Description

Technical Field

[0001] This application belongs to the technical field of washing equipment, and particularly relates to a calibration method and device for a flowmeter, a washing equipment, and a computer-readable storage medium. Background Art

[0002] A flowmeter is usually used to measure the water inflow in the water inlet pipe of a washing equipment (such as a dishwasher or a baby bottle sterilizer). During the use of the above-mentioned washing equipment, foreign objects may adhere to the impeller of the flowmeter, resulting in abnormal rotation speed, or the water inlet pipe may be partially blocked by foreign objects, so that the water inflow corresponding to the number of pulses of the flowmeter is inaccurate, leading to abnormal water inlet. Therefore, it is necessary to calibrate the flowmeter.

[0060] Please refer to Figure 1 , Figure 1 which is a flowchart of the implementation of a calibration method for a flowmeter provided by an embodiment of the present application. In the embodiment of the present application, the execution subject of the calibration method for the flowmeter is a washing device. Among them, the washing device can be a dishwasher.

[0061] As Figure 1 shown, the calibration method for the flowmeter provided by an embodiment of the present application may include S101 to S103, which are described in detail as follows:

[0062] In S101, water inlet operation is performed on the inner tank of the washing device based on a preset water inlet volume; a flow meter is arranged on the water inlet pipeline of the inner tank.

[0063] In practical applications, in order to determine the water inlet volume of the inner tank of the washing device, a flow meter is usually arranged on the water inlet pipeline of the inner tank of the washing device.

[0064] In the embodiment of the present application, before the user wants to use the washing device, a first preset operation for the flow meter in the washing device can be triggered first. Among them, the first preset operation can be determined according to actual needs and is not limited here. Exemplarily, the first preset operation can be clicking a first preset control. That is, if the washing device detects that the user clicks the first preset control on the washing device, it is considered that the first preset operation for the washing device is detected; of course, the first preset operation can also be a time-triggered operation. The washing device can be configured with a corresponding washing process during operation, and the washing process includes trigger nodes for multiple key events. The above key events include calibration events for the flow meter. In this case, if the washing device detects that it reaches the trigger node associated with the calibration event of the flow meter, the operations of S101 to S103 are executed to perform the calibration operation on the flow meter of the washing device.

[0065] After the washing device detects the above first preset operation, it can perform a water inlet operation on the inner tank of the washing device based on a preset water inlet volume. Among them, the preset water inlet volume can be set according to actual needs and is not limited here.

[0066] In an implementation manner of the embodiment of the present application, since the water inlet volume affects the water inlet duration, in order to shorten the water inlet time and improve the calibration efficiency, the preset water inlet volume can be set to 1 liter.

[0067] In the embodiment of the present application, when the washing device performs the above water inlet operation, it also needs to detect in real time whether the water with the preset water inlet volume has been completely inlet.

[0068] In some possible embodiments, when the washing device intakes water into the inner tank of the washing device through a water pipe, in order to determine that the water inlet volume in the inner tank of the washing device is the preset water inlet volume, a water level detection device can be arranged in the inner tank of the washing device. Therefore, the washing device can detect whether the water volume in the inner tank of the washing device reaches the preset water inlet volume through this water level detection device.

[0069] In S102, if it is detected that the water with the preset water inlet volume has been completely inlet, the actual pulse number collected by the flow meter from the start time of water inlet to the end time of water inlet is obtained.

[0070] In the embodiment of the present application, when the washing device detects that the water with the preset water inlet volume has finished entering, it indicates that the washing device can start calibrating the flow meter. Therefore, the washing device can obtain the actual number of pulses collected by the flow meter in real time from the moment when the water inlet starts to the moment when the water inlet is completed.

[0071] Among them, the moment when the water inlet starts refers to the moment when the washing device performs the water inlet operation on the inner tank of the washing device. The moment when the water inlet is completed refers to the moment when the water volume in the inner tank of the washing device reaches the preset water inlet volume, that is, the moment when the water with the preset water inlet volume has finished entering.

