Definitions

• the present invention relates to a refrigerator with an interior divided into several compartments, in particular a fridge-freezer or a freezer, in which at least one of the compartments has a door hinged to an access opening that separates the compartment from the rest of the interior.
• a refrigerator is known from DE-8903459 U. With him the door of a freezer compartment is held in a closed position by a snap connection.
• the snap connection of this known refrigeration device comprises a flexibly resilient element in the form of a capsule, from which a ball protrudes, which can be pressed in against the force of a spring accommodated in the capsule, and an element which deforms the flexibly resilient element in the form of a projection on the freezer compartment door, which pushes the ball in when opening and closing the door.
• a recess In order to be able to mount the capsule on the inner container, a recess must be formed in the inner container, into which the capsule can be inserted and in which it finds a firm hold.
• the object of the present invention is to provide a refrigeration device with an interior divided into several compartments and at least one door attached to one of the compartments, which is inexpensive to manufacture and easy to assemble.
• the object is achieved by a refrigerator with the features of claim 1. Since the flexible, resilient element according to the invention is formed by a wall section of the housing or the door, a separate component for the flexible element can be dispensed with, and the number of parts when the Refrigerator required parts are reduced.
• the flexible, resilient element is a section of an inner container of the refrigeration device, and is preferably in one piece the inner container.
• a wall section can be made flexible in that a thermally insulating filling, with which the walls of the housing are filled, is left free on the flexible, flexible wall section.
• the flexible, resilient element is in a section of a wall of the door.
• the deforming element is preferably attached to the inner container as a separate component; this allows this element to be molded from a material that is more resistant to abrasion than the inner container itself.
• the deforming element is preferably designed in the form of a stopper which is inserted into a recess in the housing, in particular in the inner container of the housing.
• the flexibly resilient element is preferably a section of the wall of the door facing the deforming element. There is then preferably a cavity on a side of this wall section facing away from the deforming element, in which the flexibly flexible element can move back elastically when the door is opened and closed.
• a flexible, flexible element can easily be realized in a border area between a front and a rear shell, which are each part of the wall of the door.
• Opposing edge areas of the inner and outer shell can delimit a groove for receiving a sealing profile.
• the cavity is preferably part of such a groove.
• the outer wall comprises a handle piece which is formed separately from the door leaf, that is to say an area which a user can grip on in order to open or close the door
• the flexible element is also formed on the handle piece.
• wear of the flexibly flexible element necessitates a repair, it is sufficient to simply replace the handle, while the remaining parts of the door remain intact.
• fretting wear in that the handle is made of a more friction-resistant material than other outer parts of the door.
• the snap connection is preferably arranged on a side of the door facing away from the pivot axis of the door. Although it would also be conceivable to place the snap connection on a side flank of the door crossed by the pivot axis, two snap connections on opposite side flanks would then generally be required for secure locking.
• the flexible, resilient element does not necessarily have to touch the deforming element directly.
• a protective body in a contact area between flexibly resilient element and deforming element can be attached in order to minimize frictional locking on these elements.
• the flexible element can also be formed by a hinge of the door itself or can be arranged thereon.

• the two-temperature refrigerator 10 shown in a perspective front view in FIG. 1 comprises a heat-insulating body 12, on which an outer door 11 is hinged about a vertical axis.
• the interior of the body 12 is divided by a thermally insulating horizontal intermediate wall 14 into a normal cooling compartment 13 and a freezer compartment 15.
• a freezer door 16 is pivoted about a horizontal axis, which in the figure is open , horizontal position is shown and in the closed position closes the front opening of the freezer compartment 15 essentially airtight.
• the freezer compartment door 16 is composed of an outer shell 17 facing the outer door 11 and an inner shell 18 facing the interior of the freezer compartment 15, which touch in their edge regions and enclose an interior space which is essentially filled with thermally insulating foam material 19.
• a recessed grip 20 is molded in at the upper edge of the outer shell 17. It is closed at the top by an advanced web 21 of the outer shell 17 and a handle 22 which, like the shells 17, 18, is injection-molded in one piece from plastic.
• a horizontal leg 23 of the handle 22 is attached to the web 21, e.g. by latching or gluing.
• a recess 25 on the top of the horizontal leg 23 is part of a snap connection through which the door leaf 16 can be locked in the vertical position.
• a second part of the latching connection is formed by a projection 26 fastened to the inner container of the body 12.
• the projection is part of a plug 27 made of rigid, abrasion-resistant plastic material, one of which Base section engages positively and frictionally in a recess 28 which is formed on the upper wall of the inner container of the body 12.
• the projection 26 engages in the recess 25 on the horizontal leg 23 of the handle 22.
• a horizontal edge 29 protruding inward opposite the web 21 and the outer shell 17 supports the horizontal leg 23 below the recess 25.
• a narrow gap 33 extends between the horizontal edge 29 of the outer shell and an edge of the inner shell 18. This gap 33 also enables the horizontal edge 29 to yield slightly downwards when the projection 26 extends the edge portion 30 happens.
