Description

refrigerator

Embodiment of this invention is related with a refrigerator.

The heat insulation cabinet which is the main body of the refrigerator has an outer box, an inner box, and a heat insulating material provided between the outer box and the inner box, and is configured in a substantially box shape as a whole. In recent years, as a heat insulating material for a heat insulating cabinet, there is one using a heat insulating panel having high heat insulating performance such as a vacuum heat insulating panel. In such a heat insulation cabinet, since the heat insulation performance is improved, the surrounding wall constituting the heat insulation cabinet can be thinned.

Generally, a heat insulation cabinet of a refrigerator has an opening on the front side, and is formed in a rectangular box shape that is long in the vertical direction, for example. In this case, among the surrounding walls constituting the heat insulation cabinet, the left and right side walls and the rear wall are larger than the other walls, that is, the ceiling wall and the bottom wall. Among these left and right side walls and the rear wall, the rear wall is connected to or integrated with the other walls. On the other hand, the left and right side walls are not connected to other walls at their front portions, that is, the end portions on the opening side to form openings. For this reason, the opening side of the left and right side walls is slightly inferior to the rear part. Therefore, the left and right side walls are more likely to be deformed than the other walls, and when the peripheral wall of the heat insulation cabinet is thinned using a heat insulation panel, the risk of deformation is further increased.

That is, the left side wall heat insulation panel 26 and the right side wall heat insulation panel 27 are assembled on the basis of the width dimension Hs outside the heat insulation cabinet 2 shown in FIG. In this case, the variation in the thickness dimension generated in the left-side wall heat insulation panel 26 and the right-side wall heat insulation panel 27 is absorbed by changing the width dimension Hu inside the heat insulation cabinet 2. Thereby, the variation in the thickness dimension of the right and left side heat insulating panels 26 and 27 that occurs in the manufacturing process of the left and right side heat insulating panels 26 and 27 is allowed to some extent.

In this case, when the thickness dimension of the heat insulation panels 26 and 27 for the left and right side walls becomes the maximum value in the allowable range, the width dimension Hu inside the heat insulation cabinet 2 becomes the minimum value. The left and right length dimensions of the partition back cover 63 are set so that the gap G is generated even when the inner width dimension Hu of the heat insulating cabinet 2 is the minimum value. However, this gap G is slight. The gap G may be filled with a heat insulating material such as soft tape.

In this case, the screw insertion hole 41e is formed of a long hole that is long in the left-right direction. Therefore, the connecting position of the bridge-shaped reinforcing member 71 can be adjusted with respect to the left and right refrigerator compartment bottom plate attachment members 41. Therefore, the bridge-shaped reinforcing member 71 can be satisfactorily attached to the left and right refrigerator compartment bottom plate attachment members 41 even if the thickness dimensions of the left and right side heat insulating panels 26 and 27 vary.

That is, the heat insulation panels 26 and 27 for the left and right side walls are assembled on the basis of the width dimension Hs outside the heat insulation cabinet 2 shown in FIG. In this case, the variation in the thickness dimension of the left and right side heat insulating panels 26 and 27 is absorbed by changing the inner width dimension Hu of the heat insulating cabinet 2. The screw insertion hole 41e is formed as a long hole that is larger than the diameter of the screw 72 and long in the left-right direction in order to cope with a change in the width dimension Hu inside the heat insulating cabinet 2.

FIG. The bridge-shaped reinforcing member 71 is firmly connected to the refrigerator compartment bottom plate attachment member 41 by screws 72 after the attachment positions of the left and right refrigerator compartment bottom plate attachment members 41 and 41 are adjusted. For this reason, it can suppress effectively that the heat insulation panels 26 and 27 for right and left side walls deform | transform into a curve direction.

The protruding part 42a protrudes inward from the inner plate 31B and is formed in a substantially cylindrical shape with the bottom on the inner side closed. In this case, the protrusion 42a is formed in a cylindrical shape close to a bowl shape.

The extending part 42b is formed in a plate shape extending in the vertical direction around the skirt of the protruding part 42a. One upper engaging portion 42c is provided at the center of the extending portion 42b in the front-rear direction at the upper portion of the extending portion 42b. The upper engaging portion 42c protrudes upward in an L shape. That is, the upper engaging portion 42c is bent so as to protrude from the upper end portion of the extending portion 42b to the inside of the warehouse, and the protruding tip portion is bent upward. Two lower engaging portions 42d are provided in the lower part of the extending portion 42b and in the front-rear direction of the extending portion 42b. The lower engaging portion 42d is bent so as to protrude from the lower end portion of the extending portion 42b to the inside of the warehouse. A screw screw hole 42e is formed in the protruding portion 42a.

