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

[First Embodiment]
FIG. 1 shows a perspective view of a first embodiment of a humidifying device 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 are provided on both side surfaces of the casing 1 (see FIG. 3), and an outlet 6 is provided at the rear of the upper surface of the casing 1.

  Thus, in this humidifier, the inlets 5 and 5 are provided in the side surface of the casing 1, the outlet 6 is provided in the upper surface of the casing 1, and the inlet and outlet are eliminated in 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 purifying filter unit 30 and a disc-shaped humidifying filter 40 as an example of a humidifying member are arranged in this order from the front side.

  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. These are related to the gist of the present invention. Detailed explanation is omitted. Reference numeral 200 denotes a control unit that controls the humidifier.

  As shown in FIGS. 2 and 4, the water tank 10 and the air purification filter unit 30 are substantially rectangular in front view, and substantially overlap most of them in the front-rear direction. Further, the lower portion of the air purification filter unit 30 and the humidifying filter 40 overlap in the front-rear direction. Further, each of the water tank 10, the air purification filter unit 30 and the humidifying filter 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 filter 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 cleaning filter unit 30 needs to be cleaned or replaced once every two to one and a half years. Is required approximately once every two years. That is, among the water tank 10, the air purifying filter unit 30 and the humidifying filter 40, the water tank 10 is most frequently replenished with water, and then the air purifying filter unit 30 is frequently cleaned and replaced, The frequency of cleaning and replacement of the humidifying filter 40 is the lowest. That is, in order of the frequency of maintenance work, the water tank 10, the air purifying filter unit 30, and the humidifying filter 40 are arranged. The order of the water tank 10, the air purifying filter unit 30, and the humidifying filter 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 purifying filter unit 30 and the humidifying filter 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 deodorization filter 34 and the humidification filter 40 are arranged in order from the front side of the casing 1.

  On the other hand, in general, the water tank 10, the pre-filter 31, the ionization unit 32, the dust collection filter 33, the deodorization filter 34, and the humidification filter 40 are arranged in descending 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 collecting 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 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 deodorization filter 34, and the humidification filter 40 are obtained. The water tank 10, the prefilter 31, and the ionization unit 32 are arranged. The order of the dust collection filter 33, the deodorization filter 34, and the humidification filter 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 filter 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 with respect to the humidification filter 40, dust and dust attached to the ionization unit 32 do not include moisture from the humidification filter 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 filter 40, the moisture from the humidifying filter 40 does not fill the adsorption hole of the deodorizing filter 34, and therefore the deodorizing performance. Can be prevented.

  In addition, since the said dust collection filter 33 is a pleated filter with a large surface area, it can reduce ventilation resistance.

  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 prefilter 31 of the air purification 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 toward the prefilter 31 gradually 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 and the deodorizing filter 34, and the humidification filter 40 of the air cleaning 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, the dust collection filter 33, and the like of the air purification filter unit 30 are overlaid on the entire bell mouth 23 of the fan 20, while the humidifying filter 40 is Although it overlaps with the lower part, it does not overlap with 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 filter 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 humidifying passage 52 from the lower part of the deodorizing filter 34 of the air purification filter unit 30 to the humidifying filter 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 filter 40, and flows into the humidification passage 52. Most of the water is passed through the humidifying filter 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 humidifying passage 52 flows into the non-humidifying passage 51 and bypasses the humidifying filter 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.

  Thereby, the turbulent flow due to the collision between the humidified air exiting the humidifying filter 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. .

  This will be described in detail with reference to the schematic views of FIGS. 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. Collision between A1 and the air flow A2 flowing through the humidifying passage 52 can be prevented, and 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 modified example of FIG. 8, the partition plate 58 may extend from the air cleaning filter unit 30 (shown in FIG. 3) to the humidifying filter 40.

  Also by doing so, the partition plate 58 can prevent an air flow bypassing the humidifying filter 40 and sufficiently allow air to pass through the humidifying filter 40 to obtain a large amount of humidification.

  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 is an example of the humidifying filter 40 and the water supply device. It is made to follow the water hanger device 60 of this.

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

  The bucket unit 61 of the watering device 60 is configured to apply water to the humidifying filter 40 so as to apply water toward the upstream side of the air flow of the humidifying filter 40, as schematically shown in FIGS. The inner surface 62 of the bucket portion 61 in the vicinity of the first opening 81 and on the humidifying filter 40 side is inclined so that the upstream side of the airflow 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 supported by the bearing 64 at the upper part of the support leg 63 so as to be 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 66. And 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 filter 40 is not shown, but the outer peripheral surface of the humidifying filter 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 humidifying filter 40 exposed from the swivel frame 65. The amount can be increased.

