[0002] As people's living standards continue to improve, their quality of life is also constantly improving, and the requirements for washing machine functions are also increasing. When washing clothes, users require the ability to wash them separately, such as washing underwear and outerwear separately, washing clothes of different materials separately, washing baby clothes separately, washing clothes of different degrees of dirtiness separately, washing clothes of different colors separately, etc. Therefore, multi-barrel washing machines are increasingly used in the market. However, the connection between multiple washing machine barrels is either separate or multiple separate barrels are connected together through some structural rigidity, which is a relatively simple form. Considering the relatively complex structure of the barrel bottom, if the barrel bottom is made into an integrated structure, it will increase the difficulty of the barrel bottom mold and the injection molding cycle. Therefore, it is necessary to design a multi-barrel barrel cover structure with an integrated barrel cover to overcome the above defects. Summary of the Invention

[0013] (2) The front is connected and fastened by an integrated barrel cover, the top is connected by an upper balance block, the rear connecting plate is fixed, and the bottom is fixed by a lower balance block, which can achieve connection in four directions of front, back, top and bottom, with high connection strength;

[0014] (3) The barrel cover is integrally formed, which is easy to process and low in cost;

[0015] (4) The safety distance between the two barrels is reduced, and the safety distance from the frame is increased, which facilitates the placement of the circuits and waterways of the entire machine;

[0016] (5) The two washing machine drums are compactly combined to reduce the size of the entire machine, which can save materials and adapt to more user scenarios. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be understood that the following specific embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention.

[0025] As shown in the figure, the integrated drum cover structure of a double-drum washing machine described in the present invention includes two limit covers 1 combined into an integrated whole and a reinforced connection structure 2. The two limit covers 1 are hollow cylindrical, and the edge of the rear end surface of the limit cover is provided with an outwardly protruding convex edge 4. The convex edge 4 is provided with a connecting hole 5 and an upper shock absorber mounting seat 6. The reinforced connection structure 2 is arranged between the two limit covers 1. The upper and lower surfaces of the reinforced connection structure 2 are provided with balance block mounting seats 7, and the outer sides of the two limit covers are provided with lower shock absorber mounting seats 8.

[0026] The following example is a horizontal side-by-side integrated barrel cover structure, such as Figure 5 As shown, when in use, the two limit covers 1 of the integrated barrel cover structure are fixed to the bottom of the barrel through the connecting hole 5, the upper shock absorber mounting seat 6 is connected to the suspension spring, the lower shock absorber mounting seat 8 is connected to the lower shock absorber 14, the rear connecting plates of the two barrels are fixed, the upper part is connected by the upper balancing block 15, and the lower part is fixed by the lower balancing block 16. The connection in four directions ensures the connection strength.

[0027] The integrated barrel cover structure described in the present invention can also be expanded to vertical scenarios.

[0028] One (or two) upper shock absorber mounting seats 6 may be provided on the upper side of each limiting cover 1 , and one (or two) lower shock absorber mounting seats 8 may be provided on the lower side.

[0029] A sealing groove 9 is provided at the rear end of the convex edge 4. When the integrated bucket cover structure is connected to the washing bucket, a sealing ring is provided in the sealing groove 9 to prevent water leakage.

[0030] The front end surface of the limiting cover 1 of the present invention is retracted inward to form a door seal installation protruding surface 3 for installing the door seal 13.

[0031] A drainage hole 10 is provided on the door seal mounting protruding surface 3 to reduce water residue in the door seal 13 during drainage.

[0032] In addition, an installation limiting groove 11 is provided on the inner side of the door seal installation protruding surface 3 to facilitate the rapid installation of the door seal 13.

[0033] The tub cover of the present invention is an integrated plastic structure, and the middle reinforced connecting structure, the balance block and the rear reinforcing plate form a whole. It can not only reduce the mutual influence of the two tubs during dehydration, but also reduce the arrangement of shock absorbers, save costs, and bring great convenience to the assembly of the washing machine. When working, the two washing tubs run at the same time, and there will be a situation where they move inward or twist back and forth at the same time. The present invention uses shock absorbers above and below the washing tubs to reduce the amplitude of the left and right twisting of the tubs. In this way, the two washing tubs are rigidly connected together, the safety distance between the two tubs can be reduced, and the safety distance from the frame can be increased, which is convenient for the placement of the circuits and water channels of the whole machine, saves space, and has good integrity.

[0034] The center of the balancing weight mounting seat 7 of the present invention is provided with a screw hole 12, and when installing, the balancing weight is placed on it and the bolts are screwed on to fix it.

[0035] It should be noted that the above content merely illustrates the technical idea of ​​the present invention and cannot be used to limit the scope of protection of the present invention. For ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications all fall within the scope of protection of the claims of the present invention.
