Description

Technical Field

[0001] One aspect of the invention relates to a household appliance with a housing. At least one food receiving space is constructed within the housing. The household appliance has at least one hinge disposed on the front portion of the housing. Furthermore, the household appliance also has a door disposed on the hinge. Thus, the door is pivotally disposed relative to the housing. Another aspect of the invention relates to a method. Background Technology

[0002] Household appliances, such as household refrigeration appliances, are known. These appliances typically have a housing with a door that is pivotally mounted thereon. To achieve this pivotability, a hinge is implemented. This hinge has a support angle. In this case, there is also a design in which the support angle is located on the front side of the door. For example, the support angle is screwed onto the front flange of the housing. This design is known, for example, from document EP 1 679 481 A2. This support angle has an elongated, horizontal track by which the support angle is directly fastened to the front side of the housing. Furthermore, the support angle, viewed along its width, has support bolts asymmetrically arranged with respect to the track. The door is supported on these support bolts. This completely asymmetrical support angle allows the door to be assembled in only one hinge direction.

[0003] Furthermore, document DE 203 12 282U1 discloses a hinge mechanism for a household refrigeration appliance. The hinge mechanism has a support base that can be screwed onto the body of the household refrigeration appliance. The support base has a vertically oriented plate through which the support base can be screwed onto the body. The plate has two separate, spaced-apart mounting holes along its width, through which bolts can be guided. Additionally, the support base has two separate support members arranged side-by-side along its width. A support bolt, independent of the support members, can be inserted into and secured to one of these support members, specifically screwed into it. A support bushing can be rotatably inserted into the support bolt, and this support bushing can be secured in the door. The two support members are offset from the mounting holes. Moreover, this support angle can only be installed and used in a specific location on the housing.

[0004] Therefore, among the known hinge designs, different designs are needed, one that is mounted on the housing on the left and the other on the right, so that doors that can swing differently in this respect can be fitted. On the one hand, this increases research and development costs, and on the other hand, it also increases manufacturing and assembly costs. Summary of the Invention

[0005] The object of the present invention is to realize a household appliance in which the hinges are improved in terms of applicability and support for doors with different hinge types.

[0006] This objective is achieved by the household appliances and methods according to the present invention.

[0007] One aspect of the invention relates to a household appliance having a housing. At least one food receiving space is constructed within the housing. Furthermore, the household appliance has at least one hinge. This hinge is disposed on the front portion of the housing. Additionally, the household appliance also has a door. This door is disposed on the hinge and thus pivotally positioned relative to the housing. The hinge has a support angle, which is secured to the end side of the front portion by at least one fastener. This support angle is symmetrically configured when viewed from the front of the household appliance.

[0008] A symmetrical structure specifically means that the functionally important features of the support angle are arranged symmetrically with respect to each other. Symmetry should be considered specifically as a vertical axis about the support angle. In particular, the vertical axis extends along the height direction of the household appliance. The functional features of the support angle are particularly those relating to the load-bearing and / or retaining functions for components independent of the support angle, and / or those relating to the connection function between the support angle and another component of the household appliance. Such features are, for example, support bolts or support pins for doors and / or at least one hole through which fasteners, particularly bolts, can pass, thereby securing the support angle to a component of the household appliance, particularly the housing. In one embodiment, the support angle is symmetrical only with respect to this feature. Thus, the support angle is symmetrical only with respect to the component. The support angle can also be asymmetrical with respect to other features, such as the form of a support plate or coupling plate and / or abutment plate.

[0009] However, the support angle can also be symmetrical in this respect and therefore completely symmetrical in one embodiment. Thus, the support angle is not merely symmetrical about the component.

[0010] Therefore, the support angle is configured to be selectively mounted on the left side of the front part along the width direction and viewed from the front of the household appliance, or on the right side of the front part. Thus, in both mounting configurations of the door on the support angle, the door, in the closed state, is positioned on the housing at the same location along both the height and width directions of the household appliance.

[0011] Therefore, with this symmetrical support angle, the support angle can be installed on the front end side of the housing not only on the right side but also on the left side. Thus, only one variation of the support angle is needed to create different variations of the household appliance in terms of the opening side of the door. Therefore, this support angle can be used not only for household appliances in which the door can rotate about a vertical axis of rotation (on the left side when viewed from the front), but also for household appliances in which the door (when viewed from the front) should be able to swing about a vertical axis of rotation on the right side. The support angle is symmetrically configured when viewed from the front of the household appliance along the width direction. Through this width symmetry, on the one hand, the installation position of the support angle on the left end side, and particularly with respect to the left end of the housing, can be configured to have the same interval as the corresponding right-side installation; thus, in the case of right-side installation, the support angle has the same interval as the right end of the housing. Therefore, regardless of whether the door is to be installed as a left-side hinged or right-side hinged door according to the invention, the door can always be positioned on the housing at the same height and width.

