Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a flushing apparatus,

The present invention includes an inner housing installed in a water tank of a straight-on type toilet seat for storing washing water separately so that the amount of washing water that can be installed in a general purpose in a straight-mouth type toilet bowl having various capacities can be minimized To a water dropping device of a direct-entry type toilet.

Generally, a toilet bowl provided in a toilet uses a siphon system in which a water tank containing a predetermined amount of water is provided behind a bowl, and the bowl is washed using wash water contained in the water tank through a lever operation after use .

Such a siphon system is most commonly used because it has a simple and easy-to-use structure of the flow path of a toilet.

However, the general siphon type toilet has a disadvantage in that a considerable amount of water is wasted because it is necessary to discharge all the washing water contained in the water tank in order to obtain strong discharge power according to the siphon effect when washing the toilet.

In order to reduce the waste of water, a method of saving the washing water used for cleaning the toilet by putting bricks or heavy and bulky objects in the water tank is used.

However, when the brick is placed in such a manner, the amount of water used can be reduced. However, since the discharge power of the washing water is decreased because the discharge power of the siphon type is proportional to the amount of stored water, the piping of the toilet can be unexpectedly blocked, It may not be cleaned at the same time.

In addition, if bricks or the like are inserted into the water tank of the toilet, there is a problem that the jetting hole of the toilet bowl is clogged due to the inflow of foreign matter, or moss is generated due to water contamination in the water tank.

Therefore, in order to increase the convenience of the user and to save the water used in the toilet, there is an increasing tendency to install the straight-on type toilet bowl which can solve the problems of the siphon method.

The piping structure of the general siphon type toilet bowl is composed of the pipe between the dirt discharge port and the toilet bowl body in the shape of "? "So that the washing water is discharged through the siphon effect,

The bearing portion 123 of the first elevating member 120A protrudes forward from the upper end of the lifting rod 120 and is received by the operating lever 110 pivoted through the lever through hole 122, (120) is raised.

The support part 123 can be any shape as long as it can easily receive the force by the operation lever 110. However, even if the user does not press the operation switch 37 a lot, The rod 120 should be raised.

Further, the stopper 124 of the first lifting body 120A is provided in a shape inclined downwardly to the lower rear side of the lever through-hole 122 and is engaged by the control unit 200 or released from the engagement operation .

When the lifting rod 120 is lifted up, the stopper 124 pushes up the support lever 210 (see FIG. 4) when the support lever 210 contacts the support lever 210 of the control unit 200, The support portion 210a of the support lever 210 is rotated upward to the original position after the lift of the lift rod 120 is completed and the stopper 124 is rotated in the downward direction, Is supported.

The shielding member 130 is sandwiched between the lifting rod 120 (more strictly, the first lifting body 120A) and the first lifting hole 223 of the control unit 200 is lifted up and down by the lifting rod 120, Or closes the inflow hole 311 of the discharge portion 300.

The upward and downward range of the shielding member 130 is between the first packing 120e of the lifting rod 120 provided below the stopper 124 and the step 121 of the adjusting bolt 120C, The substantial upward and downward range of the shielding member 130 is substantially the same as that between the first packing 120e and the upper end of the outer cylinder 310 of the discharge unit 300 do.

The side wall part is inserted into the inflow hole 311 between the outer cylinder 310 and the inner cylinder 340 of the discharge part 300 and the second packing 130a are provided to close the first lift hole 223 and the second lift hole 331 in accordance with the rising and falling.

That is, when the lifting rod 120 is lowered, the shielding member 130 is lowered by the first packing 120e so that the second packing 120a is formed in the inflow hole 311 formed between the outer cylinder 310 and the inner cylinder 340, The first packing 120a is brought into close contact with the second lift hole 331 of the shielding member 130 so that the discharge portion 300 is closed,

When the lifting rod 120 is lifted, the shielding member 130 is lifted by the step 121 and the first packing 120e is pressed by the first lifting hole 120c of the control body 220, (223) and closed.

Therefore, when the lifting rod 120 is lowered, the shielding member 130 closes the discharging unit 300, replenishing and storing the washing water in the storing unit S,

The first packing 120e closes the first lift hole 223 by the shielding member 130 so that the washing water discharged to the discharge portion 300 is discharged to the rim side pipe 34. [ It is possible to prevent the backflow to the control unit 200 and the sealing of the shielding member 130 and the lifting and lowering rod 120. Thus, it is possible to reduce the amount of washing used in the washing process.

