The specific embodiment
Below in conjunction with the drawings and specific embodiments the present invention is described in further detail:
Fig. 2 is the structured flowchart of the levelness detecting device of washing machine of the present invention; Fig. 3 is the structured flowchart that the display screen shown in Fig. 2 constitutes.As shown in Figures 2 and 3, the levelness detecting device of washing machine of the present invention comprises: microprocessor 10 and controller 1; Described microprocessor 10 comprises: motor controlling processor 110 and levelness measurement processor 100; Described motor controlling processor 110 is used for controlling motor, and motor is used for driving the cylinder or the interior bucket rotation of washing machine; Described controller 1 comprises: electromotor control circuit 11, accelerometer 14, display screen 12 and alarm song generator 13; If described alarm song generator 13 just can produce alarm song during levelness overshoot scope automatically and remind the user in the use of washing machine; Described electromotor control circuit processor 11 receives after the signal of motor controlling processor 110, controls the duty of motor 2 according to the indication of signal; Described accelerometer 14 can detect dynamic acceleration and static acceleration simultaneously; Described display screen 12 comprises: display screen 120 is set in washing, display screen 121 and levelness display screen 125 are set in oven dry; The levelness that can show the washing machine that detects by accelerometer on the described levelness display screen 125 is observed for the user.
Described accelerometer 14 is a MEMSIC type accelerometer (a kind of sensor by the exploitation of MEMEIC company).
Described accelerometer 14 is actually a kind of semiconductor transducer, its operation principle is: can rise to the top after the air that semiconductor contains is heated, when washing machine produces or vibrations take place, the accessible part of air will change, at this moment, the free charge amount that is applied to sensor internal also can arrive the variation of part and changes along with air.Size according to gradient or shock momentum, corresponding variation can take place in the free charge amount that is applied to sensor internal, so just can detect the gradient or the shock momentum of washing machine by the method that detects its free charge amount, detect the levelness of washing machine indirectly.
Described alarm song generator 13 can an above buzzer or a quarter-bell.
The course of work to the levelness detecting device of washing machine of the present invention is illustrated below:
In the process of washing machine was set, the user was no longer only with the levelness of feeling to regulate washing machine, but the data shown according to levelness display screen 125, the levelness of coming to regulate scientifically, exactly washing machine.
In the process of washing machine is set, when under the state of controller 1 connection power supply, adjusting levelness, the levelness that accelerometer 14 detects is presented on the display screen 12, and the user is a foundation with the data that show, and can adjust the levelness of washing machine easily.
It is worthy of note, described accelerometer 14 is an accelerometer that can detect dynamic acceleration and static acceleration simultaneously, like this, in the setting up procedure of washing machine, utilize accelerometer 14 to detect static acceleration, and the result of static acceleration is expressed as numerical value or mark on levelness display screen 125, make the user carry out the adjusting operation of level of washing machine degree more easily.
At this moment, after the signal that levelness processor 100 degree of the will speed up meters 14 of described microprocessor 10 detect was handled, the levelness of washing machine just was converted into data signal output.
In addition, the numerical value that shows by levelness display screen 125 must be compared with the numerical value of degree of being up to the standard, thereby determines that washing machine needs left and right adjusting to regulate before and after still.If the levelness of washing machine represents by pointer and dial, the scale of the pointed in the time of also must be with degree of being up to the standard is compared, thereby determines that washing machine needs left and right adjusting to regulate before and after still.
In addition, after the setting of finishing washing machine, in use the levelness of washing machine also can change sometimes.In this case, the variation of levelness can detect by degree of being accelerated meter 14, and is presented on the display screen 12 of controller 1.
In addition, in the use of washing machine, because the influence of external factor such as vibrations, the levelness of washing machine changes, and during the allowed band of overshoot, accelerometer 14 can detect the deviation of levelness, and be presented on the display screen 125 in the mode of data signal, meanwhile, the alarm song generator can sound the alarm, and automatically prompting user is noted.
At this moment, the user utilizes accelerometer 14 once more, utilizes method identical when washing machine is set, and the levelness of regulating washing machine once more continues to use washing machine then.
Those of ordinary skill in the art it is worthy of note that protection scope of the present invention does not limit the above-mentioned specific embodiment, because according to basic fundamental design of the present invention, can associate other various embodiments easily.
The present invention not only is applicable to tumbling-box washing machine, also is applicable to pulsator washing machine, also is applicable to other household electrical appliance that other need the detection level degree.
