Description

  The present invention relates to a beverage server that cools and heats beverages such as drinking water, stores them, and dispenses these beverages. More specifically, the present invention relates to breeding of bacteria in beverage containers and beverage passages and in beverage containers. The present invention relates to a beverage server that can efficiently prevent bacteria and the like from entering the beverage.

  Beverage servers that can cool and cool drinking water, such as mineral water, and those heated to warm water are known. These cold water and hot water are normally stored in a cold water tank and a hot water tank in the beverage server. In this case, since the temperature of the hot water is high (for example, about 80 ° C.), the bacteria do not propagate, but relatively few bacteria are present in the beverage container, the cold water tank, and the pipe connected to the cold water tank. The environment will be easy to breed.

  Therefore, a technique as described in Patent Document 1 below is known. Patent Document 1 describes a drinking water dispenser in which a sterilizer using an ultraviolet lamp is disposed immediately before a cold water extraction valve of a cold water supply unit to sterilize cold water to be supplied. Cold water is supplied from a water bottle to a cold water tank, a sterilizer, and a cold water extraction valve. And warm water is supplied from a water bottle to a cold water tank, a warm water tank, and a warm water extraction valve.

In order to prevent the growth of bacteria and the like, it is preferable to use a BIB (bag in box) type container. BIB is a paper container in which a bag-like container made of a flexible resin is arranged. In a BIB container, a beverage that has been sufficiently sterilized and sterilized in a factory is filled in the BIB container, and the inside is kept in a sealed state and transported to a final consumption place. For this reason, bacteria etc. do not penetrate | invade into the drink in a BIB container until it reaches the final consumption place. Beverage servers that use beverages such as mineral water filled in such BIB containers are also widely used.
JP 2000-085892 A

  As described above, the conventional beverage server has relatively few problems on the hot water side, but there is a problem that bacteria are likely to be generated on the cold water side tank and supply path, and in particular, the cold water side tank and supply path. It was necessary to frequently perform sterilization treatment. For this reason, time and cost are required for maintenance, and the running cost of the beverage server is increased. Moreover, if maintenance is neglected, there is a possibility that a drink that is not suitable for drinking may be poured out.

  Even in the technique of Patent Document 1, if the irradiation time of ultraviolet rays is short, the sterilization treatment may not be sufficiently performed. In addition, since the range where the sterilization effect reaches is limited to the range where ultraviolet rays reach, there is a problem that efficient sterilization treatment is difficult. In addition, since cold water is stored inside the cold water tank and there is a portion where the cold water stays for a long time, there is a problem in that bacterial growth easily proceeds in such a stay portion. Furthermore, it was necessary to add a sterilizer, which led to an increase in the cost of the beverage server.

  In addition, even in a beverage server using a BIB type beverage container as described above, there is a possibility that bacteria or the like may enter the beverage container from the base when the beverage container is replaced. In a beverage server that stores beverage containers at room temperature, once bacteria or the like enter the inside of the beverage container, the growth of bacteria or the like proceeds in a relatively short period of time, which is a major sanitary problem. .

  Then, an object of this invention is to provide the drink server which can prevent efficiently that bacteria etc. penetrate | invade into the drink in a container also at the time of replacement | exchange operation | work of a drink container.

  In order to achieve the above object, the beverage server of the present invention is a beverage server for heating and cooling and pouring a beverage supplied from a beverage container arranged so that the cap portion is at the bottom, A high-temperature tank for storing the beverage supplied from the beverage container in a heated state, a heater installed in the high-temperature tank, a high-temperature beverage dispensing cock for dispensing the beverage in the high-temperature tank, A low-temperature tank for storing the beverage supplied from the beverage container in a cooled state, a cooler installed in the low-temperature tank, a low-temperature beverage pouring cock for pouring the beverage in the low-temperature tank, and the base A low-temperature beverage outflow passage that is connected to a section and branches the beverage that has flowed out from the beverage container to the low-temperature tank side and flows out, and the beverage that has flowed out from the beverage container is branched and flowed out to the high-temperature tank side A branch member provided with a high temperature beverage outflow passage, a low temperature beverage supply pipe connecting the low temperature beverage outflow passage of the branch member and the low temperature tank, the high temperature beverage outflow passage of the branch member, and the A high-temperature beverage supply pipe connected to a high-temperature tank, a sterilization pipe connected to the high-temperature tank and circulating a high-temperature fluid for sterilization to the low-temperature beverage supply pipe, and connected to the sterilization pipe for sterilization A circulating pump for circulating the high-temperature fluid, and an on-off valve disposed in the sterilization pipe.

