Description

Cooling control helmet using thermoelectric semiconductors {The cooling helmet for working}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a helmet for control (control hair), and more particularly, to a helmet for cooling using the heat transfer effect of a thermoconductor.

In the conventional control helmet, as shown in the control helmet disclosed in Patent Registration No. 198029, the solid ice pack is inserted into the upper part of the helmet and then forcedly inhaled by using a fan motor installed at the rear of the helmet. It was a helmet for controlling the type of the air to lower the temperature of the air by passing through the space portion of the solid ice pack to supply to the face of the worker.

Therefore, when a worker working in hot weather or high temperature inserts a solid ice pack into the control helmet, and the work is no longer cool because the solid inside the ice pack changes to liquid, the solid ice pack must be replaced again. In addition, there is a problem that the replacement cycle is short and the work efficiency is lowered, and there is a difficulty of always storing an adequate number of solid ice packs for replacement.

In addition, publication number 96-10506 (thermostat of a helmet using a thermoelectric element) disclosed in Patent Publication No. 4583 is mainly used for the safety of drivers of a test vehicle, a motorcycle, a sports car, and somewhat different from a helmet for control. Although there is a difference, it is similar in terms of its function, and when it is mentioned, the problem of replacing the above-mentioned solid ice packs is solved. However, since it is a natural ventilation type, the heat generated from the thermoelectric element in hot weather, especially in the absence of wind speed, is There is a possibility that the heat transfer effect is not seen due to the emission of heat, and the thermoelectric element may be damaged due to the effect of overload. In addition, it is not designed to supply fresh air all the time, so it is not possible to spray pesticides or fertilizers or to supply workers with fresh air to their face constantly on hot summer days. The dust is adhered to the face and eyes, there is also a problem of safety accidents.

The present invention has been made to solve the problems of a known helmet consisting of a thermoelectric element, a heat dissipation fin, a thermoelectric element control means and a known helmet for ice pack, fan motor, filter, control means, among the above components In addition to thermoelectric elements, heat sink fins, air intake fan motors, filters, and control means for thermoelectric elements, additional cooling plates, heat sinks, cold preservation gel packs, and fan motors for radiating air exhaust are provided, and the structure is changed to supply new air smoothly. It aims to enable workers to effectively spray pesticides or fertilizers in a safe working environment.

In addition to the above configuration, the control helmet A includes an air intake 16, a space 17, and a blower 18.

Referring to the structure of the present invention configured as described above are as follows.

In the outer center of the outer body (1) of the control helmet (A) is formed a certain size of the projecting portion for installing the thermoelectric semiconductor (8), the heat sink (9) and the fan motor for discharging the heat radiation, The protrusion formed by the heat dissipation air outlet 12 for dissipating heat generated by the thermoelectric semiconductor 8 is provided.

On the rear side of the control helmet (A), a filter (5) for purifying air and a fan motor (6) for sucking air are mounted between the outer body (1) and the inner body (2). In front of the inner surface of the body (2) is equipped with a cold air preservation gel pack (4) for storing the cold air generated in the thermoelectric semiconductor (8), between the outer body (1) and the inner body (2) thermoelectric semiconductor (8). Cooling plate (7) which is able to absorb the low temperature generated by the () quickly is mounted. In the center portion of the cooling plate 7, a thermoelectric semiconductor 8 is mounted, and a heat sink 9 for dissipating heat generated by the thermoelectric semiconductor 8 is mounted thereon, and a heat sink 9 is disposed on the heat sink 9. It is equipped with a fan motor 11 for discharging the heat radiation air so as to quickly release the heat absorbed from the). In addition, the control helmet (A) is equipped with a viewing window (3) to prevent dust scattered from them when spraying pesticides or fertilizers to reach the face or eyes of the worker, the viewing window (3) is for convenience of the operator It was possible to move down.

In the above structure, between the cooling plate 7 and the inner body 2, there is a space 17 through which the air sucked from the air inlet 16 can pass, and is located in the middle of the space 17. There is a blower 18 for discharging air cooled by the thermoelectric semiconductor 8 and the cooling plate 7 to the face of the operator, and between the cooling plate 7 and the outer body 2 of the cooling plate 7 A constant space is maintained to minimize the transfer of cold air to the outside.

And in the control helmet (A) configured as described above, the charging means that is a control means (C) for supplying power to the thermoelectric semiconductor (8), the air suction fan motor (6) and the heat discharge air fan motor (11). A speed controller 15 for adjusting the speed of the battery 13, the power switch 14, and the air suction fan motor 6 is mounted on the waist of the operator.

Referring to the operation of the present invention configured as described above is as follows.

First, when the power is turned on while the helmet H is worn on the operator's head, current flows to the thermoelectric semiconductor 8 so that the upper portion of the thermoelectric semiconductor 8 is changed according to the characteristics of the thermoelectric semiconductor 8. It becomes high temperature and the lower part becomes low temperature.

According to the characteristics of the thermoelectric semiconductors 8 as described above, the cooling plate 7 installed at the lower portion of the thermoelectric semiconductors 8 is cooled to a low temperature by the heat transfer effect of the thermoelectric semiconductors 8 and cooled to a low temperature. When the outside hot air sucked from the air intake port 16 passes through), the hot air cools down because heat is removed by the cold air of the cooling plate 7. At this time, the heat generated from the upper portion of the thermoelectric semiconductor (8) and the heat absorbed from the cooling plate (7) installed in the thermoelectric semiconductor (8) is absorbed by the heat sink (9) and the heat dissipation fin (10) provided on the upper portion of the thermoelectric semiconductor (8). The heat absorbed by the heat dissipation plate 9 and the heat dissipation fin 10 is discharged to the heat dissipation air outlet 12 by the fan motor 11 for dissipating air. As this process is repeatedly performed, the external hot air passing through the cooling plate 7 is changed to the fresh air, and provides the fresh air to the face of the worker through the tuyeres 18. In addition, the fresh air is preserved in the cold preservation gel pack 4 through the above-described process to be repeated repeatedly to cool the head and face of the worker.

And by adjusting the speed of the air intake fan motor 6 by operating the speed controller 15, the control means (C), it is possible to adjust the amount of air sucked so that the operator can work in the optimum working conditions.

The effect of the present invention described above is to protect the worker from the spraying of pesticides or fertilizers, high temperature, dust and poisonous gas, and to provide the operator with fresh air to the face continuously so that the worker can work in a comfortable state. At the same time it is possible to solve the problem of the control helmet helmet using the conventional ice pack, that is, the replacement and replacement cycle of the ice pack is short, reducing the work effect of the worker.
