Description

Field of technology

The utility model relates to bottled drinking water dispensers and, in particular, to dispensers with a system for treating water in the bottle with ultraviolet (UV) radiation.

Prior Art

It is known that to prevent biological contamination of water in a bottle installed in a dispenser, a source of UV radiation can be used, installing it in such a way that the UV radiation enters the bottle.

A device US 2016083271A1 is known for treating water in a container, for example a bottle, containing a housing and a UV radiation source located in the housing. The housing is releasably connected to an opening in the container to contact water in the container, and a light-emitting component is located on the housing and emits UV to irradiate the water in the container. However, such a device is intended for batch sterilization of water and the device must be removed from the container before filling the water.

A bottle dispenser JP 2017210256A is known, in which, to treat water in a bottle with UV radiation, it is proposed to use a UV LED placed at the end of the water intake finger. This solution causes difficulties when installing an inverted bottle on a dispenser. First, you must open the bottle before installing it, which may result in water spilling out when installing the bottle, as well as microorganisms entering the open bottle. Secondly, there is a danger of the LED being damaged by the neck of the bottle during installation, since it is quite difficult to accurately position a heavy bottle, which also blocks a person’s view of the connection point during the installation process.

The JP 3174477U bottle dispenser is known; in this dispenser, for treating water in a bottle with UV radiation, it is proposed to use semiconductor UV LEDs placed on the outer surface of the water intake finger. However, this solution is intended for soft (collapsing) bottles, and in the case of hard bottles it will not be effective, since the radiation of the LEDs located on the side surface of the water intake finger is directed, mainly horizontally, and the radiation will not be enough to effectively treat the water and air space in the upper part of the bottle . In addition, in this design, for effective treatment of water in a bottle, several LEDs are installed around the perimeter of the water intake finger.

The closest to the proposed technical solution is the dispenser described in WO 2016157124A1. In this dispenser, for treating water in a bottle with UV radiation, it is proposed to use a UV lamp placed inside a water intake finger made of a material transparent to UV radiation. When installing the bottle in the dispenser, the water intake finger uncorks the cap and goes inside the bottle. However, this solution has a number of disadvantages.

Since UV radiation enters the bottle through the side walls of the water intake pin and is directed mainly horizontally, for effective treatment of water in the bottle it is necessary to increase the length of the water intake pin, which reduces its strength and causes difficulties with installing the bottle in the dispenser. And even this may not be enough to effectively treat the water and air space at the top of the bottle.

At the same time, known plastic materials have a fairly low transmittance of UV radiation, which requires increasing the power of the UV source. And if you use quartz glass, which has a higher transmittance, then the water intake finger turns out to be more expensive and, most importantly, more fragile and therefore dangerous to use if it is damaged.

Moreover, the use of a UV lamp in the water intake finger is a source of increased danger, since when installing a heavy bottle, damage to the water intake finger and, as a result, the llama is possible, while the mercury vapor contained in the lamp, which is very dangerous to health, will enter the water and if this If left unnoticed, they can cause serious harm to human health.

In addition, placing a lamp in the water intake finger significantly reduces its throughput, since the lamp occupies most of the internal space of the finger.

For such a dispenser, in which a lamp is installed inside the water intake pin, a special stopper is required with a lower force required to uncork it compared to a standard stopper. Therefore, such a dispenser is not suitable for use with widespread PET bottles closed with Save Guard (tm) caps and similar ones.

This bottle, usually three or five gallons (11 or 19 liters) in size, is made of rigid plastic and, unlike so-called collapsible bottles, retains its shape when water is poured out. Such a bottle has a neck with an outer diameter of about 6 centimeters and is usually closed with a stopper, in the middle part of which there is an internal hole with a diameter of about 18 millimeters, which is closed either by a valve pushed into the bottle or by a ruptured valve. When installing such a bottle in a dispenser, the bottle is placed on a water intake finger, which uncorks the bottle by squeezing the valve inside the bottle or breaking it, depending on the type of stopper.

