Definitions

  • the present invention relates to dish-washing machines, of the type in which the vessel defining casing has a door, a flap or shelf arranged on one of the side surfaces of the casing for moving a rotatable crockery carrier in and out of the casing and in which operatively stationary washing nozzles are arranged outside the carrier.
  • Dish-washing machines having a revolving crockery basket and stationary washing nozzles provided outside the basket are known. In these machines it is diflicult to move the crockery basket into and out of the machine so that the introduction and removal of the crockery to be washed presents difiiculties.
  • the present invention obviates the disadvantages of the prior art indicated above by rotatably mounting the crockery-carrier upon an arm which can be swung laterally out of the dish-washing machine, the pivot axis of the basket support arm being located in one corner of the casing adjacent the door.
  • a dish-washing machine which has an operatively rotary crockery-carrier which can be swung out of and into the casing with a minimum effort. No slideways, exposed to contamination, are required.
  • the relatively movable parts of the bearings of the rocking arm can be protected against fouling by simple means, such as ordinary cover flaps or the like.
  • the crockery to be washed may be conveniently placed in the crockery-carrier when the crockery basket is swung out of the casing.
  • the carrier may advantageously be constructed in a known manner as a basket.
  • the crockery basket may be easily taken olf the swungout carrier for cleaning.
  • the crockery basket can be easily swung into the machine where it is set in rotation, during the washing operation, by a suitable drive.
  • the drive for the basket is preferably that disclosed in our co-pending application Serial No. 187,705 filed April 16, 1962, for Dish-Washer Basket Drive based on West German application No. B 64,779 Ic/34c filed November 14, 1961.
  • a further feature of the dish-washing machine according to the invention involves arranging the washing or rinsing nozzles in the swinging arm and in the column that holds the rocking arm.
  • the swinging arm is mounted on a column arranged adjacent the casing door, and secured, for instance,
  • the vertical column and the basket carrying arm pivoted thereon are, according to a further feature of this invention, made hollow and supply the washing water to the washing nozzles located on them.
  • the vertical column may be stationary and the carrier arm may be so journaled to swing about this column.
  • two sealing packings are required, one above and one below the scavenging-fluid supply to the swinging arm on the column.
  • the carrying arm prefferably fixed to the column so that when the crockery basket is swung out the column participates in the swinging movement.
  • sealing packings are required on the supply of washing fluid, preferably at the lower end of the column.
  • the washing nozzles on the carrying arm and on the column may be provided in readily removable nozzle-carriers, to facilitate cleaning of the nozzles.
  • the nozzlecarriers may be sealed, in relation to the carrying arm and to the column, by means of simple packings.
  • the pivoted basket-carrying arm is connected to the door of the machine casing so that it and the basket thereon are positively swung out of the machine when the door is opened, and into the machine when it is closed.
  • FIGURE 1 is a perspective view of a dish-washing machine according to the invention.
  • FIGURE 2 shows the carrying arm of the crockery basket, with the Vertical column.
  • FIGURE 1 illustrates in detail the vessel defining machine casing 1, at one side of which a pivoted door, flap or shelf 2 is provided.
  • a vertical column 3 Within the machine casing 1, in a corner thereof adjacent the door 2, is arranged a vertical column 3.
  • Column 3 carries at its lower end a rockable basket carrying arm 4.
  • a basket-like crockery carrier 6 is rotatably journaled.
  • the crockery-carrier 6 is rotated during the washing operation, for instance, by way of a drive roller 8 as is fully disclosed in our aforesaid copending application Serial No. 187,705.
  • the column 3 is made hollow for the purpose of supplying washing fluid.
  • Removable washing nozzles 9 are arranged in column 3.
  • a set of nozzles 10 is similarly provided on the swingable carrying arm 4.
  • FIGURE 2 shows more clearly the basket carrying arm 4 which swings about the vertical column 3.
  • the nozzle-carrier 9 is shown detached from column 3.
  • the supply of washing liquid to the nozzlecarrier 9 from the vertical column is effected through a longitudinal slot 11, which is sufficiently wide that choking or clogging is impossible.
  • the nozzle-carrier 9 is secured to the column 3 by the engagement of the slots or notches 12 located at the lower end of the nozzle-carrier 9 with corresponding pins 13 on the column 3 and by the subsequent closure of the simple locking clamp 7 provided on the column 3 at the upper end of nozzle-carrier 9.
  • the nozzle-carrier 10 is similarly secured to the basket carrying arm 4.
  • a dish washer having a casing formed with a side opening, a door for said side opening and mounted on said casing, and a rotary basket-like crockery carrier
  • the improvement comprising a vertical rigid hollow support column mounted in said casing in one corner adjacent said side opening, a hollow arm supported on said column for pivotal movement about the axis thereof, and means supportingly mounting said carrier on said arm for rotation about an axis extending in spaced apart parallel relation to the axis of said column and permitting said carrier to be swung by said arm laterally through said side opening for movement into and out of said casing, said column and said arm each having a longitudinal row of nozzles directed inwardly of said casing whereby fluid introduced into said column and said arm is adapted to be discharged through said nozzles in a 20 plurality of jets onto crockery contained on said carrier.