[0072] In S103, according to the preset water inlet volume and the actual number of pulses, determine the target pulse reference value of the flow meter.

[0073] In the embodiment of the present application, after the washing device obtains the actual number of pulses collected by the flow meter, it can calculate the target pulse reference value of the flow meter according to the preset water inlet volume and the actual number of pulses, so that the washing device can supply water to the inner tank of the washing device based on the target pulse reference value in the subsequent washing process.

[0074] In an embodiment of the present application, the washing device can calculate the target pulse reference value according to the following formula:

[0075]

[0076] Among them, p s represents the target pulse reference value, P1 represents the actual number of pulses, and M1 represents the preset water inlet volume.

[0077] In the embodiment of the present application, after the washing device obtains the target pulse reference value of the flow meter, it can store the target pulse reference value in the memory of the washing device, so as to facilitate the subsequent washing device to supply water to the inner tank of the washing device according to the target pulse reference value.

[0078] As can be seen from the above, a calibration method for a flow meter provided by an embodiment of the present application performs a water inlet operation on the inner tank of the washing device based on a preset water inflow. Since a flow meter is configured on the water inlet path of the inner tank, when it is detected that the water with the preset water inflow has finished entering, the actual pulse count collected by the flow meter from the start time of water inlet to the end time of water inlet can be obtained. Finally, the target pulse reference value of the flow meter can be directly determined according to the above preset water inflow and the above actual pulse count. The calibration method for the flow meter provided by the embodiment of the present application does not require installing another flow meter as a reference flow meter in the washing device. After the inner tank has completed the water inlet of the preset water inflow, the actual pulse count collected by the flow meter can be obtained in real time, and then the target pulse reference value of the flow meter can be determined, thereby completing the calibration of the flow meter. The operation is simple, the calibration efficiency of the flow meter is improved, and the situation of too much or too little water inflow in the inner tank during the subsequent water inlet of the washing device is avoided.

[0079] In an embodiment of the present application, when the washing device intakes water into the inner tank of the washing device through a water tank, in order to ensure that the water inflow in the inner tank of the washing device is the preset water inflow and improve the calibration accuracy of the flow meter, a water level detection device may be configured in the water tank communicated with the water inlet path of the inner tank of the washing device to detect the water volume in the water tank. Based on this, please refer to Figure 2 , Figure 2 which is a flowchart of the implementation of the calibration method for the flow meter provided by another embodiment of the present application. Compared with the Figure 1 corresponding embodiment, the calibration method for the flow meter provided by this embodiment may further include S201 before S101. Correspondingly, S202 may be included after S101. Correspondingly, S103 may include S203, which are described in detail as follows:

[0080] In S201, read the first signal value fed back by the water level detection device located inside the water tank to determine the initial water volume of the water tank.

[0081] In this embodiment, when the washing device performs a water inlet operation on the inner tank of the washing device, it may first read the first signal value fed back by the water level detection device located inside the water tank and determine the initial water volume of the water tank, that is, the water volume before starting to intake water into the inner tank of the washing device.

[0082] In S202, read the second signal value fed back by the water level detection device located inside the water tank at a preset acquisition period to determine the current water volume of the water tank.

[0083] In practical applications, the water inflow volume in the inner tank of the washing device is the same as the reduced water volume in the water tank. Therefore, in order to detect in real time that the water inflow volume in the inner tank of the washing device is the preset water inflow volume, after performing the water inlet operation on the inner tank of the washing device, the washing device can read the second signal value feedback by the water level detection device located in the inner tank of the water tank at a preset acquisition period, and determine the current water volume of the water tank at this time according to the second signal value.

