Abstract
Description
本発明はインターネット等の通信網を利用した家電機器サービスシステムに好適な無線通信システム及び家電機器に関するものである。 The present invention relates to a wireless communication system and a home appliance suitable for a home appliance service system using a communication network such as the Internet.
一般にインターネット等の通信網を介して家電機器とデータをやり取りし、家電機器の利便性を向上させたシステムがみられる。例えば冷蔵庫をインターネットに接続し、故障内容をサービス業者に伝達して、的確な故障修理を可能にするようにしたものが提案されている(例えば、特許文献1参照)。 In general, there is a system in which data is exchanged with home appliances via a communication network such as the Internet to improve convenience of the home appliances. For example, a refrigerator that connects a refrigerator to the Internet and transmits the content of the failure to a service provider to enable accurate failure repair has been proposed (for example, see Patent Document 1).
このようなシステムに使用する機器としては冷蔵庫に限らず、他の家電品でも同様のものが多くみられる。そして、このような機器はいわゆるネット家電と称され、近年通信インフラの整備、携帯端末の進化を受けて、ますますの広がりを見せ、家庭内にある複数の家電機器にこのような通信機能が装備されていくことが予測される。 The devices used in such a system are not limited to refrigerators, and other home appliances are often the same. Such devices are called so-called Internet home appliances, and in recent years, with the development of communication infrastructure and the evolution of mobile terminals, they have become more and more widespread. Expected to be equipped.
上記家電機器のデータ化が進められていく中において、一般に白物家電と呼ばれる機器は日常生活のなかで、老若男女に関わらず使用されることから、その使いやすさがとても重要視される。すなわち、単独の冷蔵庫がインターネットに接続されているだけであれば、使用性の問題はなく、そのサービスを十分に享受できる。しかしながら、家電のデータ化が広まり複数の家電機器がインターネットに接続されてサービス対象となると、機器データの双方向のやり取りの中で、対象の機器がどの固体を示しているのか、子供やお年寄りにはわかりづらく、使いにくいという課題が生じる。また、家庭内に2台の冷蔵庫を保有している場合などで、冷蔵庫の庫内温度設定を間違えて操作してしまうなどの問題も予見される。 As the above-mentioned home appliances are being converted into data, devices called white goods are generally used in daily life, regardless of age or gender, and so their ease of use is very important. That is, as long as a single refrigerator is only connected to the Internet, there is no problem in usability and the service can be fully enjoyed. However, when data conversion of home appliances spreads and multiple home appliances are connected to the Internet and become a service target, what kind of solid the target device shows in bidirectional exchange of device data, such as children and the elderly Is difficult to understand and difficult to use. In addition, for example, when two refrigerators are held in the home, a problem that the temperature inside the refrigerator is set incorrectly can be predicted.
また、セキュリティ面での対策も大きな課題となってくる。すなわち、非常に高度なセキュリティで保護されている行政機関などのシステムでもサイバー被害を受ける現実を考えると、家電機器のデータ化により家庭内の機器とデータが被害にあう可能性は十分に考えられる。例えば、機器のデータが流出するリスクや機器を勝手に制御されてしまうリスクが存在する。様々なセキュリティ技術により防衛する手段が社会的に講じられているものの、特に機器を勝手に設定変更されたりすると製品の基本機能が損なわれる問題が発生する可能性がある。 In addition, security measures are also a major issue. In other words, considering the reality that even a system such as an administrative organization protected by a very high level of security can suffer cyber damage, there is a good chance that home appliance data will cause damage to home equipment and data. . For example, there is a risk that device data will be leaked and a risk that the device will be controlled without permission. Although measures to protect by various security technologies are socially taken, there is a possibility that the basic function of the product may be impaired especially when the setting is changed without permission.
そこで本発明者らは例えば冷蔵庫本体にRFID(Radio Frequency IDentification)タグを設け、このRFIDタグに携帯端末を近づけることによって、冷蔵庫本体と携帯端末との間でデータをやりとりし、携帯端末を経由してインターネット通信する通信システムと冷蔵庫を考え、すでに提案した。 Therefore, the present inventors, for example, provide an RFID (Radio Frequency IDentification) tag in the refrigerator main body, and by bringing the portable terminal closer to the RFID tag, the data is exchanged between the refrigerator main body and the portable terminal, via the portable terminal. We have already proposed a communication system and refrigerator for internet communication.
この通信システムと冷蔵庫は、RFIDタグという超近接通信を用いて通信を行うようにしたから、対象機器を間違って判別することがなく、一般的な無線通信を行うシステムのような固体判別の問題はなくなり、使用性が向上するとともに、携帯端末によってRF
IDタグのデータを直接読み取るのでインターネットのような通信網を介してデータを読み取る場合のようなセキュリティの問題もなくなり、安全性も向上する。加えて、冷蔵庫自体にインターネット通信のための通信機能等の高価な構成を付加しなくても携帯電話等の携帯端末を介してインターネットと接続し、サービスを提供することができる。
Since this communication system and the refrigerator communicate with each other using ultra-close proximity communication called an RFID tag, there is no problem of identifying individual devices such as a system that performs general wireless communication without erroneously identifying a target device. The usability is improved and the mobile terminal makes RF
Since the data of the ID tag is directly read, there is no security problem as in the case of reading the data via a communication network such as the Internet, and the safety is improved. In addition, a service can be provided by connecting to the Internet via a mobile terminal such as a mobile phone without adding an expensive configuration such as a communication function for Internet communication to the refrigerator itself.
