  Hereinafter, the humidifying device of the present invention will be described in detail with reference to the illustrated embodiments.

  FIG. 1 shows a perspective view of a humidifier according to an embodiment of the present invention. As shown in FIG. 1, the humidifier includes a casing 1, and the casing 1 includes a casing body 2 and a front panel 3 that is detachably attached to the casing body 2. Suction ports 5, 5 (only one is shown in FIG. 1) are provided on both side surfaces of the casing 1, and a blower outlet 6 is provided at the rear of the upper surface of the casing 1.

  FIG. 2 shows a longitudinal sectional view of the humidifier. The same reference numerals are assigned to the same components shown in FIG.

  As shown in FIG. 2, the humidifying device includes an air purifying filter unit 30, a humidifying mechanism 40, and a fan 20 driven by a fan motor 21 in the casing 1 in order from the front side. In addition, although not shown in FIG. 2, the water tank 10 is arrange | positioned to the side of the humidification mechanism 40 (refer FIG. 4C). In FIG. 2, reference numeral 71 denotes a power supply printed board, 72 denotes an operation control printed board, 73 denotes a display printed board, 74 denotes a dust sensor, 75 denotes a spare filter, and 80 denotes a control unit.

  The air purification filter unit 30 is generally rectangular in front view. Moreover, the lower part of the air purification filter unit 30 and the humidifying mechanism 40 overlap in the front-rear direction. Further, the air purifying filter unit 30 and the humidifying mechanism 40 are arranged so as to overlap at least a part of the bell mouth 23 of the fan 20, that is, arranged so as to cover at least a part of the bell mouth 23. The noise from is reduced.

  The air purifying filter unit 30 also collects a pre-filter 31 for collecting large dust, pet hair, etc., an ionization unit 32 for charging the dust, dust, etc., and charged dust, dust, etc. For example, a dust collecting filter 33 made of a pleated filter and a deodorizing filter 34 for collecting malodorous components such as cigarette odor and pet odor are included. The pre-filter 31, the ionization unit 32, the dust collection filter 33, and the deodorization filter 34 are arranged in a substantially straight line in order from the front side of the casing 1. In addition, since the dust collection filter 33 is a pleated filter with a large surface area, ventilation resistance can be reduced.

  As shown in FIG. 2, the deodorizing filter 34 and the dust collection filter 33 of the air cleaning filter unit 30 are overlapped on the entire bell mouth 23 of the fan 20, while the humidifying mechanism 40 is a lower part of the bell mouth 23. However, it does not overlap the upper part of the bell mouth 23. Therefore, the air flowing through the non-humidifying passage 51 extending from the upper portion of the deodorizing filter 34 to the upper portion of the bell mouth 23 does not pass through the humidifying mechanism 40, so that the ventilation resistance of the air flowing through the non-humidifying passage 51 can be reduced. In particular, when only the air cleaning operation is performed without performing the humidifying operation, a sufficient air volume (air amount) can be secured.

  On the other hand, the humidification passage 52 from the lower part of the deodorizing filter 34 of the air purification filter unit 30 to the humidifying mechanism 40 and the upper part of the bell mouth 23 of the fan 20 from the upper part of the deodorizing filter 34 are not. The humidifying passage 51 is partitioned by a partition plate 50.

  This partition plate 50 prevents the flow of air from the humidification passage 52 to the non-humidification passage 51, that is, prevents the flow of air from the humidification passage 52 to bypass the humidification mechanism 40, and flows into the humidification passage 52. Most of the water flows through the humidifying mechanism 40 so that a large amount of humidification can be obtained.

  Further, the partition plate 50 extends from the deodorizing filter 34 of the air purification filter unit 30 to the vicinity of the fan 20. Alternatively, although not illustrated, the partition plate 50 may extend from the deodorizing filter 34 to the vicinity of the bell mouth 23. Thereby, the turbulent flow due to the collision between the humidified air exiting the humidifying mechanism 40 and the non-humidified air flowing through the non-humidified passage 51 is prevented, the ventilation resistance is reduced, and the noise is reduced. .

  FIG. 3 shows an exploded perspective view of the humidifying mechanism 40 of the humidifying device.

