[0002] With the development of science and technology, more and more intelligent devices have entered people's lives. For example, washing machines that can automatically dispense detergent have brought great convenience to people.

[0003] In related art, to facilitate cleaning or replacement of detergent boxes, detergent is often placed in a replaceable container similar to toothpaste. When detergent needs to be added, a pump draws the detergent from the container into a diversion trough, where it flows into the clothing receiving chamber, achieving automatic detergent dispensing. Typically, a corresponding detection device (such as a probe) can also detect the resistance of the liquid in the diversion trough to determine whether the detergent is exhausted.

[0004] However, when the detergent is about to run out, the detergent drawn into the diversion groove will contain a large amount of conductive foam. The solutions of the related art often cause the resistance value read by the detection device to be inaccurate due to the conductivity of the foam, which in turn leads to the problem of being unable to accurately determine the remaining detergent.

[0045] In order to more clearly understand the above-mentioned objectives, features and advantages of the present disclosure, the scheme of the present disclosure will be further described below. It should be noted that the embodiments of the present disclosure and the features therein can be combined with each other in the absence of conflict.

[0046] In the following description, many specific details are set forth to facilitate a full understanding of the present disclosure, but the present disclosure may also be implemented in other ways different from those described herein; it is obvious that the embodiments in the specification are only part of the embodiments of the present disclosure, rather than all of the embodiments.

[0047] Usually, in order to conveniently clean or replace the detergent box, the detergent is often placed in a replaceable container similar to toothpaste. When the detergent needs to be added, the detergent is pumped from the container to the guide groove by a liquid pump, and the detergent can flow from the guide groove to the clothing storage cavity to realize the automatic addition of the detergent. Generally, the resistance of the liquid in the guide groove can also be detected by a corresponding detection device (such as a probe) to determine whether the detergent is used up. However, when the detergent is about to run out, the detergent drawn into the guide groove will carry a large amount of conductive foam. The solutions of the related art often cause the resistance value read by the detection device to be inaccurate due to the conductivity of the foam, which leads to the problem of being unable to accurately determine the remaining detergent.

[0048] To this end, the embodiments of the present disclosure provide a detergent detection method, a clothing processing device, and a storage medium. By adding detergent and introducing water into the detergent flow area where the detergent measuring device is located, the method determines whether the detergent is low based on the detection value of the detergent measuring device. The water flow can flush the detergent flow area to eliminate foam, ensuring that the detergent measuring device can accurately detect detergent parameters, thereby improving the problem of being unable to accurately determine the remaining detergent amount due to the presence of foam in the extracted detergent.

[0049] The detergent detection method provided in the embodiment of the present disclosure can be applied to the clothing processing device. Specifically, the corresponding steps are performed by a processing module in the clothing processing device having processing, control, calculation and other functions. The embodiment of the present disclosure does not limit this.

[0050] In some embodiments, the clothes processing device may further include a clothes accommodating cavity for accommodating clothes. When adding detergent, the detergent needs to be added to the clothes accommodating cavity through a corresponding channel.

[0051] The laundry processing device can be any washing machine with a washing function, for example, a pulsator washing machine or a drum washing machine. Furthermore, the laundry processing device can dispense detergent using a replaceable container or by adding detergent to a fixed container. It is sufficient that the laundry processing device can dispense detergent and includes a detergent flow area for allowing detergent to flow into the laundry accommodating cavity. This disclosure is not limited to this.

[0052] It is understandable that the clothing processing device may also include other components for realizing any possible clothing processing function or other functions related to clothing processing, such as motors, clutches, transmission belts, power supply devices, sensors, display devices, input devices and other components, which are not limited in the embodiments of the present disclosure.

[0053] The detergent detection method provided by the embodiments of the present disclosure is exemplarily described below with reference to the accompanying drawings.

[0054] For example, Figure 1 This is a flow chart of a detergent detection method provided by the present disclosure, which can be executed by the processing module in the above-mentioned clothing processing device. Figure 1 , the detergent detection method provided by the embodiment of the present disclosure may include:

[0055] Step 101: Add detergent and add water to the detergent flow area where the detergent measuring device is located.

[0056] The detergent measuring device is used to detect detergent parameters in the area where the detergent flows.

