[0004] Therefore, the structure of the power supply box in the prior art has room for further improvement. Utility Model Content

[0005] In view of this, and considering the technical problems of existing power box installation and disassembly requiring numerous components, complex and inconvenient installation, and increased costs and assembly processes, this application provides a power box installation structure and a dishwasher. By changing the structure of the power box, the installation and disassembly of the power box becomes more convenient, saving assembly time and assembly processes, saving costs and time, and further improving work efficiency.

[0006] To achieve the above objectives, this application provides the following technical solution: a power supply box mounting structure, comprising:

[0007] A power box is installed inside a base. The base has a snap-fit ​​component on the side facing the power box. The power box has a guide groove. The snap-fit ​​component is correspondingly set and cooperates with the guide groove to achieve guiding and positioning of the base and the power box.

[0008] At least one bolt is used to fix the power box to the base, and the assembly direction of the bolt is perpendicular to the assembly direction of the snap-fit ​​component.

[0009] Compared with existing technologies, the power box mounting structure of this application achieves guiding and positioning of the base and the power box by setting up snap-fit ​​components and guide grooves. The snap-fit ​​components also serve a guiding and positioning function, enabling faster and more convenient installation of the power box to the base, thus improving work efficiency. Specifically, at least one bolt connects the power box and the base, with the bolt's assembly direction perpendicular to the snap-fit ​​component's assembly direction. When the bolt is removed, the power box can be easily lifted for disassembly or replacement, resulting in good stability of the power box. Furthermore, it eliminates the need for other fixing structures, saving assembly time and steps, reducing costs and time, and further improving work efficiency.

[0010] Preferably, the lower part of the guide groove is provided with an annular protrusion, which is a radial protrusion and is used to limit or support the snap-fit ​​component.

[0011] In this embodiment, the annular protrusion can prevent the power box from shifting, misaligning, or moving during installation. At the same time, the annular protrusion also limits the locking component to accurately position the power box.

[0012] Preferably, the power box is further provided with at least one hanging member on the side facing the base, and the bottom of the hanging member cooperates with the top of the base to realize the connection between the power box and the base.

[0013] In this embodiment, by setting up a mounting bracket, the connection strength between the power supply box and the base can be improved, preventing loosening or detachment. It also allows the power supply box to be easily mounted on the base, facilitating quick installation and disassembly, as well as subsequent inspection and maintenance, thus improving work efficiency.

[0014] Preferably, the diameter of the upper opening of the guide groove is larger than the diameter of the lower opening.

[0015] In this embodiment, a larger upper groove diameter is used to facilitate mold demolding during injection molding, reduce molding difficulty, lower production costs and time consumption, and improve production efficiency.

[0016] Preferably, the guide groove is recessed towards the center of the power supply box, and the guide groove is an arc-shaped groove.

[0017] In this embodiment, the arc-shaped groove can reduce resistance and friction during the installation of the power supply box, thereby improving the convenience and efficiency of installation.

[0018] Preferably, the power supply box includes a front shell and a rear shell that are fastened together, and a power board is fixed in the space formed by the front shell and the rear shell.

[0019] The guide groove is located on the side of the rear shell away from the front shell, and the guide groove is eccentrically positioned.

[0020] In this embodiment, the guide groove is offset from the center of the rear shell and is far away from the bolt. The eccentric setting makes the guide groove far away from the bolt, which can avoid stress concentration near the bolt hole, reduce local stress, improve the stability and assembly convenience of the power box and the base, and extend the service life of the power box.

[0021] Preferably, the front shell has a pryable buckle on its side, and the rear shell has a mating part. The buckle and the mating part cooperate to lock or unlock the front shell and the rear shell.

[0022] In this embodiment, when it is necessary to unlock the front and rear shells, the buckles can be pried outwards to open them. This design facilitates the disassembly and installation of the front and rear shells and is easy to operate. It does not require complex or excessive parts for fixing, simplifies the assembly process, saves time and improves work efficiency.

[0023] Preferably, the power supply box has a wire clip on the side away from the guide groove to accommodate at least part of the power cord.

[0024] In this embodiment, the cable clip is provided to store the power cord together and secure it inside the clip, which can tidy up the messy lines and make it look more aesthetically pleasing. It also prevents the power cord from being squeezed or pulled during the installation or removal of the power box. In addition, the cable clip also makes it easy to lift the power box from the base by holding it in the cable clip with both hands, which is convenient and saves effort.

[0025] Preferably, the front shell has a plurality of spaced-apart heat dissipation holes on the side away from the rear shell.

[0026] In this embodiment, the multiple spaced heat dissipation holes can promote air circulation, accelerate the dissipation of heat inside the equipment, prevent overheating, and ensure stable operation of the equipment.

[0027] A dishwasher includes the mounting structure of the power supply box described above. Attached Figure Description

Therefore, the above terms should not be construed as limitations on this application.

[0041] The present application will now be described in further detail with reference to the accompanying drawings, see below. Figures 1 to 7 illustrate.

[0042] This embodiment provides a power supply box mounting structure, which is applied in the field of dishwasher technology. Specifically, as shown in... Figures 1 to 7As shown, the assembly includes a power box 2 housed within a base 1 and at least one bolt 3. A snap-fit ​​component 11 is provided on the side of the base 1 facing the power box 2. The power box 2 has a guide groove 21 extending from its top to its bottom. The snap-fit ​​component 11 corresponds to and engages with the guide groove 21 to guide and position the base 1 and the power box 2. The snap-fit ​​component 11 also serves a guiding and positioning function, enabling faster and more convenient installation of the power box 2 to the base 1, thus improving work efficiency. The power box 2 and the base 1 are fixedly connected by the bolt 3. The assembly direction of the bolt 3 is perpendicular to the assembly direction of the snap-fit ​​component 11. When the bolt 3 is removed, the power box 2 can be lifted upwards for disassembly or replacement, resulting in good stability for the power box 2. This eliminates the need for other fixing structures, saving assembly time and steps, reducing costs and time, and further improving work efficiency.

