The invention discloses an all electric melting insulator glass furnace, comprising a molten pool (11), an allocation pool (6) and a feed path (7), wherein, the molten pool is mainly composed of an external wall (3), an insulating layer (4), a lining (5), a furnace top (8) and a furnace bottom (10); the lower part of the molten pool is connected with the allocation pool by a liquid flowing opening (9) and an upper liquid flowing path (12); the allocation pool is connected with the feed path; a charging opening (1) is arranged above the molten pool; electrodes (2) are respectively arranged in the molten pool, the liquid flowing opening, the upper liquid flowing path and the allocation pool at intervals; and the molten pool is vertically arranged, and the cross section of the inner cavity of the molten pool (11) is of an annular regular hexagon structure. The glass furnace does not generate toxic and harmful gas and dust pollution, is favorable for environment protection, and achieves quick, even and pollution-free melting state, thus improving quality such as insulating properties, mechanical strength and the like of a glass insulator, improving the melting rate of a melting furnace, lowering production cost, increasing economic benefit, and being more favourable for environment protection.
