  Further, in the sanitary washing device 2, after the supply of the washing water to the supply destination selected by the operation of the flow control / flow path switching valve device 50 based on the operation on the operation unit 11 ends, the washing water accumulates in the casing 51. Draining of draining the washed water out of the casing 51 is performed. The drainage of the casing 51 is performed by opening the space communicating with the inside of the casing 51 by the operation of the vacuum breaker 24 in the state where the opening 53a of the movable disc 53 communicates with the drain port 52a of the fixed disc 52. .

  According to the flow control / flow path switching valve device 50 and the sanitary washing device 2 including the same according to the embodiment described above, water is contained in the casing 51 that houses the fixed disk 52 and the movable disk 53 as valve disks. It is possible to prevent the valve disk from remaining, and prevent propagation of bacteria in the casing 51 and breakage of the valve disk caused by freezing of water in the casing 51.

The direction can easily be obtained by the action of gravity. Thereby, the drainage speed can be increased in draining the water in the casing 51, and high drainage performance can be obtained.

  Further, in the flow control / flow path switching valve device 50 according to the present embodiment, all of the seven drainage pipe portions 54 have the direction of projection from the casing 51 along the horizontal direction.

  According to such a configuration, for example, as compared with a configuration in which the drain pipe portion 54 protrudes downward from the casing 51, the overall height of the flow control / flow path switching valve device 50 can be suppressed. The control / flow path switching valve device 50 can be made compact. This makes it possible to reduce the size of the cleaning water supply unit 12 and thus the size of the sanitary washing device 2. In addition, since all the drain pipes 54 project in the horizontal direction, the piping connected to the drain pipes 54 can be easily arranged, and the configuration of the apparatus can be simplified. Become.

  The projecting direction of the drain pipe portion 54 may be a direction inclined downward from the horizontal direction. Specifically, as shown in FIG. 11, the drain pipe portion 54 is provided to project obliquely downward with respect to the vertical side surface (the right side surface 62 f in FIG. 11) of the drain flow channel forming portion 62.

  According to such a configuration, also in the drain pipe portion 54, the washing water can be efficiently discharged by utilizing the action of gravity. Thereby, drainage in draining the water in the casing 51 can be effectively improved. Note that the projecting directions of the seven drainage pipe portions 54 may be all horizontal directions, or may be partially or wholly downwardly inclined directions as shown in FIG. 11. That is, it is only necessary that all the drain pipes 54 have the protruding direction from the casing 51 oriented in the horizontal direction or below the horizontal direction.

  Further, in the flow control / flow path switching valve device 50 according to the present embodiment, a discharge port 82 that opens to the side and communicates with the drain pipe 54 is provided at the lower end of the casing 51.

  According to such a configuration, for example, as compared with a configuration in which the discharge port 82 is opened on the lower surface of the casing 51, the overall height of the flow control / flow path switching valve device 50 can be suppressed, and the flow control / flow The path switching valve device 50 can be made compact.

And a drain passage forming portion provided with the pipe portion 54.

  According to such a configuration, for example, as compared with a configuration in which the water supply port 63f is provided on the upper surface of the casing 51, the overall height of the flow control / flow path switching valve device 50 can be suppressed, and the flow control / flow path The switching valve device 50 can be made compact. Further, it is possible to prevent the washing water flowing from the water supply port from directly colliding with the connecting portion between the motor 55 and the movable disk 53, such as the shaft support member 56, so that the stable operation of the movable disk 53 can be achieved. It can be easily secured. Further, in the casing 51, the upper portion for accommodating the disc valve mechanism and the like and the lower portion on which the plurality of drain pipes 54 are disposed can be divided into regions in the vertical direction. This makes it possible to easily realize a configuration for disposing all of the plurality of drain pipe portions 54 at a position below the valve disk, and to make the configuration of the casing 51 relatively simple. . This contributes to making the flow control / flow path switching valve device 50 compact and easy to manufacture.
