Abstract

The invention belongs to the field of a ceramic material, and relates to a composite ceramic for the inner container of a rice cooker, and a ceramic inner container. The current rice cooker with the ceramic inner container has the problems of being slow to heat, uneven in heat transfer, frequently cannot boil rice and the like, and the ceramic inner container with better heat transfer property has bad anti-oxidization capability to seriously influence the service life and safety property of the ceramic inner container. In order to overcome the deficiencies of the prior art, the invention provides a ceramic material for manufacturing the inner container, and the ceramic container thereof. The heat diffusion property test and the anti-oxidization property test show that the ceramic material has the advantages of being fast in heat transfer efficiency and strong in anti-oxidization capability, as well as the advantages of being good in safety performance, low in energy consumption, and long in service life when being used for manufacturing the inner container of an electric rice cooker, thus being suitably applied in the field of manufacturing the inner container of the electric rice cooker.

Description

technical field [0001] The invention belongs to the field of ceramic materials, and relates to a composite ceramic material used for making inner pots and the prepared ceramic inner pots and electric rice cookers. Background technique [0002] The liner is a must for household appliances such as rice cookers. However, the traditional liner has low thermal efficiency and short service life, which is not suitable for the development of electrical appliances. The rice cooker liners currently on the market are usually made of aluminum, iron, stainless steel and other materials, but the surface of the rice cooker liners made of these materials must be surface treated and sprayed. When used for a long time, The sprayed coating on the surface will fall off and fade, which is neither hygienic nor beautiful, and does not meet the requirements of people in today's society for environmental protection and health of products. [0003] The ceramic liner has been fired at a high tempera...
