Description

本発明は冷蔵庫、特にその冷蔵庫の野菜室における野菜の冷却保存構成に関するものである。   TECHNICAL FIELD The present invention relates to a refrigerator, and more particularly to a configuration for cooling and storing vegetables in a vegetable room of the refrigerator.
一般に家庭用冷蔵庫は、冷蔵庫本体内に温度帯域の異なる複数の貯蔵室、例えば、冷蔵室、野菜室、冷凍室を設けて構成してある。そして、上記冷蔵室、野菜室、冷凍室のレイアウトはユーザの使用実態に合わせ大きく二分されており、その一つはユーザが最も使用しやすい冷蔵庫本体の上下略中央部分に冷凍室を配置するタイプであり、もう一つは同部分に野菜室を配置するタイプである。   In general, a home refrigerator is configured such that a plurality of storage rooms having different temperature bands, for example, a refrigerator room, a vegetable room, and a freezer room are provided in a refrigerator main body. The layout of the refrigerator compartment, the vegetable compartment, and the freezer compartment is largely divided into two sections according to the actual use of the user. The other is a type where a vegetable room is arranged in the same part.
前記冷蔵庫本体の上下略中央部分に冷凍室を配置するタイプの冷蔵庫は今日の冷蔵庫の主流となってきており、生活スタイルの変化に伴って冷凍食品を多用するユーザにとって使い勝手の良いものとなっていて、数多くのものが提案されている(例えば、特許文献1参照)。   Refrigerators of the type in which a freezing room is arranged in the upper and lower substantially central portions of the refrigerator main body have become the mainstream of today's refrigerators, and have become convenient for users who frequently use frozen foods with changes in lifestyle. There are many proposals (for example, see Patent Document 1).
図26は特許文献1記載の冷蔵庫を示し、冷蔵庫本体100の上部に冷蔵室101、下部に野菜室102を設け、これら両室の間となる冷蔵庫本体100の上下略中央部分に冷凍室103が配置してある。そしてこの冷蔵庫は冷蔵庫本体100の野菜室102と冷凍室103とにまたがってその背面に冷却室104を設け、この冷却室104に冷却器105と冷却ファン106を配置して、当該冷却器105で生成した冷気を前記冷却ファン106により冷蔵室101、野菜室103、冷凍室102に供給し循環させ、これら各室に貯蔵されている食品を冷却保存するようになっている。   FIG. 26 shows a refrigerator described in Patent Document 1, in which a refrigerator compartment 101 is provided at an upper portion of a refrigerator main body 100 and a vegetable compartment 102 is provided at a lower portion, and a freezing compartment 103 is provided at a substantially central portion between the upper and lower sides of the refrigerator main body 100. It is arranged. In this refrigerator, a cooling room 104 is provided on the back of the refrigerator body 100 over a vegetable room 102 and a freezing room 103, and a cooler 105 and a cooling fan 106 are arranged in the cooling room 104. The generated cool air is supplied and circulated by the cooling fan 106 to the refrigerating room 101, the vegetable room 103, and the freezing room 102, and the food stored in each of these rooms is cooled and stored.
また、冷蔵庫本体の上下略中央部分に野菜室を配置するタイプの冷蔵庫は真ん中野菜冷蔵庫と略称され、野菜等の出し入れを中心に使用されるユーザに使い勝手が良いとして提案されている(例えば、特許文献1参照)。   Further, a refrigerator of a type in which a vegetable compartment is arranged at substantially the upper and lower central portions of the refrigerator body is abbreviated as a middle vegetable refrigerator, and has been proposed as being convenient for a user mainly used for putting in and out vegetables and the like (for example, see Patent Reference 1).
図27は特許文献2に記載されている冷蔵庫を示し、冷蔵庫本体200の上部に冷蔵室201、下部に冷凍室202を設け、これら両室の間となる冷蔵庫本200の上下略中央部分に野菜室203が配置してある。そしてこの冷蔵庫も前記と同様、冷蔵庫本体200の冷凍室202と野菜室203とにまたがってその背面に冷却室204を設け、この冷却室204に冷却器205と冷却ファン206を配置して、当該冷却器205で生成した冷気を前記冷却ファン206により冷蔵室201、野菜室203、冷凍室202に供給し循環させ、これら各室に貯蔵されている食品を冷却保存するようになっている。   FIG. 27 shows a refrigerator described in Patent Literature 2, in which a refrigerator compartment 201 is provided at an upper portion of a refrigerator main body 200 and a freezing compartment 202 is provided at a lower portion. A chamber 203 is arranged. In the same manner as described above, this refrigerator is also provided with a cooling chamber 204 on the back thereof over the freezing chamber 202 and the vegetable chamber 203 of the refrigerator main body 200, and a cooler 205 and a cooling fan 206 are arranged in the cooling chamber 204. The cool air generated by the cooler 205 is supplied and circulated by the cooling fan 206 to the refrigerating room 201, the vegetable room 203, and the freezing room 202, and the food stored in each of these rooms is cooled and stored.
上記いずれのタイプの冷蔵庫も、冷却室で生成した冷気は冷蔵室経由で野菜室に循環させ、この循環冷気によって野菜室内に収納した野菜を冷却保存している。   In any of the above types of refrigerators, the cool air generated in the cooling room is circulated to the vegetable room through the refrigerator room, and the vegetables stored in the vegetable room are cooled and stored by the circulating cool air.

しかしながら、上記従来の特許文献1、特許文献2記載のいずれの冷蔵庫も、野菜の冷却保存中に野菜室103,203で結露が生じることがあり、そのような場合この中に収納している野菜を劣化させてしまうという課題があった。   However, the refrigerators described in the above-mentioned conventional patent documents 1 and 2 may cause dew condensation in the vegetable compartments 103 and 203 during the cooling and preservation of the vegetables. There was a problem that it deteriorated.
すなわち、野菜室103,203はその背面に位置する冷却室104,204から冷輻射を受け、この冷輻射のため野菜室103,203の背面付近の温度が低温化しやすく、そのためこの部分で結露が生じるのであった。特に野菜室103,203は前記した如く冷蔵室101,201を冷却した後の比較的温度の高い冷気が供給されており、このような状況下において前記野菜室103,203は、当該野菜室103,203の背部に設けてある冷却室104,204から強い冷輻射を受け続けるため当該部分、すなわち、冷却室104,204と対向する背面部分の温度が低下し、野菜室内の冷気温度との間に大きな温度差が生じて、野菜室103,203に設けてある野菜収納ケースの背面部付近に結露が生じるのである。   That is, the vegetable compartments 103, 203 receive cold radiation from the cooling compartments 104, 204 located on the back side thereof, and the temperature near the rear faces of the vegetable compartments 103, 203 tends to be lowered due to the cold radiation, so that dew condensation occurs in this portion. It happened. Particularly, the vegetable compartments 103 and 203 are supplied with cold air having a relatively high temperature after cooling the refrigerator compartments 101 and 201 as described above. , 203 continue to receive strong cold radiation from the cooling chambers 104, 204 provided at the back, the temperature of the corresponding portion, that is, the temperature of the rear portion facing the cooling chambers 104, 204 decreases, and the temperature decreases between the cold room temperature in the vegetable room. Causes a large temperature difference, and dew condensation occurs near the back of the vegetable storage case provided in the vegetable compartments 103 and 203.
