The angle of the exhaust pipe should be slightly inclined upward (one end of the flue interface is high, and the other end of the range hood is low), because the temperature of the kitchen oil fume steam is high and it diffuses upward, especially the initial speed of oil fume generation is extremely high. What should I do if the smoke exhaust effect of the range hood is not good? The angle of the smoke exhaust pipe is slightly inclined upward, which is beneficial to the discharge of kitchen fumes and water vapor. Generally speaking, the greater the air volume, the more quickly and timely a large number of kitchen fumes can be sucked out and discharged. The greater the wind pressure, the stronger the anti-suction ability of the range hood.

Reason 2: The length of smoke exhaust pipe affects the smoke exhaust effect.

Reason 3: The installation height of the range hood affects the smoke exhaust effect.

The installation height of the range hood generally depends on the site conditions, and its lower edge is generally 6 10-750mm away from the counter. However, practice has proved that the lower edge of the range hood is 6 10mm away from the cabinet table, instead of 750mm away from the cabinet table.
