Description

Airflow control device, body air blower, and body air blower with airflow control device

[0001] The present disclosure relates to an airflow control device attached to an air outlet of a body air blower used by being worn on the body, for controlling the flow of the temperature-adjusted air blown out from the air outlet. The present disclosure also relates to a body air blower and a body air blower with an airflow control device including such an airflow control device.

[0002] In recent years, there are many sweltering days that are uncomfortable for people throughout the year. On sweltering days, as a measure to prevent heat stroke, in addition to taking small sips of water, the use of appropriate air conditioning devices is encouraged.

[0003] However, due to reasons such as the absence of air conditioning equipment or insufficient cooling effect, workers working outdoors in sweltering heat or workers working in a stuffy indoor environment, and people enjoying recreation, sports, watching games, etc. under the scorching sun cannot cool off with an air conditioning device.

[0004] Therefore, in recent years, clothing with an air conditioning function, portable air conditioning devices, etc. have been rapidly spreading mainly targeting people seeking避暑 in such situations. Among such air conditioning devices, an air blower using a Peltier element has also been developed. An example of such an air blower is disclosed in Patent Documents 1 and 2.

[0005] Patent Document 1 discloses a cooling device for clothing including a housing, a Peltier element inside the housing, cooling fins formed on one surface of the Peltier element, heat dissipation fins formed on the other surface opposite to the one surface, a blower fan for sending 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 the cold air that has passed through the cooling fins, and a heat dissipation outlet for exhausting the hot air that has passed through the heat dissipation fins.

[0006] An air intake is formed in the housing, and the cold air outlet and the heat dissipation outlet are formed in opposite directions. In Patent Document 1, the cooling device for clothing is worn on the user's clothing by arranging and fixing a flange provided at the cold air outlet on the inner and outer peripheral surfaces of an opening provided in the clothing.

[0007] Patent Document 2 describes a fan unit that attaches to and secures to the belt of trousers and delivers temperature-controlled air to the user's back. Patent Document 2 comprises a Peltier element that adjusts the temperature of the air blown from a fan, a casing that houses the fan and the Peltier element, and an air supply nozzle. The air supply nozzle is attached to an air inlet formed in the casing.

[0008] Patent Document 2 describes an air intake nozzle that is cylindrical and bent in a roughly Z-shape to prevent the temperature-controlled air from blowing directly onto the user's back or other body parts from the air intake. This prevents the user from overcooling or overheating their back or other body parts with the temperature-controlled air.

[0009] Japanese Patent Publication No. 7290237, Japanese Unexamined Patent Publication No. 2023-93944

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

[0011] In Patent Document 1, the garment cooling device is attached to the garment with a cold air vent fixed to the opening of the garment to be worn. In this case, the cold air vent faces the user's body. Therefore, the cold air blown out from the vent directly hits the user's body. Consequently, only the parts of the user's body that receive the cold air directly are cooled by the cold air, while other parts of the body are not exposed to the cold air at all.

[0012] Therefore, clothing cooling devices cannot cool the user's body over a wide area with the cold air blown from the vents. In addition, clothing cooling devices may overcool specific parts of the user's body that are exposed to the cold air blown from the vents.

[0013] By the way, in places where work is inherently dangerous, such as civil engineering sites or factory plant facilities, workers generally wear heavy work clothes and helmets to protect themselves from danger. When such sites are exposed to the scorching sun and humid weather conditions, the necks of workers and the tops of their heads inside their helmets become stuffy due to the lack of ventilation. As a result, workers feel uncomfortable due to this stuffiness.

[0014] Such incidents occur frequently. Therefore, workers are looking for a ventilation device that can supply cool air to areas that are sweating while wearing work clothes and helmets. In particular, at the aforementioned work sites, many workers have requested a single ventilation device that can be used universally to supply cool air to sweaty areas in a manner that is appropriate to the location of the sweaty area, even if the sweaty area is in a different location on the body, such as the nape of the neck or the top of the head inside the helmet.

[0015] Patent Document 2 describes a system in which a blower unit is attached to the user's trouser belt, and temperature-controlled air is blown only towards the spinal area of ​​the back through an air intake nozzle attached to the air intake. Therefore, Patent Document 2 has the problem that it is not possible to universally blow temperature-controlled air to different parts of the body, such as when blowing air over the head inside a helmet, using a single blower unit.

[0016] This disclosure was made to solve the above-mentioned problems and aims to provide a fan control device, a body fan, and a body fan equipped with this fan control device, which are user-friendly and can efficiently deliver temperature-controlled air supplied from a fan to the desired part of the body.

[0017] (1) To solve the above problems, an air blower control device according to one aspect of the present disclosure comprises a housing having an outer housing portion having an intake port and an exhaust port formed therein, and an inner housing portion abutted and connected to the outer housing portion in a facing position, and having an air blower port, a Peltier element disposed within the housing, a cooling fin formed on one surface of the Peltier element, a heat dissipation fin formed on the other surface opposite to the one surface, and a blower fan that introduces air from the intake port and sends air to the cooling fin and the heat dissipation fin, and is a body blower device that is worn on the body and blows out temperature-controlled air, which is either cold air that has passed through the cooling fin or warm air that has passed through the heat dissipation fin, from the air blower port. The air blower control device, which is attached to the body blower and controls the flow of the temperature-controlled air, comprises: a hollow flow path through which the temperature-controlled air can flow; a connecting portion formed to be detachably attached to the air outlet by at least one fixing means among fitting, fastening, and engaging; an introduction portion that takes in the temperature-controlled air supplied from the air outlet into the flow path from the inlet when the connecting portion is attached to the housing; and a blowing portion that extends from the introduction portion to the outlet of the flow path, wherein in the outlet-side flow path that passes through the blowing portion, the cross-sectional area on the outlet side is the same size as or smaller than that on the introduction side.

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

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

[0020] According to this embodiment, since the air blower control device has a shape that narrows at the outlet side, the blower can be easily placed in narrow spaces, such as the narrow space between the user's body and the clothing being worn, or the narrow space between the user's head and the helmet shell when wearing a helmet.

[0021] (3) In the embodiment described in (1) or (2) above, it is preferable that the introduction section has a flow guide section formed in the flow path that guides the temperature-controlled airflow taken in toward the discharge section.

[0022] According to this embodiment, when the temperature-controlled air taken into the inlet flows along the inner wall of the flow path to the outlet, it is possible to suppress the generation of excessive turbulence caused by a decrease in flow velocity and pressure loss in the flowing temperature-controlled air.

[0023] (4) In the embodiment described in any one of (1) to (3) above, it is preferable that the connecting portion is made of a flexible material and that the air blower control device can be connected to the body blower by elastically deforming the connecting portion and attaching it to the air outlet.

[0024] According to this embodiment, when connecting and disconnecting the body ventilation device and the ventilation control device, both the ventilation control device and the body ventilation device can be constructed with simple structures, thus enabling inexpensive manufacturing. Moreover, the user can easily attach and detach the ventilation control device and the body ventilation device.

[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 air blower control device and the body blower is improved. As a result, the temperature-controlled air supplied from the body blower can be delivered to the inlet of the air blower control device while preventing leakage at the joint.

[0026] (5) In the embodiment described in any one of (1) to (4) above, it is preferable that a fixing portion is formed in the air outlet for fixing the connection portion when connecting to the body ventilation device.

[0027] According to this embodiment, the body ventilation device can be connected to and disconnected from the ventilation control device at the fixing part, so that it can be used differently depending on whether the ventilation control device is needed or not.

[0028] Furthermore, if the air blower control device is connected to the body blower device at a fixed part by a fixing means such as screw fastening, the air blower control device can be firmly connected to the body blower device. Therefore, even if a large external force or impact acts on the connected air blower control device and body blower device during use, the air blower control device is prevented from becoming detached from the body blower device due to such external forces or impacts.

[0029] (6) In any one of the embodiments described in (1) to (5) above, it is preferable to provide a flap that changes the direction of the temperature-controlled air flowing through the flow path.

[0030] According to this embodiment, even when the user positions the outlet of the air outlet towards a desired part of the body that they wish to receive the temperature-controlled air, it is possible to additionally deliver the temperature-controlled air to another part of the body that also wishes to receive the temperature-controlled air by opening the flap.

[0031] (7) In the embodiment described in any one of (1) to (6) above, in the first air blower control device which includes at least two blowing sections, it is preferable that each blowing section is formed in such a manner that it branches and bends in different directions with respect to the introduction section, that the two blowing sections are arranged on opposite sides of each other with respect to one direction, or that they are arranged in a substantially V-shape.

[0032] According to this embodiment, the airflow control device can deliver air over a wider area to the body parts of the user that wish to receive the temperature-controlled airflow. Moreover, since the temperature-controlled airflow does not directly hit the user's body but spreads widely from both the one and the other outlets and is delivered along the surface of the body, the user can feel comfortable.

[0033] (8) In the embodiment described in any one of (1) to (6) above, in the second air blower control device including one of the air outlets, it is preferable that the air outlet is formed in such a manner that it is bent in a substantially J-shape toward one direction with respect to the introduction portion.

[0034] According to this embodiment, the outlet of the air outlet can be positioned so as not to face the user's body. As a result, the temperature-controlled air supplied from the body ventilation device does not directly hit the user's body, but can be directed locally along the surface of the body towards the part of the user's body that they wish to receive the airflow.

[0035] (9) In the embodiment described in any one of (1) to (8) above, the air outlet portion has a wall member surrounding the flow path and a projection protruding from the wall member, and when the connecting portion is attached to the body blower, the projection is preferably formed on the portion of the wall member facing the inner housing portion of the body blower.

[0036] According to this embodiment, the projection functions as a rib to reinforce the wall member, thereby allowing the outlet section to be constructed with greater rigidity.

[0037] (10) Another embodiment of the body ventilation device with a blower control device made to solve the above problems is characterized in that a blower control device in any one of the embodiments of (1) to (9) above is detachably connected to the blower port of the body ventilation device, the body ventilation device being worn on the body, wherein the temperature-controlled air, which is either cold air that has passed through the cooling fins or warm air that has passed through the heat-dissipating fins, is blown out from the blower port, the blower control device in any one of the embodiments of (1) to (9) above is detachably connected to the blower port of the body ventilation device. The body ventilation device is being worn on the body, wherein the temperature-controlled air, which is either cold air that has passed through the cooling fins or warm air that has passed through the heat-dissipating fins, is blown out from the blower port.

[0038] In this configuration, the temperature-controlled airflow is directed along the surface of the user's body by the airflow control device, rather than directly hitting the user's body, thus allowing the user to feel comfortable. In addition, the airflow control device can efficiently direct the temperature-controlled airflow over a wide area along the surface of the user's body, towards the part of the user's body that they wish to receive the airflow from.

[0039] (11) Another body ventilation device in another aspect of the present disclosure made to solve the above problems comprises a housing having an outer housing portion having an air intake and an exhaust port formed therein, and an inner housing portion abutted and connected to the outer housing portion in an opposing position, a Peltier element disposed within the housing, a cooling fin formed on one surface of the Peltier element, a heat dissipation fin formed on the other surface opposite to the one surface, and a fan that introduces air from the air intake and sends air to the cooling fin and the heat dissipation fin, and is worn on the body, and the temperature-controlled air that is either cold air that has passed through the cooling fin or warm air that has passed through the heat dissipation fin is A body-use air blower that blows air from a blowing area is provided with a variable airflow member having an opening formed in such a manner that the temperature-controlled air can flow to the outside and a closing portion that blocks the flow of the temperature-controlled air to the outside, both arranged in different directions from each other; the housing that forms the cover of the body-use air blower includes a surrounding cutout portion in which a part of the space including the blowing area is left open; the surrounding cutout portion is provided at the connection point between a first side of the housing and a second side adjacent to the first side in a different direction; and the variable airflow member forms part of the housing and is attached to the surrounding cutout portion.

[0040] According to this embodiment, the body ventilation device allows the user to freely select the direction of the temperature-controlled airflow using a variable airflow direction member, according to their intended use. Therefore, when a user uses a body ventilation device they possess, the range of options for the installation configuration of the body ventilation device is wider, and the degree of freedom in how the body ventilation device is used is higher.

[0041] (12) Another embodiment of the present disclosure made to solve the above problems, a body blower with a blower control device comprising a housing comprising an outer housing portion having an intake port and an exhaust port formed therein, and an inner housing portion abutted and connected to the outer housing portion in a position opposite to it, 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 to the one side, and a blower fan that introduces air from the intake port and sends air to the cooling fin and the heat dissipation fin, and is worn on the body, and a temperature-controlled air, which is either cold air that has passed through the cooling fin or warm air that has passed through the heat dissipation fin, is blown out from the blower area, and the temperature-controlled air flows to the outside The airflow control member comprises an opening formed in a manner that allows air to pass through and a closing portion that blocks the flow of the temperature-controlled air to the outside, the openings of which are arranged in different directions from each other, the housing which forms the cover of the body blower includes a surrounding cutout portion in which a part of the space including the blower area is left open, the surrounding cutout portion is provided at the connection point between a first side of the housing and a second side adjacent to the first side in a different direction, and the airflow control member forms part of the housing and is attached to the surrounding cutout portion, wherein an airflow control device in any one of the above (1) to (9) is detachably attached to the opening of the airflow control member for a body blower.

