本開示は、冷蔵庫に関する。
This disclosure relates to a refrigerator.
一般に、冷蔵庫においては、冷蔵庫本体背面の冷却室で冷気が生成され、その冷気が送風機によって冷蔵室、冷凍室、および野菜室等に循環され、各室内の食品が冷却される。この種の冷蔵庫には、冷蔵室への冷気循環量を調整する冷蔵室ダンパに加えて、野菜室への冷気循環量を制御する野菜室ダンパが設けられて、野菜室を効率よく冷却できるようにしたものがある(例えば、特許文献1参照)。
Generally, in a refrigerator, cold air is generated in a cooling chamber on the back of the refrigerator body, and the cold air is circulated to a refrigerator compartment, a freezer compartment, a vegetable compartment, and the like by a blower, and food in each room is cooled. This kind of refrigerator is equipped with a vegetable room damper that controls the amount of cold air circulation to the vegetable room in addition to the cold room damper that adjusts the amount of cold air circulation to the cold room, so that the vegetable room can be cooled efficiently. (For example, refer to Patent Document 1).
図33は、特許文献1に記載された従来の冷蔵庫を示す。図33に示すように、冷蔵庫100において、冷却室101は、冷凍室102の背面に設けられており、冷却室101で冷気が生成される。冷気は、冷蔵室103と冷凍室102との間を仕切る仕切板104に設けられた冷気通路部105と、これにつながる冷蔵室ダクト106を介して、冷蔵室103に供給される。また、冷気は、冷蔵庫100において、冷気通路部105の途中から分岐した野菜室ダクト107を介して、野菜室108に供給される。冷蔵室ダクト106の冷気通路部105への接続部分には、冷蔵室ダンパ109が組み込まれている。仕切板104に形成された冷気通路部105の野菜室ダクト107への分岐部分には、野菜室ダンパ110が組み込まれている。このような構成により、冷蔵室103および野菜室108それぞれの室への冷気供給量を制御することが可能となっている。なお、図33に示す冷蔵庫は、冷却ファン111および冷却器112を有している。
FIG. 33 shows a conventional refrigerator described in Patent Document 1. As shown in FIG. 33, in the refrigerator 100, the cooling chamber 101 is provided on the back surface of the freezing chamber 102, and cold air is generated in the cooling chamber 101. The cold air is supplied to the refrigerating chamber 103 through a cold air passage portion 105 provided in the partition plate 104 that partitions the refrigerating chamber 103 and the freezing chamber 102 and a refrigerating chamber duct 106 connected thereto. In addition, the cold air is supplied to the vegetable compartment 108 via the vegetable compartment duct 107 branched from the middle of the cold air passage portion 105 in the refrigerator 100. A cold room damper 109 is incorporated in a connection portion of the cold room duct 106 to the cold air passage portion 105. A vegetable compartment damper 110 is incorporated in a branch portion of the cold air passage portion 105 formed in the partition plate 104 to the vegetable compartment duct 107. With such a configuration, it is possible to control the amount of cold air supplied to each of the refrigerator compartment 103 and the vegetable compartment 108. Note that the refrigerator illustrated in FIG. 33 includes a cooling fan 111 and a cooler 112.
特許文献1に記載の冷蔵庫によれば、冷蔵室103(図33参照)への冷気供給とは独立して、野菜室108への冷気供給量を制御できる。よって、野菜室108内を冷やしすぎたり、乾燥させたりすることなく、野菜室108内を効果的に冷却することができる利点がある。
According to the refrigerator described in Patent Document 1, the amount of cold air supplied to the vegetable compartment 108 can be controlled independently of the supply of cold air to the refrigerator compartment 103 (see FIG. 33). Therefore, there is an advantage that the inside of the vegetable compartment 108 can be effectively cooled without overcooling or drying the inside of the vegetable compartment 108.
しかしながら、上記のような従来の冷蔵庫の構成では、冷却室101から野菜室108へ供給される冷気は、冷却室101上方の仕切板104の冷気通路部105に設けられた分岐部分まで吹き上げられたのち、冷却室101下方の野菜室108へと供給される。このため、野菜室ダクト107は、その全長が長く、通路抵抗が大きくなる。このような従来の冷蔵庫では、野菜室ダンパ110を開いて、野菜室108を冷却しているときの冷蔵室への冷気循環を含む全体の冷気循環量が低下し、冷却能力が低下するという課題がある。
However, in the configuration of the conventional refrigerator as described above, the cold air supplied from the cooling chamber 101 to the vegetable compartment 108 is blown up to a branch portion provided in the cold air passage portion 105 of the partition plate 104 above the cooling chamber 101. After that, it is supplied to the vegetable room 108 below the cooling room 101. For this reason, the vegetable compartment duct 107 has a long overall length and a large passage resistance. In such a conventional refrigerator, the whole cold air circulation amount including the cold air circulation to the refrigerator compartment when the vegetable compartment damper 110 is opened and the vegetable compartment 108 is cooled is lowered, and the cooling capacity is lowered. There is.
また、一般に、冷蔵庫は、冷蔵庫本体背面の冷却室で冷気が生成され、その冷気が送風機により、冷蔵室、冷凍室、および野菜室等に循環され、各室内の食品が冷却される。この種の冷蔵庫には、冷蔵室への冷気循環量を調整する冷蔵室ダンパとともに、さらに冷凍室への冷気循環量を制御する冷凍室ダンパが設けられて、冷凍室を効率よく冷却できるようにしたものがある(例えば、特許文献2参照)。
In general, in the refrigerator, cold air is generated in the cooling chamber on the back of the refrigerator body, and the cold air is circulated to the refrigerator compartment, freezer compartment, vegetable compartment, etc. by the blower, and the food in each room is cooled.

(For example, refer to Patent Document 2).
図34は、特許文献2に記載された従来の冷蔵庫の縦断面図である。図34に示すように、冷蔵庫200において、冷蔵室201の下方に冷凍室202が設けられ、冷凍室202の後方に冷却室203が設けられている。冷蔵庫200は、冷却室203内に設けられた冷却器204によって生成された冷気を、冷却ファン205によって冷蔵室201および冷凍室202に循環させるよう構成されている。冷凍室202への冷気の冷気吹出し口206には、冷凍室ダンパ207が設けられている。冷蔵庫200は、冷凍室ダンパ207により、冷却室203から冷凍室202への冷気供給量を制御できるよう構成されている。
FIG. 34 is a longitudinal sectional view of a conventional refrigerator described in Patent Document 2. As shown in FIG. 34, in the refrigerator 200, a freezer compartment 202 is provided below the refrigerating compartment 201, and a cooling compartment 203 is provided behind the freezer compartment 202. The refrigerator 200 is configured to circulate cold air generated by a cooler 204 provided in the cooling chamber 203 to the refrigerator compartment 201 and the freezer compartment 202 by a cooling fan 205. A freezer compartment damper 207 is provided at the cold air outlet 206 for the cold air to the freezer compartment 202. The refrigerator 200 is configured so that the amount of cold air supplied from the cooling chamber 203 to the freezing chamber 202 can be controlled by the freezing chamber damper 207.
特許文献2に記載されたような従来の冷蔵庫200によれば、冷凍室202への冷気供給量を制御できるので、冷凍食品を効率よく冷凍保存できる利点がある。
According to the conventional refrigerator 200 as described in Patent Document 2, since the amount of cold air supplied to the freezer compartment 202 can be controlled, there is an advantage that frozen food can be efficiently frozen and stored.
しかしながら、上記のような従来の冷蔵庫200は、冷却器204の除霜運転時、除霜した後の高湿の暖冷気がドラフトによって冷却室203を上昇して冷気吹出し口206まで到達し、これが冷凍室ダンパ207に触れて結露する。この結露した水滴は、除霜運転終了後の冷却運転再開時に氷結して、ダンパの動作不良を引き起こす虞がある。
However, in the conventional refrigerator 200 as described above, during the defrosting operation of the cooler 204, the high-humidity warm air after defrosting rises up the cooling chamber 203 by the draft and reaches the cold air outlet 206, which is Condensation occurs when the freezer damper 207 is touched. The condensed water droplets are frozen when the cooling operation is resumed after the defrosting operation is completed, and the damper may malfunction.
このため、このような従来の冷蔵庫200では、氷結を防止するために、冷凍室ダンパ207に氷結防止専用のヒータを設けなくてはならず、構成が複雑化し、コストアップするという課題がある。
For this reason, in such a conventional refrigerator 200, in order to prevent freezing, a heater dedicated to preventing freezing must be provided in the freezer damper 207, and there is a problem that the configuration becomes complicated and the cost increases.
また、一般に、冷蔵庫は、冷蔵庫本体の背面側に設けられた冷却室で冷気が生成され、その冷気が冷却ファンにより冷蔵室に循環され、冷蔵室内の食品が冷却される。この種の冷蔵庫では、冷蔵室に供給される冷気の量は、ダンパで制御されるように構成されている。ダンパは、冷蔵室の背面に設けられた冷蔵室ダクトの下部に組み込まれている(例えば、特許文献3参照)。
In general, in the refrigerator, cold air is generated in a cooling chamber provided on the back side of the refrigerator main body, and the cold air is circulated to the refrigerator compartment by a cooling fan to cool food in the refrigerator compartment. In this type of refrigerator, the amount of cold air supplied to the refrigerator compartment is controlled by a damper. The damper is built in the lower part of the refrigerator compartment duct provided in the back of the refrigerator compartment (for example, refer patent document 3).
