Electromagnetic heating device for cyclic heating of large commercial water storage station

Abstract

The invention provides an electromagnetic heating device for cyclic heating of a large commercial water storage station. The device is reasonable in design, simple in structure, safe, reliable and capable of effectively preventing dry burning. The device comprises the water storage station and further comprises a cylindrical heating water tank and an electromagnetic induction coil wound around the outer wall of the heating water tank and used for electromagnetic induction heating of the heating water tank, wherein the top end and bottom end of the heating water tank are communicated with the top end and bottom end of an inner cavity of the water storage station through a water inlet pipe and a water outlet pipe respectively, and a circulating water pump is installed on the water inlet pipe or the water outlet pipe. According to the scheme, due to the fact that the water-electricity separation is achieved for the water storage station used for storing water and the heating water tank used for heating, a water heater is safer; besides, due to the fact that the heating water tank is of the cylindrical structure, the heat transfer area is large and forced circulation temperature difference is small during water heating, and then water scale is not prone to forming.

Description

technical field [0001] The invention relates to the technical field of water heater equipment, in particular to an electromagnetic heating device for circulating heating of large-scale commercial water storage. Background technique [0002] In the process of heating and using the traditional commercial water heater, when the hot water heated to a certain temperature flows out from the water outlet, the water inlet pipe connected to the upper part of the water tank cavity starts to supply water. During this process, a large amount of cold water pours in and The original hot water is mixed, so that the heating device will reheat it. This structural mode not only reduces the overall water temperature but also greatly reduces the waste of electric energy. There is a huge potential safety hazard. Once the magnesium oxide powder on the surface of the resistance wire is burned, the high-voltage current will directly flow into the water, which will make the water in the water heater...
