Description

Technical Field

[0001] The present invention belongs to the technical field of mechanical equipment, and in particular, relates to a method for processing water quality information of a washing machine and a washing machine. Background Art

[0002] At present, most washing machines on the market have a variety of programs and complicated functions, which are dizzying, including washing programs, rinsing programs and spin programs. However, users do not know the best washing / rinsing times, washing / rinsing time, washing / rinsing water level when washing / rinsing, and cannot make real-time adjustments. They often only select a few specific default programs for washing and rinsing for a long time.

[0003] Therefore, washing machines that detect the turbidity value of the washing water inside the washing machine and control the washing machine to select the corresponding washing / rinsing program have appeared on the market. That is, the washing machine selects the corresponding washing / rinsing program according to different turbidity values. For example, if the turbidity value is large, the selected washing / rinsing program will run for a longer time; if the turbidity value is small, the selected washing / rinsing program will run for a shorter time.

[0004] At present, washing machines are equipped with a turbidity detector to detect the turbidity of washing water. The turbidity detector is generally directly installed inside the washing machine. The turbidity detector is prone to accumulate a lot of stains during long-term use and is difficult to clean, resulting in inaccurate turbidity values ​​of the washing water detected.

[0005] Alternatively, the washing machine is equipped with a separate water quality information detection device. When the washing machine is turned on, the water quality information detection device is placed in the washing water to detect the washing water. When not in use, the water quality information detection device can be taken out and cleaned. However, this water quality information detection device has the following problems:

[0006] 1. When the water quality information detection device placed in the washing water is low on power, the detected water quality information will be inaccurate.

[0007] Second, the water quality information detection device is held up by the clothes and is not submerged in the washing water, causing the water quality information detection device to not work normally and unable to detect the water quality information of the washing water.

[0008] 3. The sensor of the water quality information detection device used to contact the washing water and detect the water quality information is covered by the foam in the washing water, resulting in inaccurate water quality information detected.

[0009] In view of this, the present invention is proposed. Summary of the invention

[0010] The purpose of the present invention is to overcome the problem that the existing washing machine is affected by the water quality detection module and the detected water quality information is inaccurate, and to provide a water quality information processing method for a washing machine so that the output water quality information is more accurate.

[0011] In order to solve the above technical problems, the basic concept of the technical solution adopted by the present invention is: a water quality information processing method for a washing machine, the washing machine includes a water quality detection module, which is used to detect the water quality information of washing water, and the water quality detection module determines whether to correct the output water quality information value according to the change in water quality information or the remaining power / working status of the water quality detection module.

[0012] Furthermore, the remaining power value C0 of the water quality detection module is preset.

[0013] When the remaining power C of the monitored water quality detection module is less than or equal to C0, the water quality detection module is controlled to correct the detected water quality information and output the corrected water quality information;

[0014] When the monitored remaining power of the water quality detection module C>C0, the water quality detection module is controlled to directly output the detected water quality information.

[0015] Furthermore, the water quality detection module establishes a corresponding sample water quality information parameter matrix according to the water quality information values ​​corresponding to different remaining power levels;

[0016] When the monitored remaining power C of the water quality detection module is less than or equal to C0, the detected water quality information is corrected according to the water quality parameter matrix corresponding to the remaining power, and the water quality detection module is controlled to output the corrected water quality information.

[0017] Furthermore, the water quality monitoring module includes a cloud server for correcting data.

[0018] When the monitored remaining power of the water quality detection module C≤C0, the cloud server is controlled to output the corrected water quality information according to the detected water quality information and the current remaining power.

[0019] Furthermore, the working state of the water quality detection module includes a normal state and an abnormal state.

[0020] When the detected water quality information S t = 0, the water quality detection module is judged to be in an abnormal state, and the water quality detection module is controlled to output the average value of the historical water quality information, or output the last water quality information S t-1 ;

[0021] When the detected water quality information S t When >0, it is determined that the water quality detection module is in a normal working state, and the water quality detection module is controlled to directly output the detected water quality information.