[0012] This is particularly applicable when a receiving portion on the front of the housing—designed to receive fasteners—is configured with equal spacing between its corresponding adjacent ends or walls on the left and right sides of the housing. This means, for example, in the case of a receiving portion configured as a threaded hole on the left side for a bolt as a fastener, the spacing along the width direction from the left end of the housing is equal to the spacing with the corresponding fastener configured on the right side, which is disposed or configured adjacent to the right edge of the housing. Therefore, if such a fastener receiving portion is also configured on the front of the housing in a manner symmetrical about the middle of the front of the housing, then a mounting position with the support angle symmetrical about the middle of the housing or the middle of the front of the housing can also be achieved through this support angle, which is symmetrical about the width direction in this respect.

[0013] Therefore, this flip-symmetrical positioning of the door on the front of the housing can be achieved in a particularly simple way. Assembly is also simplified by using the same components in the form of symmetrical support angles. That is, it is no longer necessary to consider how the door should be hinged and which support angle is specifically required for this purpose; instead, the same support angle can always be used.

[0014] In one embodiment, the support angle is configured symmetrically about an axis of symmetry oriented along the height direction of the household appliance.

[0015] In one embodiment, the support angle has a backing plate that rests directly against the front end side. Specifically, the backing plate rests completely against that end side. This means that maximum support is provided by the backing plate on that end side. This allows for a particularly stable fastening of the support angle.

[0016] In particular, when viewed along the depth direction of the household appliance, the support angle is positioned to project forward from the end side. Therefore, the support angle does not extend backward beyond the end side, but only forward. In particular, the backing plate is the last component where the support angle is positioned along the depth direction.

[0017] In one embodiment, the support angle, in addition to the abutment plate, also has a bearing plate that bends forward at an angle from it. This bearing plate is configured to support a support bolt that extends along the height direction. The support bolt is also a component of the support angle.

[0018] In particular, the mating plate and the supporting plate form an L-shape.

[0019] In one embodiment, the backing plate has at least two holes spaced apart from each other when viewed along the width direction of the household appliance, said holes for guiding fasteners, particularly bolts. In one embodiment, the two holes are located at the same height when viewed along the height direction of the household appliance on the backing plate. However, it is also possible to configure it to have a height difference in this respect.

[0020] In particular, these holes are configured symmetrically about the vertical axis of the support angle, which is located at the middle of the support angle when viewed from the front.

[0021] In particular, these holes are therefore symmetrically arranged about the middle of the mounting plate.

[0022] In this respect, "middle" should be understood as along the width direction.

[0023] In one embodiment, the support corner has a support bolt. The support bolt is specifically formed as a single piece on the support corner. "Single piece" here and hereinafter should be understood in particular as formed from a single component, for example, by casting, injection molding, or molding. The support bolt preferably extends along the height direction. The support bolt is positioned forward, offset from the backing plate, when viewed along the depth direction of the household appliance. The support bolt is particularly integrated into the aforementioned support plate. In particular, the support bolt extends perpendicularly to a plane in which the support plate extends, with its longitudinal axis—which is specifically oriented along the height direction of the household appliance. When viewed along the width direction of the household appliance, in a frontal projection or projection onto the backing plate, the support bolt is positioned centrally with respect to the backing plate, particularly with respect to the entire support corner. If holes are provided in the backing plate (e.g., for securing the support corner), the support bolt can be positioned centrally between the holes in the backing plate, when viewed along the width direction of the household appliance, in a frontal projection or projection onto the backing plate. Therefore, when viewed from the front of the household appliance and thus also from the front of the support angle, these holes, when viewed along the width direction in the backing plate, are symmetrical about the support bolt. In particular, an axis of symmetry extending along the height direction can be seen in this respect. This means that, in this front-view projection, the interval measured along the width direction between the axis of symmetry of the support bolt and one hole is equal to the corresponding interval between the axis of symmetry and the other hole. In this case, the support bolt is symmetrically arranged about this axis of symmetry. This design is particularly advantageous because the aforementioned installation can be achieved particularly easily through this symmetrical structure between the support bolt and the hole arranged on its side relative to it when viewed from the front. On the one hand, the support angle itself is simple and symmetrically arranged. On the other hand, the support angle can be assembled particularly easily, and the door can be supported on it accordingly. However, it is precisely this symmetrical relationship between the support bolt positioned in the middle and the hole symmetrically arranged relative to it along the width direction that allows for the very simple realization of the flip-symmetrical installation of the support angle on the front end side of the housing. It is by utilizing the aforementioned design of the receiving portion for fasteners on the front end side that a height-symmetrical installation scheme for the door can be achieved.

[0024] In one embodiment, the support bolt, viewed along the width of the household appliance, is smaller than the minimum interval measured along the width between the two holes. This is another highly advantageous implementation. This is because the fastener can be easily inserted and fitted into the hole without the support bolt obstructing the view along the depth direction. Thus, the fastener can be easily inserted and secured into the hole below the support bolt by extending a tool alongside it. This is particularly advantageous in the case of bolts that subsequently need to be tightened.

[0025] Thus, under projected observation, it is found that the support bolts do not completely overlap with these holes along the width direction, and in particular, there is no overlap at all.

[0026] In one embodiment, the support angle, particularly the support bolt, defines the rotation axis of the door, which is disposed thereon. This rotation axis, viewed from the front of the appliance and projected onto the backing plate, is positioned midway between the holes. This is another advantageous embodiment because the angle is always formed such that the provided rotation axis for the door is symmetrical about these holes. This also allows for a corresponding flip-symmetrical installation of the support angle on the left or right side of the front of the door, and subsequently, for both positions, the same relative position of the door to the housing can be achieved.

