[0024] The mounting structure 2 includes a bracket 201 and a straight plate 202. The inner sides of the multiple brackets 201 are respectively fixed to the top of the left and right sides of the inverter 6. The inner walls of the brackets 201 are rotatably connected to the outer walls of the straight plates 202. The straight plates 202 are rotated by the pins on the inner walls of the brackets 201. The outer side of the straight plates 202 is fixed to a square plate 203. The inner wall of the square plate 203 is threadedly connected to a first bolt 204. The first bolt 204 is rotated up and down by the inner wall of the square plate 203 under force.

[0025] The inverter 6 and the top of the square plate 203 in the installation structure 2 are fitted with the connection between the dishwasher, and then the first bolt 204 is threaded through the square plate 203 from bottom to top to fix it to the dishwasher. When the inverter 6 is installed with a conflict, the square plate 203 on either side can be rotated upward on the inner wall of the bracket 201 in conjunction with the straight plate 202, and then the outer wall of the rotated square plate 203 is fitted with the inner wall of the dishwasher. Subsequently, the first bolt 204 is threaded through the square plate 203 and fixed to the dishwasher, ensuring the normal installation of the inverter for the dishwasher and the normal use of the inverter for the dishwasher.

[0026] The inner walls of the plurality of curved plates 4 are respectively threadedly connected with second bolts 5, and the rear ends of the outer walls of the plurality of second bolts 5 are all threadedly connected with the front face of the frequency converter 6. The control structure 3 includes a first clamping plate 301 and a screw 302. The top of the first clamping plate 301 fits with the bottom of the second clamping plate 7. The outer side of the top of the first clamping plate 301 is rotatably connected with the bottom of the outer wall of the screw 302. The bottom of the outer wall of the screw 302 is subjected to force to rotate through the outer bearing of the top of the first clamping plate 301. The top of the screw 302 is fixed with The handle 303 is convenient for driving the screw 302 to rotate. A round rod 304 is fixed to the left side of the top of the first clamping plate 301. The outer wall of the round rod 304 is slidably connected to the inner round opening of the top of the second clamping plate 7. The round rod 304 is forced to slide up and down through the inner round opening of the top of the second clamping plate 7. The outer wall of the screw 302 is threadedly connected to the outer round opening of the top of the second clamping plate 7. The screw 302 is forced to rotate up and down through the outer round opening of the top of the second clamping plate 7. The bottom of the inverter 6 is fixed with multiple vertical cylinders 9 ， The inner wall of the vertical tube 9 is threadedly connected to the vertical rod 10, and the inner wall of the vertical tube 9 and the outer wall of the vertical rod 10 are both processed with threads. The vertical rod 10 can conduct the heat generated by the internal components of the inverter 6 through its own copper material. The bottom of the left and right sides of the vertical rod 10 are respectively fixed with horizontal plates 11, which facilitate the rotation of the vertical rod 10.

[0027] Working principle:

[0028] Dishwasher inverter installation:

[0029] First, place the mesh plate 1 in front of the front notch of the inverter 6. At this time, the rear of the curved plate 4 on the outer wall of the mesh plate 1 is in contact with the front of the inverter 6. Then, the second bolt 5 is threaded from the right front to the rear to pass through the curved plate 4 and is fixed to the inverter 6. Then, the inverter 6 and the top of the square plate 203 are in contact with the connection between the dishwasher and the first bolt 204 is threaded from bottom to top to pass through the square plate 203 and fixed to the dishwasher. When the inverter 6 is installed in a conflicting manner, the square plate 203 on either side can be rotated upward on the inner wall of the bracket 201 in conjunction with the straight plate 202. Then, the outer wall of the rotated square plate 203 is in contact with the inner wall of the dishwasher. Then, the first bolt 204 is threaded through the square plate 203 and is fixed to the dishwasher.

[0030] Dishwasher inverter connection:

[0031] After the inverter 6 is installed, the wire is electrically connected to the connection on the front of the inverter 6. Then the handle 303 drives the screw 302 through the second clamping plate 7. The screw 302 that rotates downward drives the first clamping plate 301 downward, so that the first clamping plate 301 is separated from the second clamping plate 7. Then the other end of the wire is passed through the two clamping plates 7. Then the handle 303 drives the screw 302 to rotate in the opposite direction, so that the screw 302 drives the first clamping plate 301 to move upward and cooperate with the second clamping plate 7 to tighten the wire. Then the other end of the wire is connected to the motor box inside the dishwasher.

[0032] Dishwasher inverter heat dissipation:

[0033] Working in conjunction with the horizontal plate 11, the vertical rod 10 rotates upward on the inner wall of the vertical tube 9, aligning with the outer thread. This allows the vertical rod 10 to penetrate the top of the inverter and mate with the components on the inner wall of the inverter 6. The copper material of the vertical rod 10 then dissipates heat generated by the components. The front of the inverter is equipped with a screen 1 for heat dissipation. The vertical rod 10 further improves heat dissipation efficiency, especially when the screen 1 is blocked. The height of the vertical rod is adjustable, as long as the upper end rests on the components within the inverter, making it suitable for various inverter components.

[0034] Example 2:

[0035] See also Figure 1-6 In this embodiment, a frequency converter for a dishwasher further includes a bottom plate 8 , wherein the inner sides of the two bottom plates 8 are respectively fixedly connected to the left and right bottoms of the frequency converter 6 .

[0036] Working principle:

[0037] When the square plate 203 is installed in an upwardly rotated manner, the outer wall of the bottom plate 8 will fit against the inner wall of the dishwasher, and the bottom plate 8 will support and abut the side where the inverter 6 is installed to prevent the inverter 6 from rotating downward due to gravity.
