Abstract
Description
Technical Field
[0001] This invention relates to the technical field of dishwashers, and specifically provides a control method for a dishwasher, a dishwasher, and a computer storage medium. Background Technology
[0002] Existing dishwasher control methods are compatible with multiple models, and different models of dishwashers may be exported to different countries or regions.
[0003] However, due to significant differences in ambient temperature between different countries and regions, or even different seasons within the same country, the heating process of a dishwasher can be affected. For example, in cold seasons or countries and regions with consistently low temperatures, the ambient temperature can accelerate the dishwasher's heat dissipation, resulting in a slower temperature rise during the heating process.
[0004] Some dishwashers used in the Americas generally use 120V voltage, so they heat up slowly. For some programs with longer washing times and higher heating temperatures, such as intensive wash and steam wash programs, the machine will dissipate heat faster and cool down slower after the heating temperature rises to 60-70 degrees Celsius.
[0005] Heating can improve cleaning results. Warm water can better activate the cleaning agent, making its molecules more active and easier to penetrate into the stains. At the same time, warm water also helps to soften some stubborn stains, such as oil stains or food residue, making them easier to break down and remove.
[0006] Secondly, heating also helps improve overall cleaning efficiency. Compared to cold water, warm water can reach the appropriate washing temperature faster, thus shortening the waiting time. In addition, warm water can better maintain a stable temperature environment during the washing process, enabling the dishwasher to work continuously and efficiently.
[0007] For example, when washing greasy dishes, if you use cold water, the grease may solidify or adhere to the surface and be difficult to remove. However, if you use warm water, the grease will be softened and broken down more easily, allowing for thorough cleaning.
[0008] Therefore, the existing control methods for dishwashers cannot adapt to different weather conditions and voltage differences in different countries or regions. This causes the dishwasher to misjudge the washing and heating stage and directly switch to the cold water washing mode, thereby reducing the washing effect. Summary of the Invention
[0009] The present invention aims to solve the above-mentioned technical problems, namely, to solve the problem that the existing dishwasher control method cannot be adapted to the use in different countries or regions with different weather environments and voltages, causing the dishwasher to make malfunctions and misjudge during the washing and heating stage, and directly enter the cold water washing mode, thereby reducing the washing effect.

[0020] Determine whether the first heating efficiency is less than the first set heating efficiency;
[0021] If the first heating efficiency is determined to be less than the first set heating efficiency, then a heating fault is determined to exist.
[0022] In the preferred embodiment of the control method for the dishwasher described above, after determining that a heating fault exists, the heating process is skipped, a cold water washing mode is executed, and a heating fault alarm code is stored.
[0023] In the preferred embodiment of the control method for the dishwasher described above, when it is determined that the first heating efficiency is greater than the first set heating efficiency, the heating is determined to be normal and the washing process continues normally.

[0026] The second heating efficiency during the heating phase of the dishwasher's washing process is acquired in real time.
[0027] Determine whether the second heating efficiency is less than the second set heating efficiency;
[0028] If the second heating efficiency is determined to be less than the second set heating efficiency, then a heating fault is determined to exist.
[0029] In the preferred embodiment of the control method for the dishwasher described above, after determining that a heating fault exists, the heating process is skipped, a cold water washing mode is executed, and a heating fault alarm code is stored.
[0030] In the preferred embodiment of the control method for the dishwasher described above, when it is determined that the second heating efficiency is greater than the second set heating efficiency, the heating is determined to be normal and the washing process continues normally.

Attached Figure Description
[0036] The preferred embodiments of the present invention are described below with reference to the accompanying drawings, in which:
[0037] Figure 1 This is a flowchart of the steps of a control method for a dishwasher according to the present invention. Detailed Implementation
[0038] Preferred embodiments of this application will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of this application and are not intended to limit the scope of protection of this application. For example, although the steps are described in a sequential order in the following embodiments, those skilled in the art will understand that, in order to achieve the effects of this embodiment, different steps need not be executed in such an order; they can be executed simultaneously (in parallel) or in a reverse order, and these simple variations are all within the scope of protection of this application.
[0039] Existing dishwasher control methods are compatible with multiple models, and different models of dishwashers may be exported to different countries or regions.
[0040] However, due to significant differences in ambient temperature between different countries and regions, or even different seasons within the same country, the heating process of a dishwasher can be affected. For example, in cold seasons or countries and regions with consistently low temperatures, the ambient temperature can accelerate the dishwasher's heat dissipation, resulting in a slower temperature rise during the heating process.
