Abstract
A floor care apparatus includes a housing carrying a suction generator, a dirt collection vessel and an electroluminescent light source.
Description
- The present invention relates generally to the floor care equipment field and, more particularly, to a floor care apparatus equipped with an electroluminescent light source.
- A vacuum cleaner is an electro-mechanical appliance utilized to effect the dry removal of dust, dirt and other small debris from carpets, rugs, fabrics or other surfaces in domestic, commercial and industrial environments. In order to achieve the desired dirt and dust removal, most vacuum cleaners incorporate a rotary agitator. The rotary agitator is provided to beat dirt and debris from the nap of the carpet or rug while a pressure drop or vacuum is used to force air entrained with this dirt and debris into the nozzle of the vacuum cleaner. The particulate laden air is then drawn into a dirt collection vessel. The air is then drawn through a filter before being directed through the motor of the suction generator to provide cooling. Finally, the air is filtered to remove any fine particles of carbon from the brushes of that motor or other dirt that might remain in the air-stream before being exhausted back into the environment.
- It has long been known to equip the nozzle assembly of a canister vacuum cleaner, upright vacuum cleaner or extractor with a headlight for illuminating the work area so as to allow the operator to more efficiently and effectively guide the vacuum cleaner during the cleaning operation. U.S. Pat. No. 2,208,523 to Coleman discloses an early vacuum cleaner equipped with a tubular incandescent lamp, reflector and lens in order to direct light over the work area. More recent advances in technology have led to efforts to further improve illumination of the work field in front of a floor cleaning apparatus. For example, U.S. Pat. No. 5,207,498 to Lawrence et al. discloses a vacuum cleaner headlight system incorporating a light pipe. U.S. Pat. No. 6,672,735 to Dilger et al. discloses a vacuum cleaner equipped with a lighting system comprising a plurality of ultra-bright light-emitting diodes.
- The present invention relates to a floor care apparatus equipped with a new and further improved lighting system that is economical to build while also allowing greater design flexibility and the positioning of a light source along the lower portion of the nozzle assembly adjacent the work field or surface area to be cleaned so that maximum illumination and benefit is achieved.
- In accordance with the purposes of the present invention as described herein, a floor care apparatus is provided comprising a housing, a suction generator carried on the housing and a dirt collection vessel carried on the housing. The housing is further equipped with an electroluminescent light source that is directed so as to illuminate a work area adjacent to the floor care apparatus. The electroluminescent light source may take the form of a flexible strip and that flexible strip may be held in a channel on the vacuum cleaner.
- Alternatively, the present invention may be described as a floor care apparatus comprising a housing including a nozzle assembly wherein a suction generator and a dirt collection vessel are both carried on that housing. Still further, the invention includes an electroluminescent light source carried on the nozzle assembly and directed so that it illuminates a work area adjacent the floor care apparatus.
- More specifically describing the invention the floor care apparatus includes a bumper carried on the nozzle assembly. The electroluminescent light source is mounted to the bumper. Typically, the bumper includes a channel and the electroluminescent light source is received in that channel. The bumper may be made from a resilient material and the electroluminescent light source may be a flexible strip.
- Still further describing the invention the dirt collection vessel may take the form of a dirt cup. That dirt cup may include a cylindrical sidewall, a tangentially directed inlet and an outlet in order to provide for cyclonic air-flow. Alternatively, the dirt collection vessel may take the form of a filter bag such as a standard vacuum cleaner bag.
- In addition, the nozzle assembly may include a suction inlet and a rotary agitator may be carried on the nozzle assembly adjacent the suction inlet. Still further, the housing may include a canister assembly. Typically, the dirt collection vessel is carried on the canister assembly. In one possible embodiment, the canister assembly is pivotably connected to the nozzle assembly.
- In accordance with yet another aspect of the present invention a method is provided for illuminating the work area on a floor in front of a floor care apparatus. The method comprises the equipping of the floor care apparatus with an electroluminescent light source. More specifically describing the method, the method may include the positioning of the electroluminescent light source on a nozzle assembly of the floor care apparatus. Still further, the method may include the mounting of the electroluminescent light source on a bumper secured to the nozzle assembly of the floor care apparatus.
- In the following description there is shown and described several preferred embodiments of this invention, simply by way of illustration of one of the modes best suited to carry out the invention. As it will be realized, the invention is capable of other different embodiments and several details are capable of modification in various, obvious aspects all without departing from the invention.
