Modes for Carrying Out the Invention

[0008] Hereinafter, specific embodiments according to the present disclosure will be described. However, detailed descriptions that are more than necessary may be omitted. For example, detailed descriptions of well-known matters and redundant descriptions of substantially the same configurations may be omitted. This is to avoid making the following description unnecessarily redundant and to facilitate the understanding of those skilled in the art. The inventors provide the accompanying drawings and the following description so that those skilled in the art can fully understand the present disclosure, and do not intend to limit the subject matter described in the claims thereby. In the following description, the same or similar components are denoted by the same reference numerals. (Embodiment 1)

[0009] First, the overall schematic configuration of the clothes 1 (also referred to as a refrigerated garment) will be described, and then the details of each component will be described.

[0010] (Regarding the overall configuration of the clothes) Hereinafter, the schematic of the clothes 1 in Embodiment 1 of the present disclosure will be described with reference to the drawings. FIG. 1 is a schematic front view of the overall clothing 1 in Embodiment 1, and FIG. 2 is a schematic rear view of the clothing 1. Here, with reference to when the clothing 1 is worn on the body, the left side of the clothing 1 with respect to the center line of the clothing 1 (the line indicated by the fastener 23 in FIG. 1) is defined as the left side, and the right side is defined as the right side. Also, with reference to when the clothing 1 is worn on the body, the side closest to the body is defined as the inner side, and the side farthest from the body is defined as the outer side.

[0011] As shown in FIGS. 1 and 2, the clothing 1 is a vest-type clothing 1 having a front fabric 2 disposed on the front side of the body and a back fabric 3 disposed on the rear side (back side) of the body. The front fabric 2 has a fastener 23 and two pockets 24 on the left and right sides. The back fabric 3 has a cooling unit 5 and two air blowers 20 on the left and right sides. FIG. 3 is a schematic view of the inside of the front fabric 2 and the back fabric 3 in Embodiment 1. As shown in FIG. 3, inside the front fabric 2 and the back fabric 3, there are a cooling unit 5, two air blowers 20, a detachable unit 30, a first belt 40, a second belt 50, a first belt stopper 46, and a second belt stopper 56.

[0012] The cooling unit 5 is disposed at approximately the center of the shoulder on the back of a person, and two air blowers 20 are disposed at the positions of the left and right waists of the person. The cooling unit 5 fits into the detachable unit 30 (details will be described later). Here, since the cooling unit 5 fits into the detachable unit 30 and becomes integrated, in a broad sense, it means a configuration including the detachable unit 30, and in a narrow sense, it means the cooling unit 5 alone.

[0013] As shown in FIG. 2, outside air is sent into the clothing 1 by the two air blowers 20, and the sent-in outside air is discharged outside the clothing 1 by the exhaust fan 7 of the cooling unit 5. In this way, a person's back is cooled. Specifically, it will be described with reference to FIGS. 2 and 8.

[0014] Figure 8 shows the airflow in garment 1 in Embodiment 1. In Figure 2, the solid arrows represent the airflow from the blower fan 20 and the exhaust fan 7 of the cooling unit 5. The dashed line represents the airflow cooled by the metal plate 12 of the cooling unit 5.

[0015] First, we will explain the airflow from the blower fan 20 and the exhaust fan 7 of the cooling unit 5. The cooling fan 20 draws outside air into the garment 1. The air taken in is expelled from clothing 1 mainly through the following three pathways. (1) The air is discharged from the waist to the back, and then from the back to the outside of the garment 1 by the heat dissipation fan 7. (2) The air is discharged from the waist to the back, from the back to the neck, and from the neck to the outside of clothing 1. (3) The air is discharged from the waist to the abdomen, from the abdomen to the chest, from the chest to the neck, and from the neck to outside of clothing 1.

[0016] Next, we will explain the airflow (dotted line) cooled by the metal plate 12 of the cooling unit 5. As shown by the dashed line in Figure 2, 8, the metal plate 12 of the cooling unit 5 cools the air around the metal plate 12. The metal plate 12 cools the air drawn into the garment 1 by the blower fan 20 in the space on the back side of the garment 1 on the inner fabric 3 side. The cooled air moves to the chest and abdominal spaces on the outer fabric 2 side of the garment 1. The air cooled on the outer fabric 2 side and the inner fabric 3 side of the garment 1 is discharged out from the neck. Furthermore, some of the air cooled on the outer fabric 2 and inner fabric 3 sides of garment 1 is expelled to the outside of garment 1 by the heat dissipation fan 7.

[0017] Next, we will explain each component.

[0018] (Cooling unit) Figure 4A is a schematic perspective view of the cooling unit 5 in Embodiment 1, and Figure 4B is a schematic exploded perspective view of the cooling unit 5 in Embodiment 1.

