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 forming a cabinet and a door filled with insulating material inside, and is provided with an evaporator that absorbs heat inside the food storage space and a discharge The freezing device composed of the heat sink that collects the heat outside the food storage space maintains the food storage space in a low-temperature temperature region where the survival and proliferation of microorganisms are difficult, so that the stored food does not change its texture for a long time. device.

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

Abstract

The invention relates to a refrigerator and a method for controlling the same. The invention provides a method for controlling the refrigerator, and the method is characterized by including: a first step of heating an evaporator by continuously operating a heater configured to supply heat of a fixed input value to the evaporator for supplying cool air to a storage compartment; 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; and a third step of operating the heater by providingan input value that is the same as an input value in the first step to the heater when it is determined in the second step that the time taken to reach the predetermined temperature exceeds the predetermined time period, and providing an input value that is smaller than the input value in the first step to the heater when it is determined in the second step that the time taken to reach the predetermined temperature is within the predetermined time period.

Description

technical field [0001] The present invention relates to a refrigerator and a control method thereof, and in more detail, to a refrigerator that improves reliability of defrosting or improves energy efficiency and a control method thereof. Background technique [0002] Generally, a refrigerator includes a machine room formed in a lower portion of a body. In order to lower the center of gravity of the refrigerator, improve assembly efficiency, and reduce vibration, the mechanical room is generally arranged at the lower part of the refrigerator. [0003] The mechanical room of such a refrigerator is equipped with a refrigeration cycle device, which uses the property of absorbing external heat when the low-pressure liquid refrigerant turns into a gaseous refrigerant to maintain a frozen / refrigerated state, thereby storing food freshly. [0004] The refrigerating cycle device of the refrigerator includes: a compressor, which converts the low-temperature and low-pressure gaseous ...
