Description

本発明は、貯蔵室内に食品等を冷却保存する冷蔵庫に関し、特に、冷気が流れる供給風路を必要に応じて塞ぐ遮蔽装置を備えた冷蔵庫に関する。 The present invention relates to a refrigerator that cools and stores foods and the like in a storage chamber, and particularly relates to a refrigerator that includes a shielding device that blocks a supply air passage through which cold air flows as necessary.

従来、冷却室内の冷却器で冷却された空気を、供給風路を経由して貯蔵室に供給する構成の冷蔵庫において、除霜運転中の暖気が貯蔵室に流入することを防止するため、冷却室の送風口に該送風口を塞ぐ遮蔽装置を設けることが知られている(例えば、特許文献1、特許文献2)。 Conventionally, in a refrigerator configured to supply air cooled by a cooler in a cooling chamber to a storage chamber via a supply air passage, in order to prevent warm air during defrosting operation from flowing into the storage chamber, cooling is performed. It is known to provide a shielding device that closes the air outlet of the chamber (for example, Patent Document 1 and Patent Document 2).

図13(A)及び(B)は、特許文献1に開示された遮蔽装置150を示す斜視図であり、図13(A)は、送風機カバー160を閉じた状態、図13(B)は、送風機カバー160を開いた状態を示している。図13(A)及び(B)に示すように、遮蔽装置150は、冷却室の送風口に取り付けられた送風機140の吐出側に設けられ、ファン142の回転軸方向に往復動自在な送風機カバー160を有する。 13A and 13B are perspective views showing the shielding device 150 disclosed in Patent Document 1, FIG. 13A is a state in which the blower cover 160 is closed, and FIG. It shows a state in which the blower cover 160 is opened. As shown in FIGS. 13A and 13B, the shielding device 150 is provided on the discharge side of the blower 140 attached to the blower port of the cooling chamber, and is a blower cover that can reciprocate in the rotation axis direction of the fan 142. Having 160.

図13(A)の如く、送風機カバー160が送風機140に接近すると、送風機カバー160の周縁部が送風機140のケーシング141に嵌合し、送風機140の空気流路が塞がれる。他方、図13(B)の如く、送風機カバー160が送風機140から離隔する方向に移動すると、送風機カバー160とケーシング141との間に空気が流れるための流路が形成される。そして、矢印Vで模式的に示すように、送風機140によって吐出された空気が流れ出す。 As shown in FIG. 13A, when the blower cover 160 approaches the blower 140, the peripheral edge of the blower cover 160 fits into the casing 141 of the blower 140, and the air flow path of the blower 140 is closed. On the other hand, as shown in FIG. 13B, when the blower cover 160 moves in a direction away from the blower 140, a flow path for air to flow is formed between the blower cover 160 and the casing 141. Then, as schematically shown by the arrow V, the air discharged by the blower 140 flows out.

なお、送風機140は、軸流送風機であり、送風機140のファンモータ143は、支持フレーム148によってケーシング141に固定されている。また、送風機カバー160は、送風機140のケーシング141に設けられたガイドピン152によって支持されている。 The blower 140 is an axial blower, and the fan motor 143 of the blower 140 is fixed to the casing 141 by the support frame 148. Further, the blower cover 160 is supported by guide pins 152 provided on the casing 141 of the blower 140.

図14は、特許文献2に開示された遮蔽装置250を示す分解斜視図である。図14に示すように、同文献に開示された遮蔽装置250は、支持基体251に立設されたガイドピン252によって摺動可能に支持された送風機カバー260を有する。送風機カバー260は、送風機カバー260を貫通して配置されて送風機カバー260のねじ孔263に螺合する駆動軸267によって開閉される。 FIG. 14 is an exploded perspective view showing the shielding device 250 disclosed in Patent Document 2. As shown in FIG. 14, the shielding device 250 disclosed in the document has a blower cover 260 slidably supported by guide pins 252 provided upright on a support base 251. The blower cover 260 is opened and closed by a drive shaft 267 which is disposed so as to penetrate the blower cover 260 and is screwed into the screw hole 263 of the blower cover 260.

駆動軸267を駆動するモータは軸支持部255に内蔵されており、軸支持部255は、支持フレーム258によって支持基体251の枠部253に連結されている。そして、支持基体251は、冷却室の送風口に取り付けられた図示しない送風機のケーシングに取り付けられている。 A motor that drives the drive shaft 267 is built in the shaft support portion 255, and the shaft support portion 255 is connected to the frame portion 253 of the support base 251 by the support frame 258. The support base 251 is attached to the casing of a blower (not shown) attached to the blower opening of the cooling chamber.

しかしながら、上記した従来技術の冷蔵庫では、冷蔵庫の冷却性能を向上させるために、遮蔽装置及び送風機に関し、改善すべき点があった。 However, in the above-described refrigerator of the related art, there is a point to be improved regarding the shielding device and the blower in order to improve the cooling performance of the refrigerator.

具体的には、冷蔵庫の冷却性能を向上させるためには、貯蔵室に供給される空気の送風効率を高めて、空気の流量を増やすことが有効である。しかし、上記した特許文献1及び特許文献2に開示された送風機の構成では、図13に示すように、空気の流路にファンモータ143を支持するための支持フレーム148が存在するため、支持フレーム148によって空気の流れが阻害される恐れがあった。 Specifically, in order to improve the cooling performance of the refrigerator, it is effective to increase the blowing efficiency of the air supplied to the storage room and increase the flow rate of the air. However, in the configuration of the blower disclosed in Patent Document 1 and Patent Document 2 described above, as shown in FIG. 13, since the support frame 148 for supporting the fan motor 143 exists in the air flow path, the support frame The air flow could be obstructed by 148.

また、図14に示す特許文献2に開示された遮蔽装置250のように、送風機のケーシングに取り付けられる支持基体251によって支持された駆動軸267によって送風機カバー260を開閉する構成では、駆動軸267を支える支持フレーム258が空気の流路に跨って配置されることになる。そのため、空気の流路に配置される支持フレーム258によって、空気の流動損失が生ずる。 Further, like the shielding device 250 disclosed in Patent Document 2 shown in FIG. 14, in the configuration in which the blower cover 260 is opened and closed by the drive shaft 267 supported by the support base 251 attached to the casing of the blower, the drive shaft 267 is The supporting frame 258 for supporting is arranged so as to straddle the flow path of air. Therefore, the support frame 258 arranged in the air flow path causes a flow loss of air.

また、特許文献2に開示された従来技術の冷蔵庫では、送風機カバー260を開閉する際の振動が仕切部材等に伝播し易く、それによって騒音が発生する恐れがある。特に、冷蔵庫の冷却性能を向上させるべく、送風機カバー260を閉じた際の密封シール性を高めて暖気の漏れを抑制するよう、送風機カバー260を支持基体251に押し当てるように駆動軸267を駆動すると、比較的大きな振動や騒音が発生し易い。 Further, in the conventional refrigerator disclosed in Patent Document 2, vibration when opening and closing the blower cover 260 easily propagates to the partition member and the like, which may cause noise. In particular, in order to improve the cooling performance of the refrigerator, the drive shaft 267 is driven so as to press the blower cover 260 against the support base 251 so as to improve the hermetic sealing property when the blower cover 260 is closed and suppress the leakage of warm air. Then, relatively large vibration and noise are likely to occur.

