[0008] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. The toilet apparatus 1 shown in this embodiment is a floor-standing toilet apparatus in which a toilet bowl 2 is installed on a floor surface f1, as shown in Figure 1. The toilet apparatus 1 comprises a toilet bowl 2 and a toilet flushing apparatus 3. In the following description, the front-to-back direction is the direction from the front to the back as seen by a user seated on the toilet bowl 2. The left-to-right direction is the direction from the front to the back as seen by a user seated on the toilet bowl 2. The width direction is the direction from the top to the bottom as seen by a user seated on the toilet bowl 2. Furthermore, the up-down direction is the direction perpendicular to the floor surface on which the toilet bowl 2 is installed.
[0009] The toilet 2 is installed on a floor surface f1 close to a vertical wall surface f2. The toilet 2 has a toilet seat 22 and a toilet lid 23 rotatably attached to the top of a toilet body 21, and a functional part 24 of the toilet seat device located behind the toilet seat 22 and the toilet lid 23. The toilet body 21 shown in this embodiment is made of pottery, a fired product. Side covers 211 are detachably attached to both sides of the rear of the toilet body 21 using hook-and-loop fasteners or the like, and cover the rear of the toilet body 21.
[0010] The toilet flushing device 3 is disposed behind the toilet body 21. The toilet flushing device 3 comprises a toilet flushing tank 4 and a tank cover 5 which is the exterior body of the toilet flushing tank 4. As shown in FIG. 3, the toilet flushing tank 4 includes a tank body 41, an inner lid 42, a base plate 43, a moisture-proof material 44, and a reinforcing frame 45.
[0011] The tank body 41 is made of a blow-molded product. The top opening 411 (see FIG. 2) of the blow-molded tank body 41 is formed by cutting the upper part of the blow-molded product in a substantially horizontal direction. Therefore, blow-molded products can be molded by demolding in the front-to-rear direction, eliminating the need for a vertical draft angle for demolding, as is the case with injection-molded products. As a result, the outer peripheral surface of the tank body 41 is a straight surface along the vertical direction, allowing for the formation of sidewall surfaces that extend perpendicular to the floor. Therefore, the tank body 41 is less subject to a reduction in tank volume due to the draft angle, and even when the tank body 41 is made thinner by reducing its depth, it can still maintain a larger tank volume than an injection-molded product. As a result, a toilet apparatus 1 equipped with a toilet flushing tank 4 having this tank body 41 can be made smaller in front-to-rear dimension (the aforementioned dimension).
[0012] Flush water is stored inside the tank body 41, and as shown in Figure 2, internal parts for flushing the toilet are housed inside. Specifically, the tank body 41 houses a ball tap 4a that supplies water, a float 4b that stops the water from flowing from the ball tap 4a, an overflow pipe 4c that limits the flush water level and supplies makeup water to the toilet body 21, a flapper valve 4d that opens and closes the drain outlet, a ball chain 4e that pulls up the flapper valve 4d, and a lifting arm 4f that pulls up the ball chain 4e. A spindle 4h of a lever handle 4g that is attached to the outside of the tank cover 5 is connected to the lifting arm 4f.
[0013] The inner lid 42 is provided to cover the top opening 411 of the tank body 41. The inner lid 42 is composed of an inner lid main body 421 and an inspection lid 422. The inner lid main body 421 is attached along the entire circumference of the top 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, but is detachably attached to the inner lid main body 421. Therefore, by removing the inspection lid 422 from the inner lid main body 421, the interior of the tank body 41 can be accessed without removing the inner lid main body 421 to which it is screwed.
[0014] The base plate 43 is attached to the bottom of the tank body 41. The base plate 43 shown in this embodiment is formed from a resin that is harder than the tank body 41, and has a planar shape that is approximately the same as the shape of the bottom surface of the tank body 41. The base plate 43 supports the underside of the tank body 41, and also has the function of fixing the tank body 41 to the toilet body 21 by being fixed to the upper surface 21a of the rear side of the toilet body 21 by a pair of tightening bolts 431 (see FIG. 3) that protrude from the bottom of the base plate 43.
