Description

Description
MIXER TAP WATER SAVERS
TECHNICAL FIELD [0001] The invention relates to a water mixing faucet able to provide its user with heat-treated water such as hot water without wasting the water of the water pipe. hot water that has cooled down and must be evacuated to obtain hot water. The invention also relates to a water mixing valve for hot countries, able to provide its user with chilled water without wasting the water of the refrigerated water pipe that has warmed and must be evacuated to obtain effectively chilled water.
The invention also relates to a running water system comprising a water saving mixer tap.
Prior Art [0003] In a running water system comprising hot water pipes, the hot water source (water heater, hot water tank, etc.) may be at a considerable distance from the consumption points . When all consumption points are closed, the water in these hot water pipes cools naturally. For this reason, when there is then a new demand for hot water, it is normally necessary to let the water initially contained in these pipes to be able to reach the desired water temperature at the point of consumption. This is an important source of water wastage.
Patent document WO 2011/009915 A1 discloses a water saving mixing valve and a running water network arrangement where the cold water contained in the hot water pipe can be pushed back to a tank via the cold water line which is maintained at a lower pressure than the hot water line. The mixing valve comprises a position of interconnection of the hot water inlet with the arrival of cold water.
Patent document CA 2 252 350 A1 also addresses the problem of wasting water when the source of heat or hot water is remote from the draw-off point of the distribution network. To do this, this teaching provides for a hot water storage tank cooled and two valves. One of the two valves controls the water supply from the hot water line and the other controls the cold water supply from the tank outlet. A thermostatic device is disposed downstream of the first valve and an auxiliary pipe is connected to the hot water pipe, between the first valve and the thermostatic device, and to the tank. When the first valve is open, the water of the hot water line that has cooled in the meantime is prevented from flowing to the outlet point by the thermostatic device and thus flows via the auxiliary line to the reservoir . When the water temperature reaches a limit value, the thermostatic device opens and the hot water can then flow to the outlet point. The initially hot and cooled water that has been diverted to the tank can be consumed as cold water via the second valve. This teaching also discloses a second embodiment of distribution network with a mixing valve. The latter comprises a connecting pipe to the auxiliary pipe, the connecting pipe comprising a valve device cooperating with a thermostatic device disposed in the auxiliary pipe. This device is interesting in its general principle and its goal to achieve. However, it requires the implementation of a number of components and connections via pipes, which makes the solution difficult to apply from a commercial point of view. Summary of the invention

DESCRIPTION OF THE EMBODIMENTS [0050] FIG. 1 shows an example of a connection diagram of the quick-acting water-saving mixer tap according to a first embodiment of the invention. This connection diagram is preferably for a new sanitary installation or when the installation of an additional pipe for chilled water is possible or already existing. A source of cold water such as a connection to the mains water distribution network 6 preferably passes via a non-return valve 8, to form the cold water inlet 10 which is directly connected to a first orifice or first inlet 32 of the mixing valve 4. The cold water inlet 10 is connected, preferably also via a non-return valve 12, to a water heating device 20. The hot water inlet 22 from the water heating device 20 is connected to a second or second inlet 36 of the mixing valve 4. The mixing valve 4 comprises an auxiliary outlet 34 connected via an auxiliary pipe 24 to the suction port of an automatic pump 18. The The output of the automatic pump 18 is connected to the inlet of the water heater 20. An expansion vessel 14 can be mounted on the inlet pipe of the water heater 20 to compensate for changes in the temperature. volume of the e during his warm-up. An expansion vessel 16 is also preferably connected to the auxiliary line 24 to optimize the size of the automatic pump 18.
[0051] Figure 2 illustrates in more detail the valve 4 of Figure 1. It is in a neutral position called service flow closure and without connection of hot and cold water arrivals. It comprises a fixed disk 42 with four orifices not visible in FIG. 2. These orifices are connected to the cold water inlet 32 and the hot water inlet 36, to the auxiliary water outlet 34 and to the water outlet of FIG. service 38. These openings are visible in Figures 3 to 6 and will be detailed in connection with the description of these figures. The mobile disk 44 is able to move in translation and in rotation on the fixed disk 42, and in a sealed manner. Its movement is controlled by the control lever 40 via a mechanism visible in Figure 2. The movable disk 44 comprises a support 48 sealingly mounted on the disk. This support contains thermostatic means capable of controlling the displacement of the mobile disc 44. The latter comprises a first cavity 50 formed by a through-orifice shown in more detail in FIGS. 3 to 6 and allowing a direct passage of the hot water towards the auxiliary pipe 24 while maintaining contact with the thermostatic element in the corresponding cavity of the support 48. The direct passage of hot water to the auxiliary pipe 24 provided by the cavity 50 reduces the time required for the preparation of hot water to an extent that the user will have hot water faster by operating the hot water preparation mode than by letting the water flow into the sink which is an additional advantage and an incentive to use preferentially the function of hot water preparation that saves water.
