Description

The present invention relates to a hair catcher.

Conventionally, it has been known that a hair catcher is arranged in a drain trap of a bathroom or a washbasin so that hair, small dust, and the like do not flow into the drain pipe continuous from the drain trap to block the drain pipe. Since the hair is thin and long, it is entangled or caught in the hair catcher, which may take time to clean the hair catcher and collect the hair. Therefore, a technology has been proposed in which a hair catcher is provided with a water storage portion for storing water, and a drainage portion for overflowing excess water drained to the water storage portion is provided so that the hair is floated and put together (see Patent Document 1).

Patent No. 5928984

However, in the hair catcher described in the above publication, the drainage portion has a lattice shape in which a plurality of vertical ribs and horizontal ribs are formed and the intervals between the horizontal ribs are uniform, and the hair easily comes out of the openings of the lattice. That is, if the distance between the openings is too wide, the hair easily comes out of the openings of the lattice. On the other hand, if the intervals between the openings are too narrow, the drainage property and the foam breakability deteriorate.

It is an object of the present invention to provide a hair catcher in which hair does not easily slip out of the openings of the lattice, and drainage and foam breakability are not impaired, and hair is easily put together.

In order to achieve the above object, the present invention is a hair catcher having a main body (for example, main body 10 described below) into which water flowing from the surroundings toward the drain (for example, a washing place drain 101a described below) flows in, The main body section has a plurality of openings (for example, a drainage opening 23 described later), and drains a part of the water flowing into the main body section to the outside of the main body section (for example, a drainage section 2 described later). ), the drainage portion has a plurality of lateral ribs (for example, a lateral rib 22 described later) arranged adjacent to each other in an annular shape, and in the plurality of the lateral ribs, the lateral rib is close to the center of the annular shape. Adjacent lateral ribs that are arranged such that the lateral ribs that are located farther from the center of the annular shape are positioned above the lateral ribs that are positioned at a position lower than the lateral ribs that are positioned at a lower position. The distance (for example, the distance d1 described below) is wider than the distance between the adjacent lateral ribs located on the upper side (for example, the distance d4 described below).

Further, it is preferable that the interval between the adjacent horizontal ribs gradually becomes wider toward the lower side. Moreover, it is preferable that the space between the adjacent horizontal ribs forms the opening, and the areas of the openings are substantially the same.

Further, it is preferable that a water storage portion (for example, a water storage portion 3 described later) that stores a part of the water flowing into the main body portion is arranged below the drainage portion. The drainage portion has a plurality of vertical ribs that extend in the up-down direction and are provided adjacent to each other (for example, a vertical rib 21 described later), and the plurality of vertical ribs are provided in a downward direction along the inner surface of the main body portion. On the other hand, it is preferably inclined to one side.

The drainage part 2 is arranged at the upper part of the main body part 10, that is, between the upper end of the water storage part 3 and the upper end of the main body part 10. The drainage part 2 is formed along the side surface of the upper part of the main body part 10, and has a rib part 20 and a drainage opening 23 as a plurality of openings.

The rib portion 20 is formed of a thin frame arranged in a grid pattern and has a vertical rib 21 and a horizontal rib 22.

The lateral ribs 22 are a plurality of ring-shaped skeleton portions arranged at intervals in the vertical direction of the drainage unit 2. The horizontal rib 22 has a flat surface, and the flat surface is arranged along the inner peripheral surface of the main body 10. The upper end portion of the water storage portion 3 that also forms the drainage opening 23 located at the lowermost side also constitutes the horizontal rib 22.

Specifically, as shown in FIG. 4, the horizontal ribs 22 are provided with a plurality of different radii, and are arranged adjacent to each other in the radial direction of the main body 10 and coaxially with the main body 10 in an annular shape. Has been done. In the plurality of horizontal ribs 22, a position closer to the center of the annular shape, that is, a position farther from the center of the annular shape than the horizontal rib 22 arranged inside the circular main body 10 as shown in FIG. 4 in the radial direction. That is, the lateral rib 22 arranged on the outer side in the radial direction of the circular main body 10 as shown in FIG. 4 is arranged so as to be located on the upper side as shown in FIG. In addition, in FIG. 5, the hair catcher 1 is expanded and shown for convenience of explanation.

