Then, the warm air contacts the humidifying filter that is rotating while being immersed in the water of the tank, and is humidified by the water attached to the humidifying filter, and is discharged out of the apparatus from the suction port.

Patent Document 1: Japanese Unexamined Patent Publication No. 2006-200762.

In the humidifier of patent document 1, the part immersed in the water of a water tank in a humidification filter rises first, while one humidification filter rotates, and when it reaches an upper limit, it descends and is immersed in the water of a water tank again. .

Thus, even when the humidification filter is rotated, since the warm air from the heater is constantly introduced to the humidification filter, the portion of the water tank attached to the humidification filter is at an early stage until the humidification filter finishes one rotation. There is a fear that the air will be dried and the air can no longer be humidified.

In this case, in a humidification filter, it becomes difficult to aim at the improvement of humidification efficiency.

This invention is made | formed based on such a background, and an object of this invention is to provide the humidifier which can aim at the improvement of a humidification efficiency, and the air cleaner provided with this humidifier.

The invention according to the second aspect of the present invention further includes a holding member which holds the plurality of humidifying plates in a state where they are stacked in a state of overlapping, and which rotates together with the humidifying plate, wherein the water supply part is provided on the holding member. It is a humidifier as described in the said 1st side characterized by the above-mentioned.

According to the third aspect of the present invention, a plurality of humidifying plates are rotated in a state where they are superimposed, and each of the opposing surfaces of the adjacent humidifying plates is provided with ribs facing each other. The part is a humidifier according to the first side, characterized in that it is a space surrounded by each of the opposing surfaces and the ribs of the neighboring humidifying plate.

According to a fourth aspect of the present invention, there is provided an air purifying means for purifying air flowing through the flow path; And a humidifier according to any one of the first side to the third side.

According to the invention of the first aspect, in the humidifier, the humidifying plate is rotated while a part of the reservoir is immersed in the water of the reservoir, thereby exposing the wet portion of the reservoir to water in the flow path to humidify the air.

And this humidifier is equipped with the water supply part which rotates with a humidification plate, drains the water of a water storage part, and supplies this water to a humidification plate. Therefore, since the humidification plate is wet not only when it is immersed in the water storage part but also when water is supplied by the water supply part, the humidification plate is moistened in the humidification plate over the period until the humidification plate finishes one revolution. A large number can be secured and the humidification plate can be kept wet. Thereby, the humidification efficiency of a humidifier can be improved.

According to the invention of the second aspect, since the water supply part is provided in a holding member that holds the humidifying plate in a state where a plurality of humidification plates are stacked and rotates together with the humidification plate, it is not necessary to separately install a part supporting the water supply part. Reduction of number can be aimed at.

According to the invention of the third aspect, in the humidifying plate rotating in a state where a plurality of sheets are overlapped, ribs facing each other are formed on the opposing surfaces of neighboring humidifying plates. And since the space enclosed by the opposing surface and rib of each adjacent humidification plate becomes a water supply part, it is not necessary to provide a water supply part as an independent component. Therefore, the number of parts can be reduced, the size of the device can be reduced, and the air can flow smoothly without alienating the water supply part in the flow path.

According to the invention of the fourth aspect, it is possible to provide an air purifier having a high commodity value provided with the humidifier according to any one of the first side to the third side.

In the boss 33, it becomes the storage part 34 expanded in circular arc shape in this way. An insertion / through hole 35 is formed in the rear end surface of the boss 33, and the boss 33 extends in the front-rear direction on the downstream side in the clockwise direction as viewed from the rear side. 36 is formed. The rear end of the cutout 36 and the insertion / through hole 35 are continuous. The inside of the boss 33 is exposed by the insertion / through hole 35 and the cutout 36. The boss 33 has a substantially C-shape in which the downstream side in the clockwise rotation is cut out from the rear face. Moreover, in the back surface of the front plate 30, the screw hole 43 is formed in the position to which each boss 33 was connected. The screw hole 43 faces the corresponding boss 33 and is exposed from the insertion / through hole 35 and the cutout 36.

On the rear surface of the front plate 30, an annular second rib 38 concentric with the front plate 30 is integrally formed. In detail, the 2nd rib 38 protrudes back from the front plate 30, and the circumferential edge of the front end part of the 2nd rib 38 is connected with respect to the inner peripheral edge of the front plate 30 over the whole perimeter. It is. A plurality of passage holes 56 are formed in the second rib 38 along the circumferential direction thereof, and these passage holes 56 communicate the inside and the outside in the radial direction of the second rib 38. have.

