Description of the invention (I) Background of the invention The present invention is more about a washing machine ' That is to say, it is about a ball balancer of a washing machine, which can restrain the unbalanced rotation of the rotating groove and reduce the vibration and noise. Θ There will be an outer slot in the washing machine, which is supported by a suspension device in the shell. There is also a rotating slot 'can hold the laundry and rotate it. The washing machine usually performs the washing, washing and dehydrating operations according to the control program in the controller. When the spin tub is loaded with laundry to perform the spin-drying program, the spin tub will rotate at a high speed, and the washing water will be removed from the laundry by the rotational force of the spin tub. However, improperly placing the rotating groove underwear may cause the rotating groove to rotate in an unbalanced state. This spinning imbalance is particularly serious when the dehydration program is started, and the outer tank supporting the rotary tank will generate vibration and noise. Therefore, it is necessary to install a balancer in the rotating groove to avoid such vibration and noise. According to the various characteristics of washing machines, many different balancers have been proposed. U.S. Patent No. 4,433,592 classifies balancers as liquid balancers, solid state balancers, and ball balancers. Among these balancers, a ball balancer with several balancing balls is widely used and has the best balance effect. FIG. 8 is a diagram illustrating a rotary groove 111 provided with a conventional ball balancer 101. As shown in FIG. In FIG. 8, the conventional ball balancer 101 includes a ring-shaped box 103 with a ring-shaped receiving chamber 105 therein, which is firmly mounted on the top of the rotating groove 111. In the receiving chamber 105 of the ring-shaped box 103, there are several balance beads 107 and mucus 109. The balance beads 107 are made of steel, soaked in sticky (read the first if you read the meaning of the matter on the back, then fill out this page)-installed · II.

Description of the invention (>) 109 in. Both the balance beads 107 and the mucus 109 in the accommodating chamber can be moved circumferentially along the length direction of the accommodating chamber 105. The centrifugal force is generated when the rotation groove 111 rotates, and it is proportional to the square of the rotation groove rotation. Because the center of gravity of the rotation groove 111 is offset from the rotation axis, when the rotation groove 111 rotates, due to the effect of centrifugal force, when the balance bead 107 in the accommodation chamber moves in the accommodation chamber 105, it will be opposite to unbalanced clothes. Weight . Therefore, the balance bead 107 and unbalanced clothes will make the rotation groove 11 丄 reach a balance of 5 so that the vibration of the rotation groove 111 can be suppressed. However, in the conventional ball balancer 101 of a washing machine, when the balance bead 107 in the accommodating chamber 105 is moved in the opposite direction of the weight of the unbalanced clothes by the centrifugal force, the pressure caused by the centrifugal force will be concentrated in the ring box. 103 inner surface of the outer wall. Therefore, over time, the pressure of the balance beads 107 will cause stress on the outer wall of the ring-shaped box 103, causing deformation of the ring-shaped box 103. In addition, because the traditional ball balancer 101 is partly combined with the top edge of the circumference of the rotating groove 111, the outward force of the balancing ball 107, that is, the strong pressure on the outer wall of the ring box 103, is transmitted to the rotating groove. 111, the top surface of the ball groove 101 mounted on the rotating groove 111 is deformed. In particular, if the rotation speed of the rotation tank 111 is increased to enhance the efficiency of dehydration, the top surface of the rotation tank 111 may be damaged by centrifugal force that is proportional to the square of the rotation speed. At this time, the ball balancer 101 is broken, and the balance ball 107 and the mucus 109 leak out. The ball balancer 101 cannot stably provide a balancing function, causing vibration and noise of the rotating groove 111.

