Description

本発明は引出し式の扉によって収納容器を出し入れする冷蔵庫に係り、特に引き出し時における収納容器のブレを低減したものに関する。   The present invention relates to a refrigerator in which a storage container is taken in and out by a drawer-type door, and particularly relates to a refrigerator that reduces blurring of the storage container when being pulled out.

近年、冷蔵庫は生活の多様化とともに収納量の大形化傾向にあり、その形態としては、上部に最も貯蔵物収納容積の大きい冷蔵室を設置し、その下部に収納容積の比較的小さい製氷室や温度切替室を幅方向の左右に区分して設け、さらにその下部に野菜室、最下部に冷凍室を設置するタイプが多くなっている。   In recent years, refrigerators have a tendency to increase in storage capacity with diversification of life. As a form, a refrigerator compartment with the largest storage capacity is installed in the upper part, and an ice making room with a relatively small storage capacity in the lower part. There are many types in which a temperature switching chamber is divided into left and right in the width direction, a vegetable room is provided at the lower part, and a freezing room is provided at the lowermost part.

前記冷蔵室は、その前面開口部近傍に一側を枢支した扉、あるいは観音開き式の扉により、前記開口を回動方式で閉塞しており、野菜室や冷凍室、および製氷室や温度切替室は、収納物の出し入れ操作の利便性から扉の貯蔵室側に収納容器を取り付け、前後に引き出し式とするものが多い。   The refrigerating room is closed in a rotating manner by a door pivoted on one side in the vicinity of the front opening or by a double door, and the vegetable room, the freezer room, the ice making room, and temperature switching In many chambers, a storage container is attached to the storage chamber side of the door and the drawer is retractable forward and backward for the convenience of taking in and out the stored items.

従来、冷蔵庫における引き出し式の扉容器構造においては、引出し式扉の縦断面図である図7に示すように、周縁に設けたガスケットにより貯蔵室本体側の受け面との間隙をシールした引出し扉(51)の内面側に貯蔵室内側へ延びて容器(55)を保持する左右一対の支持枠(53)を固定し、前記引出し扉(51)の内板(52)と容器(55)の前面との間には冷気が流れる隙間tを形成し、内板(52)には容器(55)の幅方向端部よりも内側に冷気ガイドとなる凸部(57)を上下方向に設けるとともに、前記支持枠(53)を滑車を介して貯蔵室両側に設けたレールに沿って摺動自在に配置している(特許文献1参照)。そして、開扉時において引き出された支持枠(53)は、貯蔵室の開口部近傍に設けた滑車でその下面を受け、支持枠(53)の後端に取り付けた滑車(53a)をレールで支える前後2点の支持によって引き出し状態を保持するようにしている。   Conventionally, in a drawer-type door container structure in a refrigerator, as shown in FIG. 7 which is a longitudinal sectional view of a drawer-type door, a drawer door in which a gap with the receiving surface on the storage chamber body side is sealed by a gasket provided at the periphery. A pair of left and right support frames (53) extending to the storage chamber side and holding the container (55) are fixed to the inner surface side of (51), and the inner plate (52) of the drawer door (51) and the container (55) A gap t through which cool air flows is formed between the front surface, and a convex portion (57) serving as a cool air guide is provided on the inner plate (52) inside the width direction end of the container (55) in the vertical direction. The support frame (53) is slidably disposed along rails provided on both sides of the storage chamber via a pulley (see Patent Document 1). The support frame (53) pulled out when the door is opened receives the lower surface of the support frame (53) near the opening of the storage chamber, and the pulley (53a) attached to the rear end of the support frame (53) is a rail. The pulled-out state is maintained by supporting two points before and after the support.

しかし、上記のように単一の支持枠(53)とレールとの摺動係合では、引き出し時の支持点の関係から容器(55)の引出し量に限界があり、容器(55)の奥行き寸法を短くせざるを得ず収納量が少なくなるだけでなく、容器(55)の上面開口部を全面に亙って引き出す構成にするのが困難なことから、容器(55)の後端部が庫内に残ることになり、貯蔵品の収納取り出しが煩雑になるとともに、洗浄などのために容器(55)自体を支持枠から取り外したり、また取り付ける作業がしにくい不具合があった。   However, as described above, in the sliding engagement between the single support frame (53) and the rail, there is a limit to the amount of the container (55) that can be drawn due to the support point at the time of pulling out, and the depth of the container (55). The rear end of the container (55) is not only limited in size but also reduces the amount of storage, and it is difficult to draw out the entire top opening of the container (55). However, there is a problem that it is difficult to remove and attach the container (55) from the support frame for cleaning or the like.

