1. Different uses

Microwave ovens are mainly used to heat food. There is a rotatable stirrer near the entrance of the cooking cavity. Because the stirrer is a fan-shaped metal, it reflects microwaves in all directions when rotated, so the microwave energy can be evenly distributed in the cooking cavity. Warm food. The power range of microwave ovens is generally 500 to 1000 watts.

An oven is an electric heating appliance that uses radiant heat emitted by an electric heating element to bake food. It can be used to make roast chicken, roast duck, bake bread, pastries, etc. According to the different needs of baked goods, the temperature of the electric oven can generally be adjusted within the range of 50-250°C.

2. Different principles

The principle of microwave heating is simply: when microwaves radiate to food, the food always contains a certain amount of water, and the water It is composed of polar molecules (the positive and negative charge centers of the molecule do not overlap even in the absence of an external electric field). The orientation of this polar molecule will change with the microwave field.

Due to this movement of polar molecules of water in food. And the interaction between adjacent molecules produces a phenomenon similar to friction, which increases the temperature of the water, therefore, the temperature of the food also rises.

Food heated by microwaves is also heated internally, so that the entire object is heated evenly and the temperature rises quickly. It heats food 5cm deep into the food at a frequency of 2.45 billion times per second, accelerating the movement of molecules.

Ordinary household electric ovens include automatic temperature adjustment, automatic timing and automatic temperature adjustment and timing products. This type of electric oven is mainly composed of a box, an inner cavity, a heating element, a temperature controller, a timer, and accessories such as power leads, baking sheets, grilling grids, and handles.

The surface of the shell is sprayed with colorful amino baking paint, and the inner cavity is removable. The grids on both sides can adjust the height of the baking tray and grilling net as needed. Most furnace doors adopt a spring structure with a high-temperature-resistant tempered glass transparent window in the middle.

Heating elements include metal tubular electric heating elements, opal quartz glass heating elements, and sheet-shaped far-infrared radiation electric heating elements. The temperature controller on the panel is the control system of the electric oven, and its working status is displayed by red and green indicator lights.

The temperature controller uses a bimetallic temperature control element, and the timer is generally mechanical. Some electric ovens also have a power conversion switch, and the surface fire and bottom fire can be controlled separately to obtain different heat levels. (Oven)

3. Different purchasing requirements

Basic requirements for purchasing a microwave oven:

1. Microwave ovens are included in the first batch of national mandatory safety products For products in the certification (CCC certification) catalog, consumers must choose products with the "CCC" certification mark and the corresponding factory code and certification certificate number when purchasing. In order to verify the authenticity of the certification mark and certification certificate, you can log on to the official website of the China National Certification and Accreditation Administration Commission to conduct an online query of the certification certificate.

2. Check whether the product’s instruction manual, certificate of conformity, warranty card and accessories are complete.

3. Carefully check the product’s logo and instruction manual. The national mandatory standard GB4706.21-2002 "Special requirements for the safety of microwave ovens for household and similar electrical appliances" stipulates.

The identification of microwave oven products should be clear and standardized, and the content should include: trademark, model, specifications (such as capacity), rated voltage, rated input power, symbol of power supply nature, name of the manufacturer, rated output power, etc. .

The instruction manual should have warnings to prevent misuse and detailed cleaning methods; the operating switch labels on the product should be clear and reliably fixed.

4. Check the appearance. The appearance should be flat and smooth, with uniform color and no obvious color difference. In addition, microwave ovens will produce microwaves. When purchasing, you should pay special attention to the sealing condition of the door and whether the door interlocking device is normal.

You should pay attention to the following points when purchasing an electric oven:

1. The thermal efficiency of an electric oven is greater than 60%.

2. The time for the inner cavity temperature to rise from room temperature to 200°C shall not exceed 15 minutes.

3. For an electric oven with automatic temperature control, the oven temperature should be adjustable within the range of 100 to 250°C, and the temperature control error should be less than ±10%.

4. For electric ovens with automatic timing control, the control time should be continuously adjustable from 0 to 45 minutes, and the travel time error should be less than ±10%.
