Description

The present invention provides an air-conditioned clothing blower for suppressing sweating of the wearer by blowing outside air into the clothes worn by workers who perform various operations in summer or in a high temperature environment. Regarding the air-conditioned clothing used.

For example, it has an air intake port, blades, and a motor, takes in air from an air suction port provided on the front surface, and blows out air in the side direction from a parallel wind sending part provided on the side surface, which is substantially parallel to the human body. A parallel wind generating means for generating parallel wind and an air outlet portion are included, and the parallel wind generating means is used as a side flow fan (white fan or turbo fan), a mixed flow fan, or a propeller (axial flow) fan. Any cooling garment has been proposed (see, for example, Patent Document 1).

However, when a propeller fan or a mixed flow fan is used as the parallel wind generating means in the cooling garment, a relatively large-diameter parallel wind conversion plate is used for the human body in order to make the generated large amount of air parallel to the human body. It is necessary to prepare it integrally on the side. Therefore, the area of the fan guard formed at the air outlet portion of the parallel wind is limited, the parallel wind generating means becomes large and heavy, and the parallel wind is blown out unevenly. There was a problem of causing discomfort to the user.
Further, the oblique flow fan (see FIGS. 9 and 10 of Patent Document 1) has an inclination angle of about 15 degrees from the base end side to the tip end side of the blade with respect to a virtual plane orthogonal to the rotation axis of the motor. Since it has, it was difficult to arrange a sufficient space on the air suction side.
On the other hand, when the sirocco fan or the like is used, a relatively high static pressure can be obtained, but the amount of air generated is small, so that it is difficult to send sufficient air to the entire long gap between the cooling clothes and the human body. Moreover, since the structure including the plurality of blades is complicated, it is difficult to miniaturize it, and the cost is high, there is a problem that it is difficult to apply it to the cooling garment.

Japanese Patent No. 4329118 (pages 1 to 16, FIGS. 1 to 14)

The present invention solves the problems described in the background art, and uses a fan having a relatively simple structure that does not use the parallel wind conversion plate or the like to convert the air sucked from the outside into a high wind pressure and a large air volume. An object of the present invention is to provide an air-conditioning clothing blower capable of relatively uniformly blowing air into a gap between clothes and the human body side, and an air-conditioning clothing using the air-conditioning clothing.

Means for Solving Problems and Effects of Invention

In order to solve the above problems, the present invention uses an open axial flow fan as a fan to be attached to an air-conditioning garment, and the number of blades protruding from the outer peripheral surface of the spinner in the fan and the three-dimensional shape of the blades. It was made by layering on identifying and.
That is, the air-conditioning garment blower of the present invention (claim 1) is an air-conditioning device that is attached to an opening hole provided in the cloth of the garment and blows outside air to the inside of the garment to suppress sweating of the wearer. An inner cylinder which is a blower for clothes and has a motor and a fan rotated by the motor and has an air supply hole, and an intake hole which is fixed to the outer side of the inner cylinder in the clothes and for introducing outside air. The fan includes an outer cylinder having a flange protruding in the radial direction on the outer peripheral surface, and a ring body having an annular shape as a whole and being screwed to the outer peripheral surface of the inner cylinder. It consists of a spinner connected to the rotation shaft of the motor and 8 to 10 blades radially protruding from the outer peripheral surface of the spinner, and the blades are formed on the outer peripheral surface of the spinner in the radial direction of the spinner. The blade base is connected to the surface along the blade at an inclination angle of 30 to 34 degrees to the tip side of the spinner in the rotation direction of the blade, and extends from the blade base toward the tip side in a curved shape, and is described above. It has a blade tip portion whose inclination angle toward the tip end side of the spinner in the rotation direction of the blade is 16 to 20 degrees with respect to a surface along the radial direction of the spinner, and the blade tip portion. On the rear side surface of the blade, which is on the rear side in the rotational direction with respect to the surface along the radial direction of the spinner, the blade is 4 to 7 degrees toward the tip surface side of the spinner from the blade base to the blade tip. It is characterized in that it is tilted at an tilt angle.

