[0022] The following will be combined with the drawings of the specification of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] Reference Figure 1-Figure 3 The utility model provides an embodiment: a detachable and washable electric water heater shell 2, comprising a shell 2, a front shell 1 being rotatably connected to the front side of the shell 2, an inner tank 4 being provided on the inner wall of the shell 2, a water inlet pipe 9 being fixedly connected to the bottom of the shell 2, a first groove 11 beginning to be provided on the outer surface of the water inlet pipe 9, a connecting frame 10 being provided on the outer surface of the water inlet pipe 9, a rotating nozzle 15 being provided on the top of the connecting frame 10, a second connecting piece 13 being fixedly connected to the bottom of the inner wall of the connecting frame 10, a second silicone ring 16 being fixedly connected to the bottom of the rotating nozzle 15, a second silicone ring 16 being fixedly connected to the top of the inner wall of the water inlet pipe 9, a connecting pipe 22 being fixedly connected to the bottom of the inner tank 4, and a quick-release assembly being provided on the right side of the inner tank 4, which is used for convenient disassembly of the heating rod 6.

[0024] Specifically, by arranging a water inlet pipe 9 at the bottom of the inner tank 4 and a rotating nozzle 15 at the top of the water inlet pipe 9, when the inner tank 4 needs to be cleaned, the rotating nozzle 15 can spray a high-pressure water column to clean the inner tank 4 360 degrees. When the water heater is in normal use, the rotating nozzle 15 is higher than the water inlet pipe 9 and does not affect the use of water inlet. When cleaning is needed, the front shell 1 is opened to expose the water inlet pipe 9 and the bottom of the connecting frame 10. The connecting frame 10 and the water inlet pipe 9 are connected by a first connecting member 12, so that the connecting frame 10 can slide up and down on the outer surface of the water inlet pipe 9. The rotating nozzle 15 is inserted into the top of the water inlet pipe 9 and passes through the first silicone ring 14 which is thin on the top and thick on the bottom. A second silicone ring 16 is also provided between the rotating nozzle 15 and the water inlet pipe 9, so that the rotating nozzle 15 and the water inlet pipe 9 fit tightly, solving the problem that it is too troublesome to completely remove the inner tank 4 for cleaning when cleaning the inner tank 4 of the electric water heater.

[0025] Reference Figure 4The quick-release assembly includes a heating controller 5, which is threadedly connected to the left side of the heating controller 5 and the right side of the inner tank 4. A heating rod 6 is fixedly connected to the left side of the heating controller 5. Evenly distributed second grooves 17 are opened on the right side of the inner tank 4. Evenly distributed fixing parts 19 are provided on the right side of the heating controller 5. The fixing parts 19 pass through and extend to the left side of the heating controller 5. A wire 21 is fixedly connected to the right side of the heating controller 5.

[0026] Specifically, a heating controller 5 and a heating rod 6 are arranged on the right side of the inner tank 4 to heat the water in the inner tank 4. The heating controller 5 is threadedly connected to the right side of the inner tank 4, and the heating controller 5 and the inner tank 4 are connected by a fixing part 19. When disassembling, press the fixing part 19 to rotate, remove the fixing part 19, rotate the heating controller 5 to remove the heating rod 6, and solve the problem of troublesome disassembly when replacing the heating rod 6 in the electric water heater.

[0027] Reference Figure 4 The right side of the outer surface of the inner tank 4 is threadedly connected with a protective shell 18.

[0028] Specifically, when the water heater is normally used, the protective shell 18 is connected to the right side of the inner tank 4 to cover the heating controller 5 to prevent it from being wetted by water.

[0029] Reference Figure 3 , the outer surface of the connecting frame 10 and the connecting pipe 22 are tightly fitted.

[0030] Specifically, the connecting frame 10 and the connecting pipe 22 fit tightly together and can slide up and down.

[0031] Reference Figure 4 , the left side of the fixing member 19 is tightly fitted with the second groove 17.

[0032] Specifically, the fixing part 19 passes through the heating controller 5 and is connected by a spring 20. After the heating controller 5 and the inner pot 4 are threadedly connected, the fixing part 19 is pressed to be inserted into the second groove 17, and then the fixing part 19 is rotated so that the fixing part 19 is tightly fastened to the inner pot 4 under the tension of the spring 20.

[0033] Reference Figure 2 The outer shell 2 and the inner shell 4 are directly fixedly connected with the insulation layer 3.

[0034] Specifically, a heat-insulating layer 3 is provided on the outer wall of the inner tank 4 so that the hot water in the water heater is kept warm after being heated.

[0035] Reference Figure 2 A sewage pipe 8 is fixedly connected to the bottom of the shell 2, and the sewage pipe 8 passes through the shell 2, the insulation layer 3 and the inner liner 4 in sequence.

[0036] Specifically, the top of the drain pipe 8 is set at the bottom of the inner wall of the inner tank 4, and the water sprayed for cleaning and the scale cleaned flow out through the drain pipe 8.

[0037] Reference Figure 2 A hot water outlet 7 is fixedly connected to the bottom of the shell 2, and the hot water outlet 7 passes through the shell 2, the insulation layer 3 and the inner tank 4 in sequence.

[0038] Specifically, after being heated, water will be lighter than cold water and will float upwards. The top of the hot water outlet 7 is at the top of the inner tank 4, so that hot water flows out.

[0039] Working principle: by setting the water inlet pipe 9 at the bottom of the inner tank 4 and setting the rotating nozzle 15 at the top of the water inlet pipe 9, when the inner tank 4 needs to be cleaned, the rotating nozzle 15 can spray a high-pressure water column to clean the inner tank 4 360 degrees. When the water heater is in normal use, the rotating nozzle 15 is higher than the water inlet pipe 9 and does not affect the use of water. When cleaning is needed, the front shell 1 is opened to expose the water inlet pipe 9 and the bottom of the connecting frame 10. The connecting frame 10 and the water inlet pipe 9 are connected by the first connecting piece 12, so that the connecting frame 10 can slide up and down on the outer surface of the water inlet pipe 9. The rotating nozzle 15 is inserted into the top of the water inlet pipe 9, passes through the first silicone ring 14 which is thin at the top and thick at the bottom, and rotates. A second silicone ring 16 is also provided between the nozzle 15 and the water inlet pipe 9, so that the rotating nozzle 15 fits tightly against the water inlet pipe 9, solving the problem that it is too troublesome to completely remove the inner tank 4 for cleaning the inner tank 4 of the electric water heater. A heating controller 5 and a heating rod 6 are provided on the right side of the inner tank 4 to heat the water in the inner tank 4. The heating controller 5 is threadedly connected to the right side of the inner tank 4, and the heating controller 5 and the inner tank 4 are connected by a fixing part 19. When disassembling, press the fixing part 19 to rotate, remove the fixing part 19, rotate the heating controller 5 to remove the heating rod 6, and solve the problem of troublesome disassembly when replacing the heating rod 6 of the electric water heater.
