Description

[Technical Field]

[0001] The present disclosure relates to a clothing attachment structure for a body air blower intended for clothing such as a jacket, vest, or pants that is worn and is fitted with a body air blower that has a Peltier element disposed within a main body, fins formed on one side of the Peltier element, and a blower fan that blows air to the fins, and that blows temperature-adjusted air that has passed through the fins, either cool air or warm air, and to clothing with a body air blower constructed with this structure. Regarding. [Background technology]

[0002] In recent years, there have been many extremely hot days throughout the year that are uncomfortable for people. On such days, people are encouraged to drink plenty of fluids and use air conditioners appropriately to prevent heatstroke.

[0003] However, due to reasons such as the lack of air conditioning equipment or insufficient cooling, workers working outdoors in extreme heat, workers working in humid indoor environments, and people enjoying recreation, sports, or watching games under the scorching sun cannot cool down with air conditioning.

[0004] Therefore, in recent years, clothing with air conditioning functions and portable air conditioners have become increasingly popular, primarily for people seeking to escape the heat under these circumstances. Among these air conditioners, air blowers using Peltier elements have also been developed. An example of such an air blower is disclosed in Patent Document 1.

[0005] Patent Document 1 is a technical document disclosed in a patent application by the present applicant. The body blower disclosed in Patent Document 1 includes a housing, a Peltier element inside the housing, cooling fins formed on one surface of the Peltier element, heat dissipation fins formed on the other surface opposite to the one surface, and a blower fan that blows air to the cooling fins and the heat dissipation fins. Further, the body blower includes an air intake for taking air into the housing, a cold air outlet for blowing out the cold air that has passed through the cooling fins, a heat dissipation outlet for exhausting the hot air that has passed through the heat dissipation fins, a first flange of the heat dissipation outlet, and a second flange of the cold air outlet.

[0006] In Patent Document 1, the second flange is inserted into an opening inside a pocket of clothing, and a reinforcing member is attached between the inner and outer peripheral surfaces of the opening and the second flange. At the same time, in Patent Document 1, the first flange is inserted into an opening outside the pocket of clothing, and by attaching a reinforcing member between the inner and outer peripheral surfaces of the opening and the first flange, the body blower can be attached to the clothing.

[0007] In the body blower attached to the clothing, by the blower fan, air is taken into the housing from the air intake, and heat exchange occurs between this air and the cooling fins until the air passes through the cooling fins. The air that has passed through the cooling fins is cooled compared to the state before passing through the cooling fins and becomes cold air, which is blown out to the outside from the cold air outlet. Thereby, the body blower attached to the clothing can cool the body of the wearer with the cold air blown out.

Summary of the Invention

Problems to be Solved by the Invention

[0009] In the technology of Patent Document 1, there are the following problems. The first problem is that, for example, since it is necessary to insert a flange through each opening on the outer side and the inner side of the pocket and attach and detach the inner and outer peripheral surfaces of the opening, it takes time and effort to attach the body blower to the clothing, and it is not user-friendly. Furthermore, the second problem is that, for example, since it is not a structure in which the inner and outer peripheral surfaces of the opening are sandwiched by a flange and the body blower is attached to the clothing, there is a risk that the fabric of the clothing will be pulled during work and the body blower will come off the clothing.

[0010] The present disclosure has been made to solve the above problems, and an object thereof is to provide a structure for attaching a body blower to clothing that facilitates attachment of the body blower to the fabric forming the clothing and prevents the body blower from coming off the fabric forming the clothing due to an unexpected situation, and a piece of clothing with a body blower.

Means for Solving the Problems

[0011] In an aspect of the present disclosure made to solve the above problems, there is provided a body blower device having a main body portion formed with an air outlet, a Peltier element disposed in an internal space of the main body portion, a fin unit having first fins, and a blower fan that blows air to the first fins formed on one surface of the Peltier element. The body blower device sends out temperature-controlled air, which is either cold air or warm air that has passed from the upstream side to the downstream side through the first fins, into the clothing from the air outlet. In a clothing attachment structure of the body blower device for attaching the body blower device to the fabric forming the clothing, an insertion hole is formed in the fabric for detachably attaching the body blower device to the fabric. The main body portion has a surface formed with a plurality of openings on the opposite side of the one surface of the Peltier element, and the body blower device includes a plurality of fixing members that can be attached from the surface side. Each of the fixing members has a connecting portion that can be connected to the opening and a sandwiching surface for sandwiching the surface and the fabric. Each of the openings has a connected portion that can be connected to the connecting portion. The body blower device is attached to the fabric by sandwiching the fabric between the surface and the sandwiching surface and connecting the connecting portion of the first fixing member to the connected portion of the first opening and connecting the connecting portion of the second fixing member to the connected portion of the second opening.

[0012] Note that the clothing according to the present disclosure is a general term for a concept including each concept of (a) upper garments such as jackets, jumpers, suits, and vests, (b) undergarments such as pants and trousers, and (c) those worn on the feet and legs such as socks and foot warmers, which are roughly classified into those worn on the feet and legs.

[0013] According to this aspect, by sandwiching the fabric between the surface and the sandwiching surface, connecting the connecting portion of the first fixing member to the connected portion of the first opening, and connecting the connecting portion of the second fixing member to the connected portion of the second opening, the body blower is attached to the fabric forming the clothing. Thereby, for a person, since it is easy to attach the body blower to the fabric forming the clothing, even in a hectic environment, the body blower can be appropriately attached to the fabric forming the clothing. Further, for example, even if the fabric of the clothing worn by a person during work is pulled, since it is attached in a state where the fabric is sandwiched between the surface and the sandwiching surface, it is difficult for the body blower to come off from the clothing. Therefore, for example, even if an unexpected situation occurs during work, the temperature-controlled air can be sent into the clothing from the air outlet of the body blower attached to the fabric forming the clothing to adjust the temperature of the person. Therefore, it is possible to facilitate the attachment of the body blower to the fabric forming the clothing and prevent the body blower from coming off from the fabric forming the clothing due to an unexpected situation.

[0014] In the above aspect, it is preferable that the first opening is an intake portion in which an intake port for sucking air into the internal space of the main body portion is formed, and the second opening is an exhaust portion in which an exhaust port for exhausting air to the outside of the main body portion is formed.

[0015] According to this aspect, by sandwiching the fabric between the surface and the sandwiching surface, connecting the connecting portion of the first fixing member to the connected portion having the intake portion, and connecting the connecting portion of the second fixing member to the connected portion having the exhaust portion, the body blower is attached to the fabric forming the clothing. Thereby, air is sucked from the intake portion of the body blower attached to the fabric forming the clothing into the internal space of the main body portion, and air is exhausted from the exhaust portion of the body blower to the outside of the main body portion. Therefore, while fulfilling the respective roles of the intake portion and the exhaust portion, for example, even if an unexpected situation occurs during work, it is possible to prevent the body blower from coming off from the fabric forming the clothing.

[0016] In the above aspect, in the first opening, a first outer peripheral wall is formed perpendicular to the surface with respect to a center line passing through the center of the region inside the peripheral wall forming the first opening. In the second opening, a second outer peripheral wall is formed perpendicular to the surface with respect to a center line passing through the center of the region inside the peripheral wall forming the second opening. Connection portions are respectively formed on the outer peripheral surfaces of the first outer peripheral wall and the second outer peripheral wall, and connection portions are respectively formed on the inner peripheral surfaces of the plurality of fixing members. This is preferable.

[0017] According to this aspect, with the fabric sandwiched between the surface and the sandwiching surface, the connection portion on the outer peripheral surface of the first outer peripheral wall vertically provided from the surface with respect to the center line passing through the center of the region inside the peripheral wall forming the intake portion is connected to the connection portion on the inner peripheral surface of the first fixing member. At the same time, by connecting the connection portion on the outer peripheral surface of the second outer peripheral wall vertically provided from the surface with respect to the center line passing through the center of the region inside the peripheral wall forming the exhaust portion to the connection portion on the inner peripheral surface of the second fixing member, the body blower is attached to the fabric forming the clothing. Thereby, not only can the body blower be attached to the fabric forming the clothing by the first outer peripheral wall, but also the air from the outside of the main body portion is brought into contact with the first outer peripheral wall, making it easier for the air to flow into the internal space of the main body portion. Therefore, it is possible to easily intake air from the outside of the main body portion into the internal space of the main body portion. Furthermore, not only can the body blower be attached to the fabric forming the clothing by the second outer peripheral wall, but also the air from the internal space of the main body portion is brought into contact with the second outer peripheral wall, making it difficult for the air to flow toward the wearer side. Thereby, it is possible to prevent the air exhausted from the internal space of the main body portion to the outside of the main body portion from staying on the wearer side. Therefore, the efficiency of temperature adjustment by the temperature-adjusted air sent out from the air outlet of the body blower can be enhanced, and comfort can be provided to the wearer by the temperature adjustment.

[0018] In the above aspect, in the internal space of the main body portion, a blowing region of the temperature-adjusted air is provided between the downstream side of the fin unit and the air outlet, and in the blowing region, a reflux inlet portion communicating with a return flow path capable of refluxing the temperature-adjusted air to the upstream side of the first fin is preferably formed.

[0019] According to this aspect, the temperature-controlled air after adjustment can be refluxed from the reflux inlet portion through the return flow path to the upstream side of the first fin and supplied to the first fin again. Therefore, the temperature-controlled air after adjustment including the refluxed temperature-controlled air after adjustment will blow out from the air outlet. It is also assumed that this body air blower is used in an environment where the ambient temperature surrounding the body air blower according to the present disclosure and the temperature of the temperature-controlled air after adjustment to be blown are greatly different by a temperature difference of more than a dozen degrees Celsius as an example. Even in such a case, due to the existence of the return flow path, the temperature-controlled air after adjustment blown out from the air outlet can be temperature-adjusted from the start of blowing and blown at a temperature change rate several times or more that of, for example, a conventional body air blower without a return flow path until it reaches the desired temperature. Thereby, for example, the temperature inside the clothing worn by an operator in an environment where the temperature difference is more than a dozen degrees Celsius and greatly different can be adjusted early.

[0020] In the above aspect, it is preferable that a reflux outlet portion communicating with and connected to the return flow path is formed on the upstream side of the first fin in the internal space of the main body portion, and at the reflux outlet portion, the air and the refluxed temperature-controlled air after adjustment merge.

[0021] According to this aspect, the temperature-controlled air after adjustment refluxed to the upstream side of the first fin can be sent to the first fin again by the flow of the newly introduced air from the air inlet. Therefore, there is no need for a sending means for sending the refluxed temperature-controlled air after adjustment toward the first fin, and the refluxed temperature-controlled air after adjustment can pass through the first fin by the flow of the newly introduced air. Thereby, for example, the temperature inside the clothing worn by an operator in an environment where the temperature difference is more than a dozen degrees Celsius and greatly different can be adjusted earlier.

[0022] In the above aspect, it is preferable that an air direction adjusting portion that divides the flow of the temperature-controlled air after adjustment into the reflux inlet portion side and the air outlet side is provided in the air blowing region.

[0023] According to this aspect, the temperature-controlled air that has reached the air supply area can be reliably separated into a reflux path leading to the reflux inlet and an air supply path leading to the air supply port. Therefore, the temperature-controlled air that has flowed into the reflux path flows back through the return flow path and is returned to the upstream side of the first fin. On the other hand, the temperature-controlled air that has flowed into the air supply path is blown out to the outside from the air supply port. In this way, since the air direction adjustment unit can appropriately adjust the flow of the temperature-controlled air, for example, the temperature inside the clothing worn by an operator in an environment with a large deviation of more than a dozen degrees Celsius can be appropriately adjusted.

[0024] In the above aspect, at the branch point of the air direction adjustment unit, if the flow path cross-sectional area of the temperature-controlled air flowing on the reflux inlet side is the first flow path cross-sectional area Sr, the flow path cross-sectional area of the temperature-controlled air flowing on the air supply port side is the second flow path cross-sectional area Se, and the sum of the first flow path cross-sectional area Sr and the second flow path cross-sectional area Se is the total flow path cross-sectional area S, it is preferable that the ratio k (%) of the first flow path cross-sectional area Sr to the total flow path cross-sectional area S is 0 < k ≤ 50.

[0025] The body air blower according to the present disclosure can ensure that the air volume of the temperature-controlled air blown out from the air supply port is not significantly reduced and has no adverse effects on the user. In addition, the body air blower according to the present disclosure can also adjust the temperature of the blown-out temperature-controlled air to a temperature close to the desired temperature in a shorter time from the start of air supply. According to this aspect, with the temperature-controlled air in which the flow rate and temperature of the temperature-controlled air are harmoniously balanced, for example, the temperature inside the clothing worn by an operator in an environment with a large deviation of more than a dozen degrees Celsius can be appropriately adjusted.

[0026] In the above aspect, it is preferable that the fin unit has second fins formed on the opposite surface of the one surface of the Peltier element, and the air supply fan sends the air to the second fins together with the first fins.

[0027] According to this aspect, in the Peltier element, on one side and the opposite side, it is possible to suppress the deterioration of the cooling efficiency and the heat generation efficiency over time. Therefore, the temperature-controlled air can be continuously blown out at a stable temperature. As a result, for example, in an environment where there is a large deviation with a temperature difference of more than a dozen degrees Celsius, the temperature inside the clothing worn by an operator can be stably adjusted by the temperature-controlled air.

[0028] It is preferable that the body air blower having the clothing attachment structure of the body air blower according to the above aspect is a clothing with a body air blower detachably attached to the clothing.

[0029] According to this aspect, it becomes easy to attach the body air blower to the clothing with a body air blower adopting the clothing attachment structure of the body air blower according to the present disclosure, and it is possible to provide a wearer with a clothing with a body air blower that can prevent the body air blower from coming off the clothing in an unexpected situation.

Effect of the Invention

[0030] Therefore, according to the clothing attachment structure of the body air blower and the clothing with a body air blower according to the present disclosure, there is an excellent effect of providing a clothing attachment structure of the body air blower that facilitates the attachment of the body air blower to the fabric forming the clothing and prevents the body air blower from coming off the fabric forming the clothing in an unexpected situation, and a clothing with a body air blower.

FIG. 3 is a front view of the inner surface of the temperature-adjusting vest when the body blower is not attached as seen from the front body side. FIG. 4 is a front view of the inner surface of the temperature-adjusting vest shown in FIG. 1 as seen from the front body side. Note that, in this embodiment, the clothing with a body blower according to the present disclosure is referred to as the temperature-adjusting vest 1. The body blower according to the present disclosure is referred to as the body blower 20 in this embodiment.

