Description

[Technical field]

[0001] The present disclosure relates to home appliances, refrigerators, and vacuum cleaners. [Background technology]

[0002] From the perspective of effective resource utilization, there is a demand to recycle waste plastics into recycled plastics (recycled resins).

[0003] Patent Document 1 discloses an inner box material for a heat-insulating box of a refrigerator or the like, which contains recycled polyethylene terephthalate resin (PET resin) with excellent chemical resistance. Patent Document 1 also discloses that the material on the inside of the inner box is virgin polyethylene terephthalate resin, and the material on the side in contact with the foamed heat-insulating material is polyethylene terephthalate resin containing recycled polyethylene terephthalate resin. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] JP 2002-22352 A Summary of the Invention [Problem to be solved by the invention]

[0005] It is inevitable that foreign matter will get mixed in with recycled resin. For this reason, recycled resin is usually treated to have a color such as black or gray so that the foreign matter exposed on the surface of the recycled resin cannot be seen.

[0006] In addition, recycled resins can raise hygiene concerns, so in products that store food, such as refrigerators, it is currently difficult to accept using recycled resin for the surfaces of parts that may come into direct contact with food.

[0007] The inner box of a refrigerator is formed by vacuum forming. A plate material is prepared by forming two layers of recycled resin (black, gray, etc.) and virgin material (any color can be selected). When the plate material is then vacuum formed, the plate material is stretched at the apexes (corners) and ridges, where there is a large curvature. In the stretched areas, the virgin material is thinner than other areas, and the color of the recycled resin behind it can be seen through.

[0008] The objective of the present disclosure is to increase the proportion of recycled resin used in plastic parts of home appliances that are manufactured by vacuum forming or the like, by making it impossible for users to see that recycled resin is used. [Means for solving the problem]

[0009] The home appliance of the present disclosure comprises a resin part which is a laminated resin member including a recycled resin layer and a virgin resin layer and has a flat portion and a curved portion, the curved portion having a configuration in which the resin structure is stretched toward the flat portion, and the color difference between the curved portion and the flat portion in the virgin resin layer arranged on the surface of the resin part is 2.0 or less.

[0011] Hereinafter, the embodiments will be described with reference to the drawings. EXAMPLES

[0012] FIG. 1 is a front view showing the refrigerator of the first embodiment.

[0013] As shown in the figure, refrigerator body 10 of refrigerator 1 is open at the front and has storage compartments, in this order from the top: refrigerator compartment 2, ice-making compartment 3 arranged side by side on the left and right, upper freezer compartment 4, lower freezer compartment 5, and vegetable compartment 6. Hereinafter, ice-making compartment 3, upper freezer compartment 4, and lower freezer compartment 5 will be collectively referred to as freezer compartment 7.

[0014] The front opening of the refrigerator compartment 2 is opened and closed by rotating refrigerator compartment doors 50a and 50b, which are divided into left and right. The front openings of the ice making compartment 3, the upper freezer compartment 4, the lower freezer compartment 5, and the vegetable compartment 6 are opened and closed by drawer-type ice making compartment door 60, the upper freezer compartment door 70, the lower freezer compartment door 80, and the vegetable compartment door 90, respectively. Each of these drawer-type doors is provided with a drawer container. The drawer container can be made of a non-translucent resin material. Door hinges (not shown) are provided at the top and bottom of the refrigerator compartment 2. The upper door hinge is covered with a door hinge cover 16.

[0015] The refrigerator compartment 2 is separated from the ice making compartment 3 and the upper freezer compartment 4 by an insulating partition wall 28. The lower freezer compartment 5 and the vegetable compartment 6 are separated by an insulating partition wall 29. An insulating partition wall 30 is disposed on the front side between the ice making compartment 3 and the upper freezer compartment 4 and the lower freezer compartment 5. The insulating partition wall 30 is disposed to close the gap between the lower surface of the ice making compartment door 60 and the upper freezer compartment door 70 and the upper surface of the lower freezer compartment door 80, thereby preventing air from circulating inside and outside the compartment. An insulating partition wall 31 is disposed between the ice making compartment door 60 and the upper freezer compartment door 70. The insulating partition wall 31 is disposed to close the gap between the ice making compartment door 60 and the upper freezer compartment door 70, thereby preventing air from circulating inside and outside the compartment. Further, a heat insulating partition wall 36 is rotatably attached to the inside of the refrigerator compartment door 50a on the refrigerator compartment door 50b side (the right end inside of the refrigerator compartment in FIG. 1). The heat insulating partition wall 36 is intended to close the gap that occurs between the refrigerator compartment doors 50a, 50b when the refrigerator compartment doors 50a, 50b are closed, thereby preventing air from circulating between the inside and outside of the refrigerator.

