One, simple household electric oven
This is a product in the early market. Its structure is equipped with sheet like far-infrared radiant electric heating element or electric wire in the shell made of metal sheet, with a double layer plate made of thin plate, directly connected to the 220V power supply, the power can not be adjusted, the temperature can not be controlled. When the food is baked, it can only master the time according to experience, or use it from time to time. The way to cut off electricity is to grasp the heat and not to use it conveniently. In 2013, these products have been phased out.
Two. Ordinary household electric oven
It is a common variety in the market in 2013, including automatic temperature regulation, automatic timing and automatic temperature regulation timing products. This kind of oven is mainly composed of box, inner cavity, heating element, temperature controller, timer, and power supply wire, baking pan, baking net, handle fork and other accessories. The surface of the shell is painted with amino baking paint, and the inner cavity is loading and unloading. Both sides of the rack can adjust the height of the baking tray and the baking net as required. Most of the furnace doors adopt spring structure, and the middle is equipped with heat-resistant toughened glass transparent windows. The heating element is useful for metal tubular heating elements, and also has a heating element for opaque quartz glass. It also has flaky far-infrared radiation heating elements. The temperature controller on the panel is the control system of the oven, and the red and green indicator displays its working state. The temperature controller adopts bimetallic temperature control elements, and the timer is generally mechanical. Some electric ovens also have power conversion switches, which can control the surface fire and primer separately and get different heat.
Three. High level household electric oven
This advanced electric oven was rarely seen in the market in 2013. It is different from ordinary electric ovens: the structure is more rigorous, the appearance is more beautiful, the function is more complete. The shell is made of stainless steel sheet and is made of three layers and double cavities, so that the temperature of the shell is greatly reduced. In control, in addition to the function of the ordinary electric oven, there is also a low temperature gear with a temperature of only 36 degrees centigrade, which is specially used for yeast fermentation. It is equipped with coke crisp "strong" and "weak" switches to control the temperature fluctuation range and flexibly grasp the degree of crisp degree of baked foods. In addition, the timer can whistle in time to reflect the baking results in time.
