The arrangement will be described.

  A sleeve portion 140 is formed on the left side of the main body 110 so as to project integrally with the main body 110, and a plurality of operation switches 141 and a display device 142 for operating each function of the sanitary washing device 100 are installed on the upper surface of the sleeve portion 140. Has been.

  A seating sensor 111 is installed on the front surface of the main body 110. The seating sensor 111 is a reflective infrared sensor, and detects the presence of a user on the toilet seat 130 by detecting infrared light reflected from the human body.

  A water supply connecting portion 112 for supplying cleaning water for cleaning the user's local portion is provided at the lower rear portion of the main body 110. As shown in FIG. 1 and FIG. 2, the water supply connection portion 112 is connected between a water stop cock 230 connected to a water pipe 220 and operated for water flow and water stop, and a water supply pipe 240 connected to a low tank 210. The connection hose 330 of the connected branch piping member 300 is connected in a watertight manner so that tap water can be supplied to the sanitary washing device 100.

Inside the main body 110, a cleaning means (not shown) for cleaning the local part of the human body, a drying device (not shown) for drying the local part after the cleaning, a deodorizing device (not shown) for deodorizing the odor during defecation, A control unit (not shown) for controlling these functions is installed, and the control unit controls each function of the sanitary washing device 100 based on the detection signal of the seating sensor 111 and the operation of the operation switch 141. .

<2> Configuration of Branch Pipe Member As shown in FIG. 3, the branch pipe member 300 includes a main body 310 formed by casting a copper alloy, a cap nut 320 made of copper alloy, and a connection made of PVC containing a PET fiber. The hose 330 is a main component.

  The main body 310 is provided with a connection port at both ends in a substantially cylindrical body portion 311 provided with a main flow path, and a C-ring (not shown) fitted into the main body 310 in a water inlet connection port 312 opened at one end portion. ) And a hexagonal cap nut 320 is rotatably locked, and a connection screw 315 is formed on the outer periphery of the water outlet port 313 opened at the other end.

  A branch portion 316 provided with a branch channel communicating with the main channel is formed in the middle portion of the body portion 311 in a direction intersecting substantially at a right angle. A branch opening (not shown) is opened at the tip of the branch part 316, and a plurality of annular protrusions (not shown) are formed on the outer periphery of a connection part (not shown) formed to have a thin outer periphery. Thus, the connection hose 330 inserted along the outer periphery of the connection portion has a shape that prevents the connection hose 330 from falling off. A fixing fitting 331 is fitted on the outer periphery of the connection hose 330 inserted into the connection portion, and the connection hose 330 is mounted so that the main body 310 does not easily fall off by caulking with a press.

  A flange 317 having a diameter larger than the outer periphery of the connection screw 315 is formed integrally with the main body 310 at the original portion of the connection screw 315 provided on the outer periphery of the water outlet connection port 313, and the connection screw 315 is damaged by a foreign matter. It is configured to prevent receiving.

  As shown in FIG. 4, a holding portion 318 having a flat surface protruding beyond the outer periphery of the flange 317 is integrally formed on both surfaces of the body portion 311 continuously with the flange 317. The width of the holding part 318 has more than half of the diameter of the body part 311, and the dimension in the length direction is longer than the center of the branch part 316 as indicated by the center line D in FIG. The holding portion 318 can prevent the main body 310 from rotating by holding the holding pipe 318 with a tool when the screw is tightened during the connection work between the branch pipe member 300 and the stop cock 230 and the water supply pipe 240. .

<3> Installation Method of Branch Piping Member As shown in FIG. 2, when installing the branch piping member 300, the branch piping member 300 and the stop cock 230 are connected as an initial stage. In this case, a cap nut 320 of the branch piping member 300 is tightened by inserting a packing (not shown) between the water inlet connection port 312 of the branch piping member 300 and the connection port (not shown) of the stop cock 230. The branch piping member 300 is fixed to the stop cock 230 by the above. By holding the holding portion 318 of the main body 310 with a tool such as a spanner or a plier from the direction of arrow B in FIG. 2 during this tightening operation, the main body 310 is prevented from being rotated and a predetermined angle is maintained.

  Next, the branch piping member 300 and the water supply pipe 240 are connected. In this case as well, branching is performed by tightening the cap nut 241 of the water supply pipe 240 with a packing (not shown) interposed between the water outlet connection port 313 of the branch pipe member 300 and the connection port (not shown) of the water supply pipe 240. The piping member 300 and the water supply pipe 240 are connected. During the tightening operation, the holding portion 318 of the main body 310 is held by a tool such as a spanner or a plier from the direction of arrow C in FIG. 2 to prevent the main body 310 from rotating and maintain a predetermined angle.

  When the connection work between the branch piping member 300, the water stop cock 230, and the water supply pipe 240 is completed, the connection hose 330 is connected to the water supply connection portion 112 of the sanitary washing device 100. Connection with the water supply connection part 112 is performed via a quick connector (not shown).

  As described above, the branch piping member 300 in the present embodiment is configured with a simple structure and a small number of members, and the connection hose 330 is connected in advance, which is low in cost and shortens the time for installation work. Is something that can be done.

  In addition, the main body 310 includes the holding portion 318, and the holding portion 318 is formed to have a considerable size, so that the main body 310 can be reliably held during both tightening operations associated with the connection of the water inlet connection port 312 and the water outlet connection port 313. Therefore, the construction accuracy can be increased, the occurrence of abnormality such as water leakage from the connection portion can be suppressed, and the workability of construction can be improved.

  In addition, by installing the sanitary washing device 100 using the branch piping member 300 of the present embodiment, the installation work can be performed in a short time with a simple work, and a highly accurate installation state can be obtained. Can do.

  In addition, although this Embodiment is the content when the diameter of the connection hose 330 or the fixing bracket 331 is smaller than the diameter of the flange 317, the diameter of the connection hose 330 or the fixing bracket 331 is larger than the diameter of the flange 317. The same effect can be obtained by forming the holding portion 318 having a flat surface protruding beyond the larger outer periphery of the connection hose 330 or the fixing bracket 331.

  As described above, the branch piping member according to the present invention can improve the low cost and workability, and therefore can be applied to uses such as piping members other than water.
