Description

Technical Field

[0001] This invention relates to the field of household appliance technology, and in particular to a control method, device, storage medium, and dishwasher. Background Technology

[0002] Existing dishwashers can sterilize through high-temperature sterilization or by using a disinfectant preparation device to ionize water to generate plasma-activated water. The plasma-activated water contains high concentrations of H2O2 (hydrogen peroxide), NO2 (nitrite ions), NO3 (nitrate ions), and a certain concentration of ·OH (hydroxyl radicals), which spread rapidly in the washing chamber with the water flow, effectively killing various bacteria, fungi, viruses, and other microorganisms, achieving a good sterilization and disinfection effect.

[0003] In existing technologies, the preparation of disinfectant water using a disinfectant preparation device is generally treated as a separate washing mode. This means that the disinfection function cannot be effectively applied to other modes, making the process of preparing disinfectant water unsuitable for various washing modes of dishwashers and resulting in wasted washing time. Summary of the Invention

[0004] This invention proposes a control method, device, storage medium, and dishwasher to solve the problem that the process of preparing disinfectant water by existing disinfectant preparation devices cannot adapt to various washing modes of dishwashers, resulting in wasted washing time.

[0005] In one aspect, the present invention provides a method for controlling a dishwasher, the method comprising:

[0006] The total time required for each washing operation before the dishwasher performs the sanitizing operation is recorded as the first time.

[0007] Input the first duration into the preset disinfectant preparation calculation model to calculate the electrolysis voltage frequency or electrolysis voltage amplitude required for the dishwasher's disinfectant preparation device to prepare a preset concentration of disinfectant within the duration of the first duration.

[0008] During each washing operation before the dishwasher performs the disinfection operation, the disinfectant preparation device is controlled to prepare disinfectant according to the electrolysis voltage frequency or electrolysis voltage amplitude.

[0009] Furthermore, after controlling the disinfectant preparation device to prepare the disinfectant according to the electrolysis voltage frequency or electrolysis voltage amplitude, the method further includes:

[0010] When the dishwasher starts performing the disinfection operation, the disinfectant preparation device is controlled to stop preparing the disinfectant.

[0011] The disinfectant prepared by the disinfectant preparation device is delivered into the inner cavity of the dishwasher to perform a disinfection operation on the inner cavity of the dishwasher.

[0012] Furthermore, before obtaining the total time required for each washing operation before the dishwasher performs the sanitizing operation, the method further includes:

[0013] The washing mode of the dishwasher is obtained, including the system preset washing mode or the user-defined washing mode.

[0014] Determine whether the washing mode includes a disinfection operation step;

[0015] If the process includes a disinfection step, a predetermined first volume of water is injected into the disinfectant preparation device.

[0016] Furthermore, if the method includes a disinfection procedure, the method further includes:

[0017] Obtain the washing operations that the dishwasher needs to perform in the current washing mode, and the duration required for each washing operation.

[0018] Furthermore, after obtaining the washing mode of the dishwasher, the method further includes:

[0019] If the dishwasher's washing mode is quick wash, then the first time is marked as a preset second time threshold, and the second time threshold is the shortest time required for the disinfectant preparation device to prepare a disinfectant of a preset concentration;

[0020] If the dishwasher's washing mode is energy-saving wash, then the first duration is marked as a preset third duration threshold, which is the longest duration required for the disinfectant preparation device to prepare a disinfectant of a preset concentration.

[0021] Furthermore, the control calculation model is as follows:

[0022] felectrolysis = F(k1, tbefore sterilization) (1)

[0023] or,

[0024] Velectrolysis = f(k2, tbefore sterilization) (2)

[0025] Among them, f 电解 V is the frequency of the electrolysis voltage. 电解 Let k1 and k2 be the amplitude of the electrolysis voltage, k1 and k2 be the control model coefficients, and t be the voltage amplitude. 消毒前 This is the first duration.

[0026] In another aspect, the present invention provides a control device for a dishwasher, the device comprising:

[0027] The first acquisition module is used to acquire the total time required for each washing operation of the dishwasher before performing the disinfection operation, which is denoted as the first time.

[0028] The calculation module is used to input the first duration into a preset disinfectant preparation calculation model and calculate the electrolysis voltage frequency or electrolysis voltage amplitude required for the dishwasher's disinfectant preparation device to prepare a disinfectant of a preset concentration within the duration of the first duration.

