Description

  The present invention relates to a drain trap provided in a bathroom such as a unit bath, and more particularly, to a drain trap that facilitates removal of components that are removed from a main body of a drain trap and cleaned.

  For example, as shown in FIG. 6, the drainage structure of the unit bath is generally a drainage structure in which the drainage from the bathtub 107 and the drainage from the washing place 103 are joined and then connected to the drainage pipe 124. A drain trap 110 is provided in the section (drain pit).

  The drain trap 110 includes a water sealing cylinder 114 for preventing the odor and gas from the trap body 111 and the sewer pipe from entering the bathroom.

  As shown in FIG. 7, the sealing cylinder 114 is placed and fixed in the mounting flange 112 via a packing 117 for water stop and a sliding washer 118 for smooth rotation. More specifically, the sealing tube 114 is inserted into the mounting flange 112, and the flange 114d of the sealing tube 114 is passed through the contact surface notch portion 112d of the contact surface portion 112c of the mounting flange 112. When 114d is lowered to a position below the lower surface of the contact surface portion 112c and the sealing tube 114 is further rotated with the projection 114c being held between fingers, the packing 117 on the back surface of the end portion of the annular portion 114b of the sealing tube 114 is rotated. The upper surface of the contact surface portion 112c is in contact with the upper surface of the flange 114d and the lower surface of the contact surface portion 112c is contacted. The contact surface portion 112c is sandwiched between the flange 114d and the packing 117, and the sealing cylinder 114 is interposed via the mounting flange 112. The trap body 111 is hermetically attached and fixed.

  A mesh-like hair catcher 115 for collecting trash such as hair that flows out from the washing area 103 of the bathroom is mounted on the water seal 114. The hair catcher 115 is fixed to the mounting flange 112 by a lock mechanism by a rotation operation similar to that of the sealed tube in order to prevent the hair catcher 115 from floating due to pressure during drainage.

  By the way, since the sewage is always stored in the sealing tube 114, dirt and dust are likely to be attached, and this dirt or the like causes a bad odor. Moreover, in order to prevent clogging, the hair catcher 115 needs to be removed and cleaned from its original purpose.

  However, if regular cleaning is neglected and left for a long period of time, the dirt and hair may become between the sealing tube 114 and the mounting flange 112 (X portion in the figure) and / or the sealing tube as shown in the partially enlarged view of FIG. It sticks between 114 and the hair catcher 115 (Y part in the same figure), makes these stick, and makes it difficult to rotate.

  For the removal work, a protrusion 114c is provided on the upper part of the sealing tube 114, and the sealing tube 114 is rotated and removed using this as a clue. However, the protrusion 114c has a small clue area and has to be pressed with a fingertip, so that it is difficult to apply force. For this reason, when dirt or hair is fixed, extra effort is required for rotation. For example, a work such as turning a piece of wood of about 10 cm square on a protrusion and turning it using the principle of cocoon occurs.

  As an example, the hair catcher 115 is provided with a rubbing portion 115e at the center and / or a handle 115f at the outer peripheral portion, which is also rotated and removed as a clue. However, since the stagnation portion 115e is at the center of rotation, it is difficult to give a rotational force. Conversely, since the handle 115f is at the outer edge, it is too close to the side wall of the drain recess 130 of the waterproof pan 102 above the drain trap 110. There is a difficulty.

  In order to solve such a problem, a hair catcher in which a handle protrudes outward from an edge (of the hair catcher) has been proposed (see, for example, Patent Document 1).

  However, in this configuration, in order to conceal the handle when not in use, the drainage recess in which the drainage trap is installed is enlarged, so that a large area where the bather does not want to put his foot increases, and the design is not good. In addition, the removal of the sealing tube is not considered.

  An embodiment of a drain trap according to the present invention will be described with reference to the drawings. FIG. 1 illustrates the arrangement of drain traps in a unit bath 1 including a drain trap according to the present invention.

  As shown in FIG. 1, the unit bath 1 includes a waterproof pan 2, a bathtub 7, a wall panel 8, and a drain pit portion 6. In addition to these, the unit bath 1 includes a door, a ceiling panel, water supply / hot water supply facilities, etc. (not shown).

