The present invention provides a cooling suit for allowing comfortable feeling even with a lesser power consumption and a simple structure. The cooling suit includes a cloth part 10a having an upper portion made of a highly air-permeable material, and having those portions other than the upper portion which are made of a substantially air-impermeable material. Formed at a reverse surface of the cloth part 10a are airflow passages between the cloth part 10a and an undergarment. Provided at a lower portion of the cloth part 10a are air outlets 50a for extracting air-streams within the airflow passages to the exterior; and provided at those positions of the reverse side of the cloth part 10a which correspond to the air outlets 50a, are fans for forcibly causing the air-streams within the airflow passages. Outside air is introduced into the airflow passages through the upper portion of the cloth part 10a by the fans, and the air-streams are flowed within the airflow passages in a manner substantially parallel to the wearer's body surface, so that the wearer's body is cooled.

The invention claimed is: 1. A cooling suit to be worn on a wearer, comprising: a cloth part; at least one air inlet provided at said cloth part and configured to introduce outside air into the interior of said cloth part; at least one air outlet provided at said cloth part and configured to extract the air within the interior of said cloth part to the exterior; at least one air-blowing means for discharging the air in a space between said cloth part and the wearer's body or an undergarment to the exterior, thereby forcibly causing air-streams within said space; at least one clearance holding means, provided to cover that surface of the at least one air-blowing means which opposes to the wearer's body or to the undergarment, and configured to hold a predetermined clearance between the at least one air-blowing means and the wearer's body or the undergarment; electric-power source means for supplying electric power to the at least one air-blowing means; and air-leakage preventing means for preventing the air-streams flowing between said cloth part and the wearer's body or the undergarment, from leaking to the exterior from a lower end of said cloth part; wherein the at least one air-blowing means introduces the outside air into the interior of said cloth part through the at least one air inlet to cause the introduced air to flow within said space and substantially parallel to a wearer's body surface, thereby increasing a temperature gradient near the wearer's body surface to thereby cool the wearer's body, and thereby contacting the air-streams flowing within said space with perspiration from the wearer's body so as to vaporize the perspiration from the wearer's body to thereby cool the wearer's body by utilizing an effect to take away evaporation heat from the surroundings upon evaporation of the perspiration. 2. A cooling suit to be worn on a wearer, comprising: a cloth part; at least one air inlet provided at a lower portion of said cloth part and configured to introduce outside air into the interior of said cloth part; at least one air outlet provided at an upper portion of said cloth part and configured to extract the air within the interior of said cloth part to the exterior; at least one sideward-flow fan configured to feed outside air into a space between said cloth part and the wearer's body or an undergarment, thereby forcibly causing air-streams within said space; electric-power source means for supplying electric power to the at least one air-blowing means; and air-leakage preventing means for preventing the air-streams flowing between said cloth part and the wearer's body or the undergarment, from leaking to the exterior from a lower end of said cloth part; wherein the at least one sideward-flow fan introduces the outside air into the interior of said cloth part through the at least one air inlet to cause the introduced air to flow within said space and substantially parallel to a wearer's body surface, thereby increasing a temperature gradient near the wearer's body surface to thereby cool the wearer's body, and thereby contacting the air-streams flowing within said space with perspiration from the wearer's body so as to vaporize the perspiration from the wearer's body to thereby cool the wearer's body by utilizing an effect to take away evaporation heat from the surroundings upon evaporation of the perspiration. 3. A cooling suit to be worn on a wearer, comprising: a cloth part; at least one air-flow opening provided at said cloth part and configured to extract air within the interior of said cloth part or to introduce outside air into the interior of said cloth part; at least one air-blowing means, provided at that position of said cloth part which corresponds to the at least one air-flow opening, and configured to forcibly cause air-streams in a space between said cloth part and the wearer's body or an undergarment; electric-power source means for supplying electric power to the at least one air-blowing means; and an air-permeating region which is a predetermined region of said cloth part positioned opposite to the at least one air-flow opening across said space and which is made of a highly air-permeable material; wherein the at least one air-blowing means introduces the outside air into said space through the at least one air-flow opening or through said air-permeating region to cause the introduced air to flow within said space and substantially parallel to a wearer's body surface, thereby increasing a temperature gradient near the wearer's body surface to thereby cool the wearer's body, and thereby contacting the air-streams flowing within said space with perspiration from the wearer's body so as to vaporize the perspiration from the wearer's body to thereby cool the wearer's body by utilizing an effect to take away evaporation heat from the surroundings upon evaporation of the perspiration. 4. The cooling suit of any one of claims 1, 2, and 3, further comprising air guiding means provided within said space and for flowing the air-streams along predetermined paths within said space. 5. The cooling suit of any one of claims 1, 2, and 3, wherein said electric-power source means comprises a fuel cell. 6. The cooling suit of any one of claims 1, 2, and 3, wherein said electric-power source means supplies electric power to the at least one air-blowing means via cord. 7. The cooling suit of any one of claims 1, 2, and 3, further comprising a controlling circuit and a receiving circuit, wherein said electric-power source means, said controlling circuit and said receiving circuit are associated with the at least one air-blowing means, and wherein the driving operation of the at least one air-blowing means is controlled by wirelessly transmitting a signal to said receiving circuit from exterior transmitting means. 8. The cooling suit of any one of claims 1, 2, and 3, further comprising a controlling circuit and a receiving circuit both associated with the at least one air-blowing means, wherein the driving operation of the at least one air-blowing means is controlled by wirelessly transmitting a signal to said receiving circuit from exterior transmitting means. 9. The cooling suit of any one of claims 1, 2 and 3, wherein the at least one air-blowing means is mounted on a reverse side of said cloth part in a manner that the rotational axis of the at least one air-blowing means is substantially perpendicular to a surface of the wearer's body or of the undergarment. 10. The cooling suit of any one of claims 1, 2 and 3, wherein the at least one air-blowing means is mounted at a predetermined position of a reverse side of said cloth part, so that, that end surface of the at least one air-blowing means which opposes said cloth part, is substantially flush with an obverse surface of said cloth part. 11. The cooling suit of any one of claims 1, 2 and 3, wherein the at least one air-blowing means is provided at that position of said cloth part, which is slightly shifted from the flank portion to the back portion of said cloth part. 12.
