Abstract
The utility model discloses an electric heater with double-layer insulation and electric leakage prevention functions, comprising an insulated heat-conducting carrier, and a heating body arranged at one side surface of the insulated heat-conducting carrier, wherein the heating body is sequentially provided with an insulated heat-conducting body, and a first non-insulated conductor which can be grounded; the other side surface of the insulated heat-conducting carrier is sequentially provided with an insulated heat-isolating 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 leads and then are connected with a power supply safety grounding line; and the insulated heat-conducting body is internally provided with a cavity. The electric heater prevents electric leakage from generating unsafe problems, also achieves good heat-insulating effect, and can be applied in other electric heating equipment, such as kettles, electric chafing dishes, electric ovens, bread toasters, hot water pipes and the like, thus having wide application.
Description
Technical field
The utility model relates to electric heater, relates in particular to a kind of double hyer insulation and have safety ground to prevent the electric heater that leaks electricity.
Background technology
Adopt the product of electric energy in the life, as; Various electric calorifie installations such as electric furnace, electromagnetic oven, light-wave cooker, heating installation, electric heater, electric heating appliance, utilize electric energy heating, adopt little energy-conservation, the flames of anger of the heating of insulating carrier face, thermal loss, fail safe, durability is good, save benefits such as electric power, be applied on the heating appliances by wide model.But traditional electric heating element utilizes the insulating carrier heating because no safety ground can't be got rid of the possibility of easy electric leakage, and safety is also heat insulation inadequately inadequately, scorches desk easily.
Therefore, how effectively to prevent on the insulating carrier electric heater expection electric leakage and effectively heat insulation be a technical problem that needs to be resolved hurrily in the industry.
The utility model content
The utility model is for solving electric heater electric leakage and the heat insulation inadequately technical problem on the existing insulating carrier, the electric heater that a kind of safety ground is provided, improves the double hyer insulation of effect of heat insulation and prevent to leak electricity.
For solving the problems of the technologies described above, the technical scheme that the utility model provides is: the electric heater that a kind of double hyer insulation and preventing leaks electricity, comprise the insulating heat-conductive carrier, be arranged on the heater on this insulating heat-conductive carrier one side, wherein: but first non-insulated conductor that on this heater, is disposed with insulating thermal conductor and ground connection.
Wherein, but second non-insulated conductor that on the another side of described insulating heat-conductive carrier, is disposed with insulation insulator and ground connection.
Wherein, be provided with cavity in the described insulation insulator, be provided with thermal reflecting coating or heat-insulation and heat-preservation cotton in this cavity.
Wherein, described first non-insulated conductor couples together by lead with second non-insulated conductor and is connected with the power safety earth connection.
Wherein, described first non-insulated conductor all or partly covers described insulating thermal conductor.
Wherein, described second non-insulated conductor all or partly covers described insulation insulator.
Wherein, described first non-insulated conductor and second non-insulated conductor are hollow form, planar, netted or other geometrical form.
Compared with prior art, but the utility model is disposed with first non-insulated conductor of insulating thermal conductor and ground connection on heater, but on the another side of insulating heat-conductive carrier, be disposed with second non-insulated conductor of insulation insulator and ground connection, the liquid that the insulation of live part is partly contacted does not directly contact with reinforced insulation, the electric energy transfer that the non-insulated conductor expection is leaked arrives on the ground, having prevented that the unsafe problems that electric leakage produces from taking place; Insulation is provided with that cavity has thermal reflecting coating or the heat-insulation and heat-preservation cotton reaches good effect of heat insulation in the insulator; The utility model can be applied in other electrically heated equipment, be widely used as kettle, electric chafing dish, roaster, bread furnace, hot-water line etc.
Description of drawings
Below in conjunction with drawings and Examples the utility model is made detailed explanation, wherein:
