The present embodiment provides a thermal storage type water heater, as shown in fig. 1 and 2, which includes a liner 100, a water inlet pipe 200, and a water outlet pipe 300. A water storage cavity for storing water is formed on an inner wall surface of the inner container 100, and the water stored in the inner container 100 can be heated to a certain temperature by a heating element provided in the inner container 100. The bottom of the inner container 100 is provided with a first mounting hole and a second mounting hole, the first mounting hole is used for mounting the water inlet pipe 200, and the second mounting hole is used for mounting the water outlet pipe 300.

The water inlet pipe 200 is used to communicate the water storage cavity inside the inner container 100 with an external water source, so that cold water with a low external temperature can flow into the water storage cavity of the inner container 100 through the water inlet pipe 200. In the present embodiment, the water inlet pipe 200 includes a first pipe 210 and a second pipe 220 connected to each other. The first pipe 210 is inserted into the first installation hole, one end of the first pipe 210 is located outside the inner container 100, and the end of the first pipe 210 is used for being directly connected with a water source or being connected with the water source through a hose, and the other end of the first pipe 210 is located in the water storage cavity of the inner container 100. The second pipe 220 is communicated with one end of the first pipe 210 located in the inner container 100, and the second pipe 220 is horizontally disposed at the bottom of the inner container 100, as shown in fig. 3 to 5, a plurality of water outlet holes 201 are disposed on the second pipe 220 along the axial direction, so that the water inlet pipe 200 can inject cold water into the inner container 100 at the bottom of the inner container 100.

In the present embodiment, the shape of the longitudinal section of the second tube 220 is a polygon, such as a quadrangle, a pentagon, or a polygon having a larger number of sides, i.e., the second tube 220 is a polygonal tube. Compared with the prior water heater, the water inlet pipe of the water heater adopts a round pipe, and the wet circumference of the polygonal pipe is larger, so that the flow speed of cold water flowing through the polygonal pipe can be effectively reduced, the kinetic energy of the cold water can be reduced, and the cold water can be ensured to slowly flow into the inner container 100 with the minimum kinetic energy. And because the second pipe 220 is set up in the bottom of the inner bag 100 horizontally, can realize the axial wide range of inner bag 100 is intake, reduce the kinetic energy of cold water, can make cold water flow into the bottom of the inner bag 100 more evenly, and the cold water that gets into in the inner bag 100 by the second pipe 220 is far away with the hot water distance that is located the top of the inner bag 100, the mixing speed is slower, thereby can reduce the influence of the cold water that gets into in the inner bag 100 from the second pipe 220 to the hot water temperature that is located the top of the inner bag 100 and prepares to export from the inner bag 100, make the temperature equilibrium of the water that flows out from the inner bag 100 better, help to improve the hot water output rate and improve user's use and experience, avoid the appearance of the high and sudden low phenomenon of temperature when the user uses water.

In some specific embodiments, the second tube 220 has a quadrilateral longitudinal cross-section. In some more particular embodiments, the second tube 220 is square in longitudinal cross-section.

With continued reference to fig. 4 and 5, the first pipe 210 and the second pipe 220 are vertically connected, that is, the first pipe 210 is vertically inserted into the first installation hole. The shape of the first tube 210 is adapted to the shape of the first mounting hole, in some embodiments, the first mounting hole is a circular hole, and the first tube 210 is a circular tube; in some other embodiments, the first mounting hole is a polygonal hole and the first tube 210 is a polygonal tube, i.e., the cross-sectional shape of the first tube 210 is a polygon. Compared with a round tube, the first tube 210 is a polygonal tube, the wetted perimeter of the first tube 210 can be increased, so that cold water can be subjected to primary speed reduction in the first tube 210, secondary speed reduction can be performed after the cold water enters the second tube 220, the water speed can be reduced more quickly due to the two-stage speed reduction, and the cold water can slowly enter the bottom of the inner container 100 at a lower speed.

When cold water flows into the second pipe 220 from the first pipe 210, the cold water is divided, wherein a part of the cold water flows into the left side pipe, and the rest of the cold water flows into the right side pipe, and the water flow speed can be reduced in the dividing process.

In some embodiments, the first tube 210 and the second tube 220 can be connected in an L-shape, so that the first tube 210 can be mounted to one end of the liner 100 for tube arrangement.
