Mode for Carrying Out the Invention

[0009] (Knowledge, etc. on which the present disclosure is based) When the inventors came up with the present disclosure, there was a handle including a rear member having a fastening wall fixed to the front surface of a door with a fastener, and a front member externally fitted to the rear member. By having such a structure, this handle facilitates attaching the front member to the rear member and enables maintaining a good connection state between the front member and the rear member. In addition, since such a handle is formed of two members, it is possible to easily form a thickness dimension that is easy for a user to grip.

[0010] However, in a conventional handle, since a member located on the opposite side of the door, such as the front member, is attached by engaging with a member attached to the door, such as the rear member, the inventors have discovered that the member located on the opposite side of the door may become detached when the door is repeatedly opened and closed. In order to solve this problem, the inventors have arrived at the subject matter of the present disclosure. Therefore, the present disclosure provides a handle and a storage that can suppress detachment of members.

[0011] Hereinafter, embodiments will be described in detail with reference to the drawings. However, detailed descriptions may be omitted more than necessary. For example, detailed descriptions of well-known matters or redundant descriptions of substantially the same configuration may be omitted. This is to avoid making the following description overly redundant and to facilitate understanding by those skilled in the art. Note that the accompanying drawings and the following description are provided to enable those skilled in the art to fully understand the present disclosure, and are not intended to limit the subject matter described in the claims.

[0012] (Embodiment 1) Hereinafter, Embodiment 1 will be described with reference to FIGS. 1 to 8. In the present embodiment, the surface on which the opening of the storage cabinet 1 is provided is defined as the front surface, and the direction toward which the front surface faces is defined as the front direction. In each figure, the reference sign FR indicates the front of the storage cabinet 1 in the installed state, the reference sign UP indicates the upper side of the storage cabinet 1, and the reference sign LH indicates the left side of the storage cabinet 1. Note that in the storage cabinet 1 in the installed state, the vertical direction coincides with the plumb direction, and the front-rear direction and the left-right direction coincide with the horizontal direction. In the following description, each direction is along the direction of the storage cabinet 1.

[0013] [1-1. Configuration] [1-1-1. Configuration of the storage cabinet] FIG. 1 is a front view of the storage cabinet 1 according to the present embodiment. As shown in FIG. 1, the storage cabinet 1 of the present embodiment is a vertical refrigerator. The storage cabinet 1 includes a storage cabinet main body 2. The storage cabinet main body 2 is a box-shaped member having an opening provided on the front surface (front side) and a storage chamber provided inside. The storage cabinet main body 2 is formed of a heat insulating material and a plate-shaped member that forms an outer shell surrounding the heat insulating material. As the heat insulating material, expanded polystyrene, rigid urethane foam, or the like is used. As the plate-shaped member, a metal material such as a stainless steel plate or a hard resin such as an ABS resin is used. Note that the storage cabinet main body 2 may be formed by combining a metal and a hard resin. The opening of the storage cabinet main body 2 is partitioned by a columnar partition member that partitions the vertical direction or the horizontal direction.

[0014] The opening of the storage cabinet main body 2 is closed by a plurality of heat insulating doors 4. The heat insulating door 4 is a rectangular door member that is attached so as to be openable and closable. In the storage cabinet 1 of the present embodiment, a pair of heat insulating doors 4 arranged in the left-right direction is taken as one set, and two sets are provided vertically. These heat insulating doors 4 are arranged with one side surface adjacent to each other.

[0015] Similar to the storage body 2, the heat insulation door 4 is formed by a heat insulating material 5 (Fig. 6) and a plate-shaped outer shell member 7 that forms an outer shell surrounding the heat insulating material 5. For the heat insulating material 5, expanded polystyrene, rigid urethane foam, etc. are used. For the outer shell member 7, a metal material such as a stainless steel plate or a rigid resin such as an ABS resin is used. Note that the storage body 2 may be formed by combining a metal and a rigid resin.

