Description
Technical field
The present invention relates to the water dispenser technical field, refer in particular to a kind of circulating repurifying type drinking machine with prevention of secondary pollution.
Background technology
Water dispenser secondary pollution problem, be meant that the drink water after barreled drink water or special water purifier for drinking machine purify flows through from the water circuit system of water dispenser, flow out from the water fountain effluent valve again, its water quality index is on a declining curve, show that mainly water turbidity rises, the bacterial population in the water increases.The nearly all water dispenser of this problem is ubiquity all.Its reason is:
1, the water in the water dispenser bucket directly communicates with extraneous air, and dust in air, bacterium directly enter in the water, produces secondary pollution;
2, the water in the water dispenser is may the holding time long, grow microorganism, and water dispenser itself does not have sterilization, bacteria resistance function or sterilization, bacteria resistance function not to meet the demands.
At this problem, more existing patented technology schemes.
The first kind is a pharmaceutical methods, and the sterilization nonwoven for example is set before the water fountain effluent valve, perhaps puts into sterilization or antibacterial material etc. in the water dispenser bucket.These methods have certain effect to preventing out water generates microbial contamination, but reliability is not high, because these active ingredients antibacterial or sterilization material can be separated out in water gradually, concentration can be more and more lower, and its sterilization or fungistatic effect fade away.
Second class is a filter method, and the ultrafiltration membrance filter bacterium for example is set before the water fountain effluent valve.In order to overcome the flow resistance of milipore filter, water pump is set on pipeline also.This method bacteria-eliminating efficacy is fine, and just the water fountain effluent flow is influenced by the water flow of milipore filter, for bigger water flow is arranged, and the milipore filter that the user must often more renew, this causes use cost higher.
The 3rd class is the ultraviolet sterilization method, for example before the water fountain effluent valve apparatus for ultraviolet disinfection is set, and perhaps in cold jar of water dispenser ultraviolet lamp is set.It is generally acknowledged that ultraviolet ray sterilization coverage in water is not more than 20 millimeters, carry out effective sterilizing, more can not carry out disinfection water in the bucket and the water in the pipeline so be located at the water that ultraviolet lamp in cold jar can not adjust the distance outside 20 millimeters of the ultraviolet lamps.Be located at the preceding ultraviolet ray disinfector of flowing water Valve, can only the water of the sterilizer of flowing through be carried out disinfection, that is to say whenever the user fetches water, ultraviolet ray disinfector all must the energising operation.If ultraviolet lamp is arranged to time opening sterilization, because of the scope of sterilization little, so the reliability of sterilizing is not high.If ultraviolet lamp is arranged to altar lamp, though can improve the sterilizing reliability, cause the life-span of ultraviolet lamp short, energy consumption is big, and the ultraviolet lamp liberated heat can make water temperature rise, make deteriorating water quality, for example mouthfeel descends, and also has document announcement that nitrite concentration is risen.
The 4th class is an ozone disinfection, and for example the ozone that regularly ozone generator is produced leads in the water in the water dispenser bucket.Be no problem on this theoretical method, the ozone generator of a function admirable for example is set, an ozone mixing arrangement is set again, ozone is dissolved in the water, the part that will contact with ozone adopts the stainless steel material manufacturing of anti-ozone corrosion simultaneously.But such product is owing to system complex, and cost is too high, does not have the good market competitiveness.