[0042] According to this embodiment, since the main body of the body ventilation device with airflow control is equipped with a variable airflow direction member, the direction of the temperature-controlled airflow can be freely selected by the variable airflow direction member according to the user's needs. Therefore, when a user uses the body ventilation device with airflow control that they possess, there is a wider range of options in terms of its installation configuration, and the degree of freedom in how the body ventilation device with airflow control is used is higher.

[0043] Therefore, users can use the body-mounted fan with airflow control in various ways, such as by placing it in a clothing pocket, attaching it to a belt on work trousers, or attaching it to light clothing for use while jogging.

[0044] (13) In the aspect described in (11) or (12) above, the wind direction variable member can be reversibly attached to the surrounding missing portion in any of the first arrangement form in which the opening is disposed on the first side portion side and the closing portion is disposed on the second side portion side, and the second arrangement form in which the opening is disposed on the second side portion side and the closing portion is disposed on the first side portion side. It is preferably formed in a manner that can be attached.

[0045] According to this aspect, the body blower with a blower controller can change the direction of the opening through which the temperature-adjusted air is blown out according to the position of the body part of the user who wants to receive the temperature-adjusted air.

Furthermore, the body blower with the air blower control device described herein is configured by adding the air blower control device described herein to the main body blower.

[0063] The personal ventilation device and personal ventilation device with ventilation control device relating to this disclosure are used by people who particularly need cool air, such as workers wearing helmets while working outdoors in extreme heat, workers wearing work clothes in hot and humid indoor environments, and people engaging in recreation, sports, or spectating in the blazing sun. Alternatively, the personal ventilation device is used by people who particularly need warm air, such as workers with cold hands from doing water-related work in winter, or people who are exposed to cold winds outdoors and feel chilled while engaging in activities.

[0064] <Embodiment 1> [1. Overview of Body Air Blower] First, an overview of the body air blower to which the air blower control device according to this disclosure is to be attached will be briefly explained using Figures 1 to 7. The air blower control device according to this disclosure is applied to a body air blower that has a basic configuration consisting of the main parts of the body air blower 2A configured as shown in Figures 1 to 5.

[0065] Figure 1 is a perspective view showing the main part of a body ventilation device, which is given as an example of a mounting location for the airflow control device according to Embodiment 1. Figure 2 is an exploded perspective view of the main part of the body ventilation device shown in Figure 1. Figure 3 is a plan view of the body ventilation device shown in Figure 1, viewed from the outer housing side. Figure 4 is a perspective view of the body ventilation device shown in Figure 1, viewed from the inner housing side, and Figure 5 is a plan view viewed from the inner housing side. Figure 6 is a side view of the body ventilation device shown in Figure 1.

[0066] In the body ventilation device shown in Figure 1, the direction from the upper right to the lower left is defined as the X-axis direction, the direction from the lower right to the upper left is defined as the Y-axis direction, and the up and down direction is defined as the Z-axis direction. The directions defined in Figure 2 and subsequent figures will also follow those defined in Figure 1. In addition, the power supplies for the Peltier element 31 and the ventilation fan 35 are not shown in each figure.

[0067] As shown in Figures 1 to 7, the body ventilation device 2A(2) comprises 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. Each Peltier element unit 30 includes 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 the other surface 31b opposite it. The Peltier element 31 is electrically connected to a control unit 38 and a power supply (not shown) via a power supply port 39.

[0069] When a DC current is supplied from the power source to the Peltier element 31, due to the Peltier effect, one surface 31a absorbs heat and becomes a cooling surface, while the other surface 31b generates heat and becomes a heating surface. Furthermore, when the control unit 38 reverses the direction of the supplied DC current, the other surface 31b of the Peltier element 31 absorbs heat and becomes a cooling surface, while the one surface 31a generates heat and becomes a heating surface. In other words, when the control unit 38 reverses the direction of the DC current supplied to the Peltier element 31, the cooling surface and the heating surface are swapped between the one surface 31a and the other surface 31b.

[0070] The Peltier element 31 has the characteristic of simultaneously absorbing and generating heat at temperatures with a relative temperature difference from the ambient temperature, for example, within a temperature range of approximately 20 to 50°C. That is, for example, when the Peltier element 31 absorbs and generates heat under an ambient temperature of 35°C in summer, the cooling surface will exhibit a temperature of 15 to -15°C, and this heat will be used to cool the body. At the same time, the heating surface will exhibit a temperature of 55 to 85°C, and this heat will be used as waste heat.

[0071] On the other hand, when the Peltier element 31 absorbs and generates heat under an ambient temperature of 5°C in winter, the cooling surface exhibits a temperature of -15 to -45°C, and this heat is dissipated. Simultaneously, the heating surface exhibits a temperature of 25 to 55°C, and this heat becomes warmth for warming the body.

[0072] In this embodiment, a Peltier element 31 having a temperature characteristic that absorbs and generates heat simultaneously in a temperature range of approximately 20 to 50°C in comparison to the ambient temperature was given as an example.

[0073] However, the Peltier element is not limited to the temperature characteristics described in this embodiment. It may be configured with appropriate modifications as long as it has temperature characteristics that can cool the body to a degree that does not cause frostbite and warm the body to a degree that does not cause burns, using the temperature-controlled airflow FL described later. For example, the temperature characteristics of the Peltier element may have a temperature range of about 10 to 40°C or 10 to 20°C in relation to the ambient temperature.

[0074] Figure 7 is an explanatory diagram showing a Peltier unit configured in the body ventilation device shown in Figure 1. As shown in Figures 2 and 7, the heat sink 32 consists 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 are a pair. The blower-side heat sink 32A corresponds to either the cooling fins or the heat dissipation fins according to the disclosure, and the exhaust-side heat sink 32B corresponds to either the heat dissipation fins or the cooling fins according to the disclosure.

[0075] The blower-side heat sink 32A is formed to be large enough to contact almost the entire surface 31a of the Peltier element 31, and has numerous fins formed by folding back in a roughly corrugated shape, with gaps between adjacent fins, and is erected vertically from the flat plate portion 32Aa. The exhaust-side heat sink 32B is formed to be large enough to contact almost the entire surface 31b of the Peltier element 31, and has numerous fins formed by folding back in a roughly corrugated shape, with gaps between adjacent fins, and is erected vertically from the flat plate portion 32Ba.

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

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

[0078] Therefore, a grease layer 33 is interposed 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, filling these gaps with grease. The grease, for example, has relatively high thermal conductivity, such as satisfying a thermal conductivity of at least 5 W / m·K, and maintains relatively high viscosity within a temperature range from zero to around 100°C. By providing the grease layer 33, the heat generated by the Peltier element 31 is transferred to the heat sink 32 with reduced heat transfer loss on one surface 31a and the other surface 31b.

[0079] In this embodiment 1, the body ventilation device 2A(2) is configured with two Peltier element units 30 arranged side by side. However, the number of Peltier element units, each having a Peltier element, cooling fins, and heat dissipation fins, is not limited to two, and can be varied in various ways, such as one unit or three or more units.

[0080] Furthermore, the body ventilation device 2A(2) according to this embodiment 1 is configured in which two Peltier element units 30 are placed side by side, and each of the two Peltier elements exhibits heat absorption and heat generation. On the other hand, the Peltier element unit can also be configured by using one large Peltier element, for example, with heat absorption and heat generation characteristics similar to those of two small Peltier elements.

[0081] However, when comparing the first condition, which uses one large Peltier element, with the second condition, which uses two small Peltier elements, the second condition is sometimes superior to the first condition in terms of the response of the heat absorption and heat generation behavior of the Peltier elements. For this reason, the body ventilation device 2A, etc., according to this embodiment 1 is configured with two Peltier element units 30 placed side by side.

[0082] Furthermore, as shown in Figure 7, the Peltier element unit 30 is configured such that the fin cover 34 surrounds the entire area around the blower-side heat sink 32A and the exhaust-side heat sink 32B that are in contact with the Peltier element 31.

[0083] As shown in Figure 2, the blower fan 35 is installed in the internal space 10S of the housing 10, aligned with the position of the air intake port 21. In this embodiment, the blower fan 35 is a multi-blade blower (sirocco fan), which is a type of centrifugal blower. In addition to a sirocco fan, the blower fan may also be a propeller fan (axial flow), a turbo fan, or the like.

[0084] A sirocco fan is a roughly cylindrical blower in which multiple blades are arranged in a ring along the circumferential direction with respect to the central axis of rotation O. Air (wind) drawn in along the central axis is blown out radially outward from between the rotating blades. Unlike axial flow fans such as propeller fans and turbo fans, sirocco fans are less affected by external disturbances such as wind direction and wind strength, and they use centrifugal force acting on the drawn-in air to blow air, resulting in quieter operation.

[0085] On the other hand, since a sirocco fan uses centrifugal force acting on the inhaled air due to the rotation of multiple blades to blow air, the airflow force of a sirocco fan is generally smaller than that of axial flow fans such as propeller fans and turbo fans. For this reason, in the internal space 10S of the body ventilation device 2A according to this 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 narrowing passage 15, the airflow path width K2 is narrower than the airflow path width K1 passing through the center of rotation of the blower fan 35, so that the airflow force due to the airflow pressure, flow velocity, etc., is greater than that of the air blown by the blower fan 35, i.e., the temperature-controlled air FL described later.

[0087] The ratio of the flow path width K2 to the flow path width K1 is preferably, for example, within the range of 25% or more and 75% or less. This is because it allows for an increase in the airflow force supplied by the blower fan 35, while also ensuring that the airflow supplied by the blower fan 35 is evenly distributed to the two Peltier element units 30, thus achieving a good balance.

[0088] The housing 10 has an outer housing portion 11 and an inner housing portion 12A(2) as separate parts. The housing 10 is formed in a substantially flat shape with an internal space 10S, by joining the outer housing portion 11 and the inner housing portion 12A together in an opposing arrangement. The outer shape of the housing 10 is such that the outer peripheral edges of one side (upper side in the vertical direction in Figure 1) of the two long sides along the X-axis are connected by an arc, and the outer peripheral edges of the other side (lower side in the vertical direction in Figure 1) of these two long sides are connected by a straight short side along the Y-axis.

[0089] An internal space 10S exists between the outer housing portion 11 and the inner housing portion 12A. The outer housing portion 11 has an intake port 21 and an exhaust port 22, spaced apart in the X-axis direction. The inner housing portion 12A has an air outlet 23, located closer to the exhaust port 22 in the X-axis direction. As shown in Figures 2 and 5, an airflow adjustment wall 24 is formed in the internal space 10S of the housing 10, adjacent to the exhaust port 22 and the air outlet 23.

[0090] Figure 8 is a cross-sectional view taken along the line A-A in Figure 3, and is a schematic diagram showing the airflow in the internal space of the body ventilation device shown in Figure 1. As shown in Figures 1 to 3, the housing 10 has an air intake port 21 which is an opening in a part of the flat surface 11a of the outer housing portion 11. As shown in Figure 8, the air intake port 21 is a vent for supplying air AR introduced from the outside to the blower fan 35.

[0091] Furthermore, as shown in Figures 1 to 3, the housing 10 has an exhaust port 22 that is opened in a part of the flat surface 11a of the outer housing portion 11. As shown in Figure 8, the exhaust port 22 discharges the exhaust EX, which has passed through the exhaust-side heat sink 32B, to the outside, along with the air AR introduced into the internal space 10S from the intake port 21.

[0092] The exhaust-side heatsink 32B is covered by a fin cover 34. Therefore, when the air AR supplied from the blower fan 35 passes through the gaps between the fins of the exhaust-side heatsink 32B, the exhaust EX does not diffuse towards the blower-side heatsink 32A, etc. Instead, it is discharged through the gaps between the fins inside the exhaust-side heatsink 32B, along the airflow adjustment wall 24, and out of the exhaust port 22.

[0093] As shown in Figures 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 Figure 8, the air outlet 23 blows out the temperature-controlled air FL, which has passed through the air-blowing side heat sink 32A using air AR introduced into the internal space 10S from the intake port 21, along the airflow adjustment wall 24.

