Description

【0001】
【発明の属する技術分野】
本発明は、冷蔵庫や低温ショーケースなどに使用されるドレン水蒸発装置に関するものである。
【0002】
【従来の技術】
従来よりこの種のドレン水蒸発装置は、冷蔵庫などの本体下部の機械室内に金属製の蒸発皿を設け、冷却器からの除霜水をこの蒸発皿にて受けると共に、この蒸発皿内に配設される電気ヒーターにて、蒸発皿内の除霜水を強制的に加熱蒸発処理していた。
【0003】
しかしながら、電気ヒーターによる除霜水の強制蒸発による処理方法では、消費電力が大きく、ランニングコストが高騰する問題があった。特に、大型のショーケースでは水位センサーを設けて水位を検知し、これにより電気ヒーターのON/OFF制御を行っているが、この際、電気ヒーターの通電は100%であるため、消費電力が大きくなる問題があった。また、この電気ヒーターは消費電力が大きいことに加えて通電時間が長いため、省エネルギーの面で改善が望まれていた。
【0004】
そこで、従来では、当該技術的課題を解決するため、ドレン水を溜めるドレン受皿と、このドレン受皿内に設置される複数の蒸発板によりドレン水蒸発装置を構成した(特許文献1参照。)。

【発明が解決しようとする課題】
しかしながら、上記従来のドレン水蒸発装置では、蒸発板を構成する蒸発部材を毛細管作用及び剛性を有する素材にて構成し、当該蒸発板の上面及び両側面に切欠を形成し、係る蒸発板に側方から固定板を挿入し、上部に上部蒸発板を嵌合して構成するものであった。そのため、当該ドレン水蒸発装置の上方から滴下したドレン水は、上部蒸発板に吸収された後、蒸発し、当該蒸発板にて蒸発しきれないドレン水は、毛細管作用により下方へ向かい、上部蒸発板の下方に立設して構成された複数の蒸発板にまで降下し、ドレン水受皿に到達していた。
【0007】
ここで、上部蒸発板から溢出したドレン水は、そのまま垂直方向に滴下していくため、蒸発板の吸収能力以上にドレン水を保持することができず、ドレン水受皿に到達するドレン水が多くなり、蒸発効率が悪いという問題があった。また、上部蒸発板から溢出したドレン水には、ゴミなどが混入していることがあり、当該ゴミまでもがドレン水受皿に到達し、掃除メンテナンスが煩雑となる問題があった。
【0008】
そこで、本発明は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、効率的にドレン水を蒸発させることができるドレン水蒸発装置を提供することを目的とする。
【0009】

【0017】
請求項5の発明のドレン水蒸発装置は、上記各発明において、ドレン水の排出口と最上段のドレン水受け部材の間に、加熱手段にて加熱される一時保留皿を介設したことを特徴とする。
【0018】
請求項5の発明によれば、上記各発明において、ドレン水の排出口と最上段のドレン水受け部材の間に、加熱手段にて加熱される一時保留皿を介設したので、より一層、ドレン水の蒸発効率の向上を図ることができるようになる。
【0019】
【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は本発明を適用した冷却装置のコンデンシングユニットRの斜視図、図2は本発明のドレン水蒸発装置1の斜視図、図3は同じくドレン水蒸発装置1の断面図を示している。
【0020】
本発明のドレン水蒸発装置1を備えるコンデンシングユニットRは、例えば、冷却貯蔵庫を構成する断熱箱体下方に形成される機械室内に配設されるものである。このコンデンシングユニットRは、断熱箱体内に配設される図示しない冷却器と共に冷却装置を構成する圧縮機2と、凝縮器3と、図示しない凝縮器用送風機と、コントロールボックス4と、本発明のドレン水蒸発装置1と、該ドレン水蒸発装置用送風機5などから構成されている。
【0021】
尚、断熱箱体内の冷却器はコンデンシングユニットRの圧縮機2や凝縮器3などと冷媒配管にて接続され、周知の冷媒回路を構成している。また、この冷却器の近傍には、当該冷却器の冷却作用にて冷却される空気を断熱箱体内に循環させるための冷却器用送風機が設けられている。そして、この冷却器が配設される断熱箱体内の冷却室の底壁には、前記機械室内に突出する図示しない排水管が設けられ、冷却器の除霜動作によって冷却器から滴下したドレン水をドレン水蒸発装置1に導くように構成している。
【0022】