[0057] In this embodiment, the detergent may refer to a washing liquid used to clean dirt on textiles such as clothes or non-textiles, or it may refer to a care liquid used to eliminate static electricity on textiles such as clothes or non-textiles. This disclosed embodiment does not limit this.

[0058] In this embodiment, the detergent parameter may refer to a parameter that can characterize the amount of detergent remaining in the area where the detergent flows. For example, the detergent parameter may include at least one of the following: resistance, voltage, etc.

[0059] The detergent measuring device may be any possible detection device, such as a probe for detecting voltage or resistance, or a corresponding sensor, which is not limited in the embodiments of the present disclosure.

[0060] In this embodiment, the detergent flow area may refer to a structure such as a pipe or a diversion groove through which the detergent flows when the detergent is dispensed from the detergent box or replaceable container into the clothing storage cavity. It may also refer to the liquid outlet of the detergent box or replaceable container. This disclosure is not limited to this.

[0061] Exemplarily, the detergent box or replaceable container in the clothing processing device can be located directly above the clothing accommodating cavity. When the liquid outlet of the detergent box or the replaceable container is opened, the detergent in the detergent box or the replaceable container can be poured into the clothing accommodating cavity under the action of gravity.

[0062] In this case, the detergent measuring device can be arranged at the liquid outlet of the detergent box or the replaceable container.

[0063] For another example, if the detergent box or replaceable container in the clothing processing device is not located directly above the clothing accommodating cavity or the detergent needs to be guided to the clothing accommodating cavity through a structure such as a pipe or a guide groove, then the clothing processing device may further include a dispensing device for dispensing the detergent, so as to extract the detergent from the detergent box or the replaceable container to the detergent flow area, and then dispense it into the clothing accommodating cavity. For example, the dispensing device may be a liquid pump, an automatic squeezer, or the like. This disclosure does not limit this.

[0064] In this case, the detergent measuring device can be arranged at a corresponding position of the pipeline or the guide groove or other structures.

[0065] In a possible embodiment, the supplying of water to the detergent flow area where the detergent measuring device is located may refer to an operation of flushing the detergent flow area by discharging water into the detergent flow area. Specifically, the purpose of flushing may be achieved by providing a corresponding flushing device in the laundry processing device.

[0066] It is worth noting that if the detergent is about to run out or the remaining detergent is insufficient, a large amount of foam will be generated when the detergent is added, resulting in a large amount of foam in the area where the detergent flows through, and thus the detergent measuring device cannot accurately detect the detergent parameters of the detergent in the area where the detergent flows through, thus leading to the problem of being unable to accurately judge the remaining detergent.

[0067] It is worth noting that since foam will dissolve quickly when it comes into contact with water, after water is added to the area where the detergent flows to flush the area where the detergent flows, it can be ensured that there is no foam in the area where the detergent flows, thereby improving the accuracy and reliability of the detergent measuring device in detecting the detergent parameters, which is convenient for subsequent operations.

[0068] Step 102: Determine whether the detergent is short of liquid based on the detection value of the detergent measuring device.

[0069] In this embodiment, the detection value of the detergent measuring device may refer to a specific value of the detergent parameter detected by the detergent measuring device.

[0070] Generally, the detection value of the detergent measuring device may refer to the value detected by the detergent measuring device within a period of time. For example, the detection value of the detergent measuring device at least includes the value detected during the process of water entering the detergent flow area where the detergent measuring device is located.

[0071] Specifically, data analysis can be performed on the detection value of the detergent measuring device based on a corresponding analysis algorithm to determine whether the detergent is lacking liquid. Alternatively, whether the detergent is lacking liquid can be determined by determining whether the detection value of the detergent measuring device meets corresponding preset conditions. This embodiment of the present disclosure is not limited to this.

[0072] In this embodiment, the preset condition can be set by relevant technical personnel based on actual needs. For example, the preset condition can be that the detection value of the detergent measuring device is greater than or equal to a certain threshold. If the preset condition is met, it can be determined that the detergent is in a sufficient liquid state, that is, there is no shortage of liquid. Otherwise, it can be determined that the detergent is in a shortage of liquid.

