Description

Technical Field

[0001] This invention belongs to the field of home appliance technology, and more specifically, relates to a control method for a dishwasher and the dishwasher itself. Background Technology

[0002] In modern life, dishwashers have become an indispensable household appliance. With continuous technological advancements, the functions of dishwashers are constantly being enriched and improved. However, adjusting the washing parameters of the currently running washing program to accelerate the washing process remains a challenge.

[0003] During a dishwasher cycle, prolonged washing of lightly soiled dishes can lead to excessive electricity costs. However, simply stopping the running wash cycle will affect the washing results. Failing to address the specific washing program type can result in a series of adverse effects. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a control method for a dishwasher and a dishwasher in general. If an accelerated washing command is received during the washing program, the currently running washing program is adjusted according to the type of the currently running washing program, the current indoor temperature, and the current electricity usage period to meet the diverse needs of users for the dishwasher.

[0005] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by the present invention is as follows:

[0006] A method for controlling a dishwasher,

[0007] If an accelerated washing command is received during the first washing program running with the first washing parameters,

[0008] Determine whether the first washing program meets the conditions for accelerated washing.

[0009] If so, adjust the first washing parameters of the first washing program and run the first washing program according to the adjusted second washing parameters.

[0010] Furthermore, if it is determined that the first washing program does not meet the conditions for accelerated washing,

[0011] Then continue to determine whether the current environmental information meets the set conditions.

[0012] If the current environmental information is determined to meet the set conditions, the first washing parameters of the first washing program are adjusted, and the first washing program is run according to the adjusted third washing parameters.

[0013] Furthermore, the first washing parameters include at least washing time, rinsing time, and motor speed;

[0014] Adjust the first washing parameters by reducing the washing time by ΔT2 and / or reducing the rinsing time by ΔT1 and / or increasing the motor speed by Δn to obtain the third washing parameters;

[0015] The first washing program is run with the third washing parameters.

[0016] Furthermore, if it is determined that the conditions for accelerated washing are not currently met,

[0017] Then continue to determine whether the current electricity consumption period is a peak period.

[0018] If it is determined that the current electricity consumption period is a peak period, then the first washing parameter of the first washing program is adjusted, and the first washing program is run according to the adjusted fourth washing parameter.

[0019] Furthermore, the first washing parameter also includes the heating temperature;

[0020] If the current electricity consumption period is determined to be a peak period...

[0021] Adjust the first washing parameters by reducing the heating temperature by Δt1 and / or reducing the rinsing time by ΔT1 to obtain the fourth washing parameters;

[0022] The first washing program is run according to the fourth washing parameters.

[0023] Furthermore, if the first washing program meets the accelerated washing conditions,

[0024] Adjust the first washing parameters by reducing the heating temperature by Δt1 and / or reducing the washing time by ΔT1 to obtain the second washing parameters;

[0025] Run the first washing program according to the second washing parameters.

[0026] Furthermore, before determining whether the first washing program meets the accelerated washing condition, it is determined whether the remaining running time of the first washing program is greater than or equal to the running time of the second washing program.

[0027] If so, end the first washing program and execute the second washing program.

[0028] Furthermore, the second washing program includes a fifth washing parameter, and the second washing program is run according to the fifth washing parameter;

[0029] During the second washing program, if it is determined that the current environmental information does not meet the set conditions and the current power consumption period is not a peak period,

[0030] Then adjust the fifth washing parameter of the second washing program and run the second washing program according to the adjusted sixth washing parameter.

[0031] Furthermore, the fifth washing parameter includes at least the first washing time and the first rinsing time.

[0032] Adjusting the fifth washing parameter by reducing the first washing time by ΔT2 and / or reducing the first rinsing time by ΔT1, yields the sixth washing parameter;

[0033] Run the second washing program according to the sixth washing parameters.

[0034] A dishwasher employing the dishwasher control method described above.

[0035] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art.

[0036] 1. Adapt to different types of programs and adjust the washing parameters of the washing program accordingly to ensure cleaning effect while accelerating washing.

[0037] 2. Based on environmental information, the motor speed is adjusted accordingly to enhance the impact of the water flow, while the temperature is lowered, thereby accelerating the washing process and better removing stains from the dishes.

[0038] 3. While ensuring washing effectiveness, it reduces water and electricity consumption, achieving efficient resource utilization. This can reduce energy consumption to a certain extent and play a positive role in environmental protection.

