Abstract

A standby generator includes an engine including an output shaft, an alternator, and an enclosure including a base and a number of walls extending from the base including a front wall, a rear wall, a left wall, and a right wall. The output shaft extends toward the alternator and the left wall. The standby generator includes an intake opening configured to allow air to be drawn into the enclosure and an exhaust opening configured to allow heated air and exhaust gases to be expelled from the enclosure. The intake opening is provided on the rear wall and the exhaust opening is provided on the front wall.

First claim

What is claimed is:

1. A standby generator, comprising: an engine including an output shaft;
an alternator; an enclosure comprising: a base; and
a plurality of walls extending from the base comprising a front wall, a rear wall, a left wall, and a right wall, wherein the output shaft of the engine extends toward the alternator and the left wall;
a first intake opening configured to allow air to be drawn into the enclosure proximate the engine; and
an exhaust opening configured to allow heated air and exhaust gases to be expelled from the enclosure;
wherein the first intake opening is provided on the rear wall proximate the right wall and the exhaust opening is provided on the front wall proximate the left wall;
wherein the air drawn into the enclosure at the first intake opening directly flows over the engine and is expelled through the exhaust opening.

2. The standby generator of claim 1 , further comprising a cover coupled to the rear wall, wherein the cover comprises an upper surface that is not parallel to the base when the cover is in a closed position.

3. The standby generator of claim 1 , further comprising:
a second intake opening provided on the rear wall configured to allow air to be drawn into the enclosure.

4. The standby generator of claim 3 , wherein the first intake opening is configured to allow air to be drawn into the engine and wherein the second intake opening is configured to allow air to be drawn into the enclosure to cool the alternator.

5. The standby generator of claim 4 , wherein the first intake opening and the second intake opening are positioned on opposite sides of the rear wall.

6. The standby generator of claim 4 , wherein the second intake opening is positioned proximate the left wall.

7. The standby generator of claim 4 , wherein the first intake opening and the second intake opening draw air into the enclosure in the same direction as an expulsion of exhaust gases from the exhaust opening.

8. The standby generator of claim 4 , further comprising:
an engine intake duct configured to route air entering the first intake opening to the engine;
an alternator intake duct configured to route air entering the second intake opening to the alternator; and
a muffler exhaust duct configured to route exhaust gases from the engine to the exhaust opening.

9. A standby generator, comprising:
an engine including an output shaft;
an alternator;
a base;
a first pair of opposing walls coupled to the base comprising:
a front wall; and
a rear wall;

a second pair of opposing walls coupled to the base comprising:
a left wall, wherein the output shaft of the engine extends toward the alternator and the left wall; and
a right wall;

a first intake opening positioned in the rear wall proximate the right wall configured to draw air into the generator proximate the engine; and
an exhaust opening positioned in the front wall proximate the left wall configured to expel exhaust gases and heated air from the generator;
wherein air drawn into the enclosure at the first intake opening directly flows over the engine and is expelled through the exhaust opening.

10. The standby generator of claim 9 , further comprising a cover coupled to the rear wall, wherein the cover comprises an upper surface that is not parallel to the base when the cover is in a closed position.

11. The standby generator of claim 9 , wherein the second pair of opposing walls does not include the first intake opening or the exhaust opening.

12. The standby generator of claim 11 , further comprising a second intake opening positioned in the rear wall configured to draw air into the generator.

13. The standby generator of claim 12 , wherein the first intake opening is configured to draw air into the generator to cool the engine and wherein the second intake opening is configured to draw air into generator to cool the alternator.

14. The standby generator of claim 13 , wherein the first intake opening and the second intake opening are positioned on opposite sides of the rear wall.

15. The standby generator of claim 14 , wherein the first intake opening and the second intake opening draw air into the enclosure in the same direction as an expulsion of exhaust gases from the exhaust opening.

16. The standby generator of claim 15 , further comprising:
an engine intake duct configured to route air entering the first intake opening to the engine;
an alternator intake duct configured to route air entering the second intake opening to the alternator; and
a muffler exhaust duct configured to route exhaust gases from the engine to the exhaust opening.

17. The standby generator of claim 15 , wherein the engine intake duct comprises a 90-degree turn to air flow between the first intake opening and the engine.

18. The standby generator of claim 15 , wherein the alternator intake duct comprises a 90-degree turn to air flow between the second intake opening and the alternator.

19. The standby generator of claim 15 , wherein the muffler exhaust duct comprises a 90-degree turn to air flow between the engine and the exhaust opening.
