Description

96628

The invention relates to a sanitary system and a method for the utilization of domestic water used for sanitary purposes. The invention relates to a sanitary system and a method for the utilization of domestic water.

Sanitary systems are known in the prior art in which dirty domestic water is used as flushing water for a toilet seat. In this regard, we refer to U.S. 5,341,529, 10 U.S. 5,317,766, and U.S. 5,274,861.

State-of-the-art solutions are relatively complex and do not allow for the cost-effective replacement of old sanitary solutions. Contaminants in the wash water clog the prior art equipment, making cleaning, maintenance and repair expensive.

The prior art requires repeated manual washing of the containers to avoid odor nuisance and bacterial problems.

This application discloses an ice system in which the rinsing water of a water closet is taken from drainage water, for example from hand basin water. The system preferably uses a reversing valve in connection with the hand basin, which has an adjustable so-called drainage water flow to the storage tank. The effluent from the storage tank is further pumped into the flush water tank of the toilet seat.

According to the invention, a recycling system is used for the drainage water, in which the water pumped from the storage tank 25 is first directed to the flushing water tank of the toilet seat and from which tank there is still a return connection back to the storage tank. The system solution further comprises a dosing opening in connection with the storage tank, from which the detergent can be added to the storage tank. The connection between the flushing water tank and the storage tank has a pump which is operated via a flushing water tank limit switch. Whenever a limit switch 30, e.g. a buoyancy switch, indicates that the water level in the flushing tank has fallen below a certain limit value, a pump is used and water is pumped from the storage tank to the flushing water tank.

According to the invention, the storage tank preferably comprises a level control. The surface height adjustment can consist, for example, of an overflow pipe that opens into the drain, the height position of the upper end of which in the storage tank is adjustable. When the liquid surface in the storage tank is above the end of said overflow pipe, the water in the storage tank-5 overflows into the drain connection.

According to the invention, a valve is preferably used in connection with the hand basin. By turning the valve stem, the drain water flow into the storage tank can be opened and cut off.

In a preferred embodiment of the invention, the flushing water tank comprises in connection with an additional tank to which clean water can be directed from outside the ice system and from which tank there is a connection via a non-return valve to the water line between the storage tank and the flushing water tank. There is also a non-return valve between the storage tank and the flushing water tank.

15 In this case, the flow to the flush tank of the toilet seat can be controlled either from the storage tank or from the auxiliary tank, depending on whether the water pressure at the outlet of the non-return valve at the outlet of the auxiliary tank is higher or lower than in the auxiliary tank itself.

In one embodiment of the invention, the sewage water is led from the shower by means of a pump device 20 directly to the storage tank.

When a directional valve is used in connection with a hand basin, it is preferably a ball valve or a cylinder valve. The movable control piece of the valve comprises a curved control surface. The valve is preferably controllable from the level of the upper edge of the hand basin by turning the handle associated with the valve stem to the position determined by the desired control.

The invention is characterized by what is stated in the claims.

The invention will now be described with reference to the accompanying drawings, in which certain embodiments of the invention are shown, to which, however, the invention is not intended to be exclusively limited.

The storage tank 20 has a connection 25 to the toilet seat flushing water tank 12. Correspondingly, the flushing water tank 12 has a return connection 26 back to the storage tank 20. The connection 25 comprises a pump 27 which is operated, for example, electrically by means of a height switch K in the flushing water tank. When the surface height in the flushing water tank 10 has fallen below a certain limit value, this is indicated by the limit switch and the pump device 27 is used, pumping water from the storage tank 20 to the flushing water tank 12 via pipeline 25. In connection with the flushing water tank 12 there is still a return acts as an overflow pipe for the flushing tank, from which, as a possible overflow, water is led from the top of the tank to the storage tank 20 or when a washing cycle is used. The stepless level adjustment in the storage tank allows the unit to be suitable for installation in different toilet seat types and models at different installation heights. Line 25 and / or 26 preferably also comprises a filter 100. Clean water for the hand basin is taken from the tap 200. The storage tank 20 comprises a plug 20 Dj. By opening it, detergent can be added to the tank. Through connection D2, for example, water used in the shower can be led to the tank 20.

The return flow implemented according to the invention and the recirculation flow by means of the pump 27 make the system reliable and leak-proof and enable the system 25 to be washed reliably and easily. The backflow system thus ensures reliable overflow protection for water flowing from the storage tank. In the wash cycle program, the pump 27 is forcibly switched on regardless of the position of the float K in the rinsing water tank and the limit switch.

30 By using a directional control valve 19 below the hand basin 17, it is possible to fill the storage tank if necessary and also to clean the washing water 1:11) I l JS »::! 5,96628 leads to a storage tank to provide recycled washing with clean water. In the washing cycle, clean water drained from the tap 200 can be circulated, to which a detergent or plug Dj can be added, by opening the acid / base liquid can be added and it can be circulated between the storage tank 20 and the rinsing water tank 12.
