Technical Field

[0001] The present disclosure relates to a shelf of a cooling store and the cooling store. Background Art

[0002] For example, Japanese Patent Application Laid-Open No. 2008-14564 describes a refrigerator including a shelf including a glass plate as a component. Summary of the invention

[0003] On the shelves of the cooling chamber, cooling objects such as food are placed, and therefore, high strength may be required for the shelves.

[0004] In a shelf including a glass plate as a component, a resin frame is installed at the end of the glass plate to protect the end of the glass plate or to improve the appearance. Since the resin frame is lower in strength than the glass plate, it is required to improve the strength of the frame in order to improve the strength of the shelf.

[0005] In addition, in a shelf having a glass plate and a frame for holding the end of the glass plate, it is particularly desired that the frame be easily visible to the user without spoiling the appearance.

[0006] In the present disclosure, an object is to provide a shelf that is suitable for use in, for example, a cooling storage and has both strength and appearance.

[0007] The present disclosure relates to a cooling storage shelf comprising: a glass plate having an end edge portion extending in one direction; and The frame body has an insertion portion, and the insertion portion includes an insertion groove for inserting one end edge portion. The insert has: an upper plate portion located on an upper side in a thickness direction of one end edge portion; a lower plate portion located at a lower side in a thickness direction of one end edge portion; an outer portion connecting the upper plate portion and the lower plate portion at the outer side of one end edge portion and forming an insertion groove together with the upper plate portion and the lower plate portion; and A plurality of ribs connect the upper plate portion and the lower plate portion in the thickness direction of the glass plate in the insertion groove. The insertion portion is configured such that a high-density portion exists at an end portion of the insertion groove in one direction, and the number of ribs arranged per unit length in the high-density portion along one direction is greater than that in the central portion in one direction.

[0008] According to one aspect of the present disclosure, it is possible to provide a shelf having both strength and appearance, which is suitable for use in a cooling storage or the like, for example. BRIEF DESCRIPTION OF THE DRAWINGS

[0010] Hereinafter, various embodiments of the present disclosure will be described with reference to the accompanying drawings. In the following description, the same reference numerals are used for the same components. Their names and functions are also the same.

[0011] In the present embodiment, a cooling storage 1 having more than one cooling chamber is taken as an example for explanation. In the present disclosure, a "cooling storage" refers to any object having an internal space (cooling chamber) whose temperature is lower than the external air temperature and which can lower the temperature of the stored items. The cooling storage may be, for example, a refrigerator or a freezer. The cooling storage may have only one cooling chamber or may have multiple cooling chambers. In the case where the cooling storage has multiple cooling chambers, the multiple cooling chambers may also include at least two of a refrigerating chamber, a freezing chamber, a vegetable chamber, a chilled chamber, a slightly frozen chamber, and the like.

[0012] (Overall structure of cooling storage) First, the overall structure of the cooling storage 1 according to the present embodiment will be described. Figure 1 1 is a diagram showing the appearance of the cooling room 11 of the cooling store 1 when viewed from the front. Figure 1In the figure, a door provided on the front of the cooling storage 1 is omitted.

[0013] The outer shape of the cooling storage 1 is mainly composed of a shell 10 (for example, an insulated shell). The shell 10 forms a storage space of the cooling storage 1. The storage space formed by the shell 10 is divided into a cooling room (refrigerating room) 11 as a storage space of the upper layer and other cooling rooms (freezing room 12 and vegetable room 13) by a partition 2 extending in the horizontal direction.

[0014] Thus, the cooling storage 1 according to the present embodiment includes the cooling chamber 11. Figure 1 In the embodiment, the cooling room (refrigerating room) 11 is located on the upper side of the cooling storage 1, and the freezing room 12 and the vegetable room 13 are located on the lower side of the cooling storage 1. However, the arrangement of the cooling rooms is not limited to this.

[0015] In the present embodiment, the surface provided with the door is referred to as the front or front of the cooling storage. Furthermore, with the front as a reference, based on the configuration of the cooling storage 1 set in a normal state, the surfaces of the cooling storage 1 are referred to as the upper surface, the side surface, the back surface, and the bottom surface. With regard to the front and back, left and right, up and down directions, it refers to the direction when the user using the cooling storage 1 observes from the front side of the cooling storage. In addition, when the cooling storage 1 is set on a horizontal plane, when the cooling storage 1 is observed from the front, the left and right direction (the lateral direction orthogonal to the up and down direction) is the left and right direction of the cooling storage 1. In addition, when the cooling storage 1 is placed on the setting surface, the up and down direction of the cooling storage 1 (the longitudinal direction orthogonal to the left and right direction) is the up and down direction of the cooling storage 1. In addition, in the description of the components such as the shelf 4 and the glass plate 5 arranged in the cooling storage 1, it also refers to the up and down, left and right directions, etc. in the state where each component is arranged on the cooling storage 1 set on the horizontal plane.

