Description

refrigerator

An embodiment of the invention is directed to a refrigerator.

The heat insulation cabinet as the main body of the refrigerator has an outer case, an inner case, and a heat insulating material (Heat Insulating Materials) provided between the outer case and the inner case. The upper part is roughly formed in a box shape. In recent years, as a heat insulating material for a heat insulating box, there is a heat insulating panel having a high heat insulating property such as a vacuum heat insulating panel. In order to improve the heat insulating performance, such a heat insulating box can make the wall surrounding the heat insulating box thin.

Usually, the heat insulation box of the refrigerator is formed in a rectangular box shape having an opening on the front side and being long in the vertical direction, for example. In this case, the left and right side walls and the rear wall in the wall surrounding the heat insulating box are larger than the other walls, that is, the top wall and the bottom wall. The rear walls of the left and right side walls and the rear wall are connected or integrated with the other walls. On the other hand, the front end portion of the left and right side walls, that is, the opening side end portion is not connected to the other wall in order to form an opening. Therefore, the strength of the opening side of the left and right side walls is slightly smaller than the rear portion. Therefore, the risk of deformation of the left and right side walls is higher than that of the other walls, and when the heat insulating panel is used to make the peripheral wall of the heat insulating box thin, the risk of deformation is further increased.

Thereby, unevenness in thickness of the left and right side wall heat insulating panels 26 and 27 which are generated in the manufacturing process of the left and right side wall heat insulating panels 26 and 27 is allowed to some extent.

In this case, when the thickness dimension of the left and right side wall heat insulating panels 26 and 27 becomes the maximum value of the allowable range, the width dimension Hu of the inside of the heat insulation box 2 becomes a minimum. When the width dimension Hu of the inner side of the heat insulating box 2 is the minimum value, the partition back cover 63 also sets the length dimension of the left and right sides so that the gap G may be generated. However, the gap G is small. In this gap G, it is also possible to fill a heat insulating material such as a soft tape.

That is, the left and right side wall heat insulating panels 26 and 27 are assembled based on the width dimension Hs of the outer side of the heat insulating box 2 shown in FIG. In this case, the thickness unevenness of the left and right side wall heat insulating panels 26 and 27 is absorbed by changing the width dimension Hu of the inner side of the heat insulating box 2. In order to correspond to the change in the width dimension Hu of the inner side of the heat insulating box 2, the bolt insertion hole portion 41e is formed as a long hole which is larger than the diameter of the bolt 72 and which is long in the left-right direction.

The refrigerating chamber floor 8 is disposed such that the engaging projection is fitted into the arrangement hole portion 41d from above the refrigerating chamber bottom plate mounting member 41. In this case, the relatively heavy weight compressor 36 is disposed near the rear of the heat insulation box 2. On the other hand, the bridge-shaped reinforcing member 71 is provided near the front portion of the heat insulating box 2. Therefore, the bridge-shaped reinforcing member 71 contributes to the uniformity of the weights of the front and rear of the heat insulating box 2.

As shown in Fig. 21, a rail 45 is attached to the first rail mounting member 42. The rail 45 extends in the front-rear direction, and guides the movement of the support frame (not shown) attached to the back side of the door 19 of the vegetable compartment 4 in the front-rear direction. The rail 45 is fixed by screwing a bolt to the bolt screwing hole portion 42e formed in the protruding portion 42a of the first rail mounting portion 42. The partition wall mounting member 43 serves as a reinforcing member attaching portion, and as shown in FIG. 3, in the vicinity of the heat insulating partition wall 9, in this case, the lower side of the heat insulating partition wall 9, in the front-rear direction Extended form settings. The partition wall mounting member 43 will be described with reference to Figs. 22 and 23 . The partition wall attachment member 43 is configured in the same manner as the refrigerator compartment floor attachment member 41. In other words, the partition wall attachment member 43 is formed, for example, from a metal plate as a whole, and has an elongated shape extending in the front-rear direction. The partition wall mounting member 43 has a protruding portion 43a, an extending portion 43b, and an engaging portion 43c. The protruding portion 43a, the extending portion 43b, and the engaging portion 43c are integrally formed by, for example, bending a metal plate.

The extending portion 43b is substantially perpendicular to the inner panel 31B, and is formed in a rectangular plate shape that is long in the front-rear direction. The protruding portion 43a is formed by substantially horizontally bending the upper edge portion of the extending portion 43b toward the inside of the reservoir. The engaging portion 43c is formed such that the lower edge portion of the extending portion 43b is bent substantially horizontally toward the inside of the reservoir, and the end portion of the inside of the magazine is bent substantially vertically downward. In this case, the longitudinal section of the protruding portion 43a toward the extending portion 43b is formed in an L shape. In other words, the protruding portion 43a and the extending portion 43b are continuous in such a manner that their longitudinal cross sections are L-shaped. Moreover, the longitudinal cross section of the partition wall mounting member 43 has a groove shape which is open to the inside of the interior as a whole.

