BEST MODE FOR CARRYING OUT THE INVENTION 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 type toilet device in which the toilet bowl 2 is installed on the floor f1. In the following description, the front-rear direction when viewed from the user seated on the toilet bowl 2 is defined as the front-rear direction. Moreover, let the left-right direction at the time of seeing from the user who sat down on the toilet bowl 2 be a width direction. Furthermore, the up-down direction along the vertical direction with respect to the floor surface f1 on which the toilet bowl 2 is installed is defined as the up-down direction.

The toilet device 1 includes a toilet bowl cleaning tank 4 for storing flushing water to be supplied to the toilet body 21 on an upper surface 21 a on the rear side of the toilet body 21 . The toilet bowl cleaning tank 4 has a tank capacity capable of storing 3 L (liters) or more of cleaning water. The toilet bowl cleaning tank 4 is covered with a tank cover 5. - 特許庁A front surface 50a and a rear surface 50b of the tank cover 5 are arranged perpendicular to the floor surface f1 in a side view. The position of the rear surface 50b of the tank cover 5 is the same as the position of the rearmost end of the toilet body 21 or is arranged behind the position of the rearmost end of the toilet body 21. - 特許庁

In this toilet device 1, the horizontal distance (front dimension) from the front end P1 of the toilet body 21 to the rear end P3 of the tank cover 5 is Da, and the distance from the front end P2 of the tank cover 5 to the rear end P3 of the tank cover 5 is Da. When the horizontal distance (maximum depth dimension) of is Db, the relationship Db≤Da/5 is satisfied.

In the toilet device 1 that satisfies this relationship, even when the size of the toilet bowl 21b of the toilet bowl main body 21 is the same as the size of the conventional toilet bowl, the forward dimension (horizontal distance Da) of the toilet bowl device 1 is made smaller than before. can do. For example, when the size of the toilet bowl is 460 mm, according to the toilet device 1 according to the present invention, the horizontal distance Db (maximum depth dimension of the toilet cleaning tank 4) is set to about 130 mm, so that the tank volume of 3 L can be reduced. The horizontal distance Da (the forward dimension of the toilet device 1) can be reduced to about 675 mm while ensuring this.

Thus, in order to reduce the forward dimension of the toilet device 1 without changing the size of the toilet bowl 21b of the toilet body 21, it is necessary to reduce the depth dimension of the toilet cleaning tank 4 to make it thinner. Therefore, one embodiment of the toilet device 1 having the toilet cleaning tank 4 which is made thinner will be described below with reference to FIGS. 2 to 8. FIG.

As shown in FIG. 2 , the toilet device 1 includes a toilet bowl 2 and a toilet cleaning device 3 . 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 body 21, and a toilet seat device functional part 24 arranged behind the toilet seat 22 and the toilet lid 23. there is 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 to shield the rear portion of the toilet body 21 .

The toilet bowl cleaning device 3 is arranged behind the toilet 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 .
The toilet bowl cleaning tank 4 includes a tank body 41, an inner lid 42, a base plate 43, a condensation preventive material 44, and a reinforcing frame 45, as shown in FIGS.

The tank body 41 is made of a blow-molded product. A top opening 411 (see FIG. 3) of the blow-molded 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 there is no need to provide a vertical draft angle for mold release unlike the injection-molded product. As a result, as shown in FIG. 6, the outer peripheral surface of the tank body 41 becomes a straight surface along the vertical direction, and can constitute a side wall surface extending perpendicularly to the floor surface. Therefore, the tank body 41 is less likely to decrease in tank volume due to the draft angle, and can secure a large tank volume compared to an injection-molded product even if the depth dimension is reduced and the thickness is reduced. As a result, the toilet device 1 including the toilet bowl cleaning tank 4 having the tank body 41 can be reduced in size in the front-rear direction (front dimension).

Inside the tank main body 41, flush water is stored and, as shown in FIG. 4, internal parts for flushing the toilet bowl are accommodated. Specifically, the tank main body 41 contains a ball tap 4a for supplying water, a float 4b for stopping the ball tap 4a, and an overflow for limiting the water level of flush water and supplying makeup 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 lifting the flapper valve 4d, a lifting arm 4f for lifting 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 lifting arm 4f.

The inner lid 42 is provided so as to cover the upper 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 upper opening 411 and 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 body 41 by removing the inspection lid 422 from the inner lid body 421 without removing the screwed inner lid body 421 .

The base plate 43 is attached to the bottom of the tank body 41 . The base plate 43 shown in this embodiment is made 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. 6) projecting from the bottom of the base plate 43, thereby supporting the tank. It has a function of fixing the body 41 to the toilet bowl body 21 .

FIG. 7 shows a mounting structure between the tank body 41 and the base plate 43. As shown in FIG. A circular lower surface opening 413 is formed in 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 part that constitutes the valve seat of the flapper valve 4d (not shown in FIG. 7), which is one of the internal parts of the tank body 41, and has a flange portion 461 that is larger in diameter than the bottom opening 413. have. The valve seat 46 is mounted from the inside of the tank body 41 with a packing 46 a interposed between the flange portion 461 and the tank body 41 .

