Description

本発明は人が持っている静電容量値を検出して、電動で解放する扉の誤動作を防ぐ冷蔵庫に関するものである。   The present invention relates to a refrigerator that detects a capacitance value of a person and prevents malfunction of a door that is electrically opened.

近年、高齢化社会を向かえ、家庭内などで使用される機器の使い勝手が重要視されている。特に、大型機器である冷蔵庫においては、近年の大型化指向大容量化の流れに伴って扉も相対的に大型化してきており、その扉の開閉に負担がかかる傾向が無視できなくなってきた。このため、冷蔵庫における扉の開閉を補助し、特に開扉時の負担を軽減することを狙いとした冷蔵庫が提案されている。   In recent years, the importance of the convenience of devices used in homes and the like has been emphasized toward an aging society. In particular, in a refrigerator that is a large-sized device, the door has also become relatively large with the recent trend toward larger-size and larger capacity, and the tendency to place a burden on the opening and closing of the door cannot be ignored. For this reason, the refrigerator which aimed at assisting opening and closing of the door in a refrigerator and reducing especially the burden at the time of door opening is proposed.

従来の冷蔵庫の開扉の方法としては、開扉スイッチを押すと扉背面にある扉開放機構が扉を押し出すものがある（例えば、特許文献１参照）。   As a conventional refrigerator opening method, there is a method in which a door opening mechanism on the back surface of the door pushes out the door when a door opening switch is pressed (for example, see Patent Document 1).

図８は特許文献１に記載された従来の冷蔵庫の正面図を示すものである。図８に示すように、外箱と内箱とこれら内外箱間に断熱材を発泡充填した断熱箱体で形成された冷蔵庫本体１は、内箱内部に貯蔵空間として最上部に冷蔵室２、その下方には野菜室３続いて、断熱仕切壁を介して製氷貯氷室４と温度切替室５とを左右に区分して併置しており、最下部には冷凍室６を独立して配置し、各貯蔵室の前面開口には各々専用の扉を設けて開閉自在に閉塞している。最も大きな収納容量を有する冷蔵室２の開口部前面には、これを開閉すべく冷蔵室扉７が設置されている。   FIG. 8 shows a front view of a conventional refrigerator described in Patent Document 1. In FIG. As shown in FIG. 8, the refrigerator main body 1 formed of an outer box, an inner box, and a heat insulating box body in which a heat insulating material is foam-filled between these inner and outer boxes is a refrigerator compartment 2 at the top as a storage space inside the inner box, Below that, the vegetable compartment 3 is followed by an ice-making storage room 4 and a temperature switching room 5 separated from each other through a heat-insulating partition wall, and a freezing room 6 is arranged independently at the bottom. The front opening of each storage chamber is provided with a dedicated door and is closed so as to be freely opened and closed. In front of the opening of the refrigerating room 2 having the largest storage capacity, a refrigerating room door 7 is installed to open and close the opening.

また、冷蔵庫本体１の上面には扉開放ユニット８が、冷蔵室扉７の前面には開扉スイッチ９がそれぞれ設置されている。   A door opening unit 8 is installed on the upper surface of the refrigerator body 1, and an opening switch 9 is installed on the front surface of the refrigerator compartment door 7.

以上のように構成された冷蔵庫について、以下その動作を説明する。   About the refrigerator comprised as mentioned above, the operation | movement is demonstrated below.

まず、冷蔵室扉７を開扉するために開扉スイッチ９が押されると、開扉信号が扉開放ユニット８に送られる。次に扉開放ユニット８ではこの信号を受けて、冷蔵室扉７を背面から押出す動作を開始させる。動作の具体例としては、モータやソレノイドなどのアクチュエータを使用して、連接されたピストンピンなどを直線移動させて、その押圧によって冷蔵室扉７を開扉させる。   First, when the door opening switch 9 is pressed to open the refrigerator compartment door 7, a door opening signal is sent to the door opening unit 8. Next, the door opening unit 8 receives this signal and starts the operation of pushing out the refrigerator compartment door 7 from the back surface. As a specific example of the operation, an actuator such as a motor or a solenoid is used to linearly move a connected piston pin or the like, and the refrigerator compartment door 7 is opened by the pressing.