[0041] Some dishwashers used in the Americas generally use 120V voltage, so they heat up slowly. For some programs with longer washing times and higher heating temperatures, such as intensive wash and steam wash programs, the machine will dissipate heat faster and cool down slower after the heating temperature rises to 60-70 degrees Celsius.
[0042] Heating can improve cleaning results. Warm water can better activate the cleaning agent, making its molecules more active and easier to penetrate into the stains. At the same time, warm water also helps to soften some stubborn stains, such as oil stains or food residue, making them easier to break down and remove.
[0043] Secondly, heating also helps improve overall cleaning efficiency. Compared to cold water, warm water can reach the appropriate washing temperature faster, thus shortening the waiting time. In addition, warm water can better maintain a stable temperature environment during the washing process, enabling the dishwasher to work continuously and efficiently.
[0044] For example, when washing greasy dishes, if you use cold water, the grease may solidify or adhere to the surface and be difficult to remove. However, if you use warm water, the grease will be softened and broken down more easily, allowing for thorough cleaning.
[0045] Therefore, the existing control methods for dishwashers cannot adapt to different weather conditions and voltage differences in different countries or regions. This causes the dishwasher to misjudge the washing and heating stage and directly switch to the cold water washing mode, thereby reducing the washing effect.
[0046] To address the above problems, the present invention provides a control method for a dishwasher, comprising the following steps: Step S1: acquiring the current operating environment information and / or power supply information of the dishwasher; Step S2: determining whether the dishwasher is being used in a low-temperature environment and / or under low voltage conditions based on the current operating environment information and / or power supply information; Step S3: when it is determined that the dishwasher is being used in a low-temperature environment and / or under low voltage conditions, automatically matching a first heating fault judgment mode adapted to low-temperature environment and / or low voltage conditions.
[0047] The control method for a dishwasher of the present invention acquires the current operating environment information and / or power supply information of the dishwasher, and determines whether the dishwasher is used in a low temperature environment and / or low voltage condition based on the current operating environment information and / or power supply information. If so, it automatically matches a first heating fault judgment mode adapted to use in a low temperature environment and / or low voltage condition. The appropriate heating fault judgment can be adjusted according to the actual use of the dishwasher, so that false judgments will not occur and the dishwasher can be prevented from quickly entering the cold water washing mode in order to improve the washing effect.
[0048] The following is combined Figure 1 This application provides a detailed description of a control method for a dishwasher, a dishwasher, and a computer storage medium.
[0049] like Figure 1 As shown, in a first aspect, the present invention provides a control method for a dishwasher, the control method comprising the following steps:
[0050] Step S1: Obtain the current operating environment information and / or energy supply information of the dishwasher;
[0051] Step S2: Based on the current environmental information and / or power supply information, determine whether the dishwasher is being used in a low-temperature environment and / or under low voltage conditions;
[0052] Step S3: When it is determined that the dishwasher is used in a low temperature environment and / or low voltage, the first heating fault judgment method adapted to use in a low temperature environment and / or low voltage is automatically matched.
[0053] When the above technical solution is adopted, by obtaining the current usage environment information and / or power supply information of the dishwasher, and based on the current usage environment information and / or power supply information, it is determined whether the dishwasher is used in a low temperature environment and / or low voltage. If so, the first heating fault judgment method adapted to use in a low temperature environment and / or low voltage is automatically matched. The appropriate heating fault judgment can be adjusted according to the actual usage of the dishwasher, so no misjudgment will occur, and the dishwasher can be prevented from quickly entering the cold water washing mode in order to improve the washing effect.
[0054] In this embodiment, obtaining the current operating environment information of the dishwasher includes: the current ambient temperature parameter of the country and / or region where the dishwasher is used. Power supply information includes: the voltage value supplied in the country and / or region where the dishwasher is used.
[0055] Specifically, dishwashers automatically assess heating efficiency during washing. When the heating efficiency is lower than the set efficiency, it's assumed there's a heating malfunction, and the dishwasher will automatically switch to a cold water wash mode. However, in cases of heavy grease buildup, a cold water wash may not be effective at cleaning. In some colder regions, the water temperature entering the dishwasher is lower, which can also affect heating efficiency. The dishwasher might then interpret this as a heating malfunction and switch to a cold water wash mode, even though the actual heating isn't faulty but rather slow due to the low water temperature. For example, in Mohe, Heilongjiang province, winter temperatures can drop to around -40 degrees Celsius, significantly lower than in southern my country, resulting in lower heating efficiency and causing a misjudgment.
[0056] Another situation arises because in some countries the voltage is 120 volts, lower than my country's 240 volts. This can reduce the washing and heating efficiency of dishwashers, leading to misjudgments. The dishwasher might automatically switch to a cold water wash mode, but this is insufficient for cleaning heavily soiled surfaces. For example, in urban areas of the United States, where the voltage is 120 volts, the slow heating efficiency of dishwashers can cause misjudgments.
