Description

Technical Field

[0001] The present invention relates to an article having a function of cooling the body by circulating air inside, such as an air-conditioning sheet such as an air-conditioning clothing, an air-conditioning futon, and an air-conditioning rucksack, and a blower device used by being mounted on a helmet ventilation device or the like.

Background Art

[0002] In recent years, articles having a function of cooling the body by circulating air inside by a fan, such as air-conditioning clothing that introduces outside air into the clothing to cool the wearer's body, an air-conditioning futon that arranges a spacer between upper and lower two sheets and circulates air in this spacer to cool the contact portion with the body, an air-conditioning sheet such as an air-conditioning rucksack, and a helmet ventilation device that circulates air inside the helmet have been put into practical use.

[0003] All of these articles are formed by opening mounting holes in a sheet-like member and attaching a blower device to the mounting holes. However, a conventional blower device uses an axial flow blower such as a propeller fan, and thereby, an air flow in a direction substantially perpendicular to the sheet-like member is formed (see, for example, Patent Document 1).

[0004] In addition, the following structure is used as a structure for attaching such a blower device to a sheet-like member. That is, it includes a fan body and an annular locking member for attaching the fan body to a sheet-like member. The fan body has a hollow cylindrical portion and a flange portion protruding from the upper end of the cylindrical portion in a direction substantially perpendicular to the side surface of the cylindrical portion. Then, after inserting the cylindrical portion into a mounting hole formed in the sheet-like member, an annular locking member is inserted from the inner surface side of the sheet-like member to the outer periphery of the cylindrical portion, and the sheet-like member is sandwiched between the back surface of the flange portion and the end surface of the annular locking member. At the same time, the fan is attached to the sheet-like member by engaging a locking piece provided on the cylindrical portion with a protrusion provided on the annular locking member (see, for example, Patent Document 1).

Summary of the Invention

Problems to be Solved by the Invention

[0006] When using a blower device as described above, in order to cool the body by circulating air inside an air - conditioned garment or the like, it is necessary to change the direction of the air flow, which is formed substantially perpendicular to the sheet - like member by an axial - flow fan, by 90 degrees to create an air flow parallel to the body. For example, in an air - conditioned garment, the introduced air is made to collide with the wearer's body or underwear, thereby changing the direction of the air flow to a direction along the wearer's body or underwear.

[0007] However, in such a structure, since the air flow velocity is inevitably decelerated in the process of changing the direction of the air flow by 90 degrees, the loss is large and the cooling efficiency is poor.

Best Mode for Carrying Out the Invention

[0021] Hereinafter, a blower device according to an embodiment of the present invention will be described with reference to FIGS. 1 to 10. In the following description, based on the state where the blower device is attached to a sheet-like member, the outer surface direction of the sheet-like member is defined as upward and the inner surface direction is defined as downward for explanation.

[0022] [First Embodiment] The blower device 100 according to the first embodiment will be described with reference to FIGS. 1 to 6.

[0023] [Description of Configuration] As shown in FIG. 1, the blower device 100 includes a fan body 1 that forms an air flow, a case body 2 that houses the fan body 1, and a connector (not shown) for supplying power to the fan body 1.

[0024] (Fan Body) The fan body 1 is a turbo fan that blows air in a direction substantially perpendicular to the rotation axis. As shown in FIG. 2, the fan body 1 includes a motor 11, a plurality of blades 12..., and a bottom plate 13. The fan body 1 is housed in the case body 2 such that the rotation axis of the motor 11 is substantially parallel to the vertical direction.

[0025] (Motor) For example, an outer rotor type brushless motor is used as the motor 11. The motor 11 has a rotating part 111 and a non-rotating part 112, and is formed such that the rotating part 111 rotates with respect to the non-rotating part 112. The rotation axis of the motor 11 is in the vertical direction, that is, a direction substantially perpendicular to the plane of the paper in FIG. 2(a).

