Description

この発明は、貯氷検知ユニットの取付構造に関し、更に詳細には、製氷機の貯氷量を検知する貯氷検知ユニットの取付構造に関するものである。   The present invention relates to an ice storage detection unit mounting structure, and more particularly to an ice storage detection unit mounting structure for detecting an ice storage amount of an ice making machine.

例えば、所謂クローズドセルタイプと云われる噴射式製氷機には、貯氷庫の上方に配設された取付部材の下面に貯氷検知ユニットが設けられ、該貯氷検知ユニットにより貯氷庫内が満氷となったことを検知するようになっている。図６は、従来の貯氷検知ユニットの取付構造を概略的に示す説明図であって、この貯氷検知ユニット１０は、製氷機本体１２の天井部を構成する機構枠部(取付部材)１４の下面に、ネジ１６を介して取付けられるようになっている。具体的には、貯氷検知ユニット１０の上部に、一方側にフランジ１８が形成された取付ブラケット２０が設けられると共に、機構枠部１４に角穴部２２が開設されている。そして、前記取付ブラケット２０のフランジ１８を角穴部２２の縁部に係止させた状態で、該取付ブラケット２０の他方側を前記ネジ１６で機構枠部１４に固定することで、該機構枠部１４に貯氷検知ユニット１０が取付けられる。   For example, in a so-called closed cell type injection type ice making machine, an ice storage detection unit is provided on the lower surface of a mounting member disposed above the ice storage, and the ice storage is filled with the ice storage detection unit. It comes to detect that. FIG. 6 is an explanatory diagram schematically showing a conventional ice storage detection unit mounting structure. The ice storage detection unit 10 is a lower surface of a mechanism frame (attachment member) 14 constituting the ceiling of the ice making machine body 12. Further, it can be attached via a screw 16. Specifically, an attachment bracket 20 having a flange 18 formed on one side is provided on the upper part of the ice storage detection unit 10, and a square hole portion 22 is opened in the mechanism frame portion 14. Then, the other side of the mounting bracket 20 is fixed to the mechanism frame portion 14 with the screw 16 in a state where the flange 18 of the mounting bracket 20 is locked to the edge portion of the square hole portion 22. The ice storage detection unit 10 is attached to the part 14.

なお、貯氷検知ユニット１０から導出するリード線２４は、前記機構枠部１４の後部側に開設した切欠部２６を介して該機構枠部１４の上面側へ案内される。そして、機構枠部１４の上面側に案内されたリード線２４は、製氷機の統括的な運転制御を行なう制御部(図示せず)のリード線２８とコネクタ端子３０を介して接続されている。
特開２００２−３６４９６２号公報 The lead wire 24 led out from the ice storage detection unit 10 is guided to the upper surface side of the mechanism frame portion 14 through a notch 26 opened on the rear side of the mechanism frame portion 14. The lead wire 24 guided to the upper surface side of the mechanism frame portion 14 is connected via a connector terminal 30 to a lead wire 28 of a control unit (not shown) that performs overall operation control of the ice making machine. .
Japanese Patent Laid-Open No. 2002-364962

