Description

Technical Field

[0001] The invention belongs to the field of household appliances, and in particular relates to a washing machine. Background Art

[0002] Existing washing machines, such as Figure 1 As shown, the structure of a washing machine generally includes two parts, an inner barrel 1' and an outer barrel 2'. The inner barrel 1' and the outer barrel 2' are connected, a dehydration port is provided on the inner barrel 1' for dehydration, and the outer barrel 2' is closed as a water storage barrel. In this way, when the washing machine is working, the area between the inner barrel 1' and the outer barrel 2' is full of water. During the long-term use and operation of the washing machine, the area between the inner barrel 1' and the outer barrel 2' will be covered with dirt and thread scraps in the water. Bacteria and odor will be generated over the years, which will have a great impact on the washing effect and user experience.

[0003] In addition, the impeller 3' and the inner barrel bottom 4' of the existing fully automatic impeller washing machine are driven by different driving shafts, and the impeller 3' is rotatable relative to the inner barrel bottom 4'. Therefore, there is a gap between the impeller 3' and the inner barrel bottom 4'. In addition, the bottom of the impeller 3' generally has more reinforcing ribs. As the washing machine is used for a longer time, dirt and grime are easily hidden between the impeller 3' and the inner barrel bottom 4', which eventually leads to secondary contamination of the washed clothes.

[0004] In order to solve the problem of secondary pollution of washed clothes caused by water filling the space between the inner barrel and the outer barrel, existing manufacturers have developed a new type of washing machine that can seal the inner barrel, and there is no water between the inner barrel and the outer barrel to prevent pollution. Known solutions include designing the inner barrel as a hole-free inner barrel, so that the inner barrel and the outer barrel are isolated, and the inner barrel acts as a water bucket. At the same time, in order to drain the inner barrel, the centrifugal force generated by driving the inner barrel to rotate at a relatively high speed is used to make the water in the inner barrel be thrown out from the dehydration port at the upper end of the inner barrel, or through an external sealing structure, it is pressed against the drainage port at the bottom of the inner barrel to achieve the sealing of the inner barrel. Although the hole-free inner barrel can solve the problem of dirt between the inner barrel and the outer barrel, it cannot solve the problem of dirt between the impeller and the bottom of the inner barrel.

[0005] Therefore, the present invention is mainly intended to solve the problem of dirt hiding between the impeller and the bottom of the inner barrel of a fully automatic impeller washing machine. Furthermore, combined with the self-cleaning solution of the hole-free inner barrel, the washing machine can be fully self-cleaned to eliminate dead corners for dirt. However, when washing, a washing machine with such a structure accelerates quickly because the motor directly drives the entire inner barrel component and the laundry and water in the barrel to run together, and the momentum of the inner barrel component and the laundry and water in the barrel is relatively large. According to the law of action and reaction, the reaction momentum formed by the outer barrel component is also relatively large. The existing shock-absorbing device cannot solve the vibration caused by the reaction momentum of the outer barrel component. The outer barrel component moves significantly inside the washing machine body, causing the problem of hitting the body, thereby causing abnormal noise.

[0006] In view of this, the present invention is proposed. Summary of the invention

[0007] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a washing machine which can avoid secondary pollution, has good washing effect and low noise.

[0020] A further solution is that the shock absorbing device includes a suspension shock absorbing member and a support shock absorbing member, the suspension shock absorbing member suspends the water receiving bucket in the shell, and the support shock absorbing member supports the water receiving bucket;

[0021] Preferably, the suspension shock absorber and / or the support shock absorber are symmetrically arranged with the central axis of the water receiving bucket as the center;

[0022] Preferably, the number of the suspension shock-absorbing components and the number of the supporting shock-absorbing components are 2-4 respectively.

[0023] A further solution is that one end of the suspension damping member is connected to the upper part of the shell, and the other end is connected to the suspension mounting seat of the water receiving bucket, and the suspension mounting seat is arranged on the peripheral wall of the water receiving bucket;

[0024] Preferably, the height of the suspension mounting seat is not lower than the horizontal height of the bottom of the washing tub;

[0025] Preferably, the extension line of the suspension shock absorber intersects with the central axis of the water receiving bucket.

