  In the blower, the air blown out from the air outlet (annular nozzle) provided in the collar portion of the circular opening of the main body having a spherical shape, and the vicinity of the center of the circular opening (attracted air outlet) induced by the air ) It is said that it is possible to efficiently generate an air current with less wind speed attenuation by attracting air that blows out more.

JP 2013-224650 A

  In such a conventional blower, since the main body has a spherical shape, the main body is rotated to change the direction of the wind. However, at this time, the position of the operation unit is difficult to understand and the operability is lowered. There is a case.

  Then, this invention aims at improving operativity, ensuring the sufficient air path required for ventilation.

  In order to achieve the above-described object, a blower according to the present invention is provided with a predetermined interval on one pole, an opening provided to include the one pole, and an outer peripheral surface of the one pole, and each of them has induced air. A plurality of attracting air suction ports for suction, the other pole facing the one pole, a substantially spherical main body comprising an air suction port for sucking air, and an inner space of the main body, the attraction air suction port and the opening A first air passage member that communicates with the inside of the wall surface and communicates the suction port and the opening portion with an air passage constituted by the outside of the wall surface and the inner surface of the main body, and is provided in the internal space of the main body. A second air passage that communicates with the first air passage member, and that communicates the space for placement with the air suction port. Arranged in the space for arrangement in the member and the main body A pressure air generator, and in the main body, the other pole side of the attraction air suction port is provided with an operation unit for instructing the operation of the high pressure air generator. It achieves its purpose.

  According to the air blower according to the present invention, since the operation unit for instructing the operation of the high-pressure air generator is provided on the other pole side of the attraction air suction port in the main body, the substantially spherical main body is appropriately rotated. Even when the direction of the wind from the opening is changed, the operation unit can be easily confirmed, and a decrease in operability can be suppressed.

  In other words, since the attracting air inlet port portion is in a state where the outer peripheral surface portion of the spherical surface is deleted from the outer peripheral surface of the main body, if the operating portion is provided on the other pole side, this deleted surface exists. As a result, it is easy to check the state of the operation unit from the user side on the leeward side (upper extension line of the opening), thereby suppressing a decrease in operability.

  The blower according to the present invention includes one pole, an opening provided to include the one pole, an attracting air suction port for sucking inductive air, the other pole facing the one pole, and an air suction port for sucking air A substantially spherical main body, and an inner space of the main body, the induction air inlet and the opening communicate with each other inside the wall, and the inlet and the opening are configured by the outside of the wall and the inner surface of the main body. A first air passage member that communicates with the air passage, and an internal space of the main body, and an arrangement space for disposing the high-pressure air generator in communication with the air passage is configured between the first air passage member, A second air passage member communicating the arrangement space and the air suction port. Moreover, the space for arrangement | positioning in a main body is equipped with a high pressure air generator. And in the main body, the operation part which instruct | indicates the driving | operation of a high pressure air generator is provided in the other pole side of the attraction air suction port. Accordingly, even when the main body of the substantially spherical body is appropriately rotated and the direction of the wind from the opening is changed, the operation unit can be easily confirmed, and deterioration in operability can be suppressed.

  In other words, the attracting air suction port portion is in a state in which the outer peripheral surface portion of the spherical surface is deleted from the outer peripheral surface of the substantially spherical body, so if the operating portion is provided on the other pole side, this outer peripheral surface is As a result of not being present, it is easy to confirm the state of the operation unit from the user side on the leeward side (above the extension line of the opening), thereby suppressing a decrease in operability. Further, in the main body, if an operation unit for instructing operation of the high-pressure air generator is provided on the other pole side of the attraction air suction port, for example, the control unit connected to the operation unit is a main body facing the operation unit. Since it is provided inside, it is possible to suppress the deterioration of the air blowing characteristics.

  That is, in the main body, the portion between the plurality of air intake ports is a portion where the air passage from the high-pressure air generator is provided. It is possible to suppress the deterioration of the air blowing characteristics.

  Moreover, it is good also as a structure provided with the display part which displays the driving | running state of a high pressure air generator in the other pole side of an operation part.

  Thereby, when operating an operation part, the present driving situation can be grasped immediately and operation based on the grasped driving situation can be performed.

  Moreover, it is good also as a structure provided with the branch air path used as the passage of the high pressure branch air branched from the high pressure air which a high pressure air generation apparatus produces | generates between an attraction air suction inlet and an operation part.

  Thereby, since the blowing wind in which the turning component is suppressed is blown out from the opening, a user at a long distance can also obtain a sufficient refreshing feeling.

(Embodiment 1)
Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings for understanding of the present invention. The following embodiment is an example embodying the present invention, and is not intended to limit the technical scope of the present invention. Moreover, the same number is attached | subjected about the same site | part through all the drawings. Furthermore, in each drawing, the description of the details of each part not directly related to the present invention is omitted.

  Hereinafter, the air blower according to Embodiment 1 of the present invention will be described.

  FIG. 1 is an external view of an air blower according to Embodiment 1 of the present invention.

  As shown in FIG. 1, the blower 1 has a substantially spherical shape, and has a central axis 2 that virtually penetrates the center of the spherical body as an axis center.

