[0008] Hereinafter, a refrigerator 1 according to one embodiment of the present invention will be described with reference to the drawings. Note that 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 and its equivalents as described in the claims.
[0009] In the following explanation, left-right, front-back, and up-down directions refer to the directions when viewing the refrigerator from the front, with the left-right direction corresponding to the width of the refrigerator. Also, unless otherwise specified, right, left, up, down, back, back, and front refer to the position or side when viewing the refrigerator from the front. Furthermore, in the inner box 4 of refrigerator 1, the side facing the storage compartment is referred to as the interior side, and the side facing the outer box 3 via the insulation material is referred to as the insulated area side.
[0010] (1) Configuration of Refrigerator 1 The configuration of refrigerator 1 will be explained with reference to the diagram.
[0011] As shown in Figures 1 and 2, the refrigerator 1 includes a refrigerator body 2 that opens to the front. The refrigerator body 2 comprises an outer box 3 made of steel plate and an inner box 4 made of synthetic resin, and an insulating area 5 is formed between the outer box 3 and the inner box 4 for housing insulating material such as plate-shaped insulating material 5a or foamed insulating material 5b.
[0012] The refrigerator body 2 has an internal space that is divided vertically by an insulating partition wall 6. Above the insulating partition wall 6 is a space containing a refrigerator compartment 20 and a vegetable compartment 22 (hereinafter sometimes referred to as the refrigerated storage space), and below the insulating partition wall 6 is a space containing an ice-making compartment 24, a first freezer compartment 26, and a second freezer compartment 28 (hereinafter sometimes referred to as the frozen storage space).
[0013] The refrigerator compartment 20 is the upper storage compartment formed by dividing the refrigerated storage space inside a single inner box 4 into upper and lower sections by a partition 50. The vegetable compartment 22 is the lower storage compartment formed by dividing the refrigerated storage space into upper and lower sections by a partition 50.
[0014] The interior of the refrigerating chamber 20 is a storage chamber maintained within a refrigerating temperature range, for example, at 2 to 5 °C, and a plurality of placing shelves 8 are provided inside. A drawer container 7 that can be pulled out in the front-rear direction is arranged between the lowermost placing shelf 8 and the partition body 50. The drawer container 7 includes a pull-out upper container 7a and a lower container 7b provided one above the other vertically, and a lid body 7c rotatably provided at the front end of the lowermost placing shelf 8. The lower container 7b of the drawer container 7 is provided so as to be pullable out in the front-rear direction on the partition body 50 that constitutes the bottom surface of the refrigerating chamber 20.
[0015] Also, the interior of the vegetable chamber 22 is a storage chamber maintained within a refrigerating temperature range, for example, at 4 to 7 °C, and vertically two-stage pull-out storage containers are stored inside.
[0016] As shown in FIG. 2, a refrigerating chamber door 21 is provided at the front opening of the refrigerating chamber 20. The refrigerating chamber door 21 is rotatably supported by a refrigerator main body 2 by an upper door support portion at the upper part on one side (the right side in FIG. 1) when viewed from the front, and is rotatably supported by a refrigerator main body 2 by a lower door support portion at the lower part on one side.
[0017] The front opening of the vegetable chamber 22 is opened and closed by a pull-out vegetable chamber door 23 connected to a guiding portion (not shown) such as a pull-out rail and provided so as to be movable in the front-rear direction. The above storage container is attached to the inside of the vegetable chamber door 23. Therefore, when the user opens the vegetable chamber door 23, the pull-out type container is pulled out integrally with the vegetable chamber door 23.
[0018] The ice-making chamber 24, the first freezing chamber 26, and the second freezing chamber 28 are formed within a refrigerating storage space formed inside a single inner box 4. A freezing partition member 45 partitions the refrigerating storage space vertically, and a second freezing chamber 28 is formed below the freezing partition member 45. The space formed above the freezing partition member 45 is further partitioned into left and right by a left-right partition member 46, and the ice-making chamber 24 and the first freezing chamber 26 are formed.
[0019] The front openings of the ice-making compartment 24, the first freezer compartment 26, and the second freezer compartment 28 are opened and closed by retractable doors 25, 27, and 29, which are connected to guide parts (not shown) such as drawer rails and are movable in the front-rear direction. Storage containers are stored in the ice-making compartment 24, the first freezer compartment 26, and the second freezer compartment 28. The storage containers stored in the ice-making compartment 24, the first freezer compartment 26, and the second freezer compartment 28 are connected to the retractable doors 25, 27, and 29 provided in the ice-making compartment 24, the first freezer compartment 26, and the second freezer compartment 28, and each storage container is moved in and out of the ice-making compartment 24, the first freezer compartment 26, and the second freezer compartment 28 in conjunction with the operation of the retractable doors 25, 27, and 29.
[0020] A first cooler chamber 30 and a first duct 31 are formed at the rear of the refrigerated storage space (refrigerator compartment 20 and vegetable compartment 22).
[0021] The first cooler compartment 30 consists of a space sandwiched between the back of the inner box 4a and the first cooler cover 34, and is located behind the partition 50 that vertically separates the refrigerator compartment 20 and the vegetable compartment 22. The first cooler compartment 30 houses the first cooler 32 and the first fan 33, and the first fan 33 introduces the air inside the first cooler compartment 30, which has been cooled by the first cooler 32, into the first duct 31.