[0022] Furthermore, the water quality monitoring module includes a cloud server for fitting data.

[0023] When the detected water quality information S t = 0, the cloud server is controlled to adjust the current water quality information S according to the historical water quality information detected. t Perform data fitting and control the water quality detection module to output the fitted water quality information.

[0024] Furthermore, the water quality information difference ΔS0 is preset to obtain the currently detected water quality information S t The last water quality information S t-1 The difference between them is ΔS;

[0025] When the acquired difference ΔS≥ΔS0, the water quality detection module is controlled to correct the detected water quality information and output the corrected water quality information;

[0026] When the obtained difference ΔS<ΔS0, the water quality detection module is controlled to output the water quality information value S t .

[0027] Furthermore, the water quality monitoring module includes a cloud server,

[0028] When the difference ΔS≥ΔS0 is obtained, the cloud server calculates the current water quality information value S according to the historical water quality information value detected. t Perform data fitting and output the fitted water quality information;

[0029] Alternatively, the cloud server calculates and outputs the corrected water quality information based on the acquired difference ΔS.

[0030] Furthermore, when ΔS ≥ ΔS0, remove the current water quality information value S t , output the last water quality information value S t-1 ;

[0031] Alternatively, the water quality detection module establishes a corresponding sample water quality information value parameter matrix according to different ΔS, and when the obtained difference ΔS≥ΔS0, corrects the detected water quality information according to the water quality parameter matrix corresponding to the obtained difference ΔS, and outputs the corrected water quality information.

[0032] The present invention also provides a washing machine, which adopts the water quality information processing method of the washing machine.

[0033] After adopting the above technical scheme, the present invention has the following beneficial effects compared with the prior art.

[0034] 1. By determining whether to correct the output water quality information value according to the change in water quality information or the remaining power / working status of the water quality detection module, the output water quality information is not interfered by the water quality detection module itself, thereby ensuring the accuracy of the water quality information. The output water quality information can reflect the true state of the washing water. The washing / rinsing program of the washing machine is controlled according to the output water quality information. On the basis of ensuring that the clothes can be washed clean, the water and power consumption of the washing machine is saved, the working efficiency of the washing machine is improved, and the washing machine is more efficient, energy-saving, and environmentally friendly.

[0035] 2. By monitoring the remaining power of the water quality detection module, when the remaining power is lower than the preset remaining power value C0, it means that the power of the water quality detection module is insufficient, which will cause the detected water quality information to be inaccurate. By correcting the detected water quality information before output, the interference of insufficient remaining power of the water quality detection module on the water quality information is avoided, and the accuracy of the output water quality information is ensured.

[0036] 3. By correcting the water quality information value detected when the water quality detection module is in an abnormal working state, the interference of the water quality detection module in the abnormal state on the output water quality information is avoided, making the water quality information more accurate.

[0037] 4. By obtaining the water quality information difference ΔS, when ΔS is greater than the preset value ΔS0, it indicates that the currently detected water quality information S t The last water quality information S t-1 If the difference between them is large, the detected water quality information has mutated and is inaccurate. The current water quality information is corrected before output to ensure the accuracy of the water quality information.

DETAILED DESCRIPTION

[0047] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention but are not used to limit the scope of the present invention.

[0048] In the description of the present invention, it should be noted that the directions or positional relationships indicated by terms such as “upper”, “lower”, “front”, “back”, “left”, “right”, “vertical”, “inside” and “outside” are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0049] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0050] The present invention provides a control method for a washing machine. The washing machine in the present invention comprises a water quality detection module for detecting water quality information of washing water. The water quality information detection module comprises a water quality detection element, a communication module and a control module.

[0051] The water quality detection element is placed in the washing water to obtain the water quality information of the washing water. The water quality information is determined by the control module to determine whether it needs to be corrected; if it needs to be corrected, the corrected water quality information is sent to the communication module; if it does not need to be corrected, the detected water quality information is directly sent to the communication module.

