Definitions
- the present Patent of Invention relates to an "ELECTRIC
- SHOWER or more particularly to different technical and functional improvements, obtained by means of mechanical, electrical and structural arrangements specially developed aiming the characterization of a compact electric shower.
- the compact fo ⁇ n could be obtained due to a new construction applied to the shower body that, in this case, had its height substantially reduced, thus requiring a new arrangement of the electrical and mechanical components, including the adoption of a completely new temperature selection mechanism, since, in contrast with the conventional models, it is not shown in the form of a lever which acts radially from outside to inside the device, but in the fo ⁇ n of a top cover that, by means of the bottom face, has a kind of cube for guiding it in a direction so as to allow its very short rotation both clockwise and counterclockwise and, in this condition, an inner selector plate is also rotated in the same way, thus providing a different temperature selection mode.
- the second object of the invention is to provide different movable electrical contacts, that is, in a first constructive version, the contacts are knife-shaped and fixed in springiness plates, one of them being integral or being a constructive part of a diaphragm which moves with the hydraulic pressure and due to this movement there occurs the opening or closing of said contacts, characterizing an effective actuation means, since it depends solely and exclusively on the pressure of the shower feeding water.
- a completely novel actuation system for opening and closing the contacts, wherein two of said contacts are fixed, while the other two are of the laminar and rectangular type, being integrated by an end to a coplanar support that in turn operates as a seesaw, having an articulately fixed end, while on its inte ⁇ nediate portion there acts a vertical pin of the diaphragm actuation system and thus said support swings as if it were a seesaw, lifting and lowering the movable contacts, towards or outwards the fixed contacts and, in this condition, the shower electrical resistor is tu ⁇ ied on and off.
- a third constructive version it is provided another completely novel actuation system for opening and closing the contacts, mainly characterized in that the movable contacts are mounted in a swinging piece or support as a rocker that, through one end, can be actuated by the diaphragm vertical shaft, while in the opposite end, it houses two electrical contacts moving them up and down so that they can contact or not the other fixed contacts, allowing or interrupting the electrical current to pass towards the shower resistor.
- This mechanism besides being different from those cu ⁇ ently known, also allows an appropriate operation of the contacts, even rendering them self-cleaning, and also the rocker configuration imparts the support a lever effect which cooperates with the device operation and thus the diaphragm actuation becomes smoother and avoids the excessive stress of the movable components, considerably increasing the device useful life.
- one of the objects of the invention is exactly a combination of several mechanical, electrical and structural arrangements, not onl> for characterizing a substantially more compact shower than the existing oi. ⁇ s, but also to provide a device that can operate with higher accuracy and with a really reduced manufacturing price.

- ELECTRIC SHOWER is characterized in that it comprises a shell-shaped body, defined by four injected pieces made of plastic, the first one being defined as the body itself (1 ) spherically cambered upwards or in a shell shape upside down, completely open on the bottom portion, wherein it is defined a cylindrical engagement groove (2) for a separator disk (3), being positioned under it the strainer or spreader (4) thus forming, between the latter one and the disk, a first distribution chamber (5) with a side tubular outlet (6) for the manual tiny shower (not shown), while inside the body ( I ) there is fo ⁇ ned a wet chamber or heating chamber (7) that, besides including a water inlet rear connection (8), is also limited in the top portion by an inte ⁇ nediate and horizontal wall (9), over which it is fo ⁇ ned the dry chamber or assembling chamber (10) of the electrical part or movable contacts mechanism ( 1 1 ) that
- the electrical assembly (1 1 ) is initially fo ⁇ ned by pins or contacts in the shape of pins (24) which vertically cross the rigid plate ( 18) and the diaphragm ( 15), exposing under this latter, wherein they configure coupling means for the electrical resistor (25) that, in turn, is mounted such as to be glued around a cage-type circular support (26) having cylindrical receptacles (27), these latter housing internally the terminals of said resistor (25) so that at this point the electrical connection with the pins (24) can be carried out, whose top ends over the rigid plate ( 18) are shaped as lens heads and constitute the movable contacts (28) of resistor (25) which are under and aligned with other similar movable contacts (29), however, they are mounted in fixed terminals in a springiness plate (30) in the shape of a disk that, through the top face, provides means for said te ⁇ ninals to be connected to the wiring (F), said plate (30) being still guided by its outer diameter mside the cylindrical vertical wall of cap (23
