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。 The present invention relates to a refrigerator, and in particular to a cold storage configuration for 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。 Generally, a household refrigerator is configured by providing a plurality of storage rooms having different temperature bands, for example, a refrigerator room, a vegetable room, and a freezer room, in the refrigerator body. The layout of the refrigerator compartment, vegetable compartment, and freezer compartment is largely divided into two according to the actual usage of the user, one of which is the type in which the freezer compartment is arranged at the upper and lower center portions of the refrigerator main body that is most easily used by 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 a type in which a freezing room is arranged at a substantially central portion in the upper and lower sides of the refrigerator body have become the mainstream of today's refrigerators, and are easy to use for users who frequently use frozen foods as lifestyle changes. Many have been proposed (see, for example, Patent Document 1).
図２５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. 25 shows a refrigerator described in Patent Document 1. A refrigerator room 101 is provided in the upper part of the refrigerator body 100, a vegetable room 102 is provided in the lower part, and a freezer room 103 is provided at a substantially upper and lower central part of the refrigerator body 100 between these two rooms. It is arranged. This refrigerator is provided with a cooling chamber 104 on the back side across the vegetable compartment 102 and the freezing chamber 103 of the refrigerator main body 100, and a cooler 105 and a cooling fan 106 are arranged in the cooling chamber 104. The generated cold air is supplied to the refrigerating room 101, the vegetable room 103, and the freezing room 102 by the cooling fan 106 and circulated, and the food stored in 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）。 In addition, a refrigerator of a type in which a vegetable room is arranged at a substantially central portion of the top and bottom of the refrigerator body is abbreviated as a middle vegetable refrigerator, and has been proposed as being easy to use for users who mainly use vegetables in and out (for example, patents) Reference 1).
図２６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. 26 shows a refrigerator described in Patent Document 2, in which a refrigerator compartment 201 is provided at the top of the refrigerator body 200 and a freezer compartment 202 is provided at the bottom. A chamber 203 is arranged. In the same manner as described above, this refrigerator is also provided with a cooling chamber 204 across the freezer compartment 202 and the vegetable compartment 203 of the refrigerator main body 200, and a cooler 205 and a cooling fan 206 are disposed in the cooling chamber 204. The cold air generated by the cooler 205 is supplied to the refrigeration room 201, the vegetable room 203, and the freezing room 202 by the cooling fan 206 and circulated, and the food stored in 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 cold air generated in the cooling room is circulated to the vegetable room via the refrigerating room, and the vegetables stored in the vegetable room are cooled and stored by the circulating cold 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, in any of the conventional refrigerators described in Patent Document 1 and Patent Document 2, condensation may occur in the vegetable compartments 103 and 203 during the cold storage of vegetables. In such a case, the vegetables stored in this There has been a problem of degrading.
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 and 203 receive cold radiation from the cooling compartments 104 and 204 located on the back thereof, and the temperature near the back of the vegetable compartments 103 and 203 is likely to be lowered due to this cold radiation. It occurred. In particular, the vegetable compartments 103 and 203 are supplied with cool air having a relatively high temperature after the refrigerator compartments 101 and 201 are cooled as described above. Under such circumstances, the vegetable compartments 103 and 203 are provided with the vegetable compartment 103. , 203 continues to receive strong cold radiation from the cooling chambers 104, 204 provided at the back, so that the temperature of the corresponding portion, that is, the back portion facing the cooling chambers 104, 204 is lowered, and the cold air temperature in the vegetable chamber is reduced. A big temperature difference arises between them, and dew condensation arises near the back part of the vegetable storage case provided in vegetable compartment 103,203.
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 cooling radiation from the cooling chambers 104 and 204 so that it does not occur under normal use, but many vegetables or large vegetables such as cabbage are temporarily in the vegetable chambers 103 and 203. When the vegetables are stored in the cabinet, the temperature in the vicinity of the vegetables rises due to the heat of the vegetables, and the temperature difference inevitably increases due to the cold radiation from the cooling chambers 104 and 204, so that the cold air in the vegetables chamber is condensed on the wall of the vegetable storage case. I started to do. Especially in recent refrigerators, large-sized plastic bottles and packs of drinking water, tea, and juice are now stored in vegetable storage cases, and such 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 in the vicinity of the vegetables and plastic bottles starts to rise immediately after the storage and the temperature difference due to the cold radiation from the cooling chambers 104 and 204 is large. There is a tendency that the problem of vegetable deterioration due to condensation of cold air in the vegetable room becomes obvious.
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 a refrigerator abbreviated as a middle vegetable, and is likely to become a problem. This is because the middle vegetable type refrigerator receives cold radiation also from the freezer compartment 202 where the bottom of the vegetable compartment 203 is located below, so the cold radiation from the freezer compartment 202 is also added and the vegetable room is synergistic with both. This is because the vicinity of the rear lower portion of 203 is likely to be lowered in temperature, which is unavoidable in a large refrigerator in which the cooling chamber 204 is located up to 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 condensation problem is likely to occur in summer when the temperature of drinking water such as vegetables and plastic bottles purchased, tea, and juice tends to be relatively high. As a result, the temperature of the whole vegetable room is high in this case. It tends to be noticeable, the amount of condensed water increases, the temperature of the vegetable room increases, and vegetables and plastic bottles cannot be stored in a sufficiently cold storage. There was also the fear that it would give the impression that there was no such thing 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 of the techniques for solving such a problem, as disclosed in JP-A-11-118314, a cooling chamber is provided only on the back surface of the freezing room and is not positioned on the back surface portion 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 it cannot be applied to a large-capacity large refrigerator. Therefore, the problem of vegetable deterioration due to dew condensation caused by dehydration cannot be solved.
本発明はこのような点に鑑みてなしたもので、冷凍能力の大きな大型の冷蔵庫であっても野菜室内での結露を解消して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 has been made in view of these points, and an object of the present invention is to provide a refrigerator that can cool and store vegetables and the like by eliminating condensation in the vegetable room even in a large refrigerator having a large freezing capacity. It is what.
本発明は、上記従来の課題を解決するために、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の野菜収納ケースの後方に野菜室ファンを設け、前記野菜室ファンによって吹出す冷気の吹出口は前記野菜収納ケースの後面に向かって開口し、前記野菜室ファンと対向する前記後面に傾斜面を形成し、冷気が前記傾斜面にガイドされて前記野菜収納ケースと前記野菜室の内周壁との間に形成された空間を循環する構成としてある。 In order to solve the above-described conventional problems, the present invention includes a refrigerator room, a vegetable room, and a freezer room, and coolers generated by a cooler and a cooler for generating cold air are provided on the back of the freezer room and the vegetable room. A refrigerator including a cooling fan and the like for supplying and circulating to a room, a vegetable room, a freezing room, and the cooling fan for circulating cold air to the refrigeration room, the freezing room, and the vegetable room A vegetable room fan is provided at the rear of the vegetable storage case in the vegetable room, and a cold air outlet blown out by the vegetable room fan opens toward the rear surface of the vegetable storage case and is inclined to the rear surface facing the vegetable room fan A surface is formed, and cold air is guided by the inclined surface and circulates in a space formed between the vegetable storage case and the inner peripheral wall of the vegetable compartment .
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野菜室内の冷気を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発生を抑制することができる。 Thus, in this refrigerator, the vegetable room fan is rotated to diffuse or circulate the cold air in the vegetable room, thereby suppressing the occurrence of a large temperature difference in the part that receives the cold radiation from the cooling room. Condensation caused by cold radiation can be prevented, and even if the cooler for generating cold air is enlarged so that the cooling room becomes a large refrigerator with a large capacity spanning the freezing room and the vegetable room, cooling from the cooling room can be prevented. Condensation caused by radiation can be suppressed.