しかしながら発明者らが被験者の協力を得て行った実証実験によると、上記のような安全性、低コスト化の効果が得られることは確認できたが、冷蔵庫に設けたRFIDタグからなる無線送受信部の位置が分かりづらく、使い勝手面で改良の必要性が見られた。特に、初めて無線通信をしようとするときや子供等が使用する時には、携帯端末を接近させタッチさせる場所、すなわち無線送受信部の位置が特定できないという事態が散見された。 However, according to the verification experiment conducted by the inventors with the cooperation of the subjects, it was confirmed that the effects of safety and cost reduction as described above were obtained, but wireless transmission / reception composed of an RFID tag provided in the refrigerator was confirmed. The location of the parts was difficult to understand, and there was a need for improvement in terms of usability. In particular, when wireless communication is attempted for the first time or when a child or the like uses the mobile terminal, the location where the mobile terminal is brought into close contact with, that is, the position of the wireless transmission / reception unit cannot be specified.
また、これまでの家電品機器、例えばエアコン等においては通信手段としてリモコンが一般に浸透しているが、このリモコンは通常リモコンの先端部をエアコン等の家電機器本体の受信部に向けて送信する動作となっている。そのため、今回の被験者の行動を観察していると、被験者は従来のリモコンと同様、携帯端末の先端部を冷蔵庫本体の送受信部に向けて送受信しようとすることが多く、送受信させる動作のわかりにくさも改良する必要性がみられた。特に、白物家電のような電子機器に強くないユーザを対象としているものにあってはこの操作性の改善は必須要件となる。 In addition, a remote control is generally permeated as a communication means in conventional home appliances such as air conditioners, etc., but this remote control usually transmits the front end of the remote control to the receiver of the home appliance main body such as an air conditioner. It has become. Therefore, when observing the behavior of the subject this time, the subject often tries to transmit / receive the tip of the mobile terminal toward the transmission / reception unit of the refrigerator main body, as in the case of the conventional remote control. There was a need to improve the stiffness. In particular, this improvement in operability is an indispensable requirement for users who are not strong against electronic devices such as white goods.
本発明はこのような点に鑑みてなしたもので、高価な通信機能を付加することなく使用性とセキュリティ安全性の高いインターネット通信ができ、かつ、家電機器側の無線送受信部の位置が容易に特定できて使い勝手の良い無線通信システム及び家電機器を提供するものである。 The present invention has been made in view of such points, and can perform Internet communication with high usability and security safety without adding an expensive communication function, and the position of the wireless transmission / reception unit on the home appliance side is easy. It is possible to provide a wireless communication system and home appliances that can be specified easily and easily.
前記課題を解決するために本発明は、携帯端末と前記携帯端末とRFID無線通信を行う家電機器とより構成される通信システムであって、前記家電機器は、携帯端末との間でRFID無線通信を行う家電機器側無線送受信部と、前記無線送受信部に設けられていて当該無線送受信部へタッチを想起させる図形と、を有し、前記携帯端末は、家電機器とRFID無線通信を行う携帯端末側無線送受信部と、前記携帯端末のデータを表示する表示部とを備え、前記携帯端末側無線送受信部が前記家電機器側無線送受信部とデータ通信を行う場合には、前記表示部に前記家電機器側無線送受信部の図形と類似する概念を想起する図形を表示する構成としてある。 In order to solve the above-described problems, the present invention provides a communication system including a mobile terminal and a home appliance that performs RFID wireless communication with the mobile terminal, and the home appliance includes RFID wireless communication with a mobile terminal.

The figure 22a is a back portion facing the mobile terminal side wireless transmission / reception unit 33 provided in the mobile terminal 22, that is,
The information is displayed on a part of the back surface of the mobile terminal side wireless transmitting / receiving unit 33 of the display unit 39.
また、この携帯端末は携帯端末側無線送受信部33の第1通信部33aによりデータを受信すると、表示制御部37が表示部39の表示を切り替えて第1通信部33aにより受信したデータを表示部39に表示させる。すなわち携帯端末の携帯端末側無線送受信部33を冷蔵庫側無線送受信部21に近づけてタッチさせることによって、冷蔵庫側無線送受信部21からの扉開閉回数等のデータを受信し、携帯端末22の表示部39に表示することができる構成としてある。 In addition, when the mobile terminal receives data by the first communication unit 33a of the mobile terminal side wireless transmission / reception unit 33, the display control unit 37 switches the display of the display unit 39 and displays the data received by the first communication unit 33a. 39 is displayed. That is, when the portable terminal side wireless transmission / reception unit 33 of the portable terminal is touched close to the refrigerator side wireless transmission / reception unit 21, data such as the door opening / closing frequency from the refrigerator side wireless transmission / reception unit 21 is received, and the display unit of the portable terminal 22 is received. 39 can be displayed.
