Description

[Technical field]

[0001] The present disclosure relates to an airflow control device that is attached to the air outlet of a body airflow device worn on the body and controls the flow of temperature-adjusted air blown out from the air outlet. It also relates to a body airflow device and a body airflow device with an airflow control device that includes such an airflow control device. [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 a lack of air conditioning equipment or insufficient cooling, workers who work outdoors in extreme heat, workers who work in humid indoor environments, and people who enjoy recreation, sports, or watching events under the blazing sun are unable to cool down with air conditioning.

[0004] In response to these circumstances, clothing with air conditioning functions and portable air conditioners have become increasingly popular in recent years, mainly for people seeking to escape the heat. Among these air conditioners, air blowers using Peltier elements have also been developed. Examples of such air blowers are disclosed in Patent Documents 1 and 2.

[0005] Patent Document 1 discloses a clothing cooling device comprising a housing, a Peltier element within the housing, a cooling fin formed on one side of the Peltier element, a heat dissipation fin formed on the other side opposite the one side, a blower fan that blows air to the cooling fins and the heat dissipation fins, an air intake for taking air into the housing, a cold air outlet for blowing out cold air that has passed through the cooling fins, and a heat dissipation outlet for exhausting hot air that has passed through the heat dissipation fins.

[0006] The housing has an air intake, a cold air outlet, and a heat release outlet formed in opposite directions. In Patent Document 1, the clothing cooling device is attached to the user's clothing by arranging and fixing a flange on the cold air outlet to the inner and outer circumferential surfaces of an opening in the clothing.

[0007] Patent Document 2 discloses an air blowing unit that is attached and fixed to the belt of a user's trousers and blows temperature-adjusted air to the user's back. Patent Document 2 includes a Peltier element that adjusts the temperature of the air blown from the fan, a casing that houses the fan and the Peltier element, and an air intake nozzle. The air intake nozzle is attached to an air intake port formed in the casing.

[0008] In Patent Document 2, the air intake nozzle is cylindrical and bent in a roughly Z-shape so that the temperature-adjusted air is not blown directly onto the user's back from the air intake port. This is said to prevent the user's back from being overcooled or overheated by the temperature-adjusted air. [Prior art documents] [Patent documents]

[0009] [Patent Document 1] Patent No. 7290237 [Patent Document 2] JP 2023-93944 A Summary of the Invention [Problem to be solved by the invention]

[0010] However, Patent Documents 1 and 2 have the following problems.

[0011] In Patent Document 1, the clothing cooling device is attached to the clothing with a cold air port fixed to the opening of the clothing. At this time, the cold air port faces the user's body. Therefore, the cold air blown out from the cold air port hits the user's body directly. Therefore, only the parts of the user's body that are directly exposed to the cold air are cooled by the cold air, and other parts are not exposed to the cold air at all.

[0012] Therefore, the clothing cooling device cannot cool a wider area of ​​the user's body with the cold air blown out from the cold air port. In addition, the clothing cooling device may overcool the part of the user's body exposed to the spot with the cold air blown out from the cold air port.

[0013] Meanwhile, in dangerous work sites, such as civil engineering sites and factory plant facilities, workers generally wear heavy work clothes and helmets to protect themselves from danger. When such work sites are exposed to the scorching sun and are subject to humid weather conditions, workers working at the site become stuffy around the neck and above the head inside the helmet because there is almost no ventilation. As a result, the workers feel uncomfortable due to this stuffiness.

[0014] Such an event occurs frequently. Therefore, workers are looking for a blower that can supply cool air to the sweaty parts while wearing work clothes and a helmet. In particular, in the above-mentioned work sites, many workers are looking for a single blower that can be used for general purposes so that it can supply cool air to the sweaty parts in a manner that matches the position of the sweaty parts, even if the sweaty parts are in different positions on the body, such as around the neck or on the top of the head inside the helmet.

[0015] In Patent Document 2, a blower unit is attached to the belt of the user's trousers, and temperature-adjusted air can only be blown to the spinal area of ​​the back from an air intake nozzle attached to the air intake port. Therefore, Patent Document 2 has a problem in that it is not possible to generally blow temperature-adjusted air to each part of the body to be blown, such as when blowing air to the top of the head inside a helmet, with a single blower unit.

[0016] The present disclosure has been made to solve the above-mentioned problems, and aims to provide an air-blowing control device, an air-blowing device for the body, and an air-blowing device for the body with an air-blowing control device attached, which is easy for the user to use and can efficiently blow temperature-adjusted air supplied from the air-blowing device to the part of the body to which air is to be blown. [Means for solving the problem]

[0017] (1) In order to solve the above problems, one aspect of the present disclosure is an air supply control device, which is a housing having an outer housing part in which an air intake port and an exhaust port are formed, and an inner housing part connected to the outer housing part by butting against each other in an opposing arrangement, and in which an air supply port is arranged, a Peltier element arranged within the housing, a cooling fin formed on one side of the Peltier element, a heat dissipation fin formed on the other side opposite to the one side, and an air supply fan that introduces air from the air intake port and sends it to the cooling fins and the heat dissipation fins, and is intended for a body air supply device that is worn on the body and blows out temperature-adjusted air, which is either cold air that has passed through the cooling fins or hot air that has passed through the heat dissipation fins, from the air supply port. The air supply control device is attached to the body air supply device to control the flow of the temperature-conditioned air, and is characterized in that it comprises a hollow circulation path through which the temperature-conditioned air can flow, a connection part formed to be detachable from the air supply outlet by at least one fixing means of fitting, fastening, and engagement, an introduction part that takes the temperature-conditioned air supplied from the air supply outlet into the circulation path from an inlet when the connection part is attached to the housing, and a blowing part that extends from the introduction part to an outlet of the circulation path, and in the outlet side circulation path that passes through the blowing part, the cross-sectional area of ​​the outlet side of the circulation path is the same size as or smaller than that of the introduction part side.

[0018] According to this aspect, the temperature-adjusted air generated by the body air blowing device can be efficiently blown over a wide area along the body surface toward the desired part of the user's body by the air blowing control device.

[0019] (2) In the aspect described in (1) above, it is preferable that the outlet side circulation path has a cross section on the outlet side smaller than that on the inlet side, and the blowing section is formed in a shape narrower on the outlet side than on the inlet side.

[0020] According to this aspect, since the airflow control device has a shape that narrows on the outlet side, the blowing section can be easily positioned in a narrow space, such as the narrow space between the user's body and the clothing being worn, or the narrow space between the head of a user wearing a helmet and the shell of the helmet.

[0021] (3) In the aspect described in (1) or (2) above, it is preferable that a flow guide section is formed in the flow path of the inlet section to guide the flow of the temperature-adjusted air taken in toward the outlet section.

[0022] According to this aspect, when the temperature-adjusted air taken in by the inlet section flows along the inner wall of the circulation path to the outlet section, the generation of excessive turbulence in the circulating temperature-adjusted air due to a decrease in flow rate or pressure loss can be suppressed.

[0023] (4) In any one of the aspects described in (1) to (3) above, it is preferable that the connection part is made of a flexible material, and that the air supply control device can be connected to the body air supply device by elastically deforming the connection part and attaching it to the air supply port.

[0024] According to this aspect, when connecting and disconnecting the airflow control device and the airflow control tool, the airflow control device and the airflow device for the body can both be constructed with simple structures, so that they can be manufactured at low cost. Moreover, the user can easily connect and disconnect the airflow control device and the airflow control tool for the body.

[0025] In particular, if the connection part is made of a relatively flexible elastic material such as silicone rubber, the airtightness at the joint between the airflow control tool and the body air blower is improved, so that the temperature-adjusted air supplied from the body air blower can be sent to the introduction part of the airflow control tool without leaking from the joint.

[0026] (5) In any one of the aspects described in (1) to (4) above, it is preferable that, when connecting to the body blower device, a fixing portion is formed in the blower port to fix the connection portion.

[0027] According to this aspect, the body air blowing device can be connected to and disconnected from the air blowing control device at the fixing part, making it possible to use it in cases where the air blowing control device is needed and cases where it is not needed.

[0028] In addition, when the airflow control device is connected to the body air blower at the fastening portion by a fastening means such as a screw, the airflow control device can be firmly connected to the body air blower. Therefore, even if a large external force or impact acts on the connected airflow control device and body air blower during use, the airflow control device is prevented from coming off the body air blower due to such external force or impact.

[0029] (6) In any one of the aspects (1) to (5) above, it is preferable to provide a flap that changes the direction of the temperature-adjusted airflow flowing through the airflow path.

[0030] According to this aspect, even when the user has positioned the outlet of the blowing section toward the desired part of the body to which the temperature-regulated air is to be directed, by opening the flap, additional temperature-regulated air can be sent to another part of the body to which the user simultaneously wishes to receive the temperature-regulated air.

[0031] (7) In any one of the aspects described in (1) to (6) above, in the first air flow control device including at least two blowing sections, it is preferable that each of the blowing sections is formed in a manner in which it branches and bends in different directions at the introduction section as a boundary, and that the two blowing sections are arranged directly opposite each other in one direction, or are arranged in an approximately V-shape.

[0032] According to this aspect, the airflow control device can deliver the temperature-adjusted air over a wider area to the parts of the user's body that the user wishes to receive the temperature-adjusted airflow. Moreover, the temperature-adjusted airflow spreads over a wider area from both the one air outlet and the other air outlet and is delivered along the surface of the user's body without hitting the user's body directly, so the user can feel comfortable.

[0033] (8) In any one of the aspects described in (1) to (6) above, in the second air flow control device including one blowing section, it is preferable that the blowing section is formed in a manner such that it is bent in a substantially J-shape in one direction with the introduction section as a boundary.

[0034] According to this aspect, the outlet of the blowing section can be positioned so as not to face the user's body, so that the temperature-adjusted air supplied from the body blowing device can be blown locally along the surface of the body toward the part of the user's body that wishes to receive the air, without hitting the user's body directly.

[0035] (9) In any one of the aspects described in (1) to (8) above, it is preferable that the blowing section has a wall member surrounding the circulation path and a protrusion protruding from the wall member, and that when the connection section is attached to the body blower, the protrusion is formed in a portion of the wall member that faces the inner housing portion of the body blower.

[0036] According to this aspect, the protrusion functions as a rib for reinforcing the wall member, so that the blowing section can be configured with higher rigidity.

[0037] (10) In addition, a body blower with an air supply control device in another aspect of the present disclosure made to solve the above problems comprises a housing having an outer casing portion having an intake port and an exhaust port, and an inner casing portion connected to the outer casing portion in an opposing arrangement by butting against the outer casing portion, and having an air supply port arranged therein, a Peltier element arranged within the housing, a cooling fin formed on one side of the Peltier element, a heat dissipation fin formed on the other side opposite the one side, and an air supply fan that introduces air from the intake port and sends it to the cooling fins and the heat dissipation fins, and is intended for a body blower that is worn on the body and blows out from the air supply port either cold air that has passed through the cooling fins or hot air that has passed through the heat dissipation fins, and is characterized in that the air supply control device of any one of the aspects described in (1) to (9) above is detachably connected to the air supply port of the body blower.

[0038] According to this aspect, the temperature-adjusted air is blown by the airflow control device along the body surface without hitting the user directly, so that the user can feel comfortable. In addition, the airflow control device can efficiently blow air along the body surface over a wide area toward the part of the user's body that desires to receive the temperature-adjusted air.

[0039] (11) Also, a body air blower in another aspect of the present disclosure made to solve the above problems includes a housing having an outer housing part having an air intake port and an exhaust port formed therein, and an inner housing part connected to the outer housing part by butting against each other in an opposing arrangement, a Peltier element disposed within the housing, a cooling fin formed on one side of the Peltier element, a heat dissipation fin formed on the other side opposite the one side, and an air blower fan that introduces air from the air intake port and blows it to the cooling fins and the heat dissipation fins, and when the body is worn, temperature-adjusted air, which is either cold air that has passed through the cooling fins or hot air that has passed through the heat dissipation fins, The air blowing device for the body, which blows air from an air blowing area, is equipped with an air direction changing member in which an opening portion formed in a manner that allows the temperature-conditioned air to flow to the outside and a blocking portion that blocks the flow of the temperature-conditioned air to the outside are arranged in different directions from each other, the housing forming the cover of the air blowing device includes an enclosing gap where a part of the space including the air blowing area is opened, the enclosing gap is provided at a connection point between a first side portion of the housing and a second side portion adjacent to the first side portion in a different direction from the first side portion, and the air direction changing member forms part of the housing and is attached to the enclosing gap.

[0040] According to this aspect, the airflow direction changing member of the body blower allows the user to freely select the direction of the temperature-adjusted air to be blown according to the user's purpose. Therefore, when the user uses the body blower that he or she owns, the range of options for the installation mode of the body blower is wider, and the degree of freedom in the mode of use of the body blower is high.

[0041] (12) In addition, a body air blower with an air blowing control device according to another aspect of the present disclosure made to solve the above problems includes a housing including an outer housing part having an air intake port and an air exhaust port formed therein, and an inner housing part connected to the outer housing part by butting against the outer housing part in an opposing arrangement, a Peltier element disposed within the housing, a cooling fin formed on one side of the Peltier element, a heat dissipation fin formed on the other side opposite the one side, and an air blower fan that introduces air from the air intake port and blows air to the cooling fins and the heat dissipation fins, and is a body air blower that is worn on the body and blows out temperature-adjusted air, which is either cold air that has passed through the cooling fins or hot air that has passed through the heat dissipation fins, from a blowing area, and the temperature-adjusted air flows to the outside. The air direction changing member has an opening formed in a manner that allows air to pass through, and a blocking portion that blocks the flow of the temperature-regulated air to the outside, and the opening is arranged in different directions from the blocking portion, and the housing that forms the cover of the body blower includes an enclosing gap that leaves a part of the space including the air blowing area open, and the enclosing gap is provided at a connection point between a first side portion of the housing and a second side portion adjacent to the first side portion in a direction different from that of the first side portion, and the air direction changing member forms part of the housing, and for a body blower attached to the enclosing gap, an air blowing control device of any one of the aspects described in (1) to (9) above is removably attached to the opening of the air direction changing member.