[0026] A further solution is that the lower end of the support shock absorber is hingedly connected to the lower part of the shell, and the upper end is hingedly connected to the bottom or peripheral wall of the water receiving bucket, and the support shock absorber is inclined from bottom to top along the radial direction of the water receiving bucket;

[0027] Preferably, both ends of the supporting shock-absorbing member are connected to the housing and the water receiving bucket respectively through universal connectors.

[0028] A further solution is that there are four suspension damping components and four supporting damping components respectively, and the suspension damping components and the supporting damping components correspond to each other to form a group, and each group is arranged at the corners of two adjacent side walls of the shell.

[0029] Alternatively, a further alternative is that the number of the suspension damping member and the number of the support damping member are two, respectively, and each is arranged at a corner of two adjacent side walls of the shell;

[0030] Preferably, the suspension shock-absorbing components and the supporting shock-absorbing components are distributed at intervals along the outer circumference of the water receiving bucket.

[0031] Further, an alternative to the above solution is that the lower end of the support shock absorber is hingedly connected to the lower part of the shell, and the upper end is hingedly connected to the bottom or peripheral wall of the water receiving bucket, and the support shock absorber is inclined from bottom to top along the tangent direction of the water receiving bucket;

[0032] Preferably, there are four suspension dampers and four supporting dampers, and the suspension dampers are arranged at the corners of two adjacent side walls of the shell. The suspension dampers and the supporting dampers are distributed at intervals along the outer circumference of the water receiving bucket.

[0033] Preferably, both ends of the supporting shock-absorbing member are connected to the housing and the water receiving bucket respectively through universal connectors.

[0034] A further solution is that the supporting shock absorbing member includes:

[0035] Two sleeves, each sleeve defines a receiving cavity, has an opening at one end and is closed at the other end, the closed end of one sleeve is connected to the base of the shell, and the closed end of the other sleeve is connected to the peripheral wall or bottom wall of the water receiving bucket;

[0036] The piston rod is movably connected to the sleeve, and its two ends are respectively extended into the two sleeve openings in a one-to-one correspondence and are slidably arranged in the accommodating cavity of the sleeve.

[0037] The washing machine of the present invention controls the driving motor to drive the washing tub to rotate forward and reverse at a set washing speed during the washing process, and controls the driving motor to drive the washing tub to rotate unidirectionally at a set dehydration speed during the dehydration process.

[0038] After adopting the above technical scheme, the present invention has the following beneficial effects compared with the prior art.

[0039] The washing machine washing tub of the present invention has a closed barrel body design so that the washing tub can independently hold washing water during washing / rinsing, thereby avoiding water accumulation between the washing tub and the water receiving tub, and solving the problem of secondary pollution caused by dirt and grime between the washing tub and the water receiving tub.

[0040] The washing machine washing drum of the present invention eliminates the impeller that can rotate relative to the washing drum, and instead has a washing portion that is sealed and assembled on the inner surface of the bottom of the drum or is integrally formed with the washing portion that protrudes toward the inside of the washing drum. During washing, the washing drum rotates to drive the washing portion at the bottom of the drum to drive the water flow and the clothes to move. The washing portion is used to break the stationary state of the water flow when the washing drum starts to rotate and the rotational inertia state when it stops, so that the water flow collides and rubs against the clothes to achieve washing, thereby ensuring the washing effect.

[0041] The water receiving bucket of the present invention is suspended and supported in the shell by a shock absorbing device, and the suspension shock absorbing component and the supporting shock absorbing component cooperate to reduce shock, thereby eliminating the reaction momentum formed by the water receiving bucket component and avoiding collision with the housing, thereby greatly reducing the vibration during the operation of the washing machine, greatly weakening the vibration noise, and achieving a silent washing effect.

DETAILED DESCRIPTION

[0051] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention but are not used to limit the scope of the present invention.

