Technical Field of the Invention

The subject-matter of the invention generally falls within the area of toilet flushing reservoirs, and specifically relates to the toilet flushing tanks with balancing reservoir, which can be installed as in-wall (concealed), high-mounted / low-mounted, directly on the toilet bowl, and with electronic flush control.

According to the International Patent Classification (IPC), the invention is classified and indicated by the classification symbols: E03D1 / 20, E03D1 / 14, E03D5 / 09.

Technical Problem

The technical problem solved by this invention is the following: construction of a toilet flushing tank that can be installed as in-wall (concealed), high-mounted, low-mounted, directly on the toilet bowl, and with electronic flush control, and with a balancing reservoir which, upon pushing a lever or touching a screen, allows water to be released as desired, from minimum to full emptying, thus preventing uncontrolled water leakage from the tank. The invention provides long-term use without special maintenance and elimination of unpleasant odors by air exhaustion from the toilet through the flush tank and ventilation system outside the room where the toilet is located.

Existing technical solutions

There are different generally known types of toilet tank/cistern units - BUILT-IN (CONCEALED), MONOBLOC, LOW INSTALLATION, HIGH INSTALLATION, with mechanical and electronic flushing operation, and with similar mechanical elements for flush control, mainly dual flush (smaller and larger amount of water). These types of units generally have a problem with lime deposits on flushing mechanisms, resulting in undesirable leakage over time and creating unnecessary losses of drinking water and higher costs. In addition, frequent cleaning of lime deposits is necessary on a large number of tanks, and after many years of use they must be replaced.

A research into the patent documents pertinent to this area did not find a similar technical solution. The following documents are cited as coming close: DE19504783 (Al) - 1996-08-22; FR8291147 (A) - 1938-06-13; FR2936000 (Bl) - 2014-04- 11

DE10324856 (Al) - 2004-12-30.

The essence of the invention

The essence of the invention is in the construction of the toilet tank/cistern, consisting of: the body, balancing tank with affixed balancer, and a shaft running from the back of the body through the balancer and affixed at the center of the discharge at the front of the tank body. On this side there is also an opening to which a tunnel with a protector is mounted, with an opening for a handle connected to a pull button which, when pulled, causes the balancing tank to rotate, discharging the water into the space between the body and the balancing tank, and after that through the opening at the bottom of the cistern directly to the toilet.

The essence of the invention is also reflected in the fact that the tank/cistern design completely eliminates the need for interventions due to scale build-up on the water discharge mechanism, noting that flush regulation (from small to maximum water amount), whether mechanical or electronic type, achieves significant savings, which is especially important when using multiple units, e.g. in public institutions, schools, hospitals, etc.

Another essential aspect of the patent is the balancing tank with attached balancer with chambers and openings that allow gradual fill-up and discharge of water, keeping the balancer in a rotated position for as long as its effective emptying requires, and then easy return to the initial position.

What makes this unit completely different from numerous similar products is the application of a balancing tank, which renders lime scale deposits irrelevant for efficient operation, which is extremely important as it completely prevents uncontrolled water leakage. We particularly stress the fact that the amount of water used for flushing is not reduced to just two possibilities but the flushing of the toilet bowl is performed several times in succession, by releasing water from the minimum to the maximum amount. In addition, the air remains constantly clean, as odors are exhausted from the toilet by a fan through the supply pipe and flushing cistern and through the ventilation pipes outside the toilet room.

It should also be emphasized that no water droplets condense on the cistern in question, because water is not in direct contact with the external body of the cistern, which is especially important for built-in models as there is no wall humidity. The life span of such a cistern is virtually unlimited, so service and maintenance are almost completely eliminated. A novelty of the invention is that there are openings on the cistern, positioned to allow simple and easy installation of exhaustion fans for unpleasant odors, which is significant from the aspect of comfort of modern consumers: with slight structural modifications this unit is easily applied as built-in, atop the bowl, low-mounting or high-mounting, with both mechanical and electronic controls, making it compatible with various architectural requirements.

The invention can be regarded as“green” because it brings significant water saving, which is becoming increasingly more important each day.

