Abstract

The present invention discloses a refrigerator and relates to the technical field of refrigerators. The refrigerator is invented to settle problems, such as increased external space occupied by a refrigerator when its secondary door is opened, increased difficulty in fetching goods in the refrigerator, and heavy loss of cooling capacity resulted from the full opening of an opening. The inventive refrigerator comprises a main door; an opening is formed on a door body of the main door; a guide rail is provided at an edge of the opening, and a secondary door is fitted on the guide rail; and the secondary door is connected with a driving mechanism which can drive the secondary door to slide along the guide rail, and as the secondary door slides along the guide rail, the secondary door can enclose or open the opening. The refrigerator of the present invention is used for preserving and freezing foods.
