Description
Technical Field
The present invention relates to a refrigerator for cooling and storing foods in a storage compartment and a method of manufacturing the same, and more particularly, to a refrigerator having a heat insulating wall for partitioning a storage compartment and a method of manufacturing the same.
Background
A general refrigerator includes a plurality of storage compartments having different internal temperatures, and a heat insulating wall filled with a heat insulating material is disposed between the storage compartments.
Referring to fig. 8, a structure for partitioning each storage room in the related art described in patent document 1(JP laid-open publication No. 2018-179407) is described. Fig. 8 is an exploded perspective view illustrating a related art refrigerator 1100. The refrigerator 1100 includes an insulated cabinet 1101, and a storage compartment is formed inside the insulated cabinet 1101.
The heat-insulating box 1101 includes an outer box 1102, an inner box 1103 disposed inside the outer box 1102, and a heat-insulating material 1104, and the heat-insulating material 1104 is foamed and filled between the outer box 1102 and the inner box 1103. The storage compartments formed inside the heat insulating box 1101 include a refrigerating compartment 1105, a freezing compartment 1106, and a vegetable compartment 1107 from top to bottom.
The refrigerating chamber 1105 is partitioned from the freezing chamber 1106 by an insulating wall 1108 having an insulating structure. Further, the freezing chamber 1106 and the vegetable chamber 1107 are partitioned by an insulating wall 1109 having an insulating structure.
In the process of manufacturing the refrigerator 1100, the inner case 1103 is disposed inside the outer case 1102, and then the heat insulating material 1104 is foamed and filled between the outer case 1102 and the inner case 1103. Then, the separately prepared insulating wall 1108 and the insulating wall 1109 are embedded inside the inner box 1103. Thus, the refrigerating chamber 1105 is insulated and partitioned from the freezing chamber 1106 by the insulating wall 1108, and the freezing chamber 1106 is insulated and partitioned from the vegetable chamber 1107 by the insulating wall 1109.
However, the above-described conventional techniques still have room for improvement from the viewpoint of improving the cooling efficiency of each storage room.
Specifically, although the refrigerating compartment 1105 and the freezing compartment 1106 are insulated by the insulating wall 1108 prepared separately from the insulating box 1101, since the insulating wall 1108 is a separate member, it is difficult to obtain a high insulating effect by the insulating wall 1108. Similar problems apply to the heat insulating wall 1109 that insulates the freezing chamber 1106 from the vegetable chamber 1107.
In addition, in the process of manufacturing the heat insulation box 1101, the separate preparation of the heat insulation wall 1108 and the heat insulation wall 1109 also leads to an increase in manufacturing cost.

Detailed Description
Hereinafter, the refrigerator 10 according to the embodiment of the present invention will be described in detail based on the drawings. In describing the present embodiment, the same members are denoted by the same reference numerals in principle, and redundant description thereof will be omitted. In the following description, the directions of the upper, lower, front, rear, left, and right are used, but the left and right directions refer to directions when the refrigerator 10 is viewed from the front.
Fig. 1 is a perspective view of a refrigerator 10 of an embodiment of the present invention viewed from the front right side. The refrigerator 10 includes a heat-insulated box 11, and a storage compartment formed inside the heat-insulated box 11. The storage compartment includes a refrigerating compartment 12 and a freezing compartment 13 from top to bottom. The front of the refrigerating compartment 12 is opened, and the upper part of the opening is closed by an insulating door 18 and the lower part is closed by an insulating door 19. The freezing chamber 13 is opened at the front, and an upper section of the opening is closed by an insulation door 20 and a lower section is closed by an insulation door 21. The heat-insulating door 18 is a revolving door, and the heat-insulating doors 19, 20, and 21 are drawer doors. Here, the refrigerating chamber 12 is a first storage chamber, and the freezing chamber 13 is a second storage chamber.
Fig. 2 is a perspective view showing the heat-insulated box 11 with the heat-insulated doors 18, 19, 20, and 21 removed.