この結露は、通常の使用では生じないように前記冷却室104,204からの冷輻射を抑制する断熱構成としてあるが、野菜室103,203に多くの野菜或いはキャベツ等の大きな野菜等が一時的に収納された時にはこの野菜が持つ熱によって野菜近傍の温度が上昇し、前記冷却室104,204からの冷輻射によってどうしても温度差が大きくなって野菜室内の冷気が野菜収納ケースの壁面等に結露し始めるのであった。特に最近の冷蔵庫では、野菜収納ケースに飲料水やお茶、ジュース類の大型のペットボトルやパックも収納するようになってきており、しかも、そのペットボトル等は野菜に比べ常温であることが多いうえに熱容量が大きいため、野菜室103,203に収納された際、その収納直後から野菜及びペットボトル等近傍の温度が上昇し始めて前記冷却室104,204からの冷輻射に伴う温度差が大きくなりやすく、野菜室内冷気の結露による野菜劣化問題が顕在化する傾向にある。   This dew condensation has a heat insulation structure that suppresses the cold radiation from the cooling chambers 104 and 204 so as not to occur in normal use. However, many vegetables or large vegetables such as cabbage are temporarily stored in the vegetable chambers 103 and 203. When stored in the vegetable compartment, the temperature near the vegetable rises due to the heat of the vegetable, and the temperature difference inevitably increases due to the cold radiation from the cooling chambers 104 and 204, and the cool air in the vegetable compartment is condensed on the wall surface of the vegetable storage case and the like. I started to do it. Especially in recent refrigerators, large-sized plastic bottles and packs of drinking water, tea, and juice have been stored in vegetable storage cases, and the plastic bottles are often at room temperature compared to vegetables. In addition, since the heat capacity is large, when stored in the vegetable compartments 103 and 203, the temperature near the vegetables and plastic bottles and the like starts to rise immediately after the storage, and the temperature difference accompanying the cold radiation from the cooling chambers 104 and 204 is large. This tends to cause the vegetable deterioration problem due to condensation of cold air inside the vegetable room.
そしてこのような問題は特に真ん中野菜と略称される冷蔵庫において生じやすい傾向があり問題化しやすかった。これは真ん中野菜タイプの冷蔵庫はその野菜室203の底面がその下方に位置する冷凍室202からも冷輻射を受けるため、この冷凍室202からの冷輻射も加わってこれら両者の相乗作用により野菜室203の背面下部近傍が低温化しやすいからであり、冷却室204が野菜室背面部分にまで位置することになる大型の冷蔵庫においては避けがたいことであった。   Such a problem tends to occur particularly in refrigerators, which are abbreviated as middle vegetables. This is because the refrigerator of the middle vegetable type receives cold radiation from the freezing compartment 202 in which the bottom of the vegetable compartment 203 is located below, so that the cold radiation from the freezing compartment 202 is added and the vegetable compartment is synergized by these two. This is because the temperature in the vicinity of the lower rear portion of the 203 is easily lowered, and it is inevitable in a large refrigerator in which the cooling chamber 204 is located at the rear portion of the vegetable compartment.
また、上記結露問題は、購入してきた野菜及びペットボトル等の飲料水やお茶、ジュース類の温度が比較的高くなりがちな夏場において生じやすく、その結果、この場合は野菜室全体の温度が高目になりがちで、結露水も多くなるとともに、野菜室温度が高めとなることも加わって野菜やペットボトル等を十分冷却保存できなくなり、野菜の劣化が早まると同時に、ユーザに対し冷蔵庫が冷えないという印象を与えてしまい、冷蔵庫に対する信頼性を低下させてしまうという恐れもあった。   In addition, the above-mentioned dew condensation problem is likely to occur in summer when the temperature of purchased vegetables, drinking water such as plastic bottles, tea, and juice tends to be relatively high. As a result, in this case, the temperature of the whole vegetable room is high. As it tends to be noticeable, the amount of dew condensation increases, and the temperature of the vegetable room increases, so that the vegetables and plastic bottles cannot be cooled and stored sufficiently. There was a fear that it would give the impression that there was no refrigerator, and would reduce the reliability of the refrigerator.
このような問題を解決する手法の一つとして特開平11−118314号公報に開示されているように冷却室を冷凍室の背面のみに設けて野菜室の背面部分には位置させないようにすることが考えられる。しかしながら、このような構成にすると、冷却室に設ける冷却器の大きさが限定されて冷却能力に制約が生じ、大能力の大型冷蔵庫には応用できず、よって大型冷蔵庫では冷却室からの冷輻射で生じる結露による野菜劣化問題を解消することができないことになる。   As one method for solving such a problem, as disclosed in Japanese Patent Application Laid-Open No. H11-118314, a cooling room is provided only on the back of the freezing room and is not located on the back of the vegetable room. Can be considered. However, with such a configuration, the size of the cooler provided in the cooling chamber is limited, and the cooling capacity is limited, so that the cooling capacity cannot be applied to a large-capacity large refrigerator. The problem of vegetable deterioration due to condensation caused by the condensation cannot be solved.
本発明は、野菜室内で野菜等を良好に冷却保存できる冷蔵庫を提供することを目的としたものである。
The present invention is intended to provide a refrigerator capable of satisfactorily cooling store vegetables and the like with vegetables compartment.
本発明の冷蔵庫は、野菜室と、蔵室と、冷気を生成する冷却器を有する冷却室と、前記野菜室の背後に設けられている、前記冷蔵室の冷気を前記冷却室に戻すための戻り通路と、前記野菜室の天面に設けられている冷気通路であって、前記野菜室の背面で前記戻り通路に連通し、かつ、前記野菜室の内部に冷気を供給するための吹出口が前記野菜室の正面側に設けられている冷気通路と、前記野菜室の背面に設けられている、前記野菜室の冷気を前記戻り通路に戻す戻り口と、前記冷気通路に設けられている、前記戻り通路から冷気を吸引して吸引した冷気を前記吹出口に送る野菜室ファンとを備えることを特徴とする。 Refrigerator of the present invention, a vegetable compartment, a refrigerated chamber, a cooling chamber having a cooler for generating cold air is provided behind the vegetable compartment, the cool air of the cooling chamber for returning the cooling chamber A return passage, and a cool air passage provided on the top surface of the vegetable compartment, wherein the blower communicates with the return passage at the back of the vegetable compartment and supplies cool air to the interior of the vegetable compartment.

第1の発明は、冷蔵室、野菜室、冷凍室を備え、前記冷凍室および野菜室の背面に冷気生成用の冷却器と冷却器で生成した冷気を前記冷蔵室、野菜室、冷凍室に供給循環させる冷却ファン等とを具備する冷却室を備えた冷蔵庫であって、前記冷蔵室、冷凍室、野菜室に冷気を循環させる前記冷却ファンとは別にさらに前記野菜室に野菜室ファンを設け、かつ前記野菜室の背面に前記冷却ファンによって循環される冷気戻り通路を設けるとともに、この冷気戻り通路と野菜室との間であって、前記野菜室の野菜ファン吸引側と排気側に前記冷気戻り通路と連通する野菜冷気入口および野菜冷気戻り口を設けた構成としてある。   The first invention includes a refrigerator room, a vegetable room, and a freezer room, and a cooler for generating cool air and a cool air generated by the cooler are provided on the back of the refrigerator room and the vegetable room to the refrigerator room, the vegetable room, and the freezer room. A refrigerator provided with a cooling room having a cooling fan and the like for supplying and circulating, wherein the refrigerator room, the freezing room, and a vegetable room fan are further provided in the vegetable room separately from the cooling fan for circulating cool air in the vegetable room. And a cool air return passage circulated by the cooling fan at the back of the vegetable compartment, and the cool air return passage between the cool air return passage and the vegetable compartment, on the vegetable fan suction side and the exhaust side of the vegetable compartment. A vegetable cold air inlet and a vegetable cold air return port communicating with the return passage are provided.
