Goal of the invention of the present utility model is achieved in that a kind of water inlet pipe of electric heater, comprise the oral siphon that is installed on the water tank, wherein, described oral siphon comprise for water flow to logical inlet pipe casting be used for to change feed water flow to the dash end cap, described inlet pipe casting is provided with brace rod, and inlet pipe casting is connected with the dash end cap by brace rod and forms feed water flow to the delivery port of water tank cavity.
Be optimized according to above-mentioned, described dash end cap top has makes the flange that flows to into water downwards.
Be optimized according to above-mentioned, described dash end cap is provided with several attachment fasteners, and the dash end cap is installed on the top of inlet pipe casting by attachment fastener.
Be optimized according to above-mentioned, described attachment fastener is uniformly distributed on the outer rim of the sidewall bottom the dash end cap.
Be optimized according to above-mentioned, described inlet pipe casting is provided with the installation button hole of corresponding attachment fastener, and attachment fastener matches to be installed on and installs on the button hole, makes the dash end cap be fixedly installed in the top of inlet pipe casting.
Be optimized according to above-mentioned, described inlet pipe casting has water entering section and peripheral circumferential section, and the water side of water entering section is connected with peripheral circumferential section bottom and forms cross section " T " font.
Be optimized according to above-mentioned, the corresponding attachment fastener of described installation button hole is arranged on the sidewall of peripheral circumferential section.
Be optimized according to above-mentioned, the water side of described water entering section is connected with peripheral circumferential section sidewall by brace rod.
Rack in the relative prior art of the utility model, its advantage is, inlet pipe casting and dash end cap are by the attachment fastener installation that matches, the current that make inlet pipe casting after running into the stopping of dash end cap to around diffusion and flow out along the wall of dash end cap, change the direction of a stream of water and make it to dirty, simple in structure; And, because the water entering section of inlet pipe casting is connected by brace rod with peripheral circumferential section, guarantee maximum water-outlet area, thereby in the uniform situation of water velocity, reduce to greatest extent and water speed, and do not disturb current, and then the raising hot water delivery rate.