  The waterproof pan 2 is integrally formed of a resin material, and as shown in FIG. 1, a bath place in which a wash area 3 where a person can wash a body is formed on one side and a bathtub 7 is placed on the other side. Portions 4 are formed and are separated by a bank portion 5 that rises upward.

  The washing section 3 is formed so that the outer peripheral upper edge is formed at the same height, and the floor surface where the drainage flows is inclined so as to descend in a mortar shape toward the drainage pit section 6 provided in the middle part in the longitudinal direction of the bathtub 7. It becomes the flowing water surface S1.

  The bathtub installation part 4 is formed one step lower than the washing place part 3, and has a flowing water surface S <b> 2 that is inclined so that the floor surface of the drainage flows in a mortar shape toward the drain pit part 6.

  The bathtub 7 is mounted on the bathtub mounting part 4 of the waterproof pan 2 via a lower leg (not shown), and the side surface on the washing section 3 side is widened and formed on the upper part of the bathtub 7. And an apron 9 erected between the banks 5.

  A drainage recess 30 is provided on the side of the washing area 3 in the longitudinal direction of the bathtub 7, that is, at the lowest position of the washing area 3, and the drainage pit 6 is suspended from the drainage recess 30 by protruding from the back surface of the waterproof pan 2. Established. The drain pit 6 is usually covered with a trap cover 31.

  The trap cover 31 includes a substantially rectangular upper surface 31 a and leg portions 31 b provided on four sides for supporting the upper surface 31 a on the drain pit portion 6. Since the vertical and horizontal sizes of the upper surface 31a of the trap cover 31 are formed smaller than the vertical and horizontal sizes of the drain recess 30, gaps are provided between the four circumferences of the trap cover 31 and the drain recess 30, and the washing section 3 The drainage from the water flows down from this gap into the drainage pit section 6. In addition, the upper surface of the trap cover 31 is the same height as the nearby floor level, so that it is possible to prevent people from catching their feet and seeing the dust accumulated in the eye plate.

  FIG. 2 shows a longitudinal section of the drainage pit portion 6. The drainage pit 6 discharges the drainage on the waterproof pan 2 and the drainage in the bathtub 7 to the outside of the bath unit 1 in a state in which the back flow of odor is prevented. It is attached so as to protrude downward from the waterproof pan 2. The drainage pit part 6 is roughly divided into a drainage elbow 20 in charge of drainage of the bathtub mounting part 4 and a drainage trap 10 responsible for drainage of the washing place part 3.

  As shown in FIG. 2, the flange surface 21 of the drainage elbow 20 is fitted into the drainage elbow mounting opening 25 formed in the waterproof pan 2 so as to be substantially flush with the upper surface of the waterproof pan 2. Along with the upper surface of the waterproof pan 2, a water surface S2 is formed which inclines with a downward slope toward a portion located on the back side of the bank notch 5a. In this case, the bathtub drain hole 21 a of the flange surface 21 is positioned at a position facing the drain hole 7 b of the bathtub 7. On the other hand, the end opposite to the flange surface 21 is connected to the bathtub drainage water intake port 11b on the side surface of the drainage trap 10 body.

  The flange surface 21 is provided with a bathtub drain hole 21a for inserting a drainage fitting 22 connected to the bathtub 7 and a floor drain hole 21c for draining water accumulated in the bathtub mounting 4. Yes.

  Since the drainage fitting 22 connected to the drainage hole 7b of the bathtub 7 is fitted in the bathtub drainage hole 21a, the bathtub drainage is guided to the drainage trap 10 via the drainage elbow 20 and drained. Moreover, the overflow water of the bathtub 7 which flowed into the bathtub mounting part 4 is guided and drained from the floor drain hole 21b of the drain elbow 20 to the drain trap 10 like the bathtub drain. The floor drain hole 21b is equipped with a check valve 21c in order to prevent the water in the bathtub from overflowing into the bathtub mounting portion 4 due to the water pressure during bathtub drainage.