The compression spring mounted between the thermostatic element and the pusher in the support 48 is capable alone to push the movable disc 44, its support 48 and the control lever 40 to the closed position of the mixer which is illustrated in Figure 2. The pusher is limited in its movement by a stop which slides in a groove of the support 48 of the movable disc 44. The locking and unlocking of the pusher in the support 48 of the movable disc results from the radial position of one or more balls that slide freely in the radial holes of the pusher and which bear on the outer profile of a piston which slides freely in the pusher.
In the closed position of the mixer that corresponds to Figure 2, the pusher is pushed to the right under the effect of the spring until the stop comes into contact with the support 48 of the movable disk 44. The balls are slid into the pusher. By pushing the lever 40 downwards, the support 48 of the mobile disk is moved to the right and the push rod is forced to enter the support 48. The cold thermostatic element allows the piston to move to the left under the effect of the return spring, which causes the outward movement of the balls, in the groove of the support and therefore the locking of the pusher in the support. When hot water comes into contact with the thermostatic element, the expansion of its internal component pushes the rod and the piston to the right against the effect of the return spring. The displacement to the right of the piston allows the balls to slide inwardly of the pusher, which causes the release of the pusher which pushes under the effect of the spring support 48 to the left in the closed position of the mixer which corresponds to Figure 2. The piston arranged vertically in the valve body, under the effect of its spring, causes a slight snap to mark the different positions of the control. The displacement control device of the mobile disk which has just been described is further detailed in the international patent application No. PCT / EP2012 / 050850 filed on January 20, 2012, in particular in relation to FIGS. 10 to 13 and their description. The content of this application, more particularly the figures and / or passages mentioned above, is incorporated by reference.
Figure 3 shows the detail of the fixed distribution disk 42 and the mobile distribution disk 44. The faces in contact achieve the tightness of the mixer. The fixed distribution disc 42 is provided with four through holes. The first orifice 56 is connected to the cold water inlet materialized by the circle in broken line 32 corresponding to the passage in the body of the mixing valve. The second orifice 58 is connected to the hot water inlet materialized by the dashed circle 36 corresponding to the passage in the body of the mixing valve. The third orifice 60 is connected to the auxiliary water outlet materialized by the circle in broken line 34 corresponding to the passage in the body of the mixing valve. The fourth port 54 is connected to the service water outlet 38 of the mixing valve.
The third orifice 60 is intended to evacuate the cold water initially contained in the hot water pipe 22 (Figure 1) and the warm water of the pipe preceding the arrival of hot water.
The mobile disk 44 comprises the first cavity 50 in the form of a through orifice communicating with a chamber of the support 48 (Figure 2) comprising the thermostatic control means. The first cavity 50 is intended to put in communication the hot water inlet 58 and the auxiliary water outlet 60 when the control lever is turned to the left and pushed down to activate the hot water preparation function. . When the water flowing through the first cavity 50, in contact with the thermostatic control means described above, sees its temperature increase gradually, said thermostatic means react from a certain temperature by moving the mobile disk 44 back to a closed position without interconnection of the hot water inlet 58 with the auxiliary water outlet 60.
The movable distribution disc 44 has a second cavity 52 intended to put in communication the first cold water inlet port 56 and / or the second hot water inlet port 58 with the outlet orifice serving water 54 of the fixed disc 42 when the lever 40 is raised to the service position.
Figure 4 shows a top view of the two distribution discs in the closed position, horizontal control lever in the central position. None of the orifices of the fixed disk is in communication with one of the other orifices of said disk.
Figure 5 shows a top view of the two dispensing discs when the lever of the mixer is turned completely to the left and pushed down in the position corresponding to the function of hot water preparation. The hot water inlet 58 is brought into communication with the auxiliary water outlet 60 through the first cavity 50 and contacts the thermostatic element in the support 48 (FIG. 2) of the disk. mobile 44.
FIG. 6 shows a view from above of the two distribution disks when the control lever is raised in a central interconnection position by the second cavity 52 of the first, second and fourth orifices 56, 58 and 52, respectively, for a discharge of a mixture of hot and cold water to the outlet.
Control means of the pump 18 may be provided to regularly transfer the water from the auxiliary pipe 24 to the hot water pipe 22. More particularly, the transfer of water can take place from the vessel expansion 16 to the hot water pipe 22, and more particularly to the expansion vessel 14.