[0027] In one embodiment, the support angle has at least one, particularly integrated, positioning element. This positioning element, viewed along the depth direction of the household appliance, is positioned further rearward than the backing plate. In one embodiment, the positioning element extends into a receiving or guiding portion in the front end side of the housing. This achieves further mechanical coupling between the support angle and the housing, particularly a form-locking coupling (e.g., a gapless form-locking coupling). Therefore, it also improves or enables the torsional resistance of the support angle about an axis oriented along the depth direction. The fixation of the support angle's position on the front end side of the housing is thus further improved. In one embodiment, viewed along the height direction, the positioning element is located at a different height than the hole in the backing plate. This also supports the fixation of the support angle's position on the front end side. The guiding portion can be formed through a receiving portion or a hole, such as a blind hole.

[0028] In one embodiment, the hinge has a cable guide. Through this cable guide, at least one cable of the household appliance can be routed or laid between the door and the housing, as specified. This is another advantageous embodiment. Because this also allows the supply of power signals and / or digital signals and / or analog control signals to components located in the door. This enables electronic components in the door to exchange signals with components in the housing, and in particular, to communicate. The proposed solution is particularly advantageous in this design of the household appliance, because the cable guide is thus installed in the hinge and is also space-saving and compactly arranged therein. Therefore, the interface already existing between the door and the housing, formed by the hinge, can be utilized in a multi-functional manner.

[0029] In one embodiment, the support angle has an integrated support bolt. "Integrated" here and hereinafter should be understood as meaning that the two components are integrally formed, i.e., one-piece. The hinge has a bushing independent of the support angle. This bushing has, in particular, at least one insertion channel. This insertion channel is specifically configured for inserting the support bolt into the bushing. Therefore, the support bolt, in the installed state, engages with this insertion channel. This also achieves the corresponding mechanical coupling.

[0030] In one embodiment, the insertion channel has an inner contour including a clamping structure. This clamping structure is configured to clamp and retain the bushing with the support bolt. This achieves a highly effective mechanical coupling between the bushing and the support bolt. In particular, it also achieves anti-torsional coupling between the bushing and the support bolt. This prevents relative rotational movement between the bushing and the support bolt, especially about the rotation axis of the door.

[0031] In one embodiment, the clamping structure has at least one clamping pin, particularly two clamping pins, which interact clampingly with the outer side of the support bolt.

[0032] In one embodiment, the bushing is part of the cable guiding device. This bushing then has a cable threading device. This cable threading device can specifically be a cable channel. Therefore, the cable threading device is configured to allow the cable to pass through. Thus, the cable is also specifically protected in its arrangement and guidance. Therefore, even when the door swings relative to the support angle, undesirable mechanical effects on the cable are avoided. This prevents bending or rubbing of the cable during such door movement.

[0033] In one embodiment, the bushing's insertion channel is separate from the bushing's cable threading device. This means that the channels in this respect are spaced apart. Therefore, the cable is supported in a different channel than the support pin that fits into the bushing. This also avoids unwanted damage to the cable. On the other hand, this also allows the bushing to be mechanically and stably connected to the support pin. The coupling force required for this can be generated independently of the cable, which is preferably laid in a different channel, i.e., the cable channel.

[0034] In one embodiment, the bushing is torsionally secured to its support bolt.

[0035] In one embodiment, the support angle is made of a single piece, particularly metal. The support angle preferably includes a backing plate, the aforementioned bearing plate, and a support bolt.

[0036] In one embodiment, the support bolt has a square shape.

[0037] In one embodiment, the hinge has an adapter independent of the support angle. This adapter is torsionally mounted on the support pin of the support angle. A preferred bushing of the hinge is arranged, viewed along the height direction, to sit on its independent adapter. Thus, in this embodiment, mutually independent components are stacked in the form of bushings and adapters on the support angle, which is also independent of it, particularly inserted into and stacked on the support pin.

[0038] In one embodiment, the adapter engages with a spring, particularly a plastic spring from a household refrigeration unit. The plastic spring is fastened to the door and slides onto the adapter, which is fastened to the hinge, when the door is closed. This generates a torque acting on the door, which closes the door from an opening angle or keeps it closed. Furthermore, in one embodiment, a stopper is mounted on the door together with the plastic spring. This stopper abuts against the adapter and stops the door at an opening angle. Thus, the household refrigeration unit also has a semi-automatic closing function.

[0039] In one embodiment of the hinge without an adapter, a support angle without a closing function is achieved. If the hinge has the additional adapter, then a support angle with a closing function is achieved.

[0040] In another embodiment, the support angle has a horizontally oriented support plate or coupling plate, as already mentioned. In one embodiment, a leg, independent of the support angle, is directly mounted, particularly fastened, onto the coupling plate. Specifically, the leg is screwed onto the coupling plate. For this purpose, the coupling plate has threaded holes into which the leg can be screwed using screws. This design not only achieves fastening of the leg to the support angle but also allows for horizontal adjustment of the leg, which can be adjusted according to the screw-in position of the leg into the threaded hole.

