Description
Technical Field
The utility model relates to an electric stove especially relates to a long service life's electric stove.
Background
Electric furnaces are electrically heated devices that achieve the desired process objectives. Compared with a fuel furnace, the heating furnace for converting electric energy in the furnace into heat to heat a workpiece has the advantages that: the atmosphere in the furnace is easy to control, the materials are heated quickly, the heating temperature is high, the temperature is easy to control, and the like. With the development of modern industrial technology, the method is widely applied to multiple fields of families, medicines, chemical industry, metallurgy and the like.
China is the largest export country of electric furnaces, but is limited by foreign technical standards when exporting. Resolution European Union issue (EU)2017/1357 specifies the constraints implemented in the EN 60335-2-9 standard, which are: the standard stipulates that the CE surface temperature rise limit value of products exported to European Union electric heating products is cancelled by a double limit value. That is, the temperature rise measured for all relevant surfaces cannot exceed the limits of table Z101, and even if it does not exceed twice the limits, the application of a "high temperature warning" indication to the relevant surface is not allowed.
However, the shell of the existing electric stove is easily influenced by the electric heating tube, and the temperature is easily increased and exceeds the limit value along with the increase of the using time, thereby not only influencing the use safety, but also influencing the sale.
