Description

Refrigerator with a door

Technical Field

Embodiments of the present invention relate to a refrigerator.

Background

The refrigerator has a door supported by lower and upper support parts provided at upper and lower parts of the door, and a front opening of a storage chamber formed in a refrigerator main body is closed by the door.

In a refrigerator having a swing door, when an installation surface of the refrigerator is inclined or a heavy object is stored in a storage space of the door, a refrigerator body is deformed, and thus the door is vertically displaced from a predetermined position. In particular, in a left-right split door in which the door is divided into left and right, the vertical displacement of the door may cause a step at the butt joint portion on the opposite side of the pivot supports of the left and right doors, which may significantly impair the appearance quality.

When the refrigerator is set, the inclination of the refrigerator main body is corrected by adjusting the height of the front leg, thereby also suppressing the positional deviation of the door. However, the vertical position of the door cannot be directly adjusted by adjusting the height of the front leg, which makes the adjustment work complicated, or the adjustment amount is small, which makes the adjustment insufficient.

Patent document 1 discloses the following: the height of the hinge shaft is adjusted by rotating the hinge shaft engaged with a screw hole formed at the refrigerator main body side, so that the position of the door in the vertical direction can be adjusted. In the refrigerator of patent document 1, since it is necessary to provide: the rotation stopper is used for inhibiting the rotation of the hinge shaft, so the vertical position of the door can be adjusted when the refrigerator is assembled, but the height of the hinge shaft can not be adjusted when the door is supported, and the vertical position of the door can not be adjusted after the user sets the refrigerator.

An adjusting portion 70 is provided inside the second tube portion 42b and between the stepped portion 42c of the tube portion 42 constituting a part of the lower surface of the right door 11 and the upper surface of the shaft support portion 52.

The adjusting portion 70 is capable of adjusting, in a state where the upper supporting portion 22 and the lower supporting portion 23 support the right door 11, that is, in a state where the right door 11 is attached to the refrigerator main body 2, by changing a position in the vertical direction in contact with the step portion 42c of the cylinder portion 42: the right door 11 is positioned in the vertical direction with respect to the refrigerator main body 2 when the right door 11 closes the front opening of the refrigerating chamber 3.

Specifically, the adjustment unit 70 includes: an upper member 71 and a lower member 72 provided around the lower pin 53, wherein the upper member 71 is provided on the upper side of the lower member 72 in an overlapping manner.

The upper member 71 includes: an insertion hole 73 through which the lower pin 53 is inserted, and a protrusion 81 provided around the lower pin 53. In the present embodiment, as shown in fig. 6, the upper member 71 is fixed to: the door stopper 40 is provided integrally with the lower surface of the stepped portion 42c of the cylindrical portion 42 provided in the door stopper 40.

The projection 81 projects downward from the lower surface of the stepped portion 42c of the cylindrical portion 42, and the lower surface thereof comes into surface contact with the stepped portion 75 of the lower member 72. In the present embodiment, n (n is an integer of 2 or more, and 2 in the present embodiment) projections 81 are provided at predetermined intervals so as to be symmetrical around the lower pin 53. The two projections 81 are all set to the same height (projection amount), and the lower surface of each projection 81 is: and inclined surfaces which come into surface contact with the inclined surfaces 74a1, 74b1, 74c1, 74d1 of the stepped

portions

As shown in fig. 6, a cutout portion 44 is provided on a side surface of the base portion 41 of the door stopper 40 at a position corresponding to the projection 81.

As shown in fig. 7, the lower member 72 is: a lower member 72 for molding a synthetic resin such as polyacetal or polypropylene into a member having a predetermined shape which can be accommodated in the 2 nd cylindrical portion 42b, the lower member comprising: an insertion hole 79 through which the lower pin 53 is inserted; a step portion 75 provided around the lower pin 53; and a clamp engaging portion 80 provided at a lower portion of the peripheral surface of the lower member 72.

The insertion through hole 79 is provided: slightly larger than the outer diameter of the lower pin 53. When the lower pin 53 is inserted into the insertion hole 79, a predetermined gap is formed between the lower pin 53 and the insertion hole 79, and the lower member 72 is disposed on the upper surface of the shaft support portion 52 of the lower hinge portion 50 so as to be rotatable around the lower pin 53.