これらにより、開扉時のこれまでの扉を持ち、初動時に大きな力が必要となる負担をなくすことができ、開扉スイッチ９を押すというわずかな負担で簡単に開扉ができるようになる。
特開２００３−２６２４５６号公報 As a result, it is possible to eliminate the burden of requiring a large force at the time of initial movement by having the doors at the time of opening, and to easily open the door with a slight burden of pushing the door opening switch 9.
JP 2003-262456 A

しかしながら、上記従来の構成では、開扉スイッチ９を押すという簡単な操作であるため、使用者以外の例えば子供やペット等が誤って開扉スイッチ９に触れて開扉信号は発生する可能性が高く、安全面が確保できないという課題を有していた。   However, in the above conventional configuration, since it is a simple operation of pressing the door opening switch 9, there is a possibility that a door opening signal is generated when a person other than the user, for example, a child or a pet accidentally touches the door opening switch 9. It was expensive and had a problem that safety could not be secured.

本発明は、上記従来の課題を解決するもので、開扉時の操作における誤動作を防止することができる冷蔵庫を提供することを目的とする。   This invention solves the said conventional subject, and it aims at providing the refrigerator which can prevent the malfunctioning in the operation at the time of door opening.

Only when a person approaches, the detection means is operated to make a determination, and the door is opened.

本発明の冷蔵庫は、人が近づいた場合にのみ検出手段を動作させるので、人が触れる場合以外の外的な静電容量値の変化で解放手段が動作することはなく、誤動作を防止することができる。   Since the refrigerator of the present invention operates the detection means only when a person approaches, the release means does not operate due to an external change in capacitance value other than when a person touches, and prevents malfunction. Can do.

また、本発明の冷蔵庫は、開扉時には解放手段を動作させないので、自扉と解放手段との衝突による破壊がなくせ、信頼性の高い機構が提供できる。   In addition, since the refrigerator of the present invention does not operate the release means when the door is opened, it is possible to eliminate the damage caused by the collision between the door and the release means, and to provide a highly reliable mechanism.

FIG. 1 is a front view of the refrigerator according to Embodiment 1 of the present invention. FIG. 2 is a side view when the refrigerator door of the refrigerator according to the embodiment is slightly opened. FIG. 3 is an operation flowchart of the refrigerator according to the embodiment.

図１、図２において、冷蔵庫本体１０は、仕切り部１１によって最上部に冷蔵室１２、その下方には野菜室１３、さらにその下方に製氷貯氷室１４と温度切替室１５とを左右に区分して併置しており、最下部には冷凍室１６を形成している。冷蔵室１２の開口部前面には、これを開閉する冷蔵室扉１７がヒンジ（図示せず）で支持され、ヒンジを中心に回転するように取付けられている。さらに、冷蔵室１２、野菜室１３、製氷貯氷室１４、温度切替室１５の開口部前面には、これらを開閉するスライド扉１８が設置されている。   1 and 2, the refrigerator main body 10 is divided into a left and right compartments by a partitioning portion 11, a refrigerator compartment 12 at the top, a vegetable compartment 13 below it, and an ice making storage compartment 14 and a temperature switching compartment 15 below it. The freezer compartment 16 is formed in the lowermost part. On the front face of the opening of the refrigerator compartment 12, a refrigerator compartment door 17 for opening and closing the door is supported by a hinge (not shown) and attached so as to rotate around the hinge. Further, a slide door 18 is provided in front of the opening of the refrigerator compartment 12, the vegetable compartment 13, the ice making storage compartment 14, and the temperature switching compartment 15 to open and close them.

