Description

本発明は、冷凍室と冷蔵室を備える冷蔵庫に関する。 The present invention relates to a refrigerator including a freezer compartment and a refrigerator compartment.

近年、野菜を切って冷凍室で保存し、調理の時にはここから取り出して野菜を使うことが行われている。そのため、野菜室の容積を減らして冷凍室の容積を大きくする要求がある。 In recent years, it has been practiced to cut vegetables and store them in a freezer, and then take them out of the vegetables and use them when cooking. Therefore, there is a demand for reducing the volume of the vegetable compartment and increasing the volume of the freezing compartment.

また、特許文献１には、冷凍室と冷蔵室に冷気を送風するファンに、ファンカバーをかけることにより省電力化を図る技術が記載されている。ヒータをつける除霜期間にファンカバーを閉じ、庫内に暖気が流れないようにするものである。 Further, Patent Document 1 describes a technique for saving power by attaching a fan cover to a fan that blows cool air to a freezer compartment and a refrigerator compartment. During the defrosting period when the heater is turned on, the fan cover is closed to prevent warm air from flowing into the refrigerator.

特許第６２５４４０４号Patent No. 6254404

ファン及びファンカバーが設けられるファン遮蔽装置は、冷凍室の背面に設置される。したがって、ファン遮蔽装置の大きさは、冷凍室の容積を圧迫する。また、冷凍室の背面には冷却器であるエバポレータ、除霜用のヒータが設置される。冷凍室を冷蔵庫最下部に設けようとすると、冷蔵庫下部のコンプレッサが設置される機械室が、エバポレータ、ヒータの設置場所を圧迫してしまい、ますます冷凍室の容積が小さくなる。 The fan shield device provided with the fan and the fan cover is installed on the back surface of the freezer compartment. Therefore, the size of the fan shield presses the volume of the freezer compartment. Further, an evaporator that is a cooler and a heater for defrosting are installed on the back surface of the freezer compartment. If the freezer is to be installed at the bottom of the refrigerator, the machine room where the compressor at the bottom of the refrigerator is installed puts pressure on the evaporator and heater installation locations, and the volume of the freezer becomes smaller and smaller.

そこで、本発明は、ファン遮蔽装置が設けられる冷蔵庫において、冷凍室の容積を増加することを目的とする。また、本発明は、ファン遮蔽装置を設けることで、省電力な冷蔵庫を提供することを目的とする。さらに、本発明は、縦長のエバポレータを冷凍室背面に配置することにより、冷却効率がよい冷蔵庫を提供することを目的とする。 Therefore, it is an object of the present invention to increase the volume of a freezer in a refrigerator provided with a fan shield device. Another object of the present invention is to provide a power-saving refrigerator by providing a fan shield device. A further object of the present invention is to provide a refrigerator having good cooling efficiency by disposing a vertically long evaporator on the back surface of the freezer compartment.

（冷蔵庫全体の構成について）
図１は、本発明の１つの実施形態における冷蔵庫の概略図である。図１を参照しながら本発明の冷蔵庫全体の構成を説明する。 (About the structure of the entire refrigerator)
FIG. 1 is a schematic diagram of a refrigerator in one embodiment of the present invention. The configuration of the entire refrigerator of the present invention will be described with reference to FIG.

図１に示すように、本発明の１つの実施形態の冷蔵庫１０１は、その内部に食品等の貯蔵ができる冷蔵庫本体１０３を備える。冷蔵庫本体１０３は、その前方の開口を開閉する扉１０５、１０７を備える。扉１０５は冷蔵室を開閉し、扉１０７は冷凍室１２０５を開閉する。 As shown in FIG. 1, a refrigerator 101 according to one embodiment of the present invention includes a refrigerator main body 103 capable of storing food or the like therein. The refrigerator main body 103 includes doors 105 and 107 that open and close an opening in front of the refrigerator main body 103. The door 105 opens and closes the refrigerating room, and the door 107 opens and closes the freezing room 1205.