[0019] As shown in Figure 4A, the cooling unit 5 has a cooling unit plate 14 and a housing section 18. The cooling unit plate 14 is positioned on the outside of the cooling unit 5 and holds the housing 18. The cooling unit plate 14 has a handle 15 and an exhaust port 19, and has four engagement holes 16 and four holding parts 17 on its outer circumference.

[0020] As shown in Figure 4B, the cooling unit 5 has a heat dissipation fan 7, a heat exchange plate 8, a Peltier element 9, and a metal plate 12 in its housing section 18. When an electric current flows through the Peltier element 9, the heating section 10 generates heat and the cooling section 11 is cooled.

[0021] The heating unit 10 and the heat exchange plate 8 are in contact, the heat from the heat exchange plate 8 is cooled by the exhaust fan 7, and the heat from the heat exchange plate 8 is expelled from the body by the exhaust fan 7. The cooling unit 11 and the aluminum metal plate 12 are in contact, the cooling unit 11 cools the metal plate 12, and the metal plate 12 cooled by the cooling unit 11 comes into contact with the clothing on the back of the person, thereby cooling the person's back.

[0022] (Detachable unit) Figure 6 is a schematic diagram of the detachable unit 30 in garment 1 of Embodiment 1. The upper right diagram of Figure 6 is an enlarged view of the detachable unit 30. The detachable unit 30 has an inner plate 31 (Figure 6) and an outer plate 32 (Figures 5A, 5B). As shown in Figures 5A, 5B, and 6, the detachable unit 30 is fixed to the back fabric 3 by sandwiching the back fabric 3 between the inner plate 31 and the outer plate 32. The outer plate 32 has four protrusions 34 on its outer surface. The projection 34 is U-shaped and has a hollow portion 35. As will be described later, the retaining portion 17 fits into the hollow portion 35.

[0023] (Method for attaching and detaching the cooling unit and the detachable unit) Figures 5A and 5B will be used to explain how to remove the cooling unit 5 from the detachable unit 30. Figure 5A shows the state in which the cooling unit 5 and the detachable unit 30 are fixed together.

[0024] Initially, as shown in Figure 5A, the hollow portion 35 of the detachable unit 30 and the holding portion 17 of the cooling unit 5 are fitted together. At this time, the projection 34 is located closer to the neck of the back fabric 3 (upper left of the page) than the engagement hole 16, and the engagement hole 16 is open.

[0025] Next, as shown in Figure 5B, the knob 15 is used to move the knob 15 toward the neck side (upper left side of the paper), and the cooling unit 5 is moved until the engagement hole 16 is in the position of the projection 34.

[0026] Finally, by pulling the cooling unit 5 outwards, the cooling unit 5 can be removed from the detachable unit 30.

[0027] This section describes how to attach the cooling unit 5 to the detachable unit 30.

[0028] Conversely to the above, first, as shown in Figure 5B, the engagement hole 16 of the cooling unit 5 is fitted into the projection 34.

[0029] Next, as shown in Figure 5A, the gripping part 15 is used to move the gripping part 15 to the bottom edge side (lower right side of the paper) of the back fabric 3, and the cooling unit 5 is moved to a position where the projection 34 and the holding part 17 are in partial contact.

[0030] Finally, move the cooling unit 5 until it clicks into place, fully engaging the projection 34 and the retaining part 17. In this way, the cooling unit 5 can be attached to the detachable unit 30.

[0031] According to the above embodiment, the cooling unit 5 can be easily attached to or detached from the garment 1 by attaching the cooling unit 5 to the detachment unit 30 or detaching it from the detachment unit 30.

[0032] (Method for attaching and detaching the detachable unit from clothing) Figure 7 shows the state in which the cooling unit 5, the detachable unit 30, and the blower fan 20 have been removed from the garment 1. The upper right of Figure 7 is an enlarged view of the area around the cooling unit opening 60, which will be described later. As shown in Figure 7, garment 1 has a cooling unit opening 60 and a detachable unit opening 61. As shown in the enlarged view of Figure 6, the inner plate 31 has an inner plate hole 38, and the outer plate 32 has an outer plate projection 39. In this case, the outer plate projection 39 penetrates the inner plate hole 38. Next, we will explain how to attach the detachable unit 30 to the garment 1.

[0033] First, insert the outer plate projection 39 (Figure 6) of the outer plate 32 into the detachable unit opening 61 (Figure 7), causing the outer plate projection 39 to protrude from the detachable unit opening 61.

[0034] Next, the protruding outer plate projection 39 and the inner plate hole 38 are fitted together. In this way, the outer plate projection 39 and the inner plate hole 38 sandwich the back fabric 3, allowing the detachable unit 30 to be attached to the garment 1.