[0026] (Blades) The blades 12... are attached to the rotating part 111 of the motor 11, rotate with the rotation of the rotating part 111, and blow air in a direction substantially perpendicular to the rotation axis of the motor 11. As shown in Fig. 2, the blade 12 is formed in a substantially rectangular plate shape with the short side being substantially parallel to the rotation axis of the motor 11, the long side extending in a direction substantially perpendicular to the rotation axis, and curving backward with respect to the rotation direction as it goes outward.

[0027] (Bottom plate) As shown in Fig. 2(a), the bottom plate 13 is a circular plate-shaped member having substantially the same diameter as the rotation range of the blade 12... and is connected to the lower end of the blade 12.... The bottom plate 13 is fixed to the rotating part 111 of the motor 11 and rotates together with the blade 12... as the rotating part 111 of the motor 11 rotates.

[0028] {Case body} As shown in Fig. 3, the case body 2 includes a bottom part 21, an air intake part 22, a mounting part 23, and an exhaust part 24, and is formed in a substantially cylindrical shape as a whole. Inside the case body 2, the fan main body 1 is housed. When the fan main body 1 is operated, outside air is taken in from the air intake part 22 and discharged from the exhaust part 24.

[0029] (Bottom part) The bottom part 21 includes a bottom body 211 and a fixing part 212. The bottom body 211 is a plate-shaped member formed in a disk shape and is formed into a circle having a diameter larger than the rotation range of the blade 12... when viewed from the direction of the rotation axis of the motor 11. The fixing part 212 is a part for fixing the non-rotating part 112 of the motor 11 so that the rotation axis of the motor 11 is substantially perpendicular to the bottom body 211, and is provided at the central part of the bottom body 211. Note that the bottom part 21 can adopt any configuration as long as it can fix the non-rotating part 112 of the motor 11 so that the rotation axis of the motor 11 is substantially horizontal in the vertical direction.

[0030] (Air intake part) The air intake part 22 is a part for taking in outside air inside the blower device 100 and is formed into a circle substantially congruent with the bottom body 211 when viewed from the direction of the rotation axis of the motor 11. As shown in Fig. 3(a), the intake part 22 includes a circular central base part 221, a plurality of rod-shaped parts 222 extending radially from the central base part 221, and a ring-shaped annular part 223 centered on the central base part 221. A gap communicating with the inside of the case body 2 is formed between these parts.

[0031] Due to this configuration, the intake part 22 has sufficient air permeability, and when the internal fan body 1 is rotated, outside air can be taken into the case body 2. In addition, the intake part 22 is configured such that fingers or the like do not enter from the outside into the case body 2 and are not caught by the rotating blades 12. Therefore, it is desirable that the gap formed between the central base part 221, the rod-shaped parts 222, and the annular part 223 is only large enough that a finger cannot enter.

[0032] (Mounting part) As shown in Fig. 3(b), the mounting part 23 includes a ring-shaped member 231, an outer surface side flange 232, and an inner surface side flange 233.

[0033] The ring-shaped member 231 is formed on an annular ring having an outer shape substantially the same as the diameters of the bottom body 211 of the bottom part 21 and the intake part 22, and is connected to the lower surface side of the intake part 22. The outer surface side flange 232 is provided at the upper end of the ring-shaped member 231, and the inner surface side flange 233 is provided at the lower end. As a result, a groove part 234 is formed between the outer surface side flange 232 and the inner surface side flange 233. It is desirable that the groove part 234 has a width substantially the same as the thickness around the opening hole of the sheet-like member 200 in the vertical direction so that the sheet-like member 200 inserted into the groove part 234 is difficult to come off, as will be described later.

[0034] The outer surface side flange 232 is formed to extend annularly from the upper end of the ring-shaped member 231 in a direction substantially perpendicular to the rotation axis of the motor 11. The inner surface side flange 233 is formed to extend annularly from the lower end of the ring-shaped member 231 in a direction substantially perpendicular to the rotation axis of the motor 11. In addition, when attaching the blower 100 to the sheet-like member 200 as described later, in order to facilitate inserting the blower 100 into the mounting hole of the sheet-like member 200, the outer surface side flange 232 and the inner surface side flange 233 may be formed to extend obliquely upward or downward from a direction perpendicular to the rotation axis of the motor 11. Also, the outer surface side flange 232 and the inner surface side flange 233 only need to be formed such that a groove portion 234 is formed therebetween, and do not necessarily have to extend from the upper end portion or the lower end portion of the ring-shaped member 231.

