Abstract

<P>PROBLEM TO BE SOLVED: To prevent lead wires of electrical parts from being brought into contact with cooling fins of a cooler in a cooling device disposed at a refrigerator or a freezer. <P>SOLUTION: A guide member 20 is provided so as to pass an upper part of the cooling fin 12 of the cooler 11, and the lead wires 14a, 15a, 16a of a heater for defrosting 14, a thermostat 15, and a temperature fuse 16 are attached onto the guide member 20. The lead wires can be retained so as not to break off easily by simple work that the lead wires are inserted in a rising part 21 formed at a flat surface part 20b of the guide member 20 and then the rising part 21 is slightly pressed down. The contact between the lead wires of the electrical parts and the cooling fin 12 can be completely prevented, therefore possibility of accidents, such as electricity leakage, short, or open circuit due to breakage in shields of the lead wires can be eliminated. Dissolution water is not attached onto the lead wires at the time of defrosting, thus preventing the inside of the refrigerator or the freezer from getting wet with water. <P>COPYRIGHT: (C)2004,JPO

Description

【0001】
【発明の属する技術分野】
本発明は、冷蔵庫や冷凍庫に設置される冷却装置に関し、詳しくは、サーモスタット,ヒューズ,ヒータ等の電気部品のリード線を、冷却器の冷却フィンに接触させないようにするための技術に関する。
【0002】
【従来の技術】
図4は、冷蔵庫や冷凍庫に設置される冷却装置1の一例を示すものである。この冷却装置1は、多数の冷却フィン3を有する冷却器2と、冷気循環用ファン6とを備え、それぞれベース部材7に取り付けられている。冷却器2の表面には、除霜用のヒータ4,サーモスタット5、温度ヒューズ(図示せず)等の電気部品が設けられる。そして、それらのリード線4a,5aは、冷却器2の周辺すなわち冷気の循環空間において、冷却フィン3や、除霜用ヒータ4,冷気循環用ファン6と接触することがないよう結束バンド8により束ねられ、冷媒循環用のパイプ9などに沿って外部と配線接続されている。
【0003】
特許文献1には、冷蔵庫の冷却器において、リード線(電装コード)を冷却器(蒸発器)のフィンに接触させないようにするため、冷却器の支持装置に突起部を設け、この突起部にリード線を係止させて保持する構造が記載されている。
【0004】
【特許文献1】
特公平7−104097号公報
【0005】
【発明が解決しようとする課題】
図4に示す前記従来の冷却装置1にあっては、除霜用ヒータ4やサーモスタット5等の電気部品4,5の取付位置や結束バンド8の配置を、いつでも自由に設定できるわけではない。このためリード線4a,5aを、冷却フィン3・除霜用ヒータ4・冷気循環用ファン6などと接触させないように配置するのが困難な場合がある。特に、図示する従来例では、除霜用ヒータ4及びサーモスタット5を冷却器2の冷却フィン3表面に取り付けているため、それらのリード線4a,5aが冷却フィン3の端縁部と接触せざるを得なくなっている。それ故、冷却装置1の運転時に生じる振動により、リード線4a,5aが冷却フィン3に絶え間なく衝突し、その結果、リード線4a,5aの被覆が破れて短絡事故、漏電事故、断線事故等を起こすおそれがあった。また、リード線4a,5aが冷却フィンに接触しているため、除霜時に溶け出た水がリード線4a,5aを伝って、冷蔵庫内(冷凍庫)に流れ込んだり滴下したりする場合があった。
【0006】
他方、特許文献1に記載の技術は、冷却器を立面部に設置する場合に適用されるものであり、図4に示すような水平面状の箇所へ設置するものに対して応用するのは難しい。
【0007】
【課題を解決するための手段】
本発明が前記従来の課題を解決するために採用した冷却装置の特徴とするところは、複数枚の冷却フィンを有する冷却器と、サーモスタット,ヒューズ,ヒータ等の電気部品とを備えるものにおいて、前記冷却器における冷却フィンの上方部にガイド部材を配設し、前記電気部品のリード線を、前記ガイド部材の上表面に取り付けたことである。
【0008】
かかる構成により、ガイド部材の上表面に取り付けたリード線は、冷却フィンとの接触が阻止されるから、リード線が損傷を受けて様々な事故を引き起こすのを、確実に防止することができる。
【0009】
【発明の実施の形態】
[第1の実施形態]
図1乃至図3は本発明に係る冷却装置10の一実施形態を示すものであって、図1は主要部の構成を分解して示す斜視図、図2は同冷却装置10の主要部を示す斜視図、図3は同冷却装置10の全体を示す斜視図である。図1に示す如く、本例の冷却装置10は、複数枚の冷却フィン12を冷媒循環パイプ13でほぼ等間隔に連結して成る冷却器11、該冷却器11の表面に付着する霜を除去するための除霜用ヒータ14、冷却器11の温度変化に合わせてヒータ14への通電を制御するサーモスタット15、冷却器11が異常温度になったときに通電を切断するための温度ヒューズ16、冷気循環用のファン18等を備えて成る。これら除霜用ヒータ14・サーモスタット15・温度ヒューズ16は、図2のように冷却器11表面に装着される。前記冷却器11及びファン18は、ベース部材17に取り付けられる。なおベース部材17は、除霜時に生成される融解水を排出するための排水部17a及び排水傾斜部17bを備えている。そして図3に示す如く、上述の主要部と、コンプレッサ32,凝縮器ファン33,凝縮器34等とを支持盤35上で組み付け付けることにより、冷却装置10が構成されている。
【0010】
本発明は、冷却器11の冷却フィン12の上方部を跨ぐようにガイド部材20を設け、このガイド部材20に、除霜用ヒータ14・サーモスタット15・温度ヒューズ16等の電気部品のリード線14a,15a,16aを取り付けるようにしたところを特色としている。本例では、ガイド部材20をほぼコ字型に形成し、両端のフランジ状部分20aで冷却フィン12の両外側面を挟むように構成した。なおガイド部材20の両端部に、冷却器11の冷媒循環パイプ13と同ピッチで、パイプ外径よりもわずかに大きいU字形の切欠22を形成し、このU字形切欠22に冷媒循環パイプ13を挿入させるようにして、ガイド部材20を取り付けてもよい。かかる構成により、ガイド部材20を冷却器11に組み付けるのが容易になる。
【0011】
ガイド部材20の平面部20bには、適所に切り起こし部21が形成される。この切り起こし部21内にリード線を挿入したのち、切り起こし部21をわずかに押し下げることにより、リード線が容易には脱落することがないよう保持することができる。すなわち、リード線の取付作業を非常に簡単に行える。
【0012】
前記の如く構成した本例の冷却装置10は、ガイド部材20によって、冷却器11に装着した除霜用ヒータ14・サーモスタット15・温度ヒューズ16等のリード線14a,15a,16aが、冷却フィン12と接触するのを確実に阻止できる。従って、装置10が振動しても、リード線14a,15a,16aが冷却フィン12に衝突することがないから、従来のようにリード線の被覆が破損して漏電・短絡・通電切断等の事故を招くおそれがない。また、ガイド部材20は冷却器11にの上方部に装着するから、リード線14a,15a,16aと除霜用ヒータ14との接触が回避され、安全性が向上する。さらに、除霜時に溶融水がリード線14a,15a,16aに付着することもなくなるから、冷蔵庫や冷凍庫内を水で濡らすおそれもなくなる。
【0013】
ところで図3の図(A)に示すように、支持盤35上に組み付けた冷却器11の上方を、発泡スチロール等の断熱材30で覆う構成とする場合、同図(B)に示す如く、断熱材30の下面には、ガイド部材20の上面に設けた切り起こし部21及びリード線14a,15a,16aを収納するための凹溝31を形成することが望ましい。なお、この凹溝31の開口部は、ガイド部材20の平面部21で閉塞されるから、冷気を循環させる際に乱流を発生させることがなく、円滑な冷気の流れを形成するのに、障害とならない。
【0014】
【発明の効果】
本発明に係る冷却装置は、ガイド部材によって、電気部品のリード線が冷却フィン及びヒータと接触するのを確実に阻止するから、リード線が破損して各種事故を招くのを防止する。また、除霜時に溶融水がリード線に付着するのを阻止するから、水で冷蔵庫又は冷凍庫内が濡れるのを防止できる。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a cooling device installed in a refrigerator or a freezer, and more particularly, to a technique for preventing a lead wire of an electric component such as a thermostat, a fuse, or a heater from contacting a cooling fin of a cooler.
[0002]
[Prior art]
FIG. 4 shows an example of the cooling device 1 installed in a refrigerator or a freezer. The cooling device 1 includes a cooler 2 having a large number of cooling fins 3 and a cool air circulation fan 6, each of which is attached to a base member 7. On the surface of the cooler 2, electric components such as a heater 4 for defrosting, a thermostat 5, and a temperature fuse (not shown) are provided.

