Description

【0001】
【発明の属する技術分野】
本発明は、本体背面に冷却ユニットからのドレン水を受ける蒸発皿を設け、凝縮器用送風機により後方に空気を吐出して成る冷却貯蔵庫に関するものである。
【0002】
【従来の技術】
従来この種の冷却貯蔵庫のドレン水蒸発装置は、例えば特開平5−141848号公報に示される如く蒸発皿を下部の機械室に設置し、高温冷媒配管の熱を利用して蒸発皿のドレン水を蒸発させる方法が採られている。係る構成であるため蒸発皿自体の納出が容易に行え、利便性の高いものである。
【0003】
また、この他にも他の種の冷却貯蔵庫として、機械室を本体の天面に構成した冷却貯蔵庫がある。その場合には、蒸発皿は本体背面に設置される場合がある。
【0004】
【発明が解決しようとする課題】
しかしながら、機械室が本体の天面に設置されている冷却貯蔵庫において、蒸発皿は本体背面に設けられている場合に、係る冷却貯蔵庫を厨房などの壁面に設置された状態で掃除又は交換などのメンテナンスを行うことが困難であるという問題が生じた。
【0005】
また、係る冷却貯蔵庫が設置場所の壁面に冷却貯蔵庫本体が押し付けられると通風性能が低下することにより、ドレン水処理(蒸発)性能低下する問題が生じた。
【0006】
本発明は、係る従来の技術的課題を解決するために成されたものであり、厨房などに設置された状態での蒸発皿の掃除又は交換などのメンテナンスを支障無く行うことができると共に、通風性能の低下に伴うドレン水処理(蒸発)性能の低下を未然に回避することができる冷却貯蔵庫を提供するものである。
【0007】
【課題を解決するための手段】
本発明の冷却貯蔵庫は、本体天面に機械室を構成し、冷却装置の凝縮ユニットを前記機械室に設置すると共に、前記本体背面には前記冷却装置の冷却ユニットからのドレン水を受ける蒸発皿を設け、前記凝縮ユニットを構成する凝縮器用送風機により後方に空気を吐出して成るものであって、上端において前記機械室に連通し、下端において外部に開放するダクトを前記本体背面に構成する風向板と、前記蒸発皿内に設けられた親水性の蒸発部材とを備え、前記蒸発皿を前記ダクト内に配設すると共に、前記蒸発皿に対応する位置の前記風向板両側部には、前記蒸発部材が通過可能な開口を形成し、前記風向板には蒸発皿をヒータの位置する本体背面に押圧する突起を形成したものである。
【0008】
本発明によれば、本体天面に機械室を構成し、冷却装置の凝縮ユニットを機械室に設置すると共に、本体背面には冷却装置の冷却ユニットからのドレン水を受ける蒸発皿を設け、凝縮ユニットを構成する凝縮器用送風機により後方に空気を吐出して成る冷却貯蔵庫において、上端において機械室に連通し、下端において外部に開放するダクトを本体背面に構成する風向板を設けると共に、蒸発皿をダクト内に配設したので、凝縮器用送風機から吐出された温かい空気はダクト内に入り、蒸発皿周囲を通過して外部に排出されるようになる。
【0009】
そして、蒸発皿内には親水性の蒸発部材を設けているので、蒸発皿内のドレン水を迅速に蒸発処理することができるようになる。
【0010】
特に、蒸発皿に対応する位置の風向板両側部には、蒸発部材が通過可能な開口を形成したので、この開口から蒸発部材の交換・点検などのメンテナンスを行うことができるようになる。また、開口は両側に形成されているので、冷却貯蔵庫が設置された場所の左右何れかに回り込めればメンテナンスを行うことができるようになり、保守作業性が著しく改善されるものである。
【0016】
更に、風向板には蒸発皿を本体背面に押圧する突起を形成したので、蒸発皿とヒータとの熱交換を効率良く行わせ、ドレン水の蒸発能力を一層向上させることができるようになるものである。
【0017】
請求項2の冷却貯蔵庫は請求項1の発明に加えて、蒸発皿は本体に係脱自在に取り付けられると共に、本体に取り付けられた状態で前記蒸発皿は風向板下端より下方に突出するものである。
【0018】
請求項2の発明によれば、上記発明に加えて蒸発皿を本体に係脱自在に取り付けると共に、本体に取り付けられた状態で蒸発皿は風向板下端より下方に突出するよう構成したので、蒸発皿を風向板下方からダクト内に挿入して容易に取り付け、取り外しを行うことができるようになる。これにより、蒸発皿のメンテナンス作業性を向上させることができるようになるものである。
【0023】
【発明の実施の形態】
