Description

CYLINDER PRESSURE CONTROL APPARATUS FOR AUTOMATIC FLUSHING BIDET

Technical Field

[1] The present invention relates to an automatic flushing bidet and, more particularly, to a cylinder pressure control apparatus for automatic flushing bidets, in which the outlet of a water tank is opened by causing a syphon cover, which is connected to the actuation rod, to be simultaneously rotated upwards when an actuation rod is raised in the direction of the upper end of a cylinder by the hydraulic pressure of water supplied to a faucet, thus discharging water in the water tank to a toilet bowl so as to remove feces, and in which the pressure in the cylinder is removed by discharging the water, which has been used to raise the actuation rod, through a drain rib, which is simultaneously opened when a pressure removal part is raised along with the actuation rod in the direction of the upper end of the cylinder, and thus the outlet of the water tank is closed by causing the syphon cover to be simultaneously rotated downward when the actuation rod is lowered in the direction of the lower end of the cylinder by the pressure created by an elastic member.

[2]

Background Art

[3] Generally, after excretion, feces that are located in a toilet bowl main body are removed in such a way that, when a syphon cover is rotated upwards around the axis of an overflow tube by a manual lever, which is pressed by a user, and, thus, the outlet of an water tank is opened and, at the same time, when water stored in the water tank is supplied to the toilet bowl main body via the opened outlet, the feces that are located in the toilet bowl main body are discharged to a treatment system.

[4] However, there is a problem in that non-handicapped persons, whose activities are not limited, can remove feces by causing the water stored in the water tank to be supplied to the toilet bowl main body by smoothly pressing the manual lever, but small children, the elderly, or physically handicapped persons, whose activities are limited, cannot press the manual lever in order to remove feces.

[5] In order to solve this problem, a tank apparatus for toilet bowls was recently disclosed in Japanese Unexamined Pat. No, 2003-313918.

[6] In the previously disclosed patent, water, which is supplied to a tube via a faucet, which is simultaneously opened when a controller is covered by the hand of a user in the state in which a predetermined amount of water is stored in a water tank, flows into an internal casing part, and both the interior of a cylinder and the lower portion of a

blocking unit are pressed by the hydraulic pressure of the water flowing into the internal casing part, by which the cylinder is raised.

[7] When the cylinder is raised, a hook, which is fastened to the upper end of the cylinder, is raised, so that a discharge valve is rotated upwards and an outlet is opened and, at the same time, the water stored in the water tank is discharged via the opened outlet. Accordingly, feces can be removed.

[8] Furthermore, when a predetermined period of time has elapsed after the faucet is opened, the faucet is closed under the control of the controller, so that the supply of the water that enters into the internal casing part is interrupted and, at the same time, the water in the internal casing part is discharged into the water tank through the holes in an external casing part, therefore the internal casing part and the cylinder are lowered by their weight. In this case, when the hook, which is fastened to the upper end of the cylinder, is lowered, the discharge valve is rotated downwards, and thus the outlet is closed. Thereafter, a predetermined amount of water, which is supplied to a water supplying faucet, is stored in the water tank, and thus the apparatus enters a state of readiness for subsequent operation.

[9] In the previously disclosed patent, which is operated as described above, the structure in which feces are removed when the controller is covered by part of the body of the user is used in order to solve the conventional problem. However, the previously disclosed patent is problematic in that the controller must be covered by the hand, but small children, the elderly, or physically handicapped persons, whose activities are limited, may not be able to take such an action after excretion, and in that the cylinder cannot be uninterruptedly raised when water that enters into the cylinder via casing members is discharged to the water tank through the holes via a contact part without a slider being raised.

[10] Furthermore, in the previously disclosed patent, the structure in which the water in the cylinder is discharged through the holes between the internal casing part and the external casing part is used. However, in this structure, the cylinder and the internal casing part cannot be lowered by their weights in the state in which the pressure in the cylinder is maintained and, in addition, the descending operation of the cylinder cannot be accurately performed. Even when the cylinder is lowered, the descending period (for example, several tens of seconds) taken when the cylinder is lowered becomes greater than the complete discharge period taken until the water stored in the water tank is completely discharged. As a result, the waste of water is increased because the water is continuously discharged until the outlet of the water tank is closed, and thus the reliability of the product is lowered.

