  The problem in the conventional example is to further widen the blowing range and to make the wind speed distribution uniform within the blowing range.

  That is, recently, so-called room drying needs for drying laundry in a room with a dehumidifying device or the like are increasing. And the usage method which dries laundry widely and blows air toward the laundry is becoming mainstream, and the expansion of the blowing range is demanded further than the conventional one.

  In the conventional product, for the problem of further expanding the air blowing range, a method of further increasing the mounting inclination of the wind direction changing plate can be considered, but on the other hand, the air is blown only in the wide direction, and the wind speed at the center portion is small. Thus, there are problems such as nonuniformity of the wind speed distribution. Moreover, since it is necessary to enlarge a wind direction change board, there existed problems, such as increase in ventilation resistance and expansion of a product size.

  Therefore, the present invention has an object to make the wind speed distribution uniform within the blowing range while further expanding the blowing range.

  In order to achieve the above object, the dehumidifying apparatus of the present invention has a main body case having a substantially rectangular outlet, a dehumidifying means provided in the main body case, and a blowing means for conveying the air dehumidified by the dehumidifying means. A wind direction changing unit that changes a blowing direction of the air blown from the blowing unit, and the wind direction changing unit includes a plurality of wind direction changing plates that change the blowing direction of the blowing unit in the outlet. A rotating shaft that fixedly supports the wind direction changing plate in a rotatable manner, the rotating shaft extends in a longitudinal direction of the blowout port, and the wind direction changing plate blows a blowing direction with respect to a blowing direction from the blowing port. Mounted at an inclination angle with respect to the blowing direction so as to spread in the longitudinal direction of the outlet, the movable range when rotating the inclined wind direction changing plate is substantially the same circle, and in the longitudinal direction of the outlet. The said wind direction changing plate which is located near the center that, characterized by providing a notch on the upstream side of the blowing direction, thereby is to achieve the intended purpose.

  As described above, the present invention includes a main body case having a substantially rectangular air outlet, a dehumidifying means provided in the main body case, a blowing means for conveying the air dehumidified by the dehumidifying means, and a blowing from the blowing means. A wind direction changing unit that changes the air blowing direction, and the wind direction changing unit includes a plurality of wind direction changing plates that change the blowing direction of the blowing means, and rotates the wind direction changing plate.

  The air blowing means 7 is composed of a scroll-shaped casing 8 that forms an air passage, an impeller 9 that pressurizes and blows air by rotating in the casing 8, and a motor 10 that rotationally drives the impeller 9. It is configured as a sirocco fan.

  The casing 8 has an inflow port 11 through which air flows in and a discharge port 12 through which air flows out, and has a tongue 13 for directing the pressurized air toward the discharge port 12. The discharge port 12 is configured to communicate with the air outlet 2 of the main body case 1.

  The wind direction changing unit 6 is attached to the air outlet 2 of the main body case 1 and is located on the downstream side of the discharge port 12 of the casing 8. The wind direction changing unit 6 is rotatably provided by the rotating means 14. Further, as the rotating means 14, a small motor or the like is used.

  The wind direction changing unit 6 includes a rotating shaft 15 connected to the rotating means 14 and a plurality of wind direction changing plates 16 that are penetrated and fixed to the rotating shaft 15. The rotating shaft 15 is installed so as to extend in the longitudinal direction of the air outlet 2. The wind direction changing plate 16 is fixed to the rotary shaft 15 with the tilt direction reversed to the left and right, and is fixed so that the closer to the end of the rotary shaft 15 the greater the tilt angle with respect to the vertical plane. The ends of the wind direction changing plate 16 are connected by connecting ribs 17, and the strength of the wind direction changing unit 6 is secured by connecting the wind direction changing plates 16.

  Further, since the projected shape of the wind direction changing plate 16 in the direction of the rotation axis 15 is circular, and the movable range when the inclined wind direction changing plate 16 is rotated is substantially circular, the wind direction changing plate 16 can be rotated. ing.

  FIG. 5 shows a control block diagram. A control unit 18 is provided in the main body case 1, and the control unit 18 connects a dehumidifying unit 19, a blowing unit 7, and a rotating unit 14. Each of these means is controlled and driven by the control unit 18, and the dehumidifying device can be operated while switching various operations by the operation of the user of the operation unit 4.

  In the wind direction changing unit 6, the rotation means 14 can select the rotation operation and the stop state by operating the operation unit 4, and can be used with the continuous rotation or blowing direction stopped at a desired angle. Yes.

  In the above configuration, the indoor air sucked from the suction port 3 of the main body case 1 is dehumidified by the dehumidifying means 19, and the dehumidified air flows into the blowing means 7 from the inlet 11 of the casing 8, and the air direction from the outlet 12. Sent to the change unit 6. In the air direction changing unit 6, the air flowing in a straight line flows along the air direction changing plate 16 to change the air direction, and in the vicinity of the air outlet 2, the air flows so as to spread wide in the longitudinal direction of the air outlet 2. Will be.

  FIG. 6 shows a positional relationship of the rewinding direction changing unit 6 that blows the air blowing range wide, and FIG. 7 shows a positional relationship of the rewinding direction changing unit 6 that blows the air blowing range to the spot.

  The user can select the air blowing range by operating the operation unit 4, and can arbitrarily select the air blowing in which the intermediate air blowing range is straight.