The step portions 75 are provided so as to correspond to the n projections 81 provided on the upper member 71, respectively. That is, n (2 in the present embodiment) step portions 75 are provided at predetermined intervals around the lower pin 53. The n steps 75 are all formed in the same shape and are provided symmetrically around the lower pin 53.

The step portion 75 is composed of a plurality of (4 in the present embodiment) first step portions 74a, second step portions 74b, third step portions 74c, and fourth step portions 74d that protrude upward. The first step portion 74a has the highest projection height, and the projection heights are sequentially decreased in the order of the first step portion 74a, the second step portion 74b, the third step portion 74c, and the fourth step portion 74 d.

The upper surfaces of the stepped

portions

74a, 74b, 74c, and 74d constituting the stepped portion 75 contact the projection 81 of the upper member 71. The upper surfaces of the

step portions

74a, 74b, 74c, and 74d are: the inclined surfaces 74a1, 74b1, 74c1, 74d1 are inclined so that the projection height gradually decreases toward the stepped

portions

74b, 74c, 74d having a low projection height. On the side of the inclined surfaces 74a1, 74b1, 74c1, 74d1 where the projection height is low, there are provided: and projecting surfaces 74a2, 74b2, 74c2, 74d2 projecting upward.

In the present embodiment, the protrusion surface 74a2 protruding upward from the inclined surface 74a1 constituting the upper surface of the first stepped portion 74a having the largest protrusion height is connected to the inclined surface 74b1 of the adjacent second stepped portion 74 b. The protruding surface 74b2 protruding upward from the inclined surface 74b1 of the second stepped portion 74b is connected to the inclined surface 74c1 of the adjacent third stepped portion 74 c. The protruding surface 74c2 protruding upward from the inclined surface 74c1 of the third stepped portion 74c is connected to the inclined surface 74d1 of the adjacent fourth stepped portion 74 d. The projecting surface 74d2 projecting upward from the inclined surface 74d1 of the fourth stepped portion 74d is connected to the inclined surface 74a1 of the first stepped portion 74a of the stepped portion 75 provided adjacent to and surrounding the lower pin 53.

The jig engaging portion 80 is provided at a lower portion of the peripheral surface of the lower member 72, has a polygonal cross section (hexagonal shape in the present embodiment), and engages with an adjustment jig 90 described later.

The jig engaging portion 80 is provided with: and a flange portion 83 projecting radially outward. On the upper surface of the flange portion 83, marks 82 are provided corresponding to the plurality of stepped

portions

74a, 74b, 74c, and 74d constituting the stepped portion 75, respectively. Specifically, "3" is displayed radially outward of the first stepped portion 74a, "2" is displayed radially outward of the second stepped portion 74b, "1" is displayed radially outward of the third stepped portion 74c, and "0" is displayed radially outward of the fourth stepped portion 74 d.

In such a configuration, in a normal state in which right door 11 is supported by upper support portion 22 and lower support portion 23, the weight of right door 11 is supported by lower hinge portion 50. Therefore, as shown in fig. 4, the upper member 71 is pressed against the lower member 72 by the self weight of the right door 11. When the upper member 71 is pressed against the lower member 72 by the self weight of the right door 11, the projection 81 provided on the upper member 71 is pressed against: any one of the inclined surfaces 74a1, 74b1, 74c1, 74d1 provided in the step portion 75 of the lower member 72. The protrusion 81 is guided to the protruding surfaces 74a2, 74b2, 74c2, and 74d2 by the inclination of the inclined surfaces 74a1, 74b1, 74c1, and 74d1, and is fitted between the inclined surfaces 74a1, 74b1, 74c1, and 74d1 and the protruding surfaces 74a2, 74b2, 74c2, and 74d2, whereby the upper member 71 and the lower member 72 are engaged with each other.

Thus, when the upper member 71 is engaged with the lower member 72, it is prohibited that: the lower member 72 is pivotally rotatable about the lower pin 53 with respect to the upper member 71. That is, in the present embodiment, the protrusion 81, the inclined surfaces 74a1, 74b1, 74c1, 74d1, and the protruding surfaces 74a2, 74b2, 74c2, 74d2 function as inhibiting portions, and by the inhibiting portions, it is possible to inhibit: one of the lower member 72 and the upper member 71 is pivoted about the lower pin 53 with respect to the other.

Therefore, in the refrigerator 1 of the present embodiment, when the upper member 71 rotates around the lower pin 53 when the right door 11 is opened and closed, the lower member 72 also rotates around the lower pin 53 together with the upper member 71. In a state where the vertical position of the right door 11 does not change and the height is maintained at a constant level, the right door 11 pivots about the lower pin 53.

