[0043] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0044] The specific technical features described in the specific embodiments may be combined in any suitable manner, unless they are inconsistent. For example, different embodiments and technical solutions may be formed by combining different specific technical features. To avoid unnecessary repetition, the various possible combinations of the specific technical features in the present invention will not be described separately.

[0045] In the following description, the terms "first, second, ..." are used solely to distinguish different objects and do not imply any similarity or connection between the objects. It should be understood that the directions "above," "below," "outside," and "inside" refer to normal use. The terms "front," "back," "left," and "right" refer to the front, back, left, and right sides of the laundry treatment device when it is normally placed. The front side is the side of the laundry treatment device facing the user.

[0046] It should be noted that the terms "comprises," "includes," or any other variations thereof are intended to encompass non-exclusive inclusion, such that a process, method, article, or apparatus comprising a list of elements includes not only those elements but also other elements not explicitly listed, or elements inherent to such process, method, article, or apparatus. In the absence of further limitations, an element defined by the phrase "comprising a ..." does not preclude the presence of additional identical elements in the process, method, article, or apparatus comprising that element. "A plurality" means greater than or equal to two.

[0047] Currently, most washing machine packaging solutions, with the exception of corrugated cardboard boxes, use polystyrene (EPS) foam for top, side, and bottom padding. EPS is lightweight, offers excellent cushioning, is moisture-resistant, and easy to shape. However, its high strength makes it prone to continuous cracking under heavy loads, and it is flammable. Its low density makes it difficult to recycle and can easily contribute to white pollution. With increasing demand for environmentally friendly materials, EPS foam will be gradually banned and phased out.

[0048] During transportation, the inner padding of the packaging plays an important role in support, positioning, and cushioning protection. The present application proposes a packaging top pad and packaging bottom pad structure that is environmentally friendly, easy to recycle, and can easily maintain good and stable cushioning performance during transportation conditions to replace conventional foam materials. It consists of a plastic recycled blister base, a support structure made of blow-molded plastic or paper material, and corner supports made of recyclable rubber such as TPV. The performance of the packaging bottom pad depends on the overall stiffness of the blister base, the vertical cushioning support of the support structure, and the cushioning recoverability of the corner supports. This packaging can provide better protection for washing machine products.

[0049] The embodiments of the present application provide a packaging base mat and a packaging device. The packaging device can be configured as a clothing processing device, which can be a drum-type clothing processing device. The clothing processing devices described in the embodiments of the present application include washing machines, dryers, and the like. Washing machines include single-wash washing machines with a separate washing function, washing machines with washing and dehydrating functions, and washing-drying machines with washing and drying functions. The packaging base mat of the embodiments of the present application can be used as a base mat for clothing processing devices and placed on the bottom of the clothing processing device when it is in normal use.

[0050] A drum washing machine primarily consists of several parts, including the casing, motor, drum, and control panel. The casing is the exterior of the drum washing machine, protecting the internal mechanical and electronic components. It's typically made of metal or plastic and has an opening on the front through which users can load and unload clothing. The drum is the core component of a drum washing machine. It's a cylindrical container that holds clothing and water and is typically made of stainless steel or plastic. The motor is the power source of the drum washing machine, driving the drum's rotation and controlling its speed and direction. The motor is typically mounted on the rear side of the drum and connected to it via belts or gears. The control panel is the user interface for the drum washing machine, through which users select wash programs. The control panel is typically located on the top of the casing and has buttons.

[0051] Drum washing machines typically have a base at the bottom. This base is a device designed to mount and move the washing machine, typically made of metal or plastic. The base's primary function is to elevate the machine for easier operation and protect it from moisture, dust, and friction from the floor. It also provides greater stability and reduces vibration and noise during the wash cycle. The base typically consists of four feet, each with an adjustable screw mechanism to adjust the height of the machine to your needs. By adjusting these screws, users can adjust the stability of the machine based on its height and the flatness of the floor.