The back plate 31 has a centrality extending in the front-rear direction and has a thin disk shape in the front-rear direction. The outer diameter of the back plate 31 is almost the same as the outer diameter of the front plate 30.

In the circular center of the back plate 31, the cylindrical through-hole 39 is formed toward the front. In the outer circumferential edge portion of the back plate 31, a number (eight) of insertion and through holes 40 corresponding to the bosses 33 of the front plate 30 are formed. These insertion and through holes 40 are formed at equal intervals in the circumferential direction of the back plate 31 so as to follow the outer circumferential edge of the back plate 31, and penetrate the back plate 31.

In the front face of the back board 31, the protrusion 44 which protrudes in front is formed in the position adjacent to the inside of the back board 31 in the radial direction with respect to each insertion / through hole 40. As shown in FIG. The projection 44 is bulged in an arc shape in the radial direction of the back plate 31 along the circumferential edge of the insertion / through hole 40 as viewed from the front.

On the rear surface of the back plate 31, ribs 41 protruding backward to surround the insertion / through holes 40 are formed around each insertion / through hole 40. Inside, a recess 42 continuous to the corresponding insertion / through hole 40 is formed.

The humidifying plate 32 has a center line extending in the front-rear direction and is thin in the front-rear direction. The outer diameter of the humidifying plate 32 is almost equal to the outer diameter of the front plate 30, and the inner diameter (diameter of the inner circumferential edge) of the humidifying plate 32 is the diameter of the annular second rib 38 of the front plate 30. Greater than outer diameter

At the outer circumferential edge of the humidifying plate 32, a number (8) of cutouts 45 corresponding to the bosses 33 of the front plate 30 are formed. These notches 45 are formed at equal intervals in the circumferential direction of the humidification plate 32. Each notch 45 is formed in the shape of an arc which swells toward the inside of the humidifying plate 32 in the radial direction.

In each of the front and rear surfaces of the humidification plate 32, a convex portion 49 protruding outward in the front-rear direction is formed between the adjacent cutouts 45 in the circumferential direction of the humidification plate 32. It is. The convex part 49 is circular shape when seen from the front-back direction.

Next, the assembly of the humidification unit 20 is demonstrated.

First, as shown in FIG. 4, the front board 30, the humidification board 32, and the back board 31 are arranged concentrically from this front in this order. Here, the humidifying plate 32 is arranged in a state where a plurality of sheets (for example, 17 sheets) are superimposed in the front-rear direction (in FIG. 4, only one humidifying plate 32 is shown). Since the convex part 49 formed in each humidification plate 32 is interposed between the adjacent humidification plates 32, the adjacent humidification plate 32 has predetermined gap X (for example, 1.5 mm). ) Is secured (see Fig. 3 (a)).

The plurality of humidifying plates 32 are bonded to the front plate 30 from the rear side. At this time, each humidifying plate 32 is fitted outside the second rib 38 of the front plate 30, the boss 33 corresponding to the cutout 45 of each humidifying plate 32 in the front plate 30 Is embedded. Here, as described above, the boss 33 swells in an arc shape toward the inside of the front plate 30 in the radial direction, and the cutout portion 45 extends the inside of the humidifying plate 32 in the radial direction. Since it is formed in the circular arc shape which swells toward, the boss 33 inserted in the cutout part 45 enters in the cutout part 45 without unnecessary gap. As a result, the humidifying plate 32 is held in a state where the plurality of humidifying plates 32 are overlapped by the front plate 30. In this state, the notch part 36 of each boss 33 communicates with each clearance gap X (refer FIG. 3 (a)) in the adjacent humidification board 32. As shown in FIG.

Subsequently, the back plate 31 is pasted from the rear with respect to the front plate 30 in the state where the humidification plate 32 is pasted. At this time, the projection 44 of the back plate 31 is inserted and passed through the inside of this boss 33 via the insertion / through hole 35 of the corresponding boss 33 in the front plate 30 (Fig. 3 (c)), along the outer surface in the radial direction of the front plate 30 in the storage portion 34 of the boss 33 (inside surface of the storage portion 34 of the boss 33). So as to be disposed behind the reservoir 34 (see Fig. 3 (a)). Thereby, the front part of the inner surface in the storage part 34 of the boss 33 recesses inward in the radial direction of the front plate 30 rather than the rear part in which the projection part 44 was arrange | positioned, It becomes the flow down area | region 54 (refer FIG. 3 (a)). In this state, each insertion / through hole 40 of the back plate 31 faces the corresponding screw hole 43 in the front plate 30 from the rear side.

