Benefits of technology

[0010] Therefore, the present invention has been made in view of the above problems, and it is an object of the present invention to provide a toilet water saving apparatus linkable with a bidet, and a water saving method thereof, the bidet being installed to a toilet for the washing of the genital and posterior parts of the user after urination or defecation, wherein the apparatus and method enable the water volume charged in a water reservoir of the toilet to be adjusted according to the type of waste to be disposed so that a small volume of water is supplied to flush urine, and a large volume of water is supplied to flush excrement, resulting in prevention of unnecessary and significant consumption of water which is not required to flush urine.

Problems solved by technology

When considering the fact that the frequency of urination is higher than the frequency of defecation, the conventional toilet exhibits a problem in that it consumes significant volumes of water which are not required to flush urine.
When using the bidet, in addition to the water volume required per flush, it requires an additional volume of water used to wash the genital and posterior parts of the user, resulting in increase in consumption of water.
In conclusion, using a constant volume of water regardless of the type of waste to be disposed results in consumption of unnecessary and significant volumes of water in connection with the fact that the frequency of urination is higher than the frequency of defecation.
Flushing toilets is the major consumption activity in most homes, and nowadays, such waste of water in connection with toilets reaches a dangerous level unsuitable to many countries suffering from a lack of water.

second embodiment

[0035] Referring to FIG. 4 illustrating the present invention, to a supply tube 31a is installed a reservoir inlet tube 60 for supplying the washing water 32 to the water reservoir 33, and a bidet inlet tube 61 for supplying the washing water 32 to the bidet 40. These inlet tubes 60 and 61 are independently operable, and thus a reservoir valve 47a and a bidet valve 52a are installed to the reservoir inlet tube 60 and the bidet inlet tube 61, respectively.

third embodiment

[0036] Referring to FIG. 5 illustrating the present invention, a supply tube 31b is used to supply the washing water 32 to the water reservoir 33, and a bidet inlet tube 71 is connected to a certain point of the supply tube 31b for supplying the washing water 32 to the bidet 40. The bidet inlet tube 71 has a bidet valve 70.

[0037] The supply tube 31b is provided with a hand-operated valve 72 at a certain position between the bidet valve 70 and the water reservoir 33. In case of interruption of electric power, according to the selection of the user, the hand-operated valve 72 is operated to manually open or close the supply tube 31b in order to charge the washing water 32 into the water reservoir 33.

[0038] Under normal conditions, in order to allow the washing water 32 to be charged automatically into the water reservoir 33, to the supply tube 31b is connected a bypass tube 75, which extends around the hand-operated valve 72. In this case, a reservoir valve 73 is installed to the byp...

fourth embodiment

[0041] Referring to FIG. 6 illustrating the present invention, to a supply tube 31c is installed a three-way pump 93, which has a single inlet 90, and two outlets 91 and 92. To the outlets 91 and 92 of the three-way pump 93 are connected a bidet inlet tube 94 and a reservoir inlet tube 95 for supplying the washing water 32 to the bidet 40 and the water reservoir 33, respectively. Thereby, as the washing button 45 and the supplement button 46 of the control pad 36 provided at the control pad 35 of the bidet 40 are selectively pressed, the three-way pump 93 is selectively opened or closed by the controller 50.

Abstract

Disclosed herein is a toilet water saving apparatus linkable with a bidet, and a water saving method thereof. The water saving apparatus comprises branch tubes connected to the supply tube for supplying the washing water to the water reservoir and the bidet, respectively, a three-way valve installed to the branch tubes therebetween, and a urination water level sensor and a defecation water level sensor installed inside the water reservoir of the toilet for detecting a urination water level and a defecation water level. The three-way valve has a reservoir valve and a bidet valve for allowing the washing water to be selectively supplied to one or both of the bidet and the water reservoir. The bidet valve of the three-way valve is adapted to be opened or closed by a controller as a bidet button provided at the control pad is operated, and the reservoir valve of the three-way valve is adapted to be opened or closed by the controller according to the operation of a washing button or a supplement button provided at the control pad and according to signals from the urination water level sensor and the defecation water level sensor. The present invention results in prevention of unnecessary and significant consumption of water which is not required to flush urine.

Description

BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The present invention relates in general to a toilet water saving apparatus and method, and more particularly to a toilet water saving apparatus linkable with a bidet, and a water saving method thereof, which can allow the water volume used to flush a toilet to be adjusted according to the type of waste to be disposed, namely, according to whether the waste is urine or excrement, by means of a controller provided in the bidet as well as water level sensors provided in a water reservoir of the toilet. [0003] 2. Description of the Related Art [0004] In general, conventional toilets consist of a bowl fitted with a hinged seat, and a water reservoir located behind the bowl so that it is connected to a certain water supply facility for storing a constant volume of water required to flush the toilet. [0005] In such a conventional toilet, regardless of the type of waste to be disposed, namely, according to whether the wast...
