Description

TECHNICAL FIELD

[0001] The present application relates to the field of detecting the rinsing degree of a cleaning mechanism, and in particular to a rinsing detection method for a cleaning mechanism and application. BACKGROUND

[0002] After completing the washing of washing objects, the cleaning mechanism such as a dishwasher, a washing machine, and a shoe washing machine needs to be rinsed to avoid the detergent remaining on the washing objects and affecting the use of the washing objects.

[0003] The existing method for detecting whether the washing objects are rinsed clean usually detects the light transmittance of sewage after washing to determine the rinsing degree. Specifically, the method includes a detection pipeline and a light transmittance tester. The sewage flows through the transparent detection pipeline, and the tester determines the light transmittance of the sewage by detecting the light transmittance of the pipeline. When the washing objects are not rinsed clean, a large amount of foam is contained in the sewage, the light transmittance of the detection pipeline is low, and the preset value cannot be reached. When the washing objects are rinsed clean, there is no foam in the washing water, the light transmittance of the detection pipeline is high, and the preset value is reached, indicating that the washing objects are rinsed clean. The method needs to make the sewage flow through the transparent pipeline, and determine the light transmittance of the sewage by detecting the light transmittance of the pipeline. If the pipeline is contaminated, the dirt on the inner wall or outer wall of the pipeline will affect the collection of the light transmittance, and further affect the determination of the rinsing degree, resulting in misjudgment.

[0004] Therefore, how to accurately determine whether the washing objects are rinsed clean is a technical problem to be solved. SUMMARY

[0005] The present application aims at the above-mentioned problems, and provides a rinsing detection method for a cleaning mechanism and application, which can effectively determine whether the washing objects are rinsed clean and avoid the excessive foam causing the detergent to remain on the washing objects.

[0006] The technical solution adopted by the present application is as follows: a rinsing detection method for a cleaning mechanism, the cleaning mechanism including a washing bin, a sewage tank connected to the water outlet of the washing bin, and liquid (including clean water, washing water, and rinsing water) in the washing bin being capable of entering the sewage tank from the water outlet; the method including the following steps: after at least one rinsing, the mth (m>1) rinsing,

[0007] S1: injecting clean water with a volume of C1 into the washing bin, the volume C1 being n times the volume C2 of the sewage tank; and rinsing the washing objects in the washing bin;

[0008] S2: after the rinsing is completed, conveying the rinsing water in the washing bin to the sewage tank, and discharging the rinsing water in the washing bin through multiple times of drainage of the sewage tank;

[0009] S3: set the number of times the sewage tank is filled as Y=Ceiling(n)+1, Ceiling(n) represents rounding up, such as Ceiling(1.9)=2; Ceiling(2)=2; Ceiling(2.1)=3; Y represents the number of times the sewage tank is set to be filled, even if the sewage tank cannot be completely filled with the volume C2 when it is filled for the Ceiling(n)+1th time, it is also determined that the sewage tank is filled, that is, the sewage tank is determined to be filled.

[0010] Specifically, after the liquid enters the sewage tank, due to the presence of detergent in the liquid, foam will accumulate on the surface of the liquid in the sewage tank, and the space occupied by the foam is C21, and the space occupied by the liquid in the sewage tank is C22, that is, in the sewage tank, C2=C21+C22.

[0011] If the detergent in the rinse water is completely diluted, that is, there is no foam on the surface of the rinse water, the rinse water is equivalent to water, and the space occupied by the foam C21=0, then the number of times the sewage tank is filled is Ceiling(n).

[0012] If the rinse water contains a small amount of detergent, that is, there is only a small amount of foam on the surface of the rinse water, then the number of times the sewage tank is filled is Ceiling(n) or Ceiling(n)+1, and in order to ensure that the rinse water in the washing bin is completely emptied, an additional air pumping and draining is added to verify whether the rinse water in the washing bin is completely emptied, therefore, it is preferred that the number of times the sewage tank is filled is set as Y=Ceiling(n)+1.

