Fast energy saving electrothermal dark red pottery cooker

Abstract

A fast and energy-saving purple sand ceramic electric heating pot, which is composed of an upper cover 1, a pot liner 2, a casing 3, a convection cooling cover 4, a heat insulating cover 5, an electric heating tube 6, a heat conducting plate 7, etc., and the heat conducting plate is placed in the heat insulating cover Inside, the exposed electric heating tube is installed on the board, and there is a raised platform on the board. The boss 7-1 and the temperature limiter 8 form a temperature limiting control mechanism. The pot liner 2 is placed on the boss. The distance between the bottom of the pot and the electric heating tube is Above 5mm, the space distance between the pot liner and the heat insulation jacket is less than 10mm, and the distance between the heat insulation jacket and the convection cooling jacket is greater than 2mm, during which air convection is formed from bottom to top, which greatly reduces the temperature of the shell, and can improve the heating temperature and efficiency. Dry burning to 350°C without cracking, saving 30-40% of electricity, and accurate temperature limit, has opened up a wide range of uses for purple sand ceramic cookware.

Description

technical field [0001] The invention relates to an electric heating cooker, in particular to a fast and energy-saving purple sand or ceramic electric heating pot mainly heated by hot air. Background technique [0002] Zisha ceramic cooking utensils with purple casserole or ceramic pot as the inner liner are especially suitable for rice cookers, water pots, soup pots, traditional Chinese medicine health care pots, hot pots, roasting pots, stewing pots, etc. This kind of cooking utensils is favored for its special effects such as health care, sanitation, anti-corrosion, anti-corruption, etc., as well as the advantages of containing trace elements that are beneficial to the human body, so that people can stay away from the potential harm of aluminum cooking utensils to the human body; reduce and Abolishing the processing and application of aluminum metal is also a contribution to environmental protection. [0003] The inventor took the lead in successfully developing and relea...

Problems solved by technology

In the existing related technology, the heating structure is generally heated by the bottom of the heating plate. Although higher thermal efficiency can be achieved, the heating is not uniform. At higher temperatures, the electric heating plate will be deformed. On the one hand, the thermal expansion of the pot Not suitable, on the other hand, there will be thermal deformation stress between the parts in the pot, and the heater is in direct contact with the bottom of the pot, which will inevitably cause the pot to burst, and it is difficult to accurately control the temperature limit

As for the "electric ceramic pot" disclosed in the ZL94211811.1 patent, it is said that "it can make full use of heat and save energy", but it is actually difficult to apply it to products.

Because of the heating method of this structure, through the direct heat conduction between the side heat reflection ring and the shell, once heated, the temperature of the shell will be close to that of the reflective ring, which is very hot (even scalded) and difficult to be used as daily necessities, so that its heating temperature cannot reach Minimum cooking temperature required for cooking rice

In short, solving the problems of uneven heating, easy to burst, difficult to increase the heating temperature, inaccurate temperature control of the temperature limiter, and premature tripping of ceramic electric cookers are still technical defects that have not been completely solved at present, which requires overcoming some technical prejudices , it is necessary to design a new electric heating structure and heating method