[0042] According to this aspect, since the device body of the body blower with airflow control device is configured to include an airflow direction changing member, the airflow direction changing member can be used to freely select the direction of the temperature-adjusted air to be blown according to the user's purpose. Therefore, when a user uses the body blower with airflow control device that he or she owns, the range of options for the installation mode is wider, and the degree of freedom in the mode of use of the body blower with airflow control device is high.

[0043] Therefore, a user can use the body air blower with air blowing control device in a variety of ways, such as by placing it in a clothing pocket, attaching it to the belt of work trousers, or attaching it to light clothing while jogging.

[0044] (13) In the aspect described in (11) or (12) above, it is preferable that the air direction changing member is formed in such a manner that it can be reversibly attached to the surrounding missing portion in either arrangement form, that is, a first arrangement form in which the opening is arranged on the first side side and the blocking portion is arranged on the second side side, and a second arrangement form in which the opening is arranged on the second side side and the blocking portion is arranged on the first side side.

[0045] According to this aspect, the body air blower with airflow control device can change the direction of the opening that blows out the temperature-conditioned air according to the position of the part of the user's body that wishes to receive the temperature-conditioned air.

[0046] (14) In any one of the aspects described in (10) to (13) above, it is preferable that the inner casing portion includes a fixed portion formed so as to be engageable with a fixing portion of the air blowing control device, the housing is constructed so that the inner casing portion and the outer casing portion are each separately constructed, and the fixing portion of the air blowing control device and the fixed portion of the inner casing portion are engaged with each other to connect the air blowing port of the body blowing device, which forms the main body of the body blowing device with air blowing control device, to the connection portion of the air blowing control device.

[0047] According to this aspect, in the body air blower with an air blower control device, an air blower selected as required from a plurality of types of air blower can be attached to the air outlet of the body air blower.

[0048] (15) In any one of the aspects described in (11) to (13) above, it is preferable that the opening of the air direction changing member is formed in a manner that allows it to be attached and detached to the connection portion of the air flow control device.

[0049] According to this aspect, the user can select between the first and second arrangements for the arrangement of the air direction changing member relative to the surrounding gap each time he or she uses the body air blower with air blowing control device he or she owns, depending on the purpose of use, and therefore the direction of the temperature-adjusted air to be blown can be easily changed.

[0050] (16) In the aspect described in any one of (10) to (15) above, it is preferable that the protective cover is provided with a shell attachment portion that can be attached to the shell of a helmet.

[0051] According to this aspect, the user can attach the body air blower with the air blowing control device integrally with the helmet.

[0052] (17) In the aspect described in (15) above, it is preferable that the inner casing portion is a first inner casing including a fixing portion formed so as to be detachable from the cap body mounting portion, and the housing is composed of the outer casing portion and the first inner casing portion.

[0053] According to this aspect, the air blower for body with the airflow control device can be used when not attached to a helmet and when attached to a helmet. When the air blower for body with the airflow control device is attached to a helmet, the temperature-adjusted air is, for example, mainly cool air.

[0054] When a user wears a helmet equipped with a body air blower with airflow control device that blows out cool air, the body air blower with airflow control device can blow temperature-regulated air over the head of the user wearing the helmet and around the user in the space inside the helmet, thereby providing comfort to the user wearing the helmet.

[0055] (18) In any one of the above aspects (10) to (15), it is preferable that the device has a clothing attachment part that can be attached to clothing.

[0056] According to this embodiment, the user can attach the body air blower with the air blowing control device integrally with the clothing to be worn.

[0057] (19) In the aspect described in (17) above, it is preferable that the clothing attachment portion is a gap formed between the body air blower device, which constitutes the main body of the body air blower device with air blowing control device, and the air blowing control device.

[0058] According to this aspect, the user can attach and wear the body air blower with air blowing control device to the clothing by simply inserting, for example, the collar of the clothing to be worn, as well as the placket, cuffs, collar, and lower edges of the front and back body of a shirt, into the clothing attachment portion. Effect of the Invention

[0059] Therefore, the air flow control device, body air blower, and body air blower with air flow control device disclosed herein are easy to use for the user, and have the excellent effect of efficiently blowing temperature-adjusted air supplied from the body air blower to the part of the body to which air is desired.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0061] Hereinafter, an airflow control device, a personal airflow device, and a personal airflow device with an airflow control device according to the present disclosure will be described in detail with reference to first to twelfth embodiments.

[0062] The airflow control device according to the present disclosure is an attachment to be attached to the air outlet of a body air blower described below. The body air blower with airflow control device according to the present disclosure is configured by adding the airflow control device according to the present disclosure to the body air blower that constitutes the main body.

[0063] The body blower and the body blower with a blower controller according to the present disclosure are used by people who particularly require cool air, such as workers who work outdoors wearing helmets in extremely hot weather, workers who work in work clothes in humid indoor environments, people who engage in recreation, sports, or watching games under the blazing sun, etc. Alternatively, the body blower is used by people who particularly require warm air, such as workers whose hands become cold after doing wet work in winter, or people who are exposed to cold winds and engaged in activities outdoors while feeling cold.

[0064] <Embodiment 1> [1. Overview of the body air blower] First, an outline of the body air blower to which the air blowing control device according to the present disclosure is attached will be briefly described with reference to Figures 1 to 7. The air blowing control device according to the present disclosure is attached to a body air blower having a basic configuration including the main parts of the body air blower 2A configured as shown in Figures 1 to 5.

[0065] Fig. 1 is a perspective view showing a main part of a body blower as an example of an attachment of an air blowing control tool according to embodiment 1. Fig. 2 is an exploded perspective view of a main part of the body blower shown in Fig. 1. Fig. 3 is a plan view of the body blower shown in Fig. 1 as viewed from the outer casing side. Fig. 4 is a perspective view of the body blower shown in Fig. 1 as viewed from the inner casing side, and Fig. 5 shows a plan view as viewed from the inner casing side. Fig. 6 is a side view of the body blower shown in Fig. 1.

[0066] In the body blower shown in Fig. 1, the direction from upper right to lower left is defined as the X-axis direction, the direction from lower right to upper left is defined as the Y-axis direction, and the up-down direction is defined as the Z-axis direction, and the directions defined in Fig. 1 are also used in Fig. 2 and the subsequent figures. Also, power sources for Peltier element 31 and blower fan 35 are not shown in each figure.

[0067] As shown in FIGS. 1 to 7, the body blower 2A(2) includes a housing 10, a Peltier element unit 30, a blower fan 35, a control unit 38, and the like.

[0068] Two Peltier element units 30 are arranged inside the housing 10. The Peltier element unit 30 has a Peltier element 31, a heat sink 32, and a fin cover 34. The Peltier element 31 is a type of plate-shaped semiconductor thermoelectric element having one surface 31a and another surface 31b on the opposite side. The Peltier element 31 is electrically connected to a control unit 38 and a power source (not shown) via a power supply port 39.

[0069] When a direct current is supplied to the Peltier element 31 from a power source, one surface 31a absorbs heat and becomes an absorbing state (cooling surface) due to the Peltier effect, while the other surface 31b generates heat and becomes a heating state (heating surface). When the direction of the supplied direct current is reversed by the control unit 38, in the Peltier element 31, the other surface 31b absorbs heat and becomes an absorbing state (cooling surface), while the one surface 31a generates heat and becomes a heating state (heating surface). In other words, when the control unit 38 reverses the direction of the direct current supplied to the Peltier element 31, the cooling surface and the heating surface are switched between the one surface 31a and the other surface 31b.

[0070] The Peltier element 31 has the characteristic of absorbing heat and generating heat at a temperature that has a relative temperature difference from the outside air temperature, for example, in a temperature range of about 20 to 50° C. That is, for example, when the Peltier element 31 absorbs and generates heat in summer when the outside air temperature is 35° C., the cooling surface exhibits heat of 15 to -15° C., which becomes cold heat for cooling the body. At the same time, the heating surface exhibits heat of 55 to 85° C., which becomes exhaust heat.

[0071] On the other hand, when the Peltier element 31 absorbs and generates heat in winter when the outside temperature is 5°C, the cooling surface exhibits heat of -15 to -45°C, which becomes exhaust heat, and at the same time, the heating surface exhibits heat of 25 to 55°C, which becomes heat for warming the body.

[0072] In this embodiment, the Peltier element 31 has a temperature characteristic of absorbing heat and generating heat at the same time in a temperature range of about 20 to 50° C. relative to the outside air temperature, as an example.

[0073] However, the Peltier element is not limited to the temperature characteristics given in this embodiment, and may be configured with appropriate changes as long as the temperature characteristics can cool the body to a degree that does not cause frostbite and warm the body to a degree that does not cause burns by the temperature-adjusted air FL described later. As an example, the temperature characteristics of the Peltier element are a temperature range of about 10 to 40°C or about 10 to 20°C relative to the outside air temperature.

[0074] Fig. 7 is an explanatory diagram showing a Peltier unit configured in the body blower shown in Fig. 1. As shown in Fig. 2 and Fig. 7, the heat sink 32 is composed of a blower-side heat sink 32A and an exhaust-side heat sink 32B, and the blower-side heat sink 32A and the exhaust-side heat sink 32B form a pair. The blower-side heat sink 32A corresponds to either the cooling fin according to the present disclosure or the heat dissipation fin according to the present disclosure, and the exhaust-side heat sink 32B corresponds to either the heat dissipation fin according to the present disclosure or the cooling fin according to the present disclosure.

[0075] The blower-side heat sink 32A is formed to a size that allows it to come into contact with one surface 31a of the Peltier element 31 over almost the entire area, and has numerous fins folded back in a generally corrugated shape, standing vertically from a flat plate portion 32Aa with gaps between adjacent fins. The exhaust-side heat sink 32B is formed to a size that allows it to come into contact with the other surface 31b of the Peltier element 31 over almost the entire area, and has numerous fins folded back in a generally corrugated shape, standing vertically from a flat plate portion 32Ba with gaps between adjacent fins.

[0076] 7, in the Peltier element unit 30, a surface of a flat plate portion 32Aa of the air-supply side heat sink 32A and one surface 31a of the Peltier element 31 are disposed opposite each other so as to be in surface contact with each other. In addition, a surface of a flat plate portion 32Ba of the exhaust side heat sink 32B and the other surface 31b of the Peltier element 31 are disposed opposite each other so as to be in surface contact with each other.

[0077] However, strictly speaking, due to a difference in accuracy between the surface shape of the flat plate portion 32Aa of the air-supply side heat sink 32A and the surface shape of one surface 31a of the Peltier element 31, there is a small gap (gap) between the surface of the flat plate portion 32Aa and the one surface 31a. Similarly, due to a difference in accuracy between the surface shape of the flat plate portion 32Ba of the exhaust side heat sink 32B and the surface shape of the other surface 31b of the Peltier element 31, there is a small gap (gap) between the surface of the flat plate portion 32Ba and the other surface 31b.

[0078] Therefore, between the Peltier element 31 and the blower-side heat sink 32A, and between the Peltier element 31 and the exhaust-side heat sink 32B, there is a grease layer 33 that fills the gaps with grease. The grease has relatively high thermal conductivity, for example, a thermal conductivity of at least 5 W / m·K, and maintains relatively high viscosity within a temperature range from 0 degrees to approximately 100°C. By providing the grease layer 33, the heat generated by the Peltier element 31 is transferred to the heat sink 32 on the one surface 31a and the other surface 31b with reduced heat transfer loss.

[0079] The body blower 2A(2) according to the first embodiment has two Peltier element units 30 arranged side by side. However, the number of Peltier element units each having a Peltier element, a cooling fin, and a heat dissipation fin is not limited to two, and may be variously changed, for example, to one, three or more.

[0080] The body blower 2A(2) according to the first embodiment has two Peltier element units 30 arranged side by side, and each of the two Peltier elements has heat absorption and heat generation properties. On the other hand, the Peltier element unit can be configured with one large Peltier element, with the heat absorption and heat generation properties being approximately the same as those of two small Peltier elements.

[0081] However, when comparing the first condition using one large Peltier element with the second condition using two small Peltier elements, the second condition may be superior to the first condition in terms of response of the heat absorption and heat generation behavior generated by the Peltier element. Therefore, the body blower 2A etc. according to the present embodiment 1 has two Peltier element units 30 arranged side by side.

[0082] As shown in FIG. 7, the Peltier element unit 30 is configured such that the fin cover 34 surrounds the entire air-supply side heat sink 32A and the exhaust side heat sink 32B that are in contact with the Peltier element 31.

[0083] 2, the blower fan 35 is provided in the internal space 10S of the housing 10 in accordance with the position of the intake port 21. In this embodiment, the blower fan 35 is a multi-blade blower (sirocco fan), which is a type of centrifugal blower. Note that the blower fan may be, for example, a propeller fan (axial flow), a turbo fan, etc., other than the sirocco fan.

[0084] A sirocco fan is a roughly cylindrical blower with multiple blades arranged in a ring shape around the central axis O of rotation, and it blows air (wind) sucked in along the central axis outward from between the rotating blades. Unlike axial fans such as propeller fans and turbo fans, sirocco fans are less susceptible to disturbances caused by wind direction and strength on the air they suck in, and they blow air using centrifugal force acting on the air they suck in, so they make little noise when in operation.

[0085] On the other hand, since a sirocco fan uses centrifugal force acting on the sucked air by rotating multiple blades to blow air, the wind force of the sirocco fan is generally smaller than that of an axial flow fan such as a propeller fan or a turbo fan. Therefore, in the internal space 10S of the body blower 2A etc. according to the present embodiment 1, the housing 10 is provided with a width-reducing passage 15 between the blower fan 35 and the Peltier element unit 30.

