  The problem in the above-mentioned conventional example is that it is difficult to adjust the air volume of the two air paths to different air volumes because the air path resistance of the two air paths is greatly different by two motors with one electric motor. there were.

  That is, in the conventional product, a motor of both shafts is used, two different types of blades are provided on both shafts, and two types of casings are provided so as to cover the two types of blades, but the number of parts is large. As a result, the mold cost was high and the product cost was high.

  Therefore, an electric motor is disposed in the casing, one vane is provided on the rotating shaft of the electric motor, and vane portions composed of a plurality of blades are provided on both sides of the main plate of the vane. The air volume of each was adjusted. However, when rotating blades of the same blade diameter with the same number of rotations by an electric motor, if the difference in airway resistance between the two airways is large, the airflow type and static pressure type blades are adjusted only by the height of the blades. In addition to being difficult, the height of the blades is high. As a result, the height of the casing also increased, and as a result, the size of the product increased.

  Therefore, the present invention has an object to facilitate adjustment of the respective air volumes even when the air is blown to two air paths by one electric motor and the air path resistances of the two air paths are greatly different.

  In order to achieve this object, the present invention includes a main body case having an intake port and an exhaust port, and a heat pump provided in the main body case, and the heat pump is sequentially provided downstream of the compressor and the compressor. A first air blower that is formed by a provided radiator, an expansion unit, and a heat sink, and that blows air sucked into the main body case from the intake port to the exhaust port through the radiator; and the intake air A second blower for blowing the air sucked into the main body case from the opening to the exhaust outlet through the heat radiator and the heat absorber in turn, and is arranged between the heat radiator and the heat absorber; A dehumidification rotor is movably provided, and the dehumidification rotor includes a moisture release portion and a moisture absorption portion. The moisture release portion is provided in an air passage between the radiator and the heat absorber, and the moisture absorption portion includes the heat absorber and the moisture absorber. Install in the air path between the exhaust vents The heating means is provided between the radiator and the moisture releasing section, and the first air blowing means and the second air blowing means are provided in one electric motor disposed in the casing and a rotating shaft of the electric motor. The blade is provided with a first blade portion corresponding to the first air blowing means and a second blade portion corresponding to the second air blowing means on both sides of the main plate. The outer diameter of the first blade portion is smaller than the diameter of the second blade portion, and the height of the first blade portion is higher than the height of the second blade portion, thereby achieving the initial purpose. To do.

  As described above, the present invention includes a main body case having an intake port and an exhaust port, and a heat pump provided in the main body case. The heat pump includes a compressor and a radiator sequentially provided downstream of the compressor. A first blower unit that is formed by an expansion unit and a heat absorber, and blows air sucked into the main body case from the intake port to the exhaust port through the radiator, and the main unit from the intake port A second air blowing means for blowing the air sucked into the case to the exhaust port through the heat radiator and the heat absorber in order is provided, and dehumidification is freely performed between the heat radiator and the heat absorber. A rotor is provided, and the dehumidifying rotor is composed of a moisture releasing portion and a moisture absorbing portion, the moisture releasing portion is provided in an air passage between the radiator and the heat absorber, and the moisture absorbing portion is provided between the heat absorber and the exhaust port. Provided in the air path of the radiator and the moisture release The first air blowing means and the second air blowing means have one electric motor disposed in the casing, and one blade fixed to the rotating shaft of the electric motor. The blade is provided with a first blade portion corresponding to the first air blowing means and a second blade portion corresponding to the second air blowing means on both sides of the main plate, and the outer diameter of the first blade portion. Is smaller than the diameter of the second blade part, and the height of the first blade part is higher than the height of the second blade part, and the air is blown to two air paths by one electric motor. Even in the case where the airflow resistances are greatly different, the respective air volume adjustments can be easily performed.

  That is, of the two air paths, the first air path requires a larger air volume than the second air path, but the air path resistance is small, and the second air path has a smaller air volume than the first air path. However, when the air passage resistance is a large air passage, the first blade portion has a smaller blade diameter and a higher blade portion height than the second blade portion, and the second blade portion is the first blade portion. The blade diameter is made larger than that of the blade portion and the height of the blade portion is lowered.