本発明の冷蔵庫は、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る信頼性の高い冷蔵庫とすることができる。 The refrigerator of the present invention can be a highly reliable refrigerator that suppresses the occurrence of dew condensation in the vegetable compartment even when the refrigerator has a large cooling capacity and can cool and store the vegetables in a good state.
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の野菜収納ケースの後方に野菜室ファンを設け、前記野菜室ファンによって吹出す冷気の吹出口は前記野菜収納ケースの後面に向かって開口し、前記野菜室ファンと対向する前記後面に傾斜面を形成し、冷気が前記傾斜面にガイドされて前記野菜収納ケースと前記野菜室の内周壁との間に形成された空間を循環する構成としてある。 1st invention is equipped with a refrigerator compartment, a vegetable compartment, and a freezer compartment, The cold air produced | generated by the cooler and cooler for cold air generation | occurrence | production on the back of the said freezer compartment and a vegetable compartment is put into the said refrigerator compartment, a vegetable compartment, and a freezer compartment A refrigerator provided with a cooling chamber comprising a cooling fan and the like for supply and circulation, and in addition to the cooling fan for circulating cold air to the refrigerator compartment, freezer compartment, vegetable compartment, and further behind the vegetable storage case in the vegetable compartment A vegetable room fan is provided , and a cold air outlet that is blown out by the vegetable room fan opens toward the rear surface of the vegetable storage case, forms an inclined surface on the rear surface facing the vegetable room fan, and the cold air is It is set as the structure which circulates through the space formed between the said vegetable storage case and the inner peripheral wall of the said vegetable chamber guided by the inclined surface .
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野菜室内の冷気を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, the vegetable room fan is rotated to diffuse or circulate the cold air in the vegetable room, thereby suppressing the occurrence of a large temperature difference in the part that receives the cold radiation from the cooling room. Condensation caused by cold radiation can be prevented, and even if the cooler for generating cold air is enlarged so that the cooling room becomes a large refrigerator with a large capacity spanning the freezing room and the vegetable room, cooling from the cooling room can be prevented. Condensation due to radiation can be suppressed. Therefore, in the refrigerator in the whole area from the small-capacity small refrigerator to the large-capacity large-sized refrigerator, it is possible to suppress the vegetable deterioration due to the dew condensation water generated by the cold radiation from the cooling chamber and to cool and store the vegetables in a better state. It becomes possible.
第２の発明は、第１の発明において、野菜室には冷却室からの冷気が循環する冷気通路に連通する開口を一つだけ設けて野菜冷気出入り口とした構成としてある。 According to a second aspect of the present invention, in the first aspect, the vegetable compartment is provided with only one opening that communicates with a cold passage through which the cold air from the cooling compartment circulates, thereby forming a vegetable cold air inlet / outlet.
これにより、野菜室には当該野菜室と冷気通路との間の圧力差により冷気通路を流れる冷気が野菜冷気出入り口を介して流れ込み、その流れ込んだ冷気が野菜室内を冷却した後前記野菜冷気出入り口より冷気通路へと流出するから、野菜室内に流入し野菜室から流出する冷気の量が少なくなって、野菜室内の冷気は野菜から蒸散した湿気を含む高湿度のままの状態に維持されるようになる。そして野菜室ファンの回転により上記野菜冷気出入り口を介しての冷気の出入りが積極化されるものの、野菜室内の冷気が入れ替わってしまうほどの冷気の出入りは起こらず、野菜室内の冷気を野菜室内で循環させるようになるから、冷却室からの冷輻射に起因する結露発生も防止することができる。したがって野菜室内の野菜を結露によって劣化させるのを防止すると同時に、野菜室内の野菜を冷気の循環によって乾燥劣化させてしまうのを低減することもでき、更に良好な状態で野菜を冷却保存することができる。 As a result, the cold air flowing through the cold air passage flows into the vegetable compartment through the vegetable cold air inlet / outlet due to the pressure difference between the vegetable compartment and the cold air passage, and the cold air flowing in cools the vegetable compartment from the vegetable cold air inlet / outlet. Since it flows out into the cold air passage, the amount of cold air flowing into the vegetable room and out of the vegetable room is reduced, so that the cold air in the vegetable room is maintained at a high humidity state including moisture transpiration from the vegetables. Become. And the rotation of the vegetable room fan will actively bring in and out the cold air through the vegetable cold air entrance, but the cold air will not enter and exit the vegetable room so that the cold air in the vegetable room will be replaced. Since it is circulated, it is possible to prevent the occurrence of condensation due to the cold radiation from the cooling chamber. Therefore, it is possible to prevent the vegetables in the vegetable room from deteriorating due to condensation, and at the same time, it is possible to reduce the drying and deterioration of the vegetables in the vegetable room due to the circulation of cold air. it can.
第３の発明は、第２の発明において、野菜室ファンは野菜冷気出入り口にオフセット状態にして配置した構成としてある。 According to a third invention, in the second invention, the vegetable room fan is arranged in an offset state at the vegetable cold air inlet / outlet.
これにより、野菜室冷気出入り口を介して行われる冷気の出入りが円滑に行われ、冷気の出入りが滞るなどして野菜の冷却保存が十分でなくなるような事態が発生するのを防止でき、常に良好な状態で野菜を冷却保存することができる。 As a result, it is possible to smoothly prevent cold air from entering and exiting through the vegetable room cold air entrance and exit, and to prevent the occurrence of cold storage of vegetables due to lagging in and out of cold air. Vegetables can be stored in a cool state.
第４の発明は、第１の発明において、野菜室には冷却室からの冷気が循環する冷気通路と連通する野菜冷気入口と野菜冷気戻り口とを設けた構成としてある。 According to a fourth invention, in the first invention, the vegetable room is provided with a vegetable cold air inlet and a vegetable cold air return port communicating with the cold air passage through which the cold air from the cooling room circulates.
これにより、一つの野菜冷気出入り口から冷気を出入りするようにした場合に比べ冷気の出入りは滞ることなく円滑でより多くの冷気が野菜室８内に流れ込むものとなり、野菜室内に冷気を効率よく取り込んで、野菜室８内を強力に冷却することができる。 As a result, compared with the case where cold air enters and exits from one vegetable cold air inlet / outlet, the cold air enters and exits smoothly and more cold air flows into the vegetable room 8, and the cold air is efficiently taken into the vegetable room. Thus, the inside of the vegetable compartment 8 can be cooled strongly.

Vegetables can be stored in a cool state.
第７の発明は、第１〜第６の発明において、野菜室ファンは野菜収納ケースの上部開口縁より下方部分に配置した構成としてある。 7th invention is set as the structure arrange | positioned in the lower part rather than the upper opening edge of the vegetable storage case in the 1st-6th invention.
これにより、野菜室ファンによって拡散または及び循環する冷気は野菜収納ケース内に入り込みにくくなって野菜収納ケース内を冷気が循環し野菜を乾燥劣化させてしまうのを防止でき、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。 As a result, it is possible to prevent the cool air diffused and / or circulated by the vegetable room fan from entering the vegetable storage case and preventing the cold air from circulating in the vegetable storage case and causing the vegetables to dry and deteriorate, resulting in a fresher and better state. The vegetables can be stored cold.
