  The second air passage 25 is provided so as to penetrate the first air passage 21 through the through wall 26, and the first air passage 21 is constituted by the outer wall 15 a, the inner wall 15 b, and the through wall 26, and the second air passage 25 is It is comprised by the inner wall 15b and the penetration wall 26, and the attraction air blower outlet 24 is enclosed by the inner wall 15b which comprises the inner ring of the blower outlet 20. FIG.

  Here, the plurality of attraction air inlets 22 are provided radially from the axial center of the air outlet 20, and are coaxially passing through the spherical center of the housing 12 at a position where the air inlet 16 and the air outlet 20 face each other. It has a built-in configuration. Further, in the present embodiment, the housing 12 is represented by a spherical shape, but the shape of the housing 12 is not particularly limited to this, and the orientation can be freely changed when the housing 12 is placed on the desktop installation table 14. Any shape may be used. For example, it may be a vase, a hemisphere, or an almond. Also, the ring shape is not limited to a circle, and may be a shape formed of a polygon or a curve as long as it is a ring. In addition, there is no problem even if the ring shape is partly interrupted by ribs or the like as long as the performance is not affected. Moreover, according to this invention, the structure which ventilates high pressure air from the suction inlet 16 to the blower outlet 20 by the fan motor 19 without providing the attraction air suction inlet 22 may be sufficient.

  On the other hand, the desktop installation table 14 is configured to be separable from the ball-type fan 13 and is independent of each other.

  As shown in FIG. 1, the tabletop mounting table 14 has a cylindrical outer shape as an example so that the outer surface of the housing 12 can be supported in an annular shape when the ball-type fan 13 is placed and placed. It has a circular support surface 28 on the upper surface of the support portion 27, and a base portion 29 that holds the support portion 27 below the support portion 27. The shape of the support surface 28 is not limited to a circular shape, and may be a polygonal shape or the like as long as it can contact the outer surface of the housing 12 at three or more locations.

  When the support surface 28 has the same curved surface as the outer surface of the housing 12 of the ball-type fan 13 and is configured to come into surface contact, when the support surface 28 is installed at a position overlapping the suction port 16, the support surface 28 opens to the support portion 27. If there is not, the suction port 16 is blocked, so the area of the support surface 28 is preferably as small as possible, and is preferably 20% or less of the suction port 16 area. The support surface 28 may be in line contact with the outer surface of the housing 12 in an annular shape.

  As shown in FIG. 2, the support portion 27 is provided with a rotating shaft 30 that protrudes vertically downward, and the base portion 29 is provided with a bearing 31 for inserting and holding the rotating shaft 30, thereby supporting the base portion 29. 27 is configured to be rotatable.

  As shown in FIG. 1, the support portion 27 has an external opening portion 32 that opens to the outside on the side surface of the support portion 27, and a support surface opening portion 33 that opens to the outside inside the support surface 28. The installation typhoon path 34 is configured so that the opening 32 and the support surface opening 33 communicate with each other. The shape of the external opening 32 and the support surface opening 33 may be a circle, a polygon, or the like, or may be a geometric shape considering the appearance design.

  Further, the opening areas of the external opening 32 and the support surface opening 33 should be made as large as possible so as not to cause pressure loss during ventilation. Desirably, the outer shape of the support surface 28 is the ball type fan 13. If it is larger than the suction port 16, the opening area of the external opening 32 is made equal to or larger than the opening area of the suction port 16, and if the outer shape of the support surface 28 is smaller than the suction port 16 of the ball type fan 13, suction is performed by the support surface 28. It is good that it is 80% or more of the area for closing the mouth 16. Further, the external opening 32 is not limited to one place, and may be provided at a plurality of places.

  A filter 35 that collects dust in the air is fitted in the external opening 32 so as to be detachable by a fitting structure or the like. The filter 35 is made of a nonwoven fabric as an example, and may be added with an action of inactivating the attached allergen and an action of removing mold, fungus, and the like. Further, since the filter 35 is detachable, the maintenance such as periodic cleaning and replacement is easy.

