Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
As shown in FIG. 1, the toilet bowl device 1 shown in the present embodiment shows a floor-standing type toilet bowl device in which the toilet bowl 2 is installed on the floor surface f1. The toilet bowl device 1 includes a toilet bowl 2 and a toilet bowl cleaning device 3. In the following description, the front-back direction when viewed from the user sitting on the toilet bowl 2 is referred to as the front-back direction. Further, the left-right direction when viewed from the user sitting on the toilet bowl 2 is the width direction. Further, the vertical direction along the vertical direction with respect to the floor surface on which the toilet bowl 2 is installed is defined as the vertical direction.

The toilet bowl 2 is installed on the floor surface f1 close to the vertical wall surface f2. The toilet bowl 2 has a toilet seat 22 and a toilet lid 23 rotatably attached to the upper part of the toilet bowl main body 21, and a functional unit 24 of the toilet seat device arranged behind the toilet seat 22 and the toilet lid 23.

The tank body 41 is made of a blow molded product. The blow-molded upper surface opening 411 (see FIG. 2) of the tank body 41 is formed by cutting the upper portion of the blow-molded product in a substantially horizontal direction. Therefore, the blow-molded product can be molded by releasing the mold in the front-rear direction, and it is not necessary to provide a draft for removing the mold in the vertical direction unlike the injection-molded product. As a result, the outer peripheral surface of the tank body 41 becomes a straight surface along the vertical direction, and a side wall surface extending perpendicular to the floor surface can be formed. Therefore, the tank body 41 has a small decrease in tank volume due to the draft, and even if the depth dimension is reduced to make it thinner, it is possible to secure a larger tank volume than the injection molded product. As a result, the toilet device 1 provided with the toilet cleaning tank 4 having the tank body 41 can reduce the dimensions in the front-rear direction (the above-mentioned dimensions).

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

The inner lid 42 is provided so as to cover the upper surface opening 411 of the tank main 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 mounted along the entire circumference of the upper surface opening 411 and is screwed to the tank main body 41. On the other hand, the inspection lid 422 is not screwed to the tank main body 41, but is detachably attached to the inner lid main 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 harder than the tank body 41 and has a planar shape substantially equal to the bottom surface 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. 4) protruding from the bottom of the base plate 43. It has a function of fixing the main body 41 to the toilet bowl main body 21.

The mounting 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 the valve seat of the flapper valve 4d (not shown in FIG. 5), which is one of the internal components of the tank body 41, and is a flange portion 461 having a diameter larger than that of the lower surface opening 413. have. The valve seat 46 is mounted from the inside of the tank body 41 with the packing 46a sandwiched between the flange portion 461 and the tank body 41.

The valve seat 46 integrally has a cylindrical portion 462 having a male screw on the outer peripheral surface below the flange portion 461, and the cylindrical portion 462 projects 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 into 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 seat 46 protruding from the lower surface of the tank body 41 is inserted into the opening 432. Then, the tightening nut 46c is screwed into the cylindrical portion 462 protruding downward from the opening 432, so that the base plate 43 is sandwiched between the tightening nut 46c and the tank body 41. As a result, 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 projecting from the lower surface into a tank mounting hole (not shown) provided in the toilet body 21. As a result, 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 the washing water inflow port (not shown) of the toilet body 21 so that the washing water in the tank body 41 can be supplied to the toilet body 21.

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

Since the dew-proof material 44 is divided into two in the front-rear direction by the front-side dew-proof material 441 and the rear-side dew-proof material 442, a draft for removing from the mold is provided in the front-rear direction, and the dew-proof material 44 is provided in the vertical direction. Is not provided with a draft. As a result, the dew-proof material 44 formed by combining the front-side dew-proof material 441 and the rear-side 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 cleaning tank 4. Can be formed. As a result, even if the toilet bowl cleaning tank 4 is made thinner, there is no possibility that the tank volume of the toilet bowl cleaning tank 4 will be reduced due to the draft of the dew-proof material. Moreover, in combination with the fact that the tank body 41 shown in the present embodiment is not provided with a draft in the vertical direction, it is possible to further reduce the thickness of the toilet bowl cleaning tank 4, and the front and rear of the toilet bowl device 1 can be further reduced. It is possible to further reduce the dimension in the direction (the above-mentioned dimension).

As shown in FIG. 4, the reinforcing frame 45 shown in the present embodiment extends in the width direction toward the front side of the toilet bowl cleaning tank 4 and the metal side frame members 451 arranged on both side surfaces of the toilet bowl cleaning tank 4. It has a metal reinforcing stay 452, which is arranged in the. In FIG. 4, the toilet bowl main body 21 is shown by a broken line, and the toilet seat 22, the toilet lid 23, the functional portion 24 of the toilet bowl device, and the tank cover 5 on the toilet bowl main body 21 are not shown.

