The 〇 junction 11 ' is formed into a double cylinder, the outer fine 彡 becomes the container The cylindrical tubular body for fitting 14a is formed into a cylindrical tubular body for insertion 11b in the JT portion. The peripheral wall of the inner wall 1 lb is formed with a Weikong nc having a common air flow. And the through hole 11d, and an opening portion 形成 is formed on the bottom surface.

That is to say, the material is returned to the upper part of the machine, and the mouth of the water is installed in the mouth of the J B. The mouth of the drink is installed in the water supply e, through the empty milk flow universal through hole.

=' Pass the separator! The through hole of the 8 and the separator 18 and the cold water PI PI: ’ itA warm water tank 13 and the cold water tank 12 I raise the water surface of the beverage water. When the bottom surface of the connecting portion U is closed, the opening portion of the bottom surface is closed, and the cold water is discharged from the If water. Next, in this state, the beverage water is taken from the water sputum (10) on the water side of the '18. Then, the separation is performed, and the state in which the disk is lowered by the water surface is released. The water enters the container B from the container ί 11 and is used for beverages. ·^士八杂. ° Under the machine. When the bottom knife of the take-up portion 11 of the water outlets 14 & 141 is stopped, the water level of the beverage rises, and the water surface reaches the container. As described above, the opening portion 116 is closed again, and the flow of the beverage water is stopped. The air in the beverage can be taken from the container B by the container B, and only the air in the air can be taken in through the air filter 16. At this time, the air transition unit 16 can prevent the inside of the water server such as a gray cloth or a sponge. In the air filter unit 16, when the nonwoven fabric is used, the communication property r is large to the rough (larger aperture) and the air permeability is good. Use a thin mesh t will not be able to take enough air (outside air) to the mouth of the container. Drinking water #水钱容ϋ B properly flow down, the low water outlet 14a, 201143870 14b accessibility. However, the foreign matter is taken in by a thicker mesh such as a non-woven fabric or a sponge, and the intrusion of a relatively large object is not sufficient, but the intrusion of the object is not sufficient. Further, the bacteria are not only passed through the two-rolling filter state, but also the water outlets 14a and 14b are invaded by fingers and the like. When it is frequently taken, it is disturbed by the inside of the service machine. The invading bacteria are difficult to reproduce. However, the == zone, the beverage water in the beverage water server does not move, and the fine ® is easy to breed. Therefore, in order to carry out the sterilization of the bacteria, a beverage water server (see, for example, Patent Document 5) having a twisting device (for example, Patent Document 2) and a beverage device having an ultraviolet lamp has been proposed. Patent Document Patent Document 1 Patent Document 2 Patent Document 3 Patent Document 4 Patent Document 5 曰本特开2006-076662号 曰本特开2009-083871号曰本本开2009-083868号 曰本许可证第4317259号In the case of the beverage water server equipped with the heating device, the piping system is extremely complicated, and the beverage water server itself is expensive, and the power consumption is increased, and the operating cost is reduced. Problems and the problem that the beverage water server cannot be made during the operation of the heating device. In addition, the beverage water server with the rabbit external line lamp has ultraviolet rays harmful to the human body and the eyeball, and the material guide for the battery-riding resin parts. ^ Rubber components are inferior to the problem. In addition, there is a beverage water supply spear with a hairline. Because the ozone is in the human body, there are (4) gases, * there are problems with the regulation of ozone gas concentration, and the odor of the odor is harmful to the flavor. In addition, with the problem of the 201143870 (4) placement and in view of the above facts, the object of the present invention is to provide a simple structure to prevent the fineness of the bacteria in the beverage water service machine. Breeding. In order to achieve the object, the beverage water server of the present invention comprises: a container portion that is connected to a mouth portion of the beverage water container by a loading and unloading method; and a water tank, below the capacitor portion, is drained from the container H Reading water; effluent = = using the beverage water stored in the water tank; the external gas inlet is connected to the f-water recording container through the Toshiqiu; and air filtration, n, to cover the outer & In the state of the inlet, the air filter is an (A) device in which an antibacterial member of the following (B) is