ところで、メンテナンスに際して前記貯氷検知ユニット１０を機構枠部１４から取外す場合、該機構枠部１４を製氷機本体１２から外した後に、貯氷検知ユニット１０を機構枠部１４から取外していては、大掛かりな作業となって時間を要してしまう。そのため、通常は、貯氷検知ユニット１０の下方に位置する貯氷庫の氷取出口(何れも図示せず)を介して貯氷検知ユニット１０を機構枠部１４から取外すことが行なわれている。しかしながら、前述の如く、貯氷検知ユニット１０は機構枠部１４にネジ止めされているので、作業者は、氷取出口から腕を庫内に挿入して前記ネジ１６を取外さなければならず、取外し作業が非常に煩雑となる難点があった。また、貯氷検知ユニット１０のリード線２４は、機構枠部１４の後側から上面側へ案内されているため、庫内前側での貯氷検知ユニット１０の取外し作業に加え、リード線２８から取外した庫外でのコネクタ端子３０を含むリード線２４を、機構枠部１４の後側から庫内側へ引き抜く作業が必要となるため、更なる作業効率の低下を招いていた。   By the way, when removing the ice storage detection unit 10 from the mechanism frame portion 14 during maintenance, it is not necessary to remove the ice storage detection unit 10 from the mechanism frame portion 14 after removing the mechanism frame portion 14 from the ice making machine main body 12. It takes time to work. Therefore, normally, the ice storage detection unit 10 is removed from the mechanism frame portion 14 via an ice take-out port (none of which is shown) of the ice storage located below the ice storage detection unit 10. However, since the ice storage detection unit 10 is screwed to the mechanism frame portion 14 as described above, the operator must remove the screw 16 by inserting his arm into the cabinet from the ice outlet. There was a difficulty that the work became very complicated. Further, since the lead wire 24 of the ice storage detection unit 10 is guided from the rear side of the mechanism frame portion 14 to the upper surface side, the lead wire 24 was removed from the lead wire 28 in addition to the removal operation of the ice storage detection unit 10 on the front side in the cabinet. Since it is necessary to pull out the lead wires 24 including the connector terminals 30 outside the chamber from the rear side of the mechanism frame portion 14 to the inside of the chamber, the work efficiency is further reduced.

なお、リード線２４を機構枠部１４の前側から上面側へ配線することで、リード線２４を機構枠部１４の後側から引き抜く作業を省略できるが、この場合は、通常時において庫内前側に垂れ下がるリード線２４を保持するための別部材を設ける必要があり、部品点数が増えてコストが嵩む問題を招く。   The lead wire 24 is wired from the front side of the mechanism frame portion 14 to the upper surface side, so that the work of pulling out the lead wire 24 from the rear side of the mechanism frame portion 14 can be omitted. It is necessary to provide another member for holding the lead wire 24 that hangs down, resulting in an increase in the number of parts and an increase in cost.

そこで本発明は、従来の貯氷検知ユニットの取付構造に内在する前記問題に鑑み、これを好適に解決するべく提案されたものであって、取付部材への着脱を容易にし得ると共に、リード線の配線も良好に行ない得る貯氷検知ユニットの取付構造を提供することを目的とする。   Accordingly, the present invention has been proposed to solve this problem in view of the above-mentioned problems inherent in the conventional ice storage detection unit mounting structure, and can be easily attached to and detached from the mounting member, and the lead wire An object of the present invention is to provide an ice storage detection unit mounting structure that can perform wiring well.

前記弾性部材７２は、可撓性を備えた金属板または合成樹脂板を側面視で略Ｕ字状に成型した樋状部材であって、該弾性部材７２には、左右および上方に開放して検知部７０のリード線９０,９０を案内する案内空間(空間部)１０２が画成されている。また、弾性部材７２は、該弾性部材７２の前面を構成する押圧面部１０４を後方へ押圧することで、弾性変形し得るようになっている。前記押圧面部１０４には、機構枠部４０の前記第２係止部６０が前面側から係合する係合通孔(第２被係止部)１０４ａが開設されている。前記弾性部材７２の後側の面を構成する閉塞面部１０６は、弾性部材７２を前記ユニット本体６６の前面側に取付けた際に前記前面開口部８０を閉塞するよう構成される。また、閉塞面部１０６の後面には、前記ユニット本体６６の前面に設けた前記係合穴８８,８８に挿入係合する一対の係合片１０６ａ,１０６ａが形成されている。   The elastic member 72 is a bowl-shaped member obtained by molding a flexible metal plate or synthetic resin plate into a substantially U shape in a side view, and the elastic member 72 is open to the left and right and above. A guide space (space portion) 102 for guiding the lead wires 90 and 90 of the detection unit 70 is defined. The elastic member 72 can be elastically deformed by pressing the pressing surface portion 104 constituting the front surface of the elastic member 72 rearward. In the pressing surface portion 104, an engagement through hole (second locked portion) 104a is formed in which the second locking portion 60 of the mechanism frame portion 40 is engaged from the front side. The closing surface portion 106 constituting the rear surface of the elastic member 72 is configured to close the front opening 80 when the elastic member 72 is attached to the front surface side of the unit main body 66. A pair of engagement pieces 106 a and 106 a that are inserted and engaged with the engagement holes 88 and 88 provided in the front surface of the unit main body 66 are formed on the rear surface of the closing surface portion 106.

