[0025] like Figure 1-Figure 4 As shown, an assembly structure of a household appliance is provided, including a base 1, a shell 2 and a top cover 3, a connecting structure 4 is provided between the base 1 and the top cover 3, the connecting structure 4 includes a supporting column 401 and a connecting column 402, the supporting column 401 is arranged on the base 1, and the connecting column 402 is arranged on the top cover 3, when the top cover 3 is installed on the base 1, the connecting column 402 is overlapped on the supporting column 401, and the screw passes through the supporting column 401 and is fastened to the connecting column 402.

[0026] Specifically, by using the overlapping structure of the support column 401 and the connecting column 402 between the top cover 3 and the base 1, and fixing with screws, fast and reliable assembly can be achieved. This structure simplifies the assembly process and improves production efficiency.

[0027] Furthermore, the household appliance includes an electric heater or a water pump, and the electric heater and the water pump can be assembled using the above-mentioned assembly structure.

[0028] Further, if Figure 1 and Figure 4 As shown, the top cover 3 is provided with a surrounding edge 301 extending downward, and heat dissipation holes 3011 are arranged around the surrounding edge 301 .

[0029] Specifically, the heat dissipation holes 3011 are designed on the downward extending surrounding edge 301 of the top cover 3, which can effectively utilize the principle of thermal convection to promote the hot air to rise and be released from the top, thereby improving the heat dissipation efficiency, while also avoiding the impact of the side heat dissipation holes on the product appearance.

[0030] Further, if Figure 1 As shown, a convex rib 302 is provided on the top cover 3, and a spacing distance a is provided between the top cover 3 and the outer shell 2 through the convex rib 302, and the heat dissipation hole 3011 is connected to the outside through the spacing distance a.

[0031] Specifically, by providing the ribs 302 on the top cover 3 and maintaining a certain spacing distance a between the top cover 3 and the outer shell 2, the space for air flow can be effectively increased, thereby promoting the rise of hot air and the circulation of cold air, and improving the overall heat dissipation performance.

[0032] Further, if Figure 3 and Figure 4 As shown, the base 1 is provided with an extending edge 101 extending upward, and when the housing 2 is installed on the base 1 , the housing 2 surrounds the extending edge 101 .

[0033] Specifically, the extended edge 101 enhances the structural stability of the entire device and provides a convenient positioning and fixing method for the installation of the housing 2 .

[0034] Further, if Figure 1 , Figure 3-Figure 5 As shown, the base 1 is provided with a stepped groove 102 , and the shell 2 is provided with a groove 201 corresponding to the stepped groove 102 . When the shell 2 is installed on the base 1 , the groove 201 is matched and connected with the stepped groove 102 , so that the bottom of the shell 2 is in the same horizontal plane as the base 1 .

[0035] Specifically, through the precise matching of the stepped groove 102 on the base 1 and the groove 201 of the shell 2, more precise alignment and fixation can be achieved, thereby enhancing the structural stability of the entire shell 2 and the base 1.

[0036] Further, if Figure 2 and Figure 3 As shown, a slot 4011 is provided on the support column 401 , and the connecting column 402 is overlapped on the slot 4011 .

[0037] Specifically, the slot 4011 provides a specific fixing point on the support column 401, so that the connecting column 402 can be accurately overlapped and locked in place. This matching method not only ensures the accuracy of assembly, but also increases the convenience of disassembly and assembly.

[0038] Furthermore, the housing 2 is at least made of wood, metal, or plastic.

[0039] Further, if Figure 4 As shown, a first reinforcing rib 5 is provided between the connecting column 402 and the surrounding edge 301 .

[0040] Specifically, the provision of the first reinforcing rib 5 can effectively enhance the connection strength between the connecting column 402 and the surrounding edge 301 , thereby improving the structural stability of the entire top cover 3 .

[0041] Further, if Figure 3 As shown, a second reinforcing rib 6 is provided between the support column 401 and the extension edge 101 .

[0042] Specifically, the provision of the second reinforcing rib 6 can effectively enhance the connection strength between the support column 401 and the extension edge 101 , thereby improving the structural stability of the entire base 1 .

[0043] Further, if Figure 1 and Figure 4 As shown, a supporting foot 103 is provided at the bottom of the base 1 , and the supporting foot 103 is arranged corresponding to the supporting column 401 .

[0044] Specifically, the support feet 103 can effectively increase the grounding area of ​​the electric heater and provide better stability, especially when used on uneven or smooth surfaces. Such a design helps prevent the device from tipping over and ensures safety during use.

[0045] Specifically, the heat dissipation holes 3011 are in the shape of long strip openings or circular openings arranged in an array.
