Have been. Therefore, the above-mentioned control unit 15 is provided with a heat retention control unit 20. Hereinafter, the operation will be described with reference to the graph of FIG. In this embodiment, the program of the heat retention control unit 20 is executed at the same time as the operation is stopped by the 24-hour timer 16.
This program basically consists of a separate timer 2
According to 1, the leaving step (for example, 3 hours) and the heat retaining step (for example, 30 minutes) are alternately repeated. In addition, the temperature range where bacteria do not grow is planned to be 50 ° C to 85 ° C,
The reference temperature of the temperature increase set in the heat retention control unit 20 is 50 ° C.
It is adjustable between 85 ° C. Hereinafter, a case where the reference temperature of the temperature increase is set to 60 ° C. is illustrated.

During this time, the temperature of the hot water in the hot water storage tank 1 gradually decreases. After 3 hours, the temperature of the hot water has dropped to, for example, about 50 ° C., and the heat retaining step is subsequently started.
In this heat retaining step, the hot water temperature detected by the temperature sensor 7 and the reference temperature (60
(° C.), the power cutoff to the heater 6 is controlled, and the temperature of the hot water stored in the hot water storage tank 1 is maintained at the reference temperature. Specifically, if the temperature of the hot water is lower than the reference temperature (60 ° C.) at the time when the heat retaining step is started, the heater 6 is energized to increase the temperature of the hot water.
Is cut off, and this is repeated thereafter, during the warming process,
Hot water temperature is maintained at approximately 60 ° C. After a lapse of 30 minutes, the process shifts to the leaving process again. After a lapse of 3 hours when the temperature of the hot water drops to about 50 ° C., the process enters the heat retaining process again.

In addition, the germs are prevented from growing in the hot water storage tank 1. In addition, the heater 6 is energized only during the warming process and only a part of the process.
As compared with the case where the inside is maintained at the set temperature, the power consumption can be greatly reduced. In addition, since the program of the heat retention control unit 20 is incorporated in the 24-hour timer 16 and executed, the program can be reliably executed by a simple control system. In addition, the temperature range in which the propagation of various bacteria can be suppressed may vary depending on conditions such as the amount of hot water stored in the hot water storage tank 1 and how easily various bacteria enter the hot water storage tank 1. Therefore, the temperature may be arbitrarily selected in a temperature range equal to or lower than the discharge temperature (90 ° C.) according to conditions. At the same time, a reference temperature for controlling the power cutoff of the heater 6,
The time for the standing step and the time for the heat retaining step can also be set arbitrarily.

FIG. 3 shows a second embodiment of the present invention. In the second embodiment, when the operation is stopped, the temperature sensor 7
Is compared with a reference temperature (for example, 60 ° C.) set in the heat retention control unit 20. If the hot water temperature is lower than the reference temperature, the heater 6 is energized to increase the hot water temperature. If the temperature is exceeded, the heater 6 is turned off, and this is repeated thereafter, so that the temperature of the hot water is maintained at about 60 ° C. in a temperature range in which propagation of various bacteria can be suppressed.

The interval a is the interval b when the set temperature is maintained.
, That is, the electricity supply rate to the heater 6 can be reduced. Thereby, while suppressing power consumption, generation and propagation of various bacteria in the hot water storage tank 1 can be prevented. Also in this case, the reference temperature can be arbitrarily selected according to the use conditions and the like.

In the control mode of the third embodiment, the temperature of the hot water in the hot water storage tank 1 is raised to the reference temperature (60 ° C.) every time a predetermined time elapses during the suspension of operation. That is, when the operation of the tea dispenser is stopped, the heater 6 is left in the off state for a predetermined time (for example, 3 hours: a leaving step). After 3 hours when the temperature of the hot water drops to about 50 ° C,
The heater 6 is energized to increase the hot water temperature, and when the hot water temperature reaches the reference temperature (60 ° C.), the heater 6 is turned off. Thereafter, the above operation is repeated. Here, too, the temperature of the hot water in the hot water storage tank 1 is set to 50 ° C. which can suppress the growth of various bacteria.
に 60 ° C. Since the power supply to the heater 6 is performed only for a short time every three hours (temperature raising step),
Low power consumption is required. Similarly, the temperature range to be held can be arbitrarily selected according to the conditions, and the time of the leaving step and the reference temperature for controlling the disconnection of the heater 6 can be arbitrarily selected.

In the control mode of the fourth embodiment, when the temperature of the hot water in the hot water storage tank 1 decreases to a predetermined temperature during the suspension of operation, the temperature is raised for a predetermined time. That is, when the operation of the tea dispenser is stopped, the heater 6 is left in the off state.
When the temperature sensor 7 detects that the temperature of the hot water has dropped to the reference temperature (60 ° C.), the heater 6 is energized for a predetermined time t to increase the temperature of the hot water to about 70 ° C. Thereafter, the above operation is repeated. Here, the temperature of the hot water in the hot water storage tank 1 is maintained in a temperature range of 60 ° C. to 70 ° C., thereby preventing the growth of various bacteria in the hot water storage tank 1. In this temperature range, the hot water is relatively difficult to cool,
Since the number of times of power supply to the power supply can be reduced, power consumption can be suppressed. Also in this case, the temperature range to be held can be arbitrarily selected according to the conditions, and a reference temperature for controlling the energization of the heater 6,
The energization time t of the heater 6 can also be arbitrarily selected.
