Description

Technical Field

[0001] The present invention relates to the field of household appliance control technology, and in particular to a method and device for cleaning a washing machine. Background Art

[0002] Washing machines are widely used and widely used in daily life. During use, due to factors such as environmental temperature and humidity, long-term storage, clothes that have not been dried for a long time, or raw water quality in different regions / seasons, the humidity inside the washing machine is too high, which will become a breeding ground for microorganisms. Over time, bacteria and mold will accumulate inside, forming stubborn stains and odors. The quality of laundry water in different regions / seasons will also affect the laundry effect. For example, calcium and magnesium ions in hard water combine with surfactants in detergents to form metal salts, causing the detergent to lose its vitality and reduce its main function. It will also make fabric fibers brittle and hard, resulting in unclean laundry and soft clothes after washing.

[0003] Secondly, due to the structural connection design of the inner drum of the drum washing machine, the rubber hose used to connect the drainage pump and the inner drum will always have some water left after the drainage is completed and cannot be completely drained. As a result, the residual water in the inner drum will have the risk of microbial growth due to changes in water quality in different regions or seasons and too long a residual time, causing contamination of the laundry and the inner drum. In addition, some washing machines on the market with barrel self-cleaning function generally rely on strong washing, high-temperature washing or adding detergent to achieve cleaning. It will remind the user to turn on the barrel self-cleaning after a certain number of washes or washing cycles. However, in different water quality areas and different seasons, our laundry water quality will also change. Different water quality will have a significant impact on the growth of microorganisms. If the barrel self-cleaning is judged only based on the number of washes or cycles, it is difficult to accurately judge the sanitation in the barrel and perform timely and effective cleaning.

[0035] The method embodiments provided in the embodiments of the present invention can be executed in a mobile terminal, a computer terminal or a similar computing device. Taking running on a mobile terminal as an example, Figure 1 FIG. 1 is a hardware structure block diagram of a mobile terminal for a washing machine cleaning method according to an embodiment of the present invention. Figure 1 As shown, the mobile terminal may include one or more ( Figure 1 Only one is shown in the figure) a processor 102 (the processor 102 may include but is not limited to a processing device such as a microprocessor MCU or a programmable logic device FPGA) and a memory 104 for storing data, wherein the mobile terminal may also include a transmission device 106 and an input / output device 108 for communication functions.

[0037] According to an embodiment of the present invention, a method embodiment of a washing machine cleaning method is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0038] Figure 2 is a flow chart of a cleaning method for a washing machine according to an embodiment of the present invention. Figure 2 As shown, the method comprises the following steps:

[0039] Step S202, when the standby time of the washing machine exceeds the first predetermined time, obtaining the humidity value inside the washing machine and the tub weight value of the washing machine.

[0040] Figure 3 : is a flow chart of intelligent control of a drum washing machine according to an embodiment of the present invention. Figure 3As shown, after judging whether the standby time of the washing machine is greater than two hours, determine the next operation.

[0041] In this embodiment, when the standby time of the washing machine exceeds two hours (i.e., the first predetermined time), the humidity value inside the washing machine and the barrel weight value of the washing machine can be obtained to understand the working status and washing effect of the washing machine. By monitoring the humidity value inside the machine, it can help determine whether there is sufficient moisture inside the washing machine to ensure the smooth progress of the washing process. The barrel weight value can reflect the weight of the washing items inside the washing machine, help understand the quantity and quality of the washing items, and then adjust the working mode and washing program of the washing machine to obtain better washing effects.

[0042] Step S204, comparing the humidity value in the machine with the humidity threshold to obtain a humidity comparison result, and comparing the barrel weight value with the net barrel weight of the washing machine to obtain a barrel weight comparison result.

[0043] In this embodiment, comparing the humidity value in the machine with the humidity threshold can help determine whether the current environment is suitable for running the washing machine, so as to avoid using the washing machine in an overly humid or overly dry environment resulting in poor washing results or damage to the machine. Comparing the barrel weight value with the net barrel weight of the washing machine can help determine whether there are enough clothes put into the washing machine, so as to ensure the washing effect and save water and electricity resources.

