Description

【０００１】
【発明の属する技術分野】
この発明は、断熱箱体の断熱体配設構造に関し、更に詳細には、例えば貯氷庫の内部に配設した製氷ユニット等から導出する各種管体やリード線等を庫外に引出すための凹部に収納配置される断熱体の配設構造に関するものである。
【０００２】
【従来の技術】
図８に示す如く、所要形状の氷塊を自動的に製造する自動製氷機１０は、前方および上方に開放する断熱箱体としての貯氷庫１２と、該貯氷庫１２の前部に開閉可能に配設される扉１４と、該貯氷庫１２の上部に着脱可能に配設される天板１６とから基本的に構成される。なお、貯氷庫１２の頂部に水平に配置した取付枠(図示せず)に懸吊した製氷ユニット(図示せず)が、庫内上方に臨むと共に、該製氷ユニットの下方に排水皿１８が配設される。
【０００３】
前記貯氷庫１２の後壁２０には、図９に示す如く、正面から視て右側に偏った位置に、上方に開放すると共に庫内と庫外とを連通する凹部２２が形成され、該凹部２２を介して前記製氷ユニットから導出するリード線や冷媒管(管体)等(何れも図示せず)が庫外に引出されるよう構成される。またこの凹部２２には、図１０および図１１に示す断熱体２４が収納配置され、庫内の断熱性を確保するようになっている。なお、断熱体２４には、リード線や冷媒管等の挿通を許容する複数の通孔２４ａが形成してある。
【０００４】
【発明が解決しようとする課題】
前記断熱体２４の外形は、前記凹部２２の内部形状と略同一に設定されて、該断熱体２４が凹部２２内にすき間なく収納配置されるものであるが、このとき断熱体２４の内外方向(前後方向)への位置規制はなされていない。このため、貯氷庫１２が外部から衝撃等を受けた際に断熱体２４が位置ずれし易く、凹部２２から断熱体２４が脱落するおそれがあった。
【０００５】
【発明の目的】
本発明は、前述した従来の技術に内在している前記欠点に鑑み、これを好適に解決するべく提案されたものであって、断熱体を確実に位置決め保持し得る断熱箱体の断熱体配設構造を提供することを目的とする。
【０００６】
【課題を解決するための手段】
前記課題を克服し、所期の目的を好適に達成するため、本発明に係る断熱箱体の断熱体配設構造は、
内外に連通する凹部が壁の上部に設けられ、各種管体が凹部を介して内側から外側に引出されると共に、該凹部には各種管体の挿通を許容する断熱体が収納配置される断熱箱体において、
前記凹部における内外の端縁部に、前記断熱体の収納側に延出する内フランジと外フランジが形成され、
前記凹部に収納配置した断熱体を、前記内フランジと外フランジとで位置決めするよう構成したことを特徴とする。
【０００７】
【発明の実施の形態】
次に、本発明に係る断熱箱体の断熱体配設構造につき、好適な実施例を挙げて、添付図面を参照しながら以下説明する。なお、実施例に係る断熱箱体としての貯氷庫が採用される自動製氷機自体の構成は、従来の技術で説明したものと同一であるので、その詳細説明は省略する。
【０００８】
図３は、実施例に係る貯氷庫３０の本体３２を示すものであって、該本体３２は、前方および上方に開放する箱形に形成される。そして、本体３２の両側壁３４,３４、底壁３６および後壁(壁)３８の各外部に、サイドパネル、ボトムパネルおよびリアパネル４０(図６に一部図示)を配設すると共に、各壁３４,３４,３６,３８と各パネル４０との間に画成される空間に発泡断熱材４２を充填することで、当該貯氷庫３０は断熱構造とされている。
【０００９】
前記本体３２における後壁３８の上部には、図３において右側に偏った位置に、上方に開放すると共に庫内と庫外とを連通する凹部４４が形成され、該凹部４４を介して前記製氷ユニットから導出するリード線や冷媒管等が外方(内側から外側)に引出されるよう構成される。この凹部４４には、図１および図２に示す如く、該凹部４４の内部形状と略同一形状に形成された弾性変形可能な例えば発泡材等からなる断熱体４６が着脱可能に収納配置され、凹部４４の部分において庫内と庫外との連通を遮断して断熱性を確保するようになっている。なお、断熱体４６には、前記リード線や冷媒管の挿通を許容する複数の通孔４６ａが形成され、リード線や冷媒管は該通孔４６ａを介して庫外に引出される。
【００１０】
