Embodiment Construction

[0011] As shown in the figure: According to the demand of power, the electromagnetic induction heating water device is connected in series and connected. The magnetic core 2 is the ferrite core 2 of half of the magnetic circuit. In the example, the EE magnetic core is selected, and the magnetic circuit has a The direction is an open form, and a coil 10 wound with a thin copper strip is arranged at the open surface of the magnetic circuit. The coil 10 should not exceed the height of the open surface of the magnetic core. The thin copper sheet is used as the isolation shielding layer 6 to eliminate the parasitic capacitance between the coil 10 and the heating water box 5, and reduce the leakage current. The opening 4 is arranged on the isolation shielding layer 6, and the isolation shielding layer 6 cannot form a loop to prevent its short circuit Magnetic field; insulating sheet 3 and heating water box 5 are arranged below the isolation shielding layer 6, and heating water box 5 ...

Abstract

The invention discloses an ultra-small electromagnetic induction water heating device and relates to a fast heater. The electromagnetic induction water heating device adopts series and parallel arrangement according to the power, a magnetic coil is a magnetic coil with a one-half magnetic path, the magnetic path is in an open form in one direction, a coil is arranged on the open surface of the magnetic path, a power supply leading-out wire is arranged on the coil, an isolating and shielding layer is arranged on the side surface of the coil, and an opening is arranged on the isolating and shielding layer; and an insulation sheet and water heating boxes are arranged below the isolating and shielding layer, a water inlet is formed in the upper end surface of the first group of the water heating boxes, a water outlet is formed in the lower end surface of the last group of the water heating boxes, and an anti-dry burning thermal cut-out protector is arranged on the side surface of the last group of the water heating boxes. The ultra-small electromagnetic induction water heating device disclosed by the invention has the advantages of enabling the electromagnetic induction heating device to realize small volume, miniaturization, safety, high efficiency and energy conservation, protecting the device and being more sensitive and accurate; and as the magnetic path is closed, the leakage of an electromagnetic field can be very small, and the different power demands can be met by series connection and parallel connection.

Description

technical field [0001] The present invention relates to a fast heater. Background technique [0002] Existing water heating device utilizes electromagnetic induction to heat a magnetic conductor, and the water is heated through direct heat exchange with the heating element. The water is isolated from the electromagnetic coil with electricity by a relatively thick insulator. The thickness of the insulator is related to the heating The efficiency correlation is small. Although the safety and efficiency are relatively easy to improve, there are still many problems. For example, due to structural problems, the electromagnetic heating coil will be burned due to poor heat dissipation during work, and there is parasitic air between the electromagnetic heating coil and the water. Capacitance exists, and the high-frequency alternating current added to the electromagnetic heating coil will electrify the water through this parasitic capacitance, which will affect the efficiency and saf...