これに対して、図8に示すように、レール部材を固定レール(71)と移動レール(73)、さらに中間走行レール(74)を有するダブルレール方式のスライドレール(70)にし、扉支持部材に移動レール(73)を固定するとともにこれに容器(75)を係合することによって、引き出し量を大きくし、がたつきの少ない高品位な引出し扉(61)を構成した冷蔵庫が提案されている(例えば、特許文献2参照)。

On the other hand, as shown in FIG. 8, the rail member is a double rail type slide rail (70) having a fixed rail (71), a moving rail (73), and an intermediate running rail (74), and a door support member. A refrigerator has been proposed in which a moving rail (73) is fixed to the container and a container (75) is engaged with the moving rail (73) so that the amount of drawer is increased and a high-quality drawer door (61) with less rattling is configured. (For example, refer to Patent Document 2).
JP 2006-078025 A JP 2006-177653 A

しかしながら、上記特許文献2に記載の引出しレールの構成においても、引出し扉および貯蔵品を収納した容器(75)の重量は相当のものであって、その重量は扉の支持部材とスライドレール(70)で支えているものであり、引き出し量が大きいことから、依然として扉を引き出した際の左右ブレは発生し易いものであり、特に、引き出し時に扉のハンドル部を把持する位置が中央部から偏った場合には、左右へのブレが顕著に現れていた。   However, even in the configuration of the drawer rail described in Patent Document 2, the weight of the drawer (75) containing the drawer door and the storage item is considerable, and the weight is equivalent to the support member of the door and the slide rail (70). ) And the amount of pulling out is large, so it is still easy for left and right blurring to occur when the door is pulled out. In such a case, blurring to the left and right was noticeable.

本発明は上記の点に着目してなされたもので、特に補強部材を追加することのない簡単な構成で、引出し式扉により収納容器を引き出したり閉じたりする際にその左右へのブレを小さく抑制してスムーズな開閉をおこなうことができる高品位な冷蔵庫を提供することを目的とする。   The present invention has been made paying attention to the above points, and has a simple configuration that does not particularly add a reinforcing member, and when the storage container is pulled out or closed by a drawer-type door, the lateral blur is reduced. An object is to provide a high-quality refrigerator that can be smoothly opened and closed.

本発明の冷蔵庫は、貯蔵室の前面開口部を開閉自在に閉塞する引出し式の扉と、この扉の内側を形成する内板に固定され開扉とともに引き出される左右一対の支持枠と、この支持枠を保持するように前記貯蔵室両側に前後方向に亙って配置したレール部材と、前記左右の支持枠およびレール部材間に保持される収納容器とからなり、(1)前記扉の内板の下部から、前記収納容器前面へ突出する左右一対のリブ片をそれぞれ形成し、この左右一対の前記リブ片を前記収納容器に当接または近接させるか、または、(2)前記収納容器前面の下部から、前記扉の内板へ突出する左右一対のリブ片をそれぞれ形成し、この左右一対の前記リブ片を前記内板に当接または近接させる、ことを特徴とする冷蔵庫である。 The refrigerator of the present invention includes a drawer-type door that closes the front opening of the storage room so as to be openable and closable, a pair of left and right support frames that are fixed to an inner plate that forms the inside of the door, and that is pulled out together with the open door. A rail member arranged in the front-rear direction on both sides of the storage chamber so as to hold a frame, and a storage container held between the left and right support frames and the rail member, (1) an inner plate of the door A pair of left and right rib pieces projecting from the lower portion of the storage container to the front surface of the storage container, and the pair of left and right rib pieces abut or approach the storage container, or (2) the front surface of the storage container A refrigerator is characterized in that a pair of left and right rib pieces projecting from the lower part to the inner plate of the door are formed, and the pair of left and right rib pieces are brought into contact with or close to the inner plate .

本発明によれば、貯蔵食品の収納や取り出し作業を容易にするため、扉に保持した収納容器の引き出し量を大きくしても、扉の引き出し時や押し込み時における左右へのブレを抑制して品位の高いスムーズな引出し扉の開閉動作を簡単な構成で得ることができる。   According to the present invention, in order to facilitate storing and taking out stored foods, even if the amount of the storage container held on the door is increased, it is possible to suppress left and right blurring when the door is pulled out or pushed in. A high-quality smooth opening / closing operation of the drawer door can be obtained with a simple configuration.