It is composed of an inner box 2b made of synthetic resin and a heat insulating material 2c made of foamed polyurethane that is filled and foamed in the gap between the outer box 2a and the inner box 2b. The heat insulating doors 8 to 12 also have the same heat insulating structure as the heat insulating box 2.

冷蔵室3と、その下段に位置する冷凍室4Aは、断熱仕切壁28によって区画されている。冷凍室4Aの内部の製氷室4と上段冷凍室5との間は、仕切壁(図面に表れない)によって仕切られている。また、製氷室4及び上段冷凍室5と、その下段に設けられた下段冷凍室6との間は、冷気が流通自在に連通している。そして、冷凍室4Aと野菜室7は、断熱仕切壁29によって区画されている。 The refrigerating compartment 3 and the freezing compartment 4A located below it are partitioned by a heat insulating partition wall 28. A partition wall (not shown in the drawing) separates the interior of the freezer compartment 4A from the ice compartment 4 and the upper stage freezer compartment 5. In addition, cold air is communicatably communicated between the ice making chamber 4 and the upper freezing chamber 5 and the lower freezing chamber 6 provided at the lower stage thereof. The freezer compartment 4A and the vegetable compartment 7 are partitioned by a heat insulating partition wall 29.

冷蔵室3の背面には、合成樹脂製の仕切部材27で区画され、冷蔵室3に冷気を供給する供給風路としての冷蔵室供給風路14が形成されている。冷蔵室供給風路14には、冷蔵室3に冷気を吹き出す吹出口17が形成されている。また、冷蔵室供給風路14には、冷蔵室ダンパ34が設けられている。冷蔵室ダンパ34は、モータ等によって駆動される開閉自在なダンパであり、冷蔵室3に供給する冷気の流量を制御して、冷蔵室3内部の温度を適切に維持するためのものである。 A refrigerating compartment supply air passage 14 is formed on the back surface of the refrigerating compartment 3 by a partition member 27 made of synthetic resin, and serves as a supply air passage for supplying cool air to the refrigerating compartment 3. The refrigerating compartment supply air passage 14 is formed with an outlet 17 for blowing cold air into the refrigerating compartment 3. A refrigerating compartment damper 34 is provided in the refrigerating compartment supply air passage 14. The refrigerating compartment damper 34 is a damper that is driven by a motor or the like and can be opened and closed, and controls the flow rate of the cool air supplied to the refrigerating compartment 3 to appropriately maintain the temperature inside the refrigerating compartment 3.

冷凍室4Aの後方には、冷却器32で冷却された空気を冷凍室4Aに流す供給風路である冷凍室供給風路15が形成されている。冷凍室供給風路15の更に後方には、冷却室13が形成されており、その内部には、庫内を循環する空気を冷却するための蒸発器である冷却器32が配置されている。 A freezer compartment supply air passage 15 that is a supply air passage through which the air cooled by the cooler 32 flows to the freezer compartment 4A is formed behind the freezer compartment 4A. A cooling chamber 13 is formed further behind the freezing chamber supply air passage 15, and a cooler 32, which is an evaporator for cooling the air circulating in the refrigerator, is arranged inside the cooling chamber 13.

冷却器32は、圧縮機31、図示しない放熱器、図示しない膨張弁若しくはキャピラリーチューブに冷媒配管を介して接続されており、蒸気圧縮式の冷凍サイクル回路を構成するものである。なお、本実施形態に係る冷蔵庫1では、前記冷凍サイクルの冷媒として、イソブタン、即ちR600aを用いている。 The cooler 32 is connected to the compressor 31, a radiator (not shown), an expansion valve or a capillary tube (not shown) via a refrigerant pipe, and constitutes a vapor compression refrigeration cycle circuit. In the refrigerator 1 according to the present embodiment, isobutane, that is, R600a is used as the refrigerant of the refrigeration cycle.

図3は、冷蔵庫1の供給風路の概略構成を示す正面図である。図3に示すように、冷蔵庫1は、冷蔵室3と野菜室7をつなぐ野菜室供給風路16を備えている。これにより、冷蔵室3に供給された冷気は、冷蔵室3の下部に形成された戻り口21から野菜室供給風路16に流入し、吹出口20から吹き出されて野菜室7に供給される。図2に示すように、野菜室7には、冷却室13の下部につながる戻り口24が形成されており、野菜室7内の空気は、戻り口24から冷却室13の下部へと流れる。 FIG. 3 is a front view showing a schematic configuration of a supply air passage of the refrigerator 1. As shown in FIG. 3, the refrigerator 1 includes a vegetable compartment supply air passage 16 that connects the refrigerating compartment 3 and the vegetable compartment 7. As a result, the cold air supplied to the refrigerating compartment 3 flows into the vegetable compartment supply air passage 16 from the return port 21 formed in the lower part of the refrigerating compartment 3, is blown out from the air outlet 20 and is supplied to the vegetable compartment 7. .. As shown in FIG. 2, the vegetable compartment 7 has a return port 24 connected to the lower portion of the cooling chamber 13, and the air in the vegetable compartment 7 flows from the return port 24 to the lower portion of the cooling chamber 13.

なお、冷蔵室3から冷却室13に空気を戻す帰還風路を設けると共に、冷却室13若しくは冷凍室供給風路15と野菜室7をつなぐ野菜室供給風路を設け、冷却室13から冷蔵室3を経由せずに野菜室7に冷気を供給する構成を採用することもできる。また、野菜室7に供給する冷気の流れを制御するために、野菜室ダンパが設けられても良い。 A return air passage for returning air from the refrigerating compartment 3 to the cooling compartment 13 is provided, and a vegetable compartment supply air passage for connecting the cooling compartment 13 or the freezing compartment supply air duct 15 and the vegetable compartment 7 is provided. It is also possible to adopt a configuration in which cold air is supplied to the vegetable compartment 7 without going through 3. Further, a vegetable compartment damper may be provided to control the flow of cold air supplied to the vegetable compartment 7.

図4及び図5は、冷蔵庫1の冷却室13付近の構造を示す側面断面図であり、図4は、送風機カバー60が開いている状態を示し、図5は、送風機カバー60が閉じている状態を示している。 4 and 5 are side cross-sectional views showing the structure near the cooling chamber 13 of the refrigerator 1, FIG. 4 shows a state in which the blower cover 60 is open, and FIG. 5 shows the blower cover 60 in the closed state. It shows the state.

図4に示すように、冷却室13は、断熱箱体2の内部で、冷凍室供給風路15の奥側に設けられている。冷却室13と、冷凍室供給風路15または冷凍室4Aとの間は、合成樹脂製の仕切部材25によって仕切られている。即ち、冷却室13は、内箱2bと仕切部材25によって挟まれて形成された空間である。 As shown in FIG. 4, the cooling chamber 13 is provided inside the heat insulating box 2 on the inner side of the freezing chamber supply air passage 15. A partition member 25 made of synthetic resin partitions the cooling chamber 13 from the freezing chamber supply air passage 15 or the freezing chamber 4A. That is, the cooling chamber 13 is a space formed by being sandwiched between the inner box 2b and the partition member 25.

