Abstract

<P>PROBLEM TO BE SOLVED: To provide a directly cooled refrigerator with a function of draining defrosting water in a refrigerating chamber to the outside of the refrigerating chamber, wherein a temperature on a door shelf of the uppermost part is reduced. <P>SOLUTION: In the refrigerating chamber 19, an aluminum plate 20 with its upper part having an inclined face 21 inclined to the inside is mounted on the back face of an inner box. The inclined face 21 is located on the upper side of an inside shelf of the uppermost part on a vertical line and a food mounting face of the inside shelf of the uppermost part is located on the upper side beyond the upper end of the door shelf of the uppermost part. Thus, an air path for cooled air is formed ranging from the aluminum plate 20 to the door shelf of the uppermost part, reducing a temperature on the door shelf of the uppermost part. The defrosting water on the inclined face 21 of the aluminum plate 20 flows along the inclined face 21 and so it is accurately guided to a drain part 16, maintaining the draining function of the refrigerator. <P>COPYRIGHT: (C)2006,JPO&NCIPI

Description

本発明は、冷蔵庫の冷却仕様に関するものである。 The present invention relates to a refrigerator cooling specification.

従来より小型の冷蔵庫においては、直接冷却方式が一般的に採用されている（例えば特許文献１参照）。 A direct cooling method is generally employed in refrigerators that are smaller than conventional ones (see, for example, Patent Document 1).

図１０は従来の冷蔵庫の断面図、図１１は従来の冷蔵室の正面図、図１２は従来の冷蔵庫の内箱の背面斜視図である。 10 is a sectional view of a conventional refrigerator, FIG. 11 is a front view of a conventional refrigerator, and FIG. 12 is a rear perspective view of an inner box of a conventional refrigerator.

１は冷蔵庫本体で外箱２と内箱３で囲まれた空間に断熱材４が充填され、上室が冷蔵室５、下室が冷凍室６である。冷蔵室５には食品を載せる第１の庫内棚７、第２の庫内棚８が上下にまた、冷蔵室ドア９には第１のドア棚１０、第２のドア棚１１が備えられていて、冷却器１２は、冷蔵室５を冷却するための蛇行形状を有する冷蔵室冷却パイプ１３と冷凍室６を冷却するための同じく蛇行形状を有する冷凍室冷却パイプ１４から成り、冷蔵室冷却パイプ１３は内箱３の背面の断熱材４側に、冷凍室冷却パイプ１４は内箱３の複数面の断熱材４側に取付けられ、冷却器１２からの熱伝導により冷却された内箱３が冷蔵室５及び冷凍室６を冷却している。１５は冷却器１２に冷媒を供給するための圧縮機であり、圧縮機１５の運転と停止を繰り返すことで、冷蔵室５と冷凍室６は所定の温度に保たれている。また、圧縮機１５の停止中毎には、冷蔵室５外からの吸熱により内箱３の温度が昇温するが、この時内箱３に付着した氷が融解し、融解した除霜水が内箱３を伝って下方に流れ落ちる。この除霜水を冷蔵室５外に排出するために、内箱３の背面下部に除霜水を受けるための第１のドレン部１６を備え、かつ第１のドレン部１６の一部には冷蔵室５外と連通している第１の排水管部１７を設けている。この霜取り方式は冷蔵室の除霜水を拭き取る手間も無いので使い勝手が良く、また安価でもあるため、小型機種に一般的に用いられている。
特開平７−１２０１０８号公報 Reference numeral 1 denotes a refrigerator body, in which a space surrounded by the outer box 2 and the inner box 3 is filled with a heat insulating material 4, the upper chamber is a refrigerator compartment 5, and the lower chamber is a freezer compartment 6. The refrigerator compartment 5 is provided with a first cabinet shelf 7 and a second cabinet shelf 8 on which food is placed, and the refrigerator compartment door 9 is provided with a first door shelf 10 and a second door shelf 11. The cooler 12 includes a refrigerator compartment cooling pipe 13 having a meandering shape for cooling the refrigerator compartment 5 and a freezer compartment cooling pipe 14 having a meandering shape for cooling the freezer compartment 6. The pipe 13 is attached to the heat insulating material 4 side on the back surface of the inner box 3, and the freezer compartment cooling pipe 14 is attached to the heat insulating material 4 side of a plurality of surfaces of the inner box 3, and is cooled by heat conduction from the cooler 12. Cools the refrigerator compartment 5 and the freezer compartment 6. Reference numeral 15 denotes a compressor for supplying a refrigerant to the cooler 12, and the refrigerator 15 and the freezer compartment 6 are kept at a predetermined temperature by repeatedly operating and stopping the compressor 15. Further, every time the compressor 15 is stopped, the temperature of the inner box 3 rises due to heat absorption from the outside of the refrigerator compartment 5. At this time, the ice adhering to the inner box 3 is melted, and the defrosted water is melted. It flows down along the inner box 3. In order to discharge this defrost water to the outside of the refrigerator compartment 5, a first drain portion 16 for receiving the defrost water is provided at the lower back of the inner box 3, and a part of the first drain portion 16 is provided. A first drain pipe portion 17 communicating with the outside of the refrigerator compartment 5 is provided. This defrosting method is easy to use because it does not require the effort to wipe off the defrosted water in the refrigerator compartment, and is also inexpensive, so it is generally used for small models.
JP-A-7-120108

