Description of the invention

An object of the present invention relates to a flushing device mounted on a ceramic sanitary product to enable flushing of a bowl of a ceramic sanitary product, and to a method for flushing a bowl using this system.

Below will be described the use of the device (A) for flushing, developed within the scope of the present invention, on the toilet.

The flushing device (A) according to the present invention comprises at least one inner case (1), at least one outer case (2), at least one cover (3) and at least one speed adjusting part (4) flow.

The flushing device (A) according to the present invention further comprises fasteners (5), fasteners (8), sealing elements (6) on the outer casing and sealing elements (9) on the inner casing. A flushing device (A) developed within the scope of the present invention can be used both in the presence and absence of a bidet system. If the device is used in the presence of a bidet system, it contains at least one bidet nozzle (16), at least one bidet nozzle gasket (24) and at least one hole (3a) on the cover (3) for accommodating the nozzle (16) ) bidet. If the device is used in the presence of a bidet system, at least one bidet conduit (17) is attached to the installation section (10) of the bidet conduit on the outer casing (2) using at least one gear part (18).

Regarding the sealing elements used in the flushing device developed within the scope of the present invention, the sealing element (6) located on the outer casing is preferably a gasket providing a seal between the surface of the toilet and the device according to the present invention. Each of the sealing elements (9) located on the inner housing preferably is a sealing ring located in at least one groove (1a) for the sealing element on the inner housing (1). A flushing device (A) developed within the scope of the present invention is shown in FIG. 1 in a state when used in a toilet without a bidet system, and in FIG. 5 and 6 are in a state when applied with a bidet system.

The flushing device (A) according to the present invention is installed at the end of the clean water channel (26) on the toilet, that is, in the socket (27) located in this position. Also, a flushing device (A) developed within the scope of the present invention can be used in rimless toilets on the inside of the bowl. No nozzle is used to direct water to the device according to the present invention. Unlike the systems used according to the prior art, the water does not come from the water system, but from the tank (25), and flows through the channel (26) for clean water, reaching the flushing device (A) according to the present invention. A flushing device (A) developed within the scope of the present invention can be used with or without a bidet system.

While using systems provided in the prior art, the toilet allows flushing with water entering through openings or openings made on the toilet, in the case of the flushing device (A) according to the present invention, flushing is carried out using the device (A) for flushing installed on the product as a follow-up. To use the device (A) for flushing, developed within the scope of the present invention, a toilet must be provided with a socket (27) of an appropriate size, allowing installation of the device (Fig. 11). This nest (27) is located at the end of the channel (26) for clean water. In this socket (27), the outer casing (2) of the flushing device with the sealing element (6) fitted on the outer casing is installed.

The outer casing (2) of the flushing device is mounted on the toilet with fasteners (5) and fasteners (8). The outer casing (2) contains fixing legs (14) for placement on the fastener (5). The fasteners (5) contain both grooves (5a) for placing the legs on the outer casing where the fastening legs (14) of the outer casing should be placed, and grooves (5b) for the fastening elements where the fastening elements (8) should be placed ) As seen in FIG. 10c, the outer casing (2) comprises at least one opening (2b) for attaching a bidet nozzle and at least one groove (2a) for the fastener on its inner section. The outer housing (2) according to the present invention contains at least three holes, namely: one hole (2b) for attaching a bidet nozzle and two grooves (2a) for fasteners. The fixing legs (14) on the outer case enter the corresponding grooves (5a) on the fasteners to place the legs on the outer case, and the fasteners (8) are placed both in the grooves (5a) for the fasteners on the fasteners and in the grooves ( 2a) for fasteners on the outer case (2), and thus the fasteners (5) are fixed on the outer case (2), as seen in FIG. 4e. Fasteners (8) can be attached using at least one washer (7). However, if the fasteners (8) are not tightened, the fasteners (5) can move on the outer case (2). Thus, the fasteners (5) fitted to the outer casing (2) are pushed forward when passing through the socket (27) on the toilet and take an inclined position in the horizontal direction, and they pass through the socket (27) in this state. After tightening the fasteners (8), they become straightened in the horizontal direction and, since they are longer than the width of the specified socket (27), their passage through the socket (27) is prevented, and the outer case (2) becomes securely fixed in the socket (27) . Each of these fasteners (8) is preferably a screw. The outer housing (2) contains at least one installation section (10) of the bidet conduit and, in the case of using the flushing device (A) according to the present invention, together with the bidet system, at least one bidet conduit (17) is installed in this sections. The installation section (10) of the bidet conduit contains at least one gear section (10a), and the conduit (17) for the bidet is mounted on this section using at least one gear part (18).