In the plurality of horizontal ribs 22, the interval between the adjacent horizontal ribs 22 located on the lower side is wider than the interval between the adjacent horizontal ribs 22 located on the upper side. The space between the adjacent horizontal ribs 22 is configured to gradually widen downward.

The distance d2 between the horizontal ribs 22 located second from the bottom is wider than the distance d3 between the horizontal ribs 22 located third from the bottom. The distance d3 between the horizontal ribs 22 located third from the bottom is wider than the distance d4 between the horizontal ribs 22 located fourth from the bottom. In this way, the distance between the horizontal ribs 22 that are adjacent to each other in the vertical direction is configured to be wider toward the bottom. On the other hand, in the circumferential direction of the horizontal rib 22, the interval between the adjacent vertical ribs 21 described later becomes smaller as it goes downward. As a result, the areas S1 to S4 (see FIG. 5) of the openings (drainage openings 23) that are spaces surrounded by the adjacent horizontal ribs 22 and the adjacent vertical ribs 21 are substantially the same regardless of the vertical positional relationship. Is configured to be. Here, “substantially the same” includes not only the case of being completely the same but also a case of slightly different due to manufacturing error or the like, and the difference in area is preferably within ±20%, and within ±10%. Is more preferable.
It means that

The vertical rib 21 is a vertically long plate-shaped member, and has a thin flat surface portion 211 having a predetermined width and a protruding portion 24 described below.
The vertical ribs 21 are a plurality of skeleton portions that extend downward from above the drainage portion 2 and are provided adjacent to each other. As shown in FIG. 4, the vertical ribs 21 are inclined to one side in the circumferential direction along the circumference of the main body 10. The vertical ribs 21 are arranged on the inner surface of the main body 10 in the clockwise direction of FIG. 4, and guide the water flow in the swirling direction S. At the same time, the vertical rib 21 is inclined to one side with respect to an imaginary line in the radial direction extending from the center of the main body 10 (see the imaginary line I1 in FIG. 4). Specifically, it is arranged so as to extend linearly so as to connect the upper end of the main body 10 (the upper end of the drainage part 2) and the upper part of the water storage part 3 and to be inclined with respect to the radial direction.

The vertical ribs 21 are arranged so that the inner surface of the water storage portion 3 and the inner surface of the vertical ribs 21 are smoothly continuous without a step. The plurality of vertical ribs 21 are formed on the entire inner surface of the main body 10 and are arranged at equal intervals. That is, since the diameter of the main body portion 10 is gradually reduced downward, the vertical ribs 21 have a large interval between the adjacent vertical ribs 21 on the upper end side of the main body portion 10 (drainage portion 2). On the upper end side of the water storage section 3, the intervals between the vertical ribs 21 adjacent to each other are narrowed, and at the same time, the intervals between the adjacent vertical ribs 21 are arranged so as to be uniform along the circumferential direction.

The vertical ribs 21 are formed so that, in the portion connected to the water storage section 3, there is no step with the water storage section 3 along the direction in which the vertical ribs 21 extend.

FIG. 5 is a side view showing the hair catcher 1. FIG. 6A is a cross-sectional view taken along the line AA of FIG. 5, and is a cross section cut at a position where the horizontal rib 22 is present. FIG. 6B is a cross-sectional view taken along the line BB of FIG. 5, and is a cross section cut at a position where the horizontal rib 22 is not provided.

As shown in FIGS. 3, 4 and FIGS. 6A and 6B, the protrusion 24 is a protrusion that protrudes toward the inner surface of the main body 10 along the longitudinal direction of the vertical rib 21. The protrusion 24 protrudes toward the inner surface with a length shorter than the length of the vertical rib 21 in the width direction. The protruding portion 24 protrudes while curving from the flat surface portion 211 of the vertical rib 21 toward the inner surface side of the main body portion 10.
The projecting portion 24 is arranged at one end of the vertical rib 21 in the width direction, and is arranged along an edge portion on the outer side in the centrifugal direction in the swirling direction S of the water flow (downstream side of the swirling direction S).
The protruding portion 24 continuously extends from the upper end of the drainage portion 2 to the upper portion of the water storage portion 3. More specifically, as shown in FIG. 3, the protruding portion 24 is formed so as to extend slightly below the lower end portion of the drainage opening 23 of the drainage portion 2 closest to the water storage portion 3. Further, the projecting portion 24 extends to the lateral rib 22 at the upper end of the main body portion 10 (the upper end of the drainage portion 2) and is formed at a position not exceeding the upper end of the main body portion 10.

