Definitions

  • the invention relates to a security lock for access doors, inside a drum of a washing machine.
  • the access doors inside the drum of a washing machine, are subjected, during the rotation under load of the drum, in particular during the spinning operations, to significant pressures likely to cause the untimely opening of the doors and the eviction of the linen resulting in material damage sometimes significant.
  • hooks integral with one of the doors, and slots made in the other door, arranged in such a way that, when the doors are closed under the action of their return springs, the so-called hooks penetrate directly into the slots, kept in the shape of their beak; they come out of it just as easily when a push is exerted on the doors from the outside, as is the case when the user wishes to intervene inside the drum to load or unload the latter.
  • doors comprising a hook closure, with a safety device opposing the untimely recoil of the hooks and their removal from the notches when said doors are closed.
  • the object of the present invention is to remedy these drawbacks.
  • This invention as characterized, in claim 1 solves the problem of creating a safety lock for washing machine drum doors, the stopper of which can be directly operated without an intermediate member and can be completely housed in a recess produced in the door comprising the closing hooks.
  • the advantages obtained thanks to this invention consist essentially in that the security lock does not have any roughness capable of catching the laundry, and in that its operation simultaneously causes the doors to open.
  • the figures show the doors 10 and 20 of a drum, secured by means of hooks 12, 13 and 14 and slots 22, 23 and 24 , of which the door 10 , comprising the recess 11 , is provided with a lock 30 consisting of a plunger 31 with base 32 biased towards the flange 41 of a hollow base 40 by a spring 50 ; a clearance J having been made between the pusher 31 and the flange 41 and an angle alpha having been given to the flange 41 of the hollow base 40 relative to the flat bottom of the recess 11 , in the direction opposite to the hooks 12, 13, 14 .
  • FIGS. 1 and 2 By examining FIGS. 1 and 2 simultaneously, it can be seen that, in the closed position of the doors 10 and 20 , the end of the door 20 , comprising the slots 22, 23 and 24 , is situated against the push-button 31 of the latch 30 , just above the flange 41 of the hollow base 40 of said lock 30 . Said pusher 31 is then supported, by its base 32 , against the flange 41 of the hollow base 40 .
  • a clearance J of a few tenths of a millimeter, has been formed between the edge of your collar 41 of the hollow base 40 and the pusher 31 , as well as an alpha inclination of approximately 2 ° in the direction opposite to the closing hooks.
  • This alpha inclination also favors the buckling of the spring 50 when a push is exerted on the pusher 31 and, consequently, a tilting of the said pusher in the direction opposite to the hooks, facilitating the release of the end of the door. 20 .
  • the security lock according to the invention is intended mainly to equip the drums of a washing machine, but it could also be used on any rotary drum, the doors of which are secured to the closure by a system of hooks.
