摘要： When tableware is washed and rinsed in a dishwasher using a plurality of washing steps, the tableware is washed within 10 minutes using acid ionized water having a pH value of at most 6.0 and a temperature of at least 40.degree. C. in a first washing step, whereby dirt is made to form cohesion and is prevented from being reattached to the tableware, so that a washing load in the following washing steps is reduced. Furthermore, the tableware is washed for at least 15 minutes with alkaline ionized water having a pH value of at least 8.5 and a temperature of at least 55.degree. C. in at least one of the washing steps, whereby the washing effects on fats and oils, protein and starch are improved. In addition, while the two kinds of ionized water mentioned above are being produced simultaneously, one ionized water produced is supplied to a washing vessel for use in the present washing and the other ionized water produced is supplied to and stored in a water tank for use in the next washing, so that provision of two or more water tanks is not necessary, resulting in reduction in size of dishwashers and in manufacturing cost thereof. Moreover, two kinds of ionized water produced simultaneously are used as washing water without being discarded before use, so that water saving can be achieved.

摘要翻译： 当餐具在洗碗机中洗涤并冲洗时，使用多个洗涤步骤，在第一洗涤步骤中，使用pH值至多为6.0，温度至少为40℃的酸性电离水在10分钟内洗涤餐具 ，由此形成污垢以形成内聚力并防止重新附着到餐具上，从而降低了以下洗涤步骤中的洗涤负荷。 此外，在至少一个洗涤步骤中，将餐具用pH值至少为8.5，温度至少为55℃的碱性离子水洗涤至少15分钟，由此对脂肪和油的洗涤效果 ，蛋白质和淀粉得到改善。 此外，当上述两种离子水同时生产时，所产生的一种电离水被供应到用于本洗涤中的洗涤容器中，并且所产生的其它离子水被供应并储存在水箱中以供使用 在下一次洗涤中，因此不需要提供两个或更多个水箱，导致洗碗机的尺寸减小和制造成本降低。 此外，同时使用的两种电离水被用作洗涤水，而不会在使用前被丢弃，从而可以实现节水。
