The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the present invention is described in further detail:
Embodiment one:
The rotary drum washing machine of in family life, using always at present comprises a housing (not shown), and surface of shell is provided with control panel and is used to pick and place the door of clothing; In housing, be provided with urceolus (not shown) that is used to be filled with water and the inner core (not shown) that is used to wash; Wherein, urceolus is fixing not to be changeed, and inner core is arranged on the inboard of urceolus; Inner core is driven by the drive unit (not shown) and rotates; Have several on the barrel of inner core and be used to the perforate that supplies washings to pass through, be provided with impeller in the bottom of inner core, impeller drives through drive unit.Top at urceolus is provided with water inlet, is used to wash the water inlet with rinse cycle, is provided with water discharge outlet in the bottom of urceolus, the draining after being used to dewater.In washing process, clothing to be washed is placed in the inner core.
In washing machine, be provided with master controller; Be used to control washing machine washing, rinsing, dehydration supervisor; The user sends instruction through the button on the operation control panel to master controller; Master controller is operated according to each unit of commands for controlling washing machine that receives accordingly, until accomplishing whole program for washing.
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 the inner tank of washing machine bottom, 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; Thereby clothing and washings in the stirring inner core reach the purpose of washing clothes.
Every first convex tendon 3 comprises the first muscle 4 and the first little muscle 5 again; First muscle 4 front and back width equate; The first little muscle 5 is arranged at the top of first muscle 4; The first muscle 4 and the first little muscle 5 form vertical riser shape structure, and the radially section of the first muscle 4 and the first little muscle 5 is streamlined, and its stage casing is to recessed arc.When big wave wheel 1 rotated, this structure can make the slippage that makes progress along the surface of first convex tendon 3 easily of load clothing, can also make the upset easily in the process of upwards slippage of load clothing simultaneously, improves the rate of cleaning.
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 relatively rotates and up-and-down movement up and down with respect to big wave wheel 1 through link gear.
Link gear comprises impact rod 7 and sliding chassis 8; Impact rod 7 is arranged at the below of small wave wheel 6 and is fixedly connected with small wave wheel 6; As shown in Figure 2; Impact the cylindrical structural that rod 7 is roughly hollow, the top of impacting rod 7 is provided with a plurality of mounting structures 9, impacts rod 7 through being fixed together with securing members such as screws between mounting structure 9 and the small wave wheel 6.Impacting between rod 7 and the small wave wheel 6 also to adopt the mode of buckle to be fixedly connected.
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 the link gear is arranged in this cavity 12 6 tops that are positioned at this cavity 12 of small wave wheel with sliding chassis 8.
Top in the central protuberance of big wave wheel 1 is provided with ring-shaped groove 13; The sidewall of small wave wheel 6 is inserted in the ring-shaped groove 13 and with the outside sidewall of ring-shaped groove 13 and fits; Can prevent that the foreign matter in the inner core from getting into rotation and the up-down that influences small wave wheel 6; Also play a part simultaneously spacingly, prevent that small wave wheel 6 from producing to rock when rotating.
On cavity 12 inwalls of big wave wheel 1, inwardly stretch out and be provided with several location claw 14; The outer wall that correspondingly impacts rod 7 is provided with two snap rings 15; The external diameter of snap ring 15 matches with the internal diameter of cavity 12, and the cooperation of location claw 14 and snap ring 15 can prevent to impact rod 7 and from cavity 12, deviate from.Simultaneously, snap ring 15 be provided with can also impact rod 7 play the effect of 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 integral body are a plane, and second convex tendon 17 is that starting point is radial setting to the edge with small wave wheel chassis 16 central boss, for guaranteeing clothing upset requirement; The quantity of second convex tendon 17 can be the 3-5 bar, and the quantity of second convex tendon 17 is 3 in the present embodiment.
Every second convex tendon 17 comprises the second largest muscle 18 and the second little muscle 19 again; Second largest muscle 18 front and back width equate that the second little muscle 19 is arranged at the top of second largest muscle 18, and the second largest muscle 18 and the second little muscle 19 form vertical riser shape structure; The radially section of the second largest muscle 18 and the second little muscle 19 is streamlined; And its stage casing is convex arc, and this structure more helps driving small wave wheel 6 more for a long time at the load clothing rotates, and improves the auxiliary clean result of small wave wheel 6.
Washing machine is after startup, and drive unit drives big wave wheel 1 forward and reverse alternate rotation, and load clothing quilt under the drive of big wave wheel 1 is stirred, the clothing slippage that makes progress along the surface of first convex tendon 3 on the big wave wheel 1.Simultaneously; Because the rotation of big wave wheel 1 drives sliding chassis 8 and rotates, the cam 11 that impacts excellent 7 bottoms slides along slip curved surface 10; Impact rod 7 and under the effect of slip curved surface 10, do up-and-down movement up and down; And then drive small wave wheel 6 and do up-and-down movements up and down, can clothing be broken up during vertical motion that small wave wheel 6 is done upwards, and then prevent that effectively clothing from twining.And small wave wheel 6 is when moving up and down, and further drives the clothing slippage that makes progress, can make simultaneously the load clothing in the process of upwards slippage by upset easily; And then can improve clean rate; With respect to for the washing machine of capacity, the load clothing is many more, and rollover effect is then good more.In washing process, because the continuous stirring of clothing, the load clothing is exerted pressure to small wave wheel 6; Small wave wheel 6 can constantly rotate under the effect of load clothing, and the speed of its rotation is different with big wave wheel 1; The rotation of small wave wheel 6 can drive equally impacts rod 7 do up-and-down movements up and down, and certain washing function is also played in the rotation of small wave wheel 6, auxiliary performance clean result; Particularly at the load clothing more for a long time, its auxiliary clean result is just more obvious.
Embodiment two:
Be that 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; Has an outstanding cam 11 downwards in the bottom of impacting rod 7; Sliding-contact between the bottom of two cams 11 and the sliding bevel 20, when impacting rod 7 or sliding chassis 8 rotations, the cam 11 that impacts excellent 7 bottoms slides along sliding bevel 20; Impact rod 7 simultaneously and under the effect of sliding bevel 20, do up-and-down movement up and down, and then drive small wave wheel 6 is done up-and-down movement up and down.
Other structure is identical with embodiment one, describes in detail no longer in addition here.
As stated, in conjunction with the given scheme content of accompanying drawing, can derive the similar techniques scheme.In every case be the content that does not break away from technical scheme of the present invention, to any simple modification, equivalent variations and modification that above embodiment did, all still belong in the scope of technical scheme of the present invention according to technical spirit of the present invention.
