Description

Technical Field

[0001] This invention relates to a cooling garment, and more specifically, to a cooling garment that, for workers in various special environments such as construction sites, industrial facilities, and agriculture, can be easily worn to prevent health problems such as heatstroke, dehydration, and fatigue caused by rising body temperature in summer, and to prevent discomfort and skin diseases caused by sweat-soaked work clothes. Moreover, it can maintain a comfortable environment in daily life, sports, or outdoor activities, even in hot weather, thereby preventing decreased concentration and fatigue accumulation caused by prolonged body temperature rise, thus ensuring the user's safety and physical activity efficiency. Background Technology

[0002] Cooling clothing is a type of functional garment developed to lower body temperature and maintain comfort in hot environments. Initially, it mainly used highly breathable fabrics to promote sweat evaporation and heat dissipation. Subsequently, technologies were introduced to insert gel-type cooling pads or absorbent materials into the garment to lower body temperature.

[0003] At the same time, it is developing in multiple directions, including the development of a method that uses phase change materials (PCM) to absorb heat when body temperature rises, and the emergence of smart cooling clothing technology that uses temperature detection sensors and conductive fibers to provide users with customized cooling effects, as well as the application of emissivity adjustable fiber technology that reflects or releases heat of specific wavelengths.

[0004] This type of cooling clothing can effectively reduce the risk of fatigue and heatstroke caused by elevated body temperature, and improve heat management for people active in hot environments, thus finding positive applications in real-world scenarios.

[0005] On the other hand, the cooling clothing currently in use can be roughly divided into two types according to its operating method: cooling fluid circulation type and air supply type. The cooling fluid circulation type has a structure in which a refrigerant pipe is set in the clothing, so that the cooling refrigerant circulates in the refrigerant pipe, thereby providing cold air to the human body.

[0006] Therefore, although the cooling fluid circulation system has the advantages of effectively reducing body temperature and providing a constant cooling effect for a long time, the diffusion effect of the cold air is insufficient because the cold air acts locally around the refrigerant pipe. As a result, it has the disadvantage of providing limited cooling in the area where the refrigerant pipe is located, and there is also the problem of condensation around the refrigerant pipe, which causes clothing to get wet.

[0007] In addition, the air-supply type is limited to forcibly injecting the air around the clothing into the clothing and circulating it. Therefore, when used in high-temperature working environments, it is not effective in reducing body temperature, and it also has the structural problem that its cooling effect is significantly lower than that of the cooling fluid circulation type.

[0032] Hereinafter, specific embodiments of the cooling garment of the present invention will be described with reference to the accompanying drawings.

[0033] During the summer, outdoor workers often experience heatstroke, dehydration, fatigue, and other health problems due to prolonged work in high-temperature environments. Their sweat-soaked work clothes cause discomfort and skin diseases, and direct exposure to sunlight increases the risk of heatstroke and burns. High temperatures also lead to decreased concentration and accumulated fatigue, resulting in reduced work efficiency and other distressing issues.

[0034] Therefore, for workers in special environments such as construction sites, industrial facilities, and agriculture, simply wearing this device can help regulate body temperature, thereby improving safety and work efficiency, and ultimately ensuring production efficiency.

[0035] Moreover, wearing cooling clothing in daily life, sports, or outdoor activities can maintain a comfortable environment even in hot weather, thereby improving the quality of life. Furthermore, with the increasing prevalence of hot and humid climates globally, the necessity of cooling clothing as an important solution to address climate change is constantly growing.

[0036] As described in the background section, cooling clothing can regulate body temperature by simply applying highly breathable cooling materials or by using cooling fluid circulation and air supply structures, but each method still has its drawbacks.

[0037] This invention maximizes cooling performance by overcoming the shortcomings of both circulating and air-supplying cooling systems and highlighting their respective advantages, thereby ensuring user satisfaction and maximizing body temperature regulation. Based on this fundamental development concept of cooling clothing, specific embodiments of the cooling clothing of this invention will be described below with reference to the accompanying drawings.

[0038] The cooling garment of the present invention may be exemplified by generally including a wearing part 10, a pipe part 100, a cooling part 20 and a blower motor 30.

