[0037] Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. In the following description, the same reference numerals will be used to denote the same parts. Their names and functions are also the same. Therefore, detailed descriptions of them will not be repeated.

[0038] [First Implementation Method]

[0039] First, refer to Figures 1 to 3 The overall structure of the refrigerator 100 according to this embodiment will be explained below. Figure 2 The upper part, referred to as the refrigerator 100 and the upper part of each component, will Figure 1 The area below the refrigerator 100 and the area below each component will be... Figure 1 The right side of the refrigerator is referred to as the refrigerator 100 and the right side of each component. Figure 1 The left side of the refrigerator 100 and the left side of each component will be... Figure 1 The direction facing the front of the paper is referred to as the front or frontal direction of the refrigerator 100 and each component. Figure 1 The inside direction of the paper is called the rear or back direction of the refrigerator 100 and each component.

[0040] The refrigerator 100 of this embodiment has a refrigerator compartment 110 in the upper part of the casing 101 and a freezer compartment 120 in the lower part of the casing 101. A refrigerator door 111 is installed on the front of the refrigerator compartment 110, and a freezer door 121 is installed on the front of the freezer compartment 120. Inside the refrigerator compartment 110 of this embodiment, a vegetable drawer 113 is slidably arranged in the lower part along the front-back direction.

[0041] Furthermore, in particular, the refrigerator 100 according to this embodiment can easily modify the door 111, such as... Figure 2 As shown, the door 111 opens and closes with its right end as the axis. Figure 3 As shown, it opens and closes with the left end as the axis. The following describes the mounting configuration of such a door 111 relative to the housing 101.

[0042] <Installation configuration at the upper end of the door>

[0043] like Figure 4 As shown, in this embodiment, a left-upper hinge 130L is provided at the upper left end of the front of the refrigerator compartment 110. More specifically, a metal hinge retaining plate 131L is bolted to the left end of the front end of the top surface 101T of the metal casing 101 constituting the refrigerator 100, and a hinge pin is pivotally supported in the hinge hole formed in the hinge retaining plate 131L.

[0044] Similarly, a right-side hinge 130R is provided at the upper right end of the front of the refrigerator compartment 110. More specifically, a metal hinge retainer plate 131R is bolted to the right end of the front end of the top surface 101T of the metal shell 101 constituting the refrigerator 100, and a hinge pin is pivotally supported in the hinge hole formed in the hinge retainer plate 131R.

[0045] Thus, in this embodiment, since the left hinge hole is formed on the metal hinge retaining plate 131L and the right hinge hole is formed on the hinge retaining plate 131L, and the two plates are positioned on the metal top surface 101T, the assembly accuracy of the spacing between the two hinge holes is improved.

[0046] The following will refer to Figures 5 to 7 The structure of the upper right hinge 130R is explained. In this embodiment, the hinge retaining plate 131R, the resin sleeve component 133R, and the head of the hinge pin 135 are arranged in the following order from bottom to top.

[0047] In this embodiment, the hinge retaining plate 131R is made of a metal plate. The rear half 131B of the hinge retaining plate 131R is fixed to the right end of the front end of the top surface 101T by three bolts 132, 132, 132. The front half 131F of the hinge retaining plate 131R is formed higher than the rear half 131B by a stepped portion 131M of the central plate. A left-facing recess 131X is formed on the right side of the rear portion of the front half 131F. In other words, the hinge retaining plate 131R extends forward from the left side of the center in the front-rear direction when viewed from above, and then bends to the right. A hinge hole 131S is formed at the right end of the front portion of the front half 131F, and a pin hole 131T is formed to its left.