  In the beverage server, it is preferable that the high temperature fluid for sterilization flows into the low temperature beverage supply pipe from a vicinity of a connection portion between the low temperature beverage supply pipe and the low temperature tank.

  In the above beverage server, the beverage server has a cold beverage dispensing pipe connecting the cold tank and the cold beverage dispensing cock, and the high temperature fluid for sterilization heated the cold beverage dispensing pipe. Later, it can be made to flow into the cold beverage supply pipe.

  In the above beverage server, the high temperature fluid for sterilization can be caused to flow into the low temperature beverage supply pipe after flowing through the inside of the low temperature beverage dispensing pipe.

  In the beverage server, a pipe heater that heats a low-temperature beverage dispensing pipe that connects the low-temperature tank and the low-temperature beverage dispensing cock can be provided.

  In the beverage server, the base part includes a beverage opening / closing valve for opening / closing a beverage outflow from the base part, the beverage opening / closing valve is closed, and the circulation pump and It is preferable that the on-off valve is controlled to circulate the sterilizing high-temperature fluid to heat and sterilize the vicinity of the branch member and the base part.

  Since this invention is comprised as mentioned above, there exist the following effects.

  Since a sterilizing hot water circulation system is provided for sterilizing the vicinity of the branch member connected to the base of the beverage container, the sterilization inside the pipe and the vicinity of the branch member can be easily performed when replacing the beverage container. In the replacement operation, there is no possibility that bacteria or the like enter the new beverage container. Further, this sterilization treatment can be easily performed by anyone and can be completed in a short time. Furthermore, the cost of the beverage server can be reduced. Further, since the hot water for sterilization is circulated only to the necessary portions, it does not consume extra energy for sterilization, contributing to energy saving. Furthermore, since the cold water in a low temperature tank is not heat-sterilized, the flavor of natural water is not impaired.

  Since the high temperature fluid for sterilization is allowed to flow into the low temperature beverage supply pipe from the vicinity of the connection portion between the low temperature beverage supply pipe and the low temperature tank, the inside of the low temperature beverage supply pipe is simultaneously sterilized near the branch member. Sterilization can be performed, and sterilization can be performed efficiently.

  In the case where the high temperature fluid for sterilization is made to flow into the low temperature beverage supply pipe after heating the low temperature beverage supply pipe, in addition to the supply pipe for low temperature beverage in the vicinity of the branch member, The sterilization treatment can be performed at the same time, and the sterilization treatment can be performed efficiently.

  In the case where high temperature fluid for sterilization is allowed to flow into the low temperature beverage supply pipe after flowing through the inside of the low temperature beverage extraction pipe, in addition to the branch member, the low temperature beverage supply pipe, The pipes can be sterilized at the same time, and the sterilization can be efficiently performed. Furthermore, the sterilization treatment inside the low temperature beverage dispensing pipe is sufficiently and reliably performed.

  With a pipe heater that heats the low temperature beverage dispensing pipe, in addition to the branch member vicinity, the low temperature beverage supply pipe, the low temperature beverage dispensing pipe can be sterilized simultaneously and efficiently. Sterilization can be performed. Moreover, the piping of the hot water circulation system for sterilization can be simplified.

  Embodiments of the present invention will be described with reference to the drawings. Here, as a drink, drink water, such as mineral water, will be described as an example. FIG. 1 is a schematic diagram showing the overall configuration of the beverage server 1 of the present invention. A beverage container 10 is arranged on the top of the beverage server 1. The beverage container 10 is preferably a BIB (bag in box) type container as shown. BIB is one in which a bag-like container 12 made of a flexible resin is placed in a paper outer box. It is also possible to use a beverage container 10 other than a BIB container (for example, a synthetic resin bottle or the like).

  The base part 11 of the beverage container 10 is arranged in the lower part of the beverage container 10. The base part 11 and the bag-like container 12 are bonded and fixed in a sealed state. Beverage that has been sufficiently sterilized and sterilized in the factory is filled into the bag-like container 12, and the inside is kept sealed and transported to the final consumption place. For this reason, bacteria or the like do not enter the beverage in the BIB container until the final consumption place is reached.