[49] The pressing member 343 is configured such that a body 343a, the interior of which is perforated so as to be coupled to the outer circumferential surface of the pressure removal part 342, is formed, engaging protrusions 343b, which protrude from a portion of the body 343a to be opposite each other so as to be fastened to the engaging depressions 322e in the actuation rod 322, are formed, and a pressing protrusion 343c, which protrudes from the upper surface of the body 343a so as to be in close contact with a surface in the space 322b of the actuation rod 322, is formed.

[50] Next, the operation of the present invention, which is constructed as described above, is described below.

[51] First, the weight or body of a user, who sits down on a seat S, is detected by a seating detection sensor 110, and whether the user is excreting is determined. If the user is continuously detected by the seating detection sensor 110 over a predetermined period (for example, 6 seconds), it is determined that the user is excreting.

[52] Furthermore, if, after the user's excretion, no user is detected by the seating detection sensor 110 because the user has moved, whether the user defecated or urinated is detected by the seating detection sensor 110 based on the user detection period. If it is determined that the user urinated, under the control of the control unit 100, the valve 200 is opened so as to remove the urine and communication with an actuation unit 300 is made, and thus some of the water supplied from the faucet to the water tank 22 of the bidet 20 is supplied to the actuation unit 300.

[53] As shown in FIGS. 5a to 5e, the water that flows into the actuation unit 300 flows into the body 321a through the inflow hole 321b of the cylinder 321 of the ascending and descending actuation unit 320 via the hose 310 that is fastened to the fastening depression 351 of the clamp 350, and thus the lower surface of the hydraulic pressure maintaining member 322b, which is coupled to the engaging depression 322d of the actuation rod 322 and is mounted to the mounting depressions 321c of the cylinder 321, is pressed. In this case, the lower end of the hydraulic pressure maintaining member 322b is brought into close contact with the inner circumferential surface of the body 321a of the cylinder 321 while being expanded, so that the water can be prevented from leaking out between the hydraulic pressure maintaining member 322b and the body 321a of the cylinder 321. The hydraulic pressure maintaining member 322b of the actuation rod 322 is pressed by the hydraulic pressure of the water that flows into the body 321a of the cylinder 321, that is, the pressure, so that the actuation rod 322 is raised in the direction of the upper portion of the cylinder 321 along the inner surface of the body 321a while compressing the elastic member 323, and thus the

rotation support member 332, which is fastened to the actuation rod 322 using the fastening bolt 334, is raised.

[54] In this case, because the pulling string 14 is fastened to the support member 331' of the pulling string fastening part 331, which is fastened to the fastening support part 324, which is coupled to the upper end of the body 321a of the cylinder 321, the roller gear 333, which is rotatably mounted to the rotation depressions 332' of the rotation support member 332, which is raised along the actuation rod 322, is moved upwards while rotating. In this case, the distance that the pulling string 14 moves is ensured to be approximately two times greater than the distance that the actuation rod 322 moves up.

[55] In this case, the height to which the actuation rod 322 ascends is adjusted such that the shape and size of the water tank 10 and the rotational angle of the syphon cover 13 can be adjusted. In greater detail, when the height adjustment washer 344 of the pressure removal unit 340 is rotated in the direction in which the pressure removal part 342 is coupled to the moving distance adjustment bolt 341, the fastening protrusion 344' of the height adjustment washer 344 causes the body 342a of the pressure removal part 342, which is coupled to the fastening depression 342f, to be rotated, and thus the coupling hole 342b is coupled to the moving distance adjustment bolt 341. In this case, when the moving distance adjustment bolt 341 is located at the upper position in the space 322b of the actuation rod 322 and when the pressure removal part 342 is coupled to the upper end of the moving distance adjustment bolt 341, the moving distance adjustment bolt 341 is located at the lower position in the space 322b of the actuation rod 322, so that the height to which the actuation rod 322 ascends can be adjusted according to the height of the pressure removal part 342, which is coupled to the moving distance adjustment bolt 341, as shown in FIG. 6.

[56] When the pulling string 14 is raised, the syphon cover 13, to which the lower portion of the pulling string 14 is fastened, causes the outlet 11 of the water tank 10 to be opened while being rotated upwards from the overflow tube 12, and thus the water stored in the water tank 10 is discharged to the opened outlet 11. Accordingly, the feces can be removed.

[57] In this case, it is preferred that the syphon cover 13 be implemented using a gravity- type syphon cover.

