Description

  The present invention relates to a water-saving toilet water-saving device that saves water by advancing the closing timing of a rubber float valve in a water tank installed in a water-washing tray.

  For example, as shown in FIGS. 9 and 10, this type of flush toilet water-saving device is used as an auxiliary tool for a rubber float valve 32 that opens and closes a drain port 31 in a water tank 30 installed in the flush toilet. The rubber float valve 32 is lifted when the pulling line 34 is pulled upward by the operation of the lever 33 to open the drain port 31, and the water filled in the water tank 30 is transferred from the drain port 31 to the toilet. And leaked. At that time, the rubber float valve 32 closes the drain port 31 at a predetermined timing by its own weight from the raised position. However, the timing when the rubber float valve 32 closes the drain port 31 may be too late with respect to the outflow of the required water amount, and there is a tendency that water saving is desired. Therefore, conventionally, a flush toilet water-saving device 37 is attached to a portion of the rubber float valve 32 to which the pulling line 34 is connected, and the rubber float valve 32 closes the drain port 31 to the water-saving toilet water-saving device 37. The amount of water flowing out is reduced by speeding up by the weight.

  As the water-saving device 37 for the flush toilet, there are a cable passage opening through which the lifting cable 34 is passed, a cable entry / exit slit that reaches the outer periphery from the cable passage opening, and pin insertion holes provided on both sides of the slit. There has been proposed a combination of a water-saving tool main body and a detachment prevention pin that has both ends passed through the pin insertion holes and closes the slit in a state of straddling the slit entering and exiting (for example, Patent Document 1). reference).

  Conventionally, water saving tools for flush toilets as shown in FIGS. 11 and 12 are also known. As shown in FIG. 11, the flush toilet water-saving device 37 includes a disk-shaped water-saving device body 38 and an auxiliary member 39 that is overlapped and integrated with the water-saving device body 38. In the water-saving device main body 38 and the auxiliary member 39, the rope passages 40 and 41 through which the pulling ropes 34 are passed are respectively opened at the central portions thereof, and the ropes reaching the outer periphery from the rope passage openings 40 and 41. The slits 42 and 43 are formed, and a pair of screw holes 44 are formed at opposite positions in the radial direction on both sides of the cord entry / exit slit 42 of the water-saving device main body 38, and the auxiliary member 39 has a cord. A pair of insertion holes 45 are formed at opposite positions in the radial direction on both sides of the slit 43.

The above-mentioned flush toilet 37 for flush toilets passes the pulling line 34 (FIG. 9) through the line entry / exit slits 42, 43 through the line passage openings 40, 41, and then, as shown in FIG. The entrance / exit slits 42 and 43 are set at relative positions opposite to each other in the radial direction so that the auxiliary member 39 is fitted into the recess 46 of the water saving device main body 38, and each insertion hole 45 is matched with each screw hole 44. Then, the fixing screw 47 is screwed into the screw hole 44 from the insertion hole 45 and fastened, whereby the water saving tool main body 38 and the auxiliary member 39 are integrated to assemble the water saving tool 37, and this water saving tool 37 is attached to the lifting line 34. In this attached state, the cord entry / exit slits 42, 43 are closed by the auxiliary member 39 and the portion of the water saving device main body 38 where the cord entry / exit slits 43, 42 do not exist. It is possible to reliably prevent the lifting rope 38 passed through the attachment holes 0, 41 from coming into and out of the slits 42, 43.
JP-A-9-27966

  However, in the former water-saving toilet water-saving device, the belt-shaped detachment pin is bent at two places in the state where the rope 34 is pulled up through the cable passage opening of the main body, and both ends thereof are formed. Through the pin insertion hole of the main body, and both ends of the pin insertion hole must be bent inward and attached to the main body so as to prevent it from coming off. Assembly and installation work must be done. In addition, since the retaining pin only holds the slit by holding the state of being plastically deformed by bending at the time of attachment, the above-mentioned deformation state is achieved by repeatedly moving the water tank 30 up and down in water. In this case, there is a possibility that the water-saving device 37 for the flushing tray may come off the pulling line 34.

