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 arranged behind the toilet bowl 2. In the following description, the front-back direction when viewed from the user seated on the toilet bowl 2 is referred to as the front-back direction. Further, the width direction is defined as the left-right direction when viewed from the user seated on the toilet bowl 2. Further, the vertical direction along the vertical direction with respect to the floor surface f1 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. There is. Side covers 211 are detachably attached to both side surfaces of the rear portion of the toilet bowl body 21 by a hook-and-loop fastener or the like to shield the rear portion of the toilet bowl body 21.

The toilet bowl cleaning device 3 is arranged behind the toilet bowl main body 21. The toilet bowl cleaning device 3 includes a toilet bowl cleaning tank 4 and a tank cover 5 which is an exterior body of the toilet bowl cleaning tank 4.

The tank cover 5 shown in the present embodiment 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 cover 53 that covers the upper part of the toilet bowl cleaning tank 4. And have. The front cover 51 and the upper cover 53 are detachably attached 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 rear side of the toilet bowl 2 below the toilet bowl cleaning tank 4 is covered with a pair of left and right lower covers 54. As a result, the piping parts (not shown) and the like arranged on the rear side of the toilet bowl 2 are blinded, and the rear side of the toilet bowl 2 has a thin box shape extending downward from the toilet bowl cleaning device 3, which is a design. A sense of unity is created and the design is further improved.

As shown in FIG. 3, the toilet bowl cleaning tank 4 includes a tank main body 41, an inner lid 42, a base plate 43, a dew-proof material 44, and a reinforcing frame 45. In FIG. 3, only the toilet body 21 of the toilet 2 is shown by a broken line, and the toilet seat 22, the toilet lid 23, and the functional unit 24 are not shown.

The tank body 41 is made of a blow molded product. The upper surface 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, 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 the mold release in the vertical direction as in 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 perpendicularly to the floor surface f1 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. By reducing the thickness of the tank body 41, 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).

The tank body 41 shown in the present embodiment is formed longer in the left-right direction (width direction) than in the front-rear direction (depth direction). Specifically, the tank body 41 is formed so that the ratio of the length (width) in the left-right direction to the length (depth) in the front-rear direction is 5.4: 2.

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 is made of a resin that is harder than the tank body 41, and has a planar shape 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 of the rear portion of the toilet bowl body 21 by a pair of tightening bolts 431 (see FIG. 3) protruding from the bottom of the base plate 43, thereby supporting the tank body. It has a function of fixing the 41 to the toilet 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. 4), 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 so as to sandwich the packing 46a 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 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.

In the base plate 43 fixed to the tank body 41, a pair of tightening bolts 431 (see FIG. 3) projecting from the lower surface are inserted into a tank mounting hole (not shown) provided on the upper surface 21a of the toilet body 21. It is fixed. 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 borders the abutting surfaces 441a and 442a of the front-side dew-proof material 441 and the rear-side dew-proof material 442 arranged on both side surfaces (both end surfaces in the width direction of the dew-proof material 44). It is divided into two in the front-back direction. Specifically, the dew-proof material 44 has an under portion (a convex portion or a front-rear portion protruding in a direction intersecting the front-rear direction) in the front-rear direction of both side portions (a portion connecting the front surface portion and the rear surface portion of the dew-proof material 44). It is divided in the front-rear direction without having a recess (recessed in the direction intersecting the direction). The dew-proof material 44 is attached to the outer peripheral surface of the tank body 41 so as to sandwich the tank body 41 from the front-rear direction by the front-side dew-proof material 441 and the rear-side dew-proof material 442. 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 parts in the front-rear direction in the front-rear direction and the front-side dew-proof material 441 and the rear-side dew-proof material 442 without having an under portion in the front-rear direction on both side portions, the dew-proof material 44 is released from the mold. The draft is provided in the front-rear direction, and is not provided in the vertical direction unlike the conventional dew-proof material. 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 as in the conventional case. 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, the toilet bowl cleaning tank 4 is further thinned, and the dimensions of the toilet bowl device 1 in the front-rear direction ( It is possible to further reduce the above-mentioned dimensions).

The butt surface 441a of the front dew-proof material 441 and the butt surface 442a of the rear dew-proof material 442 shown in the present embodiment extend linearly along the vertical direction to the central portions of both sides of the dew-proof material 44. Although they are arranged, these abutting surfaces 441a and 442a may be arranged at any position of the dew-proof material 44 as long as the under portions are not formed in the front-rear direction of both side portions, and are arranged on the side surface of the dew-proof material 44. Can be placed on both sides of the. Further, for example, although not shown, the front dew-proof material 441 and the rear dew-proof material 442 are each formed in an L shape in a plan view, and by combining them, a storage space for the tank body 41 is provided inside. It may be formed. Further, the butt surfaces 441a and 442a do not necessarily have to extend linearly along the vertical direction.

