Abstract

Provided is an exhauster for a roaster which can exhaust the smell and the smoke which are generated when the meat is burnt in a restaurant, etc., to the outside of the restaurant. The exhauster includes: a hood tube in which a plurality of hood pipes can be combined so as to be folded in a multi-stage, and packings are applied to connection portions of the respective pipes to thereby prevent a gap from being formed between the connected hood pipes and the leak of the foreign matters from occurring; a hood main body having a space portion of a vertical direction length so that the contracted hood tube is completely inserted when the hood tube has been completely contracted, an exhaust tube having a fan which is installed at an axial portion in communication with the hood main body, and a bracket which is installed at the upper end thereof to then be fixed on the ceiling; and an elevating apparatus which is provided on the bottom of the bracket of the hood main body, including a winding reel around which a lifting chain is wound and a motor driving the winding reel, to thereby extend or contract the hood tube, in which the elevating apparatus is driven by a wireless remote controller.

1 . An exhauster for a roaster comprising: 
 a hood tube in which a plurality of hood pipes can be combined so as to be folded in a multi-stage, and packings are applied to connection portions of the respective pipes to thereby prevent a gap from being formed between the connected hood pipes and the leak of the foreign matters from occurring;    a hood main body having a space portion of a vertical direction length so that the contracted hood tube is completely inserted when the hood tube has been completely contracted, an exhaust tube having a fan which is installed at an axial portion in communication with the hood main body, and a bracket which is installed at the upper end thereof to then be fixed on a ceiling; and    an elevating apparatus which is provided on the bottom of the bracket of the hood main body, including a winding reel around which a lifting chain is wound and a motor driving the winding reel, and in which the other end of the lifting chain wound around the winding drum is connected with the upper end of the lowest hood tube where a hood is provided, to thereby extend or contract the hood tube by rotation of the winding reel, in which the elevating apparatus is driven by a wireless remote controller.    
   
   
       2 . The exhauster for a roaster according to  claim 1 , further comprising a diffuser playing a role of an oil receiver which is installed in a hood which is provided in the lowest hood tube with which a hood is connected by the medium of the bracket and an adjusting bolt.  
   
   
       3 . The exhauster for a roaster according to  claim 1 , wherein the hood is configured to have a plurality of vanes which are neighbor-arranged so as to be folded in the circumferential direction, in which the external diameter is expanded or reduced in the circumferential direction.  
   
   
       4 . The exhauster for a roaster according to  claim 2 , wherein the hood is configured to have a plurality of vanes which are neighbor-arranged so as to be folded in the circumferential direction, in which the external diameter is expanded or reduced in the circumferential direction.  
   
   
       5 . The exhauster for a roaster according to  claim 1 , wherein bolting holes are formed in both ends of the bracket of the hood main body, stay bolts on all the surfaces of which screw threads are formed are engaged with a pair of screw nuts which are installed in the upper and lower portions around the bracket, and the upper ends of the stay bolts are spirally engaged on the wall surface of a ceiling where the exhauster is installed and then fixed by screw nuts, to thereby minutely adjust height of the hood main body including the bracket and the hood tube according to adjustment of the tightening force of the screw nuts.  
   
   
       6 . The exhauster for a roaster according to  claim 1 , further comprising a limit switch having a connection structure which is connected with a motor which is installed in the connection portion at which the hood main body and the hood tube are connected, and a remote sensor having an electrical connection structure between the motor and the limit switch which is installed at the side of the hood main body, to thereby be possible to perform a remote control.
