2. Description of the Background

Saving bathroom water is one of the ways to conserve water in modem society, especially in areas where there are constant shortages of water. Many inventions have been declaimed to save water in the house, For example, there are a few water saving inventions that reuse water in bathroom.

For example: U.S. Pat. No 6,425,148 to Chen; Jung-Hua issued Aug. 17, 2001 shows a water-saving device for a toilet comprises a tank, a tank lid mounted on top of the tank, a sink formed on the sink and communicated with a chamber in the tank via a hole in the sink, and an output tube having a lower end communicated with an inlet tube and an upper end for supplying water into the sink. A guide tube is mounted in the tank and comprises an upper end communicated with the hole of the sink and a lower end immersed in the water in the chamber of the tank such that drainage of water in the sink via the hole of the sink and the guide tube into the chamber of the tank is almost silent.

U.S. Pat. No. 7,927,481 to Martinello; Settimo issued Mar. 20, 2008 shows System for the recovery of washing liquids used in showers, wash basins, and/or baths, including a first decantation tank provided with at least one inlet connected to a downflow point of washing water, a second collection tank, an overflow partition wall adapted to separate the two tanks, a sewer drainage at the bottom of the decantation tank, adapted to be closed by a plug that can be raised by a float in the collection tank according to the liquid level therein, a drawing pump in the collection tank, controllable by a relay, or electrical float, indicating the liquid requirements of a fixture, a pipe connecting the pump of the collection tank with the fixture, the relay, or electric float, electrically connected with the pump and a valve of the fixture and controlled by a float in the collection tank for closing the electrical power supply to the pump and opening the electrical power supply of a valve for liquid flow to the fitting.

There is however no invention that directly reuses water from bathroom sinks for the purposes of toilet flushing. In a bathroom where space is limited, a space-saving bathroom sink will provide more space for other uses in everyday life. The new invention of a folding space- and water-saving bathroom sink toilet system provides the functionality mentioned above. This invention links the functionality of a combined bathroom sink and toilet system with the ability to reuse sink water for the purposes of toilet flushing.

BRIEF SUMMARY OF THE INVENTION

It is, therefore, a primary object of the present invention to provide a folding concealed bathroom sink for saving both space and water in conjunction with conventional toilets. This folding bathroom sink toilet system sits on the top of lid of any kind of toilet tank either existing in a bathroom or bathrooms in newly built houses, folds for space-saving and deploys for use above a toilet.

This new device is intended to control both the amount of water added to the toilet water tank and the water used for toilet flushing.

It is another object to collect water from everyday use and to store water in a conventional toilet for a second use. New device is invented to control both the amount of water added to the toilet tank or water for flushing toilet.

It is another object to provide a space-saving bathroom sink by putting the sink on top of a toilet tank. The space-saving feature of the sink is further improved by making it foldable to the width of a conventional toilet tank.

It is another object to save time and cost by combining a bathroom sink and a toilet. The new invention uses only a single water tap pipe system including one cold water inlet pipe, one hot water inlet pipe, and one drain pipe for both bathroom sink and toilet, saving one cold water inlet pipe and one drain pipe when compared to conventional bathroom. This in turn saves more space for the bathroom.

It is another object to reduce work needed to clean blocked drain pipes in a conventional sink system with a trap pipe under the sink where waste material such as hair is usually gathered. The new invention conducts water from sink to the toilet water tank which links to huge drain pipes to avoid blocking drain pipe.

It is another object to reduce pollution from chemicals needed to clean blocked drain pipes in a conventional sink system where a trap pipe under the sink usually collects waste material such as hair. The new invention conducts water from the sink to the toilet water tank which links to larger drain pipes thus avoiding any drain pipe blockage and therefore no chemicals are needed.

It is another object to make the bathroom a more enjoyable place. In the folded position the folding bathroom sink covers all items on the storage platform, making the bathroom appear neater, cleaner and more orderly. The art design on both sides and back of the bathroom sink allows one to put different kinds of art photos, especially on the back of the sink which faces outside when the sink system is in the folded position.

