Ventilator

Abstract

A ventilator including a case having a supply air port to introduce outdoor air and an exhaust air port to discharge indoor air, a supply and exhaust air duct to communicate with the supply air port and the exhaust air port, and a partition disposed in the supply and exhaust air duct to divide the supply and exhaust air duct into a supply air region to communicate with the supply air port and an exhaust air region to communicate with the exhaust air port, the partition having protrusions protruding outward from opposite ends of the supply and exhaust air duct, the protrusions being bent. The partition is easily inserted into the supply and exhaust air duct by the bent protrusions of the partition to prevent leakage of indoor air and outdoor air and thus prevents the outdoor air and the indoor air from being mixed.

         4 . The ventilator according to  claim 3 , wherein the supply air port and the exhaust air port communicate with each other at one end of the supply and exhaust air duct. 
     
     
         5 . The ventilator according to  claim 4 , further comprising:
 a hood cap connected to the supply and exhaust air duct at an end opposite to the end where the supply air port and the exhaust air port communicate with each other, wherein   the hood cap is provided with a hood cap partition to divide the hood cap into a supply air region to communicate with the supply air region of the supply and exhaust air duct and an exhaust air region to communicate with the exhaust air region of the supply and exhaust air duct.   
     
     
         6 . The ventilator according to  claim 5 , wherein one of the protrusions contacts an inside of the supply air port and/or an inside of the exhaust air port, and the other protrusion contacts the hood cap partition. 
     
     
         7 . The ventilator according to  claim 6 , wherein the protrusions of the partition are bent. 
     
     
         8 . The ventilator according to  claim 7 , wherein the foam member is attached to at least one surface of the partition contacting the supply air port and the hood cap partition. 
     
     
         9 . The ventilator according to  claim 5 , wherein one of the protrusions is disposed in a first groove formed between the supply air port and the exhaust air port, and the other protrusion is disposed in a second groove formed at the hood cap partition. 
     
     
         10 . The ventilator according to  claim 2 , wherein the case has an indoor supply air port to introduce indoor air and an indoor exhaust air port to discharge outdoor air. 
     
     
         11 . The ventilator according to  claim 10 , further comprising:
 a supply air unit to guide the outdoor air introduced through the supply air port into a room;   an exhaust air unit to guide the indoor air introduced through the indoor supply air port out of the room; and   a total heat exchanger to perform total heat exchange between the outdoor air and the indoor air guided by the supply air unit and the exhaust air unit.   
     
     
         12 . A ventilator comprising:
 a case having an outdoor supply air port to introduce outdoor air, an indoor supply air port to introduce indoor air, an indoor exhaust air port to discharge indoor air, and an outdoor exhaust air port to discharge outdoor air;   a supply air unit to guide the outdoor air introduced through the outdoor supply air port to the indoor exhaust air port;   an exhaust air unit to guide the indoor air introduced through the indoor supply air port to the outdoor exhaust air port;   a total heat exchanger to perform total heat exchange between the outdoor air and the indoor air guided by the supply air unit and the exhaust air unit;   a supply and exhaust air duct to communicate with the outdoor supply air port and the outdoor exhaust air port;   a partition disposed in the supply and exhaust air duct to divide an interior of the supply and exhaust air duct into a supply air region to communicate with the outdoor supply air port and an exhaust air region to communicate with the outdoor exhaust air port; and   a hood cap connected to the supply and exhaust air duct such that the hood cap communicates with the supply air region and the exhaust air region, wherein   the partition has protrusions protruding outward from opposite ends of the supply and exhaust air duct, the protrusions being bent to contact the outdoor supply air port and the hood cap.   
     
     
         13 . The ventilator according to  claim 12 , wherein the partition has a foam member attached to a surface thereof. 
     
     
         14 . A ventilator comprising:
 a case having an outdoor supply air port to introduce outdoor air and an outdoor exhaust air port to discharge indoor air;   a supply and exhaust air duct to communicate with the outdoor supply air port and the outdoor exhaust air port, the supply and exhaust air duct being divided into a first supply air region to communicate with the outdoor supply air port and a first exhaust air region to communicate with the outdoor exhaust air port by a first partition disposed in the supply and exhaust air duct; and   a hood cap connected to the supply and exhaust air duct, the hood cap being disposed outdoors, the hood cap being divided into a second supply air region to communicate with the first supply air region and a second exhaust air region to communicate with the first exhaust air region by a second partition, wherein   the first partition has protrusions protruding outward from opposite ends of the supply and exhaust air duct to contact the outdoor supply air port and the second partition.
