Water is discharged while the generated water is stopped and the flow rate is adjusted.

  A pipe-shaped water discharge portion 39 for discharging generated water is integrally suspended from the lower surface side of the water intake valve 36, and a silicon hose 40 is attached to the water discharge portion 39. When the water surface of the mineral water M (product water) in the water storage cassette 20 is lowered and the generated water is discharged from the water discharge part 39 of the water inlet valve 36, the lower end of the water discharge part 39 is positioned above the water surface of the mineral water M. When the water is discharged, the generated water drops and foams vigorously. In addition, when the water is discharged from the water discharge portion 39, the generated water may come into contact with the air in the casing 31 or may come into contact with the air in the case of foaming as described above.

Therefore, when the generated water is discharged from the water discharge portion 39 of the water intake valve 36, the hose 40 is connected to the water discharge portion 39 in order to prevent more direct contact with the air by foaming. Is soaked in mineral water M in the casing 31. As a result, the generated water replenished from the water inlet valve 36 into the water storage cassette 20 is not bubbled into contact with the air, so that residual chlorine injected by contact with the air can be prevented from being vaporized and consumed. The safety of the mineral water M in the cassette 20 can be improved.
Further, a chlorine dropping water inlet 43 into which diluted chlorine from the chlorine injector 18 is injected is provided at the upper part of the water inlet valve 36 located outside the casing 31.

A filter device 44 is mounted on the bottom of the casing 31 of the water storage cassette 20, and this filter device 44 includes a mesh-like square box 45 having an outer shell made of stainless steel, and an inside of the box 45.

The other linear body 51 is long and the lower end of the linear body 51 reaches the vicinity of the filter device 44, and a water level sensor 52 for detecting the water level of the mineral water M is provided at the lower end. .

When the capacity of the mineral water M stored in the water storage cassette 20 is, for example, 12 liters and the state shown in FIG. 4 is full, the water level sensor 50 is positioned above the surface of the mineral water M. While the float 38 of the water inlet valve 36 stops the mineral water at the position shown in the figure, if for some reason the mineral water continues to flow out of the water inlet valve 36 and the mineral water level rises. The water level sensor 50 detects this and turns off the electromagnetic valve 19 interposed in the front stage of the water storage cassette 20 to stop the water entering the water storage cassette 20.
Note that an air hole 53 having a function of a drain hole is formed in the upper portion of the casing 31. However, when the sensor system using the water level sensors 50 and 52 instead of the float-type water intake valve 36 is used, the air hole 53 is used as a drainage hole and connected to a drainage pan with a pipe and overflowed. It is good also as a structure which draws in water.

Further, when the mineral water M in the water storage cassette 20 continues to flow out and the amount of water decreases and the water level sensor 52 detects the surface of the mineral water M that has decreased, the pressurization pump 21 stops driving and the pressurization pump 21 and the subsequent steps. The water is stopped.
On the lower surface of the casing 31 is provided a water discharge valve 54 for discharging the mineral water M in the water storage cassette 20 to the pressure pump 21 side, and the mineral water M is sent to the pressure pump 21 side through the water discharge valve 54. Be paid.

  As shown in FIG. 6, the lid 33 of the water storage cassette 20 has one hole 55 through which the two linear bodies 49 and 51 of the sensor main body 47 and the three ground bars 66 are inserted. ing. Further, the filter device 44 is provided with a hand-held portion 56 for facilitating the insertion and removal of the filter device 44 into and from the casing 31.

Thus, since the water storage cassette 20 is a cassette type that is detachable from the mineral water vending apparatus 1, for example, the water storage cassette 20 is periodically taken out from the mineral water vending apparatus 1 to clean the inside. Thus, it is possible to prevent the propagation of germs in the mineral water M in the water storage cassette 20 and to provide the mineral water M with further improved safety. Moreover, it can replace | exchange for the new water storage cassette 20 regularly, and can provide the safer mineral water M.
In addition, in the case of an elevated water tank in a building, contamination of germs in the water storage tank is unavoidable, and it is safe to drink as drinking water because minerals are regularly washed in the water tank and chlorine is dripped again. It is expected that the accumulated water stored in the water storage cassette 20 of the mineral water M in the water vending apparatus 1 will be unsuitable for drinking due to propagation of various bacteria. However, in the present invention, chlorine is dripped by the chlorine injecting device 18 and can be easily replaced with a new water storage cassette 20 periodically, so that the mineral water M in the water storage cassette 20 is inappropriate for drinking. As shown in FIG. 3, the residual chlorine in the water storage cassette 20 can be easily measured by draining the drainage port 67 through the drainage valve 67 that can drain directly from the pressurizing pump 21. Can do.

