Description

Instead of the name “system for preventing splashes and splashes for the toilet”, the phrase “system against splashes” can be used later in the text.

The invention relates to a plumbing device and equipment to meet the natural needs of a person * and can be used in household and public toilets to improve hygiene when using equipment.

* - the phrase "natural human needs" in the text of the description of this invention should be understood as organic waste of the body, liquid, intermediate, or solid type.

US Pat. No. 3,914,803 is known from the prior art, which describes a device that prevents splashing from a toilet bowl from liquid waste products of an organism and which is a curtain attached to a toilet seat that works when the seat is raised.

Differences from the declared solution are that:

- The anti-spray system is aimed at improving the hygiene status both in the case of liquid and in the case of solid waste;

- The anti-splash system does not involve fastening to the toilet seat;

- The anti-splash system protects from the spray not the surrounding space of the room, but directly to the toilet user.

The patent RU 149668 is known, which describes a plate mounted obliquely, which prevents the initial contact of feces with liquid. However, such a plate does not solve the problem of splashes from liquid waste products, in addition, the upper part of the plate is pivotally attached to the rear lower part of the seat, which can lead to contamination of the plate itself both from above and from the bottom of the plate, multiplication of microbes, drying of waste, and an unpleasant odor.

Differences from the declared solution are that:

- The anti-splash system is a device located almost completely in the water inside the drain hole, which prevents drying of the waste;

- The anti-spray system is a screener with a lattice structure that allows the reception of liquid waste, preventing them from splashing;

- The anti-splash system is completely washed with water when flushing the toilet bowl after use, which prevents its pollution and unpleasant odors.

Known patent RU 109390, describing a briquette of pressed sheet material, made with the possibility of expansion and the formation of a protective screen on the surface of the liquid receiving capacity of the toilet bowl.

Differences from the declared solution are that:

- The anti-splash system is constantly in the toilet drain and is reusable;

- The anti-splash system avoids splashing not only from solid waste, but also from liquid.

Known patent application RU 2011140811, describing a method of protection against spray by treating containers with a special solution using a device made in the form of a foam generator.

Differences from the declared solution are that:

- The system against splashes does not provide for the preliminary treatment of the toilet bowl, its drain hole or other parts;

- The anti-spray system is reusable and does not require adding to the tank, or the location of a separate container with a chemical solution, which must be constantly added or changed;

- The system against splashes is mechanical and does not require additional protection of the hands of maintenance personnel when washing or repairing plumbing equipment.

The closest solution is the patent application RU 2009103440, which describes a plate made of smooth and flexible plastic, characterized in that it is mounted directly above the toilet drain hole and when the water is drained in the toilet, the mudguard is pressed against the surface of the toilet bowl by the action of the mass of water flow, thereby repeating its contours and freeing the toilet drain hole for unimpeded drainage of water and the use of "brush".

Differences from the declared solution are that:

- The anti-spray system has a lattice structure, which allows to reduce the amount of spray from liquid waste, while the plate will be an obstacle to liquid waste and will lead to spraying;

- The anti-splash system is not mounted above the drain hole, but inside the drain hole at the water level, which prevents drying of adhering waste products and allows better washing of the toilet bowl and the system itself from contamination after using the toilet bowl.

In various situations, existing methods to prevent splashing in the toilet are ineffective. So, simply changing the shape of the toilet bowl or the location of the drain hole does not help get rid of the spray completely, because depending on the position of the user's body and the type of waste, the spray will be inevitable in one way or another. Chemicals that create a more viscous, including foamy, barrier to waste are effective only with a slight pressure of the liquid or low weight of solid waste. And the use of plates, guides and similar things is fraught with the accumulation of microorganisms in the places of their fastenings, the difficulty of cleaning them, drying of adhering dirt, as well as splashes from liquid waste products or from draining water, before the plates have had time to open the drain hole.

The technical result of the claimed invention consists in creating a toilet device that is either built-in or non-built, which is able to freely pass liquid through itself, prevents splashes from liquid waste and solid waste, is effectively washed by water, is able to open to pass solid waste, and has a design that prevents dirt from sticking .

The technical result is achieved by arranging the device in the toilet in the drain hole at the liquid level (which prevents dirt from sticking), using a screen having a lattice structure (freely passes liquid and improves washing of the bottom of the screen when draining water and prevents splashes) and is mounted inside the frame on axis with the possibility of rotation and return using a spring (for the passage of solid waste). Moreover, the device can work due to the elasticity of the spring and the weight of the waste and can not be built-in, or can be connected to the valve of the drain hole of the water from the tank and be built-in.

Particular cases of manufacturing a system for preventing splashes and splashes for the toilet are:

- Change the geometric shape of the device and the system as a whole;

- The location of the axis for opening the screen in the center or on one side, and the number of screens in this case can be one or more;

- The location of the device below or above the water level in the toilet drain;

- The use of hydraulic, pneumatic or electrical mechanisms as a screening drive;

- Transmission of the command to drive the screen using radio control;

- Another arrangement of the return spring.

Brief Description of the Drawings:

FIG. 2 - Screening device, top view;

FIG. 3 - Sectional screening device (section of a lattice structure);

FIG. 4 - Fragment of the installed system. Floating screening device in the toilet drain;

FIG. 5 - Fragment of the installed system in the open position.