[0016] A plurality of shelves 4 are provided in the cooling chamber 11. The cooling chamber 11 is divided into small spaces by these components.

[0017] The shelf 4 is detachably disposed in the cooling chamber 11. The shelf 4 is supported by the rail 3 or the like provided on the inner side of the side wall of the cooling chamber 11. The number of the shelves 4 disposed in the cooling chamber 11 is not particularly limited.

[0018] <Cooling room shelves> The detailed structure of the shelf 4 arranged in the cooling chamber 11 will be described. Figures 2 to 4 The appearance of the shelf 4 is shown.

[0019] The shelf 4 at least includes a glass plate 5 and a frame 6 .

[0020] (glass plate) The shape of the glass plate 5 is not particularly limited, but the shape of the glass plate 5 shown in the figure is a substantially quadrilateral flat plate. The glass plate 5 forms the main body of the shelf 4. The glass plate 5 may be composed of, for example, a tempered glass plate. Here, tempered glass refers to a glass plate having a surface layer with a higher tension than the inner layer. The method for forming the surface layer with a high tension may be, for example, a quenching method or a chemical strengthening method.

[0021] The glass plate 5 is at least on the front side ( Figure 3 The lower side of the paper in the figure) has a direction (A) (refer to Figure 3 ) extends from one end side 5a (refer to Figure 8 ).

[0022] (Frame) The frame body 6 is a member that protects and supports the end portion (including one end side portion 5a) of the glass plate 5. The frame body 6 may be made of, for example, resin.

[0023] The frame 6 has an insertion portion 60 including an insertion groove 61 (see Figure 7 , Figure 8 ).exist Figures 2 to 4 In the embodiment, the end portion of the glass plate 5 including one end edge portion 5 a is substantially entirely inserted into the insertion groove 61 of the frame body 6 .

[0024] Reference Figure 8 The insertion portion 60 includes: an upper plate portion 62 located on the upper side of one end side portion 5a (glass plate 5) in the thickness direction; a lower plate portion 63 located on the lower side of one end side portion 5a in the thickness direction (glass plate 5); an outer portion 64 connecting the upper plate portion and the lower plate portion on the outer side of one end side portion 5a, and forming the insertion groove 61 together with the upper plate portion 62 and the lower plate portion 63; and a plurality of ribs 65 connecting the upper plate portion 62 and the lower plate portion 63 in the thickness direction of the glass plate 5 in the insertion groove 61. In the present embodiment, the rib 65 may also include all parts and components connecting the upper plate portion 62 and the lower plate portion 63, and further connect the parts other than the upper plate portion 62 and the lower plate portion 63.

[0025] The glass plate 5 is positioned by the rib 65 and inserted into the insertion groove 61 so that one end side portion 5 a reaches the middle of the depth of the insertion groove 61 (the depth from the opening of the insertion groove 61 to the outer side portion 64 ).

[0026] Reference Figure 8In order to reduce the occurrence of shrinkage holes, it is preferred to make the overall thickness of each part (upper plate part 62, lower plate part 63 and outer part 64) constituting the frame 6 (insertion part 60) nearly uniform. This is because the thick part has a large amount of shrinkage due to heat shrinkage after molding, and shrinkage holes (depressions on the surface) are generated in this part. Therefore, it is necessary to deepen the depth of the insertion groove 61 to a certain extent. However, when the depth of the insertion groove 61 is deepened, the strength of the frame 6 (insertion part 60) decreases. In addition, in the case where the frame 6 is a resin molded body, the insertion part 60 may also be deformed due to gravity, etc. after molding, and the width of the insertion groove 61 becomes narrower. Therefore, in this embodiment, in order to improve the strength of the frame 6 and suppress deformation after molding, a rib 65 is provided in the insertion groove 61. "Shrinkage holes" are situations in which the shape changes due to shrinkage during cooling.