[0022] The first duct 31 is located in the space between the back of the inner box 4a and the duct member 35. The cold air cooled by the first cooler 32 is introduced from the first cooler chamber 30 by the rotation of the first fan 33, and flows from bottom to top before being blown into the refrigerator chamber 20 from the outlet 36. After the cold air blown into the refrigerator chamber 20 circulates within the refrigerator chamber 20, a portion of it flows into the vegetable compartment 22 through an inlet 38 provided in the partition 50. The cold air that flows into the vegetable compartment 22 flows through the vegetable compartment 22 and is then drawn in towards the first cooler chamber 30 from an intake port (not shown), where it is cooled again by the first cooler 32.
[0023] Furthermore, a second cooler room 40 and a second duct 41 are formed at the rear of the refrigerated storage space (ice-making room 24, first freezer room 26, and second freezer room 28).
[0024] The second cooler compartment 40 consists of a space sandwiched between the back of the inner box 4a and the second cooler cover 44, and is located behind the freezing partition member 45 and left and right partition members 46 that separate the ice-making compartment 24, the first freezing compartment 26, and the second freezing compartment 28. The second cooler compartment 40 houses the second cooler 42 and the second fan 43, and the second fan 43 introduces the air in the second cooler compartment 40, which has been cooled by the second cooler 42, into the second duct 41.
[0025] The second duct 41 is formed inside the second cooler cover 44. The cold air generated in the second cooler 42 passes through the second duct 41 and is blown into the freezing space from an outlet 47 formed at the rear of the freezing storage space. After circulating through the freezing storage space, it returns to the second cooler chamber 40 from an inlet 48 formed at the lower rear of the second freezing chamber 28, and is cooled again in the second cooler 42.
[0026] A machine room 9 is located at the lower rear of the refrigerator body 2. The machine room 9 houses a compressor 10, a condenser (not shown), and other components. The compressor 10, condenser, first cooler 32, second cooler 42, etc., constitute a well-known refrigeration cycle device. The refrigerant compressed by the compressor 10 changes into a high-temperature, high-pressure gaseous refrigerant, and becomes a liquid refrigerant while releasing heat through the condenser, heat-dissipating refrigerant pipe (not shown), and condensation-preventing refrigerant pipe 49. The liquid refrigerant flows alternately to the first cooler 32 and the second cooler 42 through a pressure-reducing section such as a capillary tube, and cold air is generated in each cooler as the refrigerant flows.
[0027] 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 comprises a control unit consisting of a microcomputer and a read / write storage unit such as flash memory, and various sensors and various devices such as a compressor 10, a first fan 33, and a second fan 43 are connected to it.
[0028] The control unit on the control board 11 controls the overall operation of the refrigerator 1, including the rotation 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.
[0029] (2) Refrigerator body 2 Next, we will explain the configuration of the refrigerator unit 2.
[0030] The inner box 4 is made of a synthetic resin molded body integrally formed by a vacuum forming machine, and has a box shape with an opening at the front, having an inner box back surface 4a, inner box sides 4b provided on the left and right front of the inner box back surface 4a, an inner box top surface provided on the upper front of the inner box back surface 4a, and an inner box bottom surface provided on the lower front of the inner box back surface 4a.
[0031] As shown in Figures 3, 8, and 9, mounting recesses 4b1 are formed on the front sides of the left and right inner box sides 4b, recessing outward in the width direction of the refrigerator. The mounting recesses 4b1 provided on the left and right inner box sides 4b are arranged to face each other in the width direction of the refrigerator, with the refrigerated storage space in between. The front end of the mounting recess 4b1 is open. In other words, protrusions 4b2 that project inward in the width direction of the refrigerator are provided on the upper, lower, and rear sides of the mounting recess 4b1. The bottom plate front member 55 of the partition body 50, which will be described later, can be inserted into the mounting recess 4b1 through the opening provided at the front end of the mounting recess 4b1.
[0032] The outer casing 3 is a steel plate component that forms the outer shell of the refrigerator body 2. The outer casing 3 is a box-shaped structure with an opening at the front, having an outer casing back, left and right outer casing sides, outer casing top, and outer casing bottom that are opposite the inner casing back 4a, left and right inner casing sides 4b, 4b, inner casing top, and inner casing bottom, respectively. The outer casing top and left and right outer casing sides are formed by bending a single long steel plate into a U-shape. The outer casing bottom and outer casing back are components provided separately from the outer casing top and left and right outer casing sides. A stepped portion for forming the machine room 9 is bent and formed on the outer casing bottom.
[0033] A plate-shaped insulating material 5a fixed to the outer box 3 is provided in the insulating region 5 formed between the outer box 3 and the inner box 4. The plate-shaped insulating material 5a is a plate-shaped insulating material provided along the member that partitions the insulating region 5, and is made of, for example, vacuum insulating material. In this embodiment, the plate-shaped insulating material 5a is provided along the outer box 3, but it may also be provided along the inner box 4.
[0034] Furthermore, in the insulated area 5 of the refrigerator body 2, where there is no plate-shaped insulation material 5a, heat-dissipating refrigerant pipes and condensation-preventing refrigerant pipes 49 are provided to connect the first cooler 32 and the second cooler 42 to the compressor 10.