次に、図面に基づき本発明の実施形態を詳述する。図1は本発明の実施例としての冷却貯蔵庫1の斜視図、図2は冷却貯蔵庫1の断熱扉5を除く正面図、図3は冷却貯蔵庫1の天板を除いた蒸発部材64を設置する時の背面斜視図、図4は冷却貯蔵庫1の蒸発装置部分の拡大側面図、図5は冷却貯蔵庫1の天板装着時の背面斜視図、図6は冷却貯蔵庫1上部の側面図である。
【0024】
実施例の冷却貯蔵庫1は、カートン入りの缶飲料などを冷却保存するための業務用冷蔵庫であり、前面に開口する矩形状の断熱箱体3により本体が構成されている。この断熱箱体3は前面に開口するステンレス製の外箱54と内箱24間に発泡ポリウレタン断熱材55を充填して構成されており、この断熱箱体3内に前面に開口2を有した貯蔵室4が構成されると共に、この開口2は断熱箱体3の右前面に回動自在に枢支された断熱扉5にて開閉自在に閉塞されている。
【0025】
断熱箱体3の天壁3Aには図示しない矩形状の窓孔が形成されており、この窓孔を上から閉塞するかたちで断熱板7が取り付けられる。この断熱板7の下面には冷却装置の冷却ユニットを構成する冷却器10と、その右側には送風機11が取り付けられており、これらの冷却器10及び送風機11は貯蔵室4内上部に位置している。
【0026】
冷却器10の下側には露受板12が配置されると共に、これらの下方には仕切板13が設けられ、送風機11に対応する仕切板13の右側には吸込口14が、また、仕切板13の左側には吐出口15が形成されている。更に、断熱箱体3の左右側壁3B、3Cの内面には、ダクト板21、21が取り付けられており、各ダクト板21、21と側壁3B、3C間に上下のダクト21D、21Dが構成され、更に各ダクト板21、21には、貯蔵室4内に架設されたそれぞれの棚22・・に冷気を循環させるための孔23・・が形成されている。
【0027】
そして、前記圧縮機16及び送風機11が運転されると、冷却器10が冷却作用を発揮し、この冷却器10と熱交換した冷気は吐出口15から左側のダクト21Dに入り、そこを図2中矢印の如く流下しながら左側のダクト板21の各孔23・・・より貯蔵室4内に吹き出される。
【0028】
次に、貯蔵室4内を循環した後、右側のダクト板21の孔23・・から右側のダクト21D内に流通し、そこを上昇して吸込口14から吸引される。これによって、貯蔵室4内は所定の冷蔵温度に維持される。
【0029】
尚、係る実施例において、図2に示す如く前記貯蔵室4内に架設された最下段の棚22と貯蔵室4の底面との間に所定の間隔を構成されており、この貯蔵室4の底面にはカート30が収納されている。そして、このカート30上に例えば缶ジュース等を梱包した段ボールを二段重ねで載置した場合でも、当該段ボールがカート30の直上の棚22(最下段の棚22)に当接しないように構成されている。
【0030】
係るカート30は、背方の内箱24と左右のダクト板21、21により囲繞される空間より一回り小さい平面寸法の矩形基台31により構成され、この基台31の下面四隅にはそれぞれキャスター32・・・が取り付けられている。そして、カート30はこれらのキャスター32・・・が貯蔵室4の底面を滑動することにより、前後方向に引き出し自在とされているものである。また、基台31の下面前端部には、基台31を前方に引き出し又は後方に押し入れるための略コ字状のハンドル33が取り付けられている。
【0031】
そして、図1に示す如く前記冷却貯蔵庫1の断熱箱体3の底壁の前面には、カート30の案内板となるスロープ43が図示しないボルトによって取り付けられている。このスロープ43は開口2部分から連続して前方に延在しており、先端から後端に向けて徐々に上昇する傾斜面とされている。
【0032】
一方、前記断熱板7の上面には前記冷却装置の凝縮ユニットを構成する圧縮機16、凝縮器17及び凝縮器用送風機18、コントロールボックス19などが設置され、これらは断熱箱体3の天壁3A上(天井)に位置する。
【0033】
これら凝縮ユニットの周囲にはパネル20が取り付けられて隠蔽され、断熱箱体3の天壁3A上に機械室8を構成すると共に、パネル20の前面の右側からは前記コントロールボックス19が前方に臨む。即ち、前記凝縮ユニットはこの機械室8内に設置される。
【0034】
