Abstract

The utility model relates to a disk type electric heater. The casing of the heater is a disk-like base, a heat radiation chamber is formed on the base, a similar ring-shaped infrared heating tube is fixed inside the heat radiation chamber, a lower reflecting cover is installed inside the heat radiation chamber below the position corresponding to the infrared heating tube, and a scald-prevention protective net is installed on an opening positioned at the upper part of the heat radiation chamber. The disk type electric heater designs the casing as the disk-like base so as to change the shape of conventional vertical or wall type heaters, and designs the infrared heating tube into the similar ring-shape to fit with the lower reflecting cover thereunder, which radiates the heat reflected from the bottom upwards out of the scald-prevention protective net, so as to increase radiation area, improve heat efficiency and realize 360-degree heating of the heating tube, resulting in uniform heating and improved heating effect. Moreover, the disk type electric heater achieves the desired purpose only by arranging the similar ring-shaped infrared heating tube and the lower reflecting cover in the heat radiation chamber, and has the advantages of simple and reasonable structure, small volume and convenient use.
