In addition, features defined as "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present utility model, unless otherwise specified, "multiple" means two or more.

[0046] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0047] The electric control box 100 according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

[0048] like Figure 1-Figure 3 , Fig.13 and Fig.14 As shown, the electric control box 100 according to the embodiment of the utility model is used in a dishwasher 1000 , and the electric control box 100 includes an upper box 11 and a lower box 12 .

[0049] The upper surface of the upper box 11 has an inclined surface 111, and the upper box 11 is provided with an inclined surface 111 in the length direction (such as Fig.13 In the direction from one end to the other end (the first direction shown in the figure), the inclined surface 111 is inclined downward, the upper box 11 is connected to the lower box 12, and in the thickness direction of the electric control box 100, the projection area of ​​the upper box 11 is larger than the projection area of ​​the lower box 12.

[0050] Therefore, when the liquid flows to the upper surface of the upper box 11, the upper surface of the upper box 11 has an inclined surface 111, and the inclined surface 111 is inclined downward in the direction from one end to the other end of the length direction of the upper box 11, so that the liquid located on the upper surface of the upper box 11 flows downward along the inclined surface 111 and flows out from the lower end of the two ends of the length direction of the upper box 11 to a specific area, thereby avoiding the accumulation of liquid on the upper surface of the upper box 11, and further avoiding the accumulation and retention of liquid on the upper surface of the upper box 11 and overflowing into the interior of the electric control box 100 to damage the electric control components located in the electric control box 100, so that the electric control box 100 meets the waterproof requirements.

[0051] At the same time, in the thickness direction of the electric control box 100, the projection area of ​​the upper box 11 is larger than the projection area of ​​the lower box 12, thereby blocking the liquid from flowing from the upper box 11 to the lower box 12, and preventing the liquid from entering the interior of the electric control box 100 from the connection between the upper box 11 and the lower box 12, thereby further improving the waterproof effect of the electric control box 100, and then improving the reliability and safety of the electric control box 100 and the dishwasher 1000 using the electric control box 100.

[0052] In addition, when the electronic control box 100 is applied to the dishwasher 1000, there is a wiring harness at the bottom of the electronic control box 100. The liquid on the upper surface of the upper box 11 flows downward along the inclined surface 111 and flows out from the lower end of the upper box 11 in the length direction, thereby guiding the liquid to flow to a specific area and reducing the liquid from flowing downward along the side of the upper box 11 and wetting the wiring harness, especially the wiring harness terminals of the wiring harness, causing short circuits, corrosion or poor contact, thereby affecting the stability and safety of the electronic control system of the entire dishwasher 1000.

[0053] Compared with the prior art in which other components are added to the electric control box to make the electric control box meet the waterproof requirements, the inclined surface 111 of the electric control box 100 of the present application has a simple structure and does not require other components. The electric control box 100 itself can meet the waterproof requirements, thereby reducing the production difficulty and production cost of the electric control box 100.

[0054] According to the electric control box 100 of the embodiment of the utility model, the electric control box 100 includes an upper box 11 and a lower box 12. The upper surface of the upper box 11 has an inclined surface 111. In the direction from one end to the other end of the length direction of the upper box 11, the inclined surface 111 is arranged to be inclined downward, so that the liquid located on the upper surface of the upper box 11 flows downward along the inclined surface 111 and flows out from the lower end of the two ends of the length direction of the upper box 11 to a specific area, thereby avoiding the accumulation of liquid on the upper surface of the upper box 11, and further avoiding the accumulation and retention of liquid on the upper surface of the upper box 11 and overflowing into the electric control box 100 to damage the electric control components located in the electric control box 100, so that the electric control box 100 meets the waterproof requirements. At the same time, by connecting the upper box 11 to the lower box 12, in the thickness direction of the electric control box 100, the projected area of ​​the upper box 11 is larger than the projected area of ​​the lower box 12, thereby blocking the liquid from flowing from the upper box 11 to the lower box 12, further improving the waterproof effect of the electric control box 100, and further improving the reliability and safety of the electric control box 100 and the dishwasher 1000 using the electric control box 100.