When uncorking such a bottle, the water intake finger presses its end onto the valve or partition with a force of 10 to 30 kilograms (100-300 N). Given that the outer diameter of the intake pin corresponds to the internal opening of the stopper (approximately 18 millimeters), the intake pin for this type of bottle is usually made of a durable plastic such as ABS.

Essence of a utility model

The technical result of the utility model is to increase the reliability of the dispenser, to ensure effective treatment of water in a bottle installed in the dispenser using a UV radiation source placed in the bottle when it is installed in the dispenser, and to ensure automatic uncorking of the bottle when it is installed in the dispenser. Automatic uncorking of the bottle at the time of its installation in the dispenser serves to prevent microbiological contamination from entering the water in the bottle at the time of its installation on the dispenser.

The technical result is achieved due to the fact that a bottled drinking water dispenser with a system for treating water in the bottle with UV radiation contains a water intake finger equipped with a source of UV radiation, and is configured to uncork the bottle either by tearing or by pushing a valve installed inside the bottle in the center of the plug, while a semiconductor LED is used as a source of UV radiation, installed in a recess made at the end of the water intake finger, and protected on top by quartz glass covering the recess.

The dispenser may additionally contain a frame structure attached to the end of the water intake pin. This frame design makes it easier to uncork a break-flap cap, which can be useful if the cap is made of a thicker plastic.

The frame structure can be made in the form of rods forming a pyramid, the top of which is located on the axis of the water intake pin, above its end surface. Moreover, the number of rods forming a pyramid is at least three. This frame structure is strong enough to rupture the plug valve, but does not greatly obscure the UV source.

The upper part of the water intake finger can be made of metal. Making the upper part of the water intake pin from metal not only increases its strength, but also improves heat removal from the UV source.

Preferably, the quartz glass is installed in a recess below the top surface of the intake pin. Thus, quartz glass is better protected from damage or accidental scratches.

In some implementations, the dispenser further includes a water intake tube, and the water intake finger is provided with a channel configured so that through this channel the end of the water intake tube can pass into the bottle, and the length of the water intake tube is sufficient for the end of the water intake tube to reach the bottom of the bottle.

First implementation

Figure 1 shows the appearance, and Fig. 2 internal structure of a bottled drinking water dispenser. This dispenser is designed to use 3 or 5 gallon (11 or 19 liter) bottles. Dispenser 1 contains a body 2, in the upper part of which there is a bottle receptacle 3 for installing an inverted bottle 4. In the center of the bottle receptacle 3 there is a water intake finger 5, which, when installing the bottle 4 in the dispenser 1, uncorks the bottle 4, breaking or pushing the stopper valve 6 inside the bottle 4 When installing a new bottle 4 into the dispenser 1, the bottle 4 is turned over and installed with the neck down in the bottle receptacle 3. In this case, when installing the bottle 4, the stopper 6 of the bottle 4 rests on the water intake pin 5, which breaks or pushes the valve located in the center of the stopper 6 inside bottles 4.

The water intake finger 5 is connected to an internal storage tank 8, equipped with a cooling device 9. The internal storage tank 8 has two outlets 10, 11, one for cold water 10, and the other for water at room temperature 11. An outlet for cold water 10 and an outlet for room temperature water temperature 11 through solenoid valves 12 are connected to the common output 13 of the dispenser for dispensing water. The outlet for room temperature water 11 is also connected to a hot water tank 14 equipped with a heating device 15. The hot water tank 14 is connected through a solenoid valve 12 to the common output 15 of the dispenser 1.

