1. Selection of brands and specifications.
microwave oven is a product with high technical requirements, so the brand is very important when choosing microwave oven. For example, Galanz microwave oven is backed by strong technical force, advanced testing means and excellent after-sales service, so it is safe to buy this brand of products. In terms of specifications, the current market purchases are mainly concentrated on 7-9 watts. Generally speaking, 7 watts is enough for a single family of 2-3, while 8 watts is more suitable for families with more than 4 people.
2. Selection of product appearance quality.
the choice of appearance includes modeling, color, surface quality and the coordination of parts. Modeling is to see whether the product is beautiful and generous; Color depends on whether the product is coordinated with other appliances in the kitchen. The surface quality requires that the product surface has no mechanical bumps and scratches; The panel shall be flat, uniform in color and good in luster.
As a new type of kitchen cooker, microwave oven is increasingly favored by consumers because it fully embodies its unique advantages in food thawing, fast food processing, food heating and tableware disinfection, and meets the needs of fast-paced life of modern urban consumers, so it is very popular in the market. In this upsurge of microwave ovens, many manufacturers have taken various promotional measures in order to seize market share, which is of course very beneficial to consumers. However, in the face of the complicated market, a variety of brands, specifications and prices, consumers are often at a loss. Which one is more suitable for family needs?
For ordinary consumers, choosing a microwave oven should be considered comprehensively according to personal economic situation, use environment and purpose, that is, focusing on the practicality of choosing a microwave oven.
first, the function of the microwave oven. For most urban residents, the lunch heating for the children of dual-income workers and the elderly is their main function, which is also the biggest advantage of microwave ovens. Considering the above consumption trends, if families with average economic ability have no special requirements for food cooking and operation methods, choosing a single-function ordinary microwave oven can be described as real and cheap, and it can fully meet the needs of daily use. Of course, if the economic conditions are good, you can choose some multifunctional microwave ovens, which also needs to consider the frequency and dependence of various functions in your family life. In short, the choice of functions should be adapted to personal living habits, consumption level, time and energy used for cooking.
the power of microwave oven is its main performance, and it is also a key factor to be considered when purchasing. Usually we refer to the microwave output power. The higher the microwave output power, the stronger the heating ability and rapidity. Generally speaking, a microwave oven of 65 ~ 8 W is enough for a family of 3 ~ 4. If you need to quickly heat and cook food in your life, you should choose a microwave oven larger than 8W W. The power of microwave oven with barbecue function is generally between 1 ~ 25 W, and whether the household electric meter and circuit can withstand it should be considered when selecting. For example, if the rated current of an electric meter is 5A, the maximum working current it can withstand is twice that of 1A, and the maximum power it can withstand is 22W(22V×1A). Choosing a microwave oven with an output power of 85W and rated power consumption of 135W can be used safely. If the electric meter is 3A, it is obviously very difficult to use, and if other electrical appliances are used at the same time, it will not work at all. The power parameters of the microwave oven must be carefully checked when purchasing, so as not to affect the use because the power problem is not well selected.
In addition, the cavity volume of microwave oven is also one of the considerations. Large volume means large power. If there is not too much need for cooking large-volume food in the family, 18 ~ 25 liters of volume is more suitable for general families.
How to judge the quality of microwave oven
1. Appearance quality
Basically, every consumer will first evaluate the appearance of the product to be purchased.
-whether there is dust-proof packaging (plastic bag) after unpacking, and whether the packaging is flat and "submissive", so as to verify whether the product is directly delivered from the production line to the store.
-whether there are instructions and recipes in the outer packing box (usually there are recipes), guarantee cards and warranty cards.
-whether the accessories such as bearing plates (usually glass plates) and grills (only available in microwave ovens with "barbecue" function) are complete, and whether they are put in the box or in the furnace cavity through anti-collision measures.
-whether there are obvious scratches on the outer surface of the product and the inner surface of the furnace cavity, and whether the spray coating is uniform, flat and smooth.