また、人の手が触れた時の人体の静電容量の大きさを検知する検出手段１９は、冷蔵室扉１７の前面の左方（図１のＡ部）、人が近づいたことを検知する人体検知手段２０は、冷蔵室扉１７の前面の右方（図１のＢ部）にそれぞれ配設されている。   Moreover, the detection means 19 which detects the magnitude | size of the electrostatic capacitance of the human body when a person's hand touches detects that the person approached the left side (A section of FIG. 1) of the front surface of the refrigerator compartment door 17. The human body detecting means 20 is disposed on the right side of the front surface of the refrigerator compartment door 17 (B portion in FIG. 1).

また、冷蔵室１２の上部の仕切り部１１内には解放手段２１があり、解放手段２１のロッド部２１ａが直線移動し、冷蔵室扉１７を押出すことができる位置に設置されている。   In addition, the release means 21 is provided in the partition 11 at the upper part of the refrigerator compartment 12, and the rod portion 21 a of the release means 21 is linearly moved so that the refrigerator compartment door 17 can be pushed out.

尚、検出手段１９及び人体検知手段２０はそれぞれ図１のＡ部及びＢ部に配設したが、検出手段１９は操作し易い、また人体検知手段２０は検知し易い任意の場所に配設してもよい。   Although the detection means 19 and the human body detection means 20 are disposed in the A part and the B part of FIG. 1, respectively, the detection means 19 is easy to operate, and the human body detection means 20 is disposed in any place where it is easy to detect. May be.

以上のように構成された冷蔵庫について、以下その動作を図３を用いて説明する。   About the refrigerator comprised as mentioned above, the operation | movement is demonstrated using FIG. 3 below.

まず、ステップ１で制御が開始されると、ステップ２で解放手段２１を停止させる。次にステップ３で人体検知手段２０により冷蔵庫の前に人が近づいているかを検知し、近づいていればステップ４へ論理を進め、近づいていなければステップ３を繰り返す。   First, when control is started in step 1, the release means 21 is stopped in step 2. Next, at step 3, the human body detecting means 20 detects whether a person is approaching the refrigerator. If it is approaching, the logic advances to step 4. If it is not approaching, step 3 is repeated.

次にステップ４では検出手段１９で検出した静電容量が、予め設定したしきい値Ｃ０よりも大きければ人が触れたと判断しステップ６へ論理を進め、否であればステップ３へ論理を戻す。 Next capacitance detected in step 4, the detection means 19, advances the logic to stepping 6 determines that if a person touches greater than threshold value C 0 has been set in advance, the logic to step 3 if not return.

最後にステップ５では検出手段１９から開扉信号を解放手段２１が受取る。解放手段２１にはモータやアクチュエータ（図示せず）などが内蔵されており、連接されたロッド部２１ａを冷蔵室扉１７側へ当接直線移動させ、冷蔵室扉１７を解放させる。開扉後はすばやくロッド部２１ａを解放手段２１内に格納させ、論理をステップ２に戻す。   Finally, in step 5, the opening means 21 receives the door opening signal from the detection means 19. The release means 21 incorporates a motor, an actuator (not shown), etc., and moves the connected rod portion 21a to the refrigerating room door 17 side to move linearly, thereby releasing the refrigerating room door 17. After opening the door, the rod portion 21a is quickly stored in the release means 21, and the logic is returned to step 2.

