Description

  The present invention relates to a humidifier.

  Conventionally, as a humidifier, the thing of Unexamined-Japanese-Patent No. 2005-282980 (patent document 1) is known.

  This humidifier is provided with a fan, a humidifying member, and a watering device for pouring water on the humidifying member in a casing having a suction port and an outlet.

  This watering device is composed of a plurality of ladles that rotate along a vertical plane, and this ladle is provided with a bucket portion at the tip of a rod that rotates along the vertical plane. This bucket portion has an opening for pumping and discharging in front of the rotation direction. Further, the inner surface of the bucket portion on the rod side is perpendicular to the rod and faces the tangential direction of the circular orbit of the bucket portion.

  Then, the conventional humidifying device starts applying the pumped water from the opening to the humidifying member after the bucket portion is located near the top, and after having entered the descending process, finishes applying the entire amount of water to the humidifying member. ing.

  Therefore, in the conventional humidifying device, even if water is applied to the humidifying member from the opening of the bucket portion as the rod rotates, the entire amount of the pumped water cannot be applied near the top, that is, the bucket Only after the portion passed the top and entered the descending stroke, the entire amount of water could be discharged from the bucket portion, and water could only be sufficiently applied to one side past the top of the humidifying member.

Therefore, the conventional humidifier has a problem that the amount of humidification is small because water cannot be spread over a wide range of the humidifying member.
Japanese Patent Laying-Open No. 2005-282980, FIG.

  Therefore, the problem of the present invention is that even if the bucket part does not enter the descending process considerably, the entire amount of water can be discharged near the top, and the water can be spread over a wide range of the humidifying member. The object is to provide a humidifier with a large amount.

In order to solve the above problems, the humidifying device of the present invention provides:
A casing having an inlet and an outlet;
A fan disposed in the casing;
A humidifying member for humidifying the air flow generated by the fan;
A water tray disposed below the humidifying member;
A bucket unit for pumping water from the water tray is provided on the swivel frame, and a watering device for pouring water on the humidifying member from the opening in the swirl direction front of the bucket unit;
A motor for turning the turning frame of the watering device,
The bucket portion of the watering device is characterized in that the pumped water starts to be applied to the humidifying member before reaching the top, and the entire amount of the pumped water is discharged near the top.

  According to the humidifying device of the present invention, the bucket portion of the watering device starts to apply the pumped water to the humidifying member before reaching the top, and discharges the entire amount of the pumped water near the top. Water can be spread over a wide range on both sides of the top of the top, and the amount of humidification can be increased.

In one embodiment,
The inner surface on the humidifying member side of the bucket portion with respect to the locus of the edge of the opening of the bucket portion of the watering device on the humidifying member side and passing through the edge of the opening on the humidifying member side Is inclined at an acute angle toward the anti-humidifying member.

  In the embodiment, the humidifying member of the bucket portion is a tangential plane of the locus of the edge on the humidifying member side of the opening of the bucket portion of the watering device and a tangential plane passing through the edge on the humidifying member side. Since the inner surface on the side is inclined at an acute angle toward the anti-humidifying member, the inner surface on the humidifying member side of the bucket portion becomes horizontal before the bucket goes to the top. Therefore, the bucket part begins to discharge water before going to the top, and finishes discharging all the water near the top.

  In this way, before the bucket part goes to the top, it starts to discharge water and finishes discharging all the water in the vicinity of the top, so that the water is spread over a wide range of humidifying members on both sides of the top. Can increase the amount of humidification.

In one embodiment,
The humidifying member is a humidifying rotor,
The humidification rotor is attached to a swivel frame of the watering device.

  According to the above embodiment, before the bucket part reaches the top of the humidification rotor, the pumped water starts to be applied to the humidification rotor, and the water applied to the humidification rotor moves forward in the rotation direction together with the humidification rotor. In combination with this, water can be spread over a wide range on both sides of the top of the humidification rotor, and the amount of humidification can be increased.

  According to this invention, the bucket portion of the watering device starts to apply the pumped water to the humidifying member before reaching the top, and discharges the entire amount of the pumped water near the top, so the humidifying members on both sides of the top It is possible to spread water over a wide range, and to increase the amount of humidification.

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

  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 and 5 are provided on both side surfaces of the casing 1 (see FIG. 3), and a blower outlet 6 is provided at the rear of the upper surface of the casing 1.

  Thus, in this humidifier, the suction ports 5 and 5 are provided on the side surface of the casing 1, the air outlet 6 is provided on the upper surface of the casing 1, and the air inlet and the air outlet are eliminated on the rear surface 7 of the casing 1. Therefore, the rear surface 7 of the casing 1 of the humidifier can be brought into close contact with the wall surface of a room (not shown), and the degree of freedom of installation of the humidifier is increased.

  Since the conventional humidifier has a suction port on the rear surface of the casing, the suction resistance increases unless a gap of a certain size is provided between the casing and the wall surface of the room. It was not possible, and the degree of freedom of installation was low.

  On the other hand, as shown in FIG. 2, in the casing 1, a water tank 10 is erected on the front side, and a fan 20 driven by a fan motor 21 is arranged on the rear side. The water tank 10 has the same well-known structure as the oil tank of the oil stove. A check valve (not shown) is provided at the bottom outlet, and the check valve is pushed while the water tank 10 is erected. To be released. Between the water tank 10 and the fan 20, an air purification filter unit 30 and a humidification rotor 40 as an example of a humidification member are arranged in this order from the front side.

  As shown in FIGS. 2 and 4, the water tank 10 and the air purification filter unit 30 are generally rectangular in front view, and substantially overlap most of the front and rear directions. Further, the lower portion of the air purification filter unit 30 and the humidification rotor 40 overlap in the front-rear direction. Further, each of the water tank 10, the air purification filter unit 30 and the humidifying rotor 40 is disposed so as to overlap at least a part of the bell mouth 23 of the fan 20, that is, covers at least a part of the bell mouth 23. The noise from the fan 20 is reduced.

  In the present specification, the bell mouth 23 is a concept including an opening surrounded by the bell mouth 23 in addition to the bell mouth 23 itself.

  In general, the water tank 10, the air purification filter unit 30, and the humidification rotor 40 are arranged in descending order of maintenance frequency. For example, the water tank 10 must be replenished with water almost every day, and the air purification filter unit 30 needs to be cleaned or replaced once every two weeks to one and a half years. Is required approximately once every two years. That is, among the water tank 10, the air purification filter unit 30 and the humidification rotor 40, the water tank 10 is most frequently replenished with water, and then the air purification filter unit 30 is frequently cleaned and replaced, The frequency of cleaning and replacement of the humidification rotor 40 is the lowest. That is, when the maintenance work is performed in the order of frequency, the water tank 10, the air purification filter unit 30, and the humidification rotor 40 are arranged. The order of the water tank 10, the air purification filter unit 30, and the humidification rotor 40 is the casing. It is also the order close to the front side of 1, that is, the front panel 3.

  As described above, the higher the maintenance frequency, the closer to the front side of the casing 1, that is, the front panel 3. Therefore, the maintenance workability of the water tank 10, the air purification filter unit 30, and the humidification rotor 40 is improved. It is getting better.