The opening and closing member 140 is connected to the lower end of the second lifting body 120B of the lifting rod 120 and opens and closes the dirt discharging opening 31 in accordance with the lifting and lowering of the lifting rod 120. [

When the user lifts the operation switch 37 to raise the lifting rod 120, the closure member 140 rises to open the dirt outlet 31. When the lifting rod 120 descends due to its own weight, The member 140 is also lowered to close the dirt outlet 31. FIG.

The opening and closing member 140 and the second ascending and descending member 120B are respectively engaged with the hooks 140a and 120f to secure the fluidity of the opening and closing member 140, So that the opening and closing member 140 is closed in conformity with the shape of the opening and closing member 140.

The hooks 140a and 120f are formed to have clearances in the vertical direction, respectively, to improve the fluidity of the opening and closing member 140 when the opening and closing member 140 is lifted and lowered.

The opening and closing member 140 includes an outer tubular body 141 connected to the second lifting body 120B of the lifting rod 120 and having a lower opening,

An inner body 142 inserted into the lower opening so as to have an inner circumferential surface of the outer tubular body 141 and a spacing portion 140a and having a waste water discharge hole 140b communicated with the spacing portion 140a,

And a packing member 143 coupled to the lower end of the inner body 142 to contact the dirt outlet 31.

The center of the packing member 143 is provided with a hollow portion (not shown) communicating with the waste water discharge hole 140b.

When the inner body 142 is coupled to the outer tubular body 141 having the lower opening so as to have the spacing portion 140a, the washing water of the straight-on type toilet can be supplied to the separating portion 140a through the dust- 31 are closed to prevent the odor from flowing backward.

Particularly, through the structure of the separation part 140a and the waste water discharge hole 140b, there is an effect that the waste water discharged into the toilet bowl body 30 is discharged to the waste water discharge port 31 without the water drop operation of the straight water type toilet.

That is, in the case of a large rest room such as a restaurant or a rest area, cleaning and the like are performed, and the generated wastewater is discharged to the toilet body 30,

When the washing water in the water tank 33 is discharged downward every time the toilet water is discharged into the toilet bowl body 30, waste water is wasted. However,

The present invention eliminates the need for the water discharge operation for opening the waste discharge port 31 every time the waste water gets into the toilet bowl 30 even if a large amount of waste water is discarded since the abandoned waste water is naturally discharged. The use can be reduced.

The outer tubular body 141 and the inner body 142 are made of a plastic material, and the packing member 143 is preferably made of a rubber material having elasticity.

When the opening and closing member 140 closes the dirt outlet 31, the packing member 143 is closely contacted with the dirt outlet 31 and can be closed The opening and closing member 140 is preferably provided with a weight member 144 for increasing the load.

The weight member 144 may be made of a heavy weight of lead or iron material. In order to prevent problems such as rusting by contact with washing water, a ring-shaped weight member may be attached to the packing member 143) in a state in which they are inserted.

The control unit 200 supports the lifting rod 120 to discharge the washing water appropriately when the lifting rod 120 is lifted by the water lifting wire 20, So that water is replenished and stored in the storage unit S.

The control unit 200 includes a support lever 210, a control body 220, a buoy support 230, and an upper buoy 240.

 The support lever 210 is configured such that when the lift rod 120 is lifted up, the contact portion 210a is pushed rearward by the inclined surface of the stopper 124 to rotate downward about the hinge hole 222, So as not to interfere with the rise of the &

When the interference with the stopper 124 is released as the lifting rod 120 is continuously raised, the contact portion 210a returns to the front side and rotates upward about the hinge hole 222 to support the lower end of the stopper 124 Thereby preventing the lifting rod 120 from descending.

Since the lifting rod 120 can not receive the buoyant force and receives a force to be lowered by its own weight irrespective of the level of the washing water, the lifting rod 120 is maintained in the lifted state of the lifting rod 120 through the supporting lever 210 , The washing water can be discharged as much as necessary.

The support lever 210 contacts the stopper 124 of the lifting rod 120 and rotates downward to the rear side when the lifting rod 120 is lifted by lowering the operation switch 37 by the user, When the stopper 124 reaches the position higher than the support lever 210 and the contact is released, the support lever 210 rotates backward to the front side and returns to the home position to support the lower end of the stopper 124, So that the latching operation is performed.

