Description

本発明は、冷凍貯蔵空間および冷蔵貯蔵空間を有し、これらを冷却する冷却器と冷気循環ファンとを設けた冷蔵庫に関する。   The present invention relates to a refrigerator having a refrigerated storage space and a refrigerated storage space and provided with a cooler for cooling them and a cold air circulation fan.

近年の冷蔵庫は、図12にその縦断面図を示すように、最も使用頻度が多く容積の大きい冷蔵室(55)を最上部に配置し、その下部に製氷室(56)と図示しない温度切替室とを併置し、さらに、その下部に冷蔵室(55)と同様の冷蔵空間であり野菜類を収納する野菜室(58)を設け、最下方に冷凍室(59)を配置するタイプが多くなっている。   In recent refrigerators, as shown in the longitudinal sectional view of FIG. 12, the most frequently used and large-capacity refrigerator compartment (55) is arranged at the top, and the ice making chamber (56) and temperature switching not shown in the lower part. There are many types in which a room is placed side by side, a vegetable room (58) is provided in the lower part of the refrigeration room (55) to store vegetables, and a freezer room (59) is placed at the bottom. It has become.

そして、冷蔵室(55)の背面には冷蔵空間の冷却をおこなう冷蔵用冷却器(63)およびファン(65)を配置しており、下方における野菜室(58)の背部に対応する位置には、製氷室(56)や温度切替室、冷凍室(59)などの冷凍空間を冷却する冷凍用冷却器(64)およびファン(66)を配設しており、本体下部の機械室に設けた圧縮機(82)からの冷媒を切換弁によって前記冷蔵用および冷凍用冷却器(63)(64)に交互に流入させ、それぞれを所定温度に冷却して生成された冷気を各ファン(65)(66)によって各貯蔵空間に循環させていた。   A refrigeration cooler (63) and a fan (65) for cooling the refrigeration space are arranged on the back of the refrigeration room (55), and at a position corresponding to the back of the vegetable room (58) below. Refrigeration cooler (64) and fan (66) for cooling refrigeration spaces such as ice making chamber (56), temperature switching chamber, freezing chamber (59), etc., are installed in the machine room at the bottom of the main unit Refrigerant from the compressor (82) is alternately caused to flow into the refrigeration and refrigeration coolers (63) and (64) by a switching valve, and the generated cool air is cooled to a predetermined temperature for each fan (65). (66) circulated through each storage space.

なお、前記冷蔵室(55)は前面開口を回動式の扉で閉塞するとともに、前記野菜室(58)および製氷室(56)や温度切替室、冷凍室(59)は、引き出し式の扉と容器、そしてレールによって前方に引き出せるようにしている。   The refrigerator compartment (55) has a front door closed with a rotary door, and the vegetable compartment (58), the ice making compartment (56), the temperature switching compartment, and the freezer compartment (59) are drawer-type doors. It can be pulled forward by the container and rail.

前記冷蔵用および冷凍用冷却器(63)(64)はそれぞれ−13℃や−30℃近傍の低温度に冷却されることから、各冷却器と庫外側および貯蔵室内側とは的確に熱遮断する必要があり、その結果、内外との断熱壁厚が厚くなって、その分外形状に対する貯蔵室内の食品収納容積が小さくなる問題があった。   The refrigeration and refrigeration coolers (63) and (64) are cooled to low temperatures around -13 ° C and -30 ° C, respectively. As a result, there is a problem in that the heat insulation wall thickness between the inside and outside is increased, and the food storage capacity in the storage chamber with respect to the outer shape is reduced accordingly.

これに対し、貯蔵室内の収納容積効率を上げるために、通常ウレタンフォームなどの発泡断熱材からなる断熱壁(54)中に、断熱性能の高い所定厚みの真空断熱パネル(70)を配置し、断熱壁厚を薄くすることで収納容積を大きくしていた(特許文献1参照)。
特開2005−69448公報
On the other hand, in order to increase the storage volume efficiency in the storage chamber, a vacuum insulating panel (70) with a predetermined thickness and high heat insulating performance is arranged in a heat insulating wall (54) usually made of foam heat insulating material such as urethane foam, The storage volume was increased by reducing the thickness of the heat insulating wall (see Patent Document 1).
JP-A-2005-69448

しかしながら、前記真空断熱パネル(70)は発泡断熱材(54)に比較して非常に高価であるとともにこれを配設するだけで上記問題が解決する訳ではなく、特に最も大きな容量を必要とする冷蔵室(55)においては、室内後部に配置した冷却器(63)と断熱材が占める厚み寸法により、ダクトと合わせた後壁面全体が無効容積となり、依然として食品を収納できる有効容積を大きく減じていた。   However, the vacuum insulation panel (70) is very expensive as compared with the foam insulation (54) and the provision of the vacuum insulation panel (70) does not solve the above problem, and particularly requires the largest capacity. In the refrigerator compartment (55), due to the thickness dimension occupied by the cooler (63) placed in the rear of the room and the heat insulating material, the entire rear wall surface combined with the duct becomes an invalid volume, and the effective volume that can still contain food is greatly reduced. It was.

