Electric furnace with good cooling effect

Abstract

The invention discloses an electric furnace with a good cooling effect. The electric furnace comprises a furnace body; a furnace cavity is arranged in the furnace body; at least one air groove is formed in the furnace body; the furnace cavity is divided into at least two mounting cavities by the air grooves; the bottoms of the air grooves are provided with first air holes communicating with the air grooves in correspondence to the bottom plate of the furnace body; cooling fans are installed on the air grooves; through convection guide of the cooling fans, the first air holes communicate with the mounting cavities; through the structures of the air grooves and the fans, more spaces are provided for the furnace body; the first air holes are directly formed in the bottoms of the air grooves,so that no matter whether the first air holes are air inlets or air outlets, the cooling fans can rapidly communicate with the first air holes, and a cooling task can be rapidly completed; an air collecting cavity has a certain space, so that the effects of buffering and heat relieving can be formed, and cooling is further facilitated; and the air grooves have a certain height, so that the effectof isolating heat of heating assemblies is achieved, and the work and the service life of control assemblies cannot be influenced.

Description

Technical field [0001] The invention relates to an electric furnace, in particular to an electric furnace with good heat dissipation effect. Background technique [0002] At present, electric stoves (such as induction cookers, electric ceramic stoves or other electric heating stoves), such as the technical solution disclosed in Chinese Patent ZL201720614789.9, generally include a heat dissipation fan and a heat insulation wall, and the heat dissipation fan is placed horizontally. The volume of the fan is large, so the number of cooling fans is limited. The cooling circuit is single and the heat dissipation effect is not ideal. Moreover, the cooling fan is set horizontally. First of all, the thickness of the electric furnace cannot be reduced, and the central axis and the tuyere on the side of the furnace body The included angles are even perpendicular to each other, resulting in insufficient air flow, which further affects the heat dissipation effect; in addition, the cooling fan...

Problems solved by technology

[0002] At present, the heat dissipation structure of electric furnaces (such as induction cookers, electric ceramic furnaces or other electric heating furnaces), such as the technical solution disclosed in Chinese patent ZL201720614789. The volume of the fan is large, so the number of cooling fans is limited, the cooling circuit is single, the cooling effect is not ideal, and the cooling fan is installed horizontally, first of all, the thickness of the electric furnace cannot be reduced, and its central axis is in line with the tuyere on the side of the furnace body. The included angle is even perpendicular to each other, resulting in insufficient air flow, which further affects the heat dissipation effect; in addition, the cooling fan directly blows hot air to the countertop where the electric stove is placed, causing the temperature of the countertop to rise rapidly, which is easy to burn or damage the countertop and even cause fire hazards

[0003] In addition, the heat insulation wall and the heat dissipation fan are set separately, which cannot effectively use the space in the furnace body, making the layout of the furnace body cavity more crowded and affecting the heat dissipation effect
