The stability of the laundry treating apparatus is greatly improved by the cooperation of the first damper 12 and the second damper 13.
Referring further to fig. 2, the vibration damping system 1 for a laundry treating apparatus of the present invention will be described in detail.
As shown in fig. 2, in a possible embodiment, the first damper 12 and the second damper 13 include a sleeve 121 and a plunger 122, the plunger 122 is sleeved in the sleeve 121 and can move up and down along the axis of the sleeve 121, the support portion 11 includes a plurality of fixing brackets, each of the fixing brackets is correspondingly provided with one first damper 12, one second damper 13 and one elastic member 14, and the elastic member 14 is preferably a spring, and may be a plate spring, an elastic washer or the like. A stop ring 15 is also fixedly connected to the first damper 12, one end of the spring abuts against the stop ring 15, and the other end abuts against the bottom plate 2, so that the spring is confined between the stop ring 15 and the bottom plate 2. A vibration sensor (not shown) is further provided on the first damper 12, and the vibration sensor is connected to an alarm system (not shown) of the laundry treating apparatus. The axes of the first damper 12 and the second damper 13 are both at an angle to the vertical, i.e. neither damper is arranged vertically, but at an angle offset with respect to the vertical, and the axis of the first damper 12 and the vertical passing through the first damper 12 form a first plane, the axis of the second damper 13 and the vertical passing through the second damper 13 form a second plane, and the first plane and the second plane are perpendicular, i.e. the first damper 12 and the second damper 13 are deflected on two mutually perpendicular planes. Referring to fig. 1, the first damper 12 is disposed to be outwardly biased with respect to the outer tub 3 in a radial direction of the outer tub 3, and the second damper 13 is disposed to be outwardly biased with respect to the washing tub in an axial direction of the outer tub 3. A third damper 16 is further arranged between the first damper 12 and the outer cylinder 3 along the vertical direction, one end of the third damper 16 is hinged with the first damper 12, and the other end is hinged with the lower part of the outer cylinder 3.

The vibration sensor is additionally arranged, so that the vibration state of the clothes treatment equipment can be monitored, and the product is safer. The first damper 12 and the second damper 13 deflect on two mutually perpendicular planes, so that vibration damping consumption of the outer cylinder 3 in all directions is more effectively realized, and the amplitude and vibration noise of the outer cylinder 3 are reduced. The addition of the third damper 16 makes the damping effect of the damping system 1 more stable. The motor 4 is disposed at a position to make the upper space of the outer tub 3 larger. The multi-point support improves the integrity and stability of the damping system 1. Providing the support portion 11 separately without injection molding the support portion 11 directly on the outer cylinder 3 makes the shock absorbing system 1 easier to install.
It should be noted that the above-mentioned embodiments are only used for illustrating the principle of the present invention, and are not intended to limit the protection scope of the present invention, and those skilled in the art can modify the above-mentioned structure so that the present invention can be applied to more specific application scenarios without departing from the principle of the present invention.
