Embodiment 1

[0018] Such as figure 1 , the novel electric rice cooker temperature control assembly of the present invention, comprises jump type thermostat 1, PTC heater 2, bracket 3 and heat conduction cover 4, the upper cooling surface of PTC heater 2 and the inner top surface of heat conduction cover 4 Closely fit, the bracket presses and fixes the jump-type thermostat 1 and the PTC heater 2 in the heat conduction cover. Compared with the prior art, the novel rice cooker temperature control assembly of the present invention, the heat transfer efficiency of the PTC heater 2 is higher, and it is easier to provide heat energy to realize the heat preservation function of the rice cooker, and it is not easy even in cold weather. Automatic reset, stable performance. The structure and principle of the PTC heater 2 and the jump-type thermostat 1 of the present invention are all existing mature technologies, and will not be repeated here. As a preferred embodiment, the lower heat dissipation s...

Embodiment 2

[0020] Such as figure 2 , and the difference from Example 1 is that the surface of the aluminum cover of the jump-type thermostat 1 is closely attached to the inner top surface of the heat-conducting cover 4, and the bracket 3 passes through the elastic sheet 32 ​​on the upper surface of the bracket 3 and the through hole on the bracket 3 Press and fix the PTC heater 2 and the jump thermostat 1 respectively. In the temperature control assembly of this structure, the heat transfer of the bimetal sheet of the sudden jump thermostat 1 to maintain the temperature needs to be transferred through the heat conduction cover 4. Compared with the implementation of Example 1, a higher PTC heating power is required. And the installation requires more precise positioning. However, the aluminum cover of the jump-type thermostat 1 under this structure is directly attached to the heat-conducting cover 4, and the jump-type thermostat 1 can reflect the electric current through the heat-conduct...

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...
