Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cooling suit used by crew members such as aircraft.

[0002]

[Prior Art and Problems] Conventional cooling suits worn by aircraft occupants have water resistance and high airtightness, so the inside of the cooling suit becomes hot and humid, which deteriorates the environment and hinders work. There is a fear.

In order to eliminate such drawbacks, a conventional cooling suit sends a compressed air from a hose connected to a pump to the cooling suit to ventilate the air in the cooling suit, thereby improving the atmosphere in the cooling suit. Is being done.

However, in such a method of feeding compressed air into the cooling suit, only the vicinity of the cooling suit portion into which the compressed air is fed is cooled, and the limbs such as limbs are sufficiently distant. It had the drawback that it was not ventilated by compressed air. That is, in the conventional cooling suit, there is a drawback that the resistance is large and the end is not affected because air is only sent into the cooling suit by the pump (there is no discharge port).

[0005]

In order to solve the above problems, the cooling suit according to the present invention is provided with an exhaust hose communicating with the inside of the cooling suit main body, and an air inside the cooling suit main body connected to the exhaust hose. A suction pump for sucking air into the cooling suit body, at least one air suction port penetrating the inside and outside of the cooling suit body, and the air suction port. Is characterized by having a valve that closes.

In the cooling suit according to the present invention, as described above, the air in the cooling suit is sucked and exhausted by the suction pump, and the outside air is sucked in by the air suction port. By providing it, it becomes possible to take in outside air into the cooling suit evenly. Further, the air suction port is opened by the suction force (negative pressure) of the pump,
Since a valve that closes when a pressure higher than the suction force of the pump such as water pressure is applied is provided, in the normal case, the air in the cooling suit can be satisfactorily ventilated by the action of the suction pump, and In the case of untimely landing, there is an advantage that water does not flow into the cooling suit due to the water pressure.