冷却室13の前方に形成された冷凍室供給風路15は、仕切部材25とその前方に組み付けられた仕切部材35との間に形成された空間であり、冷却器32で冷却された冷気が流れる供給風路となる。冷凍室供給風路15の上部は、冷蔵室供給風路14につながっている。 The freezer compartment supply air passage 15 formed in front of the cooling chamber 13 is a space formed between the partition member 25 and the partition member 35 assembled in front of the partition member 25, and cool air cooled by the cooler 32 It becomes a flowing supply air passage. The upper part of the freezer compartment supply air passage 15 is connected to the refrigerating compartment supply air passage 14.

仕切部材35には、冷凍室4Aに冷気を吹き出す開口である吹出口18が形成されている。下段冷凍室6の下部背面には、冷凍室4Aから冷却室13の下部に空気を戻す戻り口23が形成されている。 The partition member 35 is formed with a blowout port 18 which is an opening for blowing cold air to the freezer compartment 4A. A return port 23 for returning air from the freezing chamber 4A to the lower part of the cooling chamber 13 is formed on the lower rear surface of the lower freezing chamber 6.

また、冷却器32の下方には、冷却器32に付着した霜を融かして除去する除霜手段として、除霜ヒータ33が設けられている。除霜ヒータ33は、電気抵抗加熱式のヒータである。なお、除霜手段として、例えば、電気ヒータを利用しないオフサイクルデフロストや、ホットガスデフロスト等のその他の除霜方式を採用することも可能である。 Further, below the cooler 32, a defrost heater 33 is provided as a defrosting means for melting and removing the frost attached to the cooler 32. The defrost heater 33 is an electric resistance heating type heater. As the defrosting means, for example, off-cycle defrost that does not use an electric heater, or other defrosting method such as hot gas defrost can be adopted.

冷却室13上部の仕切部材25には、冷凍室供給風路15につながる開口である送風口26が形成されている。送風口26の前方には、冷凍室4A等に冷気を送り出す送風機40が配設されている。送風機40は、離心式のファン42を備えた離心式送風機である。 The partition member 25 above the cooling chamber 13 is formed with a blower port 26 which is an opening connected to the freezing chamber supply air passage 15. A blower 40 that blows cold air to the freezer compartment 4A and the like is disposed in front of the blower opening 26. The blower 40 is an eccentric blower including an eccentric fan 42.

送風機40の前方には、可動式の送風機カバー60を有する遮蔽装置50が設けられている。図5に示すように、送風機カバー60は、冷凍室供給風路15側から送風機40に接近して、送風機40及び送風口26を覆う。 A shielding device 50 having a movable blower cover 60 is provided in front of the blower 40. As shown in FIG. 5, the blower cover 60 approaches the blower 40 from the freezer compartment supply air passage 15 side to cover the blower 40 and the blower port 26.

送風機カバー60は、仕切部材35側に設けられる駆動軸67によって駆動されて前後方向に移動する。図4に示すように、送風機カバー60が前方に移動して送風機40から離れることにより、送風機カバー60と仕切部材25との間に空気が流通可能な流路が形成される。これにより、冷却器32で冷却された空気が送風機40で送り出されて冷蔵室3、冷凍室4A及び野菜室7に供給される。 The blower cover 60 is driven by a drive shaft 67 provided on the partition member 35 side to move in the front-rear direction. As shown in FIG. 4, the blower cover 60 moves forward and moves away from the blower 40, so that a flow passage through which air can flow is formed between the blower cover 60 and the partition member 25. As a result, the air cooled by the cooler 32 is blown out by the blower 40 and supplied to the refrigerating compartment 3, the freezing compartment 4A and the vegetable compartment 7.

他方、図5に示すように、送風機カバー60が後方に移動して送風機40に接近することにより、送風機カバー60で送風機40が覆われ、送風口26が塞がれて、冷気が流れる風路が遮蔽される。 On the other hand, as shown in FIG. 5, when the blower cover 60 moves rearward and approaches the blower 40, the blower cover 60 covers the blower 40, the blower opening 26 is closed, and the cool air flows. Is shielded.

なお、送風機カバー60は、送風機40に対向する面が略凹形状に成形されている。これにより、送風機カバー60は、送風口26の前方に配置される送風機40のファン42に接触することなく、送風機カバー60の側面部の後方端が仕切部材25の前面に当接し、送風口26を塞ぐことができる。 The surface of the blower cover 60 facing the blower 40 is formed into a substantially concave shape. As a result, the blower cover 60 does not contact the fan 42 of the blower 40 arranged in front of the blower port 26, but the rear end of the side surface portion of the blower cover 60 contacts the front surface of the partition member 25, and the blower port 26 Can be closed.

上記の遮蔽装置50の開閉動作は、図示しない制御装置によって制御され、例えば、冷却器32に付着した霜を除去する除霜運転の際に、図5に示す如く、送風機カバー60が閉じられる。 The opening/closing operation of the shielding device 50 is controlled by a control device (not shown), and for example, in the defrosting operation for removing the frost adhering to the cooler 32, the blower cover 60 is closed as shown in FIG.

詳しくは、冷却運転を継続すると、冷却器32の空気側伝熱面に霜が付着し、伝熱を妨げ、空気流路を塞ぐことになる。そこで、制御装置は、冷媒蒸発温度の低下等から着霜を判断し、或いは除霜タイマー等によって判断し、冷却器32に付着した霜を取るための除霜運転を開始する。 Specifically, when the cooling operation is continued, frost adheres to the air-side heat transfer surface of the cooler 32, hinders heat transfer, and blocks the air flow path. Therefore, the control device determines the frost formation from the decrease of the refrigerant evaporation temperature or the like, or the defrost timer or the like, and starts the defrosting operation for removing the frost adhering to the cooler 32.

除霜運転では、制御装置は、圧縮機31を停止し、除霜ヒータ33に通電する。これにより、冷却器32に付着した霜が融ける。この際、図5に示すように、送風機カバー60によって送風口26が塞がれる。これにより、除霜ヒータ33で暖められた冷却室13内の空気が冷凍室供給風路15に流れ出ることを防止できる。その結果、冷蔵庫1の冷却性能を向上させることができる。 In the defrosting operation, the control device stops the compressor 31 and energizes the defrosting heater 33. As a result, the frost attached to the cooler 32 melts. At this time, as shown in FIG. 5, the blower port 60 is closed by the blower cover 60. Thereby, the air in the cooling chamber 13 heated by the defrost heater 33 can be prevented from flowing out to the freezing chamber supply air passage 15. As a result, the cooling performance of the refrigerator 1 can be improved.