しかしながら、上記従来例に記載されている冷蔵庫の冷蔵室においては、除霜水をドレン部で受け冷蔵庫外に排出するために、冷蔵室冷却パイプが内箱背面にしかなく、また、内箱背面の除霜水が庫内棚に流れないように、確実に除霜水をドレン部に導くために、庫内棚は内箱背面とは隙間を設けて備えられている。この結果、冷やされ比重が大きくなった空気の一部はこの隙間が風路となり、冷蔵室の下方へと移動する。このため、最上部に位置する第１のドア棚まで冷気が届き難く、第１のドア棚の温度が高いという問題があった。 However, in the refrigerator compartment of the refrigerator described in the above-mentioned conventional example, in order to receive defrost water at the drain part and to discharge outside the refrigerator, the refrigerator compartment cooling pipe is only on the inner box rear side, and the inner box rear side In order to ensure that the defrosted water does not flow to the inner shelf, the inner shelf is provided with a gap from the inner box rear surface in order to reliably guide the defrosted water to the drain portion. As a result, a part of the air that has been cooled and has a high specific gravity moves to the lower side of the refrigerating chamber because this gap serves as an air passage. For this reason, there is a problem that it is difficult for cold air to reach the first door shelf located at the top, and the temperature of the first door shelf is high.

本発明は上記課題に鑑み、直冷式冷蔵室においても第１のドア棚の温度を低減する冷蔵庫を提供するものである。 This invention provides the refrigerator which reduces the temperature of a 1st door shelf also in a direct-cooling-type refrigerator compartment in view of the said subject.

上記従来の課題を解決するために、冷蔵室冷却パイプが内箱の背面の断熱材側に取付けられた直冷式冷蔵庫の冷蔵室内に、上部が庫内側に傾斜した傾斜面を有するアルミプレートを内箱背面に取り付け、前記傾斜面が最上部の庫内棚の鉛直線上の上方に位置し、最上部のドア棚の上端よりも最上部の庫内棚の食品塔載面が上部に位置することを特徴としたものである。 In order to solve the above-described conventional problems, an aluminum plate having an inclined surface whose upper part is inclined toward the inside of the refrigerator is provided in the refrigerator compartment of a direct-cooling refrigerator in which the refrigerator compartment cooling pipe is attached to the heat insulating material side on the back of the inner box. Attached to the back of the inner box, the inclined surface is located above the vertical line of the uppermost shelf, and the food tower mounting surface of the uppermost shelf is located above the upper end of the uppermost door shelf. It is characterized by that.

これによって、冷蔵室冷却パイプによって冷却された内箱が、アルミプレートを冷却し、アルミプレートにより冷却された空気は自然対流により冷蔵室内を循環することで冷蔵室内が冷却される。冷却された空気は比重が大きくなり冷蔵室の下方に移動するが、アルミプレートの傾斜面により冷却された空気は傾斜面の下部に位置している最上部の庫内棚の食品搭載面で受けられる。食品搭載面で受けられた空気は食品搭載面上を前後左右へと拡散しさらに冷蔵室の下方へと移動するが、前部に移動した空気は食品搭載面より下部に最上部のドア棚が位置しているため、最上部のドア棚に移動する。つまり、アルミプレートから最上部のドア棚まで、冷却された空気の風路が形成されているため、最上部のドア棚の温度を低減することができる。アルミプレートの傾斜面についた除霜水は傾斜面に沿って流れるためドレン部に確実に導かれるため、冷蔵庫の排水性機能は維持される。 As a result, the inner box cooled by the refrigerating room cooling pipe cools the aluminum plate, and the air cooled by the aluminum plate circulates in the refrigerating room by natural convection, thereby cooling the refrigerating room. The cooled air has a higher specific gravity and moves downward in the refrigerator compartment, but the air cooled by the inclined surface of the aluminum plate is received by the food mounting surface of the uppermost shelf in the lower part of the inclined surface. It is done. The air received on the food loading surface diffuses forward, backward, left and right on the food loading surface, and further moves downward in the refrigerator compartment, but the air moved to the front has an uppermost door shelf below the food loading surface. Because it is located, it moves to the top door shelf. That is, since the air path of the cooled air is formed from the aluminum plate to the uppermost door shelf, the temperature of the uppermost door shelf can be reduced. Since the defrost water on the inclined surface of the aluminum plate flows along the inclined surface, it is reliably guided to the drain portion, so that the drainage function of the refrigerator is maintained.

また、本発明の冷蔵庫は、冷蔵室冷却パイプが冷却プレートを介して内箱の背面の断熱材側に取付けられた直冷式冷蔵庫で、内箱背面が、庫内側に傾斜した傾斜面を上部に、傾斜面より下部に垂直面を持ち、前記冷却プレートも、前記内箱背面の傾斜面と垂直面に密着配置するよう、傾斜面を上部に、傾斜面より下部に垂直面を持たせ、内箱の傾斜面が最上部の庫内棚の鉛直線上の上方に位置し、最上部のドア棚の上端よりも最上部の庫内棚の食品塔載面が上部に位置することを特徴としたものである。 The refrigerator of the present invention is a direct cooling refrigerator in which the refrigerator compartment cooling pipe is attached to the heat insulating material side of the back of the inner box through the cooling plate, and the inner box back has an inclined surface that is inclined to the inside of the warehouse. In addition, it has a vertical surface below the inclined surface, and the cooling plate also has a vertical surface on the upper side and a lower surface than the inclined surface so that the cooling plate is arranged in close contact with the inclined surface and the vertical surface on the back of the inner box, The inclined surface of the inner box is located above the vertical line of the uppermost shelf, and the food tower mounting surface of the uppermost shelf is located above the upper end of the uppermost door shelf. It is a thing.

