摘要： PURPOSE:To prevent water hammer by a method wherein the flow rate control valve of a hot-water supplying machine is driven into closing direction to choke the flow rate to a predetermined flow rate when a hot-water supplying cock is not used by the decision of a hot-water using deciding means while the automatic hot-water supplying valve is closed after detecting the predetermined flow rate. CONSTITUTION:When automatic hot-water supply is finished, a hot-water supplying cock is judged by a hot-water supplying cock using condition deciding means 28 whether it is being used or not at first and when it is not being used, a flow rate control means 24 drives a flow rate control valve 9 into the closing direction thereof through a flow rate control valve driving means 26. Next, the flow rate control valve 9 is judged by a position detecting switch and the like whether the same is fully closed or not. When the valve 9 is not closed fully, the valve 9 is closed gradually and after the predetermined flow rate is detected, the automatic hot-water supplying valve 21 is closed. The automatic hot-water supplying valve 21 is closed after the flow rate control valve 9 is choked in such a manner whereby the generation of water hammer becomes hard.

摘要： PURPOSE:To enable an efficient automatic hot water supply operation for a a bath tub placed at the second floor to be carried out by a method wherein a hot water supply device for the bath tub comprises of an automatic hot water supply circuit having an automatic hot water supply opening or closing valve, a water supply part and a check valve, and a control means for instructing an opening of a hopper valve and a water discharging at a time of sensing a predetermined water level of a water level sensor after supplying hot water to the bath tub. CONSTITUTION:As an automatic hot water supply switch 28 is turned ON, an automatic hot water supply opening or closing valve 10 is opened. Hot water heated by a hot water supply heat exchanger 7 passes through a check valve 36 and flows into a water receiving pan 24a, an amount of receiving water in a water receiving pan 24a is increased to compress a spring 24c and then a hopper valve 24 is pushed down to close a valve seat 24b. Then, the hot water passed through a water passing part 22 flows from a check valve 37 to a bath tub 19 through an additional heating heat exchanger 16. A water level (pressure) of the fed hot water is detected by a water level sensor 23 through a return pipe 21 and this is transmitted to a control means 26. The control means 26 compares it with a water level set by a water level setting device 29 of a controller 27 and supplies automatically the hot water up to its set water level. After supplying hot water, water leaked out of the hopper valve 24 reaches an ON state sensing water level of a water level electrode 25, the control means 26 changes over a three-way changing-over valve 13, operates a pump 14 and discharges the water stored in the discharging part 20 into the bath tub 19 and recovers it.

摘要： PURPOSE:To prevent uselessly disposing of hot water from a hopper even when a large amount of hot water is used at other places during automatic water supplying operation by a method wherein the automatic water supply is interrupted temporarily when an automatic water supplying flow rate drops down below a set value, and when an interruption reason is removed, the automatic water supply is continued successively. CONSTITUTION:When a hot water supply valve is opened, hot water heated by a hot water supply heat exchanger 1 is supplied through a hopper 8 and a circulation passage into a bath tub 5, and when water in the bath tub 5 reaches a proper temperature and a proper volume, the hot water supply valve 6 is closed to end an automatic water supply operation. In this instance, if a hot water supply tap 4 is opened during the automatic water supply and used water volume on the water supply tap 4 side is so large that water volume flowing to the hopper 8 side drops down below a prescribed value, a flow rate switch 12 detects an OFF flow rate, and a valve 7 is opened while the hot water supply valve 6 is closed so that the automatic hot water supply is made to stand by. After that, when the use of water through the hot water tap 4 is finished and the tap 4 is closed, a flow rate sensor 2 detects OFF to open again the hot water supply valve 6 to restart the automatic water supply. If the water supplied into the bath tub 5 reaches a proper temperature and a proper volume, a hot water supplying operation is stopped.