  In this way, since two types of blade diameters and heights of the blade portions are provided on both sides of the main plate, when the first blade portion and the second blade portion are rotated by the electric motor at the same rotational speed, Compared with the second blade part, the first blade part has a higher air volume but less static pressure, and the second blade part has a lower air volume than the first blade part but has a lower static pressure. It becomes a feather that can be taken. That is, the first blade portion is an air flow type blade, and the second blade portion is a static pressure blade.

  In conclusion, it is possible to easily adjust to the airflow type and static pressure type blades without increasing the height of the blade portion.

  According to these results, even when the air path resistances of the two air paths are greatly different, the respective air volume adjustments can be easily performed.

  In addition, this eliminates the resistance imbalance between the first blade portion and the second blade portion, so that the motor speed is improved and noise can be reduced by achieving an optimum rotation speed.

  Hereinafter, the present embodiment will be described with reference to the accompanying drawings.

(Embodiment 1)
As shown in FIGS. 1 to 11, the dehumidifying device of the present embodiment includes a main body case 3 having an intake port 1 and an exhaust port 2, and a heat pump 4 provided in the main body case 3. The heat pump 4 is formed by a compressor 5, a radiator 6, expansion means 7, and a heat absorber 8.

  The air blown into the main body case 3 from the air inlet 1 is blown to the exhaust port 2 through the radiator 6 by the first air blowing means 9, and the air from the air inlet 1 to the main body by the second air blowing means 9. The air sucked into the case 3 is blown to the exhaust port 2 through the radiator 6 and the heat absorber 8 in order. Thus, the air blown to the exhaust port 2 by the first blower unit 9 and the second blower unit 9 is mixed at the exhaust port 2 and exhausted into the room.

  A dehumidification rotor 10 is rotatably provided between the radiator 6 and the heat absorber 8 in the air path of the second air blowing means 9, and the dehumidification rotor 10 includes a moisture release unit 11, a moisture absorption unit 12, It has.

  The moisture releasing part 11 is provided in the air path between the radiator 6 and the heat absorber 8, and the moisture absorbing part 12 is provided in the air path between the heat absorber 8 and the exhaust port 2. A heater as the heating means 13 is provided between them.

  That is, the air sucked into the main body case 3 from the air inlet 1 by the second air blowing means 9 is further heated by the heater after being heated by the radiator 6, and becomes high temperature and low relative humidity air. The air is sent to the moisture release unit 11. Further, the air blown to the moisture release unit 11 takes in the moisture of the moisture release unit 11 and is sent to the heat absorber 8 in a high humidity state. The heat absorber 8 is condensed to dehumidify and reaches the moisture absorbing portion 12. Therefore, the moisture releasing part 11 of the dehumidifying rotor 10 in the dry state is rotated by the driving means 14 to become the moisture absorbing part 12, and the moisture not dehumidified by the heat absorber 8 is absorbed by the moisture absorbing part 12 and dehumidified.

  The first air blowing means 9 and the second air blowing means 9 are formed by one electric motor 16 disposed in the casing 15 and one blade fixed to the rotating shaft of the electric motor 16. That is, the blade includes a first blade portion 17 corresponding to the first air blowing means 9 and a second blade portion 18 corresponding to the second air blowing means 9 on both sides of the main plate 19.

  A feature of this embodiment is the shape of the blade. That is, the blade includes a first blade portion 17 corresponding to the first air blowing means 9 and a second blade portion 18 corresponding to the second air blowing means 9 on both sides of the main plate 19. The shape of the part 17 and the 2nd blade | wing part 18 differs. That is, the outer diameter of the blade portion is that the first blade portion is smaller than the second blade portion, and the height is higher in the first blade portion 17 than in the second blade portion 18.

  Specifically, the blades are a first blade portion 17 corresponding to the first air blowing means 9 on one outer peripheral side surface of the disk-shaped main plate 19 and a second blade portion 18 corresponding to the second air blowing means 9 on the other surface. And a boss portion to which the rotating shaft of the electric motor 16 is inserted and fixed in the central portion of the main plate 19 is integrally formed.

  Further, the first blade portion 17 is formed from a plurality of first blades 20 having a curved surface shape, and a notch portion 22 is provided at the tip of the first blade 20. The second blade portion 18 is also formed from a plurality of second blades 21 having a curved surface shape, and a notch portion 22 is provided at the tip of the second blade 21.