これによって、冷蔵室冷却パイプによって冷却された冷却プレートが内箱を冷却し、内箱により冷却された空気は自然対流により冷蔵室内を循環することで冷蔵室内が冷却される。冷却された空気は比重が大きくなり冷蔵室の下方に移動するが、内箱の傾斜面により冷却された空気は傾斜面の下部に位置している最上部の庫内棚の食品搭載面で受けられる。食品搭載面で受けられた空気は食品搭載面上を前後左右へと拡散しさらに冷蔵室の下方へと移動するが、前部に移動した空気は食品搭載面より下部に最上部のドア棚が位置しているため、最上部のドア棚に移動する。つまり、内箱の傾斜面から最上部のドア棚まで、冷却された空気の風路が形成されているため、最上部のドア棚の温度を低減することができる。内箱の傾斜面についた除霜水は傾斜面に沿って流れるためドレン部に確実に導かれるため、冷蔵庫の排水性機能は維持される。 Thereby, the cooling plate cooled by the refrigerator compartment cooling pipe cools the inner box, and the air cooled by the inner box is circulated in the refrigerator compartment by natural convection to cool the refrigerator compartment. The cooled air increases in specific gravity and moves below the refrigerator compartment, but the air cooled by the inclined surface of the inner box is received by the food loading surface of the uppermost shelf in the lower part of the inclined surface. It is done. The air received on the food loading surface diffuses forward, backward, left and right on the food loading surface, and further moves downward in the refrigerator compartment, but the air moved to the front has an uppermost door shelf below the food loading surface. Because it is located, it moves to the top door shelf. That is, since the air path of the cooled air is formed from the inclined surface of the inner box to the uppermost door shelf, the temperature of the uppermost door shelf can be reduced. Since the defrost water on the inclined surface of the inner box flows along the inclined surface, it is reliably guided to the drain portion, so that the drainage function of the refrigerator is maintained.

また、本発明の冷蔵庫は、最上部の庫内棚が食品を塔載するための食品塔載面と内箱の背面に付着した除霜水を受ける棚ドレン部からなり、食品塔載面は前部に、棚ドレン部は後部に位置し、棚ドレン部は水をドレン部に導くための棚排水管部を有し、最上部のドア棚の上端よりも前記食品塔載面が上部に位置することを特徴としたものである。 In addition, the refrigerator of the present invention comprises a food tower mounting surface on which the uppermost shelf in the cabinet is mounted with food and a shelf drain portion that receives defrost water attached to the back of the inner box, At the front part, the shelf drain part is located at the rear part, the shelf drain part has a shelf drain pipe part for guiding water to the drain part, and the food tower mounting surface is above the upper end of the uppermost door shelf. It is characterized by being located.

これによって、最上部の庫内棚の食品搭載面へ除霜水が流れこまないので、最上部の庫内棚は内箱背面と接触配置が可能となり、最上部の庫内棚と内箱背面の隙間はほぼ無くすことができ、冷却され比重が大きくなり冷蔵室の下方へと移動する空気は最上部の棚で受けることとなる。最上部の棚で受けられた空気は最上部の棚上を前後左右へと拡散しさらに冷蔵室の下方へと移動するが、前部に移動した空気は食品搭載面より下部に最上部のドア棚が位置しているため、最上部のドア棚に移動する。つまり、内箱背面から最上部のドア棚まで、冷却された空気の風路が形成されているため、最上部のドア棚の温度を低減することができる。 As a result, defrost water does not flow to the food loading surface of the uppermost shelf, so the uppermost shelf can be placed in contact with the inner box back, and the uppermost shelf and inner box rear The gap is almost eliminated, and the air that is cooled and increases in specific gravity and moves downward in the refrigerator compartment is received by the uppermost shelf. The air received on the top shelf diffuses from front to back and left and right on the top shelf and then moves to the lower side of the refrigeration room. Since the shelf is located, it moves to the top door shelf. That is, since the air path of the cooled air is formed from the back of the inner box to the uppermost door shelf, the temperature of the uppermost door shelf can be reduced.

また、本発明の冷蔵庫は、最上部の庫内棚の食品搭載面よりも高い位置の内箱背面に、上部ドレン部と上部ドレン部の一部が冷蔵室外と連通した上部排水管部が備えられ、最上部のドア棚の上端よりも前記食品塔載面が上部に位置することを特徴とすることを特徴としたものである。 Further, the refrigerator of the present invention is provided with an upper drain pipe portion in which the upper drain portion and a part of the upper drain portion communicate with the outside of the refrigerator compartment on the back of the inner box at a position higher than the food mounting surface of the uppermost shelf. The food tower mounting surface is located above the upper end of the uppermost door shelf.

これによって、最上部の庫内棚の食品搭載面へ除霜水が流れこまないので、最上部の庫内棚は内箱背面と接触配置が可能となり、最上部の庫内棚と内箱背面の隙間はほぼ無くすことができ、冷却され比重が大きくなり冷蔵室の下方へと移動する空気は最上部の棚の食品搭載面で受けることとなる。食品搭載面で受けられた空気は食品搭載面上を前後左右へと拡散しさらに冷蔵室の下方へと移動するが、前部に移動した空気は食品搭載面より下部に最上部のドア棚が位置しているため、最上部のドア棚に移動する。つまり、内箱背面から最上部のドア棚まで、冷却された空気の風路が形成されているため、最上部のドア棚の温度を低減することができる。 As a result, defrost water does not flow to the food loading surface of the uppermost shelf, so the uppermost shelf can be placed in contact with the inner box back, and the uppermost shelf and inner box rear The air gap that is cooled and increases in specific gravity and moves downward in the refrigerator compartment is received by the food loading surface of the uppermost shelf. The air received on the food loading surface diffuses forward, backward, left and right on the food loading surface, and further moves downward in the refrigerator compartment, but the air moved to the front has an uppermost door shelf below the food loading surface. Because it is located, it moves to the top door shelf. That is, since the air path of the cooled air is formed from the back of the inner box to the uppermost door shelf, the temperature of the uppermost door shelf can be reduced.

