Electrothermal furnace

Abstract

The invention discloses an electrothermal furnace, which comprises an adiabatic base and a microcrystalline glass plate arranged on the surface of the adiabatic base. The side of the adiabatic base towards the microcrystalline glass plate is provided with a concave hearth surface and a holding cabin used for installing the control system of the electrothermal furnace; a layer of high temperature heating bearing base is arranged on the concave hearth surface; a pair of conducting electrodes is arranged on the center and the peripheral annular diameter of the high temperature heating bearing base; the conducting electrodes are connected with the power control output end of the control system; and electrothermal membrane layers are arranged on the surfaces of the high temperature heating bearing base and the conducting electrodes of the concave hearth surface. The electrothermal furnace has the advantages of reasonable structure, energy saving and environmental protection, uniform heat, high heat conversion efficiency and high heat utilization rate.

Description

【Technical field】 [0001] The invention relates to a stove which converts electric energy into heat energy. 【Background technique】 [0002] At present, the stoves that use electric energy to generate heat on the market mainly include induction cookers, light-wave ovens, and the like. [0003] Because the coil in the induction cooker will produce electromagnetic wave pollution when it is energized, which will affect human health; in addition, the induction cooker relies on the planar coil under the glass-ceramic plate to form an electromagnetic circuit with the pot on it to transfer heat to the glass plate. On the pot, its heat utilization rate is low, and the induction cooker is only suitable for steel or iron pots, not for aluminum pots and other pots. [0004] The light-wave furnace uses two quartz tubes located in the groove of the furnace body to generate heat. , it is equivalent to linear heating, so the light-wave oven realizes local heating to work, the heat of the w...

[0004] The light-wave furnace uses two quartz tubes located in the groove of the furnace body to generate heat. , it is equivalent to linear heating, so the light-wave oven realizes local heating to work, the heat of the whole glass plate is uneven, and the heating speed is relatively slow. When it is used for cooking, the cooking effect may be affected due to insufficient firepower.
