Description

The The invention relates to a household appliance with a body and one hinged by at least one hinge to the body Door, which has an outer wall and an inner wall, at their transverse edges with a connector are provided, on its side facing the body at least having a receiving space for receiving a hinge element is provided and which is bounded by a side wall. The household appliance is preferably a refrigerator or freezer.

Especially Refrigerators, such as refrigerators or Freezers, have a double-walled door with an outer and inner wall on, between which one formed with insulating foam material filled cavity is. The outer wall is often through a door panel formed, which bent at the sides in the direction of the inner wall is. At the top and / or bottom of the door the cavity is often through a connector or a door closure strip closed, the z. B. formed as a plastic injection molded part is.

The WO 2007/031416 A1 discloses a door for a household appliance with a hinge that connects body and door. The hinge comprises a hinge element with a fixed to the body mounting portion and a projecting from this support arm, at the end of a bearing element is arranged in the form of a bearing sleeve. The door has a body facing the receiving space into which the support arm of the hinge protrudes. Preferably, the receiving space is arranged in a arranged on the upper end side of the door end piece. On the support arm, a recess is formed, engages in the open position of the door, a side wall of the receiving space of the door.

The WO 2007/031469 A1 discloses a similar door for a domestic appliance with a door leaf and a hinge for hinging the door leaf to a body of the household appliance, wherein the hinge comprises a hinge pin and a hinge sleeve which rotatably engage with each other and one of the door leaf and the other fixed to a support arm is, which is intended for attachment to the body. The hinge has an opening limiting body, of which a first portion Festge on the door leaf is inserted and from which a second portion abuts in an opening-limited position of the door to the support arm.

In the solutions of WO 2007/031416 and WO 2007/031469 projects in each case a support arm of the hinge, at the end of a bearing element is arranged as a bearing sleeve, in a body facing the receiving space in a cap on the upper transverse edge of the outer and inner wall of the door. The side wall of this receiving space limits the maximum opening angle of the door, which at the hinge of the WO 2007/031416 only at a little over 90 °. In particular, when an opening limiting body is used, which also has to be accommodated between the support arm and side wall, this can greatly reduce the maximum opening angle of the door.

The Invention therefore has the task of a household appliance to provide the above-mentioned type, with a possible large opening angle of the door allows is, and which further a loadable opening limited Hinge has.

These The object is achieved in that in a generic Household appliance in the side wall a franking for at least partial reception of an opening limiting body is arranged.

There the opening limiting body in an opening limited Position of the door preferably on the body or on the body fixed part of the hinge, it limits the maximum opening angle the door. By franking the opening limiting body moved closer to the hinge or to the body become. As a result, an opening angle of more than 130 °, in particular of about 135 ° allows. Preferably, such a franking is symmetrical on both sides the door is present so that both left and right can be hinged to the carcass. That at least a hinge defines a pivot axis of the door.

The Sidewall is preferably formed by the connector. The receiving space for receiving the hinge element is therefore preferred in the Connector formed so that the side wall also is formed by the connector, so preferably not through the outside or inside wall of the door. The side wall is before given to a lateral end of the Door arranged, at least on the side, at the the door is hinged to the carcass.

The Connector is at the transverse edges of external and inner wall and preferably connects them together. It particularly preferably closes the cavity between outer and inner wall of the door to one side, in particular to the upper end of the door. In this case, that can Connector also referred to as door closure strip become.

The connecting piece is preferably closed At least to the visible front side (visible side) of the door at least largely covered by the outer wall. Particularly advantageous, the invention is thus used in doors in which the outer wall in the longitudinal direction of the door, ie in the direction of the pivot axis of the hinge to z. B. 20-60 mm higher than the inner wall. The connecting piece then bridges the step between the outer and inner walls and lies behind the outer wall when viewed from the visible side. As a result, the door has on the outside a uniform, essentially formed by the outer wall outer surface, which causes an appealing aesthetic impression.

The Clearance is preferred by a bulge or recess formed in the side wall, z. B., the side wall bulges Make the postage slightly towards the side of the door. Alternatively or additionally, the side wall also for Forming the franking in this area will be thinner than at the other areas.