According to the air-conditioning clothing blower, the following effects (1) and (2) can be obtained.
(1) In the fan, the number of blades is connected to the outer peripheral surface of the spinner at the blade base portion having the inclination angle, and the blades are formed on a virtual surface along the radial direction of the spinner toward the blade tip portion side. On the other hand, the blade has a blade tip portion having the inclination angle gradually becoming shallower, and the blade is inclined from the blade base portion toward the blade tip portion side toward the tip surface side of the spinner at an angle of 4 to 7 degrees. There is. As a result, the air sucked from the intake hole of the outer cylinder along the axial direction of the spinner can be efficiently blown to the radial side in a relatively narrow space, and the wind pressure (static pressure) is relatively high. With a large amount of air, uniform air can be blown from the air supply holes of the inner cylinder along the inside of the clothes.
(2) Since the parallel wind conversion plate is not used and the fan has a relatively simple and compact structure and is composed of an inexpensive fan, it can be attached to the mounting hole of the air-conditioning clothing for outdoor workers such as in summer. It is possible to provide a comfortable working environment.

For the inner cylinder, outer cylinder, and ring body including the fan constituting the air-conditioning clothing blower, for example, a molded product obtained by injection molding a synthetic resin such as ABS resin is used, but the present invention is limited to this. It is not something that is done.
Further, as the motor, for example, a direct current (DC) motor having an input power of about 2 to 6 W and a rotation speed of about 4000 to 6600 rpm is used.
The spinner has a cylindrical shape as a whole, and has a proximal end side to which the rotation shaft of the motor is connected and a hemispherical distal end surface side located opposite to the proximal end side in the axial direction.
Further, the diameter of the spinner is the same as the length along the radial direction of the blade.
Further, the blades project from the proximal end side (rotating shaft side of the motor) in the axial direction of the spinner along the radial (radiation) direction.
Further, the blades are between a blade base portion connected to the outer peripheral surface of the spinner, a blade tip portion extending from the blade base portion in the radial direction of the spinner and radially along the blade base portion, and between the blade base portion and the blade tip portion. It is located at, and has a front side surface of the blade and a rear side surface of the rear blade in the direction of rotation of the blade, and a blade body surrounded by these.
Further, the reason why the number of blades is 8 to 10 is that 8 or more blades are advantageous in order to obtain sufficient static pressure and air volume in a relatively small and narrow space such as this blower. This is because injection molding with a synthetic resin becomes technically difficult when the number of sheets is 11 or more.

Further, the blade base end portion has a loose arc-shaped cross section that is convex toward the tip end side of the spinner, and the inclination angle of the blade base end portion is a tangent line that becomes a chord of the arc. The reason why the temperature is set to 30 to 34 degrees is that the number of blades is connected to the outer peripheral surface of the spinner at a distance from each other visually in the axial direction of the spinner, and the tilt angle in the radial direction of the spinner is relatively large. This is to make it shallow so that the direction of the wind (air flow) sucked inside the main blower can be easily changed from the axial direction to the radial direction.
Further, the blade tip portion also has a cross section having the same arc shape as described above, and the inclination angle of the blade tip portion is a tangent line to be a chord of the arc, and the inclination angle of the inclination angle is 16 to 20 degrees. The reason for this is that the radial visual inclination angle of the spinner is made shallower, and the direction of the wind sucked into the blower is more reliably converted from the axial direction of the spinner to the radial direction. This is to make it easier to do.
Further, the reason why the blades are tilted 4 to 7 degrees toward the tip surface side of the spinner is to surely change the direction of the wind sucked into the blower from the axial direction of the spinner to the radial direction. ..
In addition, electric power is supplied to the motor from a power source such as a lithium battery housed in an inner pocket sewn inside the air-conditioning clothing via a cable.

