本発明は、冷気強制循環方式の冷蔵庫に関する。   The present invention relates to a cold air forced circulation refrigerator.

冷気強制循環方式の従来の冷蔵庫としては、特開平10−205967号公報(特許文献1)に記載されたものが知られている。以下、従来例における要部断面図である図5を参照しながら従来の冷蔵庫について説明する。   As a conventional refrigerator of the cold forced circulation system, a refrigerator described in JP-A-10-205967 (Patent Document 1) is known. Hereinafter, a conventional refrigerator will be described with reference to FIG.

断熱箱体27は、外箱28と、内箱29と、これら両箱28、29の間に充填された断熱材30とからなり、第1の区画壁31と第2の区画壁32とによって内部を上から冷蔵室33、冷凍室34、野菜室35に区画形成している。冷蔵室用冷気吐出風路36は第1の区画壁31に設けられている。温度制御装置37は、冷蔵室用冷気吐出風路36に開口した風路38と、この風路38内に設けたフラップ39の開閉により冷気量を制御するダンパー装置40とを備えている。断熱カバー41、42は、ダンパー装置40を収納し、風路38を構成している。化粧カバー43は断熱カバー42に設けられている。冷蔵室33への冷気吐出ダクト22は、冷蔵室用冷気吐出風路36と、フラップ39を介して開口した風路38とで、ほぼストレートに連通した風路を構成している。   The heat insulating box 27 includes an outer box 28, an inner box 29, and a heat insulating material 30 filled between the two boxes 28, 29, and includes a first partition wall 31 and a second partition wall 32. The interior is partitioned into a refrigerator compartment 33, a freezer compartment 34, and a vegetable compartment 35 from above. The cold air discharge air passage 36 for the refrigerator compartment is provided in the first partition wall 31. The temperature control device 37 includes an air passage 38 that opens to the cold air discharge air passage 36 for the refrigerator compartment, and a damper device 40 that controls the amount of cold air by opening and closing a flap 39 provided in the air passage 38. The heat insulating covers 41 and 42 accommodate the damper device 40 and constitute an air passage 38. The decorative cover 43 is provided on the heat insulating cover 42. The cool air discharge duct 22 to the refrigerating chamber 33 forms a substantially straight air passage with the cool air discharge air passage 36 for the refrigerating chamber and the air passage 38 opened through the flap 39.

冷却器10で冷却された冷気は、送風機11で第1の区画壁31に設けた冷蔵室用冷気吐出風路36から、温度制御装置37内に備えたフラップ39を介した風路38を通り、冷蔵室33への吐出口23から冷蔵室内に送られ、室内を冷却した後、冷蔵室戻り風路(図示せず)を通して冷却器10に戻る。また、冷却器10で冷却された冷気は、冷凍室吐出口13から冷凍室34内に送られ、冷凍室34内を冷却した後、冷凍室吸込口14から冷却器10に戻る。また、冷却器10で冷却された冷気は、冷気吐出ダクト22の途中で分岐し、野菜室吐出風路(図示せず)を通じて、野菜室35に送られ、野菜室35内を冷却した後、野菜室戻り風路(図示せず)を通して冷却器10に戻る。   The cold air cooled by the cooler 10 passes from the cold air discharge air passage 36 for the refrigerating room provided on the first partition wall 31 by the blower 11 through the air passage 38 via the flap 39 provided in the temperature control device 37. Then, it is sent from the discharge port 23 to the refrigerator compartment 33 into the refrigerator compartment, cools the interior of the compartment, and then returns to the cooler 10 through the refrigerator compartment return air passage (not shown). Further, the cool air cooled by the cooler 10 is sent from the freezer discharge port 13 into the freezer compartment 34, cools the inside of the freezer compartment 34, and then returns from the freezer compartment suction port 14 to the cooler 10. Moreover, after the cold air cooled by the cooler 10 is branched in the middle of the cold air discharge duct 22 and sent to the vegetable room 35 through the vegetable room discharge air passage (not shown), the inside of the vegetable room 35 is cooled, It returns to the cooler 10 through a vegetable room return air path (not shown).

送風機11は、庫内側に配置したファンと、背面側に配置した駆動部とからなっている。そして、送風機11のファンより吐出される冷気の通風路はファンの出口Zf2から冷気吐出風路36の入り口Zr2へ約直角に曲げられて形成されている。換言すれば、ファンの出口Zf2と冷気吐出風路36の入り口Zr2とが図5に示すようにクランク状の通路で連通されている。   The blower 11 includes a fan disposed on the inner side of the cabinet and a drive unit disposed on the back side. And the ventilation path of the cold air discharged from the fan of the blower 11 is bent from the outlet Zf2 of the fan to the inlet Zr2 of the cold air discharge air path 36 at a right angle. In other words, the outlet Zf2 of the fan and the inlet Zr2 of the cold air discharge air passage 36 are communicated with each other through a crank-shaped passage as shown in FIG.

