Description

DEFLECTION VALVE FOR SPRINKLER SPRAY SYSTEMS FIELD OF THE INVENTION This invention relates generally to the field of valves and more particularly to a diverter valve that can be installed between a sprinkler inlet and a sprinkler nozzle to allow quick connection and disconnection of a manually held sprinkler used to clean sprinkler compartments. and bathrooms.

BACKGROUND OF THE INVENTION The use of accessories in shower plumbing systems has been well known in the art for some time. Typically, these fittings are comprised of a flexible conduit that can be coupled adjacent to a sprinkler nozzle at one end of the conduit to allow fluid communication with a sanitary nozzle secured to the second end of the conduit. These chiflones are intended for daily use and may include manually held spray nozzles to rinse during showering or dental syringes for oral hygiene. Accessories such as those referred to above frequently integrate valve systems that include coupling components and diverting valves. Because these accessories are intended for daily use in conjunction with the act of showering and / or hygiene, they are permanently coupled adjacent to the shower nozzle. In addition, for these devices that are intended to be used simultaneously with the shower nozzle, the diverter valve may allow a partial flow of water to the shower nozzle and a partial flow of water to the fitting. The patents listed below are representative of the prior art. The patent of the U.S.A. No. 4,043,337, issued to Baugher, teaches a dental syringe attachment that includes a diverter valve attached in line between a shower nozzle and a water supply tube. The bypass valve includes a coupling to permanently attach the dental syringe to the valve. In addition, the valve includes a rotatably mounted portion that directs water flow to the shower nozzle when it rotates to a first position and directs water flow to the syringe when turned to a second position. The U.S. Patent No. 4,265,229, issued to Rice et al., Also discloses an oral hygiene apparatus for use with showers. Rice teaches a hollow valve body that connects the inlet tube of the shower with the shower nozzle. A permanently attached hose, advancing from an orifice regulated by needle valve in the valve body, is connected to a nozzle applicator. The needle valve is manually rotated to control the flow of water into the hole through the hose and out of the nozzle. In this case, the needle valve works only to divert a portion of the water flow to the shower nozzle so that water flows from both the shower nozzle and the nozzle.

Another oral hygiene apparatus is taught in U.S. Pat. No. 4,793,331, issued to Stewart. This device includes an oral syringe permanently attached in fluid communication with a shower nozzle by means of a valve assembly. The valve assembly contains a manually adjustable valve stem that controls a bypass valve. The threaded valve stem can be rotated to a first position to allow water to flow to both parts, the shower nozzle and the nozzle. Alternatively, in cases of low pressure, the valve stem can be further rotated until the flow of water to the shower nozzle is completely diverted to the syringe nozzle. Finally, the Patent of the U.S.A. 3,471, 872, issued to Symmons, teaches a spray nozzle permanently attached to a bath tube or shower attachment by means of a flexible conduit. The accessory contains a bypass valve that diverts the water flow to the nozzle in response to a pressure drop created by the nozzle opening. When the mouthpiece is closed, a loading pressure forces the valve open and allows water flow to the shower nozzle. When the nozzle is open, a backpressure is created on the valve, forcing it to close and terminate the flow of water to the shower nozzle. No water flows out of the shower nozzle as water passes through the nozzle. However, when the nozzle is closed, the valve will be pressed again to open and the flow of water to the sprinkler nozzle will resume. Each of the devices mentioned above is useful for the purpose for which it was designed, however, none is well suited for accessories used to clean shower compartments or other bathroom accessories. For example, each of the above described devices teaches permanent attachment of a flexible conduit to some type of bypass valve assembly. Permanent fixation is necessary since these devices are intended to be used on a regular basis, that is, daily. However, such configurations are not conducive to accessories used to clean shower compartments or other bathroom accessories because these types of accessories are required on a less frequent basis, that is, only during cleaning. When not in use, these cleaning accessories can inhibit the use of the shower nozzle. Additionally, some of the devices described above divert only a portion of the water flow to the fittings, so that the water continues to flow also out of the shower nozzle. When cleaning bathroom fixtures, especially shower compartments, it would be inconvenient for the water to continue to flow out of the shower nozzle because people who have entered the shower may get wet to clean the area. In addition, the limited scale of movement of a typical sprinkler nozzle and the limited head pressure in the sprinkler nozzle make it difficult to direct a stream of water to all areas of a sprinkler compartment for cleaning purposes. Even when the water can be directed to a desired area, the pattern of sprinkling the water from a sprinkler nozzle makes it difficult to contain the sprinkler to a limited area. For example, when shower doors or upper portions of a shower compartment are cleaned, a typical shower nozzle can not be positioned to direct a rinse spray to these areas. In this way, these areas can remain without rinsing or water must be transported to these areas using some other means such as a container. Therefore, it would be desirable to have a bypass valve assembly and cleaning accessory that could allow the cleaning attachment to be easily removed and stored until required. Additionally, it would be convenient to provide a bypass valve that cuts off the flow of water to the shower nozzle when the accessory system is connected. Finally, it would be convenient to provide a rinsing system that allows the water to be selectively directed to an area that is to be rinsed.

