AI Technical Summary
Existing ventilation systems face challenges in minimizing the space required to open their doors, particularly when installed in spaces with obstructions like washing machines or refrigerators, making maintenance difficult.
The ventilation system features a case with a plurality of doors that can be opened in specific directions, allowing the total heat exchanger and filters to be separated downward, and a door hinge design that minimizes the space needed for opening, enabling easy access for maintenance.
This configuration reduces the space required to open the doors, allowing for easy filter replacement and maintenance without obstructing nearby items, enhancing usability and accessibility.
