Description

Technical Field

[0001] This invention relates to an intelligent cleaning method for a cleaning machine, a storage medium, and a cleaning machine. Background Technology

[0002] The use of various cleaning machines such as dishwashers and fruit and vegetable cleaning devices is becoming more and more common, and people are also putting forward higher and higher requirements for the performance of cleaning machines, such as increasingly strict constraints on water consumption.

[0003] Existing washing machines typically involve multiple cleaning cycles. After each cycle, the wastewater is drained before starting the next cycle. To ensure effective cleaning in each cycle, a sufficient water supply is required, which fails to meet the need for lower water consumption. To reduce the total water consumption and achieve water conservation, Chinese invention patent application No. 202111200931.2 (Publication No. CN113940601A), entitled "Dishwasher and its Control Method, Device, and Storage Medium," proposes a water-saving solution. The disclosed dishwasher includes an inner tank, a first circulating water path, a second circulating water path, and a water purification device. The first circulating water path connects to the cleaning chamber at both ends. The second circulating water path has an inlet and an outlet connected to the cleaning chamber. The water purification device is located in the second circulating water path and is used to purify the water transported in the second circulating water path. The water purification device includes at least one of activated carbon, water-purifying cotton, and a permeable membrane; that is, the water purification device is a filtration device that uses filtration to purify the water. The control method of this dishwasher includes: in the first cleaning stage, closing the second circulating water path and opening the first circulating water path, so that the cleaning water flows through the cleaning chamber multiple times; closing the first circulating water path and opening the second circulating water path, so that the cleaning water is purified by a water purification device and then transported to the cleaning chamber; in the second cleaning stage, the purified water is used as the cleaning water for the second cleaning stage. Additionally, a water storage device is provided on the second circulating water path, located downstream of the water purification device. Thus, the purified water generated during the cleaning process can be temporarily stored in the water storage device and reused after a period of time. The dishwasher in this invention application filters water through an external water purification device and then recycles the filtered purified water for cleaning. While this solution can achieve water conservation and reduce water consumption, the setup of the water purification device, the first circulating water path, and the second circulating water path increases the overall size of the dishwasher, requiring more installation space and increasing the difficulty of installation in small spaces; it also increases the cost of the device. Furthermore, since the water filtered by the water purifier needs to be stored in a storage tank for later use, and the purification level of the water purifier is relatively low, especially if the dishwasher is not used for a long time, the purified water can inevitably develop bacteria and odors during long-term storage. Even if the purified water is used promptly, if the water purifier and storage tank are not cleaned regularly, the dirt particles in the purified water will accumulate over time, forming a layer of dirt on the inner walls of the water purifier and storage tank, which will also lead to the growth of bacteria and odors. Summary of the Invention

[0004] The first technical problem to be solved by the present invention is to provide an intelligent cleaning method for a cleaning machine that reduces water consumption, balances cleaning efficiency, and avoids problems such as bacterial growth and odor.

[0005] The second technical problem to be solved by the present invention is to provide a computer-readable storage medium that stores a computer program / instructions that can be executed by a processor to implement the intelligent cleaning method of the aforementioned cleaning machine.

[0006] The third technical problem to be solved by the present invention is to provide a cleaning machine that applies the aforementioned intelligent cleaning method to the prior art, which significantly reduces water consumption without increasing the cost of the device or the overall size of the cleaning machine, thereby achieving the purpose of water conservation.

[0007] The technical solution adopted by the present invention to solve the first technical problem mentioned above is: an intelligent cleaning method for a cleaning machine, wherein the cleaning machine includes n cleaning processes, and during at least one of the cleaning processes, the cleaning water in the cleaning chamber is left to stand, thereby forming a standing water consisting of upper clean water and lower wastewater. The lower wastewater in the standing water is discharged, and then the upper clean water remaining in the cleaning chamber is applied to subsequent cleaning processes and is completely discharged when the cleaning process is completed.