ここで、図２に示すように、前記ユニット本体６６の差込部７６の後端から前記弾性部材７２の前面(すなわち、押圧面部１０４の前面)までの離間距離は、前記第１係止部５８,５８の凹部６２,６２後端から第２係止部６０の後面までの離間距離と略一致する値に設定されている。従って、貯氷検知ユニット６４を機構枠部４０に取付ける際に、弾性部材７２を後方へ弾性変形させることで両第１,第２係止部５８,６０間にユニット本体６６および弾性部材７２を配設することが可能となる(図３(ｃ)参照)。なお、前記弾性部材７２の案内空間１０２は、弾性部材７２を機構枠部４０に取付けた際に、機構枠部４０により上方が閉塞されるようになっている。   Here, as shown in FIG. 2, the separation distance from the rear end of the insertion portion 76 of the unit main body 66 to the front surface of the elastic member 72 (that is, the front surface of the pressing surface portion 104) is the first locking portion. The distance between the rear ends of the concave portions 62 and 62 of the 58 and 58 and the rear surface of the second locking portion 60 is set to a value that substantially matches. Therefore, when the ice storage detection unit 64 is attached to the mechanism frame portion 40, the unit body 66 and the elastic member 72 are arranged between the first and second locking portions 58 and 60 by elastically deforming the elastic member 72 rearward. (See FIG. 3 (c)). The guide space 102 of the elastic member 72 is closed by the mechanism frame portion 40 when the elastic member 72 is attached to the mechanism frame portion 40.

図５に示すように、前記弾性部材７２の閉塞面部１０６における左側の縁部には、前記検知部７０のリード線９０,９０を前記案内空間１０２へ導入する第１切欠き１０８が形成されると共に、前記押圧面部１０４の右側の縁部に、案内空間１０２を通したリード線９０,９０を庫内の前面側へ送り出す第２切欠き１１０が形成されている。すなわち、前記検知部７０のリード線９０,９０は、前記収容部７８の側面開口部８２を介して、庫内に一旦導出された後、前記第１切欠き１０８から案内空間１０２内へ引き込まれ、更に第２切欠き１１０を介して案内空間１０２から弾性部材７２の前方へ引き出されるようになっている。また、両第１,第２切欠き１０８,１１０は、リード線９０,９０を収容した際に該リード線９０,９０を係合保持する機能を備えている。   As shown in FIG. 5, a first notch 108 for introducing the lead wires 90, 90 of the detection unit 70 into the guide space 102 is formed at the left edge of the closed surface portion 106 of the elastic member 72. At the same time, a second notch 110 is formed at the right edge of the pressing surface 104 to feed the lead wires 90, 90 passing through the guide space 102 to the front side in the cabinet. That is, the lead wires 90 and 90 of the detection unit 70 are once led out into the cabinet through the side opening 82 of the storage unit 78 and then drawn into the guide space 102 from the first cutout 108. Further, the elastic member 72 is pulled out from the guide space 102 via the second notch 110. The first and second cutouts 108 and 110 have a function of engaging and holding the lead wires 90 and 90 when the lead wires 90 and 90 are received.