Further, in the present invention, the fan has nine blades, and on the rear side surface of the blade, which is on the rear side in the rotation direction, from the blade base portion toward the blade tip portion, 5 degrees to the tip surface side of the spinner. Also included is an air-conditioned garment blower (claim 2) that is tilted at a tilt angle of 6 degrees.
According to these, the air sucked into the main blower can be blown more efficiently in the radial side, and due to the relatively high wind pressure and a large amount of air, the air blown hole of the inner cylinder is along the inside of the clothes. Since the air can be blown more uniformly, the effect (1) can be obtained more reliably.

Further, in the present invention, the tip surface side of the spinner has a hemispherical shape, and the distance between the tip surface of the spinner and the top of the outer cylinder facing the tip surface is 7 mm or more. Also included is a blower for air-conditioned clothing (claim 3) in which the air-conditioning garment is arranged.
According to these, a space having a relatively large volume is formed between the top of the outer cylinder and the tip end surface side of the spinner, and a large amount of air sucked by the fan is efficiently taken out by the blades of the fan. Since it can be taken in to the side, the above effect (1) can be remarkably obtained.
Further, by providing the above interval, noise generated by the blades rotating at high speed can be suppressed, so that quietness can be maintained (hereinafter, referred to as effect (3)).
The hemispherical shape on the tip surface side of the spinner includes not only a geometric hemispherical shape but also a form having an arc-shaped curved surface along the periphery of a flat circular surface on the center side.
Further, the upper limit of the interval is 10 mm in order to keep the size of the blower device small.
Further, in order to secure the space, the outer cylinder has an arc shape or a Mt. Fuji shape in which the visual sense in the axial direction is convex outward including the top.

In addition, in the present invention, at least one of the front side surface of the blade and the rear side surface of the rear blade in the rotation direction of the blade is on the front side or the thickness direction of the blade in the rotation direction. Also included is a blower for air-conditioned clothing (claim 4), in which a wing red extending toward the tip of the spinner is projected.
According to this, with the high speed rotation by each blade of the fan, to suppress the occurrence of vortex flow of air along the rotational direction occurring on the distal end side of each vane, stable rotation locus of each the vane is obtained Therefore, the effect (1) can be more easily obtained.
The wing red has a flat plate shape extending from the tip of the blade in either one of the thickness directions of the blade, or a spindle shape extending from the tip of the blade in at least one of the front and the rear in the rotation direction of the blade. A semi-spindle shape is exemplified.

On the other hand, the air-conditioned garment (claim 5) of the present invention is characterized in that the air-conditioned garment blower is attached to a mounting hole provided in the cloth of the garment.
According to the air-conditioned garment, since the blower device that exerts the effects (1) to (3) is attached to one or more mounting holes provided in the cloth of the garment, it is used for outdoor workers such as summer and high temperature. A comfortable working environment can be reliably guaranteed to workers in the environment (hereinafter referred to as effect (4)).
The air-conditioned garment is mainly intended for a jacket, and the blower is individually attached to a pair of mounting holes provided near the left and right flanks at the back of the jacket. In this case, the two motors and the battery are connected by a branch cable.

Further, as shown in FIG. 5D, the blade tip portion 26 has an inclination angle θ2 of 16 to 20 degrees (for example, 18 degrees) with respect to the surface k. That is, the blade 24 is a curved surface having a three-dimensional shape in which the inclination angle with respect to the surface k gradually decreases from the blade base 25 toward the blade tip 26, and as shown in FIGS. 5 (C) and 5 (D). In addition, it has an arc-shaped cross section that gently inclines toward the tip surface side of the spinner 21.
The inclination angles θ1 and θ2 are measured with reference to the tangents 30 and 31 connecting the rear end surface 23 side and the tip surface (21) side of the spinner 21 in the arc-shaped cross section.

Further, as shown in FIG. 5E, the blade 24 faces the surface k from the blade base 25 to the blade tip 26 on the blade rear side surface 28 which is on the rear side in the rotation direction. The spinner 21 is inclined toward the tip surface (21) side at an inclination angle θ3 of 4 to 7 degrees (for example, 6 degrees).
As shown in FIG. 5E, the inclination angle θ3 is measured with reference to the tangent line 32 connecting the blade base portion 25 and the blade tip portion 26 on the blade rear side surface 28.

