[0023] Hereinafter, a refrigerator 1 according to one embodiment of the present invention will be described based on the accompanying drawings. Furthermore, the following embodiments are illustrative and the scope of the invention is not limited thereto. Various omissions, substitutions, and modifications can be made to the following embodiments without departing from the spirit of the invention. The following embodiments and their variations are included within the scope of the invention described in the patent claims and their equivalents.

[0024] Furthermore, in the following description, left and right, front and back, and up and down refer to the directions when viewing the refrigerator from the front, with left and right corresponding to the width of the refrigerator. Additionally, right, left, up, down, inside, back, and near front refer to the position, side, etc., when viewing the refrigerator from the front unless otherwise specified. Furthermore, the side of the inner box 4 of the refrigerator 1 facing the storage compartment is designated as the inner side, and the side facing the outer box 3 through the insulation material is designated as the insulation area side.

[0025] (1) Structure of refrigerator 1

[0026] The structure of refrigerator 1 is described with reference to the attached diagram.

[0027] like Figure 1 as well as Figure 2 As shown, the refrigerator 1 has a refrigerator body 2 with an opening at the front. The refrigerator body 2 has an outer box 3 made of steel plate and an inner box 4 made of synthetic resin. An insulation area 5 is formed between the outer box 3 and the inner box 4 to store insulation materials such as plate-shaped insulation material 5a and foamed insulation material 5b.

[0028] The interior space of the refrigerator body 2 is divided vertically by an insulated partition wall 6. Above the insulated partition wall 6, there is a space for a refrigerator compartment 20 and a vegetable compartment 22 (hereinafter sometimes referred to as a refrigerator storage space), and below the insulated partition wall 6, there is a space for an ice-making compartment 24, a first freezer compartment 26, and a second freezer compartment 28 (hereinafter sometimes referred to as a freezer storage space).

[0029] The cold storage compartment 20 is an upper storage compartment formed by dividing the cold storage space inside a single inner box 4 vertically using a partition 50. The vegetable compartment 22 is a lower storage compartment formed by dividing the cold storage space vertically using a partition 50.

[0030] The refrigerator compartment 20 is a storage compartment maintained at a refrigeration temperature range, such as 2 to 5°C, and is equipped with multiple shelves 8. A pull-out container 7, which can be pulled out in a forward and backward direction, is positioned between the bottom shelf 8 and the partition 50. The pull-out container 7 has an upper drawer-type container 7a and a lower container 7b arranged vertically, and a cover 7c rotatably mounted on the front end of the bottom shelf 8. The lower container 7b of the pull-out container 7 is designed to be pulled out in a forward and backward direction from the partition 50 that forms the bottom surface of the refrigerator compartment 20.

[0031] In addition, the vegetable compartment 22 is a storage room that is maintained at a refrigeration temperature range, such as 4 to 7 degrees Celsius, and contains drawer-type storage containers with upper and lower layers.

[0032] like Figure 2 As shown, a refrigerator door 21 is provided at the front opening of the refrigerator compartment 20. Viewed from the front, the refrigerator door 21 is located on the left and right sides (in...) Figure 1 The upper part of the refrigerator body 2 (right side) is rotatably supported by the upper door support part, and the lower part of the left and right sides is rotatably supported by the lower door support part.

[0033] The front opening of the vegetable compartment 22 is opened and closed via a drawer-type vegetable compartment door 23 connected to a guide rail (not shown) and configured to move in the front-back direction. The aforementioned storage container is installed inside the vegetable compartment door 23. Therefore, when the user opens the vegetable compartment door 23, the drawer-type container is pulled out as a single unit along with the vegetable compartment door 23.

[0034] Ice-making chamber 24, first freezer chamber 26, and second freezer chamber 28 are formed within a frozen storage space formed inside a single inner casing 4. A freezer divider 45 divides the frozen storage space vertically, and the second freezer chamber 28 is formed on the lower side of the freezer divider 45. The space formed on the upper side of the freezer divider 45 is further divided horizontally by left and right dividers 46 to form ice-making chamber 24 and first freezer chamber 26.

[0035] The front openings of the ice-making compartment 24, the first freezer compartment 26, and the second freezer compartment 28 are connected to guide parts (not shown) such as pull-out rails and are configured to open and close via drawer-type doors 25, 27, and 29 that can move in the front-back direction. Storage containers are housed in the ice-making compartment 24, the first freezer compartment 26, and the second freezer compartment 28. The storage containers housed in the ice-making compartment 24, the first freezer compartment 26, and the second freezer compartment 28 are connected to the drawer-type doors 25, 27, and 29, and the storage containers move in and out of the ice-making compartment 24, the first freezer compartment 26, and the second freezer compartment 28 in conjunction with the pulling-out operation of the drawer-type doors 25, 27, and 29.

[0036] A first cooler chamber 30 and a first pipe 31 are formed at the rear of the cold storage space (cold storage room 20 and vegetable room 22).

[0037] The first cooler chamber 30 is formed by the space sandwiched between the back of the inner box 4a and the first cooler cover 34, and is located behind the partition 50 that separates the refrigerator compartment 20 and the vegetable compartment 22 vertically. The first cooler chamber 30 houses the first cooler 32 and the first fan 33, and the first fan 33 introduces the air in the first cooler chamber 30, which has been cooled by the first cooler 32, into the first duct 31.

