Description

TECHNICAL FIELD

[0001] The embodiment of the application relates to the washing machine packaging technical field, and particularly relates to a packaging of a pulsator washing machine and a pulsator washing machine assembly. BACKGROUND

[0002] As a mainstream product of household washing equipment, the pulsator washing machine relies on the periodic forward and reverse movement of the bottom pulsator. In the washing process, the pulsator generates centrifugal water flow through motor driving to realize cleaning by friction with clothes. The structural feature makes it necessary to configure heavy motors (usually 5-8 kg), speed reducers, clutches and counterweights in the washing machine.

[0003] In the related art, a customized mold forming packaging structure is usually used to fix and protect the pulsator washing machine. Since such packaging needs to be accurately matched with the shape size and structural features of the pulsator washing machine to ensure the buffering effect, a special mold needs to be designed and manufactured for different models, and the packaging production is completed through processes such as injection molding, foaming or hot pressing. However, the mold adaptability of this technical solution is poor, and the production efficiency is low.

[0004] Therefore, the application is proposed. CONTENT OF THE UTILITY MODEL

[0007] The cabinet is configured as an external shell of the pulsator washing machine. The cabinet comprises a shell and a surrounding frame. The surrounding frame is arranged at the top of the shell. The shell comprises a first accommodating portion. The first accommodating portion is arranged at the bottom position of the back of the shell and is formed by extending outward from the inside of the shell.

[0008] The packaging of the pulsator washing machine comprises a bottom cover, a corner guard and a top cover. One end of the corner guard is connected with the top cover, and one end of the corner guard is connected with the bottom cover. The top cover, the bottom cover and the corner guard surround to form a containing area for containing the washing machine.

[0009] The bottom cover further comprises a bottom cover body which is formed by at least the avoiding fold plate.

[0010] The bottom cover body comprises a supporting bottom plate and a bottom cover side wall. The bottom cover side wall surrounds the edge of the supporting bottom plate and is connected with the supporting bottom plate.

[0011] The bottom cover side wall comprises at least one first avoiding structure, which is formed on the inner side of the bottom cover side wall, and the first avoiding structure cooperates with the first accommodating part;

[0012] The avoiding foldable plate comprises at least one first avoiding groove, at least part of the first avoiding groove forms the first avoiding structure after the avoiding foldable plate is folded.

[0013] By setting the avoiding foldable plate as a flush and hollow structure, cutting the first avoiding groove at the corresponding position of the avoiding foldable plate, and bending the hollow overhanging part backward to form the first avoiding structure, the complicated mold is not needed, the process is simplified, the production efficiency of the bottom cover is improved, and the material is saved.

[0014] In some embodiments, the impeller washing machine comprises a guide rib, which is arranged at the bottom of the shell and used for mounting the rat guard;

[0015] The bottom cover further comprises a second avoiding structure, which cooperates with the guide rib, and the second avoiding structure is formed by extending inward from the top surface of the bottom cover body.

[0016] The second avoiding structure and the guide rib cooperate to stabilize the machine box of the impeller washing machine to some extent, and effectively improve the stability of the installation of the impeller washing machine during transportation.

[0017] In some embodiments, the second avoiding structure is arranged in a plurality of forms, and the plurality of second avoiding structures are arranged at intervals.

[0018] By arranging the second avoiding structures with different shapes and sizes, the second avoiding structures can be applied to impeller washing machines of different models.

[0072] With reference to the drawings of the embodiments of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of the present application.

[0073] The present application provides a packaging 200 of a pulsator washing machine. Referring to Figure 1 The assembly schematic diagram between the pulsator washing machine 100 and the packaging 200 of the pulsator washing machine is shown. The structure of the pulsator washing machine 100 will be further described below.

[0074] The pulsator washing machine 100 comprises a cabinet 10. The cabinet 10 is the external shell of the pulsator washing machine 100. The top of the cabinet 10 has a clothes loading and unloading opening.

[0075] The cabinet 10 comprises a shell 11 and a surrounding frame 12. The surrounding frame 12 is arranged on the top of the shell 11, and the surrounding frame 12 has a clothes loading opening in communication with the inside of the shell 11.

[0076] The pulsator washing machine comprises a door cover 40 arranged at the clothes loading opening for opening or closing the clothes loading opening.

[0077] The pulsator washing machine 100 comprises a drum assembly comprising an inner drum and an outer drum. The inner drum has a clothes washing cavity. The outer drum is arranged in the shell 11. The inner drum is arranged in the outer drum, and the drum opening of the inner drum faces the clothes loading opening and is in communication with the clothes loading opening.

[0078] The pulsator washing machine 100 comprises a motor system located at the bottom of the pulsator washing machine 100. The pulsator washing machine 100 comprises a pulsator disc. The pulsator disc is arranged at the bottom of the inner drum and is connected to the motor system through a transmission shaft.

[0079] During the process of washing clothes, the motor system drives the pulsator disc to rotate to wash the clothes in the clothes washing cavity.

[0080] In some embodiments, the shell comprises a first accommodating portion arranged at the bottom of the back of the shell. The first accommodating portion is formed by extending from the inside of the shell to the outside.

[0081] The first accommodating portion is arranged as a structure protruding to the outside of the shell. The first accommodating portion can be used to accommodate internal pipelines, water pipes and the like.

[0082] In some embodiments, the shell comprises a second accommodating portion. The second accommodating portion is arranged at the bottom of the shell. The second accommodating portion is formed by recessing inwardly from the bottom surface of the shell.

[0083] In some embodiments, the pulsator washing machine includes support legs. The support legs are disposed on the bottom surface of the housing. In some possible embodiments, four support legs are provided, with the four support legs respectively disposed at the four corners of the bottom surface of the housing.

[0084] During transportation, the pulsator washing machine 100 is inevitably subject to bumps and drops, which can cause damage. In order to reduce the damage to the pulsator washing machine 100 during transportation, in related technologies, a packaging box is provided on the outside of the casing 10 of the pulsator washing machine 100 to protect the casing 10.

