<P>PROBLEM TO BE SOLVED: To provide a fixation structure of a temperature sensor, which facilitates attachment of the temperature sensor to a pipe. <P>SOLUTION: The temperature sensor 2 attached to a pipe 1 of a water supply pipe and a hot water pipe of a water heater to directly detect, from water or hot water, water supply temperature and hot water temperature. The temperature sensor 2 includes a rod-like sensor part 4 at its front end, the sensor part 4 is supported by a cylindrical tube 5, and a disk-shaped flange 6 is formed at an end of the tube 5. The tube 1 to which the temperature sensor 2 is attached includes a fixation part 7 formed with a penetration hole 8 through which the sensor part 4 penetrates, a tube fitting part 9 to which the tube 5 is fitted, and a flange fitting part 10 to which the flange 6 is fitted, and after the temperature sensor 2 is inserted into the fixation part 7 of the tube 1, by fitting a fixation fitting 3 for pressing the flange 6 into the tube 1, the temperature sensor 2 is fixed to the tube 1. <P>COPYRIGHT: (C)2013,JPO&INPIT |
