Description

本発明は、製氷機の貯氷量を検知するための貯氷検知装置の取付構造に関する。 The present invention relates to a structure for mounting an ice storage detection device for detecting an ice storage amount of an ice making machine.

本発明に係る貯氷スイッチの取付構造は、金属製のビスや螺子などの締結部品を用いることなく貯氷スイッチを貯氷庫内に取り付ける、所謂「ビスレス構造」であるが、このようなビスレス構造の貯氷スイッチの取付構造自体は、特許文献１に開示されており公知である。 The ice storage switch mounting structure according to the present invention is a so-called “screwless structure” in which an ice storage switch is mounted in an ice storage without using a fastening part such as a metal screw or screw. The switch mounting structure itself is disclosed in Patent Document 1 and is well known.

特許文献１に記載の貯氷検知装置１７は、貯氷庫１１の上板１６に形成された開口部２８に貯氷庫１１の内部から脱着自在に嵌着される検知板ベース１８と、検知板ベース１８に回動可能に取り付けられる検知板１９と、検知板１９の回動を検知するリードスイッチ２０などで構成される。検知板ベース１８には、一対の爪部２２・２３が上向きに突設されており、これら爪部２２・２３の先端が、開口部２８の開口縁に係合されることで、検知装置１７は貯氷庫１１の上板１６に取り付けられる。上板１６には、開口部２８に隣接して一対の凹状の指挿入部２９・３０が形成されており、これら指挿入部２９・３０のそれぞれに指を挿入して、爪部２２・２３を互いに近づく方向に撓み変形させることにより、爪部２２・２３の先端と開口部２８の開口縁との間の係合を解除して、開口部２８から検知板ベース１８を取り外すことができる。 The ice storage detection device 17 described in Patent Document 1 includes a detection plate base 18 that is detachably fitted from the inside of the ice storage 11 into an opening 28 formed in the upper plate 16 of the ice storage 11, and a detection plate base 18. And a reed switch 20 for detecting the rotation of the detection plate 19. The detection plate base 18 is provided with a pair of claw portions 22, 23 protruding upward, and the tips of the claw portions 22, 23 are engaged with the opening edge of the opening 28, whereby the detection device 17. Is attached to the upper plate 16 of the ice storage 11. The upper plate 16 is formed with a pair of concave finger insertion portions 29 and 30 adjacent to the opening 28, and a finger is inserted into each of the finger insertion portions 29 and 30 so that the nail portions 22 and 23 are inserted. Are bent in the direction approaching each other, the engagement between the tips of the claw portions 22 and 23 and the opening edge of the opening 28 can be released, and the detection plate base 18 can be removed from the opening 28.

以上のような構成からなる特許文献１に記載の貯氷検知装置１７の取付構造によれば、ビスや螺子等の締結部品を一切用いることなく貯氷庫１１の上板１６の開口部２８に脱着自在に嵌着することができるので、貯氷庫１１の内部からの検知装置１７の取り外しが容易となり、貯氷検知装置１７の交換、修理、清掃等のメンテナンスも容易となる。ビスや螺子等の締結部材の貯氷庫１１内への落下のおそれもない。 According to the mounting structure of the ice storage detection device 17 described in Patent Document 1 having the above-described configuration, the ice storage 11 can be detachably attached to the opening 28 of the upper plate 16 without using any fastening parts such as screws and screws. Therefore, the detection device 17 can be easily removed from the ice storage 11, and maintenance such as replacement, repair, and cleaning of the ice storage detection device 17 is also facilitated. There is no risk of fastening members such as screws and screws falling into the ice storage 11.

特許文献１の取付構造では、貯氷庫１１に至るシューターのような狭隘な空間に臨むように検知装置１７を取り付ける際には、爪部２２・２３や指挿入部２９・３０へのアクセスが困難、或いは不可能となるために適用できない。また、特許文献１の取付構造では、上板１６には、開口部２８の外に、リードスイッチ２０のリード線４４を機械室に導くための貫通孔４７が形成されており、上板１６の上面の開口部２８と貫通孔４７との間には、リード線４４を這わすための溝状のコネクタ通路４８が刻設されているため、コネクタ通路４８を通ってリードスイッチ２０に至るリード線４４の余裕長さは数センチ程度の略皆無であって、上板１６から取り外した貯氷検知装置１７を貯氷庫１１側に大きく引き出すことができず、メンテナンス作業を作業効率良く進めることができず、この点にも不利がある。 With the mounting structure of Patent Document 1, when mounting the detection device 17 so as to face a narrow space such as a shooter that reaches the ice storage 11, it is difficult to access the nail portions 22 and 23 and the finger insertion portions 29 and 30. Or because it becomes impossible. Further, in the mounting structure of Patent Document 1, a through hole 47 for guiding the lead wire 44 of the reed switch 20 to the machine room is formed on the upper plate 16 outside the opening portion 28. A groove-like connector passage 48 for encircling the lead wire 44 is formed between the opening 28 on the upper surface and the through hole 47, so that the lead wire that reaches the reed switch 20 through the connector passage 48. 44 has a margin of about several centimeters, and the ice storage detection device 17 removed from the upper plate 16 cannot be pulled out largely to the ice storage 11 side, and the maintenance work cannot be performed efficiently. This is also disadvantageous.

