Technical Field

[0001] This application belongs to the technical field of dishwashers, and particularly relates to a dishwasher control method, device and dishwasher. Background Art

[0002] The wide application of dishwashers brings great convenience to people's daily lives. During the entire washing process, a dishwasher needs to control the start and stop states of multiple loads. For example, it switches the start and stop states of a drain pump, a residual water pump, a washing pump, etc. Usually, before the washing starts and after the main washing stops, the drain pump (including the residual water pump) works according to a fixed operating time, and other loads are in a stopped state when the drain pump is working. There will be a situation where the drain pump continues to work when there is no water in the dishwasher. Since the installation position of the drain pump is close to the inner tank, when it starts to operate, low-frequency noise is transmitted through vibration and amplified by the inner tank cavity, so the propagation distance is far and the sound is loud, bringing a bad user experience. Summary of the Invention

[0056] To make the objectives, technical solutions and advantages of the present application clearer, the technical solutions of the present application will be described in detail below. Apparently, the described embodiments are only a part rather than all of the embodiments of the present application. Based on the embodiments in the present application, all other implementation manners obtained by those of ordinary skill in the art without creative efforts shall fall within the scope protected by the present application.

[0057] Figure 1 As shown in the flowchart of the dishwasher control method provided in an embodiment of the present application, Figure 1 the dishwasher control method includes:

[0058] S11: After power-on, obtain the working records of each load during the last operation of the dishwasher;

[0059] In this embodiment, the working records of each load during the last operation of the dishwasher can be obtained from the non-volatile area of the internal controller of the dishwasher.

[0060] S12: Judge whether the working states of each load are normal according to the working records of each load. If the working states of all loads are normal, execute S13; otherwise, execute S14;

[0061] S13: Control the drain pump to run for a first preset duration;

[0062] S14: Control the drain pump to run for a second preset duration, and the first preset duration is less than the second preset duration.

[0063] In this embodiment, the second preset duration can be the working duration of the drain pump controlled by a traditional dishwasher. The first preset duration is less than the second preset duration, and the specific value can be set according to the actual use environment.

[0064] Since the working states of each load of the dishwasher are normal in most cases, the purpose of reducing the running time of the drain pump can be achieved.

[0065] During the entire washing process of a traditional dishwasher, multiple loads switch between start and stop states according to a fixed working time. For example, before the start of washing and after the main wash stops, the drain pump or the residual water pump will work according to a fixed running time. There may be a situation where the drain pump or the residual water pump still continues to work when there is no residual water in the dishwasher. Since the installation position of the drain pump or the residual water pump is close to the inner liner, when it starts to run, low-frequency noise is transmitted through vibration, which is amplified by the inner liner cavity, so the propagation distance is far and the sound is loud, bringing a bad user experience to the user.

[0066] In this embodiment, the dishwasher control method includes obtaining the working records of each load during the last operation of the dishwasher after startup; judging whether the working states of each load are normal according to the working records of each load; if the working states of each load are all normal, controlling the drain pump to operate for a first preset duration; otherwise, controlling the drain pump to operate for a second preset duration, where the first preset duration is less than the second preset duration. Since the operation duration of the drain pump is reduced when the working states of each load are normal, the working time of the drain pump can be shortened, thereby solving the problem of noise generated by the long-term operation of the drain pump when there is no remaining water in the dishwasher, improving the sound quality of the dishwasher, and enhancing the user experience.

[0067] Figure 2 The flowchart of the dishwasher control method provided by another embodiment of this application is as Figure 2 shown, and this dishwasher control method includes:

[0068] S21: Obtain the working time and operating power of the drain pump;

[0069] S22: Calculate the first drainage volume of the drain pump according to the working time and operating power of the drain pump;

[0070] S23: If the first drainage volume is the same as the water inlet volume, it is determined that the drain pump is working normally.

[0071] In this embodiment, the water inlet volume can be determined according to the working time and opening degree of the water inlet valve, or can be determined according to the fixed water inlet volume corresponding to the operating mode during the last operation.

[0072] S24: If the first drainage volume is not the same as the water inlet volume, it is determined that the drain pump is working abnormally, and control the drain pump to operate for a second preset duration.

[0073] As Figure 3 shown, if the load further includes a waste water pump, this dishwasher control method includes:

[0074] S31: Obtain the working time and operating power of the waste water pump;

[0075] S32: Calculate the second drainage volume of the waste water pump according to the working time and operating power of the waste water pump;

[0076] S33: If the sum of the first drainage volume and the second drainage volume is the same as the water inlet volume, it is determined that the drain pump and the waste water pump are working normally.

[0077] S34: If the sum of the first drainage volume and the second drainage volume is not the same as the water inlet volume, it is determined that the drain pump and the waste water pump are working abnormally, and control the drain pump to operate for a second preset duration.

[0078] As Figure 4 shown, the load includes a water inlet valve and a drain valve, and this dishwasher control method includes:

[0079] S41: Obtain the opening degree and running time of the water inlet valve;

[0080] S42: Calculate the water inflow based on the opening degree and running time of the water inlet valve;

[0081] S43: Obtain the opening degree and running time of the drain valve;

[0082] S44: Calculate the water drainage based on the opening degree and running time of the drain valve;

[0083] S45: If the water inflow is the same as the water drainage, determine that the water inlet valve and the drain valve are working properly.

[0084] S46: If the water inflow is not the same as the water drainage, determine that the water inlet valve and the drain valve are working abnormally, and control the drain pump to run for a second preset duration.

