Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a water washing device for supplying a water amount selected by a user from a plurality of specific water amounts.

[0002]

2. Description of the Related Art The amount of water consumed by using a flushing device in a toilet is very large, and the amount of water drained by this is the amount of water required to wash the toilet bowl of the toilet in a satisfactory manner by flowing water. Is often far exceeded. this is,
This is because, in the conventional device, every time the user flushes the water, all the water in the aquarium is drained.This aquarium ensures that the organic substances in the toilet bowl are excreted even in the most difficult cases.
It is sized to store a sufficient amount of water. Such an amount of water is clearly extremely excessive when the toilet bowl contains only liquid excrement.

In order to save water by reducing the amount of drainage and to reduce the cost of water purification, there are already some flushing devices that set two predetermined amounts of water to be flushed in the toilet bowl of the toilet and allow the user to select them. Proposed. But,
The device proposed so far, which allows what can be termed a "double flush", still requires the use of two scarling valves (French Utility Model No. 23729).
37 and French Patent No. 2423594). The first conclusion from such an aspect is that the proposed device cannot be adapted in a simple manner to existing "single flush" devices. Moreover, the cost of flushing equipment is increased due to the need to use two valves instead of one. further,
French Patent No. 2420612 proposes to arrange the two valves of the flushing device coaxially in order to reduce the overall size of the assembly. The traction force applied by the user to one control button causes one or the other of these valves to be actuated by this control button.

[0004]

For the sake of simplicity and to improve the adaptability of the double flush device to existing tanks, French patent FR 2473586 likewise proposes a device with two valves. is doing. The first valve is a state of the art valve located at the base of a vertical tube and the second valve has a cover that seals the top of the tube.
In conventional flushing equipment, this pipe is an overflow pipe, which can drain the water in the aquarium as soon as it reaches its maximum level. Placing the cover over this tube, of course, eliminates the overflow drain feature that it has in conventional devices. The control member has an axial rod that operates the lower valve and a sleeve that surrounds the rod and operates the cover. When the sleeve is pulled, the water located above the cover flows through the shaft tube. Pulling on the rod raises the assembly consisting of the shaft tube and its cover, completely emptying the aquarium through the lower valve. In addition to the disadvantages of the presence of the second valve, this device also has the drawback of eliminating the overflow function of the shaft tube. It is intended to restore this function by forming a vertical port in the sleeve associated with the cover, but this type of port does not have sufficient open area to ensure a safe overflow function.

An object of the present invention is to provide a water washing device capable of reliably supplying a water amount selected by a user from a plurality of preset water amounts.

[0006]

SUMMARY OF THE INVENTION The present invention relates to a water washing device for supplying a water amount selected by a user from a plurality of set water amounts. This device has a water tank with a water inlet,
A control member having a plurality of elements that are adapted to be operated in the upper part of the aquarium and operated independently of each other; It has a movable head that is integral with a support that ensures it on one side, and a scarring valve that has a seat that is integral with the bottom of the water tank on the other side. Each element of the control member may cooperate with a movable head support of the valve to translate the movable head relative to the seat of the valve. The support is provided with n holding means facing n (n is an integer larger than 1) block systems that operate independently of each other. The presence of water in the aquarium, depending on the level of the water in the aquarium, produces a thrust which ensures that at least one block system cooperates with a holding means corresponding to the block system of the n block systems. In one and / or the other so that one of the elements of the control member maintains this position when the support of the movable head of the valve is in the open position of the valve, causing almost complete drainage of the water from the aquarium. This terminates the cooperation of all blocking systems and their associated holding means and the valve is closed by gravity.