[0035] As shown in FIGS. 1 to 4, the temperature-adjusting vest 1 includes a vest body 2, a body blower 20, and the like. In this embodiment, there is one body blower 20 as an example.

[0036] <Regarding the vest body 2> First, the vest body 2 will be described with reference to FIGS. 1 to 4. As shown in FIGS. 1 to 2, the vest body 2 is formed in the form of a vest (work clothes without cuffs) having a front body 4 and a back body 5. However, this temperature-adjusting vest 1 may be work clothes with long sleeves, short sleeves, or the like.

[0037] In the vest body 2, the fabric 3 is formed in a vest shape by a front-side fabric 3A and a back-side fabric 3B. Both the front-side fabric 3A and the back-side fabric 3B are made of synthetic resin fibers excellent in heat resistance, strength, and transpiration, such as nylon and polyester, for example. However, it is not limited to this, and both the front-side fabric 3A and the back-side fabric 3B may be made of leather. The vest body 2 is provided with a collar part 6 that forms a neckline where the wearer's neck is located when worn at the upper part. At the left and right positions of the vest body 2, there are provided sleeve holes 7 (7A, 7B) through which the wearer's arms pass when worn. Note that the first sleeve hole 7A is a sleeve hole through which the wearer's left arm passes when worn. The second sleeve hole 7B is a sleeve hole through which the wearer's right arm passes when worn.

[0038] As shown in Fig. 1, on the front fabric 3A of the vest body 2, storage parts 8 (first storage part 8A, second storage part 8B), which are pockets for example, are provided. The first storage part 8A and the second storage part 8B are provided in the internal space formed between the front fabric 3A and the back fabric 3B.

[0039] When the fastener (not shown) provided on the front body 4 of the temperature adjustment vest 1 is opened, as shown in Figs. 3 and 4, the entire back fabric 3B of the back body 5 of the vest body 2 can be confirmed when viewed from the front body 4 side. It is configured like this.

[0040] As shown in Figs. 3 and 4, the attachment parts 10 to which the body blower 20 can be attached are located below the collar part 6 in the back body 5 of the temperature adjustment vest 1, and are provided at two locations near the area 9 between the left scapula and the right scapula. However, it is not limited to this. For example, the attachment parts 10 may be provided at two locations on the waist in the back body 5 of the temperature adjustment vest 1. In addition, for example, the attachment parts 10 may be provided at two locations on the chest or abdomen of the front body 4 of the temperature adjustment vest 1.

[0041] As shown in Fig. 3, the attachment part 10 has an insertion hole 11 formed in the attachment part 10 and an outer peripheral edge part 12 around this insertion hole 11. Note that the attachment part 10 is sewn from above the back fabric 3B. The insertion hole 11 is a hole for detachably attaching the body blower 20. As shown in Fig. 3, the attachment part 10 is made of a material with higher rigidity (for example, leather) than the back fabric 3B and is composed of a fabric that does not allow air to pass through. Note that the attachment part 10 may be composed of a fabric such as rubber or resin. As a result, a part of the temperature-adjusted air FL, FLr sent out from the air outlet 30B of the body blower 20 is guided toward the collar part 6 without passing through the attachment part 10.

[0042] <Overview of the body blower 20> First, the overview of the body blower 20 according to the present embodiment will be briefly described with reference to Figs. 5 to 10.

[0049] As shown in FIG. 5, the intake part 26 has an intake part surface 26A in which a plurality (for example, 32) of intake ports 26B are formed, and an intake part outer peripheral wall 27 surrounding the outer periphery of the intake part surface 26A. The plurality (for example, 32) of intake ports 26B are openings for sucking air from the outside of the main body part 22 into the internal space 22S of the main body part 22. As shown in FIG. 6, the intake part outer peripheral wall 27 is vertically provided from the surface 25 to one side in the X-axis direction (lower left side in FIGS. 6 and 11) with respect to a center line AX1 passing through the center of the intake part surface 26A inside the peripheral wall forming the intake part 26. For example, the intake port 26B corresponds to the intake port according to the present disclosure. For example, the intake part outer peripheral wall 27 corresponds to the first outer peripheral wall according to the present disclosure, and for example, the outer peripheral surface 27A of the intake part outer peripheral wall 27 corresponds to the outer peripheral surface of the first outer peripheral wall.

[0050] As shown in FIG. 5, the exhaust portion 28 has an exhaust portion surface 28A formed with a plurality (for example, seven) of exhaust ports 28B, and an exhaust portion outer peripheral wall 29 surrounding the outer periphery of the exhaust portion surface 28A. The plurality (for example, seven) of exhaust ports 28B are openings for exhausting air from the internal space 22S of the main body portion 22 to the outside of the main body portion 22. As shown in FIG. 6, the exhaust portion outer peripheral wall 29 is vertically provided on one side in the X-axis direction (lower left side in FIGS. 6 and 11) from the surface 25 with respect to the center line AX2 passing through the center of the exhaust portion surface 28A inside the peripheral wall forming the exhaust portion 28.

As a result, the temperature-adjusted air FL, FLr sent out from the blower ports 30B formed on the blower portion surface 30A of the body blower 20 attached to the temperature adjustment vest 1 can flow not only toward the back of the wearer HM but also toward the collar portion 6. For example, the blower port 30B corresponds to the blower port according to the present disclosure.

[0053] Also, as will be described in detail later, a reflux system 70 is formed in the main body portion 22 as shown in FIGS. 5 to 8.

[0054] <Regarding the intake portion outer peripheral wall 27 and the exhaust portion outer peripheral wall 29> Next, the intake portion outer peripheral wall 27 and the exhaust portion outer peripheral wall 29 will be described with reference to FIG. 9. In the body blower 20 shown in FIG. 9, in FIG. 9, a central direction L is defined along a center line AX1 passing through the center of the intake portion surface 26A inside the peripheral wall forming the intake portion 26 and a center line AX2 passing through the center of the exhaust portion surface 28A inside the peripheral wall forming the exhaust portion 28. Further, the upper side in the vertical direction of the central direction L is defined as the upper side Lp, the lower side as the lower side Lw, the circumferential direction as the circumferential direction CR, and the reverse circumferential direction as the ACR, and each direction is defined. Also in each of FIGS. 12 to 15, the directions are in accordance with those defined in FIG. 9.

[0055] As shown in FIG. 9, a fixed rail 31 is provided on the outer peripheral surface 27A of the intake portion outer peripheral wall 27. As shown in FIG. 9, the fixed rail 31 faces the surface 25 side, and a plurality (for example, 4) of the fixed rail 31 are provided at different positions in the circumferential direction of the center line AX1 of the intake portion surface 26A between one end 31a and the other end 31b (see FIGS. 11 and 12). As shown in FIG. 9, mounting groove portions 35 are respectively provided between the plurality of fixed rails 31 and the first plate portion 23a. The plurality (for example, 4) of mounting groove portions 35 are provided along the circumferential direction CR of the intake portion surface 26A. The fixed rails 31 adjacent to each other in the circumferential direction CR are arranged at the same height in the central direction L (see FIGS. 9 and 12). As shown in FIG. 9, the four fixed rails 31 are each provided with a gap 34 between the intermittently adjacent fixed rails 31. A plurality (for example, 4) of gaps 34 are provided in the intake portion outer peripheral wall 27. As shown in FIG. 9, the gap 34 is connected to the mounting groove portion 35. For example, the fixed rail 31 corresponds to the connected portion according to the present disclosure.

[0056] As shown in FIG. 9, a fixed rail 31 is provided on the outer peripheral surface 29A of the outer peripheral wall 29 of the exhaust portion. As shown in FIG. 9, the fixed rail 31 is provided on the surface 25 side, and a plurality (for example, 4) of the fixed rails 31 are provided at different positions in the circumferential direction of the center line AX2 of the exhaust portion surface 28A between one end 31a and the other end 31b (see FIGS. 11 and 12). As shown in FIG. 9, mounting groove portions 35 are respectively provided between the plurality of fixed rails 31 and the first plate portion 23a. The plurality (for example, 4) of mounting groove portions 35 are provided along the circumferential direction CR of the exhaust portion surface 28A. The fixed rails 31 adjacent to each other in the circumferential direction CR are arranged at the same height in the central direction L (see FIGS. 9 and 12). As shown in FIG. 9, the four fixed rails 31 are respectively provided with gaps 34 between the intermittently adjacent fixed rails 31. A plurality (for example, 4) of gaps 34 are provided in the outer peripheral wall 29 of the exhaust portion. As shown in FIG. 9, the gap 34 is connected to the mounting groove portion 35.

[0057] As shown in FIG. 9, a plurality of ring fasteners 50 (first ring fastener 50A, second ring fastener 50B) are formed so as to be freely fastened or released from the outer peripheral surface 27A of the intake portion outer peripheral wall 27 and the outer peripheral surface 29A of the exhaust portion outer peripheral wall 29. The plurality of ring fasteners 50 (first ring fastener 50A, second ring fastener 50B) can be mounted from the surface 25 side and can engage with the intake portion 26 and the exhaust portion 28. The plurality of ring fasteners 50 (first ring fastener 50A, second ring fastener 50B) are made of synthetic resin and are provided with an annular outer flange 51 formed in a substantially polygonal shape. As shown in FIG. 9, the outer flange 51 is formed with 12 elliptical holes. The inner diameters of the plurality of ring fasteners 50 (first ring fastener 50A, second ring fastener 50B) are larger than the outer diameters of the intake portion outer peripheral wall 27 and the exhaust portion outer peripheral wall 29. The plurality of ring fasteners 50 (first ring fastener 50A, second ring fastener 50B) have a sandwiching surface 52 that sandwiches the back lining 3B and the outer peripheral edge 12 facing the surface 25 on the side opposite to the surface where the 12 elliptical holes are formed. Note that the sandwiching surface 52 is a surface for sandwiching the surface 25, the back lining 3B, and the outer peripheral edge 12.

[0058] On the inner circumferential surfaces of a plurality of ring fasteners 50 (first ring fastener 50A, second ring fastener 50B), projections 54 that can be connected to respective ones of the plurality of fixed rails 31 are provided. A plurality of projections 54 (for example, four) are provided at intervals in the circumferential direction CR on the plurality of ring fasteners 50 (first ring fastener 50A, second ring fastener 50B). Each of the plurality of projections 54 can engage with each of a plurality of restricting portions 32 of the plurality of fixed rails 31. Adjacent projections 54 in the circumferential direction CR are arranged at the same height in the central direction L. The plurality of projections 54 are inclined toward the clamping surface 52 side with respect to a virtual surface orthogonal to the center line AX1 of the intake portion surface 26A and the center line AX2 of the exhaust portion surface 28A, and the inclination angle θ2 is 3°. Thereby, each of the plurality of projections 54 is easily connectable to each of the plurality of fixed rails 31. For example, the projection 54 corresponds to the connection portion according to the present disclosure.

[0059] <Regarding the blower fan 45> Next, the blower fan 45 will be described. The blower fan 45 blows air toward the heat sink unit 42. As shown in FIG. 6, in the present embodiment, the blower fan 45 is a type of centrifugal fan and is a multi-blade blower (squirrel-cage fan) having a suction capacity. The squirrel-cage fan has a substantially cylindrical shape in which a plurality of blades are annularly arranged along the circumferential direction with respect to the central axis of rotation, and sucks in air along the central axis and blows it out in the radially outward direction between the rotating blades. For example, the blower fan 45 corresponds to the blower fan according to the present disclosure.

[0060] The blower fan 45 has an intake introduction portion 48 between the blade 46 and the drive portion 47. Air is taken into the intake introduction portion 48 from the intake port 26B. The blower fan 45 is arranged in the internal space 22S of the main body portion 22 in accordance with the position of the intake port 26B, and the outer periphery of the blade 46 is surrounded by the fan outer peripheral wall 49.

[0061] By the way, unlike axial fans such as propeller fans and turbo fans, the sirocco fan is less affected by disturbances such as the direction and strength of the wind on the sucked air, and uses the centrifugal force acting on the sucked air to blow air, so the noise during operation is also small.

[0062] On the other hand, since the sirocco fan blows air by utilizing the centrifugal force acting on the sucked air due to the rotation of a plurality of blades, generally, the wind force of the air blown by the sirocco fan is smaller than that of axial fans such as propeller fans and turbo fans. Therefore, in the internal space 22S of the body air blowing device 20 according to the present embodiment, the main body 22 is provided with a width-reducing flow path 63 formed by the fan outer peripheral wall 49 between the blower fan 45 and the Peltier element unit 40.

[0063] In the width-reducing flow path 63, the flow path width n (0 < n) of the air blown by the blower fan 45, that is, the temperature-adjusted air flow FL, is narrower than the flow path width m (0 < n < m) of the air flow passing through the rotation center axis O of the blower fan 45 so that the wind force due to the blowing pressure, flow velocity, etc. becomes larger.

[0064] As an example, the ratio of the flow path width n to the flow path width m is preferably in the range of 25% or more and 75% or less. This is because the wind force blown by the blower fan 45 can be increased, and the air blown by the blower fan 45 can be evenly delivered to the two Peltier element units 40, achieving a well-balanced harmony.

[0065] <Regarding the Peltier element unit 40> Next, the Peltier element unit 40 will be described. As shown in FIG. 6, two Peltier element units 40 are arranged in the main body 22. As described above, the Peltier element unit 40 includes a Peltier element 41, a heat sink unit 42, and a fin cover 44.

[0066] As shown in FIG. 10, the Peltier element 41 is a kind of plate-shaped semiconductor thermoelectric element having one surface 41a and the other surface 41b on the opposite side thereof. The Peltier element 41 is electrically connected to the control unit 21 and a power source (not shown) via a power supply port 36 (see FIG. 19). For example, one surface 41a of the Peltier element 41 corresponds to one surface of the Peltier element according to the present disclosure, and for example, the other surface 41b of the Peltier element 41 corresponds to the opposite surface of the Peltier element according to the present disclosure.

[0067] When a direct current is supplied from the power source to the Peltier element 41, due to the Peltier effect, one surface 41a absorbs heat and enters a state of heat absorption (cooling surface), and at the same time, the other surface 41b generates heat and enters a state of heat generation (heating surface). Further, when the direction of the supplied direct current is reversed by the control unit 21, in the Peltier element 41, the other surface 41b absorbs heat and enters a state of heat absorption (cooling surface), and at the same time, one surface 41a generates heat and enters a state of heat generation (heating surface).

[0068] That is, in the Peltier element 41, when the control unit 21 reverses the direction of the direct current supplied to the Peltier element 41, the cooling surface and the heating surface are interchanged between the one surface 41a and the other surface 41b.