[0052] As shown in Figures 1 and 4, an embodiment of the present application provides a packaging base mat 10, which is configured to package the bottom of a clothing processing device 6. The packaging base mat 10 includes a bottom plate 1 and a support structure 2. The bottom plate 1 includes a base plate 11 and a surrounding edge 12. The surrounding edge 12 is arranged around the edge of the base plate 11 and protrudes from the base plate 11. The surrounding edge 12 and the base plate 11 enclose a cavity 13, one end of the cavity 13 is open, and the other end is the surface of the base plate 11. The bottom plate 1 packages the bottom of the clothing processing device, and its size should be made according to the bottom surface of the clothing processing device to ensure that the bottom plate 1 can cover the entire surface or substantially the entire surface of the bottom of the clothing processing device.

[0053] As shown in Figures 1 and 4, the base plate 11 is flat, and the skirt 12 is continuously provided around the edge of the base plate 11. The skirt 12 protrudes from the base plate 11. It should be noted that the skirt 12 not only protrudes from the edge of the base plate 11 in height, but also protrudes from the edge of the base plate 11 in the plane extending direction of the base plate 11. Therefore, the skirt 12 has a certain width. During installation, the clothing treatment device is placed on the skirt 12, and its bottom surface is clear of the surface of the base plate 11. The base plate 11 is placed close to the rigid floor and easily contacts it. The top of the skirt 12 is at a certain distance from the rigid floor. Therefore, if the package accidentally falls onto the rigid floor, the bottom surface of the clothing treatment device is clear of the surface of the base plate 11, that is, at a certain distance from the rigid floor, so it is not easily directly impacted by the rigid floor. The skirt 12 forms a protective enclosure for the bottom shell of the clothing treatment device, preventing dust and other debris from entering. The skirt 12 also cooperates with the outer packaging box to facilitate overall packaging.

[0054] As shown in Figures 1 and 4 , the support structure 2 can cushion the internal structure. For example, the support structure 2 can deform to provide cushioning. The support structure 2 is disposed on the base plate 11 and protrudes beyond the cavity 13, forming small protrusions scattered across the bottom plate 1. Multiple support structures 2 are provided, and by aligning with the internal components of the laundry treatment device and their deformable nature, they provide sufficient cushioning force to mitigate external vibrations. For example, the support structure 2 can be configured to support structures such as the motor and drum, thereby cushioning these structures and reducing the load transmitted from the washing machine's internal structure to the outer shell. The bottom plate 1 is integrally molded using blister plastic, eliminating the need for bonding or other processes to connect different structures, thereby improving bottom plate processing efficiency. Blistering is a plastic processing technique that heats and softens a flat, rigid plastic sheet, then vacuum-adsorbs it onto a mold surface and cools it into shape. It is widely used in industries such as plastic packaging. Blister packaging saves raw materials, is lightweight, easy to transport, and offers excellent sealing properties, meeting environmentally friendly and green packaging requirements. The base plate 1 can be made of recycled plastic and serves as the substrate for the entire packaging base 10, maintaining the overall rigidity of the packaging base 10 and preventing it from warping or bending. For example, the base plate 1 can be made of PET blister material. PET blister material is hard, tough, strong, and environmentally friendly and non-toxic, meeting the high strength and environmental requirements of the base plate 1.

[0055] In the embodiments of the present application, the base plate, including the base plate and the surrounding edge, is integrally molded from a single piece of plastic. This allows the bottom surface of the packaging clothing handling device to be configured from a single piece of material. This reduces the number of production steps required to form the base plate, significantly reducing material loss and labor input, and improving production efficiency. The base plate is made of plastic to increase rigidity, providing stable support for the bottom of the clothing handling device. The support structure provides cushioning for the internal structure, resulting in a packaging base pad with both high strength and strong cushioning capacity, meeting the requirements of supporting the clothing handling device and buffering against external vibrations.