本発明の冷蔵庫は、冷蔵室冷却パイプが内箱の背面の断熱材側に取付けられた直冷式冷蔵庫の冷蔵室内に、上部が庫内側に傾斜した傾斜面を有するアルミプレートを内箱背面に取り付け、前記傾斜面が最上部の庫内棚の鉛直線上の上方に位置させ、最上部のドア棚の上端よりも最上部の庫内棚の食品塔載面を上部に位置させたことで、冷蔵室冷却パイプによって冷却された内箱が、アルミプレートを冷却し、アルミプレートにより冷却された空気は自然対流により冷蔵室内を循環することで冷蔵室内が冷却される。冷却された空気は比重が大きくなり冷蔵室の下方に移動するが、アルミプレートの傾斜面により冷却された空気は傾斜面の下部に位置している最上部の庫内棚の食品搭載面で受けられる。食品搭載面で受けられた空気は食品搭載面上を前後左右へと拡散しさらに冷蔵室の下方へと移動するが、前部に移動した空気は食品搭載面より下部に最上部のドア棚が位置しているため、最上部のドア棚に移動する。つまり、アルミプレートから最上部のドア棚まで、冷却された空気の風路が形成されているため、最上部のドア棚の温度を低減することができる。アルミプレートの傾斜面についた除霜水は傾斜面に沿って流れるためドレン部に確実に導かれるため、冷蔵庫の排水性機能は維持される。 The refrigerator of the present invention has a refrigerator compartment cooling pipe attached to the heat insulating material side of the back of the inner box in the refrigerator compartment of the direct-cooled refrigerator, and an aluminum plate having an inclined surface whose upper part is inclined toward the inner side of the inner box. Mounting, the inclined surface is positioned above the vertical line of the uppermost shelf, and the food tower mounting surface of the uppermost shelf is positioned above the upper end of the uppermost door shelf, The inner box cooled by the refrigerator compartment cooling pipe cools the aluminum plate, and the air cooled by the aluminum plate circulates in the refrigerator compartment by natural convection, thereby cooling the refrigerator compartment. The cooled air has a higher specific gravity and moves downward in the refrigerator compartment, but the air cooled by the inclined surface of the aluminum plate is received by the food mounting surface of the uppermost shelf in the lower part of the inclined surface. It is done. The air received on the food loading surface diffuses forward, backward, left and right on the food loading surface, and further moves downward in the refrigerator compartment, but the air moved to the front has an uppermost door shelf below the food loading surface.

That is, since the air path of the cooled air is formed from the aluminum plate to the uppermost door shelf, the temperature of the uppermost door shelf can be reduced. Since the defrost water on the inclined surface of the aluminum plate flows along the inclined surface, it is reliably guided to the drain portion, so that the drainage function of the refrigerator is maintained.

また、本発明の冷蔵庫は、冷蔵室冷却パイプが冷却プレートを介して内箱の背面の断熱材側に取付けられた直冷式冷蔵庫で、内箱背面が、庫内側に傾斜した傾斜面を上部に、傾斜面より下部に垂直面を持ち、前記冷却プレートも、前記内箱背面の傾斜面と垂直面に密着配置するよう、傾斜面を上部に、傾斜面より下部に垂直面を持たせ、内箱の傾斜面が最上部の庫内棚の鉛直線上の上方に位置させ、最上部のドア棚の上端よりも最上部の庫内棚の食品塔載面が上部に位置させたことで、冷蔵室冷却パイプによって冷却された冷却プレートが内箱を冷却し、内箱により冷却された空気は自然対流により冷蔵室内を循環することで冷蔵室内が冷却される。冷却された空気は比重が大きくなり冷蔵室の下方に移動するが、内箱の傾斜面により冷却された空気は傾斜面の下部に位置している最上部の庫内棚の食品搭載面で受けられる。食品搭載面で受けられた空気は食品搭載面上を前後左右へと拡散しさらに冷蔵室の下方へと移動するが、前部に移動した空気は食品搭載面より下部に最上部のドア棚が位置しているため、最上部のドア棚に移動する。つまり、内箱の傾斜面から最上部のドア棚まで、冷却された空気の風路が形成されているため、最上部のドア棚の温度を低減することができる。内箱の傾斜面についた除霜水は傾斜面に沿って流れるためドレン部に確実に導かれるため、冷蔵庫の排水性機能は維持される。 The refrigerator of the present invention is a direct cooling refrigerator in which the refrigerator compartment cooling pipe is attached to the heat insulating material side of the back of the inner box through the cooling plate, and the inner box back has an inclined surface that is inclined to the inside of the warehouse. In addition, it has a vertical surface below the inclined surface, and the cooling plate also has a vertical surface on the upper side and a lower surface than the inclined surface so that the cooling plate is arranged in close contact with the inclined surface and the vertical surface on the back of the inner box, By positioning the inclined surface of the inner box above the vertical line of the uppermost shelf, and placing the food tower mounting surface of the uppermost shelf above the upper end of the uppermost door shelf, The cooling plate cooled by the refrigerator compartment cooling pipe cools the inner box, and the air cooled by the inner box circulates in the refrigerator compartment by natural convection, thereby cooling the refrigerator compartment. The cooled air increases in specific gravity and moves below the refrigerator compartment, but the air cooled by the inclined surface of the inner box is received by the food loading surface of the uppermost shelf in the lower part of the inclined surface. It is done. The air received on the food loading surface diffuses forward, backward, left and right on the food loading surface, and further moves downward in the refrigerator compartment, but the air moved to the front has an uppermost door shelf below the food loading surface. Because it is located, it moves to the top door shelf. That is, since the air path of the cooled air is formed from the inclined surface of the inner box to the uppermost door shelf, the temperature of the uppermost door shelf can be reduced. Since the defrost water on the inclined surface of the inner box flows along the inclined surface, it is reliably guided to the drain portion, so that the drainage function of the refrigerator is maintained.