By dividing the dew-proof material 44 into two in the front-rear direction, as shown in FIG. 5, the dew-proof material 44 can have a convex portion or a concave portion along the vertical direction on the rear surface side of the dew-proof material 44. Moreover, since the drafts of the front dew-proof material 441 and the rear dew-proof material 442 are provided on both side surfaces of the dew-proof material 44 along the front-rear direction, the dew-proof material is divided in the left-right direction as compared with the case where the dew-proof material is divided in the left-right direction. The amount of decrease in the volume of the inner space of the dew-proof material 44 due to the draft is reduced, and the ink volume of the tank body 41 can be secured accordingly.

As shown in FIG. 5, in the toilet bowl cleaning tank 4 shown in the present embodiment, water is supplied from a flexible pressure-resistant hose between the tank body 41 and the dew-proof material 44 (rear side dew-proof material 442). The hose 6 is housed. Therefore, the water supply hose 6 is covered with the dew-proof material 44 to insulate it, and the occurrence of dew condensation on the outer surface is suppressed. One end of the water supply hose 6 is connected to a ball tap 4a (see FIG. 2) arranged in the tank body 41, and the other end is the lower end of the dew-proof material 44 (rear-side dew-proof material 442), specifically, the prevention. It is exposed to the outside from the boundary between the dew material 44 (rear dew-proof material 442) and the base plate 43, extends downward, and is connected to the water supply pipe via a connection fitting (not shown).

In the water supply hose 6, the hose portion exposed to the outside from the lower end of the dew-proof material 44 is fitted and locked in the locking groove portion 433 provided on the base plate 43. As shown in FIG. 6, the locking groove portion 433 is formed in a U-shape that opens rearward at a corner portion on the rear side of the base plate 43 corresponding to the position of the water supply hose 6.

Two locking protrusions 434 and 435 are provided on the groove entrance side (rear side) of the locking groove portion 433. One locking protrusion 434 is integrally provided on the rear end side of the outer side wall portion 433a of the pair of side wall portions in the width direction constituting the locking groove portion 433. The locking protrusion 434 projects inward in the width direction of the base plate 43 so as to block the groove entrance side of the locking groove 433 from the side wall 433a over approximately half the groove width of the locking groove 433. ing. Further, the other locking protrusion 435 projects rearward along the inner side wall portion 433b so as to extend the side wall portion 433b.

The positions of the locking protrusions 434 and 435 in the height direction of the base plate 43 are different. One locking protrusion 434 is arranged at the lower end of the base plate 43 (locking groove 433) in the height direction, and the other locking protrusion 435 is located at the lower end of the base plate 43 (locking groove 433) in the height direction. It is located at the top. Therefore, the locking protrusions 434 and 435 are formed so that the protruding directions and the heights are staggered.

When fitting the water supply hose 6 into the locking groove 433, the water supply hose 6 is bent slightly diagonally and inserted between the two locking protrusions 434 and 435 from the side (rear) of the base plate 43. It can be done by. At this time, since it is not necessary to bend the water supply hose 6 at an acute angle or insert the water supply hose 6 into the locking groove portion 433 from the end portion, the water supply hose 6 can be easily attached.

As a specific construction method, first, a tank body 41 to which the base plate 43 is attached is prepared in advance, and one end of the water supply hose 6 is connected to the ball tap 4a (see FIG. 2) in the tank body 41. The other end side of the water supply hose 6 is arranged so as to extend downward along the rear surface of the tank body 41. After that, the rear dew-proof material 442 is attached to the rear surface of the tank body 41 by covering the water supply hose 6. As a result, the water supply hose 6 is accommodated between the tank body 41 and the dew-proof material 44 (rear-side dew-proof material 442).

According to this method, the water supply hose 6 can be housed in the dew-proof material 44 only by keeping the water supply hose 6 along the tank body 41. There is no need for troublesome work of inserting into the insertion hole of the dew-proof material 44, and the work of accommodating the water supply hose 6 inside the dew-proof material 44 can be easily performed. The water supply hose 6 is locked in the locking groove portion 433 of the base plate 43 as described above before or after attaching the rear dew-proof material 442.

As shown in FIG. 3, 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 and is arranged in.

The side frame members 451 are fixed to both end faces 43a 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 approximately 1/2 the height 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. Therefore, the side frame member 451 corresponds to the sandwiching member of the present invention.

The rear cover 52 of the tank cover 5 is screw-fixed to the side frame member 451. By attaching the front cover 51 and the upper cover 53 to the rear cover 52, the tank cover 5 is fixed to the toilet body 21 via the side frame member 451 and the base plate 43.

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 stays 452, and the side frame members 451 are prevented from spreading in the left-right direction due to the 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. 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 more robust than the tank body 41, the load transmitted from the reinforcing stay 452 can be effectively received and released to the toilet bowl 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. 3, the reinforcing stay 452 of the reinforcing frame 45 is accommodated 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.

The recess 44a accommodating the reinforcing stay 452 is arranged near the central portion in the vertical direction of the front dew-proof material 441. This portion corresponds to a portion where the user's back directly hits when the user leans against the tank cover 5. Since the dew-proof material 44 does not have a draft in the vertical direction, it is possible to provide a recess 44a in the width direction in the vicinity of the central portion in the vertical direction of the front dew-proof material 441.