  Further, the height adjusting means 36 (for example, a pole that can be extended and contracted as a slide structure) so that the installation height of the ball type fan 13 mounted on the tabletop installation table 14 can be changed by changing the height position of the support surface 28. Is provided.

  Next, a method of blowing the ball type fan 13 will be described with reference to FIG.

  When a fan motor 19 provided inside the ball-type fan 13 is driven to generate an air flow, the outside air is taken in from the suction port 16 and the pressure is increased by the fan 17, and the air flow that has become high-pressure air is indicated by a solid arrow. Then, the air passes through the first air passage 21 and is blown from the outlet 20. At this time, since the inside of the annular air outlet 20 has a negative pressure, as indicated by the dotted arrow, outside air is attracted from the attracting air suction port 22, and the attracted air is attracted by passing through the second air passage 25. Air is blown from the air outlet 24.

  At this time, the air attracted from the plurality of attracting air inlets 22 is mixed by the attracting air mixing unit 23 provided in the second air passage 25 and attracted in a state where the flow is changed in the direction of the attracting air outlet 24. Since the air is blown out from the air outlet 24 in a bundled state, the blown air forms a core region at the center, and thus has excellent straightness and can efficiently generate an airflow that reaches far away with little attenuation of the wind speed. it can. Here, high-pressure air refers to air at atmospheric pressure or higher.

  As the position of the attraction air suction port 22, it is preferable to arrange it at a position closer to the fan 17 than the air outlet 20, because the attraction air mixing unit 23 can be enlarged and the attracted air can be efficiently gathered. The air can be attracted more efficiently if the total cross-sectional area of the plurality of air intake ports 22 is equal to or larger than the cross-sectional area of the air inlet 24. Therefore, it is preferable.

  Although not shown, when the ball type fan 13 is placed on the tabletop mounting table 14 at an angle, for example, the suction port 16 or the attraction air suction port 22 of the ball type fan 13 overlaps the support surface 28 of the tabletop mounting table 14. If this is not the case, as described above, the outside air is directly sucked into the suction port 16 and the attraction air suction port 22 and then blown.

  On the other hand, when part or all of the suction port 16 or the attraction air suction port 22 of the ball-type fan 13 overlaps with the support surface 28 of the tabletop installation table 14, outside air is first taken in from the external opening 32 provided in the support unit 27. Then, after passing through the installation typhoon channel 34 and flowing into the support surface opening 33, the suction port 16 or the attracting air suction port 22 is sucked. Further, the intake air is purified by a filter 35 provided in the installation typhoon passage 34.

  FIGS. 3A, 3B and 3C show how the air direction of the blower 11 of the present invention realized by the above configuration is changed.

  As shown in FIGS. 3A, 3 </ b> B, and 3 </ b> C, since the ball-type fan 13 and the desktop installation table 14 can be separated, the user places the ball-type fan 13 on the desktop installation table 14. Since the wind direction can be freely changed depending on the angle and angle, the apparatus can be made compact without requiring a complicated wind direction changing mechanism. In addition, when changing the wind direction, the range of change becomes as wide as possible, that is, the degree of freedom is high, so that an effect of good usability can be obtained.

  As shown in FIG. 3 (a), when the ball-type fan 13 is installed on the table-top installation table 14, it can be installed so that the air outlet 20 faces upward, and when the user does not want to hit the wind directly, This is effective when you want to stir the air in your room.

  Further, as shown in FIG. 3B, when the ball-type fan 13 is installed on the table-top installation table 14, it can be installed so that the air outlet 20 faces in the horizontal direction, and the user wants to hit the wind directly. It is effective at times.

