Kitchen things: three principles of electric oven purchase

Using the oven, we can make roast chicken, roast duck, baked bread, cakes, etc. With the improvement of living standards, many friends are willing to buy one, to add some fun to the plain life. Electric ovens can bring great convenience to our lives. What should we pay attention to when shopping? Will you choose the oven that suits your family? Here the author summarizes some of the common sense of the oven, if you have a plan to buy the oven recently, it may wish to take a look at the following text.

1. The choice of electric oven power.

The common electric oven power in the domestic market is generally between 500-1500 watts. When purchasing, you should first consider the amperage value of your household meter. The larger the amperage, the greater the available power. Within the allowable range of the electricity meter, consider the situation of the family population. If the population is less, it is better to use the electric oven below 700 watts; if the population is more, use the electric oven with more than 700 watts.

2. The choice of type of electric oven.

(1) Simple electric oven. For the average family, the biggest advantage of the simple type is that the price is cheaper, but this type does not have a timer device, it is cumbersome to operate, and people need to take time to observe the food baking and control the baking time. In addition, the electric heating element of the simple electric oven is a metal heating tube. This kind of electric heating tube has good mechanical strength and oxidation resistance, but its temperature rise is poor and its penetration is poor.

(2) Full-function electric oven. A full-function electric oven generally refers to an ordinary or advanced electric oven. This kind of electric oven has a timing device and a power shift device, which is easy to use. In addition, the electric heating element of this type of electric oven is two kinds of metal heating tube and quartz heating tube. The quartz heating tube heats up quickly, has strong penetrating power, and saves electricity; but its mechanical strength is poor, its body is fragile, and it easily breaks in collision. Full-function electric ovens are more expensive than simple electric ovens.

(3) Electronic electric oven. Electronic ovens are a high-end product that has recently emerged in the market. It can change the heating method, heating time, and food rotation according to pre-programmed procedures. A wider range of grilling, better baking effect, suitable for families with higher consumption levels.

3. The choice of electric oven appearance.

(1) Inner shell and hardware. Should be free of burrs, feel smooth, bright plating layer, no rust, no water marks or lack of plating.

(2) Doors. The door should be opened and closed smoothly without any jams. Springs should work when closing. The door frame should not be deformed, and the tempered glass should be free from cracks and cracks, and the transparency should be high.

(3) shape. It is novel, beautiful and reasonable in structure. No deformation, smooth surface, no depressions. The paint layer did not fall off, no scratches, no wrinkles, and no bumps.

(4) Electrical performance. The knobs of the temperature regulator, timer, and power selection switch should be firmly installed and the rotation should be flexible. The marking of the knob should be aligned with the function level. Power plug, power cord should be strong, no damage. The electric heating element and the porcelain insulating seat should be installed securely, and the wall of the electric heating element should not be in contact with the pipe wall. Check the metal heating tube coating for peeling or bruising. The quartz heating tube should be bright, and there should be small bubbles or gas lines inside, and there should be no damage and cracks.

(5) Power check. After the electric oven is powered on, first see if the indicator light is on, then turn the switch to each position to observe the heating of the heating element. Finally check the timer travel time, although the timer is not required to be as accurate as the watch, but the error should not be greater than 10% of the soil. And there can be no "stolen" phenomenon. If the electric oven has a temperature control device, the regulator can be adjusted to 200 °C, within 20 minutes of power supply, the electric oven should be able to reach the set temperature, automatically cut off the power, the light goes out, indicating that the electric oven work well.