provided. The filter (A) is composed of a porous film made of a fluororesin and a protective porous film fixed to the surface of the porous film made of the fluororesin, and the pore diameter of the porous film made of the gas-resin is set within a range of 〇.2 to 0.8 μm. The pore diameter of the porous membrane for protection is set to an air filter having a pore diameter of not more than that of the fluororesin. And (Β) consisting of a plurality of granular antibacterial agents and a water-permeable porous bag sealing the granular antibacterial agents, wherein the granular antibacterial agent is ion-bonded by low-density polyethylene and silver ion vermiculite. It is composed of an ion exchanger. ^ The present inventors believe that the hygiene management of the beverage water server should be realized in a simple structure, so that it is considered to prevent the invasion of bacteria with the intrusion of the outside air, instead of using the traditional intrusion in the beverage water server. At the same time, it is considered that the means for inhibiting the bacteria is caused by the intrusion of bacteria from the water outlet into the beverage water server due to the contact of the human hand and the finger to the water outlet. Therefore, the present inventors have repeatedly studied the formation materials and structures of the air filter which are known to prevent bacteria from being taken in with the outside air. In this smuggling, the gas is made of a gas resin as a forming material, and even if the pore diameter is small, it can be used as a porous film excellent in air permeability. Further, since the fluororesin is excellent in water resistance, it is suitable for use in a water beverage service machine. Further, in order to protect the fluororesin porous film 201143870 and maintain the filter performance, it is considered that the protective porous film is fixed to both surfaces of the fluororesin porous film. Secondly, according to this concept, the research is repeated. As a result, when the air filter for protecting the porous film was fixed to both surfaces of the fluororesin porous film, the following conclusion was found, that is, 'if the pore diameter of the fluororesin porous film is set within a range of ～0.8 μm? When the pore diameter of the porous film for protection is set to be larger than the pore diameter of the porous film made of the gas-resin, the gas permeability can be ensured for a long period of time, and the usability can be maintained, and the bacteria can be prevented from entering with the outside air. In addition, the food poisoning bacteria and the like are smaller than the pore diameter 〇2 to 0.8 μm of the porous film made of the fluororesin, however, due to the action of static electricity and the inertial impact and brown motion of the food poisoning bacteria or the like through the porous film made of the fluororesin. As a result, a porous film made of a gas-impermeable resin can be assumed. Then, the inventors of the present invention considered that the growth of bacteria in the beverage water server should be suppressed, and it is considered that an antibacterial member is provided in the water tank of the beverage water server, and the formation materials and structures of the antibacterial member are repeatedly studied. As a result, it has been found that the antibacterial member is composed of a plurality of granular antibacterial agents and a water-repellent capsule which seals the granular antibacterial agents, and is made of low-density polyethylene and silver ions. The granule-shaped antibacterial agent is ion-exchanged with the zeolite to form the granulated antibacterial agent, and the granulated antibacterial agent releases the silver ion in water, and the action of the silver ion can inhibit the growth of bacteria in the beverage water server. . Moreover, it has also been found that the granular antibacterial effect on the human body is adverse. That is, the 'inventors' set the specific antibacterial member 'in a simple configuration' by using the specific air filter as an air filter serving the beverage water, and in the water tank of the beverage water server. The present invention can be completed by preventing bacteria from invading with the intrusion of outside air and suppressing the growth of bacteria in the beverage water server. - The beverage water server of the present invention can prevent the bacteria from entering with the intrusion of the outside air because the outside air is introduced through the air filter of the (Α). On the other hand, the antibacterial member of the (Β) is placed in the water tank, for example, even if the bacteria invade from the water outlet, the breeding can be suppressed. Secondly, the use of the (Α;) air filter and the antibacterial components for hygienic management, and the complicated sterilizing device of the thief-steamed water machine can be realized with a simple structure. Therefore, there is the advantage of easy maintenance and hygienic management. 