FIG. 1 is an external perspective view of the beverage supply device, FIG. 2 is a water circuit diagram of the beverage supply device, and FIG. FIG. 4 is an exploded sectional view of the beverage storage part.

  First, with reference to FIG.1 and FIG.2, the external appearance structure of the drink supply apparatus 1 is demonstrated. The beverage supply device 1 has a vertically long box-like device housing 10 in which devices such as a cold water tank and a hot water tank described later are accommodated. A cup stage 11 on which a beverage cup A can be placed is provided on the front surface of the apparatus housing 10.

  An installation space 12 is formed on the top surface of the top plate 10 a of the apparatus body 10. An ultraviolet sterilizer 20 is installed in the center of the installation space 12 in the left-right direction. The ultraviolet sterilizer 20 uses a mercury lamp, uses an ultraviolet light emitting diode, or kills sterilization by ultraviolet pulse light. In addition, one beverage storage section (a beverage tank storing mineral water or the like) 30 is arranged on each of the left and right sides with the ultraviolet sterilizer 20 in between. A back plate 13 extends upward on the back side of the installation space 12, and two light shielding covers 14 that cover the installation space 12 are arranged side by side on the back plate 13. Each light shielding cover 14 is partitioned and formed by a plate material so as to cover the front surface, the upper surface, and the outer side surface of the installation space 12 when the installation space 12 is closed. Further, the rear end side of the upper surface of each light shielding cover 14 is pivotally supported on the back plate 13 by a hinge 14a, and is rotatable in the vertical direction as shown by a one-dot chain line double-headed arrow in FIG. Here, when each light shielding cover 14 is rotated upward, the installation space 12 of the beverage tank 30 is opened.

  Next, the water circuit of the beverage supply apparatus 1 will be described with reference to FIG. The beverage supply apparatus 1 has two beverage tanks 30, a cold water tank 40 and a hot water tank 50. Each beverage tank 30 is connected to water supply pipes 61a and 61b provided with water supply valves 60a and 60b. Each of the water supply pipes 61 a and 61 b is connected to a water supply common pipe 61 c provided with a pump 62. The downstream side of the water supply common pipe 61 c is bifurcated, one water supply branch pipe 61 d is connected to the bottom of the cold water tank 40, and the other water supply branch pipe 61 e is connected to the bottom of the hot water tank 50. Thereby, the beverage in the beverage tank 30 can be led to the cold water tank 40 and the hot water tank 50.

  In addition, beverage pipes 63 a and 63 b are connected to the upper portions of the cold water tank 40 and the hot water tank 50, and cold water and hot water are guided toward the cup stage 11 through the beverage pipes 63 a and 63 b. Here, the tips of the beverage pipes 63a and 63b serve as drinking water outlets 63a1 and 63b1 for water to be poured from the beverage reservoir 30, and nozzles and the like (not shown) are used as the running water outlets 63a1 and 63b1. The cup stage 11 is provided with a receiving container for receiving a beverage, for example, a beverage cup A. The beverage cup A receives the beverage that has flowed out from the flowing water outlets 63a1 and 63b1. Opening and closing devices 64a and 64b that perform water guiding control are installed in the middle of the beverage pipes 63a and 63b, and cold water is supplied or stopped by operating the opening and closing devices 64a and 64b. The opening / closing of each of the opening / closing devices 64a and 64b is detected by an opening / closing detection switch 65. Further, drain pipes 66 a and 66 b are connected to the upper portions of the cold water tank 40 and the hot water pipe 50, and the drain pipes 66 a and 66 b are connected to a drain common pipe 66 c provided with a check valve 67. Thereby, the drinks in the cold water tank 40 and the hot water tank 50 can be drained to the drain receiver 68 through the drain pipes 66a and 66b and the drain common pipe 66c.

  In the water circuit of the beverage supply device 1 configured as described above, the configuration of the beverage tank 30 installed in the water circuit will be described with reference to FIGS. 1, 3, and 4.