  Further, a gear 79 is formed on the outer peripheral portion of the annular disc portion 67, and a gear 130 (shown in FIG. 16) connected to the output shaft of a geared motor 74 as an example of the motor shown in FIG. The swivel frame 65 can be driven by the geared motor 74.

  As shown in FIG. 2, the geared motor 74 is arranged on the humidifying filter 40 so as not to overlap the air flow direction so that the geared motor 74 does not interfere with the air flow through the humidifying filter 40. ing.

  As a result, the amount of air passing through the humidifying filter 40 is increased, 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 disc portion 67 of the revolving frame 65, and each bucket portion 61 is provided. A substantially claw-shaped holding portion 75 extending inward in the radial direction from the vicinity of the first opening 81 facing forward in the turning direction is provided. In addition, a second opening 82 is provided in the windward side wall 61a of each bucket portion 61 so as to be bent in a dogleg shape toward the rear in the turning direction from the edge continuous with the holding portion 75. Although not shown in FIG. 10 and FIG. 11, the both end surfaces of the humidifying filter 40 shown in FIGS. While restraining and holding, the outer periphery of the humidifying filter 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 (see FIG. 15).

  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 humidifying filter 40, and the humidifying filter 40. Are rotated together with the revolving frame 65.

  In addition to holding the front surface of the humidifying filter 40, the holding portion 75 also serves as a water guide, and serves to serve as a water guide and to remove water discharged from the first and second openings 81 and 82 of the bucket portion 61. Guide the front face radially inward. Here, the water in the bucket portion 61 is mainly discharged from the second opening 82.

  Therefore, the water discharged from the first and second openings 81 and 82 of the bucket portion 61 is quickly guided radially inward from the front surface of the humidifying filter 40 by the holding portion 75 and quickly goes to a wide range. Over time, the amount of humidification can be increased.

  Further, as shown in FIGS. 10 and 11, the portion 78 of the ring-shaped disc portion 67 located in the rotation direction of the swivel frame 65 of the first opening 81 of the bucket portion 61 has water from the opening 81. It functions as a wall portion that blocks the passage of the air flow without going to the humidifying filter 40.

  The wall portion 78 that is a portion of the annular disk portion 67 does not allow the water discharged from the first opening 81 of the bucket portion 61 to go to the humidifying filter 40, but goes behind the humidifying filter 40 together with the air flow. The water from the first opening 81 is guided to the humidification filter 40.

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

  Further, as shown in FIGS. 2 and 12, the bucket portion 61 of the watering device 60 is provided near the first and second openings 81 and 82 when the humidifying filter 40 is filled with water. The inner surface 62 on the side is inclined so that the upstream side of the air flow (the right side in FIGS. 2 and 12) is downward.

  Thus, when water is applied to the humidifying filter 40 from the first and second openings 81 and 82, the vicinity of the first and second openings 81 and 82 of the bucket portion 61 and the humidifying filter 40 side are provided. Since the inner surface 62 is inclined so that the upstream side of the air flow is downward, the water discharged from the first and second openings 81 and 82 has a velocity component directed to the upstream side of the air flow. Therefore, water is applied to the upstream portion of the humidifying filter 40 in the thickness direction, and the applied water reaches the downstream portion of the humidifying filter 40 in the thickness direction together with the air flow. As a result, water spreads over the entire thickness direction of the humidifying filter 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 filter 40 side is positioned behind the inner surface 62 on the humidifying filter 40 side in the vicinity of the first and second openings 81 and 82 and the inner surface 62. However, the inner surface on the side of the humidifying filter 40 may be a single step composed of the inner surface 62 and its extended surface. Further, on the inner surface 62 and the inner surface 72 of the bucket 61, curved concave surfaces 62a and 72a that are continuous with the wall portion 78 are formed. Thus, the water pumped up by the bucket 61 is smoothly discharged from the first and second openings 81 and 82 from the bucket 61.