[0069] The Peltier element 41 has, for example, a characteristic of absorbing and generating heat simultaneously at a temperature having a relative temperature difference from the outside air temperature within a temperature range of about 20 to 50°C. That is, for example, when the Peltier element 41 absorbs and generates heat under an outside air temperature of 35°C in summer, the cooling surface exhibits heat of 15 to -15°C, and this heat becomes the cold heat for cooling the body. At the same time, the heating surface exhibits heat of 55 to 85°C, and this heat becomes the exhaust heat.

[0070] On the other hand, when the Peltier element 41 absorbs and generates heat under an outside air temperature of 5°C in winter, the cooling surface exhibits heat of -15 to -45°C, and this heat becomes the exhaust heat. At the same time, the heating surface exhibits heat of 25 to 55°C, and this heat becomes the warm heat for warming the body.

[0071] In this embodiment, as an example, a Peltier element 41 having a temperature characteristic of generating heat simultaneously with heat absorption within a temperature range of about 20 to 50°C in comparison with the outside air temperature is given.

[0072] However, the Peltier element is not limited to the temperature characteristics given in this embodiment. As long as it has a temperature characteristic that can cool the body to such an extent that frostbite is not incurred and warm the body to such an extent that burns are not incurred by the temperature-controlled rear wind FL described later, it may be configured with appropriate changes. As an example, the temperature characteristic of the Peltier element has a temperature range of about 10 to 40°C or a temperature range of about 10 to 20°C in comparison with the outside air temperature.

[0073] As shown in FIG. 10, the heat sink unit 42 is composed of a blower-side heat sink 42A and an exhaust-side heat sink 42B. The blower-side heat sink 42A corresponds to the first fin according to the present disclosure, and the exhaust-side heat sink 42B corresponds to the second fin according to the present disclosure. The blower-side heat sink 42A and the exhaust-side heat sink 42B are a pair.

[0074] The blower-side heat sink 42A is formed in a size that can contact almost the entire surface of one surface 41a of the Peltier element 41, and is formed by standing upright from a flat plate portion 42Aa with a countless number of fins formed by being folded back in a substantially corrugated shape, with a gap provided between adjacent fins.

[0075] The exhaust-side heat sink 42B is formed in a size that can contact almost the entire surface of the other surface 41b of the Peltier element 41, and is formed by standing upright from a flat plate portion 42Ba with a countless number of fins formed by being folded back in a substantially corrugated shape, with a gap provided between adjacent fins.

[0076] In the Peltier element unit 40, as shown in FIG. 10, the surface of the flat plate portion 42Aa of the blower-side heat sink 42A and one surface 41a of the Peltier element 41 are arranged to face each other in surface contact with each other. Also, the surface of the flat plate portion 42Ba of the exhaust-side heat sink 42B and the other surface 41b of the Peltier element 41 are arranged to face each other in surface contact with each other.

[0077] However, strictly speaking, due to the accuracy difference between the surface shape of the flat plate portion 42Aa of the blower-side heat sink 42A and the surface shape of one surface 41a of the Peltier element 41, there is a slight gap (void) between the surface of the flat plate portion 42Aa and the one surface 41a. Similarly, due to the accuracy difference between the surface shape of the flat plate portion 42Ba of the exhaust-side heat sink 42B and the surface shape of the other surface 41b of the Peltier element 41, there is a slight gap (void) between the surface of the flat plate portion 42Ba and the other surface 41b.

[0078] Therefore, a grease layer 43 that fills such voids with grease is interposed between the Peltier element 41 and the blower-side heat sink 42A, and between the Peltier element 41 and the exhaust-side heat sink 42B. As an example, the grease has a relatively high thermal conductivity, such as at least satisfying a thermal conductivity of 5 W / m·K, and has a property of maintaining a relatively high viscosity within a temperature range up to around 0 to 100°C.

[0079] By providing the grease layer 43, the heat generated in the Peltier element 41 is transferred to the heat sink unit 42 while suppressing heat transfer loss at the one surface 41a and the other surface 41b.

[0080] Note that the body blower 20 according to the present embodiment is in a mode in which two Peltier element units 40 are juxtaposed. However, the number of Peltier element units having a Peltier element, a first fin, and a second fin is not limited to two, and can be variously changed, for example, in the case of one, or in the case of three or more.

[0081] Also, the body blower 20 according to the present embodiment is in a mode in which two Peltier element units 40 are juxtaposed, and each of the two Peltier elements exhibits heat absorption and heat generation. On the other hand, the Peltier element unit can also be configured by using one large Peltier element, for example, to the same extent as when using two small Peltier elements, in terms of its heat absorption characteristics and heat generation characteristics.

[0082] However, when comparing the case of the first condition using one large Peltier element with the case of the second condition using two small Peltier elements, in some cases, the second condition has a better response in terms of the heat absorption and heat generation occurring in the Peltier elements than the first condition. Therefore, the body blower 20 according to the present embodiment is configured in a manner where two Peltier element units 40 are juxtaposed.

[0083] Further, as shown in FIG. 10, the Peltier element unit 40 is configured in a manner that the fin cover 44 surrounds the entire periphery of the air supply side heat sink 42A and the exhaust side heat sink 42B in contact with the Peltier element 41.

[0084] <Regarding the mounting of the body blower 20> The mounting of the body blower 20 on the temperature adjustment vest 1 will be described with reference to FIG. 11. FIG. 11 is an explanatory diagram showing a method of mounting the body blower on the temperature adjustment vest.

[0085] As shown in FIG. 11, when mounting the body blower 20, a person inserts the outer peripheral wall 27 of the intake part of the body blower 20 from the inner side 10a of the mounting part 10 into the insertion hole 11 formed in the mounting part 10 and the clothing insertion hole 3C of the back clothing 3B. As shown in FIG. 11, when mounting the body blower 20, a person inserts the outer peripheral wall 29 of the exhaust part of the body blower 20 from the inner side 10a of the mounting part 10 into the insertion hole 11 formed in the mounting part 10 and the clothing insertion hole 3C of the back clothing 3B.

[0086] Subsequently, with the outer peripheral wall 27 of the intake part and the outer peripheral wall 29 of the exhaust part arranged in the insertion hole 11 and the clothing insertion hole 3C of the back clothing 3B, the person brings the surface 25 into contact with the outer peripheral edge part 13. As a result, the outer peripheral wall 27 of the intake part and the outer peripheral wall 29 of the exhaust part are respectively arranged in the insertion hole 11 and the clothing insertion hole 3C of the back clothing 3B with the surface 25 in contact with the outer peripheral edge part 13.

[0087] Subsequently, the person first inserts the outer peripheral wall 27 of the intake portion inside the first ring fastener 50A, and inserts each of the plurality of protrusions 54 of the first ring fastener 50A into each of the plurality of gaps 34 on the outer peripheral surface 27A of the outer peripheral wall 27 of the intake portion. As a result, the back fabric 3B and the outer peripheral edge portion 12 are in a state of being sandwiched between the surface 25 and the outer flange 51 of the first ring fastener 50A.

[0088] Subsequently, the person relatively rotates the main body portion 22 and the first ring fastener 50A in the circumferential direction CR of the intake portion surface 26A, so that each protrusion 54 enters the mounting groove portion 35 on the outer peripheral surface 27A of the outer peripheral wall 27 of the intake portion from one end 31a of the fixed rail 31. Further, the person relatively rotates the main body portion 22 and the first ring fastener 50A in the circumferential direction CR of the intake portion surface 26A, so that each protrusion 54 slides along the circumferential direction CR of the intake portion surface 26A on each fixed rail 31. Subsequently, the person relatively rotates the main body portion 22 and the first ring fastener 50A in the circumferential direction CR of the intake portion surface 26A, and causes the plurality of protrusions 54 to overcome the plurality of restricting portions 32 respectively disposed thereon. When each of the plurality of protrusions 54 has overcome each of the plurality of restricting portions 32, the plurality of restricting portions 32 restrict the movement of the plurality of protrusions 54 in the anti-circumferential direction ACR of the intake portion surface 26A. The protrusion 54 that has overcome the restricting portion 32 and stopped moving is fixed by being in surface contact and engaging with the restricting portion 32. As a result, the back fabric 3B and the outer peripheral edge portion 12 are fixed in a state of being sandwiched between the surface 25 and the outer flange 51.

[0089] Next, the person inserts the outer peripheral wall 29 of the exhaust portion inside the second ring fastener 50B, and inserts each of the plurality of protrusions 54 of the second ring fastener 50B into each of the plurality of gaps 34 on the outer peripheral surface 29A of the outer peripheral wall 29 of the exhaust portion. As a result, the back fabric 3B and the outer peripheral edge portion 12 are in a state of being sandwiched between the surface 25 and the outer flange 51 of the second ring fastener 50B.

[0090] Subsequently, the person rotates the main body 22 and the second ring fastener 50B relative to each other in the circumferential direction CR of the exhaust portion surface 28A, causing the respective protrusions 54 to enter the mounting groove portions 35 on the outer peripheral surface 29A of the outer peripheral wall 29 of the exhaust portion from one end 31a of the fixed rail 31. Further, the person rotates the main body 22 and the second ring fastener 50B relative to each other in the circumferential direction CR of the exhaust portion surface 28A, causing the respective protrusions 54 to slide along the circumferential direction CR of the exhaust portion surface 28A over the respective fixed rails 31. Subsequently, the person continues to rotate the main body 22 and the second ring fastener 50B relative to each other in the circumferential direction CR of the exhaust portion surface 28A, causing the plurality of protrusions 54 to overcome the restricting portions 32 provided respectively for the plurality of them. When each of the plurality of protrusions 54 has overcome each of the plurality of restricting portions 32, the plurality of restricting portions 32 restrict the movement of the plurality of protrusions 54 in the anti-circumferential direction ACR of the exhaust portion surface 28A. The protrusions 54 that have overcome the restricting portions 32 and stopped moving are fixed by coming into surface contact and engaging with the restricting portions 32. Thereby, the back fabric 3B and the outer peripheral edge portion 12 are fixed in a state of being sandwiched between the surface 25 and the outer flange 51.

[0091] As shown in FIG. 2, the body blower 20 is mounted near 9 between the left scapula and the right scapula, below the collar edge portion 6 at the back 5 of the temperature-adjusting vest 1. In this case, cold air or warm air is sent out from the air outlet 30B toward the collar edge portion 6 (see FIG. 23). Thereby, the cold air or warm air sent out from the air outlet 30B can, for example, cool or warm the neck muscles of the wearer HM.

[0092] <Regarding the fixed rail 31> With reference to FIG. 12, a plurality of fixed rails 31 provided on the outer peripheral wall 27 of the intake portion and the outer peripheral wall 29 of the exhaust portion will be described. FIG. 12 is a developed view in which the outer peripheral surface of the outer peripheral wall of the intake portion and the outer peripheral surface of the outer peripheral wall of the exhaust portion are developed on a plane.

[0093] As shown in FIG. 12, the plurality of fixed rails 31 have sliding surfaces 33 that connect between one end 31a and the other end 31b of each fixed rail 31 and contact the respective protrusions 54 of the plurality of ring fasteners 50. As shown in FIG. 12, a plurality (for example, 4) of regulating portions 32 are provided on each of the sliding surfaces 33 of the plurality of fixed rails 31. Each of the plurality of regulating portions 32 regulates the movement of the plurality of protrusions 54 that move along the sliding surface 33 in the counter circumferential direction ACR of the intake portion surface 26A and the exhaust portion surface 28A. On the sliding surface 33 that connects one end 31a and the other end 31b of each fixed rail 31, the regulating portions 32 are intermittently arranged in the order of the first regulating portion 32a ⇒ the second regulating portion 32b ⇒ the third regulating portion 32c ⇒ the fourth regulating portion 32d.

[0094] As shown in FIG. 12, the plurality of fixed rails 31 are inclined toward the surface 25 side along the center line AX1 of the intake portion surface 26A and the center line AX2 of the exhaust portion surface 28A. All of the plurality of fixed rails 31 in the present embodiment are given an inclination angle θ1 of 3° as an example between one end 31a and the other end 31b. Thereby, all of the plurality of fixed rails 31 in the first embodiment are formed in an inclined manner with a height difference ΔH in the center direction L between one end 31a and the other end 31b.

[0095] <Regarding the thickness of the fabric sandwiched between the surface 25 and the outer flange 51> Using FIGS. 13 to 15, the location where the protrusion 54 is engaged and fixed according to the thickness of the fabric sandwiched between the surface 25 and the outer flange 51 will be described. FIG. 13 is a side view of the body blower, and is an explanatory diagram showing a case where the fixed rail and the protrusion are engaged at the first stage. FIG. 14 is a side view of the body blower, and is an explanatory diagram showing a case where the fixed rail and the protrusion are engaged at the second stage. FIG. 15 is a side view of the body blower, and is an explanatory diagram showing a case where the fixed rail and the protrusion are engaged at the third stage.

[0096] Using FIG. 13, a case will be described where each of the plurality of protrusions 54 overrides the first restricting portion 32a of each fixing rail 31, and the fixing rail 31 and the protrusion 54 engage with each other in the first stage.

[0097] When the thickness of the fabric of the temperature adjustment vest 1 is X1 (for example, about 2.2 mm), with the fabric sandwiched between the surface 25 and the outer flange 51, a person enters the intake portion outer peripheral wall 27 inside the first ring fastener 50A. As a result, each of the plurality of protrusions 54 enters each of the plurality of gaps 34. Subsequently, when the person relatively rotates the main body portion 22 and the ring fastener 50 in the circumferential direction CR of the intake portion surface 26A, each protrusion 54 of the first ring fastener 50A enters the attachment groove portion 35 from one end 31a of the fixing rail 31. Further, when the person relatively rotates the main body portion 22 and the first ring fastener 50A in the circumferential direction CR of the intake portion surface 26A, each of the plurality of protrusions 54 slides along the circumferential direction CR of the intake portion surface 26A on each fixing rail 31. When the main body portion 22 and the first ring fastener 50A are relatively rotated by, for example, 15 degrees along the circumferential direction CR of the intake portion surface 26A, each of the plurality of protrusions 54 overrides each of the plurality of first restricting portions 32a. By each of the overridden first restricting portions 32a, the movement of each protrusion 54 in the anti-circumferential direction ACR of the intake portion surface 26A is restricted. The angle by which the main body portion 22 and the first ring fastener 50A are relatively rotated along the circumferential direction CR of the intake portion surface 26A for each of the plurality of protrusions 54 to override each of the plurality of first restricting portions 32a is not limited to 15 degrees. For example, it is preferably any one of 15 degrees to 20 degrees.

