Dishwasher

A dishwasher, comprising:

• an electrolytic washing water adjusting portion for electrolyzing water supplied from a water supply to produce acid ionized water and alkaline ionized water;
• a washing vessel for accommodating tableware and washing said tableware using supplied washing water;
• and
• a discharging portion for discharging said washing water after being used for said washing from said washing vessel, wherein
• when washing and rinsing of said tableware are carried out in a plurality of washing steps each including said washing and said discharging, and at least one of said plurality of washing steps uses said alkaline ionized water with a PH value of at least 8.5 and having a temperature of at least 55.degree. C. as said washing water.

A dishwasher, comprising:

• an ionized water producing portion for electrolyzing water supplied from a water supply to produce acid ionized water and alkaline ionized water;
• a washing vessel for accommodating tableware and washing said tableware using supplied washing water;
• and
• a discharging portion for discharging said washing water after being used for said washing from said washing vessel, wherein
• when washing and rinsing of said tableware are carried out in a plurality of washing steps each including said washing and said discharging, said washing step for said rinsing uses said acid ionized water having a PH value not more than 6 and a temperature of at least 60.degree. C. as said washing water.

A dishwasher for washing and rinsing tableware in a plural number of steps, comprising:

• means for simultaneously producing from water supplied from a water supply a prescribed amount of alkaline ionized water and a prescribed amount of acid ionized water which are required for each of said plurality of steps;
• and
• means for carrying out each of said plurality of steps using, in each step, any one of water supplied from said water supply, said prescribed amount of alkaline ionized water and said prescribed amount of acid ionized water which are produced simultaneously, wherein
• in said plurality of steps, the number of steps using washing water of a same property which are successively carried out by said step carrying out means is at most two for each of said alkaline ionized water and said acid ionized water.

A dishwasher, comprising:

• producing means for producing two kinds of ionized water from water supplied from a water supply;
• storing means for storing supplied said ionized water;
• and
• washing means for washing tableware in a plurality of washing steps using supplied said ionized water, wherein
• said producing means includes
• first supplying means for supplying one of said produced two kinds of ionized water to said washing means for use in present said washing step while said ionized water is being produced, and
• second supplying means for supplying another of said produced two kinds of ionized water to said storing means for use in next said washing step while said ionized water is being produced, and
• said storing means includes
• third supplying means for supplying stored said another ionized water to said washing means when said next washing step is started.
