Description

Technical Field

[0001] The present disclosure relates to a blower device having a cooling member and a fan.

Background Art

[0002] Patent Document 1, which is the prior art, discloses an air conditioning unit 500 that locally cools the body 510 using a Peltier element 117. FIG. 13 is a cross-sectional view of the air conditioning unit 500 of Patent Document 1. Patent Document 1 will be described using FIG. 13. The air conditioning unit 500 is to be worn on the clothing 150. The air conditioning unit 500 has a heat insulating pad 530 disposed inside the clothing 150 and a fixing pad 140 disposed outside the clothing 150.

[0003] Three protrusions provided on the fixing pad 140 pass through three small-diameter holes provided in the clothing 150 and are inserted into three recesses provided in the heat insulating pad 530, and the air conditioning unit 500 is worn on the clothing 150.

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

[0005] The Peltier element 117 is provided below the fixing pad 140, in a direction perpendicular to the clothing 150 (hereinafter referred to as the vertical direction), and is disposed at the same position as the clothing 150. An auxiliary metal plate 119 is provided below the cooling part of the Peltier element 117, and an expanded metal plate 520 is further provided below the auxiliary metal plate 119. The heat (cold temperature) of the cooling part of the Peltier element 117 is transmitted to the expanded metal plate 520 through the auxiliary metal plate 119, and the expanded metal plate 520 is cooled. As the expanded metal plate 520 comes into close proximity to or contact with the body 510, a localized area of ​​the body 510 (approximately the same area as the expanded metal plate 520) is cooled.

[0006] The heatsink 115 is located on the outside of the garment 150. The heatsink 115 is cooled by the airflow (F1) from the fan 114. At this time, the airflow (F1) from the fan 114 is heated by the heatsink 115. The air heated by the heatsink 115 is bent from the vertical direction (F1) to the horizontal direction (F2) by the heatsink 115. Then, outside the garment 150, the air heated by the heatsink 115 is discharged (F2) from the exhaust port 113 to the outside of the fan cover 111.

[0007] With this configuration, in Patent Document 1, the air heated by the heat sink 115 is diffused on the outside of the garment 150 and does not penetrate into the inside of the garment 150. Therefore, Patent Document 1 can efficiently cool the expanded metal plate 520 inside the garment 150 and cool a localized area of ​​the body (approximately the same area as the expanded metal plate 520). [Prior art documents] [Patent Documents]

[0008] [Patent Document 1] Japanese Patent Publication No. 2021-113371 [Overview of the Initiative] [Problems that the invention aims to solve]

[0009] However, Patent Document 1 cools a localized area of ​​the body (approximately the same area as the expanded metal plate 520) and does not cool the air inside the clothing 150 (the air between the clothing 150 and the body 510), so there is room for improvement. Furthermore, in Patent Document 1, the fan 114, the Peltier element 117, and the heat sink 115 overlap in the vertical direction, which increases the thickness of the air conditioning unit 500, making it difficult to make it thinner, and thus there is room for improvement.

[0010] A blower according to one aspect of this disclosure solves the above-mentioned problems. [Means for solving the problem]

[0011] A blower according to one aspect of the present disclosure comprises a first housing, a second housing, a Peltier element, a motor, a first fan, and a second fan, and is a blower that is attached to clothing. The Peltier element comprises a first substrate which is a cooling section, a second substrate which is a heating section, and a semiconductor disposed between the first substrate and the second substrate. The motor is positioned at a distance from the Peltier element and rotates the first fan and the second fan. The first housing includes the first fan, the first intake port, the first exhaust port, and the first heat sink that contacts the first substrate. The first fan is positioned at a distance from the Peltier element, and as the first fan rotates, it draws in air from the first intake port, brings the drawn-in air into contact with the first heat sink, and discharges the air that has come into contact with the first heat sink into the inside of the garment from the first exhaust port. The second housing includes the second fan, a second intake port, a second exhaust port, and a second heatsink that contacts the second substrate. The second fan is positioned at a distance from the Peltier element, and as the second fan rotates, it draws in air from the second intake port, brings the drawn-in air into contact with the second heat sink, and discharges the air that has come into contact with the second heat sink to the outside of the garment through the second exhaust port.