  The central axis 2 is in point contact with a spherical air blowing side pole 3 (corresponding to one pole) and a suction side pole 4 (corresponding to the other pole) facing the air blowing side pole 3. In addition, the substantially spherical shape here means that a sphere is formed at a glance, and is an expression that takes into consideration that a part of the surface of the sphere does not become a true sphere due to unevenness on the surface of the sphere due to an opening or the like described later. That is, even if it does not become a true sphere, it is included in a substantially spherical shape when it forms a sphere at first glance.

  In addition, the blower 1 includes a substantially hemispherical first frame 6 with a cut surface 5 perpendicular to the central axis 2 at a position equidistant from the spherical poles (the blower side pole 3 and the suction side pole 4). The second frame 7 is also divided into two equal parts.

  The first frame 6 includes the blower-side electrode 3 and has a hollow shape, that is, a hemispherical structure. The first frame 6 is provided with a circular opening 9 formed in a plane perpendicular to the central axis 2 in the vicinity of the blower side pole 3. Note that the term “neighborhood” as used herein is an expression based on the fact that the blower side pole 3 is on the circumference of the sphere and therefore does not coincide with the plane to which the opening 9 belongs. Therefore, the expression that the opening 9 includes the blower-side electrode 3 can be used. Furthermore, the first frame 6 includes a plurality of (six in the first embodiment) induction air inlets 8 provided at equal intervals in the circumferential direction of the central shaft 2 with the blower-side electrode 3 as the center.

  The attraction air suction port 8 has a circular shape with the same diameter, and the center of each circle is located on the same circumference around the central axis 2 (on the same cross section perpendicular to the central axis 2). However, it is not in contact with the adjacent attraction air inlet 8, that is, independent of each other, thereby securing a plurality of air passages to be described later in the internal space.

  The opening 9 includes an induced air blowout port 10 communicating with the induced air suction port 8 in the interior thereof, which will be described in detail later.

  The second frame 7 includes the suction side pole 4 and has a hollow shape, that is, a hemispherical structure. The second frame 7 includes an air suction port described later around the suction side electrode 4.

  FIG. 2 is an exploded side view of the air blower according to Embodiment 1 of the present invention.

  As shown in FIG. 2, the blower 1 includes a first air passage member 204, an arrangement space in a hollow space (inside) of a substantially spherical main body composed of the first frame 6 and the second frame 7. 216 and the second air passage member 212 are arranged in this order from the first frame 6, and this configuration constitutes a blower casing. Further, by providing the high-pressure air generator 211 in the arrangement space 216, it functions as a blower.

  The first air passage member 204 is a lower portion that forms a hollow internal space between the upper member 202 having the induced air outlet 10 having a circular cross section perpendicular to the central axis 2 and the upper member 202. It is formed with the member 203. In addition, a plurality of support portions 213 (six in the first embodiment) project from the outer wall surface of the lower member 203 in parallel with the central axis 2 toward the suction side pole 4. Here, the term “projection” means that the projection is provided in a protruding state.

  The second air passage member 212 is provided with a plurality of contact portions 214 (the same number as the support portions, six in the present embodiment) corresponding to the plurality of support portions 213. Further, the abutting portion 214 is provided so as to protrude in parallel with the central axis 2 toward the air blowing side pole 3 of the second air passage member 212. An arrangement space 216 is formed between the first air passage member 204 and the second air passage member 212 by the front end portion of the support portion 213 and the front end portion of the contact portion 214 coming into contact with each other. The term “contact” as used herein refers to contact in a contact state. Further, the second air passage member 212 is provided with a cylindrical engaging portion 215 projecting from the central axis 2 in parallel with the central axis 2 toward the suction side pole 4.

  In the second frame 7, air suction ports 201 are provided as a number of punching holes in the vicinity of the suction side electrode 4. External air is sucked into the substantially spherical main body through the air suction port 201, and details of the mechanism will be described later.

  The high-pressure air generator 211 includes a motor 206, a base cover 207, a base 208, a motor cover 209, and a blade 210. The high-pressure air generator 211 is fixed to the first air passage member 204 and fixed to the fixing portion 205 made of an elastic body made of rubber. The air channel member 204 is fixed to the outer wall side.

  Then, the flow of the air in the air blower 1 is demonstrated using FIG.3 and FIG.4. 3 is configured by arranging the first frame 6, the first air passage member 204, the high-pressure air generator 211, the second air passage member 212, and the second frame 7 shown in FIG. 2 in this order. It is sectional drawing at the time of cut | disconnecting the air blower 1 by the plane containing the central axis 2 (an example). FIG. 4 is a top view of the first frame 6 and the first air path member 204 as viewed from the air blowing side pole 3 side. The structure of each member and the details of the attachment procedure will be described later separately.

  In FIG. 3, a motor 206 is disposed in the vicinity of the center 301 of a sphere that is equidistant from the blower side pole 3 and the suction side pole 4, and the rotation of the motor 206 is rotated by rotating the rotation axis of the motor 206. A blade 210 connected to the shaft rotates about the central shaft 2. The power source of the motor 206 corresponds to electricity supplied from a lead wire (not shown) drawn from the outside of the main body, electricity obtained from a built-in battery, or the like.