[0057] The control method for a dishwasher in this application first obtains the current operating environment information and / or power supply information of the dishwasher, namely the country and / or region and / or voltage where the dishwasher is located, and matches a suitable first heating fault judgment method according to the country and / or region and / or voltage. The appropriate heating fault judgment can be adjusted according to the actual use of the dishwasher, so that false judgments will not occur and the dishwasher can be prevented from quickly entering the cold water washing mode in order to improve the washing effect.
[0058] More specifically, the dishwasher is equipped with a controller that connects to a wireless network, obtains the dishwasher's location, and, based on that location, receives weather information to determine if the water temperature entering the dishwasher is too low. When a low water temperature is detected (i.e., a low-temperature environment), the controller automatically selects the appropriate primary heating fault diagnosis method to assess the dishwasher's heating and washing process, avoiding the use of other unsuitable methods and thus preventing misdiagnosis. The dishwasher also has a voltmeter to measure the voltage entering the dishwasher. When the voltage is 120 volts, it is considered low voltage, and the controller automatically selects the appropriate primary heating fault diagnosis method to assess the dishwasher's heating and washing process, avoiding the use of other unsuitable methods and thus preventing misdiagnosis.
[0059] It should be noted that the controller mentioned above is an existing controller, and the specific installation method is also existing, so it will not be described in detail here.
[0060] It should be noted that the voltmeter mentioned above is an existing voltmeter, and the specific installation method is also existing, so it will not be described in detail here.
[0061] like Figure 1 As shown, in the preferred embodiment of the control method for the dishwasher described above, step S3: when it is determined that the dishwasher is used in a low-temperature environment and / or low-voltage condition, automatically matching the first heating fault judgment method adapted to use in a low-temperature environment and / or low-voltage condition includes the following steps:
[0062] Step S31: Obtain the first heating efficiency during the heating phase of the dishwasher's washing process in real time;
[0063] Step S32: Determine whether the first heating efficiency is less than the first set heating efficiency;
[0064] Step S33: When it is determined that the first heating efficiency is less than the first set heating efficiency, it is determined that there is a heating fault.
[0065] In the preferred embodiment of the control method for the dishwasher described above, after determining that a heating fault exists, step S34 is executed: skip the heating process, execute the cold water washing mode, and store the heating fault alarm code.
[0066] Specifically, during the washing cycle, the dishwasher acquires the first heating efficiency of the water in real time. This first heating efficiency is, for example, heating the water to 1 degree Celsius every 2 minutes, and the first set heating efficiency is, for example, heating the water to 1.5 degrees Celsius every 2 minutes. If, within the same time frame, the heating temperature in the first heating efficiency is lower than the heating temperature in the first set heating efficiency, a heating fault is determined. The dishwasher can then choose to execute a cold water wash mode or pause the wash cycle and issue a buzzer alarm and text prompts, allowing the user to manually select the appropriate action. This first heating fault detection method is suitable for use in low-temperature environments and / or low-voltage conditions, preventing false heating judgments during washing that could lead to a cold water wash mode and consequently poor washing results.
[0067] Specifically, dishwashers can also determine if there is a heating malfunction by observing the duration of water heating during the washing program. When the dishwasher is running, the user selects a washing program, and some dishes require longer washing times. For example, a 120-minute washing program first fills the tank and heats the water, with a preset heating time of approximately 30 minutes to reach the desired temperature. However, due to environmental factors and / or low voltage conditions, the actual heating time may be 35 minutes to reach the required water temperature, exceeding the preset heating time. In this case, a heating malfunction can be identified, and the dishwasher can either execute a cold water wash mode or pause the washing process and issue a buzzer alarm and text prompts for the user to manually adjust the settings.
[0068] In the preferred embodiment of the control method for the dishwasher described above, when it is determined that the first heating efficiency is greater than the first set heating efficiency, the heating is determined to be normal and the washing process continues normally.
[0069] Specifically, when the first heating efficiency is, for example, heating water to a temperature of 1.2 degrees Celsius in 2 minutes, and the first set heating efficiency is, for example, heating water to a temperature of 1 degree Celsius in 2 minutes, the heating temperature in the first heating efficiency is greater than the heating temperature in the first set heating efficiency within the same time period. At this time, it is determined that the heating is normal, and the dishwasher continues to perform the washing operation normally.
