したものである。 Conventionally, when installing a temperature sensor 1 to prevent overboiling in a bathtub, as shown in FIG. A thermally conductive hollow pipe 8' made of copper or the like with its lower end closed is installed in the water chamber 7 of the gas bath kettle, so that the upper end opening faces the outside air.
Temperature sensors 1 were attached to the top and bottom of this, and the upper end opening was closed with a cap 9. According to this configuration, the water temperature in the water chamber 7 is different between the upper and lower parts, and the lower part of the hollow pipe 8' is relatively low temperature, but the temperature of the air in the hollow pipe 8' increases as heating progresses. Due to the temperature difference, dew condenses on the lower inner surface of the hollow pipe 8', and water droplets accumulate inside the hollow pipe 8'. This has caused negative effects such as corrosion of the hollow pipe 8', electrical short circuit phenomenon, and change in the temperature detected by the temperature sensor 1.
The temperature sensor 1 is a plurality of temperature sensing diodes connected in series and inserted into a bent resin tube.
本案は斯る欠点を解消すべくなされたもので、

を装着したものである。 This proposal was made to eliminate these shortcomings,
As shown in FIG. 2, a thermally conductive hollow pipe 8 with an open lower end is vertically penetrated through the water chamber 7, and a temperature sensor 1 for controlling burner combustion is installed inside the hollow pipe 8.
It is equipped with.

な悪影響を防止できる。 Therefore, according to the present invention, even if water droplets are generated inside the hollow pipe 8, the water droplets are discharged from the lower end without accumulating inside the hollow pipe 8, so that the adverse effects as in the conventional case can be prevented.

を付している。 In the above embodiment, the hollow pipe 8 is brazed to the wall of the water chamber 7 at its upper and lower ends. Further, although a plurality of temperature sensing diodes connected in series is used as the temperature sensor 1, the present invention is not limited to this. Further, when the temperature detected by the temperature sensor 1 exceeds a set value, combustion in the burner 2 is stopped, but it is also possible to control not only ON/OFF of combustion but also the amount of combustion. Furthermore, in FIG. 2, the same parts as in FIG. 1 are given the same reference numerals.
