Technical field
The present invention relates to the washing machine field, control circuit and control method thereof that especially a kind of washing machine speed change is washed.
Background technology
At present, the washing machine on the market is when operation, and the setting of washing current mainly is divided into three types:
The first, by after " power supply " key powers on washing machine, the program that at first needs by selections of " program " key, different programs is solidified different current parameters respectively, and by the washing of " startups " key, the current of maintenance curing always are constant;
The second, by " power supply " key washing machine is powered on behind the option program, different programs is solidified several kinds of different current parameters respectively; By the washing of " startup " key; According to fixing sequential, between several kinds of current parameters of solidifying, switch, make current produce periodic the variation;
The 3rd, by " power supply " key washing machine is powered on behind the option program, according to the water level settings of reality,, wash according to the current parameter that the sequential option program solidifies.
In fact, when the user manually washes clothes, can through changing the washing dynamics, reach the purpose that promotes clean result according to what of washings.So, set type for above-mentioned three kinds, do not change the authority that the washing dynamics is the current parameter to the user, also not according to actual loading, in washing process, change the function of current, well user's hand clothes washing process is not simulated.
Summary of the invention
Primary and foremost purpose of the present invention is to provide a kind of can realize the automatic control to washing machine washings intensity of flow, better the control circuit that the washing machine speed change of detersive efficiency is washed is simulated, improved to user's hand clothes washing process.
For realizing above-mentioned purpose; The present invention has adopted following technical scheme: the control circuit that a kind of washing machine speed change is washed; Comprise main control chip; The signal input part of main control chip links to each other with the flow intensity button, and the signal output part of main control chip links to each other with motor through control circuit, and the load judgment circuit that is used to gather current of electric links to each other with the signal input part of main control chip.
Another object of the present invention is to provide the control method of the control circuit that a kind of washing machine speed change washes, this method comprises the step of following order:
(1) after washing machine powered on, whether the main control chip judges set flow intensity, if judged result is for being, then moved according to this flow intensity through control circuit control motor;
(2) if the judged result of step (1) is not, the current of electric that is then passed through to be gathered by the load judgment circuit is judged load weight, and main control chip is regulated flow intensity according to load weight, controls motor according to this flow intensity action through control circuit.
Can know that by technique scheme the present invention is provided with " flow intensity " button on control panel, supply the user voluntarily flow intensity to be provided with according to clothing.If the user is not provided with flow intensity, then, corresponding flow intensity is set automatically by the size of main control chip according to clothes weight in the washing machine before washing.The present invention has realized the simulation of washing machine to user's hand washing to a certain extent, makes the function hommization of washing machine, has improved detersive efficiency.

The specific embodiment
The control circuit 3 that a kind of washing machine speed change is washed; Comprise main control chip 2; The signal input part of main control chip 2 links to each other with flow intensity button 1; The signal output part of main control chip 2 links to each other with motor 5 through control circuit 3, and the load judgment circuit 4 that is used to gather motor 5 electric currents links to each other with the signal input part of main control chip 2.Described motor 5 is a single-phase asynchronous motor, and described flow intensity button 1 is arranged on the control panel, and is as shown in Figure 1.
In when work, the first, after washing machine powered on, whether main control chip 2 judges set flow intensity, if judged result is for being then to move according to this flow intensity through control circuit 3 control motors 5; The second, if the judged result of the first step is not, motor 5 electric currents that then passed through to be gathered by load judgment circuit 4 are judged load weight, and main control chip 2 is regulated flow intensity according to load weight, move according to this flow intensity through control circuit 3 control motors 5.
Be further described below in conjunction with Fig. 1,2 couples of the present invention.
After washing machine powered on, main control chip 2 judged whether washing procedure brings into operation, if judged result then stops action through control circuit 3 control motors 5 for not, otherwise main control chip 2 continues judges and whether presses flow intensity button 1 to set flow intensity.
When whether 2 couples of users of main control chip set flow intensity and judge; If judges is pressed flow intensity button 1; Flow intensity is provided with; Then by the flow intensity parameter storage of main control chip 2 with user's setting, and with this flow intensity Parameters Transformation is corresponding motor 5 work durations, works according to this work duration through control circuit 3 control motors 5.
When whether 2 couples of users of main control chip set flow intensity and judge; If judges is not pressed flow intensity button 1; Flow intensity is not provided with, then gathers electric current, these motor 5 current conversion are become pulse signal by load judgment circuit 4; Main control chip 2 is judged the weight of washing machine internal burden through this pulse signal; Regulate the flow intensity parameter according to load weight, and be corresponding motor 5 work durations, work according to this work duration through control circuit 3 control motors 5 with this flow intensity Parameters Transformation.
Do not set flow intensity the user; Main control chip 2 is judged load weight automatically, and after the work duration work of control motor 5 according to correspondence, in the process of water inlet washing; Main control chip 2 repeats above-mentioned judgement load weight process; Detect the weight whether current flow intensity parameter meets actual loading in the washing machine in real time, and, be changed to actual flow intensity parameter according to the difference that calculates.That is to say, after washing process in, main control chip 2 detects load weights in real time, according to detected load weight, if deviation is excessive, then the flow intensity parameter is corrected.