The refrigerator compartment 12 includes an upper refrigerator compartment 121 and a lower refrigerator compartment 122. Further, the freezing chamber 13 includes an upper stage freezing chamber 131 and a lower stage freezing chamber 132.
The refrigerating chamber 12 and the freezing chamber 13 are partitioned by an insulating wall 28. The heat insulating wall 28 is a heat insulating member filled with a heat insulating material such as urethane.
Fig. 3 is a side sectional view showing the entire refrigerator 10. The heat-insulating box body 11 includes: an outer case 111 formed by bending a steel plate into a predetermined shape; an inner case 112 formed of a synthetic resin plate and disposed inside the outer case 111; and a heat insulating material 113 filled between the outer case 111 and the inner case 112.
In the present embodiment, inner box 112 includes first inner box 23 and second inner box 24, refrigerating compartment 12 is formed inside first inner box 23, and freezing compartment 13 is formed inside second inner box 24. The first inner case 23 and the second inner case 24 are resin molded bodies formed separately.
The refrigerating chamber 12 and the freezing chamber 13 are partitioned by an insulating wall 28 having an insulating structure. The heat insulating wall 28 is formed by filling a space between the lower surface of the first inner box 23 and the upper surface of the second inner box 24 with a heat insulating material 113. Thus, compared to the heat insulating structure of the related art, it is not necessary to separately prepare a member of the heat insulating wall 28 outside the inner box 112, so that the number of components required for the refrigerator 10 can be reduced. Further, an insulating wall 28 is formed as a part of insulating material 113 between refrigerating room 12 and freezing room 13, and refrigerating room 12 and freezing room 13 can be effectively insulated from each other by insulating wall 28.
The refrigerator 10 has an automatic ice making function, and includes a water supply tank 40, an ice maker 41, and a water guide passage 42. The water supply tank 40 is a water tank disposed at the lowermost stage of the refrigerating chamber 12 and stores water for making ice. The ice maker 41 is an automatic ice maker, is disposed at the uppermost stage of the freezing chamber 13, and automatically makes ice using water supplied from the water supply tank 40. Water is supplied from the water supply tank 40 to the ice maker 41 through the water guide passage 42. The water guide passage 42 is an aluminum pipe, and its upper end side is communicated with the water supply tank 40 and its lower end side is communicated with the ice maker 41.
The communicating portion 30 vertically penetrates the heat insulating wall 28 to communicate the refrigerating chamber 12 and the freezing chamber 13. A specific configuration of the communicating portion 30 will be explained below with reference to fig. 4. The water guide passage 42 penetrates the communication part 30 so that the water supply tank 40 communicates with the water guide passage 42. The water in the water supply tank 40 flows to the ice maker 41 through the water guide passage 42 inserted into the communication part 30.
A cooling chamber 115 is formed inside freezing chamber 13, and freezing chamber 13 and cooling chamber 115 are partitioned by partition 27. An evaporator 116 is disposed as a cooler inside the cooling chamber 115. Further, a machine chamber 14 is formed in a partitioned manner at the rear of the lower end side of the refrigerator 10, and a compressor 22 is disposed in the machine chamber 14. Here, the evaporator 116 and the compressor 22 form the refrigerant compression refrigeration cycle 16 together with a condenser, a dryer, and a capillary tube, which are not shown. By operating the refrigeration cycle 16, the evaporator 116 cools the cold air in the cooling compartment 115 and blows the cold air to each storage compartment, thereby setting the temperature in each storage compartment to a predetermined cooling temperature range.
Inside the cooling chamber 115, the blower 29 is disposed above the evaporator 116. The blower 29 is an axial flow blower or a centrifugal blower, and blows cold air cooled by the evaporator 116 in the cooling chamber 115 to the refrigerating chamber 12 and the freezing chamber 13.
Inside the cooling chamber 115, a defrosting heater 117 is disposed below the evaporator 116. As the refrigerant compression refrigeration cycle operates, frost is generated on the surface of the evaporator 116. In this case, a control device, not shown, stops the compressor 22 to close the cooling chamber 115, and the defrosting heater 117 is energized to generate heat to melt and defrost the frost.