[0027] However, shrinkage holes (depressions caused by heat shrinkage after molding) are formed at positions corresponding to the ribs 65 on the surface of the frame body 6 (insertion portion 60 ), which may impair the appearance of the frame body 6 .

[0028] Reference Figure 5 and Figure 6 In the present embodiment, the insertion portion 60 is constructed in such a way that at the end portion 61b in one direction (A) of the insertion groove 61, there is a high-density portion 65c in which the number of ribs 65 arranged per unit length along one direction (A) (rib number density) is greater than that of the central portion 61a in one direction (A).

[0029] Thus, in this embodiment, more ribs 65 are arranged at the inconspicuous end 61b than at the central portion 61a in the left-right direction (equivalent to one direction (A)) of the cooling storage 1 which is easy for the user to notice (easy to be conspicuous). As a result, when the inside of the cooling room 11 is observed from the front, the shrinkage holes (small depressions) on the surface of the frame 6 caused by the ribs 65 are mostly located at inconspicuous positions. Therefore, the aesthetics (appearance) of the cooling storage 1 (the shelf 4 provided in the cooling room 11) can be improved.

[0030] In addition, when an article is placed on the glass plate 5 of the shelf 4, stress is applied to the frame 6 from the glass plate 5. Here, a large stress is easily applied near the end 61b in one direction (A) of the insertion groove 61, which is a portion near the side surface supported by the rail 3, etc. in the cooling chamber 11. Therefore, by providing the high-density portion 65c at the end 61b in one direction (A) of the insertion groove 61, the strength of the frame 6 can be effectively improved.

[0031] In particular, when the shelf 4 is assembled by first manufacturing the frame 6 by resin molding or the like and inserting the glass plate 5 into the insertion groove 61 of the manufactured frame 6, at the time of assembly, since there is a situation where the corner of the glass plate 5 is initially inserted near the end 61b in one direction (A) of the insertion groove 61 of the frame 6, stress is easily applied near the end 61b. Therefore, by providing the high-density portion 65c at the end 61b in one direction (A) of the insertion groove 61, the strength of the frame 6 can be effectively improved.

[0032] In addition, basically, the larger the rib (the cross-sectional area of ​​the rib on the plane perpendicular to the direction in which the rib extends), the larger the shrinkage cavity generated, so in order to improve the aesthetics of the frame 6, it is preferred that the thickness of each rib 65 is as thin as possible. Therefore, for example, a plurality of thin ribs 65 are provided on the high-density portion 65c.

[0033] Here, the area between the central portion 61a and the end portion 61b in one direction (A) (the left-right direction of the cooling storage 1) is set as the middle area 61c. At this time, the relationship between the number density D1 of the ribs in the central portion 61a, the number density D2 of the ribs in the end portion 61b, and the number density D3 of the ribs in the middle area 61c is preferably a relationship expressed by the following formula. D1>D2>D3 In this case, by providing a large number of ribs at the end 61b where the shrinkage cavity is not easily noticeable and is particularly important for the strength of the frame 6, the strength of the frame can be effectively improved without affecting the appearance. In addition, when the ribs 65 are also provided at places other than the end 61b, the strength of the frame is improved, and the deformation of the insertion groove after molding can be suppressed. However, when the light source 7 is provided near the center in the left-right direction of the refrigerator 1, compared with the middle area 61c where the shrinkage cavity is likely to be shadowed, a large number of ribs are provided in the central part 61a where the shrinkage cavity is difficult to be shadowed, thereby effectively improving the strength of the frame without damaging the appearance.

[0034] Therefore, according to the present embodiment, it is possible to provide a shelf having a glass plate and a frame body for holding the end portions of the glass plate, which shelf has both strength and appearance.

[0035] In the present embodiment, the plurality of ribs 65 are provided so that the plurality of ribs 65 are in contact with one end edge portion 5a of the glass plate 5. In this case, the glass plate 5 can be positioned with high accuracy by the ribs 65.

[0036] In the present embodiment, a plurality of ribs 65 extend from the bottom of the insertion groove 61 (the bottom in the depth direction of the insertion groove. The surface on the inner side of the outer portion 64.) to the side of the glass plate 5. In this case, when stress in the up-down direction is applied to the glass plate 5, the stress applied by the glass plate 5 to the frame 6 can be reduced. This is because the distance between the fulcrum of the stress (the end of the frame 6 on the glass plate 5 side) and the point of action (one end edge 5a of the glass plate 5) can be shortened compared to a case where there is no rib 65.

