Abstract
A kind of laundry machine, include housing, control device, the vibration component being suspended in by damping device in housing, wherein vibration component includes outer barrel, loaded on the interior bucket in outer barrel, the motor being fixedly connected with outer barrel and is connected motor and the driving belt of interior bucket, vibration component includes the sensor of the vibration signal of detection vibration component, vibration signal of the control device according to measured by sensor judges whether motor belt fails in program operation process, so as to make counter-measure in time, avoid damaging clothing and machine.
Description
【Technical field】
The present invention relates to a kind of household electrical appliance for being washed and/or being dried to clothing, more particularly to household electrical appliance electricity
The detection whether machine belt fails.
【Background technology】
Washing machine, dryer or clothes washer-dryer generally have the interior bucket for being driven and being rotated by motor.Interior bucket and motor it
Between connected by belt, play a part of transmission.Have after washing machine long-term use, during motor belt and come off or aging fracture
Phenomenon.Now, interior bucket can not be driven, thus be stopped operating.And if washing machine control program can not identify the failure of belt,
This exception of user thus can not be reminded in time, can not also make corresponding protection and adjustment, but according to selected program after
Continuous work.Then motor continues to dally, and interior bucket is static, has both consumed the energy, can not clean clothing again.Dried if machine is in
In the dry stage, because interior bucket is static, high temperature air Long Term Contact clothing surface, it will then cause the damage of clothing.
【The content of the invention】
An object of the present invention is to enable laundry machine to find the failure of motor belt in time automatically, and makes phase
Answer measure.
For object above, the technical solution adopted by the present invention is：A kind of laundry machine, comprising housing, control device,
The vibration component being suspended in by damping device in housing, wherein vibration component include outer barrel, loaded on the interior bucket in outer barrel, with it is outer
The motor and connection motor and the driving belt of interior bucket that bucket is fixedly connected, vibration component include the vibration of detection vibration component
The sensor of signal, control device are so arranged to judge whether motor belt fails in program operation process：Washing
And/or in drying procedure running, the vibration signal of sensor detection vibration component simultaneously sends this signal to control device, controls
Device processed determines motor rotation status simultaneously, if motor is in rotation status, control device when the vibration signal measured is zero
Judge that driving belt fails.In normal operation, motor driven interior bucket turn.Due to laod unbalance power and rotatory inertia
Effect, interior bucket drives whole vibration component to vibrate.Sensor can then obtain vibration signal.And work as driving belt
When coming off or the failure conditions such as being broken, even if motor still in rotation status, drive of the interior bucket due to losing belt, will tend to
Static, also therefore reduction is simultaneously final static for the vibration of vibration component.Therefore the vibration signal that sensor is caught will diminish, until most
After can't detect vibration signal.Therefore, the vibration signal of vibration component can determine whether to pass when being worked by detecting laundry machine
Whether dynamic belt fails.And the sensor typically cost for detecting vibration signal is relatively low, also generally simultaneously for laundry machine
In other control programs, such as uneven Detection ＆ Controling.
One of improvement the most of the invention, control device are arranged to suspend what is be currently running after judging driving belt failure
Washing and/or drying procedure, and the information that gives a warning.By this setting, the unnecessary waste of the energy is avoided, prevents clothing and machine
The damage of device, while user is notified in time, so that user contacts maintenance as early as possible.
As one of improvement of the present invention, warning message include the visual information that makes user learn driving belt failure and/
Or audio-frequency information.Where the usable family of this information and maintenance personal rapidly and accurately pinpoint the problems, so as to solve a problem promptly.
One of improvement as the present invention, sensor is acceleration transducer.
One of improvement as the present invention, sensor is fixedly connected on one of motor or outer barrel.As feasible
Other embodiment, sensor can be also located on the other components for the vibration component fixed relative to motor and outer barrel.
One of improvement as the present invention, if motor speed is more than preset rotation speed when the vibration signal measured is zero, is controlled
Device processed judges that driving belt fails.
One of improvement as the present invention, control device determine that motor is contorted according to detection motor real-time working power
State.The motor rotation status so obtained is relatively directly and easy.
One of improvement as the present invention, if the operating power of motor is more than default work(when the vibration signal measured is zero
Rate, then control device judge driving belt fail.
【Brief description of the drawings】
Fig. 1 is washing machine schematic diagram.
【Embodiment】
As shown in figure 1, washing machine 1 has a casing 2, the outer barrel 3 of a receiving cleaning solution is by hanging spring 4 and damper
5 are suspended in casing 2.Roller 6 is located in outer barrel 3 and driven and rotatable by motor 8.
Motor 8 is fixedly installed in outer barrel 3 by the mounting bracket 9 being attached thereto.One belt wheel 10 passes through rotary shaft 11
It is fixedly connected with roller 6.Belt wheel 10 is connected with motor driving shaft 13 by driving belt 14 simultaneously.Then motor 8 can band
Dynamic roller 6 rotates.Washing machine 1 also includes control device 15, and it sets the operating of controlled motor 8 according to program.
One acceleration transducer 16 is fixed on motor 8, and is connected with control device 15.When washing machine 1 works, example
When running washing and/or drying procedure such as washing machine 1, the driving drum 6 of motor 8 rotates.Due to filling loaded clothing in roller 6
Thing, rolled with the rotation of roller 6 or roller 6 is produced vibration close to the clothing that roller 6 rotates.Vibration is delivered to simultaneously
Outer barrel 3, motor 8 and other hung on the component that spring 4 and damper 5 are suspended.Acceleration transducer 16 is therefore detectable to shake
Dynamic signal, and the vibration signal is converted into electric signal and sent to control device 15.Meanwhile control device 15 also detects motor 8
Real-time working power, and determine therefrom that whether motor 8 is in rotation status, and/or determine the current rotating speed of motor 8.If
The operating power of motor 8 is more than a predetermined power when vibration signal measured is zero, and control device 15 judges driving belt 14
Failure.Predetermined power is usually zero.In other embodiments, also can measured motor 8 rotating speed, if the vibration signal measured is zero
When motor 8 rotating speed be more than preset rotation speed, then control device 15 judges that driving belt 14 fails.The preset rotation speed can be generally set to
Zero.
In order to which the information to be failed to user's reception and registration driving belt 14, control device 15 are temporary after judging that driving belt 14 fails
Stop washing and/or the drying procedure being currently running, and the information that gives a warning.This warning message is included on display 17 and shown
The visual informations such as word, mark, picture, and/or it is simultaneously emitted by the audio-frequency informations such as voice or buzzing.
Various embodiments described above and shown in the drawings are merely to illustrate the present invention, and non-invention
All.In the category of the basic fundamental thought of the present invention, the those of ordinary skill of correlative technology field is entered for the present invention
Capable any type of change is within protection scope of the present invention.
