[0001] STRUCTURE ENABLING TO ADJUST THE FLOW OF WATER TO BE TRANSFERRED FROM FLUSH TANK INTO CERAMIC SANITARY WARE

[0002] Subject of the Invention

[0003] The invention relates to a structure, which enables to adjust the flow of the water transferred from a flush tank into a ceramic sanitary ware in order to flush said ceramic sanitary ware.

[0004] State of the Art

[0005] It is required to flush the ceramic sanitary ware, especially the toilets and the squatting toilets, after the use. For this purpose, the water is commonly accumulated in a flush tank or in similar structures and the flushing process is realized upon the discharge of said water into the ceramic sanitary ware as a result of the flushing system being triggered. The conventional toilets had a flushing channel wherein the water transferred from the flush tank filled into said channel and was distributed into the toilet bowl via the holes on said channel. However, due to some hygiene problems caused by the toilets with channel, the difficulty in flushing the toilets with channel, the loud noise generated during the flushing, and the similar reasons, the toilets with channel have today been replaced by the toilets with no channel that do not have any channel. In the toilets with no channel, the water coming from the flush tank is distributed into the toilet bowl preferably by means of a distributor apparatus. Here, what is important is to ensure that the water reaches every point of the toilet and provides an effective flushing, while causing no splash from the toilet bowl. Therefore, it is necessary to adjust the flow of the water to be transferred from the flush tank into the toilet, according to the type of the flush tank and / or the toilet being used. This adjustment may be achieved through the use of different parts according to the type of the toilet and / or the flush tank. However, the preferred embodiment is a structure, which has a construction enabling the flow to be adjusted via a single part without using different parts and which is thus able to be adapted according to the type of the toilet and / or the flush tank. As a result, the same structure, owing to the ability of adjustment, is able to be used with more than one flush tank and / or toilet type.

[0006] EP3138969B1 discloses a drainage valve enabling the flush flow to be limited. The valve system disclosed in said document comprises a flow limiting member wherein the water to be transferred from a flush tank into a toilet is enabled to be adjusted depending on the position of said member on the spacer parts. Said solution has a first locking member and a second locking member, which enable the position of the limiting member on the spacer parts to be adjusted. As a result of the limiting member being rotated in one direction, the second locking member becomes released from the first locking member and the flow limiting member is thus able to freely move in the downward or upward direction. After the flow limiting member is brought into the desired height, said flow limiting member is rotated in the reverse direction and the second locking member gets in the first locking member, and thus, the position of the flow limiting member is fixed. One of the biggest disadvantages of said system is that it is not possible to fix the flow limiting member at any desired position. More particularly, the flow limiting member may be fixed in a stepwise manner only at the positions of the first locking member, which in turn adversely affects the precision of the adjustment. In other words, even though the flow is adjustable in said system, the adjustment without any limitation is not possible and it is only allowed to make a selection from among the predetermined steps. Another disadvantage of said solution involves some problems of durability caused by the locking system present in said solution. The reason is that the limiting member has a U-shaped slot and groove in order for said locking systems to be able to function wherein the respective portion is conferred a flexible character owing to said slot and groove and the respective portion is thus enabled to realize the entry to and exit from the first locking member. However, said movement is a disadvantage that could cause the deformation of the respective part and thus the fracture of the same in the course of time.

[0007] EP32O8393B1 similarly discloses a structure enabling the flush flow to be limited. Said system has a limiting member, which enables to limit the water transferred from a flush tank into a toilet. Said limiting member, as a result of being rotated, changes the surface area of the cross-section of the flush tank that opens into the toilet and thus enables the water flow to be limited. The butterfly structure present in said system may disturb the flow characteristic. Moreover, that it is not possible to access said butterfly structure after the mounting and that it is therefore not possible to adjust the water flow after the mounting are among the other existing disadvantages of said system.

[0008] Object of the Invention

[0009] An object of the invention is to develop a structure, which enables to adjust the flow of the water transferred from a flush tank into a ceramic sanitary ware in order to flush said ceramic sanitary ware.

