DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0008] Hereinafter, each embodiment of the present invention will be described with reference to the drawings. In the following description, the same components are denoted by the same reference numerals. Their names and functions are also the same. Therefore, detailed description thereof will not be repeated. [First embodiment] <Overall configuration of refrigerator>

[0009] First, the overall configuration of a refrigerator 1 according to the first embodiment will be described. Fig. 1 shows the external appearance of the refrigerator 1 as seen from the front.

[0010] 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 a plurality of horizontally extending partitions into, for example, 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 that order from the top. In the following description, 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.

[0011] 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.

[0012] In this embodiment, each of the drawer-type doors (that is, vegetable compartment door 12a, freezer compartment door 13a, ice-making compartment door 14a, freezer compartment door 15a, etc.) is provided with a handle portion 31 at its upper end portion.

[0013] 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 and viewed from the front 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 and viewed from the front 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>

[0014] Next, the internal structure of the refrigerator 1 according to this embodiment will be described with reference to Fig. 2 to Fig. 7. The refrigerator 1 is provided with an RV shelf 21 for separating the refrigerator compartment 11 and the vegetable compartment 12 at approximately the center in the vertical direction of the insulated box body 90. In addition, a VF shelf 22 for separating the vegetable compartment 12 and the freezer compartment 20 is provided.

[0015] A partition frame 23 for dividing the open part of freezer compartment 20 is attached below the front end of VF shelf 22. Partition frame 23 is a long and narrow frame installed horizontally on the front part of refrigerator 1 where doors 13a, 14a, 15a are located. Partition frame 23 divides the first freezer area 13 at the bottom from the ice making and storage area 14 and second freezer area 15 at the top.

[0016] 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 has been foamed.

[0017] In this embodiment, rails 96 for sliding a case placed in first freezing area 13 in the front-rear direction and rails for sliding a case placed in ice making and storage area 14 in the front-rear direction are formed directly on liner 94 of insulated box 90, while rails 97 for sliding a case placed in second freezing area 15 in the front-rear direction are made of a separate member that is attached to liner 94 before urethane foaming. Rails 97 are preferably made thicker than liner 94 of insulated box 90 or made of a harder material so that they have greater strength than liner 94.

[0018] 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 heat-insulating box 90 through the urethane of the heat-insulating box 90 and are connected to the door opening / closing sensor 27. Particularly in this embodiment, the power lines and signal lines are configured to be connected to the door opening / closing sensor 27 after the urethane is foamed.

[0019] 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 in the lower stage. The compressor 41 is disposed outside the heat-insulating box 90, while the evaporator 42 and the fan 43 are disposed inside the heat-insulating box 90 and behind the evaporator cover 45. As for the evaporator cover 45, 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 are attached.

[0020] 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 Fig. 6 and Fig. 7. More specifically, the upper evaporative cover 45B, the cold air outlet, and the fan 43 are arranged up to a position higher than the upper end of the front part of the freezer compartment 20, i.e., the front half of the lower surface 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.

[0021] In this embodiment, as shown in Fig. 7 to Fig. 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 have a shape that is concave toward the top so that the cold air cooled by the evaporator 42 can smoothly flow 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 and fan that send the cold air from the fan 43 to the refrigerator compartment 11 and the vicinity thereof on the underside 22B of the VF shelf 22 are concave toward the top.

[0022] In this manner, in the present 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 be allowed to flow smoothly into the freezer compartment 20.

[0023] Furthermore, in this embodiment, the front surface of the lower portion of V duct 51, which is attached to the rear of vegetable compartment 12 and sends the cold air cooled by evaporator 42 to the upper portion of refrigerator compartment 11, is covered with a urethane filling member, thereby improving the insulation performance between the internal space of V duct 51 and vegetable compartment 12. More specifically, in this embodiment, protrusion 22X is formed at the rear of VF shelf 22, and urethane 25 is filled even into protrusion 22X.

[0024] In other words, the VF shelf 22 according to this embodiment is formed so as to bend upward just before the V duct 51 in the left-right center portion. That is, just before the V duct 51 in the left-right center portion 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 evaporative cover 45B, while the urethane 25 filled in the convex portion 22X provides thermal insulation between the inside of the V duct 51 and the vegetable compartment 12.