図35は、特許文献3に記載された従来の冷蔵庫の冷蔵室ダクトの構成を示している。図35において、冷蔵室ダクト300は、発泡スチロール等の断熱材からなるダクト部材301と、その表面を覆う樹脂製のダクトカバー302とからなる。ダクト部材301に形成されている通路部303の下部に、冷蔵室ダンパ304が組み込まれている。冷蔵室ダンパ304は、ダンパカバー305で覆われ、冷蔵室背面壁にシール部材306を介して装着されている。
FIG. 35 shows a configuration of a refrigerator compartment duct of a conventional refrigerator described in Patent Document 3. 35, the refrigerator compartment duct 300 includes a duct member 301 made of a heat insulating material such as polystyrene foam, and a resin duct cover 302 covering the surface thereof. A refrigerator compartment damper 304 is incorporated in a lower portion of the passage portion 303 formed in the duct member 301. The refrigerator compartment damper 304 is covered with a damper cover 305 and attached to the rear wall of the refrigerator compartment via a seal member 306.
特許文献3に記載されたような従来の冷蔵庫の冷蔵室ダクト300によれば、シール部材306を介して冷蔵室内の冷気が通路部303内に漏れ、結露する場合がある。このため、最近では、冷蔵室ダクトは、ダクト部材301の背面、すなわち冷蔵室背面壁側に、断熱シートを貼り付けて通路部303を覆い、冷蔵室内から冷気が漏れたとしても、漏れた冷気が通路部303内に侵入しないように構成されている。
According to the conventional refrigerator refrigerating room duct 300 described in Patent Document 3, cold air in the refrigerating room may leak into the passage portion 303 through the seal member 306 and may be condensed. For this reason, recently, even if the cold room leaks from the cold room, the cold room duct is covered with the heat insulating sheet on the back surface of the duct member 301, that is, on the rear wall side of the cold room. Is configured not to enter the passage portion 303.
しかしながら、このように構成された冷蔵室ダクトにおいては、冷蔵室内から漏れた冷気は、通路部303を覆った断熱シートの背面側に回り込んで結露する。この結露が場合によっては垂れ落ちて、ダンパカバー305とダクト部材301との接合部から冷蔵室ダンパ304の部分に侵入し、ダンパ動作に支障をきたす等、信頼性を損なうという課題がある。
However, in the refrigerating room duct configured as described above, the cold air leaking from the refrigerating room wraps around the back side of the heat insulating sheet covering the passage portion 303 and is condensed. There is a problem that reliability is deteriorated, for example, the condensation may drop depending on the case and enter a portion of the refrigerator compartment damper 304 from a joint portion between the damper cover 305 and the duct member 301 to hinder the damper operation.
また、一般に、冷蔵庫は、冷蔵室、冷凍室、および野菜室に加えて、冷却温度帯を冷凍温度帯から冷蔵温度帯まで切り換えられる切替室等の貯蔵室が設けられたものがある(例えば、特許文献4参照)。
In general, a refrigerator is provided with a storage room such as a switching room in which a cooling temperature zone can be switched from a freezing temperature zone to a refrigeration temperature zone in addition to a freezing room, a freezing room, and a vegetable room (for example, (See Patent Document 4).
図36は、特許文献4に記載された従来の冷蔵庫を示す。図36に示すように、従来の冷蔵庫400には、冷蔵室401、冷凍室402、および野菜室403とともに、切替室となる貯蔵室404およびその横に位置する製氷室(図示せず)が設けられている。冷蔵庫400には、冷却室405が、冷凍室402の後方に位置するように設けられ、冷却室405内には、冷却器406および冷却ファン407が設けられている。
FIG. 36 shows a conventional refrigerator described in Patent Document 4. As shown in FIG. 36, a conventional refrigerator 400 is provided with a refrigerating room 401, a freezing room 402, and a vegetable room 403, a storage room 404 serving as a switching room, and an ice making room (not shown) located beside the room. It has been. In the refrigerator 400, a cooling chamber 405 is provided so as to be located behind the freezing chamber 402, and in the cooling chamber 405, a cooler 406 and a cooling fan 407 are provided.
貯蔵室404および製氷室には、これらの後方に位置する冷却ファン407によって、各室に冷気が供給される。
Cooling air is supplied to the storage chamber 404 and the ice making chamber by a cooling fan 407 located behind them.
特許文献4に記載されているような従来の冷蔵庫400によれば、冷蔵温度帯から冷凍温度帯まで切り換えられる切替室のような貯蔵室404を備えているので、使い勝手が良い。
According to the conventional refrigerator 400 as described in Patent Document 4, since the storage room 404 such as a switching room that can be switched from the refrigeration temperature zone to the freezing temperature zone is provided, it is easy to use.
しかしながら、特許文献4に記載されているような従来の冷蔵庫400は、冷却ファン407が貯蔵室404とともに、その横に並設された製氷室にも冷気を供給する構成となっている。このため、冷却ファン407は、貯蔵室404のセンターから製氷室側に偏ったところに配置される。したがって、冷却ファン406からの冷気は、貯蔵室404の製氷室側に多く供給され、冷却ムラが生じるという課題がある。
However, the conventional refrigerator 400 as described in Patent Document 4 is configured such that the cooling fan 407 supplies cold air to the ice making chambers arranged side by side along with the storage chamber 404. For this reason, the cooling fan 407 is disposed at a location deviated from the center of the storage chamber 404 toward the ice making chamber. Therefore, a large amount of cold air from the cooling fan 406 is supplied to the ice making chamber side of the storage chamber 404, and there is a problem that uneven cooling occurs.
本開示は、上記のような従来の課題に鑑みてなされたもので、野菜室ダクトの全長を短くして、冷気循環量の低下を抑制すると同時に、野菜室ダクトの全長を短くしたことによって生じる、冷凍室容積の減少が抑制された冷蔵庫を提供する。
This indication is made in view of the above conventional subjects, and arises by shortening the full length of a vegetable compartment duct while shortening the full length of a vegetable compartment duct and suppressing the fall of the amount of cold air circulation. Provided is a refrigerator in which a decrease in freezer volume is suppressed.
具体的には、本開示の一例による冷蔵庫は、冷蔵庫本体、並びに、冷蔵庫本体に設けられた、冷蔵室、冷凍室および野菜室を備える。また、本開示の一例による冷蔵庫は、冷蔵室、冷凍室および野菜室それぞれに供給される冷気を生成する冷却室を備える。また、本開示の一例による冷蔵庫は、冷却室からの冷気を冷蔵室へと案内する冷蔵室ダクトと、冷却室からの冷気を野菜室へと案内する野菜室ダクトとを備える。本開示の一例による冷蔵庫において、冷却室は、冷凍室の後方に設けられている。また、野菜室ダクトには、野菜室ダンパが組み込まれている。また、野菜室ダクトの側部に、野菜室ダンパの駆動用モータが配置されている。また、野菜室ダクト内にダンパフラップが配置されている。
Specifically, a refrigerator according to an example of the present disclosure includes a refrigerator body and a refrigerator room, a freezer room, and a vegetable room provided in the refrigerator body. Moreover, the refrigerator by an example of this indication is provided with the cooling room which produces | generates the cool air supplied to a refrigerator compartment, a freezer compartment, and each vegetable compartment. Moreover, the refrigerator by an example of this indication is provided with the refrigerator compartment duct which guides the cold air from a cooling chamber to a refrigerator compartment, and the vegetable compartment duct which guides the cold air from a cooling chamber to a vegetable compartment. In the refrigerator according to an example of the present disclosure, the cooling chamber is provided behind the freezing chamber. A vegetable room damper is incorporated in the vegetable room duct. Moreover, the drive motor of the vegetable compartment damper is arrange | positioned at the side part of the vegetable compartment duct. A damper flap is disposed in the vegetable compartment duct.
このような構成により、野菜室ダクトは、冷却室上方の冷蔵室と冷凍室との間を仕切る仕切板部分を貫通経由することがなくなる。よって、その分だけダクト長さを短く、かつ、通路抵抗を少なくすることができる。これにより、冷気循環量を多くして冷却性能を向上させることができる。
With such a configuration, the vegetable compartment duct does not pass through the partition plate portion that partitions the refrigerator compartment and freezer compartment above the cooling compartment. Therefore, the duct length can be shortened by that amount, and the passage resistance can be reduced. Thereby, the amount of cold air circulation can be increased and the cooling performance can be improved.
また、ダクト長さを短くすべく冷凍室の背面投影面積範囲内で野菜室ダクトを冷却室に接続させていることにより、野菜室ダンパが冷凍室の背面投影面積範囲内に位置する。また、野菜室ダクトの野菜室ダンパ組み込み部分が冷凍室側に突出する構成となっても、野菜室ダクトは、その駆動用モータが野菜室ダクトの側部に設けられており、ダンパフラップが野菜室ダクトの前部或いは後部に設けられているので、冷凍室側に面する野菜室ダンパの前部の壁厚は、ダンパフラップを設けるだけの薄いものでよい。よって、このような構成により、野菜室ダクトの野菜室ダンパ組み込み部分の冷凍室への突出を抑制することができる。したがって、その分だけ、冷凍室の内容積を確保し、冷凍室に設けられる冷凍室容器の奥行き寸法、すなわち冷凍室容量を大きくすることができる。
Also, the vegetable room damper is positioned within the rear projection area range of the freezer compartment by connecting the vegetable room duct to the cooling room within the rear projection area range of the freezer room in order to shorten the duct length. Even if the vegetable room damper built-in portion of the vegetable room duct protrudes to the freezer room side, the vegetable room duct has its drive motor provided on the side of the vegetable room duct, and the damper flap is Since it is provided in the front part or the rear part of the chamber duct, the wall thickness of the front part of the vegetable compartment damper facing the freezer compartment side may be thin enough to provide a damper flap. Therefore, by such a structure, the protrusion to the freezer compartment of the vegetable compartment damper incorporating part of the vegetable compartment duct can be suppressed. Therefore, the internal volume of the freezer compartment can be ensured by that much, and the depth dimension of the freezer compartment provided in the freezer compartment, that is, the freezer compartment capacity can be increased.
