Description

【0001】
本発明は、密閉型の水タンクからの飲料水を使用して温水機等の被給水機器に給水するようにした飲料用給水装置に関する。
【0002】
【従来技術】
従来、水タンクから温水機等の被給水機器に給水する飲料用給水装置は、図8に示されるように、温水機等の置台を兼ねた被給水機器aを載置する置台本体bに水タンクcを収納し、この水タンクcの上部に設けられた給水口dより例えばポリタンクeを用いて給水し、この給水された水タンクc内の飲料水を被給水機器aに供給するようにしていた。しかし、このような飲料用給水装置によれば、水タンクcは密閉式ではなく常に空気に触れ、このため数日の放置でも雑菌が繁殖しやすく非衛生的であった。そこで、この給水口dを有する水タンクcに代えて空気に触れない密閉式のバッグインボックス方式の水タンクが用いられるようになった。
【0003】
【発明が解決しようとする課題】
しかし、このバッグインボックス方式の水タンクの水取出口に被給水機器aに飲料水を導くための入口ホースを接続する際に水タンクの水取出口付近の飲料水が空気に触れて雑菌を含んだ飲料水となって被給水機器aに供給されてしまう恐れがあった。
【0004】
本発明は、このような点に鑑みなされたもので、空気に触れて雑菌を含んだ飲料水を排出して雑菌の少ない飲料水を被給水機器に供給できるようにした飲料用給水装置を提供することを目的とする。
【0005】
【課題を解決するための手段】
請求項1記載の飲料用給水装置は、前面に開口部を有し箱状に形成され置台を兼ねた置台本体と、この置台本体の底板上に取付けられた重量検知手段と、前記置台本体に収納され前記開口部より出し入れ自在に設けられた台車と、水取出口を有する密閉型の水タンクと、一端側を前記水タンクの水取出口に接続される接続カプラを有するとともに他端側をポンプの入口側に接続される入口ホースと、一端側を前記ポンプの出口側に接続し他端側を分岐して一方を被給水機器に接続するとともに、他方を空気に触れた水を排水電磁弁を介して排水タンクに排出する出口ホースとを備えた飲料用給水装置において、前記水タンクセット時、前記台車を前記開口部よりより引き出して水タンクを前記台車に載置するとともに水タンクの水取出口に前記入口ホースの接続カプラを接続し、その後、前記台車を前記置台本体に押し戻して置台本体内に収納した時に前記重量検知手段が水タンクの重量を検知して一定時間前記ポンプを動作させるとともに、前記排水電磁弁を開放して前記水取出口付近の空気に触れた水を前記出口ホースから排水タンクへ排出させるようにたものである。
【0006】
そして、この構成により、空気に触れて雑菌を含んだ飲料水を排出して雑菌の少ない飲料水を被給水機器に供給できる。
【0007】
【発明の実施の形態】
以下、本発明の一実施の形態を図面を参照して説明する。
【0008】
【実施例】
図1に、飲料用給水装置の被給水機器に温水機を適用した構成図を示し、1は扉2を有した置台を兼ねた置台本体で、この置台本体1の上面置台部分には前面にカップステーション3を備えた被給水機器となる温水機4が載置されている。そして、この置台本体1は図2に示されるように扉2に対向した前面に開口部5を有した箱状に形成されている。また、置台本体1の底板6には重量検知手段7が配設されている。8は台車で、この台車8は上方を開放した皿状に形成され重量検知手段7に対向した位置に重量検知用穴9と移動用の複数のローラ10を有し置台本体1の開口部5から置台本体1内に対して出し入れ自在となっている。
【0009】
11はバッグインボックス方式の密閉式の水タンクで、この水タンク11は予め天然水等の飲料水が収納され一側面下部には図示しない逆止弁を有した水取出口12を有し置台本体1内に収納されるようになっている。13は入口ホースで、この入口ホース13は一端側に水タンク11の水取出口12に接続される接続カプラ14を有し他端側はポンプ15の入口側に接続されるようになっている。16は出口ホースで、この出口ホース16はポンプ15の出口側に接続されるとともに途中から分岐して、一方は図5に示される温水機に適用した被給水機器4にメス側継手17を介して接続され、他方は排水電磁弁18を介して置台本体1内に収納された排水タンク19に接続されるようになっている。
【0010】
置台本体1上に載置された温水機に適用した被給水機器4は、出口ホース16のメス側継手17と給水電磁弁20を有する接続パイプ21のオス側継手22との結合により接続される接続パイプ21を有し、この接続パイプ21を介して飲料水を導いて貯留される湯タンク23を有している。そして、この湯タンク23には水タンク11から導かれた飲料水の水位を一定の水位に保つフロートスイッチ24と、水タンク11から導かれた飲料水を沸き上げるヒータ25と、この沸き上げられた湯を湯電磁弁26を介して抽出する抽出パイプ27とが設けられている。
【0011】
次に、本実施の形態の作用を説明する。
【0012】
水タンク11を置台本体1内の台車8に最初にセットする時や水タンク11内の飲料水が少なくなり水タンク11を交換する時に、まず、図7に示されるように台車8を置台本体1の開口部5より手前に台車8全長の1/3程度をローラ10を介して引き出し水タンク11を台車8上に載置する。そして、この状態で入口ホース13の接続カプラ14を水タンク11の水取出口12に接続する。この時重量検知手段7は図6のタイムチャート図に示されるようにオフ信号を検出している。
【0013】
次に、水取出口12に接続カプラ1が接続されたら台車8を図4に示されるように押し戻して置台本体1内に収納させる。そして、この状態で水タンク11の重量が重量検知用穴9を通して重量検知手段7に作用し図6のタイムチャート図に示されるように重量検知手段7は水タンク11内に所定の飲料水がある限りオン信号を発しつづける。そして、このオン信号により排水電磁弁18とポンプ15が同時にオンし図6のタイムチャート図に示されるように一定時間排水電磁弁18を開放するとともにポンプ15を駆動して取出口12付近の空気に触れた飲料水を排水タンク19へ排出させ被給水機器4からの給水要求に備えられる。したがって、この排水動作により水取出口12付近の空気に触れた雑菌を含んだ飲料水は温水機に適用された被給水機器4に給水されることなく衛生的である。
【0014】
一方、温水機に適用された被給水機器4はヒータ25の通電により沸き上げられ、この沸き上げられた温水は湯電磁弁26を開放して飲料用の湯として利用される。そして、この湯の利用により湯タンク23内の水位が所定量以下に低下するとフロートスイッチ24から給水要求信号を給水電磁弁20および図6のタイムチャート図に示されるようにポンプ15に発し、この給水要求信号に基づいて給水電磁弁20が開かれるとともに、ポンプ15が駆動して水位低下分に相当する量の飲料水を水タンク11内から入口ホース13、出口ホース16、接続パイプ20を通じて湯タンク23内に飲料水が給水される。
【0015】
なお、被給水機器4は温水機の実施例で説明したがこれに限らず冷水機に用いても良い。
【0016】
【発明の効果】
請求項1記載によれば、空気に触れて雑菌を含んだ飲料水を排出して雑菌の少ない飲料水を被給水機器に供給できる。

[0007]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
[0008]
【Example】
FIG. 1 shows a configuration diagram in which a water heater is applied to a water-supplied device of a drinking water supply device. Reference numeral 1 denotes a table body that also serves as a table having a door 2, and an upper table part of the table body 1 has a front surface. A water heater 4 serving as a water-supplied device having a cup station 3 is mounted. The table main body 1 is formed in a box shape having an opening 5 on the front surface facing the door 2 as shown in FIG. A weight detecting means 7 is provided on the bottom plate 6 of the table main body 1. Reference numeral 8 denotes a trolley. The trolley 8 is formed in a dish shape with an open top, and has a hole 9 for weight detection and a plurality of rollers 10 for movement at a position facing the weight detection means 7. From the table body 1 can be freely taken in and out.
[0009]
