Smokeless cooker

Abstract

A smokeless cooker includes a table located indoors, with a cabinet, which may include a plurality of individual boxes stacked and assembled together, below the table. A gas-discharge flow path leads from the cabinet to the outdoors. The cabinet includes an inner box with an open upper portion in an upper opening section of an outer box. An installed cooking means is located inside the inner box. A suction flow path is formed outside the inner box, with a suction hole in the inner wall of the suction flow path above a heating surface of the installed cooking means. The gas-discharge flow path includes a fat/oil filtering section, an absorption deodorizing section, a HEPA filter and a fan. A duct leading to the outdoors is present at the downstream side of the HEPA filter.

       3 . A separable smokeless cooker comprising: 
 a table; and    a plurality of boxes assembled below the table;    wherein an inside of each of the boxes is arranged as a flow path section and wherein neighboring flow path sections are connected to each other to form a gas-discharge flow path;    wherein an inner box having an open upper portion is formed in an upper opening section of an outer box provided in an upper box immediately below the table, and a placement table for placing a separately installed cooking means is formed within the inner box;    wherein a suction flow path communicating with the gas-discharge flow path is formed outside of the inner box, and wherein a suction hole communicating with the suction flow path is formed above a heating surface of the cooking means placed on the placement table;    wherein a fat/oil filtering section, an absorption deodorizing section, a HEPA filter, a fan, and an exhaust opening are disposed within the gas-discharge flow path; and    wherein a supplying opening is disposed between a downstream side of the HEPA filter and an upstream side of the exhaust opening in the gas-discharge flow path to enable a part of exhaust gas generated from the separable smokeless cooker to be sent through the supplying opening to the installed cooking means in the upper box.    
   
   
       4 . A separable smokeless cooker comprising: 
 a table; and    a plurality of boxes assembled below the table;    wherein an inside of each of the boxes is arranged as a flow path section, and wherein neighboring flow path sections are connected to each other to form a gas-discharge flow path;    wherein an inner box having an open upper portion is formed in an upper opening section of an outer box provided in an upper box immediately below the table, a cooking means is provided within the inner box, a suction flow path is formed outside the inner box, and a suction hole communicating with the suction flow path is formed above a heating surface of the installed cooking means;    wherein a fat/oil filtering section, an absorption deodorizing section, a HEPA filter, a fan, and an exhaust opening are disposed within the gas-discharge flow path; and    wherein a supplying opening is disposed between a downstream side of the HEPA filter and an upstream side of the exhaust opening in the gas-discharge flow path to enable the sending of a part of exhaust gas generated from the separable smokeless cooker through the supplying opening to the installed cooking means in the upper box.    
   
   
       5 . The separable smokeless cooker according to any of  claims 1  to  4 , wherein the fat/oil filtering section, the absorption deodorizing section and the HEPA filter are disposed in that order within the gas-discharge flow path.  
   
   
       6 . The separable smokeless cooker according to either of claims  3  or  4 , wherein the plurality of boxes is stacked together below the table, and wherein a side box is assembled together with the plurality of stacked boxes; 
 wherein the side box has a HEPA filter inside it;    wherein an exhaust opening is formed in the side face of the side box; and    wherein a supply port is formed communicating between the side box and the uppermost box in the plurality of stacked boxes immediately below the table.    
   
   
       7 . The separable smokeless cooker according to any one of  claims 1  to  4 , wherein the cooking means is a gas burner, and wherein a part of exhaust gas sent through the supplying opening is used for burning fuel gas with the gas burner.  
   
   
       8 . The separable smokeless cooker according to any one of  claims 1  to  4 , wherein the cooking means is an IH heater, and wherein a part of exhaust gas sent through the supplying opening cools the IH heater.  
   
   
       9 . The separable smokeless cooker according to any one of  claims 1  to  4 , wherein the cooking means is an electric heater using a resistive element, and
