Description

【0001】
【発明の属する技術分野】
本発明は冷蔵庫に係り、特に貯蔵室内の冷却効率を向上させる冷気流路構成の改良に関する。
【0002】
【従来の技術】
従来、冷蔵庫における冷凍空間と冷蔵空間のそれぞれに冷却器を設け、この冷凍用冷却器と冷蔵用冷却器とを冷凍サイクル中の切換弁を切り換えて交互に冷却し、ファンによって冷気を循環させることで、冷凍および冷蔵空間を所定温度に冷却するようにした冷蔵庫が存在する。
【0003】
この冷蔵庫は、前記構成により、冷凍用と冷蔵用各冷却器の蒸発温度とそれぞれの対応する貯蔵室の設定冷却温度との差を小さくすることができるため、特に冷蔵空間については室内の水分が霜となって冷蔵用冷却器に付着することを極力抑えることができ、その結果、室内の乾燥を防いで貯蔵食品にうるおいを与え長期保存に寄与する効果を奏するものである。
【0004】
上記冷蔵庫の冷蔵空間における冷気の循環は、図3に示すように、野菜室(45)の背部に設置した断熱部材からなる冷却器カバー(59)によって冷却器室(54)を形成し、この冷却器室(54)に設置した冷蔵用冷却器(52)で生成した冷気をファン(53)によって上方の背面ダクト(57)に吐出し、冷蔵室(42)の背面に上下に亙って形成した図示しない複数の吹出口から室内に吹き出して棚上に載置されている食品類を冷却するよう構成されている。
【0005】
そして、冷蔵室(42)を循環した冷気は、冷蔵室の背面下部から矢印に示すように、野菜室(45)内に流入し、引き出し式になっている貯蔵ケース(40)の上面に設けた蓋カバー(51)と室内天井部との間隙を通って前方上部に至り、引き出し扉(48)の内板(48a)と貯蔵ケース(40)の前面との間隙、さらに貯蔵ケース(40)底面と野菜室底壁との間隙を通ってリターン通路(50)から冷蔵用冷却器(52)に戻る循環をおこなう構成である。(例えば、特許文献1参照)
【0006】
【特許文献1】
特開平11−311476号公報(段落[0037]および図4)
【0007】
【発明が解決しようとする課題】
しかしながら、上記構成は、貯蔵ケース(40)の上部に配設した上ケース(41)の上部を蓋カバー(51)で覆うことでケース内の乾燥をより防止するものであるが、引き出し扉方式であるため、引き出し時には蓋カバー(51)は本体側に残る機構であり、貯蔵ケース(40)の前方上部は開口しているとともに、全体的にもケースの内外には比較的隙間も存在することから、貯蔵ケース(40)内に冷気が侵入することによって食品の乾燥が進み、高湿度の環境を保持することは困難であった。また、蓋カバー(51)や冷却器カバー(59)の裏面に断熱成形体(60)を設けて冷却器カバー(59)への露付きを防止する必要があるなど構造的にも複雑であった。
【0008】
本発明は上記事情を考慮してなされたものであり、野菜室内を適正温度に冷却し、且つ高湿度雰囲気に保持する構成を得るとともに、構造を間単にして部品数を削減し、コストダウンを図ることができる冷蔵庫を提供するものである。
【0009】
【課題を解決するための手段】
上記課題を解決するため本発明の冷蔵庫は、冷凍空間と冷蔵空間とを有し冷凍用冷却器と冷蔵用冷却器を設けてそれぞれの空間を前記各冷却器により所定温度に冷却するようにした冷蔵庫において、冷蔵室温より少許高温度に制御した野菜室の背面に冷蔵用冷却器を対向配置し、この冷蔵用冷却器を覆う冷却器カバーの前面に冷蔵室からの戻り冷気ダクトを配設したことを特徴とするものである。
【0010】
この構成により、冷気ダクトによる間接冷却で野菜室内の貯蔵品を良好に冷却できるとともに、湿度を高く保って貯蔵品の鮮度を長期に亙って持続することができる。さらに構造をシンプルにできることで部品数を削減し、以てコスト削減を低減することができ、また、効率的な冷却によって消費電力量を低減することができる。
【0011】
【発明の実施の形態】
以下、図面に基づき本発明の一実施形態について説明する。冷蔵庫の縦断面図である図1に示すように、断熱箱体で構成され、内部を断熱壁で区分して複数の貯蔵空間を形成した冷蔵庫本体(1)は、その上部に使用頻度が多く収納容積の最も大きい冷蔵室(2)を配置し、本体一側に回動自在に枢支した扉(3)によってその前面開口部を閉塞している。
【0012】
冷蔵室(2)の下方には、薄板状の仕切板(4)を介して冷蔵室温よりやや高い温度に保持された野菜や果物などを収納する野菜室(5)を設置し、野菜室(5)の下部には、従来と同様に断熱仕切壁を介して、室内温度を多温度に切り替える温度切替室(6)やこれに併設した図示しない自動製氷装置を設けた製氷室を設け、その下部には冷凍室(7)をそれぞれ独立して配置している。
【0013】
