Benefits of technology

[0004] The present invention has been carried out in view of such a technical background, and it is therefore an object of the present invention to provide cooling bedclothes, cooling seat cushion, cooling mat, cooling chair, cooling clothing and cooling shoes, which provide a sufficient cooling effect with a simple structure and without health damage.

Problems solved by technology

However, obtaining cooled air requires a separate device therefor, thereby increasing cost.
Further, the method to directly blow the cooled air onto the body has a higher cooling effect, but may increase the risk of damage to health.

embodiment 1

[0059] Embodiment 1

[0060] FIG. 7 is a view showing an underlying futon according to a first embodiment of the present invention applied to cooling bedclothes. FIG. 7(a) is a plan view and FIG. 7(b) is a left side view of the cooling bedclothes. The cooling bedclothes of this embodiment have a structure comprising cooling flow passages or collective cooling flow passage 31 placed on a cushion 30. As shown in FIG. 7(a), a connecting passage 32 is provided at the right side of a supine person, and a fan 33 of 60 square is provided at the end of the flow connecting passage 32 adjacent to the feet of the person. The cooling flow passage 31 has a lateral side constituting an air inlet at which the flow connecting passage 32 is provided (i.e., the right side of the lying person), and the other lateral side constituting an air outlet 34. As shown in FIG. 7(b), the air outlet 34 is provided to face downwardly at the side of the cushion. This is to avoid a situation where the air outlet is cl...

embodiment 2

[0064] Embodiment 2

[0065] FIG. 8 is a view showing a chair seat cushion according to a second embodiment of the present invention applied to a cooling seat cushion. FIG. 8(a) is a plan view and FIG. 8(b) is a center cross-sectional view of the cooling seat cushion. FIG. 9 is a view showing the chair seat cushion according to the second embodiment of the present invention applied to the cooling seat cushion.

[0066] Cooling seat cushion 40 of this embodiment is used in a manner placed on a chair 41 as shown in FIG. 9. The cooling seat cushion can be of course placed such as on a bench or sofa. The cooling seat cushion 40 of this embodiment basically constituted of two portions, i.e., a main portion 42 and a seat 43. The main portion 42 comprises a square spacer portion 44 of 400 mm length and 400 mm width, and a controlling part 46 provided at the rear side of the spacer portion 44. The spacer portion 44 has a top side provided with many projected subspacers. The main portion 42 compri...

embodiment 3

[0072] Embodiment 3

[0073] FIG. 10 is a view showing a mat such as usable on a sofa or floor according to a third embodiment of the present invention applied to a cooling mat. FIG. 10(a) is a plan view and FIG. 10(b) is a cross-sectional view of the cooling mat, and FIG. 11 is a view showing which portion of a body is cooled by the mat.

[0074] Cooling mat 60 of this embodiment is used in a manner to mainly cool the upper half of the body when a person rests such as on a floor or sofa as shown in FIG. 11. The basic structure of the cooling mat 60 of this embodiment basically comprises two portions, i.e., a main portion 62 and a seat 63, similarly to the cooling seat cushion according to the Embodiment 2. The main portion 62 comprises a rectangular spacer portion 64 of 900 mm length and 450 mm width, many subspacers provided on the top side of the spacer portion 64, and a controlling part 66 provided at the rear side of the spacer portion 64. These portions are integrally manufactured b...

Abstract

Each of the cooling bedclothes, cooling seat cushion, cooling mat, cooling chair, cooling clothing and cooling shoes, to which the present invention is applied, has such a commonized structural feature to form the cooling flow passages in a substantially parallel and planar manner in the portion of such an article adjacent to the body, and utilizes such a commonized cooling effect to cause the ambient air at a temperature lower than the body temperature to flow through the cooling flow passages substantially parallelly to the body surface to thereby cool the body. Namely, the present invention forms, at a location extremely adjacent to the body surface of a person, an air layer having a temperature equal to that in the room without lowering the temperature of the whole room, thereby forcibly increasing the temperature gradient near the body surface to thereby increase the extent of heat release from the body, resulting in feeling of coolness. To form the air layer having the temperature equal to that in the room adjacently to the body surface, it is advisable to form a flow passage of air adjacently to the body surface, and to cause the air in the room to flow through the flow passage parallelly to the body surface. To form the flow passage, each of the embodiments of the present invention adopts a spacer having a suitable configuration.

Description

TECHNICAL FIELD[0001] The present invention relates to cooling bedclothes, cooling seat cushion, cooling mat, cooling chair, cooling clothing and cooling shoes, for causing ambient air to flow parallelly to the vicinity of the body surface to thereby cool the same.BACKGROUND ART[0002] As bedclothes for cooling a body such as at a sleepless summer night, devices for directly cooling the body have been proposed such as by causing cooled air to flow into a futon and / or pillow. It has been also proposed to directly blow the thus cooled air onto the body such as from small holes provided on a futon and / or pillow.[0003] However, obtaining cooled air requires a separate device therefor, thereby increasing cost. Further, the method to directly blow the cooled air onto the body has a higher cooling effect, but may increase the risk of damage to health.DISCLOSURE OF INVENTION[0004] The present invention has been carried out in view of such a technical background, and it is therefore an object...
