  • Publication number: 20100005678
    Abstract: An exhaust air dryer includes a process airflow entering from outside as supply air, which removes moisture from laundry introduced in a treatment compartment and which emerges to the outside as exhaust air through an air outlet, a heat exchanger between the treatment compartment and the air outlet, seen in the airflow direction, which removes heat from the process airflow, while forming condensate, a dispersal device arranged downstream of the treatment compartment in the airflow direction and in front of the air outlet, which adds at least part of the formed condensate to the exhaust air, and a hydrophilic body belonging to the dispersal device, which projects into the process airflow and is impinged upon by condensate.

  • Publication number: 20090320312
    Abstract: A dryer includes a drying chamber, a process air guide that guides process air along the articles to pick up humidity from them, a heat sink in the process air guide that precipitates humidity from the process air as a condensate, and a condensate collector with a condensate container having an insert that is permeable to the condensate and that projects through an opening into the condensate container for transferring the condensate to and from the condensate container. The insert includes a first filter that filters particles from the condensate prior to storing the condensate in the condensate container.

  • Publication number: 20090113740
    Abstract: A dryer with a drying chamber that includes a process air duct for guiding process air through the drying chamber, a heat pump with a heat sink in the process air duct and through which air can flow in an outlet air direction for cooling down the process air, and a heat source arranged in the process air duct and through which air can flow in an inlet air direction for heating up the process air. The outlet air direction and the inlet air direction are substantially parallel to one another. The heat sink and the heat source are in a plane substantially perpendicular to the outlet air direction and to the inlet air direction alongside one another.

  • Patent number: 7356944
    Abstract: A drying rack for the stationary drying of articles to be dried, which can be installed in the drum of a clothes dryer. The articles can be knitwear or shoes that must not be moved when dried even when the drum turns. For articles, especially, wool articles, to dry faster, the drying rack has at least two spaced-apart surfaces disposed one on top of the other on which the articles to be dried can be spread, thereby substantially enlarging the surface of the articles to be dried. As such, the drying air current can better remove the moisture and larger individual wool articles can be dried in the clothes dryer.

  • Patent number: 7213348
    Abstract: A burner for a gas dryer is made up of a mixing tube having an open end for admission of gas fuel into the mixing tube. At least one other opening proximate to the open end serves to admit air into the mixing tube for mixing the air and the gas fuel. A burner head is located at an end of the mixing tube opposite the open end for allowing a mix of gas fuel and air to be discharged and be ignited into a flame. A baffle is attached to the burner at the base of the burner head and extends radially outward therefrom to prevent disruption of combustion of the gas fuel and air mixture as a result of secondary air being drawn outside and along the length of the mixing tube from the open end thereof toward the burner head. An air heater assembly for gas dryer includes combustion chamber having an air inlet and an air outlet for allowing air to flow therethrough and be heated for being passed over clothes to be dried in a drum of a dryer.
