Description

Blower

The present invention relates to an air blower, and more specifically, a fan or ceiling fan that is installed on a ceiling, wall, floor, or the like in a living room to reduce the temperature of sensation by direct airflow or circulate indoor air. It is related with the air blower.

Conventionally, as this type of blower, an impeller and a motor are included in a base part serving as a base, and air is blown from the annular blower provided in the upper part of the base part in the horizontal direction with the floor surface. A household blower that generates an air flow is known (see, for example, Patent Document 1).

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

8 is a front view of the blower assembly 100, and FIG. 9 is a cross-sectional view taken along line 9-9 of FIG.

The blower assembly 100 is provided with an annular nozzle 101 having a central opening 102 at the top. An outer casing 118 that supports the annular nozzle 101 at a certain height is provided below the annular nozzle 101. A motor 122 that generates an air flow through the annular nozzle 101 is disposed inside a base 116 located at the top of the outer casing 118 together with a motor housing 126. Further, an impeller (impeller) 130 is connected to a rotating shaft 122 a extending downward from the motor 122, and the diffuser 132 is positioned on the downstream side of the impeller 130. The motor 122 is connected to an electrical connection unit and a power source. Further, the user can operate the blower assembly 100 with a plurality of selection buttons 120 arranged on the outer casing 118.

The blower assembly 100 operates as follows.

The user selects an appropriate one from the plurality of selection buttons 120 and the motor 122 is driven. When the motor 122 is driven, air is drawn into the blower assembly 100 through the air inlet 124 formed in the outer casing 118. Air flows through the inside of the outer casing 118 to the impeller inlet 134 of the impeller 130. The air flow that exits the diffuser outlet 136 of the diffuser 132 and the exhaust portion of the impeller 130 is divided into two air flows that travel in opposite directions through the internal passage 110 of the annular nozzle 101.

The air flow is throttled as it enters the inlet 112 and further throttled at the outlet 114. This throttling creates pressure in the system.

The air flow created in this manner overcomes the pressure generated by the throttle and exits the blower assembly 100 through the outlet 114 as the primary air flow. The primary air flow is concentrated or focused toward the user depending on the arrangement of the guide portion 148. The secondary air flow is caused by entrainment of air from the outside environment, particularly from the area around the outlet 114 and around the outer edge of the annular nozzle 101. This secondary air flow passes through the central opening 102 where there is a total air flow that mixes with the primary air flow and is discharged forward from the blower assembly 100.

JP 2010-077969 A

In such a conventional blower, the front and rear of the central opening 102 need to be opened to allow the secondary air flow to pass therethrough. For this reason, it is necessary to provide the base part for generating a primary airflow in the place away from the ventilation part. However, the base part provided in the distant place has the subject that it cannot act on a secondary air flow positively on the structure, ie, cannot improve ventilation efficiency.

(First embodiment)
First, a schematic configuration of the blower will be described with reference to FIG. FIG. 1 is a perspective view of the air blower according to the first embodiment of the present invention. As shown in FIG. 1, the blower 11 includes a main body 13 having a spherical outer shape. The main body 13 is configured by joining two hollow hemispheres (a first hemisphere 13a and a second hemisphere 13b) with a circular cut surface 29 facing each other. One hemisphere (the first hemisphere 13a) includes six air suction portions 24 that are attraction suction ports, an attraction air blow-off portion 26 that is an attraction air blow-out port, and an annular blow-off port 19; Is provided. An axis passing through the center of the annular air outlet 19 and the center of the spherical main body 13 is defined as a central axis 30 of the blower 11. In other words, the central axis 30 is an axis that is parallel to the direction in which the air flow from the outlet 19 passes and passes through the center of the main body 13.

The air suction part 24 is provided on the surface (outer surface) of the first hemisphere 13 a at a position equidistant from the central axis 30.

A mixing unit 61 is provided between the air suction unit 24 and the attraction air blowing unit 26. The air sucked from the plurality of air suction parts 24 is mixed in the mixing part 61 and blown out from the attracting air blowing part 26. Inside the main body 13, the air suction part 24, the mixing part 61, and the attracting air blowing part 26 are communicated with each other through the second air path. Then, the air sucked into the air suction part 24 and blown out from the induced air blowing part 26 through the mixing part 61, that is, the air passing through the second air passage is defined as air Y, and is indicated by a solid arrow.

A guide surface 14 is provided inside the main body 13, and a suction port 15 is provided near the center of the guide surface 14. Details of the second air passage, the guide surface 14, and the suction port 15 will be described later.