[0052] In the description of the present invention, it should be noted that the directions or positional relationships indicated by terms such as “upper”, “lower”, “front”, “back”, “left”, “right”, “vertical”, “inside” and “outside” are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0053] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0054] like Figure 2 As shown, a washing machine described in the present invention includes a shell 1, a washing tub 2, a water receiving tub 3, a shock absorbing device and a driving motor 7. The washing tub 2 is a water receiving tub structure, which is rotatably arranged in the shell, has a clothing taking-in and putting-out opening at the upper part, and has a washing part protruding from the inner surface of the bottom of the tub and rotating integrally with the washing tub 2 at the lower part; the water receiving tub 3 is arranged outside the washing tub 2, at least a part of which is arranged below the washing tub 2 to support the washing tub 2; the shock absorbing device connects the water receiving tub 3 and the shell 1, and the water receiving tub 3 is suspended and supported in the shell 1 through the shock absorbing device; the driving motor 7 directly or indirectly drives the washing tub 2 to rotate.

[0055] Embodiment 1

[0056] like Figure 2 As shown, the washing tub 2 described in this embodiment includes a tub bottom 5 and a tub body 4, wherein the tub body 4 has a closed area, and the closed area and the tub bottom 5 together form a water holding chamber that can independently hold washing water, and the inner surface of the tub bottom 5 is sealed or integrally formed with a tub bottom washing portion 9 that protrudes toward the interior of the washing tub 2, and / or the inner surface of the tub body 4 is sealed or integrally formed with a tub body washing portion 8 that protrudes toward the interior of the washing tub 2.

[0057] The washing tub 2 of the washing machine of this embodiment and the closed design of the barrel body 4 enable the washing tub 2 to independently hold washing water during washing / rinsing, thereby avoiding water accumulation between the washing tub 2 and the water receiving tub 3, and solving the problem of dirt and grime accumulating between the washing tub 2 and the water receiving tub 3.

[0058] In addition, the washing tub 2 of the washing machine of the present embodiment cancels the impeller that can rotate relative to the washing tub, and instead seals or integrally forms a bottom washing portion 9 protruding toward the inside of the washing tub 2 on the inner surface of the bottom 5 of the barrel, and / or seals or integrally forms a barrel washing portion 8 protruding toward the inside of the washing tub 2 on the inner surface of the barrel body 4. When washing, the bottom washing portion 9 and / or the barrel washing portion 8 are driven by the rotation of the washing tub 2 to drive the water flow and the clothes to move with it, so as to achieve washing / rinsing. The washing tub 2 of the washing machine of the present embodiment cancels the impeller by seals or integrally forming a bottom washing portion 9 protruding toward the inside of the washing tub 2 on the inner surface of the bottom 5 of the barrel, and / or seals or integrally forming a barrel washing portion 8 protruding toward the inside of the washing tub 2 on the inner surface of the barrel body 4, thereby solving the problem of easy dirt hiding between the impeller and the bottom 5 of the barrel, and driving the water flow and the clothes to move with it by the bottom washing portion 9 and / or the barrel washing portion 8 to achieve washing / rinsing, thereby ensuring the washing effect.

[0059] The bottom washing part 9 on the bottom 5 of the barrel in this embodiment can be a separate component, but needs to be in sealed contact with the bottom 5 to prevent washing water from entering therebetween, or can be formed integrally with the bottom 5. Preferably, the washing part is a reinforcing rib integrally stamped on the bottom 5 of the washing barrel to enhance the strength of the bottom 5.

[0060] Similarly, the barrel washing part 8 on the barrel 4 described in this embodiment can be a separate component, but it needs to be in sealed contact with the barrel 4 to prevent washing water from entering between the two, and can also be formed as an integral part of the barrel 4.

[0061] The bottom washing part 9 of the present embodiment is mainly used to realize the up and down rolling of the washing water, driving the up and down movement of the clothes, and the barrel washing part 8 is mainly used to realize the circumferential rolling of the washing water, driving the circumferential movement of the clothes. The bottom washing part 9 and the barrel washing part 8 of the present embodiment can be set at the same time or one of them can be set selectively. Preferably, the bottom washing part 9 and the barrel washing part 8 are simultaneously set in the washing barrel 2 of the washing machine of the present embodiment to enrich the water flow and improve the washing effect.

