Problems solved by technology

To remove frosted ice, the heater can be run periodically, but running the heater too often consumes energy
In addition, the heat generated by the heater raises the temperature inside the storage chamber, which may cause the food to deteriorate.
In addition, in order to reduce the temperature raised by the heater, it is necessary to operate more compressors, which has the problem of increasing the energy consumption of the compressors.

Embodiment Construction

[0037] Generally, a refrigerator is a food storage space that can block heat entering from the outside by a cabinet and a door that are filled with insulating materials inside, and is provided with an evaporator and a drain that absorbs heat inside the food storage space. A freezing device composed of a heat sink that collects heat outside the food storage space, keeps the food storage space in a low temperature temperature area where microorganisms are difficult to survive and multiply, so that the stored food can be stored for a long time without changing its texture. device.

[0038] The refrigerator may be formed by separating a refrigerating chamber storing food in a temperature region above zero and a freezing chamber storing food in a temperature region below zero, and according to the configurations of the refrigerating chamber and the freezing chamber, refrigerators are classified into configurations with an upper freezing chamber and a freezing chamber. Top Freezer r...

Abstract

The invention relates to a refrigerator and a method for controlling the same. The invention provides a method for controlling the refrigerator, which is characterized by including a first step of heating an evaporator by continuously operating a heater configured to supply heat to the evaporator for supplying cool air to a storage compartment; and a second step of determining whether the time taken for the temperature of the evaporator to reach a predetermined temperature is within a predetermined time period, wherein in the second step, when the time taken for the temperature of the evaporator to reach the predetermined temperature is not within the predetermined time period, the heater is continuously operated in the same way as the first step, and when the time taken for the temperature of the evaporator to reach the predetermined temperature is within the predetermined time period, the heater is operated in a way different from the first step.

Description

technical field [0001] The present invention relates to a refrigerator and a control method thereof, and more particularly, to a refrigerator and a control method thereof for improving the reliability of defrosting or improving energy efficiency. Background technique [0002] Generally, a refrigerator includes a mechanical compartment formed at a lower portion of the body. In order to lower the center of gravity of the refrigerator, improve the assembly efficiency and reduce vibration, the mechanical room is usually arranged at the lower part of the refrigerator. [0003] A refrigeration cycle device is installed in the mechanical compartment of such a refrigerator, and the frozen / refrigerated state is maintained by utilizing the property of absorbing external heat when a low-pressure liquid refrigerant is changed to a gaseous refrigerant, thereby freshly storing food. [0004] The refrigeration cycle device of the refrigerator includes: a compressor, which converts a low-t...