Thereafter, the screw 50 is inserted and passed through each insertion / passing hole 40 from the rear side of the rear plate 31 and twisted into the corresponding screw hole 43. As a result, the front plate 30 and the back plate 31 are integrated in a state where a plurality of humidifying plates 32 are sandwiched between the front plate 30 and the back plate 31. In addition, at this time, the head of the screw 50 enters into the corresponding recessed part 42 in the back board 31, and does not push out from the back board 31. FIG.

Finally, the shaft 51 is inserted and passed through the cylindrical through-hole 39 from the rear side of the back plate 31. At the rear end of the shaft 51, a disk-shaped cap 52 having a diameter larger than that of the shaft 51 is integrally provided, and the cap 52 is caught by the rear surface of the back plate 31, whereby a through hole is provided. The shaft 51 inserted and passed through the 39 is prevented from falling outward. The front end of the shaft 51 inserted and passed through the through hole 39 is exposed from the front end surface of the through hole 39. Then, the cylindrical collar 53 is fitted to the front end of the exposed shaft 51 so that the shaft 51 is positioned so that the shaft 51 does not come out of the through hole 39 and is fixed to the back plate 31. do.

The assembly of the humidification unit 20 is completed by the above.

The humidification unit 20 assembled in this way is, as shown in Fig. 3 (a), the front end of the shaft 51 (strictly the collar () in the upper portion of the communication hole 14 in the partition 13 53) is rotatable about the axis 51. In this state, the lower part of the humidification unit 20 (at least the humidification plate 32) is immersed in the water accumulated in the support dish 22 as mentioned above.

Moreover, the motor 60 is attached to the partition 13, and the gear 61 attached to the output shaft of the motor 60 has the 1st rib 37 of the front plate 30 of the humidification unit 20. It meshes with gear teeth on the outer circumference. Therefore, when the motor 60 is driven, the gear 61 rotates in a predetermined direction, and accordingly, the humidification unit 20 as a whole rotates in a predetermined one direction, in detail, in a clockwise rotation direction (Fig. 3 (b) dashed arrow). The rotation speed of the humidification unit 20 is about 2 rpm, for example. Here, a control unit 106 made of a microcomputer or the like is connected to the motor 60, 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 together with the humidification unit 20. Hereinafter, with reference to FIG.3 (b), the state of one boss 33 until the humidification unit 20 rotates one rotation is demonstrated.

First, when the boss 33 is immersed in the water of the support plate 22, water is collected inside the boss 33 via the cutout 36 (see boss 33A). At this time, the part around the boss 33A in the humidification plate 32 is also immersed in the water of the support plate 22, and is wet. This time is called the start of rotation of the humidification unit 20.

And as the humidification unit 20 rotates, the boss 33 immersed in the support plate 22 rises away from the water surface S of the support plate 22, and thereby the support plate 22 Of water is pumped out by the boss 33 (see boss 33B, boss 33C and boss 33D). In the humidifying plate 32, the wetted part is immersed in the water of the support plate 22 and moved upward in the humidifying unit 20 until the humidifying unit 20 rotates 1/2. Then, it is exposed to the air flowing through the flow path 15 (see the arrow of the dashed-dotted line in FIG. 2). As a result, the moisture adhering to the humidifying plate 32 becomes fine particles, which are loaded into the cleaned air (in other words, the air is humidified) and discharged to the outside from each outlet 9 (2 in FIG. 2). See arrows in dashed and dashed lines). As a result, the room is humidified.

