Description

[Technical Field]

[0001] The present disclosure relates to a blower device having a Peltier element and a fan. [Background technology]

[0002] Patent Document 1, which is a conventional technique, discloses an air conditioning unit 100 that uses a Peltier element 117 to locally cool a body 200 . FIG. 15 is a cross-sectional view of the air conditioning unit 100 of Patent Document 1. Patent Document 1 will be described with reference to FIG. The air conditioning unit 100 is attached to clothing 150. The air conditioning unit 100 has a heat insulating pad 130 disposed inside the garment 150 and a fixing pad 140 disposed outside the garment 150 .

[0003] The three protrusions on the fixing pad 140 pass through three small diameter holes in the clothing 150 and are inserted into three recesses in the heat insulating pad 130, and the air conditioning unit 100 is attached to the clothing 150.

[0004] A fan cover 111 is provided on the fixed pad 140, and a heat sink 115 is provided on the fan cover 111. The fan 114 is disposed inside the fan cover 111 and above the heat sink 115.

[0005] The Peltier element 117 is provided below the fixed pad 140, and is arranged at the same position as the clothing 150 in a direction perpendicular to the clothing 150 (hereinafter referred to as the vertical direction). An auxiliary metal plate 119 is provided below the cooling portion of the Peltier element 117, and an extension metal plate 120 is further provided below the auxiliary metal plate 119. The heat (cold temperature) of the cooling portion of the Peltier element 117 is transferred to the extended metal plate 120 through the auxiliary metal plate 119, and the extended metal plate 120 is cooled. When the expanded metal plate 120 comes into close proximity to or contacts the body 200, a localized portion of the body 200 (having approximately the same area as the expanded metal plate 120) is cooled.

[0006] The seat sink 115 is located on the outside of the garment 150 . The heat sink 115 is cooled by the wind (air) blown in the vertical direction (F1) by the fan 114. At this time, the wind (air) from the fan 114 is heated by the heat sink 115. The air heated by the heat sink 115 is bent from the vertical direction (F1) to a horizontal direction (F2) by the heat sink 115. Then, outside the clothing 150, the air heated by the heat sink 115 is discharged to the outside of the fan cover 111 through the exhaust port 113 (F2).

[0007] With this configuration, in Patent Document 1, the air heated by the seat sink 115 is diffused outside the clothing 150 and does not penetrate into the clothing 150. Therefore, Patent Document 1 can efficiently cool the expanded metal plate 120 inside the clothing 150, and can cool localized areas of the body (approximately the same area as the expanded metal plate 120). [Prior art documents] [Patent documents]

[0008] [Patent Document 1] Japanese Patent Publication No. 2021-113371 [Patent Document 2] Patent No. 6200606 Summary of the Invention [Problem to be solved by the invention]

[0009] However, Patent Document 1 cools a localized area of ​​the body (approximately the same area as the expanded metal plate 120), and does not cool the air inside the clothing 150 (the air between the clothing 150 and the body 200), so there is room for improvement.

[0010] Meanwhile, conventional clothing fans (e.g., Patent Document 2) have been widely used in recent years, and they draw air (outside air) from outside the clothing into the clothing to cool the body. However, these clothing fans do not have the function of cooling the air drawn into the clothing. The clothing has a hole with a diameter of, for example, 90 mm, and the clothing fan is inserted into this hole to attach the clothing fan to the clothing. This 90mm diameter hole is the standard size for clothing to mount a clothing fan.

[0011] However, in Patent Document 1, in order to secure the air conditioning unit 100 to the clothing 150, three special small diameter holes must be made in the clothing 150, which makes it difficult to accommodate holes with a standard diameter of 90 mm. The blower device according to one aspect of the present disclosure solves the above-mentioned problems. [Means for solving the problem]

[0012] A blower according to one aspect of the present disclosure includes a Peltier element having a first substrate as a cooling unit and a second substrate as a heating unit, a heat sink provided on the second substrate, a fan, and a heat diffusion member, and is attached to clothing, The first substrate and the heat diffusion member are in contact with each other, and the cold heat of the first substrate is transferred to the heat diffusion member. The diameter of the heat diffusion member is larger than the diameter of the heat sink. The fan blows air from outside the garment into the garment to cool the heat sink. The outer diameter of the fan is larger than the outer diameter of the heat sink. When the fan blows air from outside the garment into the garment, the air comes into contact with the heat diffusion member and is cooled, and the cooled air is taken into the garment. A blower according to another aspect of the present disclosure is an air blower attached to clothing, the air blower comprising: a Peltier element having a first substrate as a cooling unit and a second substrate as a heating unit; a heat sink provided on the second substrate; a first fan; a second fan; and a heat diffusion member; The first substrate and the heat diffusion member are in contact with each other, and the cold heat of the first substrate is transferred to the heat diffusion member. The first fan blows air from outside the garment into the garment, The second fan dissipates heat from the heat sink to the outside of the clothing to cool the heat sink, When the first fan blows air from outside the garment into the garment, the air comes into contact with the heat diffusion member and is cooled, and the cooled air is taken into the garment. [Effects of the Invention]

[0013] In one aspect of the air blowing device of the present disclosure, when air from outside the clothing is blown into the inside of the clothing by a fan, the air comes into contact with a heat diffusion member that is larger than the outer diameter of the heat sink and is cooled, and the cooled air is taken into the inside of the clothing, thereby cooling the entire body. Furthermore, the air blower according to one embodiment of the present disclosure can be easily attached to clothing by being inserted into a hole with a standard diameter of 90 mm.

[0015] Specific embodiments of the present disclosure will be described below. However, more detailed descriptions than necessary may be omitted. For example, detailed descriptions of well-known matters or redundant descriptions of substantially identical configurations may be omitted. This is to avoid unnecessary redundancy in the following description and to facilitate understanding by those skilled in the art. Note that the inventors provide the accompanying drawings and the following description to enable those skilled in the art to fully understand the present disclosure, and are not intended to limit the subject matter described in the claims. In the following description, identical or similar components are designated by the same reference numerals.

[0016] (Embodiment 1) First, the overall configuration of the blower 1 will be described, and then each component will be described in detail.

[0017] (Overall configuration of the blower) The blower device 1 according to the first embodiment of the present disclosure will be outlined below with reference to the drawings.

[0018] Figure 1 is a schematic diagram of a blower 1 attached to clothing 50 in embodiment 1, Figure 2 is a schematic oblique view of the blower 1 in embodiment 1 as seen from the fan 7 side, Figure 3 is a schematic oblique view of the blower 1 in embodiment 1 as seen from the heat diffusion member 13 side, Figure 4 is a schematic exploded oblique view of the blower 1 in embodiment 1, and Figure 5 is a schematic side view of the main body 3 of the blower 1 in embodiment 1.

