Description

この発明は、例えば、庫内灯や除霜制御部の電気部品を備える冷蔵庫に関する。   The present invention relates to, for example, a refrigerator including an interior lamp and an electrical component of a defrost control unit.

従来より、冷蔵庫は、タイマの積算時間によって冷却運転と除霜運転とを切り替える除霜制御部を、冷蔵室内に設けている（特開平７−９８１７１号公報：特許文献１参照）。   2. Description of the Related Art Conventionally, refrigerators are provided with a defrost control unit that switches between a cooling operation and a defrosting operation according to an accumulated time of a timer (see JP-A-7-98171: Patent Document 1).

上記除霜制御部は、除霜側コネクタを介して、電源回路（電源コード）の電源側コネクタに接続されている。上記電源側コネクタおよび上記除霜側コネクタが接続された状態で、上記電源側コネクタおよび上記除霜側コネクタ内に、上記除霜制御部と上記電源回路との電気的接続部を形成する。   The defrost control unit is connected to a power supply side connector of a power supply circuit (power cord) via a defrosting side connector. In the state where the power supply side connector and the defrosting side connector are connected, an electrical connection part between the defrosting control unit and the power supply circuit is formed in the power supply side connector and the defrosting side connector.

そして、接続状態の上記電源側コネクタおよび上記除霜側コネクタは、上記冷蔵室内にある。この接続状態の上記電源側コネクタおよび上記除霜側コネクタには、一般的に、０．２Ａ以上の電流が流れている。ここで、耐火の安全上、ＩＥＣ（国際電気標準会議：International Electrotechnical Commission）の規格により、０．２Ａ以上の電流が流れる上記電源側コネクタおよび上記除霜側コネクタにおいて、上記電気的接続部から３ｍｍ以内には、耐火部材が必要である。   And the said power supply side connector and the said defrost side connector of a connection state are in the said refrigerator compartment. Generally, a current of 0.2 A or more flows through the power supply side connector and the defrosting side connector in this connected state. Here, for fire safety, according to the IEC (International Electrotechnical Commission) standard, the power supply side connector and the defrosting side connector through which a current of 0.2 A or more flows are 3 mm from the electrical connection portion. Within, a refractory member is required.

そして、上記冷蔵室内の他の部材が、上記電気的接続部から３ｍｍ内に進入することを防ぐために、接続状態の上記電源側コネクタおよび上記除霜側コネクタの各組の周囲を、それぞれ、難燃性クッション材および耐火性金属テープ等の他の耐火部材で覆っていた。   Then, in order to prevent other members from entering the cold storage chamber from entering the electrical connection portion within 3 mm, the surroundings of each set of the power supply side connector and the defrosting side connector in the connected state are difficult. It covered with other fireproof members, such as a fireproof cushioning material and a fireproof metal tape.

しかし、上記従来の冷蔵庫では、上記冷蔵室内において、接続状態の上記電源側コネクタおよび上記除霜側コネクタの各組を、それぞれ、他の耐火部材で覆っていたので、耐火部材の数量が多く、手間がかかり、コスト高であった。
特開平７−９８１７１号公報 However, in the conventional refrigerator, since each set of the power supply side connector and the defrosting side connector in the connected state is covered with another fireproof member in the refrigerator, the number of fireproof members is large. It was time consuming and expensive.
JP-A-7-98171

そこで、この発明の課題は、耐火部材の数量を削減し、手間を省き、コストを低減しつつ、国際安全規格を満たす冷蔵庫を提供することにある。   Then, the subject of this invention is providing the refrigerator which satisfy | fills international safety standards, reducing the quantity of a fireproof member, saving a trouble, and reducing cost.