[0041] Specifically, the coupling plate can be configured to have a first segment at a first height level (H1) and a second segment at a second height level (H2) different from the first height level (H1). The height level is measured along the height direction (y-direction) of the household appliance. The first segment and / or the second segment are preferably substantially or completely flat (not considering, for example, additional embossing to improve rigidity) and / or preferably horizontally oriented. This design not only improves the stability of the support angle, but also allows for a region of the support angle that advantageously enables different functions by using two segments staggered along the height direction. Thus, in particular, the first height level (H1) can be configured to be greater than the second height level (H2), and the support bolt can be formed on or adjacent to the first segment, while the threaded hole for receiving the support leg is formed in the second segment. This allows the threaded hole to be deeper relative to the support bolt (or the first segment). In particular, the threaded hole can be configured to be completely below the first height level (H1). This method also allows for sufficient spacing between the upper end of the threaded bolt on one side and the lower end of the door on the other side, even with the legs fully screwed in. Therefore, the threaded bolt will not collide with the door. However, sufficient adaptation to the device height can still be achieved via the legs on the other side. In one embodiment, the support angle is made of metal. The support angle can particularly be a sheet metal angle.

[0042] In one embodiment, the individual adapter is torsionally mounted on the support bolt. For this purpose, the adapter has a through-hole through which the support bolt extends. Additionally, the adapter can also be screwed onto a support angle, particularly a coupling plate or a load-bearing plate. Thus, in one embodiment, a bushing is inserted into the adapter; this bushing can also be referred to herein as a closure bushing. Moreover, this bushing is also inserted into the support bolt.

[0043] In one embodiment, the holes in the abutment plate are arranged such that they are accessible even when the bushing is already fitted onto the support bolt, and bolts can be inserted into the holes in the abutment plate using a tool, such as a screwdriver. Therefore, this can also be achieved, particularly along the depth direction of the household appliance, and allows for the corresponding mounting of bolts along the depth direction next to the bushing.

[0044] In particular, in the variant without fittings, the hinge is configured such that if the door is already mounted on the hinge, the holes in the abutment plate are also accessible. Furthermore, this allows access to these holes and the installation of bolts, which can then be screwed on accordingly using tools.

[0045] The aforementioned embodiment with at least one locating element at the support angle can also be implemented in such a way that multiple locating elements exist. Because this support angle is produced by forming and / or stamping, these locating elements can also be produced cost-neutrally. These locating elements can be simply produced together during the forming and / or stamping process. In particular, no additional material is required for this.

[0046] However, in another embodiment, the positioning element can also be formed by a separate pin, which is inseparably mounted in the support angle. For example, it can be configured to be pressed into a receiving hole in the abutment plate.

[0047] In one embodiment, the coupling plate may have an embossed portion. This improves torsional stiffness.

[0048] In one embodiment, the adapter has a recess that is open on the edge side. This simplifies the process of guiding the cable alongside the adapter. Thus, in this embodiment, the cable does not necessarily need to be guided through a hole that is closed around the periphery or on the surrounding side.

[0049] In one embodiment, the cross-section of the cable threading device in the bushing is not circular, but rather elliptical.

[0050] Viewed along the height direction, the upper and / or lower ends of the cable threading device can be rounded. This avoids sharp edges or corners, thus preventing damage to the cable. In one embodiment, the adapter is configured for symmetrical mounting on the support corner. Therefore, in the event of a door hinge change, the adapter can be removed from the support corner, rotated 180°, and then remounted on the support corner.

[0051] In one embodiment, the abutment plate protrudes from the coupling plate or bearing plate in the same direction as the support bolt when viewed along the height direction. This creates a U-shaped support angle. Since the support bolt and the abutment plate protrude from the coupling plate or bearing plate in almost the same direction, the height of the support angle is reduced compared to the embodiment where the support bolt protrudes from the coupling plate in a positive height direction and the abutment plate protrudes from the coupling plate in a negative height direction.

[0052] The hinge design also improves the automatic fastening, such as adhesive bonding, of the bottom of the appliance's housing, particularly the base plate. This eliminates the need for space for hinges that screw onto the bottom of the appliance. Fastening and screwing of the support angles are achieved only from the front, or only on the front end. Furthermore, the mounting position of the appliance's feet is no longer directly on the housing, but also on the support angle, meaning that the feet no longer need to be fitted under the housing during assembly. Therefore, the mounting position of the feet moves forward when viewed in the depth direction. This also prevents damage to the bottom of the housing, especially if the housing is made of cardboard. It also improves the protection of the door from damage during assembly via pads or feet. Moreover, it reduces the possibility of the appliance tipping over when the feet are installed.

[0053] With an advantageous embodiment having a cable-passing device in the hinge, it is now also simple to install electrical components, operating and / or display units and / or cameras or the like in the door. In the advantageous embodiment, the cable simply passes through an advantageously designed bushing, instead of having to be extensively guided through other parts of the hinge.

[0054] Furthermore, the aforementioned embodiment also realizes a standard system as a hinge that can be used not only in household appliances with such cables but also in household appliances without such cables. Similarly, this can be achieved not only for devices with closures in the hinge area but also for devices without such closures in the hinge area.

