Abstract: A cooling garment cooling device includes: a water delivery hose with a cooling water supply portion and cooling water branch portion; a pump supplying cooling water from the cooling water supply portion toward the cooling water branch portion; and plural branched water hoses having a first end-side water supply portion and second end-side water supply portion coupled to the cooling water branch portion. A portion of the branched water hoses between the first end-side water supply portion and second end-side water supply portion serves as a water outlet portion. Each branched water hose diameter is smaller than the water delivery hose diameter. The outer peripheral portion of the water outlet portion of each branched water hose orthogonal to the longitudinal direction of the branched water hose has plural water passage holes with opening areas smaller than those of the first end-side water supply portion and second end-side water supply portion.

Abstract: In a batch type electrolyzed water producing method, a first run of electrolysis is carried out, and electrolyzed water is discharged. Thereafter, before a next run of electrolysis is carried out, the polarity of a DC power source connected to the electrode plates is reversed. Thus, the electrode plate which has served as a cathode plate in the last run of electrolysis is converted into an anode plate and therefore, deposits accumulated on the electrode plate are ionized and dissolved into the subject water.
