Description

本発明の実施形態は、冷蔵庫に関するものである。 Embodiments of the present invention relate to a refrigerator.

冷蔵庫は、扉の上部と下部に設けられた下側支持部と上側支持部に支持された回動式の扉によって、冷蔵庫本体の内部に形成された貯蔵室の前面開口部が閉塞されている。 In the refrigerator, a front opening of a storage chamber formed inside the refrigerator main body is closed by a pivotable door supported by lower and upper supporting portions provided at upper and lower portions of the door. ..

回動式の扉を備える冷蔵庫では、冷蔵庫の設置面が傾斜したり、扉の収納スペースに重量の大きい収納物が収納されると、冷蔵庫本体に歪みが生じるため、扉が所定位置から上下方向にズレて配置される。特に、扉が左右に分割された観音開き式の扉では、扉の上下方向のズレが、左右の扉の反枢支側の突き合わせ部位に段差となって現れ、外観品位を大きく損ねるおそれがある。 In a refrigerator equipped with a swingable door, when the refrigerator installation surface is inclined or a large storage item is stored in the storage space of the door, the refrigerator body is distorted, so that the door moves vertically from the predetermined position. It is displaced. Particularly, in a double-door type door in which the door is divided into left and right, a vertical shift of the door may appear as a step at the abutting portions of the left and right doors on the opposite pivotal support side, greatly impairing the appearance quality.

冷蔵庫の設置時に前足の高さ調整によって冷蔵庫本体の傾きを補正することで、扉の位置ズレを抑えることも可能である。しかし、前足の高さ調整では扉の上下方向の位置を直接的に調整することができず、調整作業が煩雑であったり、調整代が小さく十分に調整することができないことがある。 By adjusting the height of the front legs when the refrigerator is installed to correct the inclination of the refrigerator body, it is possible to suppress the positional deviation of the door. However, in the height adjustment of the forefoot, the vertical position of the door cannot be directly adjusted, and the adjustment work may be complicated, or the adjustment allowance may be small and cannot be sufficiently adjusted.

なお、下記特許文献1には、冷蔵庫本体側に形成したネジ孔に螺合するヒンジ軸を回転させることにより、ヒンジ軸の高さを調節して、扉の上下方向の位置を調整することが開示されている。特許文献1の冷蔵庫では、ヒンジ軸の回転を抑制する回り止めを設ける必要があるため、冷蔵庫の組み立て時に扉の上下方向の位置を調整することができるが、扉を支持した状態でヒンジ軸の高さを調整することができず、使用者が冷蔵庫を設置した後に扉の上下方向の位置を調整することができるものではない。 In Patent Document 1 below, by rotating a hinge shaft that is screwed into a screw hole formed on the refrigerator body side, the height of the hinge shaft can be adjusted and the vertical position of the door can be adjusted. It is disclosed. In the refrigerator of Patent Document 1, since it is necessary to provide a detent for suppressing the rotation of the hinge shaft, the vertical position of the door can be adjusted when the refrigerator is assembled. The height cannot be adjusted, and the user cannot adjust the vertical position of the door after installing the refrigerator.

特開2005−337705号公報JP, 2005-337705, A

そこで、使用者が冷蔵庫を設置した後でも扉の上下方向の位置を簡単に調整することができる冷蔵庫を提供することを目的とする。 Therefore, an object of the present invention is to provide a refrigerator in which the user can easily adjust the vertical position of the door even after installing the refrigerator.