[0073] It is worth noting that, since water has already been introduced into the detergent flow area where the detergent measuring device is located in the above steps to flush the detergent flow area and eliminate any foam that may be present in the detergent flow area, the effect of foam that may be present when the detergent is about to run out or is insufficient can be eliminated. This ensures that the detection value of the detergent measuring device is accurate, thereby ensuring the accuracy of the determination of whether the detergent is insufficient.

[0074] In the embodiment of the present disclosure, detergent is added and water is introduced into the detergent flow area where the detergent measuring device is located. It is determined whether the detergent is lacking liquid based on the detection value of the detergent measuring device.

[0075] Since foam dissolves quickly upon contact with water, any foam present in the detergent flow area can be eliminated by flushing the area with water. This eliminates the effect of foam that may be present when the detergent is about to run out or is insufficient. This improves the accuracy and reliability of the detergent measuring device in detecting detergent parameters, thereby ensuring the accuracy of determining whether detergent is insufficient.

[0076] In this way, the area through which the detergent flows can be flushed with water to eliminate foam, ensuring that the detergent measuring device can accurately detect the parameters of the detergent, thereby improving the problem of being unable to accurately judge the remaining detergent amount due to the presence of foam in the extracted detergent.

[0077] Furthermore, even if there is no foam in the area where the detergent flows, when the detergent is about to run out or is running low, the amount of detergent delivered to the area where the detergent flows will be less than the amount delivered when the detergent is sufficiently liquid. Since a smaller amount of detergent is more easily washed away by the water flow, the detection value of the detergent measuring device will also change significantly. Therefore, the detergent detection method provided by the embodiments of the present disclosure can achieve the effect of accurately and reliably determining the remaining detergent amount when the detergent is about to run out or is running low.

[0078] In one possible implementation, water is introduced into the detergent flow area where the detergent measuring device is located, including:

[0079] Water is continuously fed into the detergent flow area where the detergent metering device is located.

[0080] In this embodiment, the continuous water inflow operation may refer to starting to inflow water into the detergent flow area after the detergent is added to the detergent flow area, and continuing until the detergent is added or the detergent measuring device completes detection. This disclosure does not limit this.

[0081] Exemplarily, the clothes processing device may include a water inlet device, which may be a water inlet valve, a water pump, or the like, and the embodiments of the present disclosure are not limited thereto.

[0082] For example, when water is continuously supplied to the area through which detergent flows, the following method can be used: after the detergent is added, the water supply device is controlled to be powered on to start supplying water to the area through which detergent flows. When the detergent is added, the water supply device is controlled to be powered off to stop supplying water to the area through which detergent flows.

[0083] It is worth noting that different types of detergents have different characteristics, such as some detergents have higher viscosities and some detergents have lower viscosities. Generally, detergents with higher viscosities are less easily washed away by the water flow, while detergents with lower viscosities are more easily washed away by the water flow. To avoid the problem of low-viscosity detergents being quickly washed away due to continuous water inflow, water can be continuously fed into the detergent flow area where the detergent measuring device is located when the viscosity of the detergent is higher.

[0084] Since the shapes and / or inclinations of the detergent flow areas of different clothing processing devices are different, for example, the detergent flow areas of some clothing processing devices are straight or rectangular, while the detergent flow areas of some processing devices are S-shaped or right-angled.

[0085] The water flow rate in the detergent flow area with a straight or rectangular shape is relatively fast, while the water flow rate in the detergent flow area with an S-shaped or right-angled shape is relatively slow. In addition, the greater the slope of the detergent flow area, the higher the water flow rate.

[0086] To avoid the problem of detergent being quickly washed away due to the high flow rate of continuous water inflow, water can be continuously introduced into the detergent flow area where the detergent measuring device is located when the detergent flow area is S-shaped or right-angled, and / or the slope of the detergent flow area is relatively small. This is not limited in the present embodiment.

[0087] It is worth noting that continuously supplying water to the detergent flow area where the detergent measuring device is located can provide a large amount of water, thereby ensuring that any foam that may exist in the detergent flow area can be quickly eliminated. This can improve the efficiency of obtaining the detection value of the detergent measuring device and thus improve the efficiency of detecting the remaining detergent amount.

[0088] In one possible implementation, water is introduced into the detergent flow area where the detergent measuring device is located, including:

[0089] Water is intermittently supplied to the detergent flow area where the detergent measuring device is located.

