The specific embodiment
Washing machine 1 of the present invention is horizontal axis washing machine 1, wherein the in the situation that of unbalanced load, is assigned to constantly the position of expectation in order to the quantitative water that compensates unbalanced load and minimize this effect, and this washing machine comprises: body 2; Be placed in body 2 cylinder inner and that rotate along horizontal axis, article to be washed are placed in this cylinder; And the staving 3 that rotates therein of cylinder.
Washing machine 1 further comprises:
At least one block 7, its made by conductibility, flexible material and staving 3 placed on it;
Two conductibility plates 8, it is placed in block 7 inner sides conductive of material is remained on therebetween, wherein forms potential difference by applying electric current to it; And
Weight sensor 9, its change measurement according to the capacitance between plate 8 acts on the weight in block 7, aforementioned electric capacitance about between plate 8, acted on the distance that the weight in block 7 affects and changed.
Therefore, block 7 not only provides the maintenance to staving 3 but also the carried generation damping of vibration to staving 3 and determining of weight to the load being applied to it.
Be embedded at two tabular conductibility plates 8 during production block 7 that block 7 inside make to maintain betwixt conductive of material and conductive material remains between two conductibility plates 8 with specific dielectric constant, make block 7 as like " plate condenser " the same (Fig. 3).Be embedded in block 7 plate 8 interior and active electrode and be electrically connected to weight sensor 9.In this embodiment, in the time of a ground connection in plate 8, another of plate 8 is connected to weight sensor 9, makes to form potential difference (Fig. 4) between two plates 8.
These plates 8 that are arranged on block 7 inside move towards one another or move apart, and are proportional to block 7 due to its flexibility, by being placed in the weight of the staving 3 in block 7 and/or compression or the expansion that unbalanced load produces.The value of the capacitance of block 7 because of the change of the distance between the plate 8 of block 7 inside and due to the movement of staving 3 and thereby the unbalanced load that produces change.The change of the value of output signal (Vout) frequency based on capacitance of weight sensor 9 and changing, and determine thus the weight of staving 3 and the amount of unbalanced load.
In the time that load is in block 7, block 7 pressurizeds and plate 8 shift near mutually.Shift near effect due to this, the value of the capacitance of block 7 increases, and the output signal of weight sensor 9 (Vout) frequency reduces.In the time acting on load in block 7 and be removed, block 7 open and plate 8 from moving apart each other.In this state, output signal (Vout) frequency of the reduction of the value of the capacitance of block 7 and weight sensor 9 increases.
In embodiments of the present invention, block 7 is by making based on polymeric material.
In another embodiment of the present invention, block 7 is made up of elastomeric material.
In another embodiment of the invention, plate 8 is made up of the metal material with high conductance that resembling aluminium or copper.
In an embodiment more of the present invention, plate 8 is made by having conductive polymer material.Therefore, plate 8 is provided to move towards one another or move apart to compression and the more proportional mode of expansion of block 7.In addition also protected, the flexibility of block 7.
In an also embodiment of the present invention, be preferably the support member 6 of being made by metal material and be fastened to the below of block 7 and top to increase the intensity of block 7.These support members 6 have not only increased the intensity of block 7 but also the uniform damping of the load being applied to it are provided.
In another embodiment of the present invention, washing machine 1 comprises: keeper 4, it is fastened on the surface of two body 2 sidewalls of staving 3, and along the length of aforementioned lateral wall, be parallel to the cylinder axis extending along horizontal axis; And be anchored on the static element 5 of staving 3, its sidewall from staving 3 surfaces towards body 2 extends, make its by with keeper 4 in identical vertical non-alignment.In this embodiment, block 7 is placed between keeper 4 and static element 5, and is fastened to keeper 4 from below, is fastened to static element 5(Fig. 1 and Fig. 2 from top).The whole load of staving 3 is dispensed to block 7 by the static element 5 that is fastened to staving 3.
By means of the present invention, not using in the washing machine of damper/spring system, the vibration of staving 3 that not only maintained staving 3 and damping, but also determined load by block 7.Therefore, also detect Static and dynamic load, prevented the detection loss that damper/spring system faces.
Should understand, the present invention is not limited to disclosed embodiment above, and those skilled in the art can easily draw different embodiments.These different embodiments also should be considered to drop in the scope of claim of the present invention.
