Definitions

  • the invention relates to a door locking device for electrical devices with the features specified in the preamble of claim 1.
  • Door locking devices are used for the above functions, as are known, for example, from FR-A-2381126, FR-A-2477620 or US-A-3617957.
  • a plate-shaped locking slide is guided on the insulating housing between a release and a blocking position in its flat plane in a longitudinally displaceable manner.
  • the locking slide serves to fix a locking hook of the door of the respective electrical device.
  • the locking slide has a driver in the form of a side nose, which can actuate further control contacts.
  • this driver is realized by a movement-coupled slide.
  • a locking slide which is longitudinally displaceable in the insulating housing can directly engage in the movement path of the locking slide, for example via bores (US-A-3617957) or recesses (FR-A-2477620), with which the latter its blocking position is fixed and the door of the electrical device is locked.
  • An optionally externally heated bimetal strip is used to drive the locking slide and to actuate further switching contacts of the door locking device. By switching these contacts, a control signal can be generated with which the closed state of the door can be monitored by the device control.
  • the displacement drive itself takes place through the engagement of the bimetal or an extension thereon in a recess in the locking slide. Due to the current applied to the bimetal and the resulting heating, the latter is deflected and the locking slide is moved into the bore of the locking slide in its engagement position.
  • the mutual arrangement of the locking and locking slide in the door locking devices according to the prior art has various disadvantages.
  • the locking slide which is usually made of plastic for cost and weight reasons, engages directly in the bore or recess in the locking slide.
  • the locking slide with its bore or recess edge exerts a great shear effect on the locking slide, which can be easily destroyed. This will lock the door during operation of the electrical Device lifted, which is extremely worrying for safety reasons.
  • the switching contacts of the door locking device built in for monitoring purposes can also be actuated when the locking slide is violently destroyed.
  • the locking slide in the locking device according to US-A-3617957 can be moved into its blocking position and thereby actuate switching contacts via the driver coupled to it, whereupon the device can be put into operation without the locking slide being properly locked. This possibility must also be excluded for safety reasons.
  • the object of the invention is to improve a door locking device of the type mentioned at the outset in terms of safety.
  • the predetermined breaking point between the driver and the locking slide is used so that the door locking device yields there when the locking hook of the closed door is actuated by force, that is to say when the locking slide is forcibly returned to its release position.
  • the movement coupling between the locking slide and the driver is canceled.
  • the locking slide can be brought into its release position for the locking hook of the appliance door by force. In doing so, however, it inevitably leads the locking slide back into its release position with respect to the driver. This is pushed back into its switch-off position and the switch contacts connected to the driver are opened automatically and can then no longer be closed from the outside due to their drive inaccessibility, which further operation of the device and definitely prevents drum rotation in particular. It is impossible to restart the electrical device.
  • the locking slide In its position of engagement in the movement path of the driver, the locking slide is arranged in front of its end face pointing in the direction of the release position and is supported on the housing with its side facing away from the driver.
  • the door locking device is further improved in terms of safety.
  • the sliding movement of the locking slide is transmitted particularly easily to the locking slide and this is acted upon in its unlocking direction via the lateral control bevel edge of the actuating recess.
  • two strip-shaped bimetals are arranged essentially parallel to the direction of displacement of the locking slide and with opposite deflection directions in the housing.
  • a heating resistor is inserted between the two bimetals. This therefore fulfills a double function, namely heating and mechanical coupling between the two bimetals.
  • One of the two bimetallic ends is connected to the locking slide.
  • the other bimetal is supported with its deflecting end on a stop fixed to the housing from.
  • the mechanical coupling of the bimetals via the heating resistor increases the deflection movement of the first bimetal through the deflection of the second bimetal (claim 6).
  • the bolt slide can therefore travel through the bimetal drive a relatively high displacement path, which ensures reliable blocking of the driver and thus of the locking slide in the blocking position.
  • An optimization with regard to the displacement path is achieved by the geometric arrangement of bimetals and heating resistor to one another.
  • bimetal assembly is specified in claims 8-10, in which a snap bimetal and an elongated contact spring are used in particular. These components require a momentary change in the drive of the bolt slide and avoid the creeping drive movement of the bimetallic assembly according to claims 5-7. This precludes the electrical closing of the various control and signal contacts in the door locking device before the final mechanical locking thereof. This means that there is no noticeable time difference between the closing of the contact and the locking, which in turn offers safety-related advantages.
  • the bimetallic assembly according to claims 8-10 is simpler and more cost-effective compared to that according to claims 5-7, since only one bimetal is used.
  • a contact spring is provided as a second counter-bearing element for perfect and reliable contacting of the PTC heating resistor used to heat the snap bimetal.
  • the special construction of the snap bimetal specified in claim 10 is particularly simple in terms of production technology, since the bimetal blank is a simple stamped part, the snap action of which is achieved only by bending the bimetal legs and connecting them in a mutual overlapping position.
