There are 4 principles of purchasing.

Choose a brand: If you don't know, it's best to choose a more influential brand to reduce the risk of shopping.

Practicality: It is not suitable for small household appliances that belong to the "painting snake to add to the foot", such as "refrigerator protector", "TV life extender", "visual screen", etc., which are small household appliances with use, which will reduce the reliability of major appliances.

Safety: The safety of small household appliances is generally poor, when purchasing, it should be noted that the power cord must be double-layer insulation, in addition, the packaging should be strict, the marking should be regular, the seismic resistance is good, and so on.

Haier, Meiling, Siemens, Rongsheng, and Xinfei on the market are all very good. We buy refrigerators mainly for refrigeration and freshness. Therefore, the first thing is to choose the capacity according to the number of refrigerated items in the household.

Generally, 172 litres is very suitable for ordinary families. Second, we need to look at its energy efficiency identification card to see how much electricity it consumes. Of course, the less power consumption, the better.

What checks should I do when buying a refrigerator?

1) Check the appearance of the refrigerator and first look at the door. The door should be square, not skewed and deformed, and the surface of the box should be smooth and undamaged. Then look at the condenser, capillary, compressor, etc. behind the box for external injury, whether the pipeline is flattened, whether there are oil stains or desoldering places in the weld joint, etc.

2) Check whether the door seal of the refrigerator is tight, and clamp the paper strip in the door crack of the box door while closing the door, if the paper strip is clamped tightly and will not slip off by itself, it means that the magnetic door seal of the refrigerator is good.

3) Check that the bulb in the refrigerator is intact, and open the door after the refrigerator is powered on, and the light will be turned on immediately; Close the refrigerator door and the light should turn off automatically.

4) Check the compressor When purchasing a refrigerator, the most important thing is to observe the performance of the main components such as the refrigerator compressor. If allowed, two refrigerators can be powered on at the same time for a comparative check.

1) First check the starting performance of the compressor. When the power is turned on, the refrigerator can start and enter operation; When the power is cut off, the refrigerator shuts down normally; When starting again, the compressor can start up within one second and operate normally, which indicates that the compressor has good starting performance. When the power is turned on, the compressor starts immediately, and then stops itself after about a few seconds, which means that the compressor has not entered the normal operation state and the compressor has poor starting performance.

2) Then check the refrigeration performance of the refrigerator. Turn on the power supply, run the refrigerator for about 20min, touch the condenser (the heat sink behind the box) by hand, if the upper part of the condenser is hot, and the lower part is cold, it means that the refrigeration system is normal.

What you should pay attention to when buying electrical appliances is: 1. Buy a brand. A good brand is established after years of market training, and the quality and service can stand the test.

2. Choose according to the population of the family. 3. See whether the function of the electrical appliances to be purchased is advanced and practical. 4. Choose the shape and style of electrical appliances according to personal preferences.

5. To buy conventional machines and best-selling products, you can't buy processed products, old products, and new products (processed products and old products are easy to stop production, and accessories may not be guaranteed after a long time) (new products have not been tested by the market, and the quality risk is greater) 6. Try to avoid buying samples (because there is an unwritten rule in the home appliance industry: return and exchange samples first, and dismantle the samples without accessories for the maintenance machine) (even if you have to buy samples, you must strictly test the machine on site, and take out the packing list to compare whether the accessories are complete) 7. Try to go to the brand** Merchants or wholesalers to buy, cheaper, service materials are more guaranteed 8, buy major appliances to shop around, it is recommended to choose the model in the big supermarket, understand, and then go to the brand ** business or wholesaler to bargain to buy (at least the basis of the lowest ** in the big supermarket can also be cut, or even lower).
