  The electrolyzed water produced by the electrolyzed water mist generator described in Patent Document 1 contains hypochlorous acid. Hypochlorous acid is a necessary component because it has a bactericidal and deodorizing action, but it is preferable that it does not exist more than necessary considering the influence on the surroundings. Therefore, in the electrolyzed water mist generator, it is necessary to suppress the amount of water supplied to the tray to a small amount in order to minimize the generation of electrolyzed water itself.

Here, not only in the case of an air cleaner, a configuration in which an electrolyzed water mist generator and a humidifier are combined and the mist of electrolyzed water is placed on the air humidified by the humidifier can be considered. The water mist generator needs to keep the amount of water supplied to the tray small, while the humidifier always needs a sufficient amount of water to ensure humidification performance.
In such a case, for example, since both a small-capacity water supply tank for an electrolyzed water mist generator and a large-capacity water tank for a humidifier are required, complication of the configuration becomes unavoidable, and the size of the apparatus is increased. Problems such as high manufacturing costs can occur.

The present invention has been made based on such a background, and can be used in combination with an electrolyzed water unit with a simple configuration, and is a humidifier that can minimize the generation of electrolyzed water in the electrolyzed water unit.

The generation of electrolyzed water at the can be minimized.
In addition, since the electrolyzed water unit generates electrolyzed water using a part of the water for humidification stored in the water storage section, the electrolyzed water unit supplies water only for the electrolyzed water generation in the electrolyzed water unit ( It is not necessary to provide a separate water supply tank or the like, and the electrolyzed water unit and the humidifier can be combined with a simple configuration.

According to invention of Claim 2, since the electrolyzed water unit is arrange | positioned in the inner space enclosed by the inner periphery in the cyclic | annular humidification board, it can receive the water which falls from a humidification board reliably, Furthermore, since it will be arrange | positioned in a flow path like a humidification board, electrolyzed water can be reliably put on the air of a flow path.
Further, since the humidifying plate is provided with a rib for guiding the water traveling on the surface of the humidifying plate to the electrolyzed water unit, the electrolyzed water unit can receive water falling from the humidifying plate more reliably.

According to the third aspect of the present invention, since the inner peripheral edge of the humidifying plate is formed with a plurality of cuts at intervals in the circumferential direction, it reaches the inner peripheral edge of the humidifying plate along the surface of the humidifying plate.

Therefore, if the holding member is rotated, the diffusion plate can also be rotated. Therefore, if there is a mechanism for rotating the holding member, it is not necessary to provide a separate mechanism for rotating the diffusion plate, and the number of parts can be reduced. Can be achieved.

According to the sixth aspect of the present invention, in the diffusion plate, a plurality of small holes formed so as to be radially arranged with respect to the center of rotation forms a film of electrolyzed water for the water receiving container by surface tension. The Thus, electrolyzed water can be efficiently diffused with a simple configuration in which a small hole is provided in the diffusion plate and the electrolyzed water film formed in the small hole is exposed to the air in the flow path.
According to invention of Claim 7, even if it is a motor which cannot adjust speed | velocity, a control means can set the rotational speed of a humidification board arbitrarily by operating a motor intermittently.

Next, assembly of the humidifying unit 20 will be described.
First, as shown in FIG. 5, the front plate 30, the humidifying plate 32, and the rear plate 31 are arranged concentrically in this order from the front side. Here, a plurality of humidifying plates 32 (for example, 17) are arranged in a state where they are overlapped in the front-rear direction (only one humidifying plate 32 is shown in FIG. 5). Since the 1st protrusion 47, the 2nd protrusion 48, and the convex part 49 which were provided in each humidification board 32 are interposed between the adjacent humidification boards 32, in the adjacent humidification board 32, it is predetermined. A gap X (for example, 1.5 mm) is secured (see FIG. 4A).

At this time, each humidifying plate 32 is fitted onto the second rib 38 of the front plate 30, and the corresponding boss 33 on the front plate 30 is fitted into the notch 45 of each humidifying plate 32. Here, as described above, the boss 33 bulges in an arc shape inward in the radial direction of the front plate 30, and the notch 45 is a circle bulging inward in the radial direction of the humidifying plate 32. Since it is formed in an arc shape, the boss 33 fitted in the notch 45 is accommodated in the notch 45 without a useless gap. Thereby, the humidification board 32 is hold | maintained by the front plate 30 in the state where several sheets overlapped. In this state, the notch 36 of each boss 33 communicates with each gap X (see FIG. 4A) in the adjacent humidifying plate 32.

