For example, the electrical wiring 2 connects electrical components such as a fan motor, a door switch, and a temperature sensor (not shown) and a control circuit (not shown).

この電気配線２は、直流電流が流れるＤＣ線２１と、交流電流が流れるＡＣ線２２とを有する。上記ＤＣ線２１および上記ＡＣ線２２は、それぞれ、導体とこの導体を被覆する絶縁体とを有する。上記ＤＣ線２１および上記ＡＣ線２２は、上記空間１３から、上記外箱１１の外側や上記内箱１２の内側に、引き出されている。   The electrical wiring 2 has a DC line 21 through which a direct current flows and an AC line 22 through which an alternating current flows. Each of the DC line 21 and the AC line 22 includes a conductor and an insulator covering the conductor. The DC line 21 and the AC line 22 are drawn from the space 13 to the outside of the outer box 11 and the inside of the inner box 12.

上記ＤＣ線２１と上記ＡＣ線２２は、互いに分離して接触しないように、配列されている。そして、このように配列されている上記ＤＣ線２１および上記ＡＣ線２２によって、電気配線の配列構造を構成している。   The DC line 21 and the AC line 22 are arranged so as not to be in contact with each other. The DC lines 21 and the AC lines 22 arranged in this way constitute an electric wiring arrangement structure.

具体的に述べると、上記外箱１１は、互いに分離されたＤＣ線専用孔部１１ａおよびＡＣ線専用孔部１１ｂを有し、上記ＤＣ線２１は、上記ＤＣ線専用孔部１１ａから、上記外箱１１の外側に引き出される一方、上記ＡＣ線２２は、上記ＡＣ線専用孔部１１ｂから、上記外箱１１の外側に引き出される。   More specifically, the outer box 11 has a DC wire dedicated hole portion 11a and an AC wire dedicated hole portion 11b separated from each other, and the DC wire 21 is connected to the outer periphery of the DC wire dedicated hole portion 11a. On the other hand, the AC line 22 is pulled out to the outside of the outer box 11 from the AC line dedicated hole 11b.

また、上記内箱１２は、互いに分離されたＤＣ線専用孔部１２ａおよびＡＣ線専用孔部１２ｂを有し、上記ＤＣ線２１は、上記ＤＣ線専用孔部１２ａから、上記内箱１２の内側に引き出される一方、上記ＡＣ線２２は、上記ＡＣ線専用孔部１２ｂから、上記内箱１２の内側に引き出される。   The inner box 12 has a DC line dedicated hole 12a and an AC line dedicated hole 12b separated from each other, and the DC line 21 is connected to the inner side of the inner box 12 from the DC line dedicated hole 12a. On the other hand, the AC wire 22 is drawn inside the inner box 12 from the AC wire dedicated hole 12b.

上記ＤＣ線２１の端末には、ＤＣコネクタ２３が取り付けられている。つまり、上記ＤＣコネクタ２３は、上記外箱１１の外側および上記内箱１２の内側のそれぞれに、配置されている。   A DC connector 23 is attached to the terminal of the DC line 21. That is, the DC connector 23 is disposed on the outer side of the outer box 11 and the inner side of the inner box 12.

上記ＡＣ線２２の端末には、ＡＣコネクタ２４が取り付けられている。つまり、上記ＡＣコネクタ２４は、上記外箱１１の外側および上記内箱１２の内側のそれぞれに、配置されている。   An AC connector 24 is attached to the terminal of the AC line 22. That is, the AC connector 24 is disposed on the outer side of the outer box 11 and the inner side of the inner box 12.

上記空間１３では、上記ＤＣ線２１と上記ＡＣ線２２は、互いに交わらないように分離して配置されている。上記ＤＣ線２１は、概ね、上記冷蔵庫本体１の左右一方側に配置され、上記ＡＣ線２２は、概ね、上記冷蔵庫本体１の左右他方側に配置されている。   In the space 13, the DC line 21 and the AC line 22 are arranged separately so as not to cross each other. The DC line 21 is generally disposed on the left and right sides of the refrigerator body 1, and the AC line 22 is generally disposed on the left and right sides of the refrigerator body 1.

