Description

Technical Field

[0001] The present invention relates to the technical field of household appliances, and in particular provides a weight counterweight device for a clothing processing device and the clothing processing device. Background Art

[0002] Clothes processing equipment mainly includes washing machines, shoe washers, or washer-dryers. Taking a washing machine as an example, when the washing machine performs the dehydration cycle, the washing drum usually shakes violently due to the uneven distribution of clothes in the washing drum, causing the washing machine to generate loud vibration noise.

[0003] In order to solve the above problem, a counterweight is generally added to reduce the shaking of the washing tub. However, although the existing counterweight device can reduce the shaking of the washing tub to a certain extent, the effect is not very ideal.

[0004] Accordingly, this field requires a new technical solution to solve the above problems. Summary of the Invention

[0005] In order to solve the above-mentioned problems in the prior art, that is, to solve the problem of poor vibration damping effect of the counterweight device of the existing clothing processing equipment, the present invention provides a counterweight device for clothing processing equipment, the clothing processing equipment including a box and a mounting base arranged in the box, the counterweight device including: a mass block; a magnetic component, which can be fixedly connected to the mounting base; and an elastic component, one end of which is connected to the mass block, and the other end of the elastic component is connected to the magnetic component; wherein, the magnetic component includes a first magnetic component and a second magnetic component, the second magnetic component is connected to the elastic component, and at least one of the first magnetic component and the second magnetic component is an electromagnetic component, so that the distance between the first magnetic component and the second magnetic component can be adjusted by changing the magnetic force of the first magnetic component and / or the second magnetic component, thereby adjusting the activity space of the elastic component.

[0007] In a preferred technical solution of the above-mentioned counterweight device, there are two second magnetic components, which are respectively located on both sides of the first magnetic component, and the second magnetic components are connected to the corresponding elastic components.

[0008] In the preferred technical solution of the above-mentioned counterweight device, the first magnetic component includes: a first annular body, which can be fixedly connected to the columnar structure, and a plurality of through-hole structures are formed on the first annular body along its circumference; and a plurality of first magnetic bodies, and the plurality of first magnetic bodies are located in the corresponding through-hole structures.

[0009] In the preferred technical solution of the above-mentioned counterweight device, the second magnetic component includes: a second annular body, which can move relative to the columnar structure along the axial direction of the columnar structure, and a plurality of accommodating structures are formed on the second annular body along its circumference, and the plurality of accommodating structures are arranged opposite to the through-hole structure; and a plurality of second magnetic bodies, and the plurality of second magnetic bodies are located in the corresponding accommodating structures.

[0010] In a preferred technical solution of the above-mentioned counterweight device, the first magnetic component is an electromagnetic component, the second magnetic component is a permanent magnetic component, and the magnetic poles of the two opposite ends of the permanent magnetic components are opposite.

[0011] In a preferred technical solution of the above-mentioned counterweight device, an annular groove is formed on the inner ring wall of the first annular body, and the annular groove is connected to the multiple through-hole structures.

[0012] The present invention provides a clothes processing device, which includes the counterweight device.

[0013] In the preferred technical solution of the above-mentioned clothing processing equipment, the clothing processing equipment is a drum washing machine, which further includes: a fixing device, which is arranged in the box body, and the fixing device includes a main frame; a washing drum, which is rotatably arranged in the main frame, and the washing drum is used to accommodate items to be washed and washing water, and a clothing loading port is formed at the first end of the washing drum, and the second end of the washing drum has a rotating shaft, and the rotating shaft is rotatably connected to one end of the main frame; and a water supply and drainage device, which is connected to the second end of the washing drum to supply water to the washing drum or drain the water in the washing drum; wherein the number of the counterweight devices is multiple, the main frame is the mounting base, the main frame includes a plurality of the columnar structures, and the plurality of the counterweight devices are sleeved on the corresponding columnar structures.

[0014] In the preferred technical solution of the above-mentioned clothing processing equipment, a channel is provided in the rotating shaft, and the water inlet and outlet device includes a first water inlet and outlet component, an adapter, and a second water inlet and outlet component which are connected in sequence. The first end of the first water inlet and outlet component is connected to the second end of the washing drum, and the second end of the first water inlet and outlet component is connected to the adapter via the channel. The second water inlet and outlet component is connected to the outside world. The adapter is mounted on the main frame, and the first water inlet and outlet component and the part of the adapter connected to the first water inlet and outlet component can rotate with the washing drum.

