1 is a view for schematically explaining a first supply device 100 according to an embodiment of the present invention. However, the drawings are not expressed in a strict sense, and there may be components not shown in the drawings for convenience of description.

Referring to FIG. 1 , the first supply device 100 includes a cold water tank 10 and a hot water tank 12 . A separation plate 11 is mounted inside the cold water tank 10 , and layers having different temperatures are formed based on the separation plate 11 . The hot water tank 12 heats the cold water supplied from the cold water supply pipe 13 by a heating means such as a heater to form hot water. At this time, the cold water tank 10, the separating plate 11, the hot water tank 12, and the cold water supply pipe 13 can all be applied in a known manner, which is briefly expressed here. Accordingly, the cold water tank 10, the separation plate 11, the hot water tank 12 and the cold water supply pipe 13 have known elements for smoothly performing and expanding the functions of the present invention within the scope of the present invention, e.g. For example, cooling means may be added. The cold water and hot water are used to provide a plurality of beverages in the first supply device 100 .

The cold water tank 10 is connected to the cold water outlet pipe 20 to supply cold water to the multiple outlet pipe 23, and the hot water tank 12 is a hot water outlet pipe 21 to supply hot water to the multiple outlet pipe 23. is connected with The cold water and hot water supplied from the cold water and hot water outlet pipes 20 and 21 are introduced into the multiple discharge pipe 23 through the collecting pipe 22 . The cold water outlet pipe 20 is equipped with a cold water valve 20a, and the hot water outlet pipe 21 is equipped with a hot water valve 21a. The cold water and hot water valves 20a and 21a are preferably solenoid valves. When the cold water and hot water valves 20a and 21a are opened, cold water and hot water are supplied to the multiple discharge pipe 23, and when closed, the cold water and hot water supply is stopped. Diameters of the cold water and hot water outlet pipes 20 and 21 may be determined in consideration of the amount of beverage discharged, and the like.

Any one or all of the cold water and hot water valves 20a and 21a is a three way valve. Specifically, the cold water valve 20a is a three-way valve and the hot water valve 21a is a first connection structure that is a two-way valve, or the cold water valve 20a is a two-way valve and the hot water valve 21a is The second connection structure that is a three-way valve, or the cold water and hot water valves 20a and 21a may all have a third connection structure that is a three-way valve. In the drawing, the third connection structure in which the cold water and hot water valves 20a and 21a is a three-way valve is expressed as an example. The three-way valve is connected to the first air supply pipe (30). The first air supply pipe 30 includes a first branch pipe 30a connected to the cold water valve 20a and a second branch pipe 30b connected to the hot water valve 21a, and first and second branch pipes ( 30a and 30b are combined to form the first main body 30c. At this time, the cold water tank 10 is equipped with a filter 31 that prevents the contaminants contained in the introduced air from entering.

In the first connection structure, the cold water valve 20a, which is a three-way valve, is connected to the cold water outlet pipe 20 and the first branch pipe 30a, and the hot water valve 21a, which is a two-way valve, is a hot water outlet pipe 21. is connected to In the second connection structure, the cold water valve 20a, which is a two-way valve, is connected to the cold water outlet pipe 20, and the hot water valve 21a, which is a three-way valve, is connected to the hot water outlet pipe 21 and the second branch pipe 30b. is connected to In the third connection structure, the cold water valve 20a, which is a three-way valve, is connected to the cold water outlet pipe 20 and the first branch pipe 30a, and the hot water valve 21a, which is a three-way valve, is a hot water outlet pipe 21. and the second branch pipe 30b. The connection structure may be determined in consideration of the use, structure, size, and the like for which the first supply device 100 is used.

The collecting pipe 22 is a pipe through which cold water and hot water flowing out from the cold water and hot water outlet pipes 20 and 21 pass. The cold water and hot water passing through the collecting pipe 22 flow in one direction (+x direction). When the cold water and the hot water flow in one direction (+x direction), it is possible to more efficiently implement the quantity dispensed water of a beverage and the distribution of a plurality of beverages. If there is no collecting pipe 22 , the cold water and hot water from the cold water and hot water discharge pipes 20 and 21 are directly fed into the multiple discharge pipe 23 . When the cold water and hot water are directly introduced into the multiple discharge pipe 23, the cold water and hot water flow in both directions (+x and -x directions). When the cold water and hot water flow in both directions (+x and -x directions), it is difficult to dispense a fixed amount and distribution of a plurality of beverages may be made inefficiently.

When the cold water and hot water passing through the collecting pipe 22 flow in one direction (+x direction), the amount of accumulated residue is reduced compared to the conventional method flowing in both directions (+x and -x directions). As the amount of residue is reduced, the time it takes to remove the residue is reduced. Since the embodiment of the present invention removes the residue immediately after the beverage is discharged, it is possible to significantly reduce the reproduction of bacteria as the time for which the residue is removed is reduced. Accordingly, the collecting pipe 22 is relevant for the purpose of the present invention to remove residues.