It is another object to provide an easy to install and disassemble bathroom sink toilet system. Anyone using a screw driver can install the sink by attaching four screws to the wall above the bathroom toilet. The rest of the setup can be completed manually. The opening and closing of the folding bathroom sink can be operated by a single handle due to the mechanic holding and connecting.

It is another object to provide a safe sink platform, since the two supporting legs, along with the mounting screws in the wall, provides additional support of the system.

DETAILED DESCRIPTION OF THE INVENTION

FIGS. 1, 2, and 3 are the perspective illustrations of the folding space- and water-saving bathroom sink toilet system. The folding bathroom sink overtop 102 the toilet tank has the same width of the toilet tank, and the inner side of 104 the sink is not visible when it is in the folded position. When the folding bathroom sink is deployed for use, it extends to the front edge of the toilet so the toilet is covered and not visible from atop. This system can be installed on 103 the lid of any kind of toilet on the market.

One-hand operation pulling 107 the handle for washing platform allows one to unfold the space- and water-saving bathroom sink toilet system. This operation also lays down 106 the fold-down legs, allowing 105 the washing platform for sink to be fully extended. All items in 501 the collapsible cabinet and the inner side of 104 the sink with art design on both sides display in front of users. The operation process is provided by 1006 the meshing ball as shown in FIG. 10 and 1306 the washing platform inner inclined plane as shown in FIG. 13. Used water is directly conducted to 102 the toilet tank through 1005 drain outlet To restore to the folded position for the bathroom sink toilet system one needs only to push upward 107 the handle for washing platform as shown in FIG. 1.

For the use of the toilet, one can first check water amount in 102 the toilet tank through 907, 908, and 909 the water level LED indicators. If 907 the empty tank water level LED indicator is on, there is no or little reusable water in 102 the toilet tank from 104 the sink. One needs to add fresh water to 102 the toilet tank by pushing either 1202 the push-button switch for adding half tank of water or 1203 the push-button switch for adding full tank of water. Pushing 1202 the push-button switch for adding half tank of water allows one to add a half tank of water to 102 the toilet tank. This is done through a wire connecting to 809 the sliding low water level lock. The drop of 809 the sliding low water level lock to half the height of 102 the toilet tank will in turn lower the height of 807 the actuating arm coupling water-stopping valve and water level floats in 102 the toilet tank and subsequently open 808 the water-stopping valve for adding water. When 804 the low water level float reaches certain height in 102 the toilet tank, a spring on 804 the low water level float will lift 807 the actuating arm coupling water-stopping valve and water level floats, locking 808 the water-stopping valve when the toilet tank is half full. 804 the low water level float will stop rising due to 811 the locking pin for setting the position of low water level float.

Pushing 1203 the push-button switch for adding a full tank of water allows one to add a full tank of water to 102 the toilet tank. This is done through another wire connecting to both 809 the sliding low water level lock and 810 the sliding high water level lock. The drop of 809 the sliding low water level lock and 810 the sliding high water level lock will in turn lower the height of 807 the actuating arm coupling water-stopping valve and water level floats to the lowest level in 102 the toilet tank and subsequently open 808 the water-stopping valve for adding water. When both 804 the low water level float and 805 the high water level float reach certain height in 102 the toilet tank, both 804 the low water level float and 805 the high water level float will lift 807 the actuating arm coupling water-stopping valve and water level floats to the height so that 809 the sliding low water level lock and 810 the sliding high water level lock reset to the location on 813 the valve platform through 812 the lock resetting spring. This will lock 808 the water-stopping valve when 102 the toilet tank is full. Flushing the toilet which lowers the height of 807 the actuating arm coupling water-stopping valve and water level floats in 102 the toilet water tank will not trigger 808 the water-stopping valve. Therefore water will not be added to 102 the toilet tank automatically.

The above embodiments are only used to illustrate the present invention, not intended to limit the scope thereof. Many modifications of the above embodiments can be made without departing from the spirit of the present invention.
