In addition, the energy consumption is increased by the equipment of two pumps.

  Moreover, in the cold / hot drinking water server of patent document 2, cooling of the drinking water of a water storage part cannot be avoided. In Patent Document 2, paragraph [0004] states that “the storage unit 43 is not cooled as much as the cold water unit 44”, which indicates that cooling of the storage unit is unavoidable. Therefore, in the cold / hot drinking water server of patent document 2, since the cooled drinking water is heated and warmed, energy will be wasted.

  The present invention has been made to overcome the disadvantages of the conventional invention. The cold and hot drinking water server of the present invention is equipped with two drinking water supply bottles and one hot water tank. A cold water bottle, which is one of the drinking water bottles, is arranged at the top (upper) and supplies cold water by natural outflow. The cold water bottle may be cooled. The remaining hot water bottle, which is one drinking water bottle, is arranged in the middle part (middle stage) and supplies drinking water to the warm water tank arranged in the lowermost part (lower stage) by natural outflow. The drinking water is stored as hot water in a heated state in the hot water tank, and the hot water is provided to the user by being pumped to the middle or upper stage by a pump. The cold water bottle and the hot water bottle are inclined at the bottom so that the drinking water in the bottle is collected at the water outlet of the bottle and the capacity of the usable drinking water in the bottle is increased.

  According to a fifth aspect of the present invention, in any one of the first to fourth aspects, the hot water bottle is a water bag made of a flexible material, and the interior of the water bag is decompressed, A cold and hot drinking water server in which the water bag contracts in accordance with a decrease in the amount of water in the water bag.

  According to a sixth aspect of the present invention, in the first to fifth aspects, a cold and hot drinking water is provided that includes a front tilting unit that tilts the bottom surface of the cold water bottle forward and collects the water in the cold water bottle near the cold water valve. It is a server.

  A seventh aspect of the present invention is the first to sixth aspects of the present invention, provided with a front inclination means for inclining the bottom surface of the hot water bottle forward, and collecting the water in the hot water bottle near the hot water outlet. It is a water server.

  According to an eighth aspect of the present invention, in any one of the first to seventh aspects, the upper stage is provided with a cold water bottle replacement door in which the cold water bottle is opened at least forward and upward in the open state. It is a cold and hot drinking water server that enables replacement of water bottles.

  A tenth aspect of the present invention is the cold and hot drinking water server according to any one of the first to ninth aspects, wherein an upper holding plate drain is provided on the holding plate of the cold water bottle, and the stored water on the holding plate is drained.

  An eleventh aspect of the present invention is the cold and warm drinking water server according to any one of the first to tenth aspects, wherein a drain plate is provided on the holding plate of the hot water bottle, and drained water is drained from the holding plate. is there.

  A twelfth aspect of the present invention is the cold and hot drinking water server according to any one of the first to eleventh aspects, wherein a hot water tank drain is provided at the bottom of the hot water tank and water can be drained from the hot water tank. .

  According to a thirteenth aspect of the present invention, in any one of the first to twelfth aspects, the upper stage, the middle stage, and the lower stage are formed in one vertically long substantially rectangular parallelepiped box, and the external structure and the internal structure are aggregated. It is a cold and hot drinking water server that is downsized.

  According to the first aspect of the present invention, cold water is provided by natural outflow from a cold water bottle that supplies only cold water, and hot water is provided by hot water pumping by a hot water tank that supplies only hot water, Furthermore, since the drinking water is supplied to the hot water tank from the hot water bottle that is systematically independent of the cold water bottle, it is possible to provide an energy-saving, simple structure and hygienic cold / hot drinking water server.

  With the cold and hot drinking water server according to the present invention, cold water and hot water can be supplied at a height from the user's head to the chest, so that cold water and hot water can be supplied at a position where the user's arm is most easily reached. In the conventional drinking water server only by natural outflow, since the supply position is low, it is inconvenient because the user needs to extend the arm to the bottom. The drinking water server of the present invention solves this inconvenience.

  The cold and hot drinking water server of the present invention has an advantage that the structure is simple compared with that of the cited document 1. In Cited Document 1, since a pump is required in both the cold water tank and the hot water tank, the structure is complicated, the energy consumption is large, and the possibility of failure is high. In the present invention, since only one pump is required, the structure is simplified, the possibility of failure is reduced, and the energy consumption is reduced.

