Mode for Carrying Out the Invention

[0009] (Embodiment 1) The first embodiment of the present disclosure will be described with reference to the drawings.

[0010] FIG. 1 and FIG. 2 are perspective views of the air purifier 1 equipped with the electrolyzed water generator of the first embodiment of the present disclosure. Note that FIG. 1 is a view of the air purifier equipped with the electrolyzed water generator as seen obliquely from above on the front side. FIG. 2 is a view of the air purifier 1 with the panel opened as seen obliquely from above on the front side. Further, FIG. 3 is a view showing a cross-sectional configuration of the air purifier 1 equipped with the electrolyzed water generator as seen from the right side facing the front.

[0011] In the following, as shown in FIG. 1, in the state where the air conditioner is installed (hereinafter also referred to as the "installed state"), the vertical direction may be described as the up-and-down direction, and the horizontal direction may be described as the left-and-right direction. Further, in the installed state, the surface of the air conditioner on which the panel 9 is provided is referred to as the "right side surface", and the surface facing the right side surface of the air conditioner is referred to as the "left side surface". The left side as seen from the right side surface of the air conditioner is the "front", and the right side as seen from the right side surface of the air conditioner is the "back".

[0012] The electrolyzed water generator 22 may be mounted on the air purifier 1. As shown in FIGS. 1 to 3, the air purifier 1 equipped with the electrolyzed water generator of the present embodiment includes a substantially box-shaped main body case 2, a blower 3, an air purification unit 4, a control unit 5, and an operation unit 6, and the electrolyzed water generator is included in the air purification unit 4. Hereinafter, the air purifier 1 and the electrolyzed water generator mounted on the air purifier 1 will be described.

[0013] The main body case 2 has a vertically long substantially box shape, and an intake port 7, an air outlet 8, and a panel 9 are provided on the main body case 2.

[0014] The air intake ports 7 are located on the left and right sides of the main case 2.

[0015] The air outlet 8 is located on the rear side of the top surface of the main body case 2. The control panel 6 is located on the front side of the top surface of the main body case 2.

[0016] A retractable panel 9 is provided on the right side (one side) of the main case 2. When panel 9 is opened, an air purification unit 4 is located inside the main case 2.

[0017] As shown in Figure 3, the main body case 2 is provided with an air passage 11 (indicated by an arrow) that connects the air intake 7 and the air outlet 8. The air passage 11 is provided with, in order from the air intake 7, an air purification unit 4 (including a water storage container 19 and a filter, which will be described later), a blower 3, and an air outlet 8.

[0018] The blower 3 is located at the top of the main body case 2 and comprises a motor unit 12, a fan unit 13 that rotates with respect to the motor unit 12, and a scroll-shaped casing unit 14 that surrounds them.

[0019] The motor unit 12 is a single-shaft motor, and the rotating shaft 15 of the motor unit 12 extends from the front side to the rear side of the main body case 2.

[0020] The fan unit 13 is a sirocco fan and is fixed to the tip of a rotating shaft 15 that extends horizontally from the motor unit 12.

[0021] The casing section 14 is provided with a discharge port 16 and a suction port 17. The discharge port 16 is located on the upper side of the main body case 2 of the casing section 14. The suction port 17 is located on the rear side of the main body case 2 of the casing section 14. When the fan section 13 is rotated by the motor section 12, air from outside the casing section 14 flows into the casing section 14 through the suction port 17, and air is blown out of the casing section 14 through the discharge port 16.

[0022] Figure 4 is a perspective view of an air purification device 1 equipped with an electrolytic water generator according to the first embodiment of the present disclosure, showing the air purification device 1 viewed from the front and slightly above with the panel 9 open and the tank member 20 removed. Figure 5 is a perspective view of an air purification device equipped with an electrolytic water generator according to the first embodiment of the present disclosure, showing the air purification device 1 viewed from the front and slightly above with the panel 9 open and the water storage container 19 removed.