[0056] In some embodiments, as shown in Figures 1 and 4, the material of the support structure 2 includes at least one of the following: blow-molded plastic or paper. Blow-molded plastic is manufactured using a blow molding process. Blow molding involves injecting a melted plastic preform into a split mold. After the mold is closed, compressed air is immediately injected to inflate the plastic preform and force it to adhere to the inner wall of the mold. After cooling, the blow-molded plastic is completed. Paper is easy to process and handle and can be made into products of various shapes and sizes through cutting, folding, and gluing. Furthermore, paper is made from natural plant cellulose, making it highly biodegradable and relatively low in environmental pollution. For example, the support structure 2 can be made of materials such as honeycomb cardboard. Honeycomb cardboard is manufactured based on the principles of natural honeycomb structures. It is a novel, environmentally friendly, energy-saving sandwich material made by gluing corrugated paper into countless hollow, three-dimensional regular hexagons to form a single, load-bearing member—a paper core. Facing paper is then bonded to both sides of the core. Honeycomb cardboard is made of a flexible paper core and facial paper, offering excellent toughness and resilience. Its unique honeycomb sandwich structure provides excellent cushioning properties.

[0057] The support structure of the embodiment of the present application is made of at least one of the following materials: blow-molded plastic or paper. Both blow-molded plastic and paper have good resilience, resulting in a support structure with excellent cushioning properties, providing sufficient cushioning force to mitigate external vibrations. Furthermore, both blow-molded products and paper are environmentally friendly, contain no harmful substances, and are easily recyclable.

[0058] In some embodiments, as shown in Figures 2 and 5, the support structure 2 is detachably connected to the base plate 1. The support structure 2 and base plate 1 are manufactured separately and then assembled together to form the packaging base mat 10. For clothing processing devices of different sizes, the length and width are different, so the size of the packaging base mat 10 used is also different. Generally, when the sizes of clothing processing devices of the same type are different, the packaging base mat 10 required is only the size of the base plate 1, while the size and dimensions of the support structure 2 are basically the same. Therefore, the base plate 1 can be manufactured to a matching size, and base plates 1 of different sizes can all be adapted to the same size support structure 2. Therefore, during processing, only one set of molds for making the support structure 2 and molds for base plates 1 of different sizes need to be prepared. Assuming that the packaging base mat 10 is manufactured as a whole, it is necessary to design multiple sets of molds of different sizes according to the different sizes of clothing processing devices. This reduces the space and number of molds occupied by the molding molds to a certain extent, reducing mold costs.

[0059] For example, the bottom plate 1 is provided with a protrusion / groove upward, and the corresponding support structure 2 is provided with a groove / protrusion downward, and the protrusion is engaged with the groove to detachably connect the bottom plate 1 and the support structure 2. Alternatively, the bottom plate 1 and the support structure 2 are connected by bonding.

[0060] The supporting structure of the embodiment of the present application is detachably connected to the base plate, so that by replacing base plates of different sizes, a packaging base pad suitable for washing machines of different models can be formed, thereby improving the versatility of parts between products of different sizes; and the separation of the base plate and the supporting structure is more suitable for stacking storage than the entire packaging base pad, which greatly reduces the storage space required for the same number of parts; and the materials used for the base plate and the supporting structure are different, and their separate processing and manufacturing conforms to the actual processing and production process, which is beneficial to the efficiency of actual production.

[0061] In some embodiments, as shown in Figures 2 and 3, one end of the substrate 11 that closes the cavity 13 protrudes toward the opening of the cavity 13 to form a protrusion 14, and the protrusion 14 has a first groove 15. The first groove 15 is formed by the protrusion 14 being axially recessed in a direction away from the opening of the cavity 13. The support structure 2 needs to be inserted from the opening of the first groove 15 to the bottom of the first groove 15. The support structure 2 and the first groove 15 have an interference fit. After the support structure 2 is installed in the first groove 15, the support structure 2 can be bonded to the substrate 11 to achieve further connection.

[0062] The support structure of the embodiment of the present application is installed in the first groove, so that the protrusion limits the radial and circumferential movement of the support structure, so that it can only be pulled out in the direction of the opening of the first groove. In addition, the interference fit between the support structure and the first groove, and the adhesion of the support structure to the substrate make it difficult for the support structure to be pulled out in the direction of the opening of the first groove, so that the support structure can be stably installed in the first groove.

