[0024] The present invention will be further described below with reference to the accompanying drawings:

[0025] A water inlet pipe assembly for an electric water heater includes a base 1 having a base hole 2 formed therein. A water conduit 3 is provided at one end of the base 1, one end of the water conduit 3 communicating with the base hole 2 and the other end of the water conduit 3 being sealed. The water conduit 3 is provided with a plurality of water outlet holes 4, each of which is peripherally provided with a flow stabilizer 5 extending in the direction of water inlet. The flow stabilizer 5 of the present invention effectively slows and stabilizes the water flow rate, overcoming the drawback of the prior art of rapid water outlet speeds that damage the water layer in the inner tank, thereby improving the hot water outlet rate.

[0026] The flow stabilizer 5 of the present invention comprises a connecting portion 6 connected to the water conduit 3, and a flow stabilizer 7 connected to the connecting portion 6 and extending in the direction of water inflow from the water conduit. The connecting portion 6 is a horizontal plate, and the flow stabilizer 7 is a vertical plate. The connecting portion 6 and the flow stabilizer 7 are perpendicularly connected. The surface of the flow stabilizer 7 closest to the water outlet, i.e., the inner surface, is flat, while the outer surface, i.e., the other surface, can be curved, flat, or irregular.

[0027] The present invention can be a pair of water outlet holes symmetrically arranged on the water guide pipe to form a water discharge hole. The water guide pipe 3 is provided with multiple water discharge holes, and a pair of flow stabilizing plates 5 are provided on the periphery of each pair of water discharge holes. The spacing between each water discharge hole is preferably the same. Water enters the water guide pipe 3 from the base hole 2 of the base 1 and then flows out of the water outlet hole 4. After flowing out of the water outlet hole 4, it is blocked by the flow stabilizing plates 5, and most of the water flows back to the water inlet direction of the water guide pipe, forming a backflow, effectively slowing down and stabilizing the water flow rate, overcoming the defects of the prior art of rapid water discharge and damage to the water layer in the inner tank, and improving the hot water output rate.

[0028] The two water outlet holes 4 in each row of water outlet holes of the present invention are both circular holes, and the center lines of the circles of the two water outlet holes 4 are on the same straight line.

[0029] The water conduit 3 of the present invention has a groove 31 located at the outlet 4, and a flow stabilizer 5 is disposed around the periphery of the groove 31. The groove 31 has an arcuate cross-section, with the lower and upper outer edges of the groove 31 forming a horizontal plane. The upper surface of the groove 31 is flush with the lower surface of the connecting portion 6.

[0030] The width of the flow stabilizing plate 5 of the present invention is greater than or equal to the width of the groove 31 , and is preferably the width of the flow stabilizing plate 5 .

[0031] The base 1, the water conduit 3 and the flow stabilizing plate 5 of the present invention are an integrated structure, and the base 1, the water conduit 3 and the flow stabilizing plate 5 are integrally formed by using materials such as plastic and metal.
