<First Embodiment>
FIG. 1 is an explanatory diagram showing a cleaning system according to the first embodiment of the present invention.

  The cleaning system 1 includes an alkali ion water generation unit 10, an alkali ion water generation medium supply unit 20 that supplies the alkali ion water generation medium 21 to the alkali ion water generation unit 10, and alkali ions generated by the alkali ion water generation unit. An alkaline ionized water storage unit 30 for storing water and a cleaning tank 100 for cleaning a cleaning target are provided. The cleaning tank 100 includes a drum tank 200.

  Water is supplied to the drum tank 200 of the cleaning tank 100 through the first pipe 50. Water is supplied to the alkaline ionized water generator 10 through the second pipe 51. The alkaline ionized water generation unit 10 is also supplied with the alkaline ionized water generation medium 21 from the alkaline ionized water generation medium supply unit 20. Therefore, the alkali ion water generation medium supply unit 20 includes a plurality of alkali ion water generation media 21. The alkaline ionized water production medium 21 reacts with water and changes to alkaline ionized water having a pH of 12.5 or higher, for example.

  The alkali ion water produced | generated in the alkali ion water production | generation part 10 is produced | generated over time. For this reason, the alkaline ionized water storage unit 30 stores the generated alkaline ionized water in preparation for use in the cleaning tank 100.

  Alkaline ion water is supplied from the alkali ion water storage unit 30 to the drum tank 200 of the cleaning tank 100 through the third pipe 52. The supply of alkaline ionized water is performed by a pump (not shown). The third pipe 52 is provided with an adjustment valve 40. The adjustment valve 40 adjusts the amount of alkaline ionized water from the alkaline ionized water storage unit 30 to the drum tank 200. Thereby, the ratio of the water supply amount from the first pipe 50 and the water supply amount of the alkaline ionized water from the third pipe 52 is adjusted. By adjusting the ratio of the amount of water and alkaline ionized water, cleaning can be performed at a hydrogen ion concentration suitable for the object to be cleaned, such as clothes, in the cleaning tank.

  The ratio between the amount of water supplied from the first pipe 50 and the amount of supplied alkaline ion water from the third pipe 52 is preferably 5: 1. The water from the first pipe 50 has a pH of about 7, and the alkaline ionized water from the third pipe 52 has a pH of about 12.5. By supplying these water and alkaline ionized water 5 to 1 to the washing tank 100, alkaline ionized water having a pH of about 12 is obtained, and clothes and the like are washed without detergent.

  As will be described later, the alkali ion water generation medium supply unit 20 includes a timer, and automatically supplies the alkali ion water generation medium 21 to the alkali ion water generation unit 10 according to the timer. Good. Further, the alkali ion water generating medium supply unit 20 is configured to supply the alkali ion water generating medium 21 to the alkali ion water generating unit 10 according to the amount of alkaline ion water stored in the alkali ion water storing unit 30. Also good. In this case, the alkali ion water storage unit 30 is provided with detection means for detecting the storage amount of the alkali ion water, and the detected information is sent to the alkali ion water generation medium supply unit 20.

  The water supplied to the alkaline ion water generator 10 may be water distributed from the first pipe 50.

  The route supplied to the drum tank 200 of the cleaning tank 100 via the alkaline ionized water generation unit 10 and the alkaline ionized water storage unit 30 is a route in which a detergent is mixed with hot water and sent to the cleaning tank 100 in a normal cleaning system. is there. Accordingly, in a normal cleaning system, clothes and the like can be washed without using a detergent by attaching the alkali ion water generation unit 10 and the alkali ion water storage unit 30 provided with the alkali ion water generation medium supply unit 20. Can do. Moreover, you may make it comprise the alkali ion water production | generation part 10 and the alkali ion water storage part 30 provided with the alkali ion water production | generation medium supply part 20 as one unit, and to attach.

  In addition, the alkaline ionized water production | generation medium 21 can use the electrolytic auxiliary agent shape | molded in the solid form which consists of potassium carbonate, for example. When potassium carbonate is used, it is possible to generate about 15 liters of 12.5 pH alkaline ionized water per hour. The amount of potassium carbonate supplied to the alkaline ionized water generation unit 10 is adjusted according to the amount of alkaline ionized water required in the cleaning tank 100, the amount stored in the alkaline ionized water storage unit 30, and the like.

  Further, in the present embodiment, the alkali ion water generating medium 21 molded in a solid form is used. However, it may be in the form of powder, and depending on the amount of the alkali ion water to be generated or stored, the alkali ion water is generated. The amount of potassium carbonate supplied to the unit 10 may be adjusted.

  Moreover, in this invention, it wash | cleans with the alkaline ionized water suitable for the washing | cleaning defined as strong alkaline ionized water exceeding pH10. Furthermore, in this invention, it is preferable to wash | clean with the strong alkaline ionized water exceeding pH12 which also has a microbe elimination effect | action. Since dirt on clothes, etc. is acidic, the more alkaline the water is, the more dirt is removed. Particularly, alkaline ionized water having a pH of 12 or more decomposes and cleans oil stains and tobacco dust.

  Since alkaline ionized water does not use a synthetic surfactant, it can be rinsed simultaneously with washing without foaming. For this reason, it leads to significant water saving and also to cost reduction. In addition, since no detergent is used, there is no color and no odor, and removal of bacteria by the sterilization effect with alkaline ionized water leads to a deodorization effect.

Digitization is performed by f (d, v, s, mode) (step ST301).

  The numerical value of the function f (d, v, s, mode) is compared with the predetermined value α (step ST302). If the numerical value of the function f (d, v, s, mode) is equal to or greater than the predetermined value α (Yes in step ST302), it is determined that it is necessary to wash more strongly than usual, and the amount of alkaline ionized water becomes larger than usual.