[0023] As shown in Figures 4 and 5, the air purification unit 4 is located within the cavity 10. The cavity 10 is a recessed hole extending from one side (right side) of the main body case 2 to the other side (left side) of the main body case 2. The air purification unit 4 can be removed from the cavity 10 to the outside of the main body case 2. The air purification unit 4 comprises a water storage container 19, a tank member 20, a gas-liquid contact portion 21, and an electrolytic water generator 22.

[0024] The water storage container 19 is made of resin, has a roughly box-like shape with an opening on its top surface, and is equipped with a structure that allows it to store water. The water storage container 19 is located at the bottom of the main body case 2 and is positioned to be removable by sliding horizontally from the cavity 10. The water storage container 19 stores water supplied from the tank member 20.

[0025] Figure 6 is an exploded perspective view of the tank member 20 of the first embodiment of the present disclosure. Figure 7 is Figure 8 shows the cross-sectional configuration of the tank member 20 in the first embodiment of the disclosure. Figure 9 shows the cross-sectional configuration of the water storage container 19 in the first embodiment of the disclosure.

[0026] As shown in Figures 6 to 9, the tank component 20 is installed in the lower part inside the main body case 2 and has a structure that allows it to be attached to and detached from the water storage container 19. The bottom surface of the water storage container 19 is provided with a tank holding portion 23 that protrudes upward.

[0027] The tank member 20 is mounted on the bottom surface of the water storage container 19 at the position of the tank holding portion 23. The tank member 20 has a tank 24 for storing water, an opening 24a provided on the bottom surface of the tank 24 that connects the inside of the tank 24 to the outside of the tank 24, and a lid 25 that covers the opening 24a.

[0028] The lid 25 has a hole 25b in the center that communicates vertically, a valve 26 that opens and closes the hole 25b, and a cylindrical portion 25a that surrounds the hole 25b, with its central axis extending vertically and protruding downward from the lid 25. The hole 25b is located in the center when viewed in the direction of the central axis of the cylindrical portion 25a.

[0029] In the above configuration, when the opening 24a of the tank 24 is facing downwards and the tank member 20 is attached to the tank holding part 23 of the water storage container 19, the valve part 26 is opened by the tank holding part 23. In other words, when water is placed in the tank member 20 and attached to the tank holding part 23, the valve part 26 moves upwards by the tank holding part 23, and the hole 25b of the lid 25 opens. When the hole 25b of the lid 25 opens, the water in the tank 24 is supplied to the water storage container 19 through the hole 25b of the lid 25, and water accumulates in the water storage container 19.

[0030] When the water level in the water storage container 19 rises and reaches the upper end of the notch 25c at the lower end of the cylindrical portion 25a of the lid 25, the hole 25b of the tank member 20 is sealed with water, and the water supply stops. Water remains inside the tank member 20, and whenever the water level in the water storage container 19 drops, water from inside the tank is supplied to the water storage container 19. In other words, the water level in the water storage container 19 is kept constant.

[0031] Figure 10 is a perspective view of a water storage container 19 of the first embodiment of this disclosure with a gas-liquid contact portion 21 attached.

[0032] As shown in Figures 8 and 10, the gas-liquid contact portion 21 is a component that brings the water stored in the water storage container 19 into contact with the indoor air drawn into the main body case 2 by the blower 3. The gas-liquid contact portion 21 includes a filter 27, a filter frame 28, and a drive unit (not shown).

[0033] The filter 27 is cylindrical in shape and has holes in its circumference that allow air to flow through. The filter 27 is mounted on the filter frame 28 such that one end of the filter 27 is immersed in the water in the water storage container 19.

[0034] The filter frame 28 is rotatably supported by a bearing portion 30 provided in the water storage container 19. The filter 27 and the filter frame 28 have a structure that allows them to rotate by a drive unit.

