Article washing device

Abstract

A dishwasher washes off leftovers adhering to tableware by washing water spouted toward the interior of a shower sink (12) and washes away the leftovers falling down into the shower sink (12) by the washing water. The cross-sectional shape of the shower sink (12) has a bottom wall (12a) of lar ge curvature, a first lateral wall (12b) rising substantially upright from one end of the bottom wall (12a), and a second lateral wall (12c) having a curvature smaller than that of the bottom wall (12a) and rising from the oth er end of the bottom wall (12a). The flow channel cross-sectional area of the bottom wall (12a) is smaller than that of the shower sink (12) having a quadrangular or circular cross-section; therefore, even if water is saved by reducing the flow rate of washing water, it is possible to increase the flow rate of washing water flowing in the bottom wall (12a) to effectively wash away the leftovers.

Description

technical field [0001] The present invention relates to an article washing device for washing dirt adhering to articles with washing water sprayed toward the inside of a washing tank, and washing away dirt falling inside the washing tank with the washing water. Background technique [0002] In cafeterias where many people dine, use the flush sink to wash off leftovers left on tableware after meals. The cross section of the conventional washing tank is formed into a quadrangular flow tank shape, and the leftovers attached to the tableware are washed with the washing water sprayed from the nozzle on the upper part of the side wall on the front side, and the leftovers and the flow are rinsed. The wash water on the bottom wall of the water tank flows away together. [0003] And, according to Japanese Patent Application Publication No. 56-46039 and Japanese Patent Application Publication No. 5-79283, the following technology has been known. By using a so-called elliptical pipe w...

Problems solved by technology

[0004] However, the conventional flushing tank has a square cross section, so it is difficult to increase the flow rate of the washing water flowing through the bottom wall, and there is a problem that leftovers will accumulate on the bottom wall if a large amount of washing water is not flowed.

In this way, if the leftovers are piled up on the bottom wall of the flushing tank, it will bring discomfort to the user; at the same time, if the leftovers are to be prevented from piling up, a large amount of washing water needs to flow through, and there is a problem of waste.
