FR2624149A1 - DIVERGENT FLAT GUIDE FOR SANITARY FACILITY - Google Patents

Abstract

Jet guide intended more particularly to be fixed to the outlet of the tap of a sanitary installation, as an end piece, or to be integrated into the tap as a spout. Characterized in that it comprises: - A base part 1 which has an indentation in the shape of a vee with a rounded bottom furnished with small holes arranged substantially in an arc of a circle for the passage of water; - A substantially flat plate 7. The superposition of the plate 7 on the base part 1, forms a chamber 2 allowing the creation of a divergent flat water jet.

Description

-i - Jet guide for sanitary installations

  The invention relates to a jet guide intended more particularly

  the valves, which can be fitted to the outlet port of the latter as an end piece, or integrated into the tap as a spout. This jet guide has the distinction of producing a divergent flat jet. Existing flat jet guides produce a flat jet with parallel edges, the maximum width of which is spread over the width of the

jet guide.

  The width of this jet, which is often large, necessarily determines the width of the jet guide, and thus leads to the manufacture of large pieces which are

out of standard and therefore expensive.

  The object of the invention is to produce a flat jet whose width is increasing from a dimension jet guide.

  reduced, including a low cost.

  The amplitude of this flat stream can reach several times the

width of a jet guide.

  The thickness of this flat stream can be very low, giving

  and flat jet, an aesthetic similar to a film of water.

  The jet guide can be provided with a thread allowing it to be easily adapted to the mouth of a valve

usual standards.

  The accompanying drawing illustrates an example of a jet guide according to the invention. 1 '.

  jet and an example of the fixation of these.

one of the elements of the whole.

  The device, as illustrated in Figure 1, consists of: - A base part (1) which has a hollow recess with a flat bottom made by machining, or achieved by the addition of a thin plate to the contours similar to - 2- the face (5) of the piece (1). 2624149 This impression is substantially V shaped whose base

  The part (1) and the plate (7) have holes which

  face each other to assemble the device by means of screws (6).

  The superposition of the part (1) and the plate (7) form a chamber (2) delimited on one side by the flat face of the plate (7), and on the other by the bottom of the cavity. shape of vee. The device, as shown in Figure 2, is attached to

  the outlet of the tap via a connecting piece

  (11), which is a threaded sleeve which comes from one side, to screw on the outlet of the tap, and the other, to fix itself under the room

  (1) forming a cavity (12) feeding the holes (3).

  A variant of this arrangement, as shown in FIG. 3

  is to create a cavity (12) supplying the bores (3) direct-

  in the part (1) with a plug (13), this cavity

  being connected laterally to a water inlet (14).

  In both cases, this cavity (12) feeds a series of holes (3) arranged substantially in a semicircle. This semi-circular arrangement of holes of very small diameters, divide

water in small streams.

  This arrangement of semicircle holes is important because it determines the homogeneity of the water film at the exit of the device. Indeed, each jet of water taken individually, tends to create a non-homogeneous flow, the water being driven on the

  outer edges of the evacuation chamber.

  The multiplicity of holes (3), thus small jets of water, allows each of the jets in the evacuation chamber (2), to

  to rely on its neighbors, thus enabling a uniform distribution

form in this room (2).

  The holes for the water jets are preferably arranged

  this in an arc, so as to obtain a sufficient number of jets. Small jets of water strike against the plate (due

  The height of this chamber (2) determines the thickness of the flat stream. This flat jet is released from the room by its opening

and follows the profile of the plate (7).

  In the example shown in FIG. 1, the end

  bent over the plank orients the jet down.

  It is possible to act on the power and the flow of the flat jet, by acting on the feeding section and on the height

of the room (2).

  This method of assembly allows disassembly of the device, if

need is.

  This device can be realized, all or part, in

plastic or brass.
