Abstract
Description
- The present invention relates to a toilet bowl, and more particularly, to a water-saving toilet bowl that differently adjusts amounts of water discharged to a body from a water tank according to urination and defecation, thereby saving the amount of water consumed, and that allows an internal air in a discharge passage to flow to the outside to form a negative pressure in the discharge passage when waste and water in the body are discharged along the discharge passage, so that the waste and water are discharged gently to allow the treatment after the urination and defecation to be easily carried out even with a relatively small amount of water.
- A toilet bowl is generally used at the time of urination and defecation.
- The toilet bowl includes a body for supporting a user in a state sitting thereon in such a manner as to receive waste at the time of urination and defecation and a water tank disposed on one side of the body to store water for washing the interior of the body at an internal space thereof. Accordingly, the user sits on the body at the time of urination and defecation, thereby taking a comfortable posture upon the urination and defecation, and after the urination and defecation, moreover, the water stored in the water tank is discharged together with waste in the body to the outside of the body, while washing the interior of the body, thereby allowing the treatment after the urination and defecation to be sanitary.
- After the urination and defecation, however, a general toilet bowl discharges about 12 to 15 ℓ of entire water stored in the water tank to the interior of the body, thereby undesirably causing a big problem in the water consumption for treatments after the urination and defecation.
- So as to minimize the amount of water consumed, accordingly, a block or the like is placed in the water tank so that a capacity of water stored in the water tank is reduced. In this case, the amount of water discharged is a little decreased, but the entire water stored in the water tank is discharged irrespective of the urination and defecation, thereby still causing a big problem in the water consumption for treatments after the urination and defecation.
- So as to solve the above-mentioned problems, an improved toilet bowl is disclosed in Korean Patent Laid-Open Publication No.
10-2010-0095110 (Dated March 30, 2010 - According to the improved toilet bowl, a pair of buttons disposed on an external surface of the water tank is selectively manipulated so that about 6 to 7 ℓ of water stored in the water tank is discharged after defecation and about 3.0 to 4.0 ℓ of water stored in the water tank is discharged after urination, thereby saving the amount of water consumed when compared with the general toilet bowl.
- On the other hand, traps are formed along a discharge passage formed on the inner lower portion of the body of the toilet bowl and are always filled with air. When waste and water are discharged through the discharge passage, however, discharge interference may occur seriously by the air filled in the traps, thereby failing to gently discharge the waste and water. Even in the case of the improved toilet bowl, if an amount of water discharged to the body is set to equal or less than a given level, that is, to 3.0 to 4.0 ℓ of water after urination and to 6 to 7 ℓ of water after defecation, it is hard to discharge the waste and water through the discharge passage, thereby failing to save the water anymore.
- Many endeavors have been made in this field to develop a novel water-saving toilet bowl that is capable of differently adjusts amounts of water discharged to a body from a water tank according to urination and defecation and that is capable of minimizing discharge interference caused by the air filled in traps to allow the waste and water in the interior of the body to be gently discharged, but up to now, no satisfying effects are obtained from the existing toilet bowls.
- Accordingly, the present invention has been made in view of the above-mentioned problems occurring in the prior art, and it is an object of the present invention to provide a water-saving toilet bowl that is capable of reducing an amount of water discharged therefrom, thereby avoiding a water consumption problem of a general toilet bowl caused by discharging the entire water stored in a water tank to a body after urination and defecation.
- It is another object of the present invention to provide a water-saving toilet bowl that is capable of reducing an amount of water discharged therefrom, thereby avoiding a water consumption problem of a general toilet bowl caused by setting an amount of water discharged to a body to equal or more than a given level by means of discharge interference caused by the air filled in traps of a discharge passage when waste and water are discharged through the discharge passage so that it is impossible to save the water anymore.
- To accomplish the above-mentioned object, according to the present invention, there is provided a water-saving toilet bowl including: a body for supporting a user in a state sitting thereon and for receiving waste at the time of urination and defecation; a water tank disposed on one side of the body to store water for washing the interior of the body at an internal space thereof; an auxiliary water tank mounted in the water tank to receive a portion of the water stored in the water tank and a portion of air in the body flowing when the waste and water are discharged from the interior of the body; and a water discharge adjustor mounted in the auxiliary water tank to differently adjust amounts of water discharged to the interior of the body according to the urination and defecation.

