近年の冷蔵庫は、図6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(59)を設け、さらにその下部に、温度切替室(58)と図示しない製氷室とを併置し、最下方に冷凍室(60)を配置するタイプが多くなっている。   As shown in the longitudinal sectional view of FIG. 6 in recent years, a refrigerator room (55) having the highest frequency of use and a large volume is disposed at the top, and a refrigerator space similar to the refrigerator room (55) is provided below the refrigerator. Many types have a vegetable room (59) for storing vegetables, a temperature switching room (58) and an ice making room (not shown) in the lower part, and a freezer room (60) at the bottom. It has become.

そして、冷蔵室(55)の背部には冷蔵空間の冷却をおこなう冷蔵用冷却器(65)およびファン(70)をカバー体(66)を介して配置しており、下方における冷凍室(60)の背部に対応する位置には、温度切替室(58)や製氷室、冷凍室(60)などの冷凍空間を冷却する冷凍用冷却器(71)およびファン(72)を配設しており、本体下部の機械室に設けた圧縮機(73)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(65)(71)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(70)(72)によって各貯蔵空間に循環させていた(例えば、特許文献1参照)。   A refrigeration cooler (65) for cooling the refrigeration space and a fan (70) are arranged on the back of the refrigeration chamber (55) via a cover body (66), and the freezer compartment (60) below In the position corresponding to the back of the refrigeration unit, a refrigeration cooler (71) and a fan (72) for cooling the refrigeration space such as the temperature switching chamber (58), the ice making chamber, and the freezing chamber (60) are arranged. Refrigerant from the compressor (73) provided in the machine room at the bottom of the main body is alternately flown into the refrigeration and refrigeration coolers (65) (71) by the switching valve, and each is cooled to a predetermined temperature. The cool air was circulated to each storage space by each fan (70) (72) (see, for example, Patent Document 1).

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、前記温度切替室(58)や製氷室、野菜室(59)および冷凍室(60)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 its front opening closed with a pivotable door, and the temperature switching chamber (58), ice making room, vegetable room (59) and freezer room (60) are drawer type doors. It can be pulled forward by the container and rail.

そして、前記冷蔵室(55)背部の冷蔵用冷却器(65)や冷蔵用のファン(70)を設置している冷却器室の冷気ダクト(67)部分においては、前記特許文献1記載のように、冷蔵用冷却器(65)に対してファン(70)を冷気流の下流側に配置してファン(70)から冷気を冷蔵室(55)内に吹き出すか、逆に、特に図示しないが、特許文献2に記載のように、ファンを冷却器の上流側に配置して冷気を貯蔵室内からファンに吸い込み冷却器を介して室内に吹き出すかの仕様選択をおこなうが、いずれの場合もファン(70)は冷却器(65)の上部に配置することがほとんどである。   And in the cool air duct (67) part of the cooler room in which the refrigerator (65) for refrigerating and the fan (70) for refrigerating are installed at the back of the refrigerating room (55), In addition, the fan (70) is arranged downstream of the cold air flow with respect to the refrigeration cooler (65), and the cold air is blown out from the fan (70) into the refrigerating chamber (55). As described in Patent Document 2, a fan is arranged on the upstream side of the cooler, and the specification of whether the cold air is sucked into the fan from the storage chamber and blown out through the cooler is selected.

しかしながら、上記特許文献1および2記載の構成は、ともに冷蔵室(55)背部の最上部に冷蔵用のファン(70)が配置されるため、ファン(70)部分の奥行き設置寸法が大きくなってその分カバー体(66)が室内側に突出することになり、開扉時には、使用者の目の高さの近傍に前記突出部が位置することから使用者に圧迫感を与える弊害がある。また、突出部分に設置した棚(61)の奥行長さが突出部の分だけ短くなり、位置的により目立つことから室内容積が実際以上に狭く感じる不具合があった。   However, in the configurations described in Patent Documents 1 and 2, since the refrigeration fan (70) is arranged at the uppermost part of the back of the refrigeration room (55), the depth installation size of the fan (70) portion is increased. Accordingly, the cover body (66) protrudes to the indoor side, and when the door is opened, the protrusion is located in the vicinity of the height of the eyes of the user. In addition, the depth of the shelf (61) installed in the protruding portion is shortened by the amount of the protruding portion, and the position of the shelf is more conspicuous.