To maintain the purity of water in the dispenser 1, several additional sources of UV radiation 16 are installed inside the storage tank 8. Sources of UV radiation 16 inside the storage tank 8 serve to maintain the microbiological purity of the water inside the tank 8. As sources of UV radiation 16 inside the storage tank 8 UV-C semiconductor LEDs are used. Periodic inclusion of these sources 16 helps maintain the microbiological purity of water inside the storage tank 8. Since the storage tank 8 always contains a certain number of microorganisms that get there from the surrounding air, and possibly from water in bottles, without periodic treatment of the water in tank 8 UV radiation, the number of microorganisms may exceed the permissible values for drinking water.

Also in the housing 2 there is a control device 35 and a power source 36 to ensure the operation of the dispenser 1.

Figure 3 shows the water intake pin 5 in section. The water intake finger 5 is located in the central part of the bottle receptacle 3. The water intake finger 5 has two internal channels, an air channel 17 through which air from the dispenser 1 enters the bottle 4, and a water channel 18 through which water from the bottle 4 enters the dispenser 1. At the top part of the water intake finger 5 there are two holes, a water hole 19 and an air hole 20. At the bottom of the water intake finger 5 there is an outlet for water 21 from the water channel 18 and an air inlet 22 into the air channel 17.

A UV radiation source 25 is installed at the end of the water intake pin 5. The UV radiation source 25 is installed in a recess 24 made at the end of the water intake pin 5. The UV radiation source 25 is a semiconductor UV LED, which is installed on the board 26. Power supply to the UV radiation source 25 is carried out via wires 27, which pass through a tunnel 28 made inside the water intake finger 5. The recess 24, in which the UV radiation source 25 is located, is closed on top with quartz glass 29. Using the UV radiation source 25, processing takes place water and air inside the bottle with UV radiation. Since the maximum increase in the number of microbiological contamination occurs on the walls of the bottle and at the boundary of the water-air space of the bottle, the radiation of the source 25 is directed upward, towards the water surface and towards the walls of the bottle.

It is known that microbiological contamination in water in a drinking water bottle tends to increase after opening the bottle. It has been verified that in initially microbiologically pure water, 14 days after uncorking the bottle, the level of microbiological contamination in the bottle can exceed one hundred thousand KOE/ml (Colony-forming units per milliliter). With sanitary standards for drinking water no more than 1000 CFU/ml.

As an example, Figure 4 shows the results of measuring microbiological contamination in an open bottle, without using UV radiation to suppress the development of microbiological contamination. The X axis shows the days after opening the bottle, the Y axis shows the level of microbiological contamination in CFU/ml. It can be seen that already a week after the bottle was opened, the level of microbiological contamination may exceed permissible sanitary standards.

As you know, ultraviolet radiation is electromagnetic radiation with wavelengths just below the visible light spectrum (400-780 nm). UV radiation is divided into three groups: UV-A with a wavelength of 315-400 nm, UV-B with a wavelength of 280-315 nm and UV-C with a wavelength of 200-280 nm. Along with its visible spectrum, the sun also emits ultraviolet light. However, unlike UV-A and UV-B rays, the UV-C fraction is almost completely absorbed by the earth's atmosphere. This is why microorganisms have not had the opportunity to develop proper resistance mechanisms to UV-C. Therefore, the most effective part of UV radiation for killing these organisms is UV-C, with an inactivation peak at 254 nm. Damage to microorganisms caused by UV-C radiation occurs directly at the DNA level. UV-C irradiation of the DNA molecule causes the thymine bases to form holes. Thus, the enzymes responsible for unwinding and copying DNA during replication are no longer able to function. This makes the microorganism unable to reproduce and cause infection. Thus, UV-C radiation has a bacteriostatic effect, and not a primarily bactericidal one. All waterborne enteric pathogens can be inactivated by ultraviolet light if given a sufficient dose. Different microorganisms exhibit different sensitivity to UV-C radiation.

Experimentally, it was found that for a sustainable reduction in microbiological contamination of water in a 19-liter bottle, it is enough to periodically treat the water and the source of UV radiation can be of relatively low power.