冷気量を制御するダンパー装置40が冷蔵室33の背部にあり、ダンパー装置40を通過した冷気を冷蔵室用冷気吐出ダクト22と野菜室用冷気ダクトとに分岐する分岐部が冷蔵室33の背部にある。   A damper device 40 for controlling the amount of cold air is provided at the back of the refrigerator compartment 33, and a branch portion for branching the cold air that has passed through the damper device 40 into the cold air discharge duct 22 for the refrigerator compartment and the cold air duct for the vegetable compartment is the back of the refrigerator compartment 33.

特開平10−205967号公報JP-A-10-205967

しかしながら、従来の冷蔵庫では、送風機11のファンを庫内側にその駆動する駆動部を背面側にそれぞれ配置しているので、ファンが冷気吐出風路36より大きく前方に位置することとなり、冷気がファンの出口Zf2から冷気吐出風路36の入り口Zr2へ大きく曲げられる。これによって、風路損失が増大して省エネに不利となるという課題があった。また、ファンをできるだけ後方に位置させて冷蔵室用冷気吐出風路36への曲がりを小さくしようとすると、送風機11の駆動部も後方に位置させることとなり、送風機11の駆動部に対応する冷却器室背面壁を薄くする必要がある。冷却器室背面壁を薄くすることにより、この部分からの熱漏洩量が増加して省エネに不利となるばかりでなく、この部分の外箱外表面に結露の恐れが生じる、と言う課題が生ずる。   However, in the conventional refrigerator, since the drive unit for driving the fan of the blower 11 is arranged on the back side on the inside of the refrigerator, the fan is positioned larger than the cool air discharge air passage 36 and the cool air is fan. From the outlet Zf2 to the inlet Zr2 of the cool air discharge air passage 36. As a result, there is a problem that the air path loss increases and is disadvantageous for energy saving. If the fan is positioned as far back as possible to reduce the bending to the cold air discharge air passage 36 for the refrigerator compartment, the drive unit of the blower 11 is also positioned rearward, and the cooler corresponding to the drive unit of the blower 11 The back wall of the room needs to be thin. By thinning the back wall of the cooler room, the amount of heat leakage from this part increases, which is disadvantageous for energy saving, and there is a problem that condensation may occur on the outer surface of the outer box of this part. .

なお、従来の冷蔵庫では、送風機11より吐出される冷気の通風路がファンの出口Zf2から冷気吐出風路36の入り口Zr2へ約直角に曲げられて形成されているため、ファンの出口Zf2と冷気吐出風路36の入り口Zr2との間の通風路における風路抵抗が特に大きくなると言う課題があった。   In the conventional refrigerator, the cooling air flow path discharged from the blower 11 is bent from the fan outlet Zf2 to the inlet Zr2 of the cooling air discharge air path 36 at a right angle, so the fan outlet Zf2 and the cold air There was a problem that the air path resistance in the ventilation path between the discharge air path 36 and the entrance Zr2 was particularly large.

本発明の第1の目的は、送風機に対応する断熱箱体の壁厚を確保しつつ、送風機で強制循環される風路の風路抵抗を低減することができ、省エネに優れた冷蔵庫を提供することにある。   The first object of the present invention is to provide a refrigerator that is capable of reducing the air passage resistance of the air passage forcedly circulated by the blower while ensuring the wall thickness of the heat insulating box corresponding to the blower, and is excellent in energy saving. There is to do.

また、従来の冷蔵庫では、冷気量を制御するダンパー装置40が冷蔵室33の背部にあるため、ダンパー装置40を収納し且つ断熱カバー41,42及び化粧カバー43等よりなる温度制御装置37が冷蔵室33に突出し、冷蔵室33の定格内容積が突出した寸法分だけ減少してしまうという課題があった。   Further, in the conventional refrigerator, since the damper device 40 for controlling the amount of cold air is located at the back of the refrigerator compartment 33, the temperature control device 37 that houses the damper device 40 and includes the heat insulating covers 41, 42, the decorative cover 43, and the like is refrigerated. It protruded to the chamber 33, and the subject that the rated internal volume of the refrigerator compartment 33 decreased by the protruded dimension occurred.