特許文献3については、該当部分である冷却器(85)およびファン(90)は冷蔵室(75)の背面下部に設置された構成であるが、前記冷却器(85)とファン(90)とは奥行き方向に重なり合っていることから、収納品載置部の奥行長さがその分短かくなり、食品収納容積を大きく減じるものであった。   Regarding Patent Document 3, the cooler (85) and the fan (90), which are the corresponding parts, are installed at the lower back of the refrigerating room (75), but the cooler (85), the fan (90), Since they overlap each other in the depth direction, the depth of the stored product placement portion is shortened accordingly, and the food storage capacity is greatly reduced.

本発明は上記の事情を考慮してなされたものであり、冷蔵室用のファンを目立たない位置に配置して冷蔵室の背面上部の突出を抑制し、その部分における棚の奥行長を長くして食品収納容積を拡大するとともに、使用者に圧迫感を与えることなく室内の広々感を得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 circumstances, and the fan for the refrigerator compartment is arranged in an inconspicuous position to suppress the protrusion of the upper rear portion of the refrigerator compartment, and the depth of the shelf in that portion is lengthened. It is an object of the present invention to provide a refrigerator that can increase the food storage volume and can provide a roomy feeling without giving a user a feeling of pressure.

上記課題を解決するために本発明の冷蔵庫は、冷蔵庫本体に配設した冷蔵室と、前記冷蔵室内の背部に設けられ冷蔵室を冷却する冷蔵用冷却器と、前記冷蔵室の背部に設けられ前記冷蔵用冷却器で冷却された冷気を冷蔵室内に送風する冷蔵用のファンと、前記冷蔵用冷却器からの除霜水を受ける露受樋と、少なくとも前記冷蔵用冷却器と前記冷蔵用のファンとを覆うカバー体とを備え、前記冷蔵用冷却器、前記冷蔵用のファン、前記露受樋をそれぞれ上部から順に配置したことを特徴とするものである。   In order to solve the above problems, a refrigerator according to the present invention is provided in a refrigerating room disposed in a refrigerator main body, a refrigerating cooler that is provided on a back part of the refrigerating room and cools the refrigerating room, and is provided on a back part of the refrigerating room. A refrigeration fan that blows cold air cooled by the refrigeration cooler into a refrigeration chamber, a dew receiving bowl that receives defrost water from the refrigeration cooler, at least the refrigeration cooler and the refrigeration cooler And a cover body covering the fan, wherein the refrigerator for refrigeration, the fan for refrigeration, and the dew receiving bowl are arranged in order from the top.

本発明によれば、冷蔵室の背面上部にはファンを設置しないので、背面上部に平坦部を形成することができ、突出部による圧迫感を抑制することができるとともに、ファンを目立たない位置に効果的に配置して冷蔵室内の広々感を得ることができる。   According to the present invention, since no fan is installed in the upper rear portion of the refrigerator compartment, a flat portion can be formed in the upper rear portion, and a feeling of pressure due to the protruding portion can be suppressed, and the fan can be placed in an inconspicuous position. It can be effectively arranged to provide a spacious feeling in the refrigerated room.

下部に配置した冷蔵室(5)以外の製氷室(7)、温度切替室(8)および野菜室(9)、冷凍室(10)などの貯蔵室は、冷蔵室(5)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、扉に固着するとともに容器を保持した支持枠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引き出し扉方式としている。   Storage rooms such as the ice making room (7), temperature switching room (8), vegetable room (9), freezer room (10), etc. other than the refrigerating room (5) arranged in the lower part of the storage room compared to the refrigerating room (5) From the ease of use due to its installation height and position, the container is fixed to the door and the support frame holding the container is slid back and forth with the rail member provided on the indoor wall surface, and is pulled out to the outside with the door opening operation. The drawer door system is used to store and take out food from the top opening.

