Description

Steam sanitizer for water coolers
The present invention concerns an apparatus and method of cleaning fluid dispensing equipment. In particular, the invention concerns a thermal apparatus that can be used for cleaning and disinfecting fluid dispensing equipment such as spring-water coolers, seltzer-water dispensers and the like. A method for disinfection of such cooling equipment is also described in which use is made of the disinfection apparatus of the invention
Spring-water coolers, which are the primary application of the invention, should, in ordinary practice, be disinfected regularly, depending upon usage and load The disinfection must be undertaken in order to stop the growth of bacteria, algae and other matter in the drinking-water coolers This disinfection is practiced by all suppliers and distributors in Norway This work is demanding of resources and some particular methods of disinfection are environmentally unfriendly, additionally, all are costly
With the equipment and method of the invention, the work and consumption of resources are significantly reduced
Drinking-water coolers are found in enormous numbers all over the world. In Norway there are estimated to be approximately 20,000 units located in workshops, offices, reception rooms, stores etc and the number is growing. As mentioned above these coolers must be disinfected/cleaned at regular service intervals, often every three months
Drinking-water coolers are found in many variations, but most have drinking-water bottles placed on top of the cooler equipment itself The drinking water, which may be obtained from a natural spring, is supplied in standard plastic containers holding five gallons (approximately 19 liters) and these are placed upside-down on the drinking-water equipment. The containers have standard stoppers and closure means that prevent the water from running out when they are turned upside-down during container exchange. The drinking-water units have a small chiller tank that commonly has a volume of 2 liters and is equipped with a chiller unit. Some drinking-water coolers are additionally outfitted with a separate heating element and a separate tap for dispensing hot water. Drinking-water coolers are connected to the electrical network by the usual plugs. The methods currently used for disinfection or cleaning of drinking-water coolers are, as mentioned previously, very time-consuming and labor-intensive and can be divided into four main groups
Washing method:
Here the operator who is responsible for disinfection brings along a complete inner unit for the drinking-water cooler This inner unit has been cleaned previously in a washing machine that is approved for commercial kitchens This means that several components take up space and the taps must also be exchanged In addition the components have a tendency to become stuck during disassembly of the used equipment and installation of the clean components. In addition to being labor- intensive, the main disadvantage of this method is that the air intake cannot be cleaned in this way There is also considerable danger of contamination of the equipment during packaging, transportation and installation of the clean components
Chemical method:
In this method the operator removes the water container from the top of the cooler, empties out the water in the chiller tank and adds bactericidal chemicals to the equipment. These are allowed to operate for a while and then are rinsed out with pure water until the equipment is cleaned of chemicals Here again the air intake cannot be cleaned by this method. It is also difficult to know how much water is sufficient to remove all residue of bactericidal chemicals. Additionally, this method of cleaning cannot be considered to be consistent with the spring water, which is pure and natural in origin
Swap-out method.
Here the operator brings along a prefabricated unit produced under clean conditions This equipment is unpacked and exchanged with the existing equipment in the drinking-water cooler This method also involves the danger of contamination during assembly. The method is costly and may be characterized as an environmentally unfriendly use-and-discard principle since the used equipment is scrapped
Ionization method:
This method is carried out with the help of electrodes, but is little used The method requires special equipment, involves danger of radiation and is probably not very effective
The present invention is superior to the cleaning methods enumerated above, particularly in that the equipment and method of the invention clean efficiently in places that the known methods do not reach More specifically, the invention concerns an apparatus for use in cleaning and disinfecting fluid-dispensing equipment such as spring-water coolers, seltzer-water dispensers and others The apparatus consists of a housing with cover and gasket, a closure means, a heating element and a steam tube that extends from beneath the cover through the bottom of the housing
The invention also concerns a method for disinfecting fluid-dispensing equipment such as spring-water coolers and seltzer-water dispensers, wherein the disinfection apparatus is filled with water and applied to the top of the cooler unit, the steam tube being pressed down into the water supply, the disinfection apparatus being connected to power by means of in such a way that steam spreads around and through the supply pipe, the chiller chamber, airways and out through the taps
The equipment and the method of the invention involves no danger of contamination during or after the cleaning process, it is veiy economical of resources and it uses in neither bactericidal means, soap nor other chemicals In addition, the equipment is cheap to produce and is the size of an ordinary thermos bottle With respect to the method, after brief instruction is very simple to carry out a complete disinfection of a drinking-water cooler All of these advantageous aspects mean reduced costs as compared with the cleaning methods enumerated above
The invention will be more particularly explained with the help of drawings, where