The drainage openings 23 are a plurality of openings formed between the rib portions 20. Through the drain opening 23, the water drained to the washing place 101 flows into the inside of the main body portion 10 and flows out from the main body portion 10 side to the outside.

As shown in FIGS. 3 and 5, the water guiding section 4 is provided on the outer surface side of the main body section 10 near the boundary between the drainage section 2 and the water storage section 3. In detail, the water guiding portion 4 is provided on the outer surface of the main body portion 10 at a position corresponding to the upper end of the water storage portion 3. The inner surface of the main body portion 10 corresponding to the portion where the water guiding portion 4 is provided is formed smoothly and without steps. The water guiding portion 4 has a receiving surface 41, a connecting portion 42, and a water guiding opening 43.

The receiving surface 41 is a convex portion that projects outward from a position corresponding to the upper end of the water storage section 3 on the outer surface of the main body section 10, and is provided outside the water storage section 3 along the outer peripheral direction of the main body section 10. The receiving surface 41 projects in a substantially horizontal direction.

As shown in FIG. 5, the connecting portion 42 is a substantially triangular portion that connects the receiving surface 41 and the outer surface of the main body portion 10. In the connecting portion 42, one side of the triangle that is inclined is continuous with the outer surface of the main body 10, that is, the outer surface of the vertical rib 21, and the other side is continuous with the receiving surface 41, and the distal side of the receiving surface 41 side The side connecting the end and the distal end on the side of the vertical rib is the base of the triangle. The angle formed by the bottom side (the side extending from the distal end of the receiving surface 41 to the outer surface of the vertical rib 21) and the outer surface of the vertical rib 21 is an obtuse angle θ.

The water guide opening 43 is a space formed between the vertical ribs 21 adjacent to each other on the receiving surface 41, and is continuous with the drainage opening 23.

Next, the usage state of the above hair catcher 1 will be described.
When hot and cold water is used in the washing place 101 of the bathroom 100 to wash hair, for example, the hair that has fallen out flows toward the washing place drainage port 101a together with the water flow. The water collects in the drainage basin 120 arranged at the lowest position of the washing place, and drops into the bottom opening 121 of the drainage basin 120. At the bottom opening 121 of the drainage basin 120, the hair catcher 1 is arranged so as to be locked by the flange portion 122 around the bottom opening 121. A part of the water that has flowed down falls through the drainage opening 23 of the drainage unit 2 into the drainage trap 130 below and is drained through the drainage pipe 101b.

At the washing place 101, a part of the water directed to the washing place drainage port 101a flows into the main body 10 of the hair catcher 1. At this time, if the amount of water flowing into the drainage basin 120 is a predetermined amount, the vertical ribs 21 incline the inner surface of the main body portion 10 toward one side, so that part of the water flowing into the main body portion 10 Is guided by the vertical ribs 21 and flows in the direction S of turning inside the hair catcher 1.

The vertical rib 21 is provided with a protrusion 24 that protrudes toward the inner surface of the main body 10. Therefore, a plurality of hairs are formed on the protruding portions 24 of the vertical ribs 21 that are adjacent to each other, and thus a gap is formed between the hairs and the flat portion 211 of the vertical ribs 21. A water flow flows into this gap to float the hair from the inner surface of the main body 10. Since the vertical ribs 21 are arranged at equal intervals to each other, the vertical ribs 21 are attached to the inner surface of the main body 10 regardless of which drainage opening 23 the hair flows in or from which position of the opening 10a of the main body 10. Difficult to attach and turn in the same way.

Since the protruding portion 24 protrudes toward the inner surface side of the main body portion 10 and continues to the upper portion of the water storage portion 3, water flows along the vertical ribs 21 without riding over the vertical ribs 21. The water flowing along the vertical ribs 21 does not easily flow to the outside of the drainage section 2 and easily flows to the inside of the main body section 10, that is, the water storage section 3 below. As described above, since the vertical rib 21 is inclined to one side in the circumferential direction, water flows in the swirling direction S along the vertical rib 21. Since the protruding portion 24 is gently curved from the flat surface portion 211 toward the inside of the main body portion 10, it is easy to remove dirt.

Since there is no step on the inner surface of the main body portion 10 corresponding to the portion where the water guiding portion 4 is provided between the drainage portion 2 and the water storage portion 3, the hair flows while swirling along the water flow.

