る。 Conventionally, this type of automatic hot water supply system for baths has been constructed as shown in Fig. 1, in which hot water discharged from a water heater 1 is mixed with water by an automatic mixing valve 2 so as to have an appropriate temperature, and then a solenoid valve is operated. Hot water is supplied to the bathtub 4 via a bathtub 4, and the electromagnetic valve 3 is controlled by the output of a water level detector 5 that detects the water level in the bathtub 4. In the figure, 6 is water supply,
7 is a hot water temperature adjustment knob, 8 is a hot water supply control unit, 9a, 9
b is a faucet fitting. FIG. 2 shows an example of the configuration of the hot water supply control unit 8, in which 11 is a power transformer that steps down the commercial power AC, 12 is a diode bridge, 1
3 is a smoothing capacitor, 5a is an output contact of the water level detector 5, 14 is a full water indicator lamp, 15 is a load control relay, 3a is an excitation coil for the electromagnetic valve 3, and 16 is a hot water supply start switch consisting of a push button switch. Now, when the hot water supply start switch 16 is pressed, the relay 15 is operated and the excitation coil 3a of the solenoid valve 3 is energized via the relay contact 15a, the solenoid valve 3 is opened, and hot water supply is started. At this time, relay 15
is self-held by relay contact 15a. Next, when the water is full, the output contact 5a of the water level detector 5
The normally closed side of is turned off, the relay 15 and the solenoid valve 3 are turned off, the solenoid valve 3 is closed, and at the same time hot water supply is stopped, the normally open side of the output contact 5a is turned on and the full water indicator lamp 14 lights up. Note that when the water level in the bathtub 4 becomes lower than a preset value by draining the water, the normally closed side of the output contact 5a of the water level detector 5 is turned on and automatically set to a standby state.

決することを目的とするものである。 By the way, in such a conventional example, when the normally closed side of the output contact 5a of the water level detector 5 is turned off,
Even when the hot water supply start switch 16 was pressed, the solenoid valve 3 could not be opened to supply hot water, so if additional hot water supply was required, the faucet fittings 9a and 9b were separately installed.
was beginning to be established. Therefore, in the conventional example, the number of piping and faucet fittings increases, which complicates the configuration, resulting in an increase in cost.In addition, the water spout to the bathtub becomes complicated, resulting in an unsightly appearance. Ta. The present invention aims to solve the above problems.

ワー２０と、浴槽４とに切換える切換弁である。 Examples will be described below using figures. Third
The figure and FIG. 4 show one embodiment of the present invention.
The general configuration is the same as the conventional example, but the difference from the conventional example is that a ratchet relay 10 is used as a load control relay that controls the solenoid valve 3, and the ratchet relay 10 is connected to the water level detector 5 output and the manual operation switch 17a, 17b output. This is the point where the step-down transformer 11 and the diode bridge 1 are controlled.
2 and the smoothing capacitor 13 are applied to the excitation coil 3a of the solenoid valve 3 via the relay contact 10a of the ratchet relay 10. A DC power supply V DC is applied through the normally open side of the output contact 5a of the water level detector 5 and the capacitor 1.
A DC power supply V DC is applied via 8. Here, the ratchet relay 10 closes the relay contact 1 every time the DC power supply V DC is applied in a pulsed manner.
This is a latching relay in which 0a is inverted (off->on, on->off), and can also be realized by an electronic circuit using a flip-flop and a switching circuit controlled by the flip-flop output.
In the figure, reference numeral 19 denotes a switching valve that switches the hot water supplied via the electromagnetic valve 3 to the shower 20 and the bathtub 4.

き、構成が簡単になつている。 Now, when the solenoid valve 3 is closed, when the manual operation switch 17a, which corresponds to the conventional hot water supply start switch 16, is pressed, the ratchet relay 10 operates in reverse, the relay contact 10a turns on, and the solenoid valve 3 opens. Then hot water supply starts. Next, when the water level in the bathtub 4 reaches a predetermined level and the normally open side of the output contact 5a of the water level detector 5 is turned on, a pulse current flows through the capacitor 18 to the ratchet relay 10, and the ratchet relay 10 operates in reverse. The relay contact 10a turns off, and the solenoid valve 3
is closed and hot water supply is stopped. In this state, the manual operation switch 17 located in bathroom B
When b is pressed, the ratchet relay 10 is reversed, the relay contact 10a is turned on, the solenoid valve 3 is opened, and hot water is supplied regardless of the water level in the bathtub 4. Further, when the manual operation switch 17b is pressed again, the ratchet relay 10 moves in reverse again, the solenoid valve 3 is closed, and the water supply is stopped. Therefore, hot water can be supplied via the solenoid valve 3 when using the shower 20 or when taking a bath (when entering the bathtub 4), and requires separate piping and faucet fittings 9a, 9b is not necessary, the structure is simplified, the cost is reduced, and since there is only one discharge port to the bathtub 4, the appearance is good. Furthermore, the manually operated switches 17a and 17b can be used to start automatic hot water supply and to start and stop additional hot water supply, resulting in a simple configuration.

う利点がある。 As described above, the present invention provides an automatic bath system in which hot water discharged from a water heater is supplied to a bathtub via a solenoid valve, and the solenoid valve is controlled by the output of a water level detector that detects the water level in the bathtub. In the water heater, power is applied to the excitation coil of the solenoid valve via the relay contact of the latchet relay, power is applied to the latchet relay via a manually operated switch consisting of a push button switch, and a full water signal is obtained from the water level detector. In some cases, a pulse drive circuit that applies power in pulses to the ratchet relay is installed, so automatic hot water supply that automatically stops hot water supply based on the output of the water level detector, and optional additional hot water supply based on the output of a manual operation switch, are performed using the same solenoid valve. This can be done via
This has the advantage that the structure is simple, the cost is low, and there is only one outlet for the bathtub, which improves the appearance.
