Auxiliary equipment for kitchen hood improving extraction and anti-splashing cooking oil

Abstract

This invention relates to the auxiliary equipment for kitchen hood with the purpose of preventing the cooking odors and oil from spreading out the kitchen. The auxiliary equipment includes a rectangular frame designed in module type, curtains, and brackets to fix the auxiliary equipment to a kitchen hood. The frame includes four frame modules assembled together with curtain rollers having curtains fitted inside the frame modules. The curtain rollers rotate to raise or lower the curtains simultaneously. When the curtains are lowered a temporary enclosure is provided. The curtains are made of transparent material to prevent cooking odors and cooking oil from escaping the enclosure. The curtains are provided with fire-proof footage to keep the curtains safe. Small slits are provided on the curtains to help the cook to easily observe and handle food being cooked within the enclosure.

1 . An auxiliary equipment for a kitchen hood, that aims to improve extraction and anti-splash cooking oil, comprising a rectangular frame ( 2 ) designed in modular type, curtains ( 3 ) and a bracket ( 8 ) to couple the auxiliary equipment with the kitchen hood;
 wherein the frame ( 2 ) comprises a plurality of modules that are assembled together, each of the plurality of modules having a curtain roller ( 15 ) coupled with a curtain ( 3 ) positioned therein,   wherein the curtain roller ( 15 ) is configured to rotate to lower or raise the curtain ( 3 ), and   wherein the curtains ( 3 ) are configured to at least partially enclose a cooker, and are made of transparent material to prevent odors and oil splashing, the curtains ( 3 ) having footages ( 4 ) made of fire-proof material to keep the curtains ( 3 ) safe, the curtains ( 3 ) having at least one small slit ( 7 ) for observing a space within the curtains ( 3 ).   
     
     
         2 . The auxiliary equipment according to the  claim 1 , wherein the frame ( 2 ) includes:
 two first frame modules ( 16 ) opposite with each other, each first frame module ( 16 ) having a drive gear ( 12 ) coupled with a cable reel ( 10 ) to wind a cable ( 13 ), the drive gear ( 12 ) coupled with the curtain roller ( 15 ), wherein the curtain roller ( 15 ) is removable and rotatable simultaneously with a shaft of the drive gear ( 12 ), wherein one of the first frame modules further comprises a turning-braking gear ( 19 ) on the shaft of the drive gear ( 12 ) to prevent rotation of the curtain roller ( 15 ), the turning-braking gear ( 19 ) interlocked with a braking pin ( 9 ) interlocked with the turning-braking gear ( 19 ); and   two second frame modules ( 17 ) opposite with each other, each second frame module ( 17 ) having a driven gear ( 11 ) coupled with the curtain roller ( 15 ), each second frame module also having a tension spring ( 14 ) housed therein and coupled to the cable ( 13 ), wherein the curtain roller ( 15 ) is removable and rotatable simultaneously with a shaft of the driven gear ( 11 ), wherein each drive gear ( 12 ) is coupled with a corresponding driven gear ( 11 );   wherein the curtain rollers ( 15 ) are rotatable simultaneously such that the curtains ( 3 ) are raised and lowered together and the curtain rollers ( 15 ) are lockable such that the curtains ( 3 ) are maintained at the same level.   
     
     
         3 . The auxiliary equipment according to the  claim 2 , wherein each cable reel ( 10 ) is fixed on the shaft of each drive gear ( 12 ) to wind and unwind the cables ( 13 ) and to rotate the drive gears ( 12 ) and the turning-braking gear ( 19 ),
 whereby when any one of the curtains ( 3 ) is lowered each tension spring ( 14 ) is expanded and the curtains ( 3 ) are locked into place by the turning-brake gear ( 19 ), and   whereby when the braking pin ( 9 ) is released, the turning-brake gear ( 19 ) is disengaged and each tension spring ( 14 ) is retracted to unwind the cables ( 13 ) and rotate the cable reels ( 10 ) such that the curtains ( 3 ) are raised simultaneously.