[0004]
[Patent Document 1]
Japanese Patent Publication No. 7-104097
[Problems to be solved by the invention]
In the conventional cooling device 1 shown in FIG. 4, the mounting positions of the electric components 4 and 5, such as the defrost heater 4 and the thermostat 5, and the arrangement of the binding band 8 cannot always be freely set. For this reason, it may be difficult to arrange the lead wires 4a and 5a so as not to come into contact with the cooling fins 3, the defrosting heater 4, the cool air circulation fan 6, and the like. In particular, in the illustrated conventional example, since the defrosting heater 4 and the thermostat 5 are attached to the surface of the cooling fin 3 of the cooler 2, their lead wires 4a and 5a do not come into contact with the edge of the cooling fin 3. Is no longer gaining. Therefore, the lead wires 4a, 5a constantly collide with the cooling fins 3 due to the vibration generated during the operation of the cooling device 1, and as a result, the coating of the lead wires 4a, 5a is broken, resulting in a short circuit accident, a short circuit accident, a disconnection accident, etc. Could occur. Further, since the lead wires 4a and 5a are in contact with the cooling fins, water melted during defrosting may flow along the lead wires 4a and 5a and flow into the refrigerator (freezer) or drop. .
[0006]
On the other hand, the technology described in Patent Literature 1 is applied to a case where a cooler is installed on an upright portion, and is applied to a case where the cooler is installed on a horizontal surface as shown in FIG. difficult.
[0007]

