Energy-saving refrigerator

Abstract

The invention discloses an energy-saving refrigerator. Based on the traditional no-frost air cooling refrigerator, the energy-saving refrigerator also comprises a cold air inlet channel, a cold air outlet channel, an outdoor temperature sensor, an inlet channel air door, an outlet channel air door, and a refrigerator control panel, wherein the cold air inlet channel is arranged on the rear of a freezer of the refrigerator; two ends of the cold air inlet channel are communicated with the inside of the refrigerator and outdoor cold air, and one end positioned outside the refrigerator body is connected with the outdoor temperature sensor; the cold air inlet channel on the refrigerator body is provided with the inlet channel air door; the cold air outlet channel is arranged on a corresponding part of a bottom steel plate on the lower part of the refrigerator body; one end of the cold air outlet channel is communicated with the freezer, while the other end is connected with the outlet channel air door; the refrigerator control panel is connected with the outdoor temperature sensor, a refrigeration sensor, a freezing sensor, the inlet channel air door and the outlet channel air door; the refrigeration sensor is connected with a refrigeration air door; and the freezing sensor is connected with a compressor and a freezing fan. On the premise of ensuring food storage temperature, the energy-saving refrigerator fully utilizes ambient low-temperature cold sources so as to greatly save energy of the refrigerator and obviously reduce product noise.

Description

technical field [0001] The invention relates to an energy-saving refrigerator, which belongs to the technical field of refrigerator refrigeration air circuit circulation. Background technique [0002] Refrigerators are divided into two types: direct cooling and air-cooling. Air-cooling refrigerators use cold air forced circulation to refrigerate. An evaporator is installed inside the air-cooled refrigerator. The evaporator is usually of finned tube type. It is placed in the interlayer between the freezer and the refrigerator or at the upper back of the box. The cold air is sent to each position of the refrigerator to achieve the purpose of cooling. Since the evaporator is not in direct contact with the food, the heating system can be used to heat the evaporator for a short time, and the cooling will resume immediately after defrosting, so we cannot see what it is resulting frost. [0003] The direct cooling and frost refrigerator is to place the food directly on the surfac...