更に、上記携帯端末22は普通のスマートフォンと同様、第2通信部34によってインターネット回線(図示せず)を介して各種データを取り込めるようになっており、そのうちの一つに本発明に関係する冷蔵庫の制御データ、例えば設定温度データを取り込み、冷蔵庫の冷蔵庫側無線送受信部21に送信できるようになっている。 Further, the mobile terminal 22 can take various data via the Internet line (not shown) by the second communication unit 34 as in the case of an ordinary smartphone, and one of them is a refrigerator related to the present invention. Control data, for example, set temperature data, can be captured and transmitted to the refrigerator-side wireless transceiver 21 of the refrigerator.
上記構成において、以下その動作を図6の制御フローを用いながら説明する。まず、使用者が食品の出し入れのために冷蔵庫の扉、例えば冷蔵室2の右側扉11bを開成すると、ステップ1において扉開閉検出部23が扉開閉を検出し、ステップ2において回数カウント部24が回数をカウントし、回数記憶部25に記憶するとともに、時間記憶部27が扉開成時間を累計記憶していく。 In the above configuration, the operation will be described below using the control flow of FIG. First, when a user opens a refrigerator door, for example, the right door 11b of the refrigerator compartment 2 for taking in and out food, in step 1, the door opening / closing detection unit 23 detects the door opening / closing, and in step 2, the frequency counting unit 24 The number of times is counted and stored in the number-of-times storage unit 25, and the time storage unit 27 accumulates and stores the door opening time.
そしてステップ3において、近接通信検出部29がデータ要求されているか否かを確認し、要求がなければ後述する制御データ有無、異常有無等の確認ステップを経由してステップ4で1日(24h)が経過したかを確認し、経過していなければステップ1にもどるとともに、経過すれば前日情報記憶部30に扉開閉回数データと扉開成累計時間データを記憶した後、ステップ5にてそれまで記憶していた扉開閉回数をリセットし、ステップ1に戻る。 In step 3, the proximity communication detection unit 29 confirms whether data is requested. If there is no request, one day (24h) in step 4 passes through a confirmation step for the presence / absence of control data and the presence / absence of abnormality, which will be described later. If it has not elapsed, the process returns to step 1. If it has elapsed, the door opening / closing count data and the door opening accumulated time data are stored in the previous day information storage unit 30 and then stored in step 5 so far. Reset the door opening / closing frequency, and return to Step 1.
このような状態で使用者が携帯端末22の無線通信用アプリを起動してその表示部39に表示される図形22aと相似する図形が表示されている冷蔵庫側の冷蔵庫側無線送受信部21にタッチする、すなわちデータ要求信号を送信する(ステップ6)と、近接通信検出部29がステップ3でこれを検出し冷蔵庫側無線送受信部21が動作を開始し、冷蔵庫側無線送受信部21がステップ7で回数記憶部25、時間記憶部27に記憶している扉開閉回数及び扉開成累計時間データを取得し、ステップ8においてそのデータを送信する。そして、ステップ9において報知部31が動作を開始してデータ送信の間点灯し、これを報知する。 In this state, the user activates the wireless communication application of the mobile terminal 22 and touches the refrigerator-side wireless transceiver 21 on the refrigerator side on which a graphic similar to the graphic 22a displayed on the display unit 39 is displayed. When the data request signal is transmitted (step 6), the proximity communication detection unit 29 detects this in step 3, the refrigerator side wireless transmission / reception unit 21 starts operating, and the refrigerator side wireless transmission / reception unit 21 operates in step 7. The door opening / closing times and door opening accumulated time data stored in the number storage unit 25 and the time storage unit 27 are acquired, and the data is transmitted in step 8. In step 9, the notification unit 31 starts operating and lights during data transmission to notify this.
一方、携帯端末22はステップ10で上記データを受信し、ステップ11においてそのデータを携帯端末22の表示部39に表示する。 On the other hand, the portable terminal 22 receives the data at step 10 and displays the data on the display unit 39 of the portable terminal 22 at step 11.
このようにこの実施の形態における無線通信システムは、対象機器となる冷蔵庫自体に直接携帯端末22を近づけてデータを取得するので、複数の対象冷蔵庫があっても、通信実施時には、必ず対象となる冷蔵庫にタッチする動作で携帯端末を持ち寄ることになるので、子供等であっても対象を誤解することがなく直感的に理解することができ、操作に迷うことなく安心して使用でき、使いやすいとともに、インターネットを介在することなく対象冷蔵庫と携帯端末で直接データを受信するためセキュリティの問題も発生することがなく、安全性も向上する。 As described above, the wireless communication system according to this embodiment acquires data by bringing the portable terminal 22 directly close to the refrigerator itself serving as a target device. Therefore, even when there are a plurality of target refrigerators, the wireless communication system is always a target when performing communication. Because you will bring your mobile device by touching the refrigerator, you can understand it intuitively without misunderstanding the target even if you are a child, etc. Since the data is directly received by the target refrigerator and the portable terminal without using the Internet, the security problem does not occur and the safety is improved.