  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. Therefore, the water tank 10, the pre-filter 31, the ionization unit 32, the dust collection filter 33, the deodorizing filter 34, and the humidification rotor 40 are arranged in order from the front side of the casing 1.

  On the other hand, in general, the water tank 10, the prefilter 31, the ionization unit 32, the dust collection filter 33, the deodorizing filter 34, and the humidification rotor 40 are arranged in the order of maintenance frequency. For example, the water tank 10 must be replenished with water almost every day, the frequency of cleaning the prefilter 31 is about once every two weeks, and the frequency of maintenance of the ionization unit 32 is about half a year. The frequency of cleaning or replacement of the dust collection filter 33 is about once a year, and the frequency of cleaning the deodorizing filter 34 is about once a year and a half. Replacement is required about once every two years. Arranged in order of frequency of maintenance work, the water tank 10, the prefilter 31, the ionization unit 32, the dust collection filter 33, the deodorizing filter 34, and the humidification rotor 40 are formed. The water tank 10, the prefilter 31, and the ionization unit 32 are arranged. The order of the dust collection filter 33, the deodorizing filter 34, and the humidification rotor 40 is also the order close to the front side of the casing 1, that is, the front panel 3.

  Thus, the higher the maintenance frequency, the closer to the front side of the casing 1, that is, the front panel 3, the water tank 10, the prefilter 31, the ionization unit 32, the dust collecting filter 33, the deodorizing filter. The maintenance workability of each of the 34 and the humidifying rotor 40 is improved because the lower maintenance work frequency does not interfere with the higher maintenance work frequency.

  Further, since the ionization unit 32 is arranged on the upstream side of the air flow from the humidification rotor 40, the dust and dust attached to the ionization unit 32 do not include moisture from the humidification rotor 40. The discharge failure can be prevented.

  Further, since the deodorizing filter 34 is disposed on the upstream side of the air flow with respect to the humidifying rotor 40, the moisture from the humidifying rotor 40 does not fill the adsorption hole of the deodorizing filter 34, and therefore the deodorizing performance. Can be prevented.

  The dust collection filter 33 is a pleated filter having a large surface area due to the presence of pleats, so that the ventilation resistance can be reduced.

  On the other hand, the rear surface 11 of the water tank 10 is also used as a guide surface for guiding the air sucked from the suction ports 5 and 5 as shown in FIG. The size of is reduced.

  Specifically, as shown in FIG. 3, the water tank 10 has a substantially trapezoidal horizontal cross section, and the rear surface 11 is inclined on both sides so that the thickness gradually increases from the side to the center. It consists of surfaces 12 and 12 and a central flat surface 13.

  The inclined surfaces 12 and 12 of the rear surface 11 of the water tank 10 gradually guide the air sucked from the suction ports 5 and 5 of the casing 1 toward the pre-filter 31 of the air cleaning filter unit 30 to reduce the ventilation resistance. To do.

  However, instead of the inclined surfaces 12 and 12, a curved surface (not shown) that guides the air from the suction port 5 gradually toward the prefilter 31 may be used.

  Further, the central portion having the flat surface 13 of the water tank 10 is made thicker than the side portions, and the portion that becomes the central dead space is effectively used for the central portion of the water tank 10 to increase the tank capacity. ing.

  On the other hand, the pre-filter 31, the ionization unit 32, the dust collection filter 33, the deodorizing filter 34, and the humidification rotor 40 of the air purification filter unit 30 are partially overlapped in the front-rear direction and arranged in a substantially straight line, The airflow sucked from the suction port 5 is reduced in the number of bendings to reduce the ventilation resistance.

  On the other hand, as shown in FIGS. 2 and 4, the deodorizing filter 34 and the dust collection filter 33 of the air purification filter unit 30 are overlaid on the entire bell mouth 23 of the fan 20, while the humidification rotor 40 is below the bell mouth 23. Although it overlaps with the side part, it does not overlap with the upper part of the bellmouth 23. Therefore, the air flowing through the non-humidifying passage 51 from the upper portion of the deodorizing filter 34 to the upper portion of the bell mouth 23 does not pass through the humidifying rotor 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 cleaning filter unit 30 to the humidification rotor 40 and the upper part of the deodorizing filter 34 to the upper part of the bell mouth 23 of the fan 20 are not. The humidifying passage 51 is partitioned by a partition plate 50.

  The 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 rotor 40, and flows into the humidification passage 52. Most of the air flows through the humidification rotor 40 so that a large amount of humidification can be obtained.

  If this partition plate 50 is not present, the air flow A3 flowing through the humidification passage 52 flows into the non-humidification passage 51 and bypasses the humidification rotor 40, as in the comparative example shown in the schematic diagram of FIG. The amount of humidification is reduced.

  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.

  This prevents turbulent flow due to the collision between the humidified air exiting the humidifying rotor 40 and the non-humidified air flowing through the non-humidified passage 51, thereby reducing ventilation resistance and reducing noise. .

  6 and 7, the non-humidification passage 51 and the humidification passage 52 are separated by the partition plate 50 extending to the vicinity of the fan 20, so that the air flow A <b> 1 flowing through the non-humidification passage 51. Can be prevented from colliding with the air flow A2 flowing through the humidifying passage 52. Therefore, turbulent flow due to the collision can be prevented, ventilation resistance can be reduced, and noise can be reduced.

  However, as shown in the modification of FIG. 8, the partition plate 58 may extend from the air purification filter unit 30 to the humidification rotor 40.

  Also by doing so, the partition plate 58 can prevent an air flow that bypasses the humidification rotor 40 and sufficiently allow the air to pass through the humidification rotor 40 to obtain a large humidification amount.

  As shown in FIG. 4, the partition plate 50 includes horizontal portions 53 and 54 and inclined portions 55 that connect the horizontal portions 53 and 54, and substantially follows the humidification rotor 40 and the watering device 60. I am doing so.

  On the other hand, the humidification rotor 40 is made of, for example, a nonwoven fabric or the like, and is a so-called vaporization filter or the like. The humidification rotor 40 allows air to pass therethrough and humidifies the vaporized air. As shown in FIGS. 2 to 4, the humidification rotor 40 has a disk shape and is fixed to the watering device 60.

  The bucket portion 61 of the watering device 60, as schematically shown in FIGS. 2 and 3, when water is applied to the humidification rotor 40 so as to apply water toward the upstream side of the air flow of the humidification rotor 40, The vicinity of the opening 81 of the bucket portion 61 and the inner surface 62 on the humidifying rotor 40 side are inclined so that the upstream side of the air flow is downward.

  As shown in FIG. 9, the watering device 60 includes a support leg portion 63, a swivel frame 65, and bucket portions 61, 61,. A turning frame 65 is attached to the support leg 63 so as to be turnable along a vertical plane. More specifically, the boss 66 at the center of the revolving frame 65 is attached to the upper part of the support leg 63 via a horizontal shaft 64 so as to be freely rotatable.

