Description

[0001] Vending machine for liquid drink [0002]

The present invention relates to a liquid drink supply apparatus, and more particularly, to a liquid drink supply apparatus configured to mix cold water or hot water with a selected one of various liquid liquid drink concentrates to clean the passageway for a predetermined period of time.

Generally, in many places, such as a restaurant or a company, there is a drink supply device called a so-called vending machine that provides coffee or tea.

These vending machines provide coins or a free drink or drink. Currently, the vast majority of vending machines provide coffee or tea by supplying cold or hot water to powdered raw materials for economic reasons. This is because it is economical, easy to configure, and easy to handle because it is possible to provide a large amount of the raw material at once.

However, since the vending machine for supplying the raw material of powder is to add cold and hot water to the raw material of powder to provide a drink, the taste thereof is limited. Especially, in the trend of drinking coffee beans mainly as in the present,

For this reason, vending machines that taste like coffee beans are required. A specialty store that sells coffee beans is equipped with expensive equipment, and since the coffee is extracted by changing the beans, the flavor is fresh and extracted immediately, so you can feel the aroma of the beans.

Similarly, a vending machine in which the process of grinding beans and applying pressure to extract beans are all provided automatically is inexpensive. However, since it is necessary to lower the pressure of water by using a pump to grind the beans, It takes about one minute, which is inadequate for use in a restaurant or the like, which is used by many people consecutively.

In addition, although the cleaning cycle of the powdered raw material vending machine can be set to be long, the coffee bean machine of the coffee bean has a problem that the cleaned cycle is short because the used coffee beans are cleaned and the contaminated part is cleaned.

In order to solve these problems, a liquid drink supply apparatus for providing liquid coffee has been developed. However, in the case of a liquid drink supply apparatus, a structural defect in which a material is hardened at a discharge unit that provides highly concentrated coffee or high viscosity syrup, There is a problem that the raw material of the liquid remains in the pipe and needs to be cleaned frequently or the pipe must be replaced periodically.

The upper part shows the state of the present feeding device 1 and the lower part has a button for inputting an order. The left side is arranged to order hot coffee and the right side to order cold coffee.

And the kind of the concentrated liquid is controlled to be supplied singly or as a mixture selectively according to the selected order.

3 to 7, a liquid drink supply apparatus 1 according to the present invention includes a concentrate pump 28, first water pumps 32 and 42, a two-way valve 31, a reservoir 20, (91), a circulation pump (100), and a circulation pipe (101).

The concentrated liquid pump 28 is connected to a plurality of concentrated liquids, respectively, and delivers the concentrated liquid to a discharge port.

The first water pumps 32 and 42 are connected to the cold / hot water tanks 30 and 40 to transfer water or air to the discharge port.

Way valve 31 is installed between the first water pump 31 and the cold water tank 30 so that the first water pump 32 pressurizes water or air.

The concentrated liquid pump 28 and the first water pump 32 are operated to supply the concentrated liquid and the water to the discharge port and then the two way valve 31 and the first water pump 32 operate to discharge air Thereby eliminating the residues.

A second water pump 33 is installed in a connection pipe connecting the two-way valve 31 and the first water pump 32, and an inlet of the second water pump 33 may be connected to a new cold water source.

The first water pump 32 and the two-way valve 31 may be installed in the cold water tank 30 and the hot water tank 40, respectively.

A solenoid valve 35 is provided between the first water pump 32 and the discharge port and a check valve 36 is provided between the solenoid valve 35 and the discharge port.

The reservoir (20) stores the plurality of concentrate packs (2).

The refrigerant pipe 91 extends through the cold water tank 30 and then passes through the storage 20 so that the refrigerant is evaporated to cool the storage 20.

The circulation pump 100 is connected to one side of the cold water tank 30 to circulate water in the cold water tank 30.

The circulation pipe 101 extends from the circulation pump 100 and is connected to the cold water tank 30 through a part of the storage 20.

6, the concentrated liquid is stored in a concentrated liquid pack 2, and three concentrate packs 2 are installed. The concentrate pack (2) is installed in the reservoir (20) to be supported by a support. The concentrate pack (2) has an inlet connected to a concentrate supply pipe (22) extending upward.

The concentrate supply pipe 22 extends upward and is connected to each of the concentrate pumps 28 fixed on the upper surface of the reservoir 20. Accordingly, when the concentrated liquid pump 28 operates, the concentrated liquid corresponding to the concentrate liquid is transported along the supply pipe 22.