[0094] In the Peltier element 31, when one surface 31a is the cooling surface, the air AR supplied from the intake port 21 is cooled through heat exchange with the blower-side heat sink 32A, resulting in cold air CF as shown in Figure 8. Therefore, when one surface 31a is the cooling surface, this cold air CF becomes the temperature-controlled air FL.

[0095] In contrast, when one side 31a of the Peltier element 31 is the heating surface, the air AR supplied from the intake port 21 is heated through heat exchange with the blower-side heat sink 32A, resulting in warm air HF as shown in Figure 8. Therefore, when one side 31a is the heating surface, this warm air HF becomes the temperature-controlled air FL.

[0096] Similar to the exhaust-side heatsink 32B, the blower-side heatsink 32A is also covered by a fin cover 34. Therefore, in the blower-side heatsink 32A, when the air AR supplied from the blower fan 35 passes through the gaps between the fins, the temperature-controlled air FL does not diffuse towards the exhaust-side heatsink 32B, etc. Instead, it is discharged from the air outlet 23 along the air direction adjustment wall 24 through the gaps between the fins inside the blower-side heatsink 32A.

[0097] [2. Configuration of the Air Blower Control Device] Next, the air blower control device according to Embodiment 1 will be described using Figures 9 to 13. The air blower control device according to this disclosure is an attachment that is mounted on the air outlet 23 of a body blower device 2A, etc., as described above. The air blower control device 3 according to the embodiment controls the flow of temperature-controlled air FL blown out from the air outlet 23 of the body blower device 2A. The air blower control device 3 is made of resin.

[0098] Figure 9 is a perspective view of the air blower control device according to Embodiment 1, showing the air blower control device configured according to the specifications of Embodiment 1, and is a front view of the air blower control device shown in Figure 9. Figure 11 is a side view of the air blower control device shown in Figure 9. Figure 12 is a cross-sectional view taken along the line B-B in Figure 10.

[0099] In the air blower control device shown in Figure 9, the direction from the upper right to the lower left is defined as the W-axis direction, the direction from the lower right to the upper left is defined as the D-axis direction, and the vertical direction is defined as the H-axis direction. The directions defined in Figure 9 and subsequent figures relating to the air blower control device will also be the same as those defined in Figure 9.

[0100] As shown in Figures 9 to 12, in Embodiment 1, the air blower control device 103A (air blower control device 3) with the configuration according to Embodiment 1 corresponds to the air blower control device according to the present disclosure. The air blower control device 3 can be configured with multiple different specifications, as will be explained in Embodiment 2 and later. The air blower control device 103A is configured as one such specification.

[0101] The air blower control device 103A includes a connecting portion 110, an introduction portion 120A, an outlet portion 130, a flap 140, etc. The connecting portion 110 is formed to be detachably attached to the air outlet 23 of the body blower device 2A by at least one fixing means among fitting, fastening, and engaging.

[0102] In Embodiment 1, the connecting portion 110 is made of an elastic material such as silicone, silicone rubber, or rubber, and has enough flexibility to be easily elastically deformed by hand. The entire air blower control device 103A(3) may be made of such a flexible elastic material. Alternatively, only the connecting portion 110 of the air blower control device 103A(3) may be made of such a flexible elastic material.

[0103] The connecting portion 110 is frame-shaped, surrounding the entire circumference of the inlet 121, and is formed to be flexible, including a recessed groove 111. The air blower control device 103A is attached by elastically deforming the connecting portion 110 to fit the groove 111 of the connecting portion 110 with the flange 26 of the mounting-side connecting portion 25 of the body blower 2A, thereby connecting it to the air outlet 23 of the body blower 2A.

[0104] As an example of a fixing means for connecting the air blower control device 103A (3) and the body blower device 2A, Embodiment 1 provides a fitting means using the groove 111 of the connection portion 110 of the air blower control device 103A and the flange 26 of the mounting side connection portion 25 of the body blower device 2A.

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

[0106] Alternatively, as a means of fixing, one claw piece provided on the air blower control device 3 is engaged with one engaging portion at one end of an opening in the inner housing. In this state, the other claw piece provided on the air blower control device 3 is engaged with the other engaging portion on the opposite side of the opening while elastically deforming, thereby connecting the fixed part and the fixed part.

[0107] As shown in Figure 11, the air blower control device 103A is formed in a roughly L-shape when viewed from the side. A hollow flow path FP is formed in communication between the introduction section 120A and the discharge section 130. The flow path FP is formed between the inlet 121 of the introduction section 120A and the outlet 131 of the discharge section 130. In the outlet-side flow path FPe that passes through the discharge 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 installed on the air outlet 23, the introduction part 120A is the part that takes in the temperature-controlled air FL blown out from the air outlet 23 into the inlet 121 of the flow path FP. The discharge part 130 extends from the introduction part 120A and has an outlet 131 that sends the temperature-controlled air FL that has passed through the flow path FP to the outside.

[0109] In the air blower control device 103A, as shown in Figures 9 and 10, the outlet-side airflow path FPe within the blower section 130 is divided into three sections by two partition walls 132. The two partition walls 132 are arranged in a manner that they are inclined so that they are further apart from each other as they approach the outlet 131.

[0110] In the configuration according to Embodiment 1, a flap 140 is provided in the introduction section 120A. The flap 140 is a component that changes the direction of the temperature-controlled airflow FL flowing through the flow path FP. As shown in Figures 11 and 12, the flap 140 is pivotable around a pivot shaft 141 in the introduction section 120A, and opens or closes the opening 142 formed in the introduction section 120A.

[0111] As shown in Figure 12, when the flap 140 is open, the temperature-controlled air FL that flows into the inlet 121 is divided into a main flow that goes to the outside from the outlet 131 and a branch flow that goes to the outside from the opening 142 which is facing a different direction from the outlet 131. Conversely, when the flap 140 is closed, the temperature-controlled air FL is blown to the outside only by the main flow from the outlet 131.

[0112] Figure 13 is a perspective view showing the air blower control device according to Embodiment 1, configured according to the specifications of Embodiment 2. As shown in Figure 13, the air blower control device 103B(3) configured according to Embodiment 2 also corresponds to the air blower control device according to this disclosure.

[0113] In the configuration according to Embodiment 2, the air blower control device 103B has a connection part 110, an introduction part 120B, a discharge part 130, etc. Unlike the air blower control device 103A, the introduction part 120B does not have a flap or opening. Therefore, the temperature-controlled air FL flows from the connection part 110 side through a flow path FP that extends directly to the discharge part 130 side and is blown out to the outside.

[0114] <Embodiment 2> Next, the air blower control device according to Embodiment 2 will be described using Figures 14 to 17. The air blower control device according to Embodiment 2 differs from that of Embodiment 1 in that it has two air outlets.

[0115] In Embodiment 2, the explanation will focus on the parts that differ from Embodiment 1, and the explanation of parts that are common to Embodiment 1 will be simplified or omitted by using a symbol where the first digit is 2 and the last two digits are the same, for example, as in the connection part 110 of Embodiment 1 and the connection part 210 of Embodiment 2, where only the first digit is changed from 1 to 2 and the last two digits remain the same, 10.

[0116] Figure 14 is a perspective view of the air blower control device according to Embodiment 2, when configured according to the specifications of Embodiment 1. Figure 15 is a front view of the air blower control device shown in Figure 14, and Figure 16 shows a side view of the air blower control device. Figure 17 is a cross-sectional view taken along the line C-C in Figure 16.

[0117] As shown in Figures 14 to 16, in Embodiment 2, the air blower control device 203A (3) with the configuration according to Embodiment 1 corresponds to the first air blower control device according to the present disclosure. The air blower control device 203A has a connection part 210, an introduction part 220A, a discharge part 230, etc. The air blower control device 203A has a hollow flow path FP which is the flow path for the temperature-controlled air FL. The flow path FP is formed to communicate between the introduction part 220A and the discharge part 230.

[0118] In Embodiment 2, the connecting portion 210 is made of an elastic material such as silicone, silicone rubber, or rubber, and has enough flexibility to be easily deformed by hand. The connecting portion 210 is frame-shaped, surrounding the entire circumference of the inlet 221, and is formed in a manner that includes a recessed groove 211. The air blower control device 203A (3) is attached in a state connected to the air outlet 23 of the body blower 2A by elastically deforming the connecting portion 210 and fitting the groove 211 of the connecting portion 210 with the flange 26 of the mounting-side connecting portion 25 of the body blower 2A (2).

[0119] Furthermore, as an example of a fixing means for connecting the air blower control device 203A and the body blower device 2A, Embodiment 2 provides a fitting means using the groove 211 of the connection portion 210 of the air blower control device 203A and the flange 26 of the mounting side connection portion 25 of the body blower device 2A.

[0120] However, in the air blower control device 203A(3), a part to be fixed is provided on the inner housing of the body blower device 2, and a part to be fixed is also provided on the air blower control device 3, and the fixing means may be, for example, screw fastening, engagement of a convex part and a concave part to connect the part to be fixed.

[0121] Alternatively, as a means of fixing, one claw piece provided on the air blower control device 3 is engaged with one engaging portion at one end of an opening in the inner housing. In this state, the other claw piece provided on the air blower control device 3 is engaged with the other engaging portion on the opposite side of the opening while elastically deforming, thereby connecting the fixed part and the fixed part.

[0122] In the air blower control device 203A, as shown in Figures 14 to 16, the blowing section 230 is formed in a manner in which it branches into two and bends in different directions, separated by the inlet section 220A. That is, the blowing section 230 consists of a first blowing section 230a and a second blowing section 230b. The first blowing section 230a and the second blowing section 230b are arranged in a substantially V-shape symmetrical manner on a virtual axis along the H-axis direction.

[0123] Furthermore, the angle at which the first and second discharge sections 130a and 130b open in a V-shape with respect to a virtual axis along the H-axis is not particularly limited and can be changed as appropriate. Also, the inclination angle of the first discharge section 230a and the inclination angle of the second discharge section 330b may be different.

[0124] In the outlet-side flow path FPe passing through the first discharge 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 discharge 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-controlled airflow FL is blown into the inlet 221 of the introduction section 220A, it is blown out from the introduction section 220A through the outlet-side flow path FPe of the first discharge section 230a to the outside from the first outlet 231a. At the same time, the temperature-controlled airflow FL is blown out from the introduction section 220A through the outlet-side flow path FPe of the second discharge section 230b to the outside from the second outlet 231b.

[0126] In other words, in the air blower control device 203A, the temperature-controlled air FL is blown out in a roughly V-shape, splitting into a first outlet 231a of the first outlet section 230a and a second outlet 231b of the second outlet section 230b.

[0127] Figure 18 is a cross-sectional view of the air blower control device according to Embodiment 2, when configured according to the specifications of Embodiment 2, viewed from a position corresponding to the position indicated by the line C-C in Figure 16. As shown in Figure 18, the air blower control device 203B(3) configured according to Embodiment 2 also corresponds to the air blower control device according to the present disclosure.

[0128] In the configuration according to Embodiment 2, the air blower control device 203A includes a connection part 210, an introduction part 220A, a discharge part 230, a flap 240, etc. In the configuration according to Embodiment 2, the flap 240 is provided in the introduction part 220B. As shown in Figure 18, the flap 240 is pivotable around a pivot axis 241 in the introduction part 220B, and opens or closes the opening 242 formed in the introduction part 220B.

[0129] <Embodiment 3> Next, the air blower control device according to Embodiment 3 will be described using Figures 19 to 24. The air blower control device according to Embodiment 3 differs from Embodiment 2 in that the two air outlets are arranged on opposite sides of each other with respect to one direction.

[0130] In Embodiment 3, the explanation will focus on the parts that differ from Embodiment 2, and the explanation of parts common to Embodiments 1 and 2 will be simplified or omitted by using a symbol where the first digit is 2 and the last two digits are the same, for example, as in the connection part 110 of Embodiment 1 and the connection part 310 of Embodiment 3, where only the first digit is changed from 1 to 3 and the last two digits remain the same, 10.

[0131] Figure 19 is a perspective view of the air blower control device according to Embodiment 3, viewed from the outside, and Figure 20 shows a perspective view of the air blower control device viewed from the inside. Figure 21 is a front view of the air blower control device shown in Figure 20, viewed from the inside, and Figure 22 shows a cross-sectional view taken along the line E-E in Figure 21.

[0132] As shown in Figures 19 to 22, the air blower control device 303 (3) according to Embodiment 3 corresponds to the first air blower control device according to the present disclosure. The air blower control device 303 has a connection part 310, an introduction part 320, a flow guide part 325, a discharge part 330, etc. The air blower control device 303 has a hollow flow path FP which is the flow path of the temperature-controlled air FL. The flow path FP is formed to communicate between the introduction part 320 and the discharge part 330.