A guide member is provided above the cooling fins in the cooler, and a lead wire of the electric component is attached to an upper surface of the guide member.
[0008]
With this configuration, the lead wire attached to the upper surface of the guide member is prevented from contacting the cooling fins, so that it is possible to reliably prevent the lead wire from being damaged and causing various accidents.
[0009]
BEST MODE FOR CARRYING OUT THE INVENTION
[First Embodiment]
1 to 3 show an embodiment of a cooling device 10 according to the present invention. FIG. 1 is an exploded perspective view showing a configuration of a main part, and FIG. FIG. 3 is a perspective view showing the entire cooling device 10. As shown in FIG. 1, a cooling device 10 of the present embodiment includes a cooler 11 in which a plurality of cooling fins 12 are connected at substantially equal intervals by a refrigerant circulation pipe 13, and removes frost adhering to the surface of the cooler 11. A defrosting heater 14, a thermostat 15 for controlling energization to the heater 14 in accordance with a temperature change of the cooler 11, a temperature fuse 16 for cutting off energization when the cooler 11 becomes abnormal temperature, A cooling air circulation fan 18 and the like are provided. These defrost heater 14, thermostat 15, and thermal fuse 16 are mounted on the surface of the cooler 11 as shown in FIG. The cooler 11 and the fan 18 are attached to the base member 17. In addition, the base member 17 is provided with a drainage portion 17a and a drainage inclined portion 17b for discharging the molten water generated at the time of defrosting. Then, as shown in FIG. 3, the cooling device 10 is configured by assembling the above-described main parts, the compressor 32, the condenser fan 33, the condenser 34, and the like on the support board 35.
[0010]
According to the present invention, a guide member 20 is provided so as to straddle the upper part of the cooling fin 12 of the cooler 11, and the guide member 20 is provided with a lead wire 14a of an electric component such as a heater 14 for defrosting, a thermostat 15 and a temperature fuse 16. , 15a, and 16a are featured. In the present embodiment, the guide member 20 is formed in a substantially U-shape, and the outer peripheral surfaces of the cooling fins 12 are sandwiched between the flange-like portions 20a at both ends. In addition, a U-shaped notch 22 slightly larger than the pipe outer diameter is formed at both ends of the guide member 20 at the same pitch as the refrigerant circulation pipe 13 of the cooler 11, and the refrigerant circulation pipe 13 is formed in the U-shaped notch 22. The guide member 20 may be attached so as to be inserted. With this configuration, it is easy to assemble the guide member 20 to the cooler 11.
[0011]
A cut-and-raised portion 21 is formed at an appropriate position on the flat portion 20b of the guide member 20. After the lead wire is inserted into the cut-and-raised portion 21, by slightly pushing down the cut-and-raised portion 21, the lead wire can be held so as not to fall off easily. That is, the work of attaching the lead wire can be performed very easily.
[0012]
In the cooling device 10 of this embodiment configured as described above, the lead wires 14 a, 15 a, 16 a such as the defrosting heater 14, the thermostat 15, and the temperature fuse 16 mounted on the cooler 11 are connected to the cooling fins 12 by the guide member 20. Can be reliably prevented from coming into contact with. Therefore, even if the device 10 vibrates, the lead wires 14a, 15a, and 16a do not collide with the cooling fins 12, so that the covering of the lead wire is damaged as in the conventional case, resulting in an accident such as a short circuit, short circuit, or disconnection of current. There is no possibility of inviting. Further, since the guide member 20 is mounted on the upper part of the cooler 11, contact between the lead wires 14a, 15a, 16a and the defrost heater 14 is avoided, and safety is improved. Further, since the molten water does not adhere to the lead wires 14a, 15a, 16a during defrosting, there is no danger of wetting the inside of the refrigerator or freezer with water.
[0013]
By the way, as shown in FIG. 3A, when the upper part of the cooler 11 assembled on the support board 35 is covered with a heat insulating material 30 such as styrene foam, as shown in FIG. It is desirable to form a cut-and-raised portion 21 provided on the upper surface of the guide member 20 and a concave groove 31 for accommodating the lead wires 14a, 15a, 16a on the lower surface of the material 30. Since the opening of the concave groove 31 is closed by the flat portion 21 of the guide member 20, no turbulence is generated when circulating the cool air, so that a smooth flow of the cool air is formed. Does not hinder.
[0014]
【The invention's effect】
In the cooling device according to the present invention, the guide member reliably prevents the lead wire of the electric component from contacting the cooling fin and the heater, thereby preventing the lead wire from being damaged and causing various accidents. Further, since the molten water is prevented from adhering to the lead wire during defrosting, it is possible to prevent the inside of the refrigerator or the freezer from getting wet with water.
