In the present embodiment, in the combination of the lower surface portions 23a, 24a, 25a and the upper surface portions 24b, 25b, 26b in which the recessed portion 30 and the groove portion 40 are visible at least in side view, the first curvature radius R1 of the ridge portion 32 and the second radius of curvature R2 of the ridge 44 are set differently. As a result, even if one or both of the vertically aligned doors 21, 22, 23, 24, 25, and 26 are slightly displaced in the front-rear direction within the range of manufacturing tolerances, for example, by an optical illusion, It becomes difficult to perceive the deviation.

In this embodiment, the radius of curvature R2 of the ridges 44 located on the upper surfaces 24b, 25b, 26b is set larger than the radius of curvature R1 of the ridges 32 located on the lower surfaces 23a, 24a, 25a. For example, the curvature radius R2 of the ridge 44 can be set within the range of 2.5 mm to 3.5 mm. Also, the curvature radius R1 of the ridge 32 can be set within a range of 1.5 mm to 2.5 mm. In another embodiment, the radius of curvature R2 of the ridges 44 located on the top surfaces 24b, 25b, and 26b is set smaller than the radius of curvature R1 of the ridges 32 located on the bottom surfaces 23a, 24a, and 25a. can be done.

As shown in FIGS. 5 to 7 and the like, in each of the drawer-type doors 23, 24, 25, and 26, the positions of the upper end surfaces of the respective plate members 233, 243, 253, and 263 are the upper surface portions 23b, 24b, 25b, It is set lower than the position of 26b. Furthermore, in each door 24, 25, 26, the height position of the upper end surface of each plate member 243, 253, 263 can be set between the upper end and the lower end of the ridge 44 or below the ridge 44. . In this embodiment, the height position of the upper end surface of each plate member 243 , 253 , 263 in each of the doors 24 , 25 , 26 is set between the upper end and the lower end of the ridge 44 . At least part of the rear portion of the upper end surface of each plate member 233, 243, 253, 263 of each door 23, 24, 25, 26 is covered from above by the front end portion of the frame members 232, 242, 252, 262. ing.

In this embodiment, the vertical cross-sectional shape of the recessed portion 30 and the groove portion 40 is designed to be substantially constant from the right end to the left end of each door 23, 24, 25, 26. As shown in FIG. That is, in plan view, the rear wall portion 42 of the groove portion 40 and the rear end portion of the recess portion 30 form a straight line extending in the left-right direction. That is, the depth of the recessed portion 30 and the depth of the groove portion 40 are each set constant in the horizontal direction.

Furthermore, in this embodiment, the radius of curvature R1 of the ridge 32 and the radius of curvature R2 of the ridge 44 are designed to be substantially constant from the right end to the left end of each door 23, 24, 25, 26.

Next, design processing applied to at least one of the doors 21, 22, 23, 24, 25, 26 will be described. In this embodiment, at least the vegetable compartment door 23 is designed. In this case, the door 23 is subjected to so-called hot stamping, although the details are not shown. Hot stamping, which is also called foil stamping, is a technique of applying foil to a processed surface and applying heat and pressure to adhere and fix the foil to the processed surface for decoration. The foil is formed, for example, by vapor-depositing metal on a resin thin film, and can add metallic luster to the processed surface. Therefore, when light hits the hot-stamped surface, the light is reflected, creating a gorgeous effect. For example, the foil can be applied to the work surface with a silicone roller.

FIG. 8 is a right side view showing an enlarged configuration inside circle III of FIG. 5 of the vegetable compartment door 23. As shown in FIG. The vegetable compartment door 23 has a front surface portion 100 , a plurality of curved surface portions 101 and 102 in this case, and a top portion 103 at a front end portion, in this case a tip portion 911 , at the upper end portion of the frame member 232 . Of the two curved surface portions 101 and 102 , the front curved surface portion 101 is called a first curved surface portion 101 and the rear curved surface portion is called a second curved surface portion 102 .

Front portion 100 forms the front surface of tip portion 911 . The first curved surface portion 101 forms an upwardly convex curved surface and connects the upper end portion of the front surface portion 100 and the front end portion of the second curved surface portion 102 . The second curved surface portion 102 forms an upwardly convex curved surface and connects the rear end portion of the first curved surface portion 101 and the front end portion of the top portion 103 . The top portion 103 forms the upper end surface of the tip portion 911 . In this embodiment, the top 103 forms a horizontal surface.

