Problems solved by technology

However, due to the bonding effect of oil stains (the oxidized high-temperature oil fume is a kind of viscous colloid after being gathered), the above-mentioned damper may be biased to one side (a semi-circular piece is biased to the other side) or still in a vertical state. Two major deficiencies that don't self-relocate and therefore need to be improved

Embodiment Construction

[0012] Such as figure 1 , shown in 2, a kind of manufacture method of the reed type damper of range hood, eliminates above-mentioned defect with this; Plate body; the two ends of the reed 2 are connected with a chuck 3, and the chuck 3 is a giant (jumbo frame shape) clamp made of elastic steel wire; A section of the shaft head 4; the chuck 3 connected to the shaft head 4 can be deformed and restored under the action of its own elasticity; one side of the chuck 3 (referring to the back of the rectangular frame that is connected to the reed) is flattened, The flattened chuck 3 and the two ends of the reed 2 are fixedly connected into one; the total length of the reed 2 and the chuck 3 is equal to the diameter of the damper 1;

[0013] Two parallel protrusions 5 are respectively added above the two air doors 1, and the protrusions 5 are made into an isosceles trapezoid with a plate body; the length of each section of protrusions 5 is less than the width of each damper 1, and th...

Abstract

The invention provides a manufacturing method of reed air doors for a smoke exhauster. According to the air doors, a reed is additionally arranged on semi-circular chips of existing air doors, and chucks are connected to the two ends of the reed. Two parallel protrusions are additionally arranged on the two air doors correspondingly. A row of shaft holes are drilled in the middle of the height of each protrusion. Shaft heads on the chucks at the two ends of the reed are installed in the symmetrical shaft holes of the two air doors correspondingly. The reed fixedly installed is erected over the two air doors in an arch shape. A circle of protruding circular rings are additionally arranged on the planes, making contact with an air outlet of the smoke exhauster, of the air doors, so that the plane contact area between the air doors and the air outlet is reduced.

Description

technical field [0001] The invention discloses a method for manufacturing a reed damper of a range hood, which belongs to the field of cooking supplies. Background technique [0002] At the connection between the existing range hood and the spiral flue (hose), there is a one-way damper to prevent the smoke in the public exhaust flue from being poured into the kitchen at home. However, the current Most of the dampers used are made of two semicircular plastic sheets (thickness between 1-1.5 mm, referred to as semicircular). In the shaft hole above the channel support plate (the shaft hole is set on the side wall of the main body of the air channel), the installed damper can rotate upwards and open vertically under the impact of the range hood airflow, thereby minimizing the impact of the damper Airflow resistance; when the range hood stops working, the two half-circles of the damper fall back to their original positions by their own gravity, thereby preventing the (counteratt...