また、上記した如くこの無線通信システムでは冷蔵庫と無線通信すべく携帯端末22の無線通信用アプリを起動すると、その表示部39に冷蔵庫側無線送受信部21に表記されている図形21bと相似の図形22aが表示されるので、使用者はこの図形22aに基づ
き携帯端末22の携帯端末側無線送受信部33を自然と当該図形22aと相似図形が表示されている部分、すなわち冷蔵庫側無線送受信部21にタッチさせることになり、はじめて使用する時や子供等であっても迷うことなく携帯端末22をタッチさせる場所を認識することができ、使い勝手が向上する。特に前記冷蔵庫側の図形21bと前記携帯端末側に表示する図形22aとは相似形としてあるので、使用者は確実に冷蔵庫側無線送受部の位置を認識できるようになる。
Further, as described above, in this wireless communication system, when the wireless communication application of the portable terminal 22 is activated to wirelessly communicate with the refrigerator, a graphic similar to the graphic 21b written on the refrigerator-side wireless transmission / reception unit 21 is displayed on the display unit 39. Since 22a is displayed, the user can naturally move the portable terminal side wireless transmission / reception unit 33 of the portable terminal 22 to the portion where the similar figure to the figure 22a is displayed, that is, the refrigerator side wireless transmission / reception unit 21 based on the figure 22a. It is possible to recognize the place where the mobile terminal 22 is touched without hesitation even when it is used for the first time or a child or the like, and the usability is improved. In particular, since the graphic 21b on the refrigerator side and the graphic 22a displayed on the portable terminal side are similar, the user can surely recognize the position of the refrigerator-side wireless transmission / reception unit.
加えて、上記携帯端末22の表示部39に表示される図形22aは携帯端末側無線送受信部33の背面となる表示部39の一部分に表示されているから、使用者はこの図形部分を冷蔵庫側無線送受信部21に重ね合わせればよく、送受信操作に間違いや戸惑いを感じることがなく、操作性が向上すると同時に、両者の無線送受信部21b、22aの位置ずれもなくなって、良好な通信性能の確保が可能となる。 In addition, since the graphic 22a displayed on the display unit 39 of the portable terminal 22 is displayed on a part of the display unit 39 on the back of the portable terminal-side wireless transmission / reception unit 33, the user places the graphic part on the refrigerator side. It is only necessary to superimpose on the wireless transmission / reception unit 21, so that there is no feeling of error or confusion in the transmission / reception operation, and the operability is improved. Is possible.
更に、上記携帯端末側無線送受信部33に記載されている図形22aは、冷蔵庫側無線送受信部21の図21a形よりも大きく表示されるように構成してあるから、使用者は冷蔵庫の小さな図形に覆いかぶせるように携帯端末22をタッチさせるようになるので、両者の冷蔵庫側無線送受信部21,33が位置ずれして通信不良を起こすようなことがなくなり、常に良好な通信性能を維持することができる。 Furthermore, since the figure 22a described in the portable terminal side wireless transmission / reception unit 33 is configured to be displayed larger than the shape of the refrigerator side wireless transmission / reception part 21 in FIG. Since the portable terminal 22 is touched so as to be covered, the refrigerator-side wireless transmission / reception units 21 and 33 are not displaced to cause communication failure, and always maintain good communication performance. Can do.
一方、上記した如く冷蔵庫側無線送受信部21に携帯端末側無線送受信部33をタッチさせて携帯端末22がデータ受信を始めると、冷蔵庫の外面に設けた報知部31が動作して点灯し、冷蔵庫側無線送受信部21からデータを送信している間中点灯してこれを使用者に知らせる。よって、使用者は携帯端末22で受信が開始されない時は、例えば携帯端末22と冷蔵庫側無線送受信部21との通信がうまく行われていないというようなことが分かって不安感を持つことがなくなる。また冷蔵庫側無線送受信部21と携帯端末22とが通信を始めてから所定時間後、例えば冷蔵庫側のデータをすべて送信し終えたときには、報知部31が動作を停止、例えば消灯するので、使用者は通信が完了したことを知ることができ、このタイミングで冷蔵庫側無線送受信部21から携帯端末22を離せばよいことが分かり、子供やお年寄りであっても迷うことなくデータ受信を完了することができる。 On the other hand, when the portable terminal 22 starts to receive data by touching the refrigerator-side wireless transceiver unit 21 with the refrigerator-side wireless transceiver unit 21 as described above, the notification unit 31 provided on the outer surface of the refrigerator operates and lights up. Lights during transmission of data from the side wireless transceiver 21 to inform the user. Therefore, when the reception is not started by the mobile terminal 22, the user does not feel uneasy because, for example, it is understood that the communication between the mobile terminal 22 and the refrigerator-side wireless transmission / reception unit 21 is not performed well. . In addition, when a predetermined time has elapsed after the refrigerator-side wireless transmission / reception unit 21 and the portable terminal 22 have started communication, for example, when all the data on the refrigerator side has been transmitted, the notification unit 31 stops its operation, for example, turns off. It is possible to know that the communication has been completed, and at this timing, it can be understood that the portable terminal 22 should be separated from the refrigerator-side wireless transmission / reception unit 21, and even the child or the elderly can complete the data reception without hesitation. it can.