The valve seat 46 integrally has a cylindrical portion 462 having a male thread on the outer peripheral surface below 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 46 b from the outside of the tank body 41 onto a cylindrical portion 462 protruding from the bottom opening 413 .

On the other hand, a circular opening 432 is provided in the central portion of the base plate 43 , and the cylindrical portion 462 of the valve seat 46 protruding from the bottom surface of the tank body 41 is inserted through this opening 432 . The base plate 43 is clamped between the tightening nut 46c and the tank body 41 by screwing the tightening nut 46c into the cylindrical portion 462 protruding downward from the opening 432 . Thereby, the base plate 43 is fixed to the lower portion 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 bottom surface into tank mounting holes (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 . A 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 so that the flush water in the tank body 41 can be supplied to the toilet body 21 .

The anti-condensation material 44 is made of foamed polystyrene resin or the like and is formed into a shape along the outer peripheral surface of the tank body 41 . The anti-condensation material 44 shown in this embodiment is divided into a front anti-condensation material 441 and a rear anti-condensation material 442, which are mounted on the outer peripheral surface of the tank body 41 so as to sandwich the tank body 41 from the front and rear directions. . The anti-condensation material 44 has a height at least corresponding to the water level of the wash water stored in the tank body 41 .

Since the anti-condensation material 44 is divided into the front anti-condensation material 441 and the rear anti-condensation material 442 in the front-rear direction, a draft angle for releasing the mold from the mold is provided in the front-rear direction. Draft is not provided in As a result, the anti-condensation material 44 formed by combining the front anti-condensation material 441 and the rear anti-condensation material 442 has surfaces extending vertically along the vertical direction on the front side and the rear side of the toilet bowl cleaning tank 4 . can be formed. As a result, even if the thickness of the toilet bowl cleaning tank 4 is reduced, there is no fear of reducing the tank volume of the toilet bowl cleaning tank 4 due to the draft angle of the anti-condensation material. Moreover, since the tank main body 41 shown in the present embodiment is also not provided with a vertical draft angle, it is possible to further reduce the thickness of the toilet bowl cleaning tank 4 .

As shown in FIG. 6, the reinforcing frame 45 shown in this embodiment includes metal side frame members 451 arranged on both side surfaces of the toilet bowl cleaning tank 4 and metal frame members 451 extending in the width direction on the front side of the toilet bowl cleaning tank 4 . and a metal reinforcing stay 452 arranged in the . In FIG. 6, the toilet body 21 is indicated by broken lines, and the illustration of the toilet seat 22, the toilet lid 23, the functional part 24 of the toilet device, and the tank cover 5 on the toilet body 21 is omitted.

The side frame members 451 are fixed to both widthwise end faces 43a (see FIG. 4) of the base plate 43 by fixing screws 45a. The side frame member 451 is arranged so as to cover the side surface of the toilet bowl cleaning tank 4 over a range 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 divided into two by being attached to the base plate 43 so that the front side condensation preventive material 441 and the rear side condensation preventive material 442 do not open forward and backward. The anti-condensation 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. As a result, the left and right side frame members 451 are connected to each other by the reinforcing stays 452 , thereby preventing the side frame members 451 from expanding in the left-right direction due to springback or the like occurring in the side frame members 451 .

The reinforcing frame 45 functions to receive the load when the user leans against the tank cover 5 and prevent the load from directly acting 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 . Since the side frame member 451 is fixed to the base plate 43 which is stronger 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 anti-condensation material 44 divided in the longitudinal direction also has a draft angle in the longitudinal direction, as shown in FIG. and a recess 44b for receiving the side frame member 451. As shown in FIG. Since the recesses 44a and 44b can suppress the amount of forward protrusion of the reinforcing frame 45, even if the reinforcing frame 45 is provided, the tank volume of the tank body 41 does not decrease, and the toilet bowl cleaning tank 4 can be made thinner. can do.

2 to 4, 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 rear of the toilet bowl cleaning tank 4, and an upper portion of the toilet bowl cleaning tank 4. and an upper cover 53 that covers the . As shown in FIG. 6, the outer peripheral surface of the tank main body 41 of the toilet bowl cleaning tank 4 extends straight in the vertical direction and becomes a surface perpendicular to the floor surface f1. can also be arranged along the front and rear surfaces of the tank body 41 and perpendicular to the floor surface f1. Therefore, the front end P2 of the tank cover 5 shown in FIG. As a result, the tank cover 5 can be brought as close as possible to the toilet bowl cleaning tank 4 whose depth dimension is reduced, so that the maximum depth dimension Db (see FIG. 1) of the tank cover 5 is also reduced.