[0013] S4: determine and obtain the actual number of times y that the sewage tank is filled;

[0014] S5: compare the actual number y with the set number Y to determine whether the washing is clean;

[0015] S51: if y≤Y, it means that the detergent in the rinse water after this washing is completely diluted or only a small amount of detergent remains, there is no or only a small amount of foam on the rinse water, the space occupied by the foam is small, so that the actual number of times y that the sewage tank is filled is ≤ the number of times Y that the sewage tank is set to be filled, then the washing is clean;

[0016] S52: if y>Y, it means that there is a large amount of detergent in the rinse water after this washing, there is a large amount of foam on the rinse water, the space occupied by the foam is large, and the actual amount of rinse water discharged each time the sewage tank is filled is small, so that the actual number of times y that the sewage tank is filled is > the number of times Y that the sewage tank is set to be filled, then the washing is not clean.

[0017] Further, in step S52, if it is determined that the washing is not clean, the rinse water produced in this washing is completely discharged, and the next washing is performed, that is, steps S1-S5 are repeated until y≤Y.

[0018] It should be noted that when the m+1th rinsing is performed, the amount of clean water added to the washing bin can be different from the amount of clean water added during the mth rinsing, or can be the same; that is, the value of n is not a fixed value. For example, for a semi-automatic cleaning device, the addition of clean water requires manual operation, and manual addition is difficult to ensure that the amount of clean water is C1 each time the rinsing is performed. For another example, the amount of clean water added during the mth rinsing is n=1.9, and the final detection shows that the washing object is not rinsed clean. The m+1th rinsing is performed, and the m+1th rinsing can add n=3.6 of the amount of clean water to ensure that the clean water is sufficient, thereby improving the dilution effect of the dilution of the detergent during rinsing. For another example, the amount of clean water added during the mth rinsing is n=2.6, and the final detection shows that the washing object is close to being rinsed clean, but the washing object is still in a state of not being rinsed clean. The m+1th rinsing is performed, and the m+1th rinsing can add n=1.6 of the amount of clean water to save water resources.

[0019] Further, when each sewage tank is determined to be full, step S21 is performed;

[0020] S21: draining process; when it is determined that the sewage tank is actually full or the sewage tank is determined to be full, the sewage tank is completely emptied through the drain provided on the sewage tank, to provide preparation for the next time the sewage tank is filled with water.

[0021] Further, how to determine that the sewage tank is full;

[0022] The sewage tank is provided with a detection assembly for detecting whether the sewage tank is actually full;

[0023] The first mode: the sewage tank is actually full; if the detection assembly has a detection signal, the sewage tank is actually full; if the detection assembly does not have a detection signal, the sewage tank is not actually full.

[0024] Specifically, the detection assembly is at least one probe provided at the top of the sewage tank. The probe generates a detection signal when it contacts the liquid. When all the probes simultaneously detect the liquid, it indicates that the sewage tank is actually full.

[0025] It should be noted that first, the foam contains liquid, that is, the probe will also generate a detection signal when it contacts the foam; second, the number of probes should be as large as possible to ensure the accuracy of detecting that the sewage tank is full, and to avoid the splashes of water on the probe at the bottom of the sewage tank affecting the judgment of the probe.

[0026] The second way: the sewage tank is identified to be full; according to the flow of the washing tank into the sewage tank, the time required for the sewage tank to be full is set as T, that is, T represents the time required for the sewage tank to be full of only water when there is no foam in the sewage tank (that is, when C21=0); it should be noted that, considering that part of the water will be absorbed by the washing object, the length of time T should be longer than the length of time required for the sewage tank to be full of clean water directly flowing into the sewage tank, so as to squeeze out as much water on the washing object as possible and into the sewage tank; if the detection component still does not have a detection signal after the time T, the sewage tank is identified to be full.

[0027] Specifically, when the remaining washing water or rinsing water in the washing tank is insufficient to fill the sewage tank in volume plus the volume of the foam, that is, C21+C22

[0028] The actual number of times that the sewage tank is full is the sum of the above two ways.

[0029] Further, if the detection component has a detection signal at t0≤T time, there is still a large amount of liquid in the washing tank;

[0030] If the detection component has no detection signal at t0>T time, the liquid in the washing tank is completely drained.