[0062] Embodiment 2

[0063] like Figure 3 As shown, the barrel bottom washing part 9 of this embodiment includes at least two ribs 17 radially distributed on the inner surface of the barrel bottom 5, and the bottom ends of the ribs 17 are sealed and connected to the inner surface of the barrel bottom 5;

[0064] Preferably, the rib 17 extends from the center of the washing tub bottom 5 to the periphery;

[0065] Preferably, the number of the convex ribs 17 is 2-10, and in this embodiment, the number of the convex ribs 17 is preferably 2.

[0066] It is also preferred that one end of the convex rib 17 away from the center of the washing tub bottom 5 extends to the peripheral wall of the washing tub body 4 (not shown in the figure).

[0067] A further solution is that at least one of the water-facing surfaces of the convex ribs on both sides of the extending direction smoothly transitions with the inner surface of the barrel bottom;

[0068] Preferably, the water-facing surface includes at least one steep slope surface in the extending direction of the convex rib, and the steep slope surface and the inner surface of the barrel bottom have an angle of inclination of no more than 100°;

[0069] Preferably, the steep slope surface is provided at one end of the convex rib close to the peripheral wall of the washing tub.

[0070] Specifically, this embodiment arranges convex ribs, water-facing surfaces and steep slopes so that during the washing process, the washing tub rotates to drive the washing part at the bottom of the tub to drive the water flow and the clothes to move. The washing part is used to break the stationary state of the water flow when the washing tub starts to rotate and the rotational inertia state when it stops, so that the water flow collides and rubs against the clothes to achieve washing and ensure the effect of washing. At the same time, a plurality of convex ribs are arranged, which extend to the peripheral wall of the washing channel. Through the cooperation between the convex ribs and the cooperation between the convex ribs and the peripheral wall of the washing channel, the water flow state is broken more fully, further ensuring the effect of washing.

[0071] Embodiment 3

[0072] like Figure 3 As shown, in order to achieve drainage of the non-porous washing bucket, a plurality of drainage ports 14 are arranged at the lowest position on the bucket bottom 5 in this embodiment, and the plurality of drainage ports 14 are distributed inside the same circular ring 13 .

[0073] The edge of the barrel bottom 5 is provided with a water guide groove 18 lower than the inner surface of the barrel bottom 5 near the barrel body 4. The water guide groove 18 is an annular groove that surrounds the barrel bottom 5. The water guide groove 18 has a gradually decreasing structure along the circumference, and the drain outlet 14 is provided at the lowest point.

[0074] If the rib 17 extends from one end away from the center of the bottom 5 of the washing tub to the peripheral wall of the washing tub body 4, washing water will remain between the other two ribs without drainage outlets after drainage, and this part of washing water can be thrown out from the dehydration outlet on the upper part of the tub body by the centrifugal force generated by the high speed during dehydration.

[0075] In this embodiment, multiple drain ports 14 are designed on the bottom 5 of the barrel, and the drain ports 14 can be designed to be very small, which has a certain function of filtering wire scraps during drainage to avoid wire scraps clogging. The multiple drain ports 14 are all distributed inside the same ring 13, mainly to facilitate sealing of the drain ports 14.

[0076] Preferably, the drain port 14 is arranged near the edge of the barrel bottom 5, and at least one drain port 14 is inscribed in the outer circumference of the outer edge of the barrel bottom 5, or the ring 13 is inscribed in the outer circumference of the outer edge of the barrel bottom 5. In this way, the drain port 14 can be ensured to be at the lowest position of the barrel bottom 5, and the water in the washing barrel 2 of the washing machine can be drained to avoid residual water.