さらには、ダンパー装置40を通過した冷気を冷蔵室用冷気吐出ダクト22と野菜室用冷気ダクトとに分岐する分岐部が冷蔵室33の背部にあるため、野菜室冷却不足等が発生した場合は、冷凍室34の背部に設けた冷気供給通路と共に、冷蔵室33の背部に設けたダンパー装置40及び分岐部を調査する必要がある。この調査は、冷凍室34の背部の仕切部材と、冷蔵室33の背部のダンパー装置40及び冷気吐出ダクト22とを取り外して行うものであるため、その取り外し作業や、調査・修理処置後の組み込み作業に非常に時間を要すると言う課題があった。   Furthermore, since the branch part which branches the cold air which passed the damper apparatus 40 into the cold air discharge duct 22 for cold storage rooms and the cold air duct for vegetable rooms is in the back part of the cold storage room 33, when vegetable room cooling shortage etc. generate | occur | produced In addition to the cool air supply passage provided in the back of the freezer compartment 34, it is necessary to investigate the damper device 40 and the branch provided in the back of the refrigerator compartment 33.

仕切部材61は、断熱材61bと、表面板61aと、ダンパー装置65と、送風機64と、マウスリングプレート62と、支持具64b及び係止具64cとを、予め互いに組み込んで、且つ、所定の外形寸法となるように構成してある。断熱材61bは、冷却器室57と冷凍室53とを区画し、必要な断熱性能を有している。表面板61aは、断熱材61bの庫内側に形成されている。ダンパー装置65は、送風機64の側方に位置して、断熱材61bに嵌合若しくは接着剤や図示しない係止具にて固定されている。マウスリングプレート62は、冷却器室57の庫内側を形成し、送風機64のマウスリング部62aを一体或いは別体にて有している。支持具64b及び係止具64cは、マウスリングプレート62に送風機64を固定するものである。   The partition member 61 includes a heat insulating material 61b, a surface plate 61a, a damper device 65, a blower 64, a mouth ring plate 62, a support tool 64b and a locking tool 64c in advance, and a predetermined member. It is comprised so that it may become an external dimension. The heat insulating material 61b partitions the cooler chamber 57 and the freezing chamber 53 and has necessary heat insulating performance. The surface plate 61a is formed on the inner side of the heat insulating material 61b. The damper device 65 is located on the side of the blower 64 and is fixed to the heat insulating material 61b by fitting or using an adhesive or a locking tool (not shown). The mouth ring plate 62 forms the inside of the cooler chamber 57, and has a mouth ring portion 62a of the blower 64 integrally or separately. The support tool 64 b and the locking tool 64 c fix the blower 64 to the mouth ring plate 62.

また、断熱材61b内には、冷蔵室冷却用送風ダクト72と、野菜室冷却用送風ダクト82及び冷蔵室帰還路ダクト76とが設けられている。従って、冷蔵室52や野菜室54の冷却不足等が発生した場合には、冷凍室53の背部に取り付け、取り外し可能に設置された仕切部材61を取り外すだけで、仕切部材61に設けられた、冷却機能に大きな影響をおよぼす送風機64、ダンパー装置65、冷蔵室冷却用送風ダクト72、野菜室冷却用送風ダクト82、及び冷蔵室帰還路ダクト76等を取り出して、点検、修理や交換が容易にできる。また、仕切部材61を取り外すことにより、冷却機能に大きな影響をおよぼす冷却器58や冷却器室57が露出するので、冷却器58や冷却器室57の点検、修理や交換が容易にできる。   Further, in the heat insulating material 61b, a cooling room cooling air duct 72, a vegetable room cooling air duct 82, and a refrigerating room return path duct 76 are provided. Therefore, when the cooling room 52 or the vegetable room 54 is insufficiently cooled, it is provided on the partition member 61 simply by removing the partition member 61 that is attached to the back of the freezer room 53 and detachably installed. Take out the blower 64, the damper device 65, the refrigeration room cooling air duct 72, the vegetable room cooling air duct 82, the refrigeration room return path duct 76, etc., which have a great influence on the cooling function, and can be easily inspected, repaired and replaced. it can. Further, by removing the partition member 61, the cooler 58 and the cooler chamber 57 that have a great influence on the cooling function are exposed, so that the cooler 58 and the cooler chamber 57 can be easily inspected, repaired, and replaced.

