  • Patent number: 6966124
    Abstract: A drum washing machine, which has a clothes-drying unit with a plurality of heat pipes. The heat pipes recover, during a drying-mode operation of the drum washing machine, heat from high temperature humid air flowing from a water tub, and combine the recovered heat with low temperature dry air flowing from an area around a condensing nozzle, thus saving time and electricity during the drying-mode operation. In the clothes-drying unit, an air duct includes first and second duct parts, having a condensing nozzle installed in the first duct part, and a blower fan and a heater installed in the second duct part. A lower end of the heat pipe is arranged in a lower end of the first duct part, and an upper end of the heat pipe is arranged in an upper end of the first duct part. The heat pipe thus recovers the heat from the air, which flows in the lower end of the first duct part, and combines the recovered heat with the air, which flows in the upper end of the first duct part.

  • Patent number: 6643953
    Abstract: A clothes dryer in accordance with the present invention includes a drum rotatably supported in a case having an interior space for drying clothes. Air for drying clothes is supplied to the suction duct that is connected to one side of the drum. An extension duct extending from the suction duct into the drum supplies the air from the suction duct into the drum. An exhaust duct is connected to the other side of the drum for exhausting the air that is used to dry clothes to the outside of the case. The clothes dryer uniformly dries clothes inputted into the drum as the dryer directly transmits heated air to the center portion of the drum, thereby improving clothes drying efficiency.

  • Patent number: 6564470
    Abstract: An appliance for thermally processing granular material, especially for roasting food items such as coffee beans. The granular material lies on a perforated base through which gas flows upwardly to create a fluidized bed. The exhaust gas is fed to a cyclone separator for separation of entrained solid particles. Preferably, the base is located in an inner chamber which is at least partially enclosed in an outer chamber forming the cyclone separator. The exhaust gas is fed into a top opening of the outer chamber thereby providing a rotary gas flow. Alternatively, the base is located in an outer chamber in which at least the area above the base is designed as the cyclone separator. The outer chamber at least partially encloses an inner chamber through which gas is fed to create a rotary gas flow. In both cases, an extremely compact roaster design is realized.
