Description
The cross reference of related application
The application is based on the priority of korean patent application P2002-0064331 requirement this application of submitting on October 21st, 2002, and the full content of this application is hereby incorporated by.
Technical field
The present invention relates to a kind of washing machine, more particularly, the present invention relates to be used for the dynamic shock-absorber that washing machine is absorbed in the vibration that washing process takes place.
Background technology
In general, washing machine is a kind of by chemical emulsification effect that utilizes washing powder and the device of the mechanical impact of clothing being removed the various dirts on the clothing with the friction and the impeller of water.Washing machine is divided into drum-type, impeller-type and agitator type washing machine.
With regard to tumbling-box washing machine,, wash by consequent bump because the rotation of cylinder makes clothing roll up and down.With regard to impeller-type and agitator type washing machine, the effect by washing powder and the rotation of impeller or agitator make the clothing bump that is produced that rolls up and down wash, and impeller or agitator are connected on the wash shaft of stretching out from the washing machine intermediate vertical.Aforementioned washing machine is that the bump that produces by mechanical system washs.
Hereinafter, be explained with reference to the drawings the general structure of pulsator washing machine.As shown in Figure 1, the outer bucket 1 of formation washing machine shell is arranged on and is used for depositing water in the casing (not shown).Between bucket 1 and the casing, a damper (not shown) is set supports outer bucket 1, outside so that be absorbed in the vibration that is produced in washing and the dehydration.
Interior bucket 1 can be rotatably set in the outer bucket 1, and impeller 3 is arranged in interior barrel 2.Balancer 14 is set with the balance in the bucket rotation process maintenance in interior bucket upper end, and a drive motors 5 is set rotates interior bucket, barrels 2 bottom in impeller 3 is arranged on.
Explain that in more detail driving shaft 4 is connected in impeller 3, drive motors 5 is connected in the bottom of driving shaft 4.Bearing housing 8 is arranged between the bottom and drive motors 5 of outer bucket 1.Bearing 6 and 7 can be rotatably set in the top of bearing housing 8 and bottom and is used for supporting driving shaft 4.Therefore, when drive motors 5 running makes driving shaft 4 left and when turning right, the impeller 3 and the interior bucket 2 that are connected in driving shaft 4 rotate mutually, and produce the washing current in case in interior bucket 2 washing clothes.

The specific embodiment
Now the preferred embodiments of the present invention are described in detail, the example of embodiment is shown in the drawings.In possible place, all accompanying drawing will use identical Reference numeral to represent identical or similar parts.
As shown in Figure 2, be arranged in the casing of washing machine in order to the outer bucket 1 of depositing water, interior bucket 2 can be rotatably set in the outer bucket 1.Outer bucket 1 is supported by a plurality of damper (not shown) that the washer cabinet (not shown) are connected in the outer bucket in the washing machine.
Dynamic shock-absorber 10 comprises: be connected in the fixed part 11 of outer surface of bearing housing 8 and dynamic damping means as shown in Figure 3A.This dynamic damping means comprises extension component and block parts 13.Along radially extending and vibration, block parts 13 are around the external peripheral surface setting of extension component 12 from the external peripheral surface of fixed part 11 for discoidal extension component.Block parts 13 vibrate with extension component 12 in bucket 1 vibration processes outside, and absorb the higher vibration of outer bucket 1 speed.
Fixed part 11 can be set to various ways.For example, be connected at fixed part 11 under the situation of external peripheral surface of cylinder-shaped bearing case 8, this fixed part forms annular.Extension component 12 comprises a metal dish or a plastic disc, and metal dish has fixing rigidity and vibration.And block parts 13 can be set to various ways with vibration damping more effectively.
Having first end of the external peripheral surface that is connected in fixed part 11 and many roots 12a of second end of the inner circumferential surface that is connected in extra block body component 13 is arranged on the upper surface of the extension component 12 shown in Fig. 3 B.In extension component 12 vibration processes, rib 12a supports and the connection extension component.Rib 12a is arranged on the bottom surface of extension component 12 or is arranged on the end face and the bottom surface of extension component.And shown in Fig. 3 C, extension component 12 comprises a plurality of equidistant bar that extends along radially.
Simultaneously, the structure member of dynamic shock-absorber 10 can separately be produced and assemble, and perhaps all parts can form a monolithic entity.In this example, perhaps extension component 12 and block parts 13 or fixed part 11 and extension component 12 form a monolithic entity.And each parts that constitute dynamic shock-absorber 10 can interconnect and dismantle.
In dehydration, the extension component 12 of dynamic shock-absorber 10 and the rigidity of block parts 13 and quality can suitably be adjusted to fixing vibration mode.In dehydration, regulate according to rigidity, capacity and the rated speed of outer bucket 1.
Explained later is according to the operation with dynamic shock-absorber 10 of aforementioned structure of the present invention.When washing machine began to dewater, driving shaft 4 was owing to the running of drive motors 5 is rotated, and impeller 3 and interior bucket 2 high speed rotating are dewatered.
At this moment, the rotation owing to driving shaft 4 and interior bucket 2 produces vibration.This vibration transfer is to bearing housing 8.And the extension component 12 of dynamic shock-absorber 10 and block parts up-down vibration are so that absorb the vibration of outer bucket 1.
As shown in Figure 4, outer bucket 1 comprises end face with the annular of being set to and the support component 14 of the holddown groove 14a on barrel 1 bottom surface outside.Fixed part 11 can be put into the holddown groove 14a of support component 14, and is fixed by the screw (not shown).The rib (not shown) that plays fixation can additionally be provided with in support component 14 place's support fixation elements 11.
Effect of the present invention is as follows: at first, in dehydration, dynamic shock-absorber 10 absorbs because the relative vibration of the outer bucket 1 that the high speed rotating of interior bucket 2 produces.Shock absorption is compared more remarkable with traditional washing machine.The second, in dehydration, realized low vibration and low noise.The 3rd, because relative vibration produced and the vibration that be sent to driver part of bucket 1 has reduced outward, and the guard block life-saving.The 4th, in dehydration, the vibration that predetermined number of revolutions produces can reduce by the rigidity and the quality of regulating dynamic shock-absorber 10, and the number of times of specified rotation can be set to higher value so that reduce dewatering time.
Under the situation that does not deviate from spirit of the present invention or scope, can improve and change the present invention, this is conspicuous for the person of ordinary skill of the art.Therefore, present invention resides in improvement and change and their equivalent that carries out in the claims scope.