In FIG. 8a-8g show an inner case (1) consisting of a device developed within the scope of the present invention. The inner housing (1) comprises at least one groove (1a) for the sealing element, in which at least one sealing element (9) must be placed on the inner housing. A sealing element (9) on the inner case is housed in said groove, and said sealing element according to a preferred method of use is a sealing ring. Thanks to the indicated sealing elements (9) on the inner case, the inner case (1) is fixed inside the outer case (2) by the exact fit method. In FIG. 4a-4f show the inner case (1) in the installed state on the outer case (2). The inner housing (1) comprises at least one fully open side channel (12), at least one partially open and partially closed side channel (13), and at least one middle channel (11).

The specified fully open side channel (12) and the specified partially open and partially closed side channel (13) are located on the right and left sides relative to the center (1b) of the inner casing, and the middle channel (11) is placed between the fully open side channel (12) and a partially open and partially closed side channel (13) in the lower section of the inner case so that it is located on the same axis with the center (1b) of the inner case. Water flows through these channels into the toilet and performs the flushing process. One of the side channels is open for the flow of water in one part and closed in the other part. As seen in FIG. 4f, in order to obtain a more efficient flow of water and a more satisfactory flushing process, the partially open and partially closed side channel (13) contains at least one open part (13a) of the side channel and at least one closed part (13b) of the side channel . Another completely open lateral channel (12) is a channel open throughout its length. In a partially open and partially closed side channel (13), the open part (13a) of the side channel has a cross-sectional area in the range of 80-100 mm ² , and another fully open side channel (12) has a cross-sectional area in the range of 240-300 mm ² . The difference in the diameters of the water discharge openings in the two side channels prevents the jets of water from connecting in the front of the toilet, while the water jets flowing from the fully open side channel (12) and the partially open and partially closed side channel (13) and moving along the toilet are connected on the right or left side edge (28) of the toilet bowl and merge into the toilet bowl. In FIG. 19 shows the fusion of water (Y) in the front of the toilet according to the prior art. The fact that the water discharge openings in the fully open side channel (12) and the partially open and partially closed side channel (13) are of different sizes causes water to move along the two side edges (28) of the toilet with different speeds. Due to the faster movement of water, which results in the presence of a side channel in the open part (13a) of a smaller cross-sectional area or diameter, the water moves a greater distance along the water bowl, and the merging occurs at a point near the point for the discharge of water leading from another, fully open side channel (12). Depending on the diameter of the open part (13a) of the side channel, water jets flowing from the fully open side channel (12) and from the partially open and partially closed side channel (13) can be connected at various points on the toilet to drain into the toilet, as shown in FIG. 18. Water jets moving along the two lateral edges (28) of the toilet can be connected at a point near the fully open side channel (12), which has a larger diameter; in other words, they can be connected at the lateral edge (28) of the toilet at a point on the lateral edge (28) in a section with a fully open lateral channel (12) having a larger diameter, which forms a confluence line (D) drawn from the channel for clean water to the center (C) of the toilet, an angle with any value in the range of 60-120 °. And from this point, the drained water flows into the toilet. In FIG. 19 shows the fusion of water (Y) in flushing systems used according to the prior art, where water jets move at an equal distance along both lateral edges of the toilet bowl and are connected at a point exactly in front of the toilet bowl equidistant from both outlet points, and in FIG. 19a shows the merging of water (X) in the case of using the flushing device according to the present invention, where the water jet flowing from the small-diameter opening moves faster, and the water jet flowing from both channels are connected on the side edge (28) of the toilet bowl. The fact that the jets of water flowing from both side channels, are moving at equal speeds and have equal effort, leads to the fact that water rises and splashes out of the toilet bowl according to the prior art. In the flushing device (A) developed within the scope of the present invention, the problem of splashing is also eliminated.

Completely open side channel (12) and partially open and partially closed side channel (13) contain arches (15) in their lower sections. These arches (15) provide the possibility of a more efficient flow of water. The inner casing (1) contains on its inner section protrusions (21) on the inner casing to accommodate the part (4) that controls the flow rate. The inner case (1) contains recesses (19) on its surface on the inner case, in which the cover (3) should be placed. According to a preferred method of use, the lid (3) is mounted on the inner case (1) by a bonding process, and said recesses (19) on the inner case provide an opportunity to increase the bonding surface. At least one hole (20) is placed to accommodate the bidet nozzle (16) on the inner housing (1). The inner housing (1) comprises on its inner surface an asymmetric guide (22) with an asymmetric construction, shown in FIG. 8b, 8e, 8f and 8g. The asymmetric guide (22) is visible in detail in FIG. 11a, 11b and 11c. Part (22b) of the asymmetric guide (22) in the section with partially open and partially closed side channel (13) is inclined so that it directs the incoming water in the direction of the open part (13a) of the side channel, i.e., it directs incoming water in an upward direction. On the other hand, part (22a) of the asymmetric guide (22) in the section with the side channel (12) fully open is inclined so that it directs water towards the lower part of the channel, which is open. Thus, jets of water directed by the asymmetric guide (22) at different angles and flowing from both side channels do not connect exactly in the middle of the inside of the toilet, and this prevents water from splashing out of the toilet. The fact that the parts of the side channels in which the water flow is provided have different diameters, in other words, the partially open and partially closed side channel (13) is open in one part and closed in the other part, prevents water leakage from both channels with the same energy.