[0063] In some embodiments, as shown in Figures 5 and 6, one end of the substrate 11 that closes the cavity 13 protrudes toward the opening of the cavity 13 to form a protrusion 14. The protrusion 14 is axially penetrated to form a through hole 16 that communicates with the cavity 13. The support structure 2 extends through the through hole 16 from the side of the substrate 11 away from the cavity 13 and is detachably connected to the substrate 11. The support structure 2 can have an interference fit with the through hole 16.

[0064] The support structure of the embodiment of the present application passes through the through hole, so that the protrusion limits the radial and circumferential movement of the support structure, so that it can only be pulled out along the extension direction of the through hole. In addition, the support structure can be interference fit with the through hole, so that the support structure is not easily pulled out along the extension direction of the through hole, so that the support structure can be stably installed in the through hole and detachably connected to the substrate.

[0065] In some embodiments, as shown in Figures 2 and 5, the side wall of the support structure 2 is protruding with a snap 21, and the side wall of the protrusion 14 is correspondingly provided with a snap slot 22, or the side wall of the support structure 2 is provided with a snap slot 22, and the side wall of the protrusion 14 is correspondingly provided with a snap 21; wherein, when the support structure 2 is connected to the substrate 11 in place, the snap 21 is snapped into the snap slot 22.

[0066] The support structure and the substrate of the embodiment of the present application are further connected by snapping. After the snap is snapped into the snap-in socket, the support structure and the substrate are not easy to move along the extension direction of the through hole, so that the support structure can be further stably installed in the through hole.

[0067] In some embodiments, as shown in Figures 1 and 4 , corner supports 3 are secured to the base plate 11 at the intersection of its edges. The corner supports 3 are secured to the base plate 1 by slots and glued to the base plate 1, or the perimeter 12 is secured to the perimeter 12 at the intersection of its edges. The corner supports 3 and perimeter 12 are structurally coordinated. The base of the laundry processing device includes four feet 62 positioned at the corners of the base. Four corner supports 3 are provided. These four corner supports 3 can be configured to support the four feet 62 of the laundry processing device. Each foot 62 can be inserted into a corresponding corner support 3 for position retention, thereby better maintaining the balance of the laundry processing device. The corner supports 3 are elastic, effectively cushioning impact forces on the feet. The elastic modulus of the corner supports ranges from 2 to 20 MPa. The center of the base is hollowed out, allowing the support structure 2 to pass through the base and extend into the interior of the laundry processing device to support the components of the laundry processing device located within the outer shell. The four feet of the clothing processing device are inserted into the four corner supports 3, and a certain buffer gap is maintained between the bottom surface of the feet and the bottom plate 1 to avoid high-speed impact on the rigid bottom surface during transportation.

[0068] The corner support members of the embodiment of the present application can provide support and protection for the base of the clothing processing device. The inventors of the present application have found in practice that when the product is being transported or accidentally dropped, the risk of impact at the base of the clothing processing device is greater than that at other positions. The provision of corner support members can effectively cushion the impact force on the base, thereby providing targeted protection for the parts of the clothing processing device that are prone to impact, which is conducive to improving the effectiveness of the packaging bottom pad in protecting the clothing processing device.

[0069] In some embodiments, as shown in Figures 1 and 4 , the corner supports 3 are made of rubber. For example, TPV (thermoplastic vulcanizate) and other materials are used. Rubber has a certain elasticity, so the corner supports 3 can act as a buffer, reducing the impact of impact on the base of the clothing treatment device. Rubber is recyclable, which minimizes waste emissions and protects the ecological environment. Rubber also has good processing properties, allowing the corner supports 3 to be processed into various shapes according to actual usage. The processing process is also simple, making it easy to form the corner supports 3 in the appropriate shape according to the base.

[0070] The material of the corner support member in the embodiment of the present application includes rubber, which is not only easy to process, but also the rubber is recyclable, which is beneficial to environmental protection.

