The present invention relates to a sewage discharge apparatus of a variable water-saving toilet, and more particularly, to a sewage discharge apparatus of a variable water-saving toilet in which a part of directly supplied water is branched from a straight water supply path, and when the directly supplied water stored in an auxiliary tank formed at an outer periphery of a sewage discharge pipe of the toilet reaches a predetermined amount or more, sewage in a toilet bowl is discharged to the outside by a load of the auxiliary tank.
Description
Technical Field
The present invention relates to a sewage discharge apparatus of a variable water-saving toilet, and more particularly, to a sewage discharge apparatus of a variable water-saving toilet in which a part of directly supplied water is branched from a straight water supply path, and when the directly supplied water stored in an auxiliary tank formed at an outer periphery of a sewage discharge pipe of the toilet reaches a predetermined amount or more, sewage in a toilet bowl is discharged to the outside by a load of the auxiliary tank.
Background
In general, a toilet bowl uses a siphon (sipon) principle in which a predetermined amount of water is stored in the toilet bowl for smooth washing of foul odor discharged from a waste discharge port or waste.
The siphon principle is a principle in which water is stopped when the water level in the inverted U-shaped pipe and the water level in the toilet pan are balanced, and conversely, if the water level in the toilet pan is suddenly increased, the water in the toilet pan is discharged by a pressure difference of the siphon tube in a relatively low pressure state along with a rise in the pressure in the toilet pan.
As shown in fig. 1, a general toilet stool includes: a bowl 2(bowl) filled with a predetermined amount of water; and a water storage tank 1 which stores a predetermined amount of flushing water at a position higher than the tub 2, and which is connected to the tub 2 through a supply path 2a closed by a water supply port packing 5, and which rapidly supplies water from the water storage tank 1 to the tub 2 through the supply path 2a by opening a water supply port 10 by the water supply port packing 5 interlocked with the water discharge rod 3 through operation of a water discharge rod 3 provided in the water storage tank, whereby, as the water level in the tub 2 increases, stool and urine deposited in the tub are discharged through a discharge trap 2c by a siphon effect generated by the water pressure generated in the tub 2 and the water discharged along the discharge path 2b of the tub by the water pressure.
However, the conventional toilet described above has a problem that a water level higher than the height of the drain trap 2c for preventing reverse flow of bad odor or the like needs to be maintained in the toilet bowl at all times, and a water amount higher than the water pressure of the drain trap 2c needs to be used when flushing, and therefore, a large amount of water is consumed.
Further, in the conventional toilet bowl, the diameter of the bowl discharge tank is 45mm or more, that is, generally about 45-55mm, determined by KS specification for smoothly discharging the waste water, and a siphon phenomenon is required to be generated for cleaning by suction force in order to clean the waste in the bowl, and it is necessary to supply water of 60mm or more to the inside of the bowl in the shortest time in order to generate such a siphon phenomenon.
Therefore, in the conventional toilet bowl, even if water is supplied into the bowl through the direct water supply path of the water pipe having a diameter of about 15mm, the siphon phenomenon cannot occur because the diameter of the bowl discharge pipe is generally about 45 to 55mm, and the water is directly discharged through the bowl discharge pipe, so that the inside of the bowl cannot be cleaned.
Therefore, in the case of a conventional male urinal, it is common to use a water pipe for direct connection and perform automatic cleaning by a detector or the like, but in the case of a toilet bowl, for the above reasons, it is impossible to clean waste by direct connection of the water pipe, and an automatic toilet bowl cannot be widely used.
Meanwhile, the conventional toilet (a toilet with a wash valve having a water supply caliber of 1 inch except a part thereof) must have a sink function to be washed, and thus cannot be reduced in size due to design restrictions and sinks, thereby being restricted in space. Further, when a toilet bowl (also called a one-piece toilet bowl) is manufactured by integrating the sink and the base, the yield of production is reduced due to an increase in the fraction defective, resulting in an increase in cost.
