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 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 is divided into two so that the front dew-proof material 441 and the rear dew-proof material 442 do not open back and forth by being attached to the base plate 43. The dew-proof material 44 is sandwiched from the front-rear direction.

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.

As shown in FIGS. 3 and 4, each side frame member 451 is provided with an adjuster 453 that projects rearward. The adjuster 453 is attached so that the amount of protrusion can be adjusted, and as shown in FIG. 6, the adjuster 453 protrudes rearward from the opening 521 formed in the rear surface 520 of the rear cover 52. As shown in FIG. 2, the adjuster 453 keeps the distance between the standing wall surface f2 and the toilet bowl cleaning tank 4 constant by abutting against the standing wall surface f2, and the toilet bowl cleaning tank 4 is excessively tilted to the rear side. To prevent.

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. 3, 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.
