Abstract
The invention discloses a water dispenser used water system leak detection device and method, which mainly adopt the flow interference detection method and a low-cost gas flow detection device consisting of a high-sensitivity gas flow detection pipe and a high-sensitivity induction detector, rather than a high-price precision flowmeter. When the fact that pressure gas for detecting a water system of the water dispenser enters the water system of the water dispenser and is balanced is detected, an air floater inside the gas flow detection pipe can drift as long as leakage exists in the water system of the water dispenser, the displacement of the floater can be detected by the induction detector immediately, and the detecting system locks a signal and alarms immediately.
Description
Technical field
The present invention relates to water dispenser pick-up unit field, particularly relate 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; Promptly by the water system fills with water of manual work with water dispenser; Manual observation through 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 following: the one, and omission takes place because of the influence of sight line, light and observing time in manual observation easily; The 2nd, can't in time find the very little infiltration phenomenon of leakage rate (only if there is time enough to observe, but it is too low to do leak detection speed like this, can't carry out aborning); The 3rd, the water system of water dispenser even the water in the water system has been given out light fully, also can't be removed remaining water in hot cylinder of water system and the pipeline after adding the water leak detection, and this can cause the interior bacterium of water system of water dispenser to breed in a large number, directly influences 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 accomplished, 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 with the functional test of water dispenser heating and refrigeration synchronously, 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 accomplished assembling, pressed gas is enclosed in the water system of water dispenser, through observing in the certain hour; If the water system internal pressure does not have obvious decline; Promptly be judged as water system and do not have leakage, obvious decline is arranged, then be judged as water system and have leakage like pressure.
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 make judgement; So still there is the problem of erroneous judgement in this method, and also can't find the infiltration phenomenon that leakage rate is very little at short notice.