本発明は、以上のような従来の貯氷検知装置の取付構造の抱える問題を解決するためになされたものであり、狭隘な空間に臨むように検知装置を取り付ける場合であっても、簡単確実に検知装置を取り付けることが可能であり、しかも、検知装置の部品補修や交換などのメンテナンス作業をより作業効率良く行うことできるようにすることを目的とする。 The present invention has been made to solve the problems of the mounting structure of the conventional ice storage detection device as described above. Even when the detection device is mounted so as to face a narrow space, it can be easily and reliably performed. An object of the present invention is to allow the detection device to be attached, and to perform maintenance work such as component repair and replacement of the detection device more efficiently.

The sensor main body 52 is connected to a lead wire 90 for transmitting a detection signal from the sensor main body 52. The base portion 67 of the holder 47 is formed with a lead guide portion 91 for leading the lead wire 90 extending from the detection device 40 toward the outer surface side of the wall surface W. Then, after the detection device 40 held by the support structure 68 is inserted into the ice storage space S from the outer surface side of the wall surface W through the mounting window 41, the lock structure 69 is engaged with the mounting seat 49, The base portion 67 is pressed against the opening edge of the mounting window 41, and the entire holder 47 is fixedly held so as not to be detached from the mounting window 41, and the engagement between the mounting seat 49 and the lock structure 69 is released. Thus, the detection device 40 can be extracted together with the holder 47 to the outer surface side of the wall surface W through the mounting window 41. The ice storage space S in the present invention is a concept including not only the internal space of the ice storage chamber 5 but also the ice piece guide space including the internal space of the chute 21 from the ice making unit 6 to the ice storage chamber 5.

壁面Ｗの外面側に位置する装着窓４１の開口縁には、中央開口８７を有する枠状のシール部材４８が装着されている。リード線９０は、ベース部６７の盤面中央に設けられたリードガイド部９１である通孔を介して、壁面Ｗの外面側に向かって導出されている。 A frame-shaped seal member 48 having a central opening 87 is mounted on the opening edge of the mounting window 41 located on the outer surface side of the wall surface W. The lead wire 90 is led out toward the outer surface side of the wall surface W through a through hole which is a lead guide portion 91 provided at the center of the board surface of the base portion 67.

ロック構造６９が、断面Ｕ字形の樋体状に形成されて、撓み変形可能な上下一対のロックアーム８２・８２を含む。各ロックアーム８２・８２の遊端に構成された係止爪８３・８３を、壁面Ｗの外面側の開口縁に形成された取付座４９・４９の装着溝６２・６２に係合させることにより、シール部材４８の外面にベース部６７の内面を押し付けて、装着窓４１の開口縁とベース部６７の周縁との間の隙間を封止することができるように構成されている。 The lock structure 69 includes a pair of upper and lower lock arms 82 and 82 that are formed in a housing shape having a U-shaped cross section and can be flexibly deformed. By engaging the locking claws 83 and 83 formed at the free ends of the lock arms 82 and 82 with the mounting grooves 62 and 62 of the mounting seats 49 and 49 formed at the opening edge on the outer surface side of the wall surface W. The inner surface of the base portion 67 is pressed against the outer surface of the seal member 48 so that the gap between the opening edge of the mounting window 41 and the peripheral edge of the base portion 67 can be sealed.

支持構造６８が、ベース部６７の内面から片持ち状に伸びる上下一対の腕壁７１・７２で構成されている。下腕壁７２が、ベース部６７の内面から内外方向に伸びる第１横腕壁７４と、第１横腕壁７４の遊端から下方に伸びる縦腕壁７５と、縦腕壁７５の遊端から内外方向に伸びる第２横腕壁７６とを含む、段付き状に形成されている。検知装置４０を構成するハウジング５０の前後壁が、ホルダー４７のベース部６７と下腕壁７２とに受け止められる段付き状に形成されている。そして、上下の腕壁７１・７２の遊端に、ハウジング５０の上下端に係合する係止リブ７３・７８が設けられている形態を採ることができる。 The support structure 68 includes a pair of upper and lower arm walls 71 and 72 that cantilever from the inner surface of the base portion 67. A lower arm wall 72 extends from the inner surface of the base portion 67 inward and outward, a vertical arm wall 75 extending downward from a free end of the first horizontal arm wall 74, and a free end of the vertical arm wall 75 And a second lateral arm wall 76 extending inwardly and outwardly from each other. The front and rear walls of the housing 50 constituting the detection device 40 are formed in a stepped shape that can be received by the base portion 67 and the lower arm wall 72 of the holder 47. And it can take the form by which the locking rib 73 * 78 engaged with the upper and lower ends of the housing 50 is provided in the free end of the upper and lower arm walls 71 * 72.