The front portion 100 forms a surface that is generally vertical in the front-rear direction and slopes forward toward the bottom. Note that in other embodiments, the front portion 100 may form a surface that is substantially perpendicular to the front-rear direction. The front part 100 is positioned above the upper end of the plate member 233 and is exposed to the outside, in this case, toward the front of the refrigerator 10 . The front part 100 can be designed. In this embodiment, the front part 100 is hot-stamped, although the details are not shown.

The radius of curvature R3 of the first curved surface portion 101 is set larger than the radius of curvature R4 of the second curved surface portion 102 . For example, the curvature radius R3 can be set within a range of 20 times or less of the curvature radius R4. In this embodiment, the curvature radius R3 of the first curved surface portion 101 is set to 2.0 mm, and the curvature radius R4 of the second curved surface portion 102 is set to 0.2 mm. In another embodiment, the curvature radius R3 of the first curved surface portion 101 can be set within the range of 0.2 mm to 2.0 mm. Also, the radius of curvature R4 of the second curved surface portion 102 can be set within the range of 0.1 to 0.2 mm.

Here, for example, as shown in FIG. 9, a stepped portion 200 may be provided between the upper end portion of the front portion 100 and the top portion 103 to connect them in a stepped manner. In this case, the design becomes linear and planar, and the light reflected by the hot-stamped front part 100 does not spread to the top part 103, and there is a possibility that the advantage of light presentation cannot be fully utilized. Also, depending on the position where the joint of the mold of the frame member 232 is provided, the hot-stamped foil may be caught in the burrs generated at the joint position, or the edge of the foil may become wavy rather than straight. There is a risk of getting stuck.

According to this embodiment, when the door 23 is observed from above, the front surface portion 100 is glossy due to hot stamping, that is, the light reflected by the front surface portion 100 is diffusely reflected by the surface of the first curved surface portion 101 having a large radius of curvature. , the design of the refrigerator 10 is produced more luxuriously. Also, when the foil is pasted with a silicon roller in hot stamping, the edges of the foil are neatly disposed by the presence of the first curved surface portion 101 and the second curved surface portion 102, so that the foil is caught in burrs. Also, the edges of the foil are prevented from becoming wavy.

In addition, in the upper surface portions 21b, 22b, 24b, 25b, and 26b of the doors 21, 22, 24, 25, and 26, a similar configuration may be employed in which a plurality of stages of curvature are set at the tip portions. Also, the same configuration may be adopted for the lower surface portions 21a, 22a, 23a, 24a, 25a, and 26a of the doors 21, 22, 23, 24, 25, and 26. As shown in FIG. In particular, when a usage pattern in which the user looks down on the upper surface portions 21b, 22b, 24b, 25b, and 26b or a usage pattern in which the user looks up on the lower surface portions 21a, 22a, 23a, 24a, 25a, and 26a from below, A similar effect is exhibited.

Furthermore, the above configuration can be applied not only to the doors 21, 22, 23, 24, and 25, but also to any member to which hot stamping is applied. For example, in the case of the refrigerator 10, a chilled chamber container provided in the refrigerating chamber 12, a frame portion of the shelf board, pockets provided inside the refrigerating chamber doors 21 and 22, a duct installed on the back surface of the refrigerating chamber 12, and the like. can be applied to various resin members.

According to the present embodiment described above, the refrigerator 10 is arranged adjacent to and below the doors 21, 22, 23, 24, 25 and the doors 21, 22, 23, 24, 25. doors 23, 24, 25, 26; The one door 23, 24, 25 is provided in front of the first surface portion 50 and the first surface portion 50 in the lower surface portions 23a, 24a, 25a, and is provided in the vertical direction central portion of the one door 23, 24, 25. It has a recessed portion 30 as a first recessed portion formed by recessing toward it. The other doors 24, 25, 26 are provided on the upper surface portions 24b, 25b, 26b facing the lower surface portions 23a, 24a, 25a, and the second surface portion 60, which faces the first surface portion 50, and the second surface portion 60, which is provided in front of the second surface portion 60. and a groove portion 40 as a second recessed portion formed by being recessed toward the center portion in the vertical direction of the other doors 24 , 25 , 26 . The rear end portion of the first recessed portion and the rear end portion of the second recessed portion are positioned on a single imaginary straight line L1 extending vertically in a side view. The position of the front end portion of the first surface portion 50 and the position of the front end portion of the second surface portion 60 are set differently in the front-rear direction.

