Hello,
solution bellow.
There is disclosed a method of controlling an automatic door
opening/closing apparatus
for a washing machine that includes the steps
of determining whether or not there is an error in
an automatic door
opening or closing operation carried out in response to a command to
open or
close the washing machine's door; determining if the erroneous
operation has been
repeated more than a predetermined number of times
according to consecutive incoming commands to open or close the door;
and when erroneous operation has repeated more than the predetermined
number of times, ignoring a subsequent command to open or close the
door.
1. A method of controlling an automatic door opening/closing apparatus
for a washing machine door, the method comprising the steps of:
determining whether or not there is an error in an automatic door
opening or closing operation which operation is carried out in response
to a command to open or close the washing machine door;
determining if the erroneous operation is repeated more than a
predetermined number of times according to consecutive incoming
commands to open or close the washing machine door; and
in the
event that the erroneous operation is repeated more than the
predetermined number of times, ignoring a subsequent command to open or
close the washing machine door.
2. A method as set forth in claim 1, further comprising the step of: returning the door to the washing machine to an original position in the event that the error occurs.
3. A method as set forth in claim 1, wherein the step of determining if
there is an error in an automatic door opening or closing operation is
performed on the basis of whether or not an inversion occurs in an
open/closed state of the door within a prescribed period of time after
an automatic door opening or closing operation is initiated.
4. A method as set forth in claim 1, further comprising the step of:
clearing the number of errors in the case where the door of the washing
machine has been opened or closed manually at the time of occurrence of
the errors.
5. A method as set forth in claim 1, wherein said predetermined number is 3.
6. A method for controlling the operation of an automatic door
mechanism in a washing machine, said method comprising the steps of: sensing a command to automatically open or close a washing machine door;
sensing whether a failure occurs in opening or closing the door in
response to the command to automatically open or close the door;
incrementing a counter indicating the failure;
determining whether the counter is equal to a predetermined number; and
failing to engage the automatic door mechanism in response to a
subsequent a command to automatically open or close the door if the
counter exceeds the predetermined number.
7. The method claimed in claim 6, further comprising the step of: returning the door to an original position if a failure is detected.
8. The method claimed in claim 6, wherein failure is indicated by a
lack of a transition between a door open state and a door closed state
within a predetermined time period following entry of the command to
automatically open or close the door.
9. The method claimed in claim 6, further comprising the step of: clearing the counter if the door is opened or closed manually following a failure indication.