[0084] Among them, the preset acquisition period can be set according to actual needs and is not limited here. Exemplarily, since the greater the water inlet rate, the shorter the time for the water inflow volume in the inner tank of the washing device to reach the preset water inflow volume, in order to accurately detect the moment when the water inflow volume in the inner tank reaches the preset water inflow volume, the preset acquisition period can be determined according to the water inlet rate, that is, the greater the water inlet rate, the shorter the preset acquisition period.

[0085] In this embodiment, after the washing device determines the current water volume of the water tank, it can calculate the water volume difference between the initial water volume and the current water volume of the water tank, and compare the water volume difference with the preset water inflow volume.

[0086] In an embodiment of the present application, when the washing device detects that the above water volume difference is equal to the preset water inflow volume, it can execute step S203.

[0087] In another embodiment of the present application, when the washing device detects that the above water volume difference is less than the preset water inflow volume, it means that the water inflow volume in the inner tank of the washing device has not reached the preset water inflow volume. Therefore, the washing device can continue to execute step S202 until the water volume difference between the initial water volume and the current water volume of the water tank is equal to the preset water inflow volume.

[0088] In still another embodiment of the present application, when the washing device detects that the above water volume difference is greater than the preset water inflow volume, it means that the water inflow volume in the inner tank of the washing device has exceeded the preset water inflow volume. In order to improve the calibration accuracy of the flow meter, the washing device needs to drain the water in the inner tank of the washing device and re - execute steps S201 - S202.

[0089] In S203, if it is detected that the water volume difference between the initial water volume and the current water volume is equal to the preset water inflow volume, then obtain the actual number of pulses collected by the flow meter from the start time of the water inlet to the end time of the water inlet.

[0090] In this embodiment, when the washing device detects that the above water volume difference is equal to the preset water inflow volume, it means that the water inflow volume in the inner tank of the washing device just reaches the preset water inflow volume. At this time, the washing device can obtain the actual number of pulses collected by the flow meter from the start time of the water inlet to the end time of the water inlet.

[0091] As can be seen from the above, for a calibration method of a flow meter provided in this embodiment, before performing a water inlet operation on the inner tank of the washing device, the first signal value fed back by the water level detection device located inside the water tank can be read first to determine the initial water volume of the water tank. After the above water inlet operation, the second signal value fed back by the water level detection device located inside the water tank can be read at a preset acquisition period to determine the current water volume of the water tank, and whether the water inlet volume is a preset water inlet volume can be determined according to the initial water volume and the current water volume. When it is detected that the water volume difference between the initial water volume and the current water volume is equal to the preset water inlet volume, it can be determined that the water inlet is completed. Therefore, the actual number of pulses collected by the flow meter from the start time of water inlet to the end time of water inlet can be obtained, ensuring that the actual number of pulses collected by the flow meter is indeed the number of pulses under the preset water inlet volume, and improving the calibration accuracy of the flow meter.

[0092] In another embodiment of the present application, in order to improve the calibration accuracy of the calibration method of the flow meter in S101-S103 above, before calibrating the flow meter of the washing device, the flow meter can be pre-calibrated first. Based on this, please refer to Figure 3 , Figure 3 is the implementation flowchart of the calibration method of the flow meter provided in another embodiment of the present application. Compared with Figure 1 the corresponding embodiment, for the calibration method of the flow meter provided in this embodiment, step S101 can specifically include S301-S303, which are described in detail as follows:

[0093] In S301, based on the preset water inlet volume, perform a preset number of pre-water inlet operations on the inner tank.

[0094] In this embodiment, before the user wants to calibrate the flow meter in the washing device, a second preset operation for the flow meter in the washing device can be triggered first. Among them, the second preset operation can be determined according to actual needs and is not limited here. Exemplarily, the second preset operation can be clicking a second preset control. That is, if the washing device detects that the user clicks the second preset control on the washing device, it is considered that the second preset operation for the washing device is detected; of course, the second preset operation can also be a time-triggered operation. The washing device can be configured with a corresponding washing process during operation, and the washing process includes trigger nodes for multiple key events. The above key events include the pre-calibration event of the flow meter. In this case, if the washing device detects that it reaches the trigger node associated with the pre-calibration event of the flow meter, the operations of S301-S303 are executed to perform the pre-calibration operation on the flow meter of the washing device.