[0055] In some embodiments of the present invention, Figure 3 and Fig.13 As shown, there are multiple inclined surfaces 111 and include a first sub-surface 1111 and a second sub-surface 1112 arranged along the length direction of the upper box 11. The first sub-surface 1111 is inclined downward in a direction away from the second sub-surface 1112, and the second sub-surface 1112 is inclined downward in a direction away from the first sub-surface 1111.

[0056] It can be understood that, through such an arrangement, the ends of the first sub-surface 1111 and the second sub-surface 1112 close to each other are the highest point, the end of the first sub-surface 1111 away from the second sub-surface 1112 is the lowest point, and the end of the second sub-surface 1112 away from the first sub-surface 1111 is the lowest point. Therefore, when the liquid flows to the first sub-surface 1111, the liquid flows along the first sub-surface 1111 to the end of the first sub-surface 1111 away from the second sub-surface 1112, and when the liquid flows to the second sub-surface 1112, the liquid flows along the second sub-surface 1112 to the end of the second sub-surface 1112 away from the first sub-surface 1111, thereby preventing the liquid from accumulating on the upper surface of the upper box 11, and further preventing the liquid from accumulating and stagnating on the upper surface of the upper box 11 and overflowing into the electric control box 100 to damage the electric control components located in the electric control box 100.

[0057] In some embodiments of the utility model, the inclined surface 111 extends from one end to the other end in the length direction of the upper box 11. It can be understood that, through such a setting, one end of the inclined surface 111 along the length direction of the upper box 11 is the highest point, and the other end is the lowest point. Therefore, when the liquid flows to the upper surface of the upper box 11, the liquid flows along the inclined surface 111 to the lowest point, thereby preventing the liquid from accumulating on the upper surface of the upper box 11, and further preventing the liquid from accumulating and stagnating on the upper surface of the upper box 11 and overflowing into the electric control box 100 to damage the electric control components located in the electric control box 100.

[0058] In some embodiments of the present invention, Figure 3 and Fig.13 As shown, the inclined surface 111 includes a first inclined surface 1113 and a second inclined surface 1114. The first inclined surface 1113 and the second inclined surface 1114 are arranged in a thickness direction of the upper box 11 (eg, Fig.13 The first bevel 1113 and the second bevel 1114 are arranged in the second direction as shown, the height of the first bevel 1113 is higher than the height of the second bevel 1114, the first bevel 1113 and the second bevel 1114 form a step, and the second bevel 1114 extends from one end of the first bevel 1113 to one end of the upper box 11 in the thickness direction.

[0059] It can be understood that when the liquid flows to the first slope 1113, the liquid flows downward along the first slope 1113, wherein part of the liquid flows out from the lower end of the two ends in the length direction of the upper box 11, and the remaining part of the liquid flows from the first slope 1113 to the second slope 1114 and flows downward along the second slope 1114 and flows out from the lower end of the two ends in the length direction of the upper box 11; or, when the liquid flows to the second slope 1114, the liquid flows downward along the second slope 1114 and flows out from the lower end of the two ends in the length direction of the upper box 11; or, when the liquid flows to the first slope 1113 and the second slope 1114, the liquid on the first slope 1113 flows downward and flows out from the lower end of the two ends in the length direction of the upper box 11, and the remaining part of the liquid flows from the first slope 1113 to the second slope 1114 and then merges with the liquid on the second slope 1114 and flows downward along the second slope 1114.

[0060] Therefore, such a setting further optimizes the drainage path of the inclined surface 111, further preventing liquid from accumulating and stagnating on the upper surface of the upper box 11 and seeping into the interior of the electric control box 100 to damage the electric control components inside the electric control box 100, and preventing liquid from flowing downward along the side of the upper box 11 and wetting the wiring harness, especially the wiring harness terminals, thereby further improving the reliability and safety of the electric control box 100.

[0061] In some embodiments of the present invention, Figure 3 and Fig.13As shown, the surface of the upper box 11 facing away from the lower box 12 has a protruding water guide rib 112 , and the water guide rib 112 is arranged to be inclined downward in at least a portion of the length direction of the upper box 11 .

