Description

本発明は、コーヒーなどの飲料を供給する飲料供給装置および飲料供給装置を備えたカップ式飲料自動販売機に関する。   The present invention relates to a beverage supply device for supplying a beverage such as coffee and a cup-type beverage vending machine provided with the beverage supply device.

従来、この種の飲料供給装置として、カップ式飲料自動販売機に備えられた特許文献1に記載のものが知られている。この飲料供給装置は、コーヒー飲料を抽出して供給するもので、コーヒー飲料を抽出する抽出機と、この抽出機に所定量のコーヒー挽き豆および湯を供給する挽き豆供給部および湯タンクとを備え、湯タンクの湯を抽出機に供給する給湯配管と、抽出機で抽出されたコーヒー飲料をカップに供給する飲料供給管とが接続されている。抽出機は、上方に開口した原料投入口を有するシリンダと、このシリンダ内で往復動自在に設けられるとともに、飲料供給管の一端部が接続されたピストンと、シリンダの原料投入口を開閉するとともに、給湯配管の一端部が接続されたキャップとを有している。湯タンクは供給された飲料水をヒータで加熱して貯留し、コーヒー飲料抽出の都度、ポンプで加圧した湯を抽出機に供給する。   Conventionally, the thing of patent document 1 with which the cup-type drink vending machine was equipped as this kind of drink supply apparatus is known. This beverage supply device extracts and supplies coffee beverages, and includes an extractor that extracts coffee beverages, a ground bean supply unit that supplies a predetermined amount of ground coffee beans and hot water to the extractor, and a hot water tank. The hot water supply pipe which supplies the hot water of a hot water tank to an extractor, and the drink supply pipe which supplies the coffee drink extracted with the extractor to a cup are connected. The extractor is provided with a cylinder having a raw material inlet opening upward, reciprocally movable in the cylinder, a piston to which one end of a beverage supply pipe is connected, and opening and closing the raw material inlet of the cylinder. And a cap to which one end of the hot water supply pipe is connected. The hot water tank heats and stores the supplied drinking water with a heater, and supplies hot water pressurized by the pump to the extractor each time the coffee beverage is extracted.

この飲料供給装置は、次のようにして、コーヒー飲料を抽出して供給する。まず、挽き豆供給部から供給された所定量のコーヒー挽き豆をシリンダの原料投入口から投入する。次いで、原料投入口をキャップで閉鎖した後、ピストンを原料投入口側へ移動し、コーヒー挽き豆を圧縮する。そして、ポンプを所定時間駆動して湯タンクの湯を給湯配管に送り出し、所定量の湯を所定の高圧でシリンダに供給する。このようにして、シリンダ内で圧縮されているコーヒー挽き豆に高圧の湯を供給すると、コーヒー挽き豆に浸透させた湯にコーヒー成分が溶解したコーヒー飲料を抽出し、飲料供給管からカップに供給する。   This beverage supply device extracts and supplies a coffee beverage as follows. First, a predetermined amount of ground coffee beans supplied from the ground bean supply unit is charged from the raw material inlet of the cylinder. Next, after closing the raw material inlet with a cap, the piston is moved to the raw material inlet and the ground coffee beans are compressed. Then, the pump is driven for a predetermined time to send hot water in the hot water tank to the hot water supply pipe, and a predetermined amount of hot water is supplied to the cylinder at a predetermined high pressure. Thus, when high-pressure hot water is supplied to the ground coffee beans compressed in the cylinder, the coffee beverage in which the coffee components are dissolved in the hot water permeated into the ground coffee beans is extracted and supplied to the cup from the beverage supply pipe. To do.

このようにコーヒー飲料の抽出は、所定の高温、高圧の湯を抽出機のシリンダに供給し、圧縮しているコーヒー挽き豆に浸透させた湯にコーヒー成分を溶解させてコーヒー飲料を抽出する。

The cooling unit 40 has a condenser 42 installed therein, and the drinking water supplied from the water reservoir 4 is heated and stored by the exhaust heat released from the refrigerant condenser 42 compressed by the compressor 41. You may make it do.

このように、湯タンク7に冷却ユニット40の凝縮器42から放出される排熱で水リザーバ4から供給された飲料水を加熱して貯留し、コーヒー飲料を抽出するときは、湯タンク7に貯留している湯を湯ポンプ10で加圧送出して加熱装置20で再加熱(例えば、95℃)すると、コーヒー飲料を抽出するのに適した高温高圧の湯を圧縮したコーヒー挽き豆に通過させて、コーヒー挽き豆に浸透させた湯にコーヒー成分を溶解させて、最適な温度で抽出したエスプレッソコーヒー飲料を飲料供給管16からカップCに注ぐカップ式飲料自動販売機を実現することができる。さらに湯タンク7に貯留している湯を冷却ユニット40の凝縮器42から放出される排熱で加熱することにより、消費電力の低減を図ることができる。   Thus, when the drinking water supplied from the water reservoir 4 is heated and stored in the hot water tank 7 by the exhaust heat released from the condenser 42 of the cooling unit 40 and the coffee drink is extracted, When the stored hot water is pressurized and delivered by the hot water pump 10 and reheated by the heating device 20 (for example, 95 ° C.), high temperature and high pressure water suitable for extracting coffee beverage is passed through the compressed ground coffee beans. Thus, it is possible to realize a cup-type beverage vending machine in which coffee components are dissolved in hot water permeated into ground coffee beans and the espresso coffee beverage extracted at the optimum temperature is poured from the beverage supply pipe 16 into the cup C. Further, the hot water stored in the hot water tank 7 is heated by the exhaust heat released from the condenser 42 of the cooling unit 40, so that the power consumption can be reduced.