[0038] The first duct 31 is disposed in the space between the back of the inner casing 4a and the duct component 35. Cold air cooled by the first cooler 32 is introduced from the first cooler chamber 30 by the rotation of the first fan 33, flowing from bottom to top, and then blown out of the outlet 36 into the refrigerator compartment 20. After circulating within the refrigerator compartment 20, a portion of the cold air flows into the vegetable compartment 22 from the inlet 38 located on the partition 50. The cold air flowing into the vegetable compartment 22 flows within the vegetable compartment 22 and is then drawn into the first cooler chamber 30 through the suction inlet (not shown), where it is cooled again in the first cooler 32.

[0039] In addition, a second cooler chamber 40 and a second pipe 41 are formed at the rear of the frozen storage space (ice-making chamber 24, first freezer chamber 26 and second freezer chamber 28).

[0040] The second cooler chamber 40 is formed by the space sandwiched between the inner casing back 4a and the second cooler cover 44, and is located behind the freezing partition component 45 and the left and right partition components 46 that separate the ice-making chamber 24, the first freezing chamber 26, and the second freezing chamber 28. The second cooler chamber 40 houses the second cooler 42 and the second fan 43, and the second fan 43 introduces the air cooled by the second cooler 42 from the second cooler chamber 40 into the second channel 41.

[0041] The second pipe 41 is formed inside the second cooler cover 44. The cold air generated in the second cooler 42 is blown into the freezing space through the second pipe 41 from the outlet 47 formed on the back of the freezing storage space. After circulating in the freezing storage space, it returns to the second cooler chamber 40 from the suction port 48 formed at the lower back of the second freezing chamber 28, and is cooled again in the second cooler 42.

[0042] A mechanical compartment 9 is located at the lower rear of the refrigerator body 2. The mechanical compartment 9 houses a compressor 10, a condenser (not shown), and other components. The compressor 10, condenser, first cooler 32, and second cooler 42 constitute a known refrigeration cycle device. The refrigerant compressed by the compressor 10 transforms into a high-temperature, high-pressure gaseous refrigerant, which dissipates heat in the condenser, heat dissipation refrigerant pipes (not shown), and anti-condensation refrigerant pipes 49, thus becoming a liquid refrigerant. The liquid refrigerant flows alternately to the first cooler 32 and the second cooler 42 through pressure-reducing sections such as capillary tubes, generating cold air in each cooler as the refrigerant flows.

[0043] A control board 11 for controlling the refrigerator 1 is provided at the rear end of the upper wall of the refrigerator body 2. The control board 11 has a control unit composed of a microcomputer and a read / write storage unit such as flash memory, and is connected to various devices such as various sensors, compressor 10, first fan 33, and second fan 43.

[0044] The control unit, located on the control board 11, controls all operations of the refrigerator 1, including the speed of the first fan 33 and the second fan 43, and the operating frequency of the compressor 10, based on instructions from the operation panel and detection signals from various sensors.

[0045] (2) Refrigerator body 2

[0046] Next, the structure of the refrigerator body 2 will be explained.

[0047] The inner box 4 is made of a synthetic resin molded in one piece using a vacuum forming machine. It is a box-shaped structure with an inner box back 4a, inner box sides 4b located at the left and right front of the inner box back 4a, inner box top located at the upper front of the inner box back 4a, and inner box bottom located at the lower front of the inner box back 4a, with an opening at the front.

[0048] like Figure 3 , Figure 8 as well as Figure 9 As shown, mounting recesses 4b1 are formed on the front sides of the left and right inner box sides 4b, recessed outward in the width direction of the refrigerator. The mounting recesses 4b1 on the left and right inner box sides 4b are positioned opposite each other in the width direction of the refrigerator, separated by a refrigeration storage space. The front end of the mounting recesses 4b1 is open. Specifically, protrusions 4b2 that protrude inward in the width direction of the refrigerator from the mounting recesses 4b1 are provided on the upper, lower, and rear sides of the mounting recesses 4b1. The front part 55 of the base plate of the partition 50 (described later) can be inserted into the mounting recesses 4b1 through the opening at the front end of the mounting recesses 4b1.

[0049] The outer casing 3 is a steel plate component that forms the outer outline of the refrigerator body 2. The outer casing 3 is box-shaped with an opening at the front, facing the inner casing 4's back surface 4a, left and right inner casing sides 4b, 4b, the inner casing top surface, and the inner casing bottom surface. The outer casing top surface and left and right outer casing sides are formed by bending a long strip of steel plate into a U-shape. The outer casing bottom surface and outer casing back surface are separate components from the outer casing top surface and left and right outer casing sides. A stepped portion for forming the machine compartment 9 is formed by bending the outer casing bottom surface.

[0050] A plate-shaped heat-insulating material 5a, fixed to the outer casing 3, is provided in the heat-insulating region 5 formed between the outer casing 3 and the inner casing 4. The plate-shaped heat-insulating material 5a is a plate-shaped heat-insulating material provided along the component dividing the heat-insulating region 5, and is formed, for example, from vacuum heat-insulating material. In this embodiment, the plate-shaped heat-insulating material 5a is provided along the outer casing 3, but it may also be provided along the inner casing 4.

[0051] In addition, in the heat insulation area 5 of the refrigerator body 2, a heat dissipation refrigerant pipe and an anti-condensation refrigerant pipe 49 are provided in the part where there is no plate-shaped heat insulation material 5a. These pipes connect the first cooler 32 and the second cooler 42 to the compressor 10.

[0052] The heat dissipation refrigerant pipe and the anti-condensation refrigerant pipe 49 constitute part of the refrigerant pipe that allows liquid refrigerant to flow on the high-temperature side before the refrigerant is depressurized in the pressure reducing section. They are embedded in the heat insulation area 5 of the refrigerator body 2 in contact with the outer casing 3. For example, the heat dissipation refrigerant pipe is located on the back, left and right sides, and top of the outer casing 3. The anti-condensation refrigerant pipe 49 is located around the front openings of each of the storage compartments 20, 22, 24, 26, and 28 in the refrigerator body 2, and suppresses condensation around the doors by utilizing the condensation heat of the refrigerant flowing through the anti-condensation refrigerant pipe 49.

