When the cylindrical lid 40 is rotated and loosened with respect to the inlet-side screw hole 39 as shown in FIG. 6, the water stop cock 35 and the valve element 37 are separated from the inlet opening 34 and become water-permeable, as shown in FIG. Then, when the screw is screwed in, the stop cock 35 and the valve body 37 are pushed in, the inlet opening 34 is closed, and the water stops.

  The outlet chamber 32 communicates with the intermediate chamber 33 through the outlet opening 41. A drain plug 42 is provided so as to face the outlet opening 41. The drain plug 42 has a drain plug body 43 made of a cylindrical body. An inflow hole 44 is formed in a part of the cylindrical wall of the drain plug body 43, and a wire mesh mesh is formed so as to close the inflow hole 44. A filter 45 is provided.

  Also. A boss 46 is coaxially formed at one end of the drain plug body 43 and an outflow hole 47 is formed. A valve body 49 for a check valve which is urged by the spring 48 so as to normally close the outflow hole 47 to the boss 46 and is guided by the boss 43 in the longitudinal direction with respect to the drain plug body 43 is provided. Is provided.

  A circular lid 50 is fitted to the other end of the drain plug body 43. The protruding edge 51 of the circular lid 50 is fitted into the inner peripheral groove 52 of the drain plug body 43, and the drain plug body 43 can move integrally with the circular lid 50 in the longitudinal direction.

  The circular lid 50 is screwed into the outlet side screw hole 53 of the intermediate chamber 33, and a coin fitting groove 54 into which a coin can be fitted is formed on the outer surface. At the time of draining, as shown in FIG. 7, the drain plug 42 can be pulled out from the outlet chamber 32 by removing the circular lid 50 from the outlet side screw hole 53 and pulling it out.

  Although not shown in FIG. 4, a bathtub apron 55 as shown in part in FIG. Since the bathtub apron 55 and its mounting structure itself are well-known techniques, a detailed description thereof will not be given here, but the upper end of the bathtub apron 55 is engaged with the engaging portion inside the outer peripheral edge of the bathtub flange 56, and the bathtub apron is engaged. The lower portion of 55 is screwed to the floor pan 29 via a fixture 57 (see FIG. 5).

  The bathtub apron 55 is formed with an opening 58 at a position facing the water draining device 4 as shown in FIGS. The opening 58 of the bath apron 55 faces the cylindrical lid 38 of the water stop cock 35 and the circular lid 50 of the drain plug 42, and is a connecting circular-shaped dharma hole connecting two circles so that they can be operated. Is formed. Moreover, since the opening part 58 of the bathtub apron 55 is formed in the connection circular shape, it can be opened with a hole saw, and there exists an effect which can process easily and can reduce a process cost.

  A makeup cap 59 can be attached to and detached from the opening 58 of the bathtub apron 55. The decorative cap 59 is integrally formed of a synthetic resin (for example, an olefin-based thermoplastic elastomer). As shown in FIG. 8C, the cosmetic cap 59 has a substantially elliptical cosmetic cap body 60 composed of a rectangular portion and left and right semicircular portions when viewed from the front side of the washing area 27. 8 (d) and 8 (e), fitting portions 61 are formed on the inner surfaces of the left and right semicircular portions of the decorative cap body 60, respectively.

  As shown in FIGS. 8D to 8G, the fitting portion 61 has a substantially semicircular cylindrical shape protruding from the inner surface of the decorative cap 59 and is fitted along the outer peripheral surface thereof. A joint groove 62 is formed. When attaching the makeup cap 59 to the opening 58 of the bathtub apron 55, the left and right inner edges of the opening 58 of the bathtub apron 55 are fitted into the fitting grooves 62 of the fitting 61. Thereby, the makeup cap 59 can be fitted into the opening 58 of the bathtub apron 55.

(Function)
The operation of the bathroom unit 1 having the above configuration will be described below through its usage. Normally, as shown in FIG. 6, the stop cock 35 of the water draining device is opened, so that hot water supplied through the hot water piping 3 on the hot water supply side is the inlet chamber 31 of the water draining device 4. And enters the intermediate chamber 33 through the inlet opening 34.

  Further, the hot water passes through the mesh filter 45 from the intermediate chamber 33 and enters the drain plug main body 43, pushes the valve body 49 for the check valve against the spring 48, and opens the outlet chamber 32 from the outlet opening 41. Enters the hot water pipe 3 on the bathtub cleaning unit 2 side.

  When a user or the like drains the hot water pipe 3, the makeup cap 59 fitted in the opening 58 of the bathtub apron 55 is removed. Then, the outer surfaces of the cylindrical lid 38 of the water stop cock 35 and the circular lid 50 of the drain plug 42 are exposed.

  When draining the hot water pipe 3 on the outlet side (downstream side) from the water draining device 4, a coin is fitted into a coin fitting groove 40 formed on the outer surface of the cylindrical lid 38 of the water stopcock 35 to form a cylinder. By rotating the lid 38 so as to be screwed into the inlet side screw hole 39, the inlet opening 34 is closed by the valve body 37 of the water stop cock 35 as shown in FIG.

  Thus, after closing the water stop cock 35, a coin is fitted into the coin fitting groove 54 of the circular lid 50 of the drain plug 42, and the circular lid 50 is rotated in a direction to loosen from the outlet side screw hole 53. The circular lid 50 and the drain plug 42 are removed from the outlet chamber 32.

  Then, the hot water remaining in the outlet side hot water pipe 3 and the bathtub unit 2 flows out from the screw hole 53 on the outlet side by its own weight. Note that the water supply from the hot water supply unit 5 may be stopped without closing the water stop cock 35.

  When draining the hot water pipe 3 on the inlet side from the water draining device 4, the hot water supply from the hot water supply unit 5 is stopped and the water stop cock 35 is removed from the inlet side screw hole 39. The water in the pipe 3 can be discharged from the screw hole 39 on the inlet side.

  When the makeup cap 59 is attached to the opening 58 of the bathtub apron 55, the inner edges of the opening 58 of the bathtub apron 55 are fitted to the left and right fitting portions 61 of the makeup cap 59, and then fitted. Good.

  As mentioned above, although the best form for implementing the bathroom unit which concerns on this invention was demonstrated based on the Example, this invention is not limited to such an Example, It was described in the claim It goes without saying that there are various embodiments within the scope of technical matters.

  The bathroom unit according to the present invention has the above-described configuration, but includes the flow path control member of the hot water pipe 3 in the configuration of the present invention, covers this with the cover member, and faces the flow path control member. Thus, the configuration in which an opening is provided in the cover member and the decorative cap is detachably attached to the opening is not limited to a bathroom unit, and is applicable to a place having a flow path control member, such as a washroom.