これにより、この冷蔵庫では野菜室ファンを回転させることにより冷気戻り通路から野菜室内に冷気を取り入れこれを野菜室内で拡散または及び循環させて、冷却室からの冷輻射を受ける部分に大きな温度差が生じるのを抑制し、冷却室からの冷輻射に起因する結露発生を防止することができるとともに、冷気生成用の冷却器を大型化して冷却室が冷凍室と野菜室にまたがる大きな大能力の大型冷蔵庫になってもその冷却室からの冷輻射に起因する結露を抑制することができる。よって、小能力の小型冷蔵庫から大能力の大型冷蔵庫に至る全域の冷蔵庫において、その冷却室からの冷輻射で生じる結露水による野菜劣化を抑制し、より良好な状態で野菜を冷却保存することが可能となる。   Thus, in this refrigerator, by rotating the vegetable room fan, the cool air is taken into the vegetable room from the cool air return passage and diffused or circulated in the vegetable room, so that a large temperature difference occurs in the portion receiving the cold radiation from the cooling room. This can prevent the occurrence of dew condensation due to cold radiation from the cooling room, and also increase the size of the cooler for generating cold air, and the large capacity of the cooling room spans the freezing room and the vegetable room. Even if it becomes a refrigerator, it is possible to suppress dew condensation caused by cold radiation from the cooling chamber. Therefore, in refrigerators ranging from small-sized small refrigerators to large-sized large refrigerators, it is possible to suppress vegetable deterioration due to dew condensation water generated by cold radiation from the cooling room and cool and preserve vegetables in a better condition. It becomes possible.
第2の発明は、第1の発明において、野菜室ファンと野菜冷気入口は野菜室の背面下部に配置するとともに、前記野菜室の上部には野菜冷気戻り口と連通する野菜冷気吸込み口を設けた構成としてある。   According to a second aspect of the present invention, in the first aspect, the vegetable room fan and the vegetable cold air inlet are disposed at a lower rear portion of the vegetable room, and a vegetable cold air inlet is provided at the upper portion of the vegetable room to communicate with the vegetable cold air return port. There is a configuration.
これにより、野菜室ファンは野菜室内に冷気を安定的かつ効率よく取り込んで同野菜室内で拡散または循環させることができるから、結露発生をより確実に抑制し良好な状態で野菜を冷却保存することが可能となる。   This allows the vegetable room fan to stably and efficiently take in cool air into the vegetable room and diffuse or circulate it in the vegetable room, so that dew condensation is more reliably suppressed and vegetables are cooled and stored in good condition. Becomes possible.
第3の発明は、第1の発明において、野菜室ファンと野菜冷気入口とは野菜室の天井部に配置するとともに、野菜室ファンは野菜室上部に吹き出し口を開口させ、かつ、野菜冷気戻り口を野菜室の下部に設けた構成としてある。   According to a third invention, in the first invention, the vegetable room fan and the vegetable cold air inlet are arranged on the ceiling of the vegetable room, and the vegetable room fan has an outlet opened at the upper part of the vegetable room, and the vegetable cold air returns. The mouth is located below the vegetable compartment.
これにより、前記第2の発明と同様、野菜室ファンは野菜室内に冷気を安定的かつ効率よく取り込んで同野菜室内で拡散または循環させることができるから、結露発生をより確実に抑制し良好な状態で野菜を冷却保存することが可能となる。   Thereby, similarly to the second aspect, the vegetable room fan can stably and efficiently take in the cool air into the vegetable room and diffuse or circulate the cool air in the vegetable room. The vegetables can be cooled and stored in the state.
第4の発明は、第3の発明において、野菜室は冷蔵室の下部に配置するとともに、野菜室ファンは野菜室と冷蔵室との間を仕切って野菜室の天井を構成する仕切板内に斜めに傾斜させて配置した構成としてある。   In a fourth aspect based on the third aspect, the vegetable compartment is arranged at a lower portion of the refrigerator compartment, and the vegetable compartment fan separates the vegetable compartment and the refrigerator compartment from each other into a partition plate constituting a ceiling of the vegetable compartment. It is configured to be arranged obliquely.
これにより、野菜室の冷却を効率の良いものとしつつ野菜室の容積も確保する形で野菜室ファンを野菜室内に設けることができる。すなわち、野菜室の上部に冷蔵室が位置しているので野菜室はこの冷蔵室からの冷輻射によって適度に冷却され、その結果、仕切板は断熱強化のための断熱材を組み込む必要がなくなるのでそのスペースを利用して野菜室ファンを組み込むことができ、しかも野菜室ファンは傾斜させて配置してあるから、野菜室ファンを組み込んでいるのにもかかわらず仕切板厚さを大きく増加させる必要がなくなり、その分野菜室の容積を大きく確保することができる。   Thereby, the vegetable room fan can be provided in the vegetable room in such a manner that the cooling of the vegetable room is made efficient and the volume of the vegetable room is secured. That is, since the refrigerator compartment is located at the top of the vegetable compartment, the vegetable compartment is appropriately cooled by the cold radiation from the refrigerator compartment, and as a result, the partition plate does not need to incorporate heat insulating material for heat insulation enhancement. The vegetable room fan can be installed using the space, and the vegetable room fan is arranged at an angle. Therefore, it is necessary to greatly increase the thickness of the partition plate despite incorporating the vegetable room fan. And the volume of the vegetable room can be increased accordingly.
第5の発明は、第1〜第4の発明において、野菜室ファンは野菜室に設けた野菜室温度検出手段の検出温度に基づいて制御する構成としてある。   In a fifth aspect based on the first to fourth aspects, the vegetable room fan is controlled based on a temperature detected by a vegetable room temperature detecting means provided in the vegetable room.
これにより、野菜室の温度が所定温度以上になれば野菜室ファンを駆動させて野菜室内の冷気を拡散または及び循環させることができるとともに、前記所定温度よりもさらに高い温度になれば野菜室ファンの回転数を上げて冷気の拡散または及び循環量を増強し、更には新鮮な低温冷気を取り込み混入させるタイプではその混入量を増加させることもできて野菜室を確実に冷却することができ、夏場における冷却不足を解消し野菜等の良好な冷却保存を確実に実現して冷蔵庫の信頼性を高めることができる。   Thereby, the vegetable room fan can be driven to diffuse or circulate the cool air in the vegetable room when the temperature of the vegetable room becomes equal to or higher than the predetermined temperature, and the vegetable room fan can be circulated when the temperature becomes higher than the predetermined temperature. By increasing the number of rotations to increase the amount of diffusion or circulation of cold air, furthermore, in the type that takes in and mixes fresh low-temperature cold air, the mixing amount can also be increased and the vegetable room can be cooled reliably, Insufficiency of cooling in summer can be eliminated, and good cooling and preservation of vegetables and the like can be reliably realized, and the reliability of the refrigerator can be improved.
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。尚、この実施の形態ではいわゆる真ん中野菜と略称されるタイプの冷蔵庫を例にして説明するが、これによって、本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. In addition, in this embodiment, a refrigerator of a type abbreviated as a so-called middle vegetable will be described as an example, but the present invention is not limited thereto.

次にこの冷蔵庫の制御構成について説明する。   Next, a control configuration of the refrigerator will be described.
