Abstract
The invention discloses a kind of systems that detection roller washing machine hangs spring-drop, including acceleration transducer, control mainboard and alarm.The present invention proposes a kind of method that detection roller washing machine hangs spring-drop, acceleration transducer can monitor the acceleration on three directions when washing machine drum rotation, and form acceleration wave moving curve, when the frequency of curve is more than or equal to 6Hz, control mainboard, which starts alarm and controls washing machine, to be stopped.Detection method proposed by the present invention can find that failure, accuracy rate effectively increase working efficiency 95% or more in time, reduce dangerous caused by due to mechanical disorder.
Description
Technical field
The present invention relates to system and sides that spring-drop is hung in washing machine technology field more particularly to a kind of detection roller washing machine
Method.
Background technology
During roller washing machine use, there is a phenomenon where hang spring-drop for occasional for various reasons.Hang spring-drop
Phenomenon refer to washing machine hang spring hook fall off from babinet or the card slot of outer barrel so that washing machine drum cannot keep suspension status
And the phenomenon that falling.After hanging spring-drop, if machine fails to detect and continue to run with, it is possible to the damage of machine itself can be caused
It is bad possibly even to cause the bounce of entire washing machine or movement that other finance damages is caused even to jeopardize user security.
Invention content
Technical problems based on background technology, the present invention propose it is a kind of detection roller washing machine hang spring-drop be
System, acceleration transducer is installed on the roller of washing machine, judges to hang whether spring falls off according to the variation of the frequency of acceleration.
A kind of system that detection roller washing machine hangs spring-drop, including acceleration transducer, control mainboard and alarm, add
Acceleration information when velocity sensor rotates washing machine drum is transmitted to control mainboard；When acceleration information is more than preset
When numerical value, control mainboard starts alarm and is simultaneously stopped washing machine drum rotation.
A method of detection roller washing machine hangs spring-drop, and the acceleration transducer can detect washing machine drum 3
Acceleration on direction, 3 directions include：The acceleration value y and upper and lower directions of acceleration value x in the front-back direction, left and right directions
Acceleration value z.
Preferably, the acceleration transducer every 5 milliseconds to control mainboard transmission primaries signal.
Preferably, the acceleration wave moving curve on 3 directions is formed by x, y, z numerical value, when any one acceleration fluctuates
When frequency >=6Hz of curve, washing machine starts alarm and is stopped.
A kind of roller washing machine of system for hanging spring-drop comprising detection roller washing machine proposed by the present invention.
Further, acceleration sensor is arranged in the lower surface of washing machine drum bottom plate.
Beneficial effects of the present invention：
The present invention proposes a kind of system and method that detection roller washing machine hangs spring-drop, which includes acceleration sensing
Device, control mainboard and alarm, acceleration transducer can monitor the acceleration on three directions when washing machine drum rotation, and
Acceleration wave moving curve is formed, when the frequency of curve is more than or equal to 6Hz, control mainboard starts alarm and controls washing machine and stops
Only work.Detection method proposed by the present invention can find that failure, accuracy rate effectively increase work 95% or more in time
Efficiency reduces dangerous caused by due to mechanical disorder.
Description of the drawings
Attached drawing is used to provide further understanding of the present invention, and a part for constitution instruction, the reality with the present invention
It applies example to be used to explain the present invention together, not be construed as limiting the invention.In the accompanying drawings：
Fig. 1 is the acceleration change curve in 3 directions in embodiment 2；
Fig. 2 is the frequency of the acceleration in 3 directions in embodiment 2.
Wherein：1- acceleration wave moving curves in the front-back direction, the acceleration value curve of cyclical fluctuations of 2- left and right directions, 3- upper and lowers
To the acceleration value curve of cyclical fluctuations, 4- unusual fluctuations starting points.
Specific implementation mode
The present invention is made further to explain with reference to specific embodiment.
Embodiment 1
A kind of system that detection roller washing machine hangs spring-drop, including acceleration transducer, control mainboard and alarm, add
Acceleration information when velocity sensor rotates washing machine drum is transmitted to control mainboard；When acceleration information is more than preset
When numerical value, control mainboard starts alarm and is simultaneously stopped washing machine drum rotation.
A method of detection roller washing machine hangs spring-drop, and acceleration transducer can detect 3 directions of washing machine drum
On acceleration, 3 directions include：Acceleration value x, the acceleration value y of left and right directions and adding for upper and lower directions in the front-back direction
Velocity amplitude z.Acceleration transducer is every 5ms to control mainboard transmission primaries signal.It is formed on 3 directions by x, y, z numerical value
Acceleration wave moving curve, as frequency >=6Hz of any one acceleration wave moving curve, washing machine starts alarm and stops work
Make.
Embodiment 2
Rubber block fictitious load experiment is carried out to monitoring system proposed by the present invention, the sensor brand used is that writing brush is general
HP-TRS01, experiment condition are：Total load：12.92kg, uniform load 10.32kg, eccentric load 2.6kg.
When washing machine drum roller reduction of speed, about 240rpm occurs hanging spring-drop phenomenon.
By the acceleration change curve of Fig. 1 it is found that in 1070ms, the acceleration of washing machine drum is in three sides of x, y, z
Occurs abnormal fluctuation upwards.
As shown in Figure 2, before unusual fluctuations, before there is exception, the frequency of wave exists the acceleration in three directions of x, y, z
6Hz is hereinafter, and keep more stable variation；After there are unusual fluctuations, the vibration frequency of the acceleration in three directions of x, y, z
More than 6Hz, detect washing machine drum at this time hangs spring-drop.
It should be noted that：Spring is hung at the time of falling off, it may be possible to which the acceleration wherein on some direction first occurs
The acceleration of the variation of vibration frequency, other two direction then changes again, therefore what is shown in fig. 1 and 2 is
The exception of acceleration on three directions；But have alarm as long as there is exception there are one the acceleration in direction.
The foregoing is only a preferred embodiment of the present invention, but scope of protection of the present invention is not limited thereto,
Any one skilled in the art in the technical scope disclosed by the present invention, according to the technique and scheme of the present invention and its
Inventive concept is subject to equivalent substitution or change, should be covered by the protection scope of the present invention.
