Exhaust system for use in kitchen applications

Abstract

An exhaust system for use in a kitchen, the exhaust system including a hood body having a top rear panel, a left side panel, a right side panel, and a bottom rear panel. The exhaust system further includes a filter, a motor assembly, and a fan disposed at an angle relative to the top rear panel of the hood body. In one embodiment, the fan is disposed between the filter and the motor assembly and includes a plurality of paddles configured to disperse air from the fan radially outward in a direction perpendicular to a center axis of the fan. In another embodiment, the exhaust system is configured to be mounted to a side wall of the kitchen and to ventilate air from within the hood body through a vertical wall of the kitchen. In one embodiment, the exhaust system is for use in a mobile kitchen.

         7 . The exhaust system of  claim 4 , wherein the louvers are configured to prevent water from entering the vent duct, the motor assembly, and the fan. 
     
     
         8 . The exhaust system of  claim 4 , wherein the louvers are V-shaped. 
     
     
         9 . The exhaust system of  claim 8 , wherein a V-shaped angle of the louvers is about 40 degrees to about 70 degrees or about 51 degrees to about 60 degrees. 
     
     
         10 . The exhaust system of  claim 5 , wherein the external filter comprises a first wire mesh and a second wire mesh. 
     
     
         11 . The exhaust system of  claim 10 , wherein the first wire mesh and the second wire mesh are overlapped such that an undulating pattern of the first wire mesh is substantially perpendicular to an undulating pattern of the second wire mesh. 
     
     
         12 . The exhaust system of  claim 1 , wherein the kitchen is a mobile kitchen or a food truck kitchen. 
     
     
         13 . An exhaust system for use in a kitchen, the exhaust system comprising:
 a hood body comprising a top rear panel, a left side panel, a right side panel, and a bottom rear panel;   an internal filter, a motor assembly, and a fan disposed at an angle from the top rear panel of the hood body, and   an external filter system disposed at a distal end of the vent duct,   wherein the fan is disposed between the filter and the motor assembly and comprises a plurality of paddles configured to disperse air from the fan radially outward in a direction perpendicular to a center axis of the fan; and   wherein the exhaust system is configured to be mounted to a side wall of the kitchen and wherein the exhaust system is further configured to ventilate air from within the hood body through a substantially vertical wall of the kitchen using a vent duct.   
     
     
         14 . The exhaust system of  claim 13 , wherein the angle is between about 0 degree and about 90 degrees. 
     
     
         15 . The exhaust system of  claim 13 , wherein the air is ventilated through a vertical wall of the kitchen. 
     
     
         16 . The exhaust system of  claim 13 , wherein the external filter system comprises:
 an external filter that is slidably disposed within a frame track mounted around the periphery of the louver frame body;   a louver frame body; and   a set of V-shaped louvers mounted within the louver frame body.   
     
     
         17 . The exhaust system of  claim 16 , wherein the external filter comprises a first wire mesh and a second wire mesh that are overlapped one another such that an undulating pattern of the first wire mesh is substantially perpendicular to an undulating pattern of the second wire mesh. 
     
     
         18 . The exhaust system of  claim 13 , wherein the kitchen is a mobile kitchen or a food truck kitchen. 
     
     
         19 . A mobile kitchen, comprising:
