The root of 2 ribs 36 of last shell 21 be formed with respectively in the rib 36 that rectangular substantially through hole 39. is formed at outlet 33 sides through hole 39 also according to greater than form with the rib 36 that exports 33 opposite sides in the mode of through hole 39 form. still, through hole is not limited to rectangular substantially type, also can be such as, circular hole.

Like this, by through hole 39 is set in rib 36, be that thus near the brine electrolysis that (electrode 34) produces in the tank house 27 passes through the top of electrode 34 when outlet is flowed, brine electrolysis flows towards outlet 33 by through hole 39, the situation of the mobile variation of brine electrolysis so prevent to keep the rib 36 of electrode 34 usefulness to counteract.

In addition, the hydrogen that electrolysis when generating because of brine electrolysis produces also can be sent to outlet 33 sides well by the through hole 39 that is formed in the rib 36, discharge from the inside of tank house 27. thus, water in the tank house 27 is flowed well, and prevent situation about reducing in the efficient of the inside of tank house 27 electrolysis because of with hydrogen storage, like this, adopt brine electrolysis to clean washings more well.

As shown in Figure 3, horizontal direction is formed with inclined plane 211A relatively in the bottom surface (inner face) of the top plate portion 211 of last shell 21, this inclined plane 211A is according to following the mode that 25 side height increase gradually towards the peripheral passage to tilt. on the other hand, the end face (inner face) of the base plate 221 of lower casing 22 relatively horizontal direction be formed with inclined plane 221A, this inclined plane 221A is according to following the mode that reduces gradually towards peripheral passage 25 side height to tilt. the angle of inclination of the relative horizontal direction among the inclined plane 221A of lower casing 22 is set according to the mode less than the angle of inclination of the relative horizontal direction among the inclined plane 211A of last shell 21.

If adopt such scheme, then can be when draining the water in the brine electrolysis 27 be sent to peripheral passage 25 sides well along the inclined plane 221A of lower casing 22, well this water is discharged by peripheral passage 25. therefore, can prevent from after draining finishes, to be in water be stored in tank house 27 inside state and be arranged at the disadvantage that electrode 34 tank house 27 in takes place to corrode etc.

In addition, in the present embodiment, the sectional area of the horizontal direction of peripheral passage 25 (with the perpendicular direction of the circulating direction of water) according to setting (with reference to Fig. 3) greater than the mode of the aperture area that is formed at inlet 32 in the partition wall 26 and outlet 33 if. such formation, then when generating, brine electrolysis can make according to the water of lower speed inner loop of 25 from 32 inside that flow into tank house 27 well that enter the mouth in the peripheral passage, generate brine electrolysis, on the other hand, when discharging, can make with the higher speed shipwreck that 25 inside flow to draining valve 14 sides in the peripheral passage in from entering the mouth 32 or export 33 inside that enter into tank house 27.

Therefore, owing to can make the broken cotton yarn that when draining, in the water of peripheral passage 25 internal flows, comprises etc. be difficult to enter tank house 27, so prevent the situation that the electrolytic efficiency of tank house 27 inside reduces because broken cotton yarn is stored in the inside of tank house 27 more effectively, can adopt brine electrolysis more well washings to be cleaned.

Also have, in the present embodiment, the aperture area of the outlet 33 above being arranged in inlet 32 on being formed at partition wall 26 and the outlet 33 according to setting (with reference to Fig. 3) greater than the mode of the aperture area of the inlet below being arranged at 32 if. adopt such scheme, the hydrogen that then can the electrolysis when generating because of brine electrolysis produces is discharged from tank house 27 inside well by the bigger outlet 33 of aperture area that is arranged at the top. thus, water in the tank house 27 is flowed well, and can prevent since hydrogen storage in the inside of tank house 27 and the situation that the efficient of electrolysis reduces, like this, can adopt brine electrolysis more well washings to be cleaned.