[0015] It will be understood by those skilled in the art that, in the preferred technical solution of the present invention, the counterweight device includes a mass, a magnetic component and an elastic member; wherein the magnetic component is fixedly connected to the mounting base; one end of the elastic component is connected to the mass and the other end is connected to the magnetic component; the magnetic component includes a first magnetic member and a second magnetic member, the second magnetic member is connected to the elastic member, and at least one of the first magnetic member and the second magnetic member is an electromagnetic member, which can adjust the distance between the first magnetic member and the second magnetic member by changing the magnetic force of the first magnetic member and / or the second magnetic member, thereby adjusting the active space of the elastic member. Through such an arrangement, when the active space of the elastic member becomes smaller, the elastic member is compressed, figuratively speaking, the elastic member becomes harder, and the time to recover the deformation after being compressed a fixed distance is faster. Conversely, when the active space of the elastic member becomes larger, the elastic member is released, figuratively speaking, the elastic member becomes softer, and the time to recover the deformation after being compressed a fixed distance is slower. Taking the washing machine as an example, when the washing machine executes the dehydration program, the elastic coefficient of the elastic component can be changed according to the swing amplitude of the washing drum. For example, when the swing amplitude of the washing drum is large, the elastic component is made "softer", and when the swing amplitude of the washing drum is small, the elastic component is made "harder". The frequency of the deformation change of the elastic component is adapted to the rotation frequency of the washing machine, which can greatly improve the vibration reduction effect of the counterweight device.

[0016] Furthermore, the mass block includes a cylindrical body and a plug arranged at both ends of the cylindrical body, and the first magnetic component, the second magnetic component and the elastic component are all located in the cylindrical body, wherein the cylindrical body, the plug, the first magnetic component and the second magnetic component can all be sleeved on the columnar structure on the mounting base and the cylindrical body, the plug and the second magnetic component can all move relative to the columnar structure along the axial direction of the columnar structure; wherein the elastic component includes two elastic components and is respectively located on both sides of the first magnetic component, and the two elastic components can extend or contract along the axial direction of the columnar structure. Through such an arrangement, that is, by adopting a mass block of a cylindrical body and arranging the first magnetic component, the second magnetic component and the elastic component in the cylindrical body, the stability of the counterweight device can be improved, and the noise reduction effect of the counterweight device can be improved and the safety protection and aesthetics can be enhanced.

[0017] Furthermore, there are two second magnetic members, one located on either side of the first magnetic member, connected to the corresponding elastic member. This arrangement allows the two second magnetic members to adjust the elastic deformation of the corresponding elastic member, ensuring symmetry between the two sides of the first magnetic member and further improving the vibration reduction effect of the counterweight device.

[0018] Furthermore, the first magnetic component includes: a first annular body that can be fixedly connected to the columnar structure, the first annular body having a plurality of through-hole structures formed along its circumference; and a plurality of first magnetic bodies, the plurality of first magnetic bodies being located within corresponding through-hole structures; and / or the second magnetic component includes: a second annular body that can move relative to the columnar structure in an axial direction, the second annular body having a plurality of receiving structures formed along its circumference, the plurality of receiving structures being arranged opposite to the through-hole structures; and a plurality of second magnetic bodies, the plurality of second magnetic bodies being located within corresponding receiving structures. Through such an arrangement, the mutual effective force between the first magnetic component and the second magnetic component can be enhanced to maximize the effect.

[0019] Furthermore, the first magnetic member is an electromagnetic member, and the second magnetic member is a permanent magnet, with the magnetic poles of the two permanent magnets at opposite ends being opposite. This arrangement ensures that the electromagnetic force generated by the electromagnetic member is balanced with the interaction force generated by the two permanent magnets on either side, thereby maintaining the first magnetic member in a position to move left and right within the center of the inner cavity.

[0020] Furthermore, an annular groove is formed on the inner wall of the first annular body, which is connected to the multiple through-hole structures. This arrangement allows the wires of the multiple electromagnets installed on the first annular body to be routed centrally through the groove and then led out through the through-hole structures, ensuring safe and reliable connection of the wires.

[0021] In addition, the clothing processing equipment further provided by the present invention on the basis of the above technical solution has the technical effects of the above counterweight device due to the adoption of the above counterweight device. Compared with the existing clothing processing equipment, the clothing processing equipment of the present invention has less vibration and noise during operation. BRIEF DESCRIPTION OF THE DRAWINGS

These are merely for ease of description and do not indicate or imply that the device or component described must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on the present invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0041] Furthermore, it should be noted that, in the description of the present invention, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed connections, detachable connections, or integral connections; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0042] First refer to Figures 1 to 3 ,in, Figure 1 This is a schematic diagram of the structure of the drum washing machine of the present invention. Figure 1 ; Figure 2 This is a schematic diagram of the structure of the drum washing machine of the present invention. Figure 2 ; Figure 3 This is a schematic diagram of the structure of the drum washing machine of the present invention. Figure 3 .

[0043] like Figures 1 to 3 As shown, the drum washing machine of the present invention comprises a housing 1, in which a fixing device, a washing tub 2, a driving device, a water supply and drainage device, a vibration reduction and damping device and a counterweight device are arranged.