A plurality of arrangement hole portions 43d are formed in the protruding portion 43a. Configuration hole The portion 43d is a slit-shaped connecting hole portion along the longitudinal direction of the protruding portion 43a, that is, a slit-shaped connecting hole portion that extends in the front-rear direction. Further, hole portions 31i and 31j are formed in the inner plate 31B. The hole portions 31i and 31j are formed in a slit shape. In the hole portion 31i, the protruding portion 43a is inserted from the back side of the inner panel 31B. In the hole portion 31j, the engaging portion 43c is inserted from the back side of the inner panel 31B. Further, the extending portion 43b of the partition wall mounting member 43 is sandwiched between the back surface of the inner panel 31B and the vacuum heat insulating panel 32, and then is attached to the vacuum heat insulating panel 32 on the back surface of the inner panel 31B. In this case, the engaging portion 43c of the partition wall mounting member 43 is engaged with the hole portion 31j. Thereby, the attachment strength of the partition wall attachment member 43 with respect to the left side wall heat insulation panel 26 is improved.

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

Similarly to the partition back cover 63, the left and right lengths of the heat insulating partition wall 9 are set to have a length dimension in which the gap G is generated in consideration of the unevenness of the thickness of the left side wall heat insulating panel 26 and the right side wall heat insulating panel 27. Moreover, for the same reason, the left-right direction of the arrangement hole portion 43d is set so as to be slightly larger than the outer diameter dimension of the protrusion portion 9c of the heat insulating partition wall 9 in the left-right direction. Inner diameter size. Thereby, the heat insulating partition wall 9 can be adjusted with respect to the joint position of the partition wall mounting member 43.

As shown in FIG. 3, the second rail attachment member 44 is provided on the left and right sides of the main freezing compartment 7, and two are provided in the front-rear direction. The second rail mounting member 44 has the same configuration as the first rail mounting member 42 described above, and is attached to the inner panel 31B in the same manner. Further, in the gap G, a heat insulating material such as a soft tape may be appropriately packed.

In this case, the heat insulating box 2 has a vacuum heat insulating panel 32 as a heat insulating material between the outer panels 30A to 30E constituting the outer surface of the reservoir and the inner panels 31A to 31E constituting the inner surface of the reservoir. The vacuum insulation panel 32 has a higher thermal insulation performance than the foamed urethane 33. Therefore, the heat insulation box 2 can set the wall around it to be thin.

Here, in the heat insulating box of the ordinary refrigerator, there is a case where the edge portion on the opening side of the left and right side walls is less likely to be weaker than the other portions, and is relatively easily deformed by application of an external force. Further, in the heat insulating box 2 in which the thickness of the peripheral wall is reduced by using the vacuum heat insulating panel 32, there is a concern that it is easy to generate the heat insulating panels 26 and 27 applied to the left and right side walls. The influence of the external force on the open end of the surface. In this case, there is a concern that, for example, when the load of the revolving doors 15 and 16 is applied to the end portion on the opening side of the front surface of the heat insulating panels 26 and 27 on the left and right side walls, the left and right side walls are separated by the load. The thermal panels 26, 27 are deformed.

Therefore, the heat insulation box 2 of this embodiment has the longitudinal reinforcement member 51. The longitudinal reinforcing members 51 are respectively disposed on the left side wall heat insulating panel as the left side wall 26. The front surface opening edge portion of the heat insulating panel 27 for the right side wall of the right side wall. According to this, the strength of the heat insulating panels 26 and 27 of the left and right side walls of the heat insulating box 2 is enhanced. Therefore, when an external force is applied to the end portions on the opening side of the front surfaces of the heat insulating panels 26 and 27 for the left and right side walls, the deformation of the heat insulating panels 26 and 27 for the left and right side walls can be suppressed.

The refrigerating chamber bottom plate mounting member 41 and the bridge-shaped reinforcing member 71 suppress the deformation of the left and right side wall heat insulating panels 26 and 27 with respect to the bending direction, and are the thickness dimensions of the left and right side wall heat insulating panels 26 and 27. It is particularly effective in the case of less than or equal to 35 mm. In the present embodiment, the vacuum heat insulating panel 32 has a thickness of 20 mm, and the total thickness of the outer panel 30B and the inner panel 31B is 1.5 mm. Therefore, the thickness of the entire left and right side wall heat insulating panels 26 and 27 is 21.5 mm, and is further effectively a thickness of 25 mm or less.

