  As described above, the conventional dehumidifying device is highly evaluated for clothes drying and the like. However, in the conventional dehumidifying device, a louver is provided at the air outlet portion of the main body case, and this louver is reciprocated by a stepping motor or the like. The angle of the air blowing direction from the air outlet is changed from the horizontal direction to the vertical upward direction. However, depending on the positional relationship between the louver and the shaft that rotatably fixes the louver, the louver accelerates due to its own weight, and the rotational speed increases during the rotation, and the louver rotates at a constant speed. For this reason, there is a problem that the clothes after washing are not evenly blown and uneven drying occurs.

  Therefore, conventionally, a shaft is provided at the center of the louver so that the center of gravity of the louver comes to the shaft, and the louver is reciprocally rotated at a constant speed when the louver is rotated, but in that case, the blowing direction cannot be changed.

  In order to achieve this object, the present invention provides a main body case having a blower opening that opens upward, a dehumidifying means provided in the main body case, and a movable covering the upper part of the blower opening at a predetermined interval. A free louver, and a drive means for rotating the louver, and having shaft portions on both side surfaces of the louver, and the shaft portions are provided so as to be offset from either the front side or the rear side of the louver. The louver is rotatably fixed to the main body case by the shaft portion, and one of the shaft portions is connected to the driving means via the main body case, and a louver rotation stabilizing means is provided on the louver. To achieve the initial objective.

  The present invention provides a main body case having a blower opening that opens upward, a dehumidifying means provided in the main body case, a movable louver that covers the upper portion of the blower opening at a predetermined interval, and the louver Drive means for rotating, and having a shaft portion on both side surfaces of the louver, the shaft portion is provided to be offset from either the front side or the rear surface side of the louver, and the louver is the shaft portion. The shaft portion is rotatably fixed to the main body case, and either one of the shaft portions is connected to the driving means via the main body case, and the louver is provided with a louver rotation stabilizing means. By changing the air blowing direction from the horizontal direction to the vertically upward direction from the entire area, and performing the change at a constant speed, the air can be evenly applied to the clothes after washing, and uneven drying can be suppressed. Clothes drying ability It can be improved.

  That is, since the louver rotation stabilizing means is provided in the louver, in order to change the air blowing from almost the entire area of the air blowing port to the air blowing direction from the horizontal direction to the vertically upward direction, Also when the louver is rotated, the rotation of the louver is unlikely to be accelerated when the louver is rotated.

  Based on these results, by blowing air from almost the entire area of the air blowing port, changing the air blowing direction from the horizontal direction to the vertical upward direction, and performing the change at a constant speed, the air is evenly applied to the clothes after washing and dried. Kimura can be suppressed.

  Further, a part of the air sucked into the main body case 1 by the fan 8 is heated and passes through the discharge portion of the dehumidification rotor 6 in a state where the relative humidity is lowered, and at this time, the discharge humidity from this discharge portion is reduced. Then, it is guided to the evaporator 5 and cooled by the evaporator 5, where moisture is condensed.

  The condensed water is stored in the tank 10 through the drain pan 9.

  Further, the moisture not condensed by the evaporator 5 is absorbed by the moisture absorbing portion of the dehumidifying rotor 6, and this moisture absorbing portion becomes the above-mentioned releasing portion by the rotation of the dehumidifying rotor 6, thereby re-releasing the trapped moisture to the heated air. Then, it is cooled by the evaporator 5, and moisture is condensed and removed.

  And by such dehumidification operation | movement, dry air is produced | generated and this dry air is ventilated from the above-mentioned ventilation port 3 to the room | chamber interior behind the main body case 1. As shown in FIG.

During the reciprocating rotation from the horizontal direction to the vertical upward direction, the air blowing rear end 11a of the louver 11 covers almost the entire area of the air blowing port 3 during the reciprocating rotation. The blowing direction can be changed from the horizontal direction to the vertical upward direction.