The upper engagement hole 31g and the lower engagement hole 31h are formed through the inner plate 31B in a slit shape that is long in the front-rear direction. The upper engagement hole 31g is formed at one place above the hole 31f. The lower engagement hole 31h is formed below the hole 31f and at two locations in the front-rear direction.

In this case, the attachment of the first rail attachment member 42 to the inner plate 31B is performed as follows. First, the upper engaging portion 42c of the first rail mounting member 42 is inserted into the upper engaging hole portion 31g from the back surface side of the inner plate 31B. And while rotating the 1st rail attachment member 42 to the inner-plate 31B side centering | focusing on the upper side engaging part 42c, while inserting the protrusion part 42a in the hole 31f, the lower side engaging part 42d is made lower side Insert into the engaging hole 31h. At this time, an adhesive is applied between the extending portion 42b and the back surface of the inner plate 31B, whereby the extending portion 42b is bonded to the back surface of the inner plate 31B. The extending part 42b is also bonded to the vacuum heat insulating panel 32 with an adhesive or the like. Thus, the extending part 42b is fixed to the inner plate 31B and the vacuum heat insulation panel 32 by adhesion in a state sandwiched between the inner plate 31B and the vacuum heat insulation panel 32.

21. A rail 45 is attached to the first rail attachment member 42 as shown in FIG. The rail 45 extends in the front-rear direction, and guides the movement in the front-rear direction of a support frame (not shown) attached to the back side of the door 19 of the vegetable compartment 4. The rail 45 is fixed by screwing a screw into a screw screw hole 42e formed in the protrusion 42a of the first rail mounting member 42. The partition wall mounting member 43 also serves as a reinforcing member mounting portion, and as shown in FIG. 3, in the vicinity of the heat insulating partition wall 9, in this case, below the heat insulating partition wall 9 and extending in the front-rear direction. Is provided. The partition wall mounting member 43 will be described with reference to FIGS. 22 and 23. The partition wall mounting member 43 is configured similarly to the refrigerator compartment bottom plate mounting member 41. That is, the partition wall attachment member 43 is formed in a long shape extending in the front-rear direction as a whole from, for example, a metal plate. The partition wall mounting member 43 includes a protruding portion 43a, an extending portion 43b, and an engaging portion 43c. The projecting portion 43a, the extending portion 43b, and the engaging portion 43c are integrally formed, for example, by bending a metal plate.

The extending portion 43b is formed in a rectangular plate shape that is parallel to the inner plate 31B, that is, substantially perpendicular and long in the front-rear direction. The protruding portion 43a is formed by being bent substantially horizontally from the upper edge portion of the extending portion 43b to the inside of the warehouse. The engaging portion 43c is formed by being bent substantially horizontally from the lower edge portion of the extending portion 43b toward the inside of the cabinet, and further, the end portion inside the cabinet is bent substantially vertically downward. In this case, the longitudinal section from the protruding portion 43a to the extending portion 43b is formed in an L shape. That is, the projecting portion 43a and the extending portion 43b are continuous so that the longitudinal section thereof is L-shaped. Further, the vertical cross section of the partition wall mounting member 43 has a groove shape in which the inner side is opened as a whole.

A plurality of arrangement holes 43d are formed in the protrusion 43a. The arrangement hole 43d is a slit-like connection hole extending in the longitudinal direction of the protrusion 43a, that is, extending in the front-rear direction. Further, holes 31i and 31j are formed in the inner plate 31B. The holes 31i and 31j are formed in a slit shape. A protrusion 43a is inserted into the hole 31i from the back side of the inner plate 31B. The engaging portion 43c is inserted into the hole portion 31j from the back side of the inner plate 31B. The extending portion 43 b of the partition wall mounting member 43 is bonded to the back surface of the inner plate 31 </ b> B and the vacuum heat insulation panel 32 while being sandwiched between the back surface of the inner plate 31 </ b> B and the vacuum heat insulation panel 32. In this case, in the partition wall mounting member 43, the engaging portion 43c and the hole portion 31j are engaged. Thereby, the attachment strength with respect to the heat insulation panel 26 for left side walls of the attachment member 43 for partition walls improves.

