[0048] A first aspect of an embodiment of the present invention discloses a weighing method for a clothes processing device, such as Figure 1 As shown, the method includes S1 to S3, wherein:

[0049] S1, when it is necessary to weigh the clothes in the clothes processing barrel, detecting whether there is water in the clothes processing barrel;

[0050] S2, when water is detected in the barrel, first determine the moisture content of the clothes, then control the clothes treatment barrel to drain water, and after the drainage is completed, weigh the clothes in the barrel using a weighing circuit;

[0051] S3, determining the actual weight of the clothes according to the moisture content of the clothes and the weight measured by the weighing circuit.

[0052] The weighing method provided by the embodiment of the present invention first detects whether there is water in the barrel before weighing. If there is water, the weighing method of water in the barrel is executed, that is, the moisture content of the clothes is first determined, and then the clothes processing barrel is controlled to drain water. After the drainage is completed, the existing weighing circuit is used to weigh the clothes in the barrel, which can make the weighing result more accurate and avoid the problem of inaccurate weighing value caused by weighing when there is water in the barrel; when there is no water in the barrel, the existing weighing circuit is directly used to weigh the clothes in the barrel, which effectively reduces the weighing time, improves the clothing washing efficiency, and enhances the user experience. This weighing method is simple, convenient and low-cost.

[0053] Clothes processing equipment includes washing machines, washer-dryers, etc.

[0054] In an implementation of the embodiment of the present invention, the clothing processing device further includes a motor, and the weighing circuit is connected to the motor. The weighing circuit is used to weigh the clothing in the barrel in S2, including S21 to S22, wherein:

[0055] S21, controlling the motor to run for a preset time at a set beat, where the set beat includes at least one of the motor's rotation speed, run-to-stop ratio, and acceleration;

[0056] S22, the neutral line and the live line of the control motor are disconnected, the rotation information of the motor after power failure is obtained by using the weighing circuit, and the weight of the articles in the barrel is determined according to the rotation information.

[0057] Different motor operation rhythms are obtained by controlling any one or more of the motor's speed, the ratio of rotation to stop, and the acceleration. When the weighing circuit is used for weighing, after the motor is controlled to run at a set rhythm (preferably the motor is controlled to run at a set speed) for a preset time, the neutral line and the live line of the motor are disconnected at the same time. According to the existing weighing circuit, the motor is an inductive load, and the PWM wave output by this weighing circuit is used to weigh the clothes after the motor is powered off. On the one hand, for clothes under the same control conditions, when the speed is high before the motor is powered off, the total duration of the high level will be longer. Therefore, when the clothes processing equipment is powered on for weighing, the motor works according to the prescribed rhythm before the power is off, which can improve the stability and accuracy of weighing; on the other hand, the neutral line and the live line of the motor are both disconnected to achieve the purpose of double protection, avoiding the existence of other circuits when only the live line is disconnected, causing the motor to output normally, resulting in inaccurate weighing.

[0058] The above rotation information includes any one or more of the number of pulses, the number of zero crossings and the total duration of the high level after the motor is powered off.

[0059] In an implementation of the embodiment of the present invention, S22 uses a weighing circuit to obtain rotation information of the motor after power failure, and determines the weight of the clothes in the barrel according to the rotation information, including S221 to S223.

[0060] in:

[0061] S221, using the weighing circuit to obtain the PWM wave output after the motor is powered off;

[0062] S222, counting the total duration of the high level of the PWM wave;

[0063] S223, determining the weight of the clothes in the barrel according to the total duration of the high level.