BRIEF DESCRIPTION OF THE INVENTION This invention relates to a system of cleaning accessories that can be coupled between a water outlet and a shower nozzle. The system includes a bypass valve, flexible conduit, a coupling at a first end of the conduit for joining the conduit in fluid communication with the diverter valve and a nozzle attached to a second end of the flexible conduit. In a first embodiment, the diverting valve is comprised of a valve housing having a water inlet, a first outlet and a second outlet; a fixing housing for coupling with the flexible conduit; and a valve slide. The valve slide moves in an annular cavity located inside the valve housing. The annular cavity allows fluid communication between the water inlet, the first outlet and the second exit. A normal shower nozzle can be attached to the first outlet. In the second outlet, the fixing housing is fixed to the valve housing to secure the valve slide in the annular cavity while allowing fluid communication between the fixing housing and the annular cavity. A spring urges the valve slide in a first position where the valve slide seats adjacent to the fixing housing. In this first position, the valve slide seals the second outlet allowing fluid communication only between the valve inlet and the first outlet so that water flow is directed through the shower nozzle. When the flexible conduit is coupled with the fixing housing, the coupling urges the valve slide towards a second position in the annular cavity. In this second position, the valve slide seals the first outlet, allowing fluid communication only between the valve inlet and the second outlet. In this second position, the fluid flow is diverted from the shower nozzle to the fixation until the flexible conduit disengages. In another embodiment, the flexible conduit is directly coupled to a shower nozzle that is comprised of an external box attached to an internal box to define a flow chamber therebetween. This flow chamber works to direct water flow out of the shower nozzle through shower outlet holes. The inner box also defines an internal cavity in which a valve slide is slidably mounted. Perforations at the proximal end of the interior cavity allow fluid communication between the cavity and the flow chamber. A fixing housing engages with the inner box to restrict the valve slide to axial movement within the internal cavity. The fixation housing is the same as described above for the first embodiment, so that the fixation housing can be used in any mode, resulting in cost savings. A spring urges the valve slide towards a first position in the internal cavity where the valve slide seats against tabs on the fixing housing. In this first position, the valve slide seals the fixing housing, allowing fluid flow only towards the proximal end of the internal cavity, so that the flow of water is directed through the outlet orifices of the shower. However, when the flexible conduit engages the fixing housing, the coupling urges the valve slide to a second position in the internal cavity. In this second position, the valve slide sits inside the inner box and seals the proximal end of the internal cavity so that the fluid flows only through the fixing housing. Because the fixing housing is in fluid communication with the flexible conduit, the water flow is directed through the flexible conduit towards the fixing. The fluid flow will continue to be diverted in this manner from the shower nozzle to the fixation, until the flexible conduit disengages.