[0095] After detecting the above-mentioned second preset operation, the washing device may perform a preset number of pre-water inlet operations on the inner tank of the washing device based on a preset water inlet volume. The preset number can be set according to actual needs and is not limited here. Exemplarily, in order to ensure the accuracy rate of the pre-calibration of the flow meter and the efficiency of the pre-calibration, the preset number can be set to 4 times.

[0096] In S302, for each pre-water inlet operation, when it is detected that the water of the preset water inlet volume has finished inletting, obtain the calibration pulse number collected by the flow meter under the pre-water inlet operation.

[0097] In this embodiment, for each pre-water inlet operation, when the washing device detects that the water of the preset water inlet volume in the inner tank of the washing device has finished inletting during this pre-water inlet operation, it indicates that the washing device can start pre-calibrating the flow meter under this pre-water inlet operation. Therefore, the washing device can obtain the calibration pulse number collected by the flow meter under this pre-water inlet operation, that is, the washing device can obtain the calibration pulse number that the flow meter has collected in real time from the start moment of the pre-water inlet to the end moment of the pre-water inlet under this pre-water inlet operation.

[0098] Among them, the start moment of the pre-water inlet refers to the moment when the washing device performs this pre-water inlet operation on the inner tank of the washing device during a certain pre-water inlet operation. The end moment of the pre-water inlet refers to the moment when the water inlet volume in the inner tank of the washing device reaches the preset water inlet volume during this pre-water inlet operation, that is, the moment when the water of the preset water inlet volume has finished inletting during this pre-water inlet operation.

[0099] In this embodiment, the washing device can obtain a corresponding calibration pulse number for each pre-water inlet operation. That is to say, after the washing device finishes performing the preset number of pre-water inlet operations, it can obtain a plurality of calibration pulse numbers corresponding to the preset number.

[0100] Based on this, the washing device can detect whether the above-mentioned plurality of calibration pulse numbers meet the preset water inlet trigger condition. The preset water inlet trigger condition can be set according to actual needs and is not limited here.

[0101] In an embodiment of the present application, when the washing device detects that the above-mentioned plurality of calibration pulse numbers meet the preset water inlet trigger condition, it can perform step S303.

[0102] In another embodiment of the present application, when the washing device detects that the above-mentioned plurality of calibration pulse numbers do not meet the preset water inlet trigger condition, it indicates that the pre-calibration of the flow meter fails, that is, the calibration accuracy of the flow meter is inaccurate. Therefore, the washing device needs to re-execute steps S301 to S302 until the plurality of calibration pulse numbers obtained by the washing device meet the preset water inlet trigger condition.

[0103] In S303, if it is detected that a plurality of the calibration pulse counts corresponding to the preset number of times meet a preset water inlet trigger condition, a water inlet operation is performed on the inner tank based on the preset water inlet volume.

[0104] In this embodiment, when the washing device detects that a plurality of calibration pulse counts corresponding to the preset number of times meet the preset water inlet trigger condition, it indicates that the pre-calibration of the flowmeter is successful, that is, the calibration accuracy of the flowmeter is accurate. Therefore, the washing device can perform a calibration operation on the flowmeter, that is, perform a water inlet operation on the inner tank of the washing device based on the preset water inlet volume.

[0105] In an embodiment of the present application, the washing device can specifically determine that a plurality of calibration pulse counts corresponding to the preset number of times meet the preset water inlet trigger condition through steps S401 to S402 as shown in Figure 4 and perform a water inlet operation on the inner tank of the washing device based on the preset water inlet volume, which is described in detail as follows:

[0106] In S401, a plurality of the calibration pulse counts corresponding to the preset number of times are divided into a first pulse set and a second pulse set.