[0012] A blower according to another aspect of the present disclosure is a blower that is attached to clothing, comprising a first housing, a second housing, a cooling member, a motor, a first fan, and a second fan. The motor is positioned at a distance from the cooling member and rotates the first fan and the second fan. The first housing has the first fan, a first air inlet, and a first air outlet. The first fan is disposed at a distance from the cooling member. When the first fan rotates, air is drawn in from the first air inlet, the drawn-in air is brought into contact with the cooling member, and the air that has been brought into contact with the cooling member is discharged from the first air outlet into the interior of the clothing. The second housing has the second fan and a second air inlet. The second fan is disposed at a distance from the cooling member. When the second fan rotates, air is drawn in from the second air inlet, the drawn-in air is brought into contact with the cooling member, and the air that has been brought into contact with the cooling member is discharged from the first air outlet into the interior of the clothing.

[0015] The following describes specific embodiments of this disclosure. However, some unnecessarily detailed descriptions may be omitted. For example, detailed descriptions of already well-known matters or redundant descriptions of substantially identical configurations may be omitted. This is to avoid the following description becoming unnecessarily verbose and to facilitate understanding by those skilled in the art. The inventors provide the accompanying drawings and the following description so that those skilled in the art can fully understand this disclosure, and not to limit the subject matter described in the claims. In the following description, identical or similar components are denoted by the same reference numerals.

[0016] (Embodiment 1) First, I will explain the overall general configuration of the blower 1, and then I will describe the details of each component.

[0017] (Regarding the overall configuration of the blower system) The following outline of the blower 1 in Embodiment 1 of this disclosure will be described with reference to the drawings.

[0018] Figure 1 is a schematic front view of the blower 1 attached to the back fabric 3 of the garment 200 in Embodiment 1, Figure 2 is a schematic perspective view of the blower 1 in Embodiment 1, Figure 3 is a schematic diagram showing the airflow through the second housing 40 of the blower 1 in Embodiment 1, Figure 4 is a schematic diagram showing the airflow through the first housing 30 of the blower 1 in Embodiment 1, and Figure 5 is a schematic exploded perspective view of the blower 1 in Embodiment 1.

[0019] As shown in Figure 1, the garment 200 has an outer fabric 2 and an inner fabric 3. The air blower 1 is located near the back of the back fabric 3. As shown in Figures 2 and 5, the blower 1 has a first housing 30 and a second housing 40, and the blower 1 is fixed in place by sandwiching the clothing 200 between the first housing 30 and the second housing 40. In other words, the first housing 30 is located inside the garment 200, and the second housing 40 is located outside the garment 200 (Figure 6). The garment 200 is made of thick fabric and reinforces the fixing of the blower 1 with a reinforcing member 60 having an opening.

[0020] Here, using the case where the clothing 200 is worn on a person's body 51 (Figure 6) as a reference, in the blower device 1, the side that moves away from the body 51 is defined as the outside, and the side that moves closer to the body 51 is defined as the inside. Furthermore, the head side of a person is defined as the upper side, and the feet side is defined as the lower side.

[0021] As shown in Figure 5, the blower 1 has a first fan 34, a second fan 44, and a cooling member 14, and cools the entire body 51. The shape of the blower 1 is elongated vertically. The cooling member 14 has a cooling section in which at least a part or all of the cooling member 14 is a cooling section, and the body is cooled by the cooling section. In Embodiment 1, the cooling member 14 is a Peltier element unit 14. The Peltier element unit 14 includes a Peltier element 9, a first heat sink 33, and a second heat sink 43.