As described above, the nine blades 24 of the fan 20 do not visually overlap each other along the axial direction of the spinner 21, and the individual blades 24 are directed from the blade base 25 toward the blade tip 26. The inclination gradually decreases from the angle θ1 to the angle θ2, and the rear side surface 28 side of the blade is inclined to the tip surface side of the spinner 21 at the angle θ3. Therefore, as will be described later, it is possible to supply the wind having a high wind pressure and a large amount of air to the inside of the garment 1 with a relatively small input power.
Moreover, the blade tip portion 26 of each blade 24 is provided with a wing red 29 projecting to the front side in the rotation direction to suppress the generation of a swirl flow of air generated near the tip portion of each blade 24. The rotation locus and the rotation state of the blade 24 can be stabilized.

Further, as shown in FIG. 2B, between the tip surface (21) of the spinner 21 and the inner surface of the top 56 of the outer cylinder 50, along the axial direction of the spinner 21, An interval L of 7 mm or more (for example, about 8 mm) is arranged, and in combination with the hemispherical shape on the tip end surface side of the spinner 21, the spinner 21 and each blade 24 and the outer cylinder 50 are relatively close to each other. A large volume space s is formed. As a result, a large amount of air can be taken into the inside of the outer cylinder 50 and sent to the blade 24 side rotating at high speed, and the noise generated by the high speed rotation of the blade 24 can be suppressed.

In order to form the blower 10 by the inner cylinder 11 including the motor M and the fan 20 as described above, the outer cylinder 50, and the ring body 60, first, the inner cylinder 11 and the outer cylinder 11 and the outer cylinder are formed. After connecting the 50 to each other along the axial direction including the locking means, most of the inner cylinder 11 and the outer cylinder 50 are connected from the outside of the air-conditioning garment 1 to the mounting hole 9 of the garment 1. It is inserted inside and the flange 52 of the outer cylinder 50 is brought into close contact with the outer peripheral edge of the mounting hole 9.
Next, the ring body 60 is brought close to the cylinder peripheral portion 12 of the inner cylinder body 11 connected to the outer cylinder body 50 from the inside of the air-conditioning garment 1, and the double-threaded screw 63 of the ring body 60 and the inner cylinder body 11 The two-threaded screw 13 is screw-bonded to each other. At this time, each time the rotating double-threaded screw 63 is rotated once, the two pitches of the non-rotating side double-threaded screw 13 are moved, that is, when the ring body 60 is rotated once, the ring body 60 is rotated. , The inner cylinder 11 is moved by two pitches with the double-threaded screw 13 along the axial direction of the cylinder peripheral portion 12. Therefore, it can be screw-coupled with half a rotation operation as compared with screwing with a normal single-thread screw.

As a result, as shown in FIGS. 2 (A), 2 (B) and 4, the flange 52 of the outer cylinder 50 connected to the inner cylinder 11 and the ring piece 61 of the ring 60 are formed. The inner peripheral edge of the mounting hole 9 of the garment 1 is tightly sandwiched from both the inner and outer sides.
Moreover, with the screwing operation, the plurality of the uneven strips 66 formed on the ring piece 61 of the ring body 60 bite into the fabric 8 (8a) located inside the mounting hole 9 while rotating. The blower device 10 composed of the inner cylinder 11, the outer cylinder 50, and the ring body 60 can be tightly attached to the garment 1 with the attachment holes 9 of the garment 1 closed. Therefore, even if the inner diameter of the mounting hole 9 and the outer diameter of the peripheral cylinder portion 12 in the inner cylinder 11 are substantially the same, or even if there is a slight difference in the values between the two, the pair does not cause inflow and leakage of outside air. The blower 10 is easily and quickly attached to each of the attachment holes 9.

