Description

Drain trap with double water sealing structure

The present invention relates to a drain trap, which is installed on the floor of, for example, a bathroom, a toilet, a veranda, a laundry room, etc., to enable drainage of sewage water while preventing blockage caused by foreign substances and backflow of foul odors. More specifically, the present invention relates to a drain trap having a double-sealing structure in which a second sealing structure is provided within a first sealing structure provided within a drain trap body, so that backflow of foul odors can be prevented more effectively, and the first sealing support cover which is installed on a drain trap support cover can prevent the leakage of foul odors within the drain trap body, and a waterproof layer with excellent adhesion can be easily formed since a water-blocking dam is protruded and formed on the outside of the first sealing support cover, and the phenomenon of water flowing in through damaged areas of tiles and mortar layers leaking into a floor concrete layer can be prevented.

In modern homes, bathrooms, toilets, verandas, laundry rooms, etc., drains are installed in the center of the floor or in a corner of the floor to drain sewage.

In addition, a drain trap is installed in the drain to prevent the drain from being blocked by foreign substances such as hair through a filter net, and to prevent bad smells from flowing back through a water sealing structure.

As an example of such a drain trap, Korean Utility Model Publication No. 20-2017-0002282 (June 27, 2017) discloses a floor drain device for a layered pipe, which is installed on reinforced concrete for a bathroom floor and is formed in a body shape with an open upper surface, and a first drainage connection pipe is extended on one side in a state separated from the reinforced concrete for a base floor, an external member accommodated in the floor drain body and formed in a body shape with an open upper surface, an upper frame which is seated on the upper end of the floor drain body and has a first step formed on the lower side of the inner surface and a second step formed on the upper side of the inner surface, an internal member which is formed to penetrate in the vertical direction and extends into the interior of the external member while being seated and supported by the first step of the upper frame and having a lower end separated from the bottom surface of the external member, and a second member of the upper frame. A floor drainage device for a layered pipe is disclosed, which includes a drainage cover that is installed on a second step and has a plurality of drainage holes formed therethrough, and an L-shaped or T-shaped drainage section in which a second drainage connection pipe, into which a first drainage connection pipe of the floor drain body is inserted and connected, is extended in a state spaced from the reinforced concrete for the foundation floor on one side and a third drainage connection pipe is extended on the other side.

In addition, Korean Utility Model Registration No. 20-0327222 (2003.09.19.) discloses an indoor floor drainage device having a main drainage tank installed on a floor slab, a drainage frame having a drainage groove formed in a longitudinal direction exposed on the upper surface of the floor slab and a drainage hole formed in communication with the main drainage tank, and an outer filter frame coupled to the upper surface of the drainage frame to filter foreign substances, wherein a support ledge is formed on the upper edge of the drainage hole and an inner wall forming a discharge passage communicating with the main drainage tank, an outer wall having a flange formed on the upper end supported by the support ledge and forming a receiving space for receiving domestic wastewater together with the inner wall, a sealing tube formed by a bottom surface forming the bottom of the inner and outer walls, a sealing cap having a closed upper surface and an open lower surface and coupled between the inner and outer walls, and a spacing maintenance means for maintaining the sealing cap at a predetermined spacing with respect to the sealing tube are provided. The floor drain device is initiated.

In the case of conventional drain traps as described above, there is a problem in that a single sealing structure is applied to prevent foul odors in the drain pipe from flowing back as some of the drained wastewater is always filled, and therefore foul odors generated in the drain trap body cannot be prevented from flowing in through damaged parts of the waterproof layer.

In addition, there is a problem that the waterproof layer cannot be perfectly sealed to the outer surface of the drain trap having an irregular shape, and especially when micro cracks occur in the mortar layer, the foul odor inside the drain trap body can be discharged to the outside without going through the sealing structure.

FIG. 1 is a cross-sectional view of a drain trap having a double-sealed structure according to one embodiment of the present invention, and FIG. 2 is a cross-sectional view explaining the operation of a drain trap having a double-sealed structure according to one embodiment of the present invention.

A drain trap having a double sealing structure according to one embodiment of the present invention comprises: a drain trap body that is embedded and fixed in a floor concrete layer and has a drain pipe connected to one side; a drain trap support cover that is connected to the upper end of the drain trap body and has a flange that is supported and fixed on the floor concrete layer at the upper end and protrudes radially outward; a first sealing support cover that is secured to the drain trap support cover and has a first mounting ring provided on the inner side and a water barrier dam that is supported at the lower end by the flange and has a waterproofing layer in close contact with it and is formed to protrude upward; a sealing tube whose upper edge is secured and supported by the first mounting ring of the first sealing tube support cover and whose upper outer surface has a drainage hole formed spaced apart; a first vertical sealing tube that is supported at the upper end of the sealing tube and extends into the sealing tube and has an open lower end; a second sealing tube that is supported spaced apart from the first sealing tube support cover; and a second sealing tube that is supported at the inner edge of the second sealing tube support cover and is formed to protrude upwardly. It includes a second vertical water pipe extending into the vertical water pipe and having an open bottom.