（冷蔵庫の内部の構成について）
図２は、本発明の１つの実施形態における冷蔵庫１０１の扉を開放した正面図である。扉の記載は省略してある。図３は、本発明の１つの実施形態における冷蔵庫１０１である図２のＡ−Ａ断面図である。図２及び図３を参照しながら、冷蔵庫１０１の内部の構成を説明する。 (About the internal structure of the refrigerator)
FIG. 2 is a front view in which the door of the refrigerator 101 in one embodiment of the present invention is opened. The description of the door is omitted. FIG. 3 is a sectional view taken along the line AA of FIG. 2 showing the refrigerator 101 according to the embodiment of the present invention. The internal configuration of the refrigerator 101 will be described with reference to FIGS. 2 and 3.

図２に示すように、冷蔵庫本体１２０１は、冷蔵用の冷気が送風される、冷蔵食品を貯蔵する冷蔵室１２０７と野菜室１２０９とを備える冷蔵室１２０３と、冷凍用の冷気が送風される冷凍室１２０５を有する。冷蔵庫本体１２０１は、冷凍室１２０５が最下部に設けられ、冷凍室１２０５の上に野菜室１２０９が設けられ、野菜室１２０９の上に冷蔵食品を貯蔵する冷蔵室１２０７が設けられる。 As shown in FIG. 2, the refrigerator main body 1201 is provided with a refrigerating room 1203 for storing refrigerated foods, to which cold air for refrigerating is blown, and a refrigerating room 1203 for refrigerating, to which cold air for freezing is blown. It has a chamber 1205. The refrigerator main body 1201 is provided with a freezing compartment 1205 at the bottom, a vegetable compartment 1209 is provided on the freezing compartment 1205, and a refrigerating compartment 1207 for storing refrigerated food is provided on the vegetable compartment 1209.

図３に示すように、冷凍室１２０５の背面には、下部にコンプレッサが設置される機械室３０１が配置される。冷凍室背面の機械室３０１の上には、ヒータ３１１が配置される。冷凍室背面のヒータ３１１の上には、冷却器であるエバポレータ３０３が配置される。 As shown in FIG. 3, a machine room 301 in which a compressor is installed in the lower part is arranged on the back surface of the freezing room 1205. A heater 311 is arranged on the machine room 301 on the rear side of the freezing room. An evaporator 303, which is a cooler, is arranged on the heater 311 on the back surface of the freezing compartment.

機械室３０１は、冷蔵庫１０１の重心を下げ、冷蔵庫１０１の設置を安定化させるために冷蔵庫１０１の下部に置かれる。しかしながら、この部分は、冷蔵庫１０１の保存室の容積を圧迫してしまう。本実施の形態は、冷凍室１２０５を冷蔵庫１０１の最下部に配置するため、機械室３０１が冷凍室１２０５の容積を圧迫する。 The machine room 301 is placed under the refrigerator 101 to lower the center of gravity of the refrigerator 101 and stabilize the installation of the refrigerator 101. However, this portion presses the volume of the storage chamber of the refrigerator 101. In this embodiment, since the freezing compartment 1205 is arranged at the bottom of the refrigerator 101, the machine room 301 presses the volume of the freezing compartment 1205.

エバポレータ３０３は、冷凍室１２０５及び冷蔵室１２０３を冷却する冷気を生成する。本発明の冷蔵庫１０１は、機械室３０１に押し出された、冷凍室の背面側のエバポレータ３０３を、冷却能力を維持するために、縦長にとる。縦長のエバポレータ３０３は、長い冷却領域がとれるので冷却効率が高い。 The evaporator 303 generates cold air that cools the freezing compartment 1205 and the refrigerating compartment 1203. In the refrigerator 101 of the present invention, the evaporator 303 on the back side of the freezer compartment, which is pushed out into the machine compartment 301, is vertically long in order to maintain the cooling capacity. The vertically long evaporator 303 has a long cooling region and thus has high cooling efficiency.

ヒータ３１１は、エバポレータ３０３についた霜をとるためにエバポレータ３０３の下部に設けられる。ヒータ３１１は、一定期間経過すると自動でオンとなり、空気を暖めて、霜を溶かす。溶けた霜は、水となってヒータ３１１下部から排出される。 The heater 311 is provided below the evaporator 303 in order to remove the frost on the evaporator 303. The heater 311 is automatically turned on after a certain period of time to warm the air and melt the frost. The melted frost becomes water and is discharged from the lower portion of the heater 311.