これら野菜室(4)や冷凍室(7)は、その前面開口部を扉(8)(9)で閉塞するとともに、扉の内側に貯蔵室内方向に延長する枠体を取り付け、この枠体上面にそれぞれ貯蔵ケース(10)(11)を載置し、前記枠体の後端に取り付けたローラーと庫内壁に設けた図示しないレール部材などとの係合による摺動によって、貯蔵ケース(10)(11)を扉(8)(9)の開閉で前後方向に引き出し可能に設けている。
【0014】
野菜室(5)の背部には、前記冷蔵室(2)や野菜室(5)などの冷蔵空間へ冷気を供給してそれぞれの冷蔵温度に冷却する冷蔵用冷却器(12)を設置しており、この冷却器(12)の上部には冷気を循環させるファン(13)を配置して冷却器室(14)を形成している。
【0015】
なお、前記温度切替室(6)や製氷室、冷凍室(7)などの冷凍空間に対しても冷凍用冷却器(15)および冷凍用ファン(16)が冷凍室(7)の背部に設置されており、吐出ダクトからの冷気を冷気吹出口に導き、温度切替室(6)や製氷室、および冷凍室(7)を所定の設定温度に冷却するよう制御している。
【0016】
冷蔵用冷却器(12)で冷却された冷気は、図2に詳細を示すように、上部に設置したファン(13)によって上方の冷蔵室背面ダクト(17)に吐出されるものであり、背面ダクト(17)からの冷気はダクト面の上下に亙る複数箇所に穿設された冷気吹出口(18)から冷蔵室(2)内に吹き出し、室内を循環して貯蔵品を冷却する。
【0017】
前記冷蔵用冷却器(12)とファン(13)の前面は、野菜室(5)の後壁を形成する冷却器カバー(19)で覆われているとともに、冷却器カバー(19)の野菜室(5)側には幅方向に亙る冷気流通間隙を上下に設けてなる冷気ダクト(20)を配設しており、冷蔵室(2)の底面後部からの戻り冷気をダクト(20)内に導入して流下させ、下方から冷却器室(14)に吸い込んで再び冷却し循環させるようにしている。
【0018】
そして、前記冷気ダクト(20)は、アルミニウム薄板の成形体で形成するとともに、その上端縁は前方の開口部近傍まで延出して冷蔵室(2)と野菜室(5)との仕切板(4)を構成しており、また、ダクトの下端は、冷却器室(14)の下部に配置した冷却器(12)の除霜水を受けて庫外に排出する排水樋(21)に当接させている。
【0019】
したがって、冷蔵室(2)からの冷気は野菜室(5)内に流入することはなく、野菜室(5)は冷蔵室との仕切板(4)や冷気ダクト(20)の表面からの間接的な冷却により所定温度に冷却されるものであり、野菜室扉(8)の閉扉時には密閉状態を保持して空気中の水分の流出を防ぎ、室内を高湿度環境に保って野菜などの乾燥を防ぎ、鮮度を長期に亙って保つことができる。同時に、冷気を野菜室(5)内に流さないことで冷却のための風量が低減できることからファン(13)の回転数やモータ入力を低減でき、省電力効果が得られる。
【0020】
さらに、冷気ダクト(20)および上部の仕切板(4)は、良熱伝導体であるアルミニウムの薄板で形成しているため、より温度の低い冷蔵室(2)の底面部、および冷気流で低温となっている冷気ダクト(20)の輻射冷却による温度影響を受けて上面および背面から効率的に野菜室(5)内を適温、例えば、4℃程度に均一に冷却することができるものである。
【0021】
冷蔵用冷却器(12)の前面を覆う冷却器カバー(19)は、野菜室(5)に面しており、従来は低温の冷却器室(12)と比較的高温の野菜室(5)との温度差によりカバー(19)表面に露が付くことを防ぐため、冷却器(12)側に発泡スチロールなどの成形体(60)による断熱層を設けていたが、本発明では断熱成形体は使用せず、冷却器カバー(19)の野菜室(5)側の面に冷気ダクト(20)を設けていることから、冷却器カバー(19)の表面には常に冷気が流通し、その蒸発作用により結露することを防いでいる。
【0022】
また、たとえ冷却器(12)との温度差が大きくなった際に結露を生じ、滴下したとしても、冷気ダクト(20)の下端は排水樋(21)に連通していることから、露水はダクトから排水樋(21)に流下し庫外に排水されるため何ら問題はなく、結露によって外観を損なうこともない。
【0023】
したがって、上記構成によれば、従来必要であった貯蔵ケース(10)の上面を覆ってケース内の乾燥を防止する蓋カバー(51)を必要とせず、また、冷却器カバー(19)と冷却器(12)間の成形断熱材(60)も配置することなく高湿度の保持、および結露することを防止できるため、部品数の削減ができるとともに構成の簡素化が可能となる。
【0024】
さらに従来は、冷蔵室温度を検知する温度センサーを冷蔵室内に配置していたが、本実施例においては、前記冷却器カバー(19)の前面における冷気ダクト(20)の内部に温度センサー(22)を設置するようにした。これにより、外気温や貯蔵品温度などの影響を受けることなく冷蔵室(2)からの戻り冷気の温度を正確に検知することができる。