  Next, the rear plate 31 is assembled from the rear side with respect to the front plate 30 in a state where the humidifying plate 32 is assembled.

It arrange | positions in the rear side of the storage part 34 so that the outer side surface (inner side surface in the storage part 34 of the boss | hub 33) may be followed (refer Fig.4 (a)). As a result, the front side portion of the inner side surface of the storage portion 34 of the boss 33 is recessed inward in the radial direction of the front plate 30 with respect to the rear side portion where the projections 44 are disposed, thereby forming a flow-down area 54 (FIG. 4). (See (a)). Further, in this state, each insertion hole 40 of the rear plate 31 faces the corresponding screw hole 43 in the front plate 30 from the rear side.

  Thereafter, the screw 50 is inserted into each insertion hole 40 from the rear surface side of the rear plate 31 and screwed into the corresponding screw hole 43. As a result, the front plate 30 and the rear plate 31 are integrated with the plurality of humidifying plates 32 sandwiched between the front plate 30 and the rear plate 31. At this time, the head of the screw 50 is accommodated in the corresponding recess 42 in the rear plate 31 and does not protrude from the rear plate 31.

  Finally, the shaft 51 is inserted into the cylindrical through hole 39 from the rear surface side of the rear plate 31. A disc-shaped cap 52 having a larger diameter than that of the shaft 51 is integrally provided at the rear end portion of the shaft 51, and the shaft inserted through the through hole 39 when the cap 52 is hooked on the rear surface of the rear plate 31. It is prevented that 51 falls out to the front side. The front end portion of the shaft 51 inserted through the through hole 39 is exposed from the front end surface of the through hole 39. Then, the cylindrical collar 53 is fitted on the exposed front end portion of the shaft 51, so that the shaft 51 is positioned so as not to come out of the through hole 39 and is fixed to the rear plate 31.

Thus, the assembly of the humidifying unit 20 is completed.
As shown in FIG. 3, the humidifying unit 20 assembled in this way supports the shaft 51 by supporting the front end portion (strictly, the collar 53) of the shaft 51 on the upper portion of the communication hole 14 in the partition wall 13. It is freely rotatable around the center. In this state, the lower part of the humidifying unit 20 (at least the humidifying plate 32) is immersed in the water accumulated in the tray 22 as described above.

  4A, the motor 60 is attached to the partition wall 13, and the gear 61 attached to the output shaft of the motor 60 is connected to the outer periphery of the first rib 37 in the front plate 30 of the humidifying unit 20. It meshes with the gear teeth on the surface. Therefore, when the motor 60 is driven, the gear 61 rotates in a predetermined direction, and accordingly, the entire humidification unit 20 is rotated in a predetermined direction, specifically, a clockwise direction when viewed from the back (FIG. 4 ( Rotate to b) (see dotted arrow). The rotation speed of the humidification unit 20 is about 2 rpm, for example. Here, the motor 60 is connected to a control unit 106 (control means) constituted by a microcomputer or the like, and the drive of the motor 60 is controlled by the control unit 106.

When the humidification unit 20 rotates in this way, the eight bosses 33 also rotate with the humidification unit 20. Below, with reference to FIG.4 (b), the mode of the one boss | hub 33 until the humidification unit 20 carries out 1 rotation is demonstrated.
First, when the boss 33 is immersed in the water of the tray 22, the water is stored up to the full through the notch 36 inside the boss 33 (see the boss 33 </ b> A). At this time, the portion around the boss 33 </ b> A in the humidifying plate 32 is also immersed in the water of the tray 22 and gets wet. This time is assumed to be when the humidifying unit 20 starts to rotate.

