Description

The invention relates to sanitary devices, namely, shower heads for a plumbing shower, and is intended for use mainly in domestic bathtubs for hydromassage procedures and to obtain an acupuncture effect on various parts of the human body.

A known shower head comprising a housing with a flow chamber located in it and permanently connected to the housing by a jet forming mesh with conical profile holes, the housing being equipped with a partition and the flow chamber equipped with a freely moving spherical body, the diameter of which is not less than the inner diameter of the outlet openings of the jet forming mesh [1 ].

The disadvantage of this device is the lack of the ability to replace the jet forming mesh, the need for which can be caused both by clogging of the nozzle openings and by matching the flow characteristics of the pressure system with the high-pressure head of the jets formed by the shower head, necessary for hydromassage procedures and the corresponding water acupuncture effect.

In addition, the use of conical profile holes in the jet-forming grids of shower heads does not provide the maximum kinetic energy of the jets [2], which, in turn, does not allow to achieve the maximum effect from hydromassage procedures in terms of achieving the corresponding water acupuncture effect due to the inability to obtain maximum hydrodynamic pressure of the jets on the treated surface.

Also known is a shower head containing a housing made of polymeric material with a side opening and a bottom with a jet forming mesh with cylindrical holes, threaded to the housing, as well as a water supply pipe and a reflective element fixed to the housing in the form of a tide or washer [3] .

The use of cylindrical holes in the jet-forming grid of the shower head of this device also does not allow to provide the maximum kinetic energy of the jets [2], which, in turn, does not allow to achieve the maximum effect of hydromassage procedures in terms of achieving the corresponding water acupuncture effect due to the inability to obtain maximum hydrodynamic pressure of the jets on the treated surface (µ = φ = 0.82).

In addition, the design of this device uses a jet-forming mesh with a constant number of nozzle openings, which can be a negative factor affecting the quality and effectiveness of hydromassage procedures, given the different flow characteristics of the mixer taps in specific conditions of different bathrooms and the different parameters of the hydrodynamic pressure of the jets the surface to be treated, required for massage of various parts of the human body.

Closest to the claimed technical essence and the achieved result, the known solution selected as a prototype is a shower head containing a nozzle for supplying water made of polymeric materials, a body and a bottom part connected to it by a thread, consisting of a nut and secured with it and two types of jet-forming grids installed inside the body, made with a ┼ or ┬-shaped profile, the vertical section of which, made solid, including spherical, is used for I place 19 or 61 nozzle openings of the conoidal profile and output diameters of the submillimeter section, and its horizontal section - to accommodate an o-ring of elastic material mounted on the corresponding diameter of the lower vertical part of the ┼ or ┬-shaped profile of the jet-forming mesh, while the inner surface of the housing is made with installation grooves for placement in the last protrusions, which are equipped with a horizontal section of the jet forming mesh, and a bevel for easy replacement after days, and the distance (in mm) between the centers of the outlet holes in the corresponding jet-forming grid (Δ) is determined from the condition:

A disadvantage of the known device selected as a prototype is its relatively limited functionality, which does not allow, in particular, to adapt the shower head to various flow characteristics of the pressure system used to provide the required water acupuncture effect, and, on the other hand, change the zone over a wide range jet processing while maintaining its predetermined intensity within the processing zone.

This is explained by the presence of only two types of jet-forming grids, on the one hand, and on the other, by restrictions on the size of the outlet diameter and the height of the nozzle holes in the jet-forming grid, as well as the number and type of the latter.

In addition, another disadvantage of this device is the relatively high consumption of material used for the manufacture of jet-forming nets.

A new technical result consists in expanding the functionality of the shower head, reducing the material consumption of its jet-forming nets, as well as increasing the efficiency and quality of hydromassage procedures implemented in a domestic bath, in the presence of an acupuncture therapeutic effect at various intensities and sizes of the blasting zones.

This is achieved by the fact that in a shower head containing a water supply pipe, a body and a bottom part connected to it by a thread, consisting of a through nut and fastened with it and installed inside the body, jet forming nets made with a ┼ or ┬-shaped profile, vertical a section of which is used to accommodate nozzle openings of the conoidal profile, and a horizontal portion thereof is used to accommodate an o-ring of elastic material mounted on an appropriate diameter of the lower vertical of the ┼ or ┬-shaped profile of the jet forming mesh, ACCORDING TO THE INVENTION, the upper part of the vertical section of each of the jet forming nets is performed as a set of separate jet forming nozzles of the corresponding output diameter, with the number of nozzle holes in the corresponding jet forming mesh (n ^Page ), selected from the ratio :

1≤n ^Page ≤61

), определяемым из соотношения:the size of the outlet diameter of the nozzle hole in the jet-forming grid ( $$d_{\mathrm{from}tR.}^{\mathrm{at}sx.}$$

) determined from the relation:

$$0.6\text{mm}\le d_{\mathrm{from}tR.}^{\mathrm{at}sx.}\le \mathrm{2,8}\text{mm}$$

and the height of the jet forming mesh itself (N _p. ), determined from the relation:

15d _p. ≤H _p. ≤25d _p.

In this case, the housing, the nut through passage and the jet-forming nets are made by injection molding of thermoplastic materials, which are used as polystyrene, ABC plastic, polypropylene, polycarbonate, etc.