  As shown in FIG. 2, the geared motor 70 is disposed on the humidifying mechanism 40 so as not to overlap the air flow direction so that the geared motor 70 does not interfere with the air flow through the humidifying mechanism 40. . Thus, the amount of air passing through the humidifying mechanism 40 can be increased to increase the amount of humidification.

  Further, the twelve buckets 200 are configured to pour water pumped up by the lower water tray 90 (shown in FIG. 4C) with the rotation of the revolving frame 100 into the humidifying member 300.

  As described above, the humidifying member 300 is sandwiched and fixed between the revolving frame 100 and the holding frame 400.

  In this embodiment, the twelve buckets 200 are attached to the revolving frame 100. However, any one of them may be provided on either the revolving frame or the holding frame. May be set as appropriate according to the conditions, and at least two or more.

  4A shows a perspective view of the humidifying mechanism 40 in an assembled state, and FIG. 4B shows a side view of the humidifying mechanism 40. 4A and 4B, the same reference numerals are assigned to the same components shown in FIG.

  FIG. 15C shows a rear view of the presser frame 400 of the humidifying mechanism 40 as viewed from the downstream side, and the same reference numerals are given to the same components shown in FIG. 15A.

(Single shaft unit)
FIG. 16 shows a side view of the shaft portion 500 of the humidifying mechanism 40. As shown in FIG. 16, the main portion 501 that penetrates the revolving frame 100, the humidifying member 300 (shown in FIG. 3), and the holding frame 400, and the first provided on the upstream side (left side in FIG. 16) of the main portion 501. , And a second annular groove 503 provided on the downstream side of the main portion 501 (the right side in FIG. 16).

  A bearing portion (not shown) of a first support leg 601 as an example of a support member erected upward from the water tray 90 (shown in FIG. 4C) in the annular groove 502a of the first annular groove portion 502. Fits freely. In addition, a bearing portion (not shown) of a second support leg 602 as an example of a support member erected upward from the water tray 90 is rotatable in the annular groove 503a of the second annular groove portion 503. Mating.

  According to the humidifier of the above configuration, as shown in FIGS. 7A and 8A, in the humidifying mechanism 40, the rotation of the swivel frame 100 and the gear 110 that is a rotational force transmitting portion provided on the outer periphery of the swivel frame 100 is performed. By arranging the bucket 200 that pours the pumped water into the humidifying member 300 on the same plane, the axial dimension of the humidifying mechanism 40 can be reduced and the depth of the apparatus main body can be reduced.

  The rotational force transmission unit is not limited to the gear 110, and a transmission mechanism such as a roller that transmits rotational force may be used.

  Further, in the humidifying mechanism 40, the gear 110 provided on the outer periphery of the revolving frame 100, the humidifying member 300 attached to the revolving frame 100, and the water pumped up as the revolving frame 100 rotates is supplied to the humidifying member 300. By arranging the pouring bucket 200 on the same plane, the axial dimension of the humidifying mechanism 40 can be made thinner.

  Further, by using the gear 110 as the rotational force transmitting portion, the driving force from the geared motor 70 can be reliably transmitted to the turning frame 100.

  Further, by arranging the bucket 200 on the radially inner side of the gear 110 of the revolving frame 100 and disposing the humidifying member 300 on the radially inner side of the bucket 200, the gear 110, the humidifying member 300, and the bucket 200 of the revolving frame 100 are arranged. Are arranged at optimal positions, the axial dimension of the humidifying mechanism 40 can be reliably reduced.

  In the shaft portion 500 that rotatably supports the revolving frame 100, the axial dimension of the protruding portion from the humidifying member 300 on the downstream side of the protruding portion from the humidifying member 300 on the upstream side of the air flow supplied by the fan 20 is set. It is shortened. Specifically, the axial length L2 of the portion protruding downstream from the humidifying member 300 is shortened with respect to the axial length L1 of the portion protruding upstream from the humidifying member 300. Accordingly, by pouring water from the bucket 200 to the upstream side of the humidifying member 300, the portion protruding in the axial direction except for the shaft portion on the downstream side of the humidifying mechanism 40 can be eliminated. The depth of the support leg that supports 500 can be shortened, and the axial dimension of the humidifying mechanism 40 can be made thinner.