Meanwhile, water leakage occurs due to a defect of a water supply pipe arranged inside the water tank, and it is difficult for a user to simply detect the water leakage, so that the user can be aware of the water leakage after checking water and sewage charges. Further, in the case of a toilet bowl used in public places such as public toilets or office buildings, since there is no water tank, a pipe having a diameter of 25mm (1 inch) is separately provided from a general 15mm water pipe so as to supply a large amount of water in a short time for use by direct water supply, and thus enormous equipment costs are required.
Meanwhile, the variable double straight pipe of the variable double straight pipe type water saving toilet, korean patent No. 10-1131810, is operated by means of a conventional water supply flow path and a rim of a tub, and when the water pipe supplies the straight water supply, if a water level inside the tub rises, the variable straight pipe goes down to discharge the filth, and a water pipe pressure is sharply decreased in a water path leading to the inside of the sink and the tub and a water path inside the rim of the tub, and as a result, the water pipe pressure cannot be used, thereby causing a problem in washing the filth inside the tub, and when the filth is discharged, it is difficult to adjust a downward extension time of the variable straight pipe, thereby causing a reverse flow of a part of the filth in some cases.
Meanwhile, the variable double straight pipe of the variable double straight pipe type water saving toilet, korean patent No. 10-1131810, requires the supply of the straight supply water to the tub until the variable double straight pipe for discharging the sewage descends, and the supplied straight supply water is directly mixed with the sewage stored in the tub, so that the supplied straight supply water also becomes the sewage, and as a result, the washing water will be wasted, and the water saving effect will be halved.
Meanwhile, in the variable double linear pipe of the variable double linear pipe type water saving toilet of korean patent No. 10-1131810, a part of the sewage discharge water is used as the water of the auxiliary tank at the outer periphery of the sewage discharge pipe, and thus, after a predetermined period of time, a clogging phenomenon occurs due to the sewage flowing into the auxiliary tank, and a durability problem occurs in which the discharge unit is operated erroneously due to malfunction of the sewage discharge pipe.

Detailed Description
Hereinafter, a sewage discharge apparatus of a variable water-saving toilet according to the present invention will be described with reference to the accompanying drawings.
Fig. 2 and 3 are views illustrating a state before discharging sewage of the sewage discharging apparatus of the variable water saving toilet stool of the present invention. Fig. 4 and 5 are views illustrating a state of discharging sewage of the sewage discharging apparatus of the variable water saving toilet stool of the present invention. Fig. 6 and 7 are exploded perspective views illustrating a connection state of a sewage discharge pipe and an elastic part of a sewage discharge apparatus of a variable water saving toilet stool according to the present invention.
Referring to fig. 2 and 4, the direct water supply type water saving toilet of the present invention generally includes a toilet body 100, a bellows 200, a direct water supply diverging part 300, a sewage discharging pipe 400, and an elastic part 500.
The above respective structures are explained.
The toilet body part 100 of the present invention is installed on the floor or wall of a toilet.
The toilet body 100 has a straight water inlet 111 through which straight water flows from the outside through the straight water passage 101, and a bowl 110 having an upper opening and storing a predetermined amount of sewage. The tub 110 is cleaned by supplying the direct water to the tub 110 through the direct water inlet 111. When the valve is opened by a water stop valve (not shown), the straight water flows into the straight water flow path 101 to be involved in the cleaning of the toilet bowl 110.
Also, the toilet body part 100 includes a connection pipe 120 for discharging the wash water from the bowl 110.
The toilet body 100 includes a cover 140 covering a rear side of the bowl 110 and guiding the floor pipe 130 for discharging the filth discharged through the connection pipe 120 to an outside of the toilet.
The bellows 200 of the present invention is connected to the connection pipe 120. That is, one end of the bellows 200 is connected to an end of the connection pipe 120.
One end of the bellows 200 may be inserted into the connection pipe 120 and fixed, or may be connected by screwing.
The bellows 200 may form a flow path of the sewage discharged from the tub 110, and may be bent in one direction by an external force as a flexible tube.