上記課題を解決するため、この発明の冷蔵庫は、
冷蔵室を有する冷蔵庫本体と、
上記冷蔵庫本体の外側に設けられると共に耐火性を有する電気部品収納箱と、
電源回路の電源側コネクタに部品側コネクタを介して接続される電気部品と
を備え、
上記冷蔵室内に配置されている上記電気部品および上記部品側コネクタは、０．２Ａ未満の電流が流れる上記電気部品および上記部品側コネクタである一方、
上記電気部品収納箱内に配置されている上記電気部品および上記部品側コネクタは、少なくとも、０．２Ａ以上の電流が流れる上記電気部品および上記部品側コネクタであることを特徴としている。 In order to solve the above problems, the refrigerator of the present invention is
A refrigerator body having a refrigerator compartment;
An electrical component storage box provided on the outside of the refrigerator body and having fire resistance,
An electrical component connected to the power supply side connector of the power supply circuit via the component side connector,
While the electrical component and the component side connector arranged in the refrigerator compartment are the electrical component and the component side connector through which a current of less than 0.2 A flows,
The electrical component and the component-side connector arranged in the electrical component storage box are at least the electrical component and the component-side connector through which a current of 0.2 A or more flows.

ここで、上記電源側コネクタおよび上記部品側コネクタが接続された状態で、上記電源側コネクタおよび上記部品側コネクタ内に、上記電気部品と上記電源回路との電気的接続部を形成する。   Here, in a state where the power supply side connector and the component side connector are connected, an electrical connection portion between the electrical component and the power supply circuit is formed in the power supply side connector and the component side connector.

この発明の冷蔵庫によれば、０．２Ａ以上の電流が流れる上記電気部品および上記部品側コネクタは、上記冷蔵室の外側に配置されている。ここで、耐火の安全上、ＩＥＣ（国際電気標準会議：International Electrotechnical Commission）の規格により、０．２Ａ以上の電流が流れる上記電源側コネクタおよび上記部品側コネクタにおいて、上記電気的接続部から３ｍｍ以内には、耐火部材が必要である。   According to the refrigerator of the present invention, the electrical component and the component-side connector through which a current of 0.2 A or more flows are arranged outside the refrigerator compartment. Here, for safety of fire resistance, in the power supply side connector and the component side connector through which a current of 0.2 A or more flows according to the standard of IEC (International Electrotechnical Commission), within 3 mm from the electrical connection portion. Requires a refractory member.

すなわち、上記冷蔵室内には、０．２Ａ以上の電流が流れる上記部品側コネクタがないので、上記冷蔵室内では、他の部材が、上記電気的接続部から３ｍｍ以内に進入することを防ぐ必要がない。要するに、上記冷蔵室内では、互いに接続されている上記電源側コネクタおよび上記部品側コネクタを覆う他の耐火部材は、不要になる。   That is, since there is no component-side connector through which a current of 0.2 A or more flows in the refrigerator compartment, it is necessary to prevent other members from entering within 3 mm from the electrical connection portion in the refrigerator compartment. Absent. In short, in the refrigerating room, the other power-resistant members that cover the power supply side connector and the component side connector that are connected to each other are unnecessary.

また、上記電気部品収納箱内には、０．２Ａ以上の電流が流れる上記部品側コネクタを配置しているので、上記電気部品収納箱によって、接続状態の上記電源側コネクタおよび上記部品側コネクタの複数組を一括して覆うことができて、上記電気部品収納箱によって、上記電源側コネクタおよび上記部品側コネクタの発火時の類焼防止を図ることができる。このように、上記電気部品収納箱内では、接続状態の上記電源側コネクタおよび上記部品側コネクタの各組の周囲を、それぞれ、他の耐火部材で覆う必要がなくて、手間とコストを省くことができる。   Further, since the component side connector through which a current of 0.2 A or more flows is arranged in the electric component storage box, the power component side connector and the component side connector in the connected state are arranged by the electric component storage box. A plurality of sets can be covered together, and the electric component storage box can prevent burning of the power supply side connector and the component side connector during firing. Thus, in the electrical component storage box, it is not necessary to cover the periphery of each set of the power supply side connector and the component side connector in the connected state with another fireproof member, thereby saving labor and cost. Can do.