  FIG. 2 is an enlarged cross-sectional view showing the configuration of the base 11 and the branch member 4 of the beverage container 10. The base part 11 is provided with a beverage opening / closing valve 13. By turning the beverage opening / closing valve 13 so that the communication hole 131 provided in the beverage opening / closing valve 13 is in the axial direction of the cap portion 11, the beverage is allowed to flow out of the beverage container 10. As shown in the figure, when the communication hole 131 is in a direction perpendicular to the axial direction of the base part 11, the beverage opening / closing valve 13 is in a closed state, and the beverage outflow is blocked. The beverage opening / closing valve 13 can be rotated by an operation lever 14 to perform an opening / closing operation.

  A connecting portion 41 of the branching member 4 is connected to the distal end portion of the base portion 11 in a liquid-tight state. The branch member 4 is entirely made of a metal material having good heat conduction. The outflow side of the branching member 4 branches into a cold water outflow passage 42 and a hot water outflow passage 43. One end of a cold water supply pipe 51 is connected to the cold water outlet 42. The other end of the cold water supply pipe 51 is connected to the low temperature tank 5. One end of a hot water supply pipe 61 is connected to the hot water outflow passage 43. The other end of the hot water supply pipe 61 is connected to the high temperature tank 6.

  Again, a description will be given with reference to FIG. When the beverage opening / closing valve 13 provided in the base part 11 of the beverage container 10 is opened, the drinking water in the beverage container 10 is cooled at a low temperature from the cold water outflow passage 42 and the hot water outflow passage 43 provided in the branch member 4 respectively. It is supplied to the tank 5 and the high temperature tank 6. The low temperature tank 5 is for storing drinking water (cold water) that has been cooled to an appropriate temperature. The high temperature tank 6 is for storing drinking water (hot water) heated to a high temperature.

  The low-temperature tank 5 is provided with a cooler 54, and the drinking water in the low-temperature tank 5 is cooled to an appropriate temperature (for example, 10 ° C. or less) as cold water by a cooling cycle including the compressor 7, the radiator 8 and the cooler 54. The temperature is maintained. A cold water cock 53 is connected to the upper portion of the low temperature tank 5 via a cold water pipe 52.

  When the lever of the cold water cock 53 is operated and opened, low-temperature cold water is poured out from the cold water cock 53. When cold water is poured out from the cold water cock 53, the same amount of drinking water is introduced from the beverage container 10 into the low temperature tank 5. Thus, the inside of the low temperature tank 5 is always full. A drain valve 55 and a drain pipe 56 are provided to completely discharge the drinking water in the low temperature tank 5 when not in use.

  The high temperature tank 6 is provided with a heater 64, and the drinking water in the high temperature tank 6 is heated by the heater 64 and is kept at a substantially constant high temperature (for example, 80 to 85 ° C.). For this reason, the drinking water in the high temperature tank 6 is completely sterilized and in a sterile state.

  A hot water cock 63 is connected to the upper portion of the high temperature tank 6 via a hot water pipe 62. When the lever of the hot water cock 63 is operated to open the hot water cock 63, hot hot water is poured out from the hot water cock 63. When hot water is poured out from the hot water cock 63, the same amount of drinking water is introduced from the beverage container 10 into the high temperature tank 6. Thus, the inside of the high temperature tank 6 is always full. A drain valve 69 and a drain pipe 70 are provided to completely discharge the drinking water in the high temperature tank 6 when not in use.

  One end of a sterilization pipe 65 is connected to the lower part of the high-temperature tank 6. The other end of the sterilization pipe 65 is connected to a hot water circulation pump 66, and one end of a sterilization pipe 67 is connected to the discharge side of the hot water circulation pump 66. The other end of the sterilization pipe 67 is connected to the cold water supply pipe 51, and the connection position is in the vicinity of the connection portion between the cold water supply pipe 51 and the low temperature tank 5 (near the lower end of the cold water supply pipe 51). . In addition, an electromagnetic on-off valve 68 is disposed in the middle of the sterilization pipe 67.