8 S' 201143870 The use of electricity. In particular, in the air filter of the (A), when the thickness of the fluororesin porous film is set to be in the range of 1 to 15 μm, and the thickness of the protective porous film is set to be in the range of 120 to 170 μm, the air filter can be used. The air filter has a more balanced aeration performance and bacterial intrusion prevention performance. In addition, the ratio of the low-density polyethylene and the ion exchanger (low-density polyethylene/ion exchanger) constituting the granular antibacterial agent is set at (7 〇% by weight/30% by weight). Within the range of ~(95% by weight/5% by weight), the average direct control of the granular antibacterial agent is set within a range of 3 to 10 mm, and the pore diameter of the water-permeable porous bag is set within a range of 50 to ΙΟΟμπι. When the volume ratio of the granular antibacterial agent in the aqueous porous bag is set in the range of 30 to 70%, the bacterial growth inhibiting performance of the antibacterial member can be further improved. [Embodiment] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. Fig. 1 is a schematic cross-sectional view showing an embodiment of a beverage water server of the present invention. As shown in Fig. 1, the beverage water server is equipped with a container connecting portion η, a cold water tank 12, a warm water, and a cold water side water outlet i4a, as in the conventional beverage water server (Fig. 8 and Fig.). , the warm water side water outlet i4b, the external air intake inlet 15, and the air filter 1 and the like. The same reference numerals are given to the same parts, and the description thereof is omitted. The second time, the application of the beverage water server, the air filter, the device 1: as the second

(In Fig. 3, the operation of the three-layer structure air damper i is shown, and the (outer air flow path) is covered by the air-tightly installed outer air inlet port 15 and the body 3 is heated. In addition, the air filter, the state (refer to the arrow shown in Fig. 3) is covered by the cover 4. 201143870, in addition to the beverage water service machine of the present embodiment, the general The beverage water service, (refer to Fig. 8), the unused antibacterial member 2 is disposed on the separator 18 in the cold water tank 12. The antibacterial member 2, as shown in Fig. 4, is composed of a plurality of granular antibacterial agents. 2a and a water-permeable porous bag 2b for sealing the granular antibacterial agent 2a (in addition, in Fig. 4, only a small number of the granular antibacterial agent 2a are shown), the granular 2a' is lying low The density polyethylene and the hetero ion are combined with the ion exchanger of the Buddha stone. The antibacterial member 2 is placed in the water tank (in the present embodiment, the cold water tank 12), and is another feature of the present invention. As shown in the death, the biggest feature of the beverage water server of the present invention is that the air is used as the air. Further, the specific antibacterial member 2 is provided in the water tank of the beverage water server. Further, the air filter 1 (see Fig. 2) constitutes the Λ月f-made boring film 1'. The forming material (gas-resin) shall be made of polytetrafluoroethylene film 1&, for example, biaxial stretching of _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ The temperature is ingenious, and the pore diameter is in the α2~ lipid porous film la. 'In this case, the pore diameter of the fluororesin porous film la (in the range of 〇2 to 〇_), ί ; "According to the method of Ϊ 。 。 该 该 该 该 该 该 该 该 该 该 该 该 该 该 该 该 该 该 该 该 该 该 该 该 该 该 该 该 该 该 该 该 该 该 该 该 该 该 该 该 该 该 该 该Installed in the adapter, and will be: the sample chamber of the multi-physical evaluation device of the 5th and the yoke porous material. The enthalpy of the hole 夤 material readability evaluation H reaches the maximum pressure ° ί line , the detection of the aperture and the curve of the amount of the thread are confirmed by the amount, and the drying curve (10) is the most undersized == =1 = the aperture of the singer a, by the distribution In addition, the porous m made of the fluororesin should be a non-woven fabric or a woven fabric made of a resin. The tree wax, the === 201143870, the external air intake cylindrical body 3 of the air filter 1 is installed In view of the simple structure, it is preferable that the resin is the same as the resin material of the external air intake cylindrical body 3, for example, polyethylene. Next, the two sides of the porous film la of the fluororesin are fixed for protection. In the method of the porous film 1b, for example, the protective porous film 1b is bonded to both surfaces of the fluororesin porous film 1a, and is heated and pressed. The air filter 制作 manufactured as described above is not only described above. It can fully ensure air permeability and has the property of preventing bacterial invasion. Further, as described above, since