Description

  The present invention relates to a blower, such as a fan, which is installed in a room or outdoors and used to decrease the perceived temperature due to direct air flow and to circulate air in the room.

  Conventionally, this type of blower includes an impeller and a motor enclosed in a base serving as a pedestal, and air is circulated by blowing air horizontally from the ring-shaped blower provided on the upper portion of the base in the horizontal direction. And the domestic | home-use air blower which produces the flow of air is known (for example, refer patent document 1).

  Hereinafter, the blower will be described with reference to FIGS. 8 and 9.

  FIG. 8 shows a front view of the fan assembly 100, and FIG. 9 shows a cross-sectional view of relevant parts of the fan assembly 100. As shown in FIG. Blower assembly 100 has an annular nozzle 101 defining a central opening 102. Inside the base 116 of the fan assembly 100 is located a blower that produces an air flow through the annular nozzle 101. In the blower, an impeller (impeller) 130 is connected to a rotating shaft extending outward from a motor 122 disposed with a motor housing 126, and a diffuser 132 is positioned downstream of the impeller 130. The motor 122 is connected to an electrical connection and a power supply (not shown), and the user can operate the fan assembly 100 by a plurality of selection buttons 120 shown in FIG.

  With the above configuration, the fan assembly 100 operates as follows.

  When the user selects a desired air volume button from among the plurality of selection buttons 120 and the motor 122 is activated, air is drawn into the fan assembly 100 through the air inlet 124. Air flows through the outer casing 118 to the inlet 134 of the impeller 130. The air flow leaving the outlet 136 of the diffuser 132 and the exhaust of the impeller 130 is split into two air flows which travel in opposite directions through the internal passage 110. The air flow is throttled as it enters port 112 and is further throttled at the outlet 144 of port 112. The throttling causes pressure in the annular nozzle 101.

  The air flow so created overcomes the pressure created by the throttling and exits through outlet 144 as a primary air flow. The primary air flow is directed towards the user in a focused or focused manner by the arrangement of the guide portion 148. The secondary air flow is caused by the suction of air from the external environment, in particular the area around the outlet 144 and the outer edge of the annular nozzle 101. This secondary air flow passes through the central opening 102 where it mixes with the primary air flow to create a total air flow that is expelled forward from the fan assembly 100.

Embodiment 1
First, a blower 11 according to a first embodiment of the present invention will be described with reference to FIGS. 1 is a perspective view of the air blower 11 installed in the room R, FIG. 2 is a right side sectional view of the air blower 11 of FIG. 1, and FIG. 3 is a schematic view seen from the top of the air blower 11 of FIG. FIG.

  The blower 11 blows an air flow toward the inside of the living room R of the house, and as shown in FIG. 1, a plurality of pillars 13 of equal length which are erected from the floor 10 which is one wall of the living room R In the present embodiment, six) are provided. Each pillar 13 has a long strip shape, and a cross section cut in a direction perpendicular to the erecting direction of the pillar is a rectangle formed by short sides and long sides, and the plurality of pillars 13 The upper part of is connected by a top 32. The gaps between the plurality of pillars 13 may be opened at the top without connecting the tops of the pillars 13 by the top plate 32. Further, the pillars 13 penetrate the ceiling surface and project above the ceiling surface. It may be provided as follows.

  Inside the floor 10 (under the floor 40), as shown in FIG. 2, a fan motor 18 constituted by an impeller 16 for generating high pressure air and a motor 17 for driving the impeller 16 is provided There is. As shown in FIGS. 1 and 2, each pillar 13 includes an outlet 19 that blows high-pressure air generated by the fan motor 18 in a direction perpendicular to the direction in which the pillar 13 is erected.

  In the present embodiment, the air outlet 19 is provided on the side surface on the short side of the pillar 13. In addition, a duct 20 for guiding high pressure air generated by the fan motor 18 to the air outlet 19 is provided inside the pillar 13. The ducts 20 are provided in the same number as the pillars 13. A chamber 21 for dividing high pressure air into the duct 20 of each pillar 13 is provided under the floor 40 between the fan motor 18 and the duct 20. The high pressure air generated by the fan motor 18 is introduced into the chamber 21 through the flow path 12 in the floor 40 and is diverted to the ducts 20 by the chamber 21.

  As shown in FIG. 3, the cross section of the pillar 13 in the direction perpendicular to the rising direction of the pillar 13 is vertically elongated in the blowing direction. The plurality of pillars 13 are arranged such that the blowout holes 19 provided on the short sides are in the same plane, and adjacent pillars 13 are spaced apart from each other on the long sides of the pillars 13 It is arranged facing each other.