[0107] In this embodiment, the washing device can divide a plurality of calibration pulse counts corresponding to the preset number of times into a first pulse set and a second pulse set according to preset requirements.

[0108] In an embodiment of the present application, the preset requirements may be: according to the purity of the water in the inner tank of the washing device during each pre-water inlet operation, the calibration pulse counts collected during the pre-water inlet operation are divided.

[0109] Specifically, the washing device can divide a plurality of calibration pulse counts corresponding to the preset number of times through steps S501 to S503 as shown in Figure 5 and the details are as follows:

[0110] In S501, for each pre-water inlet operation, the actual water purity of the water is determined by a water quality detection device, and the actual water purity is associated and stored with the calibration pulse counts collected by the flowmeter during the pre-water inlet operation.

[0111] In S502, if it is detected that the purity difference between the actual water purity and the standard purity is less than or equal to a second preset threshold, the calibration pulse counts corresponding to the actual water purity are divided into the first pulse set.

[0112] In S503, if it is detected that the purity difference between the actual water purity and the standard purity is greater than the second preset threshold, the calibration pulse counts corresponding to the actual water purity are divided into the second pulse set.

[0113] In this embodiment, since there may be other impurities or foreign objects in the water, and these impurities or foreign objects will adhere to the impeller of the flow meter, resulting in abnormal rotation speed, or these impurities or foreign objects will block part of the water inlet pipe, so that the number of calibration pulses collected by the flow meter in each pre-water inlet operation is different. Therefore, a water quality detection device can be configured inside the inner tank of the washing device. For each pre-water inlet operation, the washing device can detect the actual water purity of the water in the inner tank of the washing device through the above-mentioned water quality detection device during this pre-water inlet operation, and associate and store the actual water purity with the number of calibration pulses collected during this pre-water inlet operation.

[0114] It should be noted that the standard purity of water is stored in the memory of the washing device. Among them, the standard purity can be determined according to actual needs and is not limited here. Exemplarily, the standard purity can be determined according to the average value of the historical purities of the water corresponding to all historical water inlet times performed by the washing device within a historical time period. Among them, the historical time period can be set according to actual needs and is not limited here.

[0115] Based on this, for each pre-water inlet operation, the washing device can calculate the purity difference between the actual water purity and the standard purity during this pre-water inlet operation, and compare the purity difference with a second preset threshold. Among them, the second preset threshold can be set according to actual needs and is not limited here.

[0116] In this embodiment, when the washing device detects that the purity difference between the actual water purity and the standard purity during a certain pre-water inlet operation is less than or equal to the second preset threshold, it can divide the number of calibration pulses corresponding to the actual purity into a first pulse set.

[0117] When the washing device detects that the purity difference between the actual water purity and the standard purity during a certain pre-water inlet operation is greater than the second preset threshold, it can divide the number of calibration pulses corresponding to the actual purity into a second pulse set.

[0118] In another embodiment of the present application, the preset requirement can be: according to the water inlet time of the preset water inlet volume in the inner tank of the washing device during each pre-water inlet operation, that is, the water inlet duration for performing this pre-water inlet operation, divide the number of calibration pulses collected during this pre-water inlet operation.

[0119] Specifically, the washing device can divide a plurality of calibration pulses corresponding to the preset number through steps S601 to S603 as shown in Figure 6 as follows:

[0120] In S601, for each pre-inlet water operation, according to the pre-inlet water start time and the pre-inlet water completion time corresponding to the pre-inlet water operation, determine the inlet water duration corresponding to the pre-inlet water operation.

[0121] In S602, if it is detected that the time difference between the inlet water duration and the standard duration is less than or equal to the third preset threshold, divide the number of verification pulses collected during the pre-inlet water operation into the first pulse set.