以下、本発明の1実施形態につき図面を参照して説明する。図1に全体の縦断面図、図2に冷凍室扉を開扉した状態の側面図を示す冷蔵庫本体(1)は、外箱(2)と内箱(3)との間に発泡断熱材(4)を充填して断熱箱体を形成し、貯蔵室内部を断熱仕切壁(5)によって上部の冷蔵室(6)と下部の冷凍空間(7)とに区画している。   Hereinafter, an embodiment of the present invention will be described with reference to the drawings. The refrigerator main body (1) which shows the whole longitudinal cross-sectional view in FIG. 1, and the side view of the state which opened the freezer compartment door in FIG. 2 is a foam heat insulating material between an outer box (2) and an inner box (3). (4) is filled to form a heat-insulating box, and the interior of the storage compartment is partitioned into an upper refrigerating chamber (6) and a lower refrigerating space (7) by a heat insulating partition wall (5).

前記冷蔵室(6)の前面開口部は観音開き式の左右の扉(8)によって閉塞するとともに、内部の上方部は複数段の載置棚(9)を設けた冷蔵貯蔵室(10)とし、冷蔵貯蔵室(10)の下方には、透明樹脂製の載置棚を兼ねたの天井仕切板(12)で仕切ることでその下部に独立空間を形成し、内部に引き出し式の野菜容器(13)を配置することで野菜室(11)とし、さらに冷蔵室(6)内の最下部には、同様に前記野菜室(11)の底面を形成する底面仕切板(14)を介して室内を0〜−3℃程度に冷却する低温容器を設けた低温室(15)を区画配設している。   The front opening of the refrigerating room (6) is closed by a double door left and right door (8), and the upper part inside is a refrigerating storage room (10) provided with a plurality of mounting shelves (9). Below the refrigerated storage room (10) is partitioned by a ceiling partition plate (12) that also serves as a mounting shelf made of transparent resin, so that an independent space is formed in the lower part, and a drawer-type vegetable container (13 ) Is placed in the vegetable compartment (11), and the bottom part of the refrigerator compartment (6) is similarly placed through the bottom partition plate (14) that forms the bottom of the vegetable compartment (11). A cryogenic chamber (15) provided with a cryogenic container that cools to about 0 to -3 ° C is partitioned.

前記野菜容器(13)は、周壁および立ち上がり高さの低い前壁(13a)とからなる上面を開放した容器であり、その両側壁の外面に前後方向に亙って設けた突条を内箱側のレールに支持することで前後方向に摺動可能として引き出し自在な構成としており、野菜容器(13)を冷蔵室(6)内の所定の位置に収納し設置した場合には、前記天井仕切板(12)によって上面が閉塞され、前記野菜容器(13)の前壁(13a)と天井仕切板(12)の前縁で形成される開口部は蓋体(16)により、野菜容器(13)の前後移動に連動して開閉するとともに、手動にてもその開閉、あるいは常時開状態を保持するようにしている。   The vegetable container (13) is a container having an open upper surface composed of a peripheral wall and a front wall (13a) having a low rising height, and a ridge provided on the outer surface of both side walls in the front-rear direction. When the vegetable container (13) is stored and installed at a predetermined position in the refrigerator compartment (6), the ceiling partition can be pulled out. The upper surface is closed by the plate (12), and the opening formed by the front wall (13a) of the vegetable container (13) and the front edge of the ceiling partition plate (12) is formed by the lid (16). ) In conjunction with the back-and-forth movement, and the manual opening or closing or the normally open state is maintained.

冷蔵室(6)下部の冷凍空間(7)については、前記断熱仕切壁(5)の直下に比較的小容積の冷却貯蔵室、例えば、−18℃や−9℃のソフト冷凍温度帯などの冷凍温度に冷却することができる温度切替室(17)と、同様に比較的小容積の自動製氷装置を備えた製氷室とをその前面開口部に設けた縦仕切板で左右に区分し、それぞれの前面開口部に設けた扉とともに引き出し式で併置している。   For the refrigerating space (7) at the lower part of the refrigerator compartment (6), a relatively small-sized cooling storage room, for example, a soft freezing temperature zone of −18 ° C. or −9 ° C. is provided directly below the heat insulating partition wall (5). A temperature switching chamber (17) that can be cooled to the freezing temperature and an ice making chamber that is also equipped with a relatively small volume automatic ice making device are divided into left and right by a vertical partition plate provided at the front opening, respectively, It is juxtaposed with a drawer with a door provided in the front opening.

