Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
As shown in FIG. 1, the toilet device 1 shown in this embodiment is a floor-standing toilet device in which the toilet 2 is installed on the floor surface f1. The toilet device 1 includes a toilet 2 and a toilet cleaning device 3. In the following description, the front-rear direction when viewed from the user seated on the toilet 2 is defined as the front-rear direction. Further, the left-right direction when viewed from the user seated on the toilet bowl 2 is defined as the width direction. Furthermore, let the up-down direction along the perpendicular direction with respect to the floor surface in which the toilet bowl 2 is installed be an up-down direction.

  The toilet bowl 2 is installed on the floor surface f1 close to the standing wall surface f2. The toilet bowl 2 includes a toilet seat 22 and a toilet lid 23 that are rotatably attached to an upper portion of the toilet bowl body 21, and a toilet seat device function unit 24 that is disposed behind the toilet seat 22 and the toilet lid 23. Yes. The toilet body 21 shown in the present embodiment is made of earthenware made of a fired product. Side covers 211 are detachably attached to both side surfaces of the rear portion of the toilet body 21 by hook-and-loop fasteners or the like, respectively, and shield the rear portion of the toilet body 21.

The toilet bowl cleaning device 3 is arranged behind the toilet bowl body 21. The toilet bowl cleaning device 3 includes a toilet bowl cleaning tank 4 and a tank cover 5 that is an exterior body of the toilet bowl cleaning tank 4.
As shown in FIG. 3, the toilet bowl cleaning tank 4 includes a tank body 41, an inner lid 42, a base plate 43, a dewproof material 44, and a reinforcing frame 45.

  The tank body 41 is made of a blow molded product. The upper surface opening 411 (see FIG. 2) of the blown tank body 41 is formed by cutting the upper part of the blow molded product in a substantially horizontal direction. For this reason, the blow molded product can be molded by releasing in the front-rear direction, and there is no need to provide a draft angle for releasing like the injection molded product in the vertical direction. As a result, the outer peripheral surface of the tank main body 41 becomes a straight surface along the vertical direction, and can constitute a side wall surface extending perpendicularly to the floor surface. For this reason, the tank body 41 is less likely to reduce the tank volume due to the draft, and even if the depth dimension is reduced to make it thinner, it is possible to ensure a larger tank volume than the injection molded product. As a result, the toilet device 1 including the toilet cleaning tank 4 having the tank body 41 can reduce the size in the front-rear direction (the above-mentioned size).

  Wash water is stored inside the tank main body 41, and as shown in FIG. 2, internal parts for toilet flushing are accommodated. Specifically, in the tank body 41, a ball tap 4a for supplying water, a float 4b for stopping the water of the ball tap 4a, an overflow for limiting the water level of washing water and supplying makeup water to the toilet body 21 A pipe 4c, a flapper valve 4d for opening and closing the drain port, a ball chain 4e for lifting the flapper valve 4d, a pulling arm 4f for pulling up the ball chain 4e, and the like are accommodated. A spindle 4h of a lever handle 4g attached to the outside of the tank cover 5 is connected to the pull arm 4f.

  The inner lid 42 is provided so as to cover the upper surface opening 411 of the tank body 41. The inner lid 42 includes an inner lid body 421 and an inspection lid 422. The inner lid body 421 is mounted along the entire circumference of the upper surface opening 411 and is screwed to the tank body 41. On the other hand, the inspection lid 422 is not screwed to the tank body 41 and is detachably attached to the inner lid body 421. Therefore, the inner lid 42 can access the inside of the tank main body 41 without removing the screwed inner lid main body 421 by removing the inspection lid 422 from the inner lid main body 421.

  The base plate 43 is attached to the lower part of the tank body 41. The base plate 43 shown in the present embodiment is formed of a resin that is harder than the tank body 41 and has a planar shape that is substantially equal to the bottom shape of the tank body 41. The base plate 43 supports the lower surface of the tank body 41 and is fixed to the upper surface 21a on the rear side of the toilet body 21 by a pair of tightening bolts 431 (see FIG. 3) protruding from the bottom of the base plate 43, thereby It has a function of fixing the main body 41 to the toilet body 21.

  The attachment structure of the tank body 41 and the base plate 43 is shown in FIG. A circular lower surface opening 413 is formed on the bottom surface 412 of the tank body 41. A substantially cylindrical valve seat 46 is attached to the lower surface opening 413. The valve seat 46 is a component that constitutes a valve seat of a flapper valve 4d (not shown in FIG. 4) that is one of the internal components of the tank body 41, and has a flange portion 461 that is larger in diameter than the lower surface opening 413. have. The valve seat 46 is mounted from the inside of the tank body 41 with a packing 46 a sandwiched between the flange portion 461 and the tank body 41.

