Abstract

A pot lid assembly configured to cover a pot body. The pot lid assembly comprises a pot lid and a mixing machine. The mixing machine includes an electric motor and a mixing apparatus. The mixing apparatus includes a stirring rod and a plurality of stirring vanes positioned on the stirring rod. The electric motor includes a rotary shaft operatively connected with the stirring rod so that the electric motor can cause the stirring rod to rotate. The pot lid is configured to cover the pot body to form a closed cooking space. When the pot lid is removed from the pot body, the mixing apparatus remains located in the cooking space of the pot body. When the pot lid assembly of the present application is in use, the mixing apparatus remains in the cooking space of the pot body after the removal of the pot lid.

First claim
