Rice Cooker Durability Tester

The Rice Cooker Lid Opening and Closing Durability Tester is designed to evaluate the long-term mechanical reliability of rice cooker lid mechanisms. You use this system to automatically press the lid release switch, while a pneumatic push rod and motor-driven fixture repeatedly open and close the lid. By accurately simulating frequent user operations, the tester enables aging and durability evaluation of the lid structure under controlled and repeatable conditions, including dual-switch testing capability.

Applications

This tester is suitable for lifecycle and durability testing of lid opening and closing mechanisms in household cooking appliances, including:

• Rice cooker lid opening and closing mechanisms

• Electric pressure cooker lid structures

• Lid release switches and related mechanical linkages

• Sealing ring and lid-related structural components

5.Start the test to simulate repeated lid opening and closing actions.

6.The system automatically counts cycles and stops when the preset value is reached or an alarm is triggered.

FAQ

1. What types of products can you test with this equipment?

You can test rice cookers, electric pressure cookers, and similar appliances with lid opening and closing mechanisms.

2. Can you adjust the opening and closing speed?

Yes. The action time for each control cycle is adjustable through the touchscreen interface.

3. Does the tester support long-duration durability testing?

Yes. It is designed for continuous operation to support aging and lifecycle durability tests.

4. How does the machine ensure test safety?

The system includes leakage protection, undervoltage protection, automatic alarms, and automatic shutdown when preset limits are reached.

5. Is the operation complicated for operators?

No. All parameters and status information are managed through a clear touchscreen interface with menu-based operation.

6. Can the tester evaluate sealing-related components?

Yes. Repeated lid operation allows you to assess the durability of sealing rings and related mechanical structures during aging tests.
