Single handle mixing valve

Abstract: The monoblock faucet comprises a faucet body (1) with its corresponding outlet pipe (2), including inside the body (1) a cartridge that determines the cold water and hot water distributing means , the cartridge being operated by a top external handle (3) provided with tiltable movement to open the faucet and provided with rotary movement between the limit positions that will correspond to the maximum cold water position and the maximum hot water position. The particularity of the faucet is that the handle (3) is mounted in such a way that in the maximum cold water limit position its longitudinal axis corresponds to the longitudinal axis of the pipe, in such a way that opening from said position will prevent the hot water heater from igniting, since it is far away from the position in which the outflow of hot water starts. It has, likewise, been foreseen that the holes of the body of the faucet that communicate with those that the cartridge must have to distribute the cold water, hot water or mixture thereof, in accordance with the positions of the handle and thereof of the cartridge, are tilted and the symmetric axis thereof is out of phase with regard to the symmetric axis of the pipe, an amplitude approximately half that determined between the two limit positions of the operating handle, so that it is also achieved that the maximum cold water position corresponds to the one in which the symmetric axis of the handle coincides with the one of the pipe. The faucet is completed with a flow adjustment device mounted transversely on the pipe, a device which consists of a screw that can be turned from the outside in order to place it in any position between a maximum flow limit and another minimum flow limit.

Description: The present invention refers to a monoblock faucet of the type in which the outflow of water is achieved by previously tilting an operating handle mounted on the body itself of the faucet upward, and in which the outflow of not water or cold water is achieved by partial turning of the operating handle. The faucet of the invention includes a series of improvements so that the opening of the faucet is done normally in the cold water position, thus preventing the hot water heater from igniting which is produced when the opening of the faucet is done in the hot water position. Including an outflow adjustment device so that the user can adjust the amount of flow , for the purpose of rationalising the water consumption to the needs of each moment, as also been provided for as an improvement. In all monoblock faucets a top operating handle that generally is operated towards one side or the other, with regard to the symmetric axis that coincides with the one of the faucet pipe, is mounted in all faucets in order to achieve cold water or hot water positions, in such a way that the outflow in any position requires the handle to be tilted upward. In other words, when the cited handle is aligned in the same vertical plane as the faucet pipe (position in which the user tends to leave it after each use for purposes of aesthetics) that position is considered the middle one between the cold water and the hot water, in such a way that if the faucet is opened in such a position, it is obvious that cold water and hot water will be mixed (the water comes out warm) which leads to the igniting of the hot water heater and the corresponding energy output. This energy output is unnecessary in the event that the user only requires cold water. DE-U-9106262 discloses a monoblock faucet, comprising a faucet body having an outlet pipe protruding therefrom, and a handle mounted on said faucet body. The handle is rotatably connected to said faucet body such that it can be rotated between a first limit position corresponding to a maximum cold water position and a second limit position corresponding to a maximum hot water position. The handle is further tiltably connected to the faucet body such that it can be tilted between a first position corresponding to a closed flow position and a second position corresponding to an open flow position. It can also be assumed that the faucet described in DE-U-9106262 comprises a cartridge which is disposed within said faucet body, the cartridge being connected to the handle such that when said handle is rotated between said first limit position and said second limit position said cartridge regulates the proportion of hot and cold water that is permitted to flow from hot and cold water inlet holes into the outlet pipe. Further, the symmetric axis of the handle is located in the vertical plane containing the symmetric axis of the pipe in the position corresponding to the maximum cold water position. DE-C-3402103 describes a monoblock faucet in which a bottom surface of the handle includes a polygonal housing for locking with respect to a rod of a distribution cartridge. On the other hand, in many occasions the user does not need the entire flow that the faucet provides, thus, unnecessary consumption is caused. Although there are valves or devices that can adjust the flow, it is no less certain that such means would necessarily have to be included in the faucet in the manufacturing process of the faucet; in other words, no adjustment device that can be included in faucets already manufactured or marketed is known. DESCRIPTION OF THE INVENTION The problems referred to above are solved by means of the present invention as claimed. The monoblock faucet object of the invention has a series of particularities foreseen