Description

Single System Refrigerator

technical field

The invention relates to a refrigerator, in particular to a single-system refrigerator.

Background technique

Traditional single-system refrigerators utilize mechanical knobs to control the temperature in the refrigerator compartment. However, this temperature control method can only control the temperature of the refrigerator compartment and the freezer compartment at the same time, and cannot separately control the temperature of the refrigerator compartment and the freezer compartment. The mechanical knob used to control the temperature only has gears indicating the approximate range of the temperature. Therefore, this method of temperature control has low precision and large temperature fluctuations, which is not conducive to food storage. In addition, single-system refrigerators controlled by mechanical knobs are greatly affected by ambient temperature during use, and users need to manually adjust the refrigerator gear according to seasonal changes. In summer, due to the high ambient temperature, the user needs to lower the refrigerator gear by himself. Otherwise, if the refrigerator is still at a high temperature, it will be difficult for the refrigerator room to drop by one degree due to the large temperature difference between the refrigerator room and the refrigerator room. The loss of cold air will also become faster, which will cause the compressor to start for a long time and stop for a short time, and even cause the compressor to not stop, which will not only consume electricity but also shorten the service life of the compressor, and even freeze the refrigerator. Phenomenon. In winter, due to the low ambient temperature, if the refrigerator is still in a low gear, the compressor will not start due to the small temperature difference between the interior and exterior of the refrigerator compartment, which will cause the freezer to thaw. Therefore, although the cost of the traditional mechanical temperature control single-system refrigerator is low, the control method is complicated, which is not conducive to the user's use.

In view of the above problems, it is necessary to provide a new single-system refrigerator to solve the above problems.