The concentrated liquid conveyed by the concentrate pump 28 goes down through the branch pipe 23 extending into the storage tank 20 again. Thereafter, the mixture is passed through the mixing tube 24 and mixed with other materials in the mixing tube 25 in which the mixing screw 25a is embedded, and is then discharged into the cup through the discharge tube 26.

One or more pumps in the three concentrate pumps 28 are operated according to the order inputted from the control panel 14, and the concentrate is mixed and discharged.

As will be described later, the concentrate pack 2 is configured to maintain the temperature of the reservoir 20 at a low temperature, thereby extending the refreshing sensation, the effective period, and the flavor period.

3 to 5, the first water pump 32 is installed on the upper portion of the cold water tank 30 and pumps the water in the cold water tank 30. A second water pump 33 is connected to the side of the first water pump 32 and pumps the cold water of the cold water tank 30 together with the first water pump 32 normally.

The second water pump 33 may be connected to another water tank, for example, another constant water tank or a cold water tank. That is, a separate water source may be connected or the cold water of the cold water tank 30 may be pumped in cooperation with the first water pump 32.

Way valve 31 is installed between the cold water tank 30 and the first water pump 32. Under the control of the two-way valve 31, the first water pump 32 pumps the cold water or the air. Referring to FIG. 8, the role of the two-way valve 31 is well known. And the air or cold water in the cold water tank 30 is selected to be supplied according to the selection of the two-way valve 31. It is, of course, possible to perform cleaning by the role of the two-way valve 31.

The cold water or air is fed to the first water pump 32 by way of the supply pipe 34. A solenoid valve 35 is installed in the middle of the supply pipe 34 to control the supply of cold water or air. The supply pipe 34 is connected to the hot water supply pipe 44 by a connection pipe 50 so as to be connected in parallel with each other and the connection pipe 50 is branched into three branch pipes 51, ) To the concentrate branch 23, and is then transported along a conduit, such as a concentrate. Of course, before connecting to the concentrated liquid supply pipe 22, each branch pipe 51 is provided with a check valve 36 to prevent backflow.

It is needless to say that such a configuration can be similarly configured for the hot water side. Here, the pipeline is cleaned with cold / hot water to suit the cold and hot use. The two-way valve 31 is provided with a hot water outlet 46a for controlling the flow rate of warm water and air and a solenoid valve 46 equipped with an air vent 46b without using a two-way valve in the hot water tank. Hot water or air is supplied to the hot water pipe 41 according to the operation of the solenoid valve 46 (see FIG. 9).

The hot water side line will be described with reference to Figs. 3 to 5. Fig. The hot water is stored in the hot water tank 40. Since the hot water is supplied with hot water by installing a heater therein, it is a general configuration, so it is omitted. The hot water is connected to the first water pump 42 on the hot water side along the hot water pipe 41. Here, the two-way valve 31 is omitted. Accordingly, the first water pump 42 is directly connected to the hot water, and when pumping is started, only the hot water is unconditionally pumped. A second water pump 43 is provided on the hot water side to connect fresh hot water on the cold water side or to assist the first water pump 42 on the cold water side.

Hot water is fed to the first water pump 42 by way of the supply pipe 44. A solenoid valve 45 is installed in the middle of the supply pipe 44 to control the supply of hot water. The supply pipe 44 is connected to the cold water supply pipe 34 by a connection pipe 44 so as to be connected in parallel with each other. The next is the same as the cold water side explanation.

A water reservoir 70 is provided on the side of the cold water tank 30 and an overflow pipe 61 and a water receiver 60 are connected to the cold water tank 30. Supply pipes 81 and 82 controlled by a water supply solenoid valve 83 and a water supply and supply pump 84 are installed in the upper part of the cold water tank 30 to control the solenoid valve 83 And water is supplied to the water reservoir 70 through a water supply pump 84 at a place where there is no water purifier or water supply facility. This configuration is configured differently depending on the environment in which it is installed.

The water tank 70 serves to supply water to the cold water tank and the hot water tank respectively. The float sensor is attached to the cold water tank to check the water level. The water in the water tank 70 is pumped or natural pressure is adjusted Supply. The hot water tank is provided with a pipe connected to the hot water tank at the lower end of the water tank to supply water by natural dropping.

3 and 4, a compressor 90 supported by the frame 11 is provided in the lower portion of the inside of the case 10, and the compressor 90 compresses the refrigerant.

