Definitions
- the invention relates to an electromanetic door lock for machines with a rotary latch, which comprises a door-side block, and a pivot lever blocking the rotary latch, which is locked by an electromagnetically actuated rocker.
- Electromagnetic door locks of the type mentioned in the generic term have been used in washing machines, dishwashers, centrifuges and similar devices in which any danger to the operator could arise from the interior. Most of these machines have a large, circumferential seal, so that the catch is exposed to considerable pressure.
- the object of the invention is to provide an inexpensive locking device for low voltage, which is also "finger-safe" according to the VDE guidelines. This object is achieved with the means specified in the claim.
- Fig. 1, 1 denotes the housing base plate, in which a main bearing pin 2 for the rotary latch 3, a bearing pin 4 for the pivot lever 5 and a bearing pin 6 for the rocker 7 are fastened.
- An electromagnet 8 is connected to the left end of the rocker 7 via its armature 8a.
- query levers 9, 10 are mounted on the bolt 2.
- a spring indicated by arrow 11 serves to turn these levers clockwise.
- the rotary latch 3 is shown in the closed state. Its claw encompasses the door-side block 12 indicated by dash-dotted lines.
- the lower left end of the rotary latch has a recess 3a which bears against a roller 13. This is mounted on the pivot lever 5 via a pin 14.
- the lever carries a further pin 15 with a smaller roller 16. This roller abuts the right end of the rocker 7, as a result of which the pivot lever 5 and thus also the rotary latch 3 are blocked.
- the electromagnet 8 When the electromagnet 8 is energized, it pulls its armature 8a and thereby moves the rocker 7 clockwise. The right locking edge 7a of the rocker 7 runs down over the roller 16, whereby the blockage of the lever 5 is released is. If a pulling force is now exerted on the rotary latch 3 via the block 12, the projection 3b presses the pivot lever 5 to the left so that the rotary latch can open.
- the query levers 9, 10 pivot upward, as a result of which they block the pivot lever 5 in the position typical for the unlocking.
- Fig. 2 shows the position of all parts with the door open.
- a leg spring 17 ensures that the pivot lever 5 bears against the query levers 9, 10.
- FIG. 3 the complete door lock is shown in plan view. An almost mirror image of the same housing cover plate is placed on the base plate 1, which has corresponding holes at least for the bearing bolts 2 and 4.
- a microswitch 19 can be seen, which is fastened with a screw 20.
- This microswitch to be installed from the outside is actuated by a bracket 21 shown in FIGS. 1 and 2, which is connected to the pivot lever 5.
- 22, 23, 24 through holes are designated, which are used to attach the housing to the door frame.
- a housing opening 25 provides a view of the rotary latch 3 and the query levers 9, 10. Actuating surfaces 9a, 10a are formed on these levers.
- the block 12 is held by two fastening tabs which hit the surfaces 9a, 10a when the door is closed, while at the same time the block 12 presses the catch 3 downwards.
- the query levers 9, 10 release the pivot lever 5 so that it can pivot counterclockwise and can lock the rotary latch 3 via the roller 13.
- the microswitch is only actuated when the pivot lever 5 assumes the position shown in FIG. 1. In this position, the lever 5 can then be blocked again by the rocker 7, this rocker being tilted into the locked position by the force of a weak spring indicated by the arrow 26.
- the query levers mounted to the left and right of the rotary latch have the task of outwitting the door lock to prevent. To lock the rotary latch and to actuate the microswitch, it is not sufficient to push the rotary latch down with the door open. It should therefore be prevented that the machine - wanted or unwanted - can start with the door open.
- the microswitch is only activated at the moment when the swivel lever has locked the rotary latch. Conversely, the microswitch interrupts when opening before the rotary latch is released.
- the magnetic force required to trigger the rocker 7 is very low because its locking edge 7a can run over the smooth-running roller 16.
- the longitudinal axis AB of the rocker 7 encloses an angle of just over 90 ° with the longitudinal axis CD of the pivoting lever 5. It is thereby achieved that, in the event of a tensile force on the rotary latch 3, the pivot lever 5 remains in the stable dead position despite the forces transmitted to it, because no torque is transmitted to the rocker 7. From this locked position, the release force of the magnet is so low that a low-voltage magnet, e.g. for 12 volts, can be used. This makes it extremely easy to comply with the safety regulations, especially for devices with moisture release.
- an emergency release element 27 shown here as a pulling element, which acts on the rocker 7. It would be even more inconspicuous to make a small hole in the housing on the magnetic side of the rocker 7, through which the initiate can insert a pin.
- rocker 7 is constructed so that the center of mass coincides with the axis of rotation (bearing pin 6). This prevents the rocker from being knocked out or unwanted from the locked position as a result of impacts or imbalances in the centrifuge or centrifuge and the door from opening when the machine is running.
- the electromagnetic door lock described can be used with great gain in operating safety for all devices and machines that have rotating parts or work with dangerous liquids and vapors. These are preferably spin dryers and washing machines and dishwashers, as are used in industry or in the service sector.
