Description

HYGIENIC SHOWER REGISTRATION

Field of the Invention

The present invention refers to a register, more specifically a register with manual opening and automatic and timed hydraulic closing, to control the flow of water to be supplied to the usual flexible feeding duct of a hygienic shower, the type normally used in toilets, to replace the well-known bidet.

The registration object of the present invention is also applicable to hydraulic installations, in which the connection of the registration body to the hydraulic installation network is provided with a bypass generally used to feed other consumption points in the bathroom environment, such as, by oxerr.plc, a box attached _to the toilet ^ positioned close to the hygienic shower installation point. Background of the Invention

Currently, hygienic showers are used _to __ replace the well-known bidet, due to the fact that they are more economical and require less physical space in the bathrooms of modern buildings, in which the space generally available does not allow an adequate installation for the well-known bidet.

The well-known hygienic showers comprise a diffuser head provided with a valve manually controlled by a trigger, the diffuser head being fed from a point of intake of the hydraulic supply network, through a manual operation register and a flexible duct that can present different constructions.

In many constructions, the diffuser head valve trigger is provided with a lock, so that the valve can be kept in an open condition without the user continuing to press the trigger.

In addition, in some installations, the manual override register is still provided with a bypass, usually in T, for connecting a pipe, rigid or flexible, to supply another consumption point in the bathroom, a point that is often defined by a flush box attached to the toilet and which is continuously fed, from the derivation of the register, regardless of the open or closed condition, of the latter.

In these known installations, the manual override register controls only the opening and / or closing of the diffuser head supply, through the flexible duct of the type generally used in manual shower showers, generally having a length of 1.20 to 1.50 meters and must be built to withstand dynamic pressure when the shower is running, particularly when the shower valve is closed, by releasing its trigger.

In this _ known ^ type of __inst_al.action, using the. record, manual opening and closing, the recommendation made to users, especially in high pressure installations, is that the record should always be closed ^ after using the shower and, even more preferably, before the trigger is released, that is, the closing the shower to avoid, in critical pressure situations, that possible water hammer in the hydraulic network could break the flexible duct and allow the leakage of pressurized water into the bathroom, while the valve remains open.

It happens that, invariably, users fail to close the register when the shower is finished, so the flexible duct remains continuously pressurized by the pressure of the available hydraulic network in the bathroom.

In the situations mentioned above, if there is a rupture or any structural failure of the flexible conduit, there will be a leak whose severity will be determined by the extent of the rupture of the flexible conduit and also by the pressure prevailing in the hydraulic supply network.

As is known, such accidents can cause considerable damage and loss to the user.

Summary of the invention

In view of the drawbacks and limitations of the state of the art, the present invention aims to provide a register for hygienic shower, which allows its opening by command of the user and that guarantees the interruption of the pressurized supply of the flexible duct and hygienic shower, after certain time of use of the latter, regardless of the user's performance on the record.

The register in question is of the type that comprises a body provided with: an inlet nozzle, to be connected to a hydraulic network; an outlet nozzle, to be connected to a flexible shower duct; a sealing seat, communicating the inlet and outlet nozzles; a obturator to be moved in the rear of the buck, - between a closed registration position, in which it is seated in the sealing seat, and an open registration position, in which it is removed from the sealing seat; and a_ driving means, to provide displacement of the shutter.

According to the invention, the displacement of the shutter to the open register position is performed by the user acting on the actuation means, the displacement of the shutter, from the open register position, to the closed register position, performed, automatic and timed mode, from the end of the user's action on the actuating medium and while the hydraulic pressure in the outlet nozzle is lower than the hydraulic pressure in the inlet nozzle of the register body.

With the new register mentioned above, to activate the hygienic shower, the user only needs to act on the actuating means, usually in the form of a rod, to cause the opening of the sealing seat, a condition that will be maintained for a certain time, even after being the activation medium released by the user. As the pressure in the outlet nozzle is lower than the pressure in the inlet nozzle and the actuation medium is released by the user, the plug will be slowly and progressively moved to the closed register position.

Description of the invention

As illustrated in the attached drawings, the R register in question is designed to be coupled to a terminal of a hydraulic supply network in a bathroom and to operate by means of manual opening and automatic hydraulic closing θ, allowing control of the flow of water. water to be supplied to a usual flexible CF duct for feeding a hygienic shower. The hygienic shower is not illustrated here or described in detail, as it is not part of the new construction applied to the R register for flow control.

The R register is defined by a body 10, generally cast in any metal alloy suitable for this type of device, internally cast and provided with an inlet nozzle 11, to be connected to a terminal of a hydraulic network (not shown) and of an outlet nozzle 12, to be connected to the flexible duct CF of the hygienic shower.

The body 10 may further be provided with an auxiliary nozzle 13, generally provided with an internal thread 13a and axially aligned with the outlet nozzle 12 and which is closed by a castle cover 14, provided with an external thread 14a. to be engaged with the internal thread 13a of the auxiliary nozzle 13.

The inlet nozzles 1.1 j and the outlet JL2-are selectively maintained in fluid communication with each other through a sealing seat S, internal to the body 10 of the R register and which will be described later._ _ - Õ body 10 further defines, internally , an AC supply chamber, arranged upstream of the sealing seat S and open to the inlet nozzle 11, and an outlet chamber CS, disposed downstream of the Sealing seat and open to the outlet nozzle 12.

In the illustrated configuration, the inlet nozzle 11 is arranged in a direction orthogonal to that. of the outlet nozzles 12 and auxiliary 13, the outlet nozzle 12 being generally provided with an external thread 12a for the coupling of an adapter sleeve 15, internally threaded and provided with a sealing ring 15a, for connection of an extreme adjacent flexible conduit CF, in a constructive arrangement well known in the art.

