Description

The invention relates to reducing acoustic noise generated in the toilet when the cistern is filled with water.

Everyone knows that when the water is lowered 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 flushing cistern (rather long and noisy). The prior art patent RU 2175044, publ .: 10/20/2001., Based on the task of creating a device that would improve the working conditions of the flush tank, reduce acoustic noise from moving water and prevent it from splashing when filling the flush tank. The decision was made as a prototype.

The prototype describes a valve for associated pressure, comprising a housing equipped with a bracket, a rod with a labyrinth seal, a through hole and a locking element, a feed nozzle, a gasket with a central hole, a float with one hole at the bottom and two coaxial holes on it side surfaces, placed on the lever, pivotally connected to the rod, a small lever lever is installed through a hole made in the housing, and a through hole made in the stem, and a hinge It is fixed in the bracket, characterized in that the bracket is made with a deaf mounting groove, the said hole in the housing is made longitudinal in the lower part of the housing, and the small lever arm 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. Installing such a valve inside the flush tank may be impossible or extremely difficult due to the lack of free space for a non-standard system.

In addition, the gasket quickly accumulates plaque at the time of non-use of the toilet bowl and the locking element begins to loosely adhere to it, which causes leakage.

Also, the valve does not have the possibility of adjustment for the purpose of quick water intake, when the noise does not create interference (for example, during the day) and the water is always collected slowly. During the operation of the toilet, it is sometimes necessary to wash it again, but the slow filling of the tank will not allow it to be done quickly. As a result, you have to wait until the tank is full.

The purpose of this solution is to eliminate the obvious drawbacks of the prototype.

The technical result is the reduction of acoustic noise from filling the cistern with the lower water supply, versatility (the ability to use on any toilet toilets with the lower water supply having any lever-float system), as well as the ability to work in two modes: fast (normal) filling with noise , or slow filling, but without noise.

This technical result is achieved due to the fact that the claimed method of reducing acoustic noise when filling the cistern of the toilet bowl with the lower water supply, characterized by using valve associated pressure, comprising a housing, in the cavity of which is a seal with a through hole and a locking element, the hole in the housing longitudinal, characterized in that the valve is installed in the outer zone of the toilet bowl between the end of the water supply hose to the toilet bowl and the tank filling valve and is performed i in such a way that the inside of the valve body is formed from a cylinder with a constriction, the narrow part of which passes into a tube whose diameter is less than half the internal diameter of the cylinder, and inside the valve body is placed a freely moving shut-off element in the form of a ball made of ferromagnetic metal, which is covered plastic and perform rough, and the diameter of the ball perform more than the diameter of the inlet, where the taper goes into the tube; in the area of the tube, a ring in the form of a ferromagnet metal washer is inserted into the valve body, and a plastic-coated magnet ring is put on the cylinder, the inner diameter of the magnetic ring being larger than the diameter of the cylinder and so that the magnetic ring slides freely on the outer surface cylinder.

Preferably, in the zone from the beginning of the constriction to the transition of the constriction into the tube, the inner surface of the body of the body is made up of vertical cavities open to meet the flow of water.

Preferably, a liner is placed inside the cylinder on the bottom side, which is formed as a surface of a cone without a base and having symmetrically arranged openings along the surface.

Preferably, an additional lever mechanism is used to control the magnetic ring by mechanical crimping or incorporating one or more magnets.

The implementation of the invention

The method can be implemented by forming a device (see Fig. 1) of a valve, the body 1 of which is formed in the form of 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 place of installation - under the cistern, which is a fairly convenient place for the hand sitting on the toilet.

At the point of transition of the nut 7 into the cylinder, a ring in the form of a metal washer is soldered into the plastic. If necessary, it can be made slightly larger than the nut 7. The metal used must have ferromagnetic properties (well magnetised), but must not be a magnet. On the cylinder dressed 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 causes 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, then the magnetic ring 3 can be freely removed from the bottom side of the cylinder). The inner surface of the cylinder has a narrowing 9, for example, of a conical shape, starting from about half a cylinder, the upper (narrow) part of which passes into the tube 10 and with a diameter slightly less than half the internal 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 resulting constriction 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 pad is used as a support for the rubber gasket between the device and the filling valve (when installed, the device is screwed onto the filling valve until the valve stops in the platform). At the bottom of the cylinder has a diameter larger than the main part of the cylinder. This expansion serves as a landing place for the jet breaker 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 have a cone in the direction of water flow, and a ball 4 with a diameter of about a little more, than the diameter of the hole in the constriction of the cylinder, but large enough so as not to get stuck in the constriction opening The ball 4 is made of ferromagnetic metal (metal with good magnetic properties), but not a magnet, it is coated with plastic and has a rough surface.

This device also reduces the hydraulic shock, loosening the hydraulic system and occurring during operation (upstream) of the filling valve. To remove water hammer with high water pressure, in the zone from the beginning of the restriction to the transition of the restriction into the tube, the inner surface may contain cavities 6, made in the body of the valve body in the direction of water flow. Cavity 6 removes the kinetic component of the impact. During operation, the cavities 6 are filled with gas released from the water during operation and serve as a pressure compensator.

The principle of installation of the valve to reduce acoustic noise on the toilet consists of the following.

Close the water supply valve for filling the toilet bowl. Turn off the water supply hose to the tank from the valve filling the toilet bowl. Insert the rubber gasket into the device case from the side with internal thread (where the nut is 7). The valve is screwed to reduce acoustic noise to the water supply valve in the tank. Magnetic ring 3 is worn, magnetic to the protrusion under nut 7, which is formed by a soldered ring in the form of a washer 5 from a metal of a ferromagnet.

Then insert the ball 4 and, if necessary, the insert 2, screw the supply hose to the device. After that, the device is ready for operation.

Under some operating conditions, when the components of the water supply system are colder than the dew point, moisture may form at the valve installation site, 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), controlling the valve using magnetic elements 13, has a small shoulder 14 connected to a large shoulder 12 by means of a swivel 15. The shoulder 12 has a hole in the middle, which is mounted on the body behind the magnetic ring. Under the action of magnets 13, the tight contact of the shoulder 12 of the lever mechanism and the magnetic ring 3, which is driven by the large shoulder 12, is fixed.

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

The principle of operation of the valve to reduce acoustic noise is as follows. Mode 1.

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

Mode 2.

The magnetic ring is raised by the fingers and is magnetic to the ledge (soldered ring) in the upper part of the device. The ball, lifted by a magnetic ring, closes the conical hole in the upper part of the device. The seeping water does not create pressure causing noisy filling (longer, but silently). This mode is useful when silence is required in the room (for example, at night). Technically, it is possible to switch from mode 1 to mode 2 automatically or by timer using additional devices that are not protected by this solution.

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