一方、設定温度の高い野菜室(58)の背部にはより低温度の冷凍用冷却器(64)が配されているため、両者間の大きな温度差に起因する熱漏洩によって温度影響を受けないように、室内側にはより厚みの大きい断熱材を設ける必要があり、室外側の断熱壁(54)とも合わせてその断熱厚さが厚くなることから、その分庫内の貯蔵容積を大きく減ずることになる欠点があった。   On the other hand, because the lower temperature freezer cooler (64) is placed at the back of the vegetable room (58), which has a high set temperature, it is not affected by temperature due to heat leakage caused by a large temperature difference between the two. Thus, it is necessary to provide a thicker heat insulating material on the indoor side, and since the heat insulating thickness is increased together with the heat insulating wall (54) on the outdoor side, the storage volume in the compartment is greatly reduced. There was a disadvantage that would be.

本発明は上記事情を考慮してなされたものであり、冷蔵用および冷凍用冷却器や冷却ファン、冷気ダクトなどを冷却貯蔵空間や断熱壁の位置を考慮して配置することで、コンパクト化をはかり、断熱厚やダクトスペースを効果的に配することで、その分室内側貯蔵空間の容積を増大することができる冷蔵庫を提供することを目的とする。   The present invention has been made in consideration of the above-mentioned circumstances, and the cooling and freezing coolers, cooling fans, cold air ducts, and the like are arranged in consideration of the position of the cooling storage space and the heat insulating wall, thereby reducing the size. An object of the present invention is to provide a refrigerator capable of increasing the volume of the indoor storage space by effectively arranging the scale, heat insulation thickness and duct space.

上記課題を解決するために本発明は、複数の独立室に断熱区画された冷蔵貯蔵空間および冷凍貯蔵空間をそれぞれ専用に冷却する冷蔵用および冷凍用冷却器と各冷却空間に冷気を循環するファンとを設けた冷蔵庫において、上下を断熱壁で仕切った複数の貯蔵区画の背面に前記冷蔵用と冷凍用冷却器、各ファンおよびダクトをユニット化して配設したことを特徴とするものである。   In order to solve the above-described problems, the present invention provides a refrigeration and refrigeration cooler that exclusively cools a refrigerated storage space and a refrigerated storage space that are insulated in a plurality of independent rooms, and a fan that circulates cold air to each cooling space. In the refrigerator provided with the above, the refrigeration and refrigeration coolers, the fans and the ducts are arranged as a unit on the back of a plurality of storage compartments whose upper and lower sides are partitioned by heat insulating walls.

本発明によれば、冷凍用と冷蔵用冷却器の近接配置による周辺機器構成のコンパクト化とともに、貯蔵室内側や本体外の断熱層の厚みをトータル的に減少させることが可能となり、その分庫内側貯蔵空間の容積を拡大することができる。   According to the present invention, it becomes possible to reduce the thickness of the heat insulation layer on the storage chamber side and the outside of the main body together with the compactness of the peripheral equipment configuration by the close arrangement of the freezing and refrigeration coolers. The volume of the inner storage space can be expanded.

以下、図面に基づき本発明の1実施形態について説明する。図1は、冷蔵庫の縦断面図、図2はその正面図であり、外箱(2)と内箱(3)、およびこれら内外箱間の空間部に充填された断熱材(4)からなる断熱箱体で形成された冷蔵庫本体(1)の内部を貯蔵空間として最上部に冷蔵室(5)、その下方に断熱仕切壁(10)を介して比較的小容積の自動製氷機を備えた製氷室(6)と温度切替室(7)を併設し、これらの下方には野菜室(8)、さらに最下方には冷凍室(9)をそれぞれ独立して配置している。前記野菜室(8)と冷凍室(9)との間にも断熱仕切壁(10)を設けており、各貯蔵室の前面開口には各々専用の扉を設けて開閉自在に閉塞している。   Hereinafter, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a longitudinal sectional view of a refrigerator, and FIG. 2 is a front view thereof. The refrigerator is composed of an outer box (2), an inner box (3), and a heat insulating material (4) filled in a space between these inner and outer boxes. The refrigerator main body (1) formed of a heat-insulated box body is used as a storage space with a refrigerator compartment (5) at the top and an automatic ice maker with a relatively small volume via a heat-insulating partition wall (10) below it. An ice making room (6) and a temperature switching room (7) are provided side by side, and a vegetable room (8) is disposed below them, and a freezing room (9) is further disposed below them. A heat insulating partition wall (10) is also provided between the vegetable compartment (8) and the freezer compartment (9), and a dedicated door is provided at the front opening of each storage compartment so as to be freely opened and closed. .

