特開２００２−２６１２００号公報JP 2002-261200 A

特許文献１に記載の飲料ディスペンサにおいては、装置を小型化するにあたって冷却水槽の容量を小さくすると、電装部品収容箱の底壁下面が冷却水槽の水面に近くなり、電装部品収容箱内は冷却水の冷熱により冷やされて結露しやすかった。また、冷却水槽の上側に、電装部品収容箱と支持板とを取り付けているが、これらの組み立て工数が多くて作業性が良くないという問題があった。本発明は、このような問題を解決することを目的とする。   In the beverage dispenser described in Patent Document 1, when the capacity of the cooling water tank is reduced in downsizing the apparatus, the bottom surface of the bottom wall of the electrical component storage box becomes close to the water surface of the cooling water tank, and the interior of the electrical component storage box is cooled with water. It was easy to condense by being cooled by the cold heat. Moreover, although the electrical component storage box and the support plate are attached to the upper side of the cooling water tank, there is a problem in that the number of assembly steps is large and workability is not good. The present invention aims to solve such problems.

本発明は上記課題を解決するため、冷却水を貯える冷却水槽と、冷却水槽内で撹拌モータにより回転して冷却水を撹拌するための撹拌羽根と、冷却水槽内に設けられた冷凍装置の蒸発管と、冷却水槽内に設けられた飲料を冷却するための飲料冷却管と、冷却水槽の周縁部上端に支持されて電装部品を収容する収容部を有する電装部品収容箱とを備えた飲料冷却装置であって、電装部品収容箱には冷却水槽内に延出して撹拌モータを支持する支持板部を一体的に設け、支持板部の上面には撹拌モータを乗載するとともに収容部の外周壁と一体的となる突条を設けたことを特徴とする飲料冷却装置を提供するものである。   In order to solve the above-described problems, the present invention provides a cooling water tank for storing cooling water, a stirring blade for rotating the stirring water by a stirring motor in the cooling water tank and stirring the cooling water, and evaporation of a refrigeration apparatus provided in the cooling water tank. Beverage cooling provided with a pipe, a beverage cooling pipe for cooling the beverage provided in the cooling water tank, and an electrical component storage box having a storage part that is supported by the upper edge of the cooling water tank and stores electrical components The electrical component storage box is integrally provided with a support plate portion that extends into the cooling water tank and supports the stirring motor, and the stirring plate is mounted on the upper surface of the support plate portion and the outer periphery of the storage portion It is an object of the present invention to provide a beverage cooling device characterized by providing a protrusion that is integral with a wall.

上記のように構成した飲料冷却装置においては、電装部品収容箱には冷却水槽内に延出して撹拌モータを支持する支持板部を一体的に設け、支持板部の上面には撹拌モータを乗載するとともに収容部の外周壁と一体的となる突条を設けたので、部品点数及び組立て工数を減らすことができ、撹拌モータから発生する熱を支持板部に拡散させることなく突条により収容部内に伝達して、電装部品収容箱内が冷却水の冷熱により冷やされて結露するのを防ぐことができる。   In the beverage cooling apparatus configured as described above, the electrical component storage box is integrally provided with a support plate portion that extends into the cooling water tank and supports the stirring motor, and the stirring motor is mounted on the upper surface of the support plate portion. Since the ridges are mounted and integrated with the outer peripheral wall of the housing part, the number of parts and assembly man-hours can be reduced, and the heat generated from the stirring motor is accommodated by the ridges without diffusing to the support plate part. It can be transmitted to the inside of the electrical component storage box, and the inside of the electrical component housing box can be prevented from being cooled by the cold heat of the cooling water and causing condensation.

上記のように構成した飲料冷却装置においては、突条は撹拌モータの収容部側となる一部を乗載するようにするのが好ましく、このようにしたときには、撹拌モータから発生する熱が収容部と反対側に伝達されるのを防ぐことができ、撹拌モータから発生する熱の伝達効率を上げることができる。   In the beverage cooling apparatus configured as described above, it is preferable that the ridge is mounted on a part of the stirring motor on the housing portion side, and in this case, the heat generated from the stirring motor is stored. It is possible to prevent the heat from being transmitted to the side opposite to the part, and to increase the efficiency of transferring heat generated from the stirring motor.

