備してなることを特徴とするやぐらこたつ。 In Yagura Kotatsu, the inside of the Yagura Kotatsu is heated by an electric heating part that generates heat when electricity is applied.
A first heat sensing element that senses a change in the temperature of the electric heating section, and a first heat sensing element that detects a change in the heating temperature inside the Yagura Kotatsu main body by providing a first heat sensing element in a place where the heating temperature within the Yagura Kotatsu main body by the electric heating section is relatively slow to rise. A second heat-sensitive element detects the temperature, and the temperature of the electric heating part is energized based on inputs from the first heat-sensitive element and the second heat-sensitive element. Initially, the temperature is relatively high, and thereafter the temperature inside the tower kotatsu approaches the set temperature. The tower kotatsu is characterized by comprising a control circuit that controls the supply of electricity to the electric heating part such that the electricity is gradually lowered as the temperature increases.