前記冷蔵室(5)は、最も収納容積が大きく使用頻度も高いため、前面開口部の両側に設けたヒンジで観音開き式の扉を枢支することで開口部を回動自在に閉塞しており、下部に配置した冷蔵室(5)以外の製氷室(6)および温度切替室(7)、野菜室(8)、冷凍室(9)などの貯蔵室は、冷蔵室に比べ収納容積が小さいこと、およびその設置高さ位置による使い勝手面から、扉に固着した支持枠に保持した容器を室内壁面に設けたレール部材で前後に摺動させ、開扉動作とともに室外に引き出して容器の上面開口から食品を収納し取り出する引き出し扉方式としている。   Since the refrigerator compartment (5) has the largest storage capacity and is frequently used, the opening is pivotally closed by pivotally supporting a double door with hinges provided on both sides of the front opening. The storage rooms such as the ice making room (6) and the temperature switching room (7), the vegetable room (8), and the freezing room (9) other than the refrigerating room (5) arranged in the lower part have a smaller storage capacity than the refrigerating room. From the ease of use depending on the installation height position, the container held on the support frame fixed to the door is slid back and forth with the rail member provided on the indoor wall surface, and is pulled out of the room together with the opening operation to open the upper surface of the container The drawer door system is used to store and take out food from.

しかして、本体中央部から下方に位置させた野菜室(8)の背部には、冷蔵室(5)や野菜室(8)の冷蔵貯蔵空間(11)を冷却する冷蔵用(以下、Rという。)冷却器(13)と、前記製氷室(6)や温度切替室(7)、冷凍室(9)などの冷凍貯蔵空間(12)を冷却する冷凍用(以下、Fという。)冷却器(14)とを、奥行き方向に対して前後に重なり合わせて設けている。   Thus, on the back of the vegetable compartment (8) positioned below from the center of the main body, the refrigerator compartment (5) and the refrigerated storage space (11) of the vegetable compartment (8) are cooled (hereinafter referred to as R). .) Refrigerator (13) and a refrigeration cooler (hereinafter referred to as F) for cooling the ice making chamber (6), the temperature switching chamber (7), the refrigeration storage space (12) such as the freezer compartment (9), etc. (14) are provided so as to overlap each other in the depth direction.

前記各貯蔵室は、図3に示すように、本体の下部背面に形成した機械室(20)に設置した圧縮機(22)、凝縮器(23)、冷媒流路の切換装置である三方弁(24)から、第1の絞り装置(25)と高温側であるR冷却器(13)とを直列に接続して前記圧縮機(22)に戻す回路を形成するとともに、前記三方弁(24)から前記第1の絞り装置(25)と高温側のR冷却器(13)からなる冷蔵側回路と並列に、第2の絞り装置(26)と低温側のF冷却器(14)、アキュムレータ(27)および逆止弁(28)を順に連結した冷凍側回路を接続した冷凍サイクル(21)により冷却されるものである。   As shown in FIG. 3, each of the storage chambers includes a compressor (22), a condenser (23), and a refrigerant flow switching device installed in a machine chamber (20) formed on the lower back surface of the main body. From (24), the first expansion device (25) and the R cooler (13) on the high temperature side are connected in series to form a circuit that returns to the compressor (22), and the three-way valve (24 ) To the refrigerating side circuit comprising the first throttling device (25) and the high temperature side R cooler (13), the second throttling device (26), the low temperature side F cooler (14), and the accumulator. It is cooled by a refrigeration cycle (21) connected to a refrigeration side circuit in which (27) and a check valve (28) are connected in order.

