Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention.
All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention. The embodiments described below and the features of the embodiments can be combined with each other without conflict.
At present, the flange of the pulsator washing machine may be classified into a forged flange and a cast flange according to the manufacturing method. The forging is a processing method for obtaining a forging with certain mechanical property, certain shape and size by applying pressure to a metal blank by using a forging machine to generate plastic deformation. The shape of the forged flange can be gradually forged into a blank through the working procedures of thickening, drawing, bending, punching, cutting and the like. It will be appreciated that the structural strength of the forged flange increases with its thickness. However, due to the limitation of the process, the thickness of the forged flange may be about 6mm at most, and the thickness may not be enough to meet the requirement of the pulsator washing machine for high-speed rotation of the flange.
In addition, the casting is a technological process of melting metal into liquid meeting certain requirements, pouring the liquid into a casting mold, cooling, solidifying and cleaning to obtain a casting (part or blank) with a preset shape, size and performance. Although the cast flange can realize complex modeling, the cast flange has the risk of 'brittle fracture' due to casting defects (air holes, cracks and inclusions) and poor streamline of internal tissues of a casting.
To sum up, in order to satisfy rotary drum washing machine's flange high rotational speed operating mode requirement, this application provides a flange structure and washing machine, can effectively improve the structural strength of flange, extension washing machine's life.

The lower extreme of flange structure can be opened and be equipped with standing groove 6, and standing groove 6 can rotate relative the clutch. The output shaft of the clutch can penetrate through and be fixed in the central hole 7, and the fastening piece can be connected with a threaded hole in the inner ring section so that the output shaft and the flange can be connected. Thus, the output shaft, the flange structure and the inner cylinder 5 can rotate synchronously. The side of the clutch facing away from the standing groove 6 can be connected to the tub of the washing machine. After the clutch is started, the output shaft of the clutch drives the flange structure to rotate, and further drives the inner barrel 5 to rotate, so that the aim of cleaning clothes of a user is fulfilled by utilizing the centrifugal motion of the inner barrel 5.
In one possible implementation, the inner barrel 5 and the flange structure are connected by fasteners.
In one possible implementation manner, the bottom wall of the inner cylinder 5 is provided with a through hole, and at least part of the flange structure penetrates through the through hole and extends into the inner cylinder 5 so as to form an inclined surface for the washing water to flow through.
Specifically, the outer ring section of the flange structure may be located below the cylinder bottom of the inner cylinder 5, and the upper portions of the inner ring section and the radial section of the flange structure may be higher than the cylinder bottom of the inner cylinder 5. It will be appreciated that the gap between two adjacent radial segments, i.e. the leakage orifice, can be used for the discharge of wash water from the inner drum 5 into the outer drum.
