Technical Field

[0001] The invention belongs to the technical field of washing equipment, and in particular relates to a hanging rod assembly for washing equipment and the washing equipment. Background Art

[0002] With the development of the national economy, washing machines have become a necessary household appliance. In order to make washing machines adapt to more application scenarios, such as washing thicker sheets, quilt covers, and curtains, more users choose higher-power washing machines, such as washing machines with a rated washing capacity of 8Kg or even more.

[0003] The washing drum of such a washing machine with a large washing capacity has a larger volume so as to hold the clothes to be washed. In order to avoid the washing machine taking up a large area and to increase the commonality of the same type of products so that the base and other structures of the washing machine can be common, generally speaking, the inner volume of the washing drum is increased by increasing the depth of the washing drum.

[0004] Therefore, for washing machines with large washing capacities, the height of the washing drum is usually greater than its diameter. During the washing and spinning process, the center of gravity is unstable, the vibration becomes greater, and a large vibration noise will be generated. In severe cases, the entire washing machine will move, and the spinning process will stop when the eccentricity is large.

[0005] In the existing washing machines, a spring is provided at the connection between the suspension rod and the washing drum to adjust the vibration and eccentricity problems occurring during the washing and drying processes. However, since the upper part of the suspension rod is fixed to the shell and the housing of the washing machine and the position is not adjustable, the vibration and eccentricity problems cannot be completely solved in the existing technology. Summary of the invention

[0006] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a hanging rod assembly for a washing device and a washing device, which can produce lateral displacement and angle adjustment through the hanging rod and the angle fixing parts, thereby further improving the shock absorption effect during the washing process.

DETAILED DESCRIPTION

[0044] 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.

[0045] 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.

[0046] 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.

[0047] The present invention first provides a suspension rod assembly for a washing device, including a suspension rod 3 and an angle fixing member 5. One end of the suspension rod 3 is assembled and connected to a housing of the washing device and / or a fixing member in the housing through the angle fixing member 5, and the other end is assembled and connected to a washing drum 2 in the washing device; the suspension rod 3 can produce lateral displacement and angle adjustment at the angle fixing member 5.

[0048] In this embodiment, a pulsator washing machine is taken as an example to introduce the specific structure of the hanging rod assembly for a washing device and the washing device provided by the present invention.

[0049] like Figures 1 to 18 As shown, the pulsator washing machine includes a shell and a washing drum 2, and also includes a suspension rod 3. There are multiple suspension rods 3, which are evenly distributed in the space surrounded by the shell. One end of the suspension rod 3 is connected to the lower part of the outer wall of the washing drum 2, and the other end is assembled and connected to the shell. The suspension rod 3 is tilted, and the angle between the center line of the suspension rod 3 and the outer wall of the washing drum is an acute angle. The washing drum 2 is hoisted in the space surrounded by the shell through the tilted suspension rod 3. Through the evenly arranged multiple suspension rods 3, it is ensured that the washing drum 2 is stably hoisted in the space surrounded by the shell.

[0050] The pulsator washing machine also includes a lifting device 4, which is assembled and connected with the suspension rod 3. By driving the suspension rod 3, the washing tub 2 is driven to rise and fall linearly, so as to shorten the distance between the bottom of the washing tub 2 and the door body.

[0051] like Figures 1 to 4As shown, the shell includes a base and a box body 1, the box body 1 is a hollow rectangular structure, including four side panels connected in sequence end to end, the connection between adjacent side panels is rounded, or the box body 1 can be an integrally formed structure, or a whole plate is continuously bent and then connected end to end, the bending part is rounded, the bottom of the box body 1 is fixed to the base, and a balance ring, a door body and other structures are arranged on the top, and the washing drum 2 is arranged in the space surrounded by the box body 1 and the base.

[0052] Preferably, there are four suspension rods 3, which are respectively assembled and connected to the four corners of the box body 1, and the lifting device 4 is arranged on at least two of the suspension rods 3, and the two suspension rods 3 are distributed inside the box body 1 along the diagonal line of the box body 1.

[0053] The base is provided with a driving mechanism for driving the washing tub 2 to rotate and driving the impeller at the bottom of the inner tub to rotate, and a counterweight is provided on the base to prevent the washing machine from shifting during the operation of the washing program.

[0054] The washing tub 2 includes an inner tub and an outer tub that are set together, and the lower part of the suspension rod 3 is assembled and connected to the outer wall of the outer tub. The top of the outer tub and the inner tub are provided with a balancing ring, and a certain gap is left between the balancing ring and the top of the washing tub 2. The top of the box body 1 is provided with a top cover, and a door body for opening and closing the inlet of the washing tub 2 is provided on the top cover, and the balancing ring is provided at the lower part of the top cover.

[0055] A plurality of protrusions are arranged on the inner wall of the inner drum to disrupt the water flow in the inner drum and enhance the washing effect; a plurality of reinforcing ribs are arranged on the outer wall of the outer drum to enhance the strength of the outer drum.

[0056] like Figures 2 to 4 As shown, at the lower part of the outer cylinder, from bottom to top, at the 1 / 6 to 1 / 4 height of the outer cylinder, a mounting seat 21 is provided, the mounting seat 21 is integrally formed with the outer cylinder wall, or fastened by screws, and the mounting seat 21 and the outer cylinder wall can be fixed by any existing or future possible technology without limitation or requirement.

[0057] The lower part of the outer drum, from the position of the mounting seat 21 downward to the bottom, the outer wall converges inward, that is, the side wall of the lower part of the outer drum is inclined from the position of the mounting seat 21 from top to bottom inward (toward the inside of the washing drum, the center point of the washing drum), and the bottom is retracted toward the direction of the central axis of the washing drum 2, so that the bottom diameter of the outer drum is smaller than the top diameter. In the process of the suspension rod 3 driving the washing drum 2 to rise, the angle between the suspension rod 3 and the box body 1 increases, the lower part deflects toward the central axis of the washing drum 2, and the lower side wall of the outer drum retracts inward, providing necessary avoidance space for the deflection of the suspension rod 3.

[0058] like Figure 3As shown, the mounting seat 21 includes a top plate 211, one side of which has the same curved surface structure as the outer wall of the outer cylinder, and is integrally formed with the outer wall of the outer cylinder or fixed to the outer wall of the outer cylinder in any other manner, and the top plate 211 is perpendicular to the outer cylinder, that is, the top surface of the top plate 211 is parallel to the top surface of the base, or the top plate 211 is perpendicular to the suspension rod 3 in a normal state (when the washing cylinder 2 is in the washing position and is not lifted). A mounting hole 212 is provided on the top plate 211, and the bottom of the suspension rod 3 is inserted into the mounting hole 212, so that the lower part of the suspension rod 3 is assembled and connected with the outer cylinder through the mounting seat 21.

