1. An outer tub applied to a laundry treating apparatus, the outer tub comprising:

an outer cylinder body, wherein one end of the outer cylinder body is provided with a first opening;

the diameter-expanding cylinder is characterized in that one end of the diameter-expanding cylinder is connected with the opening end of the outer cylinder body, the other end of the diameter-expanding cylinder is provided with a second opening, and the area of the second opening is larger than that of the first opening.

2. The outer cylinder according to claim 1, wherein the diameter-enlarging cylinder comprises a conical cylinder section and a straight cylinder section, a small diameter end of the conical cylinder section is connected with the opening end of the outer cylinder body, a large diameter end of the conical cylinder section is connected with one end of the straight cylinder section, and a port of the other end of the straight cylinder section forms the second opening.

3. The outer barrel of claim 1, wherein an outer barrel reinforcing structure is provided at an interface area of the outer barrel body and the enlarged diameter barrel.

4. The outer tub as claimed in claim 3, wherein the outer tub reinforcing structure includes a plurality of first reinforcing ribs arranged at intervals along a circumferential direction of the outer tub, each of the first reinforcing ribs extending in an axial direction of the outer tub.

5. The outer barrel of claim 4, wherein one end of the first stiffener is located in the middle of the conical barrel section of the expanded diameter barrel, and the other end of the first stiffener extends to the end of the outer barrel body facing away from the first opening.

6. The outer tub as claimed in claim 3, wherein the outer tub reinforcing structure includes a second reinforcing rib provided on an outer wall of the outer tub body, the second reinforcing rib having a ring shape and extending in a circumferential direction of the outer tub body.

7. A cartridge assembly comprising the outer cartridge of any one of claims 1 to 6, the cartridge assembly further comprising an inner cartridge disposed within the outer cartridge and a dock seal mounted at the second opening of the outer cartridge.

8. The cartridge assembly of claim 7, wherein the inner cartridge comprises an inner cartridge body and an inner cartridge reinforcing structure disposed at an end of the inner cartridge body proximate the second opening, the inner cartridge reinforcing structure having an outer diameter greater than an outer diameter of the inner cartridge body, the inner cartridge reinforcing structure being disposed within the expanded diameter cartridge.

9. The cartridge assembly of claim 8, wherein a first predetermined distance is provided between the outer wall of the inner barrel reinforcement structure and the inner wall of the straight barrel section of the expanded diameter barrel, the first predetermined distance being 4% -10% of the diameter of the straight barrel section.

10. A drum assembly according to any one of claims 7 to 9, wherein the outer port of the door seal forms a laundry access opening having a diameter equal to the inner diameter of the inner drum.

11. The cartridge assembly of any one of claims 7 to 9, wherein an end of the inner barrel proximate the second opening is a second predetermined distance from the door seal, the second predetermined distance being 15% -25% of an axial length of the expanded diameter cartridge.

12. The cartridge assembly of any one of claims 7 to 9, further comprising a pressure ring coupled to the outer barrel to compress the dock seal between the pressure ring and the outer barrel.

13. A laundry treatment apparatus comprising a cartridge assembly as claimed in any one of claims 7 to 12.
