[First embodiment]
<Overall configuration of refrigerator>

First, the overall configuration of the refrigerator 1 according to the first embodiment will be described. Figure 1 shows the external appearance of the refrigerator 1 as seen from the front.

The exterior of the refrigerator 1 is mainly composed of an insulated box 90. This insulated box 90 forms the storage space of the refrigerator 1. The storage space formed by the insulated box 90 is divided by multiple partitions extending horizontally into, for example, from the top, a refrigerator compartment 11, a vegetable compartment 12, a first freezer area 13, an ice making/storage area 14, and a second freezer area 15. In the following, the first freezer area 13, the ice making/storage area 14, and the second freezer area 15 are collectively referred to as the freezer compartment 20.

The refrigerator compartment 11 is provided with refrigerator compartment doors 11a and 11b that open like a double door and are divided into left and right halves. The vegetable compartment 12 is provided with a pull-out vegetable compartment door 12a. The first freezer area 13 is provided with a pull-out freezer compartment door 13a. The ice making and storage area 14 is provided with a pull-out ice making compartment door 14a. The second freezer area 15 is provided with a pull-out freezer compartment door 15a.

In this embodiment, each of the pull-out doors (i.e., vegetable compartment door 12a, freezer compartment door 13a, ice compartment door 14a, freezer compartment door 15a, etc.) has a handle 31 at its upper end.

In the following description, the surface on which the door is provided is referred to as the front or front surface of the refrigerator. Based on the front surface, the surfaces of the refrigerator 1 are referred to as the top, side, back, and bottom surfaces based on the positions of the refrigerator 1 when it is installed in a normal state. In addition, the left-right direction (horizontal direction perpendicular to the up-down direction) when the refrigerator 1 is placed on the installation surface is referred to as the left-right direction of the refrigerator 1 (or the vegetable compartment door 12a, etc.). In addition, the up-down direction (vertical direction perpendicular to the left-right direction) when the refrigerator 1 is placed on the installation surface is referred to as the up-down direction of the refrigerator 1 (or the vegetable compartment door 12a, etc.). In addition, the side located on the left side when viewed from the front side of the refrigerator 1 is referred to as the left side of the refrigerator 1, and the side located on the right side when viewed from the front side of the refrigerator 1 is referred to as the right side of the refrigerator 1.
<Internal structure of the refrigerator>

Next, the internal structure of the refrigerator 1 according to this embodiment will be described with reference to Figs. 2 to 7. The refrigerator 1 is provided with an RV shelf 21 for separating the refrigeration compartment 11 and the vegetable compartment 12 at approximately the center of the top and bottom of the insulated box 90. In addition, a VF shelf 22 for separating the vegetable compartment 12 and the freezer compartment 20 is provided.

A partition frame 23 is attached below the front end of the VF shelf 22 to separate the open area of the freezer compartment 20. The partition frame 23 is a long, narrow frame that is installed horizontally on the front part of the refrigerator 1 where the doors 13a, 14a, and 15a are located. The partition frame 23 separates the first freezer area 13 below from the ice making and storage area 14 and second freezer area 15 above.

In particular, in this embodiment, the partition frame 23 is fixed to the insulating box 90 and the liner 94 after the urethane injected into the inside of the insulating box 90 and the VF shelf 22 is foamed.

In this embodiment, rails 96 for sliding cases placed in the first freezing area 13 in the front-rear direction and rails for sliding cases placed in the ice making and storage area 14 in the front-rear direction are formed directly on the liner 94 of the insulated box 90, and rails 97 for sliding cases placed in the second freezing area 15 in the front-rear direction are made of a separate member that is attached to the liner 94 before urethane foaming. The rails 97 are preferably made thicker than the liner 94 of the insulated box 90 or made of a harder material so that they have greater strength than the liner 94.

In addition, in this embodiment, a door opening/closing sensor 27 for detecting the opening/closing of the door 13a of the first freezing area 13 is attached to the lower part of the partition frame 23. The power lines and signal lines (see FIG. 10) to the door opening/closing sensor 27 run from a control board (not shown) outside the insulating box 90 through the urethane of the insulating box 90 and are connected to the door opening/closing sensor 27. In particular, in this embodiment, the power lines and signal lines are configured to be connected to the door opening/closing sensor 27 after the urethane foaming.