  Each beverage tank 30 includes a light transmissive tank portion 31 that contains a beverage, and an adapter portion 32 that is connected to a water outlet 31 a of the tank portion 31. As shown in FIG. 1, the tank portion 31 is formed in a cylindrical shape with a resin, and has a water outlet 31 a with a reduced diameter on the lower side. The inner surface of the peripheral wall 31b of the tank part 31 is coated with an antibacterial member. As the antibacterial agent of the antibacterial member 31c, an inorganic antibacterial agent such as silver, zinc or copper, or a titanium phosphate compound is used. In addition, it is desirable to use the light-transmitting antibacterial member 31c so that the ultraviolet rays irradiated from the ultraviolet sterilizer 20 are transmitted into the tank portion 31. On the other hand, when the antibacterial member 31c is not light-transmitting, for example, the antibacterial member 31c is appropriately coated on a part of the tank part 31c without coating the entire part, and ultraviolet rays are transmitted into the tank part 31c. You may make it do.

  The adapter unit 32 includes an upper adapter unit 321 and a lower adapter unit 322. The upper adapter part 321 is fixed to the water outlet 31a and has a cylindrical main body part 321a. In addition, an upstream water port 321b is provided at the inner center of the main body 321a, and the upstream water port 321b is opened and closed by an upper valve body 321c that can move up and down. The upper valve body 321c is always pulled downward (in the closing direction of the upper valve body 321c) by the coil spring 321d. On the other hand, the lower adapter portion 322 is disposed in the upper tube portion 322a that can be fitted to the upper adapter portion 321, the lower tube portion 322b that is connected to the water supply pipe 61a (61b), and the tube portions 322a and 322b. A lower valve body 322c is provided. The upper cylindrical portion 322a has a downstream water port 322d at the inner center, and the downstream water port 322d can be opened and closed by a lower valve body 322c. The lower valve body 322c is normally pulled upward (in the closing direction of the lower valve body 322c) by the coil spring 322e.

  These upper and lower adapter parts 321 and 322 are connected through the opening of the top plate 10a (a dashed line arrow in FIG. 3), and the tank part 31 is connected to the water supply pipe 61a (61b). Further, when connecting the upper and lower adapter portions 321 and 322, as shown in FIG. 4, the lower end of the upper valve body 321c hits the upper end of the lower valve body 322c and pushes down the lower valve body 322c, thereby opening the downstream water port 322d. Thereafter, after the downward movement of the lower valve body 322c is completed, the upper valve body 321c moves upward and opens the upstream water port 321b. Thereby, as shown by the solid line arrow in FIG. 4, the beverage in the tank portion 31 flows downward through the upstream / downstream water ports 321b and 322d, and the beverage flows through the water supply pipe 61a (61b).

  Next, the structure of the cold water tank 40 of the beverage supply apparatus 1 will be described with reference to FIG. The cold water tank 40 has a tank body 41 partitioned by a heat insulating wall. On the inner wall of the tank body 41, an evaporator 42, which is a refrigerant vaporizing mechanism portion of a refrigeration apparatus (not shown), is installed. Due to the refrigerant vaporization action of the evaporator 42, an ice bank 43 is formed in the tank body 41, whereby the beverage in the tank body 41 is cooled. Further, an ultraviolet sterilizer 44 (which is separate from the ultraviolet sterilizer 20) 44 for irradiating ultraviolet rays is installed in the tank main body 41 so as to sterilize the beverage in the tank main body 41 with ultraviolet rays. Further, a temperature sensor 45 for detecting the temperature inside the main body is installed in the tank main body 41.

  Then, the structure of the hot water tank 50 of the drink supply apparatus 1 is demonstrated with reference to FIG. The hot water tank 50 has a tank body 51 partitioned by a heat insulating wall. The tank main body 51 is provided with a heater 52 for heating the beverage in the tank main body 51. Further, a temperature sensor 53 for detecting the temperature inside the main body is installed in the tank main body 51. Further, a thermostat 54 for preventing airing is installed on the side wall of the tank body 51.

  In the beverage supply device 1 configured as described above, when cold water is poured into the beverage cup A, the opening / closing device 64a is opened. The opening / closing device 64a is detected by the opening / closing detection switch 65. Based on this detection signal, one of the water supply valves 61a and 61b is opened, and the pump 62 is further driven. Thereby, the beverage in the beverage tank 30 flows into the cold water tank 40 through the water supply pipe 61a and the water supply common pipe 61c. By the beverage that has flowed into the cold water tank 40, the cold water that has been stored in the cold water tank 40 is pushed out of the cold water tank 40 and supplied to the beverage cup A through the beverage pipe 63a.

