DETAILED DESCRIPTION OF THE INVENTION

(9) Referring now in detail to the figures of the drawings, in which identical elements or those of identical function are shown with the same reference characters, and first, particularly, to FIG. 1 thereof, there is seen a household appliance 1, in the form of a household refrigeration appliance, configured to store and preserve food. In the exemplary embodiment the household appliance 1 is a combined refrigerator/freezer appliance. The household appliance 1 has a body 2, in which a number of separate receiving chambers for food are configured. A first receiving chamber 3 is provided in this case and configured in the present exemplary embodiment as a refrigeration compartment. The household appliance 1 also includes a keep-fresh compartment 4 configured below the refrigeration compartment in the height direction (Z direction) and representing a sub-volume of the refrigeration chamber 3, in which an air humidity and/or temperature can be set which is different from the remaining sub-volume of the receiving chamber 3 above it.

(10) Provision is made in the exemplary embodiment for the receiving chamber 3 to be able to be closed by a number of separate doors disposed at the front. The keep-fresh compartment 4 in this case can be closed by a door 5, which is a front wall of a drawer that can be moved linearly in the depth direction (Y direction). The remaining sub-volume of the receiving chamber 3 can be closed by two further separate doors 6 and 7, which can be pivoted separately and independently of one another about vertical axes and therefore axes oriented in the height direction. This configuration allows the remaining sub-volume of the receiving chamber 3, which is not formed by the keep-fresh compartment 4, to be opened and closed independently of the keep-fresh compartment 4, by pivoting the doors 6 and/or 7 correspondingly. The keep-fresh compartment 4 in turn can be opened independently, by opening the door 5 and thus pulling out the drawer.

(11) The household appliance 1 also includes two further separate receiving chambers 8 and 9, which are freezer compartments.

(12) The two freezer compartments can also be closed in turn by separate doors 10 and 11. The doors 10 and 11 are also front walls of drawers that can be moved linearly in the depth direction in the exemplary embodiment shown herein. It is therefore shown by way of example that the lower freezer compartment can be closed by the front wall of a drawer 12 which is configured as the door 11, with the drawer 12 being shown in the pulled-out state in this case.

(13) The receiving chambers 3, 8 and 9 are delimited by an inner container, which is made in particular of plastic, the inner container having side walls or wall elements 13 and 14 oriented in the height direction as shown in the view in FIG. 2, which shows a sub-region of the household appliance 1 in the region of the lower freezer compartment. In the view in FIG. 2 the drawer 12 is pulled out, so it is possible to look into the interior of the freezer compartment formed by the receiving chamber 9. It can be seen that a pull-out apparatus 15, which is telescopic, is disposed on an inner face 14a of the wall element 14, which at least partially delimits the receiving chamber in the form of the side wall. A corresponding pull-out apparatus, which is not shown in FIG. 2, is disposed on the opposing wall element 13, which also at least partially delimits the receiving chamber in the form of the side wall. The drawer 12 is disposed on these pull-out apparatuses 15, which are oriented in the depth direction, and can be moved by using the rail-type pull-out apparatuses 15.

(14) As is also shown in FIG. 1, the drawer 12 has a container 16, which is configured to receive food, in addition to the front wall, which forms the door 11.

(15) A built-in part 20, in particular in the form of the pull-out apparatus 15, is fastened by a separate holding part (not shown in FIG. 2) made of metal to the wall element 14. This part is therefore also provided in the pull-out apparatus, which is fastened to the wall element 13. It can also be seen in FIG. 2 that a rail-type holding part 17 is disposed on an outer face 13b, opposite an inner face 13a, of the wall element 13. This outer face 13b faces away from the receiving chamber 9 and faces an outer wall 18 (FIG. 1), which is a further part of the body 2. A space, into which thermally insulating material, in particular insulating foam, is introduced, is provided between the outer wall 18 and the inner container 19, as shown in FIG. 2.

(16) FIGS. 3 and 4 show a partial detail of the inner container 19. They show an alignment contour 21, which is configured as a single piece with the inner container 19 and therefore also with the wall element 14. The alignment contour 21 is formed by a projection 22 by thermoforming when the inner container 19 is produced. The alignment contour 21 therefore substantially has a constant wall thickness over the entire projection 22. The wall thickness corresponds substantially to the wall thickness of the wall element 14 away from the alignment contour 21. The projection 22 extends from the receiving chamber 9 in the width direction X. In particular, the projection 22 is configured on the face 14b of the wall element 14 facing away from the receiving chamber 9. A recess 23 configured to complement the shape and size of the projection 22 is configured on the inner face 14a of the wall element 14 facing the receiving chamber 9.

(17) The projection 22 is configured to be elongated. In particular, a longitudinal extension 24 is greater than a widthwise extension 25 and greater than a height extension 26. The projection 22 is positioned in such a way that its longitudinal extension 24 extends parallel to the depth direction Y.