DESCRIPTION OF THE PREFERRED MODALITIES In the detailed description of this invention, like numbers are used to designate similar parts throughout. To simplify the description, several items of the equipment, such as fasteners, accessories, etc., are omitted. However, those skilled in the art will understand that such conventional equipment can be used at will. A deflection valve is shown in FIGS. 1 and 2 and is generally designated 10. The diverting valve 10 is comprised of a valve housing 20, a fixing housing 30, a valve slide 40 and a spring 50. valve housing 20 is provided with a water inlet 21, a first water outlet 22, a second water outlet 23 and an annular cavity 24 that allows fluid communication between the water inlet 21, the first water outlet 22 and the second water outlet 23. The first water outlet 22 is configured to be attached to a normal shower nozzle (not shown) and the water inlet 21 is configured to be attached to a normal water supply tube (not shown) . The second water outlet 23 is configured to receive the fixing housing 30 so that when the fixing housing 30 is matched with the valve housing 20, the O-ring 32 provides sealing contact between adjacent portions of the fixing housing 30. and the valve housing 20. The fixing housing 30 is defined by a first end 31, a second end 33, a continuous hole 34 and an internal shoulder 35. In the preferred embodiment, the inner diameter of the first end 31 is equivalent to diameter of the annular cavity 24. The second end 33 is configured to receive the fastening element 90 which includes a coupling 91 fixed to a flexible conduit 92. Although the coupling 91 can take many forms, the preferred embodiment comprises an adapter 95, a sealing ring 94 and an O-ring 96. The sealing ring 94 is secured to the adapter 95 by the flexible conduit 92 so that when the coupling 91 is seated in sealing contact within the second end 33, the flexible conduit 92 is in fluid communication with the valve housing 20. The O-ring 96 increases the sealing contact between the coupling 91 and the fixing housing 30 The valve slide 40 is comprised of a first end 41 and a second end 42 and is slidably located in the annular cavity 24 of the valve housing 20. The first end 41 is provided with a plurality of guide extensions 43 for guiding the movement of the valve slide 40 in the annular cavity 24 without inhibiting fluid flow therethrough. The second end 42 is also provided with a plurality of extensions 45. The plurality of extensions 43 on the first end 41 of the valve slide 40 does not inhibit fluid flow between the water inlet 21 and the water outlet 22. Similary, the plurality of extensions 45 on the second end 42 of the valve slide 40 do not inhibit the flow of fluid between the water inlet 21 and the flexible conduit 92. In addition to receiving the fastener 90 to allow fluid communication between the flexible conduit 92 and the valve housing 20, the fixing housing 30 is fixed to the second water outlet 23 of the valve housing 20, so that the fixing housing 30 restricts the valve slide 40 within the annular cavity 24 The spring 50 also travels within the annular cavity 24 and urges the valve slide 40 against the shoulder 35 so that the valve slide 40 sits in sealing contact within the first end 31 of the fixing housing 30. In In the preferred embodiment, the O-ring 44 is used to increase sealing contact between the valve slide 40 and the fixing housing 30 when the valve slide 40 is engaged. enter a first position. When the fixing element 90 is coupled to the second end 33 of the fixing housing 30 (as shown in Figure 2) by means of the coupling 91, the coupling 91 makes contact with the extensions 45 of the valve slide 40 and drives the valve slide 40 along the annular cavity 24 to a second position. In this second position, the valve slide 40 is in sealing contact with the valve housing 20, specifically, the wall defining the annular cavity 24. Again, the O-ring 44 increases the sealing contact between the wall the annular cavity 24 and the valve slide 40. Because the internal diameters of the annular cavity 24 and the first end 31 of the fixing housing 30 are equivalent, the O-ring 44 can provide sealing contact in either of the two , the first position or the second position. Although the coupling 91 can take many forms, in one embodiment, the second end 33 of the fixing housing 30 is provided with diametrically opposed hook-shaped recesses, 36a, 36b, to receive opposite tabs, 93a, 93b, arranged on the outer surface of the closing ring 94 (see figure 3). The angle of each recess 36 is preferably ten degrees to ensure that the coupling 91 does not inadvertently separate from the diverter valve 10 if the flexible conduit 92 is twisted. The contact surface of each reed 93 is similarly angled to increase the assembly. with each recess 36. Additionally, the coupling 91 can be provided with at least one flange to assist in the connection and disconnection of the fastener 90. In a preferred embodiment illustrated in Figure 3, the closure ring 94 is provided. with two tabs 94a, 94b, which can be comfortably held for connecting and disconnecting the fastening element 90. Now the operation of the diverting valve 10 of figures 1 and 2 will be described. In figure 1, the valve slide 40 is represented in the first position, that is, the hose fixing element 90 is not connected. In FIG. 2, the valve slide 40 is shown in the second position, that is to say, the hose fixing