The carrier in the water pipe first passes through the outer heating channel and then enters the inner heating channel. The inner heating channel is connected to the water outlet.

The electromagnetic heating body includes a high crystal silicon tube 9, a heating rod 12 is arranged inside the high crystal silicon tube, the inner heating channel is formed inside the heating rod, and an external heating channel is formed between the heating rod and the high crystal silicon tube. An electromagnetic induction coil 8 wound around the tube body is arranged outside the high crystal silicon tube.

The upper part of the high crystal silicon tube is provided with an upper support 7 and copper screws 11 for fixing, and the lower part of the high crystal silicon tube is provided with a lower support 10 . The radiator 18 includes an outer casing, and a plurality of slots for water supply pipes are formed in the casing. The water pipe 4 is U-shaped, and two branches are inserted into the slots of the outer casing.

The inlet of the water pipe 4 is connected with a water flow switch 5 and a flow sensor. The electromagnetic induction coil is a multi-strand copper core wire.

The working principle of the present invention is as follows:

First, the magnetic field principle of the circuit system:

1. The power supply of the unit is: 220V/50HZ AC. After the inverter is powered on, the two sets of IGBTs in the inverter will increase the frequency of the output power supply, so that the output frequency of the power supply will rise to 15-20KHZ. The output end of the inverter is connected to the electromagnetic heating The electromagnetic induction coil on the body, when the continuous sinusoidal high-frequency current passes through the electromagnetic induction coil, the inductive heating body generates a high-speed changing magnetic field, thereby converting electrical energy into magnetic energy;

2. Heating principle

1. Heating rod heating principle:

Driven by the frequency converter, the electromagnetic coil generates a high-speed variable magnetic field. Since the heating rod is placed in the magnetic field, the heating rod is magnetized by the magnetic field generated by the electromagnetic induction coil. According to the principle of electromagnetic induction: the conductor placed in the changing magnetic field will generate The electromotive force, the heating rod is a metal material with good electrical conductivity, so the heating rod has a current flow, and the heating rod continues to generate heat under the current flow, generating a large amount of heat energy. When the carrier flows through the inner and outer surfaces of the heating rod, the heat continues. Carried away by the carrier, the carrier is heated.

2. Carrier heating channel

When the carrier passes through the electromagnetic heating body, there are two heating channels, the inner and the outer. The outer channel is a circular channel formed by assembling the inner wall of the high-crystalline silicon tube and the outer wall of the heating rod. The inner channel is the inner wall channel of the heating rod. The carrier first flows through the outer heating channel. channel, and then into the inner heating channel.

3. The carrier is heated for the first time

When the water enters the heating furnace from the water flow switch, it first flows into the frequency converter. When the frequency converter is working, it will generate a lot of heat, which will be conducted to the radiator. The water pipe and the radiator are assembled as a whole. When the frequency converter is working , the heat passes through the radiator and is taken away by the carrier flowing in the water pipe, the frequency converter is cooled down, and the carrier absorbs the heat and the temperature rises, which is called the carrier is heated for the first time.

4. The carrier is heated for the second time

After the carrier flows through the radiator through the outer water pipe for the first heating, it enters the electromagnetic heating body. The carrier first flows through the outer heating channel. When the carrier flows into the outer heating channel, the electromagnetic induction coil will also generate heat when it is energized. Tube conduction, the heat of the electromagnetic coil is absorbed by the carrier, and the temperature drops. In addition, when the carrier flows through the external heating channel, it absorbs a large amount of heat generated by the heating rod itself, and the temperature of the carrier rises. This is called the second heating of the carrier. .

5. The carrier is heated for the third time

When the carrier enters the inner heating channel through the outer heating channel, all the heat absorbed by the carrier comes from the heat generated by the heating rod itself, and the temperature of the carrier rises further, which is called the third heating of the carrier. To sum up, the carrier has been heated three times, absorbing the heat generated by the electrical components of the heating furnace, the heat generated by the electromagnetic induction heating element and the heat generated by the electromagnetic induction coil, so the heat loss is very small and the heating efficiency is very high. high.

Beneficial technical effect of the present invention:

1. When the heating water heater of the present invention is working, there are no moving parts of the machine, and there is no noise pollution and complicated after-sales maintenance;

2. The energy saving is more obvious, because the heat energy generated by the frequency converter and the electromagnetic coil is also absorbed by the carrier, so its heating performance reaches more than 98%, which is much higher than that of ordinary resistance heaters;

3. It can be widely used in household water heaters, without special anti-electricity walls. During the heating process, water and electricity are completely isolated, and there is no risk of electric shock at all, which solves the hidden danger of electric water heaters;

4. The heating effect is direct heating, cold water enters, and hot water comes out directly. The heating power of the heating furnace is large, and there is no need to configure a special water storage tank. The tap water can be directly heated to the bathing temperature, which is convenient and quick;

5. It can be used for room heating. The heating device has stable heating performance and high reliability. As long as an external circulating water circuit is installed, room heating can be realized;

6. Small structure, wall-mounted installation, does not occupy the house area, effectively solves the problem that the current house area is small and there is no effective area to install the electric water heater;

7. Magnetize the water quality and inhibit the survival of bacteria. Because the water is cut by the electromagnetic field, the water quality is softened into small molecular water, which is easy to be used by the human body. At the same time, bacteria cannot be adsorbed on the surface in the high-speed changing magnetic field, effectively inhibiting the generation of bacteria .