[0035] As shown in Fig. 3(a), the inner surface side flange 233 extends larger than the outer surface side flange 232 and is formed to have a diameter larger than that of the outer surface side flange 232 when viewed from the direction of the rotation axis of the motor 11.

[0036] Note that, as shown in Fig. 1, the mounting portion 23 is not provided at a portion of the side surface of the case body 2 that faces the outer peripheral portion of the blade 12... so as not to interfere with the air blowing by the fan main body 1, and it is desirable that the mounting portion 23 is provided above the outer peripheral portion of the blade 12...

[0037] (Exhaust portion) The exhaust portion 24 is a portion that discharges air from the blower 100 and is formed of a plurality of columnar members 241... as shown in Fig. 3(b). The columnar members 241... are arranged in a circumferential shape so as to connect the edge portion of the bottom body 211 and the mounting portion 23, and the entire case body 2 has a substantially cylindrical shape with the bottom body 211 as the lower surface, the intake portion 22 as the upper surface, and the mounting portion 23 and the exhaust portion 24 as the side surfaces.

[0038] Because of being configured in this way, the exhaust portion 24 has sufficient air permeability, and when the internal fan main body 1 is rotated, the outside air flowing in from the intake portion 22 can be discharged from the exhaust portion 24.

[0039] In addition, in order to prevent fingers or the like from entering the inside of the case body 2 from the outside and being caught by the rotating blade 12..., it is desirable that the columnar members 241... be arranged with only a small gap that does not allow fingers to enter.

[0040] {Explanation of the mounting method} When attaching the air blower 100 to air-conditioned clothing or the like, as shown in FIG. 4, the air blower 100 is inserted into a mounting hole (not shown), which is a circular hole formed in the sheet-like member 200 and having a diameter substantially the same as the outer diameter of the ring-shaped member 231, with the intake portion 22 facing the outer surface side. Then, the edge portion around the mounting hole of the sheet-like member 200 is dropped into the groove portion 234 formed between the outer surface side flange 232 and the inner surface side flange 233.

[0041] At this time, since the outer surface side flange 232 is formed with a smaller diameter compared to the inner surface side flange 233, it is easier to drop the edge portion around the mounting hole of the sheet-like member 200 into the groove portion 234 from the side of the outer surface side flange 232.

[0042] In addition, in order to make it easier to attach the air blower 100 to the mounting hole of the sheet-like member 200 and prevent the air blower 100 from coming off as described above, it is desirable that a stretchable member such as a ring-shaped rubber be sewn around the mounting hole of the sheet-like member 200 so that the periphery of the mounting hole has elasticity.

[0043] {Explanation of the effect} According to the present embodiment, the outside air introduced into the air blower 100 from the intake portion 22 of the case body 2 is discharged from the exhaust portion 24 formed in a direction substantially perpendicular to the rotation axis of the motor 11 by the internal fan main body 1. Therefore, the air flow formed by the fan main body 1 becomes a flow parallel to the body without particularly changing the direction. Thus, it is not necessary to change the direction of the air flow by 90 degrees as in a conventional air blower. Therefore, there is no loss when changing the direction of the air flow, and the cooling efficiency can be improved.

[0044] In addition, in the case of a structure in which an annular locking member is inserted and fixed from the inner surface side of a sheet-like member into the cylindrical portion of the fan body as in a conventional blower, since the cylindrical portion and the locking member are located on the side of the blade of the fan body, it becomes an obstacle to discharging air from the blower in a direction substantially perpendicular to the rotation axis of the motor. On the other hand, according to the present embodiment, since the blower 100 is attached to the sheet-like member 200 by the groove portion 234 between the outer surface side flange 232 and the inner surface side flange 233, most of the side surface of the case body 2 except for the attachment portion 23 can be used as the exhaust portion 24, without hindering the discharge of air from the blower 100.