【0025】
上記実施例においては、野菜室(5)背面の冷気ダクト(20)および野菜室の天井部を形成する冷蔵室(2)との仕切板(4)をアルミニウム薄板で形成したが、野菜室内を所定温度に冷却する冷却力が得られれば、アルミニウム薄板に限らず合成樹脂板などによる成形体でもよく、また一部のみを良熱伝導体で形成するようにしてもよい。
【0026】
【発明の効果】
本発明は上記のように構成されており、冷気ダクトによる間接冷却で野菜室内の貯蔵品を良好に冷却できるとともに、野菜室内の湿度を高く保って貯蔵品の鮮度を長期に亙って持続することができる。さらに構造をシンプルにできることで部品数を削減し、以てコスト削減を低減することができ、また、効率的な冷却によって消費電力量を低減することができる。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a refrigerator and, more particularly, to an improvement in a configuration of a cool air flow path for improving cooling efficiency in a storage room.
[0002]
[Prior art]
Conventionally, a refrigerator is provided in each of a freezing space and a refrigeration space in a refrigerator, and the refrigeration cooler and the refrigeration cooler are alternately cooled by switching a switching valve in a refrigeration cycle, and cool air is circulated by a fan. There is a refrigerator that cools a freezing and refrigeration space to a predetermined temperature.
[0003]
With this configuration, the refrigerator can reduce the difference between the evaporation temperature of each of the refrigerators for freezing and refrigeration and the set cooling temperature of the corresponding storage room. It is possible to minimize the formation of frost and adhering to the cooler for refrigeration, and as a result, it is possible to prevent indoor drying and to provide moisture to the stored food, thereby contributing to long-term storage.
[0004]
As shown in FIG. 3, the circulation of the cool air in the refrigerator space of the refrigerator forms a cooler room (54) by a cooler cover (59) made of a heat insulating member installed at the back of the vegetable room (45). Cool air generated by the refrigerator cooler (52) installed in the cooler room (54) is discharged to the upper rear duct (57) by the fan (53), and extends vertically on the rear surface of the refrigerator room (42). It is configured to blow out into the room from a plurality of formed outlets (not shown) to cool the foods placed on the shelf.

