  This application claims the benefit of Patent Application No. 2009-196949 filed in Japan on August 27, 2009, the contents of which are incorporated herein by reference.

  The present invention relates to a beverage server that supplies beverages contained in bottles.

  2. Description of the Related Art Conventionally, beverage servers that supply beverages such as water contained in bottles are known. By the way, when air that has not been sterilized enters into the bottle, it causes the propagation of various germs and the generation of mold.

  The beverage dispenser described in Patent Document 1 uses a bottle whose side wall portion is bent so that the inner volume of the bottle becomes smaller as the beverage flows out. Thereby, since air, germs in the air, etc. are not mixed in the beverage inside the bottle, there is an effect that the taste of the beverage does not change and it is hygienic.

  Moreover, in the drink dispenser described in patent documents 2-4, the drink in a tank is kept from touching air by keeping a tank in a full water state.

  However, the conventional water cooler for beverages such as Patent Document 1 has a problem that water cannot be taken out from the bottle. In other words, since the bottle has a force to resist deformation, when the beverage in the bottle is reduced and the weight of water is reduced, the weight of the beverage in the bottle balances the drag of the bottle and the beverage comes out. It will disappear.

  Moreover, the method of making the inside of a tank full like patent documents 2-4 is effective in preventing mixing of the germs etc. in air. However, in reality, it is difficult to completely eliminate air from the tank. For example, when the bottle is removed from the beverage server, air enters the tank. In addition, since air has a small bulk elastic modulus, air has a function as a buffer region against an instantaneous bottle volume change. This is especially true in the case of a deformable bottle. If there is no air in the tank, there is a risk of water leaking from the tank due to the impact on the bottle.

  In view of the above background, an object of the present invention is to provide a beverage server in which a beverage is prevented from remaining in a bottle as much as possible.

The beverage server of the present invention is a beverage server that supplies a beverage from a bottle that deforms according to a beverage spill, is provided below the bottle, stores the beverage spilled from the bottle, and is higher than the water level of the beverage to be stored A storage tank having an air port at a position, a check valve provided at the air port in order to prevent air from flowing into the storage tank, and a beverage in the storage tank at a predetermined water level. A float valve for closing the air port so that air does not flow out of the storage tank, and a cock for taking out the beverage from the storage tank.

The storage tank has an air port for extracting air when supplying a beverage. A check valve is provided at the air port to prevent air from entering from the outside. Thereby, when taking out the beverage in the storage tank from the cock, the beverage is sucked from the bottle by the weight of the beverage in the storage tank in addition to the weight of the beverage in the bottle. Therefore, even if the beverage in the bottle is low, it is sucked strongly, so that it is difficult for the beverage to remain in the bottle. Further, when the beverage in the tank reaches a predetermined water level, the total of the pressure in the storage tank and the force that the bottle 30 resists deformation is determined by the weight of the beverage in the bottle by closing the air port with the float valve. In balance, the flow of beverage from the bottle to the storage tank stops. Since air is contained in the storage tank, even when an impact is applied to the bottle, the air functions as a buffer and water does not leak from the tank.

  The beverage server of the present invention may include an air inflow prevention mechanism for preventing air from flowing from the storage tank to the bottle in the liquid supply pipe from the bottle to the storage tank.

  With this configuration, air does not flow into the bottle even when the pressure in the storage tank increases.

  In the beverage server of the present invention, the air inflow prevention mechanism is inserted into the beverage outlet of the bottle and extends in an L shape in the storage tank, and has a diameter larger than the diameter of the liquid supply tube. And a valve body that moves by the flow of a beverage that flows back through the liquid supply pipe and closes the flow path of the liquid supply pipe. When the pressure in the storage tank increases, the water level of the beverage stored in the eaves portion decreases, and the valve body is connected to the supply pipe by the reverse flow of the drink generated in the supply pipe. It is good also as a structure which obstruct | occludes a flow path.