[0045] Further, when it is necessary to change the direction of the air flow by 90 degrees as in a conventional blower, it is essential to provide a space inside or outside the blower for converting the air flow in a direction substantially perpendicular to the sheet-like member formed by the fan body into a direction substantially parallel to the sheet-like member. Therefore, it is difficult to form the vicinity of the blower for air-conditioning clothes or the like thinly. On the other hand, according to the blower 100 according to the present embodiment, since the air flow in a direction substantially parallel to the sheet-like member 200 is formed by the fan body 1, there is no need to provide the above-described space, and it becomes possible to form the vicinity of the blower for air-conditioning clothes or the like thinly.

[0046] In addition, when it is necessary to change the direction of the air flow by 90 degrees as in a conventional blower, noise is likely to occur in the process. However, according to the present embodiment, since there is no need to change the direction of the air flow formed by the fan body 1, the quietness can also be improved.

[0047] {Modification} As shown in FIG. 5, the attachment portion 23A may be formed by a ring-shaped member 231A in which a groove is dug in the outer periphery and a groove portion 234A is formed without providing the outer surface side flange 232 and the inner surface side flange 233.

[0048] As shown in FIG. 6, after forming the mounting portion 23 such that the vertical width of the groove portion 234 is larger than the thickness of the sheet-like member 200, an elastic ring 3, which is an annular member having an inner diameter substantially the same as the outer diameter of the ring-shaped member 231 formed of an elastic material in addition to the sheet-like member 200, is attached to the groove portion 234. Thereby, the edge portion around the mounting hole of the sheet-like member 200 may be pressed against the upper or lower wall portion of the groove portion 234, that is, the lower surface of the outer surface side flange 232 or the upper surface of the inner surface side flange 233. In FIG. 6, the case where the elastic ring 3 is attached above the sheet-like member 200 and the sheet-like member 200 is pressed against the upper surface of the inner surface side flange 233 is illustrated. Thereby, the blower device 100 can be made more difficult to come off from the mounting hole of the sheet-like member 200.

[0049] Note that the elastic ring 3 may be formed in an elliptical shape. When formed in an elliptical shape, it has an inner circumference larger than the outer circumference of the ring-shaped member 231 and is formed such that the minor axis of the inner circumference is smaller than the diameter of the outer circumference of the ring-shaped member 231. Thereby, the minor axis side of the elastic ring 3 strongly contacts the ring-shaped member 231, and the blower device 100 can be made more difficult to come off. When attaching the elliptical elastic ring 3, it may be attached after pinching the major axis side with a finger and making it a perfect circle having a diameter larger than that of the ring-shaped member 231.

[0050] [Second Embodiment] The blower device 100B according to the second embodiment will be described with reference to FIGS. 7 and 8. Note that the description of the same parts as those in the first embodiment will be omitted.

[0051] As shown in Fig. 7(a), in the case body 2B according to the second embodiment, the mounting portion 23B is not provided with an outer surface side flange 232. Instead, a male screw portion 235 is provided on the outer surface side of the ring-shaped member 231. Further, in this case, the inner surface side flange 233 does not necessarily have to be formed at the lower end portion of the ring-shaped member 231, and can be formed at any position of the ring-shaped member 231 as long as a space for providing the male screw portion 235 can be secured.

[0052] Further, as shown in Fig. 7(b), the blower device 100B according to the second embodiment includes a mounting ring 4 which is an annular member formed such that the width in the vertical direction is substantially the same as the width in the vertical direction of the portion above the inner surface side flange 233 of the ring-shaped member 231, and the inner diameter is substantially the same as the outer shape of the ring-shaped member 231. On the inner surface side of the mounting ring 4, a female screw portion (not shown) that engages with the male screw portion 235 is provided.

