Description of the Invention (I) The present invention relates to a washing machine, and in particular to an effective reduction of vibration And noisy washing machines. This washing machine includes an External Cabinet, an Outer Tub inside the outer box, a Spin Basket that can rotate inside the outer slot, and a number of outer slots in the hanging outer box. Suspension Unit. A general washing machine generally includes an outer box and a vibration system composed of an outer tank and a rotating basket suspended in the outer box. Among them, the rotatable rotating basket device for holding clothes is in the outer tank, and the outer tank containing the rotating basket is suspended in the outer box by some suspension units. During the washing, washing and dehydrating process, the washing machine will vibrate due to the rotation of the rotating basket. This vibration is particularly severe when the laundry in the rotating basket is not balanced. The vibration of the rotating basket will be transmitted to the outer tank, so that the outer tank will generate vibration and noise. Therefore, the suspension unit of the washing machine is usually equipped with a damper (Damper) to reduce the vibration of the outer tank. FIG. 1 illustrates a conventional washing machine structure. The figure includes an outer tank 4 and a vibration system 3 of a rotating basket 5. The suspension unit 61 is installed at each corner of the outer box 2 to extend and retract. Suspended in the outer box. A vibrator (Pulsator, not shown) is installed in the rotating basket 5 to rotate the water flow. Below the vibration system 3, a power transmission unit 9 having a drive motor (not shown in the figure) and a transmission assembly (not shown in the figure) is used to rotate the rotating basket or the vibrator. The operation of the drive motor is controlled by a program stored in the controller for washing, washing, and dehydrating actions. As shown in Figure 丨, the traditional suspension unit 61 includes a suspension rod 63 connecting the outer groove 4 and the outer box 2 and 4 to the rear end of the suspension rod 63 of the outer groove 4 to support the paper.

Description of the invention (z) Shock absorber 65. This shock absorber 65 contains a hollow cylindrical tube (not shown) (In the figure) and a piston that can slide and rub in a cylindrical cylinder, this piston is connected to the bottom end of the boom 63. In the upper part of the rotating basket 5, a balancer 6 is installed to balance the rotating basket 5 Rotation. In the above structure, when the vibration system vibrates, that is, when the rotating basket rotates to cause the vibration of the outer tank 4, the piston slides up and down in the cylinder, so the vibration transmitted to the outer tank is caused by the cylinder and the piston. The frictional force is reduced. The vibration generated by the vibration system and its cause are shown in Figure 2. Vibration The vibration generated by the system can be divided into a translational motion and a rotational motion. The translational motion includes components in the X-, Y-, and Z-directions, and the rotational motion includes the pitch on the X-axis (Pitching, P ), The Y-axis offset (Yawing, Y), and the Z-axis scroll (Rolling, R). · The translation component in the Z-direction, and the Z-axis scroll (R) are operations. The basic motion elements of the vibration system 3 can be omitted here. In addition, the translation components in the Y- and Z- directions, as well as the pitch (P) and offset (Y) in the Y- and Z-axis are unnecessary. The motion element, which will generate noise and affect the durability of the washing machine. The vibration generated by the vibration system 3 can be divided into two stages, the first stage is the initial stage of the dehydration process, and the second stage is the time of washing Intermittent dehydration process. The vibration produced in the initial stage of the dehydration process is translational motion, and the vibration produced by the intermittent dehydration process is rotational motion. The natural frequencies of the translational motion and rotational motion generated by the vibration system are 丨 .7Hz ( 102rPm) and 4.5Hz (270rpm). In the initial stage of the dehydration process' The vibration is caused by the unbalanced rotation of the rotating blue 5. That is, when the laundry load 5 inside the rotating basket 5 (谙 first read the precautions on the back before filling this page)-Binding and binding paper size Applicable to China National Standard (CNS) A4 specification (210X297 mm) 1 8 1 2twf / Jessie / 002 A7 B7 Printed by the Consumer Cooperatives of the Central Standards Bureau of the Ministry of Economic Affairs 5. Description of invention (Even) When the balance is imbalance, the rotating basket 5 will be In an unbalanced state, it rotates below the range of 1.7 Hz. At this time, the balance ball and a viscous liquid (not shown) in the balancer 6 may not move toward the unbalanced load of the laundry. Therefore, due to the unbalanced rotation of the rotating basket, its noise increases. On the other hand, in the intermittent dehydration process, when the rotation frequency of the rotating basket 5 is greater than 1.7 Hz, the balance ball and the viscous liquid begin to move, and at a frequency of 4.5 Hz, the amplitude of the vibration depends on the balance ball and the viscosity The location of the liquid. For example, when the movement of the balance ball and the viscous liquid has nothing to do with the rotating basket 5, and its position is on the same side as the unbalanced clothes, the vibration becomes severe. The vibration transmitted from the rotating basket 5 to the outer tank 4 is reduced by the presence of the suspension unit 61. However, the conventional suspension unit 61 is obtained based on the experimental results of the washing machine 60 under no-load conditions. Therefore, the vibration system 3, that is, the translational and rotational movements transmitted to the outer tank by the rotating basket 5, cannot properly reduce and generate noise. At the same time, during normal operation, the vibration system 3 will collide with the outer box and cause damage to the washing machine parts. The main object of the present invention is to provide a washing machine whose washing, washing and dehydrating functions can be operated in a range lower than the natural frequency of the outer tank, thereby effectively reducing the vibration of the outer tank and the noise of the washing machine. According to the above object, the present invention provides a washing machine including an outer box, an outer tank installed in the outer box, a rotating basket installed in the outer tank, and a plurality of suspension units supporting the outer tank.