[0035] As shown in Figures 4 and 5, the electrolytic water generator 22 is detachably attached to the main body case 2 and is mounted to be movable in the vertical direction. In Figure 4, the electrolytic water generator 22 is in a downward position. The electrolytic water generator 22 has a first electrode plate 51 and a second electrode plate 52 (see Figure 14, which will be described later).

[0036] When the water storage container 19 is attached to the cavity 10 at the bottom of the main case 2 and the electrolytic water generator 22 is moved downward, the first electrode plate 51 and the second electrode plate 52 are immersed in the water storage container 19. With the first electrode plate 51 and the second electrode plate 52 immersed in the water storage container 19, when a voltage is applied to the first electrode plate 51 and the second electrode plate 52, the water in the water storage container 19 containing the electrolysis promoting solvent is electrochemically treated.

[0037] One example of an electrolytic accelerating solvent is sodium chloride, and hypochlorous acid is generated from an aqueous sodium chloride solution by the electrolytic water generator 22. The electrolytic water generator 22 is also detachable from the main body case 2.

[0038] As shown in Figures 4, 8 to 10, the water storage container 19 has an electrolytic cell 31 for storing water containing sodium chloride, and a sterilization tank 32 to which water containing reactive oxygen species from the electrolytic cell 31 is supplied. The water storage container 19 is divided into the electrolytic cell 31 and the sterilization tank 32 by a partition plate 19a.

[0039] The electrolytic cell 31 is equipped with a tank member 20 and an electrolytic water generator 22. The tank member 20 is detachably attached to the electrolytic cell 31 and supplies water to the electrolytic cell 31. An electrolytic accelerating solvent is introduced into the electrolytic cell 31 by an automatic salt dispensing unit 33, and the electrolytic cell 31 stores water containing sodium chloride, which is the electrolytic accelerating solvent. An opening (not shown) is provided at the bottom of the partition plate 19a that connects the electrolytic cell 31 and the sterilization tank 32. The water containing sodium chloride, which is the electrolytic accelerating solvent in the electrolytic cell 31, flows into the sterilization tank 32 through the opening in the partition plate 19a.

[0040] In the sterilization tank 32, the gas-liquid contact area 21 is positioned such that the lower end of the filter 27 is immersed in water containing reactive oxygen species. The blower 3 draws air in from the intake port 7 and blows it through the gas-liquid contact area 21 to the outlet port 8.

[0041] The electrolytic water generator 22 is configured to move vertically, and by moving it downward, the first electrode plate 51 and the second electrode plate 52 of the electrolytic water generator 22 are immersed in the water in the electrolytic cell 31 (see Figure 14, described later). In this state, the electrolytic water generator 22 electrolyzes the water containing sodium chloride in the electrolytic cell 31, which is the water to be treated, to produce water containing reactive oxygen species, or electrolytic water. Near the second electrode plate 52 on the cathode side, hydrogen ions (H+) are decomposed into hydrogen gas, relatively increasing the concentration of hydroxide ions (OH-) and generating alkaline ionized water as electrolytic water. Near the first electrode plate 51 on the anode side, hydroxide ions (OH-) are decomposed, relatively increasing the concentration of hydrogen ions (H+) and generating strongly acidic water as electrolytic water. At the same time, chloride ions (Cl-) in the water in the electrolytic cell 31 are converted into chlorine gas, which then reacts with water to generate reactive oxygen species as electrolytic water, which are antibacterial components. When the electrolytic water generator 22 is moved upward, the electrolytic water generator 22 is positioned above the water storage container 19.

[0042] Here, reactive oxygen species refer to oxygen molecules with higher oxidative activity than ordinary oxygen, and related substances. For example, reactive oxygen species include not only so-called reactive oxygen species in the narrow sense, such as superoxide anions, singlet oxygen, hydroxyl radicals, or hydrogen peroxide, but also so-called reactive oxygen species in the broad sense, such as ozone and hypochlorous acid (hypohalous acid). In this embodiment, the production of electrolyzed water containing reactive oxygen species (in this case, hypochlorous acid) may be expressed as generating reactive oxygen species (in this case, hypochlorous acid).