[0035] Next, we will explain how to remove the detachable unit 30 from the garment 1.

[0036] First, the protruding outer plate projection 39 and the inner plate hole 38 are disengaged.

[0037] Next, the inner plate 31 is removed from the garment 1.

[0038] Finally, the outer plate projection 39 is pulled out from the detachable unit opening 61, and the outer plate 32 is pulled out from the garment 1. In this way, the detachable unit 30 can be removed from the garment 1. According to the above embodiment, the detachable unit 30 can be easily attached to and detached from the garment 1.

[0039] (Air blower fan) As shown in Figures 2 and 3, the garment 1 is provided with two blower fans 20 and two blower fan supports 21 on the left and right sides. The blower fan supports 21 are made of thick fabric embedded inside the back fabric 3 and support the blower fans 20.

[0040] The blower fan 20 has a blower fan body 26 positioned inside the garment 1. The blower fan body 26 is equipped with a motor and a fan. As shown in Figure 7, the back fabric 3 is provided with a fan through-hole 28 that penetrates the fan support 21. The blower fan body 26 is passed through the blower fan through-hole 28, and the blower fan 20 is fixed to the garment 1.

[0041] (belt) As shown in Figure 3, garment 1 includes a first belt 40 and a second belt 50, and the first belt 40 and the second belt 50 are connected to the inner plate 31 of the detachable unit 30. Specifically, cooling unit holes 29 are provided at the four corners of the detachable unit 30, and the first belt 40 and the second belt 50 are passed through the cooling unit holes 29, thereby connecting the first belt 40 and the second belt 50 to the inner plate 31.

[0042] The first belt 40 and the second belt 50 are arranged like the straps of a backpack, with the first belt 40 going over the person's left shoulder and the second belt 50 going over the person's right shoulder. This allows the person to carry the relatively heavy detachable unit 30 within the garment 1.

[0043] As shown in Figures 3 and 6, the first belt 40 has a first upper belt 41 and a first lower belt 42. The first upper belt 41 passes through a first belt stopper 46 provided on the back fabric 3, so as not to slip down when a person wears the garment 1. The first upper belt 41 has a first concave buckle 44, and the first lower belt 42 has a first convex buckle 45. The first convex buckle 45 and the first concave buckle 44 fit together to form the first buckle 43.

[0044] The second upper belt 51 passes through the second belt stopper 56 provided on the back fabric 3, so as to prevent the garment 1 from slipping down when a person wears it. The second upper belt 51 has a second concave buckle 54, and the second lower belt 52 has a second convex buckle 55. The second convex buckle 55 and the second concave buckle 54 fit together to form the second buckle 53.

[0045] According to the above embodiment, the first belt 40 is passed over one shoulder and the second belt 50 is passed over the other shoulder, allowing the relatively heavy detachable unit 30 to be carried on the back inside the clothing, and the metal plate 12 of the cooling unit 5 to be in close contact with the body (Figure 8). Furthermore, the first belt 40 and the second belt 50 in Figure 3 can be adjusted in length by stretching or shortening them.

[0046] (Embodiment 2) Embodiment 2 is a configuration in which a vest 125 is used instead of the first belt 40 and the second belt 50. Figure 9 is a schematic diagram showing the positional relationship between the garment 1 and the first belt 40 and the second belt 50 when a person is wearing the garment 1 in Embodiment 1. As shown in Figure 9, garment 1 has sleeve openings 120 on the right and left sides for putting a person's hands through. When a person puts on garment 1, the first belt 40 and / or the second belt 50 may overlap the garment sleeve opening 120. In that case, Embodiment 1 has room for improvement, as when a person tries to put their hand through the garment sleeve opening 120, it is blocked by the first belt 40 and / or the second belt 50, making it difficult to put their hand through the garment sleeve opening 120. Embodiment 2 aims to improve upon the above.

[0047] Figure 10 is a schematic diagram of the inside of garment 100 in Embodiment 2, and Figure 11 is a schematic diagram of garment 100 around vest 125. The upper right diagram of Figure 11 is an enlarged view of the area around vest opening 131, which will be described later. As shown in Figures 10, 11A, and 11B, a vest 125 is provided inside the garment 100. The vest 125 includes a vest body 126, a first vest sleeve 130, a second vest sleeve 140, a left vest sleeve opening 132, a right vest sleeve opening 132, and a vest reinforcing member 133. Vest 125 is made of a relatively coarse mesh to prevent the body from getting sweaty, and the outer edge of the mesh is reinforced with vest reinforcement member 133 to maintain rigidity.

[0048] The main body of the vest 126 is a central component of the vest 125 and has a vest opening 131. The area of ​​the vest opening 131 is larger than the area of ​​the metal plate 12, and the metal plate 12 can pass through the vest opening 131.

