[0052] See attached Figure 1 , Figure 1 FIG. 1 is a flow chart showing the main steps of a method for weighing laundry items of a washing device according to an embodiment of the present invention. Figure 1 As shown, the method for weighing laundry items of a washing device in the embodiment of the present invention mainly includes the following steps S101 to S104.

[0053] Step S101: when the washing program is started, it is detected whether the water level of the washing device is less than a preset water level threshold.

[0054] In this embodiment, when the washing program is started, it is first detected whether the water level of the washing device is less than a preset water level threshold.

[0055] In one embodiment, the washing device may be a washing machine, a shoe washing machine or the like.

[0056] In one embodiment, the washing program may be a laundry program.

[0057] In one embodiment, the preset water level threshold may be a starting point of the water level of the washing device.

[0058] In one embodiment, the water level of the washing device may be detected by a water level sensor.

[0059] Step S102: when the water level is less than the water level threshold, the washing device is controlled to execute the washing mode, and a first detection value of the weighing circuit in the washing mode is obtained.

[0060] In this embodiment, when the water level is less than the water level threshold, the washing device is controlled to execute the washing mode, and the weighing circuit starts detection. At this time, the value detected by the weighing circuit is the first detection value.

[0061] In one implementation, the first detection value of the weighing circuit may be obtained when laundry items are placed in the washing device but water has not yet been added.

[0062] In one embodiment, the weighing circuit may include a weighing voltage circuit. In the washing mode, the weighing voltage circuit may detect the induced electromotive force of the weighing circuit when the motor of the washing device stops rotating forward or reverse for multiple cycles (such as at least four cycles) to obtain a set of induced electromotive force values. Since the motor rotation cycle in the washing mode is short, the measured induced electromotive force value is large. Therefore, after removing a maximum value and a minimum value from this set of induced electromotive force values, the remaining induced electromotive force values ​​are averaged to obtain a more accurate value, which can be used as the first detection value. The time taken for the motor of the washing device to start rotating forward or reverse for one circle may be one cycle.

[0063] In one embodiment, the weighing circuit may include a weighing voltage circuit. In the washing mode, the weighing voltage circuit may detect the pulse width of the weighing circuit when the motor of the washing device stops rotating forward or reverse for multiple cycles (such as at least four cycles) to obtain a set of pulse widths. Since the motor rotation cycle in the washing mode is short, the measured pulse width fluctuates greatly. Therefore, after removing a maximum value and a minimum value from the set of pulse widths, the remaining pulse widths are averaged to obtain a more accurate value, which can be used as the first detection value.

[0064] In one embodiment, the weighing circuit may include a weighing voltage circuit. In the washing mode, the weighing voltage circuit may detect the number of pulses of the weighing circuit when the motor of the washing device stops rotating forward or reverse for multiple cycles (such as at least four cycles) to obtain a group of pulse numbers. Since the motor rotation cycle in the washing mode is short, the measured pulse number fluctuates greatly. Therefore, after removing a maximum value and a minimum value from the group of pulse numbers, the remaining pulse numbers are averaged to obtain a more accurate value, which can be used as the first detection value.

[0065] In one embodiment, the weighing circuit may include a weighing current circuit. In the washing mode, the weighing current circuit can detect the current value during the forward and reverse rotation of the motor for at least multiple cycles (such as at least four cycles, 10 seconds can be taken as one cycle). Since the current changes during the forward and reverse rotation of the motor, when measuring the current value, an instantaneous current value can be detected every 1 second within a cycle, and a group of instantaneous current values ​​will be obtained after multiple detections. Then, this group of instantaneous current values ​​are averaged to obtain an average value, which is used as the current value of this cycle. After detecting the current values ​​of multiple cycles, the weighing current circuit will obtain a group of current values. Since the current values ​​measured when the motor starts and stops rotating in the washing mode fluctuate greatly, it is necessary to remove a maximum value and a minimum value from this group of current values, and then average the remaining current values ​​to obtain a more accurate value, which can be used as the first detection value.

[0066] Step S103: based on the first detection value, obtaining the first mass of the laundry item.

[0067] In this embodiment, the first detection value is compared with a preset washing mode standard curve to obtain the first mass of the laundry items. The preset washing mode standard curve is a curve reflecting the corresponding relationship between the first detection value and the first mass value.

[0068] In one embodiment, the preset washing mode standard curve can be obtained by those skilled in the art through experiments and statistics. Different types and models of washing equipment can be set with different preset washing mode standard curves.

[0069] In one embodiment, the preset washing mode standard curve may include a preset washing mode induced electromotive force standard curve, a preset washing mode pulse width standard curve, a preset washing mode pulse number standard curve, and a preset washing mode current value standard curve. If the first detection value is a current value, the first detection value is compared with the preset washing mode current value standard curve to obtain the first mass of the washing items. Similarly, if the first detection value is a pulse width, the first detection value is compared with the preset washing mode pulse width standard curve to obtain the first mass of the washing items, and so on.

[0070] Step S104: based on the first mass, obtaining the final mass of the laundry items.

[0071] In this embodiment, the final mass of the laundry items is obtained according to the first mass.

[0072] In one embodiment, the laundry items may be laundry items such as clothes, pants, and shoes.