When the upper member 71 is engaged with the lower member 72, one of the marks 82 provided on the flange portion 83 of the lower member 72 is vertically aligned with the notch portion 44 provided on the base portion 41 of the door stopper 40. As shown in fig. 5, in a state where the lower pin 53 is inserted into the tube portion 42 of the door stopper 40 and the right door 11 is supported by the lower support portion 23 and remains unchanged, the user, once lifting the right door 11 upward, can visually see from obliquely above: the cutout portion 44 of the door stopper 40, and the mark 82 of the lower member 72. Thus, in a state where the right door 11 is supported by the lower support portion 23, it can be confirmed that: the projection 81 of the upper member 71 is vertically opposed to one of the plurality of steps constituting the step 75 of the lower member 72.

Next, a method of adjusting the vertical position of the right door 11 with respect to the refrigerator main body 2 will be described.

First, right door 11 is lifted upward from a state where lower hinge portion 50 supports the weight of right door 11. When the right door 11 is lifted upward, the door stopper 40 fixed to the right door 11 moves upward, and therefore, the upper member 71 integrally provided on the door stopper 40 also moves upward, and the engagement between the upper member 71 and the lower member 72 is released (see fig. 5).

Then, in a state where the engagement between the upper member 71 and the lower member 72 is released, the adjustment jig 90 is engaged with the jig engaging portion 80 of the lower member 72, and the lower member 72 is rotated by a predetermined angle about the lower pin 53 by using the adjustment jig 90 until the mark 82 of the lower member 72 coincides with the notch 44 of the door stopper 40.

When the lower member 72 is rotated by a predetermined angle about the lower pin 53 in this way, the position of the step portion 75 provided in the lower member 72 is changed around the side pin 53, and the projection 81 of the upper member 71 is opposed to the

step portions

74a, 74b, 74c, and 74d of different projection heights provided in the step portion 75 of the lower member 72. At this time, the n projections 81 provided on the upper member 71 face the

step portions

74a, 74b, 74c, and 74d of the n step portions 75 provided on the lower member 72, which have the same height.

After the lower member 72 is rotated by a predetermined angle about the lower pin 53, the right door 11 is lifted up, and the weight of the right door 11 is supported by the lower hinge portion 50. Then, the projection 81 of the upper member 71 comes into contact with the lower member 72 at the stepped

portions

74a, 74b, 74c, and 74d having different projection heights from those before the lower member 72 is rotated. That is, in the present embodiment, if the lower member 72 is rotated about the lower pin 53, the contact position between the projection 81 of the upper member 71 and the

step portions

74a, 74b, 74c, and 74d of the lower member 72 changes in the vertical direction. Accordingly, the contact position between the adjusting portion 70 and the lower surface of the right door 11 is changed in the vertical direction, and the vertical position of the right door 11 with respect to the refrigerator main body 2 can be adjusted.

As described above, in the refrigerator 1 of the present embodiment, the position of the right door 11 in the vertical direction with respect to the refrigerator main body 2 can be adjusted in a state where the right door 11 is supported between the upper support portion 22 and the lower support portion 23. Therefore, even after the user sets the refrigerator 1, the positional deviation in the vertical direction of the left door 10 and the right door 11 can be easily corrected, and the appearance quality can be favorably maintained.

In the present embodiment, the stepped

portions

74a, 74b, 74c, and 74d provided in the lower member 72 constitute: since the step portions 75 have the projecting heights that vary sequentially around the lower pin 53, the vertical position of the right door 11 with respect to the refrigerator main body 2 can be changed in stages.

In the present embodiment, the upper member 71 and the lower member 72 are provided with: the n steps 75 and the n projections 81 are provided, and the n projections 81 are opposed to the

steps

74a, 74b, 74c, and 74d of the same projection height provided in the n steps 75 of the lower member 72. Therefore, the upper member 71 and the lower member 72 can be brought into contact with each other at a plurality of positions around the lower pin 53, and the right door 11 can be stably supported while suppressing rattling.

