Abstract

The utility model discloses an electromagnetic induction instant water heater. A primary side coil (5) and a secondary side coil (8) are arranged on a winding core type transformer ferrite core (1) and the secondary side coil (8) is made by adopting a wound insulated copper pipe. Short connection points (9) are installed at the head end and the tail end of the copper pipe and both ends of the copper pipe are respectively a water inlet end (10) and a water outlet end (11). When a water inlet valve is opened, a water current switch is closed and the primary side coil of the transformer is electrified, then strong induction electrical current flows through the secondary side coil and the temperature of the water in the copper pipe used as the secondary side coil is raised quickly, and then the hot water flows out from the water outlet end without breaking. The utility model has effective isolation between the water and the electricity, and has safety in use, simple structure and easy manufacture and maintenance. One transformation process of the electromagnetic induction makes the secondary side coil generate strong electrical current to be heated to heat the water in the copper pipe, enhancing the efficiency and reducing the energy consumption.

Description

The electromagnetic induction type immediately heating water heater

Affiliated technical field

The utility model is a kind of electromagnetic induction type immediately heating water heater that utilizes electromagnetic induction principle to make, and also can be used in the heating system of other liquid.

Background technology

The electromagnet water heater of Xiao Shouing is that alternating current is become direct current produces a upper frequency again through the vibration inversion alternating current after rectification in the market, makes it to produce eddy current ferromagnetic material is heated, and reaches the purpose to the water heating then.The electromagnet water heater intermediate conversion links is many, and energy loss is big, so electromagnet water heater power is bigger, and 120 liters of electromagnet water heater power of importing and exporting the temperature difference 25 degree Celsius of one hour water yield are more than 4.5KW.

Summary of the invention

In order to overcome the deficiency of electromagnet water heater, the utility model provides a kind of electromagnetic induction type immediately heating water heater, and this water heater is simple in structure, is easy to make, and water power separates, and safe in utilization, energy consumption is low, the efficient height.

The technical scheme that the utility model technical solution problem is adopted is: on the core type transformer iron core once lateral coil and second siding ring with electromagnetic wire coiling first siding ring, second siding ring adopts the copper tube coiling that has insulation, establish the short circuit point on the two ends of copper tube, the copper tube head end is a water inlet end, and the tail end of copper tube is the water side.

When the first siding ring of transformer feeds alternating current, second siding ring produces powerful induced-current, according to the fuel factor principle of electric current, will produce a large amount of heat energy as the copper tube of transformer secondary lateral coil the water in the pipe is rapidly heated, the water side is just flowed out hot water endlessly.In this process, there is not the contact of electricity between the power and water, have only the contact of magnetic, therefore safer.

The beneficial effects of the utility model are: 1. effectively isolate between water and the electricity, and safe in utilization; 2. simple in structure, be easy to make and maintenance; The transfer process that 3. one electromagnetic induction only arranged, second siding ring produce big electric current and the interior water of heating copper tube that generates heat, and have reduced energy consumption; 4. adopt core formula structure transformer iron core, improved the turn ratio of first and second lateral coil, promptly the length of copper tube has increased, according to Lenz's law as can be known the delivery port leaving water temperature will increase, improved efficient.

Description of drawings

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

Fig. 2 is a structure chart of the present utility model

Among the figure: 1 core type transformer iron core, 2 water flow switches, 3 water flow switch contacts (1), 4 water flow switch contacts (2), 5 first siding rings, 6 first siding ring head ends, 7 first siding ring tail ends, 8 second siding rings, 9 second siding ring two ends short circuit points, 10 second siding ring water inlet ends, 11 second siding ring water sides

The specific embodiment

As shown in Figure 1, 2, once lateral coil 5 and second siding ring 8 on a core type transformer iron core 1, first siding ring adopts F level or the coiling of H level electromagnetic wire, first siding ring head end 6 places establish water flow switch contact 3, first siding ring tail end 7 places establish water flow switch contact 4, second siding ring 8 adopts the copper tube coiling that has insulation, second siding ring is that the two ends of copper tube are respectively water inlet end 10 and water side 11, establish second siding ring two ends short circuit point 9 on the two ends of copper tube, water flow switch 2 is connected on the head end of second siding ring 8.

When inlet valve is opened, water flow switch 2 closures, 5 energisings of transformer first siding ring, second siding ring 8 just has powerful induced-current to flow through, and is rapidly heated as the water in the copper tube of second siding ring, so water side 11 is just flowed out hot water endlessly.

For the volume and weight that reduces complete machine as far as possible and be convenient to make and maintenance, it is the transformer of two iron core column that the utility model adopts the transformer of core formula structure, first and second lateral coil is evenly distributed on two iron core column, and effectively insulation isolation between first and second lateral coil, with plan safety.

Calculate and experimental results show that 120 liters of one hour water yields through theory, the electromagnetic induction type immediately heating water heater volume of out temperature difference 25 degree Celsius is less than 0.012 cubic metre, and power demand is 3.8KW.The utility model can reduce power according to the needs increase of water yield size, temperature difference height.