[0043] Figure 11 is a perspective view of the automatic salt dispensing unit 33 of the air purification device 1. Figure 12 is a cross-sectional perspective view of the automatic salt dispensing unit 33 of the air purification device 1. As shown in Figures 2, 11, and 12, the automatic salt dispensing unit 33 is installed above the water storage container 19 and includes a tablet dispensing case 34, a tablet dispensing member 35 provided inside the tablet dispensing case 34, and a detachable member provided on the upper part of the tablet dispensing case 34. The device is equipped with a tablet insertion cover 36. When the tablet insertion cover 36 is removed from the tablet insertion case 34 and the electrolytic accelerating solvent 37 is placed inside the tablet insertion case 34, the tablet insertion member 35 rotates, and the electrolytic accelerating solvent 37 automatically falls into the water storage container 19 through the opening 38 at the bottom of the tablet insertion case 34.

[0044] The control unit 5 controls the electrolytic water generator 22, the drive unit for the gas-liquid contact section 21, the motor unit 12 of the blower 3, and the automatic salt dispenser 33. Specifically, the control unit 5 controls the voltage applied to the first electrode plate 51 and the second electrode plate 52 of the electrolytic water generator 22, the operation of the drive unit for the gas-liquid contact section 21, the rotation speed of the fan unit 13 of the blower 3, the operation of the tablet dispenser 35 of the automatic salt dispenser 33, etc., in response to the operation of the operation unit 6.

[0045] As shown in Figure 3, when the fan unit 13 rotates due to the motor unit 12 of the blower 3, air is blown into the air passage 11. When the fan unit 13 rotates, outside air that enters the main body case 2 from the intake port 7 is sequentially blown out of the main body case 2 via the filter 27 of the air purification unit 4, the blower 3, and the outlet port 8.

[0046] Figure 13 is a perspective view of the electrolytic water generator. Figure 14 is an exploded perspective view of the electrolytic water generator, showing the inside of the second electrode case 59. Figure 15 is an exploded perspective view of the electrolytic water generator, showing the inside of the first electrode case 58. Figure 16 is a diagram showing the inside of the electrolytic water generator. Figure 17 is a perspective view showing the inside of the electrolytic water generator.

[0047] As shown in Figures 13, 14, 15, 16, and 17, the electrolytic water generator 22 includes an electrode case 50, a first electrode plate 51, a second electrode plate 52, a first connecting plate 53, a first electric wire 54, a second connecting plate 55, a second electric wire 56, and a spacer 57.

[0048] The electrode case 50 is made of an insulating resin and is roughly box-shaped. The electrode case 50 has a first electrode case 58 and a second electrode case 59. The first electrode case 58 and the second electrode case 59 are roughly shallow dish-shaped, and the periphery of the first electrode case 58 and the periphery of the second electrode case 59 overlap to form a roughly thin box-shaped electrode case 50. The bottom surface of the electrode case 50 has a plurality of openings 50a. Water in the water storage container 19 enters the electrode case 50 through the openings 50a.

[0049] The first electrode plate 51 is a horizontally elongated plate, with one long side extending horizontally being the upper end and the other long side extending horizontally being the lower end. Both short sides extend vertically. The substrate of the first electrode plate 51 is made of titanium, and the coating layer is a platinum layer such as platinum plating. A platinum-plated conductive metal coating layer is formed on both sides of the first electrode plate 51. The first electrode plate 51 has a circular opening, the first electrode hole 60, in the center in the left-right direction near the upper end.

