Description

【0001】
【発明の属する技術分野】
本発明は、放熱パイプを利用して開口周辺の結露を防止する冷蔵庫に関する。
【0002】
【従来の技術】
冷蔵庫に関する従来技術としては、特開2001−12841号公報に記載されたものがある。
【0003】
この公報に記載のものは、放熱パイプを冷蔵庫の開口に配置して加熱し、この加熱により結露を防止したものである。
【0004】
また、この公報に記載されたものと同種のものについて、図2に沿って説明する。
【0005】
31は扉を外した状態を示す冷凍冷蔵庫で、断熱箱体32を仕切り33、34、35、36で仕切って、冷蔵室R、野菜室V、製氷室I、温度切替室S、冷凍室Fを構成している。凝縮器は第1の放熱パイプ37と第2の放熱パイプとで構成されており、第1の放熱パイプを扉との当接面内側に一筆書きになるように配置していた。また、第2の放熱パイプ37を、両側板、天板の内側に配置していた(図示せず)。
【0006】
【発明が解決しようとする課題】
前述のように図2に示す冷蔵庫では、その第1の放熱パイプ37を一筆書きになるように配置していたので、冷蔵室Rと野菜室Vとを仕切る仕切り33に、第1の放熱パイプ37が往復し、実質的に2本の放熱パイプが設置されている状態と同じ状態になっていた。
【0007】
この冷蔵室Rと野菜室Vとを仕切る仕切り33は、それほど冷却されない室の仕切りのためそれほど温める必要はなく、この第1の放熱パイプ37からの熱が野菜室Vや、冷蔵室Rに伝わり、冷蔵庫の効率を下げる要因になっていた。しかし、全く放熱パイプを配置しないと、今度は結露する恐れが生ずる。
【0008】
この発明は、放熱パイプから庫内への熱の流入を抑えた冷蔵庫を提供するものである。
【0009】
【課題を解決するための手段】
本発明は、断熱箱体を仕切って冷蔵室と野菜室とを形成し、これらの各室の開口を扉で開閉自在に塞ぐ冷蔵庫において、前記冷蔵室と前記野菜室との仕切り及び前記開口の周囲に配設される第1の放熱パイプ部と、側板の内側に配設される第2の放熱パイプ部と、前記第2の放熱パイプ部から前記第1の放熱パイプ部の順で冷媒を流す圧縮機とを備えることを特徴とする。
【0010】
また、前記冷蔵室と前記野菜室とを仕切る仕切りには、前記第1の放熱パイプ部を1本のみを取付けたものである。
【0011】
【発明の実施の形態】
本発明の実施の形態を図面に基づき説明する。
【0012】
図1は本発明の冷蔵庫における放熱パイプの配置状態を示す説明図である。
【0013】
この図1に示す1は断熱箱体で、側板2、天板(側板)3、底板(側板)4とで構成されている。
【0014】
Rは約3℃に制御される冷蔵室、Vは約5℃に制御される野菜室、Iは約−18℃に制御される製氷室、Sは設定温度を3℃〜−18℃に設定できる温度切替室、Fは約−18℃に制御される冷凍室である。
【0015】
5は冷蔵室Rと野菜室Vとを仕切る仕切り、6は野菜室Vと製氷室I及び切替室Sとを仕切る仕切り、7は製氷室Iと切替室Sとを仕切る仕切り、8は製氷室I及び切替室Sと冷凍室Fとを仕切る仕切りである。
【0016】
図示しないが、この冷蔵庫には、圧縮機、凝縮器、減圧装置、蒸発器を順次冷媒管で接続した冷媒回路を備えており、特に凝縮器は第1の放熱パイプ9と第2の放熱パイプ10とで構成すると共に、例えば、第2の放熱パイプ10から第1の放熱パイプ9の順で圧縮機からの冷媒が流れるように構成されている。
【0017】
前記第2の放熱パイプ10は、側板2及び天板3の内側に配置されていると共に、冷蔵室Rを構成する側板2A及び天板3の扉への当接面の近辺に位置するように、その一部の経路を近づけて配置している。すなわち第2の放熱パイプ10A、10Bは冷蔵室Rに近接させて配置している。
【0018】
また、第1の放熱パイプ9は、底板4、仕切り5、6、7、8の扉に接する当接面の内側に配置されている。この第1の放熱パイプ9は、図に示すように一筆書きのように配置されているので、底板9や、仕切り6、7、8には、放熱パイプ9が往復し、実質的に2本のパイプが配置されていることと同じ状態になっている。
【0019】
尚、各室R、V、I、S、Fの開口を開閉自在塞ぐ扉を備えているが、図示しない。
【0020】
このように構成された冷蔵庫では、放熱パイプを第1の放熱パイプ9と第2の放熱パイプ10とで構成している。
【0021】
そして、野菜室V、製氷室I、温度切替室S、冷凍室Fの開口周辺や仕切り5、6、7、8の前記扉に接する当接面の内側には第1の放熱パイプ9を配置する。また、冷蔵室Rの横の側板部分2Aや天板(側板)3には、その内側であり、且つ、扉に接する当接面に近接した位置に第2の放熱パイプ10A、10Bを配置している。
【0022】
このため、野菜室V、製氷室I、温度切替室S、冷凍室Fの開口周辺や仕切り6、7、8で扉に当接する結露しやすい当接面には、第1の放熱パイプ9の熱が伝わりやすくして結露を防止できる。また、冷蔵室Rと野菜室Vの仕切りや冷蔵室Rの横の側板部分2Aや天板3の扉への当接面のように結露しにくい部分には、第2の放熱パイプ10A、10B及び一本の第1の放熱パイプを配置して加熱しにくくしたので、これらの放熱パイプから冷蔵室Rに流入する熱を抑えることができると共に、結露も防止することができる。
【0023】
冷蔵室Rと野菜室Vとを仕切る仕切り5には、その扉に接する当接面の内側には、第1の放熱パイプ9を1本のみ取付けたもので、比較的結露しにくいこの仕切り5の加熱量を少なくして、この仕切り5から冷蔵室Rや野菜室Vに流入する熱を抑えることができると共に、結露も防止することができる。
【0024】
この実施例では、第2の放熱パイプから第1の放熱パイプへと圧縮機からの冷媒を流した例で説明したが、このようにすれば、圧縮機からながれでた温度の高い冷媒が冷蔵庫の側板内の第2の放熱パイプ10で冷却されてから、第1の放熱パイプに流れるので、この第1放熱パイプから冷蔵室R、野菜室V、製氷室I、温度切替室S、冷凍室Fに流入する熱を抑えることができる。