この一実施形態の冷蔵庫によれば、従来では上記冷蔵室内にあった上記除霜制御部を、上記電気部品収納箱内に移動しているので、上記除霜制御部と上記電源回路とを接続する上記部品側コネクタおよび上記電源側コネクタの周囲を、他の耐火部材によって覆う必要がなくなって、手間とコストを省くことができる。また、使用開始の据付け設置後も、保守や点検時に、上記除霜タイマの動作（例えば、同期モータの回転）を容易に確認できる。   According to the refrigerator of this embodiment, since the defrost control unit that has been conventionally in the refrigerator compartment is moved into the electrical component storage box, the defrost control unit and the power supply circuit are connected. Thus, it is not necessary to cover the component side connector and the power source side connector with another fireproof member, and labor and cost can be saved. In addition, even after installation and installation, the operation of the defrost timer (for example, rotation of the synchronous motor) can be easily confirmed during maintenance and inspection.

また、一実施形態の冷蔵庫では、上記冷蔵室内に配置されている上記電気部品は、庫内灯を含む。   Moreover, in the refrigerator of one Embodiment, the said electrical component arrange | positioned in the said refrigerator compartment contains an interior lamp.

この一実施形態の冷蔵庫によれば、上記庫内灯は、従来から、上記冷蔵室内に配置されているので、上記庫内灯を上記冷蔵室内に新たに設ける必要がない。当然に、上記庫内灯と上記電源回路とを接続する上記部品側コネクタおよび上記電源側コネクタの周囲を、他の耐火部材によって覆う必要がない。   According to the refrigerator of this embodiment, since the interior lamp is conventionally arranged in the refrigerator compartment, it is not necessary to newly provide the interior lamp in the refrigerator compartment. Naturally, it is not necessary to cover the periphery of the component side connector and the power source side connector for connecting the interior lamp and the power supply circuit with other fireproof members.

また、一実施形態の冷蔵庫では、上記電気部品収納箱は、上記電気部品収納箱内に配置されている上記電気部品および上記部品側コネクタと共に、上記冷蔵庫本体から取り外し自在である。   Moreover, in the refrigerator of one Embodiment, the said electrical component storage box is detachable from the said refrigerator main body with the said electrical component and the said component side connector which are arrange | positioned in the said electrical component storage box.

この一実施形態の冷蔵庫によれば、上記電気部品収納箱内の上記電気部品および上記部品側コネクタは、上記電気部品収納箱に一体に組み込まれており、上記電気部品収納箱内の上記電気部品が故障した場合、上記電気部品収納箱を取り外すことで、上記電気部品を同時に取り外すことができ、正常な電気部品への交換が容易になる。   According to the refrigerator of this embodiment, the electrical component and the component-side connector in the electrical component storage box are integrally incorporated in the electrical component storage box, and the electrical component in the electrical component storage box When a failure occurs, the electrical component can be removed at the same time by removing the electrical component storage box, facilitating replacement with a normal electrical component.

この一実施形態の冷蔵庫によれば、上記電気部品収納箱は、上記冷蔵庫本体の凹部に、嵌め込まれているので、上記電気部品収納箱を上記冷蔵庫本体に取り付けた状態で、上記冷蔵庫の背面側の形状を略平坦にできる。このように、上記冷蔵庫を設置したときの上記冷蔵庫の背面側のデッドスペースを小さくできる。   According to the refrigerator of this embodiment, since the electric component storage box is fitted in the recess of the refrigerator main body, the electric component storage box is attached to the refrigerator main body, and the rear side of the refrigerator Can be made substantially flat. Thus, the dead space on the back side of the refrigerator when the refrigerator is installed can be reduced.

