The invention discloses an energy-saving refrigerator capable of automatically
defrosting. The energy-saving refrigerator comprises a refrigerator shell, a refrigerator is arranged in the refrigeratorshell, a
heat exchanger is arranged on the left side of the refrigerator, a freezing cavity is formed in the refrigerator shell, a
cold storage cavity is formed below the freezing cavity, and a freezing device is arranged on the left side of the freezing cavity; and the freezing device is provided with a
defrosting mechanism capable of preventing the freezing device from being frosted. The energy-saving refrigerator is simple in structure and easy and convenient to operate, when the energy-saving refrigerator is used, after a refrigerator door is opened, a lamp of a refrigerator can be turnedon, a
defrosting device is powered on to work at the moment, therefore
moisture, making contact with the cooling device, of the outside and
frost formed before are removed and used for refrigerationwork, and accordingly,
energy consumption of the refrigerator is reduced; and by means of the design, the refrigerator door can be automatically closed after a period of time, therefore the situationthat after the refrigerator is used, the door is forgotten to be closed, the
power consumption of the refrigerator is increased is avoided, and it is guaranteed that food in the refrigerator cannot gobad under the condition that the temperature rises because the door is not closed.
