Energy-saving spill-proof mechanical electric rice cooker and energy-saving spill-proof heating circuit thereof

Abstract

The invention discloses an energy-saving spill-proof mechanical electric rice cooker and an energy-saving spill-proof heating circuit thereof, relates to the technical field of kitchen cooking, and solves the technical problems of long rice cooking time, high possibility of spilling of soup and porridge and unstable warm temperature in the mechanical electric rice cooker. A quick-boiling heating circuit in the energy-saving spill-proof heating circuit of the mechanical electric rice cooker comprises a heater H1, a heater H2 and a temperature controller T1 for detecting the top vapor temperature of the electric rice cooker; the temperature controller T1 is connected in series with the heater H1 and connected in parallel with the heater H2; the spill-proof heating circuit comprises a half-power diode D1 and a power adjusting circuit which are connected in series; the power adjusting circuit comprises the heater H1, the heater H2 and the temperature controller T1; the heater H2 is connected in series with the temperature controller T1 and connected in parallel with the heater H1; and an insulation circuit comprises an insulation temperature controller T2, the half-power diode D1 and the heater H1 which are connected in series. The embodiment of the invention is mainly applied to the mechanical electric rice cooker.

Description

Technical field [0001] The invention relates to the technical field of kitchen cooking, in particular to an energy-saving and overflow-proof mechanical rice cooker and an energy-saving and overflow-proof heating circuit. Background technique [0002] Mechanical rice cookers are recognized by more consumers because of their lower prices and occupy a larger share of the rice cooker market. In order to reduce the production cost of mechanical rice cookers, mechanical rice cookers generally use magnetic steel for cooking control instead of real-time control of cooking based on temperature. As long as the temperature of the pan reaches the trigger temperature of the magnetic steel, the mechanical rice cooker will trip. Enter the heat preservation state. In addition, simpler methods are used to achieve heat preservation, such as heating at full power after the temperature drops, and stopping heating after the temperature rises. This heat preservation method is likely to cause the rice...

AI Technical Summary

Problems solved by technology

[0005] In the process of implementing and using the above-mentioned mechanical rice cooker, the inventor found that there are at least the following problems in the prior art: whether it is the rice function or the soup porridge function, the existing mechanical rice cooker uses a heating tube at full power during the rapid heating stage. , Another heating tube half-power method, for the rice function, the existing rapid heating stage can not achieve real rapid heating, resulting in too long cooking time for rice, and for the soup porridge function, the existing rapid heating It is easy to overflow the soup and porridge during the stage

In addition, in the prior art mechanical rice cooker, one of the heating tubes is usually heated at full power during heat preservation, which leads to a rapid rise in temperature during the heat preservation stage, resulting in insufficient stability of the heat preservation temperature.