また、本発明の冷蔵庫は、最上部の庫内棚が食品を塔載するための食品塔載面と内箱の背面に付着した除霜水を受ける棚ドレン部からなり、食品塔載面は前部に、棚ドレン部は後部に位置させ、棚ドレン部は除霜水をドレン部に導くための棚排水管部を有し、最上部のドア棚の上端よりも前記食品塔載面が上部に位置させたことで、最上部の庫内棚の食品搭載面へ除霜水が流れこまないので、最上部の庫内棚は内箱背面と接触配置が可能となり、最上部の庫内棚と内箱背面の隙間はほぼ無くすことができ、冷却され比重が大きくなり冷蔵室の下方へと移動する空気は最上部の棚で受けることとなる。最上部の棚で受けられた空気は最上部の棚上を前後左右へと拡散しさらに冷蔵室の下方へと移動するが、前部に移動した空気は食品搭載面より下部に最上部のドア棚が位置しているため、最上部のドア棚に移動する。つまり、内箱背面から最上部のドア棚まで、冷却された空気の風路が形成されているため、最上部のドア棚の温度を低減することができる。 In addition, the refrigerator of the present invention comprises a food tower mounting surface on which the uppermost shelf in the cabinet is mounted with food and a shelf drain portion that receives defrost water attached to the back of the inner box, At the front part, the shelf drain part is located at the rear part, the shelf drain part has a shelf drain pipe part for guiding defrost water to the drain part, and the food tower mounting surface is more than the upper end of the uppermost door shelf. By positioning it at the top, defrost water does not flow into the food loading surface of the top shelf, so the top shelf can be placed in contact with the back of the inner box, The gap between the shelf and the back of the inner box can be almost eliminated, and the air that is cooled and increases in specific gravity and moves downward in the refrigerator compartment is received by the uppermost shelf. The air received on the top shelf diffuses from front to back and left and right on the top shelf and then moves to the lower side of the refrigeration room. Since the shelf is located, it moves to the top door shelf. That is, since the air path of the cooled air is formed from the back of the inner box to the uppermost door shelf, the temperature of the uppermost door shelf can be reduced.

また、本発明の冷蔵庫は、最上部の庫内棚の食品搭載面よりも高い位置の内箱背面に、上部ドレン部と上部ドレン部の一部が冷蔵室外と連通した上部排水管部を備え、最上部のドア棚の上端よりも前記食品塔載面が上部に位置させたことで、最上部の庫内棚の食品搭載面へ除霜水が流れこまないので、最上部の庫内棚は内箱背面と接触配置が可能となり、最上部の庫内棚と内箱背面の隙間はほぼ無くすことができ、冷却され比重が大きくなり冷蔵室の下方へと移動する空気は最上部の棚の食品搭載面で受けることとなる。食品搭載面で受けられた空気は食品搭載面上を前後左右へと拡散しさらに冷蔵室の下方へと移動するが、前部に移動した空気は食品搭載面より下部に最上部のドア棚が位置しているため、最上部のドア棚に移動する。つまり、内箱背面から最上部のドア棚まで、冷却された空気の風路が形成されているため、最上部のドア棚の温度を低減することができる。 In addition, the refrigerator of the present invention includes an upper drain pipe part and an upper drain pipe part in which a part of the upper drain part communicates with the outside of the refrigerator compartment on the back of the inner box at a position higher than the food mounting surface of the uppermost shelf. Since the food tower mounting surface is positioned above the upper end of the uppermost door shelf, defrost water does not flow to the food mounting surface of the uppermost shelf, so the uppermost shelf Can be placed in contact with the back of the inner box, and there is almost no gap between the top shelf in the cabinet and the back of the inner box, and the air that is cooled and increases in specific gravity moves downward in the refrigerator compartment. It will be received on the food loading side. The air received on the food loading surface diffuses forward, backward, left and right on the food loading surface, and further moves downward in the refrigerator compartment, but the air moved to the front has an uppermost door shelf below the food loading surface. Because it is located, it moves to the top door shelf. That is, since the air path of the cooled air is formed from the back of the inner box to the uppermost door shelf, the temperature of the uppermost door shelf can be reduced.