  Then, as the humidifying unit 20 rotates, the boss 33 immersed in the receiving tray 22 rises away from the water surface S of the receiving tray 22, whereby the water in the receiving tray 22 is pumped by the boss 33 (boss 33 B, boss 33C and boss 33D). Also, the portion of the humidifying plate 32 that has been soaked in the water of the tray 22 moves upward in the humidifying unit 20 and flows through the flow path 15 until the humidifying unit 20 makes a half turn (FIG. 2). (See the two-dot chain line arrow). As a result, the moisture adhering to the humidifying plate 32 becomes fine particles, rides on the cleaned air (in other words, humidifies the air), and is discharged to the outside from each outlet 9 (FIG. 2 (see the two-dot chain arrow). As a result, the room is humidified.

  As a result, the moisture from the humidifying plate 32 is almost lost until the humidifying unit 20 rotates 1/2. However, when the humidifying unit 20 rotates 1/2, the storage portion of the boss 33 at the uppermost position. In the inside of 34, the water pumped out from the saucer 22 remains (see the boss 33E). In particular, since the reservoir 34 in the boss 33E bulges downward, moisture remains reliably in the reservoir 34 of the boss 33. Therefore, when the humidifying unit 20 further rotates, the notch 36 of the boss 33 faces downward, and the moisture W remaining in the storage portion 34 is removed from the notch 36 by the capillary phenomenon between the adjacent humidifying plates 32. (See FIG. 4A) and supplied to the humidifying plate 32, and the humidifying plate 32 is wetted again (see the boss 33F). Here, the water in the storage part 34 enters the gap X from the notch 36 after being deviated from the rear side where the protrusions 44 are arranged to the front flow area 54 (see FIG. 4A).

  The portion of the humidifying plate 32 wetted by the water W in the storage portion 34 is cleaned until the humidifying unit 20 completes one rotation (see the boss 33G and the boss 33H) (see FIG. 2). (See the two-dot chain line arrow). Thereby, the water | moisture content adhering to the humidification board 32 is discharge | released indoors with the clean air similarly to until the humidification unit 20 carries out 1/2 rotation, and contributes to indoor humidification.

Thus, the humidifying plate 32 is wetted not only when it is immersed in the tray 22 but also when water is supplied by the boss 33, so that the humidifying plate 32 finishes one rotation, Many portions of the humidifying plate 32 that are wet can be secured, and the humidified plate 32 can be kept wet for a long time. Thereby, the humidification efficiency of the air cleaner 1 can be improved.
<Electrolytic water unit>
In the air cleaner 1, in the humidifying unit 20, as shown in FIG. 4, the electrolyzed water unit is placed in the inner space 57 of the humidifying plate 32 (strictly, the space surrounded by the second ribs 38 of the front plate 30). 70 is provided. As will be described later, the electrolyzed water unit 70 is for putting electrolyzed water on the air flowing through the flow path 15 after being purified by passing through the filter 11. Therefore, this air purifier 1 not only cleans the outside air taken in as described above with the filter 11, but also dissipates the electrolyzed water in the electrolyzed water unit 70 to sterilize and deodorize the outside air with this electrolyzed water. can do.

FIG. 6 is a perspective view of the electrolyzed water unit 70 viewed from the back side. FIG. 7 shows a state where the diffusion plate 72 and the gear 73 are removed in FIG. FIG. 8 shows a state where the diffusion plate 72 and the gear 73 are separated from each other in FIG. FIG. 9 is a diagram for explaining the dimensions of the rectangular hole 91 (small hole) of the diffusion plate 72.
As shown in FIG. 6, the electrolyzed water unit 70 includes a water receiving container 71, a diffusion plate 72, a gear 73, and an electrode unit 98.

  As shown in FIG. 7, the water receiving container 71 is long in the width direction, and integrally includes a front wall 74, a rear wall 75, a right wall 76, a left wall 77, and a bottom wall 78, and an upper surface thereof is opened. Box shape. The front wall 74 and the rear wall 75 extend along the width direction and face each other with a gap in the front-rear direction. The right wall 76 is constructed between the right end of the front wall 74 and the right end of the rear wall 75. The left wall 77 is constructed between the left end of the front wall 74 and the left end of the rear wall 75. The bottom wall 78 closes a portion surrounded by the front wall 74, the rear wall 75, the right wall 76, and the left wall 77 from below.

