Abstract

A portable generator includes a CO sensor module to sense CO levels in the environment surrounding the portable generator. The CO sensor module senses high levels of CO and sends a signal to shut down the engine on the portable generator. The CO sensor module alerts the user by emitting an LED light whether the CO sensor module is functioning properly, improperly or if high CO levels are detected. The CO sensor module is removable from a control panel of the portable generator to be replaced or maintained by the user per a replacement or maintenance schedule.

First claim

What is claimed is:

1. A generator comprising:
an engine;
a control panel comprising:
a control plate having a control surface and a back side positioned opposite from the control surface; and
a compartment coupled to the control plate, the compartment and the control plate defining an interior volume; and

a carbon monoxide (CO) sensor module including a CO sensor, the CO sensor module positioned to extend through the control plate and into the interior volume of the compartment and removably coupled to the back side of the control plate;
wherein the CO sensor module is configured to be removable from the control plate and replaceable with a replacement CO sensor module;
wherein the CO sensor is configured to detect CO concentration near the generator.

2. The generator of claim 1 , wherein the CO sensor module includes a housing having a first portion and a second portion, the first portion configured to be inserted into the interior volume of the compartment and the second portion configured to be positioned outside of the interior volume.

3. The generator of claim 2 , wherein the first portion of the housing includes a projection extending therefrom and the second portion of the housing includes a mounting ring configured to abut the control surface of the control plate.

4. The generator of claim 3 , wherein the control plate includes an opening formed in the control surface configured to receive the first portion of the CO sensor module and a recess formed in the opening configured to align with and receive the projection of the first portion upon installation of the CO sensor module into the opening.

5. The generator of claim 4 , wherein the CO sensor module is rotatable between an unlocked position and a locked position.

6. The generator of claim 5 , wherein in the locked position, the mounting ring abuts the control surface and the projection of the housing is not aligned with the recess.

7. The generator of claim 5 , wherein in the unlocked position, the projection of the housing is aligned with the recess.

8. The generator of claim 1 , wherein the CO sensor module includes a module wire harness configured to couple to an engine wire harness on the engine.

9. The generator of claim 8 , wherein when the module wire harness is coupled to the engine wire harness, the engine can start, and when the module wire harness is decoupled from the engine wire harness, an ignition of the engine is grounded and the engine cannot start.

10. The generator of claim 1 , wherein the CO sensor module includes a module battery providing power to the CO sensor module.

11. The generator of claim 10 , wherein the CO sensor module further comprises a light-emitting diode (LED) light configured as a visual indicator to alert a user of at least one of a life of the module battery is degrading, the CO sensor is degrading, and the CO sensor module is malfunctioning.

12. The generator of claim 1 , wherein the CO sensor is positioned within the housing of the CO sensor module and within the interior volume of the control panel.