[0050] The second electrode plate 52 is a horizontally elongated plate, with one long side extending horizontally being the upper end and the other long side extending horizontally being the lower end. Both short sides extend vertically. The substrate of the second electrode plate 52 is made of titanium, and the coating layer is a platinum layer such as platinum plating. A platinum-plated conductive metal coating layer is formed on both sides of the second electrode plate 52. The second electrode plate 52 has a circular opening, the second electrode hole 61, in the center in the left-right direction near the upper end. The first electrode plate 51 and the second electrode plate 52 are provided in the electrode case 50 such that their vertically extending surfaces face each other.

[0051] The first connecting plate 53 is a roughly elongated plate-shaped conductive metal that extends upward from the surface of the first electrode plate 51 facing the second electrode plate 52. A portion of the lower part of the first connecting plate 53 (the other side in the longitudinal direction of the first connecting plate 53) on the first electrode plate 51 side contacts the inner surface of the first electrode plate 51 (the side facing the second electrode plate 52), and the first connecting plate 53 and the first electrode plate 51 are electrically connected. The lower part of the first connecting plate 53, which is on the side of the first electrode plate 51 (the other side in the longitudinal direction of the first connecting plate), has a circular opening called the first connecting hole 62.

[0052] The first electric wire 54 extends from the upper part of the first connecting plate 53 opposite to the first electrode plate 51 (one side in the longitudinal direction of the first connecting plate 53). The first electric wire 54 is fixed to the first connecting plate 53 by the first fixing part 54a. The first electric wire 54 is connected to an electric wire (not shown) extending from the control unit 5. The first electric wire 54 electrically connects the first connecting plate 53 and the electric wire extending from the control unit 5.

[0053] The second connecting plate 55 is a substantially elongated plate-shaped conductive metal that extends upward from the surface of the second electrode plate 52 facing the first electrode plate 51. A portion of the lower part of the second connecting plate 55 on the second electrode plate 52 side (the other side in the longitudinal direction of the second connecting plate 55) contacts the inner surface of the second electrode plate 52 (the side facing the first electrode plate 51), and the second connecting plate 55 and the second electrode plate 52 are electrically connected. The lower part of the second connecting plate 55 on the second electrode plate 52 side (the other side in the longitudinal direction of the second connecting plate 55) has a circular opening called the second connecting hole 63.

[0054] The second wire 56 extends from the upper part of the second connecting plate 55, opposite to the second electrode plate 52 (one side in the longitudinal direction of the second connecting plate 55). The second wire 56 is fixed to the second connecting plate 55 by the second fixing part 56a. The second wire 56 is connected to the wire extending from the control unit 5. The second wire 56 electrically connects the second connecting plate 55 and the wire extending from the control unit 5.

[0055] The spacer 57 is made of an insulating material and is sandwiched between the first connecting plate 53 and the second connecting plate 55. The spacer 57 has a circular opening in the center, which is a spacer hole 64.

[0056] The first electrode plate 51, the first connecting plate 53, the second electrode plate 52, the second connecting plate 55, and the spacer 57 are arranged laterally in the order of first electrode plate 51, first connecting plate 53, spacer 57, second connecting plate 55, and second electrode plate 52, and the centers of the first electrode hole 60, first connecting hole 62, spacer hole 64, second connecting hole 63, and second electrode hole 61 are aligned on the same line. Bolts 65 made of insulating material are inserted sequentially through the first electrode hole 60, first connecting hole 62, spacer hole 64, second connecting hole 63, and second electrode hole 61, and are fixed with nuts 66 made of insulating material. The first electrode plate 51, the first connecting plate 53, the spacer 57, the second connecting plate 55, and the second electrode plate 52, which are fixed by bolts 65 and nuts 66, are mounted inside an electrode case 50 consisting of a first electrode case 58 and a second electrode case 59.

[0057] Between the first electrode plate 51 and the second electrode plate 52, a first connecting plate 53, a spacer 57, and a second connecting plate 55 are sandwiched and fixed with bolts 65 and nuts 66. This allows the distance between the first electrode plate 51 and the second electrode plate 52 to be maintained at a precise and uniform distance, thereby stabilizing electrolysis.

