Description

この発明は、例えば、飲料水供給装置（ウォ−ターサ−バー等と一般的に呼称されている）等で実施される冷却タンクの冷却構造及びその製造方法に係わり、更に詳しくは省エネ、高機能、経済的な圧縮機型冷却手段を備えた斬新な冷却タンク及びその製造方法に関するものである。   The present invention relates to a cooling structure for a cooling tank and a method for manufacturing the same, for example, performed in a drinking water supply device (generally called a water server or the like). The present invention relates to a novel cooling tank equipped with an economical compressor type cooling means and a method for manufacturing the same.

従来、飲料水供給装置（ウォ−ターサ−バー等と一般的に呼称されている）等で実施される冷却タンクの冷却構造としては、例えば、上部が開口し、底板に内部と連通する吐出管（吐出口）を設けたステンレス等の金属材料により構成された有底円筒状の冷却タンク本体の外壁冷却領域に、フロンガス等の冷媒を流通させる所定の径の銅管（銅管蒸発器）をスパイラル状に巻付けて構成し、この銅管内に所定容量の冷媒を流通させることで、冷却タンクに収容した飲料水等の流体を所定温度（例えば、４°Ｃ〜８°Ｃの範囲）に冷却し、何時でも冷却タンクに設けた吐出管（吐出口）から冷水を注出させることが出来るように構成されている（例えば、特許文献１、特許文献２参照）。   Conventionally, as a cooling structure of a cooling tank implemented by a drinking water supply device (generally called a water server or the like), for example, a discharge pipe that is open at the top and communicates with the inside of the bottom plate A copper tube (copper tube evaporator) with a predetermined diameter for circulating a refrigerant such as chlorofluorocarbon gas in the outer wall cooling region of the bottomed cylindrical cooling tank body made of a metal material such as stainless steel provided with a (discharge port). It is configured by winding in a spiral shape, and a predetermined volume of refrigerant is circulated in the copper pipe, so that the fluid such as drinking water stored in the cooling tank has a predetermined temperature (for example, a range of 4 ° C to 8 ° C). The chilled water can be poured out from the discharge pipe (discharge port) provided in the cooling tank at any time (see, for example, Patent Document 1 and Patent Document 2).

ところで、このような従来の冷却タンクの冷却構造は、上述したようにステンレス製の冷却タンク本体の外壁冷却領域に、冷媒を流通させる所定の径の銅管（銅管蒸発器）をスパイラル状に巻付けて冷却させる構造であったため、銅管外壁と冷却タンク本体の外壁との間での接触軌跡が一本の螺旋状線接触状態となっており、接触面積（線接触）が狭い上に、冷媒が銅管を介して冷却タンク本体の外壁を間接的に冷却することから冷却タンク本体の冷水収容容量にもよるが一定温度に冷却させる冷却時間が長くかかり、冷却効率が極めて悪いと言う問題があった。   By the way, the cooling structure of such a conventional cooling tank has a spiral shape of a copper pipe (copper pipe evaporator) having a predetermined diameter for circulating a refrigerant in the outer wall cooling region of the stainless steel cooling tank body as described above. Since it was wound and cooled, the contact trajectory between the outer wall of the copper tube and the outer wall of the cooling tank body is in a single spiral line contact state, and the contact area (line contact) is narrow. , Because the coolant indirectly cools the outer wall of the cooling tank body through the copper pipe, it takes a long cooling time to cool to a certain temperature, although it depends on the cooling water capacity of the cooling tank body, and the cooling efficiency is extremely poor There was a problem.

また、冷却手段として用いる熱伝導性の良い銅管の銅金属材料は、現在の金属資源単価も高く、原料コストが嵩む上に、貴金属にとっても不要な無駄を招くことから、近年の省エネ、省資源の方針にそぐわないと言う問題があった。   In addition, the copper metal material of copper pipes with good thermal conductivity used as a cooling means has a high current metal resource unit price, increases raw material costs, and causes unnecessary waste for precious metals. There was a problem that it did not match the resource policy.

そこで、従来から経済的で、高効率、信頼性が高く、冷却タンク本体を直接冷却することができる飲料水等の冷却水の冷却タンクの構造及びその製造方法が要望されていた。   Therefore, there has been a demand for a cooling water cooling tank structure such as drinking water that is economical, highly efficient, highly reliable, and capable of directly cooling the cooling tank body, and a method for manufacturing the same.

