DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a floor drain trap.

[0002]

2. Description of the Related Art A conventional floor drain trap is shown in FIGS.
This is the structure shown in FIG. The drain trap body 100 has an outlet tube 102 communicating with an outlet 101 at the bottom center, and the upper opening 10 of the drain trap body 100.
The inflow cylinder 104 has a cover 103 attached to the opening 0a and having a mesh-shaped perforation in the opening, and a bowl-shaped body 105 which is placed upside down on the outflow cylinder 102 of the drain trap body.

As shown in FIG. 4, when the odor S from the drain pipe (not shown) attempts to enter the drain trap, the inner periphery of the bowl 105 and the drain trap body are disposed. The water W that has flowed into the gap L with the outer periphery of the outflow cylinder 102 prevents entry.

[0004]

However, on the other hand, such a structure has a problem that water flowing into the inflow cylinder 104 does not flow smoothly to the outlet 101.

That is, as shown in FIG. 5, the water W that has flowed into the inflow cylinder 104 once strikes the bottom of the drain trap body 100 to be damped, and then rises vertically through a narrow passage. The momentum is further reduced, and again strikes the inner bottom surface of the bowl 105.

As a result, the water that has flowed into the inflow cylinder 104 does not flow smoothly to the outlet 101, and even if the amount of drainage is not so large, the water cannot easily be discharged.

SUMMARY OF THE INVENTION The present invention has been made in view of the above, and has as its object to provide a floor drain trap capable of smoothly flowing water flowing into an inflow cylinder to an outlet.

[0008]

SUMMARY OF THE INVENTION The gist of the present invention is to provide a drain trap body 2 having an outlet tube 4 communicating with an outlet 3 at the center of the bottom, and an upper opening of the drain trap body 2. A drain trap 1 comprising an inflow cylinder 5 having a lid 6 perforated in a mesh shape at the opening, and a diameter larger than that of the outflow cylinder 4 of the drain trap main body 2, and a small amount of water on the lower surface of the outer peripheral portion. And a float 9 having a short annular body 10 extending in a row, which is attached to a guide rod 7 to be described later so as to be able to move up and down. The guide rod 7 rises vertically to the center of the outflow cylinder 4 of the drain trap body. Outflow cylinder 4
The length extending upward is not the length that the upper surface of the float 9 does not block the perforation of the lid 6 when the float 9 rises, and the lower end of the annular body 10 is located above the opening of the outflow cylinder 4. A supporting member 8d is supported by supporting rods 8c, 8c at the center of a cylindrical main body 8b having a portion 8a formed at an upper end thereof for locking the guide rod 7 at an upper end opening of the outflow cylinder 4 of the drain trap main body 2. The float 9 is opened and closed by opening and closing the float 9 by supporting the supporting member 8d of the supporting member 8 of the guide rod and fixing the supporting member 8 of the guide rod to the outflow cylinder 4 of the drain trap main body 2. The floor drain trap is attached to the drain trap main body 2 so as to be able to move up and down freely.

Further, a weight may be attached to the float. As a result, when the float descends due to the drop in water level, it becomes smoother, and when the water level drops, the degree of adhesion between the lower surface of the float and the upper end of the outflow cylinder increases, and the ability to prevent odor from entering the drain pipe further increases. .

[0010]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a sectional view of a main part of the present invention, FIG. 2 is a plan view of a guide rod supporting member, and FIG.

In FIG. 1, reference numeral 1 denotes a floor drain trap, which comprises the following parts. Reference numeral 2 denotes a drain trap body. The drain trap body 2 has a cylindrical shape with a bottom, and an outlet tube 4 communicating with the outlet 3 stands at the center of the bottom.

Reference numeral 5 denotes an inflow cylinder connected to the upper opening of the drain trap body 2. Further, a lid 6 perforated in a mesh shape is attached to the opening of the inflow cylinder 5.

Reference numeral 7 denotes a guide rod vertically supported at the center of the outflow cylinder 4 of the drain trap body. In the present embodiment, a male screw 7a is engraved on the lower end.

Numeral 8 denotes a member for supporting the guide rod 7, which is provided on the outflow cylinder 4 of the drain trap body.
The float is attached to the drain trap body 2 so as to be able to move up and down so as to open and close the opening of the outflow tube 4 by fixing the float to the drain trap body 2. The support member 8 of the guide rod is a part 8 to be hooked on the upper end opening of the outflow cylinder 4 of the drain trap body.
The supporting body 8d is supported by supporting rods 8c, 8c at the center of a cylindrical main body 8b having a at the upper end. Also,
A female screw 8e screwed into the male screw 7a of the guide rod 7 is formed in the center of the support 8d in the vertical direction. Thus, the height of the guide rod 7 is adjusted so that the later-described float elevating stroke can correspond to the height of the inflow cylinder 5. The length of the guide rod 7 is such that the upper surface thereof does not block the perforation of the lid 6 when the float floats up, and the lower end of the annular body is located above the opening of the outflow cylinder 4. Length.

A float 9 is attached to the guide rod 7 so as to be able to move up and down. In this embodiment, the float 9 is made of a resin hollow body, but may be made of a material having a low specific gravity such as styrene foam or balsa material.

The float 9 has a larger diameter than the outflow cylinder 4 of the drain trap body, and an annular body 10 of a required length is continuously provided on the lower surface of the outer peripheral portion. The ring 1
Reference numeral 0 denotes a state in which water does not flow, that is, a short length slightly below the surface of the water when the float 9 is placed on the outflow tube 4 of the drain trap body, thereby preventing odor from entering the drain pipe.

Reference numeral 11 denotes a weight having a required weight attached to the float 9.

Next, the operation of the present embodiment will be described. In a state where no water is drained, the float 9 is placed on the outflow cylinder 4 of the drain trap body as shown in FIG.
At this time, the annular body 10 also goes under the water surface to prevent odor from entering from the drain pipe.

When the drainage starts, as shown in FIG. 3, the float 9 rises along the guide rod 7 as the water level in the inflow cylinder 5 rises.

As a result, there is no covering on the upper part of the outflow cylinder 4 of the drain trap body, so that the water flowing into the inflow cylinder 5 can smoothly flow into the outflow cylinder 4 instead of the complicated flow unlike the conventional drain trap. It flows in. This greatly improves drainage efficiency.

[0021]

According to the present invention, the drainage efficiency can be greatly improved because of the above-described structure and operation. In addition, when a weight is attached to the float, the float becomes smoother when descending due to a drop in the water level, and when the water level drops, the degree of adhesion between the lower surface of the float and the upper end of the outflow cylinder increases, and the drain pipe The ability to stop odors from coming in is further increased.