また、冷却器32の霜取りが完了すると、制御装置は、除霜ヒータ33の通電を止め、圧縮機31を起動し、冷凍回路による冷却を開始する。そして、制御装置は、冷却器32及び冷却室13が所定の温度まで冷却されたことを検出した後、或いはタイマー等で所定の時間が経過した後、図4に示すように、送風機カバー60を開き、送風機40の運転を開始する。これにより、除霜熱による影響を抑えて、冷却運転を再開することができる。 Further, when the defrosting of the cooler 32 is completed, the control device stops the energization of the defrost heater 33, activates the compressor 31, and starts cooling by the refrigeration circuit. Then, after detecting that the cooler 32 and the cooling chamber 13 have been cooled to a predetermined temperature, or after a predetermined time elapses with a timer or the like, the control device removes the blower cover 60 as shown in FIG. Open and start operation of the blower 40. Thereby, the influence of the defrosting heat can be suppressed and the cooling operation can be restarted.

次に、図6ないし図12を参照して、遮蔽装置50について詳細に説明する。図6は、遮蔽装置50の分解斜視図である。図6に示すように、遮蔽装置50は、送風機40を開閉自在に塞ぐ送風機カバー60と、送風機40を支持すると共に送風機カバー60を摺動自在に支持するベース部材51と、送風機カバー60を開閉駆動する駆動軸67と、を有する。 Next, the shielding device 50 will be described in detail with reference to FIGS. 6 to 12. FIG. 6 is an exploded perspective view of the shielding device 50. As shown in FIG. 6, the shielding device 50 includes a blower cover 60 that opens and closes the blower 40, a base member 51 that supports the blower 40 and slidably supports the blower cover 60, and opens and closes the blower cover 60. And a drive shaft 67 for driving.

遮蔽装置50は、冷凍室4Aと冷凍室供給風路15を区画する仕切部材35の冷凍室供給風路15側に取り付けられる。詳しくは、仕切部材35の後面には、略円形状で前方に向かって凹む凹部36が形成されており、遮蔽装置50は、凹部36に配設される。即ち、仕切部材35は、遮蔽装置50が配設される凹部36に相当する箇所のみが前方に突き出すことになる。このように遮蔽装置50が凹部36内に配設されることにより、仕切部材35の冷凍室4A側への突き出しを少なくして、冷凍室4Aの収納容積を広く確保することができる。 The shielding device 50 is attached to the freezer compartment supply air passage 15 side of the partition member 35 that divides the freezer compartment 4A and the freezer compartment supply air passage 15. More specifically, a substantially circular recessed portion 36 that is recessed forward is formed on the rear surface of the partition member 35, and the shielding device 50 is disposed in the recessed portion 36. That is, in the partition member 35, only a portion corresponding to the concave portion 36 in which the shielding device 50 is arranged projects forward. By disposing the shielding device 50 in the recess 36 in this way, it is possible to reduce the protrusion of the partition member 35 toward the freezing compartment 4A and ensure a large storage volume of the freezing compartment 4A.

仕切部材35の冷凍室供給風路15側を向く主面、詳しくは、凹部36内の面には、ベース部材51を固定するための支軸部37及び係止片38がそれぞれ3個ずつ後方に向かって突設されている。ベース部材51は、凹部36に形成された支軸部37及び係止片38によって仕切部材35に固定され支持される。詳細については、後述する。 Three main shafts 37 and three locking pieces 38 for fixing the base member 51 are rearward on the main surface of the partition member 35 facing the freezer compartment supply air passage 15 side, specifically, the surface inside the recess 36. Is projected toward. The base member 51 is fixed to and supported by the partition member 35 by a support shaft portion 37 and a locking piece 38 formed in the recess 36. Details will be described later.

ベース部材51には、送風機カバー60を前後方向に摺動可能に支持する略円柱状のガイドピン52が形成されている。ガイドピン52は、3本設けられ、それぞれベース部材51から後方に向かって、ファン42の回転軸に略平行に延在する。送風機カバー60には、ガイドピン52が摺動自在に嵌合するガイド孔62が形成されている。ガイド孔62にガイドピン52が挿通されて、送風機カバー60の往復動がガイドされる。 The base member 51 is provided with a substantially columnar guide pin 52 that supports the blower cover 60 slidably in the front-rear direction. Three guide pins 52 are provided, each extending rearward from the base member 51 and substantially parallel to the rotation axis of the fan 42. The blower cover 60 is formed with a guide hole 62 into which the guide pin 52 is slidably fitted. The guide pin 52 is inserted into the guide hole 62 to guide the reciprocating movement of the blower cover 60.

ベース部材51には、送風機カバー60を往復動させるための駆動軸67が取り付けられる。駆動軸67は、ベース部材51に形成された軸支持部55に嵌合し、回転自在に支持されている。 A drive shaft 67 for reciprocating the blower cover 60 is attached to the base member 51. The drive shaft 67 is fitted in a shaft support portion 55 formed on the base member 51 and is rotatably supported.

駆動軸67は、略円筒形状を呈しており、その側面の一部を螺旋状に連続して突起させた、ねじ山68が設けられている。そして、駆動軸67は、送風機カバー60に形成されたねじ孔63に螺合する。また、駆動軸67若しくは軸支持部55には図示しないモータが内蔵されており、そのモータの駆動力で駆動軸67は所定角度回転する。駆動軸67が所定の方向に回転すると、送風機カバー60が送風機40に近づき、風路が閉状態となる。他方、駆動軸67が前記所定の方向に対して逆回転に駆動されると、送風機カバー60が送風機40から離れ、風路が開状態となる。 The drive shaft 67 has a substantially cylindrical shape, and is provided with a screw thread 68 in which a part of its side surface is continuously projected in a spiral shape. Then, the drive shaft 67 is screwed into the screw hole 63 formed in the blower cover 60. A motor (not shown) is built in the drive shaft 67 or the shaft support portion 55, and the drive force of the motor causes the drive shaft 67 to rotate by a predetermined angle. When the drive shaft 67 rotates in a predetermined direction, the blower cover 60 approaches the blower 40 and the air passage is closed. On the other hand, when the drive shaft 67 is driven in the reverse rotation with respect to the predetermined direction, the blower cover 60 separates from the blower 40 and the air passage is opened.

送風機カバー60は、合成樹脂材を概略的に蓋形状に射出成形したものであり、略円形状を呈する主面部と、該主面部の周辺縁部から後方に向かって延設された側面部を有している。なお、前述のガイドピン52及びそれに嵌合するガイド孔62は、前記側面部の外側に配置される。これにより、送風機カバー60を閉じた際、ガイド孔62を通過して送風機カバー60の内側から外側に空気が漏れることがなく、送風機カバー60のシール性が高められる。 The blower cover 60 is a synthetic resin material injection-molded into a roughly lid shape, and has a substantially circular main surface portion and a side surface portion extending rearward from a peripheral edge portion of the main surface portion. Have The guide pin 52 and the guide hole 62 fitted therein are arranged outside the side surface portion. Thus, when the blower cover 60 is closed, air does not leak from the inside of the blower cover 60 to the outside when the blower cover 60 is closed, and the sealing property of the blower cover 60 is improved.

また、送風機カバー60の前記主面部の中央付近には、略円形状に貫通して内側にネジ溝が形成されたねじ孔63が形成されている。また、送風機カバー60には、仕切部材35とベース部材51を固定するためにベース部材51に形成されている支持部53が摺動自在に嵌合する貫通孔61が形成されている。 A screw hole 63 is formed in the vicinity of the center of the main surface portion of the blower cover 60, the screw hole 63 penetrating in a substantially circular shape and having a thread groove formed inside. Further, the blower cover 60 is formed with a through hole 61 into which a support portion 53 formed on the base member 51 for fixing the partition member 35 and the base member 51 is slidably fitted.