[0055] Another aspect of the present invention relates to a method for manufacturing household appliances, wherein the following steps are performed:

[0056] - Provide a housing for a household appliance, wherein at least one receiving space for food is constructed within the housing;

[0057] - Provide at least one symmetrical support angle for the hinge of the household appliance, wherein the hinge is configured as a door for receiving the household appliance, such that the door can swing relative to the housing in the assembled state.

[0058] - A variation of the household appliance with respect to the hinge side of the door can be selectively produced by mounting a symmetrical support angle on either the left or right side of the front of the housing; and in both possible mounting cases, particularly due to the symmetrical structure of the support angle, the door positioned on the symmetrical support angle is automatically positioned relative to the housing in the height and width directions of the household appliance when closed.

[0059] Using this method, installation on two different sides of the front can be achieved with the same support angle, and the door can still be positioned identically relative to the housing. This allows for simple modifications to how the hinges of the door are set in household appliances.

[0060] Advantageous embodiments of the aforementioned household appliance can be considered advantageous embodiments of the method. Specific elements and / or the given element locations can individually or effectively connect to implement particular method steps.

[0061] The positioning and orientation of a door or equipment are described by specifying "up", "down", "front", "back", "horizontal", "vertical", "depth", "width", and "height" to indicate its proper use and arrangement.

[0062] Further features of this invention arise from the technical solutions, drawings, and descriptions of the drawings. Features and combinations of features previously described in the specification, as well as features and combinations of features mentioned in the description of the drawings and / or shown separately in the drawings, can be used not only in their respective proposed combinations but also in other combinations without departing from the scope of protection of this invention. Therefore, the following embodiments, which are not explicitly shown or illustrated in the drawings but are known and can be derived from separate combinations of features derived from the illustrated embodiments, can also be considered as included and disclosed by this invention. Therefore, the following embodiments and combinations of features can also be considered as disclosed, which do not possess all the features of the technical solutions of the originally drafted invention. Furthermore, the following embodiments and combinations of features (particularly through the above embodiments) can also be considered as disclosed, which exceed or differ from the combinations of features described in the technical solutions of this invention.

[0080] exist Figure 1 The diagram illustrates a household appliance 1. Household appliance 1 can be, for example, a cooking appliance, such as a microwave cooking appliance, a steam cooking appliance, or an oven. However, household appliance 1 can also be, for example, a bottle storage cabinet, such as a wine cabinet.

[0081] In particular, in one embodiment, household appliance 1 is a household refrigeration appliance. Thus, this household appliance is configured for storing and preserving food. In this case, the household appliance may be, for example, a refrigeration appliance, a freezing appliance, or a refrigeration-freezing combination appliance.

[0082] Household appliance 1 has a housing 2. At least one receiving space 3 for food is constructed within the housing 2. In this case, the food can be edible or drinkable.

[0083] Receiving space 3 is designated for food storage as per regulations.

[0084] In addition, the household appliance 1 has a door 4. The door 4 is movably mounted on the housing 2. The door 4 is configured to close the receiving space 3.

[0085] The household appliance 1 has at least one hinge 5. The hinge 5 is disposed on the front 6 of the housing 2. In this embodiment, the door 4 is disposed in the housing 2 by another hinge 7. These hinges 5 and 7 allow the door 4 to swing relative to the housing 2 about a vertical axis A—which is oriented along the height direction (y direction) of the household appliance 1. The door 4 is disposed directly on the hinges 5 and 7.

[0086] The front portion 6 has an end side 8. The hinges 5 and 7 are directly fastened to this end side 8. Therefore, the hinges 5 and 7 are fastened to the housing 2 only on the front side.

[0087] Viewed along its width (x-direction), the housing 2 has two opposing ends 9 and 10, which are here in the form of sidewalls. In one embodiment, these opposing ends 9 and 10 are formed by vertical sidewalls. These opposing ends 9 and 10 are, in particular, the side boundaries of the housing 2.

[0088] Hinges 5 and 7 are detachably fastened to the front portion 6 of the housing 2. In particular, these hinges are screwed onto the front portion.

[0089] Generally, at least one hinge 5, 7 is configured to be mounted on the front portion 6 in a flip-symmetrical manner. This means that such hinge 5, when viewed from the front and thus when looking at the insertion opening of the receiving space 3 with the door 4 open and when looking at the door 4 closed, can be mounted on the front portion 6 either on the left side and thus adjacent to the first end 9 of the housing 2, or on the right side and thus adjacent to the opposite end 10 of the housing 2. Figure 1In the illustrated embodiment, door 4 is hinged on the left side when viewed from the front. This means that hinges 5 and 7 are located on the left side and therefore adjacent to the first end 9 on the front portion 6. Thus, hinges 5 and 7 can be selectively mounted on either the left end 8a or the right end 8b of the front portion 6. In both mounting cases, door 4, subsequently fastened thereto, is positioned on the housing 2 in the closed state along the height and width directions of the household appliance 1.

[0090] exist Figure 1 The diagram illustrates a first receiving portion 11 and a second receiving portion 12. Receiving portions 11 and 12 are specifically bolt receiving portions for bolts, where the bolt represents a fastener. These receiving portions 11 and 12 are here configured on the right end side 8b. Accordingly, in another embodiment, two such receiving portions may also be configured on the right side. These receiving portions are... Figure 1 It is not visible in the middle because hinge 5 is fastened to it.

