The shock absorption system 1 includes a support part 11 , a first damper 12 , a second damper 13 and an elastic member 14 , the support part 11 is fixedly connected to the lower part of the outer cylinder 3 , and one end of the first damper 12 is pivotally connected to the bottom plate 2 , The other end is hinged with the support part 11 (the connection mode of the hinged connection and the pivotal connection is a conventional connection mode in the field, so it is only described, but not specifically shown in the figure, the same below). The elastic member 14 is sleeved on the first damper 12 and abuts the first damper 12 and the bottom plate 2 at both ends respectively.

The advantage of the above arrangement is that: after the original elastic member 14 on the upper part of the outer cylinder 3 is adjusted to the lower part to be combined with the first damper 12, the upper part of the outer cylinder 3 is vacated, which can be convenient for designers to continue to add new clothes to the clothes treatment equipment. It can enrich the functions of laundry treatment equipment, such as water mist care generator module, aroma enhancement module, etc., and can also increase the size of the detergent storage box. Through the cooperative use of the first damper 12 and the second damper 13, the stability of the laundry treatment apparatus is greatly improved.

2 , the damping system 1 for a laundry treating apparatus of the present invention will be described in detail below.

As shown in FIG. 2 , in a possible implementation manner, the first damper 12 and the second damper 13 include a sleeve 121 and a plunger 122 , and the plunger 122 is sleeved in the sleeve 121 and can move along the sleeve The axis of 121 moves up and down, and the support portion 11 includes a plurality of fixed brackets, each of which is correspondingly provided with a first damper 12, a second damper 13 and an elastic member 14, and the elastic member 14 is preferably a spring, It can also be a leaf 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 is in contact with the stop ring 15 , and the other end is in contact with the bottom plate 2 , so that the spring is restricted between the stop ring 15 and the bottom plate 2 . A shock sensor (not shown in the figure) is also provided on the first damper 12, and the shock sensor is connected with an alarm system (not shown in the figure) of the laundry treatment apparatus. The axes of the first damper 12 and the second damper 13 both have an included angle with the vertical line, that is, the two dampers are not arranged vertically, but have a certain deflection angle with respect to the vertical line, and the first damper The axis of the damper 12 and the vertical line passing through the first damper 12 form a first plane, the axis of the second damper 13 and the vertical line passing through the second damper 13 form a second plane, and the first plane and the first plane The two planes are perpendicular, that is, the first damper 12 and the second damper 13 are deflected on two mutually perpendicular planes. 1 , the first damper 12 is deflected outward relative to the outer tub 3 along the radial direction of the outer tub 3 , and the second damper 13 is deflected outward relative to the washing tub along the axial direction of the outer tub 3 . A third damper 16 is also arranged vertically between the first damper 12 and the outer cylinder 3 . 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 advantage of the above arrangement is that: through the arrangement of the sleeve 121, the plunger 122 and the arrangement of the spring between the stop ring 15 and the bottom plate 2, the first damper 12 can also buffer the force transmitted by the outer cylinder 3. With the effect of restoring the damping system 1 to the initial state, the first damper 12 is connected to the spring, which also makes the damping system 1 more rigid and less prone to shaking, and can achieve stable operation under larger eccentricity. The spring also has the function of vibration energy storage, and the stored energy can be used to resist the force transmitted from the outer cylinder 3 again. A vibration sensor is added on the first damper 12 and connected to the alarm system. When the vibration is within the normal range, the alarm system will not alarm. Due to excessive vibration, other parts will be damaged and the service life of the equipment will be reduced. The first damper 12 and the second damper 13 are not arranged vertically, and the two dampers are deflected on two mutually perpendicular planes, so that the shock absorption system 1 can absorb the forces in all directions more effectively. The direction and magnitude of the acting force of the outer cylinder 3 are not static, but random, which makes the damping system 1 must have the ability to buffer the acting force in all directions. The present invention makes the first damper 12 and the second The deflection direction of the damper 13 is vertical and not vertically arranged, which can balance the buffer capacity in all directions to the greatest extent and reduce the amplitude and vibration noise of the outer cylinder 3 . A third damper 16 is arranged between the first damper 12 and the lower part of the outer cylinder 3 , which can further enhance the shock absorption capability of the damping system 1 and avoid the first damper 12 caused by the excessive rotation of the outer cylinder 3 . The situation occurs where the second damper 13 is insufficient to resist the eccentricity, which eventually destroys the damping system 1 .

In particular, the motor 4 of the present invention is arranged on the center line of the outer cylinder 3, and also does not occupy the upper space of the outer cylinder 3, so that the upper space of the outer cylinder 3 is larger, which is more conducive to the release of the upper space. The present invention improves the integrity of the shock absorbing system 1 through the connection of a plurality of fixing brackets, and separates the supporting portion 11 and the outer cylinder 3 for processing by separately setting the supporting portion 11, thereby reducing the processing cost, and the shock absorbing system can be installed during installation. The system 1 is installed first, and then the whole is connected with the outer cylinder 3, which is more convenient for installation.

To sum up, in the present invention, by arranging the spring at the lower part of the outer cylinder 3, and sleeved with the first damper 12, and abutting between the stop ring 15 and the bottom plate 2, the upper space of the outer cylinder 3 is released, and the space in the upper part of the outer cylinder 3 is released. The stiffness of the shock absorption system 1 is increased, it is more difficult to shake, realizes stable operation with large eccentricity, and can also store energy to resist the force transmitted from the outer cylinder 3 again. Adding a vibration sensor can monitor the vibration state of the laundry treatment equipment, making the product safer. The first damper 12 and the second damper 13 are deflected on two mutually perpendicular planes, which more effectively realizes the vibration damping consumption of the outer cylinder 3 in all directions, and reduces the amplitude and vibration noise of the outer cylinder 3 . The addition of the third damper 16 makes the damping effect of the damping system 1 more stable. The installation position of the motor 4 makes the upper space of the outer cylinder 3 larger. The multi-point support improves the integrity and stability of the shock absorption system 1 . The supporting portion 11 is provided separately without directly injection molding the supporting portion 11 on the outer cylinder 3 , so that the damping system 1 is easier to install.

Those skilled in the art can adjust the above structures without departing from the principles of the present invention, so as to The present invention can be applied to more specific application scenarios.

For example, in an alternative embodiment, the support portion 11 can also be an integral bracket instead of a plurality of smaller fixed brackets, which is more convenient for installation and can also achieve the same shock absorption effect. The installation of the second damper 13 and the like will not be affected. This solution does not deviate from the principle of the present invention, and therefore falls within the protection scope of the present invention.

For example, in another alternative embodiment, the type of the damper is not limited. For example, the damper in the present invention is preferably a pneumatic damper, but obviously it can also be replaced by a hydraulic damper, a friction damper, etc. None of them deviate from the principles of the present invention, and therefore all fall within the protection scope of the present invention.

For example, in another alternative embodiment, the first damper 12 , the second damper 13 and the third damper 16 may also be connecting rods with certain elasticity and rigidity, as long as the function of the outer cylinder 3 can be buffered The force is sufficient, all of which do not deviate from the principle of the present invention, and therefore all fall within the protection scope of the present invention.

In addition, the present invention also provides a drum washing machine, which has the damping system 1 described in any one of the above embodiments.