送風機40は、離心式のファン42と、ファン42を回転駆動させるファンモータ43と、ファンモータ43を支持するファンベース41と、を有する離心式送風機である。ファンベース41は、ベース部材51に取り付けられて支持される。 The blower 40 is an eccentric fan that includes an eccentric fan 42, a fan motor 43 that rotationally drives the fan 42, and a fan base 41 that supports the fan motor 43. The fan base 41 is attached to and supported by the base member 51.

なお、冷蔵庫1の生産工程においては、上記の送風機カバー60、駆動軸67及び送風機40は、予めベース部材51に組み付けられる。そして、遮蔽装置50及び送風機40が一体的に組み立てられた状態の組立品が、仕切部材35に対して組み付けられる。 In addition, in the production process of the refrigerator 1, the blower cover 60, the drive shaft 67, and the blower 40 described above are assembled to the base member 51 in advance. Then, the assembly in which the shielding device 50 and the blower 40 are integrally assembled is assembled to the partition member 35.

図7は、冷蔵庫1の遮蔽装置50付近を示す斜視断面図である。なお、図7は、送風機カバー60を開いた状態を示している。図7に示すように、冷却室13と冷凍室供給風路15をつなぐ送風口26は、略円形状の開口であり、その周囲縁部は、断面略半円状に冷却室13側に突出している。 FIG. 7 is a perspective sectional view showing the vicinity of the shielding device 50 of the refrigerator 1. Note that FIG. 7 shows a state in which the blower cover 60 is opened. As shown in FIG. 7, the blower port 26 that connects the cooling chamber 13 and the freezing chamber supply air passage 15 is a substantially circular opening, and its peripheral edge portion projects toward the cooling chamber 13 side in a substantially semicircular cross section. ing.

送風機40のファン42は、その回転軸が送風口26の中心軸と略同軸になるよう送風口26の前方に配設されている。前述のとおり、送風機40は、離心式であり、ファン42の冷却室13側の中央付近から空気を吸い込み、半径方向に効率良く空気を送り出すことができる。これにより、従来技術のように軸流送風機を採用する場合と比べ、送風効率を高め、送風量を増大させることができる。 The fan 42 of the blower 40 is arranged in front of the blower port 26 so that its rotation axis is substantially coaxial with the central axis of the blower port 26. As described above, the blower 40 is of the eccentric type, and can suck air from the vicinity of the center of the cooling chamber 13 side of the fan 42 and efficiently send the air in the radial direction. As a result, compared with the case of adopting an axial blower as in the prior art, it is possible to improve the blowing efficiency and increase the blowing amount.

図7のA部に示すように、ベース部材51は、支持部53において、仕切部材35に形成された支軸部37に支持されると共に、送風機40のファンベース41を支持している。また、図7のB部に示すように、ベース部材51は、外周部に形成された弾性部57において、仕切部材35に形成された係止片38に係合し、仕切部材35に固定されている。即ち、遮蔽装置50及び送風機40は、仕切部材35に支持されている。 As shown in part A of FIG. 7, the base member 51 is supported by the support shaft portion 37 formed on the partition member 35 in the support portion 53, and also supports the fan base 41 of the blower 40. Further, as shown in part B of FIG. 7, the base member 51 is fixed to the partition member 35 by engaging with the locking piece 38 formed on the partition member 35 in the elastic portion 57 formed on the outer peripheral portion. ing. That is, the shielding device 50 and the blower 40 are supported by the partition member 35.

このような構成により、送風機40のファンモータ43を支持するファンベース41や、送風機カバー60を駆動する駆動軸67を支持するベース部材51を、全てファン42に対して仕切部材35側に配置することが可能となる。 With such a configuration, the fan base 41 that supports the fan motor 43 of the blower 40 and the base member 51 that supports the drive shaft 67 that drives the blower cover 60 are all arranged on the partition member 35 side with respect to the fan 42. It becomes possible.

これにより、図7に示すように、送風機カバー60を開いた際に、ファンモータ43を支持する部材や、駆動軸67を支持する部材は、空気の流路に配置されず、これらの部材によって、空気の流路が妨げられることがない。よって、送風機40から送り出される空気の流動損失を低減して、冷凍室4A等の貯蔵室に供給される空気の流量を増大させて、冷蔵庫1の冷却性能を向上させることができる。 Thus, as shown in FIG. 7, when the blower cover 60 is opened, the member that supports the fan motor 43 and the member that supports the drive shaft 67 are not arranged in the air flow path, The air flow path is not obstructed. Therefore, it is possible to reduce the flow loss of the air sent from the blower 40, increase the flow rate of the air supplied to the storage room such as the freezing room 4A, and improve the cooling performance of the refrigerator 1.

図8は、図7に示すA部付近の拡大断面図であり、支持部53付近の構造を示している。図9(A)は、支持部53に設けられる緩衝部材70の縦断面図である。図9(B)は、図9(A)に示すC−C線断面図であり、緩衝部材70の横断面を示している。 FIG. 8 is an enlarged cross-sectional view near the portion A shown in FIG. 7, showing the structure near the support portion 53. FIG. 9A is a vertical cross-sectional view of the cushioning member 70 provided on the support portion 53. FIG. 9B is a cross-sectional view taken along the line CC of FIG. 9A and shows a cross section of the cushioning member 70.

図8に示すように、ベース部材51には、仕切部材35に形成された支軸部37が挿入される支持穴53aが形成されている。詳しくは、ベース部材51には、前後方向に延在して少なくとも仕切部材35側が開口する略円筒形状の支持部53が形成されており、支持部53の内周側が支持穴53aとなる。そして、ベース部材51の支持穴53aに仕切部材35の支軸部37が緩衝部材70を介して嵌合することにより、ベース部材51が仕切部材35に支持されている。 As shown in FIG. 8, the base member 51 is provided with a support hole 53a into which the support shaft portion 37 formed in the partition member 35 is inserted. Specifically, the base member 51 is formed with a substantially cylindrical support portion 53 extending in the front-rear direction and having at least the partition member 35 side opened, and the inner peripheral side of the support portion 53 serves as a support hole 53a. Then, the support member 53 is supported by the partition member 35 by fitting the support shaft portion 37 of the partition member 35 into the support hole 53 a of the base member 51 via the buffer member 70.

緩衝部材70は、例えば、合成ゴム成形品等の弾性体であり、図9(A)及び(B)に示すように、略円筒形状の形態を成す嵌合部71と、嵌合部71の一端部近傍から外径側に環状に突設されたフランジ部73と、を有する。 The buffer member 70 is, for example, an elastic body such as a synthetic rubber molded product, and as shown in FIGS. 9A and 9B, the fitting portion 71 having a substantially cylindrical shape, and the fitting portion 71. And a flange portion 73 annularly protruding from the vicinity of one end portion toward the outer diameter side.

