る蓄熱形電気温水器に関する。[Detailed Description of the Invention] [Technical Field of the Invention] This invention relates to a regenerative electric water heater used for supplying hot water to bathrooms, kitchens, etc.

As seen in Utility Model Publication No. 41-9835, this type of electric water heater is equipped with a heat storage device, and the heater of the heat storage device is energized using inexpensive late-night electricity to store heat. There are known devices that use heat to heat the water in the tank to keep it warm.

してしまうことになり、経済的に大きな損失を招
いてしまう結果となる。 By the way, the amount of hot water consumed in a typical household varies greatly depending on the season, such as winter or summer, or the number of members of the family. However, in the case of electric water heaters as mentioned above, the hot water in the tank is simply kept warm by simply bringing a part of the heat storage device into contact with the tank, so the amount of hot water that can be used is limited to the amount in the tank. The amount of hot water stored in the water is limited. If you adjust the volume of the tank to the maximum amount of hot water consumed, you can cover the required amount with the hot water stored in the tank.
However, in such cases, electric water heaters are large and disadvantageous in terms of installation and transportation, and the season changes from winter when hot water consumption is high to summer when hot water consumption is low, or when the number of family members increases. If the amount decreases, more water than necessary will be boiled unnecessarily, resulting in a large economic loss.

に構成することも可能である。 First, the changeover switch 16 is closed during seasons when the amount of hot water consumed is high, such as in winter. Then, water from the water source 10 is supplied from the water supply pipe 11 through the introduction path 13 into the tank 2 until the tank 2 is full of water, and in this state, the operation switch 22 is turned on. Then, at night, the water heater 4 and the thermal storage heater 8 are energized by the midnight electric power source 15 to generate heat, and the water in the tank 2 is boiled to a high temperature of, for example, 85°C.
It stores heat at several times the temperature of the hot water inside, or around 200 to 500 degrees Celsius. Then, when the temperature of the heat storage device 3 reaches the set temperature, the thermostat 17 senses it and closes its contacts, and accordingly, the relay 18 is energized, and its contact mechanism 20 operates to drive the three-way valve 12. The circuit 21 is closed, and the three-way valve 12 is in a state where the water supply pipe 11 communicates with the heating path 9.
is operated automatically. In addition, this three-way valve 12
It is also possible to configure the system so that it can be operated manually after a power outage in the middle of the night.

お、蓄熱器3での湯の沸しは、蓄熱器3が一定温
度に降下するまで継続することができる。 For example, the next morning, the hot water supply valve 7
When opened, the hot water in the tank 2 sequentially flows out through the hot water supply pipe 5 based on the water pressure from the water source 10 and is supplied to the bathroom, kitchen, etc. Also at this time, the water supply pipe 11
Water from the water source 10 sequentially flows into the heating path 9 through the heating path 9 . While flowing through the heating path 9, this water is heated by the heat stored in the heat storage device 3, that is, it exchanges heat with the heat storage device 3, and becomes hot water at a temperature similar to that of the hot water in the tank 2, and is then introduced. It drains into tank 2 through channel 13. Therefore, the total amount including not only the hot water previously stored in the tank 2 but also the hot water boiled in the heat storage device 3 can be supplied to the bathroom and the kitchen. Note that boiling of water in the heat storage device 3 can be continued until the temperature of the heat storage device 3 drops to a constant temperature.

となく、経済的な運転を達成することができる。 On the other hand, during seasons such as summer when the amount of hot water consumed is low, the changeover switch 16 is left open and the operation switch 22 is turned on in this state. In such a case, only the water heater 4 is energized, so that only the water in the tank 2 is boiled. Further, since the heat storage heater 8 does not generate heat, the contacts of the thermostat 17 remain open, and the three-way valve 12 is maintained in a state in which the water supply pipe 11 is communicated with the tank 2 side. When the hot water supply valve 7 is opened in this state, the hot water in the tank 2 sequentially flows out through the hot water supply pipe 5, and in conjunction with this, water from the water source 10 flows into the tank 2 from the water supply pipe 11 through the introduction path 13. Therefore, in this case, hot water can be effectively supplied using only the hot water stored in the tank 2, as originally planned. In this case, the thermal storage heater 8
Since the power supply to the boiler is omitted, economical operation can be achieved without boiling water unnecessarily.

The heating path 9 is directly connected to the hot water supply pipe 5 via a bypass path 25 without passing through the tank 2.

も可能である。 In such a configuration, as mentioned above, the water heater 4 is
The heat storage heaters 8 and 8 are respectively energized to boil water in the tank 2 and store heat in the heat storage device 3. After that, operate the three-way valve 12 so that the water supply pipe 11 communicates with the tank 2 side, and in this state, the hot water supply valve 7
is opened, and the hot water in the tank 2 is allowed to flow out through the hot water supply pipe 5. After almost all of the hot water in the tank 2 has flowed out, the three-way valve 12 is operated to open the water supply pipe 11.
is communicated with the heating path 9. Water source 10 according to this
Water flows into the heating path 9 from the water supply pipe 11, is heated by the heat of the heat storage device 3, becomes hot water, and this hot water flows out from the hot water supply pipe 5 through the bypass path 25. Therefore, a large amount of hot water can be supplied using the hot water in the tank 2 and the hot water boiled in the heat storage device 3. Note that when the hot water in the tank 2 flows out and water from the water source flows into the lower part of the tank 2, a boundary between a high temperature layer and a low temperature layer is created in the tank 2, and this boundary rises as the hot water flows out. Therefore, a temperature sensor is installed on the wall of the tank 2, and this temperature sensor detects the rise in the boundary and detects the point when almost all of the hot water in the tank 2 has flowed out. It is also possible to automatically control the three-way valve 12 so that 11 communicates with the heating path 9.

The three-way valve 12 is operated to connect the water supply pipe 11 to the tank 2 side, and in this state, only the water heater 4 is energized in the same manner as described above. This causes tank 2
You can boil water and supply it economically.

る。 FIG. 4 shows a third embodiment, in which an intake port 31 is formed on one side of the heat insulating casing 1, and an exhaust port 32 is formed on the other side facing the heat storage device 3, and further facing the exhaust port 32. When the fan 33 is driven, air flows in from the intake port 31, this air passes around the heat storage device 3, and during this time, the air is heated by the heat of the heat storage device 3. This hot air is made to flow out from the exhaust port 32 and can be used to heat the room.

As explained above, according to this invention, there is no need to make the tank unnecessarily large, and a heat accumulator that stores heat higher than the water temperature in the tank is attached, and the volume occupied by this heat accumulator is larger than necessary. Since the hot water can be replenishably selectively used, it is possible to economically boil and supply the necessary amount of hot water corresponding to the season, etc., without waste.