このような構成において、上側支持部22及び下側支持部23が右扉11を支持した通常状態では、下ヒンジ部50によって右扉11の重量を支持する。そのため、図4に示すように、右扉11の自重により上側部材71が下側部材72に押圧されている。右扉11の自重により上側部材71が下側部材72に押圧されると、上側部材71に設けられた突起81は、下側部材72に設けられた階段部75の傾斜面74a1、74b1、74c1、74d1のいずれか1つに押し付けられる。突起81は、傾斜面74a1、74b1、74c1、74d1の傾きによって突出面74a2、74b2、74c2、74d2へ案内され、傾斜面74a1、74b1、74c1、74d1と突出面74a2、74b2、74c2、74d2との間に嵌まり込み、上側部材71が下側部材72と係合する。 In such a configuration, in a normal state in which the upper support portion 22 and the lower support portion 23 support the right door 11, the lower hinge portion 50 supports the weight of the right door 11. Therefore, as shown in FIG. 4, the upper member 71 is pressed against the lower member 72 by the weight of the right door 11. When the upper member 71 is pressed against the lower member 72 by the own weight of the right door 11, the projection 81 provided on the upper member 71 causes the sloped surfaces 74a1, 74b1, 74c1 of the staircase portion 75 provided on the lower member 72. , 74d1. The protrusion 81 is guided to the protruding surfaces 74a2, 74b2, 74c2, 74d2 by the inclination of the inclined surfaces 74a1, 74b1, 74c1, 74d1 and is divided into the inclined surfaces 74a1, 74b1, 74c1, 74d1 and the protruding surfaces 74a2, 74b2, 74c2, 74d2. The upper member 71 is engaged with the lower member 72 by fitting in between.

このように上側部材71が下側部材72と係合すると、下側部材72は上側部材71に対して下側ピン53の軸回りに回転するのを禁止される。つまり、本実施形態において、突起81、傾斜面74a1、74b1、74c1、74d1及び突出面74a2、74b2、74c2、74d2は、下側部材72及び上側部材71の一方が他方に対して下側ピン53の軸回りに回転するのを禁止する禁止部として機能する。
そのため、本実施形態の冷蔵庫1では、右扉11の開閉時に上側部材71が下側ピン53の周りを回動すると、下側部材72も上側部材71と一緒に下側ピン53の周りを回動する。そして、右扉11は、右扉11の上下方向の位置が変化することなく一定の高さを維持したまま下側ピン53の周りを回動する。
When the upper member 71 engages with the lower member 72 in this manner, the lower member 72 is prohibited from rotating around the axis of the lower pin 53 with respect to the upper member 71. That is, in the present embodiment, in the projection 81, the inclined surfaces 74a1, 74b1, 74c1, 74d1 and the protruding surfaces 74a2, 74b2, 74c2, 74d2, one of the lower member 72 and the upper member 71 is lower than the other pin 53. It functions as a prohibition unit that prohibits rotation around the axis of.
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 rotates around the lower pin 53 together with the upper member 71. Move. Then, the right door 11 rotates around the lower pin 53 while maintaining a constant height without changing the vertical position of the right door 11.

また、上側部材71が下側部材72と係合すると、下側部材72のフランジ部83に設けられた目印82の1つが、ドアストッパ40の基部41に設けられた切欠部44と上下に一致する。使用者は、図5に示すように、ドアストッパ40の筒部42に下側ピン53が挿入され、右扉11を下側支持部23に支持させたまま上方へ持ち上げると、ドアストッパ40の切欠部44及び下側部材72の目印82を斜め上方から目視することができる。これにより、下側支持部23で右扉11を支持した状態で上側部材71の突起81が、下側部材72の階段部75を構成する複数の段部のいずれの段部と上下に対向しているのかを、確認することができる。 When the upper member 71 engages 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 cutout portion 44 provided on the base portion 41 of the door stopper 40. To do. As shown in FIG. 5, the user inserts the lower pin 53 into the tubular portion 42 of the door stopper 40 and lifts the right door 11 upward while keeping the right door 11 supported by the lower support portion 23. The notch 44 and the mark 82 of the lower member 72 can be seen from diagonally above. As a result, the protrusion 81 of the upper member 71 vertically opposes any step of the plurality of steps that configure the stepped portion 75 of the lower member 72 while the lower support 23 supports the right door 11. You can check if you are.