[0098] As shown in FIG. 13, each of the plurality of protrusions 54 where the movement of the intake portion surface 26A in the circumferential direction CR has stopped at the first stage is fixed by surface contact and engagement with each of the plurality of first restricting portions 32a. In this case, the fabric having a thickness of X1 (for example, about 2.2 mm) that forms the temperature adjustment vest 1 is sandwiched between the surface 25 and the outer flange 51. When releasing the attachment of the body blower 20, a person relatively rotates the main body 22 and the first ring fastener 50A by, for example, 15 degrees in the anti-circumferential direction ACR of the intake portion surface 26A, so that each of the plurality of protrusions 54 gets over each of the first restricting portions 32a.

[0099] Subsequently, when the thickness of the fabric that forms the temperature adjustment vest 1 is X1 (for example, about 2.2 mm), with the fabric sandwiched between the surface 25 and the outer flange 51, a person causes the exhaust portion outer peripheral wall 29 to enter inside the second ring fastener 50B. As a result, each of the plurality of protrusions 54 enters each of the plurality of gaps 34. Subsequently, when a person relatively rotates the main body 22 and the second ring fastener 50B in the circumferential direction CR of the exhaust portion surface 28A, each protrusion 54 of the second ring fastener 50B enters from one end 31a of the fixed rail 31 into the attachment groove portion 35. Further, when a person relatively rotates the main body 22 and the second ring fastener 50B in the circumferential direction CR of the exhaust portion surface 28A, each of the plurality of protrusions 54 slides along each fixed rail 31 along the circumferential direction CR of the exhaust portion surface 28A. When the main body 22 and the second ring fastener 50B are relatively rotated by, for example, 15 degrees along the circumferential direction CR of the exhaust portion surface 28A, each of the plurality of protrusions 54 gets over each of the plurality of first restricting portions 32a. By each of the overcome first restricting portions 32a, the movement of each protrusion 54 in the anti-circumferential direction ACR of the exhaust portion surface 28A is restricted. The angle by which the main body 22 and the second ring fastener 50B are relatively rotated along the circumferential direction CR of the exhaust portion surface 28A for each of the plurality of protrusions 54 to get over each of the plurality of first restricting portions 32a is not limited to 15 degrees. For example, it is preferably any one of 15 degrees to 20 degrees.

[0100] As shown in FIG. 13, each of the plurality of protrusions 54 where the movement of the exhaust portion surface 28A in the circumferential direction CR stops at the first stage is fixed by surface contact and engagement with each of the plurality of first restricting portions 32a. In this case, the fabric having a thickness of X1 (for example, about 2.2 mm) that forms the temperature adjustment vest 1 is sandwiched between the surface 25 and the outer flange 51. As a result, as shown in FIG. 13, the body blower 20 is in a state of being attached to the temperature adjustment vest 1. When releasing the attachment of the body blower 20, a person relatively rotates the main body 22 and the second ring fastener 50B by 15 degrees, for example, in the anti-circumferential direction ACR of the exhaust portion surface 28A, so that each of the plurality of protrusions 54 gets over each of the first restricting portions 32a.

[0101] Using FIG. 14, the case where each of the plurality of protrusions 54 gets over the second restricting portion 32b of each of the respective fixing rails 31 and the fixing rail 31 and the protrusion 54 engage with each other at the second stage will be described.

[0102] When the thickness of the fabric that forms the temperature adjustment vest 1 is X2 (for example, about 1.54 mm), with the fabric sandwiched between the surface 25 and the outer flange 51, a person causes the intake portion outer peripheral wall 27 to enter the inside of the first ring fastener 50A. As a result, each of the plurality of protrusions 54 enters each of the plurality of gaps 34. Subsequently, when a person relatively rotates the main body 22 and the ring fastener 50 in the circumferential direction CR of the intake portion surface 26A, each protrusion 54 of the first ring fastener 50A enters the attachment groove portion 35 from one end 31a of the fixing rail 31. Further, when a person relatively rotates the main body 22 and the first ring fastener 50A in the circumferential direction CR of the intake portion surface 26A, each of the plurality of protrusions 54 slides along the circumferential direction CR of the intake portion surface 26A on each of the respective fixing rails 31. When the main body 22 and the first ring fastener 50A are relatively rotated by 15 degrees, for example, along the circumferential direction CR of the intake portion surface 26A, each of the plurality of protrusions 54 gets over each of the plurality of first restricting portions 32a. By each of the got-over first restricting portions 32a, the movement of each protrusion 54 in the anti-circumferential direction ACR of the intake portion surface 26A is restricted.

[0103] Furthermore, when a person rotates the main body portion 22 and the first ring fastener 50A relative to each other by, for example, 15 degrees along the circumferential direction CR of the intake portion surface 26A, each of the plurality of protrusions 54 slides upward and overrides each of the plurality of second regulating portions 32b. By each of the overridden second regulating portions 32b, the movement of each of the protrusions 54 in the anti-circumferential direction ACR of the intake portion surface 26A is regulated. The angle by which the main body portion 22 and the first ring fastener 50A are relatively rotated along the circumferential direction CR of the intake portion surface 26A in order for each of the plurality of protrusions 54 to override each of the plurality of second regulating portions 32b is not limited to 15 degrees. For example, it is preferably either 15 degrees or 20 degrees.

[0104] As shown in FIG. 14, each of the plurality of protrusions 54 that has stopped moving in the circumferential direction CR of the intake portion surface 26A at the second stage is fixed by coming into surface contact and engaging with each of the plurality of second regulating portions 32b. In this case, a fabric having a thickness of X2 (for example, about 1.54 mm) that forms the temperature adjustment vest 1 is sandwiched between the surface 25 and the outer flange 51. When removing the body blower 20, a person relatively rotates the main body portion 22 and the first ring fastener 50A by, for example, 30 degrees in the anti-circumferential direction ACR of the intake portion surface 26A. As a result, each of the plurality of protrusions 54 can override each of the first regulating portion 32a and the second regulating portion 32b.

[0105] Next, when the thickness of the fabric of the temperature regulating vest 1 is X2 (for example, approximately 1.54 mm), the person inserts the exhaust portion outer peripheral wall 29 into the second ring fastener 50B while sandwiching the fabric between the surface 25 and the outer flange 51. As a result, each of the multiple protrusions 54 enters each of the multiple gaps 34. Next, when the person rotates the main body 22 and the second ring fastener 50B relative to each other in the circumferential direction CR of the exhaust portion surface 28A, each of the protrusions 54 of the second ring fastener 50B enters the mounting groove 35 from one end 31a of the fixed rail 31. Furthermore, when the person rotates the main body 22 and the second ring fastener 50B relative to each other in the circumferential direction CR of the exhaust portion surface 28A, each of the multiple protrusions 54 slides on each of the fixed rails 31 along the circumferential direction CR of the exhaust portion surface 28A. When the main body portion 22 and the second ring fastener 50B are rotated relative to each other, for example, by 15 degrees along the circumferential direction CR of the exhaust surface 28A, each of the multiple protrusions 54 climbs over each of the multiple first restriction portions 32a. The movement of each protrusion 54 in the counter-circumferential direction ACR of the exhaust surface 28A is restricted by each of the first restriction portions 32a that it has climbed over.

[0106] Furthermore, when a person rotates the main body 22 and the ring fastener 50 relative to each other along the circumferential direction CR of the exhaust surface 28A, for example, by 15 degrees, each of the multiple protrusions 54 slides over and overcomes each of the multiple second restriction portions 32b. The second restriction portions 32b that each protrusion 54 overcomes restricts movement of the protrusion 54 in the counter-circumferential direction ACR of the exhaust surface 28A. To allow each of the multiple protrusions 54 to overcome each of the multiple second restriction portions 32b, the angle by which the main body 22 and the second ring fastener 50B rotate relative to each other along the circumferential direction CR of the exhaust surface 28A is not limited to 15 degrees. For example, a value between 15 degrees and 20 degrees is preferred.

[0107] As shown in FIG. 14, each of the plurality of protrusions 54 that has stopped moving in the circumferential direction CR of the exhaust section surface 28A at the second stage is fixed by surface contact and engagement with each of the plurality of second restricting portions 32b. In this case, the fabric having a thickness of X2 (for example, about 1.54 mm) made of the temperature adjustment vest 1 is sandwiched between the surface 25 and the outer flange 51. As a result, as shown in FIG. 14, the body blower 20 is in a state of being attached to the temperature adjustment vest 1. When releasing the attachment of the body blower 20, a person relatively rotates the main body portion 22 and the ring fastener 50 by, for example, 30 degrees in the anti-circumferential direction ACR of the exhaust section surface 28A, so that each of the plurality of protrusions 54 gets over each of the first restricting portion 32a and the second restricting portion 32b.

[0108] With reference to FIG. 15, a case will be described in which each of the plurality of protrusions 54 gets over the third restricting portion 32c of each fixing rail 31 and the fixing rail 31 and the protrusion 54 engage with each other at the third stage.

[0109] When the thickness of the fabric made of the temperature adjustment vest 1 is X3 (for example, about 0.89 mm), with the fabric sandwiched between the surface 25 and the outer flange 51, a person makes the intake section outer peripheral wall 27 enter the inside of the first ring fastener 50A. As a result, each of the plurality of protrusions 54 enters each of the plurality of gaps 34. Subsequently, when the person relatively rotates the main body portion 22 and the first ring fastener 50A in the circumferential direction CR of the intake section surface 26A, each protrusion 54 of the first ring fastener 50A enters the attachment groove portion 35 from one end 31a of the fixing rail 31. Further, when the person relatively rotates the main body portion 22 and the first ring fastener 50A in the circumferential direction CR of the intake section surface 26A, each of the plurality of protrusions 54 slides on each fixing rail 31 along the circumferential direction CR of the intake section surface 26A. When the main body portion 22 and the first ring fastener 50A are relatively rotated by, for example, 15 degrees along the circumferential direction CR of the intake section surface 26A, each of the plurality of protrusions 54 gets over each of the plurality of first restricting portions 32a. By each of the overcome first restricting portions 32a, the movement of each protrusion 54 in the anti-circumferential direction ACR of the intake section surface 26A is restricted.

[0110] Further, when a person relatively rotates the main body portion 22 and the first ring fastener 50A along the circumferential direction CR of the intake portion surface 26A by, for example, 15 degrees, each of the plurality of protrusions 54 slides upward and gets over each of the plurality of second restricting portions 32b. By each of the second restricting portions 32b that has been got over, the movement of each of the protrusions 54 in the anti-circumferential direction ACR of the intake portion surface 26A is restricted.

[0111] Further, when a person relatively rotates the main body portion 22 and the ring fastener 50 along the circumferential direction CR of the intake portion surface 26A by, for example, 15 degrees, each of the plurality of protrusions 54 slides upward and gets over each of the plurality of third restricting portions 32c. By each of the third restricting portions 32c that has been got over, the movement of each of the protrusions 54 in the anti-circumferential direction ACR of the intake portion surface 26A is restricted. In order for each of the plurality of protrusions 54 to get over each of the plurality of third restricting portions 32c, the angle by which the main body portion 22 and the first ring fastener 50A relatively rotate along the circumferential direction CR of the intake portion surface 26A is not limited to 15 degrees. For example, it is preferably either 15 degrees or 20 degrees.

[0112] As shown in FIG. 15, each of the plurality of protrusions 54 that has stopped moving in the circumferential direction CR of the intake portion surface 26A at the third stage is fixed by surface-contact engaging with each of the plurality of third restricting portions 32c. In this case, a fabric having a thickness of X3 (for example, about 0.89 mm) of the fabric forming the temperature adjustment vest 1 is sandwiched between the surface 25 and the outer flange 51. When removing the body blower 20, a person relatively rotates the main body portion 22 and the first ring fastener 50A by, for example, 45 degrees in the anti-circumferential direction ACR of the intake portion surface 26A. Thereby, each of the plurality of protrusions 54 can get over each of the first restricting portion 32a to the third restricting portion 32c.

[0113] When each of the plurality of protrusions 54 has overcome the third regulating portion 32c, even if a person relatively rotates the main body portion 22 and the first ring fastener 50A in the circumferential direction CR of the intake portion surface 26A, each of the plurality of protrusions 54 cannot overcome each of the plurality of fourth regulating portions 32d. Thereby, it is possible to prevent the body blower 20 from falling off the temperature adjustment vest 1 due to the relative rotation of the main body portion 22 and the first ring fastener 50A in the circumferential direction CR of the intake portion surface 26A.

[0114] Subsequently, when the thickness of the fabric of the temperature adjustment vest 1 is X3 (for example, about 0.89 mm), with the fabric sandwiched between the surface 25 and the outer flange 51, a person inserts the outer peripheral wall 29 of the exhaust portion inside the second ring fastener 50B. As a result, each of the plurality of protrusions 54 enters each of the plurality of gaps 34. Subsequently, when the person relatively rotates the main body portion 22 and the second ring fastener 50B in the circumferential direction CR of the exhaust portion surface 28A, each protrusion 54 of the second ring fastener 50B enters the mounting groove portion 35 from one end 31a of the fixed rail 31. Further, when the person relatively rotates the main body portion 22 and the second ring fastener 50B in the circumferential direction CR of the exhaust portion surface 28A, each of the plurality of protrusions 54 slides along the circumferential direction CR of the exhaust portion surface 28A on each fixed rail 31. When the main body portion 22 and the second ring fastener 50B are relatively rotated by, for example, 15 degrees along the circumferential direction CR of the exhaust portion surface 28A, each of the plurality of protrusions 54 overcomes each of the plurality of first regulating portions 32a. By each of the overcome first regulating portions 32a, the movement of each protrusion 54 in the anti-circumferential direction ACR of the exhaust portion surface 28A is restricted.

[0115] Furthermore, when the person relatively rotates the main body portion 22 and the second ring fastener 50B by, for example, 15 degrees along the circumferential direction CR of the exhaust portion surface 28A, each of the plurality of protrusions 54 slides upward and overcomes each of the plurality of second regulating portions 32b. By each of the overcome second regulating portions 32b, the movement of each protrusion 54 in the anti-circumferential direction ACR of the exhaust portion surface 28A is restricted.

[0116] Furthermore, when a person rotates the main body 22 and the second ring fastener 50B relative to each other by, for example, 15 degrees along the circumferential direction CR of the exhaust portion surface 28A, each of the plurality of protrusions 54 slides upward and overrides each of the plurality of third restricting portions 32c. By each of the overridden third restricting portions 32c, the movement of each protrusion 54 in the anti-circumferential direction ACR of the exhaust portion surface 28A is restricted. The angle by which the main body 22 and the second ring fastener 50B are relatively rotated along the circumferential direction CR of the exhaust portion surface 28A in order for each of the plurality of protrusions 54 to override each of the plurality of third restricting portions 32c is not limited to 15 degrees. For example, it is preferably either 15 degrees or 20 degrees.

