Document Type and Number:
WIPO Patent Application WO/2012/008673
Kind Code:
A1
Abstract:
Provided is a cooker that increases the service life and durability of a service life sensor for the main body coating layer of the cooker, and senses the service life of the main body coating layer so as to give notice of the time for replacement. To this end, the cooker comprises: a main body formed of metal which has a container shape to receive food and heat the bottom surface thereof using a heater, and includes a coating layer on the inner surface thereof; a connection; and a handle including a protrusion for a backup sensor at the end thereof. The connector includes: a frame formed of metal which has a hollow portion therein to connect to the side of the main body; and a sensor for sensing the service life of the coating layer, which has an outer surface painted with a temperature-sensitive paint so as to change color according to the variation in temperature due to heating. The protrusion for a backup sensor is inserted in the hollow portion of the connection and contacts the connection to form a heating area through which heat is absorbed via conduction, and thus, functions as a buffer.
