Flow control structure for toilet one body bidet of valve controlling water suply}

The present invention relates to a flow path control structure of a water supply control device of an integrated ceramic bidet, and more particularly, it is manufactured as a single product while forming the end of the diaphragm to be bent, thereby minimizing the thickness, so that manufacturing cost reduction and durability improvement can be expected. , The diaphragm is combined with the holder to increase the holding force, thereby enabling stable operation by effectively responding to high closing pressure, and the water supply of the ceramic-integrated bidet to selectively filter the water supplied to the orifice by installing a filter inside the holder. It relates to a flow path control structure of a control device.

In general, a bidet is a device that cleans the anus or local area with washing water sprayed through a nozzle so that the toilet of the toilet can be treated cleanly and hygienically.It is usually installed on a toilet, but this is a problem that the overall size is large and the appearance is not beautiful. Accordingly, in recent years, a ceramic-integrated bidet in which a bidet and a toilet are integrally formed has been spreading.

The toilet of the toilet located inside the toilet bowl is supplied to the bowl through the rim side of the pottery and through the jet channel by the operation of the water supply control device, and is discharged to the drain pipe along with the toilet to wash the toilet.

In the water supply control device, when electricity is applied to the solenoid valve, the plunger operates by an electromagnetic force so that the diaphragm opens and closes the water supply hole, and the water filtered by foreign substances through the filter membrane provided in the inlet is discharged to the jet channel or the rim side. do.

However, in the water supply control device as described above, since a filter membrane is provided on the entire intake part, the flow rate of water flowing from the water tank is rapidly reduced by the filter membrane, and in a situation where a large flow rate must be discharged instantaneously, such as a toilet cleaning valve The problem of insufficient flow occurs.

In addition, since a large amount of water flows into the inlet, fine foreign matters are continuously filtered through the filter, and these foreign matters adhere to the filter net as time elapses, and the situation where large foreign matters continue to take is repeated and eventually the entire inlet is blocked. There was a problem that occurred.

The diaphragm is uneconomical due to the increase in the cost and weight of the diaphragm by insert-molding the reinforcing iron core to eliminate deformation due to high pressure when the guide hole is closed. If the thickness of the diaphragm is excessive, a problem occurs in the crystallinity of the diaphragm, and reliability problems such as deformation and swelling of the diaphragm occur.

In addition, since the reinforcing iron core and the rubber are materials of different properties, there is a structural problem in that the rubber and the reinforcing iron core are separated from each other when repeated long-term movements and impacts in water are separated.
