Description

Technical Field

[0001] The utility model relates to the technical field of refrigeration equipment, in particular to an air-conditioning garment. Background Art

[0002] The invention of air conditioners has greatly improved people's lives, but air conditioners are only suitable for use in relatively closed spaces and cannot be used outdoors or in some special occasions, such as die-casting workshops, heat treatment workshops, etc. This makes the working environment of people working in the above occasions harsh. High temperature and high cold environment will seriously endanger human health and easily cause work errors.

[0003] In order to improve the comfort of workers in the above special environment, a clothing cooling device is disclosed in the patent document with the publication number WO2024101094A1, which includes a Peltier element in a housing, cooling fins formed on one side of the Peltier element, heat dissipation fins formed on the other side, and a blower that sends air to the cooling fins and the heat dissipation fins. Attached to the clothes to cool the inside of the clothes. The clothing cooling device has an air inlet opened in the housing for the blower to draw in external air, a cold air outlet from which the cold air passing through the cooling fins is discharged, and a heat dissipation outlet from which the cold air passing through the cooling fins is discharged. The hot air passing through the heat dissipation fins is discharged, and the opening is in the opposite direction of the housing. The cold air outlet has a flange, and the flange is detachably connected to the inner and outer peripheral surfaces of the opening formed in the clothes.

[0004] In the above solution, since the clothing cooling device is installed in the pocket of the clothing and the cold air outlet of the clothing cooling device is arranged inside the clothing, the cold air generated by the heat sink can be directly and efficiently used on the body parts that need to be cooled.

[0005] However, the cooling method of this solution causes the cold air to dissipate quickly, resulting in low energy utilization efficiency and poor cooling effect. Summary of the Invention

[0006] The utility model aims to solve the technical problem that the clothing cooling device in the prior art cannot gather cold air, and the cold air quickly dissipates into the surrounding environment after flowing through the body, resulting in poor cooling effect and low energy utilization efficiency.

[0007] In order to solve the above technical problems, the utility model provides an air-conditioning garment, comprising a garment and a cooling fan assembly detachably arranged on the back of the garment, wherein the garment comprises a back inner layer in contact with the back of the human body; the cooling fan assembly comprises a pad and a semiconductor cooling fan detachably arranged on the pad; a flange is provided on the side of the pad close to the back inner layer for supporting the back inner layer to form a cavity; the semiconductor cooling fan has a cold air inlet, a cold air outlet and a fan, and the cold air inlet and the cold air outlet are both in communication with the cavity. The cold air blown out from the cold air outlet exchanges heat with the human body in the cavity, and is then sucked into the semiconductor cooling fan from the cold air inlet by the fan for cooling, and then discharged from the cold air outlet, and the cold air circulates in the cavity and the semiconductor cooling fan.

[0008] In the above structure, a flange is provided on the liner, and the flange and the inner layer of the back of the clothes are combined to form a cavity. The cold air inlet and cold air outlet of the semiconductor cooling fan are both connected to the cavity. This arrangement can not only gather cold air in the cavity and cool down the back of the human body through the inner layer of the back; moreover, the air with a higher temperature after heat exchange with the human body is again sucked into the semiconductor cooling fan from the cold air inlet by the fan for cooling. Since the air temperature in the cavity is lower than the air temperature outside the clothes at this time, the temperature will be lower after cooling by the semiconductor cooling fan, and the cooling effect will be better. Since the cold air of this structure is not easily dissipated into the surrounding environment, it will not cause waste, so the utilization rate of electric energy will be higher.

[0018] The present invention will be described in further detail below with reference to the accompanying drawings and specific implementation methods.

[0019] like Figures 1 to 3 As shown, an air-conditioning garment comprises a garment 1 and a cooling fan assembly 2 detachably arranged on the back of the garment 1 .

