[0050] The dishwasher provided by the present invention is provided with the above-mentioned control panel assembly of the dishwasher, thereby saving the assembly time of the dishwasher and reducing the installation cost.

[0051] Embodiment 1

[0052] like Figure 1 As shown, this embodiment provides a control panel assembly of a dishwasher.

[0053] The control board assembly includes a PCB box 2 and a control board body 1.

[0054] The control panel body 1 comprises a first side wall 101 and a second side wall 102 arranged in parallel, and a third side wall 103 connecting the first side wall 101 and the second side wall 102, a limiting ear 104 is arranged on the first side wall 101 and / or the second side wall 102, and a protruding clamping portion 105 is arranged on the inner surface of the third side wall 103;

[0055] The PCB box 2 has a certain extension length in a direction parallel to the first side wall 101 and the third side wall 103, and has end walls 201 at both ends of the length direction, and at least one of the end walls 201 is provided with a plug-in portion 202;

[0056] The limiting ear 104 includes a limiting portion that is arranged relative to the third side wall 103, and the plug-in portion 202 is inserted in the spacing space between the third side wall 103 and the limiting portion. The upper part and / or the lower part of the PCB board box 2 is clamped with the clamping portion 105 to fix the PCB board box 2 between the first side wall 101 and the second side wall 102.

[0057] The control panel assembly of the dishwasher provided in this embodiment comprises a control panel body and a PCB box 2. The PCB box 2 is provided with a PCB board.

[0058] The control panel body 1 includes three side walls, namely, a first side wall 101, a second side wall 102 and a third side wall 103. The first side wall 101 and the second side wall 102 are arranged in parallel, and the third side wall 103 connects the first side wall 101 and the second side wall 102. In other words, the control panel body 1 includes the first side wall 101, the third side wall 103 and the second side wall 102 connected in sequence. Among them, the first side wall 101 and the third side wall 103 are perpendicular to each other, and the second side wall 102 and the third side wall 103 are also perpendicular to each other. A limiting ear 104 is arranged on the second side wall 102, and a protruding clamping portion 105 is provided on the inner surface of the third side wall 103. Specifically, the clamping portion 105 is arranged at a position close to the second side wall 102.

[0059] The PCB board box 2 is in a long strip structure and is extended in a direction parallel to the first side wall 101 and the third side wall 103. It has end walls 201 at both ends in the length direction, and at least one of the end walls 201 is provided with a plug-in portion 202. The number of the limiting ears 104 is the same as the number of the plug-in portions 202, and the positions are correspondingly arranged. In this embodiment, a plug-in portion 202 is respectively arranged on the end walls 201 at both ends of the PCB board box 2, and two limiting ears 104 are arranged on the second side wall 102 at the corresponding position of the plug-in portion 202. During installation, the plug-in portion 202 on the PCB board box 2 is inserted into the interval between the third side wall 103 and the limiting portion, and the upper part and / or the lower part of the PCB board box 2 is engaged with the clamping portion 105, so that the PCB board box 2 is fixedly arranged between the first side wall 101 and the second side wall 102. That is to say, the PCB box 2 can be fixedly connected to the control board body by the interaction of the limiting ears 104, the clamping portion 105, and the plug-in portion 202.

[0060] In another solution of this embodiment, only one limiting ear 104 and one plug-in portion 202 may be provided to fix the control board body and the PCB box 2 together.

[0061] The solution of this embodiment also includes: the limiting ear 104 also includes a first plate-like structure 1041 perpendicular to the third side wall 103, the first plate-like structure 1041 is fixedly set on the second side wall 102, and extends toward the first side wall 101; the limiting portion is a limiting plate 1042 arranged at the extended end of the first plate-like structure 1041 and perpendicular to the first plate-like structure 1041.

[0062] like Figure 2-4 As shown, in the solution of this embodiment, the limiting ear 104 includes a first plate-like structure 1041 and a limiting portion. The first plate-like structure 1041 is perpendicular to the third side wall 103 and is arranged between the first side wall 101 and the second side wall 102. One end of the first plate-like structure 1041 is fixed on the inner surface of the second side wall 102, and the other end is perpendicular to the second side wall 102 and extends in the direction of the first side wall 101. The limiting portion is a limiting plate 1042 arranged at the extended end of the first plate-like structure 1041, and the limiting plate 1042 is perpendicular to the first plate-like structure 1041. In other words, one side of the first plate-like structure 1041 faces the third side wall 103, and the other side is away from the third side wall 103. The limiting plate 1042 is arranged at the position of the other side, and there is a gap between the limiting plate 1042 and the third side wall 103 for the plug-in portion 202 on the PCB board box 2 to be inserted. Thereby providing a limiting force for the PCB board box 2 in the direction of the third side wall 103.