[0029] The control module is used to control the disinfectant preparation device to prepare disinfectant according to the electrolysis voltage frequency or electrolysis voltage amplitude during each washing operation before the dishwasher performs the disinfection operation.

[0030] Furthermore, the device also includes:

[0031] The second acquisition module is used to acquire the washing mode of the dishwasher, which includes a system preset washing mode or a user-defined washing mode.

[0032] The judgment module is used to determine whether the washing mode includes the execution step of disinfection operation;

[0033] The control module is also used to inject a preset first volume of water into the disinfectant preparation device if the execution step includes a disinfection operation.

[0034] Furthermore, the present invention also provides a computer-readable storage medium storing a computer program, wherein the computer program is configured to perform the steps of the above-described method at runtime.

[0035] In addition, the present invention also provides a dishwasher, including a memory, a processor, and a computer program stored in the memory and executable on the processor, wherein the processor executes the computer program to implement the steps of the above method.

[0036] This invention provides a control method, device, storage medium, and dishwasher for a dishwasher. When the dishwasher starts operating, the total time required for each washing operation before the disinfection operation is first obtained and denoted as the first time. This first time is then input into a preset disinfectant preparation calculation model to calculate the electrolytic voltage frequency or amplitude required for the dishwasher's disinfectant preparation device to prepare a disinfectant of a preset concentration within the first time duration. During each washing operation before the disinfection operation, the disinfectant preparation device is controlled to prepare the disinfectant according to the electrolytic voltage frequency or amplitude. This invention utilizes the duration of each washing operation before the disinfection operation to select an appropriate electrolytic voltage frequency or amplitude for disinfectant preparation, perfectly integrating the disinfectant preparation process into the dishwasher's control flow. This ensures the activity of ions in the disinfectant during the disinfection operation.

[0037] The above description is merely an overview of the technical solution of the present invention. In order to better understand the technical means of the present invention and to implement it in accordance with the contents of the specification, and in order to make the above and other objects, features and advantages of the present invention more apparent and understandable, specific embodiments of the present invention are described below.

[0042] Exemplary embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

[0043] It will be understood by those skilled in the art that, unless otherwise defined, all terms used herein (including technical and scientific terms) have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. It should also be understood that terms such as those defined in general dictionaries should be understood to have the meaning consistent with their meaning in the context of the prior art, and should not be interpreted in an idealized or overly formal sense unless specifically defined.

[0044] Figure 1 The flowchart illustrating a dishwasher control method according to an embodiment of the present invention is shown schematically. Figure 1 As can be seen, the dishwasher control method of this invention includes the following steps:

[0045] S1. Obtain the total time required for each washing operation before the dishwasher performs the disinfection operation, and record it as the first time.

[0046] In this embodiment of the invention, the disinfectant solution is prepared by making reasonable use of the time before the disinfection operation, and the disinfection operation is integrated into each washing mode, so that the activity of ions in the disinfectant solution is guaranteed when the dishwasher performs the disinfection operation.

[0047] S2. Input the first duration into the preset disinfectant preparation calculation model to calculate the electrolysis voltage frequency or electrolysis voltage amplitude required for the dishwasher's disinfectant preparation device to prepare a disinfectant of a preset concentration within the duration of the first duration.

[0048] In this embodiment of the invention, a large number of experiments were conducted to determine the correspondence between the disinfectant preparation device producing a disinfectant of a preset concentration and the duration of disinfectant preparation and the frequency or amplitude of the electrolysis voltage, and the corresponding curves were plotted to determine the disinfectant preparation calculation model.

[0049] Figure 2 The curve showing the relationship between the preparation time of the dishwasher disinfectant solution and the electrolysis voltage and frequency provided in this embodiment of the invention is derived from... Figure 2 It is known that to prepare a disinfectant solution that meets the required concentration, the required electrolytic voltage frequency decreases as the preparation time increases. In this embodiment of the invention, a disinfectant preparation calculation model is fitted by capturing the portion of the curve between the shortest duration of the quick wash and the longest duration of the energy-saving wash. In the actual operation of the dishwasher, inputting the first duration into the disinfectant preparation calculation model yields the required electrolytic voltage frequency or amplitude. Its control logic is simple and facilitates the implementation of the washing program.