請求項１に記載の発明は、冷蔵室冷却パイプが内箱の背面の断熱材側に取付けられた直冷式冷蔵庫の冷蔵室内に、上部が庫内側に傾斜した傾斜面を有するアルミプレートを内箱背面に取り付け、前記傾斜面が最上部の庫内棚の鉛直線上の上方に位置させ、最上部のドア棚の上端よりも最上部の庫内棚の食品塔載面を上部に位置させたことで、冷蔵室冷却パイプによって冷却された内箱が、アルミプレートを冷却し、アルミプレートにより冷却された空気は自然対流により冷蔵室内を循環することで冷蔵室内が冷却される。冷却された空気は比重が大きくなり冷蔵室の下方に移動するが、アルミプレートの傾斜面により冷却された空気は傾斜面の下部に位置している最上部の庫内棚の食品搭載面で受けられる。食品搭載面で受けられた空気は食品搭載面上を前後左右へと拡散しさらに冷蔵室の下方へと移動するが、前部に移動した空気は食品搭載面より下部に最上部のドア棚が位置しているため、最上部のドア棚に移動する。つまり、アルミプレートから最上部のドア棚まで、冷却された空気の風路が形成されているため、最上部のドア棚の温度を低減することができる。 According to the first aspect of the present invention, an aluminum plate having an inclined surface whose upper part is inclined toward the inside of the refrigerator is provided in the refrigerating room of the direct cooling refrigerator in which the refrigerating room cooling pipe is attached to the heat insulating material side of the back of the inner box. Attached to the back of the box, the inclined surface is positioned above the vertical line of the uppermost shelf, and the food tower mounting surface of the uppermost shelf is positioned above the upper end of the uppermost door shelf. Thus, the inner box cooled by the refrigerating room cooling pipe cools the aluminum plate, and the air cooled by the aluminum plate circulates in the refrigerating room by natural convection, thereby cooling the refrigerating room. The cooled air has a higher specific gravity and moves downward in the refrigerator compartment, but the air cooled by the inclined surface of the aluminum plate is received by the food mounting surface of the uppermost shelf in the lower part of the inclined surface. It is done. The air received on the food loading surface diffuses forward, backward, left and right on the food loading surface, and further moves downward in the refrigerator compartment, but the air moved to the front has an uppermost door shelf below the food loading surface. Because it is located, it moves to the top door shelf. That is, since the air path of the cooled air is formed from the aluminum plate to the uppermost door shelf, the temperature of the uppermost door shelf can be reduced.

請求項２に記載の発明は、冷蔵室冷却パイプが冷却プレートを介して内箱の背面の断熱材側に取付けられた直冷式冷蔵庫で、内箱背面が、庫内側に傾斜した傾斜面を上部に、傾斜面より下部に垂直面を持ち、前記冷却プレートも、前記内箱背面の傾斜面と垂直面に密着配置するよう、傾斜面を上部に、傾斜面より下部に垂直面を持たせ、内箱の傾斜面が最上部の庫内棚の鉛直線上の上方に位置させ、最上部のドア棚の上端よりも最上部の庫内棚の食品塔載面が上部に位置させたことで、冷蔵室冷却パイプによって冷却された冷却プレートが内箱を冷却し、内箱により冷却された空気は自然対流により冷蔵室内を循環することで冷蔵室内が冷却される。冷却された空気は比重が大きくなり冷蔵室の下方に移動するが、内箱の傾斜面により冷却された空気は傾斜面の下部に位置している最上部の庫内棚の食品搭載面で受けられる。食品搭載面で受けられた空気は食品搭載面上を前後左右へと拡散しさらに冷蔵室の下方へと移動するが、前部に移動した空気は食品搭載面より下部に最上部のドア棚が位置しているため、最上部のドア棚に移動する。つまり、内箱の傾斜面から最上部のドア棚まで、冷却された空気の風路が形成されているため、最上部のドア棚の温度を低減することができる。 The invention according to claim 2 is a direct cooling refrigerator in which the refrigerator compartment cooling pipe is attached to the heat insulating material side of the back of the inner box through the cooling plate, and the inner box back has an inclined surface inclined to the inside of the refrigerator. The upper surface has a vertical surface below the inclined surface, and the cooling plate also has an inclined surface on the upper side and a vertical surface below the inclined surface so that the cooling plate is closely attached to the inclined surface and the vertical surface on the back of the inner box. The slanted surface of the inner box is positioned above the vertical line of the uppermost shelf, and the food tower mounting surface of the uppermost shelf is positioned above the upper end of the uppermost door shelf. The cooling plate cooled by the refrigerating room cooling pipe cools the inner box, and the air cooled by the inner box circulates in the refrigerating room by natural convection, thereby cooling the refrigerating room. The cooled air increases in specific gravity and moves below the refrigerator compartment, but the air cooled by the inclined surface of the inner box is received by the food loading surface of the uppermost shelf in the lower part of the inclined surface. It is done. The air received on the food loading surface diffuses forward, backward, left and right on the food loading surface, and further moves downward in the refrigerator compartment, but the air moved to the front has an uppermost door shelf below the food loading surface. Because it is located, it moves to the top door shelf. That is, since the air path of the cooled air is formed from the inclined surface of the inner box to the uppermost door shelf, the temperature of the uppermost door shelf can be reduced.