In the refrigerator 1 according to this embodiment, a cooling mechanism 40 including a compressor 41, an evaporator 42, and a fan 43 is disposed behind the freezer compartment 20 provided on the lower level. The compressor 41 is disposed outside the insulated box 90, while the evaporator 42 and the fan 43 are disposed inside the insulated box 90 and behind the evaporator cover 45. The evaporator cover 45 is provided with a lower evaporator cover 45A that covers the lower part of the back surface of the freezer compartment 20, and an upper evaporator cover 45B that covers the upper part of the back surface of the freezer compartment 20.

In particular, the refrigerator 1 of this embodiment is equipped with a cooling mechanism 40 that is large enough to reach a position higher than the height of the freezer compartment 20, as shown in Figs. 6 and 7. More specifically, the upper eva cover 45B, the cold air outlet, and the fan 43 are arranged up to a position higher than the upper end of the front of the freezer compartment 20, i.e., the front half of the underside of the VF shelf 22. In other words, the refrigerator 1 is equipped with a relatively large cooling mechanism 40 that reaches a position higher than the ceiling on the front side of the freezer compartment 20.

In this embodiment, as shown in Figs. 7 to 9, the ceiling of the freezer compartment 20, i.e., the rear part of the underside 22B of the VF shelf 22, is configured to be concave upward so that the cold air cooled by the evaporator 42 can flow smoothly into the freezer compartment 20. More specifically, the underside 22B of the VF shelf 22 has an inclined surface 22C formed in the center of the rear part, which rises upward toward the rear. In other words, the duct, fan, and their vicinity that send the cold air from the fan 43 to the refrigerator compartment 11 on the underside 22B of the VF shelf 22 are concave upward.

In this way, in this embodiment, even though a relatively large cooling mechanism 40 is provided and the size of the vegetable compartment is ensured, the cold air cooled by the evaporator 42 can flow smoothly into the freezer compartment 20.

Furthermore, in this embodiment, the front of the lower part of the V-duct 51, which is attached to the rear of the vegetable compartment 12 and sends the cold air cooled by the evaporator 42 to the upper part of the refrigerator compartment 11, is covered with a urethane filling member, thereby improving the insulation performance between the internal space of the V-duct 51 and the vegetable compartment 12. More specifically, in this embodiment, a protrusion 22X is formed at the rear of the VF shelf 22, and urethane 25 is filled up to the protrusion 22X.

In other words, the VF shelf 22 in this embodiment is formed so as to bend upward just before the V duct 51 in the left-right center. That is, just before the V duct 51 in the left-right center of the VF shelf 22, the upper surface of the VF shelf 22 is bent upward to form a convex portion 22X, and the lower surface of the VF shelf 22 is bent upward to form an inclined surface 22C. The inclined surface 22C ensures an area for arranging the fan 43, the air outlet, and the upper eva cover 45B, while the urethane 25 filled in the convex portion 22X provides insulation between the inside of the V duct 51 and the vegetable compartment 12.

More specifically, when the flap 53 of the R damper 52 in the V duct 51 is closed, it is preferable that the upper end of the flap 53 and the upper end of the protrusion 22X are at the same height, the upper end of the protrusion 22X is at a higher position, or even if the upper end of the flap 53 is higher, it is configured so that it is only a few millimeters higher. In other words, when the flap 53 is closed, it is preferable that the upper end of the protrusion 22X reaches near the upper end of the area where the cold air from the fan 43 reaches. In further other words, when viewed from the front of the refrigerator 1, it is preferable that the protrusion 22X that rises upward from the VF shelf 22 covers a part of the area where the cold air from the fan 43 directly reaches when the flap 53 is closed that is higher than the VF shelf 22.

In a normal refrigerator, even if the R damper 52 is closed, the cold air cooled by the evaporator 42 flows up to the underside of the R damper 52 or the flap 53, so the lower part of the V duct 51 becomes too cold, making it easy for condensation to form on the front of the V duct 51. However, with the refrigerator 1 according to the present embodiment, the above configuration can reduce the possibility of condensation in the vegetable compartment 12 occurring due to the lower part of the V duct 51 becoming too cold.

The refrigerator 1 according to this embodiment is configured as follows to secure the partition frame 23 to the freezer compartment 20 after the urethane foaming.