[0070] In the above embodiment, the dishwasher is equipped with multiple heating elements and a temperature sensor. The heating elements are communicatively connected to a controller to control their heating, ensuring that the water entering the dishwasher is heated to a set temperature. The temperature sensor is also communicatively connected to the controller to acquire the temperature value of the water entering the dishwasher, allowing the controller to execute the appropriate washing mode based on the temperature value, such as continuing with a hot water wash or switching to a cold water wash mode.
[0071] It should be noted that the heating components mentioned above are existing heating components, and the specific installation method is also existing, so it will not be described in detail here.
[0072] It should be noted that the temperature sensor mentioned above is an existing temperature sensor, and the specific installation method is also existing, so it will not be described in detail here.
[0073] like Figure 1 As shown, in the preferred embodiment of the control method for the dishwasher described above, the control method further includes: step S4: when it is determined that the dishwasher is not used in a low-temperature environment and / or at low voltage, a second heating fault determination method is executed. This step S4: when it is determined that the dishwasher is not used in a low-temperature environment and / or at low voltage, the second heating fault determination method is executed, which includes the following steps:
[0074] Step S41: Obtain the second heating efficiency during the heating phase of the dishwasher's washing process in real time;
[0075] Step S42: Determine whether the second heating efficiency is less than the second set heating efficiency;
[0076] Step S43: When it is determined that the second heating efficiency is less than the second set heating efficiency, it is determined that there is a heating fault.
[0077] In the preferred embodiment of the control method for the dishwasher described above, after determining that a heating fault exists, the heating process is skipped, a cold water washing mode is executed, and a heating fault alarm code is stored.
[0078] Specifically, during the washing cycle, the dishwasher acquires the second heating efficiency of the water in real time. This second heating efficiency is, for example, heating the water to 1 degree Celsius every 3 minutes, and the second set heating efficiency is, for example, heating the water to 1.5 degrees Celsius every 3 minutes. If, within the same time frame, the heating temperature in the second heating efficiency is lower than the heating temperature in the second set heating efficiency, a heating fault is determined. The dishwasher can then choose to execute a cold water wash mode or pause the wash cycle and issue a buzzer alarm and text prompts, allowing the user to manually select the appropriate action. This second heating fault detection method is suitable for dishwashers used in environments other than low temperatures and / or low voltage conditions, preventing misjudgments during washing that could lead to a cold water wash mode and consequently poor washing results.
[0079] In the preferred embodiment of the control method for the dishwasher described above, step 44: when it is determined that the second heating efficiency is greater than the second set heating efficiency, it is determined that the heating is normal and the washing process continues normally.
[0080] Specifically, when the second heating efficiency is, for example, heating the water temperature by 2 degrees Celsius every 3 minutes, and the second set heating efficiency is, for example, heating the water temperature by 1.5 degrees Celsius every 3 minutes, under the same time, the heating temperature in the second heating efficiency is greater than the heating temperature in the second set heating efficiency. At this time, it is determined that the heating is normal, and the dishwasher continues to perform the washing operation normally.
[0081] In a second aspect, the present invention also provides a dishwasher, which includes a controller configured to execute the aforementioned control method for a dishwasher. When employing the above technical solution, the dishwasher utilizes a control method for a dishwasher that first acquires information about the current operating environment and / or power supply, i.e., the country and / or region and / or voltage where the dishwasher is located. Based on the country and / or region and / or voltage, a suitable first heating fault judgment method is matched. This allows for adjustment of the heating fault judgment according to the actual usage of the dishwasher, thus preventing misjudgments and avoiding the dishwasher from quickly entering a cold water washing mode, thereby improving the washing effect.
[0082] Thirdly, the present invention also provides a computer storage medium storing a computer program that, when executed, enables the above-described control method for a dishwasher.
[0083] When the above technical solution is adopted, the computer storage medium can realize the above control method for the dishwasher. First, it obtains the current usage environment information and / or power supply information of the dishwasher, that is, the country and / or region and / or voltage where the dishwasher is located. Then, according to the country and / or region and / or voltage, it matches a suitable first heating fault judgment method. The appropriate heating fault judgment can be adjusted according to the actual use of the dishwasher, so no misjudgment will occur. It can prevent the dishwasher from quickly entering the cold water washing mode, so as to improve the washing effect.
[0084] Computer-readable media includes both computer storage media and communication media, encompassing any medium that facilitates the transfer of a computer program from one location to another. Storage media can be any available medium accessible to a computer. By way of example and not limitation, such computer-readable media may include RAM, ROM, EEPROM, CD=ROM or other optical disc storage, magnetic disk storage or other magnetic storage devices, or any other medium that can be used to carry or store desired program code in the form of instructions or data structures and is accessible to a computer. Any connection is also properly referred to as computer-readable media.
