Abstract

The utility model relates to a power frequency electromagnetic induction water heater which causes the tap water with the normal temperature to be heated to the bating temperature. A hollow annular iron core is inserted into the pipe passage of the tap water, and the hollow annular iron core are wound with N turns of conducting wires. When the iron core is energized with the 50HZ alternating current, the alternating electromagnetic field can be induced out the large vortex in the iron core to heat the iron core and water. In the circuit, a temperature controller is used to control the on-off of the electric current to ensure the temperature for bathing. Because of the isolation of the water and the electricity, the utility model has the advantages of safety, rapidness, continuous hot water feed, and easy operation and use.

Description

Main-frequency electromagnetic induction formula electric heater

The utility model relates to a kind of main-frequency electromagnetic induction formula electric heater that room temperature water in the running water pipe directly is heated to the bathing temperature.

The water heater of widespread usage mainly contains combustion type and electrothermal at present, and gas water heater can be supplied with hot water fast continuously, but its improper use meeting produces carbon monoxide, jeopardizes people's life; Electric heater is to utilize the water tank water storage mostly, and heating places water, and it can not continuous water supply, can only be interrupted use, and water is charged during as the device electric leakage, and accident very easily meets accident during bathing.

The purpose of this utility model is that a kind of hot water of supplying with rapidly, continuously will be provided, safe line-frequency induction formula electric heater easy to use, the disadvantage that it can avoid above-mentioned water heater to exist effectively.

The purpose of this utility model is achieved in that and casts out a hollow pipe on the closed hoop iron core, its two ends link to each other with running water pipe, and insulating barrier is arranged on iron core, and are evenly close around lead N circle on it, by 50 He Zhi industrial-frequency alternating currents, alternating current produces alternating magnetic field on iron core, the iron core cutting magnetic line produces induced electromotive force, makes and produces a huge eddy current in the iron core, this eddy current is closed form, can only make the iron core heating, heat be taken away, become hot water by the running water of iron core.At the iron core delivery port temperature controller is housed, the break-make of control electric current makes water temperature remain on the bathing temperature.

The utility model has the advantages that: 1. because iron core and lead tightly insulate, only rely on magnetic line of force commissure to make the iron core heating, water flows through in iron core, and water power is isolated, and guarantees safety; 2. this device is easy for installation, only need be serially connected in the tap water pipe line, connects power supply when needing hot water, flows out cold water after the outage as usual; 3. operation is very easy in use, and household electrical appliance such as electric light, electric cooker are safe and simple as using, rapidly, continuously hot-water supply, more points for attention.

Below in conjunction with drawings and Examples the utility model is specified.

Fig. 1 is the utility model structure cutaway view.

Among the figure: 1 iron core, 2 hollow pipes, 3 insulating barriers, 4 leads, 5 water inlet pipes, 6 outlet pipes, 7 temperature controllers, 8 casings, 9 indicator lamps, 10 attaching plugs.

As shown in Figure 1, a kind of main-frequency electromagnetic induction formula electric heater, it mainly is to have a closed hoop iron core (1), iron core (1) direct casting has hollow pipe (2), the two ends of pipeline (2) are connected with outlet pipe (6) with water inlet pipe (5), and the internal diameter and the running water pipe internal diameter of hollow pipe (2) are complementary, and iron core (1) surface is topped insulating barrier (3), insulating barrier (3) is gone up evenly close around lead (4), and decide according to power in the number of turn and line footpath.Closed hoop iron core (1) is ring shape, circular arc or ellipse.At outlet pipe (6) end temperature controller (7) is housed, iron core (1) is contained in the casing (8), draws lead (4) attachment plug (10) in the casing (8).Indicator lamp (9) is arranged on the case (8), and it is promptly bright to switch on.When needs hot water, as long as plug (10) is inserted on the supply hub, after second, the tap of fetching boiling water just has hot water to flow out continuously through 3-5.
