본 발명의 충전식 패브릭 손난로는 도 1 내지 도 6에 도시된 바와 같이, 충전식 배터리팩(100), 면상발열천(200), 방열터널(300) 및 제어부(400)를 포함하여 구성된다.1 to 6, the rechargeable-type hand warmer according to the present invention includes a rechargeable battery pack 100, an area heating cloth 200, a heat dissipation tunnel 300, and a control unit 400.

충전식 배터리팩(100)은 휴대용 2차 전지로 충전단자(110)에 의해 충전이 가능하고 방전단자(120)에 의해 스마트폰과 같은 이동통신단말기 등에 전기에너지를 보조적으로 공급할 수 있다.The rechargeable battery pack 100 is a portable rechargeable battery which can be charged by the charging terminal 110 and can be supplementarily supplied with electric energy to a mobile communication terminal such as a smart phone by the discharging terminal 120.

상기 충전식 배터리팩(100)는 충전이 가능한 2차 전지이면 되는데, 예를 들어 양극, 음극, 고분자 전해질을 사용한 분리막으로 이루어지는 리튬계 2차 전지가 사용될 수 있다.The rechargeable battery pack 100 may be a rechargeable secondary battery. For example, a lithium secondary battery comprising a separator using an anode, a cathode, and a polymer electrolyte may be used.

구체적으로, 상기 충전식 배터리팩(100)은 도시된 바와 같이, 충전식 배터리(150) 및 상기 충전식 배터리(150)가 내장되는 케이스(160)를 포함하여 구성될 수 있다.The rechargeable battery pack 100 may include a rechargeable battery 150 and a case 160 in which the rechargeable battery 150 is installed.

면상발열천(200)은 상기 충전식 배터리팩(100)을 감싸며 충전식 배터리팩(100)과 전기적으로 접속해서 전기에너지를 공급받아 발열작용을 한다.The surface heat generating cloth 200 surrounds the rechargeable battery pack 100 and is electrically connected to the rechargeable battery pack 100 to receive an electric energy to exert heat.

상기 면상발열천(200)은 예를 들어 기재로 사용되는 천 및 전극을 포함하여 구성될 수 있는데, 이때 상기 천은 탄소나노튜브가 분산된 용액에 함침되고, 전극은 상기 천을 따라 천에 형성될 수 있다.The planar heating cloth 200 may include a cloth and an electrode, for example, used as a base material. The cloth may be impregnated with a solution in which the carbon nanotubes are dispersed, and the electrode may be formed in the cloth along the cloth. have.

이때, 상기 충전식 배터리(150)와 면상발열천(200)의 사이에는 그립감을 향상시키기 위해 스펀지 등의 쿠션부재(도면에 미도시)가 개재될 수 있다.At this time, a cushion member (not shown) such as a sponge may be interposed between the rechargeable battery 150 and the surface heat generating cloth 200 to improve the grip feeling.

방열터널(300)은 상기 충전식 배터리팩 케이스(160)의 양측면에 대칭으로 형성된 긴 터널로서, 충전식 배터리(150)와 면상발열천(200)의 사이에 공간을 형성해서 방열을 유도하는 긴 터널이다.The heat dissipation tunnel 300 is a long tunnel symmetrically formed on both sides of the rechargeable battery pack case 160 and is a long tunnel that forms a space between the rechargeable battery 150 and the surface heat generating cloth 200 to induce heat radiation .

상기 방열터널(300)은 면상발열천(200)으로부터 발생된 열이 직접적으로 충전식 배터리팩(100)의 온도를 상승시키는 것을 억제하고 충전식 배터리(150)로부터의 발열을 외부로 방출한다.The heat dissipation tunnel 300 suppresses the temperature of the rechargeable battery pack 100 from directly rising due to heat generated from the surface heat generating cloth 200 and discharges the heat from the rechargeable battery 150 to the outside.

구체적으로, 상기 충전식 배터리팩의 케이스(160)는 충전식 배터리(150)로부터의 열을 방출하기 위해 외면을 따라 간격을 두고 여러 개의 방열홀(170)이 길이방향을 따라 길게 천공된다.Specifically, the case 160 of the rechargeable battery pack is formed with a plurality of heat dissipating holes 170 spaced apart along the outer surface thereof in order to discharge heat from the rechargeable battery 150.

그리고, 상기 방열터널(300)은 케이스(160)의 내부공간과 연통하도록 케이스(160)의 외면에 길이방향을 따라 길게 돌출되어 방열공간을 형성하고, 상기 충전단자(110)와 방전단자(120) 등의 구조물이 있는 방향의 일측단이 개방된다.The heat dissipation tunnel 300 protrudes along the longitudinal direction on the outer surface of the case 160 so as to communicate with the inner space of the case 160 to form a heat dissipation space and electrically connect the charge terminal 110 and the discharge terminal 120 And the like are opened.

즉, 상기 방열터널(300)은 충전식 배터리(150)의 열을 충전단자(110)와 방전단자(120) 등의 구조물이 있는 방향을 통해 외부로 원활하게 배출하기 위해 충전식 배터리(150) 방향의 내측 부분(바닥은 개방되고 반대쪽 외측 부분(천장)은 폐쇄되어 있으며 양측단 중에서 일측단(방열출구)은 개방되고 타측단은 폐쇄되어 있는 터널 형태를 이룬다.That is, in order to smoothly discharge the heat of the rechargeable battery 150 to the outside through the direction of the structures of the rechargeable battery 150 and the discharge terminal 120, The inner part (the bottom is opened and the opposite outer part (ceiling) is closed and a tunnel is formed in which the one side (heat radiation outlet) is open and the other side is closed.

