It is the same dimension as the width of the groove 64 (the dimension in the direction of the short side, the front-rear direction in the main body case 1). When viewed from above, the second groove 64 and the third groove 65 are arranged on a straight line, and the first groove 63, the second groove 64 and the third groove 65 are T-shaped.

With the above configuration, when the water containing active oxygen species in the electrolytic cell 34 is dripped onto the dripping water receiver 60, it accumulates in the dripping water receiver 60, and the water level of the dripping water receiver 60 rises to the level of the sterilization compartment 26. higher than the water level inside. The amount of water containing active oxygen species that is dripped into the dripping water receiver 60 at one time is greater than the amount of water that has accumulated in the dripping water receiver 60 before dripping, and the amount of water that is dripped after dripping is The height of the water level of the water receiving portion 60 is about two to three times the height of the water level of the dripping water receiving portion 60 before dripping. After that, until the water level in the dripping water receiving part 60 reaches the same height as the water level in the sterilization compartment 26, the water containing the active oxygen species in the dripping water receiving part 60 passes through the opening 61, first 1 groove 63. Thus, the water level height of the dripping water receiving part 60 after dripping is about two to three times the water level height of the dripping water receiving part 60 before dripping. The speed at which water containing seeds flows through the openings 61 to the first grooves 63 increases. Furthermore, the water containing active oxygen species flowing through the first groove 63 hits the first groove side wall 63a on the downstream side of the first groove 63 at the tip of the first groove 63 and is divided into two flowing directions. Part of the water containing active oxygen species hits the first groove side wall 63 a on the downstream side of the first groove 63 , changes its direction of flow to the left in the main body case, and flows through the second groove 64 . On the other hand, the rest of the water containing active oxygen species hits the first groove side wall 63a on the downstream side of the first groove 63, changes its direction of flow to the right side of the main body case 1, and flows through the third groove 65. As shown in FIG. As a result, water containing hypochlorous acid, which is dripped and accumulated in the dripping water receiving part 60 and flows into the sterilization section 26 through the opening 61, can be spread widely in the sterilization section 26.例文帳に追加

In addition, the sterilization section 26 has a partition wall 24 that extends upward from the bottom surface of the sterilization section 26 and partitions the sterilization section 26 and the dripping water receiver. there is Specifically, a vertically extending plate-shaped partition wall 24 is provided between the sterilization section 26 and the dripping water receiver 60 . The partition wall 24 is arranged on the front side of the body case of the sterilization section 26, and has an opening 61, which is a rectangular notch, at the lower end of the partition wall 24. As shown in FIG. A part (lower portion) of the opening edge of the opening 61 is the bottom surface of the sterilization section 26, and its width is narrower than the width of the first groove 63 (dimension A in the short side direction, the horizontal direction in the main body case 1). . The sterilization section 26 and the dripping water receiver 60 communicate with each other through the opening 61, and the bottom surface of the sterilization section 26 and the bottom surface of the dripping water receiver 60 are flush with each other.

As a result, part of the water containing hypochlorous acid that has dripped and collected in the dripping water receiving portion 60 flows along the bottom surface of the dripping water receiving portion 60 and flows to the sterilization section 26 through the opening 61. . Here, since the bottom surface of the sterilization section 26 and the bottom surface of the dripping water receiving portion 60 are the same surface, the water containing hypochlorous acid that has dripped and accumulated in the dripping water receiving portion 60 is removed while having momentum. It flows along the bottom surface of the bacteria compartment 26 into the bacteria elimination compartment 26 .

