The heating tube of the electric oven is very important. The function of the oven is to generate high heat to bake or dry things. Generally, the heating devices commonly used in electric ovens include stainless steel heating tube, resistance wire (electric heating wire) heater and quartz heating tube.
Let's take a look at the advantages of the three electric heating tubes.
1. Quartz heating tube: Generally, the object is heated by radiation, the heating is more uniform, and it does not contact the heated object, but it is difficult to heat locally; while the stainless steel heating tube is heated by heat conduction, which heats quickly and is not easy to be uniform, but can be locally heated. .
It can be said that the quartz tube heats up quickly, but its temperature drops quickly when the power is off, the life of the quartz tube is also short, and the impact resistance is also poor. That is to say, it will be damaged when touched, and its radiation ability is also worse than that of far-infrared heating tubes.
2. The heating effect of the resistance wire alone is the worst. The stainless steel heating tube is the best heating element. .
3. The best oven heating element belongs to the far infrared heater, but the far infrared heating tube is much more expensive than the above three electric heating tubes. If the quantity is small, the far infrared heating tube can be used without considering the price.
Among them, the stainless steel heating tube has the highest efficiency, and it is relatively convenient to replace and maintain. The other two have been used before, but they are rare now, and the efficiency is not as high as the first.