The support holding means is a protrusion provided on the outer surface of the support. Each block system is
Preferably, a boss that moves with respect to the support according to the level of water in the aquarium is provided, and the boss is shared with the protrusion corresponding to the boss by buoyancy due to the presence of water in the aquarium. When the thrust acts, the force of gravity causes the protrusion to move away from the protrusion. Each block system has a lever rotatably supported on a shaft fixed to the aquarium, the lever having a float on one side of the shaft and a boss on the other side. Equipped with. The lever provided with the float has an arm to which the float is attached, and the position of the float with respect to the arm is adjusted. The lever arm with the float comprises a rack, the float being integral with a pawl that engages the rack. Each of the protrusions has a sawtooth shape, and one side thereof forms an inclined portion forming an acute angle with respect to the center line of the support of the valve head, and the apex of the acute angle is opposite to the side of the valve head. On the side. The other side of the protrusion is substantially perpendicular to the centerline of the support so that the abutment of the retaining means with the corresponding block system is formed.

According to a preferred variant, the other side of the projection is substantially perpendicular to the center line of the support, so that the abutment of the holding means against the corresponding block system is formed. ing.

Each element of the control member is a push button that is moved by a translational motion by a user's operation, and each push button has a different stroke, and the holding means provides a motion transmission rate to the support. Taking into account, all of the elements of the control means operate on one control rod, offset from each other by a distance which approximately corresponds to the difference in stroke of the pushbuttons. The control rod is preferably such that when the user depresses the push button,
The support of the valve head is moved upwards via a lever. When the user stops pressing the push button, the push button returns to its original position by means of at least one spring arranged inside the mounting of the control means.

In the preferred embodiment, the valve head support is a tube open at both ends. A valve is annularly arranged around the tube. The pipe reliably drains overflow water from the aquarium.

The device according to the invention is especially suitable for "double flushing".
, I.e., when n equals 2. In this case, the two levers forming the block system are preferably arranged side by side on two substantially parallel planes, respectively, so that they can be pivoted on the same shaft arranged on a plate integrally formed with the valve seat. Supported. Each of the bosses has a cylindrical profile, and the outer peripheral surface thereof is parallel to the axis of the shaft. The contact between each boss and its associated protrusion is approximately along the outer periphery of the boss. The plane perpendicular to the contour of the boss on the contacting outer peripheral surface may include the axis of the pivot shaft of the lever. The plate comprises a sleeve in its central part, the support of the valve head sliding in said sleeve. The sleeve is provided with an opening in its side wall, through which the protrusion of the support can freely pass. A stopper integral with the valve seat may be formed such that each lever is placed in an open position with respect to the protrusion.

[0012]

When the water is present in the aquarium, thrust is generated in one block system depending on the level of the water in the aquarium, and the block system is engaged with the holding means. This allows
The control of the movable head of the valve is held in this position by one of the elements of the control member when it is in the open position of the valve, and when the water has almost completely drained from the tank, all the block systems and their associated holding means And the valve is closed by gravity.

[0013]

The other end of the sleeve 14 is supported by a connecting piece 15 through which the rod 13 penetrates. The connecting piece 15 has an opening in the side wall defined by the two flanges 16, and an arm 17 is arranged between the two flanges. The arm 17 is rotatably supported between the both flanges 16 by a shaft 18 which is provided on both the flanges 16. The arm 17 supports the base end of the rod 13 by simply resting it on one end.
The other end of the arm 17 is connected to the rod 19. The shaft 18 is arranged between these two ends of the arm 17. One end of the rod 19 has an arm 17
The other end is bent so as to be hooked on the protrusion 20 integrated with the overflow pipe 21. The connection piece 15 is fixed to the end piece 24 of the fixed rod 23 via the base end portion 15a. The fixed rod 23 is arranged along the axis of the overflow pipe 21.