第８の発明は、第１〜第７の発明において、野菜室の冷却室と対向する背面部に野菜室通路部を形成し、前記野菜室通路部は野菜室の上部空間に連通させるとともに下部に野菜室ファンを配置した構成としてある。 An eighth invention is the first to seventh inventions, wherein a vegetable room passage portion is formed in a back portion facing the cooling chamber of the vegetable compartment, and the vegetable compartment passage portion communicates with an upper space of the vegetable compartment and is formed in a lower portion. It has a configuration with a vegetable room fan.
これにより、野菜室ファンの回転によって野菜室内の冷気を野菜室通路部を介し効率よく野菜室内で拡散または及び循環させることができ、さらに効果的に野菜室内での結露発生を抑制することができる。 Accordingly, the cold air in the vegetable compartment can be efficiently diffused or circulated in the vegetable compartment through the vegetable compartment passage portion by the rotation of the vegetable compartment fan, and the occurrence of condensation in the vegetable compartment can be more effectively suppressed. .
第９の発明は、第６〜第８の発明において、野菜収納ケースはその一部にペットボトル等の非野菜収納部を有し、かつ野菜室ファンは前記非野菜収納部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配置した構成としてある。 A ninth invention is the sixth to eighth inventions, wherein the vegetable storage case has a non-vegetable storage portion such as a plastic bottle in a part thereof, and the vegetable compartment fan faces the non-vegetable storage portion in the vegetable compartment. The cold air is arranged to diffuse or circulate.
これにより、野菜室ファンからの冷気は非野菜収納部の周りを集中的に循環するようになり、野菜よりも熱容量が大きくて冷えにくいペットボトル等を迅速かつ効率よく冷却することができ、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て結露発生を効果的に防止すると同時に、野菜の冷却保存も良好に行うことができる。 As a result, the cold air from the vegetable compartment fan circulates intensively around the non-vegetable storage unit, which can quickly and efficiently cool PET bottles that have a larger heat capacity than vegetables and are difficult to cool, The increase in the temperature of the vegetable room due to the storage of bottles and the like can be efficiently suppressed to effectively prevent the formation of condensation, and at the same time, the vegetables can be well preserved in the cold state.
第１０の発明は、第９の発明において、野菜室は野菜収納ケースの非野菜収納部側の上部に野菜室ファンの吸引側と連通する第一の野菜冷気吸込み口を設け、この第一の野菜冷気吸込み口と野菜室ファンとを野菜収納ケースの非野菜収納部側の部分に設けた構成としてある。 According to a tenth aspect, in the ninth aspect, the vegetable compartment is provided with a first vegetable cold air inlet that communicates with the suction side of the vegetable compartment fan at the upper part of the vegetable compartment case on the non-vegetable compartment side. It is set as the structure which provided the vegetable cold air inlet and the vegetable compartment fan in the part by the side of the non-vegetable storage part of a vegetable storage case.
これにより、野菜室ファンからの冷気を非野菜収納部分にさらに効率よく集中的に拡散循環させることができ、ペットボトル等を効率よく冷却することができる。 Thereby, the cold air from the vegetable compartment fan can be diffused and circulated more efficiently and intensively in the non-vegetable storage portion, and the PET bottles and the like can be efficiently cooled.
第１１の発明は、第１０発明において、野菜収納ケースの非野菜収納部は野菜収納ケース内を左右に仕切ってそのいずれか一方を非野菜収納部とするとともに、野菜室ファンは前記非野菜収納部の後部下方に配置し、かつ、野菜室内には前記野菜室ファンの吸引側と連通する第二の野菜冷気吸込み口を前記野菜ファンと略対角位置の野菜室上部に設けた構成としてある。 In an eleventh aspect based on the tenth aspect, the non-vegetable storage portion of the vegetable storage case partitions the inside of the vegetable storage case left and right to make one of them a non-vegetable storage portion. The vegetable room is provided with a second vegetable cold air inlet that communicates with the suction side of the vegetable room fan in the upper part of the vegetable room at a position substantially diagonal to the vegetable fan. .
これにより、野菜室ファンからの冷気は野菜収納ケースの非野菜収納部底面部分を通って前方へと野菜室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戻り口へと流れる様になるから、野菜室ケース内への冷気の入り込みを防止しつつ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、野菜ケース内の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。 As a result, the cold air from the vegetable compartment fan diffuses and circulates through the bottom of the vegetable storage case through the bottom portion of the non-vegetable storage portion of the vegetable storage case, and returns to the second vegetable cold air at the top of the vegetable compartment. Since it flows to the mouth, it is possible to diffuse or circulate the cold air widely around the vegetable case while preventing the cold air from entering the vegetable room case. It can be cooled effectively.
第１２の発明は、第８〜第１１の発明において、冷却室から冷蔵室への冷蔵冷気の往き通路部分を冷蔵庫本体背面の略中央部に、前記冷蔵室から冷却室への冷蔵冷気の戻り通路部分を冷蔵庫本体背面の前記冷蔵冷気の往き通路部分側方に配置するとともに、野菜室に設けた野菜室通路部は前記冷蔵冷気の戻り通路部分の前方に縦設した構成としてある。 A twelfth aspect of the invention is that, in the eighth to eleventh aspects of the invention, the refrigerated cool air going-out passage portion from the cooling chamber to the refrigerating chamber is set at the substantially central portion on the back of the refrigerator body, and the refrigerating cold air from the refrigerating chamber to the cooling chamber is returned The passage portion is arranged on the side of the refrigerated cold air going-out passage portion on the back of the refrigerator main body, and the vegetable compartment passage portion provided in the vegetable compartment is vertically arranged in front of the refrigerated cold air return passage portion.
これにより、野菜室通路部は、風路断面積を小さく設定できる冷蔵室から冷却室への冷蔵冷気の戻り通路部分と重なり、風路断面積を大きく設定する必要のある冷蔵冷気の往き通路部分では前後方向に重なることがないので、野菜室の奥行き寸法を拡大することができ、野菜を良好な状態で冷却保存可能にしつつ野菜収納量も多くすることができ、使い勝手の良い冷蔵庫とすることができる。 Thereby, the vegetable room passage part overlaps with the return passage part of the refrigerated cold air from the refrigeration room to the cooling room where the air passage sectional area can be set small, and the refrigerated cold air outgoing passage part where the air passage sectional area needs to be set large. Because it does not overlap in the front-rear direction, the depth dimension of the vegetable room can be expanded, the vegetable storage capacity can be increased while allowing the vegetables to be stored in a cool state in a good state, and a refrigerator that is easy to use Can do.
第１３の発明は、第８〜第１２の発明において、野菜室はその野菜冷気出入り口を冷蔵室からの冷蔵冷気戻り通路部分に開口させるとともに、冷却室からの冷気の一部がバイパスして冷蔵室からの戻り冷気に混流して野菜室に供給される構成としてある。 In a thirteenth aspect based on the eighth to twelfth aspects, the vegetable compartment opens the vegetable cold air inlet / outlet to the refrigerated cold air return passage portion from the refrigerated compartment, and a portion of the cold air from the cold compartment bypasses the refrigerated compartment. It is configured to be mixed with the return cold air from the room and supplied to the vegetable room.