  • the displacement directions of the driver and the locking slide and the direction of deflection of the bimetal are aligned parallel to the flat plane of the plate-shaped locking slide. Since all kinematic processes within the locking device consequently take place in a plane parallel to the flat plane of the locking slide, the overall height of the door locking device according to the invention can advantageously be kept low.
  • the door locking device has an essentially cuboid insulating housing 1 molded from plastic, which is composed of a shell-shaped lower part 2 and a cover 4 which can be snapped on by means of spring hooks 3 on the side.
  • a lateral extension 5 of the bottom 6 of the lower part 2 sleeve-like fastening elements 7 are integrally formed, into which screws or rivets for fastening the door locking device to the corresponding electrical device - for example a washing machine - can engage.
  • the rectangular through opening 8 for the locking hook 9 (FIG. 6) of the door to be locked is also molded in the center.
  • the lower part produced as a one-piece plastic injection-molded part has 2 different webs, partitions and the like. (For example, intermediate wall 30, intermediate web 32), by means of which the functional parts of the door locking device inserted into the lower part 2 are held, guided and aligned.
  • the inner structure of the door lock device will be explained below.
  • An essential part of it is the approximately rectangular, plate-shaped locking slide 11, which is under the bottom 6 of the Lower part 2 in the slot 12 formed between the bottom 6 and the extension 5 between a release (Fig. 2) and a blocking position (Fig. 3, 4) in its flat plane is guided longitudinally.
  • the locking slide 11 has an approximately square engagement opening 13, which is provided with bending tabs 15 on its side edges arranged at right angles to the direction of displacement 14.
  • the locking slide 11 has on its longitudinal side edges offset from one another recesses 16, 17.
  • the rear recess 16 serves to receive the pin 18 of the driver 19, which is guided on the longitudinal side of the lower part 2 parallel to the direction of displacement 14 of the locking slide 11 in the insulating housing 1.
  • the driver 19 itself is a block-like molded plastic part which carries at its end pointing in the blocking direction 20 a contact bridge 21 which interacts with two mating contacts 22 fixed to the housing.
  • the two mating contacts 22 are arranged one above the other and each have terminal lugs 23.
  • the contact bridge 21 is displaceably guided on the driver 19 and is subject to the action of the compression spring 25 clamped in a pocket 24 of the driver 19.
  • a side extension 27 is attached to the end (end face 50) of the driver 19 pointing in the release direction 26.
  • a compression spring 29 is clamped between the and a counter bearing 28 fixed to the housing. This acts on the driver 19 and thereby the locking slide 11, which is coupled to it via the pin 18 in the release direction 26.
  • the counter bearing 28 together with the intermediate wall 30 of the lower part 2 serves as a longitudinal guide for the driver 19.
  • the locking slide 33 is guided to be longitudinally displaceable (direction of displacement 14 ').
  • the trajectories of the driver 19 and the bolt slide 33 intersect in the area of in Release direction 26 of the end (end face 50) of the driver 19.
  • the locking slide 33 has a cross slot 34 approximately in the center, in which, in the embodiment according to FIGS. 2-10, the deflecting end 35 of a first bimetal 36 arranged parallel to the displacement direction 14 engages.
  • Parallel to this first bimetal 36 is a second bimetal 37, which is supported with its deflecting end 38 on the intermediate web 32.
  • the two bimetals 36, 37 are connected to one another both electrically and mechanically via an PTC heating resistor 39 placed between them. Furthermore, they are anchored to terminal lugs 41 with their cranked fixed ends 40.
  • an elongated snap bimetal 55 and a support contact spring 56 are used instead of the two bimetals 36, 37. These components are anchored analogously to connecting lugs 41 and clamp the PTC heating resistor 39 between them for the electrical and mechanical connection.
  • the snap bimetal 55 engages with its deflecting end 35 in the transverse slot 34 of the locking slide 33.
  • the support contact spring 56 is supported with its free end 57 on the intermediate piece 32. It is frame-shaped and has in its frame opening a spring tongue 58 which acts on the PTC heating resistor 39.
  • the snap bimetal 55 suddenly snaps from its unexcited position shown in FIG. 12 to the excited position shown in FIG. 13, whereby an instantaneous switching between the unlocked and the locked position of the latch slide is achieved.
  • the snap bimetal 55 is made from a (not shown) U-shaped bimetal blank, the U-leg ends 59 forming the deflecting end 38 of which are bent inward and welded to one another in the overlapping position (FIGS. 16, 17).
  • two pairs of contact springs 42, 43 are arranged parallel to the displacement direction 14 and at a distance from one another.
  • one contact spring of each pair of springs rests with its free end on lateral extensions 44, 45 of the locking slide 33.
  • the contact springs 42, 43 are riveted with their fixed ends with connecting lugs 46.