Referring to FIG. 10, in this embodiment, a door opening/closing sensor 27 for detecting the opening/closing of the door 13a of the first freezing area 13 is attached to the partition frame 23. Then, electric wires 28 and connectors 29 for connection to the door opening/closing sensor 27 are drawn out from the liner 94 of the freezing chamber 20. More specifically, the electric wires 28 and connectors 29 are drawn out from the rear of the portion of the liner 94 of the freezing chamber 20 of the insulated box 90 where the partition frame 23 is attached. In this embodiment, the electric wires 28 and connectors 29 exit from a hole opened in the liner 94, and are then drawn out from a drawing opening 97B formed in the front part of the rail 97.

Behind the outlet 97B formed in the liner 94 or rail 97, a storage section 95X is formed for storing the electric wires 28 and connectors 29 during urethane foaming. In this embodiment, the lower surface and back surface of the storage section 95X are formed by the rib 95 formed in the liner 94 of the second freezer area 15, the upper surface of the storage section 95X is formed by the lower surface of the rail 97, and the front surface of the storage section 95X is formed by the back surface of the extension section 97A which is formed by extending the front part of the rail 97 downward. In this way, a recess is formed in the side surface of the freezer compartment 20, and the electric wires 28 and connectors 29 are stored in the recess during urethane foaming.

As described above, the rail 97 is formed to be thicker than the liner 94 or is made of a harder material than the liner 94, and the front surface of the liner 94 is formed with screw holes 97C for fixing the partition frame 23.

In particular, in this embodiment, the outlet 97B for the electric wires 28 and the connector 29 is formed at a position that overlaps with the right end of the partition frame 23 when viewed from the front. In other words, when the partition frame 23 is attached to the insulating box body 90, the outlet 91 is configured not to be visible from the front of the refrigerator 1.

The storage section 95X for the electric wires 28 and the connectors 29 is formed at a position that overlaps with the end of the partition frame 23 when viewed from the front. In other words, when the partition frame 23 is attached to the insulating box body 90, the storage section 95X is configured to be difficult to see from the front of the refrigerator 1.

The liner 94 that constitutes the freezer compartment 20 has a front end portion, to which the left and right ends of the partition frame 23 are fitted and fixed, and recesses 91R and 91L are formed.
<Refrigerator manufacturing method>

In this configuration, the refrigerator 1 according to this embodiment is assembled and manufactured as follows.

Referring to FIG. 11, first, the electric wire 28 and the connector 29 are pulled out from the pull-out opening 97B, and then the electric wire 28 and the connector 29 are stored in the storage section 95X (step S102). In this embodiment, the worker covers the electric wire 28 and the connector 29 with tape so that they do not protrude from the storage section 95X.

Next, as shown in FIG. 12, reinforcing members 24L, 24R are attached to the recesses 91L, 91R for fixing the partition frame 23 (step S104). Attaching the reinforcing members 24L, 24R prevents the shape of the recesses 23L, 23R from collapsing when the urethane is foamed.

A jig 200 as shown in FIG. 13 is prepared (step S106). The upper part 202 of the jig 200 slides vertically relative to the lower part 201. A convex shape 202B is formed at the rear of the upper part 202. The convex shape 202B has the same shape as the concave shape at the rear of the lower surface 22B of the VF shelf 22.

As shown in Figures 14 and 15, the jig 200 is inserted from the front of the refrigerator 1 into the freezer compartment 20, i.e., the area below the VF shelf 22 (step S108).

When the jig 200 is inserted all the way, the upper part 202 of the jig 200 is lifted as shown in FIG. 16. This causes the rear convex shape 202B of the jig 200 to come into contact with the ceiling at the rear of the freezer compartment 20, i.e., the rear inclined surface 22C and the recessed portion of the lower surface 22B of the VF shelf 22, as shown in FIG. 7 and FIG. 9 (step S110).

In this state, urethane is injected into the insulating box 90 and foamed (step S112).

After the urethane foaming, the jig 200 is removed from the insulating box (step S114).

As shown in FIG. 17, the evaporator 42 is attached to the rear end of the freezer compartment 20 (step S116).

As shown in FIG. 17, attach the fan 43 to the rear of the upper part of the lower eva cover 45A (step S118).

As shown in FIG. 17, the lower eva cover 45A is attached to the rear end of the freezer compartment 20 (step S120).

As shown in Figures 17 to 21, the upper eva cover 45B is attached to the front of the upper part of the lower eva cover 45A (step S122). With reference to Figures 20 and 21, the lower eva cover 45A and the upper eva cover 45B are collectively referred to as the eva cover 45.