[0044] Step S206, when the humidity comparison result indicates that the humidity value in the machine is greater than or equal to the humidity threshold and the barrel weight comparison result indicates that the barrel weight value is less than or equal to the net barrel weight, determine the first cleaning strategy of the washing machine according to the turbidity difference and oxygen consumption difference between the raw water and the residual water of the washing machine.

[0045] In this embodiment, when the humidity value in the machine is less than or equal to the humidity threshold and the barrel weight value is less than or equal to the net barrel weight, the first cleaning strategy of the washing machine can be determined according to the turbidity difference and oxygen consumption difference between the raw water and the residual water of the washing machine. By monitoring the changes in the water quality in the washing machine, the cleanliness of the water in the washing machine can be judged in time, so as to take corresponding cleaning measures to ensure the washing effect and service life of the washing machine, reduce the risk of bacteria and odor growth inside the washing machine, and protect the health of users.

[0046] It should be noted that the above-mentioned water quality refers to the water hardness used to measure the content of calcium and magnesium ions in the water. The higher the water hardness, the more calcium and magnesium ions in the hard water combine with the surfactants in the detergent to generate more metal salts, which makes the washing effect poor and the clothes hard after washing; the above-mentioned turbidity is an indicator used to measure the content of suspended particles and colloids in the water. The higher the turbidity of the water, it usually means that there are more suspended particles and microorganisms, which may include bacteria, viruses and protozoa; the above-mentioned oxygen consumption (ie, COD) is used to assess the degree of organic pollutants in the water. Organic matter is an important source of nutrition for the growth and reproduction of microorganisms. They can be decomposed by microorganisms and converted into energy required by microorganisms. The higher the COD value, the more organic matter there is in the water, which can provide microorganisms with rich nutrients and is more conducive to their growth.

[0047] Step S208, when the humidity comparison result indicates that the humidity value in the washing machine is greater than the humidity threshold and the tub weight comparison result indicates that the tub weight value is greater than the net tub weight, determine the second cleaning strategy of the washing machine.

[0048] In this embodiment, when the humidity value in the machine is greater than the humidity threshold and the barrel weight value is greater than the net barrel weight, the second cleaning strategy of the washing machine can be determined, and dehumidification processing can be automatically performed when there are clothes in the machine and the humidity is high to prevent the humidity in the machine from being too high, causing bacteria to grow and odor to be generated, keeping the washing machine dry and clean, extending the service life of the washing machine and ensuring the washing effect.

[0049] Step S210, controlling the washing machine to perform a cleaning operation according to the first cleaning strategy or the second cleaning strategy.

[0050] In this embodiment, the washing machine can be controlled to perform cleaning operations according to corresponding cleaning strategies according to different situations inside the machine, ensuring that the washing machine can effectively clean clothes and maintain good working condition, can better remove dirt and bacteria, keep clothes clean and hygienic, and avoid the growth of odor and mold.

[0051] As can be seen from the above, in an embodiment of the present invention, when the standby time of the washing machine exceeds the first predetermined time, the humidity value inside the washing machine and the barrel weight value of the washing machine are obtained; the humidity value inside the machine is compared with the humidity threshold to obtain a humidity comparison result, and the barrel weight value is compared with the net barrel weight of the washing machine to obtain a barrel weight comparison result; when the humidity comparison result indicates that the humidity value inside the machine is greater than or equal to the humidity threshold and the barrel weight comparison result indicates that the barrel weight value is less than or equal to the net barrel weight, the first cleaning strategy of the washing machine is determined according to the turbidity difference and oxygen consumption difference between the raw water and the residual water of the washing machine; when the humidity comparison result indicates that the humidity value inside the machine is greater than the humidity threshold and the barrel weight comparison result indicates that the barrel weight value is greater than the net barrel weight, the second cleaning strategy of the washing machine is determined; the washing machine is controlled to perform a cleaning operation according to the first cleaning strategy or the second cleaning strategy, thereby achieving the purpose of automatically turning on ventilation or drying or barrel self-cleaning functions according to the water quality and the severity of bacterial growth by real-time monitoring of the humidity, barrel weight, raw water and water quality inside the washing machine, thereby achieving the technical effect of providing a healthy laundry environment for a long time and improving the user's laundry experience, and improving the intelligence and reliability of the washing machine.

