Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bathroom drain structure that collects hair in wastewater flowing from a bathroom to a drain.

When you wash your head in the bathroom, loose hair is always present in the drain water. It is not good for the environment if the wastewater is directly discharged into sewers. Therefore, a basket-shaped filter is provided before the waste water flows out to the drain port, and the hair is filtered out and collected (see, for example, Patent Document 1).

JP-A-2004-113781 (Claim 1, filter 30 in FIG. 1)

If wastewater is filtered through a basket-shaped filter as in the conventional drain structure described above, the filter will become clogged with filtered hair, and the wastewater will no longer flow to the drain. In addition, filters are easily clogged by sticky substances produced by mold and bacteria.

Therefore, it is necessary to frequently clean the filter, but hair gets tangled in the opening of the filter, making cleaning the filter troublesome.

SUMMARY OF THE INVENTION In view of the above-mentioned problems, it is an object of the present invention to provide a bathroom drain structure that can easily collect hair in drainage water, reduce the frequency of cleaning, and facilitate cleaning work.

In order to solve the above problems, the bathroom drain structure according to the present invention is a bathroom drain structure that collects hair flowing into a drain provided on the floor of the bathroom. A lid plate is provided in the center of the lid plate to guide the drainage water flowing into the upper surface of the lid plate into the drain port, and a brush-like collection member is provided. The tip of the brush tooth is attached so as to be in contact with the upper surface of the lid plate, and the hair contained in the wastewater is caught by being entangled with the brush tooth before flowing out from the opening into the drain port.

Instead of filtering wastewater with a conventional basket-shaped filter, hair is collected by entangled with the teeth of a brush-shaped collection member to prevent the filter from clogging.

In addition, by forming a labyrinth portion on the upper surface of the lid plate to extend the length of the flow path of the wastewater flowing to the opening, the probability that hair will become entangled with the brush teeth is increased.

Furthermore, when there is a large amount of drainage water, there is a risk that the collection member will float; however, a floating prevention means is provided to prevent the collection member from floating and the tips of the brush teeth being separated from the upper surface of the cover plate. is desirable.

If the collection member is provided with a compression plate that moves to the first push-in position and compresses the hair entangled with the brush teeth, the frequency of cleaning the collection member can be reduced.

Furthermore, the compression plate is formed to be movable to a second push-in position beyond the first push-in position, and the compression plate is moved to the second push-in position with the collection member removed from the lid plate. If hair entangled in the brush teeth can be removed from the brush teeth by the compression plate, cleaning of the collection member becomes easier.

As is clear from the above description, the present invention can collect hair in waste water without using a basket-shaped filter, and therefore can avoid problems such as clogging of the filter.

Referring to FIG. 1, reference numeral 1 indicates the floor surface of a bathroom, and a drain port 2 is provided in a drain pit 11 formed on the floor surface 1 and hidden by a cover plate 12. In order to prevent hair from flowing into the drain port 2 together with the water from the drain port 2, a cover plate 3 shown in FIG. 2 is provided.

Referring to FIGS. 2 and 3, a plurality of protrusions 30 are formed on the outer circumferential surface of the cover plate 3, and contact the opening edge 21 of the drain port 2 to prevent the cover plate 3 from floating up from the drain port 2. are doing.

A pair of handles 31 are provided on the upper surface of the lid plate 3 for removing the lid plate 3 from the drain port 2. Further, an opening 32 is formed in the central portion, and a triple peripheral wall 33 surrounding this opening 32 is formed. These three peripheral walls 33 all have multiple cutouts, and the sandwiched portions of the peripheral walls 33 form a labyrinth 34 through which drainage water flows, flowing from the outer peripheral portion of the lid plate 3 to the upper surface of the lid plate 3. Drainage water is directed through this labyrinth 34 to the central opening 32.

The hair flows in the labyrinth 34 along with the drainage water, and a collection member 4 for collecting the hair flowing together with the drainage water is placed on the top of the lid plate 3.

As shown in FIG. 4(a), three positioning columns 42 are provided on the lower surface of the main body 41 of the collection member 4. The tips of these columns 42 fit into the labyrinth 34 and abut against the peripheral wall 33, thereby positioning the collection member 4 in the horizontal direction. Furthermore, permanent magnets 42a are cast into the tip portions of these columns 42 during injection molding. Since an iron ring 3a, which is a magnetic material, is cast into the lid plate 3, when the collection member 4 is placed on the lid plate 3, the magnetic force of the permanent magnet 42a moves the collection member 4 upward. lifting is prevented. Note that this prevention of floating may be achieved, for example, by removably engaging the tip portion of the support column 33 with the peripheral wall 33, instead of using the permanent magnet 42a.

Further, on the lower surface of the main body 41 of the collection member 4, a plurality of brush teeth 43 whose tip portions enter the labyrinth 34 are provided. Therefore, as described above, the hair in the wastewater flowing within the labyrinth 34 will be collected at the tips of the brush teeth 43. Since the hair is collected in this way, only the waste water flows into the central opening 32.

The collection member 4 is provided with a compression plate 44 . This compression plate 44 has the support column 42 and brush teeth 43 passed through it, and is attached upward by a spring 45 compressed between the push member 46 fixed to the compression plate 44 and the main body 41. Forced.

When hair is collected by the brush teeth 43, it floats toward the main body 41 side. In that case, when the pushing member 46 is pushed down while still placed on the cover plate 3, the compression plate 44 moves downward until it comes into contact with the upper end of the peripheral wall 33, as shown in FIG. This compresses the hair collected on the brush teeth 43. The position in contact with the upper end of this peripheral wall 33 is defined as a first push-in position.

If the compression plate 44 is pushed down to the first push-in position to compress the hair collected on the brush teeth 43, it can be used as is, but if this compression is repeated multiple times, the hair collected on the brush teeth 43 will be compressed. The hair will have to be removed. In that case, the collecting member 4 is removed from the lid plate 3 and the pushing member 46 is pushed in.

Referring to FIG. 5, when the push member 46 is pushed in with the collection member 4 removed from the lid plate 3, the push member 46 is pushed in until it comes into contact with the upper end 41a of the main body 41. This position is defined as the second push-in position. When the pushing member 46 is pushed to this second pushing position, the compression plate 44 moves to the vicinity of the tip of the brush teeth 43, so that all the hair collected on the brush teeth 43 is removed from the brush teeth 43 and falls. .

Note that the present invention is not limited to the above embodiments, and various changes may be made without departing from the gist of the present invention.
