  Moreover, about the door which covers the opening of a storehouse, the structure which reduces a clearance gap between a door and an opening by providing a rib along the outer peripheral edge part of a door back surface, and arrange | positioning this rib facing the inner surface of an opening is known. ing. In the configuration including the corner cover as described above, the corner cover is disposed so as to cover the inner surface of the opening. For this reason, it has been necessary to avoid a situation where the rib interferes with the corner cover by bringing the rib toward the inside of the door with respect to the surface of the corner cover. However, the gap between the rib and the inner surface of the opening is increased by bringing the rib to the inside of the door, and there is a concern that the heat insulating property of the storage is deteriorated.

  This invention is completed based on the above situations, Comprising: It aims at providing the storage which can make heat insulation higher.

  In order to solve the above-mentioned problems, the storage of the present invention is a box that forms a storage chamber having a square-shaped opening that opens forward, and rotates with respect to the box in a form that covers the opening. A door that can be attached, and a corner cover that covers a corner formed by a first inner surface and a second inner surface that intersect each other among the inner surfaces of the opening, and the door has a rectangular door body. And a door packing that is provided on the rear surface of the door main body and abuts against the front surface of the opening edge of the opening in the box, and the rear surface of the door main body includes the first inner surface, A rib having a first opposing surface arranged opposite to the second inner surface and a second opposing surface arranged opposite to the second inner surface is provided along the extending direction of the door packing. In the place corresponding to the corner cover Characterized in that the cutouts fitted is formed.

  By providing the notch, it is possible to prevent the corner cover and the rib from interfering with each other. As a result, the rib can be disposed closer to the inner surface of the opening, and the gap between the rib and the inner surface of the opening can be further reduced, so that the heat insulation of the storage chamber can be further increased. .

  The door is pivotally attached to the box with an axis extending in the vertical direction as a rotation axis, and the rib includes a pair of longitudinally extending portions extending in the vertical direction. And a pair of laterally extending portions extending along the horizontal direction. The longitudinally extending portion and the laterally extending portion each have a width that decreases toward the storage chamber. The first inner surface extends along the extending direction of the longitudinally extending portion, and the second inner surface extends along the extending direction of the laterally extending portion, and The direction extending portion has the first facing surface, the lateral extending portion has the second facing surface, and an inclination angle of the second facing surface with respect to the second inner surface is The inclination angle of the first opposing surface with respect to the first inner surface is set to a value smaller than the inclination angle. It can be.

  The clearance gap between a 2nd opposing surface and a 2nd inner surface can be made smaller, and the heat insulation of a store room can be made higher. Moreover, since the rotation axis | shaft of a door is a structure along an up-down direction, when closing a door, the 1st opposing surface of a vertical direction extension part approaches with respect to the 1st inner surface extended in an up-down direction. Become. Here, the inclination angle of the first facing surface with respect to the first inner surface is set to a relatively large value. For this reason, when closing a door, the situation where a 1st opposing surface contact | abuts with respect to a 1st inner surface can be suppressed more reliably.

  The door body includes a door panel, a door pack constituting a rear surface of the door body, and a heat insulating material filled in a space surrounded by the door panel and the door pack.

May be provided with a partition wall portion that partitions the internal space of the contact portion.

  When filling the insulating material between the door panel and the door pack, the contact pack presses the peripheral edge of the door pack so that there is no gap between the peripheral edge of the door pack and the peripheral edge of the panel. Like that. By providing the partition wall portion in the abutting portion, the rigidity of the abutting portion can be further increased, and the situation where the abutting portion is deformed when the heat insulating material is filled can be suppressed. As a result, a gap is generated between the peripheral end portion of the door pack and the peripheral end portion of the panel, and the situation in which the heat insulating material leaks to the outside can be more reliably suppressed.

