Definitions

  • the invention relates to a door locking device with the features mentioned in the preamble of claim 1.
  • the invention has for its object to provide a door locking device of the type mentioned so that it is simple, but definitely adjustable and ready to install. This object is achieved by the characterizing features of claim 1.
  • the lock plate When the lock plate is arranged between a lock plate housing wall and a side wall of the locking device, the lock experiences plate through both walls additionally a guide, if necessary, by direct abutment on these walls or by abutment on projecting projections from the walls.
  • the solution according to the characterizing feature of claim 2 is particularly advantageous.
  • the characterizing feature of claim 3 in particular in the embodiment of the characterizing feature of claim 4, provides drip protection of the locking device without requiring an additional sealing of the parting line between the outer wall of the locking device and the lock plate housing walls.
  • the lock plate takes a predetermined displacement position within the lock plate housing. These are a middle position in which the door locking hook for closing and opening the door of the electrical device can be passed unhindered through the locking opening of the lock plate, as well as a locking position of the lock plate on both sides of this middle position, in which a recess in the lock plate overlaps with the locking slide of the locking device, which, after switching on the device current, dips into the lock plate recess due to the deflection of a bimetal arranged in the locking device and thus blocks its longitudinal displacement.
  • a structurally particularly advantageous embodiment of the spring catch is set out in the characterizing features of claim 6.
  • the characterizing feature of claim 7 ensures a particularly exact positioning of the lock plate either in its open position or in one of its two locking positions, which in the locking position also ensures an exact overlap of the locking slide with the lock plate recess.
  • a separate return spring acting on the lock plate - as in the prior art described at the outset - is not required.
  • the essential movement of the lock plate from its opening to the locking position is effected solely by the door locking hook, while its fine positioning in one of the two functional positions is carried out by the spring lock or locks if necessary.
  • the characterizing features of claim 8 relate to a particularly simple and effective design of the spring catch between the lock plate and lock plate housing.
  • the functional parts of the locking device between its bottom and the circuit board are arranged protected against mechanical influences from the outside, the outer wall of the locking device also providing protection against lateral engagement in the space between these two covers.
  • the characteristic of claim 10 serves to ensure the exact positioning of the locking device in the inserted position within the lock plate housing together with the locking means.
  • the locking means keep the locking device only in the inserted position, while the other positioning of the locking device within the lock plate housing is ensured by the drawer-like guide means.
  • the entire door locking device can be attached to electrical appliances in a simple manner.
  • the door locking device is also used for locking locks and covers, but especially for washing machine doors. It is intended to ensure that the electrical device can only be put into operation if the door lock is in accordance with regulations. The door is kept locked for the duration of operation. It is therefore not possible to open the door while the electrical device is switched on.
  • the door locking device contains a lock plate 1, which is mounted within the lock plate housing 2 in the direction of arrow 3 to be longitudinally displaceable.
  • the longitudinal displacement movement of the cam plate 1 is not represented by a, by cross with the connected to be locked door, the p batten end the lock 4 is arranged closing the opening 5 door closing hook can be controlled, as described in principle in DE-OS 27 08 088th
  • the door locking device contains a locking device 6, which has a locking slide 8 which can be inserted in a locking manner in one of the two locking plate recesses 7 in the locking position of the locking plate.
  • a locking device 6 which has a locking slide 8 which can be inserted in a locking manner in one of the two locking plate recesses 7 in the locking position of the locking plate.
  • the insertion movement of the locking slide 8 is controlled by the inrush current of the electrical device, as will be explained in more detail below.
  • the lock plate 1 is guided outside the sliding area of the lock opening 5 of the lock plate 1 in a lock plate housing 2 which is only open to one side (opening 9).
  • the locking device 6 can be inserted like a drawer into the opening 9 of the housing 1 and locked there in the insertion position.
  • the outer wall 10 of the locking device 6 has on its upper and lower side locking projections 11 which, in the inserted end position, engage in locking recesses 12 which are introduced into the corresponding side walls of the lock plate housing 2.
  • the locking slide 8 is aligned with one of the lock plate recesses 7.
  • the bottom plate 13 is provided on its sides with a guide rib 14 or a guide groove, which with corresponding , on the inside of the housing side walls 15, 16 integrally formed guide ribs 17 or a guide groove 18.
  • the lock plate 1 lies between the lock plate housing wall 19 forming the housing base and the base plate 13 of the locking device 6.
  • the power connections of the locking device 6, which are preferably designed as flat plugs 20-22, are led out of the outer wall 10 closing the open side (opening 9) of the lock plate housing 2 in the inserted position.
  • the locking device 6 faces the lock plate 1 with its bottom plate 13 penetrated by the locking slide 8 and is aligned parallel to the lock plate level.
  • the open side (opening 9) of the lock plate housing 2 extends approximately at right angles to the lock plate level and points in one construction position down.
  • This drip water protection is particularly effective when the outer wall 10 of the locking device 6 is inserted into the opening 9 of the lock plate housing 2 or is sunk therein.