Further, the gas-liquid contact means 23 has a filter 32 partially immersed in water containing hypochlorous acid in the sterilization section 26 and rotated. Specifically, the rotating shaft 32a of the filter 32 is arranged in the horizontal direction at right angles to the direction in which the first groove 63 extends, and the filter 32 rotates downward from the downstream side of the first groove 63 so that the filter A portion of 32 enters the water and rotates upward from the upstream side in the first groove 63 and out of the water. That is, the rotating shaft 32a of the cylindrical filter 32 extends in the left-right direction (perpendicular to the first groove 63 and in the horizontal direction) in the main body case 1, and extends in the second and third grooves 64 and 65, which are elongated squares. are arranged in parallel with the long side direction of (perpendicular to the first groove 63 and horizontal direction). The filter 32 rotates in the direction of the short sides of the second groove 64 and the third groove 65 (the direction in which the first groove 63 extends), which are elongated squares. The filter 32 rotates downward from the rear side of the main body case 1 (the downstream side of the first groove 63) of the second groove 64 and the third groove 65, and a part of the filter 32 enters the water. It rotates upward from the front side of the main body case 1 of the third groove 65 (the upstream side of the first groove 63) and comes out of the water.

As a result, the water containing active oxygen species in the sterilization section 26 accumulated on the back side of the main body case 1 in the second groove 64 and the third groove 65 (the downstream side in the first groove 63) is It becomes easier to flow to the front side of the main body case 1 in the third groove 65 (upstream side in the first groove 63).

When the water containing active oxygen species in the electrolytic cell 34 is dripped and accumulated in the dripping water receiver 60 , it passes through the opening 61 and first flows into the first groove 63 . The water containing reactive oxygen species flowing through the first groove 63 hits the first groove side wall 63a of the first groove 63 at the tip of the first groove 63 and is divided into two flowing directions. 64 hits the first groove side wall 63a on the downstream side of the first groove 63, changes the direction of flow to the left side of the main body case 1, and flows along the second groove side wall 64a on the back side of the main body case 1 of the second groove 64. . On the other hand, the rest of the water containing active oxygen species hits the first groove side wall 63a on the downstream side of the first groove 63 and changes its flow direction to the right side of the main body case 1, and flows into the third groove 65 on the back side of the main body case 1. It flows along the groove side wall 65a. As a result, water containing active oxygen species tends to accumulate on the back side of the main body case 1 in the second groove 64 and the third groove 65 (downstream side in the first groove).

As a result, as the filter 32 rotates, the water containing active oxygen species in the electrolytic cell 34 accumulated in the second groove 64 and the third groove 65 on the back side of the main body case 1 (downstream side in the first groove) is removed. , the water containing active oxygen species in the second groove 64 and the third groove 65 is stirred because it flows to the front side of the main body case 1 in the second groove 64 and the third groove 65 (upstream side in the first groove). can be done.

In addition, the sterilization section 26 has a recessed portion 66 connected to the second groove 64 and recessed downward. The bottom surface of the recessed portion 66 is at the same height as the bottom surface of the second groove 64 .
A first float portion 28 a that moves according to the water level in the recess 66 is provided on the bottom surface of the recess 66 . The recessed portion 66 is arranged on the back side of the main body case 1 (on the downstream side of the first groove 63 ) from the second groove 64 . As a result, water containing active oxygen species can easily accumulate in the recessed portion 66 from the second groove 64 .

As a result, the rotation of the filter 32 causes the water containing reactive oxygen species in the sterilization section 26 accumulated in the recess 66 to move to the rear side of the main body case 1 in the second groove 64 (downstream side in the first groove 63). ) to the front side of the main body case 1 in the second groove 64 (upstream side in the first groove 63), the water containing the active oxygen species in the recess 66 can be agitated.

The second groove 64 is longer than the third groove 65 , and one side of the second groove 64 in the sterilization section 26 is recessed below the third groove 65 . Specifically, the second groove 64 is recessed downward from the third groove 65 and has a step on the front end side extending in a direction perpendicular to the first groove 63 from the front end of the first groove 63 . As a result, when the water that has flowed from the opening 61 along the first groove 63 flows through the second groove 64, which is longer than the third groove 65 and does not easily flow to the tip, the downwardly recessed step increases the force of the water. It is easy to flow up to the tip direction of the two grooves 64 .