  With this configuration, when the water surface of the buttock is pushed down due to an increase in the pressure in the storage tank, a reverse flow with a flow rate faster than the rate at which the water level of the buttock lowers is fed to the liquid supply pipe having a diameter smaller than the diameter of the buttock. The valve body moves and closes the flow path of the liquid supply pipe. Then, after the flow path of the liquid supply pipe is closed, the pressure in the storage tank is suppressed in the direction in which the valve body is closed, so that the flow path of the liquid supply pipe is reduced until the pressure in the storage tank decreases. Is blocked. Thereby, even if the pressure in the storage tank rises, air can be prevented from entering the bottle from the storage tank.

  The beverage server of the present invention is heated in the warm beverage storage tank that heats and stores the beverage supplied from the storage tank, the warm beverage cock that extracts the beverage from the warm beverage storage tank, and the warm beverage storage tank. And a conduit having a control valve for returning the beverage to the storage tank.

  By returning the heated beverage to the storage tank from the warm beverage storage tank storing the warm beverage in this manner, the beverage and air in the storage tank can be sterilized by heating.

  The beverage server of the present invention includes a pipe line extending from an upper part of the hot beverage storage tank to a position higher than the predetermined water level of the storage tank, and the pipe line generates steam generated in the hot beverage storage tank. Supply to the storage tank.

  With this configuration, even during normal operation, steam heated in the hot beverage storage tank is supplied to the storage tank, and heat sterilization is performed.

The beverage server of the present invention is a beverage server that supplies a beverage from a bottle that deforms according to a beverage spill, is provided below the bottle, stores the beverage spilled from the bottle, and is higher than the water level of the beverage to be stored A storage tank having an air port formed at a position, a warm beverage storage tank that heats and stores a beverage supplied from the storage tank, and an air port provided to prevent inflow of air into the storage tank A check valve , a float valve for closing the air port so that air does not flow out of the storage tank when the beverage in the storage tank reaches a predetermined water level, and from the bottle to the storage tank. An air inflow prevention mechanism for preventing inflow of air from the storage tank to the bottle and a beverage heated in the hot beverage storage tank are returned to the storage tank. A first conduit having a control valve and an upper portion of the warm beverage storage tank extending to a position higher than the predetermined water level of the reservoir tank, and generating steam in the warm beverage storage tank from the reservoir tank A second pipe for supplying the beverage, a cock for taking out the beverage from the storage tank, and a warm beverage cock for taking out the beverage from the hot beverage storage tank, wherein the air inflow prevention mechanism is provided at the beverage outlet of the bottle. A liquid supply pipe that is inserted and extends in an L shape in the storage tank, and a flange having a diameter larger than the diameter of the liquid supply pipe, the liquid supply pipe being connected to the vicinity of the bottom thereof And a valve body that moves by the flow of the beverage flowing backward through the liquid supply pipe and closes the flow path of the liquid supply pipe, and stores the pressure in the storage tank when the pressure in the storage tank increases. The water level of the brewed beverage drops and it With the valve body by the backflow of beverage generated in the liquid supply pipe to close the flow path of the liquid supply pipe.

  With this configuration, even if the beverage in the bottle is low, it is strongly sucked, so that it is difficult for the beverage to remain in the bottle, and air does not flow into the bottle even when the pressure in the storage tank increases. . By returning the heated beverage from the hot beverage storage tank to the storage tank, the beverage and air in the storage tank can be sterilized by heating. Even during normal operation, steam heated in the hot beverage storage tank is supplied to the storage tank, and heat sterilization of the air in the storage tank is performed.

  According to the present invention, when the beverage in the storage tank is taken out from the cock, air does not enter from the outside. Therefore, the beverage in the bottle is added to the weight of the beverage in the storage tank in addition to the weight of the beverage in the bottle. It will be sucked by this, and it becomes difficult for the beverage to remain in the bottle.

  Hereinafter, a beverage server according to an embodiment of the present invention will be described with reference to the drawings. Below, although the water server which supplies water as a drink is demonstrated as an example, the drink which the drink server of this invention supplies is not limited to water.