- the selector switch (35) is shaped as a true circular plate, the front forked edge (36) of which is set in a vertical pin (37) that, in tu ⁇ i, has its top end integrated with a top cover (38) which extends following the top spherical shape of body (1 ), that is, it is shaped as an ordinarily rectangular plate that extends from the rear portion to the front portion of body ( 1 ), te ⁇ ninatuig in the shape of a front button (39) cooperating such that said cover can operate as a selector switch and for this purpose said cover has its bottom face provided with protrusions (40) vertically oriented downwards and having its rear edge shaped as a narrow opening (41 ), such that said sectors may penetrate in locked fashion in an also ordinarily circular collar (42) existing in the cap (23) top portion, said protrusion (40) being able to rotate together with said cover (38) and according to an appropriate angle for the rod (37) to move in the same way as the selector plate (35) does, thus allowing the
- the wire press (43) that, in turn, includes orifices for the wiring (F) to pass, including the ground wire (Ft) that in tu ⁇ i is of the wrapped type and also vertically crosses the water inlet point of connection (8), wherein it has au unwrapped portion (Fd) and again wrapped, it continues and extends under the separator (3), terminating inside the siphon tube (13), wherein its terminal is equally unwrapped (Fd), thus configuring the leakage current capture system.
- the wire press (43) that, in turn, includes orifices for the wiring (F) to pass, including the ground wire (Ft) that in tu ⁇ i is of the wrapped type and also vertically crosses the water inlet point of connection (8), wherein it has au unwrapped portion (Fd) and again wrapped, it continues and extends under the separator (3), terminating inside the siphon tube (13), wherein its terminal is equally unwrapped (Fd), thus configuring the leakage current capture system.
- the spreader (4) is coupled into the body ( 1 ) by means of thread (44), under which the inner side of said separator has a channel (45) and a sealing lip (46), both vertical, which engage to another channel (47) and another sealing lip (48) provided in the perimeter and bottom face of the separator disk (3) that finally engages in the same way, that is to say, by means of its vertical lip (49) and a chute (50) existing in the inner diameter of sector (2) of body ( 1 ).
- the selector plate (35) allows switching among the several contacts (28-29), as well as the total insulation among them, that is to say, depending on the position of said plate, said contacts do not get into contact to each other even when the water intake occurs. In this condition, the device is turned off, however, in other positions, such as illustrated in figure 9, said plate can be moved to allow the device operation in two distinct conditions, winter or summer.
- This switching is carried out by means of button (39) that, when displaced to the right or to the left, causes the cover (38) and the pin (37) to move, this latter causing the selector plate (35) to rotate and thus the device may be turned on/off or put into operation in the "summer or winter" temperatures.
- the first spring (31) composes a means so that plate (30) of contacts (29) can be normally kept pressed downwards and against the contacts (28).
- Spring (32) exerts a slight pressure against the rigid plate (18) of diaphragm (15), and while it ceases the pressure inside the heating chamber (7), the assembly return is favored by the pressure of said spring (32).
- actuation mechanism (51 ) although it is also composed of a vertical rod (21 ), in this case, however, said rod is intermediately enlarged in the shape of a disk (52), positioned under the wall (9), wherein it finds engagement details (53) and (54), the first detail being a lower backward movement towards the disk itself, while the second one is a vertical neck guide which houses the top portion of said rod (21 ) and a spring (55) that keeps it normally pressed downwards and further this part of the rod (21 ) has its top end sufficiently exposed for coupling with the contacts mechanism (1 1 ), while through the bottom portion, said rod (21 ) configures the shutter or frustum spigot (20) vertically protruded downwards and oriented to be housed inside the sealing seat ( 14) of the siphon tube (13), where said shutter cooperates to be vertically moved upwards or downwards by means of a circular diaphragm (56) that, through the central
- the electrical assembly ( 1 1 ) is illustrated in detail in figures 1 1 to 13, where it is noted that said assembly (1 1 ) is composed of a dielectric support (59) having an ordinary laid down "T"-shape, having its central branch terminal (60) coupled with the top end of the actuation rod (21 ), while its transversal branch has the terminals provided with drawer-type engagements (61) for the rear ends of the movable laminar contacts (62) that, on the one hand, are interconnected to the electrical feeding wires (F) while through the free ends, they are positioned under the inverted "L" fixed contacts (63), the top ends of which are horizontal and coplanarly facing against each other, while the bottom end protrudes vertically downwards crossing said wall (9) to form two coupling terminals (64) for the resistor (25), the third terminal of which is represented by a third flexible laminar contact (65) that, through the rear end, similarly crosses the wall (9), while through the front end, it is positioned under an extension or tab (66) of one of the "
- the dielectric support (59) is guided and its upward and downward movements are stably driven by means of a rear cut (73) and a pin (74) that vertically raises out of wall (9).
