Abstract

The utility model relates to an electric heating device for heating water, in particular to a safe, energy-saving and immediate use electric water heater which comprises an electric heating pipe and a transformer core, wherein, the electric heating pipe is composed of a hollow iron pipe and a copper pipe which are connected in series and is wound on the transformer core, part of the copper pipe and the iron pipe are wound at the same side of the core, and the other part is wound at the other side; the special transformer type electric water heater is characterized in that the iron pipe is wound at one side of the core, the copper pipe is connected with the iron pipe, and the port of the copper pipe is connected in short circuit; the primary coil thereof adopts a common copper coil, the copper pipe is connected on the tap-water pipe, induction current is generated in the copper pipe and the iron pipe after the primary coil is electrified, the cold water flows into the iron pipe from the copper pipe, the pipes emit heat, the water is heated instantaneously, and the hot water flows out from the iron pipe; because the secondary coil is connected in short circuit, the ground pressure is zero volt; the electric water heater is safe in use and simple in structure, can be used at any time, does not need heat preservation and heating, can better save energy, and occupies little space.

Description

A kind of electric heater that uses with the opening

Technical field:

The utility model relates to the electric heater unit that is used to add hot water, refers in particular to a kind of electric water heater that uses with the opening of energy-saving safe.

Background technology:

At present, existing electric heater generally all is to be made of electrical heating wire, inner bag, temperature controller etc. on the market.In use, the temperature that keeps water will switch on heating once for all needing every certain interval of time usually, so not only wasted more electric energy, brought bigger hidden danger also for simultaneously the security of using, and often the volume of these devices is all bigger, can waste bigger space.

The utility model content:

The purpose of this utility model is the problem at above-described existing electric heater waste electric energy, provide a kind of simple in structure, energy-saving safe, volume little, need not the electric water heater that is incubated heating, can uses with the opening.

A kind of electric heater that uses with the opening, it comprises electric heating tube and transformer core, electric heating tube is in series by hollow iron pipe and hollow copper tubing and is wrapped on the transformer core;

Described transformer core is a circular iron core;

A copper pipe part and iron pipe are entangled in the homonymy of iron core, and a part is entangled in opposite side; Iron pipe is entangled in iron core one side and is connected iron pipe with copper pipe short circuit on circuit is connected with copper pipe end.

The beneficial effects of the utility model are: comprise electric heating tube and transformer core owing to adopted, and electric heating tube is in series by hollow iron pipe and copper pipe and is wrapped on the transformer core, a copper pipe part and iron pipe are entangled in the homonymy of iron core, and a part is entangled in opposite side; Iron pipe is entangled in iron core one side and is connected iron pipe and the copper pipe end so a kind of special transformer type electric heater that short circuit is connected on circuit with copper pipe, its primary coil adopts general copper coil, and secondary coil then is made up of the electric heating tube that hollow iron pipe and copper pipe are in series.Actual is to make secondary coil with iron pipe that is cascaded and copper pipe to be wrapped on the transformer core, and the short circuit of coil two connects, and copper pipe is connected on the running water pipe.Produce induced-current in primary coil energising back copper pipe and the iron pipe, cold water enters iron pipe by copper pipe, the pipe heating, instant water is heated, hot water is flowed out by iron pipe, because being short circuit, secondary coil connects, and be zero volt so press on ground, can be very safe in the use, use at any time, and do not need the insulation heating, can save the energy preferably, simple in structure, it is little to take up space.

Description of drawings:

Fig. 1 is circuit theory diagrams of the present utility model;

Fig. 2 is a structural representation of the present utility model.

Specific embodiment:

Below in conjunction with accompanying drawing the utility model is further described;

See accompanying drawing 1 and accompanying drawing 2, it comprises electric heating tube and transformer core 3, and electric heating tube is in series by hollow iron pipe 1 and hollow copper tubing 2 and is wrapped on the transformer core 3; Described transformer core 3 is circular shape iron core; Copper pipe 2 parts and iron pipe 1 are entangled in the homonymy of iron core 3, and a part is entangled in iron core 3 opposite sides; Iron pipe 1 is entangled in that iron core 3 one sides are connected iron pipe 1 with copper pipe 2 and the short circuit on circuit of copper pipe 2 ports is connected to form the transformer type electric heater, and its primary coil is general copper coil 4, and secondary coil then is made up of the electric heating tube that iron pipe 1 and copper pipe 2 are in series.Copper coil 4 energising back iron pipe 1 heatings, heating cold water.All be tied with insulating tape on iron pipe 1 and the copper pipe 2, hot water outlet is connected at the closed place of iron pipe 1 and copper pipe 2 short circuits with cold water inlet.The copper coil 4 that is entangled in iron core 3 is connected with switch 5 simultaneously, has ground wire 6 to be welded on the iron core 3.Copper pipe 2 is connected on the running water pipe, produces induced-current in primary coil energising back copper pipe 2 and the iron pipe 1, and cold water enters iron pipe 1 by copper pipe 2, the pipe heating, instant water is heated, and hot water is flowed out by iron pipe 1, because being short circuit, secondary coil connects, so press on ground is zero volt, can be very safe in the use, use at any time, and do not need insulation to heat, can save the energy preferably, simple in structure, it is little to take up space.

The above embodiment only is preferred embodiment of the present utility model, does not therefore limit protection domain of the present utility model, so the equivalence that all shapes according to the utility model, structure and principle are done changes, all should be covered by in the protection domain of the present utility model.
