When the wing nut 87 is tightened, the cap 88 is removed and the fingers are put in the case 29 for operation. I am able to do it.

In the multifunctional shower device configured as described above, as shown in the 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 SV1 is opened. The diode LE D1 turns off after 5 seconds. When the solenoid valve SV1 is opened, hot water is sprayed in a mist form from the mist showers 17, 17 and the spray is stopped by pressing the push button switch SW8. When the voltage of the dry battery set in the battery box 56 becomes 4.5 V or less, 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, hot water is jetted from the top shower 18, and the push button switch SW8 can be stopped. Similarly, by operating the push button switch SW3, the light emitting diode LED3 and the solenoid valve SV3 are operated, hot water can be discharged from the pouring gate 19, and by operating the push button switch SW8, the water discharge can be stopped.

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 shower 21, Water can be discharged from 21 and can be stopped by the push button switch SW8. If the battery voltage is low during the above operation, the light emitting diode LED8 also blinks. Further, when the other push button switches SW1 to SW5 are operated without pushing the push button switch SW8 while the push button switches SW1 to SW5 are being operated, the operation subsequently performed can be prioritized to switch the water discharge state. In addition, double-recovery operation of the same switch is invalid.

FIG. 11 shows a timing chart when the push button switch SW6 is operated. The light emitting diode LED6 lights up immediately when the push button switch SW6 is pressed, but the timer built in the control unit 26 operates and the solenoid valve SV6 opens after 5 seconds, and hot water is sprayed from the floor hot water shower 22. . Since this floor sparing shower 22 is for warming the floor surface in advance by using the sparing water before using it in the bathroom, in order to prevent the operator's clothes and feet from getting wet with the sudden sprinkling water, There is a grace period. In the same way, this floor spraying can be stopped automatically by a timer within 10 minutes, or can be stopped by operating the push button switch SW8. Further, when the push button switch SW6 is operated while the solenoid valves SV1 to SV5 are in the opening operation, this floor hot water is prioritized.

FIG. 12 shows a timing chart when an abnormal signal is obtained from the thermistor 15. For example, when the thermistor 15 outputs a signal such as high temperature detection or disconnection during the opening operation of the solenoid valve SV1, the abnormal signal continues for 3 seconds (timer count to eliminate momentary ones due to pulsation of hot and cold water temperature). In order to determine the continuity of the abnormal condition, the light emitting diode LED8 is turned on to indicate the occurrence of the abnormal condition and the solenoid valve SV1 is closed. At this time, none of the push button switches SW1 to SW7 can be input. When the abnormal signal is stopped, the light emitting diode LED8 is turned off after the continuity is confirmed by the timer count for 5 seconds. If there is no persistence of 5 seconds or more both when the abnormal signal is generated and when the abnormal signal is stopped, the state is maintained as it is. As described above, the abnormality signal obtained from the thermistor 15 is displayed on the abnormality and the emergency closed or released after the continuity is confirmed by the timer count.

FIG. 13 shows a timing chart when the push button switch SW7 is pressed to drain water and all the solenoid valves SV1 to SV6 are opened. When the push button switch SW 7 is operated, the solenoid valve SV1 is first opened, then 50 ms later, the solenoid valve SV2 is opened, 50 ms later, the solenoid valve SV3 is opened, and 50 ms later. The solenoid valve SV4, the solenoid valve SV5 after 50 milliseconds, and the solenoid valve SV6 after 50 milliseconds are opened. Then, the light emitting diode LED7 blinks to indicate that water is being drained, and after the elapse of 10 minutes required for draining water, the solenoid valve SV1 to the solenoid valve SV6 are automatically arranged at intervals of 20 milliseconds each in order. Close the valve. It should be noted that this valve closing operation can be arbitrarily performed by the push button switch SW8. Further, even when the other solenoid valves SV1 to SV6 are opened, this drainage is prioritized. Then, while the water is being drained, the operation of other switches is not accepted.

As described above, when issuing command signals for opening or closing all the solenoid valves SV1 to SV6 for draining water, the solenoid valves SV1 to SV6 are sequentially operated with a time difference of a required operation time or more. I have to. This prevents the battery from being overloaded at one time. The time difference when opening the valve was set to 50 ms, the time difference when closing the valve was set to 20 ms, and the set time difference was different between when the valve was opened and when it was closed. This is because the required operating time of the valve is different when the valve is open and when it is closed. In this way, by considering the above-mentioned time difference and considering the required operation time of the solenoid valve and setting it to be longer than the required operation time, it is possible to prevent the drive current from being required for two or more solenoid valves at the same time. To do.

Since the light emitting diodes LED1 to LED5 are displayed in order to make it easy to confirm that the switches SW1 to SW5 have been pressed, the lighting time is suppressed to 5 seconds. This prevents unnecessary battery consumption. Further, 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 flashing time of the light emitting diode LED8 are set not to exceed 10 minutes to prevent wasteful battery consumption. Since this multi-function shower is driven by dry batteries, it does not require wiring work when installed in a bathroom, etc. It is easy to install and can be used safely without the risk of electrical leakage.

In this embodiment, the temperature of the hot water is controlled by the temperature adjusting knob 12 of the hot and cold water mixing faucet 10 with a thermostat, but a temperature adjusting section is provided in the control box 55, as shown in FIG. As described above, the temperature command 90 may be used to operate the control motor of the hot water / water mixing faucet with thermostat 10 to adjust the temperature in this multifunctional shower unit.

In this embodiment, the bathroom floor can be heated by the hot and cold water sprayed from the floor hot water shower 22. However, the bathroom is heated by such hot water spraying as the top shower 18, the hot water spout 19, and the hand. It is also possible to discharge hot water from the shower 20 or the body showers 21 and 21, and any point may be used as long as it is a sprinkling port arranged toward the bathroom floor. Further, this embodiment has explained the multifunctional shower device having a plurality of sprinkler ports, but it goes without saying that a device having only one sprinkler port can also be applied.

[0032]

[Effect of device]

 As described above, in the bathroom hot water sprinkler of the present invention, the solenoid valve is opened after a certain period of time without immediately sprinkling hot water even if the switch is opened, because the controller has the valve opening delay timer. Since it is sprinkled with hot water, you can get out of the bathroom without getting your clothes and feet wet even if you enter the bathroom with your clothes on before you take a bath and you can heat the bathroom floor comfortably. You can In addition, since the solenoid valve and all the functions such as the control section and the operation section are provided in the waterproof case, there is no need for electrical work just by installing them in the bath room, and therefore there is a risk of water leakage or electric leakage. In addition, it has a beneficial effect that it can be installed at low cost and can be used safely.