Next, the control operation in which the mineral water M is poured in the mineral water vending apparatus 1 will be described. First, as shown in FIG. 3, the mineral water vending apparatus 1 is directly connected to a public water supply, and the generated water is sent to the water purifier 15, the water heater 17, and the water storage cassette 20 by the water pressure. In the water purifier 15, chlorine, organic matter, trihalomethane, etc. contained in the tap water W are removed.
The generated water exiting the water purifier 15 is injected with carbon dioxide gas from a carbon dioxide cylinder 16 and fed to the active water device 17 where the generated water comes into contact with ore such as granular barley stone and elutes mineral components and the like. At the same time, elution of mineral components is promoted by carbon dioxide gas, and mineral water M is generated.

  When being supplied from the water heater 17 to the water storage cassette 20, the chlorine diluted by the chlorine injection device 18 is injected, and the mineral water M in the water storage cassette 20 is adjusted to a chlorine concentration of 0.16 ppm, for example. ing. By the injection of chlorine, the mineral water M in the water storage cassette 20 is sterilized, and the water storage cassette 20 is provided with a filter device 44 composed of ore 46 such as barleystone, and the mineral in the water storage cassette 20 is provided.

Is unlocked. The amount of drainage at this time is 100 cc, for example, and the flow rate sensor 23a (23b) measures this flow rate, and the control unit 62 receives the signal from the flow rate sensor 23a (23b) and controls the electromagnetic valve 27a (27b) to be closed. To do.

Next, the user opens the door 4, sets the container 2 below the cleaning port 5, closes the door 4, and presses the cleaning switch 8 (see FIGS. 1 and 7). When the washing switch 8 is pushed, a signal from the washing switch 8 is input to the control unit 62, and the control unit 62 uses the signal from the flow sensor 23a (23b) to discharge 600 cc of mineral water M from the electromagnetic valve. 26a (26b) is controlled to open. The amount of 600 cc of the mineral water M is measured by the flow rate sensor 23a (23b), and the measurement signal is sent to the control unit 62.
At the same time, the controller 62 controls to open the electromagnetic valve 28a (28b), and 200 cc of tap water W from the public water supply is discharged from the cleaning port 5a (5b) through the electromagnetic valve 28a (28b). The amount of the 200 cc tap water W is controlled by the opening time of the electromagnetic valve 28a (28b).

In this way, when the washing switch 8 is pushed, the tap water W containing 600 cc of mineral water M and 200 cc of chlorine from the public water supply is injected into the container 2 from the washing port 5a (5b). The user manually cleans the container 2 with about 800 cc of water. After washing the container 2, the washing water is drained, and the container 2 is set below the water inlet 6a (6b).
When the container 2 is set, a sensor (not shown) is detected, and a button for displaying a desired water amount is lit. When the button is pressed, the control unit 62 opens the electromagnetic valve 27a (27b) to control the mineral water M. It is injected into the container 2 through the water injection port 6a (6b). The injection amount into the container 2 at this time is, for example, 2 liters.

Further, when the mineral water M is discharged from the water injection port 6a (6b), a small amount of chlorine having a chlorine concentration of 80 ppm is injected from the chlorine injection device 24a (24b) into the water injection port 6a (6b). As a result, even if the chlorine concentration of the mineral water M discharged into the container 2 is 0.08 ppm and the user takes it home and puts it for about a week, for example, the mineral in the container 2 Miscellaneous bacteria are prevented from breeding in the water M.
Moreover, even if miscellaneous bacteria propagate in the container 2, the amount thereof is set to be equal to or less than the numerical value stipulated by the law.

