Slow cooker

Abstract

The invention discloses a slow cooker. The slow cooker comprises a cooker shell with a power line, and the cooker shell is provided with a control switch and a cooker cavity and is of an integrated structure formed through plastic in an injection molding mode. A thermal insulation ring is arranged at the upper edge of the cooker cavity and provided with a cooker aluminum inner container. A PTC heater is installed at the bottom of the cooker aluminum inner container, is provided with a heat dissipation device in a matched mode and is electrically connected with the power line. Heat dissipation holes are formed in the bottom of the cooker shell. A cooker pottery inner container is arranged in the cooker aluminum inner container, a supporting edge on the cooker pottery inner container and the upper edge of the cooker aluminum inner container are supported by each other, a heating chamber covering the cooker pottery inner container is arranged between the outer peripheral face and bottom wall of the cooker pottery inner container and the inner peripheral face and upper bottom face of the cooker aluminum inner container, air serves as the heat transfer medium in the heating chamber, and an opening of the cooker pottery inner container is provided with a cooker cover matched with the cooker pottery inner container. Because the cooker shell is of the integrated structure formed through the plastic in the injection molding mode and the PTC heater is adopted for constant-temperature heating, the slow cooker has the advantages of being light, handy, beautiful, convenient to use and safe and achieving constant-temperature heating.

Description

technical field [0001] The invention relates to a cooking utensil, in particular to a slow cooker.

Problems solved by technology

However, most of the current slow cookers use metal shells. The metal shells not only have high production costs, but also the internal heat during the cooking process will increase the temperature of the metal shells. The structure needs to be further improved; in addition, some slow cookers also have the disadvantage that the heating temperature is not easy to control. the taste of the food