  On the other hand, when hot water is poured into the beverage cup A, the opening / closing device 64b is opened. The opening / closing device 64b is detected by the opening / closing detection switch 65. Based on this detection signal, one of the water supply valves 61a and 61b is opened, and the pump 62 is further driven. Thereby, the beverage in the beverage tank 30 flows into the hot water tank 50 through the water supply pipe 61b and the water supply common pipe 61c. By the beverage that has flowed into the hot water tank 50, the hot water previously stored in the hot water tank 50 is pushed out of the hot water tank 50 and supplied to the beverage cup A through the beverage pipe 63b.

  According to the beverage supply apparatus 1 according to the present embodiment, the ultraviolet sterilizer 20 is installed on the top plate 10a, and each beverage tank 30 is irradiated with ultraviolet rays, so that the beverage tank 30 is sterilized and bacterial growth is prevented. Is done. In addition, since the antibacterial member 31c coated on the inner surface of the peripheral wall 31b of the beverage tank 30 suppresses the growth of bacteria in the beverage storage tank 30, the ultraviolet irradiation time can be shortened accordingly.

  FIGS. 5 (a) and 5 (b) show examples of changing the coating location of the antibacterial member. In the embodiment, the antibacterial member 31c is coated only on the peripheral wall 31b of the tank portion 33. However, as shown in FIG. 5A, the antibacterial member 321e is coated on the inner surface of the peripheral wall of the upper adapter portion 321. May be. Moreover, as shown in FIG.5 (b), you may make it coat the antimicrobial member 322f on the surrounding wall inner surface of the upper cylinder part 322a of the lower adapter part 322. FIG. Of course, both of the antibacterial members 321c and 322f may be coated, and further, in addition to the antibacterial member 31c of the above-described embodiment, these may be coated.

  Thereby, the place where the air outside the beverage tank 30 (the air in which bacteria float) is likely to enter is the adapter part 32. Since the antibacterial members 321e and 322f are arranged in the adapter part 32, the bacteria propagate. Sterilization of easy parts is surely performed.

  FIG. 6 shows a modified example of the antibacterial member. In the modification shown in FIG. 5 (b), an example in which the antibacterial member 322f is coated on the inner surface of the upper wall portion 322a of the lower adapter portion 322 is shown, but the present invention is not limited to this. For example, as shown in FIG. 6, an antibacterial member 322g in which an antibacterial agent is supported on a water-permeable material such as a porous body or fiber may be detachably accommodated in the upper tube portion 322a. Here, activated carbon or the like is used as the porous body, and a hollow fiber membrane module is used as the fiber. Thereby, since the antibacterial member 322g is detachable, it can be replaced as needed when the antibacterial performance is lowered.

  7 and 8 show the drive control of the ultraviolet sterilizer 20 of the beverage supply apparatus 1. Here, a microcomputer (hereinafter referred to as a microcomputer) 70 is used as a drive control device for the ultraviolet sterilizer 20. The microcomputer 70 has a CPU 71 and a memory 72. The CPU 71 receives signals from the sales signal sending device 73, the timer 74, and the ultraviolet sterilizer operation time setting device 75. Here, as sales signal sending device 73, in the above-mentioned embodiment, for example, an open / close detection switch (water injection detection means) 65 that outputs a drink extraction signal corresponds to this. The ultraviolet sterilizer operation time setting unit 75 can set a suitable time t1, for example, as the irradiation time of the ultraviolet sterilizer 20. The ultraviolet sterilizer control signal output from the microcomputer 70 is output to the ultraviolet sterilizer 20 through an ultraviolet sterilizer drive circuit 76 such as a relay. Hereinafter, the drive control of the ultraviolet sterilizer 20 will be described with reference to FIG.

  That is, the operation time t1 set by the ultraviolet sterilizer operation time setting device 75 is stored in the memory 72 (S1). Here, it is determined whether or not a beverage sales signal is output from the sales signal transmission device 73 (S2). If the sales signal is not yet output in step S2, the standby state is continued. On the other hand, when the sales signal is output, the ultraviolet sterilizer 20 is operated (S3). The operation time t1 of the ultraviolet sterilizer 20 is monitored by the timer 74 (S4). When the operation time t1 ends, the operation of the ultraviolet sterilizer 20 is stopped (S5), and the standby state is returned again.