  • the outer flanks 24, 25 of the lock plate end 23 on the housing side are part of one leg 26 and 27, respectively.
  • the two flanks 24,25 are each provided with three Rastaus- principleun g en 28-30, each of which interacts with an integrally injection-molded with the plastic lock plate made of casing 2 housing projection 31 and 32 respectively.
  • the housing projections 31, 32 protrude from the lock plate housing wall 19 which runs parallel to the lock plate 1. Their shape is a negative for the acute-angled, opposite recesses 28-30.
  • the lock plate 1 With the housing projections 31 and 32 lying in the mutually opposite latching recesses 29, the lock plate 1 is in its open position, in which the door locking hook can be actuated without hindrance, ie it can be inserted and executed in the locking opening 5 (FIG. 3). If a door locking hook which closes to the left is used for the door closure and is transferred to its door closing position, the lock plate 1 is shifted to the left in the direction of the arrow 3.
  • the U-legs 26, 27 of the lock plate 1 spring inwards.
  • the housing jumps 31, 32 slide out of the locking recesses 29 and fall into the locking recesses 28.
  • the spreading pressure of the U-legs 26, 27 ensures that the housing projections 31, 32 lie snugly in the latching recesses 28, so that in each case the lock plate 1 assumes a position in which its right lock plate recess 7 is in the overlapping position with the locking slide 8 of the locking device is.
  • the housing projections 31, 32 fall into the latching recesses 30 of the lock plate 1 and thereby automatically bring the left lock plate recess 7 into overlapping position with the locking slide 8.
  • the individual parts of the control mechanism for the locking slide 8 are clearly shown in particular in FIG. 7.
  • the components of the controller are alsmon on the sprayed plastic base plate 13 - advantage.
  • the bimetallic connector 38 is inserted with its flat plug 22 through the slot 40 of the outer wall 10 molded integrally with the base plate 13 and riveted to the base plate 13 by means of a tubular rivet 41.
  • the bimetal 43 is inserted and welded into the space between the legs of the U-shaped tab 42 of the bimetal connector 38.
  • the adjusting screw 44 is in the threaded bore 45 of the bimetal connection 38. Its cone 46 presses against the nose 47 of the bimetal 43 and thus influences its pretension.
  • the bimetal 43 is heated by the PTC resistor 48, which can be round or angular.
  • the PTC resistor 48 is turned on by the spring 49 the bimetal 43 is pressed.
  • the spring 49 is specially hollowed out to accommodate the PTC resistor 48 (hollow 39).
  • the end 37 of the spring 49 opposite the hollow 39 is welded to the electrical heating connection 50, which is connected directly to the flat plug 21.
  • the tab 21 is inserted through the slot 51 in the outer wall 10 of the locking device 6. After installation, the angle 53 is pushed under the hook 54 protruding from the base plate 13, which prevents the heating connection 15 from moving upward.
  • the final tight fit of the heating connection 50 in the locking device 6 is ensured in the manner explained in more detail below by the printed circuit board 55.
  • the contact spring 56 is suspended with its shoulders 57 in the slots 58 of the bimetallic connection 38 and brought into tension by the toggle spring 59.
  • the tilt spring 59 is supported on the nose 60 of the bimetal 43 and the shoulder 61 of the contact spring 56.
  • the contact rivet 63 is riveted into the bore 62 of the contact spring 56 and interacts with the fixed contact 64, which is also formed by a contact rivet.
  • the fixed contact 64 is riveted onto the contact terminal 65, which is connected to the flat plug 20.
  • the flat plug 20 is inserted through the slot 67 in the outer wall 10 for its attachment. Its angle 68 is below the hook 69 of the base plate 13.
  • the final tight fit of the contact terminal 65 is also effected by the circuit board 55.
  • the locking slide 8 is pushed onto the nose 70 of the contact spring 56.
  • the guidance of the locking slide 8 in the base plate 13 is provided by the recess 72 in the base plate 13.
  • connection lugs 73 which pass through corresponding recesses 74 in the printed circuit board 55.
  • Printed connections 76 are applied to the circuit board 55 and are soldered to the corresponding connection lugs 73. In this way, the connections 38, 50 and 65 are initially defined. The connections 76 run into a tab 77 of the printed circuit board 55, which projects as a compact connector like the flat plug 20-22 over the outer wall 10 of the locking device 6.
  • a guide plate 78 protruding toward the closing end of the lock plate 1 is molded onto the lock plate housing 2.
  • the guide plate 78 carries mounting holes 79 for the door locking device on both sides of the lock plate guide.
  • the door locking device works as follows: With the locking movement of the door locking hook, the lock plate 1 is transferred into its closed position. Now the operating voltage of the electrical device of e.g. 220 V applied. The PTC resistor then heats up and the bimetal 43 is expanded upward (FIG. 6). After overcoming the dead center position of the rocker spring 59, the contact spring 56 snaps down, closes the contacts 63, 64 and at the same time moves the locking slide 8 into the lock plate recess 7, which is in the overlapping position with it. Only then is the electrical device connected to the operating voltage.