  When the blades 210 rotate, air from the outside of the main body is sucked from the air suction port 201 (see the air blowing path 303). The sucked air passes through the opening on the air suction port 201 side (the air suction port side opening 302) of the second air passage member 212 having a function as an orifice, and the inside of the blade 210 in the arrangement space 216 It flows into (central part). The air that has flowed in is discharged from the central axis 2 in the direction of the outer periphery based on the air blowing structure of the blades 210, that is, pushed out in the outer circumferential direction of the arrangement space 216 that also functions as the air blowing path.

  The pushed-out air is guided to the opening 9 through the air passage 304 formed by the outer wall (outside the wall surface) of the first air passage member 204 and the inner wall of the first frame 6 by the pressing. Here, as shown in FIG. 4, the opening 9 has a circular shape centered on the air blowing side pole 3, and the induced air outlet 10 provided in the first air passage member 204 and the center thereof. It is configured identically. Moreover, the plane which comprises the attraction air blower outlet 10 and the plane which comprises the opening part 9 comprise the substantially same plane. Here, “substantially the same plane” means that the plane that forms the opening 9 is an error of, for example, several millimeters from the center 301 of the sphere compared to the plane that forms the induced air outlet 10, and is far away or close. Is included. The diameter of the opening 9 is designed to be larger than the diameter of the induced air outlet 10, and the space between the opening 9 and the outer wall of the induced air outlet 10 is a circle that communicates with the air passage 304. An annular air outlet 401 is configured. As a result, the air sucked from the air suction port 201 is blown out as an annular air flow in the direction parallel to the central axis 2 and away from the center 301 by the action of the blades 210.

  The annular airflow blown out from the air outlet 401 attracts the air inside the annular, that is, the air in the vicinity of the attractive air outlet 10 in the same direction due to the attraction effect. At this time, air is attracted from a plurality of attraction air inlets 8 communicating with the attraction air outlet 10 (see the air flow path 306), mixed in the attraction air mixing unit 305, and sequentially sent to the attraction air outlet 10. .

  The annular airflow and the induced air described above are combined in the vicinity of the opening 9 and are discharged from the direction of the central axis 2 as a spot wind with little divergence.

  The above is the outline of the configuration and operation of the blower device 1 according to the first embodiment.

  Subsequently, the detailed structure of the first air passage member 204 according to the first embodiment will be described with reference to FIG. FIG. 5 is a detailed explanatory view of the first air passage member according to the first embodiment.

  As described above, the first air passage member 204 includes the upper member 202 and the lower member 203, and includes the induced air mixing unit 305 indicated by a broken line between the two members. Further, the first air passage member 204 includes a plurality of induction passage inner wall portions 501 (six in the first embodiment) having a center on the circumference around the central axis 2. The attraction air mixing unit 305 communicates with the attraction air suction port 8 provided in the first frame 6 through an attraction passage inner wall portion 501 constituted by an annular inner surface. Further, the attraction air mixing unit 305 communicates with the attraction air outlet 10.

  Subsequently, the details of the first frame 6 and the first air passage member 204 according to the first embodiment will be described with reference to FIGS. 6A and 6B, and the first frame and the first air passage member are also described. The locking procedure will also be described. FIG. 6 is a detailed explanatory view of the first frame 6 and the first air passage member via the first passage inner wall portion 501 according to the first embodiment.

  FIG. 6A shows the first frame 6 as viewed from the center of the sphere. As shown in FIG. 6A, the first frame 6 includes a plurality of first protrusions 601 toward the central axis 2 on the inner periphery of an annular cut surface (first frame 6 side cut surface 605). ing. A total of six first protrusions 601 are arranged at equal intervals, one at each intermediate position of the attracting air suction port 8 arranged at equal intervals on the circumference. Further, an arbitrary one of the plurality of first protrusions 601 is provided with a screw hole 602.

  FIG. 6B shows the first air channel member 204 corresponding to the first frame 6 in FIG. 6A from the center of the sphere at the position indicated by the broken line arrow 603 in FIG. It is a figure at the time of pushing in, and is a corresponding | compatible figure of a 1st flame | frame and a 1st air path member. By arranging in this way, there is a space between the entire inner surface of the first frame 6 and the outside of the wall surface of the first air passage member 204 (outside of the walls constituting the induction air mixing portion 305 and the induction passage inner wall portion 302). And the space forms the air passage 304. In addition, pushing into the position shown by the broken-line arrow 603 means that the corresponding induction passage inner wall portions 302 are arranged so that their circular shapes coincide with each other. And each induction air suction inlet 8 and the induction channel | path inner wall part 302 which has an annular shape comprise the circle | round | yen which has the same diameter, and each circular edge part is formed thinly so that fitting is possible. Yes. Here, the term “fitting” refers to fitting objects having shapes matched to each other.

