Technical Field

[0001] The present invention belongs to the technical field of packaging, and particularly relates to a packing box assembly and a laundry treatment device. Background Art

[0002] In order to prevent the washing machine from being bumped and damaged during transportation and transfer, it is usually packed in a packing box when leaving the factory. The existing packing box is usually of an integral structure, including four upper swing lids and four lower swing lids at the bottom. During the packing process, the four lower swing lids at the bottom are first fixed, such as by tape, and after the washing machine is placed in the packing box, the four upper swing lids of the packing box are fixed, and then horizontal and vertical packing straps are respectively arranged on the outer side of the packing box for reinforcement.

[0003] However, the overall strength of such a packing box is uniform. During the transfer process, such as clamping and transferring, since the bottom and the side plates of the box body bear greater pressure, it is extremely easy to cause damage to the bottom and the box body of the packing box. In addition, after the user receives the washing machine, the tape on the upper part needs to be removed to take out the washing machine, which is likely to damage the upper part of the packing box.

[0004] Correspondingly, there is a need in the art for a new packing box assembly to solve the above problems. Summary of the Invention

[0026] The preferred implementation manners of the present invention will be described below with reference to the accompanying drawings. Those skilled in the art should understand that these implementation manners are only used to explain the technical principles of the present invention and are not intended to limit the protection scope of the present invention. For example, although this embodiment is described by taking a washing machine as an example, it can also be applied to other types of clothing treatment devices such as a dryer, a washer-dryer, or a mother-and-child machine.

[0027] It should be noted that in the description of the present invention, the terms "center",

[0028] "upper", "lower", "left", "right", "vertical", "horizontal", "inner",

[0029] "outer", etc., indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings.

In addition, the terms "first", "second", "third" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance.

[0030] Refer to Figure 1 and Figure 2 , Figure 1 is a schematic structural view of the packing box assembly of a washing machine according to an embodiment of the present invention, Figure 2 is an exploded schematic view of the packing box assembly of a washing machine according to an embodiment of the present invention. As shown in Figure 1 and Figure 2 shown and referring to Figure 1In the orientation shown, the packaging box assembly of the washing machine includes a separately provided top cover 1 and a packaging box. A strapping band 3 is provided on the outer sides of the top cover 1 and the packaging box 2 to fix the top cover and the packaging box together. When disassembling the package, it is only necessary to separate the top cover from the packaging box. Among them, the top cover 1 includes a base body 11 and a protruding part 12, and the packaging box 2 includes a box body 21 and an upper cover assembly 22 located above the box body. The upper cover assembly 22 includes a front swing cover 221, a rear swing cover 222, and two side swing covers 223.

[0031] It can be seen that the box body 21 is arranged as a cube with a cross-section approximately in a rectangular structure, and the base body 11 is arranged as a rectangular structure adapted to its size. In the assembled state, the top cover 1 is arranged above the box body 21 and covers the outer sides of the front swing cover 221 and the rear swing cover 222 to form a bending area. The two side swing covers 223 are attached to the upper surface of the top cover 1, and then the two side swing covers are fixedly connected by means of an adhesive tape, such as the adhesive tape 4, so as to be able to firmly fix the top cover above the box body and achieve the fixed connection of the packaging box assembly, increasing the strength of the upper part of the packaging box assembly. It can be understood that the two side swing covers can also be arranged below the top cover and above the washing machine, so that the two side swing covers can be fixed without the aid of an adhesive tape. Those skilled in the art can make adjustments to the above settings according to needs to adapt to specific application scenarios.

