The invention also discloses a control method of the variable-volume washing control circuit of the washing machine. In the invention, the water level key is arranged on the control panel, and washing water level and rinsing water level are set by pressing the water level key down respectively when the washing machine works, so that simulation of manual washing of a user by an impeller type washing machine is realized to a certain extent, functions of the washing machine are humanized, water resource is saved, and washing efficiency is increased.
Description
Technical field
The present invention relates to a kind of washing machine, control circuit and control method thereof are washed in especially a kind of washing machine transfiguration.
Background technology
At present, when the family expenses rotary drum washing machine on the market moves, the setting of water level mainly is divided into two types: after 1, by " power supply " key washing machine being powered on, water level configures, can the manual adjustment water level, by behind the "start" button working procedure, the water level settings of whole service process remains unchanged always, finishes until the program operation; 2, by after " power supply " key powers on washing machine, water level need be waited for artificial setting, if by behind the "start" button working procedure, water level is not set, then utilize fuzzy control technology, judge the weight of washings, select corresponding water level to save as designated water level, finish until the program operation.
In fact when user's hand clothes washing is obeyed, use washing clothes behind the less water-soluble washing powder usually, to improve liquid detergent concentration, the effect when promoting washing is carried out rinsing with more water to clothing afterwards, with the lifting rinsing effect.So above-mentioned two types control method does not all have well user's hand clothes washing process to be simulated.
Summary of the invention
Primary and foremost purpose of the present invention is to provide a kind of washing machine transfiguration of can be better detersive efficiency being simulated, being improved to user's hand clothes washing process to wash control circuit.
For achieving the above object, the present invention has adopted following technical scheme: control circuit is washed in a kind of washing machine transfiguration, comprises main control chip, main control chip and control panel communication, the water level button is set on the described control panel, and main control chip links to each other with level sensor with peripheral electrical equipment respectively.
The invention also discloses the control method that control circuit is washed in a kind of washing machine transfiguration, this method comprises the step of following order:
(1) washing machine powers on, and the user presses the water level button on the control panel, and water level and rinsing water level are set;
(2) washing machine work, level sensor detects actual water level, judges the duty of washing machine, if washing machine is in washing process, judge then whether actual water level reaches water level,, begin washing if judged result for being, then stops into water, otherwise, begin water inlet, stop washing;
(3) if washing machine is in rinse cycle, judge then whether actual water level reaches the rinsing water level, if judged result for being, then stops into water, the beginning rinsing, otherwise, begin water inlet, stop rinsing.
As shown from the above technical solution, the present invention is by being provided with the water level button on control panel, when washing machine is worked, pressing the water level button sets water level and rinsing water level respectively, realized the simulation of rotary drum washing machine to a certain extent to user's hand washing, make the function hommization of washing machine, and saved water resource, improved detersive efficiency.

Fig. 3 is the workflow diagram that the present invention begins to wash.
The specific embodiment
Control circuit is washed in a kind of washing machine transfiguration, comprises main control chip 2, and main control chip 2 and control panel 1 communication are provided with the water level button on the described control panel 1, and main control chip 2 links to each other with level sensor 6 with peripheral electrical equipment 5 respectively.The signal input output end of described main control chip 2 links to each other with peripheral electrical equipment 5 by control circuit 3, feedback circuit 4 respectively, as shown in Figure 1.
Shown in Fig. 2,3, washing machine powers on, and the user presses the water level button on the control panel 1, respectively water level and rinsing water level is set; Washing machine work, level sensor 6 detects actual water level, judges the duty of washing machine, if washing machine is in washing process, judge then whether actual water level reaches the water level of setting,, begin washing if judged result for being, then stops into water, otherwise, begin water inlet, stop washing; If washing machine is in rinse cycle, judge then whether actual water level reaches the rinsing water level of setting, if judged result for being, then stops into water, the beginning rinsing, otherwise, begin water inlet, stop rinsing.
As shown in Figure 2, when washing machine powers on, judge whether washing machine carries out water level settings, if judged result is for denying, then judge the weight of washings in the washing machine, weight automatic setting water level and rinsing water level according to washings that is to say, after washing machine powers on, if water level is not set, then judge the weight of washings in the washing machine, select water level, and setting rinsing water level is a peak level according to the weight of washings; Otherwise, judge the state that the water level button is pressed.Be in the water level set condition if judge the water level button, then set water level, and judge whether the rinsing water level is provided with, if judged result is then set the rinsing water level for not.Be in rinsing water level set condition if judge the water level button, then set the rinsing water level, and judge whether water level is provided with, if judged result is then set water level for not.
As shown in Figure 1, the user is input to the parameter of setting in the main control chip 2 by control panel 1, and through the processing to data, main control chip 2 is by the action sequence of the peripheral electrical equipment 5 of control circuit 3 controls.Simultaneously, main control chip 2 detects the state of peripheral electrical equipment 5 by feedback circuit 4, and passes through the actual water level that level sensor 6 detects in the washing machines.
Transfiguration is washed function water level settings operation principle as shown in Figure 2, the stage that is provided with after washing machine powers on, user's designated water level.If the user has set water level and rinsing water level respectively, then different working stages uses different designated water levels.If the user has just set water level or rinsing water level separately, then to have set all process water levels identical for default user, and water level and rinsing water level are composed same user's setting value.If the user does not carry out water level settings and just begins washing, just at first judge the weight of washings in the washing machine, select suitable water level according to the weight of washings, simultaneously with rinsing water level assignment peak level, to realize optimum rinsing performance.
The operation principle that function is washed in transfiguration as shown in Figure 3, in the washing process that washing machine is started working, main control chip 2 detects actual water level by level sensor 6, if do not reach water level, then opens water intaking valve, begin water inlet, time-out is to the washing of washings, reaches the water level of setting until actual water level, then closes water intaking valve, stop into water, begin washing washings.Equally, in rinse cycle, the rinsing water level that actual water level need reach setting just can wash washings.