併置している前記温度切替室(17)と製氷室の下部には、前面を横仕切板(18)で上下に区画し、前記同様に引き出し扉式として底面からの高さ寸法を350〜500mmと従来に比し大きくした冷凍室(20)を本体の全幅に亙って設けている。   In the lower part of the temperature switching chamber (17) and the ice making chamber that are juxtaposed, the front surface is divided up and down by a horizontal partition plate (18), and the height dimension from the bottom is 350 to 500 mm as a drawer door type as above. The freezer compartment (20), which is larger than before, is provided over the entire width of the main body.

冷凍室(20)の前面開口部を開閉自在に閉塞する断熱体からなる冷凍室扉(21)の庫内側を形成する内板(22)には、図3の斜視図で示すように、内側への固定部(23a)とともに室内奥行き方向に延出してほぼL字状に折曲する支持部(23b)を形成した左右一対の支持枠(23)を固着しており、この支持枠(23)とともに、関連部分の斜視図である図4に示すように、冷凍室(20)の両側壁面に前後方向に亙って配置したスライドレール(30)によって収納容器(25)を保持し、前後に摺動可能な引出し方式としている。   As shown in the perspective view of FIG. 3, the inner plate (22) forming the inner side of the freezer compartment door (21) made of a heat insulator that can freely open and close the front opening of the freezer compartment (20) A pair of left and right support frames (23) that form a support portion (23b) that extends in the depth direction of the room and bends substantially in an L shape together with the fixing portion (23a) are fixed to the support frame (23 ) And the storage container (25) is held by slide rails (30) arranged in the front-rear direction on both side walls of the freezer compartment (20) as shown in FIG. The drawer system is slidable.

収納容器(25)の後部には、冷気を生成し、冷凍空間の各貯蔵室に供給する冷凍用冷却器(28)やファン(29)を配置しており、冷凍室(20)の前面開口部に配置した冷凍室扉(21)の内面側周縁部には、軟質合成樹脂で形成されたガスケット(36)を挿着し、閉扉の際には冷凍室(20)内を密閉するように構成している。   A freezing cooler (28) and a fan (29) are arranged at the rear of the storage container (25) to generate cold air and supply it to each storage room in the freezing space. The front opening of the freezing room (20) Insert a gasket (36) made of soft synthetic resin into the inner peripheral edge of the freezer compartment door (21) placed in the section, and seal the inside of the freezer compartment (20) when closing the door It is composed.

前記図4、および前記収納容器(25)の左側のレール支持部分の正面からの断面図である図5に示すように、前記スライドレール(30)は、冷凍室(20)を形成する内箱(3)の両側内面に奥行き方向に亙るように固着された鋼板からなる板状体の上下辺に内方向に延出する鍔部(31a)を設けた固定レール(31)と、収納容器(25)の一部を支持する前記支持枠(23)の室内奥行き側の支持部(23b)の上面に形成した鍔部(23c)がその上面に係合する支え部材(32)と、この支え部材(32)を一体に固定し、前記固定レール(31)の鍔部(31a)間に位置するようにその上下辺から外方向に鍔部(33a)を延出させた可動レール(33)と、これら内外のレール(31)(33)の間に設けられて前記固定レール(31)の鍔部(31a)と可動レール(33)の鍔部(33a)との間に位置する鍔部(34a)を内方向に設けた中間レール(34)とから構成されている。   As shown in FIG. 4 and FIG. 5, which is a cross-sectional view from the front of the left rail support portion of the storage container (25), the slide rail (30) is an inner box that forms a freezer compartment (20). (3) a fixed rail (31) provided with flanges (31a) extending inwardly on the upper and lower sides of a plate-like body made of a steel plate fixed to the inner surface on both sides in the depth direction; and a storage container ( 25) a support member (32) that engages the upper surface of the flange (23c) formed on the upper surface of the support portion (23b) on the indoor depth side of the support frame (23) that supports a part of the support frame (23); A movable rail (33) in which a member (32) is fixed integrally and a flange (33a) is extended outward from the upper and lower sides so as to be positioned between the flanges (31a) of the fixed rail (31) And the flange (31a) of the fixed rail (31) and the movable rail (33) provided between the inner and outer rails (31) (33). It is comprised from the intermediate rail (34) which provided the collar part (34a) located between a collar part (33a) inward.