本発明において、検知装置４０を壁面に取り付ける際には、ホルダー４７の支持構造６８に検知装置４０を保持させた状態で、壁面Ｗの外面側から装着窓４１を介して貯氷空間Ｓ内に検知装置４０を差し込み、さらにホルダー４７のロック構造６９を壁面側の取付座４９に係合させることで、検知装置４０とホルダー４７とを装着窓４１に対して抜け外れ不能に固定保持させることができる。また、取付座４９とロック構造６９との間の係合を解除し、ホルダー４７と共に検知装置４０を装着窓４１を介して壁面Ｗの外面側に抜き出すことで、検知装置４０を壁面Ｗから取り外すことができる。以上のように、本発明の取付構造によれば、作業者は壁面Ｗの外面側から検知装置４０の取付作業、或いは検知装置４０の取り外し作業を行うことができ、貯氷空間Ｓ側（壁面Ｗの内面側）から検知装置４０の取付作業、或いは取り外し作業を行っていた従来形態（例えば特許文献１）とは異なり、貯氷空間Ｓ内での一切の作業を廃することができるので、検知装置４０のメンテナンス作業を作業効率良く、より容易に進めることができる。 In the present invention, when the detection device 40 is attached to the wall surface, the detection device 40 is held in the ice storage space S from the outer surface side of the wall surface W through the mounting window 41 while the detection device 40 is held by the support structure 68 of the holder 47. By inserting the device 40 and further engaging the lock structure 69 of the holder 47 with the mounting seat 49 on the wall surface side, the detection device 40 and the holder 47 can be fixedly held so as not to be detached from the mounting window 41. . Moreover, the engagement between the mounting seat 49 and the lock structure 69 is released, and the detection device 40 is removed from the wall surface W by extracting the detection device 40 together with the holder 47 to the outer surface side of the wall surface W through the mounting window 41. be able to. As described above, according to the mounting structure of the present invention, the operator can perform the mounting operation of the detection device 40 or the removal operation of the detection device 40 from the outer surface side of the wall surface W, and the ice storage space S side (wall surface W Unlike the conventional mode (for example, Patent Document 1) in which the detecting device 40 is attached or detached from the inner surface of the ice storage space S, all the operations in the ice storage space S can be eliminated. Forty maintenance operations can be carried out more efficiently and more easily.

詳しくは、本発明においては、ホルダー４７を固定保持するための取付座４９を壁面Ｗの外面側に設けたので、壁面Ｗの外面側からロック構造６９にアクセスすることでホルダー４７の取付作業、或いは取り外し作業を進めることができる。また、予めホルダー４７の支持構造６８に検知装置４０を保持させてから、該検知装置４０を壁面Ｗの外面側から装着窓４１を介して貯氷空間Ｓ内に差し込んで、取付作業を進めることができるので、検知装置４０のホルダー４７に対する保持作業も含めて、全ての取付作業を壁面Ｗの外面側で行うことができる。また、取り外し作業時には、ホルダー４７ごと装着窓４１を介して壁面Ｗの外面側に検知装置４０を抜き出すことができるので、検知装置４０の交換作業などの全てのメンテナンス作業を、壁面Ｗの外面側で行うことができる。このように、本発明の取付構造によれば、検知装置４０の壁面Ｗからの取り外し、検知装置４０の交換、そして検知装置４０の壁面Ｗへの取り付け、といった一連のメンテナンス作業の全てを壁面Ｗの外面側で行うことができるので、作業効率の格段の向上を図ることができる。また、以上のような本発明の作用効果は、検知装置４０が設置される貯氷空間Ｓが貯氷室５に至るシュート２１のような狭隘な空間である場合に、換言すれば、シュート２１のような狭隘な貯氷空間Ｓを検知装置４０の設置対象とする場合に特に有用となる。 Specifically, in the present invention, since the mounting seat 49 for fixing and holding the holder 47 is provided on the outer surface side of the wall surface W, the holder 47 is attached by accessing the lock structure 69 from the outer surface side of the wall surface W. Or removal work can be advanced. In addition, after the detection device 40 is held in the support structure 68 of the holder 47 in advance, the detection device 40 is inserted into the ice storage space S from the outer surface side of the wall surface W through the mounting window 41 to proceed with the mounting operation. Therefore, all the mounting operations including the holding operation of the detection device 40 with respect to the holder 47 can be performed on the outer surface side of the wall surface W. Moreover, since the detection device 40 can be extracted to the outer surface side of the wall surface W through the mounting window 41 together with the holder 47 during the removal operation, all maintenance work such as replacement of the detection device 40 is performed on the outer surface side of the wall surface W. Can be done. Thus, according to the mounting structure of the present invention, all of the series of maintenance operations such as removal of the detection device 40 from the wall surface W, replacement of the detection device 40, and attachment of the detection device 40 to the wall surface W are performed on the wall surface W. Therefore, the working efficiency can be remarkably improved. The above-described operational effects of the present invention can be obtained when the ice storage space S in which the detection device 40 is installed is a narrow space like the chute 21 reaching the ice storage chamber 5, in other words, like the chute 21. This is particularly useful when a narrow ice storage space S is an installation target of the detection device 40.