  A concave portion 79 that is long in the width direction and recessed toward the front side is formed in the lower portion of the front wall 74 at the center in the width direction. A portion corresponding to the concave portion 79 on the front surface of the front wall 74 protrudes to the front side compared to the other portions (see FIG. 3). In the right end portion of the front wall 74, an insertion hole 80 that penetrates the front wall 74 is formed at a position above the recess 79. In the front wall 74, a round through hole 81 is formed above the recess 79. On the front surface of the front wall 74, a tubular boss 82 is integrally provided so as to surround the through hole 81 and extend to the front side (see FIG. 3).

A central portion in the width direction at the upper end edge of the rear wall 75 is notched downward and is formed as a notch 83. A portion of the rear wall 75 that divides the lower side of the notch 83 bulges rearward and serves as a bulged portion 84. The upper end edge of the bulging portion 84 is inclined obliquely forward and downward (see FIG. 3).
In the bottom wall 78, an accommodation portion 85 that is depressed downward is formed at the right end portion (a portion that coincides with the insertion hole 80 in the width direction). A boss 86 protruding upward is integrally provided at a portion corresponding to the accommodating portion 85 in the bottom wall 78. In the bottom wall 78, a rib 87 protruding upward is integrally provided at the center in the width direction (a portion that coincides with the bulging portion 84 in the width direction). The rib 87 has a substantially semicircular arc shape that bulges to the rear side when viewed from the plane. The right end of the rib 87 extends to the right and then bends and is connected to the right end of the bulging portion 84. The left end portion of the rib 87 extends to the left side and then bends and is connected to the left end portion of the bulging portion 84. The upper end edge of the rib 87 is continuously inclined from the upper end edge of the bulging portion 84 and inclined obliquely forward and downward (see FIG. 3). Here, the concave portion 79 of the front wall 74 is located on the extended line of the upper edge of the rib 87 inclined obliquely downward to the front side (see FIG. 3). An opening 88 is formed in a portion of the bottom wall 78 surrounded by the rib 87 and the bulging portion 84. In the bottom wall 78, an annular rib 104 that slightly protrudes upward is formed on the front side of the rib 87 (see FIG. 3).

The rear portion of the left wall 77 is integrally provided with a guide 89 that is substantially U-shaped in cross section viewed from the width direction and extends to the lower left side.
The diffusion plate 72 has a thin disk shape made of resin. Specifically, as shown in FIG. 9, a cross-shaped through hole is formed at the center of the circle of the diffuser plate 72 to form a cross hole 90. The center of the cross hole 90 coincides with the circle center of the diffusion plate 72. In addition to the cross hole 90, a large number of rectangular holes penetrating the diffusion plate 72 are formed in the diffusion plate 72 to form a rectangular hole 91. These rectangular holes 91 surround the cross hole 90 and are arranged radially around the cross hole 90. Regarding the dimension of the rectangular hole 91, the dimension A in the radial direction of the diffusion plate 72 is set to be shorter than the dimension B in the circumferential direction of the diffusion plate 72. For example, the dimension A is about 5 to 6 mm. , About 9 to 10 mm. Further, the four corners of the rectangular hole 91 are rounded so as to have a radius of 1 mm, for example. The diffuser plate 72 is not limited to the above-described resin but may be composed of a nonwoven fabric or a metal net as long as the holes corresponding to the cross holes 90 and the rectangular holes 91 are formed.

  As shown in FIG. 8, the gear 73 has a disk shape having a central axis extending in the vertical direction, and second gear teeth 92 are formed on the outer peripheral portion thereof. Further, an upper end portion of a gear shaft 93 extending vertically as a rotation transmission shaft and a holding shaft is connected to a circular center position on the bottom surface of the gear 73. An annular rib 94 is integrally provided at the lower end portion of the gear shaft 93 so as to be fitted onto the gear shaft 93. On the outer peripheral surface of the gear shaft 93, four protrusions 95 that extend in the vertical direction and project outward in the radial direction of the gear shaft 93 are integrally provided at a portion below the rib 94. These protrusions 95 are equally spaced in the circumferential direction of the gear shaft 93 and form a cross when viewed from below. The upper end of the cross projection 96 is connected to the bottom surface of the rib 94.

The electrode unit 98 shown in FIG. 6 includes an electrode holder 99 and a pair of electrodes 100 (see FIG. 4). The electrode holder 99 is formed in a substantially rectangular parallelepiped shape, and a projection 101 protruding forward is formed at a front end portion thereof. The pair of electrodes 100 are supported by the electrode holder 99 and extend downward from the electrode holder 99.
Next, assembly of the electrolyzed water unit 70 will be described.

