[0022] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the present invention, rather than to limit the present invention. It should also be noted that, for ease of description, only parts related to the present invention, rather than all structures, are shown in the accompanying drawings.
[0023] Figure 1 This is the first flow chart of a laundry equipment control method provided by an embodiment of the present invention. The method of the embodiment of the present invention can automatically adjust the control parameters of the washing machine DC drain pump to ensure that the drain pump can work stably and efficiently under different power grid frequencies. The method can be executed by a laundry equipment control device provided by an embodiment of the present invention, and the device can be implemented in software and / or hardware. The following embodiments will be described by taking the device integrated in a laundry equipment as an example. Figure 1 , the method may specifically include the following steps:
[0024] Step 101: If the current moment is a preset signal collection moment, a sampling unit collects a current signal of a power supply of a laundry device within a preset time period, and determines a current grid frequency corresponding to the power supply at the current moment according to the current signal.
[0025] Among them, the signal collection time is predetermined based on domain big data, etc., and is used to indicate the time when the laundry equipment performs grid frequency detection. For example, the signal collection time may be the time when the laundry equipment is connected to the power supply each time. Or it may be the time when a certain length of time (a week, a month, or half a year, etc.) has passed since the last time the power supply was connected. The laundry equipment in this scheme includes a grid frequency detection device, and the grid frequency detection device includes a sampling unit, which is used to collect the current signal of the power supply of the laundry equipment and send the current signal to the single-chip microcomputer in the laundry equipment for processing. The single-chip microcomputer can determine the grid frequency corresponding to the power supply connected to the laundry equipment based on the received current signal. The preset duration is a duration predetermined based on domain big data and specification information of the laundry equipment, and the preset duration indicates the duration of the acquisition unit collecting the current signal.
[0026] In an optional embodiment, the power grid frequency detection device also includes a power supply zero-crossing detection circuit. In an AC signal, a zero-crossing point is a change point where the voltage periodically changes from positive to negative and then from negative to positive. The power supply zero-crossing detection circuit can accurately detect these zero-crossing points and convert these zero-crossing points into square wave pulse signals. The acquisition unit can receive all square wave pulse signals detected by the power supply zero-crossing detection circuit within a preset time length, and send all square wave pulse signals to the single-chip microcomputer. After receiving the square wave pulse signal, the single-chip microcomputer counts the number of pulse signals within the preset time length, and determines the current power grid frequency based on the number of pulse signals within the preset time length.
[0027] Step 102: Determine control parameters of a drainage pump of the laundry appliance based on the current grid frequency and pre-acquired laundry appliance information.
[0028] Among them, the control parameters at least include an input voltage. The control parameters are used to control or instruct how the drain pump operates. The laundry equipment information includes each target speed corresponding to each washing mode of each washing stage of the laundry equipment. The washing stage includes rinsing, washing and spin drying, etc. The washing mode includes energy-saving mode, normal mode or strong mode, etc. The optimal speed of the drain pump corresponding to different washing stages in different washing modes is different. Under different power grid frequencies, the control parameters that enable the drain pump of the laundry equipment to reach the optimal speed are also different. After determining the power grid frequency, the control parameters corresponding to the optimal speed of the drain pump of the laundry equipment can be determined according to the power grid frequency.
[0029] In an optional implementation, after the current grid frequency is obtained, the input voltages corresponding to the target speeds at the current grid frequency are determined based on the predetermined speed-grid-frequency relationship and the target speeds. The laundry equipment information includes the drainage demand corresponding to each washing mode in each washing stage of the laundry equipment, and the control parameters also include the start-stop parameters of the drainage pump, the start-stop parameters include the start time, the running time and the stop time, and the start-stop parameters corresponding to each drainage demand at the current grid frequency are determined based on the predetermined drainage-grid-frequency relationship and the drainage demand.
[0030] Step 103: Control the laundry equipment to operate according to the control parameters.
[0031] Among them, the control parameters include input voltage, start-stop parameters and running time, etc. The start-stop parameters include start time, running time and stop time. After determining the control parameters, the laundry equipment updates the washing parameters of the laundry equipment in different modes at different stages according to the control parameters. When the laundry equipment starts to run next time, the laundry equipment can work according to the updated washing parameters. When the laundry equipment starts to work, the control system will start the drain pump according to the start time in the start-stop parameters. After the drain pump is started, the drain pump is controlled to work according to the input voltage and the preset running time. During the operation of the drain pump, the drain pump can perform drainage operations according to the washing mode and drainage requirements. When the stop time of the control parameter is reached or the drainage task is completed, the laundry equipment can control the drain pump to stop working. In this solution, during the operation of the laundry equipment, the laundry equipment can also continuously monitor the power grid frequency and the washing status to adjust the control parameters in real time.
