  • Patent number: 8469043
    Abstract: The present invention describes a drying system for a dishwasher having a washing tub (2). The drying system comprises: a first fan (3) for propelling a first air stream through the washing tub (2) to an air transporting space (9) situated in the dishwasher outside the washing tub (2), wherein the first air stream is propelled in such a way that humidity in the washing tub (2) is absorbed by the first air stream and propelled to the air transporting space (9); and a second fan (4) for propelling a second air stream received from an area outside the dishwasher to the air transporting space (9). The drying system is further arranged such that the first and the second air streams are mixed in the air transporting space (9), and in that the mixed air stream is propelled to an exhaust opening (10) leading out from the dishwasher. Thereby, an efficient drying process can be achieved wherein air leaving the dishwasher has an appropriate temperature and humidity.

  • Publication number: 20100051070
    Abstract: The present invention deals with a dishwasher comprising a tub (2) for receiving at least one object that is to be washed, wherein the tub (2) has a tub bottom (7) that is downwardly inclined from a first portion of the tub (2) close to a first side (6) of the tub towards a second portion of the tub (2) close to a second side (5) of the tub, which second side is opposite to the first side, such that a distance (D) between the tub bottom (7) and a plane comprising an upper edge (11) of the tub increases towards the second portion of the tub. Thereby, it will be possible to receive large items in the tub, such as plates with a large diameter, without increasing the total height of the dishwasher. The invention is especially advantageous in drawer dishwashers, and when the tub bottom (7) is downwardly inclined from a front portion of the tub towards a rear portion of the tub.
