[0121] To be able to keep the door 104 secured in the closed state, for instance, magnetic locking parts 102 may be used to interact with ferromagnetic parts 103 to form a magnetic connection. In each case, one of these components is attached to the front panel of the washing machine 100, and the other component is attached to the door 104. The magnetic connection not only ensures that the door 104 does not open unintentionally, but also prevents the door 104 from swinging relative to the front panel 100 of the washing machine during operation of the washing machine.
[0122]
[0123] The first hinge part 10 has two spaced-apart walls 14. Hinge pin mounts 15 and 16 are incorporated into the walls 14. The hinge pin mounts 15 in the walls 14 are interaligned. Furthermore, the hinge pin mounts 16 in the walls 14 are also interaligned.
[0124] A second hinge part 40 can be coupled to the first hinge part 10 via a four-bar linkage system in an articulated manner. In this case, the four-bar linkage system has two hinge levers, an outer hinge lever 20 and an inner hinge lever 30.
[0125] The outer hinge lever 20 has two spaced-apart wall elements 22, which are interconnected by a bridge 21. Each of the wall elements 22 has two knuckles 23, 24. The knuckles 23 are interaligned; just like the knuckles 24. The two wall elements 22 of the outer hinge lever 20 can be set in the area of the first hinge part 10 formed between the two walls 14. Preferably, the outer sides of the wall elements 22 are guided on the insides of the walls 14 facing each other. The knuckles 23 are aligned with the hinge pin mounts 15, thus a first hinge axis 17, which may have the form of a pin, may be inserted through the aligned hinge pin mounts 15 and the knuckles 23 to provide a swivel coupling of the outer hinge lever 20 to the first hinge part 10.
[0126] The inner hinge lever 30 has a lever arm 31 to which an end eye 32 may be directly connected.
[0127] The inner hinge lever 30 supports two spaced-apart bearing sections 33. Interaligned knuckles 34 may be provided on these bearing sections 33.
[0128] As
[0129] To assemble the inner hinge lever 30, the end eye 32 is placed in alignment with the hinge pin mounts 16 of the first hinge part 10 and placed between the walls 14. Then, a second hinge axis 18 extending through the hinge pin mounts 16 and the end eye 32 can be used to achieve an articulated coupling of the inner hinge lever 30 to the first hinge part 10.
[0130] The second hinge part 40 has a mounting section 41, as further shown in
[0131] At the end facing away from the retaining element 41.1, the mounting section 41 merges into a transition section 42.
[0132] The second hinge part 40 is provided with walls on its two longitudinal sides. These two walls are spaced apart, and preferably extend in parallel to each other. The two walls can form sliding pieces 43 on the outer sides facing away from each other.
[0133] The two walls are each provided with a first locating mount 44.1. The first two locating mounts 44.1 are interaligned. Further, a second locating mount 45 may be provided in each of the walls, wherein the second locating mounts 45 are interaligned. Furthermore, hinge pin mounts 45.2 and hinge pin mounts 45.3 may be provided in the two walls. The hinge pin mounts 45.2 and the hinge pin mounts 45.3 are interaligned.
[0134] The second hinge part 45 is provided with a lug 46 on its rear end. This lug 46 is located between the two sliding pieces 43.
[0135] To couple the outer hinge lever 20 to the second hinge part 40 in a swiveling manner, the outer hinge lever 20 is placed between the two longitudinal walls of the second hinge part 40. In this case, the wall elements 22 then face the insides of the walls of the second hinge part 40. The knuckles 24 are aligned with the hinge pin mounts 45.3. In that way, a joint axle 29 can be inserted through the aligned hinge pin mounts 45.3 and the knuckles 24 to form a hinge joint.
[0136] The inner hinge lever 30 is also connected to the second hinge part 40 in a similar manner. The inner hinge lever 30 is placed between the two walls of the second hinge part 40, such that the outer sides of the bearing sections 33 face the insides of the walls. Then the knuckles 34 are aligned with the hinge pin mounts 45.2. A joint axle 36 extending through the aligned knuckles 34 and the hinge pin mounts 45.2 can be used to establish the hinge connection.
[0137] As
[0138] The spring 25 has a spring element 27 to which two spring arms 26, 28 are attached. The spring arms 26, 28 can be moved relative to each other against the force of the spring element 27. The spring arm 28 is arranged and formed such that it is rests on the end of the first joint axle 17. The second spring arm 26 is designed and arranged to be supported relative to a locating element 45.1. This can be clearly seen in figures
[0139] The locating element 45.1 can advantageously be designed as a bolt, which extends through the two aligned second locating mounts 45.
[0140] Advantageously, the spring 25 is formed from a section of wire, wherein the spring element 27 is wound as a spiral spring. As can be seen from
[0141] A damper unit can optionally be connected to the hinge 10. The damper unit comprises a damper 50, which is designed as a fluid linear damper. This damper 50 has a damper housing 52. A piston can be displaced against the pressure of a fluid, for instance air or a liquid, in particular oil, in the damper housing 52. A piston rod 51 is connected to the piston. The piston rod 51 bears an actuating piece 53. The actuating piece 53 can be integrally formed by the piston rod 51 or can be placed on the piston rod 51 as a separate component.
[0142] The damper unit comprises a carriage 60. The carriage 60 has a base part 61 having a damper mount 62. The base part 61 has guides 63 on its two longitudinal sides. They can be formed by the lateral wall elements of the base part 61.
[0143] On its underside, the carriage 60 is equipped with a slideway 64. The slideway 64 may have the form of a recess recessed from the base part 61. As
[0144] The damper unit may be connected to the second hinge part 40. For this purpose, the damper 50 is inserted into the damper mount 62 of the carriage 60. The damper housing 52 rests on the rear of a stop surface of the damper mount 62 in the direction of the longitudinal extension of the piston rod 51 in a form-fitting manner.
