AI Technical Summary

Technical Problem

The lever switch structure in existing mechanical rice cookers is complex, which increases assembly difficulty and manufacturing cost, and may lead to failure in heating or stop heating, and even cause fever machine accidents.

Method used

The heating control circuit is adopted, including a series-connected heating thermostat and heating switch. The temperature sensing element and contact switch are built into the thermostat. The automatic heating and disconnection control is achieved through temperature sensing, and the lever switch is cancelled, which simplifies the rice cooker. structure.

Benefits of technology

It improves the working reliability and safety of the rice cooker, simplifies the assembly process, avoids failures caused by deformation and jamming of the lever switch, and ensures the accuracy and safety of heating and stopping heating.

Abstract

The invention discloses a mechanical rice cooker with a simple structure, which belongs to the field of kitchen appliances. The invention solves the serious defect that the rice cooker cannot heat or stop heating due to deformation, jamming and other problems of the lever switch in the existing mechanical rice cooker. The mechanical rice cooker of the invention comprises an inner pot, a heating plate for heating the inner pot and a heating control circuit for controlling the operation of the heating plate. The heating control circuit comprises a heating thermostat and a heating switch connected in series. The heating thermostat is arranged on the heating plate for sensing the temperature of the inner pot. When the temperature of the inner pot sensed by the heating thermostat reaches or is higher than a set heating disconnection temperature, the heating thermostat is disconnected. When the temperature of the inner pot sensed by the heating thermostat reaches or is lower than a set heating reset temperature, the heating thermostat is reset and turned on. The invention cancels the lever switch in the prior art, thereby improving the working reliability and safety of the rice cooker.