[0015] The attachment structure between the tank body 41 and the base plate 43 is shown in Figure 4. A circular lower opening 413 is formed in the bottom surface 412 of the tank body 41. A substantially cylindrical valve seat 46 is attached to this lower opening 413. The valve seat 46 is a component that constitutes the valve seat of a flapper valve 4d (not shown in Figure 4), which 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 opening 413. The valve seat 46 is attached from the inside of the tank body 41, with a packing 46a sandwiched between the flange portion 461 and the tank body 41.
[0016] The valve seat 46 has a cylindrical portion 462 integrally formed therewith below the flange portion 461 and having a male thread on its outer circumferential surface, and this cylindrical portion 462 protrudes downward from the bottom opening 413. The valve seat 46 is attached to the tank body 41 by threading a tightening nut 46b from the outside of the tank body 41 onto the cylindrical portion 462 protruding from the bottom opening 413.
[0017] Meanwhile, a circular opening 432 is provided in the center of the base plate 43, and a cylindrical portion 462 of the valve seat 46 protruding from the underside of the tank body 41 is inserted into this opening 432. A clamping nut 46c is screwed onto the cylindrical portion 462 protruding downward from this opening 432, thereby sandwiching the base plate 43 between the clamping nut 46c and the tank body 41. In this way, the base plate 43 is fixed to the bottom of the tank body 41.
[0018] The base plate 43 fixed to the tank body 41 is fixed by inserting a pair of tightening bolts 431 protruding from the underside into tank mounting holes (not shown) provided in the toilet body 21. In this way, the tank body 41 is fixed to the toilet body 21 via the base plate 43. The cylindrical portion 462 of the tank body 41 fixed to the toilet body 21 communicates with a flush water inlet (not shown) of the toilet body 21, making it possible to supply flush water from within the tank body 41 to the toilet body 21.
[0019] The dew prevention material 44 is made of polystyrene foam resin or the like and is molded into a shape that conforms to the outer circumferential surface of the tank body 41. The dew prevention material 44 shown in this embodiment is divided into two parts, a front dew prevention material 441 and a rear dew prevention material 442, which are attached to the outer circumferential surface of the tank body 41 so as to sandwich the tank body 41 from the front and rear directions. The dew prevention material 44 has a height that corresponds to at least the water level of the flushing water stored in the tank body 41.
[0020] Because this dew-proofing material 44 is divided into two in the front-to-back direction, a front dew-proofing material 441 and a rear dew-proofing material 442, a draft angle is provided in the front-to-back direction to facilitate release from the molding die, but no draft angle is provided in the up-to-down direction. As a result, the dew-proofing material 44, which is formed by combining the front dew-proofing material 441 and the rear dew-proofing material 442, can form surfaces that extend vertically in the up-to-down direction on the front and rear sides of the toilet flushing tank 4. As a result, even if the toilet flushing tank 4 is made thinner, there is no risk of a reduction in the tank volume of the toilet flushing tank 4 due to the draft angle of the dew-proofing material. Moreover, this, combined with the fact that the tank body 41 shown in this embodiment also does not have a draft angle in the up-to-down direction, makes it possible to further reduce the thickness of the toilet flushing tank 4, and further reduce the front-to-back dimension (front dimension) of the toilet device 1.
[0021] As shown in Figure 3, the reinforcing frame 45 shown in this embodiment has metal side frame members 451 arranged on both side surfaces of the toilet flushing tank 4, and metal reinforcing stays 452 arranged to extend in the width direction on the front side of the toilet flushing tank 4. Note that in Figure 3, the toilet body 21 is shown by a dashed line, and the toilet seat 22, toilet lid 23, and functional part 24 of the toilet device on the toilet body 21 are not shown.