[0071] In some embodiments, as shown in Figures 1 and 4, the peripheral edge portion 12 defines a positioning hole 4, which is located outside the corner support 3. When the packaging base mat 10 is assembled with another structure, the other structure can be inserted into the positioning hole 4 for fixation, thereby achieving assembly of the packaging base mat with the other structure.

[0072] The positioning holes are provided on the surrounding edge portion of the embodiment of the present application, so that the assembly and fixation of the packaging base pad and other structures are more convenient, which can improve the packaging efficiency during actual production.

[0073] [Corrected 18.10.2024 according to Rule 91] As shown in Figure 7, an embodiment of the present application further provides a packaging device configured to package a clothing processing device 6, and the packaging device includes a packaging box, a packaging bottom pad 10, a packaging top pad 5 and a packaging side pad. The packaging box has a storage space inside to accommodate the clothing processing device 6. For example, the packaging box can be a corrugated cardboard box, or a cardboard box made by combining corrugated cardboard and honeycomb cardboard. As shown in Figures 10, 11a, 11b and 11c, the packaging bottom pad 10 is located in the storage space and below the clothing processing device 6. The bottom plate 1 is configured to support the outer shell 64 of the clothing processing device 6, and the multiple support structures 2 are configured to support the components of the clothing processing device 6 located inside the outer shell 64, such as the motor 61, the cylinder 63 and other components. The support structure 2 fits in place with the internal motor 61 and the cylinder 63, and the supporting force should be greater than 4000N.

[0074] As shown in Figures 8 and 9, the top packing pad 5 is configured to protect the top surface of the clothing processing device 6; the side packing pads are configured to protect the sides of the clothing processing device 6. The side packing pads are located between the top packing pad 5 and the bottom packing pad 10 and can be inserted into the top packing pad 5 and the bottom packing pad 10 for positioning. The bottom packing pad 10, the side packing pads, and the top packing pad 5 serve as inner pads, directly contacting the clothing processing device 6. The packaging box serves as the outer packaging and directly bears the impact of external forces. The two are used together to provide a double layer of protection for the clothing processing device 6.

[0075] The packaging device of the embodiment of the present application includes a packaging top pad, a packaging side pad and a packaging bottom pad, so as to provide comprehensive protection for the clothing processing device; the packaging side pads are located between the packaging top pad and the packaging bottom pad and can be inserted into the packaging top pad and the packaging bottom pad, so that the packaging side pads, the packaging top pad and the packaging bottom pad can form a whole after the clothing processing device is packaged, and jointly withstand and share the impact of external forces, and also facilitate the installation of the packaging side pads. After they are installed, they can be fixed to the packaging top pad and the packaging bottom pad without the assistance of external force.

[0076] In some embodiments, as shown in Figures 8 and 9, the packaging top pad 5 includes a top plate 51 and a protective member 52 disposed around the edge of the top plate 51. The top plate 51 wraps around the top of the laundry processing device, and the edge of the top plate 51 has an L-shaped cross-section. The protective member 52 also has an L-shaped cross-section, overlapping the edge of the top plate 51 to provide protection. The protective member 52 includes a first sub-protective member 521 extending in a first direction and a second sub-protective member 522 extending in a second direction. The first and second directions are directions L1 and L2, respectively, as shown in Figure 7. The first and second sub-protective members 521 and 522 abut against each other to wrap around the edge of the top plate 51. The first and second sub-protective members 521 and 522 act as a reinforcement, acting as a crossbeam, with their lengths being greater than or equal to the extension length of the top plate 51 in the first and second directions, respectively. The top plate 51 is integrally molded from blister plastic. It can be made from recycled plastic. As the base of the entire packaging top pad 5, the top plate 51 should maintain its overall rigidity.

[0077] The cross-section of the protective member in the embodiment of the present application is L-shaped, and the protective member overlaps the edge of the top plate to form protection, so that the protective member can cover the outermost edge of the top plate inside so that it is not exposed, thereby strengthening the packaging strength at the edge of the top plate and increasing the stacking strength.

