Embodiment Construction

[0015] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0016] see Figure 1-Figure 2 , the electric kettle includes a body 1 for holding water and a heating body 2 for heating water in the body. The heating body is made of inorganic non-metallic conductive materials and other carriers through high-temperature sintering. The other carriers include nano Ceramic material and / or glass-ceramic.

[0017] The heating element 2 is in the shape of a disc, which includes a heating layer 2.2 made of inorganic non-metallic conductive material, a thermally conductive insulating layer 2.1 wrapped on the upper part of the heating layer, and a heat insulating insulating layer 2.3 arranged on the lower part of the heating layer. Made of crystal glass. The inorganic non-metal conductive material is ceramic electronic material or rare earth electronic material, and the heat insulation material is ceramic material.

Abstract

The invention discloses an electric kettle, which comprises a kettle body for containing water and a heating body for heating water in the kettle body, wherein the heating body is formed by sintering an inorganic nonmetallic conductive material and a carrier at a high temperature; the carrier comprises a nano ceramic material and / or microcrystalline glass. The heating body of the electric kettle is formed by sintering of the inorganic nonmetallic conductive material and the microcrystalline glass or nano ceramic material at the high temperature, and comprises a heat-conducting insulating layer, a heating layer and a thermal-insulation insulating layer, wherein the outside surface of the heat-conducting insulating layer is sintered and fixed with a layer of metal board or ceramic material. Due to the thermal-insulation action of the thermal-insulation insulating layer of the heating body, a major part of the heat generated by the heating layer in a working process is transferred to the water to be heated in the kettle body through the heat-conducting insulating layer, and thus, the heating efficiency of the product is improved, and energy conservation and environmental protection are realized. Meanwhile, the electric kettle has the advantages of high unit area heat load, small volume, uniform heating on a heat transfer surface, long service life and the like.

Description

technical field [0001] The invention relates to an electric kettle. Background technique [0002] Electric kettle is a very popular small household appliance. At present, the heating principle of traditional electric kettle is based on the working principle of resistance wire heating, which has the advantages of small heat load per unit area, large volume, and uneven heating on the heat transfer surface. , thermal efficiency is not high and other shortcomings. [0003] Chinese Patent Document No. CN201578037U disclosed on September 15, 2010 an electric kettle using a ceramic-metal high-temperature co-fired heating element. On the setter bottom plate and lead out from the electrodes. The structure could be improved. Contents of the invention [0004] The object of the present invention is to provide an electric kettle with simple and reasonable structure, high heat load per unit area, small volume, uniform heat transfer surface, high thermal efficiency and long service l...
