Abstract

A cooking pan with temperature display function includes a pan body and a handle. An extra bottom layer is provided at the bottom of the pan body with a metallic plate sandwiched in between the bottom of the pan body and the extra bottom layer. An installation hole is located at a side of the metallic plate with a temperature sensor installed inside the hole. A display unit is placed on the handle while the temperature sensor is connected with the display unit via connection wires. This cooking pan can show the temperature of the bottom of the pan body precisely and quickly, so that the user can control the timing better.

Claims
