[0039] Example 1

[0040] See Figures 1 to 6As shown, the dishwasher base provided in this application can be used in a dishwasher and can be installed at the bottom of the dishwasher. The dishwasher base includes a base 101 and an electronic control device. The base 101 supports the inner tub and provides space to house the electronic control device without occupying assembly space for other components. The base 101 includes a frame 102 and a base plate 103 connected to each other. The base plate 103 is detachably installed on the frame 102, facilitating subsequent removal from below for dishwasher maintenance.

[0041] The electrical control device provided in this application includes an electrical control module 104 and a ballast module 105. A power cord port 106 is provided in the frame 102 of the base 101. The electrical control module 104 and the ballast module 105 are installed inside the frame 102, and the high-voltage power cable harness 113 of the electrical control module 104 and the high-voltage power cable harness of the ballast module 105 are both connected to the power cord port 106. The ballast module 105 can stabilize the current and protect other electronic components, thereby making the circuit operation more stable and reliable.

[0042] Furthermore, the control module 104 and the ballast module 105 are located on opposite sides of the power line port 106, and are adjacent to the power line port 106. When connecting the control module 104 and the ballast module 105 to the power line, this layout minimizes the length of the high-voltage power harness directly connecting them, and avoids mutual interference. The shorter length of the high-voltage power harness reduces the risk of damage and malfunction, lowers material costs, simplifies installation, and improves transmission efficiency.

[0043] In an optional embodiment, the electronic control module 104 is fitted and connected to the inner side of the first side wall 107 of the frame 102, and the ballast module 105 is fitted and connected to the inner side of the second side wall 108 of the frame 102; the first side wall 107 is connected to the second side wall 108, and the power cord port 106 is close to the connection between the first side wall 107 and the second side wall 108.

[0044] In this embodiment, such as Figures 1 to 3As shown, the frame 102 is rectangular, with the power cord port 106 located near one corner of the frame 102, formed by the connection of the first sidewall 107 and the second sidewall 108. On the left and right sides of the power cord port 106, the electronic control module 104 is mounted on the first sidewall 107 on the right side of the power cord port 106, and the electronic control module 104 abuts against the inner surface of the first sidewall 107 to minimize space occupation and avoid affecting the assembly of other components. The ballast module 105 is mounted on the second sidewall 108 on the left side of the power cord port 106, and the ballast module 105 abuts against the inner surface of the second sidewall 108 to minimize space occupation and avoid affecting the assembly of other components. The electronic control module 104 and the ballast module 105 are connected to the power cord port 106 from two different directions, which avoids mutual interference between their wiring harnesses and makes the overall wiring arrangement more reasonable and neat.

[0045] In an optional embodiment, the electrical control module 104 includes an electrical control box 109 and an electrical control board 110. The electrical control box 109 is connected to the frame 102 and has a receiving cavity. The electrical control board 110 is vertically mounted in the receiving cavity, and the electrical control box 109 is used to protect the electrical control board 110. The electrical control box 109 has a first cable outlet 111 and a second cable outlet 112 at its two ends along its length. A high-voltage cable harness 113 connected to the electrical control board 110 is led out from the first cable outlet 111, and a low-voltage cable harness 114 connected to the electrical control board 110 is led out from the second cable outlet 112. This allows for the separation of high-voltage and low-voltage cables in the wiring harness of the electrical control board 110, thus avoiding interference issues.

[0046] In addition, the first outlet 111 is close to the power cord port 106 so that the high-voltage wire harness 113 leading out from the first outlet 111 can be connected to the power cord port 106 nearby. This can further shorten the length of the high-voltage wire harness 113, reduce the risk of wire harness damage and failure, and reduce the cost of wire harness raw materials. It is also beneficial to simplify line installation and improve transmission efficiency.

[0047] In an optional embodiment, the control box 109 is provided with a connecting ear 115, and a fixing part is provided on the frame 102. The top surface of the connecting ear 115 is fitted and connected to the bottom surface of the fixing part so that the control box 109 can be installed on the frame 102 from below. The fixing part is provided with a positioning member to position the control box 109.

[0048] In this embodiment, such as Figure 3As shown, the electrical control box 109 has connecting ears 115 at both ends along its length, and the bottom surface of the connecting ears 115 is flush with the ground surface of the electrical control box 109. The fixing part includes two connecting blocks 116 corresponding to the positions of the connecting ears 115. Connecting holes are correspondingly opened between the connecting ears 115 and the connecting blocks 116, and the two can be connected by bolts to achieve the installation and fixing of the electrical control box 109. Each connecting block 116 is provided with a positioning protrusion 117 to position the electrical control box 109.

[0049] When connecting the connecting ear 115 and the connecting block 116, the control box 109 is assembled from below the frame 102 so that the top surface of the connecting ear 115 fits against the bottom surface of the fixing part. During dishwasher maintenance, the base plate 103 of the base 101 is removed from the bottom to expose the internal components. When disassembling the control box 109, it can be removed from below by loosening the bolts, making maintenance and disassembly easier.

[0050] In an optional embodiment, the bottom of the electrical control box 109 is provided with a support part, which is supported on the base plate 103.