[0031] Further, before step S1, there is also step S01 washing; specifically,

[0032] S011: washing; injecting clean water with a volume of C1 into the washing tank and adding a detergent, and the washing tank washing the washing object in the washing tank;

[0033] S012: completely draining the washing water after washing by x times step S21; after x times of the drainage process as described in step S21, the washing water containing the detergent is drained, so the surface of the washing water must have foam, that is, x≥Ceiling(n); thereby completing the washing process.

[0034] Further, when washing and first rinsing, the time for the sewage tank to be full each time is set as T1; after the first rinsing is completed, the time for the sewage tank to be full each time is set as T2; T1≤T2, that is, on the one hand, under the condition of completely draining the washing water, the washing time is reduced as much as possible; on the other hand, the draining time of the rinsing water is prolonged, which can squeeze out as much water and foam in the washing object as possible.

[0035] Further, the preset number of rinsing is m, m>2, so as to ensure that the washing objects are cleaned; of course, m=1 can also be selected according to the type of the washing objects, the material and the amount of the detergent.

[0036] Further, after the first rinsing, when the washing bin fills the sewage tank, only the time T is considered, that is, whether all the probes simultaneously detect that the sewage tank is filled with liquid within the time T, the sewage tank is emptied and the next air pumping operation is continued; this step is to dilute the foam as much as possible and discharge it with the washing water, reduce the subsequent detection times, and increase the amount of rinsing water filled in the sewage tank at a time, reduce the number of sewage tank filling and draining, and improve the washing efficiency.

[0037] Further, if x=Ceiling(n), it means that after washing, Ceiling(n) drainage processes are needed to completely discharge the washing water containing foam, that is, the amount of foam is small, the amount of washing water added is small, and the number of rinsing can be reduced, that is, the preset number of rinsing is modified to m-1 times.

[0038] Further, if n>1, the sewage tank will be actually filled at least once after washing or rinsing, and after washing or each rinsing, the time t0 at which the sewage tank is filled for the first time is greater than T, the liquid is stopped from entering the sewage tank and the sewage tank is emptied, and a fault alarm is performed; that is, because the volume C1 of the added water is greater than the volume C2 of the sewage tank, the sewage tank can be actually filled during the first drainage process, that is, all the probes can simultaneously detect the liquid within the time T; if the above situation occurs, a fault occurs, and a fault alarm is performed.

[0039] Further, the maximum number of rinsing is set to M times, and if the actual number of rinsing m>M>2, a fault alarm is performed; the endless rinsing is avoided, and the cleaning time is ensured.

[0040] The application of the rinsing detection method is applied to the rinsing system of the washing machine, which can determine whether the washing objects in the washing machine are rinsed clean, and avoid that the excessive foam causes the detergent to remain on the washing objects.

[0041] In summary, due to the adoption of the above technical solutions, the beneficial effects of the present application are:

[0042] 1、The present application sets the number of times the sewage tank needs to be filled to completely discharge clean water according to the relationship between the volume of clean water added to the washing bin and the volume of the sewage tank, and uses the fact that foam occupies space in the sewage tank. The number of times the sewage tank needs to be filled to completely discharge sewage with foam is higher than the number of times the sewage tank needs to be filled to completely discharge clean water. By comparing the actual number of times the sewage tank is filled with the set number of times the sewage tank is filled, it can be determined whether the rinsing water after rinsing contains foam, and further determine whether the washing is clean, avoiding excessive foam causing detergent to remain on the washing.

[0043] 2、The present application is applied to the rinsing system of a washing machine, which can determine whether the washing in the washing machine is clean, avoiding excessive foam causing detergent to remain on the washing. BRIEF DESCRIPTION OF DRAWINGS

[0052] All features disclosed in this specification, or all steps of any methods or processes disclosed, may be combined in any combination, except where such combinations are mutually exclusive.

[0053] Any feature disclosed in this specification, unless stated otherwise, can be replaced by any other equivalent or similar feature. That is, unless stated otherwise, each feature is one example only of a number of equivalent or similar features.