[0039] The specific embodiments of the present invention will now be described in further detail with reference to the accompanying drawings. Attached Figure Description

[0040] The accompanying drawings, as part of this invention, are used to provide a further understanding of the invention. The illustrative embodiments and descriptions of the invention are used to explain the invention, but do not constitute an undue limitation of the invention. Obviously, the drawings described below are merely some embodiments, and those skilled in the art can obtain other drawings based on these drawings without creative effort. In the drawings:

[0042] Figure 2 This is a flowchart of a dishwasher control method (II).

[0043] It should be noted that these accompanying drawings and textual descriptions are not intended to limit the scope of the invention in any way, but rather to illustrate the concept of the invention to those skilled in the art by referring to specific embodiments. Detailed Implementation

[0044] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting this invention.

[0046] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," "contact," and "communication" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0047] When washing dishes with existing dishwasher programs, the degree of soiling varies. Using the same program for lightly soiled dishes as for dishes with varying degrees of soiling often results in wasted water and electricity. The accelerated wash function, however, can adjust washing parameters individually for lightly soiled dishes, reducing water and electricity consumption while maintaining washing effectiveness, thus achieving efficient resource utilization. This reduces energy consumption to some extent and plays a positive role in environmental protection. For lightly soiled dishes requiring faster washing, the accelerated wash function can significantly shorten washing time. Clean dishes can be obtained quickly without waiting for the entire standard wash cycle to complete, improving efficiency. Using the same wash program for dishes with different levels of soiling can over-wash lightly soiled dishes, affecting their lifespan. The accelerated wash function adjusts the washing intensity and method according to the characteristics of lightly soiled dishes, reducing wear and tear and protecting the appearance and quality of the dishes. The accelerated wash function is simple and convenient to operate, allowing users to easily learn how to use it. Whether it's the elderly or children, they can quickly master its operation, bringing more convenience to family life.

[0048] A method for controlling a dishwasher, such as Figure 1 As shown, a control method flow chart for a dishwasher Figure 1 During the first washing program of the dishwasher, if an accelerated washing command is received, it is determined whether the currently running first washing program meets the accelerated washing conditions.

[0049] Among them, the accelerated washing conditions include at least one washing program that is a pre-stored type of washing program as the first washing program.

[0050] When the first washing program is not a pre-stored type of washing program, but an accelerated wash is required, and the remaining run time of the first washing program is greater than the set time, adjust the first washing parameters of the first washing program and run the first washing program according to the adjusted washing parameters. Ensure that there is sufficient time for adjustment during the first washing program and that the program runs for at least the set time after adjustment.

[0051] The pre-stored types include cleaning programs for easy-to-wash tableware such as glass wash, fruit and vegetable wash, baby wash, and energy-saving wash.

[0052] Glass cleaner is specifically designed for glass products, preventing scratches on the glass surface during the cleaning process and maintaining the glass's transparency and gloss.

[0053] Fruit and vegetable wash is designed to meet the cleaning needs of fruits and vegetables. It can effectively remove pesticide residues, dirt, and impurities from the surface of fruits and vegetables without damaging them, ensuring that fruits and vegetables are safer and more hygienic.

[0054] Baby and maternity wash products are designed with the special needs of infants and pregnant women in mind. They employ gentler cleaning methods, avoiding the use of harsh detergents to ensure that the washed tableware is harmless to the health of babies and pregnant women.

[0055] Energy-saving washes prioritize energy conservation and environmental protection. By optimizing washing parameters, they reduce water and electricity consumption, saving household expenses while also contributing to environmental protection.

[0056] The pre-stored programs have undergone rigorous testing and optimization to ensure that the tableware is not damaged during the cleaning process, while also guaranteeing the cleaning effect.

[0057] For situations where tableware needs to be used urgently, the accelerated wash function can significantly shorten the washing time of pre-set programs. Saving time is crucial in busy modern life. The accelerated wash function can complete the dishwashing task in a shorter time. It improves the washing efficiency of pre-set programs without compromising cleaning effectiveness. By optimizing washing parameters and processes, increasing water flow speed and detergent action, it can remove stains and bacteria from tableware more quickly.