The side frame members 451 are fixed to both end faces 43a (see FIG. 4) in the width direction of the base plate 43 by fixing screws 45a, respectively. The side frame member 451 is arranged so as to cover the side surface of the toilet bowl cleaning tank 4 in a range extending from the base plate 43 to a height of approximately ½ of the tank body 41. The side frame member 451 is formed in a U-shape in a plan view, and by being attached to the base plate 43, the dew-proof material 44 is prevented from opening back and forth between the front dew-proof material 441 and the rear dew-proof material 442. Is sandwiched from the front and back.

Both ends of the reinforcing stay 452 are fixed to the left and right side frame members 451 by fixing screws 45b, respectively. As a result, the left and right side frame members 451 are connected to each other by the reinforcing stay 452, and the side frame member 451 is prevented from spreading in the left-right direction due to the springback or the like generated in the side frame member 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. The load acting on the reinforcing stay 452 is transmitted to each side frame member 451 from both ends of the reinforcing stay 452. Since the side frame member 451 is 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.

Since the dew-proof material 44 divided in the front-rear direction is also provided with a draft in the front-rear direction, as shown in FIG. 4, the reinforcing stay 452 of the reinforcing frame 45 is housed in the front surface of the front dew-proof material 441. It can have a recess 44a to be formed and a recess 44b for accommodating the side frame member 451. Since the recesses 44a and 44b can suppress the amount of protrusion of the reinforcing frame 45 to the front, the toilet bowl cleaning tank 4 is made thinner without reducing the tank volume of the tank body 41 even if the reinforcing frame 45 is provided. can do.

As shown in FIGS. 1 to 3, the tank cover 5 includes a front cover 51 that covers the front of the toilet bowl cleaning tank 4, a rear cover 52 that covers the sides and the rear of the toilet bowl cleaning tank 4, and an upper part of the toilet bowl cleaning tank 4. It has an upper cover 53 and a cover. The front cover 51 is arranged above the toilet bowl main body 21 and is arranged between the functional portion 24 of the toilet seat device on the toilet bowl main body 21 and the toilet bowl cleaning tank 4. As shown in FIG. 2, the front cover 51 is formed longer than the toilet bowl 2 (including the toilet seat 22, the toilet lid 23, and the functional portion 24) in the width direction.

The rear cover 52 has a height substantially the same as the height of the toilet bowl cleaning tank 4. The rear cover 52 is screwed to the side frame members 451 provided on both sides of the toilet bowl cleaning tank 4 by fixing screws 52a. As a result, the tank cover 5 shown in the present embodiment is indirectly fixed to the toilet bowl main body 21 via the side frame member 451 and the base plate 43. Further, the front cover 51 and the upper cover 53 are divided with respect to the rear cover 52, and are provided so as to be removable with respect to the rear cover 52. As a result, the entire toilet bowl cleaning tank 4 is shielded by the tank cover 5, the appearance is improved, and the design is improved.

The lower part of the toilet bowl cleaning tank 4 and the rear part of the toilet bowl 2 are covered with a lower cover 54. As a result, the piping parts (not shown) and the like arranged behind the toilet bowl 2 are blindfolded, and the rear side of the toilet bowl 2 is unified into a thin, substantially rectangular shape extending downward from the toilet bowl cleaning device 3. The sex is further improved.

As shown in FIGS. 2 and 9, the front cover 51 of the tank cover 5 is arranged so as to be vertical when the toilet device 1 is viewed from the side. Further, as shown in FIG. 2, the rear surface 241 of the functional portion 24 of the toilet seat device provided in the toilet bowl main body 21 is curved in the width direction so as to be recessed toward the front. The surface of the front cover 51 is curved in the width direction along the rear surface 241 of the functional portion 24 so as to be convex toward the front. As described above, since the tank body 41 does not have a vertical draft and has a side wall surface extending perpendicular to the floor surface, the front cover 51 is brought as close as possible to the tank body 41. be able to. Moreover, since the front cover 51 is curved in the width direction so as to be convex toward the front, the tank body 41 is made larger by the amount curved forward as compared with the case where the front cover 51 is a flat surface. can do. This makes it possible to secure the tank volume of the tank body 41.

Further, since the front cover 51 is curved in the width direction toward the front, both ends of the front cover 51 in the width direction are provided on the back side of the front cover 51 as shown by the alternate long and short dash line in FIG. The space portion S is formed on the front side of the passing plane. The front surface side of the tank main body 41 and the dew-proof material 44 is arranged in the space portion S in the vertical direction. Therefore, the tank main body 41 can be brought as close as possible to the front cover 51 side, and a large tank volume can be secured by that amount.

Further, since the front cover 51 is perpendicular to the side view, when the toilet seat 22 and the toilet lid 23 are rotated upward, it becomes difficult to come into contact with the front cover 51, and the tank cover 5 and the toilet seat 22 and the toilet lid 23 come into contact with each other. The distance can be as close as possible.

Since the front cover 51 of the tank cover 5 is divided with respect to the rear cover 52 and is removable, it is easy to remove the front cover 51 to the toilet bowl cleaning tank 4 during maintenance of the toilet bowl cleaning tank 4. Is accessible to. At this time, since it is not necessary to remove the toilet bowl cleaning tank 4 itself from the toilet bowl main body 21, maintenance work can be easily performed.

