Embodiment Construction

[0031] Embodiments of the present invention will now be described in detail, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to like elements throughout. The embodiments are described below in order to explain the present invention by referring to the figures.

[0032] figure 1 is a schematic diagram showing a control system of a refrigerator according to an embodiment of the present invention. Such as figure 1 As shown, first to third storage compartment temperature sensors 104a, 106a and 108a and an external temperature sensor 110 are electrically connected to an input side of the control unit 102 to control the operation of the refrigerator. The first to third storage compartment temperature sensors 104a, 106a, and 108a detect the internal temperatures of the first to third storage compartments 104, 106, and 108, generate electrical signals having magnitudes corresponding to the detected temperatures, and generate the ...

Abstract

A refrigerator including a plurality of storage chambers, a valve including at least one inlet port and a plurality of outlet ports to supply refrigerant to the storage chambers, respectively, and a control unit to control the valve such that only one of the outlet ports is constantly opened when the refrigerant is supplied to at least two of the storage chambers.

Description

technical field [0001] The present invention relates to a refrigerator and a method of controlling the same, and more particularly, the present invention relates to a refrigerator having a mechanism capable of controlling supply / interruption of fluid by rotating a rotary valve using a stepping motor to open or close an outlet. Valve, and method of controlling such a refrigerator. Background technique [0002] Generally, a refrigerator is a device that keeps food fresh for a long time. Therefore, the temperature of the storage compartment of the refrigerator is maintained at a suitable temperature for keeping food fresh. Some refrigerators have two or more storage compartments, which control a refrigeration cycle to satisfy different cooling conditions required by each storage compartment. This type of refrigerator includes a refrigeration passage control valve for controlling a refrigeration cycle, thereby satisfying different cooling conditions ...