[0016] On each of the upper and lower surfaces of the heat insulation door 4, hinges 8 are provided at positions approaching the other side surface of the heat insulation door 4. Each of the heat insulation doors 4 is a double-opening door that can be opened and closed in the left-right direction of the refrigerator 1 by these hinges 8. In the present embodiment, a set of heat insulation doors 4 is a symmetrically-opening double-leaf door. On each front surface 4A of the heat insulation door 4, handles 10 are provided on the side surfaces adjacent to each other in the left-right direction. The heat insulation door 4 corresponds to the "door" of the present disclosure.

[0017] A machine room 6 is provided above the storage body 2. Inside the machine room 6, devices constituting a refrigeration cycle such as a compressor, a condenser, an expander, and an evaporator are housed, and by driving these, cold air is sent into the storage room.

[0018] Fig. 2 is a perspective view of the heat insulation door 4. In Fig. 2, the handle 10 and the periphery of the handle 10 are shown enlarged. As shown in Fig. 2, the handle 10 is a member that functions as a grip for the user to hold. The handle 10 is attached to the heat insulation door 4 via a handle pedestal 14 provided on the front surface 4A of the heat insulation door 4. The handle pedestal 14 corresponds to the "pedestal" of the present disclosure.

[0019] Fig. 3 is an exploded perspective view of the heat insulation door 4. As shown in FIG. 3, a rectangular opening 9 is provided in the outer shell member 7. The opening 9 is a through hole that penetrates in the plate thickness direction of the outer shell member 7. The opening 9 is located on the front surface 4A of the heat insulation door 4. Here, the handle pedestal 14 is attached to the heat insulation door 4 by being fitted into the opening 9. As a result, the handle pedestal 14 forms a part of the front surface 4A of the heat insulation door 4.

[0020] As shown in FIG. 1, the handle pedestal 14 is a rectangular plate-like member whose longitudinal direction extends in the vertical direction when viewed from the front. The handle pedestal 14 is formed using a resin material, for example, by injection molding or the like. As shown in FIG. 3, the handle pedestal 14 has a shape that is recessed toward the storage cabinet body 2 side, in other words, the inner side of the heat insulation door 4.

[0021] The handle pedestal 14 includes a base portion 20 located on the inner side of the heat insulation door 4. The base portion 20 is formed in a rectangular flat plate shape. An inclined surface portion 22 is provided on each side of the base portion 20. The inclined surface portion 22 has a curved surface shape that rises while inclining forward as it extends outward from each side of the base portion 20 when viewed from the front. Each of the inclined surface portions 22 is connected to each other while forming a curved surface at adjacent locations.

[0022] The handle pedestal 14 includes a peripheral portion 24 that forms the periphery of the handle pedestal 14 when viewed from the front. Each of the inclined surface portions 22 connects the base portion 20 and the peripheral portion 24. An extension portion 28 is provided on the handle pedestal 14. The extension portion 28 is provided at a position overlapping a portion forming the long side among the peripheries of the handle pedestal 14 when viewed from the front. The extension portion 28 extends along the peripheral portion 24 and is located on the base portion 20 side at a predetermined interval from the peripheral portion 24.

[0023] A pedestal protrusion 26 is provided on the handle pedestal 14. The pedestal protrusion 26 is formed in a columnar shape that protrudes forward from the base portion 20. In the present embodiment, two pedestal protrusions 26 are provided on the handle pedestal 14. In the present embodiment, one pedestal protrusion 26 stands up from the upper end portion of the base portion 20 and the inclined surface portion 22 continuous with the upper end portion of the base portion 20. The other pedestal protrusion 26 stands up from the lower end portion of the base portion 20 and the inclined surface portion 22 continuous with the lower end portion of the base portion 20. Each of the pedestal protrusions 26 protrudes forward of the peripheral edge portion 24. That is, the pedestal protrusion 26 protrudes outward from the recessed shape of the handle pedestal 14.

[0024] The side peripheral surface 25 of the pedestal protrusion 26 and the upper surfaces of the base portion 20 and the inclined surface portion 22 are connected by a curved surface 21. That is, at the connection portion between the pedestal protrusion 26 and the base portion 20 and the inclined surface portion 22, a smooth curved surface shape with no large angular change is formed. Thereby, in the storage box 1, when the user cleans the storage box 1, it becomes easy to clean the connection portion between the pedestal protrusion 26 and the base portion 20 and the inclined surface portion 22. The base portion 20 and the inclined surface portion 22 correspond to the "bottom portion" of the present disclosure.