【0025】
【発明の効果】
以上説明したように、本発明によれば、冷蔵庫において、放熱パイプを開口周辺に配置された第1の放熱パイプ部と、側板内に配置された第2の放熱パイプ部とで構成し、前記第2の放熱パイプ部から前記第1の放熱パイプ部の順で冷媒を流す圧縮機とを備えているので、圧縮機から流れ出た温度の高い冷媒が冷蔵庫の側板内の第2の放熱パイプ部で冷却されてから、第1の放熱パイプ部に流れるので、この第1放熱パイプから各室R、V、I、S、Fに流入する熱を抑えることができる。

The condenser is composed of a first heat radiating pipe 37 and a second heat radiating pipe, and the first heat radiating pipe is arranged inside the contact surface with the door so as to be drawn in one stroke. Further, the second heat radiating pipes 37 are arranged inside the both side plates and the top plate (not shown).
[0006]
[Problems to be solved by the invention]
As described above, in the refrigerator shown in FIG. 2, the first radiating pipe 37 is arranged so as to draw a single stroke, so that the first radiating pipe 37 is provided in the partition 33 that separates the refrigerator compartment R from the vegetable compartment V. 37 reciprocated, and the state was substantially the same as the state in which two heat radiation pipes were installed.
[0007]
The partition 33 that separates the refrigerator compartment R from the vegetable compartment V does not need to be heated so much because it is a partition that is not so cooled, and the heat from the first radiating pipe 37 is transmitted to the vegetable compartment V and the refrigerator compartment R. , Which was a factor in lowering the efficiency of the refrigerator. However, if no heat dissipating pipe is arranged, there is a risk of dew formation.
[0008]
The present invention provides a refrigerator in which the flow of heat from the heat radiating pipe into the refrigerator is suppressed.
[0009]
[Means for Solving the Problems]
The present invention provides a refrigerator in which a heat insulation box is partitioned to form a refrigerator compartment and a vegetable compartment, and the opening of each of these compartments is openably closed by a door.

Further, the partition for separating the refrigerator compartment and the vegetable compartment is provided with only one first radiating pipe portion.
[0011]
BEST MODE FOR CARRYING OUT THE INVENTION
An embodiment of the present invention will be described with reference to the drawings.
[0012]
FIG. 1 is an explanatory view showing an arrangement state of a heat radiation pipe in a refrigerator of the present invention.
[0013]
In FIG. 1, reference numeral 1 denotes a heat insulating box, which includes a side plate 2, a top plate (side plate) 3, and a bottom plate (side plate) 4.
