FIG. 1 is a front view of the refrigerator 100 according to the first embodiment. FIG. 2 is a perspective view of the refrigerator 100 according to Embodiment 1 as viewed from above. FIG. 3 is an exploded perspective view of the upper part of the refrigerator 100 according to Embodiment 1 as viewed from above. FIG. 4 is an enlarged side view of the upper part of the refrigerator 100 according to the first embodiment. Figure 5 is a cross-sectional view taken along arrow A-A in Figure 4 . Figure 6 is an enlarged view of part B in Figure 5.

Here, the positional relationship between the components of the refrigerator 100 described below, such as up and down, left and right, front and rear, outside and inside, front and back, or vertical and horizontal, basically refers to the positional relationship when the refrigerator 100 is installed in a usable state. In addition, the dimensional relationship and shape of each member in the following figures including Figures 1 to 6 may differ from the actual product. In addition, in the following figures, the same members or parts or members or parts having the same functions are given the same symbols, or the symbols are omitted.

As shown in FIGS. 1 and 2 , the refrigerator 100 has a box 1 with a front opening (not shown), and a plurality of doors 2 covering the front opening of the box 1 . The cabinet 1 and the door 2 form the outer outline of the refrigerator 100 . Here, Embodiment 1 is described as an example of a refrigerator 100 having two doors 2 in which the upper stage is the refrigerator compartment 10a and the lower stage is the freezer compartment 10b. Furthermore, as shown in FIGS. 1 to 3 , the upper surface of the box 1 is provided with a top plate 3 .

The box 1 is a heat-insulating device that can store food and other stored objects inside the box 1 shell. Furthermore, as shown in FIG. 5 , the box 1 includes an outer box 1 b that forms the outer shell of the refrigerator 100 and an inner box 1 a that forms an internal space of the refrigerator 100 . The outer box 1b is formed of a steel plate such as stainless steel. The inner box 1a is made of synthetic resin such as plastic. Furthermore, the space between the outer box 1b and the inner box 1a is filled with a heat insulating material 8 having heat insulating properties such as a vacuum heat insulating material or urethane resin.

Furthermore, the box 1 has one or more heat-insulating partition walls (not shown). The internal space of the inner box 1a is divided into one or more storage rooms (not shown) in different temperature zones by partition walls. The interior of the partition wall is filled with a thermal insulating material (not shown) such as a vacuum insulation material or urethane resin, so that heat conduction does not occur between adjacent storage rooms via the partition wall. For example, when the refrigerator 100 is configured as a double-door freezer-refrigerator, the storage compartment can be used as the freezer compartment 10b and the refrigerator compartment 10a having a different cooling temperature from the freezer compartment 10b.

The door 2 makes the internal space of the box 1 open or closed. The door 2 is mounted on the box 1 to open and close the front opening freely. The decorative surface 2a of the door 2, that is, the front surface and the peripheral surface, are formed of glass or sheet metal. The back side of the door 2 is made of synthetic resin such as plastic. The space between the decorative surface 2a and the back surface of the door 2 is filled with a heat insulating material 8 having heat insulating properties such as a vacuum heat insulating material or urethane resin.

As shown in FIGS. 1 and 2 , the number of doors 2 corresponding to the storage compartments of the refrigerator 100 is provided. For example, when the refrigerator 100 has two storage compartments, the refrigerator 100 is provided with two doors, namely the refrigerator compartment door 21 and the freezer compartment door 22 .

As shown in FIGS. 3 to 6 , the refrigerator compartment door 21 is installed on the box 1 through a hinge 30 . The hinge 30 connects the box body 1 and the refrigerating compartment door 21 and rotates the refrigerating compartment door 21 . Here, for example, when the refrigerator compartment door 21 is a rotary double door having a left door and a right door, the left door and the right door are respectively attached to the upper part of the box 1 through left door hinges and right door hinges. Furthermore, the upper surface of the box 1 is provided with an assembly 5 for fixing the hinge 30 and the top plate 3. The assembly 5 is provided with a fixing device 4 for fixing the top plate 3 .