また、本発明では、ホルダー４７のベース部６７にリード線９０を壁面Ｗの外面側に向かって導出するためのリードガイド部９１を形成しており、このことはベース部６７のリードガイド部９１にガイドされるリード線９０の余裕長さが、最低でも検知装置４０およびホルダー４７の装着窓４１からの抜き出し作業時に支障が生じない程度に大きく設定されていることを意味している。以上より本発明によれば、壁面Ｗにリード線用の専用の貫通孔やコネクタ通路が形成されており、数センチ程度にリード線の余裕長さが決定されていた従来形態（例えば特許文献１）とは異なり、リード線の余裕長さを比較的大きくすることができるため、その分だけ検知装置４０やホルダー４７を装着窓４１から大きく引き出すことができ、この点でもメンテナンス作業等を作業効率良く進めることが可能となる。また、貫通孔やコネクタ通路などへの配線の手間が不要であり、この点でもメンテナンス作業等を作業効率良く進めることができる。 Further, in the present invention, the lead guide portion 91 for leading the lead wire 90 toward the outer surface side of the wall surface W is formed on the base portion 67 of the holder 47, which is the lead guide portion 91 of the base portion 67. This means that the margin length of the lead wire 90 to be guided is set to be large at least so as not to cause any trouble when the detection device 40 and the holder 47 are pulled out from the mounting window 41. As described above, according to the present invention, a dedicated through hole for a lead wire or a connector passage is formed on the wall surface W, and the lead wire margin length is determined to be about several centimeters (for example, Patent Document 1). ), The margin of the lead wire can be made relatively large, so that the detection device 40 and the holder 47 can be pulled out from the mounting window 41 by that much, and in this respect also maintenance work etc. It is possible to proceed well. Further, it is not necessary to carry out wiring to the through hole, the connector passage, and the like, and the maintenance work and the like can be efficiently performed in this respect.

加えて、本発明によれば、貯氷空間Ｓ内での作業を廃することができるので、取付作業やメンテナンス作業時に庫内が汚染されるおそれが少なく、貯氷空間Ｓの洗浄などの余分な手間が不要となる利点がある。また、本発明によれば、ビスや螺子等の締結部品を一切用いることなく、検知装置４０を壁面Ｗに着脱可能に取り付けることができるので、ビスや螺子等の締結部材の貯氷空間Ｓ内への落下のおそれがなく、当該取付構造が適用された製氷機の信頼性向上に貢献できる。 In addition, according to the present invention, since the work in the ice storage space S can be eliminated, there is little possibility that the inside of the warehouse is contaminated during the installation work or the maintenance work, and extra work such as cleaning of the ice storage space S is required. There is an advantage that becomes unnecessary. In addition, according to the present invention, the detection device 40 can be detachably attached to the wall surface W without using any fastening parts such as screws or screws, so that the ice storage space S of the fastening members such as screws and screws can be provided. There is no fear of falling, and it can contribute to improving the reliability of the ice making machine to which the mounting structure is applied.

壁面Ｗの外面側に位置する装着窓４１の開口縁に、中央開口８７を有する枠状のシール部材４８が装着されていると、装着窓４１とホルダー４７のベース部６７との間を封止して、装着窓４１から壁面Ｗの外面側への氷漏れや水漏れを確実に防止できる。リードガイド部９１をベース部６７の盤面中央に設けられた通孔とし、当該通孔９１を介して、リード線９０を壁面Ｗの外面側に向かって導出すると、シール部材４８を設けたことに伴ってリード線９０の引き回しが複雑化することを抑えて、シンプルな構成でリード線９０を壁面Ｗの外面側に引き出すことが可能となる。 When a frame-like seal member 48 having a central opening 87 is attached to the opening edge of the attachment window 41 located on the outer surface side of the wall surface W, the space between the attachment window 41 and the base portion 67 of the holder 47 is sealed. Thus, it is possible to reliably prevent ice leakage and water leakage from the mounting window 41 to the outer surface side of the wall surface W. When the lead guide portion 91 is a through hole provided in the center of the board surface of the base portion 67 and the lead wire 90 is led out toward the outer surface side of the wall surface W through the through hole 91, the seal member 48 is provided. Accordingly, it is possible to pull out the lead wire 90 to the outer surface side of the wall surface W with a simple configuration while suppressing the lead wire 90 from being complicated.