次に、冷蔵庫本体2に対する右扉11の上下方向の位置を調整する方法について説明する。 Next, a method of adjusting the vertical position of the right door 11 with respect to the refrigerator body 2 will be described.

まず、下ヒンジ部50が右扉11の重量を支持する状態から、右扉11を上方へ持ち上げる。右扉11を上方へ持ち上げると、右扉11に固定されたドアストッパ40が上方へ移動するため、ドアストッパ40に一体に設けられた上側部材71も上方へ移動して上側部材71と下側部材72との係合が解除される(図5参照)。 First, from the state where the lower hinge portion 50 supports the weight of the right door 11, the right door 11 is lifted upward. When the right door 11 is lifted upward, the door stopper 40 fixed to the right door 11 moves upward, so that the upper member 71 integrally provided with the door stopper 40 also moves upward and the upper member 71 and the lower side. The engagement with the member 72 is released (see FIG. 5).

そして、上側部材71と下側部材72との係合が解除された状態で、調整治具90を下側部材72の治具係合部80に係合させ、下側部材72の目印82がドアストッパ40の切欠部44と一致するまで、調整治具90を使って下側部材72を下側ピン53の周りに所定角度回動させる。 Then, with the upper member 71 and the lower member 72 disengaged, the adjusting jig 90 is engaged with the jig engaging portion 80 of the lower member 72, and the mark 82 of the lower member 72 is The lower member 72 is rotated around the lower pin 53 by a predetermined angle by using the adjusting jig 90 until it coincides with the cutout portion 44 of the door stopper 40.

このように下側部材72を下側ピン53の周りに所定角度回動させると、下側部材72に設けられた階段部75の位置が下側ピン53の周りで変更され、上側部材71の突起81が、下側部材72に設けられた階段部75の異なる突出高さの段部74a、74b、74c、74dと対向する。その際、上側部材71に設けられたn個の突起81は、下側部材72に設けられたn個の階段部75の同じ高さの段部74a、74b、74c、74dと対向するようになっている。 When the lower member 72 is rotated about the lower pin 53 by a predetermined angle in this manner, the position of the staircase portion 75 provided on the lower member 72 is changed around the lower pin 53, and the upper member 71 is rotated. The protrusion 81 faces the stepped portions 74a, 74b, 74c, 74d of the stepped portion 75 provided on the lower member 72 and having different protruding heights. At that time, the n projections 81 provided on the upper member 71 face the stepped portions 74a, 74b, 74c, 74d of the same height of the n stepped portions 75 provided on the lower member 72. Has become.

そして、下側部材72を下側ピン53の周りに所定角度回動させた後、右扉11の持ち上げを終了して右扉11の重量を下ヒンジ部50に支持させる。すると、上側部材71の突起81は、下側部材72を回動する前と異なる突出高さの段部74a、74b、74c、74dにおいて下側部材72と接触する。つまり、本実施形態では、下側部材72を下側ピン53の周りに回動させると、上側部材71の突起81と下側部材72の段部74a、74b、74c、74dとの接触位置が上下方向で変化する。これにより、調整部70と右扉11の下面との接触位置が上下方向において変更され、冷蔵庫本体2に対する右扉11の上下方向の位置を調整することができる。 Then, after rotating the lower member 72 around the lower pin 53 by a predetermined angle, 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. Then, the protrusion 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 projecting heights from those before the lower member 72 is rotated. That is, in this embodiment, when the lower member 72 is rotated around the lower pin 53, the contact position between the protrusion 81 of the upper member 71 and the stepped portions 74a, 74b, 74c, 74d of the lower member 72 is changed. It changes in the vertical direction. As a result, the contact position between the adjustment unit 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 body 2 can be adjusted.