[0044] Continue reading Figures 1 to 3 The washing tub 2 is used to accommodate items to be washed and washing water. The first end of the washing tub 2 (from Figure 1 A clothing inlet 211 is formed at the left end of the washing drum 2 (seen from above), through which the user can put the clothes to be washed into the washing drum 2 and take the washed clothes out of the washing drum 2 through the clothing inlet 211.

[0045] Continue reading Figures 1 to 3 The washing drum 2 is rotatably arranged in the fixing device, and the driving device is connected to the second end of the washing drum 2 (from Figure 1 The washing machine is driven by the washing machine 31 (seeing from above, the right end of the washing drum 2). When the washing machine is running, the driving device can drive the washing drum 2 to rotate. The second end of the washing drum 2 has a rotating shaft 22, and the washing drum 2 is rotatably connected to the fixing device via the rotating shaft 22. For example, the driving device includes a motor 31, a belt 32, and a pulley 33. The pulley 33 is fixedly connected to the rotating shaft 22, and one end of the belt 32 is connected to the output shaft of the motor 31. The output shaft of the motor 31 is generally equipped with a small pulley. One end of the belt 32 is connected to the small pulley, and the other end of the belt 32 is connected to the pulley 33 installed on the rotating shaft 22. The motor 31 drives the pulley 33 and the rotating shaft 22 to rotate via the belt 32.

[0046] It should be noted that the driving device is not limited to the specific examples mentioned above. For example, a direct drive motor can also be used for driving. The stator device of the direct drive motor can be installed on the fixing device, and the rotor of the direct drive motor can be installed on the rotating shaft 22. Such adjustments and changes to the specific structural form of the driving device do not deviate from the principles and scope of the present invention and should be limited within the scope of protection of the present invention.

[0047] Continue reading Figures 1 to 3 The water supply and drainage device is connected to the second end of the washing tub 2, and water can be supplied to the washing tub 2 or the water in the washing tub 2 can be drained through the water supply and drainage device.

[0048] Continue reading Figures 1 to 3 The vibration damping device is disposed between the fixing device and the housing 1. The vibration damping device reduces vibrations to reduce the vibration noise of the washing machine. The vibration damping device includes a suspension spring 41 and a damper 42. The top of the fixing device is fixedly connected to the housing 1 via the suspension spring 41, and the bottom of the fixing device is fixedly connected to the housing 1 via the damper 42.

[0049] Continue reading Figures 1 to 3 , and then see Figure 4 , Figure 4 It is a structural schematic diagram of a fixing device of a drum washing machine of the present invention.

[0050] like Figures 1 to 4 As shown, the fixing device includes a main frame 51, the washing drum 2 is rotatably arranged in the main frame 51, and the rotating shaft 22 is connected to the rear end of the main frame 51 (from Figure 1 By installing the washing tub 2 in the main frame 51, a portion of the washing tub 2 can be extended to the outside of the main frame 51 (such as the right end of the main frame 51). Figure 2 and Figure 3 As shown), in this way, the size of the washing drum 2 can be expanded as much as possible, thereby increasing the washing capacity of the washing machine without changing the external dimensions.

[0051] Continue reading Figure 4 A support structure is provided at the rear end of the main frame 51, and the rotating shaft 22 is rotatably connected to the support structure. The supporting structure is a cylindrical structure 511. The rotating shaft 22 can be inserted into the cylindrical structure 511, and the two are connected by a bearing so that the rotating shaft 22 can rotate relative to the cylindrical structure 511.

[0052] Continue reading Figure 2 and Figure 4 The fixing device further includes a plurality of rollers 52 disposed on the main frame 51. When fully installed, the plurality of rollers 52 abut against the outer wall of the washing tub 2. For example, the main frame 51 includes four crossbeams 512 arranged along the axial direction of the washing tub 2. Each crossbeam 512 is mounted with a roller 52, and the rollers 52 are disposed near the first end of the main frame 51. By providing the rollers 52 to support the first end of the washing tub 2, the pressure exerted on the rotating shaft 22 by the second end of the washing tub 2 can be greatly reduced, thereby reducing the design difficulty and processing cost of the rotating shaft 22 and extending the service life of the rotating shaft 22.

[0053] Continue reading Figure 4 The main frame 51 includes two accommodating areas, which are arranged in a vertical direction, and are recorded as an upper accommodating area 513 and a lower accommodating area 514, wherein the washing drum 2 is located in the upper accommodating area 513.

[0054] Next see Figure 5 , Figure 5 It is a schematic structural diagram of a washing drum of a drum washing machine of the present invention.

[0055] like Figure 5 As shown, a water passage structure is formed at the second end of the washing drum 2, and the water inlet and outlet device is connected to the water passage structure. Through the water passage structure, water can be supplied into the washing drum 2 or the water in the washing drum 2 can be drained. Preferably, the water passage structure is a water passage 212 formed at the junction of the rear wall and the inner wall of the washing drum 2. By arranging the water passage 212 at the junction of the rear wall and the inner wall, it is more convenient to drain the water in the washing drum 2.