[0035] The heat-dissipating refrigerant pipes and the condensation-preventing refrigerant pipes 49 constitute a part of the high-temperature side refrigerant pipes through which liquid refrigerant flows before being depressurized in the depressurization section, and are embedded in the insulated area 5 of the refrigerator body 2 so as to be in contact with the outer casing 3. For example, the heat-dissipating refrigerant pipes are provided on the back, left and right sides, and top of the outer casing 3. The condensation-preventing refrigerant pipes 49 are arranged around the periphery of the front openings of each storage compartment 20, 22, 24, 26, and 28 provided in the refrigerator body 2, and suppress condensation around the door by the heat of condensation of the refrigerant flowing through the condensation-preventing refrigerant pipes 49.
[0036] Specifically, as shown in Figure 1, the condensation-preventing refrigerant pipe 49 is positioned on the other side wall of the refrigerator compartment 20 (the right side wall in this embodiment), passing through the front ends of one side wall (the left side wall in this embodiment) and the ceiling wall of the refrigerator body 2. The condensation-preventing refrigerant pipe 49 extends downward along the front end of the right side wall of the refrigerator compartment 20, bends at approximately a right angle on the other side of the partition body 50, and enters the partition body 50.
[0037] The condensation-preventing refrigerant pipe 49 enters the partition body 50 by passing through the other left and right sides of the partition body 50, and is positioned to reciprocate back and forth along the partition body 50. On the other left and right sides of the partition body 50, it bends downward at approximately a right angle and extends downward along the front end of the other left and right side wall of the vegetable compartment 22.
[0038] The condensation-preventing refrigerant pipe 49 bends at approximately right angles on the left and right sides of the insulated partition wall 6 and enters the insulated partition wall 6. It is then positioned to reciprocate from side to side along the insulated partition wall 6 and the left and right partition members 46. On the left and right sides of the insulated partition wall 6, it bends downward at approximately right angles and extends downward along the front end of the left and right side walls of the first freezer chamber 26. On the left and right sides of the freezer partition member 45, it bends at approximately right angles and enters the freezer partition member 45.
[0039] When the condensation-preventing refrigerant pipe 49 enters the freezer partition member 45, it is positioned to reciprocate from side to side along the freezer partition member 45, and then bends downward at approximately a right angle on the other side of the freezer partition member 45, extending downward along the front end of the other side wall of the second freezer compartment 28. When the condensation-preventing refrigerant pipe 49 reaches the lower front end of the second freezer compartment 28, it bends at approximately a right angle and enters the lower side wall of the second freezer compartment 28, bends backward to reciprocate from side to side along the lower side wall of the second freezer compartment 28, extends backward along the lower end of the right side wall of the refrigerator body 2, and enters the machine room 9.
[0040] Furthermore, in the insulated area 5 of the refrigerator body 2, where plate-shaped insulation material 5a is not present, foamed insulation material 5b such as polyurethane foam is provided along with electrical wiring that electrically connects electrical components located on the inside or outside of the refrigerator body 2 to the control board, and side wall reinforcing plates 100, which will be described later.
[0041] (3) Partition 50 Next, the partition body 50 will be explained mainly based on Figures 2 to 9. Note that in Figures 4, 7, 8, and 9, the plate-shaped insulation material 5a and the foamed insulation material 5b are omitted from the diagram.
[0042] As shown in Figure 2, the partition 50 comprises an upper partition member 51 that forms the bottom surface of the refrigerator compartment 20, a lower partition member 52 provided below the upper partition member 51, a reinforcing member 53, and a front partition plate 54.
[0043] The upper partition member 51 is provided across the entire width of the refrigerated storage space formed inside the inner box 4. The upper partition member 51 comprises a front bottom plate member 55 that constitutes the front part of the bottom surface of the refrigerated compartment 20, and a rear bottom plate member 56 that is provided behind the front bottom plate member 55 and constitutes the rear part of the bottom of the refrigerated compartment 20.
[0044] In this embodiment, the front base plate member 55 and the rear base plate member 56 are made of separate synthetic resin molded bodies, and the front end of the rear base plate member 56 is placed on a stepped portion 57 (see Figure 6) provided on the rear end of the front base plate member 55.
[0045] As shown in Figures 2 and 3, the boundary BD between the front bottom plate member 55 and the rear bottom plate member 56 is positioned behind the front end of the lower container 7b when the lower container 7b, which is placed on the partition body 50, is stored in the rearward position, so that the boundary BD is hidden by the lower container 7b when the user looks at the refrigerator compartment 20 from the front.
[0046] The front bottom plate member 55, which constitutes the front part of the bottom surface of the refrigerator compartment 20, comprises a plate portion 59 positioned substantially horizontally in the storage space formed inside the inner box 4, a raised portion 60 that rises upward across the entire width of the storage space on the front side of the plate portion 59, and vertical wall portions 58 provided along the inner box sides 4b at both the left and right ends of the plate portion 59 and the raised portion 60. In other words, the front of the front bottom plate member 55 is provided with a raised portion 60 that is larger in the vertical direction than the plate portion 59 provided at the rear end of the front bottom plate member 55.
[0047] As shown in Figures 4 and 6, a filling section front wall 61 that protrudes downward is provided at the front of the raised section 60. The filling section front wall 61 extends in the left-right direction and is connected to vertical wall sections 58 provided at both the left and right ends of the raised section 60. A partition front plate 54 is attached to the front side of the filling section front wall 61.
[0048] A rear wall 62 of the filling section is provided at the rear of the raised section 60, projecting downward. The rear wall 62 of the filling section extends in the left-right direction and is connected to vertical wall sections 58 provided at both the left and right ends of the raised section 60.
