The upper rinsing nozzle 21 and the lower rinsing nozzle 22 are rinsed via a water supply pipe 23. It is connected to the pump P2. The suction port of the rinsing pump P2 communicates with the rinsing tank 24, and clean water heated to a temperature suitable for rinsing with a gas booster or an electric booster is stored in the rinsing tank 24.

  Thus, as shown in FIGS. 3 and 4, the lower cleaning nozzle 15 accommodated in the cleaning region S1 is detachably attached to the water supply pipe 16 extending in the vertical direction. The lower cleaning nozzle 15 extends in the horizontal direction perpendicular to the transport direction of the rack 4, and extends in the transport direction of the rack 4 with four nozzle portions 33 arranged in parallel to each other. Cylindrical coupling into which a coupling part 32 that couples the base part of each nozzle part 33 and a branch pipe part 16a that protrudes from the coupling part 32 in the opposite direction of the nozzle part 33 and branches horizontally from the water supply pipe 16 are inserted. Part 31.

  When the branch pipe portion 16 a is inserted into the coupling portion 31, the lower cleaning nozzle 15 can tilt with respect to the branch pipe portion 16 a, and cleaning water can flow from between the branch pipe portion 16 a and the coupling portion 31. In order to prevent leakage, the inner diameter of the coupling portion 31 is slightly larger than the outer diameter of the branch pipe portion 16a, and a packing such as an O-ring is fitted into the inner wall of the coupling portion 31.

  On the upper surface of each nozzle portion 33 extending in the horizontal direction, six or seven injection holes 34 for injecting cleaning water toward the tableware 3 accommodated in the rack 4 are formed, respectively. An injection hole 35 for injecting cleaning water toward the side wall surface 27 extending in the vertical direction is formed at the tip 36 of 33.

  Further, a U-shaped engaging portion 37 extending in the transport direction of the rack 4 is fixed to the front side of the lower surface of each lower cleaning nozzle 15, and this engaging portion 37 is attached to the bottom surface 10 a of the cleaning chamber 10. It is fitted to a fixed positioning member 19 having a rectangular cross section.

  In addition, as shown in FIG. 3, the cleaning water sprayed from the spray holes 35 away from the tip 36 of the lower cleaning nozzle 15 enters the tableware 3 located at the end of the rack 4 in the cleaning region S1. A guide member 40 that is directed toward the vehicle is disposed. The guide member 40 is separated from the tip 36 of the lower cleaning nozzle 15 and is formed of a curved pipe portion 42 so as to avoid obstacles such as the conveyor 20 and the rack rail 25 from the inlet 41 facing the injection hole 35. It is curved and extends upward, and the outlet 43 is arranged at a position where the washing water hits the exposed portion of the tableware 3 in the rack 4 being conveyed.

  The guide member 40 is fixed to the side wall surface 27 by welding or the like via a bracket. Note that the distance between the inlet 41 and the tip 36 of the lower cleaning nozzle 15 is longer than the length at which the tip of the branch pipe portion 16 a is inserted into the coupling portion 31.

  The inlet 41 is located on an extension line of the lower cleaning nozzle 15 and has a funnel shape that expands toward the injection hole 35. The maximum inner diameter of the inlet 41 is sufficiently larger than the outer diameter of the injection hole 35 so that the washing water injected from the injection hole 35 can be sufficiently taken in.

  The washing water introduced from the inlet 41 is jetted from the outlet 43 while being drawn to one side by the centrifugal force in the pipe portion 42. The outlet 43 is disposed at a position where at least the side wall surface 27 side on which the cleaning water is jetted avoids obstacles such as the rack 4, the conveyor 20, and the rack rail 25, and the tableware at the end accommodated in the rack 4 being transported 3 is facing the upper end.

Furthermore, in this conveyor type tableware washing machine 1, the guide member 40 is arranged away from the tip 36 of the lower cleaning nozzle 15 so that the lower cleaning nozzle 15 can be detached without being obstructed by the guide member 40. Is possible.

  Further, since the guide member 40 can guide the cleaning water in a desired direction, for example, the cleaning water can be applied to the tableware 3 protruding from the rack 4. An injection hole 35 for injecting cleaning water along the extended line of the lower cleaning nozzle 15 is provided in the lower cleaning nozzle 15, and the guide member 40 is disposed using a gap between the rack rail 25 and the side wall surface 27. Thus, it is possible to prevent the course of the cleaning water sprayed from the spray holes 35 from being obstructed by obstacles such as the rack 4, the conveyor 20, the rack rail 25, and the cleaning efficiency can be further improved. .

  Moreover, since the washing water introduced into the guide member 40 can be prevented from splashing outside the guide member 40 by adopting the pipe-shaped guide member 40, almost all of the washing water introduced into the guide member 40 is removed. It can be made to inject from the exit 43, and cleaning efficiency can be improved more.

  Next, with reference to FIG. 5, the operation | movement which removes the lower side washing nozzle 15 from the conveyor type dishwasher 1 comprised as mentioned above is demonstrated.

You may make it arrange | position a member.

  Further, the guide member does not necessarily have a pipe shape, and may be formed in a curved longitudinal half pipe shape, for example, like a guide member 50 shown in FIG. According to the guide member 50, it is possible to guide the cleaning water sprayed from the spray holes 35 of the lower cleaning nozzles 15 while reducing the material cost. A guide member 60 shown in FIG. 7 may be formed in a curved plate shape having a width wider than that of the lower cleaning nozzle 15. According to the guide member 60, the cleaning water sprayed from the spray hole 35 can be guided regardless of the position of the nozzle part 33 and the spray hole 35. Even if the cleaning nozzle is replaced, the guide member need not be changed accordingly.

  Further, the injection hole 35 is not necessarily formed so as to inject the cleaning water along the extended line of the lower cleaning nozzle 15, and is not obstructed by obstacles such as the rack 4, the conveyor 20, and the rack rail 25. As long as the cleaning water can be sprayed toward the side wall surface 27, the cleaning water may be sprayed in any direction.