[0054] Example 1

[0055] As shown in Figure 1 A rinsing detection method of a cleaning mechanism is applied to a rinsing system of a washing machine, the rinsing system comprising a cleaning mechanism, the cleaning mechanism comprising a washing bin 1, the washing bin 1 being connected with a clean water tank 5, the clean water tank 5 being capable of supplying clean water participating in the cleaning process for the washing bin 1, a water outlet of the washing bin 1 being connected with a sewage tank 2, a volume C1 of the clean water tank 5 being 1.9 times of a volume C2 of the sewage tank 2, Ceiling(1.9)=2; of course, n=0.6; n=1.3; n=2.4; or n is other values, but in this embodiment, n=1.9 is taken as an example; three probes 3 are arranged at the top of the sewage tank 2 (of course, the more the probes 3, the higher the measurement accuracy; specifically, the purpose of arranging multiple probes 3 is to avoid the splashing of the water at the bottom of the sewage tank 2 on the probes 3 affecting the judgment of the probes 3); a time required for the sewage tank 2 being filled is set as T, that is, the time for the probes 3 being capable of simultaneously detecting the clean water in the sewage tank 2 is set as T; an actual time for the sewage tank 2 being filled is t0, that is, an actual time for the probes 3 being capable of simultaneously detecting the liquid in the sewage tank 2 is t0; the cleaning mechanism further comprises a gas suction and injection device, the gas suction and injection device sucking the gas in the sewage tank 2 to form a negative pressure in the sewage tank 2, and then making the washing bin 1 in communication with the sewage tank 2 contract to drain the washing water or the rinsing water in the washing bin 1 into the sewage tank 2; preferably, the gas suction and injection device is a gas pump 4; the washing bin 1 is a flexible washing bag.

[0056] It should be noted that, in order to save space, the following steps include step S21: as shown in Figure 3 the drainage process; specifically, the drainage process is as follows: the gas pump 4 sucks the gas in the sewage tank 2 to form a negative pressure in the sewage tank 2, the washing bin 1 being a flexible washing bag contracts under the action of the atmospheric pressure to squeeze the liquid (including the washing water or the rinsing water) in the washing bin 1 out of the washing bin 1, so that the liquid in the washing bin 1 and the liquid in the washing material enter the sewage tank 2; after a time T (the time of each drainage process in the washing and the first rinsing is T=T1=90s; the time of each drainage process in the remaining rinsing is T=T2=120s), or all the probes 3 can simultaneously detect the liquid in the sewage tank 2, it is considered that the sewage tank 2 has been filled with the liquid; the liquid in the sewage tank 2 is completely drained.

[0057] It should be noted that, in order to completely drain the liquid in the sewage tank 2, in addition to setting the drainage time to achieve it, a detection assembly such as a probe can also be arranged at the bottom of the sewage tank 2, when the detection assembly cannot detect the signal, it is determined that the liquid in the sewage tank 2 has been drained, avoiding the wire scraps blocking the drainage hole of the sewage tank 2, and the liquid in the sewage tank 2 not being completely drained to affect the next rinsing, affecting the rinsing detection result.

[0058] AsFigures 2-6 The washing process and all the rinsing processes are shown.

[0059] The washing process is step S01, which includes steps S011-S0123 in detail.

[0060] As shown in the figure, S01: washing; Figure 4

[0061] S011: inject all the clean water in the clean water tank 5 into the washing bin 1, and add detergent to the washing bin 1 to wash the washing materials in the washing bin 1.

[0062] S012: completely drain the washing water after washing through x = Ceiling(1.9) + 1 = 3 times of the draining process as described in step S21. For details, see steps S0121-S0123.

[0063] S0121: the first time the sewage tank 2 is filled with water and drained after washing, i.e., the first x = 1 time of step S21 to drain the washing water. If the sewage tank 2 is not actually filled with water within the set time T1 = 90s, i.e., after T1 = 90s (i.e., t0 > T), all probes 3 do not simultaneously detect the fullness of the sewage tank 2, it is possible that the machine has failed, and the water in the sewage tank 2 is drained and a fault alarm is given. If all probes 3 simultaneously detect the fullness of the sewage tank 2 within T1 = 90s, the water in the sewage tank 2 is drained and step S0122 is performed.

