Water inlet pipe assembly and water tank

The utility model discloses a water inlet pipe assembly and a water tank, and belongs to the technical field of water storage type water heater. The water inlet pipe assembly comprises a water inlet pipe, a flow guide cover and a flow shielding cover. The upper portion of the water inlet pipe is sleeved with the flow guide cover, the flow shielding cover is arranged above the water inlet pipe in a covering mode, a flow guide space with the closed upper end is formed between the flow guide cover and the flow shielding cover, a lower end outlet of the flow guide space extends outwards in the horizontal direction, the cross section area of the flow guide space is larger than that of a water outlet, cold water enters the flow guide space through the water inlet pipe, and the flow guide space reduces the flow rate of the cold water and changes the direction of water flow, so that the cold water flowing out of the flow guide space forms steady flow in the horizontal direction; by means of the water inlet pipe assembly, the cold water is prevented from disturbing the water flow to the greatest extent, cold water and hot water mixing is reduced, and the hot water output rate of the water tank is increased.