また、携帯端末22の表示部39に扉開閉回数及び扉開成累計時間が表示されるので、使用者は携帯端末22の表示部39をみることによって扉開閉回数等を知ることができ、例えばその回数等が多い時には以降の扉開閉回数を少なくしようと気をつけて節電が促進されることになる。また、冷蔵庫は使用者に扉開閉回数等を知らせるための表示電力を必要とせず、その分更に節電でき、冷蔵庫の省エネルギー化が向上する。すなわち、この冷蔵庫は上記扉開閉回数等を携帯端末22の表示部39を介して知ることができるから、冷蔵庫自体はその扉開閉回数等を表示するための電力を一切消費することがなく、その分省エネルギー化が進むことになる。 In addition, since the door opening / closing count and the door opening accumulated time are displayed on the display unit 39 of the mobile terminal 22, the user can know the door opening / closing frequency by looking at the display unit 39 of the mobile terminal 22, for example, When the number of times is large, power saving is promoted by taking care to reduce the number of times the door is opened and closed thereafter. In addition, the refrigerator does not require display power for notifying the user of the number of times the door is opened and closed, so that power can be further saved, and energy saving of the refrigerator is improved. That is, since the refrigerator can know the number of times of opening and closing the door via the display unit 39 of the portable terminal 22, the refrigerator itself does not consume any power for displaying the number of times of opening and closing the door. Energy saving will be promoted.
さらにこの実施の形態では冷蔵庫側に近接通信検出部29を備えていて当該近接通信検出部29がデータ要求/制御信号送信されていることを検出した場合のみ冷蔵庫側無線送受信部21が誘電してデータを送信するので、冷蔵庫側無線送受信部21が電力を消費することもなく、その分さらなる省エネルギー化が図れる。 Further, in this embodiment, the refrigerator side wireless transmission / reception unit 21 is inducted only when the proximity communication detection unit 29 is provided on the refrigerator side and the proximity communication detection unit 29 detects that the data request / control signal is transmitted. Since the data is transmitted, the refrigerator-side wireless transmission / reception unit 21 does not consume power, and further energy saving can be achieved.
一方、携帯端末22が上記のようにして取得した扉開閉回数及び扉開成累計時間データは使用者が携帯電話と同様インターネット回線を介して所定の場所、例えば省エネサービスセンター等の業者や出勤中の親等に送信することができる。 On the other hand, the number of times the door is opened and closed and the accumulated door opening time data acquired by the mobile terminal 22 as described above are the same as those used for mobile phones by the user through a predetermined location such as an energy-saving service center or a person who is on duty. Can be sent to a parent.
従って、例えば省エネサービスセンター等の業者は携帯端末22から送信されてきた扉
開閉回数及び扉開成累計時間データを見て、携帯端末22に冷蔵庫の制御データ、例えば庫内冷却温度の設定温度データを送信することができる。
Therefore, for example, a company such as an energy saving service center looks at the door opening / closing frequency and door opening accumulated time data transmitted from the mobile terminal 22 and stores control data of the refrigerator, for example, set temperature data of the internal cooling temperature, in the mobile terminal 22. Can be sent.
上記設定温度データを受け取った使用者は再度携帯端末22を冷蔵庫の冷蔵庫側無線送受信部21に近接させ、ステップ12で送信信号を送信すると、冷蔵庫側無線送受信部21が前記と同様にして動作状態となって、ステップ13で制御信号有か否かを確認する。確認の結果、有であると次のステップ14で異常検出部30Aが異常を検出していないかを確認し、異常であれば何もせずにステップ4へと移行するが、異常なしであればステップ15で冷蔵庫の設定温度を携帯端末22から送信されてきた制御データである設定温度データに更新する。 When the user who has received the set temperature data again brings the portable terminal 22 close to the refrigerator-side wireless transmission / reception unit 21 of the refrigerator and transmits a transmission signal in step 12, the refrigerator-side wireless transmission / reception unit 21 operates in the same manner as described above. In step 13, it is confirmed whether or not there is a control signal. As a result of the confirmation, if it is present, it is confirmed in the next step 14 whether the abnormality detection unit 30A has detected an abnormality. If there is an abnormality, the process proceeds to step 4 without doing anything. In step 15, the set temperature of the refrigerator is updated to set temperature data that is control data transmitted from the portable terminal 22.
この設定温度の更新は扉開閉回数及び扉開成累計時間データの状況によって次のようになる。 The update of the set temperature is as follows according to the status of the door opening / closing frequency and the door opening accumulated time data.