以上のように本実施形態の冷蔵庫1では、上側支持部22と下側支持部23との間で右扉11を支持した状態で、冷蔵庫本体2に対する右扉11の上下方向の位置を調整することができる。そのため、使用者が冷蔵庫1を設置した後でも左扉10及び右扉11の上下方向の位置ズレを簡単に修正することができ、外観品位を良好に保持することができる。 As described above, in the refrigerator 1 of the present embodiment, the vertical position of the right door 11 with respect to the refrigerator body 2 is adjusted with the right door 11 supported between the upper support 22 and the lower support 23. be able to. Therefore, even after the user installs the refrigerator 1, it is possible to easily correct the positional deviation of the left door 10 and the right door 11 in the vertical direction, and it is possible to maintain good appearance quality.

本実施形態では、下側部材72に設けられた段部74a、74b、74c、74dが、下側ピン53の周りで突出高さが順次変化する階段部75を構成しているため、冷蔵庫本体2に対する右扉11の上下方向の位置を段階的に変化させることができる。 In the present embodiment, since the stepped portions 74a, 74b, 74c, 74d provided on the lower member 72 constitute the staircase portion 75 in which the protruding height is sequentially changed around the lower pin 53, the refrigerator main body The vertical position of the right door 11 with respect to 2 can be changed stepwise.

本実施形態では、上側部材71及び下側部材72に、n個の階段部75及びn個の突起81が設けられ、n個の突起81が、下側部材72に設けられたn個の階段部75の同じ突出高さの段部74a、74b、74c、74dと対向するようになっている。そのため、下側ピン53の周りの複数箇所において上側部材71と下側部材72を接触させることができ、がたつきを抑えて右扉11を安定的に支持することができる。 In the present embodiment, the upper member 71 and the lower member 72 are provided with n stairs 75 and n projections 81, and the n projections 81 are n stairs provided on the lower member 72. The portion 75 faces the stepped portions 74a, 74b, 74c, 74d having the same protruding height. 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 rattling can be suppressed, and the right door 11 can be stably supported.

また、本実施形態では、階段部75を構成する段部74a、74b、74c、74dが、突出高さの低い段部74b、74c、74dへ向かって突出高さが漸次小さくなるように傾斜する傾斜面74a1、74b1、74c1、74d1と、傾斜面74a1、74b1、74c1、74d1における突出高さの低い側から突出する突出面74a2、74b2、74c2、74d2とを備える。そのため、右扉11を持ち上げながら下側部材72を下側ピン53の周りに回動させた時に、上側部材71の突起81と下側部材72の段部74a、74b、74c、74dとの位置が上下に正確に一致していなくても、右扉11の重量を下ヒンジ部50に支持させると、突起81が傾斜面74a1、74b1、74c1、74d1の傾きによって突出面74a2、74b2、74c2、74d2へ案内され、傾斜面74a1、74b1、74c1、74d1と突出面74a2、74b2、74c2、74d2との間に嵌まり込み、上側部材71と下側部材72とを確実に係合させることができる。 Further, in the present embodiment, the stepped portions 74a, 74b, 74c, 74d forming the staircase portion 75 are inclined so that the projecting height gradually decreases toward the stepped portions 74b, 74c, 74d having the low projecting height. The inclined surfaces 74a1, 74b1, 74c1, 74d1 and the protruding surfaces 74a2, 74b2, 74c2, 74d2 protruding from the lower protruding height side of the inclined surfaces 74a1, 74b1, 74c1, 74d1 are provided. Therefore, when the lower member 72 is rotated around the lower pin 53 while lifting the right door 11, the positions of the protrusion 81 of the upper member 71 and the stepped portions 74a, 74b, 74c, 74d of the lower member 72. Even if the upper and lower sides are not exactly aligned with each other, when the weight of the right door 11 is supported by the lower hinge part 50, the protrusion 81 causes the inclined surfaces 74a1, 74b1, 74c1, 74d1 to incline, and the protruding surfaces 74a2, 74b2, 74c2, It is guided to 74d2 and fits between the inclined surfaces 74a1, 74b1, 74c1, 74d1 and the projecting surfaces 74a2, 74b2, 74c2, 74d2, and the upper member 71 and the lower member 72 can be reliably engaged. ..

