There are two kinds of household ovens: small desktop ovens and embedded ovens.
Desktop oven
The advantage of desktop oven is that it is very flexible, and you can choose ovens with different configurations according to your needs. Due to different quality and configuration, the price ranges from several hundred yuan to several thousand yuan. Foreign brands are usually more expensive, while domestic products are more cost-effective. Many foreign brands are also OEM in China. It is recommended to choose the "non-greasy liner" model, which is cleaner after long-term use.
Embedded oven
The other is the embedded oven, which is an upgraded version and the ultimate version of the small oven. Because of its high power, fast baking speed, good sealing (generally sealed with rubber gasket), good heat insulation (heat insulation with three layers of tempered glass) and accurate temperature control, it is loved by more and more people. At the same time, due to the pursuit of health in 2007-20 13, more and more middle-class families noticed this problem and began to eat their own baked food because there were too many food additives in the cake shop outside.

The embedded oven can have no lower heating pipe and no independent temperature control. There is hot air circulation on the right side of the oven to make the biscuits crisp, but it is more suitable to use an air oven. Straight pipes are more uniform than curved pipes, and not all embedded ovens can bake double layers. The bigger and more uniform the oven, the higher the success rate.

frequency of utilization
Generally, it can be divided into three types: automatic control (timing, temperature adjustment and power adjustment), temperature control timing type and ordinary simple type.
Temperature control timing type is enough, because this type of function is more complete and cost-effective; Three-control automatic type, various baking functions are complete, but the price is more expensive; Ordinary and simple products are "entry-level" products, which are relatively cheap. However, due to the manual control of temperature and time, users need to carefully grasp the baking temperature to avoid the food being "raw" or over-baked, which will affect the taste. [2]
Food weight
The capacity of the electric oven is generally between 9 liters and 60 liters, so the purpose of buying the electric oven must be fully considered when choosing the capacity specification. The lower the power, the better. The higher the power, the faster the temperature rises, and the less the heat loss, but it will save electricity. Household electric ovens should generally choose 1000 watts or more.
Internal and external quality
A good electric oven should be sealed to reduce heat loss. The oven door is mostly open up and down, 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 by forcibly opening it; Not too loose to prevent accidental falling off during use. The more barbecue plates and grills in an electric oven, the better.
The electric oven is an electric appliance whose temperature suddenly rises, so it is required to use thick and safe materials. The products of high-quality oven materials need to use two layers of glass, as well as 0.5mm thick cold-rolled plate or stainless steel panel materials with high industry standards. High-end products must 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 the set temperature, it will stop working and continue heating when it is lower than the temperature. If you want to control the temperature, you can only switch it on and off manually every few minutes.
