Technical Specification for Intelligent Level of Household Range Hoods

Technical Specification for Intelligent Level of Household Range Hoods

• The standard is published by the China Standardization Association (CAS) on October 10, 2019.
• The standard is implemented by the CAS, which is a national social organization that organizes domestic and international standardization activities.

Smart Level Evaluation

• The smart level of a household range hood is determined by its intelligent functions, which are evaluated based on the requirements and detection methods specified in the standard.
• The smart level is represented by a smart index, which is a combination of letters and numbers (e.g., "5A0B" or "nB").

Intelligent Functions

• There are 19 intelligent functions, including:
  • Functional safety
  • Information technology security
  • Self-diagnostic function
  • Running mode adaptation (smart mode)
  • Network module OTA (over-the-air) update
  • Appliance control function OTA update
  • Health maintenance reminder
  • Cleaning function
  • User habit learning function
  • Voice control function
  • Remote control function
  • Multimode interconnection function
  • Smoke duct self-adaptation function
  • Intelligent ventilation function
  • Multi-platform interconnection function
  • Smoke alarm interconnection function
  • Gesture control function

Evaluation Criteria

• Each intelligent function has a specific evaluation criterion, which includes a scoring rule and a passing score.
• The scoring rule is based on the degree of implementation of the intelligent function, with a maximum score of 20-50 points depending on the function.
• The passing score is 3B or above, which indicates a high level of smartness.

Safety and Security

• The standard requires that the household range hood meets the safety and security requirements specified in the standard, including functional safety, information technology security, and health maintenance.
• The standard also requires that the household range hood has a self-diagnostic function to detect and report any faults or errors.

OTA Update

• The standard requires that the household range hood has an OTA update function, which allows the user to update the software and firmware remotely.
• The OTA update function should be secure, reliable, and efficient, and should not affect the normal operation of the household range hood.

User Habit Learning

• The standard requires that the household range hood has a user habit learning function, which can learn and adapt to the user's habits and preferences.
• The user habit learning function should be able to learn the user's usage patterns, including the time, mode, and duration of use.

Voice Control

• The standard requires that the household range hood has a voice control function, which can accept voice commands and execute corresponding actions.
• The voice control function should be able to recognize and respond to voice commands accurately and efficiently, and should have a low error rate.