  That is, the outer diameter of the first blade 20 is smaller than the outer diameter of the second blade 21, and the height of the first blade 20 is higher than the height of the second blade 21.

  In this way, on both sides of the main plate 19, blade portions having different outer diameters of the two types of blades and the height of the blades are provided. Therefore, when the first blade portion 17 and the second blade portion 18 are rotated by the electric motor 16 at the same rotational speed, the first blade portion 17 is more likely to generate an air volume than the second blade portion 18. Compared to the first blade portion 17, the second blade portion 18 is a blade that is less likely to take static pressure but less static pressure. That is, the first blade portion 17 is an air flow type blade, and the second blade portion 18 is a static pressure type blade.

  As a conclusion, it is possible to easily adjust to the airflow type and static pressure type blades without increasing the height of the blade part, and even when the airflow resistance of the two airways is greatly different, each airflow adjustment is easy. It is possible.

  Further, since the width of the second blade 21 in the second blade portion 18 is larger than the width of the first blade 20 in the first blade portion 17, the second blade portion 18 is connected to the first blade portion 17. Compared to the first blade portion 17, the work amount of the blade portion is increased, and the second blade 21 outer peripheral diameter dimension of the second blade portion 18 and the height dimension of the second blade 21 are not increased. The blade performance can be improved.

  Further, the pitch of the first blades 20 in the first blade portion 17 is the same as the pitch of the second blades 21 in the second blade portion 18, and the second blade is positioned at an intermediate position between the first blades 20. Since the first blade portion 17 and the second blade portion 18 are displaced by a half pitch, the pressure fluctuation between the blades generated during rotation can be offset and smoothly rotated. Therefore, the blade efficiency is improved.

  In addition, there is a difference in the width between the tip portion and the root portion of the blade, the root portion is wider than the tip portion, and the width difference (W2−W1) of the first blade 20 in the first blade portion 17 The width difference (W4-W3) of the second blade 21 in the second blade 18 is larger, and the weight of the blade itself can be reduced by scraping the blade tip that is not working, and the efficiency of the motor 16 However, there is a demerit that the strength of the blade itself decreases if the blade tip is sharpened too much, so the amount to be cut is set in inverse proportion to the blade height (H1, H2). In the case of the first blade 20 in one blade portion 17, the cutting amount of the blade tip portion is approximately 1.7% to 1.9% with respect to the blade height H 1, and the second blade in the second blade portion 18. In the case of 21, the shaving amount at the blade tip is blurred. About 14% to 15% with respect to de height H2 was optimal.

  The first blade 20 in the first blade portion 17 and the second blade 21 in the second blade portion 18 are provided with a notch 22 at the tip, and the curved surface of the suction portion 23 of the casing 15. It is possible to increase the radius of the gas, and the resistance at the suction portion is reduced and a smooth flow can be realized, so that noise can be reduced. In this embodiment, the radius of the curved surface of the suction portion 23 is 9 mm.

  Moreover, the outer peripheral part of the tongue piece part that is a part of the outer peripheral part of the first scroll part and the second scroll part also serves as a part of the air path from the radiator to the moisture releasing part 11 of the dehumidifying rotor 10. The outer peripheral dimensions of the first scroll portion and the second scroll portion of the casing 15 are the same.

  Thus, the outer peripheral dimensions of the first scroll portion of the casing 15 facing the outer periphery of the first blade portion 17 and the second scroll portion of the casing 15 facing the outer periphery of the second blade portion 18 are the same. Therefore, since the air path resistance of the air path from the shared radiator 6 to the moisture releasing part 11 of the dehumidifying rotor 10 is small and an air path with little sudden pressure change can be formed, there is a silent effect.

  The casing 15 is formed of a first scroll portion of the casing 15 facing the outer periphery of the first blade portion 17 and a second scroll portion of the casing 15 facing the outer periphery of the second blade portion 18. A connecting portion between the first scroll portion and the second scroll portion. In the same plane as the main plate 19 of the blade, a partition portion 24 is provided with a predetermined distance from the blade, and a first portion of the partition portion 24 is provided. A substantially semi-circular protrusion 25 is provided on the blade portion side of the.