[0053] Specifically, such as Figure 1 As shown, the anti-condensation refrigerant pipe 49 is disposed on the left and right side walls (the left side wall in this embodiment) of the refrigerator body 2, passing through the front ends of the left and right side walls and the top wall of the refrigerator body 2, respectively. The anti-condensation refrigerant pipe 49 extends downward along the front end of the right side wall of the refrigerator compartment 20, and bends at approximately a right angle on the left and right sides of the partition 50 before entering the partition 50.

[0054] The anti-condensation refrigerant pipe 49 is configured such that when it enters the partition 50 through the other side of the partition 50, it moves back and forth along the partition 50, bends downward at approximately a right angle on the other side of the partition 50, and extends downward along the front end of the side wall of the vegetable compartment 22 on the other side of the partition 50.

[0055] The anti-condensation refrigerant pipe 49 is configured such that when it enters the insulation partition wall 6 by bending at approximately a right angle on the other side of the insulation partition wall 6, it moves back and forth along the insulation partition wall 6 and the left and right partition members 46. On the other side of the insulation partition wall 6, it bends downward at approximately a right angle and extends downward along the front end of the side wall of the left and right side of the first freezer compartment 26. On the other side of the freezer partition member 45, it bends at approximately a right angle and enters the freezer partition member 45.

[0056] The anti-condensation refrigerant pipe 49 is configured such that, upon entering the freezer compartment 45, it oscillates left and right along the freezer compartment 45, then bends downward at approximately a right angle on the other side of the freezer compartment 45 and extends downward along the front end of the other side wall of the second freezer compartment 28. Furthermore, upon reaching the lower front end of the second freezer compartment 28, the anti-condensation refrigerant pipe 49 bends at approximately a right angle to enter the lower side wall of the second freezer compartment 28, then bends backward in a oscillating manner along the lower side wall of the second freezer compartment 28, and extends backward along the lower end of the right side wall of the refrigerator body 2 to enter the machine compartment 9.

[0057] In addition, in the heat insulation area 5 of the refrigerator body 2, in the area where there is no plate-shaped heat insulation material 5a, there are electrical wiring that connects electrical components provided on the inner or outer side of the refrigerator body 2 to the control board, side wall reinforcement plate 100 (described later), and foamed heat insulation material 5b such as polyurethane foam.

[0058] (3) Separator 50

[0059] Next, mainly based on Figures 2-9 The separator 50 will be described. Furthermore, in... Figure 4 , Figure 7 , Figure 8 as well as Figure 9 In this text, the sheet-like thermal insulation material 5a and the foamed thermal insulation material 5b are omitted.

[0060] like Figure 2 As shown, the partition 50 includes an upper partition component 51 that forms the bottom surface of the refrigerator compartment 20, a lower partition component 52 disposed below the upper partition component 51, a reinforcing component 53, and a front partition panel 54.

[0061] The upper partition 51 is provided across the entire width of the refrigerated storage space formed inside the inner box 4. The upper partition 51 includes a front bottom plate part 55 that forms the front portion of the bottom surface of the refrigerated compartment 20 and a rear bottom plate part 56 that is provided on the rear side of the front bottom plate part 55 and forms the rear portion of the bottom of the refrigerated compartment 20.

[0062] In this embodiment, the front component 55 and the rear component 56 of the base plate are made of different synthetic resin molded bodies, and the front end of the rear component 56 rests on the stepped portion 57 provided at the rear end of the front component 55 (see reference). Figure 6 ).

[0063] like Figure 2 and Figure 3 As shown, the boundary portion BD between the front component 55 and the rear component 56 of the base plate is positioned behind the front end of the lower container 7b when the lower container 7b placed on the partition 50 is retracted. When the user observes the refrigerator compartment 20 from the front, the boundary portion BD is blocked by the lower container 7b.

[0064] The front part of the bottom plate 55 constituting the front portion of the bottom surface of the refrigerator compartment 20 includes: a plate portion 59, which is disposed substantially horizontally in the storage space formed inside the inner box 4; a raised portion 60, which rises upward along the front side of the plate portion 59 across the entire width of the storage space; and a vertical wall portion 58, which is provided along the left and right ends of the plate portion 59 and the raised portion 60 along the side surface 4b of the inner box. That is, a raised portion 60 with a vertical dimension larger than that of the plate portion 59 provided at the rear end of the front part of the bottom plate 55 is provided on the front side of the front part of the bottom plate 55.

[0065] like Figure 4 and Figure 6 As shown, a downwardly protruding front wall 61 for filling is provided at the front of the raised portion 60. The front wall 61 for filling extends in the left and right directions and connects with the vertical wall portions 58 provided at the left and right ends of the raised portion 60. A partition front plate 54 is installed on the front side of the front wall 61 for filling.

[0066] A rear wall 62 of the filling portion protruding downward is provided at the rear of the raised portion 60. The rear wall 62 of the filling portion extends in the left and right directions and connects with the vertical wall portions 58 provided at the left and right ends of the raised portion 60.

[0067] On the lower side of the raised portion 60, a heat-insulating material filling portion 63 extending along the width direction of the refrigerator is formed between the front wall 61 and the rear wall 62 of the filling portion. The heat-insulating material filling portion 63 opens downward, and its opening is closed by the lower partition member 52. The left and right sides of the heat-insulating material filling portion 63 are formed by left and right vertical wall portions 58. It is connected to the heat-insulating area 5 formed between the outer box side and the inner box side 4b through through holes 65 provided in the left and right vertical wall portions 58 and through holes 4b3 provided in the inner box side 4b.

