AI Technical Summary
Technical Problem
In air-cooled refrigerators, the evaporator top takes a long time to defrost and moisture cannot be effectively expelled, leading to the problem of secondary frosting.
Method used
A first air inlet duct, a second air inlet duct, and an air outlet duct are provided on one side of the freezer compartment, which are connected to the evaporator compartment. A first heater and a second heater are provided at the top and bottom of the evaporator, respectively. The valves and fans are controlled by the control unit to achieve heating of both ends of the evaporator and moisture discharge.
Benefits of technology
It shortens the defrosting time of the evaporator, avoids the circulation of moisture inside the chamber, and reduces the occurrence of secondary frosting.

Abstract
The application discloses a defrosting structure and method of an air-cooled refrigerator, wherein the defrosting structure of the air-cooled refrigerator comprises a freezing chamber, a first heater, a second heater, a first temperature sensing unit and a control unit, a rear wall of the freezing chamber is provided with an evaporator chamber, one side of the freezing chamber is provided with a first air inlet duct, a second air inlet duct and an air outlet duct which are communicated with the evaporator chamber, and the evaporator chamber is provided with an evaporator; the first heater is located at the top of the evaporator and corresponds to the position of the first air inlet duct; the second heater is located at the bottom of the evaporator and corresponds to the position of the second air inlet duct; the first temperature sensing unit is arranged on the surface of the evaporator; and the control unit is electrically connected with the first temperature sensing unit, the first heater and the second heater. The application sets the heaters at the top and bottom of the evaporator, so that the defrosting time of the evaporator is reduced, and the humidity in the evaporator chamber is discharged through the air outlet duct, thereby avoiding secondary frosting.