[0117] As shown in FIG. 15, each of the plurality of protrusions 54 that has stopped moving in the circumferential direction CR of the exhaust portion surface 28A at the third stage is fixed by being in surface contact and engaging with each of the plurality of third restricting portions 32c. In this case, a fabric having a thickness of X3 (for example, about 0.89 mm) of the fabric constituting the temperature adjustment vest 1 is sandwiched between the surface 25 and the outer flange 51. As a result, as shown in FIG. 15, the body blower 20 is in a state of being attached to the temperature adjustment vest 1. When releasing the attachment of the body blower 20, a person relatively rotates the main body 22 and the second ring fastener 50B by, for example, 45 degrees in the anti-circumferential direction ACR of the exhaust portion surface 28A. Thereby, each of the plurality of protrusions 54 can override each of the first restricting portion 32a and the third restricting portion 32c.

[0118] When each of the plurality of protrusions 54 overrides the third restricting portion 32c, even if a person relatively rotates the main body 22 and the second ring fastener 50B in the circumferential direction CR of the exhaust portion surface 28A, each of the plurality of protrusions 54 cannot override each of the plurality of fourth restricting portions 32d. Thereby, it is possible to prevent the body blower 20 from falling off the temperature adjustment vest 1 due to the relative rotation of the exhaust portion 28 and the second ring fastener 50B in the circumferential direction CR of the exhaust portion surface 28A.

[0119] When attaching the body blower 20 according to the present embodiment to the vest body 2, a person can attach the body blower 20 to the temperature-adjusting vest 1 by attaching two ring fasteners 50 to the outer peripheral wall 27 of the intake part and the outer peripheral wall 29 of the exhaust part with a one-touch operation. Thereby, the attachment of the body blower 20 to the vest body 2 is easier than when attaching a conventional body blower to clothing, and even if the vest body 2 is pulled, the body blower 20 can be prevented from coming off the vest body 2. Further, when the main body part 22 and the first ring fastener 50A, and the main body part 22 and the second ring fastener 50B are relatively rotated, the locations engaged with the respective plurality of protrusions 54 can be changed step by step. Thereby, if the thickness of the fabric of the temperature-adjusting vest 1 is X1, each of the plurality of protrusions 54 engages with each of the plurality of first restricting parts 32a, and the body blower 20 can be attached to the temperature-adjusting vest 1. If the thickness of the fabric of the temperature-adjusting vest 1 is X2, each of the plurality of protrusions 54 engages with each of the plurality of second restricting parts 32b, and the body blower 20 can be attached to the temperature-adjusting vest 1. If the thickness of the fabric of the temperature-adjusting vest 1 is X3, each of the plurality of protrusions 54 engages with each of the plurality of third restricting parts 32c, and the body blower 20 can be attached to the temperature-adjusting vest 1. Therefore, for any thickness of the fabric of the temperature-adjusting vest 1, a person can attach the body blower 20 to the temperature-adjusting vest 1 corresponding to that thickness. Therefore, it becomes easy to attach the body blower 20 according to the present embodiment to the fabric of the temperature-adjusting vest 1, and the usability of the temperature-adjusting vest 1 can be improved. Further, even if the back fabric 3B and the attachment part 10 are sandwiched many times by the surface 25 and the plurality of ring fasteners 50, the back fabric 3B and the attachment part 10 can be made difficult to plastically deform. Therefore, even if the body blower 20 is attached to the temperature-adjusting vest 1, it is possible to prevent rattling or damage to the back fabric 3B and the attachment part 10.

[0120] <Regarding the temperature-adjusted wind FL> FIG. 16 is a sectional view taken along line B-B in FIG. 7, and is a schematic diagram showing the flow of air flowing in the main body of the body blower shown in FIG. 5. As shown in FIGS. 6 and 16, the internal space 22S of the main body 22 is partitioned by a first partition member 61 and a second partition member 62 with the Peltier element 41 of the Peltier element unit 40 as a boundary, and is divided into two spaces in the vertical direction (Y-axis direction in FIG. 17). The first partition member 61 is disposed between the blower fan 45 and the end of the upstream side Fa of the Peltier element unit 40.

[0121] FIG. 17 is a sectional view taken along line A-A in FIG. 6. As shown in FIGS. 6 and 17, the second partition member 62 is disposed between the end of the downstream side Fb of the Peltier element unit 40 and the side end 24b of the second housing portion 24, and the exhaust port 28B and the air supply port 30B are partitioned with the second partition member 62 interposed therebetween.

[0122] That is, in the body blower 20 according to the present embodiment, as shown in FIG. 16, the intake port 26B is a vent for supplying air AR from the outside to the blower fan 45. For example, as shown in FIG. 16, the air AR1 and AR6 whose flow has been changed by contacting the outer peripheral wall 27 of the intake portion are introduced into the internal space 22S from the intake port 26B by the blower fan 45. For example, as shown in FIG. 16, the air AR2 to AR5 whose flow has not been changed without contacting the outer peripheral wall 27 of the intake portion are introduced into the internal space 22S from the intake port 26B by the blower fan 45. Thereafter, the air flow path F by the air AR introduced into the internal space 22S is a flow from the upstream side Fa to the downstream side Fb, and is divided into a flow to the blower side heat sink 42A and a flow to the exhaust side heat sink 42B.

[0123] In the body blower 20 of the present embodiment, by bringing the external air AR into contact with the outer peripheral wall 27 of the intake portion, it becomes easier for the air to flow into the internal space 22S of the main body 22, and it becomes easier to intake a large amount of air AR into the internal space 22S of the main body 22. Thereby, the amount of air flowing through the blower side heat sink 42A and the exhaust side heat sink 42B can be increased, and the temperature adjustment by the body blower 20 can be efficiently performed.

[0124] (1) When the air AR flows through the blower-side heat sink 42A The air AR passes through the blower-side heat sink 42A, undergoes heat exchange with the blower-side heat sink 42A, and becomes the temperature-controlled downstream air FL.

[0125] At this time, when one surface 41a of the Peltier element 41 is the cooling surface, the air AR supplied from the intake port 26B is cooled by undergoing heat exchange with the blower-side heat sink 42A, and becomes the cold air CF as shown in FIG. 6. Therefore, when one surface 41a is the cooling surface, this cold air CF becomes the temperature-controlled downstream air FL.

[0126] Conversely, when one surface 41a of the Peltier element 41 is the heating surface, the air AR supplied from the intake port 26B is heated by undergoing heat exchange with the blower-side heat sink 42A, and becomes the warm air HF as shown in FIG. 6. Therefore, when one surface 41a is the heating surface, this warm air HF becomes the temperature-controlled downstream air FL.

[0127] In the body blower 20 according to the present embodiment, the control unit 21 reverses the direction of the direct current supplied to the Peltier element 41 to switch between the case where the temperature-controlled downstream air FL is the cold air CF and the case where the temperature-controlled downstream air FL is the warm air HF.

[0128] (2) When the air AR flows through the exhaust-side heat sink 42B The air AR passes through the exhaust-side heat sink 42B, undergoes heat exchange with the exhaust-side heat sink 42B, and becomes the exhaust EX, and this exhaust EX is discharged to the outside from the exhaust port 28B.

[0129] In the body blower 20 according to the present embodiment, the entire periphery of the exhaust-side heat sink 42B is covered with the fin cover 44. Therefore, the air AR supplied to the exhaust-side heat sink 42B passes through the gaps between the fins of the exhaust-side heat sink 42B without flowing through the blower-side heat sink 42A and becomes the exhaust EX.

[0130] Also, the air intake side heat sink 42A is also covered entirely by a fin cover 44. Therefore, the air AR supplied to the air intake side heat sink 42A passes through the gaps between the fins of the air intake side heat sink 42A without flowing through the exhaust side heat sink 42B, and becomes the temperature-controlled air FL. Accordingly, the temperature-controlled air FL is generated by completely eliminating mixing with the exhaust EX.

[0131] That is, in the body blower 20 according to the present embodiment, as shown in FIGS. 16 and 19, the exhaust port 28B is an exhaust port for exhausting the exhaust EX that has passed through the gaps between the fins of the exhaust side heat sink 42B to the outside of the main body 22. For example, as shown in FIG. 16, even if the exhaust EX1 whose air flow has changed by contacting the outer peripheral wall 29 of the exhaust part is exhausted from the exhaust port 28B, it does not flow toward the head HD of the wearer HM, but is exhausted to the back of the wearer HM. For example, as shown in FIG. 16, the exhaust EX2 whose air flow has not changed without contacting the outer peripheral wall 29 of the exhaust part is exhausted to the back of the wearer HM. Thereby, it is possible to prevent the exhaust EX flowing out from the exhaust port 28B of the body blower 20 from flowing to the head HD of the wearer HM and the exhaust EX staying in the head HD, which would make the wearer HM uncomfortable.

[0132] The generated temperature-controlled air FL is sent to a blowing area Q provided in the internal space 22S of the main body 22. As shown in FIGS. 18 and 19, the blowing area Q is a space formed between the air outlet 30B and the second partition member 62 and between the second plate portion 24a of the second housing portion 24 and the second partition member 62 with respect to the Y-axis direction. And as shown in FIGS. 18 and 19, the blowing area Q is a space formed in a range between the downstream end Fb of the Peltier element unit 40 and the side end 24b of the second housing portion 24 with respect to the Z-axis direction.

[0133] <Regarding the reflux system 70> Next, the reflux system 70 will be described. FIG. 18 is a plan view showing the inside of the main body of the body blower shown in FIG. 5, and is a schematic diagram showing the flow of the temperature-controlled rear wind. FIG. 19 is a cross-sectional view taken along the line C-C in FIG. 7, and is a schematic diagram showing the flow of the temperature-controlled rear wind and the exhaust inside the main body of the body blower shown in FIG. 5. FIG. 20 is a cross-sectional view taken along the line D-D in FIG. 7, and is a schematic diagram showing the flow of the temperature-controlled rear wind that refluxes toward the blower fan of the body blower shown in FIG. 5.

[0134] As shown in FIGS. 5 to 7 and FIGS. 17 to 20, a reflux system 70 is formed in the body blower 20 according to the present embodiment. The reflux system 70 is a blowing structure provided with a reflux path F1 parallel to the blowing path F2. As shown in FIGS. 16, 18, and 19, the blowing path F2 is a path for directly blowing the temperature-controlled rear wind FL that has passed through the blowing-side heat sink 42A to the outside from the blowing port 30B.

[0135] The reflux path F1 is a path for returning the temperature-controlled rear wind FL that has passed through the blowing-side heat sink 42A to the upstream side Fa of the blowing-side heat sink 42A and supplying the temperature-controlled rear wind FL to the blowing-side heat sink 42A again. As shown in FIGS. 16 and 20, the reflux path F1 merges with the air flow path F by the air AR introduced from the intake port 26B on the upstream side Fa of the blowing-side heat sink 42A.

[0136] Specifically, as shown in FIGS. 5 to 8, FIG. 17, and FIG. 18, the reflux system 70 includes a return flow path 70S, a reflux inlet portion 71, a reflux outlet portion 73, a first return pipe portion 75, a connection portion 76, a second return pipe portion 78, a wind direction adjustment wall 79, and the like. For example, the reflux inlet portion 71 corresponds to the reflux inlet portion according to the present disclosure. For example, the return flow path 70S corresponds to the return flow path according to the present disclosure.

[0137] The wind direction adjustment wall 79 is provided in the blowing region Q. The wind direction adjustment wall 79 corresponds to the wind direction adjustment portion according to the present disclosure. As shown in FIGS. 18 and 19, the wind direction adjustment wall 79 divides the flow of the temperature-controlled rear wind FL into the reflux inlet portion 71 side and the blowing port 30B side.

[0138] Here, as shown in FIGS. 17 and 18, in the air supply region Q, at the branch point 79P of the air direction adjustment wall 79 with respect to the Z-axis direction, the cross-sectional area of the reflux path F1 through which the post-temperature-adjustment air FL flows toward the reflux inlet portion 71 is defined as the first flow path cross-sectional area Sr. Also, the cross-sectional area of the air supply path F2 through which the post-temperature-adjustment air FL flows toward the air supply port 30B is defined as the second flow path cross-sectional area Se.

[0139] Then, when the sum of the first flow path cross-sectional area Sr and the second flow path cross-sectional area Se is the total flow path cross-sectional area S, the ratio k (%) of the first flow path cross-sectional area Sr to the total flow path cross-sectional area S is 0 < k ≦ 50. Preferably, the ratio k (%) is 20 ≦ k ≦ 50, and in this embodiment, the ratio k is approximately 25 (%). If the ratio k exceeds 50 (%), in the air supply region Q, the opening area of the air supply port 30B that blows out the post-temperature-adjustment air FL becomes too small, and the post-temperature-adjustment air FL cannot be supplied from the air supply port 30B with a sufficient air volume.

[0140] The reflux inlet portion 71 and the connection portion 76 are provided on the side portion of the main body portion 22. The reflux outlet portion 73 is provided in the internal space 22S of the main body portion 22. The reflux inlet portion 71 has an inflow side opening 72 formed in the main body portion 22. As shown in FIGS. 18 and 19, the inflow side opening 72 communicates with the air supply region Q. The inflow side opening 72 communicates with the return flow path 70S. For example, the reflux outlet portion 73 corresponds to the reflux outlet portion according to the present disclosure.

[0141] The return flow path 70S is a flow path for refluxing the post-temperature-adjustment air FLr from the reflux inlet portion 71 to the intake introduction portion 48 of the air supply fan 45 disposed upstream Fa of the air supply side heat sink 42A. The return flow path 70S is formed in the section from the reflux inlet portion 71 through the first return pipe portion 75, the connection portion 76, and the second return pipe portion 78 to the reflux outlet portion 73.

[0142] The connection part 76 has a connection part opening 77 formed in the first housing part 23 of the main body part 22. As shown in FIGS. 18 and 20, the connection part opening 77 communicates with the internal space 22S of the main body part 22. As shown in FIG. 18, the connection part opening 77 is disposed at a position on the side part of the first housing part 23, on the upstream side Fa of the air blowing side heat sink 42A, and intersects with an imaginary axis J passing through the rotation center axis O of the air blowing fan 45 along the X-axis direction.

[0143] The space between the reflux inlet part 71 and the connection part 76 is connected by a tubular first return pipe part 75. As shown in FIGS. 5, 6, 18, and 19, the first return pipe part 75 is disposed in a manner along the outer side of the side part of the main body part 22. Further, the connection part 76 is connected to a tubular second return pipe part 78 disposed in the internal space 22S of the main body part 22.