  The door packing includes a hollow packing main body, a protrusion protruding forward from the packing main body, and fitted into a groove formed on the rear surface of the door main body, and the opening. A magnet that is attracted to the front surface of the opening edge portion is accommodated, a magnet accommodating portion that is arranged on the rear side with respect to the packing main body portion, and a pair of connecting portions that connect the packing main body portion and the magnet accommodating portion. One of the pair of connecting portions connects one end of the packing main body portion and the magnet housing portion in the width direction of the door packing, and the other of the pair of connecting portions. The connecting portion connects the other end portions in the width direction of the door packing in the packing main body portion and the magnet housing portion, and the connecting portion includes a front end portion in the magnet housing portion and a front end portion in the packing main body portion. When, Is intended for connecting, after extending rearwardly from the front end of the magnet housing section, it can be made to extend in the form of folding the packing main body portion side.

  Compared with the shape in which the connecting portion is directed directly from the front end portion of the magnet housing portion toward the packing body portion, the magnet housing portion is easily displaced in the direction away from the packing body portion (rear side). As a result, the magnet housing portion can be securely adhered to the front surface of the opening edge portion.

  Moreover, the identification part which can identify the size of the said door shall be provided in the rear surface of the said door main-body part. The size of the door can be easily identified, and a door of a desired size can be easily selected when the door is assembled to the box.

A pair of identification portions 62 (identification symbols) is provided in a shape that is point-symmetric with respect to the center C1 of the door pack 61 (and thus the door main body portion 50). Further, the material of the door pack 61 (ABS in FIG. 7) is described adjacent to the identification unit 62. The number 120 of the identification unit 62 shown in FIG. 7 is a number indicating that the door 16 is a door of a size used for the cooling storage 10 having a width of 1200 mm. It is not limited and can be changed appropriately. Moreover, the identification part 62 should just be the description which is not limited to a number and can understand the size of the door 16. FIG.

  As shown in FIG. 7, the rear surface of the door main body 50 is provided with a rib 63 configured by bulging a part of the door pack 61 rearward. The rib 63 has a rectangular frame shape extending along the outer peripheral end of the door main body 50, and is arranged inside the door packing 70 in a shape along the extending direction of the door packing 70. Specifically, the rib 63 includes a pair of longitudinally extending portions 64 and 64 extending along the vertical direction, and a pair of laterally extending portions 65 and 65 extending along the horizontal direction. As shown in FIG. 11, the longitudinally extending portion 64 has a shape that becomes narrower toward the storage chamber 11. As shown in FIG. 9, the laterally extending portion 65 is connected to the storage chamber 11. The shape becomes narrower as it goes.

  As shown in FIG. 11, the inner surface of the opening 11 </ b> A has a first inner surface 19 </ b> A that extends along the extending direction of the longitudinally extending portion 64. The longitudinally extending portion 64 has a first facing surface 64A that is disposed to face the first inner surface 19A. Further, as shown in FIG. 9, the inner surface of the opening 11 </ b> A has a second inner surface 19 </ b> B extending along the extending direction of the laterally extending portion 65. The laterally extending portion 65 has a second facing surface 65A that is disposed to face the second inner surface 19B. The first inner surface 19A and the second inner surface 19B are two orthogonal planes. The inclination angle D2 of the second opposing surface 65A with respect to the second inner surface 19B is set to a value smaller than the inclination angle D1 of the first opposing surface 64A with respect to the first inner surface 19A.

  As shown in FIG. 8, in the rib 63, a notch 66 is formed at a location corresponding to the corner cover 32. The notch portion 66 is formed at a corner portion of the rib 63 having a rectangular frame shape (a connecting portion between the longitudinally extending portion 64 and the laterally extending portion 65), and is L-shaped following the shape of the corner portion of the rib 63. It has a shape. As shown in FIG. 6, the corner cover 32 is fitted in the notch 66. In FIG. 6, the outlines of the rib 63 (the first opposing surface 64A and the second opposing surface 65A) are indicated by solid lines.

  As shown by a two-dot chain line in FIG. 7, the door packing 70 has a rectangular frame shape and is disposed outside the rib 63. As shown in FIG. 10, the door packing 70 protrudes to the front side (left side in FIG. 10) from the packing main body portion 71 having a hollow shape and the front surface of the door pack 61 (the rear surface of the door main body portion 50). ) And a magnet 73 that is attracted to the front surface 11B of the opening edge of the opening 11A, and is arranged on the rear side with respect to the packing main body 71. The housing portion 74, and a pair of connecting portions 75 and 76 that connect the packing main body portion 71 and the magnet housing portion 74 are provided. The protrusion 72 has an arrow-bottom shape when viewed in cross section and is configured to be engaged with the inner surface of the groove 67.

