Description
Technical field
The utility model relates to water dispenser pick-up unit field, particularly relates to a kind of water system leakage detection apparatus and leak hunting method thereof of water dispenser.
Background technology
The water system leakage problem of water dispenser is the problem that always perplexs a ubiquity of water dispenser manufacturing, also is that customer complaint is claimed damages one of maximum quality problems of dispute with causing at most.The water system leak hunting method of general water dispenser all is artificial water inspection method in the water dispenser industry at present, namely by manually the water system of water dispenser being filled with water, the manual observation by certain hour again is according to having or not dripping phenomenon to judge whether water system exists leakage problem.
The major defect of above-mentioned leak hunting method is as follows: the one, and manual observation occurs undetected because of the impact of sight line, light and observing time easily; The 2nd, can't in time find the very little infiltration phenomenon of leakage rate (unless have time enough to observe, but do like this leak detection speed too low, can't carry out aborning); The 3rd, after the water system of water dispenser adds water leak detection, even the water in the water system has been given out light fully, also can't remove remaining water in the hot cylinder of water system and the pipeline, the bacterium amount reproduction that this can cause in the water system of water dispenser directly affects user's health; The 4th, because of hygienic issues, the water that adds water dispenser can only bleed off as waste water after leak detection is finished, and can't reuse, and this has just caused a large amount of wastes of water resource; The 5th, in order to shorten the production cycle, artificial water inspection method can only be carried out synchronously with the functional test of drinking machine heating and refrigeration, needs to consume a large amount of electric energy.
Because the major defect that artificial water inspection method exists has enterprise to change water inspection method into pressure abroad and does the inspection method.The method of this leak detection is after water dispenser is finished assembling, pressed gas is enclosed in the water system of water dispenser, by observing in the certain hour, if the water system internal pressure is without obvious decline, namely be judged as water system and do not have leakage, such as pressure obvious decline is arranged, then be judged as water system and have leakage.
The advantage that above-mentioned pressure is done the inspection method is simple in structure, but because manometric display precision can't reach the requirement that shows that slight pressure descends, most cases still will rely on reviewer's experience to judge, so still there is the problem of erroneous judgement in this method, and also can't find at short notice the infiltration phenomenon that leakage rate is very little.
