DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a basket-like container which is installed in a school or a lunch center, for example, and stores a large amount of dishes, trays, spoons, cans, and other dishes contaminated with food residues. The present invention relates to a dishwashing apparatus for continuously sending dishes to a plurality of washing tanks and washing dishes in the washing tanks.

[0002]

2. Description of the Related Art Conventionally, in a dishwashing apparatus of this type, as shown in FIG. 12, for example, a receiving table is formed by a conveyor 1 in which a net-like endless belt 1a is stretched between rollers 1b. On top of the conveyor 1, a basket-like container 2 accommodating tableware contaminated with food residues is placed so that it can be transported horizontally, and the conveyor 1 has, for example, an injection nozzle 3a inside in order from the upper side to the lower side. There is a configuration in which a plurality of cleaning tanks 3 having different cleaning modes are arranged so as to communicate with each other.

[0003] During washing, the tableware is continuously conveyed together with the containers 2 by the conveyor 1, and sequentially in each washing tank 3, for example, lower washing hot water, alkaline washing water, acidic washing water, finishing hot water. Were respectively sprayed from the spray nozzles 3a to wash the dishes.

[0004] Conventionally, among other dishwashing apparatuses, there is a round type in which a conveyor 1 for transporting dishes is bent and arranged as shown in FIG. 13, for example. This cleaning device covers the conveyor 1 with a hood 5 except for a conveyer inlet a and an outlet b which are separated by a guide 4 on the left side in the figure, and a jet nozzle 6a is provided in the hood.
The main cleaning tank 6 and the finishing cleaning tank 7 having different cleaning modes having 7a are provided so as to communicate with each other.

At the time of washing, a basket-like container (not shown) accommodating tableware is placed on the conveyor 1 from the transfer inlet a side and continuously conveyed. Water was sprayed from the spray nozzle 6a, and subsequently, warm water for finishing was sprayed from the spray nozzle 7a in the finish washing tank 7 to wash dishes.

[0006]

However, in the conventional dishwashing apparatus as described above, each of them becomes horizontally long by the number of different washing layers provided, and if each washing section is lengthened, the same is required.

Then, the tableware 49 is moved to the lower washing tank 15 together with the container 50, and the hot water in the lower washing tank 25 is injected from the injection nozzle 29 by the pump 28 for 30 seconds, for example, to perform the lower washing. In the lower washing, large food residues adhering to the tableware 49 are physically washed away and the strainer 24 is removed.
Will be collected.

After the lower washing, the support shaft 11 is rotationally driven again to rotate the partition plate 12 together with the cradle 20 by 90 degrees.
The container 9 is moved to the main cleaning tank 16 together with the container 50, and the main cleaning is chemically performed by injecting, for example, 30 seconds of detergent-containing hot water in the main washing tank 30 from the injection nozzle 34 by the pump 33.

After the main cleaning, similarly, the partition plate 12 is rotated together with the cradle 20 by 90 degrees, the tableware 49 is moved together with the container 50 to the finish cleaning tank 17, and the pump 36 is used to move the tableware 49 from the injection nozzle 37 into the finish tank 35. Hot water is then sprayed, for example, for 20 seconds.

In the finish washing tank 17, after the hot water is injected, the finish shower 40 shown in FIG.
And then wash the tableware 49 again.

After the finish washing, the partition plate 12 is similarly placed on the receiving table 2.
It rotates together with 0 by 90 degrees, sends the tableware 49 together with the container 50, and returns it to the tableware chamber 14. And the automatic door 23
Is opened, and the containers 50 are sequentially taken out together with the tableware 49. Thereafter, the container 50 in which the next tableware is set is put into the tableware loading / unloading chamber 14 and set.

In this manner, the partition plate 12 is moved 90 times at each partition position between the tableware loading / unloading chamber 14 and each of the washing tanks 15-17.
It rotates intermittently every time, and every time it
While separating between the washing tanks 15 to 17 with the partition plate 12,
The tableware 49 is continuously transported together with the container 50. then,
The containers 50 in which the tableware 49 is set are sequentially set two by two in the tableware receiving / storing chamber 14, and these are set around the support shaft 11,
The cleaning is performed by sequentially feeding the lower cleaning tank 15, the main cleaning tank 16, and the finish cleaning tank 17. In this way, the dishes are taken out of the tableware receiving / storing chamber 14 in order from the ones having been washed.

In the above-described cleaning apparatus, the receiving table 20 is intermittently rotated together with the partition plate 12. However, in the present invention, although not shown, for example, while the pedestal is fixedly supported, the tableware is rotated and the tableware placed on the pedestal is pushed around with the container so as to slide on the pedestal. It is also possible to adopt a configuration for carrying.

Further, in the above-described cleaning device, the partition plate 12 attached to the support shaft 11 is driven by the drive motor M to rotate intermittently. However, in the present invention, though not shown, a partition plate may be provided on an outer peripheral wall provided in the cleaning tank, and the outer peripheral wall may be driven by driving means to intermittently rotate the partition plate.

Further, in the above-described cleaning apparatus, the drive motor M is installed below the apparatus main body case 10, but, for example, as shown in FIG. 12 may be configured to rotate intermittently.

Further, in the above-described cleaning apparatus, for example, as shown in FIG. 8A, the automatic door 23 can be formed in an angle plate shape. Further, as shown in FIG. 3B, the partition plate 12 can be assembled to the support shaft 11 in an X shape when stopped at each partition position.

Further, in the above-described washing apparatus, for example, as shown in FIG. 9, a part of the receiving table 20 can be freely put in and taken out of the table taking-in / out chamber 14.

In this case, for example, as shown in FIG. 10 (a), a U-shaped slide frame 55 is provided to face each other, and a plurality of rollers 56 are rotatably mounted in the slide frame 55, respectively. Sunoko 57 on top
And can be put in and taken out. As shown in FIG. 10 (b), for example, the saw blade 57 is formed by assembling a rectangular frame member 57a with an elongated plate member 57b spanned at intervals.

Further, in the above-described cleaning apparatus, as shown in FIG. 11, for example, a hinge 60 is used, and the apparatus main body case 10 is provided so as to be openable and closable so that the cleaning tank can be cleaned and maintained. It can also be made easier. Reference numeral 59 denotes a moving caster.

In the cleaning apparatus described above, the lower cleaning tank 1
5 is provided with a strainer 24, but may be provided in another cleaning tank.

[0047]

Therefore, according to the present invention, while the cleaning tanks are sequentially arranged around the axis, a partition plate for separating the cleaning tanks around the axis above the receiving table is arranged radially. In order to be able to rotate integrally and to intermittently rotate the partition plate by a fixed angle at each partition position between the cleaning tanks by transmitting drive to the partition plates, the whole apparatus is made compact. It can be installed with plenty of room even in tight places such as schools.

Further, the partition plate can prevent adverse effects such as mixing of washing water and sewage jetted between the adjacent washing tanks, thereby lowering the washing effect peculiar to each washing layer.