[0058] If the currently running first washing program is a pre-stored type, adjust the first washing parameters of the first washing program and run the first washing program according to the adjusted second washing parameters. If it is determined that the first washing program is not a pre-stored type,

[0059] The system then continues to determine if the current environmental information meets the set conditions. This environmental information includes at least the indoor temperature. It checks if the indoor temperature is lower than the set value. If it is, the first washing parameter of the first washing program is adjusted, and the first washing program is run according to the adjusted third washing parameter. The temperature setpoint can be customized according to different indoor environments, for example, it can be set to 18℃-25℃. The purpose of determining if the current indoor temperature is lower than the set value is to allow the dishwasher to adapt to environmental changes. Different indoor temperatures can cause stains on dishes to solidify and become more difficult to wash if not washed promptly. For example, in winter, due to the low temperature, grease on dishes solidifies quickly. To accelerate washing dishes in this condition, the washing time, heating temperature, and motor speed of the washing program need to be adjusted.

[0060] Therefore, the first washing parameters should include at least the washing time, rinsing time, and motor speed;

[0061] Adjust the first washing parameters by reducing the washing time by △T2 and / or reducing the rinsing time by △T1 and / or increasing the motor speed by △n to obtain the third washing parameters;

[0062] Run the first washing program with the third washing parameters.

[0063] If the current indoor temperature is determined to be higher than the set value.

[0064] Then continue to determine whether the current electricity consumption period is a peak period.

[0065] If the current electricity consumption period is determined to be a peak period, the first washing parameter of the first washing program is adjusted, and the first washing program is run according to the adjusted fourth washing parameter.

[0066] Environmental information may also include indoor humidity. The system determines whether the indoor humidity is below a set value. If the current indoor temperature is below the set value, the system adjusts the first washing parameters of the first washing program and runs the first washing program according to the adjusted third washing parameters. The set values ​​can be customized based on different indoor environments.

[0067] Electricity consumption periods are categorized into peak, off-peak, and low-peak periods. For example, household electricity consumption periods are typically divided into the following: Peak periods: generally during weekday daytime, roughly from 8 am to 10 pm. During this time, most family members are out working or studying, but high-power appliances such as air conditioners and water heaters may be running because someone is home or they have already turned them on. After get off work and in the evening, various electrical appliances such as televisions, computers, and lighting are widely used, causing peak household electricity demand. For example, in hot summer months, turning on the air conditioner when returning home in the evening significantly increases electricity consumption. Weekends and holidays may also see peak electricity consumption periods during the day and evening, as family members spend more time at home, increasing the frequency of appliance use.

[0068] Off-peak hours: For example, from around 11 PM to 7 AM. During this time, most family members are asleep, and the use of electrical appliances is minimal, resulting in a low demand for electricity. Only essential appliances such as refrigerators may continue to run, but their power consumption is relatively small. Electricity prices are often lower during off-peak hours, and some energy-conscious families may take advantage of this time to carry out pre-planned electricity-consuming activities.

[0069] Off-peak hours: These are between peak and off-peak hours, generally around 7:00 to 8:00 AM and 10:00 to 11:00 PM. During this period, household electricity demand is relatively stable, neither as high as during peak hours nor as low as during off-peak hours.

[0070] The first washing parameter includes the heating temperature. If the current power consumption period is determined to be a peak period, the first washing parameter is adjusted by reducing the heating temperature by Δt1 and / or reducing the rinsing time by ΔT1, resulting in the fourth washing parameter. The first washing program is then run according to the fourth washing parameter. Reducing the heating temperature and rinsing time can lower the peak power demand of the dishwasher.

[0071] If the first washing program is a pre-stored type

[0072] Adjust the first washing parameters by reducing the heating temperature by Δt1 and / or reducing the washing time by ΔT1 to obtain the second washing parameters;

[0073] Run the first washing program according to the second washing parameters.

[0074] Among them, reducing the washing time by △T2 and / or reducing the rinsing time by △T1 and / or increasing the motor speed by △n means that the washing time is reduced by △T2 based on the original washing time and rinsing time. Here, △T2 and △T1 represent the amount of change.

[0075] In some solutions of this embodiment, such as Figure 2 As shown, a control method flow chart for a dishwasher Figure 2Before determining whether the first washing program is a pre-stored type, determine whether the remaining running time of the first washing program is greater than or equal to the running time of the second washing program.

[0076] If so, end the first washing cycle and start the second washing cycle.