前記冷蔵室(5)の背部には、幅広で高さ寸法の高い背壁を利用して比較的幅広で高さを高くした表面積とし、その分奥行き寸法である厚みを薄くしたフィン付きチューブタイプの冷蔵用冷却器(15)を配置している。この冷蔵用冷却器(15)の室内側には、合成樹脂パネルで形成したカバー体(16)を配し、冷蔵室(5)の背面全体をほぼ覆うことで冷蔵室(5)の背部を形成し、冷蔵用冷却器(15)の上部から左右両側に亙って冷蔵室(5)内に冷気を吐出する発泡スチロールなどの成形断熱材で形成した冷気ダクト(17)、およびその一部を分岐して下方の野菜室(9)に供給するVダクト(18)を設け、前記カバー体(16)の前記棚(11)の上部に対応する位置にそれぞれ冷気吹出口(19)を穿設している。そして、前記冷蔵用冷却器(15)の下方には、冷蔵室(5)内を循環した冷気を吸い込み、吹き上げる冷蔵用のファン(20)を設置している。   The back of the refrigerator compartment (5) is a finned tube type that has a relatively wide and high surface area by utilizing a wide and high back wall, and a correspondingly thin depth. The refrigeration cooler (15) is arranged. A cover body (16) formed of a synthetic resin panel is arranged on the indoor side of the refrigeration cooler (15), and covers the entire back surface of the refrigeration room (5) to cover the back of the refrigeration room (5). A cold air duct (17) formed of a molded heat insulating material such as foamed foam that discharges cold air into the refrigerator compartment (5) from the upper part of the refrigerator (15) to the left and right sides, and a part thereof. A V duct (18) that branches and supplies to the lower vegetable compartment (9) is provided, and a cold air outlet (19) is formed at a position corresponding to the upper part of the shelf (11) of the cover body (16). is doing. A refrigeration fan (20) is provided below the refrigeration cooler (15) for sucking and blowing in cool air circulated in the refrigerator compartment (5).

また、前記冷凍室(9)や製氷室(7)、温度切替室(8)などの冷凍貯蔵空間を冷却する冷凍用冷却器(21)およびファン(22)は、前記冷蔵用冷却器(15)と同様の熱交換器で構成されており、前記製氷室(7)と温度切替室(8)および野菜室(9)の背部に亙って配置されている。   Further, the refrigeration cooler (21) and the fan (22) for cooling the refrigeration storage space such as the freezer compartment (9), ice making chamber (7), temperature switching chamber (8), etc. ) And is arranged over the back of the ice making chamber (7), the temperature switching chamber (8) and the vegetable chamber (9).

各冷蔵および冷凍貯蔵空間は、前記冷蔵用および冷凍用冷却器(15)(21)や機械室に配置した圧縮機(23)などからなる冷凍サイクルにより冷却されるものであり、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冷凍サイクルを制御して運転し、前記冷蔵用および冷凍用のファン(20)(22)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(9)の冷蔵貯蔵空間、および低温側である冷凍室(9)や製氷室(7)などの冷凍貯蔵空間に供給し、各々を独立して所定温度に冷却制御している。   Each refrigeration and refrigeration storage space is cooled by a refrigeration cycle including the refrigeration and refrigeration coolers (15) and (21), a compressor (23) disposed in a machine room, and the like. ) And the freezer compartment (9), etc., are operated by controlling the refrigeration cycle based on a temperature detected by a temperature sensor (not shown), and the cooling and refrigerating fans (20) and (22) rotate to Supplying cold air generated in the chiller to the refrigerated storage space (5) and vegetable room (9) on the high temperature side, and the freezer storage space such as the freezing room (9) and ice making room (7) on the low temperature side Each of them is independently controlled to be cooled to a predetermined temperature.

冷蔵用や冷凍用の前記各冷却器(15)(21)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。   The refrigerators (15) and (21) for refrigeration and refrigeration are provided exclusively for refrigeration storage space and refrigeration storage space, respectively, -13 ° C for refrigeration and- By setting the evaporation temperature as close as possible to each corresponding storage space temperature of about 30 ° C., the refrigeration cycle efficiency is kept high and power saving operation is performed.