[0059] A slot 214 is also provided on the top plate 211. One side of the slot 214 is opened on the outside of the top plate 211 (the direction toward the central axis of the washing tub 2 is the inside, and the direction away from the central axis of the washing tub 2 is the outside, the same below), and the other side is connected to the mounting hole 212. The width of the slot 214 is slightly smaller than the diameter of the suspension rod 3. The suspension rod 3 passes through the slot 214 and is inserted into the mounting hole 212 by interference fit. The diameter of the mounting hole 212 is larger than the diameter of the suspension rod 3. The suspension rod 3 has a certain degree of freedom in the mounting hole 212, and the axial direction of the suspension rod 3 can produce lateral displacement in the mounting hole 212. The width of the slot 214 is slightly smaller than the diameter of the suspension rod 3, which prevents the suspension rod 3 from escaping from the slot 214 without affecting the plug-in connection between the suspension rod 3 and the mounting hole 212.

[0060] A surrounding wall 213 is provided on the outer periphery of the bottom surface of the top plate 211, and the top of the surrounding wall 213 is vertically connected to the bottom surface of the top plate 211. A notch 215 is provided at the position of the surrounding wall 213 corresponding to the slot 214. The width of the notch 215 is greater than or equal to the diameter of the suspension rod 3, so that the suspension rod 3 can enter and exit along the notch 215.

[0061] The top plate 211 is a plate-like structure, and each corner is rounded. The top surface shape of the surrounding wall 213 is similar to the outer peripheral shape of the top plate 211, and the corner position after the rounding treatment relative to the top plate 211 is arc-shaped.

[0062] A plurality of reinforcing ribs are provided between the top surface of the top plate 211 and the side wall of the outer tube. Specifically, the reinforcing ribs include at least vertical reinforcing ribs and transverse reinforcing ribs 24. Figure 3As shown in the figure, the vertical stiffeners at least include two long vertical stiffeners 22 arranged in parallel. The long vertical stiffeners 22 are right-angled triangular plates. The longitudinally arranged right-angled side is the vertical side wall, which is integrally formed with the outer wall of the outer cylinder or fixed by any means. The bottom horizontal side wall is vertically fixed to the top surface of the top plate 211, and the fixing points avoid the positions of the mounting holes 212 and the card slots 214. The end of the vertical side wall is directly connected to the end of the horizontal side wall or connected into a "single person radical" shape. The long vertical stiffeners 22 are vertically fixed to the top surface of the top plate 211, and are arranged on both sides of the mounting hole 212, near both ends of the top plate 211. Preferably, the outer wall of the long vertical stiffener 22 (in the direction away from the mounting hole 212) is flush with the side wall of the top plate 211; or preferably, the inner wall of the long vertical stiffener 22 is fixed to or integrally formed with the side wall of the top plate 211.

[0063] Inside the two long vertical stiffeners 22 arranged in parallel, on both sides of the mounting hole 212, a short vertical stiffener 23 is respectively arranged, and the two short vertical stiffeners 23 are arranged in parallel with each other. The short vertical stiffener 23 is also in the shape of a right-angled triangular plate structure, and the two right-angled sides are integrally formed with the top surface of the top plate 211 and the side wall of the outer cylinder or fixed to each other by any conventional or future possible technologies. The difference between the short vertical stiffener 23 and the long vertical stiffener 23 is that the angles of the two acute angles are different.

[0064] The two long vertical stiffeners 22 and the short vertical stiffeners 23 are parallel to each other.

[0065] Multiple mutually parallel horizontal stiffeners 24 are arranged in the space enclosed by the two long vertical stiffeners 22 described above and above the short vertical stiffeners 23. The multiple horizontal stiffeners 24 have similar structures and are plate structures, and the bottom surface is a curved surface structure, which is integrally formed with the outer wall of the outer cylinder or fixed to each other by any conventional or future possible technologies. The side wall of the horizontal stiffener 24 has a curved surface with the opposite arc direction to the outer wall of the outer cylinder. Further, from top to bottom, the width between the lowest point of the side wall of the horizontal stiffener 24 and the outer wall of the outer cylinder gradually increases.

[0066] Outside the long vertical stiffener 22, multiple side stiffeners 25 parallel to the horizontal stiffeners 24 are arranged.

[0067] Such as Figures 2 to 8 、 Figures 14 to 18As shown, the lifting device 4 is assembled and connected with the upper part of the rod body 32. In this embodiment, the lifting device 4 includes a screw rod 44, a bearing 43 and a driving device. The screw rod 44 is integrally formed with the rod body 32, that is, the screw rod 44 is integrated with the suspension rod 3 and is a part of the upper part of the suspension rod 3. An internal thread is arranged on the inner wall of the center hole of the bearing 43, which is threadedly connected with the screw rod 44. The bearing 43 is connected with the output shaft of the driving device. Driven by the driving device, the bearing 43 rotates, driving the screw rod 44 to rise and fall linearly along the bearing 43, thereby driving the suspension rod 3 to rise and fall linearly along the bearing 43, thereby realizing the vertical lifting of the washing drum.

[0068] Further, such as Figures 14 to 18 As shown, the bearing 43 and the output shaft of the driving device are connected to each other by means of tooth meshing. The upper part of the bearing 43 has a smooth surface, and the lower part has external teeth. The output shaft of the driving device is connected to the bearing gear 42, and the bearing gear 42 meshes with the teeth of the lower part of the bearing 43. The output shaft of the driving motor 41 drives the bearing gear 42 to rotate. The bearing gear 42 can drive the bearing 43 to rotate synchronously by meshing. The screw rod 44 is lifted and lowered linearly along the internal thread of the bearing 43. During the lifting process, the screw rod 44 is lifted and lowered linearly along the central axis of the bearing 43 without rotating.

[0069] The driving device is a motor 41, one end of the fixing seat is assembled and connected with the suspension rod 3, and the other end fixes the motor 41, and the motor 41 is assembled with the suspension rod 3. In this embodiment, the lifting device 4 is assembled and connected with the suspension rod 3, on the one hand, to prevent the motor 41 from being fixed to the box body 1 and causing the box body 1 to vibrate; on the other hand, if the lifting device is fixed to the box body 1 or other components, the suspension rod 3 will produce lateral displacement during the linear lifting process. During the rising process, the meshing pressure between the bearing 43 and the bearing gear 42 is too large, which may cause the teeth to collapse, and during the descending process, the bearing 43 and the bearing gear 42 may be separated. The lifting device 4 is assembled and connected with the suspension rod 3, which can solve this problem. While driving the suspension rod 3 to rise and fall linearly, it will not be affected by the lateral displacement of the suspension rod 3.

