Abstract

PURPOSE:To correctly control heating element, by providing a temperature sensing element contacted with a heated substance apart from a support member when the heated substance is loaded, and contacted with a part of the support member of the heating element when the heated substance is not loaded. CONSTITUTION:When a heated substance is not loaded to holding frames 2, 3, a holder 7 of a heat sensing element is contacted with one end 5' of a side wall 5 of the frame 2. With this state, the side wall 5 energyzing a heat element 4 is heated, this heat is delivered to the heat sensing element via the member 7 for temperature control. When a tank 1 is loaded, the member 7 contacts the side surface of the tank 1. In this case, if no liquid is contained in the tank, when power is applied to the element 4, the heat element is heated and heat is delivered to the tank 1. Since the tank 1 is contacted with the member 7, temperature control is made with the heat sensing element 6, allowing to avoid abnormal heating of heater.