  Further, as shown in FIGS. 2 and 11, the width of the first opening 81 of the bucket portion 61 in the thickness direction of the humidifying filter 40 is smaller than the thickness dimension of the humidifying filter 40 and the bucket portion. 61 corresponds to a portion on the upstream side in the thickness direction of the humidifying filter 40 (the humidifying filter 40 is not shown in FIG. 11, but the humidifying filter 40 has an inner flange). It is sandwiched between the part 71 and the holding part 75).

  Therefore, the water discharged from the first and second openings 81 and 82 of the bucket portion 61 is applied to the upstream portion of the air flow in the thickness direction of the humidifying filter 40, while the thickness of the humidifying filter 40 is It is not directly hung on the downstream part of the directional air flow.

  Therefore, not only the upstream portion in the thickness direction of the humidifying filter 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 filter 40 together with the air flow. As a result, the water reaches the entire portion in the thickness direction of the humidifying filter 40, and a large amount of humidification can be obtained.

  In addition, since water is not directly applied to the downstream portion of the humidifying filter 40 in the thickness direction, it is possible to prevent water from flowing from the humidifying filter 40 to the downstream side. Can be prevented.

  As shown in FIG. 2, the watering device 60 does not immerse the humidifying filter 40 in water of a water tray 90 as an example of a water storage unit, while the bucket unit 61 immerses in the water of the pumping unit 92 and pumps the pumping unit 92. The dimensions are set and arranged so that water can be pumped from the water.

  As described above, the humidifying filter 40 is arranged so as not to be immersed in the water in the water tray 90, so that the humidifying filter 40 is not flooded with water from the bucket portion 61 when the swivel frame 65 of the watering device 60 is stopped. Further, the humidification filter 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, on / off control of the humidification function can be performed by turning on / off the turning of the turning frame 65 by the geared motor 74.

  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. 13, 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 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 to the humidifying filter 40 is automatically adjusted according to the rotational speed of the fan 20 so that the humidifying 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. 4, 121 is a high-voltage printed circuit board, 122 is an odor sensor, 123 is a streamer, 124 is a light receiving unit, 96 in FIG. 13 is a hole for attaching an antibacterial case, and 97 is a float mounting hole. Since these are not related to the gist of the present invention, detailed description thereof is omitted.

  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, 5 on the side surface 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 filter 40 and the fan 20 of the arranged 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.

  Thus, in this humidifier, the flow of air sucked from the suction ports 5, 5 of the casing 1, that is, the number of times the air flow path is bent, is roughly the air from the suction ports 5, 5 on the side surface of the casing 1. Since the 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.

  Further, the air sucked from the suction ports 5, 5 of the casing 1 is gradually guided toward the 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. 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 filter 40. The purified air coming out of the lower part of the deodorizing filter 34 flows through the humidifying passage 52 and passes through the humidifying filter 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.

  As described above, 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 filter 40, so that 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.

  The clean air flowing through the humidifying passage 52 is prevented from flowing into the non-humidifying passage 51 by bypassing the humidifying filter 40 from the humidifying passage 52 by the partition plate 50. Most of the air that has flowed into the humidifying passage 52 passes through the humidifying filter 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 humidifying filter 40 from the humidifying passage 52, a large amount of humidification can be obtained.

  14A and 14B are a table and a graph showing the humidification amount test results of the first embodiment and the comparative example.

  In FIG. 14B, P represents the first embodiment, and N represents a comparative example different from the first embodiment only in that the partition plate 50 is removed from the first embodiment.

14A and 14B, the first embodiment P and the comparative example N have the same air volume (mainstream air volume) of the fan 20 of 7.5 m ³ / min, and the comparative example N passes through the humidifying filter 40. whereas the amount of air is 3.21m 3 ^/ min to the air amount passing through the humidifying filter 40 in the first embodiment is increased to 3.50 m 3 ^/ min, also humidification amount in Comparative example N Is 556 cc / h, whereas in this first embodiment, the humidification amount is increased to 597 cc / h.

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

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

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

  On the other hand, as shown in FIGS. 2, 10, 11, and 12, the humidifying filter 40 is filled with water from the first and second openings 81 and 82 of the bucket portion 61 of the watering device 60. In detail, the swivel frame 65 having the bucket portions 61, 61, 61... Is swiveled by the geared motor 74 via the gear 79, and the bucket portions 61, 61, 61. Then, water is pumped up sequentially and the humidifying filter 40 is filled with water.

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

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

  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.

  Accordingly, the bucket unit 61 of the watering device 60 can pump water from the pumping unit 92 and apply it to the humidifying filter 40 so that the pumped water amount increases as the rotational speed (air volume) of the fan 20 increases. 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 applied to the humidifying filter 40 can be automatically adjusted, and the humidifying 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.