  As shown in FIG. 10, the revolving frame 65 includes a boss portion 66, an annular disc portion 67, and a plurality of radial arm portions 68, 68,... That connect the annular disc portion 67 and the boss portion. Have The arm portions 68, 68,... Are connected by a ring portion 69 for reinforcement.

  As shown in FIGS. 10 and 11, a plurality of bucket portions 61, 61,... Are provided at equal intervals on the circumference on one end surface of the annular disc portion 67 of the revolving frame 65. 10 and 11, the humidifying rotor 40 is not shown, but the outer peripheral surface of the humidifying rotor 40 is exposed from the revolving frame 65 between the bucket portion 61 and the bucket portion 61.

  Thereby, between the bucket part 61 and the bucket part 61, the water discharged from the bucket part 61 can be infiltrated from the outer peripheral surface of the humidification rotor 40 exposed from the revolving frame 65, and the humidification is performed. The amount can be increased.

  Further, a gear 79 is formed on the outer peripheral portion of the ring-shaped disc portion 67, and a gear of a geared motor 74 as an example of the motor shown in FIG. 2 is engaged with the gear 79, and the turning frame 65 is driven by the geared motor 74. I can do it.

  As shown in FIG. 2, the geared motor 74 is disposed on the humidification rotor 40 so as not to overlap the airflow direction so that the geared motor 74 does not interfere with the airflow through the humidification rotor 40. ing.

  As a result, the amount of air passing through the humidification rotor 40 increases, and the amount of humidification can be increased.

  Further, as shown in detail in FIGS. 10 and 11, inner flange portions 71, 71,... Are intermittently provided on the inner peripheral side of the annular disk portion 67 of the revolving frame 65, and A substantially claw-shaped holding portion 75 extending inward in the radial direction from the vicinity of the opening 81 facing forward in the turning direction is provided. .. And the holding portions 75, 75,... Of the ring-shaped disc portion 67 restrain both end surfaces of the humidification rotor 40 shown in FIGS. 2 and 3 by the inner flange portions 71, 71,. The outer periphery of the humidifying rotor 40 is held by the inner peripheral surface 76 of the annular disc portion 67 and the inner peripheral surface 77 of the bucket portion 61.

  Further, each of the arm portions 68, 68,... Of the revolving frame 65 is provided with a linear rib portion 89. Although not shown, the rib portion 89 is caused to bite into the humidification rotor 40, and the humidification rotor 40 is provided. Are rotated together with the revolving frame 65.

  In addition to holding the front surface of the humidifying rotor 40, the holding portion 75 also serves as a water guide, and guides the water discharged from the opening 81 of the bucket portion 61 to the inner side in the radial direction of the front surface of the humidifying rotor 40. .

  Therefore, the water discharged from the opening 81 of the bucket portion 61 is quickly guided radially inward from the front surface of the humidification rotor 40 by the holding portion 75, and quickly reaches a wide range, thereby increasing the amount of humidification.

  Further, as shown in FIGS. 10 and 11, the portion 78 of the annular disc portion 67 located in the rotation direction of the swivel frame 65 of the opening 81 of the bucket portion 61 causes water from the opening 81 to enter the humidifying rotor 40. It functions as a wall that blocks you from going behind the air flow without going.

  The wall portion 78 which is a part of the annular disk portion 67 prevents water discharged from the opening 81 of the bucket portion 61 from going to the humidifying rotor 40 and not to go behind the humidifying rotor 40 together with the air flow. Then, the water from the opening 81 is guided to the humidification rotor 40.

  Therefore, this wall part 78 can prevent water splashing to the rear of the humidification rotor 40, increase the amount of humidification, and can prevent water jumping from the fan 20 and the blower outlet 6.

  As shown in FIGS. 2 and 12, the bucket portion 61 of the watering device 60 is located near the opening 81 and the inner surface 62 on the humidifying rotor 40 side is upstream of the air flow when water is applied to the humidifying rotor 40. Inclined so that the side is down.

  Thus, when water is applied to the humidifying rotor 40 from the opening 81, the inner surface 62 of the bucket portion 61 and the inner surface 62 on the humidifying rotor 40 side is inclined so that the upstream side of the airflow is downward. Therefore, the water discharged from the opening 81 has a velocity component directed toward the upstream side of the air flow. Therefore, water is applied to the upstream portion of the humidification rotor 40 in the thickness direction, and the applied water reaches the downstream portion of the humidification rotor 40 in the thickness direction together with the air flow. As a result, water spreads over the entire thickness direction of the humidification rotor 40, and a large amount of humidification can be obtained.

  In the embodiment shown in FIG. 12, the inner surface of the bucket 61 on the humidifying rotor 40 side is a two-stage of an inner surface 62 on the humidifying rotor 40 side in the vicinity of the opening 81 and an inner surface 72 located deeper than the inner surface 62. However, the inner surface on the humidifying rotor 40 side may be a single step composed of the inner surface 62 and its extended surface.

  Further, as shown in FIGS. 2 and 11, the width of the opening 81 of the bucket portion 61 in the thickness direction of the humidifying rotor 40 is smaller than the thickness dimension of the humidifying rotor 40 and the opening 81 of the bucket portion 61. Corresponds to the upstream portion of the humidifying rotor 40 in the thickness direction (the humidifying rotor 40 is not shown in FIG. 11), but the humidifying rotor 40 includes an inner flange portion 71, a holding portion 75, and the like. Between them.)

  Therefore, the water discharged from the opening 81 of the bucket portion 61 is applied to the upstream side portion of the air flow in the thickness direction of the humidification rotor 40, while the downstream side of the air flow in the thickness direction of the humidification rotor 40. It cannot be hung directly on the part.

  Therefore, not only the upstream portion in the thickness direction of the humidifying rotor 40 to which water has been applied is distributed, but also the water that has been applied to the downstream side in the thickness direction of the humidifying rotor 40 together with the air flow. As a result, water reaches the entire portion in the thickness direction of the humidification rotor 40, and a large amount of humidification can be obtained.

  Further, since water is not directly applied to the downstream portion of the humidifying rotor 40 in the thickness direction, water splashing from the humidifying rotor 40 to the downstream side can be prevented, and consequently, water splashing from the fan 20 and the air outlet 6 can be prevented. Can be prevented.

  On the other hand, FIG. 13 is a schematic diagram showing a state in which the bucket portion 61 is cut in a direction perpendicular to the rotation center axis of the humidification rotor 40 in order to explain the inclination of the inner surface 62 of the bucket portion 61 on the humidification rotor 40 side. is there.

  As can be seen from FIGS. 12 and 13, a three-dimensional display conical surface (circle in the two-dimensional display) C that is the locus of the edge 62 a of the inner surface 62 on the humidifying rotor 40 side in the vicinity of the opening 81 of the bucket portion 61 of the watering device 60. The inner surface 62 of the bucket portion 61 on the humidifying rotor 40 side is the anti-humidifying rotor with respect to the tangential plane TP passing through the edge 62a of the inner surface 62 on the humidifying rotor 40 side in the vicinity of the opening 81. Inclined at an acute angle θ toward the 40 side.