冷凍室背面のエバポレータ３０３の上には、ファン３０５が配置される。ファン３０５は、少なくとも冷凍室１２０５に冷気を流入させる。冷気は、ファン３０５を通った後、マルチダクト３１５を通って、図２の２１１、２１３に対応する吹き出し口３１９、図２の２１５、２１７に対応する吹き出し口３２１の、図２の２１９に対応する吹き出し口３２３から冷凍室１２０５に流れる。 A fan 305 is arranged on the evaporator 303 on the back of the freezer compartment. The fan 305 causes cold air to flow into at least the freezer compartment 1205. After passing through the fan 305, the cool air passes through the multi-duct 315, and corresponds to the outlets 319 corresponding to 211 and 213 in FIG. 2 and the outlets 321 corresponding to 215 and 217 in FIG. From the outlet 323 to the freezer 1205.

冷凍室１２０５を循環した冷気は、図２の２２１に対応する吸入口３２５から吸入され、エバポレータ３０３で再度冷却される。 The cold air that has circulated in the freezer compartment 1205 is sucked through the suction port 325 corresponding to 221 in FIG. 2 and cooled again by the evaporator 303.

また、冷気は、冷蔵室１２０３への流入を切り替えるダンパ３１３を通って、冷蔵室１２０３へ流れる。冷気は、ダンパ３１３を通った後、マルチダクト３１７に入って、図２の吹き出し口２２７、図２の２２９に対応する吹き出し口３２９、図２の２３１に対応する３３１から冷蔵室１２０３に流れる。 Further, the cool air flows into the refrigerating compartment 1203 through the damper 313 that switches the inflow into the refrigerating compartment 1203. After passing through the damper 313, the cold air enters the multi-duct 317, and flows from the outlet 227 of FIG. 2, the outlet 329 corresponding to 229 of FIG. 2, and the outlet 331 of 231 of FIG.

冷蔵室１２０３を循環した冷気は、吸入口２２３、２２５から吸入され、戻りダクトを通って、エバポレータ３０３の下側に戻りエバポレータ３０３で再度冷却される。 The cold air that has circulated in the refrigerating chamber 1203 is sucked through the suction ports 223 and 225, passes through the return duct, returns to the lower side of the evaporator 303, and is cooled again by the evaporator 303.

冷凍室１２０５と冷蔵室１２０３は中仕切り３０７によって区切られている。中仕切り３０７は、冷凍室１２０５の背面側で冷凍室１２０５の内側が上に湾曲して冷凍室１２０５に空間３０９を作る。この空間３０９にファン３０５の少なくとも一部が配置されている。 The freezer compartment 1205 and the refrigerator compartment 1203 are separated by a partition 307. The partition 307 forms a space 309 in the freezing compartment 1205 by bending the inside of the freezing compartment 1205 upward on the back side of the freezing compartment 1205. At least a part of the fan 305 is arranged in this space 309.

本実施の形態のように、中仕切り３０７が冷凍室１２０５の背面側で上に屈曲して空間３０９を作ってもよいが、中仕切り３０７の一部を削って空間３０９を作ってもよい。 As in the present embodiment, the partition 307 may be bent upward on the back side of the freezer compartment 1205 to create the space 309, but a part of the partition 307 may be shaved to create the space 309.

ファン３０５を空間３０９に配置することにより、冷凍室１２０５の背面側の空間を有効利用できる。したがって、冷凍室１２０５の容積を大きく取ることができる。 By disposing the fan 305 in the space 309, the space on the back side of the freezer compartment 1205 can be effectively used. Therefore, the freezer compartment 1205 can have a large volume.

野菜室１２０９は、冷蔵室１２０３の下部であって、中仕切り３０７の直上に設けられている。空間３０９は野菜室１２０９の一部であってもよく、必要とされなくなった野菜室１２０９の一部を冷凍室１２０５の一部にすることができる。また、マルチダクト３１５の一部のデッドスペースを冷凍室１２０５の一部にすることができる。 The vegetable compartment 1209 is provided below the refrigerating compartment 1203 and directly above the partition 307. The space 309 may be a part of the vegetable compartment 1209, and a part of the vegetable compartment 1209 that is no longer needed can be a part of the freezing compartment 1205. Further, a part of the dead space of the multi-duct 315 can be part of the freezer compartment 1205.

