Abstract
A domestic appliance including a door that has an inner wall and an outer wall, wherein each of the inner wall and the outer wall has longitudinal edges and transverse edges, and wherein the inner wall is connected to the outer wall along the longitudinal edges. A closing element is connected to a respective transverse edge of the inner wall and/or the outer wall and has a groove that is open towards an exterior side of the door. A ledge, which is supported by the outer wall and arranged along at least one of the transverse edges and which is angled towards the inner wall, is engaged in the groove of the closing element.
Description
- The present invention relates to a domestic appliance, especially a refrigeration appliance, comprising an outer wall and an inner wall, which are connected to one another along longitudinal edges, and at least one closing element, which is connected to respective transverse edges of the outer wall and the inner wall. Such a door is known for example from DE 103 02 797 A1 and DE 102 59 749 A1.
- A door of such structure can be produced simply in differing heights, as the outer and inner wall can be cut and formed from the same flat material in the length required for the desired structural height of the door and an identical model of closing element can be incorporated in doors of differing height.
- One disadvantage of this known door is however that the closing element has to project slightly over the outer wall in order to be able to accommodate a transverse edge of the outer wall in a groove. The closing element is therefore clearly visible on the finished door and the surface of the door forms a small step, where dirt can collect, where the outer wall enters the groove of the closing element.
- It is therefore desirable both from an aesthetic point of view and also with a view to easy cleaning, to develop the door described in the introduction so that the projection of the closing element over the outer surface of the door is avoided or the closing element is less evident.
- According to the invention the object is achieved in that with a domestic appliance of the type mentioned in the introduction the outer wall of the door supports a ledge angled toward the inner wall along at least one of the transverse edges and the closing element has a groove open toward the exterior of the door, the ledge engaging in said groove.
- While therefore with the conventional doors described above an edge region of the outer wall engaging in the groove of the closing element is flush with the remainder of the outer wall, and a groove accommodating the edge region necessarily has to have a side wall, which projects over the outer wall, according to the invention the fact that the angled ledge forms the edge region engaging in the groove makes it possible for the closing element to be moved back behind the front face, with the result that the closing element is largely hidden from the eyes of the observer and front face can be achieved, which is free from steps that may accumulate dirt.
- In order on the one hand to be able to clamp the ledge firmly in the groove and on the other hand also to prevent too large a force being required to insert the ledge into the groove, the groove is preferably wider that the ledge engaging therein and the ledge is clamped on ribs projecting from a side wall of the groove.
- The outer wall preferably forms a front panel and two side edges of the door adjoining the front panel in the known manner.
- If the outer wall also comprises two peripheral ledges engaging behind the front panel from the side edges, the length of a wall of the closing element supporting the front panel is preferably shorter than the distance between the peripheral ledges, in order not to impede the insertion of the angled ledge into the groove on the closing element.
- The closing element is also preferably provided with two tabs on the outside of the side edges to fix the outer wall.
- A stiffening element is expediently fitted over a door bearing bush formed on the closing element. The stiffening element can help to fix the outer wall in a different manner. Thus on the one hand the side edge of the outer wall can be fixed between the stiffening element and the tab. On the other hand the stiffening element can also form a stop, against which one of the side edges respectively rests.
- To fix the outer wall it is particularly preferable for said outer wall to form a hollow rib in each instance between the side edge and the peripheral ledge and for the stiffening element to have a protrusion engaging in the hollow space of the rib.
- To simplify the assembly of the door, the stiffening element is preferably latched to the closing element.
- The door bearing bush can serve as an injection opening for injecting insulating material into a hollow inner space in the door.
- Alternatively a vent valve can be accommodated in the door bearing bush to vent a hollow inner space in the door.
- In practice a number of door bearing bushes are generally present on a door, so that one can expediently serve as an injection opening and the others are provided with a vent valve.