[0064] S0122: the second time the sewage tank 2 is filled with water and drained after washing, i.e., the second x = Ceiling(1.9) = 2 time of step S21 to drain the washing water. If the washing water has been completely drained this time, the number of rinsing times is correspondingly reduced by one. Specifically, after T1 = 90s (i.e., t0 > T), the sewage tank 2 is not actually filled with liquid (all probes 3 do not simultaneously detect the fullness of the sewage tank 2), it is considered that the amount of detergent added this time is less, and the number of rinsing times is correspondingly reduced by one, i.e., the first time of step S02 to rinse and drain is not performed, and the water in the sewage tank 2 is drained, and step S0123 is not continued, but step S03 to rinse and drain the second time is directly performed. If the sewage tank 2 is actually filled with liquid within T1 = 90s (all probes 3 simultaneously detect the fullness of the sewage tank 2), the water in the sewage tank 2 is drained and step S0123 to fill the sewage tank 2 with water and drain the third time after washing is performed.

[0065] ​S0123: The third time of the water filling and draining process of the sewage tank 2 after washing, i.e., the x = Ceiling (1.9) + 1 = 3 times of step S21, when the sewage tank 2 is not actually filled with water (all probes 3 do not have simultaneous detection data of the sewage tank 2 being full of water) after T1 = 90s (i.e., t0 > T), it is considered that the washing water has been completely drained from the washing bin 1, and the water in the sewage tank 2 is drained to perform the first rinsing step S02; if the sewage tank 2 is actually filled with liquid (all probes 3 simultaneously detect that the sewage tank 2 is full of water) within the set time T1 = 90s (i.e., t0 ≤ T), it is considered that the washing water added in this washing is too much; then increase the second rinsing step S03, and drain the water in the sewage tank 2 to perform the first rinsing step S02; or repeat step S0123, and again perform the draining of the washing water through step S21 until the sewage tank 2 is not actually filled after T1 = 90s (i.e., t0 > T).

[0066] It should be noted that in actual use, the concentration of washing water containing detergent is the highest among the rinsing water in the rinsing process, so during the washing step S01, the washing water in the washing bin 1 should be completely drained as much as possible to reduce the pressure of diluting the detergent in the subsequent rinsing; therefore, the washing water can be completely drained by x times of water filling and draining of the sewage tank 2, where x > Ceiling (n) + 1.

[0067] By comparing the time t0 when the sewage tank 2 is actually filled with water with the time T when the sewage tank 2 is set to be filled with water, and whether the probes 3 can have simultaneous detection data, the amount of detergent added is determined, and the number of rinsing is increased or decreased accordingly.

[0068] The above process is the entire washing process, and the entire rinsing process is described below, as shown in Figure 2 、 Figure 5 、 Figure 6 The rinsing process is after the washing process; in this embodiment, there are three rinsing processes, which specifically include steps; and in detail, steps S02-S04.

[0069] S02: first rinsing; all the clean water in the clean water tank 5 is added to the washing bin 1 to rinse the washing objects; the rinsing water in the washing bin 1 is transported to the sewage tank 2 through multiple drainage processes as described in step S21 to drain the rinsing water in the washing bin 1 through the sewage tank 2; specifically, after rinsing, y = Ceiling (1.9) + 1 = 3 times of the drainage process as described in step S21 is performed; every time the sewage tank 2 is filled with water from the washing bin 1, whether all the probes 3 simultaneously detect the data of the full water in the sewage tank 2 within T1 = 90s or not, the sewage tank 2 is emptied and the next air pumping drainage work is continued until y = Ceiling (1.9) + 1 = 3 times of the drainage process is completed; this step is to dilute and drain as much foam as possible with the washing water to reduce the subsequent detection times, therefore, the data recorded by the probes 3 is not analyzed and judged in the first rinsing of step S02.

[0070] S03: second rinsing; the clean water tank 5 is filled with clean water, and the clean water in the clean water tank 5 is added to the washing bin 1 to rinse the washing objects again; the rinsing water in the washing bin 1 is transported to the sewage tank 2 through multiple drainage processes as described in step S21 to drain the rinsing water in the washing bin 1 through the sewage tank 2; specifically, after rinsing, y = Ceiling (1.9) + 2 = 4 times of the drainage process is performed; the specific steps are the same as those of the first rinsing of step S02, except that the time is set to T = T2 = 120s and one more drainage process is added.