[0145] The unit thus formed can be inserted into the second hinge part 40 from below. This is shown in particular in
[0146] Within the damper 50, there is a spring that acts on the piston to hold it in the extended position and thus to hold the piston rod 51 in the extended position shown in
[0147] To locate the damper unit, the damper housing 52 is held on the locating element 45.1. This locating element 45.1 is preferably the same locating element 45.1 that supports the spring arm 26 as well. Further, the damper housing 52 rests against the underside of the mounting section 41. The locating element 44.1 is used to prevent the damper unit from falling downwards out of the second hinge part 40. This locating element 44.1 extends through the interaligned first locating mounts 44. In the assembled state, the locating element 44.1 forms a guide arrangement in conjunction with the slideway 64. This guide arrangement allows the carriage 60 and with the carriage 60 the damper housing 52, to be moved linearly in the direction of the longitudinal extension of the piston rod 51. When the carriage 60 is displaced, the base part 61 slides on the first locating element 44.1. Furthermore, the damper housing 52 slides along the locating element 45.1 and finally the damper housing 52 also slides along the underside of the mounting section 41. In particular, the guide can be designed to provide a small guide play between the guide partners mentioned.

[0151] In particular, the rear surface may define or form a planar mounting section. This mounting section can be used to place the base part 70 against a surface of the cabinet box or machine body. The mounting section 71 is penetrated by attachment mounts 72. As shown here, the attachment mounts 72 can advantageously be formed as elongated holes. The longitudinal axes of the two slotted holes 72 extend in the direction of a first adjustment direction.
[0152] The base part 70 has a retaining mount 77. The retaining mount 77 penetrates the base part 70 from the front to the rear.
[0153] On its longitudinal sides the retaining mount 77 may be delimited by guides 76.1. In that case, the guides 76.1 form guide surfaces facing the retaining mount 77.
[0154] A clamping section 44 is provided in the one end area of the base part 70 facing the guides 76.1. A mounting section 75 may be integrally formed on the clamping section 74. Advantageously, the mounting section 75 has a screw mount. Preferably, the thread axis of this screw mount can be perpendicular to the upper clamping surface formed by the clamping section 74. Opposite the clamping section 74, the base part 70 has a connection piece 73. This connection piece 73 engages over a guide section 76.2 of the guide 76.1. Further guide surfaces may be provided on the guide section 76.2. The further guide surfaces are aligned with the guide surfaces assigned to the clamping piece 74.
[0155] The retaining mount 77 is delimited by the two guides 76.1, the clamping section 74 and the connection piece 73.
[0156] Below, the function of the hinge described above is explained with reference to

[0163] As
[0164] The second hinge part 40 has a lug 46 for mounting the damper 50. The damper 50 is again of the same design as the damper 50 according to the first exemplary embodiment. The lug 46 is formed like a pocket. It has two spaced-apart wall sections 46.1. At their longitudinal end, the two wall pieces 46.1 are connected to the counter bearing 47.
[0165] As
[0166] The piston rod 51 rests against the counter bearing 47 of the second hinge part 40.
[0167] In the open hinge position, shown in
[0168]
[0169]
[0170] The wall elements, which preferably form the sliding pieces 43, extend beyond the retaining element 41.1 and join the guide element 48 on both sides. Third interaligned locating mounts 48.1 are inserted into these walls below the guide element 48. A locating element 48.2 can be inserted through these third locating mounts 48.1.
[0171]
[0172] A connector 80 is located between the two spaced-apart coupling pieces 67. The connector 80 has two spaced-apart holders 81, which are interconnected by an integrally molded-on connection part. The interaligned drilled holes 82, the interaligned drilled holes 83 and/or the interaligned penetrations 84 are machined into the two holders 81.
[0173] As
[0174] The connector 80 provides the connection between the inner hinge lever 30 and the carriage 60.
[0175] The bearing axle 35.2 is used to couple the inner hinge lever 30 coupled to the connector 80. This bearing axle 35.2 is inserted through the interaligned bearing mounts 35.1 of the inner hinge lever 30 and the also interaligned drilled holes 82 of the connector 80, which are designed as elongated holes.
[0176] The locating element 48.2 is used for coupling the carriage 60. The locating element 48.2 is guided through the interaligned mounts 68 of the carriage 60 and the penetrations 84, which are also aligned therewith and which are formed as elongated holes and which are provided on the connector 80.
[0177] The assignment and coupling of the inner hinge lever 30, the connector 80 and the carriage 60 can be clearly seen in
[0178] The function of the hinge can be seen in more detail in
[0179]
[0180]
[0181] To guide the linear motion of the carriage 60, the outer contour of the base part 61 slides within the inner contour of the guide element 48 and/or the guides 63 slide on assigned linear guide surfaces of the second hinge part 40. During a displacement, the damper housing 52 also slides along the locating element 44.1.
[0182] Once the hinges described above have been installed and the door 104 has been hinged in that way, the hinge can be adjusted to align the position of the door 104.
[0183] In the horizontal direction, the door is then aligned in a simple manner by loosening the clamping bolt 78. Then, the second hinge part 40 can be moved linearly with respect to the base part 70. Once the desired adjustment position has been reached, the clamping bolt 78 can be set again.
[0184] The base part 70 is used for adjustments in the vertical direction. The fastening screws, which were screwed into the locating mounts 72 of the mounting section 71, can be loosened for this purpose. Then the base part can be adjusted vertically with respect to the machine or cabinet box. Once the desired position has been reached, the fastening screws can be re-tightened.