[0022] The side frame member 451 corresponds to the support member of the present invention. The side frame member 451 is fixed to both widthwise end faces 43a (see FIG. 3) of the base plate 43 with fixing screws 45a. As a result, the side frame member 451 is indirectly attached to the toilet body 21 via the base plate 43 of the toilet flushing tank 4. The side frame member 451 is arranged to cover the side of the toilet flushing tank 4 in an area 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 by being attached to the base plate 43, it sandwiches the two-piece dew-proof material 44 from the front to the back so that the front dew-proof material 441 and the rear dew-proof material 442 do not separate in the front to back direction. This side frame member 451 corresponds to the frame member of the present invention.
[0023] 5, a lower end 451a of the side frame member 451 is not covered by the rear cover 52 and protrudes downward below the rear cover 52 and the base plate 43. This lower end 451a serves as an attachment portion for the lower cover 54, which will be described later. Two screw holes 451b and one boss hole 451c are formed therein.
[0024] Both ends of the reinforcing stay 452 are fixed to the left and right side frame members 451 with fixing screws 45b, respectively. This connects the left and right side frame members 451 with the reinforcing stay 452, preventing the side frame members 451 from spreading in the left-right direction due to springback or the like that occurs in the side frame members 451.
[0025] The reinforcing frame 45 functions to receive the load when a user leans on the tank cover 5 and prevent the load from acting directly on the tank body 41. The load acting on the reinforcing stay 452 is transmitted from both ends of the reinforcing stay 452 to each side frame member 451. Because the side frame members 451 are fixed to the base plate 43, which is more robust than the tank body 41, the load transmitted from the reinforcing stay 452 can be effectively received and released to the toilet body 21 via the base plate 43.
[0026] 1 to 3, the tank cover 5 has a front cover 51 that covers the front of the toilet flushing tank 4, a rear cover 52 that covers the sides and rear of the toilet flushing tank 4, and an upper cover 53 that covers the top of the toilet flushing tank 4. The front cover 51 is positioned above the toilet body 21, and is positioned between the toilet flushing tank 4 and the functional part 24 of the toilet seat device on the toilet body 21.
[0027] The rear cover 52 has approximately the same height as the toilet flushing tank 4. The rear cover 52 is secured to side frame members 451 provided on both sides of the toilet flushing tank 4 with fixing screws 52a. The front cover 51 and upper cover 53 are detachably provided on the rear cover 52. As a result, the tank cover 5 shown in this embodiment is indirectly secured to the toilet body 21 via the side frame members 451 and the base plate 43. Furthermore, because the entire toilet flushing tank 4 is shielded by the tank cover 5, the appearance is improved and the design is enhanced.
[0028] Furthermore, the space S below the toilet flushing tank 4 is covered by the lower cover 54, which conceals the piping component 100 (see FIG. 3) located behind the toilet 2 and unifies the rear side of the toilet 2 into a thin, approximately rectangular shape extending downward from the toilet flushing device 3, further improving the design. Details of this lower cover 54 will be described later.
[0029] The front cover 51 of the tank cover 5 is removable from the rear cover 52, so when performing maintenance on the toilet flush tank 4, the toilet flush tank 4 can be easily accessed by removing the front cover 51. At this time, there is no need to remove the toilet flush tank 4 itself from the toilet body 21, so maintenance work can be performed easily.
[0030] The front cover 51 shown in this embodiment is provided so that it can be removed upward from the rear cover 52. This makes it possible to remove the front cover 51 and access the toilet flush tank 4 while the toilet seat 22, toilet lid 23, and functional part 24 of the toilet seat device, which are located in front of the lower part of the tank cover 5, remain attached to the toilet body 21, further improving the maintainability of the toilet flush tank 4.