For most refrigerators with a storage capacity of 200L or less, as shown in FIGS. 1 and 2 , the door 2 of the refrigerator compartment 10a is a single-piece door. As shown in FIG. 3 , the upper surface of the box 1 is provided with a top plate 3 , which covers the upper surface of the box 1 and the hinge 30 of the refrigerator 100 . The top plate 3 is formed of heat-resistant resin, and has a structure that allows the upper surface of the box 1 to be used as a storage space for placing a microwave oven or the like, or as a work space for pouring water into a cup or the like.

Many families place household appliances such as a microwave oven or an electric cooker on the top plate 3 of the refrigerator 100 provided with the top plate 3 . Therefore, when the space on the top plate 3 is small and these household appliances are placed on the top plate 3, other items cannot be placed, or operations such as placing a cup to pour water cannot be performed, and the use is limited. In this regard, the structure of the refrigerator 100 which secures a relatively wide space on the top plate 3 in order to solve this problem is demonstrated using Embodiment 1.

FIG. 7 is a perspective view of the top panel 3 of the refrigerator 100 according to Embodiment 1 as viewed from above. FIG. 8 is a perspective view of the top panel 3 of the refrigerator 100 according to Embodiment 1 as viewed from below. FIG. 9 is a top view and a cross-sectional view of the top plate 3 of the refrigerator 100 according to the first embodiment, as viewed by arrow A-A. FIG. 10 is an upper perspective view of the refrigerator 100 according to Embodiment 1 with the top plate 3 removed, viewed from above. FIG. 11 is a perspective view of the assembly 5 of the refrigerator 100 according to Embodiment 1 as viewed from above.

As shown in FIGS. 7 to 9 , the top plate 3 is formed to have a surface 3 c 1 that covers the upper surface of the cabinet 1 and the upper surface of the door 2 of the refrigerator 100 and forms the upper surface of the refrigerator 100 , and is formed on the door 2 of the refrigerator 100 . The shape of five surfaces in total, including the surface 3c2 that forms the front surface of the refrigerator 100 and the three surfaces 3c3 that cover the upper ends of the right side, left side and rear of the box 1 and extend toward the bottom of the box 1 . Here, the top plate 3 does not need to cover the entire upper surface of the box 1 and the upper surface of the door 2 , but may cover most of the upper surface of the box 1 and most of the upper surface of the door 2 . Here, among the surfaces 3c1 forming the upper surface of the refrigerator 100, the portion covering the upper surface of the door 2 is called an extension portion 3d. In addition, the back surface of the protruding portion 3d of the top plate 3 is provided with a larger first claw portion 3c that spans the entire width of the protruding portion 3d and is several centimeters toward the rear from the front end, and the lower surface of the top plate 3 is located on the left and right respectively. The second claw portion 3a is provided.

The top plate 3 is fixed to the rear surface of the box 1 of the refrigerator 100 by screws. As shown in Figure 6, the second claw portion 3a on the lower surface of the top plate 3 is embedded in the assembly 5 installed on the upper surface of the box 1. The fixing device 4 is used to fix the front side of the top plate 3 . The size of the top panel 3 of a conventional refrigerator is such that it only covers the upper surface of the cabinet. However, the top plate 3 of Embodiment 1 is formed to cover not only the upper surface of the box 1 but also the upper surface of the refrigerator compartment door 21, thereby ensuring a wider and smoother upper surface than in conventional refrigerators. surface, so a wider space can be ensured on the top plate 3.

Furthermore, in order to fix the hinge to the upper surface of the box with screws, conventional refrigerators attach an assembly made of sheet metal to the inside of the upper surface of the outer box that forms the outer shell of the box. On the other hand, in the refrigerator 100 according to Embodiment 1, the assembly part 5 for fixing the hinge 30 to the upper surface of the cabinet 1 with screws is made wider than before, and the assembly part 5 serves as the hinge 30 and the top plate 3 Common fixing sheet metal parts.

As shown in FIG. 11 , the assembly 5 is provided with an L-shaped fixture 4 in side view for fixing the top plate 3 . The fixture 4 is formed by cutting and pulling up a sheet metal piece. It consists of a plate-shaped wall portion 32 that protrudes upward, and a locking device that extends forward from the front end of the wall portion 32 and locks the top plate 3 in the up and down direction. It is composed of stop part 33. As shown in FIG. 6 , the fixture 4 is provided for the assembly 5 that is a sheet metal part so that when the assembly 5 is fixed to the hinge 30 with screws 31 via the outer box 1 b, the fixture 4 protrudes from the hinge 30 side. The fixture 4 is formed on the upper surface of the outer box 1b. The upper surface opening 1 c is configured to protrude toward the upper surface side of the box 1 . In addition, as shown in FIG. 11 , the assembly part 5 is formed with a protrusion 35 protruding upward. When the assembly part 5 is installed from the inside of the outer box 1 b, it fits into the upper surface of the outer box 1 b (not shown). position through the opening (shown). Furthermore, the assembly part 5 is formed with screw holes 34 for fixing the assembly part 5 to the hinge 30 and the outer box 1 b with screws.