The bidet nozzle (16) contains at least one groove (16a) for the sealing element for accommodating at least one sealing element, and, thanks to the sealing elements located in the indicated grooves (16a) for the sealing elements, the bidet nozzle (16) is securely attached to the hole (2b) for attaching the bidet nozzle on the outer casing (2) by the exact fit method. In the case where it is required to use the device according to the present invention with a bidet system, the bidet nozzle (16) passes with at least one gasket (24) of the bidet nozzle through the hole (20) on the inner case and is securely attached to the hole (2b) for attaching a bidet nozzle to the outer housing (2) by an exact fit method, as mentioned above.

In FIG. 9a-9b show a part (4) that controls the flow rate contained in the device according to the present invention. The part (4) that controls the flow rate is located on the inner section of the inner case (1). The part (4) that controls the flow rate contains at least two holes for the flow of water, namely: a large hole (4a), having a larger size compared to the other, and a small hole (4b), having a smaller size compared to the other . The flow rate adjusting part (4) in its standard position is located in the inner case (1) so that the large hole (4a) is located on the upper side, as shown in FIG. 1 and 5. In this position, the arrangement is such that water flows through a large opening (4a). However, in cases where the water flowing out of the tank (25) does not have sufficient energy, or when a stronger influx of water is required, the placement can also be done so that a small hole (4b) is located on the upper side. In other words, the arrangement is such that water flows through a small hole (4b). Therefore, the flushing device (A), developed within the scope of the present invention, also becomes effective for increasing the flow rate of water in cases where it is necessary to increase the flow rate in order to achieve a more effective flushing in accordance with the energy of the water flowing from the tank (25). The part (4), regulating the flow rate, contains mounting grooves (23) into which protrusions (21) are introduced on the inner case (1). When introducing the protrusions (21) on the inner case into these mounting grooves (23), the part (4) that controls the flow rate is fixed in the inner case (1).

In the case where the flushing device (A), developed within the scope of the present invention, is used together with a bidet system, the bidet conduit (17) is securely fixed to the installation section (10) of the bidet conduit on the outer casing by means of at least one gear details (18). The gear part (18) is attached to the gear section (10a) on the installation section (10) of the bidet conduit on the outer casing by screwing them together, or fitting the gear surfaces to each other.

Despite the fact that it is possible to make the cover (3) used in the flushing device according to the present invention made of ceramic to ensure harmony with the toilet, the present invention also covers the possibility of making the cover from another material.

Flushing the toilet with the flushing device (A) according to the present invention is based on the principle that water starting to flow freely when the tank button is pressed flows through the clean water channel (26), reaching the device according to the present invention, flows through the outside the housing (2), reaching the inner housing (1), enters the toilet through the middle channel (11), a fully open channel (12) and a partially open and partially closed channel (13), made on the inner case (1), and flushes in the toilet. Water jets flow into the toilet from both the left and right sides through a fully open side channel (12) and a partially open and partially closed channel (13) provided on the inner casing (1), and at the same time, the water stream also directly flows into the toilet downward from the middle channel (11) located in the middle section. The part (4) that controls the flow rate, which is provided on the inner casing (1), is used to adjust the flow rate of water flowing from the tank (25). The flow rate-adjusting part (4) according to the usual standard application is fixed in the inner case (1) so that the large hole (4a) on the indicated part is located on the upper side, as shown in FIG. 1, FIG. 5 and FIG. 6; however, if the flow of water flowing from the tank (25) is not proportional, the flow rate is increased by placing a part (4) that controls the flow rate so that a small hole (4b) is located on the upper side on the specified part.

The flushing device (A) according to the present invention is very useful in that it is easy to install, capable of realizing a flushing process due to the smooth distribution of water flowing from the clean water channel (26), it provides an aesthetic appearance, allows its use in rimless toilets and is easy to clean. In addition, the specified device for flushing can be used in toilets with a bidet system, as well as in toilets without a bidet system. Since it is not a monolithic block and is formed by removable parts, and since it is easy to fit to the toilet and separate from the toilet, the cleaning process of the device can be easily performed. Unlike the systems used according to the prior art, the flushing device (A) according to the present invention is not integral with the toilet, and it is a device installed on the product as a follow-on supplement and, if necessary, provides for removal for purposes of cleansing. Due to the advancement of water at the lateral edges of the toilet at different speeds due to the fact that the channels for the discharge of water have different diameters and emptied into the toilet from its lateral edge, the problem of spraying is also eliminated.