  Moreover, the cold / hot drinking water server of this invention becomes energy-saving compared with that of the cited reference 2, and is hygienic. In Cited Document 2, since the cooled water is heated to be warm water, energy loss occurs. In addition, an excessive load is generated on the heater, so that a failure is likely to occur. In the cited document 2, there is a possibility that cross-contamination is caused by backflow from the hot water tank to the cold water tank. In the present invention, since the cold water providing system and the hot water providing system are completely independent, there is no possibility that the cold water enters the hot water providing system, and there is no possibility that the hot water enters the cold water providing system. Thus, there is no possibility of energy waste and cross-contamination.

  The material and shape of the cold water bottle and the hot water bottle in the present invention are not limited. As the material of the bottle, plastic, glass, metal and the like can be used. However, plastic is the most preferred material for the bottle because it is lightweight. Further, these bottles may be flexible bags or rigid bottles. However, in order to simplify the supply of the bottle and drinking water, it is desirable that the cold water bottle and the hot water bottle have the same material and shape.

  The cold water bottle in the present invention may be cooled. In this case, the cold water bottle needs a member having resistance to cooling. However, any of the above materials is resistant to cooling and is suitable for direct cooling of a cold water bottle.

  The hot water pump in the present invention is more efficient if it is installed further below the hot water tank installed in the lower stage. However, it may be installed above the hot water tank. Moreover, you may install not in the lower stage but in the middle stage or the upper stage. By installing the hot water pump above the hot water tank, the hot water pump can be prevented from being shielded by the hot water tank, so that the hot water pump can be easily maintained.

  According to the second aspect of the present invention, since the cold water bottle is cooled by the cooling means to obtain the cold water, it is possible to provide low temperature (around 4 ° C.) cold water using a simple mechanism. As described above, plastic, glass, metal, and the like can be considered as the material for the cold water bottle, but cold resistance around 4 ° C. can be easily ensured regardless of which material is used. However, plastic is preferred because it is the lightest. Moreover, as a cooling means of the cold water bottle in this embodiment, heat pump cooling using a cooling medium, Peltier cooling using an electrothermal effect, and the like can be considered. Further, a cooling medium such as ice may be supplied around the cold water bottle.

  According to the third aspect of the present invention, since cooling is performed using a cooling medium, cooling can be performed by a mechanism using the same heat pump effect as a commercially available refrigerator, and an established technique is used. Thus, cooling can be performed. There are many types of cooling media that can be used. Isobutane, which is most frequently used as a cooling medium at present, is most preferable from the viewpoint of availability and technical ease. However, chlorofluorocarbon, ammonia and carbon dioxide can also be used.

  According to the fourth aspect of the present invention, a bag made of a flexible material and having a volume reduced as the supply of cold water progresses is used as a cold water bottle. A simple cold water bottle can be used and the cold water can be kept hygienic.

  Since the bag here is extremely thin compared to a rigid bottle, it is lightweight and therefore easy to carry after drinking water, and it is easy to remove empty bottles after use. Becomes easier. Also, the bottle is very cheap and easy to recycle.

  Further, since the volume is reduced by providing cold water, it is not necessary to introduce air from outside into the bottle, unlike a rigid bottle. Therefore, since contamination by dust, tobacco dust, pollen, mold spores, bacteria, etc. existing in the air does not occur, the cold water in the bottle can be kept hygienic.

  According to the fifth aspect of the present invention, since the bag made of a flexible material and having a volume reduced as the supply of drinking water to the hot water tank proceeds is used as a hot water bottle, it is lightweight. In addition, a hot water bottle that can be easily replaced and recycled can be used, and the hot water can be kept hygienic.

  Since the bag here is extremely thin compared to a rigid bottle, it is lightweight and therefore easy to carry after drinking water, and it is easy to remove empty bottles after use. Becomes easier. Also, the bottle is very cheap and easy to recycle.

  In addition, since the volume is reduced by providing hot water, unlike the rigid bottle, it is not necessary to introduce air from outside into the bottle. Therefore, since contamination by dust, tobacco dust, pollen, mold spores, bacteria, etc. existing in the air does not occur, the hot water in the bottle can be kept hygienic.

  According to the sixth aspect of the present invention, the bottom surface of the chilled water bottle is inclined forward, and the water in the bottle is collected near the chilled water valve. It can be used efficiently.

  In conventional cold water bottles, the bottom surface of the bottle is substantially horizontal, so that there is a large amount of water existing below the cold water valve that cannot flow out naturally. Therefore, the volume of water that cannot be supplied, that is, the dead volume is large. Since the cold water bottle of this embodiment is inclined forward, the dead volume is small. Therefore, since the ratio of the water which can be utilized is large, cold water can be provided efficiently.