  A part of the packing main body 71 is hollow, and serves as an abutting portion 77 that abuts against the peripheral end portion 61 </ b> A of the door pack 61 from the rear side. The abutting portion 77 has a rectangular frame shape in sectional view, and the abutting portion 77 is provided with a partition wall portion 78 that partitions the internal space of the abutting portion 77. The partition wall portion 78 is configured to connect a pair of wall portions opposed to each other in the front-rear direction among the wall portions constituting the contact portion 77. The packing main body 71 has a rectangular shape in cross-section having three internal spaces, and the contact portion 77 constitutes two of the internal spaces.

  When manufacturing the door main body 50, the door panel 51 and the door pack 61 are held by a foaming jig (not shown), and the liquid heat insulating material 54 is injected into the space S1 surrounded by the door panel 51 and the door pack 61. By foaming and solidifying, the heat insulating material 54 is filled. When filling the heat insulating material 54, the door packing 70 is pressed toward the door pack 61 by the foaming jig, and the contact portion 77 is pressed against the peripheral end portion 61 </ b> A of the door pack 61. Thereby, the clearance gap between 61 A of peripheral edge parts and the panel peripheral edge part 53 arises, and the situation where the heat insulating material 54 leaks from the clearance gap can be prevented.

  The connection part 75 (one connection part) shall connect the end parts of the width direction (up-down direction in FIG. 9, FIG. 10) of the door packing 70 in the packing main-body part 71 and the magnet accommodating part 74. The connecting portion 76 (the other connecting portion) connects the other end portions in the width direction of the door packing 70 in the packing main body portion 71 and the magnet housing portion 74. The connecting portion 75 connects the front end portion of the magnet housing portion 74 and the front end portion of the packing main body portion 71, and extends rearward (right side in FIGS. 9 and 10) from the front end portion of the magnet housing portion 74. After that, it extends so as to be folded back to the packing main body 71 side. The connecting portion 76 has a substantially curved shape in cross-section when connecting the front end portion in the magnet housing portion 74 and the front end portion in the packing main body portion 71, and extends rearward from the front end portion in the magnet housing portion 74. It extends in the form of being folded back to the packing main body 71 side.

  The pair of connecting portions 75 and 76 have flexibility, and the magnet housing portion 74 can be displaced in the front-rear direction with respect to the packing main body portion 71. As a result, the magnet 73 is attracted to the front surface 11B (the surface of the metal outer box 12A) of the opening portion 11A, so that the front surface 11B of the opening portion 11A and the magnet housing portion 74 are shown in FIG. And can be closely attached. 9 shows the packing main body 71 and the magnet housing part 74 in the natural state, and the magnet housing part 74 is separated from the front surface of the opening 11A in the natural state. In FIG. 10, the magnet housing portion 74 in the natural state is illustrated by a two-dot chain line. By enabling the magnet housing portion 74 to be displaced in the front-rear direction with respect to the packing main body portion 71, the front surface 11B can be displaced from the predetermined position due to a manufacturing error or the like. The magnet accommodating part 74 can be reliably stuck with respect to 11B. Further, the rear end portion of the magnet housing portion 74 and the front end portion of the packing main body portion 71 are connected by a connecting portion 79 provided so as to cover the connecting portion 76, and the rib 63 is connected to the connecting portion 79. A fin portion 79 </ b> A is provided in contact with the side surface of the plate.

  Next, the effect of this embodiment will be described. In the present embodiment, since the rib 63 includes the notch portion 66, it is possible to prevent the corner cover 32 and the rib 63 from interfering with each other. As a result, the rib 63 can be disposed closer to the inner surface (the first inner surface 19A or the second inner surface 19B) of the opening 11A, and the gap between the rib 63 and the inner surface of the opening 11A can be further reduced. Since it can do, the heat insulation of the storage chamber 11 can be made higher. In addition, when it does not have the notch part 66, it is necessary to distribute | arrange the outer surface 63A of the rib 63 inside the door 16 rather than the surface 32A of the corner cover 32, as shown by the dashed-two dotted line of FIG. A gap S2 is generated between the outer surface 63A and the inner surface of the opening 11A. In the present embodiment, such a gap S2 can be further reduced.