From here on, each component and its connection relationship of a drain trap having a double-sealed structure according to one embodiment of the present invention will be described in detail with reference to FIGS. 1 and 2.

A drain trap (1) having a double seal structure according to one embodiment of the present invention includes a drain trap body (10), a drain trap support cover (20), a first seal support cover (30), a seal tube (40), a first vertical seal pipe (50), a second seal support cover (60), and a second vertical seal pipe (70), as shown in FIGS. 1 and 2.

Here, the drain trap body (10) forms a casing of a drain trap (1) having a double-sealed structure according to one embodiment of the present invention, and is embedded and fixed in a floor concrete layer (2) forming the floor of, for example, a bathroom, toilet, veranda, laundry room, etc.

In addition, a drain pipe connection part (11) is formed protrudingly on one side of the drain trap body (10) to which a drain pipe (6) that is buried and fixed in the floor concrete layer (2) is connected. In addition, a connecting projection (12) is formed protrudingly on the upper inner side of the drain trap body (10) to enable a drain trap support cover (20) to be connected to the drain trap body (10) in a height-adjustable manner, which will be described later.

A drain trap support cover (20) is attached to the upper end of the aforementioned drain trap body (10). The drain trap support cover (20) serves to guide the drain trap body (10) to be buried and fixed at a certain depth on the floor concrete layer (2), and is supported and fixed on the floor concrete layer (2) so as to be exposed on the floor concrete layer (2).

To this end, a flange (21) that is supported and fixed on the floor concrete layer (2) is formed to protrude radially outward at the top of the drain trap support cover (20). This flange (21) also serves to form a kind of support base that supports the first seal support cover (30) to be described later.

In addition, a fixing step (22) is formed on the inner upper part of the drain trap support cover (20) for the fixing and joining of the first seal support cover (30) to be described later.

In addition, it is preferable that the drain trap support cover (20) be height-adjustably coupled to the drain trap body (10). To this end, it is preferable that a multi-stage coupling groove (23) is formed on the lower outer surface of the drain trap support cover (20) to be selectively coupled to the coupling projection (12). The multi-stage coupling groove (23) has a structure in which a plurality of ring-shaped grooves are formed spaced apart in the vertical direction.

The first sealing support cover (30) is fixedly connected to the aforementioned drain trap support cover (20). The first sealing support cover (30) supports the drain trap main body (10) so that the sealing tube (40) and the first vertical sealing pipe (50), which will be described later, can be installed to form the first sealing structure.

To this end, a fixing projection (31) that is fixedly connected to the fixing step (22) of the drain trap support cover (20) is formed to protrude downward in the center of the first seal support cover (30), and a first fixing ring (32) for fixing the sealing tube (40) and the first vertical sealing pipe (50) is provided on the inside of the first seal support cover (30).

In addition, a water barrier dam (33) is formed to protrude upward on the outer side of the first sealing support cover (30). The water barrier dam (33) is supported at the lower end by the flange (21) of the drain trap support cover (20) and at the same time, the outer side is adhered to the waterproof layer (3), thereby facilitating the formation of a waterproof layer (3) with excellent adhesion for the drain trap (1) having a double sealing structure according to one embodiment of the present invention, and also preventing water flowing in through damaged areas of the tiles (5) and the mortar layer (4) from leaking into the floor concrete layer (2).

It is preferable that the height of the water barrier dam (33) be formed to be the same as the height of the inner edge of the waterproof layer (3) surrounding the drain trap (1) having a double seal structure according to one embodiment of the present invention.

The upper edge of the sealing tube (40) is supported by the first mounting ring (32) of the first sealing support cover (30) described above. The sealing tube (40) is formed in a body shape with an open upper surface, so that a portion of the wastewater that is always discharged is stored at a certain height, thereby blocking the lower end of the first vertical sealing tube (50) described later by the wastewater, thereby preventing the foul odor from flowing back into, for example, a bathroom, toilet, veranda, laundry room, etc.