<制御構成>
図23は本実施の形態の冷蔵庫における制御ブロック図を示し、65は冷蔵室温度検知手段、66は野菜室温度検知手段、67は冷凍室温度検知手段で、いずれもサーミスタで形成してあり、それぞれ冷蔵室7、野菜室8、冷凍室9の適所に設置されている。68は冷蔵庫全体を統括制御する制御部で、マイクロコンピュータ等によって構成してあり、前記冷蔵室温度検知手段65、冷凍室温度検知手段67からの出力に基づきあらかじめ組み込まれた制御ソフトにしたがって冷蔵室ダンパ31、冷凍室ダンパ34を開閉制御するとともに、圧縮機15、冷却ファン19及び必要に応じて第一、第二のヒータ23、56を駆動して各室を設定温度に制御する。さらにこの制御部68は冷蔵室温度検知手段65及び野菜室温度検知手段66からの出力に基づき野菜室8の野菜室通路部50に組み込んだ野菜室ファン53の運転を制御するようになっている。具体的には冷蔵室温度検知手段65及び野菜室温度検知手段66が検出する温度がそれぞれの設定温度よりも高い温度をいずれか一方が検知すると野菜室ファン53を駆動するようになっている。
<Control configuration>
FIG. 23 shows a control block diagram of the refrigerator of the present embodiment, wherein 65 is a refrigerator room temperature detecting means, 66 is a vegetable room temperature detecting means, 67 is a freezing room temperature detecting means, and both are formed by thermistors. The refrigerator room 7, the vegetable room 8, and the freezer room 9 are installed at appropriate places, respectively. Reference numeral 68 denotes a control unit for integrally controlling the whole refrigerator, which is constituted by a microcomputer or the like. The control unit 68 is based on the output from the refrigerator temperature detecting means 65 and the freezing room temperature detecting means 67, and according to control software pre-installed therein. Opening / closing control of the damper 31 and the freezing room damper 34 is performed, and the compressor 15, the cooling fan 19 and, if necessary, the first and second heaters 23 and 56 are driven to control each chamber to a set temperature. Further, the controller 68 controls the operation of the vegetable room fan 53 incorporated in the vegetable room passage section 50 of the vegetable room 8 based on the outputs from the refrigerator room temperature detecting means 65 and the vegetable room temperature detecting means 66. . Specifically, the vegetable room fan 53 is driven when one of the temperatures detected by the refrigerator room temperature detecting means 65 and the vegetable room temperature detecting means 66 is higher than the set temperature.
さらにまた、冷蔵室温度検知手段65及び野菜室温度検知手段66が検出する温度が常に低く、一定時間以上連続して冷蔵室ダンパ31が開かないときにも野菜室ファン53を駆動するようになっている。   Furthermore, the temperature of the refrigerator compartment temperature detecting means 65 and the temperature detected by the vegetable compartment temperature detecting means 66 are always low, and the vegetable compartment fan 53 is driven even when the refrigerator compartment damper 31 is not opened for a certain period of time or more. ing.
以上のように構成された冷蔵庫について、以下その動作、作用を説明する。   The operation and operation of the refrigerator configured as described above will be described below.
まず、冷凍サイクルの動作について説明する。   First, the operation of the refrigeration cycle will be described.
庫内の設定された温度に応じて制御部68からの信号により冷凍サイクルが動作し冷却運転が行われる。圧縮機15の動作により吐出された高温高圧の冷媒は、凝縮器(図示せず)である程度凝縮液化し、さらに冷蔵庫の側面や背面、また冷蔵庫の前面間口に配設された冷媒配管(図示せず)などを経由し冷蔵庫の結露を防止しながら凝縮液化し、キャピラリーチューブ(図示せず)に至る。その後、キャピラリーチューブでは圧縮機15への吸入管(図示せず)と熱交換しながら減圧されて低温低圧の液冷媒となって冷却室の冷却器18に至る。   The refrigeration cycle is operated by a signal from the control unit 68 according to the temperature set in the refrigerator, and the cooling operation is performed. The high-temperature and high-pressure refrigerant discharged by the operation of the compressor 15 is condensed and liquefied to some extent in a condenser (not shown), and furthermore, refrigerant pipes (not shown) disposed on the side and rear surfaces of the refrigerator and on the front opening of the refrigerator. And condensed and liquefied while preventing dew condensation in the refrigerator, and reaches a capillary tube (not shown). Thereafter, in the capillary tube, the pressure is reduced while exchanging heat with a suction pipe (not shown) to the compressor 15 to become a low-temperature low-pressure liquid refrigerant, which reaches the cooler 18 in the cooling chamber.
ここで、前記冷却器18内の冷媒は蒸発気化し、当該冷却器18を有する冷却室16で各貯蔵室を冷却するための冷気が生成される。   Here, the refrigerant in the cooler 18 evaporates and evaporates, and cool air for cooling each storage room is generated in the cooling chamber 16 having the cooler 18.
次に冷気循環による冷却動作について説明する。   Next, the cooling operation by the cool air circulation will be described.
冷却室16内で生成された低温の冷気は、冷却ファン19によって、冷却室冷気搬送路30から冷蔵室7と冷凍室9に送られ、冷蔵室7に供給された冷気は冷蔵室7を冷却した後、野菜室8に供給され、それぞれの室が設定温度に冷却される。そして、各室を冷却したのちの冷気は、再び冷却室16に戻って冷却器18により冷却され、冷却ファン19で各室に循環していく。また、上記各室への冷気供給は、制御部68が冷蔵室温度検知手段65及び冷凍室温度検知手段67の検出温度に基づき圧縮機15と冷却ファン19を運転/停止、及び冷蔵室ダンパ31、冷凍室ダンパ34を開・閉制御し、それぞれの室が設定温度帯に維持されるようになっている。   The low-temperature cold air generated in the cooling room 16 is sent from the cooling room cool air conveyance path 30 to the refrigerator room 7 and the freezing room 9 by the cooling fan 19, and the cool air supplied to the refrigerator room 7 cools the refrigerator room 7. After that, it is supplied to the vegetable room 8 and each room is cooled to the set temperature. Then, the cool air after cooling each chamber returns to the cooling chamber 16 again, is cooled by the cooler 18, and is circulated to each chamber by the cooling fan 19. In addition, the controller 68 controls the operation of the compressor 15 and the cooling fan 19 based on the temperatures detected by the refrigerator temperature detecting means 65 and the freezing room temperature detecting means 67, and supplies the cold air to each chamber. The freezer compartment damper 34 is controlled to open and close so that each compartment is maintained at a set temperature zone.
次に、本発明の特徴となる野菜室8の冷却動作について詳しく説明する。   Next, the cooling operation of the vegetable compartment 8 which is a feature of the present invention will be described in detail.
野菜室8は冷蔵冷気戻り通路33からの冷蔵室冷却後の冷気が図12に示すように冷気の戻り通路38に設けられている野菜冷気入口44から流れ込み冷却される。   As shown in FIG. 12, the vegetable room 8 is cooled by flowing cool air from the cool room return passage 33 through the cool vegetable inlet 44 provided in the cool air return passage 38 as shown in FIG.
ここで、この冷蔵庫では図12で示すように野菜室8内に野菜室ファン53が設けられているから、野菜室ファン53の回転によって、前記野菜冷気入口44から野菜室8内に多くの冷気を吸引し、野菜室ファン53の吹出口54より野菜室8内の下段野菜収納ケース49a後面に向かって供給されることになる。   Here, in this refrigerator, as shown in FIG. 12, a vegetable compartment fan 53 is provided in the vegetable compartment 8, so that the rotation of the vegetable compartment fan 53 causes a large amount of cold air to enter the vegetable compartment 8 from the vegetable cold air inlet 44. Is supplied from the outlet 54 of the vegetable compartment fan 53 toward the rear surface of the lower vegetable storage case 49a in the vegetable compartment 8.
野菜室8の下段野菜収納ケース49aに向かって供給された冷気は、図12の実線矢印で示すように野菜収納ケース48と野菜室8の底面及び内周壁との間の空間を流れ、大部分の冷気は第一の野菜冷気吸込み口47、第二の野菜冷気吸込み口51から第一の通路47a、第二の通路51aを介して野菜冷気戻り口46より戻り通路38へと流出するとともに、他の一部の冷気は破線矢印で示すように野菜室8内を拡散または及び循環する。   The cold air supplied toward the lower vegetable storage case 49a of the vegetable room 8 flows through the space between the vegetable storage case 48 and the bottom surface and the inner peripheral wall of the vegetable room 8 as indicated by solid arrows in FIG. The cold air flows out of the first vegetable cold air inlet 47 and the second vegetable cold air inlet 51 through the first passage 47a and the second passage 51a to the return passage 38 from the vegetable cold air return port 46, The other part of the cool air diffuses or circulates in the vegetable compartment 8 as shown by the dashed arrow.
