[0038] like Figure 1-Figure 3 As shown, this embodiment provides an electric water heater, including a shell assembly 1 and an inner tank 2. The shell assembly 1 includes an outer shell, a support member 15, an upper end cover 16 and a lower end cover 17. The outer shell is arranged to pass through from top to bottom. The upper end cover 16 is provided at the upper end of the outer shell, and the lower end cover 17 is connected to the lower end of the outer shell. The upper end cover 16 and the lower end cover 17 are fixed to the outer shell by snapping. The inner tank 2 is provided in the shell assembly 1, and the inner tank 2 is placed horizontally in the outer shell. Two support members 15 are provided, and the two support members 15 are connected to the inner sides of the two side panels 13 in a one-to-one correspondence to increase the strength of the outer shell.

[0039] The housing includes a front panel 11 and a back panel 12, which are positioned opposite each other, and two side panels 13, which are positioned opposite each other. Both the front panel 11 and the back panel 12 are connected to the side panels 13 via curved connecting plates 14. The side panels 13 are connected to the front panel 11 and the back panel 12 via the curved connecting plates 14. An opening 131 is provided on one of the side panels 13, which improves the housing's resistance to deformation and increases its overall strength. This effectively reduces the likelihood of deformation and dents during foaming, thereby improving the quality and aesthetics of the electric water heater.

[0040] In one embodiment, the housing is integrally formed by injection molding, which further increases the anti-deformation capability and ensures the overall strength of the housing.

[0041] In one embodiment, one of the support member 15 and the side panel 13 is provided with a snap-fitting hole 132, and the other is provided with a snap-fitting member 152. The snap-fitting member 152 cooperates with the snap-fitting hole 132 to snap-fit the support member 15 to the side panel 13. The snap-fitting fixation between the support member 15 and the side panel 13 facilitates the connection between the support member 15 and the side panel 13. Compared to screw fixing, there is no need to drill holes in the side panel 13, further preventing the strength of the housing from being affected by the drilling holes.

[0042] Illustratively, a plurality of snap-fitting members 152 are provided at circumferential intervals on the support member 15 , and a plurality of snap-fitting holes 132 are correspondingly provided on the side plate 13 . The snap-fitting members 152 can be buckles or protrusions that match the snap-fitting holes 132 .

[0043] The support member 15 connected to the outside through the opening 131 is also provided with an avoidance hole 153 for avoiding the end of the inner pot 2. In this embodiment, there are two inner pots 2 along the upper and lower directions of the shell. Accordingly, two avoidance holes 153 are provided on the support member 15.

[0044] In one embodiment, one of the support members 15 is connected to the outside through an opening 131. Two connecting pipes 151 are provided on the support member 15 connected to the outside through the opening 131. The connecting pipes 151 are used to connect the inside and outside of the shell; one of the connecting pipes 151 is used for foaming; the other connecting pipe 151 is used for exhausting. On the side panel 13 having the opening 131, multiple snap-in holes 132 are located circumferentially around the opening 131, allowing the support member 15 to connect to the outside of the shell. The two connecting pipes 151 are provided between two avoidance holes 153. By providing two connecting pipes 151 on the side panel 13 connected to the outside, one of the connecting pipes 151 is used for injecting foaming material and the other is used for exhausting, uniform foaming filling is ensured while reducing the pressure exerted by the foaming material on the shell. At the same time, the injection and exhaust of the foaming material are separated and do not affect each other, making the injection of the foaming material smoother and ensuring uniform foaming filling between the shell and the inner liner 2.

[0045] In one embodiment, a first cushion block 4 is provided between the inner liner 2 and the back plate 12. The first cushion block 4 is positioned between the inner liner 2 and the back plate 12 to ensure that there is sufficient foaming space between the inner liner 2 and the back plate 12, thereby preventing the side plate 13 from being deformed by the pressure of the foaming material.

[0046] In one embodiment, if Figure 1 and Figure 2As shown, a second pad 154 is further provided on the side of the support member 15 close to the inner liner 2. A plurality of second pads 154 are arranged at circumferential intervals along the support member 15. The second pads 154 are located between the inner liner 2 and the support member 15 to ensure that there is sufficient foaming space between the inner liner 2 and the side panel 13 to prevent the side panel 13 from being deformed due to the pressure of the foaming material.

[0047] Of course, in order to prevent the panel 11 from being deformed due to the pressure of the foaming material, sufficient foaming space must be left between the panel 11 and the inner container 2.

[0048] like Figure 1 and Figure 3 As shown, the housing assembly 1 also includes two external panels 5, and the two inner tanks 2 are connected by two connecting plates 7. The external panels 5, first spacers 4, and connecting plates 7 are correspondingly arranged. The external panels 5 are fixed to the wall on which the electric water heater is mounted. External screws 6 pass through the external panels 5, first spacers 4, and connecting plates 7 to connect them, allowing the external panels 5 to bear the weight of the inner tanks 2. Furthermore, two first spacers 4 are arranged between each external panel 5 and its corresponding connecting plate 7 to ensure the stability of the electric water heater.

