Electromagnetic water heater with modularized structure

Abstract

The invention discloses an electromagnetic water heater which uses electromagnetic heating theory to realize water-electricity separation and high safety. Wherein, the heating unit comprises: the outset part is a thermal-insulated ceramic cup sleeve coiled with electromagnetic coil; the inner part is a embedded multilayer metallic electromagnetic heating tube; the end is sealed by the a cover with cold water inlet and hot water outlet; the embedded structure and effectively increase the path of water; the water flows two surfaces of metallic electromagnetic heating tube, to increase the heated area and improve the heat exchange efficiency; the water will flow from outer to inner, therefore, the water will be stepped heated to decrease the heat loss most; the cold water first flows between the ceramic sleeve and the outset metallic electromagnetic heating tube, to cool the electromagnetic coil. The invention has simple structure, modularized processing and installment, while several heating units can be serially connected to realize multi-step heating.

Description

technical field [0001] The invention relates to an electromagnetic water heater, namely, the field of heating water or other liquids through the principle of electromagnetic heating. Background technique [0002] Electromagnetic water heater is an appliance that uses the principle of electromagnetic induction to heat water (liquid). Its working principle is: the electromagnetic induction coil in the electromagnetic water heater generates an alternating magnetic field after being connected to an alternating The electromagnetic heating element in the variable magnetic field generates eddy current to generate heat under the action of the alternating magnetic field, thereby heating the water (liquid) flowing through the surface of the electromagnetic heating element. The electromagnetic water heater has the advantages of high thermal efficiency, separation of water (liquid) and electricity, and good safety. Therefore, some enterprises or individual inventors have proposed innov...

AI Technical Summary

Problems solved by technology

The electromagnetic water heaters designed in the above three inventions have their own characteristics, but they all have problems such as complex structure, high manufacturing cost, and difficult maintenance; (Liquid) conducts heat exchange or does not directly exchange heat with water, so there are problems of heat loss and how to collect the lost heat energy, and how to cool down the electromagnetic induction coil or increase the heat resistance of the coil.