[0025] Thus, in the heat insulation door 4, as a component different from the outer shell member 7, for example, by forming the handle pedestal 14 by resin molding, it becomes possible to form a shape such as the above-described curved surface 21.

[0026] A flat surface 27 substantially parallel to the front surface 4A of the heat insulation door 4 is formed at the tip of the pedestal protrusion 26. A screw hole 29 is provided at the tip of the pedestal protrusion 26. The screw hole 29 is a through hole that is orthogonal to the flat surface 27 provided at the tip of the pedestal protrusion 26 and penetrates the handle pedestal 14 along the front-rear direction. Inside the pedestal protrusion 26, a pair of engaging pieces 23 extending rearward are provided. A claw shape is formed at the tip of the engaging piece 23.

[0027] The heat-insulating door 4 is provided with two plate nuts 60. The plate nut 60 is a plate-shaped member formed of, for example, a metal material. The plate nut 60 is housed inside the outer shell member 7 and is provided so as to be embedded inside the heat-insulating material 5. Each of the plate nuts 60 is exposed to the outside of the outer shell member 7 through the opening 9 in a front view.

[0028] The plate nut 60 is provided with a threaded hole 61. The threaded hole 61 penetrates in the thickness direction of the plate nut 60 and is exposed to the outside of the outer shell member 7 through the opening 9. The plate nut 60 is provided with an engagement hole 63 at a location adjacent to the threaded hole 61. The engagement hole 63 penetrates in the thickness direction of the plate nut 60 and is exposed to the outside of the outer shell member 7 through the opening 9. Each of the plate nuts 60 includes a contact portion 62. The contact portion 62 has a long planar shape extending in the left-right direction.

[0029] Next, a procedure for attaching the handle pedestal 14 to the outer shell member 7 will be described. As shown in FIG. 3, the handle pedestal 14 is attached to the heat-insulating door 4 by being fitted into the opening 9 of the heat-insulating door 4. In this case, the peripheral edge portion 24 abuts on the front surface side of the outer shell member 7, and the extending portion 28 abuts on the back surface side of the outer shell member 7. That is, the edge of the opening 9 is sandwiched between the peripheral edge portion 24 and the extending portion 28. Thereby, the surface of the base portion 20 is disposed substantially parallel to the front surface 4A of the heat-insulating door 4.

[0030] FIG. 4 is a sectional view taken along line IV-IV of FIG. 1. The IV-IV section is a plane passing through substantially the center in the left-right direction of the handle 10. In FIG. 4, for convenience of explanation, the heat-insulating material 5 is shown with dots. When the handle pedestal 14 is fitted into the opening 9, the plate nut 60 is attached to the handle pedestal 14. Specifically, as shown in FIG. 4, one engaging piece 23 is inserted into and engaged with the engaging hole 63, and the other engaging piece is engaged with an end portion located on the opposite side of the contact portion 62 of the plate nut 60. Thereby, the plate nut 60 is fixed to the handle pedestal 14. When the plate nut 60 is fixed to the handle pedestal 14, each of the screw holes 29 is disposed at a position overlapping each of the screw holes 61 in a front view.

[0031] When the plate nut 60 is fixed to the handle pedestal 14, the contact portion 62 extends in the left - right direction and is disposed facing the front surface 4A of the heat - insulating door 4. The contact portion 62 of one plate nut 60 contacts the upper edge portion of the opening 9 from the inner side of the outer shell member 7. The contact portion 62 of the other plate nut 60 contacts the lower edge portion of the opening 9 from the inner side of the outer shell member 7. The upper edge and the lower edge of the opening 9 are sandwiched between the peripheral edge portion 24 and each of the contact portions 62.