  On the other hand, the latter water-saving toilet 37 has a water-saving device main body 38, an auxiliary member 39, and two fixing screws 47. Therefore, the cost increases as the number of parts increases. Further, when attaching the water-saving toilet 37 for the flush toilet, the pulling line 34 was passed through the line entry / exit slits 42 and 43 of the water-saving tool main body 38 and the auxiliary member 39 into the cable passage openings 40 and 41. After that, the auxiliary member 39 is positioned in a relative arrangement in which the slits 42 and 43 entering and exiting from each other are opposed to each other on both sides in the radial direction and fitted into the recess 46 of the water-saving device main body 38, while maintaining this state. A complicated assembly operation of screwing the two fixing screws 47 into the screw holes 44 is required. Therefore, there is a problem in that the flush toilet water-saving device 37 requires a complicated operation and is not easily attached. That is, since all the conventional water-saving devices for flush toilets are configured to be attached to the lifting rope by assembling and integrating a plurality of parts, they cannot be easily attached.

  The present invention has been made in view of the above-described conventional problems, and provides a water-saving device for a flush toilet that can reduce the number of parts and reduce costs, and can be easily attached to a lifting rope by a one-touch operation. The purpose is to do.

  In order to achieve the above object, the water-saving toilet flushing device of the present invention is attached to a pulling rope connected to a rubber float valve that opens and closes a drain outlet in a water tank to accelerate the closing timing of the rubber float valve. In the thing, it has a rope passage opening at the center, and a water saving tool body provided with a slit reaching the outer periphery from the rope passage opening, and is superposed on the upper surface of the water saving tool body and coupled to the water saving tool body. An auxiliary member provided with a slit that reaches the outer periphery from the cable passage opening corresponding to the slit, and has a cable passage opening corresponding to the cable passage opening in the central part, and the auxiliary member The tip having a free end that allows the pull-up line to be introduced into the line passage opening from the slit and prevents escape from the line passage opening to the slit. A retaining piece is integrally formed, and a plurality of elastic locking claws extending downward are integrally formed on the auxiliary member, and the water-saving tool body corresponds to each elastic locking claw. A plurality of locking holes are provided, and each elastic locking claw portion is inserted through the corresponding locking hole from above, and each elastic locking claw portion is elastically engaged with the locking hole. Thus, one feature is that the auxiliary member is coupled to the water-saving device main body.

  The water-saving device for a flush tray of the present invention is also provided in a water-saving toilet water-saving device that is attached to a pulling rope connected to a rubber float valve that opens and closes a drain port in a water tank and accelerates the closing timing of the rubber float valve. In the central part, the cable passage opening is provided with a slit that reaches the outer periphery from the cable passage opening so that the cable passes through both the longitudinal direction and the direction perpendicular thereto with play. The water-saving tool body, and the upper surface of the water-saving tool body are overlapped and coupled to the water-saving tool body, and has a cable passage opening corresponding to the cable passage opening in the central part, and corresponding to the slit An auxiliary member provided with a slit reaching the outer periphery from the cable passage opening, and the wire passage opening and the slit of the auxiliary member are the opening diameter and the slit of the cable passage opening of the water-saving device body Having an opening edge with a thickness that is smaller than or equal to the constriction width of the constricted portion of the cord continuous in the longitudinal direction and having a constricted portion repeatedly, and extends downward to the auxiliary member. A plurality of elastic locking claws are integrally formed, and a plurality of locking holes are provided in the water-saving device main body corresponding to the elastic locking claws, and each elastic locking claw is provided. The auxiliary member is coupled to the water-saving device main body by inserting each elastic locking claw portion elastically into the locking hole. It has another feature.

  In this case, the auxiliary member has a recess having a size corresponding to the cable passage opening and the slit of the water-saving device main body, and is provided so that the opening edge extends inside the recess. it can.

  Moreover, it is preferable that the auxiliary member in each of the above inventions is an integrally molded product of synthetic resin.

  According to one feature of the water-saving device for flush toilets of the present invention, it is only provided with two parts of the water-saving device main body and the auxiliary member. Since it is only necessary to perform a one-touch operation to push the water into the corresponding locking hole of the water-saving device main body from above, the cost can be reduced as the number of parts and the number of assembly steps are reduced. Also, when attaching to the rubber float valve through the lifting rope, after inserting the lifting rope into the slit from the outer periphery, pressurize it in the direction to pull it into the rope passage opening, and place the elastic retaining piece inward When elastically deformed so as to be bent, it is passed through the cable passage opening, the deformed elastic retaining piece returns to its original shape by its own restoring force, closes the slit, and the line of the lifting cable passes The mouth is prevented from coming off. Therefore, unlike the conventional flush toilet water saving device, this flush toilet water saving device is different from the one that attaches to the pulling rope by assembling multiple parts, and the single flush toilet water saving device can be easily operated with one touch operation. Can be pulled up and attached to the rope.