[0062] It is understandable that when the flow rate of the liquid flowing to the upper surface of the upper box 11 is large, there is a possibility that part of the liquid flows downward along the side wall of the upper box 11. Therefore, the liquid flowing downward from the upper surface of the upper box 11 along the side wall of the upper box 11 is effectively blocked by the water guide ribs 112 from continuing to flow downward, and the water guide ribs 112 are arranged to be tilted downward at least in a portion of the length direction of the upper box 11, so that the liquid flows downward along the water guide ribs 112 and flows out from the lower end, and the liquid is guided to flow to a specific area, thereby avoiding wetting the wiring harness located below the electric control box 100, especially the wiring harness terminals of the wiring harness, resulting in short circuit, corrosion or poor contact, and further improving the reliability and safety of the electric control box 100.

[0063] In some embodiments of the present invention, Figure 3 and Fig.13 As shown, the water guiding ribs 112 are multiple and include a first sub-rib 1121 and a second sub-rib 1122 connected in the length direction of the upper box 11, the first sub-rib 1121 is inclined downward in a direction away from the second sub-rib 1122, and the second sub-rib 1122 is inclined downward in a direction away from the first sub-rib 1121.

[0064] It is understandable that, through such an arrangement, the ends of the first sub-rib 1121 and the second sub-rib 1122 close to each other are the highest point, the end of the first sub-rib 1121 away from the second sub-rib 1122 is the lowest point, and the end of the second sub-rib 1122 away from the first sub-rib 1121 is the lowest point. Thus, when the liquid flows downward along the side wall of the upper box 11 to the water guide rib 112, the liquid flows along the first sub-rib 1121 to the end of the first sub-rib 1121 away from the second sub-rib 1122, and when the liquid flows to the second sub-rib 1122, the liquid flows along the second sub-rib 1122 to the end of the second sub-rib 1122 away from the first sub-rib 1121, thereby preventing the liquid flowing downward along the side of the upper box 11 from continuing to flow downward, thereby improving the reliability and safety of the electric control box 100.

[0065] Optionally, the water guide ribs 112 are multiple and spaced apart along the height direction of the electric control box 100. Thus, such an arrangement further blocks the liquid flowing downward along the side of the upper box 11 from continuing to flow downward, thereby improving the reliability and safety of the electric control box 100.

[0066] In some embodiments of the utility model, the water guide rib 112 extends from one end to the other end in the length direction of the upper box 11. It can be understood that, through such a configuration, one end of the water guide rib 112 along the length direction of the upper box 11 is the highest point, and the other end is the lowest point. Therefore, when the liquid flows downward along the side wall of the upper box 11 to the water guide rib 112, the liquid flows toward the lowest point along the water guide rib 112, thereby preventing the liquid flowing downward along the side of the upper box 11 from continuing to flow downward, thereby improving the reliability and safety of the electric control box 100.

[0067] The dishwasher 1000 according to the embodiment of the present invention is described below.

[0068] According to the dishwasher 1000 of the present utility model, Figure 1-Figure 14 As shown, it includes a base 200 and an electric control box 100. The base 200 includes a bottom plate 21 and a plurality of side plates 22. The plurality of side plates 22 and the bottom plate 21 surround a storage space 2 of the base 200. The electric control box 100 is installed obliquely in the storage space 2. The electric control box 100 is arranged obliquely relative to the bottom plate 21.

[0069] It is understandable that after the electric control box 100 is assembled, the length direction (eg Fig.13 The first direction shown in FIG. 1 may be the front-to-back direction of the dishwasher 1000, and the thickness direction of the electric control box 100 (such as Fig.13 The second direction shown) can be the left-right direction of the dishwasher.

[0070] Therefore, the base 200 includes a bottom plate 21 and multiple side plates 22, and the multiple side plates 22 and the bottom plate 21 surround the base 200 to form a storage space 2, and the electric control box 100 is installed in the storage space 2, so that the side plates 22 and the bottom plate 21 play a certain protective role on the electric control box 100, thereby improving the reliability of the dishwasher 1000.

[0071] Thus, when the liquid flows to the upper surface of the upper box 11, the upper surface of the upper box 11 has an inclined surface 111, and the inclined surface 111 is arranged to be inclined downward in the direction from one end to the other end in the length direction of the upper box 11, so that the liquid on the upper surface of the upper box 11 flows downward along the inclined surface 111 and flows out from the lower end of the two ends in the length direction of the upper box 11 to a specific area, thereby preventing the liquid from accumulating on the upper surface of the upper box 11, and further preventing the liquid from accumulating and stagnating on the upper surface of the upper box 11 and overflowing into the electric control box 100 to damage the electric control components located in the electric control box 100. At the same time, in the thickness direction of the electric control box 100, the projection area of ​​the upper box 11 is larger than the projection area of ​​the lower box 12, thereby preventing the liquid from flowing from the upper box 11 to the lower box 12, further improving the waterproof effect of the electric control box 100, and further improving the reliability and safety of the dishwasher 1000.

