Description
Technical field
The present invention relates to the washing machine technical field, be specifically related to washing agent residue detection device and detection method thereof on a kind of washing machine cleaning clothes.
Background technology
To all adding suitable surfactant as washing agent, the dirt of clothing to be removed in the cleaning of clothing, clothing is the mechanism such as mutually to clash in current, laundry barrel and the mutual friction mutually between laundry the foul that is attached on clothing is broken away from.After dirt on clothing is removed, along with healthy, green life idea are rooted in the hearts of the people, the residue problem of washing agent residual on clothing is also received increasing concern.Because residual on clothing have a washing agent, not only injure dress material, more the skin of human body there is certain injury; Residual washing agent is considered to bring out human allergy's one of the main reasons at present.
Clothing in family all adopts washing machine to clean at present, washing machine according to the program of setting clean length by length, rinsing, dehydration, it can not identify what of amount of the washing agent that adds, and whether also residual on clothing after judgement that more can not be clear and definite or the rinsing of the information of detection have a washing agent.Judge washing machine cleans on clothing whether the residual of washing agent is arranged later, only in the airing process of clothing, it is simply judged at present, perhaps reexamines the remaining trace of washing agent on it after clothing dries.
At present people clean the injury of residual washing agent to clothing or human body on clothing later in order to reduce, and normally the rinsing number of times by increasing clothing or the use amount that reduces washing agent reach and reduce the residual of washing agent on clothing.But the rinsing number of times that increases clothing is inevitably waste water resource and electric energy, has increased use cost; And because the increase meeting of wash number has certain injury to clothing itself.If reduce the use amount of washing agent can affect the clean result of clothing, and causing clothes washing unholiness.
Summary of the invention
In order to solve above-mentioned deficiency, the invention provides a kind of residue detection device and detection method thereof of washing machine detergent.
A kind of residue detection device of washing machine detergent, comprise the sink of being located at the washing machine inner tub top, the washing machine inner tub delivery port is connected with the drainpipe with draining valve, described draining valve is electrically connected to the program controller of washing machine, the upper end of described drainpipe is provided with the water pipe that is communicated with it, and described water pipe is between washing machine inner tub delivery port and draining valve; Described water pipe inside is provided with the checkout gear for detection of its aqueous solution resistance, and the output of described checkout gear is electrically connected to described program controller; Described washing machine inner tub top is provided with the first water inlet pipe of the first water intaking valve and the second water inlet pipe with the second water intaking valve, and described the second water inlet pipe passes through sink; Described the first water intaking valve, the second water intaking valve are electrically connected to described program controller respectively.
Described checkout gear is the first test probe and the second test probe, and described the first test probe and the second test probe are located at respectively top and the middle part of water pipe inside.
Because the Main Ingredients and Appearance of washing agent comprises surfactant, auxiliary agent, filler, organized enzyme etc., generation current changes along with the variation of the electrolyte concentrations such as inorganic acid, alkali, salt or organic charged colloidal particle in solution due to electrolyte ionization being arranged in detergent solution.According to the electric resistance partial pressure principle, the unit resistance of solution is less shows that the electric conductivity of solution is stronger, so in washing machine sewer pipe, the concentration of washing agent is larger, its unit resistance is less, otherwise larger.The present invention according to water pipe that washing machine sewer pipe communicates in the resistance variations indirect detection of the aqueous solution go out the concentration of washing agent, then judge through washing machine to clean on clothing whether the residual of washing agent is arranged later.And then determine according to its resistance situation the number of times whether needs are set up rinsing, and reduce the residual injury to clothing, human body of washing agent thereby reach, make the more intelligent and hommization of washing machine.
A kind of residual method of above-mentioned washing machine detergent that detects comprises the following steps:
(1) open washing machine after, program controller is opened the first water intake valve after be full of water pipe, closes the first water intaking valve;
(2) the first test probe of water pipe inside and the second test probe are connected the resistance circuit that detects the aqueous solution, and program controller detects according to the resistance variations on testing circuit the AD value that in water pipe, the voltage of water when not adding washing agent is corresponding and is AD1, and storage;
(3) program controller is opened the second water intaking valve, the washing agent in sink is added in washing machine inner tub clothing is cleaned;
(4) carry out after last rinsing program finishes until washing machine, program controller is opened draining valve, and the water in washing machine inner tub is carried out draining when resetting water level, closes draining valve;
(5) open the laundry machine dehydration key, clothes dewatering to water pipe is closed after being full of water;
(6) the first test probe of water pipe inside and the second test probe are connected the resistance circuit that detects the aqueous solution, and program controller is AD2 according to AD value corresponding to voltage that the resistance variations on testing circuit detects in the rear water pipe of washing machine rinsing end, and storage;
(7) contrast AD1 and AD2, if AD1 and AD2 near the time, washing machine according to cleaning procedure operation dehydration after end; If AD2 is greater than AD1, program controller increases a rinse cycle after controlling laundry machine dehydration, until AD1 and AD2 relatively more approaching till.
In described step (1), the flooding time of the first water intaking valve is 5-10 second.
In described step (5), dewatering time is 4-6 second
So this checkout gear is simple in structure, cost is low; The precision of the result that detection method detects is high, signal stabilization; And in the drainpipe after finishing according to rinsing, the resistance of the aqueous solution of resistance when not adding washing agent of the aqueous solution compares, thereby reaches in the concentration that judges washing agent and clothing whether the residual of washing agent is arranged; And can increase the number of times of rinsing according to actual conditions, reach and reduce the residual injury to clothing, human body of washing agent, make the more intelligent and hommization of washing machine.