具体的に述べると、上記ＤＣ線２１は、上記冷蔵庫本体１の上下方向に延びている主要部２１ａと、この主要部２１ａから左右方向や前後方向に延びている枝部２１ｂとを有する。上記ＡＣ線２２は、上記冷蔵庫本体１の上下方向に延びている主要部２２ａと、この主要部２２ａから左右方向や前後方向に延びている枝部２２ｂとを有する。そして、上記ＤＣ線２１の主要部２１ａは、上記冷蔵庫本体１の左右一方側に配置される一方、上記ＡＣ線２２の主要部２２ａは、上記冷蔵庫本体１の左右他方側に配置されている。   More specifically, the DC wire 21 has a main portion 21a extending in the vertical direction of the refrigerator body 1 and a branch portion 21b extending from the main portion 21a in the left-right direction and the front-rear direction. The AC line 22 has a main portion 22a extending in the up-down direction of the refrigerator body 1 and a branch portion 22b extending from the main portion 22a in the left-right direction and the front-rear direction. And the main part 21a of the said DC wire 21 is arrange | positioned at the left-right one side of the said refrigerator main body 1, On the other hand, the main part 22a of the said AC wire 22 is arrange | positioned at the right-and-left other side of the said refrigerator main body 1.

上記空間１３にある上記ＡＣ線２２には、耐圧用の絶縁チューブ２５が被覆されている。上記電気配線２が、高圧電源に接続される場合に、上記絶縁チューブ２５が、上記ＡＣ線２２に対して耐圧の対応となる。つまり、この冷蔵庫を、定格電圧が２００Ｖ等の高圧電源地域へ輸出して、この高圧電源下で使用することを考慮している。   The AC wire 22 in the space 13 is covered with a pressure-resistant insulating tube 25. When the electrical wiring 2 is connected to a high voltage power source, the insulating tube 25 has a withstand voltage against the AC line 22. That is, it is considered that this refrigerator is exported to a high-voltage power source area with a rated voltage of 200 V or the like and used under this high-voltage power source.

また、上記ＤＣ線２１は、図示しないトランスに接続されている。したがって、高圧電源下でも、この冷蔵庫を安全に使用できる。   The DC line 21 is connected to a transformer (not shown). Therefore, the refrigerator can be used safely even under a high voltage power source.

上記ＤＣ線専用孔部１１ａ，１２ａや上記ＡＣ線専用孔部１１ｂ，１２ｂには、上記ＤＣ線２１や上記ＡＣ線２２との間の隙間を埋めるように、シール材２６が取り付けられている。このシール材２６は、上記断熱材１４を上記空間１３に充填する際に、この断熱材１４が、上記外箱１１の外側や上記内箱１２の内側に、漏れ出すことを防止している。   A sealing material 26 is attached to the DC wire dedicated holes 11a and 12a and the AC line dedicated holes 11b and 12b so as to fill a gap between the DC wire 21 and the AC wire 22. The sealing material 26 prevents the heat insulating material 14 from leaking to the outside of the outer box 11 or the inner box 12 when the space 13 is filled with the heat insulating material 14.

上記構成の電気配線の配列構造によれば、上記ＤＣ線２１と上記ＡＣ線２２は、互いに分離して接触しないように、配列されているので、上記ＤＣ線２１と上記ＡＣ線２２の接触が原因となるノイズの発生が無くなる。   According to the arrangement structure of the electrical wiring of the above configuration, the DC line 21 and the AC line 22 are arranged so as not to contact each other separately, so that the DC line 21 and the AC line 22 are not in contact with each other. The cause of noise is eliminated.

また、上記冷蔵庫を高圧電源下で使用する場合、高圧電源下での耐圧の対応が、上記ＡＣ線２２のみの対応でよくなる。つまり、上記絶縁チューブ２５は、上記ＡＣ線２２のみを被覆すればよくなる。したがって、耐圧対応の作業の簡素化、および、コストの低減を図ることができる。   Further, when the refrigerator is used under a high voltage power source, the voltage resistance under the high voltage power source can be handled only by the AC line 22. That is, the insulating tube 25 only needs to cover the AC wire 22. Therefore, it is possible to simplify the work corresponding to the pressure resistance and reduce the cost.

