1: instead of buying a computer, buy a mechanical one (time-sharing). That is, it is regulated by 1234567.
2. Buy more than 500 yuan.
3. Choose a big manufacturer, because the big manufacturers specializing in the production of microwave ovens have mature production technology and are very particular about the choice of parts.
4: Don't buy Haier's.
In terms of use:
1: Try not to put the microwave oven in the kitchen, because the kitchen is greasy and humid, and the transformer in the microwave oven is easy to short-circuit and burn out.
Don't close the microwave oven immediately after use, wait for a minute or two. Because the hot air in the microwave oven should be dispersed before it is turned off, this can reduce the oxidation of the internal connector.
Also, it is best not to close the door after using the microwave oven, because it can reduce the wear of the door hook and even prolong the service life of the microwave oven.
4. Enamel metal containers and articles should not rotate in the cavity, because it will damage the magnetron.
Recommend Granger or mitsubishi electric, and remember to buy pure machinery above 500 yuan.
With these, I believe you can buy your favorite microwave oven.