[0019] Here, with respect to when clothing 50 is worn on a person's body, the side of blower 1 that is away from the person is defined as the upper side (outside), and the side that is closer to the person is defined as the lower side (inside).

[0020] 1, clothing 50 has two air blowers 1 provided below half of clothing 50. Clothing 50 is the same as the clothing used in Patent Document 2. The garment 50 is provided with a reinforcing member 40 made of thick fabric at the position where the two air blowers 1 are arranged to prevent wrinkles.

[0021] Two holes 53 are provided in the garment 50 and the reinforcing member 40 in order to fix the two air blowers 1 to the garment 50. The air blowers 1 are inserted into these two holes and fixed to the garment 50. Generally, the diameter of these two holes is 90 mm, which is the standard size for clothing 50 to which air blower 1 is attached.

[0022] As shown in FIG. 2-4, the blower 1 has a main body 3 and a mounting ring 4. The mounting ring 4 is screw-type. The body portion 3 has a first flange 20 and the mounting ring 4 has a second flange 21 . The garment 50 is sandwiched between the first flange 20 and the second flange 21 . By rotating the attachment ring 4, the clothing 50 is sandwiched between the first flange 20 and the second flange 21, and the air blower 1 is fixed to the clothing 50 (see FIG. 7).

[0023] As shown in Figure 5, a Peltier element 9 is arranged on the underside of the main body 3, and has a first substrate 10 which is a cooling part, a second substrate 12 which is a heating part, and a semiconductor 11 located between the first substrate 10 and the second substrate 12.

[0024] A heat diffusion member 13 is disposed below the first substrate 10 so as to be in contact with the first substrate 10. The cold and heat of the first substrate 10 is transferred to the heat diffusion member 13. The first substrate 10 and the heat diffusion member 13 are disposed inside the garment 50.

[0025] A heat sink 8 is disposed above the second substrate 12 so as to be in contact with the second substrate 12 . A fan 7 is disposed above the heat sink 8, and there is a gap between the heat sink 8 and the fan 7. The fan 7 blows air from outside the clothing 50 into the clothing 50 to cool the heat sink 8 . The heat diffusion member 13 is preferably circular, and the heat sink 8 is preferably circular or rectangular.

[0026] As shown in FIG. 5-6, when a person views the main body 3 from above, the area (in plan view) of the heat diffusion member 13 is larger than the area (in plan view) of the heat sink 8. That is, the diameter D3 of the outer periphery of the heat diffusion member 13 is larger than the diameter D2 of the outer periphery of the heat sink 8. Here, the outer diameter D3 of the heat diffusion member 13 refers to the diameter of an imaginary circle that passes through the tip of the outer edge of the heat diffusion member 13 when viewed in a plane. In the case of Figures 5-6, the heat diffusion member 13 is a circle, so the outer diameter D3 of the heat diffusion member 13 is the diameter of that circle. The heat diffusion member 13 may have an elliptical, rectangular, polygonal or other shape. The diameter D2 of the outer periphery of the heat sink 8 is the diameter of an imaginary circle that passes through the tip of the heat sink 8 when viewed from above. The heat sink 8 may have an oval, rectangular, polygonal or other shape.

[0027] The diameter D1 of the outer periphery of the fan 7 is larger than the diameter D2 of the outer periphery of the heat sink 8 (Peltier element 9). Here, the diameter D1 of the outer periphery of the fan 7 refers to the diameter of an imaginary circle that passes through the tip of the fan 7 when viewed from above. In other words, the relationship is diameter D3>diameter D1>diameter D2.

[0028] As will be described in more detail later, the diameter D3 of the outer periphery of the heat diffusion member 13 is larger than the diameter D2 of the outer periphery of the heat sink 8, so that the air sent into the inside of the clothing 50 by the fan 7 hits the heat diffusion member 13 at a point outside the outer periphery of the heat sink 8. Therefore, when the fan 7 sends air from outside the clothes 50 into the clothes 50, the air comes into contact with the heat diffusion member 13 and is cooled, and the cooled air is taken into the clothes 50, thereby cooling the whole of the person's body.

[0029] Next, each component will be described in detail.

[0030] (Main body) As shown in FIG. 5, the main body 3 has, in order from the top, a top surface 27, a side surface 28, and a bottom surface 29.

[0031] As shown in FIGS. 2, 4 and 5, the upper surface 27 is provided with an air intake 16. The air intake 16 is formed by a plurality of air intake frames 43 and is a ventilation port that sends air from outside the garment 50 into the interior of the garment 50.

[0032] A first engagement member 17 is provided below the intake port 16. In the cases of Figures 2, 4 and 5, the first engagement member 17 is a male screw. A first flange 20 is provided on the underside of the first engagement member 17 .

[0033] The main body 3 has a Peltier element unit 14 having a heat sink 8 and a Peltier element 9, which will be described later.

[0034] FIG. 6 is a schematic bottom view of the main body 3 in the first embodiment. As shown in FIG. 6, the heat diffusion member 13 is disposed on the bottom surface 29. The heat diffusion member 13 has a flat surface 41 in the center, and a plurality of extension frames 42 connected to the flat surface 41 outside the flat surface 41 in the center. The flat surface 41 and the first substrate 10 are in contact with each other, and the cold heat (cold temperature heat) of the first substrate 10 is transferred to the flat surface 41. Then, the cold heat (cold temperature heat) of the flat surface 41 is transferred to the extension frame 42. The heat diffusion member 13 (flat surface 41 and extension frame 42) is preferably made of a metal with excellent thermal conductivity, and in particular, an aluminum alloy (aluminum). Considering the ease with which the wind from the fan 7 is received, it is preferable that the width of the cross section of the extension frame 42 be greater than the height of the cross section of the extension frame 42 . The height of the cross section of the extension frame 42 may be greater than the width of the cross section of the extension frame 42 .

[0035] An opening 15 is provided between two adjacent extension frames 42 of the plurality of extension frames 42 . When the fan 7 blows air from outside the garment 50 into the garment 50 through the opening 15, the air comes into contact with the extension frame 42 and is cooled, and the cooled air is taken into the garment 50, thereby cooling the entire human body. As mentioned above, the relationship is diameter D3>diameter D1>diameter D2.

[0036] (Mounting ring) As shown in FIGS. 2 and 4, the attachment ring 4 is disposed on the outside of the main body 3 and rotates to sandwich the garment 50 between the main body 3 and the attachment ring 4. The mounting ring 4 has a mounting ring body 22 and a second flange 21 on the lower side of the mounting ring body 22. A second engagement member 18 is provided on the inside of the attachment ring body 22. In the case of Fig. 4, the second engagement member 18 is a female screw.