[0070] Further, such as Figure 8 , Fig.17 As shown, the fixing seat includes a motor mounting seat 46 and a bearing mounting seat 45 which are assembled and fixed to each other. The motor mounting seat 46 is an inverted L-shaped structure. The top plate of the motor mounting seat 46 is fixed to the outer casing of the motor 41 with bolts, and the outer side of the side plate is fixedly connected to the bearing mounting seat 45 through a connecting piece 47 or directly. If necessary, the outer casing of the motor 41 is fixed to the side plate and top plate of the motor mounting seat 46 respectively.

[0071] In this embodiment, the bearing mounting seat 45 includes a fixing seat base 451, and the fixing seat base 451 is assembled and connected with the bearing 43, so that the fixing seat is connected and fixed to the suspension rod 3 through the bearing 43. Fig. 9 and Fig.15, 16 As shown, the fixed seat base 451 has a hollow portion assembled with the bearing 43, and the upper portion of the bearing 43 is inserted into the hollow portion of the fixed seat base 451 and can rotate freely in the hollow portion. In order to prevent the relative rotation between the bearing 43 and the fixed seat base 451 from wearing the inner wall of the fixed seat base 451, a bearing plug-in 431 is provided between the bearing 43 and the fixed seat base 451.

[0072] In this embodiment, the cross-section of the bearing 43 is an inverted T-shape, the vertical arm is the small diameter end, the horizontal arm is the large diameter end, the small diameter end is fitted and connected with the bearing plug-in 431, and the bearing plug-in 431 is inserted into the hollow part of the fixed seat base 451, so that the small diameter end of the bearing 43, the bearing plug-in 431, and the fixed seat base 451 are fitted and connected in sequence.

[0073] A press-type structure is correspondingly arranged between the bearing plug-in 431 and the fixed seat base 451. For example, a plurality of longitudinal arc-shaped depressions are symmetrically arranged on the outer wall of the bearing plug-in 431, and an arc-shaped protrusion is correspondingly arranged on the inner wall of the fixed seat base 451. Through the matching arc-shaped depressions and arc-shaped protrusions, it is limited that the fixed seat base 451 and the bearing plug-in 431 cannot rotate.

[0074] The bearing 43 is inserted into the axial hole of the bearing plug-in 431, and the bearing 43 and the bearing plug-in 431 are smoothly connected. If necessary, lubricating oil is applied between the contact surfaces. When the bearing 43 rotates, it will not drive the bearing member 431 and the fixed seat base 451 to rotate.

[0075] The outer periphery of the large diameter end of the bearing 43 is provided with external teeth (not shown in the figure), which mesh with the bearing gear 42, and the top surface is against the bottom surface of the bearing plug-in 431 and the bottom surface of the fixed seat base 451.

[0076] like Fig.17 As shown, the inner wall of the fixed seat base 451 is generally in a "ㄣ" shape, and the top longitudinal side wall, the middle transverse wall, and the bottom longitudinal side wall are vertically connected in sequence. The bearing plug-in 431 is located in the space surrounded by the bottom longitudinal side wall, the middle transverse wall, the outer wall of the small diameter end of the bearing 43, and the large diameter top surface. Preferably, the top longitudinal side wall of the fixed seat base 451 is flush with the inner wall of the bearing plug-in 431.

[0077] The top surface of the fixing seat base 451 is integrally connected with a fixing seat cylinder wall 453 . The outer diameter of the fixing seat cylinder wall 453 is smaller than the outer diameter of the fixing seat base 451 , thereby providing necessary installation space for the motor mounting seat 46 .

[0078] The lower portion of the suspension rod seat 36 is inserted into the central hole of the fixing seat tube wall 453 . Specifically, the cylindrical structure 361 at the lower portion of the suspension rod seat 36 is inserted into the central hole of the fixing seat tube wall 453 .

[0079] The inner diameter of the fixed seat cylinder wall 453 is larger than the inner diameter of the longitudinal side wall at the top of the fixed seat base 451, so that a step is formed between the bottom of the inner wall of the fixed seat cylinder wall 453 and the top of the fixed seat base 451. The bottom of the cylindrical structure 361 is partially or completely seated on this step, so that there is enough gap between the bottom of the cylindrical structure 361 and the top surface of the bearing 43, and there is no direct contact, thereby preventing the cylindrical structure 361 from rotating and wearing under the drive of the bearing 43.

[0080] The bottom of the fixed seat wall 453 can be directly seated on the top surface of the fixed seat base 451, or Fig.17 As shown, the bottom of the fixing seat tube wall 453 is connected to the top surface of the fixing seat base 451 through a connecting wall, and the outer diameter of the connecting wall is smaller than the outer diameters of the fixing seat tube wall 453 and the fixing seat base 451 .

[0081] After the motor mounting seat 46 is fixed to the bearing mounting seat, the inner side of the side plate of the motor mounting seat 46 (the side facing the motor 41 ) is flush with the outer side of the fixing seat base 451 .

[0082] There are two fixed seat side support plates 452, which are symmetrically arranged on the outside of the fixed seat cylinder wall 453, and the bottom is seated on the top surface of the fixed seat base 451, or there is a certain gap between the top surface of the fixed seat base 451. The fixed seat side support plates 452 are integrally formed with the fixed seat base 451 and / or the fixed seat cylinder wall 453, or are fixed to the fixed seat cylinder wall 453 into an integral structure by means of clamping, bonding, or screw fixing. In this embodiment, a protrusion is arranged on the outer periphery of the fixed seat cylinder wall 453, and the fixed seat side support plates 452 are clamped and fixed on the fixed seat cylinder wall 453 by means of interference fit with the protrusion.

[0083] The top of the fixed seat side support plate 452 is provided with a buckle facing the cylindrical structure 361 (towards the center point of the fixed seat cylinder wall 453), and the top of the fixed seat side support plate 452 is higher than the fixed seat cylinder wall 453. After the assembly is completed, the lower part of the second recessed portion 53 is located in the space surrounded by the relatively arranged buckles, and the relative position of the bearing mounting seat 45 on the suspension rod 3 relative to the angle fixing member 5 is limited by the buckle.

[0084] The fixing seat side support plate 452 is connected and fixed to the motor mounting seat 46 through a connecting piece 47 .