そして、冷蔵室(5)や冷凍室(9)などに設けられた図示しない温度センサーの検知温度により、前記三方弁(24)によって第1の絞り装置(25)とR冷却器(13)からなる冷蔵側回路、あるいは、第2の絞り装置(26)とF冷却器(14)、アキュムレータ(27)、および逆止弁(28)からなる冷凍側回路とに交互に流路を切り換えて冷媒を供給し冷却運転するとともに、前記R冷却器(13)およびF冷却器(14)の近傍にそれぞれ配置されたRファン(15)およびFファン(16)の回転によって、各冷却器で生成された冷気を高温側である冷蔵室(5)や野菜室(8)の冷蔵貯蔵空間(11)、および低温側である冷凍室(9)や製氷室(6)、温度切替室()など冷凍貯蔵空間(12)に供給し、各々を独立して所定温度に冷却制御している。   And by the detected temperature of the temperature sensor (not shown) provided in the refrigerator compartment (5), the freezer compartment (9), etc., the three-way valve (24) causes the first throttle device (25) and the R cooler (13) to The refrigerant is switched by switching the flow path alternately to the refrigeration side circuit or the refrigeration side circuit consisting of the second expansion device (26) and the F cooler (14), the accumulator (27), and the check valve (28). Is generated by each of the coolers by the rotation of the R fan (15) and the F fan (16) disposed in the vicinity of the R cooler (13) and the F cooler (14), respectively. Refrigerated storage space (11) in the cold room (5) and vegetable room (8) on the high temperature side, freezer room (9), ice making room (6), temperature switching room () on the low temperature side Supplying to the storage space (12), each is independently cooled to a predetermined temperature.

前記各冷却器(13)(14)は、それぞれ冷凍貯蔵空間用および冷蔵貯蔵空間用として専用に配設されたものであり、冷蔵用は−13℃、冷凍用は−30℃程度の各対応貯蔵空間温度に可能な限り近似する蒸発温度にすることにより、冷凍サイクル効率を高く保持して省電力運転をおこなうものである。   Each of the coolers (13) and (14) is dedicated for use in a refrigerated storage space and a refrigerated storage space, and is -13 ° C for refrigeration and -30 ° C for refrigeration. By setting the evaporation temperature as close as possible to the storage space temperature, the refrigeration cycle efficiency is kept high and power saving operation is performed.

具体的には、内外箱(3)(2)間に断熱材(4)を発泡充填する前処理段階での冷却器部分の横断面図である図4に示すように、高温側であるR冷却器(13)は前方の野菜室(8)側とし、低温側のF冷却器(14)は後部側に配設するものであり、これらRおよびF冷却器(13)(14)は、発泡スチロールなどの成型断熱材で形成された絶縁カバー(17)を介在して前後に併置し、さらに、前部のR冷却器(13)は正面からみて右側に、後方のF冷却器(14)は左側に偏倚するように左右にずらして配設している。   Specifically, as shown in FIG. 4 which is a cross-sectional view of the cooler portion in the pretreatment stage in which the heat insulating material (4) is foam-filled between the inner and outer boxes (3) and (2), the R on the high temperature side. The cooler (13) is on the front vegetable compartment (8) side, the low temperature side F cooler (14) is arranged on the rear side, and these R and F coolers (13) and (14) Insulating cover (17) made of molded heat insulating material such as polystyrene foam is placed side by side, and the front R cooler (13) is on the right side when viewed from the front, and the rear F cooler (14). Are shifted to the left and right so as to be biased to the left.

そして、前記図4よりも上方の製氷室(6)と温度切替室(7)の背面に対応する前記冷却ファン(15)(16)部分における横断面図であり、発泡断熱材(4)を充填した状態である図5、およびF冷却器(14)近傍の縦断面図である図6、さらにR冷却器(13)部分の縦断面図である図7から理解されるように、前方にあるR冷却器(13)は後方のF冷却器(14)より下方に位置させるとともに、RおよびFの各冷却器(13)(14)の上部に対応してRファン(15)とFファン(16)とを配置しており、F冷却器(14)で生成され、上昇してFファン(16)の後部から吸い込まれた冷凍側の低温冷気は、前部を吹き出し側として一部を前方の製氷室(6)および温度切替室(7)にそれぞれダンパー(18)を介して導入され、他の大部分の冷気は、前記絶縁カバー(17)によってF冷却器(14)の前面に形成されたF吹き出しダクト(29)から下方の冷凍室(9)に吹き出され、各室内を設定温度に冷却制御する。   And it is a cross-sectional view in the cooling fan (15) (16) portion corresponding to the back of the ice making chamber (6) and the temperature switching chamber (7) above the above FIG. 4, the foam insulation (4) As can be understood from FIG. 5 in a filled state, FIG. 6 which is a longitudinal sectional view in the vicinity of the F cooler (14), and FIG. 7 which is a longitudinal sectional view of the R cooler (13) portion, An R cooler (13) is positioned below the rear F cooler (14), and an R fan (15) and an F fan corresponding to the upper portions of the R and F coolers (13) and (14). (16) is arranged, and the low-temperature cold air on the freezing side generated by the F cooler (14), ascended and sucked from the rear part of the F fan (16) is partly used with the front part as the blowing side. The ice making chamber (6) and the temperature switching chamber (7) in front are respectively introduced via dampers (18), and most other cold air is Serial blown insulation from the cover (17) by F cooler F blowing duct formed on the front surface (14) (29) beneath the freezing compartment (9), cooling control each indoor set temperature.