(First embodiment)
FIG. 1 is a diagram illustrating an appearance of a water server 1 according to the first embodiment. As for the water server 1 of this Embodiment, the water bottle 30 is set to the upper part. The water server 1 temporarily stores the water flowing out from the water bottle 30 in the storage tank of the water server 1, and takes out the water from the storage tank when the water supply cocks 14 and 15 are opened. The water server 1 has two water supply cocks 14 and 15. One water supply cock 14 supplies cold water, and the other water supply cock 15 supplies hot water.

  The bottle 30 is made of, for example, PET resin (polyethylene terephthalate resin). The PET resin is odorless at room temperature, and there is no fear that the odor will be transferred to the liquid filled inside. Further, the PET resin is relatively hard and can maintain its shape independently without being greatly deformed even when filled with water.

  A bellows 31 is formed on the side surface of the bottle 30, and the bottle 30 is crushed as water flows out of the bottle 30. FIG. 2A is a diagram showing a state in which about half of the water has flowed out of the bottle 30, and FIG. 2B is a diagram showing a state in which almost the entire amount of water has flowed out of the bottle 30. In FIG. 2A and FIG. 2B, in order to show the water W in the bottle 30, it is shown with sectional drawing. Thus, the volume of the bottle 30 decreases as the water W flows out of the bottle 30. Although the water W in the bottle 30 decreases, the air A remaining in the bottle 30 is constant. The air A is air that has been sterilized or sterilized when the bottle 30 is filled with water. As described above, the bottle 30 is deformed, so that the water W can be taken out without taking air into the bottle 30.

  FIG. 3 is a cross-sectional view of the water server 1 according to the present embodiment. The water server 1 includes a cold water storage tank (hereinafter referred to as “cold water tank”) 10 and a hot water storage tank (hereinafter referred to as “hot water tank”) 20. The cold water tank 10 and the bottle 30 are connected by a water supply pipe 11. The end of the water supply pipe 11 on the bottle 30 side stands up toward the top of the water server 1, and the end is inserted into the neck 32 of the bottle 30. The opposite end of the water supply pipe 11 is introduced into the cold water tank 10. The water supply pipe 11 has an air inflow prevention mechanism that prevents inflow of air from the cold water tank 10 to the bottle 30.

  FIG. 4A is a diagram showing a detailed configuration of the water supply pipe 11 provided with an air inflow prevention mechanism. The water supply pipe is bent in an L shape in the cold water tank 10. At the end of the water supply pipe 11 on the cold water tank 10 side, a flange 40 that temporarily stores the water flowing out of the bottle 30 is formed. The water supply pipe 11 supplies water from the bottom portion of the flange 40 and overflows from the flange 40 to supply water to the cold water tank 10. The flange 40 has a diameter larger than the diameter of the water supply pipe 11. For example, the diameter of the water supply pipe 11 can be 8 mm in diameter, and the diameter of the collar 40 can be about 15 to 20 mm or about 30 to 40 mm.

  A step 41 is formed in a portion of the water supply pipe 11 that extends downward from the bottle 30, and a part of the flow path is narrowed. A valve element 42 is provided below the step 41. As shown in FIG. 4B, the valve body 42 is pressed against the step 41, thereby closing the flow path of the water supply pipe 11 and preventing air from flowing from the cold water tank 10 into the bottle 30. FIG. 4A shows a state where the flow path is open.

  A plurality of fins 43 are provided around the valve body 42. In the state shown in FIG. 4A, water flows through the gaps between the fins 43 around the valve body 42. As shown to FIG. 4A, it has the stopper 44 for preventing the valve body 42 from falling down in the state where the flow path is open. The stopper 44 only needs to have a configuration that does not block the flow of water. For example, the stopper 44 may be a rod-shaped member or a configuration in which a plurality of rod-shaped members are crossed.