[0073] Based on the above steps S101 to S104, when the washing program is started, the embodiment of the present invention first detects whether the water level of the washing device is less than the preset water level threshold. When the water level is less than the water level threshold, the washing device is controlled to execute the washing mode, and the first detection value of the weighing circuit in the washing mode is obtained. Based on the first detection value, the first mass of the washing items is obtained, and based on the first mass, the final mass of the washing items is obtained. Through the above configuration, the present invention weighs the washing items once when executing the washing mode to obtain the first mass. The mass of the washing items weighed by the washing device when the washing device is under low load in the washing mode has a high accuracy. Therefore, obtaining the final mass of the washing items based on the first mass can effectively improve the accuracy of the washing items weighed by the washing device when the washing device is under low load.

[0074] The step S103 is further described below.

[0075] In one implementation of the embodiment of the present invention, step S103 may include steps S1031 to S1035:

[0076] Step S1031: Determine whether the first mass is less than a preset clothing mass threshold, if so, execute step S1032, if not, execute step S1033.

[0077] Step S1032: the first mass is taken as the final mass.

[0078] Step S1033: Control the washing machine to execute the dehydration mode, and obtain the second detection value of the weighing circuit in the dehydration mode.

[0079] Step S1034: Obtaining a second mass of the laundry item according to the second detection value.

[0080] Step S1035: Obtain the final quality according to the first quality and the second quality.

[0081] In this embodiment, it is determined whether the first mass is less than a preset clothing mass threshold. In the washing mode, when the mass of the laundry exceeds a value, the weighing accuracy in the washing mode will be significantly reduced, and the clothing mass threshold can be set according to the above value. The clothing mass threshold can be obtained by those skilled in the art through experiments and statistics. Different types and models of washing equipment can set different clothing mass thresholds.

[0082] Since when the first mass is less than the clothing mass threshold, the weighing accuracy of the first mass obtained in the washing mode is high, the first mass can be used as the final mass of the laundry. When the first mass is greater than or equal to the clothing mass threshold, the weighing accuracy of the first mass obtained in the washing mode decreases, and the washing device can be controlled to execute the dehydration mode, and the weighing circuit performs detection in the dehydration mode to obtain a second detection value, and the second mass is obtained according to the second detection value, and then the first mass and the second mass are weighted and calculated to obtain a more accurate value. This more accurate value is used as the final mass of the laundry, which can improve the weighing accuracy of the laundry.

[0083] In one implementation of the embodiment of the present invention, before step S102, steps S105 to S107 may also be included:

[0084] Step S105: controlling the washing machine to execute the dehydration mode, and obtaining the second detection value of the weighing circuit in the dehydration mode.

[0085] Step S106: based on the second detection value, obtaining the second mass of the laundry items.

[0086] Step S107: Perform weighted calculation on the first quality and the second quality to obtain a final quality.

[0087] In this embodiment, before the washing device executes the washing mode, the washing device can first execute the dehydration mode. In the dehydration mode, the weighing circuit starts detection. The value detected by the weighing circuit is the second detection value. The second detection value is compared with the preset dehydration mode standard curve to obtain the second mass. The first mass and the second mass are weightedly calculated to obtain the final mass of the washed items.

[0088] Since there is a large error in the mass of the laundry items measured in the dehydration mode or the washing mode, the first mass measured in the washing mode and the second mass measured in the dehydration mode are weighted and calculated to obtain a more accurate mass as the final mass of the laundry items. The preset dehydration mode standard curve is a curve reflecting the corresponding relationship between the second detection value and the second mass value.

[0089] In one embodiment, the preset dehydration mode standard curve can be obtained by those skilled in the art through experiments and statistics. Different types and models of washing equipment can be set with different preset dehydration mode standard curves.

[0090] In one embodiment, in the dehydration mode, the weighing circuit detects the induced electromotive force or pulse width or pulse number of the weighing circuit when the motor of the washing machine stops rotating forward or reverse for at least one cycle. The values ​​detected by the weighing circuit are averaged and the calculated value is the second detection value. The time taken for the motor of the washing machine to start rotating forward or reverse for one circle can be one cycle.

[0091] In one embodiment, in the dehydration mode, the weighing circuit detects the current value during at least one cycle of the motor's forward and reverse rotation. The values ​​detected by the weighing circuit are averaged, and the calculated value is the second detection value. One cycle can be 10 seconds.

[0092] In one embodiment, the preset dehydration mode standard curve may include a preset dehydration mode induced electromotive force standard curve, a preset dehydration mode pulse width standard curve, a preset dehydration mode pulse number standard curve, and a preset dehydration mode current value standard curve. If the second detection value is a current value, the second detection value is compared with the preset dehydration mode current value standard curve to obtain the second mass of the washing items. Similarly, if the second detection value is a pulse width, the second detection value is compared with the preset dehydration mode pulse width standard curve to obtain the second mass of the washing items, and so on.

[0093] In one implementation of the embodiment of the present invention, step S103 may further include steps S108 to S110:

[0094] Step S108: controlling the washing machine to execute the dehydration mode, and obtaining the second detection value of the weighing circuit in the dehydration mode.

[0095] Step S109: based on the second detection value, obtaining the second mass of the laundry items.

[0096] Step S110: performing weighted calculation on the first quality and the second quality to obtain a final quality.

[0097] In this embodiment, the washing device is controlled to execute the dehydration mode. In the dehydration mode, the weighing circuit starts detection. The value detected by the weighing circuit is the second detection value. The second detection value is compared with a preset dehydration mode standard curve to obtain a second mass. The first mass and the second mass are weightedly calculated to obtain the final mass of the washed items.

[0098] It should be pointed out that although the various steps in the above embodiments are described in a specific order, those skilled in the art can understand that in order to achieve the effects of the present invention, different steps do not have to be performed in such an order. They can be performed simultaneously (in parallel) or in other orders. These changes are within the scope of protection of the present invention.