[0037] The male thread of the first engaging member 17 and the female thread of the second engaging member 18 are engaged with each other, and the first engaging member 17 and the second engaging member 18 are rotated relative to each other, causing the first engaging member 17 and the second engaging member 18 to move in the direction of contact. As a result, the clothing 50 is sandwiched between the first flange 20 of the main body 3 and the second flange 21 of the attachment ring 4 , and the air blower 1 is fixed to the clothing 50 . The first engaging member 17 may be a female screw, and the second engaging member 18 may be a male screw.

[0038] (Peltier element unit) FIG. 8 is a schematic cross-sectional view of the blower 1 according to the first embodiment. As shown in FIGS. 5 and 8, the Peltier element unit 14 has a heat sink 8 and a Peltier element 9 below the heat sink 8.

[0039] The heat sink 8 is a heat exchange part that comes into contact with the second substrate 12, which is the heating part of the Peltier element 9, and releases heat from the second substrate 12. The heat sink 8 is preferably made of a metal such as an aluminum alloy (aluminum) that has good thermal conductivity.

[0040] The Peltier element 9 has a first substrate 10 which is a cooling portion, a second substrate 12 which is a heating portion, and a semiconductor 11 between the first substrate 10 and the second substrate 12. A first lead portion (not shown) is connected to one side of the semiconductor 11, and a second lead portion (not shown) is connected to the other side of the semiconductor 11. When a positive voltage is applied to the first lead portion and a negative voltage is applied to the second lead portion, the first substrate 10 is cooled and the second substrate 12 is heated. The heat from the heated second substrate 12 is transferred to the heat sink 8, and the transferred heat is dissipated by the heat sink 8.

[0041] The Peltier element unit 14 is circular, and the heat sink 8 and the Peltier element 9 are also circular. The area of ​​the heat sink 8 is greater than or equal to the area of ​​the Peltier element 9 . The shape of the heat sink 8 and / or the shape of the Peltier element 9 may be rectangular, and is not particularly limited.

[0042] (Combination of main body and mounting ring) FIG. 7 is a schematic perspective view showing a state in which the air blower 1 is attached to clothing 50 in the first embodiment. As shown in FIG. 7, most of the main body 3 of the air blower 1 protrudes from the clothing 50 when the air blower 1 is attached to the clothing 50 . 8, the air blower 1 is fixed to the clothing 50 by sandwiching the clothing 50 between the first flange 20 of the main body 3 and the second flange 21 of the attachment ring 4. At this time, the reinforcing member 40 (not shown) is also sandwiched between the first flange 20 and the second flange 21.

[0043] When the mounting ring 4 is rotated, the male thread of the first engaging member 17 of the main body 3 and the female thread of the second engaging member 18 of the mounting ring 4 engage and move closer together, and the clothing 50 is sandwiched between the first flange 20 and the second flange 21, thereby fixing the air blower 1 in place.

[0044] The blower 1 has a motor 6 provided on an upper surface 27, and a fan 7 connected to the motor 6 below the motor 6. A Peltier element unit 14 is provided below the fan 7, and there is an air gap between the fan 7 and the Peltier element unit 14.

[0045] A heat diffusion member 13 is provided below the first substrate 10 and the first flange 20. The heat diffusion member 13 is provided with a cooling unit holder 35 for fixing the Peltier element unit 14 thereto.

[0046] The cold heat (cold temperature heat) of the first substrate 10 is transferred to the heat diffusion member 13, and the cold heat (cold temperature heat) spreads over the entire surface of the heat diffusion member 13, thereby cooling the entire surface of the heat diffusion member 13. It is not necessary for most of the main body 3 of the air blower 1 to protrude from the clothing 50.

[0047] (wind flow) Explain the wind flow. There are three wind currents: F1, F2, and F3.

[0048] (1) Explain the wind flow in one eye (air F1). The first wind flow is the flow taken in through the intake port 16 (air F1). FIG. 11 is a schematic perspective view of the heat sink 8 in the first embodiment. 11, the heat sink 8 has a plurality of fins 48 in the shape of a substantially rectangular prism and a circular, plate-like main body plate 47. The cross section of the plurality of fins 48 is preferably rectangular (square, oblong), triangular, polygonal, or the like.

[0049] As shown in FIG. 8, when the fan 7 is rotated by the motor 6, air F1 outside the blower 1 passes through the intake port 16 and enters the interior of the blower 1.

[0050] (2) Explain the wind flow in the second eye (air F2). As shown in FIG. 8, the invading air F2 is divided into two air streams F2A and F2B. The air F2A hits the side surfaces of the fins 48 of the heat sink 8 and the main body plate 47 and is heated, and the air F2A cools the heat sink 8. The heated air F2A passes near the outside of the outer periphery of the heat sink 8. The air F2B passes a short distance from the heat sink 8 at the same temperature as the outside air.

[0051] (3) Explain the third wind flow (air F3). As a premise, it is preferable that the flat surface 41 of the heat diffusion member 13 and the body 51 are not in contact with each other. The air F2B, which has the same temperature as the outside air, is cooled by the extension frame 42 and enters the inside of the garment 50. The heated air F2A also enters the interior of the garment 50. A portion (near the heat sink 8) of the air F2B that has been cooled by the extension frame 42 and entered the garment 50 comes into contact with the heated air F2A that has entered the garment 50, and the heated air F2A is cooled and neutralized. As a result, the body 51 is prevented from being heated by the neutralized air F2A.

[0052] Another part of the air F2B cooled by the extension frame 42 and entering the garment 50, air F3 (at a location away from the heat sink 8), passes between the garment 50 and the body 51 and spreads over the entire body 51. As a result, the entire body 51 can be cooled.

[0053] Furthermore, the cold cooled by the first substrate 10, which is the cooling portion, is transferred to the flat surface 41, thereby cooling the flat surface 41. Then, the cooled air F4 is released from the flat surface 41. A portion of the air F4 comes into contact with the heated air F2A, and the heated air F2A is cooled and neutralized, thereby preventing the body 51 from being heated by the neutralized air F2A. Another part of the air F4 becomes air F3, and the air F3 passes between the clothes 50 and the body 51 and spreads over the entire body 51. As a result, the entire body 51 can be cooled.

[0054] According to the above embodiment, the fan 7 draws air from outside the garment 50 into the garment 50 through the openings 15 of the extension frame 42. The air drawn inside is then cooled by the extension frame 42 and / or the flat surface 41 of the heat diffusion member 13, thereby cooling the entire body 51. As a result, the air blower 1 sends cooled air F3 to the space between the body 51 and the clothes 50, so that the cooled air F3 can cool the entire body 51. Furthermore, the air blower 1 can be easily attached to the clothing 50 by inserting it into a hole with a standard diameter of 90 mm.

