Description

[Technical Field]

[0001] This invention relates to an air-blowing cooling system that uses an air blower to cool the body surface by blowing air. More specifically, it relates to an air-blowing cooling system that is more efficient at cooling the body than conventional systems and has a structure with a high degree of design freedom. [Background technology]

[0002] BACKGROUND ART Conventionally, as in Patent Document 1, a ventilation cooling system has been known in which a fan is attached to clothing, air is drawn in from the outside, and air is blown out to the inside.

[0003] In conventional ventilation cooling systems, a fan draws in air to create positive pressure inside the garment, and then circulates the air throughout the garment to cool the body. Because the inside of the garment is under positive pressure, the air that absorbs body heat is naturally expelled through gaps between the body and the garment, such as the sleeves, hem, and collar.

[0004] However, due to the structure of conventional ventilation cooling systems, it was necessary to maintain sufficient positive pressure inside the clothing to circulate the air. Clothing made of materials that are prone to air leakage does not allow for proper air flow inside the clothing, and cooling performance is not fully realized. For this reason, it was necessary to use materials that are less prone to air leakage and to increase the airtightness inside the clothing.

[0005] This required various countermeasures to be implemented at the design stage, limiting the design freedom of the product. Even in products designed to ensure adequate airflow by installing spacers to rectify the air inside the garment or by installing guide parts for the airflow path, if the gaps in the garment that allow the air to pass through are blocked by the user's movements, exhaust becomes insufficient and the amount of air circulating inside the garment decreases. This reduced air circulation not only prevents the body from being properly cooled, but also puts excessive strain on the motor if the internal pressure increases abnormally due to insufficient exhaust, increasing the risk of blower failure.

[0006] Furthermore, clothing made with highly airtight materials and structures to maintain positive pressure would inflate like a balloon from the torso to the tips of the sleeves due to the intake air, ruining the aesthetic appearance of the garment when worn. Furthermore, the inflated garment not only unnecessarily restricted visibility of the feet and hands, but also created air resistance that hindered movement during work, posing a problem.

[0007] In this regard, a product has been proposed that includes an inner garment that guides air (see, for example, Patent Document 2), but this merely changes the guide parts of the flow path to the inner garment, and does not provide a fundamental solution that resolves all of the following issues: low design freedom as a product; insufficient cooling of the body when gaps in the clothing are blocked; increased risk of blower failure due to insufficient exhaust; poor aesthetics when worn; and interference with movement during work.

[0009] The purpose of this invention is to solve the above problems and provide a ventilation cooling system that has sufficient cooling performance and durability while maintaining an aesthetic appearance during use. [Means for solving the problem]

[0010] As a technical means adopted by the present invention to achieve the above-mentioned object, the invention described in claim 1 is a blowing cooling system comprising a base member, a mounting hole provided in the base member, and a blower attached to the mounting hole, the blower having an intake port and an outlet port, the outlet port being provided above and perpendicular to the intake port.

[0011] The invention described in claim 2 is a blowing cooling system having the features described in claim 1, characterized in that the blower is removably clamped between a mounting portion provided around the intake port and a ring-shaped fixing member that holds the base member.

[0012] The invention described in claim 3 is a blowing cooling system having the features described in claim 1 or claim 2, characterized in that the base member is a hooded garment, and the blower is attached so that the intake port is on the outer side of the hooded garment and the exhaust port is on the inner side of the hooded garment and facing the hood portion.

[0013] The invention described in claim 4 is a blowing cooling system having the features described in claim 1 or claim 2, characterized in that the base member is a backpack, the blower is attached so that the intake port is located on the outer surface of the backpack, and the outlet port is located toward the top of the backpack. [Effects of the Invention]

[0014] According to the invention of claim 1, the device comprises a base member, a mounting hole provided in the base member, and a blower attached to the mounting hole. The blower has an inlet and an outlet, with the outlet located above and perpendicular to the inlet. Even if the base member does not have an airflow path or does not have a component that creates a flow path, as long as the outlet of the blower is positioned perpendicular to the inlet, the airflow from the blower is directional and can be rectified. Therefore, the blown air removes heat from the user's body surface and then smoothly leaves the user's body surface. This allows the user to experience a sufficient cooling effect. Furthermore, structural restrictions on the material of the base member are relaxed, eliminating the need for detailed design to ensure an airflow path, thereby improving design freedom.

[0015] According to the invention of claim 2, the blower is detachably fixed by clamping the base member between a mounting part provided around the suction port and a ring-shaped fixing member. This improves maintainability and simplifies repairs and replacements of the blower and cleaning of the base member.

[0016] According to the invention of claim 3, the base member is a hooded garment, and the blower is attached so that the inlet is on the outer surface of the hooded garment and the outlet is on the inner surface of the hooded garment, facing the hood. Even if the base member or other components that create an air flow path are not included, if the outlet of the blower is positioned perpendicular to the inlet, the directionality of the airflow from the blower can be achieved, thereby rectifying the flow of the blown air. As a result, the blown air absorbs heat from the user's body surface and then smoothly leaves the user's body surface. At this time, the air blown from the blower, which is attached so that the outlet is positioned facing the hood, flows along the inner side of the hooded garment toward the hood and is then exhausted through the hood. This efficiently cools the user's neck and back of the head. Furthermore, by blowing outside air upward from the outlet perpendicular to the inlet, the air is blown along the back, neck, and back of the head, preventing direct airflow from hitting the user. Therefore, the user is less likely to feel temperature differences depending on the location on the skin surface, making it more comfortable.