[0032] When the handle pedestal 14 is attached to the outer shell member 7, the inside of the outer shell member 7 is filled with a heat - insulating material 5. In the present embodiment, urethane is foamed and filled as the heat - insulating material 5 inside the outer shell member 7. The handle pedestal 14 is adhered and fixed to the outer shell member 7 by the heat - insulating material 5. Thereby, the handle pedestal 14 is configured as a part of the heat - insulating door 4.

[0033] Next, the handle 10 will be described. As shown in FIG. 2, the handle 10 has an elongated shape extending along the vertical direction. The handle 10 is provided with a grip portion 16 that can be gripped by a user at substantially the center in the longitudinal direction. In the present embodiment, the grip portion 16 is formed in a rod - like shape extending linearly along the vertical direction. The handle 10 is provided with fastened portions 18 at both ends in the longitudinal direction. The fastened portions 18 are continuously provided at each of the upper and lower ends of the grip portion 16. The handle 10 is attached to the heat - insulating door 4 by connecting these fastened portions 18 to the handle pedestal 14.

[0034] As shown in FIG. 3, the handle 10 includes a front member 30. The front member 30 is entirely formed of a resin material. The front member 30 includes a main body gripping portion 32. The main body gripping portion 32 forms the front side, in other words, the front surface side, of the gripping portion 16 among the gripping portions 16. In the present embodiment, the rear surface of the gripping portion 16 faces the front surface 4A of the heat insulating door 4, and the front surface of the gripping portion 16 is located on the side opposite to the front surface 4A of the heat insulating door 4 with the rear surface of the gripping portion 16 interposed therebetween. On the front side of the main body gripping portion 32, a continuous one surface shape is formed. The main body gripping portion 32 has a predetermined thickness in the front-rear direction. On the left and right sides of the main body gripping portion 32, side surfaces continuous from the front surface are formed.

[0035] FIG. 5 is an exploded perspective view of the handle 10. FIG. 5 is a view of the handle 10 as viewed from the rear. As shown in FIG. 5, a recess 35 that is recessed forward is provided at the rear portion of the main body gripping portion 32. In the present embodiment, the recess 35 is formed in a rectangular shape when viewed from the rear. The recess 35 is formed over the entire vertical direction of the main body gripping portion 32. The recess 35 is formed with a length dimension shorter than the length dimension of the main body gripping portion 32 in the left-right direction. That is, the edge portion 37 of the recess 35 is disposed at a position facing the front surface 4A of the heat insulating door 4 over the entire circumference. In the following description, the surface of the main body gripping portion 32 where the recess 35 is provided is referred to as a facing surface 31. The facing surface 31 faces the front surface 4A of the heat insulating door 4, and the edge portion 37 of the recess 35 is disposed on the facing surface 31 over the entire circumference.

[0036] Inside the recess 35, a plurality of engaging pieces 36 that protrude along the left-right direction are provided on the inner surface that extends in the vertical direction. Inside the recess 35, a plurality of ribs 38 are provided at the upper end portion (FIG. 6). The front member 30 is reinforced by the provision of these ribs 38. The ribs 38 may be provided at the lower end portion inside the recess 35.

[0037] As shown in FIG. 3, each of the fastened parts 18 is provided on the front member 30. Each of the fastened parts 18 is provided with a housing part 41. The housing part 41 is formed by being recessed from the front surface side of the front member 30 toward the rear surface side in the fastened part 18.

[0038] As shown in FIG. 5, the fastened part 18 is provided with a handle protruding part 42 that protrudes from the facing surface 31 side toward the front surface 4A of the heat insulating door 4. The handle protruding part 42 protrudes rearward from the facing surface 31 of the main body gripping part 32, in other words, toward the front surface 4A of the heat insulating door 4. A flat surface 45 substantially parallel to the front surface 4A of the heat insulating door 4 is formed at the tip of the handle protruding part 42. A screw hole 43 is provided at the tip of the handle protruding part 42. The screw hole 43 is a through hole that is orthogonal to the flat surface 45 provided at the tip of the handle protruding part 42 and penetrates the handle protruding part 42 along the front-rear direction. The screw hole 43 communicates with the internal space of the housing part 41.