[0085] A positioning profile (not shown) is also provided inside the fixed seat cylinder wall 453, and a matching structure is correspondingly provided on the screw rod 44. The positioning profile ensures that the suspension rod 3 can only move linearly in the bearing mounting seat 45 but cannot rotate.

[0086] The supporting structure matching the positioning profile can be arranged on the screw rod 44, or on the rod body 32 at the upper end of the screw rod 44. In this embodiment, the upper end of the screw rod 44 is provided with a profiled rod body 31, such as a hexagonal prism at the upper end of the screw rod 44, or other regular polygons in cross section. The starting position of the profiled rod body 31 is located above the top surface of the bearing 43. Preferably, the diameter of the profiled rod body 31 is larger than the outer diameter of the screw rod 44, so that a limiting step is formed between the profiled rod body 31 and the top of the screw rod 44, and the limiting step is against the top surface of the bearing 43, limiting the maximum distance of the descent of the suspension rod 3, and preventing the suspension rod 3 from driving the washing tub 2 to drop excessively, thereby damaging the washing tub 2 and / or other components at the bottom of the washing tub 2.

[0087] A pressure sensor is arranged between the limit step formed at the connection between the screw rod 44 and the profiled rod body 31 and the top surface of the bearing 43. When the suspension rod 3 descends and the limit step conflicts with the top surface of the bearing 43, the pressure sensor is triggered. The pressure sensor sends a control signal to the controller of the washing machine or directly to the motor 41, and the controller or directly controls the motor 41 to stop moving.

[0088] like Figures 4 to 8 , 14, 17 A hanger seat 36 is mounted on the profiled rod body 31, and the hanger seat 36 includes an integrally formed cylindrical structure 361 and a hanger upper support 362. The cylindrical structure 361 is inserted into the bearing mounting seat 45 from top to bottom, and the profiled rod body 31 is inserted into the cylindrical structure 361. Preferably, a gap is left between the lower end surface of the hanger seat 36 and the top surface of the bearing 43 inserted into the bearing mounting seat 45 to prevent the hanger seat 36 from rotating under the drive of the bearing 43 when it directly contacts the top surface of the bearing 43, thereby driving the hanger 3 to rotate.

[0089] Preferably, a positioning profile is provided on the inner wall of the cylindrical structure 361 to prevent the suspension rod 3 from rotating relative to the cylindrical structure 361 .

[0090] In the gap between the suspension rod seat 36 and the top surface of the bearing 43, the inner wall of the bearing mounting seat 45 contacts the profiled rod body 31, and a matching structure is provided on the bearing mounting seat 45 to limit the profiled rod body 31 from rotating in the bearing mounting seat 45; the outer diameter of the cylindrical structure 361 is smaller than the diameter of the upper part of the bearing 43 inserted into the bearing mounting seat 45, such as Fig.17As shown, the outer diameter of the cylindrical structure 361 is smaller than the outer diameter of the bearing plug-in 431, so that the cross-section of the inner wall of the bearing mounting seat 45 is in the shape of a "J", which can also be called a hat-shaped structure. The inner wall of the bearing mounting seat 45 is also provided with a matching structure of a positioning press as described above. On the one hand, it limits the screw rod 44 or the rod body from rotating in the bearing mounting seat 45. On the other hand, as described above, a gap is left between the bottom of the cylindrical structure 361 and the bearing 43, and the more protruding part of the middle part of the "J"-shaped or hat-shaped structure is located at the gap, so as to avoid excessive installation of the hanger seat 36 and causing the cylindrical structure 361 to directly contact the bearing 43, thereby driving the hanger seat 36 to rotate. Finally, the motor 41 is integrated with the hanger 3 through the fixed seat, instead of fixing the motor 41 to the outer casing, causing the outer casing to vibrate.

[0091] The profiled rod body 31 is inserted into the cylindrical structure 361, and the inner wall of the cylindrical structure 361 is provided with a matching structure matching the profiled rod body 31, further limiting the profiled rod body 31, the bi rod, and the rod body 32 to only be able to rise and fall linearly but not to rotate.

[0092] A suspension rod support 362 is provided at the upper part of the cylindrical structure 361. The bottom of the side wall of the suspension rod support 362 is fixed to the upper part (not the top) of the cylindrical structure 361, the top is open, and the side wall is a curved structure. Preferably, the outer wall of the suspension rod support 362 is a spherical structure or a spherical-like structure, which is embedded in the second recessed portion 53 of the corner fixing member 5. The outer wall of the suspension rod support 362 matches the inner wall of the lower hemispherical side wall of the corner fixing member 5, so that the suspension rod support 362 can rotate in the second recessed portion 53 of the corner fixing member 5.

[0093] The upper part of the cylindrical structure 361 is inserted into the suspension rod support 362, and the top of the cylindrical structure 361 is flush with the top of the suspension rod support 362, or the top of the cylindrical structure 361 is slightly lower than the top of the suspension rod support 362, and reinforcing ribs are arranged between the outer wall of the cylindrical structure 361 and the inner wall of the suspension rod support 362 to improve the strength of the suspension rod support 362 and prevent the suspension rod support 362 from breaking when the angle of the cylindrical structure 361 is steplessly adjusted.

[0094] The suspension rod support 362 is embedded in the lower hemispherical arc-shaped side wall 531 of the second recessed portion 53, the cylindrical structure 361 is inserted into the limiting column 532, and the outer diameter of the cylindrical structure 361 is smaller than the inner diameter of the limiting column 532. Under normal circumstances, the cylindrical structure 361, the limiting column 532, the suspension rod support 362 and the arc-shaped side wall 531 of the second recessed portion 53 are concentrically arranged, and the cylindrical structure 361 can be in the limiting column 532, that is, the suspension rod support 362 can produce lateral displacement in the second recessed portion 53 and adjust the angle between the suspension rod 3 and the box body 1.

[0095] When the bearing 43 drives the screw rod 44 to rise and fall, the profiled rod body 31 rises and falls along the cylindrical structure 361. When rising, the top of the profiled rod body 31 extends out from the top of the cylindrical structure 361. At the same time, the profiled rod body 31 produces a lateral displacement in the limiting column 532, and the rod body 32 produces a lateral displacement at the mounting hole 212. The angle between the suspension rod 3 and the box body 1 changes. The spherical matching structure between the suspension rod 3 and the corner fixing piece 5 and between the suspension rod 3 and the mounting seat 21 realizes stepless adjustment of the angle between the suspension rod 3 and the box body 1.

