The washing machine is an important household appliance, wherein a washing machine motor is an important component on the washing machine, and the washing machine mainly depends on the rotation of the washing machine motor to complete various works.
In the working process of the existing washing machine, the washing machine controls the rotation of the drum of the washing machine by controlling the rotation of the motor of the washing machine, and further realizes the functions of washing, rinsing, spin-drying and the like of the washing machine by matching with other parts of the washing machine.
In the operation process of the washing machine, the motor of the washing machine can continuously rotate for a long time, and at the moment, the motor of the washing machine is easy to generate heat due to overhigh load, so that overheating protection is triggered to influence the normal work of the washing machine.
The inventor researches and finds that the operation mode of the washing machine can be adjusted according to the load state of the washing machine motor, the load of the washing machine motor is reduced, and the washing machine motor is prevented from triggering the overheat protection. Therefore, the washing machine motor control method provided by the scheme of the invention is used for carrying out motor load management on a running washing machine, firstly, the current load state of the washing machine motor is obtained to determine whether the washing machine motor is in an overload state, and if the washing machine is in the overload state, the current running mode of the washing machine is adjusted to avoid the situation that the washing machine motor continues overload running to trigger overheating protection, so that the probability that the washing machine motor triggers the overheating protection is reduced, the normal running of the washing machine is prevented from being influenced, and the working efficiency of the washing machine is improved.
The washing machine motor control method provided by the embodiment of the present application may be executed by the washing machine motor control device provided by the embodiment of the present application, the washing machine motor control device provided by the embodiment of the present application may be a part of a washing machine, fig. 1 is an exemplary application scenario diagram provided by the present disclosure, as shown in fig. 1, the washing machine provided by the present embodiment includes a washing machine motor control device 1 and a washing machine motor 2, wherein the washing machine motor control method provided by the present embodiment may be applied to the washing machine motor control device 1, and the washing machine motor control device 1 may send a control signal to the washing machine motor 2 to control the operation of the washing machine motor 2. The embodiment of the present application does not limit the type of the washing machine, and for example, the type of the washing machine may include a pulsator type washing machine, a drum type washing machine, an agitator type washing machine, and the like.
Specifically, the washing machine motor control device 1 acquires the current load state of the washing machine motor 2, and adjusts the operation mode of the washing machine if the washing machine motor 2 is determined to be in an overload state according to the current load state of the washing machine motor 2, so that the washing machine motor 2 is in a normal load state in the adjusted operation mode.
The technical solution of the present invention will be described in detail below with specific examples. The following several specific embodiments may be combined with each other, and details of the same or similar concepts or processes may not be repeated in some embodiments.
Example one
Fig. 2 is a flowchart of a washing machine motor control method according to an embodiment of the present disclosure, and as shown in fig. 2, an execution main body of the embodiment is a washing machine motor control device, and the washing machine motor control method according to the embodiment of the present disclosure includes:
and S21, acquiring the current load state of the motor of the washing machine.
The current load state comprises an overload state and a normal load state, wherein the overload state represents that the washing machine motor is in a working state with larger running power, and the normal load state represents that the washing machine motor is in a working state with running power within a normal range.
Since the motor of the washing machine may generate heat problems and even trigger the overheating protection during a long time operation, it is possible to determine whether the washing machine has a risk of triggering the overheating protection by acquiring a current load state of the motor of the washing machine.
In this embodiment, when the current load state of the washing machine motor is obtained, the washing machine motor control device may detect the current operating power of the washing machine motor, and determine the current load state of the washing machine according to the current operating power of the washing machine motor, or the washing machine motor control device may detect the current of the washing machine motor, and determine the current load state of the washing machine according to the current of the washing machine motor, or the washing machine motor control device may detect the resistance value of the thermistor disposed on the washing machine motor control device, and since the thermistor exhibits different resistance values when the washing machine motor is in different load states, the current load state of the washing machine is determined according to the resistance value of the thermistor, which is not limited in this embodiment.
Specifically, first, the washing machine motor control apparatus detects information capable of determining a current load state of the washing machine motor, and then, the washing machine motor control apparatus determines whether the washing machine motor is currently in an overload state or a normal load state according to the detected information.
