The invention discloses a temperature limiter for an electric heating furnace, the temperature limiter includes an insulated support, Aluminum shell, butterfly-shaped bimetal sheet, push rod, limitingplate, static contact piece, movable contact piece, static contact point, movable contact point, static contact wiring terminal and movable contact wiring terminal, the aluminum shell, butterfly-shaped bimetal sheet and limiting plate are arranged on the upper part of the insulated support, static contact piece and movable contact piece are arranged on the lower part, static contact point is arranged on one end of the static contact piece, and the other end is electrically connected with the static contact wiring terminal arranged in the insulated support; One end of the movable contact pieceis provided with a movable contact point corresponding to the static contact point, and the other end of the movable contact piece is electrically connected with the movable contact terminal arrangedin the insulated support; A guide hole is arranged in the limiting plate, and the push rod is arranged in the inner cavity of the insulated support through the guide hole. The upper end of the push rod abuts against the top of the butterfly-shaped bimetal sheet, and the lower end of the push rod abuts against the movable contact sheet. The temperature limiter of the invention can meet the workingrequirements of the control panel in the existing electric heating furnace, and has the advantages of simple structure and reliable performance.
Description
technical field [0001] The invention relates to the technical field of temperature control in electric heaters, in particular to a temperature limiter for electric heaters. Background technique [0002] With the improvement of people's living standards, the electric heater is currently the most commonly used household heating equipment in winter. It uses high-efficiency and energy-saving heating elements, and is equipped with a computer version for intelligent control. Raise the temperature of the room and create a comfortable indoor temperature for people in the cold winter. In order to expand the market share, the competition among manufacturers of electric heaters is becoming increasingly fierce, which requires continuous improvement of the heating effect of electric heaters. The heating heating elements of the existing electric heaters are mostly provided with heating elements. With the continuous popularization of heating elements, people's requirements for the heatin...