The refrigerant compressed by the compressor 90 passes through the coolant tank 30 and the inside of the storage tank 20 through the refrigerant pipe 91 and then is condensed in the condenser 92 and then supplied to the compressor 90 again. Circulate. The refrigerant compressed by the compressor (90) evaporates while passing through the refrigerant pipe (91). At this time, the refrigerant absorbs the surrounding heat, thereby performing the cooling function. The evaporated refrigerant is condensed and liquefied while staying in the condenser 92, and then supplied to the compressor 90 again.

This cooling cycle is very common. Here, however, there is a feature that the storage compartment 20 is provided so as to pass through the refrigerant pipe 91.

A groove 20a is formed in the rear surface of the storage tank 20 and the storage tank 20 is cooled by inserting the refrigerant pipe 91 into the groove 20a.

The cold water tank 30 is provided with the refrigerant pipe 91 extending through the inside thereof, so that the cold water temperature of the cold water tank 30 is lowered. That is, the temperature of the water around the refrigerant pipe 91 is lowered. However, since the compression capacity of the compressor 90 is improved and the temperature around the refrigerant pipe 91 is rapidly lowered, ice is formed around the refrigerant pipe 91, thereby causing a problem of drastically lowering the cooling efficiency. In order to solve such a problem, water around the coolant tank 91 inside the cold water tank 30 is circulated. That is, the circulation pump 100 is used to circulate water in the cold water tank 30 continuously to prevent the occurrence of freezing around the refrigerant pipe 91.

Here, one pipe is additionally connected to the structure in which the circulation pump 100, which is originally installed, is connected to the cold water tank 30, and is connected to the circulation pipe 101 through the circulation pipe 101, And is inserted into the groove 20b to be passed therethrough and extended again to be made up of the cold water tank 30. [ Accordingly, the cold water in the cold water tank 30 is circulated by the circulation pump 100 along the cold water tank 30 and the circulation pipe 101.

The circulation pump 100 and the circulation pipe 101 are used to refrigerate the storage 20 and circulate the water in the refrigeration tank 30 so that the water does not freeze down. (° C).

6 and 7, a plurality of concentrate packs 2 are installed in the reservoir 20 and are respectively connected to the concentrate pump 28 by a pipe 22, (25), and a discharge pipe (26) are also provided. A fan (27) is installed at the bottom to circulate air inside the storage compartment (20).

The operation of the device 1 will be described.

First, the user selects a beverage to be drunk by using the control panel 14 and inputs it.

When cold coffee is selected, the concentrate pump 28 operates so that the corresponding concentrate is extracted. The concentrate is transferred to the supply pipe 22 by a pumping action. Thereafter, the two-way valve 31 on the cold water side operates to extract the cold water, and at the same time, the first water pump 32 operates to pressurize the cold water to the supply pipe 34.

At this time, the cold water side solenoid valve 35 is of course open. The cold water continues to flow to the mixing tube 24 through the connecting tube 50 and the branch tube 51 and is mixed with the concentrated liquid in the mixing tube 25 so that the refrigerant is discharged through the discharge tube 26.

Thereafter, the two-way valve 31 is stopped and the air is sucked in. The first water pump 32 is continuously operated for a set time, and the solenoid valve 35 is also opened, After removal by pressure, the first water pump 32 stops operating, and the solenoid valve 35 is closed.

 Of course, since the concentrate pack 2 is stored in the storage 20, very cool coffee will be extracted.

On the other hand, when hot coffee is selected, the concentrated liquid pump 28 operates so that the corresponding concentrated liquid is extracted. The selected concentrate is transferred to the supply line 22 by a pumping action. Thereafter, the first water pump 42 on the hot water side operates to pressurize hot water to the supply pipe 44.

At this time, the hot water side solenoid valve 45 is of course open. Hot water continues to flow to the mixing pipe 24 through the connecting pipe 50 and the branch pipes 51 and 23 and is mixed with the concentrated liquid in the mixing pipe 25 to discharge the hot coffee through the discharge pipe 26.

Thereafter, the solenoid valve 46 of the hot water side hot water tank 40 opens to open the air vent 46b so that the air is sucked in. The first water pump 42 is continuously operated for a predetermined time, The first water pump 42 is stopped, and the solenoid valve 45 is closed.

Here, the two-way valve 31 is provided only on the cold water side to implement the remediation, but it is needless to say that a two-way valve may be installed on the hot water side.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the inventions. It will be apparent to those of ordinary skill in the art.