[0039] First, the wearing part 10 is the structure responsible for the overall appearance of the cooling garment of the present invention, and has a conventional garment shape so that it can be worn by the user.

[0040] As an example, the clothing part 10 can be appropriately modified according to the usage environment or purpose, for example, it can have the shape of a vest or other top that is only worn on the upper body of the user, or it can be implemented in the form of a suit that can cover the upper and lower body extensively.

[0041] The wearing part 10 is composed of a double-layer structure, namely an inner skin 11 that contacts the user's body and an outer skin 12 attached to the outside of the inner skin 11, and has a structure in which a channel part 100 is suitably built into the inner skin 11 and the outer skin 12.

[0042] At this time, part or all of the inner skin 11 and the outer skin 12 can be achieved by appropriate material combination according to the usage environment of the cooling garment. For example, part or all of the inner skin 11 and the outer skin 12 can be made of lightweight breathable materials, such as polyester, nylon, cotton blends, etc. The materials can promote sweat evaporation, facilitate air circulation, and quickly release heat and moisture to keep the skin dry.

[0043] As another example, part or all of the inner skin 11 and the outer skin 12 may be made of special cooling fibers known to provide a cooling effect on the fabric itself.

[0044] As another example, part or all of the endothelial 11 and the outer skin 12 may be made of a known emissivity-tunable material that can prevent the accumulation of heat in the body by reflecting or releasing heat of a specific wavelength.

[0045] In particular, at least one of the inner skin 11 and the outer skin 12 may be made of a mesh structure with excellent breathability, such as a functional mesh fabric woven in a perforated mesh form. In a preferred embodiment, both the inner skin 11, which is in direct contact with the user's body, and the outer skin 12 attached to such inner skin 11 are made of mesh fabric, or the inner skin 11 may be mesh and the outer skin 12 may be made of fabric with windproof, waterproof, water-repellent and other functions.

[0046] When the outer skin 12 is made of a fabric with windproof, waterproof and water-repellent functions, it can effectively prevent the loss of cold air released in the space between the inner skin 11 and the outer skin 12.

[0047] Next, the duct section 100 is a duct structure that provides ductwork for the movement of refrigerant and compressed air supplied from the refrigeration section 20 and the blower motor 30, and performs the function of cold air transmission and diffusion by extending to the entire part of the wearing section 10.

[0048] In particular, the most significant feature of the pipe section 100 in this embodiment is that it does not employ a single-pipe structure that separately transports refrigerant and compressed air supplied from the refrigeration section 20 and the blower motor 30, but rather a double-pipe structure that can provide sufficient cooling air by mixing refrigerant and compressed air.

[0049] That is, the cold air from the refrigerant supplied by the refrigeration unit 20 and the compressed air supplied by the blower motor 30 exchange heat with each other and provide compressed air at a lower temperature, thereby creating a more comfortable environment.

[0050] Therefore, as an embodiment, the piping section 100 may be exemplified as generally including an air pipe 110, a refrigerant pipe 120, a branch pipe 130, and a drain pipe 140.

[0051] First, the air pipe 110 is a pipe structure that is connected to the blower motor 30 and forms an air circulation path inside the wearing part 10.

[0052] The two ends of the air pipe 110 are connected to each other to form a closed path structure, and on the path of the air pipe 110 in this closed path structure, a single injection pipe 111 branches out and has a structure that is directly connected to the blower motor 30.

[0053] Therefore, when the blower motor 30 operates and supplies compressed air to the injection pipe 111, the compressed air passing through the injection pipe 111 is distributed to both sides of the air pipe 110 to achieve supply. On the other hand, the air pipe 110 has a structure in which a plurality of air discharge holes 112 are formed through the length direction of the air pipe 110 so as to discharge compressed air to the outside.

[0054] At this time, when the air discharge hole 112 is biased towards the inner skin 11 or outer skin 12 covering the outside of the air pipe 110, there is a problem that the compressed air discharged from the air discharge hole 112 is directly blocked by the inner skin 11 or outer skin 12 (or even the body), thus reducing the discharge pressure.