The cold air blown by the blower 29 is blown to the refrigerating chamber 12 and the freezing chamber 13 through an unillustrated air blowing passage. The cold air having cooled refrigerating room 12 and freezing room 13 is returned to cooling room 115 through an unillustrated return air duct. With such a configuration, refrigerating compartment 12 is cooled to a refrigerating temperature range, and freezing compartment 13 is cooled to a freezing temperature range.
The configuration of the communication portion 30 will be described with reference to fig. 4. Fig. 4(a) is a side sectional view showing the communication portion 30, and fig. 4(B) is a sectional view showing the communication portion 30.
Referring to fig. 4(a) and 4(B), the communication portion 30 includes a first fitting portion 31, a second fitting portion 32, and a sealing member 33.
The first fitting portion 31 is attached to the opening on the lower surface of the first inner case 23 shown in fig. 3, and forms an upper portion of the communication portion 30. The first fitting portion 31 has a concave portion 36 that is recessed downward, and a first cylindrical portion 34 is formed at the lower end of the concave portion 36.
The second fitting portion 32 is a member that is mounted at an opening on the upper surface of the second inner case 24 shown in fig. 3, and has a concave portion 37 that is recessed downward. The concave portion 37 is formed at the bottom with a second cylindrical portion 35 protruding upward, which has a cylindrical shape. Further, a bottom portion 38 having a substantially annular shape in plan view is formed inside the second cylindrical portion 35, and a through hole 39 is formed in the center portion of the bottom portion 38.
Referring to fig. 4(a), the inner diameter L11 of the second cylindrical portion 35 is larger than the outer diameter L10 of the first cylindrical portion 34. The inner diameter L11 of the second cylindrical portion 35 is, for example, 6mm or longer than the outer diameter L10 of the first cylindrical portion 34. In other words, the outer surface of the first cylindrical portion 34 is spaced apart from the inner surface of the second cylindrical portion 35. Thereby, the seal member 33 can be disposed between the first cylindrical portion 34 and the second cylindrical portion 35. Here, the sealing member 33 has a flat cylindrical shape, and a through hole is formed in the center thereof, as described below. The width L13 of the through-hole 39 formed in the second cylindrical portion 35 is shorter than the inner diameter L12 of the first cylindrical portion 34 of the communicating portion 30.
The sealing member 33 disposed between the first cylindrical portion 34 of the first fitting portion 31 and the second cylindrical portion 35 of the second fitting portion 32 is formed of, for example, a foamed resin having excellent flexibility, and is compressed between the outer surface of the first cylindrical portion 34 and the inner surface of the second cylindrical portion 35. By forming the sealing member 33, in the step of foaming and filling the heat insulating material 113, the material of the heat insulating material 113 can be prevented from leaking from between the first fitting portion 31 and the second fitting portion 32 to the refrigerating compartment 12 or the freezing compartment 13. Further, the seal member 33 is disposed between the first cylindrical portion 34 and the second cylindrical portion 35 in a state of being compressed in the up-down direction, and therefore, the sealing effect between the first cylindrical portion 34 and the second cylindrical portion 35 can be enhanced.
Next, a method of manufacturing the refrigerator 10 described above will be described with reference to fig. 5 to 7.
Fig. 5(a) is an exploded perspective view showing an assembly process of the first inner casing 23 and the second inner casing 24, and fig. 5(B) is a perspective view showing the seal member 33. First, the first fitting portion 31 is attached to the first opening 25 formed in the lower surface of the first inner case 23, and the second fitting portion 32 is attached to the second opening 26 formed in the upper surface of the second inner case 24.
The first opening 25 is formed by opening a left rear end portion of the lower surface portion 231 of the first inner case 23. The first fitting portion 31 is attached to the lower surface of the first inner case 23 so as to cover the portion where the first opening 25 is formed. The second opening 26 is formed by opening a left rear end portion of the upper surface portion 241 of the second inner case 24. The second fitting portion 32 is attached to the upper surface portion 241 from above.
