[Effect of device]

 As described above, the hot water / chiller raw water boiling apparatus of the present invention stores the raw water directly or indirectly supplied from the tap water, etc. and the water storage tank 2 inside the water storage tank 2. It consists of a boiling heater 5 for boiling the raw water A little by little, and a hot water tank 8 for storing the hot water boiled by the boiling heater 5. The boiling water is put between the water tank 2 and the boiling heater 5. By connecting the check valve 7 which prevents the hot water obtained by boiling the raw water A in the water storage tank 2 little by little with the heater 5 to return to the water storage tank 2 side, when using, the inside of the water storage tank 2 The raw water A is boiled little by little with the boiling heater 5, and the boiling water boiled here tries to expand. However, the check valve 7 does not return the boiling water to the water storage tank 2 side, and it boil without the pump. The pressure rises against gravity to the side of the hot water tank 8 and flows into the hot water tank 8.

That is, since the raw water A in the water storage tank 2 can be boiled little by little by the boiling heater 5 and the hot water can be stored in the hot water tank 8, the raw water in the hot water tank can be stored as in the conventional case. Not only can the hot water in the hot water tank 8 be provided more quickly than the one that is collectively heated, but the boiling water heater 5 between the water storage tank 2 and the hot water tank 8 can heat and sterilize the raw water A. Therefore, unlike the conventional case, the raw water in the water storage tank does not directly flow into the hot water tank, which is extremely hygienic.

Moreover, since the raw water in the water storage tank can be boiled little by little by the boiling heater 5 and the hot water can be stored in the hot water tank 8, the temperature of the hot water is sufficiently high. As described above, it is possible to prevent the hot water in the hot water tank 8 from cooling down without mixing the raw water in the hot water tank with the hot water in the hot water tank. Manual switching of can be omitted.
