The entire contents of this application are incorporated herein as a whole.

[0003] 本申请属于电加热技术领域, 尤其涉及一种电加热装置和电焰灶。  [0003] The present application belongs to the technical field of electric heating, and in particular, relates to an electric heating device and an electric flame stove.
[0004] 背景技术  [0004] Background Art
[0005] 目前采用电作为能量来源产生热能用来加热的灶具, 具有方便安全等特点在各 种领域得到广泛应用, 电加热灶具主要有 3种类型产品: 1、 电磁灶; 电磁灶采 用电磁感应原理, 电磁炉的炉面是耐热陶瓷板, 铁磁材质锅具放置在耐热陶瓷 上, 下面放置线圈, 电磁灶的控制电路产生交变电流流过线圈从而产生磁场, 磁场的磁力线穿过铁磁材质锅具底部, 铁磁锅底会产生渦流, 令锅底迅速发热 产生高温, 实现加热功能。 2、 电陶炉; 在锅具的下部放置电阻丝, 电阻丝通电 后发热产生高温, 高温电阻丝发热发光, 主要以热辐射形式加热锅具底部。 3、 卤素灯灶; 在锅具的下部放置卤素灯, 卤素灯通电后发光产生红外热辐射原理 , 加热物品。  [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] 但现有的电加热方式的灶具存在以下问题: 1、 电磁加热原理要求锅具必须采 用铁磁材质, 否则不能实现加热功能, 对锅具材质有限制, 一些烹饪形式不能 实现 (比如采用陶瓷容器的一些烹饪方式不能用电磁灶加热) 。 另外铁磁锅具 底部只有正对线圈上部的位置才能产生热, 锅具其它地方没有线圈正对就不会 产生热量, 导致锅具加热均匀性不够, 容易出现锅具有些地方高温, 有些地方 却是冷, 对烹饪产生影响, 达不到燃气加热的“火包锅”非常均匀加热效果。 2、 电陶炉和南素灯灶都是通过热辐射的方式来加热锅具, 这两种加热方式虽然对 锅具材质没有限制, 可以加热各种材质的锅具包括陶瓷容器, 但是辐射加热方 式和传统的燃气火焰加热方式还是有很大的不同, 也不能做到传统燃气加热的“ 火包锅”非常均匀的加热效果。  [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".