これにより、冷蔵室からの冷蔵室戻り冷気によって野菜室を冷却すると同時に、野菜室ファンの回転により野菜室内冷気の野菜室内拡散または及び循環時には、当該野菜室ファンの回転によって冷却室からの新鮮な低温冷気を直接取り込み混入させ効果的に野菜室内を冷却することができ、しかも野菜室ファンの回転数を上げることによって新鮮な低温冷気の取り込み混入量を増加させることができ、野菜室への冷気の流れ込み量が少なく、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ている時でも、これを確実に冷却することができるとともに、冷却室からの冷輻射による結露発生も抑制でき、野菜を良好な状態で冷却保存することができる。 As a result, the vegetable room is cooled by the cold room return cold air from the cold room, and at the same time the vegetable room cold air is diffused or circulated by the rotation of the vegetable room fan, the fresh air from the cooling room is rotated by the rotation of the vegetable room fan. The low temperature cold air can be directly taken in and mixed to effectively cool the vegetable room, and the amount of fresh low temperature cold air taken in can be increased by increasing the rotation speed of the vegetable room fan. Even when a large amount of room temperature PET bottles with a large heat capacity are stored, it can be cooled reliably, and it can also prevent the occurrence of condensation due to cold radiation from the cooling chamber. It can be stored in a cool state in a good state.
第１４の発明は、第１〜第１３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 fourteenth aspect based on the first to thirteenth aspects, the vegetable room fan is controlled based on the temperature detected by the 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が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。 As a result, the vegetable room fan can be driven when the temperature of the vegetable room becomes equal to or higher than the predetermined temperature to diffuse or circulate the cold air in the vegetable room, and the vegetable room fan when the temperature becomes higher than the predetermined temperature. Increase the number of rotations to increase the diffusion or circulation of cold air, and in addition to the type that incorporates fresh low temperature cold air, the amount of contamination can be increased and the vegetable room can be reliably cooled, It is possible to improve the reliability of the refrigerator by eliminating the lack of cooling in the summer and reliably realizing good cold storage of vegetables and the like.

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。 About the refrigerator comprised as mentioned above, the operation | movement and an effect | action are demonstrated 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。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。 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 to some extent by a condenser (not shown), and further, refrigerant piping (not shown) disposed on the side and rear surfaces of the refrigerator and the front opening of the refrigerator. Etc.), while condensing and liquefying while preventing condensation in the refrigerator, it reaches a capillary tube (not shown). Thereafter, the capillary tube is depressurized while exchanging heat with a suction pipe (not shown) to the compressor 15 and becomes a low-temperature and low-pressure liquid refrigerant and reaches the cooler 18 in the cooling chamber. Here, the refrigerant in the cooler 18 evaporates, and cool air for cooling each storage chamber 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 cold 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 chamber 16 is sent by the cooling fan 19 from the cooling chamber cold-air conveyance path 30 to the refrigerator compartment 7 and the freezer compartment 9, and the cold air supplied to the refrigerator compartment 7 cools the refrigerator compartment 7. After that, it is supplied to the vegetable room 8 and each room is cooled to the set temperature. Then, the cold 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 cold air supply to each of the chambers is performed by the control unit 68 operating / stopping the compressor 15 and the cooling fan 19 based on the temperatures detected by the refrigerator temperature detecting means 65 and the freezer temperature detecting means 67, and the refrigerator temperature damper 31. The freezer damper 34 is controlled to open and close so that each chamber is maintained in a set temperature range.
次に、野菜室８の冷却動作について説明する。 Next, the cooling operation of the vegetable compartment 8 will be described.
野菜室８は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出入り口４４から供給されて冷却される。この冷気は、野菜室８に設けられている開口が野菜冷気出入り口４４一つであるため、冷却ファン１９の運転中、すなわち冷却運転中は、冷却ファン１９の送風によって生じる野菜室８と戻り通路３８との間の圧力差により野菜室内の冷気の一部が入れ替わるような形で緩やかに野菜室８に流れ込み、野菜収納ケース４８と野菜室８の内周壁との間の空間を流れ、この野菜収納ケース４８内に収納されている野菜やペットボトル等をケース外周から間接的に冷却し、前記野菜冷気出入り口４４から戻り通路３８へと流出して、冷気戻りダクト４０から冷却室１６へと循環する。 In the vegetable compartment 8, the cold air after cooling in the refrigerator compartment is supplied and cooled from the vegetable cold air inlet / outlet 44 provided in the cold air return passage 38 as shown in FIG. Since this cold air has only one vegetable cold air inlet / outlet opening 44 provided in the vegetable compartment 8, during the operation of the cooling fan 19, that is, during the cooling operation, the vegetable compartment 8 and the return passage generated by the cooling fan 19 blow air. Gently flows into the vegetable compartment 8 in such a way that part of the cold air in the vegetable compartment is replaced by the pressure difference between the vegetable compartment 38 and the space between the vegetable storage case 48 and the inner peripheral wall of the vegetable compartment 8. Vegetables, plastic bottles and the like stored in the storage case 48 are indirectly cooled from the outer periphery of the case, flow out from the vegetable cold air inlet / outlet 44 to the return passage 38, and circulate from the cold air return duct 40 to the cooling chamber 16. To do.
そのため、前記野菜室８内に出入りする冷気は、冷気出入り口を別々に設けた場合に比べ緩やかでその量も比較的少ないものとなる。したがって、野菜室８内の冷気は若干量が入れ替わる程度となり、大部分は野菜室８内にとどまった状態となる。すなわち、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ままの状態に維持されるようになる。よって、野菜室８内の冷気が大量に循環して入れ替わるような場合に比べ野菜の乾燥劣化を大きく低減させることができ、従来に比べかなり良好な状態で野菜を冷却保存することが可能となっている。 Therefore, the cold air entering and exiting the vegetable compartment 8 is gradual and the amount thereof is relatively small compared to the case where the cold air inlet / outlet is provided separately. Therefore, the amount of cold air in the vegetable room 8 is slightly changed, and most of the cold air remains in the vegetable room 8. That is, the cold air in the vegetable room 8 is maintained in a high humidity state including the moisture transpiration from the vegetables. Therefore, compared with the case where the cool air in the vegetable room 8 is circulated and replaced in large quantities, the drying deterioration of the vegetables can be greatly reduced, and the vegetables can be stored in a cooled state in a considerably better state than before. ing.
一方、この実施の形態で示す冷蔵庫では図１２で示したように野菜室８の野菜室通路部５０下部であって前記野菜冷気出入り口４４と対向する部分に野菜室ファン５３が設けら
れており、この野菜室ファン５３が冷却運転中に回転すると、戻り通路３８を流れる戻り冷気の多くが前記野菜冷気出入り口４４から野菜室通路部５０内へと吸引され、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。
On the other hand, in the refrigerator shown in this embodiment, as shown in FIG. 12, a vegetable room fan 53 is provided at a lower portion of the vegetable room passage portion 50 of the vegetable room 8 and facing the vegetable cold air inlet / outlet 44. When the vegetable compartment fan 53 rotates during the cooling operation, most of the return cold air flowing through the return passage 38 is sucked into the vegetable compartment passage portion 50 from the vegetable cold air inlet / outlet 44 and the vegetable compartment fan 53 blows out the vegetables. The lower vegetable storage case 49a in the chamber 8 is supplied toward the rear surface.