ロック構造６９が、断面Ｕ字形の樋体状に形成されて、撓み変形可能な上下一対のロックアーム８２・８２を含むものとして、各ロックアーム８２・８２の遊端に構成された係止爪８３・８３を、壁面Ｗの外面側の開口縁に形成された取付座４９・４９の装着溝６２・６２に係合させることで、ホルダー４７が取付座４９・４９に固定保持される構成を取ることができる。このようにロック構造６９を、断面Ｕ字形の樋体状に形成されて、撓み変形可能な上下一対のロックアームを含むものとしていると、上下の係止爪８３・８３が近付く方向に両ロックアーム８２・８２を撓み変形させたうえで、取付座４９・４９の装着溝６２・６２に係止爪８３・８３を位置合わせし、両ロックアーム８２・８２の撓み変形状態を解除するだけで、両ロックアーム８２・８２の弾性力によりホルダー４７を取付座４９・４９に固定保持することができる。また、逆の手順により、ホルダー４７の固定保持状態から両ロックアーム８２・８２が近付く方向に撓み変形させるだけで、取付座４９・４９の装着溝６２・６２に対する係止爪８３・８３の係合状態を解除して、ホルダー４７を取付座４９・４９から取り外すことができる。さらに、各ロックアーム８２・８２の遊端に構成された係止爪８３・８３を、壁面Ｗの外面側の開口縁に形成された取付座４９・４９の装着溝６２・６２に係合させることにより、シール部材４８の外面にベース部６７の内面を押し付けて、装着窓４１の開口縁とベース部６７の周縁との間の隙間を埋めることができるように構成すると、シール部材４８による封止状態をより確実なものとして、装着窓４１から壁面Ｗの外面側への氷漏れや水漏れをより確実に防止できる。 The lock structure 69 is formed in a U-shaped cross-section and includes a pair of upper and lower lock arms 82 and 82 that can be flexibly deformed, and a locking claw configured at the free end of each lock arm 82 and 82 A configuration in which the holder 47 is fixedly held by the mounting seats 49 and 49 by engaging the 83 and 83 with the mounting grooves 62 and 62 of the mounting seats 49 and 49 formed on the opening edge on the outer surface side of the wall surface W. Can be taken. As described above, when the lock structure 69 is formed in the shape of a U-shaped casing and includes a pair of upper and lower lock arms that can be flexibly deformed, both locks are provided in the direction in which the upper and lower locking claws 83 and 83 approach each other. After the arms 82 and 82 are bent and deformed, the locking claws 83 and 83 are aligned with the mounting grooves 62 and 62 of the mounting seats 49 and 49, and the bending deformation state of both lock arms 82 and 82 is released. The holder 47 can be fixedly held on the mounting seats 49 and 49 by the elastic force of the lock arms 82 and 82. In addition, the engagement of the locking claws 83 and 83 with respect to the mounting grooves 62 and 62 of the mounting seats 49 and 49 is simply performed by bending and deforming in the direction in which both the lock arms 82 and 82 approach from the fixed holding state of the holder 47 by the reverse procedure. The combined state is released, and the holder 47 can be removed from the mounting seats 49 and 49. Further, the locking claws 83 and 83 formed at the free ends of the lock arms 82 and 82 are engaged with the mounting grooves 62 and 62 of the mounting seats 49 and 49 formed at the opening edge on the outer surface side of the wall surface W.

ロック構造６９は、ベース部６７の上下端から連設された上下一対のロックアーム８２・８２と、各ロックアーム８２・８２の遊端に設けられて取付座４９の装着溝６２に係合する係止爪８３・８３とで構成される。図６に示すように、各ロックアーム８２・８２は、ベース部６７に連設された第１水平壁８２ａと、第１水平壁８２ａの遊端から上下方向に向かう反転壁８２ｂと、反転壁８２ｂに連設された第２水平壁８２ｃと、第２水平壁８２ｃの遊端から上下方向に折り返された係止壁８２ｄとからなり、撓み変形可能な樋体状に形成されている。係止壁８２ｄの前後方向の中央部には、前後一対の挟持壁８４・８４が形成されており、これら挟持壁８４・８４で取付座４９のリブ６４を挟持することで、ホルダー４７の前後方向の遊動が規制されている。また、これら挟持壁８４・８４で挟まれた係止壁８２ｄの中央部分が係止爪８３となっている（図５参照）。以上より、上下の係止爪８３・８３を、取付座４９の装着溝６２に係合させることにより、ホルダー４７の全体をシュート２１の装着窓４１に対して抜け外れ不能に固定保持することができる。また、上下の係止爪８３と取付座４９との間の係合を解除することで、ホルダー４７をシュート２１の装着窓４１から取り外すことができる。 The lock structure 69 is provided at a pair of upper and lower lock arms 82, 82 provided from the upper and lower ends of the base portion 67, and the free ends of the lock arms 82, 82 and engages with the mounting groove 62 of the mounting seat 49. It comprises locking claws 83 and 83. As shown in FIG. 6, each of the lock arms 82, 82 includes a first horizontal wall 82 a that is connected to the base portion 67, an inversion wall 82 b that extends from the free end of the first horizontal wall 82 a in the vertical direction, and an inversion wall. The second horizontal wall 82c connected to 82b and a locking wall 82d folded back in the vertical direction from the free end of the second horizontal wall 82c are formed into a deformable and deformable box shape. A pair of front and rear holding walls 84 and 84 are formed at the center in the front and rear direction of the locking wall 82d. By holding the ribs 64 of the mounting seat 49 between the holding walls 84 and 84, the front and rear of the holder 47 are formed. Directional play is restricted. Moreover, the center part of the locking wall 82d pinched | interposed by these clamping walls 84 * 84 is the latching claw 83 (refer FIG. 5). As described above, by engaging the upper and lower locking claws 83, 83 with the mounting groove 62 of the mounting seat 49, the entire holder 47 can be fixedly held so as not to be detached from the mounting window 41 of the chute 21. it can. Further, by releasing the engagement between the upper and lower locking claws 83 and the mounting seat 49, the holder 47 can be removed from the mounting window 41 of the chute 21.