[0055] In the above embodiment, the first engaging member 17 and the second engaging member 18 are rotated relative to each other to bring the first engaging member 17 and the second engaging member 18 close to each other and engage with each other. However, the first engaging member 17 and the second engaging member 18 may be engaged with each other without rotating the first engaging member 17 and the second engaging member 18 relative to each other.

[0056] (power control) FIG. 14 is a schematic diagram showing the electrical system of the blower 1 in the first embodiment. As shown in Figure 14, the electrical system of the blower 1 includes a mobile battery 65, a remote control 70, one blower 1, 30, 80 (hereinafter referred to as the left blower), and the other blower 1, 30, 80 (hereinafter referred to as the right blower). A power cord 61 is provided between the mobile battery 65 and the remote control 70 to electrically connect them.

[0057] A first power supply cord 62 is provided between the remote control 70 and the right-side blower 1, 30, 80 for electrical connection. The first power supply cord 62 supplies power to the fan 7 and Peltier element 9 of the right-side blower 1.

[0058] A second power supply cord 63 is provided between the remote control 70 and the left-side blower 1, 30, 80 for electrical connection. The second power supply cord 63 supplies power to the fan 7 and Peltier element 9 of the left-side blower 1. The power cord 61 is preferably a USB cable, a Type-A cable, a Type-C cable, or the like, which has good connectivity with the mobile battery 65 .

[0059] The remote control 70 has a power button 71 for the fan 7 and a power button 75 for the Peltier element 9 .

[0060] The remote control 70 also has a first fan lamp (weak) 72, a second fan lamp (medium) 73, a third fan lamp (strong) 74, a first Peltier lamp (weak) 76, a second Peltier lamp (medium) 77, and a third Peltier lamp (strong) 78.

[0061] The remote control 70 controls the fan 7 and the Peltier element 9 independently. First, the control of the fan 7 will be described.

[0062] When the power button 71 of the fan 7 is pressed once, the first fan lamp (weak) 72 lights up and the fan 7 rotates at the weakest wind speed. When the power button 71 of the fan 7 is pressed once again, the illumination switches from the first fan lamp (weak) 72 to the second fan lamp (medium) 73, and the fan 7 rotates at the second strongest wind speed. When the power button 71 of the fan 7 is pressed once again, the illumination switches from the second fan lamp (medium) 73 to the third fan lamp (strong) 74, and the fan 7 rotates at the strongest wind speed. When the power button 71 of the fan 7 is pressed once again, all of the first lamp 72 to the third fan lamp 74 turn off and the fan 7 stops rotating.

[0063] Next, the control of the Peltier element 9 will be described. When the power button 75 of the Peltier element 9 is pressed once, the first Peltier lamp (weak) 76 is turned on and the Peltier element 9 performs the weakest cooling. When the power button 75 of the Peltier element 9 is pressed once again, the lighting is switched from the first Peltier lamp (weak) 76 to the second Peltier lamp (medium) 77, and the Peltier element 9 performs the second strongest cooling. When the power button 75 of the Peltier element 9 is pressed once again, the lighting is switched from the second Peltier lamp (medium) 77 to the third Peltier lamp (strong) 78, and the Peltier element 9 performs the strongest cooling. When the power button 75 of the Peltier element 9 is pressed once again, all of the first Peltier lamp (weak) 76 to the third Peltier lamp (strong) 78 are turned off and the cooling of the Peltier element 9 stops.

[0064] When the power of the mobile battery 65 is running low, one of the above lamps may flash to prompt the user to replace the mobile battery 65. Although the embodiment shown in FIG. 8 has been described in which the flat surface 41 of the heat diffusion member 13 is not in contact with the body 51, the flat surface 41 may be in contact with the body 51.

[0065] (Embodiment 2) The air blower 30 of embodiment 2 has a first housing 31 and a second housing 32 which are separate bodies, and the air blower 30 is attached to the clothing 50 by rotating the first housing 31 and the second housing 32 relative to each other, like turning a screw.

[0066] FIG. 9 is a schematic cross-sectional view of the blower device 30 according to the second embodiment. In the first housing 31, the heat diffusion member 13, the Peltier element 9, and the heat sink 8 are arranged in this order with the lower side of the first housing 31 as a reference. The first housing 31 also has a cooling unit holder 35 and a third flange 36 . The second housing 32 includes the motor 6 , the fan 7 , and a fourth flange 37 .

[0067] The first housing 31 has a third engagement member 33 (male thread in FIG. 9) on the outer periphery, and the second housing 32 has a fourth engagement member 34 (female thread in FIG. 9) on the inner periphery. When the first housing 31 and the second housing 32 rotate relative to each other, the third engaging member 33 and the fourth engaging member 34 engage with each other.

[0068] As a result, the clothing 50 is sandwiched between the third flange 36 of the first housing 31 and the fourth flange 37 of the second housing 32, and the air blower 30 is fixed to the clothing 50. At this time, there is a gap between the heat sink 8 and the fan 7 . The above-mentioned male and female threads may be reversed.

[0069] The cooling unit holder 35 is provided on the heat diffusion member 13 . The Peltier element unit 14 and the cooling unit holder 35 are engaged with each other, whereby the Peltier element 9 is fixed to the heat diffusion member 13 (first housing 31). The above three air flows are the same as those in the first embodiment, and therefore the description thereof will be omitted.

[0070] According to the above embodiment, the air blower 30 draws air (outside air) outside the clothing 50 into the inside of the clothing 50 through the opening 15, and cools the air drawn in by the extension frame 42 and / or flat surface 41 of the heat diffusion member 13, thereby cooling the entire body 51. Furthermore, the air blower 30 can be easily attached to clothing by being inserted into a hole with a standard diameter of 90 mm. The third engaging member 33 and the fourth engaging member 34 were rotated relative to each other to bring the third engaging member 33 and the fourth engaging member 34 close to each other and engage with each other. However, the third engaging member 33 and the fourth engaging member 34 may be engaged with each other without rotating the third engaging member 33 and the fourth engaging member 34 relative to each other.

[0071] (Embodiment 3) The blower device 80 of embodiment 3 has a third housing 81 and a fourth housing 82 which are separate bodies, and the blower device 80 is attached to the clothing 50 by rotating the third housing 81 and the fourth housing 82 relative to each other, like turning a screw. The air blower 80 of the third embodiment has a configuration in which the vertical (outside, inside) arrangement relationship between the fan 7 and the Peltier element unit 14 of the air blower 30 of the second embodiment is reversed.