  Thus, since the inner surface 62 on the humidifying rotor 40 side in the vicinity of the opening 81 of the bucket portion 61 is inclined by the acute angle θ with respect to the tangential plane TP, as is apparent from FIG. The opening 81 has a central angle θ (equal to the acute angle θ) with respect to the direction of the apex S around the rotation center O before the edge 62a of the inner surface 62 of the opening 81 reaches the apex S of the locus circle C in the two-dimensional display. The inner surface 62 on the humidifying rotor 40 side in the vicinity becomes horizontal.

  Therefore, as shown in FIGS. 13 and 14, the bucket portion 61 starts discharging water before going to the top S of the locus circle C, and finishes discharging all the water near the top RS of the humidifying rotor 40.

  Thus, the bucket 61 starts to discharge water at an angle larger than the central angle θ before going above the top RS of the humidification rotor 40, and discharges the entire amount of water near the top RS of the humidification rotor 40. In combination with the fact that the water applied to the humidification rotor 40 moves forward in the rotation direction R together with the humidification rotor 40 as indicated by the arrow W in FIG. 14, both sides of the top RS of the humidification rotor 40 are combined. It is possible to spread water over a wide range, and to increase the amount of humidification.

  The optimum value of the acute angle θ varies depending on the rotational speed of the revolving frame 65 and the size of the humidifying rotor 40, but is preferably about 5 to 30 degrees, for example.

  On the other hand, as shown in FIG. 2, the watering device 60 does not allow the humidifying rotor 40 to be immersed in the water in the water tray 90, while the bucket unit 61 is immersed in the water in the pumping unit 92 and pumps water from the pumping unit 92. The dimensions are set and arranged so that

  Thus, the humidification rotor 40 is arranged so as not to be immersed in the water in the water tray 90, so that the humidification rotor 40 is not splashed with water from the bucket portion 61 when the swivel frame 65 of the watering device 60 is stopped. In addition, the humidification rotor 40 is not soaked in the water of the water tray 90 and does not absorb water, so that the humidification function is turned off.

  Therefore, by turning on and off the turning of the turning frame 65 by the guard motor 74, the humidification function can be turned on and off.

  On the other hand, as shown in FIG. 2, the water tray 90 is provided with a partition wall 91 having an inverted L-shaped cross section, and is divided into a pumping portion 92 and a non-pumping portion 93. The bucket unit 61 pumps water from the pumping unit 92. The non-pumping portion 93 receives the air pressure on the upstream side of the air cleaning filter unit 30.

  The upper part of the partition wall 91 is in close contact with the lower part of the pre-filter 31, the ionization unit 32, the dust collection filter 33 and the deodorizing filter 34 of the air purification filter unit 30, and the resistance loss of air passing through the air purification filter unit 30. Thus, a differential pressure is generated between the air pressure on the non-pumping portion 93 and the air pressure on the pumping portion 92.

  The non-pumping section 93 is provided with a float switch 94, and when the water level of the non-pumping section 93 is lower than the steady state by a certain value, a display or alarm indicating that there is no water in the water tank 10 is not shown. Or the alarm section.

  As shown in more detail in FIG. 15, the water tray 90 divides a wide pumping unit 92 from which water is pumped by the bucket unit 61 and a non-pumping unit 93 that receives the air pressure upstream of the air purification filter unit 30. A partition wall 91 (only a part is shown) is provided, and a long long hole 95 is provided in the lower part of the partition wall 91 as a water passage hole.

  As a result, when the differential pressure between the upstream side and the downstream side of the air purification filter unit 30 increases as the rotational speed of the fan 20 increases, the water level of the pumping section 92 depends on the magnitude of this differential pressure. The water level is higher than the water level of the non-pumping portion 93, and the pumping water amount of the bucket portion 61 can be automatically adjusted according to the rotational speed of the fan 20.

  Therefore, the amount of watering with respect to the humidification rotor 40 is automatically adjusted according to the rotational speed of the fan 20 so that the humidification amount can be easily and automatically adjusted.

  The horizontally long slot 95 provided in the partition wall 91 of the water tray 90 is not easily exposed to air even when the water level is low, and quickly supplies water from the non-pumping section 93 to the pumping section 92. The response speed of the automatic adjustment of the water level of the pumping unit 92 is increased.

  On the other hand, the non-pumping portion 93 is provided with a water tank setting portion 98 for setting the water tank 10, and the height of the bottom surface 98 b of the water tank setting portion 98 is near the partition wall 91 of the non-pumping portion 93. It is higher than the height of the bottom surface 93b. Further, a notch 101 is provided on the peripheral wall of the water tank installation part 98 from the upper end.

  As a result, the rotation of the fan 20 is stopped, the differential pressure between the upstream side and the downstream side of the air purification filter unit 30 disappears, the water returns from the pumping unit 92 to the non-pumping unit 93, and the non-pumping unit 93 When the water level exceeds a certain value, water is discharged from the non-pumping portion 93 to the buffer water storage portion 99 through the notch 101 to prevent water from overflowing from the non-pumping portion 93 to the outside. .

  Instead of the notch 101, a through hole may be provided in the upper part of the peripheral wall of the water tank installation part 98.

  In FIG. 2, 111 is a power printed circuit board, 112 is an operation control printed circuit board, 113 is a display printed circuit board, 114 is a dust sensor, and 115 is a spare filter. In FIG. A substrate, 122 is an odor sensor, 123 is a streamer, 124 is a light receiving unit, and in FIG. 15, 96 is a hole for mounting an antibacterial agent case, 97 is a float mounting hole, and these are the gist of the present invention Detailed explanation is omitted because it is not relevant.

  The humidifier configured as described above operates as follows.

  As shown in FIGS. 2 and 3, when the fan 20 is driven by the fan motor 21 and the swivel frame 65 of the watering device 60 is driven by the geared motor 74, air is sucked from the suction ports 5 and 5 of the side surface 3 of the casing 1. Inhaled. This sucked air changes the direction of the flow 90 degrees once from the rear surface 11 of the water tank 10 and the prefilter 31 of the air purifying filter unit 30 toward the prefilter 31, and then becomes substantially straight. The pre-filter 31, the ionization unit 32, the dust collection filter 33, the deodorizing filter 34, the humidification rotor 40 and the fan 20 of the arrayed air purification filter unit 30 flow in a substantially straight line in the horizontal direction to be cleaned and humidified. Then, when it leaves the fan 20, the flow direction is changed 90 degrees once in a substantially vertical direction, and the air is discharged from the air outlet 6 on the upper surface of the casing 1.

  As described above, in this humidifier, the flow of the air sucked from the suction ports 5 and 5 of the casing 1, that is, the number of times of bending of the air flow path is approximately from the suction ports 5 and 5 of the side surface 3 of the casing 1. Since the air cleaning filter unit 30 is once for the pre-filter 31 and once for exiting the fan 20, the air flow resistance is small because the number of times the air flow path is bent is small.

  Air sucked from the suction ports 5 and 5 of the casing 1 is gradually guided toward the prefilter 31 of the air purification filter unit 30 by the inclined surfaces 12 and 12 on both sides of the rear surface 11 of the water tank 10. The draft resistance is small because there is little sudden change of direction.