As described above, by using the assembly part 5 as a common fixing sheet metal member for the hinge 30 and the top plate 3 , there is no need to prepare a separate assembly part for fixing the top plate 3 to the upper surface of the box 1 . Furthermore, when installing the hinge 30, fix the hinge 30, the outer box 1b and the components 5 with screws, and fill the inside of the box 1 with a thermal insulating material 8 such as vacuum insulation material or urethane resin. The assembly 5 is pushed toward the outer box 1b side by the pressure of the heat insulating material 8 . Thereby, since the assembly part 5 can be stably fixed to the outer box 1b, there is no need to fix the assembly part 5 with screws near the upper surface opening 1c to prevent positional deviation, and the work steps can be simplified.

As shown in FIG. 10 , the fixtures 4 are located in front of the center of the upper surface of the box 1 in the depth direction, and are provided at one place on the left and right respectively. In addition, the second claw portion 3a is fitted into the fixture 4 by sliding the top plate 3 from the front to the rear with respect to the fixture 4. In addition, in a state where the second claw portion 3 a is engaged with the fixture 4 , the top plate 3 is fixed to the rear surface of the box 1 with screws, so that the top plate 3 is fixed to the upper surface of the box 1 . In this way, since the top plate 3 can be fixed to the box 1 only by screws on the rear surface of the box 1, the work steps can be simplified.

Furthermore, as shown in FIG. 7 , the upper surface of the top plate 3 is provided with an edge portion 3 b protruding upward by about 1 mm along the outer circumference. When the edge portion 3b is provided on the top plate 3 in this way, even if the liquid overflows onto the top plate 3 when working on the top plate 3, the edge portion 3b can prevent the liquid from overflowing from the top plate 3 to the floor, etc., and the liquid will not Immersed in the refrigerator 100, thus improving cleaning sex.

As described above, extending the front of the top plate 3 to the upper surface of the door 2 to form an extended shape covering the upper surface of the door 2 can effectively utilize the upper surface space of the refrigerator compartment door 21 . In addition, in order to avoid friction, collision, etc. between the parts constituting the top plate 3 and the refrigerating compartment door 21 when the refrigerating compartment door 21 is opened and closed, the portion of the resin frame constituting the refrigerating compartment door 21 that constitutes the upper surface of the door 2 can be made lower than the top plate. 3 without touching the top plate 3.

FIG. 12 is a perspective view showing the state in which the reinforcing sheet metal 6 is attached to the upper part of the refrigerator 100 according to the first embodiment. FIG. 13 is a longitudinal cross-sectional view in the depth direction when the reinforcing sheet metal 6 is installed on the upper part of the refrigerator 100 according to the first embodiment. FIG. 14 is a perspective view of the reinforcing sheet metal 6 of the refrigerator 100 according to Embodiment 1 as viewed from above. FIG. 15 is a perspective view of the reinforcing sheet metal 6 of the refrigerator 100 according to Embodiment 1 as viewed from below.

When placing items on the top plate 3 or performing work on the top plate 3 , when force is applied to the top plate 3 , the box 1 side can bear the force exerted on the upper surface of the box 1 , thereby preventing parts such as the top plate 3 from being damaged. of deformation. However, the box 1 cannot withstand the force exerted on the protruding portion 3d formed by extending the front of the top plate 3 to the upper surface of the door 2, and since the upper surface of the door 2 is formed lower than the top plate 3, it does not contact the top plate 3 , so door 2 cannot withstand its force. Therefore, when the protruding portion 3d is stressed, the top plate 3 may be deformed. Furthermore, if the top panel 3 is deformed, when the refrigerator compartment door 21 is opened and closed, the deformed top panel 3 may come into contact with the door 2, making it difficult or impossible to open and close the door 2. In order to prevent such a situation, the refrigerator 100 of Embodiment 1 installs a reinforcing sheet metal member 6 between the top plate 3 and the box 1 to increase the strength of the protruding portion 3d.