Reference numeral 11 denotes a closed-type water tank of a bag-in-box type. The water tank 11 previously stores drinking water such as natural water and has a water outlet 12 having a check valve (not shown) at a lower part of one side. It is designed to be stored in the main body 1. Reference numeral 13 denotes an inlet hose. The inlet hose 13 has a connecting coupler 14 connected to the water outlet 12 of the water tank 11 on one end side, and the other end side is connected to the inlet side of the pump 15. . Reference numeral 16 denotes an outlet hose, which is connected to the outlet side of the pump 15 and branches off in the middle. One of the outlet hoses 16 is connected to the water supply apparatus 4 applied to the water heater shown in FIG. The other is connected to a drainage tank 19 housed in the table body 1 via a drainage electromagnetic valve 18.
[0010]
The water supply device 4 applied to the water heater mounted on the table main body 1 is connected by coupling the female joint 17 of the outlet hose 16 and the male joint 22 of the connection pipe 21 having the water supply solenoid valve 20. It has a connection pipe 21 and a hot water tank 23 for guiding and storing drinking water through the connection pipe 21. The hot water tank 23 has a float switch 24 for keeping the level of the drinking water led from the water tank 11 at a constant level, a heater 25 for boiling the drinking water led from the water tank 11, An extraction pipe 27 for extracting hot water via a hot water electromagnetic valve 26 is provided.
[0011]
Next, the operation of the present embodiment will be described.
[0012]
When the water tank 11 is first set on the trolley 8 in the pedestal body 1 or when the drinking water in the water tank 11 is reduced and the water tank 11 is replaced, first, as shown in FIG. About 1/3 of the entire length of the trolley 8 is pulled out through the roller 10 in front of the opening 5 of 1, and the water tank 11 is placed on the trolley 8. Then, in this state, the connection coupler 14 of the inlet hose 13 is connected to the water outlet 12 of the water tank 11. At this time, the weight detecting means 7 detects the off signal as shown in the time chart of FIG.
[0013]
Next, when the connection coupler 1 is connected to the water outlet 12, the carriage 8 is pushed back as shown in FIG. Then, in this state, the weight of the water tank 11 acts on the weight detecting means 7 through the weight detecting hole 9, and as shown in a time chart of FIG. The ON signal continues to be emitted as long as possible. In response to the ON signal, the drain electromagnetic valve 18 and the pump 15 are simultaneously turned on, and the drain electromagnetic valve 18 is opened for a certain period of time as shown in the time chart of FIG. Is discharged to the drain tank 19 in preparation for a water supply request from the water-supplied equipment 4. Therefore, the drinking water containing the germs that has come into contact with the air near the water outlet 12 by this draining operation is sanitary without being supplied to the water-supplied equipment 4 applied to the water heater.
[0014]
On the other hand, the water-supplied equipment 4 applied to the water heater is boiled by energizing the heater 25, and the boiled hot water is used as drinking water by opening the hot water electromagnetic valve 26. When the water level in the hot water tank 23 falls below a predetermined amount due to the use of the hot water, a water supply request signal is issued from the float switch 24 to the water supply solenoid valve 20 and the pump 15 as shown in the time chart of FIG. The water supply solenoid valve 20 is opened based on the water supply request signal, and the pump 15 is driven to drive the amount of drinking water corresponding to the reduced water level from the water tank 11 through the inlet hose 13, the outlet hose 16, and the connection pipe 20. Drinking water is supplied into the tank 23.
[0015]
The water supply equipment 4 has been described in the embodiment of the water heater, but is not limited thereto, and may be used for a water heater.
[0016]
