Key points when purchasing a microwave oven

1. Is it better to buy a high-power one or a low-power one? Which one is more power efficient?

Many people have the misunderstanding that a microwave oven with a high output power consumes a lot of power. As a result, if you want to save energy, buy a small one rather than a large one. However, the power consumption of a microwave oven is also calculated based on the microwave time, so in addition to the power, it also depends on the time it takes to completely cook the same food. Therefore, if you choose a microwave oven with a low power, it will take a long time to microwave food, which will not save electricity.

Practice has proven that using a high-power microwave oven to cook the same food not only saves time, but also saves electricity. Therefore, from the perspective of power saving, you should buy a large one rather than a small one.

2. How to detect the output power of a microwave oven

It is very simple and can be directly tested experimentally. Since the average microwave power output by magnetrons of different models and qualities is different, there is a gap between the actual output power of microwave ovens of many manufacturers and their nominal power, and some gaps are very large. Therefore, consumers are reminded to check the output power of the microwave oven when purchasing.

How to detect it? Here is a small method: Pour 2 liters of water into a plastic or glass container, first use a thermometer to measure the initial temperature, place it in the microwave, heat it for 2 minutes, take it out, measure the temperature immediately, and then multiply the difference between the final temperature and the initial temperature. Taking 35, the product is the output power of this microwave oven. Then compare the actual output power with the manufacturer's standard output power, and you will have an idea.

3. Clarify the relationship between rated power and output power

Usually the output power of a microwave oven is 50% to 60% of the rated power. The closer to 60%, the better the heating capacity. , so you should choose high rather than low when choosing. After mastering this point, if someone sells you a microwave oven with high output power, you can divide its output power by the rated power. If it is lower than 50%, don't mention it. If it is higher than 60%, it is not credible.

4. The choice of the appearance quality of the microwave oven is very important

Look at the shape and whether it is beautiful and elegant. The surface of the microwave oven should be free of mechanical bumps and scratches;

Looking at the panel, it needs to be smooth, the parts must be tightly matched, the color should be uniform, and the gloss should be good.

Look at the shell, check whether the shell and door are deformed, whether there are obvious gaps where the parts are closed, whether the door switch is smooth, and whether the contact with the shell is snug

Look at the door frame and glass , whether the door frame and door frame are broken or damaged, whether the door seal is intact and flat, and whether the window glass is damaged.

Look at the base and check whether the stability and flatness of the base are intact, whether the four legs of the microwave oven are flat on the glass plate, and whether there is any shaking or shaking.

5. Choice of microwave oven safety

The most basic requirement of a microwave oven is that it can withstand frequent use and high temperatures without deformation. When choosing a microwave oven, you can use your fingers to press every part of the door body. Open the oven door. The door of a good microwave oven has good hardness and cannot be pressed. There is no sound when pressing the oven door. The door opens and closes with a crisp "click" sound. Inferior microwave ovens are made of poor materials. The door body is mostly made of organic plastic and is single-layer sealed. It will loosen when pressed with your fingers, and you may even hear a "squeaking" sound. The microwave is prone to leaking after being used for a long time, which is very harmful to the human body.

6. The choice of brand price is crucial.

Microwave ovens are products with relatively high technical requirements, so it is best for consumers to choose well-known brand products. Currently, the safety of famous brand products on the market all meet national standards. Choose well-known brands with appropriate prices so that you can buy and use with confidence.