The R register in question may further comprise, inside the outlet chamber CS, a tubular jacket 20, made of metal alloy or plastic material, with a first end 21 seated against an internal annular stop 16 of the body 10, with the interposition of a ring gasket G, in elastomer, and a second end 22 fitted inside the castle cover 14 and closed by an annular insert 25 which is axially pressed, by the castle cover 14, against the second end 22 of the tubular jacket 20, length axially the first end 21 of this last 5 against the ring gasket G and against the internal ring stop 16 of the body 10.

The tubular jacket 20 has at least one radial opening 23 facing the interior of the CS outlet chamber, the first end 21 of the tubular jacket 20 10 being configured to have a trunk-conical cross section, facing the AC supply chamber and defining the S-seal seat of the R register.

The ring insert 25 has a tubular neck 25a, ... axially disposed and through which a drive means 15_30 is arranged, generally in the form of a stem -30a, mounted through the castle cover 14, to have an internal end 31, operatively associated with a shutter 40 to be selectively seated_ and away from the seat of. seal. S, as best described below, and an outer end 20 32 projecting out of the bonnet cover 14 and being coupled to a push button 60.

It is to be understood that the drive means 30 may comprise an electromagnetic impeller (not shown), operatively associated with the plug 40, to cause the latter 25 operational displacement. to the open register position.

obturator 40 takes the form of an elastomer ring mounted around an open end 51 of a tubular plunger 50, constructed of any suitable material, 30 axially disposed within the tubular jacket 20 and having an opposite end 52, closed by a wall end 53, generally in the form of an annular cover, provided with a central opening 54 that defines a control seat SC. The tubular plunger 50 is arranged through the 35 sealing seat S, with its open end 51, disposed inside the AC supply chamber, upstream of the sealing seat S.

The tubular plunger 50 carries, medially and externally, an annular sealing element 55, made of elastically deformable material and which is hermetically forced against an internal and radially adjacent wall of the body 10, the equalizing chamber CE being defined between the annular sealing element 55, the castle cover 14 (or annular insert 25 if provided), the tubular plunger 50 and said inner wall of the body 10. Said inner wall of the body 10 can be defined by the tubular jacket 20 or the inner wall the CS outlet chamber, in the event that the tubular jacket does not exist

20.

tubular plunger 50 is axially displaced inside. „Da_ CS exit chamber, between a closed R register position (figures 1 and _1A), _ na ... which - the -40- shutter is seated against the sealing seat S, and an open R register position ( figures 2 and 2A), in which the plug 40 is removed from the seat S, releasing the fluid communication, it will erase the AC supply chamber and the outlet chamber CS, through the sealing seat S, the inner tube sleeve 20 and the radial openings 23 of the latter.

In order to facilitate the passage of water through the sealing seat S, when opened by displacement of the plug 40, the tubular plunger 50 is laterally and axially provided with a plurality of external grooves 56 that have their .. wall, bottom radially indented in relation to to the contour of the sealing seat S.

The tubular plunger 50 defines, inside the tubular jacket 20, that is, inside the outlet chamber CS, an equalizing chamber CE, distant from the sealing seat S, limited by the annular insert 25 or by the castle cover 14 itself and that is maintained in restricted fluid communication with the outlet chamber CS by means of at least one groove 24, axial and internal to the tubular jacket 20 or through any other restricted passage produced in the body 10 of the R register and capable of restrictively communicating the CS output EC equalizer chambers.

The control seat SC defines a selective communication, between the equalizer chamber CE and the chamber of AC supply, through the interior of the tubular piston 50, whose open end 51 is arranged upstream of the seat of 5 seal S defined in the first end 21 of the tubular shirt 20.

The inner end 31 of the drive rod 30a carries, by means of a threaded engagement, an axial extension 33 dimensioned to project through the control seat 10 SC, to have an extended end head 33a carrying, peripherally, a control plug 35, generally in the form of an elastomer ring, to be seated and removed from the SC control seat, _respectively, _ ----- bdcrque “arrdo '~ é” Releasing the communication between the AC and equalizer chambers 15 CE ,. in- —function- * of the 'axial displacement printed to the actuation rod 30a by the user when pressing the actuation button 60, when opening the control seat, SC, „. and * automatícãmentê, by the action of an elastic means 70, when 20 the user stops pressing the activation button 60.

The elastic means 70 generally takes the form of a helical spring mounted around the outer end 32 of the actuation rod 30a, and compressed between the castle cover 14 and the actuation button 60, for force 25 axially the actuation rod 20 to a position of

- ~ control shutter 35 seated against the SC control seat.

The aforementioned construction allows the user to press the actuation button 60, displacing the actuation rod 30a and the control plug 35, causing the SC control seat to open and allowing the CE equalizing chamber to be pressurized with water from the the AC power chamber. Due to the difference in areas between the open end 51 of the tubular plunger 50 50 and the annular sealing element 55 of the latter, the pressurization of the equalizing chamber CE causes the tubular plunger 50 to be moved to the opening position of the sealing seat S of the R register, allowing the pressurization of the CF flexible duct and the shower diffuser head.

When the user releases the push button assembly

60 and the driving rod 30a, the elastic means 70, defined by a helical spring, forces the driving rod 30a to return to its resting position, in which the control plug 35 is seated against the control seat SC, blocking that last one. From that moment on, the EC equalizer chamber is gradually and slowly depressurized by the leakage of water to the CS outlet chamber, through the restricted fluid communication between the equalizer chamber _CE_ and the ._de _ s ~ áida "CS, defined one or more grooves 24, axial and