to prevent the above cited inconveniences, in other words, so that the faucet is normally opened in the cold water position and according to a preferred embodiment so that the outflow can be adjusted in accordance with the user's needs. In this sense, a solution, as defined in appendent claims 10 to 19, consists of providing a specially designed operating handle, which is formed by a body whose contour is rather triangular with rounded vertexes, the corresponding contour tending to form a circular sector, which in the roundest end area has a short circular necked projected towards the bottom surface, through which it adapts to the body of the faucet, or else to an adaptation supplement provided in said body of the faucet. It has the particularity that on that bottom surface it has a square iron rod for coupling to the corresponding rod with a complementary shape, belonging to the water flow control body, said control body being called hereinafter the "cartridge." The handle coupling iron square rod has its symmetric axis slightly out of phase with regard to the symmetric axis of the element or rod on which it is coupled, in such a way that the rotation limit position towards one side, the symmetric axis of the handle coinciding with the symmetric axis of the pouring pipe, will correspond to the cold water maximum. Therefore, given that the handle tends to face the pipe and that position corresponds with the cold water outflow, it is obvious that the opening of the faucet will normally be done in the maximum cold water position, and the position in which the hot water starts to flow out will only be reached when the handle is clearly turned towards the left, prior raising the handle in order to open the faucet. This raising or tilting of the handle to open the faucet is done sideways and backwards, in other words, upward and to one side. The hot water maximum will be obtained when the handle turns toward the maximum limit opposite the cold water limit, the angle being about 110º from the initial limit or cold water outflow position, the hot water starting to flow out when it has been turned about 55º from the cited initial position. Another solution, as defined in appendent claims 1 to 9, consists of the two cold water and hot water intake holes in the pipe, instead of being made symmetric to the longitudinal axis of said pipe, they are made in such a way that the symmetry of such holes is regarding an axis displaced anglewise in terms of the longitudinal axis itself of the pipe. The cited angular outphasing will correspond to half the amplitude established between the two end positions of the operating handle, in such a way that in one of the end positions, the one corresponding to the cold water maximum, the symmetric axis of the handle coincides with the symmetric axis of the pipe, while the other position will be reached by turning the handle towards the hot water side, there being numerous possibilities to obtain different water temperatures between both limit positions. Therefore, the purpose that is achieved with these solutions is the same as the one cited above. Another advantage consists of the cited cold water and hot water passage holes being made in an inclined manner, so that based on the locking between the cartridge and the faucet body, the locking between the symmetric axis of the outlet holes of the cartridge also remain displaced anglewise with regard to the longitudinal axis of the pipe. The amplitude of the anglewise displacement is approximately equal to half the angle formed between the two limit positions of the handle. The symmetric axis of the handle remains aligned with the symmetric axis of the pipe in the cold water maximum position, in other words, as in the previous cases. On the other hand, it has been optionally foreseen that the cartridge have a supplement located between the base of the cartridge itself and the seat of the faucet body, whose supplement will have the respective inclined holes for the flow of water from the faucet body to the inside of the cartridge, obtaining the above cited angular positions, just like in the previous case. It has also been provided for that when the cartridge is of the type in which the water outflow is done freely from its own base, in such a case the above cited supplementary piece will be placed between the mouth of the water intake ducts and the seat of the faucet body. According to a preferred embodiment, the faucet includes a flow adjustment device, by means of which it is possible to control the outlet flow itself. The adjustment device is mounted on the water outlet pipe itself, in correspondence with the bottom part of said pipe, for the purpose of hiding its location. This adjustment device is structurally comprised of a threaded rod that has a reduction of area in correspondence with the center part, so that irrespective of the rotation position in which it is located the flow of water will be greater or smaller. This adjustment rod has an operating head that emerges partially outside the rod and has a diametral groove in order to facilitate changing the angular position of the same and thus the outlet flow of water can be controlled, with the particularity that in said head there is at least one anular groove to house an Or-ring seal, upon applying pressure against the smooth cylindric part of the threaded placement hole of the adjustment device. Advantageously, in the closed position of the adjustment device, the total flow of water is not prevented, but rather a minimum flow is allowed.