[0017] According to the invention of claim 4, the base member is a backpack, and the blower is attached so that the inlet is located on the outer surface of the backpack and the outlet is located toward the top of the backpack. Even if the base member does not have a base member that serves as an air flow path or a part that creates a flow path, if the outlet of the blower is positioned perpendicular to the inlet, the air flow from the blower becomes directional and the blown air flow can be rectified, thereby achieving a cooling effect even when the base member is a backpack. By using the base member as a backpack, users can easily attach, detach, and carry the air-blowing cooling system. In addition, the high degree of design freedom improves design, making the air-blowing cooling system easy to use in everyday life. [Brief explanation of the drawings]

[0019] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. In this specification and drawings, components having substantially the same functional configurations are designated by the same reference numerals, and redundant explanations will be omitted.

[0020] An embodiment of the present invention will be described below with reference to the drawings. Figures 1 to 7 show an example of a blow-air cooling system according to the present invention. The blow-air cooling system comprises a base member 2, a mounting hole 3 provided in the base member 2, and a blower 1 attached to the mounting hole 3. The blower 1 has an intake port 4 and an outlet port 5, and the outlet port 5 is provided above and perpendicular to the intake port 4.

[0021] Specifically, the air inlet 4 of the blower 1 is provided facing the base member, and the blower 1 is detachably fixed to the base member 2 by clamping the base member 2 between a mounting portion 6 provided around the air inlet 4 and a ring-shaped fixing member 7 attached opposite the mounting portion 6. The air outlet 5 of the blower 1 is provided above and parallel to the base member 2, and the air flows at the air inlet 4 and the air outlet 5 are perpendicular to each other inside the blower. The blower 1 has a fan 8, a shaft 9 that serves as the shaft of the fan 8, and a motor 10 that rotates the fan 8 via the shaft 9.

[0022] When fan 8 rotates, external air is drawn into blower 1 through intake port 4, creating an air flow parallel to the axial direction of shaft 9. The air drawn in by fan 8 is sent in the direction of outlet 5, which is perpendicular to the axial direction of shaft 9. The sent air is blown out of blower 1 from outlet 5, creating an air flow parallel to base member 2.

[0023] According to the embodiment based on the above drawings, blower 1 has intake port 4 and outlet port 5, and outlet port 5 is provided above and perpendicular to intake port 4. Therefore, even if base member 2 does not create an air flow path or does not have any parts that create a flow path, the air flow blown out from blower 1 becomes directional and the flow of the blown air can be rectified. This allows the user to feel a sufficient cooling effect, relaxes structural restrictions on the material of base member 2, and improves design freedom without reducing the cooling effect.

[0024] Furthermore, according to the embodiment based on the above drawings, the main material of the blower 1 is resin, making the main body lightweight, which reduces the burden on the user when wearing the blower cooling system.

[0025] The above-described embodiment shows a preferred embodiment of the present invention, and can be modified as appropriate within the scope of the invention. For example, although the main material of the blower 1 is resin, any material that is strong enough to withstand breakage and lightweight enough to be portable may be used, and the blower may also be made of lightweight metal.

[0026] Furthermore, in the above-described embodiment, the lower body of the blower 1 is configured to be approximately rectangular and the upper body to be approximately semicircular, but if there is an outlet 5 provided above and perpendicular to the intake port 4 of the blower 1, the shape of the body of the blower 1 is not limited to a shape in which the lower body is approximately rectangular and the upper body to be approximately semicircular, and each shape can be changed as appropriate.

[0027] Furthermore, in the above-described embodiment, the fixing member is shown to be ring-shaped, but as long as the fixing member is ring-shaped and configured to removably clamp the base member 2 between the blower 1 body and the mounting portion 6 around the suction port, the method of attaching the fixing member is not limited, and the shape can be changed as appropriate, such as by using screws or claws.

[0028] 8 to 10 show an example of a blower cooling system according to the present invention. The base member 2 is a hooded garment 12, and is composed of an attachment hole 3 provided in the hooded garment 12 and a blower 1 attached to the attachment hole 3. The blower 1 has an intake port 4 and an outlet port 5, and the outlet port 5 is provided above and perpendicular to the intake port 4.

[0029] In the above-described embodiment, the hooded garment 12 is shown configured with long sleeves, but as long as the air drawn in through the intake port 4 of the blower 1 attached to the outer surface 12a of the garment is blown out through the outlet 5 of the blower 1 attached to the inner surface 12b of the garment, and the hood portion 12c receives the air, the shape of the hooded garment is not limited to long sleeves, and the shape can be changed as appropriate, such as to short sleeves or three-quarter sleeves.

[0030] Furthermore, in the above-described embodiment, the hood portion 12c of the hooded garment 12 is configured in a deformed oval shape, but as long as it functions as the hood portion 12c that receives air from the air outlet 5 of the blower 1, the shape of the hood portion is not limited to a deformed oval shape, and can be changed as appropriate to a triangle, a rectangle, or the like.

[0031] Figure 11 shows an example of a ventilation cooling system according to the present invention. Base member 2 is a backpack 22, and is composed of mounting holes 3 provided in backpack 22 and fan 1 attached to mounting holes 3. Fan 1 has an intake port 4 and an outlet port 5, and outlet port 5 is located above and perpendicular to intake port 4.

[0032] In addition, in the above-described embodiment, the backpack 22 is configured to be worn on one side, but if the air blown from the outlet 5 of the blower 1 is directed toward the neck or back of the head of the user, the shape can be appropriately changed to a backpack worn on both shoulders or a body bag.

[0033] It should be noted that all of the above-described embodiments represent preferred embodiments of the present invention and can be modified as appropriate within the scope of the invention. For example, the blower may be rechargeable or battery-powered. A guard may be attached to the blower's intake port to prevent it from being caught in anything. The base member may be made of waterproof fabric or a plate-shaped resin. [Explanation of symbols]