[0133] In Embodiment 3, the connecting portion 310 is made of an elastic material such as silicone, silicone rubber, or rubber, and has enough flexibility to be easily elastically deformed by hand. The connecting portion 310 is formed in a frame-like shape that surrounds the entire circumference of the inlet 321 and includes a recessed groove 311.

[0134] Furthermore, as an example of a fixing means for connecting the air blower control device 303 (3) and the body blower device 2A, in Embodiment 2, a fitting means was given using the groove 311 of the connection portion 310 of the air blower control device 303 and the flange 26 of the mounting side connection portion 25 of the body blower device 2A.

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

[0136] Alternatively, as a means of fixing, one claw piece provided on the air blower control device 3 is engaged with one engaging portion at one end of an opening in the inner housing. In this state, the other claw piece provided on the air blower control device 3 is engaged with the other engaging portion on the opposite side of the opening while elastically deforming, thereby connecting the fixed part and the fixed part.

[0137] In the air blower control device 303(3), as shown in Figures 19 to 22, the blowing section 330 is formed in such a manner that it branches and bends into two parts in opposite directions with respect to the H-axis, with the introduction section 320 as the boundary. That is, the blowing section 230 consists 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 manner that is slightly inclined with respect to the D-axis, closer to the connection section 310 from the introduction section 320.

[0138] Furthermore, the angle at which both the first discharge section 330a and the second discharge section 330b tilt toward the connection section 310 with respect to the D-axis is not particularly limited and can be changed as appropriate. Also, the tilt angles of the first discharge section 330a and the second discharge section 330b may be different.

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

[0140] In the outlet-side flow path FPe passing through the first discharge 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 in both cases. Similarly, in the outlet-side flow path FPe passing through the second discharge 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] As shown in Figure 22, the flow guide section 325 is formed in the flow path FP within the introduction section 320. The flow guide section 325 is provided to easily guide the temperature-controlled air FL taken into the introduction section 320 toward the first outlet section 330a and the second outlet section 330b. As the temperature-controlled air FL flows through the flow path FP surrounded by the inner wall of the air blower control device 303, the flow guide section 325 suppresses excessive turbulence caused by a decrease in flow velocity and pressure loss as it flows along the inner wall, allowing it to flow toward the outlet section 331.

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

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

[0144] Figure 23 is an explanatory diagram showing a perspective view of the airflow control device according to Embodiment 2 before it is connected to the attachment-side connection part of the body airflow device exemplified in Embodiment 1. Figure 24 is an explanatory diagram showing a perspective view of the airflow control device according to Embodiment 2 after it has been connected to the attachment-side connection part of the body airflow device exemplified in Embodiment 1.

[0145] The air blower control device 303(3) is attached in a connected state to the air outlet 23 of the body blower 2B by the elastic deformation of the connecting portion 310, as shown in Figures 23 and 24, by fitting the groove 311 of the connecting portion 310 with the flange 26 of the mounting side connecting portion 25 of the body blower 2B(2).

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

[0147] In the body ventilation device 2B(2), the housing 10 is constructed by separating the outer housing portion 11 and the inner housing portion 12B(12). The outer housing portion 11 is the same for both the body ventilation device 2A(2) and the body ventilation device 2B(2). The body ventilation device 2B(2) is constructed by changing the inner housing portion 12A(12) of the body ventilation device 2A(2) to the inner housing portion 12B(12).

[0148] <Embodiment 4> Next, the air blower control device according to Embodiment 4 will be described with reference to Figures 25 to 29. The air blower control device according to Embodiment 3 differs from Embodiment 2 in that the two air outlets are arranged in one direction but on opposite sides of each other.

[0149] In Embodiment 4, the explanation will focus on the parts that differ from Embodiments 1 to 4. The explanation of parts common to Embodiments 1 to 3 will be simplified or omitted by using a reference numeral with the first digit set to 4 and the last two digits set to the same, for example, since the connection part 410 in Embodiment 4 is the same as the connection part 110 in Embodiment 1, only the first digit is changed from 1 to 4, and the last two digits remain the same, 10.

[0150] Figure 25 is a perspective view showing the air blower control device according to Embodiment 4, and a front view of the air blower control device is shown in Figure 26. Figure 27 is a cross-sectional view taken along the line F-F in Figure 26. Figure 28 is a perspective view explanatory diagram showing the state of the air blower control device according to Embodiment 4 before it is connected to the attachment-side connection part of the body blower device exemplified in Embodiment 1. Figure 29 is a perspective view explanatory diagram showing the state of the air blower control device according to Embodiment 4 after it has been connected to the attachment-side connection part of the body blower device exemplified in Embodiment 1.

[0151] As shown in Figures 25 to 29, the air blower control device 403(3) according to Embodiment 4 corresponds to the second air blower control device according to the present disclosure. The air blower control device 403 has a connection part 410, an introduction part 420, a discharge part 430, a fixing part 450, etc. The air blower control device 403 has a hollow flow path FP which is the flow path for the temperature-controlled air FL. The flow path FP is formed to communicate between the introduction part 420 and the discharge part 430.

[0152] As shown in Figures 25 to 28, the connecting portion 410 is formed in the shape of a frame that surrounds the entire circumference of the inlet 421 of the introduction portion 420. In the air blower control device 403, one outlet portion 430 is formed in a shape that is bent downward in the H-axis direction in a roughly J-shape, with the introduction portion 420 as the boundary. The outlet portion 430 has a wall member 432 that surrounds the flow path FP and a plurality of protrusions 433 that protrude from the wall member 432.

[0153] In the outlet-side flow path FPe, which passes through the discharge section 430, the discharge section 430 is formed in such a way that the cross-sectional area S1 on the outlet side 431 is smaller than the cross-sectional area S2 on the inlet side 421 of the introduction section 420. Therefore, the outer surface 432a of the wall member 432 is inclined downward in the H-axis direction.

[0154] As shown in Figures 28 and 29, when the connecting portion 410 is attached to the body ventilation device 2C (2), the projections 433 of the wall member 432 are formed on the portion facing the inner housing portion 12C of the body ventilation device 2C. Specifically, the multiple projections 433 are formed on the outer surface 432a of the wall member along the H-axis direction. Furthermore, these multiple projections 433 have a certain gap between adjacent projections 433 and are arranged in alignment along the Y-axis direction. As shown in Figure 27, all of the projections 433 are convex in a mountain-like shape when viewed from the side in the Y-axis direction.

[0155] In the body ventilation device 2C(2), the housing 10 has an outer housing portion 11 and an inner housing portion 12C(12) as separate components. The outer housing portion 11 is the same in the body ventilation device 2A(2) and the body ventilation device 2C(2), and the body ventilation device 2C(2) is constructed by changing the inner housing portion 12A(12) of the body ventilation device 2A(2) to the inner housing portion 12C(12).

[0156] The inner housing portion 12C has a fixed portion 50 formed to engage with a fixing portion 450 on the air blower control device 403. The fixing portion 450 corresponds to the fixing portion according to this disclosure. Specifically, when connecting to the body blower device 2C, the fixing portion 450 is formed on the connecting portion 410. On the other hand, the inner housing portion 12C of the body blower device 2C has a fixed portion 50 formed on it. The fixed portion 50 corresponds to the fixed portion according to this disclosure.

[0157] In Embodiment 4, the fixing portion 450 has one engaging piece 451 on the lower side of the connecting portion 410 (lower side in the H-axis direction in Figure 25), and two screw fastening portions 452 on both the left and right sides (both sides in the W-axis direction in Figure 25) flanking the engaging piece 451, and on the upper side of the connecting portion 410 (upper side in the H-axis direction in Figure 25). The engaging piece 451 is formed in a substantially L-shape. The claws of the engaging piece 451 are flexible within the range of elastic deformation. The screw fastening portions 452 are formed, for example, in a manner that includes a male screw to be inserted and a female screw that can be screwed into within a boss, or in a manner in which a nut is inserted within a boss.

[0158] In Embodiment 4, the fixed portion 50 has one engagement groove 51 on the lower side of the air outlet 23 (lower side in the H-axis direction in Figure 28), and two screw fastening portions 52 on both the left and right sides of the engagement groove 51 (both sides in the W-axis direction in Figure 28) and on the upper side of the air outlet 23 (upper side in the H-axis direction in Figure 28). The engagement groove 51 is formed in a shape that has a groove that can engage with the claw of the engagement piece 451. The screw fastening portions 52 have through holes through which screw fastening members such as screws and bolts can be inserted.

[0159] When attaching the connecting portion 410 to the inner housing portion 12C (12) of the body ventilation device 2C (2), the engaging piece 451 of the fixing portion 450 of the air blower control device 403 (3) and the engaging groove 51 of the fixed portion 50 of the inner housing portion 12C are first engaged. Next, the air blower control device 403 is connected to and attached to the body ventilation device 2 by fixing the fixing portion 450 and the fixed portion 50 with screws. As a result, the air outlet 23 of the body ventilation device 2 and the connecting portion 410 of the air blower control device 403 are connected.

[0160] With the air blower control device 403(3) attached to the body blower device 2C(2), when the temperature-controlled air FL is blown into the inlet 421 of the introduction section 420 of the air blower control device 403(3), it flows smoothly from the introduction section 420 to the discharge section 430 and is blown out to the outside from the outlet 431 through the outlet-side flow path FPe.

[0161] In addition, as an example of a fixing means for connecting the air blower control device 403(3) and the body blower device 2C, in Embodiment 4, screw fastening between the fixing part 450 and the part to be fixed 50 was given.

[0162] However, in the case of the air blower control device 3, the air blower control device 3 may be attached to the body blower device 2 by a fitting means between a groove in a frame-shaped connection part and a flange on the attachment side connection part formed at the air outlet of the body blower device 2, as in the connection part 110 according to Embodiment 1.

[0163] [3. Configuration of a body ventilation device, configuration of a body ventilation device with a ventilation control device] <Embodiment 5> Next, a body ventilation device with a ventilation control device according to Embodiment 5 will be described using Figures 30 to 37.

[0164] Embodiment 5 will primarily describe the parts that differ from Embodiments 1 to 4, while the descriptions of parts common to Embodiments 1 to 4 will be simplified or omitted using the same reference numerals.

[0165] Figure 30 is a perspective view showing the body ventilation device with a blower control according to Embodiment 5, but using the blower control according to Embodiment 1, and shows the state before the helmet mounting part is attached to the body ventilation device with a blower control. Figure 31 follows Figure 30 and shows the state after the helmet mounting part has been attached to the body ventilation device with a blower control. Figure 32 is a side view showing the body ventilation device with a blower control according to Embodiment 5 attached to a helmet, and shows the case when the blower control according to Embodiment 1 is used. Figure 33 is a perspective view showing the body ventilation device with a blower control according to Embodiment 5 attached to a helmet, and shows the case when the blower control according to Embodiment 1 is used.

[0166] Figure 34 is a schematic diagram showing the airflow inside the head of a user wearing a helmet equipped with the body ventilation device with airflow control according to Embodiment 5, viewed from the side, and shows the case when the airflow control according to Embodiment 1 is attached to this body ventilation device with airflow control. Figure 35 is a schematic diagram showing the airflow inside the head of a user wearing a helmet equipped with the body ventilation device with airflow control according to Embodiment 5, viewed from the rear of the head, and shows the case when the airflow control according to Embodiment 1 is attached to this body ventilation device with airflow control.

[0167] Figure 36 is a perspective view showing the body ventilation device with airflow control according to Embodiment 5 with a helmet mounting part attached, and shows the case when the airflow control according to Embodiment 2 is used. Figure 37 is a schematic diagram of the airflow inside the head of a user wearing a helmet equipped with the body ventilation device with airflow control according to Embodiment 5, viewed from the rear of the head, and shows the case when the airflow control according to Embodiment 2 is used in this body ventilation device with airflow control.

[0168] The body ventilation devices 1A and 1B (1) with airflow control devices according to Embodiment 5 correspond to the body ventilation devices with airflow control devices according to the present disclosure.

[0169] As shown in Figures 30 to 35, the body ventilation device 1A with a ventilation control is a first embodiment device in which, as shown in Figure 9 and the like, a ventilation control 103A, a body ventilation device 2D, and a helmet mounting part 550 are installed. In addition, a ventilation control 103B(3) may be installed instead of the ventilation control 103A(3).

[0170] Furthermore, as shown in Figures 36 and 37, the body ventilation device 1B with a ventilation control is a second embodiment of the device in Embodiment 1, consisting of a ventilation control 203B, a body ventilation device 2D, and a helmet mounting part 550, as shown in Figure 13, etc. Note that a ventilation control 203A may be attached instead of the ventilation control 203B.

[0171] The body ventilation device 2D(2) will be described with reference to Figures 30 and 31. As shown in Figures 30 and 31, in the body ventilation device 2D(2), the housing 10 consists of an outer housing portion 11 and an inner housing portion 12D(12), each being a separate unit. A retaining guide portion 510 is formed on the flat surface 12d of the inner housing portion 12D. The retaining guide portion 510 corresponds to the fixing portion according to this disclosure.