The front cover 51 is arranged above the toilet body 21 and between the functional part 24 of the toilet seat device on the toilet body 21 and the toilet cleaning tank 4 . As shown in FIG. 3, the rear end surface 241 of the functional portion 24 on the toilet body 21 is curved in the width direction so as to be concave forward. The front cover 51 is curved in the width direction so as to be convex forward so as to match the curved surface of the rear end surface 241 of the functional portion 24 . Therefore, compared with the case where the front cover 51 has a flat surface, the tank volume of the toilet bowl cleaning tank 4 can be ensured by the portion curved forward. A front end P2 of the tank cover 5 shown in FIG. 1 is a portion where the front cover 51 protrudes most forward.

The rear cover 52 has approximately the same height as the toilet bowl cleaning tank 4 . As shown in FIG. 4, the rear cover 52 is screwed to side frame members 451 provided on both sides of the toilet bowl cleaning tank 4 by fixing screws 52a. The front cover 51 and the upper cover 53 are provided so as to be removable from the rear cover 52 . As a result, the entire toilet bowl cleaning tank 4 is shielded by the tank cover 5, so that the appearance is improved and the design is improved.

As shown in FIGS. 2 and 4, the lower part of the toilet bowl cleaning tank 4 and the rear part of the toilet bowl 2 are covered with a pair of left and right lower covers 54 assembled in an L shape. As a result, the piping parts (not shown) disposed behind the toilet bowl 2 are hidden, and the rear side of the toilet bowl 2 is unified into a thin, substantially rectangular parallelepiped shape extending downward from the toilet bowl cleaning device 3. further improved.

The front cover 51 of the tank cover 5 is detachably attached to the rear cover 52 by, for example, screws, magnets, hook-and-loop fasteners, or the like. Therefore, when performing maintenance on the toilet bowl cleaning tank 4 , the toilet bowl cleaning tank 4 can be easily accessed by removing the front cover 51 from the rear cover 52 . At this time, since it is not necessary to remove the toilet bowl cleaning tank 4 from the toilet body 21, maintenance work can be easily performed.

The front cover 51 shown in this embodiment can be removed upward from the rear cover 52 . As a result, while the toilet seat 22, the toilet lid 23, and the functional portion 24 of the toilet seat device arranged in front of the lower part of the tank cover 5 are attached to the toilet body 21, the front cover 51 is removed and the toilet cleaning tank 4 is removed. Access becomes possible, and the maintainability of the toilet bowl cleaning tank 4 can be further improved.

Here, when the width of the tank cover 5 is W, and the height of the tank cover 5 is H, the relationship between the forward dimension (horizontal distance Da) of the toilet device 1 is Da:W:H=10:5. A ratio of 4:5.7 is preferred. Since the height of the tank cover 5 is larger than the width, the height of the toilet cleaning tank 4 can be increased accordingly. As a result, even if the toilet bowl cleaning tank 4 is made thinner and has a smaller cross-sectional area, the height of the toilet bowl cleaning tank 4 can be increased, so that the tank capacity can be secured. In addition, by increasing the height of the toilet bowl cleaning tank 4, the water head pressure is increased, so the momentum of the flush water is also increased.

The width W is the dimension of the portion of the tank cover 5 that protrudes most in the left-right direction. In the tank cover 5 shown in this embodiment, the front cover 51 is wider than the rear cover 52, so the width W of the tank cover 5 is the width of the front cover 51 (see FIG. 4). The height H is the dimension from the upper surface 21a of the toilet body 21 to which the toilet cleaning tank 4 is fixed to the portion of the tank cover 5 that protrudes most upward. In the tank cover 5 shown in this embodiment, the front cover 51 protrudes above the rear cover 52 and the upper cover 53, so the height H of the tank cover 5 is the vertical dimension of the front cover 51 ( See Figure 4).

According to such a toilet device 1, since the toilet bowl cleaning tank 4 has a vertical side wall surface in the vertical direction, the maximum depth dimension Db of the tank cover 5 can be easily reduced while securing a tank volume of 3 L (liters) or more. It is possible to reduce the size, and it becomes easy to satisfy the above relationship of Db≦Da/5.

In the toilet device 1 shown in the above embodiment, the toilet bowl cleaning tank 4 has a structure that does not have a vertical draft. Therefore, even in the case of having a structure in which the width increases from the bottom to the top, the tank volume of the toilet bowl cleaning tank 4A of 3 L (liter) or more is secured, and the relationship of Db ≤ Da/5 is satisfied. By filling, the forward dimension Da of the toilet device 1A can be reduced.

However, in this case, since the toilet bowl cleaning tank 4A has a vertical draft angle, the front surface 50a and the rear surface 50b of the tank cover 5A are also inclined in the vertical direction. For this reason, reducing the maximum depth dimension Db of the tank cover 5 while securing a tank volume of 3 L (liters) or more for the toilet bowl cleaning tank 4 without changing the size of the toilet bowl 21b is effective for the toilet device 1. A little more difficult than the case.