また、前記凹部４４の庫内側の端縁部に、図３および図５に示す如く、断熱体４６の収納側に所定長さで延出する内フランジ４８が形成されると共に、該凹部４４の庫外側の端縁部にも、図４および図５に示す如く、同じく断熱体４６の収納側に所定長さで延出する外フランジ５０が形成されている。ここで、前記断熱体４６の前後厚み寸法は、内フランジ４８と外フランジ５０との離間間隔より大きく設定されると共に、該断熱体４６の左右幅寸法は、凹部４４の内部左右幅寸法より大きく設定される。すなわち、断熱体４６を凹部４４に収納配置した際には、該断熱体４６の外表面が弾性復元力によって両フランジ４８,５０および凹部４４の内側面に密着し、断熱体４６の前後方向(内外方向)の移動が両フランジ４８,５０により規制されると共に、左右方向の移動が凹部４４の内側壁により規制され、該断熱体４６は外部からの衝撃により容易に位置ずれしないよう構成される。なお、図１および図２に示す如く、凹部４４の両内側壁の上部から後壁３８の上面に亘る部分に、該凹部４４に収納された断熱体４６の両側面上部を露出させる切欠部５８,５８が形成されており、両切欠部５８,５８に露出する断熱体４６の両側面を手指等で把持して容易に取出し得るよう構成してある。
【００１１】
実施例の貯氷庫３０では、ゴムや合成樹脂等を材質として、前記凹部４４の内部形状と略同一形状に形成された板状のカバー体５２が、図２に示す如く、前記内フランジ４８と断熱体４６との間に挿入され、断熱体４６が庫内側に露出しないようになっている。なお、このカバー体５２には、断熱体４６に形成された通孔４６ａと対応する位置に通孔５２ａが形成され、前後に整列する通孔５２ａ,４６ａにリード線や冷媒管が挿通されるよう構成してある。また、内フランジ４８の延出端縁部(開放端)とカバー体５２との当接部は、コーキング処理が施される。
【００１２】
前記後壁３８には、図４および図６に示す如く、前記外フランジ５０から連続して下および側方に所定長さで延出する延出部５４が形成され、この延出部５４に前記リアパネル４０が当接するよう構成されている。すなわち、後壁３８にリアパネル４０を配設した際に、該延出部５４がリアパネル４０に当接することで当接面積が多くなり、後壁３８とリアパネル４０との間に画成された空間に発泡断熱材４２を充填する際の発泡漏れを有効に防止し得るようになっている。なお、リアパネル４０には、後壁３８の凹部４４と対応する位置に、前記リード線や冷媒管の挿通を許容する逃がし部４０ａが形成してある。
【００１３】
【実施例の作用】
次に、実施例に係る断熱体配設構造の作用につき説明する。前記本体３２における各壁３４,３４,３６,３８の外部に、各パネル４０を取付けた後、各壁３４,３４,３６,３８と各パネル４０との間に画成される空間に発泡断熱材４２を充填することで、断熱構造の貯氷庫３０が得られる。このとき、後壁３８の外側に取付けられるリアパネル４０は、図６に示す如く、前記外フランジ５０に連設される延出部５４に当接してシール性が向上しているから、前記空間に充填される発泡断熱材４２がその当接部から漏れるのは好適に防止される。
【００１４】
前記貯氷庫３０に製氷ユニットを配設する際には、前記カバー体５２および断熱体４６の通孔５２ａ,４６ａにリード線や冷媒管を挿通した状態で、該カバー体５２および断熱体４６を前記後壁３８に形成した凹部４４に収納配置する。このとき、断熱体４６の前後方向の移動が前記内フランジ４８および外フランジ５０により規制されるから、該断熱体４６は外部からの衝撃により容易に位置ずれして凹部４４から脱落しない。また内フランジ４８と断熱体４６との間に挿入されるカバー体５２は、断熱体４６の弾性復元力によって内フランジ４８に押付けられるから、該カバー体５２が位置ずれするのも抑制される。しかも、図２に示す如く、このカバー体５２により断熱体４６は庫内側に露出しないようになっているから、断熱体４６の経年劣化により発生するカス等が庫内に入って不衛生となるのは防止される。更には、このカバー体５２により、庫内の水分が断熱体４６に接触するのを防ぎ、該断熱体４６の劣化を抑制することもできる。なお、凹部４４に収納されている断熱体４６の両側面上部は、図２に示すように前記切欠部５８,５８に露出しているから、この部分を把持して断熱体４６を凹部４４から簡単に取出すことができる。
【００１５】
ここで、従来の断熱体配設構造(図１０参照)では、ＮＳＦ規格に適合させて海外向けの製品とする場合は、前記断熱体を庫内に露出しないようにするため、合成樹脂等の材料により後方に開放する箱状に形成したカバー体に該断熱体を配設した状態で、該カバー体を凹部に収納配置している。しかるに、この場合のカバー体の形状は複雑となるため、加工コストが嵩む問題を招いていたが、実施例ではカバー体５２の構成は簡単で加工の容易な板状とし得るから、コストを低減することができる。しかも、国内向けと海外向けとでの部品の共通化を図ることが容易となる利点もある。