  Thus, the waste water of the bathtub mounting part 4 is once discharged | emitted from the floor surface of the bathtub 7 and the bathtub mounting part 4 through the drain elbow 20 to the drain trap 10 of the washing place part 3. FIG. .

  The drain trap 10 constitutes a main part of the drain pit 6 and is attached to the bottom surface of the drain recess 30 provided at the lowest position of the washing place 3, and the trap body 11, the mounting flange 12, A U-packing 13, a sealing cylinder 14, a hair catcher 15, and a packing 16 are included.

  As shown in FIG. 3, the trap body 11 is a cylindrical container having an upper opening, and a sealed water reservoir 11a having a predetermined height is formed at the center of the lower side, and communicates with the lower portion of the sealed water reservoir 11a. Thus, the bathtub drainage water intake port 11b to which the drainage elbow 20 that collects drainage from the bathtub mounting part 4 is connected is formed. The upper opening is a water intake through which drainage from the washing area 3 flows.

  Further, the trap body 11 is formed with a drain outlet 11c and connected to a drain pipe 24 so as to communicate with the upper side of the sealed water reservoir 11a. Furthermore, a female threaded portion 11d in which a screw is threaded is formed on the upper inner surface of the cylindrical trap body 11, and this female threaded portion 11d is threadedly engaged with a male threaded portion 12a provided on the mounting flange 12b. Is suspended from the drainage recess 30.

  A mounting flange 12 for suspending the trap body 12 from the drain recess 30 is placed on the top of the trap body 11. The mounting flange 12 includes a short cylindrical male screw portion 12a having a screw threaded on the outer periphery, a flange portion 12b extending substantially horizontally outward from the upper portion of the male screw portion 12a, and a mounting flange 12 in the middle of the male screw portion 12a. And an annular contact surface portion 12c protruding around the opening.

  As shown in FIG. 3, the mounting flange 12 is locked to the drainage recess 30 in a state in which the flange portion 12 b on the upper end side is placed on the U packing 13 attached to the opening edge of the drainage recess 30. An annular portion 14b of the sealing cylinder 14 inserted into the sealing water reservoir 11a of the main body 11 is locked on the contact surface portion 12c. Accordingly, the drain trap 10 is configured by screwing the male threaded portion 12a of the mounting flange portion 12 into the female threaded portion 11d of the trap body 11, and pressurizing the U packing 13 with the flange portion 12b of the mounting flange 12 and the trap body 11. Attached to the waterproof pan 2.

  As shown in FIGS. 3 and 4, the sealing cylinder 14 is arranged such that the lower end of the cylindrical portion 14a opened up and down is disposed in the sealed water reservoir 11a and is expanded from the upper end of the cylindrical portion 14a to the upper end side. Formed from an annular portion 14b, a position directly below the upper end of the annular portion 14b, and a plurality of flanges 14d provided on the side surface of the tubular portion 14a, and an annular packing 16 attached to the lower surface of the annular portion 14b Is done.

  In addition, a plurality of protrusions 14c are provided on the upper surface of the annular portion 14b so as to rotate the sealing tube 14 to be fixed to the mounting flange 12 and to attach the hair catcher 15 to a predetermined position. At the upper end, a latching portion 14e that projects substantially inwardly horizontally is further provided.

  Hereinafter, the attachment of the sealing cylinder 14 will be described with reference to FIGS. 3 and 4. First, the sealing cylinder 14 is inserted into the mounting flange 12 so that the lower end is disposed in the sealing water reservoir 11a. At this time, as shown in FIG. 3, the flange 14d of the sealing cylinder 14 is passed through the contact surface notch 12d of the contact surface portion 12c of the mounting flange 12, and then the flange 14d is formed on the lower surface of the contact surface portion 12c. Lower to a lower position.

  Further, when the sealing cylinder 14 is rotated, the packing 16 on the back surface of the end of the annular portion 14b contacts the upper surface of the contact surface portion 12c, and the upper surface of the flange 14d contacts the lower surface of the contact surface portion 12c. Is sandwiched between the flange 14d and the packing 16, and the sealing cylinder 14 is attached and fixed to the trap body 11 through the attachment flange 12 in an airtight manner.

