Further, although not shown or described in detail in detail, a packing for watertightly connecting the respective members is provided as necessary at the connection locations of the respective members.

The drainage pipe of the wash bowl WB provided on the wash basin W configured as described above is applied to the wash bowl WB as described below.
When performing the construction, the microphone M and the speaker S are arranged and fixed in advance in the drain port 1, the overflow drain port 2, and the opening 5 in advance. With respect to the wiring L1 of the microphone M and the speaker S, the wiring L1 of the microphone M and the speaker S installed in the drain port 1 and the opening 5 passes through the inside of the drain plug body 4 and passes from the lower end of the drain plug body 4 to the outside. It is extended. Further, the wiring L1 of the microphone M and the speaker S installed in the overflow drain port 2 passes through the overflow channel 3, and extends from the attachment port 13 into the wash bowl WB.
Further, a wiring L2 for transmitting the presence / absence of water discharge of the curan K is connected from the curan K to the silencer mechanism E in the cabinet.
From such a state, first, the microphone L from the overflow drain port 2 and the wiring L1 from the speaker S are inserted into the opening 5 on the side surface of the drain plug body 4, and further, the interior of the drain plug body 4 is passed through. Extend from the lower end of the plug body 4 to the outside. That is, the wiring L1 of all the microphones M / speakers S passes through the drain plug body 4 and extends from the lower end.
Next, the drain plug main body 4 is inserted until the flange portion 6 side faces the upper surface of the peripheral edge of the attachment port 13 with the flange portion 6 side facing upward. At this time, the lower end of the drain plug main body 4 is disposed so as to protrude into the opening of the overflow channel 3 immediately below the attachment port 13. When the female screw portion 9 of the plate nut member 8 is screwed into the male screw portion 7 of the drain plug main body 4 from this state, the periphery of the attachment port 13 (and the opening just below the attachment port 13 of the overflow channel 3).

Is connected in a water-tight manner in the extended state, and the construction of the drain pipe to the wash bowl WB is completed.

In the wash bowl WB in which the drain pipe is constructed as described above, when drainage occurs inside the wash bowl WB, the drainage from the drain port 1 to the drain plug body 4, the T-shaped pipe member 11, the trap member 10, and the connecting pipe member 12 is finally discharged from the underfloor piping to the sewage side.
In addition, when the drain port 1 is closed with a rubber plug or the like, the drainage is accumulated in the wash bowl WB, but when the water level of the drain in the wash bowl WB reaches the lower end of the overflow drain port 2, the subsequent drainage is overflow drainage. From the port 2, it passes through the overflow flow path 3 and is finally discharged from the underfloor pipe to the sewage side through the opening 5, the drain plug body 4, the T-shaped pipe member 11, the trap member 10, and the connecting pipe member 12. Is done.
Further, by using the drainage pipe as described above, the drainage is accumulated in the bent portion of the trap member 10 and a part of the pipe body is in a water-sealed state. Therefore, odors and pests from the sewage side to the indoor side Can be prevented.

Further, when water is discharged from the curan K, the silencing mechanism E connected to the wiring L2 of the curan K is activated. As a result, drainage noise is collected from the microphone M arranged in the drainage pipe 1, the drainage outlet 2, the drainage plug body 4 side opening 5 in the drainage pipe, and converted into an electrical signal. Is done. Based on this electrical signal, the silencer mechanism E connected to each microphone M by the wiring L1 generates an electrical signal corresponding to a sound wave having an opposite phase for each wiring. Furthermore, the generated electrical signals corresponding to the reverse phase are output from the speakers S, thereby generating a decaying sound that interferes with the noise of the drainage and attenuates the noise of the drainage. And the noise at the opening 5 is attenuated (decreased). (Of course, the electrical signal of the opposite phase corresponding to the electrical signal collected at the drain 1 is sent to the speaker S of the drain 1 to Similarly, the sound is output as a decaying sound with respect to the noise.Similarly, from the speaker S of the overflow drain 2, the decay sound due to the reverse phase of the noise collected by the microphone M of the overflow drain 2 is opened from the speaker S of the opening 5. (Attenuation sound due to the opposite phase of the noise collected by the microphone M of the unit 5 is output).
When the water discharge is completed and a sufficient time (about 1 minute) has passed, the function of the silencing mechanism E is stopped, and the drainage of the wash bowl WB and the accompanying silencing effect are completed.