이때, 상기 방열터널(300)은 더욱 원활한 방열을 위해 도시된 바와 같이 방열출구로 기능하는 개방된 일측단으로 갈수록 내부공간이 점차 넓어지도록 외측으로 경사지게 돌출되는 것이 바람직하다.In this case, the heat dissipation tunnel 300 preferably protrudes outwardly so that the inner space gradually widens toward one opened end, which functions as a heat dissipation outlet, as shown in FIG.

제어부(400)는 상기 면상발열천(200)의 온열과 충전식 배터리팩(100)의 충전 등을 제어하기 위한 컨트롤러로서, 상기 전극과 전기적으로 연결되어 면상발열천(200)의 온열을 제어한다.The control unit 400 is a controller for controlling the heat of the planar heating cloth 200 and the charging of the rechargeable battery pack 100 and is electrically connected to the electrodes to control the heating of the planar heating cloth 200.

이를 위해, 전원을 켜고 끄기 위한 전원ON/OFF단자(410) 및 충전식 배터리(150)의 충전상태나 면상발열천(200)의 온열상태를 표시하기 위한 LED(420)가 추가적으로 구성될 수 있다.To this end, a power ON / OFF terminal 410 for turning the power on and off and an LED 420 for displaying the charged state of the rechargeable battery 150 and the thermal state of the surface heat generating cloth 200 may be additionally constructed.

상기 전원ON/OFF단자(410)는 누르는 횟수에 따라 면상발열천(200)의 온열단계가 조절되도록 구성할 수 있다.The power on / off terminal 410 may be configured to control the heating phase of the planar heating cloth 200 according to the number of times it is pressed.

상기와 같은 본 발명의 충전식 패브릭 손난로는 외관이 섬유와 스폰지로 구성된 손난로로, 구성이 유연하고 쿠션이 있어서 그립감이 뛰어나고, 장시간 손에 쥐고 있어도 피로감이 작다(기존의 제품은 대부분 하드케이스로 되어 있음).The above-described rechargeable-type hand warmer of the present invention is a hand-warmer having an outer appearance made of fiber and sponge, and has a flexible structure, a cushion, a good grip, and a fatigue feeling even when held in a hand for a long time Lt; / RTI >

그리고, 섬유 커버를 사용하여 온열감이 좋으며, 면상발열체를 적용하여 효율이 높아서 온열감이 높고 장시간 사용이 가능하며 발열면적이 넓다(측면과 전면 전체 발열).And, using the fiber cover, the heat feeling is good, the surface heating element is applied, the high efficiency is high, the heat feeling is high, it can be used for a long time, and the heat generating area is wide (side and whole front heat generation).

또한, 대부분 손난로의 구조상 문제는 발열체와 구조물이 충전지를 싸고 있어서 충전지의 온도가 높아지는 문제가 있는데, 특히 본 발명은 충전지를 면상발열체가 완전히 감싸고 있음에도 불구하고 방열터널 구조를 가지고 있어서 밀폐된 주머니 환경에서도 충전지 배터리팩 온도는 50도를 넘지 않을 수 있다.In addition, most of the problems in the structure of the hand stove are a problem that the rechargeable battery is surrounded by the heating body and the structure, thereby increasing the temperature of the rechargeable battery. Particularly, the present invention has a heat dissipating tunnel structure, The battery pack temperature of the rechargeable battery may not exceed 50 degrees.

통상 배터리팩의 안전한 사용온도는 70도 이하이기 때문에 배터리팩 안전회로는 70도가 넘으면 전원이 차단된다.Since the safe use temperature of a battery pack is usually 70 degrees or less, the battery pack safety circuit is cut off when the temperature exceeds 70 degrees.

따라서, 본 발명은 방열터널 구조가 없는 경우 밀폐된 주머니 조건에서 발열체의 최대온도로 구동시 한 시간 이내에 안전회로의 전원을 차단하여 20 ~ 40분 후에야 비로소 정상 구동을 할 수 있는 기존의 문제점을 해결할 수 있는 것이다.Therefore, the present invention solves the existing problem that the power supply of the safety circuit is shut off within one hour of driving to the maximum temperature of the heating element under the closed bag condition in the absence of the heat radiation tunnel structure, and the normal driving can be performed only after 20 to 40 minutes You can.

본 발명에서 면상발열체 사양의 일 실시예로, Size = 60mm X 160mm X 1mm(두께), 구동전압 5V 0.8A (4W), 최대 발열 온도 = 65℃로 구성할 수 있다.In one embodiment of the specification of the planar heating element in the present invention, it is possible to configure the size = 60 mm X 160 mm X 1 mm (thickness), the driving voltage 5 V 0.8 A (4 W), and the maximum heating temperature = 65 ° C.

또한, 본 발명에서 상기 방열홀(170)과 방열터널(300)의 개수는 필요에 따라 가감(예를 들어 방열홀(170)은 총 4개로 도시하였지만 3개나 5개 이상 천공할 수 있고, 방열터널(300)은 양쪽에 대칭으로 총 2개를 도시하였지만 하나 또는 3개 이상으로 구성)할 수 있음은 물론이다.In the present invention, the number of the heat dissipating holes 170 and the heat dissipating tunnel 300 may be increased or decreased according to need (for example, four heat dissipating holes 170 are shown, but three or five heat dissipating holes 170 may be drilled) The tunnel 300 is shown symmetrically on both sides, but a total of two tunnel 300 may be configured as one or three or more).
