However, in general, tableware such as soup plates, bowls, cups, etc., has a large dished portion for food, and when such dishware is submerged in the washing liquid with the dished portion lying down. However, there is a problem in that an air pool is inevitably formed on a part of the coating portion, and only that portion does not come into contact with the cleaning liquid, and a portion that cannot be washed locally is formed. That said, if the dish is placed in the cleaning liquid with the serving part facing upwards, it will be carried to the dish removal part where the food residue attached to the serving part is placed, so it is necessary to wash the hands again. It happened and it was very troublesome.

[0005]

Technical Problem to be Solved The present invention has been made in view of the above-mentioned drawbacks of the "ultrasonic liquid vibration type continuous dishwasher" previously proposed by the present applicant. Even when air is trapped in part of the dish when the food dish is laid face down and submerged in the dish, the dish solution uniformly touches the entire surface of the dish to wash dishes uniformly and efficiently. It is a technical subject to provide a new dishwashing method and a high-performance dishwasher capable of performing the above.

Another technical problem of the present invention is that it is possible to perform a pre-cleaning prior to the main cleaning and also to continuously perform a finishing cleaning also as a disinfection after the main cleaning, which is extremely efficient and hygienic. To provide an effective dishwashing method and a dishwasher effective for it.

Still another technical problem of the present invention is to efficiently wash dishes in a stable posture without causing the dishes to be washed to rattling on the permeable conveyor due to contact resistance with the washing liquid or vibration of the conveyor. It is to provide a high-performance dishwasher that can.

[0008]

The dishwashing process can be carried out efficiently and continuously by contact.

Further, the washing machine of the present invention has a structure in which the dishes to be washed are subjected to shower washing prior to the main washing, and the dishes to be washed after the main washing are subjected to hot water finishing washing also as disinfection. Therefore, it is clean and hygienic.

Further, in the washing machine of the present invention, since a mechanism for performing various washings by stably sandwiching the dishes to be washed between the water-permeable conveyor and the holding conveyor, the contact resistance with the washing liquid and the vibration of the conveyor are adopted. By doing so, the dishes to be washed can be scratched on the permeable conveyer without rattling, damaging the dishes,
Ideally, cleaning can be performed without damage.

As described above, according to the present invention, the unevenness of washing, which can be said to be a difficulty of the previously proposed “ultrasonic liquid shaking type continuous dishwasher” (Japanese Patent Publication No. 3-19775), can be eliminated. The automation of dishwashing has become possible, and it can be said that its industrial utility value is extremely large.