  FIG. 15 shows a perspective view of the watering device 60 to which the humidifying filter 40 is attached. As shown in FIG. 15, the disc-shaped humidifying filter 40 is attached to the inner periphery of the annular disc portion 67 of the swivel frame 65 of the watering device 60. Then, the boss 66 at the center of the revolving frame 65 passes through a hole (not shown) provided at the center of the humidifying filter 40, and the shaft 110 provided with the flange 110a for holding the humidifying filter is revolved. The humidifying filter 40 is fixed to the revolving frame 65 through a hole provided in the boss portion 66 of the frame 65.

  FIG. 16 shows a perspective view of the water tray 90 with the water hanger 60 attached thereto. The support leg 63 (watering device 60) attached to the pumping portion 92 side of the water tray 90 has a U-shaped bearing portion 64 at the top. The shaft part 110 penetrated through the boss part 66 of the turning frame 65 is supported by the bearing part 64 of the support leg part 63 so as to be turnable. Here, the gear 130 meshes with the gear 79 on the outer periphery of the turning frame 65, and the output shaft of the geared motor 74 is connected to the gear 130.

  FIG. 17 shows a control block diagram of the humidifier. The control unit 200 includes a microcomputer, an input / output circuit, and the like, and includes detection signals from the dust sensor 114, the odor sensor 122, the temperature sensor 201, the humidity sensor 202, and the rotational position detection unit 203, the light receiving unit 124, and an operation control print. Based on the signal from the board 112, the fan motor 21, the geared motor 74, the display printed board 113, and the like are controlled. The temperature sensor 201 and the humidity sensor 202 detect the temperature and humidity of the air sucked from the suction ports 5 and 5 (shown in FIGS. 1 and 3), respectively. The light receiving unit 124 receives a light control signal from a remote controller (not shown).

  FIG. 18 is a diagram for explaining the control of the humidifying operation based on the room temperature of the control unit 200. As shown in FIG. 18, when the room temperature rises, the humidifying operation is performed when the temperature is 1 ° C. or more and less than 40 ° C. Permits humidification operation when the temperature is lower than 0 ° C and less than 37.5 ° C when the temperature falls. In other conditions, humidification operation is prohibited (see FIGS. 19 and 20).

  FIG. 21 is a diagram for explaining the control of the humidifying operation based on the humidity of the control unit 200, and FIG. 22 shows the humidity zones when the humidity is increasing and when the humidity is decreasing.

  As shown in FIGS. 21 and 22, when the humidity increases, when (target humidity−current humidity) is less than 20%, zone D, and when (target humidity−current humidity) exceeds 10% and is less than 20%. Zone C is zone B when (target humidity-current humidity) exceeds 0% and is 10% or less, and zone A is when (target humidity-current humidity) is 0% or less. On the other hand, when the humidity is decreasing, Zone D when (Target humidity-Current humidity) is less than 23%, Zone C when (Target humidity-Current humidity) is over 13% and less than 23%, (Target humidity-Current humidity) When the humidity is more than 3% and less than 13%, the zone is B. When the target humidity is less than 3%, the zone is A. When the humidity zone is A, the humidifying operation is turned off, and when the humidity zone is B, C, D, the humidifying operation is turned on (see FIG. 23).

  The control unit 200 controls the fan motor 21 and the geared motor 74 of the fan 20 and has been described with reference to FIGS. 18 to 20 based on the temperature detected by the temperature sensor 201 and the humidity detected by the humidity sensor 202. When the temperature condition is satisfied and the humidity condition described with reference to FIGS. 21 to 23 is satisfied, by turning on the humidification operation, the humidification operation control based on the AND condition of the temperature condition and the humidity condition provides good comfort. The resulting humidification operation becomes possible.

  Next, FIG. 24 shows the control of the rotation of the swivel frame 65 of the watering device 60 when the humidifying operation is started. In FIG. 24, the fan operation is turned on / off from the upper side, the humidification mode is turned on / off, the humidification request is turned on / off based on the AND condition of the temperature condition and the humidity condition, and the geared motor 74 for the humidification filter is turned on / off. ing.