Detailed description of the invention

The basic solution of the present invention is a built-in mechanical cistern, shown in Figures 1 to 53 and 92 to 97, consisting of: balancer 204 in the form of two plates 37 and 38, interconnected at their circumference by a wall 48 with openings 41, 42 for water intake and opening 45 for water discharge. The balancer also has a partition wall 39 with openings 43 and 44 for water discharge. The partition wall 39 divides the interior of the balancer into two chambers 46 and 74. The balancer 204 is rigidly coupled to the balancing tank 203, relying on the bracket 29 with its semicircular ring 40, and being drawn by its groove 36 to the cog 35 of the balancing tank 203, which is made in the form of two plates 26 and 27 chamfered by radius 31 at height h from the center of radius 31. The front and back panels are interconnected along the rim by the wall 28 and the holder 29 with the hole 33 for the shaft 23. On the outer side 27 there is a circular annular outlet 32. The balancer 204 and the balancing tank 203 are also housed in a body 201 with a tightly closed lid 202. The body 201 has the front side 1 and the back side 2 plate-shaped panels, made in the lower part by radius 18 and inter-connected by a wall 3.The front 1 of the body 201 has a notch with the lateral edges 9 and on the sides of the inner walls 1 and 2 there are outlets 17 and 16 with a center corresponding with the center of radius 18. Through opening 15 on the side 2 of the body 201 and through opening 30 of the balancing tank 203 passes the shaft 23, which is tightly screwed into the center of the outlet 17 on the side 1 of the body 201. On the rear side 2 there is a stopper 5 with a buffer 20, an opening 6 with a fan 212, an opening 13 for the cable, an opening 12 for water connection and a slanted holder 8 with an opening 14 for the shaft 22 and connector 21. On the wall 3 there is a carrier 11 into which the water level regulator 210 is firmly attached by its outlets 74, which is connected by a nut 81 to the water connection 211, stepper motor mounts 10, the vent 6 for the fan 212 with the cap 24 as well as screw holes 7. At the bottom of the body 201 there is an opening for the pipe 4 for water supply to the toilet bowl.At the side edges 9 of the front 1 of the body 201 there is a tunnel 206 with grooves 51, through which a carrier 207 with outlets 55 is placed. From the rear, the carrier 207 has outlet with an opening 60 through which runs an axle 22 with a connector 21, and on the front there is an outlet 56 to which the lever 209 is attached through the opening 65. At the outlets 57 of the carrier 207, a cover 208 is attached. At rear 2 of the balancing tank 203 there is a hook 86 of the puller 85 which is partially placed over the ring outlet 32 of the tank 203 and goes over the first connector 21 and the second connector 21 through channel 67 and is fixed with a clamp 69 through the opening 66. When filling the balancing tank 203, water is also poured into the balancer 204 through openings 41 and 42 and fills it to the intended level. When the lever 209 is pulled, a puller 85 rotates the balancing tank 203 and the balancer 204 and the water contained in the chambers 46,47 of the balancer 204 acts as counterweight and keeps the balancing tank 203 in a rotated position until water flows out of the chamber 46 into the chamber 47 and through the opening 45 together with the water from the balancing tank 203 into the toilet bowl through the tube 4 The balancing reservoir 203, after rotation, returns to the starting position and fully emptied and then refilled. The body 201 is bolted to the carrier 213 through the holes 7 screwed into the holes 103 with threads and rests on the holders 89 made at the same time on the inner sides of the profile 98, which have recessed threads 94 at their lower ends, which serve to adjust the height and are fixed with two screws 91 screwed into the openings 95 on the rectangular plates 92 .The square profiles 98 are interconnected by a single U profile 97 with openings 90 for securing the toilet bowl and the outlet bracket 100 for supplying the water to the toilet bowl. A square profile 96 with openings 101 and grooves 102 for fixing pipes for drainage of water from the toilet cup is made at the bottom of the carrier.

The variant solution of the balancer 204 shown in figures 24 to 27 is designed to have openings 49 housing the inlets 50.

The tunnel 206 shown in figures 28 to 31 is made in the form of a frame of segments 52 that can be cut as needed. On the inner sides of the segments 52 on both sides there are grooves 53 with outlets 55 of the carrier 20. Tunnel 206 has two runners 51 by which it isattached onto the side edge 9 of the body 201.

Carrier 207 shown in figures 32 to 34 is in the form of a plate having at its rear a bracket with a connector 21 opening 60 for a shaft 22 and an opening 59 for the cable 136. At the front, the plate has a support 56 for the lever 209 , in the frame with outlets on its sides.

The lever 209 shown in figures 38 and 39 at one end has a circular opening 65 by which it is attached to the outlet 56 and at the other end is a circular outlet 64, slid through the slit 62 of the cover 208 . The lever 209 has a channel 67 into which a puller 85 is fixed by means of a clamp 69 through the opening 66 . The lever at the rear has a groove 68 .

The cover 208 shown in figures 36 and 37 has a slot 62 for the lever outlet 64, and at the rear there are outlets 63 which are connected to the carrier outlets 57.

The water level controller 210 shown in figures 42 and 43 is well known in the field and is only schematically shown to prove the feasibility of the invention, making the application simplified and invention easier to understand. The water level controller 210 is pressed through outlets 74 into the carrier 11 of the body 201. As the balancing tank 203 is being filled the float 73 is raised, thereby interrupting the water supply, and when the balancing tank 203 is emptied, float 73 is lowered and water can be refilled to fill up the balancing tank 203.

The water connection 211 with valve 79 shown in figures 44 and 45 is also well known in the field and is only shown schematically for the purpose of proving the feasibility of the invention. The water connection 211 is connected by a nut 81 screwed onto the groove 72 of the water level regulator 210. The fan 212 shown in figures 46 and 47 is standard construction and is only shown schematically. The fan 212 firmly housed in the opening 6 exhausts air through the interior of the cistern, directly from the toilet through the tube 4 and the ventilation tube 128 connected to the ventilation installation.

The puller 85 shown in figures 48 to 50 is made of a flexible material and at one end has a solid bent hook 86 hooked to the rear 27 of the balancing tank 203 and the other end is tightened and fixed by a clamp 69 through the handle opening 66.
