Abstract
The invention discloses an electric throttle control method for a refrigerator. The electric throttle control method for the refrigerator is characterized in that when a moving baffle of an electric throttle needs to be opened for the refrigeration of a compartment of the refrigerator, a CPU (Central processing unit) of a controller obtains the driving step number of a stepping motor inside the electric throttle according to the logic calculation, so that the moving baffle of the throttle is driven to operate to a corresponding position of 0-90 degrees. According to the electric throttle control method for the refrigerator, the moving baffle can be controlled to operate to different angles, and the air volume of the throttle can be controlled, so that the requirement on different refrigerating capacities under different working conditions of the compartment is met.