[0144] The second return pipe part 78 is connected to the connection part 76 in a state of communicating with the connection part opening 77 on one side in the X-axis direction (the left side in FIG. 20). The reflux outlet part 73 is formed in a form in which an end part of the second return pipe part 78 on the other side (the right side in FIG. 20) with respect to the X-axis direction is deeply notched from the inner peripheral side to the outer peripheral side with respect to the radial direction of the rotation center axis O of the air blowing fan 46. An outflow side opening 74 is formed at the end part of the second return pipe part 78 in the reflux outlet part 73.

[0145] As shown in FIGS. 6, 16, and 20, the reflux outlet part 73 is provided in a position close to the intake introduction part 48 of the air blowing fan 45 located on the upstream side Fa of the air blowing side heat sink 42A in the internal space 22S of the main body part 22. That is, the reflux outlet part 73 is an outlet for returning the temperature-adjusted air FLr refluxed to the reflux flow path 70S to the upstream side Fa of the air blowing side heat sink 42A, and is disposed at a position where it can be sucked by the air blowing fan 45. Therefore, the refluxed temperature-adjusted air FLr easily flows from the outflow side opening 74 of the reflux outlet part 73 to the intake introduction part 48 of the air blowing fan 45.

[0146] As the blades 46 of the blower fan 45 rotate, the temperature-adjusted rearward flow air FLr that flows into the recirculation path F1 and recirculates is sucked toward the recirculation outlet portion 73 through the return flow path 70S and blown from the outflow side opening 74 to the intake introduction portion 48 of the blower fan 45. As a result, at the intake introduction portion 48 of the blower fan 45, the recirculated temperature-adjusted rearward flow air FLr merges with the air AR newly introduced from the intake port 26B and is supplied again to the blower-side heat sink 42A.

[0147] <Verification experiment> Next, for the purpose of confirming the significance of the body blower 20 according to the present embodiment, an experiment was conducted to verify the effect of the recirculation system 70. In the experiment, the body blower according to the example and the body blowers according to Comparative Examples 1 to 3 were used.

[0148] In the experiment, for each of the body blower according to the example and the body blowers according to Comparative Examples 1 to 3, the temperature of the blown air from the air outlet was measured over time with a thermometer, and the behavior of the temperature change in which the blown air becomes cold air was confirmed for each body blower.

[0149] The body blower according to the example is the body blower 20 according to the present embodiment. The body blower according to Comparative Example 1 is Product A. The body blower according to Comparative Example 2 is Product B. The body blower according to Comparative Example 3 is Product C.

[0150] (1) Experimental method In the experiment, in the laboratory under the same ambient temperature, the body blowers according to the example and Comparative Examples 1 to 3 were used simultaneously. Also, in the experiment, the four body blowers according to the example and Comparative Examples 1 to 3 were arranged at positions sufficiently separated from each other so as not to affect each other with respect to the temperature of the blown cold air.

[0151] In the experiment, in both the example and Comparative Examples 1 to 3, the body blower continued to blow cold air from the air outlet for 30 minutes under the ambient temperature in the laboratory. The temperature of the cold air was measured every minute with a thermometer.

[0152] (2) Experimental conditions <Common conditions for the examples and Comparative Examples 1 to 3> · Temperature characteristics of the Peltier element; having a temperature range of approximately 10 to 15°C in comparison with the external ambient temperature · Heat sink on the heat absorption side in contact with the heat absorption surface of the Peltier element; air supply side heat sink 42A (Example) and heat sinks having performance comparable to that of the air supply side heat sink 42A (Comparative Examples 1 to 3) · Heat sink on the heat generation side in contact with the heat generation surface of the Peltier element; exhaust side heat sink 42B (Example) and heat sinks having performance comparable to that of the exhaust side heat sink 42B (Comparative Examples 1 to 3) · Air supply fan; a sirocco fan with the same air volume · Air intake port; an opening formed in the same manner as the air intake port 26B · Exhaust port; an opening formed in the same manner as the exhaust port 28B

[0154] (3) Experimental results Figure 21 is a diagram showing in a table the relationship between the ambient temperature and the cold air temperature measured every hour in a verification experiment in which cold air was continuously supplied for 30 minutes by the body air supply devices according to the example and Comparative Examples 1 to 3.

[0155] Figure 22 is a diagram showing in a table the temperature difference per unit time that changed between the measured value of the cold air temperature at a previous time and the measured value at a subsequent time in the verification experiment by the body air supply devices according to the example and Comparative Examples 1 to 3.

[0156] The temperature of the cold air was measured every minute with a thermometer. However, in FIGS. 21 to 22, the results of the cold air temperature measured after 5 minutes from the start of the air blowing are described in a manner of recording every 5 minutes.

[0157] The results of the verification experiment are as shown in FIGS. 21 to 22. As shown in FIG. 21, the ambient temperature T in the laboratory was 35°C at the start of the experiment, but it became 36.4°C at the end of the experiment, rising by 1.4°C during the 30 minutes of the verification experiment.

[0158] In the case of the body air blower according to the embodiment, as shown in FIG. 21, the temperature Ta of the cold air was 33.7°C at 1 minute after the start of the experiment, 31°C at 2 minutes after the start of the experiment, 28.8°C at 3 minutes after the start of the experiment, and 24.8°C at the end of the experiment. Also, as shown in FIG. 21, the temperature difference (Ta - T) between the temperature Ta of the cold air and the ambient temperature T was -1.6°C at 1 minute after the start of the experiment, -4.2°C at 2 minutes after the start of the experiment, -6.6°C at 3 minutes after the start of the experiment, and -12.1°C at the end of the experiment.

[0159] On the other hand, in the case of the body air blower according to Comparative Example 1, as shown in FIG. 21, the temperature Tb of the cold air was 34°C at 1 minute after the start of the experiment, 32.6°C at 2 minutes after the start of the experiment, 31.8°C at 3 minutes after the start of the experiment, and 25.7°C at the end of the experiment. Also, as shown in FIG. 21, the temperature difference (Tb - T) between the temperature Tb of the cold air and the ambient temperature T was -1.3°C at 1 minute after the start of the experiment, -2.6°C at 2 minutes after the start of the experiment, -3.6°C at 3 minutes after the start of the experiment, and -10.7°C at the end of the experiment.

[0160] In the case of the body air blower according to Comparative Example 2, as shown in FIG. 21, the temperature Tc of the cold air was 34.3°C at 1 minute after the start of the experiment, 33.5°C at 2 minutes after the start of the experiment, 32°C at 3 minutes after the start of the experiment, and 27.8°C at the end of the experiment. Also, as shown in FIG. 21, the temperature difference (Tc - T) between the temperature Tc of the cold air and the ambient temperature T was -1°C at 1 minute after the start of the experiment, -1.7°C at 2 minutes after the start of the experiment, -3.4°C at 3 minutes after the start of the experiment, and -8.6°C at the end of the experiment.

[0161] In the case of the body blower according to Comparative Example 3, as shown in FIG. 21, the temperature Td of the cold air was 34.1 °C at 1 minute after the start of the experiment, 33.4 °C at 2 minutes after the start of the experiment, and 33.2 °C at 3 minutes after the start of the experiment. At the end of the experiment, it was 27.4 °C. Also, as shown in FIG. 21, the temperature difference (Td - T) between the temperature Td of the cold air and the ambient temperature T was -1.2 °C at 1 minute after the start of the experiment, -1.8 °C at 2 minutes after the start of the experiment, and -2.2 °C at 3 minutes after the start of the experiment. At the end of the experiment, it was -9 °C.

[0162] <Discussion> Discuss the results of the verification experiment. From the results of the verification experiment, in the body blower according to the embodiment, as the first event, at the end of the experiment, the temperature Ta of the blown cold air has a temperature difference of 1.7 to 3.5 °C from the temperatures Tb, Tc, and Td of the cold air by the body blowers according to Comparative Examples 1 to 3, and it can be seen that it is the lowest.

[0163] Also, as shown in FIG. 22, the present applicant confirmed the temperature difference per unit time that changed between the measured value measured at an earlier time and the measured value measured at a later time for the temperature of the cold air blown by the body blowers according to the embodiment and Comparative Examples 1 to 3. From the results of the verification experiment, for such a temperature difference per unit time, there was no particularly large difference between the embodiment and Comparative Examples 1 to 3 during the 25 minutes from the time when 5 minutes had elapsed since the start of the experiment to the end of the experiment.

[0164] However, as shown in FIG. 22, from the start of the experiment until especially until 3 minutes have elapsed, in the case of the body blower according to Comparative Example 1, the temperature difference per unit time (Tb2 - Tb1) remains at around 1 °C. Also, in the case of the body blower according to Comparative Example 2, the temperature difference per unit time (Tc2 - Tc1) remains at around 1 °C. In the body blower according to Comparative Example 3, the temperature difference per unit time (Td2 - Td1) is only around 0.5 °C.

[0165] On the other hand, in the case of the body blower according to the embodiment, as the second event, the temperature difference per hour (Ta2 - Ta1) is nearly 2 to 3 °C. From this, it can be seen that in the body blower according to the embodiment, the cooling rate of the cold air blown out immediately after the start of blowing is the largest, especially as compared with the body blowers according to Comparative Examples 1 to 3.

[0166] On the other hand, in the case of the body blower according to Comparative Example 1, the time required after starting the blowing of the cold air, as the time until the temperature difference (Tb - T) between the ambient temperature T and the cold air temperature Tb reaches nearly -9 °C in one example, was 15 to 20 minutes.

[0167] Also, in the case of the body blower according to Comparative Example 2, the time required after starting the blowing of the cold air, as the time until the temperature difference (Tc - T) between the ambient temperature T and the cold air temperature Tc reaches nearly -9 °C in one example, was 30 minutes, which was the time when the experiment ended.

[0168] Similarly, in the case of the body blower according to Comparative Example 3, the time required after starting the blowing of the cold air, as the time until the temperature difference (Td - T) between the ambient temperature T and the cold air temperature Td reaches nearly -9 °C in one example, was 30 minutes, which was the time when the experiment ended.

[0169] On the other hand, in the case of the body blower according to the embodiment, the time required after starting the blowing of the cold air, as the time until the temperature difference (Ta - T) between the ambient temperature T and the cold air temperature Ta reaches nearly -9 °C as described above in one example, was only about 5 minutes.

[0170] In the case of the embodiment, such a required time corresponded to 1 / 4 to 1 / 3 compared to the case of Comparative Example 1, and corresponded to 1 / 6 in comparison with the cases of Comparative Examples 2 and 3. From this also, it can be seen that in the body blower according to the embodiment, as the third event, the cooling rate of the cold air blown out immediately after the start of blowing is 3 to 6 times larger than that of the body blowers according to Comparative Examples 1 to 3.

[0171] In the body blower according to the embodiment, the reason why the aforementioned first event, second event, and third event were confirmed is presumably because the body blower according to the embodiment is the body blower 20 that constitutes the reflux system 70.

[0172] That is, in the body blower 20, as shown in FIG. 16, the air AR introduced from the intake port 26B by the blower fan 45 flows through the air flow path F in the internal space 22S of the main body 22 in a state where the flow velocity is further increased. After that, when the air AR passes through the blower-side heat sink 42A, the temperature-adjusted air FL is blown out from the air outlet 30B with a larger air volume. In the body blower 20 attached to the temperature-adjusting vest 1, the temperature-adjusted air FL directed toward the wearer HM is blown out toward the body with a large air volume. As a result, the comfort of the wearer HM is improved, especially for people who require cold air, such as outdoors in extremely hot weather, or for people who are exposed to cold winds outdoors and feel cold and require warm air.

[0173] However, if the flow velocity of the air AR introduced from the intake port 26B becomes too large, the air AR flowing through the air flow path F cannot sufficiently exchange heat with the blower-side heat sink 42A. Therefore, if the state where sufficient heat exchange cannot be performed continues, a heat exchange incomplete event of blowing out from the air outlet 30B may also occur.

[0174] Therefore, as one means to avoid the occurrence of such a heat exchange incomplete event, in order to increase the passing time of the introduced air with respect to the blower-side heat sink and sufficiently perform heat exchange with the blower-side heat sink, increasing the size of the Peltier element unit is considered. Also, suppressing the air volume of the temperature-adjusted air blown out from the air outlet is considered. However, in a blower device in which the size of the Peltier element unit is increased or the air volume of the temperature-adjusted air is suppressed, not only does the device become larger and more expensive, but it is also not user-friendly for the user.

[0175] On the other hand, since the body blower 20 is provided with the reflux system 70, it is possible to suppress incomplete heat exchange events without increasing the size of the Peltier element unit or reducing the air volume of the temperature-controlled air flow.

[0176] That is, the air AR introduced from the intake port 26B into the internal space 22S of the main body 22 may flow through the air flow path F at a greater flow velocity and may not be sufficiently heat-exchanged by the blower-side heat sink 42A. However, the body blower 20 has the reflux system 70. Therefore, even in such a case, as shown in FIG. 18, when the temperature-controlled air flow FL that has not been sufficiently heat-exchanged reaches the blowing area Q, it returns to the blower-side heat sink 42A again through the reflux path F1 and becomes the refluxed temperature-controlled air flow FLr.

[0177] Since the refluxed temperature-controlled air flow FLr can be heat-exchanged again with the blower-side heat sink 42A, it is easier to be adjusted to a temperature state closer to the desired temperature. Therefore, it is considered that the body blower 20 configured with the reflux system 70 can adjust the temperature-controlled air flow FL blown out to the outside from the air outlet 30B to a temperature closer to the desired temperature in a shorter time, especially when the temperature difference from the ambient temperature T is large immediately after the start of blowing.

[0178] <Air flow in the temperature adjustment vest 1> Next, with reference to FIG. 23, the air flow in the temperature adjustment vest 1 will be described. FIG. 23 is an explanatory diagram for explaining the air flow sent out by the body blower attached to the temperature adjustment vest shown in FIG. 1.

[0179] As shown in FIG. 23, part of the air AR introduced from the intake port 26B into the internal space 22S of the main body 22 flows through the air flow path F in the internal space 22S of the main body 22 by the blower fan 45. Then, when part of the air AR passes through the blower-side heat sink 42A, the temperature-adjusted air FL, FLr is blown out from the air outlet 30B with a larger air volume. In the body blower device 20 attached to the temperature-adjustment vest 1, the temperature-adjusted air FL, FLr directed toward the wearer HM is blown out toward the back and the neck of the wearer HM with a large air volume. When the temperature-adjusted air FL, FLr blown onto the back of the wearer HM flows from the collar part 6 to the neck muscle NP of the wearer HM, the comfort of the wearer HM is improved, especially for those who require cold air, such as outdoors in extremely hot weather, or those who feel cold when exposed to cold wind outdoors and require warm air. Further, the temperature-adjusted air FL, FLr flowing toward the neck muscle NP of the wearer HM may flow toward the head HD of the wearer HM after passing through the neck muscle NP. Thereby, the comfort of the wearer HM is improved by the temperature-adjusted air FL, FLr flowing toward the head HD, especially for those who require cold air, such as outdoors in extremely hot weather, or those who feel cold when exposed to cold wind outdoors and require warm air.