To this end, the support lever 210 has a shape in which the inside is penetrated so that the lifting rod 120 can pass through, and both side ends of the contact portion 210a are hingedly fixed to the hinge hole 222 of the control body 220 And the front end of the control body 220 is inserted into the slit groove 230a of the buoy support base 230 so as to be movable forward and backward and a contact portion 210a is formed inside the portion fixed to the control body 220, (223) so as to support and support the stopper (124) of the lifting rod (120).

As the level of the wash water in the storage unit S (more strictly, inside the case 400) is lowered, when the buoy table support 230 is lowered, the support lever 210 rotates downward, The lifting rod 120 is lowered by its own weight so that the shielding member 130 closes the inflow hole 311 and the opening and closing member 140 closes the dust discharge port 31 to shut off the discharge of the washing water So that the washing water is stored in the storage unit S.

That is, if the support lever 210 continues to support the stopper 124, the lifting rod 120 is kept in a continuously raised state, and the inflow hole 311 and the dirt outlet 31 are opened. Thereby preventing the washing water in the storage section S from being continuously discharged.

The control body 220 has a first lift hole 223 formed at the center thereof and a hinge hole 221 to which the operation lever 110 is hinged is formed at the upper end of the rear support of the first lift hole 223, A hinge hole 222 to which the lever 210 is hinged is formed on the rear surface of the first lift hole 223 and guides the lift rod 120 moving up and down in the first lift hole 223.

Therefore, the operation lever 110 can be rotated so as not to interfere with the support lever 210 at a position higher than the support lever 210, and the lift rod 120 can be raised or lowered in the central portion of the control body 220 have.

At this time, a guide groove 224 is formed in the first lift hole 223 of the control body 220 so as to smoothly guide the lifting and lowering of the lifting rod 120. The guide groove 224 is formed in the lifting rod 120 The guide protrusions 125 may be formed to correspond to each other.

The upper portion of the float supporter 230 is inserted into the case through the coupling groove 241 of the upper float 240 and the lower end of the float supporter 230 is inserted into the insertion hole provided in the front surface of the first lift hole 223 of the control body 220 225 and has a slit groove 230a through which the support lever 210 is connected at the rear and moves up and down according to the rotation of the support lever 210 or the upward and downward movements of the upper buoy 240.

The depth of the fitting hole 225 is formed so as not to be detached when the float supporter 230 is lifted to the maximum height, thereby preventing the float of the flush water from being discharged due to malfunction due to disengagement of the float supporter 230.

The upper buoy 240 coupled with the buoy support table 230 is rotated downward while descending along with the buoy table support 230 as the water level of the storage portion S is discharged and the water level is lowered , The stopper 124 is released from the engagement operation, so that the elevation portion 100 is lowered and the dirt outlet 31 is closed.

That is, when the stopper 124 is supported through the latching operation of the support lever 210 and the washing water in the storage part S is discharged while the lifted state of the lifting part 100 is maintained, The buoy 240 and the buoy support 230 and the downward rotation of the support lever 210 result in the descent of the lifting rod 120 of the lifting part 100 to close the dirt outlet 31 .

The upper buoy 240 is raised and lowered by the buoyancy generated from the washing water in the storage portion S and is formed in an empty form so as not to be obstructed by the control body 220 or the lifting rod 120 And is preferably made of a plastic material capable of receiving sufficient buoyancy by the washing water of the storage part S.

At this time, the buoy support base 230 is formed in a concavo-convex shape on one side or both sides, and the upper buoy 240 is attached to the inner surface of the coupling groove 241 through which the buoy support base 230 passes, And a hook (not shown) is projected to engage the hook.

Since the height of the upper buoy 240 can be adjusted with respect to the buoy support 230 through the engagement of the concave and the convex and the hook, the amount of water to be discharged can be freely adjusted.

That is, when the upper buoy 240 is coupled to the upper end of the buoy support 230, the buoy support 230 coupled with the upper buoy 240 can be lowered The lever 210 is rotated to close the inflow hole 311 and the dirt outlet 31 along with the descent of the elevation part 100,

Conversely, when the upper buoy 240 is lowered to the lower end of the buoy support 230, the upper buoy 240 can be kept up by the buoyant force while the wash water level is sufficiently lowered,

The user can easily adjust the amount of washing water discharged according to needs.

