Description
Technical Field
The invention relates to a washing machine, in particular to an outer barrel of the washing machine and the washing machine with the outer barrel.
Background
The structure of the existing full-automatic washing machine comprises: a casing forming the appearance of the washing machine; an outer tub suspended and fixed by a support member and containing washing water is provided inside the housing; an inner barrel rotatably installed inside the outer barrel and provided with a stirrer at the bottom thereof; a driving motor installed at the lower side of the outer tub and used for generating driving force of the stirrer and the inner tub; a power transmission device for selectively providing a driving force of the driving motor to the pulsator and the inner tub; and a drainage device installed at the lower part of the outer tub and used for draining the washing water contained in the outer tub to the outside, wherein four hanging lugs are arranged on the outer tub and are hung on the shell through a hanging rod device.
At present, a suspender device comprises a suspender, a suspender seat, a ball seat, a spring and a spring seat, wherein the suspender seat is arranged at the top end of the suspender, the spring seat, the spring and the ball seat sequentially penetrate upwards on the suspender from the bottom end of the suspender, and a friction plate is sleeved in the ball seat; the shell of the washing machine is provided with a spherical groove, and the convex spherical surface of the lifting rod seat is matched with the spherical groove on the shell; the bottom end of the outer barrel is also provided with a spherical groove, and the convex spherical surface of the ball seat is matched with the spherical groove at the bottom end of the outer barrel, so that the outer barrel is hung on the shell of the washing machine.
When the washing machine works, the vibration generated by the outer barrel can cause the ball seat to move up and down, and the ball seat further generates damping force through the expansion and contraction of the spring and the reciprocating friction of the friction plate and the suspender, so that the vibration is inhibited, and the aim of improving the vibration noise level of the whole machine is fulfilled.
However, due to the single spring structure, the change of the elastic coefficient of the suspension rod is small, and the vibration damping effect is lost after the single spring is completely compressed, so that the suspension rod cannot play a good vibration damping effect during washing and dewatering of the washing machine, and the washing machine vibrates greatly and has a large moving distance. In the dehydration transient stage, the internal system vibrates greatly, and a relatively large damping force is required to be provided by the suspender device to inhibit the internal system vibration; during the dehydration steady state phase, the internal system is vibrating less, requiring the boom assembly to provide a relatively small damping force to isolate the vibration.
The traditional washing machine only has four vibration reduction components, and four hanging holes on the box body are distributed on four corners of the washing machine box body. Four hanging holes of the outer barrel are distributed on four corners of the lower part of the outer barrel, and the vibration reduction component can play a role in reducing vibration and noise of the washing machine during dehydration. The vibration reduction and noise reduction effects of the vibration reduction components are not good, and particularly for large-capacity washing machines with the weight of more than 10 kg. The reason is that the large-capacity washing machine has a large quantity of clothes, when the clothes are washed in the inner drum of the washing machine, the clothes are easy to be eccentric, when the clothes in the inner drum are eccentric during the dewatering operation, particularly, the outer drum can swing during the operation, when the eccentric quantity of the clothes is large, the swinging amplitude of the outer drum can be increased, and when the eccentric quantity of the clothes exceeds the self-correction capacity of the washing machine, the washing machine can automatically collide with the stop switch to stop the dewatering operation or collide with the box body, so that abnormal sound is generated.
Many manufacturers have overcome the above-mentioned drawbacks by varying the spring rate of the damping member as follows: 1. the rigidity coefficient of each spring is increased, such as changing materials or thickening the spring, although the vibration reduction effect can be realized during washing and low-speed dehydration, the damping force can not be reduced at high speed, so that the vibration is large, and the normal operation cannot be realized; 2. the length of each spring is increased, and the mode needs to change the height of the outer barrel and the space occupied by the radial direction, thereby increasing the volume of the washing machine.
The present invention has been made in view of this situation.
Disclosure of Invention
The invention aims to overcome the defects of the prior art and provide an outer barrel of a washing machine, which can bear more clothes, reduce the swing amplitude and increase the self-correcting capacity.

