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. 22 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] One embodiment of the clothing disclosed herein is an air blower device attached to the clothing, comprising a Peltier element having a first substrate which is a cooling unit and a second substrate which is a heating unit, a heat exchange plate provided on the second substrate, and a fan, wherein the Peltier element and the heat exchange plate have openings, the first substrate is positioned inside the clothing, air outside the clothing is drawn into the inside of the clothing through the opening by the fan, the air drawn into the inside of the clothing is cooled by the first substrate, the heat exchange plate is positioned outside the clothing, and the air heated by the heat exchange plate is diffused outside the clothing by the fan. [Effects of the Invention]

[0013] The air blower according to one aspect of the present disclosure allows air (outside air) outside the clothing to be drawn into the clothing through the opening, and the Peltier element cools the drawn-in air, 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.

DETAILED DESCRIPTION OF THE INVENTION

[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] FIG. 1 is a schematic diagram of a blower 1 attached to clothing 50 in embodiment 1, FIG. 2 is a schematic oblique view of the blower 1 in embodiment 1, and FIG. 3 is a schematic exploded oblique view 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 (outer side), and the side that is closer to the person is defined as the lower side (inner side). Therefore, the outer side of clothing 50 is the upper side, and the inner side of clothing 50 is the lower side.

[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 to secure the two air blowers 1 to the garment 50. The air blowers 1 are inserted into the two holes to secure the air blowers 1 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 FIGS. 2 and 3, 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. 12). Next, each component will be described in detail.

[0023] (Main body) Figure 4 is a schematic plan view of the main body 3 of the blower 1 in embodiment 1, Figure 5 is a schematic front view of the main body 3 of the blower 1 in embodiment 1, and Figure 6 is a schematic bottom view of the main body 3 of the blower 1 in embodiment 1. 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.

[0024] An intake port 42 is provided on the top surface 27, an exhaust port 43 is provided on the side surface 28, and a first engagement member 17 is provided below the exhaust port 43. In the case of Figure 5, the first engagement member 17 is a male screw. The intake port 42 and the exhaust port 43 are vents formed by a frame 44 . A first flange 20 is provided on the bottom surface 29 .

[0025] The main body 3 has a Peltier element unit 14 (heat exchange plate 8 and Peltier element 9) which will be described later.

[0026] As shown in FIG. 6, the bottom surface 29 has an opening 15 . The bottom surface 29 has an expanded metal plate 13 around the opening 15, which will be described later. The expanded metal plate 13 also has an opening 15 .

[0027] (Mounting ring) Figure 7 is a schematic oblique view of the mounting ring 4 of the blower 1 in embodiment 1, Figure 8 is a schematic plan view of the mounting ring 4 of the blower 1 in embodiment 1, and Figure 9 is a schematic front view of the mounting ring 4 of the blower 1 in embodiment 1. 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. As shown in FIGS. 7-9, the mounting ring 4 has a mounting ring body 22 and a second flange 21 on the underside of the mounting ring body 22. A second engagement member 18 is provided on the inside of the mounting ring body 22. In the case of Figures 7-9, the second engagement member 18 is an internal thread.

[0028] 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.

[0029] (Peltier element unit) Figure 10A is a schematic oblique view of the Peltier element unit 14 in embodiment 1 as seen from above, Figure 10B is a schematic oblique view of the Peltier element unit 14 in embodiment 1 as seen from below, Figure 11A is a schematic plan view of the Peltier element unit 14 in embodiment 1, Figure 11B is a schematic front view of the Peltier element unit 14 in embodiment 1, and Figure 11C is a schematic bottom view of the Peltier element unit 14 in embodiment 1. As shown in FIGS. 10-11C, the Peltier element unit 14 has a heat exchange plate (heat sink) 8 and a Peltier element 9 below the heat exchange plate 8. The Peltier element unit 14 is circular, and the heat exchange plate 8 and the Peltier element 9 are also circular. The heat exchange plate 8 is preferably made of a metal such as an aluminum alloy (aluminum) having good thermal conductivity. The area of ​​the heat exchange plate 8 is larger than the area of ​​the Peltier element 9. The Peltier element unit 14 has an opening 15 at the center that passes through the heat exchange plate 8 and the Peltier element 9 . As will be described later, air outside the garment 50 passes through the openings 15 and enters the inside of the garment 50 .

[0030] As shown in FIGS. 10A and 10B, 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 23 is connected to one side of the semiconductor 11, and a second lead portion 24 is connected to the other side of the semiconductor 11. In the case of FIGS. 10A and 10B, when a positive voltage is applied to first lead portion 23 and a negative voltage is applied to second lead portion 24, first substrate 10 is cooled and second substrate 12 is heated. The heat of the heated second substrate 12 is transferred to the heat exchange plate 8 , and the transferred heat is dissipated by the heat exchange plate 8 .

[0031] FIG. 12 is a schematic perspective view showing a state in which the air blower 1 is attached to clothing 50 in the first embodiment, and FIG. 13 is a schematic cross-sectional view of the air blower 1 in the first embodiment. As shown in FIG. 12, 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 .