[0051] In this embodiment, since the control box 109 is connected to the frame 102 via two connecting ears 115, there is a lack of supporting structure in the middle of the control box 109. Therefore, the middle of the control box 109 is prone to deformation during dishwasher transportation or in the event of a drop. Figures 3 to 6 As shown, the present application provides a support part at the bottom of the electrical control box 109. The support part includes two support plates 118 spaced apart. When the electrical control box 109 is connected to the frame 102, the support plates 118 can rest on the bottom plate 103 below to support the electrical control box 109.

[0052] In an optional embodiment, the electrical control box 109 includes a box body 119 and a cover 120. The cover 120 is fastened to the opening of the box body 119 to form a receiving cavity. The box body 119 and the cover 120 are connected by snap-fit, making it easier to assemble and disassemble the box body 119 and the cover 120, thereby facilitating the installation and maintenance of the internal electrical control board 110. The box body 119 is provided with a first mounting part 121 to fix the electrical control board 110. Optionally, the box body 119 is provided with multiple snap-fits to fix the electrical control board 110, making it easier to assemble and disassemble the electrical control board 110.

[0053] In an optional embodiment, the electrical control box 119 is provided with a second mounting part to fix the starter 122 and ballast 123 of the ballast module 105.

[0054] In this embodiment, the change in the dishwasher's function leads to a change in the size of the control board 110, making it impossible to place the control board 110 inside the control box 109 installed on the first side wall 107. In this case, the positions of the control module 104 and the ballast module 105 need to be swapped. Since there is a difference in size between the control box 109 and the ballast box 123 of the ballast module 105, directly swapping the control box 109 and the ballast box 123 requires modifying the frame 102 structure to achieve secure installation of both. Therefore, this application provides a second mounting part in the control box 119 to fix the starter 122 and ballast 123 of the ballast module 105. When the positions of the control module 104 and the ballast module 105 are interchanged, the starter 122 and ballast 123 can be directly installed in the control box 109, which improves the versatility of the control box 119. There is no need to separately manufacture a protective box to accommodate the starter 122 and ballast 123, and there is no need to change the structure of the frame 102.

[0055] like Figure 4 As shown, the second mounting section includes a starter mounting structure 124 and a ballast mounting structure 125. The starter mounting structure 124 includes two mounting holes formed at the bottom of the electrical control box 119, through which the starter 122 can be connected to the mounting holes with bolts. Since the mounting surface of the ballast 123 is relatively wide, the bottom wall of the electrical control box 119 is relatively narrow, but the side walls of the electrical control box 119 are relatively high, the ballast 123 is mounted on the side wall of the electrical control box 119. Specifically, the ballast mounting structure 125 includes two mounting posts provided on the side of the electrical control box 119, each mounting post having threaded holes, through which the ballast 123 can be connected with bolts.

[0056] Example 2

[0057] The dishwasher base in this second embodiment is an improvement on the above embodiments. The technical content disclosed in the above embodiments will not be described again, and the content disclosed in the above embodiments also belongs to the content disclosed in this second embodiment.

[0058] See Figure 4 As shown, in an optional embodiment, the electrical control box cover 120 includes a cover body 126 and a baffle 127; the opening of the electrical control box body 119 faces the inside of the frame 102, and the cover body 126 is fastened to the opening; the baffle 127 is connected to the cover body 126, and the baffle 127 covers the top of the cover body 126.

[0059] In this embodiment, the upper part of the frame 102 is provided with components such as an inner liner, which occupies the upper space of the electrical control box 109. When disassembling and repairing the electrical control box 109, the opening of the electrical control box 119 faces the inside of the frame 102, so that maintenance personnel can more easily remove the electrical control board 110 inside the electrical control box 119. However, this structure also brings certain problems, namely, when the electrical control box cover 120 is mated with the electrical control box 119, a seam is formed between the electrical control box cover 120 and the electrical control box 119 at the top of the electrical control box 109. To prevent water from overflowing from the inner tank and dripping into the electrical control box 109 and seeping into the interior through the seams, this application provides an electrical control box cover 120 including a cover body 126 and a baffle 127. The cover body 126 is connected to the electrical control box body 119, and the baffle 127 covers the top of the cover body 126, which can prevent dripping water from seeping into the interior of the electrical control box 109 through the seams, thereby preventing malfunctions.

[0060] In an optional embodiment, the baffle 127 is provided with reinforcing protrusions 128 to enhance the strength of the baffle 127, and the circumferential direction of the reinforcing protrusions 128 forms a flow guiding structure 129. For example... Figure 4 As shown, the baffle 127 is provided with multiple reinforcing protrusions 128. The outward protrusions of the reinforcing protrusions 128 form a high-level area on the baffle 127, while the remaining parts form a low-level guiding channel on the baffle 127. When water droplets in the inner liner fall onto the baffle 127, they can converge into the guiding channel. The baffle 127 is provided with a circumferential edge 130, and the edge 130 has a drain port 131 that communicates with the guiding structure 129. Optionally, the baffle 127 is inclined, and the drain port 131 is located at the low end of the baffle 127, so that the water that converges into the guiding channel flows to the drain port 131 for discharge, avoiding the problem of water flowing to other positions and causing short circuits in live components.
