Abstract
The invention discloses a belt dropping detection method for a motor of a drum washing machine or a washing-drying integrated machine. A CUP sends pulse to adjust the conduction angle of controllable silicon so as to drive the motor to rotate according to a set rotating speed, and the relationship between the motor and the belt is judged by detecting the size of the conduction angle of the controllable silicon in the rotating process of the motor so as to judge whether the motor and the belt are connected normally. A working program of the washing machine is provided with a critical value X of the conduction angle, and the critical value corresponds to the conduction angle of the corresponding controllable silicon when the belt is connected normally and an empty drum carried by the motor rotates; when the belt is connected normally and the drum carried by the motor is fed with clothes to rotate, and when the belt drops or is broken to cause separation between the motor and the drum and independently idle rotation of the motor, the conduction angles for controlling the normal rotation of the motor under the two conditions are different; and the relationship between the motor and the belt is judged by comparing the size of the detected conduction angle with the critical value X. The method has the characteristics of low cost and correct judgment.

The specific embodiment
A kind of roller washing machine of the present invention, washing-drying integral machine belt dropping detection method for motor, after starting working, thereby send out pulse by washing machine master control borad CPU and adjust silicon controlled conducting angle drive motors according to setting rotation speed operation, judge the relation of motor and belt by silicon controlled conducting angular dimension in the detection motor rotation process, thereby judge whether motor is connected normally with belt.
In general, after roller washing machine or the washing-drying integral machine work, motor begins to rotate will be through the process of a unstable rotating speed, as shown in Figure 1, abscissa t represents the motor rotation time, ordinate rpm represents motor speed, the process that its rotating speed was adjusted when on behalf of motor, curve rotate, behind operation a period of time t1, motor speed begins to stablize, and rotating speed is R, A point and later stage on the corresponding diagram 1, the process that only enters stabilization of speed is just sent instruction by master control borad CPU, detects the thyristor operating angle degree.
Process about the motor speed adjustment, also can be in order to prevent that skidding from appearring in belt, the reason that occurs skidding is that belt does not catch up with motor speed, this can appear at usually and start moment, acceleration is too fast this problem will to occur when setting, reach to set and detect the angle of flow and start moment that it doesn't matter after the stabilization of speed, also detect problem less than belt creep this moment by the angle of flow; In addition, because the belt pine that long operational time causes, rotating speed can be set the rotating speed low spot, but controllable silicon can transfer a little bigger angle of flow, rotating speed just to reach the setting rotating speed automatically, and therefore, the belt pine is a bit very little to rotating speed and the influence of the silicon controlled angle of flow.If belt is pine too, rotation will come off certainly.
In addition, if stall appears in motor, rotating speed will not reach the setting rotating speed; also can only maintain slow-speed of revolution action even controllable silicon is all opened rotating speed, this moment, all energy of motor were used for heating entirely, and temperature rises very fast; directly can cause motor protecter to disconnect, quit work, give the alarm.And, stall generally can be on artificial test or computer plate the electric motor loop components and parts with the appearance of staggering the time, under other situations almost there be not occurrence probability.
Extremely shown in Figure 4 as Fig. 2, coordinate system among the figure, abscissa T represents the thyristor operating angle degree, ordinate U represents voltage, the size of thyristor operating angle degree when the energy that consumes when dash area is represented motor rotation, shade are motor rotation in the part of abscissa correspondence, X, Y are determined values, the Z value is not a determined value, and is different with how many Z values of clothing.
Judge the relation of motor and belt by silicon controlled conducting angular dimension in the detection motor rotation process, at first to establish a conducting angle critical value X in the washing machine working procedure, as shown in Figure 2, this critical value X corresponds to belt and connects just often that the motor band carries the corresponding down thyristor operating angle degree of empty bucket running, when belt connects just often the motor band and carries bucket and add the clothing running, when causing motor to separate motor with bucket when belt dropping or disconnection to dally alone, the conducting angle that the control motor runs well under two kinds of situations is different, compare by detected conducting angular dimension and critical value X, thereby judge the relation of motor and belt.
Silicon controlled conducting angle critical value X when belt connection normal motor band carries empty barrel of running, be by substantive test to complete machine, the determined value that detects, detected conducting angle is worth therewith and contrasts under other states, just can judge whether belt and motor are connected normally, simultaneously, as shown in Figure 4, also can test out the not corresponding down thyristor operating angle degree of self running when carrying of motor, this also is a stationary value, may be defined as Y; When detected conducting angle in the operation process was a bit larger tham or is equaled Y, it was unusual to conclude immediately that then belt connect to occur, and came off or disconnected.
As shown in Figure 5, the concrete steps of belt dropping detection method for motor of the present invention are:
A, start working, CPU sends out the drive motors running of pulse control controllable silicon and carries out speed governing;
B, reach and detect silicon controlled conducting angle Z under the stable state after setting rotating speed;
C, judge detected conducting angle Z, and it and X value are compared, conclude then that when satisfying Z＞X motor is connected with belt normally; Otherwise, represent that then motor and belt work are undesired.
This is the process of an adjusting to electric machine speed regulation to setting stable state rotating speed R among the step a, judges whether to reach the rotating speed R of stable state through speed governing, does not then continue to adjust if reach, until reaching this rotating speed.
Begin fault detect after step c motor and belt work are undesired,, judge then whether Z satisfies Y≤Z＜X if Z does not satisfy Z＞X, if, then represent belt dropping or disconnection, send belt dropping or disconnect reminder alarm, quit work; If not, judge then whether Z satisfies Z＜Y, if, then represent the motor speed measuring loop fault, giving the alarm quits work; If not, represent that then the Z=X motor is connected normal and the bucket clothing amount is less with belt, work on.
Certainly Z=X may represent that also the user forgets that placing in the clothing bucket is the situation of empty bucket, at this situation, on one side program is set to an edge work and gives the alarm, after a period of time, stops alarm, and operate as normal also can be selected to control it by the user and stop alarm.
Described reminder alarm adopts the color tips lamp of corresponding different faults or display screen to show failure code, and/or send different types of sound or voice prompt alarm.
Whether the present invention can guarantee to judge accurately belt and disconnect or come off, and in time stops washing or in time stops heating, drying and timely call user's attention, gets rid of the hidden danger that clothing can't normally be cleaned drying in washing process; More than long-time possibility that is crumpled of piling up of clothing of getting rid of has also been got rid of the potential safety hazard that lasting heating brings in drying course.In addition, the present invention adopts the size that detects the thyristor operating angle degree to judge that whether belt disconnects or come off, and has reduced the cost of use sensor judgment mode.