[0032] 13 , 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.

[0033] 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.

[0034] The main body 3 has, in order from the top, a top surface 27, a side surface 28, and a bottom surface 29. The body 3 has a thick bottom 26 with a bottom surface 29 . Most of the main body 3 , excluding the bottom surface 29 , protrudes outside the clothing 50 .

[0035] The motor 6 is provided on the upper surface 27, and the fan 7 connected to the motor 6 is provided below the motor 6. A Peltier element unit 14 is provided below the fan 7 with a gap between it and the fan 7 . The Peltier element unit 14 is fixed to the bottom portion 26 by fitting the Peltier element 9 into a main body opening 45 provided in the bottom portion 26.

[0036] (expanded metal plate) As shown in FIG. 13, an expanded metal plate 13 having an area larger than that of the first substrate 10 is provided below the first substrate 10 , and the expanded metal plate 13 protrudes below the bottom surface 29 . The expanded metal plate 13 is preferably made of a metal such as an aluminum alloy (aluminum) that has good thermal conductivity.

[0037] The heat (cold temperature) of the first substrate 10 is transferred to the extended metal plate 13, and the heat (cold temperature) spreads over the entire surface of the extended metal plate 13, which has a large area, and the entire surface of the extended metal plate 13 is cooled. As a result, the expanded metal plate 13 having a large area can cool the air between the clothing 50 and the body 51, and cool the entire body 51.

[0038] The heat exchange plate 8 is arranged on the bottom 26 and is located close to the fan 7 . The heat exchange plate 8 is disposed outside the clothes 50 .

[0039] (wind flow) Explain the wind flow. There are two wind currents. (1) One type of wind flow is the flow of air taken in through the air intake 42 and expelled from the air exhaust 43. (2) The second wind flow is the flow of air taken in through the air intake 42, passing through the opening 15 and entering the inside of the garment 50.

[0040] FIG. 14 is a schematic diagram showing the flow of air in the heat exchange plate 8 in the first embodiment, and FIG. 15 is a schematic diagram showing the flow of air in the expanded metal plate 13 in the first embodiment. 14 is a view of the heat exchange plate 8 observed from above, and FIG. 15 is a view of the heat exchange plate 8 observed from below.

[0041] (1) Explain the wind flow in one eye.

[0042] 14, the heat exchange plate 8 has a plate-shaped main body plate 47 and multiple fins 48. The multiple fins 48 are rectangular (in FIG. 14, a rectangle with the longer sides extending outward) and protrude outward from the main body plate 47. A plurality of fins 48 are arranged on the body plate 47 with row grooves 55 and column grooves 56 .

[0043] As shown in FIG. 13, when the fan 7 is rotated by the motor 6, air outside the blower 1 passes through the air intake 42 and enters the inside of the blower 1 (F1). The air that has entered then hits the heat exchange plate 8, and the heat exchange plate 8 is cooled by the air that hits the heat exchange plate 8.

[0044] As shown in Figure 14, the air heated by hitting the heat exchange plate 8 passes through the row grooves 55, moves to the right and left sides of the paper, and is discharged from the exhaust port 43 provided on the side surface 28 (F2). The air that has been heated by hitting the heat exchange plate 8 passes through the grooves 56 in the row, moves to the upper and lower sides of the paper surface, and is discharged from the exhaust port 43 (F2). As shown in FIG. 13, the surface of the main plate 47 and the fins 48 are positioned outside the clothing 50 . By making the distance H1 between the surface of the main body plate 47 and the surface of the clothing 50 equal to or greater than zero, the air heated by the fins 48 can be discharged from the exhaust port 43 on the outside of the clothing 50 without penetrating inside the clothing 50. The vertical length of the exhaust port 43 is longer than the length of the fins 48 so that the air heated by the fins 48 can be discharged.

[0045] On the side surface 28 of the main body 3, a first engagement member 17 (male thread) is arranged below the exhaust port 43 so as not to prevent the discharge of air heated by the fins 48. The male thread is formed up to the first flange 20.

[0046] In the mounting ring body 22 of the mounting ring 4, the outer surface of the mounting ring body 22 is positioned below the exhaust port 43 so as not to prevent the exhaust of the air heated by the fins 48. A second engagement member 18 (female thread) is disposed on the entire inner surface of the attachment ring 4. The female thread is formed up to the second flange 21.

[0047] According to the above embodiment, the air that has been heated by hitting the heat exchange plate 8 outside the clothing 50 is discharged from the exhaust port 43 outside the clothing 50 and diffused.

[0048] (2) Explain the wind flow in the two eyes. As shown in FIG. 13, when the fan 7 is rotated by the motor 6, air outside the blower 1 passes through the air intake 42 and enters the inside of the blower 1 (F1). Then, part of the infiltrated air passes through the opening 15 and enters the inside of the garment 50 (F3). Part of the air that has entered the clothing 50 hits the body 51, and part of it becomes wind in a direction parallel to the body 51 (horizontal direction) (F4). This horizontal wind (F4) spreads radially from the opening 15 as shown in FIG. The air that has entered the clothing 50 creates a space between the blower 1 and the body 51, causing the clothing 50 to expand.

