Detailed Description
Referring to fig. 1 to 5 in combination, according to an embodiment of the present invention, a control method of a feedback type ultrasonic washing machine includes: transmitting an ultrasonic signal to the drum underwear 4; receiving an ultrasonic signal fed back by the clothes 4; the output frequency of the ultrasonic vibrator 2 is adjusted according to the ultrasonic signal fed back by the clothes 4.
When the method is used for ultrasonic washing, the output frequency of the ultrasonic vibrator 2 can be adjusted according to the ultrasonic signal fed back by the clothes 4, rather than only selecting a plurality of fixed frequencies set by the washing machine, so that the washing range of the clothes 4 is not limited, the ultrasonic frequency matched with the clothes 4 made of different materials can be selected for washing the clothes 4 made of different materials, the output frequency of the ultrasonic vibrator is determined according to the clothes 4 to be washed, the ultrasonic vibrator can be flexibly adjusted and is not limited by the plurality of fixed frequencies set by the washing machine, therefore, for the clothes 4 made of different materials, the ultrasonic vibrator 2 can be adjusted according to the ultrasonic signal fed back by the clothes 4, the output frequency of the ultrasonic vibrator 2 is more suitable for the optimal washing frequency of the washed clothes 4, the washing efficiency is high, and the washing effect is good.
The step of adjusting the output frequency of the ultrasonic signal according to the ultrasonic signal fed back from the laundry 4 includes: judging whether the output frequency of the ultrasonic vibrator 2 is the optimal cleaning frequency of the clothes 4 or not according to the ultrasonic signal fed back by the clothes 4; when the output frequency of the ultrasonic vibrator 2 does not reach the optimal cleaning frequency of the clothes 4, continuously adjusting the output frequency of the ultrasonic vibrator 2; when the output frequency of the ultrasonic vibrator 2 is the optimum washing frequency of the laundry 4, the ultrasonic washing of the laundry 4 is started.
The system sets the output frequency of the ultrasonic transducer 2 and then the ultrasonic transducer 2 starts to emit ultrasonic waves. The washing machine is internally provided with an ultrasonic sensor 3 for receiving ultrasonic signals reflected by the clothes 4 in the drum and feeding the received ultrasonic signals back to the control system, and the control system can judge whether the output frequency of the current ultrasonic vibrator 2 reaches the optimal cleaning frequency of the clothes 4 or not according to the characteristics of the feedback signals obtained by the ultrasonic sensor 3. The feedback signal is a signal received by the ultrasonic sensor after the ultrasonic wave generated by the ultrasonic vibrator 2 is reflected by the clothes 4, and the feedback signal obtained by reflecting the ultrasonic wave with different frequencies by the clothes 4 has all differences. When the output frequency of the ultrasonic signal does not reach the optimal frequency, the system automatically adjusts the output frequency of the ultrasonic vibrator 2, and the system continues to judge until the output frequency of the ultrasonic vibrator 2 reaches the optimal cleaning frequency; if the frequency is judged to be the optimal frequency, the current output frequency of the ultrasonic vibrator 2 is kept and the washing is started.
In the present embodiment, the method for determining the optimal washing frequency of the laundry 4 includes: b is more than or equal to a × c, wherein a is the amplitude of the ultrasonic signal output by the ultrasonic vibrator 2, b is the amplitude of the ultrasonic signal fed back by the clothes 4, and c is the coefficient of the clothes 4. c is provided by a manufacturer, the manufacturer can obtain the best washing effect only when the relation between the output signal amplitude of the ultrasonic vibrator and the received signal amplitude of the ultrasonic sensor is measured by a large number of experiments, meanwhile, the clothes 4 cannot be damaged, and c is generally smaller than 1.
Preferably, the control method of the feedback type ultrasonic washing machine further comprises: when b < a × c is detected, the output frequency of the ultrasonic vibrator 2 is increased. When b is detected to be less than a, it indicates that the ultrasonic signal output by the current output frequency of the ultrasonic vibrator 2 still reaches the optimal cleaning frequency of the clothes 4, and therefore, the output frequency of the ultrasonic vibrator 2 still needs to be adjusted until b is greater than or equal to a, and the optimal cleaning frequency of the clothes 4 is reached. The laundry 4 is not washed until the optimum washing frequency is not reached.
Before transmitting the ultrasonic signal to the drum underwear 4, the feedback type ultrasonic washing machine control method further comprises the following steps: receiving laundry 4 type information; detecting the presence of the laundry 4; when the clothes 4 exist, detecting the weight of the clothes 4 and injecting corresponding water; when the laundry 4 does not exist, returning to the step of receiving the laundry 4 type information.
The ultrasonic vibrator 2 is mainly used for generating an ultrasonic signal, and the ultrasonic sensor 3 is mainly used for receiving the ultrasonic signal reflected by the clothes 4. As the attenuation of the ultrasonic wave in the air is relatively large, in order to reduce the attenuation of the ultrasonic wave, the invention uses water as the coupling agent. Water needs to be injected into the washing machine drum 1 before washing the laundry 4, the amount of water injected being in direct proportion to the weight of the laundry 4.
Before the step of adjusting the output frequency of the ultrasonic vibrator 2 according to the ultrasonic signal fed back from the laundry 4, the feedback type ultrasonic washing machine control method further includes: an initial output frequency is set according to the received type information of the laundry 4.
The user puts washings into the inner drum 1 of the washing machine, selects the type option of the 4 types of the washings, and in order to avoid the user forgetting to put the 4 types of the washings into the washing machine during washing, a detection module is arranged in the washing machine to automatically judge whether the washings exist, and if the washings do not exist, the user is reminded to return to the beginning. If the washings exist, the next step is carried out: the laundry 4 is weighed. The ultrasonic washing machine is internally provided with a weight sensor, the weight of the clothes 4 in the middle barrel can be accurately detected, and the corresponding water quantity is injected according to the weight of the clothes 4, so that the clothes 4 can be fully soaked, and the optimal washing effect is achieved. After the injection is finished, the next step is carried out: the system sets the output frequency of the ultrasonic vibrator initially according to the type of the clothes 4.
By setting the initial output frequency according to the received type information of the clothes 4, the output frequency of the ultrasonic vibrator 2 can be quickly adjusted to be close to the optimal frequency, so that the output frequency adjustment amount of the ultrasonic vibrator 2 can be reduced, the adjustment efficiency of the output frequency is improved, and the adjustment time is shortened.
According to the embodiment of the invention, the feedback type ultrasonic washing machine adopts the control method of the feedback type ultrasonic washing machine, and comprises a washing machine inner barrel 1, an ultrasonic vibrator 2 and an ultrasonic sensor 3, wherein the ultrasonic vibrator 2 and the ultrasonic sensor 3 are both arranged on the washing machine inner barrel 1, the ultrasonic sensor 3 is used for outputting ultrasonic signals to clothes 4 in the washing machine inner barrel 1, and the ultrasonic sensor 3 is used for receiving the ultrasonic signals fed back by the clothes 4.
