- dissolved hydrogen concentration is set. Even when the electrolysis current is increased to increase the pH value, the pH value of the electrolyzed water is prevented from excessively rising. Thereby, it is possible to generate electrolyzed water having a high dissolved hydrogen concentration at a pH value suitable for drinking.
- 1st electric power feeding bodies 31 and 41 are applied as an anode electric power feeding body, ie, when 1st pole chamber 30A and 40A are applied as an anode chamber, 1st pole chamber 30A and 1st pole chamber 40A become.
- the first water channel 51 may be connected in parallel. In this case, oxygen gas generated in the first electrode chamber 30A does not flow into the first electrode chamber 40A, so that water is sufficiently supplied also to the surface of the first power feeder 41. Therefore, electrolysis is efficiently performed in the electrolysis chamber 40, and the dissolved hydrogen concentration can be increased.
- the electrolysis chamber 30 is disposed on the upstream side of the second water channel 52, and the electrolysis chamber 40 is disposed on the downstream side of the second water channel 52. That is, the second polar chamber 30B that generates neutral electrolyzed water is arranged on the upstream side of the second water channel 52, and the second polar chamber 40B that generates alkaline electrolyzed water is on the downstream side of the second water channel 52. It is arranged. Thereby, since deposition of scale does not occur in the second polar chamber 30B on the upstream side, scale adhesion is suppressed in the second polar chamber 30B and the second water channel 52. In the second electrode chamber on the upstream side, neutral electrolyzed water in which hydrogen gas generated by water electrolysis is dissolved is generated.
- the dissolved hydrogen concentration is increased by electrolysis of water, and reduced alkaline electrolyzed water is generated.
- the scale is deposited as a result of electrolysis, but the area where the scale adheres is limited to the water channel further downstream than the second polar chamber 40B. It becomes easy.
- scale measures can be easily taken by setting the cross-sectional area of the water channel further downstream from the second pole chamber 40B. Therefore, it is possible to generate “electrolytic hydrogen water” having a high dissolved hydrogen concentration at a pH value suitable for drinking while suppressing adhesion of scale.
- the direction of water flow in the first electrode chambers 30A and 40A is the same as indicated by arrows 30X and 40X.
- the water flow directions 30X and 40X in the first polar chambers 30A and 40A are vertical directions from the lower end portions to the upper end portions of the first polar chambers 30A and 40A.
- the directions 30X and 40X of the water flow in the first electrode chambers 30A and 40A coincide with the moving direction of the oxygen gas generated in the first electrode chambers 30A and 40A, so that the oxygen gas is efficiently contained in the first electrode chamber 30A and 40A. It is discharged from 30A and 40A.
- the oxygen gas generated in the first electrode chambers 30 ⁇ / b> A and 40 ⁇ / b> A stays on the surfaces of the first power feeding bodies 31 and 41. Accordingly, water is sufficiently supplied also to the surfaces of the first power feeding bodies 31 and 41, and electrolysis is efficiently performed in the electrolysis chambers 30 and 40, so that the dissolved hydrogen concentration can be increased.
- the direction of the water flow in the second electrode chambers 30B and 40B is the same as indicated by arrows 30Y and 40Y.
- the directions 30Y and 40Y of the water flow in the second polar chambers 30B and 40B are vertical directions from the lower end portions to the upper end portions of the second polar chambers 30B and 40B. For this reason, since the directions 30Y and 40Y of the water flow in the second polar chambers 30B and 40B coincide with the moving direction of the hydrogen gas generated in the second polar chambers 30B and 40B, the hydrogen gas efficiently flows into the second polar chamber. It is discharged from 30B and 40B.
- the hydrogen gas generated in the second electrode chambers 30B and 40B is suppressed from staying on the surfaces of the second power feeding bodies 32 and 42. Therefore, water is sufficiently supplied also to the surfaces of the second power feeders 32 and 42, and electrolysis is efficiently performed in the electrolysis chambers 30 and 40, so that the dissolved hydrogen concentration can be increased.
- the electrolysis chambers 30 and 40 are juxtaposed in a direction perpendicular to the water flow directions 30X, 40X, 30Y and 40Y. In such a form, it becomes easy to reduce the height by suppressing the height of the electrolyzed water generating apparatus 1.

- configurations not described below are the same as those of the electrolyzed water generating apparatus 1.
- the electrolysis chambers 30 and 40 are arranged in the vertical direction, the ground contact area of the electrolyzed water generating apparatus 1A can be suppressed, and the degree of freedom of installation in a small kitchen or the like is increased. Enhanced.
- the electrolyzed water generating apparatus 1 includes at least a plurality of electrolysis chambers 30, 40,... For electrolyzing water, and each electrolysis chamber 30, 40,. ... and the second power feeding bodies 32, 42, ..., and the electrolysis chambers 30, 40, ..., the first electrode chambers 30A, 40A, ... on the side of the first power feeding bodies 31, 41, ..., and the second , Which are divided into second electrode chambers 30B, 40B, ... on the side of the power feeding bodies 32, 42, ..., are arranged, and each electrolysis chamber 30, 40, ...
- each first electrode chamber 30A, 40A,... are connected by a first water channel 51 that communicates serially or in parallel with each other, and a second water channel 52 that communicates each of the second electrode chambers 30B and 40B in series, and is located on the upstream side of the second water channel 52.
- first water channel 51 that communicates serially or in parallel with each other
- second water channel 52 that communicates each of the second electrode chambers 30B and 40B in series, and is located on the upstream side of the second water channel 52.
- neutral electrolyzed water is generated, and in the second electrode chamber 40B on the downstream side of the second water channel 52, It may be composed as alkaline resistance of the electrolytic water is generated.
- the electrolysis chamber 30 is applied to the most upstream electrolysis chamber, and the electrolysis chamber 40 is applied to the most downstream electrolysis chamber.
- a structure equivalent to the electrolysis chamber 30 or the electrolysis chamber 40 can be applied to the electrolysis chamber disposed between the most upstream electrolysis chamber and the most downstream electrolysis chamber. In this case, it is desirable to arrange each electrolysis chamber so that the electrolysis chamber 30 in which neutral electrolyzed water is generated is not located downstream of the electrolysis chamber 40 in which alkaline electrolyzed water is generated.

Abstract
L'invention concerne un dispositif de génération d'eau électrolysée (1) comprenant une pluralité de chambres électrolytiques (30, 40, …) pour l'électrolyse de l'eau. Dans les chambres électrolytiques (30, 40, …) sont agencés des premiers dispositifs d'alimentation électrique (31, 41, …) et des seconds dispositifs d'alimentation électrique (32, 42, …) se faisant face, et des diaphragmes (33, 43, …) divisant les chambres électrolytiques (30, 40, …) en premières chambres d'électrode (30A, 40A, …) et en secondes chambres d'électrodes (30B, 40B, …). Une membrane polymère solide est utilisée pour le diaphragme (33). Les chambres électrolytiques (30, 40, …) sont reliées par un premier trajet d'eau (51) qui relie les premières chambres d'électrode (30A, 40A, …) en série ou en parallèle et un second trajet d'eau (52) qui relie en série les secondes chambres d'électrode (30B, 40B). De l'eau électrolysée neutre est générée dans la seconde chambre d'électrode (30B) sur le côté amont du second trajet d'eau (52), et de l'eau électrolysée alcaline est générée dans la seconde chambre d'électrode (40B) sur le côté aval.