上記のように構成した飲料冷却装置においては、電装部品収容箱の収容部の底壁下面には隙間を設けて冷却水遮蔽板を取り付けるようにするのが好ましく、このようにしたときには、冷却水槽内の冷却水が冷却水遮蔽板によって電装部品収容箱の収容部の底壁下面に付着するのを防ぐことができ、また、電装部品収容箱の収容部の底壁下面と冷却水遮蔽板との間の空気により冷却水槽内の冷却水の冷熱が伝わりにくくなり、電装部品収容箱内が冷やされて結露するのをさらに防ぐことができる。   In the beverage cooling apparatus configured as described above, it is preferable to provide a cooling water shielding plate with a gap provided on the lower surface of the bottom wall of the storage part of the electrical component storage box. The cooling water inside can be prevented from adhering to the bottom wall lower surface of the housing part of the electrical component storage box by the cooling water shielding plate, and the bottom wall lower surface of the housing part of the electrical component storage box and the cooling water shielding plate The cold air of the cooling water in the cooling water tank is not easily transmitted by the air between, and it is possible to further prevent the inside of the electrical component storage box from being cooled and condensed.

上記のように構成した飲料冷却装置においては、電装部品収容箱には撹拌モータの周囲の空気を電装部品収容箱の収容部の底壁下面側に送るための送風通路を設けるようにするのが好ましく、このようにしたときには、撹拌モータの周囲の熱を持った空気が電装部品収容箱の収容部の底壁下面側に送られて、電装部品収容箱の収容部内が低温となって結露するのをさらに防ぐことができる。この飲料冷却装置においては、支持板部は電装部品収容箱の収容部の外周壁より下方に延びる接続壁部から冷却水槽内に延出するようにして電装部品収容箱の収容部の底壁より下側に設けられるようにし、接続壁部に送風通路を設けるようにすれば、撹拌モータの周囲の熱を持った空気が送風通路を通過して電装部品収容箱の収容部の底壁下面に送出されるようになり、収容部内が冷やされて結露するのをさらに防ぐことができる。   In the beverage cooling apparatus configured as described above, the electrical component housing box is provided with a ventilation passage for sending the air around the agitation motor to the bottom wall lower surface side of the housing portion of the electrical component housing box. Preferably, when this is done, air having heat around the agitation motor is sent to the lower surface of the bottom surface of the housing part of the electrical component storage box, and the interior of the storage part of the electrical component storage box becomes low in temperature and dew condensation occurs. Can be further prevented. In this beverage cooling apparatus, the support plate portion extends from the connecting wall portion extending downward from the outer peripheral wall of the electrical component housing box housing portion into the cooling water tank, and from the bottom wall of the electrical component housing box housing portion. If it is provided on the lower side and a ventilation passage is provided in the connection wall, the air having heat around the agitating motor passes through the ventilation passage and reaches the lower surface of the bottom wall of the accommodation part of the electrical component accommodation box. As a result, it is possible to further prevent the inside of the housing portion from being cooled and condensed.

Has a stirrer motor 40 and a protrusion 31c that is integral with the outer peripheral wall of the housing part 30a of the electrical component housing box 30. Below, this beer dispenser 10 is explained in full detail.

図１及び図２に示すように、ビールディスペンサ１０は、ハウジング１１の上側に冷却水を貯える冷却水槽２０と、ハウジング１１内の下側の機械室に蒸発管５１を除く冷凍装置５０とを備え、ハウジング１１の上面開口が蓋１２により覆われている。また、ビールディスペンサ１０は、ハウジング１１の前壁上部に飲料を注出するための２つの注出コック１３を備えている。   As shown in FIGS. 1 and 2, the beer dispenser 10 includes a cooling water tank 20 that stores cooling water on the upper side of the housing 11, and a refrigeration apparatus 50 that excludes the evaporation pipe 51 in the lower machine chamber in the housing 11. The upper surface opening of the housing 11 is covered with a lid 12. Further, the beer dispenser 10 includes two pouring cocks 13 for pouring a beverage on the upper front wall of the housing 11.

図２、図３及び図７に示すように、冷却水槽２０はビール等の飲料を冷却するための冷却水を貯えるためのものであり、上面が開口して前後方向の幅が左右方向の幅より長い略直方体形状をしている。冷却水槽２０内の冷却水は、図示しないオーバーフローパイプにより所定の水位Ｌを超えないようになっている。図２に示すように、冷却水槽２０の上面開口の後部には、電装部品収容箱３０が設けられている。   As shown in FIGS. 2, 3 and 7, the cooling water tank 20 is for storing cooling water for cooling beverages such as beer, and the top surface is open and the width in the front-rear direction is the width in the left-right direction. It has a longer rectangular parallelepiped shape. The cooling water in the cooling water tank 20 does not exceed a predetermined water level L by an overflow pipe (not shown). As shown in FIG. 2, an electrical component storage box 30 is provided at the rear of the upper surface opening of the cooling water tank 20.

