Description

ELECTRIC SHOWER BACKGROUND OF THE INVENTION 1. Field of the Invention The present patent of invention refers to Electrical Shower, or more particularly, to different technical and functional improvements that were achieved by means of mechanical, electrical and structural arrangements, developed especially with a view to the characterization of a compact electric shower.

Obviously, it was possible to achieve this compact form by virtue of a new construction applied to the body of the shower which, in this case, was substantially reduced in height, which required that a new arrangement of the electrical and mechanical components be carried out. , including a totally new temperature selection mechanism, since, in opposition to conventional models, it does not appear in the form of a lever acting radially from the outside towards the inside of the apparatus, but acts in the form of an envelope or upper cover that, on the underside, it presents a kind of cube to guide it in order to allow it to have a very short turn in both the clockwise and counterclockwise directions and, in this condition, an internal selector plate also rotates in the same way, performing in a different way the temperature selection.

The second objective of the invention is to provide different mobile electrical contacts, that is to say, in a first constructive version the contacts are phacoidal and are fixed in plates with set of springs, one of them integrates or forms a constructive part of a diaphragm that is it moves with the hydraulic pressure and, in this way, the opening or closing of said contacts takes place, characterizing an effective way of driving, since that this coupling depends solely and exclusively on the water pressure of the shower In a second construction version is also provided a completely unprecedented system for opening and closing the contacts, in which two of these contacts are fixed while the other two are of the laminar and rectangular type, coupled by an end to a coplanar support which, in turn, operates as a scale that goes up and down; the end is fixed articulately, and in the middle part a vertical bolt of the diaphragm actuation system acts and, in this way, said support oscillates up and down, raising and lowering the movable contacts, approaching them or moving them away from the fixed contacts and , that this condition, the electrical resistance of the shower is connected and disconnected.

In a third construction version, another completely unprecedented drive system is provided for the opening and closing of the contacts, especially since the movable contacts are mounted on a swinging piece or support in the manner of a rocker, which, at one end, is it can be activated by the vertical axis of the diaphragm, while, at the opposite extremity, it seats two electrical contacts, moving them upwards or downwards in such a way that they can or can not contact other fixed contacts, establishing or interrupting the passage of the electric current towards the resistance of the shower. This mechanism, in addition to completely different from those currently known, also allows proper operation of the contacts, including making them self-cleaning and, in addition, the rocker configuration attributes to the support a lever effect that greatly enhances the operation of the device, since In this way, the diaphragm's action becomes much smoother and avoids effort excessive of the moving components, considerably increasing the useful life of the device.

Therefore, one of the objects of the invention is precisely the combination of various mechanical, electrical and structural arrangements, not only to characterize a shower substantially more compact than those that exist today, but also to offer an apparatus that can work with greater precision and with a really reduced manufacturing cost.

According to these illustrations and their details, especially in figures 1 to 6, the present invention patent electric shower is characterized by having a shell-shaped body, defined by four parts injected in plastic material; the first one is constituted as the body proper (1) arched spherically upwards or in the form of a shell face down, completely open at the bottom, with a cylindrical neck (2) for coupling a separating disc (3) and, below it is the screen or spout (3). Between the latter and the disc, the first distribution chamber (5) is formed with a lateral tubular outlet (6) that carries the manual shower (no is illustrated). Inside the body (1) a wet chamber or heating chamber (7) is formed which, in addition to including a subsequent connection for water inlet (8), is also limited at the top by an intermediate and horizontal wall ( 9), above which the dry chamber or arming chamber (10) of the electrical part or mobile contact mechanism (11) is formed which, by the upper part, is closed by means of temperature selection device (12); in the lower part it is activated mechanically by means of a drive mechanism that operates with the pressure of the water that enters through the connection (8). This mechanism is configured in conjunction with the separating disk (3) that, for this, it has a raised part in the center, with the shape of a siphon tube (13), vertical. The upper extremity ends precisely below the lower surface of the diaphragm (15), and its internal configuration resembles the shape of a truncated cone (cone-shaped) sealing housing (14) and constitutes an entry point or point of water passage of the camera. heating (7) to the distribution chamber (5). However, this step is automatically controlled by the assembly comprised by the diaphragm (15), which is characterized by a cylindrical perimeter (16) fixed inside an equally cylindrical seat (17) that is located in the separation wall ( 9). The diaphragm in the central part has a rigid plate (18) superimposed in such a way that between it and the section (16) the diaphragm can have a cushioned loop (set of springs) (19). Also, said rigid plate (18) presents a first central detail in the form of obturator or truncated plug (20) projected vertically downwards and oriented so that it is fitted inside the sealing housing (14) of the siphon tube ( 13) wherein said shutter favors vertical movement upwards or downwards and constitutes the main opening and closing element of the water passage from the heating chamber (7) to the distribution chamber (5); this movement is guided since said shutter (20) also extends upwards of the plate rigid (18), thus configuring a vertical guide rod (21) in different diameters, housed and slidable inside a suspendable tubular sector (22) which, in turn, has the upper end formed as a real circular cover or cover (23), face down, whose lower edge or end diameter is structurally integrated with the diameter corresponding to the opening or cylindrical section (17) of the partition wall (9); thus, the interior of said cover defines the dry assembly compartment of the electrical assembly (11).