[0090] In this embodiment, the intermittent water supply operation means that during the process from the start of adding the detergent to the completion of adding, there is at least a period of time when water is not supplied to the area through which the detergent flows.

[0091] Specifically, intermittently supplying water to the detergent flow area where the detergent measuring device is located may include:

[0092] The water inlet device is controlled to perform at least one opening action and at least one closing action according to preset action parameters.

[0093] The preset action parameter is determined by at least one of the following: the inclination of the area through which the detergent flows, the structure of the area through which the detergent flows, the viscosity of the washing solvent, and the material of the detergent measuring device.

[0094] The preset action parameters include at least: the number of times the water inlet device needs to be opened and closed, the time of opening the water inlet device, and the time of closing the water inlet device.

[0095] Specifically, based on the opening action of the water inlet device, water can be fed into the detergent flow area. Based on the closing action of the water inlet device, water can be stopped from being fed into the detergent flow area.

[0096] Furthermore, at least one of the time interval between two adjacent water inflows, the duration of each water inflow, and the water inflow speed can be controlled based on the structural parameters of the detergent flow area where the detergent measuring device is located and / or the detergent viscosity.

[0097] The structural parameters of the detergent flow area may include the shape of the detergent flow area and / or the degree of inclination (ie, the slope of the detergent flow area).

[0098] For example, the time interval between two adjacent water inflows is negatively correlated with the viscosity of the detergent. The duration of each water inflow is positively correlated with the viscosity of the detergent. The water inflow speed is also positively correlated with the viscosity of the detergent.

[0099] Furthermore, the structural parameters include the slope of the detergent flow area where the detergent measuring device is located. The time interval between two adjacent water inflows is positively correlated with the slope. The duration of each water inflow is negatively correlated with the slope. The water inflow speed is also negatively correlated with the slope.

[0100] That is, the greater the inclination of the detergent flow area, the longer the time interval between two adjacent water inflows can be set, the shorter the duration of each water inflow can be set, and / or the slower the water inflow speed can be set. The smaller the detergent flow area, the shorter the time interval between two adjacent water inflows can be set, the longer the duration of each water inflow can be set, and / or the faster the water inflow speed can be set.

[0101] For another example, for a detergent flow area in a straight line or rectangular shape, the time interval between two adjacent water inflows can be set shorter, the duration of each water inflow can be set longer, and / or the water inflow speed can be set faster. For a detergent flow area in a straight line or rectangular shape, the time interval between two adjacent water inflows can be set longer, the duration of each water inflow can be set shorter, and / or the water inflow speed can be set slower.

[0102] In addition, the parameters of the interval water inflow can also be adjusted according to the material of the detergent measuring device. For example, if the detergent measuring device is a probe, the easier it is for the material of the probe to adhere to the detergent, the shorter the time interval between two adjacent water inflows can be set, the longer the duration of each water inflow can be set, and / or the faster the water inflow speed can be set.

[0103] The above examples are merely intended to illustrate the relationship between the structural parameters of the detergent flow area and / or detergent viscosity and the parameters of the interval water inflow. They do not necessarily limit the time interval between two adjacent water inflows, the duration of each water inflow, and / or the water inflow rate to the above-described method. The above-described time interval between two adjacent water inflows, the duration of each water inflow, and / or the water inflow rate can be flexibly adjusted according to actual needs, and the presently disclosed embodiments do not limit this.

[0104] It is worth noting that, as mentioned above, different types of detergents have different characteristics, and the shapes and / or inclinations of the detergent flow areas of different laundry processing equipment also vary. However, by using the method of intermittently supplying water to the detergent flow area, the parameters of the intermittent water supply can be flexibly adjusted according to the structural parameters of the detergent flow area and / or the viscosity of the detergent. In this way, water can be adaptively selected to supply water to the detergent flow area in a manner suitable for the laundry processing equipment, thereby improving the practicality of the detergent detection method.

[0105] In one possible implementation, Figure 1 Based on Figure 2 , determining whether the detergent is lacking based on the detection value of the detergent measuring device, including:

[0106] Step 1021: Acquire a detection value of the detergent measuring device during the process of water entering the detergent flow area where the detergent measuring device is located.

