  Although the structure of a general air-conditioning garment is disclosed in Patent Document 1, the disk-type air blower shown in this document has a disk-like shape and prevents the air blower from protruding outward from the clothes. It has a structure in which a flat blower is attached to clothes so that the rotating shaft of the rotary blade is positioned in the horizontal direction.

  However, since it may feel uncomfortable that the wind from the blower directly hits the wearer's body, Patent Document 2 discloses a blower that blows parallel wind parallel to the wearer's body. An air-conditioning garment is disclosed.

  The air blower used in the air-conditioning garment disclosed in the above-mentioned Patent Document 2 has a front surface of the rotating blades that send air to the rotating shaft of the rotating blades in order to avoid the air directly hitting the wearer's back. The fan guard is provided vertically, and the wind from the blower is shielded by the fan guard.

  However, such a structure causes the fan guard to reduce the speed of the air from the rotating blades, lowers the air circulation speed in the clothes, and causes a problem that the cooling effect is impaired. Further, in the disk-type blower, the rotation axis is arranged in a direction orthogonal to the wearer's back, so that the conventional air-conditioning clothing cannot create a directional airflow. For this reason, the air pressure inside the clothes is increased, and the entire air-conditioning clothes including the sleeves are inflated, resulting in a problem of obstructing the operation of the worker.

  Therefore, the object of the present invention is to allow air to flow smoothly from the blower device arranged at the lower inside of the back part of the clothing to the air passage to the collar of the clothing, enhancing the cooling effect and expanding the entire air-conditioned clothing. It is in providing the air-conditioning clothing which can prevent doing.

  In order to achieve the above object, an air-conditioning garment according to the present invention includes a garment, an air intake opening opened outside the garment, an air exhaust opening opened inside the garment, the air intake and the air exhaust. An air-conditioning garment having a blade disposed between the outlet and a driving unit that drives the blade, and blows outside air into the clothing. When the user wears the blade, the rotating shaft of the blade is positioned in an upright direction, and the air discharge port opens upward.

  In order to achieve the above object, the bracket of the present invention includes an air intake port for taking in air outside the garment, an air exhaust port for exhausting air inside the garment, the air intake port and the air exhaust port. And a blower bracket having a driving unit for driving the blade, and when the user wears the clothes, the air intake port is downward and the air discharge port is upward. It is possible to position in a state where the rotating shaft of the blade is erected in the vertical direction.

  According to the air conditioner clothing or the fixing device of the blower of the present invention, the fixing device can hold the blower so that the rotating shaft of the rotary blades stands up and down, and the blowing direction of the blower is determined by the wearer. The air in the garment can be efficiently replaced by matching the air blowing direction with the air blowing path formed from the lower part of the garment to the collar part.

The air discharge port 3 b at the upper end of the fan 3 is fixed so as to be positioned between the inner surface of the back portion 2 a of the jacket 2 and the water retention sheet 6.

  On the inner surface of the lower part of the back portion 2a of the jacket 2, there are left and right fan fixtures 4 as positioning portions of the fans 3. The fan fixture 4 is a restraining cloth that fixes the front and rear side surfaces of the fan 3. 4a and a tension belt 4b that lifts the upper end of the restraining cloth 4a on the wearer side. An upper end 4c of the tension belt 4b is fixed to the shoulder portion of the jacket 2, and a clip 4d is attached to the lower end to fix a partial upper end of the restraining cloth 4a.

  Moreover, the fastener 5 for fixing the water retention sheet | seat 6 mentioned later to the back surface of the jacket 2 is comprised from the clip 5b fixed to the belt 5a and its one end. The other end of the belt 5a is fixed to the back surface of the back portion 2a of the jacket 2 by sewing so that the fasteners 5A and 5B are located on the upper left and right, and the fasteners 5C and 5D are located on the lower left and right.

  The water-retaining sheet 6 of the present embodiment is made of a material having excellent water absorption, for example, made of polyester, specifically, the product name “Shake and Cool” US Coolcore It is preferable to use a towel material having a multilayer structure having a water retention layer / evaporation layer. The upper and left ends 6a and 6b of the water retaining sheet 6 are fixed to the clips 5b of the fasteners 5A and 5B, and the lower left and right ends 6c and 6d are fixed to the clips 5b of the fasteners 5C and 5D. Can be set.

  Next, the structure of the fixture 4 of the fan 3 will be described in detail with reference to FIG. The restraint piece 4a of the fixture 4 is composed of a first piece portion 4a1 and a second piece portion 4a2 that stand up together, and a third piece portion 4a3 portion that horizontally connects these portions at the lower end.

