Abstract: The present invention discloses an electric slow-stewing cooker which has three heating modes, namely high-temperature mode, low-temperature mode and keep-warm mode. The electric slow-stewing cooker of the present invention comprises an upper cover, a cooking container, a barrel-like housing, a base, a control panel, heating elements, a control circuit board (PCB) and a manual switch used for controlling the heating elements, and a power supply unit. The heating elements are divided into two portions with one portion being electrically connected to the manual switch to perform the function of the keep-warm mode and the other portion being electrically connected to the control circuit board to perform the function of both the high-temperature mode and the low-temperature mode.

Abstract: A low cost and low surface temperature stewpot for slow cooking includes a lid, an inner layer, an outer layer, a heater, a housing unit and a bottom plate. The outer layer is placed inside of the housing unit, and the inner layer is placed inside of the outer layer; the lid is on top of the inner layer. The heater is installed at the exterior side of the outer layer, and the bottom plate is at the bottom of the housing unit. The outer layer has a shallow tray structure; the housing unit bottom is of annular shape with an open at the center and an “R angle” circular transition at the connection of the bottom and the side of the housing unit; the outer layer is fastened to the bottom of the housing unit.