- Further features and advantages of the invention will emerge from the following description of exemplary embodiments with reference to the accompanying figures, in which:
-
FIG. 1 shows a perspective view of an inventive door; -
FIG. 2 shows a perspective view of the outer wall of the door; -

FIG. 5 shows a perspective view of a stiffening element; -
FIG. 6 shows a horizontal section through the door, showing the stiffening element from above; -
FIG. 7 shows a section through the closing element in a sectional plane parallel to the one inFIG. 4 ; -
FIG. 8 shows a perspective view from the front of a closing element according to a second embodiment; -
FIG. 9 shows a perspective view from behind of the closing element fromFIG. 8 ; -
FIG. 10 shows a fragmented perspective view of the closing element fromFIG. 8 , an outer wall mounted thereon and a stiffening element to be mounted thereon, and -
FIG. 11 shows a partial section through the closing element, the outer wall and the stiffening element fromFIG. 10 in the assembled state. -
FIG. 1 shows a perspective view of an inventive door, which can serve as the door of a refrigerator or freezer or as one of a number of doors of a combination refrigeration appliance. In the known manner the door comprises anouter wall 1, which is formed as a single piece from sheet metal that has been cut to size, anupper closing element 2, alower closing element 3 and an inner wall that is not visible in the view inFIG. 1 . - The
outer wall 1 is shown in a perspective view inFIG. 2 , essentially showing the inner face of theouter wall 1, which is concealed when the door is mounted. The outer wall is made up of a slightlycurved front panel 4, twoside edges 5, each connected to the sides of thefront panel 4, and twoperipheral ledges 6 engaging behind thefront panel 4 from theside edges 5. Theperipheral ledges 6 serve respectively to secure the rear wall (not shown here). This is cut to size in the known manner, which is therefore not described in detail here, from flat plastic material and formed by deep drawing. - The
outer wall 1 forms ahollow rib 7 in each instance between theside edges 5 and theperipheral ledges 6. - A
ledge 8 is angled in a horizontal direction on the upper and lower edges of theouter wall 1 respectively. In each instance the width of theledge 8 is greater in acenter section 9 that at its twoends 10. -
FIG. 3 shows theupper closing element 2 of the door in the perspective fromFIG. 1 .FIG. 4 is a section through theupper closing element 2 along a plane identified as IV-IV inFIG. 3 . Theclosing element 2, which is injection molded from plastic, has aflat base plate 11 and asecond plate 12, which is joined together with this as a single piece and parallel to it, together limiting agroove 13 that is open to the front. Thesecond plate 12 holds a number ofribs 14 that engage in thegroove 13 and extend essentially in the direction of the depth of thegroove 13. Thesecond plate 12 projects over afront edge 15 of thebase plate 11. In a center region of the second plate 12 awall 16 is formed on its front edge, extending vertically downward. - When the door is fully mounted, the
groove 13 holds the upper of the twoledges 8 of theouter wall 1, theledge 8 being clamped between theribs 14 and thebase plate 11. When theledge 8 is inserted correctly into thegroove 13, the interior of thefront panel 4 is supported on thewall 16. As thewall 16 projects over thefront edge 15 of thebase plate 11, thefront panel 4 resting on thewall 16 does the same, thereby resulting in a door front face that is free from projections or steps and is easy to clean. - Two
angled tabs 17, projecting at the longitudinal ends of theclosing element 2, are provided, to rest on the outside of theside edges 6 and fix them in position in the assembled state as shown inFIG. 1 . - A vertically
oriented groove 19 extending along arear edge 18 of thebase plate 11 is provided, to hold and fix an upper edge of the inner wall. - Two
openings 20 of the base plate shown inFIG. 3 belong to bearingbushes 21, which are provided to hold a fixed trunnion (not shown) on a housing supporting the door in a rotatable manner. Thebearing bushes 21 are present in duplicate in a mirror-symmetrical arrangement in the known manner on each closing element, to allow the door to be mounted optionally on the left or right of the housing. -
FIG. 5 shows a perspective view of one of two mirror-symmetricalstiffening elements 22, which are provided to be fitted over thebearing bushes 21 of the closing element after theclosing element 2 has been joined to theouter wall 1 but before the assembly of the inner wall. Thestiffening element 22 has abase 23, the shape of which resembles a box that is open on one side, with a roughlysquare bottom plate 24 andside walls 25 to 28 connected to the edges of thebottom plate 24. In the assembled state thebottom plate 24 touches thebase plate 11 of theclosing element 2, thefront side wall 25 lies very close to thefront panel 4 as an extension of thewall 16 from inside, with acutout 29 at the foot of theside wall 25 holding thesecond plate 12 of theclosing element 2. Theouter side wall 26 rests on the inside of one of theside edges 5 and part of theside wall 27 touches one of theperipheral ledges 6. A rib-shaped protrusion 30 between theside walls hollow ribs 7 of theouter wall 1. Asleeve 31 of thestiffening element 22 encloses thebearing bush 21 in an essentially play-free manner.Ribs 32 that are oriented radially in relation to thesleeve 31 connect saidsleeve 31 to theside walls - Attaching the