[0025] 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, or 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 several mm 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 to which 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 rising upward from the VF shelf 22 covers a part higher than the VF shelf 22 within the area to which the cold air from the fan 43 directly reaches when the flap 53 is closed.

[0026] In a normal refrigerator, even if R damper 52 is closed, the cold air cooled by evaporator 42 flows up to the underside of R damper 52 or flap 53, so the lower part of V duct 51 becomes too cold, and condensation is likely to occur on the front surface of V duct 51. However, in the refrigerator 1 according to the present embodiment, the above-mentioned configuration makes it possible to reduce the possibility of condensation occurring in vegetable compartment 12 due to the lower part of V duct 51 becoming cold.

[0027] The refrigerator 1 according to the present embodiment is configured as follows in order to fix the partition frame 23 to the freezer compartment 20 after the urethane foaming.

[0028] 10, in this embodiment, a door opening / closing sensor 27 for detecting opening / closing of the door 13a of the first freezing area 13 is attached to the partition frame 23. Then, an electric wire 28 and a connector 29 for connection to the door opening / closing sensor 27 are drawn out from a liner 94 of the freezing chamber 20. More specifically, the electric wire 28 and the connector 29 are drawn out from the rear of the portion of the liner 94 of the freezing chamber 20 of the thermally insulated box 90 where the partition frame 23 is attached. In this embodiment, the electric wire 28 and the connector 29 exit from a hole opened in the liner 94, and then are drawn out from a drawing opening 97B formed in the front part of the rail 97.

[0029] Behind the outlet 97B formed in the liner 94 or the rail 97, a storage section 95X for storing the electric wires 28 and the connector 29 during urethane foaming is formed. In this embodiment, the lower surface and rear surface of the storage section 95X are formed by the rib 95 formed in the liner 94 in the second freezing 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 rear surface of the extension section 97A formed by extending the front portion of the rail 97 downward. In this way, a recess is formed in the side surface of the freezing chamber 20, and the electric wires 28 and the connector 29 are stored in the recess during urethane foaming.

[0030] As described above, the rail 97 is molded to be thicker than the liner 94 or is made of a harder material than the liner 94, and a screw hole 97C for fixing the partition frame 23 is formed on the front surface of the liner 94.

[0031] Particularly in this embodiment, the outlet 97B for the electric wires 28 and the connector 29 is formed at a position overlapping the right end of the partition frame 23 in a front view. 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.

[0032] Further, the storage section 95X for the electric wires 28 and the connectors 29 is formed at a position overlapping an end of the partition frame 23 in a front view. 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.

[0033] In the front end portion of the liner 94 constituting the freezing compartment 20, recesses 91R and 91L are formed in portions into which the left and right ends of the partition frame 23 are fitted and fixed. <Refrigerator manufacturing method>

[0034] In this configuration, the refrigerator 1 according to the present embodiment is assembled and manufactured as follows.

[0035] 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.

[0036] 12, the reinforcing members 24L, 24R are attached to the recesses 91L, 91R for fixing the partition frame 23 (step S104). By attaching the reinforcing members 24L, 24R, the shape of the recesses 23L, 23R is prevented from collapsing when the urethane is foamed.

[0037] A jig 200 as shown in Fig. 13 is prepared (step S106). The jig 200 has an upper part 202 that slides vertically relative to a lower part 201. A convex shape 202B is formed in the rear part of the upper part 202. The convex shape 202B has the same shape as the concave part in the rear part of the lower surface 22B of the VF shelf 22.

[0038] As shown in Figs. 14 and 15, the jig 200 is placed into the freezer compartment 20, that is, the area below the VF shelf 22, from the front of the refrigerator 1 (step S108).

[0039] When the jig 200 is inserted all the way, the upper portion 202 of the jig 200 is lifted as shown in Fig. 16. This causes the rear convex shape 202B of the jig 200 to abut against 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 Figs. 7 and 9 (step S110).