  In this manner, the partition portion 24 is provided in the casing 15 in the same plane as the main plate 19 of the blade, having a predetermined distance from the blade, and the projection 25 is provided on the first blade portion 17 side of the partition portion 24. Therefore, the wind path resistance can be reduced without the wind blown out by the blade hitting the partition portion 24 and creating a vortex.

  Further, the projection 25 provided on the first blade portion 17 side of the partition portion 24 has a substantially semicircular shape, and since a smooth flow can be realized by reducing the resistance as much as possible by using a smooth curved surface, there is a silent effect.

  The first blowing portion of the first scroll portion of the casing 15 has a plate-like wind direction parallel to a first blowing surface extending from the tongue portion of the first scroll portion to the tip of the first blowing portion. A plate 26 is provided.

  Thus, by providing the plate-like wind direction plate 26 at the first blowing portion of the first scroll portion of the casing 15, the fast-flowing portion that blows out along the outer peripheral side of the casing 15 and the inner peripheral side are provided. Since the relatively slow flow portion can be divided, a rectifying effect can be obtained.

  Moreover, since the wind direction plate 26 provided in the 1st blowing part of the casing 15 is parallel to the 1st blowing surface extended from the tongue part of a 1st scroll part to the front-end | tip of a 1st blowing part, the wind direction board 26 is added. Airflow resistance due to airflow can be kept low, and wind at a relatively slow flow on the inner periphery can be prevented from colliding with the tongue of the scroll and causing significant air loss and vortex generation. It is possible to form a wind path with high rectification effect and low noise.

  As described above, the present invention includes a main body case having an intake port and an exhaust port, and a heat pump provided in the main body case. The heat pump includes a compressor and a radiator sequentially provided downstream of the compressor. A first blower unit that is formed by an expansion unit and a heat absorber, and blows air sucked into the main body case from the intake port to the exhaust port through the radiator, and the main unit from the intake port A second air blowing means for blowing the air sucked into the case to the exhaust port through the heat radiator and the heat absorber in order is provided, and dehumidification is freely performed between the heat radiator and the heat absorber. A rotor is provided, and the dehumidifying rotor is composed of a moisture releasing portion and a moisture absorbing portion, the moisture releasing portion is provided in an air passage between the radiator and the heat absorber, and the moisture absorbing portion is provided between the heat absorber and the exhaust port. Provided in the air path of the radiator and the moisture release The first air blowing means and the second air blowing means have one electric motor disposed in the casing, and one blade fixed to the rotating shaft of the electric motor. The blade is provided with a first blade portion corresponding to the first air blowing means and a second blade portion corresponding to the second air blowing means on both sides of the main plate, and the outer diameter of the first blade portion. Is smaller than the diameter of the second blade part, and the height of the first blade part is higher than the height of the second blade part, and the air is blown to two air paths by one electric motor. Even in the case where the airflow resistances are greatly different, the respective air volume adjustments can be easily performed.

  That is, of the two air paths, the first air path requires a larger air volume than the second air path, but the air path resistance is small, and the second air path has a smaller air volume than the first air path. However, when the air passage resistance is a large air passage, the first blade portion has a smaller blade diameter and a higher blade portion height than the second blade portion, and the second blade portion is the first blade portion. The blade diameter is made larger than that of the blade portion and the height of the blade portion is lowered.

  In this way, since two types of blade diameters and heights of the blade portions are provided on both sides of the main plate, when the first blade portion and the second blade portion are rotated by the electric motor at the same rotational speed, Compared to the second blade, the first blade has a higher air flow but does not generate static pressure. The second blade has a lower air flow than the first blade, but has a lower static pressure. It becomes a feather that can be taken. That is, the first blade portion is an air flow type blade, and the second blade portion is a static pressure blade.

  In conclusion, it is possible to easily adjust to the airflow type and static pressure type blades without increasing the height of the blade portion.

  According to these results, even when the air path resistances of the two air paths are greatly different, the respective air volume adjustments can be easily performed.

  In addition, this eliminates the resistance imbalance between the first blade portion and the second blade portion, so that the motor speed is improved and noise can be reduced by achieving an optimum rotation speed.

  Therefore, it is expected to be utilized as a dehumidifying device for home use or office use.