前記中間レール(34)は、その鍔部(34a)と、前記固定レール(31)と可動レール(33)の各鍔部(31a)(33a)との間に嵌挿したボールベアリング(35)によりそれぞれと係合し、スライドレール(30)として実質的に一体化されるとともに前後に摺動自在に保持されてダブルレールを形成しており、固定レール(31)内を摺動する中間レール(34)およびこの中間レール(34)内を摺動することによって可動レール(33)は2段階で引き出されることになる。   The intermediate rail (34) includes a flange (34a) and a ball bearing (35) fitted between the fixed rail (31) and the flanges (31a) (33a) of the movable rail (33). The intermediate rail that engages with each other and is substantially integrated as a slide rail (30) and is slidably held back and forth to form a double rail, and slides in the fixed rail (31) The movable rail (33) is pulled out in two stages by sliding in (34) and the intermediate rail (34).

なお、前記支え部材(32)は、あらかじめ可動レール(33)の室内側に沿わせるとともにリベットなどで一体に嵌め固定しており、断面はほぼL字状をなしてその上辺には前記支持枠(23)の上辺鍔部(23c)と係合する鍔部(32a)を形成している。また、前記支え部材(32)と可動レール(33)は一体に形成するようにしてもよい。   The support member (32) is preliminarily fitted along the indoor side of the movable rail (33) and is integrally fitted and fixed with a rivet or the like, and the cross section is substantially L-shaped, and the support frame is formed on the upper side thereof. (23) A hook part (32a) that engages with the upper side hook part (23c) is formed. Further, the support member (32) and the movable rail (33) may be formed integrally.

それゆえ、スライドレール(30)を冷凍室(20)内から引き出した状態において、可動レール(33)に固着された支え部材(32)の鍔部(32a)上に保持された収納容器(25)は、従来のシングルレール方式に比し、各レール(33)(34)(35)間の保持機構によってその後端部が冷凍室(20)の前面開口部より前方までフルオープン状態で大きく引き出される。   Therefore, in a state where the slide rail (30) is pulled out from the freezer compartment (20), the storage container (25 held on the flange (32a) of the support member (32) fixed to the movable rail (33). Compared to the conventional single-rail system, the rear end of the rail (33), (34) and (35) is fully pulled out from the front opening of the freezer compartment (20) to the front by the holding mechanism. It is.

収納容器(25)は、合成樹脂の射出成型品であって上面を開口した底の深い箱状をなしており、その開口した上面の周縁にはフランジ部を形成し、このフランジ部を利用して前記開口をほとんど覆うとともに、前縁の一部を切り欠いて高さのある製氷用牛乳パック容器などが収納できる後方への凹陥部を有する比較的底の浅い皿状の中段容器(26)を載置している。   The storage container (25) is an injection-molded product made of synthetic resin and has a deep box shape with an open top surface. A flange is formed on the periphery of the open top surface. A relatively shallow shallow dish-shaped middle container (26) having a recessed part to the rear that covers most of the opening and that can accommodate a tall ice-making milk container with a part of the front edge cut away. It is placed.

そして、冷凍室扉(21)を引き出した際には、収納容器(25)とともに中段容器(26)が、レール部材によってその後端が冷凍室(20)の前面開口部より前方に出るまでフルオープン状態で大きく引き出されるものであり、中段容器(26)は収納容器(25)のフランジ部上を前後方向に摺動可能として収納容器(25)の上面開口を開閉し、また中段容器(26)自体の引き出し収納ができるように設けている。 前記収納容器(25)および中段容器(26)の上方には、これら容器(25)(26)および冷凍室扉(21)の開閉とは関連なく、独立して引き出し、また庫内に収納される上段容器(27)を設置している。   When the freezer compartment door (21) is pulled out, the middle container (26) together with the storage container (25) is fully opened by the rail member until its rear end comes out forward from the front opening of the freezer compartment (20). The middle container (26) is slidable in the front-rear direction on the flange of the storage container (25), opens and closes the top opening of the storage container (25), and the middle container (26) It is provided so that it can be pulled out and stored. Above the storage container (25) and middle container (26), these containers (25) (26) and freezer compartment door (21) are independently pulled out and stored in the storage, regardless of whether the freezer compartment door (21) is open or closed. The upper container (27) is installed.