In the present embodiment, the

step portions

74a, 74b, 74c, and 74d constituting the step portion 75 include: inclined surfaces 74a1, 74b1, 74c1, 74d1 inclined so that the projection height gradually decreases toward stepped

portions

74b, 74c, 74d having a lower projection height, and projection surfaces 74a2, 74b2, 74c2, 74d2 projecting from one of the inclined surfaces 74a1, 74b1, 74c1, 74d1 having a lower projection height. Therefore, even if the positions of the projection 81 of the upper member 71 and the stepped

portions

74a, 74b, 74c, and 74d of the lower member 72 are not vertically accurately aligned when the lower member 72 is rotated about the lower pin 53 while the right door 11 is lifted, when the weight of the right door 11 is supported by the lower hinge portion 50, the projection 81 is guided to the projecting surfaces 74a2, 74b2, 74c2, and 74d2 by the inclination of the inclined surfaces 74a1, 74b1, 74c1, and 74d1, and is fitted between the inclined surfaces 74a1, 74b1, 74c1, and 74d1 and the projecting surfaces 74a2, 74b2, 74c2, and 74d2, whereby the upper member 71 and the lower member 72 can be reliably engaged with each other.

Further, when the upper member 71 is engaged with the lower member 72, it is prohibited that: since the lower member 72 is pivoted about the lower pin 53 with respect to the upper member 71, the vertical position of the right door 11 does not change unexpectedly.

(second embodiment)

The second embodiment will be described mainly with reference to fig. 8 to 13, focusing on a part different from the first embodiment. The same components as those in the first embodiment are denoted by the same reference numerals, and detailed description thereof is omitted.

In the refrigerator 1 of the present embodiment, there are provided: an adjusting portion 170 for adjusting the vertical position of the right door 11 with respect to the refrigerator main body 2. The adjustment unit 170 includes: a lower member 172 provided with a projection 181, and an upper member 171 provided with a step 175, wherein the upper member 171 is overlapped on the lower member 172.

As shown in fig. 8 and 9, the upper member 171 includes: an insertion hole 173 through which the lower pin 53 is inserted, and a step 175 provided around the lower pin 53. In the present embodiment, as shown in fig. 9, 11, and 12, the upper member 171 is fixed to the lower surface of the stepped portion 42c of the cylindrical portion 42 and is provided integrally with the door stopper 40.

The step portion 175 is constituted by a plurality of step portions 174, and the projecting heights of the plurality of step portions 174 projecting downward from the lower surface of the step portion 42c of the cylindrical portion 42 sequentially change around the lower pin 153. The lower surface of the step portion 174 constituting the step portion 175 is: a horizontal surface (a surface perpendicular to the axial direction of the lower pin 53) vertically opposed to the lower member 172.

In the present embodiment, as shown in fig. 9, n (n is an integer of 2 or more, and 2 in the present embodiment) stepped portions 175 are provided at predetermined intervals so as to be symmetrical around the lower pin 53. At least one of the n stepped portions 175 provided in the upper member 171 is provided with: a rotation stop protrusion 176 protruding downward. In the present embodiment, the rotation stop protrusion 176 is described as a protrusion extending in the radial direction of the lower pin 53, but may be in the form of a column, a hemisphere, or the like.

As shown in fig. 8 and 9, a plurality of cutout portions 44 are provided around the second tube portion 42b in the base portion 41 of the door stopper 40, and the plurality of cutout portions 44 are provided so as to correspond to the plurality of step portions 174 constituting the step portion 175.

As shown in fig. 10, the lower member 172 is a member formed by molding a synthetic resin such as polyacetal or polypropylene into a predetermined shape that can be accommodated in the second tube portion 42 b. The lower member 172 includes: an insertion hole 179 through which the lower pin 53 is inserted; a protrusion 181 provided around the lower pin 53; and a clamp engaging portion 180 provided at a lower portion of the peripheral surface of the lower member 172.

The insertion holes 179 are arranged such that: slightly larger than the outer diameter of the lower pin 53. When the lower pin 53 is inserted into the insertion hole 179, a predetermined gap is formed between the lower pin 53 and the insertion hole 179, and the lower member 172 is disposed on the upper surface of the shaft support portion 52 of the lower hinge portion 50 so as to be rotatable around the lower pin 53.

The protrusions 181 are provided such that: and projects upward toward the stepped portion 174 of the upper member 171. In the present embodiment, one projection 181 is provided for each of the n steps 175 provided on the upper member 171, that is, the n projections 181 are provided at predetermined intervals around the lower pin 53. The n projections 181 are all set to the same height (projection amount), and the upper surface of each projection 181 is: a horizontal surface vertically opposed to the upper member 171.