また、本開示の一例による冷蔵庫において、野菜室ダンパは、野菜室ダクトに組み込まれて、野菜室ダクトとともに、冷凍室の背面投影面積範囲内に位置するように構成されていてもよい。
Also, in the refrigerator according to an example of the present disclosure, the vegetable room damper may be configured so as to be incorporated in the vegetable room duct and to be located within the rear projection area range of the freezer room together with the vegetable room duct.
このような構成により、野菜室ダンパは、野菜室ダクトを設置するだけで冷蔵庫本体への組み込みができる。すなわち、野菜室ダンパを、野菜室ダクトとは別の場所、例えば冷蔵室と冷凍室との間を仕切る仕切板に別途組み込むような場合に比べ、その生産性を大幅に向上させることができる。
With this configuration, the vegetable compartment damper can be incorporated into the refrigerator body simply by installing the vegetable compartment duct. That is, the productivity of the vegetable compartment damper can be greatly improved as compared with a case where the vegetable compartment damper is separately incorporated in a partition separate from the vegetable compartment duct, for example, a partition plate separating the refrigerator compartment and the freezer compartment.
また、本開示の一例による冷蔵庫において、冷却室は、冷却器と、冷却室の上方に位置する冷却ファンとを備えていてもよい。また、本開示の一例による冷蔵庫において、野菜室ダンパは、冷却器上方の冷却ファンとオーバーラップする高さ位置に設けられていてもよい。
Further, in the refrigerator according to an example of the present disclosure, the cooling chamber may include a cooler and a cooling fan positioned above the cooling chamber. In the refrigerator according to an example of the present disclosure, the vegetable compartment damper may be provided at a height position that overlaps with the cooling fan above the cooler.

以上のように構成された冷蔵庫500について、以下、冷気の流れを中心にその動作および作用効果を説明する。
Hereinafter, the operation and effects of the refrigerator 500 configured as described above will be described focusing on the flow of cold air.
まず、冷却室23から、冷蔵室14および野菜室17への冷気の流れについて説明する。
First, the flow of cold air from the cooling chamber 23 to the refrigerator compartment 14 and the vegetable compartment 17 will be described.
冷蔵庫500において、冷蔵室14の温度が設定温度より高くなると、圧縮機27および冷却ファン25が駆動され、冷却器24で生成された冷気が、冷却ファン25の下流側に供給される。
In the refrigerator 500, when the temperature of the refrigerator compartment 14 becomes higher than the set temperature, the compressor 27 and the cooling fan 25 are driven, and the cold air generated by the cooler 24 is supplied to the downstream side of the cooling fan 25.
冷却ファン25の下流側に供給された冷気は、冷却ファン25の下流側の上部上面に開口する第1冷気供給口33より、冷蔵室ダンパ37を介して、冷蔵室ダクト28に供給される。また、冷気は、冷蔵室ダクト28の左右両側面部に開口する冷気吹出し口(図示せず)から冷蔵室14に吹き出され、冷蔵室14内を冷却する。
The cold air supplied to the downstream side of the cooling fan 25 is supplied to the cold room duct 28 from the first cold air supply port 33 opened on the upper upper surface on the downstream side of the cooling fan 25 via the cold room damper 37. In addition, the cold air is blown out to the refrigerator room 14 from the cold air outlets (not shown) opened in the left and right side surfaces of the refrigerator compartment duct 28 to cool the inside of the refrigerator compartment 14.
また、冷却ファン25の下流側に供給された冷気は、冷却ファン25の下流側の上部側面に開口する第2冷気供給口34より、野菜室ダンパ75を介して、野菜室ダクト30にも供給され、野菜室ダクト30の下端開口から野菜室17に供給され、野菜室17内を冷却する。
Further, the cold air supplied to the downstream side of the cooling fan 25 is also supplied to the vegetable compartment duct 30 through the vegetable compartment damper 75 from the second cold air supply port 34 opened on the upper side surface on the downstream side of the cooling fan 25. Then, the vegetable compartment 17 is supplied from the lower end opening of the vegetable compartment duct 30 to cool the inside of the vegetable compartment 17.
冷蔵室14より冷却温度が高く設定されている野菜室17の温度が設定温度になると、野菜室ダンパ75が閉じられ、野菜室17への冷気供給が停止され、野菜室17が設定温度に保たれる。
When the temperature of the vegetable compartment 17 set higher than the refrigerator compartment 14 reaches the preset temperature, the vegetable compartment damper 75 is closed, the supply of cold air to the vegetable compartment 17 is stopped, and the vegetable compartment 17 is kept at the preset temperature. Be drunk.
この時、本実施の形態の冷蔵庫500は、野菜室17に冷気を供給する第2冷気供給口34と、冷蔵室14に冷気を供給する第1冷気供給口33とが、冷却室23に対し、別個に独立して設けられて、冷却室23から直接、冷蔵室ダクト28および野菜室ダクト30それぞれへと冷気が独立して供給されるように構成されている。このような構成により、野菜室ダンパ75が閉じられても、冷蔵室ダクト28へと供給される冷気の量は変化せず、野菜室ダンパ75が開いているときと同じ量が供給される。
At this time, in the refrigerator 500 of the present embodiment, the second cold air supply port 34 that supplies cold air to the vegetable compartment 17 and the first cold air supply port 33 that supplies cold air to the refrigerator compartment 14 are provided to the cooling chamber 23. These are provided separately and independently so that the cool air is independently supplied directly from the cooling chamber 23 to the refrigerator compartment duct 28 and the vegetable compartment duct 30. With such a configuration, even if the vegetable compartment damper 75 is closed, the amount of cold air supplied to the refrigerator compartment duct 28 does not change, and the same amount as when the vegetable compartment damper 75 is open is supplied.
したがって、冷蔵室14の冷却は、野菜室17に冷気を供給しているときと同じレベルで行われることができ、野菜室ダンパ75の開閉に影響されることなく、安定的に冷却が行われることが可能となる。
Therefore, the cooling of the refrigerator compartment 14 can be performed at the same level as when the cold air is supplied to the vegetable compartment 17, and the cooling is stably performed without being affected by the opening and closing of the vegetable compartment damper 75. It becomes possible.
また、野菜室ダクト30は、冷却室23の冷却ファン25の下流側に直接接続されることにより、冷却室23の前方に位置する第一冷凍室18の背面投影面積範囲内で、冷却室23に接続されるよう構成されている。このような構成により、野菜室ダクト30は、冷却室23上方の冷蔵室14と、第一冷凍室18との間を仕切る仕切板5部分を貫通経由することがないので、その分だけダクト長さを短く、かつ、通路抵抗を少なくすることができる。
Further, the vegetable compartment duct 30 is directly connected to the downstream side of the cooling fan 25 of the cooling chamber 23, so that the cooling chamber 23 is within the rear projection area range of the first freezer compartment 18 positioned in front of the cooling chamber 23. Configured to be connected to. With such a configuration, the vegetable compartment duct 30 does not pass through the partition plate 5 that partitions the refrigerator compartment 14 above the cooling compartment 23 and the first freezer compartment 18, so that the duct length is increased accordingly. The length can be shortened and the passage resistance can be reduced.
よって、このような構成により、野菜室ダクト30および冷蔵室ダクト28等を介して、冷却ファン25によって循環させる冷蔵庫500全体の冷気循環量を増加させることができる。したがって、冷気循環量が増加した分だけ、冷却性能を向上させることができる。
Therefore, with such a configuration, it is possible to increase the amount of cold air circulating in the entire refrigerator 500 that is circulated by the cooling fan 25 through the vegetable compartment duct 30 and the refrigerator compartment duct 28 and the like. Therefore, the cooling performance can be improved by an amount corresponding to the increase in the amount of cool air circulation.
ここで、野菜室ダクト30の長さを短くすべく、第一冷凍室18の背面投影面積範囲内で野菜室ダクト30を冷却室に接続させていることにより、野菜室ダンパ75が、第一冷凍室18の背面投影面積範囲内に位置して、野菜室ダクト30の野菜室ダンパ組み込み部分が第二冷凍室15側に突出する形となる。
Here, in order to shorten the length of the vegetable compartment duct 30, the vegetable compartment damper 75 is connected to the cooling compartment within the rear projection area range of the first freezer compartment 18, so that the vegetable compartment damper 75 It is located within the rear projection area range of the freezer compartment 18, and the vegetable compartment damper built-in portion of the vegetable compartment duct 30 projects to the second freezer compartment 15 side.
しかしながら、本実施の形態では、野菜室ダンパ75は、野菜ダンパ駆動用モータ76が野菜室ダクト30の側部に設けられ、ダンパフラップ75aが野菜室ダクト30の前部に設けられている。したがって、第二冷凍室15側に面する野菜室ダンパ75の前部の壁厚は、薄板からなるダンパフラップ75aを位置させるだけの薄いもので形成することができ、第二冷凍室15への突出を抑制することができる。その結果、その分だけ、第二冷凍室15の内容積を確保し、冷凍室容器62の奥行き寸法を大きくすることができる。
However, in the present embodiment, in the vegetable compartment damper 75, the vegetable damper drive motor 76 is provided on the side portion of the vegetable compartment duct 30, and the damper flap 75a is provided on the front portion of the vegetable compartment duct 30. Therefore, the wall thickness of the front part of the vegetable compartment damper 75 facing the second freezer compartment 15 side can be formed by a thin one that only positions the damper flap 75a made of a thin plate. Protrusion can be suppressed. As a result, the internal volume of the second freezer compartment 15 can be secured by that much, and the depth dimension of the freezer compartment 62 can be increased.