As shown in FIGS. 12 and 13 , in the refrigerator 100 according to Embodiment 1, when the top panel 3 is installed, the reinforcing sheet metal 6 is installed between the box 1 and the top panel 3 . This reinforcing sheet metal part 6 series is set to It is made of sheet metal with a thickness of 1.0mm, with a strength that can withstand five 2L (liter) bottles, and a thickness that does not deform even when a weight of 10Kg is applied. Here, the thickness of the reinforcing sheet metal member 6 may also be increased according to the magnitude of the assumed force exerted on the top plate 3 .

The reinforcing sheet metal parts 6 are fixed to the upper surface of the box 1 by screws or double-sided tape before the top plate 3 is installed on the box 1 . At this time, the reinforcing sheet metal member 6 is fixed to cover the front upper surface of the box 1 and the upper surface of the door 2 . Here, the reinforcing sheet metal 6 does not need to cover the entire front upper surface of the box 1 and the upper surface of the door 2. It is sufficient if it covers most of the front upper surface of the box 1 and most of the upper surface of the door 2. , when viewed from above, the refrigerator 100 has a shape converging on the inside of the top plate 3 . With such a structure, the strength of not only the side portions of the top plate 3 but also the central portion can be increased, so that deformation of the top plate 3 when a force is applied to the protruding portion 3d can be suppressed. Furthermore, when the top plate 3 is installed on the box 1 , the front end portion of the reinforcing sheet metal 6 has a structure that enters the first claw portion 3 c of the top plate 3 . With such a structure, the top plate 3 and the reinforcing sheet metal 6 can be reliably fitted, so that the force applied to the top plate 3 can be reliably transmitted to the reinforcing sheet metal 6, and deformation of the protruding portion 3d of the top plate 3 can be prevented. Furthermore, since the front end of the reinforcing sheet metal 6 enters the first claw portion 3 c of the top plate 3 , the user can be prevented from touching the front end of the reinforcing sheet metal 6 .

The reinforcing sheet metal 6 must have such strength that the top plate 3 will not bend even when an object is placed on the top plate 3 . When the thickness of the reinforcing sheet metal member 6 itself or the strength provided by the material is insufficient, as shown in FIGS. 14 and 15 , the surface of the reinforcing sheet metal member 6 can be formed into a concave and convex undulating shape 6 a. In this way, the strength of the reinforcing sheet metal 6 can be increased. Even when heavy household appliances such as microwave ovens or electric cookers are placed on the top plate 3, the top plate 3 can be prevented from bending, and the door 2 and the box can also be prevented from being bent. The parts of the body 1 are damaged and the design quality is reduced.

Here, if the claw portion of the extension portion 3d of the top plate 3 is along the width direction, that is, left and right When a plurality of directions are provided and the front end of the reinforcing sheet metal 6 enters a plurality of claws of the top plate 3, the load from the force from above the top plate 3 will be concentrated on a specific claw, easily causing damage. On the other hand, in Embodiment 1, the first claw portion 3c of the protruding portion 3d of the top plate 3 is a large single claw portion provided across the entire width of the protruding portion 3d. The entire surface of the protruding portion 3d can bear the load, so the strength can be further improved.

In addition, as shown in FIG. 13 , the hinge 30 has an inclined surface that is inclined upward from the rear to the front, and the front end portion is located above the portion covering the upper surface of the box 1 , and the front end portion is arranged higher than the upper surface of the box 1 . The first claw portion 3c is further upward. Furthermore, the front end portion of the hinge 30 may also be disposed between the top plate 3 and the first claw portion 3c. With such a structure, since the front end of the hinge 30 is hidden in the first claw portion 3c, the user can be prevented from touching the front end of the hinge 30.

As described above, the refrigerator 100 of Embodiment 1 is provided with: the box 1 having a front opening; the door 2 being installed on the box 1 and opening and closing the front opening; and the top plate 3 being installed to cover the box 1 At least part of the upper surface of the door 2 and at least part of the upper surface of the door 2, and has a first claw portion 3c extending from the lower side of the front end toward the rear; and a single reinforcing sheet metal piece 6, which is installed to cover the box body 1 At least part of the upper surface of the front side of the door 2 and at least part of the upper surface of the door 2. Furthermore, the reinforcing sheet metal 6 is attached to the top plate 3 in a state where the front end portion is fitted with the first claw portion 3 c of the top plate 3 .

