Abstract:
1. A dishwasher comprising: a washing basket; and a conduit system connected to the washing basket in an air-guiding manner such that air is guided from the washing basket to the conduit system and air is guided from the conduit system to the washing basket and the conduit system including a cold side portion and a hot side portion and including at least one horizontally arranged heat tube having a pair of ends, one of the ends of the heat tube extending into the cold side portion of the conduit system and the other end of the heat tube extending into the hot side portion of the conduit system and the conduit system being operable to guide air in a spiral pattern through the conduit system in cooperation with the horizontally arranged heat tube from the washing basket through the cold side portion, wherein the spiral pattern of the conduit system is configured to guide the air perpendicularly across the heat tube at least twice between the cold side portion and the hot side portion, whereupon the one end of the heat tube promotes a cooling of air in the cold side portion of the conduit system with a resultant condensing of moisture out of the cooled air, to thereafter guide cooled air from the cold side portion to the hot side portion, whereupon the other end of the heat tube promotes heating of the air in the hot side portion of the conduit system, and to thereafter guide such heated air from the hot side portion to the washing basket and the heat tube operating to conduct heat from its one end extending into the cold portion of the conduit system to its other end extending into the hot portion of the conduit system with the one end of the heat tube receiving heat from air guided therepast at the cold side portion of the conduit system and conducting such received heat to its other end.
