Jet washer glass of the vehicle
(57) Abstract:Usage: the invention relates to a device for cleaning the windshields of vehicles. The invention allows more effective cleaning of the windscreen at low ambient temperatures. The essence of the invention: jet windshield washer spray washer fluid is carried out through two nozzles that are mounted in the body of the jet, and the jet is equipped with a heater connected to the nozzles and heating them. The technical effect of the invention is the ability to freeze the liquid, frozen to the windshield at low ambient air temperature up to -15oC. 1 Il. The invention relates to a device for cleaning glasses of vehicles.Famous jet washer glass of a vehicle, comprising a housing, at least one duzu, is connected by a pipe with the supply system washer fluid and a heating element associated with duty.In the known device converting electric energy into thermal energy is produced by the electrical resistance of the conductor current type thermistor, the efficiency of which the body and dusa removed from the heating element, and the sharp edge nozzles, spray jet, significantly affects the washing of the glass of the vehicle, additionally, the device selected for the prototype, does not solve the problem of workability clean the glass of the vehicle when the outside temperature is below -5oC.The disadvantage of this purifier is the technological complexity of manufacturing, a large number of elements, the locking spray nozzles ice, after cessation washer fluid, which makes it impossible in connection with this re-flow of the liquid.The aim of the invention is the preservation of the health system clean the glass of the vehicle when the outside temperature is below 0oC.The objective is achieved by the fact that the jet washer glass of a vehicle includes a housing, at least one duzu, is connected by a pipe with the supply system washer fluid and a heating element associated with duty equipped with another duty installed in the housing in a horizontal plane at an angle of 45oto the first dose, the outlet openings of the housing nozzles, made in the form of a cone with an angle of 50oand the surface washed CT glass.The location of the nozzles in the claimed jet in the horizontal plane at an angle of 45oone with respect to another is determined by the need to ensure liquid stains on washed surfaces.The optimal value of the angle is confirmed by experimental tests and complies with the specifications of the manufacturers of vehicles.In the inventive device nozzles placed in the enclosure in the holes made in the form of a cone with an angle of 50oand the surface of the housing facing the washed glass, tilted relative to the vertical axis at an angle of 15oaside from the washed glass.The choice of angle 50oand 15odetermined from the maximum allowable tilt angles when the vehicle is on an inclined surface approximately 15-20othe liquid remaining at the end of the nozzles, fills the entire volume of the nozzle and, in connection with distance from the heating element, there is a possibility of freezing of the liquid, which is unacceptable.The correct angles 50oand 15oconfirmed experimentally.At these angles is provided by removal of the fluid from the volume.The drawing shows of polymer material with the elements, preventing movement of the housing 1 in the body of the vehicle. In the housing 1 are mounted two nozzles 2 at an angle of 15oto the base, and the angle between the axes of the nozzles 45o. Outlet openings of the housing 1 are expanding cone angle 50o. Each dusa is a sphere, coupled with the cylinder and has a through hole for passage of washer fluid. The jet contains a heating sleeve 3, in contact on one side with conductive bus 4, and the other side with the heating element 5, which in turn is in contact with the bus bar 4 and the pipe 6 connecting the nozzle with the washer system.Jet works as follows.When the vehicle is in a system designed for washing, is always fluid. This fluid passes through the openings in the nozzles and, falling on the windshield, remove the dirt. At low ambient temperature below 0oC observe the formation of ice in the walk-through cross-sections of the nozzles.To eliminate this phenomenon in the proposed design jet has a heating element 5, through comprobadas bus 4 is the voltage of 12V from the power supply is correspondingly washer fluid.The tests have demonstrated the operability of the claimed device. When this jet washer glass of the vehicle can be installed on any vehicle, without change of energy, due to the small power consumption, requiring only the installation of additional keys enable or combining it with the power key of tocobaga rear window.The technical effect of the invention is that the health system washer glass of the vehicle is maintained until the ambient temperature -15oC. Jet washer glass of a vehicle, comprising a housing, at least one duzu, is connected by a pipe with the supply system washer fluid, and a heating element associated with duty, characterized in that it has another duty installed in the housing in a horizontal plane at an angle of 45oto the first dose, the outlet openings of the housing nozzles, made in the form of a cone with an angle of 50oand the surface of the housing facing the washed glass, tilted relative to the vertical axis at an angle of 15oaside from the washed glass.
SUBSTANCE: invention relates to onboard optical sensor assemblies. Onboard optical sensor case comprises holder 7, washer jet 9 and heater assembly. Holder is designed to retain optical sensor 3 with lens 5. Jet serves to wash sensor lens surface 5a or that of glass cover facing lens 5 by spraying washing fluid fed from 15 on lens or glass surface. Heater assembly comprises optical heater and jet heater. Optical heater and jet heater are made up of single part and integrated into one heater.Onboard optical heater comprises aforesaid case and optical sensor.
EFFECT: cleaning sensor case of sticking foreign particles.

SUBSTANCE: wiper brush consists of moving rocker (6) secured to brush body (1) by moving assemblies arranged at brush ends. Axle is arranged on one side of body end while brackets are arranged in symmetry on opposite end to support rod extending via bore of the sleeve secured at rocker (6). Sprayers connected by tube (4) are arranged in said body (1). In brush motion over the glass, body (1) turns on axle and rod displaces in said sleeve to make it thrust against the bracket of rocker (6). Note here that said sprayers displace to the zone ahead of elastic scraper (13) to spray the fluid on glass whereon said brush moves.
EFFECT: higher efficiency of cleaning.