また、野菜室ダンパ75は、冷却室23の冷却ファン25とオーバーラップする高さ位置に設けられている。このような構成により、上述した冷却性能向上効果を生かしつつ、動作不良を防止して冷蔵庫500の信頼性を確保することができる。
Further, the vegetable room damper 75 is provided at a height position overlapping with the cooling fan 25 of the cooling room 23. With such a configuration, it is possible to prevent malfunctions and ensure the reliability of the refrigerator 500 while taking advantage of the above-described cooling performance improvement effect.
すなわち、野菜室17は、比較的高い温度に設定され、湿度も高い状態となっているため、野菜室ダンパ75が閉じられて冷気循環が停止している時、この湿度の高い暖冷気が野菜室17内から野菜室ダクト30内へと逆流する場合がある。この湿度の高い暖冷気が野菜室ダンパ75に触れると湿気が結露し、この結露した結露水が野菜室17の冷却再開時、野菜室17へと供給される冷気によって氷結し、野菜室ダンパ75が開閉不良となる場合がある。
That is, since the vegetable room 17 is set to a relatively high temperature and has a high humidity, when the vegetable room damper 75 is closed and the cold air circulation is stopped, the hot and cold air with high humidity is the vegetable. There is a case where the gas flows backward from the chamber 17 into the vegetable chamber duct 30. When this hot and cold air with high humidity touches the vegetable room damper 75, moisture is condensed, and when the cooling of the vegetable room 17 is resumed, the condensed water is frozen by the cold air supplied to the vegetable room 17. May result in poor opening and closing.
しかしながら、本実施の形態の冷蔵庫500では、野菜室ダンパ75が冷却ファン25とオーバーラップする高さ位置に設けられているため、その分、野菜室17から野菜室ダンパ75までの距離を確保でき、冷却器24の高さ寸法分だけ、上方へと離すことができる。したがって、冷気循環停止時に、野菜室17内の湿度の高い暖冷気が、野菜室ダクト30内で上昇して、野菜室ダンパ75に達し、これが結露することを抑制することができる。
However, in the refrigerator 500 of the present embodiment, since the vegetable compartment damper 75 is provided at a height position that overlaps the cooling fan 25, the distance from the vegetable compartment 17 to the vegetable compartment damper 75 can be secured accordingly. The height of the cooler 24 can be separated upward. Therefore, when the cold air circulation is stopped, it is possible to prevent the hot and cold air having high humidity in the vegetable compartment 17 from rising in the vegetable compartment duct 30 and reaching the vegetable compartment damper 75, which is condensed.
よって、このような構成により、野菜室17への冷気循環再開時に野菜室ダンパ75が氷結して動作不良を起こすことを防止でき、信頼性を確保することができる。
Therefore, with such a configuration, it is possible to prevent the vegetable room damper 75 from freezing and causing malfunction when the cold air circulation to the vegetable room 17 is resumed, and to ensure reliability.
つまり、本実施の形態の冷蔵庫500のように、野菜室ダクト30が、冷却室23前方に位置する第一冷凍室18の背面投影面積範囲内で冷却室23に接続され、かつ、野菜室ダンパ75が、冷却ファン25とオーバーラップする高さ位置に組み込まれることによって、冷却性能を向上させつつ、野菜室ダンパ75の動作不良を抑制して信頼性を確保することができる。更には、第二冷凍室15の容積も確保することができる。
That is, like the refrigerator 500 of the present embodiment, the vegetable compartment duct 30 is connected to the cooling compartment 23 within the rear projection area range of the first freezing compartment 18 located in front of the cooling compartment 23, and the vegetable compartment damper. 75 is incorporated at a height position that overlaps with the cooling fan 25, thereby improving the cooling performance and suppressing malfunction of the vegetable compartment damper 75 to ensure reliability. Furthermore, the volume of the second freezer compartment 15 can be secured.
更に、本実施の形態の冷蔵庫500では、野菜室ダクト30は、冷蔵室14から冷却室23への冷蔵室戻りダクト58に、前後方向に重ね合わされて配置されている。また、本実施の形態の冷蔵庫500では、野菜室ダクト30および冷蔵室戻りダクト58は、発泡スチロール等の弾性を有する材料で形成され、野菜室ダクト30と冷蔵室戻りダクト58とで野菜室ダンパ75が挟持されている。このような構成により、生産性が更に向上する利点がある。
Furthermore, in the refrigerator 500 of the present embodiment, the vegetable compartment duct 30 is disposed so as to overlap the refrigeration compartment return duct 58 from the refrigeration compartment 14 to the cooling compartment 23 in the front-rear direction. Moreover, in the refrigerator 500 of this Embodiment, the vegetable compartment duct 30 and the refrigerator compartment return duct 58 are formed with elastic materials, such as a polystyrene foam, and the vegetable compartment damper 75 is comprised by the vegetable compartment duct 30 and the refrigerator compartment return duct 58. Is pinched. With such a configuration, there is an advantage that productivity is further improved.
詳述すると、野菜室ダンパ75は、野菜室ダクト30と冷蔵室戻りダクト58とで挟持されているから(図20参照)、まず、冷蔵庫本体1外で、野菜室ダクト30と冷蔵室戻りダクト58とを組み付ける。そして、野菜室ダンパ75を野菜室ダクト30に隣接する冷却器カバー31とともに冷凍室カバー32で前面を覆い、野菜室ダンパ75を冷蔵室戻りダクト58との間に組み込んでおく。野菜室ダンパ75が組み込まれた野菜室ダクト30と冷蔵室戻りダクト58とのセット物を、冷却室23の横に組み込むだけで、野菜室ダクト30の冷蔵庫本体1への組み込みができ、生産性を向上させることができる。
More specifically, the vegetable room damper 75 is sandwiched between the vegetable room duct 30 and the refrigerated room return duct 58 (see FIG. 20). First, outside the refrigerator body 1, the vegetable room duct 30 and the refrigerated room return duct. 58 is assembled. Then, the front of the vegetable compartment damper 75 is covered with the freezer compartment cover 32 together with the cooler cover 31 adjacent to the vegetable compartment duct 30, and the vegetable compartment damper 75 is assembled between the refrigeration compartment return duct 58. By simply assembling the set of the vegetable room duct 30 with the vegetable room damper 75 and the refrigeration room return duct 58 next to the cooling room 23, the vegetable room duct 30 can be incorporated into the refrigerator main body 1 and productivity is increased. Can be improved.
しかも、野菜室ダクト30および冷蔵室戻りダクト58は、何れも発泡スチロールで形成されていて弾性力を有する。よって、野菜室ダクト30および冷蔵室戻りダクト58が持つ弾性力により、シール部材等を用いることなく、野菜室ダンパ75を気密状態で冷却器カバー31内で野菜室ダクト30に組み込むことができる。したがって、従来のように、野菜室ダンパを仕切板に組み込む場合のように、別途気密性確保のためのシール部材等を用いる必要がなくなり、構成の簡素化および工程の短縮が可能となり、更なる生産性の向上を実現することができる。
Moreover, both the vegetable compartment duct 30 and the refrigeration compartment return duct 58 are made of styrene foam and have elasticity. Therefore, the vegetable compartment damper 75 can be incorporated in the vegetable compartment duct 30 in the cooler cover 31 in an airtight state without using a seal member or the like due to the elastic force of the vegetable compartment duct 30 and the refrigerator compartment return duct 58. Therefore, unlike the conventional case where the vegetable compartment damper is incorporated into the partition plate, it is not necessary to separately use a sealing member for ensuring airtightness, and the configuration can be simplified and the process can be shortened. Productivity can be improved.
加えて、野菜室ダンパ75は、野菜室ダクト30と冷蔵室戻りダクト58とによって弾性支持されることになるので、開閉動作時等に生じがちな微振動による騒音発生をも抑制することができ、静穏性の高い冷蔵庫を得ることができる。
In addition, since the vegetable compartment damper 75 is elastically supported by the vegetable compartment duct 30 and the refrigeration compartment return duct 58, it is possible to suppress the generation of noise due to micro vibrations that tend to occur during opening and closing operations. You can get a quieter refrigerator.
次に、冷蔵室14の冷却動作について説明する。
Next, the cooling operation of the refrigerator compartment 14 will be described.
冷蔵室14は、上述した通り、冷蔵室ダクト28を介して冷気が供給され冷却される。この時、冷蔵室ダクト28に供給された冷気の一部が、冷蔵室14下部に設けられたチルド室22にも供給されチルド室22が冷却される。
The cold room 14 is cooled by supplying cold air through the cold room duct 28 as described above. At this time, a part of the cold air supplied to the refrigerator compartment duct 28 is also supplied to the chilled chamber 22 provided at the lower part of the refrigerator compartment 14 to cool the chilled chamber 22.
冷蔵室14およびチルド室22の冷却は、冷蔵室温度センサ59からの出力に基づき動作する冷蔵室ダンパ37の開閉によって制御され、設定温度に維持される。
The cooling of the refrigerator compartment 14 and the chilled compartment 22 is controlled by opening and closing the refrigerator compartment damper 37 that operates based on the output from the refrigerator compartment temperature sensor 59, and is maintained at the set temperature.