  Further, using a humidifying member 300 having a thick disc portion 301 and a thin flange portion 302 provided on the outer peripheral side of the disc portion 301, a step between the flange portion 302 and the disc portion 301 of the humidifying member 300. By providing the spout 202 in the bucket 200 so as to face the portion, the opening area of the spout 202 that pours water from the bucket 200 to the humidifying member 300 is reduced even if the axial dimension of the humidifying mechanism 40 is reduced. The surface area of the humidified member 300 facing the pouring spout 202 can be increased.

  Further, according to the humidifying device, as shown in FIGS. 7A and 8A, the axial dimension of the humidifying mechanism 40 is reduced by the humidifying mechanism 40 in which the bucket 200 is sandwiched between the revolving frame 100 and the holding frame 400, The thickness of the apparatus main body can be suppressed, and as shown in FIGS. 9A and 9C, water is introduced into the bucket 200 through the water supply holes 101a and 101b provided in the swivel frame 100. Even with a configuration sandwiched between the presser frames 400, a sufficient amount of water can be supplied to the bucket 200. Therefore, it is possible to obtain a sufficient amount of humidification while reducing the axial dimension of the humidifying mechanism 40 and suppressing the thickness of the apparatus main body.

  Further, in the humidifying mechanism 40 having a configuration in which the water supply holes 101a and 101b are provided in the revolving frame 100, the gear 110, the humidifying member 300, and the bucket 200 provided on the outer peripheral portion of the revolving frame 100 are arranged on the same plane. By doing so, the axial dimension of the humidification mechanism 40 can be made thinner.

  Further, the water supply holes 101a and 101b partially overlap the outer side in the radial direction of the opening of the pumping port 201 of the bucket 200 so that the bucket 200 positioned below the swivel frame 100 during the swivel motion is placed. Since at least a part of the water supply holes 101a and 101b is located at a position lower than the upper edge of the pumping port 201, the water supply holes are not made larger than necessary.

  Further, the water supply holes 101a and 101b overlap with the radially outer edge of the opening of the pumping port 201 of the bucket 200, so that it is higher than the lower edge of the pumping port 201 of the bucket 200 positioned below the swing frame 100 during the swing motion. Since at least some of the water supply holes 101a and 101b are located at the position, water can be reliably guided to the pumping port 201 of the bucket 200 via the water supply holes 101a and 101b.

  Further, by arranging the water supply holes 101a and 101b in the vicinity of the opening of the pumping port 201 of the bucket 200, water can be guided to the pumping port 201 of the bucket 200 through the water supply holes 101a and 101b at the shortest distance.

  Further, by providing the water supply holes 101a and 101b on the upstream side of the revolving frame 100, it is possible to prevent water from flying downstream through the water supply holes 101a and 101b.

  When the pressing frame is arranged on the upstream side and the swivel frame is arranged on the downstream side, it is possible to prevent water splashing to the downstream side by providing a water supply hole on the upstream side of the pressing frame.

  Moreover, according to the said humidifier, as shown to FIG. 12A and FIG. 12B, the rear edges 220 and 230 of the spout 202 opened to the radial inside of the turning motion of the bucket 200 are defined by the bent line. From the trailing edge 220, which is defined by a bent line when the water is discharged radially inward from the spout 202 at the inclination of the bucket 200 in the vicinity of the upper end of the swinging motion while the bucket 200 performs the swinging motion. A small amount of water is drained first from the rearmost part of 230 (eg 220a), then water is drained from a part before the subsequent part (eg 220b), and water is gradually drained, A large amount of water is not discharged at once. Therefore, even when the humidifying member 300 is dry, water can penetrate into the humidifying member 300. Thus, since water is gradually discharged from the spout 202, a film of water is formed on the whole spout 202 by surface tension, and this water film is broken, and a large amount of water becomes a lump at a stretch. The water droplets are never discharged from the humidifying member 300 to the downstream side because they are not discharged from the spout 202. Thereby, water splash can be prevented.

  Further, the rear edges 220 and 230 of the spout 202 of the bucket 200 are arranged so that the upstream portion of the rear edges 220 and 230 of the spout 202 is the rear edge of the spout 202 with respect to the air flow passing through the humidifying member 300. Since the air is retreated so that water is discharged earlier than the downstream portion, the upstream portion of the humidifying member 300 is applied with water earlier than the downstream portion with respect to the air flow. The portion on the side is moistened first, and then water is applied to the portion on the downstream side where the moisture is transmitted from the portion on the upstream side. Therefore, even in an environment where the humidifying member 300 is dry, the downstream portion of the humidifying member 300 is wetted from the upstream side, and then the wet downstream portion is watered. In this case, water can smoothly permeate into the humidifying member 300, and the water splash that the water droplets fly to the downstream side of the humidifying member 300 can be effectively prevented.

