Description

本発明は、冷却水を貯留し、該冷却水に浸漬している冷却管を通過した飲料を冷却する冷却水槽に関するものである。 The present invention relates to a cooling water tank for storing cooling water and cooling a beverage that has passed through a cooling pipe immersed in the cooling water.

たとえば、飲料を冷却して供給する飲料ディスペンサには、供給する飲料を冷却するための冷却水槽が設けられている。この冷却水槽には、飲料冷却用の冷却水が貯留され、その冷却水中に冷却装置に連通するエバポレータを設け、このエバポレータの周囲に形成させたアイスバンク（氷塊）の蓄熱量を利用して冷却水温度を略０℃に保つようにしている。そして、この冷却水にコイル状の金属製パイプなどからなる冷却管を浸漬し、該冷却管を通過させて冷却した飲料を供給する（例えば、特許文献１参照）。
特開２００２−８００９５号公報 For example, a beverage dispenser for cooling and supplying a beverage is provided with a cooling water tank for cooling the beverage to be supplied. In this cooling water tank, cooling water for beverage cooling is stored, an evaporator communicating with the cooling device is provided in the cooling water, and cooling is performed using the amount of heat stored in an ice bank (ice block) formed around the evaporator. The water temperature is kept at about 0 ° C. And the cooling pipe which consists of a coil-shaped metal pipe etc. is immersed in this cooling water, and the drink which cooled by letting this cooling pipe pass is supplied (for example, refer patent document 1).
Japanese Patent Laid-Open No. 2002-80095

しかしながら、飲料を連続して供給すると、冷却管を通過する飲料の熱量で冷却水温度が上昇してアイスバンクが溶けだし、さらに冷却水温度が上昇して冷却管を通過する飲料が冷えなくなると、程良く冷やした飲料を提供することができなくなる虞が生じる。
このようなときには、飲料ディスペンサの天板を取り外して冷却水槽内に氷を投入して冷却水温度を下げ、程良く冷やした飲料の販売を続けるようにしている。
ところが、冷却水槽の断熱壁フランジ部は水平になっているため、氷を投入する際や冷却水を補充する際に飛び散った氷や水がフランジ部に付着し、それが水槽と外装部品との間などを伝い床に垂れる不具合が生じる。
本発明は、上記実情に鑑みて、冷却水を貯留し、該冷却水に浸漬している冷却管を通過した飲料を冷却する冷却水槽に関し、冷却水槽に氷を投入したり、冷却水を補充する際に氷や水が飛び散っても、床に垂れることのない冷却水槽を提供することを目的とする。 However, when the beverage is continuously supplied, the cooling water temperature rises due to the amount of heat of the beverage passing through the cooling pipe and the ice bank starts to melt, and further the cooling water temperature rises and the beverage passing through the cooling pipe does not cool down. There is a risk that it will not be possible to provide a moderately chilled beverage.
In such a case, the top plate of the beverage dispenser is removed, ice is poured into the cooling water tank to lower the cooling water temperature, and the sale of the beverage cooled moderately is continued.
However, since the heat insulation wall flange of the cooling water tank is horizontal, the ice and water scattered when the ice is poured in or when the cooling water is replenished adheres to the flange part, and this is the difference between the water tank and the exterior parts. There is a problem of hanging on the floor through the space.
In view of the above circumstances, the present invention relates to a cooling water tank for storing cooling water and cooling a beverage that has passed through a cooling pipe immersed in the cooling water. The purpose of the present invention is to provide a cooling water tank that does not drip on the floor even when ice or water splashes.

上記目的を達成するため、本発明の請求項１に係る冷却水槽は、冷却水を貯留し、該冷却水に浸漬している冷却管を通過した飲料を冷却する冷却水槽において、
前記冷却水槽の壁面を形成する断熱壁上端面の少なくとも一部を傾斜面としたことを特徴とする。 In order to achieve the above object, the cooling water tank according to claim 1 of the present invention is a cooling water tank for storing cooling water and cooling a beverage that has passed through a cooling pipe immersed in the cooling water.
At least part of the upper end surface of the heat insulating wall forming the wall surface of the cooling water tank is an inclined surface.

