た給湯器の安全装置。 A cutoff valve 3 is inserted into the gas circuit to the gas burner 2 corresponding to the heat exchanger 1, and a heat-sensitive detection means is provided to detect that the temperature inside the casing 10 housing the heat exchanger 1 has become high, In a water heater safety device that closes the shutoff valve 3 based on the output from the heat-sensitive detection means, the bimetal of the heat-sensitive detection means is deformed in response to changes in the temperature of the heat-sensing part, and this deformation causes a switch to be activated. A bimetal switch 11 is activated, and a heat receiving plate 13 with excellent heat conduction is attached to the heat sensitive part, and this heat receiving plate 13 is disposed to face the body of the heat exchanger 1. Device.