[0032] Referring to Figure 1 、 Figure 2 and Figure 3 , Figure 3 is a schematic diagram of the unfolded structure of the top cover of an embodiment of the present invention. As shown in 1, Figure 2 and Figure 3 shown and referring to Figure 2 the orientation shown, the top cover 1 includes a middle base body 11 and protruding parts 12 arranged on both sides of the base body and extending outward. The protruding parts 12 form a bending area, and the front swing cover 221 and the rear swing cover 222 respectively extend into the bending areas on the corresponding sides to connect with the top cover, thereby increasing the strength of the upper part of the packaging box assembly. Taking the protruding part on the left side of the top cover in Figure 3 as an example, the protruding part 12 includes a first part 121, a second part 122, a third part 123, and a fourth part 124 arranged in sequence from right to left. The bending areas formed by folding the first part 121, the second part 122, the third part 123, and the fourth part 124 can wrap the front swing cover / rear swing cover to achieve the fixed connection of the top cover and the packaging box. Looking from left to right, the second part 122 is folded downward relative to the first part 121 to form the first right-angle bend on the left side, the third part 123 is folded to the right relative to the second part 122 to form the second right-angle bend directly below the first right-angle bend, and the fourth part 124 is folded upward relative to the third part 123 to form the third right-angle bend on the same horizontal plane as the second right-angle bend.

[0033] In this way, three right-angle bends form an accommodating space, and the front swing cover / rear swing cover can just be arranged in this accommodating space. That is to say, the bending areas formed by folding the first part, the second part, the third part and the fourth part can cover the outside of the front swing cover / rear swing cover.

[0034] It can be understood that the first part and the base body can be fixedly connected or integrally formed, and the length of the first part can be the same as or different from that of the base body. It can be understood that the width of the fourth part is less than or equal to the width of the second part. In this way, during the formation of the bending area, the fourth part can be bent upward and clamped between the front swing cover / rear swing cover and the box body to form a stable bending area. It can be understood that the width of the third part should not be too large or too small, and it is appropriate to be slightly larger than the thickness of the front swing cover / rear swing cover. In this way, the front swing cover / rear swing cover can be firmly covered in the accommodating space.

[0035] In order to better fix the top cover 1 and the packing box 2 together, a packing belt 3 can be arranged on the outer sides of the top cover 1 and the packing box 2. By means of the bundling of this packing belt, the top cover and the packing box can be connected more firmly, thereby increasing the strength of the upper part of the packing box assembly. In this way, during the hoisting and transportation process, hoisting can be realized by arranging the hoisting structure in the bending area, and there is no need to worry about the damage of the bending area.

[0036] In order to ensure that the packing belt has sufficient tensile force during the hoisting process, for example, a steel packing belt with higher strength is selected as the material of the packing belt. It can be understood that the packing belt can also be made of materials such as plastic-steel belts with higher tensile strength. Those skilled in the art can adjust the material of the packing belt according to needs to adapt to specific application scenarios.

[0037] In order to realize the reliable bundling of the packing belt 3, a bundling area 4 is arranged on the second part, and the packing belt 3 is arranged in this bundling area 4 to bundle the second part 122 and the packing box 2 together in the horizontal direction. In order to better fix the packing belt in the bundling area, at least one limiting structure is arranged in the bundling area. For example, opening grooves 1221 serving as limiting structures are respectively arranged at both ends of the second part corresponding to the bundling area. In this way, it is possible to better fix the top cover and the packing box together without arranging a vertical packing belt, further increasing the strength of the upper part of the packing box assembly, and thus being able to better realize the packaging of the washing machine. In the assembled state, the packing belt 3 bundles the top cover and the packing box through the four opening grooves 1221 arranged at the four corners, thereby avoiding problems such as the box body slipping caused by the displacement of the packing belt in the vertical direction during the hoisting process.

[0038] It can be understood that the limiting structure can also be a structure formed by the second part indenting inward at a position corresponding to the bundling area, or a corrugated structure can be provided at a position corresponding to the bundling area. Those skilled in the art can adjust the setting method of the limiting structure according to needs to adapt to specific application scenarios. It can be understood that the number of limiting structures can be determined according to the actual situation. If the weight of the object to be packaged is small, fewer limiting structures can be provided; if the weight of the object to be packaged is large, more limiting structures can be provided.

