[0043] Referring to Figure 2 and Figure 3 The base 100 comprises a chassis 110 and a surrounding plate 120 connected with the chassis 110. The surrounding plate 120 cooperates with the chassis 110 to define an electric control box mounting area 10A and a mounting groove 10B. It can be understood that the surrounding plate 120 comprises four side plates, the bottom walls of the four side plates are connected with the chassis 110 and sequentially abut each other. The liner mounting groove 10B and the electric control box mounting area 10A are arranged at intervals. The liner mounting groove 10B is used for accommodating part of the structure of the liner assembly. The liner mounting groove 10B and the electric control box mounting area 10A are spaced apart by the chassis 110 and the surrounding plate 120, which can facilitate the installation of the electric control box 200 and the liner, and can avoid the interference of the electric control box 200 and the liner. The surrounding plate 120 comprises a first side plate 121, which is located between the electric control box mounting area 10A and the mounting groove 10B and is provided with a first wire port 120b and a second wire port 120c arranged at intervals. The first wire port 120b and the second wire port 120c are in communication with the electric control box mounting area 10A and the liner mounting groove 10B.

[0044] It should be noted that the base 100 and the surrounding plate 120 can be injection molded by using a plastic material, for example but not limited to polyethylene (PE), polypropylene (PP), polyvinyl chloride (PVC), polystyrene (PS), polycarbonate (PC), polyamide (PA) and polyester (PET). The base 100 and the surrounding plate 120 can be a split structure, and then be fixed together by one or more forms of clamping, screwing, welding and the like, or be injection molded as an integral structure.

[0045] The electric control box 200 is installed in the electric control box installation area 10A, and the electric control box 200 includes a box body and a circuit board arranged in the box body, and the circuit board has a strong current area and a weak current area arranged at intervals; the strong current area is connected with a strong current wire 210, and the strong current wire 210 is used to transmit a high-voltage current to drive a motor, a heater and other high-power components of the dishwasher 1. The weak current area is connected with a weak current wire 220, and the weak current wire 220 is used to transmit a low-voltage signal and a control current to transmit the user's instructions and the state information of the dishwasher 1 to the microprocessor or other control elements on the circuit board, so as to realize the automatic control of the dishwasher 1.

[0046] A plurality of fixed wire buckles 300 are connected to the groove wall of the inner container installation groove 10B, please refer to Figure 2 , a plurality of fixed wire buckles 300 are arranged along the groove wall of the inner container installation groove 10B to form a first wire path 10C corresponding to the first wire outlet 120b and a second wire path 10D corresponding to the second wire outlet 120c, wherein the first wire path 10C and the second wire path 10D do not coincide.

[0047] The electric wire of the electric control box 200 needs to be connected with the parts of the inner container to control the operation of the dishwasher 1. Please refer to Figure 2 and Figure 3 In this application, the strong current wire 210 connected with the strong current area extends into the inner container installation groove 10B through the first wire outlet 120b and extends along the first wire path 10C, and the weak current wire 220 connected with the weak current area extends into the inner container installation groove 10B through the second wire outlet 120c and extends along the second wire path 10D, so that the strong current wire 210 and the weak current wire 220 of the electric control box 200 can extend into the inner container installation groove 10B through the first wire outlet 120b and the second wire outlet 120c respectively, and extend and arrange through the first wire path 10C and the second wire path 10D respectively, and then be connected with the electrical parts in the inner container installation groove 10B. Since the strong current wire 210 and the weak current wire 220 are arranged through different wire outlets and wire paths respectively, direct contact between them is effectively avoided, the risk of electrical interference and short circuit is reduced, and the electrical safety of the dishwasher 1 is improved. Moreover, the current transmitted by the strong current wire 210 is large, which may generate a certain amount of heat. By arranging different wire paths, the heat transfer between the strong current wire 210 and the weak current wire 220 can be avoided, and the stability of the entire electrical system is improved. In addition, when the electric wire needs to be repaired or replaced, the corresponding electric wire can be more easily confirmed and operated, thereby improving the convenience of maintenance.

