Range Hood

Abstract

The present invention provides a range hood comprising a casing, a partition plate, a motor, a fan, a protective net, a filter screen, a fixation holder and a screen cover, characterized in that said fixation holder configured under said filter screen has one end pivotally connected with a hollow joint of said partition plate inside the bottom portion of said casing, the other end clasped with a resilient hooked plate of said partition plate, and a middle section holding said filter screen. Therefore, the present invention provides a function that said filter screen may be secured and replaced not only easily but also quickly.

What is claimed is: 
     
         1 . A range hood comprising:
 a casing having a bottom portion arranged with a partition plate partitioning off the interior of said casing as a hollow chamber, and a top surface arranged with at least one fume outlet connecting said chamber, wherein said partition plate is provided with a fume inlet corresponding to said chamber;   a motor having a top surface fixed to said casing provided with a drive axle secured to the center of a fan, and wherein said fan is configured inside said chamber and corresponds to said fume inlet ;   a protective net which is arranged under said fume inlet and which is provided with an outer margin fastened to the bottom surface of said partition plate;   a filter screen arranged under said protective net for absorbing, filtering and purifying fumes;   a fixation holder configured under said filter screen, having one end pivotally connected with a joint of said partition plate, the other end clasped with a resilient hooked plate of said partition plate, and a middle section holding said filter screen; and   a screen cover configured under said filter screen having two ends respectively secured to said casing.   
     
     
         2 . The range hood as claimed in  claim 1 , wherein said fixation holder is in the shape of a trapezoid provided with a bottom base having two sides respectively disposed with a pivot pin protruding outward for inserting into said hollow joint of said partition plate so as to enable the both to be pivotally connected with each other, and a top base clasped with a resilient hooked plate of said partition plate; wherein said resilient hooked plate has a curved shape and the back thereof is arranged toward said joint. 
     
     
         3 . The range hood as claimed in  claim 2 , wherein said hollow joint and said resilient hooked plate are formed with the body of said partition plate in an integral stamping mode 
     
     
         4 . The range hood as claimed in  claim 3 , wherein said filter screen is an activated carbon filter screen. 
     
     
         5 . The range hood as claimed in  claim 4 , wherein a back plate arranged to said casing may also be disposed with said fume outlet; wherein said fume outlets configured to said back plate and the top surface of said casing may be opened or closed according to the work area where the range hood is mounted and the needs of the users. 
     
     
         6 . The range hood as claimed in  claim 5 , wherein a fume filter arrangement may be configured at said fume outlet to increase the filtering efficiency if the filtered fumes are exhausted indoors. 
     
     
         7 . The range hood as claimed in  claim 2 , wherein said screen cover has one end placed onto a folded lip of the bottom margin of said the back plate, and the other end arranged with a retractable pin allowed to extend outwards to be inserted into a hole of said casing so as to be secured to said casing; wherein said folded lip is flat folded toward the inner side of the casing, and moreover said retractable pin is controlled by a hand-pull plate to be able to withdraw inwards so as to be unfastened.