-product signs will be seen on the external surface of the product or after opening the oven door, which is necessary. Its main contents should at least include: product name, product trademark, product model, product manufacturer name, rated voltage (such as 22V), rated power (such as 125W), rated power (such as 5Hz), rated microwave frequency (such as 75W), rated microwave power (such as 245MHz), rated electric heating element power (such as 1W, with only).
-you should also see some safety precautions on the outer surface of the product or after opening the oven door.
-the signboard looks to have certain water resistance, clear words and wear resistance, and the adhesion between the signboard and the product surface has certain firmness.
-the pattern, scale and handwriting on the control panel should be clear and have clear boundaries.
-turn the timer knob of the electromechanical microwave oven, and there is no obvious feeling of sticking. When it is turned to the highest or lowest scale position, it should be in place and cannot "cross the line". Turn the timer to zero and you can hear a slight bell ring.
-there should be no burrs on the edges and corners of the appearance, whether metal parts or nonmetal parts.
2. Intrinsic quality
-The oven door is an important barrier to prevent microwave leakage, which should be inspected emphatically. Open and close the door several times, and there should be no card leakage. According to the common oven door design requirements, the oven door should automatically bounce open at a certain angle (about 15-3) after pressing the door opening button. In order to meet this requirement, there should be a slight shaking after the oven door is opened, but there should be no feeling of too shaking.
-there are two kinds of common oven doors: one is to open them directly; One is to open the door by opening the door button.
When opening the door, the former should feel that it can only be opened with a little force; When closing the door, you should also use a little force to close it; The latter presses the door opening button hard, and the door will bounce open by itself, while the door closing is the same as the former.
-The microwave oven does not rely on the complete sealing between the door and the door frame to stop the microwave leakage. Therefore, after the door is closed, there is a certain gap between the door and the door frame, which can transmit light and leak air, which is normal. But if the gap is too large (such as a nickel can be put in), it is not normal. In addition, after the door is closed, there will be a slight shaking feeling when you push the door hard, but the shaking amount should not be too large. Then, with the help of the salesman, turn on the microwave oven, put a cup of cold water in the oven cavity, close the door, and conduct further inspection and selection according to the following steps:
A. Mechanical microwave oven: turn the power regulator to the highest power position, and the timer pointer to the position of about 1 minutes, and then the microwave oven will start. About 5 minutes, open the oven door and touch the glass, which should be hot or boiling (depending on the power of the stove and the amount of water). Then, turn the power regulator to the middle power, half power, "thaw" and other gears respectively, and work for 1-2 minutes each. You should feel that the microwave ovens in these gears have the phenomenon of "on and off". In view of the different connection positions of the furnace lights in the electric furnace, when the microwave oven works, when it turns on and when it turns off in various microwave ovens may be different: some lights turn on when working, and then turn off when the door is opened; While others are the opposite. Users don't know how to connect the lights, but through the operation in the selection, as long as the furnace lights are turned on and off regularly rather than randomly, they should be considered normal. The glass turntable in the oven cavity rotates when the microwave oven is working, and there should be no stop-and-go phenomenon when it rotates, and the sound should not be too loud, and there should be no squeaking noise. At present, in order to improve the life of magnetron, the speed of fan motor is increased, so the fan noise is slightly increased, but it is controlled within a reasonable degree. Through this measure, the life of magnetron, the heart of microwave oven, has been greatly improved.
B. The rotation direction of the plate is random after the microwave oven is started every time. This is determined by the characteristics of turntable motor, which is a normal phenomenon.
C. Computer-controlled microwave oven: Turn on the power, press the control button, and there should be a clear, rapid and definite response on the display screen. The operating procedures of computer-controlled microwave ovens are rather complicated. With the help of salespeople, several commonly used procedures can be tested to verify whether the various working modes of microwave ovens are normal.
D. microwave oven with "barbecue" function: turn the control button to "barbecue" and start the microwave oven. After about 5-1 minutes, you should see the red light emitted by the electric heating element above the oven cavity. Some of the functions of "microwave" and "barbecue" in the microwave oven with "barbecue" function can work at the same time, and some can work alternately. It is also necessary to check these functions with the help of the salesperson according to the instructions in the manual. Other aspects of inspection are the same as those of mechanical microwave ovens and computer-controlled microwave ovens.