[0048] The inner container installation groove 10B includes a first groove wall 1211 and two second groove walls 122 respectively located on opposite sides of the first groove wall 1211, the first groove wall 1211 is provided with a first wire outlet 120b and a second wire outlet 120c, and the inner container installation groove 10B and the electric control box 200 installation area 10A are located on opposite sides of the first groove wall 1211; the first wire path 10C extends from the first groove wall 1211 towards one of the second groove walls 122, and the second wire path 10D extends from the first groove wall 1211 towards the other second groove wall 122 in a direction opposite to the first wire path 10C. It can be understood that the first side plate 121 forms the first groove wall 1211, and the two second groove walls 122 are formed by the side plates located on opposite sides of the first side plate 121. In the present application, the first wire outlet 120b and the second wire outlet 120c are arranged on the first groove wall 1211, and the first wire path 10C and the second wire path 10D extend towards the two second groove walls 122 respectively, which effectively utilizes the space in the inner container installation groove 10B, avoids the occupation of the installation space of other components by the wires, and makes the arrangement of the wires more reasonable and orderly. Moreover, since the first wire path 10C and the second wire path 10D extend towards different second groove walls 122 respectively, the distance between them is relatively far, which helps to reduce the electromagnetic interference of the high-voltage current transmitted by the strong wire 210 on the signal transmitted by the weak wire 220, thereby improving the automation control precision and stability of the dishwasher 1.

[0049] Please refer to Figure 4 The fixed wire buckle 300 includes a first wire buckle 310 arranged adjacent to the first groove wall 1211 and a second wire buckle 320 connected to the second groove wall 122, and the first wire path 10C and the second wire path 10D both include the first wire buckle 310 and the second wire buckle 320. The first wire buckle 310 and the second wire buckle 320 of the present application can be connected with the bottom disc 110, or can be connected with the groove side wall of the inner container installation groove 10B, that is, with the surrounding plate 120, or can be connected with both the bottom disc 110 and the surrounding plate 120, which is not limited in the present application.

[0050] Please refer to Figure 4 The first wire buckle 310 has a first buckle wire groove 310A, and the second wire buckle 320 has a second buckle wire groove 320A, and the openings of the first buckle wire groove 310A and the second buckle wire groove 320A are different. It can be understood that there is a corner area between the first groove wall 1211 and the second groove wall 122, and when the wire is drawn out from the first buckle wire groove 310A of the first groove wall 1211, it needs a certain bending angle to transition into the second buckle wire groove 320A of the second groove wall 122. However, by setting the openings of the first buckle wire groove 310A and the second buckle wire groove 320A to be different, the wire can be easily clamped in the first buckle wire groove 310A, and the fixing effect can be improved in the second buckle wire groove 320A.

[0051] In some embodiments, referring to Figure 4 The first wire buckle 310 includes two first sub-buckles 311, each of which includes a first connecting portion 3111 connected to the bottom plate 110 and a first clamping portion 3112 connected to the first connecting portion 3111. The first clamping portions 3112 of the two first sub-buckles 311 are oppositely arranged and define a first buckle slot 310A having an upward opening. The opening of the first buckle slot 310A is arranged upward, so that the electric wire can be fixed in the first buckle slot 310A by being pressed downward. When the electric wire is bent, the electric wire can be effectively clamped by the first sub-buckle 311 to prevent the electric wire from coming off the first buckle slot 310A.

[0052] In some embodiments, referring to Figure 4 The first wire buckle 310 further includes a first connecting plate 312 connected to both sides of the first connecting portions 3111 of the two first sub-buckles 311 and the bottom plate 110. The top of the first connecting plate 312 forms a slot bottom wall of the first buckle slot 310A, and the slot bottom wall of the first buckle slot 310A is arranged in an arc shape. The first connecting plate 312 can increase the connection area between the first connecting portions 3111 and the bottom plate 110, thereby improving the stability of the connection between the two first sub-buckles 311 and the bottom plate 110. The top of the first connecting plate 312 forms the slot bottom wall of the first buckle slot 310A, which simplifies the manufacturing process of the first buckle slot 310A and also facilitates the arrangement of the slot bottom wall of the first buckle slot 310A in an arc shape. When the electric wire is pressed into the first buckle slot 310A, the arc-shaped slot bottom wall can provide uniform support to avoid damage to the electric wire.

[0053] Further, referring to Figure 4 The first clamping portion 3112 has a first guide surface 3113 formed on the top surface thereof facing away from the bottom plate 110. The first guide surface 3113 is arranged downwardly inclined in the direction close to the opening. The first guide surface 3113 can make the electric wire more smoothly enter the first buckle slot 310A when inserted, saving installation time and reducing the risk of damage to the electric wire or the first wire buckle 310 due to improper operation.

