If the pilot spark does not ignite, there is no input to the pilot spark sensor 1, so the pilot sensor 1 produces an output, and that output is input to the boiler ignition mechanism 44, which causes the pilot spark ignition mechanism 2 to operate again and ignite the pilot flame, but it does not work again. If the starter does not ignite even with the operation, alarm 4
5 and the alarm 45 sounds to alert you.

The outputs of the water temperature sensor 5, the room temperature sensor 31, and the hot water temperature setting circuit 35 are introduced into the valve opening calculating circuit 37, which calculates the valve opening corresponding to the set hot water temperature (40°C), and the output is sent to the valve driving mechanism 41. A signal is issued from the timer 43, and the electromagnetic hot water pouring valve 7 opens to a predetermined opening degree. The water is supplied to the bathtub 13.

When a predetermined amount of hot water accumulates in the bathtub 13, an output is generated in the liquid level sensor 19, and the output is introduced into the ignition mechanism 44 and the valve drive mechanism 41, the electromagnetic pouring valve 7 is closed, and pouring of hot water is stopped. A closing signal generated from the solenoid valve 2' is input to the solenoid starter valve 2', the solenoid main valve 18, and the solenoid burner valve 16, and these valves are closed.

The hot water temperature sensor 21 inputs an output corresponding to the hot water temperature in the bathtub 13 to the comparison circuit 38, and the hot water temperature setting circuit 3
5, and when the water temperature in the bathtub 13 falls below the set temperature, an output is generated in the comparison circuit 38, and the output is introduced into the ignition mechanism 48 of the burner 11, and the full water signal from the liquid level sensor 19 is output.

is heated, the hot water in the bathtub 13 flows through the circulation pipe 14.
It is circulated through the tank by convection, heated, and kept at the set temperature even after pouring the set amount.

If the pilot spark does not ignite, there is no input to the pilot spark sensor 9, so the pilot sensor 9 generates an output, and that output is introduced into the boiler ignition mechanism 48, and the pilot spark igniter 10 operates again to ignite the pilot flame, but it does not restart. If the spark does not ignite even with
9 and the alarm 49 sounds.

When the temperature of the water in the bathtub 13 reaches the set temperature, the output of the comparison circuit 38 is stopped, and the closing signal generated from the ignition mechanism 48 is input to the solenoid main valve 18, the solenoid pilot valve 10', and the solenoid burner valve 17, and these The valve closes.

When the temperature in the bathroom 28 is lower than the set temperature and the liquid level sensor 19 has an output, that is, when there is a predetermined amount of hot water in the bathtub 13, an output is generated in the bathroom temperature sensor 29, and the output is sent to the valve. The input signal is input to the electromagnetic switching valve 25 via the drive mechanism 51, and the valve is switched between the space between the bathtub 13 and the lid plate 34 and the bathroom 2.
8, the bathroom 28 is heated by the temperature of the hot water.

Conversely, when the temperature in the bathroom 28 is higher than the set temperature, the electromagnetic switching valve 25 communicates the bathroom 28 with the outside, so the temperature in the bathroom 28 is released through the exhaust pipe 23, and the temperature in the bathroom 28 is discharged through the exhaust pipe 23. Prevent temperature rise.

When the hot water in the bathtub 13 becomes cloudy, an output is generated in the turbidity sensor 20, which is introduced into the valve drive mechanism 50, which opens the drain valve 22 to drain water, and at the same time, the output of the liquid level sensor 19 causes the ignition mechanism 44 and the valve drive Mechanism 41 operates to replenish hot water.

In addition, the pump motor 26 is operated by the output of the turbidity sensor 20, and the hot water in the bathtub 13 is pumped through the circulation pipe 2.
4 and a filter 27, the dirt is filtered out and returned to the bathtub 13.

When the hot water in the bathtub 13 is pumped out, the liquid level sensor 19
The output of the ignition mechanism 44 and the valve drive mechanism 4
1 operates and replenishes hot water.

When gas leaks in the boiler room 30, an output is generated in the gas leak sensor 32, and the output is sent to the ignition mechanism 4.
4, 48 and the valve drive mechanism 41, the output of which causes the alarm 45 to sound, and the solenoid main valve 18, the solenoid pilot valve 2', 10', and the solenoid burner valve 16, 17.
and close the electromagnetic pouring valve 7.

If you want to take a bath immediately, press the emergency start switch 59 to immediately pour hot water, and press the emergency stop switch 49 to stop all functions.

The automatic control device of this invention is configured to control the time when you want to take a bath;
When you set the amount and temperature of hot water, not only will the set amount of hot water at the set temperature be poured automatically at that time, but if the water temperature drops after pouring the set amount, it will automatically warm up and supply the set amount. The set temperature can be maintained even after bathing, so even if the bathing time is delayed for some reason, the water temperature can be prevented from dropping.Also, even if the water temperature drops due to the cold body of a person in the winter, the water temperature can be automatically set automatically. It is something that can be heated.

Furthermore, not only the temperature of the water in the bathtub but also the room temperature in the bathroom can be maintained at the appropriate temperature before bathing, and there is no need to install a special heater for this purpose. Since it can be used, it has a simple configuration and is inexpensive. Furthermore, since the turbidity of the water in the bathtub can be automatically removed, bathing can be expected to be more comfortable in various aspects.
