Description

A Toilet Waste Water Drain Structure that Saves Water by Eliminating the

Requirement for a Reservoir

Technical Field

The invention is related to a toilet waste water drain structure, which has a cover mechanism which provides water saving, ease of installation and one hundred percent efficiency by eliminating the requirement of a clean water tank (reservoir) as in existing toilet system for use in sanitary ware industry in general.

Prior Art

The British-type float method is used in state of the art systems today. The system in question attempts to remove the waste and to ensure that clean water remains in the toilet by means of a reservoir in which a float is activated and the water in the reservoir is discharged into the toilet through water outlet channels. However, since the amount of water required to ensure the removal of waste water always has to be more than the waste water, the achieved water saving efficiency with this technique is low.

Among the current applications, the products with lowest water savings use the water actually needed for cleaning and more for waste disposal purposes, and thus the water consumption amounts are very high.

In the state of the art, since waste disposal is realized with high amounts of water, a reservoir is required. When this reservoir is located over the toilet, hung to the wall, it makes impossible to achieve space and water savings. In order to save space, in wall- recessed systems, in addition to the labor and cost required during the first installation, in case of a reservoir leak or when the float in the reservoir malfunctions, the wall in question should be demolished and the reservoir should be removed and after the service, the wall should palstered and tiled again. Therefore, the system in question is costly when there is a fault, requires a high level of labor and it is difficult to apply to an old building.

Another element in the state of the art is efficiency. Since the discharge of waste water is realized with water, it is not possible to perform one hundred percent efficiently in the discharge of waste which is difficult to sink in the water due to the fact that the waste is lighter than water or larger. In the state of the art, a steam generator is used instead of the water tank in question in another system and the drain in the toilet is cleaned with less water. In other words, cleaning is executed by means of steam. However, the mentioned system is a costly and difficult to maintain and repair and it is ineffective in case of a power failure, so the small amount of water is not enough to discharge the waste water from the toilet.

Problems with existing applications are as follows; existing fixed float systems experience blockages of S pipe under the toilet seat. As the waste that tries to pass through the last peak point, it is exposed to surface friction, slows down and blockages are encountered as a result of stucking and staying there. Vermins such as rats etc. may crawl through the S pipe which has an exposed end. Since a reservoir is used, it is not suitable for saving water. They are not entirely efficient at waste disposal.

The patent application no. TR2009/07979 encountered in the patent survey in the previous technique is related to a toilet that does not require a fixed S pipe at the bowl outlet, where the bowl outlet and the sewage pipe is connected by means of a waste discharge pipe made of elastic material such as silicon or rubber. This hose is humped by pulling up with springs associated with the hanger of the waste drain hose, and flattened by the lever attached to a foot pedal. When the waste drain hose is placed in the flat position, it will be possible to drain the waste into the city sewer with very little water, as it does not meet a fixed threshold at the outlet of the bowl. This water saving feature is related to a water saving toilet bowl which does not require a reservoir.

As a result, improvements are being made in the toilet waste water drain structure, so new structures are needed that will eliminate the disadvantages mentioned above and provide solutions for existing systems.

In Figure-1 and Figure-2, perspective views of the cross-section of the toilet waste water drain structure (100) is illustrated in closed and open states. Invention allows preventing water losses by providing maximum cleaning with minimum water without the need for a reservoir by means of a cover system.

Figure-3; shows a perspective view of the some parts of the toilet waste water drain structure of the invention, Figure-4; shows a perspective view of the some parts of the toilet waste water drain structure of the invention in the open state, Figure-5; shows a perspective view of the some parts of the toilet waste water drain structure of the invention in the closed state. The invention is intended to be used in sanitary ware industry to provide water savings by eliminating the need for a reservoir. There is a toilet on which the user sits and a clean water inlet through which clean water enters the mentioned toilet. There is a waste storage chamber (108) which is the area where clean water and contaminated water are stored where people make their feces.

A cover (102) which is connected into the toilet to form the drain part and which allows the contaminated water to be disposed outside bye opening is provided. A fastener (102.2) selected as the shaft that enables the movement of the mentioned cover (102) in the toilet is provided. A drive element (104.5) which provide the necessary drive for the movement of the mentioned cover (102) is provided. A drive train element (104.1 ), preferably selected as a drive shaft, which allows the cover (102) to open and remain fixed at the closed state by means of the drive delivered from the drive element (104.5) is provided. The mentioned drive train element (104.1 ) is in T form. In order to allow the drive transfer element (104.1 ) transfer the drive from the drive element (104.5) to the cover (102), there is a power train house (102.3) that allows the drive transfer element (104.1 ) to be seated into the cover (102). Once the cover (102) is opened at the desired level, the feedback element (104.2) allows the drive element (104.5) to move the cover (102) in the direction of closure. A feedback switch is selected as the feedback element (104.2). There is a protrusion (102.21 ) on the connector (102.2), which allows the drive element (104.5) to determine the direction of operation by placing the feedback element (104.2) in an open or closed position.