stiffening element 22 on the one hand strengthens thebearing bush 21 so that a loadable door suspension can be achieved even with a relatively small wall thickness of theclosing element 2 but the particular benefit of thestiffening element 22 is the form-fit fixing of thefront panel 4. Because thestiffening element 22 engages with a form fit between thefront panel 4 and theperipheral ledges 6, it prevents thefront panel 4 moving forward when the hollow space formed by theouter wall 1, inner wall andclosing elements groove 13. - The
lower closing element 3 can be embodied as a mirror image of theupper closing element 2, as shown inFIG. 1 . One of the four bearingbushes 21 of theclosing elements bushes 21, which are at the corners of the interior furthest from the injection point, are then each expediently provided with a vent valve at their tip, to allow air but not foam to escape from the hollow space. -
FIG. 6 shows a horizontal section through a part of the door, with one of thestiffening elements 22 visible from above. It shows thesleeve 31, theribs 32 extending from it, thewalls 25 to 28 and the course of theouter wall 1 close to thewalls protrusion 30. In this embodiment, unlike the diagram inFIG. 3 , thetab 17 is extended to the rear around thehollow rib 7 and becomes arib 33, which forms an outer limit of thegroove 19 holding the inner wall, shown here as 34, of the door. -
FIG. 7 shows a section through theclosing element 2 and thestiffening element 22 mounted thereon in a plane parallel to the plane inFIG. 4 . In this plane a cutout 36 is formed in avertical wall 35 of theclosing element 2 connecting thebase plate 11 to thesecond plate 12, in which cutout 36 a latchingprotrusion 37 formed on thestiffening element 22 at the level of thecutout 29 engages. The latchingprotrusion 37 connects the stiffeningelement 22 to theclosing element 2 in a non-detachable manner once it is mounted on it. -
FIG. 8 shows a second embodiment of the closing element marked 2′, in a perspective corresponding to the one inFIG. 3 ;FIG. 9 shows the rear face of theclosing element 2′ in a perspective corresponding to the one inFIG. 2 . Corresponding parts of thisclosing element 2′ and theclosing element 2 described above are shown with the same reference characters. As with the closing element 2 abase plate 11 and asecond plate 12 limit agroove 13 that is open to the front and into whichribs 14 protrude, in order to clamp an angled awayledge 8 of theouter wall 1 therein. - A vertical
rear wall 38 is formed on thebase plate 11.Recesses 39 that are open to the rear and upward are formed in therear wall 38 and thebase plate 11, to hold an arm (not shown) that projects from the body of the refrigeration appliance and has at its end a bearing pin engaging in anopening 20 on the bottom of therecess 39, thereby concealing the arm from the view of an observer standing in front of the appliance. As with theclosing element 2, theopening 20 belongs to a bearingbush 21 protruding into the interior of the door. -
FIG. 10 shows a perspective view from below of a part of theclosing element 2′ with one of therecesses 39 and the bearingbushes 21 and a part of theouter wall 1 secured to theclosing element 2′ respectively. As described with reference to theclosing element 2, theouter wall 1 is anchored to theclosing element 2′, in that the ledge 8 (covered inFIG. 10 ) of theouter wall 1 engages in thegroove 13 of theclosing element 2′. Unlike theclosing element 2, here theperipheral ledge 6 of theouter wall 1 engages behind awall 45 of theclosing element 2′, which limits thegroove 19 holding the inner wall 34 (not shown), over a short distance. It is therefore not possible to join theclosing element 2′ and theouter wall 1 by simply pushing the two horizontally toward each other, thereby inserting theledge 8 into thegroove 13; instead, when theledge 8 is inserted into therib 13, theclosing element 2′ must be held at something of an angle, so that theperipheral ledge 6 can pass thewall 45 and only after passing saidwall 45 is theclosing element 2′ swiveled about a horizontal axis 40 (seeFIG. 8 ) so that one end of theperipheral ledge 6 comes to rest on thewall 45, as shown inFIG. 10 . This allows a first, tentative anchoring of theouter wall 1 to theclosing element 2′ to be achieved. - A final anchoring is achieved in that a
stiffening element 22′ shown separated from theouter wall 1 and theclosing element 2′ inFIG. 10 is pushed onto the bearingbush 21 of theclosing element 2′. The structure of the stiffeningelement 22′ is largely similar to that of the stiffeningelement 22 fromFIG. 5 , with the difference that in the case of the stiffeningelement 22 twotongues base 23, in order to engage respectively in a gap between the walls of therecess 39 and theside edge 5 or thefront panel 4 of theouter wall 1 in the assembled state. -
FIG. 11 shows a section through thetongue 42 engaging in agap 43 between awall 44 limiting thecutout 39 and thewall 16 supporting thefront panel 4. A latchingprotrusion 37, which engages in a cutout in thewall 16, causes thestiffening element 22′ to be connected in a non-detachable manner to theclosing element 2′.
