Description

Improvements in a device to control the water discharge valve of a cistern for appliance sanitary.

The present invention relates to improvements in a device for controlling the water discharge valve of a cistern for sanitary equipment. In particular, the invention is refers to improvements in a control device that allows the total emptying or partial emptying of the tank.

In valve control devices discharge, it is usually necessary to control the closing of the valve such that it allows the total emptying of the tank. In these devices, the closing of the valve slows down by several devices that use vacuum aspiration.

By EP-A-0801179 a control device is known in which the discharge tube outlet carries an annular element to close the valve discharge, which allows output discharge through the tube and annular element In addition, the discharge tube acts as a float cancel, and rises by operating a first button button to control the partial drainage of water from the tank. A second concentric float with the discharge tube, and that it has a hydrostatic thrust greater than the weight of the discharge tube, it is usually prevented from climbing on a hook in the second float. This is released by operating a second button push button to slow the valve closure until the level of water falls below the second float, so that the cistern is completely empty.

The operation of this hook is carried out by a separate kinematic mechanism, which means that the device Control is relatively complicated and expensive. In addition, in the case of total emptying, the associated kinematic mechanism must also simultaneously lift the discharge tube, which requires a greater strength Finally, the known device requires the perfect alignment of the push button connection with the valve Download

The object of the invention is to provide a control device for the discharge valve of a cistern for such a sanitary device, which is simpler and more reliable to operate, and that has reduced manufacturing costs.

According to the invention, this object is achieved by the control device for the water discharge valve of a cistern for sanitary equipment, which includes a closing element Valve supported on a first float, a control element operable with a predetermined run to raise said first float, and a second substantially concentric float with said first float and with a hydrostatic thrust greater than the weight of said first float, usually preventing said second float rises so that it does not affect the return to below said first float to control the partial emptying of said cistern, and being released to slow the return to resting of said first float, thus controlling the total emptying of  said cistern, and is characterized in that a fixed hook normally said second float and can operate by said element by a extra run beyond that predetermined run to release said second float.

According to another aspect of the invention, for compensate for a situation where a hole in the bottom wall of the cistern and a hole at the top of the cistern are off-center, the control element is connected to a first sleeve mounted on a cup-shaped connector fixed on the hole in the upper part, while said valve is fixed to the bottom of the cistern, said element acting by said first sleeve in a concentric flange with said hole on the bottom.

For a better understanding of the invention, here a preferred embodiment described by way of example is described with reference to the attached drawings, in which:

Figure 1 is a partial sectional view of a device for controlling the emptying of water from a cistern, according to the invention.

Figure 2 is a perspective view exploded from some parts of the device of figure 1.

Figure 4 is a middle section view of enlarged scale of a portion of figure 1.

Figure 5 is a perspective view of a detail of figure 1.

Figure 6 is an exploded sectional view of some parts of figure 4.

And figure 7 is a perspective view exploded from a detail of figure 6.

With reference to figure 1, the number of reference 5 indicates a water cistern for sanitary equipment, provided with the usual valve for connection to the pipes water supply, and the usual float to control this valve, not indicated in the drawings. Tank 5 also has a base wall 6 with a hole 7 in which a device is mounted to control the discharge of water, indicated in general 8. A discharge connector 9 includes a threaded bottom portion 11 inserted in hole 7 with an interposed seal 12, and fixed by a threaded nut 13. A portion 14 of the connector 9 It has holes 16 to allow water to pass through it. A bracket 19, fitted in bayonet on discharge connector 9, includes an outer wall 21 and an inner wall 22 that defines a annular space 23. The outer wall 21 has a hole 24 for allow slower emptying of space 23. This space 23 is closed at the top by a recerrable lid 26, which delimits inside by an annular edge 27 that has a larger diameter than that of the inner wall 22. The lid 26 has a pair of holes 28, of which only one can be seen in Figure 2, whose through water enters space 23.

The usual outlet discharge tube 29 is guided slidingly inside the wall 22, tube carrying a ring 31 (figure 1) made of elastic material, which rests on a boss 32 of connector 9. Boss 32 thus defines the seat for the discharge valve of the tank 5, which is closed by the ring 31. The tube 29 also carries a disc 33 that allows it function as a first float to control the return of the ring 31 to the closed position of the discharge valve. Disk 33 is low against the action of a spring, not visible in figure 1, when the water column in tube 29 exceeds a certain level expected maximum H for tank 5, as described in the Italian Patent Application number TO96A000276 in the name thereof Applicant.

The discharge tube 29 also has in its part upper an outer radial fin 34 having a vertical groove 36 in which it engages a pin 37 supported on a vertical plate 38. This has a horizontal tab to which 39 a connecting rod, able to move up to raise tube 29, as will be best seen below.

