The specific embodiment

Fig. 1-3 has showed the washing machine that has damping device according to an embodiment of the invention.This washing machine comprises cabinet 1, and washing facility is contained in this cabinet, and described washing facility comprises the traditional washtub 2 of substantial cylindrical, and described washtub 2 comprises cylinder 3, and described cylinder 3 is rotatable with respect to rotating shaft A; Rotating shaft A preferably overlaps with the central symmetry axis of washtub 2.Rotatable cylinder 3 is suitable for holding clothes to be washed.

Bucket 2 resiliency supported are in cabinet 1 and have the washing machine that belongs to traditional, all devices of load and drain detergent and cleaning solution.

This washing machine also comprises balancing weight 6 and 61, motor 7 and zone 71, described balancing weight 6 and 61 be arranged on the top of washtub 2 and below, described motor 7 traveling roller 3 in washtub 2, the control appliance of this washing machine, knob, button etc. are installed in zone 71.

This washing machine comprises element 4-damper or spring, and described element 4 is anchored into the top 20 of washing machine and is anchored into the roof 10 of cabinet 1, and is suitable for making washtub 2 to keep being suspended in the cabinet 1.This washing machine also comprises a pair of damper 5, and described damper 5 is anchored into the bottom 11 of cabinet 1 and is anchored into the bottom 21 of washtub 2.Damper 5 is preferably friction-type or fluid pressure type, and can subdue vibrations in washing and/or the centrifugation step of the cylinder of washtub with damper or spring 4.Damper 5 and damper or spring 4 preferably arrange along suspended axle F.

Washtub 2 is contained in the cabinet 1, makes the diapire 23,24 of washtub be parallel to rear wall 12 and the antetheca 13 of cabinet 1 toward each other and preferably; Concerning front loading formula washing machine, the antetheca 13 of cabinet 1 refers to the wall and the wall relative with it of opening to load clothes to be washed respectively with rear wall 12, to with regard to top load mode washing machine, the antetheca 13 of cabinet 1 and rear wall 12 are the wall relative with the diapire 23,24 of washtub 2.With regard to the front loading formula washing machine of describing among Fig. 1-3, described diapire 23,24th, relative, and preferred parallel with antetheca 13 with the rear wall 12 of cabinet 1, and circular side wall 25 is relative with diapire 11 with the roof 10 of

sidewall

14,15 and cabinet.

Washtub 2 forms tub assembly 200 with rotatable cylinder 3 and motor 7, and described tub assembly 200 is supported by spring 4 and damper 5.

If the shock transfer that tub assembly 200 produces is to cabinet 1, vibrations will reduce the reliability of washing machine and may produce disagreeable noise.

According to the present invention, in order to make tub assembly in washing and the centrifugation step, and particularly the mobile vibrations of transmitting of the axle of washtub 2 minimize, this washing machine comprises a pair of damper 50, described damper 50 is anchored into the circular side wall 25 of washtub 2 and is anchored into rear wall 12 or the antetheca 13 of cabinet 1, preferably is anchored into the rear wall 12 of cabinet 1.

The anchor point of the damper of a pair of damper 50 on the sidewall 25 of washtub 2 is preferably with respect to roughly symmetrical manner setting of perpendicular B, preferably the wall 11 with the bottom of cabinet 1 is vertical, pass the central shaft A of washtub, and its distance B 1 is littler than the diameter D of washtub.

The damper of a pair of damper 50 is preferably long than the distance B 2 between the anchor point of the damper 5 on the sidewall 25 of washtub in the distance B 1 of the anchor point on the sidewall 25 of washtub.

It is first apart from the T1 place that the anchor point of the damper of a pair of damper 50 preferably is arranged on apart from the bottom 11 of cabinet 1, first apart from T1 than from the bottom 11 of cabinet to damper 5 at the second distance T2 of the anchor point on the sidewall of washtub long and short apart from T than between the bottom 11 of central shaft A and cabinet 1.Like this, with respect to known washing machine, the size of cabinet 1 and washtub 2 does not need to change.

Preferably, the anchor point of damper 50 on the sidewall 25 of washtub 2 is at the certain distance F1 place with respect to the suspended axle F that passes damper 5 and spring or damper 4.

The damper of a pair of damper 50 preferably is set to bottom 11 almost parallels with the cabinet 1 of washing machine.

Damper 50 is preferably friction-type or the hydraulic with piston 51, and described piston 51 slides in cylinder 52.Cylinder 52 is anchored into rear wall or the antetheca of cabinet 1 by joint 53.

Joint 53 may be for universal, and be connected to antetheca or the rear wall of cabinet 1, makes cylinder (Fig. 4) or vertical direction (Fig. 5) swing in the horizontal direction.By the antetheca that is connected to cabinet 1 shown in Figure 4 or the universal joint of rear wall, damper 50 restriction tub assemblies 200 are swung at vertical direction, and can be considered the system for the swing of correcting tub assembly 200.By the antetheca that is connected to cabinet 1 shown in Figure 5 or the universal joint of rear wall, the teeter of damper 50 restriction tub assemblies 200 promotes tub assembly swing vertically simultaneously.

As the substitute of universal joint 53, damper 50 has ball-and-socket joint 54, and described ball-and-socket joint makes swing can carry out (Fig. 6) in any direction.

Although the washing machine shown in Fig. 1-3 is the front loading formula, change according to an embodiment of the invention, this washing machine can be the top load mode, shown in Fig. 7 and 8; In this case, damper 50 is anchored into the sidewall 25 of washtub 2 again and is anchored into diapire 23 with washtub, the wall of 24 relative cabinets 1, but uniquely comparatively speaking with washing machine among Fig. 1-3 different be, damper 50 may preferably be arranged on the axle F of standard connection washtub 2 and cabinet 1 in the fixed position of the sidewall 25 of washtub, that is, roughly along the fixing suspended axle F of damper 5.Fig. 7 and 8 top load mode washing machine also comprise balancing

weight
