COMBINED AIR SUPPLY PORT FOR RANGE HOOD AND 24-HOUR VENTILATION
Document Type and Number:
Japanese Patent JP2023159766
Kind Code:
A
Abstract:
To solve the problems that there is high cost of materials and construction due to the installation of two air supply ports for ventilation at the time when a differential pressure airflow occurs due to 24-hour ventilation between the air supply ports and a range hood, and that there are an unsightly appearance and restrictions on the arrangement of indoor furniture due to the installation of the two air supply ports.SOLUTION: The present invention is an air supply port for ventilation that is attached to a wall facing outside air between the indoor and outdoor areas of an apartment or a detached house, where a differential pressure opening/closing flap is provided in the air supply port that automatically opens and closes as airflow is generated due to the differential pressure between the indoor and outdoor areas; a gap for 24-hour ventilation is provided at either the top, bottom, left or right end of the differential pressure opening/closing flap; and one air supply port has two functions of: air supply for ventilation at the time when a differential pressure airflow occurs due to the operation of a range hood, etc.; and 24-hour ventilation.SELECTED DRAWING: Figure 2
