[0008] Hereinafter, embodiments of a washing machine and the like according to the present disclosure will be described with reference to the drawings. The present disclosure is not limited to the contents described in the following embodiments, and appropriate design changes can be made within the scope of the configuration of the present disclosure. In the drawings, identical or equivalent elements are given the same reference numerals, and redundant explanations will be omitted. Below, the main parts and parts related to the present disclosure will be mainly described.

[0009] In the present disclosure, the term "washing machine" refers to a general device that performs various processes, such as washing, on laundry. Examples of processes for laundry include washing, drying, deodorizing, and sterilizing. The laundry is not particularly limited. Examples of laundry include cloth products. Specific examples of laundry include clothing such as clothes, hats, and gloves; personal belongings such as shoes, bags, handkerchiefs, and towels; curtains; bedding such as blankets, towel blankets, and futon covers; carpets; stuffed toys; and the like.

[0010] The term "vertical washing machine" refers to a washing machine in which, when installed, the rotation axis of the tub extends substantially vertically.

[0011] In this specification, the terms front, rear, left, right, top and bottom correspond to the front, rear, left, right, top and bottom, respectively, when viewed from the washing machine toward the user.

[0012] Fig. 1 is a perspective view that schematically shows the appearance of a washing machine 1 packaged in a package 2. Fig. 2 is a perspective view that schematically shows the appearance of the washing machine 1. Fig. 3 is a cross-sectional view that schematically shows the internal structure of the washing machine 1.

[0013] As shown in FIG. 1, packaging body 2 is a member for packaging washing machine 1. Washing machine 1 is a vertical washing machine. Washing machine 1 is an example of an object to be packaged in this embodiment. Note that the object to be packaged is not limited to washing machine 1, and may be any object that can be packaged.

[0014] 2 and 3, the washing machine 1 will be described. The washing machine 1 has a substantially rectangular prism shape. The washing machine 1 includes a housing 10, a lid 12, and a washing tub 13.

[0015] The housing 10 is made of, for example, metal or synthetic resin, and has a substantially rectangular shape in a plan view. The housing 10 has a laundry inlet 11X on an upper surface 11. Specifically, the housing 10 has a bottomed tubular shape with an opening as the laundry inlet 11X provided at one end (upper portion) of the tubular body. Examples of the bottomed tubular shape include a bottomed cylindrical shape and a bottomed rectangular tubular shape.

[0016] The top surface 11 of the housing 10 has a pair of first ends 11A extending in the front-to-rear direction and a pair of second ends 11B extending in the left-to-right direction. The pair of first ends 11A consists of a left end 11A1 located on the left side of the top surface 11 of the housing 10 and a right end 11A2 located on the right side. The pair of second ends 11B consists of a front end 11B1 located on the front side of the top surface of the housing 10 and a rear end 11B2 located on the rear side.

[0017] The top surface 11 of the housing 10 has first corners 11C located on the front end 12B side of the lid 12. Specifically, the top surface 11 of the housing 10 has a pair of first corners 11C at the front.

[0018] The pair of first corners 11C are located at the intersections of the pair of first end portions 11A and the front end portion 11B1. The pair of first corners 11C include a left front corner 11C1 located at the intersection of the left end portion 11A1 and the front end portion 11B1, and a right front corner 11C2 located at the intersection of the right end portion 11A2 and the front end portion 11B1.

[0019] The top surface 11 of the housing 10 has second corners 11D located on the pivot support side of the lid 12 (i.e., on the rear end 12C side of the lid 12). Specifically, the top surface 11 of the housing 10 has a pair of second corners 11D at the rear of the top surface 11.

[0020] The pair of second corners 11D are located at the intersections of the pair of first end portions 11A and the rear end portion 11B2. The pair of second corners 11D consist of a left rear corner 11D1 located at the intersection of the left end portion 11A1 and the rear end portion 11B2, and a right rear corner 11D2 located at the intersection of the right end portion 11A2 and the rear end portion 11B2.

[0021] Lid 12 is disposed above housing 10, and rear end 12C is pivotally supported so as to be openable and closable from front end 12B. In plan view, laundry inlet 11X is provided inside lid 12. Lid 12 opens and closes laundry inlet 11X. With lid 12 open, laundry is introduced into washing tub 13 through laundry inlet 11X. Lid 12 is maintained openable and closable by, for example, a hinge. Specifically, lid 12 is provided on rear portion 11E of top surface 11 of housing 10. Rear end 12C of lid 12 is rotatably attached to rear portion 11E of top surface 11 of housing 10. Front end 12B of lid 12 rotates vertically around rear end 12C of lid 12.

