Description

The utility model relates to a means of reducing the level of acoustic noise that occurs in a toilet bowl when filling a flush cistern with water.

Everyone knows that when flushing water in the toilet, a not very pleasant sound appears, consisting of two components - the sound of merging water (short-term) and the sound of a filling flush tank (quite long and noisy).

The patent RU 2175044, publ.: 20.10.2001., Based on the task of creating a device that would improve the working conditions of the flush tank, reduce the acoustic noise from moving water and prevent its splashing when filling the flush tank, is known from the prior art. The decision was made as a prototype.

The prototype describes a valve with associated pressure, comprising a housing equipped with a bracket; a rod with a labyrinth seal, a through hole and a locking element, a supply pipe, a gasket with a central hole, a float with one hole in the bottom and two coaxial holes on it are installed in the body cavity side surfaces, mounted on the lever, pivotally connected to the rod, a small lever arm is installed through an opening made in the housing, and a through hole made in the rod, and the hinge o fixed in the bracket, characterized in that the bracket is made with a blind mounting groove, the specified hole in the housing is made longitudinal in the lower part of the housing, and the small arm of the lever has a flat biconvex shape in the middle part between the attachment point to the bracket and the bend.

The technical problem of this valve is the need to install it inside the tank on the lever-float system. This causes difficulties when it is necessary to install such a valve inside the toilet bowl, where installation of an additional element of other sizes may be impossible or extremely difficult. In addition, the gasket quickly picks up plaque when the toilet is not in use and the locking element begins to snugly against it, which causes a leak.

Also, the valve does not have the ability to adjust for the rapid collection of water, when the noise does not interfere (for example, during the day) and water is always typed slowly. When using the toilet, this sometimes creates difficulties when a second flush is required, but the tank has not yet been filled with water. As a result, it will take a long time to wait for the water to pour.

The objective of this solution is to eliminate the obvious disadvantages of the prototype.

The technical result is the reduction of acoustic noise from filling the flushing tank with a lower water supply, versatility (the ability to use on any toilet with a lower water supply, having any lever-float system), as well as the ability to work in two modes: fast filling, but with noise or slow filling but no noise.

The specified technical result is achieved due to the fact that the claimed device for reducing acoustic noise from filling the flush toilet bowl with a lower water supply, comprising a housing in the cavity of which a seal is installed with a through hole and a locking element, the hole in the housing is made longitudinal, characterized in that the inner part of the valve body is made in the form of a cylinder with a narrowing, the narrow part of which passes into a tube whose diameter is less than half the inner diameter of the cylinder, and inside the valve a freely moving locking element is located in the form of a ball made of ferromagnet metal, which is coated with plastic and roughened, moreover, the diameter of the ball is larger than the diameter of the inlet where the restriction passes into the tube, and the tube has an exit to the nut having an internal thread for screwing onto the filling valve a tank, and the nut is part of the housing; in the zone where the tube is located, a ring in the form of a washer made of a ferromagnet metal is soldered into the valve body, and a ring of a magnet coated with plastic is put on top of the cylinder, and the inner diameter of the magnetic ring is slightly larger than the diameter of the cylinder.

Preferably, in the area from the beginning of the constriction to the transition of the constriction into the tube, the inner surface comprises cavities made in the body of the valve body, open towards the movement of the water flow.

Preferably, a liner is installed inside the cylinder from the bottom side, which is the surface of the cone without a base, having symmetrically located openings on the surface.

Preferably, a lever mechanism with a handle is additionally mounted connected to the magnetic ring by mechanical crimping or by magnets.

Utility Model Implementation

The device (see Fig. 1) is made in the form of a housing 1, which is a plastic cylinder. The upper part of the cylinder is a nut 7 (integral with the cylinder), screwed onto the tank filling valve (on the outside of the tank). The lower part 8 has an external thread on which a water supply hose is screwed. This determines the installation location - under the tank, which is a fairly convenient place for the hand of a person sitting on the toilet.

A ring in the form of a metal washer 5 is soldered at the point where the nut 7 moves into the cylinder into the plastic. If necessary, it can be made slightly larger in diameter than the nut 7. The metal used must have ferromagnetic properties (magnetize well), but should not be a magnet. The cylinder is wearing a magnetic ring 3 (magnet), covered with plastic. The inner diameter of the magnetic ring 3 is slightly larger than the diameter of the cylinder, which leads to the free movement of the magnetic ring 3 from the washer under the nut 7 to the nut of the supply hose (if the device is not installed, the magnetic ring 3 is freely removed from the bottom of the cylinder).