[0068] like Figure 7 As shown, the insulation material filling section 63 is provided with a reinforcing member 53, a temperature detection section 69 for detecting temperature, and a door detection section 70 for detecting the opening and closing of the refrigerator door 21, and is filled with foamed insulation material 5b that is filled in the insulation area 5.

[0069] like Figure 5 As shown, in this embodiment, the through hole 65 is an annular hole without gaps in the circumferential direction. For example... Figure 7 as well as Figure 12 As shown, the through hole 65 has a shape that is approximately the same as the through hole 4b provided on the inner side 4b, and is provided on the vertical wall portion 58 in a manner opposite to each other in the width direction of the refrigerator. The through holes 65 and 4b3 are for inserting the fixing portion 53b of the reinforcing member 53 provided in the heat insulation material filling portion 63. The fixing portion 53b protrudes outward in the width direction of the refrigerator from the vertical wall portion 58 and the inner side 2b (i.e., on the side of the heat insulation area 5 formed between the outer side and the inner side 4b).

[0070] With the fixing part 53b of the reinforcing member 53 inserted into the through holes 65 and 4b3, a gap exists between the through holes 65 and 4b3 and the fixing part 53b. The foamed insulation material 5b flows from the insulation area 5 into the insulation material filling part 63 through this gap. That is, the through holes 65 of the left and right side walls 58 and the through holes 4b3 of the inner box side 4b function as insulation inlets.

[0071] In addition, in this embodiment, heat insulation inlets 65 and 4b3 are provided on the left and right sides, and foamed heat insulation material 5b is filled into the heat insulation material filling part 63 from the left and right sides. However, heat insulation inlets 65 and 4b3 can also be provided on one side, and foamed heat insulation material 5b is filled into the heat insulation material filling part 63 from the left and right sides.

[0072] When heat inlets 65 and 4b3 are provided on the left and right sides, the opening amounts of the heat inlets 65 and 4b3 on the left and the heat inlets 65 and 4b3 on the right can be set to be equal, or the opening amounts can be different.

[0073] When the opening amounts of the left and right insulation inlets 65 and 4b3 are different, it is preferable that the opening amount of the insulation inlets 65 and 4b3 on the left and right sides (right side in this embodiment) of the front side where the anti-condensation refrigerant pipe 49 enters the partition 50 from the refrigerator body 2 is larger than that on the other side (left side in this embodiment). On the left and right sides of the front side where the anti-condensation refrigerant pipe 49 enters the partition 50, in order to prevent the foamed insulation material 5b from leaking out, sometimes a sealing material such as a soft strip to block the gap is provided. Compared with the other side, the foamed insulation material 5b is sometimes difficult to flow. However, by increasing the opening amount of the insulation inlets 65 and 4b3 on the left and right sides, it is also easy to introduce the foamed insulation material 5b from the through holes 65 on the left and right sides, and it is easy to evenly fill the foamed insulation material 5b in the insulation material filling part 63.

[0074] Furthermore, at least a portion of the periphery of the through hole 65 is provided with a protrusion 67 protruding outward in the width direction (left-right direction) of the refrigerator. This protrusion 67 is inserted through the through hole 4b3 on the inner side panel 4b and protrudes into the heat insulation area 5. That is, in this embodiment, the through hole 4b3 provided on the inner side panel 4b functions as an insertion hole for the protrusion 67 to be inserted.

[0075] In the insulation material filling section 63, the electrical wiring 69a connected to the temperature detection section 69 and the electrical wiring 70a connected to the door detection section 70 enter the insulation region 5 formed between the outer side and the inner side 4b through the through holes 65 and 4b3 provided on the left and right sides (e.g., the left side) of the vertical wall section 58 and the inner side of the cabinet 4b, and are connected to the control board 11 through the insulation region 5. That is, the through holes 65 and 4b3 on the left and right sides function as wiring inlets for guiding the electrical wiring 69a and 70a from the refrigerator body 2 to the insulation material filling section 63.

[0076] In addition, such as Figure 4 As shown, in this embodiment, a plurality of through holes 65a and 65b are provided on the left side of the vertical wall portion 58. The opening area of ​​one through hole 65a is larger than that of the other through hole 65b, allowing the fixing portion 53b on the left side of the reinforcing member 53 to be inserted. One through hole 65a serves as a heat insulation inlet through which the foamed heat insulation material 5b flows into the heat insulation material filling portion 63 through the gap between its periphery and the fixing portion 53b. The other through hole 65b is located at a position further forward than the first through hole 65b, allowing the electrical wiring 69a and 70a to pass through, and serves as a wiring inlet for the electrical wiring 69a and 70a to pass through.

[0077] In addition, such as Figure 5 As shown, the vertical wall portion 58 is provided with a hook portion 58a protruding outward in the width direction of the refrigerator and a receiving portion 58b for receiving screws 71. The vertical wall portion 58 is inserted into and housed in the mounting recess 4b1 provided at the front end of the mounting recess 4b1 provided in the inner box 4. The vertical wall portion 58 housed in the mounting recess 4b1 is such that the lower surface of the vertical wall portion 58 is supported by a protrusion 4b2 provided on the lower side of the mounting recess 4b1, and the hook portion 58a is inserted through a locking hole provided in the mounting recess 4b1. The front part of the bottom plate 55 is temporarily fixed to the inner box 4. In this state, the screws 71 are fastened from the heat insulation area 5 side of the inner box side 4b to the receiving portion 58b, thereby fixing it relative to the inner box 4.

