JP 2013-224650 A

  The subject in such a conventional air blower was to further enhance the feeling of use.

  That is, in the conventional thing, the main body case was a substantially spherical body. Usually, since the main body case is placed on the base and used, the base prevents the substantially spherical main body case from rolling. However, if the air blower is moved by cleaning or the like and the main body case is temporarily placed directly on the desk, it may roll.

  Therefore, the present invention aims to further enhance the feeling of use.

  In order to achieve the above-described object, the present invention provides a substantially spherical main body case having an air inlet and an air outlet, and a high pressure provided in an air passage communicating the air inlet and the air outlet. And an air generator, and a flat portion is provided at a lower portion of the main body case, thereby achieving an intended purpose.

  According to the air blower according to the present invention, a high-pressure air generator provided in a substantially spherical body case having an air inlet and an air outlet, and an air passage communicating the air inlet and the air outlet. And a flat surface portion is provided in the lower part of the main body case, thereby further enhancing the feeling of use.

  That is, since the flat part is provided in the lower part of the main body case, when the air blower is moved by cleaning or the like, and the main body case is temporarily placed directly on the desk, the flat part is used as a contact surface with the desk. As a result, the main body case can be prevented from rolling, and as a result, the feeling of use can be further enhanced.

(Embodiment 1)
Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings to provide an understanding of the present invention.

  In addition, the following embodiment is an example which actualized this invention, Comprising: The thing of the character which limits the technical scope of this invention is not. 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 main body case 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 shaft 2 is in point contact with a spherical air blowing side electrode 3 and a suction side electrode 4 facing the air blowing side electrode 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.

  The main body case 1 includes a first frame 6 having a substantially hemispherical shape with a cut surface 5 perpendicular to the central axis 2 at a position equidistant from both spherical poles (the ventilation 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 a suction side electrode 4, has a hollow shape, and includes an air suction port described later around the suction side electrode 4. A filter portion 405 is detachably provided at the air suction port. The second frame 7 has a hemispherical structure when the filter portion 405 is provided at the air suction port.

  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 air blower includes a first air passage member 204 in a hollow space (inside) of a substantially spherical body composed of the first frame 6, the second frame 7, and the filter portion 405. The arrangement space 216 and the second air passage member 212 are arranged in this order from the first frame 6, and this configuration constitutes the 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.

  The second frame 7 includes an air suction port 201 in the vicinity of the suction side electrode 4 as a center. The air suction port 201 includes a filter part 405 that is detachable. The filter part 405 is provided with a number of punching holes. The external air is sucked into the substantially spherical main body through the filter unit 405, 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 blades 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 a ventilation apparatus 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 an air blower in the plane containing the center axis | shaft 2. FIG. 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 filter unit 405 (see the air blowing path 303). The sucked air passes through the air suction port 201 of the first frame 6, and the second air passage member 212 having a function as an orifice has an opening on the air suction port 201 side (an air suction port side opening 302. ) Through the blade 210 in the arrangement space 216 (center portion). 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 307 is configured. As a result, the air sucked from the air suction port 201 is blown out as an annular air flow from the air outlet 307 in a direction parallel to the central axis 2 and away from the center 301 by the action of the blades 210.

  That is, the main body case 1 includes an air outlet 307 and an air suction port, and a filter portion 405 is provided in the air suction port. A high-pressure air generator 211 is provided in the air passage that communicates the air inlet and the air outlet 307. The high-pressure air generator 211 sucks the air sucked from the filter unit 405 into the high-pressure air generator 211 through the air suction port 201 and blows it to the air outlet 307.

  The annular air flow blown out from the air outlet 307 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 blowing 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 according to the first embodiment.

  The main body case 1 has a substantially spherical shape, and includes an air outlet 307 at the top of the main body case 1 and an air inlet 201 at the bottom. A high-pressure air generator 211 is provided in the air passage that communicates the air inlet 201 and the air outlet 307. The high-pressure air generator 211 blows the air sucked from the air suction port 201 out of the main body case 1 through the air outlet 307.

