The circumferential flow guiding ribs 31 of each flow guiding structure 3 of the embodiment are arranged at intervals along the inner peripheral edge 6 of the body 2, the intervals are water outlets 42 reserved with flow guiding channels 4, the intervals can be the same or different, and in a preferred scheme, the circumferential flow guiding ribs 31 are uniformly distributed along the inner peripheral edge 6 of the body 2, and the intervals are the same. So, processing is convenient, and the homogeneity of rivers dispersion is also better.
The end part of the same side of the circumferential flow guiding rib 31 of each flow guiding structure 3 is connected with the corresponding extending flow guiding rib 32, and the other end extends. So, the water conservancy diversion structure 3 of a plurality of "L" types is then with the direction, equidistance along circumference align to grid under body 2 on the terminal surface, consequently, the no dead angle of the water conservancy diversion passageway 4 that adjacent water conservancy diversion structure 3 formed, it is little to the hindrance of rivers, rivers wash away the play water end blowout from water conservancy diversion passageway 4 that can be smooth and easy behind the water conservancy diversion passageway 4, therefore the power of rivers is sufficient, through the play water end of narrowing again, can further increase water pressure, the stroke that the injection got into interior bucket is big, it is better to spray the effect.

As shown in fig. 4 to fig. 6, the present embodiment is a further limitation of the first embodiment, and the difference between the present embodiment and the second embodiment is: the extending flow guiding rib 32 of the embodiment extends linearly, one end of the extending flow guiding rib is connected with the peripheral flange 5, and the other end of the extending flow guiding rib is connected with the end part of the circumferential flow guiding rib 31 and is in smooth transition.
The extension water conservancy diversion muscle 32 of this embodiment is the linear type, and the slope sets up between periphery and internal periphery, meets and forms the contained angle that is greater than the right angle with the tip of circumference water conservancy diversion muscle 31, so, promotes leading-in to the water conservancy diversion passageway 4 that rivers of outer bung 1 periphery can be smooth and easy, and then the blowout. The consumption of water flow energy is small, and the power of the motor required for forming the jet water flow is small. The linear type extension water conservancy diversion muscle 32 processing is convenient, sets up with the contained angle of circumference water conservancy diversion muscle 31 easily, arranges convenient pleasing to the eye, and the water conservancy diversion is effectual.
Preferably, the connection between the extending flow guiding rib 32 and the circumferential flow guiding rib 31 is a rounded structure. The structure can further reduce the blocking effect on water flow and reduce the consumption of water flow power.
In addition, the circumferential flow guiding rib 31 of the embodiment may also be made into a stepped structure 31-1, and the stepped structure 31-1 gradually descending is arranged from one end connected with the extending flow guiding rib 32 to the extending end, so that the water flow is divergently sprayed out.
The inner peripheral edge 6 of the main body 2 of the present embodiment extends and tilts upwards at least at the position of the water outlet end of each flow guiding structure 3, so as to increase the water flow lift.
Example four
The embodiment provides a washing machine, the washing machine is provided with an outer barrel cover 1 of the washing machine according to any one or combination of the first embodiment to the third embodiment, and the outer barrel cover 1 is arranged on the upper part of an outer barrel of the washing machine. The periphery of the outer barrel cover 1 is hermetically connected with the outer barrel, during washing, the motor drives the impeller and the inner barrel to rotate, so that water flow is driven to rotate, under the action of centrifugal force generated by high-speed rotation, the water flow can be lifted along the inner barrel and the outer barrel, when reaching the outer barrel cover 1, the water flow enters a flow guide channel 4 formed by a flow guide structure 3 on the lower end face of the outer barrel cover 1 along the rotating direction, and then is sprayed out from a narrowed water outlet end to form dispersed spray water flow which is sprayed on clothes in the inner barrel.
Although the present invention has been described with reference to a preferred embodiment, it should be understood that various changes, substitutions and alterations can be made herein without departing from the spirit and scope of the invention as defined by the appended claims.
