<p>PURPOSE:To supply a large quantity of hot water at a stabilized temperature by suspending a temperature sensor which has a temperature sensing part at the bottom of a plastic cylinder having a bottom in an elongate and shallow tank from above, and disposing a heater at the bottom of the tank and the lower part of the cylinder with a bottom nearly at the center of the tank. CONSTITUTION:The underside of a heater 5 which is placed in an elongate and shallow tank 1 is disposed alongside the bottom of the tank 4. The outer shell for a temperature sensor 3 is a plastic cylinder with a bottom 1, and a temperature sensing part 2 is placed in the bottomed cylinder 1 with a filling material 7 filling the interior of the bottomed cylinder 1. The temperature sensor 3 is suspended inside the tank 4 from above, the temperature sensing part 2 of it being detached from a heater 5 and placed nearly at the center of the tank 4. Thus, a large quantity of hot water can be supplied at a stabilized temperature, and a leakage of water to the temperature sensing part side can be prevented.</p> |