More specifically, in this embodiment, the lower eva cover 45A is attached to the rear of the freezer compartment 20, and then the upper eva cover 45B is attached. In this embodiment, the upper eva cover 45B is attached behind the rear inclined surface 22C of the VF shelf 22, and the upper end of the upper eva cover 45B reaches a position higher than the ceiling of the freezer compartment 20, i.e., a position higher than the front of the lower surface 22B of the VF shelf 22. Therefore, the lower eva cover 45A is attached, and then the upper eva cover 45B is attached to the recessed portion at the rear of the lower surface 22B of the VF shelf 22.

Then, the V duct 51 shown in Figures 22 and 23 is attached to the rear end of the upper surface of the VF shelf 22 (step S124). When attached to the back of the vegetable compartment 12, the V duct 51 has a shape in which the lower half protrudes further forward than the upper half. In other words, the V duct 51 is configured so that it bulges forward as it approaches the lower part, that is, it is configured so that it is recessed backward as it approaches the upper part. This allows the cold air from the fan 43 to flow smoothly into the duct passage 51Y toward the refrigerator compartment 11.

In particular, in this embodiment, protrusions 51L and 51R are formed on the lower part of the back surface of the V duct 51. As shown in FIG. 24, the worker hooks the lower end 51X of the front surface of the V duct 51 onto the back surface of the convex portion 22X of the VF shelf 22, and while the protrusions 51L and 51R are in contact with the back surface of the vegetable compartment 12, i.e., the liner 94 of the heat-insulating box 90, pushes the upper part of the V duct 51 backward, thereby sliding the protrusions 51L and 51R downward. At this time, the protrusions 51L and 51R serve as fulcrums, and a force (forward) opposite to the force direction (rearward) applied to the upper part of the V duct 51 is generated at the lower end 51X. Therefore, the lower end 51X is reliably pushed into the back surface of the convex portion 22X of the VF shelf 22. In this way, when the V duct 51 is fixed to the back of the vegetable compartment 12, the V duct 51 is pressed into the back of the protruding portion 22X of the VF shelf 22, preventing cold air leakage and a decrease in insulation.

Remove the tape from the storage section 95X and take out the electric wires 28 and connectors 29 from the storage section 95X (step S126).

The connector 29 is connected to the door opening/closing sensor 27 of the partition frame 23 (step S128). More specifically, in this embodiment, referring to FIG. 25, a hole 23X for passing the connector is formed at the end of the partition frame 23. The worker passes the connector 29 through the hole 23X and then connects it to the door opening/closing sensor 27. Thus, the excess electric wires 28 and connectors 29 can be stored inside the partition frame 23, and the electric wires 28 and connectors 29 can be prevented from being seen or touched by the user.

The door opening/closing sensor 27 is fixed to the bottom of the partition frame 23 (step S130).

As shown in Figures 25 and 26, both ends of the partition frame 23 are fitted into the reinforcing members 24L, 24R of the recesses 91L, 91R (step S132).

Both ends of the partition frame 23 are screwed into the screw holes 97C on the front surface of the rail 97 (step S134).

In this way, with regard to the refrigerator 1 in this embodiment, while being equipped with a relatively large cooling mechanism 40 and while ensuring the size of the vegetable compartment, it is possible to allow the cold air cooled by the evaporator 42 to flow smoothly into the freezer compartment 20, prevent the front of the V-duct 51 from becoming too cold, make it easy to install the V-duct 51, and install a door opening/closing sensor 27 on the partition frame 23.
[Second embodiment]

In the above embodiment, the recesses 91L, 91R for fixing the partition frame 23 are attached closer to the inside of the freezer compartment 20 than the liner 94, but the recesses 91L, 91R for fixing the partition frame 23 may also be attached closer to the urethane side than the liner 94.
[Third embodiment]

Alternatively, the rails 97 may be extended further forward and integrated with the reinforcing members 24L, 24R.
[Fourth embodiment]

In the above embodiment, the vegetable compartment 12 is provided above the freezer compartment 20. However, the above-mentioned various techniques can also be applied to a refrigerator 1 in which the refrigerator compartment 11 is provided above the freezer compartment 20. The RF shelf separating the refrigerator compartment 11 and the freezer compartment 20 may have a convex shape at the rear of the upper surface and be filled with urethane, or may have an incline or a recess at the rear of the lower surface to accommodate a fan, an upper evaporative cover, an air outlet, etc.