The electrical assembly (11) is formed, at first, of bolts or contacts in the form of rods (24) that pass vertically through the rigid plate (18) and the diaphragm (15) and are exposed below the latter. There they are configured as coupling means for the electrical resistance (25) which, in turn, is assembled as if it were a collar around a circular support of the cage type (26) with cylindrical receptacles (27). These receptacles internally house the terminals of the resistor (25) in such a way that, at this point, the electrical connection can be made with the bolts (24), whose upper ends, on the rigid plate (18) have the heads in shape lenticular and constitute the mobile contacts (28) of the resistor (25). These contacts are below and in alignment with other similar movable contacts (29), but armed in terminals fixed in a plate with set of springs (30) in the form of a disk that, on the upper face, has resources for the already referred terminals are connected to the cables (F). In addition, this plate is guided, by its external diameter, inside the vertical cylindrical wall of the lid (23), while the central hole passes to the tubular suspense sector (22) which, in turn, has two coil springs, one of them external (31) and the other internal (32). The first acts directly on the plate (30), the second involves the rod (21) of the diaphragm (15) keeping it pressed down. The upper ends of said rod (21) are like nails (33) and go beyond an internal flange (34) that is in the highest part of the tubular sector (22), limiting in that place the downward movement of the diaphragm (15) when the opening of the contacts (28 and 29) occurs, it is clear that this will occur when there is no hydraulic pressure inside the heating chamber (7) and, under these conditions, the electrical resistance (25) is disconnected, but, in the reverse situation, the electrical contacts (28 and 29) close and connect the resistor (25), but still this will depend on a switch on / off switch and on temperature (35).

The selector key (35) is presented in the form of a true circular plate, whose front fork-shaped edge (36) is crimped on a vertical bolt (37) which, in turn, has the upper end formed by an envelope upper (38), which extends accompanying the spherical format of the body (1), that is, it is presented in the form of a rectangular-shaped plate that extends from the back to the front of the body (1), ending in the form of front button (39), and cooperates so that this envelope can act as a selector key; for this, the envelope has on its lower face with projections (40) oriented vertically downwards and has the trailing edge in the shape of a fingernail (41), in such a way that these sectors can penetrate in a blocked manner in a neck also ordinarily circular (42) which is located in the upper part of the lid (23) wherein said projection (40) can be rotated together with the casing (38) and at a sufficient angle so that the rod (37) can also move the selector plate (35) allowing the regulation (winter - summer - disconnects) of the shower.

As illustrated in figure 7, in the projection (41) under the wrapping (38) the pressing device is fitted to the cable (43) which, in turn, includes holes to pass the cables (F), including the ground cable (Ft) which is of the coated type and crosses vertically the water entry point of the connection (8) where a small section is located uncoated (Fd) and again coated, extending below the separator (3), ending inside the siphon tube (13) where its finish is also uncoated (Fd), which configures the capture of the leakage current.