As shown in FIG. 3, an air port 12 is formed in the cold water tank 10. FIG. 5 is a cross-sectional view showing a detailed configuration of the air port 12 formed in the cold water tank 10. A check valve 50 is attached to the air port 12 so that air escapes from the inside of the cold water tank 10 to the outside, but air does not flow into the cold water tank 10 from the outside. Here, the configuration of the check valve 50 will be described.

The check valve 50 has a valve body 52 disposed outside a step 51 formed in the air port 12. When the valve body 52 is placed on the step 51, the air port 12 is closed. When the internal pressure of the cold water tank 10 increases, the pressure to flow out of the cold water tank 10 overcomes the weight and external pressure of the valve body 52, the valve body 52 is lifted upward, and the flow path of the air port 12 is opened. When the valve body 52 is lifted, the air passes through the gaps between the fins 53 provided around the valve body 52 and goes out. When there is no pressure difference between the chilled water tank 10 and the outside, or when the external pressure is higher, the flow path is closed while the valve body 52 remains on the step 51, so that the chilled water tank is externally provided. No air enters 10.

  A float valve 54 is attached to the air port 12. When the water level in the cold water tank 10 reaches a predetermined water level, the air port 12 is closed. Here, the structure of the float valve 54 will be described. The float valve 54 includes a valve body 55 disposed under a step 51 formed in the air port 12 and a float 57 that pushes up the valve body 55. In a state where the valve body 55 is away from the step 51, air passes through the gaps between the fins 56 around the valve body 55. When the float 57 is lifted by the rise of the water level in the cold water tank 10, the valve body 55 is pushed up accordingly. As a result, when the valve body 55 is pressed against the step 51, the air port 12 is closed, the air cannot be removed from the cold water tank 10, and the cold water tank 10 is sealed.

When the air port 12 is closed and the cold water tank 10 is in a sealed state, when the combined force of the internal pressure of the cold water tank 10 and the force against the deformation of the bottle 30 balances the weight of the water in the bottle 30, the bottle 30 From the water to the cold water tank 10 stops. When the water supply cock 14 connected to the cold water tank 10 is opened, the water in the cold water tank 10 flows out from the water supply cock 14. Since air does not enter the cold water tank 10 due to the action of the check valve 50 provided at the air port 12, water is supplied from the bottle 30 to the cold water tank 10 by the amount of water flowing out of the cold water tank 10. Is done. Thereby, the cold water tank 10 maintains a constant water level.

  With reference to FIG. 3 again, the configuration of the water server 1 will be described. The cold water tank 10 and the hot water tank 20 are connected by a water supply pipe 21. The inlet of the water supply pipe 21 on the cold water tank 10 side is provided not at the bottom of the cold water tank 10 but at the center of the disk 13 arranged at a predetermined height. Thus, the water is supplied to the hot water tank 20 only when the water is filled up to the height of the disk 13 in the cold water tank 10.

  A heater 22 is provided at the bottom of the hot water tank 20 to heat the water stored in the hot water tank 20. When the water supply cock 15 connected to the hot water tank 20 is opened, the hot water in the hot water tank 20 flows out from the water supply cock 15 through the water supply pipe 23. Although the water supply cock 15 is at a position higher than the hot water tank 20, it is at a position lower than the bottle 30 and the cold water tank 10, so when the water supply cock 15 is opened, the hot water naturally flows out due to its own weight. In addition, since the hot water outlet of the water supply pipe 23 is provided in the upper part of the hot water tank 20, hot water can be taken out from the part where the temperature of the hot water tank 20 is high.

  The water server 1 includes a water supply pipe 24 for supplying hot water in the hot water tank 20 to the cold water tank 10. An electromagnetic valve 25 for sucking up hot water from the hot water tank 20 to the cold water tank 10 is attached to the water supply pipe 24. By supplying hot water to the cold water tank 10 through the water supply pipe 24 and increasing the water temperature and air temperature in the cold water tank 10, the cold water tank 10 can be sterilized by heating. For example, the temperature of the hot water in the hot water tank 20 is 85 ° C to 90 ° C. By supplying this hot water to the cold water tank 10 and raising the water temperature in the cold water tank 10 to about 70 ° C., the cold water tank 10 can be sterilized.