And the distance (in mm) between the centers of the outlet holes in the corresponding jet-forming grid (Δ) is determined from the condition:

), определяют из соотношения:Moreover, the specific consumption of water (l / s) coming from the water source per one jet-forming grid necessary for hydromassage procedures at home ( $$q_{\mathrm{at}d.}^{\mathrm{FROM}tR.}$$

), determined from the ratio:

(при Р=0,2 МПа), $$\mathrm{0,03}\le q_{\mathrm{at}d.}^{\mathrm{FROM}tR.}\le 0.18$$

(at P = 0.2 MPa),

according to the actual value of which, for a particular bath, the number of outlet openings in the corresponding jet forming grid is selected.

The use of an expanded spectrum of replaceable jet-forming nets with different numbers, types and parameters of nozzle openings allows, on the one hand, to adapt the shower head to various quantitative characteristics of the pressure system used to provide the required water acupuncture effect, and, on the other hand, to change the blasting zone while maintaining its predetermined intensity inside the treatment zone.

In addition, the use of nozzle openings made in the form of a set of separate nozzles of the corresponding output diameter in the jet-forming grid can significantly reduce the consumption of material used for the manufacture of jet-forming grids and reduce the weight of the latter.

Thus, the claimed method meets the criteria of the invention of "novelty."

Signs that distinguish the claimed technical solution from the prototype are not identified in other technical solutions in the study of this and related areas of technology and, therefore, ensure that the claimed technical solution meets the criterion of "significant differences".

1 is obtained by molding a suitable thermoplastic material (such as polystyrene) under pressure into the mold shower head, as seen from the jet forming grid at n ^Pp. .

In Fig.2 presents a shower head in Fig.1, a side view with a vertical position of the shower head, section.

3 is obtained by molding a suitable thermoplastic material (such as polystyrene) under pressure into the mold shower head, as seen from the jet forming grid at n ^Pp. = 19.

Figure 4 presents the shower head in figure 3, a side view with a vertical position of the shower head, section.

5 is strueformiruyushaya mesh with mounting lugs, designed as a set of separate jet forming nozzles submillimeter (in this case) output diameter, n ^Pp. = 19, top view.

The shower head contains a housing 1 made of a polymeric (in this case) material, a threaded nut 2 connected to it by a thread, and a set of jet forming nets 3 with nozzle openings 4 of the conoidal profile and protrusions 5 (in this case) placed in the mounting grooves (in FIG. 1-4 not shown) of housing 1.

In this case, the installation of the selected jet-forming mesh 3 in the housing 1 is made through a sealing ring 6 of elastic material located under the protrusions 5 of the jet-forming mesh 3 at the corresponding diameter of its lower vertical part.

The proposed shower head operates as follows.

After determining (empirically) the value of the actual specific water flow with the temperature necessary for the procedure (usually not higher than 30-40 ° C) per one jet forming grid in a specific household bath, determine the number of outlet openings in the latter, in accordance with whereby the corresponding jet-forming mesh 3 is installed in the housing 1 through an o-ring 6 made of elastic material located under the protrusions 5 of the jet-forming mesh 3 at the corresponding diameter of its lower vertical noy part.

After that, using a threaded nut 2 with a thread, a reliable connection is made through the sealing ring 6 of the selected jet forming mesh 3 with the housing 1.

Closing the shutter-screen (to prevent water splashes outside the volume of the household bathtub) and adjusting the flow rate and the required temperature of the water used during hydromassage using the corresponding valves of the mixer tap (Fig. 1), the device is prepared for hydromassage procedures.

In this case, unlike the prototype, which allows the formation of water jets only of a submillimeter cross section of maximum kinetic energy, the claimed device, while maintaining the latter, allows you to generate a single water jet with a diameter of 2.8 mm (n ^p. = 1), or a packet of water jets with a diameter of 1.2 mm (n ^p. = 7) corresponding to jet-forming nets with reduced material consumption used for the manufacture of jet-forming nets and reduced weight of the latter.

Thus, the proposed shower head for carrying out hydromassage procedures in a domestic bath, in comparison with the known one selected as a prototype, has advanced functionality that allows hydromassage procedures of the human body in a domestic bath with a wider and more variable area and intensity of blasting, in the presence of an aqueous acupuncture effect, and improved weight and size characteristics.

The implementation of the proposed device does not meet fundamental difficulties.

Thus, jet-forming nets can be made according to RF patent No. 2046685 with a nozzle hole structure formed in accordance with RF patent No. 2296672 using appropriate thermoplastic material, molds and equipment, for example, an automatic molding machine of the type ARBURG - A 270-21-500.

And as a thermoplastic material for hydromassage panels, you can use polystyrene, ABC - plastic, polycarbonate, polypropylene or acrylic.

Comparison of the technical features and functionalities claimed shower head for whirlpool treatments in the tub with a prototype consumer and domestic and foreign similar purpose devices, as well as experimental studies, for n ^p. = 1, 7, 17, 19, 37 and 61 indicate the guaranteed achievement of a new technical result in bathrooms with various quantitative parameters of pressure systems and requirements for the intensity and type of hydromassage procedures being implemented.