[0107] In this embodiment, the duration of water entering the detergent flow area where the detergent measuring device is located may refer to the first time period.

[0108] It is worth noting that the detection value of the detergent measuring device obtained in step 1021 is the detection value detected by the detergent measuring device during the first time period. In other words, the detection value of the detergent measuring device can be not just a single value, but can be a data pair of multiple values and time detected by the detergent measuring device, which is not limited in the present embodiment.

[0109] Step 1022: Determine whether the detergent is lacking liquid based on the rate of change of the detection value.

[0110] In this embodiment, the rate of change of the detection value can be used to characterize the speed of change of the detection value detected by the detergent measuring device during the water inflow process of the detergent flowing through the area, or the amplitude of change of the detection value detected by the detergent measuring device within the first time.

[0111] The rate of change of the detection value can also be used to indicate the amount of foam in the area where the detergent flows.

[0112] It is worth noting that, since the foam that may exist in the detergent flow area has been dissipated by water during the process of water entering the detergent flow area where the detergent measuring device is located, the detection value before the foam in the detergent flow area dissipates and the detection value after the foam dissipates will have a large change.

[0113] Therefore, by reflecting the change amplitude or change speed of the detection value in the first period through the change rate, it is possible to determine whether foam dissipation has occurred in the first period. In this way, it is possible to accurately and reliably determine whether the detergent is lacking.

[0114] In one possible embodiment, based on the execution of step 1021, a standby detection value of the detergent measuring device in the second time period may also be obtained.

[0115] In this embodiment, the second time period may be a period of time after water enters the detergent flow area where the detergent measuring device is located. Furthermore, the standby detection value may also be a data pair of a plurality of values and times detected by the detergent measuring device during the second time period.

[0116] Then, step 1022 may specifically determine whether the detergent is short of liquid based on the rate of change of the detection value and / or the rate of change of the standby detection value.

[0117] Among them, the change rate of the standby detection value can be used to characterize the speed of change of the detection value detected by the detergent measuring device within a period of time after the water enters the detergent flow area, or the change amplitude of the detection value detected by the detergent measuring device within the second time period.

[0118] It is worth noting that if detergent is no longer added after water inflow is completed, the standby detection value during the second period will not change. Therefore, the method of continuing to obtain the standby detection value of the detergent measuring device during the second period can be applicable to the scenario where detergent is continued to be added after water inflow.

[0119] In this way, the accuracy of determining whether the detergent is lacking liquid can be further improved through the dual verification of the change rate of the detection value and the change rate of the standby detection value.

[0120] In one possible implementation, Figure 2 Based on Figure 3 , determining whether the detergent is lacking liquid based on the change rate of the detection value, including:

[0121] Step 1023: Based on the fact that the change in the detection value within the preset time is greater than or equal to a preset threshold, it is determined that the detergent is lacking liquid.

[0122] In this embodiment, the preset time may refer to any period of time within the first period, and the duration of the preset time is less than or equal to the duration of the first period. The preset threshold may be set by relevant technical personnel according to actual needs.

[0123] Generally, if the variation of the detection value within a preset time is greater than or equal to the preset threshold, it may indicate that the resistance, voltage and other parameters detected by the detergent measuring device have changed significantly within a short period of time.

[0124] Specifically, if the rate of change of the detection value detected at any time during the first period is greater than or equal to the preset threshold, it can be determined that the detergent is lacking liquid. Alternatively, if the amount of change of the detection value within the preset time during the first period is greater than or equal to the preset threshold, it can be determined that the detergent is lacking liquid. This embodiment of the present disclosure is not limited to this.

[0125] It is worth noting that, due to the certain viscosity of the detergent, it will not be washed away quickly by the water flow, and the detection value will not suddenly increase or decrease, that is, the change in the detection value within the preset time will not be large. However, under the flushing of the water flow, the foam will dissipate quickly, and the detection value will suddenly change, that is, the change in the detection value within the preset time will be relatively large.

[0126] Therefore, if the variation of the detection value within the preset time is greater than or equal to the preset threshold, it can be determined that there is a lot of foam in the area where the detergent flows through. In this way, it can be accurately determined whether the detergent is lacking liquid.

[0127] Furthermore, when the standby detection value in the second period is obtained, it can also be determined whether the change in the standby detection value obtained by the detergent measuring device in the second period within a specific time is greater than or equal to a preset threshold.