[0078] In addition, such as Figure 9As shown, the portion of the vertical wall 58 extending upward from the plate portion 59 has an inclined surface 58c on its upper end, inside the box (inner side in the width direction), which slopes outward in the width direction towards the upper end. When the plate portion 59 is subjected to the load of the stored items and bends downward, the upper end of the vertical wall 58 may deform by tilting inward in the width direction. By providing the inclined surface 58ca in the vertical wall 58, even if the upper end of the vertical wall 58 deforms by tilting inward in the width direction, the upper end of the vertical wall 58 will not protrude from the mounting recess 4b on the inner side 4b of the box, thus maintaining the aesthetics of the box interior.

[0079] Reinforcing component 53 is, for example, a slender rod-shaped component made of metals such as iron, aluminum, or their alloys. Figure 4 as well as Figure 7 As shown, the reinforcing member 53 is housed in the heat insulation material filling part 63 provided in the front part 55 of the base plate, and is configured to connect the opposing parts of the left and right inner box sides 4b.

[0080] like Figure 6 , Figure 10 as well as Figure 11 As shown, the reinforcing member 53 includes a main part 53a extending along the width direction of the refrigerator and a fixing part 53b provided at both ends of the main part 53a and fixing the side wall reinforcing plate 100.

[0081] The main part 53a has a front part 53a1 facing the front-back direction, a lower part 53a2 extending rearward from the lower end of the front part 53a1, and an upper part 53a3 extending rearward from the upper end of the front part 53a1. The ko-shaped opening is provided in a rearward direction.

[0082] The lower part 53a2 of the main part 53a is provided with a receiving part (internal thread) 53a2a for receiving the screw 72 that is fixed from below to separate the lower part 52.

[0083] In addition, such as Figure 11 As shown, an insertion portion 53a3a is provided on the upper portion 53a3 of the main portion 53a, into which a protrusion 63d protruding from the lower surface of the raised portion 60 is inserted into the insulation material filling portion 63. When the reinforcing member 53 is placed in the insulation material filling portion 63, the protrusion 63d is inserted into the insertion portion 53a3a. The insertion portion 53a3a is configured to be longer than the protrusion 63d in the left-right direction. By sliding the reinforcing member 53 to one side in the left-right direction until the protrusion 63d abuts against the edge of the insertion portion 53a3a, the reinforcing member 53 can be positioned in a predetermined position, thereby improving the efficiency of the subsequent screw tightening operation of the screw 72.

[0084] The fixing parts 53b, located at the left and right ends of the main part 53a, protrude into the heat insulation area 5 through the through holes 65 provided in the vertical wall part 58. The fixing parts 53b are provided with a receiving part (internal thread) 53b1 for receiving the screws 73 that are used to fix the side wall reinforcement plate 100.

[0085] like Figure 6 As shown, in the front component 55 of the base plate, a support protrusion 63a is provided between the front wall 61 and the rear wall 62 of the filling portion, protruding from the lower side of the raised portion 60 toward the insulation material filling portion 63. The support protrusion 63a is provided in the front-rear direction in such a way that it contacts the upper part 53a3 of the reinforcing member 53 provided in the insulation material filling portion 63, and the support protrusion 63a supports the raised portion 60 from the lower side to suppress the bending deformation of the raised portion 60.

[0086] The lower partition member 52 closes the opening of the insulation material filling part 63 on the front part 55 of the base plate of the upper partition member 51 from below. The lower partition member 52 has a claw part 52a opposite to the front wall 61 of the filling part and a claw part 52b opposite to the rear wall 62 of the filling part. The claw part 52a engages with the engagement hole 61a provided on the front wall 61 of the filling part, and the claw part 52b is fixed to the upper partition member 51 by engaging with the engagement hole 62a provided on the rear wall 62 of the filling part.

[0087] In addition, such as Figure 6 As shown, the lower partition member 52 is secured from below to the receiving portion 53a2a of the reinforcing member 53. In this embodiment, the lower partition member 52 has an upwardly recessed portion 52c and a cylindrical portion 52d protruding upward from the recess 52c toward the heat insulation material filling portion 63. The screw 73 is inserted through the bottom of the recess 52c and the hollow portion provided in the cylindrical portion 52d to secure it to the receiving portion 53a2a of the reinforcing member 53.

[0088] If screw 73 is fastened to the receiving portion 53a2a, the head of screw 73 will not be received downward from the recess 52c. Additionally, the cylindrical portion 52d abuts against the lower portion 53a2 of the reinforcing member 53. The reinforcing member 53 is held vertically by the support protrusion 63a and the cylindrical portion 52d, restricting its vertical position.

[0089] Furthermore, the reinforcing member 53 can be disposed at any position in the insulation material filling portion 63, but it is preferable to separate the reinforcing member 53 from the front wall 61 and the rear wall 62 of the filling portion in such a way that foamed insulation material 5b is filled in front of and behind the reinforcing member 53. By filling the reinforcing member 53 with foamed insulation material 5b in front of and behind it, the reinforcing effect of the refrigerator body 2 is improved, and the insulation material can be placed between the metal reinforcing member 53 and the air inside and outside the refrigerator, thus suppressing heat leakage.