[0052] The technical solution provided by the embodiment of the present invention solves the technical problem that the method used in the related art to determine whether the washing machine needs to be cleaned is mainly based on the number of washes or cycles, it is difficult to accurately judge the sanitary conditions in the washing tub, and the washing machine cannot be cleaned in time.

[0053] According to the above embodiment of the present invention, when the standby time of the washing machine exceeds the first predetermined time, before obtaining the humidity value inside the washing machine and the barrel weight value of the washing machine, the cleaning method of the washing machine also includes: after determining that the washing machine is turned on based on the start instruction, obtaining the raw water hardness of the raw water; when it is determined that the raw water hardness is greater than the raw water hardness threshold, adding softener into the washing machine until the washing machine ends the washing program; when it is determined that the raw water hardness is not greater than the raw water hardness threshold, if it is determined that the washing program ends, then starting to count the standby time of the washing machine.

[0054] like Figure 3 As shown, when the washing machine is performing a normal washing program, the water quality detection module will start collecting raw water quality data. When the raw water hardness data collected is calculated to be greater than the limit a (i.e., the raw water hardness threshold), softener will be intelligently added until the washing machine finishes the washing program. The softener can be accurately added according to the raw water hardness value and the water volume ratio, which can alleviate the problems of softener waste and unclean washing. Among them, the setting of the limit a can refer to the hardness limit of drinking water. When it is not greater than the limit a, if it is determined that the washing program has ended, the standby time of the washing machine will be counted to understand the usage of the washing machine.

[0055] According to the above-mentioned embodiment of the present invention, obtaining the humidity value inside the washing machine and the barrel weight value of the washing machine includes: triggering the humidity sensor inside the washing machine to start to collect the humidity value inside the washing machine and obtain the humidity value inside the machine; triggering the weight sensor inside the washing machine to start to collect the barrel weight of the washing machine and obtain the barrel weight value.

[0056] In this embodiment, when the washing program ends and the standby time is greater than two hours, the humidity sensor and weight sensor in the washing machine can be triggered to start. The humidity inside the machine and the weight of the barrel can be monitored in real time through the humidity sensor and the weight sensor to obtain the humidity value inside the machine and the weight value of the barrel.

[0057] According to the above embodiment of the present invention, the first cleaning strategy of the washing machine is determined according to the turbidity difference and oxygen consumption difference between the raw water and the residual water of the washing machine, including: using a water quality detection module to detect the raw water to obtain raw water quality data of the raw water, wherein the water quality detection module detects the raw water when the raw water passes through, the water inlet solenoid valve 1 is opened and the water inlet solenoid valve 2 is closed when the raw water passes through the water quality detection module, the water inlet solenoid valve 1 is located in front of the water inlet of the inner drum of the washing machine, and the water inlet solenoid valve 2 is located at the water storage port of the residual water at the water outlet end of the inner drum; using the water quality detection module to detect the residual water to obtain residual water quality data of the residual water, wherein the water quality detection module detects the residual water when the residual water passes through, the water inlet solenoid valve 1 is closed and the water inlet solenoid valve 2 is opened when the residual water passes through the water quality detection module; determining the turbidity difference and the oxygen consumption difference according to the raw water quality data and the residual water quality data; determining the first cleaning strategy according to the turbidity difference and the oxygen consumption difference.

[0058] In this embodiment, when the humidity in the machine is greater than or equal to 80%RH (i.e., the humidity threshold) and the barrel weight is less than or equal to the net barrel weight (which can be regarded as a state where there is no load in the machine and the humidity is high), the water quality detection module will respectively start the raw water and inner drum residual water data collection modes, calculate the turbidity value / COD value of the residual water in the two barrels minus the turbidity value / COD value of the raw water, that is, the turbidity difference and the COD difference, and determine the first cleaning strategy of the washing machine.

