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] Energy efficiency and water efficiency are important indicators for evaluating the performance of various cleaning machines such as dishwashers and washing machines. With the revision of the new version of the mandatory national standards for energy efficiency and water efficiency limits and grades for various cleaning machines, comprehensive optimization and improvement requirements have been put forward for cleaning machines in terms of technical requirements and index classification, further raising the energy efficiency and water efficiency access requirements and guiding the industry towards high-quality development.

[0003] For example, existing large-set dishwashers used to be able to perform four water cycles, but based on the implementation of the new standard, they can only use three water cycles. The existing water volume settings cannot meet the requirements of water efficiency cleaning and rinsing rate. Therefore, it is necessary to balance the relationship between cleaning and rinsing rate by setting a new cleaning sequence to meet both the cleaning target and the rinsing rate requirements. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a smart cleaning method for cleaning machines that can achieve cleaning indicators and meet rinsing rates while reducing energy and water efficiency, and meet the new energy and water efficiency limits and grade requirements, in light of the above-mentioned prior art.

[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 / instruction that can be executed by a processor to implement the aforementioned intelligent cleaning method of the 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 for cleaning machines, in contrast to the prior art.

[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 at least three cleaning processes, and when the last cleaning process of the current cleaning work is being carried out, a water volume X is retained during drainage for use in the first cleaning process of the next cleaning work.

[0008] To minimize the amount of residual water after the first cleaning step and reduce detergent residue, the cleaning machine is intermittently vibrated after the first cleaning step is completed. This promotes the accumulation and discharge of water droplets inside the machine, thus achieving the removal of residual water from the first cleaning step.

[0009] Preferably, the intermittent period T and the vibration frequency F are set, and the cleaning machine is controlled to vibrate according to the intermittent period T, with a vibration time t within each intermittent period T, where t≤T.

[0010] Preferably, the vibration frequency F satisfies: 5Hz ≤ F ≤ 10Hz.

[0011] Preferably, the cleaning machine includes a housing with a cleaning chamber, a valve pump disposed on the housing for draining water, a bracket disposed inside the housing for placing the items to be cleaned, and a drive mechanism disposed on the housing and drivenly connected to the bracket.

[0012] The control valve pump vibrates, and the control drive mechanism drives the support to vibrate, thereby achieving vibration control of the cleaning machine.

[0013] To minimize the amount of residual water after the first cleaning step and reduce detergent residue, the cleaning machine is kept stationary for a set time T0 after the first cleaning step is completed. This allows the free water inside the cleaning machine to drip, collect, and drain naturally, thus achieving the removal of residual water from the first cleaning step.

[0014] To ensure that the concentration of residual detergent gradually decreases during the second cleaning process, the second cleaning process of the cleaning machine includes N rinsing operations, where N≥3;

[0015] Perform N rinsing operations in sequence with progressively decreasing water volume.

[0016] In order to ensure thorough cleaning during the main wash and to reserve as much water as possible for the second washing process, the washing machine includes a housing with a cleaning chamber, a spray mechanism and a support set inside the housing, and a drive mechanism set on the housing and drivenly connected to the support; the spray mechanism includes a spray arm with spray holes.

[0017] Reduce the water volume in the first cleaning step by S;

[0018] To match the water volume S, reduce the number of spray holes on the spray arm;

[0019] During each process, while controlling the spraying mechanism to perform the spraying work, the drive bracket is controlled to move back and forth inside the box.

[0020] 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 described intelligent cleaning method for a cleaning machine.

[0021] The technical solution adopted by the present invention to solve the third technical problem mentioned above is as follows: a cleaning machine, including a box with a cleaning chamber inside, a spray mechanism installed inside the box, and a valve pump connected to the drain outlet of the box through a drain pipe, characterized in that: it further includes a controller and a memory, wherein the controller is electrically connected to the memory, the spray mechanism, and the valve pump;

[0022] The memory stores computer programs / instructions, which, when executed by the controller, implement the aforementioned intelligent cleaning method for the cleaning machine.

[0023] As an improvement, the box is also provided with a bracket for placing cleaning items, and a drive mechanism connected to the bracket to drive the bracket to vibrate. The drive mechanism is electrically connected to the controller.

[0024] The cleaning machine uses the aforementioned intelligent cleaning method to perform the cleaning work.

[0025] 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 retains a portion of water after each cleaning operation for use in the main cleaning process of the next cleaning operation. On the one hand, it does not affect the cleaning effect of the main cleaning process, and on the other hand, it can minimize the water consumption of the main cleaning process. Thus, while limiting the total water consumption, it can fully meet the rinsing water consumption of the second cleaning process, ensuring that the rinsing rate can meet the new version of the energy efficiency and water efficiency limits and grade requirements.