[0056] Continue reading Figure 5 A water collecting ring 213 is formed on the inner wall of the washing tub 2 and is connected to the water inlet 212. As can be seen from the figure, the water collecting ring 213 is a groove-like structure on the inner wall of the washing tub 2, convex outward along the radial direction of the washing tub 2, so that the bottom of the water collecting ring 213 is lower than the inner wall of the washing tub 2. In this way, the water in the washing tub 2 will gather in the water collecting ring 213, which is conducive to draining the water in the washing tub 2.

[0057] Continue reading Figure 5 A plurality of water guide structures are provided on the inner wall of the washing tub 2. The water guide structures extend along the axial direction of the washing tub 2, and the rear end of the water guide structures (from Figure 5 The right end of the water guide structure (as seen from above) is connected to the water collection ring 213. Providing a water guide structure on the inner wall of the washing drum 2 facilitates the collection of water within the washing drum 2 toward the water collection ring 213. This is particularly true when the washing drum 2 is rotating, such as when the washing machine is performing a spin cycle. Water on the inner wall is unobstructed by clothing and flows directly and rapidly toward the water collection ring 213 along the water guide structure, significantly improving the washing machine's spin cycle.

[0058] Continue reading Figure 5 The water-guiding structure is a water-guiding groove 214 formed on the inner wall of the washing tub 2. In other words, the water-guiding structure is a strip-shaped groove-like structure that protrudes outward along the radial direction of the washing tub 2 on the inner wall of the washing tub 2. Of course, multiple inwardly protruding strip-shaped ribs can also be formed on the inner wall of the washing tub 2 along the radial direction of the washing tub 2. In this way, a water-guiding structure can also be formed between two adjacent strip-shaped ribs. Preferably, the water-guiding groove 214 can be combined with the strip-shaped ribs, with the two structures arranged at intervals to further improve drainage efficiency.

[0059] Continue reading Figure 5As can be seen from the figure, some water guide grooves 214 are longer, some are shorter, and the two different lengths of water guide grooves 214 are arranged at intervals, that is, the lengths of two adjacent water guide grooves 214 are different. Because the rear ends of the water guide grooves 214 need to be connected to the water collecting ring 213, the longer water guide groove 214 extends to the first end of the washing tub 2 longer than the shorter water guide groove 214, dividing the washing tub 2 into a front section, a middle section, and a rear section along the axial direction of the washing tub 2. Figure 5 It can be seen that the water guide grooves 214 located at the front section of the washing drum 2 are relatively sparse, and the water guide grooves 214 located at the middle section and the rear section of the washing drum 2 are relatively dense. By using such water guide grooves 214 of different lengths, the processing cost can be reduced as much as possible while ensuring that the drainage needs of the washing machine are met.

[0060] Continue reading Figure 5 The inner diameter of the first end of the washing tub 2 is smaller than the inner diameter of the second end of the washing tub 2. By such an arrangement, it is more conducive to the water in the washing tub 2 flowing toward the water inlet 212.

[0061] Continue reading Figures 1 to 5 , and then see Figures 6 to 8 ,in, Figure 6 1 is a schematic diagram of the assembly of the first water pipe and the water collecting member of the drum washing machine of the present invention; Figure 7 2 is a schematic structural diagram of a water collecting member of a drum washing machine of the present invention; Figure 8 It is a schematic diagram of the assembly of the rotating shaft, the cylindrical structure and the adapter of the drum washing machine of the present invention.

[0062] like Figure 1 、 Figure 3 、 Figure 6 and Figure 8 As shown, the water inlet and outlet device includes a first water inlet and outlet assembly, an adapter, and a second water inlet and outlet assembly which are connected in sequence, wherein the first water inlet and outlet assembly is connected to a water outlet 212 formed at the second end of the washing tub 2, that is, the first water inlet and outlet assembly does not need to extend into the interior of the washing tub 2, and the second water inlet and outlet assembly is connected to the outside world, and the adapter is installed on a tubular structure 511 arranged at the rear end of the fixing device.

[0063] When the washing tub 2 rotates, the first water inlet and drain assembly and the portion of the adapter connected to the first water inlet and drain assembly can rotate with the washing tub 2, and the second water inlet and drain assembly and the portion of the adapter connected to the second water inlet and drain assembly are fixed.

[0064] That is to say, the water inlet and outlet device includes three core structures, namely, a first water inlet and outlet assembly connected to the washing drum 2, a second water inlet and outlet assembly connected to the outside world, and an adapter for connecting the first water inlet and outlet assembly and the second water inlet and outlet assembly. The key to the three core structures lies in the adapter. Specifically, the adapter itself includes two parts, the first part is connected to the first water inlet and outlet assembly, and the second part is connected to the second water inlet and outlet assembly. The two parts of the adapter can rotate relative to each other, and the second part is installed on the fixing device. In this way, when the washing drum 2 rotates, the first water inlet and outlet assembly and the first part of the adapter can rotate with the washing drum 2. The second water inlet and outlet assembly is connected to the outside world and needs to remain fixed.