  As shown in FIG. 6, the present embodiment is characterized in that a notch portion 20 is provided on the upstream side in the air blowing direction on the wind direction changing plate 16 located near the center in the longitudinal direction of the air outlet 2. Of some of the plurality of wind direction changing plates 16, a part of the thin plate-like wind direction changing plate 16 is shortened to form a notch 20, and in FIG. 5, the air is blown from below, so the notch 20 is provided in the downward direction of the wind direction change unit 6 which is the upstream side of ventilation, and as a result, a space is provided in the lower center portion of the wind direction change unit 6.

  That is, when the attachment inclination angle of the wind direction changing plate 16 is further increased in order to widen the air blowing range, the air is blown only in the end direction in the longitudinal direction of the air outlet 2 and the wind speed in the central portion is reduced. The wind direction changing plate 16 located near the center of the direction is provided with a notch 20 on the upstream side of the air flow, so that the air flow at the center portion is improved and the wind speed at the center portion is suppressed from being reduced. The wind speed can be secured.

  As a result, the air velocity distribution can be made uniform within the air blowing range while further expanding the air blowing range.

  Further, the notch portion 20 of the wind direction changing plate 16 is provided near the tongue portion 13 of the casing 8. The tongue portion 13 is positioned substantially at the center with respect to the air outlet 2 because the air direction of the pressure increased by the impeller 9 rotating in the casing 8 is directed toward the air outlet 2. The vicinity of the tongue 13 is also a portion where the wind speed increases.

  That is, the vicinity of the tongue portion 13 of the casing 8 is a portion where the wind speed is high, and by providing the notch portion 20 in the wind direction changing plate 16 of that portion, an obstacle that causes wind path resistance is placed in the high wind speed portion. This eliminates the possibility of reducing the air path resistance and further reducing the blowing noise.

  Further, in the case of the wind direction changing unit 6 having the same size, the notch portion 20 is provided so that the wind direction changing plate 16 is placed close to the air blowing means 7 while maintaining a distance from the tongue portion 13 of the casing 8. be able to.

  As a result, it is possible to provide a compact dehumidifying device that can widen the blowing range, make the wind speed distribution uniform within the blowing range, and reduce blowing noise.

  Further, the notch portion 20 of the wind direction changing plate 16 is increased toward the vicinity of the center in the longitudinal direction of the air outlet 2. Although the wind speed distribution with respect to the blower outlet 2 is not uniform and the wind speed of the center part is high, the magnitude | size of the notch part 20 is adjusted according to it.

  That is, about the center part of the blower outlet 2, since the wind currently sent may be blown out as it is, the notch part 20 may be enlarged and the air path resistance will be reduced if the notch part 20 is enlarged. be able to. Furthermore, the wind speed distribution can be made uniform by gradually increasing the notches 20 in the adjacent wind direction changing plates toward the enlarged notches 20.

  As a result, the air velocity distribution can be made uniform within the air blowing range while further expanding the air blowing range.

  Further, a connecting rib 17 that connects the end portions of the wind direction changing plate 16 is provided.

  That is, the strength is increased by connecting and integrating the wind direction change plates 16, and the deformation of the wind direction change plate 16 due to the wind pressure and the bending of the rotating shaft 15 are prevented, thereby suppressing the ventilation resistance of the wind direction change unit. it can. Furthermore, since the strength of the wind direction changing plate 16 is increased and minute vibrations are suppressed and no noise or vibration is generated, low noise can be realized.

  As a result, it is possible to provide a dehumidifying device that can widen the blowing range, make the wind speed distribution uniform within the blowing range, and reduce blowing noise.

  Further, the inclination angle of the wind direction changing plate 16 with respect to the blowing direction is changed from the upstream side to the downstream side of the blowing.

  That is, by setting the inclination angle of the wind direction changing plate 16 so that the upstream side of the blowing is aligned with the direction in which the air is blown from the blowing means 7, the inclination angle is changed in the direction in which the air is to be blown toward the downstream of the blowing. The wind can be prevented from abruptly colliding with the wind direction changing plate 16, and the air blowing range can be expanded while reducing the wind path resistance. Reducing air path resistance is effective in reducing blowing noise.

  As a result, it is possible to provide a dehumidifying device that can widen the blowing range, make the wind speed distribution uniform within the blowing range, and reduce blowing noise.

  Moreover, the inclination angle with respect to the blowing direction of the wind direction changing plate 16 is increased from the upstream side to the downstream side of the air blowing.

  In other words, the inclination angle of the wind direction changing plate 16 is set so that the upstream side of the blowing is aligned with the direction of the air blown from the blowing means 7, and the inclination angle is directed toward the longitudinal direction of the outlet 2 toward the downstream of the blowing. By increasing the size, it is possible to prevent the wind from abruptly colliding with the wind direction changing plate 16 and to expand the air blowing range while reducing the air path resistance. Reducing air path resistance is effective in reducing blowing noise.

  As a result, it is possible to provide a dehumidifying device that can widen the blowing range, make the wind speed distribution uniform within the blowing range, and reduce blowing noise.

Thus, the air velocity distribution can be made uniform in the air blowing range while further expanding the air blowing range.

  In other words, when the mounting inclination angle of the wind direction change plate is further increased in order to widen the blowing range, the air is blown only at the end portion in the width direction and the wind speed at the center portion is reduced, but it is located near the center of the outlet in the width direction. By providing the wind direction change plate with a notch on the upstream side of the air flow, it is possible to improve the escape of the wind at the center portion, suppress the decrease in the wind speed at the center portion, and secure the wind speed.