電装部品収容箱３０は、冷凍装置５０等の作動を制御する制御基板等の電装部品１４を収容する上面が開口した箱形状をした収容部３０ａと、撹拌モータ４０を支持する支持板部３１とを樹脂部材により一体的に形成したものである。図２〜図４に示すように、収容部３０ａの上側からみた形状は、前側部の中央が凹んだ略コ字形をしており、冷却水槽２０の後壁上端と左右両側壁の後部上端に支持されている。図２、図４及び図５に示すように、支持板部３１は、収容部３０ａの凹んだ部分の前壁と両側壁の各下端部から下方に延びる接続壁部３０ｂの下端部から冷却水槽２０の上側中央部に向けて水平方向に延出して、収容部３０ａの底壁より低い位置に設けられている。   The electrical component storage box 30 includes a box-shaped storage portion 30a having an open upper surface for storing the electrical component 14 such as a control board that controls the operation of the refrigeration apparatus 50, and the like, and a support plate portion 31 that supports the stirring motor 40. Are integrally formed of a resin member. As shown in FIGS. 2-4, the shape seen from the upper side of the accommodating part 30a is the substantially U shape where the center of the front side part was dented, and it is on the rear wall upper end of the cooling water tank 20, and the rear upper end of both right and left side walls. It is supported. As shown in FIGS. 2, 4, and 5, the support plate portion 31 is a cooling water tank from the lower end portion of the connecting wall portion 30 b that extends downward from the front wall of the recessed portion of the housing portion 30 a and the lower end portions of the both side walls. It extends in the horizontal direction toward the upper center portion of 20 and is provided at a position lower than the bottom wall of the accommodating portion 30a.

図２及び図６に示すように、支持板部３１の下面には、後述する網状筒部材４３が傾いたり水平方向に移動しないようにするための係止突起３１ａが設けられている。また、支持板部３１の下面の周部と両側部とには、支持板部３１を補強するために下方に突出して形成された補強用リブ３１ｂが形成されている。   As shown in FIGS. 2 and 6, a locking projection 31 a is provided on the lower surface of the support plate portion 31 to prevent the mesh tube member 43 described later from tilting or moving in the horizontal direction. Reinforcing ribs 31 b are formed on the periphery and both sides of the lower surface of the support plate 31 so as to protrude downward to reinforce the support plate 31.

図２〜図４に示すように、支持板部３１の上面には、撹拌モータ４０がボルトにより固定されている。撹拌モータ４０の外周には、支持板部３１にボルトで固定するための４つの固定部４０ａが設けられている。撹拌モータ４０の回転軸４１は、支持板部３１を貫通して冷却水槽２０の下部位置まで延びている。回転軸４１の下端には、冷却水槽２０内の冷却水を撹拌する撹拌羽根４２が取り付けられている。図５に示すように、支持板部３１の上面の撹拌モータ４０を固定した位置には、突条３１ｃが一体的に形成されている。突条３１ｃは、撹拌モータ４０を作動させたときに発生する熱を収容部３０ａ内に伝達するためのものである。突条３１ｃは、撹拌モータ４０の収容部３０ａ側となる一部として収容部３０ａ側の略半部の周縁部を支持しており、電装部品収容箱３０の収容部３０ａの外周壁として前壁に一体的になるように接続されている。図４及び図５に示すように、支持板部３１の上面の撹拌モータ４０の固定部４０ａが設けられている位置には、固定用突部３１ｄが一体的に設けられている。固定用突部３１ｄは、突条３１ｃとともに撹拌モータ４０を支持板部３１の上面から少し上側で支持するものである。   As shown in FIGS. 2 to 4, a stirring motor 40 is fixed to the upper surface of the support plate portion 31 with a bolt. On the outer periphery of the stirring motor 40, four fixing portions 40a for fixing to the support plate portion 31 with bolts are provided. The rotating shaft 41 of the stirring motor 40 extends through the support plate portion 31 to the lower position of the cooling water tank 20. A stirring blade 42 for stirring the cooling water in the cooling water tank 20 is attached to the lower end of the rotating shaft 41. As shown in FIG. 5, a protrusion 31 c is integrally formed at a position where the stirring motor 40 is fixed on the upper surface of the support plate portion 31. The protrusion 31c is for transmitting heat generated when the agitation motor 40 is operated into the accommodating portion 30a. The protrusion 31c supports a peripheral portion of a substantially half portion on the housing portion 30a side as a part on the housing portion 30a side of the stirring motor 40, and a front wall as an outer peripheral wall of the housing portion 30a of the electrical component housing box 30 To be integrated with each other. As shown in FIGS. 4 and 5, a fixing protrusion 31 d is integrally provided at a position where the fixing portion 40 a of the agitation motor 40 is provided on the upper surface of the support plate portion 31. The fixing protrusion 31d supports the stirring motor 40 together with the protrusion 31c slightly above the upper surface of the support plate 31.

