Before the product leaves factory, the different cleaning parameters of each cleaning process can be respectively adjusted and tested through experiments, and then the maximum threshold value X of the overflow parameter can be respectively obtained for different cleaning processesmaxAnd overflow parameter minimum threshold XminWherein X ismax＞XminIs greater than 0. Maximum overflow parameter threshold XmaxAnd overflow parameter minimum threshold XminThe acquisition principle is that when the X calculated according to the real-time water inflow and the rotating speed of the spraying motor 7 is larger than the maximum threshold value X of the overflow parametermaxWhen the door body is opened, the water flow overflows. When X calculated according to the real-time water inflow and the rotating speed of the spraying motor 7 is smaller than the minimum threshold value X of the overflow parameterminWhen the door body is opened, the condition of water flow overflow can not occur. Thus, whether flooding occurs or not can be determined by the following contents.
If the current cleaning machine is in a door closing state: respectively reacting X with Xmax、XminComparing; if X > XmaxJudging that overflow occurs; if X ismin≤X≤XmaxJudging whether the spraying pressure value on the door plate of the cleaning machine can be detected or not, if so, judging that overflow can occur, and if not, judging that the overflow can not occurJudging that no overflow occurs; if X < XminJudging whether the spraying pressure value on the door panel of the cleaning machine can be detected or not, if so, indicating that the water flow is X < XminThe door panel is opened, which may be caused by other factors such as irregular tableware placement, but in order to avoid water jet during door opening, water overflow occurs in the judgment, and X is setminX, so can be based on X and XminThe overflow condition of the water flow can be judged more accurately; if not, it is determined that no flooding has occurred.
If the present cleaning machine is in when opening the door state, the door body of cleaning machine is in open state, usually rivers can't reach on the pressure sensor 21 of the door body, unable rethread pressure data helps judging the condition that rivers are excessive this moment, under the condition of opening of the door body, if can also satisfy the condition that the door body was opened at normal washing parameter, the cleaning machine then still is in normal condition, if the condition that the washing flow switches over and leads to the washing parameter to change this moment, whether can also satisfy the condition of opening the door after needing to estimate the washing parameter to change, also need carry out the calculation of the excessive parameter value X that new washing parameter corresponds and judge whether can take place the overflow this moment, this new excessive parameter value X is following X1 in the step after opening the door body. In order to avoid overflow as much as possible, only X and X are usedminComparing; if X > XminJudging that overflow occurs; if X is less than or equal to XminAnd judging that no overflow occurs.
