Description

Technical Field

[0001] This application relates to the technical field of temperature control, and particularly to an electric towel rack. Background Art

[0002] An electric towel rack can heat and dry the clothes hung thereon. Currently, when using an electric towel rack to dry clothes, first set the drying temperature of the electric towel rack, and the electric towel rack heats according to the set drying temperature. When it is detected that the set temperature is reached, the electric towel rack stops heating. However, since the temperature of each part of the electric towel rack is uneven and the temperature rise at some positions is too low, if the temperature detection circuit is set at a position with too low temperature rise, the temperature at other positions may have risen to the set temperature, but the electric towel rack is still continuously heating, thus posing a safety hazard of high temperature.