  This gap forms an induction air path 22 for the air drawn by the air flow blown out from the air outlet 19. In the example of the present embodiment, since six pillars 13 are provided, five induction air paths 22 can be formed in the gaps sandwiched by the pillars 13 smaller than the number of pillars 13.

  Further, in the present embodiment, the cross-sectional shape in the direction perpendicular to the rising direction of the pillars 13 is rectangular, but it may be vertically long in the blowout direction, and may be another shape such as an elliptical shape. Here, the plurality of pillars 13 indicate two or more. Moreover, high pressure air shall mean air more than atmospheric pressure.

  According to the configuration of the blower shown in FIG. 2, when the blower 11 operates, the motor 17 is driven to rotate the impeller 16 to generate high-pressure air, which reaches the chamber 21 through the flow path 12. The high-pressure air is diverted to the plurality of ducts 20 in the chamber 21 and passes through each duct 20 as the internal flow 23, and the wind direction adjusting rib 24 provided in the vicinity of the blowout port 19 The blowing direction is adjusted and blown out from the blowout port 19 to become the blown air flow 25. Then, the air outside the pillars 13 located at the outermost position and the induction air path 22 is attracted by the blowout air flow 25, and becomes an induction air flow 26. The blowoff air flow 25 and the induction air flow 26 are joined downstream of the blowout port of the air blower 11, so that a uniform air flow can be created over a wide area.

  As shown in FIG. 3, the outlets 19 of the pillars 13 are arranged to be in the same plane, and the adjacent pillars 13 have a gap between the side surfaces on the long side of the pillar 13. It arranges so that the side faces of may face each other. According to this configuration, since a pressure difference between the blowout air flow blown out from the blowout port 19 of each pillar 13 and the blowout air flow of the adjacent pillars 13 does not easily occur, a linear stable air flow along the blowout direction is generated. The air flow to be blown out is the surface air flow 50. The surface air flow 50 is an air flow having a substantially uniform wind speed over a wide range, is excellent in straightness, and can reach the far end with little attenuation of the wind speed.

  The (a) front view of the air blower 11 of this Embodiment 1 is shown in FIG. 4, the (b) side view, and the (c) top view are shown. As shown in FIG. 4, in the first embodiment, the side opposite to the side on which the air outlet 19 of the pillar 13 is provided below the vertical center of the pillar 13, that is, the side opposite to the air outlet 19. A shielding means 51 for blocking a part of the induction air path is disposed, and is configured to be movable on the side surface of the pillar 13.

  As an example, FIG. 4 shows a state in which the shielding means 51 is installed below the vertical center of the adjacent pillars 13. According to such a configuration, the air of the induction air path 22 and the air outside the outermost pillar 13 are induced above the vertical center of the adjacent pillars 13, and the induction air flow by the blowout air flow 25 There is an area where 26 occurs. Further, below the center in the vertical direction of the adjacent pillars 13, the shielding means 51 blocks the induction air passage 22, and there is a region where the induction air flow 26 is less likely to occur. That is, when the flow rate of the induced air flow 26 from the induced air path 22 changes in the vertical direction of the pillar 13, the pressure in the induced air path 22 changes. As a result, as shown in FIG. 4 (b), in the area where the induction air flow 26 is not generated, the flow rate of the air blown is larger in the blowout direction front of the blower 11 than in the area where the induction air flow 26 is generated. Since the force in the direction opposite to the direction of the blown air flow 25 works when generating the air flow, the speed of the blown air flow 25 in the region where the induced air flow 26 is generated is reduced. That is, the speed of the blown air flow 25 above the pillars 13 in FIG.

  As a result, as shown in FIGS. 4B and 4C, the blowout air flow 25 above the pillars 13 forward in the blowout direction of the blower 11 merges into the blowout air flow 25 at a high wind velocity below the pillars 13 The combined air flow 52 is directed downward in the vertical direction. On the other hand, in the left-right direction, since the air flow is not generated in the gaps below the plurality of pillars 13 provided with the shielding means 51 by the blown air flow 25, negative pressure is provided.

  On the other hand, the air flow 25 from the top of the pillar 13 having a gap on the left and right attracts air from the gap and straightens the air flow, but the air flow 25 blown out from the outermost pillar 13 has a pressure balance Due to the non-uniformity, the pressure is drawn towards the gap side of the adjacent pillars where the pressure is low. Therefore, the blowout air flow 25 blown out from the outer pillars 13 is attracted toward the center, and the air flow is concentrated into the blowout air flow of the pillar 13 located at the center among the plurality of pillars 13. Therefore, by disposing the shielding means 51 below the vertical center of each pillar 13, the air flow can create an air flow concentrated downward to the vertical direction and to the center in the left-right direction.

