An inverter control circuit 20 for the switching circuit is connected to the switching circuit 15.
The switching circuit 15 is actuated to drive the bomb drive motor M at a desired output frequency.

Further, an operation panel l1 is connected to the inverter control circuit 20 via a control unit lO, and the inverter I is operated by the panel l1. Based on the program stored in the control unit IO, the human power frequency from the single-phase AC 100V power supply 16 is converted by the inverter 1.

The number of revolutions of the pump driving motor M is controlled in proportion to the output frequency converted by the inverter I.

Further, in the present invention, changes in the amount of water spouted from the water spouting fitting 2 provided in the bathtub B etc. are controlled, and the structure thereof will be explained in detail below.

That is, as shown in FIG. 1, a flow rate control valve 24 is provided in the middle of the supply channel 8 connected to the water spout 2a.
The flow rate control valve 24 controls the amount of water spouted from the water spout 2a in a variable manner.

Further, a valve opening/closing motor M2 is linked to the flow rate regulating valve 24, and the valve 24 is opened/closed by the motor M2.

Furthermore, in this embodiment, the inverter I-2 periodically operates the valve opening/closing motor M2, and the periodic operation of the motor M2 opens and closes the flow control valve 24, thereby discharging the water from the water spouting cylinder 2a. The amount of water is changed periodically.

By periodically changing the water discharge flow rate, the flow rate and the state of water flowing into the bathtub B can be freely changed. Also, Figure 3 shows the inverter! -2 shows the amount of water discharged when the valve opening/closing motor is periodically changed. By controlling the inverter I-2 as described above, the flow I1
The opening/closing operation of the jl control valve 24 is performed continuously to periodically change the flow rate of shower water.

In this embodiment, the upper limit opening amount and the lower limit opening amount of the flow N control valve 24 are programmed in the control unit 10, and the valve opening/closing motor M2 is periodically operated within the range.

By opening and closing the flow fi 18-node valve 24, as shown in FIG. 3, the amount of water discharged is varied in the range between the upper flow limit l1?1 and the lower limit 'tHH2.

Further, in the present invention, when hot water is supplied from the water source 4 to the bathtub B via the water spouting fitting 2, the temperature and flow rate of the hot water are changed.

That is, as shown in Figure 5, when starting to fill with hot water, 4
Hot water of 5°C or higher is supplied little by little, and as time passes, the temperature of the hot water is gradually lowered to supply a large amount of water from the water source 4.

By filling the hot water as described above, the hot water in the bathtub B is brought to a temperature of 40 to 44 degrees Celsius, which is suitable for bathing.In addition, by filling the hot water in this way, the thermal efficiency of the hot water is lower than when supplying a constant temperature at a constant flow rate. In addition, hot water can be filled in a short time.Therefore, fuel costs for the water heater serving as the water source 4 can be saved, and hot water can be supplied economically.