This is because the washing water discharged through the water lowering device of the present invention is determined by the opening time of the inflow hole 311, that is, the rising up time of the lifting part 100, so that the height of the upper buoy 240 can be freely adjusted, The opening time of the inflow hole 311 is adjusted so that the discharged washing water can be adjusted and used.

For this purpose, it is more preferable that a scale is displayed on the front surface of the buoy support base 230.

Although not shown in the drawings, a bolt connection or the like may be further added to secure the upper buoy 240 and the buoy support 230.

The discharge unit 300 is formed at a lower portion of the storage unit S so that the control body 220 of the control unit 200 is coupled to the upper portion of the discharge unit 300. The washing water drained when the lift unit 100 rises is connected to the rim- 34).

The discharge portion 300 mainly includes an outer tube 310, an overflow tube 320, and an inner tube 340.

The outer cylinder 310 and the inner cylinder 340 are in the shape of a pipe having upper and lower portions opened,

The outer tube 310 is mounted on the drain port 32 of the water tank 33 and has a plurality of inlet holes 310a radially formed at the upper end protruding from the bottom of the storage unit S, The reason why the drainage holes 312 are shown in broken lines in the drawing is that the drainage holes 312 are not actually visible due to the sectional structure due to the inner tube 340) Respectively.

The inner cylinder 340 is coupled to the outer cylinder 310 so as to be spaced apart from each other to form an inflow hole 311 communicating with the rim side drain hole 312 at an upper end portion between the outer cylinder 310 and the inner cylinder 340.

The inflow hole 311 formed by separating the outer cylinder 310 and the inner cylinder 340 from each other is formed of vanes 310b provided at the lower end of the inner circumference of the outer cylinder 310 so that the inflow hole 310a- 311) and the drain hole 312 are communicated with each other.

Accordingly, when the shielding member 130 is lifted by the elevation of the lifting part 100, the inflow hole 311 is opened and the washing water in the storage part S flows into the inflow hole 311 through the inflow hole 310a , The washing water thus introduced is discharged to the rim side drain hole 312 and discharged to the toilet bowl main body 30 through the rim side pipe 34,

When the lifting part 100 descends and the dirt outlet 31 is closed through the release operation of the support lever 210, the discharged washing water is replenished and stored in the toilet bowl main body 30,

When the shielding member 130 is lowered as the water level of the washing water in the storage unit S is lowered, the inflow hole 311 is closed and the discharge of the washing water to the toilet bowl 30 is blocked, Is stored.

The outer tube 310 can be fixed to the bottom of the water tank 33, and the fixing method can be selected by suitably selecting a bolt connection, a rivet connection, or the like.

At this time, a packing 313 made of rubber or the like may be provided at the lower end of the outer cylinder 310 to prevent leakage of the washing water.

The overflow pipe 320 is formed at the bottom of the inner housing H and at one side of the outer cylinder 310.

The overflow pipe 320 is used to adjust the amount of wash water stored in the storage unit S and may be a general pipe shape and the height may be made different depending on the volume of the storage unit S of the inner housing H have.

The present invention may further include a case 400 that covers and protects the control unit 200 and the elevation unit 100 and is fixed to the storage unit S of the inner housing H. [

The case 400 may be in the form of a cylinder having a bottom opened, and includes a wire hole 410 and a washing water induction hole 420.

The wire hole 410 is formed at the upper end of the case 400 and the water descending wire 20 is passed,

The washing water induction hole 420 is formed on the side surface of the case 400 and allows the washing water to be introduced.

At least one of the wash water induction holes may be formed in the direction of the buoy support bases 230 so that the scale of the buoy support bases 230 may be formed by a user It is preferable to visually check the height of the upper buoy 240 so as to be adjustable.

Hereinafter, operations and effects of the water dropping device of the straight-mouth type toilet bowl having the above-described configuration will be described.

FIGS. 5A to 5F are side views illustrating the operation of the water dropping device of the straight-on type toilet bowl according to the present invention,

5A, when the user does not lower the toilet switch 37, the lifting unit 100 is lowered due to its own weight, so that the opening and closing member 140 closes the dirt outlet 31 The shielding member 130 is urged toward the lower discharge portion 300 by the first packing 120e and the second lifting hole 130a of the shielding member 130 is pressed by the first packing 120e, 331 are closed and the inflow hole 311 of the discharge part 300 is closed due to the close contact of the second packing 130a.