以上のように、本実施の形態においては、冷蔵庫本体内を複数の貯蔵室に区画する仕切り部と、前記貯蔵室の開口部を開閉する複数の扉を有し、前記扉の手が触れる部分に設置した人体の静電容量を検知する検出手段と、人が近づいたことを検知する人体検知手段と、前記扉を解放する解放手段を備えたことにより、人体検知手段で人が近づいた場合のみに、検出手段で静電容量を検知するので、人以外の静電容量による誤動作をなくすことができ、確実で信頼性の高い人が触れた検知を行なうことが可能になる。   As mentioned above, in this Embodiment, it has a partition part which divides the inside of a refrigerator main part into a plurality of store rooms, and a plurality of doors which open and close the opening of the store room, and a part which the hand of the door touches When the human body detection means approaches the human body detection means by detecting the electrostatic capacity of the human body installed in the human body detection means, the human body detection means for detecting the approach of the person, and the release means for releasing the door In addition, since the electrostatic capacity is detected by the detection means, it is possible to eliminate malfunctions due to electrostatic capacity other than that of humans, and it is possible to perform detection with reliable and reliable human touch.

また、本実施の形態の人体検知手段を検出手段よりも小さな静電容量を検知する静電容量型センサとすることにより、人が近づいてきた時には人体の持っている静電容量値よりも小さな値を、空気を介して検知するので、人体検知手段と検出手段を同一構成の静電容量検出処理回路で行なうことができ、回路の簡素化と低コスト化を図ることができる。   In addition, the human body detection means of the present embodiment is a capacitance type sensor that detects a smaller electrostatic capacity than the detection means, so that it is smaller than the capacitance value of the human body when a person approaches. Since the value is detected through air, the human body detection means and the detection means can be performed by the electrostatic capacity detection processing circuit having the same configuration, and the circuit can be simplified and the cost can be reduced.

また、本実施の形態の人体検知手段を焦電型赤外線センサとすることにより、センサは広範囲で人の体温の動きを検知するので、冷蔵庫から遠く離れた場所から人が近づいてきていることが早い段階で判り、検出手段が検知する待機モードが確実に設定できるので、人が触れたことが素早く検知できる。   Moreover, since the human body detecting means of the present embodiment is a pyroelectric infrared sensor, the sensor detects the movement of the human body temperature in a wide range, so that the person is approaching from a place far away from the refrigerator. Since the standby mode that can be detected at an early stage and detected by the detection means can be set reliably, it is possible to quickly detect that a person has touched.

また、本実施の形態の人体検知手段を反射型赤外線センサとすることにより、センサは赤外線を発光して人に反射して帰ってくるまでの時間で、冷蔵庫と人との距離を検知するので、検知エリア内に人がきたことが確実にわかり、温度、湿度などの環境要因による人体検知の誤検知を防止することができ、信頼性の高い検出手段を達成することができる。   In addition, by making the human body detection means of this embodiment a reflective infrared sensor, the sensor detects the distance between the refrigerator and the person in the time it takes to emit infrared light and reflect it back to the person. Therefore, it is possible to surely know that a person has come into the detection area, prevent erroneous detection of human body detection due to environmental factors such as temperature and humidity, and achieve highly reliable detection means.

また、本実施の形態の人体検知手段を照度センサとすることにより、センサは人が近づいて室内照明とセンサの間に入った場合に検出照度が暗くなることを検知するので、照度によって人体を検知することができ、デレビや携帯電話などで一般的に使用される汎用で安価なセンサを使用することができる。   In addition, by making the human body detecting means of the present embodiment an illuminance sensor, the sensor detects that the detected illuminance becomes dark when a person approaches and enters between the room illumination and the sensor. It is possible to use a general-purpose and inexpensive sensor that can be detected and is generally used in a television or a mobile phone.

なお、本実施の形態の検出手段１９は、人が触れた場合の静電容量を検知する静電容量型センサとしたが、人が押した外力の大きさを検知する圧電センサを用いた場合には、人が指等でセンサ部分を押圧することで確実な操作感が得られ検知手段の操作性を向上させることができる。   The detection means 19 of the present embodiment is a capacitance type sensor that detects the capacitance when touched by a person, but a piezoelectric sensor that detects the magnitude of an external force pressed by a person is used. In this case, when a person presses the sensor portion with a finger or the like, a reliable operational feeling can be obtained and the operability of the detecting means can be improved.