  Also, as shown in FIG. 12A, the rear edge 220 of the spout 202 of the bucket 200 is bent in a step shape, so that water is gradually applied to the humidifying member 300 to prevent water splashing with a simple structure. be able to.

  Also, as shown in FIG. 12B, the rear edge 230 of the spout 202 of the bucket 200 is bent in a saw blade shape, so that water is gradually applied to the humidifying member 300 to prevent water splashing with a simple structure. can do.

  In the above embodiment, the gear 110 on the outer periphery of the swivel frame 100, the bucket 200 attached to the swivel frame 100, and the humidifying member 300 are arranged on the same plane to achieve a reduction in thickness. The bucket and the gear may be arranged on the same plane except for the humidifying member.

  Further, according to the humidifying device, when the bucket 200 rotates by the rotation of the revolving frame 100 and is located near the top of the humidifying member 300, the water in the bucket 200 flows out from the spout 202 and is humidified. It takes. At this time, as shown in FIGS. 5B and 13B, a wall portion 106a is provided in the revolving frame 100 in the vicinity of the pumping port 201 that opens forward in the revolving direction of the bucket 200, and the radially outer end of the wall portion 106a Since the pumping port 201 is located on the radially outer side than the inner surface on the radially inner side, it is possible to prevent the water to flow out from the spout 202 from leaking out of the pumping port 201. Therefore, a target amount of water can be supplied to the humidifying member 300 without reducing the water that should flow out of the spout 202.

  Further, as shown in FIG. 13B, the wall portion 106a is separated from the pumping port 201 by engaging the engaging portion 207 of the bucket 200 with the wall portion 106a that also serves as the engaging portion of the swivel frame 100. Can be prevented. That is, the wall 106a can be reliably positioned in the vicinity of the radially inner surface of the pumping port 201.

  Further, as shown in FIG. 5B, when the bucket 200 is swung and positioned near the top of the humidifying member 300, the spout 202 is provided behind the pumping port 201 in the swiveling direction of the bucket 200. It becomes difficult for the water in 200 to reach the pumping port 201. Therefore, it is possible to enhance the effect of preventing the water that should flow out from the spout 202 from leaking out from the pump 201.

  Further, when the bucket 200 is swung and positioned near the top of the humidifying member 300, the spout 202 is opened radially inward, so that the water in the bucket 200 easily flows out of the spout 202. Accordingly, it is difficult for water to remain in the bucket 200.

  In addition, in the said embodiment, the humidification mechanism 40 had the holding frame 400, However, You may make it not have a holding frame.

  Moreover, although the wall part 106a of the revolving frame 100 also serves as a locking part that locks the bucket 200, the wall part 106a may not also serve as a locking part that locks the bucket.

  Moreover, although the said gear 110, the humidification member 300, and the bucket 200 were arrange | positioned on the same plane, you may make it not arrange | position a gear, a humidification member, and a bucket on the same plane. For example, the gear and the humidifying member may be arranged on the same plane, and the gear and the bucket may be arranged so as to overlap in the axial direction.

  Moreover, although the said spout 202 was opened to radial inside, you may make it open to the upstream with respect to the air flow produced, for example by the fan.

  Further, according to the humidifier, the water supply unit (bucket 200) supplies water to the humidifying member 300 in order to humidify the air flow generated by the fan 20. At this time, since the net 404 (FIG. 15A, FIG. 15C) is arranged on the downstream side with respect to the air flow of the humidifying member 300, the water applied to the humidifying member 300 is blown away and the downstream side of the humidifying member 300. It is possible to prevent other members from being applied.

  Moreover, as shown in FIG. 3, since the net | network 404 is arrange | positioned in the downstream of the humidification member 300, it can prevent that the air volume which passes the humidification member 300 falls.