That is, the rear ends of the pair of recessed portions 30, 40 facing each other of the vertically arranged doors 23, 24, 25, 26 overlap vertically, but the pair of facing surface portions 50, 60 are symmetrically arranged. Not designed. As a result, even if the front and rear positions of the vertically aligned doors 23, 24, 25, and 26 are slightly shifted within the range of manufacturing tolerance, the shift is less likely to be recognized by the user, and the doors 23, 24, 25, and 26 are not easily recognized. appear to be aligned. Therefore, the appearance of the refrigerator 10 is improved. In addition, the burden of assembling the doors 23, 24, 25, and 26 in the manufacturing process is reduced, and the yield rate of the refrigerator 10 is improved, so that the manufacturing cost can be suppressed.

Further, according to this embodiment, one of the doors 23 , 24 , 25 has the ridge portion 32 as the first ridge portion between the recessed portion 30 as the first concave portion and the first surface portion 50 . The other doors 24, 25, 26 have a ridge 44 as a second ridge between the groove 40 as the second concave portion and the second surface 60 as the second surface. The ridges 32 and 44 each form a curved surface that is convex forward. The first radius of curvature R1 of the ridge 32 is set different from the second radius of curvature R2 of the ridge 44 .

That is, since the radii of curvature R1 and R2 of the facing ridge 32 and the ridge 44 are different, the pair of facing surfaces 50 and 60 are designed asymmetrically. As a result, the sense of unity in design is maintained as a whole, and slight deviations in the front and rear positions of the upper and lower doors 23, 24, 25, and 26 are more difficult to recognize.

Either one of the first recessed portion and the second recessed portion is a recessed portion 30 that opens forward. The other of the first concave portion and the second concave portion is a groove portion 40 having a front wall portion 41 covering at least a portion of the first concave portion or the second concave portion in a front view.

According to this, the user's fingers can be inserted into the upper surface portions 23b, 24b, 25b, and 26b of the doors 23, 24, 25, and 26 or the lower surface portions 23a, 24a, 25a, and 26a, and the user can put his/her fingers on the front wall portion 41. A groove portion 40 is provided in which the A depression 30 is provided at a position facing the groove 40 in the doors 23 , 24 , 25 , 26 arranged to face each other. As a result, when the user pulls out or pushes in the doors 23 , 24 , 25 , 26 , the depression 30 secures a wide finger trajectory, making it easier to insert the hand into the groove 40 . Furthermore, the presence of the front wall portion 41 facilitates the operation of the doors 23, 24, 25, 26 by the user.

In particular, when operating the doors 23, 24, 25, 26 of the storage chambers 13, 14, 15, 16 provided from the center to the bottom in the vertical direction of the refrigerator 10, the user reaches out from above. Become. Therefore, in the case of a design in which the lower portions of the doors 23, 24, 25, and 26 are operated, there is a risk that the user's operation burden will increase.

In contrast, according to the present embodiment, the first recessed portion is the recessed portion 30 provided in the lower surface portions 23a, 24a, 25a of the doors 23, 24, 25 and opening forward. . Further, the second recessed portion is a groove portion having a front wall portion 41 provided on the upper surface portions 24b, 25b, and 26b of the other doors 24, 25, and 26 and covering at least a portion of the second recessed portion in a front view. is 40.

As a result, the portions that receive the user's operation are provided on the upper surface portions 23b, 24b, 25b, and 26b of the doors 23, 24, 25, and 26 instead of the lower surface portions 23a, 24a, 25a, and 26a. The user can easily open and close the doors 23, 24, 25, and 26, thereby improving convenience for the user.

According to this embodiment, the position of the front end portion of the second surface portion 60 is set to the rear of the position of the front end portion of the first surface portion 50 . In other words, the edge portion 44 between the second surface portion 60 and the groove portion 40 has a larger corner than the edge portion 32 between the first surface portion 50 and the recess portion 30. can be expressed.

When operating the doors 23 , 24 , 25 , 26 , the user inserts fingers into the groove 40 from the side of the recess 30 , that is, from above in this case, and grips the front wall 41 . Therefore, compared to the case where the ridge portion 44 is relatively angular, the user's fingers are less likely to touch and feel uncomfortable.

According to this embodiment, the height position of the second surface portion 60 is set equal to or higher than the height position of the tip portion 411 of the front wall portion 41 .