[0022] The lid 12 has a pair of side edges 12A extending in the front-to-rear direction. The side edges 12A consist of a left edge 12A1 located on the left side of the lid 12 and a right edge 12A2 located on the right side.

[0023] The lid 12 has a front end 12B extending in the left-right direction at the front of the lid 12, and a rear end 12C extending in the left-right direction at the rear of the lid 12. When the lid 12 is closed, the front end 12B of the lid 12 is located on a first corner 11C of the top surface 11 of the housing 10.

[0024] As shown in FIG. 3, washing machine 1 includes, inside housing 10, washing tub 13 for accommodating contents such as laundry, outer tub 14 disposed outside washing tub 13, and the like.

[0025] The washing tub 13 is also referred to as an inner tub, and is disposed inside the outer tub 14. The washing tub 13 and the outer tub 14 each have a bottomed cylindrical shape with one end (preferably the upper part) of the cylindrical body being open. Examples of the bottomed cylindrical shape include a bottomed cylindrical shape and a bottomed rectangular cylindrical shape. The washing tub 13 and the outer tub 14 each have a bottom opening in the approximate center of the bottom. The bottom opening penetrates the lower part of the washing tub 13 and the outer tub 14, and can function as a drainage part for discharging water from the washing tub 13 and the outer tub 14.

[0026] Washing tub 13 may be a washing tub (also referred to as a tub with holes) in which holes are provided on the side wall (circumferential surface) of washing tub 13 to allow water to flow in and out between washing tub 13 and outer tub 14. Washing tub 13 may also be a washing tub (also referred to as a tub without holes) in which holes are not provided on the side wall of washing tub 13 to allow water to flow in and out between washing tub 13 and outer tub 14. Figure 3 shows an example where washing tub 13 is a tub without holes.

[0027] Fig. 4 is a perspective view that simply shows the appearance of the washing machine 1 with the cushioning material 300 and the bottom part 400 installed, viewed from the front left. Fig. 5 is a perspective view that simply shows the appearance of the washing machine 1 with the cushioning material 300 and the bottom part 400 installed, viewed from the top left. Fig. 6 is a cross-sectional schematic view in the up-down, front-rear direction of the washing machine 1 with the cushioning material 300 and the bottom part 400 installed. Fig. 7 is a perspective view that simply shows the appearance of the washing machine 1 with the cushioning material 300 placed thereon. Fig. 8 is a perspective view that simply shows the appearance of the cushioning material 300. The packaging body 2 will be described with reference to Figs. 4 to 8.

[0028] Packaging body 2 includes cushioning materials 300. Specifically, packaging body 2 includes a pair of cushioning materials 300 placed above washing machine 1, a bottom portion 400 on which washing machine 1 is placed, a storage section 100 that stores washing machine 1, and a lid portion 200 that functions as an upper lid for storage section 100.

[0029] The storage section 100 stores the washing machine 1. The lid section 200 functions as an upper lid for the storage section 100. Each of the pair of cushioning materials 300 absorbs external forces applied to the washing machine 1. Each of the pair of cushioning materials 300 is installed between the storage section 100 and the washing machine 1. In detail, when the washing machine 1 is stored in the storage section 100, each of the pair of cushioning materials 300 is installed between the storage section 100 and the washing machine 1. Each of the pair of cushioning materials 300 can pack the upper part of the housing 10 and the lid 12 of the washing machine 1. The washing machine 1 is installed in the bottom section 400. The bottom section 400 functions as the bottom of the storage section 100.

[0030] The pair of cushioning materials 300, the first cushioning material 300A and the second cushioning material 300B, are disposed on the left and right sides of the washing machine 1, respectively.

[0031] Specifically, the first buffer material 300A includes a first buffer section 310 arranged to cover the left front corner 11C1, which is the first corner 11C; a second buffer section 320 arranged continuously upward from the first buffer section 310; a third buffer section 330 arranged to cover the left rear corner 11D1, which is the second corner 11D of the top surface 11 of the housing 10 located on the pivot support side of the lid 12; a fourth buffer section 340 connecting the second buffer section 320 and the third buffer section 330; and a fifth buffer section 350 arranged continuously rearward from the first buffer section 310.

