Abstract

Official abstract text for this publication.

A radiant heater device for generating a radiant heat, includes a substrate portion having a plate shape and made of an electrically insulating material, a surface member having a sheet shape and disposed on one surface side of the substrate portion, and a heat generation portion formed on the other surface side of the substrate portion. The surface member is formed of a fiber fabric that is provided with a space portion recessed toward the substrate portion in a thickness direction of the surface member and that restricts a heat transfer in a surface direction of the surface member by the space portion.

First claim

Opening claim text (preview).

The invention claimed is: 1. A radiant heater device for generating a radiant heat, comprising: a substrate portion having a plate shape and made of an electrically insulating material; a surface member having a sheet shape and disposed on one surface side of the substrate portion; and a heat generation portion formed on the other surface side of the substrate portion, wherein the surface member is formed of a fiber fabric that is provided with a space portion recessed toward the substrate portion in a thickness direction of the surface member, the fiber fabric is in contact with the substrate portion, the fiber fabric has a mesh shape, and the fiber fabric has a double mesh structure in which two knitted fabrics are superposed on each other. 2. The radiant heater device according to claim 1 , wherein the fiber fabric is formed of a nonwoven fabric. 3. The radiant heater device according to claim 1 , wherein the mesh shape is a lattice shape. 4. The radiant heater device according to claim 1 , wherein the mesh shape is a honeycomb shape. 5. The radiant heater device according to claim 1 , wherein the fiber fabric is formed by interposing air between a plurality of fibers. 6. A radiant heater device for generating a radiant heat, comprising: a substrate portion having a plate shape and made of an electrically insulating material; a surface member having a sheet shape and disposed on one surface side of the substrate portion; and a heat generation portion formed on the other surface side of the substrate portion, wherein the surface member is formed of a fiber fabric that is provided with a space portion recessed toward the substrate portion in a thickness direction of the surface member, the fiber fabric is in contact with the substrate portion, and the heat generation portion has a structure to restrict a heat transfer in a surface direction of the substrate portion. 7. A radiant heater device for generating a radiant heat, comprising: a substrate portion having a plate shape and made of an electrically insulating material; a surface member having a sheet shape and disposed on one surface side of the substrate portion; and a heat generation portion formed on the other surface side of the substrate portion, wherein the surface member is formed of a fiber fabric that is provided with a space portion recessed toward the substrate portion in a thickness direction of the surface member, the fiber fabric has a mesh shape, and the fiber fabric has a double mesh structure in which two knitted fabrics are superposed on each other.