[0043] Furthermore, such as Figures 2 to 3 As shown, the lower part of the guide groove 21 is provided with an annular protrusion 211. The annular protrusion 211 is located at the bottom of the guide groove 21 and is radially protruding. The annular protrusion 211 is used to limit or support the snap-fit ​​component 11. The annular protrusion 211 can prevent the power box 2 from running off-center, misaligned or displaced during installation. At the same time, the annular protrusion 211 also limits the snap-fit ​​component 11 to accurately position the power box 2.

[0044] Furthermore, such as Figure 1 , Figure 7 As shown, the power supply box 2 is provided with at least one hanging member 26 on the side facing the base 1. The bottom of the hanging member 26 cooperates with the top of the base 1 to realize the connection between the power supply box 2 and the base 1. When there is one hanging member 26, the hanging member 26 is located in the middle position of the power supply box 2. When there are two hanging members 26, the two hanging members 26 are spaced apart on one side of the guide groove 21. By setting the hanging member 26, the connection strength between the power supply box 2 and the base 1 can be improved to prevent loosening or falling off. It can also make it easy for the power supply box 2 to be hung on the base 1, which is convenient for quick installation and disassembly. At the same time, it is also convenient for later inspection and maintenance, improving work efficiency.

[0045] Furthermore, such as Figures 5 to 6 As shown, the diameter of the upper groove of the guide groove 21 is larger than the diameter of the lower groove. The purpose of setting a larger upper groove diameter is to facilitate mold demolding during injection molding, reduce molding difficulty, reduce production costs and time, and improve production efficiency.

[0046] Furthermore, such as Figures 2 to 6As shown, the guide groove 21 is recessed towards the center of the power supply box 2. The depth of the recess is adapted to the size of the snap-fit ​​component 11. The design of the guide groove 21 not only facilitates the smooth sliding of the snap-fit ​​component 11, but also enhances the connection stability between the base 1 and the power supply box 2. The guide groove 21 is an arc-shaped groove with arc-shaped transitions on both sides. The arc-shaped groove can reduce resistance and friction during the installation of the power supply box 2, improving the convenience and efficiency of installation.

[0047] Furthermore, such as Figure 7 As shown, the power supply box 2 includes a front shell 22 and a rear shell 23 that are interlocked and fixed together. A power board 25 is fixed within the space formed by the front shell 22 and the rear shell 23. When the power board 25 needs to be replaced or maintained, the interlocking connection facilitates the disassembly and installation of the front shell 22 and the rear shell 23, thus improving assembly efficiency. The front shell 22 has mounting holes, and the rear shell 23, the power board 25, and the base 1 all have through holes. Bolts 3 pass through the front shell 22, the power board 25, and the rear shell 23 sequentially until they connect to the base 1.

[0048] Among them, such as Figure 5 As shown, the guide groove 21 is located on the side of the rear shell 23 away from the front shell 22. The guide groove 21 is eccentrically positioned, deviating from the center of the rear shell 23 and away from the bolt 3. This eccentric positioning keeps the guide groove 21 away from the bolt 3, which can prevent stress concentration near the bolt 3 hole, reduce local stress, improve the stability and ease of assembly of the power supply box 2 and the base 1, and extend the service life of the power supply box 2.

[0049] like Figure 5 , Figure 7 As shown, the front shell 22 has a pryable latch 221 on its side, and the rear shell 23 has a mating part 231. The latch 221 engages with the mating part 231 to lock or unlock the front shell 22 and the rear shell 23. A mating block is provided on the side of the latch 221 facing the mating part 231, and the mating block engages with the mating part 231 to lock the front shell 22 and the rear shell 23. When it is necessary to unlock the front shell 22 and the rear shell 23, the latch 221 is pried open outwards to open them. This design facilitates the disassembly and installation of the front shell 22 and the rear shell 23, and is easy to operate. It does not require complex or excessive parts for fixing, simplifies the assembly process, saves time, and improves work efficiency.

[0050] Furthermore, such as Figure 5 , Figure 7As shown, the power supply box 2 has a wire clip 24 on the side away from the guide groove 21 to accommodate at least part of the power cord. The wire clip 24 is hook-shaped, and there are at least two wire clips 24. The two wire clips 24 are located on the side of the power supply box 2 in the width direction. The wire clips 24 and the buckles 221 are both located on the same side of the power supply box 2. The wire clips 24 are set on the back shell 23. The purpose of setting the wire clips 24 is to store the power cord together and buckle 221 inside the wire clips 24. This can tidy up the messy lines and make them look more beautiful. It also prevents the power cord from being squeezed or pulled during the installation or removal of the power supply box 2. In addition, the wire clips 24 can also be used to lift the power supply box 2 by holding it with both hands when removing it from the base 1, which is convenient and saves effort.

[0051] Among them, such as Figure 4 , Figure 7 As shown, the front shell 22 has a plurality of spaced heat dissipation holes 222 on the side away from the rear shell 23. The plurality of heat dissipation holes 222 are eccentrically arranged and spaced apart to promote air circulation, accelerate the dissipation of heat inside the equipment, prevent overheating, and ensure stable operation of the equipment.
