ら構成される。 The water flow signal generators 12, 13, explained in FIG.
14 all have the same structure, an example of which will be explained using the water flow signal generator 26 in FIG. The water flow signal generator 26 operates the water flow signal generator after opening each hot water tap 2, 3, 4 and setting the hot water temperature using a remote control device 27 having the same structure as the remote control devices 15, 16, 17 shown in FIG. When the setting switch 20 for this purpose is turned on, a water flow signal is generated. In synchronization with the signal from the setting switch 20, the hot water temperature setting value of the remote controller 27 and the address value set by the address switch 25 are read. The read signal is converted into a signal by the control unit 21, and is built into a timer 22 that operates according to the converted signal, a valve drive unit 23 that turns on and off the water flow according to the timer, and a water flow signal generator 26. installed in the hot water piping leading to each hot water tap,
It is comprised of (water flow valve) 24 that cuts off and on the supply of hot water from each hot water tap.

くてもよい。 FIG. 4 shows an example of a water flow signal waveform.
The vertical axis represents flow rate and the horizontal axis represents time. Time A
The setting switch on the remote control device is turned on at the point.
In synchronization with this signal, the valve closes for a time corresponding to a predetermined address value, reducing the amount of water. The time width Z 1 during which the amount of water is decreasing indicates the address. After this, the valve is opened for a certain period of time and the water flow increases. At time B, the valve is closed for a time period Z 2 corresponding to the hot water temperature setting value to reduce the amount of water. This water amount change is communicated to the main body through the hot water supply piping and is transmitted to the water amount sensor 7'. The control circuit 8 is
Measure the differential value of the water amount sensor value,
Eliminates malfunctions. In this embodiment, data is transferred based on the width of the water flow pulse (increase/decrease in water flow caused by opening and closing of a valve), but the data may be transferred after converting the number of water flow pulses or the water flow pulse amplitude. Also, regarding the timing of water flow signal generation at time point A,
Since it is synchronized with the setting switch 20, there is no need to generate a timing signal by, for example, stopping hot water supply.

は問題にならない。 Next, in the case of simultaneous hot water supply, for example in Fig. 2,
If a shower is used while hot water is being supplied in the kitchen, there is a problem as to which setting should be used. Therefore, a unique hot water supply address is set for each using the address switch 25, the addresses are compared, and the hot water temperature is set according to the priority order. Here, the address switch is provided on the remote control device or the water flow signal generator so that it can be freely changed using the switch, so that addresses can be easily assigned when expanding the number of units. The value detected by the water flow sensor is measured as a differential value, so the flow rate does not matter.
