[Prior art]

 FIG. 5 is a sectional view showing a conventional bathroom drainer. This drainage device for a bathroom has a cylindrical drainage main body 51 with an upper opening and a bottom, a drainage tubular portion 52 having upper and lower openings that project vertically through the bottom surface of the drainage main body 51, and the drainage tubular portion. It consists of a water sealing cylinder 53 that fits in the upper cylindrical portion of 52 with a gap, and a drainage tray 54 fixed to the center of the upper surface of this water sealing cylinder 53 with a screw 55. In the state where the water sealing cylinder 53 is fitted in the drainer main body 51, the flat plate-shaped drainage tray 54 is placed on the upper opening peripheral flange surface 51 a of the drainer main body 51. This bathroom drainage device is fitted and fixed to a drainage prepared hole that is previously provided on the floor surface 6 of the bathroom. In this fitted and fixed state, the upper opening flange surface of the drainage main body 51 and the upper surface of the plate 54 are substantially flush with the floor surface 6. The dirty water on the floor flows into the cylindrical drainage main body 51 from a large number of drainage holes 54a formed in the surface of the plate 54, and pools on the bottom surface. When the sewage pooled on the bottom surface overflows, the sewage overflowing from the upper end of the drainage tubular portion (upper tubular portion) 52 will go through the fitting space between the upper tubular portion of the drainage tubular portion 52 and the sealing tube 53. It flows into the drainage pipe 52 and flows out to the sewage rising pipe connected to the protruding lower end of the drainage pipe 52.

[Problems to be solved by the device]

 In the above-mentioned conventional bathroom drainage device, the dirty water on the floor surface of the washing place flows into the drainage body through the plurality of drainage holes (through holes) provided in the surface of the dish. The drainage holes of the eye plate are arranged in the vertical and horizontal directions, but the load bearing load applied to the eye plate from above is too large, and from the viewpoint of aesthetics, too many holes cannot be formed. It is opened in the opened state. Therefore, the total area of the drain holes is very small compared to the area of the plate, and there is air resistance when inflowing sewage. For this reason, the inflow of sewage into the main body of drainage is limited, and when there is a large amount of sewage on the floor surface, the drainage efficiency is poor and there is a disadvantage that sewage pools on the upper surface of the plate. Further, if a large amount of sewage flows into the drainage body, the sewage overflowing into the drainage body has a disadvantage that the water sealing cylinder and the plate are lifted upward and moved in the left-right direction. Further, since the drainage holes provided in the perforated plate are arranged in the vertical and horizontal directions, the inside of the drainage body can be visually seen from above through the drainage holes, and there is a drawback that it is unclean. .

The present invention aims to solve the above problems and to provide a drainer for a bathroom which has a simple structure with a small number of parts, has a high drainage efficiency, and is hygienic and does not feel unclean. And

[0005]

[Means and Actions for Solving the Problems]

 In order to achieve this purpose, the bathroom drainer of the present invention has the following configuration. A bathroom drainer is a cylindrical drainage body with a top opening and a bottom with a horizontal flange protruding from the top opening, and a drainage tube with upper and lower openings that continue from the bottom surface of the drainage body and project vertically from the bottom surface. Section, a plurality of cap supporting and reinforcing rib pieces projecting at predetermined intervals on the peripheral wall surface of the upper cylinder section of the drainage tube section, and by being supported by the reinforcing rib pieces, the drainage main body is supported. A continuous circular drainage space opens between the fittings, and a wastewater flow channel space communicating with the drainage space opens between the peripheral wall surface of the upper cylinder part, the upper end surface of the upper cylinder part, and the bottom surface of the drainage body. It is characterized in that it is composed of a cylindrical cap body having a bottom with an opening.