[0008] To ensure cleaning effectiveness, after draining the lower layer of wastewater from the settling water, fresh water is added to the cleaning chamber. The volume of water drained from the lower layer is X. i The amount of new water added is X. i i represents the current cleaning cycle number, i≤n;

[0009] Then, the cleaning process is continued using the upper layer of clean water and fresh water.

[0010] Optionally, the lower-level wastewater discharge volume corresponding to different working modes and cleaning stages can be preset, and the discharge volume X of lower-level wastewater can be determined based on the current working mode and the current cleaning stage. i ;or

[0011] During the cleaning process, data on the state of contaminants in the cleaning water before it settles is collected. Based on this data, the volume X of wastewater to be discharged from the lower layer is determined. i .

[0012] To maximize the utilization of the purified water after settling and minimize water consumption, the process involves cyclical cleaning, settling the cleaning water in the cleaning chamber, draining the lower layer of wastewater from the settling water, and replenishing the cleaning chamber with fresh water during at least one cleaning cycle, until the preset number of cycles C is reached. i After cleaning for a period of time, drain the cleaning water from the cleaning chamber to complete the cleaning process.

[0013] Optionally, the number of cycles corresponding to different working modes and cleaning passes can be preset, and the preset number of cycles C is determined according to the working mode and the number of passes of the current cleaning operation.i ;or

[0014] During the cleaning process, data on the state of contaminants before the cleaning water is allowed to settle is collected, and the preset number of cycles C is determined based on this data. i .

[0015] Preferably, before performing the cleaning step, the cleaning water in the cleaning chamber is heated to a set temperature, and then the cleaning step is performed.

[0016] To ensure the effective separation of contaminants from the cleaning water during each settling period, the settling time of the cleaning water in the cleaning chamber is T. i , where i represents the current cleaning cycle number, i≤n.

[0017] Optionally, different working modes and cleaning passes can be preset with different settling times. The settling time T is determined based on the current working mode and the current number of cleaning passes. i ;or

[0018] During the cleaning process, data on the state of contaminants in the cleaning water before it settles is collected, and the settling time (T) is determined based on this data. i .

[0019] The technical solution adopted by the present invention to solve the second technical problem mentioned above is: a computer-readable storage medium storing a computer program / instruction thereon, which, when executed by a processor, implements the aforementioned intelligent cleaning method of the cleaning machine.

[0020] The technical solution adopted by the present invention to solve the third technical problem mentioned above is as follows: a cleaning machine, including a housing with a cleaning chamber, a cleaning mechanism disposed in the housing, a controller and a memory, wherein the controller is electrically connected to the memory and the cleaning mechanism, and the memory stores a computer program / instruction, which, when executed by the controller, realizes the aforementioned intelligent cleaning method of the cleaning machine.

[0021] Compared with the prior art, the advantages of the present invention are as follows: The intelligent cleaning method of the cleaning machine in the present invention performs static treatment of the cleaning water during the cleaning process. This not only allows the upper layer of clean water in the static water to be used for cleaning again, thereby reducing the total water consumption, but also allows all the upper layer of clean water in the static water to be discharged at the end of the cleaning process, thus completely solving the problem of bacteria growth and odor caused by the presence of tiny dirt in the upper layer of clean water.

[0022] Furthermore, because the upper layer of purified water and the lower layer of wastewater in the standing water at the end of the cleaning process are all discharged in a timely manner, there is no need to worry about bacterial contamination or odor caused by storing the upper layer of purified water. Correspondingly, the purification requirements for the upper layer of purified water that needs to be reused can also be appropriately reduced. Therefore, only a short standing time is required, which will not excessively affect the cleaning efficiency. In this way, while balancing the cleaning efficiency, the problem of bacterial growth and odor caused by standing cleaning water is completely solved.

