도 3에 도시된 바와 같이, 발열장치(200)는 발열장치(200)의 내측에서부터 순서대로 발열장치(200)의 형태를 잡아주는 고정사출물(210)과, 고정사출물(210)과 후술할 발열체(220)를 서로 고정시키는 발포물(230)과, 발열체(220)와, 발열체(220), 발포물(230) 및 고정사출물(210)의 외측을 덮는 감싸기원단(240)으로 구성된다.As shown in FIG. 3, the heating device 200 includes a fixed injection material 210 that holds the shape of the heating device 200 in order from the inside of the heating device 200, a fixed injection material 210, and a heating element to be described later. It consists of a foam material 230 for fixing the 220 to each other, a heating element 220, and a wrapping fabric 240 covering the outside of the heating element 220, the foam 230 and the fixed injection material 210.

고정사출물(210)은 쉬라우드(100) 하부의 형상에 맞게 사출 성형을 통해 형성될 수 있다.The fixed injection material 210 may be formed through injection molding to fit the shape of the bottom of the shroud 100.

고정사출물(210)의 일면에는 개구가 형성되고, 상기 개구로 인해 고정사출물(210)의 내부에는 발포공간(310)이 형성된다.An opening is formed on one surface of the fixed injection material 210, and a foam space 310 is formed inside the fixed injection material 210 due to the opening.

발열체(220)는 탄소사로 구비되어, 복사열을 이용하여 사용자의 신체를 가열할 수 있다.The heating element 220 is provided with carbon yarn, and may heat a user's body using radiant heat.

도 4는 발포 공정을 간략하게 표현한 도면이다.4 is a diagram schematically illustrating a foaming process.

도 4에 도시된 바와 같이, 금형(300) 내에 감싸기원단(240)을 장입한 후 그 위에 발열체(220)와 고정사출물(210)을 배치한다.As shown in FIG. 4, after charging the wrapping fabric 240 in the mold 300, the heating element 220 and the fixed injection material 210 are disposed thereon.

고정사출물(210)은 감싸기원단(240)에 의해 고정사출물(210)의 개구가 덮이도록 배치된다. 즉, 감싸기원단(240)에 의해 발포공간(310)의 개구가 덮인다.The fixed injection material 210 is disposed so that the opening of the fixed injection material 210 is covered by the wrapping fabric 240. That is, the opening of the foam space 310 is covered by the wrapping fabric 240.

발열체(220)는 감싸기원단(240)의 내측면에 접하도록 발포공간(310)의 중앙부에 배치되는 것이 바람직하다.The heating element 220 is preferably disposed in the center of the foam space 310 so as to contact the inner surface of the wrapping fabric 240.

고정사출물(210)의 내측면은 발열체(220)의 외측면에서 일정 간격 이격되게 형성되는 것이 바람직하다.It is preferable that the inner surface of the fixed injection material 210 is formed to be spaced apart from the outer surface of the heating element 220 at a predetermined interval.

즉, 상기 간격으로 인해 감싸기원단(240) 내측면의 일부가 발포공간(310)에 노출된다.That is, a part of the inner surface of the wrapping fabric 240 is exposed to the foam space 310 due to the gap.

금형(300)은 상측 금형(300)과, 하측 금형(300)으로 분리되어, 발열체(220) 및 고정사출물(210)을 원활하게 금형(300) 내에 배치할 수 있다.The mold 300 is divided into an upper mold 300 and a lower mold 300, so that the heating element 220 and the fixed injection object 210 can be smoothly disposed in the mold 300.

금형(300) 및 고정사출물(210)의 일측에 형성되는 주입구(315)를 통해 발포액(230a)을 주입하면, 도 5에 도시된 바와 같이, 발포공간(310)에 발포액(230a)이 채워져 발포물(230)이 형성된다.When the foaming liquid 230a is injected through the injection hole 315 formed on one side of the mold 300 and the fixed injection material 210, as shown in FIG. 5, the foaming liquid 230a is in the foaming space 310 Filled to form a foam 230.

발포물(230)로 인해 고정사출물(210), 발열체(220) 및 감싸기원단(240)은 서로 접착 고정된다.Due to the foam 230, the fixed injection material 210, the heating element 220, and the wrapping fabric 240 are adhesively fixed to each other.