[0077] The washing machine of this embodiment further comprises a drainage sealing device, which comprises a sealing mechanism capable of blocking and sealing the drainage port and a driving mechanism for driving the sealing mechanism to open / close the drainage port. The washing tub of the washing machine of this embodiment rotates during the washing and dehydration processes. Therefore, the position of the drainage port 14 in the washing tub is uncertain as the washing tub rotates. In order to ensure accurate sealing and opening of the drainage port, a locking hole for cooperating with the locking mechanism to lock the washing tub is provided on the outer wall of the tub bottom of this embodiment. In this way, the washing tub 2 is locked to a certain position through the cooperation of the locking mechanism and the locking hole, ensuring that the drainage port 14 is always opened at the same position.

[0078] The washing machine of the present invention includes but is not limited to the above-mentioned drainage methods. The washing tub can also be controlled to rotate at high speed, and the water in the washing tub is thrown out from the dehydration port on the upper part of the barrel body by centrifugal force. Various drainage methods are within the protection scope of the present invention.

[0079] Embodiment 4

[0080] like Figure 2 As shown, the washing machine of this embodiment adopts the mode that the driving motor 7 directly drives the washing tub 2 to rotate, and the reducer is eliminated. The output shaft of the driving motor 7 is installed on the water receiving tub 3, and can be matched with the water receiving tub 3 through a bearing.

[0081] The washing machine of the present embodiment adopts a non-porous washing barrel, which means that the washing barrel 2 does not have a through hole that allows water to flow back and forth in the water receiving barrel 3 and the washing barrel 2 during washing. The washing barrel 2 can independently hold washing water during washing. The washing machine of the present embodiment also includes a water receiving barrel 3 with an open water receiving chamber, at least the barrel bottom 5 of the washing barrel is arranged in the water receiving chamber, for collecting the washing water discharged from the washing barrel 2; the driving motor 7 is installed at the bottom of the water receiving barrel 3, and the output shaft 10 of the driving motor 7 passes through the water receiving barrel 3 and is fixedly connected to the barrel bottom 5 of the washing barrel. In order to enhance the connection strength between the output shaft 10 and the barrel bottom 5 and prevent the output shaft 10 from directly transmitting the rotational torque to the barrel bottom 5 when rotating, causing deformation of the barrel bottom, a bracket 21 is fixedly installed below the barrel bottom 5. Further, in order to prevent water leakage caused by the direct installation of the bracket 21 and the barrel bottom 5, the present invention changes the installation method of the bracket 21, cancels the fixing structure of the bracket and the barrel bottom, and designs the lower part of the barrel body 4 to extend downward and protrude from the lower surface of the barrel bottom 5. The bracket 21 is fixedly connected to the lower part of the barrel body 4 through a plurality of radially installed fixing members 22, thereby fixing the bracket 21 below the barrel bottom 5. Preferably, the fixing members 22 are screws, which are installed in a distributed manner along the circumferential direction of the barrel body and are connected to the bracket 21 through the barrel body 4 from the outside.

[0082] The main functions of the water receiving bucket 3 of this embodiment are:

[0083] 1. It is used to collect the water discharged from the washing tub 2 and discharge it, including the water discharged from the drain port and the water discharged from the dehydration port.

[0084] 2. Used for installing the bottom structural parts of the barrel such as the drive motor 7 and the drain valve.

[0085] 3. Used for hoisting the shock-absorbing suspension rod 12 to realize the installation of the washing tub 2.

[0086] Therefore, the water receiving bucket 3 of this embodiment can be selected from the outer barrel of an existing washing machine. The outer barrel used to hold water in an existing fully automatic washing machine is no longer needed or can be improved in structure. For example, a lower outer barrel can be used to save materials and relatively increase the volume of the washing barrel.

[0087] Since the speed reduction clutch is removed in the washing machine of this embodiment, the driving motor needs to bear a larger load torque, so a motor with a larger output torque is selected. As an implementation of this embodiment, the driving motor of this embodiment adopts a direct drive motor, and further adopts a direct drive variable frequency motor.

[0088] Alternatively, the driving motor can also be connected to the washing tub through a reducer, and the clutch device can be used to switch the reduction ratio of the reducer between the washing and dehydration conditions. The reducer includes an input shaft, an output shaft and a transmission gear set, the input shaft is connected to the driving motor, and the output shaft is connected to the washing tub. During washing, the clutch device connects the output shaft to the input shaft of the reducer through the transmission gear set at a differential speed, and during dehydration, the clutch device connects the output shaft to the input shaft at the same speed.