[0086] In the width-reducing passage 15, the air flow path width K2 is narrower than the air flow path width K1 passing through the center of rotation of the blower fan 35 so that the wind force due to the blowing pressure, flow velocity, etc. of the air blown by the blower fan 35, i.e., the temperature-adjusted air FL described later, is greater.

[0087] The ratio of the flow path width K2 to the flow path width K1 is preferably within a range of 25% or more and 75% or less, for example, because this allows the wind force sent by the blower fan 35 to be increased and the air sent by the blower fan 35 to be evenly sent to the two Peltier element units 30 in a well-balanced manner.

[0088] The housing 10 has an outer housing part 11 and an inner housing part 12A(2) which are separate bodies. The outer housing part 11 and the inner housing part 12A are butted against each other in an opposing arrangement and joined together to form an integrated body in a generally flat plate shape having an internal space 10S. The outer shape of the housing 10 is such that the outer peripheries of one side (upper side in the vertical direction in FIG. 1) of two long sides along the X-axis direction are connected to each other in an arc shape, and the outer peripheries of the other side (lower side in the vertical direction in FIG. 1) of these two long sides are connected to each other by a linear short side along the Y-axis direction.

[0089] An internal space 10S is defined between the outer housing portion 11 and the inner housing portion 12A. An air intake port 21 and an air exhaust port 22 are formed in the outer housing portion 11 and spaced apart from each other in the X-axis direction. An air blow port 23 is formed in the inner housing portion 12A closer to the air exhaust port 22 in the X-axis direction. As shown in Figs. 2 and 5, an airflow direction adjusting wall 24 is formed in the internal space 10S of the housing 10 adjacent to the air exhaust port 22 and the air blow port 23.

[0090] Fig. 8 is a cross-sectional view taken along the line AA in Fig. 3, and is a schematic diagram showing the flow of air in the internal space of the body blower shown in Fig. 1. As shown in Figs. 1 to 3, the housing 10 has an air intake 21 that opens a part of the flat surface 11a of the outer casing 11. The air intake 21 serves as a vent for supplying air AR introduced from the outside to the blower fan 35, as shown in Fig. 8.

[0091] 1 to 3, the housing 10 has an exhaust port 22 that opens in a part of the flat surface 11a of the outer case portion 11. As shown in Fig. 8, the exhaust port 22 discharges the air AR introduced into the internal space 10S from the intake port 21 and the exhaust air EX that has passed through the exhaust-side heat sink 32B to the outside.

[0092] The exhaust-side heat sink 32B is covered with a fin cover 34. Therefore, in the exhaust-side heat sink 32B, when the air AR supplied from the blower fan 35 passes through the gaps between the fins, the exhaust air EX is not diffused toward the blower-side heat sink 32A, etc., but is discharged from the exhaust port 22 along the airflow direction adjustment wall 24 through the gaps between the fins in the exhaust-side heat sink 32B.

[0093] 4 to 6, the housing 10 has an air outlet 23 that is opened in a part of the flat surface 12a of the inner housing portion 12A. As shown in Fig. 8, the air outlet 23 blows out the temperature-adjusted air FL, which is air AR introduced into the internal space 10S from the air intake 21 and has passed through the air-blowing-side heat sink 32A, to the outside in a flow that follows the air direction adjusting wall 24.

[0094] In the Peltier element 31, when one surface 31a is a cooling surface, the air AR supplied from the air intake 21 is cooled with heat exchange with the air-blowing heat sink 32A, and becomes cold air CF as shown in Fig. 8. Therefore, when one surface 31a is a cooling surface, this cold air CF becomes temperature-adjusted air FL.

[0095] In contrast, when one surface 31a of the Peltier element 31 is the heating surface, the air AR supplied from the air intake 21 is heated through heat exchange with the air-blowing heat sink 32A, and becomes hot air HF as shown in Fig. 8. Therefore, when the one surface 31a is the heating surface, this hot air HF becomes temperature-adjusted air FL.

[0096] Like the exhaust-side heat sink 32B, the blower-side heat sink 32A is also covered with a fin cover 34. Therefore, in the blower-side heat sink 32A, when the air AR supplied from the blower fan 35 passes through the gaps between the fins, the temperature-adjusted air FL does not diffuse toward the exhaust-side heat sink 32B, etc., but is discharged from the air outlet 23 along the air direction adjustment wall 24 through the gaps between the fins in the blower-side heat sink 32A.

[0097] [2. Configuration of the airflow control device] Next, the airflow control device according to the first embodiment will be described with reference to Figs. 9 to 13. The airflow control device according to the present disclosure is an attachment that is attached to the air outlet 23 of the body air blower 2A or the like as described above. The airflow control device 3 according to the embodiment controls the flow of temperature-adjusted air FL blown out from the air outlet 23 of the body air blower 2A. The airflow control device 3 is made of resin.

[0098] Fig. 9 is a perspective view showing an airflow control device according to embodiment 1 when configured with the specifications according to example 1, and is a front view of the airflow control device shown in Fig. 9. Fig. 11 is a side view of the airflow control device shown in Fig. 9. Fig. 12 is a cross-sectional view taken along the arrow BB in Fig. 10.

[0099] In the airflow control device shown in Figure 9, the upper right-to-lower left direction is the W-axis direction, the lower right-to-upper left direction is the D-axis direction, and the up-down direction is the H-axis direction, and the directions defined in Figure 9 and subsequent figures related to the airflow control device follow the directions defined in Figure 9.

[0100] As shown in Fig. 9 to Fig. 12, in the first embodiment, the airflow control device 103A (airflow control device 3) having the configuration according to the first example corresponds to the airflow control device according to the present disclosure. As will be described in the second embodiment and onwards, the airflow control device 3 can be configured to have a number of different specifications. The airflow control device 103A is configured as one of such specifications.

[0101] The airflow control device 103A has a connection part 110, an introduction part 120A, a blowing part 130, and a flap 140. The connection part 110 is formed so as to be detachable from the airflow port 23 of the body air blower 2A by at least one fixing means of fitting, fastening, and engagement.

[0102] In the first embodiment, the connection part 110 is made of an elastic material such as silicone, silicone rubber, or rubber, and has a degree of flexibility that allows it to be easily elastically deformed by hand. The entire airflow control device 103A(3) may be made of an elastic material having such flexibility. Alternatively, only the connection part 110 of the airflow control device 103A(3) may be made of an elastic material having such flexibility.

[0103] The connecting part 110 is formed to have flexibility in a frame shape surrounding the entire circumference of the inlet 121 and including a recessed groove 111. The air supply control device 103A is attached in a state connected to the air outlet 23 of the body air supply device 2A by elastically deforming the connecting part 110 and fitting the groove 111 of the connecting part 110 into the flange 26 of the mounting side connecting part 25 of the body air supply device 2A.

[0104] In addition, as an example of a fixing means for connecting the airflow control device 103A(3) and the body air blower 2A, in embodiment 1, a fitting means formed by groove 111 of connection part 110 of the airflow control device 103A and flange 26 of the mounting side connection part 25 of the body air blower 2A was given.

[0105] However, in the air supply control device 103A(3), a fixed portion may be provided on the inner housing portion of the body air supply device 2, and a fixing portion may be provided on the connection portion of the air supply control device 3, and the fixing means may connect the fixed portion and the fixing portion, for example, by screw fastening or engagement of a convex portion and a concave portion, etc.

[0106] Alternatively, as a fixing means, one of the hook pieces provided on the airflow control device 3 is engaged with one of the engagement parts at one end of the opening in the inner housing part. In this state, the fixed part and the fixing part may be connected by engaging the other of the hook pieces provided on the airflow control device 3 with the other engagement part on the opposite side of the opening while elastically deforming.

[0107] As shown in Fig. 11, the airflow control device 103A is formed in a substantially L-shape in a side view. A hollow flow path FP is formed between the introduction section 120A and the blowing section 130 in a communicating manner. The flow path FP is formed between the inlet 121 of the introduction section 120A and the outlet 131 of the blowing section 130. In the flow path FP, in the outlet side flow path FPe passing through the blowing section 130, the cross-sectional area S1 of the outlet 131 is smaller than the cross-sectional area S2 of the inlet 121 of the introduction section 120.

[0108] The connection part 110 is connected to the flange 26 of the mounting side connection part 25. When mounted on the air outlet 23, the introduction part 120A is a part that takes in the temperature-adjusted air FL blown out from the air outlet 23 into the inlet 121 of the circulation path FP. The blowing part 130 is extended from the introduction part 120A and has an outlet 131 that sends the temperature-adjusted air FL that has passed through the circulation path FP to the outside.

[0109] 9 and 10, in the air flow control device 103A, the outlet side circulation path FPe in the blowing section 130 is divided into three by two partition walls 132. The two partition walls 132 are arranged in a slanted line such that the closer they are to the outlet port 131 side, the greater the distance between them.

[0110] In the configuration according to the first embodiment, a flap 140 is provided in the introduction section 120A. The flap 140 is a member that changes the direction of the temperature-adjusted air FL that flows through the flow path FP. As shown in Figs. 11 and 12, the flap 140 is swingable about a rotation shaft 141 provided in the introduction section 120A, and opens or closes an opening 142 formed in the introduction section 120A.

[0111] 12, when the flap 140 is opened, the temperature-adjusted air FL that has flowed into the inlet 121 is split into a main flow from the outlet 131 to the outside and a branch flow from an opening 142 that is oriented in a different direction from the outlet 131 and is then blown out. Conversely, when the flap 140 is closed, the temperature-adjusted air FL is blown out to the outside only as the main flow from the outlet 131.

[0112] Fig. 13 is a perspective view showing an airflow control device according to embodiment 1 configured according to the specifications of example 2. As shown in Fig. 13, an airflow control device 103B(3) configured according to example 2 also corresponds to the airflow control device according to the present disclosure.

[0113] In the configuration according to the second embodiment, airflow control device 103B has connection portion 110, introduction portion 120B, and blowing portion 130. Unlike airflow control device 103A, introduction portion 120B does not have a flap or an opening. Therefore, the temperature-adjusted air FL flows through a flow path FP that extends directly from the connection portion 110 side to the blowing portion 130 side, and is blown out to the outside.

[0114] <Embodiment 2> Next, an airflow control device according to embodiment 2 will be described with reference to Fig. 14 to Fig. 17. The airflow control device according to embodiment 2 differs from embodiment 1 in that it has two blowing parts.

[0115] In the second embodiment, the explanation will focus on the parts that are different from the first embodiment, and the explanation of the parts that are common to the first embodiment will be simplified or omitted by using symbols with the first digit being 2 and the last two digits being the same, such as, for example, connection unit 110 in the first embodiment and connection unit 210 in the second embodiment, where only the first digit is changed from 1 to 2 and the last two digits are the same, 10.

[0116] Fig. 14 is a perspective view showing an airflow control device according to embodiment 2, configured according to the specifications of example 1. Fig. 15 is a front view of the airflow control device shown in Fig. 14, and Fig. 16 shows a side view of the airflow control device. Fig. 17 is a cross-sectional view taken along the CC arrow in Fig. 16.

[0117] As shown in Figs. 14 to 16, in the second embodiment, an air-blowing control device 203A(3) having a configuration according to the first embodiment corresponds to the first air-blowing control device according to the present disclosure. The air-blowing control device 203A has a connection section 210, an introduction section 220A, a blowing section 230, and the like. The air-blowing control device 203A has a hollow flow path FP which is a flow path for the temperature-adjusted air FL. The flow path FP is formed to communicate between the introduction section 220A and the blowing section 230.

[0118] In the second embodiment, the connection part 210 is made of an elastic material such as silicone, silicone rubber, or rubber, and has flexibility that allows it to be easily elastically deformed by hand. The connection part 210 is in the shape of a frame that surrounds the entire circumference of the inlet 221, and is formed in a manner that includes a recessed groove 211. The air supply control device 203A(3) is attached in a state where it is connected to the air supply port 23 of the body air supply device 2A by elastically deforming the connection part 210 and fitting the groove 211 of the connection part 210 into the flange 26 of the attachment side connection part 25 of the body air supply device 2A(2).

[0119] In addition, in embodiment 2, as an example of a fixing means for connecting the airflow control device 203A and the body air blower 2A, a fitting means formed by groove 211 of connection portion 210 of the airflow control device 203A and flange 26 of the mounting side connection portion 25 of the body air blower 2A is given.

[0120] However, in the air supply control device 203A(3), a fixed portion may be provided on the inner housing portion of the body air supply device 2, and a fixing portion may be provided on the air supply control device 3, and the fixing means may connect the fixed portion and the fixing portion, for example, by screw fastening, engagement between a convex portion and a concave portion, etc.

[0121] Alternatively, as a fixing means, one of the hook pieces provided on the airflow control device 3 is engaged with one of the engagement parts at one end of the opening in the inner housing part. In this state, the fixed part and the fixing part may be connected by engaging the other of the hook pieces provided on the airflow control device 3 with the other engagement part on the opposite side of the opening while elastically deforming.

[0122] In air flow control device 203A, as shown in Fig. 14 to Fig. 16, blowing section 230 is formed in a manner in which it branches into two and bends in different directions with introduction section 220A as a boundary. That is, blowing section 230 is composed of first blowing section 230a and second blowing section 230b. First blowing section 230a and second blowing section 230b are arranged in a substantially V-shaped line symmetrical form on a virtual axis along the H-axis direction.

[0123] The angle of the V-shape between the first blowing section 130a and the second blowing section 130b with respect to a virtual axis along the H-axis direction is not particularly limited and can be changed as appropriate. The inclination angle of the first blowing section 230a and the inclination angle of the second blowing section 330b may be different.