  By pressing the corresponding attracting passage inner wall portions 302 against the respective attracting air suction ports 8, the thin surfaces are closely joined to each other. Thereby, the spatial independence of the air flow path 304 comprised between the 1st flame | frame 6 and the 1st air path member 204 and the internal space of the 1st air path member 204 which is an attraction air path is maintained, and air Leakage can be prevented. However, in this state, the first frame 6 and the first air path member 204 are not yet pressure-bonded. Therefore, although they are spatially independent, they have not reliably prevented air leakage.

  The above is the locking procedure between the first frame 6 and the first air passage member 204 according to the first embodiment. With this locking, the hemisphere 604 on the blowing side pole 3 side is completed. Further, the motor 206 is fixed to the fixing portion 205 of the hemisphere 604 by an elastic member, and the base cover 207, the base 208, the motor cover 209, and the blades 210 are sequentially attached toward the suction side pole 4 direction. Screwed to the end of the rotation shaft of the motor 206. That is, the high-pressure air generator 211 is attached to the first air path member 204.

  Subsequently, the details of the second air passage member 212 according to the first embodiment will be described with reference to FIGS. 7, 8, and 9, and the locking procedure between the hemisphere and the second air passage member will be described. Also explained. 7 is a detailed explanatory view of the second air passage member according to the first embodiment of the present invention, and FIG. 8 is a hemisphere of the blowing side pole and the second air passage member according to the first embodiment of the present invention. FIG. 9 is an explanatory view showing before and after locking of the hemisphere and the second air passage member according to Embodiment 1 of the present invention. Further, FIG. 7A is a view of the second air passage member 212 as viewed from the sphere center direction, and FIG. 7B is a view of the second air passage member as viewed from the suction side pole direction.

  As shown in FIG. 7A, the second air passage member 212 includes a plurality of first protrusions 601 provided on the first frame 6 that are guided in the center direction of the sphere in parallel with the central axis 2. The first guide portion 701 (same number as the first protrusions 601 in the first embodiment) is provided. In addition, a plurality of first locking portions 702 for preventing the first protrusion 601 provided on the first frame 6 from moving toward the blowing side pole 3 side are provided in the vicinity of the first guide portion 701 (this embodiment). 1, the same number of first protrusions 601 as 6). In addition, the screw hole 705 is provided in the position corresponding to the screw hole 602 of the 1st flame | frame 6 mentioned above among the some 1st latching | locking parts 702. FIG. Further, a plurality of second guide portions 703 and a plurality of second locking portions 704 are provided (six in each case in the first embodiment). The second guide portions 703 and the second locking portions 704 will be described later. To do. The second air passage member 212 further includes a circular air inlet 201 side opening (air inlet side opening 706) centered on the central axis 2.

  Further, as shown in FIG. 7B, on the second frame 7 side of the second air passage member 212, on the outer periphery of the air suction port side opening 706, concentrically with the air suction port side opening 706. A circular second engaging portion 707 is provided. The second engaging portion 707 has a cylindrical shape centered on the central axis 2 and has a shape protruding in the direction of the suction side pole 4 (convex shape).

  As shown in FIG. 8, when the second air passage member 212 shown in FIG. 7 is locked to the hemisphere 604 to which the high-pressure air generator 211 is fixed, first, the air of the second air passage member 212 is The cut surface opposite to the suction port side opening 706 is made to face the cut surface of the hemisphere 604 (first frame side cut surface 605). Subsequently, the six corresponding support portions 213 and the contact portions 214 are arranged at positions facing each other (see a broken line 801 in FIG. 8). At this time, the screw hole 602 provided in the first frame 6 and the screw hole 705 provided in the second air passage member 212 are opposed to each other. FIGS. 9A and 9B are enlarged views of the point portion 802 in FIG. 8 when placed and brought close to each other as described above. In FIG. 8, the rotation direction of the blade 210 is counterclockwise when viewed from the direction of the suction side pole 4 as indicated by an arrow 803.

  FIG. 9A is a diagram before screwing, and FIG. 9B is a diagram after screwing, which will be described in detail. As shown in FIG. 9A, before screwing, the first protrusion 601 is slid along the inner wall of the first guide portion 701 in the direction of the second air passage member 212 (arrow 903 direction). Here, sliding means moving in a contact state. By the sliding, the first protrusion 601 passes through the first guide part 702 to the suction side pole 4 side (downward in FIG. 9A), and the vertical relationship in the direction parallel to the central axis is reversed. In this state, the support portion 213 and the contact portion 214 are in contact with each other at a cross section substantially perpendicular to the central axis 2 (broken line portion 902). At this time, about 50% of the cross-sectional areas of the support part 213 and the contact part 214 are brought into contact with each other.

  Here, the cross section 904 of the support portion 213 is inclined with respect to the cross section perpendicular to the central axis 2. The direction of the inclination is a direction in which the facing contact portion 214 is pushed out in the direction of the suction side pole 4 during the rotation at the time of screwing (arrow 905). The rotation direction at the time of screwing is a direction in which the second air passage member 212 is rotated in the reverse direction with respect to the rotation direction of the blades 210.