[0085] Currently, packaging materials for boxes are mostly made of expanded polystyrene (EPS) foam or expanded polypropylene (EPP) foam. EPS foam is formed by foaming EPS particles, and EPP foam is formed by foaming EPP particles. Their production process generates a large amount of flammable gases, posing high safety hazards and being environmentally unfriendly. Moreover, EPS and EPP foams are difficult to recycle and reuse after use; most used EPS foam is incinerated or discarded, causing significant harm to the environment.

[0086] To address the aforementioned issues, related technologies employ cardboard packaging to encapsulate the pulsator washing machine 100. However, cardboard has poor water resistance; its structural strength rapidly decreases after becoming damp, making it difficult to effectively protect the pulsator washing machine 100 and reducing the protective performance of the packaging.

[0087] In view of this, the packaging of the present application embodiment uses plastic parts made of plastic hollow board as packaging material, which is recyclable, environmentally friendly, waterproof and has good cushioning performance.

[0088] The packaging 200 for the pulsator washing machine provided in this embodiment of the utility model can have multiple implementations. Figures 1-14 This is a specific embodiment of the packaging 200 for a pulsator washing machine according to the present invention. In this embodiment, the packaging 200 is used to protect the pulsator washing machine 100. The packaging 200 for the pulsator washing machine in this embodiment can be adapted to accommodate other types of washing machines.

[0089] Figure 2 A schematic diagram of the structure of a package 200 for a pulsator washing machine is shown.

[0090] Reference Figure 1 , Figure 2 As shown, the package 200 of the pulsator washing machine includes a bottom cover 220. The bottom cover 220 is located at the bottom of the washing machine and is used to support the washing machine and protect the bottom of the washing machine.

[0091] The packaging 200 of the pulsator washing machine comprises a top cover 210. The top cover 210 and the bottom cover 220 are oppositely arranged along the direction from the top of the washing machine to the bottom of the washing machine. The top cover 210 is arranged at the top of the washing machine. The top cover 210 is used for protecting the top of the washing machine.

[0092] The packaging 200 of the pulsator washing machine comprises a corner guard 230. The corner guard 230 is connected between the top cover 210 and the bottom cover 220, and the corner guard 230 is connected at the corner opposite to the top cover 210 and the bottom cover 220. The top cover 210, the bottom cover 220 and the corner guard 230 form a containing area. The containing area is used for containing the pulsator washing machine 100.

[0093] The top cover 210, the bottom cover 220 and the corner guard 230 can be used to package the pulsator washing machine 100, and improve the convenience of transportation of the pulsator washing machine 100.

[0094] The corner guard 230 is in contact with two adjacent side surfaces of the washing machine arranged along the height direction of the washing machine, so as to protect the edges formed by the two adjacent side surfaces. One end of the corner guard 230 extending along the height direction of the washing machine is connected to the top cover 210, and the other end of the corner guard 230 extending along the height direction of the washing machine is connected to the bottom cover 220.

[0095] After the top cover 210, the corner guard 230 and the bottom cover 220 are assembled with the washing machine, they need to be arranged in a packaging box for transportation.

[0096] In actual application, the packaging box is usually designed as a cuboid structure for convenient transportation. Correspondingly, the top cover 210 and the bottom cover 220 are usually designed as a quadrilateral structure, so that the structure of the top cover 210, the bottom cover 220, the corner guard 230 and the washing machine after assembly is approximately a cuboid structure, so as to be arranged in the packaging box.

[0097] In some embodiments, the top cover 210, the bottom cover 220 and the corner guard 230 are all or at least one or two made of a plastic piece.

[0098] The plastic piece is made of at least one of polypropylene, polyethylene, polyvinyl chloride, polylactic acid, polybutylene adipate / terephthalate and polybutylene succinate.

[0099] The plastic piece has good cushioning performance without using foaming materials, has good protection effect, and can meet the protection of the pulsator washing machine 100.

[0100] The foaming material is a material made of plastic, rubber and the like as raw materials, and catalysts, foam stabilizers, foaming agents and the like as auxiliary materials, and generates bubbles in the plastic and rubber through physical foaming or cross-linking foaming, so that the plastic and rubber become porous substances, such as foamed plastic, foamed rubber, foamed resin and the like, and have the functions of cushioning, sound absorption, shock absorption, heat preservation and filtration.

[0101] The plastic part is not sensitive to humidity, has low water absorption, good waterproofness, and does not lose supportability after absorbing moisture.

[0102] The plastic part also has the advantages of anti-aging, light weight, and low cost.

[0103] In some embodiments, recycled plastic can also be added during the manufacturing process when manufacturing the plastic part. Recycled plastic is the reuse of plastic. After mechanical blades are used to crush the plastic, the plastic is formed into a raw material through forming processing, thereby completing the reuse of the plastic. The entire manufacturing and use process is low-carbon, environmentally friendly, and easy to recycle.

[0104] In some embodiments, the plastic part is a plastic hollow plate. The plastic hollow plate is a hollow plate made of plastic as the base material.

[0105] The above-mentioned plastic includes, but is not limited to, one or more of polypropylene (PP), polyethylene (PE), polyvinyl chloride (PVC), polylactide (PLA), polybutylene adipate / terephthalate (PBAT), and polybutylene succinate (PBS).

[0106] Polypropylene (PP) is a semi-crystalline thermoplastic with high impact resistance, strong and tough mechanical properties, and resistance to a variety of organic solvents and acid and alkali corrosion.

[0107] Polyethylene (PE) is a thermoplastic resin obtained by polymerization of ethylene. It is odorless, non-toxic, has excellent low-temperature resistance, good chemical stability, and can resist the corrosion of most acids and bases; it is insoluble in general solvents at room temperature, has low water absorption, and excellent electrical insulation.

[0108] Polyvinyl chloride (PVC) is a thermoplastic resin obtained by polymerization of vinyl chloride under the action of an initiator, and has good mechanical properties.

[0109] Polylactide (PLA) is a polymer obtained by polymerization of lactic acid as the main raw material. The raw material is abundant and can be regenerated. The production process is pollution-free, and the product can be biodegraded to achieve recycling in nature, so it is an ideal green polymer material. At the same time, polylactide has good thermal stability, good solvent resistance, and certain antibacterial, flame retardant, and ultraviolet resistance.

[0110] Polybutylene adipate / terephthalate (PBAT) is a petrochemical-based biodegradable plastic and is one of the degradable materials currently used in biodegradable plastic research. It can be biodegraded and composted, and can resist white pollution.