[0172] As shown in Figure 30, the retaining guide portion 510 has a pair of guide members 511. The guide members 511 are formed in a substantially L-shape, and the tip of each guide member 511 is a retaining piece 512. The two guide members 511 are positioned with their respective retaining pieces 512 facing each other, spaced apart in the W-axis direction, and extending parallel to each other along the H-axis direction, and are erected on the flat plate surface 12d. The retaining guide portion 510 fixes and holds the attached helmet mounting portion 550.

[0173] As shown in Figures 30 to 35, the helmet shell mounting portion 550, along with a strip-shaped member 580, is an auxiliary member for attaching the body ventilation device 1A, 1B(1) with a ventilation control device to the helmet shell 571 of the helmet 570. The strip-shaped member 580 is a well-known member formed in a strip shape, such as a rubber belt or a band with adjustable length.

[0174] In addition to using the strip-shaped member 580 when attaching the body-mounted ventilation device 1 with a ventilation control to the helmet shell 571, the body-mounted ventilation device 1 with a ventilation control and the helmet shell mounting portion 550 may also be connected by a connection means that can be easily attached and detached, such as screw fastening or snap button engagement.

[0175] As shown in Figure 30, the helmet mounting portion 550 is formed in a roughly plate-like shape that is curved in an arc to match the outer circumference shape of the surface of the helmet 571. The helmet mounting portion 550 has a base portion 551 in the center and one strap mounting portion 553 at each end thereof.

[0176] The base portion 551 is provided with two engagement grooves 552. The engagement grooves 552 are formed to be able to engage with the guide member 511 of the retaining guide portion 510, which is disposed on the body ventilation device 2D(2). In both locations, the helmet mounting portion 550 is fixed to the retaining guide portion 510 by inserting the engagement grooves 552 through the guide member 511 and holding the base portion 551 with the retaining piece 512 of the guide member 511.

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

[0178] Next, as shown in Figures 33 and 34, the strip-shaped member 580 is wrapped around the outer peripheral edge at the lower end of the helmet body 571, and the strip-shaped member 580 is inserted through the mounting hole 554 of the helmet body mounting portion 550 attached to the body ventilation device 2D (12) of the body ventilation device 1A etc. (1) with a ventilation control device.

[0179] Next, the air blower control device 103A is positioned close to the outer edge of the helmet shell 571, and with the helmet shell mounting portion 550 in close contact with the helmet shell 571, the body-type air blower device 1A(1) with the air blower control device is fastened and attached to the helmet shell 571 by the strip-shaped member 580 with a tightening tension adjusted to prevent it from falling.

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

[0181] Furthermore, when the flap 140 of the airflow control device 103A is open, the temperature-controlled airflow FL is blown not only into the helmet's internal space 570S but also towards the neck of the user HM.

[0182] In the case of the body ventilation device 1B with a blower control, as shown in Figure 37, the temperature-controlled air FL is blown out from the air outlet 23 of the body ventilation device 2D through the outlet 131 of the blower control 203B. As a result, the temperature-controlled air FL is blown into the helmet's internal space 570S, and onto the head of the user HM wearing the helmet 570, along the scalp and upward.

[0183] As mentioned above, the body ventilation devices 1A and 1B with a ventilation control device, including the body ventilation device 2D, are examples of body ventilation devices with a ventilation control device that are attached to the helmet shell 571 of the helmet 570.

[0184] However, as will be described later, the body ventilation device with a ventilation control that is attached to the helmet shell 571 of the helmet 570 also applies to the body ventilation device with a ventilation control 1X (1Xu, 1Xv) which includes the body ventilation device 2E in Embodiment 9. However, when using the body ventilation device with a ventilation control (1Xu, 1Xv), it is important that the holding guide portion 510 is formed in the inner housing portion corresponding to the inner housing portion 812 of the body ventilation device 2E of the body ventilation device with a ventilation control (1Xu, 1Xv).

[0185] In other words, in a body ventilation device configured as a body ventilation device with a ventilation control device to be attached to the helmet shell 571 of a helmet 570, the housing only needs to be composed of a first inner housing portion with a fixing portion provided on the inner housing portion 812 and an outer housing portion 811. The fixing portion is a retaining guide portion configured to be detachable from the helmet shell mounting portion 550, such as the retaining guide portion 510 of the body ventilation device 2D.

[0186] <Embodiment 6> Next, a body ventilation device with a ventilation control device according to Embodiment 6 will be described with reference to Figures 38 to 41.

[0187] Embodiment 6 will primarily describe the parts that differ from Embodiments 1 to 5, while the descriptions of parts common to Embodiments 1 to 5 will be simplified or omitted using the same reference numerals.

[0188] Figure 38 is a perspective view showing a first example of attaching the body-type air blower with air blower control device according to Embodiment 6 to clothing, specifically when it is attached to the collar. Figure 39 shows the state of the body-type air blower with air blower control device according to Embodiment 6 before it is attached to the collar of the clothing, and Figure 40 shows an explanatory diagram showing the body-type air blower with air blower control device being used after it has been attached to the collar of the clothing. Figure 41 is a schematic diagram showing the airflow inside the clothing when the body-type air blower with air blower control device according to Embodiment 6 is attached to the collar.

[0189] As shown in Figures 38 to 41, the body ventilation device 1C(1) with a ventilation control is a third embodiment of the device, consisting of a ventilation control 403(3) and a body ventilation device 2C(2), as shown in Figure 29 and the like.

[0190] In the body ventilation device 2C(2), the housing 10 consists of a separate outer housing portion 11 and an inner housing portion 12C(12). The inner housing portion 12C has a fixed portion 50 formed to be engageable with a fixing portion 450 on the ventilation 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 fixed portion according to the present disclosure.

[0191] The air blower control device 403(3) is attached to the body blower device 2 by engaging the engaging piece 451 of the fixing portion 450 with the engaging groove 51 of the fixed portion 50 of the inner housing portion 12C(12), and by fixing the fixing portion 450 and the fixed portion 50 with screws.

[0192] <First Example of Use of Body Air Blower with Air Blower Control> The body air blower 1C(1) with an air blower control has an attachment portion 60 for clothing that can be attached to the collar 610 of clothing 600 worn by the user HM, the edge near the buttons of a dress shirt, the sleeve, etc. Specifically, the attachment portion 60 for clothing is a gap formed between the outer surface 432a and projection 433 of the wall member 432 of the air blower control 403 and the flat surface 12a of the inner housing portion 12C of the housing 10 of the body air blower 2C, as shown in Figures 25, 28, 39, and 40.

[0193] The attachment part to the garment may be a component that can be connected to the garment, such as a clip or other gripping means, or a snap button.

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

[0195] Furthermore, when the body-type air blower 1C with air blower control is attached to the collar 610 of the garment 600, the air outlet 430 of the air blower control 403 is positioned between the garment 600 and the user's body (HM), as shown in Figure 41. This allows the temperature-controlled airflow FL to be directed towards the upper body, such as the user's back and neck.

[0196] <Embodiment 7> Next, a body ventilation device with a ventilation control device according to Embodiment 7 will be described with reference to Figures 42 to 45.

[0197] Embodiment 7 will primarily describe the parts that differ from Embodiments 1 to 6, while the descriptions of parts common to Embodiments 1 to 6 will be simplified or omitted using the same reference numerals.

[0198] Figure 42 is a front view showing a body-mounted ventilation device with a ventilation control according to Embodiment 7, illustrating the configuration when it is directly attached to the body. Figure 43 is a perspective view from behind the body showing the body-mounted ventilation device with a ventilation control shown in Figure 42 directly attached to the body. Figure 44 is a view from the side of the body showing the body-mounted ventilation device with a ventilation control shown in Figure 42 in use. Figure 45 is a schematic diagram showing the airflow to the body by the body-mounted ventilation device with a ventilation control shown in the cross-sectional view along the line A-A in Figure 42.

[0199] As shown in Figures 42 to 45, the body ventilation device 1D(1) with a ventilation control is a fifth embodiment of the device, consisting of a ventilation control 303(3) and a body ventilation device 2B(2), as shown in Figure 24 and the like, in Embodiment 3.

[0200] <Second Example of Use of Body Ventilation Device with Airflow Control> In the body ventilation device 1D (1) with an airflow control, as shown in Figures 23 and 24, the airflow control 303 (3) is attached in a state where it is connected to the air outlet 23 of the body ventilation device 2B (2). The airflow control 303 is connected by the elastic deformation of the connection part 310, which causes the groove 311 of the connection part 310 to fit with the flange 26 of the mounting side connection part 25 of the body ventilation device 2A. The airflow control 303 and the body ventilation device 2A are detachable.

[0201] As shown in Figures 23 and 24, the body-type air blower 2B has support parts 16 formed at the four corners of the inner housing part 12C, etc. As a result, as shown in Figures 42 to 44, a belt-shaped support member 700, such as a belt or string, can be connected to the support parts 16. When a user HM wears the body-type air blower 1D with an air blower control device directly on their body, such as their upper body or limbs, the user HM can use the body-type air blower 1D with an air blower control device by securing it with the support member 700, thereby positioning it on the user HM's body and maintaining direct contact with it.

[0202] Specifically, as shown in Figure 43, when the body-type air blower with air blower control 1D (1) is used on the upper body of the user HM, the user HM can use the body-type air blower with air blower control 1D, with the air blower control 303 (3) attached to the air outlet 23, by suspending it across the upper body of the user HM via a support member 700 connected to the supported part 16. As a result, as shown in Figure 45, the temperature-controlled air FL is blown along the surface of the user HM's body at the position where the body-type air blower with air blower control 1D is placed, including the upper body such as the user HM's back and neck.

[0203] <Embodiment 8> Next, a body ventilation device with a ventilation control device according to Embodiment 8 will be described with reference to Figures 46 to 48.

[0204] Embodiment 8 will primarily describe parts that differ from Embodiments 1 to 7, while descriptions of parts common to Embodiments 1 to 7 will be simplified or omitted using the same reference numerals.

[0205] <Third Example of Use of Body Air Blower with Airflow Control Device> Figure 46 is a perspective view showing a third example of use in which the body air blower with airflow control device according to Embodiment 8 is housed in a pocket of clothing. Figure 47 is a schematic diagram showing the airflow to the body when the airflow control device according to Embodiment 4 is used with the body air blower with airflow control device according to Embodiment 8. Figure 48 is a schematic diagram showing the airflow to the body when the airflow control device according to Embodiment 3 is used with the body air blower with airflow control device according to Embodiment 8.

[0206] As mentioned above, in addition to the body-type ventilation device 1C(1) with a ventilation control, the body-type ventilation device 1D(1) with a ventilation control is used by being housed in the pocket 620 of the garment 600B, as shown in Figure 46. In the body-type ventilation device 1C(1), the ventilation control 403(4) and the body-type ventilation device 2C(2) are detachable. In the body-type ventilation device 1D(1), the ventilation control 303(3) and the body-type ventilation device 2A(2) are detachable.

[0207] <Third Example of Use of Body-Mounted Ventilation Device with Airflow Control> As shown in Figures 47 and 48, an opening 621 is formed inside the pocket 620 of the garment 600B by opening a part of the garment 600B, and the opening 621 penetrates between the inside of the pocket 620 and the body side of the garment 600B, with the fabric of the garment 600B in between. The pocket 620 is formed to a size that allows the air outlet 23 of the body-mounted ventilation device 1C and the connection part 410 and introduction part 420 of the airflow control device 403 to be connected between the inside of the pocket 620 and the body side of the garment 600B.

[0208] When user HM uses the body-type air blower 1C(1) with an air blower control device, as shown in Figure 47, by placing it inside the pocket 620 of the garment 600B, the temperature-controlled air FL is blown out from the outlet 431 of the outlet 430 of the air blower control device 403(4) and blown along the surface of user HM's body towards the lower body on the body side of the garment 600B.

[0209] When user HM uses the body-type air blower 1D(1) with an air blower control device, as shown in Figure 48, by placing it inside the pocket 620 of the garment 600B, the temperature-controlled air FL is blown out from the first outlet 331a of the first outlet 330a of the air blower control device 303(3) along the surface of user HM's body and directed towards the upper body and neck above the pocket 620. At the same time, the temperature-controlled air FL is blown out from the second outlet 331b of the second outlet 330b of the air blower control device 303(3) along the surface of user HM's body and directed towards the lower body below the pocket 620.

