1. A refrigerated compartment with a temperature field dynamic control function, the refrigerated compartment comprising:
a compartment body;
a refrigeration mechanism that is fixed on a side wall of the compartment body and that is configured to inject cold air into the compartment body;
a plurality of steering mechanisms that is fixed on a top wall of the compartment body, wherein:
each of the plurality of steering mechanisms comprises a first steering gear fixedly connected to an inner side surface of the top wall of the compartment body and a second steering gear fixed on a connecting plate connected to an output shaft of the first steering gear,
an output shaft of the second steering gear is fixedly connected to a fan that is configured to accelerate the cold air flowing therethrough, and
the first steering gear drives the fan to rotate in a plane parallel to the top wall of the compartment body, and the second steering gear drives the fan to rotate in a plane perpendicular to the top wall of the compartment body, to realize a rotation of the fan towards any direction inside the compartment body in order to change a flow direction of the cold air; and
a plurality of temperature sensors that is installed on side walls of the compartment body and that is connected to a control mechanism arranged outside of the compartment body, the plurality of temperature sensors being configured to detect temperature in the compartment body and transmit information of the detected temperature to the control mechanism;
wherein the control mechanism is connected to the plurality of steering mechanisms, the fans, and the refrigeration mechanism, and is configured to control a working power of the refrigeration mechanism and an operation of the plurality of steering mechanisms and the fans according to information of the detected temperature.