FIG. 7 shows an example of a connection diagram of the quick-acting water-saving mixer tap according to a second embodiment of the invention. The reference signs of the first embodiment are used in the second embodiment for the same elements or corresponding elements, these signs being however increased by 100 for the sake of clarity and distinction of the embodiments. Specific reference signs are used for elements not present in the first embodiment, these signs being between 100 and 199.
This second embodiment is intended for an existing sanitary installation in which it is difficult or expensive to add an auxiliary line return cooled water to the inlet of the water heater. A source of cold water such as a connection to the mains water distribution network 106 preferably passes through a check valve 108, to form the cold water inlet 110 which is directly connected to a first orifice or first inlet 132 The cold water inlet 110 is connected, preferably also via a non-return valve 112, to a water heating device 120. The hot water inlet 122 from the heating device water 120 is connected to a second or second inlet 136 of the mixer 104. Similarly to the first embodiment of the invention, the mixer 104 comprises an auxiliary outlet 134 connected via an auxiliary line 124. However, unlike the first mode of realization, the auxiliary pipe does not include a water transfer pump. It comprises an expansion vessel 116 capable of accumulating the cooled hot water during the preparation of hot water. In practice, the auxiliary pipe 124 can be very short and the expansion tank 116 can be located at the most convenient place, for example below the sink receiving the mixer 104.
Figure 8 shows the detail of the fixed distribution disc 142 and the movable distribution disc 144. The faces in contact achieve the tightness of the mixer. The fixed distribution disk 142 is identical to that of the first embodiment (see for example Figure 3). The mobile distribution disk 144 also has two cavities 150 and 152 as the mobile disk of the first embodiment (see for example Figure 3). The second cavity 152, however, comprises an extension 162 which allows evacuation of the water from the auxiliary pipe 124, more particularly the expansion vessel 116, to the service water outlet 138 when the lever of the mixer is in a raised central position corresponding to the opening of the mixer for a mixture of hot and cold water.
Figure 9 shows a top view of the two distribution discs 142, 144 in the closed position, horizontal control lever in the central position. None of the orifices of the fixed disk is in communication with one another.
[0066] Figure 10 shows a top view of the two distribution disks when the control lever of the mixer is oriented completely to the left and pushed down in the position corresponding to the hot water preparation function. The hot water inlet port 158 is brought into communication with the auxiliary water outlet port 160 and contacts the thermostatic element via the passage in the support of the mobile disk 144.
Figure 11 shows a top view of the two distribution disks when the control lever is raised in a central flow position of a mixture of hot water and cold water to the service outlet. The extension or protrusion 162 of the cavity 152 is in communication with the rest of said cavity to allow the evacuation of the water contained in the expansion vessel 116 of the auxiliary pipe 124. In this position, the orifice of The service water outlet 154 is in communication with the hot water inlet port 158, with the cold water inlet port 156 and the auxiliary outlet port 160.
[0068] Figure 12 is a top view of the two distribution disks when the control lever is raised to a fully left position for a flow exclusively hot water to the service outlet. It can be seen that the contour of the third port 160 is configured to allow the second cavity 152 of the movable disk 144 to connect the second port 158 exclusively with the fourth port 154. The second cavity has a generally rounded and circular contour, and the contour of the third orifice 160 has a portion directed towards the center of the disc, which is inclined so as to bypass the corresponding portion of the profile of the second cavity.
Figure 13 is a top view of the two distribution disks when the control lever is raised to a fully right position for a flow exclusively cold water to the service outlet. It can be seen that the protuberance 162 of the second cavity 152 of the movable disk 144 is configured to extend between the second and third ports 158 and 160 respectively. The latter are spaced from each other and the two disks are configured so that the outgrowth covers neither the second nor the third orifice in the position of cold water flow exclusion.
Figure 14 is an example of a connection diagram of the fast-acting water-saving mixer tap according to a third embodiment of the invention. The connection circuit is the same as that of the first embodiment, the fast-acting water-saving mixing valve is however of the thermostatic type. The thermostatic mixing valve is shown with the control lever lowered in the hot water preparation mode.
The reference signs of the first embodiment are used in the third embodiment for the same elements or corresponding elements, these signs being however increased by 200 for the sake of clarity and distinction of the embodiments. Specific reference signs are used for the elements not present or different in the first embodiment, these signs being between 200 and 299.
Figure 15 shows the detail of the fixed distribution disc 242 and the movable distribution disc 244. The faces in contact perform the sealing of the mixer. The fixed distribution disc 242 has four through holes.