[0049] The first vest sleeve section 130 (right side) and the second vest sleeve section 140 (left side) are connected to the main body of the vest 126. Each of the first vest sleeve section 130 and the second vest sleeve section 140 has a vest sleeve opening 132 through which a person's hand can be inserted. The widths of the first vest sleeve portion 130 and the second vest sleeve portion 140 are wider than the widths of the first belt 40 and the second belt 50 in Embodiment 1. Furthermore, vest reinforcing members 133 are provided on the outer edges of the first vest sleeve portion 130 and the second vest sleeve portion 140, thereby strengthening the rigidity of the garment 100.

[0050] The garment 100 is provided with two first vest sleeve fasteners 136 on the right side, one at the top and one at the bottom, and two second vest sleeve fasteners 146 on the left side, one at the top and one at the bottom. The first vest sleeve section 130 passes through two first vest sleeve fasteners 136, and the second vest sleeve section 140 passes through two second vest sleeve fasteners 146. In this way, as shown in Figure 9, the first belt 40 and the second belt 50 can be prevented from obstructing the garment sleeve opening 120. Furthermore, one end of the first vest sleeve fastener 136 and the second vest sleeve fastener 146 is equipped with a hook or the like, allowing the first vest sleeve 130 and the second vest sleeve 140 to be easily detached from the garment 100.

[0051] As shown in Figure 11, the vest 125 has four vest connecting members 134 on the outer edge of the vest opening 131. The number of vest connecting members 134 is not particularly limited. The vest connecting member 134 has a hook, and the vest connecting member 134 is passed through the cooling unit hole 29. Then, by folding the vest connecting member 134 back and engaging the hook of the vest connecting member 134, the vest 125 and the detachable unit 30 are connected, and the vest 125 is held on the garment 100 (Figure 10). In this way, the vest 125 can be easily removed from the detachable unit 30, and the vest 125 can be removed and washed.

[0052] Figure 12 is a schematic diagram showing the vest 125 in the closed state in Embodiment 2. As shown in Figure 12, the vest 125 has a first vest buckle 143 on the upper side and a second vest buckle 144 on the lower side. By closing the first vest buckle 143 and the second vest buckle 144, the metal plate 12 can be brought into close contact with the body, as shown in Figure 8. At this time, the metal plate 12 passes through the vest opening 131 and comes into contact with the body without coming into contact with the vest opening 131.

[0053] Figure 13A is a schematic diagram showing the positional relationship between the garment sleeve opening 120 and the vest sleeve opening 132 in Embodiment 2, and Figure 13B is a schematic diagram showing another positional relationship between the garment sleeve opening 120 and the vest sleeve opening 132 in Embodiment 2. Note that the clothing 100 shown in Figures 13A and 13B is laid out with the inside of the clothing 100 spread out on a flat surface such as a desk. In Figures 13A and 13B, the shaded areas represent the overlapping portions of the garment sleeve opening 120 and the vest sleeve opening 132.

[0054] In Figure 13A, the garment sleeve opening 120 is completely contained within the vest sleeve opening 132, and the shaded area is also completely contained within the vest sleeve opening 132. In this state, when a person puts on the garment 100, as shown in Figure 9, they can easily put their hands through the vest sleeve opening 132 and the garment sleeve opening 120 without being obstructed by the first belt 40 and the second belt 50. As a result, a person can easily put on the garment 100.

[0055] On the other hand, Figure 13B shows a state in which the garment sleeve opening 120 and the vest sleeve opening 132 partially overlap (shaded area). In this case, the shaded area is smaller than the shaded area in Figure 13A. In this state, when a person puts on the garment 100, they can bring their hands towards the garment sleeve opening 120 (shaded area), and as shown in Figure 9, they can easily put their hands through the vest sleeve opening 132 and the garment sleeve opening 120 without being obstructed by the first belt 40 and the second belt 50. As a result, a person can easily put on the garment 100.

[0056] (Embodiment 3) Embodiment 3 is a form of exhaust port cover 150 that covers the exhaust port 19 of the cooling unit 5. Figure 14 is a schematic diagram of the exhaust port cover 150 that covers the exhaust port 19 in Embodiment 3. As shown in Figure 14, the exhaust port cover 150 covers the exhaust port 19 and has a pentagonal shape. Hooks are provided at the vertices of the pentagon, allowing the exhaust vent cover 150 to be attached to and detached from clothing 1, 100. Furthermore, the shape of the exhaust port cover 150 is not particularly limited, as long as it covers the exhaust port 19. According to the above embodiment, the exhaust port cover 150 can prevent foreign matter such as dust and dirt from entering the exhaust port 19. Furthermore, when the cooling unit 5 is operating, it prevents the hot air from the exhaust fan from blowing on other people.