Here, the closer the lower surfaces 23a, 24a, 25a of the upper doors 23, 24, 25 and the upper surfaces 24b, 25b, 26b of the lower doors 24, 25, 26, the better the insulation effect between the doors. increases. Therefore, by setting the height of the first surface portions 50 of the lower doors 24, 25, and 26 to be equal to or higher than the height of the tip portion 411 of the front wall portion 41, the heat insulating effect can be enhanced.

More specifically, the height position of the second surface portion 60 is set to be the same as the height position of the tip portion 411 of the front wall portion 41 .

By making the height position of the second surface portions 60 of the lower doors 24, 25, and 26 the same as the height of the tip portion 411 of the front wall portion 41, when the refrigerator 10 is viewed from the front side or side side, the It can give you a cleaner look and give you a more sophisticated impression.

(Second embodiment)
Next, a second embodiment will be described with reference to FIG. In this embodiment, in a set of vertically aligned doors 23, 24, 25, 26, concave portions and first surface portions formed on the lower surfaces 23a, 24a, 25a of the upper doors 23, 24, 25 50, or between the recessed portions formed on the upper surface portions 24b, 25b, 26b of the lower doors 24, 25, 26 and the second surface portion 60, or both. ing. In this case, the slope is inclined toward the central portion of each door 23, 24, 25, 26 in the vertical direction as it goes forward.

In this embodiment, a slope portion 70 is formed between the second surface portion 60 and the groove portion 40 formed in the upper surface portions 24 b , 25 b , 26 b of the lower doors 24 , 25 , 26 . The slope portion 70 forms a surface that becomes lower toward the front, and extends from the upper end portion of the rear wall portion 42 of the groove portion 40, that is, the portion corresponding to the second curvature change point P2 in the first embodiment, to the front end of the second surface portion 60. It connects up to the part.

According to this embodiment, one of the doors 23, 24, 25 and the other doors 24, 25, 26, in this case, the one door 23, 24, 25 has a recess as the first recessed portion. 30 and the first surface portion 50, or the groove portion 40 as the second concave portion and the second surface portion 60 are connected, and a ridge portion 32 which is a curved surface convex forward is provided. One of the doors 23, 24, 25 and the other of the doors 24, 25, 26, in this case, the doors 24, 25, 26 have a recess 30 and a first surface 50 as a first recessed portion, or a second recessed portion. It has a slope portion 70 that connects the groove portion 40 as a shape portion and the second surface portion 60 .

In other words, in this embodiment, by forming the slope portion 70 on one of the doors 24, 25, 26, the design near the joint of the upper and lower doors 23, 24, 25, 26 is made asymmetrical in the vertical direction. As a result, even if the front and rear positions of the doors 23, 24, 25, and 26 are slightly shifted within the range of manufacturing tolerance, the front and rear positions of the doors 23, 24, 25, and 26 appear to be aligned as a whole. Therefore, the same effects as those of the above-described embodiment can be obtained.

(Third embodiment)
Next, a third embodiment will be described with reference to FIG. In the present embodiment, either one or both of the first radius of curvature R1 of the ridge 32 and the second radius of curvature R2 of the ridge 44 change in the horizontal direction of the refrigerator 10 . In this case, the difference between the first radius of curvature R1 and the second radius of curvature R2 is set to be larger at the left and right ends of refrigerator 10 and smaller at the center.

In the present embodiment, the second radius of curvature R2 of the ridge 44 varies across the refrigerator 10 in the horizontal direction. Specifically, the second radius of curvature R2 is set larger toward the outer side in the left-right direction of the refrigerator 10 and smaller toward the central portion. The first curvature radius R1 of the ridge portion 32 does not change over the horizontal direction of the refrigerator 10 .

That is, according to the present embodiment, the difference between the first radius of curvature R1 of the ridge 32 as the first ridge and the second radius of curvature R2 of the ridge 44 as the second ridge is is set to be larger than the central portion of refrigerator 10 in the left-right direction.

According to this, the degree of asymmetry in the design of the vertically aligned doors 23 , 24 , 25 , 26 increases in the outer portion of the refrigerator 10 that is directly visually recognized by the user. Therefore, the above effects can be further enhanced.

In another embodiment, the first radius of curvature R1 of the ridges 32 of the doors 23, 24, and 25 is set to be smaller at the laterally outer side of the refrigerator 10 than at the laterally central portion of the refrigerator 10. It's okay to be there.

