frequency of utilization

It is usually divided into three types: automatic control (timing, temperature adjustment and power adjustment), temperature control timing type and ordinary simple type. For ordinary families, it is enough to choose the temperature control timing type, because this type of function is more complete and cost-effective. If you are a family who likes baking food and often needs to use different baking cooking methods, you can choose the higher-grade three-control automatic type, which has all kinds of baking functions, but the price is more expensive. For families who only bake food by chance, the ordinary simple type is an "entry-level" product. It should be noted that although the price of this type of product is relatively cheap, because the temperature and time are manually controlled, users need to carefully grasp the baking temperature to avoid the food being "raw" or over-baked, which will affect the delicious taste.

Food weight

The capacity of electric ovens generally ranges from 9 liters to 60 liters (for home use), so the purpose of buying electric ovens must be fully considered when selecting the capacity specifications. If it is only used to bake bread for a family of three, 9 to 12 liters is enough; If you want to use it for a roast turkey dinner or a barbecue party, you should naturally choose a large-capacity product as much as possible. What needs special reminder is that the lower the power, the better. The high-power electric oven will save electricity because of its fast heating speed and less heat loss. Household electric ovens should generally choose 1000 watts or more.

"Internal and external" quality

A good electric oven should be well sealed first, so as to reduce heat loss. The oven door is mostly opened from top to bottom, so it is necessary to carefully test the lubrication degree of the box door. The door of the box should not be too tight, otherwise it is easy to burn people when you open it forcibly; It should not be too loose to prevent it from accidentally falling off during use. The more barbecue plates and grills in the electric oven, the better.

The electric oven is an electrical appliance with a sudden increase in temperature, so it is required that the oven be made of thick and safe materials. Products with high quality oven materials need to use two layers of glass, and the industry high standard 0.5mm thick cold-rolled plate or stainless steel panel materials. High-end products should have at least three baking tray positions, which can be close to the fire, close to the fire and located in the middle. In addition, whether the inside of the oven is easy to clean is also the focus of investigation.

Generally, the oven can't automatically adjust the temperature. The thermostat of the oven is an automatic switch. When it reaches its set temperature, it will stop working, and then continue heating when it is lower than the temperature. If you want to control the temperature, you can only turn it on and off artificially every few minutes.