[0124] Of the flow paths FP, in the outlet-side flow path FPe passing through the first blowing section 230a, the cross-sectional area S1 of the first outlet 231a is smaller than the cross-sectional area S2 of the inlet 221 of the introduction section 220. Similarly, in the outlet-side flow path FPe passing through the second blowing section 230b, the cross-sectional area S1 of the second outlet 231b is smaller than the cross-sectional area S2 on the introduction section 220 side.

[0125] In the airflow control device 203A, when the temperature-adjusted air FL is blown into the inlet 221 of the introduction section 220A, it is blown out from the introduction section 220A to the outside through the first outlet 231a via the outlet-side flow path FPe of the first blowing section 230a. At the same time, the temperature-adjusted air FL is blown out from the introduction section 220A to the outside through the second outlet 231b via the outlet-side flow path FPe of the second blowing section 230b.

[0126] That is, in the airflow control device 203A, the temperature-adjusted air FL is split into a substantially V-shaped flow and blown out from the first outlet 231a of the first blowing section 230a and the second outlet 231b of the second blowing section 230b.

[0127] Fig. 18 is a cross-sectional view of an airflow control device according to embodiment 2 configured with the specifications according to example 2, as viewed from a position corresponding to the CC arrow position in Fig. 16. As shown in Fig. 18, airflow control device 203B(3) configured according to example 2 also corresponds to the airflow control device according to the present disclosure.

[0128] In the configuration according to the second embodiment, the air flow control device 203A has a connection part 210, an introduction part 220A, a blowing part 230, a flap 240, and the like. In the configuration according to the second embodiment, the flap 240 is provided in the introduction part 220B. As shown in Fig. 18, the flap 240 can swing around a rotation shaft 241 provided in the introduction part 220B, and opens or closes an opening 242 formed in the introduction part 220B.

[0129] <Embodiment 3> Next, an airflow control device according to embodiment 3 will be described with reference to Fig. 19 to Fig. 24. The airflow control device according to embodiment 3 differs from embodiment 2 in that the two blowing units are arranged on opposite sides to each other in one direction.

[0130] In the third embodiment, the explanation will focus on the parts that are different from the second embodiment, and the explanation of the parts that are common to the first and second embodiments will be simplified or omitted by using symbols with the first digit being 2 and the last two digits being the same, such as connection unit 110 in the first embodiment and connection unit 310 in the third embodiment, where only the first digit is changed from 1 to 3 and the last two digits are the same, 10.

[0131] Fig. 19 is a perspective view of an airflow control device according to embodiment 3 as viewed from the outside, and a perspective view of the airflow control device as viewed from the inside is shown in Fig. 20. Fig. 21 is a front view of the airflow control device shown in Fig. 20 as viewed from the inside, and Fig. 22 shows a cross-sectional view taken along the line EE in Fig. 21.

[0132] As shown in Fig. 19 to Fig. 22, an air-blowing control device 303(3) according to the third embodiment corresponds to the first air-blowing control device according to the present disclosure. The air-blowing control device 303 has a connection section 310, an introduction section 320, a flow guide section 325, a blowing section 330, and the like. The air-blowing control device 303 has a hollow flow path FP which is a flow path for the temperature-adjusted air FL. The flow path FP is formed to communicate between the introduction section 320 and the blowing section 330.

[0133] In the third embodiment, the connection part 310 is made of an elastic material such as silicone, silicone rubber, or rubber, and has flexibility to the extent that it can be easily elastically deformed by hand. The connection part 310 is formed in a frame shape surrounding the entire periphery of the inlet 321, and includes a recessed groove 311.

[0134] In addition, in embodiment 2, as an example of a fixing means for connecting the airflow control device 303(3) and the body air blower 2A, a fitting means is given by a groove 311 of the connection part 310 of the airflow control device 303 and a flange 26 of the mounting side connection part 25 of the body air blower 2A.

[0135] However, in the air supply control device 303(3), a fixed portion is provided on the inner housing portion of the body air supply device 2, and a fixing portion is provided on the connection portion of the air supply control device 3, and the fixing means may connect the fixed portion and the fixing portion, for example, by screw fastening, engagement between a convex portion and a concave portion, etc.

[0136] Alternatively, as a fixing means, one of the hook pieces provided on the airflow control device 3 is engaged with one of the engagement parts at one end of the opening in the inner housing part. In this state, the fixed part and the fixing part may be connected by engaging the other of the hook pieces provided on the airflow control device 3 with the other engagement part on the opposite side of the opening while elastically deforming.

[0137] In the air flow control device 303(3), as shown in Figs. 19 to 22, the blowing section 330 is formed in a manner in which it is branched and bent into two parts in the diametrically opposite directions with the introduction section 320 as a boundary in the H-axis direction. That is, the blowing section 230 is composed of a first blowing section 330a and a second blowing section 330b. Both the first blowing section 230a and the second blowing section 230b are arranged in a form that is slightly inclined from the introduction section 320 toward the connection section 310 side with respect to the D-axis direction.

[0138] The angle at which first blowing section 330a and second blowing section 330b are inclined from introduction section 320 toward connection section 310 with respect to the D-axis direction is not particularly limited and can be changed as appropriate. The inclination angle of first blowing section 330a and the inclination angle of second blowing section 330b may be different.

[0139] In the first blowing section 330a, the outlet 331 is divided into two first outlets 331a by a partition wall 332. Similarly, in the second blowing section 330b, the outlet 331 is divided by a partition wall 332 into two first outlets 331b.

[0140] Of the flow paths FP, in both of the outlet-side flow paths FPe passing through the first blowing section 330a, the cross-sectional area S1 of the first outlet 331a is smaller than the cross-sectional area S2 of the inlet 321 of the introduction section 320. Similarly, in the outlet-side flow path FPe passing through the second blowing section 330b, the cross-sectional area S1 of the second outlet 331b is smaller than the cross-sectional area S2 on the introduction section 320 side.

[0141] 22, the flow guide 325 is formed in the flow path FP in the introduction section 320. The flow guide 325 is provided to guide the temperature-adjusted air FL taken into the introduction section 320 so that it can easily flow toward the first blowing section 330a and the second blowing section 330b. The flow guide 325 allows the temperature-adjusted air FL to flow along the flow path FP surrounded by the inner wall of the airflow control device 303 while suppressing excessive turbulence caused by a decrease in flow speed and pressure loss when the temperature-adjusted air FL flows along the inner wall, and flows along the flow path FP toward the outlet 331.

[0142] In particular, in the airflow control device 303, the temperature-adjusted air FL is split and blown out in opposite directions to the first outlet 331a of the first blowing section 330a and the second outlet 331b of the second blowing section 330b.

[0143] Therefore, when the temperature-adjusted air FL is blown into the inlet 321 of the introduction section 320 of the airflow control device 303, it flows smoothly from the introduction section 320 to the first blowing section 330a, and is blown out to the outside from the first outlet 331a through the outlet-side flow path FPe. At the same time, the temperature-adjusted air FL flows smoothly from the introduction section 320 to the second blowing section 330b, and is blown out to the outside from the second outlet 331b through the outlet-side flow path FPe.

[0144] Fig. 23 is an explanatory perspective view showing an air-blowing control device according to embodiment 2 before it is connected to the mounting-side connector of the body air blower illustrated in embodiment 1. Fig. 24 is an explanatory perspective view showing an air-blowing control device according to embodiment 2 connected to the mounting-side connector of the body air blower illustrated in embodiment 1.

[0145] The air blowing control device 303(3) is attached in a connected state to the air blowing port 23 of the body blower 2B by fitting the groove 311 of the connection part 310 into the flange 26 of the attachment side connection part 25 of the body blower 2B(2) due to the elastic deformation of the connection part 310, as shown in Figures 23 and 24.

[0146] As shown in Figures 23 and 24, in the case of a body blower 2B(2) having a supported part 16 at the four corners of a housing 10 that can be connected to a band-shaped support member 700 such as a belt or string, for example, a person can use the body blower 2B(2) with an air blowing control device 303 attached to the air outlet 23 by suspending it from the support member 700 connected to the supported part 16.

[0147] In the body blower 2B(2), the housing 10 is configured with an outer housing portion 11 and an inner housing portion 12B(12) which are separate bodies. The outer housing portion 11 is the same for the body blower 2A(2) and the body blower 2B(2), and the body blower 2B(2) is configured by changing the inner housing portion 12A(12) of the body blower 2A(2) to the inner housing portion 12B(12).

[0148] <Fourth embodiment> Next, an airflow control device according to embodiment 4 will be described with reference to Fig. 25 to Fig. 29. The airflow control device according to embodiment 3 differs from embodiment 2 in that the two blowing units are arranged on opposite sides to each other in one direction.

[0149] In the fourth embodiment, the following description will focus on the parts that are different from the first to fourth embodiments, and the description of the parts that are common to the first to third embodiments will be simplified or omitted by using a symbol with the first digit being 4 and the last two digits being the same, for example, since the connection part 410 in the fourth embodiment is the same as the connection part 110 in the first embodiment, only the first digit is changed from 1 to 4 and the last two digits remain the same, that is, 10.

[0150] Fig. 25 is a perspective view showing an air-blowing control device according to embodiment 4, and Fig. 26 shows a front view of the air-blowing control device. Fig. 27 is a cross-sectional view taken along the line FF in Fig. 26. Fig. 28 is an explanatory diagram showing an air-blowing control device according to embodiment 4 in a perspective view before it is connected to the mounting-side connector of the body air-blowing device exemplified in embodiment 1. Fig. 29 is an explanatory diagram showing an air-blowing control device according to embodiment 4 in a perspective view after it is connected to the mounting-side connector of the body air-blowing device exemplified in embodiment 1.

[0151] As shown in Fig. 25 to Fig. 29, air-blowing control device 403(3) according to embodiment 4 corresponds to the second air-blowing control device according to the present disclosure. Air-blowing control device 403 has a connection part 410, an introduction part 420, a blowing part 430, a fixing part 450, and the like. Air-blowing control device 403 has a hollow flow path FP which is a flow path for temperature-adjusted air FL. Flow path FP is formed to communicate between introduction part 420 and blowing part 430.

[0152] 25 to 28, connection part 410 is formed in a frame shape surrounding the entire periphery of inlet 421 of introduction part 420. In air flow control device 403, one blowing part 430 is formed in a shape bent downward in the H-axis direction in a substantially J-shape, with introduction part 420 as the boundary. Blowing part 430 has a wall member 432 surrounding flow path FP, and a plurality of protrusions 433 protruding from wall member 432.

[0153] Of the circulation paths FP, in the outlet side circulation path FPe that passes through the blowing section 430, the blowing section 430 is formed in a shape that is narrower on the outlet 431 side than on the introduction section 420 side so that the cross-sectional area S1 on the outlet 431 side is smaller than the cross-sectional area S2 on the inlet 421 side of the introduction section 420. Therefore, a wall member outer surface 432a of the wall member 432 is inclined downward in the H-axis direction.

[0154] As shown in Fig. 28 and Fig. 29, when the connection part 410 is attached to the body blower 2C(2), the protrusions 433 of the wall member 432 are formed in a portion facing the inner housing part 12C of the body blower 2C. Specifically, the multiple protrusions 433 are formed on the wall member outer surface 432a along the H-axis direction. Moreover, the multiple protrusions 433 are aligned along the Y-axis direction with a certain gap between adjacent protrusions 433. As shown in Fig. 27, all of the protrusions 433 are provided in a protruding shape in a mountain shape when viewed from the side in the Y-axis direction.

[0155] In the body blower 2C(2), the housing 10 has an outer housing portion 11 and an inner housing portion 12C(12) which are separate bodies. The outer housing portion 11 is the same for the body blower 2A(2) and the body blower 2C(2), and the body blower 2C(2) is constructed by changing the inner housing portion 12A(12) of the body blower 2A(2) to the inner housing portion 12C(12).

[0156] The inner housing 12C has a fixed portion 50 formed to be engageable with a fixing portion 450 of the air supply control tool 403. The fixing portion 450 corresponds to the fixing portion according to the present disclosure. Specifically, the fixing portion 450 is formed in the connection portion 410 for connecting with the body blower 2C. On the other hand, the fixed portion 50 is formed in the inner housing 12C of the body blower 2C. The fixed portion 50 corresponds to the fixing portion according to the present disclosure.

[0157] In the fourth embodiment, the fixing portion 450 has an engagement piece 451 at one location below the connecting portion 410 (lower side in the H-axis direction in FIG. 25) and two screw fastening portions 452 at both left and right sides of the engagement piece 451 (both sides in the W-axis direction in FIG. 25) and above the connecting portion 410 (upper side in the H-axis direction in FIG. 25). The engagement piece 451 is formed in a substantially L-shape. The claw of the engagement piece 451 has flexibility within the range of elastic deformation. The screw fastening portion 452 is formed, for example, in a manner including a female screw in a boss that can be screwed with an inserted male screw, or in a manner in which a nut is inserted into the boss.

[0158] In the fourth embodiment, fixed portion 50 has one engagement groove 51 below air outlet 23 (lower side in the H-axis direction in FIG. 28) and two screw fastening portions 52 on both the left and right sides of engagement groove 51 (both sides in the W-axis direction in FIG. 28) and above air outlet 23 (upper side in the H-axis direction in FIG. 28). Engagement groove 51 is formed in a form having a groove that can engage with the tip of engagement piece 451. Screw fastening portion 52 has a through hole through which a screw fastening member such as a screw or a bolt can be inserted.

[0159] When attaching the connection part 410 to the inner housing part 12C(12) of the body blower 2C(2), the engagement piece 451 of the fixing part 450 of the airflow control tool 403(3) is first engaged with the engagement groove 51 of the fixed part 50 of the inner housing part 12C. Next, the fixing part 450 and the fixed part 50 are fixed by screwing, so that the airflow control tool 403 is connected and attached to the body blower 2. This connects the airflow port 23 of the body blower 2 and the connection part 410 of the airflow control tool 403.

