Detailed Description
In order to make the technical solutions of the present invention better understood by those skilled in the art, the technical solutions of the present invention are further described below by way of specific embodiments with reference to the accompanying drawings.
The embodiment provides a resonance prevention control method for a combined household appliance, which comprises the steps of monitoring the amplitude of each electric appliance, comparing the amplitude with the preset amplitude corresponding to the electric appliance, and adjusting the motor rotating speed of the electric appliance according to the comparison result to prevent resonance. According to the method for preventing the resonance of the combined household appliance, the amplitude of the detected electric appliance is compared with the preset amplitude, so that the phenomenon that the combined household appliance is changed into resonance when in work when the amplitudes of the two electric appliances reach the preset amplitude corresponding to the electric appliance can be effectively prevented, and the combined household appliance can work normally and stably.
The adjusting the rotation speed of the motor of the electric appliance according to the comparison result to prevent resonance comprises:
and if the amplitude of at least one electric appliance is the same as the preset amplitude corresponding to the electric appliance, adjusting the rotating speed of the motor of the electric appliance to prevent resonance.
Further, in this embodiment, the explanation "if the amplitude of at least one electrical appliance is the same as the preset amplitude corresponding to the electrical appliance, the rotating speed of the motor of the electrical appliance is adjusted to prevent resonance" is that:
if the amplitude of one electric appliance is the same as the preset amplitude corresponding to the electric appliance, reducing the motor rotating speed of other electric appliances;
and if the amplitudes of the two electrical appliances are the same as the corresponding preset amplitudes of the electrical appliances, controlling the motor rotating speed of the electrical appliances according to preset conditions.
The first condition is that the amplitude of one of the two electrical appliances is the same as the preset amplitude of the electrical appliance; the amplitudes of the two electrical appliances are the same as the corresponding preset amplitudes of the two electrical appliances (each electrical appliance has one preset amplitude). If the amplitudes of the two electrical appliances are different from the preset amplitudes corresponding to the two electrical appliances, the comparison result is not in any condition.
Because there is the condition that the amplitude of two electrical apparatus reaches the predetermined amplitude simultaneously, for this reason, when the amplitude of two electrical apparatus reached the predetermined amplitude simultaneously, the motor speed of controlling electrical apparatus according to predetermineeing the condition includes:
judging the weight of the washings of the two electric appliances, and adjusting the rotating speed of the motor of the electric appliance with larger weight of the washings. The adjustment of the motor speed means that the motor speed of the electric appliance with heavy weight of the washings is reduced. Thereby reducing the amplitude of the appliance. Of course, in other embodiments, the motor speed of the appliance with the smaller weight of the laundry may be reduced.
Of course, the motor speed of the electrical appliance can be controlled according to the preset condition, and the motor speed of the electrical appliance with large eccentricity can be adjusted by judging the eccentricity of the two electrical appliances.
Because the electric appliance is provided with the detection mechanism for detecting whether the washing of the electric appliance is eccentric, the method can realize the purpose of detecting the eccentric amount without adding parts to the electric appliance, and further can adjust the rotating speed of the motor according to the eccentric amount. Simultaneously, by detecting the eccentric amount, the amplitude of the electrical appliance with large eccentric amount can be effectively reduced, and the combined household appliance can be prevented from rapidly achieving polarization.
Because there is still the problem that needs to continue working in the electrical apparatus that reduces motor speed, for this reason, still include after the motor speed of adjusting electrical apparatus according to the comparative result prevents resonance in this embodiment:
detecting the amplitude of an electric appliance of which the motor rotating speed is not adjusted, and if the amplitude of the electric appliance is smaller than the preset amplitude, increasing the motor rotating speeds of other electric appliances to restore the running state;
if the amplitude of the electric appliance is not smaller than the preset amplitude, the rotating speed of the motors of other electric appliances is reduced.
The step can reduce resonance without influencing the work of other electrical appliances, thereby realizing the separate increase of the working amplitudes of the two electrical appliances and preventing the two electrical appliances from realizing resonance when the two electrical appliances reach the preset amplitude of resonance. It should be noted that the predetermined amplitude for each machine is obtained from a number of trials, not any one amplitude specified.
It should be noted that the combined household electrical appliance proposed in this embodiment refers to two electrical appliances stacked one above the other or two electrical appliances placed side by side and contacting each other. The two electric appliances can be controlled by respective controllers or by one controller. When the two electric appliances are controlled by respective controllers, data transmission is carried out between the two electric appliances through the communication device, so that the controller can obtain the amplitude of the other electric appliance, and the electric appliances can be controlled to act according to the obtained amplitude.
The combination household appliance comprises two washing drums which are arranged up and down, the detailed description is carried out by taking the example as an example, in order to facilitate the distinguishing, the two washing drums are named as a drum A and a drum B respectively in the embodiment, when the two washing drums simultaneously realize the dehydration task, the amplitudes of the two washing drums in the rotation process respectively and simultaneously reach the preset amplitudes to generate resonance, in order to solve the problem, the amplitudes of the two washing drums are monitored, the amplitudes of the two washing drums are the same as the preset amplitudes, the amplitudes of the two washing drums are not reached, the rotation speed of the unaffiliated drum B is reduced, when the amplitudes of the two washing drums are lower than the preset amplitudes, the rotation speed of the drum B is increased again, and the normal work of the drum B is realized.
When the amplitudes of the drum A and the drum B reach the preset amplitude simultaneously, the weights of the laundry washed by the drum A and the drum B or the eccentric amounts of the laundry washed by the drum A and the drum B are compared, the drum with the larger weight of the laundry or the larger eccentric amount of the laundry keeps rotating, and the other drum reduces the rotating speed.
As shown in fig. 1, the anti-resonance control method for the combined household appliance specifically comprises the following steps:
s1, the combined household appliance starts to work and the amplitude of each appliance is detected;
s2, comparing whether the amplitude of any electric appliance is the same as the preset amplitude of the electric appliance or not; if not, returning to S1;
s3, if yes, judging whether the amplitudes of the two electric appliances are the same as the preset amplitudes corresponding to the electric appliances or not;
s4, if the amplitudes of the two electric appliances are the same as the corresponding preset amplitudes of the electric appliances, reducing the motor rotating speed of the electric appliances meeting the preset conditions according to the preset conditions;
s5, whether the amplitude of the electric appliance which does not reduce the rotating speed of the motor is smaller than a preset amplitude or not is judged;
s6, if so, increasing the motor rotating speed of the electric appliance with the reduced motor rotating speed to recover the running state; if not, returning to S3;
s7, if the amplitudes of the two electric appliances are not equal to the preset amplitudes corresponding to the electric appliances, reducing the motor rotating speed of the electric appliances with the amplitudes equal to the preset amplitudes;
s8, whether the amplitude of the electric appliance without the rotation speed of the motor adjusted is smaller than the preset amplitude or not is judged, and if not, the S7 is returned;
and S1, if so, increasing the rotating speed of a motor of another electrical appliance to recover the running state.
The embodiment also provides a combined household appliance, the resonance is prevented by using the anti-resonance control method for the combined household appliance provided by the embodiment, it needs to be noted that each electric appliance is provided with an amplitude detection sensor for detecting the amplitude of the electric appliance during working, the amplitude is transmitted to a controller of the combined household appliance, and the controller controls the rotating speed of the motor of each electric appliance according to the comparison of the transmitted amplitude and the preset amplitude and the comparison structure.