Direct water supply and diversion part 300
The direct water supply diverging part 300 according to the present invention is connected to the direct water supply passage 101, and diverts a part of the direct water supply from the direct water supply passage 101 when the direct water supply flows into the tub 110. When the direct water for washing the tub 110 is supplied to the tub 110, a part of the direct water branched from the direct water flow path 101 by the direct water branching unit 300 flows into and is stored in an auxiliary tank 420 of the sewage discharge pipe 400, which will be described later, and the sewage discharge pipe 400 is rotated by the self weight of the auxiliary tank 420 to participate in the discharge of the sewage through the sewage discharge pipe 400.
The direct water supply and diversion unit 300 includes a diversion bellows 310 and a diversion water inflow unit 320.
The upper portion of the branch bellows 310 is coupled to the straight water supply passage 101, and the lower portion thereof is connected to the upper portion of the sub tank 420.
The branched water inflow portion 320 is connected to an upper portion of the branched bellows 310, is disposed in the straight water supply channel 101, and allows a branched water, which is a part of the straight water, to flow therein, and the branched water flows into the auxiliary tank 420 of the sewage discharge pipe 400, which will be described later, through the branched bellows 310 and is stored therein.
With the direct supply of water directly supplied from the tap water pipe of the embodiment of the present invention, the sewage contained in the bowl 110 of the toilet can be discharged even without the sink.
Meanwhile, it is preferable that an offensive odor prevention sheet 321 is further formed at an inlet portion of the branched water inflow portion 320, and the offensive odor prevention sheet 321 is opened by water pressure when the direct water is supplied to the direct water supply path 101 and closed by its own weight when the direct water is blocked, thereby preventing the offensive odor from flowing into the direct water supply path 101.
When the malodor prevention sheet 321 is provided, since the direct water supply is blocked, the malodor is blocked by its own weight, and the malodor flows into the tub 110 through the direct water supply path 101, thereby preventing the malodor from flowing into the toilet.
Fig. 5 is a front view showing a sewage drain pipe of the present invention.
Referring to fig. 2 to 5, the sewage discharge pipe 400 according to the present invention is connected to the corrugated pipe 200, and when the straight-water supplied through the straight-water distribution portion 300 is stored in the auxiliary tank 420, a load is applied to the sewage discharge pipe 400 to direct the sewage discharge pipe 400 downward, thereby discharging the sewage to the outside.
The above-mentioned sewage discharge pipe 400 includes: a main discharge pipe 410 connected to an end of the corrugated pipe 200 and having a cylindrical shape; and an auxiliary tank 420 provided at an outer circumference of the main exhaust pipe 410 to surround the outer circumference of the main exhaust pipe 410.
The main discharge pipe 410 is connected to the corrugated pipe 200 to discharge sewage.
The auxiliary tank 420 includes an auxiliary discharge hole 422 provided at an outer circumference of the main discharge pipe 410, and supplies and stores the direct supply water branched from the direct supply water branching part 300 to discharge the direct supply water stored at a lower portion. In the auxiliary tank 420, when the straight supply water for washing the tub 110 is supplied to the tub 110, the straight supply water branched from the straight supply water branching part 300 is supplied and stored, and the sewage discharge pipe 400 is rotated by the self weight of the stored straight supply water so that the sewage can be discharged to the outside through the main discharge pipe 410 connected to the bellows 200. In this case, when the amount of the straight supply water branched from the straight supply water branching part 300 reaches a set amount, the straight supply water in the auxiliary tank 420 is rotated downward by its own weight to discharge the sewage to the outside through the main discharge pipe 410, and the discharge time of the sewage discharged through the main discharge pipe 410 is extended by the speed at which the straight supply water supplied to the auxiliary tank 420 is discharged to the auxiliary discharge hole 422.
A connection part 421 connected to the branch bellows 310 of the straight supply water branch part 300 is provided at an upper part of the auxiliary tank 420, and an auxiliary discharge hole 422 for discharging the stored straight supply water is formed at a lower peripheral part of the auxiliary tank 420.
Referring to the above-described structure, the sewage discharge pipe 400 maintains an upright state without discharging sewage. That is, if the direct water does not flow into the direct water supply diverging part 300, the sewage discharge pipe 400 does not rotate, and thus the tub 110 maintains a stable water storage amount, and the adhesion of the filth or the generation of the bad smell inside the tub 110 can be suppressed.
