Common sense of microwave oven purchase

The advantages of microwave oven, such as time saving, energy saving and cleanliness, have aroused many people's interest and are increasingly favored by consumers. But there are many kinds of microwave ovens on the market at present, so how can we choose a satisfactory microwave oven? Generally, you can choose according to the following steps.

1. Choice of brand and specification.

Microwave oven is a product with high technical requirements, so the brand is very important when choosing microwave oven. For example, Galanz microwave ovens are backed by powerful technical force, advanced detection means and excellent after-sales service, so it is safe to buy products of this brand. In terms of specifications, the current market procurement is mainly concentrated in 700-900 watts. Generally speaking, 700 watts is enough for a family of 2-3 people, and 800 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 coordination of parts. Modeling is to see whether the product is beautiful and generous; The color depends on whether the product is in harmony with other appliances in the kitchen. The surface quality requires that the product surface has no mechanical bumps and scratches; The panel should be flat, with uniform color and good luster.

As a new type of kitchen cooker, microwave oven fully embodies its unique advantages in food thawing, fast food processing, food heating, tableware disinfection, etc., and adapts to the needs of fast-paced life of modern urban consumers, and is increasingly favored by consumers, so it is very popular in the market. In this microwave oven craze, 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 complicated market, various brands, specifications and prices, consumers are often at a loss. Which is more suitable for family needs?

For ordinary consumers, the choice of microwave oven should be based on personal economic situation, use environment and purpose, that is, from the perspective of practicality.

The first is the function of the microwave oven. For most urban residents, heating the lunch of working children 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, choosing a single-function ordinary microwave oven can be said to be really cheap and 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 family life. In short, the choice of functions should be adapted to personal living habits, consumption level, cooking time and energy.

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 650 ~ 800 W is enough for a family of 3 ~ 4. If you need to cook food quickly in your life, you should choose a microwave oven larger than 800W W, and the power of microwave oven with barbecue function is generally between1000 ~ 2500 W. When choosing, you should consider whether the household electric meter and circuit can withstand it. For example, if the rated current of an electric meter is 5A, the maximum working current it can withstand is twice that of 10A, and the maximum power it can withstand is 2200W(220V× 10A). The microwave oven with output power of 850W and rated power consumption of 1350W can be safely used. If the meter is 3A, it is obviously difficult to use. 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 of poor power selection.

In addition, the volume of microwave oven cavity is also one of the considerations. Big size means big power. If the family does not have much demand for cooking large-volume food, 18 ~ 25 liters 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" to verify whether the product directly goes from the production line to the store.

-Whether there are instructions and recipes (usually recipes), warranty cards and warranty cards in the outer packaging box.

-Whether the load-bearing plate (usually glass plate), grill (microwave oven with "barbecue" function) and other accessories are complete, and whether they are placed in the box or 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 sprayed layer is uniform, flat and smooth.

-It is necessary to see the product signboard on the external surface of the product or after opening the oven door. The main contents shall at least include: product name, product trademark, product model, product manufacturer's name, rated voltage (e.g. 220V), rated power (e.g. 1250W), rated power (e.g. 50Hz), rated microwave frequency (e.g. 750W), rated microwave power (e.g. 2450MHz) and rated electric heating element power (e.g. 65450w).

-On the outer surface of the product or after opening the oven door, you should also see some safety precautions.

-The signboard looks waterproof, the words are clear and wear-resistant, and the adhesion between the signboard and the product surface is firm.

-The design, scale and handwriting on the control panel should be clear and clearly defined.

-Turn the timer knob of the electromechanical microwave oven, and there is no obvious sense of stagnation. When turning to the highest or lowest scale position, it must be in place and cannot "cross the line". Set the timer to zero and you can hear a slight bell.

-The appearance is angular, and there should be no burrs on both metal and 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 for many times, and there should be no card leakage. According to the common design requirements of the oven door, the oven door should automatically pop open at a certain angle (about15-30) after pressing the door opening button. In order to meet this requirement, the oven door should shake slightly after opening, but it should not feel too shaken.

-There are two common oven doors: one is to open directly; One is to open the door by opening the door button.

When the former opens the door, it should feel a little hard; When closing the door, you should also use a little force to close it; When the latter presses the door-opening button hard, the door will spring open by itself, and the door will be closed just like the former.

-Microwave ovens do not rely on the complete sealing of doors and doorframes to prevent 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. This is normal. But if the gap is too big (for example, a nickel can be put in), it is not normal. In addition, after the door is closed, pushing the door hard will have a slight shaking feeling, but the shaking amount should not be too large. Then, with the help of the salesman, turn on the microwave oven, put a glass 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: set the power regulator to the highest power position and the timer pointer to the position of 10, and the microwave oven will start. About 5 minutes, open the oven door and touch the glass. It should be hot or boiling (depending on the power and water volume of the oven). Then adjust the power regulator to the gears of medium power, half power and "unfreeze" respectively, and work for 1-2 minutes. You should feel that these microwave ovens are "on and off". In view of the different connection positions of furnace lamps in electric furnaces, the turn-on time and turn-off time of lamps in various microwave ovens may be different when microwave ovens are working: some lamps are turned on when working, and turned off after opening the door; While others do the opposite. Users don't know how the lights are connected, but through the operation in the selection, as long as the lights are turned on and off regularly instead of randomly, they should be considered normal. When the microwave oven is working, the glass turntable in the oven cavity rotates, and there should be no stop-and-go phenomenon, no loud noise and no squeaking. At present, in order to prolong the life of the magnetron and increase the speed of the fan motor, 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. After the microwave oven is started every time, the rotating direction of the plate is random. This is determined by the characteristics of turntable motor, which is a normal phenomenon.

C. Computer-controlled microwave oven: Turn on the power supply, press the control button, and the display screen should have a clear, rapid and definite response. The operating procedure of computer-controlled microwave oven is quite complicated. With the help of sales staff, several commonly used programs can be tested to verify whether various working modes of microwave ovens are normal.

D microwave oven with "barbecue" function: turn the control button to "barbecue" to start the microwave oven. After about 5- 10 minutes, you should see the red light from the electric heating element above the oven cavity. Some functions of "microwave" and "barbecue" in a microwave oven with "barbecue" function can work at the same time, while others can work alternately. You also need to check these functions according to the instructions in the manual with the help of the sales staff. Other aspects of inspection are the same as those of mechanical microwave ovens and computer-controlled microwave ovens.