【００１６】
【別実施例】
図７は、別実施例に係る断熱体配設構造が採用される貯氷庫の本体を示すものであって、基本的な構成は前述した実施例と同一であって、前記内フランジ４８に切欠５６が形成されている点のみが異なる。すなわち、この切欠５６は、前記凹部４４の底面まで達する深さに設定され、該凹部４４内で生じた結露水(水)や外部で生じて流入した結露水(水)を庫内側に排出するべく機能する。従って、凹部４４には結露水が溜まることはなく、前記断熱体４６が劣化するのを抑制し得ると共に常に衛生的に保つことができる。
【００１７】
前述した実施例では、断熱箱体を自動製氷機に使用する貯氷庫の場合で説明したが、本願はこれに限定されるものでなく、内側から外側へ各種の管体を引出すための凹部や断熱体が設けられるものであれば、例えば冷蔵庫や冷凍庫等を構成する断熱箱体であってもよい。また実施例では、凹部に断熱体とカバー体とを収納配置した場合で説明したが、カバー体は必要に応じて採用すればよく、断熱体のみを凹部に収納配置する構成とすることもできる。更に、凹部に形成されるフランジに関しては、凹部の端縁部における全体に亘って連続的に形成されていなくてもよく、例えば所定間隔で櫛歯状に形成されたものであってもよい。更にまた、凹部が形成される壁は後壁に限らず、側壁であってもよい。
【００１８】
【発明の効果】
以上説明した如く、本発明に係る断熱箱体の断熱体配設構造では、凹部の内外の端縁部にフランジを形成し、該凹部に収納配置される断熱体の移動を両フランジで規制するよう構成したから、外部からの衝撃等によって断熱体が凹部から脱落するのを防止し得る。また、凹部内の水を内フランジに形成した切欠を介して庫内側に排出するよう構成したので、凹部内を常に衛生的に保つことができると共に、断熱体が溜まった水により劣化するのを抑制し得る。

DETAILED DESCRIPTION OF THE INVENTION
Next, the heat insulating body arrangement structure of the heat insulating box according to the present invention will be described below with reference to the accompanying drawings by citing preferred embodiments. In addition, since the structure of the automatic ice making machine itself which employ | adopts the ice storage as a heat insulation box which concerns on an Example is the same as what was demonstrated by the prior art, the detailed description is abbreviate | omitted.
[0008]
FIG. 3 shows a main body 32 of the ice storage 30 according to the embodiment, and the main body 32 is formed in a box shape that opens forward and upward. A side panel, a bottom panel, and a rear panel 40 (partially shown in FIG. 6) are disposed outside the both side walls 34, 34, the bottom wall 36, and the rear wall (wall) 38 of the main body 32, and each wall. The ice storage 30 has a heat insulating structure by filling the space defined between the panels 34, 34, 36, and 38 and the panels 40 with the foam heat insulating material 42.
