By the above-mentioned means, flow sensor is made only to need to detect water inlet, so that it may realize to detergent injected volume Carry out the purpose of accurate quantification detection;Meanwhile it effectively preventing leading to flow sensing because detergent is different from water inlet water flow viscosity The generation for the problems such as device detection accuracy is insufficient.
In the present embodiment, suction runner, which replaces at interval of certain period of time with detergent storage chamber and inlet pipeline, to be connected It is logical, alternately to aspirate detergent and water inlet;Within the period that detergent storage chamber is connected with suction runner, outflow is taken out The inflow for inhaling runner is detected, and detected value is the detergent amount pumped corresponding to the secondary process.
In the present embodiment, interval time section need to be less than the time that detergent is all flowed into suction runner;Preferably, it aspirates The Lifetime of runner and detergent storage chamber and inlet pipeline is different value, and aspirates runner and detergent storage chamber Lifetime is less than the ratio of suction channel volume and detergent flow velocity.
In the present embodiment, the switching time node of reversal valve set by suction runner entrance is judged, can be to reach When set period of time t1, the detergent in runner will be aspirated by, which being determined as automatically, is all discharged, and is accordingly switched to and water inlet phase Connection;And when reaching set period of time t2, be judged to aspirating in runner automatically being all full of by water inlet, and be accordingly switched to Detergent is connected.
The medium in suction runner can also be determined automatically, and then determine switching time in the following way Point;Such as: during suction runner is connected with detergent storage chamber, if the detection accuracy of flow sensor changes When, it is judged to aspirating in runner washed agent and is stuffed entirely with, then is switched to and suction runner is connected with inlet pipeline, detergent Single injected volume be aspirate runner maximum volume.
Or quantitative manner is used, the medium in suction runner is determined, and then determine switching time node;Example Such as: when aspirating runner and switching to the timing node being connected with detergent storage chamber, the measured value of flow sensor into Row is accumulative, to obtain the water yield for flowing out suction runner, when the water yield of measurement reaches the single maximum injected volume of suction runner Afterwards, adjustable change valve enables suction runner be connected with inlet pipeline, and after flooding time reaches setting time T, will be in runner Detergent all rinse well after, then adjustable change valve enables suction runner be connected with detergent storage chamber, executes again Extract detergent program.
In the present embodiment, detailed process is as follows for above-mentioned automatic release device control method,
Step S1. automatic release device is started to work;
Step S2. suction runner is connected with inlet pipeline, until suction runner outflow water stream;
Step S3. suction runner is connected with detergent storage chamber, and detergent starts to be pumped into suction runner;
Step S4. detects the inflow of suction runner outflow, and judges whether detected value reaches setting injected volume; Step S6 is executed if reaching, if not up to executing step S5;
Step S5. judges to aspirate whether runner flows out detergent;If then stopping detecting, will test value and be included in accumulated value, And execute step S6;If otherwise continuing to pump detergent;
Step S6. suction runner is connected with inlet pipeline, until suction runner outflow water stream;
Step S7. judges whether accumulated value reaches setting injected volume;S8 is thened follow the steps if reaching, if not up to executing step Rapid S3;
Step S8. automatic release device stops working.
The above is only presently preferred embodiments of the present invention, is not intended to limit the present invention in any form, though So the present invention has been disclosed as a preferred embodiment, and however, it is not intended to limit the invention, any technology people for being familiar with this patent Member without departing from the scope of the present invention, when the technology contents using above-mentioned prompt make it is a little change or be modified to The equivalent embodiment of equivalent variations, but anything that does not depart from the technical scheme of the invention content, it is right according to the technical essence of the invention Any simple modification, equivalent change and modification made by above embodiments, in the range of still falling within the present invention program.