ここでこの実施の形態では、前記野菜室ファン５３が野菜冷気出入り口４４とオフセット状態となっているから、前記した野菜冷気出入り口４４を介して行われる冷気の出入りは開口が野菜冷気出入り口４４一つであっても円滑なものとなり、確実な吸引取り込みが可能となる。すなわち、図１２の（Ｘ）（Ｙ）で示すように野菜室ファン５３の中心軸に近い野菜冷気出入り口４４の下端寄り部分（図１２中の下部）ではＸで示すように冷気が野菜室８内に流れ込み、野菜室ファン５３の中心軸から遠い野菜冷気出入り口４４の上端寄り部分（図１２中の上部）ではＹで示すように冷気が野菜室８から流出する様に明確に区分されるようになる。したがって、一つの野菜冷気出入り口４４であっても冷気の出入りが入り乱れてこれが滞り結果的に冷気取り込み不足を招来することを防止でき、戻り通路３８内より確実に冷気を吸引取り込みして野菜室ファン５３の吹出口５４より野菜室８内に供給することができる。 Here, in this embodiment, since the vegetable room fan 53 is offset from the vegetable cold air inlet / outlet 44, the opening / closing of the cold air performed through the vegetable cold air inlet / outlet 44 is one vegetable cold air inlet / outlet. However, it becomes smooth and reliable suction and intake becomes possible. That is, as shown by (X) and (Y) in FIG. 12, in the portion near the lower end of the vegetable cold air inlet / outlet 44 close to the central axis of the vegetable room fan 53 (lower part in FIG. 12) In the portion near the upper end of the vegetable cold air inlet / outlet 44 (upper part in FIG. 12) that flows into the vegetable room fan 53 and far from the central axis of the vegetable room fan 53, the cold air is clearly divided so as to flow out of the vegetable room 8 as indicated by Y. become. Accordingly, it is possible to prevent the cold air from entering and exiting even if the single vegetable cold air inlet / outlet 44 is disturbed, resulting in a shortage of cold air being taken in. As a result, the cold air is surely sucked and taken in from the return passage 38 and the vegetable room fan is obtained. It can be supplied into the vegetable compartment 8 from 53 outlets 54.
そして、この場合でも冷気出入り口が一つであるため、冷気出入り口を別々に設けている場合に比べ野菜室内冷気の入り代わり量は少なく、野菜室８内は高湿度状態に保持されて野菜の乾燥劣化防止効果が維持される。 And even in this case, since there is only one cold air inlet / outlet, the amount of cold air in the vegetable room is less than in the case where the cold air inlet / outlet is provided separately, and the vegetable room 8 is kept in a high humidity state to dry the vegetables. The effect of preventing deterioration is maintained.
以上のようにして野菜室８内に取り込まれ、野菜室８の野菜収納ケース４８に向かって供給された冷気は、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前記冷却ファン１９の送風圧によって循環する際の流れよりも早く流れ、前記した如く野菜冷気出入り口４４から戻り通路３８を介して冷却室１６へと戻り循環する。その際、冷却室１６へと戻り循環する冷気以外の冷気は野菜室８の上部に設けた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より第一の通路４７ａ及び第二の通路５１ａに吸引され、これらの通路と連通している野菜室通路部５０を介して野菜室ファン５３に吸引され当該野菜室ファン５３の吹出口５４から再び野菜室８内の野菜収納ケース４８に向けて供給され、野菜室８内を拡散及び循環する。 As described above, the cold air taken into the vegetable compartment 8 and supplied toward the vegetable storage case 48 in the vegetable compartment 8 passes through the space between the vegetable storage case 48 and the bottom and inner peripheral walls of the vegetable compartment 8. It flows faster than the flow when it is circulated by the blowing pressure of the cooling fan 19, and returns to the cooling chamber 16 through the return passage 38 from the vegetable cold air inlet / outlet port 44 as described above. At that time, cool air other than the cool air returning to the cooling chamber 16 is circulated from the first vegetable cold air inlet 47 and the second vegetable cold air inlet 51 provided in the upper portion of the vegetable chamber 8. The vegetable storage case 48 in the vegetable compartment 8 is again sucked by the vegetable compartment fan 53 through the vegetable compartment passage portion 50 communicating with these passages 51a and from the outlet 54 of the vegetable compartment fan 53. Is distributed and circulated in the vegetable compartment 8.
次に、野菜室８の結露防止について説明する。 Next, prevention of condensation in the vegetable room 8 will be described.
野菜室８は前記のようにして冷却されるが、その背面に位置している冷却室１６及び下方に位置する冷凍室９からの冷輻射を受け、従来と同様その背面下部近傍が低温化しやすい。特に冷却室１６からの冷輻射が強く、野菜室８背面への冷輻射は、冷却室１６自体はもちろん冷却室１６から冷蔵室ダンパ３１に至る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、この部分が低温化しやすい。 Although the vegetable compartment 8 is cooled as described above, it receives cold radiation from the cooling compartment 16 located on the back surface and the freezer compartment 9 located below, and the vicinity of the lower part of the back surface is likely to be lowered in temperature as in the past. . In particular, the cold radiation from the cooling chamber 16 is strong, and the cooling radiation from the cooling chamber 16 itself to the refrigerator compartment damper 31 as well as the cooling chamber 16 itself is the cooling chamber cold air conveyance path 30 zone from the cooling chamber 16 itself. The cooling chamber temperature region is the same as that in the cryogenic temperature zone 16, and strong cold radiation is received at the portion facing the cooling chamber temperature zone up to the refrigerator compartment damper 31, and this portion is easily lowered in temperature.
この冷輻射による野菜室背面下部近傍の低温化は、冷却運転中及び冷却停止中の何れの場合にも、前記野菜室ファン５３の駆動により野菜室８内の冷気を拡散及び循環させることによって解消する。すなわち、前記した野菜室ファン５３が駆動すると、野菜室８内の冷気が前記したように拡散及び循環し、この拡散及び循環する冷気により温度が分散され、低温化を抑制する。より詳細に述べると、野菜室ファン５３によって野菜室８内の冷気は拡散及び循環され、この拡散及び循環する冷気は、野菜室８の背面に位置する冷却室温度帯域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抑制し、結露発生を防止する。 The low temperature in the vicinity of the lower back of the vegetable room due to this cold radiation is eliminated by diffusing and circulating the cold air in the vegetable room 8 by driving the vegetable room fan 53 both in the cooling operation and when the cooling is stopped. To do. That is, when the above-described vegetable compartment fan 53 is driven, the cold air in the vegetable compartment 8 diffuses and circulates as described above, and the temperature is dispersed by the diffused and circulated cold air, thereby suppressing the temperature reduction. More specifically, the cold air in the vegetable room 8 is diffused and circulated by the vegetable room fan 53, and the diffused and circulated cold air is cooled and radiated from the cooling room temperature zone located at the back of the vegetable room 8. The temperature in the lower part of the back of the vegetable room, which is likely to be lowered by the cold radiation from the freezer compartment 9 is diffused in the vegetable room 8, the temperature in the vegetable room 8 is lowered to cool the vegetable room 8, and at the same time the back of the vegetable room Suppresses the occurrence of extremely low temperatures and temperature differences near the bottom, preventing condensation.