[0049] Below the raised portion 60, an insulating material filling portion 63 is formed between the front wall 61 and the rear wall 62 of the filling portion, extending in the width direction of the refrigerator. The insulating material filling portion 63 opens downward, and this opening is closed by the lower partition member 52. The left and right sides of the insulating material filling portion 63 are composed of left and right vertical wall portions 58. Through holes 65 provided in the left and right vertical wall portions 58 and through holes 4b3 provided in the inner box side surface 4b, the insulating region 5 formed between the outer box side surface and the inner box side surface 4b is connected.
[0050] As shown in Figure 7, the insulation material filling section 63 is provided with a reinforcing member 53, a temperature detection unit 69 for detecting temperature, and a door detection unit 70 for detecting the opening and closing of the refrigerator door 21, and is filled with foamed insulation material 5b to fill the insulation area 5.
[0051] As shown in Figure 5, in this embodiment, the through hole 65 is an annular hole without a break in the circumferential direction. As shown in Figures 7 and 12, the through hole 65 has substantially the same shape as the through hole 4b3 provided in the inner box side surface 4b, and is provided in the vertical wall portion 58 so as to face the refrigerator width direction. The fixing portion 53b of the reinforcing member 53 provided in the insulation material filling portion 63 is inserted into the through holes 65 and 4b3, and the fixing portion 53b protrudes outward in the refrigerator width direction from the vertical wall portion 58 and the inner box side surface 2b (i.e., towards the insulation region 5 formed between the outer box side surface and the inner box side surface 4b).
[0052] With the fixing portion 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 portion 53b, allowing the foamed insulation material 5b to flow from the insulation area 5 to the insulation material filling section 63 through this gap. In other words, the through holes 65 in the vertical wall sections 58 on both the left and right sides and the through holes 4b3 in the inner box side surface 4b function as insulation inlets.
[0053] In this embodiment, insulation inlets 65 and 4b3 are provided on both the left and right sides, so that the foamed insulation material 5b is filled into the insulation material filling section 63 from both the left and right sides. However, an insulation inlet 65 or 4b3 may be provided on only one side, so that the foamed insulation material 5b is filled into the insulation material filling section 63 from only one side.
[0054] When insulation openings 65 and 4b3 are provided on both the left and right sides, the opening amounts of the insulation openings 65 and 4b3 on the left side and the insulation openings 65 and 4b3 on the right side may be set to be the same, or they may be set to be different.
[0055] When the opening amounts of the left and right insulation inlets 65 and 4b3 are different, it is preferable to make the opening amount of the insulation inlet 65 and 4b3 on one side (the right side in this embodiment) through which the condensation-preventing refrigerant pipe 49 enters from the refrigerator body 2 to the front of the partition body 50 larger than the opening amount of the insulation inlet 65 and 4b3 on the other side (the left side in this embodiment). On one side through which the condensation-preventing refrigerant pipe 49 enters to the front of the partition body 50, a sealing material such as soft tape may be provided to seal the gap to prevent the foamed insulation material 5b from leaking out, and the foamed insulation material 5b may not flow as easily on this side. However, by making the opening amount of the insulation inlet 65 and 4b3 larger on one side, the foamed insulation material 5b can be more easily introduced from the through-hole 65 on that side, and the foamed insulation material 5b can be more easily filled evenly into the insulation material filling section 63.
[0056] Furthermore, at least a portion of the periphery of the through hole 65 is provided with a projection 67 that protrudes outward in the width direction of the refrigerator (outward in the left-right direction). This projection 67 is inserted through the through hole 4b3 in the inner box side surface 4b and protrudes into the heat insulating area 5. In other words, in this embodiment, the through hole 4b3 provided in the inner box side surface 4b functions as an insertion hole into which the projection 67 is inserted.
[0057] 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 box side and the inner box side 4b through through holes 65 and 4b3 provided in the vertical wall section 58 and the inner box side surface 4b on one side (for example, the left side), and are connected to the control board 11 through the insulation region 5. In other words, the through holes 65 and 4b3 on one side (left or right) function as wiring entry points for introducing the electrical wiring 69a and 70a from the refrigerator body 2 to the insulation material filling section 63.
[0058] As shown in Figure 4, in this embodiment, the left vertical wall portion 58 is provided with multiple through holes 65a and 65b. One through hole 65a has a larger opening area than the other through hole 65b, and the left fixing portion 53b of the reinforcing member 53 is inserted into it. One through hole 65a functions as an insulation inlet through which foamed insulation material 5b flows into the insulation material filling portion 63 via the gap between its periphery and the fixing portion 53b. The other through hole 65b is located in front of the first through hole 65b, and electrical wiring 69a and 70a are inserted through it, functioning as a wiring inlet for inserting the electrical wiring 69a and 70a.
[0059] Furthermore, as shown in Figure 5, the vertical wall portion 58 is provided with a hook portion 58a that protrudes outward in the width direction of the refrigerator and a receiving portion 58b that receives a screw 71. The vertical wall portion 58 is inserted through the opening at the front end of the mounting recess 4b1 provided in the inner box 4 and housed in the mounting recess 4b1. When the vertical wall portion 58 is housed in the mounting recess 4b1, the lower surface of the vertical wall portion 58 is supported by a projection 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, temporarily fixing the bottom plate front member 55 to the inner box 4. In this state, the screw 71 is fastened to the receiving portion 58b from the heat insulating area 5 side of the inner box side 4b, thereby fixing it to the inner box 4.