  The restraining cloth 4a also serves as a reinforcing material for the jacket 2 around the fixing device of the fan 3, and the first piece 4a1 and the third piece 4a3 are stacked on the inner surface of the lower part of the back portion 2a of the jacket 2. Then, it is fixed by sewing. The third piece 4 a 3 functions as a reinforcing material that supports the weight 3 of the fan 3 by opening the mounting hole of the fan 3 together with the fabric of the jacket 2.

  Inside the cylindrical main body of the fan 3, an electric motor 3d that is driven by electric power from the battery 3c, which is a driving unit, is disposed, and a blade 3e that is coupled to the motor 3d is disposed below.

  Moreover, as for the 2nd piece part 4a2 located in the wearer X side among the restraint cloth 4a, a lower end is fixed to the 3rd piece part 4a3 part, and an upper end is a free end. As described above, the upper portion of the third piece 4a2 is fixed to the clip 4d at the lower end of the tension belt 4b, and the third piece 4a2 is suspended by the tension belt 4b. The part 4a3 is positioned in a horizontal state.

  Further, the restraining cloth 4a has a fixing belt 4e that restrains the outer peripheral surface of the main body of the fan 3. The fixing belt 4e is attached to the second piece 4a2, and the fan 3 is attached to the second piece 4a2. It is fixed together.

  Next, the effect of the air-conditioning clothing of this embodiment will be described with reference to FIG. FIG. 3 is a rear perspective view of the air-conditioning clothing with the wearer wearing the air-conditioning clothing.

  When the wearer X wears the jacket 2, the upper end 4d of the tension belt 4b is pulled up by the shoulder of the wearer X, and as a result, the tension belt 4b pulls the third piece 4a3 upward. And since the air intake 3a of the fan 3 fixed to the 3rd piece part 4a3 will be in a horizontal state, the air intake 3a will face downward and the air exhaust 3b will face upward, and an electric motor The drive shaft 3x stands up. Here, standing refers to being arranged in a vertical direction along a plane parallel to the back portion 2a of the jacket 2, and includes not only vertical but also tilting to a certain degree around the periphery.

  In this state, when the fan 3 located on the waist of the wearer X is driven, the outside air of the jacket 2 is taken in from the air intake port 3a, and wind parallel to the back of the wearer X is sent out from the air discharge port 3b. This air inflates the back part 2a of the jacket 2 and forms the air passage 7 between the back of the wearer X.

  Then, the air from the fan 3 passes through the air passage 7, passes through the tunnel 2 g formed by the bridge band 2 f in the collar 2 d of the jacket 2, and escapes from the neck of the wearer X. At this time, moisture contained in the surface 6e of the water retention sheet 6 facing the air passage 7 is volatilized, depriving the heat of vaporization, and lowering the temperature of the water retention sheet 6 and thus the inside of the jacket 2.

  When the jacket 2 is inflated with air pressure in a state where the four sides 6a to 6d are fixed with the fasteners 5A to 5D, the distance between the fasteners 5A to 5D also increases, so that the water retaining sheet 6 is also tensioned in all directions. It is stretched in a tensioned state. For this reason, the surface which touches a wind becomes large and can use vaporization heat efficiently.

  As described above, since the fan 3 stands up and down, the momentum is reduced by matching the air blowing path 7 formed from the lower side to the upper side of the jacket 2 with the air blowing direction by the blades 3e of the fan 3. The wind can be sent smoothly without escaping.

  For this reason, according to this embodiment, the circulation of the air of the ventilation path 7 can be made smooth, and the cooling effect by the vaporization heat of the moisturizing sheet 6 can be increased and the inside of the jacket 2 can be cooled more efficiently. Can do. In addition, the air blown into the jacket 2 forms the air blowing path 7, and has straight advanceability so as to escape from the neck 2 d, so that the jacket 2 is difficult to expand and hinders the movement of the wearing worker. Can be prevented.

In the present embodiment, the fan 3 has a vertically long cylindrical shape. However, the fan shaft 3x of the fan blades is erected in the vertical direction, and the fan path 7 is formed in the vertical direction of the clothing. It is only necessary that the air blowing directions by the blades 3e coincide with each other, and various fans can be selected. Further, although the air passage for discharging the air exhausted by the fan 3 from the collar of the jacket 2 is configured, a special exhaust hole can be provided in the jacket 2.
