After arriving at the school, the tableware basket 1 is taken out from the container 2, meals are arranged in the classroom and cafeteria, and distributed to the students in the school lunch room. After the meal is finished, the dirty tableware used as shown on the upper left side of the drawing is stored in the tableware basket 1 again, and the tableware basket is stored in the container 2 and transferred to the intensive cleaning place.

The dishes are taken out of the transferred container 2, and each dish is placed on a suitable conveyor of the fully automatic dishwashing system and apparatus for washing, and then the container is also separately washed and dried to remove the washed dishes. The container is stored in the container 2 from the conveyer, transferred to the disinfection chamber 4, and the fully disinfected container is transported from the centralized cleaning chamber to the outside to repeat the cycle. Dirty dishes after eating from outside are stored in the moving container 2 and carried into the entrance of the fully automatic dishwashing system and apparatus.

FIG. 2 is an explanatory perspective view of the fully automatic dishwashing system and apparatus of the present invention. This fully automatic dishwashing system and the arrangement of the device 3 are centered on the container washing section 5,
There is a can cleaning machine 6 and a tray cleaning machine 7 in the upper part, and a dish cleaning machine 8 and a soup bowl cleaning machine 9 are arranged in a plurality of rows in the lower part. The container 2 for transportation moved to the entrance is the container cleaning machine 5.
The tableware that has been washed in 1. is again stored in the movable container 2 and carried into the disinfection chamber, which is a centralized processing system and its equipment at one location.

The container 2 carried into the entrance of the fully automatic dishwasher system and apparatus 3 is opened at the front and rear surfaces thereof, and the can 10 and the tempura pan 11 are respectively provided with a single or a plurality of rows of entrances. It is placed on the conveyor 12 and moves. In this case the conveyor 12 at the entrance
Is usually separated from the food can conveyor 13 and the tempura conveyor 14.

The soup ladle container is usually put in a tempura container and returned. The food can 10 and the frying pan 11 move on the respective conveyors, and the food can 10 moves to the food can lowering washer 15. Here, the residual food is dropped with a shower, then the inside is washed down with a brush, and placed on a conveyor connected to the can cleaning machine 6 for washing. In addition, a soup ladle, a lid, a net, etc. are put in the tempura tray, and the outer lid, the inner lid, and the soup ladle are placed on the washing conveyer while the main body of the can is being washed down. However, the washing of the lid of the food can is branched at a branch point 39 from the middle of the food can conveyer and merges later.

In the tempura tray conveyer 14, the lid, mesh and main body of the tempura tray 11 are placed on a conveyor connected to the washing machine. If the main body contains a soup ladle basket, remove it and place it on the washer conveyor. The can cleaning machine 6 is composed of a single tank and a plurality of cleaning tanks 18 and a single and a plurality of layers of rinsing tanks 19, in which strong alkaline water is overheated (set temperature) and pumped by a circulation pump. Then, spray with a plurality of shower nozzles to clean. After the rinsing tank, strong acid water is sprayed with a shower nozzle, and a finishing shower with a hot water temperature is applied in front of the outlet for cleaning.

After the washing is completed, the food can 10 and the tempura container 11 are placed on a stand 16 connected to a moving conveyor, and can be easily moved by using a caster at the bottom outside the apparatus. It is placed on a movable rack 17 that can be used, and is carried into the disinfection chamber and is disinfected and dried. As will be described later, after washing other trays, dishes, soup bowls, etc., they are loaded on a moving container via a conveyor, carried into a disinfection chamber, and disinfected and dried.

A tray cleaning machine 7 is installed inside the food can cleaning machine 6 for cleaning food cans and tempura containers, and its structure is the tray basket of the tray used, or from the table basket. The removed soup receiving pan is washed by placing this basket on the entrance belt conveyor 12. That is, since the dish basket does not have a soup pan, the soup pan is removed from the dish basket at the entrance, and after cleaning is completed, the soup pan is set in the dish basket.

The tray moves on the tray conveyor 20 for cleaning the tray and moves to the tray cleaning machine 7.
The arrangement of the tray washer and its operation are exactly the same as those of the lower plate and soup bowl washer. And first of all, the first tray cleaning machine
Move to cleaning tank. In the first cleaning tank 21, the tray is spray-cleaned to clean the remaining residue, and the remaining residue is automatically carried out from the outlet installed at the bottom of the cleaning tank.
After passing through the first cleaning tank 21, it moves to the second cleaning tank 22. The second cleaning tank 22 is a cleaning tank by jetting, in which strong alkaline water is sprayed from above, below, left and right in hot water suitable for cleaning to perform cleaning.