[0111] Polybutylene succinate (PBS) is synthesized by succinic acid and butanediol by condensation polymerization, the resin is milky white, no smell and taste, easy to be decomposed and metabolized by various microorganisms in nature or enzymes in the body of animals and plants, and finally decomposed into carbon dioxide and water, which is a typical completely biodegradable polymer material. It has good biocompatibility and bioabsorbability.

[0112] Therefore, the hollow plate made of the above-mentioned plastic as the base material not only can be recycled, green and environmental protection, but also has good buffering performance.

[0113] Among them, the formula of the above-mentioned plastic can be adjusted to meet the requirements of different types of household appliance packaging.

[0114] In some embodiments, additives are added to the above-mentioned plastic to meet the performance of different models of packaging.

[0115] The additives can include: reinforcing agents and toughening agents, the reinforcing agent is a material that can enhance the rigidity of the resin, and the toughening agent is a material that can enhance the toughness of the resin.

[0116] The reinforcing agent includes but is not limited to one or more of calcium carbonate, talc, mica, glass fiber, barium sulfate, magnesium sulfate whisker, and plant fiber.

[0117] Calcium carbonate is an inorganic compound with slight hygroscopicity.

[0118] The main component of talc is hydrous magnesium silicate, which has the excellent physical and chemical properties of lubricity, anti-stickiness, flow aid, fire resistance, acid resistance, insulation, high melting point, chemical inertness, good hiding power, softness, good gloss, and strong adsorption.

[0119] Mica is a rock-forming mineral that presents a hexagonal flaky crystal form, has very high insulation and good thermal conductivity, good chemical stability, and resistance to strong acid, strong base and pressure.

[0120] Glass fiber is a composite material synthesized by glass fiber material and high-heat-resistant material, which has high mechanical and dielectric properties, good heat resistance and moisture resistance, and good processability.

[0121] Barium sulfate has the advantages of narrow particle size distribution, good dispersion, strong chemical inertness, good stability, acid and alkali resistance, moderate hardness, high relative density, high whiteness, and absorption of harmful rays, and is a material with environmental protection function.

[0122] Magnesium sulfate whisker has excellent reinforcing effect on plastics. When used in polypropylene, it has better effect on improving the bending elastic modulus than glass fiber and talc, and increases the heat distortion temperature. It has the same reinforcing effect on phenolic resin as asbestos, and can improve the mechanical properties, electrical properties and flame retardancy of the product. It can also be used as a tackifier for coatings and the like.

[0123] The natural content of plant fiber environmentally friendly material can reach more than 80%, and the articles made thereof can be naturally degraded when discarded in the natural environment, which is a new type of green and environmentally friendly material. Plant fibers mainly play a mechanical support role in plant bodies. The above-mentioned reinforcing agent can be adjusted to meet the requirements of different types of household appliance packaging.

[0124] The toughening agent includes but is not limited to one or more of ethylene propylene diene rubber (EPDM), polyolefin elastomer (POE), thermoplastic elastomer (TPE), styrene-butadiene-styrene (SBS), and hydrogenated styrene-butadiene block copolymer (SEBS).

[0125] Ethylene propylene diene rubber (EPDM) is a terpolymer of ethylene, propylene and non-conjugated diene, which is resistant to polar solutions and chemicals, and has low water absorption.

[0126] Polyolefin elastomer (POE) is a high-performance polyolefin that is rubbery at room temperature, has small density, large bending, high low-temperature impact resistance, easy processing, and reusability.

[0127] Thermoplastic elastomer (TPE) is also known as artificial rubber or synthetic rubber, which has high elasticity, aging resistance, oil resistance, and other excellent properties, and also has the characteristics of easy processing and wide processing methods of ordinary plastics. It can be produced by injection molding, extrusion, blow molding and other processing methods, and the water gap corner powder can be directly reused 100% after crushing. It simplifies the processing process and reduces the processing cost. Therefore, thermoplastic elastomer has become the latest material to replace traditional rubber, which is environmentally friendly and non-toxic.

[0128] Styrene-butadiene-styrene (SBS) is a thermoplastic elastomer most similar to rubber, which can be processed by thermoplastic plastic processing equipment, has low energy consumption, simple process, short processing cycle, high production efficiency and low processing cost; the corner scrap can be recycled multiple times, saving resources and being beneficial to environmental protection.

[0129] Hydrogenated styrene-butadiene block copolymer (SEBS for short) is a saturated SBS, which has good temperature resistance, excellent aging resistance, excellent electrical properties, good solubility, blending properties and excellent oil filling property, and can be reused from offcuts, meeting environmental protection requirements. And the specific gravity is lighter. Among them, the formula of the above toughening agent can be adjusted to meet the requirements of different types of household appliance packaging.

[0130] In some embodiments, the above-mentioned plastic can be virgin material or recycled material. Virgin material refers to resin raw material that has not been used, and recycled material refers to water outlet material or post-consumer recycled material.

[0131] It should be noted that the plastic hollow plate can be a hollow plate with different internal structures made of plastic as the base material.

[0132] Among them, the plastic hollow plate can include: a honeycomb plate, and the honeycomb core of the honeycomb plate can include a "rice" type core and a "well" type core.

[0133] The plastic hollow plate can also include a "rice" type plate. That is, the internal structure of the plastic hollow plate is "rice" type, and the internal structure of the "rice" type serves as a reinforcing rib of the plastic hollow plate, which can enhance the strength of the plastic hollow plate.

[0134] The plastic hollow plate can also include a "well" type plate. That is, the internal structure of the plastic hollow plate is "well" type, and the internal structure of the "well" type serves as a reinforcing rib of the plastic hollow plate, which can enhance the strength of the plastic hollow plate.

[0135] In some embodiments, the above-mentioned plastic hollow plate is formed by extruding the base material, filler and auxiliary agent through a specific die after mixing them in an extruder.

[0136] It should be noted that the formula of the above-mentioned plastic part can be adjusted according to the weight of the specific impeller washing machine 100 to meet different types and weights of impeller washing machines 100.