[0048] A resin sleeve component 133R is mounted on the upper surface of the front end of the upper right hinge 130R. The resin sleeve component 133R is fixed to the front end and right end of the hinge retaining plate 131R by a screw 134 from below the hinge retaining plate 131R. A hinge hole 133S is also formed on the resin sleeve component 133R. The hinge hole 133S is formed in a cylindrical shape facing downward. Thus, in this embodiment, the inner peripheral surface of the hinge hole 131S of the hinge retaining plate 131R is covered by the cylindrical portion 133H. That is, the bottom surface of the head of the hinge pin 135, the side surface of the body of the hinge pin 135, do not directly rub against the upper surface of the hinge retaining plate 131R and the inner peripheral surface of the hinge hole 131S, allowing the hinge pin 135 to rotate smoothly within the hinge hole 131S. Furthermore, in other words, the resin sleeve component 133R is configured such that it is sandwiched between a metal hinge pin 135 and a metal hinge retaining plate 131R.

[0049] In this embodiment, the resin sleeve component 133R has a raised portion 133X on the left square of the hinge hole 133S, and an anti-fall-off portion 133Y is formed on the right rear side from the upper part of the raised portion 133X.

[0050] In this embodiment, the head and lower part of the body of the hinge pin 135 are D-shaped cuts. With the door 111 closed, and the cut portion 135D aligned with the anti-detachment portion 133Y, the hinge pin 135 is inserted into the hinge hole 131S and then into the hinge hole 111TR at the right end of the top surface of the door 111. The hinge pin 135 rotates together with the door 111 as the door 111 opens and closes.

[0051] Because of this configuration, even if the user pulls the hinge pin 135 upward from the hinge hole 131S while the door 111 is open, as... Figure 8As shown, the uncut portion of the hinge pin 135 also collidees with the bottom surface of the anti-detachment part 133Y, thus preventing the hinge pin 135 from being pulled out from the resin sleeve part 133R, the hinge retaining plate 131R, and the door 111. That is, in this embodiment, with the door 111 open, the hinge pin 135 cannot be removed from the housing 101 or the hinge retaining plate 131R.

[0052] Furthermore, when the door 111 is closed, in the same state as when it is inserted into the hinge pin 135, that is, when the cut portion 135D of the hinge pin 135 is facing the anti-detachment portion 133Y, the hinge pin 135 and the anti-detachment portion 133Y can be pulled out without contact.

[0053] Furthermore, the upper left hinge 130L is roughly symmetrical to the upper right hinge 130R, so it will not be described again here.

[0054] <Installation structure at the lower end of the door>

[0055] like Figure 9 As shown, in this embodiment, a lower left hinge 140L is provided at the lower left end of the front of the refrigerator compartment 110. More specifically, a metal hinge retaining plate 141L is fixed with bolts, and a hinge pin 145 is pivotally supported in a hinge hole formed in the hinge retaining plate 141L. The hinge retaining plate 141L is located at the left end of the front end of the partition frame 103 that constitutes the upper and lower approximately central portion of the housing 101 of the refrigerator 100.

[0056] Similarly, a lower right hinge 140R is provided at the lower right end of the front of the refrigerator compartment 110. More specifically, a metal hinge retainer plate 141R is fixed with bolts, and a hinge pin 145 is pivotally supported in a hinge hole formed in the hinge retainer plate 141R. The hinge retainer plate 141R is located at the right end of the front end of the partition frame 103 that constitutes the upper and lower approximately central part of the shell 101 of the refrigerator 100.

[0057] More specifically, such as Figures 9 to 11 As shown, bolt holes 141H, 141H... are formed on the vertical surface of the rear part of the hinge retaining plate 141R on the right side for fixing to the left end of the front end of the partition frame 103 between the refrigerator compartment 110 and the freezer compartment 120. Moreover, hinge holes 141S for inserting hinge pins 145 are formed in the horizontal surface of the front part of the right side of the hinge retaining plate 141R.

[0058] A resin cover 143R is mounted on the upper surface of the hinge retaining plate 141R. More specifically, the resin cover 143R covers the upper surface and the periphery of the sides of the hinge retaining plate 141R, as well as the inner circumferential surface of the hinge hole 141S. That is, the resin cover 143R has a downwardly rectangular, cylindrical hinge hole 143S at the portion corresponding to the hinge hole 141S of the hinge retaining plate 141R.