In FIG. Figure 5 shows the results of changes in microbiological contamination of water when the UV radiation source is turned on once an hour for ten minutes, and with an optical power of the source of 30 mW at an average radiation frequency of 270 nm. Thus, the relatively weak radiation of a UV radiation source placed in a water bottle can significantly reduce the possibility of microbiological contamination of water in the dispenser and the danger of dispensing contaminated water to the consumer.

The dispenser works as follows. When installing a new full bottle 4, the bottle 4 is turned upside down and lowered into the bottle receptacle 3, so that the neck of the bottle 4 is put on the water intake finger 5. In this case, the water intake finger 5 first rests against the valve 7 of the plug 6, and then, with further lowering of the bottle 4, uncorks the bottle by breaking or pushing the valve 7 inside the bottle 4. After the water intake finger 6 has entered the bottle 4, water from the bottle 4 begins to flow into the dispenser 1 through the water channel 18 of the water intake finger 5, and air from the dispenser 1, through the air channel of the water intake finger 17 enters the bottle 4, replacing the water flowing out of the bottle 4.

In order to place the UV radiation source 25 inside the bottle 4, the source 25 is installed on the upper end surface of the water intake finger 5. Thus, when the bottle 4 is uncorked with the water intake finger 5, the source 25 appears inside the bottle 4. In order not to damage the UV source radiation 25 when the bottle 4 is uncorked, the source is installed in recess 24 and covered with quartz glass 29.

When the internal storage tank 8 is filled with water, the water closes the air inlet 22 of the air channel 17, and since air no longer enters the bottle 4, the flow of water from the bottle 4 stops. When dispensing water from the dispenser 1, the water level in the storage tank 8 decreases, thereby opening air access to bottle 4, and water begins to flow from bottle 4 into dispenser 1 until the rising water level again blocks the air supply to bottle 4.

During operation of the dispenser, the control device 35 turns on the UV radiation source 25 installed in the water intake finger 5 at a given frequency to prevent the development of microbiological contamination of the water in the bottle. The control device 35 also controls the operation of additional sources of UV radiation 16 installed in the storage tank 8 to prevent the development of microbiological contamination in it.

The presence of 8 additional sources of UV radiation 16 in the storage tank helps to improve the microbiological condition of the dispenser, however, additional sources of UV radiation 16 inside the dispenser cannot replace the source of UV radiation 25 in the bottle. Firstly, because the more contaminated the water entering the dispenser is, the more powerful UV radiation is required to treat the water inside the dispenser. Therefore, if water contamination in the bottle increases, for example, during a long break in the operation of the dispenser, which can reach a month or even more, the installed power of the UV sources inside the dispenser may not be enough for reliable water treatment. And, secondly, when dispensing water to the consumer, the water dispensed from the dispenser is replaced by water from the bottle. In this case, due to the mixing of water from the bottle with water inside the dispenser, some part of the microbiologically contaminated water from the bottle can immediately reach the consumer, bypassing the treatment with UV radiation inside the storage tank 8. Especially when dispensing water at room temperature to the consumer, since water at room temperature is taken from the top layer of water in the storage tank 8, and water from the bottle also enters the top layer of water in the storage tank 8.

Such a water intake finger 5, as shown in Fig. 3, can uncork stoppers with either a push-in valve or a burst valve. Examples of such plugs are shown in Fig. 12 a and b. When uncorking the cap 6 with valve 7 pushed inside the bottle, Fig. 12a, the extreme edge of the water intake pin 5 rests against the edge of the valve 7, pushing it inside the bottle 4. And when uncorking the cap with the burst valve Fig. 12b, the upper part of the water intake pin 5 rests into the burst valve and ruptures it.