[0060] As shown in Figure 9, the portion of the vertical wall 58 that extends upward from the plate portion 59 has an inclined surface 58c on the inside (inward in the width direction) of its upper end, which slopes outward in the width direction as it approaches the upper end. When the plate portion 59 bends downward under the load of stored goods, the upper end of the vertical wall 58 may deform to tilt inward in the width direction. By providing the inclined surface 58ca on the vertical wall 58, even if the upper end of the vertical wall 58 deforms to tilt inward in the width direction, the upper end of the vertical wall 58 will not protrude from the mounting recess 4b1 of the inner box side surface 4b, thus maintaining a good aesthetic appearance inside the storage unit.
[0061] The reinforcing member 53 is a long, slender rod-shaped member made of a metal such as iron, aluminum, or an alloy thereof. As shown in Figures 4 and 7, the reinforcing member 53 is housed in the heat insulation filling section 63 provided in the front bottom plate member 55 and is positioned to connect the opposing portions of the left and right inner box sides 4b.
[0062] As shown in Figures 6, 10, and 11, the reinforcing member 53 comprises a main portion 53a extending in the width direction of the refrigerator and fixing portions 53b provided at both ends of the main portion 53a to which the side wall reinforcing plate 100 is fixed.
[0063] The main part 53a comprises a front portion 53a1 facing in the front-rear direction, a lower portion 53a2 extending rearward from the lower end of the front portion 53a1, and an upper portion 53a3 extending rearward from the upper end of the front portion 53a1, with a U-shaped opening facing rearward.
[0064] The lower surface portion 53a2 of the main part 53a is provided with a receiving portion (female thread) 53a2a for receiving a screw 72 that fixes the lower partition member 52 from below.
[0065] Furthermore, as shown in Figure 11, the upper surface portion 53a3 of the main portion 53a is provided with an insertion portion 53a3a into which a projection 63d protruding from the lower surface of the raised portion 60 into the heat insulation filling portion 63 is inserted. When the reinforcing member 53 is placed in the heat insulation filling portion 63, the projection 63d is inserted into the insertion portion 53a3a. The insertion portion 53a3a is provided to be longer in the left-right direction than the projection 63d, and by sliding the reinforcing member 53 to one side in the left-right direction until the projection 63d abuts against the edge of the insertion portion 53a3a, the reinforcing member 53 can be positioned in a predetermined location, thereby improving the efficiency of the subsequent screw fastening work of the screws 72.
[0066] The fixing portions 53b provided at both the left and right ends of the main portion 53a protrude into the heat-insulating area 5 through through holes 65 provided in the vertical wall portion 58. The fixing portions 53b are provided with receiving portions (female threads) 53b1 for receiving screws 73 that fix the side wall reinforcing plate 100.
[0067] As shown in Figure 6, the front member 55 of the bottom plate is provided with a support ridge 63a that protrudes from below the raised portion 60 into the insulation material filling portion 63 between the front wall 61 and the rear wall 62 of the filling portion. The support ridge 63a is provided along the front-rear direction so as to contact the upper surface portion 53a3 of the reinforcing member 53 provided in the insulation material filling portion 63. The support ridge 63a supports the raised portion 60 from below and suppresses the bending deformation of the raised portion 60.
[0068] The lower partition member 52 closes the opening of the insulation material filling section 63 provided in the bottom plate front member 55 of the upper partition member 51 from below. The lower partition member 52 is provided with a claw portion 52a at a position facing the front wall 61 of the filling section and a claw portion 52b at a position facing the rear wall 62 of the filling section. The claw portion 52a engages with an engagement hole 61a provided in the front wall 61 of the filling section, and the claw portion 52b engages with an engagement hole 62a provided in the rear wall 62 of the filling section, thereby fixing it to the upper partition member 51.
[0069] Furthermore, as shown in Figure 6, the lower partition member 52 is fixed by screws 73 fastened from below to the receiving portion 53a2a of the reinforcing member 53. In this embodiment, the lower partition member 52 includes a recessed portion 52c that is recessed upward and a cylindrical portion 52d that protrudes upward from the recessed portion 52c toward the heat insulation filling portion 63. Screws 73 are inserted through the hollow portions provided in the bottom of the recessed portion 52c and the cylindrical portion 52d and fastened to the receiving portion 53a2a of the reinforcing member 53.
[0070] When the screw 73 is fastened to the receiving portion 53a2a, the head of the screw 73 is housed without protruding downward from the recess 52c. Also, the cylindrical portion 52d abuts against the lower surface portion 53a2 of the reinforcing member 53. The reinforcing member 53 is sandwiched vertically between the support projection 63a and the cylindrical portion 52d, and its vertical position is restricted.
[0071] The reinforcing member 53 can be placed at any position in the insulation material filling section 63, but it is preferable to place the reinforcing member 53 in the insulation material filling section 63 away from the front wall 61 and rear wall 62 of the filling section so that foamed insulation material 5b is filled in front of and behind the reinforcing member 53. Filling the front of and behind the reinforcing member 53 with foamed insulation material 5b enhances the reinforcing effect of the refrigerator body 2, and also allows for the interposition of insulation material between the metal reinforcing member 53 and the air inside and outside the refrigerator, thereby suppressing heat leakage.