  First, when the power of the humidifier is turned on, as shown in FIG. 24, the operation of the fan 20 is turned on. Next, for example, when the humidification mode is turned on by a command from a remote controller, the above temperature condition and humidity condition The humidification operation control based on the AND condition is started. Then, the humidification request is turned on based on the determination result of the AND condition of the temperature condition and the humidity condition. At this time, the geared motor 74 for the humidifying filter does not turn on immediately but starts the humidifying preparation operation after 5 seconds. This is in order to prevent phanting in which the determination result of the AND condition of the temperature condition and the humidity condition changes complicatedly and the geared motor 74 is repeatedly turned on and off. In the humidification operation after the humidification preparation operation, the rotation speed of the fan 20 is set to be equal to or higher than the fan lower limit rotation speed, and the rotation speed of the swivel frame 65 of the watering device 60 is set to be equal to or higher than the rotation frame lower limit rotation speed. Yes.

  Next, when the humidification preparatory operation is started, the geared motor 74 is turned on, the swivel frame 65 of the watering device 60 is rotated approximately 1.5 times, and the geared motor 74 is stopped for 1 minute. Perform humidification operation. In this embodiment, the rotational speed of the fan 20 is set lower than the fan lower limit rotation speed during the humidifying operation, and the average rotation speed of the swivel frame 65 of the watering device 60 is set lower than the rotation frame lower limit rotation speed during the humidifying operation. However, the humidifying preparation operation may be performed only under one of the conditions.

  According to the humidifying device having the above configuration, when the humidifying operation is started, the control unit 200 controls the geared motor 74 to control the rotation of the swivel frame 65 of the watering device 60, so that the humidifying filter 40 is infiltrated with water. When the humidifying operation is started to perform the humidifying preparation operation, it is possible to prevent water splashing due to the humidifying filter 40 repelling water.

  In the first embodiment, in the humidifying preparation operation, the swivel frame 65 of the watering device 60 is stopped for 1 minute after being rotated 1.5 times. However, in the humidifying preparation operation, the rotation amount and stop time of the swivel frame are What is necessary is just to set suitably according to the structure of a water splash apparatus or a humidification filter. Also in this case, since the normal humidification operation is performed after sufficiently humidifying the humidification filter 40 in the humidification preparation operation, it is possible to prevent water splash more reliably.

  Further, the geared motor 74 is controlled by the control unit 200 so that the fold direction of the pleated structure of the humidifying filter 40 is substantially horizontal when the rotation of the swivel frame 65 of the watering device 60 in the humidifying preparation operation is stopped. Thus, when the rotation of the swivel frame 65 stops, water is caught in the fold of the pleated structure of the humidifying filter 40 and it is difficult for the moisture to flow down.

  For example, as shown in FIG. 25, a rotational position detector 203 that fixes a magnet 210 at a predetermined position on the outer peripheral side of the swivel frame 65 of the watering device 60 and detects the magnetism of the magnet 210 on the casing 1 side by a Hall element or the like. Place. At this time, the direction of the fold line 40a of the pleated structure of the humidifying filter 40 is surely substantially horizontal at the rotational position of the revolving frame 65 where the magnet 210 and the rotational position detecting unit 203 face each other. Then, the humidifying filter 40 is attached to the swivel frame 65 so that the direction of the fold of the pleat structure is horizontal in accordance with the stop position of the swivel frame 65 in the humidifying preparation operation. The direction of the fold 40a can be reliably made substantially horizontal.

  26A and 26B show an example in which the humidifying filter is positioned with respect to the swivel frame of the watering device. As shown in FIG. 26A, the humidifying filter 140 has a string parallel to the direction of the fold 140a of the pleat structure. There is a crescent-shaped notch 140b, and a positioning portion 141 having the same shape is provided on the revolving frame 165 side. By aligning the notch 140b of the humidifying filter 140 with the positioning portion 141 of the revolving frame 165 and attaching the humidifying filter 140 to the revolving frame 165, the direction of the fold line 140a of the pleated structure of the humidifying filter 140 relative to the revolving frame 165 is changed. Determined. A magnet 210 is arranged at a predetermined position on the outer peripheral side of the revolving frame 165 (on a horizontal plane passing through the rotation center of the revolving frame 165 in FIG. 26A).