[0091] As in Figure 1 As can also be seen in the upper region, a corresponding design with receiving parts 13 and 14 is also implemented. This applies accordingly to the arrangement shown in the region of hinge 7.

[0092] In one embodiment, the interval a1 measured along the width direction (x-direction) between the receiving portion 11 and the adjacent end portion 10 is specifically the same as the corresponding interval of the receiving portion in the case of the hinge 5. This means that, in one embodiment, two such receiving portions 11, 12 are also provided on the left end side 8a, to which the hinge 5 is fastened. Moreover, there, the interval measured along the width direction between the outer receiving portion 11 and the adjacent first end portion 9 corresponds to the interval a1.

[0093] In one embodiment, this also applies to such a horizontal spacing between the inner receiving portion 12 and the adjacent second end 10, and similarly applies to... Figure 1 The hinge 5 forms another internal receiving part 12 with a corresponding interval relative to the end 9.

[0094] It can be configured to provide a first variant of the household appliance 1, in which the door 4 is hinged and assembled on the left side when viewed from the front, as in Figure 1 As shown through door 4. In this embodiment, the receiving sections 11, 12, 13, and 14 shown on the right end side 8b may not be provided. However, it is also possible that in one embodiment of the household appliance 1, not only are the receiving sections 11 to 14 formed on the right end side 8b, but also additional receiving sections 11 to 14 are formed on the left end side 8a in a mirror-symmetrical configuration with respect to the receiving sections about the intermediate axis M.

[0095] In another embodiment of a variation of the home appliance 1, it can be configured such that the appliance is only located on the right end side 8b. Figure 1 The receiving portions 11 to 14 are shown on the right side, and there are no corresponding left-side receiving portions 11 to 14 on the left end side 8a. Thus, in this embodiment, the door 4 can only hinge on the right side and swing about the rotation axis A formed on the right side.

[0096] In all three possible embodiments of the individual design schemes of the receiving parts 11 to 14 of the household appliance 1, the same hinges 5 and 7, which will be described later, can be used as the same components.

[0097] exist Figure 2 The central perspective view shows a household appliance 1 with a closed door 4. Exemplarily, a possible installation variation of door 4 is shown here, which can deflect about a vertical axis of rotation A on the left (when viewed from the front), or about a vertical axis of rotation A on the right, with hinges 5, 7, and in particular, the support angles arranged in a flip-symmetrical configuration. The corresponding deflectability is also indicated by symbolically shown arrows.

[0098] For clarity, Figure 2 The image shows the corresponding position of the lower hinge 5 in this exemplary embodiment, illustrating the possibility of this flip-symmetrical mounting. Regardless of whether the hinge 5 is mounted on the left or right side, in one embodiment, the spacing relative to the first end 9 or the second end 10 is the same when viewed along the width direction. Thus, as in... Figure 2 As shown, in the closed state, door 4 has the same position on housing 2 in both mounting variants.

[0099] Here, the middle M also represents the axis of symmetry oriented along the height direction, which is formed in the middle and the hinge 5 can be rotated and symmetrically mounted on it, depending on whether the door 4 with the left hinge or the door 4 with the right hinge should be realized.

[0100] exist Figure 3 A portion of the household appliance 1 is shown in a perspective view. This portion represents the lower right section of the housing 2 when viewed from the front. In the example shown here, the hinge 5 is mounted on the right end side 8b at the front.

[0101] The hinge is shown here in an assembled state. The hinge 5 has a support angle 15. The support angle 15 is constructed as a single piece. The support angle is specifically made of metal. For example, the support angle can be a metal plate angle. Furthermore, the hinge has a bushing 16. The bushing 16 is a component of the hinge 5 independent of the support angle 15. The bushing 16 is inserted into a support bolt of the support angle 15, which is not yet visible here. A cable 17 is also shown. The cable 17 of the household appliance 1 is laid on the hinge 5 in the area of ​​the hinge 5. One side of the cable 17 is... Figure 4It ends in the middle and ends in the other side in the housing 2.

[0102] exist Figure 4 The middle shows according to Figure 3 The arrangement is as shown, but the hinge 5 is shown in a detached state. Thus, the receiving parts 11 and 12 are visible on the right end side 8b.

[0103] In addition, an opening 18 is shown through which the cable 17 is routed into the housing.

[0104] As in Figure 5 As can be seen in the exploded view, the hinge has several separate parts. One aspect is the support angle 15. In this embodiment, the support angle 15 is designed as a U-shape. This support angle has a backing plate 19. This backing plate is configured to directly abut against the end sides 8a, 8b. Viewed along the width direction, the backing plate 19 has a first hole 20 and at least one opposing second hole 21. These two holes 20 and 21 are configured to guide fasteners, particularly bolts. Thus, the support angle 15, and therefore the entire hinge 5, can be screwed onto the front portion 6. In this embodiment, the two holes 20 and 21 are positioned at the same height when viewed along the height direction.