[0058] Furthermore, the first electrode hole 60 is provided above the first electrode plate 51, and the second electrode hole 61 is provided above the second electrode plate 52. The distance between the upper end of the first electrode plate 51 and the first electrode hole 60 is shorter than the radius of the first electrode hole 60, and the distance between the upper end of the second electrode plate 52 and the second electrode hole 61 is shorter than the radius of the second electrode hole 61. The distance between the lower end of the first connecting plate 53 and the first connecting hole 62 is shorter than the radius of the first connecting hole 62, and the distance between the lower end of the second connecting plate 55 and the second connecting hole 63 is shorter than the radius of the second connecting hole 63.

[0059] With the above configuration, the area of ​​the first electrode plate 51 covered by the first connecting plate 53 and the area of ​​the second electrode plate 52 covered by the second connecting plate 55 are reduced. The first connecting plate 53 and the second connecting plate 55 reduce the area of ​​the first electrode plate 51 and the second electrode plate 52 that can be used for electrolysis. It can be reduced.

[0060] Furthermore, the electrode case 50 comprises a first electrode case 58 and a second electrode case 59, with the peripheral edges of the first electrode case 58 and the peripheral edges of the second electrode case 59 overlapping to form a substantially thin, box-shaped electrode case 50. The first electrode case 58 includes an electrode rotation prevention rib 72 that suppresses the rotation of the first electrode plate and the second electrode plate, and a bolt rotation prevention rib 73 that suppresses the rotation of the bolt.

[0061] The electrode rotation prevention rib 72 is a projection that extends from the first electrode case 58 toward the second electrode case 59.

[0062] The bolt rotation prevention rib 73 is a projection that extends from the first electrode case 58 toward the second electrode case 59. When viewed from the second electrode case 59 side, the bolt rotation prevention rib has a hexagonal cylindrical shape. The head of the bolt 65 has a hexagonal prism shape, and the head of the bolt 65 is fitted into the hexagonal cylindrical bolt rotation prevention rib. When the head of the bolt 65 is placed inside the bolt rotation prevention rib and the inside of the first electrode case 58 is viewed from the second electrode case 59 side, a small gap is created between the peripheral edge of the bolt 65 head and the inner surface of the bolt rotation prevention rib. However, when the bolt 65 is rotated in the direction that the nut 66 rotates with the head of the bolt 65 inside the bolt rotation prevention rib, the head of the bolt 65 hits the bolt rotation prevention rib and is unable to rotate. Assembly becomes easier if the head of the bolt 65 is placed inside the bolt rotation prevention rib, and the first electrode plate 51, first connecting plate 53, spacer 57, second connecting plate 55, and second electrode plate 52 are attached to the bolt 65 in that order, and then secured with a nut 66.

[0063] When the first electrode plate 51 rotates around the center of the first electrode hole 60 as its axis of rotation, the end of the first electrode plate 51 furthest from the center of the first electrode hole 60 contacts the electrode rotation prevention rib 72. When the second electrode plate 52 rotates around the center of the second electrode hole 61 as its axis of rotation, the end of the second electrode plate 52 furthest from the center of the second electrode hole 61 contacts the electrode rotation prevention rib 72. Specifically, the end of the first electrode plate 51 furthest from the center of the first electrode hole 60 is the lower corner of the first electrode plate 51 located between the long side and the short side of the lower end of the first electrode plate 51. The end of the second electrode plate 52 furthest from the center of the second electrode hole 61 is the lower corner of the second electrode plate 52 located between the long side and the short side of the lower end of the second electrode plate.

[0064] In this way, when the head of the bolt 65 is placed inside the bolt rotation prevention rib and the bolt 65 is rotated in the direction in which the nut 66 rotates, the end of the first electrode plate 51 furthest from the center of the first electrode hole 60 contacts the electrode rotation prevention rib 72, and the end of the second electrode plate 52 furthest from the center of the second electrode hole 61 contacts the electrode rotation prevention rib 72, so that the first electrode plate 51 and the second electrode plate 52 can easily face each other without shifting.