[0096] It should be noted that the lifting device 4 drives the washing drum 2 through the suspension rod 3 during the lifting process, and the lifting distance is limited. Therefore, the lateral displacement and angle change of the suspension rod 3 at the connection point with the housing 1 and the washing drum 2 are relatively small. Therefore, the size change of the angle fixing member 5, the mounting seat 21 and the suspension rod 3 structure provided by the present invention is not very large compared with the conventional structure, and will not affect the structural size of the conventional washing machine housing 1, especially the installation position and specific assembly connection of other components in the housing 1. And according to the specific data of the lateral displacement and angle change of the suspension rod 3 at the angle fixing member 5 and the mounting seat 21 when the washing drum 2 rises to the highest position, the inner diameter of the limit column 532, the outer diameter of the profiled rod body 31, the inner diameter of the mounting hole 212, and the outer diameter of the vertical arm of the rod body 32 / suspension rod support 34 can be determined.

[0097] When the structure provided by the present invention is applied to a pulsator washing machine, the bearing 43, the fixing seat, the motor 41, the bearing gear 42 and the suspension rod 3 are assembled in sequence according to the characteristics and sequence of the assembly structure. Specifically:

[0098] Assemble the bearing 43 and the bearing mounting seat 45 into place, and the bottom surface of the bearing mounting seat 45 abuts against the top surface of the pressed step, which means the assembly is in place;

[0099] Adjust the insertion angle of the suspension rod 3 so that the upper profiled rod body 31 and the matching structure inside the bearing mounting seat 45 are aligned. After the rod body 32 passes through the first recessed portion 52 and the second recessed portion 53 of the angle fixing member 5 from top to bottom, the rod body 32 coming out of the limiting column 532 passes through the bearing mounting seat 45 and the bearing 43 in sequence. The profiled rod body 31 is engaged with the matching structure inside the bearing mounting seat 45 until the screw rod 44 contacts the top thread of the bearing 43.

[0100] Rotate the bearing 43 to make the push rod rise and fall along the bearing 43 in a straight line until the last thread of the screw rod 44 is flush with the bottom surface of the bearing 43, then stop rotating the bearing 43, and assemble the suspension rod 3, the bearing 43 and the fixing seat into place;

[0101] The cylindrical structure 361 of the suspension rod seat 36 passes through the first recessed portion 52 and the second recessed portion 53 from top to bottom, and then passes through the limiting column 532. The position of the suspension rod seat 36 is adjusted, and the suspension rod seat 36 is assembled with the profiled rod body 31. The suspension rod seat 36 is pushed with force. When the suspension rod seat 36 cannot continue to move downward, the suspension rod seat 36 is assembled with the bearing mounting seat 45. The angle fixing member 5 is integrated and assembled with the suspension rod 3 through the suspension rod seat 36.

[0102] The rod body 32 and the lifting device 4 are assembled in place. When the rod body 32 and the lifting device 4 are assembled, the profiled rod body 31 may have been inserted into the limiting column 532 of the corner fixing piece 5, or after the rod body 32 and the lifting device 4 are assembled, the profiled rod body 31 may be inserted from bottom to top from the limiting column 532 into the first recessed portion 52 and the second recessed portion of the corner fixing piece 5, and then the suspension rod seat 36 may be assembled to assemble and connect the suspension rod 3 and the corner fixing piece 5; the rod body 32 may be first inserted into the first recessed portion 52 and the second recessed portion 53, and then the bearing 43 and the bearing mounting seat 45 components and the suspension rod seat 36 may be sequentially assembled, or the rod body 32 may be first inserted into the first recessed portion 52 and the second recessed portion 53, and then the profiled rod body 31 and the suspension rod seat 36 may be assembled and connected, and then the bearing 43, the bearing mounting seat 45 and the suspension rod 3 and the screw rod 44 below the limiting column 532 may be assembled and connected. There is no requirement or restriction on the assembly order of the suspension rod seat 36, the bearing 43, the bearing mounting seat 45 and the suspension rod 3, as long as no assembly interference occurs;

[0103] After the profiled rod body 31 at the upper part of the suspension rod 3 is assembled and connected with the angle fixing piece 5, for the convenience of assembly, in this embodiment, after the waterproof cap 33, buffer pad 38, suspension rod support 34, spring seat 39, spring, suspension rod base 37 and rod body 32 are sequentially inserted into place, the rod body 32 between the waterproof cap 33 and the buffer pad 38 is aligned with the groove 214 of the top plate 211 of the mounting seat 21, the rod body 32 at the lower end of the waterproof cap 33 or the vertical arm of the suspension rod support 34 mounted on the rod body 32 is aligned with the notch 215 on the surrounding wall 213 of the mounting seat 21, the suspension rod 3 is pushed hard, so that the rod body 32 is inserted into the mounting hole 212 from the groove 214 by interference fit, and the buffer pad 38, the suspension rod support 34 and the spring seat 39 enter the space enclosed by the surrounding wall 213 and the outer drum, thereby assembling the suspension rod 3 with the washing drum 2 and the angle fixing piece 5.

[0104] The two right-angled sides of the corner fixing member 5 are overlapped and plugged with the top of the box body 1 respectively, so that the suspension rod 3 is assembled and connected with the box body 1 and the washing drum 2. By adjusting the position of the bearing 43 and the screw rod 44, the length of the suspension rod 3 between the mounting seat 21 and the corner fixing member 5 is adjusted.

[0105] As described above, the present embodiment provides an assembly method and sequence of the suspension rod 3 itself, and the connection method and sequence of the suspension rod 3, the corner fixing member 5, and the washing drum 2. In actual application, the assembly sequence can be adjusted arbitrarily according to the process arrangement at the assembly site, and is not limited to the assembly sequence described above, nor can it be regarded as a limitation of the present invention due to the above.

[0106] Each of the four corners of the box body 1 is provided with an angle fixture 5, and the top cover presses the angle fixture 5 onto the top of the box body 1, and the angle fixture 5 is further fixed to the top cover via the lifting lug 513. A suspension rod 3 as described above is provided at each angle fixture 5 of the top cover, and the lower part of each suspension rod 3 is connected to the washing tub 2 via the mounting seat 21, so that the washing tub 2 is suspended in the space surrounded by the outer shell. And a lifting device 4 is provided on at least two suspension rods 3 arranged diagonally.

[0107] A shock absorbing spring 6 is provided at the lower end of the rod body 32. During the washing process, especially during the spin drying process, the washing tub 2 will vibrate. In severe cases, the washing tub 2 will be seriously eccentric. The shock absorbing spring 6 can reduce the vibration of the washing tub 2 and the eccentricity.

