Problems solved by technology

[0004] However, the structure disclosed in the above-mentioned Patent Document 1 is a structure in which the cooling exhaust air of the engine body and the cooling exhaust air of the generator are guided to the exhaust muffler and blown directly thereto. Therefore, the cooling efficiency is not high, and when the exhaust air When the capacity of the muffler increases, the influence of high heat from the exhaust muffler on other components increases, and it is also difficult to deal with the diffusion direction of the cooling air that becomes high temperature due to cooling the exhaust muffler.

Abstract

The invention provides a motor-generator for improving the cooling efficiency of the exhaust silencer, reducing the influence to the other parts owing to the high heat from the exhaust silencer and setting the exhausting direction of the exhaust silencer to a defined direction so as to ensure the setting space easily. The exhaust silencer is arranged at top of one side of the generator. A conduitcomprises: a partition board portion for separating the exhaust silencer and the generator; a base board portion extending from the lower terminal of the partition board portion relative to the reversed side of the generator; a top board portion covering the exhaust silencer from the upside; and a terminal board portion connecting the terminals of the partition board portion, the base board portion and the top board portion relative to the reversed side of the generator main body. A silencer holding room is formed in the conduit. A cooling air inlet at the motor side for introducing the cooling air from the motor main body and a cooling air inlet at the generator side for introducing the cooling air from the generator are formed at the terminal portion at the motor main body side of the silencer holding room.

Description

technical field [0001] The present invention relates to an engine generator in which an engine main body of an engine having an exhaust muffler and a generator driven by the engine are mounted on an open frame. Background technique [0002] In the engine generator in which the engine main body of the engine and the generator driven by the engine are mounted on an open frame, since the surroundings of the engine and the generator are open structures, it is relatively easy to cool the high-temperature part, and there are also guide members A structure that guides the cooling exhaust air of the engine body and the cooling exhaust air of the generator to the exhaust muffler side to cool the exhaust muffler (for example, refer to Patent Document 1.). [0003] Patent Document 1: Japanese Patent Application Laid-Open No. 7-312846. [0004] However, the structure disclosed in the above-mentioned Patent Document 1 is a structure in which the cooling exhaust air of the engine body an...