On the other hand, since the drainage portion 2 is provided with the drainage opening 23, most of the water that has flowed into the body portion 10 is drained from the drainage opening 23 to the outside of the body portion 10. Then, the water flows down along the outer surface of the main body 10. At this time, since the areas S1 to S4 (see FIG. 5) of the openings (drainage openings 23) are configured to be the same regardless of the vertical positional relationship, in the drainage openings 23 in the lower part of the drainage section 2, The drainage is performed without impairing the drainage property, and on the other hand, at the drainage opening 23 in the upper part of the drainage unit 2, the distance between the horizontal ribs 22 is small, so that the hair is prevented from passing through.

A receiving surface 41 of the water guiding portion 4 protruding from the outer surface is provided between the drainage portion 2 and the water storage portion 3 on the outer surface of the main body portion 10. A part of the water traveling on the outer surface of the main body 10 is received by the receiving surface 41, guided to the water guiding opening 43, and guided to the inside of the main body 10. Since the water guide opening 43 is continuous with the drainage opening 23, water flows into the water storage section 3 below the drainage section 2. The amount of water flowing into the water storage section 3 increases as compared with the case where the water guiding section 4 is not provided.

When water flows from the water guiding section 4 to the water storage section 3, water flows from the water guiding opening 43 through the drainage opening 23 to the inside from the outside. The drainage opening 23 is located between the adjacent vertical ribs 21 and the vertical ribs 21. As the water passes through the drainage opening 23 between the vertical ribs 21 that are inclined in one direction, the water becomes a swirl flow to form a water storage portion. Pour into 3. Since the direction S in which the water guided from the water guiding part 4 swirls is the same as the direction S in which the water swirled due to the inclination of the vertical ribs 21 formed on the inner surface of the drainage part 2, the water flowing from the water guiding part 4 is the same. However, the swirl flow merges with the swirl flow flowing through the vertical ribs 21 to the water storage section, and the swirl flow becomes a stronger vortex.

A connecting portion 42 is formed between the receiving surface 41 and the outside of the vertical rib 21, and the connecting portion 42 fills the space between the outer surface of the vertical rib 21 and the receiving surface 41, so that no unnecessary gap is formed. .. The angle formed by the outer surface of the vertical rib 21 and the side extending from the distal end of the receiving surface 41 of the connecting portion 42 to the outer surface of the vertical rib 21 is an obtuse angle θ, which facilitates wiping from the outside.

Since the water storage section 3 is provided with the water drain hole 33, the water in the water storage section 3 is also drained while the bathroom 100 is not in use.

According to this embodiment, the following effects are exhibited.
In the present embodiment, the hair catcher 1 is configured to include the main body portion 10 into which water flowing from the surroundings to the washing place drainage outlet 101a flows, and the main body portion 10 has a plurality of drainage openings 23 and flows into the main body portion 10.

The space between the adjacent horizontal ribs 22 located is wider than the space between the adjacent horizontal ribs 22 located on the upper side.

As a result, the distance between the horizontal ribs in the upper part of the hair catcher 1 is relatively narrower than the distance between the horizontal ribs in the lower part of the hair catcher 1, so that the hair passes through the upper part of the hair catcher 1. Can be suppressed. In addition, since the distance between the horizontal ribs in the lower part of the hair catcher 1 is configured to be relatively wider and narrower than the distance between the horizontal ribs in the upper part of the hair catcher 1, drainage and It is possible to secure the foam breaking property.

Further, in the present embodiment, the interval between the adjacent horizontal ribs 22 is gradually widened downward. This makes it possible to prevent the hair from passing through in the upper part of the drainage part 2 and to secure the drainage property and the foam breaking property in the lower part of the drainage part 2. That is, it is possible to achieve both the suppression of the hair passing through and the drainage property and the foam breakage property as a whole from the upper part to the lower part of the drainage part 2.

Further, in the present embodiment, the space between the adjacent horizontal ribs 22 constitutes an opening (drainage opening 23), and the areas of the respective openings are substantially the same. As a result, it is possible to ensure well-balanced drainage between the upper part and the lower part of the hair catcher 1.

Further, in the present embodiment, the water storage part 3 that stores a part of the water that has flowed into the main body part 10 is arranged below the drainage part 2. Thereby, the water flowing in from the water conduit 4 can be efficiently stored.