(実施例の作用)
次に、実施例に係る貯氷検知ユニットの取付構造の作用について説明する。先ず、貯氷検知ユニット６４の各部材を組み付ける際には、前記ユニット本体６６の収容部７８に検知部７０を収容する。次に、前記レバー部９４を取付スペース８４内に挿入し、軸部６８ａ,６８ａをユニット本体６６の軸穴８６,８６に軸支して、レバー部９４をユニット本体６６に揺動自在に支持する。また、弾性部材７２の係合片１０６ａ,１０６ａをユニット本体６６の対応する係合穴８８,８８に係合させて、弾性部材７２をユニット本体６６の前面に取付ける。このとき、弾性部材７２の閉塞面部１０６が収容部７８の前面開口部８０を閉塞し、検知部７０が収容部７８内に収容保持される。また、検知部７０のリード線９０,９０は、前記収容部７８の側面開口部８２を介して収容部７８の外部へ引き出される。次いで、レバー部９４の環状片１００に前記検知板９６のフック部９６ａを係止させ、貯氷検知ユニット６４の組付けが完了する。 (Operation of Example)
Next, the operation of the mounting structure of the ice storage detection unit according to the embodiment will be described. First, when the members of the ice storage detection unit 64 are assembled, the detection unit 70 is accommodated in the accommodation unit 78 of the unit main body 66. Next, the lever portion 94 is inserted into the mounting space 84, the shaft portions 68a and 68a are pivotally supported in the shaft holes 86 and 86 of the unit main body 66, and the lever portion 94 is swingably supported by the unit main body 66. To do. Further, the engagement pieces 106 a and 106 a of the elastic member 72 are engaged with the corresponding engagement holes 88 and 88 of the unit main body 66, and the elastic member 72 is attached to the front surface of the unit main body 66. At this time, the closing surface portion 106 of the elastic member 72 closes the front opening 80 of the housing portion 78, and the detection portion 70 is housed and held in the housing portion 78. In addition, the lead wires 90 and 90 of the detection unit 70 are drawn out of the storage unit 78 through the side opening 82 of the storage unit 78. Next, the hook portion 96a of the detection plate 96 is engaged with the annular piece 100 of the lever portion 94, and the assembly of the ice storage detection unit 64 is completed.

前記貯氷検知ユニット６４を機構枠部４０に取付ける際には、図３(ａ)に示すように、ユニット本体６６の差込部７６を機構枠部４０の両第１係止部５８,５８の凹部６２,６２に差し込む。次に、前記弾性部材７２の押圧面部１０４を後方へ押圧して、弾性部材７２を弾性変形させる(図３(ｂ))。そして、図３(ｃ)に示すように、弾性部材７２を弾性変形させたまま両第１,第２係止部５８,６０間に貯氷検知ユニット６４(ユニット本体６６および弾性部材７２)を臨ませ、弾性部材７２の押圧面部１０４に設けた係合通孔１０４ａに第２係止部６０を前側から挿入させる。この状態で、押圧面部１０４への押圧を解除すると、弾性部材７２は弾性復帰して前記係合通孔１０４ａに第２係止部６０が係合する。こうして、図３(ｄ)に示す如く、貯氷検知ユニット６４が機構枠部４０の下面に取付けられる。このように、実施例に係る貯氷検知ユニット６４の取付構造によれば、弾性部材７２を押圧するだけで容易に貯氷検知ユニット６４を機構枠部４０に取付けることが可能となる。   When the ice storage detection unit 64 is attached to the mechanism frame portion 40, as shown in FIG. 3A, the insertion portion 76 of the unit body 66 is connected to the first locking portions 58, 58 of the mechanism frame portion 40. Insert into the recesses 62, 62. Next, the pressing surface portion 104 of the elastic member 72 is pressed backward to elastically deform the elastic member 72 (FIG. 3B). Then, as shown in FIG. 3C, the ice storage detection unit 64 (unit main body 66 and elastic member 72) is exposed between the first and second locking portions 58 and 60 while the elastic member 72 is elastically deformed. The second locking portion 60 is inserted from the front side into the engagement through hole 104a provided in the pressing surface portion 104 of the elastic member 72. In this state, when the pressing to the pressing surface portion 104 is released, the elastic member 72 is elastically restored, and the second locking portion 60 is engaged with the engaging through hole 104a. In this way, the ice storage detection unit 64 is attached to the lower surface of the mechanism frame 40 as shown in FIG. Thus, according to the mounting structure of the ice storage detection unit 64 according to the embodiment, it is possible to easily attach the ice storage detection unit 64 to the mechanism frame portion 40 only by pressing the elastic member 72.

