Heated jet windshield washer car
(57) Abstract:Usage: heated washer jets windscreen (windshield and rear glass of the car used in the cold time of the year to maintain the system washer glass by heating the air space under sub-genres water guiding element. The inventive heated jet windshield washer car contains a plastic case, the installed plastic power fitting, spiral wire resistor ends for connection to the power supply system and at least one sub-genres water guiding element with a through hole. Different jet that between the fitting and sub-genres water guiding element in the direction of movement of water in a metal tube, the input and output parts which are recessed in the corresponding in diameter annular slots, Subarus are made in the body and fitting. Wire wound resistor on top of the middle part of the metal tube, its coils located in the air cavity of the housing, which also missed with diametrically opposite sides of the tube ends of the resistor. To the last attached going from house p sub-genres water guiding element is provided by a conical socket, accompanied by a large diameter with a corresponding annular slot. Sub-genres water guiding element is placed in the channel of the housing, extracted from the tapered socket, and made in the form of a metal ball mounted with a tight fit so that the axis of the through hole intersects the axis of the conical socket. Each support platform fitting has opposite sides spaced slots, and the corresponding plate electrocontact made with a cruciform shape, the elements of which are included in the return grooves foothold. The ends of the resistor attached to the respective plate to the electrical contacts by soldering. 3 C. p. F.-ly. 3 Il. The invention relates to vehicles and concerns heated washer nozzles the windshields of vehicles used for preheating the most active freezing in the cold season parts washer.Known windshield washer car containing a heated brush having a cavity with a heating element that is moved together with brushes and connected to a nozzle that is moved together with the brush. This design provides simultaneous heating of brushes and rolling jet, but is not intended for heating giclee windscreen of the car, containing flexible heated hose, made of a plastic heat-resistant conductive film, forming a heated channel for the passage of fluid supplied to the washer nozzles. This design allows you to heat the applied liquid, but is not intended for direct heating of the nozzles, Pat. Germany N 4026254, B 60 S 1/48, 1991.Known windshield washer vehicle containing the system heated water conveyance pipes, nozzles, heated sub-genres water guiding balls, spiral heaters wound around the injectors connected in serial electrical circuit. This design allows heat pipes, nozzles, water tank, but complicated by the scheme, and if the open circuit of one of the heaters may damage the system as a whole, a useful model of the Russian Federation No. 923, B 60 S 1/46, 1994.Known heated jet, the windshield of a motor vehicle comprising a plastic housing and sub-genres water guiding element in the form of a metal ball with a through hole, the housing has a power socket is made integral unit with the housing, and a ball covered two heating elements located NR the Clair, but not suitable for replacement of the heating elements due to its nerazborite, Pat. Germany N 3124112, B 60 S 1/46, 1982.The closest in design and functionality is heated jet, the windshield of a motor vehicle comprising a plastic body, the installed plastic power fitting, spiral wire resistor, the ends of which are intended for connection to the power supply system of the vehicle, and mounted in the housing at least one sub-genres water guiding element with a through hole. This design provides heating of the jet due to the heat from the resistor, but not suitable to replace the resistor, since it is a cast polymer construction, mounted in a bearing metal case; the wire ends of the resistor out of the case and is not protected in places subsequent connections, Pat. UK N 2044601, B 60 S 1/46, 1980.The purpose of the invention to provide the possibility of replacing the resistors, protection of places of connection of the ends of the wire resistor with electrical contacts, obtaining the possibility to adjust the position of sub-genres water guiding element without damage to the resistor, the cleaning ability of the cavities of the jet.
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.