前記冷蔵用のファン(20)は、軸流ファンであって、前記低温容器(12)の背部に対向して配置され、図3に拡大縦断面図、図4にその横断面図を示すように、ファンケーシング(25)内にファン(20)を配置し、ファン(20)の羽根の外周部にベルマウス(26)を形成し、ベルマウス(26)の後部に吸込み空間(27)を形成してその側方に吸込み口(28)を設けるとともに、冷蔵室(5)内から吸い込んだ冷気を後方から前部に向かって吹き出し、前記ファンケーシング(25)上部のカバー体(16)に上方後部に傾斜するように形成した傾斜ガイド面(29)に沿って上方後部に吹き上げるように形成している。   The refrigeration fan (20) is an axial fan, and is disposed so as to oppose the back of the cryogenic vessel (12). FIG. 3 shows an enlarged longitudinal sectional view and FIG. 4 shows a transverse sectional view thereof. The fan (20) is placed in the fan casing (25), the bell mouth (26) is formed on the outer periphery of the fan (20) blade, and the suction space (27) is formed at the rear of the bell mouth (26). The suction port (28) is formed on the side of the cooling chamber (5), and the cool air sucked from the refrigerator compartment (5) is blown out from the rear toward the front, and the cover (16) at the top of the fan casing (25) is blown out. It is formed so as to blow up to the upper rear part along the inclined guide surface (29) formed to incline to the upper rear part.

吹き上げられた冷気は、カバー体(16)内に立設している冷蔵用冷却器(15)のフィン間を通って冷却されつつさらに上方に至り、前記それぞれの冷気吹出口(19)から冷蔵室(5)内に吹き出して冷却作用をおこなうものである。なお、前記各棚間に設けた冷気吹出口(19)は、上方ほど開口を大きくして上方からの冷気吹き出し量を多くし、トータルとして冷蔵室(5)内をより均一に冷却するようにしている。   The cold air blown up is further cooled while passing through the fins of the refrigeration cooler (15) standing in the cover body (16), and is refrigerated from the respective cold air outlets (19). It cools by blowing out into the chamber (5). In addition, the cold air outlet (19) provided between the shelves is larger in the upper part to increase the amount of cold air blown from the upper part, so that the inside of the refrigerator compartment (5) can be cooled more uniformly as a total. ing.

前記冷蔵用のファン(20)の背部のファンケーシング(25)と冷蔵室(5)の背壁(5a)との間隙の上方は冷蔵用冷却器(15)の設置空間に連通させ、下方はファン(20)の下部に位置する露受樋(30)に連通させており、冷蔵用冷却器(15)に付着し、除霜動作により融解した除霜水は、ファン(20)の天井面を形成するファンケーシング(25)の上面部に落下し、その背面をガイドとして流下し、前記露受樋(30)に導かれるように形成している。   The upper part of the gap between the fan casing (25) at the back of the refrigeration fan (20) and the back wall (5a) of the refrigeration room (5) communicates with the installation space of the refrigeration cooler (15). The defrost water that is in communication with the dew ridge (30) located at the bottom of the fan (20), adheres to the refrigeration cooler (15), and is melted by the defrosting operation is removed from the ceiling surface of the fan (20). The fan casing (25) is formed so that it falls onto the upper surface portion of the fan casing (25), flows down using the rear surface thereof as a guide, and is guided to the dew receiving bowl (30).

前記ファンケーシング(25)の上面の前端部には、冷蔵用のファン(20)から冷蔵用冷却器(15)への冷気の流れを損なわないように、前記傾斜ガイド面(29)に沿って後部上方へ傾斜するガイド片(31)を設けている。このガイド片(31)の後部上方への傾斜端部の突出長は、前記ファンケーシング(25)の前面部からの距離をaとした場合、この前面部から前記傾斜ガイド面(29)上方の冷蔵用冷却器(15)のフィン前端縁までの距離bを前記aより長くすることにより、除霜時における除霜水はフィン端縁から落下してもファン(20)部に侵入することなく、ファンケーシング(25)の天井面からその背面を伝って露受樋(30)に導かれ排水機構を介して外部に排水することができるものであって、排水経路を確保できるとともに、ファン(20)に除霜水が侵入して氷結することによりファンモーターがロックするなどの重大な問題発生を防止することができる。   The front end of the upper surface of the fan casing (25) is arranged along the inclined guide surface (29) so as not to impair the flow of cold air from the refrigeration fan (20) to the refrigeration cooler (15). A guide piece (31) that is inclined upward at the rear is provided. The protrusion length of the inclined end portion of the guide piece (31) toward the upper rear portion is a distance above the inclined guide surface (29) from the front portion when the distance from the front portion of the fan casing (25) is a. By making the distance b to the fin front end edge of the refrigeration cooler (15) longer than the a, defrost water at the time of defrosting does not enter the fan (20) even if it falls from the fin edge. The fan casing (25) can be led from the ceiling surface to the dew basin (30) and drained to the outside through the drainage mechanism. 20) It is possible to prevent serious problems such as the fan motor locking when defrost water enters and freezes.

