Abstract
The utility model relates to a connecting line structure of the safe cares of a quick electric water heater with better property of preventing electric shock, which comprises a water inlet, a water-inlet safe care, a heating wire, a heating main body, an upper end cover of the heating body, an upper rubber cushion of the heating body, a lower end cover of the heating body, a lower rubber cushion of the heating body, a leading-out bar of a zero line, a sealing ring of the leading-out bar, a leading-out bar of a live wire, a connecting piece, a binding post of the zero line, a water-outlet safe care and a water outlet. The connecting line structure of the safe cares of the quick electric water heater with the better property of preventing the electric shock is characterized in that the binding post of the zero line is positioned in a water channel of the water-outlet safe care and is also connected with the zero line of a power supply. By the connecting line structure, the property of preventing the electric shock is greatly reinforced on the basis of the insulation of an original safe care, so that the water inlet and the water outlet are both at a zero potential. Even if no grounding wire is arranged in a power grid, the safety can be ensured as long as the connection of the zero line and the live wire is correct, and no injury can be caused to a human body.
Description
Technical field
The present invention relates to the electric heater field, be specifically related to the connecting line construction of the anti-electric wall of quick electric water heater.
Background technology
At present anti-electric wall technology is widely used on quick electric water heater, especially in the direct-fired electric heater of heater strip, use in the majority, heater as practicality novel 200820083537.9, the water route of certain distance is set respectively in the intake-outlet position of heater exactly, thereby utilize water to come decay current and reach the effect of anti-electric wall, simultaneously heater strip is arranged on and bubble can not gathered on heater strip and burns silk as resistance.But there is defective in this kind structure, because connecting the metal connection post of heater strip is connected with zero line with the live wire of power supply, so one of them must be connected the anti-electric wall of its water inlet or water side with the live wire of power supply, because live wire is a high voltage, so there is high voltage in the end of the anti-electric wall of water inlet or water outlet, the entery and delivery port of water heater all is provided with earth connection, and general resident's electrical network all has earth connection, even if electric current leaks, also can lead away, so can be not dangerous to the person with the electrical network ground wire.And, have only two lines of zero line and live wire to may not having earth connection in part grown-ups and children district or its electrical network of interim room, if water heater makes the leakage current of entery and delivery port bigger than normal owing to anti-electric wall lost efficacy, electric current will flow through human body gets an electric shock the people, causes injures and deaths.Therefore also need improve this kind structure, make its protection against electric shock performance better, safer.
Summary of the invention
Technical problem to be solved by this invention is to improve on above-mentioned prior art present situation basis, at there not being earth connection in the electrical network, but as long as zero, live wire connects and correctly just can guarantee safe anti-electric wall connecting line construction.
The present invention solves the problems of the technologies described above the technical scheme that is adopted: the connecting line construction of this anti-electric wall, comprise on water inlet, the anti-electric wall of water inlet, heater strip, heating main body, calandria upper end cover, the calandria rubber cushion, zero line eduction rod, eduction rod sealing ring, live wire eduction rod, brace, zero line binding post, the anti-electric wall of water outlet and delivery port under rubber cushion, calandria bottom end cover, the calandria, it is characterized in that: the described binding post that is connected with zero line is arranged in the water route of the anti-electric wall of water outlet, and links to each other with zero-power line.
The present invention when the anti-electric wall connecting line construction of design, the binding post that the fixedly position of live wire eduction rod and zero line eduction rod, and design is connected with zero line, the water-in and water-out of assurance heating arrangement prevent that the end of electric wall all is positioned at the zero potential position, thereby assurance safety.Should improve on the prior art basis by anti-electric wall connecting line construction, the protection against electric shock performance is better, guarantees safety.
Description of drawings
Fig. 1 is the expansion schematic diagram of the utility model embodiment;
Fig. 2 is the utility model embodiment exploded view.
The specific embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
As depicted in figs. 1 and 2, should comprise calandria bottom end cover 16 by anti-electric wall connecting line construction, on the described calandria bottom end cover 16 water inlet 1 is set, the anti-electric wall 13 of water inlet is set in the described heating main body 3, electric wall 5 is prevented in water outlet, heater strip 2, described heater strip 2 two ends are provided with live wire eduction rod 7 and zero line eduction rod 11, described live wire eduction rod 7 is connected with calandria bottom end cover 16 with zero line eduction rod 11, realize sealing by eduction rod sealing ring 12 and calandria bottom end cover 16, in the water route of the anti-electric wall 5 of the water outlet of described heating main body 3 binding post 6 that is connected with zero line is set, the described binding post that is connected with zero line 6 links to each other by brace 9 with zero-power line 10, and it is fastening by brace hold-down nut 15, rubber cushion 18 on the rubber cushion 17 and calandria is set between described heating main body 3 and calandria bottom end cover 16 and the calandria upper end cover 19 under the calandria, and is fastenedly connected and seals by fixed screw 20 on fixed screw 21 and the calandria under several the calandrias.
Running water enters the water route that electric wall 13 is prevented in the water inlet on the heating main body 3 from water inlet 1 by calandria bottom end cover 16, and heater strip 2 will be crossed the anti-electric wall 5 of water outlet of flowing through after water heats, and is flowed out by the delivery port 4 that is arranged on the calandria upper end cover 19 afterwards.
Electric current flows to zero-power line 10 by zero line eduction rod 11 by power firestreak 8 after live wire eduction rod 7 is by heater strip 2, described zero line eduction rod 11 links to each other with zero-power line 10, be positioned at into anti-electric wall 13 1 ends of water, so anti-electric wall 13 1 ends of water inlet are zero potential, described live wire eduction rod 7 links to each other with power firestreak 8, is positioned at anti-electric wall 5 one ends of water outlet, and the described binding post that is connected with zero line 6 links to each other with zero-power line 10, be positioned at anti-electric wall 5 one ends of water outlet, so guarantee that anti-electric wall 5 one ends of water outlet also are zero potential.So do not have at electrical network under the situation of ground connection, the voltage between intake-outlet and the human body all is zero, thereby increases degree of safety, and this kind connecting line construction is on the basis of original anti-electric wall, and the protection against electric shock performance is better, and is safer.