  As a method for inclining the cold water bottle forward, there is a method in which a substantially flat holding plate for holding the bottle from the lower side is inclined forward, and this method can be applied to both a rigid bottle and a flexible bottle. Further, when the holding plate is not used, there is a method of tilting the bottle forward by the arrangement of the side holders, and this method is used when the bottle has rigidity and the bottom surface of the bottle is substantially flat. It is valid.

  Another type of bottle with reduced dead volume is a bottle in which the lower volume of the bag is reduced by using a flexible bag as a bottle and forming the bag holding plate into a V shape. It is done. However, in such a bottle, since the V-shaped processing of the holding plate is required, the manufacturing process becomes complicated. When the bottle has rigidity, even if the holding plate is V-shaped, the bottom surface of the bottle is not V-shaped, so that the dead volume is not reduced.

  The bottle in this embodiment may have a substantially flat bottom surface. Therefore, the bottle in the present embodiment is already commercially available and can be formed simply by tilting the rigid bottle having a substantially flat bottom surface forward. When a flexible material is used for the bottle, the bottle in this embodiment can be formed simply by inclining the substantially flat holding plate forward, so that the manufacturing of the holding plate is simplified.

  According to the sixth aspect of the present invention, the bottom surface of the hot water bottle is inclined forward, and the water in the bottle is gathered near the hot water spout, thus reducing the residual amount of water in the bottle, The bottle can be used efficiently.

  In the conventional warm water bottle, since the bottom surface of the bottle is substantially horizontal, there is a large amount of water that cannot be naturally discharged from the hot water spout. Therefore, the volume of water that cannot be supplied, that is, the dead volume is large. Since the hot water bottle of this embodiment is inclined forward, the dead volume is small. Therefore, since the ratio of the water which can be utilized is large, the water for warm water can be provided efficiently.

  As a method of inclining the hot water bottle forward, there is a method of inclining a holding plate for holding the bottle from the lower side forward, and this method can be applied to both a rigid bottle and a flexible bottle. Further, when the holding plate is not used, there is a method of tilting the bottle forward by arranging the side holders, and this method is effective when the bottle has rigidity.

  Another type of bottle with reduced dead volume is a bottle in which the lower volume of the bag is reduced by using a flexible bag as a bottle and forming the bag holding plate into a V shape. It is done. However, in such a bottle, since the V-shaped processing of the holding plate is required, the manufacturing process becomes complicated. When the bottle has rigidity, even if the holding plate is V-shaped, the bottom surface of the bottle is not V-shaped, so that the dead volume is not reduced.

  The bottle in this embodiment may have a substantially flat bottom surface. Therefore, the bottle in the present embodiment is already commercially available and can be formed simply by tilting the rigid bottle having a substantially flat bottom surface forward. When a flexible material is used for the bottle, the bottle in this embodiment can be formed simply by inclining the substantially flat holding plate forward, so that the manufacturing of the holding plate is simplified.

According to the 8th form of this invention, since it has the cold water bottle replacement | exchange door which can be opened at least ahead and upwards, replacement | exchange of a cold water bottle can be performed easily. A normal replacement door is opened only forward, but such a replacement door has many restrictions. With the opening only at the front, it is difficult to lift the bottle upward, so that the replacement of the bottle becomes inconvenient. By installing the replacement door in this embodiment, it is easy to lift the bottle upward, and therefore it is easy to replace the bottle.
Furthermore, an exchange door can be provided on the left and right sides of the cold water bottle, and the left and right sides of the bottle can be opened. In this case, the replacement of the bottle is further simplified.

  According to the ninth aspect of the present invention, the hot water bottle can be opened at least forward and upward by pulling the hot water bottle forward, so that the hot water bottle can be easily replaced.

  It is difficult to open the front and top of the hot water bottle compared to the cold water bottle. In the middle stage where the hot water bottles are installed, it is necessary to provide a mechanism for removing the upper stage in order to provide an exchange door that opens upward, which is impractical. Instead of removing the upper stage, the upper part of the hot water bottle can be opened by pulling the hot water bottle forward, facilitating replacement of the hot water bottle. The drawer mechanism in this embodiment is most preferably a slide type in which the holding plate is placed on the rail.

  According to the tenth aspect of the present invention, since the holding plate (that is, the upper holding plate) of the chilled water bottle is equipped with the upper holding plate drain as a drainage mechanism, the accumulated water on the holding plate can be easily removed. Therefore, a sanitary environment can be maintained in the holding plate.