[0022] The first housing 30 has a first intake port 31 and a first exhaust port 32. The second housing 40 has a second intake port 41 and a second exhaust port 42.

[0023] The first fan 34 and the Peltier element unit 14 are located at different distances, and the second fan 44 and the Peltier element unit 14 are also located at different distances. The first air intake port 31 and the first fan 34 are positioned opposite each other, and the second air intake port 41 and the second fan 44 are positioned opposite each other.

[0024] As will be described in more detail later, the dual-shaft motor 6 has a rotating shaft 7, and a first fan 34 and a second fan 44 are arranged on both sides of the rotating shaft 7. In other words, the dual-shaft motor 6 is located between the first fan 34 and the second fan 44.

[0025] (Wind currents) Next, I will briefly explain airflow. As shown in Figure 3, the rotation of the second fan 44 draws in air F1 from the second intake port 41 and discharges the drawn-in air F2 from the second exhaust port 42. At that time, the inhaled air F1 passes between the second heat sinks 43 and is heated by the second heat sinks 43 (Figure 6). Therefore, the air F2 is heated and becomes hot air.

[0026] As shown in Figure 4, the rotation of the first fan 34 draws in air F3 from the first intake port 31, and the drawn-in air is discharged from the first exhaust port 32 (F4). At that time, the inhaled air F3 passes between the cooling section of the Peltier element unit 14 and the first heat sink 33, which is in contact with it, and is cooled (Figure 6). Therefore, the air F4 is cooled by the cooling section and becomes cold air. This allows the body 51 to be cooled. Furthermore, a portion of the air F4 (F5) is drawn in again through the first air intake port 31 and further cooled.

[0027] According to the above embodiment, the entire body 51 can be cooled by the air F4 cooled in the cooling section of the Peltier element unit 14.

[0028] Furthermore, the blower 1 may be installed at any position on the front fabric 2 or the back fabric 3.

[0029] Next, we will explain the details of each component.

[0030] (First Housing and Second Housing) Figure 6 is a schematic cross-sectional view of the blower device 1 in Embodiment 1. As shown in Figure 6, the blower 1 is formed by combining the first housing 30 and the second housing 40 into a single unit. A base 20 extending in the vertical direction is provided at the center of the blower 1 in the left-right direction. The base 20 holds the motor 6 (in this case, a dual-axis motor) and the Peltier element unit 14, and separates the first housing 30 and the second housing 40. The base 20 is plate-shaped and preferably made of resin, metal, or the like.

[0031] The first housing 30 houses the first fan 34 and the first heatsink 33. The first housing 30 has a first intake port 31 located opposite the first fan 34 and a first exhaust port 32 located opposite the first heatsink 33.

[0032] In Figure 6, the base 20 is provided in the first housing 30. The base 20 may also be provided in the second housing 40.

[0033] A first flange 17 is provided on the entire or partial outer circumference of the first housing 30, and a second flange 18 is provided on the entire or partial outer circumference of the second housing 40. The blower 1 is fixed to the backing fabric 3 by being sandwiched between the first flange 17 and the second flange 18. Furthermore, a reinforcing member 60 may be sandwiched between the first flange 17 and the second flange 18.

[0034] (First fan and second fan) A first fan 34 and a second fan 44 are positioned at the top of the blower 1. A motor 6 (double-shaft motor) is positioned between the first fan 34 and the second fan 44. The dual-shaft motor 6 is fixed to the base 20 and has rotating shafts 7 that protrude in the left and right directions. A first fan 34 and a second fan 44 are provided at both ends of the rotating shaft 7.

[0035] The first fan, number 34, has the first boss, number 15, and the first feather, number 39. The first boss (item 15) and the first wing (item 39) are glued together and are a single unit.

[0036] The second fan 44 has the second boss 16 and the second feather 49. The second boss 16 and the second wing 49 are glued together and are a single unit.

