Abstract
A wiping and spraying apparatus is provided for wiping away dirty articles such as dead insects caked on the surface of a windshield of an automobile. The apparatus includes a wiper blade with adjustable depression force as well as first and second reservoirs of cleaning fluid. A valve is fluidly connected with the reservoirs to selectively allow either of the fluids to be sprayed onto the windshield. The apparatus further includes a control unit to operate the apparatus by automatically operating spraying and wiping, including adjustment of the depression force, according to two modes of operation.
Claims6
An automotive wiper apparatus comprising:
- means for wiping a surface of an object employed in an automobile, said means for wiping including at least one wiper blade having an adjustable depression force;
- means for jetting a first cleaning fluid and a second cleaning fluid onto the surface of said object;
- means for controlling both the wiping means and the jetting means under two modes of operation such that in a first mode of operation, said jetting means sprays the first cleaning fluid onto the surface of said object and said wiper blade is applied to said surface in a wiping motion under a first depression force;
- and wherein under a second mode of operation, said cleaning fluid onto the surface of said object over a predetermined time period, and said wiper blade to be applied to said surface in a wiping motion under a second depression force which is less than said first depression force.

- means for controlling both the wiping means and the jetting means under two modes of operation such that in a first mode of operation said jetting means sprays the first cleaning fluid onto the surface of said object and said wiper blade is applied to said surface in a wiping motion under a first depression force which is sufficient to substantially remove said jetted cleaning fluid after a few wipes;
- and
- wherein under a second mode of operation, said controlling means causes said jetting means to spray the second cleaning fluid onto the surface of said object, and said wiper blade to be applied to said surface in a wiping motion under a second depression force which is less than said first depression force, thereby causing said second cleaning fluid to be spread onto said surface to form a layer of cleaning fluid thereon;
- said controlling means further causing said wiper blade in said second mode of operation to be applied to said surface in a wiping motion under said first depression force after a predetermined period of time sufficient to allow articles of dirt to dislodge.