  The clean air coming out from the upper part of the deodorizing filter 34 of the air purification filter unit 30 flows through the non-humidification passage 51 partitioned from the humidification passage 52 by the partition plate 50, and does not pass through the humidification rotor 40. The clean air coming out from the lower part of the deodorizing filter 34 flows through the humidifying passage 52, passes through the humidifying rotor 40 and is humidified while being sucked into the fan 20 through the upper part of the mouse 23. Then, the air is sucked into the fan 20 through the lower part of the bell mouth 23.

  Thus, since the air flowing through the non-humidifying passage 51 from the upper portion of the deodorizing filter 34 to the upper portion of the bell mouth 23 does not pass through the humidifying rotor 40, the ventilation resistance of the air flowing through the non-humidifying passage 51 is reduced. Can be reduced. In particular, when the geared motor 74 is stopped, the operation of the watering device 60 is stopped, the humidification operation is not performed, and only the air cleaning operation is performed, the presence of the non-humidification passage 51 allows a sufficient air volume. (Air volume) can be secured.

  Also, the clean air flowing through the humidifying passage 52 is prevented from flowing into the non-humidifying passage 51 from the humidifying passage 52 by bypassing the humidifying passage 52 by the partition plate 50, and therefore the lower portion of the deodorizing filter 34. Most of the air that has flowed into the humidification passage 52 passes through the humidification rotor 40. Thus, since the partition plate 50 extending from the deodorizing filter 34 to the vicinity of the fan 20 prevents the air flow bypassing the humidification rotor 40 from the humidification passage 52, a large humidification amount can be obtained.

  (A) and (B) of FIG. 16 are a table and a graph which show the humidification amount test result of this embodiment and a comparative example.

  In FIG. 16, P represents this embodiment, and N represents a comparative example different from this embodiment only in that the partition plate 50 is removed from this embodiment.

  As can be seen from FIGS. 16A and 16B, the air volume (main flow rate) of the fan 20 is the same as that of the embodiment P and the comparative example N at 7.5 m 3 / min. In the comparative example N, the humidifying rotor 40 is used. In this embodiment, the amount of air passing through the humidification rotor 40 is increased to 3.50 m3 / min, and in the comparative example N, the amount of humidification is 556 cc. In this embodiment, the amount of humidification increased to 597 cc / h.

  The ratio of the increase in the humidification amount with respect to the comparative example N of the embodiment P is (597−556) /556=0.074.

  That is, in this embodiment P, the amount of humidification increased by about 7% compared with the comparative example N.

  Further, the partition plate 50 extending from the deodorizing filter 34 of the air purifying filter unit 30 to the vicinity of the fan 20 causes collision between the humidified air exiting the humidifying rotor 40 and the non-humidified air flowing through the non-humidified passage 51. This prevents turbulence from occurring. As a result, ventilation resistance can be reduced and noise can be reduced.

  On the other hand, the humidifying rotor 40 shown in FIG. 2 receives water from the opening 81 of the bucket portion 61 of the watering device 60. Specifically, as shown in FIGS. 2, 10, 11, and 12, the swivel frame 65 having bucket portions 61, 61, 61... , 61, 61... Sequentially pump water from the pumping section 92 of the water tray 90 and pour the humidifying rotor 40 with water.

  When water is applied from the bucket portion 61 to the humidification rotor 40, as shown in FIGS. 2 and 12, the inner surface 62 near the opening 81 of the bucket portion 61 and the humidification rotor 40 side is located on the upstream side of the air flow. Therefore, the water discharged from the opening 81 has a velocity component directed to the upstream side of the air flow. Therefore, water is applied to the upstream portion of the humidifying rotor 40 in the thickness direction, and the applied water also reaches the downstream portion of the humidifying rotor 40 in the thickness direction together with the air flow. And water spreads over the whole thickness direction of the humidification rotor 40, and a big humidification amount can be obtained.

  Further, as shown in FIGS. 2 and 11, the width of the opening 81 of the bucket portion 61 in the thickness direction of the humidifying rotor 40 is smaller than the thickness dimension of the humidifying rotor 40 and the opening 81 of the bucket portion 61. Corresponds to the upstream portion of the humidifying rotor 40 in the thickness direction, so that water discharged from the opening 81 of the bucket portion 61 is exposed between the bucket portion 61 and the bucket portion 61. It is applied only to the upstream portion of the air flow in the thickness direction of the outer peripheral surface of the humidifying rotor 40.

  Therefore, the water soaks into the humidifying rotor 40 from the outer peripheral surface of the upstream portion in the thickness direction of the humidifying rotor 40 on which the water has been poured, and the water soaked into the upstream portion is humidified together with the air flow. The water reaches the downstream portion of the rotor 40 in the thickness direction and eventually reaches the entire thickness direction of the humidification rotor 40, so that a large amount of humidification can be obtained.

  Further, since water is not directly applied to the downstream portion of the humidifying rotor 40 in the thickness direction, water splashing from the humidifying rotor 40 to the downstream side can be prevented, and consequently, water splashing from the fan 20 and the air outlet 6 can be prevented. Can be prevented.

  Furthermore, as shown in FIGS. 12 and 13, the tangential plane TP with respect to the conical surface C which is a three-dimensional locus of the edge 62 a of the inner surface 62 on the humidifying rotor 40 side in the vicinity of the opening 81 of the bucket portion 61 of the watering device 60. In addition, the inner surface 62 of the bucket portion 61 on the humidifying rotor 40 side has an acute angle to the anti-humidifying rotor 40 side with respect to a tangential plane TP passing through the edge 62a of the inner surface 62 on the humidifying rotor 40 side near the opening 81. Since it is inclined at θ, the edge 62a of the inner surface 62 in the vicinity of the opening 81 of the bucket portion 61 is vertical before it reaches the top S of the locus circle C in the sectional display, as is apparent from the schematic sectional view of FIG. At the central angle θ from the shaft (equal to the acute angle θ), the inner surface 62 on the humidifying rotor 40 side in the vicinity of the opening 81 becomes horizontal, and then the inner surface 62 is inclined with respect to the horizontal plane as the revolving frame 65 rotates. Xu Continue to increase to.

  Therefore, as shown in FIGS. 13 and 14, the bucket portion 61 starts to discharge water before going to the top S of the locus circle C, and finishes discharging the entire amount of water near the top RS of the humidification rotor 40.

  Therefore, from the bucket portion 61, starting to discharge water at an angle larger than the central angle θ before going to the top RS of the humidification rotor 40, and finishing discharging the entire amount of water in the vicinity of the top RS of the humidification rotor 40, In combination with the fact that the water applied to the humidifying rotor 40 moves forward in the rotational direction R together with the humidifying rotor 40 as indicated by the arrow W in FIG. 14, it is in a wide range on both sides of the top RS of the humidifying rotor 40. Water can be spread and the amount of humidification can be increased.

  Furthermore, the water discharged from the opening 81 of the bucket portion 61 is quickly guided radially inward from the front surface of the humidification rotor 40 by the holding portion 75 shown in FIGS. Go fast.