[0077] The total running time of the first washing program is greater than the total running time of the second washing program. Determining whether the remaining running time of the first washing program is greater than or equal to the running time of the second washing program ensures that the remaining running time of the first program allows sufficient time to adjust the washing parameters of the second washing program, and guarantees successful operation of the second washing program after adjustment. If the second washing program successfully runs within the remaining running time of the first washing program, the first washing program ends.

[0078] If it is determined that the remaining running time of the first washing program is less than the running time of the second washing program, then it is further determined whether the remaining running time of the first washing program is greater than or equal to the set time. If so, the washing parameters of the first washing program are adjusted, and the first washing program is run according to the adjusted washing parameters.

[0079] The second washing program includes the fifth washing parameter, and the second washing program is run according to the fifth washing parameter.

[0080] During the second washing cycle, if it is determined that the current indoor temperature is greater than or equal to the set value and the current electricity consumption period is not a peak period,

[0081] Then adjust the fifth washing parameter of the second washing program, and run the second washing program according to the adjusted sixth washing parameter.

[0082] If the remaining running time of the first washing program is greater than or equal to the running time of the second washing program, the washing time is reduced by ΔT2, the rinsing time is reduced by ΔT1, and the motor speed is increased by Δn, based on the indoor temperature in the environmental information or the current electricity usage period.

[0083] For example, a higher indoor temperature accelerates detergent activity, allowing for a reduction in washing and rinsing times. Higher temperatures also make dishes easier to clean, reducing the need for longer washes and rinses. Conversely, a lower indoor temperature may reduce detergent activity, requiring more careful adjustment of washing parameters to avoid ineffective cleaning due to excessively reduced washing and rinsing times. Secondly, the current electricity usage time is also an important consideration. During off-peak hours, motor speed can be increased to speed up the wash cycle while reducing washing and rinsing times, taking full advantage of lower electricity prices. During peak hours, motor speed can be reduced while increasing washing and rinsing times to avoid putting excessive strain on the power grid.

[0084] Ensure that the adjusted washing parameters will not damage the dishes. To guarantee a clean result, while reducing washing and rinsing times can speed up the process, it shouldn't come at the expense of cleaning effectiveness. Conduct some tests after adjusting the parameters to ensure the dishes are thoroughly cleaned.

[0085] In some embodiments of this invention, the total running time of the first washing program is greater than the total running time of the second washing program. During the execution of the second washing program, the washing parameters of the second washing program can be adjusted to achieve a second accelerated washing. Adjusting the washing parameters of the second washing program includes adjusting them if the current indoor temperature is greater than or equal to a set value and the current electricity consumption period is not a peak period. This avoids excessive electricity consumption while further accelerating the washing time and ensuring the cleaning effect.

[0086] The fifth washing parameter should include at least the first washing time and the first rinsing time.

[0087] Adjust the fifth washing parameter by reducing the first washing time by △T2 and / or reducing the first rinsing time by △T1 to obtain the sixth washing parameter;

[0088] Run the second washing program according to the sixth washing parameter.

[0089] In some solutions of this embodiment, in addition to adjusting the washing parameters according to the current indoor temperature and the current electricity usage period, adjustments can also be made according to the current dirtiness of the tableware, or according to the number of tableware, user-defined settings, etc.

[0090] If the dishwasher contains a small number of dishes, the washing time, water usage, and detergent amount can be reduced accordingly. This saves resources and avoids damage to the dishes caused by over-washing.

[0091] For dishes with only minor stains, reduce washing time and water usage to save energy and speed up cleaning. When the stains are more severe, increase motor speed, extend washing time, and raise water temperature.

[0092] In some embodiments of this invention, at least a third washing program is included. During operation, if an accelerated washing command is received, the third washing program also performs accelerated washing according to the method for adjusting washing parameters. Furthermore, the fifth washing parameter of the second washing program can be determined based on the first washing parameter of the first washing program.

[0093] In some embodiments of this invention, during the first washing program, a control operation is performed in response to the dishwasher to accelerate the washing process. The control operation is at least controlled by buttons on the dishwasher control interface. When the user clicks a control button, the dishwasher adjusts the washing parameters to accelerate the washing process.

[0094] In some embodiments of this invention, if the dishwasher's control interface includes a touch-sensitive display interface, it can be configured such that after the washing program runs for a set time, for example, 2-5 seconds, the display interface prompts whether to perform accelerated washing. If no control operation for accelerated washing is received after waiting for the set time, accelerated washing is not performed by default.