[0078] In some embodiments, as shown in Figures 8 and 9, the protective member 52 is made of blow-molded plastic or paper. The protective member 52 is made of a material with high lateral compressive strength. Lateral compressive strength refers to the ability of a paperboard to withstand pressure applied parallel to the side of the paperboard. Flat compressive strength refers to the ability of a paperboard to withstand deformation caused by pressure applied perpendicular to the paperboard at a single point.

[0079] For example, paper corner protectors are suitable for paper materials. They are made by gluing two layers of kraft paper with multiple layers of tube paper in between, wrapping, extruding, shaping, and cutting. The two ends are smooth, burr-free, and perpendicular to each other. They are a 100% recyclable alternative to wood and offer high strength and rigidity. Their high lateral compressive strength allows them to effectively withstand clamping pressure when their ends are compressed. Their high compressive strength makes them an ideal alternative to wood packaging or other bulky packaging methods. Their lightweight, durable design and environmentally friendly nature make them a popular green packaging material. Paper corner protectors use water-soluble adhesives, making them easily recyclable and environmentally friendly.

[0080] As shown in Figures 8 and 9 , during actual packaging, the first sub-protective members 521 are located on the front and rear sides of the product, extending in the left-right direction. The second sub-protective members 522 are located on the left and right sides of the product, extending in the front-back direction. The extension length of the first sub-protective members 521 in the first direction is greater than or equal to the extension length of the top plate 51 in the first direction, resulting in the first sub-protective members 521 partially extending beyond the edge of the top plate 51 extending in the first direction. Therefore, during the clamping process, the product is typically clamped from side to side, and the first part to come into contact with the clamp is the first sub-protective members 521 extending in the left-right direction. The strength of the first sub-protective members 521 is greater than that of the top plate 51, thus effectively protecting the product inside and resisting the clamping force. The first sub-protective members 521, in conjunction with the top plate 51, should provide a lateral support force greater than 2000N.

[0081] As shown in Figures 8 and 9, the cross-section of the protective member 52 is L-shaped. Part of the protective member 52 overlaps the top of the top plate 51 near the edge, and part of it overlaps the side of the top plate 51 near the edge. When the top of the package is subjected to force, the part of the protective member 52 overlapping the top of the top plate 51 near the edge is the force-bearing surface of the package top pad 5 at the top. The first sub-protective member 521 and the second sub-protective member 522 are in contact with each other, which can increase the force-bearing area of ​​the package top pad at the top, thereby dispersing the pressure in the plane of the entire top plate 51, reducing the problem of damage to the package top pad.

[0082] In the embodiment of the present application, the first sub-protection member located in the front-to-back direction plays a lateral supporting role during the transportation and clamping process, and the second sub-protection member located in the left-to-right direction plays a buffering role in pushing and oblique impact conditions. At the same time, the protective member plays a buffering and supporting role in the top and bottom directions.

[0083] In all kinds of transportation conditions, the packaging bottom pad of the whole machine packaging structure bears the largest load and is also crucial to the protection of the product. The packaging bottom pad structure composed of replacing the original polystyrene foam material (EPS) with a blister base, a support structure of blow-molded plastic or paper material, and corner supports made of recyclable rubber not only increases the diversity of the packaging structure, but also facilitates environmentally friendly and low-carbon recycling. The support structure 2 and the corner supports 3 serve as the main load-bearing supports of the packaging bottom pad 10. The support structure 2 supports the internal structure such as the drum and motor, and the four corner supports 3 directly support the four bottom feet, avoiding large deformation of the bottom of the washing machine during transportation conditions, which may cause problems such as installation balance or debugging. The load-bearing and cushioning performance of the packaging bottom pad is attributed to the overall stiffness of the base, the vertical cushioning support of the support structure, and the cushioning recoverability of the corner supports.

[0084] The above description is merely a preferred embodiment of the present application and does not limit the scope of protection of the present application.