[0040] In this state, urethane is injected into the heat-insulating box 90 and foamed (step S112).

[0041] After the urethane foaming, the jig 200 is removed from the heat-insulating box (step S114).

[0042] As shown in FIG. 17, the evaporator 42 is attached to the rear end of the freezing compartment 20 (step S116).

[0043] As shown in FIG. 17, the fan 43 is attached to the rear surface of the upper part of the lower evaporative cover 45A (step S118).

[0044] As shown in FIG. 17, the lower evaporative cover 45A is attached to the rear end of the freezing compartment 20 (step S120).

[0045] 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 FIGS. 20 and 21, the lower eva cover 45A and the upper eva cover 45B are collectively referred to as the eva cover 45.

[0046] More specifically, in this embodiment, the upper eva cover 45B is attached after the lower eva cover 45A is attached to the back surface of the freezer compartment 20. The upper eva cover 45B in this embodiment is attached rearward of 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 part of the lower surface 22B of the VF shelf 22. Therefore, the upper eva cover 45B is attached to the recessed part at the rear of the lower surface 22B of the VF shelf 22 after the lower eva cover 45A is attached.

[0047] Then, the V duct 51 shown in Fig. 22 and Fig. 23 is attached to the rear end of the upper surface of the VF shelf 22 (step S124). When attached to the rear 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 in a shape that bulges forward as it approaches the lower part, that is, a shape that is recessed backward as it approaches the upper part. This allows the cool air from the fan 43 to flow smoothly into the duct passage 51Y toward the refrigerator compartment 11.

[0048] Particularly, 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 on the back surface of the convex portion 22X of the VF shelf 22, and in a state in which the protrusions 51L and 51R are in contact with the back surface of the crisper 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 in 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. When the V duct 51 is fixed to the rear surface of the vegetable compartment 12 in this manner, the V duct 51 is press-fitted into the rear surface of the protruding portion 22X of the VF shelf 22, preventing cold air leakage and a decrease in thermal insulation.

[0049] The tape is removed from the storage section 95X, and the electric wires 28 and the connector 29 are taken out from the storage section 95X (step S126).

[0050] 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 through 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. Therefore, 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.

[0051] The door opening / closing sensor 27 is fixed to the lower part of the partition frame 23 (step S130).

[0052] As shown in FIGS. 25 and 26, both end portions of the partition frame 23 are fitted into the reinforcing members 24L, 24R of the recesses 91L, 91R (step S132).

[0053] Both ends of the partition frame 23 are fastened with screws into the screw holes 97C in the front surface of the rail 97 (step S134).

[0054] In this way, the refrigerator 1 according to this embodiment is 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 the door opening / closing sensor 27 on the partition frame 23. [Second embodiment]

[0055] 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]

[0056] Alternatively, the rails 97 may be extended further forward and integrated with the reinforcing members 24L, 24R. [Fourth embodiment]

[0057] In the above embodiment, the vegetable compartment 12 is provided above the freezer compartment 20. However, the above-mentioned various technologies 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 a slope or a concave portion at the rear of the lower surface to accommodate a fan, an upper evaporative cover, an air outlet, etc. [summary]

[0058] In the above embodiment, a refrigerator is provided which comprises a freezer compartment, a vegetable compartment or refrigerator compartment above the freezer compartment, and a duct arranged at the rear of the vegetable compartment or refrigerator compartment, in which a convex portion is formed from the bottom surface of the vegetable compartment or refrigerator compartment to cover the lower part of the front surface of the duct, and urethane is filled into the convex portion.

[0059] Preferably, the convex portion is configured to cover a portion below the flap of the damper when the damper is closed inside the duct in a front view.

[0060] Preferably, a rearwardly raised portion is formed at the lower portion of the rear surface of the duct, and the duct is attached to the rear surface of the vegetable compartment or the refrigerator compartment by hooking the lower end portion of the front surface of the duct onto the rear surface of the protrusion, and then, with the raised portion in contact with the rear surface of the vegetable compartment or the refrigerator compartment, pushing the upper portion of the duct rearward and sliding the raised portion downward.