Figure 6 shows an embodiment of a water intake finger. The water intake finger 5, in comparison with the water intake finger 5 shown in Figure 3, additionally contains a frame structure 31 attached to the end of the water intake finger 5. The frame structure 31 is made in the form of four rods 32 forming a pyramid, the top of which is located on the axis of the water intake finger 5, above its end surface. The frame structure 31 facilitates the uncorking of the bottle 4 with a stopper 6 containing a burst valve. When uncorking, the pointed end of the frame structure rests against the center of the valve, and since the force is applied to the tip, the area of which is significantly less than the area of the end surface of the finger, the tip easily breaks the valve of the plug 6.

In order for such a water intake finger 5 to be able to open plugs 6 with a push-out valve 7, the height of the frame structure 31 is made less than the depth of the valve 7. Therefore, when opening such plugs, the water intake finger 5 rests against the valve 7 with the edge of the end surface and pushes it inside the bottle. In this case, the top of the pyramid or the pointed end of the frame structure does not reach the bottom of valve 7 and does not participate in uncorking the bottle. Since the frame structure 31 is made of relatively thin rods with an open space between them, it does not interfere with UV radiation from the source 25 located below it.

Figure 7 shows another version of the water intake finger. The main difference between this option and that shown in Figure 2 and Figure 3 is that the main part of the water intake finger 5 is made, as in previous versions, of plastic, and the upper part 34 is made of metal, for example, stainless steel. Making the upper part 34 of the water intake pin made of metal, on the one hand, increases the strength of that part of the water intake pin, which bears the main load when uncorking the bottle, and on the other hand, improves heat removal from the source of UV radiation.

Second implementation

Figure 8 shows a desktop version of the dispenser. Dispenser 1 contains a body 2, in the upper part of which there is a bottle receptacle 3 for installing an inverted bottle 4. In the center of the bottle receptacle 3 there is a water intake finger 5, which, when installing the bottle 4 in the dispenser 1, uncorks the bottle 4, pushing the stopper valve 6 inside the bottle 4. B Unlike dispenser 1, this dispenser 1 is designed to dispense only water at room temperature and does not contain an internal storage tank. The water intake finger 5 is connected to the outlet valve 41 by pipeline 42. Air enters the bottle 4 through the air channel 17 of the water intake finger, connected to the air filter and equipped with a check valve.

At the end of the water intake finger 5 there is a UV radiation source 25, which is connected to a control device (not shown) and a power source (not shown) installed in the housing 2. The control device ensures periodic activation of the UV source to maintain the microbiological purity of water in bottle 4.B With this design, the presence of a source of UV radiation in the bottle is especially useful, since water from the bottle is immediately supplied to the consumer and is not subject to additional treatment with UV radiation inside the dispenser. Otherwise, the design of the water intake finger 5 with the UV radiation source 25 does not differ from the water intake finger 5 in the first embodiment of the dispenser shown in Fig. 3.

Third implementation

Figure 9 shows another possible implementation of the dispenser. In this implementation, the dispenser 1 consists of a fastening 46 connected together, put on the neck of the bottle 4, a water intake finger 5, and an outlet valve 41 connected to the water intake finger 5. The dispenser 1 is fixed directly on the neck of the bottle 4, which is installed with the neck down, at an angle of approximately 1 degrees from the vertical on the stand 49. In this implementation, the dispenser 1 is first placed on the neck of the bottle 4, with the neck facing up, while the water intake finger 5 uncorks the bottle 4, pushing or punching the valve plug 6. After installing the dispenser 1 on the neck of the bottle 4, the bottle 4 is turned over and installed on the stand 49. The stand 49 also contains a control device not shown and a power source not shown to ensure the operation of the UV radiation source 25 installed at the end of the water intake finger 5. After installing the bottle 4 on the stand, the dispenser 1 is connected to the stand electric cable 51. Otherwise, the design and operation of the dispenser 1 are similar to the dispenser shown in Fig. 8.