[0210] In the body ventilation device 1D(1) with a blower control, as shown in Figures 23 and 24, the blower control 303(3) is mounted in a state where it is connected to the air outlet 23 of the body ventilation device 2B. The blower control 303(3) is connected by the elastic deformation of the connecting portion 310, which causes the groove 311 of the connecting portion 310 to fit with the flange 26 of the mounting side connecting portion 25 of the body ventilation device 2A(2). The blower control 303(3) and the body ventilation device 2A(2) are detachable.

[0211] Here, we will briefly explain the placement of the pockets 620 on the garment 600B. When the human body is exposed to a hot environment, there is a risk of heatstroke due to the heat, and it also suffers significant adverse effects on the autonomic nervous system. Therefore, as a preventative measure, it is essential to first cool the blood in the arteries that flow to the brain, and to promote sweating to maintain the normal function of thermoregulation.

[0212] To effectively cool the blood flowing to the brain, it is recommended to cool the arteries in the neck, armpits, and groin.

[0213] In the case of the neck, the carotid arteries are located not only near the hairline at the back of the neck, but especially on both sides of the throat. Cooling the area that touches the arteries with cold air or similar means cools the blood, and this cooled blood circulates throughout the body. This helps to lower body temperature.

[0214] Furthermore, the armpit is precisely where a thermometer is placed, and it is an area where arteries are located. The arteries in the armpit extend towards the arm, and when the blood in the arteries in the armpit and the arteries in the softer inner part of the upper arm is cooled, the cooled blood circulates throughout the body. This helps to lower body temperature.

[0215] Furthermore, exposing the armpits to cool air can provide a cooling sensation because the evaporative cooling from sweat in the armpits lowers the skin's surface temperature. In the case of the inner thigh, there is a large artery that runs towards the toes located in the inner third of the line connecting the front of the thigh, the hip bone, and the groin. When the blood in this large artery is cooled, the cooled blood circulates throughout the body. This helps to lower body temperature.

[0216] Based on these findings, in order to cool the arteries in the neck and armpits, and the arteries in the groin area as needed, pockets 620 are formed in the garment 600B in the areas corresponding to the neck and armpits, and the groin area, as shown in Figure 46.

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

[0218] <Embodiment 9> Next, the body ventilation device according to Embodiment 9 will be described using Figures 49 to 54. Compared to the body ventilation device mentioned as an example in the mounting location of the ventilation control device according to Embodiment 1, it differs in the structure of the housing and in having a variable airflow direction member.

[0219] In Embodiment 9, the explanation will focus on the parts that differ from Embodiments 1 to 8. The explanation of parts that are common with Embodiment 1 and the like will be simplified or omitted by using a symbol where the first digit is 2 and the last two digits are the same, for example, by changing only the first digit from 1 to 8 and keeping the last two digits the same, such as the internal space 10S in Embodiment 1 and the space 810S in Embodiment 9.

[0220] Figure 49 is a perspective view showing a body ventilation device according to Embodiment 9, showing the state before the variable airflow member is attached to the surrounding cutout in the first configuration, and Figure 50 shows the state after the variable airflow member is attached to the surrounding cutout in the first configuration. Figure 51 is a schematic diagram showing the airflow in the internal space of the body ventilation device, as seen from the line J-J in Figure 50. Figure 52 is a perspective view showing a body ventilation device according to Embodiment 9, showing the state before the variable airflow member is attached to the surrounding cutout in the second configuration, and showing the state after the variable airflow member is attached to the surrounding cutout in the second configuration. Figure 54 is a schematic diagram showing the airflow in the body ventilation device, as seen from the line K-K in Figure 53.

[0221] As shown in Figures 49 to 54, the body ventilation device 2E has a housing 810 with a different structure from the housing 10 of the body ventilation device 2 exemplified in Embodiment 1, and a variable airflow member 900. Since the body ventilation device 2E has the same configuration as the body ventilation device 2 except for the housing 810 and the variable airflow member 900, the description of the configuration other than the housing 810 and the variable airflow member 900 is omitted in Embodiment 9.

[0222] As shown in Figures 1 to 7, the body ventilation device 2E, like the body ventilation device 2, includes a Peltier element unit 30, a blower fan 35, a control unit 38, etc. The body ventilation device 2E also includes a housing 810 and a variable airflow member 900.

[0223] As shown in Figures 49 to 54, the housing 810 has an outer housing portion 811 in which an intake port 821 and an exhaust port 822 are formed, and an inner housing portion 812 which is butt-jointed with the outer housing portion 811 in an opposing position. The housing 810 has a space 810S. A supported portion 816 is formed in the inner housing portion 812.

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

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

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

[0227] The first side portion 813a extending along the X-axis and the second side portion 813b extending along the Z-axis share a connection point 814 where they are adjacent to each other at the corner of the housing 810. The housing 810, which forms the cover of the body ventilation device 2E, includes a surrounding cutout portion 815, as shown in Figures 49 to 52.

[0228] As shown in Figures 49 to 54, the enclosed cutout 815 is a portion of the space 810S that includes the air blowing region Q, which is the region from which the temperature-controlled air FL is blown out, and is an open section of the space 810S in a roughly L-shape. This enclosed cutout 815 is provided at the corner of the housing 810 where the connection point 814 between the first side portion 813a and the second side portion 813b is located.

[0229] Three engagement grooves 850 are formed on the end face of the first side portion 813a in the surrounding cutout portion 815. Similarly, three engagement grooves 850 are formed on the end face of the side end portion 811b in the second side portion 813b.

[0230] The wind direction variable member 900 consists of a base portion 910, an opening 921, a closing portion 922, an engaging piece portion 925, and a handle 926. The base portion 910 is formed in a roughly L-shape and plate-like form. One plate portion of the base portion 910 is the opening 921, and the other plate portion perpendicular to the first plate portion is the closing portion 922.

[0231] The opening 921 is a through-hole formed in such a manner that the temperature-controlled airflow FL can circulate to the outside. The plate portion containing the opening 921 is provided with an engaging piece 925 that can engage with the engaging groove 850. The engaging piece 925 protrudes from the end face of the plate portion toward the X-axis.

[0232] The closure portion 922 is a cover that blocks the flow of temperature-controlled air FL to the outside. The plate portion on which the closure portion 922 is located is provided with a handle 926 and an engaging piece 925. One engaging piece 925 is projected toward the Z-axis from the end face of the closure portion 922, and two pieces are arranged along the Y-axis.

[0233] The wind direction variable member 900 is positioned in the surrounding cutout 815 as part of the housing and attached to the housing 810. The wind direction variable member 900 can be attached to the surrounding cutout 815 in the first configuration and can be attached to the surrounding cutout 815 in the second configuration.

[0234] As shown in Figures 49 to 51, the first configuration is one in which the opening 921 of the wind direction variable member 900 is located on the first side portion 813a and the closing portion 922 of the wind direction variable member 900 is located on the second side portion 813b. As shown in Figures 52 to 54, the second configuration is one in which the opening 921 of the wind direction variable member 900 is located on the second side portion 813b and the closing portion 922 of the wind direction variable member 900 is located on the first side portion 813a.

[0235] In the first configuration, when attaching the variable airflow member 900 to the housing 810, the variable airflow member 900 is mounted to the housing 810 by engaging the two engaging pieces 925 on the closed portion 922 side of the variable airflow member 900 with the two engaging grooves 850 on both sides of the second side portion 813b, and then engaging the engaging piece 925 on the opening 921 side of the variable airflow member 900 with the two engaging grooves 850 on both sides of the first side portion 813a.

[0236] When the variable airflow member 900 is mounted on the housing 810 in the first configuration, as shown in Figure 51, the temperature-controlled airflow FL generated by the body ventilation device 2E is blown out from the opening 921 located on the inner housing portion 812 (first side portion 813a) side of the body ventilation device 2E.

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

[0238] When the variable airflow member 900 is mounted on the housing 810 in the second configuration, as shown in Figure 54, the temperature-controlled airflow FL generated by the body ventilation device 2E is blown out from the opening 921 located on the second side 813b of the body ventilation device 2E.

[0239] <Embodiment 10> Next, a body ventilation device with a ventilation control device according to Embodiment 10 will be described with reference to Figure 55.

[0240] In Embodiment 10, the explanation will focus on the parts that differ from Embodiment 9, and the explanation of parts common to Embodiment 9 will be simplified or omitted using the same reference numerals.

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

[0242] The body-use air blower 2E is configured such that a flange corresponding to the flange 26 of the mounting-side connection portion 25 of the body-use air blower 2 is formed in the opening 921 of the airflow direction variable member 900. Furthermore, as shown in Figure 55, the opening 921 of the airflow direction variable member 900 is formed in a manner that allows it to be attached to and detached from the connection portion of the air blower control device. Specifically, the air blower control device 403A(3) has a groove in the connection portion, similar to the connection portion 110 of the air blower control device 103(3) according to Embodiment 1, instead of the fixing portion 450 of the air blower control device 403.

[0243] In the body blower with air blower control device 1Xu (1X), the air blower control device 403A (3) and the body blower 2E are attached in a manner that allows them to be attached and detached by fitting together a groove in the connecting portion formed in the air blower control device 403 (3) with a flange provided in the opening 921 of the body blower 2E.

[0244] <Embodiment 11> Next, a body ventilation device with a ventilation control device according to Embodiment 11 will be described with reference to Figure 56.

[0245] Embodiment 11 will primarily describe the parts that differ from Embodiments 91 and 0, while the descriptions of parts common to Embodiments 9 and 10 will be simplified or omitted using the same reference numerals.

[0246] Figure 56 is a perspective view showing a body ventilation device with an air blower control according to Embodiment 10, in which the air blower control according to Embodiment 3 is attached to the body ventilation device shown in Figure 53. As shown in Figure 56, the body ventilation device with an air blower control 1Xv (1X) consists of a body ventilation device 2E according to Embodiment 9 and an air blower control 303 (3) according to Embodiment 3.

[0247] Similar to the body ventilation device with airflow control 1Xu (1X), the body ventilation device with airflow control 1Xv (1X) also has a flange corresponding to the flange 26 of the mounting-side connection portion 25 on the body ventilation device 2A at the opening 921 of the variable airflow member 900. In the body ventilation device with airflow control 1Xv (1X), the airflow control 303 (3) is attached to the body ventilation device 2E in a manner that allows it to be attached and detached.

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

[0249] That is, the body blower 2 etc (2) configured in the body blower with airflow control device according to Embodiment 12 includes a housing 10, as detailed in Embodiments 1 to 5. The housing 10 consists of an outer housing portion 11 and an inner housing portion 12A (12) separately. Alternatively, the housing 10 consists of an outer housing portion 11 and an inner housing portion 12B (12) separately. Alternatively, the housing 10 consists of an outer housing portion 11 and an inner housing portion 12C (12) separately. Alternatively, the housing 10 consists of an outer housing portion 11 and an inner housing portion 12D (12) separately.

[0250] On the other hand, the body ventilation device 2 includes a Peltier element unit 30 including a Peltier element 31, a heat sink 32 including a blowing-side heat sink 32A and an exhaust-side heat sink 32B, and a blower fan 35. The body ventilation device 2 is used by being worn on the body, and blows temperature-controlled air FL from the air outlet 23 towards the body. The airflow control device according to Embodiments 1 to 4 is attached to such a body ventilation device 2.

[0251] Let me explain in detail. The body ventilation device with a blower control device according to Embodiment 12 is, as Embodiment 1, a first embodiment device consisting of a body ventilation device 2A (2) and a blower control device 103A (3), as shown in Figures 1 and 9, etc.

[0252] Furthermore, the body ventilation device with a ventilation control device according to Embodiment 12 is, as Embodiment 2, a second embodiment of the device consisting of a body ventilation device 2A (2) and a ventilation control device 103B (3), as shown in Figures 1 and 13, etc., in Embodiment 1.

[0253] Furthermore, the body ventilation device with a ventilation control device according to Embodiment 12 is, as Embodiment 3, a third embodiment of the device consisting of a body ventilation device 2A (2) and a ventilation control device 203A (3), as shown in Figures 1 and 14, etc., in Embodiment 2.

[0254] Furthermore, the body ventilation device with a blower control device according to Embodiment 12 is, as Embodiment 4, a fourth embodiment of the device consisting of a body ventilation device 2A (2) and a blower control device 203B (3), as shown in Figures 1 and 18, etc., in Embodiment 2.

[0255] Furthermore, the body ventilation device with a ventilation control device according to Embodiment 12 is, as Embodiment 5, a fifth embodiment of the device consisting of a body ventilation device 2B (2) and a ventilation control device 303 (3), as shown in Figures 23 and 24, etc., in Embodiment 3.

[0256] Furthermore, the body ventilation device with a ventilation control device according to Embodiment 12 is, as Embodiment 6, a sixth embodiment of the device consisting of a body ventilation device 2C (2) and a ventilation control device 403 (3), as shown in Figures 28 and 29, etc., in Embodiment 4.

