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.

In Fig. 1 shows a General view of a heated nozzle in assembled condition; Fig. 2 depicts the Assembly unit (liner), which is a fitting carrying a metal tube with a wire resistor, the ends of which are connected to plate electrical contacts; Fig. 3 the same as in Fig. 2, in the section.

Heated jet windshield washer car contains plastic housing 1, the installed plastic power socket 2, the spiral wire resistor 3, the ends 4 and 5 which are intended for connection to the power supply system of the vehicle (not shown), and mounted in the housing 1 at least one sub-genres water guiding element 6 through Otway tube 8, the inlet 9 and outlet 10 of which are recessed in the corresponding in diameter annular slots 11 and 12, Subarus are made in the body 1 and the nozzle 2. In the housing 1 is made of an air cavity 13, and wire the resistor 3 is wound on top of the middle part 14 of the metal tube 8 and the spiral coils are located in the air cavity 13, in which there are also wire the ends 4 and 5 of the resistor with diametrically opposite sides of the metal tube 8. To the ends 4 and 5 of the resistor attached coming out of the housing 1 plate electrical contacts 15 and 16, is pressed against the inner wall 17 of the hollow support pads 18, made in the fitting 2. In the housing 1 from the side of the sub-genres water guiding element 6 is made conical socket 19, which is accompanied by a large diameter with a corresponding annular slot and sub-genres water guiding element 6 is installed in the channel 20 of the housing 1, paired with a tapered socket 19. Each sub-genres water guiding element 6 made in the form of a metal ball mounted on the tight fit in the channel 20 of the housing 1 so that the axis Of its through hole intersects the axis C-C of the conical socket 19. Each support platform 18 of the fitting 2 has opposite sides spaced grooves 21 and 22, and the corresponding plastipure site. Each end 4 and 5 of the resistor attached to the respective plate electrocontact soldering.

This design is detachable and allows for the failure of the resistor to replace it. Tapered socket 19 restricts the movement of the metal tube 8 and allows a needle to clean the hole sub-genres water guiding element 6 and adjust its position relative to the housing 1, not touching this spiral coils of the resistor. Razornet nozzle allows you to clean the inside of the cavity when the pollution. Closed air cavity 13 protects places solder plate electrical contacts with the ends of the resistor from moisture, and by accumulating in the cavity to heat the solder joints periodically dries.

The principle of operation of the heated nozzle is as follows. Submitting the voltage on the electrical contacts 15 and 16 are heated wire resistor 3, the heat which heats the metal tube 8, warming up as the air cavity under sub-genres water guiding element 6. Accordingly, heat is transferred sub-genres water guiding element 6, a through hole which is thus protected from freezing. The tube 8 may be made of copper or Allee interference for penetration of heat to the tube. A relatively large surface of the heating tube 8 allows to reduce electricity consumption; rated power of this design is to 0.72 watts. As the wire resistor used resistor type P2-88. Rated resistance is 200 Ohms. The resistance of the insulating coating is from 0.05 mω to 50 mω. Heated jet can have two sub-genres water guiding element. Reference sites nozzle holding plate electrical contacts and fix the fitting relative to the housing. The hood of the car or other elements of the body, the nozzle is mounted in a known manner through turned back retainers, performed on the body at the same time a whole with him. The location of the resistor in the middle part of the metal tube 8 allows you to heat almost only metal surface thereby eliminating loss on heating of the plastic housing, as opposite resistor air cavity 13 isolates the resistor directly from the walls of the housing 1.
