AI Technical Summary

Technical Problem

Existing large rice cookers have a problem where the keep-warm function is disconnected when the lid is open to prevent scalding, resulting in rice cooling down quickly and the taste deteriorating.

Method used

The base, side wall insulation modules and cover insulation modules are connected in series and parallel using electromagnetic switch modules and control terminal modules. Combined with temperature control modules and anti-scalding control modules, the insulation power can be flexibly adjusted to ensure continuous insulation within a safe temperature range.

Benefits of technology

It achieves uniform heat preservation of rice even when the lid is open, extends the heat preservation time, maintains the temperature and taste of rice, reduces the risk of burns, and improves user experience and safety.

Abstract

The utility model relates to a large electric cooker with an optimized heat preservation function. The large electric cooker comprises an electric cooker body, a base heat preservation module, a side wall heat preservation module, a cover body heat preservation module, an electromagnetic switch module, a control terminal module and the like. The electromagnetic switch module is electrically connected with the control terminal module and can control the base and the side wall heat preservation module to be connected in series and the cover body heat preservation module to be connected with the base and the side wall heat preservation module in parallel. The electric cooker body control module is connected with the control terminal module, and a temperature control module is further arranged and can adjust the power of the base and the side wall heat preservation module after the electromagnetic switch disconnects the cover body. The electromagnetic switch is composed of a magnetic element and a magnetic sensitive switch, and the control module is connected or disconnected through attachment or separation. The side wall heat preservation module is formed by stacking a plurality of heat preservation rings around the inner container. In addition, the anti-scald control module is electrically connected with the side wall heat preservation module, the output power of the side wall heat preservation module is controlled within a temperature safety threshold value of 60-80 DEG C, and the heat preservation effect and the use safety are effectively improved.