図５および図６に示すように、ホルダー４７のベース部６７と装着窓４１との間を封止するシール部材４８は、中央開口８７を有する四角枠状に形成されたシリコンゴムなどを素材とする成形品である。シール部材４８の四周壁には、シュート２１の装着窓４１の開口縁を受け入れる装着溝８８が設けられており、当該装着溝８８内に装着窓４１の開口縁を侵入させることで、シール部材４８をシュート２１に仮止め状に装着することができる。この状態から、先のロック構造６９を使ってホルダー４７をシュート２１に固定保持させることで、シール部材４８の外面にベース部６７の内面（左面）を押し付けて、装着窓４１の開口縁とベース部６７との間の隙間を封止することができる。 As shown in FIGS. 5 and 6, the seal member 48 that seals between the base portion 67 of the holder 47 and the mounting window 41 is made of silicon rubber or the like formed in a square frame shape having a central opening 87 as a material. It is a molded product. A mounting groove 88 that receives the opening edge of the mounting window 41 of the chute 21 is provided on the four peripheral walls of the sealing member 48, and the sealing member 48 is inserted into the mounting groove 88 to allow the opening edge of the mounting window 41 to enter. Can be temporarily attached to the chute 21. From this state, the holder 47 is fixedly held on the chute 21 by using the lock structure 69, so that the inner surface (left surface) of the base portion 67 is pressed against the outer surface of the seal member 48, and the opening edge of the mounting window 41 and the base A gap between the portion 67 can be sealed.

近接スイッチ５２による検知信号は、該センサ５２から伸びるリード線９０を介して制御ボックス１７に送られるようになっており、ホルダー４７のベース部６７には、リード線９０をシュート２１の外面側に向かって導出するためのリードガイド部９１が形成されている。図１および図５に示すように、リードガイド部９１は、ベース部６７の盤面中央に設けられたリード線用の通孔であり、この通孔９１とシール部材４８の中央開口８７とを介して、リード線９０はシュート２１の外面側に導出されている。通孔９１にはパッキン９２が装着されており、このパッキン９２により、通孔９１とリード線９０との間の隙間が封止されている。 A detection signal from the proximity switch 52 is sent to the control box 17 via a lead wire 90 extending from the sensor 52, and the lead wire 90 is placed on the outer surface side of the chute 21 on the base portion 67 of the holder 47. A lead guide portion 91 for leading out is formed. As shown in FIGS. 1 and 5, the lead guide portion 91 is a lead wire through hole provided in the center of the board surface of the base portion 67, and the through hole 91 and the central opening 87 of the seal member 48 are interposed therebetween. The lead wire 90 is led out to the outer surface side of the chute 21. A packing 92 is attached to the through hole 91, and the gap between the through hole 91 and the lead wire 90 is sealed by the packing 92.

図３および図４において、符号９４は、ホルダー４７を含むシュート２１の全体を覆うように、該シュート２１に外嵌状に装着される中空容器状のカバーを示す。カバー９４は、発泡スチロール製の断熱体であり、機械室４とシュート２１との間の熱伝導を塞ぐ目的で装着される。カバー９４は、縦方向に二つに分割可能に構成されており、メンテナンス作業時等においては二分割することで、シュート２１から取り外すことができる。 3 and 4, reference numeral 94 denotes a hollow container-like cover that is mounted on the chute 21 so as to cover the entire chute 21 including the holder 47. The cover 94 is a heat insulating body made of polystyrene foam, and is attached for the purpose of blocking the heat conduction between the machine room 4 and the chute 21. The cover 94 is configured to be split into two in the vertical direction, and can be detached from the chute 21 by dividing the cover 94 into two during maintenance work or the like.

