Abstract

An irrigation unit (20) for irrigating an area (12) with a fluid (19) from a fluid source (18) includes a housing (200), a nozzle (220), one or more electronic components (221), and a unit control system (240). The nozzle (220) is secured to the housing (200) and the nozzle (220) is in fluid communication with the fluid source (18) so that fluid (19) from the fluid source (18) is transferred to the nozzle (220). The unit control system (240) can perform a self-test on the irrigation unit (20) to make sure that the irrigation unit (20) is functioning properly. Additionally, the irrigation unit (20) can include a cleaner (259u) that is coupled to the housing (200). The cleaner (259u) can clean one or more electronic components (221) that are part of the irrigation unit (20).

Claims

1. An irrigation unit for irrigating an area with a fluid from a fluid source, the irrigation unit comprising:

a housing;

a nozzle that is secured to the housing, the nozzle being in fluid communication with the fluid source so that fluid from the fluid source is transferred to the nozzle;

an electronic component coupled to the housing; and

a cleaner coupled to the housing that cleans a portion of the electronic component.

2. The irrigation unit of claim 1 wherein the electronic component includes a lens and the cleaner cleans the lens.

3. The irrigation unit of claim 1 wherein the electronic component includes a sensor and the cleaner cleans a portion of the sensor.

4. The irrigation unit of claim 1 wherein the cleaner directs a fluid at the electronic component to clean the electronic component.

5. The irrigation unit of claim 1 wherein the cleaner includes a cloth material and the electronic component is moved relative to the cloth material to clean the electronic component.

6. The irrigation unit of claim 5 wherein the cloth material is a chamois.

7. The irrigation unit of claim 1 wherein at least a portion of the electronic component includes a stick resistant coating.

8. The irrigation unit of claim 1 wherein the housing includes a first section that retains the electronic component and a second section that retains the cleaner, the first section and electronic component being moveable relative to the second section and the cleaner, wherein the cleaner cleans the electronic component during movement of the electronic component relative to the cleaner.

9. A method for irrigating an area with a fluid from a fluid source, the method comprising the steps of:

providing a housing;

securing a nozzle that to the housing, the nozzle being in fluid communication with the fluid source so that fluid from the fluid source is transferred to the nozzle;

coupling an electronic component to the housing; and

cleaning a portion of the electronic component with a cleaner coupled to the housing.

10. The method of claim 9 wherein the step of cleaning includes the step of directing a fluid at the electronic component to clean the electronic component.

11. The method of claim 9 wherein the step of cleaning includes the step of moving the electronic component relative to a cloth material to clean the electronic component.

12. The method of claim 9 further comprising the step of coating at least a portion of the electronic component includes a stick resistant coating.