DESCRIPTION OF THE PREFERRED EMBODIMENT In view of the cited figures, the monoblock faucet object of the invention includes a faucet body (1) with its corresponding pipe (2) for the outflow of water. According to the first embodiment shown in figures 1 to 8, an operating handle (3) whose contour can be considered as rounded and triangular is mounted on the top of said faucet. Its shape is close to a circular sector with an opening (4) in correspondence with one of its corners and whose opening is provided so that the user insert one or two fingers in order to easily move said handle (3.) In the roundest part and in correspondence with the surface considered as the bottom one, said handle (3) has a cylindric shape (5) with a housing (6) determining a square iron rod for assembly and coupling of said handle (3) upon a rod (7) with a complementary shape provided for this purpose in the faucet body (1), a rod (7) which is connected to the corresponding cartridge (8), emerging with the top part of the faucet body (1) so that the handle (3) can be coupled. The assembly of this handle (3) on the faucet body is such that in a rotation limit position of the handle (3), the symmetric axis (9) of the handle coincides with the symmetric axis (10) of the pipe itself (2), as is represented in figure (3), this position corresponding to the maximum cold water point. As of this position the handle (3) can turn towards the left as represented in figure 4 to another limit position that will correspond to the maximum hot water point, the cited sector having amplitude of about 110º. The handle (3) mounted in such a way that it is projected backward with regard to the pipe (2) is seen in figures 5 and 6. The functioning is as follows: In the cold water limit position, which corresponds to figures 3 and 5, the symmetric axis (9) of the handle (3) is in alignment with the symmetric axis (10) of the pipe (2), this being the normal position after each use. Now then, in this position if the handle (3) is moved to open the faucet, it will have to be tilted backward and towards one side as shown in figure 8. The faucet will open and cold water will flow out. If one wants hot water, the handle (3) must be turned towards the other limit position as shown in figures 4 and 6, in such a way that from a rotation of about 55º hot water mixed with cold water starts to flow out. The maximum hot water is obtained in the rotation limit position opposite the initial position. As can be seen in figures 1, 3, 4, 5 and 6, the vertical axis of the handle does not correspond with the vertical axis of the rod (7) belonging to the cartridge (8)comprising the faucet opening device, in such a way, that the outphasing between the cited vertical axes is due to the slant that the rod (7) must have with regard to the square iron rod (6) on which it is mounted, when the opening operation is started. Another varied embodiment to achieve opening of the faucet is done normally in the maximum cold water position as is represented in figures 9 and 10, in which the corresponding cold water and hot water holes (13), provided for in the seat (14) partition of the faucet body (1) for the cartridge (8) are placed in such a way that the symmetric axis (15) of the same is out of alignment with regard to the symmetric axis (10) of the pipe (2), in such a way that this angular displacement between the axes (10) and (15) is approximately half the degrees between the end positions of the respective operating handle, in such a way that when the symmetric axis of the latter coincides with the symmetric axis (10) of the pipe (2), the position will correspond to the cold water maximum, and if in such a position the handle is tilted the faucet will open in the cold water position, and in order to obtain hot water it will be necessary to turn said handle as already stated above. In other words, by virtue of this positioning of the water intake holes (13), when the handle is aligned with the pipe (2) cold water will flow out, if the handle is tiled and the faucet opens correspondingly. In these figures 9 and 10 the holes or openings (16) likewise made in the base or diametral partition (14) of the faucet body (1) can be seen. The pivots that emerge from the corresponding cartridge (8) will be positioned in holes (16) so that the cartridge (8) is locked with regard to the faucet body (1.) In a preferred embodiment shown in figures 11 to 16, one can see how the cartridge (8) includes a base (17) whose corresponding hot water and cold water holes (18) are inclined, holes (18) which are the ones that determine the flow of water from the faucet body (1), in other words from