  • a locking hook 9 of a (not shown) door of the electrical device can be pushed through the through opening 8 in the extension 5 and engage in the engagement opening 13 in the locking slide 11. Since the locking hook 9 is spring-loaded in the blocking direction 20, it moves the locking slide 11 in the blocking direction 20 with its hook part 47. The hook part 47 also engages behind the side edge 54 of the extension 5 of the lower part 2 which delimits the opening 8 on the blocking direction. This position must be by the locking slide 11 be secured to ensure locking of the door. This is done indirectly via the driver 19, which is moved together with the locking slide 11 by the engagement of the locking hook 9 in the blocking direction 20.
  • the driver 19 closes the contact formed from its contact bridge 21 and the mating contacts 22 fixed to the housing. This can be a signal for the control of the electrical device generated that the locking hook 9 is in the blocking position.
  • a voltage can now be applied to the two connecting lugs 41, which heats the PTC auxiliary resistor 39 and thus leads to a deflection of the two bimetals 36, 37 and the snap bimetal 55 (FIGS. 4 and 13).
  • the deflection movement of the (snap) bimetal 36 or 55 engaging in the locking slide 33 is transmitted to the locking slide 33, which thus pushes in front of the end (end face 50) of the driver 19 pointing in the release direction 26. Consequently, this and at the same time the locking slide 11 are locked in their blocking position.
  • a control signal assigned to the locking state can be generated for the control circuit of the electrical device equipped with the door locking device.
  • the supply voltage of the PTC heating resistor 39 is switched off. Due to the slow cooling of the bimetals 36, 37 or the snap bimetallic element 55, the latch slide 33 is only slowly or snapped back with a certain time delay and thus the release of the driver 19 and the lock slide 11 is the door secured with the locking hook 9 So only open after a certain delay, which ensures that the door lock is only released when rotating parts of the device have come to a standstill.
  • the sliding directions (14, 14 ') of the driver 19 and the locking slide 33 and the deflection directions 48, 49 of the bimetals 36, 37 and the snap bimetallic 55 are aligned parallel to the flat plane of the plate-shaped locking slide 11.
  • the latter is indirect through the intervention of the Latch slide 33 locked in the movement path of the driver 19.
  • the pin 18 of the driver 19 engaging in the recess 16 has a predetermined breaking point 51 which breaks when a certain actuating force (for example 500 N) is exceeded.
  • a certain actuating force for example 500 N
  • the locking slide 11 and the locking hook 9 are released, but further operation of the electrical device is prevented by this special design.
  • the lateral control oblique edge 52 of the recess 17 acts on an extension 53 of the locking slide which penetrates the bottom 6 and engages in the recess 17 in such a way that the locking slide 33 counteracts the bimetallic forces in FIG Fig. 2 and 11 shown release position is spent.
  • the contacts formed by the contact springs 42, 43 are opened, whereby the further operation of the electrical device is completely prevented.
  • the driver 19 is released, which, under the arrival of the compression spring 29, also moves into the position shown in FIG Fig. 2 and 11 position shown is spent.
  • the contact bridge 21 thus lifts off the counter contacts 22 and thus opens the door contact. Since the driver 19 and the locking slide 11 are decoupled from movement due to the breakage of the predetermined breaking point 51, the locking hook 9 can indeed move the locking slide 11 back into its blocking position, but the miner 19 is not moved in the process.
  • the contact formed by the contact bridge 21 and the mating contacts 22 thus remains open, thereby preventing the electrical device from starting.
  • the door locking device is therefore only ready for use again when it has been brought into a proper state with an intact driver 19.
  • the special geometric arrangement of the two bimetals 36, 37 and the PTC heating resistor 39 is still to be explained with respect to the first bimetal design.
  • the PTC heating resistor 39 Based on the length of the bimetal 36 actuating the locking slide 33, the PTC heating resistor 39, starting from its fixed end 40, is arranged approximately in the region of a third of the total length of the bimetal 36. With regard to the second bimetal 37, it lies approximately in the middle. This arrangement is achieved by an arrangement of the fixed ends 40 offset in the direction of displacement 14.
  • the deflection movement of the bimetal 37 is transmitted to the bimetal 36 via the PTC heating resistor 39.
  • the deflection of the deflection end 35 and thus the locking distance that can be covered by the locking slide 33 is considerably increased by the superimposition of the deflection movements of the two bimetals 36, 37.
  • both embodiments have in common that it lies loosely in the frame opening of a frame-shaped guide part 61, which in turn is seated in corresponding housing recesses.
  • the height of the PTC heating resistor 39 is thus secured with respect to the two bimetals 36, 37 or the snap bimetal 55 and the support contact spring 56.
  • the guide part 61 serves as an assembly aid.
  • terminal lugs 23, 41, 46 of the various contacts and springs are arranged in such a way that cable plugs in the "Rast 5" version are used and these can be contacted in a manner that prevents them from being mixed up by appropriate coding.
  • all connections and moving parts are covered so that they are safe to touch, for which purpose cover 10 on cover 2 is used in particular.
  • the locking slide 11 can only be influenced from the outside via the locking hook 9.