The n projections 181 are provided with detent recesses 178, respectively, and the detent projections 176 provided on the step portion 174 of the upper member 171 are fitted into the detent recesses 178. As shown in fig. 11, when the upper member 171 is pressed against the lower member 172 by the weight of the right door 11, the detent concave portion 178 engages with the detent convex portion 176 provided on the step portion 174 of the upper member 171. Thus, the rotation stop protrusion 176 and the rotation stop recess 178 function as a prohibition portion that prohibits: one of the lower member 172 and the upper member 171 is pivoted about the lower pin 53 with respect to the other, and when the upper member 171 is pivoted about the lower pin 53 during opening and closing of the right door 11, the lower member 172 is also pivoted about the lower pin 53 together with the upper member 171.

Marks 182 are provided on the side and bottom surfaces of the lower member 172 at positions corresponding to the projections 181.

When the detent protrusion 176 of the upper member 171 engages with the detent recess 178 of the lower member 172, as shown in fig. 13(a) to (d), the mark 182 on the side surface of the lower member 172 vertically coincides with one of the plurality of notch portions 44 provided in the base portion 41 of the door stopper 40. The user can visually recognize the notch 44 of the door stopper 40 and the mark 182 of the lower member 172 by looking up the lower support portion 23 from below to obliquely above, or can visually recognize the notch 44 and the mark 182 from the horizontal direction in a state where the lower support portion 23 supports the right door 11 and holds it and then lifts the right door 11 upward as shown in fig. 12. Therefore, in a state where the lower support portion 23 supports and keeps the right door 11, it can be confirmed that: the protrusion 181 of the lower member 172 is in contact with one of the step portions 174 of the plurality of step portions 174 constituting the step portion 175 of the upper member 171.

The jig engaging portion 180 is provided at a lower portion of the peripheral surface of the lower member 172, has a polygonal cross section (hexagonal shape in the present embodiment), and engages with the adjustment jig 90.

In such a configuration, in order to adjust the vertical position of the right door 11 with respect to the refrigerator main body 2, first, the right door 11 is lifted upward. In a normal state in which the upper support portion 22 and the lower support portion 23 support the right door 11, since the weight of the right door 11 is supported by the lower hinge portion 50, the upper member 171 is pressed against the lower member 172 by the weight of the right door 11 as shown in fig. 11.

When the right door 11 is lifted upward from this state, the door stopper 40 fixed to the right door 11 moves upward, and therefore, the upper member 171 integrally provided in the door stopper 40 also moves upward, and the engagement between the upper member 171 and the lower member 172 is released (see fig. 12).

Then, in a state where the engagement between the upper member 171 and the lower member 172 is released, the adjustment jig 190 is engaged with the jig engaging portion 180 of the lower member 172, and the lower member 172 is rotated by a predetermined angle about the lower pin 53 by using the adjustment jig 190 until the mark 182 of the lower member 172 coincides with the notch 44 of the door stopper 40.

When the lower member 172 is rotated by a predetermined angle about the lower pin 53 in this manner, the position of the projection 181 provided on the lower member 172 is changed around the lower pin 53, and the projection 181 of the lower member 172 faces the step portion 174 of the step portion 175 provided on the upper member 171 and having a different projection height. At this time, the n projections 181 provided on the lower member 172 face the step portions 174 of the n step portions 175 provided on the upper member 171, which have the same height.

When the lifting of the right door 11 is completed and the weight of the right door 11 is supported by the lower hinge portion 50, the protrusion 181 of the lower member 172 comes into contact with the upper member 171 at the step 174 having a different projection height from that before the lower member 172 is rotated. That is, in the present embodiment, if the lower member 172 is rotated about the lower pin 53, the contact position between the step portion 174 of the upper member 171 and the projection 181 of the lower member 172 changes in the vertical direction. Accordingly, the contact position between the adjusting portion 170 and the lower surface of the right door 11 is changed in the vertical direction, and the vertical position of the right door 11 with respect to the refrigerator main body 2 can be adjusted.

As in the first embodiment, in the refrigerator 1 of the present embodiment, even after the user sets the refrigerator 1, the user can easily correct the vertical positional deviation of the left door 10 and the right door 11, the external appearance quality can be maintained well, the vertical position of the right door 11 with respect to the refrigerator main body 2 can be changed in stages, the upper member 171 and the lower member 172 can be brought into contact with each other at a plurality of locations around the lower pin 53, and the right door 11 can be supported stably with the rattling suppressed.

