DESCRIPTION:
BRIEF SUMMARY
This invention relates to a water-closet with a water-inlet opening and a lavatory pan arrangement.
In water-closet installations it is known to trigger the rinsing by a key button, whereby the known kind of rinsing cannot wash all parts of the pan, since the pan is not closed entirely. Further it is disadvantageous that during rinsing the lavatory cannot be used.
It is the object of the invention to provide a lavatory installation, in which those parts, which are expected to be absolutely clean may be cleaned and disinfected and be ready for further use immediately.
According to the invention, this object is obtained by a water-closet defined as here-above, whereby the lavatory pan arrangement consists of two essentially identical pans, which are movable into each others position by rotating them around a common axis.
Further details of the invention are explained with reference to constructional examples which are illustrated in the accompanying drawings, in which
FIG. 1 shows a sectional view of a water-closet according to the invention,
FIG. 2 shows an other embodiment of the invention in the same view, and
FIG. 3 shows a detail of FIG. 2 in a larger scale.
FIG. 1 shows a sectional view of a water-closet installation according to the invention which consists of a housing 10 with two pans 2, 2' which are disposed symmetrically in respect to an axis R which is inclined at an angle of 45.degree.. By rotating the pans which are fixed to the shaft W, driven by a motor M, in steps of 180.degree., each pan can be moved into the position of the other one.
The upper pan which is closed by a cambered cover 1, whose exact shape is determined by the rotation of the pan edges S.
The lower pan, which in respect to the upper one is rotated around 90.degree.--with reference to the drawing-plain and mirror inverted--is washed with spraying water which is sprinkled by nozzles 5.
Between the housing 10 and the wall 15 there is a chamber 4, in which the motor M, a pump P, a container D with chemical agents for the water, such as disinfectants and drying substances and several water-pipes 16-19 are disposed.
The installation works as it is described here-after:
After the use of the lavatory three processes are triggered one after the other by closing the cover or pushing a key button. Firstly a primary rinsing is accomplished by the pump P, which pumps water through the pipe 16 which discharges through the opening 12 into the upper pan 2. The waste water thereby passes from pan 2 through the opening 11 into a siphon 3 which serves as gas separation and which is filled by water, and further into the sink 14. Siphon 3 and sink 14 are disposed in a socle 8. After a predeterminable time the primary rinsing ends, whereafter by powering the motor M the shaft W is driven to rotate about 180.degree., thereby positioning the lower pan upwards and vice versa. After this the lavatory is free for further use. After rotating the pans the fine cleaning begins for the lowered pan, whereby with a plurality of nozzles 5 water is sprinkled at the lower pan. At the end of this cleaning process a disinfectant and a drying substance may be added to the sprinkling water to firstly obtain absolute hygienic conditions and secondly to speed up the drying period. The sprinkling water is discharged through a secondary siphon 6 into the sink 14 as well.
The rapid drying is important, since the edges S and S' of the pans which are washed as well as the inside of the pans are designed as a seat, and must therefore by dry cleaned and disinfected.
These processes are repeated after every single utilisation.
The pipes 16 and 17 disposed in the chamber 4 lead the water from the pump P to the opening 12 and to the nozzles 5 respectively. The pipe 18 connects the pump with the external water supply and the pipe 19 serves to convey the chemical agents from the container D to the nozzles, whereby the container comprises a dosing device. The lower part of the chamber 4 may also serve as water tank, whereby a tube would have to be provided which extends from the