しかも、上側部材71が下側部材72と係合すると、下側部材72は上側部材71に対して下側ピン53の軸回りに回転するのを禁止されるため、右扉11の上下方向の位置が不意に変化することがない。 Moreover, when the upper member 71 engages with the lower member 72, the lower member 72 is prohibited from rotating around the axis of the lower pin 53 with respect to the upper member 71, so that the vertical direction of the right door 11 is increased.

The protrusion 181 faces the step portion 174 of the stepped portion 175 provided on the upper member 171 and having a different protruding height. At that time, the n protrusions 181 provided on the lower member 172 are arranged to face the step portions 174 of the same height of the n stairway portions 175 provided on the upper member 171.

そして、右扉11の持ち上げを終了して右扉11の重量を下ヒンジ部50に支持させると、下側部材172の突起181は、下側部材172を回動する前と異なる突出高さの段部174において上側部材171と接触する。つまり、本実施形態では、下側部材172を下側ピン53の周りに回動させると、上側部材171の段部174と下側部材172の突起181との接触位置が上下方向で変化する。これにより、調整部170と右扉11の下面との接触位置が上下方向において変更され、冷蔵庫本体2に対する右扉11の上下方向の位置を調整することができる。 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 has a protrusion height different from that before rotating the lower member 172. It contacts the upper member 171 at the step 174. That is, in the present embodiment, when the lower member 172 is rotated around the lower pin 53, the contact position between the step 174 of the upper member 171 and the protrusion 181 of the lower member 172 changes in the vertical direction. As a result, the contact position between the adjusting unit 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 body 2 can be adjusted.

The mark 282 is provided at a position corresponding to the protrusion 281 provided on the upper member 271.

下側部材272は、ポリプロピレンなどの合成樹脂を所定形状に成形してなる。下側部材272は、頭部272aと、頭部272aの下側に設けられた軸部272bと、頭部272a及び軸部272bを上下に貫通する挿通孔279とを備え、頭部272aの外径が軸部272bの外径より大きく設けられている。 The lower member 272 is formed by molding a synthetic resin such as polypropylene into a predetermined shape. The lower member 272 includes a head portion 272a, a shaft portion 272b provided below the head portion 272a, and an insertion hole 279 that vertically penetrates the head portion 272a and the shaft portion 272b. The diameter is larger than the outer diameter of the shaft portion 272b.

挿通孔279は、上側部材271から下方へ延びる下側ピン253の外径より若干大きく設けられている。挿通孔279に下側ピン253を挿通すると、上側部材271の下面が下側部材272の頭部272aの上面に当接し、上側部材271が下側部材272の上側に重ねて配置される。下側ピン253と挿通孔279との間には、所定のクリアランスが形成され、軸回りに回転可能な状態で下側ピン253が挿通孔279に配置される。 The insertion hole 279 is provided 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 through the insertion hole 279, the lower surface of the upper member 271 abuts on the upper surface of the head portion 272a of the lower member 272, and the upper member 271 is arranged so as to overlap with the upper side of the lower member 272. A predetermined clearance is formed between the lower pin 253 and the insertion hole 279, and the lower pin 253 is arranged in the insertion hole 279 so as to be rotatable about the axis.

挿通孔297に配置された下側ピン253は、上側支持部22に設けられた上側ピン33と上下に同軸状に配置されている。下側ピン253と上側ピン33との間隔、つまり、筒部255が設けられた軸支持部252の上面から上側ピン33が設けられた突出部36の下面までの距離は、右扉11の上下方向の長さより大きく設けられている。これにより、上側支持部22と下側支持部23は、上側ピン33と下側ピン253の軸回りに右扉11を回動可能に支持するとともに、右扉11を上下方向に移動可能に支持する。 The lower pin 253 arranged in the insertion hole 297 is arranged 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 portion 252 provided with the tubular portion 255 to the lower surface of the projecting portion 36 provided with the upper pin 33 is the upper and lower sides of the right door 11. It is larger than the length in the direction. Accordingly, the upper support 22 and the lower support 23 support the right door 11 rotatably around the axes of 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. To do.