  First, as shown in FIG. 8, the diffusion plate 72 is inclined obliquely forward and downward with respect to the horizontal direction (front-rear direction) so that the front portion is positioned below the rear portion, and the diffusion in this state The cross projection 96 of the gear shaft 93 in a state extending along the vertical direction (vertical direction) is inserted into the cross hole 90 of the plate 72 from above, and the gear shaft 93 and the diffusion plate 72 are connected. And the gear 73 are integrated. Thereby, the diffusion plate 72 is held by the gear shaft 93 so as to be rotatable around the cross hole 90. Here, the size of the cross hole 90 is set such that the cross protrusion 96 is loosely fitted into the cross hole 90. Further, in a state where the cross projection 96 is inserted into the cross hole 90, the rib 94 is in contact with the diffusion plate 72 from above, whereby the diffusion plate 72 is positioned with respect to the gear 73.

  Next, the integrated diffusion plate 72 and gear 73 are accommodated from above in the water receiving container 71 as shown in FIG. As a result, as shown in FIG. 6, in the diffusion plate 72, the front end portion is fitted into the concave portion 79 of the front wall 74, and the rear side portion is formed between the upper end edge of the bulging portion 84 of the rear wall 75 and the bottom wall 78. It is mounted on the upper edge of the rib 87 (see also FIG. 7). Here, as described above, both the upper end edge of the rib 87 and the upper end edge of the bulging portion 84 are inclined obliquely forward and downward, and further, on the extension line of the upper end edge of the rib 87 (bulging portion 84), the front wall 74 recesses 79 are located (see FIG. 3). For this reason, the diffusion plate 72 accommodated in the water receiving container 71 maintains a state of being inclined obliquely forward and downward, just as when integrated with the gear 73 (see FIG. 7). At this time, in the diffusion plate 72, the rear portion (substantially rear half) faces the opening 88 (see FIG. 7) of the bottom wall 78 from above, and the front portion (substantially front half) is on the bottom wall 78. It faces the front side of the opening 88 (rib 87) from above (see FIG. 3). The gear 73 is rotatably supported by the bottom wall 78 when the lower end portion of the gear shaft 93 is fitted into the rib 104 of the bottom wall 78 from above (see FIG. 3). An arm 97 (see FIGS. 3 and 6) is attached to the front wall 74 of the water receiving container 71, a U-shaped notch is formed forward from the rear end of the arm 97, and the gear shaft 93 is The upper end portion of the gear shaft 93 is rotatably supported by the arm 97 by fitting the upper end portion into the notch.

  And the electrode unit 98 is accommodated in the accommodating part 85 (refer FIG. 7) of the bottom wall 78 of the water receiving container 71. FIG. In the electrode unit 98, the protrusion 101 of the electrode holder 99 is fitted from the rear side into the insertion hole 80 (see FIG. 7) of the front wall 74 of the water receiving container 71, and the boss 86 of the bottom wall 78 (see FIG. 7). Is positioned in the accommodating portion 85 by being inserted. Note that the lead wires (not shown) of the pair of electrodes 100 (see FIG. 4) are also inserted into the insertion holes 80 of the front wall 74 and connected to a main body power supply (not shown) outside the electrolyzed water unit 70. Yes.

Thus, the assembly of the electrolyzed water unit 70 is completed.
And the electrolyzed water unit 70 is supported by the partition 13 of the main body case 2 as shown in FIG. Specifically, in the partition wall 13, a first through hole 102 and a second through hole 103 are formed above the communication hole 14. The first through hole 102 is located above the second through hole 103. The boss 82 of the water receiving container 71 is inserted into the first through hole 102 from the front side, and a portion protruding forward from the front wall 74 of the water receiving container 71 corresponding to the recess 79 is the second through hole. The electrolyzed water unit 70 is positioned and fixed on the rear surface of the partition wall 13 by being inserted from the front side with respect to 103. In this state, as shown in FIG. 4A, the electrolyzed water unit 70 is surrounded by the second rib 38 of the front plate 30 in the humidifying unit 20 and disposed in a space above the shaft 51. Here, in the electrolyzed water unit 70, the second gear teeth 92 of the gear 73 mesh with the first gear teeth 55 at the upper end portion of the second rib 38, but the other portions are the humidifying unit 20. Not touching. The electrolyzed water unit 70 (at least the water receiving container 71) is in the same position as the flow-down area 54 of the humidifying unit 20 in the front-rear direction.