したがって、前記冷蔵用のファン(20)設置部分の奥行き寸法は、上方の冷蔵用冷却器(15)やダクト(17)部より深くなるが、露受樋(30)をファン(20)の下方に位置させたことにより、露受樋(30)の分の奥行寸法を減じて概ねファン(20)の奥行長さ分とすることができるので冷蔵室(5)内側への突出長を抑制することができ、突出長を抑制した分、収納内容積を拡大することができる。   Therefore, the depth dimension of the refrigeration fan (20) installation part is deeper than the upper refrigeration cooler (15) and duct (17), but the dew ridge (30) is located below the fan (20). Since the depth of the dew receiving bowl (30) can be reduced to approximately the depth of the fan (20), the length of protrusion to the inside of the refrigerator compartment (5) is suppressed. Therefore, it is possible to expand the storage internal volume by suppressing the protruding length.

さらに、このファンケーシング(25)の傾斜ガイド面(29)の部分は、冷蔵室(5)の底面部分であって使用者の目の高さよりかなり下方の位置になるので、ファンケーシング(25)が室内側に突出していても視感的に目立つことがなく、使用者に圧迫感を与えることがないとともに、引き出し式である低温容器(12)の引き出し長さにも合致した構成とすることができ、低温容器(12)の天井板を形成する冷蔵室(5)の最下方の棚(11´)を傾斜ガイド面(29)に合致させることによって、棚(11´)の奥行長が深くなり食品などの収納量を増大させることができる。   Furthermore, since the portion of the inclined guide surface (29) of the fan casing (25) is a bottom portion of the refrigerator compartment (5) and is located at a position considerably below the eye level of the user, the fan casing (25) Even if it protrudes to the indoor side, it is not visually noticeable, does not give a feeling of pressure to the user, and conforms to the drawer length of the pull-out cryogenic container (12) The depth of the shelf (11 ') can be adjusted by matching the lowermost shelf (11') of the refrigerator compartment (5) forming the ceiling plate of the cryogenic container (12) with the inclined guide surface (29). It becomes deeper and the amount of food can be increased.

冷蔵室(5)の上方部における突出部をなくすことを目的として、奥行長が深くなる冷蔵用のファン(20)を室内底面部に設置し、従来とは逆に、冷蔵用冷却器(15)をファン(20)の上方に配置した場合には、冷蔵用冷却器(15)から滴下する除霜水を受けるために、冷蔵用冷却器(15)とファン(20)との間に露受樋(30)を設置すると、露受樋(30)の側部に冷気通過用のダクトを配置する必要を生じ、また、ファン(20)と露受樋(30)とを前後に重ね合わせて配置した場合にも、冷蔵室(5)内への突出長や突出部分の上下の範囲が大きくなるものであり、貯蔵内容積を減少させることになるが、上記構成によれば、奥行き寸法の増大を抑制することができるとともに、冷蔵用冷却器(15)の除霜水がファン(20)部分に侵入する不具合を生じることなくスムーズに露受樋(30)に導入させることができる。   In order to eliminate the protruding part at the upper part of the refrigerator compartment (5), a refrigerator fan (20) having a deeper depth is installed at the bottom of the room. ) Is placed above the fan (20), it is exposed between the refrigeration cooler (15) and the fan (20) to receive the defrosted water dripping from the refrigeration cooler (15). Installation of the receptacle (30) necessitates the arrangement of a duct for passing cold air on the side of the dew receptacle (30), and the fan (20) and dew receptacle (30) are overlapped on the front and back. Even if it is arranged, the projecting length into the refrigerator compartment (5) and the upper and lower range of the projecting part will be increased, and the storage volume will be reduced. Increase in the amount of water and the defrost water from the refrigeration cooler (15) enters the fan (20). It can be introduced into the dew 受樋 (30) smoothly without Jill.
