Description

冷蔵庫refrigerator
　本発明は、離氷モータにより製氷皿から氷を取り出す離氷動作時に、製氷皿の位置の誤検知を防止する製氷装置を備える冷蔵庫に関するものである。 The present invention relates to a refrigerator provided with an ice making device that prevents erroneous detection of the position of the ice making tray during the ice removing operation of taking out ice from the ice making tray by an ice removing motor.
　従来、製氷装置を搭載した冷蔵庫は、製氷皿から氷を取り出す離氷動作時に貯氷箱に氷があるか否かの満氷検知を行うが、製氷皿の位置を誤検知した場合、製氷皿が所定の水平位置で停止できない（例えば、特許文献１参照）。 Conventionally, a refrigerator equipped with an ice making device performs full ice detection to determine whether or not there is ice in the ice storage box when the ice is removed from the ice tray, but if the ice tray is misdetected, It cannot be stopped at a predetermined horizontal position (see, for example, Patent Document 1).
中国特許出願公開第１６２９５７１号明細書Chinese Patent Application No. 1629571
　しかしながら、前記従来の構成では、離氷動作時に製氷皿の位置検知を誤検知すると、製氷皿が所定の位置で停止できなくなり、製氷皿が斜めに停止することとなる。この場合は、製氷皿が水平位置であるとの誤検知により、製氷皿に水を給水してしまうこととなる。このままの状態で製氷を行うと所定の大きさの氷ができず、また氷を貯めている貯氷箱にも水が流れ込み、貯めている氷を溶かすことになる。従って、使用者に提供する氷の大きさなどの品位を大きく損なうという課題を有していた。 However, in the conventional configuration, if the position detection of the ice tray is erroneously detected during the ice removing operation, the ice tray cannot be stopped at a predetermined position, and the ice tray is stopped obliquely. In this case, water is supplied to the ice tray due to erroneous detection that the ice tray is in the horizontal position. If ice making is performed in this state, ice of a predetermined size cannot be formed, and water also flows into the ice storage box storing ice, and the stored ice is melted. Therefore, there is a problem that the quality such as the size of ice provided to the user is greatly impaired.
　本発明は、前記従来の課題を解決するもので、所定の大きさの氷ができ、また氷を貯めている貯氷箱への水が流れ込みもなく、貯めている氷を溶かすことがない、使用者に対して高品位の氷を提供することを目的とする。 The present invention solves the above-mentioned conventional problems, and can be used in which ice of a predetermined size is formed, water does not flow into an ice storage box storing ice, and the stored ice is not melted. The purpose is to provide high-quality ice to the people.
　前記従来の課題を解決するために、本願発明にかかる冷蔵庫は、所定の水量の水が注水される製氷皿と、前記製氷皿の水が氷に凝固したら、前記製氷皿を回転し、氷を離氷する離氷モータと、前記製氷皿から離氷した氷を貯めておく貯氷箱と、前記離氷モータの回転位置を検知し、かつ、前記貯氷箱に氷が満氷かを検知する位置検知手段とを備える冷蔵庫であって、前記離氷モータの正転時に前記貯氷箱が満氷と前記位置検知手段が検知し、前記離氷モータの逆転時に所定の時間前記位置検知手段の信号に基づき制御を行わない制御装置を備えることを特徴とする。 In order to solve the above-described conventional problems, the refrigerator according to the present invention includes an ice making tray into which a predetermined amount of water is poured, and when the water in the ice making tray solidifies into ice, the ice making tray is rotated to remove ice. A de-icing motor for de-icing, an ice storage box for storing ice de-iced from the ice tray, a position for detecting the rotational position of the de-icing motor and detecting whether the ice is full in the ice storage box A refrigerator having a detection means, wherein the ice storage box detects full ice and the position detection means when the ice-ice motor is rotating forward, and the position detection means outputs a signal for a predetermined time when the ice-ice motor is reverse. It is characterized by including a control device that does not perform control based on the above.