Then, when the water stop valve or the lever is operated to supply the direct water to the direct water supply flow path 101 after the user's convenience, a part of the direct water is branched from the direct water supply flow path 101 by the direct water supply branching unit 300 and stored in the auxiliary tank 420 of the sewage discharge pipe 400.
In the state of fig. 2 and 3, when the amount of the straight supply water branched from the straight supply water branching portion 300 reaches a set amount, the sewage discharge pipe 400 is rotated downward by its own weight in the state of fig. 4 and 5. As shown in fig. 4 and 5, the sewage discharge pipe 400 is rotated in a state where the main discharge pipe 410 can discharge sewage from the tub 110 formed horizontally.
The straight water stored in the auxiliary tank 420 of the sewage discharge pipe 400 becomes power for rotating the main discharge pipe 410 downward due to its weight, and plays an important role in extending the discharge time.
As described above, if the sewage discharge pipe 400 is rotated downward, the sewage stored in the tub 110 passes through the corrugated pipe 200 and is discharged to the outside through the main discharge pipe 410 of the sewage discharge pipe 400. In this case, the straight supply water branched and stored in the sub-tank 420 is slowly discharged to the outside through the sub-discharge hole 422 along the lower direction.
Meanwhile, the straight supply water flows into the tub 110 through the straight supply water flow path 101 and the straight supply water inlet 111 to wash the tub 110, and the washed sewage is also discharged to the outside through the main discharge pipe 410 of the sewage discharge pipe 400 through the bellows 200.
The straight feed water passes through the straight feed water flow path 101 and flows into the tub 110 through the straight feed water inlet 111 slightly slower than the straight feed water branched by the straight feed water branching portion 300, and thus flows into the tub 110 slightly slower than the rotation of the sewage for discharging the sewage discharge pipe 400 or almost simultaneously with the straight feed water. As described above, if the straight feed water is supplied to the tub 110 at a time slightly slower than the sewage discharge time through the sewage discharge pipe 400 or almost at the same time, the straight feed water supplied to the tub 110 is not mixed with the sewage but washes the tub 110, and therefore, the straight feed water supplied to the tub 110 participates only in the washing of the tub 110. As described above, the direct water supplied to the tub 110 participates only in the washing of the tub 110, and thus, the direct water supplied to the tub 110 is mixed with the sewage stored in the tub 110 and overflows, so that the clean state of the tub 110 can be maintained and the water saving effect can be exerted.
When the straight supply water branched and stored in the sub-tank 420 is discharged to a predetermined amount through the sub-discharge hole 422, the sewage discharge pipe 400 returns to the home position by the elastic force of the elastic part 500, and thus, the state of fig. 2 and 3 is obtained. Since the rotation state of the sewage discharge pipe 400 is maintained until the straight supply water discharged from the auxiliary tank 420 of the sewage discharge pipe 400 through the auxiliary discharge hole 422 is completely discharged, the sewage discharge time through the main discharge pipe 410 of the sewage discharge pipe 400 can be extended. As described above, the time for discharging the contaminated water through the main discharge pipe 410 is extended, whereby the contaminated water is completely discharged, thereby increasing the efficiency of cleaning.
The adjustment of the discharge time of the contaminated water discharged through the main discharge pipe 410 of the contaminated water discharge pipe 400 is related to the increase or decrease of the discharge speed of the straight supply water supplied to the auxiliary tank 420 through the auxiliary discharge holes 422, and as a result, the increase or decrease of the size of the auxiliary discharge holes 422.
The sewage discharge time of the main discharge pipe 410 can be adjusted by varying and adjusting the hole area of the auxiliary discharge hole 422 formed at the rear end of the auxiliary tank 420.