なお、全ての室が設定温度を下回り圧縮機１５及び冷却ファン１９の動作が停止すると、全ての冷気はそれまでの冷却ファン１９により付いていた圧力差を解消し、温度の違いから生じる密度差による平衡状態へ流れ始める。この場合、冷却室冷気搬送路３０に次いで冷凍室９内の圧力が高いため、この冷却室冷気搬送路３０、冷却室１６及び冷凍室９内の冷気は圧力差が解消するまで広がり続ける。このとき、冷凍室９内及び冷却室１６内の冷気は比較的低温で密度が高くこれらの室に溜まっているため、少なくとも冷却室冷気搬送路３０内の冷たい冷気が下方に流下してきて、最も冷たい冷却室１６の高さまで冷気が達することになる。ここで、前記冷却室１６及び冷凍室９内には冷たい冷気が充満しているため、前記流下してくる冷たい冷気は冷却室１６と冷凍室９を介してつながっている冷気の戻り通路３８へと広がり、戻り通路３８を逆流して冷却室１６に溜まる冷気の上端、つまり冷却室１６の上方に開口した冷却ファン１９の下端高さまで達する。 When all the chambers are below the set temperature and the operation of the compressor 15 and the cooling fan 19 is stopped, all the cold air eliminates the pressure difference that has been applied by the cooling fan 19 so far, and the density difference caused by the temperature difference. It begins to flow to the equilibrium state by. In this case, since the pressure in the freezer compartment 9 is high next to the cooler chamber cool air conveyance path 30, the cool air in the cool chamber cool air conveyor path 30, the cooling chamber 16, and the freezer compartment 9 continues to spread until the pressure difference is eliminated. At this time, since the cool air in the freezer compartment 9 and the cooler chamber 16 is relatively low in temperature and has a high density, the cool air in at least the cooler cooler conveyance path 30 has flowed downward, The cold air reaches the height of the cold cooling chamber 16. Here, since the cooling chamber 16 and the freezing chamber 9 are filled with cold cold air, the cold cold air flowing down to the cold air return passage 38 connected to the cooling chamber 16 via the freezing chamber 9. It spreads back and flows back through the return passage 38 and reaches the upper end of the cool air accumulated in the cooling chamber 16, that is, the lower end height of the cooling fan 19 opened above the cooling chamber 16.
本実施の形態では、野菜冷気出入り口４４の下端は冷却ファン１９のベルマウス下端高さよりも高く設置されているため、逆流した冷気が野菜冷気出入り口４４から野菜室８へ流入することも抑制できる。これにより、野菜室８が逆流冷気により局所的に冷却されることを抑制し、野菜室８内の結露や凍結、過冷を防止できるため、保存野菜の劣化を防止することができる。 In the present embodiment, since the lower end of the vegetable cold air inlet / outlet 44 is installed higher than the height of the bell mouth lower end of the cooling fan 19, it is also possible to suppress backflow of cold air from the vegetable cold air inlet / outlet 44 into the vegetable compartment 8. Thereby, it can suppress that the vegetable compartment 8 is locally cooled by backflow cold air, and it can prevent dew condensation, freezing, and overcooling in the vegetable compartment 8, and can prevent deterioration of preserved vegetables.
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。しかも、この冷蔵庫は、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。 As described above, this refrigerator prevents the occurrence of dew condensation due to the local low temperature of the vegetable room 8 during both the cooling operation and the cooling stop, so the cooler 18 for generating cold air is increased in size to the cooling room. Even if 16 is a large large-capacity refrigerator that spans the freezer compartment 9 and the vegetable compartment 8, dew condensation due to cold radiation from the cooling compartment 16 can be suppressed. Therefore, in the refrigerator in the whole area from the small capacity small refrigerator to the large capacity large refrigerator, it is possible to suppress the vegetable deterioration due to the dew condensation water generated by the cold radiation from the cooling chamber 16 and cool and store the vegetables in a good state. It becomes possible. In addition, this refrigerator is a middle vegetable room type refrigerator in which the vegetable room 8 is provided in the upper and lower central parts of the refrigerator body 1 between the refrigerator compartment 7 and the freezer compartment 9, so that condensation occurs as described above. This is effective because it is possible to improve the usability of a user who is mainly used for taking in and out vegetables and the like while preventing and storing the vegetables in a good condition.
以上のようにこの冷蔵庫は野菜室内の温度差に起因する結露発生を抑制すると同時に野菜室内を低温に冷却保持することができ、常に良好な状態で野菜を冷却保存することができるものであるが、更にこの冷蔵庫は野菜室冷却に関してさらに次のような効果も有するので、以下これを説明しておく。 As described above, this refrigerator can suppress the occurrence of condensation due to the temperature difference in the vegetable room, and at the same time can keep the vegetable room cooled to a low temperature, and can always cool and store the vegetables in a good state. Furthermore, since this refrigerator has the following effects regarding the cooling of the vegetable room, this will be described below.
まず、この実施の形態では上記野菜室ファン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。 First, in this embodiment, the vegetable compartment 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. In addition, it is possible to prevent the circulating cold air from entering the lower vegetable storage case 49a and the upper vegetable storage case 49b and flowing between the vegetables, and also preventing the drying deterioration of the vegetables that tend to occur due to the cold air flowing between the vegetables. Thus, the vegetables can be stored in a cool and fresh state.
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 that also serves as a cold air suction port that diffuses or circulates in the vegetable compartment above the vegetable storage case 48 constituted by the lower vegetable storage case 49a and the upper vegetable storage case 49b. Since the second vegetable cold air suction port 51 is provided, the cold air that diffuses or circulates in the vegetable compartment 8 does not enter the vegetable storage case 48 including the lower vegetable storage case 49a and the upper vegetable storage case 49b. It flows to the 1st vegetable cold air suction inlet 47 and the 2nd vegetable cold air suction inlet 51, can prevent the drying deterioration of a vegetable more reliably, and can preserve | save a vegetable in a fresh and favorable state by cooling. The effect of preventing the drying deterioration of the vegetables can be further enhanced by bringing the upper surface opening edge of the upper vegetable storage case 49b closer to the partition plate 5 that also serves as the vegetable room ceiling surface, and if a cover that covers the upper surface opening is provided. Furthermore, it can raise effectively.
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 compartment fan 53 is located below the upper opening edge of the vegetable storage case 48 constituted by the lower vegetable storage case 49a and the upper vegetable storage case 49b, it is blown from the vegetable chamber fan 53. The cold air diffuses or circulates in the vegetable storage case 48, particularly in the vicinity of the bottom surface and lower outer periphery of the lower vegetable storage case 49a. Therefore, the cold air diffused and / or circulated by the vegetable compartment fan 53 is more difficult to enter the vegetable storage case 48, and the dry deterioration of the vegetables caused by the cold air entering and circulating in the vegetable storage case 48 from this point. Can be reliably prevented, and the vegetables can be stored in a cooler and fresher state.
また、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 this embodiment, the vegetable storage case 48 has a lower vegetable storage case 49a that is divided into left and right sides and a non-vegetable storage portion 59 such as a plastic bottle or a pack (hereinafter referred to as a PET bottle storage portion 59). The vegetable room fan 53 is provided on the back side of the vegetable room on the side of the PET bottle storage 59 and the cold air in the vegetable room is diffused or circulated toward the PET bottle storage 59. Therefore, the cool air from the vegetable room fan 53 circulates intensively around the PET bottle storage 59, and efficiently uses the PET bottles and packs stored in the PET bottle storage 59. Can be cooled. In particular, drinking water such as PET bottles and packs stored in the PET bottle storage 59 is effective because it has a larger heat capacity than vegetables and is difficult to cool. It is possible to efficiently suppress the rise, effectively prevent the occurrence of condensation, and at the same time, preserve the vegetables 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。 Particularly in this embodiment, the first vegetable cold air inlet 47 provided in the vegetable compartment 8 together with the vegetable compartment fan 53 is also provided in the portion of the vegetable storage case 48 on the storage portion 59 side such as a plastic bottle. The cold air from the vegetable compartment fan 53 can be circulated more efficiently and intensively 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へとも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。 In addition, since the second vegetable cold air suction port 51 that is also another suction port for circulating the cold air in the vegetable room 8 is provided in the vegetable room fan 53 and the upper part of the vegetable room at a substantially diagonal position, The cold air from the vegetable compartment fan 53 diffuses and circulates through the bottom portion of the container portion 59 of the vegetable storage case 48 forward through the bottom portion 59 of the vegetable storage case 48 while obliquely passing through the vegetable compartment 8 and circulates. So that the cold air can be prevented from entering the vegetable compartment case comprising the lower vegetable storage case 49a and the upper vegetable storage case 49b. Cold air can be diffused or circulated in a wide range around the outer periphery of the vegetable case 49b, and vegetables, plastic bottles and the like can be cooled effectively.