[0072] FIG. 10 is a schematic cross-sectional view of a blower device 80 according to the third embodiment. The third housing 81 includes the motor 6 , the fan 7 , and a fifth flange 85 . In the fourth housing 82, the heat sink 8, the Peltier element 9, and the heat diffusion member 13 are arranged in this order with the lower side of the fourth housing 82 as the base. The fourth housing 82 also has a cooling unit holder 35 and a sixth flange 86 .

[0073] The third housing 81 has a fifth engagement member 83 (female thread in FIG. 10) on its inner periphery, and the fourth housing 82 has a sixth engagement member 84 (male thread in FIG. 10) on its outer periphery. When the third housing 81 and the fourth housing 82 rotate relative to each other, the fifth engaging member 83 and the sixth engaging member 84 engage with each other.

[0074] As a result, the clothing 50 is sandwiched between the fifth flange 85 of the third housing 81 and the sixth flange 86 of the fourth housing 82 , and the air blower 80 is fixed to the clothing 50 . At this time, there is a gap between the heat sink 8 and the fan 7 . The above-mentioned male and female threads may be reversed.

[0075] The cooling unit holder 35 is provided on the heat diffusion member 13 . The Peltier element unit 14 and the cooling unit holder 35 are engaged with each other, whereby the Peltier element unit 14 is fixed to the heat diffusion member 13 (fourth housing 82).

[0076] (wind flow) Explain the wind flow. There are three wind currents: F1, F2, and F3.

[0077] (1) Explain the wind flow in one eye (air F1). One wind flow is the flow (air F1) taken in through opening 15.

[0078] When the fan 7 is rotated by the motor 6 provided in the third housing 81, air F1 outside the blower 1 passes through the opening 15 and enters the interior of the blower 80.

[0079] (2) Explain the wind flow in the second eye (air F2). As shown in FIG. 10, the invading air F2 is divided into two air streams F2A and F2B. Air F2A is air heated by heat sink 8 and drawn into clothing 50 by fan 7. The air F2A is cooled and neutralized by the air F1 cooled by the flat surface 41 and a portion of the air F1 cooled by the extension frame 42. As a result, the body 51 is prevented from being heated by the neutralized air F2A.

[0080] The air F2B is air cooled by the extension frame 42 and passes through a location a short distance away from the heat sink 8.

[0081] (3) Explain the third wind flow (air F3). The neutralized air F2A is taken into the interior of the garment 50. In addition, the air F2B cooled by the extension frame 42 is also taken into the garment 50. The neutralized air F2A is cooled by a portion of the cooled air F2B to form air F3. Another part of the cooled air F2B becomes air F3. The air F3 passes between the clothing 50 and the body 51 and spreads over the entire body 51. As a result, the entire body 51 can be cooled.

[0082] According to the above embodiment, the air F1 taken in through the opening 15 of the extension frame 42 is cooled, and the cooled air F1 becomes air F3 and is taken into the inside of the garment 50. As a result, the air blower 1 sends cooled air F3 to the space between the body 51 and the clothes 50, so that the cooled air F3 can cool the entire body 51. Furthermore, the air blower 1 can be easily attached to the clothing 50 by inserting it into a hole with a standard diameter of 90 mm.

[0083] In the above embodiment, the fifth engaging member 83 and the sixth engaging member 84 are rotated relative to each other to bring the fifth engaging member 83 and the sixth engaging member 84 close to each other and engage with each other. However, the fifth engaging member 83 and the sixth engaging member 84 may be engaged with each other without rotating the fifth engaging member 83 and the sixth engaging member 84 relative to each other. In the above embodiment, the Peltier element unit 14 is disposed below the heat diffusion member 13 , but the Peltier element unit 14 may be disposed above the heat diffusion member 13 . In this case, the Peltier element 9 and the heat sink 8 are arranged in this order on the heat diffusion member 13. The heat sink 8 is located on the uppermost side (outside) of the blower 80.

[0084] (Embodiment 4) FIG. 12 is a schematic perspective view of the heat sink 8 according to the fourth embodiment. As shown in Fig. 12, the heat sink 8 has a circular, plate-like main body plate 47 and a plurality of fins 48. The plurality of fins 48 are arranged radially from the center of the circular main body plate 47. The plurality of fins 48 are rectangular in shape. In Fig. 12, the rectangular shape is longer in the radial direction.

[0085] According to the above embodiment, since the plurality of fins 48 are arranged radially on the main body plate 47, the air heated by the plurality of fins 48 does not spread much from the outer periphery of the main body plate 47, but passes only around the main body plate 47. Therefore, the air heated by the plurality of fins 48 can be neutralized with the air cooled by the extension frame 42 around the main body plate 47 .

[0086] (Embodiment 5) FIG. 13 is a schematic diagram of the air blower 1 attached to clothing 90 in the fifth embodiment. As shown in FIG. 13, one air blower 1 is provided on the back side of the garment 90, in the center in the left-right direction and slightly below the center in the up-down direction. Therefore, the clothing 90 is provided with a hole 53 and a reinforcing member 40 for attaching the air blower 1.

[0087] Since the air blower 1 in FIG. 1 is placed at the waist level of a person, the air blower 1 cools the waist. For people who suffer from lower back pain, it is not good for their lower back to get cold. Therefore, in the fifth embodiment, the blower 1 is placed at a position away from the waist. In order to cool the entire body 51, one air blower 1 is provided in the center of the clothing 90 in the left-right direction and slightly below the center in the up-down direction. According to the above embodiment, the garment 90 can cool the entire body 51 without cooling the waist. The clothing 90 can also be used with the air blowers 30 and 80 instead of the air blower 1.

[0088] (Embodiment 6) In the blower 1 of the first embodiment shown in FIG. 8, the fan 7 is disposed above (outside) the heat sink 8.

[0089] On the other hand, in the air blower 250 of the sixth embodiment, the fan 7 is disposed below (inside) the heat diffusion member 13, and the air outside the clothes is taken into the inside of the clothes 50 by the fan 7. FIG. 16 is a schematic cross-sectional view of a blower 250 according to the sixth embodiment. As shown in FIG. 16, the fan 7 is disposed below the heat diffusion member 13, and the heat diffusion member 13 and the fan 7 are disposed inside the clothing 50. The extension frame 42 and the flat surface 41 of the heat diffusion member 13 are in the same plane. The heat sink 8 is preferably located on the outside of the garment 50 so that it is as cool as possible. A first fan cover 320 is provided below the heat diffusion member 13 so as to cover the fan 7 . The first fan cover 320 is provided with a first fan cover opening 321 . The configuration other than that described above is basically the same as that of the blower device 1 in FIG.