このようにすることにより、本発明の冷蔵庫は、ファン３０５が冷凍室１２０５の容積を圧迫せず、冷凍室１２０５の容積を増加することができる。また、本発明は、野菜室１２０９の容積を減らして冷凍室１２０５の容積を増加することができる。さらに、本発明は、マルチダクト３１５の容積を減らして冷凍室１２０５の容積を増加することができる。 By doing so, in the refrigerator of the present invention, the fan 305 does not press the capacity of the freezer compartment 1205, and the capacity of the freezer compartment 1205 can be increased. In addition, the present invention can reduce the volume of the vegetable compartment 1209 and increase the volume of the freezing compartment 1205. Further, the present invention can reduce the volume of the multi-duct 315 and increase the volume of the freezer compartment 1205.

また、本発明の冷蔵庫は、機械室３０１に押し出された、冷凍室背面のエバポレータ３０３の設置場所を上部方向に取ることができる。したがって、エバポレータ３０３を縦長にすることができ、冷却効率を上げ冷凍室背面の容積を増加することができる。 Further, the refrigerator of the present invention can take the installation location of the evaporator 303 pushed out into the machine room 301 on the back side of the freezing room in the upward direction. Therefore, the evaporator 303 can be made vertically long, the cooling efficiency can be increased, and the volume of the back surface of the freezer compartment can be increased.

（ファン遮蔽装置の説明）
図４は、本発明の１つの実施形態におけるファン遮蔽装置の一部であるファン及びファンカバーの概略図である。図５は、本発明の１つの実施形態におけるファン遮蔽装置の正面図である。図４及び５を参照して、ファン及びファンカバーを備えるファン遮蔽装置について説明する。 (Explanation of fan shielding device)
FIG. 4 is a schematic view of a fan and a fan cover that are part of the fan shield device in one embodiment of the present invention. FIG. 5 is a front view of a fan shield device according to one embodiment of the present invention. A fan shield device including a fan and a fan cover will be described with reference to FIGS. 4 and 5.

図４に、ファン４０３とファンカバー４０５を備えるファン遮蔽装置の一部４０１が示される。図４の破線で示されるファン４０３の中心軸と同軸のらせんねじ４０７が付いた、蓋状のファンカバー４０５とファン４０３がファン遮蔽装置に取り付けられる。 FIG. 4 shows a part 401 of the fan shielding device including the fan 403 and the fan cover 405. A fan-shaped fan cover 405 and a fan 403 having a spiral screw 407 coaxial with the central axis of the fan 403 shown by a broken line in FIG. 4 are attached to the fan shielding device.

ファンカバー４０５は、ファン４０３上であってファン４０３の中心軸と同軸上の、らせんねじ４０７と係合する軸部４０９が回転することにより、上下に動作する。ファンカバー４０５は、支持ピン４１１がファンカバー４０５を貫通してガイドすることにより、ファンカバー４０５が平行に動作する。 The fan cover 405 moves up and down by rotating the shaft portion 409 on the fan 403, which is coaxial with the central axis of the fan 403 and which engages with the spiral screw 407. The fan cover 405 operates in parallel by the support pins 411 penetrating and guiding the fan cover 405.

ファンカバー４０５は、上に動作すると開き、エバポレータ３０３で冷却する冷却空間とマルチダクト３１５の空間は、連通し、矢印方向から風がながれる。ファンカバー４０５は、下に動作すると閉じ、エバポレータ３０３で冷却する冷却空間とマルチダクト３１５の空間は遮断される。 When the fan cover 405 is operated upward, the fan cover 405 opens, and the cooling space cooled by the evaporator 303 and the space of the multi-duct 315 communicate with each other, and the air blows from the direction of the arrow. The fan cover 405 closes when it moves downward, and the cooling space cooled by the evaporator 303 and the space of the multi-duct 315 are shut off.

したがって、エバポレータ３０３のヒータ３１１をオンする除霜期間中にファン４０３を遮蔽することができる。除霜期間において、ヒータ３１１が駆動して霜を溶かす。同時に、ファン４０３を遮蔽することで、ファンカバー４０５が閉じて冷却空間とマルチダクト３１５の空間とを遮断し、庫内に暖気が回らず温度を上げることがない。よって、本発明は、省電力を達成する。 Therefore, the fan 403 can be shielded during the defrosting period when the heater 311 of the evaporator 303 is turned on. During the defrosting period, the heater 311 is driven to melt the frost. At the same time, by shielding the fan 403, the fan cover 405 is closed and the cooling space and the space of the multi-duct 315 are cut off, so that warm air does not rotate in the refrigerator and the temperature does not rise. Therefore, the present invention achieves power saving.

