Definitions

• the present invention relates to a household appliance, in particular a refrigerator, according to the preamble of claim 1.
• the invention has for its object to provide a household appliance, in which the aforementioned problem is resolved and no aesthetic impression disturbing dents or the like deformations on the outer wall are present. This object is achieved with a household appliance according to claim 1.
• Advantageous developments of the invention are the subject of the dependent claims.
• the head of the fastener acts on the second, inner portion of the first outer wall but does not act on the first, outer portion thereof
• the head engages in tightening the fastener - e.g. a screw or a rivet - only in abutment with the second section, while it does not attack on the first section of the first outer wall. Therefore, since the head exerts no force on the first portion, no disturbing dent or the like is generated, and the visible portion of the outer wall remains undamaged.
• At least two of the through holes are at least approximately aligned with each other. This results in a particularly simple production of these holes.
• the diameter of the through hole in the first portion is larger than the diameter of the head and the diameter of the through hole in the second portion is smaller than the diameter of the head, thus the head can be tightened by tightening the fastener through the through hole in pass first portion of the first outer wall of a deformable material and thus comes into abutment with the second portion thereof.
• a spacer such as a washer or bush could be provided, which is penetrated by the fastener, on the one hand passes through the first portion, but does not act on it, and on the other hand engages the second portion, so that the head of the fastener below Interposition of the spacer can only exert a force on the second section.
• the fastening means preferably does not directly engage with a wall part to be connected to the first outer wall, but rather with the backing part attached thereto.
• the fastening means can also act on the backing part, which is connected to the wall part, for example by welding or gluing, in one piece or is even a part of this wall part.
• the first and second outer walls are preferably the side walls of the device.
• the present invention can be used particularly advantageously if the wall part as the front part of a household appliance such as a cooker,
• Dishwasher, tumble dryer or a washing machine but in particular as a front part of a top panel of a refrigerator is formed, since this part when opening the device is directly in the field of view of the beholder and thus contributes to a successful aesthetic impression.
• a second outer wall is made similarly and attached in a corresponding, reversed or mirror-inverted manner to the wall part as the first outer wall.
• a similarly favorable influence on the manufacturing costs exists, even if a third outer wall - ie the rear wall - is connected in a similar manner to the first and second outer wall.
• a manufacturing technology particularly simple way of attaching the backing part to the wall part is the Anclinchen, which is referred to in the art as clinching, Druckhegen or Toxen.
• the screw can also be fixed by means of a suitable nut resting on the backing part.
• the fastening means can also be designed as rivets and attack on the backing part.
• the wall part has a bent portion which engages behind the first section (and of course automatically also the second section), i. behind this is arranged inside the household appliance, on the one hand ensures that no gaps can arise, through which is visible in the interior of the household appliance. On the other hand, this ensures that when foaming the outer walls - and thus when lathering the backing - no foam material can escape.
• the wall part is flush with the outside of the first section on the outside and thus appears as a nearly uniform surface.
• the presence of the backing member can be further exploited to have corresponding threaded holes on which a bearing angle is screwed through screws through respective holes in the first and second sections and in the wall part to the outer wall and the wall part.
• Such bearing angle can also be used with appropriate design, possibly on the outside of the outer wall existing unsightly places, as they arise for example when attaching the backing part, for example by clinching.
• Fig. 1 shows a detail of a preferred embodiment of a household appliance according to the invention in front view
• Fig. 2 shows the detail of the preferred embodiment of the household appliance according to the invention in a perspective sectional view
• Fig. 3 shows the detail of the preferred embodiment of the household appliance according to the invention in front view, the outer wall detached from the wall part is
• FIG. 4 shows the detail of a preferred embodiment of a household appliance according to the invention in rear view
• Fig. 5 shows a detail of a fully assembled refrigerator as an example of an inventive household appliance.
• 1 to 5 show by way of example from the front a section of a refrigerator 10 as a typical example of household appliances.
• a first side or outer wall 12 arranged here on the right and a front section 20 of the top part of a top panel made of metal or metal sheet are connected to each other.
• This positioning corresponds to the orientation during normal operation of the refrigerator.
• the right side wall 12 is angled to the left by substantially 90 ° to a (not shown) left side wall toward a viewer facing the first portion 14.
• substantially at 90 ° or similar formulations, that it is not the exact observance of a specific angle, but that it can vary within the usual tolerances of the specified value.
• the first section 14 is angled at its free end by an angle of substantially 180 °, ie back to the right side wall 12, towards the inside towards a second section 16 (not visible in FIG. 1).
• a backing member 30 made of metal is clinched as a fixing aid at the right end of the wall portion 20 on the inside thereof at two locations 34 and 35 and protrudes to the right beyond the wall portion 20, abutting the second portion 16 on the inside thereof.
• the attachment of the side wall 12 to the wall portion 20 via a provided with a screw head 42 screw 40 (often called "grounding screw"), which passes through a through hole 15 in the first section 14 and a through hole 17 in the second section 16 and into a threaded hole trained to the through hole 17 aligned through hole 36 is screwed into the backing part 30.
• the through holes 15, 17 and 36 lie with their centers on a common center axis.
• Screw head 42 is not on the first portion 14, but passes through it and is in abutment with the second portion 16, the through hole 17 has a smaller diameter than the screw head 42. Therefore, the screw head 42 can not cause deformations such as dents on the first section 14.
• the through hole 15 can be covered after screwing the screw 40 with a suitable plug.
• the wall portion 20 has at its the first portion 14 facing the right end of a double-angled or cranked portion 22 which the first portion 14 partially, namely to the through hole 15, behind and behind is located between the backing member 30 and the second portion 16 (see the rear view of Fig. 4 and the illustration in Fig. 3). This avoids that during foaming material from the possibly existing gap between Schulegteil 30 and first section 14 can swell. If the portion 22 is so long that it extends to the threaded holes 31 and 36 of the backing part 30, it has according to FIG. 3 corresponding recesses for the holes, for example recess 24 for threaded bore 31. On its outer side, the wall part 20 and the first section 14 flush with each other.
• a bearing bracket 50 by means of screws 52, 54 on the side wall (here the left) attached, which is under passage through respective at least substantially aligned through holes 18, 19, 24th in the first portion 14, the second portion 16 and the wall portion 20 in a corresponding threaded bore 31 (see also Fig. 4) of the backing piece 30 and are screwed through a through hole 32 in the wall portion 20 in a further threaded bore 33 of the backing member 30 , In the finished state, the backing part 30 is then foamed.
• the present invention can be used not only in the connection of one or both side walls with a wall portion 20 of the top panel, but also to connect one or both side walls with the rear wall, so the third outer wall of the household appliance. That is, the invention is not limited in its application to the front.
• a larger amount of adhesive 60 is disposed above the backing member 30 in the corner of the first sidewall 12 to prevent leakage of material during or shortly after foaming. It goes without saying that the attachment of a second outer wall to the wall portion 20 in a corresponding, reversed or mirrored manner as the first outer wall.