The tray moved to the next tank is ultrasonically cleaned in the tank. The inside of the tank is used as warm water for cleaning, and this tank is cleaned with strong alkaline water by ultrasonic waves at a frequency suitable for cleaning. The length of the tank is
It is determined by matching the frequency of ultrasonic waves and taking into account the degree of warm water. Most of the dirt is removed in the ultrasonic cleaning tank.

The tray that has passed through the ultrasonic bath can be sent to the third cleaning bath 25 through the next shower section 24. When you go up, apply a shower from the top, and if there is still dirt on the dishes, remove it well and send it to the third washing tank 25. The third cleaning tank 25 is followed by the fourth cleaning tank 26. This is a rinsing tank, and rinsing is performed by jetting in these two tanks to perform complete rinsing.

Further, subsequently to this tank, strong acidic water is sprayed to sterilize and disinfect, and a finishing shower with hot water is applied in front of the exit, after which it is automatically placed on the exit conveyor 28. It is carried out and later loaded on the container 2 and carried out to the outside. Next, as for the dish soup bowl washing machine 8 and the soup bowl washing machine 9, the construction thereof is the same as that of the tray washing machine.

However, when the position of the switch is confirmed by the limit switch 29 at the place where it moves to the washing machine and enters the washing machine, it is carried into the washing machine, and the position is confirmed. Insufficient cleaning due to the above is eliminated. In addition, each washing machine is provided with an independent control panel 30 for managing each washing machine at the final finishing portion of the apparatus, and operates the washing machine independently from a central control panel 31 described later. You can control.

Since the central part of the device is the container part which is used for cleaning the container and is located in the central part of the system, a centralized control panel 31 is provided here to control and manage the device. To do. The container washing machine 5 is correctly introduced into the container by the container introducing part 32, first performs vertical and horizontal jet cleaning 33, and then after the jet cleaning 33, removes water droplets with a blower 36.
After cleaning the container, place it between the exit conveyors.

In the vicinity of the left side surface of the container cleaning machine 5, a slight amount of salt is added to the tap water by the ion generator 34 and electrolyzed to generate strong alkaline water and strong acidic water. The strong alkaline water tank tank 35 and the strongly acidic water tank tank 37 are stored in the vicinity to prepare for cleaning and sterilization. A centralized control panel 15 is located near the entrance of the container washing machine to control the system as a whole. The control is usually microcomputer control or sequence control. Centrally manages all the work such as water filling work of each washing machine, temperature control system such as humidity rise control, and speed control of equipment.

Since the device of the present invention has the above-mentioned structure, when it is used, it is as follows. The tableware that has been washed by the apparatus of the present invention is put into a tableware basket and stored in a container at the exit of the conveyor, and is further completely sterilized in a disinfection room in the same room or a separate room. , It is carried out to the outside, and the dishes are taken out from the tableware basket outside, the food is placed on the tableware, and the meal is carried out. The system is repeated.

The apparatus of the present invention has a container washing machine at the center and other washing machines above and below it, but the construction of the apparatus is not necessarily limited to this. The conveyor is driven by a motor, The speed is controlled by the command. In the tableware basket that is conveyed from the outside, a soup pan is inserted at the bottom of the tableware basket so that the leftovers of the tableware do not drip when it is placed on the conveyor. Remove from the basket.

Further, strong alkaline water and strong acidic water are usually electrolyzed by adding a trace amount of salt to tap water to generate a strong alkaline water and a strongly acidic water. After use, the water returns to normal water, which does not affect the human body and reduces running costs. Although a considerable amount of water or hot water is used in the present invention, for example, the water is reprocessed after the injection, which is part of the rationalization. When spraying with a shower nozzle, steam is usually used for temperature control in the tank, but an electric heater or a gas booster may be used.

Each of the first, second, third and fourth tanks usually has a tank for heating the accumulated water and injecting hot water from a shower nozzle with a pump. And it circulates. It is different for finishing. This device has a so-called double or triple cleaning system, and since various cleaning systems are adopted, it was confirmed that all the rice grains that had adhered to the dishes were washed. ing. or,
The disinfection of the final step, which is separately performed, is performed with hot air, but this step may be a separate room depending on the size of the room in which the device is placed, but there is no problem in the work.
