1、电热管加热
1. Heating tube heating
电热管现在已经被广泛应用在蒸饭柜、热水器等厨房设备中。电热管是在金属管两端电极接人电阻丝,周周围空隙部分紧密填充具有耐热性、导热性和绝缘性的结晶氧化镁粉,通电后发热,经周围介质传导热量。管状加热元件具有结构简单,机械强度高,热效率高,安全可靠,安装方便,使用用寿命长等一些特点。
Electric heating tubes are now widely used in cooking equipment such as rice cooker, water heater and so on. The electric heating tube is the resistance wire at the two ends of the metal tube, and the crystallized magnesia powder with heat resistance, heat conduction and insulation is filled closely around the surrounding space, and the heat is transmitted through the surrounding medium. The tubular heating element has the advantages of simple structure, high mechanical strength, high thermal efficiency, safety and reliability, easy installation and long service life.
2、电磁炉加热原理
2. The heating principle of the electromagnetic furnace
电磁炉加加热原理就是将50Hz交流电转化为工作频率为20kHz左右的交流电,交流电在锅具底部生成交变磁场,金属锅具内产生涡流,高频涡流迅速导电发热,实现电磁能向热能的转换。
The heating principle of the electromagnetic furnace is to convert the 50Hz alternating current to the alternating current of about 20kHz. The alternating current generates alternating magnetic field at the bottom of the pot, the metal pot produces eddy in the metal pot, and the high frequency eddy current is rapidly conducting and heating, realizing the conversion of the electromagnetic energy to the heat energy.

3、远红外线加热原理
3, the principle of far infrared heating
远红外线是一种传导能量的电磁波,介于红色与不可见光谱之间,所以称为远红外线,波长在0.47~400?m之间。当远红外线线照射到被加热的物体时,一小部分射线被反射回来,绝大部分滲透到被加热的物体之中,当发射的远红外线波长和被加热物体的吸收波长一致时,被加热的物体内分子或原子吸收远红外线能量,产生剧烈的振动、旋转,并使内部分子和原子发生高速摩擦,产生热量而使其温度升高,从而达到了加热的目的。
Far infrared is an electromagnetic wave that conducts energy between the red and invisible spectra, so it is called far infrared, with wavelengths ranging from 0.47 to 400?M. When the far infrared line irradiates the heated object, a small part of the ray is reflected, most of which penetrates into the heated object. When the wavelength of the far infrared ray emitted is in accordance with the absorption wavelength of the heated object, the molecules or atoms in the heated object absorb the far infrared energy, producing violent vibration, Rotation, and make the internal molecules and atoms have high-speed friction, heat generation and its temperature rise, thus achieving the purpose of heating.
远红外线加热时不需要传热介质,其具有很强的穿透能力,远红外线加热与常规传导方式相比,具有热传导简单直接、热效率高的特点。可烧烤食物、杀菌消毒,具有快捷、卫生、质量佳、口感好等优点。
Far infrared heating does not need heat transfer medium, it has strong penetration ability. Compared with conventional conduction mode, far infrared heating has the characteristics of simple direct heat conduction and high thermal efficiency. It can barbecue food, sterilize and disinfect. It has the advantages of quick, hygienic, good quality and good taste.
