JP-A-7-139759 (first page, FIGS. 1 and 2)

  In such a wind direction change device, the laundry cannot be dried on the front of the dehumidifier body, and it is not easy to use, and dry air can be intermittently applied to clothes that have been dried in large quantities. However, it is not possible to continue to apply a wide range of dry air continuously, and the blowout range cannot be adjusted.Therefore, there is a problem that the range and arrangement for drying clothes should be considered according to the blowout range of the dehumidifier. It is required that the air blowing range can be freely selected.

  Also, because there are differences in the drying speed depending on the type and material of clothing, there is a problem that uneven drying occurs when uniform drying air is applied, and uneven drying does not occur when simultaneously drying clothing with different drying speeds Is required.

  In addition, when it is desired to dry a small amount or thick clothing such as a piece of jeans in a short time, a wide air blowing range increases waste, resulting in the problem of not only wasting energy but also a longer drying time. In addition, it is required that dry air can be concentrated on a small amount of laundry and thick clothing.

  The present invention solves the above-mentioned conventional problems, and by allowing the air blowing range of dry air to be arbitrarily selected, dry air is continuously applied to the clothing regardless of the range or arrangement in which the clothing is lined up and dried. It can be supplied, and the drying air supply time can be changed at the clothes drying position to prevent drying unevenness, and dry air can be supplied intensively for small or thick laundry. It aims at providing the wind direction change apparatus which can reduce drying time.

  In order to achieve the above object, the wind direction changing device of the present invention has a main body provided with a blowing means, an air outlet provided in the main body, an air direction changing unit provided in an air passage of the air outlet, and the air direction changing device. A rotating shaft that supports the unit in a rotatable manner and a plurality of wind direction changing plates that are penetrated by the rotating shaft and fixed at an inclination. The direction of the inclination of the wind direction changing plate is reversed from the middle of the rotating shaft. Is provided.

  Another means is that a reference wind direction change plate orthogonal to the rotation shaft is provided in the middle of the rotation shaft, and the inclination directions of the wind direction change plates located on both sides of the reference wind direction change plate are reversed.

  The other means is such that the longer the diameter of the oval, the larger the wind direction changing plate located closer to the end of the rotating shaft.

  The other means is that the wind direction change plate has a projected outer shape in the direction of the rotation axis, in which the wind direction change plate on the center side is larger than the wind direction change plate on the end side.

  Another means is provided with a connecting rib for connecting the end portions of the wind direction changing plate.

  The other means is provided with a rotating means for rotating the rotating shaft, and the rotation speed of the rotating means can be changed.

The inclination angle of the wind direction changing plate located on the side and the discharge angle of the fan casing are substantially matched.

  Another means is that the air blowing means has a fan casing, the air direction changing unit is provided in the vicinity of the discharge opening of the fan casing, and the tongue portion of the fan casing is located when the air direction changing unit is in a position to concentrate the air blowing range. The distance between the wind direction changing plate closest to the tongue and the tongue is narrowed to prevent the wind from spreading.

  With these means, it is possible to supply the dry air continuously to the garment regardless of the range and arrangement in which the garment is laid side by side by making it possible to arbitrarily select the air blowing range of the dry air, and the drying speed. There is a wind direction change device that can prevent uneven drying even when clothes of different sizes are dried at the same time, and can reduce drying time by supplying dry air intensively even for small or thick laundry can get.

  According to the present invention, the air blowing range of the dry air can be arbitrarily selected from diffusion to concentration. Therefore, for laundry that has been widely dried, the drying air is diffused to dry a wide range of laundry. Air can be supplied evenly, and for a small amount of laundry such as a piece of jeans, by concentrating the dry air, it is possible to eliminate unnecessary air blowing and supply dry air with a high wind speed for drying. It is possible to provide a wind direction changing device that can shorten the time and can appropriately cope with various clothes drying scenes.