A second float is accommodated in space 23 of bracket 19, float that is formed from a housing 41 which is open at its base. The upper part of the inner wall of the housing 41 enters a sleeve 42 guided between the wall 22 of the support 19 and the inner ring 27 of the cover 26. The sleeve 42 it has an axial nerve 43 that engages in a radial recess 44 (see also figure 2) in the ring 27 to prevent rotation of the second float 21 around the discharge tube 29. The float 41, when submerged in water, it has a hydrostatic thrust greater than the weight of tube 29. Tube 29 has two protrusions radial 47 (see also figure 3) hooked by the edge upper cuff 42.

The cover 26 is fixed to a pair of pillars diametrically opposed verticals 48 (figure 2), each having an inner wall 49 and two tabs 51. At the bottom, the tabs 51 of a pillar 48 are connected to tab 51 of the another pillar 48 by means of a pair of edges 52 and 53. The edge 52 it has two portions 54 substantially parallel to tab 51 of the pillars 48, two portions 56 perpendicular to the portions 54, and a portion 57 to connect the two portions 56.

Between the two portions 56 a pin 58 (figure 1) in which a hook 59 is pivoted, which is can move in a radial plane with respect to tube 29 and hooks the edge of the sleeve 42 to prevent upward movement of the second float 41. The hook 59 has a fork 61 which hooks a bar 62 supported by a lever, indicated in general 63 (see also figure 5).

In particular, lever 63 is formed from two symmetric arched portions 64, pivoted each in a corresponding pin 66 (see also figure 2) attached to the corresponding pillar 48. The two portions 64 thus surround the tube discharge 29 and float 41. Lever 63 is also operable by the connecting rod 39 by means of a slide 66. To do this, lever 63 is provided with a pin 67 diametrically in front of the bar 62 and engaging a groove 68 in the sliding 66.

Slider 66 also has a second slot. vertical 69 in which another pin 71 is attached, fixed to a fin vertical of the plate 38 of the connecting rod 39. At its base, slot 69 has an extension 72 to allow it through pass a T-shaped head of spike 71. The dipstick connection 39 has a series of channels 73 (figures 1 and 3) arranged  by default A C-shaped connector element 74 It has a pair of 76 internal protrusions that engage by spring in one of the channels 73 of the connecting rod 39. In addition, the element 74 has two diametrically opposite spikes 77 in which hook two parallel protrusions in the form of hook 78, fixed to a return lever 79.

The control device also includes a cup-shaped connector 81 (figures 4 and 6) to support a control element for partial emptying and total emptying of the cistern water 5, formed from a push rod 82. Connector 81 has a hollow pin threaded on the outside 83. The connector 81 also has a flange 84 that hooks a ring of joint cover 86. Pin 83 is inserted into a hole 87 in the usual cover 88 of the tank 5. The hole 87 can be deviated, within certain limits, with respect to hole 7 (figure 1) on the base wall 6.

The pin 83 engages a threaded portion 89 (figure 2) of a sleeve 91. This has two pairs of plates of Guide 92 cooperating with two prismatic guides 93, supported by a box-shaped portion 94 of a support, generally indicated 96. Sleeve 91 also has two radial projections diametrically opposed 97, each of which hooks a slot 98 in the respective prismatic guide 93. In addition, the sleeve 91 has two radial projections 99, located at 90 ° with respect to the protrusions 97, and that hook two grooves 100 on two wings diametrically opposed 101 fixed to another sleeve 102 which has a threaded inner portion 103 (see also Figure 6).

Sleeve 102 has four axial ribs 104 by means of which it remains centered on the sleeve 91. The push rod 82 has a threaded portion 108 engaged with the threaded portion 103 of the sleeve 102, and has a projection upper cruciform 109. Push rod 82 also has a axial channel 111 engaging a radial projection 112 at the edge bottom of pin 83 to prevent it from rotating.

The support 96 has a hollow cylindrical body 114 (figure 2) with a pair of annular nerves that delimit a arched channel 116, and an upper flange 117 for connection with the box 94. The hollow body 114 is rotatably housed in a ring 119 supported by another support 118 connected to the cover 26, as You will see better below. Tab 117 rests on the edge of the ring 119, whose outer surface has two axial ribs 121 that stand out above hoop 119 to cooperate with a couple of projections 123 of tab 117 so as to limit the rotation of support 96 in ring 119.

The holder 118 also has a horizontal plate 124 provided with a central hole 126. Plate 124 has a integral sleeve 127 (figure 4) whose inner surface is tapered slightly to accommodate a hollow tang 128 of a flange 129. This is capable of moving vertically inside the hollow body 114 and be hooked by the bottom surface of the sleeve 102. The plate 124 is connected to ring 119 by means of two segments diametrically opposed 131 (figure 2) interspersed with two walls flat 132 on the tangent to the ring 119. Each wall 132 is connected to the associated nerve 121, and includes a curved portion to form a tangential guide 133.