[0064] Figure 3 The weighing circuit provided by the embodiment of the present invention is combined with Figure 3, the connection point between the motor and the weighing circuit, one end is connected to the forward end of the motor, and the other end is connected to the reverse end of the motor; the resistance parameters are selected according to the current usage; the diode model is selected according to the actual withstand voltage; the specific parameters of the capacitor are selected according to the actual filtering usage; specifically, the diode D1 and the transistors U1 and U2 are selected according to the rated power and rated voltage of the motor, and then the resistors are selected according to the reverse withstand voltage value of the diode D1 and the rated current of the transistor; the resistor R1 connected in parallel with the diode D1 plays a shunt role to prevent the diode D1 from being damaged by excessive current, and the remaining resistors (R2~R6) all play a current limiting role to prevent excessive current from damaging other components. In addition, the transistors U1 and U2 can be replaced by optocouplers; in this embodiment, the transistors U1 and U2 are both NPN type. The principle of this weighing circuit is: the weighing circuit is connected to both ends of the motor. When the motor is working, a series of PWM waves are output at the output end by using the function of two transistors, and the output end is connected to the chip port. The chip is used to process this PWM wave to obtain the total duration of the high level of the PWM wave, and the weight of the clothes is obtained according to the total duration of the high level of the PWM wave. The embodiment of the present invention uses a weighing method that counts the total duration of the high level after the zero and live wires of the motor are disconnected, so that the weighing result is more accurate.

[0065] Among them, the high and low levels can be judged by setting a voltage threshold. When the detection voltage is greater than or equal to the set voltage threshold, it is regarded as a high level. Conversely, when the detection voltage is less than the set voltage threshold, it is regarded as a low level.

[0066] In an implementation of the embodiment of the present invention, the laundry processing device further includes a zero-live line control circuit connected to the motor, and controlling the zero line and the live line of the motor to be disconnected includes:

[0067] By sending a preset control signal to the zero-live line control circuit, the zero-live line control circuit is used to control the zero line and the live line of the motor to be disconnected in response to the preset control signal.

[0068] Figure 4 The zero-live line control circuit provided by the embodiment of the present invention. Figure 4 As shown, the zero-live line control circuit includes a relay, a needle holder and a diode; the relay includes a power port, a chip signal receiving terminal and a motor terminal, and the power port is used to connect the power supply (12V) to the relay; the needle holder includes two ports, one of which is connected to the relay and the other is connected to the motor; 5V is the power supply for other loads. When the relay is closed, 5V and the live wire share a line. When the relay is closed, the 5V in this line is still 5V to the ground, but 5V to the zero line is 220V. When the relay is not closed, 5V and the zero line are separated; the role of the diode is to clamp the voltage at 12V to prevent excessive voltage from damaging the relay.

[0069] Specifically, combined Figure 2 When the user selects a mode and puts clothes into the washing machine, the washing machine first detects whether there is water in the barrel. If the water level sensor detects that there is water in the barrel, the weighing method of the water in the barrel is executed, that is, the water level sensor is used to detect the amount of water in the barrel, and the water content K of the corresponding amount of water is obtained (the water content K of the clothes is obtained from a large number of experiments in the early stage), and then the water is drained and weighed, and then the actual weight M=mm×K is calculated by the weighed weight m and the water content K. If it is detected that there is no water in the barrel, the laundry is weighed directly, that is, on the basis of the existing weighing circuit, the main chip controls the zero and live wires of the motor to be disconnected, and the weighing circuit is used to detect the total high-level duration of the PWM wave after the motor disconnects the zero and live wires, and the weight of the clothes is obtained according to the total high-level duration of the PWM wave. In this way, the water intake is reasonably controlled, the weighing time is effectively reduced, the washing efficiency of clothes is improved, and the user experience is improved. This weighing method is simple, convenient and low-cost.

[0070] When the washing machine is powered on, the two ends of the motor are connected to the neutral and live wires. When weighing is required, the main chip gives Figure 4 The chip signal receiving end of the zero-live wire control circuit sends a high level. At this time, the relay is disconnected, and the zero-live wire of the motor is successfully cut off. At this time, since the motor is an inductive load, the motor will still output PWM waves. Figure 3 The output end of the weighing circuit will still output PWM waves, so the clothes can be weighed based on this. After the motor is disconnected from the neutral and live wires, the only factor that affects the motor PWM wave is the weight of the clothes, because after the motor is disconnected from the neutral and live wires, the rotation of the motor relies on the inductive electromotive force generated inside it. At this time, if the clothes are heavy, the clothes will have inertia when they rotate, and the inertia is large when the clothes are heavy, so Figure 3 The total duration of the high level of the PWM wave output from the output end of the weighing circuit will also increase, so the corresponding weight can be obtained after processing by the chip; and when the clothing is lighter, the inertia generated by the clothing when it rotates is relatively small, so the total duration of the high level of the PWM wave detected by the chip will also be reduced accordingly, and the corresponding weight can be obtained after processing by the chip.

