What's the problem with the oven?
Choice of appearance.Shape. Should be selected new, beautiful and reasonable structure. No deformation, smooth surface, no sag. The paint layer without peeling, no scratches, no wrinkle, no scratches.Inner housing and hardware. Should be burr free, smooth handle, bright plating, no rust, no trace or lack of plating.Box door. The box door should be well switched, airtight and without sticking. Springs should work when closed. Door frame should not be deformed, toughened glass should be no flaws, no cracks, transparency should be high.Electrical performance. The knob of the temperature regulator, timer and power selector switch should be firmly installed, the rotation should be flexible, and the mark of the knob should respond to the quasi functional grade. Power plug, power cord should be firm, without breakage. The electric heating element and the porcelain insulating seat shall be installed securely, and the wall of the electric heating element shall not be in contact with the tube wall. Check whether or not the metal electric heating pipe coating is peeling or bruised. Quartz heating tubes should be bright, with small bubbles or gas lines inside, and shall be free of cracks and cracks.Electrify examination. When the electric oven is powered on, first see if the indicator light is on, then switch the switch to various positions to observe the heating of the electric heating element. Finally check the timer travel time, although the timer does not require as accurate as the watch, but the error should not be greater than the soil 10%. And there is no "parking stop" phenomenon. If the electric oven temperature regulator, the regulator is adjusted to 200 DEG C, power supply is switched on within 20 minutes, the electric oven should be able to reach the set temperature, automatically cut off power supply, indicator lights, electric oven shows good performance.
Selection of types.The simple type electric oven: the biggest advantage of simple type is relatively cheap, but not a lot of this type with a timing device, the operation is troublesome, need to look at the time of baking food and baking time control. In addition, the electrothermal element of the simple electric oven is a metal electric heating tube. The electric heating tube mechanical strength and oxidation resistance is good, but relatively poor penetration, warming.Full function electric oven: the full function electric oven generally refers to the general type or advanced type electric oven. The electric oven is equipped with timing device and power shift device, so it is easy to use. The electric heating element of this electric oven is two kinds of metal electric heating tube and quartz electric heating tube. The quartz electric heating tube has the advantages of rapid heating, penetrating power and electricity saving, but the mechanical strength is poor, the body is brittle, and it is easy to crack when colliding. The fully functional electric oven is more expensive than a simple electric oven.Electronic oven: electronic oven is the latest emerging high-end products. It can change the heating method, heating time and food rotation according to the pre programmed procedures. The range of roasting is wider, the roasting effect is better, and the utility model is suitable for families with higher consumption levels.
Selection of power.The market generally electric oven power is generally between 500-1500W. When purchasing, you should consider the ampere value of the household electric meter first. The greater the amperage, the greater the optional power. In the range allowed by the meter, and then consider the number of family population, the population is small, should choose 750W below the electric oven; population of more than 750W can choose more than the electric oven.