- the same modified electrical assembly ( 1 1 ) and all its actuation details, including the switch (67), may be inversely mounted according to a 180° displacement in relation to the central point defined by point (60).
- the shower operation is really simple as can be noted from figure 10, where it is seen that the water intake occurs through connection (8) invading the heating chamber (7) that, in turn, is normally kept flooded and, accordingly, the electrical resistor (25) is kept submerged, thus preventing its operation without the presence of water.
- the water intake in chamber (7) causes a pressure increase that is enough for the diaphragm (56) to be actuated.
- This actuation consists in its displacement upwards and accordingly the pin (21 ) is moved causing the contacts (62-63) to be closed and, in this condition, the electrical current passes from the wiring (F) to the resistor (25), causing it to operate.
- the selector (38), by means of its button (39) and the switch (67), allows switching among the several contacts (62-63-66-65), as well as the total insulation among them, that is to say, depending on the position, said contacts do not get into contact to each other even when the water intake occurs. In this condition, the device is turned off, however, in other positions, the selector can be moved to allow the device operation in two distinct conditions, winter or summer.
- This switching is carried out by means of button (39) that, when displaced to the right or to the left, causes the cover (38) and the switch (67) to move, and thus the device may be turned on/off or put into operation in the "summer or winter" temperatures.
- a different actuation mechanism for the contacts portion seen in greater details in figure 18, where it is noticed that said mechanism is composed of a movable dielectric support as a rocker (75) that, in a top view, has an ordinary laid down "Y"-shape, having its ends in different planes, wherein the highest plane is the sole and rear ramification (76), while the front and bifurcated plane (77) remains in a lower position, and further, said support or rocker (75) has its intermediate portion in a pivoting fashion (78), cooperating so that said support may swing raising and lowering its ends and for this purpose the rear end (76) is configured to be actuated by the actuation mechanism (51 ) that, for this purpose, has its rod (21 ) provided with a top extension (78) terminating in a self-locking head (79) which is coupled with an adequate hole existing in the correspondmg portion of said ramification (76) of the swinging support (75) and
- the same electrical actuation assembly defined by the rocker (75) and all its actuation details, including the switch (67), may be inversely mounted according to a 180° displacement in relation to the assembly central point (78).
- the shower operation is substantially the same of that of the previous version, as illustrated in figures 16, 17 and 18, where it can be seen that the water intake occurs through connection (8) invading the heating chamber (7) that, in turn, is normally kept flooded and, accordingly, the electrical resistor (25) is kept submerged, thus preventing its operation without the presence of water.
- the water intake in chamber (7) causes a pressure increase that is enough for the diaphragm (56) to be actuated.
- This actuation consists in its displacement upwards and accordingly the pin (21 ) is moved causing the rocker (75) to swing and close the contacts (85-63) and, in this condition, the electrical current passes from the wiring (F) to the resistor (25), causing it to operate.
- the selector ( 12), by means of its button (39) and the switch (67), allows switching among the several contacts (85-63-62-65), as well as the total insulation among them, that is to say, depending on the switch position, said contacts do not get into contact to each other even when the water intake occurs. In this condition, the device is turned off, however, in other positions, the selector can be moved to allow the device operation in two distinct conditions, winter or summer. This switching is earned out by means of button (39) that, when displaced to the right or to the left, causes the cover (38) and the switch (67) to move, and thus the device may be turned on/off or put into operation in the "summer or winter" temperatures.