[0037] The first boss 15 is fitted to the rotating shaft 7, and the second boss 16 is fitted to the rotating shaft 7. As the rotating shaft 7 rotates, the first fan 34 and the second fan 44 also rotate. The first fan 34 and the second fan 44 are preferably, for example, sirocco fans.

[0038] As the first fan 34 rotates, it draws in air F3 from the first intake port 31, changes the direction of the air F3 by 90 degrees, and discharges the downward-facing air F3a. As the second fan 44 rotates, it draws in air F1 from the second intake port 41, changes the direction of the air F1 by 90 degrees, and discharges the downward-facing air F1a.

[0039] (Peltier element unit) Figure 7A is a schematic perspective view of the Peltier element unit 14 in Embodiment 1, and Figure 7B is a schematic cross-sectional view of the Peltier element unit 14 in Embodiment 1. As shown in Figures 7A and 7B, the Peltier element unit 14 includes a first heat sink 33, a Peltier element 9, and a second heat sink 43. The Peltier element 9 is located between the first heat sink 33 and the second heat sink 43.

[0040] As shown in Figure 7B, the Peltier element 9 has a first substrate 10 which is a cooling section, a second substrate 12 which is a heating section, and a semiconductor 11, with the semiconductor 11 being provided between the first substrate 10 and the second substrate 12.

[0041] The first heatsink 33 is in contact with the first substrate 10, and the first heatsink 33 is cooled by the first substrate 10. The second heatsink 43 is in contact with the second substrate 12, and the second heatsink is heated by the second substrate 12. The first heat sink 33 and the second heat sink 43 are preferably made of a metal with good thermal conductivity, such as an aluminum alloy (aluminum).

[0042] As shown in Figure 7A, the first heat sink 33 and the second heat sink 43 have holes in their four corners. The clamping member 21 is, for example, a bolt and a nut. The bolt and nut pass through the hole, and the bolt and nut tighten the first heat sink 33 and the second heat sink 43, thereby sandwiching the Peltier element 9 between the first heat sink 33 and the second heat sink 43. Furthermore, the first heat sink 33 and the second heat sink 43 are fastened together with bolts and nuts, and the base body 20 is sandwiched between the first heat sink 33 and the second heat sink 43, thereby fixing the Peltier element unit 14 to the base body 20.

[0043] Furthermore, the clamping member 21 may have a bolt on one end and a screw hole on the other end that engages with a bolt provided on the first heat sink 33 or the second heat sink 43.

[0044] (Wind currents) (1) Regarding the first housing The airflow in the first housing 30 will now be explained. As shown in Figure 6, when the rotating shaft 7 of the dual-shaft motor 6 rotates, the first fan 34 (sirocco fan) rotates. As the first fan 34 rotates, air F3 is drawn into the first housing 30 from the first intake port 31. The direction of the air F3 is perpendicular to the surface of the base 20 (moving from right to left on the page). The first fan 34 changes the direction of the air F3 by 90 degrees and discharges the air F3a downwards (parallel to the base 20).

[0045] Figure 8 is a schematic diagram showing the airflow in the first heat sink 33 and the second heat sink 43 of Embodiment 1. As shown in Figure 8, the expelled air F3a passes between the fins of the first heat sink 33. Air F3b moves from the upper right to the lower left of the paper, passing between the fins of the first heatsink 33. As the air F3b passes between the fins of the first heatsink 33, the air F3b is cooled by the first heatsink 33.

[0046] As shown in Figure 6, the cooled air F3b hits the bottom surface of the first housing 30, then rises along the right side of the first housing 30, and is discharged to the outside of the first housing 30 through the first outlet 32 ​​(air F4). In other words, the air F4 is discharged into the space between the back fabric 3 and the body 51. This allows the entire body 51 to be cooled. Furthermore, a portion of the air F4 (air F5) is drawn back into the first air intake 31 and further cooled by the first heat sink 33, becoming colder. Then, a portion of the further cooled air F4 cools the body 51, and another portion of the air F4, air F5, is drawn back into the first air intake 31 and circulated. As a result, the entire body 51 is gradually cooled.