[0128] In this embodiment, the specific time may refer to any period of time within the second time period, and the duration of the specific time is less than or equal to the duration of the second time period.

[0129] Specifically, if the standby detection value obtained in the second time period changes within a specific time period by an amount greater than or equal to the preset threshold, it can be determined that the detergent is lacking liquid.

[0130] In this way, the accuracy of determining whether the detergent is lacking liquid can be further improved through the dual verification of the change in the detection value within the preset time and the change in the standby detection value within a specific time.

[0131] In one possible implementation, Figure 1 Based on Figure 4 After obtaining the detection value of the detergent measuring device during the process of water entering the detergent flow area where the detergent measuring device is located, the method further includes:

[0132] Step 1024: Based on the consistency between the change curve of the detection value and the change curve of the detergent liquid shortage detection value, it is determined that the detergent liquid is insufficient.

[0133] In this embodiment, the detection value variation curve is used to characterize the variation of the washing liquid parameter detected in the detergent flow area during the first period. In addition, the detection value variation curve can also indicate the amount of detergent foam in the detergent flow area.

[0134] The detergent liquid shortage detection value change curve can be obtained by relevant technicians through multiple experiments, and is specifically used to represent the change curve of the detection value measured by the detergent measuring device when the detergent is in a liquid shortage state when the detergent is added and water enters the detergent flow area. The detergent liquid shortage detection value change curve corresponds to the structural parameters of the detergent flow area in the clothes processing device and / or the detergent viscosity.

[0135] Specifically, the detergent liquid shortage detection value change curve can be obtained by using the same water inlet method and water inlet parameters as the above step 101, and ensuring that the time for obtaining the detergent liquid shortage detection value is also the same as the time for obtaining the detection value in the above step 102.

[0136] Illustratively, the consistency between the detection value change curve and the detergent liquid shortage detection value change curve may refer to any of the following: the shape of the detection value change curve is similar to or identical to the shape of the detergent liquid shortage detection value change curve, the numerical values indicated by characteristic points in the detection value change curve are similar to or identical to the numerical values indicated by characteristic points in the detergent liquid shortage detection value change curve, the numerical values corresponding to the detection value change curve and the detergent liquid shortage detection value change curve at each moment are both within an error range, the slopes of the detection value change curve and the detergent liquid shortage detection value change curve at each moment are both within an error range, etc. The presently disclosed embodiments are not limited to this.

[0137] For example, see Figure 5 , Figure 5 (a) in the figure shows a detergent liquid shortage detection value variation curve q1, a detection value variation curve c1 and a detection value variation curve c2.

[0138] from Figure 5 As can be seen from (a) in the figure, the horizontal axis of the coordinate system is the time axis t and the vertical axis is the value axis s, that is, the detergent liquid shortage detection value change curve q1, the detection value change curve c1 and the detection value change curve c2 all represent the relationship between the detection value and time.

[0139] The time period from time 0 to time t1 may refer to the first time period, and the change curves c1 and c2 may respectively indicate changes in the detection value of the detergent measuring device when water enters the detergent flow area. The detergent liquid shortage detection value change curve q1 may represent changes in the detection value of the detergent measuring device when water enters the detergent flow area when detergent liquid is insufficient.

[0140] Specifically, the detergent liquid shortage detection value change curve q1 has an interval with a significant decrease in value within the first period, that is, the rate of change of the detergent liquid shortage detection value change curve q1 within the first period is relatively large. The change curve c1 has a relatively slow downward trend within the first period, that is, the rate of change of the change curve c1 within the first period is relatively small. The change curve c2 also has an interval with a significant decrease in value within the first period, that is, the rate of change of the change curve c2 within the first period is relatively large.

[0141] Then, it can be determined that the change curve c1 is inconsistent with the detergent liquid shortage detection value change curve q1, and further it can be determined that the operating condition corresponding to the change curve c1 is that the detergent is not lacking liquid. Correspondingly, it can be determined that the change curve c2 is consistent with the detergent liquid shortage detection value change curve q1, and further it can be determined that the operating condition corresponding to the change curve c2 is that the detergent is lacking liquid.