  The cross section 906 of the contact portion 214 is also inclined with respect to the cross section perpendicular to the central axis 2. The direction of the inclination is a direction in which the opposing support portion 213 is pushed out in the direction of the air blowing side pole 3 during the rotation at the time of screwing (arrow 905). With this configuration, as shown in FIG. 9B after screwing, after screwing, the support portion 213 and the abutting portion 214 are screwed to each other (the direction in which both poles are directed toward the sphere center) due to the inclination. Produces a force in the opposite direction (arrow 907).

  As described above, the first air path member 204 is brought into contact with the first frame 6 and the second air path member 212 as a result of pressing the support portion and the abutting portion in a direction repelling each other during screwing. Can be pressed and pressed against the second frame 7 (here, the description of the joining of the second frame 7 has not yet been made, but when the first frame 6 and the second frame 7 are joined, the second air path member 212 is pressed to the second frame 7 side). Thereby, the airtightness of the air flow path constituted by the first airflow path member 204 and the first frame 6 can be improved, and at the same time, the airtightness of the induced airflow path from the induced air inlet 8 to the induced air outlet 10 This also improves the performance and prevents the mutual airflows from interfering with each other. Moreover, although the confidentiality of the ventilation path which connects the 2nd air path member 212 and the 2nd flame | frame 7 can also be improved similarly, this structure is mentioned later.

  Further, when the high-pressure air generator 211 is configured to be fixed to the first air passage member 204, the screwing rotation direction (rotational direction in the circumferential direction) is the rotation of the blades 210 constituting the high-pressure air generator 211. The second air passage member 212 is rotated in the opposite direction with respect to the direction.

  In this configuration, the force applied to the first frame 6, the first air passage member 204, and the second air passage member 212 due to the rotation of the blades 210 is in the direction in which the pressure due to screwing increases, so even for long-term use. Looseness of each part can be prevented, that is, deterioration of airtightness can be prevented.

  Next, the first protrusion 601 whose vertical relationship is reversed as described above will be described. The contact surface 908 that contacts the contact surface 909 of the first locking portion 702 is inclined with respect to a cross section perpendicular to the central axis 2. The direction of the inclination is a direction in which the corresponding first locking portion 702 is pulled in the direction of the blower side pole 3 during the rotation at the time of screwing (arrow 910). The contact surface 909 of the first locking portion 702 is also inclined with respect to the cross section perpendicular to the central axis 2. The direction of this inclination is the direction in which the corresponding first protrusion 601 is pulled in the direction of the suction side pole 4 during the rotation at the time of screwing (arrow 910). With this configuration, as shown in FIG. 9B after screwing, after the screwing, the first locking portion 702 and the first protrusion 601 are pressure-bonded to each other by the inclination.

  As described above, the first frame 6 and the second air passage member 212 are pressure-bonded as a result by bringing the contact surfaces of the first locking portion 702 and the first protrusion 601 into pressure contact with each other during screwing. The Further, since the support portion and the contact portion are in contact with each other, as a result, the first air path member 204 is pressed and pressed against the first frame 6.

  The procedure for screwing the second air path member 212 to the hemispherical body 604 has been described above. After the screwing, the screw hole 602 and the screw hole 705 are arranged to form a concentric circle. Screw into the hole 602 from the second air passage member 212 side (arrow 912 in FIG. 9B). This screwing is intended to prevent the movement (displacement) of the second air passage member 212 and the first frame 6 in the circumferential direction. Therefore, regardless of the number of screws to be used, it is possible to always apply pressure uniformly from the second air passage member 212 to the first frame 6 side. In other words, the air density of the air passage is reduced due to the looseness of the screws, and no air leakage occurs as a result.

  The above is the locking procedure of the first frame 6, the first air passage member 204, and the second air passage member 212 according to the first embodiment. For convenience of explanation, a substantially spherical body composed of the first frame 6, the first air path member 204, and the second air path member 212 is hereinafter referred to as a substantially spherical body A.

  Subsequently, the details of the second frame 7 according to the first embodiment will be described with reference to FIGS. 10 and 11, and the locking procedure between the second air passage member 212 and the second frame 7 will also be described. To do. FIG. 10 is a detailed explanatory view of the second frame according to Embodiment 1 of the present invention, and FIG. 11A is an explanatory view of the engagement between the substantially spherical body A and the second frame.

  FIG. 10 shows the shape of the second frame 7 as viewed from the center of the sphere, and a plurality of second protrusions 1001 are provided on the inner periphery of the annular second frame-side cut surface 1004 toward the central axis 2. ing. A plurality (six in the first embodiment) of second protrusions 1001 are arranged at equal intervals on the circumference. In addition, a first engagement portion 1002 having a circular shape centered on the central axis 2 is provided on the outer peripheral portion of the air suction port 201 formed of a plurality of through holes. The first engaging portion 1002 has a concave shape, that is, the second engaging portion 707 having the same cylindrical shape provided in the second air passage member 212 is sandwiched between the inner periphery and the outer periphery of the concave shape. Are arranged as possible. Further, a screw hole 1003 for screwing with the second air passage member 212 is provided. Here, “engagement” refers to engaging and matching, and here, the concave-convex shape means combining the concave and convex portions.