[0160] When the airflow control device 403(3) is attached to the body airflow device 2C(2), the temperature-adjusted air FL is blown into the inlet 421 of the introduction section 420 of the airflow control device 403(3), and the air flows smoothly from the introduction section 420 to the outlet section 430 and is blown out to the outside from the outlet 431 via the outlet side circulation path FPe.

[0161] In the fourth embodiment, the fastening of the fixing part 450 and the fixed part 50 with screws is given as an example of a fastening means for connecting the airflow control tool 403(3) and the personal air blower 2C.

[0162] However, in the case of the air blowing control device 3, the air blowing control device 3 may be attached to the body air blowing device 2 by a fitting means between a groove of the connection part formed in a frame shape, such as the connection part 110 in embodiment 1, and a flange of the attachment side connection part formed at the air outlet of the body air blowing device 2.

[0163] [3.

[0168] The body air blowing device with an airflow control device 1A, 1B(1) according to the fifth embodiment corresponds to the body air blowing device with an airflow control device according to the present disclosure.

[0169] 30 to 35, the body air blower with air blower control device 1A is a first aspect of the device in the first embodiment, which is composed of an air blower control device 103A, a body air blower 2D, and a cap attachment part 550, as shown in Fig. 9 etc. Note that an air blower control device 103B(3) may be attached instead of the air blower control device 103A(3).

[0170] As shown in FIG. 36 and FIG. 37, the body air blowing device 1B with the air blowing control device is 13 and the like, the first embodiment is a device of the second aspect, which is made up of an airflow control device 203B, a body airflow device 2D, and a cap attachment part 550. Note that an airflow control device 203A may be attached instead of the airflow control device 203B.

[0171] The body blower 2D(2) will be described with reference to Figures 30 and 31. As shown in Figures 30 and 31, in the body blower 2D(2), the housing 10 is composed of an outer housing portion 11 and an inner housing portion 12D(12), which are separate bodies. A holding guide portion 510 is formed on the flat surface 12d of the inner housing portion 12D. The holding guide portion 510 corresponds to the fixing portion according to the present disclosure.

[0172] As shown in Fig. 30, the holding guide part 510 has a pair of two guide members 511. The guide members 511 are formed in a substantially L-shape, and the tip of the guide member 511 is a holding piece 512. The two guide members 511 are arranged facing each other with the holding pieces 512 spaced apart in the W-axis direction, and extend parallel to each other along the H-axis direction and stand on the flat plate surface 12d. The holding guide part 510 fixes and holds the attached cap body mounting part 550.

[0173] 30 to 35, the cap body attachment part 550 is an auxiliary member for attaching the body air blower with an air blowing control device 1A, 1B(1) to the cap body 571 of the helmet 570 together with a belt-shaped member 580. The belt-shaped member 580 is a well-known member formed in a belt shape such as a rubber belt or a band whose length is adjustable.

[0174] In addition, when attaching the body blower device 1 with airflow control device to the cap body 571, other than using the belt-shaped member 580, the body blower device 1 with airflow control device and the cap body attachment part 550 may be connected by a connection means that can be easily attached and detached, such as screw fastening or engagement with a snap button.

[0175] 30, the cap body attachment part 550 is formed in a generally plate-like shape warped in an arc shape to match the outer peripheral shape of the surface of the cap body 571. The cap body attachment part 550 has a base part 551 in the center, and has a band attachment part 553 on each end.

[0176] The base 551 has engagement grooves 552 in two locations. The engagement grooves 552 are formed to be engageable with guide members 511 of a holding guide portion 510 arranged in the body blower 2D(2). At both locations, the engagement grooves 552 are inserted into the guide members 511, and the base 551 is held by the holding pieces 512 of the guide members 511, whereby the cap attachment portion 550 is fixed to the holding guide portion 510.

[0177] Each of the band attachment parts 553 has an attachment hole 554 through which a band-shaped member 580 can be inserted. As shown in Figures 32 to 35 and 37, when attaching the body blower device 1A with an airflow control device, the body blower device 1B with an airflow control device, etc. to the cap body 571 of a helmet 570, first, the cap body attachment part 550 is connected to the holding guide part 510 of the body blower device 2D.

[0178] Next, as shown in Figures 33 and 34, a belt-shaped member 580 is wound around the outer peripheral edge at the lower end of the cap body 571, and this belt-shaped member 580 is inserted into the mounting hole 554 of the cap body mounting part 550 attached to the body blower 2D (12) of the body blower 1A etc. (1) with air flow control device.

[0179] Next, the airflow control device 103A is placed in close proximity to the outer peripheral edge of the cap body 571, and with the cap body attachment part 550 in close contact with the cap body 571, the body air blower with airflow control device 1A(1) is fastened and attached to the cap body 571 by the belt-shaped member 580 with a tightening tension adjusted so that it will not fall off.

[0180] In the case of the body blower 1A with an airflow control device, as shown in Figures 34 and 35, the temperature-adjusted air FL is blown out from the air outlet 23 of the body blower 2D through the outlet 131 of the airflow control device 103A. As a result, the temperature-adjusted air FL is blown toward the top of the head and the surrounding area through the internal helmet space 570S between the head of the user HM wearing the helmet 570 and the hat body 571.

[0181] Furthermore, when the flap 140 of the airflow control device 103A is open, the temperature-adjusted air FL is blown toward the neck of the user HM as well as toward the helmet interior space 570S.

[0182] In the case of the body air blower with air blowing control device 1B, as shown in Fig. 37, the temperature-adjusted air FL is blown out from the air blowing port 23 of the body air blower 2D through the outlet 131 of the air blowing control device 203B. As a result, the temperature-adjusted air FL is blown into the helmet interior space 570S, toward the head of the user HM wearing the helmet 570, along the scalp.

[0183] As described above, the body blower 1A, 1B with the airflow control device including the body blower 2D is an example of the body blower with airflow control device attached to the cap body 571 of the helmet 570.

[0184] However, as described later, the body blower with airflow control device attached to the cap body 571 of the helmet 570 also applies to the body blower with airflow control device 1X (1Xu, 1Xv) including the body blower 2E in embodiment 9. However, when using the body blower with airflow control device (1Xu, 1Xv), it is important that the holding guide part 510 is formed in the inner housing part corresponding to the inner housing part 812 of the body blower with airflow control device 2E of the body blower with airflow control device (1Xu, 1Xv).

[0185] That is, in a body blower configured as a body blower with an airflow control device attached to the cap body 571 of helmet 570, a housing may be configured by a first inner housing part having a fixing part provided in the inner housing part 812, and an outer housing part 811. The fixing part is a holding guide part configured in a manner that is detachable from the cap body attachment part 550, like the holding guide part 510 of the body blower 2D.

[0186] <Sixth embodiment> Next, a body air blowing device with an air blowing control device according to a sixth embodiment will be described with reference to Figs.

[0187] In the sixth embodiment, the differences from the first to fifth embodiments will be mainly described, and the description of the parts common to the first to fifth embodiments will be simplified or omitted by using the same reference numerals.

[0188] Fig. 38 is a perspective view showing a first example of the use of a body blower device with airflow control device according to embodiment 6 attached to a collar of clothing. Fig. 39 shows the state before the body blower device with airflow control device according to embodiment 6 is attached to the collar of clothing, and Fig. 40 is an explanatory diagram showing the state of using the body blower device with airflow control device after it is attached to the collar of clothing. Fig. 41 is a schematic diagram showing the air flow inside clothing when the body blower device with airflow control device according to embodiment 6 is attached to the collar.

[0189] As shown in Figures 38 to 41, the body air blower with air blowing control device 1C(1) is a third type of device in embodiment 4, which is composed of an air blowing control device 403(3) and a body air blower 2C(2) as shown in Figure 29 etc.

[0190] In the body blower 2C(2), the housing 10 is composed of an outer housing portion 11 and an inner housing portion 12C(12), which are separate bodies. The inner housing portion 12C has a fixed portion 50 formed so as to be engageable with a fixing portion 450 of the airflow control device 403(3). The fixing portion 450 corresponds to the fixing portion according to the present disclosure. The fixed portion 50 corresponds to the fixing portion according to the present disclosure.

[0191] The air blowing control device 403(3) is attached to the body air blowing device 2 by connecting the inner housing part 12C with the engagement piece 451 of the fixing part 450 and the engagement groove 51 of the fixed part 50 of the inner housing part 12C(12) and fastening the fixing part 450 and the fixed part 50 with screws.

[0192] <First example of use of a body air blowing device with air blowing control device> As shown in Figures 39 and 40, the body blower with airflow control device 1C(1) has a clothing attachment part 60 that can be attached to the collar 610 of clothing 600 worn by the user HM, the edge near the buttons of a shirt, the sleeve, etc. Specifically, as shown in Figures 25, 28, 39 and 40, the clothing attachment part 60 is a gap formed by being sandwiched between the wall member outer surface 432a and the protrusion 433 of the wall member 432 of the airflow control device 403 and the flat surface 12a of the inner housing part 12C of the housing 10 of the body blower 2C.

[0193] The clothing attachment portion may be a member connectable to clothing, such as a gripping means such as a clip, or a snap button.

[0194] When attaching the body blower device with airflow control device 1C(1) to the collar 610 of clothing 600, the user HM inserts the collar 610 into the clothing attachment part 60 as shown in Figures 39 and 40, thereby inserting the outlet 431 of the airflow control device 403 of the body blower device with airflow control device 1C into the inside of the clothing 600. At this time, as shown in Figure 41, the collar 610 is held in a stable state because it is sandwiched between the wall member outer surface 432a and protrusion 433 of the airflow control device 403 and the flat surface 12a of the inner housing part 12C.

[0195] Furthermore, when the body air blower with airflow control device 1C is attached to the collar 610 of the clothing 600, the blowing section 430 of the airflow control device 403 is disposed between the clothing 600 and the body of the user HM, as shown in Fig. 41. This allows the temperature-adjusted air FL to be blown toward the upper body, such as the back and neck, of the user HM.

[0196] <Embodiment 7> Next, a body air blowing device with an air blowing control device according to a seventh embodiment will be described with reference to Figs.

[0197] In the seventh embodiment, the differences from the first to sixth embodiments will be mainly described, and the description of the parts common to the first to sixth embodiments will be simplified or omitted by using the same reference numerals.

[0198] Fig. 42 is a front view of a body blower with airflow control device according to embodiment 7, and is a diagram illustrating the configuration when directly attached to the body. Fig. 43 is a perspective view of the body blower with airflow control device shown in Fig. 42 attached directly to the body, viewed from behind the body. Fig. 44 is a diagram of the body blower with airflow control device shown in Fig. 42 being used, viewed from the side of the body. Fig. 45 is a schematic diagram showing the air flow reaching the body by the body blower with airflow control device shown in the cross-sectional view taken along the line AA in Fig. 42.

[0199] As shown in Figures 42 to 45, the body air blower with air blowing control device 1D(1) is a fifth aspect of the device in the third embodiment, which is composed of an air blowing control device 303(3) and a body air blower 2B(2) as shown in Figure 24 etc.

[0200] <Second example of use of the body air blower with air blowing control device> In the body blower 1D(1) with airflow control device, as shown in Figures 23 and 24, the airflow control device 303(3) is attached in a connected state to the airflow port 23 of the body blower 2B(2). The airflow control device 303 is connected by fitting the groove 311 of the connection part 310 with the flange 26 of the mounting side connection part 25 of the body blower 2A due to elastic deformation of the connection part 310. The airflow control device 303 and the body blower 2A are detachable.

[0201] As shown in Figures 23 and 24, the body blower 2B has supported parts 16 formed at the four corners of the inner housing 12C. As a result, as shown in Figures 42 to 44, a band-like support member 700 such as a belt or string can be connected to the supported parts 16. When the user HM wears the body blower 1D with airflow control device directly on the upper body, arms, legs, or other parts of the body, the user HM can use the body blower 1D with airflow control device by anchoring it with the support member 700, positioning it on the user HM's body and maintaining it in direct contact with the body.

[0202] Specifically, as shown in Fig. 43, when the body blower device 1D(1) with an airflow control device is used on the upper body of a user HM, the user HM can use the body blower device 1D with an airflow control device 303(3) attached to the air outlet 23 by suspending it across the upper body of the user HM using a support member 700 connected to the supported part 16. In this way, as shown in Fig. 45, the temperature-adjusted air FL is blown along the body surface of the user HM at the position where the body blower device 1D with an airflow control device is placed, including the upper body such as the back and neck of the user HM.

[0203] <Embodiment 8> Next, a personal air blowing device with an air blowing control device according to an eighth embodiment will be described with reference to Figs.

[0204] In the eighth embodiment, the differences from the first to seventh embodiments will be mainly described, and the description of the parts common to the first to seventh embodiments will be simplified or omitted by using the same reference numerals.

[0205] <Third example of use of the body air blower with air blowing control device> Fig. 46 is a perspective view showing a third example of use in which the body air blower with air blowing control device according to embodiment 8 is stored in a clothing pocket. Fig. 47 is a schematic diagram showing the air flow reaching the body when the air blowing control device according to embodiment 4 is used with the body air blower with air blowing control device according to embodiment 8. Fig. 48 is a schematic diagram showing the air flow reaching the body when the air blowing control device according to embodiment 3 is used with the body air blower with air blowing control device according to embodiment 8.

[0206] As described above, in addition to the air blower for body with air blowing control device 1C(1), the air blower for body with air blowing control device 1D(1) is stored in a pocket 620 of clothing 600B as shown in Fig. 46. In the air blower for body with air blowing control device 1C(1), the air blowing control device 403(4) and the air blower for body 2C(2) are detachable. In the air blower for body with air blowing control device 1D(1), the air blowing control device 303(3) and the air blower for body 2A(2) are detachable.

