  • Patent number: 11530508
    Abstract: A drain system for a laundry appliance is provided. The laundry appliance may be configured as a clothes dryer having a heat exchanger to cool and condense moisture-laden air received from the laundry drum. The drain system utilizes a drain structure to catch condensate from the heat exchanger and evacuate the condensate to a sump area. A blower and blower channel moves the dry air from the heat exchanger back to the drum. To prevent negative pressure in the blower channel from moving the condensate to the sump area, an air channel between the blower channel and sump area provides air flow communication.

  • Patent number: 11501985
    Abstract: A low surface tension liquid supply unit supplies a low surface tension liquid onto the upper surface of a substrate to form a liquid film of the low surface tension liquid on the substrate. An opening is formed in a central region of the liquid film of an organic solvent. The liquid film is removed from the upper surface of the substrate by expanding the opening. While a low surface tension liquid is supplied from the low surface tension liquid supply unit, to the liquid film, toward a liquid landing point set outside the opening, the liquid landing point is moved so as to follow the expansion of the opening. While an facing surface of a drying head faces a dry region set inside the opening to form a low-humidity space between the facing surface and the dry region, with the low-humidity space having a humidity lower than that outside the space, the dry region and the facing surface are moved so as to follow the expansion of the opening.