[0137] In some embodiments, the thickness of the plastic hollow plate is 2mm-8mm. The thickness of the plastic hollow plate can also be 3mm, 5mm or any numerical range composed of two endpoints.

[0138] The plastic hollow plate with a thickness less than 2mm is thin and has low strength and insufficient toughness, which is easy to be damaged during transportation of the impeller washing machine 100. The plastic hollow plate with a thickness greater than 8mm is thick, which not only increases the cost of packaging, but also increases the weight of packaging, which is not convenient for transportation of the impeller washing machine 100.

[0139] The plastic hollow plate with a thickness of 2mm-8mm has sufficient strength and toughness to protect the pulsator washing machine 100, and the plastic hollow plate with a thickness of 2mm-8mm is light in weight, facilitating the transportation of the pulsator washing machine 100.

[0140] In some embodiments, the thickness of the plastic hollow plate is 3mm. At this time, the cost and weight of the plastic hollow plate constituting the packaging of the pulsator washing machine 100 are appropriate, and the strength and toughness of the plastic hollow plate meet the protection of the pulsator washing machine 100 during transportation.

[0141] In some embodiments, the thickness of the plastic hollow plate is 5mm. At this time, the strength and toughness of the plastic hollow plate meet the protection of the pulsator washing machine 100 during transportation. And at this time, the overall weight of the packaging of the pulsator washing machine 100 is appropriate, facilitating the transportation of the pulsator washing machine 100.

[0142] Referring to FIGS. 1-3, Figure 3 , Figure 4 In some embodiments, the top cover 210 includes a top cover body 211. The top cover body 211 can be formed by folding the top cover element, and the top cover body 211 is configured to be composed of at least a plastic piece.

[0143] The top cover body 211 includes a top top plate 2111 and a top surrounding barrier 2112. The top surrounding barrier 2112 surrounds the edge of the top top plate 2111 and is connected with the top top plate 2111.

[0144] The top top plate 2111 and the top surrounding barrier 2112 together define a first mounting cavity for accommodating the pulsator washing machine 100. The first mounting cavity is used to mount the top of the pulsator washing machine 100.

[0145] When the top cover 210 is wrapped around the top of the cabinet 10, the top top plate 2111 is in contact with the top surface of the cabinet 10, and the top surrounding barrier 2112 surrounds the side wall of the top of the pulsator washing machine 100. The top surrounding barrier is used to limit the position of the pulsator washing machine 100 on the top top plate 2111, reducing or avoiding the movement of the pulsator washing machine 100.

[0146] The top cover element is composed of the above-mentioned plastic piece. The top cover element can be folded through a preset folding track and form the top cover body 211.

[0147] In some embodiments, the top cover element is integrally formed from a plastic hollow plate. This simplifies the manufacturing process of the top cover 210 and improves the manufacturing efficiency.

[0148] The top cover body 211 is formed by folding the top cover components. The joints of each part are connected and fixed by ultrasonic welding, or by plugging or gluing. The components of the packaging 200 of the pulsator washing machine are assembled by simple splicing, which greatly improves the forming efficiency.

[0149] By using plastic for the top cover body 211, sufficient strength is ensured while achieving lightweight design, which helps reduce production costs and ease transportation burden. Furthermore, all materials used are recyclable and environmentally friendly, meeting functional requirements while adhering to sustainable development principles.

[0150] It is known that during the folding process to form the top cover body 211, the walls of the top enclosure include the outer side and the inner side.

[0151] In some embodiments, a cardboard structure may be added to the top cover 210 to further improve the overall strength of the top cover 210. When the cardboard structure is present and ultrasonic welding is not possible, it can be connected by interlocking or gluing.

[0152] Reference Figure 1 As shown, in this embodiment, the top and bottom of the pulsator washing machine 100 are opposite ends, the left and right sides of the pulsator washing machine 100 are opposite sides, and the front and rear sides of the pulsator washing machine 100 are opposite sides. In this embodiment, the top and bottom of the pulsator washing machine 100 represent the height direction (Z-axis direction) of the pulsator washing machine 100, the left to right side of the pulsator washing machine 100 represents the width direction (X-axis direction), and the front to rear side of the pulsator washing machine 100 represents the depth direction (Y-axis direction).

[0153] Reference Figure 3 As shown, in some embodiments, the top cover 210 further includes a first support component 212. The first support component 212 is disposed along the inner edge of the top cover body 211. The first support component 212 is connected to the top plate 2111.

[0154] By setting the first support component 212, the sides and top of the top cover body 211 are supported, so as to prevent the top cover body 211 from being deformed by external forces during transportation and improve the protection of the internal pulsator washing machine 100.

[0155] The side of the first support assembly 212 away from the top plate can contact the door cover 40 or the frame 12 to limit the pulsator washing machine 100 from the top.

[0156] In some embodiments, the first support assembly 212 is formed by folding a plate structure formed of a plastic piece. In order to simplify the process and improve the preparation efficiency.

[0157] Referring to Figure 3 , Figure 4 As shown in FIG. 1, the first support assembly 212 includes four support components. The four support components are arranged at the four corners of the top cover body 211. By arranging the support components at the four corners of the top cover body 211, when the top of the whole machine is subjected to force, the structure at the four corners can preferentially bear the force, thereby improving the anti-clamping property of the whole package.

[0158] In some embodiments, the first support assembly 212 and the top cover body 211 are connected by ultrasonic welding. In some possible implementations, the first support assembly 212 and the top cover body 211 are connected by pasting.

[0159] In some embodiments, the first support assembly 212 includes a first support component 2121 and a second support component 2122 arranged corresponding to the front side of the pulsator washing machine 100, and a third support component 2123 and a fourth support component 2124 arranged corresponding to the rear side of the pulsator washing machine 100.

[0160] Referring to Figure 9 As shown in FIG. 1, the bottom structure and height of the first support component 2121, the second support component 2122, the third support component 2123, and the fourth support component 2124 are matched with the shape of the frame 12 of the pulsator washing machine 100.

[0161] In some embodiments, the first support component 2121 and the second support component 2122 are symmetrically arranged, and the third support component 2123 and the fourth support component 2124 are symmetrically arranged. Since the top of the pulsator washing machine 100 is arranged to be inclined from the rear end to the front side, the height of the third support component 2123 is lower than the height of the first support component 2121, and the height of the fourth support component 2124 is lower than the height of the second support component 2122.