  According to another feature of the water-saving device for a washing tray of the present invention, the rope passage opening of the auxiliary member and the opening edge of the slit are used instead of the elastic retaining piece in the case of the one feature. By having a thickness smaller than the opening diameter of the rope passage opening of the main body and the opening width of the slit, and having a narrowed portion repeatedly and having a constricted width that is substantially equal to or less than the narrowed width of the continuous narrowed portion of the rope. , While allowing easy access to the cable passage opening through the slit at the constricted portion of the cable, while suppressing the play in the direction perpendicular to the longitudinal direction of the cable at the cable passage and the slit to the cable, the cable It is possible to suppress the movement of the auxiliary member in the longitudinal direction between the non-constricted part larger than the constricted part size of the rope and to the extent necessary by selecting the size of the opening diameter and the opening width. Open and close Create and feed, by the flow of water during draining calms water saving device against rope or rubber float valve, to be allowed to more stably exert a water saving effect, no occurrence of abnormal noise.

  In addition, when the opening edge is provided so as to extend inside a recess having a size corresponding to the line passage opening and slit of the water-saving device main body in the auxiliary member, water is saved at a portion other than the opening edge. The coupling strength with the tool body is ensured, and the play between the rope and the water saving tool can be suppressed without impairing the ease of entering and exiting the rope passage through the slit of the rope.

  Further, if the auxiliary member is an integrally molded product of synthetic resin, it is possible to suitably form the elastic retaining piece and the elastic locking claw portion that are required to have the required elastic force, and to achieve high accuracy. It can be formed in a simple size and can be coupled in a state where it is fitted to the water-saving device body without rattling.

  Hereinafter, the best mode for carrying out the present invention will be described in detail with reference to FIGS. FIG. 1 is an exploded perspective view showing a water-saving device for a flush toilet according to the preferred embodiment of the present invention, and FIG. 2 is a perspective view of an assembled state. This flush toilet water-saving device is a rubber float valve 32 that opens and closes the drain port 31 in the water tank 30 installed in the flush toilet, as described in FIGS. 7 and 10 showing the conventional flush toilet water-saving device. It is used by being attached in the vicinity of the connecting portion of the lifting rope 34 connected to the.

  As shown in FIG. 1, the water-saving toilet water-saving device includes a disk-shaped water-saving device main body 1 and an auxiliary member 2 that is coupled to the upper surface of the water-saving device main body 1 in an overlapping state. . In this embodiment, the water-saving device main body 1 is a mold casting made of zinc alloy chrome, and is formed with a predetermined weight, for example, a weight of 35 g to 45 g. The water-saving device main body 1 is formed in a substantially inverted U-shaped vertical cross-section, with a lid portion 3 continuously provided on the inner peripheral surface near the upper end opening of the ring portion 3 having a short cylindrical shape. A fitting recess 7 surrounded by the outer peripheral edge at the upper end of the ring portion 3 and the lid portion 3 is provided on the upper surface portion, and an inverted container-like space portion is provided below the fitting recess 7. 12 is provided. In the lid part 3, a cable passage opening 8 through which the pulling cable 34 (FIG. 7) passes is opened in the center, and a cable entry / exit slit 9 reaching the outer peripheral part from the cable passage opening 8 is formed in the cover part 4 and the ring. It is established in part 3. Further, three locking holes 10 are formed in the outer peripheral edge portion of the lid portion 4 at equal intervals (an angular interval of 120 °), and in the radial direction with respect to the rope passage opening 8 in the lid portion 4. Upward ribs 11 are formed at two locations facing each other on both sides.

