Abstract

PURPOSE:To increase the quantity of drain discharge and enhance drainage performance by installing a drain discharge cylinder in the radial outward direction of a drain outer cylinder, and in the direction deviated leftward along the counterclockwise flow of whirlpools produced in a drain trap. CONSTITUTION:A sealing cylinder 21 is enveloped with a drain outer cylinder 22 while a drain cylinder 24 is inserted into the sealing cylinder 21, thereby constituting a drain trap. In this drain trap, a drain discharge cylinder 23 is installed in the radial outward direction of the drain outer cylinder 22, and deviated leftward along the direction of a counterclockwise flow of whirlpools produced in the drain trap. Furthermore, it is more preferable that a plurality of lines 28 be installed in the drain cylinder 24, which extend radially, and in the shape of whirlpools. Furthermore, it is more preferable that a plurality of long holes 37a, which extend radially, and in the shape of whirlpools, is formed on a drain pan 37 which covers the upper end opening of the drain cylinder 24. This construction makes it possible to turn the flow of drain in the drain cylinder 24 to a turbulent flow directed at the drain discharge cylinder 23 and smooth the flow in a drain chamber 3000 and hence increases the quantity of drain discharge.

As shown in FIG. 1, in the drainage trap according to the present example, the drainage discharge cylinder 13 is biased radially outward with respect to the drainage outer cylinder 12 and in a direction along a counterclockwise spiral flow generated in the drainage trap. It is arranged on the left with care. Water bottle 11
The drainage outer cylinder 12 and the drainage cylinder 14 are arranged concentrically. Except for the above, the structure of this drain trap is the same as the structure of the conventional drain trap shown in FIGS. The drain trap is mounted in the drain opening O formed at the corner of the floor F of the bathroom in the same manner as the drain trap of the conventional structure shown in FIGS. As shown in FIG. 2, the floor F of the bathroom
The drainage flow paths F2 and F3 are formed radially outward of the drainage opening O and are eccentrically connected to the drainage opening O in the direction forming a counterclockwise swirl flow in the drainage trap.

In this drainage trap, the drainage flowing into the drainage pipe 14 from the drainage flow paths F2 and F3 which are eccentrically connected to the drainage opening O formed in the floor F of the bathroom is left in the drainage pipe 14. It creates a spiral flow around it. Drainage pipe 13
Is disposed eccentrically with respect to the drainage outer casing 12 in the radial direction and in the direction along the counterclockwise swirl flow generated in the drainage trap. As compared with a drain trap that extends radially from 102, the flow of drainage in the drainage chamber 300 becomes smoother and the drainage flow rate increases. Therefore, in this drain trap, while maintaining the diameter of the drain cylinder equal to the conventional drain trap,
The drainage performance can be improved as compared with the conventional drainage trap.

A second embodiment of the present invention will be described with reference to FIG. As shown in FIG. 3, in the drainage trap according to the present example, the drainage discharge cylinder 23 is biased radially outward with respect to the drainage outer cylinder 22 and in the direction along the counterclockwise spiral flow generated in the drainage trap. It is arranged in mind. Drainage pipe 23
The connecting portion 23a with the side wall of the drain outer casing 22 of the
It is formed in a funnel shape that is flat toward the top and bottom and expands toward 2. The water sealing cylinder 21 has a drainage discharge cylinder 2 with respect to the drainage outer cylinder 22.
It is arranged so as to be eccentric in the direction away from 3. The drainage pipe 24 is eccentrically arranged with respect to the water sealing pipe 21 in a direction approaching the drainage discharge pipe 23. Fins 28 extending radially and in a counterclockwise spiral are arranged in the drainage pipe 24. Except for the above, the structure of this drain trap is shown in FIGS.
This is the same as the structure of the conventional drain trap.

In this drain trap, the drainage flowing into the drain tube 24 flows along the fins 28 extending radially and spirally in the counterclockwise direction to form a counterclockwise spiral flow in the drain tube 24. . The drainage discharge cylinder 23 is arranged eccentrically with respect to the drainage outer cylinder 22 in the radial direction and in the direction along the counterclockwise swirl flow generated in the drainage trap. The flow becomes smooth and the drainage flow rate increases. Drainage outer cylinder 2 of drainage discharge cylinder 23
Since the connection portion 23a with the side wall of 2 is formed in a funnel shape that expands toward the drainage outer cylinder 22, the flow of drainage from the drainage chamber 300 to the drainage discharge cylinder 23 becomes smooth and the drainage flow rate increases. . In addition, the drainage discharge cylinder 23 is less likely to be clogged with dust, and the drainage discharge cylinder 23 and the drainage pipe D are easily cleaned. Since the water sealing cylinder 21 is disposed eccentrically with respect to the drainage outer cylinder 22 in the direction away from the drainage discharge cylinder 23, the width of the drainage chamber 300 near the drainage discharge cylinder 23 increases,
The drainage flow from the drainage chamber 300 to the drainage discharge cylinder 23 becomes smooth, and the drainage flow rate increases. In addition, drainage pipe 2
Since the gap between the water sealing cylinder 21 and the drainage outer cylinder 22 in the vicinity of 3 becomes wide, the drainage cylinder 24 is removed, and a cleaning tool is inserted from the gap between the water sealing cylinder 21 and the drainage outer cylinder 22 to drain the water. When cleaning 23 and the drain pipe D, it becomes easy to insert the cleaning tool into the gap between the water sealing cylinder 21 and the drain outer cylinder 22. This facilitates cleaning of the drainage discharge cylinder 23 and the drainage pipe D.

Since the drain pipe 24 is eccentrically arranged with respect to the sealing pipe 21 in the direction approaching the drain discharge pipe 23,
The drainage opening formed on the bathroom floor or the like approaches the drainage discharge cylinder 23. As a result, when cleaning the drainage discharge pipe 23 and the drainage pipe D, it becomes easy to make the cleaning tool reach the drainage discharge pipe 23 and the drainage pipe D. As a result, the drainage discharge tube 2
3 and the drain pipe D can be easily cleaned. Also, the drain 2
Since 4 is arranged eccentrically with respect to the water sealing cylinder 21,
The gap between the drain tube 24 and the water sealing tube 21 is expanded, the resistance of the flow path of the water sealing chamber 200 is reduced, and the drainage flow rate is increased.

A third embodiment of the present invention will be described with reference to FIG. As shown in FIG. 4, in the drainage trap according to the present example, instead of the fins arranged in the drainage pipe, a drainage pan 37 covering the upper end opening of the drainage pipe is provided with radial and counterclockwise spirals. A plurality of elongated holes 37a extending in the direction are formed. Except for the above, the structure of the drain trap according to this example is the same as that of the drain trap of the second embodiment. In this drainage trap, drainage flows into the drainage pipe through a plurality of slots 37a formed in the drainage tray 37 and extending in a radial and counterclockwise spiral shape. A swirl flow is formed. The drainage discharge tube is
Since it is eccentrically arranged radially outward and in the direction along the counterclockwise swirl flow generated in the drain trap, the flow of drainage in the drainage chamber becomes smooth and the drainage flow rate increases. Although the embodiments of the present invention have been described above, the present invention is not limited to the above embodiments. For example, the connection portion 23a of the drainage discharge cylinder to the side wall of the drainage cylinder may be formed in a normal funnel shape.
