This mechanical movement leads to an opening of the closure element, for example a door by a certain amount.
  • the rope is preferably designed as a cable. This may consist of metal and / or plastic or plastic fibers or have these.
  • the present invention relates to a refrigerator and / or freezer with at least one appliance body, which is closed by at least one door or other closure element, such as a flap, a drawer or the like and one preferably designed as an electromechanical door opening aid Unit for automatically assisted opening of the closure element has.

  • the drive unit can be designed for example as an electromechanical unit and exert on the cable or the rope a tensile force, which leads to a mechanical movement of the opening unit and thus also to open the door.
  • the drive unit itself does not act directly on the closure element, but rather that this action on the closure element takes place through the opening unit and preferably through direct contact between the opening unit and the closure element.
  • the cable extends in sections or in total outside of the cooled interior and / or outside the heat insulation of the device.
  • the rope extends outside of a cooled by the device area.
  • a closing mechanism which performs an automatic closing of the door, so that it is excluded that the door accidentally remains open. This applies to all other types of closure elements accordingly. It is conceivable to use a closing damper unit, the closing of the closure element and in particular the door preferably supports or makes to the last degrees before reaching the closed position.
  • the closure element in particular the door handleless, that is, in particular without protruding handles or recessed grips or the like.
  • the device has at least one detection means, for example at least one sensor which detects a signal of the user and which is connected to the drive unit in such a way that the drive unit is set in operation upon detection of the sensor signal.
  • at least one detection means for example at least one sensor which detects a signal of the user and which is connected to the drive unit in such a way that the drive unit is set in operation upon detection of the sensor signal.
  • the drive unit then starts to move and in this way activates the opening unit via the at least one cable.
  • the user makes a pressure pulse on the appliance door or built-in appliances on the front of the furniture front and / or that a voice or noise detection is provided, which leads to an opening of the door and / or that another non-contact sensor is provided, for example, detects a movement of the user and then sets the drive unit in motion.
  • the drive unit and the opening unit are designed such that the door by a certain angular range z. B. in the range of 10 ° - 15 °, which may correspond to a gap width of about 10 cm, is opened without a force required by the operator.
  • This opening of the door in particular in the case of small angular ranges or starting from the closed position of the closure element, has the advantage that that the largest applied during the opening of the closure element force (magnetic force of the seal, closing force of the door closing damper, locking force of door hinges, cold-related vacuum forces) are overcome by the mechanism according to the invention, without the user would have to act.
  • the user can engage behind the closure element and then easily bring it into the desired opening position (eg 45 °, 90 °, 135 °).

  • the opening unit is designed such that it is arranged on the side facing away from the hinge of the closure element. It is conceivable that the opening unit exerts on the closure element a tensile or compressive force, which leads to an opening of the closure element.
  • the cable section connected to the drive unit always has the same length independently of the device design.
  • An adaptation of the total required cable length between the drive unit and opening unit is then achieved by a variably provided cable section which extends between the opening unit and a cable connector, which connects this cable section with the cable section leading to the drive unit.
  • the at least one drive unit is located on the outside or in the region of the outside of the device and preferably on the rear side of the device.

It can be provided at any point one or more detection means which detect a user input to the opening of the closure element. These detection means may be implemented as one or more sensors detecting any conceivable type of user activity, such as a voice signal, a movement, a pressure signal, etc.
  • the drive unit is preferably designed as an electromechanical unit and designed in a preferred embodiment with an electric motor and a winch and a cable drum. It is conceivable that the shaft of the electric motor has a worm which meshes with a worm wheel of the cable drum. During operation of the electric motor, the cable drum is thus set in a rotational movement and thus unwinds the cable, whereby a tensile force is exerted on the cable, which leads to a movement of the opening unit.
  • a deactivation of the drive unit is made, which causes the rope around the wound section can be unwound again, so that the starting position is reached again.
  • the unwinding of the cable from the cable drum or winch or the like can be achieved for example by one or more springs, which are preferably components of the opening unit.
  • the opening unit has at least one rack and at least one pivot lever, which preferably exerts an opening force directly or indirectly on the closure element.

  • a "slip clutch” is provided, which is to be understood that this connection between the rack and slide is solvable. This is the case in particular when the load condition in the region of the toothed rack and of the carriage exceeds a certain limit value. This applies to the case in which a tensile force is exerted on the carriage via the cable, a movement of the rack due to a mechanical locking of the door or the like is not possible and the mechanical connection between the rack and carriage is canceled.
  • This mechanical connection can consist of a latching connection or the like. In this case, the carriage is indeed moved, but this movement does not lead to a movement of the rack, since the mechanical coupling between the two elements is canceled.
  • the pivot lever has a toothing, which is in communication with a gear, which in turn is in engagement with the rack.
  • This gear can be arranged stationary and is set by the movement of the rack in a rotary motion. This rotational movement is transmitted to the pivot lever, which then swings out.
  • the pivot lever is designed to be pivotable via an axis fixedly arranged on the carcass.
  • the pivot lever can be directly associated with a fitting of the door or other closure element. It is conceivable that the pivot lever has a stop roller, which makes contact with the door or a stop of the door. It is also conceivable that the stop roller or another stop element is designed as an elastic element, so that a low-noise and damage-free operation of the door takes place.
  • the pivot lever or the said roller can act directly on the door or on a fitting arranged on the door fitting.
  • the arrangement of the opening unit relative to the closure element is arbitrary, as long as it is ensured that the door can be pushed or pulled.
  • the opening unit is arranged on the side facing away from the hinge side of the door above or below the door or the flap or other closure element, since the lever is the cheapest.