Description of the Invention (B) 31 The function is to strengthen the outer wall 15 of the ring box 12 to resist the rotating groove 4 The centrifugal force generated by the balancing beads 33 and the slime 35 during the rotation. With the ball balancer 11 with the above structure, when washing or rinsing, that is, when the rotation of the rotating tank 4 is large or the rotation speed is lower than the resonance rotation speed, each flat-balance ball 3 3 is under the action of mucus viscosity- It will rotate with the rotating groove in a short time. Then, as the rotation groove 4 is gradually accelerated, each balance bead 33 is freely moved in the accommodation chamber 13. g- When dehydrating, the rotating tank 4 rotates at a higher speed than the resonance speed, and the balance bead 33 moves in a direction opposite to the weight of the clothes 39, so that the rotating tank 4 can rotate in a balanced manner. At this time, the centrifugal force generated by the balance beads 33 and the mucus due to the rotation of the rotary groove 4 is applied to the outer wall 15 of the ring-shaped box. However, in this embodiment, since the reinforcing member 31 reinforces the outer wall 15 against centrifugal force, deformation or damage to the top of the outer wall 15 and the rotation groove 4 can be avoided. Various embodiments of the present invention will be described below with reference to Figs. 5, 6, and 7. In these figures, the same reference numerals denote the same elements as those in Figs. 1 to 3, respectively.

Description of the invention (7), Figure 6 shows the ball balancer of the third embodiment of the present invention 51 includes the same cymbal elements of FIGS. 1 to 3, but the reinforcing member 31 is located inside the outer wall 15 of the ring box 12. After the top cover 21 of the ring-shaped box 12 is opened, the reinforcing member 31 can be easily inserted into the outer wall 15. In FIG. 7, a ball balancer 61 according to a fourth embodiment of the present invention includes a pair of ring-shaped boxes 12, each of which is substantially the same in structure, and is connected together in a coaxial manner in a vertical manner, which is one of them. Stacked on top of one another. In the pair of ring-shaped boxes 12, each of the accommodating chambers 13 has a balance bead 33 and a slime 35 in order to maintain the rotational balance of the rotary slot 4. Inside the inner wall 15 of each ring box 12, there is a reinforcing member 31. With the ball balancer 61 having the above structure, when the rotation groove 4 rotates unbalanced, the rotation radii of the ring boxes 12 are different from each other, so the upper and lower balance balls 33 in the two ring boxes 12 will move independently. . That is, the upper and lower balance beads 33 are independently moved according to the weight of the laundry 39 and the rotation speed of the rotation tank 4, so that the rotation balance of the rotation tank 4 can be maintained more effectively. Both the reinforcing components 31 can resist the centrifugal force generated by the balancing beads 33 and the mucus 35 when the rotary groove 4 rotates, so as to prevent the ring-shaped box 12 and the rotary groove 4 from being deformed or damaged. Although the pair of ring-shaped boxes 12 in the fourth embodiment are arranged vertically, they may be arranged horizontally, that is, arranged horizontally. If so arranged, the reinforcing members 31 are preferably divided into the outer walls 15 of the respective ring-shaped boxes 12. In addition, two or more ring-shaped boxes 12 having substantially the same structure may be adopted according to the characteristics and capacity of the washing machine, and may be arranged and installed in a vertical or horizontal manner. 10 This paper size applies the Chinese National Standard (CNS) A4 specification (210X297 mm) am a · — Bn.— m \ In In I /!., (Please read the precautions on the back before filling this page) Order 4 lines _ A7 B7 1787PIF.DOC / whyW / 005 V. Description of the invention (2) Although the reinforcing components 31 are manufactured separately in the first, third and fourth embodiments, the reinforcing components 31 may also be combined with the ring box 12-body molding. As explained above, in the ball balancer of the washing machine of the present invention, a reinforcing component is installed immediately on the outer wall of the ring-shaped box that contains the balancing beads and the mucus. When the rotating groove rotates, the ring-shaped box and the rotating groove can be saved. Affected by the centrifugal force of the balancing beads and mucus, the ring box and the rotating groove are protected from deformation and damage. Therefore, the life of the ring box and the rotating groove can be improved, and even after a period of time, the ball balancer can stably provide a balancing function to avoid vibration and noise. -------- Installation ------- Order ----- line (please read the precautions on the back before filling this page), the consumer cooperation of the Central Standards Bureau of the Ministry of Economic Affairs Moderate County