製氷室(6)および温度切替室(7)を循環した冷気は、右側に偏倚して設けたR冷却器(13)の左側の断熱空間に形成したIリターンダクト(30)およびSリターンダクト(31)を通ってF冷却器(14)下方のF吸込み口(32)に導かれ冷凍室(9)を循環した冷気と合流してF冷却器(14)に戻る。   The cold air circulated through the ice making chamber (6) and the temperature switching chamber (7) is divided into an I return duct (30) and an S return duct ( 31) is passed to the F suction port (32) below the F cooler (14) and merged with the cold air circulated through the freezer compartment (9), and returns to the F cooler (14).

冷蔵空間側の冷却は、右側に設けたR冷却器(13)の上部から後方へ延びるダクトをファンへの吸込みダクト(33)として冷気をRファン(15)から上方に吹き出し、R吹き出しダクト(34)から冷蔵室(5)の背面全体に亙って幅広に形成した背面ダクト(35)内に流入し上昇して、上面や背面中央、背面側辺部などのR吹出口(36)から室内に吹き出し、これを所定温度に冷却する。   Cooling of the refrigeration space side is performed by using a duct extending rearward from the upper part of the R cooler (13) provided on the right side as a suction duct (33) to the fan, and blowing cool air upward from the R fan (15). 34) from the R air outlet (36) such as the upper surface, the center of the rear surface, and the side of the rear surface. It blows out into the room and cools it to a predetermined temperature.

冷蔵室(5)内を循環した冷気は、室内底部から前記R吹き出しダクト(34)の前部に前方に傾斜するように設けたR吸込みダクト(37)に吸い込まれ、温度切替室(7)の背部の絶縁カバー(17)に形成したVダクト(38)を介して野菜室(8)内に導入され、野菜室(8)内を循環冷却した冷気は、野菜室の下方からR冷却器(13)の下部に吸い込まれ、以後循環を繰り返すものである。   The cold air circulated in the refrigerator compartment (5) is sucked into the R suction duct (37) provided so as to incline forward from the bottom of the room to the front part of the R blowing duct (34), and the temperature switching chamber (7). The cold air introduced into the vegetable compartment (8) through the V duct (38) formed in the insulating cover (17) on the back of the circulatory and circulated and cooled in the vegetable compartment (8) is introduced into the R cooler from below the vegetable compartment. It is sucked into the lower part of (13) and repeats circulation thereafter.

前記構成により、R冷却器(13)からの冷気は、冷却器が配された背面幅方向の右側の位置から同じ側の上方へ吹き出され、背面ダクト(35)に流入するものであり、冷蔵室(5)内を循環後は前記R吹き出しダクト(34)の前部およびRファン(13)吸込み部の前部に形成した野菜室(8)へのVダクト(38)を流れるので、圧損が少なく、また相互に循環する冷気温が近似することから隣接するダクト間の厚みを薄くすることができ、効果的なダクト構成とすることができる。   With the above configuration, the cool air from the R cooler (13) is blown upward from the right side in the back width direction where the cooler is disposed, and flows into the back duct (35). After circulating in the chamber (5), it flows through the V duct (38) to the vegetable chamber (8) formed in the front part of the R blowing duct (34) and the front part of the R fan (13) suction part. In addition, since the cold temperatures circulating around each other are approximate, the thickness between adjacent ducts can be reduced, and an effective duct configuration can be obtained.

また、前記Rファン(15)から背面ダクト(35)へのR吹き出しダクト(34)とR吸込みダクト(37)とは、冷蔵室(5)と下方の製氷室(6)、温度切替室(7)との後部仕切壁を形成する成形断熱材(39)中に一体に設けられており、成形断熱材(39)をウレタンフォーム断熱材の発泡充填前の前処理段階で内箱(3)の背部から仕切壁(10)部に挿入して取り付けることにより、仕切壁(10)の間隔を確実に保持するとともに、ダクト(34)(37)の位置決めを容易にして内箱(3)に確実に固定することができる。   The R blow duct (34) and the R suction duct (37) from the R fan (15) to the rear duct (35) include a refrigerating chamber (5), a lower ice making chamber (6), and a temperature switching chamber ( 7) is integrally provided in the molded heat insulating material (39) forming the rear partition wall, and the molded heat insulating material (39) is placed in the inner box (3) in the pretreatment stage before foam filling of the urethane foam heat insulating material. By inserting and attaching to the partition wall (10) from the back of the door, the interval between the partition walls (10) is securely maintained, and the positioning of the ducts (34) and (37) is facilitated to the inner box (3). It can be fixed securely.