The front cover 51 shown in the present embodiment may be attached and detachably attached from the front of the rear cover 52, but is preferably removable upward with respect to the rear cover 52. As a result, the front cover 51 is removed with respect to the toilet bowl cleaning tank 4 while the toilet seat 22, the toilet lid 23, and the functional portion 24 of the toilet seat device, which are arranged in front of the lower part of the tank cover 5, are attached to the toilet bowl main body 21. It becomes possible to access, and the maintainability of the toilet bowl cleaning tank 4 can be further improved.

Here, the mounting structure of 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. 6 to 8.
First, as shown in FIG. 6, the front ridges 522 and the rear ridges along the vertical direction are outside the two front ends 521 of the rear cover 52 (only one front end 521 is shown in FIG. 6). 523 is provided. The front ridge 522 and the rear ridge 523 are parallel. Of these, the rear ridges 523 are formed over substantially the entire length of the rear cover 52 in the vertical direction, whereas the front ridges 522 are spaced at regular intervals in the vertical direction of the rear cover 52. It is 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 in the portion where the front ridge portion 522 is provided on the outside of the front end portion of the rear cover 52. ..

On the other hand, as shown in FIG. 2, the front cover 51 has an overhang shape that projects to both sides of the rear cover 52 by being formed slightly wider than the rear cover 52. As a result, when the toilet device 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, 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 project slightly upward from the rear cover 52, and also covers the height direction of the rear cover 52. Therefore, since the entire rear cover 52 is covered by the back surface of the front cover 51, the design of the toilet bowl device 1 is further improved.

As shown in FIG. 7, the front cover 51 is formed with outer peripheral ribs 511 from both end edges in the width direction to the upper end edges. The outer peripheral rib 511 projects rearward so as to cover the groove 524 of the front end portion 521 of the rear cover 52. Of these, a plurality of engaging protrusions 512 that can engage with the groove 524 of the rear cover 52 are formed inside the outer peripheral ribs 511a arranged at both ends in the width direction of the front cover 51 at intervals in the vertical direction. ing. The length of one engaging protrusion 512 in the vertical direction is formed to be slightly shorter than the distance between the front ridge portions 522 adjacent to the upper and lower sides of the rear cover 52.

When the front cover 51 is attached to the rear cover 52, the engaging projection 512 is brought into contact with the rear ridge 523 through between the front ridges 522 adjacent to the top and bottom, and then the rear ridge 523 is brought into contact with the rear ridge 523. By sliding downward along 523, the engaging projection 512 of the front cover 51 engages the groove 524 between the front ridge 522 and the rear ridge 523, as shown in FIG. Let me. As a result, the front cover 51 is attached so as to be slidable upward with respect to the rear cover 52. Since the front cover 51 can be attached and detached by passing the engaging projection 512 of the front cover 51 between the vertically adjacent front protrusions 522, the front cover 51 can be attached and detached. The movement stroke can be shortened.

Since the engaging protrusion 512 of the front cover 51 is provided inside the outer peripheral rib 511a, sink marks due to the provision of the engaging protrusion 512 are not formed on the front surface of the front cover 51, and the appearance of the front cover 51 is not formed. Will also be good. Further, since the outer peripheral rib 511a of the front cover 51 can cover the engaging portion between the front cover 51 and the rear cover 21, the appearance of the toilet device 1 from the side is also good.

The front cover 51 attached to the rear cover 52 is attached above the rear cover 52 by utilizing 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 mounting portion 525 is provided at a portion above the toilet bowl cleaning tank 4 at the upper end portion of the front end portion 521 of the rear cover 52. The front cover 51 abuts the mounting piece 513 against the front cover mounting portion 525 of the rear cover 52 and is fixed by the fixing screw 51a. Therefore, the front cover 51 can be removed by removing the fixing screw 51a above the toilet bowl cleaning tank 4 while the toilet bowl cleaning tank 4 is fixed to the toilet bowl main body 21. As a result, the front cover 51 can be easily replaced or the design can be replaced.

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

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 FIGS. 10 and 11, a protrusion 531 projecting upward is provided at the center of the front end of the upper cover 53. On the other hand, as shown in FIGS. 7 and 9, the inner end side of the outer peripheral rib 511b is further bent downward at the central portion of the outer peripheral rib 511b on the upper end side of the front cover 51, so that the upper cover 53 is further bent. A storage groove 515 for accommodating the protrusion 531 is formed.

The upper cover 53 is mounted on the upper part of the rear cover 52 by accommodating the protrusion 531 in the accommodating groove 515 of the front cover 51. After that, the upper cover 53 is fixed to the screw hole 526 provided at the upper end of the front end portion 521 of the rear cover 52 by the fixing screw 53a. As a result, the upper end portion of the front cover 51 engages with the upper cover 53, so that the front cover 51 is prevented from coming off forward. 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 with the back surface, it is difficult to see the upper cover 53 from the front side of the toilet bowl device 1.

In the tank cover 5 configured as described above, when removing the front cover 51, as shown in FIG. 10, first, the upper cover 53 is removed from the upper part of the rear cover 52, and then the fixing screw 51a of the front cover 51 is used.