したがって、冷凍室(20)には、上下3段の引出し式の容器(25)(26)(27)が配置されているものであり、前記上段容器(27)は、中段容器(26)の上方に位置しているが、その保持は、上段容器(27)の上面開口の両側縁に形成したフランジ部を冷凍室(20)の側壁に内方へ突出して設けた支持レールに直接支承し、前後に摺動可能に支持する構成であることから、冷凍室扉(21)と中段容器(26)および下段の収納容器(25)を支えているレール部材に荷重負担は掛からないとともに、冷凍室扉(21)の開扉には連動しない構成であり、上段容器(27)を引き出す場合は、冷凍室扉(21)を引き出した後に、冷凍室扉(21)の裏面上部に対向して位置する上段容器(27)の前壁の一部に形成した把手を把持して独自に引き出し、また室内に押し込むことになる。   Accordingly, the freezer compartment (20) is provided with three upper and lower drawer-type containers (25), (26), and (27), and the upper container (27) is the middle container (26). Although it is located above, the holding is supported directly on the support rail provided on the side wall of the freezer compartment (20) with flanges formed on both side edges of the upper opening of the upper container (27). Since it is configured to be slidably supported back and forth, the load is not applied to the rail member supporting the freezer compartment door (21), the middle container (26), and the lower container (25). It is not linked to the opening of the chamber door (21). When pulling out the upper container (27), after pulling out the freezer door (21), face the upper back of the freezer door (21). Hold the handle formed on a part of the front wall of the upper container (27), pull it out, and push it into the room. It becomes Mukoto.

そして、前記各容器毎の収納深さの差と冷凍室扉(21)との連動の有り無しにより、各容器内へ収納する食品を区分するものであり、例えば、冷凍室扉(21)に連動して開閉される最下部の収納容器(25)内には、比較的大形状で多用する冷凍食品を収納し、浅底の中段容器(26)には比較的小形で頻繁に使用する食品を収納するようにすれば、冷凍室扉(21)の開扉に連動して収納容器(25)および中段容器(26)が引き出されるので、使い勝手よく食品を取り出し、また収納することができる。   And the food stored in each container is classified according to the difference in the storage depth for each container and whether or not the freezer compartment door (21) is linked, for example, to the freezer compartment door (21). The lowermost storage container (25), which is opened and closed in conjunction, stores frozen foods that are relatively large in shape and frequently used, and the shallow middle container (26) is relatively small and frequently used. If the container is stored, the storage container (25) and the middle container (26) are pulled out in conjunction with the opening of the freezer compartment door (21), so that the food can be taken out and stored conveniently.

上段容器(27)には、大形状で比較的長期に亙るストックを目的にした冷凍食品を収納するようにすれば、容器の収納深さが深いことから余裕をもって食品を収納できる。また冷凍室扉(21)の開閉に連動せずに室内での収納状態を保持するので、必要なときに任意に引き出せばよく、冷凍室扉(21)の開扉の都度引き出されることによる外部空気温度の影響を抑制でき、ストック食品を長期間に亙って好適に冷凍保存することができる。   In the upper container (27), if frozen food intended for stock having a large shape and relatively long-term storage is stored, the container can be stored with a margin because the container is deep. In addition, since it is stored in the room without interlocking with the opening and closing of the freezer compartment door (21), it can be pulled out arbitrarily when necessary, and it can be externally pulled out whenever the freezer compartment door (21) is opened. The influence of the air temperature can be suppressed, and the stock food can be suitably stored frozen for a long period of time.

すなわち、引き出し式の各容器を上記のように配置し構成することにより、それぞれ食品の形状や大きさ、使用頻度や用途、扉開閉に連動するか否かによる使い勝手に合わせた効果的な使い方ができる。   In other words, by arranging and configuring each of the drawer-type containers as described above, it is possible to effectively use the food according to the shape and size of the food, the usage frequency and usage, and whether or not it is linked to the door opening / closing. it can.