上記のように、R冷却器(13)とF冷却器(14)とを、野菜室(8)の背面において前後に重なり合わせ、それぞれを左右にずらして配置することにより、蒸発温度差が大きい各冷却器の双方への温度影響を極力小さくするとともに、各冷却器(13)(14)の上方にそれぞれの冷却器に対応する冷却ファン(15)(16)を併置し、互いのファンの冷気吹き出し方向を逆向きにしてFファン(15)は前方へ吹き出すようにしている。   As described above, the R cooler (13) and the F cooler (14) overlap each other on the back of the vegetable compartment (8), and are shifted to the left and right to increase the difference in evaporation temperature. In addition to minimizing the temperature effect on both coolers, the cooling fans (15) and (16) corresponding to each cooler are placed above each cooler (13) and (14), and The F fan (15) is blown forward with the cold air blowing direction reversed.

したがって、各冷却器(13)(14)で生成される冷気を対応する冷却ファン(15)(16)に良好な位置関係で流すことができ、Fファン(15)とF冷却器(16)の前面にはF吹き出しダクト(29)を形成し、絶縁カバー(17)を介してR冷却器(13)を配設するようにしたので、前記絶縁カバー(17)の断熱材の厚みを薄くすることができる。   Therefore, the cool air generated in each cooler (13) (14) can be flowed to the corresponding cooling fan (15) (16) in a good positional relationship, and the F fan (15) and the F cooler (16) Since the F blowout duct (29) is formed on the front surface of the, and the R cooler (13) is disposed through the insulating cover (17), the thickness of the heat insulating material of the insulating cover (17) is reduced. can do.

また、前側に設置したR冷却器(13)の側方における断熱壁中には、製氷室(6)および温度切替室(7)からのリターンダクト(30)(31)を設けており、室内側など他の箇所に設置することによる貯蔵室内容積の目減りを防ぐことができる。   In addition, in the heat insulating wall on the side of the R cooler (13) installed on the front side, there are return ducts (30) and (31) from the ice making chamber (6) and the temperature switching chamber (7). It is possible to prevent a decrease in the volume of the storage chamber due to installation in other places such as the inside.

前記R冷却器(13)およびF冷却器(14)は、各構成部品の分解斜視図である図8に示すように、F冷却器(14)の前面をカバーするFエバカバー(41)や前記絶縁カバー(17)を介し、R冷却器(13)の前面はRエバカバー(42)で覆ってエバ組立(40)とし、これを製氷室(6)と温度切替室(7)および野菜室(8)を構成する空間の背部に設置して、本体外から室内に導入させた前記冷凍サイクルの配管端部と接合する。このとき、前述のように、前方のR冷却器(13)は後方のF冷却器(14)より低位置に設置しているので、F冷却器(14)上部の配管接合および溶接作業を容易におこなうことができる。   The R cooler (13) and the F cooler (14) are, as shown in FIG. 8 which is an exploded perspective view of each component, an F EVA cover (41) covering the front surface of the F cooler (14), Through the insulating cover (17), the front of the R cooler (13) is covered with the R evaporator cover (42) to form an elevator assembly (40). This is the ice making chamber (6), temperature switching chamber (7) and vegetable chamber ( 8) and is joined to the pipe end of the refrigeration cycle introduced from the outside of the main body into the room. At this time, as described above, the front R cooler (13) is installed at a lower position than the rear F cooler (14), so that the pipe connection and welding work on the F cooler (14) is easy. Can be done.

そして、この状態で冷却器(13)(14)の上部に、各冷却ファン(15)(16)が位置するように、図9に分解斜視図で示す各冷気吸込み口や吹出口、および各室への冷気ダクトを設けたエバカバー組立(43)を組み込むことで、裏面の冷却器とファン側からみた図10に示す状態になり、組立品全体の前面を前カバー(44)で覆うことによって冷却器ユニット部の組立を完了する。   In this state, the cooling fans (15) and (16) are positioned above the coolers (13) and (14) so that the cooling air inlets and outlets shown in the exploded perspective view of FIG. By incorporating the EVA cover assembly (43) with a cool air duct to the chamber, the state shown in Fig. 10 is seen from the rear cooler and fan side, and the front of the entire assembly is covered with the front cover (44) Complete the assembly of the cooler unit.

なお、(45)は、ファンダクト組立体であり、RおよびF冷却ファン(15)(16)のベルマウスを形成するとともに冷気の吸込みおよび吹き出しダクトを形成して一体に組み立てたものであり、前記エバカバー組立の後方部に組み込まれるものである。   In addition, (45) is a fan duct assembly, which forms a bell mouth of the R and F cooling fans (15) and (16) and forms a cold air suction and blowout duct and is assembled integrally. It is incorporated in the rear part of the above-mentioned cover cover assembly.

