Embodiment Construction

[0022] As shown in the attached figure, cover the electric heating layer 6-1 tightly with a copper panel and bottom plate, or directly die-cast the electric heating tube in the copper plate, and leave a central circular hole on the whole plate, which is larger than the outer surface of the temperature limiter 7 path. This electric heating layer 6-1 is made up of the electric heating element that upper and lower two layers of insulators isolate, and 3 support pins 6-2 are arranged vertically on the copper base plate, also draws electric heating wire 6-3 on the base plate. The electric heating copper plate heater 6 made in this way is attached to the bottom supporting plate of the heat-conducting sleeve 3, and the bottom supporting plate has a central hole equally, and is made of carbon steel on the periphery of the hole, and is coated with a durable The heat-insulating cup 8 of the warm paint has a raised cup rim, and the cup rim is smooth, and the cup rim is 1mm to 15mm higher...

Abstract

The present invention relates to a purple earthen ceramic electric cooker, and is characterized by that is possesses an electrothermal copper plate heater using copper as thermal conductor, and includes upper cover, purple earther inner container, thermal conducting plate, radiating liner, external shell, heater, temp.-limiting device and heat-insulating cup. The heat-insulating cup set up by using compression springs and mounting pieces is heat-insulated in the central hole by means of tight contact of heat-insulating cup with bottom of inner container so as to limit temp. accurately. Said electric cooker also is equipped with air escape hole, rediating window and hot air flow escape channel to make inner container be heated uniformly, reduce temp. of external shell, raise electric heating power so as to raise cooking quality.

Description

technical field [0001] The invention relates to an electric heating cooker, in particular to an electric rice cooker with a purple sand ceramic inner container. Background technique [0002] The advent of electric rice cookers with purple casserole or ceramic pots as inner pots marks the arrival of a new generation of electric rice cookers. People no longer need to worry about the impact of metal (especially aluminum) inner pots on health, which is in line with people's psychology of advocating health care. , especially the benefits of purple sand tableware to the human body have long been recognized by people. However, due to the small coefficient of thermal expansion of purple sand ceramics, uneven heating and easy bursting, it is difficult to heat the rice cooker to a higher temperature. Its heating method has experienced the evolution process from the jacket heated by the side, to the cast aluminum plate heated by the bottom of the electric heating tube, to the plate he...
