Ventilation device

Abstract

A ventilation device performs ventilation by supplying outdoor air indoors as supply air and exhausting room air outdoors as exhaust air. The ventilation device includes a heat exchange unit provided with a heat exchange element that performs heat exchange between the supply air and the exhaust air and a humidification unit provided with a humidification element that humidifies the supply air. The heat exchange unit is provided with a supply air blower with which the outdoor air is suctioned and sent to the humidification unit and a supply air delivery port with which supply air sent from the supply air blower is delivered and guided to the humidification unit. The humidification unit is provided with a supply air introduction port that introduces supply air delivered from the heat exchange unit, and a supply air duct that regulates spreading of supply air introduced from the supply air introduction port.

1 . A ventilation device that performs ventilation by supplying outdoor air indoors as supply air and exhausting room air outdoors as exhaust air, comprising:
 a heat exchange unit provided with a heat exchange element that performs heat exchange between the supply air and the exhaust air; and   a humidification unit provided with a humidification element that humidifies the supply air,   the heat exchange unit being provided with: a supply air blower with which the outdoor air is suctioned and sent to the humidification unit; and a supply air delivery port with which supply air sent from the supply air blower is delivered and guided to the humidification unit, and   the humidification unit being provided with: a supply air introduction port that introduces supply air delivered from the heat exchange unit; and a supply air duct that regulates spreading of supply air introduced from the supply air introduction port.   
     
     
         2 . The ventilation device according to  claim 1 , wherein a sealing member by which a section of connecting the supply air delivery port and the supply air introduction port is encompassed to implement sealing between the heat exchange unit and the humidification unit is provided between the heat exchange unit and the humidification unit. 
     
     
         3 . The ventilation device according to  claim 1 , wherein the supply air delivery port of the heat exchange unit is provided with a guide that guides supply air sent from the supply air blower toward the humidification element of the humidification unit. 
     
     
         4 . The ventilation device according to  claim 3 , wherein the guide includes a curved bottom surface arranged along an inner circumferential surface of the supply air delivery port and arranged along an inner surface at a supply air flow section of the supply air duct, and an inclined upper surface. 
     
     
         5 . The ventilation device according to  claim 2 , wherein the supply air delivery port of the heat exchange unit is provided with a guide that guides supply air sent from the supply air blower toward the humidification element of the humidification unit. 
     
     
         6 . The ventilation device according to  claim 5 , wherein the guide includes a curved bottom surface arranged along an inner circumferential surface of the supply air delivery port and arranged along an inner surface at a supply air flow section of the supply air duct, and an inclined upper surface.
