Description

Door leaf, method for producing a door leaf and refrigeration device with a door leaf

The invention relates to a door leaf for a refrigeration device, a refrigeration device and a method for producing a door leaf of a refrigeration device.

DE 20 2007 007 321 U1 discloses a household refrigerating appliance whose door leaf comprises an outer wall, an inner wall and an upper and a lower closing element which delimit an inner cavity which is filled with a heat-insulating material. The outer wall comprises a front panel, two side flanks adjacent to the front panel, and edge bars engaging behind the front panel. From

Plastic finished terminating elements each comprise a flat base plate and a second plate integrally connected thereto and parallel thereto, which together define a forwardly open groove into which ribs protrude to clamp therein an angled web of the outer wall. The door leaf further comprises mutually symmetrical locking body, which are provided to be inverted in each case after assembly of the relevant end element with the outer wall via bearing bushes of the closure element.

The object of the invention is an improved door leaf of a refrigeration device

which in particular can be made easier.

Under a refrigeration device is in particular a household refrigeration appliance understood, ie a refrigeration appliance for household management in households or possibly in the

Catering area is used, and in particular serves to store food and / or drinks in household quantities at certain temperatures, such as a refrigerator, a freezer, a fridge-freezer or a wine storage cabinet.

The object of the invention is achieved by a door leaf for a refrigeration device, comprising an outer wall, an inner wall, two side walls, an upper and a lower

Door closure strip defining a cavity filled with a heat-insulating material, wherein the outer wall in the upper and / or lower region a front Has folded over and at least one of the door closure strips has a horizontally extending groove which engages in the front fold, and the at least one door seal strips has at least one integrally formed latching means which is locked to one of the side walls. Thus, the relevant door closure strip is connected both by means of the groove of the door closing strip and the front edge of the outer wall formed plug connection and the locking means realized by means of the locking means with at least one of the side walls. As a result, the door leaf according to the invention can be produced relatively simply by, for example, latching the door leaf

Door closure strip with the side wall by means of the locking means due to a from above in a forward pivoting movement of the door closing strip is realized. The invention thus optionally provides a one-piece door closure strip for a so-called flat door.

In particular, the door leaf according to the invention can be produced as follows: obliquely placing the door closing strip coming from above onto the side walls,

- sliding the door closing strip to the front, whereby the door closing strip lowers relative to the outer wall and the side walls and the door closing strip engages with its groove in the front edge, and

- Push down the door closing strip in its rear area to the

Door closure strip to lock by means of the locking means with at least one of the side walls. Preferably, the relevant door closure strip on both sides of a locking means, which are each locked with their side walls.

Another aspect of the invention relates to a refrigeration device, comprising a body with a coolable interior and an opening and closing of the interior provided, hinged to the body according to the invention door leaf. The refrigeration device is designed in particular as a household refrigeration appliance, for example as a household refrigerator or as a freezer-refrigeration combination. In order to obtain the best possible attachment of the door closing strip with the outer wall by means of the groove and the front fold, it may be provided according to an embodiment of the door panel according to the invention, that the front edge of the outer wall and / or that the groove of the door closure strip over the entire Width of the door leaf extends.

For a pleasing appearance of the door panel according to the invention, it may be provided that the lower and / or upper door closure strip rests on the front edge, in particular without overhanging the outer wall. According to one embodiment of the door panel according to the invention, the lower and / or upper door closure strip in particular integrally formed lateral ribs. These may preferably extend over the entire depth of the door leaf. When assembling the door panel according to the invention it is then possible that e.g. the

Door closing strip coming from above is placed on the side walls, and then the door closing strip along the contours of the lateral ribs is pushed forward, whereby the door closing strip lowers relative to the outer wall and the side walls and the door closing strip engages with its groove in the front edge. The locking means of the door closing strip can in particular be designed such that the lateral rib comprises this.

The side walls may have lateral folds in the region of the upper and / or lower door closure strip. On these, the lower and / or upper

Door seal strip rest.