[0072] It is preferable that the front space 63b, which is filled with foamed insulation material 5b formed on the front side of the reinforcing member 53, is larger than the rear space 63c, which is filled with foamed 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 section to the cylindrical section 52d is longer than the length in the front-rear direction from the cylindrical section 52d to the rear wall 62 of the filling section. It is also preferable that the length in the front-rear direction from the front wall 61 of the filling section to the screw 73 is longer than the length in the front-rear direction from the screw 73 to the rear wall 62 of the filling section. By making the front space 63b larger than the rear space 63c, it becomes easier to fill the insulation material filling section 63 with foamed insulation material 5b.
[0073] In other words, normally, to fill the refrigerator body 2 with foam insulation, the refrigerator body 2 is tilted so that the front of the refrigerator body 2 faces downwards, and the foaming liquid of the foam insulation material 5b is injected through the injection hole provided on the back of the outer box 3. As a result, the fluidity of the foaming liquid is higher towards the front of the refrigerator body 2, making it easier for the foam insulation material 5b to be filled into the insulation material filling section 63.
[0074] Furthermore, if the raised portion 60 has an inclined portion 60a where the thickness decreases towards the rear, it is preferable to position the reinforcing member 53 such that at least a portion of the reinforcing member 53 in the front-rear direction is located on the inclined portion 60a. By positioning the reinforcing member 53 in this way, the foamed insulation material 5b can be filled into the areas of the raised portion 60 that have greater thickness in the vertical direction, thereby obtaining high insulation and reinforcement effects.
[0075] As shown in Figures 4 and 6, the lower surface of the plate portion 59 provided behind the rear wall 62 of the filling portion in the bottom plate front member 55 is provided with left and right protrusions 80, a first front and rear protrusion 81, and a second front and rear protrusion 82, and the multiple protrusions are arranged in a grid pattern along the left and right and front and rear directions.
[0076] The left and right protrusions 80 are protrusions that extend in the left-right direction and are provided in multiples at intervals in the front-rear direction. The left and right protrusions 80 are provided across the entire width of the plate portion 59, and both left and right ends are connected to the vertical wall portion 58.
[0077] The first front and rear protrusions 81 are protrusions that extend in the front-rear direction so as to intersect 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 section, and the rear end is connected to the left and right protrusions 80 that are located at the rearmost position.
[0078] The second front and rear protrusions 82 are protrusions that extend in the front-rear direction and are provided between the left and right 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 section, and the rear end is connected to the left and right protrusions 80 (left and right protrusions that face the rear wall 62 of the filling section in the front and rear directions) that are located at the foremost end.
[0079] (4) Side wall reinforcing plate 100 As shown in Figures 3, 7, and 8, the side wall reinforcing plate 100 is provided in the portion of the insulation area 5 filled with foamed insulation material 5b, and at least a part of the side wall reinforcing plate 100 is in contact with the foamed insulation material 5b. The side wall reinforcing plate 100 is fixed by screws 73 to the fixing portion 53b of the reinforcing member 53 housed in the insulation material filling portion 63 of the partition upper side member 51. In this embodiment, since the fixing portion 53b of the reinforcing member 53 protrudes outward in the refrigerator width direction from the vertical wall portion 58 and the inner box side surface 2b, a gap is formed between the side wall reinforcing plate 100 fixed to the fixing portion 53b and the inner box side surface 4b, and foamed insulation material 5b is also provided between the side wall reinforcing plate 100 and the inner box side surface 4b.
[0080] The side wall reinforcing plate 100 is formed by bending a metal plate. Specifically, as shown in Figures 6 and 12, the side wall reinforcing plate 100 comprises a plate portion 101 provided on the heat insulation area side of the left and right inner box sides 4b, and a rear extension portion 102 extending rearward from the rear end of the plate portion 101.
[0081] The plate portion 101 has a roughly rectangular shape, which is longer in the vertical direction than in the front-to-back direction, and a screw hole 103 and a through hole 104 are provided in the center in the vertical direction. The screw hole 103 is provided in a position opposite to the fixing portion 53b of the reinforcing member 53 in the left-right direction, and a screw 73 that is fastened to the fixing portion 53b is inserted through it. The through hole 104 is provided so as to be opposite to a part of the through hole 65 of the vertical wall portion 58 and the through hole 4b3 of the inner box side surface 4b in the left-right direction, and connects the heat insulation area 5 and the heat insulation material filling portion 63, and a protruding portion 67 that protrudes from the periphery of the through hole 65 of the vertical wall portion 58 is inserted into it.
[0082] Furthermore, the plate portion 101 has multiple upper and lower groove-shaped protrusions 108 extending vertically above and below the screw holes 103 and through holes 104, spaced apart in the front-to-back direction.
[0083] The rear extension 102 extends rearward from the rear end of the vertically central part of the plate portion 101. Locking portions 105, which are bent inward in the width direction of the refrigerator, are provided at the upper and lower ends of the rear extension 102.
[0084] The locking portion 105 is positioned to sandwich the heat insulating area 5 side of the mounting recess 4b1 provided on the inner box side surface 4b from above and below, and restricts the rotation of the side wall reinforcing plate 100 in the rotational direction of screw tightening of the screw 73.