図５は、ファン遮蔽装置５０１の正面図を示す。ファン遮蔽装置５０１は、図３の３０５に対応するファン４０３とファンカバー４０５と、図３のマルチダクト３１５、図２の２１１、２１３に対応し、図３の３１９に対応する吹き出し口５０５、５０７、図２の２１５、２１７に対応し、図３の３２１に対応する吹き出し口５０９、５１１、図２の２１９に対応に対応し、図３の３２３に対応する吹き出し口５１３、図２の２２１に対応し、図３の３２５に対応する吸入口５１５を含めた構成部品からなる。 FIG. 5 shows a front view of the fan shielding device 501. The fan shielding device 501 corresponds to the fan 403 and the fan cover 405 corresponding to 305 of FIG. 3, the multi-duct 315 of FIG. 3, 211 and 213 of FIG. 2, and the outlets 505 and 507 corresponding to 319 of FIG. 2, corresponding to 215 and 217 of FIG. 2 and corresponding to outlets 509 and 511 corresponding to 321 of FIG. 3, corresponding to 219 of FIG. 2 and corresponding to outlet 513 corresponding to 323 of FIG. 3 and 221 of FIG. Correspondingly, it is composed of components including an inlet 515 corresponding to 325 in FIG.

図３の空間３０９には、ファン遮蔽装置５０１の線Ｂ−Ｂより上の部分が配置される。また、ファン遮蔽装置の一部４０１は、ファン遮蔽装置５０１の位置５０３の裏面に配置される。このようにファン４０３及びファンカバー４０５を含むファン遮蔽装置５０１の一部が、空間３０９に配置されている。 The space above the line BB of the fan shielding device 501 is arranged in the space 309 of FIG. Further, a part 401 of the fan shielding device is arranged on the back surface of the position 503 of the fan shielding device 501. As described above, a part of the fan shielding device 501 including the fan 403 and the fan cover 405 is arranged in the space 309.

ここで、重要なことは、ファン４０３が設置される位置５０３と平行に吹き出し口５０５及び５０７が配置されていることである。冷気は、冷凍室１２０５の天井付近から送る必要がある。従来は、ファンの位置の上に吹き出し口があった。 Here, what is important is that the air outlets 505 and 507 are arranged in parallel with the position 503 where the fan 403 is installed. Cold air needs to be sent from around the ceiling of the freezer compartment 1205. In the past, there was an outlet above the position of the fan.

しかしながら、本発明では、ファン４０３が冷凍室１２０５の上部に配置することができるため、送風のための吹き出し口５０５は、ファン４０３設置される位置５０３と平行に置くことができる。このようにすることで、冷気を強い風量で冷凍室１２０５に送ることができるため、省電力にできる。 However, in the present invention, since the fan 403 can be arranged above the freezer compartment 1205, the air outlet 505 for blowing air can be placed parallel to the position 503 where the fan 403 is installed. By doing so, cold air can be sent to the freezer compartment 1205 with a strong air flow, so that power can be saved.

本発明により、ファン遮蔽装置が設けられる冷蔵庫において、冷凍室１２０５の容積を増加することができる。また、本発明は、ファン遮蔽装置を設けることで省電力な冷蔵庫を提供することができる。さらに、本発明は、縦長のエバポレータ３０３を冷凍室背面に配置することにより冷却効率がよく、冷凍室１２０５の容積を増加した冷蔵庫を提供することができる。 According to the present invention, it is possible to increase the volume of the freezer compartment 1205 in the refrigerator provided with the fan shield device. In addition, the present invention can provide a power-saving refrigerator by providing a fan shield device. Further, the present invention can provide a refrigerator in which the longitudinally long evaporator 303 is arranged on the back surface of the freezing compartment to improve the cooling efficiency and increase the volume of the freezing compartment 1205.

本発明は、ファンが冷凍室背面に設置された冷蔵庫に適用できる。また、本発明は、省電力のためのファン遮蔽装置が設置された冷蔵庫に適用できる。 The present invention can be applied to a refrigerator in which a fan is installed on the back of a freezer. Further, the present invention can be applied to a refrigerator in which a fan shielding device for power saving is installed.