[0023] The cleaning machine that uses the aforementioned intelligent cleaning method completes the static treatment of the cleaning water within the cleaning chamber during the cleaning process, and can also discharge it all in a timely manner at the end of the cleaning process. Therefore, no additional pipelines or water storage equipment are required. In other words, the cleaning water can be recycled without adding any additional devices. This achieves the effect of reducing water consumption without increasing the cost or overall size of the cleaning machine. Attached Figure Description

[0024] Figure 1 This is a flowchart of the intelligent cleaning method of the cleaning machine in an embodiment of the present invention. Detailed Implementation

[0025] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0026] This embodiment relates to a cleaning machine and an intelligent cleaning method for the cleaning machine. The cleaning machine includes a housing with a cleaning chamber, a cleaning mechanism housed within the housing, and a water inlet and a water outlet on the cleaning chamber. Typically, a water inlet pipe is connected to the water inlet to connect to a water source, thereby allowing water to enter the housing. To control the opening and closing of the water inlet and effectively control the water flow, a water inlet mechanism, such as a water inlet valve or water inlet switch, is usually installed at the water inlet. Similarly, a drain pipe is typically connected to the water outlet to drain water from the cleaning chamber. Likewise, to control the opening and closing of the drain and the drainage volume, a drain mechanism, such as a drain valve or drain switch, is usually installed at the drain outlet to drain water.

[0027] The cleaning machine also includes a controller and a memory. The controller is electrically connected to the memory, the cleaning mechanism, the water inlet mechanism, and the drainage mechanism. The memory stores computer programs / instructions, which, when executed by the controller, implement the intelligent cleaning method of the cleaning machine described below.

[0028] like Figure 1 As shown, the intelligent cleaning method of the cleaning machine in this embodiment is as follows.

[0029] A washing machine consists of n washing cycles. The number of cycles in a single washing task varies depending on the machine model and operating mode. For example, the number of cycles differs depending on whether the task is washing fruits and vegetables or washing tableware. To facilitate understanding, the number of washing cycles can be specifically defined. For instance, the first washing cycle might be defined as 1, and so on, with subsequent cycles numbered 1, 2, 3, ..., n.

[0030] During at least one cleaning step, the cleaning mechanism can be stopped for a period of time to allow the cleaning water in the cleaning chamber to settle. The settled water will then separate into two layers: a lower layer of solid-liquid mixed wastewater with a high content of solid particles such as impurities and dirt, and a lower layer of purified water that has been clarified through settling. This results in a settling water system consisting of an upper layer of purified water and a lower layer of wastewater. After the settling process, the upper layer of purified water, due to its increased cleanliness, can be reused in the cleaning process, thus reducing the amount of fresh water entering the system and lowering overall water consumption. Specifically, the controller can open the drain outlet to discharge only the lower layer of wastewater from the settling water, and then close the drain outlet, allowing the upper layer of purified water to remain in the cleaning chamber for continued use. This purified water is then applied to subsequent cleaning tasks, and finally, all the purified water in the cleaning chamber is discharged at the end of the cleaning process.

[0031] Based on the specific water consumption requirements and cleaning functions of the cleaning machine, determine in which cleaning process the function of allowing the cleaning water to settle is incorporated. For example, for a cleaning machine with three cleaning stages, the function of allowing the cleaning water to settle can be incorporated during each cleaning stage, or it can be incorporated only during the first, second, or third cleaning stages, or only during the first and second cleaning stages.

[0032] For a cleaning task that requires the use of static cleaning water, the intelligent cleaning method of this cleaning machine specifically includes the following steps S1 to S7.

[0033] S1. Introduce a set amount of water Q into the cleaning chamber.

[0034] S2. Control the cleaning mechanism to perform the cleaning steps. The specific working time of the cleaning steps can be preset during the research and development.