この発明の冷蔵庫によれば、上記冷蔵室内には、０．２Ａ未満の電流が流れる上記電気部品および上記部品側コネクタを配置する一方、上記電気部品収納箱内には、少なくとも、０．２Ａ以上の電流が流れる上記電気部品および上記部品側コネクタを配置しているので、耐火部材の数量を削減し、手間を省き、コストを低減しつつ、国際安全規格を満たすことができる。   According to the refrigerator of the present invention, the electrical component and the component-side connector through which a current of less than 0.2 A flows are arranged in the refrigeration chamber, and at least 0.2 A or more in the electrical component storage box. Since the electrical component and the component-side connector through which current flows are arranged, it is possible to meet the international safety standard while reducing the number of fireproof members, saving labor, and reducing costs.

以下、この発明を図示の実施の形態により詳細に説明する。   Hereinafter, the present invention will be described in detail with reference to the illustrated embodiments.

（第１の実施形態）
図１は、この発明の端子接続構造体を適用した冷蔵庫の一実施形態である正面図を示している。図２は、この冷蔵庫の側面断面図を示している。図３は、この冷蔵庫の回路図を示す。 (First embodiment)
FIG. 1: has shown the front view which is one Embodiment of the refrigerator to which the terminal connection structure of this invention is applied. FIG. 2 shows a side sectional view of the refrigerator. FIG. 3 shows a circuit diagram of the refrigerator.

図１と図２に示すように、この冷蔵庫は、冷凍室２および冷蔵室３を有する冷蔵庫本体１と、この冷蔵庫本体１の冷凍室２に取り付けられた冷凍室扉５と、この冷蔵庫本体１の冷蔵室３に取り付けられた冷蔵室扉６とを備える。   As shown in FIGS. 1 and 2, the refrigerator includes a refrigerator main body 1 having a freezer compartment 2 and a refrigerator compartment 3, a freezer compartment door 5 attached to the freezer compartment 2 of the refrigerator main body 1, and the refrigerator main body 1. The refrigerator compartment door 6 attached to the refrigerator compartment 3 is provided.

上記冷凍室２と上記冷蔵室３とは、仕切り壁４によって区切られている。この仕切り壁４には、上記冷蔵室扉６の開閉により動作するドアスイッチ１３が取り付けられている。   The freezer compartment 2 and the refrigerator compartment 3 are separated by a partition wall 4. A door switch 13 that operates by opening and closing the refrigerator compartment door 6 is attached to the partition wall 4.

上記冷凍室２の後方奥側には、取付板２２が設けられ、この取付板２２の後面には、冷却循環用のファンモータ(冷却用ファンモータ)８と、このファンモータ８の下方に配置された冷却器９とが、取り付けられている。上記冷却器９の下部には、霜取り用の除霜ヒータ(電気ヒータ)１４が設置されている。   A mounting plate 22 is provided behind the freezer compartment 2, and a cooling circulation fan motor (cooling fan motor) 8 is disposed on the rear surface of the mounting plate 22 and below the fan motor 8. The cooled cooler 9 is attached. A defrosting heater (electric heater) 14 for defrosting is installed below the cooler 9.

上記冷蔵庫本体１の外側には、耐火性を有する電気部品収納箱３０が設けられている。すなわち、上記電気部品収納箱３０は、上記冷蔵庫本体１の外側の取付部材１７に、取り付けられている。上記電気部品収納箱３０内には、除霜制御部１５が配置されている。   An electrical component storage box 30 having fire resistance is provided outside the refrigerator body 1. That is, the electric component storage box 30 is attached to the attachment member 17 outside the refrigerator main body 1. A defrost control unit 15 is disposed in the electrical component storage box 30.

図１、図２および図３に示すように、上記除霜制御部１５は、時間を積算する除霜タイマ１５ａと、冷却運転と除霜運転とを切り替える除霜スイッチ１５ｂとを有する。   As shown in FIGS. 1, 2, and 3, the defrosting control unit 15 includes a defrosting timer 15 a that integrates time, and a defrosting switch 15 b that switches between a cooling operation and a defrosting operation.