　本構成によって、離氷モータが正転時に、位置検知手段にて貯氷箱が満氷と検知した場合、離氷モータが逆転となり、位置か満氷の誤検知を防止のため所定の時間位置検知手段を検知しないため、位置検知手段が誤検知しても、製氷皿が斜めで停止することなく、確実に製氷皿を水平位置に動作できる。 With this configuration, when the ice motor is rotating forward, if the position detection means detects that the ice storage box is full, the ice motor will reverse and detect the position for a predetermined time to prevent false detection of the position or full ice. Since the means is not detected, the ice tray can be reliably moved to the horizontal position without stopping the ice tray obliquely even if the position detection means detects it erroneously.
　また、前記制御装置は、前記離氷モータの正転時に前記貯氷箱が満氷と前記位置検知手段が検知した場合、前記離氷モータが逆転となり前記製氷皿を所定の位置まで動作させた時に、前記位置検知手段の信号が所定の値でない場合、再度前記製氷皿を水平にする動作を行うよう制御してもよい。 Further, when the ice storage box detects that the ice storage box is full and the position detection means detects that the ice-breaking motor is rotating in the normal direction, the control device reversely rotates the ice-breaking motor and moves the ice tray to a predetermined position. If the signal from the position detection means is not a predetermined value, the operation may be controlled so that the ice tray is again leveled.
　本構成によって、離氷モータが正転時に、位置検知手段にて貯氷箱が満氷と検知した場合、離氷モータが逆転となり、位置か満氷の誤検知により、製氷皿が斜めに停止した場合は、再度製氷皿を水平の位置に戻す初期化動作を行うことができる。 With this configuration, if the ice storage box detects that the ice storage box is full when the ice-ice motor is rotating forward, the ice-breaking motor will reverse and the ice tray will stop diagonally due to a false detection of the position or full ice. In this case, an initialization operation can be performed to return the ice tray to the horizontal position again.
　本発明の冷蔵庫は、離氷モータが正転時に、位置検知手段によって貯氷箱が満氷と検知された場合、離氷モータが逆転となり、満氷の誤検知を防止のため所定の時間位置検知手段が検知しない状態となるため、位置検知手段が誤検知しても、製氷皿が斜めで停止することなく、確実に製氷皿を水平位置に動作できる。また、離氷モータが正転時に、位置検知手段にて貯氷箱が満氷と検知した場合、離氷モータが逆転となり、位置か満氷の誤検知により、製氷皿が斜めに停止した場合は、再度製氷皿を水平の位置に戻す初期化動作を行うことができるため、所定の大きさの氷ができ、また氷を貯めている貯氷箱への水が流れ込みもなく、貯めている氷を溶かすことがない。従って、使用者に対して常に高品位の氷を提供することができる。 In the refrigerator of the present invention, if the ice storage box is detected to be full ice by the position detection means when the ice removal motor is rotating forward, the ice removal motor is reversed and position detection is performed for a predetermined time to prevent erroneous detection of full ice. Since the means is not detected, the ice tray can be reliably moved to the horizontal position without stopping the ice tray obliquely even if the position detection means detects erroneously. Also, if the ice detection box detects that the ice storage box is full when the ice-breaking motor is running forward, the ice-breaking motor will reverse and if the ice tray stops diagonally due to a false detection of the position or full ice. Because the initialization operation can be performed again to return the ice tray to the horizontal position, ice of a predetermined size can be formed, and water stored in the ice storage box where ice is stored does not flow, so that the stored ice can be removed. There is no melting. Therefore, it is possible to always provide high quality ice to the user.

　第一の発明は、冷蔵庫本体と、冷蔵庫庫内の前面に設けられたドアと、氷を自動で製氷する製氷機と、製氷機で生成した氷を貯めておく貯氷箱と、前記貯氷箱に貯まった氷を排出する排出機で構成された製氷装置において、前記製氷機の水を受ける製氷皿と、前記製氷皿を回転させる離氷モータと、前記離氷モータの回転位置を検知することと前記貯氷箱に氷が満氷かを検知する位置検知手段にて構成した製氷機において、前記離氷モータが正転時に前記貯氷箱が満氷と検知し、前記離氷モータの逆転時に所定の時間前記位置検知手段の信号を検知しない。 The first invention includes a refrigerator main body, a door provided on a front surface in the refrigerator cabinet, an ice making machine that automatically makes ice, an ice storage box that stores ice generated by the ice making machine, and the ice storage box In an ice making device constituted by a discharge machine for discharging stored ice, an ice making tray that receives water from the ice making machine, an ice removing motor that rotates the ice making plate, and a rotation position of the ice removing motor; In the ice making machine configured with position detecting means for detecting whether the ice is full in the ice storage box, the ice storage motor detects that the ice storage box is full when the ice-breaking motor is rotating forward, and a predetermined time is detected when the ice-removing motor is reversely rotated. Time The position detection means signal is not detected.
