In other words, the imaging camera 22 is for realizing an additional function instead of the above-described original function of the refrigerator 2, and it is not necessary to operate alone if the communication device 7 is not operating. is there.
- Refrigerator 2 has a power consumption of about several tens of watts during normal operation, and has a lower power consumption per unit time than a household electric appliance such as a microwave oven. Are in many categories. For this reason, various measures for reducing power consumption are applied to household electrical appliances that are constantly powered and used like the refrigerator 2. However, since the power is always supplied, even if the power consumption per unit time during the normal operation of the communication device 7 is about 1 W or less, for example, if the power is always supplied, the integrated value of the power consumption is To increase. By providing the communication device 7 and connecting it to the home network, it is possible to realize a convenient function (such as being able to see images in the warehouse from a remote location), but for users who do not use that function Therefore, power consumption increases in unnecessary portions.
- the refrigerator 2 suppresses an increase in unnecessary power consumption as follows.

- power supply to the functional unit 30 including the communication device 7 is interrupted, so that unnecessary power consumption can be reduced to zero. Since the nonvolatile memory 16 that stores the setting as to whether or not to permit the operation of the function unit 30 is provided, once the setting for permitting the operation of the function unit 30 (that is, using the function unit 30) is performed, Even if the power supply to the refrigerator 2 is temporarily interrupted, the functional unit 30 can be used without resetting if the power supply is resumed.
- the operation for permitting the operation of the functional unit 30 can be performed from the operation panel 8, it can be arbitrarily set by the refrigerator 2 alone, and is convenient for the user who wants to use the functional unit 30. Will not drop. Since the refrigerator 2 is used in a state where power is constantly supplied, if the function unit 30 is set to be used in the initial state, a user who does not use the function unit 30 or the function unit 30 operates without permission. For a user who did not think that, only the power consumption increased. Therefore, such a meaningless increase in power consumption can be eliminated by setting the function unit 30 not to be used at the time of factory shipment as in the present embodiment.

Abstract
Description
本発明が解決しようとする課題は、通信手段を有する構成において無意味な消費電力の増加を抑制することができる家電機器を提供することである。
図1に示すように、本実施形態の家電機器を適用した家電ネットワーク1は、家電機器としての冷蔵庫2、冷蔵庫2との間で無線通信方式にて通信を行う無線ルータ3、冷蔵庫2との間または無線ルータ3との間で無線通信方式にて通信を行う通信端末4、無線ルータ3に接続されているネットワーク5、ネットワーク5に接続されているサーバ6を備えている。また、冷蔵庫2は、ネットワーク5を介して通信端末4と通信することも可能である。これら無線ルータ3、通信端末4、サーバ6は、特許請求の範囲に記載した外部の装置に相当する。
一方、通信側電源回路19は、通信装置7およびその通信装置7を利用して作動する通信関連機能部(以下、便宜的に、通信装置7も含めて機能部30と称する)用の電源回路であり、主制御部10からの指示に基づいて、通信装置7を含む機能部30に対して電源供給を行う。電源制御回路17は、主制御部10とともに、特許請求の範囲に記載した電源制御部を構成している。
冷蔵庫2は、通常運転時の消費電力が数十W程度であり、電子レンジ等の家電機器に比べれば単位時間当たりの消費電力は少ないものの、常時給電されていることから、積算の消費電力としては多い部類に入る。そのため、冷蔵庫2のように常時給電されて使用される家電機器は、消費電力を下げるための様々な対策が施されている。しかし、常時給電されていることから、通信装置7の通常動作時の単位時間当たりの消費電力が例えば1W以下程度であったしても、常時給電されてしまうと、その消費電力の積算値が増加する。通信装置7を設けて家庭内ネットワークに接続することにより、便利な機能(例えば遠隔地から庫内の画像を見ることができる等)を実現することはできる反面、その機能を使用しないユーザにとっては、不要な部分で消費電力が増加することになる。
冷蔵庫2は、図3に示す利用設定処理において、機能部30を利用する旨の設定が行われると、つまり、通信機能の利用が設定されると(S1:YES)、機能部30側への通電を許可することで、つまり、通信側電源回路19をONする(S2)。これにより、機能部30側への通電が開始され、機能部30が作動可能な状態となる(機能部30の作動が許可される)。このとき、機能部30の作動を許可する旨の設定は、不揮発性メモリ16に記憶されるため、停電等で一時的に冷蔵庫2への給電が遮断された場合であっても、再び通電されれば機能部30をそのまま作動することになる。
以上説明した本実施形態の冷蔵庫2によれば次のような効果を奏する。
冷蔵庫2は、操作パネル8から機能部30の作動を許可する旨の設定が行われるまでは、機能部30の作動を制限する。これにより、機能部30を利用しない場合において、消費電力の増加を抑制することができる。
機能部30の作動を許可するか否かの設定を記憶する不揮発性メモリ16を備えているので、機能部30の作動を許可する(つまり、機能部30を利用する)設定を一度行えば、冷蔵庫2への給電が一時的に遮断されたような場合であっても、給電が再開されれば再設定を行うことなく機能部30を利用することができる。
冷蔵庫2は常時給電された状態で使用されることから、初期状態で機能部30を利用するという設定になっていると、機能部30を使わないユーザや機能部30が勝手に作動しているとは思わなかったユーザにとって、無意味に消費電力だけが増加した状態となってしまう。そのため、本実施形態のように工場出荷時には機能部30を利用しない設定にすることで、そのような無意味な消費電力の増加を解消することができる。
また、通信装置7の作動状態を操作パネル8に表示してユーザに提示するので、無線通信方式を採用している場合であっても、機能部30を利用したいユーザであれば機能部30が作動していることを把握でき、機能部30を利用しないユーザであれば機能部30が作動していないことを把握できるようになる。
本発明は、上記した実施形態にて例示したものに限定されることなく、次のように変形又は拡張することができる。また、以下に示す変形例及び拡張例の一部または全部は、任意に組み合わせることができる。
一実施形態では機能部30として庫内を撮像する撮像カメラ22を例示したが、機能部30は、撮像カメラ22に限定されるものでは無い。例えば、庫外を撮像して見守りシステムを実現するようなものであってもよいし、音声通話等を行うようなものであってもよい。
また、例えば15分おきに通電する等電源供給を断続的に行うモードと、電源供給を連続的に行うモードとを切り替えることで機能部30の作動を許可するか否かを決定し、消費電力の増加を抑制する構成としてもよい。
無線通信方式は、いわゆる無線LANやBluetooth(登録商標)、Wifi(登録商標)など任意の通信方式を採用することができる。また、通信手段としては、LAN、USB(登録商標)、電力線通信など任意の有線通信方式を採用することもできる。