[0108] When the top cover and the balance ring are relatively thick, and the distance between the bottom of the washing drum 2 and the door body is relatively large, the user cannot take the clothes at the bottom of the washing drum 2, or it is difficult to take them. At this time, the motor 41 can be controlled to drive the bearing 43 to rotate. The bearing 43 rotates along the thread of the screw rod 44, driving the screw rod 44 to rise and fall linearly along the bearing 43. The rising or falling action of the screw rod 44 can be controlled by controlling the rotation direction of the motor 41.

[0109] When the screw rod 44 drives the rod body 32 to rise, the height distance between the mounting seat 21 and the angle fixing piece 5 becomes smaller and smaller, but the lateral distance remains unchanged, and the positions of the mounting seat 21 and the angle fixing piece 5 remain unchanged. Therefore, during the rising process, the angle between the suspension rod 3 and the box body 1 will change. At the same time, since the diameter of the limiting column 532 is larger than the diameter of the tubular structure 361 of the suspension rod seat 36, the suspension rod seat 36 can produce a certain relative displacement in the limiting column 532; at the same time, at the lower part of the rod body 32, the diameter of the mounting hole 212 on the mounting seat 21 is larger than the diameter of the rod body 32 and the vertical arm of the suspension rod support 34 at the mounting hole 212. The rod body 32 can also produce a certain relative displacement at the mounting hole 212, so that the washing drum 2 can move up along the axial direction.

[0110] Furthermore, during the rising process of the washing drum 2, the angle a between the rod body 32 and the box body 1 will become smaller, that is, the angles between the rod body 32 and the washing drum 2 (the axis of the mounting hole 212), and between the profiled rod body 31 and the axis of the limiting column 532 of the corner fixing piece 5 will change. Therefore, in the present embodiment, the top surface of the suspension rod support 34 is an arc surface structure, that is, the fitting surface between the suspension rod support 34 and the mounting seat 21 is spherical or quasi-spherical, and the connection fitting surface between the suspension rod upper support 362 and the corner fixing piece 5 is spherical or quasi-spherical, so that the suspension rod 3 can produce lateral displacement along the bottom surface of the top plate 211 of the mounting seat 21 or along the bottom surface of the buffer pad 38, and the suspension rod 3 (cylindrical structure 361) along the limiting column 532, while also realizing the adjustment of the angle between the suspension rod 3 and the box body 1, without causing rotational limit.

[0111] Similarly, during the descending process of the washing tub 2 , a lateral displacement is generated in the opposite direction, and a rotation is generated in the opposite direction to adjust the angle between the suspension rod 3 and the housing 1 .

[0112] During the rising process, the profiled rod body 31 rises along the cylindrical structure 361, rises from the cylindrical structure 361 to the second recessed portion 53 and then enters the first recessed portion 52 (if necessary), and the top of the upper arc-shaped side wall 531 of the second recessed portion 53 is expanded outward to provide necessary avoidance space for the lateral displacement of the suspension rod 3. The first recessed portion 52 is provided to strengthen the overall strength of the angle fixing member 5 while providing necessary space for the movement and lifting of the suspension rod 3.

[0113] A detection element for detecting the position of the washing tub 2 is provided on the base or the housing 1. In practical applications, the detection element is provided at any position in the housing. By marking or providing a detection position on the washing tub 2, the position of the washing tub 2 can be detected.

[0114] The corners of the box body 1 are rounded, and a corner fixing piece 5 is installed at each of the four corners on the top of the box body 1. Figures 1 to 4 As shown in FIGS. 17 and 18 , the corner fixing member 5 includes a right-angled triangular top plate 51 arranged at the top surface, and the connection between the two right-angled sides and the connection between the right-angled side and the hypotenuse are rounded. The rounding diameter of the connection between the two right-angled sides is the same as the rounding diameter of the corner of the box body 1.

[0115] A first recessed portion 52 is provided at the center of the right-angled triangle top plate 51. The shape of the first recessed portion 52 is substantially the same as that of the right-angled triangle top plate 51 and they are arranged in the same direction, that is, the right-angled end of the first recessed portion 52 is in the same direction as the right-angled end of the right-angled triangle top plate 51 and the right-angled sides of the two components are parallel.

[0116] The first recessed portion 52 includes a side wall and a bottom wall, the top of the side wall is integrally formed with the right-angled triangle top plate 51, the main structure of the right-angled triangle top plate 51 is bent downward at the first recessed portion 52, and the bottom is integrally formed with the bottom wall, and both ends of the side wall are respectively perpendicular to the right-angled triangle top plate 51 and the bottom wall, and the connection is rounded so that the main structure of the right-angled triangle top plate 51 and the bottom wall and side wall of the first recessed portion 52 form a "Z" shape structure. Preferably, the top of the side wall is inclined toward the direction of the box body 1 to provide an escape space for the lifting rod 3 after it is raised.

[0117] At the center of the first recessed portion 52, a second recessed portion 53 is further provided, and the second recess includes an arcuate side wall 531, the top of the arcuate side wall 531 is integrally formed with the bottom wall of the first recessed portion 52, and the connection is rounded, that is, the bottom wall of the first recessed portion 52 is bent downward at the second recessed portion 53 to form the arcuate side wall 531. The arcuate side wall 531 is a smooth side wall with multiple sections of arc surfaces of different curvatures smoothly connected to form a spherical or quasi-spherical side wall, and further, it is generally in a bowl-shaped structure, and the top is expanded outward, so that the same can be provided for the lifting rod 3 to avoid space after it is raised.

[0118] Further, the arcuate sidewall 531 includes a lower spherical or spherical sidewall. Preferably, the lower part of the arcuate sidewall 531 is a spherical sidewall, and is a hemispherical sidewall. The upper part of the hemispherical sidewall is connected to the upper arcuate sidewall 531. The upper arcuate sidewall 531 includes multiple sections of arcuate surfaces with different curvatures, and the curvature of the arcuate surface decreases from top to bottom, that is, the diameter of the hollow structure surrounded by the upper arcuate sidewall 531 decreases from top to bottom and decreases in a non-uniform proportion. The upper arcuate sidewall 531 is smoothly connected to the hemispherical sidewall. In practical applications, the arcuate sidewall 531 includes multiple sections of smoothly connected arcuate surfaces to form a bowl-shaped structure.

[0119] Preferably, the upper portion of the arc-shaped side wall 531 is expanded outward to provide necessary avoidance space for adjusting the angle between the suspension rod 3 and the box body 1 .

