  For this reason, the temperature rise of the cold wind by mixing of warm air can be suppressed, and the cool wind feeling in the cold wind dehumidification mode operation | movement of a dehumidifier with a cold wind function can be improved.

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

(Embodiment 1)
As shown in FIGS. 1 and 2, 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 exhaust port 2 of the main body case 3 includes a first exhaust port 2A provided on the upper surface of the main body case 3 and a second exhaust port 2B provided on the front surface of the main body case 3 different from the first exhaust port 2A. Has been.

  The heat pump 4 is formed by sequentially connecting a compressor 5 and a radiator 6, an expansion means 7, and a heat absorber 8 that are sequentially provided downstream of the compressor 5.

  Between the radiator 6 and the heat absorber 8, a double suction type air blowing means 9 is provided.

  As shown in FIG. 3, the double-suction type air blowing means 9 includes a casing 13 and both suction fans 14, and a radiator-side fan suction port 15 is provided on a side surface of the casing 13 on the radiator 6 side. A heat absorber side fan suction port 16 is provided on the side surface on the opposite side of the heat absorber 8 side.

  In the main body case 3, air sucked into the main body case 3 from the intake port 1 is blown from the radiator 6 and the radiator-side fan suction port 15 to the first exhaust port 2 </ b> A via the blowing means 9. The air that has been sucked into the main body case 3 from the exhaust air passage 18 and the air intake port 1 is sequentially transferred from the radiator 6, the heat absorber 8, and the heat absorber side fan intake port 16 to the second exhaust port 2 </ b> B through the air blowing means 9. A dehumidifying cold air passage 17 for blowing air.

  Further, both suction fans 14 of the both suction type air blowing means 9 are provided with two blade sets 21 and 22 disposed on both surfaces of the main plate 20 mounted on the rotating shaft 19 of the motor. 17 and the exhaust air passage 18 are partitioned.

  Further, as shown in FIG. 6, the main plate 20 of the suction fans 14 is formed in substantially the same plane in a circular opening 28 formed in the casing partition plate 23 that partitions the dehumidifying cold air passage 17 and the exhaust air passage 18. In the vicinity of the gap between the main plate 20 and the inner edge of the opening 28 of the casing partition plate 23, wind mixing preventing means 24 is provided, which will be described in detail later.

  Further, in the present embodiment, as shown in FIG. 1, a dehumidifying portion 11 of a dehumidifying rotor 10 is provided in the dehumidifying cold air passage 17 between the radiator 6 and the heat absorber 8, and this dehumidifying rotor The 10 moisture absorption parts 12 are provided between the heat absorber 8 and the first exhaust port 2A and the second exhaust port 2B.

  That is, the refrigerant pressurized by the compressor 5 is sent to the radiator 6 where the air taken into the main body case 3 from the intake port 1 is heated.

  Next, the refrigerant that has passed through the radiator 6 reaches the expansion means 7 and then returns to the compressor 5 via the heat absorber 8.

  The air heated by the heat radiator 6 then passes through the moisture releasing portion 11 of the dehumidifying rotor 10 and flows to the heat absorber 8 in a state where moisture from the moisture releasing portion 11 is taken away.

  First, the air that has passed through the moisture release portion 11 of the dehumidifying rotor 10 is condensed in the heat absorber 8, and this condensed water is stored in the water storage tank 37.

  Now, the air that has passed through the heat absorber 8 is cooled to a low temperature by the heat absorber 8, but the humidity is extremely high although the temperature is low. This low-temperature air containing high humidity then passes through the hygroscopic section 12 of the dehumidifying rotor 10, and the hygroscopic section 12 is driven to rotate by the driving means 38 so that the upper part of FIG. The moisture release portion 11 of the product has already released moisture and the humidity is low.

  For this reason, it is possible to absorb moisture from air in a state where the humidity is extremely high although the temperature is low, and thus the dehumidifying effect can be made extremely high.

  A feature of this embodiment is that, as shown in FIG. 6, the wind mixing prevention means 24 is provided in the both suction type air blowing means 9 for sending air to the exhaust air passage 18 and the dehumidifying cold air passage 17.

