The metal detecting device of clothes treatment device according to embodiments of the present invention is described 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 200 according to an embodiment of the invention can
Including pedestal 10, detection circuit 20, coil 30 and warning device 40.Alternatively, circuit board 210, detection can be provided with pedestal 10
Circuit 20 may be provided on circuit board 210.Thus, 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 can be produced when being powered, magnetic field covers at least a portion of pedestal 10 and prolonged with the thickness direction substantially along pedestal 10
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 is from metal detecting device 100
Top is moved, when making the cleavable magnetic line of force of metal object, and 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, be used as the driving current and driving voltage of warning device 40
Driving current driving warning device 40 is alarmed, and realizes the function of metallic foreign body identification.
Wherein, detection circuit 20 is preset with reference voltage value, the alertness level of warning device 40 with driving voltage voltage
Value and the difference of reference voltage value change.That is, when the magnitude of voltage of driving voltage and the difference of reference voltage value are different, reporting
The alertness level of alarm device 40 is also different.When different metal objects passes through metal detecting device 100, it can be produced in detection circuit 20
The magnitude of voltage of raw driving voltage is different, and the magnitude of voltage of the driving voltage is also different from the difference of reference voltage value, warning device
40 can send different degrees of alarm, so that the different alertness levels that different metal thing can be from different warning devices 40
Correspondence is realized, different metal objects can be distinguished by different alertness levels.
Because the different metal object of material can produce different influences to magnetic field, so that detection circuit 20 can be produced
Different driving voltages.Assuming that when coil 30 is connected in detection circuit 20, the preset magnetic induction intensity of coil 30 itself is B,
Can the magnitude of voltage U on the basis of electromagnetic conversion by detection circuit 20.For convenience of explanation, it is right by taking common silver, copper, nickel, iron as an example
The magnetic induction intensity answered respectively BS、BC、BN、BF, magnitude of voltage respectively U is obtained by the electromagnetic conversion of detection circuit 20S、UC、
UN、UF, calculate with the reference voltage value U of coil 30 difference △ (such as：△US=US-U).The metal of unlike material is to that should have not
Same voltage difference, forms different driving currents on warning device 40, then to that should have the alarm of different alertness levels, so as to
To identify the metal object of the unlike materials such as silver, copper, nickel, iron, with the whole mistake of this metal object identification for completing unlike material
Journey, recognition effect is good, and accuracy is higher.
Similarly, because the metal object of different volumes can produce different influences to magnetic field, so that detection circuit 20
Different driving voltages can be produced.Assuming that when coil 30 is connected in detection circuit 20, the preset magnetic induction of coil 30 itself
Intensity is B, can the magnitude of voltage U on the basis of electromagnetic conversion by detection circuit 20.For convenience of explanation, herein with common easy throwing
Exemplified by entering four kinds of metal objects in washing machine, for example：Drawing pin, coin, key, mobile phone, their volume is from small to large；It is corresponding
Magnetic induction intensity is respectively B1、B2、B3、B4, magnitude of voltage respectively U is obtained by what electromagnetic conversion was obtained1、U2、U3、U4, calculate with
The reference voltage value U of coil 30 difference △ is (such as：△U2=U2-U).The corresponding different voltage difference △ of the metal object of different volumes
U1、△U2、△U3、△U4, different driving currents are formed on warning device 40, then to that should have the alarm of different alertness levels,
So as to identify the metal object of different volumes, with the whole process of this metal object identification for completing different volumes, identification
Effect is good, and accuracy is higher.
Metal detecting device 100 according to embodiments of the present invention, by setting connected coil 30 and detection circuit 20 with
And the warning device 40 being connected with detection circuit 20, the automatic identification detection to metal object can be not only realized, without right manually
Clothing carries out checking whether there is metal object, and performance is good, and can realize the identification to different metal thing, recognition effect
Good, accuracy is higher.
The mode of the utilization cutting magnetic line configured on the metal detecting device 100 senses with traditional through type of coil 30
Compare, recognition accuracy is higher, recognition effect is good, the metal object for variety classes and different volumes etc. can effectively be known
, it is not flexible to operation, efficiently solve metal erroneous judgement problem.
In the present invention, can have a variety of for the alarm form that warning device 40 is presented, correspondingly, warning device 40
Alertness level can also have a variety of presentations.For example, warning device 40 can be alarm lamp or emergency alarm bell etc..When metal detection dress
When putting 100 and detecting metal object, alarm lamp can send luminous, and emergency alarm bell can be with sounding, and warning effect is directly perceived, it is easy to differentiate.
Wherein, in some specific examples of the present invention, warning device 40 is alarm lamp, and the bright dark degree of alarm lamp is with upper
State difference change.That is, the alertness level of alarm lamp can be embodied by the size of bright dark degree, for example, being on duty
When being worth larger, alarm lamp can send brighter light, and when difference is smaller, alarm lamp can send dark light.Thus, alarm is straight
The property seen is stronger, and distinguishing is good, and warning effect is good.Certainly, when warning device 40 is alarm lamp, alertness level can also be by it
Its form is embodied, for example, can be embodied by sending the light of different colours, or by send the light of different frequency come
Embody etc..
In other specific examples of the present invention, warning device 40 is emergency alarm bell, and the tone audio of emergency alarm bell is with above-mentioned
Difference changes.That is, the alertness level of emergency alarm bell can be embodied by the size of tone audio, for example, working as difference
When larger, emergency alarm bell sends the higher tone of audio, when difference is smaller, and emergency alarm bell sends the relatively low tone of audio.Thus, report
Alert intuitive is stronger, and distinguishing is good, and warning effect is good.Certainly, when warning device 40 is emergency alarm bell, alertness level can be with
Embodied by other forms, for example, can be embodied by sending the tone of different volumes.