As illustrated in the detail of Figure 8, the spreader (4) is coupled to the body (1) by means of a thread (44); under this thread, the internal side of the separator has a channel (45) and a sealing lip (46), both verticals that relate to another channel (47) and another sealing lip (48) on the perimeter and in the lower face of the separating disk (3) which, finally, fits in the same way, that is, through its vertical lip (49) and a channel (50) located in the internal diameter of the sector (2) of the body (1) The operation of the assembly described above is extremely simple, as shown in figure 5. It can be seen that the water enters through the connection (8) and invades the heating chamber (7) which, in turn, always remains flooded and , therefore, the electrical resistance (25) is submerged, thus preventing it from running without water. The water inlet in the chamber (7) causes an increase in pressure sufficient for the diaphragm (15) to be actuated. This drive consists of moving upwards and, with this, moving the plate (18) producing the closure of the contacts (28 and 29) and, with these conditions, the electric current passes from the wiring (F) to the resistance (25) , making it work. At the same time the upward movement of the plug or plug occurs (20) releasing the water that was heated in the chamber (7) in such a way that it can flow through the siphon (13) by flooding the chamber (5) from where it exits through the spreader (4). In this condition there is also the capture of leakage current through the system formed by the cable (Ff). While there is pressure in the chamber (7) the system keeps running, otherwise, the diaphragm (15) returns to its original position, closing step (14) and, at the same time, disconnects the contacts (28 and 29) and , therefore, the electrical resistance (25) is also switched off.

The selector plate (35) allows the switching between the various contacts (28 and 29) and also the complete isolation between them, that is, according to the position of this plate the contacts do not touch even when the water enters. In this condition, the apparatus is disconnected, but in other positions, as can be seen in Figure 9, said plate can be moved to allow the apparatus to operate in two different conditions, "winter" or "summer". This commutation is carried out by means of the button (39) which, when moved to the right or to the left, causes the casing (38) and the pin (37) to move; the latter rotates the selector plate (35) and the apparatus can then be switched on / off or set to operate in one of the "summer" or "winter" possibilities.

The first spring (31) constitutes the means by which the plate (30) of the contacts (29) can be kept pressed down and against the contacts (28).

The spring (32) applies a slight pressure against the rigid plate (18) of the diaphragm (15). When the pressure in the interior of the heating chamber (7) ceases, the pressure of this spring (32) favors the return of the assembly.

In a second constructive variation, as illustrated in figures 10 and 11, a different drive mechanism (51) is provided, although it is also formed by a vertical rod (21), but in this case, the rod widened in the form of disk (52), located under the wall (9) where it finds assembly details (53 and 54). The first detail is a lower recoil for the same disc, and the second is a vertical guide collar that houses the upper part of this rod (21) and a spring (55) that normally keeps it pressed down and also, in this part of the rod (21) the upper extremity is sufficiently exposed for coupling to occur with the contact mechanism (11). At the bottom, this rod (21) forms a shutter or truncated plug (20) projected vertically downwards and oriented so that it fits inside the sealing housing (14) of the siphon tube (13), there the shutter moves up and down vertically by means of a circular diaphragm (56) which, by the central region or internal diameter, is coupled below the disc (52) of the rod (21), while its outer diameter it projects vertically downwards according to a cylindrical section (57), fitted inside an equally cylindrical projection (58) that is located below the wall (9) where the detail is assembled (53) presents sufficient dimension so that the diaphragm (56) and the rod (21) can be moved upwards by the same pressure of the water that enters through the connection (8) and, thus, the activation of the electric part (11) occurs, connecting and disconnecting the electrical resistance (25).

The electrical assembly (11) is illustrated with details in figures 11 to 13. There it can be seen that this assembly is constituted by a dielectric support (59) in the form of a "T" lying down. The terminal of its central branch is coupled (60) with the end of its branch central is coupled (60) with the upper end of the drive rod (21).