In the present embodiment, the upper member 171 and the lower member 172 are provided with: the rotation stop protrusion 176 and the rotation stop recess 178, therefore, there is no: when the door is opened or closed, the contact position between the step 174 of the upper member 171 and the projection 181 of the lower member 172 changes, and there is no possibility that: the vertical position of the right door 11 is unexpectedly changed.

Other structures, operations, and effects are the same as those of the first embodiment, and detailed description thereof is omitted.

(modification of the second embodiment)

In the second embodiment, the upper member 171 is provided with the stepped portion 175 including the plurality of stepped portions 174, and the lower member 172 is provided with the projection 181, but the upper member 171 may be provided with the projection, and the lower member 172 may be provided with: one or more step portions having different protrusion heights. The step 174 provided on the upper member 171 and the lower member 172 may be of 1 stage or may be of multiple stages.

In the second embodiment, the case where two stepped portions 175 and two projections 181 are provided has been described, but one or three or more stepped portions 175 and projections 181 may be provided.

In the second embodiment, the case where the jig engaging portion 180 is provided in a polygonal cross section has been described, but it may be provided in the lower portion of the side surface of the lower member 172: for example, a recessed portion shape recessed in the horizontal direction, and the lower member 172 is rotated around the lower pin 53 by a rotating jig fitted into the recessed portion shape.

In the second embodiment, the detent protrusion 176 is provided on the upper member 171 and the detent recess 178 is provided on the lower member 172, but the detent protrusion may be provided on the upper member 171 and the detent recess 178 may be provided on the lower member 172: and a projection fitted into a recess provided in the upper member 171.

(third embodiment)

The third embodiment will be described mainly with reference to fig. 14 to 17, focusing on a part different from the first embodiment. The same components as those in the first embodiment are denoted by the same reference numerals, and detailed description thereof is omitted.

As shown in fig. 14 and 15, the lower hinge portion 250 is formed by molding a metal, for example, a steel plate, into a predetermined shape. The lower hinge portion 250 includes: a fixing portion 251 fixed to a front end portion 8 of a partition wall between refrigerating compartment 3 and vegetable compartment 5 by screws or the like; and a shaft support portion 252 bent so as to protrude substantially horizontally forward from the fixing portion 251. The shaft support portion 252 includes: an engaging hook 254 projecting horizontally forward, and a cylindrical portion 255 projecting upward.

The barrel 255 appears as: the inner side of the hollow part is provided with two upper and lower stepped cylinders with two hollow parts with different inner diameters. Specifically, the cylindrical portion 255 includes: a first cylindrical portion 255a provided on the upper side (the front end side); a second cylindrical portion 255b arranged coaxially with the first cylindrical portion 255a on the lower side (the shaft support portion 252 side) of the first cylindrical portion 255 a; and a stepped portion 255c provided between the first cylindrical portion 255a and the second cylindrical portion 255 b. The inner diameter of the first cylindrical portion 255a is set larger than the inner diameter of the second cylindrical portion 255 b.

The outer diameter of the cylindrical portion 255 is set such that: is slightly smaller than the inner diameter of the door hole 37 provided in the lower door cover 27. The cylindrical portion 255 is inserted into the door hole 37 provided in the lower door cover 27 in a state where the adjustment portion 270 is housed in a hollow portion formed inside the cylindrical portion 255. When the cylindrical portion 255 is inserted into the door hole 37, a predetermined gap is secured between the door hole 37 and the cylindrical portion 255, and the right door 11 is slidable in the vertical direction with respect to the cylindrical portion 255.

As shown in fig. 16, the adjustment unit 270 includes: an upper member 271 fixed to the upper portion of the lower pin 253, and a lower member 272 provided with an insertion hole 279 through which the lower pin 253 is inserted. The adjustment unit 270 is configured to: when the lower pin 253 is inserted into the insertion hole 279, the upper member 271 is overlapped on the upper side of the lower member 272.

The upper member 271 is formed by molding a synthetic resin such as polyacetal resin into a predetermined shape, and has a shape protruding radially outward from the lower pin 253. For example, the upper member 271 is disposed coaxially with the lower pin 253, and the upper member 271 is constituted by a cylindrical member having an outer diameter larger than that of the lower pin 253.