この時、冷蔵庫500では、上述したように、野菜室17の冷却を制御すべく、野菜室ダンパ75が開閉されても、冷蔵室14に供給される冷気量が変化せず一定量で安定する。したがって、高い制御精度を必要とするチルド室22の温度を所望通り高い精度で制御でき、維持できる。これによって、冷蔵庫500におけるチルド室22および他の各室での食材の保存品質を高めることができる。
At this time, in the refrigerator 500, as described above, even if the vegetable compartment damper 75 is opened and closed to control the cooling of the vegetable compartment 17, the amount of cold air supplied to the refrigerator compartment 14 does not change and is stabilized at a constant amount. . Therefore, the temperature of the chilled chamber 22 requiring high control accuracy can be controlled and maintained with high accuracy as desired. Thereby, the preservation | save quality of the foodstuff in the chilled room 22 and other each room in the refrigerator 500 can be improved.
また、ダクト部材28aの冷蔵室14側の表面を覆うダクトカバー28bの左右両側部には、ダクトカバー28bと一体形成され、左右両端部から左右両側に延出する延出リブ28bbが設けられている。このような構成により、前方から直接、冷蔵室ダクト28の前面側部の側面吐出口28dが視認されにくく、冷蔵室14内の意匠性を高めることができる。
Further, on both the left and right sides of the duct cover 28b covering the surface of the duct member 28a on the refrigerator compartment 14 side, extending ribs 28bb are formed integrally with the duct cover 28b and extend from the left and right ends to the left and right sides. Yes. With such a configuration, the side discharge port 28d on the front side portion of the refrigerator compartment duct 28 is hardly visible directly from the front, and the design in the refrigerator compartment 14 can be enhanced.
また、側面吐出口28dの下面は、側面吐出口28dから吐出する冷気の流れが上方に流れるように、傾斜面を有する。このような構成により、下方から流れ出る冷気の渦流発生による風路抵抗を低減することができ、さらに冷蔵室14の冷却性能を高めることができる。
Also, the lower surface of the side discharge port 28d has an inclined surface so that the flow of cool air discharged from the side discharge port 28d flows upward. With such a configuration, it is possible to reduce the air path resistance due to the vortex generation of the cold air flowing out from below, and to further improve the cooling performance of the refrigerator compartment 14.
一方、冷蔵室ダクト28は、通路部21を流れる冷気による冷却作用で、通路部21を覆う断熱シート38の背面に結露が生じ、この結露が垂れ落ちてくることがある。
On the other hand, the refrigerator compartment duct 28 is cooled by the cold air flowing through the passage portion 21, so that condensation occurs on the back surface of the heat insulating sheet 38 that covers the passage portion 21, and this condensation may hang down.
しかしながら、本実施の形態の冷蔵庫500では、図11に示すように、通路部21を覆う断熱シート38の背面の冷蔵室ダンパ37設置部分の上方部に、排水用部材40が設けられている。したがって、垂れ落ちてくる結露水は、排水用部材40によって受け止められ、冷蔵室ダンパ37設置部分以外の部分、本実施の形態では、冷蔵室ダクト28に隣接して設けられた冷蔵室戻りダクト58(図4参照)に向けて排水される。
However, in the refrigerator 500 of the present embodiment, as shown in FIG. 11, the drainage member 40 is provided above the refrigerating room damper 37 installation portion on the back surface of the heat insulating sheet 38 that covers the passage portion 21. Therefore, the dew condensation water dripping down is received by the drainage member 40, and in the present embodiment, a part other than the part where the cold room damper 37 is installed, in this embodiment, the cold room return duct 58 provided adjacent to the cold room duct 28. Drained toward (see FIG. 4).
従って、断熱シート38の背面を垂れ落ちてくる結露水が冷蔵室ダンパ37部分に侵入することを防止でき、ダンパ動作に支障を来たすことを未然に防止することができる。また、結露水は、冷蔵室戻りダクト58に向けて排水されるので、冷蔵室戻りダクト58から冷却室23に戻され、除霜運転等によって支障なく排水処理される。
Therefore, it is possible to prevent the dew condensation water that hangs down on the back surface of the heat insulating sheet 38 from entering the refrigerator compartment damper 37 and prevent the damper operation from being hindered. Further, the dew condensation water is drained toward the refrigerating room return duct 58, so that it is returned from the refrigerating room return duct 58 to the cooling chamber 23 and is drained without any trouble by a defrosting operation or the like.
特に、断熱シート38は、ダンパカバー28cの上部まで覆うようにダクト部材28aに貼り付けられている。このような構成により、ダンパカバー28c上端部とダクト部材28aとの接合部分から冷蔵室ダンパ37設置部分への結露水侵入を確実に防止できる。
In particular, the heat insulating sheet 38 is attached to the duct member 28a so as to cover the upper part of the damper cover 28c. With such a configuration, it is possible to reliably prevent the intrusion of condensed water from the joint portion between the upper end portion of the damper cover 28c and the duct member 28a into the refrigeration chamber damper 37 installation portion.
更に、本実施の形態の冷蔵庫500では、排水用部材40が、断熱シート38とダンパカバー28cとに跨って貼り付けられている。このような構成により、断熱シート38が剥がれることを防止でき、ダンパカバー28c上部の接合部からの結露水侵入をより確実に防止できる。
Furthermore, in the refrigerator 500 of the present embodiment, the drainage member 40 is pasted across the heat insulating sheet 38 and the damper cover 28c. With such a configuration, it is possible to prevent the heat insulating sheet 38 from being peeled off, and it is possible to more reliably prevent the intrusion of condensed water from the joint portion on the upper portion of the damper cover 28c.
加えて、排水用部材40が、断熱シート38とダンパカバー28cとに跨って貼り付けられているため、ダンパカバー28cを強力に固定することができる。したがって、ダンパカバー28cをダクト部材28a下部の通路部21に嵌め込むだけの構成としても、ダンパカバー28cをダクト部材28aに確実に装着固定することができる。よって、ダンパカバー固定部材を別途必要とせず、構成の合理化と簡素化とを図ることができる。
In addition, since the drainage member 40 is affixed across the heat insulating sheet 38 and the damper cover 28c, the damper cover 28c can be firmly fixed. Therefore, even when the damper cover 28c is simply fitted into the passage portion 21 below the duct member 28a, the damper cover 28c can be securely attached and fixed to the duct member 28a. Therefore, the damper cover fixing member is not required separately, and the configuration can be rationalized and simplified.
また、ダクト部材28aの通路部21を覆う断熱シート38は、断熱性を有するため、その断熱作用が働いて、結露発生の可能性を低減でき、結露水によるダンパ障害を、より効果的に防止することができる。
Moreover, since the heat insulation sheet 38 which covers the channel | path part 21 of the duct member 28a has heat insulation, the heat insulation effect | action works and it can reduce the possibility of dew condensation generation | occurrence | production and prevents the damper failure by dew condensation water more effectively. can do.
また、冷蔵室ダクト28の冷蔵室ダンパ37設置部分の冷蔵室14の内部側、すなわち冷蔵室ダクト28の前面側は、冷却室23から供給されてきた低温冷気が最初に触れ、強く冷却されて結露が生じやすい。しかし、本実施の形態の冷蔵庫500の冷蔵室ダクト28は、ダクト設置部分の壁厚がそれ以外の部分の壁厚よりも厚くなるよう構成されている。このような構成により、極端に温度が低くなることを防止できる。したがって、冷蔵室14内に多く外気が入り込むような使われ方、例えば扉7が比較的長く扉が開かれたままで使用されるようなことが多い場合であっても、冷蔵室ダクト28の冷蔵室ダンパ37設置部分前面での結露を抑制することができる。また、本実施の形態の冷蔵庫500の冷蔵室ダクト28は、冷蔵室ダンパ37設置部分以外の部分の壁厚が薄くなるよう構成されている。このような構成により、壁厚が薄くなる分だけ冷蔵室14の容積を大きくすることができる。
In addition, the inside of the refrigerator compartment 14 where the refrigerator compartment damper 37 of the refrigerator compartment duct 28 is installed, that is, the front side of the refrigerator compartment duct 28 is first cooled by the low-temperature cold air supplied from the cooling compartment 23 and strongly cooled. Condensation is likely to occur. However, the refrigerator compartment duct 28 of the refrigerator 500 of the present embodiment is configured such that the wall thickness of the duct installation portion is thicker than the wall thickness of the other portions. Such a configuration can prevent the temperature from becoming extremely low. Therefore, even when the outdoor room is used in such a way that a large amount of outside air enters into the refrigerator compartment 14, for example, when the door 7 is used with the door 7 being opened for a relatively long time, the refrigerator compartment 28 is refrigerated. Condensation on the front surface of the chamber damper 37 installation portion can be suppressed. Moreover, the refrigerator compartment duct 28 of the refrigerator 500 of this Embodiment is comprised so that wall thickness of parts other than the refrigerator compartment damper 37 installation part may become thin. With such a configuration, the volume of the refrigerator compartment 14 can be increased by the amount that the wall thickness is reduced.
以上述べたように、本実施の形態によれば、冷蔵室14内での結露による障害を排除でき、信頼性の高い冷蔵庫を得ることができる。
As described above, according to the present embodiment, it is possible to eliminate a failure caused by condensation in the refrigerator compartment 14, and to obtain a highly reliable refrigerator.
次に、第二冷凍室15の冷却について説明する。
Next, cooling of the second freezer compartment 15 will be described.
