Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a method and apparatus for washing tableware, and more specifically, to a method and apparatus for washing tableware, and more specifically, to be able to clean rice grains, etc., which are said to be difficult to remove. The present invention relates to a method for washing tableware and an apparatus therefor.

[Conventional technology]

Dishwashers can be roughly divided into shower type and soaking type. In the shower type, for example, washing water is sprayed onto tableware through a nozzle to wash away dirt adhering to them6.On the other hand, in the soaking type, the tableware is soaked in washing water for a predetermined period of time to remove some of the dirt. After removing the water, spray it with cleaning water and clean it in the same way as in the shower type.

[Problem to be solved by the invention]

Experience has shown that rice grains are the most difficult to fall off. In particular, if the rice grains are stuck to the bowl, they will hardly come off in the shower. This point can be solved with the soaking method, which makes it easier to remove, but it takes a certain amount of time. Additionally, the soaking type is structurally more complex and more expensive than the shower type.

The present invention was made in view of the above-mentioned conventional circumstances, and its first object is to provide a method for washing tableware that is shower-type but has excellent washing ability.

A second object of the present invention is to provide a cleaning device suitable for the cleaning method.