次に、前記ユニット本体６６の側面開口部８２から導出する検知部７０のリード線９０,９０を、弾性部材７２の案内空間１０２に引き込ませる。すなわち、閉塞面部１０６に設けた第１切欠き１０８を介してリード線９０,９０を案内空間１０２内へ引き込む。そして、案内空間１０２内を通したリード線９０,９０を、押圧面部１０４に設けた第２切欠き１１０を介して該押圧面部１０４の前側へ引き出させる。こうして、図５に示すように、検知部７０のリード線９０,９０は、庫内における貯氷検知ユニット６４の前面側に引き出すことができ、配線作業が極めて容易となる。しかも、弾性部材７２の両切欠き１０８,１１０により、リード線９０,９０を確実に保持した状態で案内し得る。なお、貯氷検知ユニット６４を機構枠部４０に取付ける前に、予めリード線９０,９０を第１,第２切欠き１０８,１１０に係合させ、案内空間１０２に案内させた状態とした後に、貯氷検知ユニット６４を機構枠部４０に取付けるようにしてもよい。   Next, the lead wires 90 and 90 of the detection unit 70 led out from the side opening 82 of the unit main body 66 are drawn into the guide space 102 of the elastic member 72. That is, the lead wires 90 and 90 are drawn into the guide space 102 through the first notch 108 provided in the closing surface portion 106. Then, the lead wires 90 passing through the guide space 102 are drawn out to the front side of the pressing surface portion 104 through the second notch 110 provided in the pressing surface portion 104. In this way, as shown in FIG. 5, the lead wires 90, 90 of the detection unit 70 can be pulled out to the front side of the ice storage detection unit 64 in the warehouse, and wiring work is extremely easy. Moreover, the lead wires 90 and 90 can be guided while being reliably held by the notches 108 and 110 of the elastic member 72. Before the ice storage detection unit 64 is attached to the mechanism frame 40, the lead wires 90 and 90 are engaged with the first and second cutouts 108 and 110 in advance to be guided to the guide space 102. The ice storage detection unit 64 may be attached to the mechanism frame portion 40.

貯氷検知ユニット６４を機構枠部４０から取外す際には、上記と逆の手順で行なわれる。すなわち、前記リード線９０,９０に対する第１,第２切欠き１０８,１１０による係合を解除して前記案内空間１０２からリード線９０,９０を引き出す。そして、弾性部材７２の押圧面部１０４を押圧して係合通孔１０４ａおよび第２係止部６０の係合を解除し、貯氷検知ユニット６４を庫内手前側に引き出すことで該貯氷検知ユニット６４が機構枠部４０から取外される。こうして、貯氷検知ユニット６４は、庫内の前側から弾性部材７２を押圧することで機構枠部４０から取外すことができる。なお、上記手順についても、予め貯氷検知ユニット６４を機構枠部４０から取外した後に、案内空間１０２および第１,第２切欠き１０８,１１０によるリード線９０,９０の案内を解除するようにしてもよい。   When removing the ice storage detection unit 64 from the mechanism frame 40, the procedure is reversed. That is, the first and second cutouts 108 and 110 are disengaged from the lead wires 90 and 90, and the lead wires 90 and 90 are pulled out from the guide space 102. Then, the pressing surface portion 104 of the elastic member 72 is pressed to release the engagement of the engagement through-hole 104a and the second locking portion 60, and the ice storage detection unit 64 is pulled out to the front side in the refrigerator, thereby the ice storage detection unit 64. Is removed from the mechanism frame 40. In this way, the ice storage detection unit 64 can be detached from the mechanism frame portion 40 by pressing the elastic member 72 from the front side in the cabinet. As for the above procedure, after the ice storage detection unit 64 is removed from the mechanism frame 40 in advance, the guidance of the lead wires 90 and 90 by the guide space 102 and the first and second cutouts 108 and 110 is canceled. Also good.