頭部272aの上面には、下側ピン253の周りにn個の階段部275が設けられている。階段部275は、頭部272aの上面から上方へ向けて突出する突出高さが下側ピン253の周りで順次変化する複数の段部274から構成されている。階段部275を構成する段部274の上面は、上側部材271と上下に対向する水平な面をなしている。複数の段部274の上面には、上側部材271の突起281に設けられた回り止め凸部276が嵌まり込む回り止め凹部278が設けられている。 On the upper surface of the head 272a, n stairs 275 are provided around the lower pin 253. The staircase portion 275 is composed of a plurality of stepped portions 274 in which the protruding height protruding upward from the upper surface of the head portion 272 a is sequentially changed around the lower pin 253. The upper surface of the stepped portion 274 forming the staircase portion 275 is a horizontal surface that vertically faces the upper member 271. On the upper surface of the plurality of stepped portions 274, a detent recess 278 into which the detent protrusion 276 provided on the protrusion 281 of the upper member 271 is fitted is provided.

なお、図16に示す例では、下側ピン253の周りに設けられたn個の突起281及びn個の階段部275のうち、一部の突起281及び一部の階段部275のみに回り止め凸部276及び回り止め凹部278を設ける場合を示したが、下側ピン253の周りに設けられたn個の突起281及びn個の階段部275の全てに回り止め凸部276及び回り止め凹部278を設けてもよい。 In the example shown in FIG. 16, among the n projections 281 and n stairs 275 provided around the lower pin 253, only some projections 281 and some stairs 275 are prevented from rotating. Although the case where the convex portion 276 and the anti-rotation concave portion 278 are provided is shown, the anti-rotation convex portion 276 and the anti-rotation concave portion are provided on all of the n projections 281 and the n step portions 275 provided around the lower pin 253. 278 may be provided.

また、下側部材272の軸部272bの下面には、図17に示すように、階段部275を構成する複数の段部274にそれぞれ対応して目印284が設けられている。具体的には、最も突出高さの高い段部74の対応する位置に「3」が表示され、2番目、3番目及び4番目に高い段部74の対応する位置に、それぞれ「2」、「1」及び「0」が表示されている。 Further, 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 plurality of step portions 274 forming the staircase portion 275, respectively. Specifically, “3” is displayed at the corresponding position of the step portion 74 having the highest protrusion height, and “2” is displayed at the corresponding position of the second, third, and fourth highest step portions 74, respectively. "1" and "0" are displayed.

下側部材272の軸部272bを下ヒンジ部250の第2筒部255bに挿入すると、下側部材272は、頭部272aの下面が筒部255の段部255cに当接し、筒部255の内側に配置される。その際、頭部272aの外周面に設けられた径方向外方へ突出する凸部273が、筒部255に設けられた上下方向に延びるスリット256に挿入される。これより、下側部材272は、軸回りの回転が制限された状態で筒部255内に収納される。 When the shaft portion 272b of the lower member 272 is inserted into the second tubular portion 255b of the lower hinge portion 250, the lower member 272 has the lower surface of the head portion 272a abutting on the step portion 255c of the tubular portion 255 and the tubular portion 255 It is placed inside. At that time, the convex portion 273 provided on the outer peripheral surface of the head portion 272 a and protruding outward in the radial direction is inserted into the slit 256 provided in the cylindrical portion 255 and extending in the vertical direction. As a result, the lower member 272 is housed in the tubular portion 255 in a state where the rotation around the axis is restricted.

