Description

  Aspects of the present invention generally relate to an acidic water generator and a toilet device.

Patent Document 1 discloses a technique for electrolyzing tap water in an electrolytic cell and spraying sterilized water containing hypochlorous acid generated thereby on a toilet to suppress the growth of bacteria.
When producing such sterilizing water, a scale mainly composed of sodium, calcium, potassium, magnesium or the like adheres to the cathode side of the electrode in the electrolytic cell. When the amount of the scale adhering to the electrode is increased, the electrolysis performance may be lowered, and the sterilizing water generating ability may be lowered.

  Therefore, the acidic water generator disclosed in Patent Document 2 performs pole change that alternately reverses the polarity of the voltage applied between the electrodes, and removes the scale attached to the cathode side. Further, the acidic water generating device has a flow path switching means for switching the flow path of the functional water discharged from the electrolytic cell, and a downstream port of the flow path switching means leads to a port leading to a toilet and a drain pipe. Port is connected. When the pole change is performed, the acidic water and the alkaline water are also controlled during the pole change by controlling the flow path switching means so that the acidic water is led to the toilet and the alkaline water is led to the drain pipe. It is configured so that the discharge destination does not change.

Inside the electrolytic cell 51, a first electrode 511 and a second electrode 512 are provided to face each other. The control unit 41 controls the voltage applied between the pair of electrodes, and electrolyzes tap water flowing inside the electrolytic cell 51. Here, the tap water contains chloride ions such as sodium chloride (NaCl) and calcium chloride (CaCl ₂ ). For this reason, by electrolyzing tap water, chlorine is generated from chloride ions on the anode side of the first electrode 511 and the second electrode 512. Then, the generated chlorine is dissolved in water, and acidic water containing hypochlorous acid is generated. At this time, in the cathode-side electrode, alkaline water is generated, and scale is generated from ions such as calcium contained in tap water, and adheres to the surface of the electrode.

  In order to suppress the deposition of the scale generated at the cathode side electrode, pole change is performed in which the polarity of the voltage applied to the first electrode 511 and the second electrode 512 is periodically reversed. Accordingly, the polarity of the electrolyzed water generated in the vicinity of the first electrode 511 and the polarity of the electrolyzed water generated in the vicinity of the second electrode 512 are periodically reversed.

  The electrolytic cell 51 is connected to a first discharge channel 51a and a second discharge channel 51b from which acidic water and alkaline water are discharged, respectively. The first discharge channel 51a is connected to the first electrode 511 side, and the electrolyzed water generated on the first electrode 511 side is discharged.

Or it is made to communicate with the alkaline water flow path 52b. Specifically, the flow path switching means 52 guides acidic water flowing through one of the first discharge flow path 51a and the second discharge flow path 51b to the acidic water flow path 52a, and the first discharge flow path 51a and the second discharge flow path. The alkaline water flowing through the other side of the channel 51b is guided to the alkaline water channel 52b.

The acidic water flow path 52 a is connected to the aluminum tank 53. Aluminum is provided in the aluminum tank 53, and this aluminum is immersed in the acidic water guided to the aluminum tank 53. Aluminum immersed in acidic water dissolves (slow dissolution) over a predetermined time. Thereby, the acidic water in the aluminum tank 53 becomes acidic water (aluminum ion acidic water) containing aluminum ions (Al ³⁺ ).

  The aluminum ion acidic water produced | generated by the aluminum tank 53 is guide | induced to the spray nozzle 46 (ejection part) as represented to FIG. The spray nozzle 46 is provided in the casing 40, for example. The spray nozzle 46 may be provided inside the casing 40 or may be attached outside the casing 40. The spray nozzle 46 sprays (sprays) the aluminum ion acidic water supplied from the aluminum tank 53 toward the surface of the bowl 81 in the form of a mist.

  The alkaline water flow path 52b is connected to a discharge destination different from the spray nozzle 46, such as a drain pipe or a jet hole of the toilet 80.

  The amount of scale deposited in the flow path through which the alkaline water flows increases as the pH of the alkaline water increases. When alkaline water is diluted with non-electrolyzed water, the pH of the alkaline water decreases. Therefore, the accumulation of scale in the first discharge channel 51a, the second discharge channel 51b, and the alkaline water channel 52b through which alkaline water flows is suppressed, and the channel is not easily clogged by the scale.

  Moreover, according to this embodiment, since alkaline water is diluted with the 1st discharge flow path 51a or the 2nd discharge flow path 51b comparatively close to the electrolytic cell 51, the deposition of the scale in the flow path through which alkaline water flows is effective.