  In this case, since the sealing cylinder 14 according to the present embodiment has a protrusion 14c that protrudes larger than the conventional one at the upper part of the annular portion 14b, the sealing cylinder 14 can be easily gripped with fingers and rotated without difficulty. Can do. Further, even when dirt or the like is stuck and a large force is required to rotate the sealing tube 14, it is sufficiently high so that, for example, it is possible to apply a large force by pressing the palm.

  As shown in FIGS. 3 and 4, the hair catcher 15 has a mesh portion 15 b formed in an outer ring portion 15 a placed on the top of the annular portion 14 b of the sealing tube 14, and a central portion of the mesh portion 15 b. The cylindrical inner ring portion 15c rises. Further, the outer ring portion 15 a is provided with the same number of outer ring notches 15 d as the protrusions 14 c and has a shape that can be fitted onto the protrusion 14 c of the seal tube 14, and the outer ring notches 15 d are connected to the seal tube 14. The hair catcher 15 is attached to the drain trap 10 without causing a positional shift by being externally fitted to the protrusion 14c and dropping.

  This hair catcher 15 is provided with a stagnation part 15e for removal, and this squeeze part 15e is a plate material having a substantially tear shape directed outward on the outer ring 15a so that it can be easily squeezed with a finger. It is formed. In order to remove the hair catcher 15, it is only necessary to squeeze and lift the stagnation portion 15e with a finger. Since there is no need to rotate like a conventional hair catcher, it is not necessary to apply an extra force, so a large clue is not required.

  Next, the movement of the hair catcher 15 on the sealing tube 14 will be described. FIG. 5A shows the position of the hair catcher 15 in a normal state, and the outer ring portion 15 a is housed in a predetermined position placed on the annular portion 14 a of the sealing tube 14.

  However, when the water in the bathtub 7 is drained, the water enters the drain trap 10 via the drain elbow 20, exceeds the seal height of the seal pool 11a, and lifts it to the hair catcher 15. The power to be added.

  Since the conventional hair catcher is attached with the lock mechanism by the turning operation in the locked state, the hair catcher does not float even in such a case. On the other hand, since the hair catcher 15 according to the present invention does not have such a rotation type lock mechanism, there is a possibility that the hair catcher 15 may float.

  However, as shown in FIG. 5 (b), since it is hooked by the hooking portion 14e protruding from the upper end of the protrusion 14c of the water sealing cylinder 14, it does not leave the protrusion 14c and enter a floating state.

  On the other hand, if the level is maintained as described above, the hair catcher 15 cannot be released from the external fitting state with respect to the protrusion 14c by being hooked by the hooking portion 14e. Therefore, when removing the hair catcher 15, as shown in FIG. 5 (c), if only the stagnation part 15 e side is lifted while leaving the opposite end of the stagnation part 15 e on the sealing tube 14. The horizontal projection distance between the opposed outer fitting notched portions 15d and 15d becomes shorter, in other words, shorter than the distance between the opposed projections 14c and 14c, and can be removed without being latched by the latching portion 14e. it can.

  The embodiments described above are for illustrative purposes and do not limit the scope of the invention. Accordingly, those skilled in the art can employ embodiments in which each or all of these elements are replaced by equivalents thereof, and these embodiments are also included in the scope of the present invention.

  For example, in this embodiment, a case where a bathtub is placed on a waterproof pan laid on the entire floor surface and applied to a unit bath having a so-called double waterproof pan structure in which a wall panel is provided on the outer edge of the waterproof pan is taken as an example. As explained above, it is applied to a unit bath with a so-called half structure (also called a tub with a wash basin or a wash basin integrated tub) in which the floor and bathtub of a wash basin are integrally formed on a frame and a wall panel is placed on the rim of the bathtub Of course, it can also be applied, and can also be applied in a conventional bathroom.

  Moreover, the drainage from the bathtub does not necessarily have to be able to be processed, and therefore, the bathtub drainage intake port that is a connection portion with the drainage elbow may not be provided.
