PROBLEM TO BE SOLVED: To provide a structure of a warmer that can warm a hand or a container of food and drink or the like, and can be used for versatility.SOLUTION: The warmer includes: a frame body 1 being formed to a hollow doughnut a heater 2 disposed in the frame body 1 a heat transmission member 3 that is connected with the heater 2 and transmits the heat of the heater 2 to a surface of the frame body 1, and configures a heat dissipation 4 in which the surface temperature of the frame body 1 that disposes the heat transmission member 3 to the inside rises, and which radiates the heat. The heater 2 is disposed in a circumference shape along an inner surface 1a in the frame body 1, the heat transmission member 3 is disposed to an outside surface 1b from an inner surface 1a of the frame body 1 through a top face 1c and a bottom face 1d while connecting with the heater 2, and the heat dissipation 4 composes a hot section by the inner surface 1a. A container for beverage is put in a center part of the frame body 1 where a hole opens, a hand and an article are put on the frame body 1, and the frame body 1 held by a hand, thereby the drink in the container, the hand and the article can be warmed.COPYRIGHT: (C)2013,JPO&INPIT【課題】 手や飲食物等の容器を温めることができる、多用途に利用できる保温器の構造に関する。【解決手段】 中空ドーナツ状に形成された枠体1と、枠体1内に備えたヒータ2と、ヒータ2と接続されて枠体1表面にヒータ2の熱を伝える伝熱部材3とを設け、内側に伝熱部材3を配置した枠体1の表面温度が上昇して放熱する放熱面4を構成する。ヒータ2は枠体1内の内側面1aに沿って円周状に配置し、伝熱部材3はヒータ2と接続しながら枠体1の内側面1aから上面1cと底面1dを経て外側面1bまで配置し、放熱面4は内側面1aが高温部を構成するものである。穴が開いた枠体1の中央部分に飲料用の容器を置いたり、枠体1の上に手や物品を置いたり、枠体1を手で握ったりして、容器に入った飲み物や手や物品を温めることができる。【選択図】 図1