[0032] The technical solution of this embodiment is that if the current moment is a preset signal collection moment, the current signal of the power supply of the laundry device is collected within a preset time by the sampling unit, and the current grid frequency corresponding to the power supply at the current moment is determined according to the current signal; the control parameters of the drainage pump of the laundry device are determined based on the current grid frequency and the laundry device information obtained in advance; wherein the control parameters at least include the input voltage; and the laundry device is controlled to operate according to the control parameters. The technical solution of this embodiment can ensure that the laundry device can work normally under different grid conditions by automatically detecting the grid frequency and adjusting the control parameters, and at the same time can optimize the working state of the drainage pump, thereby improving the performance and efficiency of the washing machine. The laundry device can operate in the best state under different grid frequencies and provide better washing effects. Inappropriate grid frequency will cause the motor speed to be unstable, thereby generating additional noise and energy consumption. By adjusting the control parameters to match the current grid frequency, unnecessary noise and energy waste can be reduced, making the laundry device more environmentally friendly while improving the user experience.
[0033] Figure 2This is a second flow chart of a laundry equipment control method provided by an embodiment of the present invention. This embodiment is a refinement based on the above embodiment. The specific method can be as follows Figure 2 As shown, the method may include the following steps:
[0034] Step 201: If the current moment is a preset signal collection moment, a current signal of a power supply of a laundry device is collected within a preset time period by a sampling unit.
[0035] Step 202: Convert the current signal into a pulse signal through a detection circuit, and determine the current grid frequency corresponding to the power supply according to the number of pulse signals within a preset time length.
[0036] Among them, in the AC system, the voltage and current are waveforms that change periodically over time. In order to facilitate processing and analysis, these continuously changing analog signals need to be converted into discrete digital signals. The detection circuit (such as a power supply zero-crossing detection circuit) is used to convert the analog signal into a digital signal. When the AC signal passes through the zero point, that is, the moment when the voltage changes from positive to negative or from negative to positive, the detection circuit generates a pulse signal. The single-chip microcomputer of the laundry device can count the number of pulse signals received within a preset time length. By comparing the number of pulses within the preset time length with the expected number of pulses at the standard frequency, the single-chip microcomputer can calculate the current grid frequency. In the embodiment of this scheme, optionally, the current grid frequency corresponding to the power supply is determined according to the number of pulse signals within the preset time length, including: if the number of pulse signals within the preset time length is greater than or equal to the first preset number and less than or equal to the second preset number, the current grid frequency corresponding to the power supply is determined to be the first frequency; if the number of pulse signals within the preset time length is greater than the second preset number and less than or equal to the third preset number, the current grid frequency corresponding to the power supply is determined to be the second frequency.
[0037] In an optional implementation, the first frequency may be 50 Hz, and the second frequency may be 60 Hz. If the number of pulse signals acquired within the preset duration matches the expected number of pulses corresponding to 50 Hz, the grid frequency is determined to be 50 Hz. Similarly, if the number of pulses matches the expected number of pulses corresponding to 60 Hz, the grid frequency is determined to be 60 Hz. In this solution, the preset duration may be 1 second, the first preset number may be 0, the second preset number may be 55, and the third preset number may be 65.
[0038] In the above steps, the current grid frequency corresponding to the power supply can be accurately determined by the number of pulse signals within a preset time length, thereby improving the accuracy of grid frequency determination.
[0039] Step 203: Based on the predetermined speed-grid frequency relationship and the target speeds, determine the input voltages corresponding to the target speeds at the current grid frequency.
[0040] The laundry equipment information includes each target speed corresponding to each washing mode of each washing stage of the laundry equipment. The speed-grid frequency relationship includes the input voltage corresponding to each speed under different grid frequencies. Specifically, different washing modes in different washing stages correspond to different target speeds. In order for the laundry equipment to achieve each target speed under different grid frequencies, it is necessary to use different input voltages under different grid frequencies. Exemplarily, the washing stage includes stage 1, stage 2 and stage 3, and each stage includes 3 modes, namely mode 1, mode 2 and mode 3. The speed-grid frequency relationship is shown in Table 1 below:
[0041]
[0042] Table 1
[0043] Step 204: Determine the start and stop parameters corresponding to each drainage demand at the current grid frequency according to the predetermined drainage grid frequency relationship and each drainage demand.