[0016] FIG. 2 is a partial front view showing the inside of the refrigerator of this embodiment.

[0017] As shown in this figure, a space surrounded by the inner box 210 and the refrigerator compartment doors 50a and 50b in FIG. 1 is provided inside the refrigerator body 10, and a cold air duct panel 220, a food shelf 230, an ice making water container 240, and a chilled compartment 250 are arranged therein. The outer surface of the refrigerator 1 is configured by an outer box 300 formed of a metal such as a steel plate. A heat insulating material such as a foam heat insulating material or a vacuum heat insulating material is provided between the inner box 210 and the outer box 300. The inner box curved surface portion 210a and the inner box protruding portion 210c are parts of the inner box 210. The inner box curved surface portion 210a is exposed above the cold air duct panel 220. The inner box protruding portion 210c supports both ends of the food shelf 230.

[0018] Inner box curved surface portion 210b shown in Fig. 5 described later is covered with cold air duct panel 220. Therefore, it can be said that at least inner box curved surface portion 210b is covered with cold air duct panel 220. Since inner box curved surface portion 210b is at a height that is easily visible to the user, cold air duct panel 220 in Fig. 2 can effectively prevent a decrease in design caused by providing inner box 210 with a recycled resin layer.

[0019] It should be noted that the items placed on food shelf 230 are not limited to food, and food shelf 230 may simply be called a "shelf."

[0020] FIG. 3 is a partial perspective view showing the inside of the refrigerator of this embodiment.

[0021] In this figure, the same configuration as in FIG. 2 is shown from a different angle.

[0022] FIG. 4 is a partial front view showing refrigerator 1 of FIG. 2 with the food shelf removed.

[0023] 4, the cold air passage panel 220 is an integral part, and covers the wall surface at the back of the inner box 210. The cold air passage panel 220 has four cold air openings. The inner box 210 has an inner box protrusion 210c.

[0024] FIG. 5 is a cross-sectional view showing the inside of the refrigerator 1 of FIG.

[0025] 5 shows chilled shelf board 510 which covers the upper surface of ice-making water container 240 and chilled compartment 250 in FIG. 4, and heat-insulating partition wall 28 which constitutes the bottom surface of refrigerating compartment 2. Also shown are legs 520 which are located at the bottommost part (outside of the refrigerator) of refrigerator body 10. Inner box 210 has inner box curved surface portion 210b.

[0026] FIG. 6 is a partial front view showing the refrigerator in FIG. 4 with cold air passage panel 220 removed.

[0027] As shown in Fig. 6, inner box 210 has inner box curved portions 210a, 210b, inner box convex portion 210c, and inner box vertex portion 210d. Inner box curved portion 210a is a curved portion connecting the rear surface and top surface of the inner box. Inner box curved portion 210b is a curved portion connecting the rear surface and side surface of the inner box. Inner box vertex portion 210d is a curved portion connecting inner box curved portion 210a and inner box curved portion 210b.

[0028] FIG. 7 is a schematic cross-sectional view showing a two-layer resin member formed by vacuum forming.

[0029] In this figure, resin member 710 is composed of recycled resin layer 712 and virgin resin layer 714. Curved surface portion 710b is a curved portion that corresponds to inner box curved surfaces 210a, 210b and inner box apex portion 210d of inner box 210 in Figure 6. Flat surface portion 710a is the other portion, which is a flat surface portion.

[0030] When manufacturing the inner box 210 of the refrigerator 1 of this embodiment, first, a flat laminated resin member is formed by two-layer molding using a recycled resin material and a virgin resin material. Then, the obtained flat laminated resin member is deformed into the shape of the inner box by vacuum molding.

