Abstract
The present invention relates to washer and its control method. The washer has pollution sensor set inside the washing barrel in the water level to detect the pollution degree of the washing water. The pollution sensor transmits the pulse signal the pulse generator generates to make the microcomputer regulate the rinsing times based on the pollution degree of the washing water. Even if rinsing number is set by the user, the washer microcomputer will regulate the rinsing times automatically based on the conductance of the washing water and the output current and voltage affected by the washing water and the detected pollution degree of the washing water. The present invention can avoid waste in washing water and electric power and raise washing efficiency of the washer.
Description
Technical field
The invention relates to washing machine itself and control method, specifically be meant pollution level, in washing process, regulate the washing machine and the control method thereof of rinsing number of times automatically according to washings and washings.
Background technology
Along with the increase of women's housework, washing machine has spread to any one family.Therefore, washing machine manufacturer is just for producing the constantly effort of washing machine that meets consumer wants, and particularly being devoted to develop can increase user's comfort level, can give play to the washing machine of maximal efficiency again.Now developed the washing machine of multiple washing process, the washing machine that has only needs the user to handle a button simply just can oneself select the washing process of needs, and the washing machine that also has detected washing weight of foundation in washing process waits regulates washing process.
But, being provided with in the washing machine of prior art of above-mentioned various functions, the user can directly select to float the number of times of washing.In this case, do not consider the clean level of washings such as the scourability of washing machine and lining, certain rinsing time and rinsing number of times just are set, rinse action can not be brought into play effectively.Because the user do not consider the pollution level of washings the rinsing number of times just is set, cause the with serious pollution washings rinsing result can not be satisfactory, have to from new execution rinse cycle.But, if, can produce the waste problem of electric energy and water just the rinsing number of times too much is set from beginning.
Summary of the invention
The present invention who produces as solving the existing above-mentioned technical problem of washing machine, its objective is, pollution level by washings in the perception washing process is provided, determines whether increasing or reducing the rinsing number of times, with automatic washing machine and the control method thereof that only wash conditions is set.
Washing machine involved in the present invention comprises as the lower part: place the washtub of washings, be arranged on washtub and contain on the position of washings, be used for detecting the contaminant sensor of washings pollution level; Impulse generator by contaminant sensor input pulse ripple signal; Transmit the sensor circuit of the pulse wave signal of impulse generator output by contaminant sensor; Utilize the impulse wave voltage of sensor circuit, detect the pollution level of washings, and regulate the microcomputer of rinsing number of times according to the pollution level of washings.
Control method for washing machine of the present invention comprises following four-stage: contain the phase I that the contaminant sensor at washings position detects the washings pollution level by being positioned at washtub; Utilize the second stage of contaminant sensor transmission current; The phase III that transmission current is exported according to the pollution level of washings; Quadravalence section according to the voltage-regulation rinsing number of times of output current.
Washing machine of the present invention and control method thereof, even make the user set the rinsing number of times of washings, the microcomputer of washing machine is in rinse cycle, lead voltage with the output current of its influence etc. by the electricity of washings, detect the pollution level of washings, the moving rinsing number of times of regulating prevents that the user from causing the waste of electric energy and water when mistake is provided with the rinsing number of times, help improving detersive efficiency.

The specific embodiment
Now illustrated with regard to the specific embodiment of the present invention in conjunction with the accompanying drawings.
As shown in Figure 1, washing machine involved in the present invention is by constituting as the lower part: the contaminant sensor 10 of the detection washings pollution level that the position of Sheng washings is provided with in the washtub of placing washings; Utilize the impulse generator 20 of contaminant sensor 10 output impulse waves; By polluting the sensor circuit 30 that inductor 10 transmits impulse generator output pulse wave signal; Perception detects the pollution level of washings by the pulse voltage of sensor circuit, and regulates the microcomputer 40 of rinsing number of times according to the pollution level of washings.
Sensor circuit 30 is by the transformer 31 that is connected with contaminant sensor 10, constitute by the current delivery circuit 32 of transformer 31 to microcomputer 40 transmission currents.
Transformer 31 is connected with contaminant sensor 10, according to the washings pollution level output current of contaminant sensor 10 detections.Promptly contaminant sensor 10 is placed in washings where, is used for detecting the degree of removing contamination of washings and the residual concentration of washing agent.The residual concentration of washing agent is high more, and the magnitude of current of transformer 31 outputs is just big more.
Along with the increasing of the magnitude of current of transformer 31 output, will step-down by current delivery circuit 32 to the current/voltage of microcomputer 40 inputs.Microcomputer 40 detects the current/voltage of input, and judges the pollution level of washings according to voltage, appends or reduce the rinsing number of times of washings.
As shown in Figure 1, the current delivery circuit is by constituting as the lower part: make transistor Q1 that electric current in the transformer increases and the capacitor C 402, the resistance R 403 that are connected separately with transistor Q1 and semiconductor transistor SD400 and the SD401 that is connected with capacitor C 402, and capacitor C 403 and with itself and the resistance C404 that connects.
Shown in the graph of a relation between the detected current/voltage of Fig. 2 microcomputer and the washings pollution level-washing agent residual concentration judged according to this, when the current voltage that detects when microcomputer reached the 5V left and right sides, microcomputer was just made the low judgement of washing agent residual concentration; When detected voltage was about 0, microcomputer was just made the high judgement of washing agent residual concentration.
Shown in Fig. 3 control method programme diagram involved in the present invention, in the carrying out of washing process S1, microcomputer 40 will judge whether the S2 washing process finishes at once.As judge that washing process can not finish, and will enter the S3 process, proceed washing.
Before judging that the S2 washing process finishes, microcomputer with the voltage value that perception transmits by current delivery circuit 32, enters the S4 process for the residual concentration of the pollution level-washing agent of detection washings.
Microcomputer 40 confirms whether the voltage value that perceives is under reference voltage in the S4 process, i.e. the S5 process.
If the voltage that microcomputer perceives is under reference voltage the time, microcomputer will stop rinse cycle, carry out next process, i.e. drainage procedure S6.
If in the S5 process, the voltage value that microcomputer perceives is not under reference voltage the time, enters the S7 process, and microcomputer will increase the rinsing number of times, carry out rinsing.After executing the rinse cycle that appends, enter the S6 process again.
