AI Technical Summary

Technical Problem

Existing fresh air type range hoods cannot effectively adjust the fresh air temperature when used in winter and summer, resulting in poor comfort and low oil fume removal efficiency.

Method used

A fresh air range hood is designed with summer and winter working modes. The summer mode uses the radiator and metal side walls for cooling, while the winter mode uses the hot air from the oil smoke to preheat the fresh air. Combined with the oil collection grid and oil collection chamber structure, it improves the oil fume removal efficiency and facilitates cleaning.

Benefits of technology

In winter mode, it preheats the fresh air to improve indoor temperature comfort, and in summer mode, it lowers the indoor temperature. The oil collection grid structure is easy to clean and improves the oil fume removal efficiency, making it suitable for commercial environments with large oil fumes.