図8に示すように、緩衝部材70の嵌合部71は、ベース部材51の支持穴53aに嵌挿される。また、嵌合部71の内孔72に仕切部材35の支軸部37が嵌合する。そして、緩衝部材70のフランジ部73は、仕切部材35の主面とベース部材51とによって挟まれている。これにより、緩衝部材70の嵌合部71で支軸部37に対して半径方向の振動を減衰させ、フランジ部73で仕切部材35の主面に垂直な方向の振動を減衰させることができ、上下左右前後方向の振動を好適に抑えることができる。 As shown in FIG. 8, the fitting portion 71 of the cushioning member 70 is fitted into the support hole 53 a of the base member 51. Further, the support shaft portion 37 of the partition member 35 is fitted into the inner hole 72 of the fitting portion 71. The flange portion 73 of the cushioning member 70 is sandwiched between the main surface of the partition member 35 and the base member 51. As a result, the fitting portion 71 of the cushioning member 70 can dampen the vibration in the radial direction with respect to the support shaft portion 37, and the flange portion 73 can dampen the vibration in the direction perpendicular to the main surface of the partition member 35. It is possible to suitably suppress vibration in the up, down, left, right, front, and rear directions.

このように、ベース部材51が緩衝部材70を介して仕切部材35に固定されていることにより、送風機カバー60を駆動する駆動軸67(図7参照)からの振動が仕切部材35に伝播することを抑制して、騒音の増大を抑えることができる。 As described above, since the base member 51 is fixed to the partition member 35 via the cushioning member 70, the vibration from the drive shaft 67 (see FIG. 7) that drives the blower cover 60 is propagated to the partition member 35. Can be suppressed, and an increase in noise can be suppressed.

また、図9(B)に示すように、緩衝部材70の内孔72には、内側に向かって突出する凸部74が形成されている。即ち、図8及び図9を参照して、緩衝部材70は、仕切部材35の支軸部37に対向する内孔72の面から突設された凸部74を有し、凸部74において、仕切部材35に当接している。これにより、仕切部材35と緩衝部材70との接触面積を減らして、振動の伝播を抑制することができ、優れた制振効果が得られる。 Further, as shown in FIG. 9B, the inner hole 72 of the cushioning member 70 is formed with a convex portion 74 that protrudes inward. That is, with reference to FIG. 8 and FIG. 9, the cushioning member 70 has a convex portion 74 protruding from the surface of the inner hole 72 facing the support shaft portion 37 of the partition member 35. It is in contact with the partition member 35. As a result, the contact area between the partition member 35 and the cushioning member 70 can be reduced to suppress the propagation of vibration, and an excellent vibration damping effect can be obtained.

なお、凸部74の形状は特に限定されるものではなく、略直線状、略螺旋状、略点状等に形成されても良い。また、凸部74と同等の凸形状が緩衝部材70のベース部材51に対向する面、例えば、嵌合部71の外周面や、フランジ部73等に形成されても良い。これにより、ベース部材51と緩衝部材70との接触面積を減らして、制振効果を高めることができる。 The shape of the convex portion 74 is not particularly limited, and may be formed in a substantially linear shape, a substantially spiral shape, a substantially dot shape, or the like. Further, a convex shape equivalent to the convex portion 74 may be formed on the surface of the cushioning member 70 facing the base member 51, for example, on the outer peripheral surface of the fitting portion 71, the flange portion 73, or the like. As a result, the contact area between the base member 51 and the cushioning member 70 can be reduced, and the vibration damping effect can be enhanced.

図8に示すように、支持部53の外周は、送風機カバー60に形成された貫通孔61に摺動自在に嵌合している。これにより、送風機カバー60は、前後方向に往復移動可能となり、実線で示す開状態の位置から鎖線で示す閉状態の位置まで、送風機40に近づくように若しくは離れるように移動する。 As shown in FIG. 8, the outer periphery of the support portion 53 is slidably fitted in a through hole 61 formed in the blower cover 60. As a result, the blower cover 60 is capable of reciprocating in the front-rear direction, and moves toward or away from the blower 40 from the open position shown by the solid line to the closed position shown by the chain line.

支持部53の後端近傍は、段差状になっており、小径の送風機支持部54が形成されている。送風機支持部54には、略円筒形状の緩衝部材75が嵌め込まれ、緩衝部材75を介して送風機40のファンベース41が取り付けられる。詳しくは、緩衝部材75の外周面には、環状の凹溝が形成されており、該凹溝に、ファンベース41に形成された支持孔44が嵌め込まれている。 The vicinity of the rear end of the support portion 53 is stepped, and a blower support portion 54 having a small diameter is formed. A substantially cylindrical cushioning member 75 is fitted into the blower support portion 54, and the fan base 41 of the blower 40 is attached via the cushioning member 75. More specifically, an annular groove is formed on the outer peripheral surface of the cushioning member 75, and the support hole 44 formed in the fan base 41 is fitted into the groove.

つまり、支持部53は、ベース部材51を仕切部材35の支軸部37に固定するための機能と、ベース部材51に送風機40を固定するための機能と、を兼ね備えた構造である。このように、ベース部材51の支持部53によって仕切部材35と送風機40の双方を固定する構成により、ベース部材51の形状が複雑化することを抑えることができる。また、遮蔽装置50の前後方向の寸法を小さくすることができ、冷凍室4Aの収納容積を広く確保することができる。 That is, the support portion 53 has a structure that has both a function of fixing the base member 51 to the support shaft portion 37 of the partition member 35 and a function of fixing the blower 40 to the base member 51. As described above, the configuration in which both the partition member 35 and the blower 40 are fixed by the support portion 53 of the base member 51 can prevent the shape of the base member 51 from becoming complicated. Further, the size of the shielding device 50 in the front-rear direction can be reduced, and a large storage volume of the freezer compartment 4A can be secured.

図10は、遮蔽装置50の分解斜視図である。図10に示すように、ベース部材51の外周部近傍には、仕切部材35の後面から突設された係止片38の位置に対応して、3箇所の弾性部57が形成されている。 FIG. 10 is an exploded perspective view of the shielding device 50. As shown in FIG. 10, in the vicinity of the outer peripheral portion of the base member 51, three elastic portions 57 are formed corresponding to the positions of the locking pieces 38 protruding from the rear surface of the partition member 35.

弾性部57は、ベース部材51の外周部に沿って形成されたスリット58によって、ベース部材51の中央側に向かって弾性変形可能に構成されている。これにより、弾性部57は、ベース部材51が仕切部材35に組み付けられる際に、係止片38の爪部39(図11参照)の通過を許容するよう変形する。 The elastic portion 57 is configured to be elastically deformable toward the center side of the base member 51 by the slit 58 formed along the outer peripheral portion of the base member 51. As a result, the elastic portion 57 is deformed to allow passage of the claw portion 39 (see FIG. 11) of the locking piece 38 when the base member 51 is assembled to the partition member 35.