The sealing member 33 is disposed at the bottom 38 of the second fitting portion 32. As shown in fig. 5(B), the sealing member 33 has a flat cylindrical shape, is formed of a soft material such as a foamed resin, and is formed with a through hole 331 penetrating through the center thereof in the thickness direction.
The water guide passage 42 passes through the first opening 25 of the first inner case 23, the first cylindrical portion 34 of the first fitting portion 31, the through hole 331 of the seal member 33, the second cylindrical portion 35 of the second fitting portion 32, and the second opening 26 of the second inner case 24.
Fig. 6 is a side cross-sectional view showing a state where the first fitting portion 31 of the first inner box 23 is inserted into the second fitting portion 32 of the second inner box 24.
In this step, the first tubular portion 34 of the first fitting portion 31 attached to the lower surface portion 231 of the first inner case 23 is inserted into the second tubular portion 35 of the second fitting portion 32 attached to the upper surface portion 241 of the second inner case 24. At this time, as shown in fig. 4(a), the seal member 33 is compressed between the first cylindrical portion 34 and the second cylindrical portion 35.
Due to machining tolerances, deformation, and the like of the first inner case 23 and the second inner case 24, the first cylindrical portion 34 on the first inner case 23 side and the second cylindrical portion 35 on the second inner case 24 side are displaced in the relative positions in the front-rear and left-right directions. Since the inner diameter L11 of the second cylindrical portion 35 is larger than the outer diameter L10 of the first cylindrical portion 34, the first cylindrical portion 34 can be accurately disposed inside the second cylindrical portion 35 even if the two portions are misaligned. Further, since the seal member 33 is compressed between the second cylindrical portion 35 and the first cylindrical portion 34, it is possible to seal between the first cylindrical portion 34 and the second cylindrical portion 35. This prevents the heat insulator 113 from entering the first inner casing 23 or the second inner casing 24 from between the first cylindrical portion 34 and the second cylindrical portion 35 in the next step.
Through the above-described steps, referring to fig. 5, the communication portion 30 is disposed between the first inner box 23 and the second inner box 24, and the internal space of the first inner box 23 (the refrigerating chamber 12) and the internal space of the second inner box 24 (the freezing chamber 13) are communicated through the communication portion 30.
Referring to fig. 7, an insulating material 113 is then foamed and filled between the inner case 112 and the outer case 111. Fig. 7 is a side sectional view showing the foaming and filling step.
In this step, first, the first inner box 23 and the second inner box 24 that are communicated with each other through the communication portion 30 are disposed inside the heat-insulating box 11. Then, a liquid foaming material, for example, foamed polyurethane, is injected from an opening, not shown, formed in the outer box 111. The injected liquid foaming material fills the space between the outer box 111 and the inner box 112 while foaming. Further, a part of the injected liquid foaming material fills the space between the lower surface 231 of the first inner casing 23 and the upper surface 241 of the second inner casing 24, thereby forming the heat insulating wall 28.
In this step, the pressure of the foamed resin also acts on the communicating portion 30. As shown in fig. 4(a), the gap between the first cylindrical portion 34 of the first fitting portion 31 and the second cylindrical portion 35 of the second fitting portion 32 constituting the communication portion 30 is sealed by the compressed sealing member 33. This prevents the foaming material from entering the refrigerator compartment 12 or the freezer compartment 13 through the gap between the first cylindrical portion 34 and the second cylindrical portion 35.
After the above-described process is completed, referring to fig. 3, water supply tank 40 in refrigerating compartment 12 and ice maker 41 in freezing compartment 13 are connected by water guide passage 42 passing through communication part 30. And assembles an evaporator 116, a defrosting heater 117, and the like to the outer case 111. Further, the heat-insulating doors 18 to 21 shown in fig. 1 are assembled to the heat-insulating box 11. The refrigerator 10 is manufactured through the above-described steps.
The present invention is not limited to the above-described embodiments, and various modifications may be made without departing from the scope of the present invention.