[0089] Embodiment 5

[0090] like Figure 2 As shown, the shock absorbing device of this embodiment includes a suspension shock absorbing member 11 and a supporting shock absorbing member 6, and the suspension shock absorbing member 11 and the supporting shock absorbing member 6 are both arranged between the shell 1 and the water receiving bucket 3, and are respectively connected to the shell 1 and the water receiving bucket 3, the suspension shock absorbing member 11 suspends the water receiving bucket 3 in the shell 1, and the supporting shock absorbing member 6 supports the water receiving bucket 3, and the supporting shock absorbing member 6 and the suspension shock absorbing member 11 work together to eliminate the reaction amount formed by the components of the water receiving bucket 3, reduce the shaking of the water receiving bucket 3, and avoid hitting the box.

[0091] Preferably, the suspension damping member 11 and / or the support damping member 6 are symmetrically arranged around the central axis of the water receiving bucket 3. There are 2 to 4 suspension damping members 11 and 6 respectively.

[0092] The washing machine of this embodiment is provided with a suspension damping member 11 and a support damping member 6 between the housing 1 and the water receiving tub 3, respectively. The two adopt different damping methods, and can cooperate with each other to reduce the shaking of the washing tub 2 and the water receiving tub 3, and greatly reduce the probability of the tub assembly (including the washing tub 2 and the water receiving tub 3) hitting the housing 1 during the washing process. In this way, not only the anti-deviating ability of the water receiving tub 3 and the washing tub 2 is enhanced, but also the vibration effect when passing the resonance point at low speed can be reduced, the noise of the washing machine is reduced, the safety of the washing process is enhanced, and the user experience is improved.

[0093] One end of the suspension shock absorber 11 is connected to the upper part of the shell 1, and the other end is connected to the peripheral wall of the water receiving bucket 3. One end of the supporting shock absorber 6 is hingedly connected to the lower part of the shell 1, and the other end is hingedly connected to the bottom or the peripheral wall of the water receiving bucket 3. The shell 1 includes side walls on the front, rear, left and right sides and a base at the bottom. The connection between adjacent side walls has a corner. The space between the shell and the water receiving bucket 3 corresponding to the corner is larger. Therefore, the suspension shock absorber 11 is preferably arranged in the space at the corner.

[0094] A suspension mounting seat 16 for mounting the suspension shock absorber 11 is provided on the peripheral wall of the washing machine water receiving tub 3, and the suspension mounting seat 16 protrudes outward. The suspension shock absorber 11 includes a suspension rod 12 and a shock absorber 15 for generating a damping force. The shock absorber 15 is located below the suspension mounting seat 16, and the suspension rod 12 passes through the suspension mounting seat 16 on the peripheral wall of the water receiving tub 3 and is suspended on the upper part of the housing 1. Preferably, the height of the suspension mounting seat is not lower than the horizontal height of the bottom 5 of the washing tub.

[0095] Also preferably, the extension line of the suspension shock absorber 11 intersects with the central axis of the water receiving bucket 3 .

[0096] After installation, the shock absorber 15 is stuck in the suspension mounting seat 16. When the washing machine vibrates, the suspension rod 12 and the shock absorber 15 vibrate, and the shock absorbing member in the shock absorber 15 is deformed, and the reverse force required for restoring the deformation is generated accordingly, offsetting the force of vibration, thereby reducing the vibration of the washing machine. The suspension shock absorbing member 11 can greatly reduce the vibration of the washing machine in the vertical direction, and prevent the washing machine from moving up and down relative to the ground and making loud noises.

[0097] The suspension shock-absorbing member 11 has one end of the shock absorber 15 connected to the peripheral wall of the water receiving bucket 3, so that the suspension rod 12 can be suspended and connected to the shell 1 without hindrance, and the collision between the water receiving bucket 3 and the suspension rod 12 can be avoided.

