Outdoor power generating apparatus

Abstract

An outdoor power generating apparatus includes a housing including a generator chamber and a side wall portion, a power generation source configured with an engine-type generator or a fuel cell, a ventilation fan, and an exhaust passage provided within the housing and through which a gas within the generator chamber is exhausted to an outside of the housing as an exhaust gas, wherein the exhaust passage includes a sound absorbing duct formed by a sound absorbing material used for a curved passage, a weir member, a weir passage, a diversion passage changing the flow direction of the exhaust gas so as to be orthogonal to a direction along which the exhaust gas flows towards the weir passage from the curved passage, and an exhaust port provided at an end portion of the diversion passage and opening at the side wall portion so as to be exposed to an ambient air.

         7 . An outdoor power generating apparatus comprising:
 a housing including a generator chamber and a side wall portion;   a power generation source configured with an engine-type generator or a fuel cell provided within the generator chamber of the housing;   a ventilation fan provided within the housing; and   an exhaust passage provided within the housing and through which a gas remaining within the generator chamber is exhausted to an outside of the housing as an exhaust gas, wherein   the exhaust passage includes a sound absorbing duct formed by a sound absorbing material used for forming a curved passage, which is connected to the generator chamber so as to be in a communication with the generator chamber and extends so as to curve, a weir member provided at a downstream side of the sound absorbing duct in a flow direction of the exhaust gas and including an inclined portion, a weir passage defined by the weir member and a weir frame, a diversion passage connected to the weir passage so as to be in a communication with the weir passage, and an exhaust port provided at an end portion of the diversion passage and opening at the side wall portion of the housing so as to be exposed to an ambient air,   the exhaust gas flowing at a downstream side relative to the weir passage in the flow direction is guided to flow in a different direction from a flow direction along which the exhaust gas flows except for the downstream side of the weir passage by means of the inclined portion, and   the exhaust gas passing through the weir passage is guided by the diversion passage so that the flow direction of the exhaust gas is changed to a direction orthogonal to the flow direction along which the exhaust gas flows from an outlet opening of the curved passage towards the weir passage.   
     
     
         8 . The outdoor power generating apparatus according to  claim 7 , wherein the sound absorbing material has a hydrophilicity or a water repellency on a surface of the sound absorbing material exposed to the curved passage.