[0162] In some embodiments, referring to Figure 5 The first support assembly 212 includes a front support assembly arranged at the front side of the pulsator washing machine 100 and a rear support assembly arranged at the rear side of the pulsator washing machine 100. In some possible implementations, the first support component 2121 and the second support component 2122 are arranged as an integral structure, and the third support component 2123 and the fourth support component 2124 are arranged as an integral structure.

[0163] It can be known that in some embodiments, the first support component 2121 can be decomposed into a discontinuous multi-piece structure. Similarly, the second support component 2122 can be decomposed into a discontinuous multi-piece structure. The third support component 2123 can be decomposed into a discontinuous multi-piece structure. The fourth support component 2124 can be decomposed into a discontinuous multi-piece structure.

[0164] The skilled person in the art can set the structure of the first support assembly 212 according to the needs to adapt to the top structure of the impeller washing machine 100 of different models. By combining different first support assemblies 212, the packaging of the impeller washing machine 100 of different models can be achieved, greatly simplifying the manufacturing process of the packaging 200 and improving the manufacturing efficiency.

[0165] A protective lining is arranged on the surface of the bottom of the first support assembly 212 (away from the side of the top plate 2111), and there is a gap between the first support assembly 212 and the surrounding frame 12 or the door cover 40 of the impeller washing machine 100.

[0166] The size of the gap is in the range of 0-5mm. By setting the gap between 0-5mm, the door cover 40 or the surrounding frame 12 can press the protective lining by acting on the first support assembly 212. In this way, the shell 11 of the impeller washing machine 100 is stabilized, and the door cover 40 or the surrounding frame 12 is prevented from being scratched.

[0167] When the gap is greater than 5mm, the gap between the door cover 40 or the surrounding frame 12 and the first support assembly 212 is too large, causing the protective lining inside to move and causing scratching problems in some positions.

[0168] In some embodiments, referring to Figure 6 As shown in the figure, the top cover 210 further comprises a second support assembly 213, which is arranged in close contact with the top plate 2111, and the second support assembly 213 is arranged along the length direction of the top plate 2111.

[0169] In some embodiments, the material of the second support assembly 213 is solid wood or composite board. However, solid wood or composite board is prone to corrosion and mold under the condition of continuous high temperature and high humidity, which reduces the strength and attenuates the anti-clamping effect, thereby losing the protection effect on the whole machine.

[0170] In some embodiments, the material of the second support assembly 213 is set as fiber-reinforced thermosetting composite material. The material composition is 30%-50% unsaturated polyester / epoxy resin / phenolic resin and 50%-70% glass fiber / carbon fiber.

[0171] The unsaturated polyester / epoxy resin / phenolic resin in the material composition of the second support assembly 213 can be set to 35%, 40%, 45%, or a range composed of any two of the above values.

[0172] The glass fiber / carbon fiber in the material composition of the second support assembly 213 can be set to 55%, 60%, 65%, or a range composed of any two of the above values.

[0173] When the resin content is less than 30%, it can cause the inability to form a continuous phase matrix to wrap the reinforcing fiber due to insufficient fiber infiltration, or the resin-fiber cross-section shear strength can decrease, or the porosity can increase due to insufficient resin flow, thereby increasing the processing defect rate.

[0174] When the resin content is more than 50%, the material rigidity can be significantly reduced, the elastic performance can be deteriorated, and the cost can be increased.

[0175] When the fiber content is higher than 70%, the processing difficulty is multiplied, and the anisotropy is intensified. When the fiber content is less than 50%, it can cause the resin flow to be out of control.

[0176] In some possible embodiments, the material constituting the second support assembly 213 is a 35% unsaturated polyester and a 65% glass fiber composite material. The material composition of the second support assembly 213 can also be a range composed of any two values between the above endpoints.

[0177] In some embodiments, the second support assembly 213 is provided in a hollow square tube structure.

[0178] In some embodiments, the wall thickness of the second support assembly 213 is 1-3 mm. When the wall thickness of the second support assembly 213 is less than 1 mm, the wall thickness is too thin, and the support force provided is insufficient. When the wall thickness of the second support assembly 213 is greater than 3 mm, the wall thickness is too thick, which increases the weight of the entire package and is not conducive to transportation.

[0179] In some possible implementations, the wall thickness of the second support assembly 213 is set to 1 mm, 1.5 mm, 3 mm, or a range composed of any two of the above values.

[0180] It should be noted that the shape of the second support assembly 213 can be adjusted during the manufacturing process and can be set to a circular structure or a prismatic structure.

[0181] By combining 30-50% of unsaturated resin with 50-70% of glass fiber, the second support assembly 213 is formed by extrusion through a special die. By adjusting the content of glass fiber, the thickness of the wall of the second support assembly 213 adjusts its strength. The higher the glass fiber content, the thicker the wall, and the higher the strength.

[0182] In some possible implementations, the composition of the second support assembly 213 is 62% glass fiber, 20% unsaturated resin, 1% auxiliary agent, and 7% calcium carbonate.

[0183] By setting the first support assembly 212 and the second support assembly 213, the overall rigidity of the top cover 210 is improved, and the ability of the top cover 210 to resist external impact is also enhanced. In particular, the second support assembly 213 is arranged along the inside of the length direction of the top top plate 2111, which can effectively disperse the load and avoid damage caused by local overload.

[0184] In some embodiments, with reference to Figure 9 , the height of the first support assembly 212 is greater than the height of the second support assembly 213, so that the first support assembly 212 can lift the top top plate and reserve space for the second support assembly 213. Avoiding the second support assembly 213 from contacting the door cover 40 of the impeller washing machine 100.

[0185] In some embodiments, with reference to Figure 6 、 Figure 7 、 Figure 8 , the top cover enclosure includes a first top cover side 21125. The first top cover side 21125 is configured as an outer side arranged along one end of the width direction of the top top plate 2111.

[0186] In some embodiments, the top cover enclosure includes a second top cover side 21126. The second top cover side 21126 is configured as an outer side arranged along the other end of the width direction of the top top plate 2111.