[0059] Figure 4 is a flow chart of the water quality module detection of the washing machine according to an embodiment of the present invention. Figure 4As shown, it is determined whether to intelligently add softener or automatically start the conventional or deep barrel self-cleaning mode according to the water hardness, turbidity and COD, which may include 1-water inlet solenoid valve, 2-inner drum water storage port, 3-water inlet solenoid valve, 4-water quality detection module, 5-pressure regulating pump, 6-wastewater solenoid valve, the water inlet solenoid valve 1 is located in front of the water inlet of the inner drum of the washing machine, at the entrance end of the second branch, and is used to control whether the raw water passes through the water quality detection module 4, the water inlet solenoid valve 3 is located behind the inner drum water storage port of the washing machine, before the second branch water outlet, and is used to control whether the residual water in the inner drum passes through the water quality detection module 4, the water quality detection module 4 is installed behind the second branch water outlet, and is used to detect the water quality of the raw water and the residual water in the inner drum of the washing machine and feedback to the cloud, and the wastewater solenoid valve 6 is used to control the opening and discharge of the sewage after the detection. An ultraviolet lamp will be installed at the inner drum water storage port 2 to sterilize the residual water in the inner drum.

[0060] Optionally, the water quality detection module 4 may include but is not limited to: a hardness detection probe, a TDS detection probe, a turbidity detection probe, a pH probe, a TOC tester, a COD tester, a temperature probe and other detection devices.

[0061] Specifically, the raw water data collection mode is set to automatically run after the humidity in the barrel is greater than or equal to 80% and the barrel weight is less than or equal to the net barrel weight after the washing machine has been washing normally and on standby for two hours. When the raw water data collection mode is turned on, the water inlet solenoid valve 1 (i.e., the water inlet solenoid valve one) and the waste water solenoid valve 6 are opened, and the water inlet solenoid valve 3 (i.e., the water inlet solenoid valve two) is closed. The raw water passes through the second branch, the water quality detection module 4, and is discharged by the waste water solenoid valve 6. At this time, the data read by the water quality detection module 4 is the raw water quality data P1; the inner barrel residual water data collection mode is set to automatically run after the humidity in the barrel is greater than or equal to 80% and the barrel weight is less than or equal to the net barrel weight after the washing machine has been on standby for two hours. When the inner barrel residual water data collection mode is turned on, the water inlet solenoid valve 2 and the waste water solenoid valve 6 are opened, the water inlet solenoid valve 1 is closed, the residual water passes through the water quality detection module 4, and is discharged by the waste water solenoid valve 6. At this time, the data read by the water quality detection module 4 is the inner barrel residual water quality data P2.

[0062] In the above embodiment of the present invention, the first cleaning strategy is determined according to the turbidity difference and the oxygen consumption difference, including: when it is determined that the turbidity difference is less than or equal to the first turbidity threshold and the oxygen consumption difference is less than or equal to the first oxygen consumption threshold, the first cleaning strategy is determined to be: turning on the ventilation function of the washing machine; when it is determined that the turbidity difference is greater than the first turbidity threshold and less than the second turbidity threshold, and the oxygen consumption difference is greater than the first oxygen consumption threshold and less than the second oxygen consumption threshold, the first cleaning strategy is determined to be: turning on the first-level cleaning function of the washing machine; when it is determined that the turbidity difference is greater than the second turbidity threshold and the oxygen consumption difference is greater than the second oxygen consumption threshold, the first cleaning strategy is determined to be: turning on the second-level cleaning function of the washing machine, wherein the cleaning intensity of the first-level cleaning function is less than the cleaning intensity of the second-level cleaning function.

[0063] like Figure 3 As shown, when the turbidity difference ≤ limit b (i.e., the first turbidity threshold) and the COD difference ≤ limit d (i.e., the first oxygen consumption threshold), it means that the humidity in the barrel is just too high and bacteria are easily bred, and the washing machine automatically turns on the ventilation function; when the limit b < turbidity difference < limit c (i.e., the second turbidity threshold) and the limit d < COD difference < limit e (i.e., the second oxygen consumption threshold), it can reflect that the water quality in the inner barrel is poor and polluted, and the washing machine automatically turns on the conventional barrel cleaning mode (i.e., the first level cleaning function of the washing machine); when the turbidity difference > limit c and the COD difference > limit e, it can reflect that the water quality in the inner barrel is very poor and seriously polluted, and the washing machine automatically turns on the barrel deep cleaning mode (i.e., the second level cleaning function of the washing machine).