[0031] In this specification, the recycled resin material refers to a resin material containing recycled resin, for example, a resin material with a recycled resin ratio of 20% by mass or more, preferably 50% by mass or more, and most preferably 100% by mass. Also, the virgin resin material refers to a resin material with a lower recycled resin ratio than the recycled resin material, for example, less than 20% by mass, preferably 10% by mass or less, and most preferably 0% by mass (unused material that has never been used in a product). When producing a resin member 710 that may come into contact with food, such as the inner box 210, 0% is preferable from the viewpoint of ensuring hygiene.

[0032] Recycled resin materials may be black, gray, etc. due to the influence of impurities. On the other hand, virgin resin materials can be freely colored and toned.

[0033] When the resin member 710 is used as the inner box 210 of the refrigerator 1, by disposing the virgin resin layer 714 on the inside of the refrigerator, it is possible to prevent the color of the recycled resin layer 712 from being recognized when a user looks inside the refrigerator, and it is also possible to prevent the recycled resin from coming into direct contact with food ingredients.

[0034] In curved portion 710b, which is a portion bent by vacuum forming, the resin is stretched, and the thickness of virgin resin layer 714 may become smaller than that of flat portion 710a. In this case, the color of recycled resin layer 712 may be visible. In inner box curved portions 210a, 210b, inner box convex portion 210c, and inner box apex portion 210d of inner box 210 shown in FIG. 6, the resin is easily stretched during vacuum forming, and the thickness of virgin resin layer 714 often becomes smaller. Of these, inner box apex portion 210d is particularly easily stretched and is likely to become thinner.

[0035] In this embodiment, the color of the virgin resin layer 714 arranged on the surface of the resin member 710 is selected so that the color difference between the flat surface portion 710a and the curved surface portion 710b is 2.0 or less, preferably 1.5 or less. In addition, the virgin resin layer 714 has a higher brightness than the recycled resin layer 712.

[0036] In addition, the virgin resin layer 714 or the recycled resin layer 712 preferably contains a pigment in an amount of, for example, 2 parts by weight to 10 parts by weight, based on 100 parts by weight of the virgin resin material. A more preferred amount is 3 parts by weight to 7 parts by weight. Titanium dioxide is preferred as the pigment. For example, polypropylene can be used as the virgin resin layer 714.

[0037] Here, the color difference is calculated in accordance with JIS K 5600-4-6:1999 "General test methods for paints - Part 4: Visual properties of coatings - Section 6: Colorimetry (calculation of color difference)" and the lightness is calculated in accordance with JIS Z 8721-1993 "Method of displaying color - Display by three attributes."

[0038] When the color difference is 2.0 or less, preferably 1.5 or less, it is difficult for the user to distinguish the difference in color, and the user is unlikely to perceive an unnatural color difference. In addition, it is desirable to increase the brightness of the virgin resin layer 714, since this makes it difficult to visually recognize the color of the recycled resin layer 712 at the back. The color difference and brightness can be adjusted, for example, by adjusting the light transmittance and thickness of the recycled resin layer 712 that forms the curved portion 710b, or by adjusting the color of the recycled resin layer 712.

[0039] Furthermore, it is desirable to provide a mosaic pattern, marble pattern, or other pattern in which multiple colors are irregularly arranged on the surface of the virgin resin layer 714, because this makes the color of the recycled resin layer 712 less noticeable even if the color of the recycled resin layer 712 shows through. In this case, it is preferable that the color of the irregularly arranged pattern is the same as or similar to the color of the recycled resin layer 712, or includes black and / or gray.

[0040] In this embodiment, the inner box 210 formed by vacuum molding is shown as an example, but the present invention is applicable to resin parts formed by a molding method in which the thickness of the curved part (curved surface part) of the resin is smaller than that of the other parts as a result of deforming the resin that is one or both outermost layers of the plate-like virgin resin layer 714, and also to products including this resin part, particularly home appliances. As described above, it is considered that the thickness of the inner box apex part 210d connecting the two inner box curved surface parts is more likely to be thinner than the inner box curved surface parts 210a, 210b connecting the two flat surfaces. For this reason, from the viewpoint of design, it is preferable to design the thickness so that the inner box apex part 210d is not see-through (for example, the color difference with the flat surface part is 2.0 or less, preferably 1.5 or less). In this case, it is easy to prevent the recycled resin layer 712 from being seen through the entire inner box 210.

