Definitions

  • the present invention relates to a refrigerator and/or freezer with a body and a refrigerated interior therein, with two doors that open and close in opposite directions being arranged on the body, with the doors each having an end face that approaches one another when the doors are closed have and are arranged adjacent to each other.
  • Another problem is that when one of the two doors is opened slowly, the second door may also be opened unintentionally because the magnets do not separate.
  • the present invention is therefore based on the object of further developing a refrigerator and/or freezer of the type mentioned at the outset in such a way that leaks and noise generation as well as increased manufacturing and assembly costs attributable to a lack of tolerance compensation are avoided.
  • a sealing element is arranged on at least one of the front sides of the French door, which has a movable door seal, the sealing element having a movable force deflection element connected to the door seal, the force deflection element having a contact area on which when closing the door through the body, a force is exerted, and wherein the force deflection element is arranged such that this at said Application of force moves the door seal towards the face of the other door and/or alternatively moves towards the body.
  • the sealing element with door seal is a mechanical unit.
  • the sealing element is preferably screwed to the appliance door or connected to it in some other way and has the (at least one) door seal which is movable, e.g. pivotable, rotatable or displaceable, relative to the sealing element.
  • the sealing element is the holder or housing for the door seal.
  • the movement of the door seal is effected by the force redirecting element when a force is exerted on it. This action of force on the force deflection element is generated as soon as the force deflection element comes into contact with the body during the closing process of the door.
  • the force deflection element acts on the door seal in such a way that it is moved towards the other door and/or towards the body. This leads to the gap between the doors or the gap between the door and the housing being closed in a simple manner.
  • Each of the two doors preferably has such a sealing element.
  • the force deflection element is arranged and designed in such a way that the door seal is moved towards the body as well as towards the respective other door when the door is closed.
  • the contact area of the force deflection element can be designed as a projection, in particular as a pin. If the door is closed, the projection comes into contact with the body and in this way moves the force deflection element, which in turn exerts a force on the door seal and thus causes it to move.
  • a restoring element is provided which is in contact with the door seal and exerts a force on the door seal which is directed in the opposite direction to the direction of movement caused by the force deflection element.
  • the door seal is moved to its initial position, which it occupies when no force is being exerted by the force-reversing element, i.e. when the door is open. In this position the door seal is retracted relative to the body and/or relative to the other door.
  • the force deflection element is arranged and designed in such a way that it moves the door seal in two spatial directions. In the plan view of the door, movement can thus take place in the x and y directions, with the x direction being a direction to the side, i.e. towards the other door, and the y direction being a direction towards the body.
  • Both movements can take place simultaneously or one after the other.
  • the sealing element can have a front door seal and a housing-side door seal.
  • the front door seal is located between the doors when the doors are closed.
  • the door seal on the housing side is located between the door and the body.
  • Both Door seals can be formed by one and the same seal or by two separate seals.
  • a heating device is arranged on or in the sealing element and/or the door seal.
  • a first electrical contact can be arranged on the sealing element and a second electrical contact can be arranged on the body, the two contacts being arranged in such a way that they are in an electrically conductive connection with one another when the door is closed that current flows through the heater.
  • the invention also includes the use of only one force deflection element, of two or of more than two force deflection elements per door.
  • the force deflection element can be rotatably and/or displaceably arranged in or on the sealing element.

  • FIG. 1 shows a refrigerator-freezer combination with a refrigerator compartment K arranged at the top and a freezer compartment G arranged underneath.
  • the refrigeration part K has two doors 10, 20 which are hinged in opposite directions to one another and are each attached to the edges of the body, between which the gap 21 is located.
  • Both doors each have a sealing element 30 on their face side S, which is arranged opposite from the hinge side.
  • the sealing elements 30 are, for example, screwed to the outside of the doors 10, 20 and form their front edge.
  • body-side pin contacts are identified by the reference numeral 50 and contacts of the sealing elements 30 are identified by the reference numeral 60 .
  • the contacts 50, 60 are in an electrically conductive connection with one another, so that when the door is closed, current flows from a power source on the body side via the contacts 50, 60 into the sealing elements 30 and into the heater located therein.
  • a sealing element 30 is shown in a perspective view. It has a fixed part 31 arranged on the door and a magnetic door seal 32 with heating that can move relative thereto.
  • a force deflection element 70 is arranged in each of the sealing elements 30 both on the upper side and on the lower side (cf. FIG. 7).
  • This has a protruding pin 72 which points towards the body when the door is closed.
  • These pins 72 can also be seen from the view of the doors 10, 20 from the inside, ie from the cooled interior in FIG. 7a.
  • FIG. 7b shows the force deflection element 70 as such.
  • FIG. 7c shows a view of the doors 10, 20 from above.
  • FIG. 8a shows the two door seals 32 in a state in which they are spaced apart from one another at the front.
  • FIG. 8 b the gap between the doors is closed by the door seals 32 .
  • the area between the front edges of the doors is marked with an arrow.
  • Each of the door seals has an end area 33 and an area 34 on the housing side. These areas can be formed by one and the same or by two different door seals.
  • the pin 72 of the force deflection elements 70 strikes the front of the body. This leads to a rotational movement of the force deflection elements 70 in the respective sealing element 30.
  • the force deflection element actuated in this way acts on the door seals 32 in such a way that the sealing areas 34 on the housing side are pressed against the front of the body and that the sealing areas 33 on the front of both doors are moved toward each other so that the gap between the doors 10, 20 is closed.
  • FIG. 9 shows a perspective view of a sealing element 30 in which two spring return elements 36 are arranged. These act on the door seal in such a way that the door seal is moved into the retracted position shown in FIG. 8a when the door is open and on the force deflection element 70 no force is exerted. The force redirection element 70 is moved to its initial position, which it occupies when the door is open.
  • the sealing system has a mechanical unit with a movable seal with heating and magnet on both French doors. When the doors are closed, these two movable seals are pressed towards each other at an angle (movement in the x and y axis) via mechanical force deflection from the housing at the top and bottom and thus seal the two doors from one another and also from the housing.
  • the movable seal can move several millimeters per door and thus compensate for tolerances. In order to ensure that the seals close completely to one another, one magnet is also used on each door.
  • the spring return in the sealing system serves to ensure that the sealing system either on one door or on both doors (if both are opened at the same time) "retracts" in the original position and thus an undisturbed opening of the door is possible.
  • the heating inserted in the seal serves to avoid condensation at high humidity. In principle, however, it is also possible to operate the sealing system without heating and magnets.
  • the electrical supply of the heaters from the door to the housing can either be wired via the hinge or wireless using pin contacts. This makes it possible to use the sealing system with all types of hinges.
  • the doors can now be opened and closed independently of each other. Due to the low influence of the system on the interior of the refrigerator or refrigerator-freezer combination, the space is optimally used in comparison to a folding bridge. Furthermore, due to the dampened closing and opening of the door, the noise development can be significantly reduced compared to using a folding bridge.
