Standard description:
20.101 Appliances shall have means to prevent opening of the door
during operation or an interlock which disconnects the motor before
the door opening exceeds 75 mm. It shall not be possible to start
the motor while the door opening exceeds 75 mm. For appliances with
a door opening having a dimension exceeding 300 mm and a drum
having a volume exceeding 100 dm³ , starting of the motor shall not
be possible until a separate means which controls the movement of
the drum is operated manually. However, for appliances loaded from
the front, the dimension are reduced to 25 cm for the door opening
and 75 dm³ for the drum volume.
Interlocks shall be constructed so that unexpected operation of the
appliance is unlikely to occur while the door is open.
Compliance is checked by inspection, by measurement and by manual
test with the appliance supplied at rated voltage and under normal
operation .
If means to prevent the door opening incorporates a coil or similar
component to lock the door in the closed position, the component is
energized and de-energized 6 000 times, six times a minute or at
the rate imposed by the construction of the appliance if this is
lower.
The locking means and its components shall be fit for further use.
NOTE 1 The door is opened and closed during the test if this is
necessary for the mechanical operation of the interlock.
NOTE 2 Interlocks which can be released by means of the test finger
shown in figure 1 are considered likely cause unexpected operation
of the appliance.
Product information:
The washing machine door performance tester is special designed and
manufactured as per IEC 60335-2-7 household and similar electrical
appliances – safety: part 2-7: particular requirements for washing
machines, clause 18.101and clause 22.104; IEC 60335-2-11 household
and similar electrical appliances – safety: part 2-11: particular
requirements for tumble dryers, clause 20.101. It is a special
equipment for durability and structural testing of washing machine.
The equipment adopts advanced PLC intelligent control system, touch
screen humanized operation interface to make recording and display
more accurate; with preset test times, on current detection, load
voltage regulation and display, test speed, test stroke, open /
close door pull force setting, pull force transient curve display,
test data storage and query, fault alarm and other functions, can
be analyzed by the data record whether the test sample is qualified
or not. The whole machine is divided into tumble washing machine
test station, wave-wheel washing machine test station, and
beautiful appearance; stable performance and convenient operation.
It is the first choice for large metrology institutions and
laboratories.