[0055] Therefore, in this embodiment, as Figure 6 As shown, each air discharge hole 112 has the following structure: it is formed through a direction perpendicular to the direction facing the body, and is not blocked by the inner skin 11, the outer skin 12 or the body, so as to smoothly discharge the compressed air introduced into the air pipe 110 into the space between the inner skin 11 and the outer skin 12.

[0056] This air pipe 110 forms the outermost part of the pipe section 100. Since the refrigerant pipe 120 is located inside the pipe section 100, the air pipe 110 and the refrigerant pipe 120 have a double pipe structure.

[0057] Next, branch pipes 130 are arranged in pairs along the path of air pipe 110 to guide the refrigerant pipe 120 (described later) into the inside of air pipe 110.

[0058] For example, the air pipe 110 can be segmented, and branch pipes 130 can be provided at both ends of the segmented air pipe 110, and the branch ends 131 can be branched. The branch ends 131 are used to introduce and guide the refrigerant pipe 120 into the air pipe 110.

[0059] In other words, one end of the branch pipe 130 is connected to the air pipe 110, and the branch end 131 formed by the additional branch can branch from the air pipe 110 in another direction and introduce and guide the refrigerant pipe 120 into the air pipe 110.

[0060] Next, the refrigerant pipe 120 is a pipe structure in which both ends are connected to the refrigeration section 20 and a refrigerant circulation path is formed inside the wearing section 10.

[0061] At this time, the cooling section 20 is provided on the outside of the wearing section 10. For the cooling section 20 with this external structure, the two ends of the refrigerant pipe 120 are respectively connected to the cooling section 20 and introduced into the branch end 131 of the branch pipe 130, so that it has a structure that extends along the length direction of the air pipe 110 inside the air pipe 110.

[0062] In the refrigerant pipe 120, the low-temperature, low-pressure refrigerant, which exchanges heat under the action of the refrigeration section 20, circulates. Under the action of this refrigerant, strong cold air is released around the refrigerant pipe 120. At this time, the refrigerant pipe 120 itself is a structure installed inside the air pipe 110. After the compressed air injected into the air pipe 110 exchanges heat with the cold air around the refrigerant pipe 120, it is discharged under high pressure through the air discharge hole 112, thereby providing a cooling sensation to the user.

[0063] That is, since the cooling effect is not limited to the refrigerant itself in the circulating refrigerant pipe 120, but is realized by a structure that can discharge the cold air provided by the refrigerant at high pressure, the heat exchange between the refrigerant and the air supply is carried out more effectively and the cooling effect transferred to the body is further maximized. Furthermore, since the refrigerant pipe 120 and the air pipe 110 can be structurally integrated, the space utilization between the limited inner skin 11 and outer skin 12 can be improved. Moreover, there is no need to set up the refrigerant pipe 120 and the air pipe 110 separately, the structure is simpler, and the foreign body sensation on the user's skin is minimized, thereby improving the wearing comfort.

[0064] In addition, since the refrigerant pipe 120 is located inside the air pipe 110, not only can heat loss caused by the external environment be minimized, but the compressed air can also regulate the temperature of the surface of the refrigerant pipe 120, thereby suppressing condensation.

[0065] On the other hand, most refrigeration clothing is used in high-temperature environments. In this case, the temperature of the refrigerant itself in the refrigerant pipe 120 is usually significantly lower than the dew point temperature of the moisture contained in the surrounding air. Therefore, it is obvious that even if compressed air is provided, condensation will form on its surface.

[0066] If the condensate flowing out in this way is not properly handled, it will soak the wearing part 10 and cause discomfort. If the wearing part 10 is soaked with condensate for a long time, it will not only increase the risk of skin diseases or infections, but also damage the wearing part 10 or reduce the cooling performance due to condensation around the refrigerant pipe 120. When the condensate flows into the cooling part 20 or the blower motor 30, there is a possibility of damage to electronic components or safety problems.

[0067] However, in this embodiment, the refrigerant pipe 120 itself is a structure installed inside the air pipe 110, and is not a structure directly exposed to the outside. Moreover, the air pipe 110 that encloses the refrigerant pipe 120 forms a closed path. Therefore, the condensate generated on the outer surface of the refrigerant pipe 120 is naturally confined inside the air pipe 110, so the amount that flows out toward the wearing part 10, the cooling part 20, the blower motor 30, etc. is extremely small.