  Water is likely to be generated on the holding plate due to leakage of a bottle at the time of replacement. In particular, when the water bottle for chilled water is cooled, moisture in the atmosphere is condensed, and this dew water collects on the holding plate and becomes the accumulated water, so that the problem of accumulated water becomes more serious. By using the drain of this embodiment, the above problem can be solved.

  According to the eleventh aspect of the present invention, since the holding plate (that is, the middle holding plate) of the hot water bottle is equipped with the middle holding plate drain which is a drainage mechanism, the accumulated water can be easily removed and is hygienic. You can keep the environment. In the hot water bottle, dew condensation is not an important problem, but water may leak when the bottle is replaced. Therefore, it is important to remove the retained water from the holding plate.

  According to the twelfth aspect of the present invention, since the hot water tank is equipped with the hot water tank drain as a drainage mechanism, unnecessary water can be easily removed from the hot water tank. Prior to cleaning and repairing the hot water tank and transporting the cold and hot drinking water server, it is necessary to remove the water inside the hot water tank. This form of drain facilitates the removal of this water.

  According to the thirteenth aspect of the present invention, since the upper, middle and lower stages are integrally formed in one box, the parts can be arranged close to each other, making the whole compact. Can be manufactured.

It is a side perspective view of a cold and hot drinking water server. It is side surface perspective drawing of the upper stage in case the water bottle exchange door for cold water is in an open state. It is a front perspective view of a cold and hot drinking water server. It is a top view of the cold and hot drinking water server when the hot water bottle replacement door is in an open state. It is a conceptual diagram which shows the comparison of the effect of the conventional holding plate and the effect of the holding plate in this invention. It is a perspective view which shows drawer | drawing-out of the hot water bottle by a drawer mechanism. It is a partial side sectional view in case a warm water pump is installed in the upper part of a warm water tank in the state where a middle stage maintenance board is horizontal.

  FIG. 1 is a side perspective view of the cold and hot drinking water server 1. The cold and hot drinking water server 1 is formed of an upper stage 10, a middle stage 30, and a lower stage 50. In the upper stage 10, a cold water bottle 11 is installed, and cold water is stored in the bottle 11. Since the cold water bottle 11 in FIG. 1 is a flexible bag, no air hole is required. However, the cold water bottle 11 may have rigidity, and in that case, it is necessary to equip the air hole.

  The cold water bottle 11 is provided with a cold water valve 12, and the cold water naturally flows out by gravity in the valve 12 and is provided to the user. In FIG. 1, the valve 12 is directly coupled to the bottle 11. However, the bottle 11 and the valve 12 may be coupled by a hose or a pipe.

  The upper stage 10 is equipped with a cold water bottle replacement door 21. The exchange door 21 in FIG. 1 is opened at the front and top in the open state, so that the bottle 11 can be easily exchanged. The replacement door 21 may be formed integrally or a plurality of parts. Further, an exchange door that opens forward and an exchange door that opens upward may be provided separately. In FIG. 1, the left and right sides of the cold water bottle 11 are not opened. However, the water bottle replacement door 21 for cold water may be one that opens left and right as well as forward and upward. In addition to the replacement door 21, an additional replacement door that opens left and right may be provided. In order to make it possible to visually check the remaining amount of drinking water in the cold water bottle 11, the replacement door 21 is preferably made of a transparent material. By making the material of the replacement door 21 transparent plastic, it is possible to obtain a cold water bottle replacement door 21 that is transparent and lightweight and can be easily opened and closed.

  A substantially flat upper holding plate 22 is disposed below the upper stage 10, and the cold water bottle 11 is supported on the upper holding plate 22. In FIG. 1, the upper holding plate 22 is cooled, and the drinking water in the water bottle 11 is cooled by this cooling. In FIG. 1, the upper holding plate 22 is inclined forward, and the dead volume (volume of unusable drinking water) is reduced by collecting cold water near the cold water valve.

  The upper holding plate 22 is equipped with an upper holding plate drain 23, and the drain water formed on the upper holding plate 22 is removed by the drain 23. As described above, since the upper holding plate 22 is cooled, the accumulated water formed by the condensation of water is likely to occur. The upper holding plate drain 23 removes this accumulated water and keeps the upper holding plate 22 hygienic.