また、コンデンシングユニットRを構成するこれらは、同一の取付台6上に設けられている。これにより、コンデンシングユニットRは、図示しないキャスターを利用して取付台6ごと機械室内に納出自在とされ、取付台6上の圧縮機2等のメンテナンス作業が容易に行える構成とされている。
【0023】
次に、図2乃至図3を参照して本発明のドレン水蒸発装置1について説明する。本発明のドレン水蒸発装置1は、一時保留皿13と、複数のドレン水受け部材10と、該ドレン水受け部材10を保持する複数の桁材12と、当該ドレン水受け部材10及び桁材12を収容する蒸発皿11によって構成されている。一時保留皿13、ドレン水受け部材10及び桁材12は、それぞれ毛細管作用及び剛性を有した蒸発板から構成されているものとする。
【0024】
本実施例において、桁材12は、側面に前方から後方に渡ってドレン水受け部材10を挿入するための開口が上方から下方に渡って複数、本実施例では、ドレン水受け部材10を4段設けるため、4段形成されている。また、ドレン水受け部材10は、側端が折曲自在に形成されている。一時保留皿13は、上方に開口した皿状を呈しており、図示しない蒸発パイプやヒータなどの加熱手段が設けられている。
【0025】
これにより、複数の桁材12が立設された状態で、側方の前記開口から側端を真っ直ぐに折曲した各ドレン水受け部材10を挿入することにより、安定してドレン水受け部材10を上下方向に複数段設けることができるようになる。尚、挿入後は、各ドレン水受け部材10の側端を上方に折曲するものとする。そして、最上段のドレン水受け部材10の上方には、各桁材12の上端に位置して前記一時保留皿13が固定される。
【0026】
そして、桁材12により複数段形成された一時保留皿13及びドレン水受け部材10は、前記蒸発皿11上に着脱自在に取り付け、若しくは、載置される。これにより、ドレン水蒸発装置1が構成される。
【0027】
以上の構成により、前記圧縮機22、前記冷却器用送風機、前記凝縮器用送風機及びドレン水蒸発装置用送風機5が運転されると、前記冷却器が冷却作用を発揮し、この冷却器と熱交換した冷気は図示しない吐出口から断熱箱体内に吹き出される。そして、断熱箱体内を循環した後、図示しない吸込口から吸引される。これによって、断熱箱体内は所定の冷蔵温度に維持される。
【0028】
上記冷却運転によって冷却器には着霜が成長するため、冷却装置を制御する制御装置は定期的に圧縮機2を強制停止し、前記冷却器用送風機のみ運転させて冷却器の除霜を行う。この除霜によって冷却室の底壁に流下したドレン水などの排水は、前記排水管を介して、ドレン水蒸発装置1の一時貯留皿13内に受容される。
【0029】
一時貯留皿13内に流入したドレン水は、該貯留皿13を構成する蒸発板に吸収され、大気に露出している部分から蒸発する。また、該貯留皿13には、加熱手段が設けられていることから、当該加熱手段の加熱作用により該貯留皿13を加熱することにより、該貯留皿13に吸収されたドレン水を効果的に蒸発させることができる。そして、当該貯留皿13において蒸発しきれないドレン水は、毛細管作用により各桁材12を介して下方へ向かい、該桁材12に染み込んでいき、桁材12の大気に露出している部分から蒸発する。また、貯留皿13及び当該桁材12にて蒸発しきれないドレン水は、最上段のドレン水受け部材10内に流入し、該ドレン水受け部材10に吸収され、ここにおいても大気に露出している部分から蒸発する。
【0030】
更に、最上段のドレン水受け部材10にても蒸発しきれないドレン水は、上から順に各階層のドレン水受け部材10に流れ落ち、各ドレン水受け部材10にてドレン水を一時的に保水することができる。そして、各ドレン水受け部材10にても蒸発しきれないドレン水のみが、蒸発皿11に到達し、当該蒸発皿11にて蒸発される。
【0031】
係る構成により、ドレン水蒸発装置1の上方に流れ落ちたドレン水は、上述した如く一時貯留皿13及び各階層のドレン水受け部材10にて一時的に保水することができる。そのため、蒸発に有効な面積を大幅に拡張することができ、ドレン水の蒸発効率を向上させることができる。
【0032】
冷却室から流れ落ちたドレン水には、断熱箱体内や冷却室内のゴミ等が混入している場合があるが、当該ドレン水蒸発装置1では、上下方向に一時貯留皿13及び複数段のドレン水受け部材10を備えているため、一時貯留皿13又は何れかのドレン水受け部材10にてゴミ等を捕獲することができ、最終的に蒸発皿11まで該ゴミ等を到達させる不都合を回避することができるようになる。