一方、全ての貯蔵室が設定温度を下回り圧縮機15及び冷却ファン19の動作が停止した状態で野菜室ファン53が回転すると、全ての冷気は流れが停止し、冷気の戻り通路38での冷気の流れがなくなる。この場合、第一の野菜冷気吸込み口47、第二の野菜冷気吸込み口51及び第一の通路47a、第二の通路51aの通気抵抗が野菜室8内の通気抵抗に比べて大きいため、野菜室ファン53は、図13の実線矢印で示すように野菜室8内で冷気のすべてを拡散およびまたは循環させるようになる。   On the other hand, when the vegetable compartment fan 53 rotates in a state where the operation of the compressor 15 and the cooling fan 19 is stopped when all the storage rooms are below the set temperature, all the cool air stops flowing, and the cool air in the cool air return passage 38 is cooled. Flow disappears. In this case, since the ventilation resistance of the first vegetable cold air suction port 47, the second vegetable cold air suction port 51, the first passage 47a, and the second passage 51a is larger than the ventilation resistance in the vegetable compartment 8, the vegetables are cooled. The room fan 53 diffuses and / or circulates all of the cool air in the vegetable room 8 as shown by the solid line arrow in FIG.
この野菜室ファン53によって拡散または及び循環する冷気は、野菜室8の背面に位置する冷却室16からの冷輻射および下方に位置する冷凍室9からの冷輻射によって低温化しやすい野菜室背面下部付近の温度を野菜室8内に拡散させ、野菜室8内の温度を下げてより効果的に野菜室8内を冷却すると同時に、野菜室背面下部付近に極端な低温化や温度差が生じるのを防止し、この冷却室16や冷凍室9からの冷輻射が原因となる結露発生を抑制する。   The cool air diffused or circulated by the vegetable room fan 53 is in the vicinity of the lower portion of the rear of the vegetable room which is likely to be cooled by the cold radiation from the cooling room 16 located on the back of the vegetable room 8 and the cold radiation from the freezing room 9 located below. Is diffused into the vegetable compartment 8, and the temperature in the vegetable compartment 8 is lowered to cool the vegetable compartment 8 more effectively. This prevents the occurrence of dew condensation caused by the cold radiation from the cooling chamber 16 and the freezing chamber 9.
以上のようにしてこの冷蔵庫は冷却運転中と冷却停止中の何れの場合でも野菜室8の局部的な低温化による結露発生を防止するから、冷気生成用の冷却器18を大型化して冷却室16が冷凍室9と野菜室8にまたがる大きな大能力の大型冷蔵庫であっても、その冷却室16からの冷輻射に起因する結露を抑制することができる。したがって、小能力の小型冷蔵庫から大能力の大型冷蔵庫に至る全域の冷蔵庫において、その冷却室16からの冷輻射で生じる結露水による野菜劣化を抑制し、良好な状態で野菜を冷却保存することが可能となる。   As described above, this refrigerator prevents the occurrence of dew condensation due to the local lowering of the temperature of the vegetable room 8 in both the cooling operation and the cooling stop. Even if 16 is a large-sized refrigerator having a large capacity that spans the freezing room 9 and the vegetable room 8, it is possible to suppress dew condensation caused by cold radiation from the cooling room 16. Therefore, in refrigerators ranging from small-sized small refrigerators to large-sized large refrigerators, it is possible to suppress vegetable deterioration due to dew condensation water generated by cooling radiation from the cooling chamber 16 and cool and preserve vegetables in a good state. It becomes possible.
しかも、本実施の形態における冷蔵庫は、野菜室8を冷蔵室7と冷凍室9との間となる冷蔵庫本体1上下略中央部分に設けた真ん中野菜室タイプの冷蔵庫となっているから、前記した如く結露発生を防止して野菜を良好な状態に冷却保存しつつ、野菜等の出し入れを中心に使用されるユーザの使い勝手を高めることができ、効果的である。   In addition, the refrigerator in the present embodiment is a middle vegetable room type refrigerator in which the vegetable compartment 8 is provided at approximately the upper and lower central portions of the refrigerator main body 1 between the refrigerator compartment 7 and the freezer compartment 9. As described above, it is possible to prevent the occurrence of dew condensation and cool and preserve the vegetables in a good state, and to enhance the usability of a user mainly used for taking in and out vegetables and the like, which is effective.
加えて、前記野菜室ファン53は野菜冷気入口44の前方でかつ前から見て重なる位置に設けているため、野菜室ファン53の吸込み側の風路面積を大きくすることができ野菜室ファン53の風路抵抗を小さくすることができる。これにより、野菜室8内のより多くの冷気を拡散及び循環させることができるため、結露発生の抑制効果を更に高めることができる。   In addition, since the vegetable room fan 53 is provided in front of the vegetable cold air inlet 44 and at a position overlapping when viewed from the front, the area of the air passage on the suction side of the vegetable room fan 53 can be increased. Can reduce the wind path resistance. Thereby, more cold air in the vegetable compartment 8 can be diffused and circulated, so that the effect of suppressing the occurrence of dew condensation can be further enhanced.
また、上記野菜室ファン53は野菜収納ケース48の下段野菜収納ケース49a及び上段野菜収納ケース49bの外周に向けて冷気を拡散または及び循環させるから、野菜室ファン53によって拡散または及び循環する冷気が下段野菜収納ケース49a及び上段野菜収納ケース49b内に入って野菜同士の間を流れることを抑制でき、野菜同士の間を冷気が流れることによって生じがちな野菜の乾燥劣化も防止して新鮮かつ良好な状態で野菜を冷却保存することができる。   Further, the vegetable room fan 53 diffuses or circulates cold air toward the outer periphery of the lower vegetable storage case 49a and the upper vegetable storage case 49b of the vegetable storage case 48. It is possible to prevent the vegetables from entering the lower vegetable storage case 49a and the upper vegetable storage case 49b and flowing between the vegetables, and to prevent the drying and deterioration of the vegetables, which are likely to be caused by the cool air flowing between the vegetables, to be fresh and good. The vegetables can be stored in a cool condition.
特にこの実施の形態では上記下段野菜収納ケース49a及び上段野菜収納ケース49bで構成される野菜収納ケース48の上部に野菜室内を拡散または循環する冷気の吸込み口ともなる第一の野菜冷気吸込み口47及び第二の野菜冷気吸込み口51を設けているから、野菜室8内を拡散または及び循環する冷気は下段野菜収納ケース49a及び上段野菜収納ケース49bからなる野菜収納ケース48内に入り込むことなくそのまま第一の野菜冷気吸込み口47及び第二の野菜冷気吸込み口51へと流れる様になり、より確実に野菜の乾燥劣化を防止して新鮮かつ良好な状態で野菜を冷却保存することができる。この野菜の乾燥劣化防止効果は上段野菜収納ケース49bの上面開口縁を野菜室天井面ともなる仕切板5に近接させることでより高めることができるとともに、当該上面面開口を覆う蓋を設ければさらに効果的に高めることができる。   In particular, in this embodiment, the first vegetable cold air suction port 47 which also serves as a cold air suction port for diffusing or circulating in the vegetable compartment above the vegetable storage case 48 composed of the lower vegetable storage case 49a and the upper vegetable storage case 49b. And the second vegetable cool air suction port 51 is provided, so that the cool air diffusing or circulating in the vegetable compartment 8 does not enter into the vegetable storage case 48 composed of the lower vegetable storage case 49a and the upper vegetable storage case 49b. It flows to the first vegetable cold air suction port 47 and the second vegetable cold air suction port 51, so that drying and deterioration of vegetables can be prevented more reliably, and vegetables can be cooled and stored in a fresh and good state. The effect of preventing the drying and deterioration of the vegetables can be further enhanced by bringing the upper opening edge of the upper vegetable storage case 49b closer to the partition plate 5, which also serves as the ceiling of the vegetable compartment, and if a lid that covers the upper opening is provided. It can be more effectively increased.