[0072] In addition, by obliquely installing the electric control box 100 in the accommodating space 2, the electric control box 100 is inclined relative to the bottom plate 21, which can reduce the space occupied by the electric control box 100 on the chassis, facilitate the layout of other components on the chassis, and improve space utilization.

[0073] Furthermore, the upper end of the electric control box 100 is inclined toward the outside of the base 200, and the inclined surface 111 is inclined downward in the direction from the inside to the outside of the base 200. Thus, the liquid on the upper surface of the upper box 11 flows downward along the inclined surface 111 and flows out from the lower end of the two ends in the length direction of the upper box 11 to a specific area, and the liquid on the inclined surface 111 is blocked from flowing toward the inside of the base 200, thereby further optimizing the drainage path of the inclined surface 111 and improving the reliability and safety of the dishwasher 1000.

[0074] Furthermore, the bottom plate 21 is parallel to the horizontal plane, and the angle between the electric control box 100 and the horizontal plane is 40°-60°. Thus, by limiting the angle between the electric control box 100 and the horizontal plane, the stability of the electric control box 100 is ensured, and the electric control box 100 is prevented from moving or tipping over when subjected to external impact or vibration, thereby improving reliability, reducing assembly difficulty, and improving assembly efficiency.

[0075] Optionally, the angle between the electric control box 100 and the horizontal plane may be 40°, 45°, 50°, 55° or 60°.

[0076] Optionally, the angle between the upper box 11 and the horizontal plane is 40°-60°.

[0077] According to the dishwasher 1000 of the embodiment of the utility model, an electric control box 100 is provided, and the base 200 includes a bottom plate 21 and a plurality of side plates 22. The plurality of side plates 22 and the bottom plate 21 surround and form a receiving space 2 of the base 200. The electric control box 100 is installed obliquely in the receiving space 2. The electric control box 100 is arranged obliquely relative to the bottom plate 21, which can reduce the space occupied by the electric control box 100 in the chassis, facilitate the layout of other components on the chassis, and improve the space utilization rate. At the same time, the upper surface of the upper box 11 has an inclined surface 111, and the inclined surface 111 is arranged downwardly in a direction from one end to the other end of the length direction of the upper box 11. In the thickness direction of the electric control box 100, the projection area of ​​the upper box 11 is larger than the projection area of ​​the lower box 12, thereby blocking the liquid from flowing from the upper box 11 to the lower box 12, so that the electric control box 100 meets the waterproof requirements and improves the reliability and safety of the electric control dishwasher 1000.

[0078] In some embodiments of the present invention, Figure 1-Figure 14As shown, the dishwasher 1000 also includes an inner tank 300, which is installed above the base 200, the upper box 11 is located above the lower box 12, the orthographic projection of the upper box 11 covers the orthographic projection of the lower box 12, and the inclined surface 111 of the upper box 11 is arranged toward one side of the inner tank 300.

[0079] Therefore, by positioning the upper box 11 above the lower box 12, the orthographic projection of the upper box 11 covers the orthographic projection of the lower box 12, so that the liquid flowing from above the electric control box 100 to the electric control box 100 all flows to the upper box 11, effectively blocking the liquid from flowing to the lower box 12, and preventing the liquid from entering the interior of the electric control box 100 from the connection between the upper box 11 and the lower box 12, thereby ensuring the waterproof effect of the electric control box 100.

[0080] At the same time, the liquid flowing on the upper surface of the upper box 11 flows downward along the inclined surface 111 and flows out from the lower end of the two ends in the length direction of the upper box 11 to a specific area, thereby preventing the liquid from accumulating on the upper surface of the upper box 11, and further preventing the liquid from accumulating and stagnating on the upper surface of the upper box 11 and overflowing into the electric control box 100 to damage the electric control components located in the electric control box 100, so that the electric control box 100 meets the waterproof requirements. In addition, by setting the inclined surface 111 of the upper box 11 toward one side of the inner tank 300, it is convenient for the liquid flowing downward along the surface of the inner tank 300 to flow to the inclined surface 111, further optimizing the drainage path, improving the waterproof effect of the electric control box 100, and thus improving the reliability and safety of the dishwasher 1000.

