Description

A kind of resonance washing machine

Technical field

The utility model relates to a kind of household electrical appliance, particularly a kind of washing machine.

Background technology

At present no matter all washing machines are cabinet-type or roller, all are to utilize the principle of stirring, utilize between the clothing or clothing and barrel wall between mutual friction mutually, finish the cleaning of clothing, this can cause the wearing and tearing of clothing.Washing machine has become ripe through years of development, does not almost have what innovation on basic structure.Each major company of the world, no matter product energy-conservation or efficient aspect effort, all be on existing machine construction, to do some improvement, all do not have revolutionary innovation, the performance of washing machine does not take place significantly to improve and improve yet.

The utility model content

Utility model purpose: at the problems referred to above, the purpose of this utility model provides a kind of novel washing machine, innovate from operation principle, simplify washing machine structure, reduce manufacturing cost, improve washing efficiency, guarantee uniformity, the wearing and tearing of minimizing clothing, the minimizing wash time of clothes washing, thereby reduce the laundry cost.

Technical scheme: a kind of resonance washing machine, comprise staving, base, also comprise support spring, electrodynamic shaker, sensor, microprocessor, described base and described staving bottom are connected and fixed by described support spring, described electrodynamic shaker directly links to each other with described staving with described sensor, and described electrodynamic shaker and described sensor are by described microprocessor control.

Best, described electrodynamic shaker is the eccentric wheel electrodynamic shaker.

Best, described sensor is an acceleration transducer.

The utility model washing machine structure is by making staving and support spring produce resonance motion, thereby the clothing that makes staving inside significantly moves mutually with the water generates of having dissolved washing agent and little carbonated drink bubble of friction and liquid resonance back generation, washing clothes is removed the dirt on the clothing.

Beneficial effect: compared with prior art, the utility model has the advantages that and utilize resonance principle design washing machine structure and operation control method, make washing machine washing clothes under optimum Working, improve clean result and washing efficiency, guarantee uniformity, the wearing and tearing of minimizing clothing, the minimizing wash time of clothes washing, thereby reduce the laundry cost, simplify washing machine structure, manufacturing cost also reduces.

The specific embodiment

Below in conjunction with the drawings and specific embodiments, further illustrate the utility model, should understand these embodiment only be used to the utility model is described and be not used in the restriction scope of the present utility model, after having read the utility model, those skilled in the art all fall within the application's claims institute restricted portion to the modification of the various equivalent form of values of the present utility model.

As shown in Figure 1, a kind of resonance washing machine, comprise staving 1, base 2, support spring 3, eccentric wheel type electrodynamic shaker 4, acceleration formula sensor 5, microprocessor 6, base 2 is connected and fixed by support spring 3 with staving 1 bottom, electrodynamic shaker 4 directly links to each other with staving 1 with sensor 5, and electrodynamic shaker 4 and sensor 5 are by microprocessor 6 controls.

The operation control method of above-mentioned a kind of washing machine that resonates may further comprise the steps:

(1) clothing, water, washing agent are put into staving, covered and enclosed;

(2) start earlier electrodynamic shaker, by predefined basic, normal, high different frequency or random frequency, staving is implemented initially to add to shake, thereby make support spring begin vibration, the vibration signal of perception is fed back to microprocessor in real time by sensor in company with staving;

(3) microprocessor will and carry out Digital Signal Processing to the sampling of the vibration signal of sensor feedback, obtain the resonant frequency of vibrational system under the work at present load that staving and support spring constitute, and control, drive electrodynamic shaker as feedback with this resonant frequency, make vibrational system under this resonant frequency, violent oscillatory motion take place, thereby make in the staving washing that fully rubs of clothing and the water that has dissolved washing agent.

Control flow as shown in Figure 2, when washing machine began to do washing the work period, microprocessor started earlier electrodynamic shaker, by electrodynamic shaker staving and inner clothing was applied the vibration source of different frequency, the beginning initial vibration, support spring produces vibration with staving.Meanwhile, the sensor on the staving feeds back to microprocessor with the vibration signal of the staving of perception.Microprocessor to sampling of this vibration signal and Digital Signal Processing after, as vibration signal is carried out digital Fourier's computing etc., just can obtain the current resonant frequency of vibrational system of staving and support spring formation.This resonant frequency depends primarily on weight and the design weight of washing machine structure itself and the used factors such as support spring rigidity of clothing, water, washing agent in the current staving.Behind the resonant frequency of determining the vibrational system current state, microprocessor is just controlled the driving frequency of electrodynamic shaker with this resonant frequency, excite whole vibrational system to maintain vibration under this resonant frequency, thereby with less driving energy, produce and induce the resonance motion significantly of staving and inner clothing, thereby make clothing, water and washing agent combination move mutually and rub, and make the liquid in the bucket produce microbubble and clothing interaction, reach the purpose that clothing cleans with amplitude peak.

At first obtain the resonant frequency of vibrational system and in washing process, keep vibrational system and under this resonant frequency, vibrate by just shaking.In order to guarantee that washing machine maintains the resonance state vibration all the time, microprocessor is in the laundry work period, sensor is constantly gathered new vibration signal, and it is handled, constantly obtain new changing value of its resonant frequency of vibrational system and possible drift, microprocessor feeds back to electrodynamic shaker with this variation then, change and adjust the driving frequency of electrodynamic shaker, form a feedback control system with this, guarantee that vibrational system maintains the resonance motion state all the time in the laundry work period, obtain best clean result and minimum energy consumption.

In laundry processes, if need to reduce the Oscillation Amplitude of washing machine, microprocessor also can allow it depart from the current resonant frequency of vibrational system by regulating the vibration frequency of electrodynamic shaker, reduces Oscillation Amplitude with this, thereby reduces the fierce degree of laundry.

In addition, thereby drive the purpose that electrodynamic shaker makes washing machine generation resonance in order to reach, microprocessor will be measured the current vibration frequency and the phase angle of vibrational system according to the vibration signal of sensor feedback, and according to this current vibration frequency and phase angle, control and regulate electrodynamic shaker, make electrodynamic shaker with resonant frequency exciting vibrational system, keep with the excited vibration system with this and under resonant frequency, maximum resonance takes place.