[0059] Thus, the metal hinge pin 145 is pivotally supported in the hinge hole 141S via the resin cover 143R in a manner that does not directly rub against the hinge hole 141S of the metal hinge retaining plate 141L.

[0060] The front portion of the hinge hole 141S in the hinge retaining plate 141R is configured as an arc shape. In this embodiment, the portion of the resin cover 143R that covers the front portion of the hinge hole 141S is formed as a generally planar abutment portion 143X. Therefore, even when the door 111 is open with its left end as the axis, and even when the door 111 is forcibly closed or when the refrigerator 100 is transported with the door 111 raised, damage is less likely to occur because the stop 112R on the back of the door 111 collides with the planar abutment portion 143X of the resin cover 143R.

[0061] More specifically, when the front end of the hinge hole 141S in the hinge retaining plate 141R or resin cover 143R is arc-shaped, the stop 112R on the back of the door 111 makes point or line contact with this front end portion. Therefore, the front of the resin cover 143R or the back of the stop 112R of the door 111 is likely to be scratched or dented. In this embodiment, since the front end of the resin cover 143R is flat, the back of the door 111 makes surface contact with this front end portion. Therefore, the front of the resin cover 143R or the back of the door 111 is unlikely to be scratched or dented.

[0062] Furthermore, the lower left hinge 140L is roughly symmetrical to the lower right hinge 140R, so it will not be described again here.

[0063] [Second Implementation]

[0064] Other configurations will be described, including one in which the resin sleeve component is held between the hinge pin 135 and the metal hinge retaining plates 131L and 131R. In this embodiment, a configuration in which the hinge pin 135 can be easily pulled out from the resin sleeve component or the metal hinge retaining plates 131L and 131R will be described.

[0065] The hinge retaining plates 131L and 131R, and the hinge pin 135 involved in this embodiment are constructed in the same way as in the embodiment described above. That is, in this embodiment, since the left hinge hole is formed on the metal hinge retaining plate 131L, the right hinge hole is formed on the hinge retaining plate 131L, and the two plates are positioned on the metal top surface 101T, the assembly accuracy of the spacing between the two hinge holes is improved.

[0066] The following will refer to Figures 12 to 14 The structure of the upper right hinge 230R is explained. In this embodiment, the components are arranged in the following order from bottom to top: hinge retaining plate 131R, resin sleeve component 233R, rotating component 236R, and the head of hinge pin 135.

[0067] A resin sleeve component 233R is disposed on the upper surface of the front end of the hinge retaining plate 131R on the right side. A hinge hole 233S is formed in the resin sleeve component 233R. The hinge hole 233S is formed in a cylindrical shape facing downward. Thus, in this embodiment, the inner peripheral surface of the hinge hole 131S of the hinge retaining plate 131R is covered by the cylindrical portion 233H. That is, the hinge pin 135 is configured such that the bottom surface of the head of the hinge pin 135, the side surface of the body of the hinge pin 135, do not directly rub against the upper surface of the hinge retaining plate 131R and the inner peripheral surface of the hinge hole 131S, allowing the hinge pin 135 to rotate smoothly within the hinge hole 131S. Furthermore, in other words, the resin sleeve component 233R is configured such that it is sandwiched between the metal hinge pin 135 and the metal hinge retaining plate 131R.

[0068] In this embodiment, a sliding portion 233X is formed at the left end of the resin sleeve component 233R, facing upward. The sliding portion 233X is fixed to the front end of the hinge retaining plate 131 by a screw 134 from below the hinge retaining plate 131R, thereby fixing the resin sleeve component 233R to the front end of the hinge retaining plate 131R.

[0069] A sliding part 233X is embedded in the rotating member 236R from above. The rotating member 236R is mounted so that it can rotate about the sliding part 233X as an axis and slide in the vertical direction.

