Title: Automatic floor cleaning method - using sensors to determine relative wall positions for real-time calculation of nested cleaning contours
Inventor: HWANG JIN SEONG
IPC: A47L5/12
Filed: 1993-03-06
Abstract: The floor cleaning is performed using the automatic cleaner which first moves from its rest position to a start position parallel to one wall and at a certain minimum distance from it. Then the cleaning is initiated with simultaneous acquisition of information on the positions of the other walls by means of machine-mounted sensors. This is to maintain the machine at a constant distance from the adjacent wall for this cleaning contour. On completion of this contour, a second contour within it is calculated and the machine is controlled to follow it. The process is repeated until the whole floor has been cleaned. Machine speed and direction is calculated from the relative wall distances by a "fuzzy logic" circuit. ADVANTAGE - Allows automatic cleaning without prior knowledge of room shape.

Title: Dishwashing machine with a washing container
Inventor: KAEFFERLEIN HEINZ
IPC: A47L15/42
Filed: 1993-03-31
Abstract: A dishwashing machine has at the bottom (2) of the washing container (1) a drainage trough (3) covered by a screening arrangement (4). A suction connecting branch (9) leads from this drainage trough to a circulating pump (10). In addition, through the screening arrangement (4), a bypass pipe (18) is drawn up out of the chamber (8) formed between the drainage trough and the screening arrangement (4) into the washing container (1). In order to achieve a reliable soiling-dependent control of the liquid supply to the machine, the chamber (8) is assigned a level sensor (15) which controls a renewed supply of liquid when the washing-liquid level falls below a predetermined chamber level (16). Operational pressure fluctuations in the chamber (8) are avoided by the bypass pipe (18) which ends directly below the passage point (20) through the screening arrangement (4). <IMAGE>