また、図２及び図６に示すように、電装部品収容箱３０の収容部３０ａの底壁下面には、隙間を設けて冷却水遮蔽板３２が取り付けられている。冷却水遮蔽板３２は、収容部３０ａの底壁下面の下側に隙間を設けて配置された遮蔽板部３２ａと、遮蔽板部３２ａの左右両端部と後端部で上側に折り曲げられた垂直部３２ｂと、垂直部３２ｂの上端で水平方向外側に折り曲げられたフランジ部３２ｃとからなり、板金部材を折り曲げて形成したものである。冷却水遮蔽板３２は、フランジ部３２ｃを電装部品収容箱３０の収容部３０ａの底壁下面と、冷却水槽２０の左右両側壁の後部上端及び後壁上端とで挟んで支持されている。冷却水遮蔽板３２は、冷却水槽２０内の冷却水が収容部３０ａの底壁下面に直接付着するのを防ぐものである。また、冷却水遮蔽板３２は、収容部３０ａとの間の空気により収容部３０ａの底壁下面に冷却水槽２０内の冷却水による冷熱が伝達されるのを抑制するものである。   As shown in FIGS. 2 and 6, a cooling water shielding plate 32 is attached to the lower surface of the bottom wall of the housing part 30 a of the electrical component housing box 30 with a gap. The cooling water shielding plate 32 includes a shielding plate portion 32a arranged with a gap below the lower surface of the bottom wall of the housing portion 30a, and a vertical bent upward at the left and right end portions and the rear end portion of the shielding plate portion 32a. It consists of a portion 32b and a flange portion 32c bent outward in the horizontal direction at the upper end of the vertical portion 32b, and is formed by bending a sheet metal member. The cooling water shielding plate 32 is supported by sandwiching the flange portion 32 c between the bottom wall lower surface of the housing portion 30 a of the electrical component housing box 30 and the rear upper end and rear wall upper end of the left and right side walls of the cooling water tank 20. The cooling water shielding plate 32 prevents the cooling water in the cooling water tank 20 from directly adhering to the lower surface of the bottom wall of the housing portion 30a. Further, the cooling water shielding plate 32 suppresses the transmission of cold heat from the cooling water in the cooling water tank 20 to the lower surface of the bottom wall of the housing portion 30a by the air between the housing portion 30a.

図２に示すように、電装部品収容箱３０の上側には、カバー３３が設けられている。カバー３３は、電装部品収容箱３０の収容部３０ａの上面開口を覆うとともに、支持板部３１に固定した撹拌モータ４０の上側及び前側を覆っている。カバー３３は、収容部３０ａ内に冷却水や埃が流入するのを防ぎ、撹拌モータ４０に冷却水や埃が付着するのを防ぐためのものである。   As shown in FIG. 2, a cover 33 is provided on the upper side of the electrical component storage box 30. The cover 33 covers the upper surface opening of the housing part 30 a of the electrical component housing box 30 and covers the upper side and the front side of the stirring motor 40 fixed to the support plate part 31. The cover 33 is for preventing cooling water and dust from flowing into the accommodating portion 30a and preventing the cooling water and dust from adhering to the stirring motor 40.

また、図２及び図５に示すように、収容部３０ａと支持板部３１とを接続する接続壁部３０ｂには、撹拌モータ４０の周囲の空気を収容部３０ａの底壁下面側に送出するための貫通孔よりなる送風通路３０ｃが形成されている。撹拌モータ４０を作動させたときに熱を持った周囲の空気は、送風通路３０ｃを通過して収容部３０ａの底壁下面と冷却水遮蔽板３２との間に送出される。これにより、収容部３０ａ内は、冷却水槽２０内の冷却水による冷熱が伝達されるのをさらに抑制されている。   As shown in FIGS. 2 and 5, the air around the agitation motor 40 is sent to the lower surface of the bottom wall of the housing portion 30 a to the connection wall portion 30 b that connects the housing portion 30 a and the support plate portion 31. A ventilation passage 30c made of a through hole is formed. The ambient air having heat when the agitating motor 40 is operated passes through the blower passage 30c and is sent between the lower surface of the bottom wall of the accommodating portion 30a and the cooling water shielding plate 32. Thereby, in the accommodating part 30a, it is further suppressed that the cold heat by the cooling water in the cooling water tank 20 is transmitted.