[0026] The cleaning machine that uses this intelligent cleaning method can effectively balance the relationship between cleaning and rinsing rates, achieving both cleaning targets and rinsing rate requirements. Attached Figure Description

[0027] Figure 1 This is a flowchart of the intelligent cleaning method of the cleaning machine in an embodiment of the present invention. Detailed Implementation

[0028] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0029] The intelligent cleaning method for cleaning machines in this embodiment can be applied to various cleaning machines, such as dishwashers and fruit and vegetable cleaning machines.

[0030] After the revision of the new national standards for energy efficiency and water efficiency limits and grades, the total water consumption of washing machines during cleaning operations has been reduced. For example, for dishwashers, the larger the place setting capacity, the more detergent is used during the cleaning process, and the more difficult it is to meet the rinsing rate requirements. For instance, for a 20-place setting dishwasher, the water consumption for Grade 1 in the old standard was 14.8325L, while in the new standard it is 10.2L. The new standard requires a reduction of 4.6L in water consumption compared to the old standard, and this reduction in water will significantly affect the rinsing rate.

[0031] The intelligent cleaning method of the cleaning machine in this embodiment ensures that the water intake for each cleaning operation meets the new standard, while maintaining the water usage for each cleaning operation consistent with or even reducing the water intake for the old standard. This achieves both the cleaning efficiency and rinsing rate requirements.

[0032] like Figure 1 As shown in the figure, the intelligent cleaning method of the cleaning machine in this embodiment is as follows.

[0033] The cleaning machine includes at least three cleaning processes. The first process is the main washing process, during which detergent is added to the machine to achieve the required level of cleanliness for the items to be washed. The final cleaning process is usually a rinsing process, where the water is highly clean and the detergent content is very low, meeting the rinsing rate requirements. The process between the main washing and rinsing processes is usually a rinsing process. During rinsing, in addition to removing residual contaminants, the main focus is on removing any remaining detergent residue, ensuring that the rinsing rate requirements are met after this process.

[0034] In this embodiment, the water used in the final rinsing step has a high level of cleanliness, almost reaching the standard of freshly inlet water. Therefore, during the final rinsing step of the current cleaning process, a water volume X is retained during drainage for use in the first rinsing step of the next cleaning cycle. The water volume X retained after the final rinsing step is determined according to specific needs. In this embodiment, the retained water volume is sufficient to ensure that this portion of water is not visible in the item placement area of ​​the washing machine. As in the applicant's previous patent application, the bottom of the washing machine's casing has a recessed water cup structure, with a filter plate covering the upper opening of the water cup. In this embodiment, the retained water volume X is the water capacity of the water cup. Thus, the water remaining in the water cup will not be visible in the placement area of ​​dishes, fruits, and other cleaned items, and the user will not have any additional questions.

[0035] As mentioned earlier, in the old standard, the water consumption for the first cleaning step was 4.2L. In this embodiment, if the water cup capacity is 1.5L, the water retention capacity X can be set to 1.4L. When performing the first cleaning step in the next cleaning operation, only 2.8L of water needs to be added, and the cleaning machine will have 4.2L of water available for the first cleaning step, maintaining the same actual water consumption as the first cleaning step under the old standard.

[0036] Detergent is typically added during the first cleaning step, resulting in a relatively high detergent residue in the discharged water. In this embodiment, the goal is to drain the cleaning water from the first step as completely as possible, minimizing residue within the cleaning machine and thus facilitating subsequent rinsing and reducing its difficulty. This embodiment utilizes Method 1 and / or Method 2 to maximize the discharge of residual water from the first cleaning step, reducing detergent residue on the inner walls, structure, and items being cleaned within the cleaning machine.

[0037] Method 1: After completing the drainage work of the first cleaning process, control the cleaning machine to vibrate intermittently. Through mechanical vibration, promote the water droplets inside the cleaning machine to gather, fall and be discharged, so as to realize the discharge of residual water in the first cleaning process.

[0038] When implementing vibration control, the intermittent period T and vibration frequency F are set. The cleaning machine is controlled to vibrate according to the intermittent period T, with a vibration time t within each intermittent period T, where t ≤ T. The vibration frequency F satisfies: 5Hz ≤ F ≤ 10Hz. The specific vibration frequency is selected based on the structural requirements of the cleaning machine.

[0039] Furthermore, based on the specific structure of the cleaning machine, a specific vibration control target is determined. Vibration generates minute mechanical disturbances, causing water film rupture points to form on the inner wall of the cleaning machine and the surface of the items being cleaned, accelerating the accumulation and falling of water droplets. Experimental data from this applicant shows that appropriate vibration can increase the dripping efficiency of water droplets by 30-40%. The dripping water droplets collect and are discharged through the cleaning machine's drainage channel.

