In the multifunctional shower apparatus thus constructed, as shown in a timing chart of the basic function of the controller 23 in FIG. 10, when the switch SW1 is pressed, the light emitting diode LED1 is turned on and at the same time the solenoid valve SV is turned on.
1 is opened and the diode LED1 goes out after 5 seconds.
Then, when the solenoid valve SV1 is opened, hot water is sprayed from the mist showers 17, 17 in a mist state, and the spraying is stopped by pressing the push button switch SW8. Note that the voltage of the dry battery set in the battery box 56 is 4.5.
When the voltage drops below volts, this is detected, and the diode LED8 blinks during the blowing.

When the push button switch SW2 is pressed, the light emitting diode LED2 is turned on, the solenoid valve SV2 is opened and hot water is jetted from the top shower 18, and can be stopped by pressing the push button switch SW8. Similarly, by operating the push button switch SW3, the light emitting diode LED3 and the solenoid valve SV3 are operated, and the hot water can be discharged from the pouring gate 19, and the water discharge can be stopped by operating the push button switch SW8.

Further, by operating the push button switch SW4, the light emitting diode LED4 and the solenoid valve SV4 are operated to discharge water from the hand shower 20, and by operating the push button switch SW5, the light emitting diode LED5 and the solenoid valve SV5 are operated, and the body showers 21 and 21 are operated. Push button switch S
Water can be stopped by W8. If the battery voltage is low during the above operation, the light emitting diode LED8 blinks similarly. Further, the push button switches SW1 to SW5
When the other pushbutton switches SW1 to SW5 are operated without pressing the pushbutton switch SW8 during the operation of, the operation performed thereafter has priority and the water discharge state can be switched. Further, the duplicate operation of the same switch is invalidated.

FIG. 11 shows a timing chart when the push button switch SW6 is operated. Push button switch SW6
As soon as the button is pressed, the light emitting diode LED6 is turned on. However, a timer built in the control unit 26 is operated, and after 5 seconds, the solenoid valve SV6 is opened, and hot water is sprayed from the floor watering nozzle 22 . The floor watering nozzle 22 is used to warm the floor surface by watering before using the bathroom, so that the clothes and feet of the operator do not get wet due to sudden watering. Time is set. In the same manner, the floor water can be automatically stopped for 10 minutes by a timer, or can be arbitrarily stopped by operating the push button switch SW8. When the push-button switch SW6 is operated while the solenoid valves SV1 to SV5 are being opened, this floor sprinkling has priority.

FIG. 12 is a timing chart when an abnormal signal is obtained from the thermistor 15. For example, when the thermistor 15 outputs a signal such as a high temperature detection or a disconnection during the opening operation of the solenoid valve SV1, after the abnormal signal continues for 3 seconds (a timer count is performed to eliminate an instantaneous one due to the pulsation of the hot and cold water temperature). In order to determine the persistence of the abnormal state, the light emitting diode LED8 is turned on to indicate the occurrence of the abnormality and the solenoid valve SV1 is closed. At this time, any one of the push button switches SW1 to SW7 cannot be input. When the abnormality signal is stopped, the light emitting diode LED8 is turned off after the persistence is confirmed by the timer count for 5 seconds. In addition, when there is no persistence for more than 5 seconds both when the abnormal signal is generated and when the abnormal signal is stopped, the state is continued as it is. In this way, the abnormality signal obtained from the thermistor 15 is confirmed to have its continuity by the timer count, and then the abnormality display and the emergency closing or the cancellation are performed.

FIG. 13 shows a push button switch SW for draining water.
7 is a timing chart showing the operation of pressing all the solenoid valves 7 to open all the solenoid valves SV1 to SV6. When the push button switch SW7 is operated, the solenoid valve SV1 is opened first, and 50 ms later, the solenoid valve SV2 is opened.
After milliseconds, the solenoid valve SV3 opens, after another 50 milliseconds the solenoid valve SV4, after another 50 milliseconds the solenoid valve SV5,
Further, after 50 milliseconds, the solenoid valve SV6 is opened. Then, the light emitting diode LED7 blinks to indicate that water is being drained, and then, for example, after elapse of 10 minutes necessary for draining, the solenoid valves SV1 to SV6 are sequentially arranged at intervals of 20 milliseconds in order from the solenoid valve SV1 to the solenoid valve SV6. Close the valve. The valve closing operation can be arbitrarily performed by the push button switch SW8. In addition, another solenoid valve SV1
This drainage is prioritized even when .about.SV6 is open. The operation of other switches is not accepted during draining.

As described above, all the solenoid valves SV1 for draining water are used.
When a command signal for opening or closing the solenoid valve SV6 is issued, the solenoid valves are sequentially operated with a time difference equal to or longer than the required operation time of each solenoid valve. This prevents an excessive load from being applied to the power supply battery at one time. The time difference when the valve is opened is 50 milliseconds, and the time difference when the valve is closed is 2
The reason why the set time difference is set to 0 ms when the valve is opened and when the valve is closed is that the required operating time of the latching type solenoid valve used here is different between when the valve is opened and when the valve is closed.
In this way, by setting the time longer than the required operation time in consideration of the required operation time of the solenoid valve in consideration of the time difference, it is possible to prevent a drive current from being required simultaneously for two or more solenoid valves.

The light emitting diodes LED1 to LED5
Since the switches SW1 to SW5 are displayed for facilitating confirmation that the push button operation has been performed, the lighting time of each is suppressed to 5 seconds, thereby preventing unnecessary consumption of the battery. The lighting time of the light emitting diode LED6 when the push button switch SW6 is operated is set to be 10 seconds. Further, the continuous lighting time and the blinking time of the light emitting diode LED8 are also set not to exceed 10 minutes, so that useless battery consumption is prevented. This multi-function shower is powered by batteries,
It does not require wiring work when installed in a bathroom or the like, is easy to install, and can be used safely without fear of electric leakage.

Further, in this embodiment, the temperature of the hot water is controlled by the temperature control knob 12 of the hot-water mixing faucet with thermostat 10, but a temperature control section is provided in the control box 55 as shown in FIG. Then, the control motor of the hot-water mixing faucet with thermostat 10 may be operated by the temperature command 90 to adjust the temperature in the multifunctional shower unit.

In this embodiment, the floor sprinkler nozzle 22
Although the bathroom floor can be heated by the hot water that is blown out, the bathroom can be heated by spraying hot water by discharging hot water from the top shower 18, the pouring gate 19, the hand shower 20, or the body showers 21 and 21. It is possible, and any point may be used as long as it is a spout provided toward the bathroom floor. Further, in this embodiment, the multifunctional shower apparatus having a plurality of spouts has been described. However, it is needless to say that an apparatus having only one spout can be used.
