Definitions

  • the invention relates to a door locking device for electrical devices, in particular for washing machines, of the type mentioned in the preamble of claim 1.
  • Such devices are known, inter alia, from DE-3 214 436 (EP-A-0 092 162). They are bimetallic devices with the property of locking the door of an electrical device with a delay as well as unlocking it with a delay. Simultaneous water level monitoring when using these conventional door locking devices, for example in washing machines, is not provided.
  • the invention has for its object to provide a door locking device for electrical appliances, especially for washing machines, which ensures immediate locking and a delayed unlocking of the appliance door with simultaneous water level monitoring. This object is achieved in accordance with the characterizing features of claim 1.
  • a contact spring engages in the latching recess of the locking slide which is parallel to its passage openings and which forms a signal contact together with a fixed contact piece located opposite one another.
  • this contact spring disengages from the latching recess and closes the signal contact due to its spatial displacement.
  • current flows through the coil of an electromagnetic locking relay directly or via a program control, whereby the locking arm of the magnet armature lever is attracted.
  • a locking plunger is mounted which, through the movement of the magnet armature lever, engages through a passage opening in the locking slide to prevent movement. This ensures that the door locking device according to the invention is locked without delay.
  • the second contact arm of the magnet armature lever - hereinafter referred to as the main contact arm - is a bearing for a connecting piece which completely fills the through opening of a pressure chamber and is thereby guided in a longitudinally displaceable manner and is fastened to a membrane which divides the pressure chamber volume.
  • the diaphragm-side end of the connecting piece increasingly acts on a contact spring against its spring force.
  • the contact spring forms the main contact point, which can thus be closed by the locking movement and consequently also switches on the electrical device virtually without delay.
  • the membrane attached to the opposite side of the connecting piece divides the pressure chamber, which is connected to a pressure compensation chamber via a passage channel.
  • the pressure compensation chamber has a connection channel leading to the outside, whereby it e.g. can be filled with water. Due to this design, the door locking device ensures a delayed unlocking with water level monitoring. If the electrical device is switched off, the locking relay no longer pulls the armature lever. The restoring force of the main contact spring causes the unlocking movement, which is, however, delayed by the counterpressure on the membrane which forms in the pressure chamber. The delay time can be determined using the special design of the membrane and pressure chamber system. In this way, for example, the drum outlet on a washing machine can be protected against premature external access. Due to the design of the pressure chamber system according to the characterizing feature of claim 1, water level monitoring is also possible, for example in a washing machine, spin dryer, dishwasher or the like.
  • the lever-side space of the pressure chamber is filled with water via the passage channel, the pressure compensation chamber and the connection channel. Since a liquid in a pressure chamber develops a significantly higher back pressure than a gas, the door locking device can only be unlocked very slowly or not at all. As a result, the door of the electrical device can only be opened when the water level has fallen below a certain level and the pressure chamber has been emptied via the passage channel, pressure compensation chamber and outlet channel. The emptying time can be determined via the length and cross-sectional area of the passage. This configuration of the door locking device prevents water from leaking out of washing machines, for example, by opening the appliance door prematurely.
  • the pressure spring which acts increasingly on the main contact arm of the magnet armature lever during the locking process in accordance with the characterizing feature of claim 6 supports the restoring force of the contact spring. Due to the adjustment possibility of this compression spring described in the characterizing feature of claim 7, a simple adjustment of the restoring force and thus the desired delay time for the unlocking is possible.
  • the door locking device can thus be easily and quickly adapted to the conditions required for the practical use of the electrical device.
  • the stiffening plates described in the characterizing feature of claim 8 ensure that the membrane is securely fastened to the connecting piece. In addition, the membrane is inherently more stable and its damage due to tearing or bursting is avoided.
  • claim 10 enable the door locking device to be used both for doors with "left-hand” and doors with “right-closing” door locking hooks.
  • the door locking device for electrical appliances contains a locking slide 3 which is mounted in a longitudinally displaceable manner in a guide groove 1 in the housing 2 and which is provided with a plurality of passage openings and a latching recess 4, the boundary surfaces of which form an obtuse angle to one another.
  • the door locking hook 6 passes through a passage opening as the closing opening 5 according to FIG. 2, which blocks the appliance door by engaging behind the housing wall 2.
  • the locking plunger 8 passes through one of the two locking openings 9 to prevent movement.
  • an extension of the guide groove 1 forming a free space 1 ' is provided behind the locking slide 3 in the open position of the device, the length of the free space being at least half Distance of the centers of the passage openings corresponds.
  • the locking openings 9 lie on both sides of the guide groove 10 receiving the locking plunger 8.
  • the guide groove 10 for the locking plunger 8 has an extension 11. In the open position (FIG. 1) of the door locking device, the L-shaped free end 12 of the contact spring 13 engages in the latching recess 4. This forms the signal contact 15 together with the parallel opposing fixed contact piece 14.
  • the L-shaped contact spring free end 12 whose horizontal leg resembles a negative of the shape of the latching recess 4, disengages from the latching recess 4, thereby becoming in the direction of Fixed contact piece 14 against the restoring force of the contact spring 13, whereby the signal contact 15 can be closed (Fig. 2).
  • This signal contact controls a locking relay 16 located to the side of locking slide 3, which is composed of magnetic yoke 17, coil 18, core 19 and double-armature armature lever 20.
  • This magnet armature lever 20 is located laterally next to the pole face 21 of the magnet and consists of a locking arm 22 and a main contact arm 23.
  • the free end of the locking arm 22 passes through the locking plunger 8, which is displaced along the guide groove 10 by the pivoting movement of the magnet armature lever 20 during locking.
  • the free end of the main contact arm 23 is a bearing for the connecting piece 24, which passes through the passage opening 25 of the pressure chamber cover 26 and is thereby longitudinally displaceable.
  • the end of the connecting piece 24 lying in the pressure chamber is fastened via stiffening plates 27 to a membrane 28 which divides the pressure chamber 29 into two volumes.
  • This pressure chamber is connected to the washing drum space via a passage channel 30, a pressure compensation chamber 31 and a connection channel 32, for example in a washing machine. As explained in the description, this makes it possible to monitor the water level in electrical appliances in which water is used.
  • the end of the connecting piece 24 on the diaphragm side increasingly applies a contact spring 33 during the locking, which together with a fixed contact piece 34 located opposite one another forms the main contact point 35.
  • the contact spring 33 In the locked position (FIG. 2), the contact spring 33 is spatially displaced by the action and the main contact point 35 is closed. The connected electrical device is then put into operation.
  • the magnet armature lever 20 is rotatably mounted on the housing part 36, which comprises the magnet coil 18 on the side opposite the locking plunger 8. Together with the obtuse angle 37, which form the locking arm 22 and the main contact arm 23 to one another, this arrangement provides sufficient working paths for locking pushes I8 and connecting piece 24, as well as a clean magnetic connection between the magnetic yoke 17, core 19 and magnetic armature lever 20 (FIG. 2 ).
  • the main contact arm 23 of the magnet armature lever 20 is acted upon on the side opposite the locking relay 16 by a compression spring 38 which is placed on an adjusting screw 39 inserted in a housing part 40.