  Moreover, since the net | network 404 is arrange | positioned in the downstream of the said humidification member 300, it can also prevent that the humidification amount falls, without reducing the area which contributes to humidification in the humidification member 300. FIG.

  On the other hand, when a wall is provided on the downstream side of the humidifying member, for example, water applied to the humidifying member can be prevented from being blown to the downstream side of the humidifying member, but the amount of air passing through the humidifying member is reduced. The area that contributes to humidification in the humidifying member decreases and the humidification amount decreases.

  In addition, since the maximum hole of the net 404 is smaller than the maximum hole of the humidifying member 300, it is possible to reliably prevent water applied to the humidifying member 300 from being blown to the downstream side of the humidifying member 300.

  Further, as shown in FIGS. 15A to 15C, since the net 404 is integrally formed with the holding frame 400, the number of parts and the number of assembly steps can be reduced, and the manufacturing cost can be reduced.

  Moreover, in the said embodiment, although the gear 110, the humidification member 300, and the bucket 200 were arrange | positioned on the same plane, it is made to arrange | position a gear and a bucket on the same plane except a humidification member. Also good.

  Moreover, in the said embodiment, although the largest hole of the net | network 404 was made smaller than the largest hole of the humidification member 300, you may make it the same size as the largest hole of a humidification member.

  In the above embodiment, the net 404 and the presser frame 400 are integrally formed. However, the net and the presser frame may be formed separately. In this case, a net formed separately from the holding frame may be attached to, for example, a bell mouth on the downstream side of the humidifying member.

  Further, according to the humidifying device, as shown in FIG. 7B, the drainage port 110b is provided on the downstream side of the bottom of the tooth groove of the gear 110 provided on the outer peripheral portion of the swivel frame 100 of the humidifying mechanism 40. The water adhering to the tooth gap of 110 flows from the upstream side to the downstream side of the air flow supplied from the fan 20 when the tooth tip of the gear 110 is substantially upward in the vertical direction, and then the bottom of the tooth gap. It falls to the inside of the humidifying mechanism 40 from the drain port 110b provided on the downstream side of the. Therefore, water adhering to the gear 110 provided on the outer peripheral portion of the swivel frame 100 can be drained efficiently, and water splash can be effectively prevented.

  Further, as shown in FIG. 7B, the gear 110 of the swivel frame 100 is provided with an inclined surface 110a that is inclined from the upstream side toward the downstream side and from the tooth tip toward the tooth root, whereby the tooth groove of the gear 110 is provided. Since the water adhering to is guided to the drain port 110b along the inclined surface 110a from the upstream side to the downstream side of the air flow supplied from the fan 20, the water adhering to the gear 110 can be drained efficiently.

  In addition, as shown in FIG. 7B, by providing a drain outlet 110b at a part of the bottom of the tooth gap of the gear 110 of the swivel frame 100, a drain outlet is provided at the entire bottom of the gear groove of the gear 110. Also, the strength of the gear 110 can be increased.

  In the above-described embodiment, the drain port 110b is provided in a part of the swivel frame 100 on the downstream side of the bottom of the tooth gap of the gear 110. A drain outlet may be provided.

  Further, according to the humidifier, as shown in FIGS. 7A, 7B, 8A, and 8B, the gear 110, the bucket 200, and the humidifying member 300 on the outer peripheral portion of the swivel frame 100 are arranged on the same plane. Therefore, the humidification mechanism 40, and thus the axial dimension of the humidifier can be reduced, and the bucket 200 is fixed by being sandwiched between the revolving frame 100 and the holding frame 400. Can fix the separate bucket 200 to the revolving frame 100 easily and reliably.

  Further, a spout 202 that opens radially inward of the turning motion of the bucket 200 is engaged with a locking portion (between the ribs 106 of the turning frame 100) provided in the turning frame 100 in the circumferential direction of the turning motion. Thus, the bucket 200 can be easily and reliably positioned in the circumferential direction. Further, since the spout 202 is engaged with the engaging portion provided in the swivel frame 100 in the circumferential direction of the swivel motion, the spout 202 can be used as a positioning member.

  In addition, you may provide the latching | locking part which engages the spout 202 of the bucket 200 in the circumferential direction of turning motion in the holding frame 400. FIG.