The inner surface of the cylinder has a narrowing 9, for example, of a conical shape, starting from about half of the cylinder, the upper (narrow) part of which passes into the tube 10 and with a diameter slightly smaller than half the inner diameter of the cylinder. The tube 10 ends at the level of the washer 5, located under the nut 7. The upper part of the constriction formed is a flat area perpendicular to the axis of the inner surface of the cylinder, with a round hole in the middle. During installation, this platform is used as a support for a rubber gasket between the device and the filling valve (during installation, the device is screwed onto the filling valve until the valve stops in the platform). In the lower part, the cylinder has a diameter larger than the main part of the cylinder. This expansion serves as a seat for the jet-splitting liner 2, if required (usually with high water pressure).

The liner (see Fig. 2) can be made, for example, in the form of a cone without a base with side holes 11. Between the cone of the liner 2, which has a cone in the direction of movement of the water flow, and the narrowing in the cylinder is a ball 4 with a diameter of about slightly more, than the diameter of the hole in the narrowing of the cylinder, but large enough not to get stuck in the narrowing hole. Ball 4 is made of ferromagnet metal (metal with good magnetic properties), but not a magnet, covered with plastic and has a rough surface.

This device also reduces the water hammer that shakes the hydraulic system and occurs during operation (upstream) of the filling valve. To remove water hammer at high water pressure, in the area from the beginning of the narrowing to the transition of the narrowing into the tube, the inner surface may contain cavities 6 made in the body of the valve body in the direction of movement of the water flow. Cavity 6 removes the kinetic component of the impact. In the process, the cavities 6 are filled with gas released from the water during operation, and serve as a pressure compensator.

The principle of installing a valve to reduce acoustic noise on the toilet is as follows.

Close the water tap to fill the toilet bowl. Unscrew the water supply hose to the tank from the filling valve of the toilet bowl. Insert the rubber gasket into the device body from the side with internal thread (where nut 7). Screw the valve to reduce acoustic noise to the valve supplying water to the tank. The magnetic ring 3 is dressed up, magnetizing it to the protrusion under the nut 7, which is formed by a soldered ring in the form of a washer 5 made of a ferromagnet metal.

Then insert the ball 4 and, if necessary, the liner 2, screw the feed hose to the device. Then the device is ready to work.

Under certain operating conditions, when the components of the water supply system are colder than the dew point, moisture may form in the valve installation location, and the magnetic ring 3, although covered with plastic, will not be very pleasant to the touch. To eliminate this problem in case of its occurrence, as well as in order to increase comfort, it is possible to use a lever mechanism that controls the magnetic ring by mechanical crimping (see Fig. 4) or includes a magnetic element (see Fig. 3).

The lever mechanism (see Fig. 3), which controls the valve using magnetic elements 13, has a small arm 14 connected to the large arm 12 via a swivel joint 15. The arm 12 has a hole in the middle that fits onto the housing behind the magnetic ring. Under the action of magnets 13, a tight contact of the shoulder 12 of the lever mechanism and the magnetic ring 3 is fixed, which is driven by the large shoulder 12.

To install the lever mechanism (see Fig. 4), you first need to screw a plastic nut (stopper) onto the filling valve stem, then put a small lever arm 14 on the rod with a specially made hole 16 and then screw a valve on the rod with the large lever arm dressed on it 12 through another special hole 17 is already in the large lever, while the free end of the lever 12 serves as a valve control handle.

The principle of operation of the valve to reduce acoustic noise is as follows.

Mode 1.

The magnetic ring is located on the nut of the supply hose (at the bottom of the device), filling occurs as usual - quickly and noisily. This mode is advisable when you need to quickly draw water into the tank for re-flushing and you can make noise (for example, during the day).

Mode 2.

The magnetic ring is lifted by the fingers and magnetized to the protrusion (soldered ring) in the upper part of the device. A ball raised by a magnetic ring plugs a conical hole in the upper part of the device. Leaking water does not create pressure causing noisy filling (longer, but noiseless). This mode is useful when you want to keep silence in the room (for example, at night). It is technically possible to switch from mode 1 to mode 2 automatically or by timer using additional devices that are not the subject of protection for this solution.

Thus, the valve according to the claimed solution provides a reduction in acoustic noise from filling the flushing tank with a lower water supply, it can be installed on any toilet with a lower water supply, having any lever-float system. In addition, the claimed solution allows the valve to be used in two modes: fast filling, but with noise or slow filling, but without noise.