そして、上記除霜タイマ１５ａの積算時間により、上記除霜スイッチ１５ｂの接点が切り替わって、冷却回路から除霜回路に通電制御されて、上記除霜ヒータ１４は、発熱を始める。   Then, the contact point of the defrost switch 15b is switched according to the accumulated time of the defrost timer 15a, and energization control is performed from the cooling circuit to the defrost circuit, and the defrost heater 14 starts to generate heat.

上記除霜ヒータ１４は、温度を上昇して、上記冷却器９の霜と氷を融解させると、上記冷却器９の上部に配置された除霜サーモスタット１６により、温度を検知されて、上記除霜ヒータ１４の発熱を停止する。その後、上記除霜スイッチ１５ｂの接点が、再び、除霜回路から冷却回路に切り替わって、通常の冷却運転を始める。   When the temperature of the defrosting heater 14 is increased and the frost and ice of the cooler 9 are melted, the temperature is detected by the defrosting thermostat 16 disposed on the upper side of the cooler 9, and the defrosting heater 14 is removed. Heat generation of the frost heater 14 is stopped. Thereafter, the contact point of the defrost switch 15b is switched again from the defrost circuit to the cooling circuit, and normal cooling operation is started.

上記冷蔵室３の後方奥側の内面には、カバー部材２３が設けられ、このカバー部材２３の内部に、庫内照明用の庫内灯１１が庫内灯係止器具１０にて設置されている。   A cover member 23 is provided on the inner surface on the rear rear side of the refrigerator compartment 3, and an interior lamp 11 for interior illumination is installed in the interior of the cover member 23 by an interior lamp locking device 10. Yes.

上記冷蔵庫本体１の背面には、冷媒圧縮用の圧縮機(冷却用圧縮電動機)１２が設置されている。この圧縮機１２は、上記冷凍室２の内部に設置されたサーモスタット７の温度検知によって、このサーモスタット７の電気接点で、ＯＮ／ＯＦＦを断続運転して、庫内を一定温度に保つ。   On the back surface of the refrigerator main body 1, a refrigerant compression compressor (cooling compression motor) 12 is installed. The compressor 12 intermittently operates on / off at the electrical contacts of the thermostat 7 by detecting the temperature of the thermostat 7 installed in the freezer compartment 2 to keep the inside of the refrigerator at a constant temperature.

図３に示すように、この冷蔵庫の電源回路は、冷却回路と除霜回路とを有する。なお、上記冷却回路と上記除霜回路とは、同時に、電流が流れない。   As shown in FIG. 3, the power supply circuit of this refrigerator has a cooling circuit and a defrosting circuit. Note that no current flows through the cooling circuit and the defrosting circuit at the same time.

上記冷却回路において、上記圧縮機１２の動作電流は、２３０Ｖ定格電圧にて、約１．２Ａとなる。すなわち、上記サーモスタット７および上記除霜制御部１５を経由して、電源から上記圧縮機１２までの冷却回路が形成され、冷却時には、約１．２Ａの電流が流れる。すなわち、上記冷却回路には、０．２Ａ以上の電流が流れる。   In the cooling circuit, the operating current of the compressor 12 is about 1.2 A at a rated voltage of 230V. That is, a cooling circuit from the power source to the compressor 12 is formed via the thermostat 7 and the defrost control unit 15, and a current of about 1.2 A flows during cooling. That is, a current of 0.2 A or more flows through the cooling circuit.