加えて、上記野菜室ファン53は下段野菜収納ケース49a及び上段野菜収納ケース49bで構成される野菜収納ケース48の上部開口縁より下方部分に位置しているから、野菜室ファン53から送風される冷気は野菜収納ケース48のうち、特にその下段野菜収納ケース49aの底面及び下部外周付近を拡散または及び循環するようになる。したがって、この野菜室ファン53によって拡散または及び循環する冷気はさらに野菜収納ケース48内に入り込みにくいものとなり、野菜収納ケース48内に冷気が入り込んで循環することにより生じる野菜の乾燥劣化をこの点からも確実に防止することができ、より新鮮かつ良好な状態で野菜を冷却保存することができる。   In addition, since the vegetable room fan 53 is located below the upper opening edge of the vegetable storage case 48 composed of the lower vegetable storage case 49a and the upper vegetable storage case 49b, it is blown from the vegetable room fan 53. The cool air diffuses or circulates in the vicinity of the bottom surface and the lower periphery of the lower vegetable storage case 49a in the vegetable storage case 48. Therefore, the cool air diffused or circulated by the vegetable room fan 53 is further difficult to enter the vegetable storage case 48, and the drying and deterioration of the vegetables caused by the cool air entering and circulating in the vegetable storage case 48 is reduced from this point. Can be reliably prevented, and the vegetables can be cooled and stored in a fresher and better condition.
加えて、この実施の形態では上記野菜収納ケース48はその下段野菜収納ケース49aの内部を左右に仕切ってその一方にペットボトルやパック等の非野菜収納部59(以下、ペットボトル等収納部59と称す)を設け、このペットボトル等収納部59側の野菜室背面部分に野菜室ファン53を設けて、当該ペットボトル等収納部59に向けて野菜室内の冷気を拡散または及び循環させるように構成してあるから、野菜室ファン53からの冷気はペットボトル等収納部59の周りを集中的に循環するようになり、ペットボトル等収納部59に収納されているペットボトルやパック等を効率よく冷却することができる。特にペットボトル等収納部59に収納されているペットボトルやパック等の飲料水等は野菜よりも熱容量が大きくて冷えにくいことから効果的であり、これによってペットボトル等の収納による野菜室温度の上昇を効率よく抑制し、結露発生を効果的に防止すると同時に野菜の保存も良好に行うことができる。   In addition, in this embodiment, the vegetable storage case 48 partitions the inside of the lower vegetable storage case 49a left and right, and one of the non-vegetable storage portions 59 such as a plastic bottle or a pack (hereinafter referred to as a plastic bottle storage portion 59). A vegetable room fan 53 is provided on the back of the vegetable room on the side of the plastic bottle storage section 59 to diffuse or circulate cold air in the vegetable room toward the plastic bottle storage section 59. Since it is configured, the cool air from the vegetable room fan 53 intensively circulates around the storage section 59 such as a plastic bottle, so that the plastic bottles and packs stored in the storage section 59 such as the plastic bottle can be efficiently used. Can be cooled well. In particular, drinking water, such as a plastic bottle or a pack, stored in the plastic bottle storage section 59 is effective because it has a larger heat capacity and is harder to cool than vegetables. The rise can be suppressed efficiently, and the occurrence of dew condensation can be effectively prevented, and at the same time, the vegetables can be stored well.
特にこの実施の形態では、野菜室ファン53とともに野菜室8に設けた第一の野菜冷気吸込み口47をも野菜収納ケース48のペットボトル等収納部59側の部分に設けた構成としてあるから、野菜室ファン53からの冷気をペットボトル等収納部分にさらに効率よく集中的に循環させることができ、効果的である。   In particular, in this embodiment, the first vegetable cold air inlet 47 provided in the vegetable room 8 together with the vegetable room fan 53 is also provided in the portion of the vegetable storage case 48 on the side of the storage portion 59 such as a plastic bottle. The cool air from the vegetable room fan 53 can be efficiently and intensively circulated to the storage part such as a plastic bottle, which is effective.
また、野菜室8内の冷気を循環させるためのもう一つの吸込み口ともなる第二の野菜冷気吸込み口51を野菜室ファン53と略対角位置の野菜室上部に設けた構成としてあるから、野菜室ファン53からの冷気は野菜収納ケース48のペットボトル等収納部59の底面部分を通って前方へと野菜室8内を斜めに縦断しながら拡散または及び循環して野菜室上部の第二の野菜冷気吸込み口51へとm流れる様になるので、下段野菜収納ケース49a及び上段野菜収納ケース49bからなる野菜室ケース内への冷気の入り込みを防止しつつ下段野菜収納ケース49a及び上段野菜収納ケース49bからなる野菜ケースの外周に広範囲に冷気を拡散または及び循環させることができ、野菜及びペットボトル等を効果的に冷却することができる。   Also, since the second vegetable cold air suction port 51, which is another suction port for circulating the cool air in the vegetable compartment 8, is provided at the upper portion of the vegetable compartment substantially diagonally to the vegetable compartment fan 53, The cool air from the vegetable compartment fan 53 diffuses or circulates while diagonally traversing the inside of the vegetable compartment 8 to the front through the bottom portion of the plastic bottle or the like storage portion 59 of the vegetable storage case 48, and circulates through the second portion at the top of the vegetable compartment Flows into the vegetable cold air suction port 51 of the lower vegetable storage case 49a and the upper vegetable storage case 49b while preventing cold air from entering the vegetable room case composed of the lower vegetable storage case 49a and the upper vegetable storage case 49b. Cold air can be diffused or circulated widely over the outer periphery of the vegetable case composed of the case 49b, and the vegetables and plastic bottles can be effectively cooled.
また、この冷蔵庫は、冷蔵冷気往き通路32と冷蔵冷気戻り通路33との間に連通路39が形成してあり、野菜室ファン53が回転するとその吸引力によって冷蔵冷気往き通路32内の低温な新鮮冷気が冷蔵冷気戻り通路33内に直接混入して戻り通路38を介し野菜冷気入口44から野菜室8内に供給される。すなわち、野菜室8は、冷蔵室7からの冷蔵室冷却後の比較的温度が高くなっている戻り冷気によって冷却されるが、この冷蔵庫では野菜室ファン53の回転により前記冷蔵室冷却後の冷気に低温の新鮮冷気が混入して低温化された冷気で野菜室8を冷却することになる。   Further, in this refrigerator, a communication path 39 is formed between the refrigerated cool air passage 32 and the refrigerated cool air return passage 33, and when the vegetable room fan 53 rotates, the low temperature inside the refrigerated cool air passage 32 by the suction force. Fresh cool air is directly mixed into the refrigerated cool air return passage 33 and supplied to the vegetable compartment 8 from the vegetable cool air inlet 44 via the return passage 38. In other words, the vegetable compartment 8 is cooled by the return cold air having a relatively high temperature after the refrigerator compartment is cooled from the refrigerator compartment 7, and in this refrigerator, the rotation of the vegetable compartment fan 53 causes the cool air after the refrigerator compartment to cool. The vegetable room 8 is cooled by the low-temperature cold air mixed with the low-temperature fresh cold air.
