湯切れは良くなる。The operation of water heating and water supply will now be described. Hot water heated in the water storage container 2, for example, 90 to 95 ° C.
Hot water is discharged from the tap hole 6 by the pump 17, and the water level in the water storage container 2 decreases. This is detected by the water level detecting means 22 provided in the water storage container 2, and based on the result, the switching valve 13 is opened to the water supply port 11 side and the water stop valve 10 is opened to start water supply. This water supply amount is measured by the flow meter 23, and when a predetermined water supply amount is reached, the water stop valve 10 is closed. The water discharged from the water supply port 11 is temporarily stored in a water supply tray 24 provided in the water storage container 2 first. The stored water is guided to the vicinity of the bottom of the water storage container 2 by a drip pipe 25 provided on the bottom surface of the water supply tray 24. The introduced water does not mix with the existing hot water in the water storage container 2 due to a difference in specific gravity, stays in the separated state near the bottom of the water storage container 2, and is heated by the heater until it becomes hot water. At this time, the water intake 16 is installed at a position corresponding to the amount of water supplied into the water storage container 2 at a time, that is, above the upper limit position of water staying near the bottom of the water storage container 2. No water is taken out. Therefore, only hot water is discharged from the tap 6 at any time. Further, since the water in the water storage container 2 is heated in the space opened to the atmosphere, the pressure hardly increases, and
Hot water does not erupt. Also, only the hot water of the same height as the water level in the water storage container 2 remains in the water channel connecting the tap hole 6 and the water storage container 2, and the heat radiation in the water channel is extremely small. Can be put out. Further, since the tapping-type tapping water is supplied by the pump 17, a predetermined tapping flow rate can be obtained regardless of a change in tap water pressure. In addition, the shortage of the hot water when the hot water is stopped is improved due to the short water path from the pump to the tap hole and the large water head pressure in the water path due to the water in the water reservoir 2 being released to the atmosphere. .

At this time, the water in the water storage container 2 overflows from the opening 21 to the outside of the water storage container 2, and the space distance between the water surface in the water storage container 2 and the water supply port 11 is maintained at a certain value or more. Therefore, even if the inside of the water pipe 1 becomes negative pressure for some reason and the check valve 34 does not function, the water in the water storage container 2 does not flow back to the water pipe 1. Reference numeral 27 shown in the figure is a valve which is easily opened by the pressure of overflowing water, and normally prevents steam from leaking out of the water storage container 2 in a closed state.

When the water stop valve 10 causes water stoppage failure and water is continuously supplied into the water storage container 2, the water level in the water storage container 2 exceeds the water supply stop water level m and reaches the rising water level n. Here, the control circuit stops the heater input based on the output of the water level detecting means 22, and stops heating the water in the water storage container. With continuous water supply, the water level rises further and eventually reaches the water level k. When the water level detecting means 22 detects the water level k, the pump 17 is operated by the control circuit, and the water storage container 2
The water inside is drained from the tap 6 to the kitchen sink 20. At this time, since the temperature of the hot water in the water storage container that has been heated in advance is lowered by continuous water supply, the hot water can be safely discharged even when the user is working around the kitchen sink. Further, since the amount of water supplied from the water supply port 11 is smaller than the amount of water discharged to the outside by the pump 17, the water does not overflow from the opening 21 to the outside of the water storage container 2. Therefore, damage to the periphery of the kitchen can be eliminated. The drainage temperature can be adjusted by the ratio of the distance between the rising water level n and the water level k and the distance between the rising water level n and the bottom of the container.

When the water supply further proceeds, the water flows into the kitchen sink 20 from the overflow channel 33 provided in the water receiving portion 31, and the water level in the water receiving portion 31 is eventually stabilized. At this time, the spatial distance between the second water outlet 30 and the water surface in the water receiver 31 is maintained at a certain value or more. Therefore, even if the inside of the water pipe 1 becomes a negative pressure state for some reason and the check valve does not function, the water in the water storage container 2 does not flow back to the water pipe 1.