[0031] Here, the engagement structure between the front cover 51 and the rear cover 52 of the tank cover 5 shown in this embodiment will be described with reference to FIGS. First, as shown in Fig. 6, a front protrusion 522 and a rear protrusion 523 are provided on the outer sides of two front end portions 521 of the rear cover 52 (only one of the front end portions 521 is shown in Fig. 6) along the up-down direction. The front protrusion 522 and the rear protrusion 523 are parallel to each other. Of these, the rear protrusion 523 is formed over substantially the entire length of the rear cover 52 in the up-down direction, whereas the front protrusion 522 is divided into multiple portions spaced at regular intervals in the up-down direction of the rear cover 52. As a result, a groove 524 is formed between the front protrusion 522 and the rear protrusion 523 only in the area where the front protrusion 522 is provided on the outer side of the front end portion 521 of the rear cover 52.
[0032] On the other hand, as shown in Figure 7, the front cover 51 is formed slightly wider than the rear cover 52, and thus has an overhanging shape that protrudes on both sides of the rear cover 52. As a result, when the toilet apparatus 1 is viewed from the front (observed from the front side), the rear cover 52 is covered by the front cover 51 and does not protrude from both sides of the front cover 51, resulting in a good appearance. Moreover, as shown in Figure 1, the upper part of the front cover 51 is also formed to protrude slightly upward more than the rear cover 52, and also covers the rear cover 52 in the height direction. Therefore, the rear cover 52 is entirely covered by the back surface of the front cover 51, further improving the design of the toilet apparatus 1.
[0033] 7, the front cover 51 is formed with peripheral ribs 511 extending from both widthwise edges to the upper edge. The peripheral ribs 511 protrude rearward so as to cover the grooves 524 in the front end portion 521 of the rear cover 52. Among these, a plurality of engagement protrusions 512 capable of engaging with the grooves 524 of the rear cover 52 are formed at intervals in the vertical direction on the inner side of the peripheral ribs 511a arranged at both widthwise edges of the front cover 51. The vertical length of one engagement protrusion 512 is formed slightly shorter than the distance between the front protrusions 522 adjacent to each other above and below the rear cover 52.
[0034] When attaching this front cover 51 to the rear cover 52, the engaging protrusions 512 are passed between the vertically adjacent front protrusions 522 to abut against the rear protrusions 523, and then slid downward along the rear protrusions 523, thereby engaging the engaging protrusions 512 of the front cover 51 with the grooves 524 between the front protrusions 522 and the rear protrusions 523, as shown in FIG. 8 . This allows the front cover 51 to be attached so as to be slidably movable upward relative to the rear cover 52. The front cover 51 can be attached and detached by passing the engaging protrusions 512 of the front cover 51 between the vertically adjacent front protrusions 522, thereby shortening the movement stroke for attaching and detaching the front cover 51.
[0035] Because the engagement protrusions 512 of the front cover 51 are provided inside the outer peripheral ribs 511a, sink marks caused by providing the engagement protrusions 512 are not formed on the front surface of the front cover 51, improving the appearance of the front cover 51. Furthermore, because the outer peripheral ribs 511a of the front cover 51 can cover and conceal the engagement portion between the front cover 51 and the rear cover 52, the toilet apparatus 1 also looks good from the side.
[0036] 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, front cover attachment parts 525 are provided on the upper end of the front end part 521 of the rear cover 52 at a position above the toilet flush tank 4. The front cover 51 is fixed by abutting the attachment pieces 513 against the front cover attachment parts 525 of the rear cover 52. For this reason, while the toilet flush tank 4 remains fixed to the toilet body 21, the front cover 51 can be removed by removing the attachment screws 51a above the toilet flush tank 4. This makes it easy to replace or redesign the front cover 51.
[0037] Furthermore, since the front cover 51 is separate from the rear cover 52, it is possible to make the colors of the front cover 51 and the rear cover 52 different. For example, by making the rear cover 52 a darker color than the front cover 51 to create a difference in brightness, the front cover 51 can be given a floating feel, further improving the design. Furthermore, the front cover 51 and the rear cover 52 can be made of different materials.