In the bathroom drainer having such a configuration, in the tubular cap body fitted in the drainage main body, the top plate portion is supported by the upper end surfaces of the plurality of cap supporting and reinforcing ribs, and The inner peripheral surface is supported by the outer end surface of the reinforcing rib. In this fitted state, a circular drainage space is opened between the drainage body and the tubular cap body. Furthermore, a circular gap is formed between the bottom portion of the opening of the tubular cap body and the bottom surface of the drainage body. Further, in this fitted state, the top plate surface of the tubular cap body is substantially flush with the horizontal flange surface and the floor surface of the drainage body. Sewage on the floor opens between the top plate surface of the tubular cap body and the upper opening surface of the drainage body, and flows into the drainage body all at once from the drainage space that is continuous in a circle. The drainage space that is continuous in a circle has a drainage area larger than the sum of the areas of a plurality of drain holes that are independently provided in the surface as in the conventional case. Moreover, since the hole space is continuous, drainage efficiency is improved, and there is no risk of sewage pooling on the floor surface. Sewage that flows into the drainage body through the drainage space is pooled at the bottom of the drainage body. When the inflow of sewage in the pool becomes large and overflows, the sewage that overflows rises in the space between the outer surface of the upper tubular part of the drainage tube and the peripheral surface of the tubular cap body, and the upper end of the upper tubular part rises. From the space between the top plate surface of the tubular cap and the upper end of the upper tubular part, it flows into the upper tubular part, and flows out to the sewage rising pipe connected to the lower end of the lower tubular part of the draining tubular part. In the drainage device having such a configuration, since the drainage space which is continuous in a circle is provided around the outer periphery of the cap body, it is difficult to visually check the sewage pooled on the bottom surface of the drainage body from above, and it is hygienic and clean. Further, the tubular cap body serves both as a conventional perforated plate and a water sealing tube, has a small number of parts, and can be provided at low cost. Further, since the tubular cap body is tightly fitted to the plurality of reinforcing ribs, there is no disadvantage that it is lifted by the sewage overflowing into the drainage body.

【Example】

 FIG. 1 is an exploded perspective view showing a concrete embodiment of the bathroom drainer according to the present invention.

The drainer for a bathroom includes a cylindrical drainage main body 2 having an upper opening and a bottom, a drainage tubular portion 3 having an upper and lower surface opening protruding vertically through a bottom surface 21 of the drainage main body 2, and the drainage tubular portion 3 By supporting a plurality of cap supporting / combining reinforcing rib pieces 33 arranged on the peripheral wall surface of the upper tubular portion 32 of the upper cylindrical portion 32, and supporting by the cap supporting / combining reinforcing rib pieces 33, one round is formed during fitting with the drainage main body 2. The continuous drainage space A is opened, and the drainage space 3 and the drainage space A are connected to the drainage space A.

In the embodiment, the tubular drain main body 2 is a cylindrical body having an upper opening and a bottom, and a horizontal flange 22 is provided outwardly at the peripheral edge of the upper opening. This tubular drainage main body 2 is formed of a plastic material (for example, ABS resin material), and in the embodiment, a stainless steel plate 22a is attached to the surface of the horizontal flange 22 to beautifully decorate the appearance. In addition, a finger insertion recess 24 that is recessed inward is provided at an appropriate position on the upper opening surface (including the flange 22) of the drainage main body 2 for the convenience of taking out the cylindrical cap body 1 described later (see FIG. 2). . As shown in FIGS. 2 and 3, the drainage tubular portion 3 is a cylindrical body having upper and lower openings, and is formed in a central portion of the bottom surface 21 of the drainage main body 2 so as to project vertically and integrally so as to be integrally continuous. The drainage tubular portion 3 is composed of a lower tubular portion 31 projecting downward from the bottom surface 21 and an upper tubular portion 32 continuous with the lower tubular portion 31 and projecting upward from the bottom surface 21. The upper end surface of the upper tubular portion 32 is set so as to be positioned below the upper surface of the opening of the drainage main body 2, and the lower end of the lower tubular portion 31 projects downward more than the bottom surface 21.

As shown in FIGS. 1 and 4, the cap bearing / reinforcement rib 33 is provided in the upper tubular portion 32 of the drainage tubular portion 3. In the embodiment, six reinforcing ribs 33 are provided on the peripheral surface of the upper cylindrical portion 32, each opening at an angle of 60 °. The reinforcing rib 33 is integrally formed with the upper tubular portion 32 in the embodiment. The upper end 33c of each reinforcing rib 33 is set to a height that is substantially aligned with the upper opening surface of the drainage body 2. That is, the thickness is set to be lower than the flange surface 22 of the drainage main body 2 by the thickness of the top plate surface 11 of the tubular cap body 1 described later. Further, the lower end 33d of the reinforcing rib 33 is set to have a length in contact with the bottom surface 21 of the drainage main body 2. Further, the reinforcing rib 33 is provided in a straddle shape on the upper cylindrical portion 32, and is composed of an outer protruding portion 33a and an inward protruding portion 33b. The virtual diameter formed by the tip end surface (outer end surface) 33e of the outward protruding portion 33a of each reinforcing rib 33 is set to be substantially equal to the inner peripheral diameter of the tubular cap body 1 to be described later, and the tubular cap body 1 is set to this outer diameter. It is adapted to be tightly fitted to the tip surface 33e of the directional protrusion 33a.