Already in the transverse branch, the terminals are provided with drawer-type assemblies (61) for the rear ends of movable laminar contacts (62) that although on the one hand are interconnected with the power supply cables (F), at the ends free are located below the fixed contacts in inverted "L" (63). The upper extremities are horizontal and are directed in a coplanar fashion against each other; and the lower extremity projects vertically downwards through the wall (9) to form two coupling terminals (64) for the resistance (25), whose third terminal is represented by a third flexible laminar contact (65) which, by the extremity later, it crosses the wall (9) in the same way; and the anterior limb is located under an extension or spigot (66) of one of the "L" contacts (63). In this way, the pin and the movable contacts (62) may or may not be in selective contact with the fixed contacts (63) by means of a multi-position key (67), made of dielectric material, whose tubular central part (68) it is rotatably nailed to a pivot (69) that extends vertically from said wall (9) in which the tubular part has a branch radially directed forward (70) and coupled with the temperature selector (38). On the opposite side of the tubular sector (68) there are three more radial projections, one lower singular (71) and two other equal ones (72). The first is oriented to pass under the pin or third contact (65), pushing it against the detail (66) of one of the fixed contacts (63) thus establishing the electrical connection of this contact with the corresponding terminal of the electrical resistance (25), and the other two terminals work as insulating pins and may or may not be located between the terminals of the fixed (63) and mobile (62) contacts and, in this way, when the shower is connected, if these pins are between the corresponding parts of the contacts, fatally not will produce the electrical connection, however, the opposite situation will fatally produce the electric resistance drive (25).

The dielectric support (59) is guided and stably guided in its downward and upward movements by means of a rear groove (73) and a bolt (74) that extends vertically in the wall (9).

As illustrated in figures 14 and 15, in a constructive variation, this same modified electrical assembly (11) and all its actuating details, including the key (67), can be mounted inversely, in a 180 ° displacement relative to the point central defined by point (60).

From the above description, it can be noted that the operation of the shower in question, according to the second constructive variation, is indeed very simple, as can be seen in figure 10. The entrance of the water, in this case, occurs through the connection (8) and invades the heating chamber (7) that is always flooded and, consequently, the electrical resistance (25) is also kept submerged, which prevents it from running without water. The water inlet in the chamber (7) causes an increase in pressure sufficient for the diaphragm (56) to act. This actuation means that it moves upwards and with this moves a bolt (21) causing the closure of the contacts (62 and 63) to occur and, in this condition, the electric current passes from the wiring (f) to the resistance ( 25), putting it into operation. At the same time, the upward displacement of the plug or plug (20) is also produced, releasing the hot water in the chamber (7) in such a way that the water can flow through the siphon (13) by flooding the chamber (5). ) from where it comes out through the screen (4). In this condition there is also the capture of leakage current through the system formed by the cable (Ft). While there is pressure in the chamber (7), the system remains in operation, otherwise, the diaphragm (56) returns to its original position, closing step (13) and, at the same time, disconnects the contacts (62 and 63).

The selector (38) by means of its button (39) and the key (67) allows the switching between the various contacts (62-63-66-65), as well as the total isolation between them, that is to say, according to the position, these contacts do not touch even when the water enters. In this condition the device is disconnected, but in other positions the selector can be moved to allow the device to operate in two different conditions: "winter" or "summer". This commutation is carried out by means of the button (39) which when moved to the right or to the left moves the casing (38) and the key (67) and, with this, the apparatus can be switched on / off or operate in the temperatures "summer" or "winter".

In figure 11 it is also possible to see that the pair of laminar contacts (62) allows an adequate efficiency when it is in operation, not only because it is fixed in a structure with set of springs, but also because of its flexibility, in this way they become also in self-cleaning.

In a third construction variation, illustrated in figures from 16 to 22, a different drive mechanism for the contacts is provided. Figure 18 shows more details of this mechanism formed by a mobile dielectric support in the manner of a rocker (75) which, seen from above, resembles a lying "Y", and whose extremities have different planes: the plane more high is the unique branch and back (76), while the front branch, bifurcated (77), is in a lower position and, in addition, this support or rocker (75) presents its pivoting median part (78), cooperating so that the support can oscillate by raising and by lowering its extremities and, for this, only the rear one (76) is configured so that the drive mechanism (51) activates it; for this purpose, it has a rod (21) provided with an upper extension (78) ending in self-locking head (79) that is coupled in a suitable hole that exists in the corresponding part of the said branch (76) of the oscillating support (75); and at this point, a spring (80) surrounds the extension (78), and at the same time, the upper and lower end of said spring (80) rests, respectively, between the branch (76) and a step / washer ( 81) located at the bottom of the extension (78). An appropriate set is thus configured to lift the corresponding part (76) of the rocker support (75), further this movement is driven by a bolt (82) that passes vertically and freely through a distal hole that exists in the branch (76). ). The bolt at its lower end is nailed to a vertical projection (83) that emerges from the wall (9), and to the upper extremity is provided with a limiting head (84) of the movement of the branch (76), in such a way that it makes raise and lower correctly the bifurcated extremity (77) of the support (75) where the movable contacts (85) are fixed, which in their upper part are interconnected with the power supply cables (F), and in their lower part they are aligned over the fixed contacts in inverted "L" (63), whose upper extremities are horizontal and. directed coplanarly against each other, while the lower extremity projects vertically downwards through the wall (9) to form (figure 16) two terminals (64) coupling for the resistance (25). The third terminal is represented by a third flexible laminar contact (65) which, at the rear end, crosses the wall (9) in the same way, while at the front end it is placed under an extension or pin (66) of one of the "L" contacts, so that this pin and the movable contacts (85) may or may not be in selective contact with the fixed contacts (63) by means of a multi-position key (67). ), whose configuration is the same as that of the previous constructive version, including as regards its operation.