請求項１の発明によれば、冷却水槽の壁面を形成する断熱壁上端面の少なくとも一部を傾斜面としたので、投入された氷が断熱壁上端面に載って溶解することなく確実に冷却水槽内に落下するようになる。そして、氷が冷却水に落下して生じた飛沫も冷却水槽の内側方向に傾斜した上端面により冷却水槽内に流れ落ちるようになる。このように、冷却水を貯留し、該冷却水に浸漬している冷却管を通過した飲料を冷却する冷却水槽に関し、冷却水槽に氷を投入したり、冷却水を補充する際に氷や水が飛び散っても、床に垂れることのない冷却水槽を提供することができる。 According to the first aspect of the present invention, since at least a part of the upper end surface of the heat insulating wall forming the wall surface of the cooling water tank is an inclined surface, the charged ice is reliably cooled without melting on the upper end surface of the heat insulating wall. It will fall into the aquarium. And the splash generated by the ice falling on the cooling water also flows down into the cooling water tank by the upper end surface inclined in the inner direction of the cooling water tank. In this way, with respect to a cooling water tank that stores cooling water and cools a beverage that has passed through a cooling pipe immersed in the cooling water, ice or water is added to the cooling water tank when ice is added to or refilled with cooling water. It is possible to provide a cooling water tank that does not sag on the floor even if splashes.

以下に添付図面を参照して、本発明に係る冷却水槽の好適な実施の形態について詳細に説明する。
図１は、本発明をビールディスペンサに適用した場合の概略構成を示し、（ａ）は正面図、（ｂ）は側面図、（ｃ）は天面図である。図１に示すように、ビールを冷却して供給するビールディスペンサ１の天板２と側板３で構成する外装板内には、冷却水４を貯留する冷却水槽５と、この冷却水４中に浸漬したエバポレータ（蒸発器ともいう）６、コンプレッサ７、コンデンサー（凝縮器ともいう）８、コンデンサー８を冷却する送風ファン９などで構成する冷却装置１０が設けられている。ビールディスペンサ１の前面には、冷却水４中に浸漬した冷却パイプ（冷却管ともいう）１１の注出側端部に連通する注出バルブ１２が取り付けてあり、冷却パイプ１１は図示しないガスボンベから圧送される炭酸ガスの圧力で貯蔵タンクから押し出されたビールを供給するための供給パイプ１３に連通している。注出バルブ１２は操作レバー１２ａを揺動操作すると、これに従動する弁機構を開放して、冷却パイプ１１を通過して冷やされたビールが注出ノズル１２ｂから注出される。また、注出バルブ１２の下方には、簀の子１４ａを設けたドレン皿１４が取り付けられ、注出ノズル１２ｂから滴下する飲料を受容するとともに、ビールジョッキなどの容器を載置することができる。 Exemplary embodiments of a cooling water tank according to the present invention will be described below in detail with reference to the accompanying drawings.
FIG. 1 shows a schematic configuration when the present invention is applied to a beer dispenser, where (a) is a front view, (b) is a side view, and (c) is a top view. As shown in FIG. 1, a cooling water tank 5 for storing cooling water 4 and a cooling water tank 4 for storing cooling water 4 are provided in an exterior plate constituted by a top plate 2 and a side plate 3 of a beer dispenser 1 that cools and supplies beer. A cooling device 10 is provided that includes an immersed evaporator (also referred to as an evaporator) 6, a compressor 7, a condenser (also referred to as a condenser) 8, a blower fan 9 that cools the condenser 8, and the like. On the front surface of the beer dispenser 1, a pouring valve 12 communicating with the pouring side end of a cooling pipe (also called a cooling pipe) 11 immersed in the cooling water 4 is attached. The cooling pipe 11 is connected to a gas cylinder (not shown). It communicates with the supply pipe 13 for supplying the beer pushed out of the storage tank with the pressure of the carbon dioxide gas being pumped. When the dispensing valve 12 is operated to swing the operating lever 12a, the valve mechanism that follows the opening is opened, and the beer cooled through the cooling pipe 11 is poured out from the dispensing nozzle 12b. In addition, a drain pan 14 provided with a scissors 14a is attached below the pouring valve 12, so that a beverage dripping from the pouring nozzle 12b can be received and a container such as a beer mug can be placed thereon.