1 shows as an exemplary embodiment of a household appliance, in which the invention is realized, a refrigerator 1 in stand construction with a carcass 4 and a door 2 attached to the body 4 around an axis 3 is hinged pivotally. The axis 3 runs through the door 2 parallel to an in 1 facing away from the viewer side surface of the body 4 ,

The door 2 includes an outer wall 5 , which is bent inwardly on the sides and advantageously made of sheet metal, in particular sheet metal, is formed. The resulting cavity in the door is the refrigerator inside through the inner wall 6 limited, see 2 which is advantageously molded from plastic. The between outer wall 5 and inner wall 6 formed cavity is filled with insulating foam material.

Outer and inner wall are at the upper transverse edge of the door by a connector 7 connected to each other, which simultaneously closes the cavity in the door upwards. The connector 7 has substantially an elongated cuboid shape whose length corresponds approximately to the width of the door. The height and depth of the connector 7 correspond approximately to the thickness of the door and each amount to a few cm.

Downwardly, the cavity is also bounded by a lower connector (not shown). This may be the same or different as the upper connector 7 , In the connector 7 are on both sides recording rooms 8th intended. Around the recording rooms 8th to cover up, is on the connector 7 one in the 1 and 2 not shown cover strip attached. The door is preferably mirror-symmetrical about a longitudinal axis, so that it can be hinged on both sides to the body.

2 shows the fridge the 1 with the door open. As a result, both recording rooms 8th clearly visible. On the side of the pivot axis 3 protrudes into the receiving space arranged there 8th the support arm of a hinge element 10 , which at the upper section 9 of the door 2 facing front frame of the body 4 is attached. Preferably, at the top section 9 also arranged display and / or controls for the refrigerator.

From the 1 and 2 It can also be seen that the outer wall 5 in the direction of the pivot axis 3 is longer than the inner wall 6 so that the connector 7 to the visible side in whole or in part from the outer wall 5 is covered. This indicates the door 2 outward a uniform, through the outer wall 5 formed outer surface, which causes an appealing aesthetic impression.

3 shows a perspective view of the in 2 recognizable hinge element 10 , The hinge element 10 is formed from a vertically oriented strip heavy plate and has a mounting portion 11 for attachment to the carcass 4 of the household appliance 1 and one from the mounting section 11 protruding support arm 12 on, at the end of two identical up or down protruding bearing pin 16a . 16b are arranged. In the assembly section 11 are two holes 17 to be recognized, which are provided to receive (not shown) screws, with which the hinge element 10 on the body 4 of the household appliance 1 is attached.

The pivot axis 3 runs in the longitudinal direction of the two journals 16a and 16b , The height B of the hinge element 10 in the area of the two journals 16a and 16b is slightly larger than the height of the mounting section 11 in the direction of the pivot axis 3 , Advantageously, the height B of the two journals 16a and 16b 20 mm to 40 mm, more preferably 30 mm to 35 mm. The support arm 12 tapers from the mounting section 11 to its free end, from which the two journals 16a and 16b protrude. This will ensure that the hinge element 10 the upper section 9 the front frame of the carcass 4 not overlooked, which should be only about 40 to 60 mm high, so as not to unnecessarily reduce the useful space of the refrigerator. Would the support arm 12 as in the prior art have a constant height, the journals would have to 16a and 16b taken together have a considerably greater height.

The hinge element 10 is in a plane perpendicular to that through the journals 16a . 16b defined pivot axis mirror-symmetrical. In this way, the hinge element 10 be used both for a left stop as well as for a right stop.

4 shows the hinge element 10 of the 3 in cross-section and in mirror image to that of 3 , The hinge element 10 has over its length a constant thickness d, which is about 5 mm. Based on 4 should now the preferred curvature of the support arm 12 be explained.

The on the body 4 fixed mounting section 11 is substantially straight along a line L ₁ . From the mounting section 11 is a first section 13 of the support arm 12 Angled at an obtuse angle β, which is about 105 ° ± 5 °. The first paragraph 13 initially runs essentially straight along the line L ₂ and then goes into a curved second section 14 above. The curved second section 14 goes again into a straight end section 15 over, which runs along the line L ₃ . The section 14 has a strong curvature, so that the first section 13 and the end section 15 an intermediate angle γ of less than 80 °, in the example shown of 40 ° ± 5 °. The smaller the intermediate angle γ, the greater the achievable opening angle of the door 2 ,

By the curvature of the second section 14 is the end section 15 , at the free end of the journals 16 are arranged at an angle α to the mounting portion 11 inclined towards. The inclination angle α is more than 10 °, preferably more than 20 ° and particularly preferably more than 30 °, in the example shown about 32 °.

