Abstract
The utility model relates to a device position detecting circuit which comprises a Hall sensor, a permanent magnet, and a Hall effect detecting circuit which is used for judging whether a Hall signal exists or not; the Hall effect detecting circuit comprises a single chip microcomputer; and the Hall sensor and the permanent magnet are arranged at least two classes of different devices. When a second-class device used for providing an additional function is arranged on a first-class device, the Hall sensor is close to the permanent magnet; owning to the Hall effect, the single chip microcomputer judges that the second-class device is arranged on the first-class device and/or the position of the second-class device according to change of the detected level; subsequently the single chip microcomputer carries out corresponding protection or function selection; simultaneously when the second-class device is separated from the first-class device, as the distance from the Hall sensor to the permanent magnet is further, the Hall effect disappears, the single chip microcomputer judges that the second-class device is separated from the first-class device according to the change of the detected level; and subsequently the single chip microcomputer carries out the corresponding protection and function selection. The utility model also relates to a device which comprises the device position detecting circuit.
Description
Technical field
The utility model relates to a kind of testing circuit, especially a kind of testing circuit that is used to detect the attachment device position that is installed on the main device; The utility model also relates to a kind of device that comprises foregoing circuit.
Background technology
Hall effect is a kind of of magnetic effect, this phenomenon is that U.S. physicist Hall was found when studying the conductive mechanism of metal in 1897, when current vertical in external magnetic field when the conductor, electric potential difference can appear between two end faces perpendicular to magnetic field and direction of current of conductor, this phenomenon is exactly a Hall effect, and this electric potential difference is exactly that Hall voltage is poor, at present, Hall effect is widely used in various industries, especially the motor speed measuring aspect.
On the existing home appliance; except the main device of realizing basic function; the general attachment device that is used to realize various additional functions that also is attached with; when attachment device being installed on the main device; main device need be judged whether this attachment device has been on its fuselage or to the position of attachment device and make judgement, and then make corresponding protection, function selecting or show the warning feedback.
The utility model content
It is a kind of when on the main device adhesion equipment being installed that the purpose of this utility model is to provide, and can detect the position of adhesion equipment, thereby protect or the setting position testing circuit of other function actions and include the device of this circuit.
In order to achieve the above object, the technical scheme that the utility model adopted is:
A kind of setting position testing circuit, comprise Hall element, permanent magnet and be used to judge whether exist the Hall effect testing circuit of hall signal, the Hall effect testing circuit comprises single-chip microcomputer, and Hall element, permanent magnet are installed on the different device of two classes at least.
Technique scheme can also be further perfect, and as preferably, Hall element is installed on the first kind device, and permanent magnet is installed on the second class device, and the second class device is the attachment device of first kind device.
Selectable, permanent magnet is installed on the first kind device, and Hall element is installed on the second class device, and the second class device is the attachment device of first kind device.
As preferably, the Hall effect testing circuit is arranged on the first kind device.
As preferably, single-chip microcomputer is the controller of first kind device.
As preferably, second installation site of class device on first kind device need be satisfied in the induction region that makes permanent magnet be in Hall element.When the Hall effect testing circuit detected Hall effect, single-chip microcomputer judged that the second class device is arranged on the first kind device.
As preferably, first kind device is a washing machine.
As preferably, the second class device is a ultrasound wave scrubbing pen.
When the second class device that additional function is provided is on the first kind equipment, Hall element is near permanent magnet, because Hall effect, single-chip microcomputer is made second kind equipment according to detected level variation and is positioned on the first kind equipment and/or the judgement of the second kind equipment position, then, make corresponding protection or function selecting; Same, after second kind equipment breaks away from first kind equipment, because the distance of Hall element and permanent magnet becomes far away; Hall effect disappears, and single-chip microcomputer changes according to detected level, makes the judgement that second kind equipment has broken away from first kind equipment; then, make corresponding protection and function selecting.
A kind of device comprises the said apparatus position detecting circuit.
Because the employing of technique scheme the utlity model has following advantage:
The utility model is on the basis that existing home appliance basic function realizes, for the increase of additional functional device provides a kind of new mentality of designing, this circuit is simple and practical, and is with low cost, has the wide application and the market space.