この取付構造では、満氷検知装置４０はシュート２１の貯溜部３５に以下の手順で装着される。まず、検知装置４０の近接スイッチ５２から伸びるリード線９０を、ホルダー４７のベース部６７に設けられたリードガイド部である通孔９１に通す。次に、支持構造６８を使って、検知装置４０をホルダー４７に保持させる。具体的には、腕壁７１・７２を拡開変形させながら、左方から検知装置４０を腕壁７１・７２の間に差し込み、ケース体５４の上下端を係止リブ７３・７８で係止して、検知装置４０を支持構造６８に保持させる。かかる保持状態において、ベース部６７の規制リブ８０・８０が前後の脚壁７７・７８の対向内面に接触することで、前後方向の検知装置４０のホルダー４７に対する遊動が規制される。以上のようなリード線９０の通孔９１への挿通作業、および支持構造６８に対する検知装置４０の保持作業はシュート２１の外側で行われる。機械室４の外側で行うこともできる。 In this mounting structure, the full ice detection device 40 is attached to the storage portion 35 of the chute 21 in the following procedure. First, the lead wire 90 extending from the proximity switch 52 of the detection device 40 is passed through the through hole 91 which is a lead guide portion provided in the base portion 67 of the holder 47. Next, the detection device 40 is held by the holder 47 using the support structure 68. Specifically, while expanding and deforming the arm walls 71 and 72, the detection device 40 is inserted between the arm walls 71 and 72 from the left, and the upper and lower ends of the case body 54 are locked by the locking ribs 73 and 78. Then, the detection device 40 is held on the support structure 68. In this holding state, the regulation ribs 80 and 80 of the base portion 67 come into contact with the opposing inner surfaces of the front and rear leg walls 77 and 78, so that the movement of the detection device 40 in the front-rear direction with respect to the holder 47 is restricted. The operation of inserting the lead wire 90 into the through hole 91 as described above and the operation of holding the detection device 40 with respect to the support structure 68 are performed outside the chute 21. It can also be performed outside the machine room 4.

次に、装着窓４１の開口縁にシール部材４８を仮止めした状態で、検知装置４０を貯溜部３５の外面側から装着窓４１とシール部材４８の中央開口８７を介して貯溜部３５内に差し込み、ロック構造６９を取付座４９に係合させる。これにより、検知装置４０とホルダー４７とを、装着窓４１に対して抜け外れ不能に固定保持させることができる。より具体的には、ロック構造６９を構成する上下の係止爪８３・８３が近付く方向に両ロックアーム８２・８２を撓み変形させたうえで、上下の取付座４９・４９の装着溝６２・６２に係止爪８３・８３を位置合わせし、両ロックアーム８２・８２の撓み変形状態を解除して、両ロックアーム８２・８２の弾性力によりホルダー４７を取付座４９に固定保持させる。かかる固定保持状態においては、シール部材４８の外面にホルダー４７のベース部６７が押し付けられるので、装着窓４１から機械室４側へ氷片や水が漏れることを確実に防止できる。また、かかる固定保持状態においては、挟持壁８４・８４で取付座４９のリブ６４を挟持して、ホルダー４７が取付座４９に対して前後方向に遊動することを規制できる。 Next, in a state where the sealing member 48 is temporarily fixed to the opening edge of the mounting window 41, the detection device 40 is moved from the outer surface side of the storage portion 35 into the storage portion 35 through the mounting window 41 and the central opening 87 of the sealing member 48. The lock structure 69 is engaged with the mounting seat 49. Thereby, the detection device 40 and the holder 47 can be fixedly held so as not to be detached from the mounting window 41. More specifically, after the upper and lower locking arms 82 and 82 are bent and deformed in the direction in which the upper and lower locking claws 83 and 83 constituting the lock structure 69 approach, the mounting grooves 62 and 49 of the upper and lower mounting seats 49 and 49 are deformed. The locking claws 83 and 83 are aligned with 62, the bending deformation state of both lock arms 82 and 82 is released, and the holder 47 is fixedly held on the mounting seat 49 by the elastic force of both lock arms 82 and 82. In such a fixed holding state, since the base portion 67 of the holder 47 is pressed against the outer surface of the seal member 48, it is possible to reliably prevent ice pieces and water from leaking from the mounting window 41 to the machine room 4 side. Further, in such a fixed holding state, the ribs 64 of the mounting seat 49 can be clamped by the clamping walls 84 and 84 to restrict the holder 47 from moving forward and backward relative to the mounting seat 49.

ベース部６７の通孔９１からリード線９０から引き出された状態で、ホルダー４７の取付座４９に対する固定保持作業が行われるので、リード線９０を貯溜部３５内から引き出すための特別な作業を完全に廃して、より簡単に検知装置４０の貯溜部３５への取付作業を進めることができる。最後に、半割状のカバー９４を蓋合わせ状にシュート２１の全体に被せ付ける。以上のように、この取付構造によれば、検知装置４０の取付作業の全てを、シュート２１の外側から進めることができる。 Since the work of fixing and holding the holder 47 with respect to the mounting seat 49 is performed while being pulled out from the lead wire 90 from the through hole 91 of the base portion 67, a special work for pulling out the lead wire 90 from the storage portion 35 is completely performed. Therefore, the attaching operation of the detection device 40 to the reservoir 35 can be more easily advanced. Finally, the half-shaped cover 94 is put on the entire chute 21 so as to cover each other. As described above, according to this mounting structure, all the mounting work of the detection device 40 can be advanced from the outside of the chute 21.