  According to the drive control of the ultraviolet sterilizer 20, the beverage in the beverage tank 30 can be sterilized each time the beverage is sold, so that a sanitary beverage can be always poured.

  9 and 10 show another drive control of the ultraviolet sterilizer 20. In this drive control, an ultraviolet sterilizer operation time setting device 77 is used instead of the sales signal sending device 73, and the ultraviolet sterilizer operation time setting device 77 can arbitrarily set the operation start time of the ultraviolet sterilizer 20. It is like that. Since the other configuration is the same as that of the drive control, the description thereof is omitted.

  That is, the memory 72 stores the operation time t1 set by the ultraviolet sterilizer operation time setter 75 and the operation time T hours T1 set by the ultraviolet sterilizer operation time setter 77 (S1). Here, it is determined whether or not the operation time of the ultraviolet sterilizer 20 has been reached (S2). If the operation time T is not yet T1 in step S2, the standby state is continued. On the other hand, when the operation time is reached, the ultraviolet sterilizer 20 is operated (S3). The operation time t1 of the ultraviolet sterilizer 20 is monitored by the timer 74 (S4). When the operation time t1 ends, the operation of the ultraviolet sterilizer 20 is stopped (S5), and the standby state is returned again.

  According to the drive control of the ultraviolet sterilizer 20, the beverage in the beverage tank 30 can be sterilized periodically according to the time. For example, the operation time is set to midnight. Such a time zone is a time zone in which bacteria are most proliferated as the number of water injections is reduced, and ultraviolet sterilization is effectively performed.

  11 and 12 show another drive control of the ultraviolet sterilizer 20. In this drive control, the operation start timing of the ultraviolet sterilizer 20 is controlled by the sales signal sending device 73 and the non-sale time setting device 78. Here, the non-sale time set by the non-sale time setter 78 is a time interval between the beverage sale and the next beverage sale. For example, this time interval is arbitrarily set to a time t2 at which the bacterial growth is expected to be significant. Set to. Note that the same components as those of the drive control are denoted by the same reference numerals, and the description thereof is omitted.

  That is, the memory 72 stores the operation time t1 set by the ultraviolet sterilizer operation time setter 75 and the time t2 set by the non-sale time setter 78 (S1). Here, it is determined whether or not there is a sales signal (S2). If there is still no sales signal in this step S2, it is determined whether or not a non-sale time t2 has been reached (S3). If the non-sale time t2 has not yet been reached in step S3, the standby state is continued.

  On the other hand, when there is a sales signal in step S2, that is, when the beverage is poured out and sold, the timer 74 for measuring the non-sale time is reset (S4) and the process returns to the standby state. In the process of sequentially processing such steps S2 to S4, when the non-sale time reaches t2 in step S3, the ultraviolet sterilizer 20 is operated (S5). The operation time t1 of the ultraviolet sterilizer 20 is monitored by the timer 74 (S6). When the operation time t1 ends, the operation of the ultraviolet sterilizer 20 is stopped (S7), and the standby state is returned again.

  According to the drive control of the ultraviolet sterilizer 20, when the next water injection is not started by the predetermined elapsed time (non-sale time) after pouring the beverage, for example, this set time t2 is not suitable for the beverage. When it is predicted that the bacterial population will grow, when the time interval is set, the beverage in the beverage tank 30 can be hygienically managed efficiently.

  13 to 15 show another drive control of the ultraviolet sterilizer 20. In this drive control, instead of the sales signal sending device 73, an optical sensor 79 (reservoir detecting means) is used. As shown in FIG. 13, the optical sensor 79 is disposed so as to sandwich the tank portion 31 (the tank portion 31 is disposed between the light emitting element and the light receiving element), thereby detecting the beverage tank 30. It is supposed to be. Note that the same components as those of the drive control are denoted by the same reference numerals, and the description thereof is omitted.

  That is, the operation time t1 set by the ultraviolet sterilizer operation time setting device 75 is stored in the memory 72 (S1). Here, it is determined whether or not the beverage tank 30 is installed (S2). When it is determined in this step S2 that the beverage tank 30 is not installed, the standby state is continued, whereas when it is determined that the beverage tank 30 is installed, the ultraviolet sterilizer 20 is operated (S3). . The operation time t1 of the ultraviolet sterilizer 20 is monitored by the timer 74 (S4), and when the operation time t1 ends, the operation of the ultraviolet sterilizer 20 is stopped (S5).