Multiple discharge pipe 23 is provided with discharge pipes (23a, 23b, 23c, 23d) for discharging a plurality of beverages. Here, four discharge pipes 23a, 23b, 23c, and 23d are presented, but two or more discharge pipes are possible. In this way, a combination of a plurality of discharge pipes is called a multiple discharge pipe (23). A plurality of beverages such as tea, beverage, cold water, hot water, and mixed water of cold water and hot water may be discharged to each of the four discharge pipes 23a, 23b, 23c, and 23d. An on/off valve 24 is attached to the multiple discharge pipe 23 . The on-off valve 24 is the on-off valves 24a, 24b, 24c, 24d attached to each of the discharge pipes 23a, 23b, 23c, and 23d. When the on-off valves (24a, 24b, 24c, 24d) are opened and closed, the discharge of a plurality of beverages from the discharge pipes (23a, 23b, 23c, 23d) is controlled.

The first supply device 100 forms a cold water flow path (a) and a hot water flow path (b), and provides any one of the first air flow path (c) or the second air flow path (d) to the first air supply pipe 30 . Alternatively, both the first and second air passages c and d may be formed. The first air flow path (c) is made when the valve for cold water (20a) is a three-way valve, and the second air flow path (d) is made when the valve for hot water (21a) is a three-way valve. Specifically, the first and second air passages (c, d) are at least one of a three-way valve for cold water (20a) or a hot water valve (21a) in a state in which the multiple discharge pipe (23) for discharging beverages is opened. It is formed when at least one of the first branch pipe 30a or the second branch pipe 30b is opened using In this case, the air introduced into the cold water tank 10 through the filter 31 is supplied through the first and second air passages c and d.

In the process in which the residue is removed, the pressure difference between the internal pressure of the collecting pipe 22 , the multiple discharge pipe 23 , and the first air supply pipe 30 and the pressure difference in the cold water tank 10 is utilized. When the beverage is discharged and exits, the pressure inside the collecting pipe 22, the multiple discharge pipe 23 and the first air supply pipe 30 becomes a vacuum state lower than atmospheric pressure. However, when at least one of the first branch pipe 30a or the second branch pipe 30b is opened in the state in which the multiple discharge pipe 23 through which the beverage is discharged is opened, the collecting pipe 22, the multiple discharge pipe 23 and the first class The inside of the engine 30 is in an air supply state in which air is supplied from the cold water tank 10 . After discharging the beverage and switching to the vacuum state, the air supplied from the cold water tank 10 is introduced into the collecting pipe 22 , the multiple discharge pipe 23 , and the first air supply pipe 30 . That is, the air supplied from the cold water tank 10 is introduced in the direction to fill the portion from which the beverage has escaped, as in the siphon principle, and the collecting pipe 22, the multiple discharge pipe 23 and the first air supply pipe 30 ) is filled with air in the cold water tank (10).

When the inside of the collecting pipe 22 , the multiple discharge pipe 23 , and the first air supply pipe 30 are converted to the air supply state, the residue falls by gravity and is discharged to the multiple discharge pipe 23 . When the removal of the residue is completed, the on/off valve 24b is closed to block the inflow of external air. The residue remains in the collecting pipe 22 and the multiple discharge pipe 23 due to the structure, surface tension, etc. of the first supply device 100 . If the remaining residue is maintained as it is, the residue becomes a place for bacteria to grow, and the impurities increase the probability of causing failure of parts such as an on/off valve. The embodiment of the present invention removes the residue, thereby preventing the propagation of various bacteria and blocking the inflow of contaminants such as impurities.

On the other hand, the process of discharging the beverage by the multiple discharge pipe 23 can be applied to a known method. That is, the opening/closing of the cold water and hot water valves 20a and 21a and the control of the opening/closing valves 24a, 24b, 24c, 24d may be operated in a known manner. However, the opening/closing valve (eg, 24c) for discharging cold water or hot water or a mixture thereof among the beverages is more than the opening/closing valve (eg, 24a, 24b, 24d) for discharging other beverages such as tea of the first supply device 100 It may be located lower than the bottom by the height difference (H). When the on/off valve 24c for discharging cold or hot water or a mixture thereof is located low in the vicinity, the residue is easily removed. At this time, the opening/closing valve 24c is present at a lower position than the conduit of the multiple discharge pipe. This is because a flow path is formed in which cold water, hot water, or a mixture thereof flows to the on/off valve 24c of a low position.

In some cases, the opening/closing valve (eg, 24c) for discharging the cold water or hot water or a mixture thereof has a height difference (H) with respect to the opening/closing valve (eg, 24a, 24b, 24d) for discharging other beverages as described above. It can be set to the opposite position. Specifically, because the on-off valve 24c is positioned higher than the other on-off valves (eg, 24a, 24b, 24d), before the residue reaches the other on-off valves (eg, 24a, 24b, 24d). The residue can be removed. That is, the opening/closing valve for discharging the cold water or hot water or a mixture thereof according to an embodiment of the present invention may have a height difference (H) with respect to the opening/closing valve discharging other beverages. Nevertheless, it is better that the on/off valve 24c is as low as the height difference H.