And S22, if the current load state is an overload state, adjusting the current operation mode of the washing machine so that the motor of the washing machine is in a normal load state in the adjusted operation mode.
Because the current load state of the washing machine motor is the overload state, the washing machine can generate serious heat, and the risk of triggering the overheating protection is high, the current operation mode of the washing machine needs to be adjusted, the washing machine motor is controlled to be converted into the normal operation state from the overload state, and the phenomenon that the triggering of the overheating protection causes the work interruption of the washing machine and influences the normal operation of the washing machine is avoided.
For example, the current operation mode of the washing machine may include a fast washing mode, a standard washing mode, a fast rinsing mode, a standard rinsing mode, a spinning mode, and the like.
In this embodiment, when the current operation mode of the washing machine is adjusted, the current operation mode of the washing machine may be obtained, and the current operation mode is adjusted to the low power mode in the current operation mode, so as to integrally adjust the operation mode of the washing machine, or a control instruction of an overload state of the washing machine in the current operation mode is obtained, only the motor of the washing machine is adjusted, and operations of other components are not adjusted, so that the motor of the washing machine returns to a normal operation state, which is not limited in this embodiment.
The embodiment provides a washing machine motor control method, which comprises the steps of obtaining the current load state of a washing machine motor; and if the current load state is an overload state, adjusting the current operation mode of the washing machine so as to enable the motor of the washing machine to be in a normal load state in the adjusted operation mode. The clothes processing method provided by the embodiment is used for carrying out motor load management on a running washing machine, firstly, the current load state of the washing machine motor is obtained to determine whether the washing machine motor is in an overload state, if the washing machine is in the overload state, the current running mode of the washing machine is adjusted, the situation that the washing machine motor continuously runs in the overload state to trigger overheating protection is avoided, the probability that the washing machine motor triggers the overheating protection is reduced, the normal running of the washing machine is prevented from being influenced, and the working efficiency of the washing machine is improved.
On the basis of the above embodiment, in order to accurately obtain the current load state of the washing machine motor, in an optional implementation, the washing machine motor control device further comprises a thermistor; the thermistor presents different resistance values when the washing machine motor is in different load states, and the current load state of the washing machine motor can be determined by detecting the current resistance value of the thermistor.
Since the environmental temperature changes due to different heat generation amounts when the washing machine motor is in different load states, the thermistor is used for sensing the environmental temperature of the washing machine motor in an operating environment, for example, when the washing machine motor is in an overload state, the environmental temperature rises, and the resistance value of the thermistor decreases, so that the current load state of the washing machine motor can be determined by detecting the current resistance value of the thermistor.
That is, when the washing machine motor control device acquires the current load state of the washing machine motor, it needs to detect the current resistance value of the thermistor, and determine the current load state of the washing machine motor according to the current resistance value.
Specifically, after detecting the current resistance value of a thermistor, a washing machine motor control device determines the current load state of a washing machine motor according to the current resistance value of the thermistor by a first method of calculating the resistance value change degree of the thermistor and then determining the current load state of the washing machine motor according to the resistance value change degree of the thermistor; the second method is to determine the current load state of the washing machine motor according to the resistance interval of the thermistor.
To better illustrate how the present embodiment determines the current load state of the washing machine motor, the following further describes how to determine the current load state of the washing machine motor according to the current resistance value of the thermistor, taking the above two methods as examples:
the first method, calculating the resistance change degree of the thermistor, and determining the current load state of the washing machine motor according to the resistance change degree of the thermistor, specifically comprises: calculating a resistance reduction rate of the current resistance of the thermistor relative to a nominal resistance of the thermistor; judging whether the resistance value reduction rate is greater than a preset reduction rate threshold value or not; if so, determining that the current load state of the washing machine motor is an overload state.
The nominal resistance value is the resistance value of the thermistor surface, namely the resistance value of the thermistor under the condition of no heat generation.
That is, it may be determined whether the current load state of the motor of the washing machine reaches the overload state according to a magnitude relation between a resistance reduction rate of the current resistance value of the thermistor with respect to the nominal resistance value of the thermistor and a preset reduction rate threshold.