図15に示すように、下ヒンジ部250の筒部255に調整部270を収納した時に、上側部材271の上面は、筒部255の上端より上方に突出する。そのため、扉穴37に筒部255を挿入すると、上側部材271の上面が、下側扉キャップ27に設けられた扉穴37の底部37aに当接し、右扉11の自重により上側部材271が下側部材272に押圧されている。 As shown in FIG. 15, when the adjusting portion 270 is housed in the tubular portion 255 of the lower hinge portion 250, the upper surface of the upper member 271 projects above the upper end of the tubular portion 255. Therefore, when the tubular portion 255 is inserted into the door hole 37, the upper surface of the upper member 271 comes into contact with the bottom portion 37a of the door hole 37 provided in the lower door cap 27, and the upper member 271 is lowered by the weight of the right door 11. It is pressed by the side member 272.

上側部材271が下側部材272に押圧されると、上側部材271に設けられた回り止め凸部276が、下側部材272に設けられた回り止め凹部278と係合する。これにより、回り止め凸部276及び回り止め凹部278は、下側部材272及び上側部材271の一方が他方に対して下側ピン253の軸回りに回転するのを禁止する禁止部として機能する。 When the upper member 271 is pressed by 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. As a result, the anti-rotation protrusion 276 and the anti-rotation recess 278 function as an inhibition portion that inhibits one of the lower member 272 and the upper member 271 from rotating around the axis of the lower pin 253 with respect to the other.

回り止め凸部276が回り止め凹部278に係合すると、図17に示すように、下側ピン253の底面に設けられた目印282が、下側部材272に設けられた目印284の1つと下側ピン253の径方向に一致する。使用者が、下ヒンジ部250の筒部255を下方から見上げることで、これらの目印282,284を目視することができる。これにより、使用者は、下側支持部23で右扉11を支持したままで、上側部材271の突起281が、下側部材272の階段部275を構成する複数の段部274のいずれの段部274に接触しているのかを、確認することができる。 When the anti-rotation protrusion 276 engages with the anti-rotation recess 278, as shown in FIG. 17, the mark 282 provided on the bottom surface of the lower pin 253 and the one of the marks 284 provided on the lower member 272 and the lower mark 284 are provided. It coincides with the radial direction of the side pin 253. The user can see these marks 282, 284 by looking up at the tubular portion 255 of the lower hinge portion 250 from below. With this, the user holds the right door 11 with the lower support portion 23, and the protrusion 281 of the upper member 271 determines which step of the plurality of step portions 274 that constitutes the step portion 275 of the lower member 272. It can be confirmed whether or not it is in contact with the portion 274.

このような構成の冷蔵庫1では、下側部材272が、筒部255内において軸回りの回転が制限されているため、回り止め凸部276が回り止め凹部278に係合した上側部材271も、下側部材272と同様、筒部255内において軸回りの回転が制限される。そのため、右扉11は、右扉11の開閉時に、下側扉キャップ27の扉穴37の底部37aと上側部材271の上面と擦れ合いながら下側ピン253の周りを回動する。 In the refrigerator 1 having such a configuration, since the lower member 272 is restricted from rotating about the axis in the tubular portion 255, the upper member 271 in which the rotation preventing convex portion 276 engages with the rotation preventing concave portion 278 is also As with the lower member 272, rotation about the axis is restricted within the tubular portion 255. Therefore, when the right door 11 is opened and closed, the right door 11 rotates around the lower pin 253 while rubbing against the bottom portion 37a of the door hole 37 of the lower door cap 27 and the upper surface of the upper member 271.

次に、冷蔵庫本体2に対する右扉11の上下方向の位置を調整する方法について説明する。 Next, a method of adjusting the vertical position of the right door 11 with respect to the refrigerator body 2 will be described.

まず、下ヒンジ部50が右扉11の重量を支持する状態から、右扉11を上方へ持ち上げる。右扉11を上方へ持ち上げると、右扉11による上側部材271の押圧が解除される。 First, from the state where the lower hinge portion 50 supports the weight of the right door 11, the right door 11 is lifted upward. When the right door 11 is lifted upward, the pressing of the upper member 271 by the right door 11 is released.