[0085] As Figure 5 shown, the load includes a washing pump. The dishwasher control method includes:

[0086] S51: Obtain the actual operating parameters of the washing pump. The operating parameters of the washing pump include the running time and running power of the washing pump;

[0087] S52: If the actual operating parameters of the washing pump meet the operating parameter requirements of the washing pump during the previous run, determine that the washing pump is working properly;

[0088] The operating parameter requirements of the washing pump during the previous run include the running time requirement and running power requirement of the washing pump. If the actual running time and running power of the washing pump meet the running time requirement and running power requirement of the washing pump, the operating parameter requirements of the washing pump during the previous run can be obtained through the control logic generated by the controller in the dishwasher.

[0089] S53: If the actual operating parameters of the washing pump do not meet the operating parameter requirements of the washing pump during the previous run, determine that the washing pump is working abnormally, and control the drain pump to run for a second preset duration.

[0090] As Figure 6 shown, the load includes a heating plate. The dishwasher control method includes:

[0091] S61: Obtain the actual operating parameters of the heating plate. The operating parameters of the heating plate include the heating time and heating power of the heating plate;

[0092] S62: If the actual operating parameters of the heating plate meet the operating parameter requirements of the heating plate during the previous run, determine that the heating plate is working properly;

[0093] S63: If the actual operating parameters of the heating plate do not meet the requirements of the operating parameters of the heating plate during the previous operation, it is determined that the heating plate is malfunctioning, and the drain pump is controlled to operate for a second preset duration.

[0094] In this embodiment, it further includes:

[0095] Detect whether the dishwasher was powered off during a pause during the previous operation;

[0096] In this embodiment, detecting whether the dishwasher was paused during the previous operation can be achieved by detecting whether the pause button was pressed, or by checking whether the door was opened during the previous operation, etc., to determine whether there was a pause during the operation of each load during the previous operation.

[0097] If so, control the drain pump to operate for a second preset duration.

[0098] If all the above loads (drain pump, residual water pump, inlet valve, drain valve, washing pump, heating plate) are working properly, control the drain pump to operate for a first preset duration. If the dishwasher had a pause during the previous operation but was not powered off, and the dishwasher completed a normal work process after canceling the pause, control the drain pump to operate for a first preset duration.

[0099] In this embodiment, it further includes:

[0100] After the end of this operation, save the work records of each load, and save the work records of each load in the non-volatile area of the dishwasher controller.

[0101] By saving the operation data of each time, it can provide a data basis for the next use. By saving the records of the operation status of the product in the previous cycle by the main control chip, information such as normal operation, pause during the period, normal operation time of the water pump, and the operation time of the drain pump being less than the standard time are used as feedback to the main control chip for processing, so as to judge and control the operation time of the drain pump after the next cycle is started.

[0102] In this embodiment, by recording and judging the operation status of each main load of the dishwasher and adjusting the operation status of related loads, the generation and transmission of low-frequency noise of the dishwasher are solved, and the overall sound quality of the dishwasher is improved.

[0103] An embodiment of the present invention provides a dishwasher control device, as Figure 7 shown in the functional structure diagram. The dishwasher control device includes:

[0104] An acquisition module 71, configured to acquire the work records of each load of the dishwasher during the previous operation after power-on;

[0105] A judgment module 72, configured to judge whether the working status of each load is normal according to the work records of each load;

[0106] The first control module 73 is configured to control the drain pump to operate for a first preset duration when the working states of all loads during the last operation of the dishwasher are normal.

[0107] The second control module 74 is configured to control the drain pump to operate for a second preset duration when the working state of any one or more loads during the last operation of the dishwasher is abnormal, and the first preset duration is less than the second preset duration.

[0108] In this embodiment, after power-on, the acquisition module acquires the working records of all loads during the last operation of the dishwasher; the judgment module judges whether the working states of all loads are normal according to the working records of all loads; when the working states of all loads during the last operation of the dishwasher are normal, the first control module controls the drain pump to operate for a first preset duration; when the working state of any one or more loads during the last operation of the dishwasher is abnormal, the second control module controls the drain pump to operate for a second preset duration, and the first preset duration is less than the second preset duration, which can shorten the working time of the drain pump, thereby solving the problem of noise generated by the long-term operation of the drain pump when there is no remaining water in the dishwasher, improving the sound quality of the dishwasher, and enhancing the user experience.

[0109] An embodiment of the present invention provides a dishwasher, including:

[0110] At least one processor; and

[0111] A memory communicatively connected to the at least one processor; wherein,

[0112] The memory stores instructions executable by the at least one processor, and the instructions are executed by the at least one processor so that the at least one processor can execute the dishwasher control method described in the above embodiment.

[0113] The working state process of a traditional dishwasher is as Figure 8 , after power-on, the drain pump runs for N seconds fixedly, then the water inlet valve is opened, and after the water inlet ends, the washing pump, the heating plate, the drain pump, and the residual water pump work in sequence. In this solution, since the working time of the drain pump and the residual water pump is fixed, it will cause the drain pump to pump air in vain, resulting in low working efficiency of the dishwasher and generating noise.

[0114] Since the states of the drain pump and other loads of a traditional dishwasher are not recorded, to ensure that there will be no water leakage, water overflow, etc. caused by too much water during the washing process due to residual water in the previous cycle or water that may be added during the process, the drain pump will reserve extra drainage time. Therefore, when there is no water in the inner tank, the drain pump will still continue to work, so obvious low-frequency noise will be generated, affecting the user experience.

[0115] The dishwasher provided by this application has a working state process asFigure 9 After the dishwasher is powered on, obtain the working records of each load during the last operation of the dishwasher after startup. Then, determine whether the working status of each load is normal based on the working records of each load. If the working status of each load is normal, control the drain pump to run for N1 seconds; otherwise, control the drain pump to run for N2 (N2 is greater than N1) seconds, thereby solving the low-frequency "buzzing" resonance noise caused by the long-term empty pumping operation of the drain pump.