According to the refrigerator 100 of Embodiment 1, since the top plate 3 is installed on the upper surface of the box 1 and covers at least a part of the upper surface of the box 1 and at least a part of the upper surface of the door 2 , a relatively high temperature can be ensured on the top plate 3 . Wide space. Furthermore, since the refrigerator 100 according to Embodiment 1 is configured to reinforce the top panel 3 with a single reinforcing sheet metal member 6, the number of parts can be reduced. In addition, the reinforcing sheet metal 6 is installed to cover at least part of the upper surface of the front side of the box 1 and the upper surface of the door 2 At least a part of the surface can not only increase the strength of the side portions of the top plate 3 but also increase the strength of the central portion, thereby suppressing the deformation of the top plate 3 .

Furthermore, the refrigerator 100 of Embodiment 1 is provided with: a hinge 30 installed from the outside so as to span from the upper surface of the cabinet 1 to the upper surface of the door 2; and an assembly 5 made of sheet metal and installed from the inside. to the top of box 1. In addition, the top plate 3 has a second claw portion 3a in front of the lower surface; the hinge 30 and the assembly part 5 are fixed with screws across the upper surface of the box 1; the assembly part 5 has a fixture 4, and the fixture 4 is It is L-shaped and when the assembly 5 and the hinge 30 are fixed with screws, the fixture 4 protrudes upward and forward from the upper surface opening 1c formed on the upper surface of the box 1 . In this way, the top plate 3 is fixed to the rear surface of the box 1 with screws in a state where the second claw portion 3a is fitted with the fixture 4 protruding from the upper surface opening 1c.

According to the refrigerator 100 of Embodiment 1, since the assembly member 5 becomes a common fixing plate metal member for the hinge 30 and the top panel 3 , there is no need to prepare a separate assembly member for the top panel 3 . Furthermore, the top plate 3 is fixed to the rear surface of the box 1 with screws in a state where the second claw portion 3a is fitted with the fixture 4 protruding from the upper surface opening 1c. That is, since the top plate 3 can be fixed to the box 1 only by screws on the rear surface of the box 1, the work steps can be simplified.

Furthermore, in the refrigerator 100 of Embodiment 1, the box 1 has an outer box 1b forming an outer shell and an inner box 1a forming an internal space, and the heat insulating material 8 is filled between the outer box 1b and the inner box 1a. In this way, the assembly 5 is pushed toward the outer box 1b side by the pressure of the heat insulating material 8, and is fixed to the box 1.

According to the refrigerator 100 of Embodiment 1, the assembly 5 is pushed toward the outer box 1 b side by the pressure of the heat insulating material 8 and fixed to the box 1 . That is, even if the assembly 5 is not fixed near the upper surface opening 1c with screws, it can be stably fixed to the outer box 1b. Therefore, there is no need to screw the The work of fixing the assembly part 5 near the opening 1c on the upper surface can simplify the work steps.

Furthermore, in the refrigerator 100 according to Embodiment 1, the surface of the reinforcing sheet metal 6 is formed with an uneven undulating shape 6a.

According to the refrigerator 100 of Embodiment 1, the surface of the reinforcing sheet metal 6 is formed with an uneven undulating shape 6 a. Therefore, the strength of the reinforcing sheet metal 6 is increased, and even when heavy household appliances such as microwave ovens or electric cookers are placed on the top plate 3, the top plate 3 can be prevented from bending, and the door 2 and the box 1 can also be prevented from bending. The parts are damaged and the design quality is reduced.

Reinforcement sheet metal parts 6. Furthermore, since the lower surface of the reinforcing sheet metal piece 6 is covered by the top mounting member 7, even if the reinforcing sheet metal piece 6 falls off, it can be prevented from falling near the feet because it cannot be seen from the outside. The sheet metal parts 6 are reinforced, so the design can be improved.