[0068] In addition, since the moisture inside the air pipe 110 is released to the outside by the pressure of compressed air, a structure that maintains a dry state can be achieved.

[0069] Furthermore, by using the drain pipe 140 described later to guide the condensate collected inside the air pipe 110 to be discharged in a certain direction, various problems caused by the disorderly generation of condensate are solved.

[0070] More specifically, a sealing cap 150 for sealing the open branch end 131 is provided at the branch end 131 of the branch pipe 130, and the drain pipe 140 can be formed by extending a certain length outward from the sealing cap 150, thereby guiding the condensate to be discharged in a certain direction.

[0071] At this time, the branch pipe 130 is located approximately at the user's waist when the user is wearing the cooling suit. The drain pipe 140 extends further downward from this branch pipe 130, so that the condensate does not flow directly to the wearing part 10, the cooling part 20, the blower motor 30, etc., but can be continuously discharged towards the ground.

[0072] Next, the refrigeration section 20 is connected to the refrigerant pipe 120 of the piping section 100, and serves to circulate the refrigerant through the refrigerant pipe 120 of the piping section 100.

[0073] At this time, the refrigeration unit 20 has a conventional heat exchanger structure for applying a refrigeration cycle. For example, it may include, in addition to a variable-diameter coil 21 and a motor 22, valves, a condenser, a compressor, a power supply unit, a control unit, etc. The variable-diameter coil 21 serves as a physical channel for the refrigerant to circulate and repeat state changes (liquid → gas, gas → liquid), supporting the continuous operation of the refrigeration cycle by compressing and expanding the refrigerant; while the motor 22 provides pressure for the refrigerant cycle. Besides the structure described above, it may include structures required for the refrigeration cycle, or it may be modified in various ways from known sources. Therefore, a detailed description of the refrigeration unit 20 will be omitted.

[0074] The blower motor 30 can be encapsulated together with the cooling unit 20 inside a separate housing 40, which is configured to be connected to the outside of the wearing part 10 so as not to hinder the movement of the body.

[0075] Meanwhile, although not shown, an actuation switch is connected to the housing 40 to control the operation of the cooling unit 20 and the blower motor 30.

[0076] At this point, the switch basically supports a cooling mode in which the cooling unit 20 and the blower motor 30 operate simultaneously, and can also support a blower mode in which the operation of the cooling unit 20 is terminated and only the blower motor 30 operates, as needed.

[0077] This air supply mode can be expected to save energy by using only the blower motor 30, or provide a drying function inside the air duct 110.

[0078] The interior of the air pipe 110 is a sealed structure, making it difficult for cleaning tools to enter. Due to its multiple bends, there is a higher possibility of condensation residue, which increases the likelihood of mold growth and makes hygiene management difficult. However, after the cooling garment has been used, when compressed air is continuously supplied to the interior of the air pipe 110, a strong ventilation effect is applied to the interior of the air pipe 110. This can more effectively dry the residual condensation inside the air pipe 110 or on the surface of the refrigerant pipe 120, making it easier to clean and manage the internal structure of the air pipe 110.

[0079] In summary, the advantages provided by this invention are as follows: For workers in various construction sites, industrial facilities, agriculture and other special environments, simply wearing this garment can prevent health problems such as heatstroke, dehydration and fatigue caused by rising body temperature in summer, and prevent discomfort and skin diseases caused by sweat-soaked work clothes. Moreover, it can maintain a comfortable environment in daily life, sports or outdoor activities, even in hot weather, thereby preventing decreased concentration and fatigue accumulation caused by prolonged body temperature rise, thus ensuring the user's safety and physical activity efficiency.

[0080] The embodiments of the present invention described above are merely exemplary, and those skilled in the art will recognize that various modifications and equivalent embodiments are possible. Therefore, it should be understood that the present invention is not limited to the forms mentioned in the detailed description above. Thus, the true scope of protection of the present invention should be determined by the technical concept of the appended claims. Furthermore, it should be understood that the present invention includes all modifications, equivalents, and substitutions within the spirit and scope of the invention as defined by the appended claims.
