A temperature sensor for use in a heating apparatus is disclosed. The temperature sensor includes a rigid cylindrical body and upper and lower plates disposed at one end of the rigid cylindrical body. A first electrical insulator is interposed between the upper and lower plates and has a recess filled with a second electrical insulator, in which a hot junction of a thermocouple is buried. Since the respective components are just in contact with each other without any bonding therebetween, there arises no stress in the temperature sensor even at high temperatures. Furthermore, even if a short circuit occurs in the thermocouple, data indicating the short circuit is output from the temperature sensor to the control system of the heating apparatus, thereby assuring safety in the operation of the heating apparatus.

Temperature sensor

A heating apparatus comprising a burner including a burner body having an air-fuel mixture chamber and a burner cap formed with a plurality of flame ports, a pan formed with an opening for receiving the burner body, a top plate placed on an upper face of the heating apparatus and a trivet placed on the top plate. The burner cap includes a cylindrical portion formed with an air passage, a convex portion projecting upwardly from an inner face of the cylindrical portion and a cover member formed integrally with an upper portion of the cylindrical portion through the convex portion such that a gap is defined between an upper end of the cylindrical portion and a lower face of the cover member.