[0105] Furthermore, the support angle 15 has a bearing plate or coupling plate 22. This bearing plate or coupling plate extends horizontally. The bearing plate or coupling plate is arranged at an angle relative to the abutment plate 19, specifically 90°. Additionally, the support angle 15 has a support bolt 23. This support bolt 23 is spaced forward from the abutment plate 19 along the depth direction (z-direction). This support bolt extends away from the coupling plate 22 in the same direction as the abutment plate 19.

[0106] In addition, Figure 5 The support leg 24 is shown. The support leg 24 is separately constructed from the support angle 15. The household appliance 1 is placed directly on the ground using the support leg 24. The support leg 24 is designed for direct fastening to the support angle 15. In particular, the coupling plate 22 has a bolt receiving part 25 for this purpose. In this bolt receiving part, the support leg 24 can be screwed with a threaded pin 26 and can be set to adjust its height.

[0107] exist Figure 6 A perspective view shows one embodiment of the support angle 15. It can be seen that the support bolt 23 in one embodiment has an angular, particularly rectangular, cross-section. The coupling plate 22 has an embossed portion 27. This makes the coupling plate more rigid. The coupling plate 22 may also have threaded holes 28 and / or 29. An adapter, not shown here—which may be part of one embodiment of hinges 5, 7—is screwed onto the threaded hole 28 or threaded hole 29 depending on its mounting position on the support angle 15.

[0108] Such an external Figure 6As can be seen, the support angle 15 in the illustrated embodiment has a positioning element 30. The positioning element 30 extends further rearward in the depth direction (z-direction) than the abutment plate 19. This positioning element 30—which can fit into a receiving portion in the end side 8a or 8b—improves the reliable assembly of the support angle 15's position on the front part 6. In particular, this improves torsional resistance. The positioning element 30 is simply inserted into the receiving portion for this purpose.

[0109] There may also be more than one positioning element 30. See [reference needed] for details. Figure 7 Examples are shown in the text.

[0110] Two positioning elements, 30 and 31, are set here.

[0111] exist Figure 6 In one embodiment, the positioning element 30 can be produced from the sheet metal material of the support angle 15 itself by stamping and bending.

[0112] exist Figure 7 In one embodiment, the positioning elements 30 and 31 are separate pins that are pressed into the support angle 15, particularly the abutment plate 19.

[0113] In the illustrated embodiment, positioning elements 30 or 30 and 31 are configured below holes 20 and 21 when viewed along the height direction.

[0114] exist Figure 8 The diagram shows a front view of support angle 15 (viewed along the negative z-direction). In the case of projection—where the projection plane is the yx plane—support bolt 23 is positioned midway between holes 20 and 21. In this case, support angle 15 has an axis of symmetry M1 oriented along the height direction. In this case, holes 20 and 21 are specifically configured to be mirror-symmetrical about this axis of symmetry M1. Support bolt 23 is located on this axis of symmetry M1 and is also configured to be symmetrical about this axis M1. This also means that, in the projection plane, the intermediate axes M2 and M3 of holes 20 and 21, viewed along the width direction, have the same spacing as the axis of symmetry M1. Furthermore, it is set that in the projection plane, interval a2 is equal to interval a3. Interval a2 represents the distance measured along the width direction between the left boundary edge 23a of support bolt 23 and the intermediate axis M2 in the projection plane. Interval a3 represents the same horizontally measured interval between the right boundary edge 23b of support bolt 23 and the intermediate axis M3 of hole 21 in the projection plane. By utilizing the symmetry of the support angle 15, it is possible to achieve symmetrical mounting on the receiving parts 11 and 12, either on the left end side 8a or the right end side 8b, as specified. In particular, if the receiving parts 11 and 12 are as... Figure 1 The arrangement described above also achieves the flip-symmetrical installation, which should be understood as relating to the central axis M of the household appliance 1. This also applies in particular to the receiving units 13 and 14.

[0115] Such an external Figure 8 It is also evident that the support bolt 23, viewed along the width direction, is smaller than the interval between holes 20 and 21 measured along that width direction. This means that, in one embodiment, holes 20 and 21 are positioned directly next to the support bolt 23, both when viewed from the front and, in particular, when viewed in projection. This allows for the unimpeded guidance of bolts 32 and 33 along the depth direction (z-direction) next to the support bolt 23, and subsequently, the insertion of these bolts into holes 20 and 21. Furthermore, this geometry also allows for unimpeded assembly along the depth direction next to the support bolt 23 using tools such as a screwdriver, so that the bolts can be subsequently tightened.

[0116] Therefore, the width dimension of the support bolt 23 measured along the width direction is smaller than the interval between the hole shafts M2 and M3 measured along the width direction, and in particular smaller than the interval between the holes 20 and 21 measured between their mutually oriented hole edges.

[0117] exist Figure 9 As can be seen from the middle, according to Figure 3 and Figure 4 A partial front view, showing the hinge 5 mounted on the housing 2, particularly on the front 6. Symmetrical positions are visible here. Specifically, the support angle 15 is generally also set to define the rotation axis A of the door 4, which, when viewed along the width direction in the projected view—as shown in… Figure 8 As explained in the text, it is positioned in the middle between holes 20 and 21. Therefore, this projection surface can be located in the abutment plate 19 in the above embodiment.

