side wall of the fitting hole 9 (see the angular position from the solid line position to the chain line in Fig. 3), and from then on, the faucet operating shaft 1 The cam body D and the faucet V 1 rotate together as one, and the faucet V 1 separates from the valve seat 10 because the screw shaft 5a of the valve stem 5 is screwed into the valve housing G. The water supply channel 2 is opened and water supply to the heat exchanger 19 via the hydraulic response device F is started. Faucet operation shaft 1
When the rotation angle reaches the angular position b in FIGS. 4 and 8 (135° as shown), the operating convex portion 3 of the cam 3
One end of the valve stem 12 begins to engage with the point a, and the valve stem 12 is pushed to the left in the drawing (the same applies hereinafter in FIGS. 1 and 2) against the return spring 13. Therefore, valve stem 1
2 reaches approximately the middle of the slope portion 3a' of the convex portion 3a for operating the cam 3, the shutoff valve V3 is pressed against the valve seat 25 and closed. Closing of the shutoff valve V3 is reliably performed while there is play l in the axial direction provided at the engagement portion between the tip of the valve shaft 12 and the gas safety valve V2 . Then, when the play l ends, the engagement stepped portion 26 of the valve stem 12 is abutted and engaged with the gas safety valve V 2 and is coupled in the axial direction,
Thereafter, the valve stem 12 and the gas safety valve V 2 move to the left together, and the gas safety valve V 2 is released from its valve seat 27 (see the position indicated by the solid line in FIG. 2), and the bypass gas passage 18 is opened. Gas is supplied to the pilot burner P through the conduit 28, and the adsorption iron piece 17, which is integrated with the gas safety valve V2 , is pressed against the adsorption surface of the electromagnet, and at the same time, the actuating protrusion 4a of the cam 4 switches on the changeover switch S1 and the short-circuit switch S. 3 , the pressed state is released, the changeover switch S1 is switched, the capacitor C is connected to the electromagnetic coil M, and the shorting switch S3
is turned off, and the electrical short circuit between the electromagnetic coil M and the thermocouple TC is broken, so that the electromagnetic coil M is energized. In addition, the igniter switch S2 is turned on and the igniter IG is also energized to emit a spark from the ignition plug 20 and ignite the pilot burner P. At this time, the valve shaft 12 is connected to the operating convex portion 3a of the cam 3.
is engaged with the top of the leftmost position. (See solid line position in Figures 2 and 4). The series of ignition operations described above are performed continuously by rotating the faucet operating shaft 1 from the rotation end, that is, from the angle position a' to the angle position a (180 degrees in the figure) in FIG. When the pilot burner P is ignited, when the user releases the operating knob 24 to release the rotational force of the faucet operating shaft 1, the cam body D is caused to engage the connecting body 6 by the torque of the returned torsion spring 7. Until the side end of the matching hole 9 hits the engagement pin 8, that is, the valve shaft 12 and the operating rod of the igniter switch S2 are rotated clockwise together with the faucet operating shaft 1 by the play angle θ. The valve stem 12 is removed from the operating protrusions 3a and 4a (see the position indicated by the chain line in Figure 4), and the valve stem 12 is moved back to the right by the return spring 13, and the shutoff valve V3 is removed.
is opened away from the valve seat 25 to connect the downstream side 15b of the gas passage 15 to the gas supply source to supply gas to the main burner H, causing the main burner H to burn, and turning off the igniter switch S2 to turn off the electromagnetic The excitation current of coil M is gradually transferred from capacitor C to thermocouple.
The gas safety valve V2 , which is delivered to the TC, is kept open and the spark from the spark plug 20 is stopped. Water is supplied to the heat exchanger 19 when the water faucet V 1 reaches its full open position between the angular positions b' and a in FIG. Water is supplied through the hydraulic response device F, heated by the flame of the main burner H, and the desired hot water is supplied.

参照）。 Next, to stop hot water supply, turn the faucet operating shaft 1 clockwise from angular position b to a' in FIG. is engaged with the engagement pin 8, and these are connected together and work together, so the faucet V1 is shown in Fig. 8b.
During the angular position a', that is, within the range of rotation angle θ'' of the faucet operating shaft 1, the valve is fully opened, the water supply to the heat exchanger 19 is cut off, and the automatic gas valve is closed by the hydraulic response device F. The gas supply to the main burner H is also cut off, and the cam body D returns to its original position, and the short circuit switch S3 engages and is pressed by the operating convex portion 4a, turning on and turning on the thermocouple.
Since the thermal electromotive force of the TC is short-circuited, the electromagnetic coil M is immediately demagnetized, the gas safety valve V2 is closed, the pilot burner P is also extinguished, and the changeover switch is
S1 is connected to the DC power source E in preparation for the next ignition operation. (See the position of the solid line in Figures 1 and 3).

い。 Incidentally, the electromagnetic coil M can be demagnetized by using the charging current of the capacitor C instead of the short-circuit switch S3 , and in this case, it is necessary to change the related parts and their connecting wiring. In addition, a flame detection device different from the thermocouple is installed, and the detection signal is used to detect the electromagnetic coil M.
may be excited. Furthermore, move the faucet operating shaft 1 from the ignition position of the pilot P (angle position a in Figure 8) to the ignition position of the main burner H (angle position b in Figure 8).
Although a case has been described in which the rotation is performed automatically by the rotation spring 7, this may also be performed manually.

There is no problem even if this structure is closed when extinguishing a fire.

き、その使い勝手も良好なものである。 As explained above, this invention has a structure in which water flow and ignition of the pilot burner point and the main burner are performed in conjunction with the rotational operation of the faucet operating shaft, so relighting is not a hassle, and the pilot burner is activated each time. Since the gas can be extinguished and there is no need to forget to turn it off when not in use, unnecessary waste of gas is eliminated and the energy saving effect is significantly increased. In addition, its operation is smooth, reliable, and safe because it moves the valve stem forward and backward through a cam mechanism, and hot water can be supplied by checking the ignition status.Therefore, there is a risk of gas leakage due to ignition errors or malfunctions. It can always be used safely and is easy to use.