  These hot water circulation systems for sterilization are operated when the beverage container 10 is replaced (or when the first beverage container is disposed). That is, a new beverage container 10 is arranged, the branch member 4 is connected to the base portion 11, and the sterilization process is started while the beverage opening / closing valve 13 is kept closed. This is started, for example, by pressing a “start sterilization process at replacement” push button. When the sterilization process is started, the electromagnetic on-off valve 68 is opened, and the hot water circulation pump 66 is driven to supply hot hot water in the high temperature tank 6 to the lower end side of the cold water supply pipe 51.

  Hot hot water flows from the lower end of the cold water supply pipe 51 through the cold water supply pipe 51 to the branch member 4 side. Since the cold water cock 53 is closed and the low temperature tank 5 is full, hot water does not flow into the low temperature tank 5 side. The hot water is heated and sterilized inside the cold water supply pipe 51 and the branch member 4, and then returned to the high temperature tank 6 through the hot water outlet passage 43 and the hot water supply pipe 61. The hot water outlet 43 and the hot water supply pipe 61 are also sterilized by heating. Further, since the branch member 4 is made of a metal material having good heat conduction, the whole is heated to a high temperature and sufficiently sterilized. At this time, the tip of the base 11 is also sterilized by heating with hot water.

  The circulation of the hot water for sterilization is maintained for a time when the sterilization is sufficiently performed. For example, if the temperature of the hot water is 80 ° C. or higher, a circulation time of about 20 seconds to 1 minute is sufficient. The sterilizing hot water is circulated for a predetermined time by a timer or the like, and then the hot water circulation pump 66 is stopped and the electromagnetic on-off valve 68 is closed to automatically stop the hot water circulation. During normal use other than during sterilization, the electromagnetic on-off valve 68 is always closed.

  When the sterilization process is completed, the beverage opening / closing valve 13 is opened, and the drinking water in the beverage container 10 is supplied to the low temperature tank 5 and the high temperature tank 6. Even when the beverage opening / closing valve 13 is in the open state, the branching member 4 and the tip of the base portion 11 are already sufficiently heat-sterilized, so that there is no possibility that bacteria or the like will enter the beverage container 10. As described above, the sterilization process can be executed by a simple operation such as pressing a push button when the beverage container 10 is replaced. Thereby, the penetration | invasion of bacteria etc. in the drink container at the time of replacement | exchange operation | work can be prevented.

  Although not shown in FIG. 1, it is preferable to cover the outer periphery of the low temperature tank 5, the cold water pipe 52, the high temperature tank 6, and the hot water pipe 62 with a heat insulating material or the like. Thereby, power consumption for cooling and heating can be reduced, and the cold water and the hot water can be poured out from the cold water cock 53 and the hot water cock 63 while maintaining the appropriate temperature.

  The compressor 7, the heater 64, the hot water circulation pump 66, and the electromagnetic on-off valve 68 are driven and controlled by a drive control unit (not shown). The drive control unit drives and controls the heater 64 to keep the drinking water in the high temperature tank 6 at a predetermined high temperature (for example, 80 to 85 ° C.) and also drives and controls the compressor 7 to drink the drinking water in the low temperature tank 5. Is cooled and kept at a predetermined appropriate temperature (for example, 10 ° C. or lower). The drive control unit drives and controls the hot water circulation pump 66 and the electromagnetic on-off valve 68 to execute the sterilization process as described above.

  FIG. 3 is a diagram showing a first modification of the beverage server of the present invention. In this modification, the path of hot water supplied from the sterilization pipe 67 to the cold water supply pipe 51 is different from that in FIG. In addition, the same code | symbol is attached | subjected to the member common with the drink server 1 of FIG. In the first modification, the sterilizing hot water discharged from the hot water circulation pump 66 first flows from the sterilization pipe 67 into the end of the cold water pipe 52 on the cold water cock 53 side, and the inside of the cold water pipe 52 And flows into the vicinity of the lower end of the cold water supply pipe 51.

  These hot water circulation systems for sterilization are provided with electromagnetic on-off valves 68, 57, and 58. During normal use, the electromagnetic on-off valves 68, 57, and 58 are in the state of the electromagnetic on-off valve 68: closed, the electromagnetic on-off valve 57: closed, and the electromagnetic on-off valve 58: open, respectively. At this time, when the cold water cock 53 is opened, the cold water cooled in the low temperature tank 5 is poured out from the cold water cock 53. Then, the same amount of drinking water is introduced into the low temperature tank 5 from the beverage container 10 via the cold water supply pipe 51.