（実施の形態２）
図４は、本発明の実施の形態２における冷蔵庫の主要構成ブロック図である。図５は、同実施の形態の冷蔵庫の検出手段が検知する静電容量値のレベル特性図である。 (Embodiment 2)
FIG. 4 is a main configuration block diagram of the refrigerator in the second embodiment of the present invention. FIG. 5 is a level characteristic diagram of the capacitance value detected by the detection means of the refrigerator according to the embodiment.

実施の形態１と同一構成については、同一符号を付してその詳細な説明は省略する。   About the same structure as Embodiment 1, the same code | symbol is attached | subjected and the detailed description is abbreviate | omitted.

図４において、第一の判定手段２２は、人体検知手段２０から人が近づいて冷蔵庫の前にいるか否かの信号Ｓ１と、検出手段１９が検知した人体の静電容量値を信号Ｓ２として入力し、冷蔵庫扉１７を開扉するか否か判断し、判定信号Ｓ３を解放手段２１に出力する。   In FIG. 4, the first determination means 22 inputs a signal S1 indicating whether or not a person is approaching from the human body detection means 20 and is in front of the refrigerator, and a capacitance value of the human body detected by the detection means 19 as a signal S2. Then, it is determined whether or not the refrigerator door 17 is to be opened, and a determination signal S3 is output to the release means 21.

ここで、具体的に第一の判定手段２２が判定する静電容量値のレベルについて説明する。図５は人体が持っている静電容量値を、我々が実験的に確認したレベル特性図である。大まかな区分として、体格の良い男性の指が２００ｐＦ、通常の人差し指が１００ｐＦ、小柄な女性の小指が８０ｐＦ、幼児の指が５０ｐＦのそれぞれ静電容量値を持っていることが判った。   Here, the level of the capacitance value determined by the first determination unit 22 will be specifically described. FIG. 5 is a level characteristic diagram in which we have experimentally confirmed the capacitance value of the human body. As a general classification, it was found that male fingers with good physique have capacitance values of 200 pF, normal index fingers of 100 pF, small female little fingers of 80 pF, and infant fingers of 50 pF.

従って、図５に示す様に基準静電容量Ｃ１を例えば６５ｐＦに設定して、検出手段１９が検知した人体の静電容量値がＣ１以上のときは大人が触れたと判断し開扉させ、Ｃ１以下のときは幼児が触れたと判断し開扉させない。 Therefore, by setting the reference capacitance C 1, for example, 65pF, as shown in FIG. 5, to the door opening is determined that an adult has touched when the electrostatic capacitance value of the human body detecting means 19 detects that the C 1 or more , when the C 1 or less does not door opening is determined that the infant has touched.

図６において、扉の開閉状態を検知する扉スイッチ２３は、一般に磁気センサやプッシュ式接点スイッチなどが使用され、庫内ランプ（図示せず）と連動したもので、例えば閉扉時はスイッチＯＮ、開扉時はスイッチＯＦＦの信号Ｓ４を出力する。第二の判定手段２４はこの扉スイッチ２３からの信号Ｓ４と、検出手段１９からの信号Ｓ５を入力とし、冷蔵庫扉１７を開扉するか否か判断し、判定信号Ｓ６を解放手段２１に出力する。   In FIG. 6, a door switch 23 for detecting the open / closed state of the door generally uses a magnetic sensor, a push-type contact switch or the like, and is interlocked with an interior lamp (not shown). For example, when the door is closed, the switch is ON. When the door is opened, a switch OFF signal S4 is output. The second determination means 24 receives the signal S4 from the door switch 23 and the signal S5 from the detection means 19, determines whether to open the refrigerator door 17, and outputs a determination signal S6 to the release means 21. To do.