  As shown in FIG. 11A, when the second frame 7 shown in FIG. 10 is locked to the substantially spherical body A, first, the first frame side cut surface 605 and the second frame side cut surface 1004 are set. Place them facing each other.

  Subsequently, the six second protrusions 1001 are opposed to the six second guide portions 703 provided on the second air passage member 212, respectively, and are slid along the guide direction (guide line 1103). Specifically, the guide direction is a direction parallel to the central axis and causing the suction side electrode 4 to be close to the blower side electrode 3. In addition, the left figure of Fig.11 (a) is the schematic for demonstrating the positional relationship of the 2nd guide part 703 and the 2nd protrusion 1001. FIG.

  When the second protrusion 1001 is slid in the guide direction, the sliding of the second protrusion 1001 stops at a guide end point, that is, at a position 1004 where the second frame side cutting surface 1004 contacts the first frame side cutting surface 605. . When the first frame 6 or the second frame 7 is rotated in the screwing direction 1105 in this state, the second protrusion 1001 is hooked on the second locking portion 704 as shown in FIG. The The term “hanging” refers to hooking and stopping.

  Here, each of the second protrusion 1001 and the second locking portion 704 is inclined with respect to a cross section perpendicular to the central axis 2 at the contact surface. The direction of this inclination is a direction (arrow 1106) which pulls the corresponding 2nd latching | locking part 704 to the suction side pole 4 in the case of the rotation at the time of screwing (screwing direction 1105). With this configuration, as shown on the right side of FIG. 11B after screwing, after screwing, the second protrusion 1001 and the second locking portion 704 are pressed against each other by the inclination, that is, the second frame. 7 and the second air passage member 212 are pressure-bonded. Naturally, since the second air passage member 212 is pressure-bonded to the first frame 6 by the above-described configuration, as a result, the second frame 7 and the first frame 6 have their cut surfaces 5 (first frame side cut surfaces). 605 and the second frame side cut surface 1004) are pressed and pressed.

  At the time of this pressure contact, the first engagement portion 1002 having a concave shape provided on the outer periphery of the air suction port 201 of the second frame 7 and the second frame 7 side of the second air passage member 212 are provided. The second engaging portion 707 having a convex shape is also pressed and pressed.

  As described above, the first frame 6 and the second frame 7 are pressed at the cut surfaces by bringing the contact surfaces of the second protrusion 1001 and the second locking portion 704 into pressure contact with each other at the time of screwing. This makes it possible to improve the airtightness of the air passage constituted by the inner surface of the first frame 6 and the inner surface of the second frame 7.

  Similarly, since the second frame 7 and the second air passage member 212 are pressure-bonded by the first engagement portion and the second engagement portion, the space between the air suction port constituted by these and the arrangement space is formed. Confidentiality in the air path can be improved.

  The above is the locking procedure between the second air passage member 212 and the second frame 7 according to the first embodiment, and finally, screwing into the screw hole 1003 of the second frame 7 from the outside of the substantially spherical body. By doing so, the 2nd wind path member 212 and the 2nd flame | frame 7 are crimped | bonded, and the air blower 1 is completed. This screwing is also intended to prevent the movement (displacement) of the second air passage member 212 and the second frame 7 in the circumferential direction. Therefore, regardless of the number of screws to be used, the second air path member 212 can be constantly and evenly pressurized from the second frame 7 side. In other words, it is possible to prevent the air density of the air passage from decreasing due to the looseness of the screws, and as a result, air leakage can be prevented.

  As described above, since the blower device has a drive unit (an impeller, a motor, etc.), there is a problem that each part is displaced due to the vibration, and the airtightness is lowered as the usage time is increased. In particular, due to the shape of the sphere, a twisting force is generated in the circumferential direction around the axis, and this point also promotes the displacement of each part.

  On the other hand, the blower device 1 according to the embodiment of the present invention abuts the first frame 6 and the second frame 7 with the circular cut surfaces coincided with each other, and rotates one frame in the circumferential direction to bring the frames into contact with each other. Screwed together. Thereby, since the 2nd flame | frame 7 crimps | bonds the 1st air path member 204 to the 1st frame 6 via the 2nd air path member 212, the airtightness of an air path can be improved.

  Further, when the high-pressure air generator 211 is configured to be fixed to the first air passage member 204, the screwing rotation direction (rotational direction in the circumferential direction) is the rotation of the blades 210 constituting the high-pressure air generator 211. The second air passage member 212 is rotated in the opposite direction with respect to the direction.

  In this configuration, the force applied to the first frame 6, the first air passage member 204, and the second air passage member 212 due to the rotation of the blades 210 is in the direction in which the pressure due to screwing increases, so even for long-term use. Looseness of each part can be prevented, that is, deterioration of airtightness can be prevented.

