What is the difference between electric porcelain furnace, light wave furnace and general resistance furnace?

In fact, you have answered more than half of the question yourself. Let me add the difference between the three. Ordinary electric furnace has low heat utilization rate and single function, which is not ideal. Both the wave oven and the electric porcelain oven can be made into multi-functions, such as frying, barbecue, hot pot, stir-frying, hot milk, soup, slow stew, reservation and so on. Optical wave furnace mainly emits light waves, with low power and small glare, but the temperature of furnace surface glass is low, and the risk of being burned after use is small; The electric ceramic stove mainly emits infrared light, which is not dazzling, and the temperature is high and fast, and the cooking effect is good, but it is hot after use.

Your mother probably took a fancy to the cooking function of the electric ceramic stove, so satisfy her!