次に、図3乃至図6を参照して前記露受板12において受容したドレン水の蒸発構造について説明する。前記露受板12は貯蔵室4内の奥面に向かって下向きに徐々に傾斜しており、この露受板12の最下端には、ドレンパイプ60が設けられている。このドレンパイプ60は貯蔵庫1本体の背面に連通しており、ドレンパイプ60の露受板12と反対側の端部にはドレン水を受容するための蒸発皿61が貯蔵庫1本体背面に設置されている。
【0035】
係る蒸発皿61は上面に開口を有した矩形状の容器であり、貯蔵庫1本体背面に接触していると共に当接している面(当接面)61Aは他の三方の側面よりも上方に向かって、長く延在している。
【0036】
また、貯蔵庫1本体背面には前記蒸発皿61を着脱自在に取り付けるため取付具62、62が設置されており、この蒸発皿61の当接面61Aの上方には、前記取付具62に取り付けるための穴63、63が形成されている。
【0037】
そして、蒸発皿61内には蒸発部材64が載置されている。係る蒸発部材64はユニベックス(商品名)SB等親水性板から成る帯状体で、ポリエステル繊維などの不織布を基材とし、この基材に微粒子状のフェノールを熱硬化させて固着材とし、更に親水性を付与して毛細管現象を得るためにアルコール系の溶剤に浸した後、乾燥させたものであり、繊維質である関係上、伸縮自在に折り曲げ可能でありしかも折り曲げに対して反発力を有するものである。これによって、蒸発皿61内のドレン水は蒸発部材64に浸漬されることになる。
【0038】
次に、図4を参照して、貯蔵庫1本体背面の最外側に取り付けられる蒸発皿カバーとしての風向板53について説明する。係る風向板53は、貯蔵庫1背面の上端部から取り付けられており、前記機械室8と連通し、下端において外部に開放するダクト65を形成している。また、風向板53は、風向板53上部に形成された傾斜部53A、貯蔵庫1背面と所定の間隔を存して背面と平行に形成された水平部53B、両側面に形成された開口部53C及び下端の開口部53Dにより構成されている。
【0039】
係る傾斜部53Aは、前記水平部53Bから連続して上方に延在しており、先端から水平部53Bに向けて徐々に上昇する傾斜面とされている。そして、係る水平部53Bは前記蒸発皿61よりも少許上方で終結しており、係る終結部では開口部53Dと連続している。係る構造より、蒸発皿61を取り外す際に、蒸発皿61の底部を上方向に持ち上げることによって、蒸発皿61を容易に取り外すことができる。
【0040】
また、風向板53及び蒸発皿61を貯蔵庫1に取付た際に、蒸発皿61に載置された蒸発部材64が係る風向板53の側面から取り出せる位置であると共に、風向板53の両側面には蒸発部材64の縦の寸法よりも大きい、即ち、蒸発部材64が通過可能な寸法の矩形状開口部53C、53Cが形成されている。
【0041】
更に、蒸発部材64及び蒸発皿61を取付た際に、蒸発部材64と対向する位置である風向板53の水平部53Bの下部には、それぞれ図3に示す如き複数の方形状の長孔66・・が横方向に所定間隔で形成されており、ダクト65から流通した空気を排出している。
【0042】
また、前記蒸発皿61と当接している断熱箱体3の背面には、ヒータ67が設けられており、係るヒータ67は、蒸発皿61や蒸発部材64に存するドレン水の蒸発を促進している。
【0043】
更に、蒸発部材64及び蒸発皿61を取付た際に蒸発皿61と対向する位置である風向板53の水平部53Bの下部の左右の端部には、前記ヒータ67の熱を蒸発皿61に伝導しやすくするための突起68が例えば2つずつ縦に形成されている。これにより、風向板53の突起68が蒸発皿61を外側から貯蔵室1の背面に向かって押圧することができる。
【0044】
また、係る突起68は、蒸発皿61と風向板53との隙間をすべて覆うものではないので、ダクト65から侵入する空気を蒸発皿61と風向板53との隙間から排出することができる。
【0045】
以上に説明した風向板53は、貯蔵庫1本体よりも狭い大きさになるように、傾斜部53Aの縁部及び水平部53Bの縁部が所定の幅で外側に折曲されていると共に、貯蔵庫1本体の背面にビス69・・で取り付けられている。
【0046】
一方、貯蔵庫1の機械室8の上方に位置する天面には、機械室8の上方をすべて覆う天板70が取り付けられている。
【0047】