The upper portion of the overflow pipe 21 has a slightly conical shape, and the lower portion has a cylindrical shape. The lower portion of the overflow pipe 21 is integrated with an annular valve head 25 that operates integrally with the annular valve seat 26. A central portion, whose range is defined by the sheet 26, forms an inlet of the pipe 27, which penetrates the bottom of the water tank and is connected to the pipe 7. Pipe 27
Has an eccentric ring 27 a, which radius centering arm 27 b is the base end portion of the stationary rod 23 supports the bushing 27 c is fixed. Seat 26 and pipe 2
7 is integrated with an annular base member fixed to the bottom of the water tank 1 via a seal 28. This base member is
It comprises two brackets 29 which are diametrically opposed to each other, each bracket 29 engaging a plate 30 at its upper part. As shown in FIG. 3, the plate 30 has an arm shape provided in a diametrical direction between the two brackets 29. A sleeve 31 is provided at the center of the arm shape.
The lower part of the overflow pipe 21 penetrates through the inside of the pipe 1. A part of the side wall of the sleeve 31 is open so that the two sawtooth-shaped protrusions 32 and 33 formed on the outer wall of the overflow pipe 21 can freely pass therethrough. As shown in FIG. 6, the overflow pipe 21 includes two ribs 31 a formed on the side opposite to the openings for allowing the protrusions 32 and 33 of the sleeve 31 to pass therethrough, and the overflow pipe 21.
The three ribs 21 a formed in the sleeve 31
Guided and directed within. One of the sleeve 21 a is slid between the two ribs 31 a. As shown in FIG. 7, the projecting portions 32 and 33 become the same shape, the inclined portions 32 a and 33 respectively the top of the corner becomes the cover 2 side becomes the axis at an acute angle of the overflow pipe 21
a . These two ramps 32 a and 33
The a is connected to the wall portion of the overflow pipe 21 by bottom portions 32 b and 33 b that are substantially perpendicular to the axis of the overflow pipe 21.

Plate 30, as shown in FIG. 3, has two parallel levers 34 and 35 rotatably supported on a single shaft 36 mounted on plate 30. The levers 34 and 35 have the same shape, and as shown in FIG. 8, the arms formed by the arms 34 a and 35 a surrounded by straight lines are very short as compared with the arms. Arms 34 b and 35 b (see FIG. 7) that form an acute angle with the arm. As shown in FIG. 7, bosses 37 and 38 are formed at the tips of the arms 34 b and 35 b , respectively. The bosses 37 and 38 have a cylindrical outer shape, and the axes of the cylinders of the bosses 37 and 38 are parallel to the shaft 36. When the levers 34 and 35 are rotated around the shaft 36, they come into contact with the wall portion of the overflow pipe 21. In this case, the center lines of the arms 34 a and 35 a are parallel to the axis of the overflow pipe 21. Levers 34, 35
Has protrusions 34 c and 35 c , respectively, as shown in FIG. 8, and these have arms 34 c and 35 c as shown in FIG.
When the center lines of a 1 and 35 a are parallel to the axis of the overflow pipe 21, they abut on the stopper 30 a integrated with the plate 30. The overflow pipe 21 is the rod 19
As it is pulled upward by the boss 37
And 38 occupy different positions with respect to the serrated projections 32 and 33. The sawtooth-shaped protrusion 32 is parallel to the other protrusion 33, but the pushbuttons 11 and 1 are taken into consideration in consideration of the transmission rate formed by the lever 17.
The protrusion 32 is offset more toward the bottom than the protrusion 33 by a length corresponding to the difference in stroke between the protrusions 32 and 2.

In the rest state shown in FIG. 2, the two bosses 37 and 38 have two serrated projections 32 and 3.
It contacts the wall portion of the overflow pipe 21 above 3. When one of the push buttons 12 is pressed, the two bosses 37 and 38 similarly come into contact with the wall portion of the overflow pipe 21 as shown in FIG.
Below each protrusion 32, 33, one protrusion 32
Contacts the boss 37. On the other hand, when the push button 11 is pressed, the boss 37 moves to the inclined portion 3 as shown in FIG.
2a , the boss 38 abuts on the wall of the overflow pipe 21, and the protrusion 33 presses the boss 38 (see FIG. 9). The contact between the side portions 32 b and 33 b of each of the protrusions 32 and 33 and the bosses 37 and 38 of the other is made along the circumferential surfaces of these bosses.
The plane perpendicular to the contour of the boss along this circumferential surface passes through the axis of the hinge shaft 36 so that the lever 34 or 35 overflows when the corresponding protrusion 32 or 33 abuts the associated boss 37 or 38. The tube 21 is rotated without pulling it up.