[0120] The second recessed portion 53 further includes a limiting column 532, which is fixed at the bottom of the hemispherical side wall, and the limiting column 532 is concentrically connected to the hemispherical side wall. The limiting column 532 is a hollow structure, and the hollow part of the limiting column 532 communicates with the space surrounded by the hemispherical side wall.

[0121] It should be noted that the corner fixing member 5 is provided at the top of the box body 1 according to conventional technology. The present invention only makes creative changes to the structure of the conventional corner fixing member 5, but the setting position and function of the corner fixing member 5 remain unchanged, and the corner fixing member 5 is still assembled and connected to the top corner of the box body 1 and connected to the upper assembly of the suspension rod 3. The main structure of the right-angled triangle top plate 51 is overlapped and connected to the top of the box body 1, and is fixed by the top cover.

[0122] The acute angles of the right-angled triangle top plate 51 are trimmed, and the hypotenuse side has a downward bending portion 511. A slot 512 is formed between the bending portion 511 and the side wall of the first recessed portion 52. A limiting or fixing structure is provided on the balancing ring or other components in the outer shell, which is inserted into the slot 512, so that the right-angled triangle top plate 51 is stably fixed at the corner of the top of the box.

[0123] On one side of the right-angled triangle top plate 51, there is a lifting ear 513 with a through hole. The lifting ear 513 is fixed to the mounting assembly inside the top cover by screws, or a protrusion is provided inside the top cover and the protrusion is inserted into the through hole of the lifting ear 513, so that the corner fixing member 5 is assembled and fixed to the top cover.

[0124] Furthermore, the bottom wall of the first recessed portion 52 is inclined, and the bottom wall on the side provided with the hanging ear 513 is higher than the bottom wall on the side overlapped with the box body 1. A slot is provided at the bottom of the hemispherical side wall, and the limiting column 532 is integrally formed with the hemispherical side wall at the slot. The limiting column 532 is a hollow cylindrical structure, and the cutout of the bottom wall of the limiting wall is parallel to the bottom wall of the first recessed portion 52.

[0125] Since the bottom of the first recessed portion 52 is tilted, an angle a is formed between the central axis of the limiting column 532 and the side wall of the box body 1 (the side wall of the box body 1 on the side overlapping the right-angled triangle top plate 51), and the angle a is an acute angle. Further, the angle formed between the central axis of the limiting column 532 and the side wall of the box body 1 is the same as the installation angle of the suspension rod 3 in the normal state, that is, the angle between the central axis of the suspension rod 3 and the side wall of the box body 1 when the washing tub 2 is not lifted.

[0126] The upper part of the hanger 3 is inserted into the hollow part of the limiting column 532. The inner diameter of the limiting column 532 is larger than the diameter of the hanger 3, so that the upper part of the hanger 3 can adjust its position in the hollow part of the limiting column 532 and produce lateral displacement and adjust the angle between the central axis of the hanger 3 and the box body 1, and the adjustment angle is limited by the wall of the limiting column 532.

[0127] In this embodiment, if Figures 10 to 12 As shown, the suspension rod 3 includes a rod body 32, a suspension rod base 37 is installed at the lower part of the rod body 32, and the cross section of the suspension rod base 37 is generally an inverted T-shaped structure, and the vertical arm has a central hole, and the bottom of the rod body 32 is inserted into the central hole, or is threadedly connected to the central hole. The vertical arm can be a tubular structure with a central hole, or a truncated cone structure with a central hole.

[0128] Furthermore, the bottom of the rod body 32 has a transverse disc 321 with a diameter larger than the diameter of the central hole, and the bottom of the suspension rod base 37 is provided with a third recessed portion 371 , and the transverse disc 321 is embedded in the third recessed portion 371 .

[0129] like Figures 5 to 8As shown in Figures 1 and 13, a spring seat 39 is provided at a distance above the suspension rod base 37. The spring seat 39 is connected to the suspension rod 3 in a sleeve-type manner. The spring seat 39 and the suspension rod base 37 have similar structures, and the vertical arm of the spring seat 39 is arranged opposite to the vertical arm of the suspension rod base 37. The difference is that a disc having a diameter greater than that of the horizontal arm is provided on the top surface of the horizontal arm of the spring seat 39, and a step-like structure is formed between the top surface of the disc and the horizontal arm.

[0130] A shock absorbing spring 6 is mounted between the spring seat 39 and the suspension rod base 37. The shock absorbing spring 6 can reduce the vibration of the washing tub during operation and prevent the washing tub from having a large deviation. At the same time, it can also reduce the vibration of the lifting device during the lifting of the washing tub.

[0131] like Fig.13 As shown, the top of the disk of the spring seat 39 is assembled with a suspension rod support 34 assembled and connected with the mounting seat 21. The cross section of the suspension rod support 34 is generally T-shaped. The rod body 32 and the suspension rod support 34 are fixed together, and the suspension rod support 34 is mounted outside the rod body 32. In this embodiment, the vertical arm of the suspension rod support 34 is a truncated cone structure with a central hole, and the outer diameter of the top is smaller than the outer diameter of the bottom. The vertical arm is inserted into the mounting hole 212 of the mounting seat 21, and the maximum diameter (outer diameter) of the vertical arm is still smaller than the diameter (inner diameter) of the mounting hole 212. In practical applications, the vertical arm of the suspension rod support 34 can also be a cylindrical structure, and the diameter (inner diameter) of the mounting hole 212 is larger than the diameter (outer diameter) of the cylindrical structure. That is, the diameter (outer diameter) of the vertical wall of the suspension rod support 34 is smaller than the diameter (inner diameter) of the mounting hole 212, so that the suspension rod support 34 can produce lateral displacement in the mounting hole 212, and can adjust the angle between the central axis of the suspension rod 3 and the box body 1. The inner diameter of the vertical arm is less than or equal to the outer diameter of the rod body 32. The suspension rod support 34 and the rod body 32 are connected by interference fit to avoid relative sliding between the rod body 32 and the inner wall of the center hole of the suspension rod support 34. If necessary, the rod body 32 and the suspension rod support 34 are assembled by interference fit, and glue is applied on the inner wall of the center hole to further bond and fix the rod body 32 and the suspension rod support 34.

[0132] Furthermore, the width of the notch 215 on the surrounding wall 213 is greater than or equal to the minimum diameter of the vertical arm of the boom support 34 , the diameter of the rod body 32 is ≤ the width of the slot 214 ≤ the width of the notch 215 ≤ the maximum diameter of the vertical arm of the boom support 34 , and the width of the notch 215 is greater than the width of the slot 214 .

