Abstract

The invention relates to an electric heating furnace. The electric heating furnace comprises a furnace body, a cooling fan, a main control panel, a panel and a bottom plate, wherein the panel and thebottom plate are arranged at the upper part and the lower part of the furnace body respectively; a heating piece and a heat energy recovery cover are arranged in the furnace body; the heating piece ispositioned below the panel; an opening is formed in the top of the heat energy recovery cover, and a heat insulation cavity is formed to cover the periphery of the heating piece; an air flowing channel is formed among the heat energy recovery cover, the furnace body and the bottom plate and communicates with the heat insulation cavity; and the cooling fan is used for pumping air outside the furnace body into the air flowing channel, then guiding the air into the heat insulation cavity, dissipating heat of the heating piece and guiding and transferring heat leaked outwards by the heating pieceto the panel. Through the improvement, the air flow direction can be more reasonable and more accurate, the influence of heat on all members except the panel is reduced, heat leaked and lost by a heating body can be transmitted to the panel to the maximum extent and acts on a heated body, heat loss is reduced, and the heat utilization efficiency is improved.

Description

technical field

[0001] The invention relates to an electric furnace. Background technique

[0002] The types of electric stoves on the market include electric ceramic stoves, induction cookers, etc. Conventional electric furnaces have panels and heating components arranged on the panels. When the heating components work, heat will leak and radiate into the main body of the electric furnace. Since the main body of the electric furnace is also equipped with electrical components such as circuit boards, the circuit boards are placed in the main body of the electric furnace. The working life will be shortened in a high-heat environment. Therefore, a cooling fan or a heat shield covering the heating element is usually installed in the electric furnace.

[0003] For example, the Chinese Patent Document No. CN110056916A disclosed on July 26, 2019 a multi-functional household electric heating furnace, which includes a shell, the upper surface of which is provided with a heating are...
