  • Publication number: 20100132215
    Abstract: In a mixer, in particular a tumbling mixer, the components to be mixed often still have to be dried during mixing, therefore the wall portions of the mixer are air permeable for force inducting drying air. In order to operate such a mixer contamination free for the ambient, it is proposed to cover the portions of the mixer with permeable walls on the outside with a cover, in particular a flexible foil, which is held tight at the mixer above and below the air permeable portions, so that drying air can be inducted between the foil and the mixer into the air permeable portions. Subsequently, the contaminated foil and the drum are provided to reprocessing or disposal.

  • Patent number: 6446357
    Abstract: A method and apparatus for controlling the drying cycle of a dryer by utilizing fuzzy logic control. Control is accomplished by first monitoring the moisture level of a clothes load in the dryer. From the monitored moisture information, variables such as the elapsed time from the start of the drying cycle to a point when no significant moisture is detected for a specified time period and the number of times higher moisture registrations occur during another specified time period are determined. Based on the determined variables, fuzzy logic is used to determine characteristics particular to the clothes load being dried, such as size of the load. Using the determined characteristics in conjunction with user settings more accurate control of the time of drying heat application, reduced drying heat application and cool down time can be accomplished.

  • Patent number: 6158148
    Abstract: The method detects impermissible operating states in a hot-air clothes dryer with a laundry drum. The temperature in the incoming air flow is detected periodically downstream of an incoming air heater and upstream of the drum. A differential value (difference value or gradient) is formed from two successively detected values. The differential value is compared with a predetermined differential value, and if the newly formed differential value is absolutely greater than the predetermined differential value, then a counting value is incremented by one step. The counting value is compared with a predetermined counting value and, if the current counting value is greater than the predetermined counting value, then the heating of the dryer is turned off and/or an operating state display is activated.

  • Patent number: 6067729
    Abstract: A shoe bar is useful for drying shoes in a conventional clothes dryer. The shoe bar has a relaxed length that is equal to or slightly greater than the inner diameter of the drum of the clothes dryer. The bar ends are inserted into the shoes. The bar is manually bent and placed in the drum. One shoe is placed against the drum inner diameter, and the other shoe is placed proximate the drum diametrically opposite the first shoe. The bar is released. The elastic material exerts a restoring force that tends to return the bar toward its relaxed configuration. The bar is too long to relax completely, so it remains at a working configuration whereat it urges the shoes against the drum. The shoes remain pressed against the drum, so they do not tumble when the clothes dryer is operated to rotate the drum.