water tank 20 has awater inlet pipe 22 located at the inside thereof in such a manner as to be connected to an outside water pipe (not shown). - As the
water tank 20 is provided with thewater inlet pipe 22, accordingly, tap water is introduced through thewater inlet pipe 22 so that the water can be stored in thewater tank 20. - At this time, the
water inlet pipe 22 is open and closed by an operatingshaft 23 having afloat 23a ascended and descended according to changes in a water level of thewater tank 20. - As the
water inlet pipe 22 is open and closed by the operation of the operatingshaft 23, water supply is automatically carried out when the water level of thewater tank 20 is low, and water supply is automatically blocked when the water level of thewater tank 20 is high. - Further, the
water tank 20 has a throughhole 24 formed on the bottom thereof in such a manner as to communicate with the internal space of thebody 10. - As the
water tank 20 is provided with the throughhole 24, accordingly, the water in thewater tank 20 is discharged to thebody 10 when the throughhole 24 is open. - On the other hand, the
water tank 20 of the present invention has the same configuration as a water tank of a general toilet bowl, and accordingly, an explanation on the detailed structure of thewater tank 20 will be avoided. - The
auxiliary water tank 30 is mounted in thewater tank 20 and receives a portion of the water stored in thewater tank 20 and a portion of air in thebody 10 flowing when the waste and water are discharged from the interior of thebody 10. - At this time, the portion of air in the
body 10 is the air filled in thetraps 13a of thebody 10. - As shown in
FIGS.3 and4 , theauxiliary water tank 30 includes a lower body 30' fixedly located on the bottom surface of thewater tank 20 and anupper body 30" coupled to the lower body 30'. - In this case, the lower body 30' has a
water inlet hole 31 formed on the bottom surface thereof to introduce water thereinto. - As the lower body 30' is provided with the
water inlet hole 31, accordingly, the water in thewater tank 20 is introduced into the lower body 30' so that a portion of water in thewater tank 20 is stored in theauxiliary water tank 30. - At this time, the
water inlet hole 31 is formed on a steppedportion 32 of the lower body 30' spaced apart from the bottom of thewater tank 20. - As the
water inlet hole 31 is formed on the steppedportion 32, accordingly, the underside end periphery of thewater inlet hole 31 is open to introduce a portion of water in thewater tank 20 into theauxiliary water tank 30 therethrough. - Further, the lower body 30' has a
water outlet hole 33 formed on the bottom surface thereof in such a manner as to face the throughhole 24 of thewater tank 20. - As the lower body 30' is provided with the
water outlet hole 33, accordingly, the water in theauxiliary water tank 30 flows into thebody 10 through the throughhole 24 when thewater outlet hole 33 is open. - At this time, the
water outlet hole 33 has asupport piece 33a. - As the
water outlet hole 33 is provided with thesupport piece 33a, accordingly, thesupport piece 33a is mounted over the throughhole 24 to allow the lower body 30' to be fixed to thewater tank 20. - In this case, the
support piece 33a is spirally coupled to ascrew 33b. - As the
support piece 33a is spirally coupled to thescrew 33b, accordingly, thesupport piece 33a mounted over the throughhole 24 is ascended or descended as it rotates along thescrew 33b, and thesupport piece 33a can be ascended to the maximum so that thesupport piece 33a is brought into rigid contact with the throughhole 24. - Further, the lower body 30' has an
air flow pipe 34 located on top thereof in such a manner as to communicate with thedischarge passage 13 of thebody 10. - As the lower body 30' is provided with the
air flow pipe 34, accordingly, a negative pressure is formed in thedischarge passage 13 of thebody 10 when the air in thetraps 13a is introduced into theair flow pipe 34, so that the waste and water in thebody 10 are sucked into thedischarge passage 13 by means of the negative pressure allowing the water to be discharged gently. - At this time, the lower end periphery of the
air flow pipe 34 and thedischarge passage 13 are connected to each other by means of a separate connection pipe (having no reference numeral in the drawing). - Further, the
air flow pipe 34 has anexpansion member 34a disposed on top thereof. - As the
air flow pipe 34 is provided with theexpansion member 34a, accordingly, the amount of air introduced into theair flow pipe 34 is increased by means of the expansion of theexpansion member 34a. - In this case, the