[0207] <Third example of use of the body air blower with air blowing control device> 47 and 48, an opening 621 is formed in a pocket 620 of clothing 600B by opening a part of clothing 600B, and the opening 621 penetrates between the inside of the pocket 620 and the body side of clothing 600B, sandwiching the fabric of clothing 600B. The pocket 620 is formed with a size that allows the air outlet 23 of the body blower 1C and the connection part 410 and introduction part 420 of the air blower control device 403 to be connected between the inside of the pocket 620 and the body side of clothing 600B.

[0208] When a user HM uses the body air blower device 1C(1) with air blowing control device by placing it in the pocket 620 of the clothing 600B as shown in FIG. 47, the temperature-adjusted air FL is blown out from the outlet 431 of the blowing section 430 of the air blowing control device 403(4) and is blown along the body surface of the user HM toward the lower body side of the clothing 600B.

[0209] 48, when a user HM uses the body air blower device 1D(1) with an air blowing control device in a pocket 620 of clothing 600B, the temperature-adjusted air FL is blown out from the first outlet 331a of the first blowing section 330a of the air blowing control device 303(3) along the body surface of the user HM and directed toward the upper body, neck, etc. above the pocket 620. At the same time, the temperature-adjusted air FL is blown out from the second outlet 331b of the second blowing section 330b of the air blowing control device 303(3) along the body surface of the user HM and directed toward the lower body below the pocket 620.

[0210] In the body blower 1D(1) with airflow control device, as shown in Figures 23 and 24, the airflow control device 303(3) is attached in a connected state to the air outlet 23 of the body blower 2B. The airflow control device 303(3) is connected by fitting the groove 311 of the connection part 310 with the flange 26 of the mounting side connection part 25 of the body blower 2A(2) due to elastic deformation of the connection part 310. The airflow control device 303(3) and the body blower 2A(2) are detachable.

[0211] Here, the position of the pocket 620 provided on the clothing 600B will be briefly explained. When the human body is exposed to a hot environment, the heat puts it at risk of causing heat stroke and has a significant adverse effect on the autonomic nervous system. Therefore, as a preventative measure, it is necessary to first cool the blood in the arteries flowing to the brain, and it is required to promote sweating and maintain normal body temperature regulation.

[0212] In order to effectively cool the blood flowing to the brain, it is said that cooling the arteries in the neck, armpits, and groin is effective.

[0213] In the case of the neck, the carotid arteries are located not only around the hairline at the back of the neck, but also on both sides of the throat, and when the blood is cooled by blowing cold air over the areas that touch the arteries, the cooled blood circulates throughout the body, helping to lower body temperature.

[0214] The armpit is the area where the thermometer is placed, and is also where the arteries are located. The armpit arteries run toward the arm, and when the blood in the arteries under the armpit or in the soft part near the inside of the upper arm is cooled, the cooled blood circulates throughout the body. This helps to lower body temperature.

[0215] Moreover, by exposing your armpits to cool air, the evaporation of sweat from your armpits lowers the surface temperature of your skin, giving you a feeling of coolness. At the base of your thigh, there is a large artery that runs to your feet, located in the inner third of the line connecting the front of your thigh, your hipbone, and your crotch. When the blood in this large artery is cooled, the cold blood circulates throughout your body. This helps to lower your body temperature.

[0216] Based on this knowledge, in order to cool the arteries in the neck and armpits, and if necessary, the arteries in the groin, pockets 620 are formed in the garment 600B in areas corresponding to the neck and armpits, and in areas corresponding to the groin, as shown in FIG. 46.

[0217] The body air blower 1C(1) with air blowing control device housed in these pockets 620 blows cold air CF from the cold air port directly or in close proximity to the neck, armpits, and / or groin, thereby cooling the body of the wearer of the garment 600B.

[0218] <Embodiment 9> Next, a body blower according to embodiment 9 will be described with reference to Figures 49 to 54. Compared to the body blower given as an example of a device to which the airflow control tool according to embodiment 1 is attached, this differs in the structure of the housing and in that it has an airflow direction changing member.

[0219] In the ninth embodiment, the following description will focus on the parts that are different from the first to eighth embodiments, and the description of the parts that are common to the first embodiment, etc. will be simplified or omitted by using symbols with the first digit being 2 and the last two digits being the same, such as the internal space 10S of the first embodiment and the space 810S of the ninth embodiment, where only the first digit is changed from 1 to 8 and the last two digits are the same, 10.

[0224] 51 and 54, an airflow direction adjusting wall 824 is disposed in the housing 810. The airflow direction adjusting wall 824 is a wall member that separates the flow path of the temperature-adjusted air FL and the flow path of the exhaust air EX between the Peltier element unit 30 and the exhaust port 22 in order to prevent mixing of the temperature-adjusted air FL that has passed through the blower-side heat sink 32A and the exhaust air EX that has passed through the exhaust-side heat sink 32B.

[0225] 49, the outer housing unit 811 has a flat plate portion 811a extending along the X-axis direction and the Y-axis direction, and a side end portion 811b extending along the Y-axis direction and the Z-axis direction. The inner housing unit 812 has a flat plate portion 812a extending along the X-axis direction and the Y-axis direction, and a side end portion 812b extending along the Y-axis direction and the Z-axis direction.

[0226] In the body blower 2E, the flat plate portion 812a of the inner housing portion 812 forms a first side portion 813a of the housing 810. The first side portion 813a corresponds to the first side portion according to the present disclosure. Furthermore, a side end portion 811b of the outer housing portion 811 and a side end portion 812b of the inner housing portion 812 are flush with each other and form a second side portion 813b of the housing 810. The second side portion 813b corresponds to the second side portion according to the present disclosure.

[0227] A first side portion 813a extending along the X-axis direction and a second side portion 813b extending along the Z-axis direction share a connecting portion 814 where they are adjacently connected at a corner of the housing 810. The housing 810 forming the cover of the body blower 2E includes a surrounding notch 815 as shown in Figs.

The surrounding notch 815 is provided at a corner of the housing 810 where a connection point 814 between the first side portion 813a and the second side portion 813b is located.

[0229] The surrounding missing portion 815 has three engagement grooves 850 formed in the end surface of the first side portion 813a. The second side portion 813b also has three engagement grooves 850 formed in the end surface of the side end portion 811b.

[0230] The airflow direction changing member 900 comprises a base 910, an opening 921, a blocking portion 922, an engagement piece 925, and a handle 926. The base 910 is formed in a substantially L-shaped plate shape. One plate portion of the base 910 serves as the opening 921, and another plate portion perpendicular to the first plate portion serves as the blocking portion 922.

[0231] The opening 921 is a through hole formed in a manner that allows the temperature-adjusted air FL to circulate to the outside. An engagement piece 925 is provided on the plate portion where the opening 921 is located in a manner that allows it to engage with the engagement groove 850. The engagement piece 925 is provided on the end face of the plate portion so as to protrude toward the X-axis.

[0232] The blocking portion 922 is a lid that blocks the flow of the temperature-adjusted air FL to the outside. A handle 926 and an engagement piece 925 are provided on a plate portion on which the blocking portion 922 is provided. One engagement piece 925 is provided on an end face of the blocking portion 922 so as to protrude toward the Z-axis, and two engagement pieces 925 are provided along the Y-axis direction.

[0233] The airflow direction changing member 900 is disposed in the surrounding gap 815 as part of the housing and attached to the housing 810. The airflow direction changing member 900 can be attached to the surrounding gap 815 in a first arrangement configuration, and can also be attached to the surrounding gap 815 in a second arrangement configuration.

[0234] As shown in Figures 49 to 51, the first arrangement is an arrangement in which the opening 921 of the air direction changing member 900 is arranged on the first side 813a side, and the blocking portion 922 of the air direction changing member 900 is arranged on the second side 813b side. As shown in Figures 52 to 54, the second arrangement is an arrangement in which the opening 921 of the air direction changing member 900 is arranged on the second side 813b side, and the blocking portion 922 of the air direction changing member 900 is arranged on the first side 813a side.

[0235] When attaching the air direction variable member 900 to the housing 810 in the first arrangement form, the air direction variable member 900 is attached to the housing 810 by engaging the two engagement pieces 925 on the blocking portion 922 side of the air direction variable member 900 with the two engagement groove portions 850 on both sides of the second side portion 813b, and then engaging the engagement piece portion 925 on the opening portion 921 side of the air direction variable member 900 with the two engagement groove portions 850 on both sides of the first side portion 813a.

[0236] When the air direction changing member 900 is attached to the housing 810 in the first arrangement form, as shown in FIG. 51, the temperature-adjusted air FL generated by the body blower 2E is blown out from an opening 921 located on the inner housing portion 812 (first side portion 813a) side of the body blower 2E.

[0237] Furthermore, when the air direction variable member 900 is attached to the housing 810 in the second arrangement form, the air direction variable member 900 is attached to the housing 810 by engaging the two engaging pieces 925 on the blocking portion 922 side of the air direction variable member 900 with the two engaging grooves 850 on both sides of the first side portion 813a, and then engaging the engaging piece 925 in the center of the blocking portion 922 side of the air direction variable member 900 with the engaging groove 850 in the center of the second side portion 813b.

[0238] When the air direction changing member 900 is attached to the housing 810 in the second arrangement form, as shown in FIG. 54, the temperature-adjusted air FL generated by the body blower 2E is blown out from the opening 921 located on the second side 813b of the body blower 2E.

[0239] <Embodiment 10> Next, a personal air blowing device with an air blowing control device according to a tenth embodiment will be described with reference to FIG.

[0240] In the tenth embodiment, the differences from the ninth embodiment will be mainly described, and the description of the parts common to the ninth embodiment will be simplified or omitted by using the same reference numerals.

[0241] Fig. 55 is a perspective view showing a body air blower with air blowing control device of embodiment 10 in which an air blowing control device of embodiment 4 is attached to the body air blower shown in Fig. 50. As shown in Fig. 55, body air blower with air blowing control device 1Xu (1X) is a seventh aspect of the device consisting of body air blower 2E of embodiment 9 and air blowing control device 403A which is a modified example of air blowing control device 403 of embodiment 4.

[0242] The body blower 2E has a flange corresponding to the flange 26 of the mounting side connection part 25 of the body blower 2 formed at the opening 921 of the airflow direction changing member 900. The opening 921 of the airflow direction changing member 900 is formed in a manner that allows it to be attached to and detached from the connection part of the airflow control device, as shown in Fig. 55. Specifically, the airflow control device 403A(3) has a groove in the connection part like the connection part 110 of the airflow control device 103(3) according to embodiment 1, instead of the fixing part 450 of the airflow control device 403.

[0243] In the body blower with airflow control device 1Xu(1X), the airflow control device 403A(3) and the body blower 2E are attached in a detachable manner by fitting a groove at the connection part formed in the airflow control device 403(3) into a flange provided at the opening 921 in the body blower 2E.

As shown in Fig. 56, the body blower with an air blowing control device 1Xv (1X) comprises the body blower 2E of embodiment 9 and the air blowing control device 303 (3) of embodiment 3.

[0247] Like the body blower device with airflow control device 1Xu(1X), the body blower device with airflow control device 1Xv(1X) also has an opening 921 of the airflow direction changing member 900 with a flange corresponding to the flange 26 of the mounting side connection part 25 of the body blower device 2A. In the body blower device with airflow control device 1Xv(1X), the airflow control device 303(3) is attached in a detachable manner to the body blower device 2E.

[0248] <Embodiment 12> Next, an embodiment of a body air blowing device with an air blowing control device according to the present disclosure will be described as embodiment 12. The body air blowing device with an air blowing control device according to the present disclosure comprises an air blowing control device according to the present disclosure and a body air blowing device. In the body air blowing device with an air blowing control device according to embodiment 12, as described above, the air blowing control device according to embodiments 1 to 4 corresponds to the air blowing control device according to the present disclosure.

[0249] That is, the body blower 2 etc. (2) configured as the body blower with an airflow control device according to embodiment 12 includes a housing 10 as described in detail in embodiments 1 to 5. The housing 10 is made up of an outer housing portion 11 and an inner housing portion 12A (12) which are separate bodies. Alternatively, the housing 10 is made up of an outer housing portion 11 and an inner housing portion 12B (12) which are separate bodies. Alternatively, the housing 10 is made up of an outer housing portion 11 and an inner housing portion 12C (12) which are separate bodies. Alternatively, the housing 10 is made up of an outer housing portion 11 and an inner housing portion 12D (12) which are separate bodies.

[0250] On the other hand, the body blower 2 includes a Peltier element unit 30 including a Peltier element 31, a heat sink 32 including an air-blow side heat sink 32A and an exhaust side heat sink 32B, and a blower fan 35. The body blower 2 and the like are worn on the body when in use, and blow temperature-adjusted air FL from the air outlet 23 toward the body. The air blower control devices according to the first to fourth embodiments are worn on such a body blower 2.

[0251] A specific description will be given below. The body air blower with air blowing control device according to embodiment 12 is, as example 1, the first aspect of the device in embodiment 1, which is composed of body air blower 2A(2) and air blowing control device 103A(3) as shown in Figs. 1 and 9 etc.

[0252] In addition, the body air blowing device with air blowing control device of embodiment 12 is, as Example 2, a second type of device in embodiment 1, consisting of a body air blowing device 2A(2) and an air blowing control device 103B(3), as shown in Figures 1 and 13, etc.

[0253] In addition, the body air blowing device with air blowing control device of embodiment 12 is a third type of device in embodiment 2 as Example 3, which is composed of a body air blowing device 2A(2) and an air blowing control device 203A(3) as shown in Figures 1 and 14, etc.

[0254] In addition, the body air blower with air blowing control device of embodiment 12 is a fourth type of device in embodiment 2 as Example 4, which is composed of a body air blower 2A(2) and an air blowing control device 203B(3) as shown in Figures 1 and 18, etc.

