  • This invention relates to water purification and sterilization systems and more particularly to a water sterilization system adapted for use with a bottled water dispenser that sterilizes the water by means of ultraviolet light.
  • Water dispenser appliances have long been used in homes and offices. In some parts of the world, they are very common for household use. Typically, they hold a supply bottle of two to five gallons in the USA and 15 to 25 liters in other countries.
  • the bottled water is typically purified, processed, or spring water supplied by a variety of vendors and large water bottling companies.
  • this type of drinking water is a good alternative to the use of tap water as it tastes better and may have most of the contaminants removed.
  • this type of water is quite pleasant and safe if the water is processed by a reputable company which includes a form of disinfection in its processing.
  • this tap water contains microbiological contaminants such as bacteria, fungi, and viruses, including microorganisms such as giardia and oocysts, among others.
  • the filter cartridge while often quite effective at removing many chemical contaminants, is mostly ineffective on microbes.
  • What is needed is a device and method to add disinfection treatment to these devices prior to dispensing the water.
  • Another problem comes from the improper processing of large bottled water by some companies. In some countries, typically third world countries, some vendors do not adequately process the water to make it biologically safe. Also, when this type of water is stored for long periods of time, bacterial, fungal, or viral levels may grow in the water bottle.
  • a further UV water cooler device uses a flow-through UV reactor which also includes a batch processing feature. This is a very complex and costly design.
  • the present invention includes a method and a device to disinfect water between a supply and a typical water dispenser.
  • the device includes an upper reservoir to hold water from the supply, typically a large bottle. As water is used in the reservoir of the dispenser, a float valve, a part of this device, allows water to gravity flow through this invention.

  • a mechanical filter may be used to remove this prior to or after the water has passed through the UV reactor 105.
  • the initial reservoir of the upper collar 104 is contemplated as providing sufficient pressure and/or gravity flow such that the water passes through the UV reactor 105 and on to the dispenser reservoir R (through the flow valve 106) and as providing a flow rate that ensures UV sterilization of the water passing through the UV reactor 105.
  • the rate of water flow may be calculated; and either the inlet and/or the outlet (122 in Figure 5; 135, 136 in Figure 6; and 148 in Figure 7) may be configured to ensure flow of the anticipated pressure. Generally, such pressure is regulated by gravity.
  • the configuration of the tubes 109, 110 and the UV reactor 105 are such that, should the dispenser reservoir R be empty, adding a new bottle of water at the upper collar 104 enables water flow through the UV reactor 105 through the float valve 106 and onto the dispenser reservoir R.
  • the reservoir 102 of the accessory 100 is generally controlled by the closing of the mouth of the bottle B by the rising water level in the enclosure 102. This is generally how water flow is controlled by dispensers; and the rising of the water level in the accessory reservoir 102 above the mouth of the bottle B prevents any further gas or air from entering into the bottle B which then in turn prevents the exit of water from the bottle B into the accessory reservoir 102.
  • the UV light may be left "on” at all times or, alternatively, may only be illuminated when water flows, as in by attachment to the valve through which the sterilized water flows to the consumer.
  • the latter option may be less attractive due to the energy requirements in turning on and turning off the lamp of the UV reactor 105 and which often may shorten lamp life. At relatively low energy levels, gaining a high degree of sterilization and so ultimately consume little energy may be possible.
  • Replacement of the UV lamp and the reactor 105 may generally be made once the bottle B has been removed as, for example, when it is empty. Alternatively, a full bottle may be removed taking care no water or as little as possible spills out of the bottle B.
  • the upper collar 104 may be removed from the enclosure 103 in order to obtain access to the UV reactor 105.
  • the power to the UV reactor may be turned off so that the UV bulb may be replaced.
  • the transmission of UV radiation from the UV reactor vessel 105 is entirely prevented so as to eliminate any injury that might occur due to the transmission of higher frequency UV light.