図２、図３及び図７に示すように、冷却水槽２０内には、撹拌羽根４２を囲うように円筒形の網状筒部材４３が設けられている。網状筒部材４３は、撹拌羽根４２の回転により発生する渦を小さくすることで渦へのエアの巻き込み音を抑制するとともに、撹拌羽根４２が蒸発管５１から剥離した氷に接触して破損したり、撹拌羽根４２が氷を噛んでロックするのを防ぐためのものである。網状筒部材４３の下端部は冷却水槽２０の底面に一体的に形成された４つの支持突部２０ａに支持されている。また、網状筒部材４３は、上端が支持板部３１の下面に当接しており、上端部の内周面が支持板部３１の係止突起３１ａに係止している。網状筒部材４３は、上下方向及び水平方向に移動しないように冷却水槽２０内に取り付けられている。   As shown in FIGS. 2, 3, and 7, a cylindrical reticulated tube member 43 is provided in the cooling water tank 20 so as to surround the stirring blade 42. The net-like cylindrical member 43 reduces the vortex generated by the rotation of the stirring blade 42 to suppress the entrainment sound of air into the vortex, and the stirring blade 42 may be damaged due to contact with the ice peeled from the evaporation pipe 51. This is for preventing the stirring blade 42 from biting and locking the ice. The lower end portion of the net-like cylindrical member 43 is supported by four support protrusions 20 a formed integrally with the bottom surface of the cooling water tank 20. In addition, the upper end of the net-like cylindrical member 43 is in contact with the lower surface of the support plate portion 31, and the inner peripheral surface of the upper end portion is engaged with the engagement protrusion 31 a of the support plate portion 31. The net-like cylinder member 43 is attached in the cooling water tank 20 so as not to move in the vertical direction and the horizontal direction.

図２、図３及び図７に示すように、冷却水槽２０には、網状筒部材４３の外周側に冷凍装置５０の蒸発管５１が螺旋状に巻回されている。冷凍装置５０は、圧縮機５２により圧縮した冷媒ガスを凝縮器により冷却して液化させ、この液化冷媒を膨張弁を通して冷却水槽２０内の蒸発管５１に導き、蒸発管５１で気化させ冷却水槽２０内の冷却水を冷却する。このとき、冷却水槽２０内の冷却水の一部は蒸発管５１の周囲で凍結して氷となる。螺旋状の蒸発管５１は、図７に示すように、前後方向の幅が左右方向の幅より長く上側から見たときの形状が小判形に巻回されている。蒸発管５１の下端部は、冷却水槽２０の底面に設けられた６つの蒸発管支持脚部２０ｂにより支持されている。各蒸発管支持脚部２０ｂは、螺旋状に巻回された蒸発管５１の下端の高さに応じた高さで蒸発管５１を支持している。また、蒸発管５１の外周側には、蒸発管５１の周囲の氷の厚さを検知し、氷を所定の厚さに維持するための氷センサ５３が取り付けられている。   As shown in FIGS. 2, 3, and 7, in the cooling water tank 20, the evaporation pipe 51 of the refrigeration apparatus 50 is spirally wound around the outer peripheral side of the mesh tube member 43. The refrigeration apparatus 50 cools and liquefies the refrigerant gas compressed by the compressor 52 by a condenser, guides the liquefied refrigerant to the evaporation pipe 51 in the cooling water tank 20 through the expansion valve, and vaporizes the refrigerant gas in the evaporation pipe 51. Cool the cooling water inside. At this time, a part of the cooling water in the cooling water tank 20 is frozen around the evaporation pipe 51 to become ice. As shown in FIG. 7, the spiral evaporation tube 51 has a width in the front-rear direction longer than the width in the left-right direction and is wound in an oval shape when viewed from above. The lower end portion of the evaporation pipe 51 is supported by six evaporation pipe support legs 20 b provided on the bottom surface of the cooling water tank 20. Each of the evaporating tube support legs 20b supports the evaporating tube 51 at a height corresponding to the height of the lower end of the evaporating tube 51 wound spirally. Further, an ice sensor 53 for detecting the thickness of ice around the evaporation tube 51 and maintaining the ice at a predetermined thickness is attached to the outer peripheral side of the evaporation tube 51.