以上に説明したように、実施例に係る貯氷検知ユニットの取付構造によれば、貯氷検知ユニット６４をワンタッチで容易に着脱することができる。従って、噴射式製氷機３２の天板３８を取外さなくても、製氷機本体３４からフロントパネル３９を取り外し、前方開口部３７を介して庫内側から貯氷検知ユニット６４を着脱することができる。また、検知部７０のリード線９０,９０は、貯氷検知ユニット６４の前面側に引き出すことができるので、該リード線９０,９０の配線をスムーズに行ない得る。更に、弾性部材７２にリード線９０,９０を案内するための第１,第２切欠き１０８,１１０を設けたので、該リード線９０,９０を結束保持した状態で確実に案内することができ、リード線９０,９０を案内するための部材を別途設ける必要はない。   As described above, according to the ice storage detection unit mounting structure according to the embodiment, the ice storage detection unit 64 can be easily attached and detached with one touch. Therefore, the front panel 39 can be removed from the ice making machine main body 34 and the ice storage detection unit 64 can be attached and detached from the inside of the warehouse via the front opening 37 without removing the top plate 38 of the jet ice making machine 32. Moreover, since the lead wires 90 and 90 of the detection part 70 can be pulled out to the front side of the ice storage detection unit 64, the lead wires 90 and 90 can be wired smoothly. Further, since the first and second cutouts 108 and 110 for guiding the lead wires 90 and 90 are provided in the elastic member 72, the lead wires 90 and 90 can be reliably guided in a state of being held in a bundle. There is no need to separately provide a member for guiding the lead wires 90 and 90.

なお、実施例では、噴射式製氷機３２に貯氷検知ユニット６４を取付けた場合を示したが、製氷機としては実施例に限定される訳でなく、貯氷庫５２の上方に貯氷検知ユニット６４が臨むよう配設させ得るものであれば、如何なるタイプの製氷機であっても本発明を適用し得る。また、実施例では、製氷部４４等を支持する機構枠部４０に貯氷検知ユニット６４を取付けた場合を示したが、貯氷検知ユニット６４の取付部材としては、この機構枠部４０に限られず、例えば、製氷機の天板３８に直接取付けるようにしてもよい。   In the embodiment, the case where the ice storage detection unit 64 is attached to the jet ice making machine 32 is shown. However, the ice making machine is not limited to the embodiment, and the ice storage detection unit 64 is provided above the ice storage 52. The present invention can be applied to any type of ice making machine as long as it can be arranged to face. In the embodiment, the ice storage detection unit 64 is attached to the mechanism frame portion 40 that supports the ice making portion 44 and the like. However, the attachment member of the ice storage detection unit 64 is not limited to the mechanism frame portion 40. For example, you may make it attach directly to the top plate 38 of an ice machine.

更に、貯氷検知ユニット６４のユニット本体６６および揺動部材６８の構成については、実施例で示したものに限定されず、適宜変更することが可能である。また、実施例で説明した第１係止部５８,５８および差込部７６や第２係止部６０および係合通孔１０４ａの係合構造は、一例を示したものであり、他の係合構造を適宜採用可能である。例えば、第１被係止部(差込部７６)を凹状に、第１係止部５８と凸状に形成して、第１被係止部に第１係止部５８を挿通係合させる構成とすることが可能である。   Further, the configurations of the unit main body 66 and the swing member 68 of the ice storage detection unit 64 are not limited to those shown in the embodiments, and can be appropriately changed. In addition, the engagement structure of the first locking portions 58, 58 and the insertion portion 76, the second locking portion 60, and the engagement through hole 104a described in the embodiment is an example, and other engagement structures are shown. A combined structure can be adopted as appropriate. For example, the first locked portion (insertion portion 76) is formed in a concave shape and convex with the first locking portion 58, and the first locked portion 58 is inserted into and engaged with the first locked portion. It can be configured.