[0090] According to the above embodiment, the fan 7 draws air from outside the clothing 50 into the clothing 50 through the openings 15 of the extension frame 42 (air F2). The air drawn in is then cooled by the extension frame 42 and / or the flat surface 41 of the heat diffusion member 13 (air F4), and the cooled air is released to the outside of the first fan cover 320 (air F21). The air released to the outside of the first fan cover 320 can cool the entire body 51 (air F3). The configuration of the sixth embodiment may be applied to the first housing 31 of FIG.

[0091] (Embodiment 7) The blower 300 of the seventh embodiment includes a first fan 301 and a second fan 302, and a Peltier element unit 14 is provided between the first fan 301 and the second fan 302. The blower device 300 has a configuration in which the first fan 301 blows air from outside the clothing 50 into the inside of the clothing 50, and the second fan 302 releases heat from the heat sink 8 to the outside of the clothing 50, thereby cooling the heat sink 8.

[0092] FIG. 17 is a schematic cross-sectional view of a blower 300 according to the seventh embodiment. As shown in Figure 17, the main body 303 is provided with, in order from the bottom of the blower device 300, a first fan cover 320, a first fan 301, a heat diffusion member 13, a Peltier element unit 14, a second fan 302, and an air intake frame 43. The first fan 301 is rotated by a first motor 6a, and the second fan 302 is rotated by a second motor 6b. Details will be described later, but the direction of air flow by the first fan 301 (direction from the blower 300 into the inside of the clothing 50) is opposite to the direction of air flow by the second fan 302 (direction from the blower 300 to the outside of the blower 300).

[0093] The first fan cover 320 has a frame like the intake frame 43 in FIG. 4, and the first fan cover 320 is provided with a first fan cover opening 321 . The first fan cover 320 is preferably made of resin or metal such as aluminum alloy (aluminum).

[0094] The diameter D4 of the outer periphery of the first fan 301 is larger than the diameter D2 of the outer periphery of the heat sink 8 and is also larger than the diameter D5 of the outer periphery of the second fan 302. The diameter D3 of the outer periphery of the heat diffusion member 13 is larger than the diameter D2 of the outer periphery of the heat sink 8. Here, the diameter D4 of the outer periphery of the first fan 301 refers to the diameter of an imaginary circle that passes through the tip of the first fan 301 when viewed from above. Here, the diameter D5 of the outer periphery of the second fan 302 refers to the diameter of an imaginary circle that passes through the tip of the second fan 302 when viewed from above.

[0095] On the heat diffusion member 13, a cylindrical exhaust duct 310 is provided, which is a passage for discharging the air inside the blower 300 to the outside of the blower 300. The exhaust duct 310 is preferably made of a resin with low thermal conductivity. Inside the exhaust duct 310, the Peltier element unit 14 and the second fan 302 are arranged. In this case, the diameter D5 of the outer periphery of the second fan 302 is smaller than or equal to the diameter D2 of the outer periphery of the heat sink 8.

[0096] As shown in the enlarged view at the bottom of FIG. 17, an intake opening 311 is disposed below the exhaust duct 310. The blower 300 has a space (F6) between the Peltier element unit 14 and the exhaust duct 310 in the radial direction. Air below the exhaust duct 310 rises to the upper side of the exhaust duct 310 through this space (F6). From the viewpoint of ease of manufacture, the shapes of the Peltier element unit 14, the heat sink 8, and / or the exhaust duct 310 are preferably circular or rectangular.

[0097] The configuration other than that described above is basically the same as that of the blower device 250 shown in FIG.

[0098] (Air flow) First, the air flow caused by the second fan 302 will be described. As second fan 302 rotates, air on the outer periphery below exhaust duct 310 passes through intake opening 311 and enters the inside of exhaust duct 310 (F5). The air (F5) that has entered the inside of the exhaust duct 310 rises inside the exhaust duct 310 (F6) and comes into contact with the heat sink 8. The air that comes into contact with the heat sink 8 is heated by the heat sink 8 . The heated air is discharged from the inside of the exhaust duct 310 to the outside of the blower device 300 by the second fan 302 (F7). As a result, the heat sink 8 is cooled.

[0099] Next, the air flow caused by the first fan 301 will be described. As first fan 301 rotates, air on the upper periphery of exhaust duct 310 passes between intake port frames 43 and enters the periphery of exhaust duct 310 (F8). Also, air outside blower 300 passes between intake port frames 43 on side surface 28 and enters the periphery of exhaust duct 310 (F8). At this time, the air (F7) heated by the heat sink 8 and the air (F8) on the periphery of the exhaust duct 310 do not come into contact with each other because they are isolated by the exhaust duct 310. Therefore, the air (F8) on the periphery of the exhaust duct 310 is not heated.

[0100] The air (F8) around the exhaust duct 310 passes through the opening 15 of the extension frame 42 and enters the inside of the garment 50 (F9). At this time, the air (F9) that has entered the inside of the garment 50 is cooled by the extension frame 42. The air (F9) that has entered the inside of the clothing 50 and cooled passes through the first fan cover opening 321 (F10), enters between the clothing 50 and the body 51, and spreads over the entire body 51 (F12).

[0101] The air (F11) cooled by the flat surface 41 of the heat diffusion member 13 also penetrates between the clothing 50 and the body 51 and spreads over the entire body 51 (F12).

[0102] In order to further cool the air that has been cooled by passing through opening 15, first fan cover 320 is preferably made of a metal with excellent thermal conductivity, such as an aluminum alloy (aluminum). This allows first fan cover 320 to be cooled by heat diffusion member 13. Therefore, air (F10) passing through first fan cover opening 321 is further cooled, penetrates between clothing 50 and body 51, and spreads over the entire body 51 (F12). In this case, in consideration of thermal conductivity, it is preferable that the heat diffusion member 13 and the first fan cover 320 are integrated as much as possible.

[0103] (power control) The power control of the blower device 300 of embodiment 7 is almost the same as the power control of Figure 14, with the power button 71 of fan 7 serving as the power button for the first fan 301 and the power button 75 of Peltier element 9 serving as the power button for the Peltier element 9 and the second fan 302. The power supply to the Peltier element 9 and the power supply to the second fan 302 are linked. Specifically, if the power supply to the Peltier element 9 is weak, the power supply to the second fan 302 will also be weak, and if the power supply to the Peltier element 9 is strong, the power supply to the second fan 302 will also be strong. In other words, the colder the first substrate of the Peltier element 9, the stronger the wind force of the first fan 301.

[0104] Basically, the power supply to the first fan 301 is independent of the power supplies to the Peltier element 9 and the second fan 302. The power supply to the first fan 301 and the power supply to the Peltier element 9 and second fan 302 may be linked together.