[0255] In addition, the body air blower with air blowing control device of embodiment 12 is a fifth aspect of the device in embodiment 3 as Example 5, which is composed of a body air blower 2B(2) and an air blowing control device 303(3), as shown in Figures 23 and 24, etc.

[0256] In addition, the body air blower with air blowing control device of embodiment 12 is, as Example 6, a sixth aspect of the device in embodiment 4, consisting of a body air blower 2C(2) and an air blowing control device 403(3), as shown in Figures 28 and 29, etc.

[0257] Next, the operation and effect of the airflow control device, the body airflow device, and the body airflow device with airflow control device according to the present embodiment will be described.

[0258] The airflow control device 3 (103A, 103B, 103A, 103B, 303, 403) according to the present embodiments 1 to 8 and 10 to 12 includes a housing 10 having an outer housing part 11 in which an air intake port 21 and an air exhaust port 22 are formed, an inner housing part 12 (12A, 12B, 12C, 12D) connected to the outer housing part 11 in an opposed arrangement and butted against each other, and the housing 10 has an airflow port 23 arranged therein, a Peltier element 31 arranged in the housing 10, and an airflow-side heat sink 32A (a cooling fin or a heat dissipation fin) formed on one surface 31a of the Peltier element 31. The device is equipped with a heat sink 32A (either heat dissipation fins or cooling fins) formed on the surface 31b opposite to the surface 31a, and an air blower fan 35 that introduces air from the intake port 21 and blows it to the air blower side heat sink 32A and the exhaust side heat sink 32B. The device is worn on the body of a user HM and is worn on the body of the air blower 2A, 2B, 2C, 2D (2) that blows out temperature-adjusted air FL, which is either cold air CF that has passed through the air blower side heat sink 32A or hot air HF that has passed through the heat dissipation fins, from the air blower port 23. The air blower control device 3 is attached to the air blower 2 for the body to control the flow of the temperature-adjusted air FL. The air flow control device 3 comprises a hollow flow path FP through which the temperature-adjusted air FL can flow, a connection portion 110, 210, 310, 410 formed so as to be detachable from the air outlet 23 by at least one fixing means of fitting, fastening, and engagement, an introduction portion 120, 220, 320, 420 which takes the temperature-adjusted air FL supplied from the air outlet 23 into the flow path FP from the inlet 121 when the connection portion 110, 210, 310, 410 is attached to the housing 10, and a blowing portion 130, 230, 330, 430 which extends from the introduction portion 120, 220, 320, 420 to the outlet 131 of the flow path FP. Of the flow paths FP, the outlet side flow path FPe passing through the blowing sections 130, 230, 330, 430 is characterized in that the cross-sectional area S1 on the outlet 131 side is equal to or smaller than the introduction sections 120, 220, 320, 420 side.

[0259] Due to this feature, the temperature-adjusted air FL generated by the body air blower 2 can be efficiently blown by the air blower control device 3 over a wide area and along the body surface toward the desired body part of the user HM.

[0260] In particular, for example, when the air supply control devices 3 are configured in a plurality of types, such as air supply control devices 103A, 103B, 203A, 203B, and 303, with the specifications of connection parts 110, 210, and 310 being common, but with the rest being different in structure, shape, and other specifications, the plurality of types of air supply control devices 3 are grouped together and can all be attached to the body air supply device 2. Therefore, the plurality of types of air supply control devices 3 can be attached to the same body air supply device 2 with compatibility.

[0261] Therefore, the user HM can select an airflow control device that meets his / her needs from among the multiple types of airflow control devices 103A, 103B, 203A, 203B, 303(3) and attach it to the personal airflow device 2 that he / she owns.

[0262] Furthermore, even if the part of the body to which the user HM wants to receive the temperature-adjusted air FL changes, the user can change the airflow control device from the multiple types of airflow control devices 103A, 103B, 203A, 203B, 303(3) to an airflow control device that is compatible with the part of the body to which the user wants to receive the temperature-adjusted air FL, for example by changing the airflow control device 103A to the airflow control device 203A. Thus, the airflow control device 3 can widely meet the needs of the user HM.

[0263] In addition, the air flow control device 3 of the present embodiments 1 to 4 is characterized in that the introduction sections 120, 220, 320, 420 are formed in a shape that narrows on the outlet 131, 231, 331, 431 side so that the cross-sectional area S2 on the outlet 131, 231, 331, 431 side is smaller than that on the introduction section 120, 220, 320, 420 side.

[0264] Due to this feature, the temperature-adjusted air FL supplied from the body blower 2 is blown out from the outlet 131, 231, 331, 431 at a higher wind speed, so that the air can be blown over a wider area along the body surface of the user HM, such as the hands and legs, upper body, neck, and head. Moreover, the airflow control device 3 has a shape narrower on the outlet 131, 231, 331, 431 side. Therefore, the blowing section 130, 230, 330, 430 can be easily arranged in a narrow space, such as a narrow space between the body of the user HM and the clothes he or she is wearing, or a narrow space between the head of the user HM wearing a helmet and the shell of the helmet.

[0265] Also The air flow control device 303(3) according to the third embodiment is characterized in that in the inlet section 320, a flow guide section 325 is formed in the flow path FP to guide the flow of the temperature-adjusted air FL taken in toward the outlet section 330.

[0266] This feature makes it possible to suppress the generation of excessive turbulence due to a decrease in flow speed and a pressure loss in the temperature-adjusted air FL when the temperature-adjusted air FL taken in by the introduction section 320 flows along the inner wall of the flow path FP to the blowing section 330. Therefore, the temperature-adjusted air FL is blown out to the outside in a state close to laminar flow, suppressing a decrease in wind speed from the introduction section 320 to the outlet 331 of the blowing section 330 within the flow path FP.

[0267] Moreover, in the air supply control devices 103, 203, 303(3) of the present embodiments 1 to 3, the connection parts 110, 210, 310 are made of a flexible material, and are characterized in that they can be connected to the body air supply devices 2A, 2B(2) by elastically deforming the connection parts 110, 210, 310 and attaching them to the air supply opening 23.

[0268] This feature allows the airflow control device 3 and the body air blower 2 to be constructed with simple structures for connection and disconnection between the body air blower 2 and the airflow control device 3, making them inexpensive to manufacture. Moreover, the user HM can easily connect and disconnect the airflow control device 3 and the body air blower 2.

[0269] In particular, when the connection parts 110, 210, 310 are made of, for example, silicone rubber, rubber, etc., when the flange 26 of the mounting side connection part 25 of the body blower 2 is connected by fitting with the groove 111 of the connection part 110, etc., the airtightness of the joint between the air supply control device 3 and the body blower 2 is improved. Therefore, the temperature-adjusted air FL supplied from the body blower 2 can be sent to the introduction part 120 of the air supply control device 3, etc., without leaking from the joint.

[0270] Furthermore, the airflow control device 3 of this embodiment 4 is characterized in that, when connecting to the body air blower 2C(2), a fixing portion 450 is formed to fix the connection portion 410 to the air outlet 23.

[0271] Due to this feature, the body air blower 2C(2) can be connected to and disconnected from the air blow control device 3 at the fixing part 450, so that it can be used in cases where the air blow control device 3 is required and cases where it is not required.

[0272] In particular, when the user HM is a worker working at a site where the work involves danger, such as a civil engineering construction site or a factory plant facility, while the user HM is working while wearing the body air blower 2C(2) to which the air blowing control device 403(3) is attached, the external forces and impacts accompanying the work movements may have a significant effect on the air blower control device 403(3) and the body air blower 2C(2).

[0273] On the other hand, the airflow control device 3 is connected to the body air blower 2C(2) at the fastening part 450 by screw fastening, and the airflow control device 403(3) and the body air blower 2C(2) are firmly connected. Therefore, even in such a case, the airflow control device 403(3) is prevented from coming off the body air blower 2C(2) due to external forces or impacts associated with work movements.

[0274] Also, the airflow control devices 103A, 203B(3) according to the first and second embodiments are characterized in that they include flaps 140, 240 that change the direction of the temperature-adjusted airflow FL circulating through the circulation path FP.

[0275] Due to this feature, in the case of airflow control device 103A(3), even when the user HM has positioned outlet 131 of blowing section 130 toward a desired part of the body that wants to receive temperature-adjusted air FL, the user HM can select to send additional temperature-adjusted air FL to another part of the body that wants to receive temperature-adjusted air FL at the same time. The same is true for airflow control device 203B(3).

[0276] That is, when the flaps 140, etc. are opened, the temperature-adjusted air FL that flows into the inlets 121, etc. is split into a main flow to the outside from the outlets 131, etc., and a branch flow to the outside from the openings 142, etc. that are oriented in a different direction from the outlets 131, etc., and is then blown out. Conversely, when the flaps 140, etc. are closed, the temperature-adjusted air FL is blown out to the outside only as a main flow from the outlets 131, etc.

[0277] Furthermore, in the air flow control device 3 of the present embodiments 2 and 3, the air flow control device 203, 303 includes at least two blowing sections 230, 330, and the first blowing section 230a and the second blowing section 230b, and the first blowing section 330a and the second blowing section 330b are formed in a manner in which they branch out and bend in different directions at the introduction section 220, 320, respectively, and the first blowing section 230a and the second blowing section 230b are arranged on opposite sides to each other in the Y-axis direction, or are arranged in an approximately V-shape.

[0278] Due to this feature, the airflow control device 203, 303 can blow air over a wider area to the body parts of the user HM that wish to receive the temperature-adjusted airflow FL. Moreover, the temperature-adjusted airflow FL spreads over a wider area from both the first blowing section 230a and the second blowing section 230b of the blowing section and is blown along the body surface without hitting the body of the user HM directly, so that the user HM can feel comfortable.

[0279] Similarly, the temperature-adjusted air FL spreads over a wide area from both the first blowing section 330a and the second blowing section 330b without hitting the user HM's body directly, and is blown along the surface of the body, allowing the user HM to feel comfortable.

[0280] In addition, the air flow control device 3 of this embodiment 4 is an air flow control device 403 including one blowing section 430, and is characterized in that the blowing section 430 is formed in a manner that is bent in an approximately J-shape toward one side in the H-axis direction, with the introduction section 410 as the boundary.

[0281] Due to this feature, the outlet 431 of the blowing section 430 can be positioned so as not to face the body of the user HM, so that the temperature-adjusted air FL supplied from the body blower 2 can be blown locally along the surface of the body toward the part of the user HM's body that wishes to receive the air, without hitting the user HM's body directly.

[0282] That is, when the temperature-adjusted air FL is cold air CF, the user HM is not excessively cooled by the cold air CF (temperature-adjusted air FL) and does not feel uncomfortable. Also, when the temperature-adjusted air FL is hot air HF, the user HM can be prevented from being excessively heated by the hot air HF (temperature-adjusted air FL).

[0283] Moreover, in the air blowing control device 403(3) of this embodiment 4, the blowing section 430 has a wall member 432 that surrounds the circulation path FP and a protrusion 433 that protrudes from the wall member 432, and when the connection section 410 is attached to the body blowing device 2, the protrusion 433 is formed in a portion of the wall member 432 that faces the inner housing section 12(12) of the body blowing device 2C(2).

[0284] Due to this feature, the plurality of protrusions 433 function as ribs for reinforcing the wall member 432. Due to the plurality of protrusions 433, the blowing section 430 can be configured with higher rigidity.

[0285] In particular, when the user HM is a worker working at a site where the work is dangerous, such as a civil engineering construction site or a factory plant facility, the personal air blower 2C(2) equipped with the air blower control device 403(3) may be attached to the work clothes. In such a case, the air blower control device 403(3) is highly durable against external shocks caused by the work movements during the work, and is therefore unlikely to be damaged.

[0286] In addition, the body air blower 1 with an air blowing control device according to the present embodiment 12 includes a housing 10 having an outer housing part 11 in which an air intake port 21 and an air exhaust port 22 are formed, an inner housing part 12 (12A, 12B, 12C, 12D) connected to the outer housing part 11 in an opposing arrangement and butted together, and in which an air blowing port 23 is arranged, a Peltier element 31 arranged within the housing 10, an air blowing side heat sink 32A (either a cooling fin or a heat dissipation fin) formed on one surface 31a of the Peltier element 31, and an air exhaust side heat sink 32B (heat dissipation fin) formed on the other surface 31b opposite to the one surface 31a. The body blower 2 (2A, 2B, 2C, 2D) is equipped with a fan 35 that draws air from the intake port 21 and blows it to the exhaust side heat sink 32A and the exhaust side heat sink 32B, and is attached to the body of a user HM. The body blower 2 (2A, 2B, 2C, 2D) is equipped with a fan 35 that draws air from the intake port 21 and blows it to the exhaust side heat sink 32B and the air blower 23. The body blower 2 (2A, 2B, 2C, 2D) is equipped with a fan 35 that draws air from the intake port 21 and blows it to the exhaust side heat sink 32A and the exhaust side heat sink 32B, and the fan 35 is attached to the body of a user HM and blows out temperature-adjusted air FL, which is either cold air CF that has passed through the exhaust side heat sink 32A or hot air HF that has passed through the heat dissipation fins, and the air blower control device 3 (103A, 103B, 103A, 103B, 303, 403) is detachably attached to the housing 10 of the body blower 2.

[0287] Due to this feature, the temperature-adjusted air FL is blown by the airflow control device 3 along the body surface without hitting the user HM directly, allowing the user HM to feel comfortable. In addition, the airflow control device 3 can efficiently blow air along the body surface over a wide area toward the part of the user HM's body that wishes to receive the temperature-adjusted air FL.

