Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a lid structure for closing a cleaning port of a toilet with a cleaning port.
[0002]
[Prior art]
Conventionally, in a flush toilet, if a very large amount of foreign matter such as paper, disposable diapers, or toilet paper cores is thrown in, or if foreign matter such as a pen or mobile phone is accidentally dropped into the toilet bowl, If washing is performed, there may be a problem that foreign matter is clogged in the trap of the toilet bowl. If the toilet bowl is further washed several times in the same state, the sewage flows back to the toilet bowl portion and overflows from the bowl portion, making subsequent use impossible.
[0003]
In this way, when the foreign object becomes clogged in the trap of the flush toilet and the toilet bowl cannot be washed after that, remove the clogged foreign substance from the toilet bowl part side with a rubber cup or the like. After all the water in the flush toilet has been drained, the flush toilet itself is removed from the floor to remove foreign matter clogged in the trap, which requires a very troublesome work.
[0004]
As a measure for removing foreign matter in the trap without removing the toilet bowl even when the rubber cup or the like cannot cope with the clogging of the foreign matter in the flush toilet as described above, as shown in FIG. Thus, a flush toilet 1 provided with a cleaning port 3 communicating with the inside of the trap 2 is used.
Normally, the cleaning port 3 of the toilet bowl is blocked by the cleaning mouth lid 4, but when a foreign object is clogged in the toilet bowl, the cleaning port cover 4 is removed from the toilet bowl so that the foreign object in the toilet bowl can be removed.
[0005]
FIG. 10 shows a conventional toilet with a cleaning port, FIG. 11 is a side sectional view of a cleaning port lid 4 that closes the cleaning port 3 communicating with the trap 2, and FIG. 12 shows a front view of the cleaning port lid 4. 13 is a water supply port, and 25 is a drain port.
The cleaning mouth cover 4 includes a disc-shaped lid body 41 having three holes 42 evenly formed on the circumference, a ring-shaped packing 5, and bolts having three sets of rectangular heads (T Die bolt) 7, a nut 8, and a washer 9 fixing member. The cleaning port 3 of the toilet bowl has a flange portion 31 that extends outside the outer diameter of the cylindrical portion 33, and corresponds to the hole 42 formed in the lid body 41 on the circumference of the flange portion 31. Three U-shaped cutouts 34 are opened at the positions.
The fixing structure is such that three bolts (T-type bolts) 7 are inserted from the back side of the flange portion 31 into the U-shaped cutout portion 34 of the flange portion 31 and the three holes 42 provided in the lid body 41. The flange portion 31, the packing 5, and the lid main body 41 are fastened from the other end with the nut 8 via the washer 9 and sealed with the packing 5.
[0006]
[Problems to be solved by the invention]
The size of the allowance L of the cleaning port 3 from the toilet body 1 is preferably as small as possible considering the clothes of the toilet user and the like. Even if the margin L is the smallest, the working space S for the fixing member is required for the thickness of the flange portion 31, the packing 5, and the lid main body 41 and the back of the flange portion 41, so that it cannot be made very small.
In addition, regarding the opening / closing operation of the cleaning mouth lid 4, considering the sealing property of the packing 5, it is necessary to uniformly fasten at three or more places, and the opening / closing operation efficiency is poor.
[0007]
The present invention has been made to solve the above-mentioned problems, and an object thereof is to provide a toilet bowl cleaning palate that can reduce the size of the outlet of the cleaning opening from the toilet body and can improve the working efficiency of opening and closing the cleaning mouth lid. And

DETAILED DESCRIPTION OF THE INVENTION
In the present invention, the toilet bowl is a flush toilet bowl and can be applied to either a wall-mounted type or a floor-mounted type.
FIG. 1 is a sectional view showing an embodiment of the present invention, which is a floor-mounted flush toilet. The washing mechanism of the flush toilet 1 shown in FIG. 1 is as follows. Water is supplied to the water supply port 13 from a water supply device such as a low tank or a flush valve (both not shown), and the wash water passes through the water conduit 12 and passes through the trap 2 and is discharged as sewage through the water discharge port 25.
The trap 2 of the flush toilet 1 goes from the drain outlet 21 of the toilet bowl part 11 to the front of the toilet, rises up to the middle height of the toilet bowl part 11 to reach the highest part 22, and then descends and bends to communicate with the drain outlet 25. Configured to form.
[0015]
The cleaning port 3 is installed on the downstream side of the highest portion 22 of the trap, and is for finding and collecting a place such as a foreign substance clogged inside the trap 2 from the front of the toilet bowl. The position of the cleaning port 3 is not limited to the front of the toilet as shown in the embodiment, and may be the side or back of the toilet as long as it is a part communicating with the trap 2. The trap 2 is not limited to the embodiment.
By providing the cleaning port 3 on the downstream side of the highest portion 22 of the trap 2, when the toilet is not washed, the toilet RF does not reach the place where the cleaning port 3 is located. Therefore, even if the cleaning port lid 4 is opened at the time of non-cleaning, there is no possibility that the stored water RF flows out of the cleaning port 3 and stains the floor surface.
[0016]
FIG. 2 is a side sectional view of the cleaning mouth cover 4, and FIG. 3 is a front view of the cleaning mouth cover 4.
The cleaning mouth lid 4 includes a cap 43, a packing 5, a stopper 6, a washer 9, and a screw 71. The cap 43 is substantially bowl-shaped and has a hole 42 through which a screw 71 is inserted while forming a recess at the center.