すなわち、その一つとしては、扉開閉回数及び扉開成累計時間が多い時の制御データは設定温度を高目とするデータとしてある。これにより、扉開閉回数が多い時は庫内温度が上昇しがちでその都度圧縮機が運転開始し消費電力が多くなりがちであるが、設定温度を高め設定に変更すれば庫内温度が扉開閉によって少々上昇しても圧縮機が運転するのを抑制することができ、電力消費を抑えることができる。 That is, as one example, the control data when the door opening / closing frequency and the door opening cumulative time are large is data for setting the set temperature high. As a result, when the number of times the door is opened and closed, the internal temperature tends to rise and the compressor starts to operate each time, and the power consumption tends to increase. Even if it rises a little by opening and closing, it can suppress that a compressor operates, and can suppress power consumption.
また、扉開閉回数及び扉開成累計時間が少ない時の制御データは設定温度を低目とするデータとしてある。これにより、扉開閉数が多い時とは逆に扉開閉数が少ない時は、庫内温度上昇は少なく低温に維持されているから、少々設定温度を低目にしても圧縮機が運転するようなことはなく、逆にこの間に食品の温度を低目維持しておいて、扉開閉回数が多くなった時、多少庫内温度が上昇しても食品温度は低く保持できるようになり、消費電力を上げることなく良好な食品冷却を維持することができる。 Further, the control data when the door opening / closing frequency and the door opening cumulative time are short are data for setting the set temperature low. As a result, when the number of doors open / closed is small, the internal temperature rise is small and the temperature is kept low when the doors are open / closed. In contrast, when the temperature of the food is kept low during this period, and the number of times the door is opened and closed increases, the food temperature can be kept low even if the temperature inside the chamber rises somewhat, and it is consumed. Good food cooling can be maintained without increasing power.
以上のようにしてこの冷蔵庫は、扉の開閉回数及び開閉累計時間に応じて携帯端末22から制御データを送信し、冷蔵庫自体の運転が低消費電力運転となるように条件変更することができ、携帯端末22の表示部39へ扉開閉回数及び開閉累計時間表示して節電啓蒙した使用者による扉開閉回数低減による節電と合わせて、大きな省エネ効果が期待できる。 As described above, this refrigerator can transmit control data from the portable terminal 22 according to the number of times the door is opened and closed and the total opening and closing time, and the conditions can be changed so that the operation of the refrigerator itself is a low power consumption operation. A large energy saving effect can be expected together with the power saving by reducing the number of times the door is opened and closed by the user who has displayed the number of times the door is opened and closed and the accumulated opening and closing time on the display unit 39 of the portable terminal 22.
またこの実施の形態の冷蔵庫では、扉開閉検出部23からの扉開閉回数あるいは開成時間の前日データを記憶する前日情報記憶部30を備えており、前記前日情報記憶部30からのデータに基づき扉開閉が多くなる時間帯の所定時間前に設定温度を高目とする制御データを制御部32に出力する。これにより、制御部32は設定温度を所定時間前に低目に変更する。 Further, the refrigerator of this embodiment includes a previous day information storage unit 30 for storing the previous day data of the door opening / closing number or opening time from the door opening / closing detection unit 23, and the door is based on the data from the previous day information storage unit 30. Control data for increasing the set temperature is output to the control unit 32 a predetermined time before the time period during which opening and closing increases. As a result, the control unit 32 changes the set temperature to a low level a predetermined time before.
このように、扉開閉が多くなって庫内温度が上昇しやすい時間帯の前に設定温度を下げて庫内温度を低目としておくことにより、扉開閉回数が多くなって庫内温度が少々上昇しても食品に与える影響は微小なものとすることができ、消費電力を上げることなく良好な食費冷却を維持することができる。 In this way, by lowering the set temperature and lowering the internal temperature before the time period when the door open / close increases and the internal temperature tends to rise, the number of door opening / closing increases and the internal temperature decreases slightly. Even if it rises, the effect on food can be made minute, and good food cost cooling can be maintained without increasing power consumption.
更にこの冷蔵庫は冷蔵庫の異常検出部30Aを備えており、前記異常検出部30Aが異常を検出しているとき制御部32は携帯端末から制御データを受信しても前記した如く制御内容の変更を行わない構成としてある。 The refrigerator further includes an abnormality detection unit 30A for the refrigerator. When the abnormality detection unit 30A detects an abnormality, the control unit 32 can change the control contents as described above even if control data is received from the portable terminal. The configuration is not performed.
これにより、冷蔵庫に異常、例えば扉パッキンの損傷により庫内温度が何時まで経っても設定温度に達せず圧縮機が運転状態を続けているような異常時に、扉の開閉が少ないと
いうことで設定温度を低目に変更して圧縮機をより大能力で運転させ続け、電力を無駄に浪費させてしまうような障害発生を未然に防止することができる。
As a result, there is little opening and closing of the door when there is an abnormality in the refrigerator, for example, when the temperature does not reach the set temperature regardless of how long the internal temperature has passed due to damage to the door packing, and the compressor continues to operate It is possible to prevent the occurrence of a failure that wastes electric power by continuously changing the temperature to a low level and keeping the compressor operating at a higher capacity.