[0187] The top cover enclosure includes a first top cover side edge 21121. The first top cover side edge 21121 is configured as an inner bottom edge corresponding to the first top cover side 21125. With reference to Figure 6 , the first top cover side edge 21121 is configured as a connecting edge between the inner side corresponding to the first top cover side 21125 and the top top plate 2111.

[0188] The top cover enclosure includes a second top cover side edge 21122. The second top cover side edge 21122 is configured as an inner bottom edge corresponding to the second top cover side 21126. With reference to Figure 6 , the second top cover side edge 21122 is configured as a connecting edge between the inner side corresponding to the second top cover side 21126 and the top top plate 2111.

[0189] With reference to Figure 7 、 Figure 8 , one end of the second support assembly 213 passes through the first top cover side edge 21121 without contacting the first top cover side 21125, and the other end of the second support assembly 213 passes through the second top cover side edge 21122 without contacting the second top cover side 21126.

[0190] One end of the second support assembly 213 passes through the corresponding inner side surface of the first top cover side surface 21125 without contacting the first top cover side surface 21125, and the other end of the second support assembly 213 passes through the corresponding inner side surface of the second top cover side surface 21126 without contacting the second top cover side surface 21126.

[0191] By the above arrangement, the length of the second support assembly 213 is slightly shorter than the length of the top top plate 2111 as a whole, so that when being squeezed, the outer packaging box and the top cover body 211 are first stressed, and after being compressed for a certain distance, the second support assembly 213 is stressed, and the anti-squeezing ability is stronger.

[0192] If the length of the second support assembly 213 is the same as or longer than the length of the top top plate 2111 as a whole, the second support assembly 213 is first stressed, and when a certain squeezing force is reached, the second support assembly 213 can be broken first, losing the anti-squeezing effect.

[0193] In some embodiments, the size of the cross-sectional side length of the second support assembly 213 is 15-40mm. The size of the cross-sectional side length of the second support assembly 213 is 15mm, 20mm, 30mm, 35mm, or a range of any two numerical combinations thereof.

[0194] In some embodiments, the cross-sectional side length of the second support assembly 213 is 20-30mm.

[0195] When the cross-sectional side length of the second support assembly 213 is less than 15mm, the second support assembly 213 is too thin, and its own strength is insufficient, resulting in low anti-squeezing performance of the top cover as a whole. When the cross-sectional side length of the second support assembly 213 is greater than 40mm, the second support assembly 213 is too thick, resulting in high production cost and increasing the weight of the top cover 210 itself, which is not convenient for transportation.

[0196] When the cross-sectional side length of the second support assembly 213 is between 15mm and 20mm, it is found that although the weight of the top cover 210 increases slightly, the second support assembly 213 can be damaged in some squeezing scenarios. Therefore, the cross-sectional side length of the second support assembly 213 is adjusted to be greater than 20mm.

[0197] When the cross-sectional side length of the second support assembly 213 is between 30mm and 40mm, it is found that although the strength is sufficient, the second support assembly 213 is too large to interfere with the door cover 40 of some models. Therefore, the cross-sectional side length of the second support assembly 213 is adjusted to be less than 30mm.

[0198] In some embodiments, the side (top surface) of the top top plate 2111 away from the bottom cover 220 is provided with a mounting portion (not shown in the figure). The mounting portion is configured to be recessed towards the direction of the bottom cover 220 relative to the top surface of the top top plate 2111. The second support assembly 213 is mounted in the mounting portion. The mounting portion is provided along the width direction of the top top plate 2111.

[0199] In some embodiments, the top cover 210 further comprises a fixing member 214. The fixing member 214 is mounted on the top surface of the top top plate 2111, and the fixing member 214 is used to mount the second support assembly 213 in the mounting portion.

[0200] In some embodiments, the fixing member 214 can be provided as a flat plate. The fixing member 214 is used to encapsulate the second support assembly 213 in the mounting portion.

[0201] In some embodiments, the fixing member 214 can also be provided as a U-shaped hollow plate. The center of the fixing member 214 forms a space for accommodating the second support assembly 213, and the two ends of the fixing member 214 are mounted on the top surface of the top top plate 2111.

[0202] By providing the fixing member 214, the fixing member 214 can enhance the integrity of the overall packaging of the impeller washing machine 100 when the impeller washing machine 100 falls or collides during transportation, so that the impeller washing machine 100 is not damaged.

[0203] In some embodiments, referring to Figure 3 , the second support assembly 213 is mounted on the side (bottom surface) of the top top plate 2111 facing the bottom cover 220.

[0204] One end of the second support assembly 213 is inserted into the corresponding inner side surface of the first top cover side surface 21125, and the other end of the second support assembly 213 is inserted into the corresponding inner side surface of the second top cover side surface 21126.

[0205] In some embodiments, the fixing member 214 can also be mounted on the bottom surface of the top top plate 2111, and is used to mount the second support assembly 213 on the bottom surface of the top top plate 2111.

[0206] In some embodiments, referring to Figure 4 , the fixing member 214 is provided as a U-shaped hollow plate. The center of the fixing member 214 forms a space for accommodating the second support assembly 213, and the two ends of the fixing member 214 are mounted on the bottom surface of the top top plate 2111.

[0207] In some embodiments, the top cover 210 further comprises a reinforcing rib provided inside the second support assembly 213. The reinforcing rib can effectively increase the anti-clamping performance of the second support assembly 213.

[0208] In some embodiments, referring toFigure 6 As shown, the top cover body 211 comprises a third top cover side 21123. The third top cover side 21123 corresponds to the front side of the top of the washing machine, and is used to connect one end of the first top cover side 21121 and one end of the second top cover side 21122.

[0209] The top cover body 211 comprises a fourth top cover side 21124, which corresponds to the rear side of the top of the washing machine. The fourth top cover side 21124 is arranged opposite to the third top cover side 21123, and is used to connect the other end of the first top cover side 21121 and the other end of the second top cover side 21122.

[0210] In some embodiments, the second support assembly 213 can be provided as one. In some embodiments, the second support assembly 213 is provided as two. The number of the second support assembly 213 can be adjusted by those skilled in the art according to the needs.

[0211] Referring to Figure 6 As shown, the distance between the edge along the length direction of the second support assembly 213 and the third top cover side 21123 is H, wherein H is greater than 240 mm. When H is less than 240 mm, the second support assembly 213 does not work when the package box is clamped from the rear side.