Subsequently, the internal structure of the blower 11 will be described in detail with reference to FIGS. FIG. 2 is a cross-sectional view (first cross-sectional view) taken along a plane perpendicular to the cut surface 29 including the central axis 30 of the blower 11 shown in FIG. 3 is a cross-sectional view (second view) viewed from the outlet 19 side when cut along a plane parallel to the cut surface 29 including the shaft 32 parallel to the cut surface 29 of the blower 11 shown in FIG. FIG.

As shown in FIG. 2, the blower 11 forms an air passage space 12 inside the main body 13. The air passage space 12 is provided at a position facing the induced air blowing portion 26 across a second air passage that communicates the air intake portion 24 that draws the induced air and the induced air blowing portion 26 that blows the induced air. ing. Further, the second air passage and the air passage space 12 are located with a guide surface 14 as one surface of the main body 13 therebetween.

The air passage space 12 includes an impeller 16 provided in communication with the suction port 15 and a high-pressure air generator 18 including a motor 17 for driving the impeller 16. However, the motor 17 is disposed in the main body 13 so as to protrude from the air passage space 12 on the second hemisphere 13b side.

The motor 17 is driven by electric power, that is, electric power is supplied from a power supply unit (not shown) having a control base for controlling voltage and the like, and the impeller 16 is driven. Note that power is drawn into the power supply unit from, for example, a household outlet outside the main body 13.

The blower 11 attracts air by blowing out the air X (indicated by a broken line arrow) sucked from the suction port 15 from the annular air outlet 19 through the air passage space 12 by the high-pressure air generator 18. Details will be described later.

As shown in FIG. 3, the guide surface 14 includes a suction port 15 for taking air into the air passage space 12 in the vicinity of the central axis 30, and has six bottom portions 31 that are substantially rectangular in the circumferential direction from the central axis 30 in a radial manner. Has an extended shape. Further, the vicinity of the central axis 30 on the guide surface 14 has a mountain shape that rises more gently than the surrounding surface. A suction port 15 is provided on the side surface of the mountain shape having the apex at the vicinity of the central axis 30.

The suction port 15 has a plurality of elliptical openings. The opening is arranged so that the long side of the ellipse is parallel to a line extending radially from the central axis 30.

Further, the guide surface 14 has a peripheral wall 22 formed of a double wall of the outer wall 20 and the inner wall 21 extending in the direction away from the surface of the guide surface 14 toward the induced air blowing portion 26 at the outer peripheral end portion. ing. That is, the outer periphery of the first hemisphere 13 a provided with the air outlet 19 side from the guide surface 14 of the outer shell of the main body 13, that is, the air outlet 19 is constituted by the outer wall 20. The space sandwiched between the outer wall 20 and the inner wall 21 constitutes a blowout air passage 23 that communicates with the air passage space 12.

Further, a plurality (six in the case of the present embodiment) of the air suction portions 24 intersect with the circumferential wall 22 and communicate with the suction port 15. In other words, the second air passage that communicates the air suction portion 24 and the attraction air blowing portion 26 penetrates the circumferential wall 22 from the external direction to the internal direction.

The blower outlet 19 is opened in the circumferential wall 22 in a direction away from the surface of the guide surface 14. The air X blown out from the air outlet 19 is a part (air X) of the air (air X + air Y) that has passed through the air suction portion 24, and is sucked from the suction port 15 and is sent in the air passage space 12. The pressure is increased by the impeller 16 and passes through the blowout ventilation path 23. In addition, let the wind path which starts from the suction inlet 15 to the blower outlet 19 through the wind path space 12 and the blowing ventilation path 23 be a 1st wind path. That is, the first air passage is an air passage through which the air X indicated by the broken-line arrow passes.

Further, the air Y attracted by the air blown out from the air outlet 19 is a part of the air (air X + air Y) that has passed through the air suction part 24. The part refers to the air that has passed through the air suction portion 24 and is not sucked from the suction port 15 and is blown out from the attraction air blowing portion 26. The air path through which the air Y passes is the second air path described above.

That is, the air Y attracted to the air X blown out from the air outlet 19 is directly supplied with part of the air X and air Y (air Y) that has passed through the air suction part 24. And by this, ventilation by attraction is performed. Here, the second air passage is provided so as to intersect with the first air passage without crossing the air flow by the through wall 28 penetrating the circumferential wall 22. Further, the attraction air blowing portion 26 is configured by rotating the inner wall 21 around the edge portion thereof. That is, the air outlet 19 is arranged on the outer periphery of the attracting air outlet 26 via the inner wall 21.