  The valve seat 46 integrally has a cylindrical portion 462 having an external thread on the outer peripheral surface on the lower side of the flange portion 461, and the cylindrical portion 462 protrudes downward from the lower surface opening 413. The valve seat 46 is attached to the tank body 41 by screwing a tightening nut 46b from the outside of the tank body 41 to a cylindrical portion 462 protruding from the lower surface opening 413.

  On the other hand, a circular opening 432 is provided in the central portion of the base plate 43, and a cylindrical portion 462 of the valve seat 46 that protrudes from the lower surface of the tank body 41 is inserted into the opening 432. The base plate 43 is sandwiched between the tightening nut 46c and the tank body 41 by screwing the tightening nut 46c into the cylindrical portion 462 projecting downward from the opening 432. Thereby, the base plate 43 is fixed to the lower part of the tank body 41.

  The base plate 43 fixed to the tank body 41 is fixed by inserting a pair of tightening bolts 431 protruding from the lower surface into a tank mounting hole (not shown) provided in the toilet body 21. Thereby, the tank main body 41 is fixed to the toilet main body 21 via the base plate 43. The cylindrical portion 462 of the tank main body 41 fixed to the toilet main body 21 communicates with a flush water inlet (not shown) of the toilet main body 21 so that flush water in the tank main body 41 can be supplied to the toilet main body 21.

  The dewproof material 44 is formed in a shape along the outer peripheral surface of the tank main body 41 with a polystyrene foam resin or the like. The dew proof material 44 shown in this embodiment is divided into a front dew proof material 441 and a rear dew proof material 442, and is mounted on the outer peripheral surface of the tank main body 41 so as to sandwich the tank main body 41 from the front-rear direction. . The dewproof material 44 has a height corresponding to at least the level of the cleaning water stored in the tank body 41.

  The dew proof material 44 is divided into a front dew proof material 441 and a rear dew proof material 442 in two in the front-rear direction, so that a draft angle for releasing from the mold is provided in the front-rear direction, and the vertical direction There is no draft angle. As a result, the dew proof material 44 configured by combining the front dew proof material 441 and the rear dew proof material 442 has a surface extending vertically along the vertical direction on the front surface side and the rear surface side of the toilet bowl washing tank 4. Can be formed. As a result, even if the toilet bowl cleaning tank 4 is made thinner, there is no risk of reducing the tank volume of the toilet bowl cleaning tank 4 due to the draft of the dewproof material. Moreover, combined with the fact that the tank body 41 shown in the present embodiment is not provided with a draft in the vertical direction, the toilet cleaning tank 4 can be further reduced in thickness, and the It is possible to further reduce the dimension in the direction (the above-mentioned dimension).

  As shown in FIG. 3, the reinforcing frame 45 shown in the present embodiment extends in the width direction to the metal side frame members 451 disposed on both side surfaces of the toilet flushing tank 4 and the front side of the toilet flushing tank 4. And a metal reinforcement stay 452 disposed on the surface. In FIG. 3, the toilet body 21 is indicated by a broken line, and the toilet seat 22, the toilet lid 23, and the functional unit 24 of the toilet device are not illustrated on the toilet body 21.

  The side frame member 451 corresponds to the support member of the present invention. The side frame members 451 are fixed to both end surfaces 43a (see FIG. 3) of the base plate 43 in the width direction by fixing screws 45a. Thereby, the side surface frame member 451 is indirectly attached to the toilet bowl body 21 via the base plate 43 of the toilet bowl cleaning tank 4. The side surface frame member 451 is disposed so as to cover the side surface of the toilet bowl cleaning tank 4 in a range extending from the base plate 43 to approximately half the height of the tank body 41. The side frame member 451 is formed in a U shape in plan view, and is attached to the base plate 43 so that the front dew proof material 441 and the rear dew proof material 442 do not open in the front-rear direction. The dewproof material 44 is sandwiched from the front-rear direction. The side frame member 451 corresponds to the frame member of the present invention.

  As shown in FIG. 5, the lower end portion 451 a of the side surface frame member 451 is not covered by the rear cover 52, and protrudes below the rear cover 52 and the base plate 43. The lower end portion 451a is an attachment portion for the lower cover 54 described later. Here, two screw holes 451b and one boss hole 451c are formed between them.

