Jet washer glass of the vehicle
(57) Abstract: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. In the 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 heated bushing installed in the housing with contacting with one side of the current-carrying bus, and on the other hand - with a heating element made in the form of tablets, connected with the current-carrying bus. The technical effect of the invention is the ability to freeze the liquid, frozen to the windshield, lowering the ambient temperature 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, which has at least one dusa connected by a pipe with the supply system washer fluid, and a heating element with a current-carrying wire that is associated with duso the resistance of the conductor current type thermistor, Efficiency which is 3-4 times less than in the claimed device, which uses paratory element, a non-metallic housing and dusa removed from the heating element, and the sharp edge nozzles, spray jet, significantly affects the washing of the glass of the vehicle, in addition, 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.Object of the invention is the preservation of the health treatment system, window glass of the vehicle when the outside temperature is below 0oC.The technical result of the early invention is achieved by the fact that the jet washer glass of a vehicle, comprising a housing, which has at least one dusa connected by a pipe with the supply system washer fluid, and a heating element with the first plane at an angle of 45oto the first dose, and heating the sleeve is installed in the housing with contacting on one side with duty, and on the other hand - with a heating element made in the form of tablets, connected with the current-carrying bus, the outlet openings of the housing nozzles, made in the form of a cone with an angle of 55-65oand the surface of the housing facing the washed glass, tilted relative to the vertical axis at an angle of 25-30oaside from the washed glass, while on the upper part of the heated sleeve-applied thermal grease, to prevent the ingress of water on current-carrying bus, and a current-carrying wire is connected with the current-carrying bus, located in the braid and installed in the groove made in the pipe.The location of the nozzles in the claimed jet in the horizontal plane at an angle of 45orelative 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 the axis at an angle of 25-30oaway from the washed glass.The choice of angle 55-65oand 25-30odetermined 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 55-65oand 25-30oexperimentally, When these angles is provided by removal of the fluid from the volume.The drawing shows the device of the jet washer glass of the vehicle. The nozzle includes a housing 1 made of a polymeric material with elements that impede the movement of the body 1 in the body of the vehicle. In the housing 1 are mounted two nozzles 2 at an angle of 25-30oto the base, and the angle between the axes of the nozzles 45o. Outlet openings of the housing 1 are expanding cone angle 55-65o. Each dusa is a sphere, coupled with the cylinder and has a through hole for passage of washer fluid.The jet contains a heated sleeve 3 mounted in the housing is anonym in the form of tablets, which in turn is in contact with the current-carrying bus 4 connected with the current-carrying wire 6 and the pipe 7 connects the nozzle with the washer system.Jet works in the following way. 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 0oobserved ice formation in flow cross sections of the nozzles.To eliminate this phenomenon in the proposed design jet has a heating element 5, through which the current-carrying bus 4 and the current-carrying wire 6 is the voltage of 12V from the power supply of the vehicle. The heating element 5 transmits heat through a heated sleeve 3 of the nozzle 2, the holes are thawed washer fluid.To improve the health of the device and prevent the ingress of water on current-carrying bus 4 on the upper part of the heated sleeve 3 applied lubricant and to exclude Oblomov current-carrying wires 6 they made braided and placed in the groove of the socket 7.Conducted COI is and the vehicle can be installed on any motor vehicle, without changing the energy, due to the small power consumption, requiring only the installation of additional keys enable or combining it with key 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 -15o. Jet washer glass of a vehicle, comprising a housing, which has at least one dusa connected by a pipe with the supply system washer fluid, and a heating element with a current-carrying wire 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, and heating the sleeve is installed in the housing with contacting on one side with duty, and on the other hand - with a heating element made in the form of tablets, connected with the current-carrying bus, the outlet openings of the housing nozzles, made in the form of a cone with an angle of 55 to 65oand the surface of the housing facing the washed glass, tilted relative to the vertical axis at an angle of 25 - 30
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.
