Embodiment Construction
[0017] Such as figure 1 As shown in the structural diagram of the present invention, an electric heater with double-layer insulation and safety grounding to prevent leakage includes an insulating heat-conducting carrier 4 and a heating element 3 arranged on one side of the insulating heat-conducting carrier. The body 3 is provided with an insulated heat conducting body 2 and a first non-insulated conductor 1 which can be grounded in turn. A wire (not shown in the figure) is connected to the conductor. On the other side of the insulating heat conducting carrier 4, an insulating spacer Thermal body 5 and the second non-insulated conductor 6 that can be grounded, also connect a lead (not shown in the figure) on this conductor, be provided with a cavity in the insulating heat insulator 5, the first non-insulated conductor 1 and the second non-insulated conductor The insulated conductor 6 is connected with the power safety grounding wire by wires. The electric energy expected to l...

The invention discloses a double-layered insulated current leakage preventing electric heater which comprises an insulated heat transfer carrier and a heating body arranged on one side of the insulated heat transfer carrier, wherein the heating body is subsequently provided with an insulated heat transfer body and a first non-insulated conductor which can be grounded; the other side surface of the insulated heat transfer carrier is subsequently provided with an insulated heat insulating body and a second non-insulated conductor which can be grounded; the first non-insulated conductor and the second non-insulated conductor are connected by a lead wire and are connected with a power supply safety grounding wire; and a cavity is arranged in the insulated heat insulating body. The double-layered insulated current leakage preventing electric heater prevents unsafe problems caused by current leakage, achieves good heat insulating effect, can be applied to other electric heating equipment, and is widely applicable to kettles, electric hot pots, electric stoves, bread ovens, hot water pipes and the like.
Description
technical field [0001] The invention relates to an electric heater, in particular to an electric heater with double insulation and safety grounding to prevent leakage. Background technique [0002] Products that use electric energy in daily life, such as electric furnaces, induction cookers, light wave furnaces, heaters, electric heaters, electric heating appliances and other electric heating devices, use electric energy to generate heat, use insulating carrier surface to generate heat, heat loss is small, energy saving, no open flame, safety, Excellent durability, power saving and other benefits have been widely used in heating appliances. However, the traditional electric heating body is heated by an insulating carrier. Since there is no safe grounding, the possibility of electric leakage cannot be ruled out. [0003] Therefore, how to effectively prevent the expected leakage and effectively insulate the electric heater on the insulating carrier is a technical problem to ...