[0020] like Figure 2 and Figure 3 As shown, the garment 1 includes a back inner layer 10 that contacts the back of the human body and a back outer layer 12. The back outer layer 12 is sewn together with the back inner layer 10 to form a space for accommodating the cooling fan assembly 2. In this embodiment, the back inner layer 10 is a skin-friendly and breathable fabric; the back outer layer 12 is a mesh fabric.

[0021] An opening is provided at the top of the garment 1 for the cooling fan assembly 2 to enter and exit the space, and an opening and closing device is provided at the opening, which may be a zipper or Velcro, etc. In this embodiment, the opening is provided on the outer layer 12 of the back, and the opening and closing device is a zipper 121.

[0022] like Figure 4 As shown, the cooling fan assembly 2 includes a gasket 20 and a semiconductor cooling fan 21 detachably mounted on the gasket 20 .

[0023] In this embodiment, two semiconductor cooling fans 21 are provided on the liner 20 , and the cold air outlets of the two semiconductor cooling fans 21 are arranged away from each other.

[0024] A flange 22 is provided on the side of the pad 20 close to the back inner layer 10 for supporting the back inner layer 10 to form a cavity 200. The flange 22 is provided along the edge of the pad 20 to form a closed ring; one or more first bosses 23 are provided in the cavity 200 for supporting the back inner layer 10.

[0025] A hole matching the shape of the semiconductor cooling fan 21 is opened on the gasket 20, and the semiconductor cooling fan 21 is embedded in the hole, and then through the clamping ring 24, a buckle 241 that can cooperate with the semiconductor cooling fan 21 is provided on the clamping ring 24, so that the semiconductor cooling fan 21 and the gasket 20 are tightly connected.

[0026] In this embodiment, the pad 20 is made of foam material, and the flange 22 and the first boss 23 are integrally formed with the pad 20; the cross-section of the flange 22 is arched; the first boss 23 is distributed around the two semiconductor cooling fans 21, and plays the role of supporting the back inner layer 10 to prevent the back inner layer 10 from being adsorbed by the suction force of the fan and blocking the fan.

[0027] like Figure 5 and Figure 6 As shown, the semiconductor cooling fan 21 includes a bottom shell 210 , a fan 211 is provided in the bottom shell 210 , a cooling module 212 is provided on one side of the fan 211 , and an air guide fin 213 is provided on the side of the cooling module 212 away from the fan 211 .

[0028] The fan 211 is a worm gear fan, which has an annular fan blade 2110. A partition 2111 is provided in the radial direction of the fan blade 2110. The partition 2111 can prevent cold air and hot air from mixing at the fan blade.

[0029] A cold air inlet 2101 and a cold air outlet 2102 are provided on the bottom shell 210 , and the cold air inlet 2101 corresponds to the position of the fan blades 2110 .

[0030] The semiconductor cooling fan 21 further includes a top shell 214 , on which a hot air inlet 2141 and a hot air outlet 2142 are provided. The hot air inlet 2141 corresponds to the position of the fan blades 2110 .

[0031] The cross section of the air guide piece 213 is arc-shaped, and the air guide piece 213 has an air inlet end 2131 and an air outlet end 2132 .

[0032] Refrigeration module 212 includes a semiconductor refrigeration plate 2120, which has a cooling surface and a heating surface, both of which are connected to air-permeable heat sink fins. Refrigeration module 212 also includes a thermal insulation layer 2125 covering the heat sink fins. Refrigeration module 212 is a mature existing technology, and its specific structure is not detailed here.