As shown in fig. 2 and 3, when the sewage discharge pipe 400 returns to the home position, the washing water in the tub 110 is prevented from being discharged. In this case, the time point when the sewage discharge pipe 400 returns to the home position is the last time period for supplying the straight water supply to the straight water supply flow path 101, and the straight water supply is supplied only to the tub 110 in the last time period for supplying the straight water supply to the straight water supply flow path 101, so that the tub 110 is in a state of containing about half of the straight water supply.
Fig. 6 and 7 are exploded perspective views illustrating a linked state of a sewage discharge pipe and an elastic part of a sewage discharge apparatus of a variable water saving toilet stool according to the present invention.
Referring to fig. 6 and 7, the elastic part 500 of the present invention elastically connects the connection pipe 120 and the sewage discharge pipe 400, and has an elastic force for making the sewage discharge pipe 400 stand when the direct water supply is blocked.
Preferably, the weight of the straight supply water supplied to and stored in the auxiliary tank 420 is greater than the elastic force of the elastic part 500, and the sewage drain pipe 400 is rotated by the weight of the straight supply water stored in the auxiliary tank 420.
The elastic part 500 includes: a first locking member 510 protruding along both sides at a connection portion 115 for connecting the connection pipe 120 and the bellows 200, and having first locking holes 511 formed at both end portions; a pair of second locking members 520 provided on both sides of the sewage discharge pipe 400 and having a plurality of second locking holes 521 formed at intervals; and a pair of elastic members 530 having one end connected to one of the second locking holes 521 of the pair of second locking members 520 and the other end connected to the first locking hole 511.
The first locking holes 511 of the first locking member 510 are formed in a plurality at predetermined intervals at both ends of the first locking member 510.
The reason why the plurality of first locking holes 511 and the plurality of second locking holes 521 are formed is to adjust the tension of the elastic member 530.
The pair of second locking members 520 are formed in a plate shape and protrude from both side ends of the main discharge pipe 410.
Preferably, the connection part 115 for connecting the connection pipe 120 and the bellows 200 includes a first connection part 115a connected to the connection pipe 120 and a second connection part 115b connected to the bellows 200, so that the first connection part 115a is combined with the second connection part 115 b.
Referring to fig. 2 to 5, the malodor prevention unit 600 according to the present invention is disposed inside the sewage discharge pipe 400, and is opened by the flow of the sewage when the sewage flows, and is closed when the sewage does not flow.
The malodor preventing part 600 includes a malodor preventing member 610, and the malodor preventing member 610 is disposed inside the sewage drain pipe 400, has a hollow shape, and is formed of a flexible plastic or an exploded rubber.
Preferably, the malodor preventing part 610 is formed of plastic or rubber formed to be hollow and having flexibility.
Wherein one end of the malodor preventing member 610 is fixed to the inner circumference of the sewage drain pipe 400. The above-described fixing means may be realized using an adhesive.
The other end of the malodor preventing member 610 forms a free end along the other end side of the inner circumference of the sewage drain pipe 400. That is, the other end of the malodor preventing member 610 is not fixed inside the sewage drain pipe 400.
Accordingly, when the sewage stored in the tub 110 flows to the bellows 200 through the connection pipe 120, the flowing sewage flows into the hollow of the malodor prevention member 610 to open the malodor prevention member 610.
In this case, the circumference of the malodor prevention member 610 is smaller than the outer circumference of the sewage drain pipe, and thus, may be closely attached to the sewage drain pipe 400.
When the sewage flows completely through the sewage discharge pipe 400, the other end of the malodor prevention member 610 disposed as a free end changes its shape so as to be closely attached to the sewage discharge pipe 400.
That is, after all the sewage is discharged, the other end of the malodor prevention member 610 is closely attached to the sewage discharge pipe 400 and is closed.
Accordingly, the other end of the malodor prevention member 610 is in a state of being closed to some extent, and thereby, the malodor from the side of discharging the contaminated water can be minimized from flowing backward to the tub 110 side.
The present invention is not limited to the above-described embodiments, but may be manufactured in various forms, and those skilled in the art to which the present invention pertains may implement the present invention in other specific forms without changing the technical idea or essential features of the present invention. Therefore, the above-described embodiments are illustrative embodiments in all respects, and are not intended to limit the present invention.
