  • a door In household appliances, such as washing machines, a door is locked in the locked state by mechanical positive locking.
  • the doors are equipped with hooks or eyes that are inserted into the interior of the lock when they are closed.
  • Some household appliances have a mechanical opening button to open the door.
  • the publication EP 0 109 590 B1 describes a security door lock in which all components of the security device and for opening and closing the door are combined in one housing, so that only one component is required for these functions.
  • Two limit position sensors and a solenoid of the electromechanical locking device are combined in one housing to form a single unit.
  • the patent US 2,888,290 shows a refrigerator comprising a magnetic lock.
  • the disclosure WO 00/11296 A1 shows a housing of a refrigerator, the housing having a locking device comprising an electromagnet.
  • the disclosure EP 2 284 340 A2 shows a magnetic catch for closing an opening.
  • EP 2 045 423 A2 shows a device for releasable locking of relatively movable parts.
  • the disclosure US 2006/14545 A1 discloses a dishwasher comprising a housing and a door.
  • a magnetic locking device is provided to magnetically hold the door closed on the housing.
  • the object is achieved by a household appliance in which the household appliance comprises a locking device with at least one permanent magnet for exerting a holding force for locking the door and a coil for generating a counter magnetic field for releasing the holding force.
  • the locking device on the one hand enables the door to be opened from the inside and on the other hand releases the door via a door opening button.
  • the door of the household appliances is kept closed by means of a holding force, which is realized by force-locking.
  • the non-positive lock provides holding forces in two stages. A lower holding force for locking the door and an increased holding force that prevents the door from being opened non-violently, i.e. locking
  • a household appliance is understood to be a device that is used for household management.
  • This can be a large household appliance, such as a washing machine, a tumble dryer, a dishwasher, a cooking appliance, an extractor hood or a household appliance, such as e.g. a refrigerator, freezer or fridge-freezer.
  • this can also be a small household appliance, such as a water heater, a fully automatic coffee machine, a food processor or a vacuum cleaner.
  • the locking device is arranged in the door or a housing of the household appliance. This has the technical advantage, for example, that the holding force can be transmitted efficiently.
  • the door or the housing of the household appliance completely or partially comprises a magnetically highly permeable material for coupling with the generated magnetic field.
  • the magnetically conductive material for example, achieves the technical advantage that the holding force of the door or the housing is generated.

  • the spring element 115 is implemented, for example, by a helical compression spring or an elastic door seal.
  • the holding force of the door is generated by magnetic force.
  • Different locking forces in the unlocked and locked state are realized when opening, locking or unlocking by changing the magnetic field by means of the electrical coils 107 and / or an iron core or magnet shift by the control armature 111.
  • low locking forces can be achieved in the unlocked state, ie operating forces less than 50 N and high locking forces of, for example, 200 N in the locked state.
  • the part on the door side must be made of a highly permeable material.
  • FIG. 2A shows the closure device 103 in the currentless state of the coil 107.
  • the door 101 is opened a gap and is held by the elastic element 115 at a distance from the closure device 103.
  • the control armature 111 is pressed against the flux guide pieces 109-1 and 109-2 by the magnetic field of the permanent magnets 105-1 and 105-2, so that the magnetic field is directed into the area of the control armature 111.
  • Figure 2B shows the closure device 103 in a de-energized state of the coil 107 after the door 101 has been pressed and closed manually.

  • the control armature 111 is then pressed outwards by the spring element 113.
  • the magnetic field in the area of the locking anchor 117 is thereby strengthened, so that the holding force between the locking device 103 and the locking anchor 117 increases and the door 101 is locked.
  • the holding force on the door 101 in this state is, for example, 280 N. After that, the current through the coil 107 is interrupted.
  • Figure 2D shows the closure device 103 in the currentless state of the coil 107.
  • the control armature 111 is held by the elastic element 113 at a distance from the ferromagnetic flux guide pieces 109-1 and 109-2, so that this is from the two permanent magnets 105-1 and 105- 2 generated magnetic field shifted to the right side in the direction of the locking anchor 117.
  • the spring element 113 creates an air gap between the control armature 111 and the flow guide pieces 109-1 and 109-2. As a result, the increased holding force can be maintained even when the closure device 103 is in the currentless state, so that the door 101 remains locked.
  • Figure 2E shows the closure device 103 in a more positively energized state of the coil 107 after the initiation of an opening phase for unlocking and opening the door 101.
  • the air gap between the control armature 111 and the flow guide pieces 109-1 and 109-2 is first closed. This is initiated by the coil 107 being briefly energized for a short time.
  • the magnetic field thus generated by the coil 107 amplifies the magnetic field that is generated by the permanent magnets 105-1 and 105-2.
  • the field lines on the left side of the flow guide pieces 109-1 and 109-2 interact with the control anchor 111.
  • the force exerted on the control armature 111 exceeds the force of the spring element 113, so that the control armature 111 is again attracted to the flow guide pieces 109-1 and 109-2.
  • the holding force on the door 111 is hereby increased again briefly.
  • Figure 2F shows the closure device 103 in the more positively energized state of the coil 107 with the control armature 111 applied. Both the control armature 111 and the closure armature 117 are held on the flux guide pieces 109-1 and 109-2.
  • Figure 2G shows the closure device 103 in a currentless state of the coil 107 with the control armature 111 applied. This state corresponds to the state from Figure 2B which results shortly after the door 101 is closed.