[0257] Next, the operation and effects of the air blower control device, the body air blower, and the body air blower with air blower control device according to this embodiment will be described.

[0258] The air blower control device 3 (103A, 103B, 103A, 103B, 303, 403) according to these embodiments 1 to 8 and 10 to 12 has an outer housing portion 11 with an intake port 21 and an exhaust port 22 formed therein, and an inner housing portion 12 (12A, 12B, 12C, 12D) that is butted against and connected to the outer housing portion 11, and an air blower port 23 provided therein, a Peltier element 31 disposed inside the housing 10, and an air blower side heat sink 32A (cooling fin or heat dissipation fin) formed on one surface 31a of the Peltier element 31 The body ventilation devices 2A, 2B, 2C, and 2D (2) are attached to the body ventilation device 2A, 2B, 2C, and 2D (2). The body ventilation device 2A is attached to the body ventilation device 2 and controls the flow of the temperature-controlled air FL, which is either cold air CF that has passed through the air-blowing heat sink 32A or warm air HF that has passed through the heat-blowing fins. The ventilation control device 3 is attached to the body ventilation device 2 and controls the flow of the temperature-controlled air FL. The air blower control device 3 includes a hollow flow path FP through which temperature-controlled air FL can flow, connecting parts 110, 210, 310, 410 formed to be detachably attached to the air outlet 23 by at least one fixing means among fitting, fastening, and engaging, introduction parts 120, 220, 320, 420 that take in temperature-controlled air FL supplied from the air outlet 23 into the flow path FP from the inlet 121 when the connecting parts 110, 210, 310, 410 are mounted on the housing 10, and outlet parts 130, 230, 330, 430 that extend from the introduction parts 120, 220, 320, 420 to the outlet 131 of the flow path FP. In the outlet-side distribution path FPe, which passes through the discharge sections 130, 230, 330, and 430, the cross-sectional area S1 on the outlet side 131 is the same size as, or smaller than, that on the inlet side 120, 220, 320, and 420.

[0259] This feature allows the temperature-controlled airflow FL generated by the body air blower 2 to be efficiently blown over a wide area along the body surface towards the desired body part of the user HM by the airflow control device 3.

[0260] In particular, if the air blower control devices 3, such as air blower control devices 103A, 103B, 203A, 203B, and 303, are configured in multiple types, with the specifications of the connection parts 110, 210, and 310 being standardized, while the rest of the device has different structures, shapes, and other specifications, then multiple types of air blower control devices 3 can be combined and all can be attached to the body ventilation device 2. Therefore, multiple types of air blower control devices 3 can be attached to the same body ventilation device 2 with interchangeability.

[0261] Therefore, the user HM can select a blower control device that suits their needs from among several types of blower control devices 103A, 103B, 203A, 203B, and 303(3) and attach it to their personal blower device 2.

[0262] Furthermore, even if the body part of the user HM that receives the temperature-controlled airflow FL changes, the airflow control device 3 can be replaced as needed from among the multiple types of airflow control devices 103A, 103B, 203A, 203B, 303(3), for example, by replacing airflow control device 103A with airflow control device 203A, to accommodate the body part that receives the temperature-controlled airflow FL. Therefore, the airflow control device 3 can widely meet the needs of the user HM.

[0263] Furthermore, the air blower control device 3 according to these embodiments 1 to 4 is characterized in that the inlet sections 120, 220, 320, and 420 are formed in a shape that narrows towards the outlet sections 131, 231, 331, and 431, so that the cross-sectional area S2 on the outlet section 131, 231, 331, and 431 is smaller than that on the inlet section 120, 220, 320, and 420 side.

[0264] This feature allows the temperature-controlled air FL supplied from the body ventilation device 2 to be blown out from the outlets 131, 231, 331, and 431 at a higher airflow speed, enabling air to be blown over a wider area along the user's body surface, including the arms, legs, upper body, neck, and head. Furthermore, the ventilation control device 3 has a shape that narrows towards the outlets 131, 231, 331, and 431. As a result, the air outlets 130, 230, 330, and 430 can be easily placed in narrow spaces, such as the narrow space between the user's body and the clothing being worn, or the narrow space between the user's head and the helmet shell when wearing a helmet.

[0265] Furthermore, the air blower control device 303(3) according to this third embodiment is characterized in that the introduction section 320 has a flow guide section 325 formed in the flow path FP that guides the flow of the temperature-controlled air FL taken in toward the discharge section 330.

[0266] This feature allows the temperature-controlled air FL, taken in by the inlet 320, to flow along the inner wall of the flow path FP to the outlet 330, thereby suppressing the generation of excessive turbulence caused by a decrease in flow velocity and pressure loss in the circulating temperature-controlled air FL. As a result, the temperature-controlled air FL, within the flow path FP, flows from the inlet 320 to the outlet 331 of the outlet 330 with minimal decrease in air velocity, and is blown out to the outside in a state close to laminar flow.

[0267] Furthermore, the air blower control devices 103, 203, 303(3) according to these embodiments 1 to 3 are characterized in that the connecting parts 110, 210, 310 are made of a flexible material, and can be connected to the body blower devices 2A, 2B(2) by elastically deforming the connecting parts 110, 210, 310 and attaching them to the air outlet 23.

[0268] This feature allows both the body ventilation device 2 and the ventilation control device 3 to be constructed with simple structures, making them inexpensive to manufacture. Moreover, the user HM can easily attach and detach the ventilation control device 3 and the body ventilation device 2.

[0269] In particular, when the connecting parts 110, 210, and 310 are made of, for example, silicone rubber, rubber, etc., when the flange 26 of the mounting-side connecting part 25 of the body ventilation device 2 is fitted and connected to the groove 111 of the connecting part 110, etc., the airtightness at the joint between the ventilation control device 3 and the body ventilation device 2 is improved. As a result, the temperature-controlled air FL supplied from the body ventilation device 2 can be delivered to the introduction part 120 of the ventilation control device 3 while preventing leakage at the joint.

[0270] Furthermore, the air blower control device 3 according to this fourth embodiment is characterized in that, when connected to the body blower device 2C(2), a fixing portion 450 or the like is formed in the air outlet 23 to fix the connecting portion 410.

[0271] This feature allows the body ventilation device 2C(2) to be connected to and disconnected from the ventilation control device 3 at the fixing part 450, so it can be used differently depending on whether the ventilation control device 3 is needed or not.

[0272] In particular, if the user HM is a worker who works in a dangerous environment, such as a civil engineering construction site or a factory plant facility, external forces and impacts associated with the work may significantly affect the air blower control device 403(3) and the body-type air blower device 2C(2) when the user HM is wearing the body-type air blower device 2C(2) with the air blower control device 403(3) attached while working.

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

[0274] Furthermore, the air blower control devices 103A and 203B (3) according to these embodiments 1 and 2 are characterized by being equipped with flaps 140 and 240 that change the direction of the temperature-controlled airflow FL circulating in the flow path FP.

[0275] This feature allows the airflow control device 103A(3) to, even when the user HM positions the outlet 131 of the air outlet 130 toward a desired part of the body that wants to receive the temperature-controlled airflow FL, to also deliver the temperature-controlled airflow FL to another part of the body that also wants to receive the temperature-controlled airflow FL, at the user HM's discretion. The same applies to the airflow control device 203B(3).

[0276] In other words, when the flap 140 or the like opens, the temperature-controlled air FL that flows into the inlet 121 or the like is divided into a main flow that goes to the outside from the outlet 131 or the like and a tributary flow that goes to the outside from an opening 142 or the like which is facing a different direction from the outlet 131 or the like, and blows out. Conversely, when the flap 140 or the like closes, the temperature-controlled air FL is blown out to the outside only by the main flow from the outlet 131 or the like.

[0277] Furthermore, the air blower control device 3 according to these two and three embodiments is characterized in that the air blower control device 203, 303 includes at least two outlet sections 230, 330, and the first outlet section 230a and the second outlet section 230b, and the first outlet section 330a and the second outlet section 330b are formed in such a manner that they branch and bend in different directions with respect to the introduction sections 220, 320, and the first outlet section 230a and the second outlet section 230b are arranged on opposite sides of each other with respect to the Y-axis, or are arranged in a substantially V-shape.

[0278] This feature allows the airflow control devices 203 and 303 to blow air over a wider area onto the body parts of the user HM that wish to receive the temperature-controlled airflow FL. Moreover, the temperature-controlled airflow FL does not directly hit the user HM's body, but spreads widely from both the first outlet 230a and the second outlet 230b, blowing air along the surface of the body, so the user HM can feel comfortable.

[0279] Similarly, the temperature-controlled airflow FL does not directly hit the user's body, but spreads widely from both the first outlet 330a and the second outlet 330b, blowing air along the surface of the body, so that the user can feel comfortable.

[0280] Furthermore, the air blower control device 3 according to this fourth embodiment is characterized in that the air blower control device 403 includes one outlet section 430, and the outlet section 430 is formed in a manner that is bent in a substantially J-shape toward one side in the H-axis direction with respect to the introduction section 410.

[0281] This feature allows the outlet 431 of the air outlet 430 to be positioned so as not to face the user's body. As a result, the temperature-controlled air FL supplied from the body ventilation device 2 does not directly hit the user's body, but can be blown locally along the body surface towards the part of the user's body that wants to receive the airflow.

[0282] In other words, when the temperature-controlled airflow FL is cool air CF, the user HM will not be excessively cooled by the blown cool air CF (temperature-controlled airflow FL) and will not feel uncomfortable. Also, when the temperature-controlled airflow FL is warm air HF, the user HM can be prevented from being excessively heated by the blown warm air HF (temperature-controlled airflow FL).

[0283] Furthermore, in the air blower control device 403(3) according to this fourth embodiment, the blower portion 430 has a wall member 432 that surrounds the flow path FP and a projection 433 that protrudes from the wall member 432, and when the connecting portion 410 is attached to the body blower 2, the projection 433 is formed on the portion of the wall member 432 that faces the inner housing portion 12(12) of the body blower 2C(2).

[0284] This feature allows the multiple protrusions 433 to function as ribs to reinforce the wall member 432. These multiple protrusions 433 enable the air outlet section 430 to be constructed with greater rigidity.

[0285] In particular, when the user HM is a worker who works in dangerous work environments such as civil engineering sites or factory plant facilities, the body-type ventilation device 2C(2) with the ventilation control device 403(3) attached may be used attached to work clothes. In such cases, the ventilation control device 403(3) is designed to be highly resistant to external impacts caused by work movements, and is therefore less likely to be damaged.

[0286] Furthermore, the body ventilation device 1 with a ventilation control device according to this embodiment 12 has an outer housing portion 11 having an intake port 21 and an exhaust port 22, and an inner housing portion 12 (12A, 12B, 12C, 12D) that are butt-jointed and connected to the outer housing portion 11 in an opposing position, and a housing 10 having a ventilation port 23, a Peltier element 31 disposed inside the housing 10, a ventilation-side heat sink 32A (either cooling fins or heat dissipation fins) formed on one surface 31a of the Peltier element 31, and an exhaust-side heat sink 32B (heat dissipation fins) formed on the other surface 31b opposite to the surface 31a. The body ventilation device 2 (2A, 2B, 2C, 2D) is equipped with either a cooling fin or a cooling fin, and a blower fan 35 that introduces air from an air intake 21 and sends air to the blower-side heat sink 32A and the exhaust-side heat sink 32B. The device is worn on the body of the user HM, and temperature-controlled air FL, which is either cold air CF that has passed through the blower-side heat sink 32A or warm air HF that has passed through the heat dissipation fin, is blown out from an air outlet 23. The blower control device 3 (103A, 103B, 103A, 103B, 303, 403) is detachably attached to the housing 10 of the body ventilation device 2.

[0287] Due to this feature, the temperature-controlled airflow FL is blown along the surface of the user's body by the airflow control device 3, rather than directly hitting the user's body, allowing the user to feel comfortable. In addition, the airflow control device 3 can efficiently blow the temperature-controlled airflow FL over a wide area along the surface of the user's body, towards the part of the user's body that wants to receive it.