[0014]
R is a refrigerator room controlled at about 3 ° C., V is a vegetable room controlled at about 5 ° C., I is an ice making room controlled at about −18 ° C., S is a set temperature of 3 ° C. to −18 ° C. A possible temperature switching room, F is a freezing room controlled at about −18 ° C.
[0015]
5 is a partition for partitioning the refrigerator compartment R and the vegetable compartment V, 6 is a partition for partitioning the vegetable compartment V, the ice making compartment I and the switching compartment S, 7 is a partition for dividing the ice making compartment I and the switching compartment S, and 8 is an ice making compartment. This is a partition that separates the I and switching room S from the freezing room F.
[0016]
Although not shown, the refrigerator is provided with a refrigerant circuit in which a compressor, a condenser, a decompression device, and an evaporator are sequentially connected by a refrigerant pipe. In particular, the condenser includes a first radiation pipe 9 and a second radiation pipe. 10 and, for example, the refrigerant from the compressor flows in the order from the second heat radiation pipe 10 to the first heat radiation pipe 9.
[0017]
The second heat radiating pipe 10 is disposed inside the side plate 2 and the top plate 3, and is located near a contact surface of the side plate 2 A and the top plate 3 constituting the refrigerator compartment R with the door. , Some of the routes are arranged close to each other. That is, the second heat radiation pipes 10A and 10B are arranged close to the refrigerator compartment R.
[0018]
Further, the first heat radiation pipe 9 is disposed inside a contact surface of the bottom plate 4 and the partitions 5, 6, 7, 8 which are in contact with the doors. Since the first heat radiating pipe 9 is arranged in a single stroke as shown in the figure, the heat radiating pipe 9 reciprocates on the bottom plate 9 and the partitions 6, 7, and 8, and substantially two pipes are formed. It is in the same state that the pipe is arranged.
[0019]
Although doors are provided to open and close the openings of the chambers R, V, I, S, and F, they are not shown.
[0020]
In the refrigerator configured as described above, the heat radiating pipe is constituted by the first heat radiating pipe 9 and the second heat radiating pipe 10.
[0021]
Then, the first heat radiating pipe 9 is disposed around the openings of the vegetable room V, the ice making room I, the temperature switching room S, and the freezing room F, and inside the abutment surfaces of the partitions 5, 6, 7, and 8 which are in contact with the doors. I do. Further, the second heat radiation pipes 10A and 10B are arranged inside the side plate portion 2A and the top plate (side plate) 3 of the refrigerator compartment R at a position close to the contact surface which is in contact with the door. ing.
[0022]
For this reason, the first radiating pipe 9 is provided on the vegetable room V, the ice making room I, the temperature switching room S, and around the openings of the freezing room F and on the contact surfaces where the dew condensation comes into contact with the doors at the partitions 6, 7, 8. Heat can be easily transmitted to prevent condensation. The second heat radiation pipes 10A and 10B are provided in the partition between the refrigerator compartment R and the vegetable compartment V and in the portion where the dew condensation is difficult such as the side plate portion 2A of the refrigerator compartment R and the contact surface of the top plate 3 with the door. Further, since one first heat radiation pipe is arranged to make it difficult to heat, heat flowing from these heat radiation pipes into the refrigerator compartment R can be suppressed, and dew condensation can be prevented.
[0023]
The partition 5 for partitioning the refrigerator compartment R and the vegetable compartment V has only one first heat radiating pipe 9 attached to the inside of the abutting surface in contact with the door, and is relatively resistant to condensation. By reducing the amount of heating, heat flowing from the partition 5 into the refrigerator compartment R or the vegetable compartment V can be suppressed, and dew condensation can be prevented.
[0024]
In this embodiment, an example has been described in which the refrigerant from the compressor flows from the second radiating pipe to the first radiating pipe, but in this case, the high-temperature refrigerant flowing from the compressor is supplied to the refrigerator. After being cooled by the second heat radiating pipe 10 in the side plate of the above, it flows to the first heat radiating pipe, and from this first heat radiating pipe, the refrigerator room R, the vegetable room V, the ice making room I, the temperature switching room S, the freezing room The heat flowing into F can be suppressed.
[0025]
【The invention's effect】
As described above, according to the present invention, in the refrigerator, the heat radiating pipe is constituted by the first heat radiating pipe portion arranged around the opening and the second heat radiating pipe portion arranged in the side plate, A compressor for flowing a refrigerant in order from the second heat radiation pipe portion to the first heat radiation pipe portion, so that the high-temperature refrigerant flowing out of the compressor flows into the second heat radiation pipe portion in the side plate of the refrigerator. After the cooling, the heat flows into the first heat radiating pipe, so that the heat flowing from the first heat radiating pipe into each of the chambers R, V, I, S, and F can be suppressed.