そして、調整治具290を下側ピン253の治具係合部280に係合させ、下側ピン253の目印282が、下側部材272の目印284と一致するまで、調整治具290を使って下側ピン253を押し上げながら軸回りに所定角度回動させる。 Then, the adjusting jig 290 is engaged with the jig engaging portion 280 of the lower pin 253, and the adjusting jig 290 is used until the mark 282 of the lower pin 253 coincides with the mark 284 of the lower member 272. The lower pin 253 is pushed up and rotated about the axis by a predetermined angle.

このように下側ピン253を軸回りに所定角度回動させると、下側ピン253の上部に固定された上側部材271が下側ピン253の周りに回動するため、下側部材272に設けられた突起281の位置が下側ピン253の周りで変更され、上側部材271の突起281が、下側部材272に設けられた階段部275の異なる突出高さの段部274と対向する。その際、上側部材271に設けられたn個の突起281は、下側部材272に設けられたn個の階段部275の同じ高さの段部274と対向するようになっている。 When the lower pin 253 is rotated about the axis by a predetermined angle in this manner, the upper member 271 fixed to the upper portion of the lower pin 253 rotates around the lower pin 253. The position of the raised protrusion 281 is changed around the lower pin 253, and the protrusion 281 of the upper member 271 faces the stepped portion 274 of the stepped portion 275 provided on the lower member 272 with a different protruding height. At this time, the n projections 281 provided on the upper member 271 are arranged to face the step portions 274 of the same height of the n staircase portions 275 provided on the lower member 272.

そして、調整治具290を下側ピン253から取り外して下側ピン253の押し上げを終了すると、上側部材271の突起281が、下側ピン253を回動する前と異なる突出高さの段部274において下側部材272の頭部272aと接触する。 Then, when the adjustment jig 290 is removed from the lower pin 253 and the pushing up of the lower pin 253 is completed, the protrusion 281 of the upper member 271 has a step portion 274 having a protruding height different from that before the lower pin 253 is rotated. In contact with the head 272a of the lower member 272 at.

そして、右扉11の持ち上げを終了して右扉11の重量を下ヒンジ部50に支持させると、下側扉キャップ27の扉穴37の底部37aが上側部材271の上面に支持される。 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 bottom portion 37a of the door hole 37 of the lower door cap 27 is supported by the upper surface of the upper member 271.

つまり、本実施形態では、下側ピン253とともに上側部材271を下側ピン253の周りに回動させると、上側部材271の突起281と下側部材272の段部274との接触位置が上下方向で変化し、上側部材271の上面の上下方向の位置が変化する。このように調整部270と右扉11の下面との接触位置を上下方向において変更することで、冷蔵庫本体2に対する右扉11の上下方向の位置を調整する。 That is, in the present embodiment, when the upper member 271 is rotated around the lower pin 253 together with 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 is in the vertical direction. The vertical position of the upper surface of the upper member 271 changes. By thus changing the contact position between the adjustment unit 270 and the lower surface of the right door 11 in the vertical direction, the vertical position of the right door 11 with respect to the refrigerator body 2 is adjusted.

第1実施形態や第2実施形態と同様、本実施形態の冷蔵庫1でも、使用者が冷蔵庫1を設置した後に左扉10及び右扉11の上下方向の位置ズレを簡単に修正することができ、外観品位を良好に保持することができたり、冷蔵庫本体2に対する右扉11の上下方向の位置を段階的に変化させることができたり、下側ピン53の周りの複数箇所において上側部材171と下側部材172を接触させることができ、がたつきを抑えて右扉11を安定的に支持することができる。 Similar to the first and second embodiments, also in the refrigerator 1 of the present embodiment, the user can easily correct the vertical displacement of the left door 10 and the right door 11 after installing the refrigerator 1. , The appearance quality can be maintained well, the vertical position of the right door 11 with respect to the refrigerator body 2 can be changed stepwise, and the upper member 171 and the upper member 171 can be provided at a plurality of positions around the lower pin 53. The lower member 172 can be brought into contact, rattling can be suppressed, and the right door 11 can be stably supported.
