Abstract:
The present invention relates to a polyphase electrical household appliance (1) for use in a three-phase electric power system. The household appliance (1) comprises load circuits (2), a power source unit (3) which has an input means that includes four or five terminals for respectively connecting the protective earth line (PE), the neutral line (N) and two phase lines (L1, L2) or three phase lines (L1, L2, L3) of the mains and an output means for outputting electric power via a plurality of output lines (L1', L2', L3', N') to the load circuits (3). The household appliance (1) of the present invention comprises: a protection unit (4) which detects the relative phases of the lines that are connected to the terminals of said input means assigned to the phase lines (L1, L2, L3) of the mains, and controls said output means in accordance with the detection result.
Abstract:
A refrigerator and a control method for the same are disclosed. The refrigerator includes a storage compartment formed in a cabinet of the refrigerator by a fixed insulation wall, the storage compartment being provided with an access opening, a door rotatably provided to the cabinet to open and close the access opening, a drawer (50) provided in the storage compartment, a camera (70) fixed to a ceiling of the storage compartment to photograph both a region (a first region) for storing of food arranged in an external space of the drawer (50) in the storage compartment and a region (a second region) for storing of food arranged in an internal space of the drawer (50) in the storage compartment, and a controller to separate, through a capturing time of a picture containing both the first region and the second region, a portion for the first region (a first region picture) and a portion for the second region (a second region picture) from the picture to individually divide and store the first region picture and the second region picture.