the holes (13) to the inside of the cartridge (8), in order to flow from here through the pipe (2), as is clearly represented in figures 11 and 12. One can also see the locking holes (16) for the pivots (19) of the base itself (17) of the cartridge (8), where the symmetric axis (15) of the holes (18) is displaced anglewise with regard to the symmetric axis (10) of the pipe (2), this anglewise displacement being approximately half the angle that determines the portion corresponding to the limit positions of the operating handle, the symmetric axis of said operating handle coinciding with the axis (10) of the pipe (2) in the maximum cold water position, in other words, exactly identical to the case cited above. In figures 13 and 14 one can see how between the seat (14) base of the faucet body (1) and the cartridge itself (8) a supplementary piece (17') provided with the corresponding inclined holes (18) as in the previous case, is located, carrying out the locking between the cartridge (8) and the supplementary piece (17'), as well as between the latter and the faucet body (1), by means of the respective holes (16) and stubs (19.) In figures 15 and 16 the faucet is shown with a cartridge (8) of the type whose water outflow is done freely from the base itself (20) of the cartridge (8), in such a way that in this case the supplementary part (17'') likewise has its holes (18) inclined and it is also locked by means of holes (16) and stubs (19). The holes (18) of the supplementary part (17'') lead into the duct (21) through which there is communication between the supplementary part (17'') and the inside of the cartridge (8.) Just like in the previous cases the symmetric axis (15) of the holes (18) is displaced anglewise with regard to the symmetric axis of the pipe (2.) In all of the cited cases, when the symmetric axis of the operating handle is aligned up with the symmetric axis (10) of the pipe (2), it will correspond to the maximum cold water position, whereby the opening of the faucet in said position will never lead to the igniting of the hot water heater, with the subsequent energy saving which is what is sought on the grounds of all of the described embodiments. On the other hand, the faucet can be completed with a flow adjustment device, which is placed upon the bottom surface of the pipe itself (2) as is seen in figure 17, in such a way that the flow adjustment element or device has a head (22) with a diametral groove in order to move the same and operate said adjustment device and thus manage to control a larger or smaller outflow of water. In this sense, it has been foreseen that the pipe (2) of the faucet includes inside a transversal partition (23) that has a center break or middle opening (24), in which a rod (25) that pivots around its own axis is situated. The rod has two side recesses (26) that define a diametric plate (27) which constitutes the element that limits the flow of water to adjust outlet flow. The middle opening (24) of the transversal partition (23) is defined by a side hole (28) made in the pipe itself (2), hole (28) which is threaded inside for the purpose of receiving the outer thread of the rod itself (25), whose head (22), as has been said above, slightly sticks outside the pipe (2), specifically through the bottom surface of the latter so that it can be moved by means of its diametral groove (24), by means of a suitable tool, such as a coin, screwdriver, etc. This diametral groove (29) of the head (22) corresponding to the pivoting cod (25) is advantageously coplanar to the diametral plate (27) defined by the side recesses (26) of the rod itself (25), so that its position visually indicates the position of the diametral plate (27) in the inside of the pipe (2), thus making the control operation easier. The head (22) has an annular throat (30) in which a seal (31) adjusted to the diameter of the mouth of the side hole (28) that defines its housing, is located. Therefore, by means of rotating the rod (25) by means of its head (22), as has been said above, it is possible to place the plate (27) in a position coplanar to the partition (23), thus determining the minimum flow position, as corresponds to figures 20 and 21, while when the plate (27) remains transversal to the partition (23), as represented in figures 18 and 19, then the faucet provides the maximum flow of water, with the particularity that between these limit positions the rod can be placed in any of the multiple middle positions and thus the flow can be adjusted in accordance with the user's own needs or desires, all for the purpose of rationalising the water consumption to the real needs of each case.