Furthermore, the four hanging rod hanging parts are uniformly distributed along the circumference of the outer barrel, and the two hanging rod hanging parts which are oppositely arranged are symmetrically arranged with the center of the outer barrel. The structure is beneficial to the balance of the outer barrel and reduces the swing amplitude of the outer barrel.
Furthermore, the hanger rod hanging part is of a double-hanger-ear structure, or one part of the hanger rod hanging part is of a double-hanger-ear structure, the other part of the hanger rod hanging part is of a single-hanger-ear structure, and the hanger rod hanging part of the single-hanger-ear structure is provided with a hanger.
Furthermore, the hangers comprise a base protruding from the outer wall of the outer barrel and hanger hanging holes arranged on the base, and the hanger hanging holes of the hangers at the hanger hanging part are positioned on the same circumference.
Furthermore, two hangers of the double-hanger structure are of an axisymmetric structure, and the symmetric axis is intersected with the central axis of the outer barrel. The structure is beneficial to the rectification of the outer barrel, effectively decomposes and reduces the swinging force of the outer barrel, so that the outer barrel is more balanced.
Furthermore, two hangers in the hanger hanging part with the double-hanger structure are provided with the same base, and two hanger hanging holes which are arranged in parallel are arranged on the base along the circumferential direction of the outer barrel. This structure has further improved joint strength and damping effect, concentrates the release with the vibration in the same hanging position of outer bucket, can make the big damping force effect of damping performance, effectively reduces the range of swaying of outer bucket.
Furthermore, the hanger rod hanging part and the outer barrel are integrally molded, and at least one reinforcing rib extending along the radial direction of the outer barrel is arranged between two hanger rod hanging holes in the hanger rod hanging part with the double-hanging-lug structure. The reinforcing rib can increase the strength of the hanging part of the hanging rod, can avoid the collision caused by the two vibration reduction parts when the outer barrel swings, and plays a role in guiding in the installation process of the hanging rod.
Furthermore, two suspender hanging holes in the suspender hanging part with the double-lug structure are symmetrically arranged along a reinforcing rib axis.
Furthermore, the number of the hanging lugs on the outer barrel is 5-8, and a hanging rod hanging part with a single hanging lug structure or a double hanging lug structure is formed.
Furthermore, the four hanging rod hanging parts are of a double-hanging-lug structure, the four hanging rod hanging parts are uniformly distributed along the circumference of the outer barrel, two hanging lugs of any hanging rod hanging part are of an axisymmetric structure, and symmetrical axes of the two hanging rod hanging parts arranged at intervals are overlapped.
The washing machine provided by the invention is provided with the outer barrel, and is suspended in a washing machine box body through the suspension rod.
Furthermore, four corners of the upper part of the washing machine box body are respectively provided with support angle plates for hanging the upper ends of the hanging rods, and four groups of hanging rod hanging parts are in one-to-one correspondence with the four support angle plates and are connected through the hanging rods.
Furthermore, the suspender of the suspender hanging part connected with the two hangers comprises a main rod body, a support and two branch rod bodies, the two branch rod bodies are arranged at the lower end of the main rod body in parallel through the support and are connected with the two hangers in a one-to-one correspondence manner, the two branch rod bodies are provided with vibration reduction parts, and the upper end of the main rod body is connected with the supporting angle plate.
Furthermore, the damping resultant force of the damping parts arranged on the two branch rod bodies is the same as the damping part of the hanging part of the single-lug structure hanging rod.
After the technical scheme is adopted, compared with the prior art, the invention has the following beneficial effects.
The invention improves the hanging part structure of the suspender of the outer barrel and increases the hanging position of the suspender, thereby improving the anti-deviation capability of the outer barrel, enhancing the vibration damping effect of the washing machine and realizing high damping and low damping of the washing machine during low-speed operation. At the initial stage of the dewatering operation of the washing machine, especially when the clothes in the inner barrel are eccentric, the outer barrel can swing in the operation process, but the lower part of the outer barrel is provided with the suspension rod hanging part combined with the suspension lugs, so that the swinging force of the outer barrel can be effectively decomposed and reduced, and the swinging amplitude of the outer barrel is reduced, therefore, even when a large amount of clothes are carried, the self-deviation-correcting capability of the washing machine with the outer barrel is effectively improved, and the vibration and the noise are effectively reduced. In the dewatering starting stage, the damping forces of the vibration reduction components can be released in a concentrated mode, the effect of large damping force is exerted, and the swing amplitude of the outer barrel is effectively reduced; in the high-speed stage, the spring coefficient of a single vibration reduction component is small, and the internal vibration is small. Meanwhile, the device has the characteristics of simple structure and convenience in installation.

Preferably, the pressure buffering mechanism comprises an auxiliary spring 73 and a damping spring 74 which are connected in series, when the external force is applied, the branch rod body 53 drives the auxiliary spring 73 and/or the damping spring 74 to do compression movement, when the external force disappears, the auxiliary spring 73 and/or the damping spring 74 do return movement under the action of self elasticity, wherein the elastic coefficient of the auxiliary spring 73 is greater than that of the damping spring 74, when the auxiliary spring 73 is compressed, part or all of the auxiliary spring 73 is compressed into the damping spring 74, so that the volume of the pressure buffering mechanism is reduced, and the length of the shell is reduced.
Further, a damper spring holder 75, an oil-impregnated felt 76, a sliding cup 77, a lower support pad 78, and a seal ring 79 are provided between the damper spring 74 and the bottom cover 72 in this order. The damper spring holder 75 is used to fix the damper spring 74 to prevent the damper spring 74 from being biased by a force, and the felt 76 and the sliding cup 77 are provided to further buffer a rocking force.

The damper spring 74 of the damper member of the present invention is a main spring, and two springs are simultaneously operated before the main spring is pressed. After the main spring is pressed, the auxiliary spring is acted. The series structure increases the load carried by the washing machine, and the phenomenon of sudden change of the total spring coefficient can occur later.
When the water is fed into the washing machine, the auxiliary spring 73 and the damping spring 74 are compressed at the same time, and as the water feeding amount is gradually increased, the damping spring 74 is firstly pressed, and then the auxiliary spring 73 is compressed again until the auxiliary spring 73 is also pressed, so that the effect of hanging and limiting is achieved.
