Abstract

The invention discloses an adjustable electric cooker contact switch. The adjustable electric cooker contact switch is characterized by comprising a contact holder, a screw set on the contact holder,and an upper fixing sheet and a lower fixing sheet which are mutually spaced. The upper fixing sheet and the lower fixing sheet are separated by a first ceramic washer and are fixed on the contact holder through the screw. A leaf spring is connected with the upper fixing sheet through a fastening element. Mutually corresponding contacts are set on the lower fixing sheet and the leaf spring. The adjustable electric cooker contact switch is simple in structure, convenient in usage and adjustment and high in stability.

Description

technical field [0001] The invention relates to the technical field of electric cookers, in particular to a contact switch for electric cookers. Background technique [0002] At present, the working principle of the electric rice cooker on the market is: when starting to cook, press the switch button with your hand, and its permanent magnet will attract the temperature-sensitive magnet. The contact of the switch is connected, and the electric heating plate is energized to heat. After the water boils, since the temperature inside the pot remains unchanged at 100°C, the temperature-sensing magnet is still attracted to the permanent magnet. Continue heating until the rice is cooked, and the water is absorbed by the rice. When the bottom temperature rises, when the temperature rises to "Curie point 103°C", the temperature-sensing magnet loses its ferromagnetism, and under the action of the spring, the permanent magnet is bounced off, the contacts are separated, and the power sup...
