CZ273295A3 - Double-acting flushing system of lavatory pan with adjusted mode of operation - Google Patents

Abstract

The device consists of a housing (1), a bottom (10), an opening (11), the jacket tube (14), at least one latch (9) rotatably mounted on the underside bottom of housing (10) drain pipe (3), seal the valve (6), the stop (15) of the bottom float, of the upper float stop (16) of the hinge (18), bottom float (4) with partition (17) and from the upper float (16). the device is used for partial and total discharges of water from toilet containers. Partial water discharge is the bottom float (4) is locked to the housing (1) by a latch (9) rotatably mounted on the bottom bottom (10) with an opening (11) that slows the discharge water from the jacket (1) and thus the float (4) a closing the main valve.

Description

Double-action toilet bowl flushing system with adjusted

Technical field

The present invention relates to a toilet bowl flushing device, i.e., a drain valve, into a toilet flushing vessel for draining water from the vessel and, after emptying, automatically closing the spout.

BACKGROUND OF THE INVENTION

The toilet flushing cisterns with economy mode for partial and total emptying of the tank are known in versions with two valves of different heights separately operated, or the valve and the possibility of interrupting the discharge of any quantity controlled by the operator. The valve and the possibility of interruption of the outlet by the operator allow to flush such a small amount of water that the bowl is not rinsed perfectly and thus the hygienic requirement of the flushing system is not guaranteed.

SUMMARY OF THE INVENTION

The technical solution according to the invention removes these drawbacks in that the drain valve into the cisterns of the toilet flushing device allows the selection of a small flush of a specified amount or all of the water from the container by a single valve controlled by a single rod. This is enabled by two floats on the central tube with one seal. The upper float is designed to select a small flush of water and is secured to the central pipe by a stop. The bottom float is for emptying the container and only operates when released from the valve housing.

In the case of a small flushing of water, it pulls on the central pipe, lifts the seal from the seat and the upper float with descending level closes the valve again, while the lower float is blocked to the valve body.

The float is unlocked for the entire flushing operation after the valve support plate is moved on the latch.

Overview of the drawings

BRIEF DESCRIPTION OF THE DRAWINGS The invention will be explained in more detail with reference to the drawing, in which FIG.

DETAILED DESCRIPTION OF THE INVENTION

The apparatus comprises a housing 1 which is attached ke- valve seat 2 and the means of sealing washers and nuts £ 20 connected to the reservoir 19 £ _0's casing and has a bottom 10 with an aperture 11 and sheath tube 14. At the bottom of the housing is equipped with at least one pawl £ 1, rotatably mounted on the underside of the bottom of the housing 10, a drain pipe 4 with a valve abutting the seal 6 on the valve seat 2 extends through the center of the housing 1 and the float. Drainage pipe 2 ^M, and the lower float stop 15 and upper stop 16 of the float with the hinge eye 18 of the lower float and the partition 17. £ nákružníkem recess 12 and a groove 13. The upper float 2 J ^e adjustable stop 16. At low water flush. It is not blocked by anything. The bottom float 6 with the baffle 17, the collar 12 and the groove 13 is blocked by a pawl ₉ pivotally mounted on the bottom 10 of the housing 1 through which the bottom float tube 8 passes and its tube is axially discharged with one valve. The bottom float 8 blocks at least one latch 6 which is released after overcoming the latch resistance for the entire flushing of the water from the tank after the support plate 6 has been driven from the groove of the bead 12. Thereby, the bottom float 4 is brought into operation and, after the float has been caught, the stopper 15 carries out the shut-off valve for the entire time the water is discharged from the tank and the float shell.

After the water has drained, the valve will drop and the latch 2 will again lock the float. For both water discharges, both small and large quantities, the outlet eye 18 is controlled by the lifting eye 18 by a single control device.

Claims (4)

PATENT CLAIMS Λ slU · '* + -, .7 Ze-rigor / g of partial and total water discharge from the WC container, characterized in that the bottom float (4) is blocked to the housing (1) by a pawl (9) rotatably mounted on the bottom bottom (10) with a hole (11), which slows down the flow of water from the casing (1) and thereby decreases the float (4) and closes the main valve », Device according to claim 1, characterized in that the latch (9) blocks the lower float (4) to the valve housing (1) behind the collar (12) in the groove (13). Device according to claims 1 to 2, characterized in that, for the delayed lowering of the lower float (4) compared to the lowering of the water level in the toilet tank in the jacket (1), it is controlled by the opening (11) in the bottom of the jacket (10). The device according to claims 1 to 3, characterized in that, in order to distinguish between the total and partial draining of the WC container, the lower float (4) is pulled down with greater resistance before the latch (9) is released.