• the horizontal leg 23 is attached to the web 17 and the edge 29 of the outer shell 17 over a large area, e.g. by gluing or by a clamp on the outer tips of the web 21 and the edge 29. This allows a user to facilitate the release of the snap connection when opening the door, by not only horizontally forward on the vertical leg 24 of the handle 22 or pulls to the right in the figure, but at the same time pulls the vertical leg 24 upwards and thereby lowers the edge section 30.
• FIG. 4 shows a perspective view of the upper area of a door 16 according to an alternative embodiment of the invention.
• the upper area of the outer shell 17 with the recess 20, which is partially covered by the handle 22, is formed in the horizontal leg 23 of the handle 22 and an elongated slot 34 is formed, and between the slot 34 and the rear edge of the leg 23 is formed in a flat bead 35.
• the leg 23 is not supported below the bead 35.
• This and the slot 34 facilitate bending of the bead 35 in the longitudinal direction of the handle if the projection 26 slides over the bead 35 when the door is opened and closed.
• the slot 34 or the adjacent flank of the bead 35 have the function of a recess here, on which the projection 26 of the frame rests in the closed position of the door.
• the elastic deformation of the door leaf which is necessary for the change between open and closed positions, need not be limited to the flank of the door 16 facing the projection 26. A certain contribution to flexibility can also result from the elastic deformability of the shells
• FIG. 5 Another way of making the door resilient is shown in FIG. 5.
• a blind hole 37 is deep-drawn in a left side flank 36 of the door.
• a cylindrical pivot 39 is received in a form-fitting manner in an inner section 38 of the blind hole.
• the diameter of an adjoining outer section 40 of the blind hole gradually increases toward the side flank 36.
• a free end of the pivot pin 39 protruding from the blind hole 37 is provided in order to rotatably engage in a recess in a side wall of the inner container of the body 12.
• the opposite right lower corner of the door 16 is constructed in the same way.
• the upper edge area of this door 16 can e.g. be constructed as shown in Fig. 3, but in this embodiment, the edge portion 30 may be rigid.
• FIG. 6 illustrates a third embodiment of the refrigeration device according to the invention on the basis of a partial section, which shows an upper edge region of the freezer compartment door 16 and a section of the ceiling of the inner container 41 opposite this edge region.
• two inclined flanks of projections 42 and 43 formed on the top of the door 16 and the inner container 41 abut one another. Both projections 42, 43 are each formed in one piece with the outer wall of the freezer compartment door 16 and the inner container 41.
• the freezer compartment door 16 is completely filled with insulating foam material 19.
• the shell 44 keeps the space on the rear side of the projection 43 free of insulating foam and thus allows the projection 43 and surrounding wall regions of the inner container 41 to retract under the pressure of the projection 42 when the door 16 is opened and closed.
• FIG. 7 A further development of this embodiment is shown in FIG. 7.
• the door 16 is here identical to that shown in FIG. 6.
• the inner container 41 has a flat depression 46 opposite the protrusion 42 of the door 16, into which a buffer body 47 is inserted, which replaces the protrusion 43 from FIG. 6.
• An advantage of this modification is that the trough 46 is easier to produce when the inner container 41 is deep-drawn than the projection 43, which makes it difficult to remove the punch from the inner container after the deep-drawing.
• the buffer body 47 can be exchanged without difficulty if it is worn out by friction with the projection 42 of the door 16.
• the buffer body 47 can be rigid in itself and pass on the entire deformation forced when the door 16 is opened and closed to the inner container 41, but it can also consist of an elastic material that absorbs some of this deformation and thus relieves the inner container 41.
• the inner container 41 is completely flat in the area deposited with the shell 44, and a projection that cooperates with the projection 42 of the door 16 is on a large area on the inner container 41 opposite the Shell 44 adhered buffer body formed.
• FIG. 8 shows, as a fourth embodiment of the invention, a partial section through a freezer. Its interior is divided into several compartments 52 by horizontally arranged evaporators 51, each of which can be locked by a door 53. Since the individual compartments 52 do not have to be insulated from one another, the doors 53 have only a simple wall and no insulating filling. They are each hinged to the side walls of the inner container. Each door has a horizontal top flank 54 from which a projection 55 projects upward. The projection 55 of the top door 53 acts with a downward projection 56 on the inner container together.
• the projection 56 of the inner container can be rigid and can have a deforming effect on the projection 55 of the door, as in the case of those with reference to FIGS.
• the projection 55 of the door can be rigid and deform the projection 56 of the inner container, as in the embodiments of Figs. 6 and 7.
• the projections 55, 56 can also be flexibly deformable at the same time and have a deforming effect on the respective other projection.
• the evaporators 51 each carry on their door-side edge a plastic rail 57, which has a projection on its underside analogous to the projection 56 of the inner container and forms a snap connection together with the projection 55 of the door 53 below it.