expansion member 34a has avalve 34b automatically open when an internal pressure of theair flow pipe 34 is over an allowable pressure. - As the
expansion member 34a is provided with thevalve 34b, accordingly, the damages of theair flow pipe 34 and theexpansion member 34a caused by the excessive increment of the internal pressure of theair flow pipe 34 are prevented. - On the other hand, only if the
expansion member 34a is expandable through the air introduction into theair flow pipe 34, it may have all structures and shapes, and for example, theexpansion member 34a is made of a soft thin film. - Further, only if the
valve 34b is automatically open when the internal pressure of theair flow pipe 34 is over the allowable pressure, it may have all structures and shapes, and accordingly, the detailed explanation will be avoided. - The
upper body 30" has a recessedportion 35 formed on one side of top thereof. - As the
upper body 30" is provided with the recessedportion 35, accordingly, acleaning agent 50 is mounted at the recessedportion 35, as shown inFIG.8 , so that cleaning ingredients of thecleaning agent 50 are contained in the water discharged to thebody 10 from theauxiliary water tank 30, thereby performing cleaning for the interior of thebody 10 gently. - At this time, the recessed
portion 35 has anopen slot 35a formed on one side thereof in a longitudinal direction thereof. - As the recessed
portion 35 is provided with theopen slot 35a, accordingly, it is possible to introduce water into the recessedportion 35 through theopen slot 35a even in a relatively low water level where a level of water stored in theauxiliary water tank 30 does not reach top of the recessedportion 35, so that the cleaning ingredients of thecleaning agent 50 are contained easily in the water in theauxiliary water tank 30. - Further, the internal space of the
upper body 30" is divided by means of a partition wall (having no reference numeral in the drawing) formed in a longitudinal direction thereof, and one side space divided has a bottom (having no reference numeral in the drawing) on which an open hole (having no reference numeral in the drawing) is formed. - As one side internal space divided of the
upper body 30" is provided with the bottom having the open hole, accordingly, thewater discharge adjustor 40 is mounted on the bottom. - At this time, the bottom of the
upper body 30" has anextension pipe 36 extended downwardly therefrom. - As the bottom of the
upper body 30" is provided with theextension pipe 36, accordingly, water is introduced through theextension pipe 36 so that the water is stored in the internal space of theupper body 30" in which thewater discharge adjustor 40 is mounted. - On the other hand, only if the
upper body 30" and the lower body 30' are rigidly coupled to each other, they may be coupled to each other through various typical coupling methods, and for example, they may be engaged with each other by means of protrusion and groove. - The
water discharge adjustor 40 is mounted in theauxiliary water tank 30 and differently adjusts amounts of water discharged to the interior of thebody 10 according to urination and defecation. - The
water discharge adjustor 40 discharges 1.5 to 2.0fof water in the whole water stored in theauxiliary water tank 30 after urination and discharges 3.0 to 4.0 ℓ of entire water stored in theauxiliary water tank 30 after defecation, so that the water-saving toilet bowl according to the present invention has a remarkably smaller amount of water consumed after the urination and defecation when compared with the conventional toilet bowls. - On the other hand, the
water discharge adjustor 40 includes: a circular pipe-shapedhousing 41; a pair ofpush plates 42 located on an inner upper portion of thehousing 41; aconnection rod 43 ascended and descended according to the pressurization of thepush plates 42; a waterdischarge blocking plate 44 coupled to the lower end periphery of theconnection rod 43 in such a manner as to be inserted into the inside of thehousing 41 from the outside of thehousing 41 by means of the ascending movement of theconnection rod 43 to open the throughhole 24 of thewater tank 20; and afloat 45 ascended and descended according to the changes in a water level in thehousing 41. - At this time, the
housing 41 is open on a portion of the outer peripheral surface thereof to introduce water thereinto. - Further, the
push plates 42 are disposed just underside thebuttons 21 of thewater tank 20 in such a manner as to be pressurized by the contact with thebuttons 21. - Now, an explanation on the reduction in the water consumption through the water-saving toilet bowl according to the present invention will be in detail given.