The lateral folds are then relatively advantageous if, as is provided according to an embodiment of the door leaf according to the invention, the locking means as a particular integrally formed in the rear region of the door seal strip

Detent hook is formed. The latching hook can then be locked in a relatively simple manner with the lateral fold or lock when pressing down the door seal strip with the lateral fold. The side walls may comprise as rear vertical edges in particular a semicircular or teardrop-shaped bending contour. To the bending contour can connect a vertically, in particular over the entire height of the door panel extending section. This section can be provided, for example, that the inner wall rests on this and, if appropriate, the inner wall is fastened to this section.

The lateral fold can only cover part of the depth of the door leaf

in particular extend to just before the bending contour. The lower and / or upper

Door closure strip may also have a particular integrally molded rear rib. This can e.g. be provided that rests on this, the inner wall and optionally the inner wall is attached to the rear rib. The rear rib may extend between the two vertical sections. Preferably, the outwardly directed side of the rear rib is flush with the outwardly facing sides of the portions of the inner skins. In order to produce the door leaf as inexpensively as possible, the outer wall and the two side walls can be made in one piece from a single piece of sheet metal.

An embodiment of the invention is illustrated by way of example in the accompanying schematic drawings. Show it:

Figures 2, 3 assembly steps to illustrate the assembly of the door panel and

Figures 4, 5 partial views of the door panel in the assembled state.

FIG. 1 shows a household refrigerating appliance 1 as an example of a refrigerating appliance. The

Domestic refrigeration appliance 1 has a body 2 with an inner container 3, which is divided in the present embodiment into a freezer compartment 4 arranged above and a cooling space 5 arranged below the freezer compartment 4. The freezer compartment 4 is used, for example, for freezing frozen food at eg about minus 18 degrees Celsius. The household refrigerator 1 further comprises a non-illustrated, the skilled person in principle, however, known cooling device for cooling the freezer compartment 4 and the refrigerator 5, which is controlled by a control device, not shown, so that the refrigerator 5 and the freezer compartment 4 at least approximately in advance have set target temperature. The refrigeration device comprises, for example, one or more refrigeration circuits, which have, for example, one or more evaporators, condenser, etc.

The household refrigerating appliance 1 has two door leaves 6, 7 hinged to the body 2 for closing the freezer compartment 4 or the refrigerator compartment 5. When the door leaves 6, 7 open the freezer compartment 4 and the refrigerator 5 are accessible. At the direction of the refrigerator compartment 5 side facing the closing of the refrigerator compartment 5 provided door leaf 7, ie on the inner wall 1 1 of the door panel 7 a plurality of door racks 8 are arranged in the case of the present embodiment.

In the case of the present embodiment, a designed as a support grid 9 shelf is arranged in the freezer 4, can be stored on the frozen food, and in the refrigerator 5 a plurality of shelves 10 are arranged one above the other, on which refrigerated goods can be stored.

Figures 2 and 3 illustrate the assembly of the door panel 7. The door panel 6 may be similar to the door panel 7 constructed and mounted accordingly. FIGS. 4 and 5 show sections through the completely assembled door leaf 7.

In the case of the present embodiment, the door panel 7 comprises the inner wall 1 1, which is made, for example, of plastic and preferably by injection molding, and an outer wall 12. Between the inner wall 1 1 and the outer wall 12 is a heat-insulating material, e.g. an insulating foam arranged.

The outer wall 12 is made in the case of the present embodiment of metal, in particular a sheet 17. The sheet 17 is on the sides of the

The outer wall 12 is bent backwards and also forms side walls 13 of the door leaf 7. In the upper part of the outer wall 12 and the side walls 13, the sheet 17 is bent and forms the upper edge of the outer wall 12, a front edge 14 and the upper edges of the two side walls 13 lateral folds 15th The front The folded edge 14 and the lateral folds 15 merge into each other in upper corners 16. In the lower region of the outer wall 12 and the side walls 13, the sheet 17 is bent according to the upper region and there also forms lateral

Folds and a front fold. In the case of the present embodiment, the sheet 17 in the rear region of the side walls 13 arcuate, in particular semicircular or tear-shaped bent to form on both sides in each case a vertical or from top to bottom extending bending contour 18. The bending contours 18 then the sheet 17 is further bent and includes vertically extending portions 19, the surfaces of which extend parallel to the outer wall 12. The sections 19 are provided to be connected to the inner wall 1 1. The bending contours 18 and the sections 19 extend in particular over the entire height h of the door leaf 7.