[0032] The second buffer material 300B includes a first buffer section 310 arranged to cover the right front corner 11C2, which is the first corner 11C; a second buffer section 320 arranged continuously upward from the first buffer section 310; a third buffer section 330 arranged to cover the right rear corner 11D2, which is the second corner 11D of the top surface 11 of the housing 10 located on the pivot support side of the lid 12; a fourth buffer section 340 connecting the second buffer section 320 and the third buffer section 330; and a fifth buffer section 350 arranged continuously rearward from the first buffer section 310.

[0033] The pair of cushioning materials 300 have the same structure. The following description focuses on one of the pair of cushioning materials 300.

[0034] Cushioning material 300 is placed above washing machine 1 and packs the upper part of housing 10 and lid 12. Cushioning material 300 is made of, for example, polystyrene foam.

[0035] As shown in Figures 6 to 8, the cushioning material 300 includes a first cushioning section 310 arranged to cover a first corner 11C of the upper surface 11 of the housing 10 located at the front end 12B of the lid 12, a second cushioning section 320 arranged continuously upward from the first cushioning section 310, a third cushioning section 330 arranged to cover a second corner 11D of the upper surface 11 of the housing 10 located at the pivot support side of the lid 12, a fourth cushioning section 340 connecting the second cushioning section 320 and the third cushioning section 330, and a fifth cushioning section 350 arranged continuously rearward from the first cushioning section 310, and the lid 12 can be fixed between the fourth cushioning section 340 and the fifth cushioning section 350 when the lid 12 is open.

[0036] With this configuration, when stress (impact) is applied from above to washing machine 1 in which lid 12 is disposed between fourth buffering section 340 and fifth buffering section 350 and is fixed with lid 12 open by buffering material 300, the stress is transmitted continuously to second buffering section 320, first buffering section 310 of buffering material 300, and first corner portion 11C of housing 10, thereby preventing the stress from being transmitted to lid 12. First corner portion 11C of housing 10 has a higher strength than lid 12, and therefore, when stress is applied from above to washing machine 1 packaged using buffering material 300, the load on washing machine 1 can be reduced.

[0037] Furthermore, buffer material 300 can secure washing machine 1 with lid 12 open, thereby preventing moisture from accumulating inside washing tub 13. As a result, even if washing machine 1 is temporarily placed in a humid environment during transportation or storage and moisture enters washing tub 13, the moisture can be quickly discharged, preventing mold from growing in washing tub 13.

[0038] Fig. 9 is a perspective view showing the outline of a washing machine on which a conventional cushioning material is placed. As shown in Fig. 9, conventional cushioning material 300R is placed on washing machine 1 with lid 12 of washing machine 1 closed. Because lid 12 is located on first corner 11C of top surface 11 of housing 10, when stress is applied from above, there is a possibility that the stress will be transmitted to lid 12 via cushioning material 300R.

[0039] Therefore, when the washing machine 1 is packed using the conventional cushioning material 300R, the cushioning material 300R is placed above the washing machine 1, a bottom portion (described later) is placed below the washing machine 1, and further, a support portion 500R extending along the up-down direction of the washing machine 1 is placed between the cushioning material 300R and the bottom portion. By adopting such an embodiment, stress applied to the cushioning material 300R is transmitted to the bottom portion via the support portion 500R and dispersed, thereby reducing the stress transmitted to the lid 12.

[0040] On the other hand, in the present embodiment, when stress is applied from above to washing machine 1 fixed with lid 12 open by cushioning material 300, the stress is transmitted continuously to second cushioning portion 320, first cushioning portion 310 of cushioning material 300, and first corner portion 11C of housing 10, thereby preventing the stress from being transmitted to lid 12. As a result, there is no need to provide support portion 500R for dispersing stress as in the prior art, and the entire package 2 can be made compact.

[0041] The cushioning material 300 is a member having an internal space, and changes shape when stress is applied. The cushioning material 300 has a shape extending along the front-rear direction of the washing machine 1.

[0042] Cushioning material 300 is placed above washing machine 1 so that a gap is provided between lid 12 and housing 10 when lid 12 is open. Cushioning material 300 can secure lid 12 so that the gap between housing 10 and lid 12 is connected to washing tub 13. For example, by inserting side end 12A of lid 12 between fourth buffer portion 340 and fifth buffer portion 350 of cushioning material 300 and bringing first buffer portion 310 into contact with first corner portion 11C of top surface 11 of housing 10, cushioning material 300 can secure washing machine 1 with lid 12 open.