[0288] Moreover, in the air blower for body 2E according to the ninth embodiment, the housing 810 has an outer housing part 811 in which an air intake port 821 and an exhaust port 822 are formed, an inner housing part 812 which is connected by being butted against the outer housing part 811 in an opposing arrangement, and in which an air blowing port 823 is arranged, a Peltier element 31 arranged within the housing 810, an air blowing side heat sink 32A (either cooling fins or heat dissipation fins) formed on one surface 31a of the Peltier element 31, an exhaust side heat sink 32B (either heat dissipation fins or cooling fins) formed on the other surface 31b opposite to the one surface 31a, and an air blowing fan 35 which introduces air from the air intake port 821 and blows air to the air blowing side heat sink 32A and the exhaust side heat sink 32B. When the air blower for body 2E according to the ninth embodiment is worn on the body of a user HM, the housing 810 is provided with a cooling fan 35 which blows air through the air blowing side heat sink 32A. In a body blower device in which temperature-regulated air FL, which is either warm air HF that has passed through a heat dissipation fin or warm air HF that has passed through a heat dissipation fin, is blown out from a blowing area Q, the device is provided with an air direction changing member 900 in which an opening 921 formed in a manner that allows the temperature-regulated air FL to flow to the outside and a blocking portion 922 that blocks the flow of the temperature-regulated air FL to the outside are arranged in different directions, the housing 810 forming a cover of the body blower device 2E includes an enclosing gap 815 in which a portion of a space 810S including the blowing area Q is opened, the enclosing gap 815 being provided at a connection point 814 between a first side portion 813a of the housing 810 and a second side portion 813b adjacent to the first side portion 813a in a direction different from that of the first side portion 813a, the air direction changing member 900 forming part of the housing and being attached to the enclosing gap 815.

[0289] With this feature, the body blower 2E can freely select the direction of the temperature-adjusted air FL to be blown by the air direction changing member 900 according to the purpose of the user HM. Therefore, when the user HM uses the body blower 2E that he / she owns, the range of options for the installation mode of the body blower 2E is wider, and the degree of freedom in the mode of use of the body blower 2E is high.

[0290] Specifically, the body blower 2E can be flexibly adapted to any carrying method, such as when the user HM carries the body blower 2E in a clothing pocket, when the body blower 2E is hung from the upper body, when the body blower 2E is fixed to a trouser belt or a tool, by adjusting the direction of the temperature-adjusted air FL suitable for the carrying method using the air direction changing member 900. Therefore, the body blower 2E is easy to use.

[0291] In addition, the body air blower 1X (1Xu1Xv) with an air blowing control device according to the present embodiments 10 and 11 includes a housing 810 having an outer housing part 811 in which an air intake port 821 and an exhaust port 822 are formed, an inner housing part 812 connected to the outer housing part 811 in an opposing arrangement and having an air blowing port 823 arranged therein, a Peltier element 31 arranged within the housing 810, an air blowing side heat sink 32A (either cooling fins or heat dissipation fins) formed on one surface 31a of the Peltier element 31, an exhaust side heat sink 32B (either heat dissipation fins or cooling fins) formed on the other surface 31b opposite to the one surface 31a, and an air blower fan 35 that introduces air from the air intake port 821 and blows air to the air blowing side heat sink 32A and the exhaust side heat sink 32B, and is attached to the body of a user HM, and a temperature of either cold air CF that has passed through the air blowing side heat sink 32A or hot air HF that has passed through the heat dissipation fins is measured. The body blower 2E includes an airflow direction changing member 900 in which an opening 921 formed in a manner that allows the temperature-conditioned air FL to circulate to the outside and a blocking portion 922 that blocks the flow of the temperature-conditioned air FL to the outside are arranged in different directions, and the housing 810 that forms the cover of the body blower 2E includes an enclosing gap 815 in which a part of a space 810S including the airflow area Q is opened, and the enclosing gap 815 is a part of the housing 810 that is formed in a manner that allows the temperature-conditioned air FL to circulate to the outside. The airflow direction changing member 900 is provided at a connection point 814 between a first side portion 813a and a second side portion 813b adjacent to the first side portion 813a in a different direction from the first side portion 813a, and the airflow direction changing member 900 forms part of the housing and is intended for a body air blowing device 2E that is attached to the surrounding gap 815, and the airflow control device 3 (103A, 103B, 103A, 103B, 303, 403) is removably attached to an opening 921 of the airflow direction changing member 900.

[0292] With this feature, the device body of the body blower 1X with airflow control device is the body blower 2E, and the body blower 2E can freely select the direction of the temperature-adjusted air FL to be blown by the air direction changing member 900 according to the purpose of the user HM. Therefore, when the user HM uses the body blower 2E that he or she owns, the range of options for the installation mode of the body blower 2E is wider, and the degree of freedom in the mode of use of the body blower 2E is high.

[0293] This allows the user HM to use the body air blower 1X with air blowing control device in a variety of ways, such as by placing it in a clothing pocket, attaching it to the belt of work trousers, or attaching it to light clothing while jogging.

[0294] In addition, even if the user HM uses the body air blower device 1X with air blowing control device in various ways, the user HM can feel comfortable because the temperature-adjusted air FL is blown along the body surface by the air blowing control device 3 without hitting the user HM's body directly. Furthermore, the air blowing control device 3 can efficiently blow air along the body surface over a wide area toward the part of the user HM's body that wants to receive the temperature-adjusted air FL.

[0295] Furthermore, in the body air blower 1X with air blowing control device of this embodiment 9, the air direction changing member 900 is characterized in that it is formed in a manner that allows it to be reversibly attached to the surrounding missing portion 815 in either arrangement form, that is, a first arrangement form in which the opening 921 is arranged on the first side 813a side and the blocking portion 922 is arranged on the second side 813b side, and a second arrangement form in which the opening 921 is arranged on the second side 813b side and the blocking portion 922 is arranged on the first side 813a side.

[0296] Due to this feature, the body air blower 1 with an airflow control device can change the direction of the opening 921 from which the temperature-conditioned air FL is blown out according to the position of the body part of the user HM that wishes to receive the temperature-conditioned air FL.

[0297] Furthermore, in the body blower 1 with airflow control device of this embodiment 12, the inner casing part 12 (12A, 12B, 12C, 12D) includes a fixed part 50 formed so as to be able to engage with a fixing part 450 etc. on the airflow control device 3, the housing 10 is characterized in that the inner casing part 12 and the outer casing part 11 are each constructed as separate bodies, and by engaging the fixing part 450 etc. of the airflow control device 3 with the fixed part 50 of the inner casing part 12, the air outlet 23 of the body blower 2 which constitutes the main body of the body blower with airflow control device is connected to the connection parts 110, 210, 310, 410 of the airflow control device 3.

[0298] Due to this feature, in the body air blower 1 with air blowing control device, an air blowing control device selected as needed from multiple types of air blowing control devices 103A, 103B, 203A, 203B, 303, 403(3) can be attached to the air blowing port 23 of the body air blower 2.

[0299] In particular, like the airflow control device 103A etc. (airflow control devices 103A, 103B, 203A, 203B, 303), the airflow control device 103A etc. is connected to the airflow port 23 of the body airflow device 2A(2) by a fixing means formed by fitting the groove 111 of the elastically deformed connection part 110 with the flange 26 of the mounting side connection part 25 of the body airflow device 2A. On the other hand, the airflow control device 403 is connected and attached to the body airflow device 2C(2) by a fixing means formed by the engagement of the engagement piece 451 of the fixing part 450 with the engagement groove 51 of the fixed part 50 of the inner casing part 12C, and by a fixing means formed by screwing the fixing part 450 and the fixed part 50 together.

[0300] Even when the fixing means between the airflow control device 3 and the body blower 2 are different, such as airflow control device 103A which uses fitting as the fixing means and airflow control device 403 which uses engagement and screw fastening as the fixing means, the outer casing part 11 in the housing 10 can be made common between the body blower 2A(2) and the body blower 2C(2).

[0301] Therefore, in the housing 10, by simply replacing the inner casing part that joins the outer casing part 11 with the inner casing part 12 that corresponds to the fixing means of the air blowing control device 3 to be attached, such as by replacing the inner casing part 12A(12) on the side of the body blower 2A(2) with the inner casing part 12C(12) of the body blower 2C(2), the user HM can select the air blowing control device that suits his or her needs from among the multiple types of air blowing control devices 103A, 103B, 103A, 103B, 303(3) and attach it to the body blower 2 he or she owns.

[0302] That is, even if the part of the body to which the user HM wants to receive the temperature-adjusted air FL changes, the user HM can change the airflow control device from the multiple types of airflow control devices 103A, 103B, 103A, 103B, 303(3) to an airflow control device that is compatible with the part of the body to which the user HM wants to receive the temperature-adjusted air FL, as necessary. Therefore, the airflow control device 3 can widely meet the needs of the user HM.

[0303] Furthermore, in the body air blower 1, 1X with an airflow control device according to the present embodiments 10, 11, the opening 921 of the airflow direction changing member 900 is formed in a manner that allows it to be attached and detached to the connection part 110, 210, 310, 410 of the airflow control device 3.

[0304] Due to this feature, the user HM can select between the first and second arrangements for the arrangement of the air direction changing member 900 relative to the surrounding gap 815 each time he or she uses the body air blower 1 with air blowing control device he or she owns, depending on the purpose of use, and therefore the direction of the temperature-adjusted air FL to be blown can be easily changed.

[0305] The body air blower 1A(1) with an air blowing control device according to the fifth embodiment is characterized in that it includes a cap body attachment part 550 that can be attached to a cap body 571 of a helmet 570.

[0306] This feature allows the user HM to attach the body air blower with air blowing control device 1A integrally with the helmet 570.

[0307] Moreover, in the body air blowing device 1A(1) with an air blowing control device according to this embodiment 5, the inner casing part 12 is an inner casing part 12D including a cap body attachment part 550 and a holding guide part 510 formed so as to be detachable, and the housing 10 is characterized in that it is composed of an outer casing part 11 and the inner casing part 12D.

[0308] Due to this feature, the body blower device 1A(1) with an airflow control device can be used when not attached to the helmet 570 and when attached to the helmet 570. When the body blower device 1A with an airflow control device is attached to the helmet 570, the temperature-adjusted air FL is mainly cool air CF.

[0309] When a user HM wears a helmet 570 equipped with a body blower 1A with an airflow control device that blows out cool air CF, in the helmet interior space 570S, the body blower 1A with an airflow control device can blow temperature-adjusted air FL toward the top of the head of the user HM wearing the helmet 570 and the surrounding area. This allows the user HM wearing the helmet 570 to feel comfortable.

[0310] That is, in dangerous work sites such as civil engineering sites and factory plant facilities, workers generally wear heavy work clothes and helmets to protect themselves from danger. When such work sites are exposed to the scorching sun and are subject to humid weather conditions, workers working at the site become stuffy around the neck and above the head inside the helmet because there is almost no ventilation. As a result, the workers feel uncomfortable due to this stuffiness. This type of phenomenon occurs frequently.

[0311] Therefore, when a user HM uses a helmet 570 equipped with a body air blower 1A(1) with an air blowing control device, the user HM can receive cool air CF (temperature-adjusted air FL) in the stuffy internal space 570S of the helmet even while wearing work clothes and the helmet 570.

[0312] In particular, as shown in Figures 34, 35 and 37, in the stuffy internal helmet space 570S, cool air CF (temperature-adjusted air FL) is blown from outlet 131 of blowing section 130 and opening 142 when flap 140 is opened, even to different positions such as around the neck, in addition to above and around the head. Therefore, a user HM wearing helmet 570 can obtain comfort from the cool air CF (temperature-adjusted air FL) blown out from body blower 1A with airflow control device. Body blower 1A with airflow control device can of course change temperature-adjusted air FL to hot air HF.

[0313] The body air blower with air blowing control device (1), 1Xu (1X) according to the sixth and tenth embodiments is characterized in that it has a clothing attachment part 60 that can be attached to clothing 600.

[0314] This feature allows the user HM to attach the body air blower 1 with the air blowing control tool integrally with the clothing 600 that he or she is wearing.

[0315] Furthermore, in the body blower device with airflow control device 1C(1), 1Xu(1X) of the present embodiments 6 and 10, the clothing attachment portion 60 is characterized in that it is a gap formed between the body blower device 2C, which constitutes the main body of the body blower device with airflow control device, and the airflow control device 403.

[0316] Due to this feature, the user HM can easily attach and wear the body air blower with air blowing control device 1C to the clothing 600, etc., by simply inserting the collar 610 and sleeves of the clothing 600 to be worn, as well as the placket, cuffs, collar, and lower edges of the front and back body of a shirt, into the clothing attachment part 60.

[0317] The present disclosure has been described above in accordance with the embodiments 1 to 12, but the present invention is not limited to the above embodiments 1 to 12, and can be modified and applied as appropriate without departing from the spirit of the present invention.

[0318] For example, in the air flow control device according to the present disclosure, the tip portion of the blowing portion including the outlet port may be formed to be expandable and contractible, for example, by a bellows structure or the like.

[0319] In addition, in the air flow control device according to the present disclosure, the entire blowing section or the tip portion of the blowing section including the outlet may be made of a flexible material and configured in such a manner that the direction in which the air is blown out after temperature adjustment can be freely changed.

[0320] In addition, in the eighth embodiment, as shown in FIG. 46, pockets 620 are arranged on the garment 600B at positions near the back and sides, and each pocket 620 contains a body air blower with an air blowing control device 1C(1). However, FIG. 46 is illustrated solely for ease of viewing.

[0321] Therefore, the position of the body air blower device 1E with an air blowing control device to be placed on clothing is not exactly as shown in FIG. 46, and is not limited to the position shown in FIG.

[0322] In other words, the body air blower 1 with air blowing control device, which is worn in the pocket, is placed in a position that takes into consideration the ease of movement of the person wearing the garment 600B, with particular focus on the neck, armpits, and sides, which tend to sweat a lot, and is positioned to cool the blood in the arteries that pass near these areas and to cool areas of the body that are prone to sweating.