[0070] An anti-detachment portion 236Y is formed in the rotating component 236R. The anti-detachment portion 236Y is formed at a position higher than the head of the hinge pin 135 and extends to the right from the sliding portion 233X.

[0071] A pointed portion 236X is formed in the rotating component 236R, which is used for rear insertion between the head of the hinge pin 135 and the resin sleeve component 233R. An operating portion 236W for gripping and pressing the rotating component 236R with a finger is formed further to the right of the pointed portion 236X.

[0072] In this embodiment, when door 111 is closed, such as Figure 15 as well as Figure 16 As shown, the operator can push the operating part 236W forward toward the cut portion 135D on the back of the hinge pin 135. This allows the pointed part 236X to be inserted between the lower surface of the head of the hinge pin 135 and the upper surface of the resin sleeve component 233R, pushing the head of the hinge pin 135 upward. Simultaneously, by rotating the rotating component 236R, the anti-falling part 236Y moves forward, ensuring there are no obstructions above the hinge pin 135.

[0073] Furthermore, in this embodiment, a slit 236V is formed in the vertical direction on the right side of the rotating member 236R, between the anti-detachment portion 236Y and the sharp portion 236X, and a protrusion 233V is formed on the right side of the upper end of the sliding portion 233X of the resin sleeve member 233R. Figure 16 As shown, when the pointed part 236X is inserted between the lower surface of the head of the hinge pin 135 and the upper surface of the resin sleeve part 233R, the anti-detachment part 236Y moves forward, there is no obstruction above the hinge pin 135, and the protrusion 233V is located above the slit 236V.

[0074] In this state, such as Figure 17 As shown, the rotating component 236R and the hinge pin 135 can be lifted, and the hinge pin 135 can be pulled out from the hinge hole 111TR and the hinge retaining plate 131R of the door 111.

[0075] Furthermore, in this embodiment, when the door 111 is open, even if the operating part 236W is pushed forward, the front surface 236Z of the operating part 236W will collide with the uncut portion of the hinge pin 135, preventing the rotating member 236R from rotating. Therefore, the anti-drop portion 236Y remains above the hinge pin 135, making it impossible to pull the hinge pin 135 out of the resin sleeve member 233R, the hinge retaining plate 131R, and the door 111. Additionally, since the protrusion 233V does not reach the upper part of the slit 236V, the rotating member 236R cannot be pulled out from the resin sleeve member 233R. In other words, when the door 111 is open, the door 111 cannot be removed from the housing 101.

[0076] Furthermore, the upper left hinge is roughly symmetrical to the upper right hinge 230R, so it will not be described again here.

[0077] [Third Implementation Method]

[0078] In this embodiment, other configurations that allow the hinge pin 135 to be easily pulled out of the resin sleeve component or the metal hinge retaining plates 131L and 131R will be described.

[0079] The hinge retaining plates 131L and 131, and the hinge pin 135 involved in this embodiment are constructed in the same way as in the embodiment described above. That is, in this embodiment, since the left hinge hole is formed on the metal hinge retaining plate 131L, the right hinge hole is formed on the hinge retaining plate 131L, and the two plates are positioned on the metal top surface 101T, the assembly accuracy of the spacing between the two hinge holes is improved.

[0080] The following will refer to Figures 18 to 20 The structure of the upper right hinge 130R is explained. In this embodiment, the components are arranged in the following order from bottom to top: hinge retaining plate 131R, resin sleeve component 333R, gap component 336, and the head of hinge pin 135.