When the user inserts the wastewater into the toilet bowl 30 in this state, the washing water filled in the separation part 140a between the discharge passage 35 and the opening and closing member 140 is discharged through the waste water discharge hole 140b, It is possible to discharge the wastewater without having to perform the water descending operation even if the large amount of wastewater exceeding the capacity of the main body is discarded and the toilet body 30 can be cleaned by one water drop after discharging the wastepaper, .

5B, when the user starts to lower the after-use operation switch 37, the operation lever 110 is rotated as the water dropping wire 20 is pulled, The lifting rod 120 is raised by pushing up the lifting rod 123.

As the lifting rod 120 is lifted up, the opening and closing member 140 is raised together with the dirt outlet 31 being opened, so that the dirt of the toilet bowl 30 is discharged together with the washing water of the toilet bowl 30,

The first packing 120e is lifted and the second lift hole 331 of the shielding member 130 is opened so that the washing water of the storage portion S flowing into the case 400 is discharged to the first lift And is discharged to the drain port 32 via the hole 223 and the second lift hole 331 of the shielding member 130 via the inner space of the inner cylinder 340.

5C, when the user continues to lower the operation switch 37, the step 121 raises the shielding member 130 as the lifting rod 120 rises above the height in Fig. 5B, The second lift hole 331 of the shielding member 130 is closed by the close contact between the shielding member 130 and the first packing 120e which is raised at the same time the inflow hole 311 of the discharge unit 300 is opened.

The discharge of the washing water to the drain hole 32 is stopped and the washing water in the storage portion S is discharged through the inlet hole 311 and discharged to the rim side drain hole 312 through the inlet hole 310a formed on the outer peripheral surface of the outer tube 310 And cleans the toilet bowl 30 through the rim-side pipe 34.

5D, when the user fully lowers the operation switch 37, the lifting rod 120 continues to rise and the support lever 210 rotates due to the inclined stopper 124, The support lever 210 descends the upper buoy 240 connected with the buoy support 230 and the buoy support 230,

The stopper 124 of the lifting rod 120 is positioned higher than the support lever 210 as the lifting rod 120 is lifted.

At this time, the buoy table support 230 rises as the upper buoy 240 receives the buoyancy force, the support lever 210 connected to the buoy table support 230 is rotated upward,

The upwardly-supported support lever 210 supports the stopper 124 of the lifting rod 120 to stop the lowering of the lifting rod 120 so that the discharge of the washing water is continuously maintained.

At this time, the first packing 120e is brought into close contact with the first lift hole 223 of the control body 220 to close the first lift hole 223.

As shown in FIG. 5E, when the user places the operation switch 37, the operation lever 110 is rotated downward as the force applied to the water dropping wire 20 is removed.

At this time, since the washing water has been discharged a certain amount, the upper buoy 240 is lowered as the water level is lowered, and as the buoy table supporting table 230 is lowered, the supporting lever 210 is rotated again to release the stopper 124.

The lifting rod 120 which can not be lifted by the support lever 210 and the operation lever 110 starts to descend due to its own weight so that the opening and closing member 140 connected to the lower end of the lifting rod 120 is lowered do.

At this time, the shielding member 130 is maintained in a state of being continuously lifted separately from the descent of the lifting rod 120 by buoyancy of washing water discharged to the rim side pipe 34 through the inflow hole 311, So that the rinse water is sufficiently discharged to the rim side pipe 34.

5F, when the lifting rod 120 descends and the washing water is sufficiently discharged, the first packing 120e that is lowered presses the shielding member 130 downward so that the shielding member 130 descends Whereby the inflow hole 311 of the discharge part 300 is closed so that the washing water is no longer discharged from the water tank 33 of the toilet 30.

At this time, the opening and closing member 140 also descends to close the dirt inlet.

Accordingly, when the wash water is replenished to the storage unit S, the upper buoy 240 is lifted by receiving buoyancy, and the buoy support 230 connected to the upper buoy 240 also ascends.

At this time, the support lever 210 connected to the buoy support base 230 rotates upward to restore the previous state. Then, when the user turns down the operation switch 37 to clean the bowl, the present invention can perform efficient washing by repeating the operation as shown in Figs. 5A to 5F.