しかして、引出し式冷凍室扉(21)の内板(22)の下部両側には、前記図3および要部の拡大図である図6から明らかなように、対向する収納容器(25)の下部前面側に突出するリブ片(37)を一体に形成している。このリブ片(37)は扉裏面の左右の支持枠(23)およびスライドレール(30)間に収納容器(25)を設置した場合には、その先端が収納容器(25)下部の幅方向前面に当接または近接するように設けられている。   As shown in FIG. 3 and FIG. 6 which is an enlarged view of the main part, the opposing storage container (25) is provided on both sides of the lower part of the inner plate (22) of the drawer-type freezer compartment door (21). A rib piece (37) protruding to the lower front side is integrally formed. When the storage container (25) is installed between the left and right support frames (23) and the slide rail (30) on the back of the door, this rib piece (37) is the front in the width direction at the bottom of the storage container (25). It is provided so that it may contact | abut or adjoin to.

通常、前記内板(22)と収納容器(25)前面との間には、組立上の寸法ばらつきを吸収して引き出し状態における支持枠(23)およびスライドレール(30)からの収納容器(25)の取り外しや取り付けをスムーズにおこなうために設計的に数ミリメートルの間隙tを設けている。一方、収納容器(25)を保持した支持枠(23)およびスライドレール(30)と引出し式の冷凍室扉(21)との固着は、冷凍室扉(21)のほぼ上下高さ方向の中央部の両側の2点のみとなる。   Usually, between the inner plate (22) and the front surface of the storage container (25), the storage container (25 from the support frame (23) and the slide rail (30) in the pulled-out state is accommodated by absorbing dimensional variations in assembly. ) In order to smoothly remove and attach), a gap t of several millimeters is provided by design. On the other hand, the support frame (23) holding the storage container (25), the slide rail (30), and the drawer-type freezer compartment door (21) are firmly attached to the center of the freezer compartment door (21) in the vertical direction. There are only two points on both sides of the part.

このことから、前記間隙tが存在すると、ガスケット(36)が本体側に吸着している閉扉時を除き、冷凍室扉(21)が本体から離間する開扉時においては、前記支持枠(23)との固着点を支点として、扉(21)がその上下部で前後に倒れやすくなる。これは、前述のように高さ寸法の大きい冷凍室用の引出し扉(21)については特に顕著に発生するものであり、また、左右方向に対しても剛性は弱くひねれやすくなるものである。   From this, when the gap t exists, the support frame (23) is opened when the freezer compartment door (21) is separated from the main body except when the gasket (36) is adsorbed to the main body side. ), The door (21) tends to fall back and forth at the top and bottom. This is particularly noticeable with respect to the drawer door (21) for a freezer compartment having a large height as described above, and the rigidity is weak and easily twisted in the left-right direction.

したがって、例えば、閉扉時に冷凍室扉(21)のハンドルの中央部から左右にずれた位置を把持して庫内側へ押し込んだ場合には、ひねれ現象によりスライドレール(30)の摺動がぎくしゃくし、きわめて閉扉し難い状況が発生することになる。   Therefore, for example, when the handle is pushed to the inner side of the freezer compartment door (21) when it is closed, the slide rail (30) slides due to the twisting phenomenon. This will cause a situation that is extremely difficult to close.

このひねれ現象に対して、上記構成によれば、収納容器(25)の前面下部に当接あるいは近接状態にある前記内板(22)のリブ片(37)は、貯蔵品により重量体となっている収納容器(25)の重力を受けることから、わずかに左右、あるいは上下にブレた場合でも内板(22)に当接してその両側を押圧することになり、ブレを発生させる力に対する踏ん張り作用を発揮するため、ブレの発生を極端に抑制することができる。   With respect to this twist phenomenon, according to the above configuration, the rib piece (37) of the inner plate (22) that is in contact with or close to the lower front surface of the storage container (25) becomes a heavy body due to the stored product. Because of the gravitational force of the storage container (25), even if it shakes slightly to the left or right or up and down, it will abut against the inner plate (22) and press on both sides, and it will be a strut to the force that generates the shake Since the effect is exhibited, the occurrence of blurring can be extremely suppressed.

また、前記冷凍室扉(21)の前後への倒れについても、前記支持枠(23)による支点とともに作用点であるリブ片(37)と収納容器(25)の前面とが当接することによって固定されるため、扉としての前後方への傾き現象をも抑止できるものである。   Further, the freezing compartment door (21) is fixed by the front and rear of the container (25) coming into contact with the rib piece (37), which is the action point, together with the fulcrum by the support frame (23). Therefore, the front and rear tilt phenomenon as a door can be suppressed.