[0041] Also, it is preferable to make only a part of the inner box curved surface parts 210a, 210b and the inner box apex part 210d opaque and cover the remaining parts with other parts from the viewpoint of both design and thin-walled inner box. For example, the inner box curved surface parts 210a, 210b are designed to be opaque, while the inner box apex part 210d is made transparent (for example, the color difference with the flat part is more than 2.0 or more than 1.5). At the same time, the inner box apex part 210d can be covered by disposing an opaque structure such as the cold air duct panel 220 on the side where the user observes the inner box apex part 210d (the front side in the case of the refrigerator 1). In this case, it is possible to suppress the increase in the thickness of the inner box 210 and suppress the decrease in the content volume of the refrigerator 1, while suppressing the transparency of the recycled resin layer 712. Other opaque structures include the above-mentioned pull-out container disposed in the vegetable compartment 6 in this embodiment. This drawer container can cover the inner box curved surfaces 210a, 210b and inner box apex 210d at the lower part of the inner box 210.

[0042] In addition, a method of preventing the see-through is considered by making the thickness of the flat laminated resin member prepared by two-layer molding uneven, that is, by preparing the thickness of the part that is expected to become thin by vacuum molding or the like thick in advance. In this case, since the part is made thick in advance, it becomes difficult to deform during vacuum molding, and the vicinity of the part that was made thick in advance is stretched, so that it is difficult to reduce the possibility of the see-through. For this reason, it is preferable that the thickness of the laminated resin member prepared in advance is uniform.

[0043] (Variation 1) FIG. 8 is a partial front view showing a modified example of the cold air passage panel.

[0044] In this figure, like FIG. 4, the food shelf is removed.

[0045] In Fig. 8, unlike Fig. 4, the upper part of the cold air passage panel 820 covers the inner box curved surface part 210a of Fig. 4. This makes it possible to prevent the user from noticing the color of the recycled resin used for the inner box curved surface part 210a even if it is visible through the product.

[0046] (Variation 2) FIG. 9 is a partial front view showing the inside of the refrigerator of the second modification.

[0047] In this figure, a food shelf 930 is shown installed.

[0048] In Fig. 9, support cover 930a is attached to the underside of both ends of food shelf 930. This makes inner box protrusion 210c in Fig. 2 less visible to the user. Inner box protrusion 210c also includes a curved portion, so there is a risk that the thickness will be small during vacuum molding and the product will be see-through. Support cover 930a prevents the user from noticing the color of the recycled resin used in inner box protrusion 210c.

[0049] In Figure 9, support cover 930a is provided on the underside of food shelf 930, but refrigerator 1 of this modified example is not limited to this configuration. Support covers may be provided on the upper surfaces of both ends of food shelf 930, and food shelf 930 may be installed in such a way that the support covers are hooked onto the upper surface of inner box protrusion 210c, and the side surface of inner box protrusion 210c may also be covered by the support covers.

[0050] (Variation 3) FIG. 10 is an exploded perspective view showing a modified example of the food shelf.

[0051] In this figure, a cantilever type food shelf 1011 is used. Food shelf 1011 has an upper surface 1013, side surfaces 1014, and hooks 1015. Food shelf 1011 is configured to be fixed by inserting hooks 1015 into holes 1016 provided in support pillars 1012. Support pillars 1012 consist of a pair on the left and right, and are attached in the vertical direction to both the left and right sides of the surface of cold air passage panel 220 (see FIG. 4) or to both the left and right sides of the back wall of inner box 210 (see FIG. 6). Refrigerated items such as food can be placed on upper surface 1013.

[0052] By using the food shelf 1011 and support pillars 1012 in this figure, it is not necessary to provide the inner box protrusions 210c in Figure 2. This allows the side surface of the inner box 210 to be flat, reducing the area where the virgin resin is thin, and preventing the color of the recycled resin from being noticeable to the user. EXAMPLES

[0053] 11 is an overall perspective view showing the vacuum cleaner of Example 2. Regarding the suppression of the see-through of the recycled resin in this example, the configuration of Example 1 can be adopted as long as it does not cause any problems.