[0098] The support shock absorber 6 is arranged below the water receiving bucket 3, and its two ends are respectively hingedly connected to the bottom or peripheral wall of the housing 1 and the water receiving bucket 3, so that relative rotation can be generated. When the washing machine vibrates, the support shock absorber 6 can generate a damping force in the opposite direction to the vibration force, thereby reducing the vibration of the washing machine. Preferably, the two ends of the support shock absorber 6 are respectively connected to the housing and the water receiving bucket 3 through a universal connector.

[0099] Specifically, the supporting shock-absorbing member 6 includes a sleeve and a piston rod extending into the sleeve. The sleeve is filled with liquid or gas. One end of the piston rod extending out of the sleeve is connected to the peripheral wall or bottom wall of the water receiving bucket 3, and the bottom of the sleeve is connected to the base of the shell 1.

[0100] Alternatively, the supporting shock-absorbing member 6 is arranged in reverse, one end of the piston rod extending out of the sleeve is connected to the base of the shell 1, and the bottom of the sleeve is connected to the peripheral wall or the bottom wall of the water receiving bucket 3.

[0101] The supporting shock absorbing member 6 is preferably a shock absorbing damper, and the shock absorbing damper is a pneumatic shock absorbing damper or a hydraulic shock absorbing damper.

[0102] Embodiment 6

[0103] like Figure 4 and Figure 5As shown, in order to obtain a better supporting and shock absorbing force, so as to eliminate the reaction momentum and the vertical vibration force formed by the water receiving bucket component. The supporting and shock absorbing member 6 described in this embodiment includes two sleeves 19, wherein the sleeves 19 define a receiving cavity, one end of which has an opening and the other end is closed, the closed end of one sleeve 19 is connected to the base of the housing 1, and the closed end of the other sleeve 19 is connected to the peripheral wall or bottom wall of the water receiving bucket 3, preferably, both are movably connected by a universal connector;

[0104] The piston rod 20 is movably connected to the sleeve 19 , and its two ends are respectively extended into the two openings of the sleeve 19 in a one-to-one correspondence and are slidably disposed in the accommodating cavity of the sleeve 19 .

[0105] The accommodating chamber of the sleeve 19 is provided with a damping unit providing damping force, and the damping unit includes a damping member sleeved on the piston rod and / or a damping medium filled in the accommodating chamber of the sleeve. Specifically, the damping units provided in the two sleeves can be both damping members and damping medium, or any one of them.

[0106] Embodiment 7

[0107] like Figure 2 As shown, the suspension shock-absorbing component 11 of the present invention is arranged on the side of the water receiving bucket 3, and the supporting shock-absorbing component 6 is arranged at the bottom of the water receiving bucket 3 or below the peripheral wall. Therefore, the two shock-absorbing components are arranged up and down, that is, the washing machine adopts the upper suspension rod 12 lower damping method, which jointly plays a shock-absorbing role and has a better shock-absorbing effect.

[0108] Multiple suspension shock absorbers 11 and supporting shock absorbers 6 can be provided. Such a configuration can disperse the force and make the force on each shock absorber uniform. It can not only greatly enhance the anti-deflection ability of the water receiving bucket 3 and the washing bucket 2, but also avoid damage caused by excessive force on a single shock absorber, thereby ensuring a good shock absorption effect.

[0109] The suspension damper 11 and the support damper 6 may be located on the same plane in the vertical direction, or may not be located on the same plane. There are multiple suspension dampers 11, which are evenly distributed along the circumference of the water receiving bucket 3, and there are multiple support dampers 6, which are evenly distributed around the central axis of the water receiving bucket 3; the projection of the suspension damper 11 in the horizontal direction is spaced from the projection of the support damper 6 in the horizontal direction.

[0110] The supporting shock absorbing member 6 is tilted from bottom to top along the radial direction of the water receiving bucket 3. There are four suspension shock absorbing members 11 and four supporting shock absorbing members 6, and the suspension shock absorbing members 11 and the supporting shock absorbing members 6 form a group in a one-to-one correspondence, and each group is arranged at the corners of two adjacent side walls of the shell.