第二冷凍室15は、冷却ファン25の下流側からの冷気が、冷凍室カバー32に設けられた冷気吹出し口43aから供給されることにより冷却される(図16および図17参照)。第二冷凍室15を冷却した冷気は、第一冷凍室18の下部に設けられた冷凍冷気戻り口64から冷却室23へと戻る。
The second freezer compartment 15 is cooled by supplying cold air from the downstream side of the cooling fan 25 through a cold air outlet 43a provided in the freezer compartment cover 32 (see FIGS. 16 and 17). The cold air that has cooled the second freezing chamber 15 returns to the cooling chamber 23 from the freezing cold air return port 64 provided at the lower portion of the first freezing chamber 18.
ここで、冷気吹出し口43aが、図16に示すように、冷凍室カバー32から前方に向けて突出された冷気ガイド部44の前面、および、製氷室16側とは反対側の側面部に形成されている。このような構成により、第二冷凍室15には、冷却ファン25からの冷気が、冷気ガイド部44の前面に開口する冷気吹出し口43aから吹き出される冷気だけでなく、冷気ガイド部44の製氷室16側とは反対側に開口する冷気吹出し口43aから吹き出される冷気も、供給される。
Here, as shown in FIG. 16, the cold air outlet 43a is formed on the front surface of the cold air guide portion 44 protruding forward from the freezer compartment cover 32 and on the side surface portion opposite to the ice making chamber 16 side. Has been. With such a configuration, in the second freezer compartment 15, the cold air from the cooling fan 25 is not only the cold air blown from the cold air outlet 43 a that opens to the front surface of the cold air guide portion 44, but also the ice making of the cold air guide portion 44. Cold air blown out from the cold air outlet 43a that opens to the side opposite to the chamber 16 side is also supplied.
したがって、冷却ファン25が第二冷凍室15のセンターから製氷室16側に偏って位置していても、冷却ファン25からの冷気は、第二冷凍室15内の受け皿45の、製氷室16側とは反対側にも、十分供給される。よって、このような構成により、第二冷凍室15内の受け皿45内に均等に冷気が行き渡るようになり、第二冷凍室15の冷却ムラを解消することができる。
Therefore, even if the cooling fan 25 is biased to the ice making chamber 16 side from the center of the second freezing chamber 15, the cold air from the cooling fan 25 remains on the ice making chamber 16 side of the tray 45 in the second freezing chamber 15. The other side is also fully supplied. Therefore, with such a configuration, cold air can be evenly distributed in the tray 45 in the second freezer compartment 15, and uneven cooling of the second freezer compartment 15 can be eliminated.
特に、本実施の形態の冷蔵庫500では、冷気吹出し口43aは、細分化されて複数設けられている。このような構成により、冷気を分散させて第二冷凍室15に供給することができ、より一層確実に第二冷凍室15の冷却ムラを解消することができる。
Particularly, in the refrigerator 500 of the present embodiment, the cold air outlet 43a is divided into a plurality of pieces. With such a configuration, the cold air can be dispersed and supplied to the second freezer compartment 15, and the cooling unevenness of the second freezer compartment 15 can be more reliably eliminated.
更に、冷気ガイド部44には、前面、および、製氷室16側とは反対側の側面部とともに、下面にも冷気吹出し口43aaが設けられている。このような構成により、第二冷凍室15の背面壁部近傍にも冷気を供給することができる。したがって、第二冷凍室15の背面壁部に生じがちな結露を防止することができる。
Further, the cold air guide portion 44 is provided with a cold air outlet 43aa on the lower surface as well as the front surface and the side surface opposite to the ice making chamber 16 side. With such a configuration, it is possible to supply cold air also to the vicinity of the back wall portion of the second freezer compartment 15. Therefore, dew condensation that tends to occur on the back wall of the second freezer compartment 15 can be prevented.
また、第二冷凍室15に設けられた受け皿45は、図18に示すように、底面に複数のリブ45aが設けられている。このような構成により、冷気吹出し口43aからの冷気は、リブ45aに案内されて受け皿45内に効率よく分散される。また、リブ45aに載置された冷却プレート47は、熱伝導性の良い材料で形成されている。このような構成により、冷却プレート47上に載置された食品を効率よくムラなく冷却することができる。
Further, as shown in FIG. 18, the tray 45 provided in the second freezer compartment 15 is provided with a plurality of ribs 45a on the bottom surface. With such a configuration, the cold air from the cold air outlet 43a is guided by the rib 45a and efficiently dispersed in the tray 45. The cooling plate 47 placed on the rib 45a is formed of a material having good thermal conductivity. With such a configuration, the food placed on the cooling plate 47 can be efficiently and uniformly cooled.
特に、リブ45aは、受け皿45の前後方向に向けて設けられているとともに、冷却プレート47は、前方部分のリブ45a上に載置されている。このような構成により、第二冷凍室15に吹出された冷気は、前後方向のリブ45aによって効率よく前方まで分散供給されることができるとともに、冷却プレート47上に載置された食品は、第二冷凍室15の前方側に位置することになり、取り出しが容易になり、使い勝手を向上させることができる。
Particularly, the rib 45a is provided in the front-rear direction of the tray 45, and the cooling plate 47 is placed on the rib 45a in the front portion. With such a configuration, the cold air blown into the second freezer compartment 15 can be efficiently distributed and fed forward by the front and rear ribs 45a, and the food placed on the cooling plate 47 is It will be located in the front side of the two freezer compartments 15, it will become easy to take out, and usability can be improved.
最後に、第一冷凍室18の冷却について説明する。
Finally, cooling of the first freezer compartment 18 will be described.
第一冷凍室18は、図25に示すように、冷凍室カバー32に設けられた冷気吹出し口63から供給される冷気により冷却される。第一冷凍室18を冷却した冷気は、製氷室16および第二冷凍室15を冷却した冷気とともに、第一冷凍室18の下部に設けられた冷凍冷気戻り口64から冷却室23へと戻る。
The first freezer compartment 18 is cooled by cold air supplied from a cold air outlet 63 provided in the freezer compartment cover 32 as shown in FIG. The cold air that has cooled the first freezing chamber 18 returns to the cooling chamber 23 from the freezing cold air return port 64 provided in the lower portion of the first freezing chamber 18 together with the cold air that has cooled the ice making chamber 16 and the second freezing chamber 15.
ここで、本実施の形態の冷蔵庫500は、第一冷凍室18の冷凍冷気戻り口64に冷凍室ダンパ68が設けられている。このような構成により、第一冷凍室18へ供給される冷気の量を制御することができる。すなわち、第一冷凍室18が設定温度になっているのにもかかわらず、冷蔵室14の温度が高くて圧縮機27および冷却ファン25が駆動された場合、冷気が第一冷凍室18へ供給されて過度に冷却されることを防止することができ、良好な冷凍保存を実現することができる。
Here, in the refrigerator 500 of the present embodiment, a freezer compartment damper 68 is provided at the freezer cold air return port 64 of the first freezer compartment 18. With such a configuration, the amount of cold air supplied to the first freezer compartment 18 can be controlled. That is, when the temperature of the refrigerator compartment 14 is high and the compressor 27 and the cooling fan 25 are driven even though the first freezer compartment 18 is at the set temperature, cold air is supplied to the first freezer compartment 18. Can be prevented from being excessively cooled, and good frozen storage can be realized.
本実施の形態の冷蔵庫500では、特に、冷凍室ダンパ68は、図25に示すように、第一冷凍室18の冷気吹出し口63側ではなく、第一冷凍室18下部の冷凍冷気戻り口64側に設けられている。したがって、構成の簡素化を図りつつ、安定したダンパ動作を得ることができる。よって、第一冷凍室18の温度制御精度を向上させ、信頼性を高めることができる。
In the refrigerator 500 of the present embodiment, in particular, as shown in FIG. 25, the freezer compartment damper 68 is not the cold air outlet 63 side of the first freezer compartment 18 but the freezer cold air return port 64 at the lower part of the first freezer compartment 18. On the side. Therefore, a stable damper operation can be obtained while simplifying the configuration. Therefore, the temperature control accuracy of the first freezer compartment 18 can be improved and the reliability can be enhanced.
すなわち、第一冷凍室18は、冷却室23の前面に、冷却室23と前後方向において隣り合わせに設けられている。冷却室23の前面を覆う冷凍室カバー32に設けられた冷気吹出し口63が、冷却室23の冷却ファン25の下流側と連通している。このような構成により、冷却器24の除霜運転時、除霜した後の高湿の暖冷気が、そのドラフトにより冷却室23を上昇して冷気吹出し口63まで達する。したがって、冷気吹出し口63側に冷凍室ダンパ68が設けられていると、この高温高湿の暖冷気が冷凍室ダンパ68に触れて結露し、除霜運転終了後の冷却運転再開時に結氷して動作不良を起こす虞がある。このため、この結氷を防止するために、冷凍室ダンパ68に結氷防止専用のヒータを設けなくてはならないため、構成が複雑化する。
That is, the first freezing chamber 18 is provided on the front surface of the cooling chamber 23 next to the cooling chamber 23 in the front-rear direction. A cold air outlet 63 provided in the freezer compartment cover 32 that covers the front surface of the cooling chamber 23 communicates with the downstream side of the cooling fan 25 in the cooling chamber 23. With such a configuration, during the defrosting operation of the cooler 24, the high-humidity warm air after defrosting moves up the cooling chamber 23 by the draft and reaches the cold air outlet 63. Therefore, if the freezer compartment damper 68 is provided on the cold air outlet 63 side, the hot and cold air of high temperature and high humidity is condensed by touching the freezer compartment damper 68, and is frozen when the cooling operation is resumed after the defrosting operation is completed. There is a risk of malfunction. For this reason, in order to prevent this icing, the freezer compartment damper 68 must be provided with a heater dedicated to preventing icing, which complicates the configuration.