As illustrated in Figures 21 and 22, in another constructive variation, the same electric drive assembly defined by the rocker (75) and all its drive details, including the key (67) can be mounted inversely, according to a displacement 180 ° relative to the central point (78) of the set.

In this last constructive variation, the operation of the shower is practically the same compared to the previous version, as illustrated in figures 16, 17 and 18. There it can be seen that the entrance of the water occurs through the connection ( 8) and invades the heating chamber (7) which, in turn, is normally flooded and consequently, the electrical resistance (25) remains submerged preventing it from running without water. The water inlet in the chamber (7) causes an increase in pressure sufficient for the diaphragm (56) to be actuated. This drive consists of its upward movement so as to move the bolt (21) causing the rocker (75) to oscillate in the direction of closing the contacts (85-63) and, in this condition, the electric current passes from the wiring ( F) to the resistor (25) putting it into operation. At the same time, the upward displacement of the plug or plug (20) also occurs, releasing the hot water in the chamber (7). It thus flows through the siphon (13) flooding the chamber (5) and exits through the screen (4). In this condition there is also the capture of leakage current through the system formed by the cable (Ft). While there is pressure in the chamber (7) the system keeps working, otherwise the diaphragm (56) returns to its original position closing step (13) and., at the same time, disconnects the contacts (85-63).

The selector (12), by means of the button (39) and the key (67) allows the switching between the various contacts (85-63-62-65), and also allows the complete isolation between them, that is, according to the position of the key these contacts do not touch even when the water enters. In this condition, the device is disconnected, but in other positions, the selector can be moved to allow the device to operate in two different conditions: "summer" or "winter". This commutation is carried out by means of the button (39) which, when moved to the right or to the left, causes the casing (38) and the key (67) to move; the device can then be connected / disconnected or placed to operate in one of the possibilities "summer" or "winter".

In figure 18, it can also be noted that the pair of movable contacts (85) allows an adequate efficiency when it is operating not only by being fixed on a rocker but also by the set of springs so that the contacts become self-cleaning