On the lower surface of the upper member 271, there are provided: and a protrusion 281 surrounding the lower pin 253 and protruding downward. In the present embodiment, n (n is an integer of 2 or more, and 2 in the present embodiment) protrusions 281 are provided at predetermined intervals so as to be symmetrical around the lower pin 253. The n protrusions 281 are all set to the same height (projection amount), and the lower surface of each protrusion 281 is formed as a horizontal surface (a surface perpendicular to the axial direction of the lower pin 253).

At least one of the n protrusions 281 provided on the upper member 271 is provided with: a rotation stop protrusion 276 protruding downward. In the present embodiment, the rotation preventing protrusion 276 is described as being formed in a convex stripe shape extending along the radial direction of the lower pin 253, but may be in a columnar shape, a hemispherical shape, or the like.

As shown in fig. 17, a lower portion of a lower pin 253 fixed to an upper member 271 is provided with: a mark 282, and a jig engaging portion 280 that engages with an adjustment jig 290 described later. The jig engagement portion 280 is formed of a recess having a polygonal cross section (hexagonal shape in the present embodiment) provided on the bottom surface of the lower pin 253, for example. The mark 282 is provided with: at a position corresponding to the protrusion 281 provided on the upper member 271.

The lower member 272 is formed by molding a synthetic resin such as polypropylene into a predetermined shape. The lower member 272 includes: the head 272a, the shaft 272b provided below the head 272a, and the insertion hole 279 through which the head 272a and the shaft 272b vertically pass, wherein the head 272a has an outer diameter: is larger than the outer diameter of the shaft portion 272 b.

The insertion hole 279 is configured to: is slightly larger than the outer diameter of the lower pin 253 extending downward from the upper member 271. When the lower pin 253 is inserted into the insertion hole 279, the lower surface of the upper member 271 abuts against the upper surface of the head 272a of the lower member 272, and the upper member 271 is arranged to overlap the upper side of the lower member 272. A predetermined gap is formed between the lower pin 253 and the insertion hole 279, and the lower pin 253 is disposed in the insertion hole 279 in a state of being able to rotate around the axis.

The lower pin 253 disposed in the insertion hole 297 is disposed coaxially with the upper pin 33 provided in the upper support 22 in the vertical direction. The distance between the lower pin 253 and the upper pin 33, that is, the distance from the upper surface of the shaft support 252 provided with the cylindrical portion 255 to the lower surface of the protruding portion 36 provided with the upper pin 33 is set to: is longer than the vertical length of the right door 11. Accordingly, the upper support portion 22 and the lower support portion 23 support the right door 11 so as to be pivotable about the upper pin 33 and the lower pin 253, and also support the right door 11 so as to be movable in the vertical direction.

On the upper surface of the head 272a, n steps 275 are provided around the lower pin 253. The step portion 275 is formed by a plurality of step portions 274 whose protruding heights protruding upward from the upper surface of the head portion 272a vary sequentially around the lower pin 253. The upper surface of the step portion 274 constituting the step portion 275 becomes: a horizontal surface vertically opposed to the upper member 271. On the upper surfaces of the plurality of stepped portions 274, rotation stop recessed portions 278 are provided, and rotation stop protruding portions 276 provided on the protrusions 281 of the upper member 271 are fitted into the rotation stop recessed portions 278.

In addition, in the example shown in fig. 16, there are shown: in the case where the detent convex portions 276 and the detent concave portions 278 are provided only in a part of the protrusions 281 and a part of the step portions 275 out of the n protrusions 281 and the n step portions 275 provided around the lower pin 253, all of the n protrusions 281 and the n step portions 275 provided around the lower pin 253 may be provided with: detent protrusion 276 and detent recess 278.

As shown in fig. 17, marks 284 are provided on the lower surface of the shaft portion 272b of the lower member 272 so as to correspond to the respective step portions 274 constituting the step portion 275. Specifically, "3" is displayed at the position corresponding to the stepped portion 74 having the highest projection height, and "2", "1", and "0" are displayed at the positions corresponding to the second, third, and fourth stepped portions 74, respectively.

When the shaft portion 272b of the lower member 272 is inserted into the second cylindrical portion 255b of the lower hinge portion 250, the lower surface of the head portion 272a of the lower member 272 abuts against the stepped portion 255c of the cylindrical portion 255, and the lower member 272 is disposed inside the cylindrical portion 255. At this time, the convex portion 273 protruding radially outward provided on the outer peripheral surface of the head portion 272a is inserted into: a slit 256 extending in the vertical direction is provided in the cylindrical portion 255. Thus, the lower member 272 is accommodated in the cylindrical portion 255 in a state of restricting the rotation about the axis.