  6-8 is a figure which shows a mode when water is supplied to the cold water tank 10 and the hot water tank 20 from the bottle 30. FIG. When the bottle 30 is set in the water server 1, the water in the bottle 30 flows out into the cold water tank 10 by its own weight as shown in FIG. At this time, as indicated by an arrow 16, the air in the cold water tank 10 escapes from the air port 12 as the water level of the cold water tank 10 rises.

  When the water level in the cold water tank 10 reaches the position of the disk 13, the water in the cold water tank 10 is supplied to the hot water tank 20 through the water supply pipe 21, as shown in FIG. At this time, the water level in the cold water tank 10 does not change. When the hot water tank 20 becomes full, the water level of the cold water tank 10 starts to rise further from the position of the disk 13. When the water level of the cold water tank 10 rises, air escapes from the air port 12 as in the case shown in FIG.

  When the water level of the cold water tank 10 rises and the float 57 is pushed up as shown in FIG. 8, the float valve 54 is closed and the air port 12 is closed, so that air does not escape from the cold water tank 10 to the outside. The combined force of the internal pressure of the air in the cold water tank 10 and the force with which the bottle 30 resists deformation balances the weight of the water remaining in the bottle 30, and the outflow of water from the bottle 30 to the cold water tank 10 stops. .

  The process which heat-sterilizes the cold water tank 10 is demonstrated. First, the water in the hot water tank 20 is heated by the heater 22. Here, heating is performed until the water temperature in the hot water tank 20 becomes 85 ° C. to 90 ° C., for example. Next, the solenoid valve 25 is actuated to suck the hot water in the hot water tank 20 into the cold water tank 10 and raise the temperature of the water in the cold water tank 10. Hot water is supplied until the water temperature in the cold water tank 10 reaches 70 ° C., for example. As the water temperature in the cold water tank 10 increases, the air in the cold water tank 10 is sterilized.

  During this heat sterilization treatment, the internal pressure of the cold water tank 10 increases, but in this embodiment, the air supply prevention mechanism is provided in the water supply pipe 11 that connects the cold water tank 10 and the bottle 30. Air in the tank 10 does not enter the bottle 30. That is, when the internal pressure of the cold water tank 10 is increased, as shown in FIG. 4B, the water stored in the flange 40 is pushed in by the air pressure, and the water level of the flange 40 is lowered. Since the diameter of the collar part 40 is larger than the diameter of the water supply pipe 11, when the water level of the collar part 40 falls, the water in the water supply pipe 11 flows backward with a certain amount of momentum. For example, when the diameter of the collar part 40 is twice the diameter of the water supply pipe 11, the flow velocity in the water supply pipe 11 is four times the speed at which the water level of the collar part 40 decreases. In addition, the diameter of the collar part 40 and the magnitude | size of the diameter of the water supply pipe 11 can be set to an appropriate value by design. The water flow generated in the flow path of the water supply pipe 11 pushes up the valve element 42 of the air inflow prevention mechanism, and the flow path of the water supply pipe 11 is closed. After the flow path of the water supply pipe 11 is closed, the valve body 42 is pushed up by the internal pressure of the cold water tank 10, so that the flow path of the water supply pipe 11 remains closed until the internal pressure of the cold water tank 10 decreases. Become.

Since the water server 1 of the present embodiment is provided with the check valve 50 for preventing the inflow of air at the air port 12 of the cold water tank 10, air does not enter the cold water tank 10 from the outside. Thereby, when taking out the water in the cold water tank 10 from the water supply cock 14, the water in the bottle 30 is sucked by the weight of the water in the cold water tank 10 in addition to the weight of the water in the bottle 30. It becomes difficult for water to remain in the bottle 30.

