Detailed Description
In order that the above objects, features and advantages of the application will be readily understood, a more particular description of the application will be rendered by reference to the appended drawings. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present application. The present application may be embodied in many other forms than described herein and similarly modified by those skilled in the art without departing from the spirit of the application, whereby the application is not limited to the specific embodiments disclosed below.
As shown in fig. 1, in one embodiment, there is provided a control method of a dish washing apparatus 10, in particular, as shown in fig. 2 and 3, the dish washing apparatus 10 includes a washing chamber 11, a turbidity detecting member 12 is provided in the washing chamber 11, and the control method includes the steps of:
after the pre-washing stage is finished, standing for a first preset time period;
after waiting a first preset period of time, cleaning the surface residues of the turbidity detecting member 12;
after removing the residues on the surface of the turbidity detecting member 12, standing still for a second preset time period, and controlling the turbidity detecting member 12 to work to obtain a turbidity judgment value.
In the control method of the dish washing apparatus 10 provided in the above-mentioned aspect, first, after the pre-washing stage is finished, the dish washing apparatus stands still for a first preset period of time, so that the dirty water is in a substantially stationary state, and the accuracy of detection of the turbidity detecting member 12 is prevented from being affected by the vibration of the water wave. On the other hand, since the turbidity detecting member 12 performs the turbidity detection when the stained water is substantially at rest, there is a case where residues in the stained water float on the turbidity detecting member 12, thereby affecting the detection accuracy of the turbidity detecting member 12. Therefore, after the first preset time period is stopped, the turbidity detecting element 12 is not started immediately to perform turbidity detection, but the turbidity detecting element is firstly kept stand for a second preset time period after the residues on the surface of the turbidity detecting element 12 are removed, and then the turbidity detecting element 12 is controlled to work to perform turbidity detection to obtain a turbidity judgment value. Thereby improving the accuracy of turbidity detection and the washing effect.
Specifically, in one embodiment, as shown in fig. 2 and 3, the dish washing apparatus 10 further includes a sensing piece washing pump 13, wherein the sensing piece washing pump 13 is configured to spray water to the turbidity sensing piece 12. In other words, the detecting member cleaning pump 13 is started to spray water to wash the surface of the turbidity detecting member 12, thereby removing the residue floating on the surface of the turbidity detecting member 12.
On the basis of this dish washing apparatus 10, said removal of surface residues from said turbidity detecting member 12 comprises the steps of:
the test piece cleaning pump 13 is intermittently started.
The detecting piece cleaning pump 13 is intermittently started, and then water is intermittently sprayed to the turbidity detecting piece 12 to wash residues on the surface of the turbidity detecting piece 12.
Of course, in alternative embodiments, other means of cleaning the surface of the turbidity detection member 12 may be used. Such as by creating a large number of bubbles on the surface of the turbidity detecting member 12 so that when these bubbles burst, residues on the surface of the turbidity detecting member 12 can be removed.
Further, in one embodiment, the cleaning of the surface residue of the turbidity detecting member 12 comprises the steps of:
intermittently starting the detecting piece cleaning pump 13;
and said intermittently activating said test piece washing pump 13 includes the steps of:
interval 2s controls the test piece cleaning pump 13 to start once and thus cycle 5 times.
After standing for a first preset time period, spraying water to the turbidity detection member 12 by the detection member cleaning pump 13 every 2s, repeating for 5 times, stopping the detection member cleaning pump 13, and after standing for a second preset time period, detecting the turbidity detection member 12 to obtain a turbidity determination value.
Further specifically, in one embodiment, the first preset duration is 30s.
After the pre-wash phase is completed, the turbidity detection member 12 is cleaned of surface residues after waiting for 30 seconds.
Similarly, in some embodiments, the second preset duration is 10s.
After the residues on the surface of the turbidity detection member 12 are removed, waiting for 10 seconds, and then recovering the stain level to calm, controlling the turbidity detection member 12 to work, and detecting the turbidity determination value of the sewage at the moment.
Further specifically, in one embodiment, the pre-wash stage comprises the steps of:
s1, injecting cleaning water into the cleaning cavity 11;
s2, the cleaning water is pumped into the spray arm 15 by utilizing a cleaning pump, so that the cleaning water washes stains on the surface of the tableware, and the cleaning water becomes sewage.