[0043] The first buffer portion 310 is provided so as to cover a first corner portion 11C of the upper surface 11 of the housing 10 located on the front end portion 12B side of the lid 12. Specifically, the rear surface 310D of the first buffer portion 310 is in contact with the first corner portion 11C and covers the first corner portion 11C.

[0044] The first buffering portion 310 may have an upper surface 310B in contact with the lid 12 when the lid 12 is open.

[0045] Second buffer section 320 is provided continuously upward from first buffer section 310. With this configuration, when stress is applied from above to washing machine 1 fixed with lid 12 open by buffer material 300, the stress is transmitted continuously to second buffer section 320 of buffer material 300, first buffer section 310, and first corner section 11C of housing 10, thereby preventing the stress from being transmitted to lid 12. As a result, when stress is applied to washing machine 1 from above, the load on washing machine 1 can be reduced.

[0046] In a cross-sectional view in the up-down, front-rear direction, the second buffer section 320 is directly connected to the first buffer section 310. The length of the second buffer section 320 in the front-rear direction is, for example, approximately constant.

[0047] In a plan view from above, at least a portion of second buffering section 320 overlaps first buffering section 310. In a plan view from above, second buffering section 320 preferably overlaps entirely with first buffering section 310. By adopting such an embodiment, when stress is applied from above to washing machine 1 fixed with lid 12 open by buffer material 300, shear stress is applied to the connection between first buffering section 310 and second buffering section 320, which can prevent damage and other such events, and the load on washing machine 1 can be further reduced.

[0048] The rear surface 320D of the second buffer section 320 is located forward of the rear surface 310D that covers the first corner 11C of the first buffer section 310, the front surface 320C of the second buffer section 320 is arranged on the same plane as the front surface 310C of the first buffer section 310, and the first buffer section 310 is arranged in the front-to-rear direction from the front surface 320C of the second buffer section 320 to above the first corner 11C.

[0049] This configuration is particularly effective for use with washing machines 1 in which the closed position of lid 12 is tilted downward toward the front. When lid 12 is tilted downward toward the front, front end 12B of lid 12 may be located forward of front end 11B1 of top surface 11 of housing 10 when lid 12 is opened nearly horizontally. For example, when lid 12 is tilted downward toward the front in the closed position, front end 12B moves forward as lid 12 opens to a horizontal position, and may be located forward of front end 11B1 of top surface 11 of housing 10. When lid 12 is packed in this position, rear surface 320D of second buffer portion 320 covering front end 12B of lid 12 is located forward of first corner 11C.

[0050] In this embodiment, first buffering portion 310 is formed in the front-rear direction from front surface 320C of second buffering portion 320 to above first corner 11C, so that when an impact is applied to second buffering portion 320 in the vertical direction, as shown by the arrow in Fig. 8, the impact can be dissipated to first corner 11C via first buffering portion 310, thereby preventing damage to second buffering portion 320. As a result, the impact can be prevented from being transmitted to lid 12, and the load on washing machine 1 can be reduced.

[0051] The third buffering portion 330 is provided so as to cover a second corner portion 11D of the upper surface of the housing 10 located on the pivot support side (rear end portion 12C side) of the lid 12. Specifically, a front surface 330C of the third buffering portion 330 contacts the second corner portion 11D and covers the second corner portion 11D.

[0052] The third buffering portion 330 extends upward from the second corner portion 11D. The length of the third buffering portion 330 in the front-rear direction is, for example, approximately constant.

[0053] The fourth buffering section 340 connects the second buffering section 320 and the third buffering section 330. The fourth buffering section 340 extends in the front-to-rear direction and connects an upper portion 320U of the second buffering section 320 and an upper portion 330U of the third buffering section 330. The fourth buffering section 340 is located at the top of the buffer material 300.

[0054] The first buffer section 310, the second buffer section 320, the third buffer section 330, and the fourth buffer section 340 have the same length in the left-right direction. Here, the fact that the first buffer section 310, the second buffer section 320, the third buffer section 330, and the fourth buffer section 340 have the same length in the left-right direction means that the length in the left-right direction of the first buffer section 310, the second buffer section 320, the third buffer section 330, and the fourth buffer section 340 is within a range of 90% or more and 110% or less of the average length in the left-right direction of the first buffer section 310, the second buffer section 320, the third buffer section 330, and the fourth buffer section 340, respectively.