[0018] The lever 34 and 35, the arm 34 a, 3 of
As shown in FIG. 2, 5 a includes floats 39 and 40, respectively. Each of these arms 34 a, 35 a, and sawtooth rack is formed on one of the peripheral portions, each float 39, 40, the corresponding pawl 39 with the teeth engage the rack arm for a, 40 Connected to a , the position of the float along the arm can be adjusted as desired. The float 39 associated with the lever 34 is located at the bottom of the surface 34 a near the shaft 36. Float 4
0 is placed at a higher level, and this level determines the amount of water when performing a partial water wash, as described below. The floats 39 and 40 are manufactured by any method, such as using a bell shape with an open bottom.

Next, the operation of the above-mentioned device will be described in detail. FIG. 2 shows the stationary state of this device. In this state,
The center lines of the two arms 34 a and 35 a are parallel to the axis of the overflow pipe 21. The two bosses 37, 38
Overflow pipe 21 above protrusions 32 and 33
Is in contact with the wall of the. The space between the valve head 25 and the valve seat 26 is closed. The level of water in the aquarium 1 is determined by the constant level cock 4.

When the user pushes the push button 12 of the control member, the rod 13 is lowered by the maximum moving distance, and the overflow pipe 21 is pulled up by the lever 17 and the rod 19 by the maximum moving distance (see FIG. 4). In this state, the space between the valve head 25 and the valve seat 26 is wide open. During the raising of the overhead tube 21, the two bosses 37, 38 are respectively provided with ramps 32 a ,
33 on a slide, contact thereto back to the wall portion of the projecting portions 32 and 33 from the lower overflow pipe 21. When the user releases the push button 12, the protrusion 32 vertically contacts the boss 37. Two levers 34
And 35 are held in the initial position due to the buoyancy on each float 39 and 40. As a result, boss 3
Since the protrusion 32 is supported on the lever 7, the lever 34 is not rotated and the overflow pipe 21 remains in contact with the boss 37. When the water level reaches the bottom of the float 40, the weight of the float causes the lever 35 to rotate. Since the overflow pipe 21 contacts only the boss 37, it is not affected by this. When the water level reaches the bottom of the float 39, the lever 34 rotates and the protrusion 3
2, the overflow pipe 21 descends due to gravity, so that the valve head 25 and the valve seat 2 are not supported.
6 is closed. Therefore, when the push button 12 is pressed, the water in the aquarium 1 is completely depleted.

When the water tank 1 is emptied and the space between the valve head 25 and the valve seat 26 is closed, the cock 4 is naturally installed.
Again fills the water with the initial position shown in FIG.

When the user presses the push button 11, the rod 13 is pushed down a smaller distance than in the case described above, so that the arm 17 and the rod 19 raise the overflow tube 21 a smaller distance than in the case described above. In this case, the boss 38 is located lower than the protrusion 33, but the boss 37 is in contact with the inclined portion 32 a of the protrusion 32. When the user releases the push button 11, the overflow pipe 21 comes into contact with the boss 38 via the bottom 33 b of the protrusion 33. The position of lever 35 is maintained despite the pressure exerted on boss 38 due to the buoyancy exerted on float 44. As a result of the rise of the overflow pipe 21, the space between the valve head 25 and the valve seat 26 is opened, so that water flows out of the aquarium, but when the water level reaches the bottom of the float 40, as shown in FIG. 35 rotates by the weight of the float 40. This rotation is performed despite the support by the protrusion 33 because the outer shape of the boss 38 is special. The overflow pipe 21 is lowered due to gravity due to lack of support, and the valve head 25 and the valve seat 26 are closed. When the overflow pipe 21 moves in this way, the boss 37 slides along the inclined portion 32 a and returns to the wall of the overflow pipe 21 to abut. Therefore, when the user presses the push button 11, the water in the aquarium 1 disappears to the level below the float 40.