図２は図１のＡ−Ａ部を矢印方向に見た断面側面図、図３は図１のＢ−Ｂ部を矢印方向に見た断面側面図である。図に示すように、冷却水４を貯留する冷却水槽５は、側面および底面を断熱壁２１で構成し、その上方を開口した略直方体の水槽であり、断熱壁２１の上端面２１ａを冷却水槽５の内側方向に傾斜した面としている。また、コンプレッサ７、コンデンサー８、送風ファン９と共に冷却装置１０を構成するエバポレータ６は、コイル状に巻回されて冷却水槽５の断熱壁２１内側に配設され、冷媒の蒸発熱でその周囲にアイスバンク２２を形成し、この蓄熱量を利用して冷却水４の温度を略０℃に保つようにしている。さらに、コイル状に巻回されたエバポレータ６の内側には、ステンレス製の冷却パイプ１１がコイル状に巻回されて冷却水４に浸漬するように配置され、この冷却パイプ１１の供給側端部は断熱壁２１の上部から延出されて供給パイプ１３に連通する。断熱壁２１上方には冷却水４を撹拌するための撹拌モータ２３の取り付け部材２６が横に架け渡されて取り付けられ、モータ軸２４には撹拌羽根２５を装着している。この撹拌羽根２５は、撹拌モータ２３の回転に伴って回転し、冷却水槽５内の冷却水４を下方に向けて流動させ、冷却パイプ１１を通過する飲料を効率よく冷やすようにしている。 2 is a cross-sectional side view of the AA portion of FIG. 1 as viewed in the arrow direction, and FIG. 3 is a cross-sectional side view of the BB portion of FIG. 1 as viewed in the arrow direction. As shown in the figure, the cooling water tank 5 for storing the cooling water 4 is a substantially rectangular parallelepiped water tank whose side surface and bottom surface are constituted by a heat insulating wall 21 and opened above, and the upper end surface 21a of the heat insulating wall 21 is a cooling water tank. 5 is a surface inclined in the inner direction. The evaporator 6 that constitutes the cooling device 10 together with the compressor 7, the condenser 8, and the blower fan 9 is wound in a coil shape and disposed inside the heat insulating wall 21 of the cooling water tank 5, and is surrounded by the heat of evaporation of the refrigerant. An ice bank 22 is formed, and the temperature of the cooling water 4 is maintained at about 0 ° C. by using this heat storage amount. Further, inside the evaporator 6 wound in a coil shape, a stainless steel cooling pipe 11 is disposed so as to be wound in a coil shape and immersed in the cooling water 4, and the supply side end portion of the cooling pipe 11 is arranged. Is extended from the upper part of the heat insulating wall 21 and communicates with the supply pipe 13. A mounting member 26 of a stirring motor 23 for stirring the cooling water 4 is horizontally installed above the heat insulating wall 21, and a stirring blade 25 is mounted on the motor shaft 24. The stirring blade 25 rotates with the rotation of the stirring motor 23, and causes the cooling water 4 in the cooling water tank 5 to flow downward, so that the beverage passing through the cooling pipe 11 is efficiently cooled.

このように、冷却水槽５の断熱壁２１の上端面２１ａを冷却水槽５の内側方向に傾斜した面としているので、投入された氷が断熱壁２１上端面２１ａに載っても溶解することなく確実に冷却水槽５内に落下する。そして、氷が冷却水４に落下して生じた飛沫も冷却水槽５の内側方向に傾斜した上端面２１ａにより冷却水槽５内に流れ落ちる。 Thus, since the upper end surface 21a of the heat insulating wall 21 of the cooling water tank 5 is inclined to the inner side of the cooling water tank 5, even if the thrown-in ice is placed on the upper end surface 21a of the heat insulating wall 21, it does not melt. Falls into the cooling water tank 5. Then, the splash generated by the ice falling on the cooling water 4 also flows down into the cooling water tank 5 by the upper end surface 21 a inclined in the inner direction of the cooling water tank 5.
