Electric cooker temperature control assembly, electric cooker with same and temperature control method

Abstract

The invention provides an electric cooker temperature control assembly, an electric cooker with the same and a temperature control method. A power failure reset snap-action type temperature controller and a simple structure can be used for achieving the functions of temperature limitation, thermal insulation and dry burning prevention of the electric cooker. The electric cooker temperature control assembly comprises the power failure reset snap-action type temperature controller and a heat conduction cover, the open portion of the heat conduction cover extends outwards to be provided with a skirt edge, the power failure reset snap-action type temperature controller is fixed inside the heat conduction cover, the temperature-sensing face of the power failure reset snap-action type temperature controller is tightly attached to the inner top face of the heat conduction cover, and an elastic component is arranged on the lower portion of the heat conduction cover. The electric cooker with the temperature control assembly further comprises a heating disc and an electric cooker inner container, a heat conduction cover installing hole is formed in the heating disc, the heat conduction cover penetrates upwards through the heat conduction cover installing hole, the elastic component abuts against the skirt edge of the heat conduction cover so that the skirt edge of the heat conduction cover can make tight contact with the heating disc, and a heating element of the power failure reset snap-action type temperature controller is connected with a movable contact-fixed contact loop in parallel and then connected with the heating disc in series into a power loop of the electric cooker.

Description

technical field [0001] The invention relates to the technical field of household appliances, in particular to an electric rice cooker temperature control assembly, an electric rice cooker using the temperature control assembly and a temperature control method. Background technique [0002] At present, the electric rice cooker controlled by the magnetic steel temperature limiter is widely used because of its simple structure and low price. Pot temperature limit, heat preservation function. However, the magnetic steel temperature limiter has defects such as fragility, insensitivity to temperature, and large temperature tolerance. Debugging also requires more human resources; there is currently a more stable and safer power-off reset jump thermostat with temperature limit. The temperature of the circuit is limited. At this time, the heating element is energized to generate heat, so that the temperature of the bimetal is kept above the reset temperature. The contacts remain o...

However, the magnetic steel temperature limiter has defects such as fragility, insensitivity to temperature, and large temperature tolerance. Debugging also requires more human resources; there is currently a more stable and safer power-off reset jump thermostat with temperature limit. The temperature of the circuit is limited. At this time, the heating element is energized to generate heat, so that the temperature of the bimetal is kept above the reset temperature. Contacts remain open under power and reset after power failure

However, the current power-off reset jump thermostat is only used for accidental overheating protection