  On the other hand, the auxiliary member 2 is an integrally molded product of synthetic resin, and the upper end portion of the circular frame portion 13 having an outer peripheral surface that fits into the fitting recess 7 of the water-saving device body 1 is covered with the lid portion 14. Has an external shape. In the central portion of the lid portion 14, a short tubular rope passage opening 17 having a planar shape from which a part of a circular shape that fits in the rope passage opening 8 of the water-saving device main body 1 is omitted projects downward. A cable entry / exit slit 19 that reaches the outer peripheral portion from a portion where the cable passage opening 17 is removed is formed in the lid portion 14 and the circular frame portion 13. The cord entry / exit slit 19 has a shape corresponding to the cord entry / exit slit 9 of the water-saving device main body 1.

  An elastic retaining piece 21 having a shape that complements the lacking portion is formed in the lacking portion of the rope passage opening 17 in an arrangement in which one end portion is connected to the rope passage opening. The tip of the elastic retaining piece 21 is a free end. Therefore, the elastic retaining piece 21 is provided so as to close the inner end of the wire entry / exit slit 19, and particularly elastically deformed when pressed in the direction toward the inside of the wire passage opening 17. Thus, the pulling line 34 is allowed to be introduced from the slit 19 into the line passing port 17, and the pulling line 34 is prevented from escaping from the line passing port 17 to the slit 19. A pair of bosses 18 that respectively fit into the pair of ribs 11 of the water-saving device main body 1 project from two locations facing each other on both sides in the radial direction on the lower surface of the lid portion 14. The circular frame portion 13 is formed with elastic locking claw portions 20 that are engaged with the three locking holes 10 of the water-saving device body 1 at equal intervals.

  The above-described flush toilet water-saving device is different from the one attached to the pulling rope 34 by assembling a plurality of parts like the conventional flush toilet water-saving device, as shown in the perspective view of FIG. 2 and the plan view of FIG. In addition, the holding member 2 is coupled to the water-saving device main body 1 so as to be attached to the pulling cable 34 in an integrated state. In other words, the water-saving device for flush toilets is put into the sales and distribution process in the form of an integral part as shown in FIGS.

  When the auxiliary member 2 is attached to and integrated with the water-saving device main body 1, the three elastic locking claws 20 of the auxiliary member 2 are inserted into the respective locking holes 10 of the water-saving device main body 1 as indicated by arrows in FIG. 1. Positioning so as to oppose each other, the circular frame portion 13 of the holding member 2 is fitted into the fitting recess 7 of the water-saving device main body 1 while pressing each elastic locking claw portion 20 into the corresponding locking hole 10. At this time, as shown in FIG. 4 which is a cross-sectional view taken along the line AA of FIG. 3, each elastic locking claw portion 20 has its guide taper surface 20a slidably in contact with the hole edge portion of the locking hole 10. When the guide taper surface 20a finishes passing through the locking hole 10 while being bent in the direction, the lower edge is the hole edge of the locking hole 10 due to the restoring force due to deformation. Engage with. As a result, the auxiliary member 2 is coupled to the water-saving device main body 1 in a retaining state by the engagement between the locking hole 10 and the elastic locking claw portion 20.

  The flush toilet water-saving device has only two parts, that is, the water-saving device main body 1 and the auxiliary member 2, and further, when assembling them, as described above, the three elastic locking claw portions Since it is only necessary to perform a one-touch operation to push 20 into the corresponding locking hole 10 of the water-saving device body 1 from above, the cost can be reduced with the reduction in the number of parts and the number of assembly steps.

  Further, as clearly shown in FIG. 2, the line entry / exit slit 9 of the water-saving device main body 1 and the line entry / exit slit 19 of the auxiliary member 2 are formed by the three elastic engagement claws 10 and the engagement holes 10. It is superposed | polymerized in the relative position which mutually corresponded by positioning. The both strip entry / exit slits 9 and 19 in the superposed state are closed by elastic retaining pieces 21 at the boundary with the passage passage port 17. As shown in FIG. 3, an elastic retaining piece 21 that is to be deformed outward is formed at the inner end of the slit wall surface of the auxiliary member 2 on the side of the slit 19 that does not support the elastic retaining piece 21. A deformation restraining step portion 22 is formed for preventing the elastic retaining piece 21 from deforming outward by abutting the tip of the elastic retaining member 21. Furthermore, since the water-saving device main body 1 is a cast product and the auxiliary member 2 is a molded product made of a synthetic resin, both of which are formed with high-precision dimensions, the auxiliary member 2 can be used as described above. 1, the ribs 11 of the water-saving device body 1 are automatically positioned on the pair of bosses 18 of the auxiliary member 2 as shown in FIG. Fit. Thereby, the auxiliary member 2 is prevented from rotating with respect to the water-saving device main body 1 and is integrated in a strong coupled state.

