The front-loading washing machine according to  claim 2 , wherein when the access port is located at the non-washing position, the access port is driven to move close to an upper edge of the front panel, and when the access port is located at the washing position, the access port is driven to move close to a lower edge of the front panel. 
     
     
         4 . The front-loading washing machine according to  claim 1 , wherein the driving mechanism is configured to drive the access port to move upwards to close to an upper edge of the front panel and move downwards to close to a lower edge of the front panel. 
     
     
         5 . The front-loading washing machine according to  claim 1 , wherein a motion range of the access port in the opening is configured in such a manner that an included angle between a central axis of the access port and a horizontal plane ranges from 0° to 90°. 
     
     
         6 . The front-loading washing machine according to  claim 1 , wherein the driving mechanism comprises:
 a longitudinal pushrod disposed at a front side of the tub;   a transverse shaft disposed at a rear side of the tub and coupled to the tub; and   a support frame disposed in the cabinet and having a hole,   wherein the transverse shaft is configured to rotate in the hole of the support frame.   
     
     
         7 . The front-loading washing machine according to  claim 2 , wherein the driving mechanism comprises:
 a longitudinal pushrod disposed at a front side of the tub;   a transverse shaft disposed at a rear side of the tub and coupled to the tub; and   a support frame disposed in the cabinet and having a hole,   wherein the transverse shaft is configured to rotate in the hole of the support frame.   
     
     
         8 . The front-loading washing machine according to  claim 1 , wherein the tub is provided with a carrying platform, and the door unit is rotatably mounted on the carrying platform along a circumferential direction of the access port. 
     
     
         9 . The front-loading washing machine according to  claim 8 , wherein the door unit comprises:
 a door base rotatably mounted on the carrying platform along the circumferential direction of the access port; and   a door body hinged to the door base.   
     
     
         10 . The front-loading washing machine according to  claim 9 , wherein the door base and the carrying platform are configured as circular rings fitted with each other and having central axes coincident with each other. 
     
     
         11 . The front-loading washing machine according to  claim 10 , wherein the door base is provided with a plurality of base mounting holes spaced apart from one another by an equal interval along a circumferential direction of the door base, the carrying platform is provided with a plurality of platform mounting holes spaced apart from one another by an equal interval along a circumferential direction of the carrying platform, and the door base and the carrying platform are fastened by threaded fasteners fitted in the base mounting holes and the platform mounting holes. 
     
     
         12 . The front-loading washing machine according to  claim 11 , wherein a central angle corresponding to two adjacent base mounting holes is integer times or one part in an integer as large as a central angle corresponding to two adjacent platform mounting holes. 
     
     
         13 . The front-loading washing machine according to  claim 10 , wherein the door body is provided with a door lock opposite to the door hinge in a radial direction of the door body, and the door base is provided with a door hook configured to be fitted with the door lock.