element 90 is connected. When the valve slide 40 is in the first position, flow of water entering the inlet valve 21 is directed towards the annular cavity 24. Because the spring 50 urges the valve slide 40 against the shoulder 35 so that there is sealing contact between the fixing housing 30 and the valve slide 40, the fluid flow passes through the annular cavity 24 and out of the first water outlet 22. The plurality of extensions 43 on the valve slide 40 does not inhibit fluid flow between the water inlet 21 and the first water outlet 22, but only serves to guide the valve slide 40 when sliding in the annular cavity 24. When the fastener 90 is coupled to the valve deviation 10, the adapter 95 of the coupling 91 makes contact with the extensions 45 of the valve slide 40 and urges the valve slide 40 to move in opposition to the direction of the force provided by the spring 50. More specifically, when the tongues 93a, 93b are completely seated in the holes configured in hook form 36a, 36b, the valve slide 40 is maintained in the second position described above. In this second position, the valve slide 40 is in sealing contact with the wall defining the annular cavity 24 so that the water entering through the water inlet 21 is directed through the fixing housing 30 and towards the flexible duct 92 which is coupled in sealing contact with the fixing housing 30 by means of the coupling 91. Because the internal diameters of the annular cavity 24 and the first end 31 of the fixing housing 30 are substantially the same, it can sealing contact between either of the two, the valve slide 40 and the fixing housing 30 (when the fixing element 90 is not coupled to the diverting valve 10) or the valve slide 40 and the wall of the cavity, are maintained. annular 24 (when the fixing element 90 is coupled to the diverter valve 10). The diverting valve 10 can be made of any normal material, such as molded plastic or molten metal. In Figure 4, another embodiment of the deflection valve described above is shown. Again, the diverter valve 60 is comprised of a valve housing 62, a valve slide 63 and a spring 50. The valve housing 62 is similar in configuration to the valve housing 20 of the first embodiment (see FIG. 1). ) except that the valve housing 62 is a single piece provided with a hollow shaped hook 67 for receiving the coupling 72 of the fastener element 70. Additionally, the valve slider 63 is constrained and guided within the internal cavity 64. by means of valve stem 65 (which is held in place by means of fastener 66). Therefore, the fixing housing described in the first embodiment is integrated as part of the one-piece valve housing in the second embodiment. Returning to Figure 5, another embodiment of the invention is shown. In this embodiment, a sprinkler nozzle 100 is provided with a deflection system similar to that of the first mode, however, the fastener 90 is directly coupled to the sprinkler nozzle 100. Specifically, an external case 120 is attached to an inner box 130 for defining between them a flow chamber 165. A valve slide 150 is slidably located within a cavity 180 defined by an inner box 130. A fixing housing 30 is mounted to the inner box 130 to restrict the movement of the valve slide 150 within the cavity 180 between a first position (figure 6) and a second position (figure 7). In the first position, the valve slide 150 deflects the water through the flow chamber 165. In the second position, the valve slide 150 deflects the water towards the fixing element 90. More specifically, the inner box 130 is configured to define an axial bore 131 extending from a first end 132 to a second end 133 so that fluid can flow axially through the interior of the inner box 130. Further defined by the sides of the inner box 130 is located an internal cavity 180 which is disposed between the first and second ends 132, 133, so that the axial hole 131 is in fluid communication with the internal cavity 180. The proximal end of the cavity 180 is provided with a plurality of openings 135 that allow fluid communication between the internal cavity 180 and the chamber flow 165. The inner box 130 may also be provided with an inner circumferential groove 136 for receiving a washer 170 and an inner circumferential groove 137 for receiving the O-ring 171. The inner box 130 is also provided with an outer circumferential flange 138 that it is sealingly coupled with the outer case 120 to also define the flow chamber 165. A plurality of openings 149 are disposed along the flange 138 to allow fluid communication between the flow chamber 165 and the outside of the shower nozzle 100. The outer case 120 has a first end 121 with a first diameter and a second end 122 with a second diameter smaller than the first diameter. The water inlet 1 10 in fluid communication with the axial hole 131 is seated in the second end 122 of the outer box 120. In the preferred embodiment, the water inlet 1 10 has a spherical shape at one end to allow ball and basin connection with the outer box 120. A bushing box 113 and an O 1 14 ring settle within the second end 122 of the outer box 120 to allow ball and basin attachment of the water inlet 1 10. This type of ball and basin union allows the sprinkler nozzle 100 to be rotated universally in relation to a normal water supply tube (not shown). The valve slide 150 is comprised of a tubular shaped seal 151 having a first end 152 and a second end 153. The valve slide 150 is provided with an interior passage 154 