Definitions

  • This invention relates, in general, to laundry apparatus and, more particularly, to door lock structure therefor.
  • the general object of this invention is to provide a new and improved door lock structure for laundry apparatus.
  • a door lock structure comprising a latch and a catch arrangement wherein the catch passes through an opening in the latch.
  • the catch has a finger-like extremity which engages the latch such that the door structure, with which they are associated, can only be opened through movement of the latch.
  • a tongue member movably associated with the catch is operatively connected to a solenoid, for movement, upon energization of the solenoid, into the above-mentioned opening into a position intermediate one side of the opening and the catch to thereby block movement of the latch.
  • the solenoid is energized through a switch, actuated by a conventional timer at predetermined points in the cycle of operation of the apparatus.
  • FIG. 1 is a perspective view of a clothes washing machine incorporating the invention
  • FIG. 2 is a cross-sectional view taken on the line II-II of FIG. 1;
  • FIG. 3 is a view similar to FIG. 2, but with the latch of the lock structure thereof, representing the invention, in an unlatching position;
  • FIG. 4 is a view of an interlock forming a part of the lock structure shown in FIG. 3;
  • FIG. 5 is a view taken generally along the line VV of FIG. 2.
  • reference character 10 designates generally a tumbler type washing machine comprising front, top, and side walls 11, 12, and 13, respectively.
  • the front wall 11 supports a door structure 14 in registry with an opening 16 in the front wall 11.
  • the door structure comprises front and rear panels 17 and 18 (see FIGS. 3-5).
  • the front wall 11 has attached thereto a catch member 19 and a solenoid 21.
  • the catch member 19 forms a part of a door lock structure generally indicated at 22, which structure comprises a latch member 23 movably mounted between the panels 17 and 18 of the door structure.
  • a spring 24 (see FIG. 5) captured through cooperation of a pair of fasteners 25 and a protuberance 26 of the latch member 23, serves to bias the latch into a locking position.
  • Another function of the fasteners 25 is to retain a guide member 27 for the latch.
  • the catch member 19 has a finger-like extremity 28 which, in the door closed position, extends through an aperture 29 in the panel 18 and an aperture 30 in the latch member 23. In the door latching position, illustrated in FIG. 2, the finger-like extremity engages the latch member 23 as indicated at 31. Through manual movement of the latch member downwardly, as viewed in FIGS. 2 and 3, against the bias of the spring 24, the extremity 28 can clear the lip 23' of the latch member as the door structure 17 is moved to the left, as viewed in FIG. 3.
  • the solenoid 21 comprises a body portion 32 having a cylindrical bore 33 therethrough which has an insert 34 therein.
  • a soft iron core 36 is disposed within the insert 34 and is attached to a tongue element 37 by means of a rod 38.
  • a pair of terminals 39 provide means for connecting the solenoid to a circuit for providing electrical power thereto.
  • the core and tongue element In the deenergized condition of the solenoid the core and tongue element occupy the position shown in FIGS. 2 and 3, by virtue of the bias provided by a coil spring 41, concentrically mounted on the rod 38 intermediate the core 36 and the tapered end of the insert 34.
  • the core, and consequently, the tongue element are moved to left guided by the upper surface of the catch member 19 as viewed in FIG. 4. In this position of the tongue element 37, downward movement of latch 23 is prevented.
  • Energization of the solenoid 21 is accomplished automatically through a timer-actuated switch (not shown) which is closed at predetermined periods during the cycle of operation of a timer control generally indicated at 42 (see FIG. 1).
  • a timer control generally indicated at 42 (see FIG. 1).
  • the closure of the aforementioned switch takes place during the spin or water eX tracting portions of the cycle of operation. It will be appreciated however, that the switch could be closed at other times or could be closed during the entire operation of the machine.
  • the spring 41 could be used to bias the tongue element 37 into the blocking position shown in FIG. 4 and that the energization of the solenoid 21 would be used to effect unblocking.
  • lock structure including a latch having a body portion with an opening therethrough and movably mounted on said door structure and a cooperating catch including a finger-like member which extends through said opening and carried by said cabinet structure;