[0090] The front space 63b filled with foamed thermal insulation material 5b, formed on the front side of the reinforcing member 53, is preferably larger than the rear space 63c filled with foamed thermal insulation material 5b, formed on the rear side of the reinforcing member 53. For example, it is preferable that the length in the front-rear direction from the front wall 61 of the filling portion to the cylindrical portion 52d is longer than the length in the front-rear direction from the cylindrical portion 52d to the rear wall 62 of the filling portion. The length in the front-rear direction from the front wall 61 of the filling portion to the screw 73 is preferably longer than the length in the front-rear direction from the screw 73 to the rear wall 62 of the filling portion. By making the front space 63b larger than the rear space 63c, it is easier to fill the thermal insulation material filling portion 63 with foamed thermal insulation material 5b.

[0091] That is, in order to fill the refrigerator body 2 with foamed insulation material, the refrigerator body 2 is laid down with the front of the refrigerator body 2 facing downwards, and the foaming liquid of the foamed insulation material 5b is injected from the injection hole provided on the back of the outer box 3. Therefore, the closer to the front of the refrigerator body 2, the higher the fluidity of the foaming liquid, and the easier it is to fill the foamed insulation material 5b into the insulation material filling part 63.

[0092] Furthermore, when the raised portion 60 has an inclined portion 60a that becomes thinner towards the rear, it is preferable to arrange the reinforcing member 53 such that at least a portion of the reinforcing member 53 in the longitudinal direction is located in the inclined portion 60a. By arranging the reinforcing member 53 in this way, the thicker portion of the raised portion 60 in the vertical direction can be filled with foamed thermal insulation material 5b, resulting in high thermal insulation and reinforcement effects.

[0093] like Figure 4 as well as Figure 6 As shown, the lower surface of the plate portion 59 located behind the rear wall 62 of the filling portion in the front component 55 of the base plate is provided with left and right protrusions 80, first front and rear protrusions 81 and second front and rear protrusions 82, and the multiple protrusions are arranged in a grid pattern along the left and right direction and the front and rear direction.

[0094] The left and right protruding strips 80 are protruding strips extending in the left and right directions, and multiple of them are provided at intervals in the front and back directions. The left and right protruding strips 80 are provided throughout the entire width of the plate portion 59, and the left and right ends are connected to the vertical wall portion 58.

[0095] The first front and rear protrusions 81 are protrusions that extend in the front-rear direction in a manner that intersects with the left and right protrusions 80, and multiple protrusions are provided at intervals in the left-right direction. The front end of the first front and rear protrusions 81 is connected to the rear wall 62 of the filling part, and the rear end is connected to the left and right protrusions 80 located on the rearmost side.

[0096] The second front and rear protrusions 82 are protrusions that extend in the front and rear direction and are disposed between the adjacent first front and rear protrusions 81. The front end of the second front and rear protrusions 82 is connected to the rear wall 62 of the filling part, and the rear end is connected to the left and right protrusions (the left and right protrusions that are opposite to the rear wall 62 of the filling part) 80 located at the frontmost side.

[0097] (4) Side wall reinforcement plate 100

[0098] like Figure 3 , Figure 7 as well as Figure 8 As shown, the side wall reinforcing plate 100 is disposed in the portion of the heat insulation area 5 filled with foamed heat insulation material 5b, and at least a portion of the side wall reinforcing plate 100 is in contact with the foamed heat insulation material 5b. The side wall reinforcing plate 100 is fixed to the fixing portion 53b of the reinforcing member 53 housed in the heat insulation material filling portion 63 separating the upper part 51 by screws 73. In this embodiment, the fixing portion 53b of the reinforcing member 53 protrudes further outward in the width direction of the refrigerator than the vertical wall portion 58 and the inner side panel 2b, thus forming a gap between the side wall reinforcing plate 100 fixed to the fixing portion 53b and the inner side panel 4b, and foamed heat insulation material 5b is also disposed between the side wall reinforcing plate 100 and the inner side panel 4b.

[0099] The sidewall reinforcing plate 100 is formed by bending a metal plate. Specifically, as shown... Figure 6 as well as Figure 12 As shown, the side wall reinforcement plate 100 has a plate portion 101 disposed on the heat insulation area side of the left and right inner box side 4b, and a rear extension portion 102 extending rearward from the rear end of the plate portion 101.

[0100] The plate portion 101 is approximately rectangular in shape, longer vertically than horizontally, and has a threaded hole 103 and a through hole 104 at its center in the vertical direction. The threaded hole 103 is positioned opposite the fixing portion 53b of the reinforcing member 53 in the left-right direction, through which the screw 73 fastened to the fixing portion 53b is inserted. The through hole 104 is positioned opposite the through hole 65 of the vertical wall portion 58 and a portion of the through hole 4b3 of the inner casing side 4b in the left-right direction, connecting the heat insulation area 5 with the heat insulation material filling portion 63, and inserting a protrusion 67 protruding from the periphery of the through hole 65 of the vertical wall portion 58.

[0101] In addition, the plate portion 101 is provided with a plurality of groove-shaped upper and lower protrusions 108 that extend in the vertical direction above and below the threaded hole 103 and the through hole 104 at intervals in the front-back direction.

[0102] The rear extension 102 extends rearward from the rear end of the central portion in the vertical direction of the plate portion 101. A locking portion 105, bent inward in the width direction of the refrigerator, is provided at the upper and lower ends of the rear extension 102.

[0103] The locking part 105 is configured to clamp the heat insulation area 5 of the mounting recess 4b on the side 4b of the inner box from the top and bottom, thereby restricting the side wall reinforcement plate 100 from rotating in the direction of screw tightening of the screw 73.