Due to the described curvature of the support arm 12 becomes a recess 18 formed in the opening of the door, the side wall of the receiving space 8th pivots in, along the dotted line P, not just the mounting section 11 touched.

5 again shows a perspective view of the hinge element 10 , which now at the upper right corner of the front frame of the carcass 4 a household appliance is attached. These are in the upper section 9 of the front frame Ge wind holes for the holes 17 provided by continuous screws. 5 shows a right stop of the door, so that the support arm 12 bent to the right.

In 5 it can be seen that the support arm 12 from the mounting section 11 tapers towards its free end, on a mirror-symmetrical to a plane perpendicular to the pivot axis. The rejuvenation is strongest in the first section 13 , then sits down in the second section 14 continues while the end section 15 only slightly tapered or even has a constant height. The taper in the first and between section is approximately linear, ie in a spread on a plane support arm 12 approximately along a straight line, until the transition to the end section 15 , An exponential from the mounting section 11 to the end section 15 decreasing rejuvenation is also conceivable.

6 shows one to 5 comparable representation, in which now on the lower journals 16b a bearing bolt 20 is attached. A cross section of the bearing pin 20 along the line VII is in 7 shown. The bearing bolt 20 has a lower portion with circular cylindrical outer surface, which is provided for storage in a bearing eye fixed to the door. On the top is a bowl-like section on one side 19 which serves as a cable duct and as a lining for the end portion of the hinge element 10 serves.

How out 7 can be seen, is in the bearing pin 20 a square cross-section hole 22 provided, which the journal 16b without play. Adjacent to the hole 22 is a parallel to the pivot axis extending cable channel 21 arranged with oval or any cross-section, which is used to guide cables from the carcass 4 in the door 2 is provided. Preferably, the cable channel 21 and the hole 22 continuous. The bearing bolt 20 is made as an injection molded part of a plastic with a low coefficient of friction such as polyoxymethylene (POM).

8th shows a perspective view into the receiving space 8th in the upper right corner of the door 2 , from the corpus 4 seen from. The upper section including the cover strip of the door 2 is cut off for better visibility. Down is the inner wall 6 recognizable, at the outer edges of a magnetic seal 29 is arranged. Above the inner wall 6 closes the connector 7 at. Behind it is the outer wall 5 arranged facing to an outside wall side portion 25 is bent over. Together with a side wall section 51 of the connector 7 forms the outer wall side portion 25 thus the side wall 28 of the recording room 8th in the door 2 ,

The recording room 8th also has a bottom wall 37 and a wall 38 to the visible side of the door, into which a bag 39 is admitted. In the area of the bag 39 the wall runs 39 parallel to and very close or adjacent to the outer wall 5 ,

In the connector 7 is also the bearing eye 24 by forming a bearing sleeve 23 formed, in which the bearing bolt 20 (in 8th not shown).

Finally, in 8th an opening limiting body 30 seen, which is formed by a wire element, which has an approximately parallel to the pivot axis extending first portion 32 having. This first section 32 engages behind the support arm 12 and thereby defines an opening-limited position of the door. At the other end of the opening limiting body 30 is a second section 34 is curved into a loop and in a hollow 35 in the ground 37 of the connector 7 added. As a result, it is fixed positively to the door. In the middle of the eyelet is the second section 34 additionally by a screw 31 attached. A middle thigh 33 of the opening limiting body 30 runs along one opposite the pivot axis 3 obliquely oriented support surface 36 who are also in the ground 37 of the connector 7 is formed.

9 shows how 6 a perspective view of the upper right corner of the refrigerator 1 , with hinged door. In contrast to 6 is the lower portion of the bearing pin 20 in the bearing sleeve 23 of the bearing eye 24 swivel-mounted. Here, the first section engages behind 32 of the opening limiting body 30 the support arm 12 and is therefore in 9 covered. Upstairs is the recording room 8th through a cover strip 43 covered.

Further shows 9 a cable bundle 45 which passes through the cable channel 21 in the bearing bolt 20 in the cavity of the door 2 is guided.