[0288] Furthermore, the body ventilation device 2E according to this embodiment 9 comprises a housing 810 having an outer housing portion 811 with an intake port 821 and an exhaust port 822 formed therein, and an inner housing portion 812 that is butted against and connected to the outer housing portion 811, and also having an air outlet 823, a Peltier element 31 disposed inside the housing 810, a blower-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 surface 31a, and a blower fan 35 that introduces air from the intake port 821 and sends air to the blower-side heat sink 32A and the exhaust-side heat sink 32B, and is attached to the body of the user HM, and cool air CF that has passed through the blower-side heat sink 32A In a body blower in which temperature-controlled air FL, which is either the warm air HF that has passed through the heat dissipation fins or the temperature-controlled air FL that has passed through the heat dissipation fins, is blown out from the blowing area Q, the body blower in which a variable airflow member 900 is provided with an opening 921 formed in such a manner that the temperature-controlled air FL can flow to the outside and a closing part 922 that blocks the flow of the temperature-controlled air FL to the outside, the opening 900 is arranged in different directions from the opening, the housing 810 which forms the cover of the body blower in 2E includes a surrounding gap 815 in which a part of the space 810S including the blowing area Q is left open, the surrounding gap 815 is provided at the connection point 814 between a first side part 813a and a second side part 813b adjacent to the first side part 813a in a different direction from the housing 810, and the variable airflow member 900 forms part of the housing and is attached to the surrounding gap 815.

[0289] This feature allows the user HM to freely select the direction of the temperature-controlled airflow FL using the airflow direction variable member 900, according to their intended use. Therefore, when a user HM uses the body ventilation device 2E they possess, the range of options for the installation configuration of the body ventilation device 2E is wider, and the degree of freedom in how the body ventilation device 2E is used is high.

[0290] Specifically, regardless of how the user HM carries the body-type air blower 2E, such as by placing it in a clothing pocket, hanging it from the upper body, or attaching it to a belt or tool, the body-type air blower 2E can be flexibly adapted by adjusting the direction of the temperature-controlled airflow FL using the airflow direction variable member 900 to suit the method of carrying. Therefore, the body-type air blower 2E is easy to use.

[0291] Furthermore, in the body ventilation device 1X (1Xu1Xv) with a ventilation control device according to these embodiments 10 and 11, the housing 810 has an outer housing portion 811 in which an intake port 821 and an exhaust port 822 are formed, and an inner housing portion 812 which is abutted and connected to the outer housing portion 811 in an opposing position, and an air outlet 823 is provided, a Peltier element 31 disposed inside the housing 810, and a ventilation-side heat sink 32A (cold) formed on one surface 31a of the Peltier element 31. The system includes either a cooling fin or a heat dissipation fin, an exhaust-side heat sink 32B (either a heat dissipation fin or a cooling fin) formed on the other side 31b opposite to one side 31a, and a blower fan 35 that introduces air from the intake port 821 and blows air to the blower-side heat sink 32A and the exhaust-side heat sink 32B, and is worn on the body of the user HM, and the temperature of the cold air CF that has passed through the blower-side heat sink 32A or the warm air HF that has passed through the heat dissipation fin is A body-use air blower that blows out temperature-controlled air FL from a blowing area Q, comprising a variable airflow member 900 having an opening 921 formed in such a manner that the temperature-controlled air FL can flow to the outside, and a closing part 922 that blocks the flow of the temperature-controlled air FL to the outside, arranged in different directions from each other, the housing 810 which forms the cover of the body-use air blower 2E includes a surrounding gap 815 in which a part of the space 810S including the blowing area Q is open, and the surrounding gap 815 is a housing The wind direction variable member 900 is provided at the connection point 814 between the first side portion 813a and the second side portion 813b adjacent to the first side portion 813a in a different direction from the first side portion 813a. The wind direction variable member 900 is part of the housing and is attached to the surrounding cutout portion 815. The wind control devices 3 (103A, 103B, 103A, 103B, 303, 403) are detachably attached to the opening 921 of the wind direction variable member 900.

[0292] Due to this feature, the main body of the body ventilation device 1X with a blower control is the body ventilation device 2E, and the body ventilation device 2E can freely select the direction of the temperature-controlled airflow FL to be blown using the airflow direction variable member 900, according to the user HM's needs. Therefore, when a user HM uses the body ventilation device 2E they possess, the range of options for the installation configuration of the body ventilation device 2E is wider, and the degree of freedom in how the body ventilation device 2E is used is high.

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

[0294] In addition, even if the user HM uses the body ventilation device 1X with a ventilation control in various ways, the temperature-controlled airflow FL is blown along the surface of the body by the ventilation control 3 without directly hitting the user HM's body, so the user HM can feel comfortable. Furthermore, the ventilation control 3 can efficiently blow air along the surface of the body over a wide area towards the body parts of the user HM that wish to receive the temperature-controlled airflow FL.

[0295] Furthermore, in the body-use air blower 1X with air blower control device according to this embodiment 9, the airflow direction variable member 900 is formed in such a manner that it can be reversibly attached to the surrounding cutout portion 815 in either a first configuration in which the opening 921 is located on the first side portion 813a and the closing portion 922 is located on the second side portion 813b, or in a second configuration in which the opening 921 is located on the second side portion 813b and the closing portion 922 is located on the first side portion 813a.

[0296] This feature allows the body-use air blower 1 with air blower control to change the direction of the opening 921 from which the temperature-controlled air FL is blown out, according to the position of the body part of the user HM that wants to receive the temperature-controlled air FL.

[0297] Furthermore, in the body blower 1 with a blower control device according to this embodiment 12, the inner housing portion 12 (12A, 12B, 12C, 12D) includes a fixed portion 50 formed to be engageable with a fixing portion 450 etc. on the blower control device 3, the housing 10 is composed of the inner housing portion 12 and the outer housing portion 11 as separate parts, and by engaging the fixing portion 450 etc. of the blower control device 3 with the fixed portion 50 of the inner housing portion 12, the air outlet 23 of the body blower 2 which forms the main body of the body blower 2 with a blower control device is connected to the connection portions 110, 210, 310, 410 of the blower control device 3.

[0298] This feature allows the body ventilation device 1 with a blower control to attach to the air outlet 23 of the body ventilation device 2 a blower control selected as needed from among several types of blower control devices 103A, 103B, 203A, 203B, 303, 403 (3).

[0299] In particular, as with the air blower control devices 103A, etc. (air blower control devices 103A, 103B, 203A, 203B, 303), the air blower control devices 103A, etc. are connected to the air outlet 23 of the body blower 2A (2) by a fixing means that involves fitting the groove 111 of the elastically deformed connecting portion 110 with the flange 26 of the mounting side connecting portion 25 of the body blower 2A. On the other hand, the air blower control device 403 is connected to and mounted on the body blower 2C (2) by a fixing means that involves engaging the engaging piece 451 of the fixing portion 450 with the engaging groove 51 of the fixed portion 50 of the inner housing portion 12C, and a fixing means that involves screw fastening between the fixing portion 450 and the fixed portion 50.

[0300] Even when the fixing means between the air blower control device 3 and the body blower device 2 differs, such as when the air blower control device 103A uses fitting as the fixing means, and the air blower control device 403 uses engagement and screw fastening as the fixing means, the outer housing portion 11 can be common to both the body blower device 2A(2) and the body blower device 2C(2) in the housing 10.

[0301] Therefore, in the housing 10, by simply replacing the inner housing portion that connects to the outer housing portion 11 with an inner housing portion 12 that corresponds to the fixing means of the blower control device 3 to be attached, such as by exchanging the inner housing portion 12A (12) on the body blower device 2A (2) side with the inner housing portion 12C (12) of the body blower device 2C (2), the user HM can select a blower control device that suits their needs from among several types of blower control devices 103A, 103B, 103A, 103B, 303 (3) and attach it to their body blower device 2.

[0302] In other words, even if the body part of the user HM that receives the temperature-controlled airflow FL changes, the airflow control device 3 can be replaced as needed from among the multiple types of airflow control devices 103A, 103B, 103A, 103B, 303(3) with the airflow control device that is compatible with the body part that receives the temperature-controlled airflow FL. Therefore, the airflow control device 3 can widely meet the needs of the user HM.

[0303] Furthermore, the body-use air blowers 1 and 1X with air blower control devices according to these embodiments 10 and 11 are characterized in that the opening 921 of the variable airflow member 900 is formed in a manner that allows it to be attached to and detached from the connection portions 110, 210, 310, and 410 of the air blower control device 3.

[0304] This feature allows the user HM to select the arrangement of the variable airflow member 900 relative to the enclosed gap 815 from a first arrangement and a second arrangement each time the body-use air blower 1 with airflow control device is used, according to its intended use. This makes it easy to change the direction of the temperature-controlled airflow FL being blown.

[0305] Furthermore, the body ventilation device 1A(1) with a ventilation control device according to this 5th embodiment is characterized by having a helmet mounting portion 550 that can be attached to the helmet shell 571 of the helmet 570.

[0306] This feature allows the user HM to integrate the body ventilation device 1A with the airflow control device with the helmet 570.

[0307] Furthermore, in the body-use air blower with air blower control device 1A(1) according to this 5th embodiment, the inner housing portion 12 is an inner housing portion 12D including a helmet mounting portion 550 and a retaining guide portion 510 that is detachably formed, and the housing 10 is composed of an outer housing portion 11 and an inner housing portion 12D.

[0308] This feature allows the body-mounted ventilation device 1A(1) with airflow control to be used in different ways depending on whether it is attached to the helmet 570 or not. When the body-mounted ventilation device 1A with airflow control is attached to the helmet 570, the temperature-controlled airflow FL is mainly cool air CF.

[0309] When a user HM uses a helmet 570 equipped with a body ventilation device 1A that blows out cool air CF, the body ventilation device 1A with the ventilation device can blow temperature-controlled air FL over the head of the user HM wearing the helmet 570 and around them within the helmet's internal space 570S. As a result, the user HM wearing the helmet 570 can experience comfort.

[0310] In other words, for example, at construction sites or factory plant facilities, where work is inherently dangerous, workers generally wear heavy-duty work clothes and helmets to protect themselves from danger. When such sites are exposed to the scorching sun and humid weather conditions, the necks of workers and the tops of their heads inside their helmets become stuffy due to the lack of ventilation. As a result, workers feel uncomfortable due to this stuffiness. This phenomenon occurs frequently.

[0311] Therefore, by having a user HM use a helmet 570 equipped with a body-type air blower with air blower control device 1A(1), the user HM can receive cool air CF (temperature-controlled air FL) in the stuffy space inside the helmet 570S, even while wearing work clothes and the helmet 570.

[0312] In particular, as shown in Figures 34, 35, and 37, in the stuffy helmet interior space 570S, cool air CF (temperature-controlled air FL) is blown in at different locations, such as around the neck, in addition to above and around the head, from the outlet 131 of the blower unit 130 and the opening 142 created by opening the flap 140. Therefore, the user HM wearing the helmet 570 can obtain comfort from the cool air CF (temperature-controlled air FL) blown out from the body ventilation device 1A with a ventilation control. The body ventilation device 1A with a ventilation control can, of course, also change the temperature-controlled air FL to warm air HF.

[0313] Furthermore, the body-use air blower with air blower control device (1), 1Xu (1X) according to this embodiment 6, 10 is characterized by having a garment attachment part 60 that can be attached to a garment 600.

[0314] This feature allows the user HM to integrate the body-mounted ventilation device 1 with the clothing 600 they are wearing.

[0315] Furthermore, in the body ventilation devices 1C(1) and 1Xu(1X) with air blower control according to these embodiments 6 and 10, the garment attachment portion 60 is characterized in that it is a gap formed between the body ventilation device 2C, which forms the main body of the body ventilation device with air blower control, and the air blower control 403.

[0316] This feature allows the user HM to easily fix and attach the body-mounted air blower 1C to the garment 600 by simply inserting the collar 610 and sleeves of the garment 600, as well as the placket, cuffs, collar, front and back edges of a dress shirt, etc., into the garment attachment section 60.

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

[0318] For example, in the air blower control device according to this disclosure, the tip portion of the blowing section, including the outlet, may be formed to be expandable and retractable, for example, by a bellows structure.

[0319] Furthermore, the air blower control device according to this disclosure may be configured such that the entire blowing section, or the tip of the blowing section including the outlet, is made of a flexible material, and the direction in which the air blows out after temperature adjustment can be freely varied.

[0320] Furthermore, in Embodiment 8, as shown in Figure 46, pockets 620 are placed on the back and near the sides of the garment 600B, and each pocket 620 houses a body ventilation device 1C(1) with a ventilation control device. However, Figure 46 is illustrated primarily for ease of viewing.

[0321] Therefore, the position of the body-use air blower 1E with air blower control device to be placed on the garment is not precisely shown in Figure 46, nor is it limited to the position shown in Figure 46.

[0322] In other words, the body-mounted air blower 1, which is worn in a pocket and has an air blower control device, is positioned to cool the blood in the arteries passing near the neck and the armpits and flanks, areas prone to excessive sweating, and to cool the parts of the body that are prone to sweating. It is positioned in a way that takes into account the ease of movement of the person actually wearing the garment 600B.

[0323] Furthermore, in Embodiment 1, the external shape of the body ventilation device 2A is as shown in Figures 1 to 6, but the external shape of the body ventilation device is not limited to this embodiment and can be changed as appropriate.