  That is, the peripheral edge portion of the main plate 20 (not shown) of both the suction fans 14 is protruded outward from the blade outer peripheral surface 25 formed by the blades of the both suction fans 14, so that the blade outer peripheral surface 25 has a donut shape. The fan rectifying piece 26 is provided, and the fan rectifying piece 26 constitutes the air mixing preventing means 24.

  In other words, the outer end portion 27 of the fan rectifying piece 26 is brought close to the inner edge of the opening 28 of the casing partition plate 23 to reduce the gap between the two. The reason is that a gap 29 is provided between the outer end portion 27 of the fan rectifying piece 26 and the opening 28 of the casing partition plate 23 in order to rotate both the suction fans 14. Because the fan rectifying piece 26 formed on the blade outer peripheral surface 25 of the suction fan 14, the cold air and the warm air blown from both the suction fans 14 are rectified in the direction of going straight downstream and are blown into the casing 13. The warm air flowing in the exhaust air passage 18 is less likely to flow into the dehumidifying cold air passage 17 through the gap 29. As a result, it is possible to improve the cool air feeling by preventing the temperature of the cool air from rising due to the mixing of warm air.

  Further, in the present embodiment, as shown in FIG. 6, the thickness of the fan rectifying piece 26 is larger than the thickness of the casing partition plate 23.

  That is, by making the thickness of the fan rectifying piece 26 larger than the thickness of the casing partition plate 23, the dehumidifying cold air passage 17 and the exhaust air passage 18 partitioned by the fan rectifying piece 26 and the casing partition plate 23 are cooled and heated. Since it becomes wider in the direction of the wind, cold air and warm air flow through these air paths more smoothly. Thereby, the warm air flowing in the exhaust air passage 18 is less likely to flow into the dehumidifying cold air passage 17 through the gap 29. As a result, it is possible to improve the cool air feeling by preventing the temperature of the cool air from rising due to the mixing of warm air.

  Of course, in the present embodiment, the thickness of the fan rectifying piece 26 may be substantially the same as the thickness of the casing partition plate 23.

  That is, by making the thickness of the fan rectifying piece 26 substantially the same as the thickness of the casing partition plate 23, the fan rectifying piece 26 and the casing partition plate 23 are planar, and no convex surface is generated. The flow of the cool air and the warm air flowing through the exhaust air passage 18 is less likely to be disturbed.

  For this reason, the cool air and the warm air blown from both the suction fans 14 are rectified in the direction of going straight downstream and are blown into the casing 13, so that the warm air flowing in the exhaust air passage 18 passes through the gap 29. Therefore, it is difficult to flow into the dehumidifying cold air passage 17, and as a result, the temperature rise of the cold air due to the mixing of the hot air can be prevented and the cold air feeling can be improved.

  In the present embodiment, there is provided switching means 35 for switching the exhaust port of the dehumidifying cold air passage 17 to the first exhaust port 2A and the second exhaust port 2B. In other words, the dehumidifying mode operation in which the warm air flowing through the exhaust air passage 18 and the cold air flowing through the dehumidifying cold air passage 17 are blown in the same direction as shown in FIG. 4 and in different directions as shown in FIG. It is set as the structure which can be switched with the cold wind dehumidification mode driving | running which blows off.

  That is, in the dehumidifying mode operation in which the hot air flowing through the exhaust air passage 18 and the cold air flowing through the dehumidifying cold air passage 17 are blown in the same direction, both hot air and cold air can be blown toward the laundry. The laundry can be dried earlier than the cold air dehumidifying mode operation in which the cold air is blown in different directions. Since the dehumidifying mode operation and the cold air dehumidifying mode operation can be switched by the switching means 35, it is possible to select an operation mode suitable for the purpose of use.

  Further, in the present embodiment, as shown in FIG. 2, a wind direction louver 36 is provided in at least one of the first exhaust port 2A and the second exhaust port 2B.

  That is, by providing a rotatable wind direction louver 36 in at least one of the first exhaust port 2A and the second exhaust port 2B, in the cool air dehumidification mode operation, the cool air and the warm air are blown away from each other. By taking it out, it is possible to suppress the flow of hot air to the cold air supply side and improve the cool air feeling.

(Embodiment 2)
FIG. 7 shows another embodiment of the present invention, and a first bent portion 31 protruding in a right angle direction on the exhaust air passage 18 side is provided on the outer edge of the fan rectifying piece 26.