  Thus, when attaching the water saving tool for flush toilets in which the auxiliary member 2 is integrated with the water saving tool main body 1 to the lifting rope 34, the lifting rope 34 is connected to the pair of ropes in a superposed state from the outer periphery of the water saving tool. When the pulling line 34 is inserted into the entrance / exit slits 9 and 19 and the pulling line 34 comes into contact with the elastic retaining piece 21, the pulling line 34 is pressed in the direction in which the pulling line 34 is pulled into the line passing port 17. The retaining piece 21 is elastically deformed so as to be bent inward by being pushed inward by the pulling line 34, and the pulling line 34 enters the line passing port 17. The deformed elastic retaining piece 21 returns to its original shape by its own restoring force and closes both the cord entry / exit slits 9 and 19, so that the lifting cord 34 is prevented from coming off from the filament passage opening 17. The Thus, this flush toilet water saving tool is different from the conventional flush toilet water saving tool that is attached to the pulling rope 32 by assembling a plurality of parts, so that the single flush toilet water saver can be touched with one touch. It can be easily attached to the lifting cable 34 by operation.

  As shown in FIG. 6, the water-saving toilet water-saving device attached to the lifting line 34 is placed on the rubber float valve 32. At this time, a part of the rubber float valve 32 is attached to the water-saving device main body 1. Even though the lower peripheral surface of the ring portion 3 is the surface of the spherical surface of the rubber float valve 32, it is placed and held in a stable state on the surface in the arrangement that has entered the space portion 12. Further, as shown in FIG. 2, the water-saving device main body 1 and the auxiliary member 2 are accommodated in such a manner that the circular frame 13 is completely fitted in the fitting recess 7, and the three elastic locking claws 20. And the locking hole 10 are prevented from coming off, and the pair of ribs 11 and the boss 18 are prevented from being rotated and integrated with each other, so that the pulling rope 32 is pulled and the water tank 30 associated therewith is pulled. (FIG. 9) There is no possibility of causing rattling due to the water flow in the inside.

  Further, in the water-saving toilet flushing device, the weight for setting the rubber float valve 32 to close the drain port 31 is set mainly by the metal water-saving device main body 1, while the auxiliary member 2 is made of synthetic resin. Since it is an integrally molded product, it is possible to suitably form the elastic retaining piece 21 and the elastic locking claw portion 20 that are required to have the required elastic force, and to have a highly accurate dimension. The water-saving device main body 1 can be coupled in a state of being fitted without rattling.

  In the example shown in FIGS. 7 and 8, the auxiliary member 2 omits the elastic retaining piece 21 as in the previous example, and instead of the elastic retaining piece 21, the rope passage opening 17 and the rope are provided. The entrance / exit slit 19 is smaller than the opening diameter of the ridge passage opening 8 and the opening width of the ridge entry / exit slit 9 of the water-saving device main body 1, and has a constricted portion 34a such as a ball chain illustrated in FIG. Then, the narrowed portion 34a has a constriction width 34a in the longitudinally extending strip 34, for example, an opening edge 17a, 19a having a thickness T that is substantially equal to or less than the constriction width B of the intermediate constricted portion. Other than that, there is no particular difference from the case of the previous example, so common members and parts are denoted by the same reference numerals, and overlapping illustrations and descriptions are omitted.

  According to this, instead of the elastic retaining piece 21 of the previous example, the ridge passage opening 17 in the auxiliary member 2 and the opening edges 17a and 19a of the ridge entry / exit slit 19 are formed in the ridge passage opening in the water-saving device main body 1. 8 having an opening diameter of 8 and a width T smaller than the opening width of the entry / exit slit 9 and having a constricted portion 34a repeatedly and being substantially equal to or less than the constriction width B of the continuous strand 34 in the longitudinal direction. , While making it easy to enter and exit the cable passage opening 17a through the cable entry / exit slit 19a at the constricted portion 34a of the cable 34, the cable 34 at the cable passage 17 and the cable entry / exit slit 19 with respect to the cable 34 The play in the direction perpendicular to the longitudinal direction is suppressed, and the movement of the auxiliary member 2 with respect to the longitudinal direction of the ridge 34 makes the dimension of the constricted portion of the ridge 34, particularly the dimension D larger than the minimum constricted portion dimension D1. Suppression with the non-constricted portion 34b having (FIG. 7) can be realized to a necessary degree by selecting the dimensions of the opening diameter D3 and the opening width B1 (FIG. 8), and the rubber float valve 32 can be opened and closed. Also, the water-saving device is settled against the rope 34 and the rubber float valve 32 by the flow of water during supply and drainage, so that the water-saving action can be exhibited more stably and no abnormal noise is generated.