[0044] Among them, the laundry equipment information includes the drainage demand corresponding to each washing mode of each washing stage of the laundry equipment, and the control parameters also include the start-stop parameters of the drainage pump, and the start-stop parameters include the start time, the running time and the stop time. The start time is the time point when the drainage pump starts to work. The running time is the length of time the drainage pump continues to work. The larger the drainage volume, the longer the running time. The stop time is the time point when the drainage pump stops working. Reasonable stop time can ensure that all water has been drained while avoiding unnecessary energy waste. Specifically, during the washing process, different washing stages (such as rinsing, washing and drying) and washing modes (such as energy-saving mode, normal mode and strong mode) have different requirements for drainage. For example, the strong mode may require a faster drainage speed and a higher drainage volume, while the energy-saving mode may focus more on water saving and the drainage speed is relatively slow. Each washing stage and washing mode will correspond to a specific drainage demand that can be predetermined based on domain big data and the specification information of the laundry equipment. Due to different grid frequencies (such as 50 Hz or 60 Hz), the working efficiency of the drainage pump will be affected. Therefore, it is necessary to adjust the start and stop parameters according to the current grid frequency to ensure that the drainage pump can work efficiently and stably at different frequencies. For example, at a grid frequency of 60 Hz, the drainage pump may run faster than at a frequency of 50 Hz, so it may be necessary to shorten the running time or stop early.
[0045] Step 205: Generate parameter update prompt information according to the control parameters of the drainage pump of the laundry appliance under the current grid frequency, and display the parameter update prompt information to the user.
[0046] Among them, the parameter update prompt information is used to remind the user that the control parameters of the drainage pump have changed. The parameter update prompt information includes the current grid frequency, the updated control parameter value, the reason for the parameter change, and suggestions for user operations. In an optional embodiment, when the grid frequency changes, the laundry device can automatically calculate and update the control parameters. After completing the calculation of the control parameters, parameter update prompt information can be generated based on the control parameters. After determining the parameter update prompt information, it can be displayed to the user through the user display interface of the laundry device to ensure that the user can understand the changes in the parameters in a timely manner. The laundry device in this solution can also push the parameter update prompt information to the user through a mobile phone application or other smart devices. The user can choose to accept or ignore the parameter update prompt information according to their needs. If the user needs to modify the control parameters, the control parameters can be adjusted through the user interface.
[0047] Step 206: Control the laundry equipment to operate according to the control parameters.
[0048] In the technical solution of this embodiment, if the current moment is a preset signal acquisition moment, the current signal of the power supply of the laundry device is collected within a preset time length by the sampling unit, and the current grid frequency corresponding to the power supply at the current moment is determined according to the current signal. The current signal is converted into a pulse signal by the detection circuit, and the current grid frequency corresponding to the power supply is determined according to the number of pulse signals within the preset time length. Based on the predetermined speed grid frequency relationship and each target speed, each input voltage corresponding to each target speed under the current grid frequency is determined. The laundry device information includes each target speed corresponding to each washing mode of each washing stage of the laundry device. According to the predetermined drainage grid frequency relationship and each drainage demand, the start-stop parameters corresponding to each drainage demand under the current grid frequency are determined. The laundry device information includes the drainage demand corresponding to each washing mode of each washing stage of the laundry device, and the control parameters also include the start-stop parameters of the drainage pump, and the start-stop parameters include the start time, the running time and the stop time. Parameter update prompt information is generated according to the control parameters of the drainage pump of the laundry device under the current grid frequency, and the parameter update prompt information is displayed to the user. The laundry device is controlled to operate according to the control parameters. The technical solution of this embodiment enables the laundry equipment to automatically detect and adapt to the power grid frequency in different regions, ensuring that the laundry equipment can operate normally in various power grid environments. By accurately controlling the input voltage and start-stop parameters of the drainage pump, energy consumption can be adjusted according to actual needs to avoid unnecessary energy waste, which not only helps to reduce operating costs, but also conforms to the trend of energy conservation and emission reduction. The method of this embodiment can reduce unnecessary noise and energy waste by adjusting the control parameters to match the current power grid frequency, making the laundry equipment more environmentally friendly while improving the user experience.
