Before this application, the temperature in the cold storage space of a refrigerator was the same, while the optimal storage temperature and humidity for different foods were different, causing users to dare to put some low storage temperature ready-to-eat, tropical fruits into the refrigerator. The food can not be eaten immediately when the temperature is too low, and the user can only put the food outside; the tropical fruits need to be stored in an interval of 8-10 ℃ for the best storage time and are not dare to be placed in a refrigerator. The food put into the refrigerator is not in the optimal temperature range, the food decays fast, and the waste is serious. The embodiment of the invention can freely adjust the temperature of each storage space refrigerated by the refrigerator according to the requirements of users, so that food is stored in the optimal storage space, and the users are guided to correctly place the optimal storage space for the food. Every storing space 21 all has self independent air-out and independent return air, and every storing space 21 can both realize the many grades of changes of temperature, freely switches.

Further, when the number of gear commands in each gear command group is large, for example, each target temperature in the storage space 21 changes by one degree centigrade, the gear commands can be used as a new gear. This may also be referred to as stepless gear adjustment. For example, there may be 11 steps between 0 ℃ and 10 ℃, so that each storage space 21 may be adjusted to any temperature between 0 ℃ and 10 ℃. Of course, only three ranges of 0 ℃ ice temperature area, 4 ℃ golden area and 10 ℃ hot band fruit area can be arranged between 0 ℃ and 10 ℃.

Thus, it should be appreciated by those skilled in the art that while a number of exemplary embodiments of the invention have been illustrated and described in detail herein, many other variations or modifications consistent with the principles of the invention may be directly determined or derived from the disclosure of the present invention without departing from the spirit and scope of the invention.