[0039] A fastening member 46 such as a screw or a bolt is inserted into the screw hole 43 (FIG. 3). When the fastening member 46 is inserted into the screw hole 43, the tip of the fastening member 46 provided with a screw groove protrudes from the tip of the handle protruding part 42 toward the front surface 4A of the heat insulating door 4. When the fastening member 46 is inserted into the screw hole 43, the head of the fastening member 46 is housed inside the housing part 41. The housing part 41 is closed by a cover member 48. The cover member 48 is fixed to the opening of the housing part 41 by, for example, a snap fit or the like.

[0040] As described above, the front member 30 is provided with the concave part 35 and the pair of housing parts 41 arranged side by side along the longitudinal direction without overlapping each other. As a result, the front member 30 can be formed with a thinner plate thickness for each part than when formed solid, and as a whole, the thickness dimension, which is the dimension along the front-rear direction, can be made thicker.

[0041] Therefore, when the front member 30 is formed of a resin material, it is possible to suppress the occurrence of so-called sink marks while thickening the main body gripping portion 32 and the fastened portion 18. That is, in the storage 1, the front member 30 can be formed without deteriorating the appearance of the main body gripping portion 32 located on the front side of the storage 1. In addition, the front member 30 can be formed to have a predetermined strength while suppressing an increase in the plate thickness of each part.

[0042] FIG. 6 is a perspective view of the back member 50. As shown in FIGS. 3 and 5, the handle 10 includes a back member 50. The back member 50 is a plate-like member formed in a rectangular shape whose longitudinal direction extends along the vertical direction in a front view. The back member 50 is formed of a resin material, like the front member 30. The back member 50 is provided on the back surface of the front member 30. The back member 50 includes a back surface portion 52 that forms a planar shape facing each of the front member 30 and the front surface 4A of the heat insulation door 4. The back surface portion 52 is formed in a rectangular shape, and on the edge portion 53 that forms each side of the back surface portion 52, there is provided an upright surface portion 54 that stands up toward the front member 30.

[0043] Among the upright surface portions 54, the upright surface portion 54 that stands up from the side located at the upper end of the back surface portion 52 is provided with a slit 55 formed by being cut out along the front-rear direction. On the outer surface of the upright surface portion 54 that stands up from the sides located on the left and right of the back surface portion 52 among the upright surface portions 54, a plurality of engaging holes 56 formed by being recessed toward the inner surface side are provided.

[0044] On the surface of the back surface portion 52 facing the front member 30, a plurality of ribs 58 and a rib 59 are provided. The ribs 58 and the rib 59 protrude toward the front member 30. The rib 58 extends along the longitudinal direction of the back member 50 on the back surface portion 52. The rib 59 extends along a direction orthogonal to the longitudinal direction of the rib 58. Note that only the rib 58 that extends along the longitudinal direction of the back member 50 may be provided. Also, for example, the rib 58 may be formed to extend in a direction intersecting the longitudinal direction and a direction orthogonal to the longitudinal direction.

[0045] In the present embodiment, each of the ribs 58 is provided so as to be surrounded by the standing surface portion 54. Each of the ribs 58 is formed with a dimension such that it does not approach the front member 30 more than the standing surface portion 54. The ribs 58 and the rib 59 correspond to the "ribs" of the present disclosure.

[0046] The back member 50 is attached to the front member 30 by being fitted into the recess 35. As shown in FIG. 5, the back member 50 is inserted into the recess 35 such that each of the standing surface portions 54 is along each of the inner surfaces of the recess 35. Then, the engaging piece 36 engages with the engaging hole 56, and thus the back member 50 is fixed to the front member 30. Further, in this case, each of the ribs 38 is inserted into each of the slits 55. As a result, in the handle 10, the gripping portion 16 is formed by two members, namely, the main body gripping portion 32 of the front member 30 and the back member 50. The main body gripping portion 32 of the front member 30 forms the front side of the gripping portion 16, and the back member 50 forms the back side of the gripping portion 16.

[0047] In this way, since the gripping portion 16 is formed by two members, the thickness dimension, which is the dimension along the front-rear direction, is formed thick. As a result, in the handle 10, the gripping portion 16 can be formed with a thickness dimension that is easy for the user to grip without using a high-cost molding method such as gas assist molding or thick-wall molding.

