The strainer assembly includes a disc-shaped base that has an annular plate portion with a downward inner flange, and a U-sectioned cup portion having a bottom central hole and being supported in the annular plate portion by ribs with an open area left between them; a membrane strainer made of an elastic and flexible material and having a thin annular portion, on which locating rods are provided for engaging with locating holes on the base to thereby fix the membrane strainer below the flange to normally seal the open area; and a gasket ring fitted around the base for the whole strainer assembly to stably seat in the pit of the main body.
Description
- The present invention relates to a floor drain with membrane strainer, and more particularly to a floor drain having a membrane-type strainer assembly mounted in a main body thereof to effectively prevent stink and insects in a drainpipe from entering into a room via the floor drain.
- Taiwanese Patent Publication No. 210687 discloses a stink-isolating floor drain. The floor drain has a seat with drain water holes, a dome-shaped hollow cap upward projected from a perimeter of the seat, and an inverted bowl portion downward extended from a bottom of the seat. When an amount of drain water is accumulated between an outer side and an inner conic draining face of the dome-shaped cap to submerge the inverted bowl portion, stink in a drainpipe below the floor drain is prevented from moving upward into a room via the floor drain. The floor drain disclosed in the above Taiwanese patent fails to drain water smoothly because water could not be drained via a central hole of the dome-shaped cap before it submerges the cap. Dust and debris tends to cumulate between the outer side and the inner conic draining face of the dome-shaped cap to produce stink or even clog the floor drain.
- Taiwanese Patent Publication No. 287567 discloses a valve-type bathroom floor drain having a strainer top and a base to define a funnel-shaped pit between them, and an elastic plastic valve fitted in the funnel-shaped pit. The elastic plastic valve is provided with a plurality of widely spaced valve members corresponding to drain holes on the strainer top and a considerably large central hole, and is not tightly attached to an underside of the drain holes. That is, the floor drain having been fully installed for use is in a completely open state without any shielding means, and therefore completely fails to stop stink in a drainpipe from moving upward into the bathroom via the floor drain, not to mention mosquitoes and insects in the drainpipe.
- It is therefore tried by the inventor to develop a floor drain with membrane strainer to overcome drawbacks existed in the conventional floor drains.
- A primary object of the present invention is to provide a floor drain with membrane strainer that effectively prevents stink and insects in a drainpipe from entering into a room via the floor drain.
- To achieve the above and other objects, the floor drain with membrane strainer according to the present invention mainly includes a main body having a funnel-shaped pit, a flat grate mounted on a top of the main body using a fastening element, and a strainer assembly mounted in the main body below the flat grate. The strainer assembly includes a disc-shaped base that has an annular plate portion with a downward flange provided along a lower inner edge thereof, and a U-sectioned cup portion having a bottom central hole and being integrally supported at a center of the annular plate portion by ribs, such that an open area is formed between the annular plate portion and the cup portion for drain water to flow therethrough; a membrane strainer that is made of an elastic and flexible material and includes a thin annular portion, on which locating rods are provided for engaging with locating holes on the base to thereby fix the membrane strainer below the base to normally seal the open area; and a gasket ring fitted around the base for the whole strainer assembly to stably seat in the funnel-shaped pit of the main body.
- A seal ring and an elastic element are sequentially positioned in the cup portion around the fastening element, and thereby seal a joint of the bottom central hole of the cup portion and the fastening element in an airtight manner.
- The membrane strainer made of elastic and flexible material provides excellent elastic stress to normally elastically seal the open area between the annular plate portion and the cup portion of the base and thereby effectively prevents stink and insects in a drainpipe from entering into a room via the floor drain. And, when the membrane strainer is subjected to a weight of drain water, its outer peripheral area is elastically bent downward to open the open area for drain water to flow therethrough.
