Title of Invention


Abstract This invention relates generally to the draining of the water, the food particles and other tiny waste particles. The conical shape or dome shape of the wash basin overcomes all the draw backs in the conventional types and ensures advantages over the conventional basins. The increase in drain area by 150% ensures that clogging is eliminated. The big long waste collection basket ensures a day's waste can be collected, which avoids frequent cleaning.

The following specification describes the nature of this invention-Technical field of the Invention - This invention relates generally to the draining of the water, the food particles and other tiny waste particles while using sinks, wash basins, wash domes in private and more particularly in public places.
The existing design of the washbasin is suitable for use by small families and a small group of people and for the western lifestyle, where spoons and forks are used while eating, where food particles do not stick to hands as one has minimum direct contact with food. Further tissue paper or paper napkins are used to clean ones hands, thus, hands which are almost clean, are washed with water, in a wash basin. People with this lifestyle if use the wash basin to wash hand clogging of the drainage pipe is minimal, whereas in India and Asian countries, were the lifestyle and food preparation is such that, one prefers using bare hand to consume food directly. After eating food, we use the Wash Basin to clean hands and also rinse our mouth with water. The food particles especially rice particles, etc., fall into the basin clogging the basin. At times, in public places like Marriage halls, Railway stations, Bus stations, etc, where lunch boxes or Tiffin carriers are washed, clogging of the drainage pipe is very rapid causing the drain and basin will turn unusable, demanding ongoing maintenance to keep the basin clean.
The above-mentioned problems are over come in the new design. The basin structure is made of conical shape, which eliminates all the above-mentioned problems.
The mouth of the drain area is increased by about 150% reducing the scope of clogging. The very shape ensures water running down all over carrying the waste particles along with it, leaving it dry. Thus no need for constant maintenance.
Apparatus in brief:
One of the preferred embodiment for this washbasin cone shape is that, molded plastic of a predetermined density and thickness can be used for its manufacturing. Molded

plastic reduces cost of manufacturing and can be easily maintained. Another preferred embodiment is to use ceramic for this proposed wash dome or conical shape has wash. Another preferred embodiment is Stainless Steel, though it will be strong, cost will be more than molded plastic.
FIG. 1 is a schematic, vertical cross-sectional view of an apparatus embodying the present invention.
FIG. 2 is a schematic, top plan view of the apparatus shown in FIG. 1.
FIG. 3 is a schematic, vertical cross-sectional view of the dome or the lid with a knob placed on the steel rods, serves as a detachable cover to the drainage system.
FIG. 4 is a schematic, vertical cross-sectional view of a waste solid holding area, showing the basket.
FIG. 5 is the schematic, vertical cross-sectional view of the entire conical basin with the basket.
It is to be understood that the invention may assume various alternative orientations and step sequences, except where expressly specified to the contrary. It is also to be understood that the specific devices and processes illustrated in the attached drawings, and described in the following specification, are simply exemplary embodiments of the inventive concepts defined in the appended claims. Hence, specific dimensions and other physical characteristics relating to the embodiments disclosed herein are not to be as limiting, unless the claims expressly state otherwise.

For a more complete understanding of the invention, reference is hereby made to the drawings, in which:
Fig. 1 illustrate the conical shape or dome shape wash basin, the cone denotes as marked 1, the 2 rods made of plastic or steel on which the waste collection basket will rest is marked as 2. The hooks on which the 2 rods rest is marked, as 3 and 4 is the hook that is fixed to the cone. 5 are the holder that fixes the cone to the wall, where the basin is to be fixed.
Fig.2 illustrate the vertical view of the dome or cone or basin and the 2 rods marked as 6 which projects one inch from the rim of the wash dome, this projection provides a one inch gap all round the dome and the basket facilitating easy drain for water along with waste particles like rice. This gives and increased drain area of 150% more, over and above the than the conventional washbasin.
The novel idea of this convention is, the conventional basin is replaced by a dome (Fig.3), wherein the two steel rods are marked at 6 and the knob to lift the dome to fix or remove the basket within is marked as 7.
Fig. 4 is the waste collection basket, showing four number of hooks marked as 8 on
which the steel rods or dome will rest. The basket is fixed on these hooks marked as
9. A steel rod marked as 10 is used for lifting the basket for replacing or cleaning
Fig. 5 shows the complete picture of the dome or the conical wash basin.
The present invention can be used in marriage halls, when one washes the hand, rice particles and other solid food waste, is washed with the water. In other places, like Railway stations and Bus stations people wash not only their hands, also wash small utensils like Tiffin carries and throw the left over into the dome or the conical basin, all this will flow down along with water. The waste easily flows done, since the dome is smooth and the shape of the dome helps the waste to slide down in the manner described above.

This waste will slide into the waste collection basket. This waste collection basket is porous and collects the waste but allows the water to drain out into the gully trap. The wastebasket can be of a predetermined length, designed to collect and hold the waste for a longer duration. Thus cleaning once or twice in a day is sufficient Eliminating the constant maintenance or cleaning, which is required in the conventional type of washbasin.
The basket will have a bulging rib so that the basket fits tight at the top and does not tilt. The basket will have steel rod of predetermined length down for lifting operation. The basket will stand on two parallel steel rods, which will be at proportionate down the length of the cone. These rods are fitted to the cone.
The present invention provides a very cost effective, timesaving and environmentally sensitive method for removing solid waste from water holding areas and the like. Since the water over the sludge is not removed, the process is non-invasive, and the adverse ecological effects of odor and the like are avoided. The dewatering of the solid food waste is quite complete, thereby greatly reducing the volume of solid food waste that must be transported to an appropriate disposal site.
Those skilled in art shall catch the concept with ease and since any wash basin should have standard measurements the inventor herein maintains the standard dimensions and height, which can also adjusted to once preference.
In the foregoing description, it will be readily appreciated by those skilled in the art that modifications may be made to the invention without departing from the concepts disclosed herein. Such modifications are to be considered as included in the following claims, unless these claims by their language expressly state otherwise.
