Abstract
Description
図1は、インターネット等のネットワークを介して通信装置により冷蔵庫を制御するためのシステムの概要を説明する図である。通信装置110は、例えばスマートフォン又はタブレット端末である。通信装置110は、通信装置110とアクセスポイント120との間で無線LAN(Local Area Network)接続を確立して、インターネット等のネットワーク上のサーバ130と通信する。また、冷蔵庫100も、冷蔵庫100とアクセスポイント120との間で無線LAN接続を確立して、ネットワーク上のサーバ130と通信する。
本実施の形態では、急冷機能においてユーザが「冷ます」を指定した場合に急冷ファン316の制御を変更する例を説明する。冷蔵庫100の構成は実施の形態1と同様である。すなわち、冷蔵庫100の構成は図1から図6で説明した構成と同様である。
実施形態1、及び、実施形態2で説明した処理の変形例を説明する。
