Description

Washing machine with damping device

Technical field

The present invention relates to washing machine, especially about the invention of washing machine aspect with damping device.

Background technology

In general, the washing machine of prior art comprises casing 1, urceolus 2 and inner core 3 as shown in Figure 1.Casing 1 constitutes the shell of washing machine; Urceolus 2 is located in the casing 1, is supported on the brake 10, is used to store washings; Inner core 3 is arranged on urceolus inside, and is rotatable, can place washing articles in the inner core 3.

Brake 10 is made of hanger lever 11 and suspension bracket cap 12.As shown in Figure 2, hanger lever 11 is arranged on the last angle of casing 1, extends to the bottom of urceolus 2 always, can turn; Suspension bracket cap 12 is arranged on the bottom of hanger lever 11, and the inside of suspension bracket cap 12 is built-in with spring 12a, and the upper end of suspension bracket cap 12 is arranged on around the bottom of urceolus 2, supports urceolus 2, can turn.Washing machine washs washings according to washing, draining, dehydration, can carry out rinsing, draining and dehydration repeatedly as required.

Work and effect to brake 10 in the washing machine course of work describes below:

During washing,, the vibration major part of the urceolus 2 that the rotation of inner core 3 produces absorbs because being braked device 10.That is to say, because when the rotation of inner core 3 causes urceolus 2 to produce vertical vibration or rocking vibration, suspension bracket cap 12 is along hanger lever 11 upper and lower moving, at this moment by being built in energy---the vibrational energy that spring 12a in the suspension bracket cap 12 and absorption of air move, the location restore that makes urceolus 2 is to original position.

But the washing machine with prior art of said structure has following shortcoming:

Because the rotation of inner core 3 is twined washing articles mutually, cause washing process or rinse cycle to be ended, the washing articles that twines when dewatering tilts to a side inwall of inner core 3, causes off-centre.Inner core 3 low speed rotation of dehydration initial stage off-centre cause urceolus 2 to produce the horizontal movement of rolling, as " H " of Fig. 1, and oscillating motion.That is to say that a lot of moisture are contained in the inside of dehydration initial stage washing articles, so offset is big, cause the vibration of urceolus 2 very serious.At the lower dehydration initial stage of rotating speed, washing machine itself has vibration frequency own, makes the vibration of urceolus severe more, produces very big vibration under the little state of centrifugal force, so the amplitude of urceolus is very big.In addition,, still there are urceolus 2 and the impingement phenomenon that casing 1 bumps against, casing is moved though brake 10 can suppress the horizontal vibration and the rocking vibration of transition.Simultaneously, because the rotation of inner core 3 and the vibration of urceolus 2 etc. cause the noise of casing 1 inside to transmit to the outside.

Summary of the invention

Technical problem to be solved by this invention provides a kind of by improving the structure of washing machine, reduces the vibration of urceolus, reduces the washing machine with damping device of the noise that box house produces simultaneously.

In order to address the above problem, the technical solution used in the present invention is: a kind of washing machine with damping device, comprise the shell that constitutes washing machine casing, be arranged on the urceolus that box house stores washings, the brake that absorbs the urceolus vibration when being arranged on casing upper support urceolus and washing, inner face at casing is provided with the shock-resistant member that absorption brake does not have the vibration of absorption, and the outside of shock-resistant member is attached to the inner face of casing; The inner peripheral surface of shock-resistant member and the outer peripheral face of urceolus keep specific distance, constitute concentric circles with urceolus.

Shock-resistant member is preferably avoided the position, corner of the residing casing of brake, is separately positioned on four inner faces of casing.

The inner peripheral surface of shock-resistant member preferably adopts concaveconvex shape, can absorb the noise that box house produces.

The invention has the beneficial effects as follows that the inner face by casing is provided with the washing machine of shock-resistant member, can reduce the vibration of urceolus, reduce the noise that box house produces simultaneously.Prevent impingement phenomenon and mobile phenomenon that the dehydration initial stage is easy to generate, also can prevent that the noise transmission of the vibration generation of urceolus from arriving the outside of casing simultaneously.

The specific embodiment

Below in conjunction with the drawings and specific embodiments the washing machine with damping device of the present invention is described in further detail:

As shown in Figure 3 and Figure 4, washing machine of the present invention comprises casing 1, urceolus 2, brake 10 and shock-resistant member 20.Casing 1 constitutes the shell of washing machine; Urceolus 2 is arranged on box house, stores washings; Brake 10 is arranged on the casing, supports urceolus 2, absorbs the vibration of urceolus during washing; Shock-resistant member 20 is arranged on the inner face of casing, and absorption brake 10 does not have the vibration of absorption.The outside of shock-resistant member 20 is attached to the inner face of casing 1; The inner peripheral surface 20a of shock-resistant member 20 and the outer peripheral face of urceolus 2 keep specific distance, constitute concentric circles with urceolus.

As shown in Figure 4, shock-resistant member 20 is preferably avoided the position, corner of brake 10 residing casings 1, is separately positioned on four inner faces of casing 1.

As shown in Figure 7, the inner peripheral surface 20a of shock-resistant member preferably adopts concaveconvex shape, can absorb the casing 1 inner noise that produces.

In addition, shock-resistant member 20 preferably utilizes sponge to make.

Below with reference to Fig. 5 and Fig. 6, the effect of the shock-resistant member 20 the when washing machine with said structure is worked is elaborated:

As shown in Figure 5, when the transient vibration of dehydration initial stage urceolus 2 made urceolus carry out oscillating motion, the brake 10 that supports urceolus bumped against with shock-resistant member 20, absorbs the transient vibration of urceolus 2.

As shown in Figure 6, the vibration of the transition that the dehydration initial stage produces makes the vibration of urceolus 2 have very big amplitude, when urceolus carries out oscillating motion and horizontal movement, support the brake 10 bump shock-resistant members 20 of urceolus, the inner peripheral surface of the outer peripheral face bump shock-resistant member 20 of urceolus 2, shock-resistant member 20 absorbs the vibration of the transition of urceolus.

The arrow of dotted line as shown in Figure 7, the urceolus 2 inner noises that produce are by concaveconvex shape, as if the inner peripheral surface 20a of the shock-resistant member of egg pallet shape reflection absorbs final the disappearance gradually.

Be provided with the washing machine of shock-resistant member by the inner face that casing is provided, can reduce the vibration of urceolus, reduce the noise that box house produces simultaneously.

In sum, the personnel that have general knowledge in technical field of the present invention can propose a lot of schemes in basic fundamental thought range of the present invention.