[0104] The rear extension 102 is provided with a hook hole 106, a threaded hole 107, and front and rear recessed portions 109. The hook hole 106 is for inserting the hook portion 58a of the vertical wall portion 58 protruding from the inner box side 4b toward the heat insulation area 5, and the rear extension 102 is held between the hook portion 58a and the inner box side 4b. As a result, the rotation of the side wall reinforcing plate 100 in the screw tightening direction of the screw 72 is restricted. That is, in this embodiment, the locking portion 105 and the hook portion 58a provided at the upper and lower ends of the rear extension 102 function as rotation limiting portions that restrict the rotation of the side wall reinforcing plate 100 in the screw tightening direction.

[0105] The threaded hole 107 is for the screw 71 to be inserted into the upright wall portion 58 of the front component 55 of the base plate. The front and rear concave and convex portions 109 are in the shape of grooves extending in the front and rear direction and provided above and below the hook hole 102b. The front end of the front and rear concave and convex portions 109 is bent at approximately a right angle in the vertical direction and connects with the upper and lower concave and convex portions 108.

[0106] (5) Rear component of base plate 56

[0107] The rear component 56 of the base plate is a component formed from synthetic resin into a predetermined shape by injection molding or the like. The rear component 56 is engaged with the rear component 55 of the front component 55 by overlapping its front end, and the rear end is engaged with the cooler cover 34, thus being disposed on the rear side of the front component 55 of the base plate. Thus, the rear component 56 and the front component 55 of the base plate together divide the refrigerator compartment 20 and the vegetable compartment 22 vertically.

[0108] (6) Assembly method of refrigerator body 2

[0109] Next, the assembly method of the refrigerator body 2 in the refrigerator 1 described above will be explained.

[0110] First, a reinforcing member 53 is provided in the heat insulation material filling portion 63 of the front component 55 of the base plate. For example, as Figure 10 As shown, after tilting the reinforcing member 53 and inserting one end of the reinforcing member 53 in the refrigerator width direction through the lower opening of the insulation material filling part 63 into the through hole 65 of the vertical wall part 58, the reinforcing member 53 is rotated with the contact part with the through hole 65 as the fulcrum by moving the other end of the reinforcing member 53 upward, so that the reinforcing member 53 is completely housed in the insulation material filling part 63. Then, the reinforcing member 53 is placed in the insulation material filling part 63 by inserting the other end of the reinforcing member 53 into the through hole 65.

[0111] If the reinforcing member 53 is placed in the heat insulation material filling part 63, the protrusion 63d is inserted into the insertion part 53a3a. Then, the reinforcing member 53 is slid to one side in the left-right direction until the protrusion 63d abuts against the edge of the insertion part 53a3a, thereby placing the reinforcing member 53 in the predetermined position.

[0112] In addition, a temperature detection unit 69 and a door detection unit 70 are installed at predetermined positions within the insulation material filling section 63, and the electrical wiring 69a of the temperature detection unit 69 and the electrical wiring 70a of the door detection unit 70 are routed to the insulation area 5 through the through holes 65 provided on the left and right sides of the vertical wall section 58.

[0113] Then, after closing the lower opening of the insulation material filling part 63 using the lower partition member 52, the screw 72 is fastened to the receiving part 53b1 provided on the reinforcing member 53 from the lower side of the lower partition member 52, thereby fixing the lower partition member 52 to the front part 55 of the base plate and positioning the reinforcing member 53 at the designated position of the insulation material filling part 63.

[0114] Then, the front bottom plate component 55, which is fixed with the reinforcing component 53 and the lower partition component 52, is inserted from the front into the mounting recess 4b provided on the side surface 4b of the inner box. At this time, the hook portion 58a of the vertical wall portion 58 is inserted through the locking hole provided in the mounting recess 4b1 to temporarily fix the front bottom plate component 55 to the inner box 4, and the protrusion 67 and the fixing portion 53b of the reinforcing component 53 are inserted from the inside of the box into the through hole 4b3 provided on the side surface 4b of the inner box, so that the protrusion 67 protrudes towards the heat insulation area 5.

[0115] Furthermore, the locking portion 105 of the side wall reinforcement plate 100 is configured to clamp the mounting recess 4b of the inner box side 4b from the top and bottom, and the hook portion 58a protruding from the inner box side 4b toward the heat insulation space side is inserted into the hook hole 106 of the side wall reinforcement plate 100, thereby temporarily fixing the side wall reinforcement plate 100 to the heat insulation space side in a state along the heat insulation area side of the inner box side 4b.

[0116] Then, screw 73 is passed through the threaded hole 103 of the side wall reinforcement plate 100 and fastened to the receiving part 53b1 of the fixing part 53b provided on the reinforcement member 53, thereby fixing the side wall reinforcement plate 100 to the heat insulation space side of the inner box side 4b.

[0117] In addition, the front part of the base plate 55 is fixed to the inner box 4 by passing the screw 71 through the threaded hole 107 of the side wall reinforcement plate 100 and the threaded hole provided on the side of the inner box 4b and fastening it to the receiving part 58b of the vertical wall part 58.

[0118] Furthermore, before the heat insulation zone 5 is closed, a heat dissipation refrigerant pipe for the refrigerant to flow in the refrigeration cycle device and a condensation-proof refrigerant pipe 49 are arranged, and the electrical wiring 69a of the temperature detection unit 69 and the electrical wiring 70a of the door detection unit 70, which are led out to the heat insulation zone 5 through the through hole 65, are connected to the control board 11 through the heat insulation zone 5.

[0119] Furthermore, by engaging the front end of the inner box 4 with the front end of the outer box 3, and engaging the bottom and back of the outer box 3 with the left, right, and top sides of the outer box 3, the insulation area 5 of the refrigerator body 2 is sealed off except for the injection hole (not shown) of the foam insulation material. In addition, a partition front plate 54 is fixed to the front of the bottom plate front component 55.