  Therefore, the humidifying amount can be increased also by the holding portion 75.

  The holding portion 75 has a function as a water guide for increasing the humidification amount in addition to the function of holding the humidification rotor 40.

  Further, as shown in FIGS. 10 and 11, the water discharged from the opening 81 of the bucket portion 61 is caused by a wall portion 78 that is a portion of the ring-shaped disc portion 67 of the swivel frame 65 located in front of the opening 81. The air flow is blocked behind the humidifying rotor 40 and falls toward the humidifying rotor 40.

  Therefore, the wall portion 78 can prevent water splashing to the rear of the humidification rotor 40, increase the amount of humidification, and can prevent water splashing from the fan 20 and the blower outlet 6.

  In this embodiment, when water is applied to the humidification rotor 40 from the opening 81 of the bucket portion 61, the inner surface 62 on the humidification rotor 40 side in the vicinity of the opening 81 of the bucket portion 61 is on the upstream side of the air flow. Due to the inclined configuration, the applied water has a velocity component toward the upstream side of the air flow, and the opening 81 of the bucket portion 61 is upstream of the humidifying rotor 40 in the thickness direction. The water from the opening 81 is applied to the upstream portion of the humidifying rotor 40 in the thickness direction, and the inner surface of the bucket portion 61 near the opening 81 on the humidifying rotor 40 side. The inner surface 62 is at an acute angle θ toward the anti-humidification rotor 40 with respect to the tangential plane TP with respect to the conical surface C that is the locus of the edge 62a of the 62 and the tangent plane TP passing through the edge 62a of the inner surface 62. By the configuration of being inclined, the bucket unit 61 starts to discharge water before going to the top RS of the humidification rotor 40, and finishes discharging all the water near the top RS of the humidification rotor 40, and the bucket unit With the configuration of the holding portion 75 provided in the vicinity of the opening 81 of 61, the water discharged from the opening 81 is quickly guided radially inward of the front surface of the humidifying rotor 40, and the front of the opening of the bucket portion 61 is By the configuration of the wall portion 78 of the swivel frame 65 located at the position, the water discharged from the opening 81 of the bucket portion 61 is prevented from going rearward from the humidification rotor 40 together with the air flow, and dropped toward the humidification rotor 40. A very large amount of humidification can be obtained by a synergistic action.

  On the other hand, as shown in FIG. 2, the bypass of air to the air purification filter unit 30 is blocked by a partition wall 91. Due to the resistance loss of the air passing through the pre-filter 31, ionization unit 32, dust collection filter 33 and deodorizing filter 34 of the air purification filter unit 30, a pressure difference is generated between the upstream side and the downstream side of the air purification filter unit 30. This pressure difference becomes higher in accordance with the rotation speed of the fan 20, that is, the increase in the air volume.

  The pressure on the upstream side of the air purification filter unit 30 and the partition wall 91 is substantially atmospheric pressure, and this substantially atmospheric pressure acts on the water of the non-pumping portion 93 of the water tray 90, while the air purification filter unit 30 and the partition are separated. The pressure on the downstream side of the wall 91 is a low pressure lower than the atmospheric pressure by the resistance loss, and this low pressure acts on the water in the pumping portion 92 of the water tray 90. There is the above-described pressure difference between the substantially atmospheric pressure acting on the water of the non-pumping portion 93 of the water tray 90 and the low pressure acting on the water of the pumping portion 92.

  On the other hand, the non-pumping portion 93 and the pumping portion 92 of the water tray 90 communicate with each other through a long hole 95 at the bottom of the partition wall 91, so that the water level of the pumping portion 92 of the water tray 90 is set to the non-pumping portion 93. The above-described pressure difference is higher than the water level. This pressure difference becomes higher in accordance with the rotation speed of the fan 20, that is, the increase in the air volume.

  Therefore, the water level of the pumping unit 92 becomes higher according to the rotational speed of the fan 20, that is, the increase in the air volume.

  Therefore, the bucket unit 61 of the watering device 60 can pump water from the pumping unit 92 so as to increase the pumped water amount in accordance with the increase in the rotational speed (air volume) of the fan 20 and hang it on the humidifying rotor 40. it can.

  Thus, since the water level of the pumping unit 92 is automatically adjusted according to the rotational speed of the fan 20, the air volume (air volume) can be obtained without controlling the rotational speed of the swivel frame 65 of the watering device 60. Accordingly, the amount of water splashing on the humidification rotor 40 can be automatically adjusted, and the humidification amount can be easily adjusted automatically.

  The automatic adjustment of the water level of the pumping section 92 is performed by supplying water to the pumping section 92 through the long hole 95 at the lower part of the partition wall 91, and therefore can be performed quickly and with good responsiveness. In particular, since the long elongate hole 95 that is difficult to be exposed to the air is used, water can be supplied quickly through the elongate hole 95, and the water level of the pumping portion 92 can be automatically adjusted with good responsiveness.

  Next, when the rotation of the fan 20 stops, the differential pressure between the upstream side and the downstream side of the air purification filter unit 30 disappears, so that water returns from the pumping unit 92 having a high water level to the non-pumping unit 93 having a low water level. Thus, the water level of the non-pumping portion 93 may become a certain value or more.

  In this case, since water is discharged from the non-pumping portion 93 to the buffer water storage portion 99 through the notch 101, the water does not overflow from the non-pumping portion 93 to the outside.

  Next, maintenance workability will be described.

  Generally, when arranged in the order of maintenance frequency, the water tank 10, the pre-filter 31, the ionization unit 32, the dust collection filter 33, the deodorizing filter 34, and the humidification rotor 40 become the front side of the casing 1, that is, the order close to the front panel 3. become. For example, the water tank 10 must be replenished with water almost every day, the frequency of cleaning the prefilter 31 is about once every two weeks, and the frequency of maintenance of the ionization unit 32 is about half a year. The frequency of cleaning or replacement of the dust collection filter 33 is about once a year, and the frequency of cleaning the deodorizing filter 34 is about once a year and a half. Replacement is required about once every two years.

  When water is supplied to the water tank 10, the front panel 3 is removed from the casing body 2, the water tank 10 is taken out from the casing body 2, and water is supplied to the water tank 10.

  At this time, since the air purification filter unit 30 and the humidification rotor 40 are on the rear surface side of the water tank 10, they do not interfere with the water supply operation to the water tank 10.

  Therefore, the maintenance workability of the water tank 10 is good.

  Next, when the prefilter 31 is cleaned, the front panel 3 is detached from the casing body 2 and the water tank 10 is taken out, and then the prefilter 31 is taken out and cleaned.

  At this time, since the ionization part 32, the dust collection filter 33, the deodorizing filter 34, and the humidification rotor 40 are in the rear surface side of the pre filter 31, it is not necessary to remove and take out.

  Thus, the cleaning of the pre-filter 31 is easy because the water tank 10 in front of the pre-filter 31 may be removed.