以上の構成において、前記凝縮器用送風機18は常時運転され、凝縮器用送風機18によるパネル20の下部から流通した外気の流れを説明する。パネル20の下部から流通した外気は、図6矢印の如く凝縮器用送風機18によってパネル20と天板70により覆われた機械室8内に吸引される。そして、凝縮器17及び圧縮機16を順次空冷した後、後方に吹き出され、風向板53により形成されたダクト65に入る。ダクト65に流通した暖気は、蒸発皿61及び蒸発部材64を通過し、蒸発皿61及び蒸発部材64に浸透したドレン水を蒸発させながら風向板53に形成された長孔66、開口部53C及び開口部53Dから排出される。
【0048】
係る構成により、前記凝縮器用送風機18から吐出された温かい空気はダクト65内に入り、蒸発皿61周囲を通過して外部に排出されるようになる。
【0049】
そして、蒸発皿61内には親水性の蒸発部材64を設けているので、蒸発皿61内のドレン水を迅速に蒸発処理することができるようになる。
【0050】
特に、蒸発皿61に対応する位置の風向板53両側部には、蒸発部材64が通過可能な開口部53Cを形成したので、この開口部53Cから蒸発部材64の交換・点検などのメンテナンスを行うことができるようになる。また、開口部53Cは両側に形成されているので、冷却貯蔵庫1が設置された場所の左右何れかに回り込めればメンテナンスを行うことができるようになり、保守作業性が著しく改善されるものである。
【0051】
また、風向板53の幅を断熱箱体3よりも狭くしたので、断熱箱体3左右或いは風向板53背面に壁などが密接する設置状態でも、風向板53の外側には通風用の空間が確保される。これにより、劣悪な設置条件においても蒸発皿61内のドレン水の処理能力を確保することが可能となるものである。
【0052】
更に、蒸発皿61を断熱箱体3の背面に接触させ、断熱箱体3の当該接触面にはヒータ67を設けたので、ヒータ67によって蒸発皿61内を加熱し、ドレン水の蒸発を促進させることができるようになるものである。
【0053】
一方、風向板53には蒸発皿61を断熱箱体3の背面に押圧する突起68を形成したので、蒸発皿61とヒータ67との熱交換を効率良く行わせ、ドレン水の蒸発能力を一層向上させることができるようになるものである。
【0054】
そして、蒸発皿61を断熱箱体3に係脱自在に取り付けると共に、断熱箱体3に取り付けられた状態で蒸発皿61は風向板53下端より下方に突出するよう構成したので、蒸発皿61を風向板53下方からダクト65内に挿入して容易に取り付け、取り外しを行うことができるようになる。これにより、蒸発皿61のメンテナンス作業性を向上させることができるようになるものである。
【0055】
また、凝縮器用送風機18を連続運転としたので、ダクト65には常時温かい空気が流通されるようになり、蒸発皿61におけるドレン水処理能力を一層向上させることができるようになるものである。
【0056】
更に、機械室8の上面を天板70により閉塞したので、凝縮器用送風機18から吐出された空気の全てをダクト65内に導くことができるようになり、蒸発皿61におけるドレン水処理能力を尚一層向上させることができるようになるものである。
【0057】
【発明の効果】
以上詳述した如く本発明によれば、本体天面に機械室を構成し、冷却装置の凝縮ユニットを機械室に設置すると共に、本体背面には冷却装置の冷却ユニットからのドレン水を受ける蒸発皿を設け、凝縮ユニットを構成する凝縮器用送風機により後方に空気を吐出して成る冷却貯蔵庫において、上端において機械室に連通し、下端において外部に開放するダクトを本体背面に構成する風向板を設けると共に、蒸発皿をダクト内に配設したので、凝縮器用送風機から吐出された温かい空気はダクト内に入り、蒸発皿周囲を通過して外部に排出されるようになる。
【0058】
そして、蒸発皿内には親水性の蒸発部材を設けているので、蒸発皿内のドレン水を迅速に蒸発処理することができるようになる。
【0059】
特に、蒸発皿に対応する位置の風向板両側部には、蒸発部材が通過可能な開口を形成したので、この開口から蒸発部材の交換・点検などのメンテナンスを行うことができるようになる。また、開口は両側に形成されているので、冷却貯蔵庫が設置された場所の左右何れかに回り込めればメンテナンスを行うことができるようになり、保守作業性が著しく改善されるものである。
【0062】
更に、風向板には蒸発皿をヒータの位置する本体背面に押圧する突起を形成したので、蒸発皿とヒータとの熱交換を効率良く行わせ、ドレン水の蒸発能力を一層向上させることができるようになるものである。
【0063】