[0010] Another object of the invention is to develop a structure, which enables to adjust the flow of the water to be transferred from a flush tank into a ceramic sanitary ware according to the type of the flush tank and / or the toilet.

[0011] Another object of the invention is to develop a structure, which permits the adjustment of the flow of the water to be transferred from a flush tank into a ceramic sanitary ware in accordance with the preferences and the needs, without any step being present.

[0012] Another object of the invention is to develop a structure, which enables to adjust the flow of the water upon a change in the surface area of the opening where the flow takes place from the flush tank into the toilet, said change being dependent on the movement of the movable component said system comprises.

[0013] Another object of the invention is to develop a structure without any locking mechanism wherein the change is enabled in the area of the opening where the flow takes place depending on the helical movement of the parts on one another.

[0045] In a preferred embodiment of the invention, the water flow opening (14) is a water flow opening (14), which extends in a direction opposite to the direction of the gravity force, i.e., which extends upwards from the bottom of the flush tank.

[0046] In a preferred embodiment of the invention, the body (1) has at least one water channel (13), which enables the water passing through the water flow opening (14) of said body (1) to be delivered into the toilet. Said water channel (13) is a water channel (13), which enables the delivery of the water to the opening that permits the passage of water from the flush tank into the toilet.

[0047] In a preferred embodiment of the invention, the water flow opening (14) is a water flow opening (14), through which the water inside the flush tank passes to reach the interior of the body (1) and is subsequently transferred into the toilet by means of the water channel (13).

[0048] In a preferred embodiment of the invention, the body (1) has at least one valve extension gap (17), through which the valve extension (VU) may pass and inside which the valve extension (VU) may freely move in the direction of the gravity force or in the opposite direction and may thus close or open the opening that permits the passage of water from the flush tank into the toilet.

[0049] In a preferred embodiment of the invention, the water flow opening (14) is a water flow opening (14), wherein the area of the surface of said water flow opening (14) where said water flow opening (14) permits the passage of the water inside the flush tank changes depending on the movement, i.e., the position, of the adjustment member (2). The water flow opening (14) is a water flow opening (14), which, as a result of the area of the surface where said water flow opening (14) permits the passage of the water being changed, enables the adjustment of at least one variable of the water to be delivered to the opening that permits the water passage from the flush tank to the water channel (13) and / or into the body (1) and / or from the flush tank into the toilet. In a preferred embodiment of the invention, the water variables, which are adjusted upon the area of the surface of said water flow opening (14) where said water flow opening (14) permits the passage of the water inside the flush tank being changed as a result of the movement of the adjustment member (2), include but are not limited to the velocity and / or flow rate and / or flushing force and / or flushing action of the water.

[0050] In a preferred embodiment of the invention, the adjustment member (2) is an adjustment member (2), which, by moving on the body (1), enables the area of the surface of the water flow opening (14) where said water flow opening (14) permits the passage of the water to be changed. In a preferred embodiment of the invention, the adjustment member (2) is an adjustment member (2), which moves on the body (1) in the direction of the gravity or in the opposite direction. In a preferred embodiment of the invention, the adjustment member (2) is an adjustment member (2), which moves in the direction of the gravity or in the opposite direction as a result of being rotated on the body (1).

[0051] In a preferred embodiment of the invention, the body (1) has at least one adjustment member bearing (15), on which the adjustment member (2) is to move. In said embodiment, the adjustment member (2) has at least one adjustment member pin (21), which is to move inside said adjustment member bearing (15). Said adjustment member pin (21) is an adjustment member pin (21), which, by moving inside the adjustment member bearing (15), enables the adjustment member (2) to move on the body (1) only along the adjustment member bearing (15). Similarly, the adjustment member bearing (15) is an adjustment member bearing (15), inside which the adjustment member pin (21) moves and which enables the adjustment member (2) to move on the body (1) only along said adjustment member bearing (15).
