Definitions

  • ABSTRACT A device for alternately changing the swing direction of the nozzle arm provided with a plurality of nozzles and installed in a table ware washer; said device comprising two channels for conveying liquid to be jetted from said nozzles to swing the nozzle arm, each channel comprising a liquid inlet compartment and a liquid jet nozzle compartment, said two compartments being disposed opposite to each other with respect to the axis of thenozzle arm (e.g., when the nozzles of one channel are directed right with respect to the nozzle arm axis, the nozzles of the other channel are directed left with respect to the nozzle arm axis) so that the liquid flowing in said two channels is shut out alternately by theruse of a ball.
  • said device is capable of alternately changing the liquid jet direction and thereby changing the swing direction of the nozzle arm alternately.
  • This invention relates to jet stream table ware washers and more particularly to devices for changing alternately and auto-matically the swing direction of the nozzle arm having a plurality of liquid jet nozzles.
  • an object of this invention is to provide a device having simple structure and which is capable of alternately changing the swing direction of the nozzle arm.
  • a second object of this invention is to provide a device capable of alternately changing the swing direction of the nozzle arm without depending on any drive source.
  • a third object of this invention is to provide a device manufacturable at a low cost and capable of alternately changing the swing direction of the nozzle arm with a high accuracy.
  • the nozzles of each channel are disposed symmetrically with respect to the axis of the nozzle arm.
  • the nozzle arm is swung in a specific direction by the reaction force produced by the detergent solution when jetted.
  • the nozzle arm is swung in the reverse direction.
  • the channels are alternately closed when the detergent solution is supplied. Namely, a valve ball moves from one channel to the other each time the operation of the solution circulating pump is stopped, whereby the channels are alternately closed.
  • the swing direction of the nozzle arm is changed over by the reaction force of the detergent solution jetted alternately from the nozzles of the two channels.
  • FIGS. 4 and 5 are sectional views taken along lines IVIV and VV in FIG. 3, respectively.
  • This changeover valve is provided with detergent solution jet nozzles in both directions with respect to the axis of nozzle arm 4.
  • the nozzle arm 4 is swung by the reaction force produced by the detergent solution when jetted from the nozzles.
  • the numeral 8 denotes one of two nozzles disposed at the changeover valve 6.
  • the major part of the detergent solution is supplied from the pipe 24 (FIG. I) through a passage 25 in the nozzle arm 4 and is jetted from the slit-like nozzle 5.
  • Another part of the detergent solution is applied to the changeover valve 6 from an inlet Ill or an inlet 15 and is jetted from a nozzle 12 or a nozzle 8 selected by a valve ball 7.
  • FIG. 3 shows a sectional view of the changeover valve 6 taken along line IlIIll in FIG. 2
  • FIGS. 4 and 5 are sectional views of the changeover valve 6 taken along lines IV-IV and VV, respectively, in FIG. 3.
  • valve ball 7 closes the nozzle 8 by way of the passage 20 defined by the upper guide wall 19 in the compartment C.
  • the detergent solution supplied via the inlets 15 and 11 is jetted from the nozzle 12, and the nozzle arm is swung in one direction by the reaction force of the jetted solution.
  • the diameter of the valve ball path in the compartment C be least different from the diameter of the valve ball '7 and that the amount of the detergent solution escaping through the gap in the valve ball path and passage 20 against the valve ball '7 be minimum.
  • the inner wall of the nozzle be sloped so as to bring the valve ball 7 into close contact with the nozzle as shown in FIG. 3. Then, by stopping the operation of the detergent solution circulating pump (not shown diagrammatically), the pressure of the detergent solution flowing into the changeover valve 6 is lowered and the force pressing the valve ball 7 against the nozzle 8 is released.
  • the valve kall 7, due to its own weight, moves to the compartment A (FIG. via the passage 9 defined by the guide wall 14 (FIG. 4).
  • the passage 9 has a slope to allow the valve ball 7 to move by its own weight.
  • valve ball When the pump is operated again, the valve ball is moved from the compartment A to the compartment B via passage 20 by the detergent solution flowing from the inlet 11 in the compartment A.
  • the nozzle 12 By this means, the nozzle 12 is closed, and the detergent solution supplied via the inlets 15 and 11 is jetted from the nozzle, thereby reversing the swing direction of the nozzle arm.
  • the diameter of the passage is slightly larger than the diameter of the valve ball 7.
  • An improvement in table ware washers comprising a basket means for holding table ware; a nozzle arm disposed swingably adjacent said basket means, a plurality of first nozzles in said nozzle arm for jetting a detergent solution forward the table ware, means for supplying said detergent solution to to said first nozzle, control nozzle means including second and third nozzles disposed at one end of said nozzle arm from which the detergent solution is jetted in the direction opposite to the axis of said nozzle arm for exerting a swing force on said nozzle arm in opposite directions, and changeover valve means for alternately applying the detergent solution to said second and third nozzles in response to successive reductions in the pressure of the detergent solution supply to the changeover valve whereby the swing direction of the nozzle arm is alternately changed; the improvement comprising said changeover valve including a housing having second and third compartments provided with said second and third nozzles, respectively, for jetting the detergent solution in mutually opposite directions with respect to said nozzle arm so that a swing force is exerted on said nozzle arm, first and
  • said partition means includes a sloped passage disposed in said housing so that said ball can be moved by its down weight from the third compartment to said first compartment and from the second compartment to said fourth compartment.
  • an improved table ware washer comprising a basket means for holding table ware, a nozzle arm disposed swingably adjacent said basket means, a plurality of first nozzles disposed in said nozzle arm for jetting a detergent solution toward the table ware, means for supplying said detergent solution to said first nozzle, and changeover valve means disposed in said nozzle arm; the improvement comprising said changeover valve means including first and second inlets for introducing the detergent solution into said changeover valve means, first and second outlets disposed in said changeover valve means for jetting the detergent solution in the direction opposite to the axis of said nozzle arm for exerting a swing force on said nozzle arm in opposite directions, and a ball positioned in said changeover valve means, said ball being moved between one of the first inlet to the first outlet and the second inlet to the second outlet by the pressure of said detergent solution acting directly on the surface of said ball.