[0039] Referring to Figure 1 、 Figure 2 、 Figure 3 and Figure 4 , Figure 4 is a schematic structural diagram when the box body of the packaging box assembly of a washing machine according to an embodiment of the present invention is unfolded. As Figure 1 、 Figure 2 、 Figure 3 and Figure 4 shown and referring to Figure 4 shown in the orientation, the packaging box 2 includes a box body 21, an upper cover assembly 22 above the box body, and a lower cover assembly 23 below the box body, so as to better package the washing machine. Among them, the box body 21 is a cuboid structure formed by folding two opposite side plates 211 arranged in sequence. The lower cover assembly 23 includes two pairs of lower swing covers 231 arranged on the four side edges of the rectangular structure. The two pairs of lower swing covers 231 are connected by overlapping each other to form a rectangular bottom adapted to the size of the box body to bear the weight of the washing machine.

[0040] For example, an adhesive area can be provided at the overlapping part of the two pairs of lower swing covers, and an adhesive is used in the adhesive area to better bear the weight of the washing machine. For example, the adhesive is white latex. Through such a setting, the strength of the bottom of the packaging box is increased, and thus the overall strength of the packaging box assembly is further increased.

[0041] It can be understood that a reinforcing plate can also be provided above the two pairs of lower swing covers to better achieve the packaging of the washing machine. In this way, after the washing machine is loaded into the packaging box, during the hoisting and transportation process, the weight of the washing machine is jointly borne by the reinforcing plate and the lower cover assembly, greatly reducing the load-bearing of the lower cover assembly and improving the service life of the packaging box.

[0042] Continuing to refer to Figure 3 and Figure 4 ,as Figure 3 and Figure 4As shown, each part of the packing box 2 and the top cover 1 is made of corrugated cardboard 6. Due to the special structure of the corrugated cardboard itself (the inside of the corrugated cardboard is a corrugated structure), the packing box assembly has good buffering performance. In this way, the washing machine installed in the packing box assembly can be better protected during transportation. In the assembled state, the direction of the corrugated paper of the corrugated cardboard 6 is perpendicular to the folding direction of the corrugated cardboard. In this way, during the hoisting and transportation process, the force-bearing direction of the packing box assembly is perpendicular to the direction of the corrugated paper, enabling the packing box assembly to withstand greater external forces, not easily deformed, and better protecting the washing machine installed in the packing box assembly.

[0043] In summary, in the preferred technical solution of the present invention, by covering the bending area formed by the protruding parts of the top cover arranged on both sides of the base on the outer sides of the front swing cover and the rear swing cover, the connection between the top cover and the packing box is realized, and the strength of the upper part of the packing box is increased. Among them, the protruding part includes a first part, a second part, a third part, and a fourth part arranged in sequence from right to left. The bending area is formed by folding these four parts to cover the front swing cover / rear swing cover, and the two side swing covers are arranged on the outer side of the base and fixed by adhesive tape, thereby realizing the fixed connection between the top cover and the packing box. In addition, opening grooves are respectively arranged at both ends of the second part. In this way, by arranging the packing straps at the opening grooves at the four corners, the top cover and the packing box can be better tied together in the horizontal direction without additionally arranging vertical packing straps. In addition, by arranging an adhesive area or adding a reinforcing plate at the overlapping part where the four swing covers of the lower cover assembly overlap each other, the strength of the bottom of the packing box is enhanced. Through such a setting, the overall strength of the packing box assembly is increased. In this way, the washing machine can be better protected. And when hoisting and transportation are required, the hoisting structure is fixed between the bending area on the front side or the rear side and the box body, and hoisting and transportation can be realized. When unpacking, the washing machine can be taken out only by separating the top cover from the packing box without damaging the packing box assembly.

[0044] So far, the technical solution of the present invention has been described in combination with the preferred embodiments shown in the drawings. However, it is easy for those skilled in the art to understand that the protection scope of the present invention is obviously not limited to these specific embodiments. Without departing from the principle of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will fall within the protection scope of the present invention.