- The
water tank 20 has thewater inlet pipe 22 located at the inside thereof in such a manner as to be connected to the outside water pipe, and accordingly, tap water is introduced through thewater inlet pipe 22, so that the water is stored in thewater tank 20. - Further, the
auxiliary water tank 30 is mounted in thewater tank 20, and as shown inFIG.5 , theauxiliary water tank 30 has thewater inlet hole 31 adapted to introduce water in thewater tank 20 thereinto, so that a portion of water in thewater tank 20 is stored in theauxiliary water tank 30. - At this time, the
water discharge adjustor 40 is mounted in theauxiliary water tank 30, and as mentioned above, thewater discharge adjustor 40 includes: the circular pipe-shapedhousing 41; the pair ofpush plates 42 located on an inner upper portion of thehousing 41; theconnection rod 43 ascended and descended according to the pressurization of thepush plates 42; the waterdischarge blocking plate 44 coupled to the lower end periphery of theconnection rod 43 in such a manner as to be inserted into the inside of thehousing 41 from the outside of thehousing 41 by means of the ascending movement of theconnection rod 43 to open the throughhole 24 of thewater tank 20; and thefloat 45 ascended and descended according to the changes in a water level in thehousing 41. - If the
buttons 21 disposed on the external surface of thewater tank 20 are manipulated after urination and defecation, thepush plates 42 are pressurized to allow theconnection rod 43 to be ascended, and as theconnection rod 43 is ascended, accordingly, the waterdischarge blocking plate 44 coupled to theconnection rod 43 is inserted into the inside of thehousing 41 from the state protruding outwardly from thehousing 41, so that the throughhole 24 formed on the bottom of thewater tank 20 in such a manner as to be blocked by the waterdischarge blocking plate 44 is open as shown inFIG.9 to allow water to be discharged from theauxiliary water tank 30 to the interior of thebody 10. Accordingly, the interior of thebody 10 is washed by the water, and together with the water, the waste received in the interior of thebody 10 is discharged to thedischarge passage 13 through theopening 12 formed on the inner lower portion of thebody 10, thereby perfectly performing the treatments after the urination and defecation. - At this time, the
water discharge adjustor 40 differently adjusts the amounts of water discharged to the interior of thebody 10 according to the urination and defecation. - In more detail, the
water discharge adjustor 40 differently adjusts the amount of water discharged when one of thepush plates 42 is pressurized by the manipulation of one of the pair ofbuttons 21 disposed on thewater tank 20 and the amount of water discharged when theother push plate 42 is pressurized by the manipulation of theother button 21 disposed on thewater tank 20. - After urination, accordingly, one of the
buttons 21 is manipulated to discharge a relatively small amount of water (1.5 to 2.0 ℓ of water), and after defecation, theother button 21 is manipulated to discharge a relatively large amount of water (3.0 to 4.0 ℓ of water), thereby minimizing the amounts of water consumed after the urination and defecation. - However, air is filled in the
traps 13a of thedischarge passage 13 of thebody 10, and when the waste and water are discharged, accordingly, discharge interference may occur by the air, so that if a relatively smaller amount of water (1.5 to 2.0 ℓ of water) than that in a general toilet bowl is discharged after urination or if a relatively smaller amount of water (3.0 to 4.0 ℓ of water) than that in a general toilet bowl is discharged after defecation, the water is not discharged gently by means of the discharge interference caused by the air, thereby making it hard to perform the treatments after the urination and defecation. - According to the present invention, however, the
auxiliary water tank 30 has theair flow pipe 34 communicating with thedischarge passage 13 of thebody 10, so that when the waste and water flow along thedischarge passage 13, as shown inFIG.6 , a portion of air in the interiors of thetraps 13a is accommodated in theair flow pipe 34, and a portion of thedischarge passage 13 is empty to form a negative pressure therein. Through the formation of the negative pressure, accordingly, the waste and water are sucked to thedischarge passage 13, and even if a relatively small amount of water is discharged to thebody 10 from theauxiliary water tank 30, the treatments after the urination and defecation are easily carried out. - At this time, the
air flow pipe 34 has theexpansion member 34a disposed on top thereof, and through the expansion of theexpansion member 34a, as shown inFIG.7 , an amount of air introduced into theair flow pipe 34 is increased so that the negative pressure formed in thedischarge passage 13 becomes stronger, thereby allowing the waste and water to be discharged gently. - As described above, the water-saving toilet bowl A according to the present invention includes the
water discharge adjustor 40 differently adjusts the amounts of water discharged to the interior of thebody 10 according to the urination and defecation, so that an amount of water discharged after urination is smaller than that after defecation, thereby saving the amount of water consumed. Further, the water-saving toilet bowl A according to the present invention includes theauxiliary water tank 30 in which a portion of water stored in thewater tank 20 is accommodated, so that when water is discharged by thewater discharge adjustor 40, the stored water in theauxiliary water tank 30, not the entire water stored in thewater tank 20, is discharged, thereby allowing thebody 10 to be washed with a relatively small amount of water to save the amount of water consumed after the urination and defecation. Furthermore, the water-saving toilet bowl A according to the present invention includes theauxiliary water tank 30 in which a portion of air in thebody 10 flowing when the waste and water are discharged from the interior of thebody 10 is accommodated, so that the negative pressure is formed in thedischarge passage 13 to allow the waste and water to be discharged gently, and the treatments after the urination and defecation are carried out even with a relatively small amount of water, thereby saving the amounts of water consumed after the urination and defecation. - While the present invention has been described with reference to the particular illustrative embodiments, it is not to be restricted by the embodiments but only by the appended claims. It is to be appreciated that those skilled in the art can change or modify the embodiments without departing from the scope and spirit of the present invention.