  Further, the support portion and the abutting portion are brought into pressure contact with each other in the direction of repulsion when screwed together, and as a result, the first air passage member 204 is placed on the first frame 6 and the second air passage member 212 is placed on the second frame 7. Can be pressed and pressed. Thereby, the airtightness of the air flow path constituted by the first airflow path member 204 and the first frame 6 can be improved, and at the same time, the airtightness of the induced airflow path from the induced air inlet 8 to the induced air outlet 10 This also improves the performance and prevents the mutual airflows from interfering with each other. Similarly, the confidentiality of the air passage that communicates the second air passage member 212 and the second frame 7 can also be improved.

  In the above configuration, all of the first protrusion 601, the first locking part 702, the second protrusion 1001, and the second locking part 704 are two poles, that is, a ventilation side electrode and a suction side electrode during screwing. The pressure welding structure in which pressure is pressed in the center direction of the sphere has been described. However, at least one of the first protrusion 601, the first locking part 702, the second protrusion 1001, and the second locking part 704 may have a pressure contact structure. Even in this case, the airtightness of the air passage can be improved similarly.

  In the first embodiment, as an example, an example in which six attracting air suction ports 8, support portions, contact portions, protrusions, locking portions, and the like are provided at equal intervals on the circumference has been described. Is not limited to six and may be three or more. Moreover, it does not necessarily need to be equally spaced, and each member (support parts, contact parts, first protrusions, second protrusions, first locking parts, second locking parts). It is only necessary that the central axis 2 is included inside a polygon formed by connecting connecting lines. As a result, the first air passage member 204 is in close contact with the first frame 6 at the time of pressure contact between the first frame 6 and the second frame 7, so each member (particularly the opening 9 and the induced air outlet 10). There will be no misalignment.

  In addition, although the air blower was demonstrated in Embodiment 1, it is also possible to distribute | circulate independently as a housing | casing for air blowers in the state which does not attach a high pressure air generator.

  Next, other feature points in the present embodiment will be described.

  As described above, the blower device 1 according to the present embodiment has a spherical shape in which the substantially hemispherical first frame 6 and the substantially semispherical second frame 7 are combined.

  Therefore, for example, when the user wants to obtain a refreshing feeling by applying wind to himself, the user can use it by rotating this appropriately and directing the opening 9 toward him / her. In order to improve the operability in that case, the configuration of FIG. 12 is adopted in the present embodiment.

  That is, in the first frame 6, that is, the main body, an operation unit 1201 that instructs the operation of the high-pressure air generator 211 is provided on the second frame 7 side of the attracting air suction port 8, that is, on the suction side pole 4 side. Further, a display unit 1202 that indicates the operating state of the high-pressure air generator 211 is provided on the second frame 7 side of the operation unit 1201, that is, on the suction side electrode 4 side.

  However, the operation unit 1201 and the display unit 1202 are not necessarily provided on the first frame 6. For example, as shown in FIG. 13, the operation unit 1201 and the display unit 1202 may be provided in the second frame 7, the operation unit is provided in the first frame 6, and the display unit is provided in the second frame 7. It doesn't matter. FIG. 13 is a schematic diagram of a blower device showing a modification of the first embodiment.

  Note that the operation unit 1201 includes three buttons, and the amount of air blow can be set in three stages: small, medium, and large.

  In addition, by operating the operation unit 1201, the display unit 1202 including three lamps displays whether the high-pressure air generator 211 is in a small air volume operation, a medium air volume operation, or a large air volume operation. Yes.

  As described above, the air blower 1 of the present embodiment has a spherical shape that combines the substantially hemispherical first frame 6 and the substantially hemispherical second frame 7. For example, when it is desired to obtain a refreshing feeling by applying a wind to itself, for example, as shown in FIG. 14, it is used by rotating this appropriately and directing the opening 9 toward itself. .

  At this time, as is understood from FIG. 14, the attraction air suction port 8 portion is in a state where the outer peripheral surface portion of the spherical surface is deleted from the outer peripheral surface of the first frame 6, in other words, the outer peripheral surface of the main body. . For this reason, if the operation part 1201 is provided on the second frame 7 side, that is, the suction side pole 4 side, a user on the leeward side (upper extension line of the opening) as a result of the absence of the outer peripheral surface. From the side, it becomes easy to confirm the state of the operation unit 1201, thereby suppressing a decrease in operability.

  In addition, in FIG. 14, the display unit 1202 is not visible, but the display unit 1202 is formed by a lamp. Therefore, by checking the light on the extension line of the operation unit 1201, the high-pressure air generator 211 is It is possible to easily determine whether the operation is a small air volume operation, a medium air volume operation, or a large air volume operation.

  Further, in the first frame 6, that is, the main body, at least one of the operation unit 1201 and the display unit 1202 that instructs the operation of the high-pressure air generator 211 on the second frame 7 side of the attracting air suction port 8, that is, the suction side pole 4 side. For example, a control unit (not shown) connected to the operation unit 1201 or the display unit 1202 is provided in the first frame 6 or the second frame 7 facing the operation unit 1201 and the display unit 1202. Therefore, the deterioration of the air blowing characteristics can be suppressed.

  Note that details of positions for suppressing deterioration of the air blowing characteristics of the operation unit and the display unit will be described with reference to FIG. Here, FIG. 15 is a schematic diagram showing the positions of the operation unit and the display unit of the blower according to Embodiment 1 of the present invention.

