1. First, it is necessary to know what the oven is for. If it is only used to roast chicken wings, peanuts, melon seeds and other small things, of course, there is no need for an oven with too large a volume, which is small and cheap enough to cope with. If you want to roast the whole chicken, you should choose an oven with a rotating shaft in the middle of the oven, which can be heated conveniently and evenly. If you want to bake a bigger birthday cake, of course you need a bigger oven.

2, different types should be clearly seen

There are also many types of ovens on the market now, including mechanical, electronic, timing controlled, timing temperature adjustable, and three-control automatic electric ovens and so on. The so-called three-control oven can adjust temperature, time and change power. This kind of electric oven is very convenient to use, but the price will be relatively high. Everyone must choose to buy an oven that suits them according to their own economic ability.

3. The size and power should be clearly defined.

The specifications of electric ovens are divided by power, which generally ranges from 5 to 2 watts. In order to meet the basic baking requirements, at least 9 watts should be selected. High-power electric ovens have the advantages of fast heating, less heat loss and less power consumption, especially three-control electric ovens, and it is better to buy high power. But when buying an oven, you should also consider the endurance of the wires in your home. Don't blindly pursue high power, but you can't work normally when you get home.

4. Pay attention to some details

Power-on test Plug in the selected oven, first check whether the power indicator light is on, and then test whether the oven heats up quickly enough. The oven needs to be preheated before baking food, so the faster the preheating time, the more energy will be saved. The oven with good quality takes only 1-2 seconds, while the oven with poor quality takes 7-8 seconds. Finally, it is necessary to test whether the upper and lower heating rods work normally.