  Further, as shown in FIG. 8B, the back portion of the bucket 200 is narrower in the radial direction of the turning motion of the bucket 200 than the pumping port 201, and the holding frame is inserted into the engagement hole 101 c of the turning frame 100 near the back portion. Since the engaging claws 410 provided on the engaging portion 400 are engaged, the space generated by the narrowing of the inner portion of the bucket 200 is effectively used to provide the engaging hole 101c of the revolving frame 100 and the holding frame 400. The swivel frame 100 and the pressing frame 400 can be easily fixed by engaging the engaging claws 410 thus formed.

  Further, as shown in FIGS. 10A to 10C, a flange 204 is provided in the inner part of the bucket 200 that is narrower in the radial direction of the turning motion of the bucket 200 than the pumping port 201 of the bucket 200. 100 is locked in the axial direction in a recess (between the protrusion 106b of the swivel frame 100 and the through hole 120 shown in FIG. 13B), the flange 204 is attached when the bucket 200 is mounted on the swivel frame 100. The bucket 200 can be easily positioned and temporarily secured by being axially locked to the recess.

  Further, as shown in FIGS. 7B and 8B, a rib 420 as an example of a protrusion provided on the revolving frame 100 so as to protrude in the axial direction is in contact with the bucket 200 from the axial direction, and the axial direction of the bucket 200 is increased. Since the position is determined, the position of the bucket 200 in the axial direction can be determined reliably and can be fixed securely.

  Further, by appropriately setting the length of the protrusion, the position of the bucket 200 in the axial direction can be arbitrarily determined, and the degree of freedom is increased.

  Further, the ribs 420 as the protrusions are in contact with the downstream surface of the bucket 200 with respect to the air flow, and the bucket 200 is arranged with respect to the humidifying member 300 so as to be biased toward the upstream side of the air flow passing through the humidifying member 300. Therefore, water can be poured from the bucket 200 to the upstream side of the humidifying member 300 to prevent water splashing from the humidifying member 300 to the downstream side of the air flow.

  In the above embodiment, the ribs 420 as the protrusions are provided on the revolving frame 100. However, when the holding frame is arranged on the upstream side and the turning frame is arranged on the downstream side, the revolving frame 100 protrudes in the axial direction. A protrusion provided on the abutting portion may be brought into contact with the bucket from the axial direction to determine the position of the bucket in the axial direction.

  Further, according to the humidifier, as shown in FIGS. 7B and 8B, the gear 110, the bucket 200, and the humidifying member 300 on the outer peripheral portion of the revolving frame 100 are arranged on the same plane. 40, and thus the axial dimension of the humidifier can be reduced, and as shown in FIG. 13B, the outer peripheral portion of the bucket 200 is in contact with the inner peripheral surface of the gear 110, and the bucket 200 is moved to the revolving frame 100. Therefore, the size of the bucket 200 can be increased, and the pumping amount can be increased by increasing the number of buckets.

  Further, as shown in FIG. 13B, the outer peripheral portion (the outer peripheral surface 210 side) of the bucket 200 is in contact with the inner peripheral surface 111 of the gear 110, and the wall (rib 106) provided on the swivel frame 100 is used. Since the inner peripheral portion is constrained, the bucket 200 can be easily and reliably fixed by elastically pressing the bucket 200 toward the inner wall in the radial direction by the elasticity of the gear 110.

  Further, as shown in FIG. 7B, since a part of the tooth bottom of the gear 110 is a through hole (drain port 110b), the flexibility of the gear 110 is further improved, the elasticity is further improved, and the more reliable. In addition, the bucket 200 can be fixed.

  In the above embodiment, the ribs 420 as the protrusions are provided on the revolving frame 100. However, when the holding frame is arranged on the upstream side and the turning frame is arranged on the downstream side, the revolving frame 100 protrudes in the axial direction. A protrusion provided on the abutting portion may be brought into contact with the bucket from the axial direction to determine the position of the bucket in the axial direction.

  Although the humidification apparatus provided with the air purification filter unit 30 and the humidification mechanism 40 was demonstrated in the said embodiment, you may apply this invention to the humidification apparatus which is not provided with the air purification filter unit.

  In the above embodiment, the engagement hole 101c is provided in the revolving frame 100 near the back of the bucket 200, the engagement claw 410 is provided in the holding frame 400, and the engagement hole 101c and the engagement claw 410 are engaged.
