Abstract

The utility model relates to a heating plate combined type temperature controller, comprising a heating plate and a temperature control assembly, wherein two connection points are oppositely arranged on the heating plate, the temperature control assembly mainly includes an adjusting portion, an electricity portion and a motion portion, the motion portion moves via an alloy sheet connected with the heating plate, the alloy sheet is a single alloy sheet, the middle of which is bended, and two ends of the alloy sheet are connected with the two oppositely arranged connection points in a bonding manner. The temperature control assembly of the utility model is independent, so with strong compatibility, the temperature control assembly can be easily mounted on a heating plate of an electric iron. As a monometallic sheet with low expansion modular, the key alloy sheet directly moves to start the temperature control assembly by directly using thermal deformation of the heating plate. The motion of the single alloy sheet is synchronous with the temperature of the heating plate, so the problem of overshooting does not exist. The heating plate combined type temperature controller can provide more precise and safe temperature control for household electrical appliances of lightweighting heating plates, and substantially reduces material cost, improving market competitiveness of the product.