For example, the nominal resistance of the thermistor is 50K ohms, the preset reduction rate threshold is 30%, the current resistance of the thermistor is detected to be 32K ohms, the resistance reduction rate is calculated to be (50K-32K)/50K × 100% ═ 36%, the resistance reduction rate 36% is greater than the preset reduction rate threshold 30%, and the current load state of the washing machine motor is determined to be the overload state.
The second method, which determines the current load state of the washing machine motor according to the resistance interval of the thermistor, specifically includes: determining a resistance value interval where the resistance value of the thermistor is located; determining the current load state of the washing machine motor according to a preset resistance value load matching relation; the resistance value load matching relationship comprises the load state of the washing machine motor when the resistance value of the thermistor is in different resistance value intervals.
That is, the resistance intervals in which the resistance values of the thermistor are located are different, which indicates that the washing machine motor is in different load states, so that the current load state of the washing machine motor can be determined according to the resistance interval in which the resistance values of the thermistor are located.
For example, the resistance interval includes 0-20K ohm, 20K ohm-35K ohm and 35K ohm-50K ohm, wherein 0-20K ohm corresponds to the fault state, 20K ohm-35K ohm corresponds to the overload state, 35K ohm-50K ohm corresponds to the normal load state, the current resistance of the thermistor is 32K ohm, the located resistance interval is 20K ohm-35K ohm, and the current load state of the washing machine motor is determined to be the overload state according to the resistance load matching relationship.
On the basis of determining that the current load state of the washing machine motor is an overload state, in order to avoid the washing machine motor from triggering overheating protection, the current operation mode of the washing machine is adjusted, so that the washing machine motor is in a normal load state in the adjusted operation mode.
Specifically, if the current load state is an overload state, the current operation mode of the washing machine is acquired; calling a control instruction of the overload state of the washing machine in the current operation mode according to a preset operation mode instruction library, and controlling the washing machine to execute the control instruction; wherein, aiming at any operation mode of the washing machine, the operation mode instruction library is prestored with a control instruction of an overload state in any operation mode and a control instruction of a normal load state in any operation mode.
That is, each washing machine has a corresponding control command in an overload state and a corresponding control command in a normal load state in an operation mode, and the control commands are stored in a preset operation mode command library for the washing machine motor control device to call. And when the motor of the washing machine is in different load states, calling a corresponding control command.
For example, the current operation mode of the washing machine is obtained as a standard washing mode, a control instruction of an overload state in the standard washing mode is called from a preset operation mode instruction library, and the washing machine is controlled to execute the control instruction, so that the motor speed of the washing machine is reduced on the basis of keeping the standard washing mode, for example, the motor speed of the washing machine is reduced from 70r/min to 60r/min, or the washing machine motor is intermittently rotated, for example, the washing machine motor is stopped for 3min after being washed for 5min, and washing and stopping are alternately performed, which is not limited in this embodiment, and finally, the operation power of the washing machine motor is controlled to be reduced, so that the washing machine is in a normal load state.
In addition, when the current load state of the washing machine motor is the normal load state, the washing machine motor does not trigger the risk of overheat protection, and the current operation mode of the washing machine does not need to be adjusted.
Specifically, the current load state of the motor of the washing machine is obtained by the method described in the foregoing embodiment, and the specific method is as described above, and is not described here again, and if the current load state is the normal load state, the current operation mode of the washing machine is maintained.
The embodiment provides a washing machine motor control method, which comprises the steps of detecting the resistance value of a thermistor arranged on a washing machine motor control device, determining the current load state of a washing machine motor according to the resistance value reduction rate of the thermistor or a preset resistance value load matching relation, if the current load state is an overload state, obtaining the current operation mode of the washing machine, calling a control instruction of the overload state in the current operation mode from a preset operation mode instruction library, controlling the washing machine to execute the control instruction, so that the washing machine enters a normal load state, if the current load state is the normal load state, keeping the current operation mode of the washing machine, realizing the adjustment of the operation mode of the washing machine according to different load states of the washing machine motor, so that the washing machine is in the normal load state, and reducing the probability of triggering overheat protection of the washing machine motor, so as to avoid influencing the normal operation of the washing machine and improve the working efficiency of the washing machine.