[0120] Then, the original liquid of the foamed insulation material is injected into the insulation zone 5 through the injection hole, filling the insulation zone 5 with foamed insulation material 5b. The sidewall reinforcing plate 100 and the screws 73 that fix it to the reinforcing member 53 are thus embedded in the foamed insulation material 5b. Additionally, a portion of the foamed insulation material 5b filled in the insulation zone 5 flows into the insulation material filling section 63 through the through hole 104 of the sidewall reinforcing plate 100, the through hole 4b3 of the inner box side 4b, and the through hole 65 of the vertical wall portion 58, filling the insulation material filling section 63 with foamed insulation material 5b1. Thus, the foamed insulation material 5b connected to the foamed insulation material 5b provided in the insulation zone 5 is disposed in the insulation material filling section 63 of the partition 50.

[0121] (7) Effect

[0122] In the refrigerator 1 of this embodiment, the foamed insulation material 5b1, which is connected to the foamed insulation material 5b provided in the insulation area 5, is provided in the insulation material filling part 63 of the partition body 50. Therefore, it can suppress the bending and twisting of the side wall of the refrigerator body 2 and easily ensure the strength of the refrigerator body 2.

[0123] Furthermore, since the structure of forming a heat insulation material filling part 63 with a downward opening in the front component 55 of the base plate and closing the opening by the lower partition component 52 is adopted, it is easy to manufacture a partition body 50 having a heat insulation material filling part 63 filled with foamed heat insulation material 5b.

[0124] In this embodiment, left and right protrusions 80, first front and rear protrusions 81, and second front and rear protrusions 82 are provided on the lower surface of the plate portion 59. The front and rear protrusions 81 and 82 connecting the rear wall 62 of the filling portion to the left and right protrusions 80 located at the foremost side are arranged more densely than the front and rear protrusions 81 connecting the left and right protrusions 80 to each other. Therefore, it is possible to prevent the rear wall 62 of the filling portion from deforming backward under the filling pressure when the foamed insulation material is filled, and to suppress the defect of the foamed insulation material 5b leaking from the rear wall 62 of the filling portion and the lower partition member 52. In other words, the lower surface of the plate portion 59 of the bottom plate front member 55 is reinforced by the left and right protrusions 80 extending in the left and right direction and the first front and rear protrusions 81 extending in the front and rear direction. Moreover, near the insulation material filling portion 63, in addition to the first front and rear protrusions 81, the second front and rear protrusions 82 extending in the front and rear direction are also applied, thereby suppressing deformation caused by filling pressure.

[0125] Furthermore, in this embodiment, the case where the front end of the second front and rear protrusions 82 is connected to the rear wall 62 of the filling portion, and the rear end is connected to the left and right protrusions 80 located at the foremost side (the left and right protrusions facing the rear wall 62 of the filling portion), has been described. However, the second front and rear protrusions 82 may also be provided in a manner that connects to the left and right protrusions 80 from the second to the third from the front. That is, the second front and rear protrusions 82 may also be provided in a manner that is shorter than the first front and rear protrusions 81 in the front-rear direction. However, the technical significance of resisting the filling pressure of the foamed insulation material caused by the second front and rear protrusions 82 is relatively small on the side of the plate portion 59 of the front member 55 near the rear end. Therefore, it becomes advantageous in terms of manufacturing cost if the second front and rear protrusions 82 are only provided on the side near the front end and not on the side near the rear end.

[0126] In this embodiment, the insulation inlet for introducing the foaming liquid from the insulation area 5 of the refrigerator body 2 to the insulation material filling part 63 is provided in the through hole 65a of the left vertical wall part 58 and the through hole 65 of the right vertical wall part 58. The wiring inlet for introducing the electrical wiring 69a and 70a from the refrigerator body 2 to the insulation material filling part 63 is provided in the through hole 65b of the left vertical wall part 58. The insulation inlet is provided separately from the wiring inlet. Therefore, it is difficult to obstruct the flow of foamed insulation material from the refrigerator body 2 to the insulation material filling part 63 by the electrical wiring 69a and 70a, and it is easy to fill the insulation material filling part 63 with foamed insulation material.

[0127] In this embodiment, at least a portion of the periphery of the through hole 65 provided in the vertical wall portion 58 is provided with a protrusion 67, which is inserted into the through hole 4b3 provided in the inner box side surface 4b provided in the refrigerator body 2. Therefore, when the bottom plate front component 55 is inserted from the front into the mounting recess 4b1 provided in the inner box side surface 4b and temporarily fixed to the inner box 4, the protrusion 67 is supported by the peripheral surface of the inner box side surface 4b, and the bottom plate front component 55 can be positioned in a predetermined position.

[0128] In this embodiment, the reinforcing members 53, which are connected to the side wall reinforcing plates 100 provided on the refrigerator body 2 at both ends, are provided in the heat insulation material filling part 63, so that the bending and twisting of the side wall of the refrigerator body 2 can be further suppressed.

[0129] In addition, by fastening the screw 72 to the receiving portion 53b provided in the reinforcing member 53 from the lower side of the partition member 52, the partition member 52 can be fixed to the front member 55 of the base plate, and the reinforcing member 53 can be positioned at a predetermined position in the heat insulation material filling portion 63.

[0130] In this embodiment, the locking portion 105 and hook portion 58a provided at the upper and lower ends of the rear extension 102 are provided as rotation limiting portions to restrict the side wall reinforcing plate 100 from rotating in the rotation direction of screw fastening. Therefore, when the side wall reinforcing plate 100 is fixed to the fixing portion 53b of the reinforcing member 53 using the screw 73, the side wall reinforcing plate 100 will not rotate, resulting in excellent assembly workability.