Figure 1 shows the disinfection apparatus of the invention in a round and a rectangular embodiment
Figure 2 shows an overview of the equipment of the invention as seen from the
Figure 3 shows a section through the equipment
Figure 4 shows a section through the equipment as seen from above
Figure 1 shows a perspective drawing of the disinfection apparatus 10 of the invention in a round and an alternative rectangular embodiment Figure 2 shows the apparatus as seen from the side The apparatus 10 consists of a housing 3 that may be round or rectangular The housing 3 may be opened and closed with a cover 1 that is provided with a gasket 2 along its edge The cover is provided with a clip 8 that can close the cover securely A hinge 6 makes it possible to tilt the cover upward Figure 3 shows a cross-section of the disinfection apparatus from the side The steam tube 4 is mounted vertically and parallel with the walls of the housing The steam tube 4 extends from slightly below the cover 1 through the bottom 1 1 and downward The diameter of the steam tube 4 is somewhat larger than the opening of the intake tube in the top of the drinking-water cooler The housing 3 has a handle 9, preferably of a non-heat-conducting material
The housing 3 and the steam tube 4 are made of a sturdy material that can tolerate the heating and boiling of water, that is to say temperatures up to 100°C A suitable material may be stainless steel, but other metals, alloys or heat-resistant plastics may also come into consideration The cover 1 is also exposed to the same temperature and may be executed in heat-resistant plastic, another suitable material or combinations of different materials
Figure 4 shows the disinfection apparatus in cross-section from above Slightly above the bottom 1 1 of the house there is an element 5 for heating the water The heating element 5 has sufficient power to heat the water in the apparatus in 1 -3 minutes The element may be from 1500 W to 2400 W, preferably 1800 W to 2000 W for 230 V The element 5 has the shape of an ellipse in the figure, but may have another suitable coiled shape that facilitates rapid heating of the water The heating element 5 is connected to the electrical service via a connector 7 that has the same dimensions as that of the drinking-water equipment so that the same electrical cable can be used for the disinfection process In an alternative embodiment, the apparatus of the invention can be supplied with a charged battery as auxiliary equipment, which may be preferable in some situations
When it is desired to clean and disinfect a water cooler, the following method is used First, the water container is removed from the top of the water cooler unit The water container is provided with a standard stopper and closure such that splashing of water is avoided when the bottle is lifted Thereafter the cold-water tank in the cooler is emptied and the taps are locked in their open position The disinfection apparatus of the invention is filled with water, from approximately 0 5 to 1 liter and power is connected using the same connector as the cooler The steam tube from the disinfection apparatus is pressed down upon the intake tube of the cooler This is done in order that the intake tube may also be disinfected on its exterior surface The diameter of the steam tube is therefore somewhat greater than the diameter of the intake tube Because of the high wattage (approximately 2000 W), the water in the disinfection apparatus will boil in the course of 2 to 3 minutes This steam from the boiling water will first fill the housing and the steam tube and thereafter continue around and down through the intake tube into the cooler This steam continues further down into the chiller tank, into the tap tubing and out through the open taps The steam will also spread from the chiller tank out through the vertical air pipe and around the intake tube and stopper
Consideration must be given to the design and size of the drinking-water equipment when evaluating how long the disinfection should continue Experiments have shown that only 20 seconds steam exposure is sufficient to disinfect a water cooler unit of normal size In practice, one will allow the water in the disinfection apparatus to boil somewhat longer, and in any case long enough so that steam is seen emerging from the taps that form the lowest points to be disinfected Additionally, the temperature remains high on the parts that have been exposed to the steam The temperature within the chiller box has been measured as high as +98° to +99°C, and out through the taps it has been measured at +96°-97°C These temperatures are far above the requirements for +75° C set by the food preparation inspectors Experience shows that a minimum temperature of +75°C will remove all bacteria, but the highest possible temperature is desirable
After the water has boiled and the steam has spread for at least 20 seconds, power to the disinfection apparatus is turned off and it is removed from the drinking-water cooler Thereafter the drinking-water container is reinstalled and power is connected to the chiller unit Since the temperature in the chiller is high, it will take some time for the drinking water to become sufficiently chilled
The entire disinfection process thus takes less than 5 minutes
The disinfection apparatus of the invention may be provided with an over- eating sensor that ensures that the power is switched off if the heating element boils dry The apparatus may furthermore have an adjustable time-switch that provides an indication that the disinfection process is complete by means of a bell, sound or light signal
The apparatus and method thereby provide a much better and simpler disinfection than the methods currently used The high temperature of the steam will ensure a better result The use of soap or bactericidal chemicals is avoided, as is the danger that chemicals remain in the cooler after cleanin 'sg
As a consequence of these advantages, the apparatus and method of the invention wil reduce costs connected with the required disinfection