  FIG. 5 is a cross-sectional view of the blower. FIG. 6 is a development view of the blower. FIG. 7 is a developed cross-sectional view of the blower. FIG. 8 is an exploded perspective view of the blower. As shown in FIGS. 5, 6, 7, and 8, a feature of this embodiment is that a disk-shaped flat portion 400 is provided at the lower portion of the main body case 1.

  Specifically, the main body case 1 has a substantially hemispherical first shape with a cut surface 5 perpendicular to the central axis 2 at a position equidistant from the spherical poles (the blowing side pole 3 and the suction side pole 4). The frame 6 and a second frame 7 that is also substantially hemispherical are divided into two equal parts.

  The second frame 7 includes a spherical part 401, a conical part 402, a cylindrical part 403, and a flat part 400 in order from the top, and these are integrally molded from a resin material. From the upper end of the second frame 7 to the central portion in the downward direction is an annular sphere 401 that forms the same plane as the substantially spherical shape. A portion from the lower end of the spherical body portion 401 is a conical portion 402 having a truncated cone shape that becomes thinner toward the lower side. A large number of openings 404 are provided on the side surface of the conical portion 402. These openings 404 are air suction ports 201. A cylindrical cylindrical portion 403 extending downward from the distal end of the conical portion 402 is provided at the distal end of the conical portion 402. At the lower end of the cylindrical portion 403, that is, at the bottom of the second frame 7, a flat portion 400 that covers the lower opening of the cylindrical portion 403 is provided.

  Thus, since the flat part 400 was provided in the lower part of the main body case 1, when the air blower is moved by cleaning or the like and the main body case 1 is temporarily placed directly on the desk, the flat part 400 is replaced with the desk. By using the contact surface, it is possible to suppress the body case 1 from rolling, and as a result, it is possible to further enhance the feeling of use.

  Further, a filter portion 405 is provided on the periphery of the flat portion 400. The filter unit 405 includes a filter 406 and a filter cover 407.

  A filter 406 is provided so as to cover a large number of openings 404 provided on the side surface of the conical portion 402. The filter 406 has a substantially frustoconical shape whose diameter decreases from the upper part toward the lower part, and the lower part is a filter hole 408 that is a circular hole into which the cylindrical part 403 and the flat part 400 that are part of the main body case 1 enter. It has. The filter 406 includes a frame 409 and a net 410. The frame 409 has a substantially conical shape with a circular diameter narrowing from the upper part toward the lower part, and includes a net opening 411 that is a plurality of substantially rectangular holes. A mesh 410 is fixed to the mesh opening 411 of the frame 409. A filter cover 407 is provided outside the filter 406 so as to cover the filter 406.

  A filter cover 407 is provided on the periphery of the flat portion 400. The filter cover 407 has a curved shape that is part of the substantially spherical main body case 1 and has a bowl shape with an upper opening. The filter cover 407 has a large number of holes 412 in an annular shape. These numerous holes 412 are, for example, circular and have a size that does not allow adult fingers to enter. The filter cover 407 is a lower part of the filter cover 407 and is a cover hole 413 which is a circular hole into which the cylindrical portion 403 and the flat portion 400 which are a part of the main body case 1 enter the center of a large number of annular holes 412. have. From this cover hole 413, the plane part 400 protrudes downward.

  Thus, since the filter part 405 is provided on the periphery of the cylindrical part 403 and the flat part 400 which are a part of the main body case 1 and the flat part 400 protrudes downward from the filter part 405, the main case 1 is directly attached to the desk. Even when the flat part 400 is used as a contact surface with the desk when placed on the filter, the filter part 405 does not come into contact with the desk, so that the filter part 405 is not loaded.

  In addition, a second air passage member 212 that is an orifice is provided in the air passage that communicates the air inlet 201 and the high-pressure air generator 211. A flat surface receiving portion 414 extending from the second air passage member 212 that is an orifice is provided inside the flat surface portion.

  The flat surface receiving portion 414 includes a plurality of leg portions 415 extending downward from the second air passage member 212 that is an orifice, a disc-shaped disc portion 416 provided at the tip of the leg portion 415, and the disc portion. And a cylindrical tube portion 417 extending downward from the periphery of 416. The disc portion 416 is disposed in parallel with the flat portion 400 while facing the flat portion 400.