After the pre-washing stage is finished, the greasy dirt and residues on the tableware are basically washed and mixed into the cleaning water, and the turbidity determination value of the sewage can reflect the real pollution degree of the tableware.
Further, in one embodiment, after the step S1 and before the step S2, the method further includes the steps of:
and after standing for a third preset time period, controlling the turbidity detection member 12 to work to obtain a turbidity calibration value.
In other words, after the washing water is injected, the washing water does not wash the dishes at this time. The turbidity calibration value obtained at this time can be understood as a reference value, and can be compared with the turbidity judgment value obtained later to obtain a more accurate turbidity value for judging the pollution degree of the tableware.
Specifically, the third preset duration may be 30s.
After the pre-washing stage is started, the resting is stopped for 30 seconds after the washing water is injected into the washing chamber 11. If the washing water is pumped into the washing chamber 11 by a driving means such as a water pump, the water pump should be stopped after the washing water is injected. If the wash water is introduced into the wash chamber 11 under pressure in the tap water pipe, the dish washing device 10 has a switching element for controlling the injection of the wash water, which is closed when the injection of the wash water is completed.
After the washing water is kept stand for 30 seconds, the turbidity detection member 12 starts to detect the data as a turbidity calibration value.
When the turbidity detecting member 12 detects the turbidity calibration value, the washing pump is started, and the spray arm 15 sprays water to wash tableware. After the pre-wash phase is completed, stains on the tableware are roughly washed and mixed in water to form sewage. After the pre-washing stage is finished, the mixture is kept still for 30 seconds. After this rest phase is completed, the test piece cleaning pump 13 is started. Specifically, the test piece cleaning pump 13 is started once every interval of 2s, and this is repeated 5 times. After repeating 5 times, the detecting member cleaning pump 13 stops operating, and then enters a stationary state. After 10 seconds of standing, the turbidity detecting member 12 starts the detected data as the turbidity determination value.
Still further, in an embodiment, the control method further comprises the steps of:
and determining a turbidity value according to the turbidity calibration value and the turbidity judgment value, and selecting a washing mode according to the turbidity value, wherein the higher the turbidity of the stain water displayed by the turbidity value is, the longer the subsequent washing time corresponding to the selected washing mode is.
The longer the turbidity of the stain water displayed by the turbidity value is, the longer the tableware is cleaned, and the washing mode is intelligently controlled according to the amount of the stains on the tableware.
Specifically, in some embodiments, the turbidity value = turbidity determination value/turbidity calibration value.
It is understood that the greater the difference between the turbidity determination value and the turbidity calibration value, the greater the water quality change before and after the surface pre-washing stage, thereby indicating that the more stains are on the tableware, and thus the longer the cleaning time is required.
Specifically, in one embodiment, the dish washing apparatus 10 has four wash modes, wash mode A1, wash mode A2, wash mode A3, and wash mode A4, respectively. Assuming that the main wash phase duration of the wash pattern A2 is a normal duration, the main wash phase duration of the wash pattern A1 is shorter than the main wash phase duration of the wash pattern A2, the main wash phase duration of the wash pattern A3 is prolonged with respect to the main wash phase duration of the wash pattern A2, and the main wash phase duration of the wash pattern A4 is identical to the main wash phase duration of the wash pattern A3, but the wash pattern A4 is increased by one rinse phase with respect to the wash pattern A3. In combination, the subsequent washing durations of the washing pattern A1, the washing pattern A2, the washing pattern A3, and the washing pattern A4 are sequentially increased.
The turbidity values are in different range values and different washing modes are correspondingly selected.
Further, the control method further includes the steps of:
the turbidity value is in S1-S2, and a washing mode A1 is selected;
the turbidity value is in S3-S4, and a washing mode A2 is selected;
the turbidity value is in S5-S6, and a washing mode A3 is selected;
and selecting a washing mode A4 when the turbidity value is between S7 and S8, wherein S1 is more than S2 and S3 is more than S4.
The values of the specific values S1, S2, S3 and S4 may be set according to the actual situation of the user, and are not specifically limited herein.
Further, in some embodiments, the pre-washing stage further comprises, after step S1, the step of activating a heating element to heat the water in the washing chamber 11.
