Air duct type magnetic energy water heater

Abstract

The invention provides an air duct type magnetic energy water heater. Magnetic energy is used for heating. The air duct type magnetic energy water heater is composed of a heating chamber, an electricchamber and a heat dissipation air duct. The heating chamber is isolated from the electric chamber and the heat dissipation air duct in a sealed manner. Only a heating water tank, an electromagnetic valve isolated from the mains supply, a water flow sensor and a temperature sensor are arranged in the heating chamber, the water leakage and electric leakage do not exist, and the magnetic energy water heater is a real water and electricity separation magnetic energy water heater which is long in service life and free of maintenance.

Description

technical field [0001] The invention relates to a household electrical appliance, namely an air duct type magnetic energy water heater. Background technique [0002] So far, the instant electromagnetic water heaters on the market, including the electromagnetic water heaters with the patent number ZL200620095370.9 and the application number 200920224006.1, not only have large electromagnetic radiation like the induction cooker, which is not environmentally friendly, but also have the same effect as the patented ones in the heating process. The water tank with the number ZL200620095370.9, firstly, air and water vapor will accumulate at the center and upper position in the direction of water inlet and outlet, so that the upper part of the heat generating body cannot contact with water, resulting in local dry burning, which will make the water tank The upper part is damaged due to excessive temperature rise, which will cause thermal deformation of the shell in severe cases, and ...

Problems solved by technology

In addition, the heat dissipation bracket is generally aging or damp and is also prone to leakage, so it seems that the separation of water and electricity is actually more dangerous than the traditional water storage electric water heater;

[0005] (2) Since the coil between the two water pans relies on insulating and heat-insulating ceramic sheets for both insulation and heat conduction medium on the coil, the thicker is better in safety, but the thermal conductivity is poor, and the thinner is better in heat dissipation, but the insulation is poor. , the contradictory relationship between the two is very difficult to deal with, especially once the water tank has repeatedly expanded with heat and contracted with cold for a long time, and now the water pressure of the water pan on the high floor is high, once the water tank leaks, electric leakage accidents cannot be avoided

In addition, the wire reel sandwiched in the insulating and heat-insulating ceramic sheet takes a long time to heat up, and the enameled wire insulation layer of the length of the wire reel is prone to aging, which reduces the thermal efficiency.

[0006] (3) Since cold water flows from top to bottom, contrary to hot water convection, the water temperature in the upper part of the water tray farther from the water inlet will rise, which not only affects the heat dissipation of high-power tubes, but also makes it difficult for the generated water vapor to flow from the upper part 2-3mm The exhaust connecting pipe of the exhaust pipe is exhausted, so there will be local dry burning and damage to the water pan, and consistent water leakage will lead to serious casualties due to electric leakage

[0007] (4) The water inlet pipe, the water tray, the water outlet pipe and the water and the user form a closed loop. The number of turns of the electromagnetic coil is about 30, with a ratio of about 1:30. The self-inductance voltage of the electromagnetic coil is at It is about 1000v, so under the action of the high-frequency coil, an induced voltage of more than ten volts or even higher will be generated. This voltage is extremely harmful to the bather, so that an induced voltage electric shock accident will occur

[0008] (5) In the direction of the water flow in the water pan, once it is used in an area with poor water quality for a long time, scale and other sediments will block the connecting water pipe and cannot be used. If the water pan is blown under high-pressure water flow, the leakage will be serious. casualty accident

[0009] (6) Since the water pan, coil, and circuit are in one space, leakage of water in the water pan and other waterways or components in the shell will inevitably lead to major leakage accidents, so there are too many safety hazards and it is not safe to use