Because the outer groove 4 and the rotating basket 5 are cylindrical, the outer box is approximately a long cylindrical shape. There are several holes in the wall of the rotating basket 5 to allow washing water to flow between the rotating basket 5 and the outer tub 4. An annular ball balancer 6 is mounted on the upper half of the rotating basket 5. The ring-shaped ball balancing device includes a plurality of balancing balls 55 and a viscous liquid 53, which are arranged in a ring-shaped container 53. The function of the balance ball 55 and the viscous liquid 53 is to rotate the balance basket 5. As shown in FIG. 1, a vibrator 51 is installed at the bottom of the rotating basket 5 to generate a vortex of washing water. The vibration system 3 is supported by a plurality of suspension units, and is suspended in the outer case 2 in a telescopic manner. The preferred number of suspension units is eight, that is, four pairs, and the position of each pair is at each corner of the outer box 2. A power transmission unit 9 is provided with a drive motor 7 and a transmission assembly 8 which are fixedly arranged below the outer groove 4 'and surrounded by a base (not shown).

Description of the invention (1) End to control the boom 13. The shaft of the boom 13 penetrates the cylindrical cylinder Π, the piston 19, and the neck-like member 18, and the piston 19 can move up and down inside the cylindrical cylinder 17. A buffer spring 20 is interposed between the cylinder π and the piston 19 to elastically push the piston 19 downward. A spring bracket 2 and a washer 22 are installed between the buffer spring 20 and the blocking member 14. The shock absorber 15 is composed of a combination of a neck-shaped member 18 and a handle 10 in the outer groove 4, and the boom 13 is connected to the upper half of the inner wall of the outer box 2 (not shown in the figure), and the outer groove is thus combined. The structure is suspended in the outer box 2. In the washing machine with the above structure, the vibration of the vibration system, that is, the displacement components in the X-, Y- directions, and the pitch and offset of the X-axis and Y-axis (see Figure 2) ' Very severe, the paired structure of suspension units can be reduced. At this time, the vibration is reduced by the abrasive contact between the piston 19 and the cylindrical cylinder 17 and the damping action of the spring 20. According to this embodiment, the number of the suspension units 11 is larger than that of the conventional washing machine 60, and the elastic coefficient of the buffer spring can be reduced to improve the buffer function. For example, when the spring elastic coefficient of the suspension unit of the conventional washing machine 61 with a capacity of 8 kg is 0.3 kgf / mm or more, in the washing machine of this embodiment, the elastic coefficient of the buffer spring 20 of the suspension unit 11 can be reduced to 0.15 kgf / mm, which is half of the former. Therefore, due to the improvement of the buffer function of the buffer spring 20, the washing function of the washing machine is also improved accordingly. The vibration suppression effect of this embodiment is shown in FIG. 6. According to the present embodiment, the vibration amplitude of the washing machine 1 at the initial stage of dehydration is about half that of the conventional washing machine 61. In the following, the embodiments according to the present invention will refer to Figure 1 and Figure 8.

Referring to Fig. 7, the washing machine 30 according to the second embodiment includes the same components as those of the washing machine 1 according to the first embodiment in Figs. 3 and 4. However, compared with the suspension unit 11 in Figs. 3 and 4, the suspension unit 31 has been modified. That is, the suspension unit 31 in this embodiment has a single boom 13 and a pair of shock absorbers 15. At the lower end of the boom 13, there is a T-shaped joint 33 'which has two opposite forks' as shown in FIG. A pair of time-shaped rods 35 are installed at the joints with two forks, respectively. The 33 ° shock absorber 15 merges with the lower end of the elbow rod, respectively. Fig. 9 explains the initial stages of the dehydration operation of Fig. 7 and the conventional washing machine, respectively. As shown in FIG. 9, the vibration amplitude of the washing machine 30 mentioned in this embodiment is about half that of the conventional washing machine. Therefore, 'the elastic coefficient of the spring 20 of the suspension unit in this embodiment can be reduced to half that of the first embodiment. As shown in Fig. 7, 'the boom 13 and the elbow rod 35 that is combined with the handle 10 and the outer tank have a three-point support structure', so it can effectively prevent the vibration system 3 during laundry, washing and dehydration operations. Torque of the outer groove caused by the inertia. _-According to the embodiment Γ, in the washing machine, 'two shock absorbers are installed in parallel, however, according to different washing machine characteristics and different capacities', three or more shock absorbers may be used, and the plurality of shock absorbers Can be installed in series. In this embodiment, the elbow cymbal 35 is connected to the boom 13 via a T-shaped coupler 33. However, the elbow rod 35 and the boom 13 can be integrally formed to simplify the structure of the suspension unit 31.