  Further, since the dry air can be supplied over a wide range or in a concentrated manner, the dry air can be effectively supplied not only to the dehumidification of the entire room but also to the inside of the closet.

  Also, since dry air is blown out from the air outlet centrally and centrally around the reference air direction change plate of the air direction change unit, the dry air is supplied by selecting the blowing method according to the shape and material of the clothing. Therefore, it is possible to provide a wind direction changing device that is effective in preventing drying unevenness and shortening the drying time.

  Moreover, low noise can be realized by suppressing the draft resistance of the wind direction changing unit.

  In addition, when the wind direction changing unit is continuously rotated, if air that is difficult to dry at the center and clothes that are easy to dry are dried at the left and right ends, dry air can be effectively supplied and the clothes can be dried without unevenness in drying. It is possible to provide a wind direction changing device that is effective.

  Also, if the clothing to be dried is easy to dry, increase the rotation speed of the wind direction changing unit, and if the material is difficult to dry, reduce the rotation speed to select the rotation speed according to the type of clothing. By doing, drying efficiency can be improved.

  Further, when it is desired to diffuse the air blowing range of the wind direction changing unit, the dry air can be diffused with low noise while having a compact configuration.

At the rotational position where the wind direction changing plate spreads toward the downstream side at the air outlet, the dry air diffuses along the wind direction changing plate and blows out, and at the rotational position where the air direction changing plate becomes narrower toward the downstream side, the dry air flows in the wind direction. At the intermediate position where the distance between the air direction change plates is not wide or narrow toward the downstream side, the air flows in the same direction from the upstream side to the downstream side, and the dry air is blown out substantially in parallel. It has the action.

  In addition, a reference wind direction change plate perpendicular to the rotation axis is provided in the middle of the rotation axis, and the direction of the inclination of the wind direction change plate located on both sides of this reference wind direction change plate is reversed. Centering on the wind direction changing plate, the dry air can be diffused or concentrated and blown out in the intended blowing area.

  In addition, the shape of the inclined wind direction changing plate is an oval shape, and the movable range when rotating the inclined wind direction changing plate is substantially circular, and it can be installed compactly without enlarging the outlet. Has an effect.

  Also, the wind direction changing plate closer to the end of the rotating shaft has a larger ellipse major axis, and the outside wind direction changing plate changes the angle of the blown air greatly when expanding or concentrating the air blowing range. Therefore, it is possible to reliably adjust the air blowing range of the dry air.

  In addition, the projected external shape of the wind direction change plate in the rotation axis direction is such that the wind direction change plate on the center side is larger than the wind direction change plate on the end side, and the wind direction change plate on the center side is the wind direction change plate on the end side. Compared with, the longer diameter dimension is relatively small and the wind direction changing function is inferior, but by increasing the projected outline of the wind direction changing plate on the center side, not only the longer diameter dimension but also the entire area can be expanded, so the wind direction change It has the effect of eliminating the function imbalance.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

(Embodiment 1)
As shown in FIGS. 1 to 7, the main body 1 has a dehumidifying means 9 for drying indoor air and a blowing means 3 for conveying the dry air dehumidified by the dehumidifying means 9. The dehumidifying means 9 and the blowing means 3 are When the operation unit 10 is input, the operation is controlled by the control unit 11.

  A blower outlet 2 for blowing dry air is opened at the upper part of the main body 1, and the air direction changing unit 4 is arranged close to the discharge side of the blowing means 3 so as to cross the upstream side of the blower outlet 2.

  The wind direction changing unit 4 is rotatably provided by a small motor 6 serving as a rotating means, and the small motor 6 is driven and controlled by a control unit 11. In addition, the wind direction changing unit 4 can select a rotation operation and a stopped state by operating the operation unit 10 and can be used with the continuous rotation or blowing direction stopped at a desired angle.