[0054] As shown in this figure, the vacuum cleaner 1100 has a vacuum cleaner main body 1101, a hose joint 1102, a hose 1103, a hand switch 1104 that controls the operation of the vacuum cleaner 1100, an extension tube 1105 connected to the hose 1103, a suction port 1106 that is connected to the extension tube 1105 and sucks in dust on the cleaning surface, and a hand operation unit 1107. The hose 1103 is connected to the vacuum cleaner main body 1101 via the hose joint 1102. The extension tube 1105 has an extendable tube 1105a (zoom pipe). The hand switch 1104 and the hand operation unit 1107 are disposed between the hose 1103 and the extension tube 1105.

[0055] The telescopic tube 1105a has a generally rectangular cross section with chamfered edges, and is produced by blow molding. For such a blow molded body, for example, a multi-layer preform may be produced by two-layer extrusion, and then blow molded to produce an extension tube. When the telescopic tube 1105a is produced by blow molding in this way so that the recycled resin on the inner diameter side and the virgin resin on the outer diameter side are laminated, the resin may be stretched at the corners (curved surfaces) of the generally rectangular cross section of the telescopic tube 1105a, and the thickness of the virgin resin arranged on the outside may become smaller. In this case, the color of the recycled resin may be visible through the tube.

[0056] In this embodiment, the color of the virgin resin is selected so that the color difference between the straight side portions (flat portions) and the corner portions (curved portions) in the substantially rectangular cross section of the expandable tube 1105a is 2.0 or less, preferably 1.5 or less. When the color difference is 2.0 or less, preferably 1.5 or less, the user cannot normally recognize the difference in color, so the color of the recycled resin placed inside can be prevented from showing through. In addition, it is desirable to increase the brightness of the virgin resin, since this makes it difficult to see the color of the recycled resin at the back.

[0057] Furthermore, it is desirable to provide a pattern such as a mosaic design on the surface of the virgin resin, since this makes the color of the recycled resin less visible even if it shows through.

[0058] In addition, it is desirable that the outer circumference of the cross section including the curved and flat portions of the telescopic tube 1105a, i.e., the substantially rectangular cross section of the telescopic tube 1105a, is longer in the curved portion than in the flat portion. This increases the radius of curvature of the curved portion. The larger the radius of curvature of the curved portion, the more it is possible to suppress the curved portion from being stretched during blow molding, the more the thickness of the virgin resin layer can be maintained, and the more it is possible to prevent the color of the recycled resin placed inside from showing through. Furthermore, it is most desirable that the cross-sectional shape of the telescopic tube 1105a is circular. This is because, when the cross-sectional shape is circular, there are no flat portions, and the force applied in the circumferential direction of the cross section during blow molding is uniform, so the wall thickness of the telescopic tube 1105a is uniform.

[0059] In addition, examples of home appliances to which the resin part of the present disclosure can be applied include refrigerators, vacuum cleaners, washing machines, microwave ovens, and the like.

[0060] Examples of recycled and virgin resin materials include polyethylene (PE), polypropylene resin (PP), acrylonitrile butadiene styrene resin (ABS resin), and polyethylene terephthalate resin (PET resin).

[0061] As described above, a resin part produced by vacuum molding, blow molding, or the like has a structure in which the resin structure at the curved surface portion is stretched toward the flat surface portion of the resin part. Here, the resin structure refers to a fine structure such as a molecular structure of a resin. The resin structure formed by stretching in vacuum molding, blow molding, or the like has a fine structure that can be distinguished from the higher-order structure formed by injection molding.

[0062] The reason why the microstructure of the resin tissue differs between vacuum molding, blow molding, etc. and injection molding is as follows.

[0063] In vacuum molding, blow molding, etc., the resin in a solid state is heated and softened before deformation processing, so that a tensile force acts in a certain direction, especially on the curved surface, and the resin structure is stretched, leaving its fine structure. In contrast, in injection molding, the resin in a fluid state is injected into a mold and solidified, so the orientation of the molecules that make up the resin is influenced by the direction of the resin flow in the mold. Therefore, as described above, the resin structure can be distinguished between vacuum molding, blow molding, etc. and injection molding. [Explanation of symbols]