[0054] In some embodiments, referring to Figure 4The second wire buckle 320 comprises a second hook portion 321 and a limiting portion 322 which are arranged at intervals, and the limiting portion 322 and the second hook portion 321 jointly define a second buckle wire groove 320A; wherein the second hook portion 321 comprises a connecting segment 3211 and a hook segment 3212 which are connected, the connecting segment 3211 is connected with the bottom plate 110 and / or the second groove wall 122, and the limiting portion 322 is connected with the bottom plate 110 and / or the second groove wall 122. The connecting relationship between the second hook portion 321 and the limiting portion 322 and the bottom plate 110 and the surrounding plate 120 can be arranged as required, and the application does not limit this. For example, the connecting segment 3211 is connected with the bottom plate 110, and the limiting portion 322 is connected with the bottom plate 110.

[0055] The hook segment 3212 and the groove bottom wall of the second buckle wire groove 320A are arranged at intervals in the up-down direction, and the opening of the second buckle wire groove 320A is arranged to have an included angle with the vertical direction. In this way, the opening of the second buckle wire groove 320A is not located at the top of the second buckle wire groove 320A, and after the electric wire is buckled and fixed in the second buckle wire groove 320A, the hook segment 3212 is located above the electric wire, thereby effectively limiting the electric wire in the up-down direction and effectively preventing the electric wire from being separated from the second buckle wire groove 320A.

[0056] Further, referring to Figure 4 The limiting portion 322 is formed with a second guide surface 3221 which faces away from the top surface of the bottom plate 110 and is arranged to be inclined downward in the direction close to the opening. The hook segment 3212 is formed with a third guide surface 3213 which faces away from the top surface of the bottom plate 110 and is arranged to be inclined downward in the direction close to the opening. The second guide surface 3221 and the third guide surface 3213 can make the electric wire more smoothly enter when being inserted into the second buckle wire groove 320A, thereby saving the installation time and reducing the risk of damage to the electric wire or the second wire buckle 320 due to improper operation.

[0057] Further, referring to Figure 5 to Figure 7 The second wire buckle 320 further comprises a second connecting plate 323 which is connected to the bottom of the limiting portion 322 on both sides, the bottom of the connecting segment 3211 on both sides and the bottom plate 110, the top of the second connecting plate 323 forms the groove bottom wall of the second buckle wire groove 320A, and the groove bottom wall of the second buckle wire groove 320A is arranged in an arc shape. The second connecting plate 323 can increase the connection area of the connecting segment 3211, the limiting portion 322 and the bottom plate 110, thereby improving the stability of the connection between the two sub-buckles and the bottom plate 110. The top of the first connecting plate forms the groove bottom wall of the first buckle wire groove 310A, which simplifies the manufacturing process of the buckle wire groove and also facilitates the arrangement of the groove bottom wall of the first buckle wire groove 310A in an arc shape. When the electric wire is pressed into the first buckle wire groove 310A, the arc-shaped groove bottom wall can provide uniform support to avoid damage to the electric wire.

[0058] The first side plate 121 is provided with a wire slot 120a which communicates the electric control box mounting area 10A and the mounting groove 10B. The embodiments of the present application further comprise a wire buckle 400 which is connected with the first side plate 121 and arranged in the wire slot 120a. In some embodiments, as shown in Figure 8 , the number of the wire slots 120a is two and they are arranged at intervals. Among them, the two wire slots 120a can be respectively close to the two ends of the length direction of the first side plate 121, and one wire slot 120a is provided with a wire buckle 400. For the electric control box 200 with large volume, the strong current wire 210 and the weak current wire 220 can be led out from positions far apart. The present application can adapt to the positions where the strong current wire 210 and the weak current wire 220 are led out by arranging the wire slots 120a at the two ends of the first side plate 121, so that the interval between the strong current wire 210 and the weak current wire 220 is larger, which can more effectively reduce electromagnetic interference and improve the stability and safety of the electrical system. In addition, each wire slot 120a is equipped with a wire buckle 400, which can be used to fix the wire and prevent the wire from coming off the wire slot 120a.

[0059] Of course, the two wire slots 120a can also be arranged relatively in the middle of the length direction of the first side plate 121. The independent form of the two wire slots 120a can effectively separate the strong current wire 210 and the weak current wire 220, so the present application does not limit the specific position of the two wire slots 120a.

[0060] In some embodiments, as shown in Figure 8 , the present application further comprises a limiting piece 500, and the bottom plate 110 or the first side plate 121 is provided with a positioning part, and the limiting piece 500 is detachably connected to the positioning part to adjust the size of the electric control box mounting area 10A. The positioning part can be in the form of a boss, a groove, etc., and the limiting piece 500 is provided with a corresponding boss or groove. The positioning part can also be in the form of a threaded hole, a buckle, a slot or other forms of connecting structure, and the limiting piece 500 is fixed to the positioning part by screws, buckles or other connecting methods. It can not only realize detachable connection, but also realize positioning.
