What is 123456 in the refrigerator for?

The refrigeration capacity is large, and the temperature in the refrigerator is lower than 1 when the thermostat is turned to 6. On the temperature control knob of the refrigerator, 1234567 indicates the seven grades of temperature from high to low. The bigger the number of gears in the refrigerator, the colder it is. The bigger the number, the lower the temperature. Temperature adjustment should be adjusted according to the season. Generally speaking, the colder the weather (winter), the greater the adjustment range (5.6), and the hotter the weather (summer), the smaller the adjustment range (2.3). Generally, the middle tune (3.4) is better in spring and autumn. If the ambient temperature is low in winter, it is best to turn on the winter temperature compensation switch at the same time, but don't forget to turn off this switch when the temperature gets warmer, otherwise it will consume a lot of electricity. Extended data 1. The common refrigeration temperature of food in the refrigerator is 4 to 8℃. In this environment, the growth rate of most bacteria will slow down. But some bacteria are psychrophilic, such as Yersinia, Listeria, etc., which can grow and reproduce rapidly at this temperature. If you eat food infected with this kind of bacteria, it will cause intestinal diseases. 2. The temperature of the freezer of the refrigerator is generally around-18℃. At this temperature, ordinary bacteria will be inhibited or killed, so the food stored in it has better preservation effect. But freezing does not mean that it can be completely sterilized, and some bacteria with strong freezing resistance will still exist.
