  When the predetermined cleaning time has elapsed, the rinse water pump 26 is operated, and the rinse water in the rinse water tank 25 is supplied to the rinse nozzles 14A of the upper and lower rinse arms 12, 14 via the rinse pipe 27.

  In the same manner as described above, the rinse water supplied from the rinse pipe 27 is supplied to the inside of the rinse arms 12 and 14 and is ejected by a plurality of rinse nozzles 14A formed on the rinse arms 12 and 14.

  Accordingly, the trays 2 and 3 in the rack 6 accommodated in the cleaning chamber 10 are rinsed by the rinsing water sprayed into the cleaning chamber 10 from the respective rinsing nozzles 14A and so on. After such a rinsing operation is executed for a predetermined time, the control device stops the operation.

  As described above, the trays 2 and 3 accommodated in the rack 6 are vertically or predetermined without overlapping each other by the holding grooves 33 and the support portions 34 of the pair of holding members 32 and 32 provided inside the both ends of the rack 6. Since the cleaning water and the rinsing water discharged into the cleaning chamber 10 can be efficiently sprayed onto the entire surfaces of the trays 2 and 3, the cleaning performance of the trays 2 and 3 is maintained. The rinsing ability can be improved.

  In particular, in this embodiment, the grips 2A and 3A at both ends of the trays 2 and 3 are held by the holding grooves 33 and the support portions 34 of the holding member 32, so that the cleaning water and the rinsing water discharged into the cleaning chamber 10 are used. The trays 2 and 3 fall off from the holding portions such as the holding grooves 33 and the support portions 34 due to the water pressure, and overlap with other trays 2 and 3 and portions where the washing water and the rinsing water do not hit are formed. Accordingly, it is possible to eliminate the disadvantages of cleaning failure and rinsing failure, and cleaning and rinsing can be performed efficiently.

  In the present embodiment, at the edge of the holding groove 33, the support part 35 protruding inward of the rack 6 is provided at the edge facing the support part 34, so that the tray 2 held by the support part 34. 3, even when water pressure or the like is applied, the support portions 34 and the support portions 35 formed on the opposing edge portions can be stably held.

  Further, the pair of holding members 32, 32 provided on the rack 6 are provided on both inner ends of the rack 6, that is, on the opposite vertical walls, in this embodiment, on the inner side of the front wall 6A and the rear wall 6B. Since there are no protrusions or the like on the bottom surface of the rack 6 (in the storage space 30) other than the inner end portions, a relatively large cooking utensil such as a pan, for example, is cleaned. Even in this case, such a cooking utensil can be stored in the rack 6 without any protrusions or the like getting in the way, and it becomes possible to perform cleaning efficiently.

  In this embodiment, the trays 2 and 3 are described as an example of tableware. However, the present invention is not limited to this, and general tableware such as a normal plate or a bowl may be used. Shall.
