In this embodiment, the outer edge of the upper plate 1 is circular. A shaft through-hole 11 for the motor shaft to pass through is opened at the central axis of the upper plate 1.

[0028] The side plate 2 is a cylindrical structure, and the shape of its outer circumference is the same as that of the outer circumference of the upper plate 1. The side plate 2 is vertically arranged, and a vertical through-hole is provided at the center of the lower plate 3. In this embodiment, the side plate 2 is in a cylindrical structure, and the side plate 2 is fixedly connected between the outer circumference of the upper plate 1 and the hole wall of the through-hole of the lower plate 3. The upper plate 1, the side plate 2, and the lower plate 3 are coaxially arranged. The top end of the side plate 2 is fixedly connected to the outer edge of the upper plate 1, and the lower edge of the side plate 2 is fixedly connected to the top edge of the through-hole of the lower plate 3.

[0029] As Figure 1 、 Figure 2 shown, the lower plate 3 includes 6 motor mounting parts 5 for fixedly mounting the motor on the washing machine. The 6 motor mounting parts 5 are evenly arranged in a circumferential array with the central axis of the shaft through-hole 11 as the center, and the motor mounting parts 5 are located on the outer peripheral side of the lower plate 3. Among them, the included angle between two adjacent motor mounting parts is 60°.

[0030] Each motor mounting part 5 of the utility model is a motor mounting support point, and a total of six motor mounting support points are set. The six motor mounting parts 5 are evenly arranged in a circular array with the central axis of the shaft through hole 11 as the center, wherein the angle between two adjacent motor mounting parts is 60°, which is equivalent to setting a motor mounting support point every 60°, effectively solving the centrifugal force generated when the dehydration barrel with a capacity of more than 8 kilograms is released, achieving the working effect of making the dehydration barrel run smoothly, extending the service life, and ensuring the safety factor during operation. The utility model provides a sufficiently high structural strength for the large-capacity dehydration barrel, ensuring the high stability of the large-capacity dehydration barrel driven by it.

[0031] like Figure 1 , Figure 2 As shown, specifically, each motor mounting portion 5 adopts an axisymmetric structure, and the central axis of each motor mounting portion 5 passes through the center of the lower plate 3, which can further improve the stability of the structure. The angle between two adjacent motor mounting portions 5 is 60°, that is, the angle between the central axes of two adjacent motor mounting portions 5 is 60°. It is ensured that a motor mounting support point is set every 60°, which effectively solves the centrifugal force generated when the dehydration bucket with a capacity of more than 8 kilograms is released, and improves the structural strength.

The corner groove portions are closer to the arc edge 61 than the main groove portion, which can further strengthen the structural strength of the support plate. Even if the thickness of the support plate is relatively thin, the combined cooperation of the first strengthening portion 53 and the second strengthening portion 63 can ensure that the support plate has sufficient structural strength.

[0035] As Figure 1 , Figure 2 shown, heat dissipation holes 7 are formed in the upper plate 1. The number of the heat dissipation holes 7 is one or more.