The embodiments of the present invention are as described above, but the present invention is not limited to the above-described embodiments, and can be freely changed without departing from the scope of the present invention.
For example, in the above-described embodiment, the function of the silencer mechanism E is activated and stopped in conjunction with the water discharge of Karan K, which is a water discharge device, but instead, as shown in FIG. A sensor SE for detecting the presence of drainage is provided on the drainage pipe other than the portion where the drainage is accumulated in the drainage pipe, and the silencer is operated by detecting the presence of the drainage in the sensor SE. You may comprise.
In the embodiment shown in FIG. 3, instead of a structure in which a wiring is provided in the water discharge device, the curan, and the sound deadening mechanism section E is notified, the main pipe portion 11 a of the T-shaped pipe member 11 and the branch are arranged in the drainage pipe. A sensor SE that detects the presence of water (drainage) is provided at the intersecting portion of the pipe portion 11b, and the wiring SE of the sensor SE is connected to the silencer mechanism E via the branch pipe portion 11b. When drainage is detected, the information is notified to the silencer mechanism E (other structures are the same as those in the embodiment of FIG. 1).
When drainage is performed from the drainage port 1 or the overflow drainage port 2 and passes through the drain plug body 4 and reaches the inside of the T-tube member 11, the sensor SE detects the drainage and is connected to the wiring L3 of the sensor SE. The silencer mechanism E is activated. As a result, drainage noise is collected from the microphone M arranged in the drainage pipe 1, the drainage outlet 2, the drainage plug body 4 side opening 5 in the drainage pipe, and converted into an electrical signal. Is done. Based on this electrical signal, the silencer mechanism E connected to each microphone M by the wiring L3 generates an electrical signal corresponding to a sound wave having an opposite phase for each wiring. Furthermore, the generated electrical signals corresponding to the reverse phase are output from the speakers S, thereby generating a decaying sound that interferes with the noise of the drainage and attenuates the noise of the drainage. And the noise at the opening 5 is attenuated (decreased). (Of course, the electrical signal of the opposite phase corresponding to the electrical signal collected at the drain 1 is sent to the speaker S of the drain 1 to Similarly, the sound is output as a decaying sound with respect to the noise.Similarly, from the speaker S of the overflow drain 2, the decay sound due to the reverse phase of the noise collected by the microphone M of the overflow drain 2 is opened from the speaker S of the opening 5. (Attenuation sound due to the opposite phase of the noise collected by the microphone M of the unit 5 is output).
When the drainage is completed and a sufficient time has elapsed since the sensor SE no longer detects drainage, the function of the silencing mechanism E is stopped, and the drainage of the wash bowl WB and the accompanying silencing effect are terminated. Note that the “sufficient time” here is set appropriately as necessary. For example, when drainage approaches the end of the drainage and the drainage runs along the inner wall of the drainage pipe, a small amount of drainage occurs in the drainage pipe. Even if the sensor SE is not touched, the sensor SE may not react unless the sensor SE detects the drainage. Even if the sensor SE no longer detects the drainage, the noise mechanism is operated for about one minute to ensure that the drainage is completed. It is preferable to check.
Further, in the embodiment of FIG. 3, the sensor SE is arranged at a portion where the main pipe portion 11a and the branch pipe portion 11b of the T-shaped pipe member 11 intersect with each other. As long as it is on the drainage pipe through which drainage flows, it may be placed anywhere. The above-mentioned “portion where the drainage is collected” is a portion where the drainage pool is generated when the drainage pipe is used in a normal manner, such as a drainage pool of the trap member. Even if the sensor SE is arranged in the part, the sensor SE continues to detect the drainage. Therefore, the silencer mechanism E will continue to operate even if there is no drainage from the drainage port 1 or the overflow drainage port 2. There is a problem that the effect of arranging the SE cannot be substantially obtained.

Moreover, in the said Example, although the tank body provided with drain piping is made into the wash bowl WB of the washstand W, this invention is not limited to the said Example, A bathtub, a bathroom, a sink of a sink, etc., Of course, it does not matter if it is used for drainage piping of other tanks.
Further, it is not always necessary to provide both the drain port 1 and the overflow drain port 2, and the drain port 1 and the overflow drain port 2 may be used for the drain piping of only the drain port 1.
Further, the overflow channel 3 is not necessarily integral with the tank body as in the above-described embodiment, and the overflow channel configured by draining the overflow drain port 2 using a tube body, a hose tube, or the like. 3 may be connected to a drain pipe through which drainage from the drain port 1 passes.