At the bottom, this rod forms a shutter or truncated plug vertically projected downward and oriented so that it is housed inside the sealing housing of the siphon tube where the shutter can be moved both vertically and vertically by means of a circular diaphragm that, by the central region or internal diameter, is coupled below the rod disc, while its external diameter runs vertically downwards according to a cylindrical section, fitted inside an equally cylindrical projection that is underneath the wall where the assembly detail has sufficient dimensions so that the diaphragm and the rod can be displaced upwards by the same pressure of the water that enters through the connection and, thus, the electric part is activated, connecting and disconnecting the electrical resistance. "Electric Shower", in accordance with claim 7, is characterized in that the electrical assembly of the second constructive version is constituted by a dielectric support in the form of a "T" lying down. The terminal of its central branch is coupled with the upper end of the driving rod. Already in the transverse branch, the terminals are provided with drawer-type assemblies for the rear ends of movable laminar contacts that although on the one hand are interconnected with the power supply cables, by the free ends they are below the fixed contacts on the side. "L" inverted. The upper extremities are horizontal and directed in a manner coplanar against each other, and the lower extremity projects vertically downwards, crossing the wall to form two coupling terminals for resistance, whose third terminal is represented by a third flexible laminar contact that, by the posterior extremity, it crosses the wall in the same way, while the anterior limb is under an extension or spike of one of the "L" contacts. In this way, the pin and the movable contacts may or may not be put in selective contact with the fixed contacts by means of a multi-position key, of dielectric material, whose central tubular part rotates nailed to a pivot that emerges vertically from the aforementioned one. wall in which the tubular piece has a branch radially directed forward and coupled with the temperature selector. On the opposite side of the tubular sector are three more radial projections, one lower singular and two others equal to each other. The first is oriented to pass under the pin or third contact, pushing it against the detail of one of the fixed contacts thus establishing the electrical connection of this contact with the corresponding terminal of the electrical resistance, and the other two terminals work as spikes insulators and may or may not be placed between the terminals of the fixed and mobile contacts and, thus, when the shower is connected, if these pins are between the corresponding parts of the contacts, the electrical connection will not necessarily occur, however , the opposite situation will fatally produce the electric resistance drive. "Electric Shower", in accordance with claim 7, is characterized in that the dielectric support is guided and stably guided in its downward and upward movements by means of a rear groove and a bolt that extends vertically from the wall. "Electrical Shower", in accordance with claim 3, is characterized in that in a constructive variation, this same modified electrical assembly and all its actuating details, including the key can be mounted inversely, in a 180 ° displacement in relation to the central point defined by the point. "Electrical Shower", in accordance with claim 3, is characterized in that, in a third variation, a different drive mechanism is provided for the part of the contacts and for this a mobile dielectric support is included as a rocker that , seen from above, it looks like a "Y" lying down, and its extremities are in different planes: the highest plane is the single and posterior branch, while the anterior branch, bifurcated, is in a lower position and also, this support or rocker presents in its pivoting, cooperative median part so that the support can oscillate by raising and lowering its extremities and, therefore, only the rear one is configured so that the actuating mechanism activates it; for both it has a rod provided with an upper prolongation that ends in self-locking head that is coupled in a suitable hole that exists in the corresponding part of the branch of the oscillating support; and, at this point, a spring surrounds the extension, and at the same time, the upper and lower end of this spring rests, respectively, between the branch and a step / washer existing in the lower part of the extension. In this way, a suitable set is configured to lift the corresponding part of the rocker support, furthermore, this movement is driven by a bolt that passes vertically and freely through a distal hole that exists in the branch. The pin at its lower extremity is nailed to a vertical projection that leaves the wall, and the upper extremity is provided with a limiting head for the movement of the branch, in such a way that it makes the bifurcated extremity of the support to rise and fall correctly. the movable contacts are fixed, which are interconnected at the top with the power supply cables, and in their lower part are aligned on the fixed "L" inverted contacts, whose upper ends are horizontal and directed in a coplanar manner the one against the other, while the lower extremity projects vertically downwards, crossing the wall to form two coupling terminals for the resistance. The third terminal is represented by a third flexible laminar contact that, at the rear end, crosses the wall in the same way, while the front end is placed under an extension or spike of one of the "L" contacts so that this pin and the movable contacts may or may not be put in selective contact with the fixed contacts by means of a multi-position key, whose configuration is the same as that of the previous constructive version, including as regards its operation. "Electric shower", in accordance with claim 11, is characterized in that, in another constructive variation, the same electric drive assembly defined by the rocker and all its actuating details, including the key can be mounted inversely, according to a 180 ° offset relative to the center point of the assembly. SUMMARY Patent of invention electric shower with shell-shaped body, defined by four pieces injected in plastic material, the first being defined as the body itself, arched spherically upwards or shell-shaped upside down, completely open at the bottom, where an assembly cylindrical neck is defined for a separating disk and, below it, the screen or spacer. Between the latter and the disc, a first distribution chamber is formed with a lateral tubular outlet that reaches the manual shower, while inside the body the wet chamber or heating chamber is formed which, in addition to including a later inlet connection water is also limited in its upper part by an intermediate and horizontal wall on which the dry chamber or assembly chamber of the electrical components is formed. This camera closes it at the top the temperature selection device; thus, the water inlet is produced through the connection and invades the heating chamber, which, in turn, is always flooded and, consequently, the electrical resistance is always submerged. The water inlet in the chamber causes an increase in pressure sufficient for the diaphragm to be activated and thereby moves the square causing the contacts to close and, in this condition, the electric current passes from the wiring to the resistance, putting it into operation.