As shown in fig. 15, when the adjustment portion 270 is housed in the cylindrical portion 255 of the lower hinge portion 250, the upper surface of the upper member 271 protrudes upward beyond the upper end of the cylindrical portion 255. Therefore, when the cylindrical portion 255 is inserted into the door hole 37, the upper surface of the upper member 271 abuts against the bottom 37a of the door hole 37 provided in the lower door cover 27, and the upper member 271 is pressed against the lower member 272 by the weight of the right door 11.

When the upper member 271 is pressed against the lower member 272, the detent protrusion 276 provided on the upper member 271 engages with the detent recess 278 provided on the lower member 272. Thus, the rotation stop protrusion 276 and the rotation stop recess 278 function as a prohibition portion that prohibits: one of the lower member 272 and the upper member 271 is rotatable about the lower pin 253 with respect to the other.

When the rotation stop protrusion 276 is engaged with the rotation stop recess 278, as shown in fig. 17, one of the marks 282 provided on the bottom surface of the lower pin 253 and the mark 284 provided on the lower member 272 coincides with the radial direction of the lower pin 253. The user can visually recognize these

marks

282 and 284 by looking down the cylindrical portion 255 of the lower hinge portion 250 from below. Thus, the user can confirm that: the projection 281 of the upper member 271 is in contact with any one of the plurality of step portions 274 constituting the step portion 275 of the lower member 272.

In the refrigerator 1 having such a configuration, since the rotation of the lower member 272 around the axis is restricted in the cylindrical portion 255, the rotation of the upper member 271 in which the detent protrusion 276 engages with the detent recess 278 around the axis is also restricted in the cylindrical portion 255, as in the case of the lower member 272. Therefore, when the right door 11 is opened or closed, the right door 11 rotates about the lower pin 253 while rubbing against the bottom 37a of the door hole 37 of the lower door cover 27 and the upper surface of the upper member 271.

First, the right door 11 is lifted upward with the weight of the right door 11 supported by the lower hinge portion 50. When the right door 11 is lifted upward, the right door 11 releases the pressing of the upper member 271.

Then, the adjustment jig 290 is engaged with the jig engaging portion 280 of the lower pin 253, and the lower pin 253 is further pivoted by a predetermined angle while being pushed up by the adjustment jig 290 until the mark 282 of the lower pin 253 matches the mark 284 of the lower member 272.

As described above, when the lower pin 253 is pivoted by a predetermined angle, the upper member 271 fixed to the upper portion of the lower pin 253 pivots about the lower pin 253, so that the position of the projection 281 provided on the lower member 272 is changed around the lower pin 253, and the projection 281 of the upper member 271 faces the step portion 274 of the step portion 275 provided on the lower member 272, which has a different projection height. At this time, the n protrusions 281 provided on the upper member 271 face the step portions 274 having the same height as the n step portions 275 provided on the lower member 272.

When the adjustment jig 290 is removed from the lower pin 253 and the push-up of the lower pin 253 is completed, the projection 281 of the upper member 271 comes into contact with the head 272a of the lower member 272 at the step 274 having a different projection height from that before the rotation of the lower pin 253.

When the lifting of right door 11 is completed and the weight of right door 11 is supported by lower hinge portion 50, bottom 37a of door hole 37 of lower door cover 27 is supported by the upper surface of upper member 271.

That is, in the present embodiment, if the upper member 271 is rotated together with the lower pin 253 about the lower pin 253, the contact position between the protrusion 281 of the upper member 271 and the step portion 274 of the lower member 272 changes in the vertical direction, and the position of the upper surface of the upper member 271 in the vertical direction also changes. In this way, the contact position between the adjusting portion 270 and the lower surface of the right door 11 is changed in the vertical direction, thereby adjusting the vertical position of the right door 11 with respect to the refrigerator main body 2.

As in the first and second embodiments, in the refrigerator 1 of the present embodiment, even after the refrigerator 1 is installed, the user can easily correct the vertical positional deviation of the left door 10 and the right door 11, can maintain the appearance quality well, can change the vertical position of the right door 11 with respect to the refrigerator main body 2 in stages, can bring the upper member 171 and the lower member 172 into contact at a plurality of locations around the lower pin 53, and can stably support the right door 11 while suppressing the rattling.