the pore diameter of the protective porous film 1b is set to be larger than the pore diameter of the fluororesin porous film la, the performance is affected by the fluororesin porous film la. Next, from the viewpoint of improving the performance, the thickness Å of the fluororesin porous film la should be set within the range of 2 to 9 μm. Further, the thickness of the protective porous film 1b should be set in the range of 12 〇 to 17 〇 μm, preferably about 145 μm. Here, the thickness of the I resin porous film la (in the range of 丨~;^^) can be confirmed by, for example, an electric field radiation type scanning electron microscope. In other words, the porous film la made of the fluororesin is very thin and flexible, and the porous film la of the fluororesin is embedded in a resin to be fixed. Next, a cross section of the fluororesin porous film la is formed by ion beam cross-section polishing (Cr〇ss section polisher XCP). The ion beam profile is a device for forming a cross section by irradiation with an ion beam, and is used for forming a cross section by mechanical polishing to cause deformation of the sample. Next, the cross section was observed by the electric field radiation type scanning electron microscope, and the range of the thickness was confirmed. Further, in order to alleviate the charging in this observation, gold may be applied to the fresh resin film of the resin to have a cross section. In addition, the air filter 1 has a particle trapping ratio of 99.9995% or more with respect to particles having a particle diameter of 〇.15 μηι in the specification, and an initial pressure loss of 245 Pa or less. The ULPA (Ultra Low Penetration Air) filter specified by the Air Filter is the same. The pressure loss, the smaller the value, indicates that the air permeability is superior. In addition, the external air intake cylindrical body 3 (see Fig. 3) of the air filter 1 is formed by the upper large diameter portion 3a and the lower small diameter portion. The 201143870 = and the boundary portion of the small diameter portion 3b are formed as a step portion. At the step portion (the bottom portion), the peripheral portion of the circular air filter 1 is thermally fused. Further, in the upper end edge of only j 3a, four convex portions 3C (the third figure is only two of the cross-sections) are disposed, and the upper end faces of the convex portions 3c are on the same day. ^ί The peripheral part supports the cover 4. Next, the flow path (refer to the arrow in Fig. 3) of the gap between the adjacent convex portions 3e is communicated with the hollow portion for taking in the outside air. In addition, in the figure f3, the symbol 3d is a 〇-shaped ring that is attached to the outer peripheral surface of the outer air take-up body 3, and the external air is taken into the tubular shape = 3 In the state of 15 , the outer air is taken into the outer body of the outer body 3 and the inner peripheral surface of the outer gas take-up population 15 is formed to be airtight. Further, the outside air intake is attached to the outside air intake port 15 from the Φ. The cover 4' is formed in a topped cylindrical shape. The top surface is formed as a curved surface which is gradually lowered from the center portion toward the peripheral edge 4, and the dust is deposited on the top surface, and the inner surface of the circumferential surface of the lid body 4 is evenly disposed. An engaging claw (not shown) that is detachably engaged with a large-diameter portion of the outer air intake cylindrical body 3 such as a lower end peripheral portion, and is detachably mounted by the engaging claw For the outside air, the person uses the button 3. Next, the cover 4 is attached to the upper portion of the gas take-off body 3 by reading the air transition device 1 to prevent dust and the like from contacting the air filter 1. On the other hand, the production of the particulate antibacterial agent 2a constituting the antibacterial member 2 (see Fig. 4) is, for example, 1 Torr. (To the extent that the low-density polyethylene has a squeaking degree of powder which binds silver ion ions to the ion exchanger of the zeolite, and the low-density polyethylene resin is not fully melted and remains in a void state Next, from the viewpoint of inhibiting the proliferation of bacteria, the ratio of low-density polyethylene to ion-crossing body (low-density polyethylene/ion exchanger) should be set at (7 〇 wt% / 3 〇). In the range of % by weight (95% by weight / 5% by weight), it is preferably (9)% by weight / 1% by weight. Further, the average diameter of the granular antimicrobial agent 2a should be set in the range of 3 to 1 〇. The mass of the granular antibacterial agent 2a having an average diameter of 6 mm is preferably about 53.3 mg/m. The ion exchanger is, for example, s represented by the following chemical formula (1). The silver content of the granular antibacterial agent 2a should be in the 〇