請求項３に記載の発明は、最上部の庫内棚が食品を塔載するための食品塔載面と内箱の背面に付着した除霜水を受ける第二のドレン部からなり、食品塔載面は前部に、棚ドレン部は後部に位置させ、棚ドレン部は除霜水をドレン部に導くための棚排水管部を有し、最上部のドア棚の上端よりも前記食品塔載面が上部に位置させたことで、最上部の庫内棚の食品搭載面へ除霜水がに流れこまないので、最上部の庫内棚は内箱背面と接触配置が可能となり、最上部の庫内棚と内箱背面の隙間はほぼ無くすことができ、冷却され比重が大きくなり冷蔵室の下方へと移動する空気は最上部の棚で受けることとなる。最上部の棚で受けられた空気は最上部の棚上を前後左右へと拡散しさらに冷蔵室の下方へと移動するが、前部に移動した空気は食品搭載面より下部に最上部のドア棚が位置しているため、最上部のドア棚に移動する。つまり、内箱背面から最上部のドア棚まで、冷却された空気の風路が形成されているため、最上部のドア棚の温度を低減することができる。 The invention according to claim 3 is a food tower comprising a food tower mounting surface on which the uppermost cabinet shelf mounts food and a second drain portion for receiving defrost water adhering to the back of the inner box. The loading surface is located at the front, the shelf drain part is located at the rear, the shelf drain part has a shelf drain pipe part for guiding defrost water to the drain part, and the food tower is located above the upper end of the uppermost door shelf. By placing the loading surface at the top, defrost water does not flow into the food loading surface of the uppermost shelf, so the uppermost shelf can be placed in contact with the back of the inner box, The gap between the upper internal shelf and the back of the inner box can be almost eliminated, and the air that is cooled and increases in specific gravity and moves downward in the refrigerator compartment is received by the uppermost shelf. The air received on the top shelf diffuses from front to back and left and right on the top shelf and then moves to the lower side of the refrigeration room. Since the shelf is located, it moves to the top door shelf. That is, since the air path of the cooled air is formed from the back of the inner box to the uppermost door shelf, the temperature of the uppermost door shelf can be reduced.

請求項４に記載の発明は、最上部の庫内棚の食品搭載面よりも高い位置の内箱背面に、上部ドレン部と上部ドレン部の一部が冷蔵室外と連通した上部排水管部を備え、最上部のドア棚の上端よりも前記食品塔載面が上部に位置させたことで、最上部の庫内棚の食品搭載面へ除霜水が流れこまないので、最上部の庫内棚は内箱背面と接触配置が可能となり、最上部の庫内棚と内箱背面の隙間はほぼ無くすことができ、冷却され比重が大きくなり冷蔵室の下方へと移動する空気は最上部の棚の食品搭載面で受けることとなる。食品搭載面で受けられた空気は食品搭載面上を前後左右へと拡散しさらに冷蔵室の下方へと移動するが、前部に移動した空気は食品搭載面より下部に最上部のドア棚が位置しているため、最上部のドア棚に移動する。つまり、内箱背面から最上部のドア棚まで、冷却された空気の風路が形成されているため、最上部のドア棚の温度を低減することができる。 The invention according to claim 4 is characterized in that an upper drain pipe part in which the upper drain part and a part of the upper drain part are communicated with the outside of the refrigerator compartment is provided on the inner box rear surface at a position higher than the food mounting surface of the uppermost shelf. The defrost water does not flow into the food loading surface of the top shelf in the top cabinet because the food tower mounting surface is positioned above the upper end of the top door shelf. The shelf can be placed in contact with the back of the inner box, the gap between the uppermost shelf in the cabinet and the back of the inner box can be almost eliminated, and the air that is cooled and increases in specific gravity moves downward in the refrigerator compartment. It will be received on the food loading side of the shelf. The air received on the food loading surface diffuses forward, backward, left and right on the food loading surface, and further moves downward in the refrigerator compartment, but the air moved to the front has an uppermost door shelf below the food loading surface. Because it is located, it moves to the top door shelf. That is, since the air path of the cooled air is formed from the back of the inner box to the uppermost door shelf, the temperature of the uppermost door shelf can be reduced.

以下、本発明の実施の形態について、図面を参照しながら説明する。なお、この実施の形態によってこの発明が限定されるものではない。 Hereinafter, embodiments of the present invention will be described with reference to the drawings. The present invention is not limited to the embodiments.

図１，２，３において１８は冷蔵庫本体であり、上室の冷蔵室１９の背面には、アルミプレート２０が取付けられている。２１はアルミプレートの傾斜面であり、第１の庫内棚２２の食品搭載面２３の鉛直線上の上方に位置している。２４は第１のドア棚であり第１のドア棚２４のドア棚上端２４ａは食品搭載面２３の下に位置している。 In FIGS. 1, 2, and 3, reference numeral 18 denotes a refrigerator main body, and an aluminum plate 20 is attached to the back surface of the upper refrigerator compartment 19. 21 is an inclined surface of the aluminum plate, and is positioned above the vertical line of the food mounting surface 23 of the first internal shelf 22. Reference numeral 24 denotes a first door shelf, and a door shelf upper end 24 a of the first door shelf 24 is located below the food mounting surface 23.

以上のように構成された冷蔵庫について、以下その動作、作用について説明する。 About the refrigerator comprised as mentioned above, the operation | movement and an effect | action are demonstrated below.

冷蔵室冷却パイプ１３により内箱３が冷却され、内箱３によりアルミプレート２０が冷却され、冷蔵室１９内は、そのアルミプレート２０によって冷却された空気が自然対流で循環することで冷やされる。傾斜面２１によって冷やされた空気は比重が大きくなるため下方に移動するが、傾斜面２１の鉛直方向の下部には第１の庫内棚２２が位置しているため、傾斜面２１で冷却された空気は第１の庫内棚２２の食品搭載面２３で受けられる。食品搭載面２３で受けられた空気は食品搭載面２３上を前後左右へと拡散しさらに冷蔵室１９の下方へと移動するが、前部に移動した空気は食品搭載面２３より下部に第１のドア棚２４の上端２４ａが位置しているため、第１のドア棚２４に移動する。つまり、アルミプレート２０から第１のドア棚２４まで、冷却された空気の風路が形成されているため、第１のドア棚２４の温度を低減することができる。アルミプレート２０の傾斜面２１についた除霜水は傾斜面２１に沿って流れるため第１のドレン部１６に確実に導かれるため、冷蔵庫の排水性機能は維持される。 The inner box 3 is cooled by the refrigerating room cooling pipe 13, the aluminum plate 20 is cooled by the inner box 3, and the inside of the refrigerating room 19 is cooled by circulating the air cooled by the aluminum plate 20 by natural convection. The air cooled by the inclined surface 21 moves downward because of its increased specific gravity, but is cooled by the inclined surface 21 because the first internal shelf 22 is located at the lower part of the inclined surface 21 in the vertical direction. The air is received by the food mounting surface 23 of the first internal shelf 22. The air received by the food loading surface 23 diffuses on the food loading surface 23 in the front, rear, left, and right directions, and further moves downward in the refrigerator compartment 19, but the air that has moved to the front is first below the food loading surface 23. Since the upper end 24 a of the door shelf 24 is positioned, the door shelf 24 moves to the first door shelf 24. That is, since the air path of the cooled air is formed from the aluminum plate 20 to the first door shelf 24, the temperature of the first door shelf 24 can be reduced. Since the defrost water attached to the inclined surface 21 of the aluminum plate 20 flows along the inclined surface 21, the defrost water is reliably guided to the first drain portion 16, so that the drainage function of the refrigerator is maintained.

