Ventilator

Abstract

The present invention relates to a ventilator. Channels are horizontally extended in the interior of a total heat exchanger. The channels are vertically stacked for thereby enhancing the efficiency of heat exchange.

1 . A ventilator, comprising: 
 a casing;    a flow path formed in the inside of the casing, and sucks in and discharges indoor air and/or outdoor air; and    a total heat exchanger connected to the flow path includes a plurality of channels for allowing the indoor air and/or outdoor to flow through, and the upper and lower surfaces of the total heat exchanger are blocked.    
   
   
       2 . The ventilator of  claim 1 , further comprising a blower provided adjacent to the total heat exchanger.  
   
   
       3 . The ventilator of  claim 1 , wherein the total heat exchanger is hexahedron shape formed in a horizontal direction.  
   
   
       4 . The ventilator of  claim 1 , wherein the channels are stacked from top to bottom order.  
   
   
       5 . The ventilator of  claim 1 , wherein fins-are provided in the inside of the channels for enhancing the heat exchange efficiency.  
   
   
       6 . The ventilator of  claim 1 , wherein the channels are extended in a straight line shape.  
   
   
       7 . The ventilator of  claim 1 , wherein the total heat exchanger includes: 
 a lower frame and an upper frame that are blocked and formed in the upper and lower sides, respectively; and    a side frame setting the channel inside, and connects said upper frame and the lower frame outside.    
   
   
       8 . The ventilator of  claim 1 , wherein a horizontal cross section of the total heat exchanger is a rectangular shape, and an apex of the same is formed in the direction of an inner surface of the casing.  
   
   
       9 . The ventilator of  claim 1 , wherein at least one pair of the outdoor air suction part and discharge part and/or the indoor air suction part and discharge part have the air that has been sucked in or exhausted flows in parallel direction.  
   
   
       10 . The ventilator of  claim 1 , wherein at least one of the outdoor air and/or indoor air suction part or discharge part is separately formed at the side surface of the casing.  
   
   
       11 . The ventilator of  claim 1 , wherein a ventilation duct that connects the indoor air suction part and discharge part is provided in the flow path, and said ventilation duct is not connected with the total heat exchanger.  
   
   
       12 . The ventilator of  claim 1 , wherein said flow path includes at least one ventilation duct that is not connected with the total heat exchanger, and a flow path switch means which performs the switching function of another duct connected to the total heat exchanger and the ventilation duct.  
   
   
       13 . The ventilator of  claim 1 , wherein at least one fan is provided in the flow path.  
   
   
       14 . A ventilator, comprising: 
 a casing;    a total heat exchanger that is provided in the inside of the casing wherein indoor air and/or outdoor air flow through horizontally extended channels, and the upper and lower sides of the total heat exchanger are blocked;    a suction duct and a discharge duct that guide the outdoor and indoor air in the direction of the total heat exchanger wherein an outer portion of the casing is connected with the total heat exchanger; and    a fan formed in the interior of the suction duct and/or the discharge duct.    
   
   
       15 . The ventilator of  claim 14 , wherein said suction duct and discharge duct are crossed each other at least one point.  
   
   
       16 . The ventilator of  claim 14 , wherein said fan is a centrifugal fan, and said duct having the centrifugal fan is vertically crossed with respect to another neighboring duct, thereby decreasing a resistance in the flow of air from the centrifugal fan.  
   
   
       17 . The ventilator of  claim 14 , wherein a horizontal cross section of the total heat exchanger at a certain height are the same size formed in rectangular shapes.  
   
   
       18 . The ventilator of  claim 14 , wherein said total heat exchanger includes a plurality of channels that are stacked from top to bottom order, and the air flows therein in a straight line direction.  
   
   
       19 . A ventilator, comprising: 
 a casing;    a total heat exchanger that is provided in the interior of the casing and is extended in a horizontal direction and has a plurality of channels that are stacked in a vertical direction; and    a duct that connects the total heat exchanger and an outer portion of the casing.    
   
   
       20 . The ventilator of  claim 19 , further comprising: 
 a plurality of wrinkled plates that divide the channels in horizontal directions.