  The auxiliary member 2 has concave portions 17b and 19b having a size corresponding to the rope passage 8 and the slit 9 of the water-saving device body 1, and the opening edges 17a and 19a extend inside the concave portions 17b and 19b. It is supposed to be provided. Thus, the opening edges 17a and 19a are provided so as to extend inside the recesses 17b and 19b having a size corresponding to the rope passage 8 and the slit 9 of the water-saving device main body 1 in the auxiliary member 2. And, securing the coupling strength with the water-saving device main body 1 at the portion other than the opening edges 17a, 19a, and without impairing the ease of entering and exiting the cable passage opening 17 through the slit 19 of the cable 34, Play between the rope 34 and the water-saving device can be suppressed.

  In the example shown in FIGS. 7 and 8, both the opening diameter D3 of the cable passage opening 17 and the opening width B1 of the cable entry / exit slit 19 are smaller than the size D2 of the non-constricted portion 34b of the cable 34. The constricted portion 34a is larger than the size D1, and the water-saving device is the longitudinal portion of the rope 34 with respect to the rope 34 at the rope passage opening 17 and the stripe entry / exit slit 19 portions, particularly at the rope passage passage portion 17 parts. It makes it easy to restrict movement in the direction. However, the slit 19 enters and exits from the middle while securing a sufficient open width B1 that allows the constricted portion 34a of the rope 34 to enter and exit the rope passage opening 17 with a sufficient margin. A restriction width portion B2 is provided at the opening portion to the mouth 17 to restrict the entry and exit of the rope 34, and the rope 34 is inadvertently slipped from the rope passage opening 17 to the rope entry and exit slit 19, Further, it is possible to prevent the cable 19 from going out from the entry / exit slit 19. In particular, the opening portion to the ridge passage opening 17 is the narrowest portion in which the degree of squeezing is less than the indented portion dimension D1 of the ridge 34, and after the ridge 34 is once inserted into the ridge passage opening 17, the ridge slit 19 It is possible to prevent the accidental withdrawal sufficiently. It is also possible to facilitate the introduction of the cable 34 by setting the opening width of the cable entry / exit slit 19 to the outer periphery of the auxiliary member to be larger.

  Note that the thickness of the opening edges 17a and 19a may be as thin as about 0.3 mm, and a normal resin member that is not a rubber material even if there is a portion smaller than the opening width B1 smaller than the constriction portion dimension D1 as described above. Also, elastic deformation that can easily move the ridge 34 is obtained. However, the opening edges 17a and 19a can be formed by another member such as a rubber sheet sandwiched between the water-saving device main body 1 and the auxiliary member 2. In some cases, the notches 17b as shown in FIG. By forming one or more on the inner periphery of the passage opening 17, the opening edge 17 a is not constricted with respect to the line 34 located at the line passage opening 17 in cooperation with the cutting state by the line entry / exit slit 19. It is also possible to make it easier to adjust the position elastically over the portion 34b.

  Furthermore, the auxiliary member 2 has recesses 17c and 19c having a size corresponding to the cable passage opening 8 and the cable entry / exit slit 9 of the water-saving device main body 1. Opening edges 17a and 19a are provided inside the recesses 17c and 19c. It is provided to extend. As a result, the coupling strength with the water-saving device main body 1 is ensured at portions other than the opening edges 17a and 19a, and in addition, the ease of entering and exiting the cable passage opening 17 through the cable entry / exit slit 19 of the cable 34 is improved. The play between the rope 34 and the water-saving device can be suppressed without damage.

  By installing this water-saving device for flush toilets on the lifting line in the water tank installed in the flush tray, the timing of closing the boom float valve can be advanced by its own weight, so the amount of water used in the flush toilet About 20% can be saved, and wasteful use of tap water can be eliminated.
