Abstract
The utility model relates to a safety type electric heating tube, which belongs to the field of electric heating. The utility model is composed of a metal heat conducting tube 1, insulation heat conducting media 6, a glass tube 4, an electric heating membrane 5, an outer shell 7, etc. The electric heating membrane 5 is directly coated on the outer wall of the glass pipe 4. When the electric heating membrane 5 is switched on a power supply, electric energy is converted into heat energy which is transferred to the insulation heat conducting media 6 through the glass tube 4. The heat energy can be transferred in the heat conducting tube 1 by the insulation heat conducting media 6. The heat energy can be transferred to water 8 which is heated by the heat conducting tube 1. Then, the purpose of electric heating is realized. Due to the adoption of the method of two layer insulation, water and electricity is completely isolated, which solves the safety problem of electric heating components of the existing electric water heater is solved.
Description
The utility model belongs to field of electric heating, particularly a kind of safety electric heating tube.
At present, the electric heater particularly greatest problem that exists of electric heating shower is the Electrical Safety problem, because electric heating element directly immerses in the water tank or pack into through porcelain tube cover heating wire and to immerse water tank in the metal tube, a safety problem is arranged all.Patent 98232786.2 waterproof method is to adopt the temperature resistant rubber material, also has the long-term ageing Problem of Failure.
The purpose of this utility model is by the sealing of welding means instead of rubber, realizes that water power separates fully, obtains a kind of safe electric heater electric heating element.
Below in conjunction with embodiment the utility model is described, accompanying drawing is embodiment of the present utility model.
The utility model is made up of heat pipe 1, top cover 2, seal cover 3, glass tube 4, Electric radiant Heating Film 5, insulated heat-conducting medium 6, shell 7, heat-insulation layer 10, bottom 11 etc., wherein heat pipe 1, top cover 2, shell 7, bottom 11 constitute anti-water chamber, heat pipe 1 is welded into an integral body with top cover 2 and shell 7 waterproof, shell 7 and bottom 11 are connected and fixed by the screw method.Heat pipe 1 is installed on glass tube 4 inner chambers, and filling insulated heat-conducting medium 6, Electric radiant Heating Film 5 directly are coated on the outer wall of glass tube 4 between heat pipe 1 and the glass tube 4, constitutes electric heating conversion and hot transmission path.Thermostat 13 constitutes control overheating protection circuit automatically with overheat protector 14.Heat pipe 1, top cover 2, shell 7 can be metal copper material, aluminium, steel, enamel material.Insulated heat-conducting medium 6 can be a solid, powdery insulating heat-conductive powder, liquid insulating heat-conduction material or liquid conductive phase body and solid mix insulation Heat Conduction Material.Electric radiant Heating Film 5 can be the tin oxide film that mixes, also can be to be with the conduction powder, with glass dust or Heat-Resisting Adhesive is bonding Electric radiant Heating Film of making mutually or resistive film, and wherein, the conduction powder can be graphite powder, carbon black powder, metal powder or conductive compound powder.Glass tube 4 can be Pyrex, also can be quartz glass or pottery and enamel material.Heat pipe 1 can be the single piece of metal pipe, also can be many metal tubes.When the bypass heating is used outside water tank, shell 7, heat-insulation layer 10 bottoms 11 can omit.
When Electric radiant Heating Film is connected with power supply, Electric radiant Heating Film 5 changes electric energy into heat energy, heat energy passes to insulated heat-conducting medium 6 by the tube wall of glass tube 4, and insulated heat-conducting medium 6 is given thermal conductive metal pipe 1 with thermal energy transfer, and thermal conductive metal pipe 1 is given heated water with thermal energy transfer, after water is heated, proportion reduces, and moves upward, and cold water flows into heating tube from the water tank bottom, hot water flows into water tank from heating tube top, the water of water tank is all heated.When Electric radiant Heating Film 5 is damaged, owing to 4 insulation of process glass tube, and through insulation heat-conducting medium 7 reinforced insulations, electrified body and non-electrified body reach more than three millimeters at space length, guarantee safety.Aspect waterproof, adopt top cover 2 and the method that heat pipe 1 and shell 7 waterproof are welded as a whole, solved fully because of joint leaks or seal fails is leaked and caused the failure of insulation problem, obtained a kind of safe and reliable electrothermal film heating pipe.
Accompanying drawing 1 is that the utility model is applied to the middle electrically heated embodiment of water tank.
Accompanying drawing 2 is that the utility model is applied to the outer electrically heated embodiment of bypass of water tank.
1-heat pipe in the accompanying drawing, the 2-top cover, the 3-seal cover, the 4-glass tube, the 5-Electric radiant Heating Film, the 6-insulated heat-conducting medium, the 7-shell, 8-water, 9-seals bottom, 10-heat-insulation layer, 11-bottom, 12-elbow, 13-temperature sensor, 14-overheat protector.