The air outlet 19, the impeller 16, the motor 17, the air suction part 24, and the attraction air blowing part 26 are provided so as to be symmetric with respect to the central axis 30, that is, the center of gravity of the main body 13 exists on the central axis 30.

In the above configuration, when the high-pressure air generation unit 18 is operated, the air X is sucked from the air suction unit 24. Part of the sucked air is pressurized in the air passage space 12 from the air inlet 15 and blown out from the air outlet 19 through the air outlet passage 23. That is, it blows out from the blower outlet 19 through a 1st wind path.

When air is blown out from the air outlet 19, air Y (attracted air) is attracted by the air and sucked in from the air suction part 24. Here, a part of the air is sucked in as air X from the suction port 15, but the other air Y is blown out from the attraction air blowing part 26. The air X and the air Y are mixed in the vicinity of the air outlet 19 and are delivered to a distant place as a large air volume.

That is, the structure having the blowout port 19 that blows out air by driving the high-pressure air generating unit on the outer periphery of the induced air blowing unit 26 is an attraction structure.

And in this Embodiment, the suction inlet 15 is provided in the 2nd wind path. According to such a configuration, the air sucked from the suction port 15 by the high-pressure air generation unit 18 passes through the air suction unit 24 at the preceding stage. In other words, the air sucked from the air suction part 24 becomes not only a simple attraction force but also a strong air flow due to the drawing of the high-pressure air generation part 18. Due to this powerful air flow, the air resistance of the air flowing into the air suction portion 24 is reduced. Since the amount of attracting air increases by this, the air blower 11 can produce more blowing airflow efficiently. Since the blown air has a core region formed in the center, it is excellent in straightness, and it can efficiently generate an airflow that reaches far away with little attenuation of wind speed.

Further, since the air sucked from the plurality of air suction portions 24 is once mixed in the mixing portion 61, the variation in the density of the air blown from the attraction air blowing portion 26 is reduced, and smooth air blowing can be achieved.

In addition, since the impeller 16 is in the first air passage and cannot be directly contacted from the outside, it is possible to eliminate the anxiety caused by the contact of the user who uses the blower.

In addition, since the high-pressure air generator 18 can be housed inside the main body 13, a compact configuration can be achieved.

In addition, since there are a plurality of air suction portions 24, even in a use state where one air suction portion 24 is blocked, air can be attracted from other air suction portions 24, so that performance can be exhibited.

In addition, by closing some of the air suction portions 24, the air volume from the air suction portion 24 on the closed side is reduced, and an airflow that is biased toward the unblocked side is blown out from the air suction portion 24. . For this reason, by changing the air suction portion 24 to be closed, it is possible to generate winds with different fluctuations and wind directions.

In addition, the arrangement | positioning position of the air suction part 24 can enlarge the mixing part 61 which is the space which mixes attraction air, if it arrange | positions in the position close | similar to the impeller 16 rather than the blower outlet 19, and mixes the attracted air efficiently. be able to.

(Second Embodiment)
In the second embodiment of the present invention, only differences from the first embodiment of the present invention will be described. FIG. 4 is a perspective view of the blower according to the present embodiment. FIG. 5 is a cross-sectional view of the blower according to the present embodiment.

As shown in FIG. 4, the guide surface 44 of the blower 41 is provided with a suction port 45 for taking air into the air passage space near the center. However, the vicinity of the center of the guide surface 44 provided with the suction port 45 has a protruding shape that rises more rapidly than the surrounding surface. And this protrusion-shaped front-end | tip part protrudes in the direction away from the center of the spherical main body 13 with respect to the plane which comprises the annular blower outlet 19, and the plane which comprises the attraction air blowing part 26. That is, the suction port 45 is provided so as to protrude outward from the air outlet 19 and the attraction air outlet 26. In other words, this configuration is that the suction port 45 is provided farther than the attracting air blowing portion 26 with the central portion of the main body 13 as a reference.

In addition, a mixing unit that mixes the attracted air is provided inside the second air passage and around the portion having the protruding shape of the suction port 45. The mixing unit in the present embodiment mainly mixes the air sucked from the adjacent air suction unit 24.