  The other pole side of the attraction air suction port will be described in more detail. As shown in FIG. 15, the center axis 2 out of the intersection A4101 of the center axis 2 and the opening 9 and the edge forming the attraction air suction port 8. In a region A4105 (region surrounded by a dotted line in FIG. 15) surrounded by four points, two points B4102 and C4103 farthest from the point D4104 and a point D4104 on the central axis 2 farthest from the air inlet 8 Thus, it can be a region B4106 (shaded portion in FIG. 15) which is the other pole side of the attraction air suction port. That is, in the first frame 6, that is, in the main body, the portion between the plurality of attraction air suction ports 8 is a portion where the air passage from the high-pressure air generator 211 is provided, and thus the operation unit 1201 and the display unit are provided in this portion. By adopting a configuration in which 1202 does not exist, deterioration of the air blowing characteristics can be suppressed.

(Embodiment 2)
Subsequently, in the second embodiment, a configuration including a separation air passage will be described with reference to FIGS. 16 and 17. FIG. 16 is a schematic diagram of the air flow in the blower when there is no operation unit and a display unit, and FIG. 17A shows the air flow when the operation unit and the display unit are close to the attraction air intake port. FIG. 17B is a schematic diagram of the air flow in the apparatus, and FIG. 17B is a schematic diagram of the air flow in the air blower according to Embodiment 2 of the present invention.

  As shown in FIG. 16, in the present embodiment, a turbo fan is used as the blade 210. Therefore, the high-pressure air 2101 generated by the high-pressure air generator 211 has a clockwise swirl component in the top view when the blower 1 is viewed from the opening 9 side, that is, the blower-side electrode 3. It is a flow around. That is, the air sucked from the air suction port 201 provided in the vicinity of the central axis 2 becomes high-pressure air 2101 by the turbofan and travels from the central axis to the wall surface of the main body. Further, on the inner wall surface of the main body, an air flow rising toward the opening 9 while being along the inner wall surface in a clockwise direction.

  The high-pressure air 2101 is classified into two flows in the ascending process. One is left air 2102 that flows leftward along the right inner periphery forming surface 3101 that forms the attraction air suction port 8 while having a swirl component. The other is the rightward air 2103 that flows to the right along the left inner peripheral surface 3102 that forms the attraction air suction port 8 by the Coanda effect, as opposed to the leftward air 2102. These two airs flow toward the opening 9. Then, the leftward air 2102 and the rightward air 2103 collide with each other upstream in the immediate vicinity of the opening 9 and cancel each other's swirl components. As a result, the blowing air 2104 in which the swirl component is suppressed is blown out from the opening 9. The blowing air 2104 in which the swirl component is suppressed has high straightness, and a user at a long distance can also obtain a sufficient refreshing feeling. In addition, among the formation surfaces on the inner peripheral side of the induced air suction port 8 located at the center in FIG. 16, the formation surface on the right side of the central axis 2 is the right inner peripheral formation surface 3101, and the formation surface on the left side of the central axis 2 is the left side. The inner periphery forming surface 3102 is used.

  However, as shown in FIG. 17A, when the operation unit 1201 and the display unit 1202 are located close to the attraction air suction port 8, the flow changes as follows.

  That is, in order for the rightward air 2103 shown in FIG. 16 to be formed, after the high-pressure air 2101 wraps around the side surface 2105 that forms the operation unit 1201 and the display unit 1202, Need to flow along. However, such rapid deflection is difficult due to the viscosity of air. For this reason, the separation region 2106 is generated on the side surface 2105, whereby the flow rate of the rightward air 2103 flowing along the left inner peripheral surface 3102 decreases.

  Based on this, since the air volume of the left air 2102 is larger than the air volume of the right air 2103 in the vicinity of the opening 9, even if the left air 2102 and the right air 2103 collide, the swirl component is not suppressed. It flows toward the opening 9 as it is. As a result, the blowing air 2104a having the swirling component is blown out from the opening 9. The blowing wind 2104a having a swirl component has low straightness, and the wind cannot reach a far distance, and the user cannot obtain a sufficient refreshing feeling.

  On the other hand, as shown in FIG. 17B, in the air blower according to the second embodiment of the present invention provided with a separation air passage between the operation unit 1201 and the attraction air suction port 8, the flow is as follows. Thus, the above-mentioned problems are solved.

  That is, the high-pressure branch air 2107 branched from the high-pressure air 2101 flows through a region sandwiched between the attraction air suction port 8, the operation unit 1201 and the display unit 1202, that is, a branch air passage. The high-pressure branch air 2107 flows rightward along the left inner peripheral surface 3102 due to the Coanda effect, similarly to the rightward air 2103 shown in FIG. The leftward air 2102 and the high-pressure branch air 2107 collide in the vicinity of the opening 9 and cancel each other's swirl components. As a result, the blowing air 2104b in which the turning component is suppressed is blown out from the opening. Accordingly, a user at a long distance can also obtain a sufficient refreshing feeling.

  It is useful as a blower that gives a refreshing feeling by blowing air or promotes air circulation in the space.