  Both ends of the reinforcing stay 452 are fixed to the left and right side frame members 451 by fixing screws 45b. As a result, the left and right side frame members 451 are connected to each other by the reinforcing stays 452, and the side frame members 451 are prevented from spreading in the left and right directions due to springback or the like generated in the side frame members 451.

  The reinforcing frame 45 functions so that when the user leans against the tank cover 5, the load is received and the load is not directly applied to the tank body 41. A load acting on the reinforcing stay 452 is transmitted from both ends of the reinforcing stay 452 to each side frame member 451. Since the side frame member 451 is fixed to the base plate 43 that is more robust than the tank body 41, the side frame member 451 can effectively receive the load transmitted from the reinforcing stay 452 and escape to the toilet body 21 via the base plate 43.

  As shown in FIGS. 1 to 3, the tank cover 5 includes a front cover 51 that covers the front of the toilet cleaning tank 4, a rear cover 52 that covers the side and rear of the toilet cleaning tank 4, and an upper portion of the toilet cleaning tank 4. And an upper cover 53 for covering. The front cover 51 is disposed above the toilet body 21 and is disposed between the functional portion 24 of the toilet seat device on the toilet body 21 and the toilet cleaning tank 4.

  The rear cover 52 has substantially the same height as the toilet cleaning tank 4. The rear cover 52 is screwed to the side frame members 451 provided on both sides of the toilet flushing tank 4 by fixing screws 52a. The front cover 51 and the upper cover 53 are detachable from the rear cover 52. Thereby, the tank cover 5 shown in this embodiment is indirectly fixed to the toilet body 21 via the side frame member 451 and the base plate 43. Moreover, since the entire toilet bowl cleaning tank 4 is shielded by the tank cover 5, the appearance is improved and the design is improved.

  Further, since the lower space S of the toilet bowl cleaning tank 4 is covered by the lower cover 54, the piping component 100 (see FIG. 3) arranged behind the toilet bowl 2 is blindfolded, and the rear side of the toilet bowl 2 is flushed with the toilet bowl. The shape is unified into a thin, substantially rectangular shape extending downward from the device 3, and the design is further improved. Details of the lower cover 54 will be described later.

  Since the front cover 51 of the tank cover 5 is removable with respect to the rear cover 52, when the toilet cleaning tank 4 is maintained, the toilet cover 4 can be easily accessed by removing the front cover 51. . At this time, since it is not necessary to remove the toilet bowl cleaning tank 4 itself from the toilet body 21, the maintenance work can be easily performed.

  The front cover 51 shown in the present embodiment is detachably provided upward with respect to the rear cover 52. As a result, the front cover 51 is removed while the toilet seat 22, the toilet lid 23 and the functional unit 24 of the toilet seat device disposed on the lower front side of the tank cover 5 are attached to the toilet bowl body 21, so that the toilet cleaning tank 4 can be removed. Access becomes possible, and the maintainability of the toilet bowl cleaning tank 4 can be further improved.

Here, an engagement structure between the front cover 51 and the rear cover 52 of the tank cover 5 shown in the present embodiment will be described with reference to FIGS.
First, as shown in FIG. 6, on the outside of two front end portions 521 (only one front end portion 521 is shown in FIG. 6) of the rear cover 52, a front protrusion portion 522 and a rear protrusion portion along the vertical direction. 523 is provided. The front protrusion 522 and the rear protrusion 523 are parallel. Of these, the rear ridge 523 is formed over substantially the entire length of the rear cover 52 in the vertical direction, whereas the front ridge 522 is spaced at a certain interval in the vertical direction of the rear cover 52. Are divided into multiple parts. As a result, a groove 524 is formed between the front ridge portion 522 and the rear ridge portion 523 only at a portion where the front ridge portion 522 is provided outside the front end portion 521 of the rear cover 52. The

  On the other hand, as shown in FIG. 7, the front cover 51 is formed to be slightly wider than the rear cover 52, and thus has an overhang shape that protrudes to both sides of the rear cover 52. Thereby, when the toilet device 1 is viewed from the front (observed from the front side), the rear cover 52 is covered with the front cover 51 and does not protrude from both sides of the front cover 51, so that the appearance is improved. Moreover, as shown in FIG. 1, the upper portion of the front cover 51 is also formed so as to protrude slightly above the rear cover 52, and also covers the height direction of the rear cover 52. For this reason, since the entire rear cover 52 is covered with the back surface of the front cover 51, the design of the toilet device 1 is further improved.

