Electromagnetic energy water heater

Abstract

The invention discloses an electromagnetic energy water heater. The electromagnetic energy water heater comprises a water pipe, a metal heating piece arranged in the water pipe, a magnet exciting coilwound around the outer surface of the water pipe, an alternating current signal generating unit electrically connected with the magnet exciting coil, and an ultrasonic transducer arranged on the water pipe, and the alternating current signal generating unit is electrically connected with the ultrasonic transducer. The alternating current signal generating unit generates alternating current signals to be transmitted to the magnet exciting coil, under the effect of the alternating current signals, the magnet exciting coil generates a changing magnetic field, the metal heating piece generates aneddy current in the changing magnetic field due to electromagnetic induction, and thus the metal heating piece generates heat to heat a water flow in the water pipe. In addition, the alternating current signal generating unit can also transmit the alternating current signals to the ultrasonic transducer, the ultrasonic transducer generates an ultrasonic wave under driving of the alternating current signals, the ultrasonic wave is conducted on the water pipe, and thus scale on the water pipe can be removed so as to prevent accumulation of the scale.

Description

technical field [0001] The invention relates to the field of heating equipment, in particular to a water heater. Background technique [0002] As a device that can provide hot water conveniently, water heaters have become an essential item in family life. The common heating methods of water heaters are: gas heating, solar heating and electric heating rod heating. However, the gas heating method will produce toxic gas when used, and an additional exhaust channel needs to be installed, which is troublesome to install and has a low safety factor; the solar heating method is greatly affected by the weather and requires a long heating time, which is troublesome to use; electric heating Although the rod heating method is simple to install and convenient to use, there is a risk of electric leakage because the charged heating rod is in direct contact with the water. [0003] In this regard, electromagnetic energy water heaters that use electromagnetic induction for heating have app...