  Further, as shown in FIG. 3 (c), when the ball-type fan 13 is installed on the table-top installation table 14, it can be installed so that the air outlet 20 faces downward, and the object is blown down by the wind. It can be used like a cold.

  Here, even if the ball-type fan 13 and the desktop mounting table 14 are connected by a binding means such as a rope or a chain, for example, the position of the ball-type fan 13 on the table-top mounting table 14 and the angle of the binding means can be changed. There is no particular problem as long as the length is sufficiently secured and the wind direction can be changed.

  Further, as a further effect, even if a part or all of the suction port 16 or the attraction air suction port 22 overlaps with the support surface 28 of the tabletop installation table 14, the external opening 32, the installation table wind path 34, Since the support surface opening 33 is provided, the air blowing performance can be maintained regardless of how the ball-type fan 13 is placed on the desktop installation table 14.

  Furthermore, since the support portion 27 of the tabletop installation table 14 is rotatable in a substantially horizontal direction, the user can change the wind direction while the ball-type fan 13 is placed on the tabletop installation table 14, thereby improving usability. The effect that it can be made is acquired.

  Here, it is also possible to incorporate a drive motor in the support portion 27 or the base portion 29 so that the ball-type fan 13 can automatically rotate and swing.

  In addition, the height of the support portion 27 can be changed by changing the height of the support portion 27 by means of a telescopic pole using a slide mechanism as the height adjusting means 36. Thereby, not only the up / down / left / right wind direction can be changed, but also the wind blowing height can be changed, so that the variation of the air flow can be increased and the usability can be further improved.

  Further, when the filter 35 is provided in the external opening 32, when a part or all of the suction port 16 or the attraction air suction port 22 of the ball type fan 13 overlaps with the support surface 28 of the tabletop installation table 14, the external opening By purifying the outside air taken in from 32 by the filter 35, it is possible to suppress the adhesion of dirt to the fan motor 19 and to provide the blower device 11 in which the blower performance is not easily lowered.

  Since the filter 35 may be installed in the path from the outside to the suction port 16, the same effect can be obtained even if the filter 35 is provided in the installation typhoon path 34 or the support surface opening 33.

  According to the present invention, the position of the external opening 32 is not limited to the side surface, and the function and effect are not changed regardless of the location where the external opening 32 is open to the outside.

  In the present embodiment, the base 29 is indispensable for rotation and height adjustment. However, even if only the support 27 is provided without the base 29, the position and angle at which the ball-type fan is placed on the tabletop mounting table. Therefore, it is possible to freely change the wind direction freely up and down, left and right, so that the air blower can be made compact without providing a complicated mechanism for changing the wind direction, and an air blower that is easy to use can be provided.

  When the suction port 16 is sufficiently larger than the support surface 28 provided in the support portion 27, as an example, if the area of the suction port 16 is five times or more than the area of the support surface 28, the support portion 27 has an external opening portion. 32, the support surface opening 33, and the installation typhoon passage 34 are not provided with any problem because the influence on the air blowing performance is sufficiently small.

(Embodiment 2)
In the second embodiment, the same components as those in the first embodiment are denoted by the same reference numerals, and detailed description thereof is omitted.

  Moreover, since the air blower 11 of Embodiment 2 of this invention shown in FIG. 4 is another form of the desktop installation base 14 of Embodiment 1, the structure of the ball-type fan 13 is the same as that of Embodiment 1. FIG. A description of the ball type fan 13 is omitted.

  As shown in FIG. 4, the cylindrical support portion 27 has a support surface 28 and a support surface opening 33 on the upper surface, an external opening 32 on the lower surface, and does not block the external opening 32. Three mounting legs 37 are provided in the vicinity of the outer periphery of the support portion 27. The table-top installation table 14 includes a support portion 27 and attachment feet 37. The installation typhoon path 34 of the support portion 27 is a path from the lower external opening portion 32 toward the upper support surface opening portion 33. A filter 35 (not shown) is installed in the external opening 32.