[0105] According to the above embodiment, the first fan 301 draws air from outside the clothing 50 into the clothing 50 through the opening 15 of the extension frame 42. The air drawn inside is then cooled by the extension frame 42 and / or the flat surface 41 of the heat diffusion member 13, thereby cooling the entire body 51. Furthermore, the second fan 302 dissipates heat from the heat sink 8 to the outside of the clothing 50 to cool the heat sink 8, thereby improving the cooling capacity of the Peltier element unit 14.

[0106] The blower device 300 of FIG. 17 is provided with an exhaust duct 310 and has a configuration in which heat from the heat sink 8 is exhausted to the outside of the blower device 300 by a second fan 302 . If the heat dissipation effect of the heat sink 8 can be obtained only by the second fan 302, the exhaust duct 310 may not be provided. According to the above configuration, the exhaust duct 310 can be eliminated, and the simple configuration allows for size reduction and cost reduction.

[0107] (Embodiment 8) In the seventh embodiment, the second fan 302 is housed inside the exhaust duct 310 . On the other hand, in the eighth embodiment, the second fan 302 is not housed inside the exhaust duct 310, but is arranged outside (above) the exhaust duct 310.

[0108] FIG. 18 is a schematic cross-sectional view of a blower 350 according to the eighth embodiment. As shown in FIG. 18, in the blower device 350, the second fan 302 is not housed inside the exhaust duct 310, but is arranged outside (above) the exhaust duct 310. The height H1 of the exhaust duct 310 is approximately the same as the height H2 of the outer surface of the heat sink 8 in the axial direction of the blower 350. Here, the axial direction of the blower 350 is the same as the axial direction of the first motor 6a, ie, the direction rising from the bottom to the top of the paper. The height H2 of the outer surface of the heat sink 8 refers to the height H2 of the outermost surface of the heat sink 8 in the axial direction of the air blower 350 when the heat diffusion member 13 is used as the reference.

[0109] In FIG. 18, the outer diameter D5 of the second fan 302 is greater than or equal to the outer diameter D6 of the exhaust duct 310. As described above, by making the height H1 and the height H2 the same, the outer diameter D5 of the second fan 302 can be made larger than or equal to the outer diameter 6 of the exhaust duct 310. As a result, the amount of heat released from the heat sink 8 can be increased. Here, the outer diameter D6 of the exhaust duct 310 refers to the diameter of an imaginary circle that passes through the tip of the exhaust duct 310 when viewed from above.

[0110] In order to increase the air volume of exhaust duct 310, it is preferable that outer diameter D5 of second fan 302 be larger than outer diameter D6 of exhaust duct 310. However, if the outer diameter D5 of the second fan 302 is made too large, the amount of air taken into the garment 50 by the first fan 301 will decrease. Therefore, the outer diameter D5 of the second fan 302 is adjusted so as to satisfy both the amount of air discharged to the outside from the exhaust duct 310 per unit time and the amount of air taken into the garment 50 per unit time.

[0111] The air flow in the eighth embodiment is the same as that in the seventh embodiment, and therefore the description thereof will be omitted.

[0112] According to the above embodiment, the first fan 301 draws air from outside the clothing 50 into the clothing 50 through the opening 15 of the extension frame 42. The air drawn inside is then cooled by the extension frame 42 and / or the flat surface 41 of the heat diffusion member 13, thereby cooling the entire body 51. Furthermore, the second fan 302 dissipates heat from the heat sink 8 to the outside of the clothing 50 to cool the heat sink 8, thereby improving the cooling capacity of the Peltier element unit 14.

[0113] The air blower 350 of FIG. 18 is provided with an exhaust duct 310 and uses a second fan 302 to exhaust heat from the heat sink 8 to the outside of the air blower 350 . If the heat dissipation effect of the heat sink 8 can be obtained only by the second fan 302, the exhaust duct 310 may not be provided. According to the above configuration, the exhaust duct 310 can be eliminated, and the simple configuration allows for size reduction and cost reduction.

[0114] (Embodiment 9) The air blower 400 of embodiment 9 has a fifth housing 431 and a sixth housing 432 which are separate bodies, and the air blower 400 is attached to the clothing 50 by rotating the fifth housing 431 and the sixth housing 432 relative to each other, like turning a screw.

[0115] FIG. 19 is a schematic cross-sectional view of a blower 400 according to the ninth embodiment. In the fifth housing 431, a first fan cover 320, a first motor 6a, a first fan 301, a heat diffusion member 13, and a Peltier element unit 14 are arranged in this order. The fifth housing 431 also has the exhaust duct 310, the first fan cover opening 321, and a seventh flange 436.

[0116] In the sixth housing 432, the second motor 6b and the second fan 302 are arranged in this order with the upper side of the sixth housing 432 as a reference. In addition, the sixth housing 432 has a sixth flange 437 .

[0117] The exhaust duct 310 is disposed between the fifth housing 431 and the sixth housing 432 . Similar to FIG. 17, the Peltier element unit 14 and the second fan 302 are housed inside the exhaust duct 310.

[0118] The sixth housing 432 has an eighth engagement member 434 (female thread in FIG. 19) on its inner periphery, and the fifth housing 431 has a seventh engagement member 433 (male thread in FIG. 19) on its outer periphery. When the fifth housing 431 and the sixth housing 432 rotate relative to each other, the seventh engaging member 433 and the eighth engaging member 434 engage with each other.

[0119] As a result, the clothing 50 is sandwiched between the seventh flange 436 of the fifth housing 431 and the eighth flange 437 of the sixth housing 432 , and the air blower 400 is fixed to the clothing 50 . At this time, there is a gap between the heat sink 8 and the second fan 302 . The above-mentioned male and female threads may be reversed.

[0120] The air flow is the same as in the seventh embodiment, so a description thereof will be omitted.

[0121] In the ninth embodiment, if the second fan 302 can effectively exhaust heat from the heat sink 8, the exhaust duct 310 may not be provided. According to the above configuration, the exhaust duct 310 can be eliminated, and the simple configuration allows for size reduction and cost reduction.

[0122] (Embodiment 10) The tenth embodiment is an embodiment in which the first fan 301 and the second fan 302 in FIG. 17 are rotated by a single third motor 6c having a single rotation shaft 501.

[0123] FIG. 20 is a schematic cross-sectional view of a blower device 500 according to the tenth embodiment. As shown in FIG. 20, the first fan cover 320 is provided with a third motor 6c having a long rotation shaft 501. A Peltier element opening 510 that penetrates the Peltier element unit 14 is provided in the center of the Peltier element unit 14 . A heat diffusion member opening 511 penetrating the heat diffusion member 13 is also provided in the center of the heat diffusion member 13 . A bearing 502 is provided in the center of the intake port frame 43 .