[0052] The communication module is connected to the intelligent terminal of the washing machine for communication. The communication module feeds back the water quality information to the intelligent terminal of the washing machine, and the intelligent terminal of the washing machine controls the washing program / rinsing program of the washing machine according to the water quality information.

[0053] The water quality detection unit includes a TDS detection unit, a TOC detection unit, a turbidity detection unit, a detergent residue detection unit, etc., which are used to detect chemical residues in the washing water, the content of organic matter in the water, chromaticity, turbidity value, etc. Among them, the water quality information is calculated based on the chemical residues in the washing water, the content of organic matter in the water, chromaticity, and turbidity value. The range of water quality information is between 0-100. The larger the value of the water quality information, the dirtier the washing water.

[0054] The water quality detection module of the present invention has a power storage device to maintain the normal operation of the water quality monitoring module. When the power storage device of the water quality detection module has sufficient power, the normal operation of the water quality detection module can be guaranteed. When the power is insufficient, the water quality detection module cannot operate normally, resulting in inaccurate water quality information detected.

[0055] Specifically, when the power is insufficient, one or more of the TDS detection unit, TOC detection unit, turbidity detection unit, and detergent residue detection unit in the water quality detection element cannot be detected normally, resulting in inaccurate final water quality information.

[0056] Therefore, in the present invention, it is determined whether to correct the output water quality information value according to the remaining power of the monitored water quality detection module. If the remaining power is within the set threshold range, the control directly outputs the water quality information; if the remaining power is not within the threshold range, the water quality information is corrected and then output to ensure the accuracy of the water quality information.

[0057] Alternatively, in the present invention, whether to correct the output water quality information value is determined according to the working state of the water quality detection module. Specifically, the working state of the water quality detection module includes a normal working state and an abnormal working state.

[0058] When the water quality detection component is put into the washing water, it can work normally, and it is in a normal working state. When the water quality detection component is lifted up by the clothes and is not submerged in the washing water, the water quality detection module cannot work normally and cannot detect the water quality information of the washing water. It is in an abnormal working state.

[0059] In abnormal working conditions, the water quality information value needs to be corrected to avoid inaccurate output of water quality information, which causes clothes to be washed uncleanly.

[0060] Alternatively, the present invention determines whether to correct the output water quality information value based on the change in the water quality information. When the change in the water quality information exceeds the threshold range preset by the washing machine, it indicates that the water quality information has undergone a sudden change. That is, the water quality detection component may be covered by foam or insoluble matter in the washing water, and the water quality information of the washing water cannot be accurately detected, which ultimately leads to inaccurate water quality information values ​​being detected. At this time, the water quality detection module is controlled to correct the detected water quality information to ensure the accuracy of the water quality information.

[0061] By determining whether to correct the output water quality information value according to the change in water quality information or the remaining power / working status of the water quality detection module, the output water quality information is not interfered by the water quality detection module itself, thereby ensuring the accuracy of the water quality information.

[0062] The output water quality information can reflect the real state of the washing water, and the washing / rinsing program of the washing machine can be controlled according to the output water quality information. On the basis of ensuring that the clothes can be washed clean, the water and power consumption of the washing machine is saved, the working efficiency of the washing machine is improved, and the washing machine is more efficient, energy-saving and environmentally friendly.

[0063] As an embodiment of the present invention, Figure 1 and Figure 2 As shown, the washing machine is turned on, the water quality detection module is controlled to be turned on, and the water quality information is detected. The remaining power C0 and the working time t0 are preset. Among them, the working time t0 can be a fixed value; or, the working time t0 will change with the running time of the washing machine; if the working time of the washing machine is extended, t0 will increase to ensure that the water quality detection module is in a working state when the washing machine is washing / rinsing. The working time t0 is greater than or equal to the washing and rinsing time of the washing machine.

[0064] The remaining power of the water quality detection module is monitored. When the monitored remaining power of the water quality detection module C≤C0, the water quality detection module is controlled to correct the detected water quality information and output the corrected water quality information.

[0065] When the monitored remaining power of the water quality detection module C>C0, the water quality detection module is controlled to directly output the detected water quality information.