  The wind direction changing unit 4 includes a rotating shaft 8 connected to the small motor 6, a single reference wind direction changing plate 5a that is penetrated by the rotating shaft 8 and a plurality of wind direction changing plates 5, and a reference wind direction. The change plate 5a is located in the vicinity of the center of the discharge port of the blower means 3 and is fixed to the rotary shaft 8 so as to form a circular flat plate. The wind direction changing plate 5 is fixed to the left and right of the reference wind direction changing plate 5a with the inclination direction being opposite to each other, and has an elliptical flat plate shape. Further, the closer the wind direction changing plate 5 is to the end of the rotating shaft 8, the larger the inclination angle with respect to the vertical plane, and the longer diameter of the oval shape is also larger. The end portions of the reference wind direction changing plate 5 a and the wind direction changing plate 5 are connected by connecting ribs 12, and the connecting ribs 12 are installed at both ends of the long diameter of the wind direction changing plate 5 and substantially parallel to the rotating shaft 8.

  Further, the projection shape of the wind direction changing plate 5 in the direction of the rotation axis 8 is circular, and the projected outer shape of the plurality of wind direction changing plates 5A fixed to the center side of the rotation shaft 8 is the rotation shape of the rotation axis 8 as shown in FIG. By making the dimensions larger than the projected external shape of the plurality of wind direction changing plates 5B and 5C fixed to the end side, the wind direction changing plate 5A having a small inclination angle on the central side becomes the wind direction changing plates 5B and 5C having a large inclination angle on the outside. On the other hand, the relative difference in dimensions and shape is reduced.

  The wind direction changing unit 4 is rotationally controlled by the small motor 6 via the rotary shaft 8, but by operating the operation unit 10, the control unit 11 can change the rotation speed of the small motor 6. The rotation speed can be changed according to the material of the clothes to be dried.

  Further, when the wind direction changing unit 4 is in a stopped state and the air blowing range is expanded with the downstream side of the wind direction changing plate 5 facing outward, the tongue of the fan casing 7 of the blowing means 3 is shown in FIG. The inclination angle of the wind direction changing plate 5b whose end portion is close to the portion 7a and the air blowing angle in the vicinity of the tongue portion 7a are substantially the same.

  When the air direction changing unit 4 is stopped and the air blowing range is concentrated with the downstream side of the air direction changing plate 5 facing inward, the tongue of the fan casing 7 of the air blowing means 3 is shown in FIG. The distance between the wind direction changing plate 5d closest to the portion 7a and the tongue 7a is minimized.

  In the above configuration, when operating the main body 1, the operation unit 10 is operated to send an input signal to the control unit 11, and the dehumidifying unit 9 and the blowing unit 3 are driven by the control unit 11. When the air blowing means 3 is activated, the room air sucked from the back of the main body 1 is dehumidified by the dehumidifying means 9, and the dry air passes through the wind direction changing unit 4 and is discharged from the air outlet 2. At this time, as shown in FIG. 7, in the initial state, the air direction changing unit 4 is set to a standard air blowing range, and is blown out from the air outlet 2 substantially in parallel. Furthermore, when changing the ventilation range according to the suspended range of the clothes to be dried, operating the operating unit 10 and rotating the wind direction changing unit 4 expands or reduces the ventilation range. By stopping the rotation when it reaches the range, it is possible to adjust so that dry air can be supplied to all the clothes without excess or deficiency.

  When the amount of clothes to be dried is extremely small or thick clothes are to be dried in a short time, the wind speed is increased by rotating the wind direction changing unit 4 to set the air blowing range to the narrowest state. Since the dry air can be concentrated and blown on the clothes, it can be dried in a short time using the dry air effectively.

  In addition, in order to dehumidify and dry the room, the air blowing range is expanded to spread the dry air, and in order to dehumidify local areas such as closets and shoe racks, the air blowing range is narrowed and the air blowing speed is increased. By using it with concentrated drying, it is possible to use it effectively other than drying clothes.