[0009]
In the upper part of the rear wall 38 in the main body 32, a concave portion 44 is formed at a position biased to the right in FIG. 3 and opens upward and communicates the inside and the outside of the warehouse. A lead wire, a refrigerant pipe and the like led out from the unit are configured to be drawn outward (from inside to outside). As shown in FIGS. 1 and 2, in this recess 44, a heat insulating body 46 made of an elastically deformable material such as a foam material formed in substantially the same shape as the inner shape of the recess 44 is detachably accommodated. In the portion of the concave portion 44, the communication between the inside and the outside of the warehouse is cut off to ensure heat insulation. The heat insulator 46 is formed with a plurality of through holes 46a that allow the lead wires and the refrigerant pipes to pass therethrough, and the lead wires and the refrigerant pipes are drawn out of the chamber through the through holes 46a.
[0010]
Further, as shown in FIGS. 3 and 5, an inner flange 48 extending at a predetermined length is formed on the storage side of the heat insulating body 46 at the end edge inside the storage of the recess 44. As shown in FIGS. 4 and 5, an outer flange 50 extending to a predetermined length on the housing side of the heat insulating body 46 is also formed on the outer edge of the warehouse. Here, the front-rear thickness dimension of the heat insulating body 46 is set to be larger than the separation interval between the inner flange 48 and the outer flange 50, and the left-right width dimension of the heat insulating body 46 is larger than the inner left-right width dimension of the recess 44. Is set. That is, when the heat insulator 46 is housed and disposed in the recess 44, the outer surface of the heat insulator 46 is brought into close contact with both flanges 48 and 50 and the inner surface of the recess 44 by the elastic restoring force. The movement in the inner and outer directions is regulated by both flanges 48 and 50, and the movement in the left and right direction is regulated by the inner wall of the recess 44, so that the heat insulator 46 is not easily displaced by an external impact. . As shown in FIGS. 1 and 2, notches 58 that expose the upper portions of both side surfaces of the heat insulator 46 accommodated in the recess 44 in the portion from the upper part of both inner side walls of the recess 44 to the upper surface of the rear wall 38. , 58 are formed so that both sides of the heat insulating body 46 exposed at the notches 58, 58 can be easily taken out by gripping them with fingers or the like.
[0011]
In the ice storage 30 according to the embodiment, a plate-like cover body 52 made of rubber, synthetic resin, or the like and formed in substantially the same shape as the inner shape of the recess 44 is connected to the inner flange 48 as shown in FIG. It is inserted between the heat insulators 46 so that the heat insulators 46 are not exposed to the inside of the cabinet. The cover body 52 is formed with a through hole 52a at a position corresponding to the through hole 46a formed in the heat insulating body 46, and a lead wire or a refrigerant pipe is inserted into the through holes 52a and 46a aligned in the front-rear direction. It is configured as follows. Further, the contact portion between the extended edge portion (open end) of the inner flange 48 and the cover body 52 is subjected to coking processing.
[0012]
As shown in FIGS. 4 and 6, the rear wall 38 is formed with an extending portion 54 that continuously extends from the outer flange 50 downward and laterally to a predetermined length. The rear panel 40 is configured to abut. That is, when the rear panel 40 is disposed on the rear wall 38, the extended area 54 comes into contact with the rear panel 40 to increase the contact area, and the space defined between the rear wall 38 and the rear panel 40. It is possible to effectively prevent foam leakage when the foam insulation material 42 is filled. The rear panel 40 is formed with a relief portion 40 a that allows the lead wire and the refrigerant pipe to be inserted at a position corresponding to the concave portion 44 of the rear wall 38.
[0013]
[Effect of the embodiment]
Next, the operation of the heat insulator arrangement structure according to the embodiment will be described. After each panel 40 is attached to the outside of each wall 34, 34, 36, 38 in the main body 32, foam insulation is formed in a space defined between each wall 34, 34, 36, 38 and each panel 40. By filling the material 42, the ice storage 30 having a heat insulating structure is obtained. At this time, as shown in FIG. 6, the rear panel 40 attached to the outside of the rear wall 38 is in contact with the extending portion 54 provided continuously to the outer flange 50 to improve the sealing performance. The foamed heat insulating material 42 to be filled is preferably prevented from leaking from the contact portion.