Moreover, since the water server 1 of this Embodiment has the float valve 54 which obstruct | occludes the air port 12 when the cold water tank 10 becomes a predetermined water level, the cold water tank 10 became the predetermined water level. Sometimes, the combined force of the internal pressure of the cold water tank 10 and the force with which the bottle 30 resists deformation balances the weight of the water remaining in the bottle 30, and the supply of water from the bottle 30 can be stopped.

  Moreover, since the water server 1 of this Embodiment has provided the air inflow prevention mechanism in the water supply pipe | tube 11 which connects the bottle 30 and the cold water tank 10, for example at the time of heat sterilization etc., the cold water tank 10 Even when the internal pressure increases, air does not flow back into the bottle 30.

  In the water server 1 according to the present embodiment, air exists between the water in the cold water tank 10 and the bottle 30. If the water in the cold water tank 10 and the bottle 30 can be circulated without the presence of air, the water in the bottle 30 is heated. This is not only inefficient, but the bottle 30 may be damaged by heat. Since the water server 1 of this Embodiment should just heat the water in the cold water tank 10 at the time of heat sterilization, it is efficient and there is no possibility that the bottle 30 may be damaged by heat.

(Second Embodiment)
FIG. 9 is a diagram illustrating a configuration of the water server 2 according to the second embodiment of this invention. The basic configuration of the water server 2 of the second embodiment is the same as that of the water server 1 of the first embodiment, but in addition to the configuration of the water server 1 of the first embodiment, a hot water tank The difference is that a steam supply pipe 58 extending from the upper part of 20 to the cold water tank 10 is provided. The steam supply pipe 58 supplies the steam generated in the hot water tank 20 to the cold water tank 10. Hereinafter, a configuration different from the first embodiment will be described.

  In FIG. 9, the water level 59 is the water level when the air port 12 is closed by the float valve 54 provided in the cold water tank 10. The steam supply pipe 58 is connected to the cold water tank 10 at a position higher than the water level 59 at this time. Further, the steam supply pipe 58 extends to a position higher than the ceiling surface 60 of the cold water tank 10. Thereby, even if the water level of the cold water tank 10 reaches the ceiling surface 60 in the cold water tank 10 for some reason, water does not flow from the cold water tank 10 into the hot water tank 20 via the steam supply pipe 58. .

  In the water server 2 according to the second embodiment, since the steam heated in the hot water tank 20 is supplied through the steam supply pipe 58 even during normal operation, the cold water tank 10 is sterilized by heating. . The steam supply pipe 58 also serves to release bubbles that tend to accumulate in the upper part of the hot water tank 20 to the cold water tank 10. If air bubbles accumulate in the hot water tank 20, when the water supply cock 15 is opened, the air bubbles are discharged prior to the hot water. Therefore, it may take time until the hot water comes out after the water supply cock 15 is opened. According to the present embodiment, it is possible to shorten the time from the opening of the water supply cock 15 to the start of the supply of hot water.

  The water server 1 of the present invention has been described in detail with reference to the embodiment, but the present invention is not limited to the above-described embodiment.

  In the above-described embodiment, the water server 1 having the cold water tank 10 and the hot water tank 20 is described as an example, but the present invention can also be applied to the water server 1 having only the cold water tank 10. .

  In the above-described embodiment, the example in which the valve body 42 constituting the air inflow prevention mechanism is provided in the portion of the water supply pipe 11 extending downward from the bottle 30 has been described, but the valve body 42 is horizontal to the L-shaped water supply pipe 11. You may provide in the part extended in.

  In the second embodiment described above, the water server 2 including both the water supply pipe 24 and the steam supply pipe 58 has been described. However, the water server of the present invention may include only the steam supply pipe 58. Further, the water server of the present invention may be configured not to include both the water supply pipe 24 and the steam supply pipe 58.

  As described above, according to the present invention, there is an effect that it is difficult for a beverage to remain in a bottle, and it is useful as a beverage server or the like that supplies a beverage contained in a bottle that is deformed as the beverage flows out.
