Description

The utility model relates to sanitary equipment, namely, to flush cisterns with double flush for the toilet. The prior art double-flush cisterns containing a casing with a lid, a discharge device with a shut-off valve and a level float and a drain device including a hollow rod with a stop bar and a bottom valve covering the drain neck with an arm, a float dosing mounted on the hollow rod discharge of a small portion of water, an emphasis for the retaining strip installed on the said bracket and a rotary float, dispensing the discharge of all water from the tank in contact with the retaining strip and cut off from to contact with it when draining a small portion of water with a blocking mechanism, a hollow rod lifting lever and a drain device control mechanism made in the form of two handles on the tank body, one of which acts on the hollow rod lifting lever, the other on the blocking lever [1-3 ].

The closest in technical essence to the proposed utility model is a flush cistern with double discharge of water for the toilet, comprising a casing with a lid, a discharge device installed in the casing with a shut-off valve and level float, and a drain device including a hollow rod with a lock bar and a bottom valve that overlaps a drain neck with a bracket mounted on a hollow stem with the possibility of axial movement of the float, dispensing the discharge of a small portion of water installed on the bracket To limit the lifting of the retaining plate and a rotary float, dosing the discharge of all water from the tank and in contact with the locking plate; a locking mechanism mounted on the drain neck post and cutting off the rotary float from the retainer bar with its fork-like thrust when draining a small portion of water, the lever and the lifting rod of the hollow rod located on the said post, as well as the trigger control mechanism in the form of two buttons installed in the hole tank lids, one of which kinematically by means of intermediate elements acts on the lever for lifting the hollow rod, and the other on the lever of the locking mechanism [4].

However, the known drainage devices are complex in design, occupy a significant useful volume of the tank and cannot be used for tanks of various heights.

This is because:

a) well-known drainage devices have only one stop to limit the lifting of the locking bar, therefore, in this case, a blocking mechanism is required to exclude the participation of the rotary float in the mode of draining a small portion of water: otherwise the device will break down and it will drain only all the water from the tank;

b) the well-known drain devices with release buttons are made in the form of a monoblock stand on which the upper part of the device is mounted, which makes the construction cumbersome, in addition, in these devices it is impossible to control the height of the stem, which requires tanks of different heights.

The objective of the utility model is to simplify the design of the drain device and the possibility of using it in tanks of various heights.

This problem is solved in that in a flush tank with a double descent for a toilet, comprising a housing with a lid, a discharge device installed in the housing with a shut-off valve and a level float and a drain device including a hollow rod with a lock bar and a bottom valve that overlaps the drain neck with an arm mounted on a hollow stem with the possibility of axial movement of the float, dispensing discharge of a small portion of water, an emphasis installed on the bracket to limit the lifting of the retaining plate and the rotary the second float, dispensing the discharge of all water from the tank and in contact with the retainer plate, a blocking mechanism mounted on the drain neck stand and cutting off the rotary float from the retainer plate when draining a small portion of water, the lever and the rod for lifting the hollow rod located on the above-mentioned rack, as well as a control mechanism for the drain device in the form of two buttons installed in the hole of the tank lid, one of which kinematically acts on the lever for lifting the hollow rod, and the other on the lever of the locking mechanism, according to the field heat model:

a) the drain device is equipped with an additional stop for restricting the lifting of the locking bar made on the rotary float - thus, when draining a small portion of water, the rotary float acts as a stop for the locking bar, it takes a direct part in this mode of operation of the drain device, without disrupting its operation, which eliminates the locking mechanism, simplifying the design of the drain device;

b) the lever for lifting the hollow rod is installed on the tide of the sleeve located in the hole of the tank cover and is directly connected to one of the buttons - this eliminates the bulky rack, as well as intermediate elements between the lever and the button, which also simplifies the design of the device;

c) the connection of the lifting rod with the hollow rod is adjustable, for example, screw, and at least its upper part is made of flexible material, while the hollow rod is equipped with a nozzle with the ability to adjust the height of the tank - this allows you to use the drain device in tanks of different heights.

Figure 1 shows a sectional view of a flushing cistern with dual trigger buttons on the lid and side supply of water to the cistern; figure 2 shows the position of the parts of the drain device when draining all the water from the tank; figure 3 - the same when draining a small portion (half) of water from the tank; figure 4 shows details of the upper part of the drain device; figure 5 shows the relative position of the parts of the lower part of the drain device in a perspective view. Figure 6 shows a prototype of the drain device.

Flushing tank for the toilet contains a housing 1, a cover 2, a filling and drain device.

The filling device consists of a shut-off valve 3 connected by means of a lever 4 to a level float 5 [Fig. 1].