　このため、前記離氷モータが正転時に、前記位置検知手段にて前記貯氷箱が満氷と検知した場合、前記離氷モータが逆転となり、位置か満氷の誤検知を防止のため所定の時間前記位置検知手段を検知しないため、前記位置検知手段が誤検知しても、製氷皿が斜めで停止することなく、確実に前記製氷皿を水平位置に動作できる。 For this reason, when the ice-breaking motor is rotating forward, if the ice storage box detects that the ice storage box is full by the position detection means, the ice-removing motor is reversely rotated to prevent predetermined detection of the position or full ice. Since the position detection means is not detected for a time, even if the position detection means detects erroneously, the ice tray can be reliably moved to the horizontal position without stopping obliquely.
　第二の発明は、前記離氷モータが正転時に前記貯氷箱が満氷と検知した場合、前記離氷モータが逆転となり前記製氷皿を所定の位置まで動作させた時に、前記位置検知手段の信号が所定の値でない場合、再度前記製氷皿を水平にする動作を行う。 According to a second aspect of the present invention, when the ice storage box detects that the ice storage box is full when the ice removing motor is rotating forward, the position detecting means is operated when the ice removing motor is reversed and the ice tray is moved to a predetermined position. If the signal is not a predetermined value, the ice tray is leveled again.

　図３は、本発明の実施例１における冷蔵庫の製氷機の制御ブロック図である。 FIG. 3 is a control block diagram of the refrigerator ice making machine according to the first embodiment of the present invention.
　図３において、制御装置１６は、前記位置検知手段６と接続されており、前記製氷皿１０の位置、前記貯氷箱９に氷が満氷かを検知することができる。 3, the control device 16 is connected to the position detection means 6 and can detect the position of the ice tray 10 and whether the ice storage box 9 is full of ice.
　また前記制御装置１６は、前記製氷皿１０の水が氷に凝固する温度（冷凍室温度で判断する）なったら、前記制御装置１６から前記モータ駆動手段１８を介して前記離氷モータ１１を正転動作させ、前記製氷皿１０の氷を剥がし落とす、その後、水平位置まで逆転動作を行う。 Further, when the temperature at which the water in the ice tray 10 is solidified into ice (determined based on the freezer temperature), the control device 16 controls the ice removal motor 11 from the control device 16 via the motor driving means 18. Rolling is performed to peel off the ice from the ice tray 10, and then the reverse operation is performed to the horizontal position.

　図４の本発明の実施の形態における冷蔵庫の製氷機の制御タイミングチャートにより動作の説明を行う。 The operation will be described with reference to a control timing chart of the refrigerator ice maker in the embodiment of the present invention shown in FIG.
　前記離氷モータ１１の動作と、位置検知手段６の信号との関係を図４の位置番号を用いて説明する。位置検知手段６は、前記離氷モータ１１に組み込まれていおり、前記製氷皿１０の位置と前記貯氷箱９が満氷の状態で、信号が変化する。 The relationship between the operation of the deicing motor 11 and the signal of the position detection means 6 will be described using the position numbers in FIG. The position detecting means 6 is incorporated in the ice removing motor 11, and the signal changes when the position of the ice tray 10 and the ice storage box 9 are full of ice.
　図４において、位置番号（１）は、前記製氷皿１０が水平の位置にあり、位置検知手段６の信号は、「Ｈ」を示している。 4, the position number (1) indicates that the ice tray 10 is in a horizontal position, and the signal of the position detecting means 6 indicates “H”.
