The specific embodiment
Reach embodiment with reference to the accompanying drawings and describe washing machine and the control method thereof that possesses vibration inductor of the present invention in detail.
As Fig. 2, Fig. 3 and shown in Figure 4, structure of the present invention includes: the microprocessor 10 of motor control processor 110 is housed, and it can control the motor 2 of BLDC motor of the washing drum of the cylinder of rotatable drum formula washing machine or pulsator washing machine; Receive the controller 1 that above-mentioned motor control processor 110 signals are controlled the motor control loop 11 of motor 2 as containing, controller 1 has the accelerometer 14 that can respond to dynamic acceleration and static acceleration simultaneously and can make the user set the vibration/noise setting apparatus 125 of vibration and noise allowed band arbitrarily.
The object lesson of above-mentioned accelerometer 14 has MEMSIC formula sensor (sensor of MEMSIC company exploitation).
Above-mentioned accelerometer 14 is a kind of semiconductor transducers, its operation principle is as follows: the air in semiconductor inside is heated under the state that rises to the top, tilt washer or vibration space-time its part difference that can relate to can change along with the air of the part that is touched changes its quantity of electric charge.Promptly because of the difference of gradient or vibratory output, the quantity of electric charge of air position and sensor internal changes and detects these variable quantities and just can obtain gradient or vibratory output.
And above-mentioned microprocessor 10 is provided with vibration induction processor 100.
The vibration/noise that vibration/noise setting apparatus 125 can be set the vibration/noise scope arbitrarily by vibration/noise display window 125a that shows the vibration/noise size and user is set button 125b and is formed.
The operation of the product of the present invention of Gou Chenging is as follows as mentioned above.
In the past, the unbalanced of washing machine was detected before entering formal dehydration, and determined dewatering speed to carry out dehydration thus.
The present invention is not that the dewatering speed with once decision continues dehydration, but in dehydration, with vibratory output change and dewatering speed that vibratory output is changed dewater.
For example, if the permission vibratory output when dewatering speed is 1200RPM is made as 100, if vibratory output surpasses at 100 o'clock, washing machine of the present invention automatically dewaters less than 100 dewatering speed with vibratory output.
If vibratory output is under allowing vibratory output the time, just the dewatering speed with initial setting dewaters.
In addition, the present invention can operate the setting button 125b that is installed on the vibration/noise setting apparatus 125, and the user directly sets the vibration and the noise allowed band of product, so the control low noise, low vibration becomes possibility, thereby improves the quality of products.
The chart of the vibration control amount that Fig. 4 person of being to use can set, the vibration control degree of selecting with the user is a standard or quiet or very quiet, the vibratory output of its control also can be different, and selecteed vibration/noise degree shows by vibration/noise display window 125a.
In the accelerometer 14 that handle is commonly used recently according to the present invention, the accelerometer 14 that can respond to dynamic acceleration and static acceleration simultaneously is installed in the controller 1, when dewatering, detect dynamic acceleration and handled by above-mentioned accelerometer 14, if reduce dewatering speed when vibrating outside specified scope, thereby realize low noise, low vibration according to its result.
Possess in the washing machine of vibration inductor, by the motor 2 of 110 control swing rollers of the motor control processor in the microprocessor 10 or washing drum, when motor control loop 11 is received the signal of motor control processor 110, the control 2 rotary speed stages of motor; Then, when dewatering, induction dynamic acceleration or static acceleration are handled the signal of sensing, and are confirmed externally that by this accelerometer 11 display 12 of vibration of washing machine is shown the stage simultaneously on the accelerometer 14 on the motor control processor 110 of microprocessor 10; According to the result on the above-mentioned motor control processor 110, determine to keep or change the 2 rotary speed stages of motor.
At this moment, the vibration induction processor 100 of above-mentioned microprocessor 10 is transformed into the detection signal that detects the data signal and the output of vibration of washing machine amount on accelerometer 14.
Therefore, the user can regulate the vibration/noise allowed band arbitrarily by the vibratory output of confirming that vibration/noise display window 125a shows.
The warning tones generator 13 of the sound that gives a warning automatically when vibration surpasses certain limit also can be installed on the above-mentioned controller 1 in addition.
Therefore, when when using product, surpassing certain oscillating region because of the vibration of a variety of causes washing machine, not only detect vibratory output, it is presented at the vibration/noise display window with data signal, and the warning tones generator sends song and can point out the user automatically by accelerometer 14.
The rotary speed of motor 2 can be kept and be lower than under vibration and the certain standard of noise, also can be maximum speed in the speed of the certain standard that is lower than vibration and noise.
Example as above-mentioned warning tones generator can adopt buzzer or quarter-bell etc.In display 12, also be provided with washing setting apparatus 120 and dryer settings device 121, and branch is to be provided with button.
The present invention is not limited to the above embodiments, as long as be no more than the diversified variation of technology category form of the present invention or revise all within the protection of this claim.
The present invention is not limited to tumbling-box washing machine, also can be widely used in general pulsator washing machine and other need the household electrical appliance of vibration induction.