  In addition, as shown in FIG. 26B, the humidifying filter 240 is provided with a rectangular hole 240 b in the center, and the longitudinal direction of the rectangular hole 240 b is parallel to the direction of the fold 240 a of the pleated structure of the humidifying filter 240. It is trying to become. And the boss | hub part 266 provided in the rotation center of the turning frame 265 has the substantially same cross-sectional shape as the rectangular hole 240b. The boss portion 266 of the revolving frame 165 is inserted through the rectangular hole 240b of the humidifying filter 240, and the humidifying filter 240 is attached to the revolving frame 265. The direction of the crease 240a is determined. The magnet 210 is arranged at a predetermined position on the outer peripheral side of the revolving frame 265 (on a horizontal plane passing through the rotation center of the revolving frame 265 in FIG. 26B).

  Thus, by positioning and attaching the humidifying filters 140 and 240 to the swivel frames 165 and 265, the direction of the folds 140a and 240a of the pleated structure of the humidifying filters 140 and 240 is surely substantially omitted when the rotation is stopped in the humidifying preparation operation. Can be horizontal.

  The control unit 200 controls the geared motor 74 to rotate the swivel frame 65 of the watering device 60 at a lower speed than the normal humidifying operation at the time of starting the humidifying operation, thereby rotating at a low speed. Since the normal humidification operation is performed after water is sufficiently soaked in the humidifying filter 40 attached to the frame 65, water splash can be prevented more reliably. In this case, as in the first embodiment, only the low-speed rotation may be performed for a predetermined time as the humidifying preparation operation without stopping for one minute after the revolving frame 65 of the watering device 60 is rotated 1.5 times.

  In addition, the control unit 200 controls the geared motor 74 to alternately rotate and stop by rotating and stopping the swivel frame 65 of the watering device 60 for a preset time when the humidifying operation is started. Since normal humidification operation is performed after water has been sufficiently and sufficiently soaked in the humidifying filter 40 attached to the swivel frame 65, water splash can be prevented more reliably.

  The control unit 200 may stop the fan 20 during the humidifying preparation operation. In this case, it is possible to prevent water droplets before being soaked into the humidifying filter 40 from being blown off by the air flow from the fan 20.

[Second Embodiment]
FIG. 27 shows a perspective view of an air conditioner using the humidifying device of the second embodiment of the present invention.

  In this air conditioner, as shown in FIG. 27, a fan 302, a dehumidifying unit 303, a humidifying unit 304 as an example of a humidifying device, an air purifying unit 305, and a control unit 300 are housed in a casing 301. .

  The fan 302 is located on the opposite side of the casing 301 from the air cleaning unit 305, and the air cleaning unit 305, the dehumidifying unit 303, the humidifying unit 304, and the fan 302 are arranged in this order from the air cleaning unit 305 side. When the fan 302 is operating, air is sucked from the suction ports 305a, 305b, and 305c on the air purifying unit 305 side, passes through the dehumidifying unit 303, then passes through the humidifying unit 304, and reaches the fan 302. A is formed. Air from the fan 302 blows out from an outlet 301 c provided on the upper surface of the casing 301. The control unit 300 is disposed on the upper portion of the casing 301 and controls the air cleaning unit 305, the dehumidifying unit 303, the humidifying unit 304, and the fan 302.

  As shown in FIG. 27, the water storage container 390 as an example of a water storage part opens the drawer-type 1st door 301a, and takes it out from the outlet 312 of the casing 301 with the water hanger 360 as an example of a water supply apparatus. Further, a disc-shaped humidifying filter 340 as an example of a humidifying member opens the rotary second door 301 b and takes out from the outlet 313 of the casing 301.

  FIG. 28 shows a perspective view of the humidifying unit 304 of the air conditioner. As shown in FIG. 28, the humidifying unit 304 includes a water storage container 390, a humidifying filter 340, a watering device 360, a geared motor 343 as an example of a watering device motor and a humidifying member motor, and outputs of the geared motor 343. It has a drive gear 431 that meshes with a gear 343a connected to the shaft. The drive gear 431 meshes with a first gear 351 provided on the outer periphery of the revolving frame 350. The water storage container 390 is a water source of moisture given to the air passing through the air flow path A, and is detachably accommodated in the casing 301 (shown in FIG. 27).

  The humidification filter 340 is formed of a non-woven fabric into a disk shape and is attached to the revolving frame 350. The water supplied from the water storage container 390 evaporates while the humidifying filter 340 rotates together with the revolving frame 350. Since the humidifying filter 340 is disposed above the water level when the water storage container 390 is full, it is not in direct contact with the water in the water storage container 390.

