Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of a dishwasher for washing a dish on which food such as sushi is placed.

[0002]

2. Description of the Related Art Conventionally, a washing apparatus has been used which supplies a dish plate on which foods such as sushi are placed to a washing apparatus to automatically wash the dish.

[0003] In a conventional dish-washing apparatus, a transfer section capable of transporting a dish is provided in a housing having a dish opening and a discharge opening formed on an upper surface thereof so as to extend from the loading opening to the discharge opening. Below the input port and the discharge port, guide cylinders through which tableware dishes can be inserted are provided so as to extend toward the transport unit.

[0004] The tableware dish guided from the input port to the transport section via the guide tube is washed while moving through the transport section,
Furthermore, after being drained by the air injected from the air injection nozzle, it is configured to be discharged from the discharge port.

However, in recent years, there has been a demand for shortening the washing time of dish plates in order to increase the frequency of reusing dish plates. However, simply increasing the speed of the transport unit of the cleaning apparatus has a problem that the dishwashed with the cleaning liquid during the moving process cannot be dried in time by the air jetted from the air jet nozzle.

Therefore, a method of drying the dish plate after washing in a short time by increasing the air volume of the air injected from the air injection nozzle is adopted.

[0007]

However, well-known support portions for loading and supporting the dishes in a multiplex manner are arranged in the middle of the guide tubes of the input port and the discharge port communicating with the outside. As a result, a plurality of dish plates are accommodated in a stacked state in the guide cylinder, and the input port and the discharge port are closed by the dish plates to increase the air injection amount of the air injection nozzle in the closed casing. Then, the internal pressure increases.

For this reason, there is a problem that when the number of dishes in the inlet or the outlet is reduced, the plate is blown up by the internal wind pressure and causes troubles when the tray is put into or discharged from the transport section.

The present invention has been made in view of such a problem, and even if the flow rate is doubled with the speeding up of washing, the input and discharge of the dish to the washing apparatus is affected by the internal wind pressure. It is an object of the present invention to provide a dishwashing apparatus that can be smoothly performed without using a dishwasher.

[0010]
