Description

Flushing device for toilet bowl

The useless model relates to sanitary equipment of toilets with low water consumption, in particular toilets of means of transport, and relates to devices that decontaminate flushing excrement in the toilet with a dosed portion of water using pressure, for example with compressed air.

A toilet flush device 1 is not known, comprising a water tank, a dispenser, a flush valve with a disk and a rod, a flush toilet collector in the form of an annular tube with water outlet openings, a pneumatic dispenser drive, the collector being connected to the tank by a pipe through a flush valve and a dispenser, which made with a housing, a cover and a flexible disk diaphragm clamped between them along the outer contour, separating the water cavity located in the cover from the air cavity in the housing, the water cavity communicating with the pipe from the tank through the inlet check valve, the cover is made with a central hole for water to enter the collector and is equipped with a metering stop for the diaphragm, and the air cavity is connected to the air distributor with the possibility of communicating the air cavity of the dispenser with the atmosphere when the flushing device is inoperative and with a compressed air source in the working position of this device .

In this design, the flush valve is made separately from the dispenser in its own housing. The valve disc is pressed against its seat by a spring and is actuated through the outgoing stem of the valve by depressing the pedal from it. This determines the complexity of the design of the device as a whole, its significant dimensions, the need to seal the rod when it exits.

Another disadvantage of this device is that the dispenser does not have a device that blocks the access of water to the collector after intensive flushing. As a result of this, the device 1 does not provide strict dosing - after the end of intensive flushing, water from the tank by gravity continues to flow into the collector until the toilet pedal is released.

Best device option

The flushing device for the toilet 1, according to FIG. A, comprises a water tank 3 connected by a pipe 4 through a check valve 5 with a dispenser having a cover 6 and a housing 7. A flexible diaphragm is clamped between the cover and the housing 8. A pressure disk 9 s is inserted into the plate bend of the diaphragm. a rubber washer 10 and a stem 11. At the end of the stem, a flush valve disc 13 is fixed. The cover 6 of the dispenser has a Central hole, the outer end of which is made in the form of a saddle for the disk 13 of the flush valve. A metering stop is attached to the lid 6 on the inside; an emphasis 12 having a central hole for guiding the rod 11 and a peripheral hole for water passage. These holes are made with the possibility of their overlapping pressure plate 9 and the washer 10 at the end of their working stroke up. The valve disk 13 is pressed against the seat by a spring 14. It is preloaded by draining; it is screw screw 15. The valve cover of the lid is connected to the annular collector 2 of the toilet bowl 1 through the nozzle 1. The space in the lid 6 of the dispenser located above the diaphragm 8 is the water cavity of the dispenser. The space located in the housing 7 under the diaphragm is designed for compressed air. This cavity is connected by a pipeline to the air distributor 16, I have it; the drive button 17. The air distributor has the ability to communicate the air cavity of the dispenser with the atmosphere when the button 17 is not pressed and with the compressed air source when the button 17 is pressed. The air distributor 16 is equipped with an inductor 18 at the outlet of air to the atmosphere. the valve 5 can be made, for example, in the form of a folding rubber ring (rubber washer), covering the inlet for water inlet.

The device operates as follows.

Previously, to bring the flushing device into operation, the upper cavity of the dispenser is filled with water. To do this, by pressing the button 17 do 2-3 test flushing, as a result of which air is displaced from the upper cavity of the dispenser and it is filled with water.

Duty wash cycles are as follows. When you press the button 17 of the air distributor, the compressed air enters the air cavity of the dispenser housing 7 and, acting on the diaphragm 8, transmits the pressure of the compressed air to the water in the upper part of the dispenser. Under the influence of this pressure, the check valve 5 closes and prevents water from leaving the dispenser in the tank 3. Under the influence of air pressure, the diaphragm 8 moves up. Together with it, the pressure disk 9 moves with the rod 11 and the disk 13 of the flush valve, overcoming the force of the compressed spring 14. The disk 13 opens the water outlet from the water cavity of the dispenser into the flush annular manifold 2. Water from the lower part of the water chamber the upper part of the dispenser through the peripheral holes of the metering stop 12. At the end of the upward stroke of the pressure plate, these holes are closed with a rubber washer, and the flow of water from the water cavity of the dispenser into the collector is stopped. The amount of water per flush (dose) is determined by choosing the appropriate height of the metering stop 12.

The second phase in the operation of the flushing device begins after releasing the button 17 of the air distributor. As a result of releasing the button, the compressed air from the air cavity of the dispenser goes into the atmosphere, and the diaphragm 8, disk 9 with the rod 12 and disk 13 are lowered by the action of the return spring 14, water from the tank through the check valve 5 fills the water cavity of the dispenser. The throttle 18 installed at the air outlet to the atmosphere, due to the appropriate selection of the diameter of the throttling hole, provides a slower lowering of the diaphragm 8 and valve disc 13 so that the water chamber is not filled with air from the manifold 2, but with water (having a large inertia) from the pipe 4. At maximum during the diaphragm 8 downward, the flush valve disk 13 is pressed by a spring 14 against the valve seat and closes the water outlet from the dispenser, thereby achieving the initial position for repeated flushing cycles.

The proposed device, in comparison with the prototype, in which the dispenser and the flush valve are made in the form of separate blocks, simpler and more compact, since the flush valve is located inside the dispenser. In addition, the introduction to the design of the metering stop with holes for