(18) The projection 22 has a rib-like segment 27, which has a longitudinal extension 28 that is approximately 75% of the longitudinal extension 24 of the entire projection 22. Enlargement segments 30 are formed on end segments 29 of the rib-like segment 27. The enlargement segments 30 extend beyond the rib-like segment 27 in both the width direction X and the height direction Z. Therefore, the segments of the recess 23 formed by the enlargement segments 30 are deeper and wider than the segment of the recess 23 formed by the rib-like segment 27. In particular both enlargement segments 30 have a greater height extension (corresponding to the height extension 26 of the entire projection) than the height extension 32 of the rib-like segment 27.

(19) The alignment contour 21 has two apertures 31 configured within the recess 23. The apertures 31 are both disposed completely within the rib-like segment 27.

(20) The recess 23 has bearing surfaces 33, 34. The bearing surfaces 33 are formed by boundary walls of the segment of the recess 23 formed by the complementary shape of the enlargement segment 30. The bearing surface 34 is formed by a side boundary wall 35 of the segment of the recess 33 formed by the rib-like segment 27. The side boundary wall 35 and therefore the bearing surface 34 is configured to be substantially horizontal. The size of the bearing surface 34 is greater than the sum of the surfaces of the bearing surfaces 33. The projection 22 has bearing surfaces 36, 37.

(21) The wall element 14 also has three apertures 38a, 38b, 38c. The alignment contour 21 is disposed between two adjacent apertures 38b, 38c in the depth direction Y. In particular, the alignment contour 21 is configured so that it does not overlap with the apertures 38a, 38b, 38c. The apertures 38a, 38b, 38c and the alignment contour 21 are disposed substantially in one height plane in the height direction Z.

(22) The apertures 38a, 38b, 38c are also disposed in the wall element 14, in other words in the side wall. The wall element 14 transitions as a single piece into a further wall element 39, which forms a base of the receiving chamber 9.

(23) FIG. 5 shows a holding part 40 disposed on the wall element 14. The holding part 40, which is a single piece made of metal, has a coupling region 42 disposed non-centrally relative to its longitudinal extension 41. The coupling segment 42 only extends over a sub-segment 65 of the longitudinal extension 42.

(24) The coupling segment 42 includes a bridge element 43 and two apertures 45 disposed on its end segments 44. Provided on the bridge element 43 is a support surface 46 which, when the holding part 40 is in the mounted state, is in contact with the bearing surface 37, to transfer weight forces acting on the holding part 40. The bridge element 43 also includes screw holes 47, which are configured in a cylindrical indentation 48.

(25) The holding part 40 also includes three fastening segments 49, which are formed substantially by projections 50. The projections 50 extend counter to the width direction X, in other words in the direction of the receiving chamber 9 (see also FIG. 7). The projections 50 are configured with rotational symmetry and each have a centrally disposed screw hole 51, which is configured in a cylindrical indentation 52.

(26) The holding part 40 also has two ribs 53, which are provided over the entire longitudinal extension 41 and project from a base plate 54 in the width direction X.

(27) FIG. 6 shows the holding part 40 mounted on the inner container 19, in particular on the wall element 14. It also shows the bridge element 43 engaging in a form-locking manner over the rib-like segment 27. The apertures 45 frame the enlargement segment 30.

(28) Bonding devices 55, 56 are also shown diagrammatically. The (partially shown) bonding device 55 is hot glue, which can be applied over all of the edge segments of the holding part 40. The (partially shown) bonding device 56 is adhesive tape, which can be applied over the entire surface of the holding part 40 facing away from the wall element 14.

(29) As is shown in FIG. 7, the fastening segments 49 engage in the apertures 38a, 38b, 38c. Surfaces 57 of the fastening segments 49 do not project into the receiving chamber 9 in this case. Instead, the surfaces 57 are substantially flush with a surface of the wall element 14 framing the apertures 38a, 38b, 38c.

(30) A fixing element 58 (see also FIG. 8) is disposed in the recess 23. The fixing element 58 is connected to the holding part 40 by using two screws 59, which penetrate the apertures 31. The fixing element 58 has two through holes 60 for this purpose.

(31) A surface 61 of the fixing element 58, which is manufactured as a single-piece injection molded plastic part, does not project into the receiving chamber 9 in this case. Instead, the surface 61 is set back in the width direction X relative to the receiving chamber 9.

(32) The fixing element 58 includes a rib-like center piece 62 and two dish-type extension pieces 64 formed on its end segments 63. In the mounted state the fixing element 58 fills the recess 23 substantially completely. Provided on the center piece 62 is a support surface 66, by using which the fixing element 58 can be supported on the bearing surface 34.

(33) The following is a summary list of reference numerals and the corresponding structure used in the above description of the invention.