なお、表面板61aや、断熱材61b、ダンパー装置65、冷蔵室冷却用送風ダクト72、野菜室冷却用送風ダクト82、冷蔵室帰還路ダクト76、送風機64、マウスリングプレート62、支持具64b、及び係止具64c等の数多い部品を、それぞれに冷凍室53背部に組み込むと、その組み込み作業が非常に煩雑となると共に、数多い部品同士を組み合わせるための係止具やシール部材等が必要となる恐れが生じ、組み込み作業効率が落ち、冷蔵庫の生産性が低下する。本実施形態では、それらの課題を改善するために、上述した数多い部品同士を予め組み合わせて、所定の外形寸法に抑えられた仕切部材61として構成してある。   In addition, the surface plate 61a, the heat insulating material 61b, the damper device 65, the air duct 72 for cooling the refrigerator compartment, the air duct 82 for cooling the vegetable compartment, the refrigerator return duct 76, the blower 64, the mouth ring plate 62, the support 64b, When a large number of parts such as the locking tool 64c and the like are incorporated into the back of the freezer compartment 53, the assembling work becomes very complicated, and a locking tool, a seal member, and the like are required for combining a large number of parts. Fear arises, the efficiency of assembly work is reduced, and the productivity of the refrigerator is reduced. In the present embodiment, in order to improve these problems, the above-described many components are combined in advance, and configured as a partition member 61 that is suppressed to a predetermined outer dimension.

そして、送風機64は、図3に示すように、ファン64fを背面側、つまり、冷却器室背面57a側とし、駆動部64gを庫内側にして設置してある。かかる構成によって、送風機64に対応する部分の断熱厚さt6寸法を確保しつつ、冷却器室57にて生成した冷気を吸い込む側を冷気の吸入に必要な所定寸法t5を確保できるようになっている。換言すれば、従来例の送風機11の背部の断熱壁のような、外箱に結露の恐れがある断熱厚さとする必要がなく、しかも所定の冷気の吸引量を確保できるように、ファン64fの位置と駆動部64gの位置を従来例と反転設置して、吸入寸法t5と該部の断熱壁厚さ寸法t6を確保し易いように構成してある。また、ファンの吸込み側に、吸引を阻害する恐れのある従来例のような駆動部が介在しないので、ファンの吸引量を確保し易い構成となる。   As shown in FIG. 3, the blower 64 is installed with the fan 64f on the back side, that is, the cooler chamber back side 57a, and the drive unit 64g on the inside. With this configuration, it is possible to secure a predetermined dimension t5 necessary for sucking cold air on the side for sucking cold air generated in the cooler chamber 57 while securing the heat insulation thickness t6 dimension of the portion corresponding to the blower 64. Yes. In other words, it is not necessary to have a heat insulation thickness that may cause condensation on the outer box, such as the heat insulation wall on the back of the blower 11 of the conventional example, and the fan 64f can be secured so that a predetermined amount of cold air can be sucked. The position and the position of the drive part 64g are reversed from the conventional example, so that the suction dimension t5 and the heat insulation wall thickness dimension t6 of the part can be easily secured. In addition, since there is no drive unit on the suction side of the fan as in the conventional example that may impede suction, the fan suction amount can be easily secured.

そして、ファン64fの設置位置を、奥行き方向で、冷却器室背面57a近くに設けられた冷蔵室冷気通路74に近づけることにより、ファンの出口Zfと冷蔵室冷気通路入り口Zrとを連通する風路R1が、冷蔵室冷気通路74に曲がって入る角度θ1を小さくすることにより、該部を流れる冷気の通風抵抗を小さくするように構成してある。換言すれば、ファン64fと冷蔵室冷気通路74の風路線の延長仮想線R2との寸法L1を小さく設定することにより、角度θ1を小さくして、該部を流れる冷気の通風抵抗を小さくするように構成してある。   Then, the installation position of the fan 64f is brought closer to the refrigerator compartment cool air passage 74 provided near the cooler chamber rear surface 57a in the depth direction, thereby connecting the fan outlet Zf and the refrigerator compartment cold air passage entrance Zr. R1 is configured to reduce the airflow resistance of the cold air flowing through the portion by reducing the angle θ1 bent into the cold room cold air passage 74. In other words, by setting the dimension L1 between the fan 64f and the virtual imaginary line R2 of the air passage line of the refrigerator compartment cold air passage 74 to be small, the angle θ1 is made small so that the draft resistance of the cold air flowing through the portion is reduced. It is configured.

