問題があつた。[Problem to be solved by the invention] However, in the hot water mixing device described above, if a power outage occurs while only water or hot water is being used due to the operation of the controller, the hot water mixing valve will not turn off the water or hot water. One side of the hot water passage remains completely closed, and water can be drained from the other unclosed passage by operating a drain valve or air charge valve, but the valve on the side of the passage with the valve completely closed remains. Because the water or hot water cannot be drained, it stagnates, and the antifreeze heater cannot be operated due to a power outage.
Particularly in cold regions, there is a problem that water or hot water that remains on the side of the passageway where the valve is completely closed may freeze.

As shown in FIG. 5, the hot water mixing device 10
It is installed through a solenoid valve 201 in the bathtub hot water supply piping system 13 connected to the third hot water outlet 122 of , an inner cylinder 203 facing the bathtub hot water supply piping system 13, and this inner cylinder 203.
It has a double cylindrical shape with an outer cylinder 204 provided around the outer cylinder 204, and hot water H/W is sent from the lower end opening 204a of the outer cylinder 204 to an outgoing circulation path 301 facing into the bathtub A of the heat retention unit 300, which will be described later. It is now possible to supply hot water. In addition, 205 in the figure is the outer cylinder 204.
This is a drain pipe connected to the upper end of the drain pipe.

に設置可能にしてなるものである。 The automatic hot water supply unit 200 always positions the lower end opening of the inner cylinder 203 constituting the double cylindrical water receiving hopper 202 below the water level L in the bathtub A, thereby supplying hot water for the bathtub. Even if hot water H/W is supplied from the piping system 13 to the upper water receiving part of the inner cylinder 203, the water level fluctuation is absorbed by the double cylindrical water receiving hopper 202, and the influence of the water level fluctuation at the water level to be detected is eliminated. This makes it possible to accurately detect the water level in the bathtub A without being exposed to water. Further, as shown in FIGS. 6 and 7, the automatic hot water supply unit 200 has side wall surfaces of the bathrooms U and B in an outer space G that is formed to protrude inward, for example, in a V-shaped cross section. This makes it possible to fit the bathroom without reducing the available space, which is limited.
The water receiving hopper 202 can be easily installed at a higher position than the bathtub A.

It has a configuration in which an outgoing circulation path 301 and a return circulation path 302 are faced, and a circulation pump 303 and a heat exchange tank 304 are arranged on this circulation path, and the heat exchange tank 304 has a heating A heater 305, an air vent valve 306, a float switch 307, and a thermistor 308 are installed, and when the pressure sensor 309 installed in the recirculation path 302 detects the set water level L for hot water supply to the bathtub A, the automatic hot water supply unit The solenoid valve 201 of 200 is closed to stop supplying hot water, and the water heater 1 is also controlled to stop operation, and at the same time, the circulation pump 303 is driven to drain the water inside the bathtub A. The bath water in the bathtub A is forcedly circulated, and the forcedly circulated bath water is appropriately heated by the heater 305 of the heat exchange tank 304, thereby keeping the bath water in the bathtub A at a desired temperature at all times. It's becoming like that.

て、水通路１１６に水が滞留し、寒冷地では凍結
事故の原因となる。 As shown in FIG. 3, in the hot water mixing device 100, for example, when only hot water H/W is used, the water passage 116 is completely closed by the hot water mixing valve 117, and a power outage occurs at this time. Then, the stepping motor, which is the controller 118 that drives the hot water mixing valve 117, remains stopped at that position. In this state, when the drain valves 51, 52 and the air charge valve 53 are operated, water can be drained from the hot water passage 115 which is not closed, but air is not supplied to the water passage 116 which is closed. As a result, water cannot be drained, which causes water to accumulate in the water passage 116 and cause freezing accidents in cold regions.

栓から外部に流出させることが可能になる。 Therefore, in the hot water supply system according to this invention, when the power is re-energized after a power outage, the controller 118
By driving the stepping motor according to the step value, the hot water mixing valve 117 is operated as the second stepping motor.
Initialize by returning to the mixing intermediate position as shown in the figure.
This provides an antifreeze function that controls water drainage by opening each passage 115, 116. Especially in cold regions, if a power outage occurs, freezing will be prevented. Since the prevention heater 123 will no longer operate, immediately operate the drain valves 51 and 52 and manually operate the check valves 107 and 107 using the first and second valve push rods 103 and 104.
By pushing up 108 to open each passage, water can be immediately drained from the drain plugs 51 and 52, and freezing accidents can be prevented. In addition, if the drain valves 51 and 52 are operated and the hot water mixing valve 117 closes one of the passages and there is water remaining in the passage, the hot water mixing valve 117 is moved to the mixing intermediate position by reenergizing. When the water returns to normal, the passage opens and the accumulated water can flow out from the drain valve, which is now open.

のである。[Effects of the invention] As is clear from the above explanation, according to this invention, the pressure of the water and hot water supplied from the primary side is regulated through the pressure regulating valve provided on the secondary side, and these water and hot water are In a hot water mixing device in which the hot water mixing ratio is variably adjusted by a hot water mixing valve that is electrically driven and controlled by a controller to control the temperature and discharge hot water from a hot water outlet, the controller is connected to a power source that is once cut off. When the water is reenergized, the hot water mixing valve is initialized to the intermediate mixing position, so that the water and hot water passages are opened and the water is drained when the electric power is reenergized. This has the excellent effect of reliably preventing freezing accidents from occurring.
