Describe the metal detecting device of clothes treatment device according to embodiments of the present invention in detail with reference to Fig. 1 and Fig. 2
100。
Shown in reference picture 1, the metal detecting device 100 of clothes treatment device according to an embodiment of the invention may include
Pedestal 10, detection circuit 20, coil 30, warning device 40 and adjustment module 50.Alternatively, circuit board can be provided with pedestal 10
210, detection circuit 20 may be provided on circuit board 210.Thus, it is more convenient to be manufactured and installed, functional reliability is higher.
Detection circuit 20 is located on pedestal 10, and coil 30 is located on pedestal 10 and is connected with detection circuit 20.Coil 30
Magnetic field, magnetic field can be produced to cover at least a portion of pedestal 10 and prolong with the thickness direction substantially along pedestal 10 when being powered
The magnetic line of force stretched.Here, covering pedestal 10 in magnetic field can be interpreted broadly, for example, it can be understood as pedestal 10 is located in magnetic field,
The magnetic line of force in magnetic field can pass through pedestal 10.
Warning device 40 is connected with detection circuit 20, and detection circuit 20 can produce driving electricity in metal object cutting magnetic line
Stream, driving current can drive warning device 40 to work.Thus, when the clothing with metal object from metal detecting device 100
Top is moved, and when making the cleavable magnetic line of force of metal object, the magnetic field that coil 30 is produced can change, and become magnetic induction intensity
Change, detection circuit 20 can detect the change, and produce corresponding induced voltage, and then produce corresponding induced electricity
Stream, the induced-current and induced voltage can transport to warning device 40, used as the driving current and driving voltage of warning device 40
Driving current drives warning device 40 to alarm, and realizes the function of metallic foreign body identification.
Wherein, detection circuit 20 is preset with reference voltage value, when the magnitude of voltage of driving voltage is more than reference voltage value, drives
Dynamic voltage can drive warning device 40 to work.Adjustment module 50 is connected with detection circuit 20, and can change reference voltage
Value.Thus, it is possible to realize the regulation of metal detection sensitivity.
Specifically, coil 30 is connected in detection circuit 20, and the preset magnetic induction intensity of coil 30 itself is B, can be passed through
Detection circuit 20 carries out electromagnetic conversion into reference voltage value U；Adjustment module 50 is provided with multi gear, for example, third gear：1 grade, 2 grades, 3 grades,
Acquiescence is at 1 grade (sensitivity minimization)；The gear of the preset magnetic induction intensity of coil 30 itself is provided with by detection circuit 20, point
Wei not B1、B2、B3, corresponding reference voltage value is respectively U1、U2、U3, and U1＞ U2＞ U3。
For convenience of explanation, as a example by detecting one circle coin.When one piece of coin passes through coil 30, the magnitude of voltage for obtaining is
UK, the voltage difference △ U=U for calculatingK-U1If △ U ＜ 0 cannot drive warning device 40, one piece of coin then to detect
Go out；Sensitivity is adjusted to 2 grades, the voltage difference △ U=U for drawingK-U2If △ U ＞ 0 can detect one piece of coin.Separately
On the one hand, when adjustment of sensitivity is arranged on 1 grade, due to UK＜ U1, it is impossible to detect one piece of coin；It is same using two pieces of coins
When by coil 30, the magnitude of voltage for obtaining is UK2, voltage difference △ U=UK2-U1If △ U ＞ 0 can detect this two pieces
Coin.
As can be seen here, when sensitivity change is big, one piece of Detecting of coin that script can not be detected can be gone out, and same
Under one sensitivity, coin is more, and Detection results are better.
Metal detecting device 100 according to embodiments of the present invention, by set connected coil 30 and detection circuit 20 with
And the warning device 40 that is connected with detection circuit 20 and adjustment module 50, can not only realize the automatic identification inspection to metal object
Survey, clothing is carried out without manually check whether there is metal object, performance is good, and can realize the tune of detection sensitivity
Section, can flexibly set different detection sensitivities according to different requirements in actual use, use flexible, Detection results
It is good.
The mode of the utilization cutting magnetic line configured on the metal detecting device 100 senses phase with traditional coil through type
Than recognition accuracy is higher, and recognition effect is good, by adjusting means the sensitivity of identification can be made adjusted, easy to operate
Flexibly, metal erroneous judgement problem is efficiently solved.
In the present invention, do not do specifically limited for the concrete structure of adjustment module 50, adjustment module 50 can be regulation
Knob, touch key-press or touch-screen etc., this can be for a person skilled in the art to understand and easily realize, herein
It is not described in detail.
In some embodiments of the invention, reference voltage value can consecutive variations within a predetermined range.Thus, it is possible to realize
Sensitivity is continuously adjusted.In other embodiments of the invention, reference voltage value can change between multiple predetermined values.By
This, each sensitivity can correspond to a range of metal object, adjust apparent, and modulability is good.Here, preset range and pre-
Definite value can be configured according to actual conditions, and the present invention is not particularly limited to this.