また、送風機カバー60の主面のベース部材51側には、ベース部材51の弾性部57の位置に対応して、ベース部材51側に突出する押圧部64が形成されている。押圧部64は、ベース部材51が仕切部材35に組み付けられる際に、ベース部材51の弾性部57近傍に当接してベース部材51を押圧する。なお、係止片38、弾性部57及び押圧部64の詳細については、図11を参照して後述する。 Further, a pressing portion 64 protruding toward the base member 51 side is formed on the main surface of the blower cover 60 on the side of the base member 51 corresponding to the position of the elastic portion 57 of the base member 51. When the base member 51 is assembled to the partition member 35, the pressing portion 64 contacts the vicinity of the elastic portion 57 of the base member 51 and presses the base member 51. Details of the locking piece 38, the elastic portion 57, and the pressing portion 64 will be described later with reference to FIG. 11.

また、ベース部材51には、ベース部材51の冷凍室4A側から冷却室13側に貫通する略角筒形状の配線経路部56が形成されている。これに対応して、送風機カバー60には、冷凍室4A側から冷却室13側に貫通して配線経路部56が挿通される配線孔65が形成されている。詳細については、図12を参照して後述する。 Further, the base member 51 is provided with a substantially rectangular tube-shaped wiring path portion 56 penetrating from the freezing chamber 4A side of the base member 51 to the cooling chamber 13 side. Corresponding to this, the blower cover 60 is formed with a wiring hole 65 penetrating from the freezing chamber 4A side to the cooling chamber 13 side and through which the wiring route portion 56 is inserted. Details will be described later with reference to FIG.

図11(A)は、図7に示すB部付近の拡大断面図であり、ベース部材51と係止片38との係合部付近を示している。図11(B)は、ベース部材51と係止片38との係合部付近を示す斜視図である。 FIG. 11A is an enlarged cross-sectional view near the portion B shown in FIG. 7, and shows the vicinity of the engaging portion between the base member 51 and the locking piece 38. FIG. 11B is a perspective view showing the vicinity of the engaging portion between the base member 51 and the locking piece 38.

図11(A)に示すように、仕切部材35の主面から突設された係止片38には、ベース部材51の外周部近傍に形成された弾性部57に係合する爪部39が形成されている。前述のとおり、ベース部材51の弾性部57は、スリット58が形成されることにより変形自在となっている。よって、ベース部材51が仕切部材35に組み付けられる際には、弾性部57がベース部材51の中央側に向かって弾性変形し、係止片38の爪部39が弾性部57の後面側まで押し込まれる。そして、係止片38が弾性部57に係合し、ベース部材51は、仕切部材35に固定される。このように、ベース部材51の外周部近傍に弾性部57が形成されることにより、ベース部材51を仕切部材35に取り付ける作業が容易になる。 As shown in FIG. 11(A), the locking piece 38 protruding from the main surface of the partition member 35 has a claw portion 39 that engages with an elastic portion 57 formed in the vicinity of the outer peripheral portion of the base member 51. Has been formed. As described above, the elastic portion 57 of the base member 51 is deformable by forming the slit 58. Therefore, when the base member 51 is assembled to the partition member 35, the elastic portion 57 elastically deforms toward the center side of the base member 51, and the claw portion 39 of the locking piece 38 is pushed to the rear surface side of the elastic portion 57. Be done. Then, the locking piece 38 engages with the elastic portion 57, and the base member 51 is fixed to the partition member 35. By forming the elastic portion 57 near the outer peripheral portion of the base member 51 in this manner, the work of attaching the base member 51 to the partition member 35 becomes easy.

図11(A)及び(B)に示すように、スリット58の周囲縁には、スリット58を取り囲むように該周囲縁から送風機カバー60側に延設された縁曲部59が形成されている。これにより、弾性部57近傍の剛性が高められ、弾性部57が前後方向に変形することが抑えられる。よって、ベース部材51を仕切部材35に組み付ける作業が容易になると共に、ベース部材51を仕切部材35に強固に固定することができる。 As shown in FIGS. 11A and 11B, at the peripheral edge of the slit 58, a curved edge portion 59 is formed so as to surround the slit 58 and extend from the peripheral edge toward the blower cover 60 side. .. As a result, the rigidity in the vicinity of the elastic portion 57 is increased, and the elastic portion 57 is prevented from being deformed in the front-rear direction. Therefore, the work of assembling the base member 51 to the partition member 35 becomes easy, and the base member 51 can be firmly fixed to the partition member 35.

また、図11(A)に示すように、ベース部材51の弾性部57の仕切部材35側の角部には、面取り形状の傾斜部57aが形成されている。これにより、ベース部材51が仕切部材35に組み付けられる際、弾性部57は、係止片38の爪部39に押されて、ベース部材51の中央側に変形し易くなる。よって、ベース部材51を組み付ける作業が容易になる。 Further, as shown in FIG. 11A, a chamfered inclined portion 57 a is formed at a corner of the elastic portion 57 of the base member 51 on the partition member 35 side. Thereby, when the base member 51 is assembled to the partition member 35, the elastic portion 57 is easily pushed by the claw portion 39 of the locking piece 38 and deforms toward the center of the base member 51. Therefore, the work of assembling the base member 51 becomes easy.

また、ベース部材51の係止片38によって固定される箇所に弾性変形自在な弾性部57が形成されることにより、遮蔽装置50の駆動軸67(図6参照)等から発生する振動や騒音が仕切部材35に伝播することを抑えることができる。即ち、弾性部57は、制振機能を発揮する。 In addition, since the elastic portion 57 that is elastically deformable is formed at a portion fixed by the locking piece 38 of the base member 51, vibration and noise generated from the drive shaft 67 (see FIG. 6) of the shielding device 50, etc. Propagation to the partition member 35 can be suppressed. That is, the elastic portion 57 has a vibration damping function.

また、弾性変形可能な弾性部57を設ける構成により、係止片38を大きく変形させる必要がなくなる。これにより、係止片38を短くすることができる。よって、遮蔽装置50の取り付け部付近の前後方向の寸法を小さくして、冷凍室4Aの収納容積を広く確保することができる。 In addition, the configuration in which the elastically deformable elastic portion 57 is provided eliminates the need to largely deform the locking piece 38. Thereby, the locking piece 38 can be shortened. Therefore, the dimension in the front-rear direction near the mounting portion of the shielding device 50 can be reduced, and a large storage volume of the freezer compartment 4A can be secured.

また、前述のとおり、送風機カバー60のベース部材51側の主面には、弾性部57近傍に対応する位置に、ベース部材51側に突出する押圧部64が形成されている。これにより、ベース部材51が仕切部材35に組み付けられる際、押圧部64がベース部材51の弾性部57近傍、詳しくは、縁曲部59の後端、に当接してベース部材51を押圧する。よって、ベース部材51の前後方向の変形が抑えられ、弾性部57を係止片38に容易に係合させることができる。 Further, as described above, the pressing portion 64 protruding toward the base member 51 is formed on the main surface of the blower cover 60 on the base member 51 side at a position corresponding to the vicinity of the elastic portion 57. Thereby, when the base member 51 is assembled to the partition member 35, the pressing portion 64 presses the base member 51 by abutting the vicinity of the elastic portion 57 of the base member 51, more specifically, the rear end of the curved edge portion 59. Therefore, the deformation of the base member 51 in the front-rear direction is suppressed, and the elastic portion 57 can be easily engaged with the locking piece 38.

