The utility model provides a double-drum washing machine with vibration damping effect, as shown in figures 1-4, comprising a washing machine body 100, wherein the washing machine body comprises a frame body 10, a drum body, a connecting piece and a vibration damping suspension spring 50; wherein,
the barrel body comprises an upper barrel 310 and a lower barrel 320, the upper barrel 310 and the lower barrel 320 are positioned in the frame body 10, and the upper barrel 310 is positioned right above the lower barrel 320;
the upper tube 310 and the lower tube 320 are respectively connected to the frame 10 through the connecting members, so that the upper tube 310 and the lower tube 320 are suspended in the frame 10;
the damping suspension spring 50 is installed between the upper barrel 310 and the lower barrel 320, one end of the damping suspension spring 50 is connected with the lower end of the upper barrel 310, and the other end is connected with the upper end of the lower barrel 320; when the upper tube 310 and/or the lower tube 320 operate, the vibration force generated by the upper tube 310 and/or the lower tube 320 is attenuated by the damping suspension spring 50 and then transmitted to the frame 10. In one embodiment, people nowadays have higher living standard, and the quality of the washing machine is pursued while paying more attention to the sanitary condition, so that the double-drum washing machine is more and more popular in people's life. In general, a dual drum washing machine includes a lower drum 320 and an upper drum 310, the upper drum 310 is located right above the lower drum 320, and the mass of laundry accommodated in the upper drum 310 is smaller than that accommodated in the lower drum 320; in addition, when the upper tub 310 of the dual tub washing machine operates, the lower tub 320 lowers the center of the washing machine like a jack; when the lower tub 320 of the washing machine operates, the upper tub 310 presses the lower tub 320 as a weight. For the lower tube 310 to damp and support, generally by the damper and the suspension spring, it should be understood that: the lower barrel is arranged in the frame body of the washing machine through the lower support of the vibration absorber and the upper support of the hanging spring, and in addition, when the vibration is generated due to the rotation of the inner barrel of the washing machine, the vibration absorber and the hanging spring reduce the vibration generated on the lower barrel so as to reduce the vibration transmitted to the frame body.
Generally, the upper drum 310 and the lower drum 320 are supported and damped by the damper and the suspension spring, but the damper for the upper drum 310 is fixedly mounted on the middle cross beam 121 of the washing machine frame, which not only increases the complexity of the whole structure of the washing machine, but also enables the vibration generated during the operation of the upper drum to be transmitted to the washing machine frame only through the suspension spring or the damper, and the weakened vibration force is small, i.e. the damping effect is general. In this embodiment, the upper barrel 310 and the lower barrel 320 are connected by the damping suspension spring 50, and two ends of the damping suspension spring 50 are respectively connected to the outer walls of the upper barrel 310 and the lower barrel 320 of the washing machine; when the upper drum 310 and the lower drum 320 operate simultaneously, the vibration force generated by the upper drum 310 and the lower drum 320 is reduced by the damper suspension spring 50 through the suspension rod 20 and the damper 40, and is also reduced by the damper suspension spring 50, thereby improving the overall vibration damping effect of the washing machine. When the upper cylinder 310 or the lower cylinder 320 operates alone, that is, the upper cylinder 310 operates the lower cylinder 320 not to operate or the lower cylinder 320 operates the upper cylinder 310 not to operate; such as: the vibration force generated by the operation of the upper barrel 310 is transmitted to the lower barrel 320 after being damped by the damping suspension spring 50, and the vibration damper 40 connected with the lower barrel 320 plays a role in damping the vibration of the upper barrel 310; the same principle is also true when the upper drum 310 is stopped and the lower drum 320 is operating alone. It should be understood that: the vibration damping suspension spring 50 connected between the upper and lower drums enables the upper and lower drums to play a role of a vibration damper, and the vibration damping effect of the whole washing machine is improved.

Preferably, the extension lines of the two damping suspension springs 50 form an angle range of: 30 degrees or more and 120 degrees or less. When the distance between the upper tube 310 and the lower tube 320 is constant and the angle formed by the extension lines of the two damping suspension springs 50 is large, the two damping suspension springs 50 are connected to the position of the edge of the lower tube 320; when the damping suspension spring 50 is located at the edge of the lower tube, the vibration force transmitted to the upper tube 310 or the lower tube 320 after the vibration force is attenuated by the damping suspension spring 50 is dispersed, that is, the vibration force transmitted to the upper tube 310 or the lower tube 320 is dispersed at the edge of the upper tube 310 or the lower tube 320, so as to improve the attenuation effect of the vibration force. When the angle formed by the extension lines of the two damping suspension springs 50 is small, the two damping suspension springs 50 are connected to the lower cylinder 320 closer to the middle position; when the vibration reduction suspension spring 50 is connected to the middle position of the lower drum 320, the vibration force transmitted to the lower drum 320 is concentrated, and although the vibration force cannot be better dispersed, when the vibration reduction suspension spring 50 is concentrated at the middle position of the lower drum or the upper drum, the vibration reduction suspension spring 50 plays a certain supporting role on the upper drum or the lower drum to reduce the pressure of the connecting piece of the upper drum or the lower drum, namely the hanger rod and the vibration reducer, so as to reduce the pressure when the whole washing machine operates, and prolong the service life of the washing machine.