【0033】
また、本実施例では、各ドレン水受け部材10を保持する上下方向の複数の桁材12は、ドレン水受け部材10と同様に蒸発板から構成されているため、これによってもドレン水を一時的に保水することができ、該ドレン水の蒸発効率を向上させることができる。
【0034】
また、このドレン水蒸発装置1の近傍には、ドレン水蒸発装置用送風機5が設けられているため、この送風機5を運転することにより、より一層、ドレン水の蒸発効率を向上させることができるようになる。
【0035】
桁材12により固定された一時貯留皿13及び複数段のドレン水受け部材10は、蒸発皿11に着脱自在に取り付け、若しくは載置されているため、一時貯留皿13又は各ドレン水受け部材10で捕集されたゴミは、当該貯留皿13又はドレン水受け部材10を外し、別途洗い流すことが可能となる。これにより、清掃作業性が格段に向上する。また、当該一時貯留皿13又はドレン水受け部材10の交換作業性も向上する。
【0036】
尚、他の実施例として、図4に示す如く本発明のドレン水蒸発装置1を構成するドレン水受け部材10を下方に位置するほど、幅・奥行き寸法の大きい蒸発板にて構成してもよいものとする。これにより、下方に位置するドレン水受け部材10の面積が上方のものより拡張されているため、ドレン水蒸発装置1の周囲にドレン水がこぼれ落ちることを抑制することができるようになる。そのため、ドレン水蒸発装置1周囲を汚染する不都合を抑制することができる。
【0037】
尚、上記各実施例において、最上段のドレン水受け部材10とドレン水の排出口、即ち排水管との間に加熱手段を備えた一時保留皿13を設けているが、当該一時保留皿13に加熱手段を設けず、蒸発板を上方に開口した皿状に形成したものを用いてもよいものとする。
【0038】
【発明の効果】
以上詳述した如く本発明によれば、蒸発皿上に、毛細管作用及び剛性を有した蒸発板から成るドレン水受け部材を、上下方向に複数段配置したので、上方から流れ落ちたドレン水を各階層のドレン水受け部材にて一時的に保水することができるようになる。これにより、蒸発に有効な面積を大幅に拡張することができ、ドレン水の蒸発効率を向上させることができるようになる。
【0039】
請求項2の発明によれば、上記発明において、複数のドレン水受け部材を保持する上下方向の桁材を、蒸発板から構成したので、これによってもドレン水を一時的に保水することができ、該ドレン水の蒸発効率を向上させることができるようになる。
【0040】
請求項3の発明によれば、上記各発明において、下方に位置するドレン水受け部材の面積を上方のものより拡張したので、当該ドレン水蒸発装置の周囲にドレン水がこぼれ落ちることを抑制することができるようになる。
【0041】
請求項4の発明によれば、請求項1又は請求項2の発明において、ドレン水受け部材を、蒸発皿に対して着脱自在に設けたので、各ドレン水受け部材で捕集されたゴミは、当該ドレン水受け部材を外し、別途洗い流すことが可能となる。これにより、清掃作業性が格段に向上する。また、当該ドレン水受け部材の交換作業性も向上する。
【0042】
請求項5の発明によれば、上記各発明において、ドレン水の排出口と最上段のドレン水受け部材の間に、加熱手段にて加熱される一時保留皿を介設したので、より一層、ドレン水の蒸発効率の向上を図ることができるようになる。

BEST MODE FOR CARRYING OUT THE INVENTION
Next, an embodiment of the present invention will be described in detail with reference to the drawings. FIG. 1 is a perspective view of a condensing unit R of a cooling device to which the present invention is applied, FIG. 2 is a perspective view of a drain water evaporator 1 of the present invention, and FIG. .