The amount of 2 liters is measured by the flow rate sensor 23a (23b), and when 2 liters are measured, a signal is sent from the flow rate sensor 23a (23b) to the control unit 62, and the control unit 62 transmits the electromagnetic valve 27a ( 27b) is closed.
When 2 liters of mineral water M is discharged into the container 2, the user opens the door 4 and takes out the container 2.

  Here, since the storage amount of the mineral water M in the water storage cassette 20 is 12 liters, even if two users discharge 2 liters of mineral water M at the same time, the amount of water discharge does not decrease. . Moreover, the washing time of the container 2 and the water injection time of the mineral water M to the container 2 are 2 to 3 minutes per container 2, and even if two users continuously discharge the mineral water M simultaneously. The water storage cassette 20 does not stop the discharge of the mineral water M, and the amount of water discharged per minute does not decrease.

The mineral water M in the water storage cassette 20 is replenished by a float-type water intake valve 36 using a float 38 so as to always have a storage amount of 12 liters. Thereby, even if the mineral water M is continuously discharged from the water inlet 6 at regular intervals, the mineral water M from the mineral water generating means 17 is replenished in the water storage cassette 20 according to this water discharge, and the mineral water Even if M flows out continuously, a decrease in the amount of water discharged per minute of the mineral water M can be prevented.
That is, when a large number of users use mineral water M and the amount of mineral water M in the water storage cassette 20 decreases, the water is stored between the waiting time of the user and the operation time at the time of flooding. A predetermined amount of water can be safely stored in the cassette 20 and can cope with a decrease in the amount of water discharged.

  In addition, as shown in FIG. 3, although the water supply path | route after the pressurization pump 21 is made into 2, the capacity | capacitance of the pressurization pump 21 and the storage capacity | capacitance of the water storage cassette 20 are enlarged appropriately, and three water supply paths are provided. It is good also as above.

Thus, in the prior art, since the water supply route is one and water is supplied one by one, the waiting time may be one hour or longer, but the water storage cassette 20 and the pressure pump 21 are provided, and 2 Two water can be supplied simultaneously by the mouth water supply (two water inlets 6a and 6b), and the waiting time can be reduced to half. In addition, until now, it was necessary to connect the same water purifier in parallel to make up for the shortage of water due to clogging of the water purifier filter, and always ensure a certain amount of mineral water M. The water storage cassette 20 in the apparatus 1 can always be replenished at the customer waiting time, the water purifier can be used to the full, and the running cost can be reduced.
In particular, even if a large number of users continuously discharge the mineral water M at regular time intervals, the mineral water M can be discharged without reducing the amount of water discharged per minute, and the user is not uncomfortable.

  That is, since the water discharge path is separated into two from the pressurizing pump 21 and two water injection ports 6 are provided, coupled with the provision of the water storage cassette 20 and the pressurizing pump 21 capable of discharging a constant water pressure and a constant amount of water. At the same time, the mineral water M can be discharged from the two water inlets 6, so that the waiting time can be greatly shortened. Further, even if the water purifier 15 and the water purifier 17 are clogged to some extent and the amount of the mineral water M discharged is reduced, the mineral water can be kept in the waiting time for the user's operation time and the time for capping the container 2 with the cap. Can be stored in the water storage cassette 20, so that these members can be used to the fullest and the running cost can be reduced.

Further, as a means for adjusting the amount of water in the water storage cassette 20 to be constant, in the previous embodiment, both the water inlet valve 36 and the sensor main body 47 were used as the replenishment control means, but only at least one of them is used. May be used.
For example, when the amount of water in the water storage cassette 20 is adjusted using only the sensor main body 47, the water inlet valve 36 is a valve that does not have a valve mechanism, and the valve can be easily detached from the water storage cassette 20. To do. Further, the tip of the water discharge hose 40 connected to this valve is immersed in the generated water in the water storage cassette 20 as in the previous embodiment. The air holes 53 are used as drain holes.

  In the previous embodiment, the two-port water supply is provided with the water storage cassette 20 and the pressure pump 21, but even in the case of one-port water supply, by using the water storage cassette 20 and the pressure pump 21, Even in the case of continuous water supply of mineral water M, a decrease in the amount of water discharged per minute due to clogging of the sterilizer 22a (22b) can be prevented, and the user is not uncomfortable.