As shown in FIG. 23, the heat insulating partition wall 9 has a heat insulating material 9b such as urethane foam inside the outer casing portion 9a. A protruding portion 9c is formed integrally with the outer casing portion 9a. The protruding portion 9c is formed in a cylindrical shape that protrudes downward from the lower side surfaces of the left and right ends of the outer casing portion 9a. In FIG. 23, only the protrusion 9c at the left end is shown. The protrusion 9c is inserted into and engaged with the arrangement hole 43d of the partition wall attachment member 43 attached to the left and right side heat insulating panels 26 and 27. Thereby, the heat insulation partition wall 9 is provided in the heat insulation cabinet 2 so that the inside of the heat insulation cabinet 2 may be divided up and down. In this case, the heat insulating partition wall 9 also serves as a bridge-shaped reinforcing member.

The left and right lengths of the heat insulating partition wall 9 are set to lengths in which the gap G is generated in consideration of variations in the thickness dimensions of the left side wall heat insulating panel 26 and the right side wall heat insulating panel 27 in the same manner as the partition back cover 63. Has been. For the same reason, the inner diameter dimension in the left-right direction of the arrangement hole 43d is set to be slightly larger than the outer diameter dimension in the left-right direction of the protrusion 9c of the heat insulating partition wall 9. Thereby, the heat insulation partition wall 9 can adjust the connection position with respect to the partition wall attachment member 43.

As shown in FIG. 3, two second rail mounting members 44 are provided on the left and right sides of the main freezer compartment 7 in the front-rear direction. The second rail mounting member 44 has the same configuration as the first rail mounting member 42, and is similarly mounted on the inner plate 31B. Note that the gap G may be appropriately filled with a heat insulating material such as soft tape.

According to this, the heat insulating cabinet 2 has the vacuum heat insulating panel 32 as a heat insulating material between the outer plates 30A to 30E constituting the outer surface of the cabinet and the inner plates 31A to 31E constituting the inner surface. is doing. The vacuum heat insulation panel 32 has higher heat insulation performance than the urethane foam 33. Therefore, the heat insulation cabinet 2 can make the surrounding wall thin.

Here, in a general refrigerator heat insulation cabinet, the edges on the opening side of the left and right side walls tend to be weaker than other parts, and may be relatively easily deformed by the application of external force. And in the heat insulation cabinet 2 which aimed at thickness reduction of the surrounding wall using the vacuum heat insulation panel 32 like this embodiment, the influence of the external force added to the edge part by the side of the opening of the heat insulation panels 26 and 27 for right and left side walls is received. There is a risk that it will be larger. In this case, for example, if a load such as the rotary doors 15 and 16 is applied to the end of the front side of the heat insulating panels 26 and 27 for the left and right side walls, the right and left side heat insulating panels 26 and 27 may be deformed by the load. is there.

Therefore, the heat insulating cabinet 2 of the present embodiment has a vertical reinforcing member 51. The vertical reinforcing members 51 are provided at the front opening edge portions of the left side wall heat insulation panel 26 that is the left side wall and the right side wall heat insulation panel 27 that is the right side wall. According to this, the intensity | strength of the heat insulation panels 26 and 27 for right and left side walls of the heat insulation cabinet 2 is strengthened. Therefore, even when an external force is applied to the opening side end portions of the front surfaces of the left and right side wall heat insulation panels 26 and 27, deformation of the left and right side wall heat insulation panels 26 and 27 can be suppressed.

The deformation of the left and right side wall heat insulation panels 26 and 27 in the bending direction by the cold room bottom plate mounting member 41 and the bridge-shaped reinforcing member 71 is suppressed when the thickness dimension of the left and right side wall heat insulation panels 26 and 27 is 35 mm or less. It is particularly effective. In the present embodiment, the vacuum heat insulation panel 32 has a thickness dimension of 20 mm, and the total thickness dimension of the outer plate 30B and the inner plate 31B is 1.5 mm. Therefore, the overall thickness dimension of the left and right side heat insulating panels 26 and 27 is 21.5 mm, which is an effective thickness dimension of 25 mm or less.

The left-side wall heat insulation panel 26 has a bent portion 30b. The bent portion 30b is formed by bending an end portion on the opening side of the heat insulating cabinet 2 in the outer plate 30B, that is, a front end portion to the inside of the cabinet, and further bending the tip thereof to the rear side. The longitudinal reinforcing member 51 is provided along the inner surface of the bent portion 30b, that is, the surface on the vacuum heat insulating panel 32 side. According to this, in addition to the longitudinal reinforcing member 51, the bent portion 30b also contributes to the improvement of the strength of the front end portion of the left-side wall heat insulation panel 26. Therefore, the left-side wall heat insulation panel 26 is further strengthened, and thereby deformation due to external force is further suppressed. The heat insulation panel 27 for the right side wall is the same as the heat insulation panel 26 for the left side wall.