[0038] The upper cover 53 is attached to the upper part of the rear cover 52 after the front cover 51 is fixed to the rear cover 52. As shown in Figures 10 and 11, the upper cover 53 has a protrusion 531 that protrudes upward at the center of the front end. Meanwhile, at the center of the outer peripheral rib 511b on the upper end side of the front cover 51, as shown in Figures 7 and 9, the inner end side of the outer peripheral rib 511b is further bent downward to form an accommodation groove 515 that accommodates the protrusion 531 of the upper cover 53.
[0039] The upper cover 53 is attached to the top of the rear cover 52 by fitting the protrusions 531 into the fitting grooves 515 of the front cover 51. The upper cover 53 is then fixed by fixing screws 53a into threaded holes 526 provided at the upper end of the front end portion 521 of the rear cover 52. This engages the upper end portion of the front cover 51 with the upper cover 53, preventing the front cover 51 from slipping off forward. The upper surface of the upper cover 53 is inclined downward toward the rear, as shown in Figures 10 and 11. The upper end portion of the front cover 51 extends so as to cover the upper cover 53 behind it, making it difficult to see the upper cover 53 from the front side of the toilet apparatus 1.
[0040] When removing the front cover 51 of the tank cover 5 configured in this manner, as shown in Figure 10, first remove the upper cover 53 from above the rear cover 52, and then remove the fixing screws 51a of the front cover 51. Then, by sliding the front cover 51 upward, the front side of the toilet flushing tank 4 is opened, allowing maintenance to be performed.
[0041] Next, the lower cover 54 will be described. The lower covers 54 shown in this embodiment are provided in pairs on the toilet apparatus 1. That is, as shown in Figure 3, the lower covers 54 are disposed below the toilet flushing tank 4 and on the left and right rear sides of the toilet body 21.
[0042] The pair of lower covers 54 have substantially the same configuration, so the specific configuration of one of the lower covers 54 (the lower cover 54 disposed on the left side of the toilet apparatus 1 as seen from the user) will be described with reference to FIG. The lower cover 54 shown in this embodiment is composed of a side cover 541 and a front cover 542. The side cover 541 is a plate material that covers the sides of the space S below the toilet flushing tank 4, and the front cover 542 is a plate material that covers the front of the space S below the toilet flushing tank 4.
[0043] The side cover 541 and the front cover 542 are combined together so that they are perpendicular to each other. Specifically, a locking pin 541a having a threaded hole protrudes from the upper part of the back surface of the side cover 541. Furthermore, a mounting base 541b having a threaded hole protrudes from the lower part of the back surface of the side cover 541. The locking pin 541a and the mounting base 541b are arranged near the side edge of the side cover 541 to which the front cover 542 is attached.
[0044] Meanwhile, locking hook portions 542a that can be hooked onto and locked onto locking pins 541a are protruding from the upper part of the rear surface of front cover 542. Furthermore, mounting pieces 542b that have screw holes and that correspond to mounting bases 541b are protruding from the lower part of the rear surface of front cover 542. Locking hook portions 542a and mounting pieces 542b are located near the side edges of front cover 542 that are attached to side covers 541.
[0045] To assemble the side cover 541 and the front cover 542 together, the locking hook portions 542a of the front cover 542 are locked onto the locking pins 541a of the side cover 541, and the screw holes of the mounting pieces 542b of the front cover 542 are aligned with the screw holes of the mounting bases 541b of the side cover 541. The front cover 542 has a plurality of fitting grooves 542c formed on its side edges to which the side cover 541 is attached, into which the side edges of the side cover 541 are fitted, and the side covers 541 and the front cover 542 are positioned by fitting the side edges of the side cover 541 into the fitting grooves 542c. Thereafter, the locking hook portion 542a is fixed to the locking pin 541a with the fixing screw 54b, and the mounting piece 542b is fixed to the mounting base 541b with the fixing screw 54c, thereby assembling the side cover 541 and the front cover 542 together.