[0065] Continue reading Figure 1 、 Figure 3 and Figure 8 The adapter is preferably configured as a rotating tee 64, which includes a rotating port 641 and a fixed port 642, wherein the rotating port 641 is connected to the first water inlet and outlet assembly and can rotate with the first water inlet and outlet assembly. There are two fixed ports 642, and the second water inlet and outlet assembly includes an inlet pipe 65 and a drain pipe 66. One of the two fixed ports 642 is a water inlet, which is connected to the water inlet pipe 65, and the other end of the water inlet pipe 65 is connected to an external water supply source. The other fixed port 642 is a water outlet, which is connected to the drain pipe 66, and the other end of the drain pipe 66 is connected to a drainage pump 67.

[0066] Continue reading Figures 5 to 8 The first water inlet and outlet assembly includes a first water pipe 61, a water collecting member 62, and a connecting pipe 63 that are connected in sequence, wherein the number of first water pipes 61 can be multiple. For example, the number of first water pipes 61 is three, and accordingly, the number of water outlets is also three. The three water outlets 212 are arranged along the circumference of the washing tub 2. The first end of the first water pipe 61 is connected to the corresponding water outlet 212. One end of the water collecting member 62 is provided with a water diversion port 621, and the number of water diversion ports 621 is three. The second end of the first water pipe 61 is connected to the corresponding water diversion port 621. The other end of the water collecting member 62 is provided with a central port (not shown in the figure). The multiple water diversion ports 621 are all connected to the central port. The central port of the water collecting member 62 is then connected to the rotating port 641 of the rotating tee 64 through the connecting pipe 63. In this way, the three first water pipes 61 are connected to the rotating tee 64 through the water collecting member 62 and the connecting pipe 63.

[0067] The three first water pipes 61 are connected through the water collecting part 62. When draining, the water can be drained through the three first water pipes 61 at the same time. Similarly, when filling water, the water can be filled through the three first water pipes 61 at the same time. Through such an arrangement, the water filling and drainage capacity of the washing machine can be greatly improved and the washing time can be reduced.

[0068] It should be noted that, in actual applications, those skilled in the art can cancel the connection pipe 63 as needed and directly connect the water collecting part 62 with the rotating tee 64. Such flexible adjustment and change does not deviate from the principle and scope of the present invention and should be limited within the scope of protection of the present invention.

[0069] Continue reading Figure 8 A channel 221 is provided in the rotating shaft 22, and the first water inlet and outlet assembly is connected to the rotating tee 64 via the channel 221 and the cylindrical structure 511. The inner diameter of the channel 221 can be larger than the outer diameter of the cylindrical structure 511. In this case, during installation, the cylindrical structure 511 can be inserted into the channel 221 of the rotating shaft 22; conversely, the inner diameter of the cylindrical structure 511 can be larger than the outer diameter of the rotating shaft 22. In this case, during installation, the rotating shaft 22 can be inserted into the cylindrical structure 511. Preferably, the inner diameter of the channel 221 is larger than the outer diameter of the cylindrical structure 511. During installation, the cylindrical structure 511 is inserted into the channel 221 of the rotating shaft 22. The two are connected by a bearing 24 so that they can rotate relative to each other.

[0070] Continue reading Figure 5 and Figure 8 , and then see Figure 9 , Figure 9 It is a structural schematic diagram of the connecting components of the drum washing machine of the present invention.

[0071] like Figure 5 、 Figure 8 and Figure 9 As shown, the washing drum 2 includes a drum body 21, a rotating shaft 22 and a connecting member 23, wherein the drum body 21 is used to accommodate items to be washed and washing water, a clothing inlet 211, a water outlet 212, a water collecting ring 213 and a water guide groove 214 are all formed on the drum body 21, and one end of the connecting member 23 is connected to the second end of the drum body 21 (from Figure 5 The other end of the connecting member 23 is connected to the rotating shaft 22. In other words, the rotating shaft 22 is fixedly connected to the cylindrical body 21 through the connecting member 23. When the driving device drives the rotating shaft 22 to rotate, the rotating shaft 22 drives the cylindrical body 21 to rotate synchronously through the connecting member 23.

[0072] The connecting member 23 includes a connected fixed cylinder 231 and a connecting arm 232, wherein the number of the connecting arms 232 is multiple, exemplarily, the number of the connecting arms 232 is three, and the three connecting arms 232 are arranged along the circumference of the fixed cylinder 231, preferably evenly arranged along the circumference of the fixed cylinder 231. The connecting arm 232 and the fixed cylinder 231 can be fixedly connected or integrally arranged. During installation, the rotating shaft 22 can be inserted into the fixed cylinder 231, and the two can adopt an interference fit or a clearance fit. If a clearance fit is adopted, the rotating shaft 22 and the fixed cylinder 231 can be circumferentially fixed by a key. Exemplarily, a first keyway is formed on the inner wall of the fixed cylinder 231, and a second keyway is formed on the outer wall of the rotating shaft 22. The first keyway and the second keyway are circumferentially fixed by a key. Of course, the rotating shaft 22 and the fixed cylinder 231 preferably adopt an interference fit to improve the stability of the connection between the two.