[0063] In the scheme of the present embodiment, two limiting ears 104 are arranged at intervals on the second side wall 102, and the limiting plate 1042 is arranged at the extension end of the first plate-like structure 1041 toward the direction of the other limiting ear 104. In other words, the extension directions of the two limiting plates 1042 are arranged relatively. During installation, the plug-in parts 202 at the two ends are respectively inserted into the intervals between the corresponding limiting parts and the third side wall 103, so that the limiting plates 1042 and the plug-in parts 202 abut against each other to limit. It is worth noting that in the scheme provided in the present embodiment, two limiting ears 104 are a group, and the number of groups of limiting ears 104 arranged on the control board is related to the number of installed PCB board boxes 2, and the number of groups of limiting ears 104 is the same as the number of PCB board boxes 2 arranged.

[0064] In another solution of this embodiment, the limiting ear 104 is arranged on the first side wall 101 , the clamping portion 105 is arranged near the first side wall 101 , and the upper part of the PCB box 2 is clamped on the clamping portion 105 .

[0065] The solution of this embodiment also includes: the side of the first plate-like structure 1041 is fixedly connected to the third side wall 103. The first plate-like structure 1041 has two side edges, one side edge faces the third side wall 103 and is fixedly arranged with the third side wall 103, and the other side edge is away from the third side wall 103, and the limiting plate 1042 is arranged at the position of the other side edge. In this solution, since the side edge of the first plate-like structure 1041 is fixedly connected to the third side wall 103, the limiting force provided by the limiting ear 104 is more stable.

[0066] The present embodiment also includes that the plug-in portion 202 includes a second plate-like structure, one end of the second plate-like structure is connected to the end wall 201 of the PCB box 2, and the other end extends away from the end wall 201;

[0067] The surface of the limiting plate 1042 facing the third side wall 103 abuts against the second plate-shaped structure.

[0068] In the above solution, the plug-in portion 202 includes a second plate-like structure, one end of which is connected to the end wall 201 of the PCB board box 2, and the other end of which extends away from the end wall 201. During installation, the plug-in portion 202 is inserted into the gap between the limiting plate 1042 and the third side wall 103. The second plate-like structure has an inner side and an outer side, the inner side is close to the third side wall 103, and the outer side is away from the third side wall 103. The outer side of the second plate-like structure abuts against the surface of the limiting plate 1042 facing the third side wall 103 to limit the PCB board box 2.

[0069] In another solution of this embodiment, one side edge of the limiting plate 1042 abuts against the end wall 201 of the PCB box 2 .

[0070] In the above scheme, the limiting plate 1042 is a square plate-like structure with a certain thickness and has four edges. The first side edge is coplanar with the first plate-like structure 1041, the second side edge is connected to the first side edge and extends perpendicularly to the first plate-like structure 1041 toward the end wall 201, the third side edge is extended at the extended end of the second side edge parallel to the first plate-like structure 1041 toward the second side wall 102, and the fourth side edge is extended perpendicularly to the third side edge toward the first side edge at the extended end of the third side edge and connected to the first side edge. In this scheme, the second side edge of the limiting plate 1042 abuts against the end wall 201 of the PCB board box 2. Thereby increasing the limiting force.

[0071] In another solution of this embodiment, the edge of the second plate-shaped structure abuts against the inner surface of the first plate-shaped structure 1041 .

[0072] In another solution of this embodiment, one side edge of the limiting plate 1042 abuts against the end wall 201 of the PCB box 2 , and the edge of the second plate-like structure abuts against the inner surface of the first plate-like structure 1041 .

[0073] In the above solution, the limiting plate 1042 abuts against the end wall 201 , and the plug-in portion 202 also abuts against the first plate-like structure 1041 , further increasing the limiting force.

[0074] The solution of this embodiment also includes: the limiting ear 104 also includes an extension portion 106, which is perpendicular to the first plate-like structure 1041 and extends from the end of the first plate-like structure 1041 toward the end wall 201 of the PCB box 2, and its extended end abuts against the end wall 201 of the PCB box 2.

[0075] According to the above scheme, the limiting plate 1042 is a square plate-like structure having a second side edge, and the second side edge is perpendicular to the first plate-like structure 1041. In this scheme, the limiting ear 104 also has an extension portion 106, and the extension portion 106 extends perpendicularly to the first plate-like structure 1041 at the extension end of the first plate-like structure 1041 toward the end wall 201 of the PCB board box 2, and the extension end abuts against the end wall 201 of the PCB board box 2. It is worth noting that in this scheme, part of the extension portion 106 is coplanar with the second side edge of the limiting plate 1042.

[0076] In the above solution, since the extension part 106 is provided, the extension part 106 abuts against the end wall 201 of the PCB board box 2, so that the PCB board box 2 and the control board body 1 are fixed more firmly.