  In the above configuration, when the main body case 1 is accidentally dropped and the flat surface portion 400 is pushed inward, the conical portion 402 has a large number of openings 404, and thus deforms so as to contract. At this time, the upper surface of the flat surface portion 400 comes into contact with the lower end of the cylindrical portion 417 that is the flat surface receiving portion 414. Thereby, when the main body case 1 is accidentally dropped, the deformation amount of the conical portion 402 that is deformed when the flat surface portion 400 is pushed inward can be suppressed.

  In addition, the second air passage member 212 that is an orifice includes an orifice opening that is a circular opening facing the flat portion 400. The orifice opening 418 is slightly larger than the disk portion 416. The leg portion 415 has an elongated plate shape and extends downward from the periphery of the orifice opening 418 and is inclined toward the center of the orifice opening 418. Leg portion 415 includes a plane parallel to the central axis of orifice opening 418. Thereby, since the air sucked into the orifice opening 418 flows along the surface of the leg portion 415, it is possible to suppress an increase in blowing resistance, and the strength against a load applied when the main body case 1 is accidentally dropped is improved.

  Since the conical part 402 extends from the spherical part 401, the force applied to the flat part 400 is received by the spherical part 401. The spherical body portion 401 has an annular substantially spherical shape. On the other hand, since the leg portion 415 extends from the peripheral edge of the orifice opening 418, the force applied to the lower end of the cylindrical portion 417 is received by the second air passage member 212 which is an orifice. The peripheral edge of the orifice opening 418 is a surface extending in the horizontal direction, and is provided with the orifice opening 418 which is a circular opening. Therefore, the orifice opening 418 is more easily bent in the vertical direction than the spherical body portion 401. That is, the force received by the cylinder portion 417 is smaller than the force received by the flat portion 400.

  Therefore, the cylindrical portion 417 that is a flat surface receiving portion is provided with a predetermined distance A from the flat surface portion 400. The predetermined distance A is about 3 mm as an example, and is a dimension that does not break even if the conical portion 402 having a large number of openings 404 is deformed so as to shrink. Thereby, when the main body case 1 is accidentally dropped and the flat surface portion 400 is pushed inward by the first force, the conical portion 402 is first deformed so as to be contracted, and then deformed by a predetermined distance, The upper surface of the portion 400 is in contact with the lower end of the cylindrical portion 417. As described above, after the conical portion 402 is deformed by the predetermined distance A, the upper surface of the flat portion 400 contacts the lower end of the cylindrical portion 417. Therefore, the force applied simultaneously to the flat portion 400 and the cylindrical portion 417 is the first force. It is thought that the 2nd force smaller than this force is applied. Since this second force is distributed and applied to the flat surface portion 400 and the cylindrical portion 417, the force applied to the flat surface portion 400 and the cylindrical portion 417 is smaller than the second force. Thereby, although the force received by the cylinder part 417 is smaller than the force received by the plane part 400, as a result, the strength against the load applied when the main body case 1 is accidentally dropped is improved.

  If the structure is such that the flat portion 400 and the cylindrical portion 417 are in contact with each other, first, a first force is applied to the flat portion 400 and the cylindrical portion 417 simultaneously. Here, although distributed to the plane part 400 and the cylinder part 417, the force applied to the cylinder part becomes larger than that described above, the deformation at the periphery of the orifice opening 418 becomes larger, and the second air passage member 212 which is the orifice becomes larger. It may be damaged.

  In addition, a high pressure air generator 211, a blade 210, a second air path member 212 that is an orifice, and a filter unit 405 are disposed on the second frame 7 that is a lower part of the main body case 1. That is, since a heavy part is arranged in the lower part of the main body case 1, the center of gravity is located in the lower part of the substantially spherical main body case 1. Thus, when the air blower is moved by cleaning or the like, and the main body case is temporarily placed directly on the desk, the curved surface is a part of the substantially spherical main body case 1 that is the periphery of the flat portion 400. When the filter cover 407 is used as a contact surface with the desk, the center of gravity is at the lower portion, so that it rises due to its own weight, and the flat portion 400 becomes the contact surface with the desk. As a result, the main body case 1 can be prevented from rolling, and the usability can be further enhanced.

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