Definitions

• the invention relates to a flushing device for toilets, which contains a flushing tank with an air tank, a mains connection socket, a Nentilanschlußstutzen, a flushing socket, a valve housing with control element and an injector tube.
• the injector tube connects to the suction element.
• the conventional flushing devices are described in detail in the book “Water Supply, Sewerage, Gas Supply for Buildings” by Ballai-Marton (Technischer Verlag, Budapest, 1977), pages 593-599.
• the conventional flushing devices have an open water tank of approximately 8 liters, a float valve, and a weight valve. When rinsing the whole amount of water has to shoot out of the container, and therefore this solution is not economical.
• the closed containers with air tanks also use the pressure in the water line when flushing.
• Such a solution is announced in the patents HU 174.527, HU 190.422 and FR 2.122.069.
• Their disadvantage is that the air continuously escapes from the pressurized container with the rinse water. After a certain time, the container loses its air cushion and then functions like a valve that is connected to the water network without a container. This means that the replacement of the air cushion requires maintenance.
• the US Pat. No. 5,046,201 thus describes a flushing container under pressure, with a pressure regulator, in which the water feeds the injector and the injector sucks air into the container.
• the flush valve is provided with rods.
• the publication WO 98 / 39.522 gives a flushing system with a pressurized, multi-branch valve known.
• the US Pat. No. 5,136,732 contains a flushing device with a piston and a needle valve.
• the patent document JP 6.158.699 represents a pressurized container with a vacuum valve.
• the patent document HU 205.409 describes a device which also contains an injector, a weight or spring-loaded outer valve for the air supply.
• a common disadvantage of the solutions mentioned is that they are relatively complicated, furthermore that the various valves, pressure regulators easily combine and clog, that is, require maintenance.
• the aim of the invention is to eliminate the disadvantages of the previous solutions, the design of such a flushing device, which is simple, requires no maintenance and air supply by the operator, is quiet, water-saving and extremely reliable.
• the basis of the idea of the invention is the knowledge that if the air supply is released through an opening during the flushing process without moving parts and the flushing water jet is deflected and stabilized for the introduction of the air, we obtain a more advantageous solution than before.
• the device according to the invention is a flushing device for toilets, which contains a container provided with an air tank, a mains connection piece, a flushing piece, a valve housing provided with a regulating element and an injector tube, to which an suction element connects to the injector tube, in such a way that the Valve housing under the control element, an air refill opening, while above the control element - expediently inserted into the valve housing - the jet pipe suitable for deflecting the rinsing water is arranged, in the jet pipe and / or an air introduction chamber is left free next to it.
• the suction element is inserted in the lower part of the injector tube and is provided with at least one inlet connection opening into the container.
• the air inlet chamber is delimited by a vault, which leads the air to the air boiler.
• the part of the jet pipe which projects into the valve housing contains a stabilization chamber which determines the direction of the water jet.
• the injector tube, the suction element, the jet pipe and the flushing nozzle are coaxial.
• a supplementary unit is installed between the suction element and the jet pipe, the supplementary unit is provided with a suction mouth suitable for increasing the water discharge.
• the supplementary unit surrounds a merging chamber.
• the inventive flushing device for toilets has numerous advantages. It is extremely simple and reliable, apart from the control device with which the user starts the flushing and which also switches it off, the device contains no moving components. The device requires no warning and contains no parts subject to sintering and clogging. The function is quiet and water-saving. The user can turn off the flush at any time. The air supply runs automatically during the flushing process.
• an air refill opening also has the particular advantage that no valve preventing back suction has to be used for the device. In the event of a malfunction in the water network, the air refill opening stops the suction effect and prevents the dirty water from possibly entering the water network.
• FIG. 1 longitudinal section of the device
• Fig. 2 Cross section of the jet pipe at the point I-I according to Fig. 1
• Fig. 3 Cross section of the injector pipe above the suction element.
• the container 1 is arranged vertically. At the very top is the network connection 2, the upper part of the container 1 forms the air tank 17.
• the current water level is identified by a triangle.
• the container 1 can be made of plastic, metal or a combination thereof. It can consist of one or more pieces.
• the injector tube 3 is in the longitudinal axis of the Container 1 and can be narrow or have the diameter shown in Fig. 1.
• the suction element 4 is installed in the lower part of the injector tube 3 and has two inlet ports 12 which open into the container 1.
• the suction element 4 and the injector tube 3 are coaxial.
• the lower part of the injector tube 3 may be tapered.
• the valve housing 6 is under the container 1 and expediently connects to the flushing nozzle 11. If necessary, the valve housing is assembled with the container.
• the control element 10 can be a simple shut-off valve or else a remote-controlled valve. Under the control element 10 there is the air refill opening 7. Between the suction element 4 and the control element 10 there is the jet pipe 15 suitable for deflecting the rinsing water.
• the jet pipe 15 comprises the stabilization chamber 14, next to it the air introduction chamber 5.
• the air introduction chamber 5 is at the top Defined vault 16, which directs the air into the air boiler 17.
• the jet pipe 15 and the flushing nozzle 11 are expediently coaxial.
• the supplementary unit 8 is inserted between the injector tube 3 and the jet tube 15. The supplementary unit 8 connects to the container 1 through the suction mouth 13 suitable for increasing the water discharge.
• the supplementary unit 8 comprises the meeting chamber 9.
• the jet pipe 15 is shown in cross section with the air inlet chamber 5.
• the cross section of the injector pipe 3 is shown with the inlet port 12 of the suction member 4.
• the supplementary unit 8 serves to increase the effect of the suction element 4 as a secondary element.
• the suction element 4, the injector tube 3 and the supplementary unit 8 used as required are collectively called "water jet pump”.
• the inventive rinsing device can also be implemented in other versions within the scope of patent protection, e.g. the suction element 4 can also be arranged under the injector tube 3.
• the flushing device according to the invention works as follows:
• Fig. 1 the path of water is marked with an arrow, the path of air with a broken arrow.
• the user of the toilet opens the control element 10.
• the pressure in the air tank 17 corresponds to the pressure in the water pipe.
• the water escapes from the container 1 and the air pressure in the air tank 17 gradually drops.
• the fresh water flows from the water pipe with gradually higher pressure into the injector tube 3.
• the water flowing into the injector tube 3 exerts an injector effect on the suction element 4 and the supplementary unit 8, as a result of which the water in the container 1 flows through the inlet nozzle 12 and the suction mouth 13 connects to the main flow and mixes with it in the jointing chamber 9.
• the reduction in the amount of water in the container causes a vacuum to form in the air tank 17. Under the effect of this pressure difference, air flows through the air refill opening 7 and the air introduction chamber 5 into the air tank, which automatically replaces the amount of air entrained in the flushing water.
• the water in the container 1 which joins the tap water under the action of the injector, assumes its cross-section in the stabilization chamber 14 of the jet pipe 15 and while it flows through the control element 10 it approximately maintains its cross-section. The edge of the water flow is indicated by a dashed line.
• the shape of the jet pipe 15 makes it possible for the water flow not to completely fill the cross section of the control element 10 and the valve housing 6 and thereby promote the inflow of air into the air tank 17.
• control element 10 is shut off. Then the tap water fills the container 1 through the injector tube 3 until the pressure of the air cushion in the air tank 17 is balanced with the pressure in the water pipe.
• the inventive flushing device is used for water-saving and reliable washing of toilet bowls.