[0053] In the present embodiment, as shown in Fig. 8, the case body 2 is inserted into the mounting hole of the sheet-like member 200 from the inner surface side of the sheet-like member 200. After bringing the upper surface of the inner surface side flange 233 into contact with the edge portion around the mounting hole of the sheet-like member 200, the mounting ring 4 is inserted into the ring-shaped member 231 of the mounting portion 23 from the outer surface side of the sheet-like member 200, and the male screw portion 235 is screwed with the female screw portion of the mounting ring 4. As a result, the mounting ring 4 is fixed to the case body 2 in a state where the edge portion around the mounting hole of the sheet-like member 200 is sandwiched between the lower end portion of the mounting ring 4 and the upper surface side of the inner surface side flange 233, and the blower device 100B can be attached to the sheet-like member 200.

[0054] Conversely, the ring-shaped member 231 may be provided with a female screw portion and the mounting ring 4 may be provided with a male screw portion.

[0055] Further, the fixing method of the ring-shaped member 231 and the mounting ring 4 is not limited to the method using screws, and any configuration can be adopted as long as the two can be fixed.

[0056] For example, a configuration in which a protrusion provided on the inner surface side of the mounting ring 4 is engaged with a recess provided on the outer surface side of the ring-shaped member 231 may be used.

[0057] In this case, the mounting ring 4 may be formed in a perfect circle, but it may also be elliptical with the protrusion formed on the inner surface on the minor axis side. In this case, it has an inner circumference larger than the outer circumference of the ring-shaped member 231, and the minor axis of the inner circumference is formed to be smaller than the diameter of the outer circumference of the ring-shaped member 231. Thereby, the protrusion provided on the minor axis side of the mounting ring 4 can be strongly engaged with the recess of the ring-shaped member 231, making it difficult for the blower device 100 to come off. When attaching the elliptical mounting ring 4, it may be attached after pinching the major axis side with a finger and making it a perfect circle with a diameter larger than that of the ring-shaped member 231.

[0058] Also according to this embodiment, the same effects as those of the first embodiment can be obtained.

[0059] [Third Embodiment] The blower device 100C according to the third embodiment will be described with reference to FIG. 9. Note that the description of the same parts as those in the first embodiment will be omitted.

[0060] The case body 2C according to the third embodiment does not have an inner surface side flange 233 in the mounting portion 23C. Instead, as shown in FIG. 9, a hook-and-loop fastener 236 is provided on the lower surface side of the outer surface side flange 232. Also, in this case, the outer surface side flange 232 does not necessarily have to be formed at the upper end portion of the ring-shaped member 231 and can be formed at any position of the ring-shaped member 231.

[0061] Also, when using this embodiment, a hook-and-loop fastener is also provided around the mounting hole on the outer surface side of the sheet-like member 200. After inserting the blower device 100C into the mounting hole of the sheet-like member 200 from the outer surface side, these hook-and-loop fasteners are joined to attach the blower device 100C to the sheet-like member 200.

[0062] Even with this embodiment, the same effects as those of the first embodiment can be obtained.

[0063] [Modification Example] In any of the embodiments, the main body of the fan housed in the blower device is not limited to a turbo fan, and any other configuration can be adopted as long as it is a centrifugal blower that can discharge air in a direction substantially perpendicular to the rotation axis.

[0064] In any of the embodiments, as the intake part 22, in addition to the central base part 221, the rod-shaped part 222... and the ring-shaped part 223..., a net-like member with a large aperture ratio that covers the opening between these may be used in combination. As a result, even if the gap between the central base part 221, the rod-shaped part 222... and the ring-shaped part 223... is increased, a finger cannot enter, so it becomes possible to further increase the aperture ratio. Similarly, for the exhaust part 24, in addition to the columnar members 241..., a net-like member with a large aperture ratio that covers the opening between the columnar members 241... may be used in combination.

[0065] In any of the embodiments, as long as the blades of the fan main body can blow air in a direction substantially perpendicular to the rotation axis of the motor 11 as the rotation part 111 of the motor 11 rotates, blades of any shape can be used. For example, like the fan main body 1A shown in FIG. 10, one provided with blades 12A... having a shape in which the upper side is inclined toward the outer peripheral part may be used. Note that regardless of the shape of the blades, in order not to interfere with the air blowing by the fan main body, it is desirable that the attachment part 23 is not provided on the part of the side surface of the case body 2 that faces the outer peripheral part of the blades, but is provided above the blades.