一方、この実施の形態で示す冷蔵庫は、冷却室１６から冷蔵室７への冷蔵冷気の往き通路３７を冷蔵庫本体背面の略中央部に配置するとともに、前記往き通路３７の側方に前記冷蔵室７から冷却室１６への冷蔵冷気の戻り通路３８部分を配置し、かつその冷蔵冷気の戻り通路３８部分の前方に野菜室通路部５０を縦設した構成としてある。これにより、野菜室通路部５０は、風路断面積を小さく設定できる冷蔵冷気の戻り通路３８部分と縦設し、風路断面積を大きく設定する必要のある冷蔵冷気の往き通路３７部分の側方に位置してこれらが前後方向に重なることがないので、その分野菜室８の奥行き寸法を拡大することができ、野菜を良好な状態で冷却保存できることに加えて野菜収納量も多くすることができ、使い勝手の良い冷蔵庫とすることができる。 On the other hand, in the refrigerator shown in this embodiment, the refrigerated cold air going-out passage 37 from the cooling chamber 16 to the refrigerated compartment 7 is disposed at a substantially central portion on the rear surface of the refrigerator main body, and the refrigerated compartment is located on the side of the outgoing passage 37. The refrigerated cold air return passage 38 portion from 7 to the cooling chamber 16 is disposed, and the vegetable compartment passage portion 50 is provided vertically in front of the refrigerated cold air return passage 38 portion. As a result, the vegetable compartment passage 50 is provided vertically with the refrigerated cold air return passage 38 portion where the air passage cross-sectional area can be set small, and the side of the refrigerated cold air outgoing passage 37 portion where the air passage cross-sectional area needs to be set large. Because they do not overlap in the front-rear direction, the depth dimension of the vegetable compartment 8 can be increased accordingly, and the vegetables can be stored in a cool state in addition to increasing the amount of vegetables stored Can be made into a convenient refrigerator.
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３
９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を介し野菜冷気出入り口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。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。
Further, this refrigerator has a communication passage 3 between the refrigerated cold air passage 32 and the refrigerated cold air return passage 33.
9 is formed, and when the vegetable compartment fan 53 rotates, low-temperature fresh cold air in the refrigerated cold air passage 32 is directly mixed into the refrigerated cold air return passage 33 by the suction force, and the vegetable cold air inlet / outlet 44 through the return passage 38. To be fed into the vegetable compartment 8. That is, the vegetable room 8 is cooled by the return cold air having a relatively high temperature after cooling from the cold room 7, but in this refrigerator, the cold air after cooling the cold room is rotated by the rotation of the vegetable room fan 53. The vegetable room 8 is cooled with cold air that has been cooled by mixing low temperature fresh cold air. Therefore, the vegetable compartment 8 can be effectively cooled, and the vegetable compartment 8 is reliably cooled even when the cooling load condition is bad, for example, when many vegetables, plastic bottles, etc. are temporarily stored. be able to. In addition, the amount of low-temperature fresh cold air taken in through the communication passage 39 can be increased by increasing the number of rotations of the vegetable compartment fan 53, and a large amount of room temperature PET bottles having a large heat capacity are stored in summer. Even at times, this can be reliably cooled. Moreover, 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 efficiently suppressed, and the vegetables can be stored in a cooled state in a good 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 is activated when the refrigerator compartment damper 31 is opened by the output from the refrigerator compartment temperature detecting means 65 to cool the refrigerator compartment 7 and the vegetable compartment 8 and diffuses the cold air in the vegetable compartment 8. Or, although it is circulated, in this embodiment, the temperature is controlled based on the temperature detected by the vegetable room temperature detecting means 66 provided in the vegetable room 8. Even when the vegetable compartment 8 is not heated, it begins to rotate when the temperature of the vegetable compartment 8 becomes equal to or higher than the set temperature, and cold air is diffused or circulated in the vegetable compartment 8. Therefore, when the temperature of the vegetable room becomes high and a large temperature difference is caused by the cold radiation from the cooling chamber 16 and the condition is likely to cause dew condensation, the vegetable room fan 53 rotates to eliminate this and effectively generate dew condensation. 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 room 8 becomes higher than the second set temperature set to a temperature slightly higher than the set temperature in spite of the rotation of the vegetable room fan 53, the vegetable room fan The number of rotations of 53 can be increased to increase the diffusion or circulation of the cold air, and the amount of fresh cold air taken in can be increased and the vegetable room 8 can be reliably cooled. Therefore, the lack of cooling in the summer can be resolved, and good cooling storage of vegetables and the like can be reliably realized to increase the reliability of the refrigerator.
（実施の形態２）
図２３は実施の形態２における冷蔵庫の冷却室背面部分の冷気流れを説明する斜視図、図２４は同実施の形態２における冷蔵庫の野菜室における冷気流れを説明するための概略断面図である。
(Embodiment 2)
FIG. 23 is a perspective view for explaining the cold air flow in the rear portion of the cooling chamber of the refrigerator in the second embodiment, and FIG. 24 is a schematic cross-sectional view for explaining the cold air flow in the vegetable room of the refrigerator in the second embodiment.
この実施の形態２の冷蔵庫は、前記実施の形態１で説明した野菜冷気出入り口４４の代わりに野菜冷気入口４５と野菜冷気戻り口４６をそれぞれ別々に設けたものである。すなわち、野菜室８に野菜冷気入口４５と当該野菜冷気入口４５より上方位置、例えば第一の通路４７ａ、第二の通路５１ａと野菜室通路部５０との合流付近に野菜冷気戻り口４６を設けたものである。 In the refrigerator of the second embodiment, a vegetable cold air inlet 45 and a vegetable cold air return port 46 are separately provided in place of the vegetable cold air inlet / outlet 44 described in the first embodiment. That is, the vegetable cold air return port 46 is provided in the vegetable room 8 at a position above the vegetable cold air inlet 45 and the vegetable cold air inlet 45, for example, near the junction of the first passage 47a, the second passage 51a, and the vegetable room passage portion 50. It is a thing.
その他の構成は前記実施の形態１と同様であり、同一構成要素部分には同一番号を附記して説明は省略する。 Other configurations are the same as those in the first embodiment, and the same components are denoted by the same reference numerals and description thereof is omitted.
この実施の形態２の場合は、野菜室内への冷気は野菜冷気入口４５から冷気の戻り通路３８中の冷気が流れ込み、野菜室８内の冷気は野菜冷気戻り口４６から冷気の戻り通路３８へと流出する。したがって、一つの野菜冷気出入り口４４から冷気が出入りする場合に比べ冷気の出入りは円滑で、より多くの冷気が野菜室８内に流れ込むもののとなり、効率よく野菜室内に冷気を取り込んで、野菜室８内を強力に冷却できる。よって、例えば野菜
室８が冷蔵庫本体の最下部にあって野菜室８の底部が外気からの熱輻射を受けて低温化しにくい冷蔵庫のような場合等に効果的である。
In the case of the second embodiment, the cold air into the vegetable room flows from the vegetable cold air inlet 45 to the cold air return passage 38, and the cold air in the vegetable room 8 flows from the vegetable cold air return port 46 to the cold air return passage 38. And leaked. Therefore, compared with the case where cold air enters and exits from one vegetable cold air inlet / outlet 44, the cold air enters and exits smoothly, and more cold air flows into the vegetable room 8, and the cold air is efficiently taken into the vegetable room 8. The inside can be cooled strongly. Therefore, for example, it is effective when the vegetable room 8 is at the lowermost part of the refrigerator body and the bottom of the vegetable room 8 receives heat radiation from the outside air and is not easily cooled.