According to the above device, the user controls the control member 9
Depending on whether you press push button 11 or 12,
It is possible to obtain a "double wash". By pushing the push button 12, the water in the aquarium 1 is completely removed, and washing with a large amount of water is performed. By pressing the push button 11, the float 40 is no longer aquarium water to the level determined by where it is in such a position with respect to the arm 35 a, little washing with water is carried out. This "double flush" device is attached to an already installed aquarium. This includes a new plate 30 with levers 34 and 35 connected to the overflow pipe 21 and the control member 9, a valve head 25 already fixed to the bottom of the aquarium 1, a valve seat 26, a pipe 27, a seal 28, a bracket. It suffices to deploy on one single component forming 29, and the assembly of these components forms the replacement kit. Therefore, there is no need to modify the aquarium and the seat components integral therewith.

The embodiments described above are of course not limiting of the invention, and any desired modifications are possible without departing from the scope of the invention. In particular, when the bosses 37 and 38 move away from the wall of the overflow tube 21, the levers 34, 3
A stopper that restricts the passage of 5 may be arranged on the plate 30.

FIG. 12 shows a preferred variant embodiment of the serrated projections 132, 133 arranged on the wall of the overflow pipe 121.

As in the case of FIG. 9, one side portion of each protruding portion forms an acute angle with the axial center line of the overflow pipe 121 which is a support portion of the valve head.
2 a and 133 a . The top of this corner is opposite the top of the valve head. On the other hand, the inclination of the other side portion 132b, 133b (that is, the bottom portion) of the protruding portion with respect to the axial center of the overflow pipe 121 causes the hinge 13 of the connected block system to be supported by the lever 13.
The support force on this side applied to 4,135 is angled to impart rotational momentum to the lever to open the block system.

[0027] In practical use, the supporting force against the protrusion 133, for example F133 is perpendicular to the side 133 b.
The opening is obtained by rotation of the lever 135 about the lowermost shaft 136, in this example clockwise rotation.
Inclination of the side 133 b, the force F133 is to pass through the upper than the distance h (i.e. the lever arm) by axial 136. With this method, the protrusion 133 with respect to the lever 135
The pressure of creates a rotational moment which urges this lever 135 in the clockwise direction, ie in the opening direction. This allows the system to operate efficiently as soon as the float connected to the lever is no longer under water pressure.

When the lever 135 rotates in the clockwise direction, its passage is formed by an arc C. Side 1 above
The inclination of 33 b is such that the side 133 b is raised towards the passage C by an angle e with respect to the tangent T at the point of support of the protrusion and the lever. Therefore, the lever 135
The lever 135 does not have to push the protrusion 133 upwards to facilitate opening when the is rotated in a clockwise direction.

Of course, the same can also apply to the projection 132 and the lever 134, which are likewise pivotally supported about the axis 136.

[0030]

The "multi-flush" system of the present invention, like the conventional "single-flush" device, uses only one valve, and therefore the "single-flush" installed in the currently installed aquarium. It can be adapted to the device in a simple way. Furthermore, the fact that no auxiliary valve is required is a favorable factor in terms of the cost of the device. In the device according to the invention, the axial tube associated with the valve holds the overflow discharge function. According to the invention, for a "multi-flush" device, only one valve of the device is open until the water in the aquarium reaches a certain level. The choice of this level is determined by the control elements operated by the user to perform the flush. In other words, the choice of water flow is
It is determined by opening the valve until the water level reaches the desired height, rather than by the choice of the valve being placed in the aquarium in a suitable manner. If it is desired to be able to choose between more than two water quantity selection branches, conventional devices require as many valves as there are water quantity selection branches to operate. In the device according to the invention, on the other hand, the number of blocking systems is the same as the number of selective branches of the desired amount of water, but only one valve is associated with this valve.