  The inner surface of the opening 11A has a first inner surface 19A extending along the extending direction of the longitudinally extending portion 64 and a second inner surface 19B extending along the extending direction of the laterally extending portion 65. The inclination angle D2 of the second opposing surface 65A of the laterally extending portion 65 with respect to the second inner surface 19B is smaller than the inclination angle D1 of the first opposing surface 64A of the longitudinally extending portion 64 with respect to the first inner surface 19A. It is set by value. By bringing the second facing surface 65A and the second inner surface 19B closer to each other in parallel, the gap between the second facing surface 65A and the second inner surface 19B can be made smaller, and the heat insulation of the storage chamber 11 can be further enhanced. can do. Moreover, since the rotation axis | shaft of the door 16 is a structure along an up-down direction, when closing the door 16, with respect to the 1st inner surface 19A extended in an up-down direction, 64 A of 1st opposing surfaces of the vertical extension part 64 are provided. Will approach. Here, the inclination angle D1 of the first facing surface 64A with respect to the first inner surface 19A is set to a relatively large value. For this reason, when closing the door 16, the situation where the first facing surface 64A abuts against the first inner surface 19A can be more reliably suppressed.

  The door packing 70 is hollow and includes a contact portion 77 that comes into contact with the peripheral end portion 61 </ b> A of the door pack 61 from the rear side. The contact portion 77 has an internal space of the contact portion 77. A partition wall portion 78 is provided for partitioning. When the insulating material 54 is filled between the door panel 51 and the door pack 61, the peripheral end 61 </ b> A of the door pack 61 is pressed by the contact portion 77, and the peripheral end 61 </ b> A of the door pack 61 and the panel of the door panel 51 are pressed. A gap is not generated between the peripheral end portion 53 and the peripheral end portion 53. By providing the partition wall portion 78 in the contact portion 77, the rigidity of the contact portion 77 can be further increased, and a situation in which the contact portion 77 is deformed when the heat insulating material 54 is filled can be suppressed. As a result, a gap is generated between the peripheral end portion 61A of the door pack 61 and the panel peripheral end portion 53, and the situation where the heat insulating material 54 leaks to the outside can be more reliably suppressed.

  The door packing 70 includes a pair of connecting portions 75 and 76 that connect the packing main body portion 71 and the magnet housing portion 74, and the pair of connecting portions 75 and 76 includes the packing main body portion 71 and the magnet housing portion 74. The both ends of the door packing 70 in the width direction are connected to each other, and the connecting portion 75 has a curved shape that connects the front end portion of the magnet housing portion 74 and the front end portion of the packing main body portion 71. After extending rearward from the front end portion of the magnet housing portion 74, the magnet housing portion 74 extends so as to be folded back toward the packing main body portion 71 side. Compared with the shape in which the coupling portions 75 and 76 are directed directly from the front end portion of the magnet housing portion 74 toward the packing body portion 71, the magnet housing portion 74 is easily displaced in the direction away from the packing body portion 71 (rear side). . As a result, the magnet accommodating portion 74 can be reliably adhered to the front surface 11B of the opening edge portion of the opening 11A.

  Moreover, the connection part 76 has the circular arc part 76A which makes circular arc shape in the natural state shown in FIG. The connecting portion 76 is configured to connect the front end portion of the magnet housing portion 74 and the front end portion of the packing main body portion 71. For this reason, compared with the structure which connects the connection part 76 with the front-end part in the magnet accommodating part 74, and the rear-end part in the packing main-body part 71, the curvature radius of 76 A of circular arc parts can be enlarged. As a result, the magnet accommodating portion 74 can be displaced more easily by making the connecting portion 76 more flexible and deformable.

  An identification unit 62 that can identify the size of the door 16 is provided on the rear surface of the door main body 50. The size of the door 16 can be easily identified, and the door 16 having a desired size can be easily selected when the door 16 is assembled to the box 12.