蒸発管５１には、巻き線方向の間隔を所定間隔に保つように保持して冷却水槽２０内に取り付けるための２本のホルダ５４が取り付けられている。各ホルダ５４は、上側から見た形状が略十字形をした樹脂製の柱状部材よりなる。各ホルダ５４は、小判形をした螺旋状に巻回された蒸発管５１の前後方向の中央より少し後側の内周の両側位置で冷却水槽２０内に立設している。各ホルダ５４には、螺旋状の蒸発管５１の巻き線方向の間隔を所定間隔に保つように保持する略Ｃ字形をした８つの保持部５４ａが上下方向に所定間隔を設けて形成されている。各ホルダ５４の下端は、冷却水槽２０の底面に一体的に形成された一対の円柱状の位置決め突部２０ｃに係止して前後及び左右方向にずれないように位置決めされている。各ホルダ５４の上端は、支持板部３１の下面に一体的に形成された補強用リブ３１ｂに係止して左右方向にずれないように位置決めされている。このように、蒸発管５１は、冷却水槽２０の底部と支持板部３１の下面とでホルダ５４を挟持して取り付けられている。   Two holders 54 are attached to the evaporation pipe 51 so as to be held in the cooling water tank 20 while being kept at a predetermined interval in the winding direction. Each holder 54 is made of a resin-made columnar member having a substantially cross shape when viewed from above. Each holder 54 is erected in the cooling water tank 20 at both positions on the inner periphery slightly behind the center in the front-rear direction of the evaporating pipe 51 wound in an oval shape. Each holder 54 is formed with approximately C-shaped holding portions 54a that hold the spiral evaporation tube 51 in the winding direction so as to keep a predetermined interval in the vertical direction. . The lower end of each holder 54 is positioned so as not to be displaced in the front-rear and left-right directions by engaging with a pair of columnar positioning projections 20 c formed integrally with the bottom surface of the cooling water tank 20. The upper end of each holder 54 is positioned so as not to be displaced in the left-right direction by being engaged with a reinforcing rib 31b formed integrally with the lower surface of the support plate portion 31. Thus, the evaporation pipe 51 is attached with the holder 54 sandwiched between the bottom of the cooling water tank 20 and the lower surface of the support plate 31.

図２、図３及び図７に示すように、冷却水槽２０内には、螺旋状の蒸発管５１の外周側で冷却水槽２０の内周壁に沿ってビール等の飲料を冷却するための飲料冷却管６０が螺旋状に巻回されている。この実施形態においては、２つの注出コック１３に対応するように、２つの飲料冷却管６０が同心的に２重の螺旋状に配置されている。飲料冷却管６０の流入端部はハウジング１１の右側壁上部に設けられた継手部によりビール樽から導出されるビールホースと接続可能となっており、飲料冷却管６０の流出端部はハウジング１１の前壁上部の注出コック１３に接続されている。   As shown in FIGS. 2, 3, and 7, in the cooling water tank 20, beverage cooling for cooling beverages such as beer along the inner peripheral wall of the cooling water tank 20 on the outer peripheral side of the spiral evaporation pipe 51. A tube 60 is wound spirally. In this embodiment, the two beverage cooling pipes 60 are concentrically arranged in a double spiral so as to correspond to the two pouring cocks 13. The inflow end of the beverage cooling pipe 60 can be connected to a beer hose led out from the beer barrel by a joint provided at the upper right side wall of the housing 11, and the outflow end of the beverage cooling pipe 60 is connected to the housing 11. It is connected to a pouring cock 13 at the top of the front wall.

上記のように構成したビールディスペンサ１０の作動について説明する。ビールディスペンサ１０の電源をオンにすると、撹拌羽根４２が撹拌モータ４０により回転して、冷却水槽２０内の冷却水が撹拌される。また、冷凍装置５０が作動して、圧縮機５２により圧縮された冷媒ガスが凝縮器により冷却されて液化し、この液化冷媒が膨張弁を通って冷却水槽２０内の蒸発管５１に導かれ、冷却水槽２０内の冷却水が蒸発管５１で気化する液化冷媒により冷却される。このとき、冷却水槽２０内の冷却水の一部は蒸発管５１の周囲で徐々に冷却されて凍結して氷Ｉとなる。冷却水槽２０内の冷却水が十分に冷却された状態で、注出コック１３のレバーを傾動させると、図示しないビール樽から圧送されるビールが飲料冷却管６０を通過するときに冷却水と熱交換により冷却されて注出コック１３から注ぎ出される。   The operation of the beer dispenser 10 configured as described above will be described. When the power of the beer dispenser 10 is turned on, the stirring blade 42 is rotated by the stirring motor 40 and the cooling water in the cooling water tank 20 is stirred. Further, when the refrigeration apparatus 50 is activated, the refrigerant gas compressed by the compressor 52 is cooled and liquefied by the condenser, and this liquefied refrigerant is led to the evaporation pipe 51 in the cooling water tank 20 through the expansion valve, The cooling water in the cooling water tank 20 is cooled by the liquefied refrigerant vaporized in the evaporation pipe 51. At this time, a part of the cooling water in the cooling water tank 20 is gradually cooled around the evaporation pipe 51 and frozen to become ice I. When the lever of the pouring cock 13 is tilted in a state where the cooling water in the cooling water tank 20 is sufficiently cooled, when the beer fed from a beer barrel (not shown) passes through the beverage cooling pipe 60, the cooling water and heat It is cooled by replacement and poured out from the pouring cock 13.