Fourth implementation

Figure 10 shows another possible implementation of the dispenser. The main difference between the dispenser 1 shown in Fig. 10 and the dispenser 1 shown in Fig. 2 is that the bottle 4 is located in the lower part of the body 2 in the neck-up position. In this configuration, water from the bottle 4 is supplied to the storage tank 8 using a water pump 58, which is connected to the storage tank 8 by a pipeline 42. Otherwise, the design of the dispenser 1 is similar to that of the dispenser in FIG. 2. The internal storage tank 8, equipped with a cooling device 9, has an outlet for cold water 10, and an outlet for room temperature water 11. The outlet for cold water 10 and the outlet for room temperature water 11 are connected through solenoid valves 12, 12 to a common outlet 13 for dispensing water. The outlet for room temperature water 11 is also connected to a hot water tank 14, equipped with a heating device 15. The hot water tank 14 is connected through a solenoid valve 12 to the common output 13 of the dispenser 1.

Also in the housing 2 there is a control device 35 and a power source 36 to ensure the operation of the dispenser 1.

The design of the water intake finger 5 is shown in Fig. 11. Since, when the bottle 4 is positioned with the neck up, the water intake pin 5 is above the water level in the bottle 4, the dispenser is additionally equipped with a water intake tube 71, which, after uncorking the bottle 4 with the water intake pin 5, is inserted into the bottle 4 through a channel made in the water intake pin 5 72. The water intake tube 71 is of sufficient length to reach the bottom of the bottle 4. The water intake tube 71 is connected to the pump 58 using a flexible pipeline 73.

To prevent the development of microbiological contamination in the bottle after it is uncorked, a UV source 25 is installed at the end of the water intake finger 5. The UV radiation source 25 is installed in a recess 24 made in the end of the water intake finger 5. The UV radiation source 25 is a semiconductor LED mounted on board 26. The recess 24, in which the UV radiation source 25 is located, is covered with quartz glass 29. The power supply to the UV radiation source 25 is carried out through wires 27, which pass through a tunnel 28 made inside the water intake pin 5.

To maintain the purity of the water inside the dispenser, several sources of UV radiation 16 are also installed in the storage tank 8. Sources of UV radiation 16 inside the storage tank 8 serve to maintain the microbiological purity of the water inside the tank 8.

When installing a new bottle 4 into the dispenser 1, first, using the water intake pin 5, uncork the bottle 4, pushing the water intake pin 5 through the stopper 6, then the water intake pin 5 is secured to the neck of the bottle 4, for example, using a flange 74. After this, through channel 72 water intake finger 5 passes the water intake tube 71 and connects the water intake tube 71 with a flexible pipeline 73 to the pump 58.

Fifth implementation

Figure 13 shows another possible implementation of the dispenser. In this implementation, the dispenser 1 consists of a storage tank 8 equipped with an outlet tap 41, a bottle receptacle 3 installed in the upper part of the storage tank 8, and a water intake pin 5 installed in the center of the funnel of the bottle receptacle 3.

The water intake finger 5 has two internal channels, an air channel 17 through which air from the dispenser 1 enters the bottle 4, and a water channel 18 through which water from the bottle 4 enters the dispenser 1.

To clean the outside air entering the dispenser, dispenser 1 is equipped with an air filter 94.

A UV radiation source 25 is installed in a recess made at the end of the water intake finger 5. At the top, the recess in which the UV radiation source 25 is installed is covered with quartz glass. The UV radiation source 25 is connected to an external control device and a power source. The control device ensures periodic activation of the UV 25 source to maintain the microbiological purity of water in bottle 4.

To maintain the microbiological purity of water in the storage tank 8, several additional sources of UV radiation 16 are installed in it. Additional sources of UV radiation 16 are also connected to the control device and power supply.

Thus, the proposed utility model makes it possible to place a source of UV radiation in a bottled drinking water dispenser in such a way as to effectively process water and air space in the bottle, and at the same time maintain the function of automatically uncorking the bottle using a water intake finger when installing the bottle in the dispenser.
