Abstract

Electrolytic liquid generating device ( 1 ) includes laminated body ( 41 ) in which conductive film ( 46 ) is laminated to be interposed between mutually adjacent electrodes ( 44, 45 ), and electrolytic part ( 40 ) which electrolyzes liquid. Furthermore, electrolytic liquid generating device ( 1 ) includes a passage having inflow port ( 71 ) in which liquid to be provided to electrolytic part ( 40 ) flows and outflow port ( 72 ) from which electrolytic liquid generated in electrolytic part ( 40 ) flows out. The passage is formed such that liquid flowing direction (X) crosses laminated direction (Z) of laminated body ( 41 ).

First claim

1 . An electrolytic liquid generating device comprising:
an electrolytic part having a laminated body in which a conductive film is laminated to be interposed between mutually adjacent electrodes, the electrolytic part being configured to electrolyze liquid, and a passage having an inflow port in which liquid to be provided to the electrolytic part flows and an outflow port from which electrolytic liquid generated in the electrolytic part flows out, the passage being formed such that a liquid flowing direction crosses a laminated direction of the laminated body, wherein a groove part opened to the passage is formed in the laminated body, at least a part of a boundary surface between the conductive film and the electrodes being exposed to the groove part, a crossing surface crossing an orthogonal surface orthogonal to the liquid flowing direction is formed on at least a part of a side surface of the groove part at a downstream side in the liquid flowing direction among the side surfaces of the groove part, and when seen in the laminated direction, the crossing surface is formed such that an edge of the groove part at a bottom surface side in the crossing surface is disposed in a region, which includes a boundary line, defined by an edge of the groove part at an opening side.

2 . The electrolytic liquid generating device according to claim 1 , wherein, when seen in the laminated direction, the crossing surface is formed such that a line depicted by the edge of the groove part at the opening side in the crossing surface is extended in a direction crossing a line depicted by the orthogonal surface.

3 . The electrolytic liquid generating device according to claim 1 , wherein:
the mutually adjacent electrodes are formed by a negative electrode and a positive electrode, the laminated body is disposed such that the passage is formed at a negative electrode side, the groove part includes a negative electrode side hole formed in the negative electrode and penetrating in the laminated direction, and the negative electrode side hole is disposed such that a part of the negative electrode side hole in its longitudinal direction is extended in a direction crossing the liquid flowing direction.

4 . The electrolytic liquid generating device according to claim 3 , wherein the negative electrode side hole is disposed such that a first region in which a flowing speed of the liquid in the passage is high is located at a downstream side of a second region in which the flowing speed of the liquid is low compared to the flowing speed of the liquid in the first region.

5 . The electrolytic liquid generating device according to claim 3 , wherein the crossing surface is formed in the negative electrode side hole, and the crossing surface is disposed such that an upward direction of the crossing surface is defined by a direction from a conductive film side toward an opposite side opposite to the conductive film side in a state in which the laminated body is disposed such that the opening side of the groove part is to be an upper side.

6 . The electrolytic liquid generating device according to claim 3 , wherein the conductive film includes a conductive film side hole penetrating in the laminated direction and communicated with the negative electrode side hole.

7 . A liquid modifying device comprising the electrolytic liquid generating device according to claim 1 .

8 . An electric apparatus using electrolytic liquid generated by means of the electrolytic liquid generating device according to claim 1 .