上記除霜回路において、上記除霜ヒータ１４の動作電流は、２３０Ｖ定格電圧にて、約０．６Ａとなる。すなわち、上記除霜ヒータ１４および上記除霜制御部１５を経由して、電源から上記除霜ヒータ１４までの除霜回路が形成され、除霜時には、約０．６Ａの電流が流れる。すなわち、上記除霜回路には、０．２Ａ以上の電流が流れる。   In the defrosting circuit, the operating current of the defrosting heater 14 is about 0.6 A at a rated voltage of 230V. That is, a defrosting circuit from the power source to the defrosting heater 14 is formed via the defrosting heater 14 and the defrosting control unit 15, and a current of about 0.6 A flows during defrosting. That is, a current of 0.2 A or more flows through the defrost circuit.

上記庫内灯１１の動作電流は、２３０Ｖ定格電圧にて、約０．０５Ａとなる。すなわち、上記庫内灯１１には、０．２Ａ未満の電流が流れる。   The operating current of the interior lamp 11 is about 0.05 A at a rated voltage of 230V. That is, a current of less than 0.2 A flows through the interior lamp 11.

具体的に述べると、上記サーモスタット７、上記ファンモータ８、上記冷却器９、上記庫内灯１１、上記圧縮機１２、上記ドアスイッチ１３、上記除霜ヒータ１４、上記除霜制御部１５または上記除霜サーモスタット１６等の電気部品は、部品側コネクタを介して、電源回路（電源コード）の電源側コネクタに接続される。   Specifically, the thermostat 7, the fan motor 8, the cooler 9, the interior lamp 11, the compressor 12, the door switch 13, the defrost heater 14, the defrost control unit 15 or the above Electrical components such as the defrost thermostat 16 are connected to the power supply side connector of the power supply circuit (power supply cord) via the component side connector.

ここで、上記電源側コネクタおよび上記部品側コネクタが接続された状態で、上記電源側コネクタおよび上記部品側コネクタ内に、上記電気部品と上記電源回路との電気的接続部を形成する。   Here, in a state where the power supply side connector and the component side connector are connected, an electrical connection portion between the electrical component and the power supply circuit is formed in the power supply side connector and the component side connector.

そして、耐火の安全上、ＩＥＣ（国際電気標準会議：International Electrotechnical Commission）の規格により、０．２Ａ以上の電流が流れる上記電源側コネクタおよび上記部品側コネクタにおいて、上記電気的接続部から３ｍｍ以内には、耐火部材が必要である。   For fire safety, in accordance with the IEC (International Electrotechnical Commission) standard, the power supply side connector and the component side connector through which a current of 0.2 A or more flows are within 3 mm from the electrical connection portion. Requires a refractory member.

上記冷蔵室３内に配置されている上記電気部品および上記部品側コネクタは、０．２Ａ未満の電流が流れる上記庫内灯１１および庫内灯側コネクタである。   The electrical component and the component side connector arranged in the refrigerator compartment 3 are the interior lamp 11 and the interior light side connector through which a current of less than 0.2 A flows.

このように、上記冷蔵室３内では、他の部材が、上記電気的接続部から３ｍｍ以内に進入することを防ぐ必要がない。すなわち、上記庫内灯１１と上記電源回路とを接続する上記庫内灯側コネクタおよび上記電源側コネクタの周囲を、他の耐火部材によって覆う必要がない。要するに、上記冷蔵室３内では、互いに接続されている上記電源側コネクタおよび上記部品側コネクタを覆う他の耐火部材は、不要になる。   Thus, in the refrigerator compartment 3, it is not necessary to prevent other members from entering within 3 mm from the electrical connection portion. That is, it is not necessary to cover the interior lamp side connector for connecting the interior lamp 11 and the power supply circuit and the periphery of the power supply side connector with another fireproof member. In short, in the refrigerating room 3, the other fireproof members that cover the power supply side connector and the component side connector connected to each other are unnecessary.

なお、上記冷蔵室３内には、上記庫内灯１１および上記庫内灯側コネクタ以外の電気部品および部品側コネクタを配置してもよいが、上記電気部品および上記部品側コネクタは、０．２Ａ未満の電流が流れる電気部品および部品側コネクタに限定される。   In the refrigerator compartment 3, electrical components and component side connectors other than the interior light 11 and the interior light side connector may be arranged. It is limited to electrical components and component-side connectors through which current less than 2A flows.

