Novel electric cooker temperature control assembly and electric cooker using same

Abstract

The invention provides a novel electric cooker temperature control assembly which is high in PTC heater heat transfer efficiency and stable in performance.The temperature control assembly comprises a kick type temperature controller, a PTC heater, a support and a heat conduction cover, wherein the upper heat dissipation surface of the PTC heater is tightly attached to the inner top surface of the heat conduction cover, and the kick type temperature controller and the PTC heater are pressed and fixed into the heat conduction cover through the support.The invention further provides an electric cooker using the temperature control assembly.The electric cooker further comprises a heating disc and a liner.A skirt extends outwards from the open portion of the heat conduction cover, an elastic component is arranged on the lower portion of the heat conduction cover, the heating disc is provided with a heat conduction cover installation hole, the heat conduction cover upwards penetrates through the heat conduction cover installation hole, the skirt of the heat conduction cover is sustained by the elastic component so as to be in close contact with the heating disc, and the PTC heater and the kick type temperature controller are connected in parallel and then connected with the heating disc in a power circuit of the electric cooker in series.The electric cooker adopting the temperature control assembly can achieve automatic temperature limitation, heat insulation and dry heating prevention.

Description

technical field [0001] The invention relates to the technical field of household appliances, in particular to a novel temperature control assembly for an electric rice cooker. 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, insensitive temperature sensing, large temperature tolerance, and complicated assembly and debugging; "Pot" proposes that the function of temperature limit, heat preservation and anti-dry heating of the rice cooker can be realized by using the power-off reset jump-type thermostat and a simple structure, but the installation position of the heating element of the temperature control assembly of the rice cooker with this structure Not on the top surface of the heat conduction cover, the heat tran...