  According to the drive control of the ultraviolet sterilizer 20, the beverage can be reliably sterilized when the beverage tank 30 is replaced.

  In this example, whether or not the beverage tank 30 is installed is detected by the optical sensor 79, but a piezoelectric sensor 80 may be used as the storage unit detection means as shown in FIG. That is, when the beverage tank 30 is installed (when the upper adapter 321 is connected to the lower adapter 322), the piezoelectric sensor 80 is installed in a portion of the upper cylinder portion 322a where the upper adapter 321 is installed. Thereby, the piezoelectric sensor 80 detects whether or not the beverage tank 30 is installed.

  The drive control of the ultraviolet sterilizer 20 has been described above. Next, the drive control of the pump 62 and the water supply valves 60a and 60b will be described.

  17 and 18 show drive control of the pump 62 and the water supply valves 60a and 60b. In addition, the same part as the structure demonstrated by the drive control of the said ultraviolet sterilizer 20 uses the same code | symbol, and abbreviate | omits the description. That is, the microcomputer 70 receives output signals from the sales signal sending device 73, the timer 74 and the non-sale time setting device 78, and based on these output signals, the pump 62 and the water supply valves 60a and 60b are connected to the pump drive circuit 81 and the water supply valve. Drive control is performed via a drive circuit 82.

  That is, as shown in the flowchart of FIG. 18, the memory 72 stores the time t2 set by the non-sale time setting unit 78 (S1). Here, it is determined whether or not there is a sales signal (S2). If there is still no sales signal in this step S2, it is determined whether or not a non-sale time t2 has been reached (S3). If the non-sale time t2 has not yet been reached in step S3, the standby state is continued.

  On the other hand, when there is a sales signal in step S2, that is, when the beverage is poured out and sold, the timer 74 for measuring the non-sale time is reset (S4) and the process returns to the standby state. In the process of sequentially processing such steps S2 to S4, when the non-sale time is time t2 in step S3, the operation of the water supply pump 62 and the water supply valves 60a and 60b is prohibited (pump 62; OFF, Water supply valves 60a and 60b; closed) (S5).

  According to the drive control of the ultraviolet sterilizer 20, when the next water injection is not started by the predetermined elapsed time (non-sale time) after pouring the beverage, for example, this set time t2 is not suitable for the beverage. When setting the time interval that is expected to grow to the bacterial population, beverage sales that are inconvenient in terms of hygiene can be reliably stopped.

  In the drive control, when the non-sale time t2 is reached, the operation of the water supply pump 32 and the water supply valves 60a and 60b is prohibited. However, as shown in FIG. 19, the non-sale time t2 is reached. In this case, the water supply pump 62 and the water supply valves 60a and 60b may be driven for a predetermined time, for example, for a time during which all the beverages stored in the beverage supply device 1 can be discharged (S1 to S5). As a result, all beverages that are unsanitary can be drained to the drain receiver 68 through the drain pipes 66a and 66b and the drain common pipe 66c.

  Moreover, although the said embodiment demonstrated the example which coated the antimicrobial member 31c, 321e, and 322f on the inner surface of the surrounding wall 31b of the drink tank 31, the surrounding wall of the main-body part 321a, and the inner surface of the surrounding wall of the upper cylinder part 322a, it is restricted to this. It is not a thing. For example, each peripheral wall may be formed of a resin kneaded with an antibacterial agent. In the above embodiment, the drive control operation time t1 and the non-sale set time t2 are commonly described in each example. However, the operation time t1 and the set time t2 may be set differently in each example. Good. Furthermore, although the optical sensor 79 and the piezoelectric switch 80 are used as detection means for the beverage tank 31, the present invention is not limited to this as long as the beverage tank 31 can be detected. Furthermore, although the opening / closing detection switch 65 of each opening / closing device 64a, 64b is used as the sales signal sending device 73, it is not limited to this. For example, a flow sensor (not shown) for detecting running water may be provided in the beverage pipes 63a and 63b, and a sales signal may be detected using the flow sensor.