以下、添付図面に基づき、この発明の実施形態を説明する。   Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

図１は、この発明を実施した冷却タンクの全体を示す外観斜視図、図２はこの発明を実施した冷却タンクの背面側拡大斜視図、図３は図２の平面斜視図、図４は図２のＡ−Ａ矢視半断面図を示し、この冷却タンクは、図１〜図４に示すように、上部１ａが開口し、底板１ｂに内部と連通する吐出管２を設けたステンレス板等の金属製材料により構成された有底筒状の冷却タンク本体１Ａと、冷却タンク１Ａの外壁冷却領域１ｘに被嵌し、冷却タンク１Ａ内の飲料水等の流体を所定温度に冷却する冷却手段３を設けた冷却構造になっている。   1 is an external perspective view showing the entire cooling tank embodying the present invention, FIG. 2 is an enlarged rear perspective view of the cooling tank embodying the present invention, FIG. 3 is a plan perspective view of FIG. 2, and FIG. 2 shows a half cross-sectional view taken along the line A-A. As shown in FIGS. 1 to 4, this cooling tank is made of a stainless steel plate or the like in which an upper portion 1a is opened and a discharge pipe 2 communicating with the inside is provided in a bottom plate 1b. A cooling tank body 1A having a bottomed cylindrical shape made of a metal material and a cooling means that fits on the outer wall cooling region 1x of the cooling tank 1A and cools a fluid such as drinking water in the cooling tank 1A to a predetermined temperature. 3 has a cooling structure.

前記冷却手段３は、冷却タンク本体１Ａと少なくとも同じステンレス板等の金属材料で構成された筒状ジャケット４を水密的に被嵌するとと共に、筒状ジャケット４の上部または下部の一方の外壁面からの長手方向に沿って溶接等の接合加工手段により接合しながら所定のピッチＰで冷却タンク１Ａの外壁面と筒状ジャケット４との間に所定の断面形状（この実施形態では半円弧状であるが、この形状には限定されない）を有するスパイラル状の冷媒通路５を一体的に形成してある。   The cooling means 3 fits a cylindrical jacket 4 made of at least the same metal material as the cooling tank body 1A, such as a stainless steel plate, in a watertight manner, and from one outer wall surface of the upper or lower portion of the cylindrical jacket 4 A predetermined cross-sectional shape (in this embodiment, a semicircular arc shape) between the outer wall surface of the cooling tank 1A and the cylindrical jacket 4 at a predetermined pitch P while being joined by a joining processing means such as welding along the longitudinal direction. However, it is not limited to this shape, and a spiral refrigerant passage 5 having a single shape is integrally formed.

そして、この冷媒通路５の一方にフロンガス等の冷媒の流入口６を設け、他方に冷媒の流出口７が設けてある。前記冷却タンク１Ａ及び筒状ジャケット４は、０．１〜１ｍｍの熱伝導が良く、防錆効果の高いステンレス板等の金属製薄板で成形してあり、また前記冷却手段３のスパイラル状の冷媒通路５は、冷却タンク１Ａの長手方向に沿って２〜１０ｍｍピッチで形成してある。   One of the refrigerant passages 5 is provided with an inlet 6 for refrigerant such as Freon gas, and the other is provided with an outlet 7 for refrigerant. The cooling tank 1A and the cylindrical jacket 4 are formed of a thin metal plate such as a stainless plate having a good thermal conductivity of 0.1 to 1 mm and having a high rust prevention effect. The passages 5 are formed at a pitch of 2 to 10 mm along the longitudinal direction of the cooling tank 1A.

前記冷却タンク１Ａ及び筒状ジャケット４の金属製薄板は、余り薄いと強度的な問題があり、また厚すぎると、加工や熱効率の点で上記の範囲が好ましく、またスパイラル状の冷媒通路５のピッチも冷却タンク本体１Ａ冷却効率から２〜１０ｍｍピッチで形成するのが好ましい。   The cooling tank 1A and the metal thin plate of the cylindrical jacket 4 have a problem of strength if they are too thin, and if they are too thick, the above range is preferable in terms of processing and thermal efficiency.

A capillary tube 10 having a predetermined length is inserted from the lower end side of the connecting bent pipe 8.

次に、この発明の冷却タンク１Ａの製造方法を図４〜図７を参照しながら具体的に説明する。まず上部１ａが開口し、底板１ｂに内部と連通する吐出管２を設けたステンレス板等の金属製材料により構成された所定径の有底筒状の冷却タンク本体１Ａを予め製造しておき、この有底筒状の冷却タンク本体１Ａ外壁冷却領域１ｘに、冷却タンク本体１Ａの一方から予め冷却タンク本体１Ａと少なくとも同じ金属材料で構成された筒状ジャケット４を被せるように挿入して水密的に被嵌する。   Next, the manufacturing method of the cooling tank 1A according to the present invention will be specifically described with reference to FIGS. First, a bottomed cylindrical cooling tank body 1A having a predetermined diameter and made of a metal material such as a stainless steel plate provided with a discharge pipe 2 communicating with the inside of the bottom plate 1b with an opening at the top 1a is manufactured in advance. The bottomed cylindrical cooling tank main body 1A outer wall cooling region 1x is inserted with a cylindrical jacket 4 made of at least the same metal material as that of the cooling tank main body 1A in advance from one of the cooling tank main bodies 1A to be watertight. To fit.