野菜室(8)と上部室とを区分する仕切壁(46)、および上部の製氷室(6)と温度切替室(7)とを区分する仕切壁は、前記冷却器ユニットを背面に組み込んだ後に組み立てられる。   The partition wall (46) that separates the vegetable compartment (8) from the upper chamber, and the partition wall that separates the upper ice making chamber (6) and the temperature switching chamber (7) incorporate the cooler unit on the back. It will be assembled later.

したがって上記構成によれば、冷蔵庫の断熱貯蔵空間を構成する際に、容積の大きな冷蔵室(5)と最下方の貯蔵室、本実施例の場合は冷凍室(9)との断熱仕切壁(10)を現場発泡方式により形成してキャビネットとしての剛性を得るようにし、上下を前記断熱壁(10)で仕切った製氷室(6)と温度切替室(7)および野菜室(8)の背面を、図11に示すように、ひとつの区画として、この部分に前記RおよびF冷却器(13)(14)とファン(15)(16)、ダクトを含む冷却器室を構成する部材を、エバ組立(40)やエバカバー組立(43)としてユニット化して配設することができ、元来多くの部品群からなる冷却機器部品を簡素化し、組み立て作業を容易にして所定部位に精度よく組み込むことができるばかりでなく、各冷却器(13)(14)と冷凍サイクルとの配管接続、およびファン(15)(16)の電気接続などを比較的広い空間内で容易に且つ確実におこなうことができる。   Therefore, according to the said structure, when comprising the heat insulation storage space of a refrigerator, the heat insulation partition wall (5) and the lowermost storage room (in the case of a present Example, freezer compartment (9)) are comprised. 10) is formed by an on-site foaming system to obtain rigidity as a cabinet, and the ice making room (6), the temperature switching room (7), and the back of the vegetable room (8), which are separated from each other by the heat insulating wall (10) As shown in FIG. 11, the members constituting the cooler chamber including the R and F coolers (13) and (14), the fans (15) and (16), and the duct are formed as one section as shown in FIG. It can be installed as a unit as an EVA assembly (40) or an EVA cover assembly (43), simplifying the cooling equipment parts originally composed of many parts groups, facilitating the assembly work, and assembling with high precision into the specified part As well as each cooler (13) (14) Piping connection with the refrigeration cycle and electric connection of the fans (15) and (16) can be easily and reliably performed in a relatively wide space.

またユニットとして一体化することで各部品の配置が集積化され、省スペース効果が得られものであり、さらに、ユニット化により運搬も容易になって製造性やサービス作業を効率化することができる。   Also, by integrating them as a unit, the arrangement of each component is integrated, and a space saving effect is obtained. Furthermore, the unitization facilitates transportation and improves the productivity and service work efficiency. .

そしてまた上記構成により、従来は冷蔵室(5)の背面に配設していたR冷却器(13)をF冷却器(14)とともに配置することで、冷蔵室(5)の背部における冷却器設置のための空間を必要とせず、背面ダクト(35)は、冷蔵室(5)の背面全体を使用することが可能であることから、特に奥行き寸法として、冷却器の厚みおよび冷却器と室内との断熱壁厚で50mmを要していた厚み寸法を背面ダクト(35)を設置するための15mmまで圧縮して必要とする所定の風路断面積を得ることが可能となる。   In addition, with the above configuration, the R cooler (13) that has been conventionally arranged on the back surface of the refrigerator compartment (5) is arranged together with the F cooler (14), so that the cooler at the back of the refrigerator compartment (5). Since the space for installation is not required and the back duct (35) can use the entire back surface of the refrigerator compartment (5), the thickness of the cooler and the cooler It is possible to obtain the required predetermined air passage cross-sectional area by compressing the thickness dimension of 50 mm required for the heat insulation wall thickness to 15 mm for installing the rear duct (35).

したがって、この厚み寸法の圧縮分を冷蔵室(5)の奥行き寸法として増すことにより冷蔵室(5)容積を格段に大きくすることができ、有効内容積が400L程度の大型冷蔵庫において、有効な収納容積を数10L拡大することができるものである。   Therefore, the volume of the refrigerator compartment (5) can be remarkably increased by increasing the compressed portion of this thickness dimension as the depth dimension of the refrigerator compartment (5), and effective storage is achieved in a large refrigerator having an effective internal volume of about 400L. The volume can be increased by several tens of liters.