一方、上記電気部品収納箱３０内に配置されている上記電気部品および上記部品側コネクタは、０．２Ａ以上の電流が流れる上記除霜制御部１５および除霜制御部側コネクタである。   On the other hand, the electrical component and the component side connector arranged in the electrical component storage box 30 are the defrost control unit 15 and the defrost control unit side connector through which a current of 0.2 A or more flows.

具体的に述べると、図４の断面図に示すように、上記除霜制御部１５および上記除霜制御部側コネクタ１８は、上記電気部品収納箱３０内に、一体に組み込まれている。そして、上記電源側コネクタ１９は、上記電気部品収納箱３０内で、上記除霜制御部側コネクタ１８に接続される。   More specifically, as shown in the cross-sectional view of FIG. 4, the defrost control unit 15 and the defrost control unit side connector 18 are integrated into the electrical component storage box 30. The power supply side connector 19 is connected to the defrost control unit side connector 18 in the electrical component storage box 30.

上記電気部品収納箱３０、上記除霜制御部側コネクタ１８および上記電源側コネクタ１９は、例えば、耐火樹脂の材料からなる。この耐火樹脂の材料は、例えば、ＩＥＣの規格を満たす材料であって、グローワイヤ燃焼性指数(GWFI:grow-wire flammability index)８５０℃及びグローワイヤ着火温度(GWIT:grow-wire igntion temperature)７７５℃に適合する材料である。   The electrical component storage box 30, the defrost control unit side connector 18, and the power supply side connector 19 are made of, for example, a fireproof resin material. The material of the refractory resin is, for example, a material that satisfies the IEC standards, and includes a glow-wire flammability index (GWFI) of 850 ° C. and a glow-wire ignition temperature (GWIT) of 775. It is a material compatible with ℃.

なお、図示しないが、上記電気部品収納箱３０には、上記除霜制御部１５以外に、電子基板、運転コンデンサ、電源コードの機内接続部、および、上記電気部品の接続電線等を収納してもよい。   Although not shown, in addition to the defrost control unit 15, the electrical component storage box 30 stores an electronic board, an operating capacitor, an in-machine connection portion of a power cord, a connection wire of the electrical component, and the like. Also good.

要するに、上記電気部品収納箱３０内には、上記除霜制御部１５以外に、０．２Ａ以上の電流が流れる他の上記電気部品および他の上記部品側コネクタを配置してもよい。また、上記電気部品収納箱３０内には、上記除霜制御部１５以外に、０．２Ａ未満の電流が流れる電気部品および部品側コネクタを配置してもよい。   In short, in the electrical component storage box 30, in addition to the defrost control unit 15, other electrical components and other component-side connectors through which a current of 0.2 A or more flows may be arranged. In addition to the defrost control unit 15, an electrical component and a component-side connector through which a current of less than 0.2 A flows may be disposed in the electrical component storage box 30.

このように、上記電気部品収納箱３０内には、０．２Ａ以上の電流が流れる上記部品側コネクタ（例えば、上記除霜制御部側コネクタ１８）を配置しているので、上記電気部品収納箱３０によって、接続状態の上記電源側コネクタおよび上記部品側コネクタの複数組を一括して覆うことができて、上記電気部品収納箱３０によって、上記電源側コネクタおよび上記部品側コネクタの発火時の類焼防止を図ることができる。   Thus, since the component side connector (for example, the defrosting control unit side connector 18) through which a current of 0.2 A or more flows is arranged in the electric component storage box 30, the electric component storage box 30 can collectively cover a plurality of sets of the power-side connector and the component-side connector in a connected state, and the electric component storage box 30 can ignite the power-side connector and the component-side connector at the time of firing. Prevention can be achieved.