Further, after connecting the plugs 42 located at each tip of the branch cable 46 extending from the lithium battery 48 inserted in the inner pocket 2a of the clothes 1 to the connector 38 of each of the blower devices 10 in advance, the above. A switch (not shown) arranged on the lithium battery 48 side or in the middle of the cable 46 is turned on.
As a result, the nine blades 24 constituting the fan 20 rotate at high speed, so that the outside air is sent from the outside of the clothes 1 into the blower 10 as shown by the solid arrow in FIG. 2 (A). It can be sucked at a wide angle and in a large amount (large air volume). At this time, since a wide space s based on the distance L is located between the spinner 21 and the top 56 of the outer cylinder 50, a large amount of outside air can be efficiently sucked into the blower 10. At the same time, it is possible to suppress the generation of noise due to the high-speed rotation of each blade 24.

As shown by the arrow of the alternate long and short dash line in FIG. 2A, the large amount of sucked air is supplied from the plurality of air supply holes 18 in the inner cylinder 11 by the nine blades 24 rotating at high speed. A large amount is supplied with a high pressure (static pressure or wind pressure) along the substantially radial direction of the spinner 21 along the gap between the garment 1 and the wearer's underwear h or body h.
As a result, the air supplied along the inside of the garment 1 spreads over the entire back body 8 of the garment 1 as indicated by the arrow of the alternate long and short dash line in FIGS. 1 (A) and 1 (B). Along with being sent, a part of it is also sent to the inside of the sleeves 6 on both sides and the inside of the front view 2. During this period, the sweat generated by the wearer evaporates immediately after being generated by the air that is continuously supplied at high pressure along the inside of the garment 1.

Further, the air containing the evaporation component of the sweat is mainly released to the outside through the gap between the collar 4 of the garment 1 and the wearer's neck. The air is also discharged to the outside from other parts. Further, by sewing in advance a bar or band material that is easily plastically deformed along the inside of the collar 4 of the garment 1, a part of the collar 4 and a part of the wearer's neck side can be formed. A space for exhaust may be arranged in advance between the two.
According to the blower device 10 described above, the effects (1) to (3) can be surely obtained.

Further, according to the air-conditioned clothes 1 in which the blower 10 is attached to the pair of the mounting holes 9, the effects (1) to (3) can be surely obtained, so that the wearer of the clothes 1 is required to perform the work. It has the effect (4) that makes it easy to perform the above efficiently, comfortably and safely.
Further, since the inner diameter of the mounting hole 9 of the air-conditioning garment 1 and the thread diameter of the double-threaded screw 13 in the inner cylinder 11 of the blower 10 may be substantially the same, the blower 10 can be attached to the air-conditioning garment 1. It can be easily removed not only when installing but also when washing.

Hereinafter, the blower device 10 of the embodiment according to the present invention for the purpose of confirming the effect (1) and the blower device (commercially available product) of two comparative examples will be described.

(Note: L in the unit of air volume in Table 2 indicates liter)

According to Tables 1 and 2, the wind speed of the blower 10 of the embodiment is higher than that of the blower of Comparative Examples 1 and 2 even though a relatively low electric power is applied between the measurement positions A and B. Although the wind speed decreased slightly, the wind speed increased between the measurement positions B and C, and the wind speeds at the measurement positions B and C were considerably faster than those at the same positions in Comparative Examples 1 and 2. Further, regarding the air volume, the blower device 10 of the example was the same as that of Comparative Example 1 at the measurement position A, but showed a clearly larger air volume than that of Comparative Examples 1 and 2 at the measured value C.
According to the above results, the blower 10 of the embodiment uses the fan 20 having the blades 24, so that the fan 20 is along a long and wide gap between the inside of the garment 1 and the wearer's body h. Therefore, it was found that the air sucked from the outside can be uniformly blown by a relatively high wind speed and a large amount of air.

Therefore, it was possible to confirm that the blower device 10 of the embodiment has the effect (1).
As shown in Table 1, the blade 24 was able to exhibit the above-mentioned excellent effect (1) as compared with the blower of Comparative Examples 1 and 2. It is presumed that the inclination angle θ3 of is one of the major factors.