At the upper edge of the sealing tube (40), a first fixing flange (41) that is fixedly supported by the first fixing ring (32) of the first sealing support cover (30) is formed by being bent radially outward and protruding, and a number of drainage holes (42) are formed spaced apart and penetrating through the upper outer surface of the sealing tube (40) to provide sewage that has accumulated in the sealing tube (40) to the drain trap body (10) for drainage.

The first vertical sealing pipe (50) is supported on the upper end of the aforementioned sealing tube (40) and extends into the sealing tube (40). The first vertical sealing pipe (50) forms a typical sealing structure together with the aforementioned sealing tube (40). At the upper edge, a second mounting flange (51) that is mounted and supported on the first mounting flange (41) of the sealing tube (40) is bent radially outward and formed to protrude, and the lower end is formed to be open so as to allow downward drainage while being closed by sewage inside the sealing tube (40) to prevent backflow of foul odors. This first vertical sealing pipe (50) has an overall shape similar to a funnel.

The sealing structure formed by the sealing tube (40) and the first vertical sealing pipe (50) is the same as the sealing structure applied to a conventional drain trap, so further detailed description is omitted here to simplify the specification.

The second sealing support cover (60) is supported so as to be spaced upward from the first sealing support cover (30) described above. The second sealing support cover (60) supports the second vertical sealing pipe (70) to be described later so that it extends into the first vertical sealing pipe (50), thereby forming a double sealing structure.

A second mounting ring (61) is formed on the inner edge of the second sealing support cover (60) to support the upper end of the second vertical sealing pipe (70), and a spaced support ring (62) is provided on the lower end of the second sealing support cover (60). The spaced support ring (62) supports the second sealing support cover (60) by spaced upward from the first sealing support cover (30), and the lower end is supported by the flange (21) of the first sealing support cover (30) and the upper end supports the lower end of the second sealing support cover (60).

On the inner edge of the second sealing support cover (60) described above, a second vertical sealing pipe (70) is supported and extends into the first vertical sealing pipe (50). The second vertical sealing pipe (70) forms a double sealing structure within the drain trap body (10) together with the sealing tube (40) and the first vertical sealing pipe (50). At the upper edge, a support protrusion that is secured and supported on the inner edge of the second sealing support cover (60) is formed to protrude downward, and the lower edge is formed to be open so as to allow downward drainage while being closed by waste water within the sealing tube (40) to prevent the backflow of foul odors. This second vertical sealing pipe (70), like the first vertical sealing pipe (50), has an overall shape similar to a funnel.

A pressure fixing ring (80) is attached to the inner surface of the first sealing support cover (30) described above. The pressure fixing ring (80) serves to pressurize and fix the first fixing flange (41) of the sealing tube (40) and the second fixing flange (51) of the first vertical sealing pipe (50) to the first mounting ring (32).

In order to join the pressure fixing ring (80), it is preferable that a joining groove be formed on the inner surface of the first sealing support cover (30) to which the radially outer end of the pressure fixing ring (80) is joined.

In the case of a drain trap (1) having a double sealing structure according to one embodiment of the present invention as described above, since a double sealing structure is provided in which a first vertical sealing pipe (50) is installed in a sealing tube (40) provided in the drain trap body (10) and a second vertical sealing pipe (70) is installed again in the first vertical sealing pipe (50), the backflow of foul odor can be prevented more effectively, and the first sealing support cover (30) which is mounted on the drain trap support cover (20) can prevent foul odor from leaking inside the drain trap body (10), and since a water barrier (33) is protrudedly formed on the outside of the first sealing support cover (30), not only can a waterproof layer with excellent adhesion be easily formed, but also there is an advantage in that the phenomenon of water flowing in through damaged areas of tiles (5) and mortar layers (4) leaking into the floor concrete layer (2) can be prevented.

In other words, when a drain trap (1) having a double sealing structure according to one embodiment of the present invention is installed on the floor of a bathroom, toilet, veranda, laundry room, etc., the odor blocking effect is enhanced by the double sealing structure formed by the sealing tube (40) and the first and second vertical sealing pipes (50, 70), and the waterproof layer (3) can be easily formed tightly by the first sealing support cover (30) in which the water barrier (33) is protruded, while at the same time, the phenomenon of water leakage into the floor concrete layer (2) can be prevented, which has the advantage of being possible.

Although the above has been described by way of example only, it will be apparent to those skilled in the art that the present invention may be embodied in many other forms without departing from the spirit and scope thereof. Accordingly, the above-described embodiments are to be considered as illustrative rather than restrictive, and all implementations falling within the scope of the appended claims and their equivalents are intended to be included within the scope of the present invention.