  Here, when the humidification unit 20 rotates as described above, as shown in FIG. 4B, the moisture W remaining in the storage portion 34 of the boss 33 (boss 33E) at the uppermost position flows into the flow-down area 54 ( The notch 36 in FIG. 4 (a)) penetrates into the gaps X (see FIG. 4 (a)) in the adjacent humidifying plates 32 and wets the humidifying plates 32. The moisture W descends to the inner peripheral edge of the humidifying plate 32 through a portion sandwiched between the first and second protrusions 47 and 48 on the front surface and the rear surface of the humidifying plate 32, respectively. And the water | moisture content W which reached | attained the inner periphery of the humidification board 32 falls via the passage hole 56 (refer FIG. 5) of the 2nd rib 38 from the inner periphery of the humidification board 32, and is located under the boss | hub 33E. It is received by the electrolyzed water unit 70 and collected in the water receiving container 71. Here, the first ridge 47 and the second ridge 48 guide the water W transmitted through the surface of the humidifying plate 32 to the electrolyzed water unit 70. Even if the moisture W that has reached the inner peripheral edge of the humidifying plate 32 through the surface of the humidifying plate 32 does not immediately fall and flows along the inner peripheral edge of the humidifying plate 32, the moisture W continues to be removed. Can be dropped into the electrolyzed water unit 70 at the cut 46. In the water dropped in this way, the water that has not reached the electrolyzed water unit 70 is received by the tray 22. Further, since the water accumulated in the boss 33 falls in the boss 33 toward the flow-down area 54 (see FIG. 4A) located above the electrolyzed water unit 70, this water is efficiently supplied to the electrolyzed water unit 70. Can be reached well.

  When the water level stored in the water receiving container 71 rises to the predetermined water level T in this way, the pair of electrodes 100 of the electrode unit 98 is immersed in the water stored in the water receiving container 71. The amount of water stored in the water receiving container 71 up to the predetermined water level T is, for example, 60 cc at the maximum, and when the water level exceeds the predetermined water level T, the excess water flows into the guide 89 and from the guide 89. It is returned to the tray 22.

Then, when a voltage is applied to the pair of electrodes 100 via lead wires (not shown), the water in the water receiving container 71 is electrolyzed to become electrolyzed water. More specifically, a voltage is applied to the pair of electrodes 100 through a lead wire (not shown) so that a predetermined current alternately flows so as to have opposite polarities. The water in the water receiving container 71 is electrolyzed. As water, tap water is usually used, and tap water contains chlorine. Therefore, the following electrochemical reaction occurs by electrolysis.
(Anode side)
4H ₂ O-4e ⁻ → 4H ⁺ + O ₂ ↑ + 2H ₂ O
2Cl ⁻ → Cl ₂ + 2e ⁻
H ₂ O + Cl ₂ ⇔HClO + H ⁺ + Cl ⁻
(Cathode side)
4H ₂ O + 4e ⁻ → 2H ₂ ↑ + 4OH ⁻
(Between electrode plates)
H ⁺ + OH ⁻ → H ₂ O
By the electrochemical reaction as described above, electrolyzed water containing hypochlorous acid (HClO) and active oxygen having a bactericidal action and a deodorizing action can be generated. By generating mist from the generated electrolyzed water as described later, electrolyzed water mist having a bactericidal action and a deodorizing action can be generated.

  Here, when water has accumulated in the water receiving container 71 up to the predetermined water level T described above, the diffusion plate 72 is obliquely forward and downward relative to the water surface of the water receiving container 71 as shown in FIG. It is inclined, and the front side portion (substantially front half) of the diffusion plate 72 is immersed in water (electrolyzed water) stored in the water receiving container 71. As described above, in the electrolyzed water unit 70, the second gear teeth 92 of the gear 73 mesh with the first gear teeth 55 of the second rib 38 of the humidifying unit 20. When rotating, the gear 73 receives the rotational force of the humidifying unit 20 and rotates.