[0073] Continue reading Figure 5 、 Figure 8 and Figure 9 When installed, the connecting arm 232 is fixedly connected to the second end of the cylinder 21, the rotating shaft 22 is fixedly connected to the fixed cylinder 231 of the connecting member 23, and there is a certain gap between the end of the rotating shaft 22 and the second end of the cylinder 21. The second end of the first water pipe 61 can enter the channel 221 of the rotating shaft 22 through the gap.

[0074] Specifically, when installed, the water collecting part 62 can be fixed on the fixed cylinder 231 of the connecting member 23, so that the water collecting part 62 is located in the gap between the rotating shaft 22 and the cylinder 21, and the water diversion port 621 of the water collecting part 62 is facing the cylinder 21, and the central port of the water collecting part 62 is facing the channel 221 of the rotating shaft 22. In this way, the second end of the first water pipe 61 can be directly connected to the corresponding water diversion port 621, the connecting pipe 63 is located inside the channel 221 and the cylindrical structure 511, the central port of the water collecting part 62 is connected to the left end of the connecting pipe 63, the rotating tee 64 is fixed on the cylindrical structure 511, and the rotating port 641 of the rotating tee 64 is extended into the cylindrical structure 511, and the right end of the connecting pipe 63 is connected to the rotating port 641. The rotating port 641 of the rotating tee 64, the connecting pipe 63, the water collecting part 62 and the first water pipe 61 can rotate synchronously with the cylinder 21. Of course, the water collecting member 62 may also be fixedly connected to the rotating shaft 22 and installed in the channel 221 of the rotating shaft 22 .

[0075] The three first water pipes 61 can simultaneously take in water and drain water. During drainage, in order to prevent air leakage, the washing tub 2 can be kept rotating. Under the action of centripetal force, the washing water is evenly distributed along the water collecting ring 213, so that all three water inlets 212 are immersed in water, thereby improving the drainage capacity of the washing machine and reducing the washing time.

[0076] Continue reading Figure 9 The three connecting arms 232 have the same structure. For example, one of the connecting arms 232 includes a strip 2321 and a reinforcement 2322. There are two strips 2321, spaced apart, and fixedly connected or integrally formed with the fixing tube 231. There are multiple reinforcements 2322, exemplarily two, with each end of the reinforcement 2322 fixedly connected or integrally formed with the two strips 2321. When properly installed, the first water pipe 61 can be positioned in the gap between the two strips 2321 and fixedly connected to the reinforcement 2322, thereby preventing movement.

[0077] Continue reading Figure 4 , and then see Figure 10 ,in, Figure 10 It is a structural schematic diagram of the counterweight device of the present invention.

[0078] like Figure 4 and Figure 10 As shown, the counterweight device of the present invention is installed on the main frame 51, that is, the main frame 51 is used as the installation base, the main frame 51 includes multiple columnar structures, the number of counterweight devices is multiple, and multiple counterweight devices are mounted on corresponding columnar structures.

[0079] Exemplarily, the multiple columnar structures include multiple columns 515 and multiple beams 512, and multiple counterweight devices are respectively mounted on the columns 515 and the beams 512. It should be noted that the beams 512 include beams 512 extending along the axial direction of the washing drum 2 and beams 512 perpendicular to the axial direction of the washing drum 2. It is preferred that the counterweight device is installed only on the beams 512 perpendicular to the axial direction of the washing drum 2.

[0080] It should also be noted that the counterweight device of the present invention can also be directly installed on the washing drum 2 of an ordinary washing machine. Such adjustment of the specific installation position of the counterweight device does not deviate from the principle and scope of the present invention and should be limited within the scope of protection of the present invention.

[0081] The following describes the counterweight device of the present invention by taking a counterweight device installed on a column 515 as an example.

[0082] like Figure 10As shown, the counterweight device of the present invention includes a mass block 71, an elastic component and a magnetic component, the magnetic component is fixedly connected to the column 515, one end of the elastic component is connected to the mass block 71, and the other end of the elastic component is connected to the magnetic component; wherein, the magnetic component includes a first magnetic component 72 and a second magnetic component 73, the second magnetic component 73 is connected to the elastic component, and at least one of the first magnetic component 72 and the second magnetic component 73 is an electromagnetic component, so that the distance between the first magnetic component 72 and the second magnetic component 73 can be adjusted by changing the magnetic force of the first magnetic component 72 and / or the second magnetic component 73, thereby adjusting the activity space of the elastic component.