なお、この実施の形態の冷蔵庫では上記冷蔵庫側無線送受信部21を冷蔵庫最上位となる貯蔵室2の扉、すなわち、複数ある貯蔵室のうち最上部の扉に設けてあるから、下部に位置する扉に設けた場合のような障害、すなわち、冷蔵庫側無線送受信部21を設けた扉より上の扉を開けた時に漏れ落ちてくる冷気が冷蔵庫側無線送受信部21に触れてその表面に結露が生じ、通信状態の劣化や部品信頼性の低下等の障害を引き起こすことがない。したがって、携帯端末22との間で正確かつ確実に扉開閉回数及び時間のやり取りを行うことができ、品質の高い冷蔵庫とすることができるとともに使用者は安心して使用することができる。 In the refrigerator of this embodiment, the refrigerator-side wireless transmission / reception unit 21 is provided at the top door of the storage room 2, which is the top of the refrigerator, that is, the uppermost door among the plurality of storage rooms, and therefore is positioned at the lower part. Obstacles such as when it is provided on the door, that is, cold air that leaks down when the door above the door provided with the refrigerator-side wireless transmission / reception unit 21 is opened touches the refrigerator-side wireless transmission / reception unit 21 and condensation forms on its surface. Does not cause troubles such as deterioration of communication state and deterioration of component reliability. Therefore, the door opening / closing frequency and time can be exchanged accurately and reliably with the portable terminal 22, and a high-quality refrigerator can be obtained and the user can use it with peace of mind.
また、上記冷蔵庫側無線送受信部21は複数ある貯蔵室のうちの冷蔵室2に対応する扉に設けてあり、この冷蔵室2は製氷室3や冷凍室5よりも庫内温度が高いので庫内冷気による影響を少なく抑えることができる。したがって、冷蔵庫側無線送受信部21の表面と内部の温度差は小さく抑えられ、結露が発生するのを抑制することができ、通信状態の劣化や部品信頼性の低下等の障害を少なくすることができる。 The refrigerator-side wireless transmission / reception unit 21 is provided on a door corresponding to the refrigerator compartment 2 among the plurality of storage rooms, and the refrigerator compartment 2 has a higher internal temperature than the ice making compartment 3 and the freezer compartment 5, so It is possible to reduce the influence of internal cold air. Therefore, the temperature difference between the surface and the inside of the refrigerator-side wireless transmission / reception unit 21 is suppressed to be small, it is possible to suppress the occurrence of dew condensation, and to reduce obstacles such as deterioration of communication state and deterioration of component reliability. it can.
更に、上記冷蔵庫側無線送受信部21は右側扉11bの端部に設けた操作ユニット18に組み込んであり、使用者が日常的に行う扉への掲示物の張りつけがあってもその張りつけは扉中央部分になることが多く、扉端部に位置する冷蔵庫側無線送受信部21の表面を覆ってしまうようなことは少ない。したがって、使用者は直接携帯端末22の冷蔵庫側無線送受信部21に対向接近させることができ、掲示物の上から携帯端末22を近づけることによって生じるデータ送受信ミスが少なくなるとともに、冷蔵庫側無線送受信部21表面にかぶさる掲示物を払いのけて携帯端末を近づけるなどしなくてよく、確実な通信性能確保と使い勝手の向上が可能となる。 Further, the refrigerator-side wireless transmission / reception unit 21 is incorporated in the operation unit 18 provided at the end of the right door 11b, and even if a user sticks a posting to the door on a daily basis, the sticking is performed at the center of the door. It often becomes a part, and it rarely covers the surface of the refrigerator-side wireless transmission / reception unit 21 located at the door end. Therefore, the user can directly face and approach the refrigerator-side wireless transmission / reception unit 21 of the portable terminal 22, and data transmission errors caused by bringing the portable terminal 22 close to the posting are reduced, and the refrigerator-side wireless transmission / reception unit Thus, it is not necessary to dispose of the bulletin board covering the surface 21 and bring the portable terminal closer, and it is possible to ensure reliable communication performance and improve usability.
