Smoke Exhaust

Abstract

A smoke exhaust having a housing formed with a wind chamber for creating pressure and a guiding chamber for guiding the smoke. The guiding chamber has a sucking mouth formed on front section of the housing. An upright filter mesh assembly is disposed at the sucking mouth for filtering the smoke and collecting oil dirt. The guiding chamber has a rear face formed with a bottom edge. A guiding face forward and upward extends from the bottom edge to the sucking mouth for guiding smoke to the sucking mouth.

What is claimed is:  
     
         1 . A smoke exhaust comprising a housing formed with two internal spaces, one of the spaces being a wind chamber for creating pressure, while the other being a guiding chamber for guiding the smoke, the wind chamber having an outlet communicating with outer side of the housing and an inlet communicating with the guiding chamber, the guiding chamber surrounding the wind chamber and having a compartment defined between the inlet of the wind chamber and the guiding chamber for air to smoothly flow therethrough, the guiding chamber further having a sucking mouth formed on one side of the housing proximal to an oven, an upright filter mesh assembly being disposed at the sucking mouth, the guiding chamber having a rear face formed with a bottom edge, a guiding face forward and upward extending from the bottom edge to the sucking mouth for guiding smoke.  
     
     
         2 . A smoke exhaust as claimed in  claim 1 , wherein the guiding chamber further has two downward extending side walls, the side walls and the guiding face defining therebetween a smoke collecting space.  
     
     
         3 . A smoke exhaust as claimed in  claim 1 , wherein the filter mesh assembly includes a frame body in which a filter mesh is disposed, a bottom of the frame body being formed with a sink having an opening, an oil cup being placed into or taken out from the sink through the opening, the frame body having at least one window between the sink and the filter mesh, whereby the oil dirt accumulating on the filter mesh can flow through the window into the oil cup.  
     
     
         4 . A smoke exhaust as claimed in  claim 1 , wherein the sucking mouth has a top face and a bottom face respectively formed with an upper and a lower locating dents, the frame body of the filter mesh assembly being located between the upper and lower locating dents.  
     
     
         5 . A smoke exhaust as claimed in  claim 1 , wherein at least one upper leaf spring is disposed in the upper locating dent for resiliently downward pressing and locating the filter mesh assembly in the upper and lower locating dents.  
     
     
         6 . A smoke exhaust as claimed in  claim 1 , wherein the sucking mouth has a left and a right side walls on which two lateral leaf springs are respectively disposed, the sucking mouth further having an opening facing downward, whereby the filter mesh assembly can be upward mounted at the sucking mouth through the opening, the frame body of the filter mesh assembly being formed with a dent corresponding to each of the lateral leaf springs for locating the lateral leaf springs.