[0083] Exemplarily, the first magnetic component 72 is an electromagnetic component, and the second magnetic component 73 is a permanent magnetic component. The controller of the washing machine can be used to control the power on or off of the first magnetic component 72 and the magnitude and direction of the current when it is powered on. When the first magnetic component 72 is powered on, the first magnetic component 72 generates a magnetic force, and the magnetic poles of the first magnetic component 72 and the second magnetic component 73 at the opposite ends are the same. For example, the magnetic pole of the end of the first magnetic component 72 facing the second magnetic component 73 is the N pole, and the magnetic pole of the end of the second magnetic component 73 facing the first magnetic component 72 is also the N pole. In this way, when the first magnetic component 72 is powered on, the first magnetic component 72 generates a magnetic force. Component 72 and the second magnetic component 73 repel each other, the second magnetic component 73 moves away from the first magnetic component 72, and the distance between the first magnetic component 72 and the second magnetic component 73 becomes larger. Correspondingly, the activity space of the elastic component becomes smaller, the elastic component is compressed, the elasticity becomes worse, and it appears to be harder. When the first magnetic component 72 is powered off, the magnetic force of the first magnetic component 72 disappears. Under the action of the elastic component, the second magnetic component 73 is reset, and the distance between the first magnetic component 72 and the second magnetic component 73 becomes smaller. Correspondingly, the activity space of the elastic component becomes larger, the elastic component is released, and the elastic coefficient becomes smaller.

[0084] It should be noted that the first magnetic member 72 can also be set as a permanent magnetic member and the second magnetic member 73 can be set as an electromagnetic member, or the first magnetic member 72 and the second magnetic member 73 can both be set as electromagnetic members. Such flexible adjustment and change does not deviate from the principles and scope of the present invention and should be limited within the scope of protection of the present invention. Of course, it is preferred that the first magnetic member 72 is an electromagnetic member and the second magnetic member 73 is a permanent magnetic member.

[0085] The following continues to describe the weight balancing device of the present invention by taking the first magnetic component 72 as an electromagnetic component and the second magnetic component 73 as a permanent magnetic component as an example.

[0086] like Figure 10As shown, the mass block 71 includes a cylindrical body 711 and a plug 712 arranged at both ends of the cylindrical body 711, and the first magnetic component 72, the second magnetic component 73 and the elastic component are all located in the cylindrical body 711, wherein the cylindrical body 711, the plug 712, the first magnetic component 72 and the second magnetic component 73 can all be sleeved on the column 515, and the cylindrical body 711, the plug 712 and the second magnetic component 73 can all move relative to the column 515 along the axial direction of the column 515; wherein the elastic component includes two elastic components 74 and is respectively located on both sides of the first magnetic component 72, and the two elastic components 74 can extend or contract along the axial direction of the column 515; the number of the second magnetic components 73 is two and is respectively located on both sides of the first magnetic component 72, and the second magnetic component 73 is connected to the corresponding elastic components 74.

[0087] There are two plugs 712, one is located at the bottom end of the cylindrical body 711. Exemplarily, the plug 712 is integrated with the cylindrical body 711, and the other is located at the top end of the cylindrical body 711. The plug 712 is detachably connected to the cylindrical body 711. Exemplarily, the plug 712 is threadedly connected to the cylindrical body 711. For example, an internal thread can be formed on the inner wall of the cylindrical body 711, and correspondingly, an external thread is formed on the outer wall of the plug 712, and the internal thread is adapted to the external thread.

[0088] The two second magnetic components 73 are respectively located on the upper and lower sides of the first magnetic component 72, and the two elastic components 74 are also respectively located on the upper and lower sides of the first magnetic component 72, and the two ends of the two elastic components 74 are respectively fixedly connected to the corresponding blockages 712 and the second magnetic components 73. In addition, the magnetic poles of the opposite ends of the two second magnetic components 73 are opposite. In this way, when the first magnetic component 72 is energized, it can repel each other with the two second magnetic components 73. For example, the magnetic pole at the top of the lower second magnetic component 73 is the S pole, and the magnetic pole at the bottom of the upper second magnetic component 73 is the N pole. After the first magnetic component 72 is energized, the magnetic pole at the bottom of the first magnetic component 72 is the S pole, and the magnetic pole at the top is the N pole, which generates a repulsive force with the two second magnetic components 73, thereby causing the lower second magnetic component 73 to move downward, compressing the lower elastic component 74, and causing the upper second magnetic component 73 to move upward, compressing the upper elastic component 74.

[0089] The elastic member 74 is preferably a spring. When compressed, the spring becomes stiffer and rebounds faster after further compression or stretching. When the washing drum 2, loaded with clothes, rotates, the centripetal force causes the washing drum 2 to drive the main frame 51 to tilt toward the eccentric side. At this time, objects fixed to the washing drum 2 and the main frame 51 will also tilt accordingly. Although the main frame 51 has a certain mass as a whole, and its inertia will reduce some of the tilt, it cannot be completely avoided. As the rotation speed increases and the centripetal force increases, the tilt increases, and the periodic left and right and up and down tilts generate vibration.

