In addition, as described in the previous embodiment, aforesaid pause step (S200) is only carried out once, still, also can carry out more than at least twice as required.
Below, will the final feedwater step (S300) in the water supply control method of the present invention be described in detail.
Above-mentioned final feedwater step (S300) is after above-mentioned pause step (S200) finishes, control feed-water valve 110, make washings supply to setpoint frequency (promptly, final water level) (F1), thus remove a series of processes of washing agent residual in the position that the effuser 124 of distributor body 122 forms fully.
Promptly, in feedwater step (S100), fail in time the washing agent that effuser 124 by distributor body 122 flows out, near position with the above-mentioned effuser 124 in the bottom surface that remains in the above-mentioned distributor body 122, but, before above-mentioned residual washing agent adheres to, to supply with washings once more by above-mentioned final feedwater step (S300), thereby make above-mentioned washing agent obtain fully discharging by above-mentioned effuser.
Wherein, in above-mentioned feedwater step (S100), the reason that above-mentioned washing agent fails to flow out fully is, in the process that above-mentioned washing agent and washings flow out by above-mentioned effuser 124, owing to causing a part of washings, the outflow of too much washings forms eddy current, and around the arrival end of above-mentioned effuser 124, carry out eddy flow, promptly, under the effect of the eddy current of above-mentioned generation, carry out in the process of pause step after the feedwater step finishes, the part of the washing agent that contains in washings and the above-mentioned washings will remain near the position of above-mentioned effuser 124.
Consequently, by carrying out aforesaid feedwater step (S100), pause step (S200) and the step (S300) that finally feeds water successively, can prevent the residual washing agent in inside of distributor body 122.
In addition, the water supply control method of the car washing installation in the embodiment of the invention is not only to carry out with the process of previous embodiment.
For example, together supply with time of washings, preparation wash time and main wash time are arranged usually with washing agent.
Thus, when the preparation wash time, can prevent the phenomenon that washing agent is residual fully by a series of processes in the embodiment of the invention.But, under situation as long-time supply washings such as main wash times, because the eddy current that produces on the position that the effuser 124 of distributor body 122 forms, washing agent will flow to the front side in the above-mentioned distributor body 122, and may be attached on the corresponding site.
Therefore, as the long-time stroke of supplying with washings such as main wash time in, be preferably in the process of carrying out above-mentioned feedwater operation, carry out the ON/OFF control of feed-water valve 110 more than at least once repeatedly.
And the control of the ON/OFF of above-mentioned feed-water valve 110 is preferably in the feedwater initial stage to be carried out, and this is because at the feedwater initial stage, most of washing agent is mixed in washings, and flow to above-mentioned distributor body 122.
Wherein, the ON/OFF of above-mentioned feed-water valve 110 control can be according to feedwater time of integral body and difference, but preferably carry out the roughly number of times below 10 times more than at least 3 times.
This is because under the situation of the ON/OFF control of carrying out too frequent feed-water valve 110, owing to the increase of whole feedwater time, will cause user's being discontented with product; If under the situation of crossing the ON/OFF control of not carrying out feed-water valve 110 in long-time, the washing agent front side to distributor body 122 in as previously mentioned is mobile.
As mentioned above, the water supply control method of the car washing installation among the present invention can change to the method for various embodiments as required.