The drain device of the tank contains a hollow rod 6 mounted on a cross-shaped guide 7 of the drain neck 8 and made integral with the bottom valve containing a rubber cuff 9 that overlaps the drain neck. The rod 6 serves as an overflow pipe at a critical water level in the tank, its upper part 10 is elongated as a nozzle cut off when adjusting the tanks of different heights; the side is made in the form of a gear rack 11, along which the central float 12 with the spring tooth 13 moves, dispensing the discharge from the tank of a small portion of water (half tank). On the drain neck 8, an L-shaped bracket 14 is made, on tides 15 with stops 16 of which a float 17 rotatable in a vertical plane is fixed, dispensing the discharge of all water from the tank, the geese of the float 17 are equipped with a stop 18. An open vertical groove 19 is made in the bracket 14, which is a guide for the lower of the two consoles 20 of the rod holding the retaining plate 21, at the top of the plate has an opening 22 with a screw thread, and at the bottom is provided with a protrusion boot 23.

The bracket 14 has a stop 24 and can springy spring apart when assembling the device for the passage of the console 20. In the hole of the lid 2 of the tank with a nut 25, a sleeve 26 is attached [Fig. 4], in the vertical trunks 27 and 28 of which the legs of the fungal release buttons are moved: 29 - a larger diameter to drain all the water from the tank and 30 - a smaller diameter to drain part (half) of the water; the button caps are located in the nut 25, there is a window 31 in the button leg 29, and a spike 32 protrudes from the side, which is located under the small button cap during assembly; in the leg of the small button 30, a restriction step 33 is made and there is a groove for the passage of the spike 32. The sleeve 26 has a tide 34, on which the lever 35 is pivotally mounted; the small lever arm is mounted in the window 31 of the large button, and the large one is connected to the rod 36 [Fig. 5] having a flexible upper part and a screw thread in the lower rod portion 37, by means of which the rod 36 is connected to the retainer plate 21.

Flushing tank for the toilet is as follows. When draining a small portion of water (half bottle) (Fig. 3), press the small button 30, which, lowering the stop of the step 33 into the sleeve 26, through the spike 32 forces the large button 29 to lower, which, in turn, presses on the small lever arm 35; the lever, turning, lifts the retaining plate 21 with the rod 6 with the help of the thrust 36, while the retaining plate 21 rises along the bracket 14 by such a value that its protrusion 23 does not step over the stop 18 on the goose of the rotary float 17, but remains under it: small button 30 is not enough for this. Under the influence of the buoyancy force of water, the rotary float 17 will turn to the left to the stop 16, and the central float 12 will tend to float with the rod, but will only reach the contact of the protrusion 23 of the retainer plate 21 with the stop 18 of the rotary float: the water force acting on the rotary float 17, will stop the rise of the stem - the drain neck is open for draining, and the bottom valve is fixed in the open position. As the water drains from the tank, the buoyant force acting on the central float 12 decreases, and the stem 6 lowers - the bottom valve will block the drain neck. At the same time, the level float 5 is lowered, opening the passage of water from the line to the tank through the shutoff valve 3.

To drain all the water from the tank, press the large button 29 (Fig.2). In this case, the lever 35, the thrust 36, the rotary float 17 and the rod 6 with the retaining plate 21 make the same movements as when draining a small portion, only now the locking bar 21 will rise to a great height - to the stop of the console 20 at the stop 24 - so its protrusion 23 will be above the stop 18 of the float 17: the stroke of the large button for

this is enough, because there is no restrictive step in it, and the emphasis 18 is pushed to the side for the passage of the protrusion 23 of the locking bar and pops under it, not allowing the locking bar 21 to fall; this fixes the stem 6 and the open position of the bottom valve.

After draining all the water from the tank, the buoyant force ceases to act and the float 17, falling under its own weight, removes the stop 18 from under the retaining plate 21, the stem 6 will lower, all the elements of the drain device will return to their original position, and the bottom valve will close the drain neck, and the filling device will again fill the tank with water to a certain level.

Thus, the drainage device has two stops to limit the lifting of the locking bar - stop 18, which acts when draining a small portion of water, and stop 24, which acts when draining all water from the tank - and works without a blocking mechanism.

The regulation of flushing tanks is as follows.

The water level in the tank filled with the filling device is determined by the level of its float 5 and is controlled by moving the latter along the lever 4. The amount of draining a small portion of the water from the tank is adjusted by moving the central float 12 along the rod 6.

For tanks of various heights, the adjustment of the length of the rod 36 from the lower part of the drain device is carried out by screwing (unscrewing) its lower screw end 37 into the hole 22 of the retaining plate 21, and the height of the hollow rod b is adjusted by cutting its upper nozzle part 10 to the height required for this barrel .

To connect the lower part of the drain device with the upper one when assembling the tank, the upper end of the rod 36 is raised and, slightly bent, put it on the lever 35 installed in the tank cap.