[0047] (2) Regarding the second housing I will now explain the airflow in the second housing 40. When the rotating shaft 7 of the dual-shaft motor 6 rotates, the second fan 44 (sirocco fan) rotates. As the second fan 44 rotates, air F1 is drawn into the second housing 40 from the second air intake 41. The direction of the air F1 is perpendicular to the surface of the base 20 (moving from left to right on the page). The second fan 44 changes the direction of the air F1 by 90 degrees and discharges the air F1a downwards (parallel to the base 20).

[0048] As shown in Figure 8, the expelled air F1a passes between the fins of the second heat sink 43. Air F1b moves from the upper right to the lower left of the paper, passing between the fins of the second heatsink 43. As the air F1b passes between the fins of the second heatsink 43, the air F1b is heated by the second heatsink 43.

[0049] As shown in Figure 6, the heated air F1b strikes the bottom surface of the second housing 40, then rises along the left side of the second housing 40, and is discharged to the outside of the second housing 40 through the second outlet 42 (air F2). In other words, air F2 is discharged to the outside of the back fabric 3.

[0050] According to the above embodiment, the entire body 51 can be cooled. Furthermore, the tilt of the first blade 39 of the first fan 34 and the tilt of the second blade 49 of the second fan 44 are in opposite directions.

[0051] (power supply) A mobile battery (not shown) is installed at any position on the blower 1. The mobile battery and motor 6 and the mobile battery and Peltier element 9 are electrically connected, and power is supplied from the mobile battery to motor 6 and from the mobile battery to Peltier element 9.

[0052] Basically, the power supply to the first fan 34 and the second fan 44 is independent of the power supply to the Peltier element 9. Furthermore, the power supply to the first fan 34 and the second fan 44 may be linked to the power supply to the Peltier element 9.

[0053] (Embodiment 2) In the second embodiment, the blower 100 is configured such that the motor 6 is not a dual-shaft motor, but rather the motor 6 is located in either the first housing 30 or the second housing 40. Figure 9 is a schematic cross-sectional view of the blower 100 in Embodiment 2. As shown in Figure 9, a motor 6 is provided at the first air intake port 31 of the first housing 30.

[0054] The motor 6 has a rotating shaft 7, and a first fan 34 and a second fan 44 are fixed to the rotating shaft 7. A bearing 23 is provided at the second air intake port 41 of the second housing 40, and the rotating shaft 7 and the bearing 23 are fitted together. This prevents the rotating shaft 7 from vibrating when it rotates. Furthermore, the base body 20 has a base body opening through which the rotating shaft 7 passes.

[0055] According to the above embodiment, a standard single-sided motor 6 can be used.

[0056] (Embodiment 3) Embodiment 3 is a configuration in which a water-retaining member 25 is provided in the first housing 30. Figure 10 is a schematic cross-sectional view of the blower 110 in Embodiment 3. As shown in Figure 10, a water-retaining member 25 and a water-retaining member holder 26 for holding the water-retaining member 25 are provided so as to cover the first outlet 32 ​​of the first housing 30. The water-retaining member holder 26 has a water-retaining member holder opening 27.

[0057] The water-holding member holder 26 has an opening at its top, allowing the user to insert the water-holding member 25 through the opening and hold the water-holding member 25 in the water-holding member holder 26.

[0058] The water-holding member 25 holds water and vaporizes the held water using the air F3c from the first fan 34. The vaporized water vapor passes through the water-holding member holder opening 27 and comes into contact with the body 51, thereby cooling the body 51.

[0059] Furthermore, the water-retaining member 25 can discharge mist larger than the size of water vapor from the water-retaining member holder opening 27 to the inside of the back fabric 3. The mist then passes through the water-retaining member holder opening 27 and hits the body 51, thereby cooling the body 51. Furthermore, the water-retaining member 25 is preferably made of a nonwoven fabric, woven fabric, or similar material that allows water to spread evenly due to surface tension.