[0035] S3. After the cleaning steps are completed, control the cleaning mechanism to stop working, and then let the cleaning water in the cleaning chamber stand still. The standing time of the cleaning water in the cleaning chamber is T. i Let i represent the current cleaning cycle number, i≤n, and the settling time T. iThe goal is to ensure that the washing water achieves the preset stratification effect. For example, the settling time T can be... i It is set to a fixed value, but in order to achieve a better settling and stratification effect of the cleaning water for different cleaning conditions, the settling time T in this embodiment is... i The specific method for determining it can be achieved using one of the following two approaches.

[0036] One method for determining the settling time is as follows: Under different working modes, the items to be cleaned may vary, resulting in significant differences in the level of contaminants in the cleaning water. Furthermore, the level of contaminants in the cleaning water also differs considerably between different cleaning passes. For example, earlier cleaning passes may contain more contaminants, requiring longer settling times, while later passes may contain less contaminants, requiring shorter settling times. Based on this, settling times are preset for different working modes and cleaning passes. These preset values ​​can be obtained through experimental testing during the R&D phase. Then, based on the preset settling time data, the settling time T is determined according to the current cleaning mode and the current number of cleaning passes. i .

[0037] Another method is to detect and acquire data on the state of contaminants in the cleaning water before it settles during the cleaning process, and then determine the settling time as T based on this data. i The data on the state of the contaminants and the settling time are T. i The corresponding calculation relationship can be obtained through experimental testing during the research and development phase. This method can more accurately reflect the actual working conditions of the cleaning water, thereby determining the settling time T. i This allows for greater accuracy, enabling the cleaning water to achieve the desired stratification effect to the greatest extent possible, without wasting time and ensuring cleaning efficiency.

[0038] S4. After the cleaning water has settled, it forms a settling water system consisting of an upper layer of clean water and a lower layer of wastewater. The drainage mechanism is activated to open the drain outlet, discharging the lower layer of wastewater from the cleaning chamber. The volume of wastewater discharged is X. i Let i represent the current cleaning cycle number, i≤n; after draining the lower layer of wastewater from the settling water, replenish the cleaning chamber with fresh water, the amount of which is X. i The amount of new water added is the same as the amount of wastewater discharged from the lower layer, which can effectively ensure the total amount of water used for cleaning in the cleaning chamber, thereby ensuring the cleaning effect.

[0039] At this time, the cleaning water in the cleaning chamber is a mixture of upper-layer purified water and fresh water. The following cleaning work is carried out using the mixed water, thus realizing the recycling of the upper-layer purified water after it has been left to stand.

[0040] The aforementioned water volume X iThe goal is to discharge as much of the lower-layer wastewater, which contains high levels of impurities and contaminants, as possible. Specifically, the water volume can be multiplied by X. i It is set to a fixed value, but in order to retain as much upper-layer purified water as possible for different cleaning conditions and improve the utilization rate of the settled purified water, the water volume X in this embodiment is... i The specific method for determining it can be achieved using one of the following two approaches.

[0041] One method for determining this is as follows: Under different working modes, the items being cleaned may differ, resulting in significant differences in the amount of contaminants in the cleaning water. Furthermore, the amount of contaminants in the cleaning water also varies considerably between different cleaning stages. For example, earlier cleaning stages may have more contaminants in the cleaning water, requiring a larger volume of wastewater, while later stages may have less contaminants, requiring only a smaller volume of wastewater. Based on this, the water volume corresponding to different working modes and cleaning stages is preset. This preset water volume value can be obtained through experimental testing during the R&D phase. Then, based on the preset water volume data, the volume X of wastewater discharged from the lower layer is determined according to the current cleaning mode and the current number of cleaning stages. i .

[0042] Another method is to: during the cleaning process, detect and acquire data on the state of the dirt in the cleaning water before it settles, and determine the volume X of wastewater to be discharged from the lower layer based on this data. i This method can more accurately reflect the actual types and amounts of pollutants in the stagnant water, thereby determining the volume X of wastewater to be discharged from the lower layer. i This allows for more accurate discharge of lower-level sewage with higher contaminant content, preventing either excessive or insufficient discharge.