[0071] In an implementation of the embodiment of the present invention, determining the moisture content of the clothes in S2 includes steps A1 to A2, wherein:

[0072] A1, detecting water volume information and / or clothing material information in the tub;

[0073] A2, determining the moisture content of the clothes according to the water volume information and / or the clothing material information.

[0074] When there is water in the barrel, the clothes in the barrel will absorb the water. If the clothes are weighed directly at this time, the weighing value will inevitably be too high, thereby affecting the amount of water intake. The weighing method provided in the embodiment of the present invention first determines the moisture content of the clothes, then controls the clothes treatment barrel to drain water until the water in the barrel is emptied, and then weighs the clothes using the weighing circuit, and calculates the actual weight of the clothes through the weighed weight m and the moisture content K. This solves the problem of the current weighing method being overloaded and time-consuming, and does not rely on sensors, saving the cost of sensors.

[0075] The moisture content of clothing is an experimental value, which is related to the amount of water in the barrel and the material of clothing. The higher the water level in the barrel, the higher the moisture content of clothing, and the lower the water level in the barrel, the lower the moisture content of clothing; considering that the water absorption of clothing of different materials is different, the stronger the water absorption of clothing materials, the greater the moisture content of clothing, and the poorer the water absorption of clothing materials, the lower the moisture content of clothing.

[0076] In an implementation of the embodiment of the present invention, determining the moisture content of clothing according to water volume information and / or clothing material information in A2 includes A21-A22, wherein:

[0077] A21, searching the moisture content of the clothes corresponding to the water amount information from a corresponding relationship table of water amount information and moisture content of clothes;

[0078] Specifically, after obtaining the water volume information, the moisture content of the clothes corresponding to the water volume information is searched from the water volume information-water content of clothes correspondence table; several water level gears can be pre-set, and different water levels correspond to different moisture contents of clothes, or different moisture contents of clothes can be corresponded based on the original water level gear of the clothes treatment barrel;

[0079] Or, A22, look up the corresponding relationship table of clothing material information-water level information-clothing moisture content to obtain the corresponding clothing moisture content.

[0080] Specifically, after determining the clothing material information and the water level information, the corresponding clothing moisture content is obtained by looking up the clothing material information-water level information-clothing moisture content correspondence table; wherein the stronger the water absorption of the clothing material and the higher the water level, the greater the moisture content of the clothing; conversely, the weaker the water absorption of the clothing material and the lower the water level, the smaller the moisture content of the clothing.

[0081] In an implementation of the embodiment of the present invention, determining the actual weight of the clothes according to the moisture content of the clothes and the weight measured by the weighing circuit includes:

[0082] M = mm × K;

[0083] Among them, M represents the actual weight of the clothes, m represents the weight measured by the weighing circuit, and K represents the moisture content of the clothes.

[0084] Specifically, when the user washes clothes and weighs the clothes, first check whether there is water in the barrel. If there is water, the weighing method of water in the barrel is performed, that is, the amount of water in the barrel is first detected by the water level sensor, and the moisture content K of the clothes corresponding to the amount of water is obtained (the moisture content K of the clothes is obtained in the previous experiment), and then the water is drained and weighed, and then the actual weight M=mm×K is calculated by the weighed weight m and the moisture content K. If there is no water in the barrel, weighing is performed directly, that is, on the basis of the existing weighing circuit, the main chip controls the zero and live wires of the motor to be disconnected, and this weighing circuit is used to detect the total high-level duration of the PWM wave after the motor disconnects the zero and live wires, and the weight of the clothes is obtained according to the total high-level duration of the PWM wave.