[0065] Figure 18 shows a spacer for the electrolytic water generator. The spacer 57 has a first cylindrical portion 57a ​​that protrudes between the bolt 65 and the first electrode hole 60 of the first electrode plate 51, and a second cylindrical portion (not shown) that protrudes between the bolt 65 and the second electrode hole 61 of the second electrode plate 52. The distance between the first cylindrical portion 57a ​​and the first electrode hole 60 is smaller than the distance between the first cylindrical portion 57a ​​and the bolt 65, and the distance between the second cylindrical portion and the second electrode hole 61 is smaller than the distance between the second cylindrical portion and the bolt 65.

[0066] As a result, the distance between the first cylindrical portion 57a ​​and the first electrode hole 60, and the distance between the second cylindrical portion and the second electrode hole 61 become smaller, reducing play and making it easier for the first electrode plate 51 and the second electrode plate 52 to face each other.

[0067] Furthermore, as shown in Figures 14, 15, 16, and 17, the first electrode case 58 is bolt The bolt 65 has a first electrode support portion 74 that supports the first electrode plate 51 from the first electrode case 58 side in the rotation axis direction, and a second electrode support projection 75 that supports the second electrode plate 52 from the first electrode case 58 side in the rotation axis direction of the bolt 65. The second electrode case 59 has a second electrode support portion 76 that supports the second electrode plate 52 from the second electrode case 59 side in the rotation axis direction of the bolt 65, and a first electrode support projection 77 that supports the first electrode plate 51 from the second electrode case 59 side in the rotation axis direction of the bolt 65.

[0068] Specifically, the first electrode support portion 74 has a first opposing surface 74a, which is a surface facing the surface of the first electrode plate 51. The first opposing surface 74a is flat and contacts the surface of the first electrode plate 51 on the first electrode case 58 side.

[0069] The first electrode plate 51 has a semicircular notch, or first notch portion 51a, on its lower end. The second electrode support projection 75 extends from the inner surface of the first electrode case 58 through the first notch portion 51a to the second electrode plate 52. The tip of the second electrode support projection 75 contacts the surface of the second electrode plate 52 that is on the side of the first electrode plate 51, and supports the second electrode plate 52.

[0070] Furthermore, the second electrode support portion 76 has a second opposing surface 76a, which is a surface facing the surface of the second electrode plate 52. The second opposing surface 76a is flat and contacts the surface of the second electrode plate 52 that faces the second electrode case 59.

[0071] The second electrode plate 52 has a semicircular notch, or second notch portion 52a, on its lower end. The first electrode support projection 77 extends from the inner surface of the second electrode case 59 through the second notch portion 52a to the first electrode plate 51. The tip of the first electrode support projection 77 contacts the surface of the first electrode plate 51 that is on the side of the second electrode plate 52, and supports the first electrode plate 51.

[0072] This ensures that the flatness of the first electrode plate 51 and the second electrode plate 52 is maintained, allowing the distance between the first electrode plate 51 and the second electrode plate 52 to be kept precise and uniform, thereby stabilizing electrolysis.

[0073] Furthermore, the second electrode case 59 is a resin molded part, and the first opposing surface 74a of the first electrode support portion 74 is part of the first recessed portion in the first electrode case 58 that is recessed toward the second electrode case 59. As a result, the flatness of the first opposing surface 74a is easily achieved and its strength is increased, thus maintaining the flatness of the first electrode plate 51.

[0074] Furthermore, the first electrode case 58 is a resin molded part, and the second opposing surface 76a of the second electrode support portion 76 is part of the second recessed portion in the second electrode case 59 that is recessed toward the first electrode case 58. As a result, the flatness of the second opposing surface 76a is easily achieved and its strength is increased, thus maintaining the flatness of the second electrode plate 52.
