The material of cooking utensils basically eliminated cast iron. Stainless steel panels, non-stick coating materials sprayed on the surface and tempered glass panels occupy an important position in the cooker, and ceramic panels are also outstanding in recent years.

The thermal efficiency of embedded cookers is generally low, and the energy-saving problem has plagued the industry for many years; For embedded stoves with low air inlet burners, when multiple burners work at the same time, CO is not easy to control and the cleaning performance is generally poor. The embedded gas stove with upper inlet burner has less firepower; The temperature of the cooker panel is generally high, and the tempered glass panel bursts from time to time.
