Abstract

The utility model relates to an induction heating instant electrical water heater which is characterized in that the utility model adopts a closed iron core, and a primary winding which uses an industrial frequency power source as a working power source is arranged on the iron core to close a conducting ring used as a secondary winding. A heat exchange water channel is arranged in the closed conducting ring. Due to the adoption of an induction heating mode, the utility model can be used when opened and the utility model has the advantages of high safety and reliability and high heat efficiency. The utility model can be made into a water heater as well as a boiling water heater.

Description

Direct induction heating type electric water heater

The utility model relates to water heater.More particularly, be a kind of instant electric water heater.

Electric heater of the prior art is of a great variety, and structure is different.Wherein, the heating of water-storage electric heater is to put into spiral metallic resistance silk in a metal tube vertically.Enter practical electric heater and mostly be this structure; The heating element heater that the instant electric water heater adopted is a platy structure, this electric hot plate be equally with resistance wire as heater, make insulant with magnesia, flow through the slit of water between two heating plates and be heated.Obviously, no matter be storage water heater or instant electric water heater, all be to adopt direct electrically heated working method.Therefore, electric heater of the prior art exists safety problem inevitably.Though existing electric heater product is provided with earth leakage protective device in its electric power loop, this can not fundamentally be avoided because the security incident that electric leakage causes.

The purpose of this utility model is to avoid above-mentioned weak point of the prior art, and a kind of direct induction heating type electric water heater is provided, with the electric leakage problem of thorough solution electric heater.

The purpose of this utility model is achieved through the following technical solutions:

System point of the present utility model is that employing is iron core-closed, on iron core, is provided with the elementary winding of power frequency supply as working power, and be secondary windings with closed conducting ring, the heat exchange water route is arranged in this closure conducting ring.

Compared with the prior art, the utility model has the advantages that:

1, the utility model adopts induction mode of heating, and heating element heater and working power are isolated, thereby has thoroughly eliminated the hidden danger of electric leakage, and is safe and reliable.

2, the utility model need not to be provided with the water storage casing, and volume is little, in light weight, easy for installation, plug and play.

3, the utility model heater element profile such as same transformer replace secondary windings by closed conducting ring.In the work, the heat that has only iron loss and elementary copper loss to produce becomes loss, and the heat that produces in the secondary conducting ring is all utilized.Thereby, the utlity model has the very high thermal efficiency.

4, the utility model heats up rapidly, both can be used as water heater, also can be made into boiler.

5, in the utility model the induction type mode of heating to certain magnetization being arranged by the glassware for drinking water of its heating.According to the interrelated data introduction, this water that is magnetized has suitable health care to human body.

6, the utility model has emollescence for incrustation scale, thereby can avoid scaling, when using as boiler, does not need regular scale removal.

Fig. 2 is the modular construction schematic diagram among Fig. 1.

Fig. 3 is the utility model embodiment 2 structural representations.

Fig. 4 is the modular construction schematic diagram among Fig. 3.

By the following examples, in conjunction with the accompanying drawings the utility model is further described.

Embodiment 1:

Referring to Fig. 1, it is iron core-closed 1 that present embodiment adopts, on iron core 1, be provided with the elementary winding 2 of power frequency supply as working power, and be secondary windings with closed conducting ring 3, the heat exchange water route is arranged in this closure conducting ring 3.

Referring to Fig. 2, the closed conducting ring 3 in the present embodiment is a tubular structure, and is provided with water inlet pipe mouth 4 and the effluent pipe mouth 5 that is communicated with cold water pipe and hot-water line respectively, at this water inlet pipe mouth 4 and effluent pipe mouth 5 places, engages with electric conductor 6.

As shown in Figure 1 and Figure 2, the working power in the present embodiment is single-phase.

Embodiment 2:

Referring to Fig. 3, Fig. 4, different is that the working power in the present embodiment is a three-phase with above-mentioned enforcement embodiment 1.Corresponding iron core-closed (1) that is provided with is " SD " type, and three phase windings of coiling on it can be " Y " shape connection, also can be " △ " shape connections.The closed conducting ring that is arranged on secondary also has three groups, and each organizes independent Cheng Huan, and each group is connected on the water route each other simultaneously, has same water inlet pipe mouth (4) and effluent pipe mouth (5).

Claims

1, direct induction heating type electric water heater, it is characterized in that adopting iron core-closed (1), going up setting with the elementary winding (2) of power frequency supply as working power at iron core (1), is secondary windings with closed conducting ring (3), and the heat exchange water route is arranged in this closure conducting ring (3).

2, direct induction heating type electric water heater according to claim 1, it is characterized in that described closed conducting ring (3) is a tubular structure, and be provided with water inlet pipe mouth (4) and the effluent pipe mouth (5) that is communicated with cold water pipe and hot-water line respectively, locate at described water inlet pipe mouth (4) and effluent pipe mouth (5), engage with electric conductor (6).