It is cooled by circulating the air cooled by natural convection. The air cooled by the inclined surface 31 on the back surface of the inner box 30 moves downward because the specific gravity increases, but since the first internal shelf 22 is located at the lower part of the inclined surface 31 in the vertical direction, The air cooled by the inclined surface 31 is received by the food mounting surface 23 of the first internal shelf 22. The air received by the food loading surface 23 diffuses on the food loading surface 23 in the front / rear and left / right directions, and further moves downward in the refrigerator compartment 27. However, the air moved to the front is first below the food loading surface 23. Since the upper end 24 a of the door shelf 24 is positioned, the door shelf 24 moves to the first door shelf 24. That is, since the air path of the cooled air is formed from the inner box 30 to the first door shelf 24, the temperature of the first door shelf 24 can be reduced. Since the defrost water attached to the inclined surface 31 of the inner box 30 flows along the inclined surface 31, the defrosted water is reliably guided to the first drain portion 16, so that the drainage function of the refrigerator is maintained.

As a result, the air above the first internal shelf 37 is cooled by the inner box 3 and increases in specific gravity, and moves downward in the refrigerator compartment 36. However, the first box provided with no gap from the inner box 3 is provided. Received on shelf 37. The air received by the first shelf 37 diffuses in the front / rear / left / right direction on the first shelf 37 and further moves downward in the refrigerator compartment 36, but the air moved to the front is below the food loading surface 38. Since the upper end 24 a of the first door shelf 24 is located, the first door shelf 24 moves to the first door shelf 24. That is, since the air path of the cooled air is formed from the inner box 3 to the first door shelf 24, the temperature of the first door shelf 24 can be reduced.

FIG. 8 is a cross-sectional view of the refrigerator in the third embodiment of the present invention. FIG. 9 is a front view of the refrigerating room according to Embodiment 3 of the present invention.

図８、図９において、４１は冷蔵庫本体であり、上室の冷蔵室４２の内箱４３の背面には、第１の棚２２の上方に第２のドレン部４４と第２のドレン部４４の一部には冷蔵室４２外と連通している第２の排水管部４５を設けている。 In FIGS. 8 and 9, reference numeral 41 denotes a refrigerator main body. On the back surface of the inner box 43 of the upper refrigerator compartment 42, a second drain portion 44 and a second drain portion 44 are disposed above the first shelf 22. A second drain pipe 45 that communicates with the outside of the refrigerating chamber 42 is provided in a part thereof.

第１の庫内棚２２より上方からの除霜水は第２のドレン部４４で受けられるので、第１の庫内棚２２は内箱４３の背面と隙間無く備えることができる。その結果、第１の庫内棚２２の上方にある空気は内箱４３により冷却され比重が大きくなり、冷蔵室４２の下方へ移動するが、内箱４３と隙間無く備えられている第１の棚２２で受けられる。第１の棚２２で受けられた空気は第１の棚２２の食品搭載面２３上を前後左右へと拡散しさらに冷蔵室４２の下方へと移動するが、前部に移動した空気は食品搭載面２３より下部に第１のドア棚２４の上端２４ａが位置しているため、第１のドア棚２４に移動する。つまり、内箱３から第１のドア棚２４まで、冷却された空気の風路が形成されているため、第１のドア棚２４の温度を低減することができる。 Since defrost water from above the first internal shelf 22 is received by the second drain part 44, the first internal shelf 22 can be provided with no gap from the back surface of the inner box 43. As a result, the air above the first internal shelf 22 is cooled by the inner box 43 and increases in specific gravity, and moves downward of the refrigerator compartment 42. However, the first box provided with no gap from the inner box 43 is provided. Received on shelf 22. The air received by the first shelf 22 diffuses on the food mounting surface 23 of the first shelf 22 to the front, rear, left and right, and further moves to the lower side of the refrigerator compartment 42, but the air moved to the front is loaded with food. Since the upper end 24 a of the first door shelf 24 is located below the surface 23, the first door shelf 24 moves to the first door shelf 24. That is, since the air path of the cooled air is formed from the inner box 3 to the first door shelf 24, the temperature of the first door shelf 24 can be reduced.

以上のように、本発明にかかる冷蔵庫は、最上部に位置する庫内棚の食品搭載面にその上方から移動してくる空気を受け、食品搭載面より下に位置している最上部のドア棚に空気を導くことで最上部のドア棚温度を低減することができる。 As described above, the refrigerator according to the present invention receives the air moving from above the food mounting surface of the inner shelf located at the uppermost portion, and is the uppermost door positioned below the food mounting surface.