[0142] Figure 5 (b) in the figure shows another detergent liquid shortage detection value change curve q2, the detection value change curve c3 and the detection value change curve c4.

[0143] from Figure 5 As can be seen from (b) in the figure, the detergent liquid shortage detection value variation curve q2, the detection value variation curve c3 and the detection value variation curve c4 also represent the relationship between the detection value and time.

[0144] Here, time t1 to time t2 may refer to the aforementioned second time period. Thus, the variation curves c1 and c2 may indicate not only the change in the detection value during the inflow of water into the detergent flow area where the detergent measuring device is located, but also the change in the detection value over a period of time after the inflow of water into the detergent flow area where the detergent measuring device is located. The detergent liquid shortage detection value variation curve q2 may represent the change in the detection value during the inflow of water into the detergent flow area where the detergent measuring device is located, and over a period of time after the inflow of water into the detergent flow area where the detergent measuring device is located, in the case of detergent shortage.

[0145] Specifically, the detergent liquid shortage detection value variation curve q2 has a significant decreasing interval in the first period, and a significant increasing interval in the second period. In other words, the detergent liquid shortage detection value variation curve q1 has a relatively large changing rate interval in the first period and the second period, respectively.

[0146] Curve c3 shows a relatively slow downward trend in the first period and a relatively slow upward trend in the second period. That is, curve c1 has a relatively low rate of change in both the first and second periods. Curve c4, on the other hand, also has a significant downward trend in the first period and a significant upward trend in the second period. That is, curve c4 has a relatively high rate of change in both the first and second periods.

[0147] Then, it can be determined that the variation curve c3 is inconsistent with the detergent liquid shortage detection value variation curve q2, and further, it can be determined that the operating condition corresponding to the variation curve c3 is that the detergent is not insufficient. Correspondingly, it can be determined that the variation curve c4 is consistent with the detergent liquid shortage detection value variation curve q2, and further, it can be determined that the operating condition corresponding to the variation curve c4 is that the detergent is insufficient.

[0148] For another example, the variation curve of the detection value may be obtained by performing data analysis on the detection value of the detergent measuring device using a corresponding waveform analysis algorithm.

[0149] Specifically, data analysis may be performed on the first time period and the detection values obtained by the detergent measuring device during the first time period based on the waveform analysis algorithm to obtain a target characteristic function.

[0150] For example, the waveform analysis algorithm may be a Lagrange linear interpolation method, or any other possible algorithm.

[0151] A variation curve of the detection values acquired during the first time period is determined according to the target characteristic function.

[0152] It is worth noting that the detection value of the detergent measuring device is fitted into a change curve of the detection value and compared with the change curve of the detergent liquid shortage detection value. This can greatly reduce the computing pressure of the clothing processing equipment, enable the method to be applied to low-computing power equipment, and thus improve the versatility and practicality of the method.

[0153] Furthermore, when a backup detection value is obtained within the second time period, data analysis can be performed on the detection value obtained by the first time period and the detergent measuring device within the first time period, as well as the backup detection value obtained by the second time period and the detergent measuring device within the second time period based on the waveform analysis algorithm to obtain a new target characteristic function.

[0154] Furthermore, the variation curves of the detection values obtained in the first time period and the second time period can be determined according to the new target characteristic function.

[0155] In this case, the detergent liquid shortage detection value variation curve also needs to include the detergent liquid shortage detection value detected within a period of time after the water inflow is completed.

[0156] In this way, the accuracy of determining whether the detergent is lacking liquid can be further improved through the dual verification of the change rate of the detection value and the change rate of the standby detection value.

[0157] In a possible implementation, the method may further include:

[0158] Based on the lack of detergent, a prompt message is output.

[0159] In this embodiment, the prompt information can be any possible form of information such as sound, light, text, etc. The prompt information can be used to remind the user that the detergent is low and needs to be refilled in the detergent box. This embodiment of the present disclosure is not limited to this.

[0160] Furthermore, in a case where the clothing processing device further includes a communication device, the prompt information can also be output to other terminal devices or servers connected to the clothing processing device through the communication device, which is not limited in this embodiment of the present disclosure.

[0161] The communication device may be any possible device such as an Internet of Things device, a Bluetooth device, an infrared device, a WI-FI device, etc., and the embodiments of the present disclosure do not limit this.