[0085] A second aspect of an embodiment of the present invention provides an electronic device, the electronic device comprising: a memory for storing computer instructions; a controller for calling and executing the computer instructions stored in the memory to implement the method provided in any of the above embodiments.

[0086] A third aspect of an embodiment of the present invention discloses a weighing device for a clothes processing device, wherein the clothes processing device comprises a weighing circuit, and the weighing device comprises:

[0087] A water level detection circuit is used to detect whether there is water in the clothing treatment barrel when the clothing in the clothing treatment barrel needs to be weighed;

[0088] The controller is connected to the water level detection circuit and the weighing circuit respectively. The controller is used to:

[0089] When water is detected in the barrel, the moisture content of the clothes is first determined, and then the clothes treatment barrel is controlled to drain water, and after the drainage is completed, the clothes in the barrel are weighed using a weighing circuit; the actual weight of the clothes is determined according to the moisture content of the clothes and the weight measured by the weighing circuit;

[0090] Or, when it is detected that there is no water in the barrel, the clothes in the barrel are weighed using a weighing circuit.

[0091] Figure 3 The weighing circuit provided in the embodiment of the present invention is connected to both ends of the motor. The principle of the weighing circuit is: taking advantage of the fact that the motor is an inductive load, the total duration of the high level of the PWM wave output by the weighing circuit after the motor is powered off is used to weigh the clothes. Figure 3 When the motor is working, a series of PWM waves are output at the output end by utilizing the function of two transistors, and the output end is connected to the chip port. By using the chip to process this PWM wave, the total duration of the PWM wave high level can be obtained, and then the corresponding weight of the clothes can be obtained.

[0092] Furthermore, the weighing device also includes a zero-live line control circuit, the zero-live line control circuit is connected to the zero line terminal and the live line terminal of the motor, and the weighing circuit is connected to the forward rotation terminal and the reverse rotation terminal of the motor;

[0093] The controller sends a preset control signal to the zero-live-wire control circuit so as to control the zero line and the live line of the motor to be disconnected by the zero-live-wire control circuit in response to the preset control signal;

[0094] The weighing circuit is used to obtain the rotation information of the motor after power failure, and the weight of the articles in the barrel is determined based on the rotation information.

[0095] The rotation information includes any one or more of the number of pulses, the number of zero crossings and the total duration of high level after the motor is powered off. In this embodiment, it is preferred to count the total duration of high level output by the weighing circuit after the motor is powered off for weighing.

[0096] The weighing device provided by the embodiment of the present invention includes a weighing circuit, a water level detection circuit and a controller. When the motor is a fixed frequency motor, the weighing circuit is connected to the forward end and the reverse end of the motor. When weighing is required, the water level detection circuit is first used to detect whether there is water in the barrel. If there is water, the weighing method of the water content in the barrel is executed, that is, the water volume in the barrel is first detected by the water level sensor, and the moisture content K of the clothes of the corresponding water volume (the experimental value of the moisture content K of the clothes) is obtained, and then the clothes treatment barrel is drained. After the drainage is completed, the clothes are weighed, and the actual weight M=mm×K of the clothes in the barrel is calculated by the weighed weight m and the moisture content K; if there is no water in the barrel, the weighing is directly executed, that is, on the basis of the existing weighing circuit, the main chip controls the zero and live wires of the motor to be disconnected, and the weighing circuit is used to detect the total high level time of the PWM wave after the motor disconnects the zero and live wires, and the weight of the clothes is obtained according to the total high level time of the PWM wave. In this way, the purpose of double protection can be achieved, and other circuits can be avoided when only the live wire is disconnected, resulting in normal output of the motor and inaccurate weighing. It can also solve the problem of high weighing values ​​caused by weighing in the barrel before power-on. It can also effectively reduce the weighing time, improve the efficiency of clothing washing, and enhance the user experience. This weighing method is simple, convenient and low-cost.
