In the absence of further limitations, an element defined by the phrase "comprises a..." does not exclude the presence of other identical elements in the product or system comprising the element.

[0063] In the existing technology, multi-drum washing machines can only realize single-drum washing and single-drum washing and drying, with a single drying mode, which cannot meet different drying needs.

[0079] In order to solve the problem of loose sealing when the air inlet baffle 31 closes the first main air inlet duct outlet 231 and the second main air inlet duct outlet 232, the present embodiment proposes that the air inlet baffle 31 can slide along the radial direction of the rotating shaft of the air inlet baffle 31; when the air inlet baffle 31 closes the first main air inlet duct outlet 231 or the second main air inlet duct outlet 232, the air inlet baffle 31 is sealed and connected to the side wall of the main air inlet duct 23; when the air inlet baffle 31 opens the first main air inlet duct outlet 231 or the second main air inlet duct outlet 232, the air inlet baffle 31 is spaced apart from the side wall of the main air inlet duct 23; the flow area of ​​the air inlet baffle 31 is greater than the flow area of ​​any main air inlet duct outlet; the air inlet baffle 31 can completely block the first main air inlet duct outlet 231 or the second main air inlet duct outlet 232;

[0080] Furthermore, a first sealing ring is provided at the first main air inlet duct outlet 231 and the second main air inlet duct outlet 232. The first sealing ring is located in the main air inlet duct 23 and protrudes from the inner wall of the main air inlet duct 23. The first sealing ring is made of rubber material.

[0081] The air inlet baffle 31 is slidably disposed on the first radial frame 322 , and a first elastic member 36 is disposed between the air inlet baffle 31 and the first radial frame 322 ;

[0082] When the air inlet baffle 31 closes the first main air inlet duct outlet 231 or the second main air inlet duct outlet 232, under the action of the first elastic member 36, the air inlet baffle 31 abuts against the first sealing ring; the first main air inlet duct outlet 231 or the second main air inlet duct outlet 232 is tightly sealed to reduce air leakage, so that the drying air in the main air inlet duct 23 flows smoothly to the first main air inlet duct outlet 231 and the second main air inlet duct outlet 232; when the air inlet baffle 31 opens the first main air inlet duct outlet 231 or the second main air inlet duct outlet 232, under the action of the first elastic member 36, the drying air in the main air inlet duct 23 flows smoothly to the first main air inlet duct outlet 231 and the second main air inlet duct outlet 232. The air inlet baffle 31 is separated from the side wall of the main air inlet duct 23, so that the air inlet baffle 31 can rotate smoothly, reducing the friction between the air inlet baffle 31 and the inner wall of the main air inlet duct 23, reducing the torque of the first drive motor 33, and reducing the abnormal noise caused by friction; Specifically, a first sliding hole is formed at one end of the first radial frame 322 close to the air inlet baffle 31, and a first sliding rod is provided on the side of the air inlet baffle 31 close to the first radial frame 322. The first sliding rod is slidably disposed in the first sliding hole, and a first elastic member 36 is provided between the first sliding rod and the bottom wall of the first sliding hole;

[0083] In other embodiments, along the rotation direction of the air inlet baffle 31, the radial thickness of the air inlet baffle 31 gradually decreases, and the radial thickness of the first sealing ring gradually increases;

[0084] When the air inlet baffle 31 rotates and approaches the first main air inlet duct outlet 231 or the second main air inlet duct outlet 232, the air inlet baffle 31 cooperates with the first sealing ring and the air inlet baffle 31 abuts against the first sealing ring; when the air inlet baffle 31 rotates and moves away from the first main air inlet duct outlet 231 or the second main air inlet duct outlet 232, the air inlet baffle 31 separates from the first sealing ring and the air inlet baffle 31 is spaced apart from the side wall of the main air inlet duct 23.

[0085] To address the problem that when the air inlet baffle 31 blocks the first main air inlet duct outlet 231, the dry air flow in the main air inlet duct 23 cannot flow smoothly to the second main air inlet duct outlet 232, or when the air inlet baffle 31 blocks the second main air inlet duct outlet 232, the dry air flow in the main air inlet duct 23 cannot flow smoothly to the first main air inlet duct outlet 231, this embodiment proposes that first blocking ribs are provided at the first main air inlet duct outlet 231 and the second main air inlet duct outlet 232;

[0086] When the air inlet baffle 31 closes the first main air inlet duct outlet 231 or the second main air inlet duct outlet 232, the first baffle rib can close the gap between the air inlet baffle 31 and the side wall of the main air inlet duct 23, thereby playing a wind-blocking role, reducing the flow of drying air into the gap between the air inlet baffle 31 and the side wall of the main air inlet duct 23, improving the sealing performance of the air inlet baffle 31, and allowing the drying air to flow toward the main air inlet duct outlet in an open state, thereby improving the drying efficiency.

[0087] In order to address the problem of low drying efficiency caused by the low temperature of the drying airflow, this embodiment proposes that a heater is provided in the main air inlet duct 23. Preferably, the heater is a PTC heater. During the drying stage, the PTC heater can heat the drying airflow, so that the drying airflow has a higher temperature, plays an auxiliary heating role, and improves the drying efficiency.