また、上記外箱１１は、上記ＤＣ線専用孔部１１ａおよび上記ＡＣ線専用孔部１１ｂを有し、上記ＤＣ線２１は、上記ＤＣ線専用孔部１１ａから、上記外箱１１の外側に引き出される一方、上記ＡＣ線２２は、上記ＡＣ線専用孔部１１ｂから、上記外箱１１の外側に引き出されるので、上記ＤＣ線２１と上記ＡＣ線２２の接触を確実に防止できる。また、上記外箱１１の外側に引き出された上記ＤＣ線２１と上記ＡＣ線２２を確実に区別できて、電気部品との誤配線を防止できる。   The outer box 11 has the DC line dedicated hole 11a and the AC line dedicated hole 11b, and the DC line 21 is drawn out of the outer box 11 from the DC line dedicated hole 11a. On the other hand, since the AC line 22 is pulled out from the AC line dedicated hole 11b to the outside of the outer box 11, the contact between the DC line 21 and the AC line 22 can be reliably prevented. In addition, the DC line 21 and the AC line 22 drawn to the outside of the outer box 11 can be reliably distinguished, and erroneous wiring with electrical components can be prevented.

また、上記内箱１２は、上記ＤＣ線専用孔部１２ａおよび上記ＡＣ線専用孔部１２ｂを有し、上記ＤＣ線２１は、上記ＤＣ線専用孔部１２ａから、上記内箱１２の内側に引き出される一方、上記ＡＣ線２２は、上記ＡＣ線専用孔部１２ｂから、上記内箱１２の内側に引き出されるので、上記ＤＣ線２１と上記ＡＣ線２２の接触を確実に防止できる。また、上記内箱１２の内側に引き出された上記ＤＣ線２１と上記ＡＣ線２２を確実に区別できて、電気部品との誤配線を防止できる。   The inner box 12 has the DC line dedicated hole 12a and the AC line dedicated hole 12b, and the DC line 21 is led out from the DC line dedicated hole 12a to the inside of the inner box 12. On the other hand, since the AC line 22 is pulled out from the AC line dedicated hole 12b to the inside of the inner box 12, the contact between the DC line 21 and the AC line 22 can be reliably prevented. In addition, the DC line 21 and the AC line 22 drawn out to the inside of the inner box 12 can be reliably distinguished, and erroneous wiring with electrical components can be prevented.

また、上記電気配線２は、高圧電源に接続されるので、高圧電源下での耐圧の対応が、上記ＡＣ線２２のみの対応でよくなって、耐圧対応の作業の簡素化、および、コストの低減を図ることができる。   In addition, since the electric wiring 2 is connected to a high voltage power source, it is only necessary to deal with the withstand voltage under the high voltage power source by dealing with the AC line 22, simplifying the work for dealing with the withstand voltage, and reducing the cost. Reduction can be achieved.

また、上記構成の冷蔵庫によれば、上記電気配線の配列構造を備えるので、ノイズの発生を防止すると共に、製造工程および製造コストの低減を図ることができる。   Moreover, according to the refrigerator having the above-described configuration, since the electric wiring arrangement structure is provided, the generation of noise can be prevented and the manufacturing process and the manufacturing cost can be reduced.

なお、この発明は上述の実施形態に限定されない。例えば、上記外箱１１や上記内箱１２には、上記ＤＣ線専用孔部１１ａ，１２ａや上記ＡＣ線専用孔部１１ｂ，１２ｂの代わりに、上記ＤＣ線２１および上記ＡＣ線２２を同時に挿通しても上記ＤＣ線２１と上記ＡＣ線２２が互いに接触しないような孔部を設けてもよい。また、上記電気配線の配列構造を、冷蔵庫以外に、電子レンジ、洗濯機や掃除機などの家庭用の電気機器に用いてもよい。   In addition, this invention is not limited to the above-mentioned embodiment. For example, the DC line 21 and the AC line 22 are simultaneously inserted into the outer box 11 and the inner box 12 instead of the DC line dedicated holes 11a and 12a and the AC line dedicated holes 11b and 12b. Alternatively, a hole may be provided so that the DC wire 21 and the AC wire 22 do not contact each other.
