The closed heat storage tank is a cylindrical closed body made of ferromagnetic material. The upper part of the tank has a water inlet and a vent. There is a float valve in the vent. The lower part of the tank has a water outlet. There are 3-5 leaking holes distributed on the heat storage drain plate, which are arranged in a water-retaining manner. The tank body is divided into heat insulation layer, insulation layer, electromagnetic coil, insulation layer, electromagnetic protection layer, and tank body from inside to outside. A temperature-sensing element is attached to the ferromagnetic material; the electromagnetic coil is energized under control to generate an electromagnetic field, which acts on the ferromagnetic material of the tank body to generate a thermal effect, and at the same time, the heat storage drain plate is heated by conduction, and the tank body is in a heat preservation state at the same time, and the heat is accumulated. The temperature sensing element senses the temperature of the tank immediately, and controls the electromagnetic heating tank to the set temperature.

Further, when the thermal storage heating tank of the drinking water machine is used, the water can be quantitatively discharged. When taking water, the quantitative switch is turned on, and the water enters the tank and is heated at the same time. When the water is full, the vent is closed, the water outlet is opened, and the water is discharged; To discharge water, turn on the normally open switch, and the upper water will be heated and discharged continuously through the water outlet.

Beneficial effects: the heat storage heating tank of the drinking water machine obtained by the present invention is heated by an electromagnetic coil, the heat source tank body is controlled by the temperature sensing element, the temperature of the tank body is controlled at less than or equal to 100°C, and the heat is stored, and no heat is generated when passing water A large amount of water vapor, due to the heat storage in the tank, is heated by the water, and there is no residual water in the tank. The invention has the advantages of simple structure, convenient manufacture and no potential safety hazard.