さらに、上記実施例構成によれば、前側に配置したR冷却器(13)の前面は、野菜室(8)であり、双方の温度差が比較的小さい関係に配置したことから、野菜室(8)とRF各冷却器(13)(14)とを最適な断熱厚関係にすることができ、前カバー(44)表面の氷結を防止するための発泡スチロールなどからなる断熱材を設けず、シート状の樹脂成形体からなる前記前カバー(44)のみで覆うようにしている。したがってこの部分においても断熱部材の厚み寸法を不要として、その分野菜室(8)としての奥行き寸法の増加が可能となり、室内貯蔵空間の容積を拡大することができる。   Furthermore, according to the said Example structure, since the front surface of R cooler (13) arrange | positioned at the front side is a vegetable room (8), and arrange | positioned in the relationship where both temperature differences are comparatively small, 8) and the RF coolers (13) and (14) can be in an optimum heat insulation thickness relationship, and the front cover (44) is not provided with a heat insulating material made of foamed polystyrene or the like for preventing freezing on the surface. It is made to cover only with the said front cover (44) which consists of a shape-like resin molding. Therefore, even in this portion, the thickness dimension of the heat insulating member is unnecessary, and the depth dimension of the vegetable room (8) can be increased accordingly, and the volume of the indoor storage space can be expanded.

なお、前カバー(44)の表面温度がR冷却器(13)などの影響を受けて低下し、結露や氷結の可能性がある場合は薄肉の断熱シートを介在させるようにすればよいものであり、また、図7に示すように、前カバー(44)の前面の下方に露受け樋(47)を一体に形成し、流下する結露水を受けて前カバー(44)裏面に導き、R冷却器(13)の排水樋(48)に流すようにしてもよく、さらに、特に図示しないが、前カバー(44)のR冷却器(13)側に小容量のヒーターを配設してR冷却運転後に通電し、野菜室(8)の高湿度雰囲気による露付きを防止するとともにR冷却器(13)の除霜に寄与させるようにしてもよい。   If the surface temperature of the front cover (44) drops due to the influence of the R cooler (13), etc., and there is a possibility of condensation or icing, a thin insulation sheet should be interposed. As shown in FIG. 7, a dew receiving bowl (47) is integrally formed below the front surface of the front cover (44), receives condensed water flowing down, and is guided to the back surface of the front cover (44). It may be allowed to flow through the drainage basin (48) of the cooler (13), and although not particularly shown, a small-capacity heater is provided on the R cooler (13) side of the front cover (44) to provide an R You may make it contribute to defrosting of R cooler (13) while energizing after cooling operation, preventing dew condensation by the high humidity atmosphere of a vegetable room (8).

また、図6に示すように、R冷却器(13)およびその裏面の断熱壁(17)は、前方の野菜室(8)に設置した野菜容器(8a)の背面傾斜面に合わせて傾斜させており、このことによって、傾斜による野菜室内の容器(8a)の収納容積を減らすことなく、底面における投影面積分だけ、F吹き出しダクト(29)の奥行き開口寸法(図6中A)を増やすことができる。さらに、その下方におけるF冷却器(14)への吸込み口(32)としての開口面積(図6中B)も拡げることができ、冷気のダクト内循環効率を向上させることができる。   Moreover, as shown in FIG. 6, R cooler (13) and the heat insulation wall (17) of the back surface are inclined according to the back inclined surface of the vegetable container (8a) installed in the front vegetable compartment (8). Therefore, the depth opening dimension (A in FIG. 6) of the F blowing duct (29) is increased by the projected area on the bottom without reducing the storage capacity of the container (8a) in the vegetable room due to the inclination. Can do. In addition, the opening area (B in FIG. 6) as the suction port (32) to the F cooler (14) below it can be expanded, and the circulation efficiency of cold air in the duct can be improved.

なお、上記実施形態においては、各貯蔵室のレイアウトを最上部に冷蔵室(5)、次いで製氷室(6)と温度切替室(7)とを併置し、その下部に野菜室(8)、最下部に冷凍室(9)のように配置したが、本発明はこれに限るものではない。   In the above embodiment, the storage room has a refrigerator compartment (5) at the top, followed by an ice making room (6) and a temperature switching room (7), and a vegetable room (8) at the bottom. Although arrange | positioned like the freezer compartment (9) in the lowest part, this invention is not limited to this.

本発明は、冷凍貯蔵空間および冷蔵貯蔵空間を個々に冷却する冷却器と冷気循環ファンとを設けた冷蔵庫に利用することができる。   INDUSTRIAL APPLICABILITY The present invention can be used for a refrigerator provided with a cooler that cools a frozen storage space and a refrigerated storage space and a cold air circulation fan.