[0048] Next, the procedure for attaching the handle 10 to the heat insulation door 4 will be described. As shown in FIG. 3, the front member 30 is attached to the handle pedestal 14 with the back member 50 attached thereto. More specifically, with the flat surface 45 of the handle protruding portion 42 and the flat surface 27 of the pedestal protruding portion 26 being in contact, the fastening members 46 are inserted into the screw holes 43. The fastening members 46 are inserted into and screwed into each of the screw holes 43, each of the screw holes 29, and each of the screw holes 61. As a result, each of the handle pedestal 14 and the front member 30 is fixed to the heat insulation door 4. After that, each of the accommodating portions 41 is closed by the cover member 48, so that the fastening member 46 is covered.

[0049] As described above, each of the pedestal protrusions 26 protrudes outward from the concave shape of the handle pedestal 14. Each of the handle protrusions 42 protrudes toward the heat insulating door 4 from the gripping portion 16. Thus, when the handle 10 is fixed to the handle pedestal 14, the gripping portion 16 is disposed in front of the front surface 4A of the heat insulating door 4 with a predetermined space S left from the base portion 20 of the handle pedestal 14 along the front-rear direction. Therefore, in the heat insulating door 4, an increase in the depth dimension in which the handle pedestal 14 is recessed toward the outer shell member 7 is suppressed, and a decrease in the thickness dimension of the heat insulating material 5 can be suppressed.

[0050] Here, the space S is a space located between the handle pedestal 14 and the gripping portion 16 of the handle 10. The opposing surface 31 and the back member 50 are disposed to face the space S. The handle protrusion 42 is provided to protrude toward the space S from the gripping portion 16.

[0051] When the handle 10 is attached to the handle pedestal 14, the side peripheral surface 25 of the pedestal protrusion 26 and the side peripheral surface of the handle protrusion 42 are arranged to be flush. Thereby, deposition of dust, dirt, etc. at the connection portion between the handle 10 and the handle pedestal 14 is suppressed. In addition, the handle 10 can provide a shape that is easy for the user to grip and operate.

[0052] [1-2. Operation] Regarding the storage 1 configured as described above, its operation will be described below. The handle 10 is operated by the user when the user opens and closes the heat insulating door 4. In this case, the user grips the gripping portion 16.

[0053] As described above, the grip portion 16 is formed by the front member 30 and the back member 50, and thus has a predetermined thickness dimension. As a result, the handle 10 can provide a shape that is easy for the user to grip and operate.

[0054] As described above, the edge 37 of the recess 35 is disposed on the opposing surface 31 that faces the front surface 4A of the heat insulating door 4 over the entire circumference. Further, since the back member 50 is fitted into the recess 35, the edge 53 is similarly disposed on the opposing surface 31 that faces the front surface 4A of the heat insulating door 4. As a result, in the handle 10, when the user grips the grip portion 16, the edge 37 and the edge 53 are prevented from being pressed against the user's hand. Therefore, the handle 10 can provide a shape that is easy for the user to grip and operate.

[0055] As described above, among the two members forming the handle 10, the main body grip portion 32 of the front member 30 forms the front side of the grip portion 16, and the back member 50 forms the back side of the grip portion 16. When closing the heat insulating door 4, the user mainly presses the front member 30 from the front side of the front member 30 while gripping the handle 10. As described above, the back member 50 is formed smaller than the main body grip portion 32 and is disposed on the back side of the grip portion 16. Therefore, when the heat insulating door 4 is closed, no force is applied to the back member 50 from the front side to the back side, and the back member 50 is prevented from falling off from the front member 30.

[0056] When opening the heat insulating door 4, the user pulls the handle 10 toward the front side while gripping both the back member 50 and the front member 30. That is, the back member 50 is disposed on the side opposite to the pulling direction with the front member 30 sandwiched in the handle 10. Therefore, when the heat insulating door 4 is opened, a force is applied to the back member 50 pressing it toward the front member 30, and the back member 50 is prevented from falling off from the front member 30. In this way, in the heat insulating door 4, the back member 50 is prevented from falling off as it opens and closes.