[0162] In this way, the user can be informed promptly and reliably when the detergent is running low, thereby improving the practicality of the detergent detection method provided by the embodiment of the present disclosure.

[0163] As a possible approach, in the detergent detection method provided in the embodiment of the present disclosure, the above-mentioned detergent liquid shortage detection value change curve and / or the above-mentioned preset threshold value can also be obtained in real time from the corresponding server through the communication device, and the embodiment of the present disclosure does not limit this.

[0164] In one possible implementation, before water is introduced into the detergent flow area where the detergent measuring device is located, the method may further include:

[0165] The slope of the area through which the detergent flows, the structure of the area through which the detergent flows, the viscosity of the detergent and / or the material of the detergent measuring device are obtained.

[0166] For example, if the laundry processing device includes the aforementioned communication device and is connected to a server via the communication device, then the communication device can send a request to the server, and receive and parse the data sent by the server to obtain information such as the inclination of the detergent flow area, the structure of the detergent flow area, the viscosity of the detergent, and / or the material of the detergent measuring device. Alternatively, the aforementioned information can be read from the memory of the laundry processing device, although this is not limited in the present embodiment.

[0167] It is worth noting that, since the time interval between two adjacent water inflows, the duration of each water inflow, and / or the water inflow speed can be controlled based on the structural parameters of the detergent flow area where the detergent measuring device is located and / or the detergent viscosity, the corresponding information can be obtained before water inflow so that water can be introduced into the detergent flow area in a more reasonable manner. In this way, it is possible to avoid the problem of excessive water inflow or excessive water inflow time causing the detergent in the detergent flow area to be washed away too quickly, or the problem of insufficient water inflow or excessive water inflow time causing the inability to completely eliminate possible foam in the detergent flow area.

[0168] In this way, the accuracy and reliability of the detergent measuring device in detecting the detergent parameters can be improved.

[0169] In order to better illustrate the position and connection relationship between the detergent box, the detergent measuring device, the detergent flow area, and the clothing accommodating cavity in the above-mentioned clothing processing device, the embodiment of the present disclosure also provides a structural schematic diagram of the clothing processing device, see Figure 6 .

[0170] like Figure 6 As shown, the laundry processing device may include a detergent box H, a detergent flow area Q, a laundry accommodating cavity R, a water inlet device J, and several probes T, and the detergent box H is provided with a liquid outlet C.

[0171] The detergent box H is used to hold or store detergent. When the detergent needs to be added, the detergent can be caused to flow from the liquid outlet C to the detergent flow area Q in any possible manner. For example, the detergent can be pumped from the detergent box H to the detergent flow area Q by a liquid pump, or the detergent box can be pressurized to squeeze the detergent from the liquid outlet C to the detergent flow area Q. This is not limited in the present embodiment.

[0172] The water inlet device J can be a water inlet valve or a water pump. When the water inlet device J is powered on, water can be fed into the detergent flow area Q.

[0173] Probe T can be a measuring device for detecting voltage or resistance. When detergent is placed in the detergent flow area Q, probe T can contact the detergent to measure the resistance or voltage of the detergent. If the detergent contains foam, which is generally conductive, probe T can also measure the resistance or voltage of the detergent and foam in the detergent flow area Q.

[0174] The probe T may be further connected to the aforementioned processing module to output the measured detection value to the processing module.

[0175] In addition, if Figure 6 As shown, since the liquid outlet C of the detergent box H is positioned higher than the clothing accommodating chamber R, and the detergent flow-through area Q is connected between the detergent box H and the clothing accommodating chamber R, after the detergent is added to the detergent flow-through area Q, the detergent can flow along the detergent flow-through area Q toward the clothing accommodating chamber R. Furthermore, when the water inlet device J introduces water into the detergent flow-through area Q, the water flow flushes the detergent in the detergent flow-through area Q, and the water flow and detergent also flow toward the clothing accommodating chamber R. In this way, it is ensured that the detergent can be properly added to the clothing accommodating chamber R while the detergent flow-through area Q is flushed.

[0176] It should be noted that Figure 6 The clothes processing device shown is only an example and does not mean that the detergent detection method provided by the embodiment of the present disclosure can only be applied to such clothes processing devices.
