Description

Electric stove

[0001] This application is based on a Chinese patent application with an application number of 201810779530.9 and a filing date of July 16, 2018, and claims its priority. The entire contents of this application are incorporated herein as a whole.

[0002] Technical Field

[0003] The present application belongs to the field of electric heating technology, and in particular, relates to an electric flame stove.

[0004] Background Art

[0005] Currently, electric stoves are used as a source of energy to generate heat for heating. They are convenient and safe and are widely used in various fields. There are mainly three types of electric heating cookers: 1. Induction cookers; Induction cookers use electromagnetic induction In principle, the surface of the induction cooker is a heat-resistant ceramic plate, and a pot made of ferromagnetic material is placed on the heat-resistant ceramic. A coil is placed below. The control circuit of the induction cooker generates an alternating current flowing through the coil to generate a magnetic field. The magnetic field lines pass through the iron. The bottom of the magnetic pot, the bottom of the ferromagnetic pot will generate eddy current, which will cause the bottom of the pot to quickly generate heat and achieve high temperature, to achieve the heating function. 2. Electric ceramic stove; Place the resistance wire in the lower part of the cooker. After the resistance wire is energized, it will generate high temperature, and the high-temperature resistance wire will glow. The bottom of the cooker will be heated mainly by heat radiation. 3. Halogen lamp stove; a halogen lamp is placed in the lower part of the cooker, and the halogen lamp emits infrared heat radiation when it is energized to heat the item.

[0006] However, the existing electric heating cooker has the following problems: 1. The principle of electromagnetic heating requires that the cooker must be made of ferromagnetic material, otherwise the heating function cannot be achieved, there are restrictions on the material of the cooker, and some cooking forms cannot be achieved (such as Some cooking methods using ceramic containers cannot be heated by induction cookers). In addition, the bottom of the ferromagnetic cooker can only generate heat when it is directly facing the upper part of the coil. There is no heat generation in the other parts of the cooker without the coils facing directly, which leads to insufficient heating uniformity of the cooker. It is cold and has an effect on cooking. The “fire pot” that does not reach gas heating has a very uniform heating effect. 2. The electric ceramic stove and the Nansu lamp stove both use the heat radiation method to heat the pot. Although these two heating methods have no restrictions on the material of the pot, they can heat pots of various materials, including ceramic containers, but radiant heating. The method is still very different from the traditional gas flame heating method, and it can not achieve a very uniform heating effect of the traditional fired "fired pot".