[0020]
The condensing unit R including the drain water evaporator 1 of the present invention is disposed, for example, in a machine room formed below a heat insulating box constituting a cooling storage. The condensing unit R includes a compressor 2, a condenser 3, a not-shown condenser blower, a control box 4, and a control box 4 which constitute a cooling device together with a not-shown cooler disposed in the heat-insulating box. It comprises a drain water evaporator 1 and a blower 5 for the drain water evaporator.
[0021]
In addition, the cooler in the heat insulating box is connected to the compressor 2 and the condenser 3 of the condensing unit R by a refrigerant pipe to constitute a well-known refrigerant circuit. A cooler blower for circulating the air cooled by the cooling action of the cooler in the heat insulating box is provided near the cooler. A drain pipe (not shown) projecting into the machine chamber is provided on a bottom wall of the cooling chamber in the heat insulating box in which the cooler is disposed, and drain water dropped from the cooler by the defrosting operation of the cooler. Is guided to the drain water evaporator 1.
[0022]
These components constituting the condensing unit R are provided on the same mounting base 6. Thereby, the condensing unit R can be delivered to the machine room together with the mounting table 6 using a caster (not shown), and the maintenance work of the compressor 2 and the like on the mounting table 6 can be easily performed. .
[0023]
Next, the drain water evaporator 1 of the present invention will be described with reference to FIGS. The drain water evaporating apparatus 1 of the present invention includes a temporary holding tray 13, a plurality of drain water receiving members 10, a plurality of girder members 12 for holding the drain water receiving members 10, the drain water receiving member 10 and the girder members. The evaporating dish 11 accommodates the evaporating dish 12. It is assumed that the temporary storage tray 13, the drain water receiving member 10, and the beam member 12 are each composed of an evaporating plate having capillary action and rigidity.
[0024]
In the present embodiment, the girder member 12 has a plurality of openings for inserting the drain water receiving member 10 from the upper side to the lower side in the side surface from the front to the rear. In order to provide steps, four steps are formed. Further, the drain water receiving member 10 is formed so that a side end thereof can be freely bent. The temporary storage tray 13 has a dish shape opened upward, and is provided with heating means such as an evaporation pipe and a heater (not shown).
[0025]
In this way, in a state where the plurality of beam members 12 are erected, the drain water receiving members 10 whose side ends are bent straight from the side openings are inserted stably. Can be provided in a plurality of stages in the vertical direction. After insertion, the side end of each drain water receiving member 10 is bent upward. The temporary storage tray 13 is fixed above the uppermost drain water receiving member 10 at the upper end of each girder member 12.

The temporary holding tray 13 and the drain water receiving member 10 formed in a plurality of stages by the girder members 12 are detachably attached or placed on the evaporating tray 11. Thus, the drain water evaporator 1 is configured.
[0027]
With the above configuration, when the compressor 22, the blower for the cooler, the blower for the condenser, and the blower 5 for the drain water evaporator are operated, the cooler exerts a cooling action and exchanges heat with the cooler. Cool air is blown out from a discharge port (not shown) into the heat insulating box. Then, after circulating in the heat insulating box, the air is sucked from a suction port (not shown). Thereby, the inside of the heat insulating box is maintained at a predetermined refrigeration temperature.
[0028]
Since frost grows on the cooler by the cooling operation, the control device that controls the cooling device periodically forcibly stops the compressor 2 and operates only the blower for the cooler to defrost the cooler. Drainage such as drain water that has flowed down to the bottom wall of the cooling chamber due to this defrost is received in the temporary storage tray 13 of the drain water evaporator 1 via the drain pipe.
[0029]
The drain water flowing into the temporary storage tray 13 is absorbed by the evaporating plate constituting the storage tray 13 and evaporates from a portion exposed to the atmosphere. Further, since the storage plate 13 is provided with a heating unit, the storage plate 13 is heated by the heating action of the heating unit, so that the drain water absorbed by the storage plate 13 can be effectively removed. Can be evaporated. Then, the drain water that cannot be completely evaporated in the storage dish 13 goes downward through each girder member 12 by capillary action, soaks into the girder member 12, and from the portion of the girder member 12 exposed to the atmosphere.