As shown in FIG. 5, the guide surface 44 is composed of a double wall of the outer wall 20 and the inner wall 21 in the direction away from the surface of the guide surface 44 toward the attracting air blowing portion 26 at the outer peripheral end. A circumferential wall 22 is extended. In other words, the outer periphery of the first hemisphere 13 a provided with the air outlet 19 side from the outer guide surface 44 of the main body 13, that is, the air outlet 19, is constituted by the outer wall 20. The space sandwiched between the outer wall 20 and the inner wall 21 constitutes a blowout air passage 23 that communicates with the air passage space 12.

The suction port 45 includes a plurality of elliptical openings, and the openings are arranged so that the long sides of the ellipse are parallel to a line extending radially from the center of the circle. This is the same as the first embodiment.

Further, an axis passing through the center of the annular air outlet 19 and the center of the spherical main body 13 is defined as a central axis 30 of the blower 41. In other words, the central axis 30 is an axis that is parallel to the direction in which the air flow from the outlet 19 passes and passes through the center of the main body 13.

Subsequently, the operation of the blower 41 will be described with reference to FIG. 5 is a cross-sectional view taken along a plane perpendicular to the cut surface 29, including the central axis 30 of the blower 41 shown in FIG.

As shown in FIG. 5, the air blower 41 forms an air passage space 12 inside a main body 13 composed of a first hemisphere 13a and a second hemisphere 13b. The air passage space 12 is provided at a position facing the air blowing portion 26 across a second air passage that communicates the air intake portion 24 that draws in the air and the air intake portion 26 that blows out the air. Yes. Further, the second air passage and the air passage space 12 are located with a guide surface 44 that is one surface of the main body 13 therebetween.

The air passage space 12 includes an impeller 16 provided in communication with the suction port 45 and a high-pressure air generator 18 including a motor 17 for driving the impeller 16. However, the motor 17 is disposed in the main body 13 so as to protrude from the air passage space 12 on the second hemisphere 13b side.

When the high-pressure air generating unit 18 is operated with the above configuration, air is sucked from the suction port 45 communicating with the air passage space 12. The sucked air is pressurized in the air passage space 12 and blown out from the air outlet 19 through the blowout air passage 23. That is, the sucked air is blown out from the air outlet 19 through the first air passage from the air inlet 45 to the air outlet 19 through the air passage space 12 and the air outlet passage 23.

When air is blown out from the air outlet 19, the air in the vicinity of the induced air outlet 26 is attracted in the same direction as the air blown out from the air outlet 19. By this attraction, the air P indicated by the solid line arrow and the air Q indicated by the broken line arrow are sucked from the air suction part 24 communicating with the second air passage.

Then, by providing the suction port 45 farther than the attracting air blowing part 26 with respect to the central part of the main body 13, a part of the air (air P + air Q) sucked from the air suction part 24 (air Q) is sucked into the air passage space 12 from the suction port 45 immediately after being blown out from the attraction air blowing portion 26. As described above, the air Q sucked into the air passage space 12 passes through the first air passage from the air inlet 45 to the air outlet 19 via the air passage space 12 and the air outlet passage 23, and then the air outlet 19. Is blown out.

Of the air (air P + air Q) sucked from the air suction part 24, the air P is blown from the attraction air blowing part 26 and then mixed with the air P blown from the blower outlet 19 to generate a large air flow. It becomes.

In addition, as described in the first embodiment of the present invention, the annular air outlet 19 is disposed on the outer periphery of the attracting air outlet 26. That is, the suction port 45 exists in the airflow generated by the attraction. And in the air blower 41, the suction inlet 45 protrudes and exists in the downstream rather than the attraction air blowing part 26. FIG. In this configuration, since the air Q is sucked from the suction port 45, the pressure inside the space (the central axis side) of the airflow generated by the attraction becomes lower than the space outside. As a result, the airflow generated by the blower 41 is collected inside (in the direction of the central axis 30). That is, by the said structure, spreading | diffusion of the airflow produced by the air blower 41 is suppressed, and it becomes a spot wind. As a result, the air blower 41 can send a large amount of wind using attraction as far as a strong air current.

(Third embodiment)
In the third embodiment of the present invention, only the points different from the first embodiment and the second embodiment of the present invention will be described. FIG. 6 is a cross-sectional view (first cross-sectional view) taken along a plane perpendicular to the cut surface 29 including the central axis 30 of the blower device 71 according to the present embodiment. FIG. 7 is a cross-sectional view (second cross-sectional view) viewed from the outlet 79 side when cut along a plane parallel to the cut surface 29 including the shaft 91 parallel to the cut surface 29 in FIG.

