Induction cooker

Abstract

The invention relates to an induction cooker, belongs to the technical field of ovens, and solves the technical problems that the electromagnetic radiation exists and the heating efficiency is low in an existing induction cooker. The induction cooker comprises a cooker seat and a turnplate, wherein the turnplate is a flat non-magnetic insulating plate body and is rotatably mounted on the cooker seat; an even number of permanent magnets are fixed on the turnplate; the magnetization direction of each permanent magnet is parallel to the rotation axis of the turnplate; the permanent magnets are arranged in an axial symmetry manner around the rotation axis of the turnplate in a polarity alternating manner; and the cooker seat is provided with a power machine for driving the turnplate to rotate and fixedly provided with a pot bracket for holding heated pots. The induction cooker is free from the electromagnetic radiation, low in energy consumption, high in heating efficiency, and little in limit on the heated pots, and can continuously regulate the temperature. The induction cooker can be used as kitchen cooking equipment in households, mess halls, restaurants and hotels, or can be used for field cooling.

Description

technical field [0001] The invention relates to stove technology, in particular to an induction cooker technology. Background technique [0002] Existing electric heaters mainly include resistance wire electric furnaces, microwave ovens, induction cookers and the like. The traditional resistance wire electric furnace has been basically eliminated due to low efficiency and poor safety. Although the microwave oven is easy to use, its heating efficiency is only 50%-60%, and it is difficult to display cooking technology; the heating efficiency of the induction cooker is as high as 80%. No open flame, more popular with users. [0003] However, the existing induction cooker has the following defects: 1) the existing induction cooker cannot adjust the temperature steplessly; 2) the existing induction cooker must use iron pans or stainless steel pans; 3) the electromagnetic wave frequency of the existing induction cooker is about 25KHz, which is harmful to the human body Harmful r...

The traditional resistance wire electric furnace has been basically eliminated due to low efficiency and poor safety. Although the microwave oven is easy to use, its heating efficiency is only 50%-60%, and it is difficult to display cooking technology; the heating efficiency of the induction cooker is as high as 80%. No open flame, more popular with users

[0003] However, the existing induction cooker has the following defects: 1) the existing induction cooker cannot adjust the temperature steplessly; 2) the existing induction cooker must use iron pans or stainless steel pans; 3) the electromagnetic wave frequency of the existing induction cooker is about 25KHz, which is harmful to the human body Harmful radiation; 4) After the existing induction cooker is taken away from the cooker, the oscillating coil is still working and still outputs electromagnetic waves, which consumes energy and damages the health of the cook; 5) even if it is turned off (no heating electromagnetic waves are generated), the The power cannot be cut off immediately, because the temperature inside the machine is high, and the cooling fan must continue to work to cool down