  That is, the hot air flowing through the exhaust air passage 18 is bent in the direction away from the dehumidifying cold air passage 17 in the vicinity of the upstream side of the gap 29, so that the hot air flowing through the exhaust air passage 18 is dehumidified cold air through the gap 29. It is difficult to flow into the path 17. As a result, it is possible to improve the cool air feeling by preventing the temperature of the cool air from rising due to the mixing of warm air.

  In the present embodiment, the inner projecting surface 33 of the first bent portion 31 has a curved shape.

  In other words, by forming the inner projecting surface 33 of the first bent portion 31 into a curved shape, this curved surface is bent when the hot air flowing through the exhaust air passage 18 is bent in the direction away from the dehumidifying cold air passage 17 in the vicinity of the upstream side of the gap 29. The direction of hot air can be smoothly bent along the shape.

  For this reason, the warm air flowing through the exhaust air passage 18 flows more smoothly in the vicinity of the upstream side of the gap 29 in the direction away from the dehumidifying cold air passage 17. As a result, the hot air flowing in the exhaust air passage 18 becomes difficult to flow into the dehumidifying cold air passage 17 through the gap 29, and as a result, the temperature rise of the cold air due to the mixing of the hot air is prevented and the cold air feeling is improved. It can be done.

  Moreover, in this Embodiment, said 1st bending part 31 is made into the shape which thickness becomes thin gradually toward a front-end | tip.

  That is, the inner projecting surface 33 of the first bent portion 31 has a curved surface shape, and the first bent portion 31 has a shape that gradually decreases in thickness toward the tip, so that the dehumidified cold air is closer to the gap 29. The exhaust air passage 18 can be bent in a direction away from the passage 17.

  That is, the warm air flowing through the exhaust air passage 18 flows toward the direction away from the dehumidifying cold air passage 17 at a position closer to the gap 29. For this reason, the hot air flowing in the exhaust air passage 18 becomes difficult to flow into the dehumidifying cold air passage 17 through the gap 29, and as a result, the temperature rise of the cold air due to the mixing of the hot air is prevented and the cold air feeling is improved. It can be made.

(Embodiment 3)
FIG. 8 shows still another embodiment of the present invention, and the fan rectifying piece 26 has a shape having a second bent portion 32 in which an outer edge of the first bent portion 31 protrudes further outward.

  That is, the fan rectifying piece 26 has a shape having a second bent portion 32 having a shape that the outer edge of the first bent portion 31 protrudes further outward and bends along the outer peripheral surface 25 of the blade. Thus, the shielding property between the dehumidifying cold air passage 17 and the exhaust air passage 18 in the vicinity of the gap 29 is further enhanced. Thereby, the warm air flowing in the exhaust air passage 18 is less likely to flow into the dehumidifying cold air passage 17 through the gap 29. As a result, it is possible to improve the cool air feeling by preventing the temperature of the cool air from rising due to the mixing of warm air.

  As described above, the present invention is configured by sequentially connecting a main body case having an intake port and first and second exhaust ports, and a compressor, a radiator, an expansion means, and a heat absorber in the main body case. A heat pump, an exhaust air passage formed in the main body case and for blowing air sucked into the main body case from the intake port to the first exhaust port through the radiator, and the main body case A dehumidifying cool air passage formed inside and for blowing air sucked into the main body case from the intake port to the second exhaust port via the radiator and the heat absorber, and the dehumidifying cool air passage and the exhaust Each of the air passages is configured to be a double-suction type air-blowing unit in which blades are respectively disposed on both surfaces of a main plate mounted on a rotating shaft of the motor. The main plate is arranged in a plane with the partition plate at the opening of the partition plate that partitions the exhaust air passage and the dehumidifying cool air passage, and wind mixing preventing means is provided on the outer periphery of the main plate or in the vicinity thereof. Since it is provided, it is possible to prevent warm air from flowing into the dehumidifying cold air passage.

  For this reason, the temperature rise of the cold wind by mixing of warm air can be suppressed, and the cool wind feeling in the cold wind dehumidification mode operation | movement of a dehumidifier with a cold wind function can be improved.

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