  • Patent number: 6739144
    Abstract: The present invention relates to an EMI reducing structure in a refrigerator. The present invention aims at minimizing electromagnetic waves radiated from a cable 60 for transmitting signals from a control unit 40 installed in a main body 20 of the refrigerator to a display unit 30 installed on a door 22. To this end, it is configured such that the cable 60 composed of a bundle of cables is put into a conductive shielding net 70 which in turn is connected to grounding portions 40g, 30g of the control unit 40 and display unit 30. At this time, both ends of the conductive shielding net 70 are fully connected to the grounding portions 40g, 30g, respectively. Further, the cable 60 wrapped with the conductive shielding net 70 is installed within a waveguide 50. In general, the waveguide 50 functions to shield electromagnetic waves of a high frequency band greater than a cut-off frequency varying according to its sectional shape.