  Then, as the gear 73 rotates, the diffusion plate 72 integrated with the gear 73 via the gear shaft 93 is inclined obliquely forward and downward by the gear shaft 93 as described above, and the front portion is the water receiving container. The cross hole 90 (see FIG. 6) is rotated about the rotation so as to synchronize with the rotation of the humidification unit 20 while maintaining the state of 71 immersed in water. Here, as described above, the cross projection 96 of the gear shaft 93 is loosely fitted into the cross hole 90, the front end portion of the diffusion plate 72 is fitted into the concave portion 79 of the front wall 74, and the rear side portions are both oblique. Since the rib 94 of the gear shaft 93 is in contact with the diffusion plate 72 from above, it is placed on the upper end edge of the bulging portion 84 inclined downward in the front side and the upper end edge of the rib 87. The plate 72 can rotate while being inclined obliquely forward and downward. And if the humidification unit 20 is rotated in this way, the diffusion plate 72 can also be rotated. Therefore, if there is a motor 60 that rotates the humidification unit 20, a mechanism (motor 60) only for rotating the diffusion plate 72 is provided. It is not necessary to provide a separate motor), the number of parts can be reduced, and maintenance of the humidifying unit 20 and the electrolyzed water unit 70 is facilitated.

  At the front side portion of the diffusion plate 72 immersed in the water (electrolyzed water) stored in the water receiving container 71, a film of electrolyzed water is formed in the rectangular hole 91 (see FIG. 6) due to surface tension, and is diffused in this state. By rotating the plate 72, the rectangular hole 91 with the electrolyzed water film stretched to the rear side of the diffusion plate 72, and from above to the opening 88 (see FIG. 7) of the bottom wall 78 of the water receiving container 71. opposite. That is, the diffusion plate 72 continuously takes out the electrolyzed water from the water receiving container 71 by rotating. Then, the rectangular hole 91 covered with the electrolytic water film flows from the lower side of the opening 88 in the air flowing through the flow path 15 (see the two-dot chain line arrow in FIG. 2) in the rear portion of the diffusion plate 72. The film is sequentially exposed to air, and the electrolyzed water film is broken into a mist and peeled off from the rectangular hole 91, so that the electrolyzed water is continuously diffused. Thereafter, the mist-like electrolyzed water (electrolyzed water mist) rises on the air flowing from the lower side of the opening 88 and passes through the gap X between the overlapped humidifying plates 32. (See the two-dot chain arrow in FIG. 2). At this time, since the rib 94 of the gear shaft 93 is in contact with the diffuser plate 72 from above as described above, there is no possibility that the diffuser plate 72 is lifted by the air flowing from below.

Conventionally, an electrolytic water mist is generated and diffused by high-frequency vibration generated by an ultrasonic vibrator using an expensive and complicated configuration such as an ultrasonic vibrator. According to the configuration, the electrolyzed water can be efficiently diffused, and the maintenance of the electrolyzed water unit 70 is easy. In particular, the electrolyzed water can be efficiently diffused by a simple configuration in which the rectangular hole 91 is provided in the diffuser plate 72 and the electrolyzed water film formed in the rectangular hole 91 is exposed to the air in the flow path 15. Here, if the rectangular hole 91 is formed with the above-described dimensions (dimension A: about 5 to 6 mm, dimension B: about 9 to 10 mm) (see FIG. 9), even if the air volume in the flow path 15 is small ( For example, the air volume when the air volume is large is 3.6 m ³ / min, whereas the air volume when the air volume is small is 0.6 m ³ / min). Can be dissipated. In addition, since the surface tension of the electrolyzed water adhering to the rectangular hole 91 is increased as the shape of the rectangular hole 91 is rounded, it is difficult to break the electrolyzed water into a mist.