having a first portion 155 and a second portion 156. The first portion 155 is aligned along the axis of the obturator 151 and extends from the first end 152. The second portion 156, which extends radially from the first portion 155 and has a channel shape, is in communication with fluid with the outer surface of the obturator 151. A first flange 157 is disposed circumferentially on the surface of the obturator 151 above the second portion 156 of the interior passage 154, and a second flange 158 is disposed circumferentially on the surface of the obturator 151 below of the second portion 156 of the interior passageway 154. The first flange 157 is provided with a slot 172 for receiving the O-ring 174. Similarly, the second flange 158 is provided with a slot 173 for receiving the lower O-ring 175. The first end 152 of the valve slide 150 extends at the first end 132 of the axial bore 131 allowing communication of fluid between the inner passage 154 and the hole 131, while restricting the axial movement of the valve slide 150 within the cavity 180. The O-ring 171 sits in the notch 137 to provide sealing contact with the first end 152 as it slides into the hole 131. In addition, the second end 153 of the valve slide 150 is provided with a plurality of axially extending projections 105. In the preferred embodiment, the fixing housing 30 is the same as that used in conjunction with the bypass valve 10 (described above and shown in Figure 1) and will not be described further. The use of the same fixation housing in various modalities minimizes manufacturing costs. The fixing housing 30, when incorporated with the shower nozzle 100, is attached to the inner box 130 at a second end 133 of the hole 131 to also define an internal cavity 180 and restrict the valve slide 150 within the cavity 180 The spring 163 is axially mounted within the cavity 180 and urges the valve slide 150 against the shoulder 35 so that the second flange 158 of the valve slide 150 is seated in sealing contact within the first end 31 of the valve housing. fixing 30 and sealing contact is provided by means of the lower O-ring 175 or the flange 158. In this first position, the second portion 156 of the inner passage 154, is in fluid communication with the internal cavity 180. When the element of fixing 90 engages the second end 33 of the fixing housing 30 (see Figure 7) by means of the coupling 91, the adapter 95 of the coupling 91 makes contact with the extensions 105 of the valve slide 150 and urges the valve slide 150 axially into the cavity 180 to a second position. In this second position, the first flange 157 of the valve slide 150 is adjacent to the wall defining the internal cavity 180 so that sealing contact is provided by means of the O-ring 174 between the first flange 157 and the inner housing 130. In this second position, the second flange 158 does not seat with the inner flange 35 of the fixing housing 30. Therefore, the second portion 156 of the interior passage 154 is in fluid communication with the flexible conduit 92 of the fastening element 90 by means of the fixing housing 30. The washer 170 serves to retain the O-ring 171 in place while the valve slide 150 moves from its second position in cavity 180 to its first position in cavity 180. In addition, washer 170 serves as a base against which spring 163 can be spliced. The operation of the nozzle will be described below. of sprinkler 100 of figure 5. When the valve slide 150 is in the first position as shown in figure 6, the flow of water entering through the water inlet 110 is directed towards the axial hole 131 which is located in fluid communication with the inner passage 154. In its first position, that is, without the fastener element 90 coupled to the shower nozzle 100, the valve slide 150 is solid. against the shoulder 35 and there is sealing contact between the lower O-ring 175 and the fixing housing 30. In this way, the flow of water out of the second portion 156 of the inner passage 154 travels through the openings 135. , located at the proximal end of the cavity 180, and towards the fluid chamber 165 where the water flow is directed out of the shower nozzle 100 through the openings 149. When the fixing element 90 is coupled to the shower nozzle 100 as shown in Fig. 7, adapter 95 of coupling 91 makes contact with the extensions 105 of valve slide 150 and urges valve slide 150 to move in opposition to the direction of the force provided by the spring 163. More specifically, when the tongues 93a, 93b, have fully seated in the hook-shaped recesses 36a, 36b (described above and shown in Figure 3), the valve slide 150 is has in the second position. In this second position the valve slide 150 is seated within the cavity 180 of the inner box 130 so that sealing contact is provided between the valve slide 150 and the inner housing 130 by means of the upper O-ring 174. this way, the water flowing out of the inner passage 154 moves around the extensions 105, through the hole 34 of the fixing housing 30, through the adapter 95 and towards the flexible conduit 92. The individual components of the nozzle Sprinkler 100 can be manufactured from any normal material, such as molded plastic or molten metal. Although the invention has been described in considerable detail through the figures and the foregoing discussion, one skilled in the art can make many variations and modifications without departing from the spirit and scope of the invention, as described in the following claims.