(For example, see Patent Document 1)
[0006]
[Patent Document 1]
JP-A-11-31476 (paragraph [0037] and FIG. 4)
[0007]
[Problems to be solved by the invention]
However, the above-mentioned configuration is to prevent the inside of the case from being dried more by covering the upper part of the upper case (41) disposed on the upper part of the storage case (40) with the lid cover (51). Therefore, the lid cover (51) is a mechanism that remains on the main body side at the time of pulling out, and the upper front part of the storage case (40) is open, and there is also a relatively large gap inside and outside the case as a whole. Therefore, the drying of the food proceeds due to the intrusion of cold air into the storage case (40), and it has been difficult to maintain a high humidity environment. In addition, it is structurally complicated that it is necessary to provide a heat insulating molded body (60) on the back surface of the lid cover (51) or the cooler cover (59) to prevent the cooler cover (59) from being exposed. Was.
[0008]
The present invention has been made in consideration of the above circumstances, and provides a configuration in which a vegetable room is cooled to an appropriate temperature and maintained in a high-humidity atmosphere, the number of parts is reduced by simplifying the structure, and cost is reduced. It is intended to provide a refrigerator capable of achieving the following.
[0009]
[Means for Solving the Problems]
In order to solve the above problems, the refrigerator of the present invention has a freezing space and a refrigerated space, and is provided with a freezing cooler and a refrigerated cooler, and each space is cooled to a predetermined temperature by each of the coolers. In the refrigerator, a cooler for cooling was arranged opposite to the back of the vegetable room controlled at a temperature slightly higher than the room temperature of the refrigerator, and a return air duct from the refrigerator was arranged in front of the cooler cover covering this cooler. It is characterized by the following.
[0010]
With this configuration, it is possible to satisfactorily cool the stored items in the vegetable room by indirect cooling by the cool air duct, and to keep the humidity high to maintain the freshness of the stored items for a long time. Furthermore, since the structure can be simplified, the number of parts can be reduced, thereby reducing the cost. In addition, power consumption can be reduced by efficient cooling.
[0011]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, an embodiment of the present invention will be described with reference to the drawings. As shown in FIG. 1 which is a longitudinal sectional view of the refrigerator, the refrigerator body (1), which is constituted by a heat insulating box and has a plurality of storage spaces formed by partitioning the inside with heat insulating walls, is frequently used at the upper part thereof. A refrigerating room (2) having the largest storage volume is arranged, and a front opening is closed by a door (3) rotatably supported on one side of the main body.
[0012]
A vegetable compartment (5) for storing vegetables and fruits kept at a temperature slightly higher than the refrigerated room temperature via a thin plate-like partition plate (4) is installed below the refrigerator compartment (2). In the lower part of 5), a temperature switching chamber (6) for switching the room temperature to multiple temperatures and an ice making chamber provided with an automatic ice making device (not shown) provided in the lower part are provided through a heat insulating partition wall as in the related art. In the lower part, the freezing compartments (7) are independently arranged.
[0013]
These vegetable compartments (4) and freezer compartments (7) have their front openings closed by doors (8) and (9), and a frame extending in the direction of the storage compartment is attached inside the door. The storage cases (10) and (11) are placed on the storage case (10), respectively, and the storage case (10) is slid by engagement between a roller attached to the rear end of the frame and a rail member (not shown) provided on the inner wall of the refrigerator. (11) is provided so that it can be pulled out in the front-rear direction by opening and closing the doors (8) and (9).
[0014]
At the back of the vegetable compartment (5), a refrigerator cooler (12) for supplying cold air to the refrigerator compartments such as the refrigerator compartment (2) and the vegetable compartment (5) to cool to the respective refrigerator temperatures is installed. A fan (13) for circulating cool air is disposed above the cooler (12) to form a cooler room (14).
[0015]
In addition, a freezing cooler (15) and a freezing fan (16) are installed at the back of the freezing room (7) also in the freezing spaces such as the temperature switching room (6), the ice making room, and the freezing room (7). The cool air from the discharge duct is guided to a cool air outlet to control the temperature switching room (6), the ice making room, and the freezing room (7) to be cooled to a predetermined set temperature.
[0016]
As shown in detail in FIG. 2, the cool air cooled by the refrigerator cooler (12) is discharged to an upper refrigerator compartment rear duct (17) by a fan (13) installed at an upper part, and The cool air from the duct (17) is blown into the refrigerator compartment (2) from the cool air outlets (18) formed at a plurality of locations above and below the duct surface, and circulates in the room to cool the storage items.