[0090] When the washing tub 2 tilts rapidly to one side, since the mass block 71 of the counterweight device is movably connected to the column 515 of the main frame 51, the mass block 71 has a large mass and tends to remain stationary under the action of inertia, while the column 515 of the main frame 51 is displaced. At this time, one of the springs is compressed and the other is stretched. The elastic force generated by the compression restrains the column 515, preventing it from expanding its displacement, thereby weakening the vibration. Moreover, the greater the elasticity of the spring, the stronger its ability to weaken the vibration. This can be achieved by controlling the power supply of the first magnetic member 72 or the current. The elastic coefficient of the spring can be changed by adjusting the size of the spring. For example, at the beginning of dehydration, the moisture content is the highest and the eccentricity is the most serious. At this time, the first magnetic member 72 is not energized, and only the fixed spring is used to restrain the vibration. After a short operation, the speed increases, the moisture content decreases, and the vibration frequency increases. The first magnetic member 72 can be energized and the current can be gradually increased to generate a repulsive force on the two second magnetic members 73 to increase the hardness of the spring. In other words, the spring can recover faster after being squeezed and deformed by the eccentric action, so that it matches the rotation frequency of the washing drum 2, which can minimize vibration and noise.

[0091] It should be noted that if it is necessary to install the counterweight device on the washing drum 2, a columnar structure can be provided on the washing drum 2, and the counterweight device described above can be sleeved on the columnar structure, or a chute structure can be provided on the washing drum 2, and the structural form of the counterweight device can be adjusted accordingly. For example, the mass block 71 can be set as a slider structure that is compatible with the chute structure, and the number of the first magnetic member 72, the second magnetic member 73 and the elastic member 74 are two, divided into two groups, and are respectively located on the left and right sides of the mass block 71, the first magnetic member 72 is fixedly connected to the washing drum 2, and the two ends of the elastic member 74 are respectively fixedly connected to the second magnetic member 73 and the mass block 71, and so on. Such flexible adjustment and change do not deviate from the principle and scope of the present invention, and should be limited within the scope of protection of the present invention. Of course, it is preferred to adopt the above-mentioned structural form of sleeved counterweight device on the main frame 51.

[0092] Continue reading Figure 10 , and then see Figure 11 and Figure 12,in, Figure 11 is a schematic structural diagram of the first magnetic member 72 of the counterweight device of the present invention; Figure 12 yes Figure 11 Cross-sectional view at AA in the middle.

[0093] like Figures 10 to 12 As shown, the first magnetic component 72 includes a first annular body 721 and a plurality of first magnetic bodies (not shown in the figure), wherein the first annular body 721 is fixedly connected to the column 515, and a plurality of through-hole structures 7211 are formed on the first annular body 721 along its circumference, and the plurality of first magnetic bodies are located in the corresponding through-hole structures 7211, and the first magnetic body is an electromagnet.

[0094] Continue reading Figures 10 to 12 The first annular body 721 is preferably fixed to the column 515 by a snap-fit ​​method. For example, the drum washing machine further includes an elastic snap-fit ​​pin 8. The column 515 is a hollow structure with a first limiting hole formed therein. The first annular body 721 is formed with a second limiting hole. The elastic snap-fit ​​pin 8 is located within the column 515 and is snap-fitted to the first and second limiting holes.

[0095] Continue reading Figures 10 to 12 An annular groove 7212 is formed on the inner wall of the first annular body 721. The annular groove 7212 is connected to the plurality of through-hole structures 7211. The wire harness 722 of the electromagnet located within the through-hole structures 7211 can be wound within the annular groove 7212. In addition, the column has a through-hole formed at a position corresponding to the annular groove 7212, and the wire harness 722 can be introduced into the column 515 through the through-hole.

[0096] Continue reading Figure 10 , and then see Figure 13 and Figure 14 ,in, Figure 13 is a schematic structural diagram of the second magnetic member 73 of the counterweight device of the present invention; Figure 14 yes Figure 13 Cross-sectional view at the middle BB.

[0097] like Figure 10 、 13 As shown in Figures 14 and 14, the second magnetic component 73 includes a second annular body 731 and a plurality of second magnetic bodies 732. The second annular body 731 is sleeved on the column 515 and can move up and down relative to the column 515 along the axial direction of the column 515. A plurality of accommodating structures 7311 are formed on the second annular body 731 along its circumference. The plurality of second magnetic bodies 732 are located in the corresponding accommodating structures 7311. The plurality of accommodating structures 7311 are arranged relative to the through-hole structure 7211 so that the second magnetic body 732 is opposite to the first magnetic body, wherein the second magnetic body 732 is a permanent magnet.