[0017]
FIG. 4 is a rear view of the packing 5, and FIG. 5 is a cross-sectional view of the packing 5. 2, 3, 4, and 5, the packing 5 is made of a synthetic rubber such as EPDM, and includes a circular seal portion 52, a connecting portion 57 that is continuous to the seal portion 52, and a substantially rectangular shape that is continuous to the connecting portion 57. The insertion part 51 is integrally formed in a bag shape. A bellows portion 54 is provided in the middle of the connecting portion 57. The insertion part 51 into which the stopper 6 is inserted is larger in the inside than the long side of the stopper 6, and protrudes in the circumferential direction on the outer edge of the seal part 52 that is in contact with the seal surface 32 of the cleaning port 3. A portion 53 is formed. In a state of being attached to the cleaning port 3, four protrusions 56 are integrally provided on the contact portion 55 that contacts the trap inner surface 23.
[0018]
6 is a side sectional view of the fastener 6. FIG. 7 is a front view of the fastener 6. FIG. 8 is a front view of the bending member 61. FIG. 9A is a front view of the nut 65. b) is a side sectional view of the nut 65. The fastener 6 has a long side longer than the inner diameter of the cleaning port 3, a bending member 61 in which the central portion 63 is bent and protruded, and a reinforcing member 62 whose long side is approximately the same length as the bending member 61 are welded. It is integrated by the method. Further, a hexagonal hole 631 is formed at the center of the bending member 61. The outer circumference of the nut 65 is slightly smaller than that of the hexagonal hole 631, and grooves 652 are formed in the outer circumference 651 at two positions spaced apart from the thickness of the bending member 61 and perpendicular to the axial direction of the nut 65. Yes. A nut 65 is inserted into the hexagonal hole 631 of the bending member 61 of the fastener 6 and is held by the E-shaped retaining ring 66 against the groove portion 652 of the nut 65 so as to sandwich the bending member 61 from the front and back of the bending member 61. ing. Since the interval between the E-shaped retaining rings 66 holding the nut 65 is larger than the thickness of the bending member 61 and the outer periphery of the nut 65 is slightly smaller than the hexagonal hole 631 of the bending member 61, the nut 65 is hexagonal. Although the rotation with respect to the hole 631 is restricted, the nut 65 can be inclined with respect to the bending member 61 at a certain inclination angle α as shown in FIG.
Further, since the surface 67 that is inserted into the insertion portion 51 of the packing 5 and contacts the packing 5 is chamfered and further coated with soft vinyl chloride 68 or the like, the packing 5 can be used even when the fastener 6 is tightened. Will not hurt.
[0019]
The cleaning mouth cover 4 is attached to the cleaning mouth 3 as follows.
The stopper 6 is fitted into the insertion part 51 of the packing 5, and the insertion part 51 is inserted from the cleaning port 3 in a state where the packing 5 and the stopper 6 are integrated. At this time, since the bellows portion 54 is formed in the packing 5, the insertion portion 51 can be inclined obliquely, so that the insertion is easy. Since the length of the long side of the stopper 6 is larger than the inner diameter of the cleaning port 3, the packing 5 can be hooked on the inner surface 23 of the toilet trap. Next, the seal portion 52 of the packing 5 is brought into contact with the seal surface 32 of the cleaning port 3, the cap 43 is placed over the packing 5, and the hole 42 formed in the central portion of the lid body through the washer 9. Are fastened to the threaded portion 64 of the fastener 6 through the screw 71.
[0020]
The fastener 6 has a shape in which the central portion 63 of the bending member is bent, so that the distance from the cap 43 is short and the screw 71 and the screw portion 64 can be easily fastened. Further, by integrating the bending member 61 and the reinforcing member 62, the strength of the stopper 6 itself is reinforced against the fastening of the screw. The threaded portion 64 of the fastener 6 is formed by attaching a nut 65 separate from the bending member 61 so as to be inclined to some extent in the inclination direction, so that the stopper contact surface 24 of the toilet trap inner surface 23 and the cleaning port 3 Even when the sealing surface 32 is inclined, the screw 71 can be smoothly fastened to the nut 65, and it is possible to absorb the manufacturing error of the toilet.
[0021]
In addition, a convex portion 53 is formed in the circumferential direction on the outer edge portion of the seal portion 52 of the packing 5, but this is applied by the convex portion 53 rather than contacting the seal surface 32 of the cleaning port 3 with a flat portion. This is because the contact can be surely sealed even with a small screw tightening torque. Further, a protrusion 56 is provided at a contact portion 55 of the packing 5 with respect to the inner surface of the trap. As a result, even if the screw 71 is tightened and the packing 5 is pressed against the toilet trap inner surface 23, the projection 56 is first deformed, so that excessive force can be prevented from being applied to the contact portion 55 with the stopper 6.
[0022]
In the method of fixing the cleaning port lid 4 to the cleaning port 3, the fastening portion between the stopper 6 and the screw 71 of the cleaning port cover 4 is located inside the trap 2 of the toilet bowl. L can be reduced.
Even if there is a fastening member inside the trap 2 of the toilet bowl, the fastener 6 and the screw 71, which are fastening members, are accommodated in the bag structure of the packing 5, so that the sewage in the toilet trap 2 can be directly touched. Therefore, it is possible to suppress the corrosion of the fastening member.
In addition, the bellows portion 54 provided on the packing 5 facilitates attachment / detachment of the cleaning mouth cover.
In addition, since only one central part of the toilet bowl cleaning port lid needs to be fixed, the opening and closing operation of the cleaning port lid can be simplified.
[0023]
【The invention's effect】
ADVANTAGE OF THE INVENTION According to this invention, the dimension of the allowance of the cleaning mouth from a toilet bowl main body can be made small, and the cleaning mouth cover of the toilet bowl which the work efficiency of opening / closing of a cleaning mouth cover improves can be provided.