[0050] Furthermore, the control calculation model is as follows:

[0051]

[0052] Among them, f 电解 V is the frequency of the electrolysis voltage. 电解 Let k1 and k2 be the amplitude of the electrolysis voltage, k1 and k2 be the control model coefficients, and t be the voltage amplitude. 消毒前 This is the first duration.

[0053] S3. During each washing operation before the dishwasher performs the disinfection operation, the disinfectant preparation device is controlled to prepare disinfectant according to the electrolysis voltage frequency or electrolysis voltage amplitude.

[0054] In this embodiment of the invention, after controlling the disinfectant preparation device to prepare disinfectant according to the electrolysis voltage frequency or electrolysis voltage amplitude, the method further includes: when the dishwasher starts to perform disinfection operation, controlling the disinfectant preparation device to stop preparing disinfectant; and conveying the disinfectant prepared by the disinfectant preparation device to the inner cavity of the dishwasher to perform disinfection operation on the inner cavity of the dishwasher.

[0055] Furthermore, the dishwasher control method of this embodiment of the invention further includes determining whether a disinfection operation needs to be performed. Specifically, before obtaining the total time required for each washing operation of the dishwasher before performing the disinfection operation, the method further includes: obtaining the washing mode of the dishwasher, the washing mode of the dishwasher including a system-preset washing mode or a user-defined washing mode; determining whether the washing mode includes the execution steps of the disinfection operation; if it includes the execution steps of the disinfection operation, then injecting a preset first volume of water into the disinfectant preparation device.

[0056] The disinfectant preparation device in this embodiment of the invention specifically generates plasma-activated water through water ionization. This plasma-activated water contains high concentrations of H₂O₂ (hydrogen peroxide), NO₂⁻ (nitrite ions), NO₃⁻ (nitrate ions), and a certain concentration of ·OH (hydroxyl radicals), among other active substances. As the water flows, these substances rapidly spread within the washing chamber, effectively killing various bacteria, fungi, viruses, and other microorganisms, achieving excellent sterilization and disinfection. When using plasma-activated water to disinfect the dishwasher cavity, excessively low disinfectant concentrations will result in incomplete sterilization, while excessively high concentrations will lead to unnecessary energy waste. Therefore, it is only necessary to control the disinfectant preparation device to prepare a disinfectant solution of a preset concentration before executing the disinfection operation step. Furthermore, prolonged storage of the disinfectant solution will reduce its activity. Therefore, the optimal real-time method is to accurately calculate the duration before the disinfection operation step, so as to prepare the disinfectant solution of the preset concentration within that duration. This embodiment of the invention minimizes energy waste while ensuring the activity and sterilization effect of the disinfectant solution.

[0057] Furthermore, if the method includes a disinfection operation step, it further includes: obtaining the washing operations that the dishwasher needs to perform in the current washing mode, and the duration required for each washing operation, so as to facilitate the subsequent calculation of the first duration.

[0058] It should be noted that different washing modes in a dishwasher generally include a pre-wash stage, a main wash stage, a rinsing stage, a sanitizing stage, a washing stage, a hot rinsing stage, and a drying stage. The number of repetitions and duration of each stage are generally different depending on the washing mode. Therefore, it is necessary to determine each washing operation and its duration based on the dishwasher's washing mode in order to calculate the duration of the subsequent first wash.

[0059] Furthermore, to further streamline the control process, after obtaining the washing mode of the dishwasher, the method in this embodiment of the invention further includes:

[0060] If the dishwasher's washing mode is quick wash, the first time is marked as a preset second time threshold, which is the shortest time required for the disinfectant preparation device to prepare a disinfectant solution of a preset concentration; if the dishwasher's washing mode is energy-saving wash, the first time is marked as a preset third time threshold, which is the longest time required for the disinfectant preparation device to prepare a disinfectant solution of a preset concentration.

[0061] For the sake of simplicity, the method embodiments are described as a series of actions. However, those skilled in the art should understand that the embodiments of the present invention are not limited to the described order of actions, because according to the embodiments of the present invention, some steps can be performed in other orders or simultaneously. Furthermore, those skilled in the art should also understand that the embodiments described in the specification are preferred embodiments, and the actions involved are not necessarily essential to the embodiments of the present invention.
