Technical scheme in the present invention is understood better in order to make those skilled in the art person, below in conjunction with the accompanying drawing in the embodiment of the present invention, technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, should belong to the scope of protection of the invention.
A kind of washing machine foot sensory perceptual system of the present invention, comprising:
Be positioned at the pressure sensor below the some footing of washing machine;
Be positioned at the stepper motor above the some footing of washing machine;
The control unit be connected with stepper motor with pressure sensor.
Ginseng Figure 1 shows that washing machine foot mounting structure schematic diagram in the present invention.Footing 1 is identical with the bottom stud structure of conventional laundry apparatus, is provided with pressure sensor 2 at the bottom center position of footing 1, for the force value on Real-time Collection footing 1.Be fixed with case shell (not shown) above footing 1, it is inner that stepper motor 3 is fixedly installed in case shell, and the motor shaft of stepper motor 3 is fixedly connected with footing 1, and then realizes the synchronous axial system of motor shaft and footing.
Shown in ginseng Fig. 2, footing 1 comprises connecting portion 11, holding section 12 and support portion 13, connecting portion 11 comprises arc sections 111 and planar portions 112, and the motor shaft of stepper motor can be fixed in the receiving space of arc sections 111 and planar portions 112 formation by attaching parts, and then drives the rotation of footing.Holding section 12 is provided with screw thread, and during rotation, footing 1 can realize rising or declining by screw thread.Preferably, the connecting portion 11 on footing 1, holding section 12 and support portion 13 are formed in one structure.
The motor shaft of stepper motor 3 is connected by a junction with footing 1, footing 1 can be driven to rotate adjust footing height when stepper motor 3 rotates.
Control unit (MCU) is located at washing machine internal, is provided with footing awareness program in control unit, for calculating footing perception value and judging perception value whether within preset range, simultaneously also for control step motor adjustment washing machine foot height.Also comprise control panel in control unit, user can control the operation of described washing machine foot sensory perceptual system as required.Footing awareness program can the isolated operation independent of standardization program, only carries out adjustment footing; Washing machine works under standardization program, also can carry out footing awareness program.
The footing 1 that in the present invention, washing machine at least two is adjacent is provided with pressure sensor 2 and stepper motor 3, preferably, arranges pressure sensor 2 and stepper motor 3 in the present embodiment by adjacent for washing machine front two footing 1.
Ginseng Figure 3 shows that the schematic flow sheet of washing machine foot cognitive method of the present invention, and it comprises the following steps:
Force value on S1, the some footing of Real-time Collection washing machine.Wherein, " some footing " at least comprises two adjacent footing, preferably, is adjacent two footing in washing machine front in the present embodiment;
S2, calculate footing perception value according to force value that footing collects.Inner cylinder rotating one encloses each footing and gathers to obtain one group of force value data, obtain the difference of the maximum of these group force value data, minimum of a value, mean value and maxima and minima, the difference according to maximum, minimum of a value, mean value and maxima and minima tries to achieve perception value;
S3, judge perception value whether within preset range, if so, terminate footing perception, if not, perform step S4;
S4, control electric machine rotation according to perception value, adjustment washing machine foot height, until footing perception value is within preset range.
Further, in the present invention one preferred embodiment, step S2 also comprises:
Inner cylinder rotating one circle obtains a perception value, circulation several times, obtains several perception value and is averaged as a perception value.
In a specific embodiment of the present invention, when carrying out footing adjustment, first in laundry machine barrel, be placed with certain eccentric load, under footing adjustment programme pattern, washing machine is started working, when reaching certain rotating speed (for the general 100RPM of roller washing machine), start to carry out footing perception.
Control unit (MCU) constantly gathers the pressure value signal of pressure sensor feedback and is stored in an array, inner cylinder rotating one encloses the data gathered and calculates one group of data, get its maximum, minimum of a value, mean value the difference of maximizing and minimum of a value, comprehensively these parameters obtain perception value.
Circulate four times according to this, try to achieve four perception value and be averaged as a perception value.
Circulation carry out footing perception and control motor positive and inverse adjustment footing, until inner core pass on maximum speed and footing perception value within systemic presupposition scope time, footing perception terminates.
Whether the quality no matter footing adjusts, footing more or less has the vibration of above-below direction, adjacent two footing upward pressure sensor feedback signals just have certain fluctuation, and footing perception is exactly that maximum, minimum of a value, mean value and maxima and minima difference according to this fluctuation signal is determined.When footing is adjusted, washing machine four footing are stressed relatively more even, and the feedback signal of two pressure sensors is also relatively more steady, and the difference comparsion of the maxima and minima of pressure sensor feedback signal is little.When footing is not adjusted, when inner tank of washing machine has certain eccentric load and reaches certain rotating speed, certainly pair of horns footing is had to have larger vibration in four footing, the pressure sensor feedback signal fluctuation of corresponding footing can be larger, feedback signal minimum of a value is close to 0, maximum can than much larger time steady, and the difference of the maxima and minima of feedback signal will be very large.
Whether washing machine carries out footing perception in standardization program can be selected, if select to carry out footing perception, as long as add corresponding program; Select not carry out footing perception in standardization program after washing machine is laid, then first run a footing perceptual model program, namely carried out once automatically adjusting footing.
Washing machine foot cognitive method in the present invention and system can be applicable to roller washing machine or rotary drum washing machine.
Can be seen by above technical scheme, the washing machine foot cognitive method that the embodiment of the present invention provides and the quality that system is adjusted by footing perception reflection footing, the quality that footing is adjusted can quantize; Vibrating noise when complete machine works is reduced by the laundry function after footing cognitive method and system call interception; This washing machine foot cognitive method and system do not need user manually to adjust footing, and hommization more, intellectuality, be user-friendly to.
To those skilled in the art, obviously the invention is not restricted to the details of above-mentioned one exemplary embodiment, and when not deviating from spirit of the present invention or essential characteristic, the present invention can be realized in other specific forms.Therefore, no matter from which point, all should embodiment be regarded as exemplary, and be nonrestrictive, scope of the present invention is limited by claims instead of above-mentioned explanation, and all changes be therefore intended in the implication of the equivalency by dropping on claim and scope are included in the present invention.Any Reference numeral in claim should be considered as the claim involved by limiting.
