Claims (3)

1. It is configured to include an upper body that wraps around the upper body of a wearer; and a thermoelectric element-based cooling unit provided on the upper body to cool the body surface of the wearer. The above upper body includes an outer skin formed of a windproof fabric and an inner skin having a mesh structure provided on the inner side of the outer skin. A storage pocket for storing and fixing the cooling unit is formed in the upper body, and the cooling unit is configured to include a battery that supplies a starting current, a thermoelectric element unit equipped with a hot element that emits heat on one side and a cold element that emits cold air on the other side when current is applied, an air supply circulation fan unit that forcibly draws in and supplies external air, and an air supply distribution duct that distributes the external air introduced through the air supply circulation fan unit to the hot element and the cold element, respectively. A thermoelectric element-based cooling workwear characterized in that the hot and cold units are each provided with a circulation discharge pipe having a supply air port communicating with the supply air distribution duct, and external air flows along the circulation discharge pipe of the hot unit to cool the hot unit and is discharged to the outside, and flows along the circulation discharge pipe of the cold unit to cool and is then ejected into the interior of the upper body.

3. In claim 1, a section for incorporating a constricted pipe with a reduced diameter is formed in the circulation discharge pipe of the hot piece, while, A thermoelectric element-based cooling workwear characterized by being configured such that a water supply pipe communicating with a reservoir containing cooling water is connected to the above-mentioned pipe mixing section, and the cooling water from the reservoir naturally flows in due to the reduced pressure state formed as external air passes through the above-mentioned pipe mixing section, thereby allowing the above-mentioned hot piece to be combined-cooled by the external air and the cooling water mixed in.

Description

Thermoelectric-Based Active Cooling Work Garment The present invention relates to a thermoelectric element-based cooling workwear, and more specifically, to a thermoelectric element-based cooling workwear for actively cooling the wearer's body in environments exposed to high temperatures or direct sunlight, such as indoor work in greenhouses, construction sites, road paving work, and industrial facility maintenance work. Generally, cooling clothing is used to suppress the rise in body temperature of workers when performing long-term work in high-temperature environments, such as inside greenhouses, construction sites, road paving work, steel structure construction sites, and industrial equipment maintenance sites. In particular, the interior of a vinyl greenhouse has a characteristic where the temperature rises significantly higher than the outside due to its sealed structure, and in the summer, the internal temperature frequently rises above 40℃. In addition, there is a problem where the perceived temperature rises rapidly at construction sites or outdoor work sites due to the influence of direct sunlight and radiant heat, significantly increasing worker fatigue and heat stress. Accordingly, various types of cooling clothing have been proposed to reduce the body temperature of workers. Conventional cooling garments are primarily constructed by inserting ice packs into pockets inside the garment to deliver cold air for a certain period of time, or by using small fans to draw external air into the garment to induce air circulation. However, the method using ice packs has the problem that the preparation process is cumbersome because it requires freezing in advance, and it is difficult to maintain a sufficient cooling effect during long-term work due to the limited duration of the cooling. In addition, there is a disadvantage in that the weight of the ice pack reduces wearing comfort and restricts activity. On the other hand, fan-based air circulation methods result in limited cooling effects when ambient temperatures are high, as they merely circulate hot air; furthermore, the cleanliness of the intake air can be an issue at construction sites with significant dust or foreign matter. In addition, there is the problem of difficulty in using the device continuously for extended periods due to limitations in battery life. Therefore, there is an increasing demand for a new type of cooling garment that can stably suppress body temperature rise for extended periods in high-temperature working environments, while also featuring a lightweight structure and a simple preparation process.