[58] Furthermore, even in the state in which the water in the water tank 10 is discharged to the outlet 11, when the actuation rod 322 is continuously raised while compressing the elastic member 323 and is located at the lower end of the body 321a of the cylinder 321, the pressing protrusion 343c of the pressing member 343, which is coupled to the space 322b of the actuation rod 322, presses the lower surface of the head part of the moving distance adjustment bolt 341, and thus the moving distance adjustment bolt

341 is raised along the actuation rod 322.

[59] In this case, the pressure removal part 342, to which the moving distance adjustment bolt 341 is coupled, is also raised and, thus, the opening and closing packing 342e, which is fastened to the coupling depression 342d of the pressure removal part 342, is raised. When the opening and closing packing 342e is raised, the drain rib 32 Id of the cylinder 321 is opened. In this case, the ascent of the pressure removal part 342 is stopped when the height adjustment washer 344, which is fastened to the pressure removal part 342 using the fastening support bolt 345, comes into contact with the discharged amount adjustment member 346, which is coupled to the drain rib 321d.

[60] In this case, as shown in FIG. 7, the height to which the pressure removal part 342 ascends can be controlled by adjusting the height that is reached when the discharged amount adjustment member 346 is coupled to the drain rib 32 Id and, in addition, the period that is required to discharge the water stored in the water tank 10 can be adjusted according to the type of the toilet bowl by adjusting the amount of water that is discharged through the drain rib 32 Id while varying the interval between the pressure removal part 342 and the drain rib 321d.

[61] When the water that has been used to raise the actuation rod 322 is discharged through the drain rib 321d via the discharged space 342e' of the opening and closing packing 342e in the state in which the drain rib 32 Id is opened through the above- described process, the internal pressure of the cylinder 321 is removed.

[62] Meanwhile, under the assumption that the drainage period of the water that is stored in the water tank 10 and is required when urination is conducted is 4 seconds, after a water drainage period of 3 seconds has elapsed, the valve 200 is closed under the control of the control unit 100, so that the water that flows into the actuation unit 300 is interrupted and, at the same time, the actuation rod 322 is moved to the lower portion of the body 321 of a cylinder 321 by the restoring force of the elastic member 323, which is compressed when the actuation rod 322 is raised.

[63] In this case, the lower portion of the descending actuation rod 322 presses the pressing member 343 of the pressure removal unit 340 while the water that is located in the body 321a of the cylinder 321 is forcibly discharged through the drain rib 32 Id by the actuation rod 322, which is lowered by the restoring force of the elastic member 323, so that the descending actuation rod 322 and the pressing member 343 are simultaneously lowered, and thus the water that is located in the body 321a of the cylinder 321 is completely discharged through the drain rib 32 Id. In this case, the lower surface of the pressing member 343 causes the support part 342c of the pressure removal part

342 to be lowered by pressing it, and thus the drain rib 321d is closed by the opening and closing packing 342e.

[64] Furthermore, when the rotation support member 332, which is fastened to the

actuation rod 322, which is lowered to close the drain rib 32 Id, is lowered, the force that enables the pulling string 14, which is engaged with the roller gear 333, which is rotatably mounted to the rotation depressions 332' of the rotation support member 332 to support the syphon cover 13, is removed. In this case, the syphon cover 13, from which the supporting force of the pulling string 14 is removed, is rotated downwards from the overflow tube, and thus the outlet 11 of the water tank 10 is closed. Thereafter, an amount of water that corresponds to the amount of the discharged water is supplied from the faucet and is stored in the water tank 10, and thus the apparatus enters a state of readiness for subsequent operation.

[65] Furthermore, under the assumption that the drainage period of the water that is required when defecation is conducted is 8 seconds, if the opened valve 200 is closed under the control of the control unit 100 after a water drainage period of about 6 seconds has elapsed, the feces can be removed through a process that is the same as the above-described process. When the defecation and the urination are conducted, all operations are the same except that there is a difference only in the opening period of the valve 200. Accordingly, feces can be removed by discharging a predetermined amount of flushing water, which is set for defecation or urination, and thus the waste of water can be reduced.

[66] Meanwhile, as shown in FIG. 8, another embodiment of the present invention may further include a weight M, which is mounted to a buoyancy-type syphon cover 13' so as to enable a change to the gravity-type syphon cover 13. The buoyancy-type syphon cover 13,' to which the weight M is mounted, may be operated through the same process as the gravity-type syphon cover 13.