　製氷皿１０内の水が氷になったら、離氷モータ１１は、モータ駆動手段１８を介して、制御装置１６から正転動作する信号が送られ、製氷皿１０は正転動作を開始し、ｔ１４後に前記位置検知手段６の信号は「Ｌ」になる。 When the water in the ice tray 10 becomes ice, the ice removing motor 11 receives a signal for normal rotation operation from the control device 16 via the motor driving means 18, and the ice tray 10 starts normal rotation operation. After t14, the signal of the position detecting means 6 becomes “L”.
　貯氷箱９内の氷が満氷でなかったら、位置検知手段６の信号は「Ｌ」を維持したまま、位置番号（３）を通過し、位置番号（２）にて、位置検知手段６の信号が「Ｌ→Ｈ」に変化し、正転動作は停止する。前記製氷皿１０は、１８０度の離氷の状態となり、前記製氷皿１０の氷が、前記貯氷箱９内に氷が落下する。 If the ice in the ice storage box 9 is not full, the signal of the position detection means 6 passes the position number (3) while maintaining “L”, and at the position number (2), the position detection means 6 The signal changes from “L → H” and the forward rotation operation stops. The ice tray 10 is in an ice-free state of 180 degrees, and the ice in the ice tray 10 falls into the ice storage box 9.
　その後、前記制御装置１６から逆回転の動作を指示され、前記離氷モータ１１が逆転動作になった時に、前記位置検知手段６の信号は、「Ｈ→Ｌ」に変化する。 Thereafter, when a reverse rotation operation is instructed from the control device 16 and the deicing motor 11 is rotated in the reverse direction, the signal of the position detecting means 6 changes from “H → L”.
　前記位置検知手段６の信号が、再び「Ｌ→Ｈ」に変化するまで前記離氷モータ１１は逆転動作を維持し、「Ｌ→Ｈ」に変化したら、前記離氷モータ１１はｔ１２以内に停止する。また、前記製氷皿１０は水平位置に戻る。 The deicing motor 11 maintains the reverse rotation operation until the signal of the position detection means 6 changes from “L → H” again. When the signal changes from “L → H”, the deicing motor 11 stops within t12. To do. The ice tray 10 returns to the horizontal position.
　次に前記貯氷箱９に氷が満氷の時の動作を説明する。 Next, the operation when the ice storage box 9 is full of ice will be described.
　前記製氷皿１０内の水が氷になったら、前記離氷モータ１１は、前記制御装置１６からの前記モータ駆動手段１８を介して、正転動作する信号が送られ、前記製氷皿１０は正転動作を開始し、ｔ１４後に前記位置検知手段６の信号は「Ｌ」になる。 When the water in the ice tray 10 becomes ice, the ice removing motor 11 is sent a signal for normal rotation via the motor driving means 18 from the control device 16, and the ice tray 10 is The rolling operation is started, and after t14, the signal of the position detecting means 6 becomes “L”.
　前記離氷モータ１１が、位置番号（３）でｔ２１以内に前記位置検知手段６の信号が「Ｌ→Ｈ」に変化したら、前記検氷レバー１２が、前記貯氷箱９内の氷が満氷と検知したこととなるため、前記製氷皿の氷を離氷することなく、前記製氷皿を水平位置にする。このため、前記制御装置１６により逆転動作に切り替わり、前記位置検知手段６の信号が「Ｌ→Ｈ」に変化したら、前記離氷モータ１１は前記製氷皿１０が水平位置に戻りｔ１２以内に停止する。 If the signal of the position detecting means 6 changes from “L → H” within t21 at the position number (3) in the ice removal motor 11, the ice detecting lever 12 is filled with ice in the ice storage box 9. Therefore, the ice tray is placed in a horizontal position without removing the ice from the ice tray. For this reason, when the control device 16 switches to the reverse operation and the signal of the position detecting means 6 changes from “L → H”, the ice removing motor 11 returns the ice tray 10 to the horizontal position and stops within t12. .
　次に満氷動作の時に、前記位置検知手段６の信号に前記制御装置１６のチャタリング等のノイズが入った場合について説明する。 Next, the case where noise such as chattering of the control device 16 enters the signal of the position detecting means 6 during the full ice operation will be described.