[0118] Bolts 32 and 33 are shown. Bolts 32 and 33 are guided through holes 20 and 21 and screwed directly into receiving parts 12 and 11.

[0119] As described above, the hinge 5 has a cable guide 34. The cable guide 34 is configured to guide at least one cable 17 in the hinge 5 between the door 4 and the housing 2.

[0120] In particular, the cable guiding device 34 has a cable threading device 35 in the bushing 16, such as in Figure 10 As shown in the diagram. In this case, in Figure 10 The bushing 16 is shown from a perspective facing the bushing axis, extending parallel to the rotation axis A in the assembled state. Therefore, the bushing 16 has the cable threading device 35. This cable threading device 35 is specifically a cable channel.

[0121] Furthermore, bushing 16 has a insertion channel 36. The insertion channel 36 is separate from the cable threading device 35. The insertion channel 36 is configured to be inserted into the support pin 23. The support pin 23 is therefore configured to be inserted into the insertion channel 36.

[0122] The insertion channel 36 has an inner contour 37. The inner contour 37 has a clamping structure 38. In this embodiment, the clamping structure 38 has two clamping pins. The clamping structure 38 is used to clamp and retain the support bolt 23 within the insertion channel 36 as specified. The bushing 16 is torsionally mechanically coupled to the support bolt 23 when viewed in the direction of rotation about the axis of rotation A. (As shown in...) Figure 10 As can be seen, the cable threading device 35 and the plug-in channel 36 are two separate channels.

[0123] exist Figure 11 The image shows a side view of the lower portion of the household appliance 1. Specifically, it shows the arrangement according to... Figure 3 A side view of the arrangement. As can be seen here, the entire hinge 5, and in particular the entire support angle 15, extends before the front portion 6 and therefore also before the end side 8b, as shown here. The support angle 15 is simply fastened, in particular screwed, onto the end side 8b. The support angle extends forward in the depth direction from the end side 8b.

[0124] Furthermore, it can be seen that the support leg 24 is not directly mounted on the housing 2, but is only directly mounted on the hinge 5, especially the support angle 15.

[0125] The support leg 24 can be supported on the ground 44, such as the kitchen floor.

[0126] The coupling plate 22 has a first segment 22a and a second segment 22b offset from the first segment along the height direction y. The first segment 22a is located at a first height level H1. The second segment 22b is located at a second height level H2. Height level H1 is greater than height level H2. Height levels H1 and H2 are each measured through the substantially planar upper surfaces of 22a and 22b. A molded support bolt 23 is adjacent to the first segment 22a. A threaded hole for receiving a support leg 24 is constructed in the second segment 22b. Figure 11 In the view, the leg 24 is not screwed in until it reaches the stop in the support angle 15. However, if the leg 24 is continued to be screwed in until it stops at the support angle 15, then the leg 24 can be prevented from colliding with the lower edge (of the door, not shown) by the deeper second section 22b. Figure 12 The perspective view of the hinge 5, including the leg 24, is shown again, as explained so far.

[0127] exist Figure 13An exploded view of another embodiment of hinge 5 is shown in the figure. Unlike the embodiments described so far, in this hinge 5, the bushing 16 is configured to be smaller when viewed in the height direction. Furthermore, this embodiment of the hinge includes an additional adapter 39. The adapter 39 is separate from the bushing 16 and separate from the support angle 5. This embodiment of hinge 5 is configured to have a closing function. In contrast, according to... Figure 3 , 4 The embodiments 5, 9, 11 and 12 are configured to not have this shut-off function.

[0128] Adapter 39 has a plug-in channel 40, such as in Figure 15 As shown in the perspective view. The insertion channel 40 is configured to mate with the support bolt 23 or allow the support bolt to extend through it. In particular, the insertion channel 40 is also configured to achieve clamping and fixing between the adapter 39 and the support bolt 23. Moreover, the adapter 39 is torsionally mounted on the support angle 15. In particular, the adapter is torsionally mounted on the support bolt 23.

[0129] For example, for Figure 6 and 7 As already explained, the support angle 15 may have threaded holes 28 and 29. Depending on the mounting position of the adapter 39 on the support angle 15, the adapter 39 can be used with bolt 41 ( Figure 13 It is screwed onto the threaded hole. The bolt 41 is guided through the hole 42 in the adapter 39.

[0130] In this embodiment, the adapter 23 may also be configured to have a recess 43 that opens on the edge side. This recess is configured to allow the cable 17 to be routed therein. Even so, in this embodiment, it is not necessary to guide the cable 17 through or through a specific hole that is surrounded or closed on the peripheral side.

[0131] Adapter 39 can also be flipped and mounted on support angle 15. From Figure 15 Starting from the position shown, the adapter can be inserted into the support bolt 23, and the holes 42 and 29 can be aligned, subsequently forming a corresponding threaded connection. However, the adapter 39 can also be inserted from... Figure 15 The view is rotated 180° from the center, so that the support pin 23 is then inserted through the insertion channel 40 and the hole 42 is aligned with the hole 39. In this respect, a corresponding screw connection can also be achieved.

[0132] exist Figure 14 The diagram shows a perspective cross-sectional view of the bushing 16. It is evident that the upper and / or lower edges of the cable threading device 35 are rounded. This prevents damage to the threaded cable.
