Description

A kind of electromagnet water heater

Technical field

The utility model provides a kind of electromagnet water heater of electric field.

Background technology

Before the utility model proposes, existing electric heater normally is installed in electrothermal tube in the container and constitutes.Owing to electrothermal tube is realized the electric heating conversion by the resistance heat effect, and lean on the conduction of conductor heat to feed water, exist deficiency to be: 1, resistance heat conversion, conversion efficiency is low; 2 electrothermal tubes determine that thermal inertia is big, and firing rate is slow; 3, metallic conductor is made protective layer and heat conduction layer, easily electric leakage; 4, long-term water storage in the container is easy to generate sediment, needs often cleaning; 5, the water programming rate in the container is slow, and can not reach promptly heats promptly uses; 6, because the water in the container is warmed under certain temperature conditions and could uses, when stopping using, go back surplus hot water, fearless waste electric energy in the container.

Summary of the invention

The utility model provides a kind of electromagnet water heater of new construction at the shortcoming of existing electric heater.Its content is: be connected with power line and be provided with switch on the housing of electromagnet water heater, power setting device, temperature setting device and blower fan are installed on housing.The high frequency electric supply is installed in housing and is connected with the solenoid of heater by the high frequency electric output lead.By support urceolus is installed in the heater inner core outside and constitutes the heating water jacket, on inner core heating water jacket's inwall, be provided with the antiscale layer.Outer tube wall downside the heating water jacket is connected with water inlet pipe, is connected with outlet pipe at upside.The outside at outer tube wall is set with insulation tube by the air gap spacer ring, forms air gap between insulation tube and outer tube wall.The outside at insulation tube is equipped with solenoid, is provided with protective cover in the coil outside.

Electromagnet water heater provided by the utility model is to utilize the eddy current pyrogenicity principle of electromagnetic induction to come the heating water jacket to make to flow through the water of water jacket to be heated and reach and use the hot water purpose.High frequency alternating current by heater coil forms the induction field loop between protective cover and outer tube wall; eddy current generates an electromagnetic field on outer tube wall simultaneously; consumed power produces heat energy; barrel is heated up; again with the water generates heat exchange of passing through water jacket; water temperature is raise, reach effect the water heating.Thereby, when having electric current to pass through in the coil, on barrel, produce the electromagnetic eddy effect immediately, water is heated up immediately and heated.Therefore can realize fast thermal effect, need not wait for, and thermal inertia be little, save electric energy.Moreover, because coil is installed in the insulation tube in the outside of water body, and, between insulation tube and outer tube wall, also be provided with air gap, can reach thorough insulation, can not produce the charged phenomenon of water body, can not leak electricity yet, guaranteed the safety of water.Simultaneously, set air gap also can play the thermolysis to coil, the service life of favourable extension coil.Also have, the water in the heater does not have the deposition of incrustation scale with using with flowing, and does not have the delay of dirt yet and pollutes the heater inwall, because the water jacket inner tube wall is provided with the antiscale layer, does not have scale build-up yet, has the effect of sanitation and hygiene.