[0055] It is preferable that the center portion of fourth buffering section 340 in the front-to-rear direction does not contact lid 12. By adopting such an embodiment, a gap is provided between lid 12 and fourth buffering section 340, so that when stress is applied from above to washing machine 1 fixed with lid 12 in the open state by buffering material 300, the stress can be effectively prevented from being transmitted to lid 12. The center portion of fourth buffering section 340 in the front-to-rear direction refers to a region that includes the midpoint of fourth buffering section 340 in the front-to-rear direction and is between ¼ and ¾ of the length of fourth buffering section 340 in the front-to-rear direction.

[0056] The fifth buffering section 350 is provided continuously in the rear direction from the first buffering section 310. The fifth buffering section 350 is connected to the upper and lower ends of the first buffering section 310, and is provided extending from the front to the rear direction.

[0057] When lid 12 is open, fifth buffering section 350 has upper surface 350B in contact with lid 12 and lower surface 350A in contact with upper surface 11 of housing 10, thereby enabling lid 12 to be fixed in place. This configuration allows the side walls of housing 10 to absorb impacts acting on the sides of washing machine 1, thereby effectively reducing the load on the washing machine.

[0058] It is preferable that the fifth buffering section 350 protrudes less in the left-right direction than the first buffering section 310. By adopting such an embodiment, it becomes possible to absorb impacts only in the vicinity of the left end 11A1 and the right end 11A2 of the top surface 11 of the housing 10. As a result, it is possible to prevent an impact from being applied to the center of the top surface 11 of the housing 10, where the width in the left-right direction is narrower due to the laundry inlet 11X or the like, and to prevent the end of the laundry inlet 11X from being deformed.

[0059] The fifth buffering section 350 having a smaller protrusion amount in the left-right direction than the first buffering section 310 means that the left-right length of the fifth buffering section 350 is smaller than the left-right length of the first buffering section 310. The left-right length of the fifth buffering section 350 is preferably, for example, no more than twice the distance from the first end 11A of the top surface 11 of the housing 10 to the adjacent laundry inlet 11X. On the other hand, the first buffering section 310 is preferably wide in order to distribute the stress acting on the first corner 11C, and in one example, the left-right length of the first buffering section 310 is preferably at least twice that of the fifth buffering section 350.

[0060] The fifth buffer section 350 extends, for example, from the first buffer section 310 in the rear direction to a region that is at least ¼ of the length of the buffer material 300 in the front-to-rear direction. The fifth buffer section 350 preferably extends from the first buffer section 310 in the rear direction to a region that is at least ¼ and at most ¾ of the length of the buffer material 300 in the front-to-rear direction.

[0061] It is preferable that the vertical length of fifth buffering section 350 is smaller along the front-rear direction. By adopting such an embodiment, lid 12 can be fixed along upper surface 350B of fifth buffering section 350 in an open state.

[0062] The lid 12 may be fixed to the fifth buffer portion 350 with tape or the like.

[0063] As shown in FIG. 8, the cushioning material 300 further includes a planar support substrate 360 ​​extending in the vertical and horizontal directions, and the first buffer section 310, the second buffer section 320, the third buffer section 330, the fourth buffer section 340, and the fifth buffer section 350 are each arranged on the washing machine 1 side of the support substrate 360.

[0064] 10 and 11 are perspective views schematically illustrating the appearance of washing machine 1 having a round lid on which cushioning material 300 is placed. While FIG. 7 shows a case where washing machine 1 has a rectangular lid 12, cushioning material 300 can also be applied to a case where lid 12 is a round lid. As shown in FIGS. 10 and 11, even when lid 12 is circular (round lid), when stress is applied from above to washing machine 1 secured in an open state by cushioning material 300, the stress is transmitted continuously to second cushioning portion 320, first cushioning portion 310 of cushioning material 300, and first corner 11C of top surface 11 of housing 10, thereby preventing the stress from being transmitted to lid 12. First corner 11C of top surface 11 of housing 10 has a higher strength than lid 12, and therefore, when stress is applied from above to washing machine 1 packaged using cushioning material 300, the load on washing machine 1 can be reduced.

[0065] Next, the bottom part 400 will be described with reference to FIGS.