  Next, when the wind direction changing unit 4 is continuously rotated, a repetitive operation is performed in which the air blowing range sequentially changes from standard to expanded, standard, narrow, standard,. The wind blown at this time is for expanding or reducing the blowing range around the reference wind direction changing plate 5a provided in the wind direction changing unit 4, and the dry air passing in the vicinity of the reference wind direction changing plate 5a is always the same. Since the air is blown in the direction, the dry air is constantly supplied, and the dry air passing through the air direction changing plate 5 near the end of the air direction changing unit 4 is intermittently supplied within the blowing range. Therefore, by suspending thick clothing or the like in front of the reference wind direction changing plate 5a and suspending clothes that are easy to dry in a range outside the center of the air blowing range, clothes having different drying speeds are simultaneously dried. However, a drying operation without drying unevenness can be performed.

  The wind direction changing plate 5 of the wind direction changing unit 4 is disposed so as to be inclined so as to have different inclination directions on the left and right sides with a reference wind direction changing plate 5a vertically attached to the middle of the rotating shaft 8 as well as the rotating shaft 8. As the wind direction changing plate 5 is located closer to the end, the mounting inclination angle is larger.

  When the wind direction changing plate 5 is used at a position spreading toward the downstream side, the dry air from the blowing means 3 is diffused uniformly and at a wide angle through the wind direction changing plate 5 and blown out from the outlet 2. Can do. At this time, the air direction changing plate 5b in the vicinity of the tongue portion 7a of the fan casing 7 is set to an inclination angle substantially coincident with the blowing angle of the fan casing 7, so that the dry air is smoothly diffused without resistance and noise is generated. Can be suppressed.

  Further, when the wind direction changing plate 5 is used at a position where it converges narrowly toward the downstream side, the dry air is intensively blown out at a high speed through the wind direction changing plate 5 and, as described above, short when there is little clothing. Can dry in time. However, since the wind pressure applied to the wind direction changing plate 5 is significantly higher than that of the diffusion, the wind direction changing plate 5d located in the vicinity of the tongue portion 7a is dimensionally related to the gap between the fan casing 7 and the gap. By doing so, it is possible to reduce the leakage of dry air to the periphery, and it is possible to concentrate and blow out on clothes and the like while ensuring the amount of dry air.

  In addition, as shown in FIG. 5, when the wind direction changing plate 5 is in the middle of diffusion and concentration, the direction of the wind direction changing plate 5 is different in the horizontal plane, but does not become the resistance of the dry air flowing through the air outlet 2. Therefore, the dry air passing through the wind direction changing plate 5 can be blown upward substantially in parallel from the entire outlet 2.

  In addition, connecting ribs 12 for connecting the long-diameter opposite ends of each wind direction changing plate 5 are installed, and the connecting ribs 12 are provided substantially parallel to the rotating shaft 8 so that the wind direction changing plates 5 are connected and integrated. Thus, the overall strength of the wind direction changing unit 4 can be increased, deformation of the wind direction changing plate and bending of the rotating shaft due to wind pressure can be prevented, and minute vibrations of the wind direction changing plate 5 can be suppressed. Noise and vibration can be prevented from being generated.

  Moreover, since the shape of the inclined wind direction changing plate 5 is an ellipse, the movable range when the inclined wind direction changing plate is rotated becomes a substantially circular shape, and it can be installed compactly without enlarging the outlet.

  In the present embodiment, the position where the air outlet 2 is provided is the upper part of the main body 1, but the same effect can be obtained even if it is provided on the side or lower part of the main body 1.

  Moreover, although the shape of the wind direction changing plate 5 is circular or oval, the shape of the wind direction changing plate 5 is not limited, and may be a polygon.

  In the present invention, drying air is expanded or narrowly concentrated and blown out over a wide range, so that a wide range of clothing drying and clothing drying time can be reduced. It can also be applied to the use of air conditioners such as humidifiers and air conditioners that blow out.