上記のように構成したビールディスペンサ１０においては、部品点数及び取付けのための作業工数を減らしてコストダウンを図ることを目的として、電装部品収容箱３０は電装部品を収容する収容部３０ａと撹拌モータ４０を支持する支持板部３１とを樹脂部材により一体成形したものである。また、このビールディスペンサ１０は、装置を小型化するにあたって冷却水槽２０の容量を小さくしている。冷却水槽２０の容量を小さくすると、電装部品収容箱３０の収容部３０ａの底壁下面が冷却水槽２０の冷却水の水面に近くなり、電装部品収容箱３０の収容部３０ａ内は、冷却水槽２０内の冷却水の冷熱により低温となって結露しやすくなっていた。また、電装部品収容箱３０の収容部３０ａ内は、その底壁下面に撹拌羽根４２の撹拌によって波立つ冷却水が付着して低温となって結露しやすくなっていた。   In the beer dispenser 10 configured as described above, for the purpose of reducing costs by reducing the number of parts and the number of work steps for installation, the electrical component storage box 30 includes a storage portion 30a for storing electrical components and a stirring motor. The support plate portion 31 that supports 40 is integrally formed of a resin member. Moreover, this beer dispenser 10 makes the capacity | capacitance of the cooling water tank 20 small in size reduction of an apparatus. When the capacity of the cooling water tank 20 is reduced, the bottom wall lower surface of the housing part 30a of the electrical component housing box 30 is close to the water surface of the cooling water in the cooling water tank 20, and the inside of the housing part 30a of the electrical component housing box 30 is the cooling water tank 20. The temperature of the inside cooling water was low, and condensation was likely to occur. In addition, in the housing part 30a of the electrical component housing box 30, the cooling water that swells due to the stirring of the stirring blades 42 adheres to the bottom of the bottom wall, so that the temperature becomes low and condensation easily occurs.

そこで、上記のように構成したビールディスペンサ１０においては、支持板部３１の上面には撹拌モータ４０を乗載するとともに電装部品収容箱３０の収容部３０ａの外周壁として前壁と一体的となる突条３１ｃを設けたので、撹拌モータ４０から発生する熱を支持板部３１で拡散させることなく突条３１ｃにより電装部品収容箱３０の収容部３０ａ内に伝達して、収容部３０ａ内が冷却水の冷熱により低温となって結露するのを防ぐことができる。また、突条３１ｃは撹拌モータ４０の電装部品収容箱３０の収容部３０ａ側の略半部を乗載するようにしているので、撹拌モータ４０から発生する熱が電装部品収容箱３０の収容部３０ａと反対側に伝達されるのを防ぐことができ、撹拌モータ４０から発生する熱の伝達効率を上げることができる。   Therefore, in the beer dispenser 10 configured as described above, the stirring motor 40 is mounted on the upper surface of the support plate portion 31 and is integrated with the front wall as the outer peripheral wall of the housing portion 30a of the electrical component housing box 30. Since the protrusion 31c is provided, the heat generated from the agitation motor 40 is transmitted to the accommodation part 30a of the electrical component accommodation box 30 by the protrusion 31c without being diffused by the support plate part 31, and the inside of the accommodation part 30a is cooled. It is possible to prevent condensation due to low temperature due to cold water. Further, since the protrusion 31c is mounted on a substantially half portion of the electrical component storage box 30 of the stirring motor 40 on the side of the storage portion 30a, the heat generated from the stirring motor 40 is received by the storage portion of the electrical component storage box 30. It is possible to prevent the heat from being transmitted to the side opposite to 30a, and to increase the efficiency of transferring heat generated from the stirring motor 40.

また、上記のように構成したビールディスペンサ１０においては、電装部品収容箱３０の収容部３０ａの底壁下面には隙間を設けて冷却水遮蔽板３２を取り付けているので、冷却水槽２０内の冷却水が冷却水遮蔽板３２により電装部品収容箱３０の収容部３０ａの底壁下面に付着するのを防ぐことができる。また、電装部品収容箱３０の収容部３０ａの底壁下面は、冷却水遮蔽板３２との間の空気により冷却水槽２０内の冷却水の冷熱が伝わりにくくなっている。このように、冷却水遮蔽板３２は、電装部品収容箱３０の収容部３０ａ内が低温となって結露するのをさらに防ぐことができる。   Further, in the beer dispenser 10 configured as described above, the cooling water shielding plate 32 is attached to the bottom wall lower surface of the housing part 30a of the electrical component housing box 30 so that the cooling water shielding plate 32 is attached. Water can be prevented from adhering to the lower surface of the bottom wall of the housing part 30 a of the electrical component housing box 30 by the cooling water shielding plate 32. In addition, the lower surface of the bottom wall of the housing portion 30 a of the electrical component housing box 30 is difficult to transmit the cooling heat of the cooling water in the cooling water tank 20 by the air between the cooling water shielding plate 32. In this way, the cooling water shielding plate 32 can further prevent the inside of the housing part 30a of the electrical component housing box 30 from becoming low temperature and causing condensation.

