With the improvement of living standard of people, the nursing requirements of people on clothes are no longer limited to two words, and more attention is paid to the flatness, dryness and line neatness of clothes. Especially under the influence of epidemic situations, people pay more and more attention to the sanitary and safety conditions of clothes. Accordingly, the laundry care machine is produced. A conventional laundry care machine includes a swing device, a drying device, an air guide device, a steam device, and the like. The internal environment of the nursing machine keeps certain temperature and humidity through the drying device and the steam device, and then the swinging device prompts the clothes to turn or swing continuously, so as to realize drying and wrinkle removal of the clothes. The traditional clothes nursing machine mostly adopts a heat pump as a drying heat source, and the heat pump works and is heated slowly, so that the drying time is long, and the user experience is influenced. In addition, the existing clothes nursing machine mostly adopts a crank-connecting rod structure as a swinging device, the swinging amplitude of the structure in the working process is small, the clothes are not fully contacted with the ambient air, and the shaking and scattering effect is poor, so that the nursing time is long, and the wrinkle removing effect is poor. Meanwhile, the swinging device with the structure has a quick return characteristic, larger noise exists in the working process, and the stability and the service life of the machine body are influenced.

To this end, the prior art is further improving upon laundry care machines. For example, chinese utility model patent application CN213804502U discloses a clothes care machine. The clothes care machine comprises a cabinet body, a driving piece and a turntable assembly, wherein the turntable assembly comprises a plurality of mutually linked turntables. During operation, the clothes nursing machine drives at least one rotary table to rotate through the driving part, and then drives the plurality of rotary tables to rotate in a reciprocating mode along a preset angle, and bidirectional rotary swing of clothes is achieved. The clothes care machine also comprises a humidifying system, a heat circulating system, a water collecting tank and other structures, and is used for providing a proper temperature and humidity environment for clothes. The clothes care machine can reduce working noise to a certain extent. However, the clothes have large twisting force and small swinging amplitude in the nursing process, and the wrinkle removing effect is still not ideal. Meanwhile, the drying efficiency of the laundry is not improved. Therefore, there is an improvement in this solution.

Accordingly, there is a need in the art for a new solution to the above technical problems.

When the clothes are to be cared, the clothes to be cared are hung in the hanging groove 241 by a hanger, a hook, or the like. The driving device 21 drives the hanging ring 24 and the clothes to move through the driven seat 22 and the connecting arm 23, and the clothes can swing greatly and can be in full contact with air under the action of centrifugal force. In one or more embodiments, the drive device 21 maintains a single rotation in a clockwise or counterclockwise direction, which motion eliminates the snap-back feature and makes the operation less noisy. Alternatively, the driving device 21 can be rotated in both clockwise and counterclockwise directions to further increase the swing amplitude of the laundry, improving the wrinkle and bacteria removing effect. In one or more embodiments, the drive 21 maintains a constant speed of rotation. Alternatively, the drive means 21 may be rotated at repeatedly increasing and decreasing speeds within a certain speed range. In one or more embodiments, the rotation speed of the driving device 21 is positively correlated to the weight of the clothes to be treated. In one or more embodiments, the rotation speed of the driving device 21 is adaptively adjusted according to the material of the laundry.

As shown in fig. 1, one end of the air duct 33 communicates with the air outlet of the fan 32, and the other end is fixed to the electric heating unit 31. In one or more embodiments, the air duct 33 forms a relatively independent air path between the fan 32 and the electric heating unit 31, so that the wind of the fan 32 can pass through the electric heating unit 31 more intensively.

When drying, the fan 32 makes the air flow intensively pass through the electric heating unit 31, and the air is heated by the electric heating unit 31 and quickly raised to a predetermined temperature, and then enters the nursing room 18 through the air inlet 1611 to raise the temperature in the nursing room 18. The hot air is blown upward from below the care room 18. Since the clothes are rotated around the rotation axis by the hanging ring 24, the clothes form a hollow circular table during the rotation, and the hot air can pass through the lower part of the hollow circular table and fully contact with the clothes, thereby drying the moisture on the clothes and caring the clothes more efficiently. Thereafter, the airflow exits the nursing chamber 18 through the return air opening 1621 and is again drawn by the fan 32. The direction of the airflow is shown by the dashed arrows in fig. 1.

Specifically, the end of the return pipe 443 is connected to the air guide duct 33. Alternatively, the end of the return pipe 443 is connected to an air duct (not shown in the drawings) formed on or near a fan case that houses the fan 32, which is in fluid communication with the return pipe 443 and the air guide duct 33, respectively. In one or more embodiments, the water storage box 41 is detachably fitted in the equipment room 19 and is provided near the cabinet door of the cabinet 1, so that the water storage box 41 can be easily taken out from one side of the cabinet 1. Optionally, a water filling port (not shown) is provided on the water storage tank 41. In one or more embodiments, as shown in fig. 1, a waste water cartridge 43 is removably fitted in the equipment compartment 19 and disposed adjacent to the door of the cabinet 1, so that the waste water cartridge 43 can be conveniently taken out from one side of the cabinet 1. In one or more embodiments, the waste water box 43 is disposed adjacent to the return air opening 1621. Alternatively, the waste water box 43 is disposed immediately below the return air inlet 1621.

During the steam injection, in one or more embodiments, the purified water in the water storage tank 41 is delivered to the steam generator 42 through the purified water pipe 441. Optionally, the purified water in the water storage tank 41 is pumped into the steam generator 42 by a micro-pump (not shown in the figure). The steam generated by the steam generator 42 is delivered to the air path of the drying device 3 to circulate for increasing the humidity in the nursing room 18. Wastewater generated during operation of the steam generator 42 flows into the wastewater tank 43 through the wastewater pipe 442.