  Thus, the higher the maintenance frequency, the closer to the front side of the casing 1, that is, the front panel 3, the water tank 10, the prefilter 31, the ionization unit 32, the dust collecting filter 33, the deodorizing filter. The maintenance workability of each of the 34 and the humidifying rotor 40 is good because a lower maintenance work frequency does not interfere with a higher maintenance work frequency.

  In the humidifier of the above embodiment, the suction port 5 is provided on the side surface of the casing 1, the air outlet 6 is provided on the upper surface of the casing 1, and the air inlet and the air outlet are eliminated on the rear surface 7 of the casing 1. The rear surface of 1 can be brought into close contact with the wall surface of the room, and there is an advantage that the degree of freedom of installation is high.

  Further, in the humidifier of the above embodiment, the air sucked from the suction ports 5 and 5 on the side surface 3 of the casing 1 flows between the rear surface 11 of the water tank 10 and the prefilter 31 of the air cleaning filter unit 30. The direction of the flow is changed once by 90 degrees toward the filter 31, and then the pre-filter 31, the ionization unit 32, the dust collection filter 33, the deodorizing filter 34, and the humidification rotor 40 of the air purifying filter unit 30 arranged in a substantially straight line. From the fan 20 to the fan 20 in a straight line in the horizontal direction, cleaned and humidified, and then, when exiting the fan 20, the direction of the flow is changed 90 degrees once in the vertical direction. Since the air outlet 6 is discharged from the upper surface, the number of times the air flow path is bent is approximately from the suction ports 5 and 5 of the side surface 3 of the casing 1 to the air purification filter unit 30. A total of 2 times once and once, when leaving the fan 20 to Refiruta 31, because a small number of bends in the air flow path has the advantage that the ventilation resistance is small.

  In the humidifier of the above embodiment, the air sucked from the suction ports 5, 5 of the casing 1 is pre-filter 31 of the air purification filter unit 30 by the inclined surfaces 12, 12 on both sides of the rear surface 11 of the water tank 10. Since there is little sudden direction change, there is an advantage that the ventilation resistance is small.

  Moreover, in the humidifier of the said embodiment, since the inclined surfaces 12 and 12 of the rear surface 11 of the water tank 10 are combined with a guide surface, an independent guide member is unnecessary, Therefore, the dimension of the front-back direction of a humidifier is made. Can be small.

  Moreover, in the humidification apparatus of the said embodiment, since the center part which has the flat surface 13 of the water tank 10 is thicker than the side part which has the inclined surfaces 12 and 12, the location used as a center dead space is effective. This can be used to increase the tank capacity.

  In the humidifying device of the above embodiment, since the ionization unit 32 is arranged on the upstream side of the air flow from the humidification rotor 40, the dust and dust attached to the ionization unit 32 include moisture from the humidification rotor 40. Therefore, defective discharge can be prevented.

  Moreover, in the humidification apparatus of the said embodiment, since the deodorizing filter 34 is arrange | positioned in the upstream of an air flow rather than the humidification rotor 40, the water | moisture content from the humidification rotor 40 will fill the adsorption hole of the deodorizing filter 34. FIG. Therefore, it is possible to prevent a decrease in deodorizing performance.

  Moreover, in the humidification apparatus of the said embodiment, since there exists pleat as the dust collection filter 33, since the pleat filter with a large surface area is used, ventilation resistance can be reduced.

  In the humidifying device of the above embodiment, the humidifying rotor 40 overlaps a part of the bell mouth 23, and each of the air cleaning filter unit 30 and the water tank 10 overlaps all of the bell mouth 23. Since the bell mouth 23 is covered with the filter unit 30 and the water tank 10, noise can be reduced.

  Further, in the humidifier of the above embodiment, the partition plate 50 prevents clean air from bypassing the humidification rotor 40 from the humidification passage 52 and flowing into the non-humidification passage 51, so that the deodorizing filter 34 enters the humidification passage 52. Since most of the air that has flowed in passes through the humidification rotor 40, a large amount of humidification can be obtained.

  Moreover, in the humidifier of the said embodiment, since the partition plate 50 extended from the deodorizing filter 34 of the air purifying filter unit 30 to the fan 20 or the vicinity of the bell mouth 23 is provided, the humidified air which came out of the humidification rotor 40, and The collision with the non-humidified air flowing through the non-humidified passage 51 can be prevented, the generation of turbulent flow can be prevented, the ventilation resistance can be reduced, and the noise can be reduced.

  In the humidifying device of the above embodiment, the humidifying rotor 40 overlaps a part of the bell mouth 23 of the fan 20, and the humidifying rotor 40 does not overlap the other part of the bell mouth 23 of the fan 20. Since a part of the filter unit 30 is overlapped, the ventilation resistance can be reduced. In particular, when only the air cleaning operation is performed without performing the humidification operation, a sufficient air volume (air amount) can be secured.

  In the humidifying device of the above embodiment, when water is poured from the bucket portion 61 to the humidifying rotor 40, the inner surface 62 near the opening 81 of the bucket portion 61 and the humidifying rotor 40 side is on the upstream side of the air flow. Therefore, the water discharged from the opening 81 has a velocity component facing the upstream side of the air flow, and water is applied to the upstream side portion of the humidifying rotor 40 in the thickness direction. Thus, the applied water reaches the downstream portion in the thickness direction of the humidification rotor 40 together with the air flow, and eventually the water reaches the entire thickness direction of the humidification rotor 40, resulting in a large humidification amount. Can be obtained.

  Further, in the humidifying device of the above embodiment, the opening 81 of the bucket portion 61 corresponds to the upstream portion of the humidifying rotor 40 in the thickness direction, and the water discharged from the opening 81 of the bucket portion 61 is humidified. Since it is applied to the upstream portion of the air flow in the thickness direction of the outer peripheral surface of the rotor 40, the water that has soaked into the upstream portion in the thickness direction of the humidifying rotor 40 along with the air flow in the thickness direction of the humidifying rotor 40 As a result, water reaches the entire downstream portion of the humidifying rotor 40 in the thickness direction, and a large amount of humidification can be obtained.

  Further, in the humidifying device of the above embodiment, water is not directly applied to the downstream portion of the humidifying rotor 40 in the thickness direction, so that water splashing from the humidifying rotor 40 to the downstream side can be prevented. Water splash from the outlet 6 can be prevented.

  Moreover, in the humidifier of the said embodiment, it is tangent plane TP with respect to the conical surface C which is the locus | trajectory of the edge 62a of the inner surface 62 at the side of the humidification rotor 40 near the opening 81 of the bucket part 61 of the watering device 60, and the above-mentioned The inner surface 62 on the humidifying rotor 40 side in the vicinity of the opening 81 of the bucket portion 61 is inclined at an acute angle θ toward the anti-humidifying rotor 40 side with respect to the tangential plane TP passing through the edge 62a of the inner surface 62 on the humidifying rotor 40 side in the vicinity of the opening 81. Therefore, the fact that all of the water is completely discharged near the top RS of the humidification rotor 40 and the water applied to the humidification rotor 40 moves forward in the rotational direction R together with the humidification rotor 40 are combined. Water can be spread over a wide range on both sides of the top RS of the humidification rotor 40, and the amount of humidification can be increased.