  On the left side, the right side, and the rear side of the cold water bottle 11, cold insulation plates 24 are installed. These cold insulating plates 24 are formed of a heat insulating material such as styrene foam as a material, and maintain the cooling state of the cold water bottle 11. Further, in order to facilitate replacement of the cold water bottle 11, the cold insulating plate 24 may be openable so as to open the periphery of the water bottle 11.

  In FIG. 1, a hot water outlet 55 is installed in the upper stage 10, and hot water is provided from the outlet 55. The hot water here is supplied from the lower stage 50. Therefore, the hot water outlet 55 is independent from the cold water supply system including the cold water bottle 11 and the cold water valve 12. In FIG. 1, the hot water outlet 55 is provided in the vicinity of the cold water valve 12, and the arrangement position is the lower part of the upper stage 10. However, the arrangement position of the hot water outlet 55 may be the middle stage 30. In FIG. 1, since the hot water outlet 55 is installed at the height of the chest of the user, it is easy to use.

  A middle stage 30 is disposed below the upper stage 10. A warm water bottle 31 is installed in the middle stage 30. Drinking water is supplied from the bottle 31 to the lower part 50. The drinking water is stored as warm water in the lower part 50. Since the hot water bottle 31 in FIG. 1 is a flexible bag, it does not require an air hole. However, the hot water bottle 31 may be rigid, and in that case, it is necessary to provide an air hole. The hot water bottle 31 itself does not need to store drinking water as hot water. Therefore, the hot water bottle 31 does not need to have heat resistance, and can therefore be manufactured from the same material as the cold water bottle 11. The hot water bottle 31 is preferably manufactured from the same material and structure as the cold water bottle 11 and has mutual interchangeability from the viewpoints of drinking water supply and ease of maintenance. In FIG. 1, the hot water bottle 31 is not heated. However, the bottle 31 may be heated to such an extent that the material of the bottle 31 does not deteriorate.

  The warm water bottle 31 is provided with a warm water spout 32. The water discharge port 32 may have the same structure as the cold water valve 12. The water discharge port 32 is connected to a middle / lower connection pipe 33, and the pipe 33 is connected to the lower stage 50. The drinking water from the bottle 31 naturally flows out through the water outlet 32 and the pipe 33 and is supplied to the lower stage 50.

  A warm water bottle replacement door 41 is provided in front of the warm water bottle 31 in the middle stage 30. In FIG. 1, the replacement door 41 opens sideways and only the front of the bottle 31 is opened. In order to open the upper side of the hot water bottle 31, a drawing mechanism for the bottle 31 may be provided in the middle stage 30. In order to make it possible to visually recognize the remaining amount of drinking water in the bottle 31, the replacement door 41 is preferably made of a transparent material. By making the material of the replacement door 41 transparent plastic, it is possible to obtain the hot water water bottle replacement door 41 which is transparent and lightweight and can be easily opened and closed.

  In the lower part of the middle stage 30, a substantially flat middle stage holding plate 42 is provided, and the warm water bottle 31 is supported by the middle stage holding plate 42. The middle holding plate 42 in FIG. 1 is inclined forward. By this inclination, the dead volume (volume of the unusable drinking water) in the bottle 31 can be reduced, and the drinking water in the bottle 31 can be used effectively. The middle stage holding plate 42 is equipped with a middle stage holding plate drain 43 to remove the accumulated water generated on the middle stage holding plate 42.

  A lower stage 50 is disposed below the middle stage 30. The lower stage 50 is equipped with a hot water tank 51 and is stored in the hot water tank 51 as hot water in a heated state. By installing the hot water tank 51 in the lower stage 50, the center of gravity of the cold / hot drinking water server 1 can be lowered, and the stability of the server 1 can be contributed. The hot water tank 51 is manufactured from a material having heat resistance and corrosion resistance. The most desirable material is a metal such as stainless steel. However, the hot water tank 51 can also have a thermos structure, and in this case, glass can also be used as a material.

  The warm water tank 51 is connected with a middle / lower connection pipe 33, and drinking water is supplied from the pipe 33. A heating means is provided inside the hot water tank 51, and the drinking water is heated to warm water. This hot water is stored in a heated state until it is provided to the user. Accordingly, it is preferable that a constant temperature holding mechanism such as a thermistor is provided. As a heating means here, an underwater electric heater, an external tank heater, an infrared heater, an IH heater, an electromagnetic wave heater, or the like can be used.

  The hot water tank 51 is equipped with a hot water tank drain 59. Unlike the holding plate drains 23 and 43, the drain 59 is sealed when the cold / hot drinking water server 1 is used. However, the water remaining in the hot water tank 51 is removed by opening the drain 59 during cleaning and maintenance of the tank 51 and during transportation of the server 1.