[0085] The extension portion 102 is provided with a hook hole 106, a screw hole 107, and front and rear protrusions 109. The hook portion 58a of the vertical wall portion 58 that protrudes from the inner box side surface 4b toward the heat insulation area 5 is inserted into the hook hole 106, and the extension portion 102 is held between the hook portion 58a and the inner box side surface 4b. This restricts the rotation of the side wall reinforcing plate 100 in the rotational direction of screw tightening of the screw 72. In other words, in this embodiment, the locking portion 105 and the hook portion 58a provided at the upper and lower ends of the extension portion 102 function as rotation restrictors that restrict the rotation of the side wall reinforcing plate 100 in the rotational direction of screw tightening.
[0086] The screw hole 107 is through which a screw 71 is inserted to fasten to the vertical wall portion 58 of the front member 55 of the bottom plate. The front and rear protrusions 109 have a groove shape that extends in the front-rear direction and are provided above and below the hook hole 102b, and the front end of the front and rear protrusions 109 is bent at approximately a right angle in the vertical direction and connected to the upper and lower protrusions 108.
[0087] (5) Rear base plate member 56 The rear base plate member 56 is a component molded into a predetermined shape from synthetic resin by injection molding or the like. The rear base plate member 56 is positioned behind the front base plate member 55, with its leading edge overlapping and engaging with the rear end of the front base plate member 55, and its rear end engaging with the cooler cover 34. As a result, the rear base plate member 56, together with the front base plate member 55, partitions the refrigerator compartment 20 and the vegetable compartment 22 vertically.
[0088] (6) Assembly method for refrigerator unit 2 Next, we will explain how to assemble the refrigerator body 2 in the refrigerator 1 described above.
[0089] First, a reinforcing member 53 is provided in the insulation material filling section 63 of the bottom plate front member 55. For example, as shown in Figure 10, the reinforcing member 53 is tilted and one end of the reinforcing member 53 in the refrigerator width direction is inserted from the lower opening of the insulation material filling section 63 into the through hole 65 of the vertical wall section 58. Then, the reinforcing member 53 is rotated using the contact point with the through hole 65 as a pivot point so that the other end of the reinforcing member 53 moves upward, thereby housing the entire reinforcing member 53 inside the insulation material filling section 63. After that, the other end of the reinforcing member 53 is inserted into the through hole 65 to provide the reinforcing member 53 in the insulation material filling section 63.
[0090] When the reinforcing member 53 is placed in the heat insulation filling section 63, the projection 63d is inserted into the insertion section 53a3a. Then, the reinforcing member 53 is slid to one side in the left-right direction until the projection 63d contacts the edge of the insertion section 53a3a, thereby positioning the reinforcing member 53 in the predetermined position.
[0091] Furthermore, a temperature detection unit 69 and a door detection unit 70 are provided 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 through holes 65 provided in the vertical wall section 58 on one side (left or right).
[0092] Then, after closing the lower opening of the insulation material filling section 63 with the lower partition member 52, the lower partition member 52 is fixed to the front bottom plate member 55 by fastening a screw 72 from the lower side of the lower partition member 52 to a receiving portion 53b1 provided on the reinforcing member 53, and the reinforcing member 53 is positioned in a predetermined location in the insulation material filling section 63.
[0093] Then, the bottom plate front member 55, to which the reinforcing member 53 and the lower partition member 52 are fixed, is inserted from the front into the mounting recess 4b1 provided on the inner box side 4b. 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 bottom plate front member 55 to the inner box 4, and the protruding portion 67 and the fixing portion 53b of the reinforcing member 53 are inserted from the inside of the box into the through hole 4b3 provided on the inner box side 4b to make the protruding portion 67 protrude toward the heat insulating area 5.
[0094] Then, the locking portion 105 of the side wall reinforcement plate 100 is positioned to sandwich the mounting recess 4b1 of the inner box side surface 4b from above and below, and the hook portion 58a that protrudes from the inner box side surface 4b toward the insulation space is inserted through the hook hole 106 of the side wall reinforcement plate 100, thereby temporarily fixing the side wall reinforcement plate 100 to the insulation space side while aligned with the insulation area side of the inner box side surface 4b.
[0095] Subsequently, the side wall reinforcing plate 100 is fixed to the heat insulating space side of the inner box side 4b by passing screws 73 through the screw holes 103 of the side wall reinforcing plate 100 and fastening them to the receiving portion 53b1 provided on the fixing portion 53b of the reinforcing member 53.
[0096] Furthermore, the bottom plate front member 55 is fixed to the inner box 4 by passing screws 71 through the screw holes 107 in the side wall reinforcing plate 100 and the screw holes provided on the inner box side surface 4b and fastening them to the receiving portion 58b of the vertical wall portion 58.
[0097] Then, before closing the insulation area 5, refrigerant pipes such as the heat-dissipating refrigerant pipes and condensation-preventing refrigerant pipes 49 through which the refrigerant in the refrigeration cycle device flows are installed, and the electrical wiring 69a of the temperature detection unit 69 and the electrical wiring 70a of the door detection unit 70, which have been brought out into the insulation area 5 through the through hole 65, are connected to the control board 11 through the insulation area 5.
[0098] Then, the front end of the inner box 4 is engaged with the front end of the outer box 3, and the bottom and back surfaces of the outer box 3 are engaged with the left and right sides and top surfaces of the outer box 3, thereby closing the insulation area 5 of the refrigerator body 2 except for the injection holes (not shown) for the foam insulation material. In addition, the partition front plate 54 is fixed to the front surface of the bottom plate front member 55.