その他の作用効果は野菜冷気出入り口４４一つで冷気を出入りさせて野菜の乾燥劣化を抑制する効果以外実施の形態１と同様であり、説明は省略する。 Other functions and effects are the same as those in the first embodiment except for the effect of suppressing the deterioration of drying of vegetables by allowing cold air to enter and exit from one vegetable cold air inlet / outlet 44, and a description thereof will be omitted.
なお、上記各実施の形態において、野菜室８背面への冷輻射は、冷却室１６はもちろん冷却室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と称している。 In each of the above embodiments, the cooling radiation to the back of the vegetable compartment 8 is not limited to the cooling compartment 16 but the cooling compartment cool air conveyance path 30 zone to the refrigerator compartment damper 31 on the downstream side of the cooling fan 16 of the cooling compartment 16 is this cooling compartment. 16 is a cooling room temperature region in the same cryogenic temperature zone as that 16 and receives strong cold radiation at a portion facing the cooling room temperature zone up to the refrigerating room damper 31. In the present invention, this cooling room cold air conveyance path The cooling chamber temperature zone including 30 is collectively referred to as the cooling chamber 16.

＜その他の実施形態＞
例えば、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。
<Other embodiments>
For example, in the present embodiment, the vegetable room 8 is described as an example of a middle vegetable type refrigerator in which the vegetable room 8 is provided between the refrigerator room 7 and the freezer room 9, but this is a refrigerator in which the vegetable room 8 is at the bottom. Even so, it is sufficient if the cooling room 16 is installed across the back of the vegetable room 8 and the freezing room 9.
また、この実施の形態では野菜室通路部５０は野菜室８の正面から見て右側部分に設けたものを示したが、これは左側に設けてもよく、この場合は野菜収納ケース４８のペットボトル等収納部はこれに合わせて左側に設定する。 In this embodiment, the vegetable compartment passage 50 is provided on the right side when viewed from the front of the vegetable compartment 8, but this may be provided on the left side. In this case, the vegetable storage case 48 is a pet. The bottle storage part is set on the left side accordingly.
さらに上記野菜室通路部５０は野菜室の右側に偏る位置に設けたが、これは野菜室８の背面左右全域にわたって設けてもよく、この場合はこの野菜室通路部５０がその背面冷却室からの冷輻射を遮断する機能も期待でき、より効果的に結露発生を防止することができる。 Furthermore, although the said vegetable compartment channel | path part 50 was provided in the position biased to the right side of a vegetable compartment, this may be provided over the back left-right whole region of the vegetable compartment 8, and in this case, this vegetable compartment channel | path part 50 is from the back surface cooling chamber. A function of blocking the cold radiation can be expected, and condensation can be prevented more effectively.
さらにまた、この野菜室通路部５０は必ずしも必要とするものではなく、野菜室ファン５３は野菜冷気出入り口４４にその吸込み側に位置するようして野菜室８内に露出状態で設けてもよいものである。 Furthermore, the vegetable compartment passage portion 50 is not necessarily required, and the vegetable compartment fan 53 may be provided in the vegetable compartment 8 in an exposed state so as to be located at the suction side of the vegetable cold air inlet / outlet 44. It is.
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。 The supply / stop of the cold air to the vegetable room 8 is also performed by using the cold room damper 31. However, the supply / stop may be performed by providing a damper dedicated to the vegetable room. Similarly to 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 temperature detecting means 65 and the vegetable room temperature detecting means 66.
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 illustrated what was controlled by the output from the vegetable room temperature detection means 66 provided in the vegetable room 8, this was controlled in conjunction with the output of the refrigerator compartment temperature detection means 65. Alternatively, the rotation may be intermittently repeated for a predetermined time, and may be appropriately selected according to the characteristics of the refrigerator.
また、本実施の形態では野菜収納ケース４８を下段野菜収納ケース４９ａと上段野菜収納ケース４９ｂの複数のケースの組み合わせからなるもので説明したが、これは一つのケースで構成してもよく、野菜収納ケース４８の上部開口とは本実施の形態のように複数のケースの組み合わせの場合は最上段の野菜収納ケースの開口をいうものである。 Further, in the present embodiment, the vegetable storage case 48 is described as a combination of a plurality of cases of the lower vegetable storage case 49a and the upper vegetable storage case 49b. However, this may be configured as a single case. The upper opening of the storage case 48 means the opening of the uppermost vegetable storage case in the case of a combination of a plurality of cases as in the present embodiment.
また、野菜収納ケース４８に形成したペットボトル等の非野菜収納部５９は野菜収納ケース４８内を左右に仕切って形成したが、これば前後方向に仕切ってその前部を非野菜収納部としてもよいものである。 In addition, the non-vegetable storage portion 59 such as a plastic bottle formed in the vegetable storage case 48 is formed by dividing the inside of the vegetable storage case 48 into left and right. It ’s good.
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 was also installed in the upper rear region of the refrigerator main body 1, this is not limited to that described in the embodiment. For example, the compressor 15 is provided in the lower rear of the refrigerator main body 1. It may be.
また、野菜室８内の結露を抑制するために野菜室ファン５３を設けているが、冷蔵庫において結露問題と同程度に大きな課題となる野菜の冷却保存時における乾燥劣化の防止を図るだけであれば必ずしも野菜室ファン５３は必要ではなく、実施の形態１で説明した野菜冷気出入り口４４を一つ設ける構成だけでよいものである。この場合、野菜室８が、冷蔵室７と冷凍室９の間にあって、背部に冷却室１６が位置している真ん中野菜室タイプの冷蔵庫であれば、野菜室８はその周りが外気より低温の状態となっているため、比較的低温の状態に維持されるから、野菜室８内への冷気の出入り口を一つとして野菜室８に供給される冷気量が少なくなっても通常状態では良好な冷却が可能である。 Moreover, although the vegetable compartment fan 53 is provided in order to suppress the dew condensation in the vegetable compartment 8, it is only to aim at prevention of the drying deterioration at the time of the cold preservation of the vegetable which becomes a subject as big as a condensation problem in a refrigerator. For example, the vegetable room fan 53 is not necessarily required, and only the configuration in which one vegetable cold air inlet / outlet 44 described in the first embodiment is provided is sufficient. In this case, if the vegetable compartment 8 is a refrigerator of the middle vegetable compartment type between the refrigerator compartment 7 and the freezer compartment 9 and the cooling compartment 16 is located at the back, the vegetable compartment 8 is cooler than the outside air. Since it is in a state, it is maintained in a relatively low temperature state, so that even if the amount of cold air supplied to the vegetable room 8 is reduced with a single entry / exit of cold air into the vegetable room 8, it is good in the normal state Cooling is possible.
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。 The refrigerator according to the present invention suppresses the occurrence of condensation in the vegetable room even in a refrigerator with a large cooling capacity, can cool and store vegetables in a good state, and is widely applied to refrigerators for business use as well as home use. be able to.
