The vertical beams 113 are provided with a structure that both increases the structural strength of the vertical beams and stabilizes the structure of the vertical beams 113 after assembly with the housing 12, see fig. 27. After the vertical beam 113 is assembled with the shell 12, two sides of the inward bulge on the vertical beam 113 are simultaneously contacted with the shell 12, so that the overall strength after assembly is increased.

Referring to fig. 27-28, another embodiment of the framework 11 is illustrated, and the main difference from the framework is the upper frame structure, and other structures can adopt the framework structure. The base platform of the framework 11 has the same structure as described above, and has a front bottom beam 1121 and a rear bottom beam 1122 which are parallel to each other, and a left bottom beam 1123, a middle bottom beam 1120, and a right bottom beam 1124 which are parallel to each other; the area enclosed by the front bottom beam 1121, the rear bottom beam 1122, the left bottom beam 1123, and the middle bottom beam 1120 is a large square area where the first washing zone is located, and the area enclosed by the rear bottom beam 1122, the middle bottom beam 1120, and the right bottom beam 1124 is a small square area where the second washing zone 5 is located. The front bottom beam 1121 and the right bottom beam 1124 extend towards each other to form a front bottom extension beam 1125 and a side bottom extension beam 1126 respectively, and an arc-shaped beam 1127 is arranged between the front bottom extension beam 1125 and the side bottom extension beam 1126; wherein the front sole extension beam 1125, the side sole extension beams 1126 and the arched beams 1127 form corner sills in the corner region. The upper frame 111 has the same structure as the base, and a corner upper beam is also provided at the right rear front portion of the upper frame 111, and the corner upper beam and the corner base beam have the same structure, thereby increasing the overall strength of the framework 1. The left side of the upper frame 111 is a large square frame where the first washing area 4 is located, and four corners of the large square frame are provided with first hanging structures with the same structures as those described above. Four corners of the right rear square region of the upper frame 111 are provided with second hanging structures 115, and because the washing capacity of the second automatic washing system is small, the hanging force applied to the second hanging structures 115 is also small, so that the second hanging structures 115 are provided with hanging lugs 1117 arranged in the vertical direction, and through holes are formed in the hanging lugs.
