Abstract: A refrigerator includes a cabinet, a door opening/closing the cabinet and having an opening that is penetrated in a front/rear direction, a transparent panel assembly mounted to cover the opening and through which the inside of the refrigerant is seen, and a lighting member provided in the door or the cabinet to brighten a rear side of the transparent panel assembly. The transparent panel assembly includes a front panel defining an outer appearance of a front surface, a rear panel defining an outer appearance of a rear surface, a spacer made of a metal material and disposed between the front panel and the rear panel to define a periphery of the transparent panel assembly. A heater mounting part on which a heater is mounted is disposed on the spacer, and when the heater generates heat, one side of the front panel, which comes into contact with the spacer, is heated.

Abstract: A robot cleaner according to an embodiment of the present invention comprises: a travelling part for moving a body; a memory for storing travel state information of the traveling part, which is recorded while a cleaning operation is performed on the basis of a first map; and a control part for discriminately detecting a first area and a second area divided from a plurality of cleaning areas corresponding to the first map, on the basis of the stored travel state information. Moreover, the control part may generate a second map by removing one of the first area and the second area from the first map, and then control the travelling part to perform a cleaning operation in a changed cleaning mode on the basis of the generated second map.