[0111] Alternatively, the two are arranged on different planes in the vertical direction, that is, the two are arranged staggered up and down. In this way, the shock absorption effect can be more uniform and stable. The suspension shock absorber 11 and the support shock absorber 6 are two, each of which is arranged at the corner of two adjacent side walls of the shell;

[0112] Preferably, the projections of the suspension shock absorbing member 11 and the support shock absorbing member 6 on the outer shell base along the outer circumference of the water receiving bucket 3 are distributed at intervals.

[0113] The suspension shock absorber 11 and the supporting shock absorber 6 are both arranged obliquely between the shell 1 and the water receiving bucket 3; in this way, the fixation is better and the margin of shock absorption is larger, which can not only reduce the vibration in the vertical direction, but also play a certain shock absorption role in other directions.

[0114] Preferably, the suspension damping member 11 is inclined from bottom to top and from inside to outside, and the support damping member 6 is inclined from bottom to top and from outside to inside (see Figure 5 ).

[0115] When the washing machine vibrates, the water receiving bucket 3 deviates outwards, and the distances between the ends of the two shock absorbing parts connected to the housing 1 and the central axis of the washing machine are greater than the distances between the ends of the shock absorbing parts connected to the water receiving bucket 3 and the central axis of the washing machine, which can generate deformation or damping force to a greater extent with the vibration of the washing machine, and the shock absorbing effect is better. Since the vibration of the upper part of the water receiving bucket 3 is greater than that of the lower part, the suspension shock absorbing part 11 is inclined from bottom to top and from inside to outside, and the distance between the upper end and the water receiving bucket 3 is large, which prevents the water receiving bucket 3 from hitting the suspension rod 12, and can also be more stably suspended on the upper part of the housing 1.

[0116] Alternatively, the support and shock absorbing member 6 is arranged to be inclined from bottom to top along the tangent direction of the water receiving bucket 3 (see Figure 4 ).

[0117] Preferably, there are four suspension dampers 11 and four support dampers 6 , and the suspension dampers 11 are arranged at the corners of two adjacent side walls of the shell. The suspension dampers 11 and the support dampers 6 are spaced apart along the periphery of the water receiving bucket 3 .

[0118] Four suspension shock absorbers 11 are arranged on the outer side of the water receiving bucket 3, and are evenly distributed around the water receiving bucket 3; four support shock absorbers 6 are arranged on the bottom or the peripheral wall of the water receiving bucket 3, and are also evenly distributed around. In this way, the planes formed by the two groups of relatively arranged support shock absorbers 6 can be perpendicular to each other, and the planes formed by the two groups of relatively arranged suspension shock absorbers 11 are also perpendicular to each other, which has a good effect of enhancing the anti-deflection ability of the bucket assembly and reducing the vibration effect when passing the resonance point at low speed.

[0119] At this time, the projection of the suspension shock absorber 11 in the horizontal direction and the projection of the support shock absorber 6 in the horizontal direction are distributed at intervals, that is, a support shock absorber 6 is arranged below two adjacent suspension shock absorbers 11, and a suspension shock absorber 11 is arranged above two adjacent support shock absorbers 6. In this way, the cooperation of each shock absorber can play a shock-absorbing role in more directions, and the effect of preventing the water receiving bucket 3 and the washing bucket 2 from shifting is better, and the probability of the water receiving bucket 3 hitting the shell 1 is further reduced.

[0122] Furthermore, during the washing process, the washing machine controls the washing tub to rotate forwardly at a first acceleration for a first set time, and after the forward rotation ends and stops for a set time, the washing tub is controlled to rotate reversely at a second acceleration for a second set time, and after the reverse rotation ends and stops for a set time, the washing tub is rotated forward again, and this cycle is repeated;

[0123] Preferably, as the load of the washing machine increases / decreases, the one-way action time and stop time of the driving motor can be adjusted accordingly, and are positively correlated with the load of the washing machine;

[0124] Preferably, the unidirectional action time of the driving motor is 0.5-5S, and the unidirectional stop time of the driving motor is 0-5S;