12 S 201143870 0.5% by weight, preferably in the range of 0.2 to 0.3% by weight. Further, this flat is an average value of any of the ten granular antibacterial agents 2a measured by a caliper gauge. When set, take [Chemical 1] M2/n〇· Na20 · Al2〇3 · 2Si02 · χΗ20...(1) (M : Ag and Zn and NH3) (n : 1 or 2, M type) (x: an arbitrary natural number) Here, the silver content ((^% (% by weight)) of the granular antibacterial agent 2a can be confirmed by, for example, inductively coupled plasma mass spectrometry. That is, first, The acid-protecting agent 2a is added to the granular antibacterial agent 2a to ash the granular antibacterial agent 2a. Then, the ash-treated person is treated with hydrofluoric acid and then melted with potassium sulphate. Then, the dissolution = 1 acid' Then, the volume is adjusted by pure water. Secondly, the silk-inductive concentrator is used to confirm the content of the silver. In addition, the water-permeable porous bag 2b of the anti-g member 2 should be a non-woven fabric made of resin or For the resin, from the viewpoint of strength and the like, for example, t is preferable to the composite material of the 曱fee 酉曰 t and t 浠 。. In addition, the quality of the woven fabric should be set at 17.0 to 27.0 g/m 2 . The width is preferably 22.4g/m2. The thickness of the non-woven fabric is set to be in the range of 0.05 to 15 mm. In addition, the non-woven fabric is used in terms of good water permeability. The pore diameter 2 s is further in the range of 50 to 1 〇〇μπι. Next, when the granular antibacterial agent 2a is sealed in the pore of the water-permeable porous pouch, the granulated anti- _ ^ heat-sealed the peripheral portion of the non-woven fabric or the like And the granule-like antibacterial agent 2a and the beverage water are more suitable for the glutinous glutinous glutinous glutinous glutinous glutinous glutinous glutinous glutinous glutinous glutinous hydrazine In view of the above, the capacitive solution of the water-repellent portion 2a should be set to be in the range of 3 () to 7 (%), and in the present embodiment, the anti-secure member 2 is placed in the present embodiment. In the separator 18, it may be disposed under the separator 18/"inside 13 201143870. In addition, in the present embodiment, two water tanks of the cold water tank 12 and the warm water tank 13 are disposed, however, only In this case, the separation sling 18 is not required, and the position of the antibacterial member 2 can be any position in the water tank. Next, for the embodiment, a comparative example will be described. However, the present invention does not. The invention is limited to the embodiment. The embodiment prepares the beverage water server shown in Fig. 1. The air filter is made by A sheet formed by heating a porous film made of polyethylene (thickness: 145 μm) on both sides of a porous film made of PTFE (thickness: 〇1), NEUR〇FINE (shown by the dealer), total thickness 300 μπι) It is punched into a circle having a diameter of 22.8 mm. The pore diameter of the PTFE porous membrane of the air filter is determined by the bubble point method, and is formed within the range of 〇2: 〇.8 μιη. Further, the air filter The particle collection rate of the ULPA filter specified by the melon 28122 is 99.9995% or more and the initial pressure loss is 245 Pa or less. Next, 'the peripheral portion of the circular air filter is supersonic (the oscillating disk output is 1200 W, the oscillation frequency is 15.15 ± 15.15 kHz, the dissolution time is 0.2 seconds, and the holding time is 0.4 seconds), and the hot melt is covered. The hollow portion of the cylindrical body for gas intake (the flow path of the external air). The flow path of the external air intake cylindrical body was 14 mm. Further, the granular antibacterial agent constituting the antibacterial member is composed of an ion exchanger in which 90% by weight of low-density polyethylene and 1% by weight of silver ion ions are bonded to the zeolite, and is heat-formed to have an average diameter of 6 mm (53.3). (M/s) (manufactured by SINANEN ZEOMIC CO., LTD., PB6LJ10-1: silver content: 0.23 wt%). Next, 3 μg of the granular antibacterial agent was weighed, and a non-woven fabric (22.4 g/m 2 , a pore diameter 50 to ΙΟΟ μηη) having a thickness of 0.10 mm composed of a composite material of polyethylene terephthalate and polyethylene was placed. It is a bag-shaped (170mmx90mm) water-permeable porous bag sealed with heat sealing. The granular antibacterial agent inside the water-permeable porous bag occupies a volume ratio of 5 Å/0. Here, the bubble point method is carried out in the following manner. Namely, first, the porous film made of fluororesin was immersed in Galwick (fluorine-based test solution, surface tension: 0.0157 N/m) under atmospheric pressure. Next, measurement was carried out using a porous material multi-physical property evaluation apparatus (Perm-Porometer: CFP-1200AEXLCBBJ, manufactured by PMJ Corporation, USA). As a result, the "cumulative filter out-of-flow pore diameter" map shown in Fig. 5 and the sixth graph are shown.