[0037] In this embodiment, refer to Figure 8 At least one of the upper surface 60a of the insertion portion 60 and the lower surface 60b of the insertion portion 60 includes an inclined portion that inclines upward as it moves toward the outside. In this case, compared with the case where the upper surface 60a of the insertion portion 60 and the lower surface 60b of the insertion portion 60 located in the area where the rib 65 is provided are flat surfaces (the upper plate portion 62 and the lower plate portion 63 are flat plate shapes), the rigidity of the insertion portion 60 (especially the bending rigidity in the width direction) can be further improved.

[0038] In this embodiment, refer to Figure 8 The lower surface 60b of the insertion portion 60 includes an inclined portion that tilts upward as it moves toward the outside. The bottom surface of the insertion groove 61 of the insertion portion 60 has a portion that tilts along the inclined portion (the outer surface of the outer portion 64). In this case, since the thickness of the outer portion 64 is less uneven, it is easy to form the frame with high dimensional accuracy.

[0039] <Cooling room> Another aspect of the present disclosure relates to a cooling store, which includes the shelf (eg, shelf 4) according to one aspect of the present disclosure.

[0040] Reference Figure 1 As described above, the cooling store 1 of the present embodiment has the cooling chamber 11 and includes the housing 10 in which the shelf 4 is installed.

[0041] The cooling store 1 may further include a light source 7 disposed above the shelf 4 such as the ceiling of the cooling chamber 11. The light source 7 can emit light downward to illuminate the inside of the cooling chamber.

[0042] In this embodiment, if Fig. 9 As shown, at least one of the plurality of ribs 65 (rib 65a) is located within the range of the light source 7 in the left-right direction (the same direction as the one direction (A)) of the cooling store 1. In this case, the shrinkage hole (depression) 66a generated at the position corresponding to the rib 65a on the surface of the frame 6 is located within the range of the light source 7 in the one direction (A). Here, refer to Fig.10, in one direction (A), the shrinkage cavity 66a located within the range of the light source 7 is unlikely to produce a shadow caused by the light of the light source 7. Therefore, in the cooling chamber 11, the shrinkage cavity 66a located at such a position is unlikely to damage the aesthetics of the frame 6. On the other hand, in the shrinkage 66b located outside the range of the light source 7 in one direction (A), a shadow 67 caused by the light of the light source 7 is produced. Therefore, in the cooling chamber 11, the shrinkage cavity 66b located at such a position is likely to damage the aesthetics of the frame 6. Therefore, for example, in the case where the rib is arranged at a position where the shrinkage cavity is likely to be noticeable other than the end portion in the left-right direction, by arranging the rib to be within the range of the light source 7 in one direction (A), the aesthetics of the frame 6 can be improved.

[0043] In particular, since the recessed portion 66a corresponding to the rib 65a disposed in the center in the left-right direction is easily noticeable, such a rib 65a (recessed portion 66a) is preferably located within the range of the light source 7 in one direction (A).

[0044] Furthermore, even if the positions of the light source 7 (light emitting element 71) and the rib 65 overlap in the left-right direction when viewed from above, a shadow may be generated if they are displaced in the front-back direction. Therefore, it is more preferred that the positions of the light source 7 (light emitting element 71) and the rib 65a are also within the range of the light source 7 (light emitting element 71) in the front-back direction when viewed from above.

[0045] The light source 7 may also include at least one light emitting element 71. In this case, the plurality of ribs 65 preferably include a rib 65a located within the range of the light emitting element in one direction (A). More preferably, the rib 65a is located within the range of the light source 7 (light emitting element 71) in the front-rear direction when viewed from above. Thus, it is more reliable that a shadow is less likely to be generated in the shrinkage hole 66a of the frame body 6, and the shrinkage hole is less noticeable.

[0046] The at least one light emitting element 71 may further include a light emitting element 71 disposed at a position corresponding to each of the plurality of ribs 65a located within the range of the light source 7 in one direction (A) among the plurality of ribs 65. Thus, it is more reliable that a shadow is less likely to be generated in the shrinkage hole 66a of the frame body 6, and thus the shrinkage hole is less noticeable.

[0047] The embodiments disclosed herein should be considered to be illustrative and not restrictive in all aspects. The scope of the present disclosure is not represented by the above description but by the scope of the claims, including the meaning equivalent to the scope of the claims and all changes within the scope.