[0066] The above steps are repeated. When the working time t≥t0, it indicates that the washing / rinsing of the washing machine is completed, and the water quality detection module is controlled to stop working.

[0067] In this embodiment, when the remaining power of the water quality detection module C≤C0, it indicates that the power of the water quality detection module is low and cannot guarantee its normal operation, which will lead to inaccurate water quality information. Therefore, by correcting the water quality information before outputting it, the output water quality information is more accurate.

[0068] By outputting water quality information to control the washing / rinsing program of the washing machine, it is more conducive to improving the cleanliness of clothes, saving water and improving the efficiency of the washing machine.

[0069] When the remaining power of the water quality detection module C>C0, it indicates that the water quality detection module can operate normally. After the detection is completed, the water quality detection module can be taken out of the washing water and cleaned for long-term use to ensure the accuracy of the water quality information of the washing water.

[0070] As an implementation method of this embodiment, the water quality detection module establishes a corresponding sample water quality information parameter matrix according to the water quality information values ​​corresponding to different remaining power levels;

[0071] When the monitored remaining power C of the water quality detection module is less than or equal to C0, the detected water quality information is corrected according to the sample water quality information parameter matrix and the remaining power, and the water quality detection module is controlled to output the corrected water quality information.

[0072] This embodiment pre-sets the sample water quality information parameter matrix corresponding to the remaining power and water quality information value. When the remaining power C≤C0, the corresponding water quality information can be directly obtained from the sample water quality information parameter matrix according to the current remaining power and water quality information, and the water quality information is output. The accuracy of the water quality information is guaranteed, and the influence of low power on the accuracy of the water quality information is avoided. This method of correcting water quality information is simple, convenient and efficient.

[0073] As another implementation of this embodiment, the water quality monitoring module includes a cloud server for correcting data.

[0074] When the remaining power of the monitored water quality detection module is C≤C0, the cloud server is controlled to output the corrected water quality information according to the detected water quality information and the current remaining power. Specifically, the cloud server fits a continuous function based on the historical remaining power and water quality information; the current remaining power is brought into the continuous function, and finally the corrected water quality information is obtained.

[0075] The water quality information obtained in this embodiment is more accurate and has a small error with the actual water quality information. The washing / rinsing program of the washing machine is controlled by the corrected water quality information, so that the washing efficiency of the washing machine is higher, water resources are wasted less, and the cleanliness of the clothes is higher.

[0076] As another embodiment of the present invention, Figure 3 and Figure 4 As shown, the working state of the water quality detection module includes a normal state and an abnormal state. t = 0, it can be determined that the water quality detection module is not immersed in the washing water and cannot detect the water quality information. The output water quality information S t The water quality detection module is determined to be in an abnormal state, and the water quality detection module is controlled to output the average value of the historical water quality information, or output the last water quality information S t-1 .

[0077] When the detected water quality information S t When >0, it is determined that the water quality detection module is in a normal state, and the water quality detection module is controlled to directly output the detected water quality information.

[0078] The above steps are repeated. When the working time t≥t0, it indicates that the washing / rinsing of the washing machine is completed, and the water quality detection module is controlled to stop working.

[0079] In this embodiment, when the detected water quality information S t = 0, output the average value of historical water quality information, or output the last water quality information S t-1 , instead of outputting 0, the output water quality information is accurate, avoiding the interference of water quality information due to abnormal operation of the water quality detection module.

[0080] Specifically, as an implementation of this embodiment, the water quality monitoring module includes a cloud server. The cloud server monitors the current water quality information S according to the historically detected water quality information. t Perform data fitting and control the water quality detection module to output the fitted water quality information.

[0081] The cloud server uses historical water quality information to analyze the current water quality information S t The water quality information obtained by data fitting is more accurate and has a small error. The washing / rinsing program of the washing machine is controlled by the corrected water quality information, which effectively saves the water consumption of the washing machine while ensuring that the clothes can be washed quickly.