[0040] In this embodiment, the cleaning machine includes a housing with a cleaning chamber and a valve pump installed on the housing for drainage. The valve pump is connected to a drain outlet on the housing via a drain pipe. During operation, drainage is achieved by controlling the opening and closing of the valve in the valve pump and the operation of the pump itself. Additionally, a support for placing items to be cleaned is provided inside the housing. A drive mechanism connected to the support is installed on the housing. By controlling the drive mechanism, the support can vibrate and move. The drive mechanism can employ various existing structures capable of horizontal vibration and movement. Based on the structure of the cleaning machine in this embodiment, when vibration control is required, the valve pump is controlled to vibrate, and the drive mechanism is controlled to drive the support to vibrate, thereby achieving vibration control of the cleaning machine. The vibration of the valve pump causes the entire housing to vibrate at a low frequency, causing water droplets on the inner wall of the housing to fall quickly. The vibration of the support, on the one hand, causes water droplets on the support to fall quickly, and on the other hand, causes water droplets on the items to fall quickly. The falling water droplets are collected and discharged through a valve pump, which reduces the amount of residual water in the cleaning machine after the first cleaning process and reduces the amount of detergent residue in the cleaning machine.

[0041] Method 2: After completing the drainage work of the first cleaning process, set a static residence period for the cleaning machine, that is, control the cleaning machine to remain in a static state for a set time T0. During this process, all components of the cleaning machine, such as pumps, valves, and spray mechanisms, are in a stopped state, allowing more than 90% of the free water in the cleaning machine to drip, collect, and be discharged naturally, thus realizing the discharge of residual water in the first cleaning process.

[0042] When using both Method 1 and Method 2, you can perform Method 1 first, and then Method 2.

[0043] In this embodiment, the cleaning machine includes the aforementioned housing, support, drive mechanism, valve pump, and other components. The housing also houses a spray mechanism to spray water into the cleaning chamber, thereby achieving the cleaning process for each step. The spray mechanism includes a spray arm with spray holes. To further reduce the water intake in the first cleaning step, ensure thorough cleaning during the main wash, and reserve more water for the second cleaning step, the number of spray holes on the spray arm in this embodiment is less than that in existing cleaning machines. By reducing the number of spray holes, the water flow rate during the washing process can be reduced. In this embodiment, particularly during the first cleaning step, the water volume is reduced by S; as shown in the previous example, the reduced water volume S can be less than 4.2L. The number of spray holes on the spray arm is reduced to match the reduced water volume S. However, reducing the number of spray holes means reducing the cleaning trajectory of the spray holes. In this embodiment, when performing each process, while controlling the spraying mechanism to perform the spraying work, the drive bracket is controlled to move back and forth in the box. The back and forth movement of the bracket increases the overall cleaning coverage, thereby making up for the problem caused by saving the number of spray holes, and achieving the purpose of saving the water intake of the first cleaning process for subsequent rinsing water.

[0044] In this embodiment, the second cleaning process of the washing machine is designed as a multi-stage pulse rinsing process. That is, the second cleaning process includes N rinsing operations, where N ≥ 3, and the water flow rate decreases progressively with each rinse, for example, from 2.5 L / min to 1.2 L / min. This ensures that the amount of residual water in the washing machine gradually decreases, and that the concentration of residual detergent gradually decreases during the second cleaning process.

[0045] The intelligent cleaning method of the cleaning machine in this invention retains a portion of water after each cleaning operation for use in the main cleaning process of the next cleaning operation. On the one hand, it does not affect the cleaning effect of the main cleaning process, and on the other hand, it can minimize the water consumption of the main cleaning process. Thus, while limiting the total water consumption, it can fully meet the rinsing water consumption of the second cleaning process, ensuring that the rinsing rate can meet the new energy efficiency and water efficiency limits and grade requirements.

[0046] The present invention also relates to a computer-readable storage medium having a computer program / instructions stored thereon, which, when executed by a processor, implements the described intelligent cleaning method for a cleaning machine.

[0047] This invention also relates to a cleaning machine, comprising a housing with an internal cleaning chamber, a spray mechanism disposed within the housing, a valve pump connected to the drain outlet of the housing via a drain pipe, a support for placing items to be cleaned within the housing, and a drive mechanism driven by the support to drive the support to vibrate. The drive mechanism can employ various existing drive structures capable of both vibration drive and horizontal movement drive.

[0048] It also includes a controller and a memory. The controller is electrically connected to the memory, spray mechanism, valve pump, and drive mechanism. The memory stores computer programs / instructions, which are executed by the controller to realize the aforementioned intelligent cleaning method of the cleaning machine.

[0049] The cleaning machine that uses this intelligent cleaning method can effectively balance the relationship between cleaning and rinsing rates, achieving both cleaning targets and rinsing rate requirements.