The two guides 133 are parallel and speculative, and they have a semicircular section similar to that of channel 116. A Element 134 for quick connection of brackets 96 and 118 has two parallel arms 136 inserted in the two guides 133 and the channel 116 of the hollow body 114, allowing the support 96 to be orient angularly with respect to support 118. Element 134 it also has a transverse element 137 to connect the two arms 136, which is manually operable to move element 134, substantially as described in the Model Request for TO96U000075 utility.

Plate 124 of support 118 is also provided with two parallel vertical tabs 138 (figures 3 and 4) which have two holes in which a rotationally housed pin 139 of the return lever 79. The lever has one arm 141 hooked by pin 128 of tab 129. In turn, the support 118 has two diametrically opposed serrated bars 142 connected to plate 124 and ribs 121. Bars 142 are extend down and engage between the two tabs 51 of the pillars 48. Bars 142 have a series of teeth 143 which they have the same separation as the channels 73 of the rod connection 39.

The two tabs 51 of each pillar 48 have two corresponding slots 144 (figure 2) aligned with each other and of dimensions corresponding to the section of a space between two adjacent teeth 143 of the bars 142. Two screws 146 of a second quick connect element 147 are introduced in both slots 144. This includes a cross piece 148 to connect the screws 146, which is manually operable to connect the support 118 with the cylindrical support 19, as described in the Utility Model Application mentioned above.

The cup-shaped connector 81 (figures 6 and 7) houses a pair of pushbuttons 151, 152 that have a shape Complementary to fully occupy the interior area of the connector 81. The two push buttons 151 and 152 are formed from two curved sheets that snap on two tabs corresponding 153 and 154, and have 156 ribs of shapes different to identify the installation by touch. Both tabs 153 and 154 are fixed to two axial hollow spikes corresponding 157 and 158.

Pin 83 of connector 81 has a pair of elements, each formed from an edge 159 that protrudes to each of two elastic portions 161 and 162 of pin 83. Portions 161 and 162 are located diametrically in front of the end of pin 83 adjacent to connector 81, and each is delimited by a C-shaped groove 163 of pin 83. The elastic portions 161, 162 elastically engage the two hollow pins 157, 158 so as to allow axial movement, while preventing them from leaving connector 81.

In particular, push button 151 is adapted to operate the push rod 82 in one run default, which controls the partial emptying of the tank 5. Pin 157 of associated tab 153 has a discharge 164 in which hooks an elastic protrusion in the form of hook 166 of a pin 167, which engages the protrusion 109 of the push rod 82. Pin 167 has a protrusion 168 at its base and engages elastically below the edge 159 of the elastic portion 161. Tab 153 has a tongue 170 that defines the stroke of the push button 151.

Push button 152 moves the push rod 82 in a stroke greater than that controlled by button 151, to check the total drain of the tank 5. Pin 158 of the tank associated tab 154 is located outside pin 157 and has a protrusion 169 elastically engaging below edge 159 of the elastic portion 162. The pin 158 has a notched portion 171 to allow the difference in the stroke of the two buttons 151, 152, and a notched portion 172 to allow operation of the push button 151 without affecting push button 152.

The control device 8 is mounted on the premises of the client as follows.

First of all, connector 81 is unscrewed from the sleeve 91 (figure 4) so that the push rod 82 is unscrew the sleeve 102 and can be removed together with the connector 81, the two pins 157 and 158 and the two push buttons 151, 152. Portion 11 of connector 9 is then inserted into the hole 7 on the base wall 6, and fixed with the ring 37 with the seal 12 interposed in between. In addition, if necessary, the tube height 29 can be adjusted by cutting the excess part.

Then, removing the connection element 147 (Figure 2), the distance between support 118 and cover 26 is regulates according to tank dimensions 5. Bars 142 are now fix back to the pillars 48 by means of the element of connection 147. Now, the connection of the connecting rod 39 (Figures 1 and 3) with lever 79 is regulated by entering the projections 76 of the C-shaped element 74 in a channel 73 of the connecting rod 39 corresponding to the position of the bars 142. The resting position of arm 141 of lever 79 is a high position, and the arm holds the tab 129 in the high position of figure 4.

Then connector 81 is fitted (figure 4), together with the push rod 82 and the push buttons 151, 152, in the hole 87 in the lid 88, with the possible interposition of the ring joint coverage 86. In fact, the purpose of ring 86 is primarily aesthetic, and is used when the hole diameter 87 is lower than that of connector 81. On the other hand, ring 86 is always omit that the diameter of hole 87 is such that it can accommodate connector 81. In this case, tab 84 of connector 81 rest directly on lid 88.