また、上記のように構成したビールディスペンサ１０においては、支持板部３１は、電装部品収容箱３０の収容部３０ａの凹部の前壁と側壁とから下方に延びる接続壁部３０ｂの下端から冷却水槽２０の中央部に延出して、電装部品収容箱３０の収容部３０ａの底壁より下側に設けられており、この接続壁部３０ｂには、撹拌モータ４０の周囲の熱を持った空気を収容部３０ａの底壁下面と冷却水遮蔽板３２との間に送るための貫通孔よりなる送風通路３０ｃを設けたので、撹拌モータ４０の周囲の熱を持った空気が送風通路３０ｃを通過して収容部３０ａの底壁下面と冷却水遮蔽板３２との間に送られるようになり、収容部３０ａ内が低温となって結露するのをさらに防ぐことができる。   Moreover, in the beer dispenser 10 comprised as mentioned above, the support plate part 31 is a cooling water tank from the lower end of the connection wall part 30b extended below from the front wall and side wall of the recessed part of the accommodating part 30a of the electrical component accommodating box 30. 20 is provided below the bottom wall of the housing part 30a of the electrical component housing box 30, and air having heat around the stirring motor 40 is supplied to the connecting wall part 30b. Since the air passage 30c made of a through hole for sending between the lower surface of the bottom wall of the accommodating portion 30a and the cooling water shielding plate 32 is provided, the air having the heat around the stirring motor 40 passes through the air passage 30c. Thus, it can be sent between the lower surface of the bottom wall of the accommodating part 30a and the cooling water shielding plate 32, and it is possible to further prevent the inside of the accommodating part 30a from becoming low temperature and condensing.

また、上記のように構成したビールディスペンサ１０においては、電装部品収容箱３０の上側にはカバー３３を設けており、このカバー３３は収容部３０ａの上面開口を覆うとともに、支持板部３１に固定した撹拌モータ４０の上側及び前側を覆っている。撹拌モータ４０は、カバー３３に覆われていることで高温となりやすいが、突条３１ｃと固定用突部３１ｄとにより支持板部３１の上面より少し上側で隙間を設けて支持されているので、回転軸４１を挿通する開口から流入する冷却水の冷熱により高温となりにくくなっている。   Further, in the beer dispenser 10 configured as described above, the cover 33 is provided on the upper side of the electrical component storage box 30, and the cover 33 covers the upper surface opening of the storage portion 30 a and is fixed to the support plate portion 31. The upper side and the front side of the agitating motor 40 are covered. The stirring motor 40 is likely to become high temperature because it is covered with the cover 33, but is supported by the protrusion 31c and the fixing protrusion 31d with a gap slightly above the upper surface of the support plate 31. It becomes difficult to reach a high temperature due to the cooling heat of the cooling water flowing from the opening through which the rotary shaft 41 is inserted.

上記の実施形態においては、冷却水遮蔽板３２の遮蔽板部３２ａは、収容部３０ａの底壁下面の下側で水平となっているが、本発明はこれに限られるものでなく、遮蔽板部３２ａの前側部が上側となるように傾斜させれば、冷却水槽２０内で撹拌羽根４２による撹拌によって波立つ冷却水が遮蔽板部３２ａの上面に侵入しにくくすることができる。なお、このようにしたときには、冷却水遮蔽板３２の後端部に遮蔽板部３２ａの上面に侵入した冷却水を排出する排水孔を形成すれば、遮蔽板部３２ａの上面に侵入した冷却水が貯まることなく排出することができる。   In the above embodiment, the shielding plate portion 32a of the cooling water shielding plate 32 is horizontal below the bottom surface of the bottom wall of the accommodating portion 30a. However, the present invention is not limited to this, and the shielding plate. If the front side portion of the portion 32a is inclined so as to be on the upper side, it is possible to make it difficult for the cooling water that rippls due to stirring by the stirring blade 42 in the cooling water tank 20 to enter the upper surface of the shielding plate portion 32a. In this case, if a drainage hole for discharging the cooling water that has entered the upper surface of the shielding plate portion 32a is formed at the rear end portion of the cooling water shielding plate 32, the cooling water that has entered the upper surface of the shielding plate portion 32a. Can be discharged without accumulating.