メンテナンス等により、例えば検知装置４０の交換が必要となった場合には、先と逆の手順を取ることで、検知装置４０を貯溜部３５から取り外すことができる。まず、カバー９４をシュート２１から取り外す。次に、上下のロックアーム８２・８２のＵ字部分を掴んで、上下の係止爪８３・８３が近付く方向に両ロックアーム８２・８２を撓み変形させて、装着溝６２・６２から係止爪８３・８３の係止状態を解除したうえで、ホルダー４７を手前側に引く。これにより、ホルダー４７と共に検知装置４０を装着窓４１を介して貯溜部３５から抜き出すことができる。このとき、検知装置４０と共にリード線９０をシュート２１の外側に引き出すことができる。検知装置４０の交換終了後は、検知装置４０のホルダー４７への保持、ホルダー４７のシュート２１の取付座４９への固定保持、カバー９４の装着の手順を取ることで、検知装置４０の貯溜部３５への取付作業は終了する。 For example, when the detection device 40 needs to be replaced due to maintenance or the like, the detection device 40 can be removed from the storage unit 35 by taking the reverse procedure. First, the cover 94 is removed from the chute 21. Next, the U-shaped portions of the upper and lower lock arms 82 and 82 are gripped, and both the lock arms 82 and 82 are bent and deformed in the direction in which the upper and lower locking claws 83 and 83 approach each other, and are locked from the mounting grooves 62 and 62. After releasing the locking state of the claws 83, the holder 47 is pulled to the near side. As a result, the detection device 40 together with the holder 47 can be extracted from the storage portion 35 via the mounting window 41. At this time, the lead wire 90 can be pulled out of the chute 21 together with the detection device 40. After the replacement of the detection device 40, the storage unit of the detection device 40 is obtained by taking the procedures of holding the detection device 40 to the holder 47, fixing the chute 21 of the holder 47 to the mounting seat 49, and attaching the cover 94. The attachment work to 35 is completed.

以上のように、この取付構造によれば、作業者はシュート２１の外面側から検知装置４０の取付作業、或いは検知装置４０の取り外し作業を行うことができるので、シュート２１の内面側における一切の作業を廃することができる。従って、検知装置４０のメンテナンス作業を作業効率良く、より容易に進めることができる。 As described above, according to this mounting structure, the operator can perform the mounting operation of the detection device 40 or the removal operation of the detection device 40 from the outer surface side of the chute 21, so that any operation on the inner surface side of the chute 21 can be performed. Work can be abolished. Accordingly, the maintenance work of the detection device 40 can be performed more easily and efficiently.

ホルダー４７のベース部６７にリード線９０を導出するための通孔９１を形成して、該通孔９１を介してリード線９０をシュート２１の外部へ引き出すようにしたので、取付構造による脱着作業時において、リード線９０を引き出すための専用の配線作業は不要となり、この点でも検知装置４０のメンテナンス作業を作業効率良く進めることができる。また、取付状態におけるリード線９０の余裕長さが、検知装置４０及びホルダー４７の装着窓４１からの抜き出し作業時に支障が生じない程度に大きく設定されるため、検知装置を装着窓４１から大きく引き出すことが可能となり、この点でもメンテナンス作業等を作業効率良く進めることができる。 A through hole 91 for leading out the lead wire 90 is formed in the base portion 67 of the holder 47, and the lead wire 90 is drawn out of the chute 21 through the through hole 91. At this time, a dedicated wiring work for pulling out the lead wire 90 is not necessary, and the maintenance work of the detection device 40 can also be efficiently performed in this respect. Further, since the margin length of the lead wire 90 in the mounted state is set large enough to prevent troubles when the detection device 40 and the holder 47 are extracted from the attachment window 41, the detection device is pulled out from the attachment window 41 greatly. In this respect, maintenance work and the like can be carried out efficiently.

この取付構造によれば、シュート２１内での作業を廃することができるので、取付作業やメンテナンス作業時にシュート２１内が汚染されるおそれが少なく、シュート２１内の洗浄などの余分な手間が不要となる利点がある。ビスや螺子等の締結部品を一切用いることなく、検知装置４０をシュート２１に脱着可能に取り付けることができるので、ビスや螺子等の締結部材の貯氷室５内への落下のおそれがなく、当該取付構造が適用された製氷機の信頼性向上に貢献できる。 According to this mounting structure, since the work in the chute 21 can be eliminated, the chute 21 is less likely to be contaminated during the mounting work and the maintenance work, and unnecessary work such as cleaning the chute 21 is unnecessary. There is an advantage to become. Since the detection device 40 can be detachably attached to the chute 21 without using any fastening parts such as screws and screws, there is no risk of the fastening members such as screws and screws falling into the ice storage chamber 5. Contributes to improving the reliability of ice machines to which the mounting structure is applied.
