[0020] Therefore, the beneficial effects of this utility model are:

[0021] 1. By using a side-biased layout for the heating element, an adjustment area is added. This area allows the inlet pipe to swing laterally to adjust the distance between the other ends of the inlet and outlet pipes. This increases the lateral adjustment function of the inlet pipe installation position. Therefore, when facing installation situations where the distance between the two pipe interfaces on the wall varies in different countries and regions, the water heater can be installed in a suitable position on the wall, and after connecting the other end of the outlet pipe to one pipe interface, the other end of the inlet pipe can be laterally swung to a suitable position to connect the other pipe interface. This improves the adaptability of the water heater installation, eliminates the need for external extension pipes, increases installation efficiency, reduces installation costs, and avoids adding pipe connection points, reducing the risk of leakage and improving the user experience.

[0022] 2. The length adjustment function of the inlet and outlet connectors has been added. When connecting two pipe interfaces on the wall of different countries and regions through the inlet and outlet connectors, the length of the inlet and outlet connectors can be adjusted by adjusting the threaded connection depth between the adjusting part and the fixing part. Then, the connecting part is sealed and screwed onto the corresponding pipe interface, thereby completing the adaptive connection of the inlet and outlet connectors, further improving the adaptability, convenience and efficiency of water heater installation.

[0023] 3. The design allows the inlet pipe, except for the connecting part, to swing left and right with its upper end as a fulcrum, enabling the inlet connector to move significantly left and right. This allows the inlet and outlet connectors to be adapted to connect to the two pipe interfaces on the walls of different countries and regions. At the same time, by extending the heating device, control mechanism, and adjustment area vertically and distributing them side by side in the horizontal direction, the compactness of the internal structure of the casing is improved. While adding a control mechanism to improve the intelligent control of the water heater, the design avoids any structure within the adjustment area that would obstruct the horizontal swing of the inlet pipe, thus improving the practicality and flexibility of the horizontal adjustment of the inlet pipe.

[0024] 4. By setting up the detection tube, the flow sensor and pressure switch are centrally installed and fixed, eliminating the need to add more fixing brackets to install and fix the three separately. This can greatly save the installation space of the control device, further improve the structural compactness of the water heater, and the right-side setting of the motor can properly balance the off-center load caused by the left-side offset layout of the heating device, thus improving the stability of the water heater after it is installed on the wall.

[0025] 5. The rear shell can be installed on the wall first, and the water outlet connector and one pipe interface can be connected. After adjusting the water inlet connector to connect to the other pipe interface, the lower shell and the front shell can be installed in sequence. This avoids the front shell and the lower shell from obstructing the connection of the water inlet and outlet connectors when installing the water heater, making it easier to adjust and connect the water inlet connector. This improves the convenience and practicality of water heater installation. On this basis, by adding a limit bracket, the lower end of the water inlet pipe can be offset forward to avoid the obstruction of the motor, so that the adjustment range of the left and right swing of the water inlet pipe can be guaranteed, and the stability of the left and right swing adjustment of the water inlet pipe can be improved.

[0026] 6. The design of several clamping parts improves the ease of sliding connection between the lower and rear housings. The sliding connection between the connector and the sliding groove, in conjunction with the clamping parts, achieves a multi-layered clamping connection between the lower and rear housings, enhancing the stability of the connection. Based on this, the connection between the lower and rear housings is already relatively stable and has left and right limit positions as well as front and rear limit positions. Therefore, the connection between the lower and rear housings can be further secured by screwing in the connecting lugs and connecting holes on both sides. This reduces the number of screwing points between the lower and rear housings, improving the ease of disassembly and assembly, and consequently enhancing the convenience of water heater disassembly, assembly, and pipe maintenance.

[0027] 7. Depending on the height of the cable exiting the wall during actual installation, the terminal block can be moved directly to the upper or lower mounting section for fixing and installation. The corresponding cable interface can be selected to connect the cable inside the wall, facilitating cable and terminal block connection. During this process, there is no need to adjust the internal wiring of the water heater, realizing the adaptation and adjustment function of the water heater circuit incoming line height, further improving the adaptability of water heater installation.

[0028] 8. By adding several fixing holes, the water heater can be installed by selecting two corresponding fixing holes according to the spacing and height of the mounting screw holes on the wall. After fixing the mounting back plate, the housing is then installed onto the mounting back plate, completing the installation and fixing of the water heater on the wall. This improves the adaptability of water heater installation and fixation, and minimizes the difficulty of water heater installation. Attached Figure Description

One end of the connecting part 323 is sleeved in the other end of the adjusting part 322 and is limited by the limiting part 324 and cannot be separated from the adjusting part 322. The above structure increases the length adjustment function of the water inlet joint 32 and the water outlet joint 41. When connecting the two pipe interfaces on the wall in different countries and regions through the water outlet joint 41 and the water inlet joint 32, the threaded depth between the adjusting part 322 and the fixed part 321 can be adjusted to adjust the water outlet joint 41 and the water inlet joint 32 to the appropriate length, and then the connecting part 323 is sealingly and threadedly sleeved on the corresponding pipe interface, so as to complete the adaptive connection of the water inlet joint 32 and the water outlet joint 41, and further improve the installation adaptability, convenience and efficiency of the water heater.