[0071] It should be noted that in the second rinsing step S03, the number of drainage processes is increased, on the one hand, to increase the number of times the flexible washing bin 1 is squeezed and deformed, and to increase the number of times the washing bin 1 squeezes the washing objects, so as to squeeze out as much moisture and foam as possible from the washing objects; on the other hand, in the first rinsing step S02, although 3 times of the drainage process is performed, the washing bin 1 may still not be completely drained (e.g., the amount of added washing water is excessive), and one more drainage process is added in the second rinsing drainage step S03 to ensure that the washing water in the washing bin 1 is drained; the set time in the second rinsing process S03 is extended to T2 = 120s, which aims to increase the single squeezing time and squeeze out as much moisture and foam as possible from the washing objects.

[0072] Of course, without considering the cleaning time, in the first rinsing step S02, the number of drainage processes y > Ceiling (n) + 1 = Ceiling (1.9) + 1 = 3, such as 4 times, as in the second rinsing step S03, and the time T1 can also be selected as T2 = 120s to increase the time and number of times of draining the liquid in the washing bin 1 at a time to squeeze out as much moisture and foam as possible from the washing objects.

[0073] It should be noted that, in the first draining process in the first rinsing step S02, the first draining process in the second rinsing step S03, if the sewage tank 22 is not filled with water within the set time T1 = 90s or T2 = 120s, i.e. after T1 = 90s or T2 = 120s, all probes 3 do not simultaneously detect that the sewage tank 2 is full of water, it is possible that the machine malfunctions, the sewage tank 2 is emptied and a fault alarm is given.

[0074] As shown in Figure 2 , Figure 6 the third rinsing S04, which is the mth rinsing in this embodiment, and the rinsing detection is performed in this rinsing, including steps S1, S2, S3, S4 and S5; in other embodiments, if m > 3, i.e. after multiple second rinsing steps S03, the step S04 is performed until the mth rinsing. The set time of each draining process in the third rinsing step S04 is T2 = 120s, which is longer than T1 = 90s, and the time is also extended to T2 = 120s, which is also to increase the length of single extrusion, and to extrude as much water and foam as possible from the washing materials.

[0075] S1: inject all the clean water in the clean water tank 5 into the washing chamber 1, i.e. inject clean water with a volume of C1 into the washing chamber 1, and the volume C1 of the clean water tank 5 is 1.9 times the volume C2 of the sewage tank 2; and rinse the washing materials in the washing chamber 1;

[0076] S2: deliver the rinsing water in the washing chamber 1 to the sewage tank 2, and discharge the rinsing water in the washing chamber 1 through multiple draining processes of the sewage tank 2; the rinsing water in the washing chamber 1 is discharged through the draining process S21 described above, and each draining process is that the rinsing water in the washing chamber 1 enters the sewage tank 2, and after a time T = T1 = 90s or T = T2 = 120s, or all probes 3 simultaneously detect the liquid in the sewage tank 2, the rinsing water in the sewage tank 2 is discharged; and the rinsing water in the washing chamber 1 is completely discharged through multiple draining processes.

[0077] S3: set the number of times that the sewage tank 2 is filled to Y = Ceiling(1.9) + 1 = 3, i.e. set that the clean water added can be completely discharged through three draining processes S21 of the sewage tank 2; specifically, when the Y = 1th draining process S21 is performed, the sewage tank 2 should be in an actually full state; when the Y = 2th draining process S21 is performed, the sewage tank 2 should be in an actually full state or a recognized full state; and when the Y = 3th draining process S21 is performed, the sewage tank 2 should be in a recognized full state.

[0078] S4: determine and obtain the actual number of times y that the sewage tank 2 is filled.

[0079] In step S4, the specific process of obtaining and determining the actual number of times y that the sewage tank 2 is filled is as follows.

