Definitions

  • the invention relates to a door hinge for a household appliance according to the preamble of claim 1. Furthermore, the invention relates to a household appliance according to the preamble of claim 30.
  • a door hinge in which a free hinge part is fixed in the door and another hinge part, a sliding part and a spring are fixed in or on the housing of the household appliance.
  • the sliding part is pivotally mounted on the free hinge part and coupled via the spring to the housing of the household appliance.
  • the sliding part on the hinge part which is fixed to the housing of the household appliance, by means of a roller along a predetermined. Track movably mounted. In this way, each pivot position of the door is assigned a specific position of the sliding part. As a result, a torque acts on the pivot axis of the door, which depends on the pivoting position of the door.
  • the known door hinge has the disadvantage that the assembly on the household appliance is relatively expensive. The two hinge parts and the spring must be attached to the household appliance. In addition, the effort is relatively high to adjust the home appliance and the door hinge to each other.
  • the invention is therefore based on the object to provide a door hinge for a household appliance that is easily mounted in or on the home appliance and compatible with as many different household appliances.
  • the first hinge part, the displacement part and the spring form a structural unit, wherein the displacement part is coupled via the spring with the first hinge part.
  • the essence of the invention is that the sliding part and the spring are an integral part of the first hinge part.
  • the sliding part is coupled via the spring with the first hinge part.
  • To install the door hinge on the household appliance it is sufficient to mount the first hinge part to the housing of the household appliance. It is not necessary to attach the sliding part and / or the spring in addition to the housing of the household appliance. There are no special designs on the household appliance required to mount the door hinge.
  • the door hinge according to the invention can be attached to numerous household appliances.
  • the displacement part is pivotable on the second hinge part about a further pivot axis.
  • This is a structurally simple method to couple the sliding part and the second hinge part with each other.
  • the sliding member is substantially linearly movable relative to the first hinge member between the first and second positions. This also contributes to a low design effort for the door hinge.
  • the displacement part can be arranged substantially within the first hinge part.
  • the first hinge part comprises a hinge housing, in which the displacement part is arranged.
  • the hinge housing significantly contributes to the compact design of the door hinge.
  • the at least one spring is in a relaxed state at the minimum pivot angle. Since many household appliances, the door is usually closed, thereby the wear of the springs, and thus the door hinge is kept low.
  • the at least one spring is in a tensioned state at the maximum pivoting angle.
  • the at least one spring may be formed as a compression spring and / or tension spring.
  • the at least one spring is coupled to a rocker and / or a roller. Thereby the torque can be adjusted depending on the swivel angle.
  • the roller is rotatably mounted on the rocker. This increases the setting options for the torque.
  • the torque also depends on the diameter of the roller and the length of the rocker.
  • the rocker is preferably pivotally mounted on the spring.
  • the door hinge comprises a barrier, which is provided for interaction with the rocker and / or the roller. This provides an additional option for adjusting the torque.
  • the barrier is arranged in the hinge housing. This also contributes to the compact design of the door hinge.
  • the barrier at the minimum pivot angle supports the roller so that increased force is required to overcome the minimum pivot angle. In this way, a closing pressure is generated, which ensures the secure closing of the door.
  • the barrier can have at least one convex surface section, which is formed in sections complementary to the surface of the roller.
  • the convex surface portion allows a stable position of the door hinge, in particular between the minimum and maximum swing angle.
  • the sliding member is coupled to the first hinge part via at least one slotted guide or the like.
  • the slotted guide a guide pin and a recess, wherein the recess are arranged in a side wall of the hinge housing and the guide pin in a side wall of the sliding part.
  • the guide pin can be attached to the side wall of the sliding part, preferably screwed.
  • the screw-on guide pin facilitates the assembly of the door hinge.
  • pivot axis and the further pivot axis are preferably slightly spaced from each other. This also contributes significantly to the compact design of the door hinge.
  • the first hinge part may have a locking device to block the movement of the sliding part.
  • the locking device is pivotally mounted on the hinge housing and can be brought by a pivoting movement with the sliding part in engagement.
  • the door hinge is locked by the locking means at the minimum pivot angle.
  • the door can be locked in the closed state, which is advantageous for example in a cooking appliance during a pyrolysis cleaning or in a washing machine during the spin operation.
  • the first hinge part may have a securing device to block the movement of the sliding part, wherein the securing means is movably mounted on the hinge housing.
  • the securing device by means by a displacement with the sliding part are brought into engagement.
  • the safety device can be operated manually.
  • the door hinge is preferably blocked at the minimum pivot angle.