　前記製氷皿１０内の水が氷になったら、前記離氷モータ１１は、前記制御装置１６からの前記モータ駆動手段１８を介して、正転動作する信号が送られ、前記製氷皿１０は正転動作を開始し、ｔ１４後に前記位置検知手段６の信号は「Ｌ」になる。 When the water in the ice tray 10 becomes ice, the ice removing motor 11 is sent a signal for normal rotation via the motor driving means 18 from the control device 16, and the ice tray 10 is The rolling operation is started, and after t14, the signal of the position detecting means 6 becomes “L”.
　前記離氷モータ１１が、位置番号（３）でｔ２１以内に前記６の信号が「Ｌ→Ｈ」に変化したら、前記検氷レバー１２が、前記貯氷箱９内の氷が満氷と検知したこととなるため、前記製氷皿の氷を離氷することなく、前記製氷皿を水平位置にする。このため、前記制御装置１６により逆転動作に切り替わる。この逆転動作中に前記制御装置１６のチャタリング等のノイズが入り、前記位置検知手段６の信号が数回「Ｌ→Ｈ」に変化したら、前記離氷モータ１１を制御する制御装置１６は前記製氷皿１０が水平位置に戻ったと誤検知し、その場で前記離氷モータ１１の逆転動作を停止し、前記製氷皿１０が斜め状態での停止となる。 When the ice removal motor 11 detects that the ice in the ice storage box 9 is full when the signal of 6 changes from “L → H” within t21 at position number (3). Therefore, the ice tray is placed in a horizontal position without removing the ice from the ice tray. For this reason, the control device 16 switches to a reverse operation. When noise such as chattering of the control device 16 enters during the reverse rotation operation and the signal of the position detecting means 6 changes from “L to H” several times, the control device 16 that controls the ice removing motor 11 performs the ice making. When the dish 10 is erroneously detected to return to the horizontal position, the reverse operation of the ice removing motor 11 is stopped on the spot, and the ice tray 10 is stopped in an oblique state.
　図５の本発明の実施の形態における冷蔵庫の製氷機の誤検知の制御タイミングチャートにより動作の説明を行う。 The operation will be described with reference to a control timing chart of erroneous detection of the ice machine of the refrigerator in the embodiment of the present invention in FIG.
　満氷動作の時に、前記位置検知手段６の信号に前記制御装置１６のチャタリング等のノイズが入った場合について説明する。 A case where noise such as chattering of the control device 16 enters the signal of the position detection means 6 during the full ice operation will be described.
　前記製氷皿１０内の水が氷になったら、前記離氷モータ１１は、前記制御装置１６からの前記モータ駆動手段１８を介して、正転動作する信号が送られ、前記製氷皿１０は正転動作を開始し、ｔ１４後に前記位置検知手段６の信号は「Ｌ」になる。 When the water in the ice tray 10 becomes ice, the ice removing motor 11 is sent a signal for normal rotation via the motor driving means 18 from the control device 16, and the ice tray 10 is The rolling operation is started, and after t14, the signal of the position detecting means 6 becomes “L”.
　前記離氷モータ１１が、位置番号（３）でｔ２１以内に前記位置検知手段６の信号が「Ｌ→Ｈ」に変化したら、前記検氷レバー１２が、前記貯氷箱９内の氷が満氷と検知したこととなるため、前記製氷皿の氷を離氷することなく、前記製氷皿を水平位置にする。このため、前記制御装置１６により逆転動作に切り替わる。この逆転動作中に前記制御装置１６のチャタリング等のノイズが入り、前記位置検知手段６の信号が数回「Ｌ→Ｈ」に変化したら、前記離氷モータ１１を制御する制御装置１６は前記製氷皿１０が水平位置に戻ったと誤検知する。従って、満氷を検知後、ｔｍ内は、前記位置検知手段６の信号を前記制御装置１６が無視する制御を行うことにより、前記製氷皿１０が斜め状態での停止することを回避し、前記製氷皿１０を水平位置で停止することができる。 If the signal of the position detecting means 6 changes from “L → H” within t21 at the position number (3) in the ice removal motor 11, the ice detecting lever 12 is filled with ice in the ice storage box 9. Therefore, the ice tray is placed in a horizontal position without removing the ice from the ice tray. For this reason, the control device 16 switches to a reverse operation. When noise such as chattering of the control device 16 enters during the reverse rotation operation and the signal of the position detecting means 6 changes from “L → H” several times, the control device 16 that controls the ice removing motor 11 performs the ice making. It erroneously detects that the pan 10 has returned to the horizontal position. Therefore, after detecting the full ice, during tm, the control device 16 performs control to ignore the signal of the position detection means 6 to avoid the ice tray 10 from being stopped in an oblique state. The ice tray 10 can be stopped at a horizontal position.
