  • Publication number: 20150308725
    Abstract: An ice-making device for a refrigerator or freezer comprises: an ice-making tray having an upper side, a lower side, a longitudinal direction and a transverse direction of said tray, wherein said ice-making tray is mounted so as to be rotatable about a first axis of rotation which is parallel to the longitudinal direction of the tray; a collecting container arranged underneath the ice-making tray for catching ice which falls out of said ice-making tray when the latter is in an emptying rotational position; a wall structure which, when the ice-making tray is in an ice-making rotational position, delimits a first air duct which runs underneath said ice-making tray and is open towards the underside of said tray, wherein said first air duct runs in the longitudinal direction of the tray and extends over substantially the entire length of the ice-making tray, wherein the wall structure has at least one wall element which, when the ice-making tray is in the ice-making rotational position, projects into a falling tr

  • Patent number: 9062911
    Abstract: A refrigeration device is provided that includes two housing parts in the form of a body and a door that together delimit an interior. A seal is fastened to one of the housing parts and sealingly contacts the other housing part when the door is closed and a drive element is arranged to drive the door from the closed position into an open position. A sensor detects a movement of the door and a control circuit coupled to the sensor activates the drive element when a movement of the door is detected.

  • Patent number: 7726754
    Abstract: The invention relates to a refrigerator having two movably connected housing parts that delimit a heat-insulated interior and a seal member that is fastened to a first of the housing parts and contacts the other of the housing parts in an airtight manner in the closed disposition of both housing parts. A lifting element lifts the seal member from a contact surface on the second housing part to permit pressure compensation between the inner chamber and the surroundings of the refrigerator. The lifting element is at least in part formed by a thermally deformable material and, in a first shape thereof, it establishes a sealed contact between the seal member and the contact surface, and in a second state resulting from the effect of heat or cold, it lifts the seal member from the contact surface in order to ensure pressure compensation.

  • Publication number: 20090039751
    Abstract: A method for operating a refrigerator having two movably connected housing parts, a frame and a door which jointly delimit a heat-insulated interior, as well as a seal that is fastened to a first of the housing parts and contacts the other of the housing parts in an airtight manner in the closed position of both housing parts. The method includes a step in which the airtight contact between the seal and the second housing part is prevented for a specific period of time along a section of the seal while the sealing contact between the seal and the second housing part is subsequently restored along said section of the seal in a step. The invention also relates to a refrigerator for carrying out the method.

  • Patent number: 6939024
    Abstract: A work surface lighting arrangement for lighting the work surface under an extractor hood, such as a cooking surface in a kitchen area. The lighting arrangement includes at least two lights in the hood with one light being user activated and the second activated by operation of the hood. The lights can include a dimming function and the second light can be activated with the hood exhaust fan. The second light also can be activated only after activation of the first light.

  • Patent number: 6878175
    Abstract: A grease filter made from metal, in particular, for use in commercial kitchens and in household vapor extractor hoods has impact filter elements with a first row of elongate profiles disposed at distances from one another and with a second row of profiles disposed at distances from one another, the profile rows being at a distance from one another and being offset relative to one another such that the profiles of the second row match with the distances between the first row. A knitted fabric filter or an expanded mesh grid is disposed between the first and second rows of profiles. The profiles have a sound-absorbing material, in particular, sound-absorbing mats, on a side facing away from the air flow. By virtue of this configuration, a high grease efficiency is achieved, there is excellent protection against flame puncture, and noise protection measures can be implemented.