As a result, almost no moisture is lost from the humidification plate 32 until the humidification unit 20 is rotated 1/2, but the boss at the highest point when the humidification unit 20 is rotated 1/2 is rotated. In the storage 34 of the storage 33, the water discharged from the support plate 22 remains (see boss 33E). In particular, since the reservoir 34 in the boss 33E swells downward, moisture remains reliably in the reservoir 34 of the boss 33. Therefore, when the humidification unit 20 further rotates, the cutout portion 36 of the boss 33 faces downward, and the water W remaining in the storage portion 34 is capillary phenomenon from the cutout portion 36. Is penetrated into each gap X (refer to FIG. 3 (a)) in the neighboring humidification plate 32, and supplied to the humidification plate 32, and the humidification plate 32 is again wetted (boss 33F). ) Reference). Here, the water of the storage part 34 is biased by the flow-down area 54 (refer FIG. 3 (a)) of the front from the back from which the protrusion part 44 was arrange | positioned, and then the clearance X from the notch part 36 Enter

And the part wetted by the moisture W of the storage part 34 in the humidification plate 32 is until the humidification unit 20 complete | finishes 1 rotation (boss 33G and boss 33H). Are exposed to a stream of clean air (see arrow in dashed line in FIG. 2). As a result, the moisture adhering to the humidifying plate 32 is released into the room together with the purified air as in the same way as the humidifying unit 20 is rotated 1/2, thereby contributing to the humidification of the room.

As described above, in the air cleaner 1, the boss 33 which rotates together with the humidification plate 32 to pump out the water of the support plate 22 and supplies the drained water to the humidification plate 32 is provided. It is installed. Therefore, the humidifying plate 32 is not only wetted by the base plate 22 but also wetted by the water supplied by the boss 33, and thus, until the humidifying plate 32 finishes one rotation. During the process, the wet part of the humidifying plate 32 can be secured a lot, and the humidifying plate 32 can be kept wet. In particular, as described above, since the moisture discharged from the support plate 22 remains reliably in the reservoir 34 of the boss 33E at the uppermost level when the humidifying plate 32 is rotated 1/2, the humidifying plate The water from the boss 33 to the humidification plate 32 is secured in a state where the dry part of the humidification plate 32 tends to be between 1/2 turn to one rotation. Is supplied. Therefore, the humidification efficiency of the air cleaner 1 can be improved.

Moreover, since the boss 33 is provided in the front plate 30 which rotates together with the humidification plate 32, holding the humidification plate 32 in the state which overlapped several sheets, the boss 33 is carried out. It is not necessary to separately install the parts for supporting the parts, so that the number of parts can be reduced.

In addition, by using the space for arranging the screw 50 (refer FIG. 4) which combines the front board 30 and the back board 31 in the humidification unit 20, the boss 33 is arrange | positioned without disturbing. can do.

Here, the control part 106 mentioned above may control operation | movement of the motor 60 so that the rotation direction of the humidification unit 20 may switch to the said one direction (clockwise direction seen from the back), or the reverse direction. Thereby, the humidification amount can be increased by rotating the humidification plate 32 in one direction, and the humidification amount can be reduced by rotating the humidification plate 32 in the opposite direction. That is, the amount of humidification can be adjusted by changing the rotation direction of the humidification plate 32.

In addition, the control unit 106 can also drive the motor 60 intermittently. Therefore, even if the motor 60 can only be ON / OFF control, even if it is a motor (for example, an AC synchronous motor) which can not adjust speed, the control part 106 may operate the motor 60. FIG. Since the humidification plate 32 can be spontaneously rotated at low speed by intermittent operation, the rotation speed of the humidification plate 32 can be set arbitrarily. As a result, the amount of humidification depending on the rotational speed of the humidifying plate 32 can be finely adjusted. For example, when it is desired that the humidification amount is as it is, the motor 60 may be normally operated. However, when the humidification amount is to be reduced, the motor 60 may be intermittently operated.

5 is a rear view of the humidifying plate to which the modified example is applied.

In the above embodiment, the boss 33 of the front plate 30 is moistened with the humidifying plate 32 using the water drained from the support plate 22.

In the following modified example, the structure which collects water in the humidification plate 32 itself is used, without collecting water in the boss 33. Therefore, in this modification, the structure (refer FIG. 3 and FIG. 4) which collects water to the boss 33 is abbreviate | omitted.

