Abstract

In a generator including an engine, an inverter, and a cooling fan inside an exterior body, an air intake port is provided on a predetermined cover constituting a part of the exterior body. The air intake port aggregates each cooling air inlet of the generator, and the inverter is provided at a position where cooling air makes direct contact, the cooling air flowing in from the air intake port by the cooling fan, and the position corresponding to a position between the engine and the air intake port.

Claims (30)

1. A generator comprising an engine, an inverter, and a cooling fan inside an exterior body, wherein

a cooling air inlet of the generator is an air intake port,

the air intake port is provided on a predetermined cover constituting a part of the exterior body,

the inverter is provided at a position where cooling air makes direct contact, the cooling air flowing in from the air intake port by the cooling fan, and the position corresponding to a position between the engine and the air intake port,

the air intake port is provided with:

an eaves part that contacts the inverter and that covers above the inverter; and

a bridging member that is extending in an up-down direction and toward the inverter, wherein

an air guiding part is provided between the bridging member and the inverter, and

the air guiding part is in a labyrinth shape.

2. The generator according to claim 1 , wherein

the air guiding part is provided on the predetermined cover

the air guiding part guides the cooling air of the air intake port to a surrounding of the inverter, and has a boundary configuration part constituting a boundary of the air intake port, and

the boundary configuration part serves both as a fastening part for fastening the inverter and at least a part of the air guiding part.

3. The generator according to claim 1 , comprising:

a control panel case on a back side of the predetermined cover, the control panel case for covering at least a part of a control panel, wherein

the eaves part is provided on the control panel case.

4. The generator according to claim 1 , wherein

another opening part is provided on a region in the predetermined cover, the region excluding the air intake port, and

a predetermined component is arranged within the exterior body, the predetermined component freely extracted through the another opening part, and the predetermined component being an exchange target or a maintenance target.

5. The generator according to claim 4 , wherein

the inverter is arranged in a vertical placement posture in which a length of an up-down direction is longest.

6. The generator according to claim 4 , wherein

the predetermined component is a battery.

7. The generator according to claim 4 , wherein

a lid member is freely attachably and detachably provided on the predetermined cover, the lid member for covering the air intake port and the another opening part by a louver.

8. The generator according claim 1 , wherein

the predetermined cover is a front cover for covering a front surface of the exterior body,

a control panel is arranged on a back side of the front cover, the control panel being higher than the air intake port,

a control panel case is arranged on a back side of the front cover, the control panel case for covering the control panel from a back surface side, and

a part of the control panel case is formed in a recessed shape toward the front cover side, and by having an upper part of the inverter positioned on a region with the recessed shape, the upper part of the inverter is arranged at a position in a horizontal direction of the generator, the position overlapping with a part of the control panel, and the part of the control panel case becomes the eaves part.
