Wherein, agitation wheel for washing machine of the present invention, as shown in Figure 1, comprise a big wave wheel 1, big wave wheel 1 is arranged at bottom inner tank of washing machine, and big wave wheel 1 is connected with the drive unit of washing machine, drives big wave wheel 1 forward or reverse by drive unit, thus clothing in stirring inner core and washings, reach the object of washing clothes.
Big wave wheel 1 comprises big wave wheel chassis 2 and many first convex tendons 3, big wave wheel chassis 2 entirety is in the arc raised up gradually to center by edge, first convex tendon 3 with big wave wheel chassis 2 central boss for starting point is radially arranged to edge, for ensureing slippage and the upset requirement of clothing, the quantity of the first convex tendon 3 can be 3-6 bar, and in the present embodiment, the quantity of the first convex tendon 3 is 3.
Every bar first convex tendon 3 comprises again first muscle 4 and the first little muscle 5, before and after first muscle 4, width is equal, first little muscle 5 is arranged at the top of first muscle 4, first muscle 4 and the first little muscle 5 form vertical riser shape structure, the radial section of first muscle 4 and the first little muscle 5 is streamlined, and its stage casing is to recessed arc.When big wave wheel 1 rotates, this structure can make load clothing easily along the surface upwards slippage of the first convex tendon 3, load clothing can also be made to overturn easily in the process of upwards slippage simultaneously, carry high-detergency.
As shown in Figure 1, be provided with a small wave wheel 6 in the position of the central protuberance of big wave wheel 1, small wave wheel 6 is relatively rotated and up-and-down movement up and down relative to big wave wheel 1 by link gear.
Link gear comprises impact rod 7 and sliding chassis 8, impact rod 7 be arranged at the below of small wave wheel 6 and be fixedly connected with small wave wheel 6, as shown in Figure 2, impact the cylindrical structural that rod 7 is roughly hollow, the top impacting rod 7 is provided with multiple mounting structure 9, impacts rod 7 by being fixed together with securing members such as screws between mounting structure 9 and small wave wheel 6.Impact rod 7 to be fixedly connected with the mode of buckle also can be adopted between small wave wheel 6.
Sliding chassis 8 is arranged at the below impacting rod 7, and sliding chassis 8 and big wave wheel 1 are fixed together by screw, and as shown in Figure 3, sliding chassis 8 is also roughly the cylindrical structural of hollow, and the top of sliding chassis 8 has a slip curved surface 10.As shown in Figure 2, there are in the bottom impacting rod 7 two cams 11 given prominence to downwards be oppositely arranged, slidingly contact between the bottom of two cams 11 and slip curved surface 10, when impacting rod 7 or sliding chassis 8 rotates, the cam 11 impacted bottom rod 7 slides along slip curved surface 10, impact rod 7 simultaneously under the effect of slip curved surface 10, do upper and lower up-and-down movement, and then drive small wave wheel 6 to do upper and lower up-and-down movement.
The position of the central protuberance of big wave wheel 1 has the cavity 12 of a column type, and the impact rod 7 in link gear and sliding chassis 8 are arranged in this cavity 12, and small wave wheel 6 is positioned at the top of this cavity 12.
The top of the central protuberance of big wave wheel 1 is provided with ring-shaped groove 13, the sidewall of small wave wheel 6 to be inserted in ring-shaped groove 13 and to fit with the outside side wall of ring-shaped groove 13, the rotation and lifting that can prevent from the foreign matter in inner core from entering affecting small wave wheel 6, also play a part spacing simultaneously, prevent small wave wheel 6 from producing when rotating and rock.
Cavity 12 inwall of big wave wheel 1 inwardly stretches out and is provided with several location claw 14, correspondingly on the outer wall impacting rod 7, be provided with two snap rings 15, the external diameter of snap ring 15 and the diameter compatible of cavity 12 close, and the cooperation of location claw 14 and snap ring 15 can prevent impacting rod 7 and deviate from from cavity 12.Meanwhile, arranging of snap ring 15 can also to impacting the effect that excellent 7 play spin balancing.
As shown in Figure 1, small wave wheel 6 comprises small wave wheel chassis 16 and many second convex tendons 17, small wave wheel chassis 16 entirety is in a plane, second convex tendon 17 with small wave wheel chassis 16 central boss for starting point is radially arranged to edge, for ensureing clothing upset requirement, the quantity of the second convex tendon 17 can be 3-5 bar, and in the present embodiment, the quantity of the second convex tendon 17 is 3.
Every bar second convex tendon 17 comprises again second largest muscle 18 and the second little muscle 19, before and after second largest muscle 18, width is equal, second little muscle 19 is arranged at the top of second largest muscle 18, second largest muscle 18 and the second little muscle 19 form vertical riser shape structure, the radial section of second largest muscle 18 and the second little muscle 19 is streamlined, and its stage casing is convex arc, this structure is more conducive to driving small wave wheel 6 to rotate when load clothing is more, improves the auxiliary clean result of small wave wheel 6.
Upon actuation, drive unit drives big wave wheel 1 forward and reverse alternate rotation to washing machine, and load clothing is stirred under the drive of big wave wheel 1, and clothing is along the surface upwards slippage of the first convex tendon 3 on big wave wheel 1.Simultaneously, because the rotation of big wave wheel 1, sliding chassis 8 is driven to rotate, the cam 11 impacted bottom rod 7 slides along slip curved surface 10, impact rod 7 under the effect of slip curved surface 10, do upper and lower up-and-down movement, and then drive small wave wheel 6 to do upper and lower up-and-down movement, clothing can be broken up when small wave wheel 6 does vertical motion upwards, and then effectively prevent clothing to be wound around.And small wave wheel 6 is when moving up and down, drive clothing upwards slippage further, load clothing can be made to be overturn easily in the process of upwards slippage simultaneously, and then can high-detergency be carried, for the washing machine of same capacity, load clothing is more, and rollover effect is then better.In washing process, due to the continuous stirring of clothing, load clothing applies pressure to small wave wheel 6, and small wave wheel 6, under the effect of load clothing, can constantly rotate, its speed of rotating is different from big wave wheel 1, the rotation of small wave wheel 6 can drive impact rod 7 to do upper and lower up-and-down movement equally, and certain washing function is also played in the rotation of small wave wheel 6, auxiliary performance clean result, particularly when load clothing is more, its auxiliary clean result is just more obvious.
Embodiment two:
Be with embodiment one difference, as shown in Figure 5, the top of sliding chassis 8 has a sliding bevel 20.As shown in Figure 4, there is in the bottom impacting rod 7 cam 11 given prominence to downwards, slidingly contact between the bottom of two cams 11 and sliding bevel 20, when impacting rod 7 or sliding chassis 8 rotates, the cam 11 impacted bottom rod 7 slides along sliding bevel 20, impact rod 7 simultaneously under the effect of sliding bevel 20, do upper and lower up-and-down movement, and then drive small wave wheel 6 to do upper and lower up-and-down movement.
Other structure is identical with embodiment one, is no longer separately described in detail here.
As mentioned above, plan content given by reference to the accompanying drawings, can derive similar technical scheme.In every case be the content not departing from technical solution of the present invention, any simple modification done above embodiment according to technical spirit of the present invention, equivalent variations and modification, all still belong in the scope of technical solution of the present invention.