しかしながら、本実施の形態の冷蔵庫500のように、冷凍室ダンパ68が、冷却室23下部の冷凍冷気戻り口64に設けられていれば、除霜時に発生する高湿の暖冷気は、その大部分がドラフトにより冷凍冷気戻り口64より上方で発生することになり、そのまま上昇する。したがって、冷凍室ダンパ68に触れる暖冷気は、ごく少量かつ湿度も少なくなり、暖冷気が結露して生じる結氷も軽微になる。しかも、この結氷は、除霜のためのガラス管ヒータ26による余熱で防止することができる。したがって、冷凍室ダンパ68の動作を安定にすることができる。しかも、除霜用のガラス管ヒータ26を利用しているので、除霜専用のヒータ等を必要とせず、構成も簡素にできる。つまり、温度制御精度を向上させると同時に、信頼性を向上させることができる。
However, as in the refrigerator 500 of the present embodiment, if the freezer damper 68 is provided in the freezing cold air return port 64 at the lower part of the cooling chamber 23, the high-humidity warm air generated during defrosting is large. The portion is generated above the refrigerated cold air return port 64 by the draft, and rises as it is. Therefore, the amount of warm and cool air that touches the freezer compartment damper 68 is very small and the humidity is low, and icing caused by the condensation of warm and cool air is light. Moreover, this icing can be prevented by residual heat from the glass tube heater 26 for defrosting. Therefore, the operation of the freezer damper 68 can be stabilized. And since the glass tube heater 26 for defrosting is utilized, the heater for exclusive use of a defrost etc. is not required but a structure can also be simplified. That is, it is possible to improve the temperature control accuracy and at the same time improve the reliability.
さらに、冷凍室ダンパ68は、除霜時に生じる除霜水の一部が垂れ落ちてきて冷凍室ダンパ68を駆動する冷凍ダンパ駆動用モータ72の端子取り出し部のコネクタ端子部79に侵入することが懸念される。しかしながら、本実施の形態の冷蔵庫500では、冷凍ダンパ駆動用モータ72の端子取り出し部は、図31に示すように、二枚の電気絶縁板80で絶縁保護されたうえで、その上方から保護ボックス81で覆われている。更に、保護ボックス81の開口端側は、シール部材82で嵌み込まれており、シール部材82は、冷却室側口枠部66に設けられた支持枠片83(図30参照)により押さえつけられている。したがって、上述したように、除霜水が垂れ落ちてきても、これが充電部(コネクタ端子部79)にまで侵入することを防止することができる。したがって、冷凍室ダンパ68が冷凍冷気戻り口64に設けられていても、何ら問題なく安心して使用でき、信頼性の高い冷気制御構成が得られる。
Furthermore, the freezer compartment damper 68 may intrude into the connector terminal portion 79 of the terminal takeout portion of the freezer damper driving motor 72 that drives the freezer compartment damper 68 due to a part of the defrosted water generated during the defrosting dripping down. Concerned. However, in the refrigerator 500 according to the present embodiment, the terminal extraction portion of the refrigeration damper driving motor 72 is insulated and protected by two electrical insulating plates 80 as shown in FIG. 81. Furthermore, the opening end side of the protective box 81 is fitted with a seal member 82, and the seal member 82 is pressed down by a support frame piece 83 (see FIG. 30) provided in the cooling chamber side frame portion 66. ing. Therefore, as described above, even if the defrost water falls down, it can be prevented that it enters the charging part (connector terminal part 79). Therefore, even if the freezer compartment damper 68 is provided in the freezing cold air return port 64, it can be used safely without any problem, and a highly reliable cold air control configuration can be obtained.
しかも、冷凍室ダンパ68は、冷却室23と第一冷凍室18との間を区画する冷却室カバー31と、冷凍室カバー32とで挟持されて固定されている。このような構成により、冷凍室ダンパ68の冷凍ダンパ駆動用モータ72に設けられたシール部材82は、冷却室カバー31および冷凍室カバー32を利用して固定されることができ、構成の簡素化を図ることができる。
Moreover, the freezer compartment damper 68 is sandwiched and fixed between the cooling compartment cover 31 that partitions the cooling compartment 23 and the first freezing compartment 18 and the freezer compartment cover 32. With such a configuration, the seal member 82 provided on the freezing damper driving motor 72 of the freezing chamber damper 68 can be fixed using the cooling chamber cover 31 and the freezing chamber cover 32, and the configuration is simplified. Can be achieved.
加えて、冷凍室ダンパ68の充電部(コネクタ端子79)をシールするシール部材82は、冷凍室カバー32によって固定されているから、シール部材82の固定構成も簡素化でき、更に構成の簡素化を図ることができる。
In addition, since the seal member 82 that seals the charging portion (connector terminal 79) of the freezer compartment damper 68 is fixed by the freezer compartment cover 32, the fixing configuration of the seal member 82 can be simplified, and the configuration is further simplified. Can be achieved.
また、冷凍室ダンパ68は、複数のフラップ71の組み合わせで構成されている。このような構成により、複数のフラップ71それぞれが開いたときの前後幅寸法は、ダンパが一枚フラップで構成された場合に比べ、大幅に小さくすることができる。したがって、冷凍室ダンパ68自体をコンパクト化できると同時に、冷凍室ダンパ68を設けるスペースも大幅に縮小することができ、その分、第一冷凍室18内の容積を増加させることができる。
Moreover, the freezer damper 68 is configured by a combination of a plurality of flaps 71. With such a configuration, the front-rear width dimension when each of the plurality of flaps 71 is opened can be significantly reduced as compared with the case where the damper is configured with a single flap. Therefore, the freezer compartment damper 68 itself can be made compact, and at the same time, the space for installing the freezer compartment damper 68 can be greatly reduced, and the volume in the first freezer compartment 18 can be increased accordingly.
加えて、冷凍室ダンパ68の複数のフラップ71それぞれは、冷却室23側に向かって開くように設けられている。このような構成によっても、第一冷凍室18内の容積を増加させることができる。すなわち、複数のフラップ71それぞれが第一冷凍室18側に向かって開くように設けられていると、複数のフラップ71それぞれが第一冷凍室18側に突出する状態となり、その分、冷凍室容器62を前方に位置させなければならなくなる。したがって、冷凍室容器62の容積、つまり第一冷凍室18の容積を少なくせざるを得なくなる。しかし、本実施の形態の冷蔵庫500のような構成にすることにより、このような問題は解消でき、第一冷凍室18の容積を増加させることができる。
In addition, each of the plurality of flaps 71 of the freezer damper 68 is provided so as to open toward the cooling chamber 23 side. Also with such a configuration, the volume in the first freezer compartment 18 can be increased. That is, when each of the plurality of flaps 71 is provided so as to open toward the first freezer compartment 18 side, each of the plurality of flaps 71 protrudes toward the first freezer compartment 18 side, and accordingly, the freezer compartment container. 62 will have to be positioned forward. Therefore, the volume of the freezer compartment 62, that is, the volume of the first freezer compartment 18 must be reduced. However, such a problem can be solved by adopting a configuration like the refrigerator 500 of the present embodiment, and the volume of the first freezer compartment 18 can be increased.
また、図28に示すように、冷凍室ダンパ68が装着された冷凍冷気戻り口64の冷却室側口枠部66を、垂線に対し、上部側ほど後方に位置するように、すなわち、冷却室23側に位置するように、傾斜させている。また、冷却室側口枠部66に装着された冷凍室ダンパ68の冷却室23側を、冷凍室ダンパ68の第一冷凍室18側に対し、下方に位置するように傾斜させている。このような構成により、冷却器24の除霜運転時に冷却室23内に生じた暖冷気が、冷却室側口枠部66に触れてこれが結露するようなことがあっても、この結露水は、冷却室23側に流下し、排水口36より外部へ排水される。したがって、結露水が第一冷凍室18側に流下し、第一冷凍室18内で氷結し氷塊となって障害を引き起こすようなことを防止できる。
Further, as shown in FIG. 28, the cooling chamber side opening frame portion 66 of the refrigeration cold air return port 64 to which the freezing chamber damper 68 is mounted is positioned so as to be located rearward from the vertical line, that is, the cooling chamber. It is inclined so as to be located on the 23 side. In addition, the cooling chamber 23 side of the freezing chamber damper 68 attached to the cooling chamber side opening frame portion 66 is inclined with respect to the first freezing chamber 18 side of the freezing chamber damper 68 so as to be positioned below. With such a configuration, even if the warm air generated in the cooling chamber 23 during the defrosting operation of the cooler 24 may come into contact with the cooling chamber side opening 66 and the condensed water, Then, it flows down to the cooling chamber 23 side and is drained from the drain port 36 to the outside. Therefore, it is possible to prevent the dew condensation water from flowing down to the first freezer compartment 18 side and icing in the first freezer compartment 18 to form an ice block and causing a failure.
なお、通常、除霜運転時には、冷凍室ダンパ68は閉じられており、冷却室23内の暖冷気が、第一冷凍室18内に入り込まないように構成されている。
In addition, normally, at the time of a defrost operation, the freezer compartment damper 68 is closed, and it is comprised so that the warm air in the cooling chamber 23 may not enter into the 1st freezer compartment 18.