[0064] It should be noted that the above-mentioned conventional barrel cleaning mode includes main washing combined with post-wash drying, which mainly relies on strong cleaning to flush out pollutants in the barrel through the coordinated adjustment of water volume and rotation speed; the above-mentioned barrel deep cleaning mode includes detergent + silver ions + high-temperature main washing combined with post-wash drying to deeply disinfect and clean the barrel; the settings of the above-mentioned limit values ​​b, c, d, and e are all based on the difference between the turbidity and COD limit values ​​of drinking water and the actual measured values ​​of turbidity and COD of laundry raw water.

[0065] In this embodiment, the corresponding cleaning strategy of the washing machine can be determined according to the range of turbidity difference and oxygen consumption difference, and the cleaning mode of the washing machine can be automatically adjusted according to the turbidity and COD value of the water quality to ensure the cleanliness and hygiene of the inner barrel of the washing machine.

[0066] According to the above embodiment of the present invention, when the humidity comparison result indicates that the humidity value in the machine is greater than the humidity threshold and the barrel weight comparison result indicates that the barrel weight value is greater than the net barrel weight, the second cleaning strategy of the washing machine is determined, including: when the humidity comparison result indicates that the humidity value in the machine is greater than the humidity threshold and the barrel weight comparison result indicates that the barrel weight value is greater than the net barrel weight, turning on the ventilation function of the washing machine; in the process of turning on the ventilation function of the washing machine, obtaining the real-time barrel weight value and the ventilation on time of the washing machine; when the real-time barrel weight value is greater than the net barrel weight and the ventilation on time is greater than the second predetermined time, determining the second cleaning strategy as: turning on the drying function of the washing machine, wherein the first predetermined time is less than the second predetermined time.

[0067] In this embodiment, when the humidity in the machine is greater than 80%RH and the drum weight is greater than the net drum weight (which can be regarded as a state where there is a load and the humidity is high in the machine), the washing machine automatically turns on the ventilation function. The purpose is to prevent the clothes in the machine that have been washed for a long time and not dried from producing odor, and to reduce the temperature and humidity of the environment in the machine. At the same time, the real-time drum weight value and ventilation opening time of the washing machine are obtained through the weight sensor and timer. When the weight sensor and timer sense that the drum weight in the machine is still greater than the net drum weight and the time exceeds 4 hours (that is, the second predetermined time), it means that the clothes have not been taken out. At this time, the washing machine will automatically turn on the drying function to prevent microorganisms from breeding and contaminating the drum and clothes.

[0068] It should be noted that studies have shown that a relative humidity between 40-60% can minimize the total number of bacteria, germs, molds and parasites in the environment. It is also mentioned that the optimal relative humidity for the growth of dust mites is 70%-80%. When the indoor relative humidity is below 51%, dust mites will die from dehydration. Therefore, taking all factors into consideration, the optimal limit for determining the humidity in the above-mentioned machine is between 70%-80%, and users can also set the humidity limit according to their own habits and seasonal or regional changes.

[0069] In addition, bacteria will first experience a lag period during the growth process. During this period, the bacteria will increase in size and have active metabolism, but will divide slowly. The length of the lag period will vary depending on factors such as the type of bacteria, the amount of bacteria, and the nutrients, and is usually 1-4 hours. Therefore, for clothes that have not been washed and dried for a long time, it is best to set the above optimal limit to within four hours for timely processing, which can effectively prevent bacteria from entering the logarithmic phase and the risk of rapid growth. Of course, users can also set the time judgment limit according to their own usage habits. It is recommended to set it within four hours as the best.

[0070] In the above embodiment of the present invention, the cleaning method of the washing machine also includes: when the first cleaning strategy is to turn on the first-level cleaning function or the second-level cleaning function of the washing machine, in the process of controlling the washing machine to perform the cleaning operation according to the first cleaning strategy, obtaining the residual water turbidity of the residual water and the raw water turbidity of the raw water, and obtaining the residual water oxygen consumption of the residual water and the raw water oxygen consumption of the raw water; when it is determined that the residual water turbidity is less than or equal to the raw water turbidity and the residual water oxygen consumption is less than or equal to the raw water oxygen consumption, controlling the washing machine to stop the cleaning operation; when it is determined that the residual water turbidity is greater than the raw water turbidity and the residual water oxygen consumption is greater than the raw water oxygen consumption, turning on the ultraviolet lamp of the washing machine.

