A flashing adjustable thermostat

Abstract

The invention discloses a flashing type adjustable temperature controller, comprising a bottom plate, a bimetallic strip, a ceramic ring I, a moving contact group, a ceramic ring II, a static contact group and a temperature adjusting mechanism, wherein the ceramic I, the static contact group, the ceramic ring II, the moving contact group and the temperature adjusting mechanism are mounted on the bottom plate from top to bottom through a long rivet, the ceramic ring I is a double-hole ceramic ring, one mounting hole of the double-hole ceramic ring is mounted on the bottom plate, the other hole of the double-hole ceramic ring is mutually connected with the bimetallic strip through a short rivet, and one end of the bimetallic strip is connected with the moving contact group through a ceramic rod. According to the flashing type adjustable temperature controller, the original single-hole ceramic ring is changed into the double-hole ceramic ring; the the double-hole ceramic ring separates the bimetallic strip from the bottom plate, the temperature adjusting mechanism and the moving and static contact groups and then is mounted at the bottom of an electric heating device alone with screws; therefore, heat conduction of other parts to the bimetallic strip can be reduced greatly so that the temperature of the bimetallic strip gets closer to temperature at a temperature detecting point, namely the sensitivity and accuracy of the temperature controller are improved.

Description

technical field [0001] The invention relates to a temperature controller used on an electric kettle, in particular to a flashing adjustable temperature controller. Background technique [0002] The commonly used flashing adjustable thermostat is a thermostat with a temperature-sensing bimetal as a temperature-sensing element. The bimetal sheet is bent and deformed due to temperature changes, which in turn causes the flashing closure or separation of the movable contact and the static contact. refer to figure 1 , the commonly used flashing adjustable temperature controller includes a bottom plate, a ceramic ring, a bimetal, a moving contact group, a static contact group, and a temperature adjustment mechanism, etc., and the bimetal, ceramic ring, static contact group , the moving contact group and the temperature adjustment mechanism are installed on the bottom plate through rivets from top to bottom in turn. The rivets are also mounting seats. The screws pass through the r...

AI Technical Summary

Problems solved by technology

When measuring temperature, because the rivet, base plate and temperature adjustment mechanism are all made of metal materials, they are good conductors of heat, and heat conduction will occur between them and the bimetal sheet, especially when the electrical power to be measured is large and the temperature rises quickly. , the bimetal is more affected, and the response is even more lagging
