WASHING MACHINE

To improve washing function of a washing machine that intermittently washes a bucket that receives dust falling from a belt conveyer in comparison with a prior art.SOLUTION: During washing with intermittently water supply, adhesion force is generated between dust and a bucket in a drying process while no water is supplied, so it is effective to set a time for reducing the adhesion force with a small amount of water at the beginning of washing and thereafter wash off dust with a large amount of water. Thus in this invention, in a washing machine that washes a bucket by intermittently supplying water at an upper part of the bucket inclined for receiving dust falling from a belt conveyer, the amount of water for washing in the first half is smaller than the amount of water for washing in the second half.SELECTED DRAWING: Figure 5 【課題】ベルトコンベアから落下する粉塵を受け止める樋を間欠的に洗浄する洗浄装置の洗浄能力を従来に比べて向上させる。【解決手段】間欠給水洗浄では、給水しない間の乾燥過程において粉塵と樋の間に付着力が生じることから、洗浄初期に少量の水で付着力を緩和する時間を設け、その後に多量の水で粉塵を押し流すのが有効である。そのため、本発明では、ベルトコンベアから落下する粉塵を受け止める傾斜させた樋の上部に間欠的に水を供給して樋を洗浄する洗浄装置において、樋を洗浄する水の量が、洗浄前半の水量＜洗浄後半の水量とされている。【選択図】図５
