storage conditions where a washing machine might be placed in an
unheated garage during winter, as well as the high - temperature
environments in laundromats or in hot climates. The temperature
control accuracy is within ±0.5°C, ensuring consistent and reliable
test conditions. For example, testing the performance of the
washing machine's motor and electronic control board at high
temperatures can help identify potential overheating issues.
- Humidity Regulation: Humidity levels can be precisely adjusted from 10%RH to 95%RH.
High humidity in areas like coastal regions or basements can cause
corrosion of metal components and affect the functionality of
electrical parts. Low humidity, on the other hand, may lead to
problems such as static electricity build - up in the drum. By
accurately simulating different humidity levels, manufacturers can
test the moisture - resistance of the machine's internal
components, including the wiring, sensors, and metal housing.
- Airflow and Ventilation Simulation: Some advanced chambers are equipped with systems to simulate
natural airflow and ventilation. This is crucial as proper
ventilation affects the drying performance of washing machines with
integrated dryers. By controlling the airflow rate and direction,
manufacturers can optimize the drying cycle, ensuring efficient and
uniform drying while preventing issues like over - drying or uneven
drying.
2.2 Customizable Test Profiles
- User - Defined Cycles: The testing chamber allows users to create customized test
cycles. Manufacturers can set specific temperature - humidity -
time profiles to mimic the actual usage scenarios of washing
machines in different geographical locations and usage patterns.
For instance, a cycle could be designed to simulate the temperature
and humidity changes in a household laundry room over a day, with
variations in temperature during different times and humidity
levels affected by the machine's operation.
- Multi - Stage Testing: It supports multi - stage testing, where different environmental
conditions are applied in sequence. For example, a test could start
with a high - temperature and high - humidity phase to simulate
summer operation, followed by a low - temperature and low -
humidity phase to represent winter conditions. This helps in
evaluating the long - term durability and performance of the
washing machine under changing environmental factors.
2.3 Robust and Safe Design
- Durable Construction: The chamber is constructed using high - quality materials to
withstand continuous use and the rigors of different environmental
conditions. The interior is designed to be corrosion - resistant,
especially in high - humidity test scenarios. The insulation
materials ensure energy - efficient operation and prevent heat loss
or gain, maintaining the stability of the internal climate.
- Safety Features: Multiple safety features are incorporated into the design. Over -
temperature protection prevents the chamber from overheating, which
could damage the test samples or the equipment itself. Leak -
detection systems are in place to identify any water or refrigerant
leaks, ensuring safe operation, especially when testing washing
machines with water - related functions. Additionally, emergency
stop buttons are easily accessible for immediate halting of the
test in case of any unforeseen issues.