As shown in FIG. 6, the structure of each air passage (first air passage, second air passage) of the blower 71 is the same as that of the blower in the first embodiment of the present invention, and the first air passage. Reaches the air outlet 19 through the air passage space 12 and the blowout air passage 23 from the suction port 15, and the second air passage communicates the air suction portion 24, the mixing portion 61, and the induced air blowout portion 26. The difference from the air blower in the first embodiment of the present invention is that the first hemisphere 73a and the second hemisphere 73b constituting the main body 13 are not provided with the outlet 19 and the second hemisphere 73b. The internal space 92 includes a battery storage unit 95.

As shown in FIG. 7, the battery storage unit 95 is provided on the outer periphery of the motor 17 having the rotation shaft on the central shaft 30. A plurality of cylindrical cells 94 (12 in FIG. 7) are provided inside the battery storage unit 95, and these are connected by a conductive wire 97 so as to be energized.

The cells 94 are arranged at equal intervals around the center axis 30, that is, the center of gravity of the main body 13 is maintained on the center axis 30. The cell 94 has a hollow inside, and a battery for supplying electric power for driving the high-pressure air generating unit 18 including the impeller 16 and the motor 17 is stored in the hollow. The stored battery may be unchargeable (primary battery) or rechargeable (secondary battery).

A control board 96 having a donut-shaped cross section is provided around the battery storage unit 95. The control board 96 is connected to the battery storage unit 95 and controls power supply from the battery stored in the battery storage unit 95 to the motor 17. Similarly to the cell 94, the control base 96 is also arranged so that the weight distribution is uniform around the center axis 30, that is, the center of gravity of the main body 73 is kept on the center axis 30.

A power receiving unit 98 is provided in the internal space 92 of the second hemisphere 73b and at the position of the pole facing the air outlet 19. The power receiving unit 98 is connected to the control board 96 so as to be energized.

A bottom surface 99 is provided at a position on the outer periphery of the second hemispherical body 73b and facing a plane constituting the air outlet 19. The bottom surface 99 has a circular plane obtained by cutting the spherical surface of the second hemisphere 73b, and a power receiving unit 98 is disposed on the inner space 92 side with the second hemisphere 73b interposed therebetween. That is, by arranging a power supply device (not shown) on the bottom surface 99, power can be supplied to the power receiving unit 98 by non-contact power transmission.

When power is supplied to the power receiving unit 98, power is supplied to the motor 17 and / or each cell 94 via the control board 96. Electric power is supplied to each cell 94 when the battery can be charged, and the determination is made by the control board 96.

When power is supplied to the cell 94, the rechargeable battery stored in the battery storage unit 95 is charged. When there is no power supply device, power is supplied from the battery to the motor 17 via the control board 96.

As described above, the battery storage unit 95 is provided in the present embodiment. For this reason, it becomes possible to carry the blower 71 freely by storing the battery, that is, it is excellent in portability.

Also, a battery storage unit 95 is provided in the internal space 92 of the second hemisphere 73b that does not include the air outlet 79. For this reason, the battery storage part 95 does not press the 1st air path and the 2nd air path, ie, does not reduce the ventilation volume. The first hemisphere 73a is light in weight because most of the first hemisphere 73a is a wall surface. On the other hand, the second hemisphere 73b is heavier because the battery and the motor 17 are provided. The center of gravity of the second hemisphere 73 b is maintained on the central axis 30 by devising the arrangement of the battery storage unit 95 and the control base 96. Further, a bottom surface 99 which is a plane is provided. With these structures, when the main body 73 having a substantially spherical shape is arranged without providing a pedestal, the air outlet 19 always faces upward. In other words, the power supply device and the power reception unit 98 are in a positional relationship in which the planes face each other, and power can be stably and efficiently supplied from the power supply device. Note that not all of the above-described configuration is necessary for the blower outlet 19 to be directed upward, and for example, the battery storage unit 95 may be provided only in the second hemisphere 73b.

There are various types of contactless power transmission such as an electromagnetic induction method and a radio wave method, but the method in this embodiment is not limited.

Although a plurality of embodiments have been described above, the components in the plurality of embodiments may be combined within a consistent range. For example, the configuration including the battery storage unit 95, the control base 96, the power reception unit 98, the bottom surface 99, and the like of FIG.

The blower according to the present invention is installed as a floor, a desk, a ceiling, or a wall in a living room, and is useful as various blower devices used for reducing the temperature of sensation caused by direct airflow or circulating indoor air.
