Abstract

The invention relates to toilet facilities, to structural design for domestic and, for example, railway car WC bowls and to WC flushing cisterns thereof. Said invention makes it possible to enhance flushing efficiency of a portion of water having an increased pressure at the beginning of each flushing cycle. The inventive WC flushing cistern is based on the formation of an 'air dome' in a sealed cistern body, to which water is supplied from the bottom, from a water supply system or from a tank arranged above the car ceiling. In addition, in one of the variants, the flushing cistern is provided with two reservoirs, thereby making it possible to vary a flushing process, for example by using two manifolds in the bowl, and to save water by removing an overflow passage from the cistern.

Description

Flush toilet bowl

The invention relates to sanitary - hygienic equipment, to flush toilet tanks intended for accumulating a certain portion of tap water to flush the toilet. From the patent literature a flushing tank is known, for example, according to the application RU 2003116683 A. E 03 D 1/24; or according to patent RU 45742 Ul E 030 D 1/24 of the same author S.I. Sherstyannikov, which consists of a body, a cover, a shelf, a drain valve, an inlet valve, a float, a saddle with a shut-off valve mounted on an overflow pipe on which it is mounted also a water start button.

Flushing cisterns, raised to a height of approximately human height above the toilets and connected to the last water pipes of a considerable diameter, equipped with start buttons in the form of corresponding extension cords, for example, in the form of metal chains with handles, are also widely known in practice.

The disadvantages of the known flushing cisterns are that the water drained from them enters the collector of the toilet flush system under slight pressure, due to the height of the raised cistern above the toilet, or, as in the latter case, the metal structure and the complexity of its maintenance.

According to patent RU 45695 Ul B 61 D 35/00, the “Flush water dispenser for unit" is known, which contains a housing, a cover, a flexible diaphragm sandwiched between them, a check valve, and pressure and discharge cavities are formed in the dispenser with a diaphragm, and a metering stop mounted in the housing limits the diaphragm stroke, which occurs under the influence of the working medium from a pressure source. Such a flushing tank, when turned on, sends water to the toilet manifold under pressure.

The disadvantage of this dispenser is the need for its operation to have a source of medium with high pressure and the flow rate of this medium (compressed air) with each cycle of the dispenser.

The objective of the invention is to provide such a flushing cistern, which would supply a portion of water to the collector of the flushing system of the toilet bowl under pressure without any additional source of pressure medium.

The task is achieved by the fact that in the proposed flushing tank, to create pressure when draining a portion of water, an air cushion is used, which will be formed in the bell of a sealed enclosure. In this case, the function of the shut-off valve with the float device is performed by gradually compressible air when filling the sealed chamber of the tank with water from the water supply network.

A water supply pipe, as well as a pipe connecting the tank to the toilet manifold, with a drain valve, are located at the bottom of the tank. In addition, the drain valve is equipped with a stem, which is necessary for a clear orientation of the valve relative to the seat during valve movements, and which serves as a rigid connection of the valve with the “unloading” membrane located in the upper part of the tank dome opposite the seat of the drain valve.

This membrane is made in such an area that the force on the membrane arising from the action of compressible air is slightly less than the force arising from the pressure of the water and the pressure of the spring closing this drain valve at an increased pressure inside the tank equal to the pressure of the water in the water supply network. This makes it easy to open the drain valve when flushing the toilet.

The technical result of the invention is the design of the flushing tank in two versions, which are presented in the drawings. In FIG. 1 shows a General view of the flush toilet bowl made with one tank, section.

In FIG. 2 - also, but with two tanks.

The proposed flush toilet water tank with one tank, shown in FIG. 1, consists of a housing 1, a housing cover 2, connected through a gasket 3 to the housing with screws 4. At the bottom of the housing, a pipe 5 is supplied from the water supply network and a drain pipe 6 with a drain valve 7 and its seat 8. The drain valve 7 is equipped with a stem 9 through thread 10, made at its free end, which is connected to the stem 11 of the flush switch button 12, which is hermetically sealed but movable in a rotational direction, with a membrane made in the form, for example, of a bellows 13 in the assembly of this joint 14. In addition stem 9 is equipped with a locking valve 7 en spring 15 contacting crossbar 16 through the bearing housing with the cover 2. This cover may be provided with a manometer 17 for monitoring the compressed air pressure (and the pressure in the water mains). The drain pipe 6 connecting the tank to the toilet flush collector is equipped with a throttle 18 for adjusting the water pressure in this collector.

The tank shown in FIG. 2 consists of a housing 19, a cover 20, in which two tanks of FIG. 1 with tanks 21 and 22, moreover, in the tank 21 the tank with one tank is completely repeated, and in the second tank 22 of a somewhat larger volume, water is supplied through the pressure reducing valve 23, while the rods 24 and 25 of both tanks are hinged 26 and 27 with a common lever 28 start button 29 mounted on the rack 30 of the cover 20.

The proposed flush toilet bowl works as follows. Attached to one (or two) toilets of the toilet bowl when there is free supply of tap water, a certain portion of water automatically accumulates in it with the corresponding compression of the air that was before the water supply in the tank reservoir (s). In this form, the tank is in a standby state. When opening the drain valve 7 (Figure 1), the water in the tank under the pressure of the compressed air in the same tank will rush into the corresponding collector of the toilet bowl. In the variant of the flushing tank with two tanks (FIG. 2), when flushing, due to the time difference between the opening of the drain valves due to, for example, a gap in the hinge 27, water will first rush to the flush from the tank 22, which is under slight pressure, due to the presence in the supply line a valve 23 for reducing the pressure of the tap water entering the tank. In some cases, this flush may be completed. In the “full” flush version, with continued action on the lever 28, the drain valve and the second tank 21 will open, after which the water from this tank will rush, for example, into the second toilet collector, equipped, for example, with nozzles twisting the water flow, the water from which will “remove »Into the flow of water from the first tank at a slight inclination towards the natural discharge, which will ensure the intensification of the flushing process.

Thus, the proposed invention will improve used in everyday life and, for example, in car building, toilets by applying water pressure in water mains (pipes), which has not been used before. In this case, the applied water will be saved due to the intensification of the flushing process and the cancellation of such a phenomenon as water leakage through the overflow channel, for example, with a poorly adjusted shut-off valve operating with a float device.
