Preferably, the sealing ring 530 has an annular connecting portion 550 at one end thereof for connecting the tub 200 around the opening 240, the air inlet 540 is disposed on the annular connecting portion 550, the air supply connecting member 600 is a rigid tube, the annular connecting portion 550 can vibrate synchronously with the tub 200, and the drying unit 100 is connected to the annular connecting portion 550 through the air supply connecting member, so that the air supply connecting member can keep relatively still with the tub 200, thereby reducing the wind resistance of the airflow entering the tub 200 from the drying unit 100 and improving the drying efficiency.

In addition, the blowing connection member 600 may also be a hose, since one end of the sealing ring 530 is connected to the casing 500 and is kept stationary with the casing 500, and the other end is connected to the outer tub 200 and can vibrate synchronously with the outer tub 200, the amplitude of the hose connected to the sealing ring 530 is asynchronous with the outer tub 200, but the hose is continuously deformed during the vibration of the outer tub 200 by the deformation capability of the hose to keep the drying unit 100 in communication with the air inlet 540. The hose is preferably integrally formed with the sealing ring 530, so that the difficulty of connecting the hose to the sealing ring 530 can be reduced.

The embodiment of the utility model provides a can be applied to products such as washing and drying all-in-one, dryer.

The above description is only for the specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto, and those skilled in the art should understand that the present invention includes but is not limited to the contents described in the drawings and the above detailed description. Any modification which does not depart from the functional and structural principles of the present invention is intended to be included within the scope of the claims.