[0124] A rotating shaft 501 extending from the third motor 6c passes through a heat diffusion member opening 511 and a Peltier element opening 510, and reaches a bearing 502. The tip of the rotating shaft 501 and the bearing 502 are fitted together. This allows the rotation shaft 501 to rotate without wobbling.

[0125] The rotating shaft 501 is provided with a first fan 301 and a second fan 302, and a Peltier element unit 14 is provided between the first fan 301 and the second fan 302.

[0126] The direction of the blades of second fan 302 is adjusted so that the air flow caused by second fan 302 is in a direction that goes from exhaust duct 310 to the outside of blower device 500. The direction of the blades of first fan 301 is adjusted so that the air flow caused by first fan 301 is in a direction that enters air blower device 500 from the outside into air blower device 500 .

[0127] According to the above embodiment, the first fan 301 and the second fan 302 can be rotated by one third motor 6c. The second fan 302 can discharge air from the exhaust duct 310 to the outside of the blower device 500 , and the first fan 301 can cause air to enter from the outside of the blower device 500 into the inside of the blower device 500 . Therefore, the second motor 6b in FIG. 17 can be omitted, and the size, thickness and / or cost can be reduced.

[0128] (Embodiment 11) The eleventh embodiment is a configuration in which the configuration of FIG. 20 is modified so that one double-shaft motor 6d is provided between the first fan 301 and the second fan 302.

[0129] FIG. 21 is a schematic cross-sectional view of a blower 550 according to the eleventh embodiment. As shown in FIG. 21, the blower device 550 has one double-shaft motor 6d provided between the first fan 301 and the second fan 302. The double-shaft motor 6d is provided below the heat diffusion member 13. The double-shaft motor 6d has one rotating shaft 551 extending upward and downward.

[0130] The upper shaft of the rotating shaft 551 extends upward through the heat diffusion member opening 511 and the Peltier element opening 510. The lower shaft of the rotating shaft 551 extends downward. At both ends of the rotation shaft 551, the first fan 301 (lower side) and the second fan 302 (upper side) are fixed to the rotation shaft 551. When the rotary shaft 551 rotates, the first fan 301 and the second fan 302 also rotate. The other configuration is the same as that of FIG. 20, so the description will be omitted.

[0131] According to the above embodiment, the rotary shaft 551 can be rotated stably without providing the bearing 502 .

[0132] (Embodiment 12) The twelfth embodiment has a configuration in which the second fan 302 is removed from the seventh embodiment shown in FIG. FIG. 22 is a cross-sectional view of a blower 600 according to the twelfth embodiment. As shown in FIG. 22, the blower 600 has a configuration in which the intake opening 311 of the exhaust duct 310 serves as a wall portion. The blower device 600 is an embodiment that is adopted when the outside air temperature is not so high, and therefore heat can be discharged from the heat sink 8 without any problem even without providing the second fan 302.

[0133] According to the above embodiment, the intake opening 311 at the bottom of the exhaust duct 310 is a wall (the intake opening 311 is blocked), so the air at the bottom of the exhaust duct 310 is pulled by the first fan 301 and does not escape from the exhaust duct 310 to the outside. Therefore, the air heated by the heat sink 8 can be prevented from entering the clothes 50 from the lower part of the exhaust duct 310.

[0134] (Embodiment 13) In the thirteenth embodiment, the fan 7 of FIG. 9 of the second embodiment is improved so that a single fan 701 exhausts the air heated by the heat sink 8 from the blower 700 to the outside (P1), and air outside the outer periphery of the heat sink 8 in the radial direction enters the inside of the garment 50 (P2).

[0135] FIG. 23 is a schematic cross-sectional view of a blower 700 according to the eleventh embodiment. The bottom diagram of FIG. 23 is an enlarged view of the fan 701. As shown in FIG. 23, the blower device 700 includes one second motor 6b and one fan 701 attached to the second motor 6b. The fan 701 has a first blade 710 and a second blade 720, which are symmetrical with respect to the rotation axis of the second motor 6b. The second motor 6b rotates clockwise, and the fan 701 also rotates clockwise.

[0136] As shown in the enlarged view of FIG. 23, one of the first blades 710 has a first blade 711 on the inside in the radial direction and a second blade 712 on the outside in the radial direction. The other second blade 720 has a third blade 721 on the radially inner side and a fourth blade 722 on the radially outer side.

[0137] When the fan 701 rotates clockwise, the orientation of the blades of the first blade 711 and the third blade 721 is adjusted so that the air heated by the heat sink 8 is discharged from the blower device 700 to the outside (P1). In other words, the first wing 711 and the third wing 721 are twisted so that the lower sides of the first wing 711 and the lower sides of the third wing 721 are under negative pressure.

[0138] When the fan 701 rotates clockwise, the orientation of the blades of the second blade 712 and the fourth blade 722 is adjusted so that air outside the outer periphery of the heat sink 8 in the radial direction enters the inside of the clothing 50 (P2). In other words, the second wing 712 and the fourth wing 722 are twisted so that the upper sides of the second wing 712 and the fourth wing 722 are under negative pressure. With the above-described configuration, it is possible to generate winds in different directions inside and outside the fan 701 with a single blade.

[0139] According to the above-described embodiment, one fan 701 and one second motor 6b can exhaust air heated by the heat sink 8 from the blower device 700 to the outside (P1), and air outside the outer periphery of the heat sink 8 in the radial direction can be introduced into the garment 50 (P2). Therefore, it is possible to dissipate heat from the heat sink 8, and a small, thin fan device 700 can be realized. The fan 701 may have more than two blades, ie, the first blade 710 and the second blade 720.

[0140] In addition, the blower devices 300, 350, 500, 550 using the mounting ring 4 and two fans, the first fan 301 and the second fan 302, as shown in Figures 17-18 and 20-23 may also be in the form of a blower device 400 using two housings (431, 432) as shown in Figure 19.

[0141] In FIG. 14, power is supplied to the above-mentioned blower device from a mobile battery 65, but power may also be supplied to the above-mentioned blower device by adjusting the voltage from a commercial power outlet such as 100V or 200V.

[0142] The present invention may also be applied to a handheld electric fan.

[0143] In the above embodiment, the first substrate 10 cools and serves as a cooling portion, and the second substrate 12 generates heat and serves as a heat generating portion. By reversing the direction of the current through the Peltier element 9, the heat generating portion and the cooling portion can be reversed. In this way, the inside of the clothes 50, 90 can be warmed, and the entire body 51 can be warmed.

[0144] The inventions according to the above-described embodiments (embodiments 1 to 13) can be replaced or combined as long as no contradiction occurs.
