Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a vertical drainage trap, and particularly provides a drainage trap having a spiral rectifying plate on the upper part of its odor-proof lid.

(Prior art) Conventionally, among the drain traps installed on waterproof pans for washing machines and waterproof pans for bathrooms, in the case of vertical drain traps that drain water in the vertical direction, the drain water entering from the inlet is drained from the upper surface of the cover inside the trap to the main body. It collided with the inner circumferential wall at right angles and was likely to cause turbulent flow while reaching the water sealing section.

(Problems to be solved by the invention) The above-mentioned conventional vertical trap has the disadvantage that turbulent flow occurs within the trap body, making it difficult for the wastewater to flow down smoothly, resulting in poor drainage efficiency and the tendency for dirt to accumulate. Ta.

The present invention proposes a vertical drainage trap that eliminates the above-mentioned conventional drawbacks.

(Means for Solving the Problems) The present invention includes a trap body which is open at the upper end and has an inwardly protruding part and an outwardly protruding part formed by penetrating the drain pipe at the bottom, and a trap body having an inwardly protruding part and an outwardly protruding part formed in the bottom thereof. This drainage trap has a running water space formed around the outer periphery of the inward protrusion and a cover attached thereto, and a spiral current plate is provided on the upper part of the cover.

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 shows an embodiment of the present invention in a longitudinal cross-sectional view,
2 to 4 are plan views showing examples of the spiral current plate attached to the cover, and FIGS. 5 and 6 are longitudinal sectional views showing other embodiments of the present invention.

The trap of this invention has a drain pipe 2 in a trap body 1.
The outer periphery of the inward protrusion 2a is covered with a cover 3 with a predetermined water flow space in between, and this is fixed by appropriate means, and the perforated plate receiving frame 6 is attached to the upper opening of the trap body 1.
A perforated plate 7 is attached through the perforated plate 7, and below the perforated plate 7,
That is, a spiral current plate 4 is attached to the top of the cover 3.

The attached state of the spiral current plate 4 is such that it is integrally formed on the upper surface of the cover 3 and is attached to the perforated plate holder frame 6 by a flange 5 formed at the upper edge of the spiral current plate 4. (Fig. 1), a spiral current plate 4 is separated from the cover 3, and is attached to a perforated plate receiving frame 6 by a flange 5 at its upper peripheral edge (Fig. 5), a spiral current plate 4 is integrally formed on the upper surface of the cover 3 but is not engaged with the perforated plate receiving frame 6 (6th
Figure) etc. That is, in the present invention, as described above, in the vertical drainage trap, the spiral current plate 4 is connected to the cover 3.
It is attached to the upper part of the body by appropriate means.

An example of the shape of the spiral current plate 4 attached to the cover 3 in a plan view is a spiral radial shape as shown in FIGS. 2 to 4 (FIGS. 2 and 3). or a simple spiral (fourth
(Fig.), various spiral shapes and number of rectifying plates are applied.

(Effects of the invention) Since the present invention has the above configuration, it has the following effects:
be effective. In other words, the wastewater flowing in from the perforated plate is
Between the inner wall of the trap body and the cover by the spiral rectifying plate,
Since the flow spirals in a fixed direction between the inner surface of the cover and the inwardly protruding part of the drain tube, it flows out smoothly from the drain tube without creating turbulence, and the swirling flow increases the flow speed, so there is no possibility of dirt clogging. It has excellent drainage efficiency.
