Detailed Description
The following examples illustrate the invention, but the invention is not limited to these examples. Modifications and equivalents of some of the technical features of the specific embodiments of the present invention may be made without departing from the spirit of the present invention, and they are all included in the scope of the claimed invention.
Referring to fig. 1, there is shown a control method of a dish washer of the present invention, comprising the steps of:
step S1, detecting the oxygen concentration Q1 in a dish washer before the tableware is put into the dish washer;
s2, detecting the oxygen concentration Q2 in the dish washer after the tableware is placed in the dish washer;
step S3, obtaining a first oxygen concentration difference according to the oxygen concentration Q1 and the oxygen concentration Q2;
s4, the dish washer enters a cleaning program;
s5, detecting the oxygen concentration Q3 in the dish washer after the dish washer is cleaned;
step S6, obtaining a second oxygen concentration difference according to the oxygen concentration Q2 and the oxygen concentration Q3;
and S7, controlling the dish-washing machine to carry out washing or ending the washing program according to the relation between the first oxygen concentration difference and the second oxygen concentration difference.
Step S1, detecting the oxygen concentration Q1 in the dish washer before the dish washer is put into the dish washer, wherein the step specifically comprises the following steps:
step S101, detecting whether a door body of the dish washer is changed from a closed state to an open state;
if yes, the oxygen concentration Q1 in the dish washer; if not, the process returns to step S101.
In step S1, before the dishes are placed in the dishwasher, the oxygen concentration in the dishwasher is approximately equal to the oxygen concentration in the air, and the oxygen concentration in the dishwasher is Q1.
Step S2, detecting the oxygen concentration Q2 in the dish washer after the tableware is placed in the dish washer, wherein the step specifically comprises the following steps:
step S201, detecting whether the door body of the dish washer is changed from an open state to a closed state;
if yes, the oxygen concentration Q2 in the dish washer; if not, return to step S201.
In step S2, after the dishes are placed in the dishwasher, the oxygen concentration in the dishwasher is Q2 due to the bad smell of the residues in the dishes, which results in a decrease in the oxygen ratio, i.e., the oxygen concentration in the dishwasher.
Then, step S3 is performed to obtain a first oxygen concentration difference according to the oxygen concentration Q1 and the oxygen concentration Q2. Step S3, the method for obtaining the first oxygen concentration difference according to the oxygen concentration Q1 and the oxygen concentration Q2 comprises the following steps:
Δq1= |q1-q2|, wherein Δq1 is a first oxygen concentration difference, Q1 is an oxygen concentration in the dishwasher before the dishware is placed in the dishwasher, and Q2 is an oxygen concentration in the dishwasher after the dishware is placed in the dishwasher.
The dish washer enters a cleaning program, and the step S4 of the dish washer entering the cleaning program specifically comprises the following steps:
spraying and cleaning tableware in the dish washer;
crushing food residues;
slag discharging and flushing;
and drying the tableware in the dish-washing machine.
Step S5, after the cleaning in the dish washer is finished, the step of detecting the oxygen concentration Q3 in the dish washer is specifically as follows:
step S501, detecting whether a preset time is elapsed after the washing in the dish washer is finished;
if yes, detecting the oxygen concentration Q3 in the dish washer; if not, the process returns to step S501.
In step S501, the preset time is 2-5min.
Step S6, the method for obtaining the second oxygen concentration difference according to the oxygen concentration Q2 and the oxygen concentration Q3 comprises the following steps:
Δq2= |q3-q2|, wherein Δq2 is a second oxygen concentration difference, Q2 is the oxygen concentration in the dishwasher after the tableware is placed in the dishwasher, and Q3 is the oxygen concentration in the dishwasher after the washing in the dishwasher is completed.
When the dishwasher performs a washing procedure, residues in the tableware are reduced, the oxygen concentration in the dishwasher is increased, and the oxygen concentration in the dishwasher is Q3. Q3 is greater than Q2.
In the actual dish washer cleaning process, possibly because the cleaning effect is bad, the oxygen concentration in the dish washer is little different before the dish washer is cleaned and after the dish washer is cleaned, and the condition that Q3 is smaller than Q2 possibly appears at this time because the detection error exists in the detection device of the oxygen concentration. The absolute value of the Q3-Q2 result is taken by the delta Q2, so that the delta Q2 is ensured to be a positive number, and comparison is facilitated.
Step S7, controlling the dish-washing machine to wash or end the washing program according to the relation between the first oxygen concentration difference and the second oxygen concentration difference, wherein the step specifically comprises the following steps:
step S71, detecting whether the first oxygen concentration difference is larger than the second oxygen concentration difference;
if yes, go to step S72; if not, go to step S73;
step S72, controlling the dish washer to wash again;
step S73, the cleaning process is ended.
The first oxygen concentration difference Δq1 is the difference in oxygen concentration between before the dish is placed in the dishwasher and after the dish is placed in the dishwasher; the second oxygen concentration difference Δq2 is the difference in oxygen concentration in the dishwasher after and before dish washing.
Comparing the first oxygen concentration difference delta Q1 with the second oxygen concentration difference delta Q2, if the first oxygen concentration difference delta Q1 is larger than the second oxygen concentration difference delta Q2, the fact that residues still exist in the dish washer is indicated, residues on tableware are possibly not cleaned, residues or broken residues in the dish washer are possibly not discharged completely, so that the situation that the residues still exist in the dish washer and peculiar smell exists, the oxygen concentration ratio is low is avoided, and the dish washer is controlled to clean again.
If the first oxygen concentration difference delta Q1 is equal to the second oxygen concentration difference delta Q2, the ratio of the oxygen concentration in the dish-washing machine to the oxygen concentration in the air is approximate, the oxygen concentration is restored to the original ratio state, at the moment, the first oxygen concentration difference is equal to the second oxygen concentration difference, no residues or few residues exist in the dish-washing machine, and at the moment, the dish-washing machine is controlled to finish the washing procedure.
Preferably, after step S71, the following steps are further included between step S72:
step S74, detecting whether the difference between the first oxygen concentration difference and the second oxygen concentration difference is larger than a preset value;
if yes, go to step S72; if not, the process advances to step S73.
Comparing the first oxygen concentration difference delta Q1 with the second oxygen concentration difference delta Q2, and if the difference between the first oxygen concentration difference delta Q1 and the second oxygen concentration difference delta Q2 is larger than a preset value, indicating that residues in the dish washing machine are more, and controlling the dish washing machine to wash again; if the difference between the first oxygen concentration difference Δq1 and the second oxygen concentration difference Δq2 is smaller than the preset value, the residue in the dishwasher is still present, but the residue is less, and the dishwasher is controlled to end the washing process.
The invention provides a control method of a dish washer, which is used for effectively detecting the residual condition of residues before and after the dish washer is washed, ensuring the cleaning of the residues in the dish washer and avoiding the situation that the dish washer still has more residues or the crushed residues are not discharged after the dish washer finishes the washing procedure, so that the user experience is poor.
The above-mentioned preferred embodiments should be regarded as illustrative examples of embodiments of the present application, and all such technical deductions, substitutions, improvements and the like which are made on the basis of the embodiments of the present application, are considered to be within the scope of protection of the present patent.
