Abstract

An electromagnetic water heater is composed of a steel pipe, a shower head, an insulating layer, a coil, a sensor and a circuit board, wherein the insulating layer is arranged outside the steel pipe, the coil is arranged outside the insulating layer, and the sensor is arranged at the hot water end in the steel pipe. High-frequency current produced by the circuit board flows through the coil to heat the steel pipe, then the steel pipe transmits heat to water flowing through the steel pipe, and the water is heated. By the adoption of the technical scheme, the electromagnetic water heater overcomes the defects that an existing electric heating wire water heater is low in efficiency, an electric heating wire is easily damaged, and an electric leakage accident occurs easily. The electromagnetic water heater is particularly suitable for places, where water is used for bath, of households and hotels.

Description

A kind of electromagnet water heater

Affiliated technical field

The utility model relates to a kind of water heater, particularly a kind of water heater that utilizes the electromagnetic oven heating principle to realize.

Background technology

At present, water heater can be divided into the classifications such as air-source water heater, heating wire water heater, air-source water heater efficient is high, but cost is also high, buy comparatively difficulty for average family, although the direct-fired electric heater cost of heating wire is low, efficient is low, heating wire damages easily, the electric leakage accident also occurs easily.

The utility model content

Low in order to overcome existing heating wire water-heater efficiency, heating wire damages easily, the shortcoming that the electric leakage accident also occurs easily, the utility model provides a kind of electromagnet water heater to address this problem, and its good effect is to have used electromagnet water heater, utilize electromagnetic induction principle to convert electrical energy into heat energy, greatly improved the efficiency of heating surface, simultaneously safer, longer service life.

The technical scheme that its technical problem that solves the utility model adopts is:

A kind of electromagnet water heater of the present utility model, formed by steel pipe, shower head, insulating barrier, coil, sensor, circuit board, insulating barrier is installed outside steel pipe, coil is installed in outside the insulating barrier, the hot water end of installation of sensors in steel pipe, produce high frequency electric by circuit board and flow through the coil heats steel pipe, steel pipe passes to heat the water that flows through again, and water is heated.

Description of drawings

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

Fig. 1 is the utility model principle schematic.

1. steel pipes among the figure, 2. shower head, 3. insulating barrier, 4. coil, 5. sensor, 6. circuit board.

The specific embodiment

In the embodiment in figure 1, we further specify the utility model as example to implement a kind of electromagnet water heater:

In Fig. 1, steel pipe is common steel tube or iron pipe, so long as ferrimagnet is just, its diameter is according to determining that with discharge its tube wall will have certain thickness, with can fine induced field heating for well; Shower head 2 is common shower head, is installed on the steel pipe; Insulating barrier 3 is enclosed within outside the steel pipe 1, can adopt heat-resisting pottery or other materials to make, and coil 4 is solenoid, its power, the number of turns, coil diameter can be made with reference to common electromagnetic oven, just slightly different, temperature sensor 5 is installed in the steel pipe, is used for measuring the temperature of steel pipe water; Circuit board 6 comprises AC power, the LC oscillating circuit, power control, bridge rectifier, temperature is adjusted, power driving circuit, wave generator circuit, overvoltage detection circuit, the parts such as master control IC circuit, basic identical with electromagnetic oven, because coil of the present utility model and steel pipe relative position are fixed, so comparing with electromagnetic oven not to need the pan testing circuit, when electromagnet water heater is worked, by rectification circuit the alternating voltage of 50Hz is become DC voltage, convert DC voltage to high frequency voltage that frequency is 20-40KHz through control circuit again, will produce alternating magnetic field repeatedly cutting variation in steel pipe 1 on the coil 4, make steel pipe 1 produce cyclic currents (eddy current), and utilize the short circuit fuel factor generation heat of the large electric current of small resistor that steel pipe 1 is generated heat rapidly, and then the water in the heating steel pipe, the temperature of water cooperates the temperature regulation circuit in the circuit board to regulate by temperature sensor 5, give birth to the mode of heating of heat owing to adopted this vibration of electromagnetic oven, reduce the intermediate link that heat transmits, greatly improve heating efficiency.

Adopt scheme of the present utility model, can make in the situation that the cost of electric heater increases slightly, just realized the water heater of a kind of longevity, high efficiency, safety.