  FIG. 29 shows a perspective view of the humidifying unit viewed from the downstream side of the air flow of FIG. As shown in FIG. 29, the water hose device 360 is rotatably supported by the water storage container 390, pumps up the water in the water storage container 390 and discharges it toward the humidification filter 340. In order to reduce the dimension of the humidifying unit 304 in the thickness direction, the humidifying filter 340 and the watering device 360 are opposed to each other in close proximity to each other with their rotation axes in parallel. In the vicinity of the outer periphery of the side surface of the watering device 360, a plurality of bucket portions 421a having trapezoidal openings are provided.

  The second gear 423 fixed coaxially with the watering device 360 meshes with the first gear 351 provided on the outer periphery of the swivel frame 350. The driving force of the geared motor 343 is transmitted to the revolving frame 350 via the gear 343a, the drive gear 431, and the first gear 351, and the humidifying filter 340 rotates together with the revolving frame 350. Then, when the rotation of the humidifying filter 340 is transmitted to the second gear 423 of the watering device 360, the watering device 360 rotates in the direction opposite to the humidifying filter 340. Accordingly, the plurality of bucket portions 421a of the watering device 360 sequentially pumps the water in the water storage container 390 and applies the water toward the upstream side of the air flow of the humidifying filter 340.

  As shown in FIGS. 28 and 29, the humidifying filter 340 attached to the revolving frame 350 is formed in a shape that does not project the rotating shaft in order to facilitate removal from the casing 301. Therefore, the humidification filter 340 is supported by the first gear 351 meshing with the drive gear 431 and the second gear 423. In order to maintain the revolving frame 350 in a stable posture, the drive gear 431 and the second gear 423 are positioned below the rotation axis of the first gear 351 and are relative to the vertical center line of the humidifying filter 340. They are located on opposite sides. For this reason, the humidification filter 340 attached to the revolving frame 350 rotates stably even if it is not axially supported.

  In the air conditioner having the above configuration, the heating operation mode and the heating / humidifying operation mode can be executed. In the heating operation mode, the heat source unit (not shown) of the dehumidifying unit 303 in which the dehumidifying capacity is stopped is operated to perform heating. In the humidifying operation mode, the heat source unit of the dehumidifying unit 303 and the humidifying unit 304 are operated simultaneously.

  Further, in the air conditioner, during the heating and humidifying operation, the air flow formed by the fan 302 passes through the heat exchange unit of the dehumidifying unit 303 whose dehumidifying capacity is stopped and flows to the humidifying unit 304. And since this air is heated by the heat exchange part of the dehumidification unit 303 and enters the humidification unit 304 in a state where the relative humidity is lowered, a lot of moisture is humidified. Moreover, since the air which passes the dehumidification unit 303 is heated by the heat exchange part, the temperature rise width of air is low and it is suitable for small-scale heating.

  Further, in the air conditioner, in the dehumidifying operation mode, the humidifying capacity of the humidifying unit 304 is stopped, and moisture in the air is adsorbed by the dehumidifying unit 303.

  According to the air conditioner configured as described above, when the humidifying operation is started, the control unit 300 controls the geared motor 343, and the humidifying filter 340 rotated by the geared motor 343 is supplied with water from the watering device 360, whereby the humidifying filter. It is possible to prevent water splashing due to the humidifying filter 340 repelling water at the time of starting the humidifying operation in which the humidifying preparation operation in which water is immersed in 340 is performed.

  Moreover, in the air conditioner of this 2nd Embodiment, it has the same effect as the humidifier of 1st Embodiment by applying the same structure as the humidifier of 1st Embodiment, or performing control.

  In the humidifying device used in the air conditioner of the second embodiment, the geared motor 343 also serves as a driving device that rotates the humidifying filter 340 that is a humidifying member and a driving unit of the watering device 360 that is a water supply device. However, the water supply device may be driven by a driving means different from the driving device for the humidifying member.

  In the second embodiment, the first gear 351 is provided on the outer periphery of the revolving frame 350. However, a belt pulley may be provided instead of the gear, and the revolving frame may be belt-driven, or A motor shaft may be connected to the center of the revolving frame, and the revolving frame may be directly driven by the motor.

  Moreover, in the said 1st 2nd Embodiment, although the humidification apparatus using the water hanger 60,360 which has the bucket parts 61 and 421a as a water supply apparatus was demonstrated, a water supply apparatus is not restricted to this, For example, a pump etc. It may be used to supply water from the water storage unit to the humidifying member.
