Heating magnetizing device of instant heating type civil electromagnetic water heater

Abstract

The invention discloses a heating magnetizing device of an instant heating type civil electromagnetic water heater. The invention solves the problems that in the prior art, the structure of the core cylinder is complex and the diameter is small, the core cylinder is only suitable for water supply of a water storage tank which has a low hot water yield and depends on accumulation, and is not suitable to be used in equipment such as an instant heating type bathroom water heater with larger water consumption, the tortuous water passage is easy to block, and the active function of the magnetized water is not obvious. The main point of the technical scheme is that: the heating magnetizing device of the instant heating type civil electromagnetic water heater comprises a plastic shell, a port sealing cover, a magneto-conductive metal core cylinder and an electromagnetic coil, wherein the port sealing cover is connected to a port of the plastic shell; the plastic shell or the port sealing cover is provided with a water inlet interface and a water outlet interface; the core cylinder is positioned in the inner cavity of the plastic shell; and the electromagnetic coil is wound on the outer side of the plastic shell. The heating magnetizing device is characterized in that the core cylinder is a totally closed hollow body with a smooth surface; a limiting rib is arranged between the inner cavity wall of the plastic shell and the outer wall of the core cylinder, so that the core cylinder is limited in the centre of the inner cavity of the plastic shell; the distance from the surface of the plastic shell wound with the electromagnetic coil to the outer wall surface of the core cylinder ranges from 0.5-15mm.

Description

technical field [0001] The invention relates to working parts of civil hot water supply equipment, in particular to a heating and magnetizing device of an instant heating type civil electromagnetic water heater. It is suitable for instantaneous electromagnetic hot water equipment with large water consumption, such as bathroom water heaters. Background technique [0002] The electromagnetic civil water heater is an electric water heater with good safety and high thermal efficiency. Like the electromagnetic water heater of Chinese Patent No. 03223399.X, its structure includes a heating part, an induction coil for heating, a control circuit part, a cold water pipe, a hot water pipe and a housing. The control circuit part consists of a power supply, a frequency conversion circuit, a control circuit and a protection It is composed of a circuit. The heating part is at least one outer surface covered with a metal magnetic material cylinder covered with an electric and thermal insu...

AI Technical Summary

Problems solved by technology

[0005] In order to overcome the complex structure of the metal core rod existing in the existing similar electromagnetic water heaters, the diameter cannot be large, it is only suitable for the water supply of the water storage tank with a small hot water production rate, and it is not suitable for the instant heating type with a large water consumption. The use of bathroom water heaters and other equipment, the water channel is too tortuous, easy to block and difficult to dredge, the degree of water magnetization is low, and the beneficial effect of magnetized water is not obvious. The purpose of the present invention is to provide an improved instantaneous civil electromagnetic water heater. The heating and magnetizing device can overcome the defects of the prior art