[0017]
The front surfaces of the refrigerator cooler (12) and the fan (13) are covered with a cooler cover (19) forming a rear wall of the vegetable room (5), and the vegetable room of the cooler cover (19). On the (5) side, there is disposed a cool air duct (20) having a cool air circulation gap extending in the width direction at the top and bottom, and returning the cool air from the rear bottom of the refrigerator compartment (2) into the duct (20). It is introduced and allowed to flow down, and is sucked from below into the cooler chamber (14) to be cooled again and circulated.
[0018]
The cold air duct (20) is formed of a molded aluminum sheet, and its upper edge extends to the vicinity of the front opening to partition the refrigerator compartment (2) from the vegetable compartment (5). ), And the lower end of the duct comes into contact with a drain gutter (21) that receives defrosted water from a cooler (12) disposed below the cooler chamber (14) and discharges the water outside the refrigerator. Let me.
[0019]
Therefore, the cold air from the refrigerator compartment (2) does not flow into the vegetable compartment (5), and the vegetable compartment (5) is indirectly connected to the partition plate (4) from the refrigerator compartment and the surface of the cold air duct (20). When the vegetable compartment door (8) is closed, it is kept closed to prevent water from flowing out of the air, and the interior is kept in a high humidity environment to dry vegetables and the like. And freshness can be maintained for a long period of time. At the same time, the amount of air for cooling can be reduced by not flowing cool air into the vegetable compartment (5), so that the number of revolutions of the fan (13) and the motor input can be reduced, and a power saving effect can be obtained.
[0020]
Further, since the cold air duct (20) and the upper partition plate (4) are formed of a thin plate of aluminum which is a good heat conductor, the bottom of the cold room (2) having a lower temperature and the cool air flow are formed. The inside of the vegetable compartment (5) can be cooled uniformly to an appropriate temperature, for example, about 4 ° C., efficiently from the upper surface and the rear surface under the influence of the radiant cooling of the cold air duct (20) which is at a low temperature. is there.
[0021]
A cooler cover (19) that covers the front of the refrigerator cooler (12) faces the vegetable compartment (5), which is conventionally a cooler cooler room (12) and a relatively hot vegetable compartment (5). In order to prevent the surface of the cover (19) from being dewed due to a temperature difference from the above, a heat insulating layer of a molded body (60) such as styrene foam is provided on the side of the cooler (12). Since the cool air duct (20) is provided on the surface of the cooler cover (19) on the side of the vegetable compartment (5) without using the cool air, the cool air always flows on the surface of the cooler cover (19) and evaporates. Prevents condensation due to action.
[0022]
Further, even if dew condensation occurs when the temperature difference with the cooler (12) becomes large and drops, the lower end of the cool air duct (20) communicates with the drain gutter (21), so that the dew water is There is no problem because it flows down from the duct to the drain gutter (21) and is drained out of the refrigerator, and the appearance is not impaired by condensation.
[0023]
Therefore, according to the above configuration, the lid cover (51) for covering the upper surface of the storage case (10) and preventing the inside of the case from being dried, which is conventionally required, is not required, and the cooler cover (19) and the cooling device are not required. Since high humidity can be maintained and dew condensation can be prevented without disposing the molded heat insulating material (60) between the vessels (12), the number of parts can be reduced and the configuration can be simplified.
[0024]
Conventionally, a temperature sensor for detecting the temperature of the refrigerator compartment is provided in the refrigerator compartment. However, in the present embodiment, the temperature sensor (22) is provided inside the cool air duct (20) on the front surface of the cooler cover (19). ) Was installed. This makes it possible to accurately detect the temperature of the returning cold air from the refrigerator compartment (2) without being affected by the outside air temperature or the temperature of the stored goods.
[0025]
In the above embodiment, the partition plate (4) for the cold air duct (20) on the back of the vegetable compartment (5) and the refrigerator compartment (2) forming the ceiling of the vegetable compartment was formed of an aluminum thin plate. If a cooling power for cooling to a predetermined temperature can be obtained, a molded product made of a synthetic resin plate or the like may be used instead of the aluminum thin plate, or only a part may be formed of a good heat conductor.
[0026]
【The invention's effect】
The present invention is configured as described above, and the in-room cooling by the cool air duct can cool the stored items in the vegetable room well, and keeps the humidity in the vegetable room high to maintain the freshness of the stored items for a long time. be able to. Furthermore, since the structure can be simplified, the number of parts can be reduced, thereby reducing cost reduction. Further, power consumption can be reduced by efficient cooling.