The following elements are indicated on the images of the splash and splash prevention system for the toilet:

1. The body of the toilet;

2. Water tank;

3. Water;

4. The drive element of the screen from the tank valve, button, lever, etc. (may be absent);

5. The direction of discharge of water from the tank;

6. Screening device;

7. Screening frame;

8. The rotary shaft;

9. Return spring;

10. Holes of the screen;

11. Screening;

12. Air tanks (may be absent);

13. Drain button.

The toilet splash and splash prevention system works as follows:

When addressing the natural needs of a person in the form of liquid waste products, liquid flows from above onto the trellis screen (11), while the shape of the trellis screen (11) is such that the upper part of the grate has a thinning, or the grate is so narrow in itself that the liquid stream cannot encounter significant resistance to falling and splashing of liquid waste products in contact with the screen (11) does not occur.

In addition, since predominantly, the screen (11) is located so that its upper part protrudes slightly above the surface of the water (3) in the toilet drain hole, the part protruding above the water prevents strong spraying of waste and water in the event that a stream of liquid waste enters into the water through the hole of the screen (10).

When managing the natural needs of a person in the form of solid waste, the waste falls on the inner surface of the toilet bowl (1) and then, or immediately, on the upper surface of the screen (11). Further, if the system is not connected to other toilet systems, the screen (11), under the weight of solid waste, with the help of a rotary shaft (8) goes into the open position and solid waste enters the water (3). Then, the return spring (9) returns the rotary shaft (8) and the damper (11) connected to it to its original position. The dirt remaining on the screen (11) is washed off with water from the water tank (2) when the user activates the drain.

In addition to activating the rotation of the screen (11) from the severity of solid waste, it is also possible to use water pressure during discharge.

If the anti-splash system is connected to a drain button (13), a lever, a button, an electric motor or a valve located in the reservoir of the drive elements (4), then when solid waste enters the surface of the screen (11), the screen can continue to remain in the closed position until until the user, having completed the hygienic processes, presses, for example, the drain button (13) for water from the water tank (2). Together with the drainage of water, the rotary shaft (8) is activated by the drive element (4) and the screen (11) goes into the open position, passing solid waste into the water (3). In this case, the screening is returned to its initial position by means of a spring (9) when the force of action of the drive element (4) on the rotary shaft (8) decreases.

Features of the invention:

1. Similarly, as described above, the anti-splash system works with intermediate-type waste of various densities, as well as kitchen waste. For example, if a soured soup is poured into the toilet, then the system prevents the release of unpleasant splashes that can get on clothes, a person’s body or other objects. In this case, the liquid immediately enters the water (3), and the passage of solid waste from the kitchen is initiated by one of the above methods.

2. The device and the system as a whole can have a built-in and non-built-in type. If the system is built-in type, then there may be no cage (7) and there is a drive element (4), and there may also be elements for installing the system on a specific toilet model. On a non-built-in type of system, there is a frame (7) and no drive element (4), there are no special elements for installation. The non-built-in type is more versatile, it can be used on several toilet models, provided that the drain hole is the same, and is not connected to other toilet systems.

3. The most convenient location of the system - the system is almost completely immersed in water, above the surface of the water is only a small part of less than 25% of the vertical size of the device. In this case, the claimed technical result is achieved in the best way.

But subject to the use of other, additional, systems, as well as a certain shape of the toilet, the system may be located completely above the surface of the water, or completely in the water.

4. Considering that, depending on the type of toilet bowl or type of sewage system, the water level (3) in the drain hole of the toilet bowl may differ in different cases, then to achieve the most optimal location of the barrier (11) relative to the water level (3), a control system can be applied location of the screen.

This system consists in the manufacture of system elements from floating materials either located inside the frame (7) (if the frame is movable), or inside the screen (11) of the air tanks (12), which allow the device to be held at the required level relative to the water surface (3).

But it is worth paying attention that such a system will retain mobility and when using the toilet and, for example, from solid waste, the device may slightly shift, for example, the horizontal arrangement of the device will be lost.

5. Depending on how the rotation of the screen (11) is activated and the system is activated, the elasticity of the return spring (9) also varies. So, if the system is activated from the severity of solid waste or from the pressure of water from the tank (2), the spring (9) must have the least elasticity so that the screen can open effectively. If the system is activated through the drive element (4), then the spring force (9) must be higher in order to keep the screen in the closed position until the user engages the drain.

In this case, it is possible to use a compression, tension, torsion spring (shown schematically).

6. The rotary shaft (8) is mainly located at the front wall of the drain hole, since in this case the screen (11) is best rinsed with water pressure when draining.

But it is possible to locate the rotary shaft at the rear or side wall of the drain hole, depending on the shape of the drain hole, the design of the toilet bowl and the direction of water flow (5).

The location of the rotary shaft in the middle is acceptable, but ineffective, since in this case the rotary shaft (8) will create a natural obstacle to the movement of solid waste into the drain hole.

7. The shutter (11) can be actuated using the mechanical element of the drive (4), as well as using a hydraulic or pneumatic system that will cause the shaft (8) to rotate, using an electric drive that will rotate the rotary shaft (8). Moreover, the use of a mechanical drive and an electric drive is most relevant, since a mechanical drive should not create additional difficulties in the manufacture of a toilet bowl (1), and an electric drive will be relevant in public toilets when the toilet is drained using a photocell and other electromechanisms.