  In FIG. 1, a tank / pump connection pipe 52 is connected to the lower part of the hot water tank 51, and a hot water pump 53 is connected to the pipe 52. However, the hot water pump 53 may be directly connected to the hot water tank 51. The hot water pump 53 is activated when hot water is provided, and pumps upward from the hot water tank 51. The hot water pump 53 may be installed above the hot water tank 51, or may be installed in the middle stage 30 or the upper stage 10. In the case of such a hot water pump 53 arrangement, the maintenance of the pump is easier than when the pump 53 is installed below the tank 51. However, as shown in FIG. 1, the hot water pumping efficiency is maximized by being installed immediately below the hot water tank 51. The type of the pump 53 is not limited, and for example, a vortex pump, a diffuser pump, a cascade pump, a vortex mixed flow pump, a diffuser mixed flow pump, a gear pump, and a diaphragm pump can be used.

In the cold water supply system, potable water is provided by flowing from the cold water bottle 11 to the cold water valve 12. In the hot water supply system, drinking water flows from the hot water bottle 31 to the hot water tank 51 via the hot water spout 32 and the middle / lower connection pipe 32, and is warmed and stored in the hot water tank 51. It is provided through a connection pipe 52, a hot water pump 53, a hot water spout pipe 54 and a hot water spout 55. Since these two systems are independent, cold water and hot water do not mix even if a reverse flow occurs. Therefore, waste of energy and cross contamination can be prevented.

  FIG. 2 is a side perspective view of the upper stage when the cold water bottle replacement door 21 is in the open state. In the open state of the replacement door 21, the front and upper sides of the cold water bottle 11 are opened, facilitating replacement of the bottle 11. Although the cold water bottle replacement door 21 in FIG. 2 has a two-stage structure, the replacement door 21 may be integrally formed. Moreover, an exchange door that opens only the front of the bottle 11 and an exchange door that opens only above the bottle 11 may be provided.

  FIG. 3 is a front perspective view of the cold / hot drinking water server 1. A warm water spouting button 25 is installed on the front surface. When the button 25 is pressed, the hot water pump 53 is activated and hot water is supplied from the hot water outlet 55. The button 25 is installed in the lower part of the upper stage 10 in FIG. Since this position substantially corresponds to the height of the chest of the user, the button 25 is easy to operate. A hot water discharge amount adjusting lever 26 is installed in the vicinity of the hot water discharge button 25. The lever 26 adjusts the amount of hot water discharged from the hot water outlet 55 by adjusting the operating speed of the hot water pump 53. Since the lever 26 is installed at the lower part of the upper stage 10 in FIG. 3, it is easy to operate.

  FIG. 4 is a top view of the cold and hot drinking water server 1 when the hot water water bottle replacement door 41 is in an open state. The replacement door 41 opens sideways and opens the front. Further, in order to open the upper side of the hot water bottle 31, it is necessary to provide a bottle 31 pull-out mechanism in the middle stage 30.

  FIG. 5 is a conceptual diagram showing a comparison between the effect of the conventional holding plate 122 and the effect of the holding plate of the present invention. In FIG. 5, an upper holding plate 22 is shown as an example of the holding plate of the present invention. FIG. 5A shows the effect of the conventional holding plate 122. The holding plate 122 is substantially horizontal. Therefore, when the cold water bottle 11 is a flexible water bag, the bottom surface of the bottle 11 is also substantially horizontal. When the cold water is provided, the cold water in the bottle 11 naturally flows out due to its own weight. However, when the water level falls to the vicinity of the height of the cold water valve 12, the remaining cold water can be discharged only by its own weight. This cold water is cold water that cannot be provided, and the capacity of this cold water is defined as dead volume. In FIG. 5A, since the holding plate 122 is horizontal, the dead volume is increased.

  FIG. 5B shows the effect of the upper holding plate 22 of the present invention. In FIG. 5B, the upper holding plate 22 is substantially horizontal and is further inclined forward. Due to this inclination, the water in the cold water bottle 11 gathers in the vicinity of the cold water valve 12, and as a result, the dead volume is reduced. Therefore, the amount of cold water that can be provided is larger than in the case of FIG. 5A, and the cold water bottle 11 can be used more efficiently.

  In FIG. 5, the upper stage holding plate 22 in the upper stage 10 is shown as an example, but it goes without saying that the concept presented in FIG. 5 can be applied to the middle stage holding plate 42 in the middle stage 30.