[0099] Then, the raw foam insulation material is injected into the insulation area 5 through the injection hole, filling the insulation area 5 with foam insulation material 5b, thereby embedding the side wall reinforcing plate 100 and the screws 73 that fix it to the reinforcing member 53 into the foam insulation material 5b. In addition, a portion of the foam insulation material 5b that is filled into the insulation area 5 flows into the insulation material filling section 63 through the through hole 104 in the side wall reinforcing plate 100, the through hole 4b3 in the inner box side surface 4b, and the through hole 65 in the vertical wall section 58, and the foam insulation material 5b1 is also filled into the insulation material filling section 63. As a result, foam insulation material 5b connected to the foam insulation material 5b provided in the insulation area 5 is provided in the insulation material filling section 63 of the partition body 50.
[0100] (7) Effects In the refrigerator 1 of this embodiment, a foamed insulation material 5b1 connected to a foamed insulation material 5b provided in the insulation area 5 is provided in the insulation material filling section 63 of the partition body 50. This suppresses bending and twisting of the side walls of the refrigerator body 2, making it easier to ensure the strength of the refrigerator body 2.
[0101] Furthermore, since the bottom plate front member 55 has a heat insulation material filling section 63 that opens downward and the opening is closed by the lower partition member 52, the partition body 50 equipped with a heat insulation material filling section 63 into which foamed heat insulation material 5b is filled can be easily manufactured.
[0102] In this embodiment, left and right protrusions 80, a first front and rear protrusion 81, and a second front and rear protrusion 82 are provided on the lower surface of the plate portion 59. The front and rear protrusions 81 and 82, which connect the rear wall 62 of the filling portion with the left and right protrusions 80 located at the very front, are provided more densely than the front and rear protrusions 81, which connect the left and right protrusions 80 with each other. Therefore, it is possible to prevent the rear wall 62 of the filling portion from deforming and collapsing backward due to the filling pressure when the foam insulation material is filled, and to suppress the problem of foam insulation material 5b leaking out from between 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 left and right protrusions 80 extending in the left-right direction and first front and rear protrusions 81 extending in the front-rear direction. Furthermore, in a position close to the insulation material filling portion 63, a second front and rear protrusion 82 extending in the front-rear direction is added in addition to the first front and rear protrusions 81 to suppress deformation due to filling pressure.
[0103] In this embodiment, the front end of the second front and rear protrusions 82 is connected to the rear wall 62 of the filling section, and the rear end is connected to the left and right protrusions 80 that are located furthest forward (left and right protrusions that face the rear wall 62 of the filling section in the front and rear directions). However, the second front and rear protrusions 82 may also be provided so as to be connected to the left and right protrusions 80 from the second one onwards. In other words, the second front and rear protrusions 82 may be shorter in the front-rear direction than the first front and rear protrusions 81. However, in the plate portion 59 of the front bottom plate member 55, the technical significance of the second front and rear protrusions 82 in resisting the filling pressure of the foamed insulation material is relatively small on the side closer to the rear end. Therefore, it is advantageous in terms of manufacturing costs, etc., to provide the second front and rear protrusions 82 only on the side closer to the front end and not on the side closer to the rear end.
[0104] In this embodiment, insulation inlets for introducing the foaming liquid from the insulation area 5 of the refrigerator body 2 to the insulation material filling section 63 are provided in through-holes 65a in the left vertical wall section 58 and 65 in the right vertical wall section 58, and wiring inlets for introducing electrical wiring 69a and 70a from the refrigerator body 2 side to the insulation material filling section 63 are provided in through-hole 65b in the left vertical wall section 58. Since insulation inlets are provided separately from the wiring inlets, the flow of foaming insulation material from the refrigerator body 2 side to the insulation material filling section 63 is less likely to be obstructed by the electrical wiring 69a and 70a, making it easier to fill the insulation material filling section 63 with foaming insulation material.
[0105] In this embodiment, a projection 67 is provided on at least a portion of the periphery of a through hole 65 provided in the vertical wall portion 58, and the projection 67 is inserted into a through hole 4b3 in the inner box side surface 4b provided on the refrigerator body 2 side. Therefore, when the bottom plate front member 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 projection 67 is supported by the circumferential surface of the inner box side surface 4b, and the bottom plate front member 55 can be positioned in a predetermined location.
[0106] In this embodiment, since the reinforcing members 53, whose left and right ends are connected to the side wall reinforcing plates 100 provided on the refrigerator body 2, are provided in the insulation material filling section 63, bending and twisting of the side walls of the refrigerator body 2 can be further suppressed.
[0107] Furthermore, by fastening a screw 72 from the lower side of the partition lower member 52 to a receiving portion 53b2 provided on the reinforcing member 53, the partition lower member 52 can be fixed to the bottom plate front member 55, and the reinforcing member 53 can be positioned in a predetermined location in the heat insulation material filling section 63.
[0108] In this embodiment, the locking portion 105 and hook portion 58a provided at the upper and lower ends of the extension portion 102 are provided as rotation restricting portions that restrict the rotation of the side wall reinforcing plate 100 in the direction of screw tightening. As a result, when the side wall reinforcing plate 100 is fixed to the fixing portion 53b of the reinforcing member 53 with screws 73, the side wall reinforcing plate 100 does not rotate, resulting in excellent assembly workability.