[0081] In some embodiments of the present invention, Figure 3 , Figure 5 and Figure 6 As shown, the base 200 further includes a support plate 3, which is connected to at least one side plate 22, and has a support surface 32, which is inclined upward from the inside to the outside of the base 200, and the lower box 12 of the electric control box 100 abuts against the support surface 32. Thus, through the support of the support plate 3 on the lower box 12, the stability of the inclined electric control box 100 is ensured, and the electric control box 100 is prevented from moving or tipping over when subjected to external impact or vibration, thereby improving the overall reliability.

[0082] Furthermore, if Figure 6 As shown, the support plates 3 are multiple and spaced apart along the length direction of the box body 1. Thus, the side of the electric control box 100 away from the center of the dishwasher 1000 is supported on the multiple support plates 3, thereby further ensuring the stability of the inclined electric control box 100, preventing the electric control box 100 from moving or falling when subjected to external impact or vibration, and improving the overall reliability.

[0083] In some embodiments of the present invention, Figure 2-Figure 14As shown, there are multiple support plates 3, and mounting posts 121 are provided at both ends of the lower box 12. At least two support plates 3 have mounting notches 31 corresponding to the two mounting posts 121, and the mounting posts 121 are clamped in the mounting notches 31. Thus, the electric control box 100 is connected to the base 200 through the cooperation of the mounting posts 121 and the mounting notches 31. At the same time, the mounting posts 121 are provided at both ends of the lower box 12 to ensure the stability of the electric control box 100 after assembly. In addition, the setting of the inclined surface 111 can effectively prevent liquid from flowing into the matching position of the mounting posts 121 and the mounting notches 31 to cause corrosion and deformation, so that the electric control box 100 and the base 200 can be repeatedly disassembled and assembled, which is convenient for the maintenance of the thick electric control box 100.

[0084] In some embodiments of the present invention, Fig. 9 and Fig.12 As shown, in the direction from the open mouth to the bottom end of the mounting notch 31, the mounting notch 31 includes a first notch section 311 and a second notch section 312 in sequence, the mounting column 121 is suitable for being located in the second notch section 312, the width of the end of the second notch section 312 close to the first notch section 311 is smaller than the maximum diameter of the mounting column 121, and in the direction from the first notch section 311 to the second notch section 312, the width of the first notch section 311 gradually decreases.

[0085] It can be understood that, since the width of the end of the second notch section 312 close to the first notch section 311 is smaller than the maximum diameter of the mounting post 121, and the support plate 3 at the mounting notch 31 has a certain deformation ability, when the mounting post 121 enters the second notch section 312 from the first notch section 311, the support plate 3 utilizes the elastic deformation of the support plate 3 to enter the second notch section 312, and after the mounting post 121 is located in the second notch section 312, the support plate 3 returns to its original state, and the width of the end of the second notch section 312 close to the first notch section 311 is smaller than the maximum diameter of the mounting post 121, so as to limit the movement of the mounting post 121 toward the first notch section 311, thereby achieving the cooperation between the mounting post 121 and the mounting notch 31, thereby achieving the assembly of the electric control box 100 and the base 200, and such a setting facilitates the disassembly and assembly of the electric control box 100 and subsequent maintenance.

[0086] At the same time, in the direction from the first notch section 311 to the second notch section 312, the width of the first notch section 311 is gradually reduced, so that the first notch section 311 plays a certain guiding role, which facilitates the installation column 121 to enter the installation notch 31 from the first notch section 311, thereby reducing the difficulty of assembly and improving the assembly efficiency.

[0087] Furthermore, the maximum diameter of the mounting column 121 is ≥3 mm. Thus, the structural strength of the mounting column 121 is ensured through such a configuration, and the reliability is further improved.

