Problems solved by technology

[0003] There is also a potential safety hazard in the use of this electric water heater
Since electric water heaters usually need to be energized in advance to preheat the water in the water storage tank 1, and the preheating time is relatively long, once the water is cut off during the preheating process, the pressure in the tap water pipe will gradually decrease. When the pressure difference of the pipe reaches the preset value for opening the pressure relief valve, the pressure relief valve will automatically open, and the water body in the water storage liner 1→inner liner water inlet pipe 3→water heater water inlet pipe 5→tap water pipe (not shown in the figure) ) to balance the pressure difference inside and outside the water storage liner 2, but this causes the water level in the water storage liner 1 to decrease, and when the water level is lower than the height of the preheating electric heating tube 2, it will cause the electric water heater to dry
Therefore, existing electric water heaters have relatively large potential safety hazards, and it is necessary to further avoid dry burning caused by water outages on the basis of ensuring the safe use of electric water heaters, effectively improving the safety of electric water heaters and reducing failures in use.

Embodiment 1

[0023] refer to figure 2 , an electric water heater provided with a water inlet diversion pipe, which includes a water storage liner 1, an inlet water diversion pipe, a preheating electric heating pipe 3, an outlet water diversion pipe 5, a cast aluminum electric heater and a constant temperature outlet valve 7 .

[0024] The water storage inner tank 1 has a first inner tank part 13 and a second inner tank part 14 arranged symmetrically from left to right and connected to each other. The bottom ends of the first inner tank part 13 and the second inner tank part 14 are respectively provided with second A mounting base 131 and a second mounting base 141 . The first mounting seat 131 has an inner tank water inlet and an inner tank water inlet joint 11 . The second mounting base 141 has an inner tank water outlet and is provided with an inner tank water outlet joint 12 .

[0025] The preheating electric heating tube 3 is installed in the second liner part 14 of the water stora...

Embodiment 2

[0034] refer to image 3 and Figure 4 , The electric water heater provided with the water inlet guide pipe of this embodiment differs from Embodiment 1 in that: the water inlet guide pipe in this embodiment is a double-layer guide pipe 4 .

[0035] The double-layer guide tube 4 has an inner tube part 41 and an outer tube part 42 . The outer pipe part 42 is a tubular structure with an end plate 421 at one end and a closed end at the other end. The middle part of the end plate 421 has a socket hole, and the side wall near the end plate 421 of the outer pipe part 42 has a plurality of water supply ports 23 with a hole-shaped structure. 1. There is an exhaust hole 24 on the side wall near the closed end. The inner tube part 41 is a tubular structure with a connection port 411 at one end and a communication port 412 at the other end. The inner tube part 41 is coaxially inserted into the outer tube part 42 through the sleeve hole of the outer tube part 42, and its connection port...