[0122] In S603, if it is detected that the purity difference between the inlet water duration and the standard duration is greater than the third preset threshold, divide the number of verification pulses collected during the pre-inlet water operation into the second pulse set.

[0123] In this embodiment, since the longer the inlet water duration for the preset water inlet volume, the smaller the number of verification pulses collected by the flow meter. Therefore, for each pre-inlet water operation, the washing device can determine the inlet water duration corresponding to the pre-inlet water operation according to the pre-inlet water start time and the pre-inlet water completion time corresponding to the pre-inlet water operation.

[0124] It should be noted that the standard duration of the preset water inlet volume is stored in the memory of the washing device. Among them, the standard duration can be determined according to actual needs and is not limited here. Exemplarily, the standard duration can be determined according to the average value of the historical inlet water durations corresponding to all preset water inlet volumes of the washing device within the historical time period.

[0125] Based on this, for each pre-inlet water operation, the washing device can calculate the time difference between the inlet water duration under the pre-inlet water operation and the standard duration, and compare the time difference with the third preset threshold. Among them, the third preset threshold can be set according to actual needs and is not limited here.

[0126] In this embodiment, when the washing device detects that the time difference between the inlet water duration and the standard duration under a certain pre-inlet water operation is less than or equal to the third preset threshold, it can divide the number of verification pulses collected during the pre-inlet water operation into the first pulse set.

[0127] When the washing device detects that the time difference between the inlet water duration and the standard duration under a certain pre-inlet water operation is greater than the third preset threshold, it can divide the number of verification pulses collected during the pre-inlet water operation into the second pulse set.

[0128] In this embodiment, after the washing device divides the multiple verification pulses corresponding to the preset number into the first pulse set and the second pulse set, it can calculate the pulse average value of the first pulse set to obtain the first pulse average value, and calculate the pulse average value of the second pulse set to obtain the second pulse average value.

[0129] After that, the washing device can calculate the mean difference between the above-mentioned first pulse average value and the second pulse average value, and compare the mean difference with a first preset threshold value. The first preset threshold value can be set according to actual needs and is not limited here.

[0130] In an embodiment of the present application, when the washing device detects that the mean difference is less than the first preset threshold value, it executes step S402.

[0131] In another embodiment of the present application, when the washing device detects that the mean difference is greater than or equal to the first preset threshold value, it indicates that the difference between the first pulse average value and the second pulse average value is relatively large. That is to say, the number of verification pulses in the first pulse set is quite different from the number of verification pulses in the second pulse set. In other words, the pre-calibration of the flow meter fails, that is, the calibration accuracy of the flow meter is inaccurate. Therefore, the washing device needs to continue to execute steps S301 to S303 until the mean difference is less than the first preset threshold value.

[0132] In S402, if it is detected that the mean difference between the first pulse average value and the second pulse average value is less than the first preset threshold value, a water inlet operation is performed on the inner tank based on the preset water inlet volume; the first pulse average value is obtained from the first pulse set, and the second pulse average value is obtained from the second pulse set.

[0133] In this embodiment, when the washing device detects that the mean difference between the first pulse average value and the second pulse average value is less than the first preset threshold value, it indicates that the difference between the first pulse average value and the second pulse average value is relatively small and can be ignored. That is to say, the number of verification pulses in the first pulse set is quite similar to the number of verification pulses in the second pulse set. In other words, the pre-calibration of the flow meter is successful, that is, the calibration accuracy of the flow meter is accurate. Therefore, the washing device can execute steps S101 to S103.

[0134] As can be seen from the above, a calibration method for a flow meter provided in this embodiment can first perform a preset number of pre-water inlet operations on the inner tank based on a preset water inlet volume before calibrating the flow meter in the washing device; for each pre-water inlet operation, when it is detected that the water of the preset water inlet volume has finished entering, obtain the number of verification pulses collected by the flow meter under this pre-water inlet operation; and when it is detected that a plurality of the above-mentioned verification pulses corresponding to the preset number meet the preset water inlet trigger condition, it indicates that the calibration accuracy of the flow meter is accurate. At this time, a water inlet operation can be performed on the inner tank based on the preset water inlet volume, thereby improving the calibration accuracy rate and success rate of the flow meter.