The left side wall heat insulating panel 26 has a bending portion 30b. The flexure portion 30b is formed by bending the distal end portion of the heat insulating box 2 of the outer panel 30B, which is an end portion on the opening side, toward the inside of the reservoir, and bending the distal end toward the rear side. The longitudinal reinforcing member 51 is provided along the inner side of the flexure portion 30b, that is, the surface on the side of the vacuum heat insulating panel 32. In this case, in addition to the longitudinal reinforcing member 51, the flexure portion 30b contributes to the improvement of the strength of the front end portion of the left side wall heat insulating panel 26. Therefore, the left side wall heat insulating panel 26 is further reinforced, whereby the deformation due to the external force is further suppressed. The heat insulating panel 27 for the right side wall is also the same as the heat insulating panel 26 for the left side wall.

In the left-wall heat insulating panel 26, the longitudinal reinforcing members 51 are not coupled to the inner panel 31B. That is, the longitudinal reinforcing member 51 is formed with respect to the inner panel 31B. Unlinked status. Here, the longitudinal reinforcing member 51 is relatively strong with respect to an external force. Therefore, for example, when the outer panel 30B and the inner panel 31B are connected by the longitudinal reinforcing member 51, the outer panel 30B and the inner panel 31B are controlled by the longitudinal reinforcing member 51 to the thickness direction of the vacuum heat insulating panel 32, that is, the outer panel. The movement of 30B in the direction away from the inner panel 31B. In this case, even if unevenness occurs in the thickness dimension of the vacuum heat insulating panel 32 at the time of manufacture of the vacuum heat insulating panel 32, the distance between the outer panel 30B and the inner panel 31B cannot follow the vacuum heat insulating panel 32. Uneven thickness dimensions. Then, there is a case where an excessive force is applied to the outer plate 30B and the inner plate 31B, and as a result, the outer plate 30B or the inner plate 31B is deformed or generated in the outer width dimension Hs of the heat insulating box 2 shown in Fig. 6. error.

Therefore, in the present embodiment, the outer panel 30B and the inner panel 31B are joined to each other through the vacuum heat insulating panel 32, but are joined to each other without passing through the longitudinal reinforcing member 51. In this case, the outer panel 30B and the inner panel 31B allow relative movement in the left-right direction, that is, in the thickness direction of the vacuum heat insulating panel 32 due to a change in the thickness dimension of the vacuum heat insulating panel 32. In other words, when unevenness occurs in the thickness dimension of the vacuum heat insulating panel 32, the outer panel 30B and the inner panel 31B can relatively move in the thickness direction of the vacuum heat insulating panel 32. Therefore, the distance between the outer panel 30B and the inner panel 31B can follow the unevenness of the thickness dimension of the vacuum heat insulating panel 32. Therefore, when unevenness occurs in the thickness dimension of the vacuum heat insulating panel 32, excessive force is also suppressed from acting on the outer panel 30B and the inner panel 31B. As a result, deformation of the outer panel 30B or the inner panel 31B or an error in the outer width dimension Hs of the heat shield box 2 shown in Fig. 6 can be suppressed. For the right side wall insulation panel 27, it is also separated from the left side wall. The thermal panel 26 is the same.

One of the pair of upper and lower hinge members 17a and 17b supporting the revolving door 15 is provided to the left side wall heat insulating panel 26, and the other hinge member 17a is provided to the top wall heat insulating panel 28. Further, a part of the hinge member 17b is fixed to the longitudinal reinforcing member 51. The load due to the weight of the revolving door 15 and the load applied to the hinge member 17 by the operation at the time of opening and closing are large. However, the hinge member 17b is supported by the longitudinal reinforcing member 51 having a relatively strong strength. Therefore, the hinge member 17b suppresses the movement of the mounting position or the inclination of the hinge shaft 17bj by the load. Therefore, the rotation of the revolving door 15 can be maintained in a good state.

Further, since the inclination of the hinge shaft 17bj is suppressed, the tilting of the revolving door 15 is also suppressed. Therefore, excessive force is applied to the front end portion of the heat insulating panel 26 for the left side wall due to the inclination of the revolving door 15. Thereby, deformation of the left side wall heat insulating panel 26 of the hinge member 17b part can be suppressed. Further, the same effect is exerted on the pair of hinge members 18a and 18b that support the revolving door 16. Further, since the other hinge members 17a and 18a are provided at the right and left corners of the heat insulating panel 28 for the top wall, the hinge members 17a and 18a have a relatively strong weight with respect to the weight of the revolving doors 15 and 16. Incidentally, when the storage chamber opened and closed by the revolving door is in the lower portion of the heat insulating box, the other hinge members 17a and 18a may be provided in the heat insulating panel 29 for the bottom wall.

The reinforcing support member 56 is provided on the back side of the longitudinal reinforcing member 51. Further, a part of the hinge member 17b is fixed to the longitudinal reinforcing member 51 via the reinforcing support member 56. That is, the hinge member 17b is supported by the longitudinal reinforcing member 51 and the reinforcing support member 56. Therefore, the hinge member 17b can be suppressed more effectively The mounting position is lowered, or the hinge member 17b is inclined downward. The same applies to the hinge member 18b.
