点灯又は鳴動等の警報を出力するものである。 In FIG. 2, TM is a timer which is a main part of the present invention, and 16 is an alarm activated by closing the normally open contact TM1 of the timer TM.
The timer time is appropriately set to a predetermined time T (time equivalent to the time required to obtain an arbitrary predetermined amount of hot water) by a variable resistor VR connected to the timer TM, and a reaction linked to the flow switch 12 is performed. When an ON operation signal is received by closing the switch 17, and this reception state continues for the predetermined time T, the normally open contact TM1 is closed and an alarm signal is output. Further, the alarm device 16 is composed of a warning indicator light and a warning buzzer provided in a part that can be easily seen by the user, and is turned on in response to an alarm signal caused by the closing of the normally open contact TM 1 of the timer (TM disconnection). Or outputs an alarm such as a sound.

ある。 In FIG. 2, 18 is a hot water thermostat that closes when the water temperature in the hot water storage tank 1 is below a predetermined value, and 19 is a compressor that turns ON when the hot water thermostat 18 is closed and operates the compressor 4. It is a relay for use.
In addition, 20 in FIG. 1 is a ball tap valve,
When the water level in the hot water tank 1 falls below a predetermined value, the supplementary water pipe 2
This control allows water to be supplied from the tank 1 and replenishes water into the tank via an internal water replenishment pipe 22 disposed inside the hot water tank 1. Further, 23 is a check valve provided in the hot water supply passage 10, 24 is a solenoid valve for preventing freezing of pipes in the machine, 25 is a hot water discharge valve, and 26 is an overflow pipe.

ON作動信号が入力されている。 Next, to explain the operation of the above embodiment,
When the hot water supply faucet 11 is in the open state, the pressure inside the hot water supply passage 10 is below a predetermined pressure, and the hot water supply passage 1
Since hot water is flowing through the valve 0, both the pressure switch 14 and the flow switch 12 are turned ON. Therefore, the hot water pump 8 operates and the hot water tank 1
The hot water inside is fed under pressure from a suction passage 9 through a hot water supply passage 10 to a hot water tap 11. In addition, when the flow switch 12 is turned on, the reaction switch 17 is also turned on.
The timer TM is activated and the flow switch 12 is activated.
ON activation signal is input.

１６の誤動作を確実に防止することができる。 Now, if the hot water tap 11 is operated to close before a predetermined time T has elapsed after the flow switch 12 is turned ON, the pressure in the hot water supply passage 10 becomes higher than the predetermined pressure and the pressure switch 14 is turned OFF. At the same time, hot water no longer flows into the hot water supply passage 10, and the flow switch 12 is turned OFF. Therefore, the power supply circuit 8a of the hot water supply pump 8 is opened, the operation of the hot water supply pump 8 is stopped, and the pressure feeding of hot water to the hot water tap 11 is stopped. At this time, the flow switch 1
The reaction switch 17 is activated in conjunction with the OFF operation of 2.
OFF is activated and timer TM is reset. Therefore, the normally open contact TM1 of the timer TM remains open and the alarm 16 does not output an alarm. At this time, since the stop of hot water supply is detected by the flow switch 12, the timer TM can be reset without delay in the closing operation of the switch 11, and malfunction of the alarm 16 can be reliably prevented.

の分、コストを低減することができる。 On the other hand, the hot water tap 11 remains open for a predetermined period of time T.
When the supply of a predetermined amount of hot water is completed, such as continuously supplying hot water to a bath, the hot water pump 8 continues to operate by keeping the pressure switch 14 and flow switch 12 ON, and from then on, when the hot water supply pump 8 continues to operate by maintaining the ON operation of the pressure switch 14 and flow switch 12, This results in a situation where hot water is forced to be fed to the hot water tap 11. At this time, the timer TM closes its normally open contact TM 1 for a predetermined period of time T, generates an alarm signal, and outputs it to the alarm 16 . Therefore, the alarm device 16 outputs an alarm to stop the hot water supply by closing the hot water tap 11. As a result, the user is alerted by the alarm output from the alarm device 16 and can quickly close the hot water tap 11, thereby eliminating wasted hot water supply and effectively using the hot water in the hot water storage tank 1. It can be used for. Further, in this embodiment, since the flow switch 12 is provided in advance as a component of the control circuit 15, the cost can be reduced accordingly.

停止を行うことができ、より好ましい。 In the above embodiment, when the predetermined amount of hot water has been supplied, the alarm 1 is activated based on the alarm signal from the timer TM.
In addition to this, a solenoid valve for opening and closing the hot water supply passage 10 is provided in the hot water supply passage 10, and the operation of the hot water supply pump 8 is forcibly stopped by the alarm signal from the timer TM. If the electromagnetic valve is closed, hot water supply can be automatically stopped, which is more preferable.
