Description

Flush toilet seat {TOILET BOWL}

The present invention provides a minimum amount of water directly from the water pipe into the catchment of the toilet body, and at the same time, it is possible to sequentially remove the excrement at a time, thereby greatly reducing the water consumption, suppressing the generation of noise and blocking the drain passage itself. By flushing the toilet to be able to block even the bad smell to the source.

A conventional flush toilet, which is installed in a restroom of a general home or a common building, includes a toilet body having a seat plate and includes a water tank for supplying a predetermined amount of water into the main body, thereby draining the waste after the toilet and draining water. It is configured to be discharged to the sewer through pipes.

In addition, most of the flush toilets have S-shaped traps with drainage passages between the toilet body and the sewage pipes to block backflow odors. There is an unreasonable problem of increasing unnecessary water consumption because it can only provide a considerable amount of water.

As a technology for improving such a problem, Korean Laid-Open Patent Publication No. 2001-0112040 discloses an amount of water required for cleaning the toilet by installing a trap opening and closing plug and an odor prevention barrier at a lower end of a trap connected directly to the bottom of the toilet body. In addition, to reduce the odor is described as an example to prevent the rise, and also published in the Patent Publication No. 2006- 0060437 and at the same time to install a water level control device to control the water level in the water tank at the user's own By replenishing the residual water through the technology disclosed that the odor countercurrent blocking function can be surely exhibited.

However, in the above structure, although the amount of water used to remove the feces can be reduced to some extent, both technologies have a complicated structure due to the complicated construction of separate parts installed between the toilet body and the drain passage, and it is not easy to operate. There is a high risk of occurrence and maintenance is not easy.

On the other hand, as a technology for effectively removing the odor at the time of toilet, for example, Korean Patent Laid-Open No. 2006-0088521 discloses a suction passage provided with a plurality of suction ports and blowers formed on the bottom of the seat plate to suck the odor due to excrement An example of removing the odor is described, and Patent Publication No. 2007-0103323 discloses that the odor generated inside the toilet is discharged to the outside through a sewage pipe and a vent pipe at the bottom by a discharge means provided in the toilet. As described above, it describes a technique for more efficiently discharging the odor inside the toilet without the need for a separate plumbing facility.

However, the odor removing device of the prior art as described above can be forced out by the operation of the blower, but the effect is reduced because the odor flows back into the toilet when the operation of the blower is stopped, and various sensors Since it consists of a circuit configuration such as a controller provided, there is a hassle that the noise occurs and the failure rate is high, and the maintenance must be performed from time to time.

In addition, since the hose or pipes connected to the wall, floor, ceiling, etc. in the bathroom must be connected to the toilet itself, it is not aesthetically pleasing, and it is difficult to perform a separate construction work and to bear various installation costs. It was inherent.

Applicant has already been disclosed in Korean Patent Nos. 0941293 and 0941294 with respect to such a flush toilet, and can directly supply a minimum amount of water from the water tank while simultaneously injecting air or by means of a cam. A technique has been proposed for operating a piston in a cylinder to remove excreta in the catchment.

However, in these cases, since the water supplied from the water pipe must be provided into the sump through the linkage shaft designed to operate in the casing by the motor drive, it causes a failure due to foreign matters, and also generates air or a cam. The structure of the interlocking parts for operating the system is complicated and high costs are required.

Moreover, in these flush toilets, there is a problem that noise is largely generated and durability is degraded when air pressure is generated or when the piston is operated by driving each motor.

Therefore, the research on the structural problems of the toilet seat proposed by the present applicant has been studied to develop a more excellent flush toilet seat, the object of the present invention is to provide a minimum of water directly from the water pipe, as before, It does not require the water supply unit by interlocking, and it is possible to move the piston in the housing while the guide shaft is fixed even when removing the excrement, simplifying the overall linkage structure, greatly reducing the manufacturing cost and noise by the buffer means And it is to provide a flush toilet seat to suppress the occurrence of a failure.

The present invention for achieving the above object, in a conventional flush toilet comprising a toilet main body having a water collecting port and a seat plate and a cover mounted to be rotatable on the toilet main body, it is provided on one side of the toilet main body It consists of a water supply unit for directly supplying water from the water pipe to the catch port side of the toilet body and a suction unit operative to open or close the drain passage through which excrement flows from the catch port, the water supply unit is electrically Water is supplied directly from the water pipe to the discharge hole installed in the water collecting port by a check valve and a timer operated by the pump. The suction unit elastically moves the piston forward and backward according to the cam rotated by the motor and the operation of the cam. It is configured to discharge the waste in the catchment It is characterized by.

In addition, a hydraulic pressure control valve is added to one side of the water valve constituting the water supply unit.

In addition, the suction unit includes a cam rotated in one direction by a motor, a piston reciprocating in the housing by the cam, a guide shaft disposed and fixedly installed in the piston, and a pusher mounted on an outer circumferential surface of the piston. It is characterized by consisting of a spring provided between the piece and the position regulating piece to provide elasticity.

In addition, a clutch bearing is attached to one end of the shaft on which the cam is mounted, so that the cam can be forcibly rotated by manually operating the operating lever.

In addition, a buffer oil is interposed at the distal end of the piston.

As described above, according to the flush toilet according to the present invention, since water is consumed since it is configured to apply a predetermined suction force to the drain passage in the catchment while supplying the minimum water directly from the water pipe without requiring a water tank, the excrement can be temporarily removed. Can be greatly suppressed.

In addition, since the present applicant does not need the water supply unit composed of the gear group linkage and the casing and the linkage shaft as in the previous patented products, it is possible to greatly reduce the manufacturing cost due to the reduction of the interlocking parts.

In addition, even when the excrement is removed, it is possible to remove by the operation of the piston having a shock absorbing means in the fixed state of the guide shaft, further excellent durability and can significantly reduce noise generation.

In addition, by allowing the suction passage to be blocked by the suction unit, it is possible to fundamentally block the occurrence of odor or backflow phenomenon.