[0049] In one embodiment, continue to refer to Figure 1 and Figure 2 A buffer member 3 is provided between the lower end cap 17 and the inner liner 2. The side of the buffer member 3 closest to the inner liner 2 is provided with an arcuate positioning surface 31 that mates with the outer periphery of the inner liner 2. The buffer member 3 can be made of a material such as foam or rubber pad. The buffer member 3 is tightly pressed between the lower end cap 17 and the inner liner 2, and the arcuate positioning surface 31 increases the contact area between the inner liner 2 and the buffer member 3, ensuring the stability of the inner liner 2 within the outer shell.

[0050] In one embodiment, the bottom of the inner container 2 is provided with an inlet and outlet pipe 21. The buffer member 3 is provided with a first positioning hole 32 for the inlet and outlet pipe 21 to pass through, and the lower end cover 17 is provided with a second positioning hole 171 for the inlet and outlet pipe 21 to pass through. The inlet and outlet pipes 21 of the inner container 2 pass through the first positioning hole 32 and the second positioning hole 171, respectively, to connect to external tap water or a water dispenser. During installation, the buffer member 3 is positioned using the first positioning hole 32, and then the lower end cover 17 is pressed into the buffer member 3 and connected to the outer shell. The second positioning hole 171 serves to position the lower end cover 17.

[0051] The inlet and outlet water pipes 21 include a cold water inlet pipe 211, a hot water outlet pipe 212 and a cold water return pipe 213. Accordingly, three first positioning holes 32 and three second positioning holes 171 are provided to allow the cold water inlet pipe 211, the hot water outlet pipe 212 and the cold water return pipe 213 to pass through respectively.

[0052] In one embodiment, the electric water heater also includes a display screen. The housing assembly 1 also includes a mounting base 18. The panel 11 is provided with a mounting opening 111. The mounting base 18 is connected to the mounting opening 111 to secure the display screen.

By attaching the mounting base 18 to the mounting opening 111, the display screen is secured, making it convenient for users to view or adjust the hot water temperature through the display screen.

[0053] In one embodiment, if Figure 1 and Figure 3 As shown, the mounting base 18 includes a base 181 and a mounting base body 182. The base 181 is disposed on the inner side of the panel 11, and the mounting base body 182 is disposed on the outer side of the panel 11. The mounting base body 182 is provided with a hook 1821. The hook 1821 extends into the inner side of the panel 11 through the mounting opening 111 and cooperates with the base 181 to clamp and secure the mounting base 18 to the panel 11, and the display screen is secured to the mounting base body 182. By providing the base 181 and the mounting base body 182, the mounting base 18 is clamped and secured to the panel 11, with minimal impact on the strength of the panel 11.

[0054] Specifically, the base 181 includes an abutting end plate and a first cylinder wall, the abutting end plate is arranged in the circumference of one end of the first cylinder wall, and is used to abut against the inner wall of the panel 11, the mounting seat body 182 includes a circular buckle plate and a second cylinder wall, the circular buckle plate is arranged in the circumference of one end of the second cylinder wall, the circular buckle plate is used to buckle with the outer wall of the panel 11, the hook 1821 is provided at the end of the second cylinder wall away from the circular buckle plate, during installation, after the second cylinder wall is inserted into the first cylinder wall, the hook 1821 can hook the end face of the first cylinder wall away from the abutting end plate, so that the abutting end plate abuts against the inner wall of the panel 11, and the circular buckle plate is buckled to the outer wall of the panel 11, thereby realizing the clamping and fixation of the mounting seat 18 and reducing the impact on the strength of the panel 11.

[0055] A plurality of hooks 1821 are arranged at intervals along the circumferential direction of the second cylinder wall. The plurality of hooks 1821 simultaneously hook the end surface of the first cylinder wall away from the end plate, thereby ensuring the stability of the clamping of the mounting seat 18 .

[0056] In one embodiment, if Figure 4 and Figure 5 As shown, a positioning notch 1111 is provided on one side of the mounting opening 111, and a positioning protrusion 1811 is provided on the base 181. The positioning protrusion 1811 cooperates with the positioning notch 1111 to position the base 181. The positioning protrusion 1811 is provided on the abutting end plate. When installing the base 181, the positioning protrusion 1811 is first engaged with the positioning notch 1111, and then the second tube wall is inserted into the first tube wall. This ensures the accuracy of the connection position between the mounting base body 182 and the base 181, making installation more convenient.

[0057] The electric water heater provided in this embodiment is constructed with a vertically continuous outer shell. After connecting support members 15 to both sides of the side panels 13, the inner shell 2 is placed horizontally within the outer shell. During installation, the external mounting plate 5 is first secured to the mounting wall. The inner shell 2 and the outer shell are then secured to the mounting wall using external mounting screws 6 that pass through the external mounting plate 5, the first spacer 4, and the connecting plate 7. The mounting base 18 is then clamped and secured to the panel 11, and the display is mounted on the mounting base 18. After the buffer member 3 is aligned with the inlet and outlet pipes 21 of the inner shell 2 through the first positioning perforation 32, the second positioning perforation 171 of the lower end cap 17 is passed through the inlet and outlet pipes 21, and the buffer member 3 is pressed and secured to the outer shell. The upper end cap 16 is then snapped onto the upper end of the outer shell. Finally, foam material is injected into the outer shell through one of the connecting pipes 151. During the injection process, the foam material is exhausted through the other connecting pipe 151, ensuring that the outer shell does not deform or dent, thereby improving the quality and aesthetics of the electric water heater.