[0071] like Figure 3As shown, after the conventional barrel cleaning mode ends, the water quality detection module will once again start the data collection modes of raw water and inner barrel residual water respectively. The program ends when the turbidity value of the inner barrel residual water is ≤ the raw water turbidity value and the COD value of the inner barrel residual water is ≤ the raw water COD value, indicating that the conventional barrel cleaning is effective, otherwise the ultraviolet sterilization will be turned on to control the growth of microorganisms in the inner barrel residual water; after the deep barrel cleaning mode ends, the water quality detection module will once again start the data collection modes of raw water and inner barrel residual water respectively. The program ends when the turbidity value of the inner barrel residual water is ≤ the raw water turbidity value and the COD value of the inner barrel residual water is ≤ the raw water COD value, indicating that the deep barrel cleaning is effective, otherwise the ultraviolet sterilization will be turned on to control the growth of microorganisms in the inner barrel residual water.

[0072] It should be noted that the above-mentioned time for starting ultraviolet sterilization can be set in combination with the actual turbidity and COD measurement values, because turbidity and COD can reflect the degree of water pollution. The higher the organic matter and content in the water, the richer the nutrients it can provide, and the more conducive it is to the growth of bacteria.

[0073] In this embodiment, while controlling the washing machine to perform a cleaning operation according to a first cleaning strategy, the raw water and inner drum residual water data collection mode can be turned on to obtain the residual water turbidity, raw water turbidity, residual water oxygen consumption and raw water oxygen consumption, and the cleaning effect can be determined according to their range. When conventional barrel cleaning or deep barrel cleaning is effective, the washing machine is controlled to stop the cleaning operation, otherwise ultraviolet sterilization is turned on to keep the washing machine clean and hygienic.

[0074] Through the technical solution provided by the above embodiment of the present invention, a method is first proposed to determine whether to intelligently add softener or automatically start the conventional or deep barrel self-cleaning mode according to the water hardness, turbidity and COD. A water quality detection module, humidity sensor, weight sensor and timer are added to the washing machine to monitor the humidity, barrel weight, raw water and water quality inside the washing machine in real time. When the humidity, barrel weight and water quality inside the washing machine reach a certain limit, softener can be intelligently added and ventilation or drying or barrel self-cleaning function can be automatically started. It can effectively reduce the growth of bacteria and the generation of odor inside the washing machine, maintain the hygiene and health of the laundry environment, and provide users with a more intelligent and convenient use experience.

[0075] In the technical solution provided in the above embodiment of the present invention, the following technical problems are solved: 1) the problem of microbial growth and odor in the machine; 2) the problem of reducing the pollution of the drum and clothes when the user forgets to dry the clothes; 3) the problem of the hardness of the raw water affecting the washing effect; 4) the problem of microbial growth in the residual water in the drum of the drum washing machine, which can automatically start different drum cleaning modes according to the change of water quality; 5) the problem of poor user experience caused by the user manually controlling the ventilation or drying or drum self-cleaning function of the washing machine. At the same time, it has the following beneficial effects: 1) reducing the growth of microorganisms and achieving healthy laundry; 2) effectively avoiding the generation of odor and improving the laundry environment; 3) making the washing machine more intelligent and humane.

[0076] That is, the technical solution provided by the embodiment of the present invention comprehensively considers various factors, adopts a suitable raw water data collection mode and an inner drum residual water data collection mode, and an advanced intelligent control program, by monitoring the humidity inside the washing machine and the drum weight in the standby state, and the water quality detection module collects the water quality data of the raw water and the inner drum residual water, and judges the severity of the bacterial growth according to the difference in water quality between the two, so as to timely and effectively start the ventilation or drying or drum self-cleaning function, to inhibit or eliminate the growth of microorganisms in the inner drum or residual water, and alleviate the generation of odor and the growth of microorganisms in the machine. The antibacterial control logic can provide a healthy laundry environment for a long time, improve the user's laundry experience, avoid the shortcomings of the traditional method that it is difficult to judge the sanitary environment of the washing machine and cannot be cleaned in time and effectively, and can reduce the generation of odor and the growth of microorganisms in the machine, so as to provide a healthy laundry environment effectively in the long term.