[0133] The bottom surface of the transverse arm of the suspension rod support 34 has a fourth recessed portion 341, and the disc of the spring seat 39 is embedded in the fourth recessed portion 341. A limiting protrusion 342 is provided on the upper part of the side wall of the fourth recessed portion 341 to prevent the disc of the spring seat 39 from escaping from the fourth recessed portion 341.

[0134] The top surface of the transverse arm of the boom support 34 is an arc-shaped surface convex upward, such as a spherical surface or a quasi-spherical surface. Preferably, the bottom surface of the top plate 211 of the mounting seat 21 is an arc-shaped concave surface matching the top surface of the transverse arm of the boom support 34. The top surface of the transverse arm of the boom support 34 is set as an arc-shaped surface, so that the boom support 34 and the top plate 211 can achieve line-surface contact instead of conventional surface-surface contact, which is convenient for adjusting the angle between the rod body 32 and the box body 1 / external cylinder.

[0135] Preferably, the suspension rod support 34 is a rubber part with a certain elasticity, so that soft contact is achieved between the suspension rod support 34 and the mounting seat 21, and between the suspension rod support 34 and the outer wall of the outer cylinder, thereby expanding the adjustment range of the angle between the suspension rod 3 and the box body 1 / outer cylinder, and during the adjustment process, the rod body 32 and the outer cylinder will not be damaged.

[0136] Furthermore, a buffer pad 38 is provided on the upper part of the boom support 34, and the buffer pad 38 is mounted on the vertical arm of the boom support 34. The top surface of the buffer pad 38 abuts against the bottom surface of the top plate 211, and the buffer pad 38 is an arc-shaped structure that matches the top surface of the boom support 34. The buffer pad 38 can also be a flat plate structure, and in this structure, the bottom surface of the top plate 211 can also be a plane. The buffer pad 38 can also be a rubber member with a certain elasticity, or other elastic materials.

[0137] A waterproof cap 33 is provided at a certain distance on the upper part of the vertical arm of the suspension rod support 34 to prevent the washing water measured from the washing tub 2 from falling on the shock absorbing spring 6 along the rod body 32 and the mounting hole 212, thereby causing the shock absorbing spring 6 to get damp, rust and fail.

[0138] During assembly, the rod body 32 between the waterproof cap 33 and the suspension rod support 34 is inserted from the slot 214, and the rod body 32 or the upper part of the vertical arm of the suspension rod support 34 passes through the notch 215, and is pushed inward with force to overcome the restriction of the slot 214 on the rod body 32, so that the rod body 32 is inserted into the installation hole 212, and the suspension rod support 34 enters the space surrounded by the surrounding wall 213 and the outer cylinder. Further, the buffer pad 38, the suspension rod support 34, and the spring seat 39 are all arranged in the space surrounded by the surrounding wall 213 and the outer cylinder.

[0139] After the washing machine receives the washing instruction, the controller sends a detection instruction to the detection element to determine whether the washing drum 2 is in the set initial position, that is, the washing position. If so, the controller controls the start of the washing operation according to the washing instruction; if not, the controller controls the motor 41 to drive the washing drum 2 to descend to the set initial position. After the detection element sends a message to the controller that the washing drum 2 has reached the set initial position, the controller controls the start of the washing operation.

[0140] Furthermore, a lifting program is provided in the controller, and a lifting button is provided on the control panel. When the washing program is finished, the user triggers the lifting button, the motor 41 is actuated, the bearing 43 is driven to rotate, and the screw 44 rises along the bearing 43, thereby driving the washing tub 2 to rise. A limit sensor is provided at any position in the balancing ring or the housing. When the washing tub 2 rises to a predetermined distance, the motor 41 is controlled to stop, and the washing tub 2 stops rising, so as to avoid the washing tub 2 from hitting the balancing ring and the top cover.

[0141] After the user has taken the clothes, he touches the lifting button again, and the controller controls the motor 41 to move in the reverse direction, so that the washing tub 2 returns to its original position. After the detection element detects that the washing tub 2 has been reset, it sends a signal to the controller, and the controller controls the motor 41 to stop moving;

[0142] Or if the lifting button is not provided, after the washing program is finished, the controller directly controls the motor 41 to move and drive the washing tub 2 to rise;

[0143] Furthermore, an automatic reset program may be provided. After a predetermined time has passed since the washing tub 2 has risen to its position, it is deemed that the user has taken out the clothes, and the motor 41 is controlled to move in the reverse direction to drive the washing tub 2 to reset.

[0144] Taking into account unpredictable factors such as temporary power outages and sensor failures, in this embodiment, no matter what kind of lifting, resetting procedures and devices are set, before the washing program starts, the controller will detect whether the washing drum 2 is in the set position through the detection element as described above.

[0145] In this embodiment, taking a pulsator washing machine as an example, the structure of the suspension rod 3 provided by the present invention and the assembly structure and method of the suspension rod 3, the housing 1 and the washing drum 2 as well as the specific method of driving the washing drum 2 to rise and fall in actual applications are introduced. In actual applications, the suspension rod 3 provided by the present invention and the suspension rod 3 assembly formed by the suspension rod 3, the corner fixing member 5 and the mounting seat 21 can be used in any clothing processing equipment that needs to be hoisted and adjusted in height. At the same time, it is also applicable to other washing equipment such as top-opening dishwashers.

[0146] In summary, the washing equipment suspension rod assembly and washing equipment provided by the present invention have the following beneficial effects compared with the prior art:

[0147] 1. By integrating a screw rod on the suspension rod and connecting the screw rod to the driving device, the screw rod can be lifted and lowered along the bearing in a straight line, thereby driving the washing drum to lift and lower the distance between the bottom of the washing drum and the door, making it easier for users to take items.

[0148] 2. A profiled rod body is arranged on the upper part of the boom, which cooperates with the matching structure on the fixed seat to prevent the boom from slipping between the boom and the bearing and causing rotation under the action of the motor;

[0149] 3. The matching part between the suspension rod seat and the corner fixing piece is a spherical structure, and the matching part between the suspension rod support and the mounting seat is a spherical structure, so that the angle between the suspension rod and the washing drum can be adjusted steplessly during the lifting and lowering process of the washing drum;

[0150] 4. By setting a mounting hole and a limit column larger than the diameter of the suspension rod, a space for the lateral movement of the suspension rod 3 is provided during the lifting and lowering process of the washing drum;

[0151] 5. The motor is assembled and connected to the suspension rod through a fixed base instead of being fixed directly to the box. On the one hand, it saves the internal space of the box, and on the other hand, it can prevent the vibration generated during the operation of the motor from being transmitted to the box, causing unnecessary vibration or noise.