[0081] A resin sleeve member 333R is disposed on the upper surface of the front end of the hinge retaining plate 131R. A hinge hole 333S is formed in the resin sleeve member 333R. The hinge hole 333S is formed in a cylindrical shape facing downward. Thus, in this embodiment, the inner peripheral surface of the hinge hole 131S of the hinge retaining plate 131R is covered by the cylindrical portion 333H. That is, the bottom surface of the head of the hinge pin 135 and the side surface of the body of the hinge pin 135 do not directly rub against the upper surface of the hinge retaining plate 131R and the inner peripheral surface of the hinge hole 131S, allowing the hinge pin 135 to rotate smoothly within the hinge hole 131S. Furthermore, in other words, the resin sleeve member 333R is configured such that it is sandwiched between the metal hinge pin 135 and the metal hinge retaining plate 131R.

[0082] Furthermore, in this embodiment, a gap member 336 is held between the upper surface of the resin sleeve member 333R and the bottom surface of the head of the hinge pin 135. More specifically, the gap member 336 is composed of a bottom surface 336A, a vertical portion 336B formed vertically upward from the left side of the bottom surface 336, and an upper surface 336C formed horizontally from the upper end of the vertical portion 336B towards the hinge hole 131S. The upper surface 336C is located at a position higher than the hinge pin 135. Furthermore, with the right side of the bottom surface 336A sandwiched between the upper surface of the resin sleeve member 333R and the bottom surface of the head of the hinge pin 135, a screw 334 is screwed into the threaded hole 336T of the vertical portion 336B from above, thereby threading the gap member 336 to the resin sleeve member 333R from above.

[0083] Therefore, in this embodiment, the operator removes the screw 334 and lifts the hinge pin 135 upward together with the clearance component 336, so that the hinge pin 135 can be pulled out from the hinge hole 111TR and the hinge retaining plate 131R of the door 111.

[0084] More specifically, in this embodiment, the portion below the longitudinal portion 336B of the resin sleeve component 333R is recessed. (See also...) Figure 21 and Figure 22 After removing screw 334, the operator presses the left side of the clearance component 336 downward and pushes the right side of the clearance component 336 upward using the lever principle. This lifts the bottom surface of the head of the hinge pin 135 upward and pulls the hinge pin 135 out of the hinge hole 111TR and hinge retaining plate 131R of the door 111.

[0085] Alternatively, the hinge pin 135 may have a cut portion 135D, such that the upper surface 336C of the gap member 336 relative to 135D is in the same positional relationship as the anti-detachment portion 133Y in the first embodiment. Thus, with the door 111 open, the hinge pin 135 can be removed from the housing 101 or the hinge retaining plate 131R.

[0086] Furthermore, the upper left hinge is roughly symmetrical to the upper right hinge 330R, so it will not be described again here.

[0087] [Fourth Implementation Method]

[0088] Based on the above embodiments, the hinge pin 135, which is cut in a D-shape, can also be used to add a stabilizing effect when the door 111 is closed. For example, as Figure 23 and Figure 24 As shown, the resin sleeve component 433R on the right side has a pressing part 433Z that abuts against the cut portion 135D of the hinge pin 135 when the door 111 is closed. More specifically, the front end of the pressing part 433Z preferably presses forward toward the right side of the face of the cut portion 135D of the hinge pin 135 when the door 111 is closed.

[0089] Therefore, as Figures 23 to 25 As shown, this design prevents the door 111 from opening unnecessarily when vibrations are applied to it. Furthermore, by sensing the resistance generated when the user moves the pressing part 433Z from the cut portion 135D to the uncut portion while opening the door 111, the likelihood of forgetting to close the door 111 can be reduced.

[0090] Conversely, a pressing portion 433Z is also formed on the resin sleeve component 433L on the left side, which abuts against the D-shaped cut portion of the hinge pin 135 when the door 111 is closed. More specifically, preferably, the front end of the pressing portion 433Z presses forward toward the left side of the cut surface of the hinge pin 135 when the door 111 is closed. This reduces the possibility of the door 111 being opened carelessly or the user forgetting to close the door 111.

[0091] Furthermore, the upper left hinge is roughly symmetrical to the upper right hinge 430R, so it will not be described again here.

[0092] [Summarize]