[0057] As described above, the contact portions between each of the flat surfaces 45 of the handle protrusions 42 and each of the flat surfaces 27 of the pedestal protrusions 26 are located outside the recessed shape of the handle pedestal 14. Accordingly, in the refrigerator 1, when the user cleans the refrigerator 1, it becomes easy to clean the contact portions. For this reason, in the refrigerator 1, it is suppressed that dust, dirt, etc. accumulate at the connection portion between the handle 10 and the handle pedestal 14.

[0058] In addition, the contact portions between each of the flat surfaces 45 of the handle protrusions 42 and each of the flat surfaces 27 of the pedestal protrusions 26 are arranged to protrude forward of the front surface 4A of the heat insulation door 4. For this reason, in the refrigerator 1, it is suppressed that moisture such as condensed water flowing along the front surface 4A enters the connection portion between the handle 10 and the handle pedestal 14.

[0059] As described above, each of the handle protrusions 42 protrudes toward the heat insulation door 4 more than the grip portion 16. Accordingly, for example, when the user grips and operates the upper end portion or the lower end portion of the grip portion 16, it is suppressed that the connection portion between the handle 10 and the handle pedestal 14 is pressed by the user's hand. For this reason, the handle 10 can provide a shape that is easy for the user to grip and operate.

[0060] [1-3. Effects, etc.] As described above, in the present embodiment, the refrigerator 1 includes a handle 10 provided on the heat insulation door 4.

And in the handle 10, by covering the concave portion 35 with the back member 50, a shape having a thickness that is easy for the user to grip and operate can be formed.

[0063] As in this embodiment, the edge 37 of the concave portion 35 and the edge 53 of the back member 50 may be provided at a position facing the heat insulation door 4. Thereby, in the handle 10, when the user grips the gripping portion 16, it is suppressed that the edge 37 and the edge 53 are pressed against the user's hand. Therefore, the handle 10 can provide a shape that is easy for the user to grip and operate.

[0064] As in this embodiment, the front member 30 may be provided with a housing portion 41 that is recessed from the opposite side of the position facing the heat insulation door 4 toward the heat insulation door 4 at a position avoiding the concave portion 35 and houses a fastening member that connects the front member 30 and the heat insulation door 4. Thereby, the front member 30 can be formed with a thinner plate thickness than when formed solid, and as a whole, the thickness dimension, which is the dimension along the front-rear direction, can be formed thicker. Therefore, the front member 30 has a predetermined strength, suppresses the occurrence of so-called sink marks, and can improve the design.

[0065] As in this embodiment, the back member 50 may be provided with ribs 58. Thereby, the back member 50 is reinforced. Therefore, the entire handle 10 provided with the back member 50 is reinforced. Further, by providing ribs 58 on the back member 50 and omitting a reinforcing structure such as the ribs 58 in the front member 30 located on the front side of the handle 10, the occurrence of sink marks and the like in the front member 30 is suppressed. For this reason, the design of the handle 10 can be improved.

[0066] As in this embodiment, the heat insulation door 4 is provided with a handle pedestal 14 formed so as to be recessed from the side surface of the heat insulation door 4 toward the inside. The handle pedestal 14 is provided with a base portion 20 located on the inner side of the heat insulation door 4 and a pedestal protruding portion 26 protruding outward from the heat insulation door 4 from the base portion 20. The front member 30 may be attached to the pedestal protruding portion 26. Thereby, in the storage 1, when the user cleans the storage 1, it becomes easy to clean the connection portion between the handle 10 and the handle pedestal 14. Therefore, in the storage 1, it is possible to suppress the accumulation of dust, dirt, etc. at the connection portion between the handle 10 and the handle pedestal 14.

[0067] As in this embodiment, a smooth curved surface shape with no large angular change is formed at the connection portion between the base portion 20 and the inclined surface portion 22 among the side surfaces of the pedestal protruding portion 26. Thereby, in the storage 1, when the user cleans the storage 1 or the like, it becomes easy to clean the connection portion between the pedestal protruding portion 26 and the base portion 20 and the inclined surface portion 22.