[0180] On the other hand, as shown in FIG. 23, when part of the air AR introduced from the intake port 26B into the internal space 22S of the main body 22 passes through the exhaust-side heat sink 42B by the blower fan 45, it becomes the exhaust EX after heat exchange with the exhaust-side heat sink 42B. This exhaust EX is discharged to the outside from the exhaust port 28B. Thereby, it is possible to prevent the exhaust EX from flowing toward the wearer HM of the temperature-adjustment vest 1 and staying in the head HD of the wearer HM.

[0181] Next, the clothing attachment structure of the body blower device 20 according to the present embodiment and the actions and effects of the temperature-adjustment vest 1 with the body blower device 20 will be described.

[0182] The clothing attachment structure of the body air blower 20 of the present embodiment includes a main body 22 in which an air outlet 30B is formed, a Peltier element 41 disposed in the internal space 22S of the main body 22, a heat sink unit 42 having a blowing-side heat sink 42A, and a blowing fan 45 that blows air to the blowing-side heat sink 42A formed on one surface 41a of the Peltier element 41. The body air blower 20 sends out temperature-adjusted air, which is either cold air or warm air that has passed from the upstream side to the downstream side, from the air outlet 30B into the vest body 2. An insertion hole 11 is formed in the back fabric 3B of the temperature-adjusting vest 1 for detachably attaching the body air blower 20. The main body 22 has a surface 25 on the opposite side of one surface 41a of the Peltier element 41, on which an intake portion 26 and an exhaust portion 28 are formed. The body air blower 20 is provided with a plurality of ring fasteners 50 that can be attached from the surface 25 side. Each ring fastener 50 has a protrusion 54 that can be connected to the intake portion 26 and the exhaust portion 28, and a sandwiching surface 52 for sandwiching the surface 25 and the back fabric 3B. The intake portion 26 and the exhaust portion 28 each have a fixing rail 31 that can be connected to the protrusion 54. The attachment of the body air blower 20 to the back fabric 3B of the temperature-adjusting vest 1 is performed by connecting the protrusion 54 of the first ring fastener 50A to the fixing rail 31 of the intake portion 26 and connecting the protrusion 54 of the second ring fastener 50B to the fixing rail 31 of the exhaust portion 28 while sandwiching the back fabric 3B between the surface 25 and the sandwiching surface 52.

[0183] According to the clothing attachment structure of the body air blower 20 of the present embodiment, when attaching the body air blower 20 to the back clothing fabric 3B, with the back clothing fabric 3B sandwiched between the front surface 25 and the sandwiching surface 52, the protrusion 54 of the first ring fastener 50A is connected to the fixing rail 31 of the intake part 26. Further, the protrusion 54 of the second ring fastener 50B is connected to the fixing rail 31 of the exhaust part 28. Thereby, for example, a person can easily attach the body air blower 20 to the back clothing fabric 3B of the temperature adjustment vest 1. Further, for example, even if the temperature adjustment vest 1 is pulled during work, since it is attached in a state where the back clothing fabric 3B of the temperature adjustment vest 1 is sandwiched between the front surface 25 and the sandwiching surface 52, it is difficult for the body air blower 20 to come off from the temperature adjustment vest 1. Therefore, for example, even if an unexpected situation occurs during work, the temperature-adjusted air FL is sent into the vest main body 2 from the air outlet 30B of the body air blower 20 attached to the back clothing fabric 3B of the temperature adjustment vest 1, and the temperature of the wearer HM can be adjusted. Therefore, it is possible to facilitate the attachment of the body air blower 20 to the back clothing fabric 3B of the temperature adjustment vest 1 and prevent the body air blower 20 from coming off from the back clothing fabric 3B of the temperature adjustment vest 1 due to an unexpected situation.

[0184] In the clothing attachment structure of the body air blower 20 of the present embodiment, the intake part 26 is an intake part in which an intake port 26B for sucking air into the internal space 22S of the main body part 22 is formed, and the exhaust part 28 is an exhaust part in which an exhaust port 28B for exhausting air to the outside of the main body part 22 is formed.

[0185] According to the clothing attachment structure of the body air blower 20 of the present embodiment, air is sucked from the intake part 26 of the body air blower 20 attached to the back clothing fabric 3B into the internal space 22S of the main body part 22, and the air is exhausted from the exhaust part 28 of the body air blower 20 to the outside of the main body part 22. Thereby, while each role of the intake part 26 and the exhaust part 28 is fulfilled, for example, even if an unexpected situation occurs during work, it is possible to prevent the body air blower 20 from coming off from the back clothing fabric 3B of the temperature adjustment vest 1.

[0186] In the clothing attachment structure of the body air blower 20 of the present embodiment, in the intake section 26, an intake section outer peripheral wall 27 is formed which is perpendicular to the surface 25 with respect to a center line AX1 passing through the center of the intake section surface 26A on the inner side of the peripheral wall forming the intake section 26. In the exhaust section 28, an exhaust section outer peripheral wall 29 is formed which is perpendicular to the surface 25 with respect to a center line AX2 passing through the center of the exhaust section surface 28A on the inner side of the peripheral wall forming the exhaust section 28. Fixed rails 31 are respectively formed on the outer peripheral surfaces 27A of the intake section outer peripheral wall 27 and the outer peripheral surfaces 29A of the exhaust section outer peripheral wall 29. Protrusions 54 are respectively formed on the inner peripheral surfaces 53 of a plurality of ring fasteners 50, which is preferable.

[0187] According to the clothing attachment structure of the body air blower 20 of the present embodiment, the back fabric 3B is sandwiched between the surface 25 and the sandwiching surface 52, and the fixed rail 31 on the outer peripheral surface 27A of the intake section outer peripheral wall 27 is connected to the protrusion 54 on the inner peripheral surface 53 of the first ring fastener 50A. Further, the fixed rail 31 on the outer peripheral surface 29A of the exhaust section outer peripheral wall 29 is connected to the protrusion 54 on the inner peripheral surface 53 of the second ring fastener 50B. Thereby, not only can the body air blower 20 be attached to the temperature adjustment vest 1 by the intake section outer peripheral wall 27, but also a part of the external air AR is brought into contact with the outer peripheral surface 27A to change the air flow, making it easier to be introduced from the intake port 26B into the internal space 22S. Further, not only can the body air blower 20 be attached to the temperature adjustment vest 1 by the exhaust section outer peripheral wall 29, but also a part of the exhaust EX in the internal space 22S is brought into contact with the outer peripheral surface 29A to change the air flow, preventing it from flowing to the head HD of the wearer HM. Therefore, the amount of air flowing into the outside of the main body 22 can be increased to improve the efficiency of temperature adjustment by the temperature-adjusted wind FL, and the exhaust EX can be prevented from staying in the head HD so that the wearer HM does not feel uncomfortable.

[0188] In the clothing attachment structure of the body air blower 20 of the present embodiment, in the internal space 22S of the main body 22, a blowing region Q of the temperature-adjusted wind FL is provided between the downstream side Fb of the heat sink unit 42 and the air outlet 30B. In the blowing region Q, a reflux inlet portion 71 communicating with a return flow path 70S capable of refluxing the temperature-adjusted wind FL to the upstream side Fa of the blowing-side heat sink 42A is formed.

[0189] According to the clothing attachment structure of the body blower 20 of the present embodiment, the temperature-controlled air FL after temperature adjustment can be returned from the reflux inlet 71, passed through the return flow path 70S, refluxed to the upstream side Fa of the blower-side heat sink 42A, and supplied to the blower-side heat sink 42A again. As a result, the temperature-controlled air FL including the refluxed temperature-controlled air FLr comes out from the air outlet 30B. That is, in some cases, the temperature-controlled air FL that has once passed through the blower-side heat sink 42A may be in a state where sufficient heat exchange cannot be performed between the air AR flowing through the air flow path F and the blower-side heat sink 42A. Even in such a case, the temperature-controlled air FL in this state passes through the blower-side heat sink 42A again, so that heat exchange can be performed with the blower-side heat sink 42A, and thus the temperature can be adjusted to a temperature closer to the desired temperature. In particular, it is also assumed that the body blower 20 is used in an environment where the ambient temperature surrounding the body blower 20 and the temperature of the temperature-controlled air FL to be blown are significantly different, for example, by a temperature difference of more than ten degrees Celsius. In this case, due to the reflux system 70, the temperature-controlled air FL blown out from the air outlet 30B can be adjusted to the desired temperature, for example, with a temperature change rate 3 to 5 times or more that of a conventional body blower without a return flow path, and can be blown with good responsiveness in terms of temperature adjustment from the start of blowing. Also, when the user is working or the like while being exposed to the scorching sun on a sweltering day when the outside air temperature exceeds 35°C, for example, the user strongly tends to demand that they can immediately cool their body with cold air at a comfortable temperature. Even in such a case, the body blower 20 can immediately blow cold air CF (temperature-controlled air FL) cooled to the desired temperature with good responsiveness onto the user's body, and quickly cool the body of the user who is feeling uncomfortable due to the heat and sweat. Therefore, when blowing the temperature-controlled air FL generated through heat exchange between the air AR introduced from the intake port 26B and the blower-side heat sink 42A, the temperature-controlled air FL can be adjusted to a comfortable temperature state for the wearer HM in a shorter time from the start of blowing and then blown.

[0190] In the clothing attachment structure of the body blower 20 of the present embodiment, in the internal space 22S of the main body 22, a reflux outlet 73 that connects to a second return pipe 78 communicating with the return flow path 70S is formed on the upstream side Fa of the blower-side heat sink 42A. At the reflux outlet 73, the inhaled air AR (wind) and the temperature-adjusted and refluxed air FLr merge.

[0191] According to the clothing attachment structure of the body blower 20 of the present embodiment, the temperature-adjusted and refluxed air FLr is refluxed to the upstream side Fa of the blower-side heat sink 42A on the air flow path F. Subsequently, the refluxed temperature-adjusted and refluxed air FLr can be sent to the blower-side heat sink 42A again by the air flow caused by the newly introduced air AR from the intake port 26B. Therefore, there is no need for a sending means for sending the refluxed temperature-adjusted and refluxed air FLr toward the blower-side heat sink 42A, and the refluxed temperature-adjusted and refluxed air FLr can pass through the blower-side heat sink 42A by the flow of the newly introduced air AR. As a result, for example, the temperature inside the vest body 2 of the wearer HM in an environment with a large deviation, such as a temperature difference of more than ten degrees Celsius, can be adjusted earlier.

[0192] In the clothing attachment structure of the body blower 20 of the present embodiment, in the blowing area Q, a wind direction adjustment wall 79 that divides the flow of the temperature-adjusted air FL into the return inlet 71 side and the air outlet 30B side is provided.

[0193] According to the clothing attachment structure of the body blower 20 of the present embodiment, the temperature-adjusted air FL that reaches the blowing area Q can be reliably separated into a return path F1 leading to the return inlet 71 and a blowing path F2 leading to the air outlet 30B. Therefore, the temperature-adjusted air FL that flows into the return path F1 becomes the temperature-adjusted and refluxed air FLr through the return flow path 70S and is returned to the upstream side Fa of the blower-side heat sink 42A. In addition, the temperature-adjusted air FL that flows into the blowing path F2 is blown out to the outside from the air outlet 30B. In this way, since the wind direction adjustment wall 79 can appropriately adjust the flow of the temperature-adjusted air FL and FLr, for example, the temperature inside the vest body 2 of the wearer HM in an environment with a large deviation, such as a temperature difference of more than ten degrees Celsius, can be appropriately adjusted.

[0194] In the clothing attachment structure of the body air blower 20 of the present embodiment, at the branch point 79P of the wind direction adjustment wall 79, when the flow path cross-sectional area of the temperature-adjusted air FL flowing on the reflux inlet 71 side is the first flow path cross-sectional area Sr, the flow path cross-sectional area of the temperature-adjusted air FL flowing on the air outlet 30B side is the second flow path cross-sectional area Se, and the sum of the first flow path cross-sectional area Sr and the second flow path cross-sectional area Se is the total flow path cross-sectional area S, the ratio k (%) of the first flow path cross-sectional area Sr to the total flow path cross-sectional area S is 0 < k ≤ 50.

[0195] According to the clothing attachment structure of the body air blower 20 of the present embodiment, the body air blower 20 can ensure that the air volume of the temperature-adjusted air FL blown out from the air outlet 30B is not significantly reduced and has no adverse effect on the user. In addition, the body air blower 20 can also adjust the temperature of the blown temperature-adjusted air FL to a temperature close to the desired temperature in a shorter time from the start of the air blowing. Therefore, in the body air blower 20, the flow rate and the temperature are harmoniously balanced, and the temperature-adjusted air FL can be blown out from the air outlet 30B. On the other hand, in the body air blower 20, as the value of the ratio k (%) increases, the air volume of the temperature-adjusted air FL blown out from the air outlet 30B decreases. On the one hand, when the value of the ratio k (%) increases, the temperature-adjusted air FL blown out from the air outlet 30B mainly becomes the temperature-adjusted air FLr refluxed through the reflux path F1 and is blown out. Therefore, although the temperature-adjusted air FL has a large air volume and is not blown out from the air outlet 30B, in the temperature-adjusted air FL blown out from the air outlet 30B, the rate of temperature change towards the desired temperature also tends to increase as the value of the ratio k (%) increases after the start of the air blowing. Therefore, as long as the value of the ratio k (%)) is not limited to the range of 0 < k ≤ 50 and becomes larger, the time required for the temperature-adjusted air FL blown out from the air outlet 30B to reach the desired temperature is shortened. Thereby, with the temperature-adjusted air FL in which the flow rate and the temperature of the temperature-adjusted air FL are harmoniously balanced, for example, in an environment where there is a large deviation with a temperature difference of more than ten degrees Celsius, the inside of the vest body 2 of the wearer HM can be appropriately temperature-adjusted.

[0196] The clothing attachment structure of the body blower 20 according to this embodiment is such that an exhaust port 28B is formed in the main body 22, the heat sink unit 42 has an exhaust-side heat sink 42B formed on the other surface 41b opposite to one surface 41a of the Peltier element 41, and the blower fan 45 sends air AR as wind to the exhaust-side heat sink 42B together with the air-supply-side heat sink 42A.