[0043] S5. Count the number of cycles C from steps S2 to S4, and determine whether C has reached the preset number of cycles C. i If the condition is met, proceed to step S6; otherwise, return to step S2.

[0044] The purpose of step S5 is to increase the utilization of the upper purified water after settling and minimize water consumption. This involves circulating the cleaning process, allowing the cleaning water in the cleaning chamber to settle, draining the lower wastewater from the settling water, and adding fresh water to the cleaning chamber until the preset number of cycles C is reached. i Specifically, this involves repeating steps S2 to S4 until the preset number of iterations C is reached. i .

[0045] Preset number of loops C i This directly affects the reuse rate of the purified water after settling, and thus the total water consumption of the overall cleaning process. The preset number of cycles C can be adjusted as needed. iSetting it to a fixed value, however, affects its adaptability to specific operating conditions. Therefore, in this embodiment, the water volume X... i The specific method for determining it can be achieved using one of the following two approaches.

[0046] One method for determining the number of cycles is to preset the number of cycles corresponding to different working modes and cleaning passes. Different working modes and cleaning passes are designed to handle different cleaning conditions. For example, for conditions with high levels of contamination, a working mode with better cleaning effect or a mode with more cleaning passes is usually used. If water consumption requirements are strict, different preset cycle numbers need to be set to achieve good cleaning results within the required water consumption. Thus, the preset cycle number C is determined based on the current cleaning working mode and the current number of cleaning passes. i .

[0047] Another method is to detect and acquire data on the state of dirt in the cleaning water before it settles during the cleaning process, and determine the preset number of cycles C based on the dirt state data. i This method can more accurately reflect the type and amount of dirt during the cleaning process. Generally, the more difficult the dirt to clean and the larger the amount of dirt, the more necessary it is to make full use of the clean water in the upper layer of the settling water. This ensures the cleaning effect while maintaining effective water consumption, requiring more cycles and thus necessitating a larger preset number of cycles. The preset number of cycles C determined by this method... i It can more accurately meet the needs of working conditions.

[0048] S6. Control the cleaning mechanism to clean for a period of time using a mixture of upper-level clean water and fresh water. The specific duration of this period can be determined based on the research and development data.

[0049] S7. Drain the cleaning water from the cleaning chamber to complete this cleaning process.

[0050] The intelligent cleaning method of the cleaning machine in this invention performs a static treatment of the cleaning water during the cleaning process. This not only allows the upper layer of clean water in the static water to be used for the cleaning process again, thereby reducing the total water consumption, but also ensures that the upper layer of clean water is completely discharged when the cleaning process is completed. This completely solves the problem of bacteria growth and odor caused by the presence of tiny impurities in the upper layer of clean water.

[0051] Furthermore, because the upper layer of purified water and the lower layer of wastewater in the standing water at the end of the cleaning process are all discharged in a timely manner, there is no need to worry about bacterial contamination or odor caused by storing the upper layer of purified water. Correspondingly, the purification requirements for the upper layer of purified water that needs to be reused can also be appropriately reduced. Therefore, only a short standing time is required, which will not excessively affect the cleaning efficiency. In this way, while balancing the cleaning efficiency, the problem of bacterial growth and odor caused by standing cleaning water is completely solved.

[0052] The cleaning machine that uses the aforementioned intelligent cleaning method completes the static treatment of the cleaning water within the cleaning chamber during the cleaning process, and can also discharge it all in a timely manner at the end of the cleaning process. Therefore, no additional pipelines or water storage equipment are required. In other words, the cleaning water can be recycled without adding any additional devices. This achieves the effect of reducing water consumption without increasing the cost or overall size of the cleaning machine.

[0053] This embodiment also relates to a computer-readable storage medium storing a computer program / instruction thereon, which, when executed by a processor, implements the aforementioned intelligent cleaning method of the cleaning machine.