　以上のように、本実施の形態においては、離氷モータ１１が正転時に、位置検知手段６にて貯氷箱９が満氷と検知した場合、離氷モータ１１が逆転となり、位置か満氷の誤検知を防止のため所定の位置検知手段６を検知しないため、例え位置検知手段６が誤検知しても、製氷皿が斜めで停止することなく、確実に製氷皿を水平位置に動作できる。 As described above, in the present embodiment, if the ice storage box 9 is detected to be full by the position detection means 6 when the ice release motor 11 is rotating forward, the ice release motor 11 is reversed and the position of the ice release motor 11 is In order to prevent erroneous detection, the predetermined position detection means 6 is not detected. Therefore, even if the position detection means 6 detects an error, the ice tray can be reliably moved to the horizontal position without stopping obliquely. .
　（実施の形態２）
　図６の本発明の実施例２における冷蔵庫の製氷機の誤検知の制御タイミングチャートにより動作の説明を行う。 (Embodiment 2)
The operation will be described with reference to a control timing chart of erroneous detection of the refrigerator ice maker in Embodiment 2 of the present invention in FIG.
　満氷動作の時に、前記位置検知手段６の信号に前記制御装置１６のチャタリング等のノイズが入った場合について説明する。 A case where noise such as chattering of the control device 16 enters the signal of the position detection means 6 during the full ice operation will be described.
　前記製氷皿１０内の水が氷になったら、前記離氷モータ１１は、前記制御装置１６からの前記モータ駆動手段１８を介して、正転動作する信号が送られ、前記製氷皿１０は正転動作を開始し、ｔ１４後に前記位置検知手段６の信号は「Ｌ」になる。 When the water in the ice tray 10 becomes ice, the ice removing motor 11 is sent a signal for normal rotation via the motor driving means 18 from the control device 16, and the ice tray 10 is The rolling operation is started, and after t14, the signal of the position detecting means 6 becomes “L”.
　前記離氷モータ１１が、位置番号（３）でｔ２１以内に前記位置検知手段６の信号が「Ｌ→Ｈ」に変化したら、前記検氷レバー１２が、前記貯氷箱９内の氷が満氷と検知したこととなるため、前記製氷皿の氷を離氷することなく、前記製氷皿を水平位置にする。このため、前記制御装置１６により逆転動作に切り替わる。この逆転動作中に前記制御装置１６のチャタリング等のノイズが入り、前記位置検知手段６の信号が数回「Ｌ→Ｈ」に変化したら、前記離氷モータ１１は前記製氷皿１０が水平位置に戻ったと勘違いをし、その場で前記離氷モータ１１の逆転動作を停止し、前記製氷皿１０が斜め状態での停止となる。 If the signal of the position detecting means 6 changes from “L → H” within t21 at the position number (3) in the ice removal motor 11, the ice detecting lever 12 is filled with ice in the ice storage box 9. Therefore, the ice tray is placed in a horizontal position without removing the ice from the ice tray. For this reason, the control device 16 switches to a reverse operation. When noise such as chattering of the control device 16 enters during the reverse rotation operation and the signal of the position detection means 6 changes from “L to H” several times, the ice-breaking motor 11 causes the ice tray 10 to move to the horizontal position. It is mistaken that it has returned, the reverse operation of the ice removing motor 11 is stopped on the spot, and the ice tray 10 is stopped in an oblique state.