したがって野菜室8を効果的に冷却することができ、例えば、野菜やペットボトル等が一時的に多く収納された時などのように冷却負荷条件が悪いときでも、野菜室8を確実に冷却することができる。また、上記連通路39を介して取り込む低温の新鮮冷気の量は野菜室ファン53の回転数を上げることによって増加させることができ、夏場で熱容量の大きい常温のペットボトル等が大量に収納された時でも、これを確実に冷却することができる。しかも野菜室8を確実に冷却できるので、冷却室16からの冷輻射による結露発生も効率よく抑制でき、野菜を良好な状態で冷却保存することができる。   Therefore, the vegetable room 8 can be effectively cooled, and the vegetable room 8 can be reliably cooled even when the cooling load condition is poor, for example, when many vegetables and plastic bottles are temporarily stored. be able to. Further, the amount of low-temperature fresh cool air taken in through the communication passage 39 can be increased by increasing the rotation speed of the vegetable room fan 53, and a large amount of room-temperature PET bottles and the like having a large heat capacity in summer are stored. Even at times, this can be reliably cooled. In addition, since the vegetable compartment 8 can be reliably cooled, the occurrence of dew condensation due to cold radiation from the cooling compartment 16 can be suppressed efficiently, and the vegetables can be cooled and stored in a favorable state.
また、上記野菜室ファン53は、冷蔵室温度検知手段65からの出力によって冷蔵室ダンパ31を開いて冷蔵室7及び野菜室8を冷却しているときに作動し野菜室8内の冷気を拡散または及び循環させるが、この実施の形態では野菜室8に設けた野菜室温度検知手段66の検出温度に基づいても制御するようにしてあるから、冷蔵室7の温度が高くて冷却動作を行なっていないときでも野菜室8の温度が設定温度以上になると回転し始め、野菜室8内に冷気を拡散または及び循環させるようになる。したがって、野菜室温度が高くなって冷却室16からの冷輻射により大きな温度差が生じ結露が発生しやすい条件になると、野菜室ファン53が回転してこれを解消し、効果的に結露発生を防止することができる。   The vegetable compartment fan 53 operates when the refrigerator compartment damper 31 is opened and the refrigerator compartment 7 and the vegetable compartment 8 are cooled by the output from the refrigerator compartment temperature detecting means 65 to diffuse cold air in the vegetable compartment 8. In this embodiment, since the temperature is controlled based on the temperature detected by the vegetable room temperature detecting means 66 provided in the vegetable room 8, the cooling operation is performed when the temperature of the refrigerator room 7 is high. When the temperature of the vegetable compartment 8 becomes equal to or higher than the set temperature even when the temperature is not higher, rotation starts, and cool air is diffused or circulated in the vegetable compartment 8. Therefore, when the temperature of the vegetable compartment increases and a large temperature difference is generated due to the cold radiation from the cooling compartment 16 and the condition where dew condensation is likely to occur, the vegetable compartment fan 53 rotates to eliminate this, and the dew condensation is effectively generated. Can be prevented.
また、上記野菜室8の温度が、野菜室ファン53の回転にもかかわらず前記設定温度よりも若干高い温度に設定している第二設定温度より高くなるようなことがあれば、野菜室ファン53の回転数を上げて冷気の拡散または及び循環量を増強し、更には低温の新鮮冷気の取り込み混入量を増加させることができ、野菜室8を確実に冷却することができる。よって、夏場における冷却不足を解消し野菜等の良好な冷却保存を確実に実現して冷蔵庫の信頼性を高めることができる。   If the temperature of the vegetable compartment 8 becomes higher than the second set temperature which is set slightly higher than the set temperature despite the rotation of the vegetable compartment fan 53, the vegetable compartment fan By increasing the number of revolutions of 53, the amount of diffusion or circulation of cool air can be enhanced, and the amount of cold fresh air taken in and mixed can be increased, so that the vegetable compartment 8 can be reliably cooled. Therefore, the cooling shortage in summer can be resolved, and good cooling and preservation of vegetables and the like can be reliably realized, and the reliability of the refrigerator can be improved.

(Embodiment 2)
FIG. 24 is a schematic cross-sectional view for explaining the cooling air flow when the cooling fan rotates in the vegetable room of the refrigerator according to the second embodiment. FIG. 25 is the cold air flow when the cooling fan stops in the vegetable room of the refrigerator according to the second embodiment. FIG. 3 is a schematic cross-sectional view for explaining the method.
この実施の形態では、野菜室ファン53を野菜冷気入口44とともに野菜室8の天井部に配置するとともに、野菜室ファン53は野菜室上部に吹出口54を開口させ、かつ、野菜冷気戻り口46を野菜室8の下部に設けた構成としてある。そして上記野菜室ファン53は野菜室8と冷蔵室7との間を仕切って野菜室8の天井を構成する仕切板5内に斜めに傾斜させて配置してある。   In this embodiment, the vegetable room fan 53 is arranged on the ceiling of the vegetable room 8 together with the vegetable cool air inlet 44, and the vegetable room fan 53 opens the outlet 54 at the upper part of the vegetable room and has a vegetable cool air return port 46. Is provided below the vegetable compartment 8. The vegetable room fan 53 partitions the space between the vegetable room 8 and the refrigeration room 7 and is disposed obliquely in the partition plate 5 constituting the ceiling of the vegetable room 8.
これにより、この実施の形態の冷蔵庫では、野菜室ファン53が回転すると、図24の実線矢印に示すように野菜室ファン53は野菜冷気入口44から戻り通路38の冷気を吸引して野菜室8内に供給し、大部分の冷気を野菜冷気戻り口46から戻り通路38へと戻すとともに、他の冷気は破線矢印で示すように野菜室8内に拡散及び循環させるようになる。すなわち、前記実施の形態1と同様、冷気を安定的かつ効率よく取り込んで同野菜室8内で循環することになる。また、野菜室ファン53が停止したときには、図25の実線矢印で示すように大部分の冷機は戻り通路38を介して一部の冷気は破線矢印で示すように野菜室8内を冷気が拡散または及び循環する。よって、野菜室8内での結露発生を抑制し良好な状態で野菜を冷却保存することが可能となる。   Thereby, in the refrigerator of this embodiment, when the vegetable room fan 53 rotates, the vegetable room fan 53 sucks the cool air in the return passage 38 from the vegetable cool air inlet 44 as shown by the solid arrow in FIG. And the majority of the cool air is returned from the vegetable cool air return port 46 to the return passage 38, while the other cool air is diffused and circulated into the vegetable compartment 8 as shown by the dashed arrow. That is, similarly to the first embodiment, cool air is stably and efficiently taken in and circulated in the vegetable room 8. Also, when the vegetable room fan 53 is stopped, most of the coolers are diffused through the return passage 38 as shown by the solid line arrows in FIG. Or and circulate. Therefore, it is possible to suppress the occurrence of dew condensation in the vegetable compartment 8 and cool and preserve the vegetables in a good condition.
