That is, the clutch 5 includes a first driving shaft 51, a second driving shaft 53 and a guide passage 52, wherein the first driving shaft 51 is connected to the outer bottom wall of the inner tub 2 for driving the inner tub 2 to rotate, the second driving shaft 53 passes through the inner tub 2 and is connected to the pulsator 6 in the inner tub 2 for driving the pulsator 6 to rotate, both ends of the guide passage 52 are respectively communicated with the airflow driving part 3 and the communication hole a (for example, both ends of the guide passage 52 are respectively connected to the communication hole a and the first interface), in a condition that the laundry treating device 100 is in the washing mode, the airflow driving part 3 is operated to drive the airflow to flow to the inner tub 2, the second driving shaft 53 drives the pulsator 6 to rotate, and the rotation of the pulsator 6 can drive the water and the airflow in the inner tub 2 to be sufficiently mixed and to move in a certain direction to impact the washed laundry, thereby improving the washing effect of the laundry. It is understood that the inner tub 2 may also be rotated in the washing mode. In the dehydration mode of the laundry treating apparatus 100, the second driving shaft 53 does not drive the pulsator 6 to rotate, the first driving shaft 51 drives the inner tub 2 to rotate with respect to the outer tub 1, and the airflow driving part 3 does not operate, thereby achieving the purpose of dehydrating the laundry.

It can be understood that, the impeller 6 rotates to drive the clothes to rotate and rub with the water flow, the clothes are inevitably wound and abraded, and the problem of winding the clothes can be avoided at least to a certain extent by leading the airflow driving part 3 into the inner barrel 1, so that the abrasion of the clothes is further avoided.

Here, it should be noted that the specific structure of the clutch 5 is well known to those skilled in the art, and will not be described in detail here.

Specifically, the communication hole a faces the pulsator 6. Therefore, the air current entering into the inner barrel 2 from the communication hole a can directly enter into the space between the impeller 6 and the bottom wall of the inner barrel 2, thereby being beneficial to prolonging the stay time of the air current in the inner barrel 2, improving the washing effect and being convenient for the impeller 6 to rotate so as to ensure that the water and the air current are fully mixed to form more water air current.

Optionally, a check valve 9 is connected in series between the airflow driving member 3 and the other end of the diversion channel 52 (for example, a check valve 9 is connected in series between the airflow driving member 3 and the third port), and the check valve 9 is guided and communicated in a direction from the airflow driving member 3 to the diversion channel 52, that is, airflow can only flow from the airflow driving member 3 and the check valve 9 to the diversion channel 52, and water, steam, etc. in the inner tub 2 cannot flow from the diversion channel 52 to the airflow driving member 3, so that the reliability of the operation of the airflow driving member 3 is ensured. Of course, the present invention is not limited thereto, and in other alternative embodiments, the level of the airflow driving member 3 may be higher than the highest water level in the outer tub 1, so that the backflow of the water flow may be effectively prevented, and the reliability of the operation of the airflow driving member 3 may be improved.

In some optional embodiments of the present invention, the laundry treating apparatus 100 further comprises a heater 7, and the heater 7 is connected to the airflow driving member 3 for heating the airflow introduced into the inner tub 2. Specifically, after the laundry treating apparatus 100 completes the dehydration, i.e., in the drying mode, the airflow driving part 3 and the heater 7 are simultaneously operated, the airflow driving part 3 drives the airflow into the inner tub 2, and the heater 7 is used for heating the airflow into the inner tub 2, so that the laundry drying purpose can be achieved. It is understood that, in the washing mode of the laundry treating apparatus 100, if it is required to improve the washing effect in a cold environment in winter, the heater 7 may be used to heat the air flowing into the inner tub 2 so as to increase the temperature of the water in the inner tub 2.

Specifically, for example, the heater 7 is connected between the check valve 9 and the airflow actuator 3, so that the one-way conduction action of the check valve 9 can also improve the reliability of the operation of the heater 7. Therefore, when the laundry processing apparatus 100 is drying, the airflow driving member 3 drives the airflow to the heater 7 so that the heater 7 heats the airflow passing through the heater, and the heated airflow passes through the one-way valve 9 and the flow guiding passage 52 and flows into the inner tub 2 so as to dry the laundry.

In addition, the laundry processing apparatus 100 according to the embodiment of the present invention further includes a base, a box, a working frame, etc., wherein the box is disposed on the base, the outer tub 1 is disposed in the box, the working frame is disposed on the top of the box, the working frame is provided with an opening opposite to the input opening, the opening is provided with a door cover, and the working frame is provided with a control panel or a control button, etc. Other structures of the laundry treating apparatus 100 are well known to those skilled in the art and will not be described in detail herein.

Then, a faucet is opened, a proper amount of water is injected into the inner barrel 2 through the water inlet c, a proper amount of detergent is put in through the water inlet c, then the airflow driving piece 3 starts to work, airflow is driven by the airflow driving piece 3 to enter the inner barrel 2 from the flow guide channel 52 and the communication hole a, water and the airflow are fully mixed under the rotation of the impeller 6 to form airflow to wash clothes, meanwhile, the airflow in the inner barrel 1 and the outer barrel 1 can be discharged from the exhaust hole b or the water inlet c, and redundant water and foam in the outer barrel 1 are discharged from the overflow hole d. After the washing is completed, the operation of the airflow driving member 3 is stopped, the drain valve is opened, and the washing water in the inner and outer tub 1 is discharged to the sewer through the drain pipe from the communication hole a, the guide passage 52 and the drain valve. At this time, the dehydration mode is started, the inner barrel 2 rotates relative to the outer barrel 1 to realize the purpose of dehydration, and the drain valve is always in an open state in the dehydration process.

After the dehydration is finished, the drain valve is closed, the airflow driving part 3 is opened, the heater 7 is opened, namely, the drying mode is started, the airflow driving part 3 drives the airflow to flow to the heater 7, the heater 7 heats the airflow flowing through the heater, the heated airflow enters the inner barrel 2 through the check valve 9, the flow guide channel 52 and the communicating hole a so as to achieve the purpose of drying clothes, and water vapor generated in the drying process is discharged into a sewer from the exhaust hole b and the overflow hole d. After drying is completed, the user can open the cover plate 42 and take the dried laundry.

It can be understood that, in the drying process, in order to improve the drying effect, at least one of the pulsator 6 and the inner tub 2 may be rotated, that is, the inner tub 2 may be rotated to drive the laundry to turn over, the pulsator 6 may be rotated to drive the laundry to turn over, and the inner tub 2 and the pulsator 6 may be rotated simultaneously to drive the laundry to turn over.