なお、角度θ1は、冷蔵室52の背面壁の厚さtrと冷凍室の背面壁の厚さtfとの関係、及び、ファン64fと冷蔵室冷気通路74との高さ方向における距離H1の大きさにより変化するが、上記L1寸法を小さく設定することにより、角度θ1を小さくできる。   The angle θ1 is the relationship between the thickness tr of the back wall of the refrigerating chamber 52 and the thickness tf of the back wall of the freezer compartment, and the distance H1 in the height direction between the fan 64f and the refrigerating chamber cool air passage 74. The angle θ1 can be reduced by setting the L1 dimension small.

また、ファン64fの出口Zfと冷蔵室冷気通路入り口Zrとを連絡する冷気供給通路を直線状とすることにより、該部の風路抵抗を低減する構成にしてある。この直線状とした通風路に通風路65bを有するダンパー装置65を設けることによって、冷気の流れがスムーズで且つ冷気によどみ等が生じない部分で、ダンパー装置65の風量制御ができる構成にしてある。   In addition, the cold air supply passage that connects the outlet Zf of the fan 64f and the cold room cold air passage inlet Zr is linear, thereby reducing the air path resistance of the portion. By providing the damper device 65 having the ventilation path 65b in the straight ventilation path, the flow rate of the damper apparatus 65 can be controlled at a portion where the flow of the cold air is smooth and the cold air does not stagnate. .

また、ファン64fの出口Zfとダンパー装置65の通風路65bとの距離L2寸法、及びダンパー装置65の通風路65bと冷蔵室冷気通路入り口Zrとの距離L3寸法を小さくして、該部の熱ロスを出来るだけ小さくなるように構成してある。   In addition, the distance L2 between the outlet Zf of the fan 64f and the ventilation path 65b of the damper device 65 and the distance L3 between the ventilation path 65b of the damper device 65 and the cold room cold air passage inlet Zr are reduced to reduce the heat of the part. The loss is made as small as possible.

本実施形態の構成及び効果を纏めると次の通りである。   The configuration and effects of this embodiment are summarized as follows.

Since the position of the fan 64f is close to the refrigerator compartment cool air passage 74 provided near the back surface of the cooler chamber 57 in the depth direction, the thickness of the heat insulating wall on the back surface portion of the cooler chamber 57 can be secured, The air path resistance of the air path forcedly circulated by the blower 64 can be reduced. Accordingly, it is possible to provide a refrigerator having a highly reliable air passage specification which is advantageous in terms of energy saving and does not cause stagnation of cold air.

また、ファン64fの出口にダンパー装置65を設け、ダンパー装置65を冷却器室57と冷凍室53とを区画する仕切部材61に設けると共に、ダンパー装置65の通風路を冷蔵室冷気通路74に奥行き方向で近づけたので、ダンパー装置65の通風路65bが冷蔵室冷気通路74に近くなると共に通風路65bが短くなり、通風路65bからの熱ロスの少ない冷蔵庫を提供できる。また、ダンパー装置65が冷蔵室52の背部に無いので、従来例のような冷蔵室52の背部の出っ張りがなくなり、冷蔵室内容積効率の良い冷蔵庫を提供できる。また、故障修理時に、仕切部材61を取り外すだけで、仕切部材61に設置された、冷却機能に大きな影響をおよぼすダンパー装置65を容易に取り出せるので、故障診断や修理・交換が容易にできる冷蔵庫が提供できる。   In addition, a damper device 65 is provided at the outlet of the fan 64f, the damper device 65 is provided in the partition member 61 that partitions the cooler chamber 57 and the freezing chamber 53, and the ventilation path of the damper device 65 is deep in the cold room air passage 74. Since the airflow path 65b of the damper device 65 is close to the refrigerating room cold air passage 74 and the airflow path 65b is shortened, the refrigerator with less heat loss from the airflow path 65b can be provided. Further, since the damper device 65 is not provided on the back of the refrigerating room 52, the protrusion of the back of the refrigerating room 52 as in the conventional example is eliminated, and a refrigerator with high volumetric efficiency in the refrigerating room can be provided. In addition, it is possible to easily remove the damper device 65 installed on the partition member 61 and having a great influence on the cooling function by simply removing the partition member 61 at the time of failure repair. Can be provided.

また、ファン64fの出口Zfと、冷蔵室冷気通路入り口Zrとを直線状とし、その間にダンパー装置65を設けたので、ファン64fから冷蔵室冷気通路間の風路抵抗が低減でき、冷気の流れがスムーズで、冷気によどみ等が生じない信頼性の高い風路仕様を提供できると共に、ダンパー装置65の風量制御機能が阻害されることのない冷蔵庫を提供できる。