10 also shows a perspective view of the upper right corner of the refrigerator with hinged door, but without cable bundle 45 and with removed cover strip 43 , Furthermore, in 10 the panels of the hinge element shown, which by plastic elements 40 . 41 and 42 be formed.

In addition, in 10 the lower portion of the bearing sleeve 23 to recognize in the between outer wall 5 and inner wall 6 formed cavity protrudes and through the cable into the door 2 can be performed.

11 and 12 show cross-sections perpendicular to the pivot axis through the hinge element 10 with hinged door with door open ( 11 ) and closed door ( 12 ). The pivot axis 3 runs in each case through the axis of the bearing pin 20 ,

In the sectional views are the upwardly projecting section 19 of the bearing bolt 20 , a cut cable bundle 45 and a screw 26 recognizable, with the mounting section 11 is attached to the body of a household appliance (not shown). Any panels of the hinge element are not shown for purposes of clarity. The opening limiting body 30 is visible from above, as well as the trough 35 in which its second section 34 is fixed. To the visible side is the connector 7 through an outer wall 5 covered on the lateral end side of the door inwardly to form the outer wall side portion 25 is bent over. Behind the outside wall 5 and partly parallel to the front wall runs 38 of the connector 7 , which at the lateral end of the door also to form the section 55 curved inwards.

How out 11 can be seen, the first section intervenes 32 of the opening limiting body 30 behind the support arm 12 and beats there in the opening-limited position of the door in the area between the second section 14 and the end section 15 of the support arm 12 at. In this wide open position pivots the side wall 28 of the recording room 8th in the recess formed by the curvature of the support arm 12 into it. The sections 13 . 14 and 15 of the support arm 12 are curved so that the side wall 28 when opening the door not on the support arm 12 although it describes along the dotted line P an arc of up to 135 °. In order to allow a particularly large opening angle, the first section 32 of the opening limiting body 30 furthermore in a franking 52 in the sidewall 28 arranged so that he even with large opening angle the support arm 12 engages behind.

The franking 52 is due to a bulge in the wall of the connector 7 formed, see 12 , In particular, the section 55 the front wall 38 in the area of franking 52 angled outwardly to an outwardly offset side wall portion 51 to build. At this point is the outer wall side section 25 recessed, so that the side wall section 51 of the connector 7 forms the visible to the outside wall of the door. In order nevertheless to achieve a uniform visible side of the door, the side wall section runs 51 parallel and slightly overlapping, but approximately flush with the outer wall side portion 25 ,

At the in 12 illustrated closed position of the door protrudes the curved portion 14 of the support arm 12 in the pocket 39 into it, which in the wall 38 of the connector 7 is formed. Through the bag 39 it is possible the first section 13 especially long and the curvature of the second section 14 particularly strong form, which allows a particularly large opening angle of the door.

Based on 13 and 14 will now be explained in more detail the elastic movement of the opening limiting body.

13 shows a section through the connector 7 on which the opening limiting body 30 rests. The thigh 33 is against the sloping contact surface 36 supported, while the first section at the bend 46 is angled upwards. The second section 34 is at the bend 48 from the thigh 33 angled and through the screw 31 at the connector 7 and thus attached to the door.

The same parts are highly schematized also in 14 reproduced in side view, with the sections 32 . 33 and the thigh 34 of the opening limiting body 30 shown here only as dashes. The solid lines represent the opening boundary body 30 in the rest position. The dashed lines represent the shape of the opening limiting body 30 in a state in which the door strikes in its opening-limited position. Then by the support arm 12 a force F ₁ on the first section 32 exercised. The transmitted kinetic energy is absorbed in two spring lines, which in the 13 and 14 with R ₁ and R _{2 are} designated.

Depending on which distance from the bend 46 the force F ₁ at the first section 32 attacks, the first section 32 spring in the direction R ₁ , bending in that direction. Because the first section 32 is relatively short (about 5 to 10 mm), it will bend only slightly. In addition, possibly also the radius of curvature at the bend 46 increase elastically. The maximum deflection of the first section 32 in the direction R ₁ is about 0.3 to 1 mm. To make room for this deflection is the top section 32 from the sidewall portion 51 separated by a gap. The gap has a width e of about 0.5 to 2 mm, preferably about 1 ± 0.2 mm.