このように組付けた冷却タンク本体１Ａを図７に示すように、製造工程の成形ドラム１１に挿入して肩持ち状態で支持した状態で、筒状ジャケット４の上部または下部の一方の外壁面からの長手方向に沿って加圧ロール１２を使用したロール加圧加工方法（または締まり嵌め結合または滑り嵌め結合、溶接接合方法から選ばれた一つ）の接合加工手段を使用して、前記冷却タンク本体１Ａを一定方向に所定の速度で回転させながら、かつ接合加工手段の加圧ロール１２を冷却タンク本体１Ａの軸方向に加圧しながら一定のスピードで移動させると共に溶接させると、冷却タンク本体１Ａの外壁面と筒状ジャケット４との間には所定の断面形状（半円弧状）を有するスパイラル状の冷媒通路５が一体的に形成される。   As shown in FIG. 7, the cooling tank body 1A assembled in this way is inserted into the molding drum 11 in the manufacturing process and supported in a shoulder-held state, and one outer wall surface of the upper or lower portion of the cylindrical jacket 4 is supported. The above-mentioned cooling is performed using a joining means of a roll pressing method (or one selected from an interference fit coupling, a sliding fit coupling, and a welding joining method) using a pressure roll 12 along the longitudinal direction from When the tank main body 1A is rotated at a predetermined speed in a predetermined direction and the pressure roll 12 of the joining processing means is moved at a constant speed while being pressed in the axial direction of the cooling tank main body 1A and welded, the cooling tank main body is obtained. Between the outer wall surface of 1A and the cylindrical jacket 4, a spiral refrigerant passage 5 having a predetermined cross-sectional shape (semicircular arc shape) is integrally formed.

この冷媒通路５の一方に上述した連結屈曲パイプ８を連結する冷媒の流入口６を設け、他方にリターンパイプ９を設けた冷媒の流出口７を設け、更に連結屈曲パイプ８の下端側からは、所定の長さのキャピラリチューブ１０が挿入して構成するものである。   One of the refrigerant passages 5 is provided with the refrigerant inlet 6 for connecting the above-described connecting bent pipe 8, the other is provided with the refrigerant outlet 7 provided with the return pipe 9, and further from the lower end side of the connecting bent pipe 8. The capillary tube 10 having a predetermined length is inserted and configured.

このようにして製造した冷却タンク本体１Ａ内に所定量の飲料水を収容しておき、前記冷媒通路５の一方からフロンガス等の圧縮冷媒を所定量順次送りこみ、他方から流出させて冷却タンク本体内の液体を一定温度以下に冷却するものである。   A predetermined amount of drinking water is accommodated in the cooling tank main body 1A thus manufactured, a predetermined amount of compressed refrigerant such as chlorofluorocarbon gas is sequentially sent from one of the refrigerant passages 5, and the cooling tank main body flows out from the other. The liquid inside is cooled below a certain temperature.

このように、冷却手段３は、冷却タンク本体１Ａと少なくとも同じ金属材料で構成された筒状ジャケット４とを水密的に被嵌するとと共に、筒状ジャケット４の上部または下部の一方の外壁面からの長手方向に沿って接合加工手段により接合しながら所定のピッチで冷却タンク本体１Ａの外壁面と筒状ジャケット４との間に所定の断面形状を有するスパイラル状の冷媒通路５を一体的に形成し、この冷媒通路５の一方に冷媒の流入口６を設け、他方に冷媒の流出口７を設けたので、従来の冷却水の冷水タンクに較べて消費電力を約２５％節約することが出来る等極めて経済的であり、また冷却効率が高い上に信頼性も高いものとすることが出来る。   In this way, the cooling means 3 fits the cooling tank body 1A and the cylindrical jacket 4 made of at least the same metal material in a watertight manner, and from one outer wall surface of the upper or lower portion of the cylindrical jacket 4. A spiral refrigerant passage 5 having a predetermined cross-sectional shape is integrally formed between the outer wall surface of the cooling tank main body 1A and the cylindrical jacket 4 at a predetermined pitch while being bonded along the longitudinal direction by a bonding processing means. In addition, since the refrigerant inlet 6 is provided in one of the refrigerant passages 5 and the refrigerant outlet 7 is provided in the other, the power consumption can be reduced by about 25% compared to the conventional cooling water chilled water tank. It is extremely economical, and the cooling efficiency is high and the reliability is high.

また、冷却タンク本体１Ａを直接冷却することができるので極めて効率的であり、部品点数も少なく高価な金属族材料を使用せずに簡易に製造することが出来るので、従来の冷却水の冷水タンクに較べて安価に製作でき、従来の冷却タンクの冷却構造よりもコストダウンを図ることが出来る。   Moreover, since the cooling tank body 1A can be directly cooled, it is extremely efficient and can be easily manufactured without using an expensive metal group material with a small number of parts. Compared with the conventional cooling tank, it can be manufactured at a lower cost and the cost can be reduced as compared with the cooling structure of the conventional cooling tank.