  As shown in FIG. 7, the front cover 51 has outer peripheral ribs 511 extending from both end edges in the width direction to the upper end edge. The outer peripheral rib 511 protrudes rearward so as to cover the groove 524 of the front end 521 of the rear cover 52. Among these, a plurality of engaging protrusions 512 that can be engaged with the grooves 524 of the rear cover 52 are formed at intervals in the vertical direction on the inner side of the outer peripheral ribs 511a arranged at both ends in the width direction of the front cover 51. ing. The length of one engagement projection 512 in the vertical direction is slightly shorter than the interval between the front ridge portions 522 adjacent to the top and bottom of the rear cover 52.

  When attaching the front cover 51 to the rear cover 52, the engagement protrusion 512 is brought into contact with the rear protrusion 523 through the space between the upper and lower adjacent front protrusions 522, and then the rear protrusion is formed. As shown in FIG. 8, the engagement protrusion 512 of the front cover 51 is engaged with the groove 524 between the front protrusion 522 and the rear protrusion 523 by sliding downward along the line 523. Let Thereby, the front cover 51 is attached to the rear cover 52 so as to be slidable upward. The attachment and removal of the front cover 51 can be performed by passing the engaging protrusions 512 of the front cover 51 between the front protrusions 522 adjacent to each other in the vertical direction. The moving stroke can be shortened.

  Since the engagement protrusion 512 of the front cover 51 is provided on the inner side of the outer peripheral rib 511 a, sink marks resulting from the provision of the engagement protrusion 512 are not formed on the front surface of the front cover 51. Will also be good. Furthermore, since the engaging part of the front cover 51 and the rear cover 52 can be covered by the outer peripheral rib 511a of the front cover 51, the appearance from the side of the toilet device 1 is also good.

  The front cover 51 attached to the rear cover 52 is attached above the rear cover 52 using a pair of attachment pieces 513 provided on the back surface of the front cover 51. Specifically, as shown in FIG. 9, a front cover attaching portion 525 is provided at a position above the toilet bowl 4 at the upper end portion of the front end portion 521 of the rear cover 52. The front cover 51 is fixed by a fixing screw 51a with the mounting piece 513 brought into contact with the front cover mounting portion 525 of the rear cover 52. For this reason, it is possible to remove the front cover 51 by removing the fixing screw 51a above the toilet cleaning tank 4 while the toilet cleaning tank 4 is fixed to the toilet main body 21. Thereby, the replacement | exchange and design change of the front cover 51 can be performed easily.

  Further, since the front cover 51 is separate from the rear cover 52, the color of the front cover 51 and the color of the rear cover 52 can be made different. For example, the front cover 51 can be given a floating feeling by making the rear cover 52 darker than the front cover 51 to provide a lightness difference, and the design can be further improved. Further, the materials of the front cover 51 and the rear cover 52 can be different.

  The upper cover 53 is attached to the upper portion of the rear cover 52 after the front cover 51 is fixed to the rear cover 52. As shown in FIGS. 10 and 11, a central portion of the front end of the upper cover 53 has a protruding portion 531 that protrudes upward. On the other hand, at the center of the outer peripheral rib 511b on the upper end side of the front cover 51, the inner end side of the outer peripheral rib 511b is further bent downward as shown in FIGS. An accommodation groove 515 for accommodating the protruding portion 531 is formed.

  The upper cover 53 is mounted on the upper portion of the rear cover 52 by accommodating the protruding portion 531 in the accommodation groove 515 of the front cover 51. Thereafter, the upper cover 53 is fixed to a screw hole 526 provided at the upper end of the front end portion 521 of the rear cover 52 by a fixing screw 53a. Thereby, since the upper end part of the front cover 51 engages with the upper cover 53, the front cover 51 is prevented from coming off to the front. Note that, as shown in FIGS. 10 and 11, the upper surface of the upper cover 53 is inclined downward toward the rear. Since the upper end portion of the front cover 51 extends so as to cover the upper cover 53 on the back side, the upper cover 53 is also difficult to see from the front side of the toilet device 1.

  In the tank cover 5 configured as described above, when removing the front cover 51, as shown in FIG. 10, first, after removing the upper cover 53 from the upper part of the rear cover 52, the fixing screw 51a of the front cover 51 is removed. Remove. Thereafter, by sliding the front cover 51 upward, the front side of the toilet flushing tank 4 can be opened and maintenance can be performed.

