In the fast-paced modern life, washing machines have long become an indispensable labor helper family. However, the noise and violent vibration it emits often One Hour Photo the tranquility and stability of life. The late-night thumping, dehydration of the huge sound, not only affects our rest, but also may cause damage to the washing machine itself and the surrounding environment. In fact, behind this is a science and technology game about earthquake prevention. Engineers rely on wisdom and innovation, in the structural design, driving mode, material application and other aspects of continuous breakthroughs, so that the washing machine from the source of vibration into a quiet messenger.

(1)、Optimize the structure design

The vibration problem of washing machine often comes from the deviation of the center of gravity or the uneven distribution of mass. Engineers used structural optimizations to make washing machines genetically resistant to vibration from the design stage.

1. Symmetric design

The vibration source of the washing machine (such as motor, inner cylinder) should be as close as possible to the center of mass of the whole machine. Through three-dimensional modeling and dynamic simulation, engineers can accurately calculate the position of the vibration source and the direction of the force, and adjust the layout of the components. For example, by placing the motor directly below the inner cylinder, the centrifugal force offset during rotation can be greatly reduced, so that the vibration energy is scattered along the axis of symmetry rather than concentrated at a certain point.

2. Stiffness control

Traditional washing machine shell using high stiffness metal, vibration directly to the ground. In modern design, the concept of stiffness gradient is introduced: in the critical vibration path (such as the joint between the motor bracket and the shell) , low-stiffness elastic materials are used to form flexible joints; The high-stiffness structure is retained in the position which needs the support strength (such as the bottom frame) . This design can not only ensure the stability of the whole machine, but also effectively attenuate the vibration.

(2)、Equipped with shock absorption system

Shock absorption system is the core defense line of washing machine anti-vibration, through physical damping and energy dissipation, the vibration is strangled in the propagation.

1. Mechanical shock absorber

Three hydraulic dampers are arranged at a 120-degree angle to support the inner cylinder and limit its trajectory. When the inner cylinder rotates eccentrically, the damper produces damping force through the flow of hydraulic oil, and the spring provides the return force, forming a closed loop of absorption-buffer-return.

2. Counterweights

The vibration of the outer cylinder counterweight is suppressed by increasing the moment of inertia. The engineer calculates the maximum eccentric force during dewatering and designs the mass and distribution of the counterweights. An arc-shaped counterweight is installed on the top of the outer cylinder to make the center of gravity of the outer cylinder move downward and form a collision with the upward centrifugal force generated by the rotation of the inner cylinder, thereby reducing the vibration of the whole machine.

(3)、Improve the driving mode

Drive mode directly affects the vibration intensity, engineers through innovative transmission technology, make power transmission more efficient, more quiet.

1. Direct Drive (DD Motor)

DD motor belt with gear removed, motor shaft directly connected to the drum. This design eliminates the traditional transmission system clearance and friction, vibration transmission path is shortened by more than 70% . At the same time, the DD motor adopts vector control technology, which can adjust the torque output in real time, compensate the imbalance of the inner cylinder, and make the dehydration process as smooth as a mirror.

2. Indirect Drive (belt drive)

Belt drives optimize shock absorption by adjusting belt tension and materials such as polyurethane belts. For example, some models use“Wide low tension” belt design, increasing the contact area to disperse stress, while reducing the belt bending stiffness, reducing vibration transmission. With automatic tensioning device, it can always keep the best transmission state.

(4)、The application of damping materials

Advances in materials science have opened up more possibilities for shock absorption.

1. Cushion

The cushion at the bottom of the washing machine is made of composite materials (such as silicone and foam polyurethane) , which can absorb vibration in different frequency bands through a multi-layer structure. The bottom layer of high-density material absorbs low-frequency vibration, the middle layer of elastomer attenuates intermediate frequency jitter, and the surface layer of soft material eliminates high-frequency noise.

2. High performance rubber

High performance rubber is widely used in damping boom, motor bracket and other parts. By optimizing the curing process and the filler ratio, the balance between high damping and high elasticity can be achieved, which can not only support the weight of the motor, but also isolate the vibration transmission.

Conclusion

When we will be washing machine shockproof technology panorama, can not help but be shocked by the power of science and technology. This series of exquisite design and innovation, is not only the crystallization of the wisdom of engineers, but also the perfect integration of technology and life model. It shows us that technology is not some far-fetched theory, but is actually improving our quality of life. With the continuous progress of science and technology, washing machine vibration technology will move towards a new height, for us to bring more quiet, stable washing experience.