つまり、予め一体的に組み立てられた遮蔽装置50の送風機カバー60付近を押さえて仕切部材35に向かって押し込むことにより、ベース部材51を係止片38に容易に係合させることができ、遮蔽装置50を容易に組み付けることができる。 That is, the base member 51 can be easily engaged with the locking piece 38 by pressing the vicinity of the blower cover 60 of the shield device 50 integrally assembled in advance and pushing it toward the partition member 35. The 50 can be easily assembled.

また、このような構成により、ベース部材51を押圧するために、弾性部57や係止片38の近傍に作業者の指等を挿入可能な空間を確保する必要がなくなる。よって、遮蔽装置50の周辺空間を狭くして、冷凍室4Aの収納容積を広く確保することができる。 Further, with such a configuration, it is not necessary to secure a space in which the operator's finger or the like can be inserted in the vicinity of the elastic portion 57 and the locking piece 38 in order to press the base member 51. Therefore, the space around the shielding device 50 can be narrowed to secure a large storage volume in the freezer compartment 4A.

また、図11(B)に示すように、係止片38の爪部39に対して反対側になる面には、係止片38と仕切部材35の主面とを連結するように形成されるリブ状の補強部38aが形成されても良い。これにより、係止片38の変形を押さえて、ベース部材51の脱落を防止することができる。 Further, as shown in FIG. 11B, the surface of the locking piece 38 opposite to the claw portion 39 is formed so as to connect the locking piece 38 and the main surface of the partition member 35. A rib-shaped reinforcing portion 38a may be formed. Accordingly, the deformation of the locking piece 38 can be suppressed, and the base member 51 can be prevented from falling off.

なお、上述の係止片38によるベース部材51の固定方法に加えて、若しくは代えて、ねじ等の締結部材によって、ベース部材51を仕切部材35に固定する方法を採用することも可能である。これにより、ベース部材51を強固に固定することができる。 In addition to or instead of the method of fixing the base member 51 by the locking piece 38 described above, a method of fixing the base member 51 to the partition member 35 by a fastening member such as a screw can be adopted. Thereby, the base member 51 can be firmly fixed.

図12は、配線経路部56付近を示す断面図である。図12に示すように、ベース部材51は、送風機カバー60の移動方向に沿って冷却室13側に延在してベース部材51の仕切部材35側と冷却室13側をつなぐ略筒状の配線経路部56を有する。配線経路部56は、送風機40のファンモータ43につながる配線77を通すための経路である。 FIG. 12 is a cross-sectional view showing the vicinity of the wiring route portion 56. As shown in FIG. 12, the base member 51 extends in the cooling chamber 13 side along the moving direction of the blower cover 60, and has a substantially cylindrical wiring that connects the partition member 35 side of the base member 51 and the cooling chamber 13 side. It has a path portion 56. The wiring route portion 56 is a route for passing the wiring 77 connected to the fan motor 43 of the blower 40.

送風機カバー60には、配線経路部56の外周に対応する形状で、配線経路部56が摺動自在に嵌合する配線孔65が形成されている。そして、配線孔65に配線経路部56が挿通されている。これにより、送風機カバー60は、実線で示す開状態の位置から鎖線で示す閉状態の位置まで、配線経路部56に沿って往復移動可能に構成される。 The blower cover 60 is provided with a wiring hole 65 having a shape corresponding to the outer periphery of the wiring path portion 56 and into which the wiring path portion 56 is slidably fitted. The wiring path portion 56 is inserted through the wiring hole 65. As a result, the blower cover 60 is configured to be capable of reciprocating along the wiring path portion 56 from the open position shown by the solid line to the closed position shown by the chain line.

上記の構成により、ベース部材51を仕切部材35に固定して送風性能を高める構成において、送風機カバー60の冷却室13側に配設されるファンモータ43への配線を、仕切部材35側から配線経路部56を経由させて送風機40側に通すことができる。そして、配線77が挿通された配線経路部56は、図示しないシール部材等によって塞がれる。具体的には、配線77が挿通された配線経路部56の内部またはベース部材51と仕切部材35との間に、シール部材として、例えば、合成樹脂製の発泡シート材等が設けられ、配線経路部56が塞がれる。または、配線経路部56の開口周囲に仕切部材35が直接的に当接して、仕切部材35によって配線経路部56が塞がれる構成でも良い。このような構成により、送風機カバー60の移動性を確保しつつ配線孔65の密封シール性能を高めて、送風機カバー60を閉じた際の暖気の漏れを抑制し、冷蔵庫1の冷却性能を向上させることができる。なお、駆動軸67を駆動するモータへの配線78は、仕切部材35とベース部材51との隙間を通り、ベース部材51の仕切部材35側からモータに接続されている。 With the above configuration, in the configuration in which the base member 51 is fixed to the partition member 35 to enhance the air blowing performance, the wiring to the fan motor 43 arranged on the cooling chamber 13 side of the blower cover 60 is wired from the partition member 35 side. It can be passed to the blower 40 side via the route portion 56. Then, the wiring path portion 56 through which the wiring 77 is inserted is closed by a seal member or the like (not shown). Specifically, for example, a synthetic resin foam sheet material or the like is provided as a sealing member inside the wiring path portion 56 in which the wiring 77 is inserted or between the base member 51 and the partition member 35. The part 56 is closed. Alternatively, the partition member 35 may directly contact the periphery of the opening of the wiring path portion 56 so that the wiring member 56 is closed by the partition member 35. With such a configuration, the mobility of the blower cover 60 is ensured, the sealing performance of the wiring hole 65 is enhanced, the leakage of warm air when the blower cover 60 is closed is suppressed, and the cooling performance of the refrigerator 1 is improved. be able to. The wiring 78 to the motor that drives the drive shaft 67 passes through the gap between the partition member 35 and the base member 51 and is connected to the motor from the partition member 35 side of the base member 51.

以上説明の実施形態では、送風機カバー60として、閉状態において、送風機40のファン42の前面及び側面全周を覆う形態を例示した。しかしながら、送風機カバー60の形態は、前述の例に限定されるものではない。例えば、送風機カバー60には、閉状態において、冷蔵室3等の特定の収納室に対して送風機40からの空気の流通を許容する開口部が形成されていても良い。このような構成の送風機カバー60と、冷蔵室ダンパ34やその他の図示しないダンパ等の組み合わせにより、各収納室を、それぞれの冷却負荷に応じて、独立して効率的に冷却することができる。 In the embodiment described above, as the blower cover 60, a form in which the front surface and the entire side surface of the fan 42 of the blower 40 are covered in the closed state is illustrated. However, the form of the blower cover 60 is not limited to the above example. For example, the blower cover 60 may be formed with an opening that allows the air from the blower 40 to flow into a specific storage chamber such as the refrigerating chamber 3 in the closed state. By combining the blower cover 60 having such a configuration, the refrigerating compartment damper 34, and other dampers (not shown) or the like, it is possible to efficiently and independently cool each storage chamber in accordance with each cooling load.

本発明は、上記実施形態に限定されるものではなく、その他、本発明の要旨を逸脱しない範囲で、種々の変更実施が可能である。 The present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the scope of the present invention.
