のであつた。(Conventional technology and problems) Conventionally, in systems that supply hot water into a hopper and send the liquid from the hopper to another location using a pump,
Water flow was controlled using ball taps and sensors that detected the upper and lower limits of water level. However, the flow rate supplied to the hopper and the flow rate discharged from the hopper did not match, and both supply and discharge were controlled by ON-OFF control, and valves and pumps were frequently turned ON-OFF.

目的とする。 The object of the present invention is to eliminate the above-mentioned conventional drawbacks and to perform stable liquid feeding by matching the flow rates into and out of the hopper.

う。 Next, the operation of the above configuration will be explained using FIGS. 2 and 3. Water entering from the water inlet pipe 3 is heated by a hot water supply heat exchanger 1 whose capacity is controlled by a temperature sensor 4 and a water flow rate sensor 5, and is sent to a hot water supply pipe 10 and a bath water supply pipe 13. Now, start dropping it into the bathtub. (FIG. 2A), the solenoid valve 11 is opened (FIG. 2B), and hot water flows into the hopper 12. When the water level rises and the water level switch L3 is turned ON at time t1 shown in FIG. 3, the three-way valve 19 is switched to communicate the connecting pipe 18 with the suction port of the circulation pump 16 (FIG. 2C). At the same time, the circulation pump 16
(Fig. 2D). Assuming that the supply flow rate from the bath water supply pipe 13 to the hopper 12 is q1, and the flow rate of the circulation pump 16 is q2, if q1 > q2, the water level will further rise as shown in Fig. 3, and the time t 2
When water level switch L1 turns ON, water flow control valve 6
Start narrowing down (Fig. 2 E). If the throttle is continued further, the water level switch L1 will be turned OFF at time t3 shown in FIG. At this time, the timer in the controller 21 is activated (FIG. 2F), and at the same time, the operation of the water flow control valve 6 is stopped (FIG. 2G). When the water level further decreases and the water level switch L2 turns OFF at time t4 shown in Fig. 3, the timer is stopped (Fig. 2 H). Setting the time from L1 to L2 as Tn , the controller 21 calculates the water amount difference (q2-q1) as q2-q1=V/ Tn (FIG. 2 I). Incidentally, V is the volume of the hopper from water level switch L1 to L2. Then, the water flow control valve 6 is opened by the calculated water flow difference (FIG. 2J) to match the water flow into and out of the hopper 12 (as shown by the water flow after time t5 shown in FIG. 3). q1＜q2
In this case, water level switch L3 is turned OFF, so
At this time, open the water flow valve 6 (Fig. 2 K) and increase the inflow amount so that the water level switch L3 is turned ON again. When the water level switch L3 turns ON, the water flow valve 6 is stopped (Fig. 2 L) Then, the same control as when q1>q2, that is, the control from FIG. 2 E to FIG. 2 J is performed.
尚、水位スイツチＬ１ON後水量弁６を絞つて
も一定時間内にOFFしなければ電磁弁１１を閉
じ、水位スイツチＬ３OFF後一定時間内にONし
なけれは循環ポンプ１６をOFFする（第２図Ｎ）
ようになつている。落とし込み終了時は電磁弁１
１閉後一定時間たつて循環ポンプ１６をOFFす
ることにより、ホツパ１２内を空にしておく。 Furthermore, if the water level switch L1 does not turn off within a certain period of time even if the water volume valve 6 is throttled down after turning on, the solenoid valve 11 will be closed, and if the water level switch L3 does not turn on within a certain period of time after turning off, the circulation pump 16 will turn off (Fig. 2 N )
It's becoming like that. At the end of dropping, solenoid valve 1
The inside of the hopper 12 is emptied by turning off the circulation pump 16 after a certain period of time after the first closing.

ならず、その分時間がかかるのである。(Effects of the invention) As described above, the invention provides a water flow sensor and a water flow control valve in this order in the hot water supply path to the hopper.
In the case where liquid is sent from the hopper by a pump, three water level switches are installed in the hopper at the top and bottom, and the difference in the flow rate in and out of the hopper is calculated based on the time difference between the signal outputs of the two water level switches, and the current flow rate is calculated. Since the water flow control valve is controlled so that the water flow rate sensor detects the flow rate including this flow rate difference, the flow rate in and out of the hopper can be matched to provide stable liquid delivery, and the frequency of turning on and off the valves and pumps is reduced. It is something. Also, the response speed is faster than the one with two water level switches. In other words, in the case of two switches, even if you calculate the time difference from the upper limit switch to the lower limit switch, in order to reach the appropriate water level, you must flow a flow rate that is greater than the flow rate difference to once raise the water level to the lower limit switch or higher, and the time will be reduced accordingly. It takes a lot of money.