The door leaf 7 also has an upper door closure strip 20 and a lower door closure strip formed in accordance with the upper door closure strip 20. The

Door closure strips 20 are each in one piece or in one piece, in particular einstoff preferably produced by injection molding and form boundaries of the door panel 7 upwards or downwards. In the assembled state of the door leaf 7, the door closure strips 20 do not grip over the sheet 17, but lie flat on the folded edges 14, 15. The door closure strips 20 are also fastened to the plate 17 by means of a plug connection and a latching connection.

In the case of the present embodiment, the door closure strips 20 each have a horizontally extending groove 21 in the front region. The groove 21 extends in particular substantially over the entire width b of the door leaf 7 and the door seal strip 20. The groove 21 of the door seal strip 20 is executed in depth and height such that the door seal strip 20 engages with the groove 21 in the front folded edge 14.

In the case of the present exemplary embodiment, the door closure strips 20 also each have two latching hooks 22 integrally or integrally molded on the respective door closure strip 20. The latching hooks 22 are each in the rear area and formed laterally on the door closure strip 20 so that they each have a latching hook 22 on each of its two side walls 13 facing sides. in the

latched state, the latching hooks 22 are latched to the lateral folds 15, as shown in FIG. 5 is illustrated. In the case of the present exemplary embodiment, the door closure strips 2 have ribs 23 which are formed laterally in one piece or one-piece, and which are in particular in the

Essentially over the entire depth t of the door closure strips 20 and the door leaf 7 extend. The snap hooks 22 are, for example, as in the present

Embodiment is the case, part of the ribs 23rd

In the case of the present embodiment, the lateral folded edge 15 of the sheet 17 extends only over a part of the depth t of the door leaf 7, in particular until shortly before the bending contour 18. The door closure strips 20 are again designed in the region of the bending contours 18 so that they are in shape the bending contours 18 and the missing lateral folds 15 are adapted.

Furthermore, the door closure strips 20 have in their rear regions in each case an integrally formed or integrally molded rear rib 24 which extends over only a part of the width b of the door leaf 7. The rear rib 24 lacks in the region of the vertically extending portion 19 of the sheet 17 and extends in particular with its outwardly directed surface 25 flush with the outwardly directed surface 26 of the vertically extending portion 19 of the sheet 17. In the region of the vertically extending portion 19 of Sheet 17 thus form the rear rib 24 and the lateral ribs 23 each have a gap 27 into which the bending contour 18 of the sheet 17 enters the gap 27 during assembly of the door leaf 7.

The rear rib 24 and the vertically extending portion 19 of the sheet 17 are slightly offset rearwardly with respect to the rear edge of the door trim strips 20 and are particularly intended to be in contact with the inwardly facing side of the inner wall 11.

In the case of the present embodiment, the door closure strips 20 are fastened to the metal sheet 17 as follows: The relevant door closure strip 20 is placed obliquely coming from above on the sheet 17, so that the front corners 28 of the door closure strip 20 rest on the lateral fold 15 of the sheet 17 and the lateral ribs 23, in which in the case of the present embodiment each one of the latching hooks 22nd is introduced, rests on the rear bending contour 18 of the sheet 17, as shown in FIG. 2.

There is a gap between the front edge of the door closure strip 20 and the front folded edge 14. In addition, the front edge of the door closure strip 20 and the front edge 14 run parallel. The door closure strip 20 is now pushed along the contours of the lateral ribs 23 to the front. In this case, the door closure strip 20 lowers relative to the sheet 17, as shown in FIG. 3 is illustrated. As soon as the door closure strip 20 rests against the front, in that the groove 21 of the door closure strip 20 engages in the front edge 14, the door closure strip 20 can be pressed downwards at the rear, as shown in FIG. 4. In this case, the latching hooks 22 lock each with their lateral folds 15 on the left and right sides in their final position, as shown in FIG. 5. Thus, the door closure strips 20 are fixed in all directions: The latching hooks 22 hold the

Door end strips 20 down while the rear edge of the side rib 23 holds the position forward.

Connecting the cavity formed by the door closure strips 20 and the sheet 17 can be filled with an insulating foam and then the inner wall 1 1 are attached to the plate 17 and the door seal strips 20 to completely assemble the door panel 7.