尚、図６の点線で示す様に、検出手段１９からの信号を一旦、第一の判定手段２２に入力して、その第一の判定手段２２からの出力信号を、第二の判定手段２４に入力してもよい。   As indicated by the dotted line in FIG. 6, the signal from the detection means 19 is temporarily input to the first determination means 22, and the output signal from the first determination means 22 is converted to the second determination means 24. May be entered.

以上のように構成された冷蔵庫について、以下その動作を図７を用いて説明する。   About the refrigerator comprised as mentioned above, the operation | movement is demonstrated using FIG. 7 below.

まず、ステップ６で制御が開始されると、ステップ７で解放手段２１を停止させる。次にステップ８で扉スイッチ２３により冷蔵庫扉１７の開閉状態を検知し、閉扉であればステップ９へ論理を進め、開扉であればステップ８を繰り返す。   First, when control is started in step 6, the release means 21 is stopped in step 7. Next, in step 8, the open / close state of the refrigerator door 17 is detected by the door switch 23. If the door is closed, the logic advances to step 9. If the door is opened, step 8 is repeated.

次にステップ９で人体検知手段２０により冷蔵庫の前に人が近づいているかを検知し、近づいていればステップ１０へ論理を進め、近づいていなければステップ８へ論理を戻す。   Next, in step 9, the human body detecting means 20 detects whether a person is approaching the refrigerator. If it is approaching, the logic proceeds to step 10, and if not, the logic is returned to step 8.

次にステップ１０では検出手段１９で検出した静電容量が、予め設定したしきい値Ｃ０よりも大きければ人が触れたと判断しステップ１１へ論理を進め、否であればステップ８へ論理を戻す。またこの時、しきい値Ｃ０を実施の形態３で説明した基準静電容量Ｃ１と同値とすれば、幼児が触れた場合には開扉させないことができる。 Next capacitance detected by the detection means 19 in step 10, advances the logic to step 11 determines that if a person touches greater than threshold value C 0 has been set in advance, the logic to step 8 if not return. At this time, if the threshold value C 0 is set to the same value as the reference capacitance C 1 described in the third embodiment, the door cannot be opened when an infant touches it.

最後にステップ１１では第二の判定手段２４から開扉信号を解放手段２１が受取り、解放動作を行い冷蔵庫扉１７を開扉させ、すばやくロッド部２１ａを収納して動作を停止させ、論理をステップ７に戻す。   Finally, in step 11, the opening means 21 receives the opening signal from the second determination means 24, performs the releasing operation, opens the refrigerator door 17, quickly stores the rod portion 21a, stops the operation, and performs the logic step. Return to 7.

以上のように、本実施の形態においては、扉が開放されている状態を検知する扉スイッチと、前記検出手段からの信号と前記扉スイッチからの信号を入力とし、前記解放手段の動作を制御する第二の判定手段を備えたことにより、扉スイッチ２３と検出手段１９からの信号を第二の判定手段２４に入力して、開扉時には検出信号の信号を受付けなくするので、開扉状態で解放手段２１は動作せず、冷蔵庫扉１７と解放手段２１のロッド部２１ａが衝突することはなく、品質的な問題の発生をなくすことができる。   As described above, in the present embodiment, the door switch for detecting the state in which the door is opened, the signal from the detection means, and the signal from the door switch are input to control the operation of the release means. Since the second determination means is provided, the signals from the door switch 23 and the detection means 19 are input to the second determination means 24, and the detection signal is not accepted when the door is opened. Thus, the release means 21 does not operate, the refrigerator door 17 and the rod portion 21a of the release means 21 do not collide, and the occurrence of quality problems can be eliminated.

以上のように、本発明にかかる冷蔵庫は、家庭用又は業務用冷蔵庫に対して実施することができ、大型であるか小型であるかを問わず、全ての冷蔵庫に適用できる。   As described above, the refrigerator according to the present invention can be implemented for household or commercial refrigerators, and can be applied to all refrigerators regardless of whether they are large or small.
