Description

Wet clothes dewatering tub

The utility model relates to a kind of wet wash dehydration barrel that is driven running by motor in the bottom.

The dehydration barrel of the two-tub washing machine of Chu Shouing in the market, or independent wet wash dehydration barrel, drive in the bottom by motor ［ 4 ］, when clothing is put not enough balance in the bucket, staving ［ 2 ］ will pendulum impact urceolus ［ 3 ］ in the dehydration barrel running, make the people have to stop the running of dehydration barrel, again the clothing in the bucket is put balance, will dehydration barrel be run well sometimes.In automatic washing machine, in order to prevent dehydration barrel when running pendulum impact wash bucket, above the dehydration barrel staving, be provided with the fluid balance ring, in the ring of hollow garden liquid is housed, make the dehydration barrel of running keep balance, but the dehydration barrel of two-tub washing machine or independent wet wash dehydration barrel all are not provided with bascule.

The purpose of this utility model provides a kind of dehydration barrel of two-tub washing machine or independent wet wash dehydration barrel, can eliminate or reduce the phenomenon of dehydration barrel staving collision urceolus when its clothing in bucket is put not enough balance.

In order to solve above-mentioned task, the solution that the utility model adopts is: install weight on week in garden, dehydration barrel staving top to increase the rotary inertia on staving top, the performance of opposing unbalanced moments when improving the dehydration barrel running, with eliminate or when reducing the dehydration barrel running inner clothing uneven and make the phenomenon of staving collision urceolus.Staving and motor link together by shaft joint, motor is supported on three or several shock-absorbing springs, when the radial push staving makes its deflection, staving will serve as that the swing fulcrum produces swing with several strong points of motor, the swing fulcrum of Here it is staving.During the dehydration barrel running, each particle of clothing all can produce centrifugal force in each particle on the bucket wall and the bucket, the centrifugal force that above-mentioned particle produces can produce moment to the swing fulcrum of staving, goes up symmetry direction staving garden week and can cancel out each other to the moment that staving swing fulcrum produces.If also remain bigger moment in certain direction behind the partial offset mutually, this unbalanced moments will make the staving of rotation produce swing, can make staving collision urceolus when serious.If install the rotary inertia that weight increases staving top on week in garden, staving top, and the centrifugal force that this weight produces when staving is rotated equals zero to the resultant moment of staving swing fulcrum or near equalling zero, when rotating, dehydration barrel will produce bigger rotator inertia, interference free performance when this bigger rotator inertia can improve the dehydration barrel running, can reduce so that eliminate the unbalanced moments that the clothing imbalance is produced in the bucket making a barrel swing that causes, make it not collide with urceolus.The degree of unbalancedness that clothing is put at every turn in the dehydration barrel all changes, and the rotary inertia on staving top should be increased to and make staving pendulum impact urceolus not in most cases.According to experiment, the rotary inertia of staving top installing weight reaches 0.3kg.m with the ratio of dehydration barrel area of section ²/ m ²Can play a role to the equilbrium running of bucket, along with the increase effect of this ratio is more and more big.In addition, the center of gravity of weight is higher, and the resistivity of during the dehydration barrel running unbalanced moments being disturbed is stronger.When ratio is increased to 8kg.m ²/ m ², and the weight center of gravity is positioned at staving height 1/2nd when above, can make staving all not collide urceolus under various conditions.

When the rotary inertia of staving top installing weight and dehydration barrel area of section ratio increased, the cost of dehydration barrel will correspondingly increase, and the starting torque of motor also can correspondingly increase.When ratio at 2-3kg.m ²/ m ², and the weight center of gravity is positioned at staving height 4/5ths (80%) when above, can make staving pendulum impact urceolus not in most cases.

The installing weight to be increasing its rotary inertia on the bucket wall of staving top, and the centrifugal force that weight produces when staving is rotated equals zero to the resultant moment of staving swing fulcrum or mainly contains near null way:

In bucket wall top installing annular weight;

Thickening bucket wall top;

Press five equilibrium garden week on bucket wall top and evenly install special-shaped weight;

Toroidal container at bucket wall top installing energy filling liquid;

Press the special-shaped container of five equilibrium garden week evenly installing the energy filling liquid on bucket wall top;

Except that above-mentioned way, also can be at the special-shaped weight of bucket wall garden week inhomogeneous installing in top, as long as the centrifugal force that these weights produce when staving rotates equals zero to the resultant moment of staving swing fulcrum or near equalling zero.

Owing to adopted in the above-mentioned solution at dehydration barrel staving top installing weight to increase the way of staving top rotary inertia, when being rotated, dehydration barrel produces bigger rotator inertia, when having improved the dehydration barrel running to the resistivity of unbalanced moments, so the problem of staving pendulum impact urceolus when having solved clothing in the dehydration barrel and putting not enough balance, thus can avoid making people's worry stop dehydration barrel and the operation of putting clothing repeatedly again repeatedly.At the rotary inertia on dehydration barrel top installing weight increasing staving top, the embodiment structure that has is very simple, and the cost increase seldom.Implementing this programme will make the starting torque of dehydration barrel motor increase to some extent.In addition, adopt this programme after, in case because clothing is put serious imbalance when staving and urceolus are collided, the strength of collision will be than originally greatly.