Conventionally, there is a method of generating electrolyzed water mist by bubbling electrolyzed water separately from the ultrasonic vibrator, but in this case, there is a problem that the sound of bubbling electrolyzed water is noisy. However, in the system in which the diffusion plate 72 is rotated as in this embodiment, the electrolyzed water mist can be generated gently.
As described above, with reference to FIG. 4, this electrolyzed water unit 70 is a part of the water that has adhered to the humidifying plate 32 soaked in the receiving tray 22 and has fallen from the humidifying plate 32 without being used for humidification. Since electrolyzed water is generated from a small amount of water, the generation of electrolyzed water in the electrolyzed water unit 70 can be minimized. As a result, the amount of electrolyzed water collected in the water receiving container 71 of the electrolyzed water unit 70 becomes relatively small, so that when the air purifier 1 falls, a large amount of electrolyzed water leaks out and chlorine in the electrolyzed water There is no possibility of causing color fading or the like of indoor furniture due to the components. In addition, since the water collected in the saucer 22 is tap water, even if the water in the saucer 22 leaks, the above-described color fading will not occur.

  Further, since the electrolyzed water unit 70 generates electrolyzed water using a portion of the water for humidification stored in the tray 22, water is supplied only for the electrolyzed water generation in the electrolyzed water unit 70. It is not necessary to separately provide a configuration (such as a water supply tank), and the electrolyzed water unit 70 and the air purifier 1 can be combined with a simple configuration. Therefore, the mutual performance of the electrolyzed water unit 70 and the humidifying unit 20 is not hindered, the electrolyzed water unit 70 can generate a minimum amount of electrolyzed water, and the humidifying unit 20 provides sufficient humidification. The amount can be secured. Here, even if electrolyzed water is generated more than necessary in the water receiving container 71 of the electrolyzed water unit 70, an unnecessary amount of electrolyzed water is directed from the guide 89 (see FIG. 4B) toward the tray 22. When it falls and contacts the humidifying plate 32 in the middle, the humidifying plate 32 is sterilized by the chlorine component of the electrolyzed water. Further, in the electrolyzed water falling from the guide 89, the chlorine component is decomposed by adding kinetic energy due to the fall, so when this electrolyzed water reaches the receiving tray 22, the chlorine concentration is almost equal to the tap water in the receiving tray 22. It becomes the same level.

Since the electrolyzed water unit 70 is disposed in the inner space 57 of the annular humidifying plate 32, it is possible to reliably receive the water falling from the humidifying plate 32, and further, as with the humidifying plate 32, the flow path 15. Therefore, the electrolyzed water can be reliably put on the air in the flow path 15 without being scattered in an unnecessary direction.
Moreover, in the humidification board 32, since the 1st protrusion 47 and the 2nd protrusion 48 guide the water which propagates the surface of the humidification board 32 to the electrolyzed water unit 70 (refer FIG.4 (b)), the electrolyzed water unit 70 is shown. Can receive the water falling from the humidifying plate 32 more reliably.

Moreover, since the amount of water adhering to the humidifying plate 32 increases by providing the boss 33 as described above, the amount of water falling from the humidifying plate 32 to the electrolyzed water unit 70 also increases, and the amount of electrolyzed water generated Will also increase.
Here, the control unit 106 (see FIG. 4A) described above is configured so that the rotation direction of the humidifying unit 20 is switched to the one direction (a clockwise direction when viewed from the back) or the opposite direction. Operation can also be controlled. Thereby, if the humidifying plate 32 is rotated in one direction, the humidifying amount and the amount of electrolyzed water can be increased, and if the humidifying plate 32 is rotated in the opposite direction, the humidifying amount and the generated amount of electrolyzed water are decreased. Can be made. That is, the amount of humidification and the amount of electrolyzed water can be adjusted by switching the rotation direction of the humidifying plate 32.

  Further, the control unit 106 can also cause the motor 60 to operate intermittently. Therefore, even if the motor 60 can only be turned on / off and cannot adjust the speed (for example, an AC synchro motor), the control unit 106 causes the motor 60 to intermittently operate so that the humidifying plate 32 is simulated. Since it can be rotated at a low speed, the rotation speed of the humidifying plate 32 can be arbitrarily set. Thereby, the humidification amount depending on the rotation speed of the humidifying plate 32 and the generation amount of the electrolyzed water can be finely adjusted. For example, when it is desired that the amount of humidification and the amount of electrolyzed water generated be normal, the motor 60 may be operated normally, but when it is desired to reduce the amount of humidification and the amount of electrolyzed water generated, the motor 60 may be intermittently operated.

  The present invention is not limited to the embodiment described above, and various modifications can be made within the scope of the claims. For example, the air cleaner 1 in the said Example may be comprised as a humidifier which does not have an air purifying function.
