Thermal storage type electric power baking box

Abstract

The invention relates to an electric oven, in particular to a heat-accumulating electric oven which comprises an oven body. An insulating course is arranged outside the oven body, the inner side of the oven body is separated into two parts with the upper half part being a working region and the lower half part being a heat accumulating region, the lower half part comprises a plurality of heat-preserving devices, each of which comprises a refractory corrosion-resistant container, an expansion chamber and an electric heating rod, the expansion chamber and the refractory corrosion-resistant container are communicated, a phase change heat-accumulating material is arranged inside the refractory corrosion-resistant container, and the electric heating rod is embedded in the phase change heat-accumulating material. A resistance wire heating plate is arranged at the upper part of the refractory corrosion-resistant container, and an air inletting fan and an air exhausting fan are arranged at the two sides of the resistance wire heating plate and used for connecting the upper and lower parts. An automatic temperature controlling system is arranged on the outer surface of the oven body and has a plurality of temperature sampling points that are arranged in the working region at the upper part of the oven body. The heat-accumulating electric oven can accumulate a large amount of heat energy during an electricity off-peak period at night, and does not consume electricity and utilizes the stored heat energy for convenient working during an electricity peak period.

Description

technical field [0001] The invention relates to an electric oven, in particular to a regenerative electric oven. Background technique [0002] The rapid development of the national economy has led to a rapid increase in demand for electricity, and the shortage of power supply in some areas has become a bottleneck in the development of the national economy. In 2003, the electricity consumption of the whole society reached 1.884 trillion kwh. In 2004, there was very little room for increasing the utilization hours of existing power generation equipment. Even after considering new installed power generation capacity, there was still a large gap between my country's total power supply and total demand. At the same time, due to the tight supply of electricity and coal; the low water level of some reservoirs; the delay in the construction of power grids, the bottleneck phenomenon of some transmission and distribution networks; and certain uncertainties in water and temperature, t...

In 2004, there was very little room for increasing the utilization hours of existing power generation equipment. Even after considering the new installed capacity of power generation, there was still a large gap between my country's total power supply and total demand

[0004] The existing electric oven only has a baking device, but no heat storage device. It cannot convert the electric energy in the low-valley period into heat energy and store it. It is used in the peak period, which increases the load on the power grid during the peak period.