Specifically, as shown in FIG. 5, in each of the front side and the rear side of each humidifying plate 32 serving as the opposing surface of the neighboring humidifying plate 32, in the vicinity of each cutout part 45 in the front-rear direction. The 1st protrusion tank 63 and the 2nd protrusion tank 64 which protrude toward the outer side in this are formed. The first protrusion tank 63 and the second protrusion tank 64 function as ribs. The 1st protrusion tank 63 has decorated the edge of the notch 45. As shown in FIG. The second projection tank 64 is viewed from the rear side, and the humidification plate 32 is continuously formed from a portion on the upstream side in the clockwise direction (see the dotted arrow in the drawing) in the corresponding first projection tank 63. Extends in the clockwise direction along the inner circumferential edge of the humidifying plate 32 while gently bending to the inner circumferential edge. Thereby, the 1st protrusion tank 63 and the 2nd protrusion tank 64 have comprised substantially V shape which cut | disconnected downstream in the clockwise direction. In addition, instead of the 1st protrusion tank 63 and the 2nd protrusion tank 64, the substantially U-shaped 3rd protrusion tank 67 (refer a dotted line part) in which the downstream in the clockwise direction was cut off is provided, You may also The 3rd protrusion tank 67 may be in the position away from the notch 45.

As described above, when a plurality of such humidifying plates 32 are overlapped in the front-rear direction (refer to FIG. 3 (a)), in the adjacent humidifying plates 32, the first side of the front humidifying plate 32 is formed. 1 protrusion tank 63 opposes (details in contact with) corresponding 1st protrusion tank 63 in the front surface of the humidification board 32 of the back, and is made of the back of the humidification board 32 of the front. The 2 protrusion tank 64 opposes (contacts) the corresponding 2nd protrusion tank 64 in the front surface of the humidification board 32 of the back side. Thereby, in the neighboring humidification plate 32, two 1st protrusion tank 63 which opposes (contacts) mutually, the two 3rd protrusion tank 64 which opposes (contacts) mutually, and the front Surrounded by the rear surface of the humidifying plate 32 and the front surface of the rear humidifying plate 32, a substantially V-shaped space 65 is formed in which the downstream side in the aforementioned clockwise rotation direction is opened. Since 65 plays the role of the boss 33 mentioned above, independent components like boss 33 do not need to be provided. Therefore, it is possible to reduce the number of parts, to downsize the device, and to allow air to flow smoothly in the flow path 15.

Moreover, since the structure (space 65) corresponded to the boss 33 is formed only by superimposing the humidification board 32 in this way, compared with the said Example which has the boss 33, of the humidification unit 20 It is easy to disassemble, assemble and maintain.

In the following, the state of one space 65 until the humidification unit 20 in which the space 65 is formed is rotated by one will be described.

First, when the space 65 is immersed in the water of the support dish 22, the space 65 is filled with water through the open part (opening part 66) in the downstream side in a clockwise rotation direction. Can be collected (see space 65A). At this time, the part around the space 65A in the humidification plate 32 is also immersed in the water of the support plate 22, and wet.

And as the humidification unit 20 rotates, the space 65 immersed in the support dish 22 rises away from the water surface S of the support dish 22, and thereby the support dish 22 Water is pumped out by the space 65 (see space 65B, space 65C and space 65D). Also. In the humidification plate 32, the humidifying unit 20 is wetted by the water of the support plate 22 until the humidification unit 20 is rotated 1/2 in the same manner as in the above-described embodiment. In this case, the water adhering to the humidifying plate 32 becomes fine particles, is discharged to the outside by being cleaned in air, and the room is humidified.

For this reason, while the humidification unit 20 rotates 1/2, the moisture is almost lost from the humidifying plate 32, but the moisture remains in the space 65 (see space 65D), As the humidification unit 20 is rotated 1/2, water in the space 65 passes from the opening 66 to each gap X (see Fig. 3 (a)) in the neighboring humidifying plate 32. It penetrates and is supplied to the humidification plate 32, and the humidification plate 32 is wetted again (refer to space 65E). When the humidification unit 20 further rotates, the opening 66 of the space 65 faces downward, and the water W of the space 65 remains in the gap X from the cutout 36. Enter without (see space 65F).

And the part wetted by the moisture W of the space 65 in the humidification plate 32 is until the humidification unit 20 complete | finishes one rotation (space 65G and space 65H). Exposure to a stream of clean air (see arrow in dashed line in FIG. 2). As a result, the moisture adhering to the humidifying plate 32 is released into the room together with the purified air as well as until the humidifying unit 20 is rotated 1/2, thereby contributing to the humidification of the room.

This invention is not limited to embodiment described above, A various change is possible in a claim. For example, the air cleaner 1 in the said embodiment may be comprised as a humidifier which does not have an air cleaning function.