  Further, in the humidifying device of the above embodiment, the revolving frame 65 is provided with a holding portion that is located in the vicinity of the opening 81 of the bucket portion 61 and holds the humidifying rotor 40 and functions as a water guide. The amount of humidification can be increased by quickly guiding the water from the opening 81 to the inside in the radial direction of the humidification rotor 40 and quickly spreading it over a wide range of the humidification rotor 40.

  Further, in the humidifying device of the above embodiment, the water discharged from the opening 81 of the bucket portion 61 goes to the rear of the humidifying rotor 40 together with the air flow, so that the wall portion 78 of the swivel frame 65 positioned in front of the opening 81. Therefore, it is possible to prevent water splashing to the rear of the humidification rotor 40, to increase the amount of humidification, and to prevent water splashing from the fan 20 and the blower outlet 6.

  In the humidifying device of the above embodiment, when water is applied to the humidifying rotor 40 from the opening 81 of the bucket portion 61, the inner surface 62 on the humidifying rotor 40 side in the vicinity of the opening 81 of the bucket portion 61 is on the upstream side of the air flow. The inclined water has a velocity component toward the upstream side of the air flow, and the opening 81 of the bucket portion 61 is in the thickness direction of the humidifying rotor 40. The water from the opening 81 is applied to the upstream portion in the thickness direction of the humidifying rotor 40, and the humidifying rotor 40 side in the vicinity of the opening 81 of the bucket portion 61 is configured to correspond to the upstream portion. The inner surface 62 has an acute angle toward the anti-humidification rotor 40 with respect to the tangential plane TP with respect to the conical surface C that is the locus of the edge 62a of the inner surface 62 of the inner surface 62. The bucket portion 61 starts to discharge water before going to the top RS of the humidification rotor 40, and finishes discharging the entire amount of water near the top RS of the humidification rotor 40. By the configuration of the holding portion 75 provided in the vicinity of the opening 81 of the portion 61, the water discharged from the opening 81 is quickly guided radially inward of the front surface of the humidifying rotor 40, and the opening of the bucket portion 61 is By the configuration of the wall portion 78 of the swivel frame 65 located in the front, the water discharged from the opening 81 of the bucket portion 61 is blocked from going backward from the humidifying rotor 40 together with the air flow, and falls toward the humidifying rotor 40. Due to the synergistic effect of the treatment, a very large amount of humidification can be obtained.

  In the humidifying device of the above embodiment, since the outer peripheral surface of the humidifying rotor 40 is exposed from the revolving frame 65 between the bucket portion 61 and the bucket portion 61, the humidification is started from the exposed outer peripheral surface of the humidifying rotor 40. The amount of humidification can be increased by immersing water in the rotor 40.

  In the humidifying device of the above embodiment, the gear 79 is provided on the outer periphery of the revolving frame 65, and the geared motor 74 that drives the gear 79 is arranged so as not to overlap the humidifying rotor 40 in the air flow direction. The geared motor 74 does not interfere with the air flow through the humidifying rotor 40, and the amount of air passing through the humidifying rotor 40 can be increased, so that the amount of humidification can be increased.

  Further, in the humidifying device of the above embodiment, the humidifying rotor 40 is arranged so as not to be immersed in the water in the pumping portion 92 of the water tray 90, so turning of the turning frame 65 is turned on and off by the geared motor 74. Thus, the humidifying function can be turned on / off.

  Further, in the humidifying device of the above embodiment, the partition wall 91 causes the water tray 90 to be pumped up by the bucket unit 61 and the non-pumping unit 93 that receives the air pressure upstream of the air cleaning filter unit 30. Since a long hole 95 as a water passage hole is provided in the lower part of the partition wall 91, the differential pressure between the upstream side and the downstream side of the air purification filter unit 30 according to the increase in the air volume of the fan 20 As the air pressure becomes higher, the water level of the pumping portion 92 becomes higher according to the height of the differential pressure, and even if the rotational speed of the swivel frame 65 is not changed, The amount of pumped water can be automatically adjusted, the amount of water applied to the humidification rotor 40 can be automatically adjusted, and the amount of humidification can be easily adjusted automatically.

  Further, in the humidifying device of the above embodiment, since the long long hole 95 is provided in the lower part of the partition wall 91 of the water tray 90, the long long hole 95 is not easily exposed to the air. Water can be quickly supplied from the pumping unit 93 to the pumping unit 92, and the response speed of the automatic adjustment of the water level of the pumping unit 92 can be increased.

Since the rotor 40 is arranged, the maintenance workability of each of the water tank 10, the prefilter 31, the ionization unit 32, the dust collection filter 33, the deodorizing filter 34, and the humidification rotor 40 is less frequent. However, the maintenance workability is good because it does not interfere with the maintenance work with a higher frequency.

  Moreover, in the humidification apparatus of the said embodiment, since the fan 20 is located in the back side rather than the water tank 10, the air purifying filter unit 30, and the humidification rotor 40, the fan 20 is the water tank 10, the air purifying filter unit. Therefore, the maintenance work such as cleaning and replacement of the 30 and the humidification rotor 40 is not obstructed, and therefore the workability of the maintenance is good.

  In the said embodiment, although the blower outlet 6 was provided in the upper surface of the casing 1, you may provide a blower outlet in the side surface of a casing, or you may provide in both the upper surface and side surface of a casing.

  Moreover, in the said embodiment, although the air purifying filter unit 30 contained the pre filter 31, the ionization part 32, the dust collection filter 33, and the deodorizing filter 34, in addition to these, you may contain the disinfection filter, Or you may remove the ionization part 32, the deodorizing filter 34, etc. FIG. For example, the air purifying filter unit may include only a pre-filter and a dust collection filter, or may include only a single filter. Alternatively, the air purification filter unit 30 may be removed.

  Moreover, in the said embodiment, although the partition plate 50 was provided, you may remove this partition plate.

  Moreover, in the said embodiment, although the humidification rotor 40 was used as a humidification member, it replaced with this, using the stationary humidification member separate from a watering apparatus, and in the upstream part of this stationary humidification member, You may make it pour water from the bucket part provided in the turning frame of a watering apparatus.

  Moreover, in the said embodiment, when water is applied to the humidification rotor 40 from the opening 81 of the bucket part 61, the inner surface 62 by the side of the humidification rotor 40 near the opening 81 of this bucket part 61 is on the upstream side of the air flow. However, only one of the configurations is provided. Or may not be provided with both configurations. Further, the holding portion 75 and the wall portion 78 may also be removed.

  In the above embodiment, the gear 79 is provided on the outer periphery of the revolving frame 65. However, instead of the gear, a belt pulley may be provided to drive the revolving frame as a belt, or at the center of the revolving frame. The shaft of the motor may be connected and the revolving frame may be directly driven by the motor.

  Further, in the above embodiment, the partition wall 91 is provided in the water tray 90 to partition the pumping portion 92 and the non-pumping portion 93, and the elongated hole 95 is provided as a water passage hole in the lower portion of the partition wall 91.