また、冷凍室ダンパ68は、冷却室23下部のガラス管ヒータ26と近接しているため、除霜運転時に冷凍室ダンパ68の温度が上昇する。しかし、本実施の形態の冷蔵庫500の冷凍室ダンパ68を構成するダンパ枠体70ならびに複数のフラップ71等は、耐熱性の材料で形成されている。このような構成により、熱変形等を防止でき、長期間に亘って良好なダンパ作用を確保することができる。
Moreover, since the freezer compartment damper 68 is close to the glass tube heater 26 below the cooling chamber 23, the temperature of the freezer compartment damper 68 increases during the defrosting operation. However, the damper frame 70 and the plurality of flaps 71 constituting the freezer damper 68 of the refrigerator 500 of the present embodiment are formed of a heat resistant material. With such a configuration, thermal deformation and the like can be prevented, and a good damper action can be secured over a long period of time.
特に、本実施の形態の冷蔵庫500では、冷凍室ダンパ68は、その下部(ダンパ枠体70の下辺部分)が、ガラス管ヒータ26の真横ではなく、それよりも上方に位置するように設けられている。このような構成により、冷凍室ダンパ68は、ガラス管ヒータ26から上方に離れる位置に配置されるため、輻射熱線による直接的な熱影響を低減することができ、温度上昇を抑制することができる。その一方で、ガラス管ヒータ26により熱せられた湿気の少ない暖冷気は、確実に冷凍室ダンパ68に触れ、冷凍室ダンパ68に着霜があったとしても、霜は確実に除霜される。よって、このような構成により、ダンパ動作を良好なものとすることができる。
In particular, in the refrigerator 500 of the present embodiment, the freezer compartment damper 68 is provided such that its lower portion (the lower side portion of the damper frame 70) is located not above the glass tube heater 26 but above it. ing. With such a configuration, the freezer damper 68 is disposed at a position away from the glass tube heater 26, so that a direct thermal effect due to radiant heat rays can be reduced, and an increase in temperature can be suppressed. . On the other hand, the warm and cool air heated by the glass tube heater 26 is surely touching the freezer compartment damper 68, and even if the freezer compartment damper 68 is frosted, the frost is reliably defrosted. Therefore, with such a configuration, the damper operation can be improved.
更に、ガラス管ヒータ26との距離が短い、冷凍室ダンパ68の下部を支持する冷却室側口枠部66の下辺66aは、冷却室23に突き出す(冷却室23の底面23aよりガラス管ヒータ26側に突き出す)ように構成されている。このような構成により、ガラス管ヒータ26からの輻射熱線が、直接、冷凍室ダンパ68のダンパ枠体70の下辺部分に照射することを防止でき、極端な温度上昇を防止することができる。しかも、冷却室側口枠部66の下辺66aは、二重壁として形成され、間隙部分66bは、第一冷凍室18に面して開放するように構成されている。このような構成により、第一冷凍室18内の冷気による冷却作用が加わって、冷凍室ダンパ68の極端な昇温を防止でき、良好な動作を保証することができる。
Further, the lower side 66a of the cooling chamber side frame 66 that supports the lower portion of the freezer damper 68, which is short from the glass tube heater 26, protrudes into the cooling chamber 23 (the glass tube heater 26 from the bottom surface 23a of the cooling chamber 23). Projecting to the side). With such a configuration, it is possible to prevent the radiant heat rays from the glass tube heater 26 from directly irradiating the lower side portion of the damper frame 70 of the freezer compartment damper 68, thereby preventing an extreme temperature rise. Moreover, the lower side 66a of the cooling chamber side frame portion 66 is formed as a double wall, and the gap portion 66b is configured to open facing the first freezer compartment 18. With such a configuration, a cooling action by the cold air in the first freezer compartment 18 is added, an extreme temperature rise of the freezer compartment damper 68 can be prevented, and good operation can be guaranteed.
また冷凍室ダンパ68は、図26に示すように、冷凍ダンパ駆動用モータ72が、ガラス管ヒータ26のヒータ部26aと対向しない位置、本実施の形態では、冷却室23横の冷蔵室戻りダクト58および野菜室ダクト30が配置されている側に設けられている。このような構成により、冷凍ダンパ駆動用モータ72に対するガラス管ヒータ26からの輻射熱線の照射による直接的な熱影響を和らげることができる。これにより、複数の歯車等を内蔵していて精密部品となっている冷凍ダンパ駆動用モータ72の、極端な温度上昇を防止でき、冷凍ダンパ駆動用モータ72の安定した動作を保証することができる。
In addition, as shown in FIG. 26, the freezer damper 68 has a freezer damper drive motor 72 at a position where it does not face the heater portion 26a of the glass tube heater 26, in this embodiment, a refrigerator return duct next to the cooler 23. 58 and the vegetable compartment duct 30 are provided on the side where they are arranged. With such a configuration, it is possible to relieve the direct thermal effect of the radiant heat rays from the glass tube heater 26 on the refrigeration damper driving motor 72. As a result, an extreme temperature rise of the refrigeration damper driving motor 72, which is a precision part and includes a plurality of gears, can be prevented, and a stable operation of the refrigeration damper driving motor 72 can be ensured. .
このように、冷凍ダンパ駆動用モータ72が、ヒータ部26aの外方に位置する状態を維持しつつ、冷凍室ダンパ68は、冷凍ダンパ駆動用モータ72が冷却室23横に位置する冷蔵室戻りダクト58側に位置するようにして設けられている。このような構成により、複数のフラップ71部分が、冷却器24の中心線寄り部分に位置するようになり、冷却室23へ戻る冷気を効率よく冷却器24に触れさせることができる。これにより、冷却器24は、冷却器24自体が持つ本来の冷却性能を十二分に発揮可能となり、冷却性能を大きく向上させることができる。
In this way, while the refrigeration damper driving motor 72 is maintained outside the heater portion 26a, the freezing compartment damper 68 is returned to the refrigeration compartment where the refrigeration damper driving motor 72 is located beside the cooling chamber 23. It is provided so as to be located on the duct 58 side. With such a configuration, the plurality of flaps 71 are positioned closer to the center line of the cooler 24, and the cool air returning to the cooling chamber 23 can be efficiently contacted with the cooler 24. Thereby, the cooler 24 can fully exhibit the original cooling performance of the cooler 24 itself, and can greatly improve the cooling performance.
しかも、冷凍室ダンパ68は、その上部(ダンパ枠体70の上片部分)が冷却器24の下端縁より上方に位置し、かつ、その下部(ダンパ枠体70の下辺66a部分)が冷却器24の下端より下方に位置するように設けられている。このような構成により、冷却室23へと戻る冷気を、確実に冷却器24の下端面より下方部分に流れるようにすることができる。したがって、冷気は、その大部分が冷却器24の下端面から上方へと流れるようになり、冷却器24全体を有効に活用した冷却が可能となって、更にその冷却性能を向上させることができる。
Moreover, the freezer damper 68 has an upper portion (an upper piece portion of the damper frame 70) located above the lower end edge of the cooler 24, and a lower portion (a lower side 66a portion of the damper frame 70) that is a cooler. It is provided so as to be located below the lower end of 24. With such a configuration, the cool air returning to the cooling chamber 23 can surely flow from the lower end surface of the cooler 24 to the lower part. Therefore, most of the cold air flows upward from the lower end surface of the cooler 24, enabling cooling utilizing the entire cooler 24 effectively, and further improving the cooling performance. .
一方、冷凍冷気戻り口64には、冷凍室ダンパ68の第一冷凍室18側に、グリル67が装着されている。グリル67の複数のグリル片69それぞれは、冷却室23側の端部が第一冷凍室18側の端部より上方に位置するように傾斜させて設けられている。このような構成により、冷凍室容器62が引き出された時、各グリル片69の間からその奥に位置するガラス管ヒータ26等が見えることを防止でき、意匠性を向上させることができるとともに、使用者に違和感等を与えることをなくすことができる。
On the other hand, a grill 67 is attached to the freezing cold air return port 64 on the first freezing chamber 18 side of the freezing chamber damper 68. Each of the plurality of grill pieces 69 of the grill 67 is provided so as to be inclined so that the end portion on the cooling chamber 23 side is positioned above the end portion on the first freezing chamber 18 side. With such a configuration, when the freezer compartment 62 is pulled out, it is possible to prevent the glass tube heaters 26 and the like located behind the grill pieces 69 from being seen, and the design can be improved. The user can be prevented from feeling uncomfortable.
また、グリル67の複数のグリル片69は、下方に位置するグリル片69ほど前後長が長くなるように形成されている。すなわち、複数のグリル片69は、第一冷凍室18内の冷凍室容器62後面の形状に沿うように各グリル片69の前後長が調整されて、構成されている。このような構成により、第一冷凍室18内での冷気の流れをスムーズにでき、冷却性能を向上させることができる。
Further, the plurality of grill pieces 69 of the grill 67 are formed such that the front and rear lengths of the grill pieces 69 positioned lower are longer. That is, the plurality of grill pieces 69 are configured such that the front and rear lengths of the grill pieces 69 are adjusted so as to follow the shape of the rear surface of the freezer compartment 62 in the first freezer compartment 18. With such a configuration, the flow of cool air in the first freezer compartment 18 can be made smooth, and the cooling performance can be improved.
本開示は、野菜室ダクトの全長を短くして冷気循環量の低下を抑制すると同時に、野菜室ダクトの全長を短くしたことによって生じる冷凍室容積の減少も最小限に抑制して冷凍室容積を確保できる冷蔵庫を提供する。よって、家庭用および業務用など様々な種類および大きさの冷蔵庫並びに冷却装置等に適用できる。