As shown in FIGS. 1 and 2, the tubular cap body 1 is a tubular body with a bottom opening and a bottom. In the embodiment, the tubular cap body 1 is cylindrical and a stainless steel plate is processed by sheet metal working. Has been formed. The cylindrical cap body 1 is set to have an outer diameter smaller than the inner diameter of the drainage main body 2, and when fitted to the drainage main body 2, the inner surface of the top plate surface (bottom surface) 11 is supported by the upper end surface 33c of the reinforcing rib 33. In addition, the inner surface of the peripheral wall surface 12 is supported by the outer end surface 33e of the reinforcing rib 33. In this state, the lower peripheral end surface 12a of the tubular cap body 1 is located above the bottom surface 21 of the drainage main body 2. Further, in this fitted state, while the outer circumference of the tubular cap body 1, that is, the fitting with the drainage main body 2, the drainage space A which is continuous in a circle is opened, and the opening lower end face 12a and the bottom face 21 are formed. A sewage flow path B is provided between the sewage flow path C, the inner surface 12 of the peripheral wall and the peripheral wall surface of the upper cylinder portion 32, and a sewage flow is provided between the inner surface of the top plate surface 11 and the opening upper end surface 32b of the upper cylinder portion. Road D opens.

As shown in FIG. 2 and FIG. 3, the bathroom drainer having such a configuration is fitted and attached to, for example, a drainage prepared hole that is provided in advance on the floor surface 6 of the bathroom in the bathroom. In this state, the top plate surface 11 of the tubular cap body 1 and the flange surface 22 of the drainage main body 2 are substantially flush with the floor surface 6. Sewage on the floor flows into the drainage main body 2 from the continuous circular drainage space A. The inflowing wastewater is pooled on the bottom surface 21. That is, the bottom surface 21 and the lower opening surface 12a of the cap body 1 are pooled in the dirty water flow path space B. When the volume of the sewage increases, the water level of the sewage rises in the sewage flow path (space) C between the outer peripheral surface 32a of the upper tubular portion 32 and the peripheral wall surface 12 of the tubular cap body 1. When the sewage overflows, the sewage flows into the upper cylinder part 32 from the sewage flow path space D between the top plate surface 11 of the cap body 1 and the upper end surface 32b of the upper cylinder part 32. This sewage flows out to the sewage rising pipe 4 connected to the lower end of the lower tube portion 31. Thus, the sewage flows from the fitting space A between the drain main body 2 and the tubular cap 1 into the drain main body 2 at once. Since the fitting space A is a continuous, circular (ring-shaped) space, the drainage area is very large compared to the conventional multiple drainage holes. Furthermore, since it is a continuous ring-shaped gap, there is less air resistance when sewage flows in (air escapes smoothly), and drainage efficiency improves. Therefore, even if a large amount of sewage is washed away, it can be drained all at once and there is no risk of sewage pooling on the floor 6. Further, in the circular drainage space A along the outer periphery of the tubular cap body 1, the inside of the drainage main body 2 is hardly visible from above. Therefore, the sewage collected on the bottom surface of the drainage main body 1 cannot be seen and can maintain a sanitary appearance. Further, even if sewage overflows in the drainage main body 2, the tubular cap body 1 does not have a disadvantage such as floating and moving due to the sewage. Further, since the tubular cap body 1 also serves as a conventional plate and a water sealing tube, the number of parts is small, the structure is simple, and the drainer is inexpensive.

In the embodiment, the drain main body 2 and the tubular cap body 1 are cylindrical, respectively. However, in the embodiment, only the flange surface 22 of the drain main body 2 is a rectangular (square) flange 22. Of course, the drainage main body 2 may have a rectangular tube shape, and the tubular cap body 1 may have a rectangular tube shape.

[Effect of device]

 According to the present invention, as described above, the drainage tubular portion having the upper and lower surface openings is vertically projected through the bottom surface of the tubular drainage body having the upper opening and the peripheral wall surface of the upper tubular portion of the drainage tubular portion. A plurality of reinforcing rib pieces that also support the cap are arranged, the tubular cap supported by the reinforcing rib pieces is fitted to the drainage body, and a continuous circular shape is opened between the fitting of the drainage body and the tubular cap. Since it was decided to let the sewage on the floor flow into the main body of the drainage from the drainage space, the tubular cap doubles as a conventional perforated plate and sealing cap, has a small number of parts, and has a simple structure and an inexpensive drainer. Can be provided. In addition, since the drainage space is a continuous circle, the drainage area is large and the drainage efficiency is improved compared to the conventional multiple drainage holes. Therefore, it is possible to eliminate an unclean condition such as filthy water pooling on the floor. Further, in the circular fitting space along the outer circumference of the cap body, the dirty water pooled at the bottom of the drainage main body cannot be seen, and a sanitary appearance can be maintained. Further, even if the sewage collected at the bottom of the drainage body overflows, there is no fear that the cap body will be pushed upwards.