[0088] In some embodiments of the present invention, Fig. 9 and Fig.12 As shown, deformation notches 313 are respectively provided on the inner walls of the two sides opposite to the end of the second notch section 312 away from the first notch section 311, and the mounting post 121 is clamped in the second notch section 312 and abuts against the inner walls of the deformation notches 313. Therefore, in the process of the mounting post 121 entering the second notch section 312 from the first notch section 311 or the mounting post 121 entering the first notch section 311 from the second notch section 312, the deformation ability of the support plate 3 is guaranteed by the setting of the deformation notches 313, and repeated disassembly and assembly are achieved without damaging the support plate 3 and the support post, which further facilitates the disassembly and assembly of the electric control box 100, reduces the difficulty of assembly and disassembly, and facilitates maintenance.

[0089] In some embodiments of the present invention, Fig. 9 and Fig.12 As shown, in the direction from the open mouth to the bottom end of the installation notch 31, the width of the first notch section 311 gradually decreases, and the first notch section 311 includes a first sub-segment 3111 and a second sub-segment 3112. The two opposite inner walls of the first sub-segment 3111 are planes, and the two opposite inner walls of the second sub-segment 3112 are curved surfaces convex away from each other.

[0090] Thus, by gradually reducing the width of the first notch segment 311, the first notch segment 311 includes a first sub-segment 3111 and a second sub-segment 3112. In the process of the installation column 121 entering the installation notch 31 from the first notch segment 311, the first sub-segment 3111 guides the installation column 121 to enter the installation notch 31, thereby further reducing the difficulty of assembly, and the structural setting of the straight section is relatively simple.

[0091] At the same time, the two opposite inner walls of the second sub-segment 3112 are curved surfaces convex away from each other, which facilitates the arc transition connection between the second sub-segment 3112 and the second notch segment 312, and facilitates the installation column 121 to enter the second notch segment 312 from the first notch segment 311 or the installation column 121 to enter the first notch segment 311 from the second notch segment 312, thereby further improving reliability.

[0092] In some embodiments of the present invention, Figure 5 , Figure 6 and Fig.14As shown, a mounting portion 122 is provided on the side of the lower box 12 facing the bottom plate 21, and a first mounting hole 1221 is provided on the mounting portion 122. The bottom plate 21 has a second mounting hole 211 arranged opposite to the first mounting hole 1221, and a fastener passes through the second mounting hole 211 and is fastened to the second mounting hole 211. Thus, through such an arrangement, the fastener passes through the second mounting hole 211 and the first mounting hole 1221 in sequence from bottom to top and is fastened to the second mounting hole 211, thereby achieving a fixed connection between the electric control box 100 and the base 200 and achieving the assembly of the two. At the same time, the arrangement of the inclined surface 111 can effectively prevent liquid from invading the fastener and causing corrosion and deformation thereof, so that the electric control box 100 and the base 200 can be repeatedly disassembled and assembled, which is convenient for the maintenance of the thick electric control box 100.

[0093] Furthermore, the fastener passes through the second mounting hole 211 and is threadedly connected to the second mounting hole 211, thereby reducing the space occupied by the fastener on the chassis, facilitating the layout of other components on the chassis, and improving space utilization.

[0094] Furthermore, there is one mounting portion 122 and one second mounting hole 211; or, there are multiple mounting portions 122 spaced apart along the length direction of the lower box 12, and there are multiple second mounting holes 211 corresponding to the mounting portions 122. Thus, such a setting can improve the versatility of the electric control box 100 and meet the needs of different dishwashers 1000.

[0095] In some embodiments, Figure 3-Figure 6 and Fig.14 As shown, mounting posts 121 are provided at both ends of the lower box 12, at least two support plates 3 respectively have mounting notches 31 corresponding to the two mounting posts 121, the mounting posts 121 are snapped into the mounting notches 31, a mounting portion 122 is provided on the side of the lower box 12 facing the bottom plate 21, the mounting portion 122 has a first mounting hole 1221, the bottom plate 21 has a second mounting hole 211 arranged opposite to the first mounting hole 1221, and a fastener passes through the second mounting hole 211 and is fastened to the second mounting hole 211.

[0096] Therefore, mounting columns 121 are provided at both ends of the lower box 12 and are clamped in the corresponding mounting notches 31, and a mounting portion 122 is provided on the side of the lower box 12 facing the bottom plate 21 and is fastened to the bottom plate 21 through fasteners, thereby ensuring the assembly strength of the lower box 12 and the base 200, ensuring the stability of the tilted electric control box 100, and improving the reliability of the dishwasher 1000.