[0033] The air inlet end 2131 of the air guide plate 213, the semiconductor cooling plate 2120 and the partition plate 2111 of the fan blade 2110 are arranged on the same plane. In this embodiment, when working, the side of the refrigeration module 212 close to the bottom shell 210 is cooling, and the side close to the top shell 214 is heating. The fan blade 2110 of the fan 211 rotates after being powered on. Due to the provision of the partition plate 2111, the air entering the fan 211 from the cold air inlet 2101 and the hot air inlet 2141 is not easy to mix. A part of the air blown out by the fan 211 is cooled by the cooling surface side of the refrigeration module 212 and then passes through the air guide plate 213 and the cold air outlet 21 02 is blown into the cavity 200; the other part of the wind blown out by the fan 211 takes away the heat on the heating surface side of the refrigeration module 212 and is discharged from the hot air outlet 2142; the cold air blown out from the cold air outlet 2102 exchanges heat with the human body in the cavity 200, and is then sucked into the refrigeration module 212 from the cold air inlet 2101 by the fan blades 2110 for cooling, and then discharged from the cold air outlet 2102. The cold air forms a cycle in the cavity 200 and the semiconductor refrigeration fan 21, and is not easily discharged through the semiconductor refrigeration fan 21, and the hot air outside the semiconductor refrigeration fan 21 is not easy to enter the above circulation loop.

[0034] Figure 7 A represents the cold air circulation loop; B represents the hot air dissipation path.

[0035] The air whose temperature rises after heat exchange with the human body is again sucked into the semiconductor cooling fan 21 from the cold air inlet 2101 by the fan 211 for cooling. Since the air temperature in the cavity 200 is lower than the air temperature outside the clothes 1 at this time, the temperature of the air in the cavity 200 will be lower after cooling by the semiconductor cooling fan 21, and the cooling effect will be better. Since the cold air of this structure is not easily dissipated to the environment outside the clothes 1, no waste will be caused, so the utilization rate of electric energy will be higher.

[0036] like Figure 5 As shown, in order to prevent the fan 211 from directly sucking the cold air blown out of the cold air outlet 2102 through the cold air inlet 2101, a second boss 2105 is provided on the outside of the bottom shell 210 and between the cold air inlet 2101 and the cold air outlet 2102 for isolating the cold air inlet 2101 and the cold air outlet 2102 and supporting the back inner layer 10.

[0037] Typically, the top shell 214 and the bottom shell 210 are formed by plastic injection molding, and the second boss 2105 is integrally formed with the bottom shell 210 .

[0038] The top shell 214 and the bottom shell 210 are connected by snap fastening and then fastened by screws.

[0039] like Figure 1 and Figure 2As shown, in order to further improve the cooling effect of the air-conditioning clothing and prevent the cooling effect of the front part of the air-conditioning clothing from being poor, a cooling unit 3 is provided on each of the left and right sides of the lower front part of the clothing 1.

[0040] A cooling unit installation hole is provided on the left and right sides of the lower front portion of the garment 1; Figure 8 and Figure 9 As shown, the refrigeration unit 3 has a mounting portion 31, which includes a protruding portion 311 and a resisting portion 312. The refrigeration unit 3 also has a contact portion that contacts the human body and a fixing member 32 for fixing the refrigeration unit 3 on the pad 11. During installation, the protruding portion 311 passes through the refrigeration unit mounting hole; the resisting portion 312 abuts against the outside of the clothes, and the fixing member 32 abuts against the inside of the clothes.

[0041] Refrigeration unit 3 also includes a fan 33, cooling fins 34, and a cover 35. When cooling fins 34 are in operation, the cooling energy is transferred to the cover 35, which contacts the human body and transfers the cooling energy to the human body. Heat generated by cooling fins 34 during operation is removed by fan 33. Providing cooling unit 3 at the front of garment 1 compensates for the defect that the cold air from cooling fan assembly 2 cannot cool the front of the human body, thereby improving the cooling effect of the air-conditioned garment.

[0042] The specific structure of the refrigeration unit 3 is described in detail in other patent documents of the company, and its specific structure will not be repeated here.

[0043] like Figure 1 and Figure 2 As shown, a pocket 13 for accommodating batteries and a wire restraint belt 14 are provided on the front chest of the garment 1. The power cords 36 of the cooling fan assembly 2 and the cooling unit 3 can pass through the wire restraint belt 14 and then enter the pocket 13 to be connected to the power supply.

[0044] This solution can gather cold air, achieve high cold air utilization, good cooling effect, and good electric energy utilization.
