Description

The present invention relates to a drain socket and a toilet bowl with a drain socket.

2. Description of the Related Art Conventionally, there is known a drain socket that connects a drain pipe portion of a toilet bowl and a drain pipe provided on a floor surface, a wall surface, or the like. For example, the drainage socket described in Patent Literature 1 below includes a drainage socket body and a height adjustment section for adjusting the height position of the drainage socket body. The drain socket main body has a first connection portion into which the drain pipe portion of the toilet bowl is inserted, and a second connection portion into which the drain pipe of the wall surface is inserted. The height adjuster vertically adjusts the height position of the drain socket body so that the drain pipe on the wall surface and the second connection part are at substantially the same height. The higher the position of the drain pipe on the wall surface, the higher the first connection part is positioned, so the drain pipe part of the toilet bowl penetrates deeper into the first connection part. The lower the position of the drain pipe on the wall surface, the lower the first connecting part is positioned, so that the drain pipe part of the toilet is shallow and enters the first connecting part.

However, in the above configuration, there is a problem that it is difficult to make the drainage property and the water stopping property constant. This is because if the fitting depth between the drain pipe portion of the toilet bowl and the first connecting portion of the drain socket body is large, the drain channel may become narrow and the ease of flow may decrease, and the fitting depth is small. This is because, in such a case, there is a possibility that the water cutoff between the drain pipe portion of the toilet bowl and the first connection portion cannot be ensured. In order to maintain constant drainage performance and water stoppage using a drainage socket with such a configuration, it is necessary to prepare a toilet bowl with a different height position for the drainage pipe according to the height position of the drainage pipe on the wall surface. be.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a drain socket and a toilet bowl equipped with the drain socket that can maintain constant drainage performance and water stoppage.

The drainage socket of the present invention includes a first connection portion connected to a drainage pipe portion of a toilet bowl, a second connection portion connected to a drainage pipe provided on a floor surface or a wall surface, the first connection portion and the second connection portion. and a drainage channel provided between two connecting portions, the drain socket comprising a socket body and a mounting part detachable from the socket body, wherein the socket body includes the second connecting portion; The drain channel and a main body end that constitutes the first connection part in a state in which the attachment part is not attached, and the attachment part has a first end detachable from the main body end. and a second end located above the first end when the first end is attached to the main body end and forming the first connecting portion.
A toilet bowl with a drain socket of the present invention comprises a toilet bowl having a drain pipe portion of the toilet bowl and the drain socket.

According to the present invention, when the attachment part is attached to the socket body, the position of the first connection portion is higher than when only the socket body is attached. Therefore, depending on the presence or absence of the mounting part, the fitting depth between the drain pipe portion and the first connection portion of the toilet bowl can be made constant. Aqueous property can be kept constant.

Preferred embodiments of the present invention are shown below.
In the drainage socket of the present invention, the second connecting portion is connected to the drainage pipe provided on the wall surface, and the drainage socket is provided with a height adjustment portion for adjusting the height position of the socket body. good too. Generally, in the case of wall drainage, there are several patterns of drainage height (height position of drainage pipe). According to the configuration of the present invention, the height adjustment portion can match the height position of the drainage pipe provided on the wall surface with the height position of the second connection portion for several patterns with different drainage heights. . In addition, depending on the presence or absence of the attachment part, the fitting depth between the drain pipe portion of the toilet bowl and the first connection portion can be made constant. Therefore, it is possible to keep the drainage performance and the water cut-off property constant without preparing toilet bowls having different height positions of the drain pipe portion.

Further, in the drainage socket of the present invention, the socket body may have a throttle portion downstream of the main body end portion, and the attachment component may have a throttle portion downstream of the second end portion. . According to such a configuration, regardless of the presence or absence of the attachment part, the water is accumulated in the constricted portion to generate a siphon effect, so that the drainage performance can be improved.

Further, in the drainage socket of the present invention, the constricted portion of the socket body and the constricted portion of the mounting part may have the same shape. According to such a configuration, the strength of the siphon force is the same regardless of the presence or absence of the attachment parts, so the drainage performance can be stabilized.

Further, in the drainage socket of the present invention, the attachment part has an insertion part inserted inside the constricted part of the main body end part, and when the insertion part is inserted into the main body end part, the main body end part is closed. The wall surface of the insertion portion may be aligned with the wall surface of the insertion portion. Here, when the mounting part is attached to the socket body, if the step of the narrowed portion of the socket body remains as it is, paper or the like is likely to get caught on the narrowed portion. However, according to the configuration of the present invention, the insertion part of the mounting part is inserted inside the narrowed part of the socket body, and the stepped part of the narrowed part of the socket body is eliminated, so papers are less likely to get caught on the narrowed part.

The lowermost portion 107 of the drainage channel lower surface 105 where the bent portion 19 turns into the ascending portion 21 is shifted rearward from the uppermost portion 108, as shown in FIG. A downward slope 109 of the lower surface 105 of the drainage channel continues to the lowermost portion 107 of the lower surface. That is, the downward slope portion 109 continues from the position D just below the lowermost portion 108 of the upper surface to the rear side. As a result, the radius of the cross-sectional shape of the downward slope portion 109 in the front-rear direction is increased, so that paper or the like can be easily bent.

An upwardly inclined portion 110 is formed on the downstream side of the lowermost portion 107 of the drainage channel lower surface 105 . The ascending inclined portion 110 has a first inclined surface 111 that bulges outward in an arc shape and curves upward, and a second inclined surface 112 that gently ascends toward the rear end. The first inclined surface 111 is formed in a region from the lowermost portion 107 to the upstream end of the second connecting portion 12 . The second inclined surface 112 is formed on the lower surface of the second connection portion 12 (the region from the upstream end to the downstream end of the second connection portion 12). The second inclined surface 112 continues from the rear end of the first inclined surface 111 . This makes it difficult for paper or the like to jam on the downstream side of the lowermost portion 107 .

As described above, in the drainage socket 100 of the present embodiment, the cross-sectional area of the drainage channel 13 and the radius of the downward slope portion 109 of the drainage channel 13 are large, so that paper or the like is easily bent. In addition, since the upward slope 110 continues to the downstream end of the second connection portion 12 on the downstream side of the downward slope 109, the paper or the like is discharged smoothly. Therefore, it is possible to prevent clogging of the drainage path 13 of the drainage socket 100 due to failure of the paper or the like to bend.