請求項2の発明によれば、上記発明に加えて蒸発皿を本体に係脱自在に取り付けると共に、本体に取り付けられた状態で蒸発皿は風向板下端より下方に突出するよう構成したので、蒸発皿を風向板下方からダクト内に挿入して容易に取り付け、取り外しを行うことができるようになる。これにより、蒸発皿のメンテナンス作業性を向上させることができるようになるものである。

[0002]
[Prior art]
Conventionally, this type of drainage water evaporation apparatus for a cooling storage has an evaporating dish installed in a lower machine room as disclosed in, for example, Japanese Patent Laid-Open No. 5-141848, and uses the heat of the high-temperature refrigerant pipe to drain water in the evaporating dish. The method of evaporating is taken. Since it is the structure which concerns, the delivery of the evaporating dish itself can be performed easily and it is highly convenient.
[0003]
In addition to this, as another type of cooling storage, there is a cooling storage having a machine room on the top surface of the main body. In that case, the evaporating dish may be installed on the back of the main body.
[0004]

However, in a cooling storehouse in which the machine room is installed on the top surface of the main body, when the evaporating dish is provided on the back surface of the main body, the cooling storage room is installed on the wall surface of a kitchen or the like for cleaning or replacement. There was a problem that it was difficult to perform maintenance.
[0005]
In addition, when the cooling storage body is pressed against the wall surface of the installation location, the ventilation performance deteriorates, resulting in a problem that drain water treatment (evaporation) performance decreases.
[0006]
The present invention has been made to solve the conventional technical problems, and can perform maintenance such as cleaning or replacement of the evaporating dish in a state where it is installed in a kitchen or the like without any trouble. It is an object of the present invention to provide a cooling storehouse capable of avoiding a decrease in drain water treatment (evaporation) performance accompanying a decrease in performance.