On the other hand, the thigh arches 33 - and possibly also the second section 34 - Up in the direction indicated by R ₂ direction. This supports the thigh 33 in the area of the bend 46 on the support surface 36 off, leaving a force on the support surface 36 acts, see arrow F ₂ . In addition, if necessary, a tensile force acts on the second section 34 which is derived on the trough enclosing the eyelet. Due to the relatively long length of the thigh 33 (about 20-30 mm) he will visibly arch, namely z. B. about about 0.2 to 2 mm in the direction of R ₂ . Here, the leg and possibly also the second section bend 34 and thereby absorb spring energy. Furthermore, the radius of curvature at the bend 48 and thus the angle of curvature 48 be elastically enlarged, as in 14 to recognize.

The configuration of the franking should be based on the 15 and 16 will be explained again in detail. 15 is the same representation as 8th , So a perspective view of the recording room 8th partially cut away side and front wall. 16 shows a comparable representation from a similar perspective, but without the cut. Thus, also the upper part of the connector 7 recognizable, which upwards from an end flange 59 , the so-called cathedral, is completed. On top of this, an upper cover strip will be installed after installation 43 placed.

Coming back to 15 , the first section extends 32 of the opening limiting body 30 in the postage 52 , As related to 13 he already mentioned, is the first section 32 through a gap from the side wall portion 51 of the connector 7 spaced to resiliently to be able to spring in this direction.

To the front (visible side) of the door is the connecting piece of the outer wall 5 covered, which is formed here by a door panel. On the side this is to form the outer wall side section 25 bent inwards. The connector 7 also has a front wall 38 on the side inward to section 55 is bent over. At the edge of the outer wall side section 25 is the section 55 to a short wall section 56 Angled, which the franking 52 Limited to the front. To the wall section 56 is on the one hand the side wall section 51 attached, which extends in the direction of the body and a second boundary of the franking 52 forms. The franking 52 is open on two sides. How out 16 is apparent, it has an approximately rectangular cross-section and extends over the entire height of the connecting piece, to the end flange 59 ,

From the wall section 56 further extends to the front side of the section 58 that together with the wall section 55 forms a groove for receiving the edge of the outer wall side portion 25 serves.

The 17 and 18 show a perspective view of the connector 7 , pulled apart from the outer wall 5 , in which 17 a view from the top right and 18 represents a view from the bottom right.

In addition to the features already described above is in the 17 and 18 the shape of the outer wall 5 particularly well visible, which on the side to form an outer wall side portion 25 is bent over. However, the top corner of the outer wall side section is at 62 spared. In the area 62 becomes the outwardly visible wall of the door through the outside of the side wall portion 51 of the connector 7 educated.

Furthermore, in 17 the bottom of the connector 7 recognizable. This has a wall portion facing the body 73 and two stability walls 74 . 75 on. Below the body section facing the wall 73 closes the inner wall 6 (not shown) of the door. The bottom wall 37 of the recording room 8th is through these walls 74 . 75 covered. The bearing bush 23 extends from the bearing eye 24 down into the cavity so that cables can be routed from the carcass into the door. Between the socket 23 and the sidewall portion 51 of the recording room 8th sticking out a rib 71 down to where a catch 70 is trained. When mounted, the locking nose engages behind with its locking surface 80 an edge of a first folded portion 77 the outer wall 5 , what a 17 hidden, but in 18 is recognizable.

According to 18 is the outer wall 5 on the left side of the door to an outside wall side section 25 bent, which is approximately perpendicular to the visible surface or front side of the door, from the outer wall 5 is formed. At the inward end is the outer wall side portion 25 turn to a first fold section 77 angled. This runs at its edge approximately parallel to the outer wall side portion 25 so its edge 82 the visible surface of the door is facing.

When placing the connector 7 on the sidewall 5 engages the latch hook 70 with its catch surface 80 behind the locking edge 82 of the first folded section 77 and thus creates a positive connection.

This pushes the side wall section 51 of the recording room 8th in the area 62 in which in the outer wall 5 a recess is formed. The side wall section overlaps 51 easily the outside wall side section 25 to create a flush, continuous outer surface.

Above is the door panel to form the fold 63 bent slightly inwards. When placing the connector 7 pushes the fold 63 in one in the end flange 59 formed groove.