また、冷蔵庫側無線送受信部21を設けた貯蔵室2の右側扉11bはこれに対応して自動扉開閉機構17を設けてあるから、キッチンで作業している使用者の手が水で濡れていてもこの水による無線送受信部の障害を少なくすることができる。すなわち、使用者は扉に軽くタッチするだけでよくなるため、扉開閉時に扉表面に付着する水滴は極めて微量か付着しない状態となり、冷蔵庫側無線送受信部21に携帯電話等の携帯端末22を接近させるときに、この扉表面に付着した水滴が冷蔵庫側無線送受信部21自体やこの冷蔵庫側無線送受信部21に接近させる携帯端末22に付着して、これを汚したり濡らしたりする不具合を防止することができ、通信状態の劣化や部品信頼性の低下等の障害をより少なくすることができる。 In addition, the right door 11b of the storage room 2 provided with the refrigerator-side wireless transmission / reception unit 21 is provided with an automatic door opening / closing mechanism 17 corresponding thereto, so that the user's hand working in the kitchen is wet with water. However, it is possible to reduce the trouble of the wireless transmission / reception unit due to this water. That is, since the user only needs to touch the door lightly, a very small amount of water droplets adhere to the door surface when the door is opened and closed, and the portable terminal 22 such as a mobile phone is brought close to the refrigerator-side wireless transmission / reception unit 21. Sometimes, water droplets adhering to the door surface adhere to the refrigerator-side wireless transmitter / receiver 21 itself or the portable terminal 22 that is brought close to the refrigerator-side wireless transmitter / receiver 21 to prevent the problem of soiling or getting wet. It is possible to reduce failures such as deterioration of communication state and deterioration of component reliability.

(Embodiment 2)
The second embodiment has the same configuration as that of the first embodiment, but differs from the first embodiment in that steps 4 and 5 of the control flow of the control unit 32 operate as follows.
すなわち、実施の形態2を示す図7のステップ4は、ステップ8で行った前回のデータ送信後、所定時間経過或いはデータ蓄積量が所定量以上に達したかを確認し、所定時間経過或いはデータ蓄積量が所定量以上であれば、ステップ5で報知部31を点滅させるなどして携帯端末22に対しデータ要求動作を行うように要請報知する構成としてある。 That is, in step 4 of FIG. 7 showing the second embodiment, after the previous data transmission performed in step 8, it is confirmed whether the predetermined time has elapsed or the data accumulation amount has reached a predetermined amount or more, and the predetermined time has elapsed or data If the accumulated amount is equal to or larger than the predetermined amount, the notification unit 31 is blinked in step 5 so that the mobile terminal 22 is requested to perform the data request operation.
これによって、この実施の形態では、前回のデータ要求動作した後、長時間、例えば24時間データ要求動作が行われていない、或いはデータ蓄積量が所定以上に達しているということを使用者に知らせて、使用者にデータ要求動作を促したり、逆にデータ蓄積量が少ないので今現在はデータ要求動をする必要がない、或いはデータ要求動作をしても取得
できるデータ量が少ないのでデータ要求動作をしなくてもよいということを知らせることができる。したがって、使用者は携帯端末22によるデータ取得する時期を的確に知ることもできるようになり、何時データ取得しようかと迷うこともなくなって使い勝手が向上する。
As a result, in this embodiment, after the previous data request operation, the user is informed that the data request operation has not been performed for a long time, for example, 24 hours, or the data storage amount has reached a predetermined value or more. The data request operation is urged to the user, and conversely, since the data storage amount is small, there is no need to perform the data request operation at present, or the data amount that can be acquired even if the data request operation is performed, the data request operation You can be informed that you don't have to. Therefore, the user can accurately know when to acquire data by the portable terminal 22, and does not hesitate when to acquire data, improving usability.
(実施の形態3)
図8は実施の形態4を示し、この実施の形態3は扉開閉回数等を表示する表示部43を冷蔵庫本体1の扉11bに設けたもので、情報記憶部28からの扉開閉回数及び扉開成累計時間等の冷蔵庫データ等を冷蔵庫に直接表示するように構成してある。
(Embodiment 3)
FIG. 8 shows a fourth embodiment. In the third embodiment, a display unit 43 for displaying the number of times the door is opened and closed is provided on the door 11b of the refrigerator body 1, and the number of times the door is opened and closed from the information storage unit 28. Refrigerator data such as the cumulative total opening time is displayed directly on the refrigerator.
したがって、この実施の形態3においても先の実施の形態1と同様、使用者はこの表示部43を見ることによって扉開閉回数及び扉開成累計時間を知ることができ、その回数が多い時には以降の扉開閉回数を少なくしようと気をつけて節電が促進されることになる。その他の構成及び動作は実施の形態1と同様であり、説明は割愛する。 Accordingly, also in this third embodiment, as in the first embodiment, the user can know the number of times the door is opened and closed and the total opening time of the door by looking at this display unit 43. Power saving will be promoted by taking care to reduce the number of times the door is opened and closed. Other configurations and operations are the same as those in the first embodiment, and a description thereof will be omitted.
以上のようにこの実施の形態で説明した通信システムと冷蔵庫は、高価な通信機能を付加することなく使用性とセキュリティ安全性の高いインターネット通信ができるうえに、携帯端末と無線通信する冷蔵庫側の無線送受信部の位置が自然と認識できて使い勝手の良いものであるが、上記実施の形態で説明したものは本発明を実現する一形態であり、本発明の目的達成範囲内であれば種々変更可能である。 As described above, the communication system and the refrigerator described in this embodiment can perform Internet communication with high usability and security safety without adding an expensive communication function, and on the refrigerator side that wirelessly communicates with the mobile terminal.