　位置番号（４）で前記製氷皿１０が斜め状態での停止の場合、前記検氷レバー１２は機構的にフリーな状態となり、位置検知手段６の信号は「Ｌ」となる。このため、水平位置での停止は、「Ｈ」となることを検知して、前記制御装置１６は、前記製氷皿１０が水平常態での停止時、前記位置検知手段６の信号が「Ｌ」の場合は、斜め停止と判断し、その後、前記製氷皿１０を水平位置にする初期化動作を行う。 When the ice tray 10 is stopped in the oblique state at the position number (4), the ice detecting lever 12 is in a mechanically free state, and the signal of the position detecting means 6 is “L”. For this reason, it is detected that the stop at the horizontal position becomes “H”, and the control device 16 detects that the signal of the position detecting means 6 is “L” when the ice tray 10 is stopped in the horizontal normal state. In this case, it is determined that the stop is oblique, and then an initialization operation is performed to place the ice tray 10 in a horizontal position.
　初期化動作は、前記離氷モータ１１を逆転させる、逆転動作中に位置検知手段６の信号が「Ｈ」の状態でｔ１２継続すると、前記製氷皿１０が水平な状態と判断し停止する。 The initialization operation reverses the ice removing motor 11, and when the signal of the position detection means 6 continues for t12 during the reverse rotation operation, the ice tray 10 is determined to be in a horizontal state and is stopped.
　次に、ｔ３０停止させ、その後正転させる、正転動作を開始してから、前記位置検知手段６の信号が「Ｈ→Ｌ」を検知し、ｔ１３の場所で停止となる。次にｔ３０停止させた後、逆転させる。 Next, after starting the forward rotation operation that stops at t30 and then rotates forward, the signal of the position detecting means 6 detects “H → L”, and stops at the location of t13. Next, after stopping at t30, the rotation is reversed.
　前記位置検知手段６の信号が「Ｌ→Ｈ」を検知したところで 前記離氷モータ１１を停止させる。 When the signal of the position detecting means 6 detects “L → H”, the ice removing motor 11 is stopped.
　以上のように、本実施の形態においては、離氷モータが正転時に、位置検知手段にて貯氷箱が満氷と検知した場合、離氷モータが逆転となり、位置か満氷の誤検知を防止のため所定の時間位置検知手段を検知しないため、位置検知手段が誤検知しても、製氷皿が斜めで停止することなく、確実に製氷皿を水平位置に動作できる、また離氷モータが正転時に、位置検知手段にて貯氷箱が満氷と検知した場合、離氷モータが逆転となり、位置か満氷の誤検知により、製氷皿が斜めに停止した場合は、再度製氷皿を水平の位置に戻す初期化動作を行うことができるため、所定の大きさの氷ができ、また氷を貯めている貯氷箱への水が流れ込みもなく、貯めている氷を溶かすことがないので、使用者に対して常に高品位の氷を提供する。 As described above, in the present embodiment, when the ice storage motor detects that the ice storage box is full when the ice detection motor is rotating forward, the ice detection motor is reversed and erroneous detection of the position or full ice is detected. Since the position detection means is not detected for a predetermined time for prevention, even if the position detection means detects it incorrectly, the ice tray can be moved to a horizontal position without stopping at an angle, and the ice removal motor During normal rotation, if the ice storage box detects that the ice storage box is full by the position detection means, the ice-breaking motor will reverse, and if the ice tray stops diagonally due to incorrect detection of the position or full ice, the ice tray will be leveled again. Because the initialization operation to return to the position of can be performed, ice of a predetermined size can be made, water does not flow into the ice storage box storing ice, and the stored ice will not melt, Always provide high quality ice to the user.
　本発明にかかる冷蔵庫は、所定の大きさの氷ができる。また、氷を貯めている貯氷箱への水が流れ込みもなく、貯めている氷を溶かすことがないので、使用者に対して常に高品位の氷を提供することのできる冷蔵庫である。製氷装置搭載の冷蔵庫としてシステムキッチン収納庫や各種貯蔵庫等にも適用できるものである。 The refrigerator according to the present invention can produce ice of a predetermined size. Further, since the water does not flow into the ice storage box storing ice and does not melt the stored ice, the refrigerator can always provide high-quality ice to the user. As a refrigerator equipped with an ice making device, it can be applied to a system kitchen storage and various storages.
