Description

  The present invention relates to a sanitary washing apparatus that supplies washing water to a flush toilet, and more particularly, to a sanitary washing apparatus that includes a hand washing unit above a washing water tank that stores washing water.

  In general, a sanitary washing apparatus that supplies flush water to a flush toilet such as a Western-style toilet includes a flush water tank for storing flush water at the upper rear side of the flush toilet. The washing water tank provided in the sanitary washing device is covered with a tank cover, and is stored in the tank cover together with various devices constituting the sanitary washing device.

  Some of such sanitary washing apparatuses have a structure in which a hand washing unit is provided above the washing water tank. The hand-washing portion has a water discharge portion (spout) that constitutes a water discharge port that discharges water for hand washing, and a hand-washing bowl that forms a ball surface that receives water discharged from the water discharge port. The water discharged from the water discharge port is supplied to the water discharge unit by a hand-washing water supply pipe that branches from a pipe that is connected to a water supply source such as a water supply and supplies water to the cleaning water tank.

  Thus, in a sanitary washing apparatus having a hand washing unit, conventionally, a tank cover for storing a washing water tank has a split structure in order to cope with maintenance of a branch part of a hand washing pipe or a connection part to a water discharge part. Is common (see, for example, Patent Document 1).

Therefore, the back cover body 30 can be easily removed not only at the time of assembly in the manufacturing process of the sanitary washing apparatus 1 but also easily when the sanitary washing apparatus 1 is installed on the site.

  For example, as shown in FIG. 2, the sanitary washing device 1 is installed with respect to the wall 51 in a state where only a small space exists between the rear surface portion 20 b of the tank cover body 20 and the wall 51. However, the back cover body 30 can be easily removed by an operation from above the tank cover 4 with the tool 50 as described above. Thus, according to the structure which the back cover body 30 has the latching recessed part 31, regardless of the installation condition of the sanitary washing apparatus 1, the back cover body 30 can be removed easily. Therefore, regardless of the installation status of the sanitary washing device 1, maintenance inside the tank cover 4 from the opening 21 that is blocked by the back cover body 30 can be easily performed.

  The attachment of the back cover body 30 to the opening 21 can be easily performed by the above-described attachment method if there is enough space on the rear side of the tank cover 4 to allow the back cover body 30 to be removed. Can do. Here, the locking recess 31 may be used for the operation of pressing the back cover body 30 against the tank cover main body 20 in order to lock the locking claw 30 b to the opening 21.

  Thus, in the sanitary washing device 1 of the present embodiment, for example, even in a situation where the sanitary washing device 1 is installed at a position where the back side of the tank cover 4 is close to the wall 51 at the installation site, The attachment / detachment work can be easily performed, and the maintenance work inside the tank cover 4 from the opening 21 can be easily performed.

  The locking recess 31 for removing the back cover body 30 is a portion provided in the back cover body 30 located on the back side of the tank cover 4. For this reason, since the latching recessed part 31 does not enter the view from the front at the time of normal use by a user, the outstanding external appearance design property by the tank cover main body 20 is ensured. Further, the locking recess 31 does not enter the field of view from the front during normal use by the user, and the tool 50 or the like is required to remove the back cover body 30 by the locking recess 31. 30 is not inadvertently removed.

  The back cover body 30 according to the present embodiment is a process in which the tank cover body 20 to which the back cover body 30 is attached is assembled so as to cover the cleaning water tank 3 by the tank cover part 22 (hereinafter referred to as “cover assembly process”). )), As described above, has a configuration for guiding the water supply pipe 10 provided upright by the support stay 19 (hereinafter referred to as “water supply pipe guide configuration”).

The guide rib 32 is a plate-like portion formed substantially perpendicular to the plate surface of the plate-like back cover body 30 in the inner side surface portion 30 d of the back cover body 30. The guide rib 32 rises as the water supply pipe 10 rises as the tank cover body 20 is covered with the cleaning water tank 3 from above and the rear cover body 30 moves relative to the water supply pipe 10 from the upper side to the lower side. The water supply pipe 10 is guided by making use of the flexibility of the water supply pipe 10 by contacting the portion.

  The guide rib 32 forms a passage in the vertical direction (longitudinal direction of the back cover body 30) on the inner surface of the back cover body 30 by a pair of rib portions 32a and 32b formed so as to face in the left-right direction. Specifically, as shown in FIG. 9, the guide rib 32 includes a wide portion 32c, a reduced portion 32d, and a narrow portion 32e from the lower side as portions formed by the left and right rib portions 32a and 32b.

  The wide portion 32c is formed by the lower ends of the rib portions 32a and 32b. The wide portion 32c is formed at the lower end portion of the inner side surface portion 30d of the back cover body 30 by lower rib portions 32f that face each other in the left-right direction along the vertical direction of the back cover body 30. The wide portion 32c is a portion for guiding the water supply pipe 10 into the guide rib 32 from the distal end side in the cover assembling process.

  The reduced portion 32d is formed by a portion above the lower rib portion 32f of both the rib portions 32a and 32b. The reduced portion 32d is formed by a middle rib portion 32g that is inclined so that the distance between the left and right rib portions 32a and 32b (the width of the passage of the guide rib 32, the horizontal dimension in FIG. 9) gradually decreases toward the upper side. The The reduced portion 32d is a portion for introducing the water supply pipe 10 drawn into the guide rib 32 by the wide portion 32c toward the central portion in the left-right direction in the cover assembly process. Therefore, the interval between the middle rib portions 32g constituting the reduced portion 32d is gradually narrowed from the wide portion 32c portion toward the center portion in the left-right direction from the upper portion. In the present embodiment, the pair of middle rib portions 32g constituting the reduced portion 32d is formed in a shape along the hypotenuses on both sides of an isosceles triangle shape when viewed from the front (see FIG. 9).

  The narrow portion 32e is formed by a portion above the middle rib portion 32g of both the rib portions 32a and 32b. The narrow portion 32e is formed at the lower end portion of the inner side surface portion 30d of the back cover body 30 by upper rib portions 32h that face each other in the left-right direction along the vertical direction of the back cover body 30. The narrow portion 32e is a portion for regulating the posture of the water supply pipe 10 introduced by the reduction portion 32d so as to be along the vertical direction of the back cover body 30 in the cover assembly process. For this reason, the space | interval between the left and right upper rib parts 32h which comprise the narrow part 32e is made comparatively small corresponding to the thickness (outer diameter) of the water supply pipe 10, etc. In the present embodiment, the pair of upper rib portions 32h constituting the narrow portion 32e is configured such that the water supply pipe 10 covered at least by the hose cover 10a is at the pair of the upper rib portions 32h at the center position in the left-right direction of the back cover body 30.