[0080] S41: Obtain the number of times y that the sewage tank 2 is filled = 1; the y = 1 drainage process in the rinsing detection step, if the sewage tank 2 is not filled with water within the set time T2 = 120 s, i.e., after T2 = 120 s, all probes 3 do not simultaneously detect that the sewage tank 2 is full of water, the machine may be malfunctioning, empty the water in the sewage tank 2 and perform a fault alarm; if all probes 3 simultaneously detect that the sewage tank 2 is full of water within T1 = 120 s, empty the water in the sewage tank 2 and perform the second drainage process in the third rinsing drainage of step S042.

[0081] S42: Obtain the number of times y that the sewage tank 2 is filled = Ceiling(n); the y = Ceiling(1.9) = 2 drainage process in the rinsing detection step; it is necessary to analyze whether all probes 3 simultaneously detect liquid and the time at which the liquid is detected. Details are shown in steps S421 and S422.

[0082] S421: If in the y = Ceiling(1.9) = 2 drainage process, the probes 3 cannot simultaneously detect the liquid in the sewage tank 2 after T time, it is indicated that the y = Ceiling(1.9) = 2 drainage has completely drained the rinsing water in the washing bin 1, further indicating that there is no foam or a small amount of foam in the rinsing water drained this time, C21 (space occupied by foam) + C22 (space occupied by liquid) < C2 (space of the sewage tank 2), and the y = Ceiling(1.9) = 2 obtained this time is recorded.

[0083] S422: If in the y = Ceiling(1.9) = 2 drainage process, t0 ≤ T, i.e., the probes 3 can simultaneously detect the liquid in the sewage tank 22 within T time, it is indicated that there is a large amount of liquid or foam in the washing bin 1, and step S43 needs to be performed.

[0084] S43: Obtain the number of times y that the sewage tank 2 is filled = Ceiling(n) + 1; the y = Ceiling(1.9) + 1 = 3 drainage process in the rinsing detection step; it is necessary to analyze whether all probes 3 simultaneously detect liquid and the time at which the liquid is detected. Details are shown in steps S431 and S432.

[0085] S431: If the probe 3 cannot simultaneously detect the liquid in the sewage tank 2 after T time in the y = Ceiling(1.9) + 1 = 3thdraining process, it indicates that the y = Ceiling(1.9) + 1 = 3thdraining process has completely drained the rinsing water in the washing chamber 1, further indicating that there is no or a small amount of foam in the rinsing water, C21 (the space occupied by the foam) + C22 (the space occupied by the liquid) < C2 (the space of the sewage tank 2), and the obtained y = Ceiling(1.9) + 1 = 3 is recorded.

[0086] S432: If t0≤ T, i.e., the probe 3 can simultaneously detect the liquid in the sewage tank 2 within T time in the y = Ceiling(1.9) + 1 = 3thdraining process, it indicates that there is still a large amount of liquid in the washing chamber 1, and the air in the sewage tank 2 needs to be continuously drained.

[0087] S44: The air in the sewage tank 2 is continuously drained until the probe 3 cannot simultaneously detect the liquid in the sewage tank 2 after T time, i.e., the rinsing liquid in the washing chamber 1 is completely drained, the obtained y is recorded, y > Ceiling(1.9) + 1 = 3, which indicates that the number of times required to completely drain the rinsing water in the washing chamber 1 is greater than 3, and the number of rinsing times is increased; i.e., in the ythdraining process after step S43, y > Ceiling(n) + 1, i.e., y > Y; further indicating that there is still a large amount of foam in the rinsing water, and the number of rinsing times is increased.

[0088] S5: The actual number y is compared with the set number Y, and it is determined whether the washing object is rinsed clean.

[0089] S51: If y ≤ Y, the washing object is rinsed clean.

[0090] S52: If y > Y, the washing object is not rinsed clean.

[0091] In step S52, if it is determined that the washing object is not rinsed clean, the steps S1-S5 are repeated to perform rinsing again until y < Y in step S42 or y = Y in step S43 appears.

[0092] It should be noted that the maximum number of rinsing times is set to M, and if the actual number of rinsing times m > M, a fault alarm is performed to avoid endless rinsing and ensure the cleaning time.

[0093] The present application is not limited to the foregoing specific embodiments. The present application extends to any new feature or any new combination disclosed in the specification, and any new method or process step or any new combination disclosed.