Hereinafter, a process in which the residue is discharged will be described in detail by taking the case of discharging the beverage together with hot and cold water through the discharge pipe 23b. According to the first connection structure, the cold water valve (20a), the hot water valve (21a) and the on/off valve (24b) are opened to discharge the hot water and the cold water to discharge the beverage together with the hot water and the cold water through the discharge pipe (23b). do. In a state in which the discharge is completed, the first branch pipe 30a is opened using the cold water valve 20a while maintaining the opening of the on/off valve 24b. In this case, the collecting pipe 22 , the multiple discharge pipe 23 , and the first air supply pipe 30 are in an air supply state supplied with air from the cold water tank 10 . At this time, since the first branch pipe 30a, the second branch pipe 30b, and the first pipe 30c communicate with each other, the entire first air supply pipe 30 is switched to the air supply state. When switched to the supply air state, the residue falls by gravity and is discharged to the discharge pipe 23b.

The air outside the cold water tank 10 flows into the cold water tank 10 through the filter 31 . Since contaminants such as various bacteria and impurities contained in the air introduced from the outside are removed by the filter 31 , purified air is introduced into the cold water tank 10 . Accordingly, the cold water tank 10 of the first supply device 100 is hygienic by blocking the inflow of various bacteria and impurities. The filter 31 purifies only the external air introduced in the process of removing the residue. The filter 31 may employ any known method, and a detailed description thereof will be omitted. The location of the filter 31 is not necessarily limited, and may be disposed at an appropriate location of the cold water tank 10 in consideration of structural characteristics.

Residue removal in the second and third connection structures may be performed in the same manner as in the first connection structure. The second connection structure is a three-way valve for hot water valve (21a) is utilized, the third connection structure is a three-way valve for cold water and hot water valve (20a, 21a) is utilized. In other words, the removal of the residue according to the embodiment of the present invention may be made in accordance with the connection structure determined in consideration of the use, structure, etc. used in the first supply device 100 .

Meanwhile, in order to more effectively remove the residue, the vibrator 25 may be mounted at any position of the collecting pipe 22 or the multiple discharge pipe 23 . It is preferable that the vibrator 25 operates only in the process of removing the residue. The vibrator 25 is an element that induces vibration, such as a piezoelectric element. When the vibration is generated by the vibrator 25, the removal of the residue can be implemented quickly. All vibration modes may be applied to the vibrator 25, including a monopole mode, a dipole mode, a multipole mode such as a quadrupole mode, or a combination of these modes. For example, the dipole mode is driven by the two vibrators 25 attached to the outer wall of the conduit as shown in the figure, and is driven with a 180 degree phase difference. The quadrupole mode is driven by attaching the oscillators 25 shifted by 90 degrees with respect to each other at right angles, and a phase difference of 90 degrees occurs. In this way, if the position of the vibrator 25 attached to any position of the collecting pipe 22 or the multiple discharge pipe 23 is changed, the residue can be removed more quickly by driving in different modes.

2 is a view for schematically explaining the second supply device 200 according to an embodiment of the present invention. At this time, the second supply device 200 is the same as the first supply device 100 except for the second supply pipe (32). Accordingly, detailed descriptions of overlapping parts will be omitted.

According to FIG. 2, the second air supply pipe 32 includes first and second conduits between the cold water valve 20a and the cold water tank 10, and between the hot water valve 21a and the cold water tank 10, respectively. 32a, 32b). Unlike the first and second branch pipes 30a and 30b of the first air supply pipe 30 , the first and second conduits 32a and 32b do not have a branched structure. The second air supply pipe 32, like the first air supply pipe 30, maintains the air supply state in the process of removing the residue. The second air supply pipe 32 may be selected in consideration of the purpose, structure, etc. in which the second supply device 200 is used.

3 is a view for schematically explaining the third supply device 300 according to an embodiment of the present invention. At this time, the third supply device 300 is the same as the first supply device 100 except for the third supply pipe (33). Accordingly, detailed descriptions of overlapping parts will be omitted.

According to Figure 3, the third air supply pipe 33 is composed of a second main pipe (33a), a third branch pipe (33b) and a fourth branch pipe (33c). The third air pipe 33 is different from the first air supply pipe 30 in that the second main pipe 33a has a different point where the third and fourth branch pipes 33b and 33c meet. Specifically, the meeting point of the third air supply pipe 33 is relatively close to the cold water and hot water valves (20a, 21a). That is, the first air supply pipe 30 meets at a relatively distant point. The third air supply pipe 33, like the first air supply pipe 30, maintains the air supply state in the process of removing the residue. The third air supply pipe 33 may be selected in consideration of the purpose, structure, etc. in which the third supply device 300 is used.

As mentioned above, the present invention has been described in detail with reference to preferred embodiments, but the present invention is not limited to the above embodiments, and various modifications may be made by those skilled in the art within the scope of the technical spirit of the present invention. It is possible. Although the first to third beverage supply devices have been presented according to the structure of the air supply pipe, the structure of the air supply pipe may be variously modified within the scope of the present invention, and thus the structure of the supply device may vary accordingly.