[0212] In some embodiments, the distance between the edge along the length direction of the second support assembly 213 and the third top cover side 21123 is H, wherein H is less than 350 mm. When H is greater than 350 mm, uneven stress is prone to occur when the whole is clamped.

[0213] The distance between the edge along the length direction of the second support assembly 213 and the third top cover side 21123 can be 250 mm, 280 mm, 300 mm, 330 mm, or a range formed by any two of the above values.

[0214] In some embodiments, the top cover 210 further comprises a protective layer arranged on the inner side wall of the top cover body 211. The inner side wall of the top cover body 211 is configured to be in contact with the top side of the cabinet 10. In some possible implementations, the inner side wall of the top cover 2112 is configured to be in contact with the surrounding frame 12 of the impeller washing machine 100.

[0215] In some embodiments, the protective layer comprises non-woven fabric or velvet. Both non-woven fabric and velvet are flexible barriers. By arranging non-woven fabric or velvet between the inner side wall of the top cover body 211 and the top side of the cabinet 10, the top side of the cabinet 10 can be protected, and scratches on the top surface of the impeller washing machine 100 can be avoided.

[0216] The embodiment of the present application also provides a drum washing machine assembly, which comprises the drum washing machine 100 and the improved packaging 200 of the drum washing machine.

[0217] In some embodiments, referring to Fig. 1, the drum washing machine 100 comprises a top cover 210, a bottom cover 220, a drum 230, a washing machine body 240 and a washing machine door 250. Figure 10 As shown in Fig. 2, the bottom cover 220 comprises a bottom cover body 221. The bottom cover body 221 is at least formed by folding an avoiding fold plate 2211, which is configured to be composed of a plastic piece.

[0218] In some embodiments, referring to Fig. 1, the drum washing machine 100 comprises a top cover 210, a bottom cover 220, a drum 230, a washing machine body 240 and a washing machine door 250. Figure 14 As shown in Fig. 2, the bottom cover body 221 can also comprise 2-6 layers of laminated plastic hollow plates. The bottom cover 220 composed of 2-6 layers of plastic hollow plates has optimal buffering performance and can meet the protection requirements of the drum washing machine 100.

[0219] Meanwhile, the bottom cover 220 composed of 2-6 layers of plastic hollow plates is light in weight and low in cost, facilitating the transportation of the drum washing machine.

[0220] In some embodiments, the bottom cover 220 can comprise 3 layers of laminated plastic hollow plates, which can be completely suitable for the packaging of the drum washing machine 100.

[0221] In some embodiments, the inner part of the plastic hollow plate adopts a rib type or a paperboard edge type, so as to enhance the strength of the plastic hollow plate.

[0222] In some embodiments, the bottom cover body 221 is composed of a full plastic hollow plate. In some possible implementation manners, the bottom cover body 221 can be composed of a full plastic hollow plate and a paperboard.

[0223] In the above embodiment, the adhesion mode is generally adopted between the multiple layers of plates. In some implementation manners, the ultrasonic welding mode can be adopted to combine the two layers of hollow plates.

[0224] The avoiding fold plate 2211 is folded to form a partial structure of the bottom cover body 221. The connection between the structure and other parts is connected and fixed by using the ultrasonic welding mode, and can also be connected by using the insertion mode or the pasting mode. The components of the packaging 200 of the drum washing machine are assembled by using the simple splicing mode, so that the forming efficiency is greatly improved.

[0225] By using the plastic piece material for the bottom cover body 221, the sufficient strength is ensured and the light weight is realized, which is helpful to reduce the production cost and the transportation burden. In addition, the materials used are all recyclable and environmentally friendly materials, which meet the functional requirements and take into account the sustainable development concept.

[0226] In some embodiments, referring to Fig. 1, the drum washing machine 100 comprises a top cover 210, a bottom cover 220, a drum 230, a washing machine body 240 and a washing machine door 250. Figure 11The bottom cover body 221 includes a support bottom plate 22101 and a bottom cover sidewall 22102. The bottom cover sidewall 22102 is arranged around the support bottom plate 22101, and the support bottom plate 22101 and the bottom cover sidewall 22102 jointly define a second mounting cavity.

[0227] The bottom of the pulsator washing machine 100 is arranged in the second mounting cavity, the support bottom plate 22101 is used to support the pulsator washing machine 100, and the bottom cover sidewall 22102 is used to limit the placement position of the pulsator washing machine 100 on the support bottom plate 22101, so as to prevent the pulsator washing machine 100 from shaking on the support bottom plate 22101.

[0228] In some embodiments, referring to FIG. 2, the bottom cover body 221 includes a first bottom side 221021 and a second bottom side 221022 arranged along the width direction, and a third bottom side 221023 and a fourth bottom side 221024 arranged along the depth direction. Figure 12

[0229] The first bottom side 221021 is in contact with the right side of the pulsator washing machine 100, and the second bottom side 221022 is in contact with the left side of the pulsator washing machine 100. The third bottom side 221023 is in contact with the front side of the pulsator washing machine 100, and the fourth bottom side 221024 is in contact with the back side of the pulsator washing machine 100.

[0230] In some embodiments, referring to FIG. 2, the bottom cover body 221 includes a first avoiding structure 22111 arranged on the inner sidewall of the bottom cover sidewall 22102. Figure 14

[0231] In some embodiments, referring to FIG. 2, the bottom cover sidewall 22102 includes at least one first avoiding structure 22111. The first avoiding structure 22111 is arranged on the inner sidewall of the bottom cover sidewall 22102. The arrangement position of the first avoiding structure is adapted to the first accommodating part of the back of the pulsator washing machine 100. Figure 11

[0232] The avoiding flap 2211 is foldable along a preset folding line. When the avoiding flap 2211 is folded, at least part of the area of the first avoiding groove 22112 forms the first avoiding structure 22111 after folding.

[0233] The avoiding flap 2211 is arranged as a flat and even hollow structure. Two grooves are cut at the corresponding positions of the avoiding flap 2211, and the hollow overhanging part is bent backward to form the first avoiding structure 22111.