14 S 201143870 "Pore size distribution vs average aperture" map. From the above figures, it was confirmed that the vicinity of the pore diameter of 0.39 μηη was the maximum peak, and the pore diameter was in the range of 0·2 to 0.8 μιη. Further, it was confirmed that the average flow pore diameter was 〇·389 μmη, and the maximum pore diameter was 0.386 μιη. In addition, the silver content of the granular antibacterial agent (0.23 wt%) was confirmed by an inductively coupled plasma mass spectrum of an inductively coupled plasma mass spectrometer (ICPS-8100, manufactured by Shimadzu Corporation). [Comparative Example 1] In the beverage water server of the present embodiment, the air filter is installed in a cylindrical body for taking in an external air by using a polyethylene sponge (a circular shape having a diameter of 22.8 mm and a thickness of 5 mm). Hot Melt). The other parts are the same as the above embodiment. [Comparative Example 2] In the case of the beverage water server of the present embodiment, the antibacterial member is not provided. The other parts are the same as the above embodiment. [Comparative Example 3] In the beverage water server of the present embodiment, the air filter is installed in a cylindrical body for taking in an external air by using a polyethylene sponge (circle of 22.8 mm in diameter and thickness of 5 mm). Hot Melt). In addition, no antibacterial members have been provided. The other parts are the same as the above embodiment. [Analysis method of the number of the populations of the common bacteria] The beverage water server of the above-described examples and Comparative Examples 1 to 3 was installed in an office floor (area 6 〇〇 m2) in which a business person engaged in business operations was installed. Next, for each beverage water server, the general bacterial population analysis was carried out for 14 days in the following manner, as shown in Fig. 7. (a) First, the beverage water server is sterilized and washed by hot water sterilization and alcohol sterilization. (b) Next, mineral water (Higashinihon Air Water energy INC., AW·

Water) 12L gallon bottles are installed in each beverage water server. (6) Next, take 5 to 111 tons of mineral water from the cold water side outlet and discard it. The side water outlet uses the water of the rainbow to the capacity of 1 (8). The ethylene-based halogen-killing bottle (SANSEI MEDICAL Ca, LTD., model 15 201143870 • ^2105) 'in the petri fllm dish (Sumitomo 3M) The system, model 64〇〇ac, and the inoculation area of the culture dish 2〇cm2) were cultured for general bacteria. (7) After 48 hours, the number of populations of Petri film culture dishes was visually calculated at a dilution ratio of 1 time. At this time, when the number of the population exceeds 250, the average value of the number of populations in the icm2 grid of the Petri film is obtained by multiplying it by 2 times, and the number of populations is estimated. In addition, the upper limit of the population when the dilution ratio is 1 time is 2,500. ® For each beverage water server, the number of groups is the same as (c) to (e) above. As shown in Fig. 7, when the beverage water server of the embodiment was completed, it was confirmed that there was general bacteria in the 14th day. On the other hand, in the case of the beverage water server of the comparative example, the general bacteria were confirmed from the ninth time, and then there was a slight increase, and the number of bacteria increased rapidly after the uth day. From the above facts, it can be seen that the comparative example i of the air filter having a relatively large mesh has a general bacterial invasion, and until the ninth, the bactericidal effect is obtained by the action of the antibacterial member, however, after that, it is generally The invasion of bacteria exceeds the ability of antibacterial components to inhibit bacterial growth. Further, in the case of the beverage water server of Comparative Example 2, the general bacteria were confirmed from the second day, and thereafter, there was a slight increase, and the number increased after the seventh time. From the point of view, in Comparative Example 2, the infiltration of the general bacteria can be prevented to some extent by the air filter having a fine mesh. However, since the antibacterial member is not activated, the probiotics start to proliferate when they invade, and thus cannot be obtained. The control of the number of groups. Next, in the case of the beverage water server of Comparative Example 3, the general bacteria were confirmed from the second sputum, and then there was a slight increase, and after the third day, the surge was increased, and the upper limit reached 2,500 on the 12th day. In this test, since the upper limit is set to 25, and in the seventh figure, it is 2,500 after the 12th day. However, the 12th day may continue to proliferate. From the above, in Comparative Example 3, since the mesh of the air filter was thick, the bacteria were easily invaded, and the general bacteria invading easily proliferated because there was no antibacterial member. From the above facts, it can be known that the beverage water server of the embodiment, together with the specific air filter and the specific antibacterial member, can effectively suppress the population of the general bacteria. Further, in the above-described embodiment, the thickness of the PTFE porous film of the air filter and the thickness of the polyethylene porous film were changed, and the population number analysis of the general bacteria was carried out as described above. The thickness is set in the range of 丨~^哗
