Heating unit, electric heating furnace with same, and heating device used on table

Abstract

The invention discloses a heating unit, an electric heating furnace with same, and a heating device used on a table. The invention provides a heating unit which has no loss in heat transfer and does not scald hands or feet when contacting with the hands or feet. At the lower surface of an upper plate (1) with appointed plate thickness and rigidity guarantee and from the lower surface side, the heating unit comprises a heat insulator (4), a membranous reflection part (5) used for performing heat radiation to the lower side, a heating wire (6) and a part (7) overlapped below the heating wire (6) and made from materials with air permeability. The heat insulator (4), the reflection part (5), the heating wire (6) and the part (7) are combined into a whole to form a surface-shaped heating body (H).

Description

technical field [0001] The present invention relates to a heating unit for heating a heating wire, an electric kotatsu, and a heating device for a table or a desk. Background technique [0002] An example of an apparatus having the heating means is an electric kotatsu. [0003] As for the heating unit included in the above-mentioned electric kotatsu, it is proposed to install it on the lower surface of the upper plate, and to laminate a heat insulating material, an aluminum sheet, a heater, and a vapor chamber made of galvanized steel sheets from the lower surface side. A heating unit (for example, refer to Patent Document 1). [0004] Patent Document 1: Japanese Patent Application Laid-Open No. 9-79580 (refer to Figure 5 , Figure 6 ) [0005] In the above Patent Document 1, although the heat of the heater can be uniformly distributed over a wide range by the vapor chamber, since the vapor chamber is a metal plate, the heat from the heater is transmitted by the vapor ch...

AI Technical Summary

Problems solved by technology

Therefore, there is a problem that the heat of the heater cannot be efficiently transferred depending on the heat transfer efficiency of the metal plate, resulting in loss during heat transfer.

[0006] Also, when the heat from the heater is transferred to the vapor chamber made of metal plates, because the vapor chamber becomes hot, it will be very hot when the hands or feet touch the vapor chamber, so the temperature cannot be adjusted. Raise above the need, so there is still room for improvement