また、前記野菜室ファン53は野菜室8と冷蔵室7との間を仕切る仕切板5内に配置しているので、野菜室8の冷却を効率の良いものとしつつ野菜室8の容積も確保する形で野菜室ファン53を野菜室8内に設けることができる。すなわち、野菜室8の上部に冷蔵室7が位置しているので、野菜室8はこの冷蔵室7からの冷輻射によって適度に冷却され、その結果、仕切板5は断熱強化のための断熱材を組み込む必要がなくなるので、そのスペースを利用して野菜室ファン53を組み込むことができ、しかも野菜室ファン53は傾斜させて配置してあるから、野菜室ファン53を組み込んでいるのにもかかわらず仕切板5の厚さを大きく増加させる必要がなくなり、その分野菜室8の容積を大きく確保することができるのである。   In addition, since the vegetable room fan 53 is disposed in the partition plate 5 that separates the vegetable room 8 and the refrigerator compartment 7, the cooling of the vegetable room 8 is ensured and the volume of the vegetable room 8 is secured. The vegetable room fan 53 can be provided in the vegetable room 8 in such a manner. That is, since the refrigerator compartment 7 is located above the vegetable compartment 8, the vegetable compartment 8 is appropriately cooled by the cold radiation from the refrigerator compartment 7, and as a result, the partition plate 5 is made of a heat insulating material for enhancing heat insulation. It is not necessary to incorporate the vegetable room fan 53, so that the vegetable room fan 53 can be incorporated by utilizing the space, and since the vegetable room fan 53 is arranged at an angle, the vegetable room fan 53 is installed. Therefore, it is not necessary to increase the thickness of the partition plate 5 greatly, and the volume of the vegetable room 8 can be ensured accordingly.
なお、上記野菜室8背面への冷輻射は、冷却室16はもちろんこの実施の形態では冷却室16の冷却ファン下流側の冷蔵室ダンパ31までの冷却室冷気搬送路30帯域がこの冷却室16と同じ極低温帯の冷却室温度域となっていてこの冷蔵室ダンパ31までの冷却室温度帯域と対向する部分で強い冷輻射を受けるものであり、本発明においてはこの冷却室冷気搬送路30を含む冷却室温度帯域を総称して冷却室16と称す。   In addition, in this embodiment, the cold radiation to the back of the vegetable room 8 is not limited to the cooling room 16, but in this embodiment, the cooling room cold air transport path 30 band to the refrigerator room damper 31 on the downstream side of the cooling fan of the cooling room 16 is formed by the cooling room 16. The cold room temperature range is the same as that of the cold room, and the portion facing the cool room temperature band up to the cold room damper 31 receives strong cold radiation. Is generally referred to as a cooling chamber 16.
以上、本発明の実施の形態を説明してきたが、上記実施の形態で説明した構成は本発明を実施する一例として示したものであり、本発明の目的を達成する範囲で種々変更可能なことは言うまでもない。   As described above, the embodiments of the present invention have been described. However, the configuration described in the above embodiments is shown as an example for carrying out the present invention, and various changes can be made within a range that achieves the object of the present invention. Needless to say.
<その他の実施形態>
例えば、本実施の形態では野菜室8に野菜冷気入口44と野菜冷気戻り口46を別々に設けたものを例示して説明したが、これらは一つにして冷気出入り口とし、その冷気出入り口の前方にオフセット状態にして野菜室ファン53を設けた構成としてもよい。この場合は、野菜空気出入り口の野菜室ファン53側に偏った位置の開口部分から冷気戻り通路38の冷気が野菜室8内に吸引供給され、野菜室ファン53とは反対側に偏った開口部分から野菜室8内の冷気が冷気戻り通路38へと流出するようになる。したがって、野菜室8内への冷気の流出入量は少なくなるものの、これが逆に野菜室内の冷気全部が次々と入れ替わってしまうのを抑制することになる。したがって野菜室8内の冷気は野菜から蒸散した湿気を含む高湿度の冷気が多く保持されて野菜の乾燥劣化を防止することができ、効果的である。そして、野菜室8内では、前記各実施の形態でと同様、野菜室ファン53の回転によって冷気を野菜室内で拡散または及び循環するので、結露発生を防止することができる。
<Other embodiments>
For example, in the present embodiment, an example is described in which the vegetable cold air inlet 44 and the vegetable cold air return port 46 are separately provided in the vegetable room 8. The vegetable room fan 53 may be provided in an offset state. In this case, the cool air in the cool air return passage 38 is sucked and supplied into the vegetable room 8 from the opening portion of the vegetable air inlet / outlet that is biased toward the vegetable room fan 53 side, and the opening portion biased to the opposite side to the vegetable room fan 53. Then, the cool air in the vegetable room 8 flows out to the cool air return passage 38. Therefore, although the amount of cold air flowing into and out of the vegetable compartment 8 is reduced, this suppresses the reverse replacement of all the cool air in the vegetable compartment one after another. Therefore, as the cool air in the vegetable room 8, a large amount of high-humidity cool air including moisture evaporating from the vegetables is held, and drying and deterioration of the vegetables can be prevented, which is effective. Then, in the vegetable compartment 8, as in the above-described embodiments, the cool air is diffused or circulated in the vegetable compartment by the rotation of the vegetable compartment fan 53, so that the occurrence of dew condensation can be prevented.
また、本実施の形態では野菜室8を冷蔵室7と冷凍室9との間に設けた真ん中野菜タイプの冷蔵庫を例にして説明したが、これは野菜室8が最下部にあるタイプの冷蔵庫であっても野菜室8と冷凍室9の背面に渡って冷却室16が設置されているものであればよいものである。   Also, in the present embodiment, a description has been given by taking as an example a middle vegetable type refrigerator in which the vegetable compartment 8 is provided between the refrigerator compartment 7 and the freezing compartment 9, but this is a refrigerator in which the vegetable compartment 8 is at the bottom. Even if it is, what is necessary is just a thing provided with the cooling room 16 over the back of the vegetable room 8 and the freezing room 9.
また、野菜室8への冷気の供給/停止は、冷蔵室ダンパ31を兼用して行うようにしたが、野菜室専用のダンパを設けて供給/停止を行わせるようにしてもよく、その際には野菜室ファン53と同様冷蔵室温度検知手段65及び野菜室温度検知手段66の出力により野菜室ファン53と連動させて供給/停止或いは単独で供給/停止動作させるようにすればよい。   In addition, the supply / stop of the cool air to the vegetable compartment 8 is performed using the refrigerator compartment damper 31 as well. However, the supply / stop may be performed by providing a damper dedicated to the vegetable compartment. As in the case of the vegetable room fan 53, the supply / stop operation or the supply / stop operation may be performed in conjunction with the vegetable room fan 53 by the outputs of the refrigerator compartment temperature detecting means 65 and the vegetable room temperature detecting means 66 in the same manner as the vegetable room fan 53.
さらに、野菜室ファン53は野菜室8に設けた野菜室温度検知手段66からの出力によって制御するものを例示したが、これは冷蔵室温度検知手段65の出力に連動させて制御するようにしてもよく、あるいは間歇的に所定時間回転を繰り返すようにしてもよいものであり、冷蔵庫の特性に応じて適宜選択すればよい。   Furthermore, although the vegetable room fan 53 is controlled by the output from the vegetable room temperature detecting means 66 provided in the vegetable room 8, this is controlled in conjunction with the output of the refrigerator room temperature detecting means 65. Alternatively, the rotation may be repeated intermittently for a predetermined time, and may be appropriately selected according to the characteristics of the refrigerator.
更に圧縮機15も冷蔵庫本体1の上部後方領域に設置したものを説明したが、これも実施の形態で説明したものに限られるものではなく、例えば圧縮機15は冷蔵庫本体1の下部後方に設けてあってもよいものである。   Furthermore, although the compressor 15 has been described as being installed in the upper rear area of the refrigerator main body 1, this is not limited to the one described in the embodiment, and for example, the compressor 15 is provided in the lower rear of the refrigerator main body 1. It may be.
本発明にかかる冷蔵庫は、冷却能力が大きな冷蔵庫であっても野菜室内の結露発生を抑制し、良好な状態で野菜を冷却保存することができ、家庭用はもちろん業務用冷蔵庫にも幅広く適用することができる。   INDUSTRIAL APPLICABILITY The refrigerator according to the present invention can suppress the occurrence of dew condensation in the vegetable compartment even if the refrigerator has a large cooling capacity, can cool and store vegetables in a good state, and is widely applied to not only household refrigerators but also commercial refrigerators. be able to.