The support 96 is now oriented with respect to the support 118, and the two sleeves 91 and 102 move radially, compensating for possible misalignment of hole 87 in cover 88 with respect to the hole 7 in the base wall 6 of the tank 5. Then, placing the lid 88 on its seat in cistern 5, it screw the pin 83 of the connector 81 into the threaded portion 89 of the sleeve 91, and the threaded portion 108 of the push rod 82 is screw into the threaded portion 103 of the sleeve 102. The stem of push 82 thus axially moves the sleeve 102 by putting it substantially in contact with flange 129 (figure 4).

The control device 8 for the valve Tank 5 discharge operates as follows.

At rest, cistern 5 (figure 1) is full of water at level H defined by the usual float to close the water supply valve. The outlet discharge tube 29 is in the low position of figure 1, in which the ring 31 rests against the projection 32, so that the discharge valve is closing. Water in space 23 pushes float 41 up, but it is held by hook 59.

When push button 151 is pressed (figures 4 and 6), the associated pin 157 acts, by means of pin 167, in the push rod 82, and makes the grooves 100 in the wings 101 slide on projections 99, moving sleeve 102 down. The sleeve 102 acts on the flange 129 so that the pin 128 act on arm 141, causing return lever 79 to rotate in the left direction a corresponding amount. The lever 79, using connecting rod 39 (figure 1), goes up then the discharge tube 29, removing the ring 31 from the projection 32 to open the discharge valve.

In turn, the pin 71 moves the slide 66 (figure 5) up, whose groove 68 slides in pin 67 of lever 63. Connecting rod 39 allows movement lost with respect to the slide 66, so that the lever 63 do not turn and hook 59 (figure 1) remains in the position where  hold the edge of the sleeve 42 of the float 41. The water starts now to flow through connector 9, creating a push hydrostatic in the float including disc 33 and tube 29, of so that it stays in a high position. When the level of water in cistern 5 falls below an intermediate level h, where the hydrostatic thrust on the float 29, 33 is equal to the weight of this float, the tube 29 descends by gravity, closing the discharge valve

Moreover, pressing the push button 152 (Figures 4 and 6) makes it run longer than the push button stroke 151, and acts with its pin 158 in the push rod 82. This, by means of sleeve 102, the flange 129, pin 128 and lever 79, move the connecting rod 39 (figure 1) up one run higher than in the previous case, so that the connecting rod 37 performs an extra stroke. The pin 37 moves the discharge tube 29 upwards, opening the discharge valve, substantially as described above, so that the tube 29 is pushed up by the hydrostatic thrust.

But now, spike 71, after having made its lost movement with respect to the slide 66 (see also figure 5), now turn lever 63 in the direction toward the left. Bar 62 now rotates hook 59, releasing the edge of the sleeve 42. The float 41, by virtue of the thrust hydrostatic, it now moves up until it hooks the projections 47 of tube 29 with its upper edge. The push hydrostatic acting on float 41 now leads to the latter to rest against the lid 26, and the discharge tube 29 is raise.

The now water comes out of the discharge, but when the hydrostatic thrust in tube 29 is equal to its weight, tube 29 it is still maintained by float 41. Since hole 24 allows a slow emptying of space 23, the hydrostatic thrust in the float 41 is kept by the water in space 23 even when the water level in cistern 5 falls below the level h. He float 41 guarantees complete emptying of tank 5 and then falls, together with the discharge tube 29, until the ring 31 rests again against the ledge 32.

Since the push button 152 is released so general before float 41 begins to fall, when this happens, the slide 66 returns to its low position, carrying the hook 59 to rest against the sleeve 42. When the float 41 returns to low position, hook 59 reengages the edge upper of the sleeve 42 so that the float 41 is fixed of new in its low position.

Therefore, the advantages of control device of the invention with respect to the known devices In particular, the hook 59 mounted on the Lever 63 makes the device simpler and more economical. In addition, the operating force on the push button 152 for emptying complete is much smaller, since hook 59 is put on operation at the end of the push button stroke without having that simultaneously raise the tube 29.

Instead, the operation of the discharge tube 29 by tab 129, in which a controllable element acts transversely 102, allows wide tolerance limits of the possible misalignment of the two holes 7 and 87 in the tank 5. Finally, the assembly supported by connector 81 can be mounted  together with the push rod 82 without removing it from the pin 83.

It is understood that several can be introduced modifications and improvements to the control device described without therefore depart from the scope of the claims. For example, lever 63 can be replaced by a different element to transmit the movement between the connecting rod 39 and the hook 59. In addition, the slide 66 can be removed by connecting the pin 67 to the connecting rod 39 to obtain the necessary lost movement. Finally, the two push buttons 151 and 152 can be replaced by a single operable push button with two different runs, to control the partial and total emptying of the cistern 5.