A powertrain spring (104.4) which allows the drive element (104.5) to apply controlled and increased power to the cover (102) is provided. When the drive element (104.5), which is in freely oscillating state rotating towards the closing direction, contacts onto the sealing element (107) of the cover (102), the powertrain spring (104.4), with the drive train element (104.1 ) rotating counterclockwise, i.e. towards the spring (104.4), establish an abutment and exert a power to the cover (102) proportional to the properties of the spring (104.4). The compression element (104.3) determines the level of pressure applied by the drive element (104.5) to the powertrain spring (104.4). A compression switch is preferred as the compression element (104.3).

A level control element (103) which controls the level of the water filled into the toilet

(101 ), preferably a float, is provided. The electronic circuit (105) allows the timing of opening and closing of the cover (102) and other parts of the system. A control element (106) provides control of the water to flow into and out of the toilet (101 ). The mentioned control element (106) is preferably a solenoid valve. A power supply (1 10) that provides the necessary power for operation is provided. The system has the starting element (109), preferably a button, which is used to start and run it. Where excess water flows into the cover (102) through the clean water inlet (101.1 ), there is an excess water outlet (102.1 ) that opens onto the lid (102) to ensure that the excess is flowing out and that the water in the toilet (101 ) remains at a certain level. The drive element (104.5), the compression element (104.3) and the feedback element (104.2) are equipped with the drive element jacket (104) which provide protection against external factors. There are preferably two bearings (104.51 ) that allow the drive train element (104.1 ) to be seated on the drive element jacket (104). The cover (102) has a sealant (107) which applies pressure on the cover (102) to prevent water from flowing when the cover is closed and which is selected from materials such as sponge, plastic and rubber. When the electricity feeding the system is cut, infinite screw system (104.52) ensures that the system stays in the vacuum state by using the drive element (104.5) inside the shaft system in order to prevent the drive element (104.5) to return back with the force exerted by the spring (104.4).

Figure-1 1 and Figure 13 show perspective views of cross sections of the cover (102) with different cover design of the toilet waste water drain structure (100) of the invention in closed state, Figure-12 shows another perspective views of cross section of the cover

(102) of the toilet waste water drain structure (100) of the invention in closed state, Figure- 12 shows another perspective views of cross section of the toilet waste water drain structure (100) of the invention in open state.

The operating logic of the waste water drain structure (100) of the invention is as follows; In the normally closed NC state as shown in Figure-6 and Figure-7; this is the position where the waste filling chamber (108) is filled with clean water or waste, the cover (102) is closed, ready for isolating or discharge. Feedback element (104.2) is in open NO position, compression element (104.3) is in closed NC position, powertrain spring (104.4) is compressed and in powertrain position, drive element (104.5) is locked by means of the infinite screw gear system (104.52) and is fixed in closed NC position.

In the natural, oscillating, free N position shown in Figure-8 and Figure-9, in this position the cover (102) is in free motion within the vacuum channel (104.6).

In the normally open NO position Shown in Figure-10; in this position the cover (102) is open, where the waste is discharged and the cleaning/filling water system is open.

In order to start the system when the waste filling chamber (108) is full and the system is in the closed NC state as seen in the Figure-6, when the starter element (109) is pressed, a 12 V voltage supplied by the power supply (1 10) rotates the drive element (104.5) counterclockwise, with the drive element (104.5) itself rotating in the clockwise direction, the compression element (104.3) and the powertrain spring (104.4) return to their natural, oscillating, free N state. The drive train element (104.1 ) rotating inside two concentric bearings (104.51 ), one of which is mounted on the body while the other is mounted on the drive element jacket (104), brings the cover to the natural state from the vacuum state, when the connector (102.2) fixed onto the cover (102) provides motion for the cover (102), which is in natural, released, free N2 state within the limits of the vacuum channel (104.6), towards the opening direction. In this case, the waste discharge begins and the level control element (103), preferably a water-powered electronic float in the waste filling chamber (108) detects that the water level has dropped and starts the solenoid valve with the control element (106). The control element (106) allows water to flow through the clean water inlet (101.1 ). When the hatch (102) that continues to open and reaches its open position in the normally open NO as shown in Figure-10, the discharge is complete and the connector (102.2) on the protrusion (102.21 ) moves the feedback element (104.2) to the normally closed NC position, allowing the drive element (104.5) to rotate clockwise. The cover (102), which rotates towards the closing direction, comes to the vacuum position. Drive element (104.5) in free oscillating motion, which rotate the shaft which increase the force exerted on the cover (102) which start applying pressure onto the sealing element (107), as reaction in response this action (i.e. until it finds an abutment point), starts rotating about the shaft's axis counterclockwise and, compresses the powertrain spring (104.4) and the electric current supplied to the drive element (104.5) is cut off when the compressing element (104.3), whose distance to the peak point of the spring (104.4) parallel to the central axis of the spring is adjustable, is brought to the NC position and at this moment, when the drive element (104.5) ensures that the cover (102) is closed and isolated using the infinite screw thread system (104.52) inside the shaft system of the drive element (104.5) using the spring (104.4) force, the level control element (103) which stars moving with the increasing water level inside the waste filling chamber (108) closes the solenoid valve and cuts off the water flow and returns into the standby state in order to be started again when the starting element (109) is pressed again.