  During the sterilization process, the electromagnetic on-off valve 68 is opened, the electromagnetic on-off valve 57 is opened, and the electromagnetic on-off valve 58 is closed. At this time, the hot water for sterilization supplied from the sterilization pipe 67 passes through the inside of the cold water pipe 52 and flows into the vicinity of the lower end of the cold water supply pipe 51 as indicated by an arrow. Therefore, the inside of the cold water pipe 52 is also sterilized by heating with high-temperature hot water. The hot water flowing into the vicinity of the lower end portion of the cold water supply pipe 51 heats and sterilizes the inside of the cold water supply pipe 51 and the branch member 4, and then returns to the high temperature tank 6.

  As described above, in the first modified example, when the sterilization process is executed, the inside of the cold water supply pipe 51 and the inside of the cold water pipe 52 in addition to the branch member 4 are also heat sterilized. Therefore, even if bacteria or the like enter from the cold water cock 53 side, the bacteria and the like are periodically sterilized by heating, and the hygienic state is always kept good.

  FIG. 4 is a view showing a second modification of the beverage server of the present invention. In this modification, the path of hot water supplied from the sterilization pipe 67 to the cold water supply pipe 51 is different from that in FIG. In addition, the same code | symbol is attached | subjected to the member common with the drink server 1 of FIG. In the second modification, a heating jacket 521 is disposed on the outer periphery of the cold water pipe 52. A fluid can flow through the inside of the heating jacket 521. The sterilizing hot water discharged from the hot water circulation pump 66 flows from the sterilization pipe 67 into the end of the heating jacket 521 on the cold water cock 53 side, and passes through the inside of the heating jacket 521 as indicated by an arrow. Into the vicinity of the lower end of the cold water supply pipe 51.

  An electromagnetic on-off valve 68 is provided in a pipe connected to the vicinity of the lower end of the cold water supply pipe 51. As in the embodiment of FIG. 1, the electromagnetic on-off valve 68 is closed during normal use and opened during sterilization. Also in the second modified example, when the sterilization process is executed, the cold water pipe 52 in addition to the inside of the cold water supply pipe 51 and the branch member 4 is also heat sterilized. Therefore, even if bacteria or the like enter from the cold water cock 53 side, the bacteria and the like are periodically sterilized by heating, and the hygienic state is always kept good.

  FIG. 5 is a view showing a third modification of the beverage server of the present invention. In this modification, the structure for heat sterilization of the cold water pipe 52 is different from that of the second modification. In addition, the same code | symbol is attached | subjected to the member common with the drink server 1 of FIG. In the third modification, a pipe heater 522 is disposed on the outer periphery of the cold water pipe 52. The pipe heater 522 is for heating and sterilizing the cold water pipe 52 from the outer periphery by an electric current. The hot water circulation system for sterilization is the same as the embodiment of FIG.

  In the third modified example, hot water for sterilization is circulated during the sterilization process, and at the same time, a drive current is supplied to the pipe heater 522 to sterilize the cold water pipe 52 from the outer periphery. Therefore, even if bacteria or the like enter from the cold water cock 53 side, the bacteria and the like are periodically sterilized by heating, and the hygienic state is always kept good. In addition, the piping for the hot water circulation system for sterilization is simplified.

  As described above, according to the present invention, when the beverage container 10 is replaced, the inside of the cold water supply pipe 51 and the vicinity of the branching member 4 can be easily sterilized. There is no risk of bacteria entering the inside. Moreover, this sterilization process can be completed in a short time. Furthermore, the cost of the beverage server can be reduced. Further, since the hot water for sterilization is circulated only to the necessary portions, it does not consume extra energy for sterilization, contributing to energy saving. Furthermore, since the cold water in the low temperature tank 5 is not heat-sterilized, the flavor of natural water is not impaired.

  In addition, although the above embodiment gave and demonstrated drink water, such as mineral water, as an example as a drink, it is applicable also to arbitrary drinks other than drink water.

  ADVANTAGE OF THE INVENTION According to this invention, the drink server which can always pour out sanitary drinking water can be provided. Also, anyone can easily perform the sterilization treatment.