[0007]
[Means for Solving the Problems]
The cooling storage of the present invention comprises a machine room on the top surface of the main body, the condenser unit of the cooling device is installed in the machine room, and an evaporating dish that receives drain water from the cooling unit of the cooling device on the rear surface of the main body. Air is discharged rearward by a condenser blower constituting the condensing unit, and a wind direction is formed in the rear surface of the main body, which communicates with the machine room at the upper end and opens to the outside at the lower end. A plate and a hydrophilic evaporating member provided in the evaporating dish, the evaporating dish is disposed in the duct, and both sides of the wind direction plate at positions corresponding to the evaporating dish are An opening through which the evaporating member can pass is formed, and a projection for pressing the evaporating dish against the back of the main body where the heater is positioned is formed on the wind direction plate.

[0037]
An evaporating member 64 is placed in the evaporating dish 61. The evaporating member 64 is a belt-like body made of a hydrophilic plate such as Universex (trade name) SB. A non-woven fabric such as polyester fiber is used as a base material. Soaked in an alcohol-based solvent to give capillarity and dried and then dried. Because of its fibrous nature, it can be folded in a stretchable manner and has a repulsive force against bending. Is. As a result, the drain water in the evaporating dish 61 is immersed in the evaporating member 64.
[0038]
Next, with reference to FIG. 4, the wind direction plate 53 as an evaporating dish cover attached to the outermost side of the back of the main body of the storage 1 will be described. The wind direction plate 53 is attached from the upper end of the back of the storage 1 and communicates with the machine room 8 to form a duct 65 that opens to the outside at the lower end. The wind direction plate 53 includes an inclined portion 53A formed on the upper side of the wind direction plate 53, a horizontal portion 53B formed parallel to the rear surface at a predetermined interval from the rear surface of the storage 1, and openings 53C formed on both side surfaces.

In particular, since openings 53C through which the evaporating member 64 can pass are formed on both sides of the wind direction plate 53 at a position corresponding to the evaporating dish 61, maintenance such as replacement and inspection of the evaporating member 64 is performed from the opening 53C. Will be able to. Further, since the openings 53C are formed on both sides, the maintenance can be performed if it can go to either the left or right of the place where the cooling storage 1 is installed, and the maintenance workability is remarkably improved. It is.
[0051]
Further, since the width of the wind direction plate 53 is made narrower than that of the heat insulation box 3, there is a ventilation space on the outside of the wind direction plate 53 even in the installation state in which a wall or the like is in close contact with the left and right sides of the heat insulation box 3 or the back of the wind direction plate 53. Secured. Thereby, it becomes possible to ensure the treatment capacity of the drain water in the evaporating dish 61 even under poor installation conditions.
[0052]
Further, since the evaporating dish 61 is brought into contact with the back surface of the heat insulating box 3 and the heater 67 is provided on the contact surface of the heat insulating box 3, the inside of the evaporating dish 61 is heated by the heater 67 to promote the evaporation of drain water. It will be able to let you.
[0053]
On the other hand, since the projection 68 that presses the evaporating dish 61 against the back surface of the heat insulating box 3 is formed on the wind direction plate 53, heat exchange between the evaporating dish 61 and the heater 67 is performed efficiently, and the drain water evaporating ability is further increased. It will be possible to improve.
[0054]
The evaporating dish 61 is detachably attached to the heat insulating box 3 and the evaporating dish 61 is configured to protrude downward from the lower end of the wind direction plate 53 while being attached to the heat insulating box 3. It can be easily inserted and removed by being inserted into the duct 65 from below the wind direction plate 53. Thereby, the maintenance workability of the evaporating dish 61 can be improved.
[0055]
Further, since the condenser blower 18 is continuously operated, warm air is always circulated through the duct 65, and the drain water treatment capacity in the evaporating dish 61 can be further improved.
[0056]
Furthermore, since the upper surface of the machine room 8 is closed by the top plate 70, all of the air discharged from the condenser fan 18 can be guided into the duct 65, and the drain water treatment capacity in the evaporating dish 61 is further reduced. This can be further improved.