(Fourth embodiment)
Next, a fourth embodiment will be described with reference to FIG. In each of the above embodiments, the first radius of curvature R1 of the ridges 44 of the upper surfaces 24b, 25b, and 26b is set larger than the second radius of curvature R2 of the ridges 32 of the lower surfaces 23a, 24a, and 25a. However, in this embodiment, the first radius of curvature R1 of the ridges 44 of the upper surfaces 24b, 25b, 26b is set smaller than the radius of curvature R2 of the ridges 32 of the lower surfaces 23a, 24a, 25a.

In this case as well, the first curvature change point P1′, which is the connection portion between the recessed portion 30 and the ridge portion 32, and the second curvature change point P2′, which is the connection portion between the groove portion 40 and the ridge portion 44, are arranged in the vertical direction. are located on the same imaginary straight line L1' extending to .

As a result, even if the front and rear positions of the vertically aligned doors 23, 24, 25, and 26 are slightly deviated within the range of manufacturing tolerances, the deviation is less likely to be recognized by the user. 26 lines appear to be aligned. Therefore, the appearance of the refrigerator 10 is improved. In addition, the burden of assembling the doors 23, 24, 25, and 26 in the manufacturing process is reduced, and the yield rate of the refrigerator 10 is improved, so that the manufacturing cost can be suppressed.

(Fifth embodiment)
Next, a fifth embodiment will be described with reference to FIG. In this embodiment, the shape of the longitudinal section of the recessed portions of the doors 23 , 24 , 25 , 26 changes along the horizontal direction of the refrigerator 10 .

FIG. 13 shows a plan view of the ice making compartment door 24 and the small freezer compartment door 25. As shown in FIG. In this case, the depth of the groove portion 40 is set to be shallower at the laterally outer side of the refrigerator 10 and deeper toward the laterally central portion thereof. That is, the rear wall portion 42 is positioned further forward in the laterally outer side of the refrigerator 10 and positioned further rearwardly in the laterally central portion of the refrigerator 10 . Therefore, the rear wall portion 42 of the groove portion 40 draws a convex arc in which the center portion is received rearward in a plan view. In this case, the position of the front wall portion 41 of the groove portion 40 is basically the same across the width of the refrigerator 10 in the left-right direction.

Further, although the details are not shown, the depth of the recessed portion 30 is also set to be shallower at the laterally outer side of the refrigerator 10 and deeper toward the laterally central portion. That is, the position of the rear end of recess 30 is positioned further forward in the laterally outer side of refrigerator 10 and positioned further rearwardly in the laterally central portion of refrigerator 10 . Therefore, the rear end portion of the recessed portion 30 draws a convex arc in which the center portion is received rearward in a plan view.

According to the present embodiment described above, the depth in the front-rear direction of the recessed portion 30 and the groove portion 40 as the recessed portion is set to be shallower toward the outer side in the left-right direction of the refrigerator 10 and deeper toward the central portion.

Here, since it is considered that the user usually operates the central portion of the doors 23, 24, 25, and 26, by increasing the depth of the recess portion 30 and the groove portion 40 in the central portion, it becomes easier for the user to insert his or her fingers. . This improves the operability for the user. In addition, when the refrigerator 10 is viewed from the side, the depth of the grooves 40 is not too large, so the appearance is neat and sophisticated.

In addition, in each of the above-described embodiments, the recessed portions 30 are provided in the upper surface portions 24b, 25b, and 26b, and the groove portions 40 are provided in the lower surface portions 23a, 24a, and 25a, but the present invention is not limited to this. In another embodiment, the grooves 40 may be provided on the upper surfaces 24b, 25b, 26b and the recesses 30 may be provided on the lower surfaces 23a, 24a, 25a. In yet another embodiment, the grooves 40 may be provided on both the upper surface portions 24b, 25b, 26b and the lower surface portions 23a, 24a, 25a. In this case, for example, the height of the tip of the front wall portion 41 of the groove portion 40 provided in at least one of the upper surface portions 24b, 25b, 26b or the lower surface portions 23a, 24a, 25a is set closer to the bottom portion 43 than the surface portions 50, 60. can be set. Thereby, even if the grooves 40 are provided facing each other, the user can easily insert his or her fingers into the grooves 40 .

The above embodiments are presented as examples and are not intended to limit the scope of the invention. These novel embodiments can be implemented in various other forms, and various omissions, replacements, and modifications can be made without departing from the scope of the invention. This embodiment and its modifications are included in the scope and gist of the invention, and are included in the scope of the invention described in the claims and its equivalents.