  Also, although not shown, when the shielding means 51 is installed above the vertical center of each pillar 13, the air of the induction air path 22 and the outermost part below the center of the adjacent pillar 13 in the vertical direction. There is a region where the air outside the pillars 13 is attracted and the induced air flow 26 is generated by the blown air flow 25. Further, above the center in the vertical direction of the adjacent pillars 13, the shielding means 51 blocks the induction air passage 22, and there is a region where the induction air flow 26 is less likely to occur. That is, when the flow rate of the induced air flow 26 from the induced air path 22 changes in the vertical direction of the pillar 13, the pressure in the induced air path 22 changes. As a result, the flow rate for blowing air increases in the blowout direction ahead of the blower 11 in the area where the induction air flow 26 is not generated, but the direction of the blowout air flow 25 when generating the induction air flow 26 Because the force in the opposite direction works, the velocity of the blown air flow 25 in the area where the induced air flow 26 is generated is slowed. That is, the speed of the blowoff air flow 25 below the pillars 13 becomes slow. As a result, the blowout air flow 25 below the pillar 13 in the blowout direction forward of the blower 11 joins the blowout air flow 25 having a high wind velocity above the pillar 13, and the flow 52 of the merged air is directed upward. On the other hand, in the left-right direction, since the air flow is not generated in the gaps above the plurality of pillars 13 provided with the shielding means 51 by the blown air flow 25, negative pressure is provided. The air flow 25 from the lower part of the pillar 13 having a gap on the left and right attracts air from the gap and brings out the straightness, while the blow air 25 blown out from the outermost pillar 13 has a pressure on the left and right of the pillar 13 Because the balance of the is uneven, blow off as the pressure approaches to the next lower gap side. Therefore, the air flow 25 blown out from the lower side of the outer pillars 13 is attracted to the center, and the air flow is concentrated into the air flow of the pillars 13 positioned at the center among the plurality of pillars 13. Therefore, when the shielding means 51 is installed below the center in the vertical direction of the adjacent pillars 13, the air flow can create an air flow that is concentrated to the upper side in the vertical direction and to the center.

  Therefore, by providing the shielding means 51 as described above, the air blower of the present embodiment has an effect that it is possible to appropriately change the range and direction of the wind according to the user's desire.

  Further, in the present embodiment, the shielding means 51 is configured to close the induction air path 22 above or below the center of the pillar 13 in the vertical direction. It may be possible. FIG. 5 shows a moving means of the shielding means 51. As shown in FIG. As shown in the drawing, for example, it is possible to provide a rail 53 on the surface of the pillar 13 opposite to the blowout direction of the blown air flow so that the user can move the shielding means 51 manually as appropriate. This eliminates the need for a complicated structure to operate the inside of the blower 11, thereby reducing the number of assembly steps and the cost. However, by adopting a mechanism in which the shielding means 51 is operated by a stepping motor or the like, movement and detachment of the shielding means 51 can be automatically performed by the user using a remote control for operating the stepping motor etc. You may As a result, the wind range can be appropriately changed without requiring labor and time for the user.

  The block diagram of the shielding means 51 of this Embodiment is shown in FIG. Further, as shown in FIG. 6, the shielding means 51 of the present embodiment may be provided in the gap between the adjacent pillars 13. With this configuration, the shielding means is not a large plate, but can be configured to close the gap between the pillars 13. Therefore, the shielding means 51 can be miniaturized and the manufacture can be facilitated.

  In the present embodiment, the pillars 13 are erected from the floor 10, and the fan motor 18 that generates high pressure air is provided inside the floor 10 (under the floor), as shown in FIG. The high pressure air generation unit 5 may be configured to be enclosed in the housing 54. As a result, the user can not contact from the outside, so there is no sense of anxiety due to the contact, and cleaning of dust and the like collected near the fan motor 18 becomes easy.

  Further, in the present embodiment, all of the pillars 13 are provided in parallel with the blowing direction, but there is no particular limitation on the direction and the number of the pillars 13. Out of the plurality of pillars 13, the blowout air flow is blown at a wide angle so that the blowout direction of the air is away from the pillars 13 in the central portion toward the pillars 13 provided on the outer side from the pillars arranged in the center. It may be configured. As a result, it is possible to suppress a phenomenon in which the blowout airflows of the pillars 13 positioned at the center among the plurality of pillars 13 are collected, and it is possible to widen the range of the wind.

  Further, in the present embodiment, the number of pillars 13 is six, but there is no particular limitation on their design values. However, the user can appropriately change the width of the blower 11 and the number of the pillars 13 according to the space and the design.