前記内板(22)の下方に設けるのは、薄肉のリブ片(37)で充分であり、上記構成であれば、内板(22)と収納容器(25)との間隙に冷気を流通させる形態の場合にも冷気の流れを阻害しないものであるが、これに限らず、内板(22)の下方全体を収納容器(25)側に膨出させても同様の剛性強度が得られるものである。   A thin rib piece (37) is sufficient to be provided below the inner plate (22). With the above configuration, cold air is circulated through the gap between the inner plate (22) and the storage container (25). Even in the case of the form, it does not inhibit the flow of cold air, but is not limited to this, and the same rigidity and strength can be obtained even if the entire lower part of the inner plate (22) is bulged toward the storage container (25) side It is.

なお、前記リブ片(37)などを内板(22)側ではなく、収納容器(25)側の下端両側に設けて、それぞれを内板(22)に当接あるいは近接させるようにしても扉のひねれや傾き現象を抑制することができるが、その場合は、着脱する機会の多い収納容器(25)の下方に凸起部が形成されることから、着脱に支障がでたり、着脱時の当たりやこすれが発生し易くなるものであり、実施には、収納容器(25)の着脱動作にほとんど影響がない内板(22)側の下部に形成する方が望ましい。   In addition, the rib piece (37) or the like is provided not on the inner plate (22) side, but on both sides of the lower end of the storage container (25) side so that each of the rib pieces (37) is in contact with or close to the inner plate (22). Twist and tilt phenomenon can be suppressed, but in this case, a protruding part is formed below the storage container (25) where there are many opportunities to attach and detach. It is easy to generate hitting and rubbing, and it is desirable to form it at the lower part on the inner plate (22) side that hardly affects the attaching / detaching operation of the storage container (25).

また、扉の内板(22)の下部と対向する収納容器(25)の前面下部とのいずれか一方に対向側へ突出するリブ片(37)を形成し、このリブ片(37)の先端を対向側の収納容器(25)あるいは内板(22)に当接あるいは近接させる場合には、内板(22)と収納容器(25)の前面との対向部に、あらかじめ2〜3ミリメートルの間隙を設けておき、冷凍室扉(21)の支持枠(23)およびスライドレール(30)間に収納容器(25)を保持させることで、その重力による変位で収納容器(25)がリブ片(37)に当接あるいは近接させるようにしてもよい。   In addition, a rib piece (37) protruding to the opposite side is formed on either the lower part of the inner plate (22) of the door or the lower part of the front face of the storage container (25), and the tip of the rib piece (37) In contact with or in close proximity to the storage container (25) or the inner plate (22) on the opposite side, a portion of 2 to 3 millimeters in advance is placed on the opposing portion between the inner plate (22) and the front surface of the storage container (25). By providing a gap and holding the storage container (25) between the support frame (23) of the freezer compartment door (21) and the slide rail (30), the storage container (25) is ribbed by the displacement due to its gravity. You may make it contact | abut or adjoin to (37).

この場合は、前記間隙が存在しても収納容器(25)の組み込み時や貯蔵品の収納時にはその重力によりリブ片(37)が収納容器(25)に当接あるいは近接状態になるため、開閉扉時における冷凍室扉(21)のひねれや傾きを抑制できる効果を有するのみでなく、前記内板(22)と収納容器(25)前面との間の組立上の寸法ばらつきを吸収することができ、組み込み性を良好に保持することができる。   In this case, even when the gap exists, the rib piece (37) is brought into contact with or close to the storage container (25) due to its gravity when the storage container (25) is assembled or stored goods are stored. Not only has the effect of suppressing twisting and tilting of the freezer compartment door (21) at the time of the door, but also absorbs dimensional variations in assembly between the inner plate (22) and the front surface of the storage container (25). And can maintain good embeddability.

なお、上記実施例においては、レール部材としてスライドレール(30)を例として説明したが、これに限らず、従来のいわゆるシングルタイプのレールにも適用できることはいうまでもなく、また、対象とする引出し扉についても、冷凍室扉(21)に限らず他の引き出し式扉でもよいものである。   In addition, in the said Example, although the slide rail (30) was demonstrated as an example as a rail member, it is needless to say that it is applicable not only to this but the conventional so-called single type rail. The drawer door is not limited to the freezer compartment door (21), and other drawer doors may be used.