  Further, since the louver rotation stabilizing means 14 is provided on the lower side of the shaft portion 13 between the both side surfaces 12 of the louver 11 so as to be offset toward the blowing rear end 11a side of the louver 11, the louver turning stabilizing means 14 and the blowing rear end are provided. 11a balances with the air blowing front end 11b with the shaft portion 13 as the center, that is, regardless of the position of the louver 11, the position of the louver center of gravity 18 is maintained substantially in the vicinity without being separated from the shaft portion 13, Since the louver center of gravity 18 does not move back and forth with respect to the vertical direction of the shaft portion 13, no rotational force is applied to the driving means 17 when the louver 11 is rotated, and the louver 11 is rotated while maintaining a constant speed. The direction can be changed.

  Further, since the distance between the louver rotation stabilizing means 14 and the shaft portion 13 is longer than the distance between the louver 11 and the shaft portion 13, the louver rotation stabilizing means 14 is made of the same material as the louver 11. The volume is smaller than that of the louver 11, and it is possible to achieve balance even with a light weight, and it is possible to suppress the occurrence of airflow resistance against the flow of airflow from the air outlet 3.

  Further, when the material of the louver rotation stabilizing means 14 is metallic having a density higher than that of the louver 11 material, the volume of the louver rotation stabilizing means 14 can be further reduced, and the flow of air from the blower port 3 can be reduced.

Between the side surfaces 12, the air blow rear end 19 a of the louver rotation stabilizing means 19 and the air blow rear end 11 a of the louver 11 are blown around the shaft portion 13 because they are provided in parallel to the louver 11 and between the side faces 12. The front end 19b and the air blowing front end 11b are balanced, that is, regardless of the position of the louver 11, the position of the louver center of gravity 18 is maintained substantially in the vicinity of the shaft portion 13 without being separated. Since the louver center of gravity 18 does not move back and forth with respect to the vertical direction, no rotational force is applied to the driving means 17 when the louver 11 is rotated, and the louver 11 has a constant speed. Rotation to be able to change the blowing direction I.

  Further, since the louver rotation stabilizing means 19 has a flat plate shape, wind force always acts in the direction opposite to the rotation direction of the louver 11 when the air blown from the air blowing port 3 hits the louver rotation stabilizing means 19. Further, no rotational force is applied to the driving means 17 when the louver 11 is rotated, and the louver 11 can be further rotated at a constant speed to change the blowing direction.

  As shown in FIG. 10, when the louver 11 is rotated and the position of the louver center of gravity 18 is in the direction perpendicular to the shaft portion 13, the long side of the substantially elliptical flat plate 20 a and the leaf spring 20 c are in contact with each other. When the position of the louver center of gravity 18 is closer to the opening direction of the louver 11 than the position of the shaft portion 13 in the vertical direction, the substantially elliptical flat plate 20a pushes the leaf spring 20c, and the louver 11 springs in the rotational direction in which the louver 11 is closed. Work. Conversely, when the position of the louver center of gravity 18 is closer to the closing direction of the louver 11 than the position of the shaft portion 13 in the vertical direction, a spring force acts on the louver 11 in the rotational direction in which the louver 11 opens.

  In such a configuration, it is possible to change the blowing direction of almost all the blowing from the blowing port 3 from the horizontal direction to the vertical upward direction, and the louver center of gravity 18 is in the vertical direction of the shaft portion 13 when the louver 11 is rotated. Rotation generated in the driving means 17 due to the weight movement of the louver 11 before and after the louver 11 is rotated by a spring force acting on the louver 11 in a direction opposite to the direction in which the louver 11 rotates. The rotational force in the direction can be reduced, and the louver 11 can be rotated at a constant speed to change the blowing direction.

  With these results, even with a simple configuration of the louver of the dehumidifier, it is possible to change the blowing direction from almost the entire area of the blowing port from the horizontal direction to the vertical upward direction, and to perform the change at a constant speed. It is possible to provide a dehumidifier equipped with an inexpensive louver that can uniformly blow air to clothes after washing that has been dried over a wide area and can prevent uneven drying.

  The dehumidifying apparatus of the present invention changes the blowing direction from almost the entire area of the blowing port from the horizontal direction to the vertically upward direction, and performs the change at a constant speed, so that it can be applied to clothes after washing that has been widely dried. Since air blow can be applied evenly and drying unevenness can be suppressed, odors peculiar to room drying due to drying unevenness can be reduced in the indoor drying of the laundry, and the usability is further enhanced. Therefore, it will be widely used in various drying equipment.
