An induction cooktop suitable for ceramic, glass or metal pans

technical field

The invention relates to an electromagnetic cooker or an electromagnetic cooker. the

Background technique

Electronic stoves have the advantages of no open flame, no smoke, no harmful gas, etc., and have become the first choice to replace traditional open flame stoves. At present, the electronic stoves circulating on the market are basically divided into two categories, one is electric stoves, and the other is electric stoves. Similar to induction cooker, electric furnace, as the name implies, converts electric energy directly into heat energy to achieve heating function, while induction cooker is relatively complicated, it first converts electric energy into magnetic field energy and then converts magnetic field energy into heat energy to achieve the purpose of heating, that is, through electronic control The circuit and coil generate an alternating magnetic field. When the bottom of the iron-containing pot is placed on the furnace surface, the pot cuts the alternating magnetic field line and generates an alternating current (ie, eddy current) in the metal part of the bottom of the pot. The eddy current makes the iron molecules of the pot High-speed irregular movement, molecules collide and rub against each other to generate heat energy. Both the electric furnace and the induction cooker have their own advantages and disadvantages. The advantage of the electric furnace is that the stove is directly heated, and the material requirements for the pot are not high. The disadvantages are: the safety is not high, it is easy to burn the human body, and the heat utilization efficiency is relatively low. , there will be heat loss during the heat conduction process; the advantages of the induction cooker are: the stove itself does not generate heat, is clean and safe, and has high heat utilization efficiency. The disadvantage is that there are strict requirements on the quality of the pot, which can only be iron or pot The bottom is made of iron material, and there will be a small amount of electromagnetic leakage around the bottom of the pot during use, which will affect people's health. It is these deficiencies that greatly limit the use and promotion of each in daily life. the

Contents of the invention

The object of the present invention is: to provide a kind of induction cooker that is suitable for pottery, glass or metal pot, and it is not only suitable for the pot that magnetic conduction material is made, and also is suitable for the pot that non-magnetic conduction material makes, and is easy to use and reduces A new type of induction cooker with electromagnetic leakage. the

The present invention is achieved in the following way: an induction cooker suitable for pottery, glass or metal pots, including a bottom shell, a surface shell, a heat conduction plate, a microcrystalline panel, a coil plate and a control device, and also made of stainless steel or aluminum The annular heat conduction disk, the microcrystalline panel is embedded in the central hole of the annular heat conduction disk, the upper surface of the microcrystalline panel and the upper surface of the annular heat conduction disk are on the same plane; the coil disk is under the microcrystal panel and the diameter of the coil disk is equal to or smaller than a microcrystalline panel;

The annular heat conduction disk is fixedly connected with the top opening of the face shell.

The above-mentioned electromagnetic cooker suitable for ceramic, glass or metal pans; its special feature is that: the electric heating element is an electric heating tube, the annular heat conduction plate is made of aluminum material, and the annular heat conduction plate wraps the electric heater Tube;

Or the annular heat conduction plate is made of stainless steel, and the electric heating tube is arranged on the lower surface of the annular heat conduction plate.

The electromagnetic cooker suitable for pottery, glass or metal pots; its special feature is that there is a heat-insulating mica layer on the inner ring platform and the center hole on the upper part of the inner ring platform;

The lower surface and the circumferential surface of the radial edge of the annular heat conduction disc cooperate with the mica layer.

The electromagnetic cooker suitable for ceramic, glass or metal pans; its special feature is that it also includes a temperature control device for a ring-shaped heat conducting plate, and one or more than two temperature sensors are arranged on the ring-shaped heat conducting plate, and the temperature sensor and Control device connection

The present invention is an electromagnetic cooker suitable for pottery, glass or metal pots. Due to the adoption of such a structure, when a metal pot is used, the coil plate and the electric heating element can be used to work at the same time, or one of them can be used for heating in different Phases are used alternately; pots made of non-magnetic materials, such as ceramic pots, casseroles, etc. can also be used for cooking food, and the heating ring is made of aluminum or stainless steel, which can shield the magnetic field around the bottom of the pot and reduce the magnetic field. Hazard to human body.