[0135] Please refer to Figure 7 , Figure 7 which is a flowchart for implementing the calibration method of the flow meter provided in another embodiment of the present application. Relative toFigure 1 For the corresponding embodiment, the calibration method of the flowmeter provided in this embodiment may further include S701 to S704 after S103, which are described in detail as follows:

[0136] In S701, in response to the water inlet instruction, obtain the target water inlet volume of the washing device.

[0137] In this embodiment, the washing device receiving the water inlet instruction may be: detecting that the user triggers a third preset operation for the washing device. Among them, the third preset operation can be determined according to actual needs and is not limited here. Exemplarily, the third preset operation may be clicking a third preset control. That is, if the washing device detects that the user clicks the third preset control on the washing device, it is considered that the third preset operation for the washing device is detected; of course, this preset operation can also be a time-triggered operation. The washing device can be configured with a corresponding washing process during operation, and this washing process includes trigger nodes for multiple key events. The above key events include the event of filling water into the inner tank of the washing device. In this case, if the washing device detects that it reaches the trigger node associated with the event of filling water into the inner tank of the washing device, it will execute the operations of S701 to S704 to perform the water inlet operation for the inner tank of the washing device.

[0138] Based on this, the washing device can obtain the target water inlet volume of the washing device in response to the water inlet instruction.

[0139] In S702, according to the target water inlet volume and the target pulse reference value, determine the target water inlet pulse number corresponding to the target water inlet volume.

[0140] In this embodiment, after the washing device obtains the target water inlet volume, it can also obtain the target pulse reference value after the flowmeter is calibrated from its own memory, and calculate the target water inlet pulse number corresponding to the target water inlet volume according to the target water inlet volume and the target pulse reference value.

[0141] In an embodiment of the present application, the washing device can calculate the target water inlet pulse number according to the following formula:

[0142] P2 = p s *M2;

[0143] Wherein, P2 represents the target water inlet pulse number, p s represents the target pulse reference value, and M2 represents the target water inlet volume.

[0144] In S703, start counting through the flowmeter when starting to fill water into the inner tank.

[0145] In S704, stop filling water into the inner tank when the flowmeter reaches the target water inlet pulse number.

[0146] In this embodiment, after the washing device obtains the target water inlet pulse number, it can start to supply water to the inner tank of the washing device, and after starting to supply water, the water inlet pulse number is recorded in real time through a flow meter.

[0147] When the washing device detects that the water inlet pulse number of the flow meter reaches the target water inlet pulse number, it indicates that the water inflow volume in the inner tank of the washing device reaches the target water inflow volume. Therefore, the washing device can stop supplying water to the inner tank of the washing device at this time.

[0148] As can be seen from the above, in a flow meter calibration method provided in this embodiment, after completing the calibration of the flow meter, that is, after obtaining the target pulse reference value of the flow meter, in response to a water inlet instruction, the target water inflow volume of the washing device can be obtained; according to the target water inflow volume and the target pulse reference value, the target water inlet pulse number corresponding to the target water inflow volume is determined, and then, when starting to supply water to the inner tank, counting is performed through the flow meter; and when the flow meter reaches the target water inlet pulse number, the water supply to the inner tank is stopped, so as to ensure that the water inflow volume in the inner tank of the washing device is equal to the target water inflow volume, neither too much nor too little, improving the water inlet accuracy.

[0149] It should be understood that the magnitudes of the sequence numbers of the steps in the above embodiments do not mean the order of execution, and the execution order of each process should be determined according to its function and internal logic, and should not constitute any limitation to the implementation process of the embodiments of the present application.