[0060] (Embodiment 4) Embodiment 4 is a configuration in which a first cooling member 35 and a second cooling member 45 are used instead of the Peltier element 9. Figure 11 is a schematic cross-sectional view of the blower 120 in Embodiment 4. As shown in Figure 11, the first housing 30 has a first holder 36, and the first holder 36 has a first holder opening 37. The first cooling member 35 is held in the first holder 36.

[0061] The second housing 40 has a second holder 46, and the second holder 46 has a second holder opening 47. The second cooling member 45 is held in the second holder 46.

[0062] The first cooling member 35 and the second cooling member 45 are, for example, a coolant at a temperature lower than room temperature, or cold water in a bag. The first cooling member 35 and / or the second cooling member 45 are referred to as cooling members.

[0063] The motor (double-shaft motor) 6 is positioned at a distance from the first cooling member 35 and rotates the first fan 34 and the second fan 44.

[0064] The first fan 34 is positioned at a distance from the first cooling member 35, and as the first fan 34 rotates, air is drawn in from the first air intake port 31 (F3). The first fan 34 changes the direction of the intake air F3 by 90 degrees and discharges the downward-facing F3a. When the discharged air F3a and the first cooling member 35 are brought into contact at the top of the first holder 36, the air F3a is cooled by the first cooling member 35 at the top of the first holder 36 (air F3aa). Then, the air F3aa cooled at the top of the first holder 36 is discharged from the first outlet 32 ​​(air F4).

[0065] Next, we will explain the airflow in the second housing 40. The second fan 44 is positioned at a distance from the second cooling member 45, and as the second fan 44 rotates, air is drawn in from the second air intake port 41 (F1). The second fan 44 changes the direction of the intake air F1 by 90 degrees and discharges the downward-facing F1a. When a portion of the discharged air F1a is brought into contact with the second cooling member 45 at the top of the second holder, a portion of the air F1a is cooled by the second cooling member 45 at the top of the second holder (air F1aa). Then, the cooled air F1aa at the top of the second holder merges with the air F3aa.

[0066] Another portion of the exhausted air F1a (air F1ab) passes to the left of the second holder 46, and the direction of air F1ab is changed by approximately 90 degrees by the second fan 44. Then, the air F1ab comes into contact with the side surface of the second cooling member 45, and further comes into contact with the side surface of the first cooling member 35, and is cooled.

[0067] Then, air F1ab merges with air F10 and is discharged into the garment 200 through the first outlet 32.

[0068] According to the above embodiment, the entire body 51 can be cooled by the cooling members (35, 45). Furthermore, the first cooling member 35 and the second cooling member 45 may be an integrated cooling member rather than being separate components.

[0069] (Embodiment 5) Embodiment 5 is a configuration in which the first cooling member 35 is provided only in the first housing 30. Figure 12 is a schematic cross-sectional view of the blower 130 in Embodiment 5. Embodiment 5 differs from Embodiment 4 in that the air F1a discharged by the second fan 44 is not cooled. The other structural features are the same as in Embodiment 4.

[0070] In addition, although the above description uses a mobile battery to supply power to the aforementioned blower, it is also possible to supply power to the blower by adjusting the voltage from a commercial power outlet such as 100V or 200V.

[0071] In the embodiment described above, the first substrate 10 cools and acts as a cooling section, while the second substrate 12 generates heat and acts as a heating section. By reversing the direction of the current in the Peltier element 9, the heating and cooling aspects can be reversed. In this way, the inside of the clothing 200 can be warmed, and the entire body 51 can be warmed.

[0072] Furthermore, the inventions relating to the above-described embodiments (Embodiments 1 to 5) can be substituted or combined, as long as no contradictions arise.

[0073] As described above, this disclosure includes the blower devices described in the following items.