In the left side wall heat insulating panel 26, the vertical reinforcing member 51 is not connected to the inner plate 31B. That is, the vertical reinforcing member 51 is not connected to the inner plate 31B. Here, the longitudinal reinforcing member 51 is relatively strong against external force. Therefore, for example, when the outer plate 30B and the inner plate 31B are connected by the vertical reinforcing member 51, the outer plate 30B and the inner plate 31B are connected by the vertical reinforcing member 51 in the thickness direction of the vacuum heat insulating panel 32, that is, the outer plate 30B. Movement in the direction in which the plate 30B and the inner plate 31B are separated is restricted. In this case, even when the thickness of the vacuum insulation panel 32 varies during the manufacture of the vacuum insulation panel 32, the distance between the outer plate 30B and the inner plate 31B follows the variation of the thickness of the vacuum insulation panel 32. Can not. Then, an excessive force may act on the outer plate 30B and the inner plate 31B. As a result, the outer plate 30B and the inner plate 31B are deformed, or an error occurs in the outer width dimension Hs of the heat insulating cabinet 2 shown in FIG. May occur.

Therefore, in the present embodiment, the outer plate 30B and the inner plate 31B are joined to each other via the vacuum heat insulating panel 32, but are not joined to each other via the longitudinal reinforcing member 51. Accordingly, the outer plate 30B and the inner plate 31B are allowed to move relative to each other in the left-right direction, that is, in the thickness direction of the vacuum heat insulation panel 32 due to the change in the thickness dimension of the vacuum heat insulation panel 32. That is, when the thickness dimension of the vacuum heat insulation panel 32 varies, the outer plate 30 </ b> B and the inner plate 31 </ b> B can move relatively in the thickness direction of the vacuum heat insulation panel 32. Therefore, the distance between the outer plate 30B and the inner plate 31B can follow the variation in the thickness dimension of the vacuum heat insulating panel 32. Therefore, even when the thickness dimension of the vacuum heat insulation panel 32 varies, it is possible to suppress an excessive force from acting on the outer plate 30B and the inner plate 31B. As a result, it is possible to prevent the outer plate 30B and the inner plate 31B from being deformed and an error from occurring in the outer width dimension Hs of the heat insulating cabinet 2 shown in FIG. The heat insulation panel 27 for the right side wall is the same as the heat insulation panel 26 for the left side wall.

Of the pair of upper and lower hinge members 17a, 17b that support the revolving door 15, one hinge member 17b is provided on the left-side wall heat insulation panel 26, and the other hinge member 17a is provided on the ceiling wall heat insulation panel 28. . A part of the one hinge member 17 b is fixed to the vertical reinforcing member 51. The load applied to the hinge member 17 due to the load due to the weight of the rotary door 15 and the operation during opening and closing is large. However, the hinge member 17b is supported by the longitudinal reinforcing member 51 having relatively high strength. Therefore, the hinge member 17b is restrained from moving the attachment position or tilting the hinge shaft 17bj due to the load. Therefore, the rotation of the rotary door 15 can be maintained in a good state.

Further, since the tilt of the hinge shaft 17bj is suppressed, the tilt of the rotary door 15 is also suppressed. Accordingly, it is possible to prevent an excessive force from being applied to the front end portion of the left-side wall heat insulation panel 26 due to the tilt of the rotary door 15. Thereby, the deformation | transformation of the left side wall heat insulation panel 26 in the hinge member 17b part can be suppressed. The same effect can be obtained with the pair of hinge members 18a and 18b that support the rotary door 16. Further, the other hinge members 17a and 18a are provided at the left and right corner portions of the ceiling wall heat insulation panel 28, so that they have a relatively strong structure against the load caused by the rotary doors 15 and 16. Incidentally, when the storage room opened and closed by the revolving door is at the lower part of the heat insulation cabinet, the other hinge members 17a and 18a may be provided on the heat insulation panel 29 for the bottom wall.

The reinforcing contact member 56 is provided on the back side of the vertical reinforcing member 51. A part of the hinge member 17 b is fixed to the vertical reinforcing member 51 via the reinforcing contact member 56.
