  • Malfunction preventing device for refrigerator and method thereof
    Patent number: 8109106
    Abstract: The present invention relates to a malfunction preventing device and a method thereof, which ignores an input signal produced by electricity capacity variation because of moisture to prevent a malfunction of a refrigerator. A malfunction preventing device for a refrigerator includes an inputting part in which a static electricity switch is provided to produce an input signal, and a controlling part that ignores a first input signal inputted in a wait mode, wherein there is no inputted signal from the inputting part for a predetermined delaying time period in the wait mode. A method for preventing a malfunction of a refrigerator includes performing a wait mode in that there is no input signal produced by static electricity for a predetermined delay time period, and ignoring a first input signal inputted in the wait mode.

  • Refrigerant valve control device and control method thereof
    Patent number: 8104301
    Abstract: The present invention relates to a refrigerant valve control device and a control method thereof, which adjusts eccentricity of a refrigerant valve during an operation of a refrigerator to prevent overcooling. A refrigerant valve control device of a refrigerator includes a temperature sensing part that senses temperature inside the refrigerator; a refrigerant valve that selectively opens and closes a refrigerant path; and a controlling part that controls the refrigerant valve based on temperature differences between the sensed temperature inside the refrigerator and a predetermined control temperature. In another aspect of the present invention, a control method of a refrigerant valve for a refrigerator includes determining whether refrigerant is leaked at a refrigerant valve based on temperature differences between the temperature inside the refrigerator and a predetermined control temperature; and controlling the refrigerant valve based on the result of the determination.