[0049] As shown in FIG. 13, the expanded metal plate 13 cools the air that has entered the garment 50 . The air cooled by the expanded metal plate 13 spreads into the space between the blower 1 and the body 51, and can cool the entire body 51.

[0050] According to the above embodiment, the fan 7 draws air from outside the clothing 50 into the clothing 50 through the opening 15, and the air drawn into the clothing 50 is cooled by the expanded metal plate 13 or the first substrate 10. In addition, the heat exchange plate 8 is disposed outside the clothing 50, and the air heated by the heat exchange plate 8 is diffused outside the clothing 50 by the fan 7. As a result, the blower 1 sends cooled wind (air) into the space between the body 51 and the clothes 50, so that the entire body 51 can be cooled. 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.

[0051] 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.

[0052] In the above-described embodiment, the expanded metal plate 13 cools the air that penetrates from the outside of the clothing 50 to the inside of the clothing 50, but if the expanded metal plate 13 is not provided on the first substrate 10, the first substrate 10 cools the air that penetrates to the inside of the clothing 50.

[0053] (Embodiment 2) In the blower 1 of the first embodiment, the mounting ring 4 is attached to the outside of the main body 3 having the motor 6, the fan 7, the heat exchange plate 8, and the Peltier element unit 14. In the air blower 30 of embodiment 2, the first housing 31 and the second housing 32 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.

[0054] FIG. 16 is a schematic cross-sectional view of the blower device 30 according to the second embodiment. The first housing 31 of the second embodiment includes the motor 6, the fan 7, and a third flange . The second housing 32 of the second embodiment has a heat exchange plate 8 , a Peltier element unit 14 , and a fourth flange 37 .

[0055] The first housing 31 has a third engagement member 33 (female thread in FIG. 16) on the inside, and the second housing 32 has a fourth engagement member 34 (male thread in FIG. 16) on the outside. 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 are fitted together.

[0056] 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.

[0057] As shown in Figures 14 and 16, the air heated by hitting the heat exchange plate 8 passes through the row grooves 55, moves to the right and left sides of the paper, and is discharged from the exhaust ports 43 provided on the side surface 28. The air that has been heated by hitting the heat exchange plate 8 passes through the grooves 56 in the row, moves to the upper and lower sides of the paper surface, and is discharged from the exhaust port 43.

[0058] An exhaust port 43 is provided on the lower side of the first housing 31 .

[0059] A third engaging member 33 (female thread) is arranged inside the first housing 31 below the exhaust port 43 so as not to prevent the discharge of air heated by the fins 48. The female thread is formed to the inside of the third flange 36.

[0060] In the second housing 32, the upper surface of the second housing 32 is positioned below the exhaust port 43 so as not to prevent the air heated by the fins 48 from being discharged. A fourth engagement member 34 (male thread) is disposed on the outer circumferential surface of the second housing 32. The male thread 34 is formed up to a fourth flange 37.

[0061] The Peltier element unit 14 is fixed by fitting the Peltier element 9 into a second housing opening 46 provided in the second housing 32. An expanded metal plate 13 having an area larger than that of the second substrate 12 is provided below the second substrate 12, and the expanded metal plate 13 protrudes downward from the second housing opening 46.

[0062] As in embodiment 1, by making the distance H2 between the surface of the main body plate 47 and the surface of the clothing 50 greater than or equal to zero, the air heated by the fins 48 can be discharged from the exhaust port 43 on the outside of the clothing 50 without entering the inside of the clothing 50. The two airflows are the same as those in the first embodiment, and therefore will not be described here.

[0063] According to the above aspect, in the air blower 30, the air that has been heated by hitting the heat exchange plate 8 outside the clothes 50 is discharged from the exhaust port 43 outside the clothes 50 and diffused.

[0064] The air blower 30 draws air (outside air) from outside the clothing 50 into the inside of the clothing 50 through the opening 15, and cools the air drawn in by the first substrate 10 or the expanded metal plate 13, thereby cooling the entire body 51. The blower 30 can be easily attached to clothing by inserting it 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.

[0065] (Variation 1) In the first modification, a plurality of openings 15 are provided in the Peltier element unit 14 and the extended metal plate 13. FIG. 17 is a schematic plan view of the plurality of openings 15 in the first modification, and FIG. 18 is a schematic bottom view of the plurality of openings 15 in the first modification. The center of the Peltier element unit 14 is located directly below the motor 6, and the wind generated by the fan 7 is relatively weak. Therefore, as shown in FIG. 17, a plurality of openings 15 (four in FIG. 17) are provided on the outside of the Peltier element unit 14 except for the central portion. As shown in FIG. 18, the expanded metal plate 13 is also provided with a plurality of openings 15 (four in FIG. 18) on the outer side of the expanded metal plate 13 except for the central portion.