[0234] By adopting the cold working process of cutting and bending, a complex mold is not needed, the process can be simplified, the production efficiency of the bottom cover 220 is improved, and the material is saved.​​​

[0235] It is known that the first clearance structure 22111 can be flexibly adapted by adjusting the length and bending angle of the first clearance groove 22112. Moreover, due to the lightweight (density 0.6-1.2g / cm³) and high bending strength (bending modulus ≥800MPa) characteristics of the hollow board, it can still maintain structural stability after the groove is cut.

[0236] In practical use, a rodent-proof plate needs to be installed on the bottom of the pulsator washing machine 100. To facilitate the installation of the rodent-proof plate, corresponding guide ribs are provided on the bottom of the pulsator washing machine 100. These guide ribs protrude from the bottom plane of the pulsator washing machine 100.

[0237] In some embodiments, refer to Figure 11 As shown, the supporting base plate 22101 also includes a second clearance structure 22122. The second clearance structure 22122 extends inward from the top surface of the supporting base plate and cooperates with the guide rib at the bottom of the pulsator washing machine 100.

[0238] Reference Figure 14 As shown, the second clearance structure 22122 is configured as a groove-shaped structure. The second clearance structure 22122 can be formed by stacking multiple hollow plastic plates, which are defined as support plates 2212.

[0239] A second clearance groove 22121 is provided at a corresponding position on the support plate 2212 that makes up the bottom cover body 221. After multiple support plates 2212 are stacked and installed, the second clearance grooves 22121 overlap to form a second clearance structure 22122. Second clearance structures 22122 of different sizes can be formed by opening second clearance grooves 22121 at different positions in different support plates 2212.

[0240] In some embodiments, a plurality of second avoidance structures 22122 are provided, and the plurality of second avoidance structures 22122 are spaced apart.

[0241] In some embodiments, a plurality of second avoidance structures 22122 may be connected to form an overall avoidance structure.

[0242] The base of the 100 top-loading washing machine has a stepped structure with a step height ranging from 0 to 25 mm.

[0243] To match the stepped structure described above, refer to Figure 10 As shown, in some embodiments, the bottom cover 220 further includes a stepped structure 222. The stepped structure 222 is disposed on the bottom cover body 221. The stepped structure 222 cooperates with the second receiving portion of the pulsator washing machine 100.

[0244] The step structure 222 can limit the cabinet 10, effectively fix the cabinet 10, and avoid or reduce the left-right or front-back movement of the cabinet 10.

[0245] In some embodiments, referring to Figure 13 The step structure 222 is formed by a plurality of inserts 2221.

[0246] Referring to Figure 12 The second avoiding structure 22122 is arranged along the depth direction of the support bottom plate 22101 to adapt to the guide ribs at the bottom of the pulsator washing machine 100 and enhance the transportation stability of the pulsator washing machine 100.

[0247] In some embodiments, the second avoiding structure 22122 is arranged between the step structure 222 and a bottom cover surface of the bottom cover side wall 22102. The distance between the edge of the bottom side surface and the bottom cover surface of the second avoiding structure 22122 is H1, where H1 ranges from 30 mm to 80 mm.

[0248] Referring to Figure 12 The distance between the edge of the first bottom side surface 221021 and the first bottom side surface 221021 of the second avoiding structure 22122 is H1, where H1 ranges from 30 mm to 80 mm.

[0249] H1 can be set to 30 mm, 40 mm, 50 mm, 60 mm, 70 mm, 80 mm, or a range formed by any two of the values.

[0250] When H1 is less than 30 mm, the first bottom side surface 221021 or the second bottom side surface 221022 is too close, which reduces the strength of the entire support plate 2212. When H1 is greater than 80 mm, the size of the entire bottom cover body 221 is too large, which is not conducive to the transportation of the entire pulsator washing machine 100.

[0251] In some embodiments, the distance between the edge of the bottom side surface and the bottom cover surface of the second avoiding structure 22122 is H2, where H2 ranges from 60 mm to 120 mm.

[0252] H2 can be set to 60 mm, 70 mm, 80 mm, 90 mm, 100 mm, 110 mm, 120 mm, or a range formed by any two of the values.

[0253] Referring to Figure 12 The distance between the edge of the first bottom side surface 221021 and the first bottom side surface 221021 of the second avoiding structure 22122 is H2, where H2 ranges from 60 mm to 120 mm.

[0254] When H2 is less than 60mm, the distance between the entire second avoiding structure 22122 and the first bottom side 221021 or the second bottom side 221022 is too small, which is not conducive to the strength of the entire support plate 2212.

[0255] When H2 is greater than 120mm, the size of the entire bottom cover body 221 is too large, which is not conducive to the transportation of the entire impeller washing machine 100.

[0256] In some embodiments, the distance between the second avoiding structure 22122 away from the edge of the second bottom side 221022 and the second bottom side 221022 ranges from 60-120mm. The distance between the second avoiding structure 22122 close to the edge of the second bottom side 221022 and the second bottom side 221022 ranges from 30-80mm. The position of the second avoiding structure 22122 is reasonably set to adapt to the setting position of the guide ribs on the bottom of the impeller washing machine 100.

[0257] In some embodiments, the bottom cover 220 further comprises a mounting through hole 2213 formed on the support bottom plate 22101, and the mounting through hole 2213 is used to accommodate the support leg of the impeller washing machine 100. Referring to Figure 10 , the mounting through hole 2213 is mounted on the support bottom plate 22101 and cooperates with the four support legs of the impeller washing machine 100. By mounting the four support legs in the mounting through hole 2213, the position of the impeller washing machine 100 in the packaging 200 can be defined, and the position is limited to prevent the problem of insufficient protection due to misalignment of the internal structure of the impeller washing machine 100 and the packaging 200.

[0258] In some embodiments, the bottom cover 220 further comprises a bottom corner. The bottom corner is arranged at the bottom of the bottom cover body 221. In some possible implementations, the bottom corner is arranged at the four corners of the bottom cover body 221.

[0259] The above improvement scheme solves the problems of high cost, low environmental protection, and poor adaptability in the related art by material replacement (EPS→hollow plate) and process innovation (mold forming→cold processing bending), and achieves comprehensive improvement of economy, sustainability, and production efficiency on the premise of ensuring functionality.
