The washing machine realizing the object of the invention comprises control unit, and described control unit controls motor, and motor makes cylinder clockwise and/or be rotated counterclockwise.The motors designs one-tenth used in washing machine is at electric current that is clockwise or consumption varying level when being rotated counterclockwise.The electric current consumed in second direction is greater than at the electric current of the first direction of rotation consumption.It is larger that reason is that motor torsional moment is designed at first direction.If starting mistake to be detected in the motor rotated with first direction, so motor is stopping and rotating with second direction after waiting a period of time.
In one embodiment of the invention, if detect that motor accelerates more than hope, so motor is stopped and rotates with second direction.Owing to supplying energy to the switch short of motor, unbroken energy supply is supplied to motor motor is accelerated gradually.If the non-eliminating error when motor stops, so motor rotates with second direction, because again unexpected mistake of motor will be made to accelerate with first direction rotation motor.
In another embodiment of the present invention, when motor consumption being detected than normal more electric current, motor is stopped to prevent motor from heating.When motor will operate again, by making motor rotate towards second direction, current sinking amount can be detected when not having motor overheated.
In one embodiment of the invention, if owing to detecting that mistake causes continuous motor shutdown number of times to reach manufacturer's number of times pre-recorded in control unit memory, so by judging that described mistake is not eliminated by shutdown, program stops together.
By means of control unit of the present invention, when detect with motor operated relevant wrong time, motor is stopped and rotates with second direction.Thus, start whether can detect again making a mistake when not jeopardizing security during second direction slow circumvolve at motor.

Detailed description of the invention
Washing machine of the present invention (1) comprising: cylinder (2), waits to wash clothes to be placed in cylinder (2); Motor (3), described motor (3) makes cylinder (2) rotate with the rotary speed being suitable for washing procedure, described washing procedure comprise main to wash, rinsing and drying step; And control unit (4), described control unit (4) controls the operation (Fig. 1) of motor (3) according to the washing procedure that user selects.
The method that control unit (4) records in its memory according to manufacturer and make motor (3) in washing procedure clockwise and/or be rotated counterclockwise according to the program that user selects.In washing step, motor (3) usually continuously to turn clockwise certain hour section and be rotated counterclockwise certain hour section, thus makes clothes stir in cylinder (2) and washing.In drying step, motor (3) mostly just rotates with high speed facing one direction, because it is by performing drying process with High Rotation Speed.
Motor (3) current drain (11) be designed to when motor (3) rotates with first direction (d1) is greater than the current drain (12) when motor (3) rotates with second direction (d2).Because motor (3) is larger and consume more multiple current at the moment of torsion of first direction (d1), therefore perform drying process with this direction (d1).In washing step, motor (3) rotates long-time section with second direction (d2) and rotates short time period with first direction (d1), thus less energy is provided for consuming, because motor (3) rotates longer time section with second direction (d2), this is that motor (3) consumes less sense of current.
The operation of control unit (4) monitoring motor (3) in washing and drying step, and stop motor (3) when mistake being detected.After waiting for the time period of recording in its memory, control unit (4) starter motor (3), makes motor (3) rotate with second direction (d2).Thus, in the unrepaired situation of mistake during shut down period in motor (3), prevent motor (3) from starting to rotate and cross to accelerate, until again mistake detected with first direction (d1).Motor (3) be configured to when again operating with second direction (d2) rotate, and if acceleration before problem overcome not yet, so revolution is limited, until mistake detected, because motor (3) slowly accelerates at this direction (d2).
In one embodiment of the invention, washing machine (1) comprises switch (5), and switch (5) provides energy to be supplied to motor (3).When detecting that motor (3) crosses acceleration due to the middle short circuit of switch (5), control unit (4) stops motor (3) and makes when again operating motor (3) rotate with second direction (d2).Thus, if the short circuit problem of switch (5) does not correct, so mistake can be detected before motor (3) accelerates.
In another embodiment of the present invention, when control unit (4) detects that motor (3) consumed multiple current, it stops motor (3) and makes when again operating motor (3) rotate with second direction (d2).Due to the overload of cylinder (2) or the uneven distribution of the middle clothes of cylinder (2), motor (3) consumed multiple current by strain (straining).When consuming multiple current, motor (3) was overheated.Its life span is shortened in the heating of motor (3).If the clothes be adhered on cylinder (2) wall does not scatter, so when control unit (4) detects that motor (3) stopped after motor (3) consumed the problem of multiple current, by preventing motor (3) from rotating with first direction (d1), prevent cylinder (2) by accelerating at once and moving in uneven mode.
In one embodiment of the invention, if make when mistake being detected motor (3) towards second direction (d2) rotate after detect errors number be greater than the number of times recorded in its memory, so control unit (4) shut down procedure and warning user.Thus, when mistake can be corrected, control unit (4) recovery routine.When mistake can not be corrected, control unit (4) warns user by end program, thus mistake can not damage washing machine (1) or injury user.
By means of the present invention, when mistake being detected when performing washing procedure, motor (3) is stopped and waits for certain hour section, and motor (3) is rotated towards second direction (d2).Thus, if within the time period that motor (3) remains on shutdown mode non-eliminating error, so by towards first direction (d1) rotate prevent motor (3) cross accelerate and prevent damage washing machine (1), until mistake detected.