Next, the lower cover 54 will be described.
A pair of lower covers 54 shown in the present embodiment is provided in the toilet device 1. That is, as shown in FIG. 3, the lower cover 54 is disposed below the toilet cleaning tank 4 and on the left and right of the rear part of the toilet body 21.

Since the pair of lower covers 54 have substantially the same configuration, a specific configuration of one lower cover 54 (the lower cover 54 disposed on the left side of the toilet device 1 as viewed from the user) will be described with reference to FIG. explain.
The lower cover 54 shown in this embodiment includes a side cover 541 and a front cover 542. The side cover 541 is a plate that covers the side of the lower space S of the toilet cleaning tank 4, and the front cover 542 is a plate that covers the front of the lower space S of the toilet cleaning tank 4.

  The side cover 541 and the front cover 542 are integrally combined so as to be orthogonal to each other. Specifically, a locking pin 541a having a screw hole protrudes from the upper part of the back surface of the side cover 541. In addition, a mounting base 541b having a screw hole projects from a lower portion of the back surface of the side cover 541. The locking pin 541a and the mounting base 541b are disposed in the vicinity of the side edge of the side cover 541 to which the front cover 542 is attached.

  On the other hand, on the upper part of the back surface of the front cover 542, a locking hook portion 542a that can be hooked and locked to the locking pin 541a is protruded corresponding to the locking pin 541a. Further, an attachment piece 542b having a screw hole is projected from the lower portion of the back surface of the front cover 542 corresponding to the attachment base 541b. The locking hook portion 542a and the attachment piece 542b are disposed in the vicinity of the side edge attached to the side cover 541 in the front cover 542.

  In order to assemble the side cover 541 and the front cover 542 together, the locking hook portion 542a of the front cover 542 is locked to the locking pin 541a of the side cover 541 and the front cover 542 is attached. The screw hole of the piece 542b is matched with the screw hole of the mounting base 541b of the side cover 541. In the front cover 542, a plurality of fitting grooves 542c for fitting the side edges of the side cover 541 are formed on the side edge to which the side cover 541 is attached. By fitting into the fitting groove 542c, the side cover 541 and the front cover 542 are positioned. Thereafter, the locking hook portion 542a is fixed to the locking pin 541a by the fixing screw 54b, and the side cover 541 and the front cover are fixed by fixing the mounting piece 542b to the mounting base 541b by the fixing screw 54c. 542 are assembled together.

  The lower cover 54 is attached to the side frame member 451 of the toilet bowl cleaning tank 4 as shown in FIG. 3 in a state where the side cover 541 and the front cover 542 are integrally assembled as described above. As shown in FIG. 12, a pair of screw holes 541c is formed in the vicinity of the upper end of the back surface of the side cover 541, and one boss portion 541d projects between the pair of screw holes 541c. ing. The pair of screw holes 541c correspond to the pair of screw holes 451b formed in the lower end portion 451a of the side surface frame member 451 shown in FIG. 5, and the boss portion 541d is 1 formed in the lower end portion 451a of the side surface frame member 451. This corresponds to the two boss holes 451c. Therefore, the lower cover 54 is positioned by fitting the boss portion 541d into the boss hole 451c of the side surface frame member 451, and as shown in FIG. 3, the fixing screws inserted through the screw holes 541c of the side cover 541, respectively. It is fixed by 54a. By fixing the lower cover 54 with a screw, even when a load is applied to the lower cover 54, the state of attachment to the toilet bowl washing tank 4 can be maintained for a long time.

  By attaching the lower cover 54 to the toilet bowl washing tank 4 in this way, the lower space S of the toilet bowl washing tank 4 is covered. Thus, the side cover 541 of the lower cover 54 constitutes a side surface extending downward from the rear cover 52, and the front cover 542 constitutes a front surface extending downward from the front cover 51. For this reason, the rear side of the toilet bowl 2 becomes a box shape unified over the vertical direction, and the design of the toilet bowl device 1 is improved.

  When the lower cover 54 is attached to the toilet bowl cleaning tank 4, the front cover 542 is disposed so as to enter the inner side in the width direction with respect to the side covers 211 respectively attached to both side surfaces of the toilet body 21. At this time, the front cover 542 and the toilet body 21 are spaced apart from each other. The lower cover 54 is not in contact with the floor surface f1 and is disposed with a predetermined gap between the lower cover 54 and the floor surface f1.