[0082] As another embodiment of the present invention, Figure 5 and Figure 6 As shown, the water quality information difference ΔS0 and the working time t0 are preset. The working time t0 can be a fixed value; or the working time t0 will change with the running time of the washing machine; if the working time of the washing machine is extended, t0 will increase to ensure that the water quality detection module is in a working state when the washing machine is washing / rinsing. The working time t0 is greater than or equal to the washing and rinsing time of the washing machine.

[0083] Get the currently detected water quality information St The last water quality information S t-1 The difference between them is ΔS;

[0084] When the acquired difference ΔS≥ΔS0, the water quality detection module is controlled to correct the detected water quality information and output the corrected water quality information;

[0085] When the obtained difference ΔS<ΔS0, the water quality detection module is controlled to output the water quality information value S t .

[0086] The above steps are repeated. When the working time t≥t0, it indicates that the washing / rinsing of the washing machine is completed, and the water quality detection module is controlled to stop working.

[0087] In this embodiment, when the difference ΔS≥ΔS0 is obtained, that is, the currently detected water quality information S t The last water quality information S t-1 The difference between them is large, indicating that the water quality detection element may be covered by the foam in the washing water and cannot accurately detect the water quality information of the washing water.

[0088] Alternatively, the water quality detection element may be covered by solid matter insoluble in the washing water, and the water quality information of the washing water cannot be accurately detected. This ultimately results in inaccurate water quality information values ​​being detected. In this case, by correcting the detected water quality information and outputting the corrected water quality information, the interference of the above situation on the water quality information can be effectively avoided, and the output water quality information is more accurate.

[0089] As an implementation of this embodiment, the water quality monitoring module includes a cloud server; when the acquired difference ΔS≥ΔS0, the cloud server compares the current water quality information value S with the historically detected water quality information value. t Perform data fitting and output the fitted water quality information.

[0090] Alternatively, the cloud server calculates and outputs the corrected water quality information based on the acquired difference ΔS.

[0091] The cloud server fits the current water quality information value, and the water quality information obtained is more accurate with less error. The washing / rinsing program of the washing machine is controlled according to the corrected water quality information, and the control of the washing machine is more accurate, which effectively saves the water consumption of the washing machine while ensuring that the clothes can be cleaned.

[0092] As another implementation of this embodiment, when ΔS≥ΔS0, the current water quality information value S is removed. t , output the last water quality information value S t-1 ;

[0093] Alternatively, the water quality detection module establishes a corresponding sample water quality information parameter matrix according to different ΔS, and when the obtained difference ΔS≥ΔS0, corrects the detected water quality information according to the sample water quality information parameter matrix corresponding to the obtained difference ΔS, and outputs the corrected water quality information.

[0094] In this embodiment, when ΔS≥ΔS0, the current water quality information value S is removed. t , output the last water quality information value S t-1 , so that the output water quality information value is less different from the actual water quality information value, ensuring the relative accuracy of the water quality information. Controlling the washing / rinsing program of the washing machine according to the output water quality information can save the water consumption of the washing machine and ensure the cleanliness of the clothes.

[0095] The current water quality information is corrected through the sample water quality information parameter matrix corresponding to the difference ΔS, ensuring the accuracy of the water quality information value and avoiding the influence of the low-power water quality detection module on the accuracy of the water quality information.

[0096] The present invention also provides a washing machine, which adopts the water quality information processing method described in any of the above schemes. The washing / rinsing program of the washing machine is controlled by the output water quality information, which saves water and power consumption of the washing machine on the basis of ensuring that the clothes can be cleaned, improves the working efficiency of the washing machine, and makes the washing machine more efficient, energy-saving and environmentally friendly.

[0097] The above is only a preferred embodiment of the present invention, and does not limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment, it is not used to limit the present invention. Any technician familiar with this patent can make some changes or modify the technical contents suggested above into equivalent embodiments without departing from the scope of the technical solution of the present invention. However, any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present invention without departing from the content of the technical solution of the present invention still fall within the scope of the solution of the present invention.