Since the material of the roof mounting member 7 is synthetic resin, the shape can be determined relatively freely. By arranging the top plate mounting member 7 under the reinforcing sheet metal 6, the gap generated between the top plate 3 and the refrigerating compartment door 21 and between the reinforcing sheet metal 6 and the refrigerating compartment door 21 can be adjusted. In addition, when a gap is formed between the top plate 3 and the reinforcing sheet metal 6, when an object is placed on the top plate 3, a part of the top plate 3 may sink due to the load, and the top plate 3 may come into contact with the reinforcing sheet metal 6. Roof plate 3 may be damaged. In order to solve this problem, as shown in Figure 17, a plurality of upwardly protruding columnar structures, that is, protrusions 7b, can be provided on the upper surface of the top plate mounting member 7 along the width direction to fill the gap between the top plate 3 and the top plate 3. gap.

Thus, in this state, the top plate 3 is fixed to the rear surface of the box 1 with screws.

Here, the planar size of the roof mounting member 7 is set to be several millimeters larger than the reinforcing sheet metal member 6 so that the plane size of the reinforcing sheet metal member 6 converges within the plane of the roof mounting member 7 . Thereby, even when a large load is applied to the protruding portion 3 d of the top plate 3 , the reinforcing sheet metal 6 can be prevented from bending using the top plate mounting member 7 as a fulcrum. Furthermore, among the first claw portions 3 c of the protruding portion 3 d of the top plate 3 , the front end portion of the top plate mounting member 7 is closer to the shape of the top plate 3 than the front end portion of the reinforcing sheet metal member 6 . The top plate 3 is also a decorative member. Since it is a resin product, care must be taken to avoid damage due to friction with other parts. In this regard, if the roof mounting member 7 is preset to be larger than the reinforcing sheet metal 6, the reinforcing sheet metal 6 will not be arranged on the outside, and the friction with the reinforcing sheet metal 6 and the damage to the roof 3 caused by the friction with the reinforcing sheet metal 6 when the roof 3 is installed can be reduced. Risk of injury.

As shown in FIGS. 19 and 20 , the rib 7 c is disposed so that when the roof mounting member 7 is installed on the box 1 , it is located between the box 1 and the refrigerator compartment door 21 , and the rear side of the rib 7 c is located between the box 1 and the box 1 . 1 contact position. With this structure, when the force received by the top plate 3 and the reinforcing sheet metal 6 is transmitted to the top mounting part 7, the force can be dispersed toward the box 1 side, so the deformation of the top mounting part 7 can be prevented.

As described above, the refrigerator 100 according to Embodiment 2 is provided with the ceiling mounting member 7 provided between the box 1 and the reinforcing sheet metal 6 . In addition, the top plate mounting member 7 has a third claw portion on the upper surface for pseudo-fixing the reinforcing sheet metal 6.

In the covered state, the roof mounting piece 7 and the reinforcing sheet metal piece 6 are jointly installed on the upper surface of the box 1 .

According to the refrigerator 100 of Embodiment 2, in a state where the lower surface of the reinforcing sheet metal 6 is covered by the roof mounting member 7 , the roof mounting member 7 and the reinforcing sheet metal 6 are jointly installed on the box. The upper surface of body 1. Therefore, when the user opens the refrigerator compartment door 21, since the lower surface of the reinforcing plate metal part 6 is covered by the roof mounting part 7, the user will not see the reinforcing plate metal part 6 and cannot directly touch the reinforcing plate metal part 6. . Furthermore, since the lower surface of the reinforcing sheet metal piece 6 is covered by the top mounting member 7, even if the reinforcing sheet metal piece 6 falls off, it can be prevented from falling near the feet because it cannot be seen from the outside. The sheet metal parts 6 are reinforced, so the design can be improved.

Furthermore, in the refrigerator 100 according to Embodiment 2, a columnar structure protruding upward is provided on the upper surface of the ceiling mounting member 7 .

According to the refrigerator 100 of Embodiment 2, since the upper surface of the top plate mounting member 7 is provided with a columnar structure protruding upward, when items are placed on the top plate 3, the deformed top plate 3 can be supported by the structure, so that the deformation of the top plate 3 can be suppressed. Deformation of top plate 3.

Furthermore, in the refrigerator 100 of Embodiment 2, the rib 7c protruding downward is provided on the lower surface of the top plate mounting member 7 along the width direction. In this way, when the roof mounting bracket 7 is installed on the box 1, the rib 7c is located between the box 1 and the door 2, and the rear side surface of the rib 7c is in contact with the box 1.
