The heated nozzle (options)

 

(57) Abstract:

The invention relates to hydraulic devices for dispersion and the fluid used in the washer vehicles, in particular in vehicles, as well as in other areas of technology related to the application of such devices. The nozzle has a flat nozzle, formed by two converging at an angle to the planes and the two surfaces curved along the curve of the second order. Presents two options for performing these surfaces on the various elements of the nozzle: the body and the liner. This nozzle design creates the upper stream of sprayed liquid and the fuel element is designed as a semiconductor device in the integrated design schemes limiter current and temperature. The design of the heated nozzle allows its use in the operation of the transport at low temperatures, preventing the freezing of washer fluid in the nozzle and creating the possibility of defrosting frozen, for example, when Parking in the cold liquid. 2 S. and 2 C.p. f-crystals, 5 Il.

The invention relates to hydraulic devices for dispersion and the fluid used in the CX with the use of such devices.

Known devices [1], designed for spraying fluid and supply it to the surface to be cleaned, for example the windshield of the vehicle, and is equipped with heaters to prevent freezing of liquid in the nozzle or liquidating such freezing. In particular, the United Kingdom patent N 2044601 proposed injector from the intake channel, a coiled resistive heating element in the form of an elastic belt in an electrical circuit which includes a switch associated with thermostat. The disadvantages of this injector are, first, conical nozzle, giving the torch spray with circular symmetry, and, secondly, the presence of additional devices - thermostat with on / off switch.

It is also known device [2] for U.S. patent N 4212425, in which the heating element is used, the tablet material having a positive thermal coefficient of resistivity. This allows to maintain the desired temperature, but the spray nozzle head also gives the torch fluid only circular symmetry.

It is also known device [2] for U.S. patent N 4212425, in which the heating element is used, the tablet material the required temperature, but the spray nozzle head also gives the torch fluid only circular symmetry.

Also known nozzle (patent UK N 2062452 A MKI B 60 S 1/52) for a windshield wiper of the vehicle in which the liquid stream is first compressed in a narrowing channel, and then is expanded in a funnel-shaped flat output, dramatically extending in one plane and slightly - perpendicular. Thereby, the fan stream. The disadvantage of this design is the loss of energy flow during extension, and, most importantly, such a nozzle is not heated.

The essence of the invention lies in the fact that the nozzle is in the form of a housing in which is formed one of the converging planes, and a liner of heat-conductive material in which is formed a second converging plane surfaces curved along the curve of the second order. Between the liner and the casing there is a gap in which to insert the fuel element, such as a voltage stabilizer in the integrated design-plastic-type-220, which includes circuit current limit (up to 1 A) and temperature (up to 120oC). Another option of the same decision may be the case, which is Adis hugs strip of heat conducting material, for example, aluminum, which is in contact with the fuel element.

In Fig. 1 shows a longitudinal section of the nozzle, where 1 - nozzle, 2 - insert 3 - converging planes, the top of which is formed in the liner, and the lower housing, 4 - socket for input fluid, and 5 - fuel element.

In Fig. 2 shows the liner in three dimensions, the first of which POS. 1 shows a surface curved along the curve of the second order, forming together with converging planes 3 (Fig.1) flat nozzle.

In Fig. 3 shows another variant of the nozzle 1 is also the case that 2 is also a liner and 3 - strip of heat conducting material, 4 - fuel element. Converging plane in this case formed in the casing and the liner - POS. 1 (figs. 3). Surface curved along the curve of the second order, formed in the insert of Fig. 4.

In Fig. 5 shows a strip of heat conducting material, where the 1 - slit gratings, and 2 - hole, shared with fitting to enter the liquid.

The nozzle operates as follows: the liquid flows through the nozzle 4 (Fig. 1) in the nozzle chamber and out of it through the slit nozzle formed descending which, in particular, there can be used a semiconductor device integrated design comprising the circuit current limit and temperature, plugged in the vehicle and generates heat, which is transmitted by conduction to the liner, in one case, and the ribbon in the other, which prevents the freezing of liquid when using nozzles at low temperatures and creates the possibility of thawing frozen in the jet fluid at, for example, Parking the vehicle in the cold.

To test proposed designs were made two nozzles with a liner made of aluminum, in one case, and made of plastic, the other with aluminum tape. Corps in both cases were made of plastic by molding. As the fuel element was used chip KP-142 EH-5A with current limitation 1 and A temperature of 120oC. Nozzle steadily worked in the air stream at a temperature of -18oC and thawed 5 - 7 C.
