Abstract
The utility model relates to an electricity anti-leakage device of an electric water heater, which comprises a metal junction (2) of which the two heads are all internal screw threads and an insulation junction (3) of which at least one head is external screw threads, wherein, one head of the metal junction (2) is in threaded connection with the insulation junction (3), and the other head is used for being in threaded connection with the junctions of an inlet and an outlet pipes (11) of the electric water heater. The other head of the insulation junction (3) is used for connecting an externally connected water pipe (4). Of course, the insulation junction (3) is preferred that two heads are all external screw threads so that the insulation junction (3) can be conveniently in threaded connection with the original externally connected water pipe (4). The utility model realizes the electricity anti-leakage function by the method that the insulation junction is additionally arranged between the electric water heater and the externally connected water pipe. The insulation junction is arranged in the metal junction skillfully through the metal junction of which the two heads are both internal screw threads. Thereby, in the winter, a metal pipe junction arranged on the electric water heater and the metal junction which is additionally arranged both carry out cold shrinkage, and the insulation junction arranged in the electric water heater is caused to be coated more tightly. Thereby, the water leakage between the metal junction and the insulation junction are thoroughly prevented.
Description
Technical field
The utility model relates to the anticreeper of a kind of parts of electric heater, particularly a kind of electric heater.
Background technology
The inner bag of existing electric heater is a cylindrical shell, in cylindrical shell, be provided with electrothermal tube or other electric calorifie installations, during use, by electrothermal tube or other electric calorifie installations with the water heat temperature raising in the cylindrical shell, be provided with water inlet and delivery port in the lower end of cylindrical shell, and be provided with thereon that to extend to cylindrical shell outer and be carved with externally threaded pipe joint (also can be the overhanging end of water inlet pipe and water outlet pipe in the cylindrical shell), be used to connect outer water tube; Usually, the cylindrical shell of electric heater is metal materials such as stainless steel, and pipe joint also is a metal material, and it is welded on the entery and delivery port of cylindrical shell or links to each other with inlet tube and outlet tube in the cylindrical shell.Though, existing electric heater all is provided with anticreeper at its electric control part branch, but be anti-contingency, the countries concerned's standard code, metal parts such as the cylindrical shell of electric heater, water inlet pipe and water outlet pipe joint must link to each other with the earth connection in the power supply, like this, use under the situation normal, even electric heater generation electric leakage accident, electric current also can directly import the earth by the earth connection in the power supply, thereby guarantees user's personal safety.Yet, because historical reasons, still continue to use galvanized iron conduit or copper pipe in the existing most of houses of China as running water pipe, and some more outmoded houses have only live wire and zero line especially in the power supply, and there is no earth connection, therefore, when electric heater leaks electricity, electric current can't safe release, thereby make the running water pipe of metal and tap charged, cause user's electric shock accidents.For this reason, my company has designed the electric heater of the water inlet pipe and water outlet pipe joint of cylindrical shell for the insulation material, and with its called after " insulator ", because the pipe joint by the insulation material between electric heater and its external water inlet pipe and water outlet pipe is separated, even therefore electric heater leaks electricity, can not leak outside it yet, thus assurance user's safety.Yet after all, my company has sold a large amount of electric heaters that has metallic pipe coupling before this, and, other manufacturers are still at a large amount of productions electric heater of the same type, and therefore, how making these water heaters benefits load onto " insulator " just becomes a problem demanding prompt solution.A simple design is the joint of an insulation material that directly is threaded on the metallic pipe coupling of original electric heater, one of this insulating joint is an internal thread, be threaded with the metallic pipe coupling on the electric heater, one is external screw thread, be used for being threaded with external water inlet pipe and water outlet pipe, yet, such connection means that insulating joint is screwed onto outside the metallic pipe coupling of electric heater, and because the more nonmetallic insulation material of the effect of expanding with heat and contract with cold of metal is remarkable, therefore, in winter, drainage directly takes place in the metallic pipe coupling of insulating joint and electric heater easily.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of at above-mentioned prior art present situation can make existing water heater have anticreep function, can effectively prevent the anticreeper that leaks between the pipe joint again.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: the anticreeper of this electric heater comprises that metal joint and at least one head that two is internal thread are externally threaded insulating joint, wherein one of metal joint is threaded with insulating joint, the other end is used for being threaded with the admitting pipe joint or the titting water outlet of electric heater, and the other end of insulating joint then is used for being connected with external water pipe.
Certainly, described insulating joint preferably two is external screw thread, is threaded with original external water pipe with convenient.
Compared with prior art, the utility model has been realized anticreep function by set up insulating joint between electric heater and external water pipe, and be the metal joint of internal thread dexterously by two, insulating joint is positioned within the metal joint, therefore, in winter, metallic pipe coupling on the electric heater and the metal joint of setting up shrinkage in the lump, and make the insulating joint that to be positioned at it wrap up tightlyer, thereby thoroughly stop the generation of leaking between the two.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment.
Fig. 2 is the I portion cutaway view Amplified image of Fig. 1.
The specific embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
As shown in Figure 1 and Figure 2, the anticreeper of electric heater 1 comprises that metal joint 2 and two that two is internal thread are externally threaded insulating joint 3, wherein 2 one of metal joints are threaded with insulating joint 3, the other end is threaded with the water-in and water-out pipe joint 11 of electric heater, the other end of insulating joint 3 then is connected with external water pipe 4,12 is the shell of electric heater among the figure, the inner bag cylindrical shell of 13 electric heaters, and 14 is the water pipe in the inner bag cylindrical shell.
Certainly, also can adopt other quick connected mode between described insulating joint 3 and the external water pipe 4, and not adopt thread connecting mode, at this moment, one of 4 need of insulating joint have external screw thread to get final product.
Claims (2)
1, a kind of anticreeper of electric heater, it is characterized in that comprising that metal joint and at least one head that two is internal thread are externally threaded insulating joint, wherein one of metal joint is threaded with insulating joint, the other end is used for being threaded with the admitting pipe joint or the titting water outlet of electric heater, and the other end of insulating joint then is used for being connected with external water pipe.
2, the anticreeper of electric heater according to claim 1 is characterized in that described insulating joint two is external screw thread.
