Background technology
Traditional washing machine structure comprises: cabinet; Be installed in the outer bucket and the washing tube of cabinet inside, the inner holding washing water of outer bucket, the central authorities of washing tube bottom are provided with the stirrer that can rotate, it can do rotatablely moving with respect to washing tube, form current, a following side of outer bucket is installed drive motor, for washing tube and stirrer provide driving power.In addition, clutch apparatus is installed below the outer bucket, is used for to washing tube and washing stirr transmission or blocks the power of drive motor.The core texture of this kind clutch coupling speed measuring device is that the brake band of bipitch structure is installed on the brake arm, double end is moved simultaneously and is realized the two-way of braked wheel held tightly, because of it adopts the counter electromotive force of motor proving installation, be subjected to input voltage, electromagnetic field effects bigger, precision was low when low speed was measured.Therefore, it is just necessary to invent a kind of new clutch coupling of washing machine velocity-measuring system.
The utility model content
In order to overcome the deficiencies in the prior art, the purpose of this utility model is to provide a kind of stable, sensitive clutch coupling proving installation, improves the precision of clutch coupling speed measuring device.
The utility model is achieved through the following technical solutions: the clutch coupling of washing machine speed measuring device, it is characterized in that comprising: annular magnetic steel, annular magnetic steel support, Hall element, Hall element support, wherein annular magnetic steel is installed in the end face of clutch belt dish by register pin, the trip bolt of annular magnetic steel support, the clutch belt dish is installed on the clutch shaft, and annular magnetic steel and annular magnetic steel support are formed the magnet steel assembly; Hall element is fixed on the clutch housing inner side end by the register pin and the trip bolt of Hall element support, and Hall element and annular magnetic steel surface minimum distance are no more than 5mm, and Hall element and sensor stand are formed hall sensor component.
Aforementioned clutch coupling of washing machine speed measuring device is characterized in that annular magnetic steel is an injection moulding magnet material, and magnetic pole evenly is arranged in annular outer surface, magnetic flux radially, the adjacent pole inequality is more than the 150GS apart from the magnet ring radial surface apart from the magnetic density at 5mm place.
Principle of work of the present utility model is: annular magnetic steel rotates with clutch shaft, when each magnetic pole of magnet steel in succession by Hall element on during dummy section, Hall element is back and forth carried out the open and close action, represents the velocity of rotation of clutch coupling by the switch number of times of Hall element in the record unit time.When the suffered damping of clutch coupling of washing machine clutch shaft changed, the clutch shaft rotating speed changed thereupon, thereby changed the switch number of times of Hall element.
The beneficial effects of the utility model are: the utility model clutch coupling of washing machine proving installation stable operation, sensitivity, improve the precision that tests the speed.