[0197] According to the clothing attachment structure of the body air blower 20 of the present embodiment, in the Peltier element 41, it is possible to suppress the deterioration of the cooling efficiency and the heat generation efficiency over time on one surface 41a and the other surface 41b. As a result, the temperature-adjusted air FL can be continuously blown out at a stable temperature. That is, the Peltier element 41 has the characteristic of presenting low-temperature heat on the heat-absorbing side heat transfer surface and high-temperature heat on the heat-generating side heat transfer surface due to the heat transfer occurring between the heat-absorbing side and the heat-generating side on both heat transfer surfaces of one surface 41a and the other surface 41b. In this Peltier element 41, if the heat generated particularly on the heat-generating side is not efficiently exhausted to the outside, it becomes difficult for heat absorption to occur gradually on the heat-absorbing side heat transfer surface. When the Peltier element 41 reaches such a state, not only does the cooling efficiency on the heat transfer surface of the Peltier element decrease over time, but there is also a risk of causing damage or burnout to the Peltier element, which is not preferable. On the other hand, in the body air blower 20 according to the present embodiment, the blower fan 45 sends the air AR as wind to the exhaust side heat sink 42B together with the blower side heat sink 42A. Particularly, when one surface 41a is under heat absorption, the high-temperature exhaust heat generated on the other surface 41b is heat-exchanged with the air AR sent from the blower fan 45 at the exhaust side heat sink 42B, which is the heat transfer destination, to become warm air HF, and this warm air HF is exhausted to the outside from the exhaust port 28B. Therefore, the Peltier element 41 can continuously maintain the Peltier effect without suffering from the adverse effects caused by insufficient heat dissipation of the exhaust heat on the other surface 41b with respect to the heat transfer between the heat-absorbing side and the heat-generating side on both heat transfer surfaces of one surface 41a and the other surface 41b. Therefore, damage to the Peltier element 41 caused by the inability to continuously dissipate the exhaust heat generated on the other surface 41b of the Peltier element 41 can be suppressed. As a result, for example, in an environment where there is a large deviation with a temperature difference of more than ten degrees Celsius, the inside of the vest body 2 of the wearer HM can be stably temperature-adjusted by the temperature-adjusted air FL.

[0198] The temperature-adjusting vest 1 of the present embodiment has a body air blower 20 that forms a clothing attachment structure of the body air blower 20, and is detachable from the vest body 2.

[0199] According to the temperature-adjusting vest 1 of the present embodiment, the attachment of the body blower 20 to the temperature-adjusting vest 1 adopting the clothing attachment structure of the body blower 20 of the present embodiment is easy, and it is possible to prevent the body blower 20 from detaching from the vest body 2 in the event of an unexpected situation.

[0200] As described above, the present disclosure has been described in accordance with the embodiments. However, the present disclosure is not limited to the above embodiments, and can be appropriately modified and applied without departing from the gist thereof. Of course, the configurations according to the above embodiments and the following modification examples may be appropriately combined. The technical features of the above embodiments and the following modification examples can be appropriately deleted if they are not described as essential in this specification.

[0201] In the above embodiment, the number of ring fasteners 50 that can be attached to the main body 22 of the body blower 20 was two, but the present invention is not limited to this. For example, the number of ring fasteners 50 that can be attached to the main body 22 of the body blower 20 may be three or more. If there are three or more locations on the main body 22 where the ring fastener 50 can be attached, the body blower 20 attached to the temperature-adjusting vest 1 can be made more difficult to detach. However, it is preferable that the number of ring fasteners 50 and the number of locations on the main body 22 of the body blower 20 where the ring fastener 50 can be attached are the same. This is because if the number of ring fasteners 50 is more than the number of locations where the ring fastener 50 can be attached, it will become an obstacle.

[0202] In the main body 22 of the above-described embodiment, there were two openings to which the ring fastener 50 could be attached, namely the intake part 26 and the exhaust part 28. However, it is not limited to this. The number of openings in the main body 22 to which the ring fastener 50 can be attached may be three or more. If there are two or more openings in the main body 22 to which the ring fastener 50 can be attached, the body blower 20 attached to the temperature adjustment vest 1 can be made more difficult to come off. However, it is preferable that the number of openings in the main body 22 of the body blower 20 to which the ring fastener 50 can be attached is the same as the number of ring fasteners 50. This is because if the number of openings is more than the number of ring fasteners 50, it will be obstructive.

[0203] In the above-described embodiment, the body blower 20 was attached to the temperature adjustment vest 1 by attaching the ring fasteners 50 to the intake part 26 and the exhaust part 28 respectively. However, it is not limited to this. For example, two intake parts 26 may be provided on the first plate part 23a, and the body blower 20 may be attached to the temperature adjustment vest 1 by attaching the ring fasteners 50 to the two intake parts 26 respectively. In this case, a larger amount of air can be taken into the internal space 22S of the main body 22 by the two intake parts 26. In addition, for example, two exhaust parts 28 may be provided on the first plate part 23a, and the body blower 20 may be attached to the temperature adjustment vest 1 by attaching the ring fasteners 50 to the two exhaust parts 28 respectively. In this case, a larger amount of exhaust can be exhausted to the outside of the main body 22 by the two exhaust parts 28.

[0204] In the above-described embodiment, each of the restricting portions 32 on the outer peripheral surface 27A of the outer peripheral wall 27 of the intake portion engages with each of the plurality of protrusions 54 of the first ring fastener 50A, and the body blower 20 is attached to the temperature-adjusting vest 1. However, the present invention is not limited to this. For example, a male screw of the first ring fastener 50A may be screwed into a female screw on the outer peripheral surface 27A of the outer peripheral wall 27 of the intake portion, and the body blower 20 may be attached to the temperature-adjusting vest 1. In addition, for example, a convex portion of the first ring fastener 50A may be fitted into a concave portion on the outer peripheral surface 27A of the outer peripheral wall 27 of the intake portion, and the body blower 20 may be attached to the temperature-adjusting vest 1.

[0205] In the above-described embodiment, each of the restricting portions 32 on the outer peripheral surface 29A of the outer peripheral wall 29 of the exhaust portion engages with each of the plurality of protrusions 54 of the second ring fastener 50B, and the body blower 20 is attached to the temperature-adjusting vest 1. However, the present invention is not limited to this. For example, a male screw of the second ring fastener 50B may be screwed into a female screw on the outer peripheral surface 29A of the outer peripheral wall 29 of the exhaust portion, and the body blower 20 may be attached to the temperature-adjusting vest 1. In addition, for example, a female screw of the second ring fastener 50B may be screwed into a male screw on the outer peripheral surface 29A of the outer peripheral wall 29 of the exhaust portion, and the body blower 20 may be attached to the temperature-adjusting vest 1. For example, a convex portion of the second ring fastener 50B may be fitted into a concave portion on the outer peripheral surface 29A of the outer peripheral wall 29 of the exhaust portion, and the body blower 20 may be attached to the temperature-adjusting vest 1. In addition, for example, a concave portion of the second ring fastener 50B may be fitted into a convex portion on the outer peripheral surface 29A of the outer peripheral wall 29 of the exhaust portion, and the body blower 20 may be attached to the temperature-adjusting vest 1.

[0206] In the above-described embodiment, each of the restricting portions 32 on the outer peripheral surface 27A of the outer peripheral wall 27 of the intake portion engages with each of the plurality of protrusions 54 of the first ring fastener 50A, and the body blower 20 is attached to the temperature-adjusting vest 1. However, the present invention is not limited to this. For example, each of the restricting portions 32 on the inner peripheral surface of the outer peripheral wall 27 of the intake portion may engage with each of the plurality of protrusions on the outer peripheral surface of the first ring fastener 50A, and the body blower 20 may be attached to the temperature-adjusting vest 1. Thereby, since it is possible to make it difficult for the first ring fastener 50A to be contacted from the outside, the body blower 20 can be made more difficult to be removed from the vest body 2.

[0207] In the above-described embodiment, each of the restricting portions 32 on the outer peripheral surface 29A of the outer peripheral wall 29 of the exhaust portion engages with each of the plurality of protrusions 54 of the second ring fastener 50B, and the body blower 20 is attached to the temperature-adjusting vest 1. However, the present invention is not limited to this. For example, each of the restricting portions 32 on the inner peripheral surface of the outer peripheral wall 29 of the exhaust portion may engage with each of the plurality of protrusions on the outer peripheral surface of the second ring fastener 50B, and the body blower 20 may be attached to the temperature-adjusting vest 1. Thereby, since it is possible to make it difficult for the second ring fastener 50B to be contacted from the outside, the body blower 20 can be made more difficult to be removed from the vest body 2.

[0208] In the above-described embodiment, an example in which the body blower 20 is attached to the vest body 2 so that the air outlet 30B faces the collar portion 6 side has been described. However, the present invention is not limited to this. For example, the body blower 20 may be attached to the vest body 2 so that the air outlet 30B faces the opposite side of the collar portion 6, that is, the waist of the wearer HM. Thereby, the upper body of the wearer HM can be temperature-adjusted by the temperature-adjusted air FL sent out from the air outlet 30B.

[0209] In the above-described embodiment, the number of body blowers 20 attached to the vest body 2 may be two or more, and the present invention is not limited to the embodiment, and various changes are possible.

[0210] In the above-described embodiment, the vest body 2 having the attachment portions 10 provided at a total of two locations on the back fabric 3B of the clothing fabric 3 was given as an example. However, the present invention is not limited to this. The number, arrangement positions, and arrangement methods of the attachment portions 10 provided on the clothing fabric 3 can be appropriately changed according to the use of the clothing (product) with the body air blower according to the present disclosure, the physical build of the wearer, etc., that is, according to the specifications of the product.

[0211] For example, in the embodiment, the blower fan 45 was a sirocco fan capable of sucking the air AR toward the blades 46 by the rotation of the blades 46. However, the blower fan may be, in addition to the sirocco fan, for example, an axial flow fan such as a propeller fan or a turbo fan. However, since the axial flow fan does not have the ability to suck air toward the blades by the rotation of the blades, it is necessary to configure a suction means for drawing the temperature-adjusted return air to be recirculated from the recirculation inlet portion to the upstream side of the first fins in the return flow path of the body air blower according to the present disclosure.

[0212] In the present embodiment, as shown in FIG. 8, the blower portion 30 was formed from the second plate portion 24a of the second housing portion 24 to the side end 24b of the second housing portion 24, and the air outlet 30B was formed in the blower portion 30. However, it is not necessary to be limited to this. For example, the air outlet may be arranged only on the second plate portion 24a side of the second housing portion 24. For example, the air outlet may be arranged at the side end of the main body portion at a position parallel to the cross section of the air flow path passing through the first fins, such as when arranged only on the side end 24b side of the second housing portion 24.

[0213] In the present embodiment, as shown in FIG. 10, the blower side heat sinks 42A and the exhaust side heat sinks 42B that are vertically erected from the flat plate portions 42Aa and 42Ba with innumerable fins formed by being folded back in a substantially wave shape and having gaps between adjacent fins were given as an example. However, the configurations of the first fins and the second fins are not limited to the embodiment, and may be configured in a manner capable of exchanging heat with the outside air and dissipating the heat generated by the Peltier element, and can be variously changed.

[0214] In this embodiment, the body blower 20 having the outer shape shown in FIGS. 5 to 9 is taken as an example. However, the outer shape of the body blower is not limited to the embodiment and can be changed as appropriate.

[0215] In the body blower 20 according to this embodiment, the air outlet 30B may be configured to be detachably attached with a blower control tool that controls the flow of the temperature-adjusted air FL to be blown out. With such a blower control tool, the body blower according to the present disclosure can blow the temperature-adjusted air from the air outlet of the attached blower control tool in a desired direction.

[0216] In the above embodiment, the number of the protrusions 54 was 4. However, it is not limited to this. For example, the number of the protrusions 54 may be 3 or less, or may be 5 or more. However, the number of the protrusions 54 is preferably the same as the number of the fixed rails 31. This is because if the number of the protrusions 54 and the number of the fixed rails 31 are different, it becomes difficult to attach the body blower 20 to the temperature adjustment vest 1.

[0217] In the above embodiment, the number of the fixed rails 31 was 4. However, it is not limited to this. For example, the number of the fixed rails 31 may be 3 or less, or may be 5 or more. However, the number of the fixed rails 31 is preferably the same as the number of the protrusions 54. This is because if the number of the protrusions 54 and the number of the fixed rails 31 are different, it becomes difficult to attach the body blower 20 to the temperature adjustment vest 1.

[0218] In the above embodiment, the number of the restricting portions 32 provided on each of the plurality of sliding surfaces 33 was 4. However, it is not limited to this. For example, the number of the restricting portions 32 provided on each of the plurality of sliding surfaces 33 may be 3 or less, or may be 5 or more.

[0219] In the above embodiment, the number of the gaps 34 was 4. However, it is not limited to this. For example, the number of the gaps 34 may be 3 or less, or may be 5 or more.

[0220] All of the plurality of fixed rails 31 in the above embodiment have an inclination angle θ1 of 3° between one end 31a and the other end 31b on the sliding surface 33. However, it is not limited thereto. For example, for all of the plurality of fixed rails, the inclination angle θ1 between one end and the other end on the sliding surface 33 may be less than 3° or may exceed 3°. However, when the inclination angle θ1 is less than 1°, the height difference between one end and the other end of the fixed rail disappears, so it cannot correspond to the thicknesses of various fabrics, which is not preferable. On the other hand, when the inclination angle θ1 is 10° or more, it becomes difficult to sandwich the fabric of the temperature adjustment vest 1 and attach it to the temperature adjustment vest 1, which is not preferable.

[0221] In the above embodiment, with the surface 25 and the ring fastener 50 sandwiching the back fabric 3B and the outer peripheral edge portion 12, each of the plurality of protrusions 54 engages with each of the restricting portions 32, and the body blower 20 is attached to the temperature adjustment vest 1. However, due to the weight of the body blower 20, the back fabric 3B and the outer peripheral edge portion 12 sandwiched by the surface 25 and the ring fastener 50 may bend. Therefore, measures may be taken on the back fabric 3B and the outer peripheral edge portion 12 to prevent the back fabric 3B and the outer peripheral edge portion 12 sandwiched by the surface 25 and the ring fastener 50 from bending due to the weight of the body blower 20.

Industrial Applicability

[0222] As is clear from the above description, the body blower facilitates attachment to the fabric forming the clothing and prevents the body blower from coming off the fabric forming the clothing due to unforeseen circumstances. Therefore, it has industrial applicability.