[0046] With the side covers 541 and the front cover 542 assembled together in this manner, the lower cover 54 is attached to the side frame member 451 of the toilet flushing tank 4, as shown in FIG. 3. A pair of screw holes 541c are formed near the upper end of the back surface of the side cover 541, as shown in FIG. 12, and a boss portion 541d protrudes between the pair of screw holes 541c. The pair of screw holes 541c correspond to the pair of screw holes 451b formed in the lower end 451a of the side frame member 451 shown in FIG. 5, and the boss portion 541d corresponds to the boss hole 451c formed in the lower end 451a of the side frame member 451. Therefore, the lower cover 54 is positioned by fitting the boss portions 541d into the boss holes 451c of the side frame member 451, and is fixed by fixing screws 54a that are inserted into the screw holes 541c of the side cover 541, as shown in FIG. 3. By being fixed with screws, the lower cover 54 can maintain its attached state to the toilet flushing tank 4 for a long period of time even when a load is applied to the lower cover 54.
[0047] By attaching the lower cover 54 to the toilet flushing tank 4 in this way, the space S below the toilet flushing tank 4 is covered and concealed. As a result, the side covers 541 of the lower cover 54 form the side faces extending downward from the rear cover 52, and the front cover 542 forms the front face extending downward from the front cover 51. As a result, the rear side of the toilet 2 has a uniform box-like shape in the vertical direction, improving the design of the toilet device 1.
[0048] When the lower cover 54 is attached to the toilet flushing tank 4, the front cover 542 is positioned so that it is positioned widthwise inward relative to the side covers 211 attached to both side surfaces of the toilet body 21. At this time, there is a gap between the front cover 542 and the toilet body 21. The lower cover 54 is also not in contact with the floor surface f1, and is positioned with a predetermined gap between it and the floor surface f1. These gaps allow dimensional errors in the width and height of the toilet body 21 to be absorbed, so the lower cover 54 will not come into contact with the toilet body 21 or the floor surface f1 and become displaced due to dimensional errors in the toilet body 21. The front cover 542 of the lower cover 54 is also positioned with a gap between it and the side cover 211. This allows the attachment of the side cover 211 to be adjusted.
[0049] Furthermore, the lower cover 54 shown in this embodiment is divided into the side cover 541 and the front cover 542, and therefore the side cover 541 and the front cover 542 can be made of different colors or materials. In particular, by making the colors of the side cover 541 and the front cover 542 different, the design can be further improved.
[0050] Furthermore, because the toilet body 21 shown in this embodiment is a baked product, there is generally large individual variation and dimensional dispersion. However, because the lower cover 54 is fixed to the side frame member 451 of the toilet flushing tank 4, which is fixed to the toilet body 21, and the toilet body 21 is used as the mounting reference, it can maintain its position integral with the toilet body 21 regardless of individual variations in the toilet body 21. For this reason, even if the position of the toilet 2 is changed due to renovations, etc., the overall position of the tank cover 5, including the lower cover 54, will not shift relative to the toilet 2.
[0051] Furthermore, the lower cover 54 is not limited to being fixed by the fixing screws 54a, but may be removably attached by magnets or hook-and-loop fasteners. The fixing structure of the side cover 541 and the front cover 542 may also be such that they are integrally assembled by magnets or hook-and-loop fasteners.
[0052] In the above embodiment, the side frame member 451 is fixed to the base plate 43 of the toilet flushing tank 4, but the side frame member 451 may also be fixed directly to the toilet body 21.
[0053] Furthermore, the support members of the lower cover 54 do not have to be provided on both end surfaces 43a of the base plate 43. For example, the support members may be provided on the front surface side or rear surface side of the base plate 43. [Explanation of symbols]
