PUMPED DRAIN AND DEFROST WINDSHIELD WIPER SYSTEM
A windshield wiper including: a housing including a blade mounted therein; at least one drain tube including a plurality of inlets; and a coupler for coupling the at least one drain tube to a pump. A system incorporating the windshield wiper and vehicles having the system installed are disclosed.
1 . A windshield wiper comprising:
a housing comprising a blade mounted therein;
at least one drain tube comprising a plurality of inlets; and
a coupler for coupling the at least one drain tube to tubing that leads to a pump, wherein the pump is configured for pumping precipitation from the windshield during a variety of inclement weather conditions.
2 . The windshield wiper as in claim 1 , further comprising at least one heater for providing heat within the housing.
3 . The windshield wiper as in claim 2 , wherein the heater comprises at least one of a resistive heater and a forced hot air heater.
4 . The windshield wiper as in claim 1 , wherein the housing comprises a cross section that is one of an inverted U shape and an inverted V shape.
5 . The windshield wiper as in claim 1 , wherein the at least one drain tube is disposed parallel to and along a length of the blade.
6 . The windshield wiper as in claim 1 , further comprising at least one grommet disposed on a sidewall of the housing.
7 . The windshield wiper as in claim 6 , wherein the at least one grommet is segmented along a length of the housing.
8 . The windshield wiper as in claim 1 , wherein a mount for retaining the blade comprises one of a suspension system and at least one mount coupled to the housing.
9 . A system for wiping a windshield, the system comprising:
at least one windshield wiper comprising a housing with a blade mounted therein;
at least one drain tube comprising a plurality of inlets; and a coupler for coupling the at least one drain tube to tubing that leads to a pump; and
a pump for applying a negative pressure to the at least one drain tube and pumping inclement weather precipitation from the windshield.
10 . The system as in claim 9 , further comprising at least one heater for heating the precipitation.
11 . The system as in claim 10 , wherein the heater comprises at least one of a resistive heater and a forced hot air heater.
12 . The system as in claim 10 , further comprising a controller for controlling at least one of a rate of pumping, the heating and a speed of wiping.
13 . The system as in claim 12 , further comprising at least one of a rain sensor and a temperature sensor, each sensor adapted for providing input to the controller.
14 . The system as in claim 9 , adapted for operating a first one of the at least one windshield wipers independently of another windshield wiper.
15 . The system as in claim 9 further comprising another pump for applying the negative pressure.
16 . The system as in claim 9 , wherein the pump may be reversed for supplying windshield wash to the at least one drain tube.
17 . A vehicle comprising a system for wiping a windshield, the vehicle comprising:
a windshield; and
at least one windshield wiper comprising a housing with a blade mounted therein;
at least one drain tube comprising a plurality of inlets; and a coupler for coupling the at least one drain tube to tubing that leads to a pump; and a pump for applying a negative pressure to the at least one drain tube and pumping precipitation from the windshield;
wherein the at least one windshield wiper is mounted to the vehicle for providing wiping of precipitation from the windshield during operation of the vehicle.
18 . The vehicle as in claim 17 comprising one of an automobile, a truck, a train, an airplane and a boat.