[0014]
When the ice making unit is disposed in the ice storage 30, the cover body 52 and the heat insulator 46 are placed in a state where lead wires or refrigerant pipes are inserted into the through holes 52a, 46a of the cover body 52 and the heat insulator 46. It is stored and disposed in a recess 44 formed in the rear wall 38. At this time, since the movement of the heat insulating body 46 in the front-rear direction is restricted by the inner flange 48 and the outer flange 50, the heat insulating body 46 is easily displaced by an external impact and does not fall off the recess 44. Further, since the cover body 52 inserted between the inner flange 48 and the heat insulating body 46 is pressed against the inner flange 48 by the elastic restoring force of the heat insulating body 46, the displacement of the cover body 52 is also suppressed. In addition, as shown in FIG. 2, since the heat insulating body 46 is not exposed to the inside of the cabinet by the cover body 52, debris and the like generated due to aging of the heat insulating body 46 enter the warehouse and become unsanitary. Is prevented. Furthermore, the cover body 52 can prevent moisture in the cabinet from coming into contact with the heat insulating body 46, and can suppress deterioration of the heat insulating body 46. The upper portions of both side surfaces of the heat insulator 46 accommodated in the recess 44 are exposed at the notches 58 and 58 as shown in FIG. Easy to take out.
[0015]
Here, in the conventional heat insulator arrangement structure (see FIG. 10), in order to prevent the heat insulator from being exposed in the cabinet when conforming to the NSF standard and being a product for overseas use, The cover body is housed and disposed in the recess in a state in which the heat insulator is disposed on a cover body that is formed in a box shape that is opened rearward by a material. However, since the shape of the cover body in this case is complicated, there has been a problem that the processing cost increases. However, in the embodiment, the configuration of the cover body 52 can be a simple and easy-to-process plate shape, thus reducing the cost. can do. In addition, there is an advantage that it is easy to share parts for domestic and overseas use.
[0016]
[Another example]
FIG. 7 shows a main body of an ice storage in which a heat insulator arrangement structure according to another embodiment is adopted. The basic structure is the same as that of the above-described embodiment, and the inner flange 48 is notched. The only difference is that 56 is formed. That is, the notch 56 is set to a depth that reaches the bottom surface of the concave portion 44, and discharges the condensed water (water) generated in the concave portion 44 and the condensed water (water) that flows in and flows outside. Functions as much as possible. Therefore, the condensate does not accumulate in the recess 44, and the heat insulator 46 can be prevented from deteriorating and can be kept hygienic at all times.
[0017]
In the embodiment described above, the case of an ice storage that uses a heat insulating box for an automatic ice making machine has been described. However, the present application is not limited to this, and a recess for drawing various types of tubes from the inside to the outside can be used. As long as a heat insulator is provided, it may be a heat insulating box constituting a refrigerator, a freezer, or the like. Further, in the embodiments, the case where the heat insulating body and the cover body are accommodated in the concave portion has been described, but the cover body may be adopted as necessary, and only the heat insulating body may be accommodated in the concave portion. . Furthermore, the flange formed in the concave portion may not be formed continuously over the entire edge portion of the concave portion, and may be formed, for example, in a comb shape at a predetermined interval. Furthermore, the wall in which the recess is formed is not limited to the rear wall but may be a side wall.
[0018]
【The invention's effect】
As described above, in the heat insulating body arrangement structure of the heat insulating box according to the present invention, flanges are formed at the inner and outer edge portions of the concave portion, and the movement of the heat insulating body accommodated in the concave portion is regulated by both flanges. Since it comprised in this way, it can prevent that a heat insulating body falls off from a recessed part by the impact from the outside. In addition, since the water in the concave portion is configured to be discharged to the inside of the warehouse through the notch formed in the inner flange, the inside of the concave portion can be always kept hygienic and the insulator is deteriorated by the accumulated water. Can be suppressed.
